To the Stockholders of Adobe Systems Incorporated:

On behalf of the board of directors of Adobe Systems Incorporated, a Delaware corporation, we are pleased to deliver this joint proxy statement/prospectus for the proposed merger combining Adobe and Macromedia, Inc., a Delaware corporation. A special meeting of stockholders of Adobe will be held on Wednesday, August 24, 2005 at 3:00 p.m., local time, at the principal executive offices of Adobe located at 345 Park Avenue, San Jose, California 95110, for the following purposes:

1.: To consider and vote upon the issuance of shares of Adobe common stock in the merger contemplated by the Agreement and Plan of Merger and Reorganization, dated as of April 17, 2005, among Adobe, Avner Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Adobe, and Macromedia, Inc.
2.: To consider and vote upon an adjournment of the special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1.
3.: To transact such other business as may properly come before the special meeting or any adjournment or postponement thereof.

The board of directors of Adobe has fixed July 19, 2005 as the record date for the determination of stockholders entitled to notice of, and to vote at, the special meeting and any adjournment or postponement thereof. Only holders of record of shares of Adobe common stock at the close of business on the record date are entitled to notice of, and to vote at, the special meeting. At the close of business on the record date, Adobe had outstanding and entitled to vote 492,276,674 shares of common stock.

Your vote is important. The affirmative vote of the holders of a majority of the votes cast in person or by proxy at the Adobe special meeting is required for approval of each of Proposal No. 1 regarding the issuance of shares of Adobe common stock in the merger and Proposal No. 2 regarding an adjournment of the special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1. Even if you plan to attend the special meeting in person, we request that you sign and return the enclosed proxy card or vote by telephone or by using the Internet as instructed on the enclosed proxy card, and thus ensure that your shares will be represented at the special meeting if you are unable to attend. If you sign, date and mail your proxy card without indicating how you wish to vote, your proxy will be counted as a vote in favor of the issuance of shares of Adobe common stock in the merger and an adjournment of the Adobe special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1. If you fail to return your proxy card or vote by telephone or by using the Internet, the effect will be that your shares will not be counted for purposes of determining whether a quorum is present at the special meeting.

QUESTIONS AND ANSWERS ABOUT THE MERGER

Unless specifically stated otherwise, the following information and all other information contained in this joint proxy statement/prospectus, including that regarding the exchange ratio pursuant to the merger agreement, gives effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

Q: What is the merger?

A:: Adobe and Macromedia have entered into an Agreement and Plan of Merger and Reorganization, dated April 17, 2005, which is referred to in this joint proxy statement/prospectus as the merger agreement, that contains the terms and conditions of the proposed business combination of Adobe and Macromedia. Under the merger agreement, Macromedia and Avner Acquisition Sub, Inc., a wholly owned subsidiary of Adobe, will merge, with Macromedia surviving as a wholly owned subsidiary of Adobe, which transaction is referred to as the merger. The shares of Adobe common stock issued to Macromedia stockholders in connection with the merger are expected to represent approximately 17.5% of the outstanding shares of Adobe common stock immediately following the consummation of the merger, based on the number of shares of Adobe common stock and Macromedia common stock outstanding on July 19, 2005, assuming that no Macromedia or Adobe stock options are exercised after July 19, 2005 and prior to the effective time of the merger. For a more complete description of the merger, please see the section entitled "Adobe Proposal No. 1 and Macromedia Proposal No. 1—The Merger" on page 43 of this joint proxy statement/prospectus.

Q: Why are the two companies proposing to merge?

A:: Adobe's mission has always been to help people and businesses communicate better. Macromedia's mission has been to provide a rich media experience. Together, we share a vision for the future and with the combination of the two companies—our products, technologies and people—we hope to enable the creation and delivery of compelling content and experiences across multiple operating systems, devices and media. Both companies have great opportunities ahead of them and believe that together, they will be better able to achieve their combined vision with significant synergy. For a discussion of our reasons for the merger, we urge you to read the information in the section entitled "Adobe Proposal No. 1 and Macromedia Proposal No. 1—The Merger—Reasons for the Merger" on page 47 of this joint proxy statement/prospectus.

Q: Why am I receiving this joint proxy statement/prospectus?

A:: You are receiving this joint proxy statement/prospectus because you have been identified as a stockholder of either Adobe or Macromedia, and thus you are entitled to vote at such company's special meeting. This document serves as both a joint proxy statement of Adobe and Macromedia, used to solicit proxies for the special meetings, and as a prospectus of Adobe, used to offer shares of Adobe common stock in exchange for shares of Macromedia common stock pursuant to the terms of the merger agreement. This document contains important information about the merger and the special meetings of Adobe and Macromedia, and you should read it carefully.

Q: What is required to consummate the merger?

A:: To consummate the merger, Adobe stockholders must approve the issuance of shares of Adobe common stock in the merger, which approval requires the affirmative vote of the holders of a majority of the votes cast in person or by proxy at the Adobe special meeting. In addition, Macromedia stockholders must adopt the merger agreement, which adoption requires the affirmative vote of the holders of a majority of the voting power of the shares of Macromedia common stock outstanding on the record date for the Macromedia special meeting. In addition to

the receipt of stockholder approval and appropriate regulatory approvals, including antitrust clearance, each of the other closing conditions set forth in the merger agreement must be satisfied or waived. For a more complete description of the closing conditions under the merger agreement, we urge you to read the section entitled "The Merger Agreement—Conditions to the Merger" on page 99 of this joint proxy statement/prospectus and the merger agreement attached to this joint proxy statement/prospectus as Annex A.

Q: What will Macromedia stockholders receive in the merger?

A:: As a result of the merger, Macromedia stockholders will receive 1.38 shares of Adobe common stock for each share of Macromedia common stock they own. For example, if you own 100 shares of Macromedia common stock, you will receive 138 shares of Adobe common stock in exchange for your Macromedia shares. The number of shares of Adobe common stock to be issued for each share of Macromedia common stock is fixed and will not be adjusted based upon changes in the value of Macromedia common stock or Adobe common stock. As a result, the value of the Adobe shares you will receive in the merger will not be known before the merger, and will go up or down as the market price of Adobe common stock goes up or down. We encourage you to obtain current market quotations of Macromedia common stock and Adobe common stock. For a more complete description of what Macromedia stockholders will receive in the merger, please see the section entitled "The Merger Agreement—Manner and Basis of Converting Shares" on page 86 of this joint proxy statement/prospectus.

Q: What will Macromedia option holders receive in the merger?

A:: Subject to certain exceptions, at the effective time of the merger, each Macromedia stock option that is outstanding and unexercised immediately prior to the effective time will be converted into an option to purchase Adobe common stock and Adobe will assume that stock option (or will replace that stock option by issuing a materially equivalent replacement stock option to purchase Adobe common stock) in accordance with the terms of the applicable Macromedia stock option plan and terms of the stock option agreement relating to that Macromedia stock option. For more information, please see "The Merger Agreement—Macromedia Stock Options" on page 92.

Q: What are the material federal income tax consequences of the merger to me?

A:: The merger has been structured to qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and it is a closing condition to the merger that Adobe and Macromedia receive opinions of their respective counsel regarding such qualification. As a result of the merger's anticipated qualification as a reorganization, Macromedia stockholders will not recognize gain or loss for United States federal income tax purposes upon the exchange of shares of Macromedia common stock for shares of Adobe common stock, except with respect to cash received in lieu of fractional shares of Adobe common stock.

Tax matters are very complicated, and the tax consequences of the merger to a particular stockholder will depend in part on such stockholder's circumstances. Accordingly, we urge you to consult your own tax advisor for a full understanding of the tax consequences of the merger to you, including the applicability and effect of federal, state, local and foreign income and other tax laws.

For more information, please see the section entitled "Adobe Proposal No. 1 and Macromedia Proposal No. 1—The Merger—Material Federal Income Tax Consequences" on page 82 of this joint proxy statement/prospectus.

Q: How does Adobe's board of directors recommend that I vote?

A:: After careful consideration, Adobe's board of directors unanimously recommends that Adobe stockholders vote "FOR" Proposal No. 1 to approve the issuance of shares of Adobe common stock in the merger and "FOR" Proposal No. 2 to adjourn the Adobe special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1. For a description of the reasons underlying the recommendations of Adobe's board, see the sections entitled "Adobe Proposal No. 1 and Macromedia Proposal No. 1—The Merger—Mutual Reasons for the Merger" on page 48 and "—Adobe's Reasons for the Merger" on page 49, and the section entitled "Adobe Proposal No. 2—Possible Adjournment of the Special Meeting" on page 109.

Q: How does Macromedia's board of directors recommend that I vote?

A:: After careful consideration, Macromedia's board of directors unanimously recommends that the Macromedia stockholders vote "FOR" Proposal No. 1 to adopt the merger agreement and "FOR" Proposal No. 2 to adjourn the Macromedia special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1. For a description of the reasons underlying the recommendations of Macromedia's board, see the sections entitled "Adobe Proposal No. 1 and Macromedia Proposal No. 1—The Merger—Mutual Reasons for the Merger" on page 48 and "—Macromedia's Reasons for the Merger" on page 51, and the section entitled "Macromedia Proposal No. 2—Possible Adjournment of the Special Meeting" on page 110.

Q: What risks should I consider in deciding whether to vote in favor of the share issuance or the adoption of the merger agreement?

A:: You should carefully review the section of this joint proxy statement/prospectus entitled "Risk Factors" beginning on page 21, which presents risks and uncertainties related to the merger, Adobe and Macromedia.

Q: When do you expect the merger to be consummated?

A:: We anticipate that the consummation of the merger will occur in Fall 2005, but we cannot predict the exact timing. For more information, please see the section entitled "The Merger Agreement—Conditions to the Merger" on page 99.

Q: What do I need to do now?

A:: We urge you to read this joint proxy statement/prospectus carefully, including its annexes, and to consider how the merger affects you. You may provide your proxy instructions in three different ways. First, you can mail your signed proxy card in the enclosed return envelope. Alternatively, you can provide your proxy instructions via the toll-free call center set up for this purpose at (800) 690-6903. Finally, you can provide your proxy instructions via the Internet at www.proxyvote.com. Please provide your proxy instructions only once and as soon as possible so that your shares can be voted at the special meeting of Adobe stockholders or special meeting of Macromedia stockholders, as applicable.

Q: What happens if I do not return a proxy card or otherwise provide proxy instructions?

A:: If you are an Adobe stockholder, the failure to return your proxy card or otherwise provide proxy instructions could be a factor in establishing a quorum for the special meeting of Adobe stockholders, which is required to transact business at the meeting. If you are a Macromedia stockholder, the failure to return your proxy card or otherwise provide proxy instructions will have

the same effect as voting against the adoption of the merger agreement and could be a factor in establishing a quorum for the special meeting of Macromedia stockholders, which is required to transact business at the meeting.

Q: May I vote in person?

A:: If your shares of Adobe common stock or Macromedia common stock are registered directly in your name with Adobe's or Macromedia's transfer agent, respectively, you are considered, with respect to those shares, the stockholder of record, and the proxy materials and proxy card are being sent directly to you by Adobe or Macromedia, respectively. If you are an Adobe stockholder of record, you may attend the special meeting of Adobe stockholders to be held on August 24, 2005 and vote your shares in person, rather than signing and returning your proxy card or otherwise providing proxy instructions. If you are a Macromedia stockholder of record, you may attend the special meeting of Macromedia stockholders to be held on August 24, 2005 and vote your shares in person, rather than signing and returning your proxy card or otherwise providing proxy instructions.

If your shares of Adobe common stock or Macromedia common stock are held in a brokerage account or by another nominee, you are considered the beneficial owner of shares held in "street name," and the proxy materials are being forwarded to you together with a voting instruction card. As the beneficial owner, you are also invited to attend the special meeting of Adobe stockholders or the special meeting of Macromedia stockholders, respectively. Since a beneficial owner is not the stockholder of record, you may not vote these shares in person at the applicable special meeting unless you obtain a "legal proxy" from the broker, trustee or nominee that holds your shares, giving you the right to vote the shares at the meeting.

Q: If my shares are held in "street name" by my broker, will my broker vote my shares for me?

A:: Your broker will not be able to vote your shares without instructions from you. You should instruct your broker to vote your shares, following the procedure provided by your broker.

Q: May I change my vote after I have provided proxy instructions?

A:: Yes. You may change your vote at any time before your proxy is voted at the Adobe or Macromedia special meeting, as applicable. You can do this in one of three ways. First, you can send a written notice stating that you would like to revoke your proxy. Second, you can submit new proxy instructions either on a new proxy card, by telephone or via the Internet. Third, you can attend the meeting and vote in person. Your attendance alone will not revoke your proxy. If you have instructed a broker to vote your shares, you must follow directions received from your broker to change those instructions.

Q: Should I send in my stock certificates now?

A:: No. If you are a Macromedia stockholder, after the merger is consummated, you will receive written instructions from the exchange agent explaining how to exchange your stock certificates representing shares of Macromedia common stock for certificates representing shares of Adobe common stock. You will also receive a cash payment in lieu of any fractional share of Adobe common stock. Adobe stockholders will not exchange their stock certificates.

Q: Am I entitled to appraisal rights?

A:: Under Delaware corporate law, holders of Macromedia common stock are not entitled to appraisal rights in connection with the merger because both Adobe common stock and Macromedia

common stock are listed on the NASDAQ National Market. Under Delaware corporate law, Adobe stockholders are not entitled to appraisal rights in connection with the merger.

Q: Who is paying for this proxy solicitation?

A:: Adobe and Macromedia are conducting this proxy solicitation and will bear the cost of soliciting proxies, including the preparation, assembly, printing and mailing of this joint proxy statement/prospectus, the proxy card and any additional information furnished to stockholders. Adobe has engaged the services of Innisfree M&A Incorporated to distribute proxy solicitation materials to brokers, banks and other nominees and to assist in the solicitation of proxies from Adobe stockholders. Macromedia has retained The Altman Group, Inc. to aid in Macromedia's proxy solicitation process. Adobe estimates that its proxy solicitor fees will be approximately $15,000 and Macromedia estimates that its proxy solicitor fees will be approximately $3,500. Adobe and Macromedia may also reimburse brokerage houses and other custodians, nominees and fiduciaries for their costs of forwarding proxy and solicitation materials to beneficial owners.

The Merger (Page 86)

In the merger, Avner Acquisition Sub, Inc., a wholly owned subsidiary of Adobe, will merge with and into Macromedia, and Macromedia will become a wholly owned subsidiary of Adobe. Holders of Macromedia common stock and options will become holders of Adobe common stock and options, respectively, following the merger. The shares of Adobe common stock issued to Macromedia stockholders in connection with the merger are expected to represent approximately 17.5% of the outstanding shares of Adobe common stock immediately following the consummation of the merger, based on the number of shares of Adobe common stock and Macromedia common stock outstanding on July 19, 2005, assuming that no Macromedia or Adobe stock options are exercised after July 19, 2005 and prior to the effective time of the merger.

Manner and Basis of Converting Shares (Page 86)

If you are a Macromedia stockholder, you will receive 1.38 shares of Adobe common stock in exchange for each share of Macromedia common stock you own. The exchange ratio is fixed and, regardless of fluctuations in the market price of Adobe's or Macromedia's common stock, will not change between now and the date the merger is consummated, subject to any adjustments for changes in the number of outstanding shares of Adobe or Macromedia by reason of future stock splits, division of shares, stock dividends or other similar transactions.

Treatment of Stock Options (Page 92)

The merger agreement provides that, subject to certain exceptions, at the effective time of the merger, each Macromedia stock option that is outstanding and unexercised immediately prior to the effective time will be converted into an option to purchase Adobe common stock and Adobe will assume that stock option (or will replace that stock option by issuing a materially equivalent replacement stock option to purchase Adobe common stock) in accordance with the terms of the applicable Macromedia stock option plan and terms of the stock option agreement relating to that Macromedia stock option.

Risks Relating to the Merger (Page 21)

In evaluating the merger agreement or the issuance of shares of Adobe common stock in the merger, you should carefully read this joint proxy statement/prospectus and especially consider the factors discussed in the section entitled "Risk Factors—Risks Relating to the Merger" on page 21.

Reasons for the Merger

Mutual Reasons (Page 48). Adobe and Macromedia believe that the two companies together can meet more of our customers' needs by integrating our products and technologies to help our customers

communicate better. We believe that combined company has the opportunity to define a robust technology platform that delivers compelling, rich content across a wide range of devices and operating systems. Moreover, we believe that the software industry is in a period of consolidation and that there is a developing trend for customers to source a larger portion of their software needs from a smaller number of suppliers. We believe that the combined company will have the scale to better compete in this environment.

Adobe's Reasons (Page 49). The Adobe board of directors approved the merger based on a number of factors, including, among other factors, the following:

•: the complementary nature of Adobe's and Macromedia's product lines;
•: the potential opportunity for the two companies to integrate their software solutions to meet a wider set of customer needs and to combine their technological resources to develop new products with increased functionality and bring them to market faster;
•: the board's and management's assessment that the merger and Macromedia's operating strategy are consistent with Adobe's long-term operating strategy to grow into new markets, particularly in the non-PC device and enterprise segments;
•: the competitive and market environments in which Adobe and Macromedia operate, including Microsoft's position in those environments, and the potential for the merger to enhance Adobe's ability to compete effectively in those environments; and
•: the opinion of Adobe's financial advisor that, as of April 17, 2005 and based on and subject to the factors and assumptions set forth in the opinion, the exchange ratio pursuant to the merger agreement was fair to Adobe from a financial point of view.

Macromedia's Reasons (Page 51). The Macromedia board of directors approved the merger based on a number of factors, including, among other factors, the following:

•: the complementary nature of Adobe's and Macromedia's product lines;
•: the potential opportunity for the two companies to combine their technological resources to develop new products with increased functionality and bring them to market faster;
•: the potential availability of greater resources for product marketing and distribution;
•: the board's and management's assessment that the merger and Adobe's operating strategy are consistent with Macromedia's long-term operating strategy to grow its business by expanding the scope, platform coverage and depth and breadth of product offerings;
•: the importance of scale in the increasingly competitive market environments in which Macromedia and Adobe operate, and the potential for the merger to enhance Macromedia's ability to compete effectively in those environments;
•: providing Macromedia stockholders with shares of Adobe common stock in a tax-free exchange at a premium over the market price for Macromedia common stock prior to the announcement of the merger; and
•: the opinion of Macromedia's financial advisor that, as of April 17, 2005 and based on and subject to the assumptions, qualifications and limitations set forth in the opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to holders of shares of Macromedia common stock.

Opinions of Financial Advisors

Opinion of Adobe's Financial Advisor (Page 53). Goldman, Sachs & Co. delivered its opinion to Adobe's board of directors that, as of April 17, 2005 and based on and subject to the factors and assumptions set forth therein, the exchange ratio of 0.69 shares of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement was fair to Adobe from a financial point of view. The exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

The full text of the written opinion of Goldman Sachs, dated April 17, 2005, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex D. Goldman Sachs provided its opinion for the information and assistance of Adobe's board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Adobe common stock should vote with respect to the issuance of shares of Adobe common stock in the merger. Adobe urges you to read the entire opinion carefully.

Opinion of Macromedia's Financial Advisor (Page 61). Morgan Stanley & Co. Incorporated delivered its opinion to Macromedia's board of directors that, as of April 17, 2005 and based upon and subject to the assumptions, qualifications and limitations set forth therein, the exchange ratio of 0.69 of a share of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement was fair from a financial point of view to the stockholders of Macromedia. The exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

The full text of the written opinion of Morgan Stanley & Co. Incorporated, dated April 17, 2005, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex E. Morgan Stanley provided its opinion for the information and assistance of Macromedia's board of directors in consideration of the merger and the merger agreement. The Morgan Stanley opinion is not a recommendation as to how any holder of Macromedia common stock should vote with respect to the adoption of the merger agreement. Macromedia urges you to read the entire opinion carefully.

Interests of Macromedia's Executive Officers and Directors in the Merger (Page 73)

When considering the recommendations by the Macromedia board of directors, you should be aware that a number of Macromedia's executive officers and directors have interests in the merger that are different from those of other Macromedia stockholders.

Restrictions on Resales (Page 85)

The merger agreement provides that Macromedia will use commercially reasonable efforts to obtain a signed affiliate agreement from each person who may be deemed to be an affiliate of Macromedia. The merger agreement provides that Adobe will not issue shares of Adobe common stock to any "affiliate" of Macromedia who has not provided Adobe with a signed affiliate agreement. The affiliate agreements provide, among other things, that these persons will not sell, transfer or otherwise dispose of their shares of Adobe common stock received in the merger unless they do so in compliance with securities laws governing sales by affiliates.

Limitation on the Solicitation, Negotiation and Discussion by Macromedia of Other Acquisition Proposals (Page 96)

Macromedia has agreed to a number of limitations with respect to soliciting, negotiating and discussing acquisition proposals involving persons other than Adobe, and to certain related matters.

Change of Board Recommendation (Page 94)

Subject to limited conditions, the board of directors of Macromedia or Adobe may withdraw or modify its recommendation in support of the adoption of the merger agreement or the issuance of shares of Adobe common stock in the merger, as the case may be. In the event that the board of directors of either company withdraws or modifies its recommendation in a manner adverse to the other company, the company whose board of directors withdrew or modified its recommendation may be required to pay a termination fee of $103.2 million to the other company.

Conditions to the Merger (Page 99)

The respective obligations of Adobe and Macromedia to consummate the merger are subject to the satisfaction of certain conditions.

Termination of the Merger Agreement (Page 101)

Either Adobe or Macromedia can terminate the merger agreement under certain circumstances, which would prevent the merger from being consummated.

Expenses and Termination Fees (Page 104)

Subject to limited exceptions, all fees and expenses incurred in connection with the merger agreement will be paid by the party incurring such expenses; provided, however, that Adobe and Macromedia will share equally all fees and expenses, other than attorneys' fees, incurred in connection with (1) the filing, printing and mailing of the registration statement on Form S-4 and this joint proxy statement/prospectus, and (2) the filing by the parties of the premerger notification and report forms relating to the merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, or the HSR Act.

A termination fee of $103.2 million may be payable by either Adobe or Macromedia to the other party upon the termination of the merger agreement under several circumstances.

Tax Matters (Page 82)

Cooley Godward LLP, outside counsel to Adobe, and Fenwick & West LLP, outside counsel to Macromedia, are expected to each issue a tax opinion to the effect that the merger will constitute a reorganization under Section 368 of the Internal Revenue Code of 1986, or the Code. In a reorganization, a Macromedia stockholder generally will not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of its shares of Macromedia common stock for shares of Adobe common stock. However, any cash received for any fractional share will result in the recognition of gain or loss as if such stockholder sold its fractional share. A Macromedia stockholder's tax basis in the shares of Adobe common stock that it receives in the merger will equal its current tax basis in its Macromedia common stock (reduced by the basis allocable to any fractional share interest for which it receives cash).

Tax matters can be complicated, and the tax consequences of the merger to you will depend on the facts of your own situation. You should consult your own tax advisors to fully understand the tax consequences of the merger to you, including the applicability and effect of federal, state, local and foreign income and other tax laws.

Regulatory Approvals (Page 84)

To consummate the merger, Adobe and Macromedia must make filings and obtain approvals or clearances from antitrust regulatory authorities in the United States, certain countries in the European Union and other countries. The thirty-day waiting period under the HSR Act has been extended by a government request for additional information and documentary material until 30 days after Adobe and Macromedia have substantially complied with the request. In the United States, Adobe must also comply with applicable federal and state securities laws and the rules and regulations of the NASDAQ National Market in connection with the issuance of shares of Adobe common stock in the merger and the filing of this joint proxy statement/prospectus with the SEC.

Anticipated Accounting Treatment (Page 84)

The merger will be accounted for as a purchase transaction by Adobe for financial reporting and accounting purposes under U.S. generally accepted accounting principles. The results of operations of Macromedia will be included in the consolidated financial statements of Adobe from the consummation of the merger forward.

Appraisal Rights (Page 84)

Under Delaware corporate law, holders of Macromedia common stock are not entitled to appraisal rights in connection with the merger because both Adobe common stock and Macromedia common stock are listed on the NASDAQ National Market. Under Delaware corporate law, holders of Adobe common stock are not entitled to appraisal rights in connection with the merger.

MARKET PRICE AND DIVIDEND DATA

The following information gives effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

Adobe common stock and Macromedia common stock are listed on the NASDAQ National Market under the symbols "ADBE" and "MACR," respectively. The following tables present, for the periods indicated, the range of high and low per share sales prices for Adobe common stock and Macromedia common stock as reported on the NASDAQ National Market.

The following table presents the closing per share sales price of Adobe common stock and Macromedia common stock, as reported on the NASDAQ National Market, and the estimated equivalent per share price (as explained below) of Macromedia common stock on April 15, 2005, the last full trading day before the public announcement of the proposed merger, and on July 19, 2005:

		Adobe Common Stock			Macromedia Common Stock			Estimated Equivalent Macromedia Per Share Price
April 15, 2005.		$	30.33		$	33.45		$	41.86
July 19, 2005			29.31			39.71			40.45

The estimated equivalent per share price of a share of Macromedia common stock equals the exchange ratio of 1.38 multiplied by the price of a share of Adobe common stock. You may use this calculation to determine what your shares of Macromedia common stock will be worth if the merger is consummated. If the merger had occurred on July 19, 2005, you would have received a number of shares of Adobe common stock worth $40.45 for each share of Macromedia common stock you owned. The actual equivalent per share price of a share of Macromedia common stock that you will receive if the merger is consummated may be different from this price because the per share price of Adobe common stock on the NASDAQ National Market fluctuates continuously.

Following the consummation of the merger, Adobe common stock will continue to be listed on the NASDAQ National Market, and there will be no further market for the Macromedia common stock.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA
(in thousands, except per share data)

The following selected unaudited pro forma condensed combined financial information was prepared using the purchase method of accounting. The Adobe and Macromedia unaudited pro forma condensed combined balance sheet data assume that the merger of Adobe and Macromedia took place on June 3, 2005, and combines the Adobe historical consolidated balance sheet at June 3, 2005 with Macromedia's historical consolidated balance sheet at March 31, 2005. The Adobe and Macromedia unaudited pro forma condensed combined statements of income data assume that the merger of Adobe and Macromedia took place as of November 29, 2003. The unaudited pro forma condensed combined statements of income data for the fiscal year ended December 3, 2004 combines Adobe's historical consolidated statement of income for the fiscal year then ended with Macromedia's results of operations for the nine months ended December 31, 2004 and the three months ended March 31, 2004. The unaudited pro forma condensed combined statements of income data for the six months ended June 3, 2005 combines Adobe's historical consolidated statement of income for the six months then ended with Macromedia's historical consolidated statement of income for the six months ended March 31, 2005.

The selected unaudited pro forma condensed combined financial data are presented for illustrative purposes only and are not necessarily indicative of the combined financial position or results of operations of future periods or the results that actually would have been realized had the entities been a single entity during these periods. The selected unaudited pro forma condensed combined financial data as of and for the six months ended June 3, 2005 and for the fiscal year ended December 3, 2004 are derived from the unaudited pro forma condensed combined financial statements included elsewhere in this joint proxy statement/prospectus and should be read in conjunction with those statements and the related notes.

COMPARATIVE HISTORICAL AND PRO FORMA PER SHARE DATA

The following information gives effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

The information below reflects:

•: the historical net income, book value and cash dividends per share of Adobe common stock and the historical net income (loss), book value and cash dividends per share of Macromedia common stock in comparison with the unaudited pro forma net income, book value and cash dividends per share after giving effect to the proposed merger of Adobe with Macromedia on a purchase basis; and
•: the equivalent historical net income, book value and cash dividends per share attributable to 1.38 shares of Adobe common stock which will be received for each share of Macromedia common stock.

Because of different fiscal period ends, the unaudited pro forma condensed combined statements of income data for the six months ended June 3, 2005 combines Adobe's historical consolidated statement of income for the six months then ended with Macromedia's historical consolidated statement of income for the six months ended March 31, 2005. The unaudited pro forma condensed combined statements of income data for the fiscal year ended December 3, 2004 combines Adobe's historical consolidated statement of income for the fiscal year then ended with Macromedia's results of operations for the nine months ended December 31, 2004 and the three months ended March 31, 2004.

You should read the tables below in conjunction with the respective audited and unaudited consolidated financial statements and related notes of Adobe and Macromedia incorporated by reference in this joint proxy statement/prospectus and the unaudited pro forma condensed financial information and notes related to such consolidated financial statements included elsewhere in this joint proxy statement/prospectus.

All forward-looking statements are qualified in their entirety by this cautionary statement.

RISK FACTORS

You should consider the following factors in evaluating whether to approve the issuance of shares of Adobe common stock in the merger or whether to adopt the merger agreement, as the case may be. These factors should be considered in conjunction with the other information included or incorporated by reference by Adobe and Macromedia in this joint proxy statement/prospectus.

Risks Relating to the Merger

If we do not integrate our products, we may lose customers and fail to achieve our financial objectives.

Achieving the benefits of the merger will depend in part on the integration of Adobe's and Macromedia's products in a timely and efficient manner. In order for us to provide enhanced and more valuable products to our customers after the merger, we will need to integrate our product lines and development organizations. This will be difficult, unpredictable, and subject to delay because our products are highly complex, have been developed independently and were designed without regard to such integration. If we cannot successfully integrate our products and continue to provide customers with products and new product features in the future on a timely basis, we may lose customers and our business and results of operations may be harmed.

If we are not successful in integrating our organizations, we will not be able to operate efficiently after the merger.

Achieving the benefits of the merger will also depend in part on the successful integration of Adobe's and Macromedia's operations and personnel in a timely and efficient manner. The integration process requires coordination of different development and engineering teams, and involves the integration of systems, applications, policies, procedures, business processes and channel operations. This, too, will be difficult, unpredictable, and subject to delay because of possible cultural conflicts and different opinions on technical decisions and product roadmaps. If we cannot successfully integrate our operations and personnel, we will not realize the expected benefits of the merger.

Integrating our companies may divert management's attention away from our operations.

Successful integration of Adobe's and Macromedia's operations, products and personnel may place a significant burden on our management and our internal resources. The diversion of management attention and any difficulties encountered in the transition and integration process could harm our business, financial condition and operating results.

We expect to incur significant costs integrating the companies into a single business, and if such integration is not successful we may not realize the expected benefits of the merger.

We expect to incur significant costs integrating Macromedia's operations, products and personnel. These costs may include costs for:

•: employee redeployment, relocation or severance;
•: conversion of information systems;
•: combining research and development teams and processes;
•: reorganization or closures of facilities; and
•: relocation or disposition of excess equipment.

In addition, we expect to incur significant costs in connection with the merger. We do not know whether we will be successful in these integration efforts or in consummating the merger and cannot assure you that we will realize the expected benefits of the merger.

If we fail to retain key employees, the benefits of the merger could be diminished.

The successful combination of Adobe and Macromedia will depend in part on the retention of key personnel. There can be no assurance that Adobe will be able to retain its or Macromedia's key management, technical, sales and customer support personnel. If we fail to retain such key employees, we may not realize the anticipated benefits of the merger.

Our sales could decline if customer relationships are disrupted by the merger.

Our customers may not continue their current buying patterns during the pendency of, and following, the merger. Any significant delay or reduction in orders for Adobe's or Macromedia's products could harm the combined company's business, financial condition and results of operations. Customers may defer purchasing decisions as they evaluate the likelihood of successful integration of Adobe's and Macromedia's products and the combined company's future product strategy, or consider purchasing products of our competitors. Customers may also seek to modify or terminate existing agreements, or prospective customers may delay entering into new agreements or purchasing our products. In addition, by increasing the breadth of Adobe's and Macromedia's business, the merger may make it more difficult for the combined company to enter into relationships, including customer relationships, with strategic partners, some of whom may view the combined company as a more direct competitor than either Adobe or Macromedia as an independent company.

Because Macromedia stockholders will receive a fixed number of shares of Adobe common stock in the merger, rather than a fixed value, if the market price of Adobe common stock declines, Macromedia stockholders will receive consideration in the merger of lesser value.

Upon the consummation of the merger, each Macromedia share will be converted into the right to receive 1.38 shares of Adobe common stock, which exchange ratio gives effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005. Since the exchange ratio is fixed, the number of shares that Macromedia stockholders will receive in the merger will not change, even if the market price of Adobe common stock changes. In recent years, the stock market, in general, and the securities of technology companies, in particular, have experienced extreme price and volume fluctuations. These market fluctuations may adversely affect the market price of Adobe common stock. The market price of Adobe common stock upon and after the consummation of the merger could be lower than the market price on the date of the merger agreement or the current market price. Macromedia stockholders should obtain recent market quotations of Adobe common stock before they vote on the merger.

Adobe and Macromedia may be required to comply with material restrictions or conditions in order to obtain the regulatory approvals required to consummate the merger.

The merger is subject to review by the Antitrust Division of the U.S. Department of Justice, or DOJ, under the HSR Act. Under this statute, Adobe and Macromedia are required to make pre-merger notification filings and to await the expiration or early termination of the statutory waiting period prior to consummating the merger. Adobe and Macromedia filed the required notification reports and on July 8, 2005, Adobe and Macromedia each received a government request for additional information and documentary material, or a second request. Both of the second requests were limited to information about the companies' products in the areas of web authoring/design and vector graphics illustration. The second requests will extend the waiting period imposed by the HSR Act until 30 days after Adobe and Macromedia have substantially complied with the requests. The merger may also be subject to review by the governmental authorities of various other jurisdictions. The governmental entities from whom approvals are required may attempt to condition their approval of the merger, or of the transfer to Adobe of licenses and other entitlements, on the satisfaction of certain regulatory conditions that may have the effect of imposing additional costs on Adobe or otherwise substantially

reducing the benefits to Adobe if the merger is consummated. Adobe and Macromedia have not yet obtained any of the regulatory approvals required to consummate the merger.

A shareholder derivative lawsuit has been filed against Adobe and its directors challenging the merger, and an unfavorable judgment or ruling in this lawsuit could prevent or delay the consummation of the merger, result in substantial costs or both.

On June 13, 2005, a shareholder derivative action entitled Steve Staehr, Derivatively on Behalf of Adobe Systems Incorporated v. Bruce R. Chizen, et. al., was filed in the Superior Court of the State of California for the County of Santa Clara against Adobe's directors and naming Adobe as a nominal defendant. The complaint alleges that the defendants breached their fiduciary duties of loyalty and due care and caused Adobe to waste corporate assets by failing to renegotiate or terminate the merger agreement following the announcement by Macromedia that it would restate its financial results for the fiscal years ended March 31, 1999 through 2004 and by failing to conduct sufficient due diligence prior to entering into the merger agreement. The complaint seeks, among other things, unspecified monetary damages, attorneys fees and certain forms of equitable relief, including preliminarily and permanently enjoining the consummation of the merger. Adobe has obligations under certain circumstances to hold harmless and indemnify each of the defendant directors against judgments, fines, settlements and expenses related to claims against such directors and otherwise to the fullest extent permitted under Delaware law and Adobe's bylaws and certificate of incorporation. Such obligations may apply to the lawsuit. Adobe's management believes that the allegations are without merit and intends to vigorously contest the action. However, there can be no assurance that the defendants will be successful in their defense. An unfavorable outcome in this lawsuit could prevent or delay the consummation of the merger, result in substantial costs to Adobe or both.

Risks Relating to Adobe

Adverse changes in general economic or political conditions in any of the major countries in which we do business could adversely affect our operating results.

If the economy worsens in any geographic areas where we do business, it would likely cause our future results to vary materially from our targets. A slower economy also may adversely affect our ability to grow. Political instability in any of the major countries in which we do business also may adversely affect our business.

Delays in development or shipment of new products or major new versions of existing products could cause a decline in our revenue.

Any delays or failures in developing and marketing our products, including upgrades of current products, may have a harmful impact on our results of operations. Our inability to extend our core technologies into new applications and new platforms and to anticipate or respond to technological changes could affect continued market acceptance of our products and our ability to develop new products. A portion of our future revenue will come from new applications. Delays in product or upgrade introductions could cause a decline in our revenue, earnings or stock price. We cannot determine the ultimate effect these delays or the introduction of new products or upgrades will have on our revenue or results of operations.

Introduction of new products by existing and new competitors, particularly Microsoft, could harm our competitive position and results of operations.

The end markets for our software products are intensely and increasingly competitive, and are significantly affected by product introductions and market activities of industry competitors. Microsoft has an electronic form tool called InfoPath included as part of its latest professional Office product

that competes with certain aspects of our Intelligent Documents product line. In addition, Microsoft is developing the next generation of its Windows operating system, codenamed Longhorn, and has announced it will add new electronic document capabilities to Longhorn, codenamed Metro, providing additional competition to our Intelligent Documents products and solutions. Certain aspects of Metro may also compete with our Adobe Postscript technologies and solutions. Given Microsoft's market dominance, InfoPath, Metro or any new competitive Microsoft product or technology that is bundled as part of its Office product or operating system, could harm our overall Intelligent Documents market opportunity. Also, some enterprise vendors provide intelligent document capabilities that could directly or indirectly compete with our Intelligent Documents products. Additionally, content creation/management tools that use other formats for electronic document distribution provide alternate solutions to customers, and indirectly compete with Adobe's Intelligent Documents products and the use of Adobe PDF. We also are seeing an increase in competition from clone PDF products marketed by other companies. Other competitors, including Microsoft, Apple, Avid and Google, may increase their presence in the digital imaging and digital video markets. Microsoft recently released a test version of a new professional graphics tool, codenamed Acrylic, which may compete with Adobe Photoshop and Adobe Illustrator. We also face competition from certain Open Source products. Additionally, many digital camera manufacturers are bundling their own or our competitors' digital imaging and video software products with their digital camera products. If these competing products achieve widespread acceptance, our operating results could suffer. In addition, consolidation has occurred among some of the competitors in our markets. Any further consolidations among our competitors may result in stronger competitors and may therefore harm our results of operations.

If we fail to successfully manage transitions to new business models or markets, our results of operations could be negatively impacted.

We are devoting significant resources to the development of technologies and service offerings to address demands in the marketplace for document generation, document process management, document collaboration and document control and security. As a result, we are transitioning to new business models and seeking to broaden our customer base in the enterprise and government markets, requiring a considerable investment of technical, financial and sales resources, and a scaleable organization. Many of our competitors may have advantages over us due to their larger presence, larger developer network, deeper experience in the enterprise and government markets and greater sales and marketing resources. It is our intent to form strategic alliances with leading enterprise and government solutions and service providers to provide additional resources to further enable penetration of the enterprise and government markets. If we are unable to successfully enter into strategic alliances, or if they are not as productive as we anticipate, our market penetration may not proceed as rapidly as we anticipate and our results of operations could be negatively impacted.

Our limited operating history with Adobe Creative Suite products makes it difficult to predict the revenue effect of the Adobe Creative Suite product cycle and the individual products integrated within these products.

If we fail to anticipate and develop new products in response to changes in demand for application software, computers and printers, our business could be harmed.

We offer our application-based products primarily on Windows and Macintosh platforms and on some UNIX platforms. We generally offer our server-based products, but not desktop application products, on the Linux platform as well as the Windows and UNIX platforms. To the extent that there is a slowdown of customer purchases of personal computers on either the Windows or Macintosh platform or in general, or to the extent that significant demand arises for our products or competitive products on the Linux desktop platform before we choose and are able to offer our products on this platform, our business could be harmed.

We may incur substantial costs enforcing our intellectual property rights and defending against third-party claims as a result of litigation or other proceedings.

In connection with the enforcement of our own intellectual property rights or in connection with disputes relating to the validity or alleged infringement of third-party rights, including patent rights, we have been, are currently and may in the future be subject to claims, negotiations or complex, protracted litigation. Intellectual property disputes and litigation are typically very costly and can be disruptive to our business operations by diverting the attention and energies of management and key technical personnel. Although we have successfully defended or resolved past litigation and disputes, we may not prevail in any ongoing or future litigation and disputes. Adverse decisions in such litigation or disputes could have negative results, including subjecting us to significant liabilities, requiring us to seek licenses from others, preventing us from manufacturing or licensing certain of our products or causing severe disruptions to our operations or the markets in which we compete, any one of which could seriously harm our business.

Additionally, although we actively pursue software pirates as part of our enforcement of our intellectual property rights, we do lose revenue due to illegal use of our software. If piracy activities increase, it may further harm our business.

We may not realize the anticipated benefits of past or future acquisitions, and integration of acquisitions may disrupt our business and management.

We have in the past and may in the future acquire additional companies, products or technologies. We may not realize the anticipated benefits of any acquisition, including the merger with Macromedia, and each acquisition has numerous risks. These risks include:

•: difficulty in assimilating the operations and personnel of the acquired company;
•: difficulty in effectively integrating the acquired technologies or products with our current products and technologies;
•: difficulty in maintaining controls, procedures and policies during the transition and integration;
•: disruption of our ongoing business and distraction of our management and employees from other opportunities and challenges due to integration issues;
•: inability to retain key technical and managerial personnel of the acquired business;
•: inability to retain key customers, distributors, vendors and other business partners of the acquired business;
•: inability to achieve the financial and strategic goals for the acquired and combined businesses;
•: incurring acquisition-related costs or amortization costs for acquired intangible assets that could impact our operating results;
•: potential impairment of our relationships with employees, customers, partners, distributors or third-party providers of technology or products;
•: potential failure of the due diligence processes to identify significant issues with product quality, architecture and development, or legal and financial contingencies, among other things;
•: incurring significant exit charges if products acquired in business combinations are unsuccessful; and
•: potential inability to assert that internal controls over financial reporting are effective.

Mergers and acquisitions of high technology companies are inherently risky, and ultimately, if we do not complete the integration of acquired businesses successfully and in a timely manner, we may not

realize the anticipated benefits of the acquisitions to the extent anticipated, which could adversely affect our business, financial condition or results of operations.

We rely on distributors to sell our products and any adverse change in our relationship with our distributors could result in a loss of revenue and harm our business.

We distribute our application products primarily through distributors, resellers, retailers and increasingly systems integrators, ISVs and VARs, collectively referred to as "distributors." A significant amount of our revenue for application products is from two distributors, Ingram Micro, Inc. and Tech Data Corporation. In addition, our channel program focuses our efforts on larger distributors, which has resulted in our dependence on a relatively small number of distributors licensing a large amount of our products. Our distributors also sell our competitors' products, and if they favor our competitors' products for any reason, they may fail to market our products as effectively or to devote resources necessary to provide effective sales, which would cause our results to suffer. In addition, the financial health of these distributors and our continuing relationships with them are important to our success. Some of these distributors may be unable to withstand adverse changes in business conditions. Our business could be seriously harmed if the financial condition of some of these distributors substantially weakens.

If our internal computer network and applications suffer disruptions or fail to operate as designed, our operations will be disrupted and our business may be harmed.

We rely on our network infrastructure and enterprise applications, internal technology systems and our website for our development, marketing, operational, support and sales activities. The hardware and software systems related to such activities are subject to damage from earthquakes, floods, fires, power loss, telecommunication failures and other similar events. They are also subject to computer viruses, physical or electronic vandalism or other similar disruptions that also could cause system interruptions, delays in our product development and loss of critical data and could prevent us from fulfilling our customers' orders. We have developed disaster recovery plans and backup systems to reduce the potentially adverse effect of such events, as they could impact our sales and damage our reputation and the reputation of our products. Any event that causes failures or interruption in our hardware or software systems could result in disruption in our business operations, loss of revenues or damage to our reputation.

We rely on turnkey assemblers and any adverse change in our relationship with our turnkey assemblers could result in a loss of revenue and harm our business.

We currently rely on six turnkey assemblers of our products, with at least two turnkeys located in each major region we serve. If any significant turnkey assembler terminates its relationship with us, or if our supply from any significant turnkey assembler is interrupted or terminated for any other reason, we may not have enough time or be able to replace the supply of products replicated by that turnkey assembler to avoid serious harm to our business.

Our future operating results are difficult to predict and are likely to fluctuate substantially from quarter to quarter and as a result the market price of our common stock may be volatile and our stock price could decline.

As a result of a variety of factors discussed in this joint proxy statement/prospectus, our quarterly revenues and operating results for a particular period are difficult to predict. Our revenues may grow at a slower rate than experienced in previous periods and, in particular periods, may decline. Additionally, we periodically provide operating model targets for revenue, gross margin, operating expenses, operating margin, other income, tax rate, share count and earnings per share. These targets reflect a number of assumptions, including assumptions about product pricing and demand, economic

and seasonal trends, manufacturing costs and volumes, the mix of shrink-wrap and licensing revenue, full and upgrade products, distribution channels and geographic markets. If one or more of these assumptions prove incorrect, our actual results may vary materially from those anticipated, estimated or projected.

Due to the factors noted above, our future earnings and stock price may be subject to volatility, particularly on a quarterly basis. Shortfalls in revenue or earnings or delays in the release of products or upgrades compared to analysts' or investors' expectations have caused and could cause in the future an immediate and significant decline in the trading price of our common stock. Additionally, we may not learn of such shortfalls or delays until late in the fiscal quarter, which could result in an even more immediate and greater decline in the trading price of our common stock. Finally, we participate in a highly dynamic industry. In addition to factors specific to us, changes in analysts' earnings estimates for us or our industry, and factors affecting the corporate environment, our industry or the securities markets in general, have resulted, and may in the future result, in volatility of our common stock price.

We are subject to risks associated with international operations which may harm our business.

We typically generate over 50% of our total revenue from sales to customers outside of the Americas. Sales to these customers subject us to a number of risks, including the following:

•: foreign currency fluctuations;
•: changes in government preferences for software procurement;
•: international economic and political conditions;
•: unexpected changes in, or impositions of, international legislative or regulatory requirements;
•: inadequate local infrastructure;
•: delays resulting from difficulty in obtaining export licenses for certain technology, tariffs, quotas and other trade barriers and restrictions;
•: transportation delays;
•: the burdens of complying with a variety of foreign laws; and
•: other factors beyond our control, including terrorism, war, natural disasters and diseases.

If sales to any of our customers outside of the Americas are delayed or cancelled because of any of the above factors, our revenue may be negatively impacted.

We may incur losses associated with currency fluctuations and may not be able to effectively hedge our exposure.

Our operating results are subject to fluctuations in foreign currency exchange rates. We attempt to mitigate a portion of these risks through foreign currency hedging, based on our judgment of the appropriate trade-offs among risk, opportunity and expense. We have established a hedging program to partially hedge our exposure to foreign currency exchange rate fluctuations, primarily the Japanese yen and the euro. We regularly review our hedging program and will make adjustments based on our judgment. Our hedging activities may not offset more than a portion of the adverse financial impact resulting from unfavorable movement in foreign currency exchange rates.

We have authorized the use of a substantial amount of our cash for the repurchase of our shares following consummation of the merger, and this use of funds may limit our ability to complete other transactions and may not be the most advantageous use for these funds.

As announced by Adobe on April 18, 2005, Adobe's board of directors has approved the use of up to $1 billion for the repurchase, on a discretionary basis, of Adobe stock. These repurchases will be in addition to Adobe's existing stock repurchase programs and are expected to commence following the consummation of the merger. We expect to repurchase shares, as business conditions warrant, for cash in open market transactions at prevailing market prices or through structured repurchase transactions. We expect to use a significant portion of the cash that is expected to be held by the combined company upon the consummation of the merger. This use of cash could limit our future flexibility to complete acquisitions of businesses or technology or other transactions, or make investments in research and development or other aspects of our operations, that might be in our best interests.

Changes in, or interpretations of, accounting principles, such as expensing of stock options, could result in unfavorable accounting charges.

We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles. These principles are subject to interpretation by the SEC and various bodies formed to interpret and create appropriate accounting principles. A change in these principles can have a significant effect on our reported results and may even retroactively affect previously reported transactions. Our accounting principles that recently have been or may be affected by changes in accounting principles include the following:

•: software revenue recognition;
•: accounting for share-based payments;
•: accounting for income taxes; and
•: accounting for business combinations and related goodwill.

In particular, the Financial Accounting Standards Board, or FASB, recently issued Statement of Financial Accounting Standards 123—revised 2004, or SFAS 123R, "Share-Based Payment," which requires the measurement of all share-based payments to employees, including grants of employee stock options, using a fair-value-based method and the recording of such expense in our consolidated statements of income. The accounting provisions of SFAS 123R are effective for annual periods beginning after June 15, 2005. We are required to adopt SFAS 123R in the first quarter of fiscal year 2006. We believe that the adoption of SFAS 123R will have a significant adverse effect on our reported financial results and may impact the way in which we conduct our business.

Changes in, or interpretations of, tax rules and regulations may adversely affect our effective tax rates.

Unanticipated changes in our tax rates could affect our future results of operations. Our future effective tax rates could be unfavorably affected by changes in tax laws or the interpretation of tax laws, by unanticipated decreases in the amount of revenue or earnings in countries with low statutory tax rates or by changes in the valuation of our deferred tax assets and liabilities.

In addition, we are subject to the continual examination of our income tax returns by the Internal Revenue Service and other domestic and foreign tax authorities. We regularly assess the likelihood of outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Any adverse outcome from these continual examinations may have an adverse effect on our operating results and financial position.

If we are unable to recruit and retain skilled personnel our business may be harmed.

Much of our future success depends on the continued service and availability of skilled personnel. Experienced personnel in the information technology industry are in high demand and competition for their talents is intense, especially in the Silicon Valley, where the majority of our employees are located. We have relied on our ability to grant equity compensation as one mechanism for recruiting and retaining such highly skilled personnel. Recently enacted accounting regulations requiring the expensing of equity compensation may impair our ability to provide these incentives without incurring significant compensation costs. If we are unable to continue to successfully attract and retain key personnel, our business may be harmed.

We may suffer losses from our equity investments which could harm our business.

We hold equity investments in public companies that have experienced significant declines in market value. We also have investments and may continue to make future investments in privately held companies, many of which are considered in the start-up or development stages. These investments are inherently risky, as the market for the technologies or products these companies have under development is typically in the early stages and may never materialize. Our investment activities can impact our net income. Future price fluctuations in these securities and any significant long-term declines in value of any of our investments could reduce our net income in future periods. We are uncertain about future investment gains and losses, as they are primarily dependent upon the operations of the underlying investee companies.

Risks Relating to Macromedia

Macromedia is subject to a number of risks similar to those described above under the following sub-headings:

•: Adverse changes in general economic or political conditions in any of the major countries in which we do business could adversely affect our operating results;
•: We rely on distributors to sell our products and any adverse change in our relationship with our distributors could result in a loss of revenue and harm our business;
•: If our internal computer network and applications suffer disruptions or fail to operate as designed, our operations will be disrupted and our business may be harmed;
•: Our future operating results are difficult to predict and are likely to fluctuate substantially from quarter to quarter and as a result the market price of our common stock may be volatile and our stock price could decline;
•: We are subject to risks associated with international operations which may harm our business;
•: We may incur losses associated with currency fluctuations and may not be able to effectively hedge our exposure;
•: Changes in, or interpretations of, accounting principles, such as expensing of stock options, could result in unfavorable accounting charges; and
•: If we are unable to recruit and retain skilled personnel our business may be harmed.

In addition, Macromedia is subject to a number of additional risks, including those described below.

Failure to complete the merger with Adobe could materially and adversely affect our results of operations and our stock price.

Consummation of the merger is subject to customary closing conditions, regulatory approvals, including antitrust approvals, and approval by the stockholders of Adobe and Macromedia, respectively. We cannot assure you that these conditions will be met or waived, that the necessary approvals will be obtained, or that we will be able to successfully consummate the merger as currently contemplated under the merger agreement or at all. If the merger is not consummated:

•: We may not realize any or all of the potential benefits of the merger, including any synergies that could result from combining the financial and proprietary resources of Macromedia and Adobe;
•: We will remain liable for significant transaction costs, including legal, accounting, financial advisory and other costs relating to the merger;
•: Under some circumstances, we may have to pay a termination fee to Adobe in the amount of $103.2 million;
•: The attention of our management and our employees may be diverted from day-to-day operations;
•: Our customers may seek to modify or terminate existing agreements, or prospective customers may delay entering into new agreements or purchasing our products as a result of the announcement of the merger; and
•: Our ability to attract new employees and retain our existing employees may be harmed by uncertainties associated with the merger.

The occurrence of any of these events individually or in combination could have a material adverse affect on our results of operations and our stock price.

If our product and version releases are not successful, our results of operations could be materially and adversely affected.

A substantial portion of our revenues is derived from license sales of new software products and new versions of existing software products. For example, in the second quarter of fiscal year 2006, Macromedia expects to introduce its MX 2005 product line. The success of new products and new versions of existing products depends on the timing, market acceptance and performance of new products or new versions of existing products. In the past we have experienced delays in the development of new products and enhancement of existing products and such delays may occur in the future. If we are unable, due to resource constraints or technological reasons, to develop and introduce products in a timely manner, our results of operations could be materially and adversely affected, including, in particular, our quarterly results. In addition, market acceptance of our new product or version releases will be dependent on our ability to include functionality and usability in such releases that address the requirements of customer demographics with which we may have limited prior experience. We must continue to update our existing products and services to keep them current with changing technology, competitive offerings and consumer preferences and must continue to develop new products and services to take advantage of new technologies that could otherwise render our existing products, or existing versions of such products, obsolete. Furthermore, our new product or version releases may contain undetected errors or "bugs," which may result in product failures or security breaches or otherwise fail to perform in accordance with customer expectations. In addition, such releases may not effectively guard against harmful or disruptive codes, including "virus" codes, new versions of which appear periodically, which may target files or programs created using our products. The occurrence of errors or harmful codes could result in loss of market share, diversion of

development resources, injury to our reputation and the reputation of our products or damage to our efforts to build positive brand awareness, any of which could have a material adverse effect on our business, operating results and financial condition. If we do not ship new products or new versions of our existing products as planned, if new product or version releases do not achieve adequate market acceptance, if new products or version releases fail to perform properly, or if we are unsuccessful in penetrating our business user market, which is comprised of non-technical business users that communicate, create and deliver information over the Internet into the market place, and our consumer market, which is comprised of device manufacturers, telecommunications carriers and news and entertainment networks who embed our technology on their platforms, our results of operations could be materially and adversely affected.

We face intense competition.

We operate in a highly competitive market characterized by market and customer expectations to incorporate new features and to accelerate the release of new products. These market factors represent both opportunities and competitive threats to us. With respect to competitive threats:

•: Our designer and developer tools compete directly and indirectly with products from vendors including Microsoft Corporation, or Microsoft, International Business Machines Corporation, or IBM, and other companies.
•: Our server software products compete in a highly competitive and rapidly changing market for application server technologies. With respect to these products, we compete directly with products offered by Microsoft, IBM, BEA Systems, Inc., Sun Microsystems, Inc. and various other open-source or free technologies.
•: Our products marketed to business users, such as Breeze and Contribute, compete directly and indirectly with products offered by IBM, Microsoft, WebEx Communications, Inc. and other companies.
•: Our products offered to mobile operators and device manufacturers for use in consumer devices compete directly and indirectly with various technologies and products from both established and emerging vendors.

Introduction of new products, or introduction of new functionality in current products, by us or by other companies may intensify our current competitive pressures. Some of our current and potential competitors have greater financial, marketing, technical and intellectual property resources than we do.

Furthermore, we have a number of strategic alliances with large and complex organizations, some of which may compete with us in certain markets. These arrangements are generally limited to specific projects, the goal of which is generally to achieve product compatibility, promote product adoption or facilitate product distribution. If successful, these relationships may be mutually beneficial. However, these alliances carry an element of risk because, in most cases, we must compete in some business areas with a company with which we also have a strategic alliance and, at the same time, cooperate with that company in other business areas. If these companies fail to perform or if these relationships fail to materialize as expected, we could suffer delays in product development, encounter barriers to product adoption and distribution or fail to realize the anticipated economic benefit of the strategic alliance.

Revenues from our consumer market may be difficult to predict.

Our future revenue growth is increasingly dependent upon our ability to continue to increase net revenues obtained from licensing our consumer products for use in mobile phones, set-top boxes, game devices, personal digital assistants, or PDAs, hand-held computers and other consumer electronic devices. We have a limited history of licensing products in our consumer market and believe these

transactions present considerably greater risks than we have historically experienced with sales of products licensed to designers and developers. Specific risks related to our ability to predict revenues in our consumer market include the following:

•: Sales cycles are long and complex as customers typically consider a number of factors before agreeing to license our technology, including, among other things, the time and cost to embed our technology into their devices. As a result, it may be difficult to predict when and if license arrangements will become effective.
•: Because our technology is integrated into devices offered by our customers, we could be adversely impacted if our products are not successfully integrated with those of the customer or if their products are not successfully marketed or sold to consumers.
•: We may be required to defer revenue recognition for our consumer license arrangements for a significant period of time after initially entering into such license agreements for a variety of reasons, including, but not limited to, instances where there are certain acceptance criteria and/or integration services necessary to determine whether our technology functions properly with the product offerings of the customer.
•: Many of our licensing arrangements require licensees to pay per-unit royalties, requiring us to rely on the accuracy and timeliness of licensee royalty reports generated by our customers in recognizing royalty revenues.
•: Consumer markets are extremely competitive and are influenced by rapidly changing industry standards and consumer preferences. Changes in such standards or preferences could have a significant impact on demand for specific technologies, including our technology.

We may not be able to successfully defend or enforce our intellectual property rights.

Because we are a software company, our business is dependent on our ability to protect our intellectual property rights. We rely on a combination of patent, copyright, trade secret and trademark laws, as well as employee and third-party nondisclosure agreements and license agreements, to protect our intellectual property rights and products. Policing unauthorized use of products and fully protecting our proprietary rights are difficult and we cannot guarantee that the steps we have taken to protect our proprietary rights will be successful. In addition, effective patent, copyright, trade secret and trademark protection may not be available in every country in which our products are distributed or used. In particular, while we are unable to determine the exact extent of piracy of our software products, software piracy may depress our revenues. While this would also adversely affect domestic revenue, revenue loss from piracy of our software products is believed to be even more significant outside of the United States, particularly in countries where laws provide less protection of intellectual property rights. Protection of our intellectual property rights also is difficult in situations where we have taken certain actions to promote broader adoption of our technology. For instance, in an effort to promote broader adoption of our technology, in particular the Macromedia Flash Player and the Macromedia Shockwave Player, we publish and grant industry standard-setting organizations, user groups and third parties the right to use certain Macromedia product specifications, file formats, application programming interfaces, or APIs, and other information. These specifications, file formats, APIs and other information could be used to produce products that compete with and reduce demand for Macromedia's own products. In addition, our intellectual property enforcement rights may be diminished because of our decision to publish or license certain intellectual property in an effort to promote its adoption.

Our failure to maintain an effective system of internal controls could harm our business.

Designing and maintaining effective internal controls over financial reporting is expensive and requires considerable attention from management, employees and expert outside advisors. Internal controls, however well-designed and operated, cannot provide any absolute assurance that the objectives of the controls will be met. Section 404 of the Sarbanes-Oxley Act of 2002 requires that we and our independent registered public accounting firm periodically certify the adequacy of our internal controls over financial reporting. This requirement first became applicable to us on March 31, 2005. As part of the Section 404 certification process that concluded after March 31, 2005, we identified a material weakness in our internal controls over income taxes that had existed as of March 31, 2005. This deficiency, for which remediation has already begun, or any actual failure of our internal controls, could harm the financial position of our business, reduce investor confidence, cause a decline in the market price for our common stock, and subject us to costly litigation.

We face risks associated with acquisitions.

We have entered into business combinations with other companies in the past, including our acquisition of eHelp in December 2003 and two acquisitions in the fourth quarter of fiscal year 2003, and we are permitted under the terms of the merger agreement to make additional acquisitions prior to the consummation of the merger under limited circumstances. Acquisitions generally involve significant risks, including, among other things, difficulties in the assimilation of the operations, business strategy, services, technologies and corporate culture of the acquired companies, diversion of management's attention from other business concerns, overvaluation of the acquired companies and the acceptance of the acquired companies' products and services by our customers. In addition, future acquisitions would likely result in dilution to existing stockholders, if stock or stock options are issued, or if we assume debt and contingent liabilities, which could have a material adverse effect on our financial condition, results of operations and liquidity. Accordingly, any future acquisitions could result in a material adverse effect on our results of operations.

Changing our pricing and business model could adversely affect our business.

We periodically make changes to our product pricing or offer alternative methods of licensing our product, based on market conditions or customer demands, or in connection with marketing activities. Such increases in the pricing of our products may cause our customers to seek lower-priced alternatives, decrease the aggregate demand for such products and have an adverse effect on our results of operations. In addition, competition in the various markets in which we operate may require us to reduce prices on certain products in such markets. In the event that we are required to reduce the pricing of our products, we may not be able to offset the lower unit price with increased demand for the corresponding products. Furthermore, any changes in pricing of products in general may result in delays in transactions as our customers and our sales force adapt to such price changes and may have an adverse effect on our results of operations. Moreover, customer demand and competition in the market may require us to offer alternative methods of licensing our products. In the event that we offer alternative methods of licensing our products, the revenues generated from licenses based on such alternative methods may not offset the loss of revenues from our existing method of licensing our products in any given period and may have an adverse effect on our results of operations.

Product returns could exceed our estimates and harm our net revenues.

The primary sales channels into which we sell our products throughout the world are a network of distributors and VARs. Agreements with our distributors and VARs contain specific product return privileges for stock rotation and obsolete products that are generally limited to contractual amounts. In general, we expect sales returns to increase following the announcement of new or upgraded versions of our products or in anticipation of such product announcements, as our distributors and resellers seek

to reduce their inventory levels of the prior version of a product in advance of receiving the new version. Similarly, we expect that product inventory held by our distributors and resellers would increase following the successful introduction of new or upgraded products, as these resellers stock the new version in anticipation of end-user demand, which would result in a decrease in our allowance for sales returns of our products. As part of our revenue recognition practices, we have established a reserve for estimated sales returns. The reserve is based on a number of factors, including channel inventory levels and the timing of new product introductions. Actual product returns in excess of our reserve estimates would have an adverse effect on our net revenues and our results of operations.

Changes in tax laws and regulations may increase our expenses and the cost of our products.

In October 1998, the federal Internet Tax Freedom Act, or ITFA, was enacted. The ITFA imposed a three-year moratorium on state and local taxes related to Internet access and discriminatory taxes on electronic commerce that expired on October 20, 2001. The moratorium was extended in November 2001 and in November 2003. Under the current law, the moratorium is set to expire on November 1, 2007. The Senate introduced a bill (S. 849) on April 19, 2005 to make the moratorium permanent. The bill has been referred to the Committee on Commerce, Science and Transportation. If the ITFA is not extended or permanently enacted, state and local jurisdictions may seek to impose taxes on Internet access or electronic commerce within their jurisdictions. These taxes could increase our operating expenses and the sales price of our products.

Also, on July 1, 2003, the European Union enacted legislation requiring all non-European Union vendors to collect Value Added Tax, or VAT, on all electronically supplied goods or services sold to consumers in the European Union. Compliance with this new European Union tax legislation has increased the cost of our products to consumers in the European Union and could decrease the demand for our products in that region.

Changes or disruptions in services provided by third parties could disrupt our business.

We rely primarily on a single independent third party to produce and distribute our box products and on a second independent third party to fulfill volume licenses. If there is a temporary or permanent disruption of our supply from such manufacturers, we may not be able to replace the supply in sufficient time to meet the demand for our products. Any such failure to meet the demand for our products would adversely affect our revenues and might cause some users to purchase licenses to our competitors' products to meet their requirements.

We rely on a limited number of independent third parties to provide support services to our customers. If any of these third-party service providers terminates its relationship with us or ceases to be able to continue to maintain such relationship with us, we may not have sufficient notice or time to avoid serious disruption to our business. Furthermore, if any such third-party service providers fail to provide adequate or satisfactory support for our products, our reputation as well as the success of our products may be adversely affected.

Moreover, we have outsourced, and may continue to outsource, specific development and quality assurance activities for certain of our products. If such third-party developers are not able to complete the development activities on time, the release of the corresponding new product or a new version may be delayed. In addition, since we are unable to control the development activities outsourced by us to third parties, the portions of our product developed by such third parties may contain significant errors or "bugs."

Termination of licenses for technologies from third parties could cause delays, increased costs or reduced functionality that may result in a material reduction in our net revenues and higher costs.

We license and distribute third-party technologies that are bundled with or embedded in our products. If any of these licenses from third parties were terminated or were not renewed, or the third-party technology was to become subject to an intellectual property dispute, we might not be able to ship our products in which these technologies are bundled or embedded. We would then have to seek an alternative to such third party technology to the extent that such an alternative exists. This could result in delays in releasing and/or shipping our products, increased costs or reduced functionality of our products and material reduction in our net revenues.

Adverse economic conditions in the commercial real estate market may affect our ability to sublease vacated portions of properties held under sublease.

Our restructuring expenses and accruals related to our excess leased properties involve significant estimates made by management using the best information available at the time that the estimates were made, including market data obtained from real estate brokers in the local markets. These estimates include evaluating the timing and market conditions of rental payments and sublease income. Changes in our current operations could result in our vacating additional portions of properties held under operating leases prior to the expiration of the corresponding lease agreements and could result in additional changes. The general adverse economic conditions in the areas where we have significant leased properties have resulted in a surplus of business facilities making it difficult to sublease properties. There can be no assurance that market conditions will improve during the terms of the lease periods. If market conditions deteriorate, we may be unable to sublease our excess leased properties at all or on terms acceptable to us, or we may not meet our expected estimated levels of sublease income and our results of operations could be adversely affected.

Future impairment assessments on certain intangible assets may result in additional impairment charges.

In fiscal year 2003, we adopted SFAS No. 142, Goodwill and Other Intangible Assets. As a result, our goodwill and other intangible assets that have an indefinite useful life are no longer amortized, but instead, reviewed at least annually for impairment. Significant changes in demand for our products or changes in market conditions in the principal markets in which we sell our products, could adversely impact the carrying value of these intangible assets. In particular, if there is (i) a significant and other than temporary decline in the market value of our common stock; (ii) a decrease in the market value of a particular asset of ours; or (iii) operating or cash flow losses combined with forecasted future losses, we could be required to record impairment charges related to goodwill and other intangible assets, which could adversely affect our financial results. In addition, should we develop and manage our business using discrete financial information for reporting units in the future, we may be required to allocate our goodwill balance to those reporting units, which may result in an impairment of part or all of our recorded goodwill.

THE ADOBE SPECIAL MEETING

Date, Time and Place

The special meeting of Adobe stockholders will be held on Wednesday, August 24, 2005, at the principal executive offices of Adobe located at 345 Park Avenue, San Jose, California commencing at 3:00 p.m. local time. We are sending this joint proxy statement/prospectus to you in connection with the solicitation of proxies by the Adobe board of directors for use at the Adobe special meeting and any adjournments or postponements of the special meeting.

Purposes of the Adobe Special Meeting

The purposes of the Adobe special meeting are:

•: to consider and vote on Proposal No. 1 to approve the issuance of shares of Adobe common stock in the merger;
•: to consider and vote on Proposal No. 2 to adjourn the special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1; and
•: to transact such other business as may properly come before the special meeting or any adjournments or postponements of the special meeting.

Recommendation of Adobe's Board of Directors

ADOBE'S BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED AND BELIEVES THAT THE ISSUANCE OF SHARES OF ADOBE COMMON STOCK IN THE MERGER IS ADVISABLE TO, AND IN THE BEST INTERESTS OF, ADOBE AND ITS STOCKHOLDERS AND HAS UNANIMOUSLY APPROVED SUCH ISSUANCE. ADOBE'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ADOBE STOCKHOLDERS VOTE "FOR" PROPOSAL NO. 1 TO APPROVE THE ISSUANCE OF SHARES OF ADOBE COMMON STOCK IN THE MERGER.

ADOBE'S BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED AND BELIEVES THAT THE PROPOSAL TO ADJOURN THE ADOBE SPECIAL MEETING, IF NECESSARY, IF A QUORUM IS PRESENT, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES IN FAVOR OF PROPOSAL NO. 1 IS ADVISABLE TO, AND IN THE BEST INTERESTS OF, ADOBE AND ITS STOCKHOLDERS AND HAS UNANIMOUSLY APPROVED AND ADOPTED THE PROPOSAL. ACCORDINGLY, ADOBE'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ALL ADOBE STOCKHOLDERS VOTE "FOR" PROPOSAL NO. 2 TO ADJOURN THE ADOBE SPECIAL MEETING, IF NECESSARY, IF A QUORUM IS PRESENT, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES IN FAVOR OF PROPOSAL NO. 1.

Record Date and Voting Power

Only holders of record of Adobe common stock at the close of business on the record date, July 19, 2005, are entitled to notice of, and to vote at, the Adobe special meeting. There were approximately 1,668 holders of record of Adobe common stock at the close of business on the record date. Because many of such shares are held by brokers and other institutions on behalf of stockholders, Adobe is unable to estimate the total number of stockholders represented by these record holders. There were 492,276,674 shares of Adobe common stock issued and outstanding at the close of business on the record date. Each share of Adobe common stock entitles the holder thereof to one vote on each matter submitted for stockholder approval. See "Security Ownership by Certain Beneficial Owners" for

information regarding persons known to the management of Adobe to be the beneficial owners of more than 5% of the outstanding shares of Adobe common stock.

Voting and Revocation of Proxies

The proxy accompanying this joint proxy statement/prospectus is solicited on behalf of the board of directors of Adobe for use at the Adobe special meeting.

All properly executed proxies that are not revoked will be voted at the Adobe special meeting and at any adjournments or postponements of the special meeting in accordance with the instructions contained in the proxy. If a holder of Adobe common stock executes and returns a proxy and does not specify otherwise, the shares represented by that proxy will be voted "FOR" Proposal No. 1 to approve the issuance of shares of Adobe common stock in the merger and "FOR" Proposal No. 2 to adjourn the special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1, in accordance with the recommendation of the Adobe board of directors.

An Adobe stockholder who has submitted a proxy may revoke it at any time before it is voted at the Adobe special meeting by executing and returning a proxy bearing a later date, providing proxy instructions via the telephone or the Internet (your latest telephone or Internet proxy is counted), filing written notice of revocation with the Secretary of Adobe stating that the proxy is revoked or attending the special meeting and voting in person.

Required Vote

The presence, in person or by proxy, at the special meeting of the holders of a majority of the shares of Adobe common stock outstanding and entitled to vote at the special meeting is necessary to constitute a quorum at the meeting. Approval of each of Proposal No. 1 and Proposal No. 2 requires the affirmative vote of the holders of a majority of the votes cast in person or by proxy at the special meeting. Abstentions and broker non-votes will be counted towards a quorum, but will not be counted for any purpose in determining whether either proposal is approved.

As of the record date for the special meeting, the directors and executive officers of Adobe owned approximately 0.7% of the outstanding shares of Adobe common stock entitled to vote at the meeting. Bruce R. Chizen, an executive officer and director of Adobe, and Murray J. Demo and Shantanu Narayen, executive officers of Adobe, have each entered into a voting agreement with Macromedia, dated April 17, 2005. They have agreed in the voting agreements to vote all shares of Adobe common stock owned by them as of the record date in favor of the issuance of shares of Adobe common stock in the merger. They also granted Macromedia irrevocable proxies to vote their shares of Adobe common stock in favor of the issuance of shares of Adobe common stock in the merger. Approximately 403,746 shares of Adobe common stock, which represent approximately 0.1% of the outstanding shares of Adobe common stock as of the record date, are subject to the voting agreements and irrevocable proxies. For more information regarding the voting agreements, see the section entitled "Voting Agreements."

Solicitation of Proxies

In addition to solicitation by mail, the directors, officers, employees and agents of Adobe may solicit proxies from Adobe's stockholders by personal interview, telephone, telegram or otherwise. Adobe will bear the costs of the solicitation of proxies from its stockholders, except that Adobe and Macromedia will each pay one-half of the cost of printing this joint proxy statement/prospectus. Arrangements will also be made with brokerage firms and other custodians, nominees and fiduciaries who are record holders of Adobe common stock for the forwarding of solicitation materials to the beneficial owners of Adobe common stock. Adobe will reimburse these brokers, custodians, nominees

and fiduciaries for the reasonable out-of-pocket expenses they incur in connection with the forwarding of solicitation materials. Adobe has engaged the services of Innisfree M&A Incorporated to distribute proxy solicitation materials to brokers, banks and other nominees and to assist in the solicitation of proxies from Adobe stockholders for a fee of approximately $20,000 plus reasonable out-of-pocket expenses.

Other Matters

As of the date of this joint proxy statement/prospectus, the Adobe board of directors does not know of any business to be presented at the Adobe special meeting other than as set forth in the notice accompanying this joint proxy statement/prospectus. If any other matters should properly come before the special meeting, it is intended that the shares represented by proxies will be voted with respect to such matters in accordance with the judgment of the persons voting the proxies.

THE MACROMEDIA SPECIAL MEETING

Date, Time and Place

The special meeting of Macromedia stockholders will be held on Wednesday, August 24, 2005, at the principal executive offices of Macromedia located at 601 Townsend Street, San Francisco, California 94103, commencing at 3:00 p.m. local time. We are sending this joint proxy statement/prospectus to you in connection with the solicitation of proxies by the Macromedia board of directors for use at the Macromedia special meeting and any adjournments or postponements of the special meeting.

Purposes of the Macromedia Special Meeting

The purposes of the Macromedia special meeting are:

•: to consider and vote upon Proposal No. 1 to adopt the merger agreement;
•: to consider and vote on Proposal No. 2 to adjourn the special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1; and
•: to transact such other business as may properly come before the special meeting or any adjournments or postponements of the special meeting.

Recommendations of Macromedia's Board of Directors

MACROMEDIA'S BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED AND BELIEVES THAT THE MERGER IS ADVISABLE AND FAIR TO, AND IN THE BEST INTERESTS OF, MACROMEDIA AND ITS STOCKHOLDERS AND HAS UNANIMOUSLY APPROVED THE MERGER AND THE MERGER AGREEMENT. MACROMEDIA'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT MACROMEDIA STOCKHOLDERS VOTE "FOR" PROPOSAL NO. 1 TO ADOPT THE MERGER AGREEMENT.

MACROMEDIA's BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED AND BELIEVES THAT THE PROPOSAL TO ADJOURN THE MACROMEDIA SPECIAL MEETING, IF NECESSARY, IF A QUORUM IS PRESENT, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES IN FAVOR OF THE FOREGOING PROPOSAL NO. 1 IS ADVISABLE TO, AND IN THE BEST INTERESTS OF, MACROMEDIA AND ITS STOCKHOLDERS AND HAS UNANIMOUSLY APPROVED AND ADOPTED THE PROPOSAL. ACCORDINGLY, MACROMEDIA'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT MACROMEDIA STOCKHOLDERS VOTE "FOR" PROPOSAL NO. 2 TO ADJOURN THE MACROMEDIA SPECIAL MEETING, IF NECESSARY, IF A QUORUM IS PRESENT, TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES IN FAVOR OF PROPOSAL NO. 1.

Record Date and Voting Power

Only holders of record of Macromedia common stock at the close of business on the record date, July 19, 2005, are entitled to notice of, and to vote at, the Macromedia special meeting. There were approximately 500 holders of record of Macromedia common stock at the close of business on the record date, with 75,913,164 shares of Macromedia common stock issued and outstanding. Because many of such shares are held by brokers and other institutions on behalf of stockholders, Macromedia is unable to estimate the total number of stockholders represented by these record holders. Each share of Macromedia common stock entitles the holder thereof to one vote on each matter submitted for stockholder approval. See "Security Ownership by Certain Beneficial Owners" for information regarding persons known to the management of Macromedia to be the beneficial owners of more than 5% of the outstanding shares of Macromedia common stock.

Voting and Revocation of Proxies

The proxy accompanying this joint proxy statement/prospectus is solicited on behalf of the board of directors of Macromedia for use at the Macromedia special meeting.

All properly executed proxies that are not revoked will be voted at the Macromedia special meeting and at any adjournments or postponements of the special meeting in accordance with the instructions contained in the proxy. If a holder of Macromedia common stock executes and returns a proxy and does not specify otherwise, the shares represented by the proxy will be voted "FOR" Proposal No. 1 to adopt the merger agreement and "FOR" Proposal No. 2 to adjourn the special meeting, if necessary, if a quorum is present, to solicit additional proxies if there are not sufficient votes in favor of Proposal No. 1, in accordance with the recommendation of the Macromedia board of directors.

A Macromedia stockholder who has submitted a proxy may revoke it at any time before it is voted at the Macromedia special meeting by executing and returning a proxy bearing a later date, providing proxy instructions via the telephone or the Internet (your latest telephone or Internet proxy is counted), filing written notice of revocation with the Secretary of Macromedia stating that the proxy is revoked or attending the special meeting and voting in person.

Required Vote

The presence, in person or by proxy, at the special meeting of the holders of a majority of the shares of Macromedia common stock outstanding and entitled to vote at the Macromedia special meeting is necessary to constitute a quorum at the Macromedia special meeting. Approval of Proposal No. 1 requires the affirmative vote of the holders of a majority of the voting power of the shares of Macromedia common stock outstanding on the record date of the Macromedia special meeting. Approval of Proposal No. 2 requires the affirmative vote of holders of a majority of the votes cast in person or by proxy at the Macromedia special meeting. Abstentions will be counted towards a quorum and will have the same effect as negative votes on Proposal No. 1, but will not be counted for any purpose in determining whether Proposal No. 2 is approved. Broker non-votes will be counted towards a quorum, but will not be counted for any purpose in determining whether either proposal is approved.

As of the record date for the Macromedia special meeting, the directors and executive officers of Macromedia owned approximately 4.1% of the outstanding shares of Macromedia common stock entitled to vote at the meeting. Robert K. Burgess, Stephen A. Elop and Elizabeth A. Nelson, each an executive officer and director of Macromedia, have each entered into a voting agreement with Adobe dated April 17, 2005.

ADOBE PROPOSAL NO. 1 AND MACROMEDIA PROPOSAL NO. 1

THE MERGER

General Description of the Merger

At the effective time, Merger Sub will be merged with and into Macromedia. Macromedia will be the surviving corporation and will continue as a wholly owned subsidiary of Adobe. In the merger, each share of Macromedia common stock outstanding at the effective time will automatically be converted into the right to receive 1.38 shares of Adobe common stock. Each Macromedia stockholder who would otherwise be entitled to receive a fraction of a share of Adobe common stock (after aggregating all fractional shares to be received by such stockholder) will instead be paid in cash for such fractional share.

Based on the number of shares of Adobe common stock and Macromedia common stock outstanding as of the record date, up to 104,760,166 shares of Adobe common stock will be issuable pursuant to the merger agreement, representing approximately 17.5% of the total Adobe common stock to be outstanding after such issuance. This assumes that no Macromedia or Adobe stock options are exercised after the record date and prior to the effective time of the merger.

Background

From time to time, Adobe has analyzed various potential acquisition candidates, including Macromedia.

From 2000 to July 2002, Adobe and Macromedia were involved in patent litigation. Following the settlement of this litigation, Bruce R. Chizen, Adobe's Chief Executive Officer, and Robert K. Burgess, Macromedia's Chairman of the Board and then-Chief Executive Officer, became better acquainted, speaking occasionally by telephone or in person.

In September 2004, Messrs. Burgess and Chizen discussed the possibility of a business combination involving the two companies.

On September 22, 2004, the Adobe board of directors held a meeting at which Mr. Chizen informed the board of his conversation with Mr. Burgess. The board determined that Adobe, in conjunction with its annual strategic planning process, should internally review whether a business combination with Macromedia would be strategic. Following that meeting, Mr. Chizen indicated to Mr. Burgess that Adobe was involved in internal strategic planning and would not be pursuing a business combination at that time.

On January 11, 2005, the Adobe board of directors held a meeting at which Adobe management made a presentation regarding the possible strategic fit between Macromedia and Adobe. The board requested further analysis and information and did not make any decision about pursuing a business combination with Macromedia.

On January 21, 2005, the Adobe board of directors held a meeting at which Adobe management presented to the board the further analysis and information that the board had requested at the January 11, 2005 board meeting. Following the presentation, the board approved initiating discussions with Macromedia regarding a potential business combination and working with Goldman Sachs, as Adobe's financial advisor, and Cooley Godward, as Adobe's outside legal counsel, regarding such a potential business combination. Following this meeting, on January 21, 2005, Mr. Chizen contacted

Mr. Burgess and expressed Adobe's interest in initiating discussions regarding a potential business combination with Macromedia.

On January 28, 2005, Mr. Chizen, Shantanu Narayen, Adobe's President and Chief Operating Officer, Murray J. Demo, Adobe's Senior Vice President and Chief Financial Officer, and Karen O. Cottle, Adobe's Senior Vice President and General Counsel, met with Mr. Burgess, who, on January 19, 2005, had resigned as Chief Executive Officer of Macromedia and assumed the role of Executive Chairman of Macromedia, Stephen A. Elop, Macromedia's then- and current Chief Executive Officer, Elizabeth A. Nelson, Macromedia's Executive Vice President and Chief Financial Officer, Kevin Lynch, Macromedia's Executive Vice President and Chief Software Architect, and Loren Hillberg, Macromedia's then-General Counsel, to better understand the respective businesses at a high level and the company cultures in order to decide whether to move forward with further discussions. Following the meeting, the parties determined to move forward with further discussions.

From January 28 to February 9, 2005, representatives of Adobe, Cooley Godward, Macromedia and Fenwick & West, Macromedia's outside legal counsel, held telephone conferences to negotiate the terms of a nondisclosure agreement and establish the procedures for preliminary financial due diligence. The nondisclosure agreement was executed on February 9, 2005. Neither the nondisclosure agreement nor any other agreement in effect between Adobe and Macromedia prior to the execution of the merger agreement contained any provision that prevented Macromedia from discussing potential business combinations with other parties.

On February 1 and February 7, 2005, Mr. Demo and representatives of Goldman Sachs met with Ms. Nelson and representatives of Morgan Stanley, Macromedia's financial advisor, and engaged in preliminary financial due diligence discussions regarding Macromedia's business.

On February 10, 2005, Messrs. Chizen, Narayen and Demo and Ms. Cottle, together with representatives of Goldman Sachs, met with Messrs. Burgess, Elop and Hillberg and Ms. Nelson, together with representatives of Morgan Stanley, and discussed Adobe's and Macromedia's respective businesses, strategies and financial position. They also discussed general strategic benefits of a potential business combination.

On February 11, 2005, Mr. Demo and two other finance employees from Adobe met with Ms. Nelson for further due diligence related to Macromedia's financial position.

On February 19, 2005, at a meeting of the Adobe board of directors, the directors discussed the potential business combination. Representatives of Cooley Godward reviewed with the board the board's fiduciary obligations, management reviewed with the board its views of the strategic rationale for the potential business combination and Goldman Sachs presented a financial analysis relating to the potential business combination. At that meeting, the board authorized Adobe to present a proposal to Macromedia for a potential business combination.

On February 20, 2005, Mr. Chizen had a telephone conversation with Mr. Burgess and communicated that a proposal would be forthcoming from Adobe's financial advisor, Goldman Sachs.

On February 22, 2005, Goldman Sachs orally delivered a proposal by Adobe regarding a potential business combination to Morgan Stanley.

On February 23, 2005, the Macromedia board of directors held a meeting at which Mr. Burgess reviewed with the board the status of the discussions with Adobe, including the proposal presented by Adobe. Macromedia management reviewed business and financial information regarding Adobe and strategic and operational considerations relating to the potential business combination. Representatives of Morgan Stanley reviewed with the board financial considerations relating to the potential business combination. The Macromedia board determined that the proposal made by Adobe was not sufficiently attractive to warrant further consideration. Mr. Burgess communicated the Macromedia board's

determination to Mr. Chizen that same day. Following such communication, both companies discontinued further work on the potential business combination.

On February 28, 2005, at a meeting of the Adobe board of directors, Mr. Chizen informed the board of Macromedia's rejection of the Adobe proposal and indicated that the potential business combination would no longer be moving forward.

On March 21, 2005, Messrs. Chizen and Burgess discussed whether to re-engage in discussions regarding the potential business combination.

At the March 22-23, 2005 Adobe board of directors meeting, Mr. Chizen informed the board of his discussion with Mr. Burgess and the Adobe board requested that Mr. Chizen re-engage in discussions with Mr. Burgess regarding the potential business combination.

On March 23, 2005, Mr. Chizen called Mr. Burgess to inform him that Adobe was interested in re-opening discussions with respect to a potential business combination.

On March 25, 2005, the Macromedia board of directors held a meeting at which Mr. Burgess provided the board with an update on recent discussions with Mr. Chizen regarding the potential business combination with Adobe. Representatives of Morgan Stanley discussed with the board various financial and strategic aspects of a potential business combination with Adobe. Representatives of Fenwick & West reviewed with the board the fiduciary duties of Macromedia's directors in connection with a potential business combination. The Macromedia board considered, with input from both its legal and financial advisors, possible strategic alternatives to a potential business combination with Adobe, including the possibility of remaining an independent entity and the possibility of contacting other parties regarding a business combination. The Macromedia board, with the advice of senior management of Macromedia and its legal and financial advisors, also considered and discussed various matters relating to the potential business combination with Adobe, including the strategic value of such a combination and potential synergies to be derived from such a combination and possible terms and valuations under which such a combination should be further pursued. At the conclusion of this meeting, the Macromedia board expressed support for continuing discussions regarding a potential business combination with Adobe.

On March 28, 2005, Messrs. Chizen, Narayen and Demo and representatives of Goldman Sachs and Cooley Godward met with Messrs. Burgess and Elop and Ms. Nelson and representatives of Morgan Stanley and Fenwick & West. At the meeting, the parties discussed Adobe's and Macromedia's respective businesses, strategies, competitive environments, financial results and prospects. They also discussed the potential strategic benefits and risks of a potential business combination. The parties expressed their views on key terms for a potential business combination. Following the meeting, in separate conversations, Mr. Chizen contacted Mr. Burgess and representatives of Goldman Sachs contacted representatives of Morgan Stanley to communicate a new proposal for the potential business combination.

On March 30, 2005, the Macromedia board of directors held a meeting at which Mr. Burgess provided an update on the March 28, 2005 discussions with representatives of Adobe, as well as the subsequent conversation Mr. Burgess had with Mr. Chizen, regarding the potential business combination. Representatives of Morgan Stanley updated the board with respect to its ongoing financial analysis regarding the potential business combination. The Macromedia board continued its discussion of the potential business combination, including the strategic rationale for such a business combination, as well as the relative potential benefits and risks of combining with Adobe compared to the benefits and risks of remaining an independent entity. At the conclusion of this meeting, the Macromedia board expressed support for continuing discussions regarding a potential business combination with Adobe.

On April 1, 2005, at a meeting of the Adobe board of directors, Mr. Chizen and a representative of Goldman Sachs provided the board with an update on the discussions with representatives of

Macromedia. Representatives of Goldman Sachs updated the board with respect to its ongoing financial analysis regarding the potential business combination. The Adobe board continued its discussion, with input from both its legal and financial advisors, of the potential business combination, including the strategic rationale for a business combination, as well as the potential benefits and risks of combining with Macromedia. At the conclusion of this meeting, the Adobe board authorized management to continue discussions regarding the potential business combination.

On April 2, 2005, the Macromedia board of directors met and discussed the potential business combination with Adobe. Messrs. Chizen, Narayen and Demo and John D. Brennan, Senior Vice President, Corporate Development of Adobe, provided to the Macromedia board an overview of Adobe's business and Adobe's strategic rationale for a business combination. The Macromedia board continued its discussion, with input from both its legal and financial advisors, of the potential business combination, including the strategic rationale for such a business combination, as well as the potential benefits and risks of combining with Adobe. Representatives of Fenwick & West further reviewed with the Macromedia board considerations involved in the potential business combination. At the conclusion of this meeting, the Macromedia board expressed support for continuing discussions regarding the potential business combination.

Between April 2 and April 17, 2005, Messrs. Chizen, Narayen, Demo and Brennan and other Adobe executives met numerous times with Messrs.

Between April 10 and April 17, 2005, in addition to continuing their due diligence investigations of each other, Adobe and Macromedia, along with their respective legal advisors, negotiated the terms of the merger agreement and discussed potential management employment agreements and other employee matters.

On April 16, 2005, the Adobe board of directors held a meeting at which Adobe senior management made presentations to the board regarding the proposed business combination with Macromedia, including the due diligence investigation regarding Macromedia by Adobe and its advisors, the proposed post-merger stock repurchase program of up to $1 billion and organizational and integration matters. Representatives of Goldman Sachs presented its financial analysis regarding the potential business combination. Representatives of Cooley Godward reviewed with the board the proposed terms of the merger agreement, the voting agreements to be entered into by Adobe with directors and executive officers of Macromedia, the irrevocable proxies to be granted to Adobe by such directors and executive officers and related matters. The Adobe board continued its discussion of the potential business combination, including the strategic rationale for such a business combination, as well as the relative potential benefits and risks of combining with Macromedia. Based on the financial analysis and the due diligence presentations, and after extensive board discussion, the Adobe board determined to propose an exchange ratio of 0.69 shares of Adobe common stock for each share of Macromedia common stock (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005).

Reasons for the Merger

The following discussion of the parties' reasons for the merger contains a number of forward-looking statements that reflect the current views of Adobe and/or Macromedia with respect to future events that may have an effect on their future financial performance. Forward-looking statements are subject to risks and uncertainties. Actual results and outcomes may differ materially from the results and outcomes discussed in the forward-looking statements. Cautionary statements that identify important factors that could cause or contribute to differences in results and outcomes include those discussed in "Summary—Forward-Looking Information" and "Risk Factors."

Mutual Reasons for the Merger

Integration of Products and Technologies. We believe that Adobe and Macromedia together can meet more of our customers' needs by integrating our products and technologies to help them communicate better. Many of our customer segments are complementary and in many cases customers in those segments are using products from both companies. The combination of leading development, authoring and collaboration tools, and the complementary functionality of Macromedia Flash and Adobe PDF, are expected to create significant product synergies for our customers. We expect that the combined company will be able to offer increased productivity through streamlined workflow and tighter integration. We believe that, together, Adobe and Macromedia will offer a broad set of products and benefits for customers, including the following:

•: for creative professionals, a more robust authoring and development environment to create, manage and deliver information;
•: for web developers, a better workflow with tighter integration and easier repurposing of content;
•: for digital video professionals, a broader solution that extends to delivery of rich video over the Internet;
•: for mobile consumers, developers, content providers and operators, a broader set of offerings for delivering rich mobile content;
•: for business users, a richer environment for collaboration that enables both on-line and off-line collaboration;
•: for enterprises and enterprise developers, a more complete set of development tools and solutions that help connect back-end systems to people and processes; and
•: for key verticals such as government and education, more comprehensive solutions tailored to their specific needs.

More effective solutions for customers in turn create opportunities for increased sales of the combined company's products.

Increased Innovation and Development. The combined company has the opportunity to define a robust technology platform that delivers compelling, rich content across a wide range of devices and operating systems. We believe that combining the creativity and operational capacities of two leading software companies will allow Adobe and Macromedia to better serve customers by accelerating innovations that change how people experience and interact with information. We believe that the combined company will have significant opportunity to grow into new markets, particularly around non-PC device and enterprise customers. We believe that these opportunities will allow Adobe and Macromedia to better achieve the following goals:

•: offering customers a broad set of tools, services and solutions for design, digital media, documents, and collaboration;
•: developing new market opportunities around non-PC device and enterprise solutions that build upon the combined company's platforms; and
•: enabling the deployment of an industry-defining, cross-media, rich-client technology platform across multiple operating systems and devices, through the complementary functionality of Macromedia Flash and Adobe PDF.

Scale to Better Compete. We believe that the software industry is in a period of consolidation and that there is a developing trend for customers to source a larger portion of their software needs from a smaller number of suppliers. We believe that the combined company will have the scale to better compete in this environment.

Experienced Management Team. It is expected that the combined company will be led by a combination of experienced senior management from both Adobe and Macromedia, which will provide management continuity to support the integration of the two companies.

Adobe's Reasons for the Merger

In addition to considering the strategic factors outlined above, the Adobe board of directors considered the following factors in reaching its conclusion to approve the merger and to recommend that the Adobe stockholders approve the issuance of shares of Adobe common stock in the merger, all of which it viewed as generally supporting its decision to approve the business combination with Macromedia:

•

the complementary nature of Adobe's and Macromedia's product lines;

•

the potential opportunity for the two companies to integrate their software solutions to meet a wider set of customer needs and to combine their technological resources to develop new products with increased functionality and bring them to market faster;

•

the board's and management's assessment that the merger and Macromedia's operating strategy are consistent with Adobe's long-term strategic objectives to grow into new markets, particularly the non-PC device and enterprise segments;

•: the risk that regulators would require the satisfaction of certain regulatory conditions that may have the effect of imposing additional costs on Adobe or otherwise substantially reducing the benefits to Adobe if the merger is consummated;
•: the potential loss of one or more large customers or partners of either company as a result of any such customer's or partner's unwillingness to do business with the combined company;

•: various other applicable risks associated with the combined company and the merger, including those described in the section of this joint proxy statement/prospectus entitled "Risk Factors."

The foregoing information and factors considered by Adobe's board of directors are not intended to be exhaustive but are believed to include all of the material factors considered by Adobe's board of directors. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Adobe board of directors did not find it useful, and did not attempt, to quantify, rank or otherwise assign relative weights to these factors. In considering the factors described above, individual members of the Adobe board of directors may have given different weight to different factors. The Adobe board of directors conducted an overall analysis of the factors described above, including thorough discussions with, and questioning of, Adobe's management and Adobe's legal and financial advisors, and considered the factors overall to be favorable to, and to support, its determination.

Macromedia's Reasons for the Merger

In addition to considering the strategic factors outlined above, the Macromedia board of directors considered the following factors in reaching its conclusion to approve the merger and to recommend that the Macromedia stockholders adopt the merger agreement, all of which it viewed as generally supporting its decision to approve the business combination with Adobe:

•: the complementary nature of Adobe's and Macromedia's product lines;
•: the potential opportunity for the two companies to combine their technological resources to develop new products with increased functionality and bring them to market faster;
•: the potential availability of greater resources for product marketing and distribution;
•: the board's and management's assessment that the merger and Adobe's operating strategy are consistent with Macromedia's long-term operating strategy to grow its business by expanding the scope, platform coverage and depth and breadth of product offerings;
•: the importance of scale in the increasingly competitive market environments in which Macromedia and Adobe operate, and the potential for the merger to enhance Macromedia's ability to compete effectively in those environments;
•: historical and current information concerning Macromedia's and Adobe's respective businesses, financial performance and condition, operations, management, competitive positions and prospects, before and after giving effect to the merger and the merger's potential effect on stockholder value;
•: providing Macromedia stockholders with shares of Adobe common stock in a tax-free exchange at a premium over the market price for Macromedia common stock prior to the announcement of the merger; and
•: the opinion of Macromedia's financial advisor that, as of April 17, 2005 and based on and subject to the assumptions, qualifications and limitations set forth in the opinion, the exchange ratio of 0.69 of a share of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement was fair, from a financial point of view, to holders of Macromedia common stock, and the related financial analyses (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005);
•: the results of the due diligence review of Adobe's businesses and operations;

•

the terms and conditions of the merger agreement, including the following related factors:

•: the expectation that the merger will be treated as a tax-free reorganization for U.S. federal income tax purposes, with the result that the Macromedia stockholders will generally not recognize taxable gain or loss for U.S. federal income tax purposes;
•: the determination that an exchange ratio that is fixed and not subject to adjustment is appropriate to reflect the strategic purpose of the merger and consistent with market practice for a merger of this type and that a fixed exchange ratio fairly captures the respective ownership interests of the Macromedia and Adobe stockholders in the combined company based on valuations of Macromedia and Adobe at the time of the board's approval of the merger agreement and avoids fluctuations caused by near-term market volatility;
•: the fact that shares of Adobe common stock issued to Macromedia stockholders will be registered on Form S-4 and will be freely tradable for Macromedia stockholders who are not affiliates of Macromedia;
•: the reciprocal requirement that the merger agreement be submitted to a vote of the stockholders of Macromedia and that the issuance of shares of Adobe common stock in the merger be submitted to a vote of the stockholders of Adobe;
•: the fact that the merger agreement is not subject to termination solely as a result of any change in the trading price of either Macromedia's or Adobe's stock between signing of the merger agreement and consummation of the merger;
•: the limited number and nature of the conditions to Adobe's obligation to consummate the merger and the limited risk of non-satisfaction of such conditions;
•: Macromedia's rights under the merger agreement to consider certain unsolicited acquisition proposals and to change its recommendation to Macromedia stockholders to adopt the merger agreement under certain circumstances should Macromedia receive a superior proposal, and the limited number of Macromedia shares that would be covered by voting agreements and irrevocable proxies;
•: the conclusion of Macromedia's board of directors that the $103.2 million termination fee, and the circumstances when such fee may be payable, were reasonable in light of the benefits of the merger and commercial practice; and
•: the likelihood that the merger will be consummated on a timely basis, including the likelihood that the merger will receive all necessary regulatory antitrust approvals.

Macromedia's board of directors also considered the potential risks of the merger, including the following:

•: the challenges and costs of combining the operations of two major software companies and the substantial expenses to be incurred in connection with the merger, including the risks that delays or difficulties in completing the integration could adversely affect the combined company's operating results and preclude the achievement of some benefits anticipated from the merger;
•: the price volatility of Adobe's common stock, which may reduce the value of the Adobe common stock that Macromedia stockholders will receive upon the consummation of the merger;
•: the inability of Macromedia's stockholders to realize the long-term value of the successful execution of Macromedia's current strategy as an independent company;
•: the possible loss of key management, technical or other personnel of either of the combining companies as a result of the management and other changes that will be implemented in integrating the businesses;

•: the $103.2 million termination fee payable to Adobe upon the occurrence of certain events, and the potential effect of such termination fee in deterring other potential acquirors from proposing an alternative transaction that may be more advantageous to Macromedia stockholders;
•: the risk of diverting management's attention from other strategic priorities to implement merger integration efforts;
•: the negative impact of any customer confusion or delay in purchase commitments after the announcement of the merger;
•: the risk that the merger might not be consummated in a timely manner or at all;
•: the risk to Macromedia's business, sales, operations and financial results in the event that the merger is not consummated;
•: the risk that the anticipated benefits of product integration and interoperability and cost savings will not be realized; and
•: various other applicable risks associated with the combined company and the merger, including those described in the section of this joint proxy statement/prospectus entitled "Risk Factors."

The foregoing information and factors considered by Macromedia's board of directors are not intended to be exhaustive but are believed to include all of the material factors considered by Macromedia's board of directors. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Macromedia board of directors did not find it useful, and did not attempt, to quantify, rank or otherwise assign relative weights to these factors. In considering the factors described above, individual members of the Macromedia board of directors may have given different weight to different factors. The Macromedia board of directors conducted an overall analysis of the factors described above, including thorough discussions with, and questioning of, Macromedia's management and Macromedia's legal and financial advisors, and considered the factors overall to be favorable to, and to support, its determination.

Opinion of Adobe's Financial Advisor

Goldman, Sachs & Co. delivered its opinion to Adobe's board of directors that, as of April 17, 2005 and based on and subject to the factors and assumptions set forth in the opinion, the exchange ratio of 0.69 shares of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement was fair to Adobe from a financial point of view. The exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

The full text of the written opinion of Goldman Sachs, dated April 17, 2005, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached to this joint proxy statement/prospectus as Annex D. Goldman Sachs provided its opinion for the information and assistance of Adobe's board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Adobe common stock should vote with respect to the issuance of shares of Adobe common stock in the merger.

Please note that the references to the exchange ratio and the market price of Adobe common stock contained in the written opinion of Goldman Sachs attached to this joint proxy statement/prospectus as Annex D and the following summary of the material financial analyses of Goldman Sachs do not give effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

•: the merger agreement;
•: annual reports to stockholders and Annual Reports on Form 10-K of Adobe and Macromedia for the five fiscal years ended December 3, 2004, in the case of Adobe, and March 31, 2004, in the case of Macromedia;
•: Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and any other reports filed pursuant to the Securities Exchange Act of 1934 by Adobe and Macromedia;
•: other communications from Adobe and Macromedia to their respective stockholders;
•: internal financial analyses and forecasts for Macromedia prepared by its management;
•: internal financial analyses and forecasts for Adobe prepared by its management; and
•: financial analyses and forecasts for Macromedia prepared by the management of Adobe, including cost savings and operating synergies projected by the management of Adobe to result from the merger, which are referred to in this discussion as the Synergies.

Goldman Sachs also held discussions with members of the senior managements of Adobe and Macromedia regarding their assessment of the strategic rationale for, and the potential benefits of, the merger and the past and current business operations, financial condition and future prospects of Adobe and Macromedia. In addition, Goldman Sachs reviewed the reported price and trading activity for the shares of Adobe common stock and the shares of Macromedia common stock, compared financial and stock market information for Adobe and Macromedia with similar information for other companies the securities of which are publicly traded, reviewed the financial terms of recent business combinations in the software industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as it considered appropriate.

Goldman Sachs relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with, or reviewed by, it and assumed the accuracy and completeness of this information for purposes of rendering the opinion described above. In that regard, Goldman Sachs assumed, with the consent of Adobe's board of directors, that the forecasts reviewed by Goldman Sachs were reasonably prepared on a basis reflecting the best currently available estimates and judgments of Adobe. Goldman Sachs also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger would be obtained without any adverse effect on Adobe or Macromedia or on the expected benefits of the merger in any way meaningful to its analysis. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of Adobe or Macromedia or any of their respective subsidiaries, nor was any evaluation or appraisal of the assets or liabilities of Adobe or Macromedia or any of their respective subsidiaries furnished to Goldman Sachs. Goldman Sachs' opinion does not address the underlying business decision of Adobe to engage in the merger, nor did Goldman Sachs express any opinion as to the prices at which shares of Adobe common stock will trade at any time.

The following is a summary of the material financial analyses presented by Goldman Sachs to Adobe's board of directors in connection with rendering the opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs, nor does the order of analyses described represent relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs' financial analyses. Except as otherwise noted, the following opinion is based on financial and other conditions in effect on, and the

estimates and other information made available to Goldman Sachs as of, April 17, 2005 and, to the extent it reflects market data, is based on market data as it existed on or before April 15, 2005. Events occurring after such date may affect this opinion and the assumptions used in preparing it, and in particular market data is not necessarily indicative of current market conditions.

Historical Stock Price Analysis. Goldman Sachs reviewed the historical high, median and low closing prices of Adobe common stock and Macromedia common stock for the six-month, one-year, two-year and three-year periods ended April 15, 2005. The following table presents the results of this review:

Historical Price to Earnings Ratio Analysis. Goldman Sachs reviewed the historical price to earnings ratios for Adobe and Macromedia for calendar years 1999, 2000, 2001, 2002, 2003, 2004, 2005 (through April 15, 2005) and as of April 15, 2005. The historical price to earnings ratios were determined by dividing the closing price per share of Adobe common stock and Macromedia common stock, respectively, by the daily median next-twelve-month rolling earnings per share projections for Adobe and Macromedia, respectively, provided by Institutional Brokers Estimate System, which is referred to in this discussion as IBES, which is a data service that compiles estimates issued by securities research analysts. Goldman Sachs also calculated the Macromedia median price to earnings ratio as a percentage of the Adobe median price to earnings ratio for each of these respective periods. The following table presents the results of these calculations:

	1999		2000		2001		2002		2003		2004		2005 Year to Date		As of April 15, 2005
Adobe Median Price to Earnings Ratio	27.1	x	54.3	x	30.6	x	29.0	x	31.6	x	29.9	x	31.1	x	28.2	x
Macromedia Median Price to Earnings Ratio	58.5	x	77.9	x	21.3	x	43.8	x	33.7	x	30.2	x	36.0	x	33.3	x
Macromedia Median Price to Earnings Ratio as a Percentage of Adobe Median Price to Earnings Ratio	216	%	143	%	70	%	151	%	107	%	101	%	116	%	118	%

Historical Exchange Ratio Analysis. Goldman Sachs reviewed the implied historical exchange ratios determined by dividing the closing price per share of Macromedia common stock by the closing price per share of Adobe common stock over the five-day, 10-day, 20-day, 30-day, 60-day, 90-day, 180-day and 360-day trading periods ended April 15, 2005, as well as the implied premium of the exchange ratio of 0.69 shares of Adobe common stock to be issued in exchange for each share of Macromedia

common stock pursuant to the merger agreement (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005) to the implied historical exchange ratios and the closing price per share of Macromedia common stock over each of the respective trading periods. The following table presents the results of these calculations:

Historical Period	Implied Historical Exchange Ratio(1)	Implied Premium of Actual Exchange Ratio to Implied Historical Exchange Ratio(1)		Implied Premium of Actual Exchange Ratio to Historical Macromedia Share Price(1)
April 15, 2005	0.5514	25.1	%	25.1	%

Selected Companies Analysis. Goldman Sachs reviewed and compared certain financial information for Adobe and Macromedia to corresponding financial information, ratios and public market multiples for the following publicly traded corporations in the digital media and content management sectors of the software industry:

Digital Media

•: Autodesk, Inc.
•: Avid Technology, Inc.
•: Getty Images, Inc.
•: Openwave Systems Inc.
•: RealNetworks, Inc.
•: WebEx Communications, Inc.

Content Management

•: Actuate Corporation
•: FileNet Corporation
•: Interwoven, Inc.
•: Open Text Corporation
•: Stellent, Inc.
•: Vignette Corporation

Although none of the selected companies is directly comparable to Adobe or Macromedia, the companies included were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to certain operations of Adobe and Macromedia.

Goldman Sachs also calculated and compared various financial multiples and ratios based on historical financial data as of April 15, 2005, information obtained from SEC filings and estimates provided by IBES. The multiples and ratios of Adobe, Macromedia and each of the selected companies were based on estimates provided by IBES and the most recent publicly available information and were calculated using closing stock prices on April 15, 2005. With respect to Adobe, Macromedia and the selected companies, Goldman Sachs calculated the multiple of price to calendar year 2005 and 2006 IBES estimated earnings. For purposes of these calculations, Goldman Sachs adjusted each (a) Adobe November 30 fiscal year end to a December 31 calendar year end and (b) Macromedia March 31 fiscal year end to a December 31 calendar year end. The following table presents the results of this analysis:

	Selected Companies
	Range	Mean	Median	Adobe	Macromedia
Price/2005 CYE Earnings	14.2x - 56.0x	27.5x	27.1x	28.5x	33.3x
Price/2006 CYE Earnings	12.6x - 56.0x	23.6x	22.7x	26.0x	27.0x

Goldman Sachs also calculated the ratio of price to calendar year 2006 IBES estimated earnings as a multiple of IBES median five-year earnings per share compound annual growth rate. The following table presents the results of this analysis:

	Selected Companies
	Range	Adobe		Macromedia
Price/2006 CYE Earnings	12.6x - 56.0x	26.0	x	27.0	x
Estimated 5-Year Earnings Per Share Compound Annual Growth Rate	12.0% - 30.0%	15.0	%	20.0	%
Ratio of Calendar 2006 Price to Earnings Ratio to 5-Year EPS Compound Annual Growth Rate	0.7x - 2.0x	1.7	x	1.3	x

Pro Forma Merger Analysis. Goldman Sachs analyzed the potential pro forma impact of the merger on cash earnings per share, which is defined as GAAP earnings per share adjusted for purchase accounting adjustments, including deferred revenue write-down and amortization of intangibles and other one-time costs, and earnings per share including deferred revenue adjustment and amortization of intangibles from the point of view of the holders of Adobe common stock prior to the merger based upon (a) earnings estimates provided by Fulcrum Global Partners LLC, in the case of Adobe, and RBC Capital Markets, in the case of Macromedia, which are collectively referred to in this discussion as the Street Case, and (b) earnings estimates for Adobe and Macromedia based on estimates for Adobe and Macromedia arising from projections prepared by Adobe's management, which is referred to in this discussion as the Adobe Management Case. For purposes of these calculations, Goldman Sachs (a) assumed each Adobe November 30 fiscal year end to be a December 31 calendar year end and (b) adjusted each Macromedia March 31 fiscal year end to a December 31 calendar year end.

Based on the closing price per share of Adobe common stock as of April 15, 2005, the exchange ratio of 0.69 shares of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005), the number of shares and options to purchase shares of Adobe common stock outstanding as of April 7, 2005 and the number of shares and options to purchase shares of Macromedia common stock outstanding as of April 8, 2005, this analysis indicated that under both the Street Case and the Adobe Management Case, the merger would be dilutive before Synergies to Adobe's cash earnings per share and earnings per share including deferred revenue

adjustment and amortization of intangibles. This analysis also indicated that under both the Street Case and the Adobe Management Case, the transaction would be slightly accretive to Adobe's cash earnings per share if the Synergies were included.

Goldman Sachs also analyzed the potential pro forma impact of the merger on cash earnings per share based on a range of estimated revenues, some of the values of which were lower than the estimates contained in the Street Case and the Adobe Management Case, and a range of estimated Synergies. This analysis indicated that the merger would be break-even to slightly accretive to Adobe's cash earnings per share.

Contribution Analysis. Goldman Sachs performed a contribution analysis in which it analyzed and compared the relative implied contributions of Adobe and Macromedia on a percentage basis based on actual calendar year 2004 revenue and estimated calendar year 2005 and 2006 revenue, actual calendar year 2004 operating income and estimated calendar year 2005 and 2006 operating income and actual calendar year 2004 cash net income, which is defined as GAAP net income adjusted for purchase accounting adjustments, including deferred revenue write-down and amortization of intangibles and other one-time costs, and estimated calendar year 2005 and 2006 cash net income of the combined company as adjusted for the net debt positions of Adobe and Macromedia. For purposes of these calculations, net debt was defined as total indebtedness less cash, cash equivalents and short-term investments. Adobe's and Macromedia's relative implied contributions to the combined company, as adjusted for net debt, are referred to in this discussion as implied equity contributions. The contribution analysis that Goldman Sachs performed, however, did not reflect any Synergies, purchase accounting adjustments or merger-related costs resulting from the consummation of the merger.

Goldman Sachs performed this contribution analysis employing both the Street Case and the Adobe Management Case. For purposes of these calculations, Goldman Sachs (a) assumed each Adobe November 30 fiscal year end to be a December 31 calendar year end and (b) adjusted each Macromedia March 31 fiscal year end to a December 31 calendar year end. For purposes of these calculations, Goldman Sachs also reviewed the fully diluted equity market capitalization of Adobe and Macromedia, respectively, on April 15, 2005 and used net debt information for Adobe and Macromedia based on their latest publicly available filings as of April 15, 2005. The results of Goldman Sachs' calculations are as follows:

Street Case

	Adobe Implied Equity Contribution to Combined Company		Macromedia Implied Equity Contribution to Combined Company
2004A Revenue	79.9	%	20.1	%
2005E Revenue	80.5	%	19.5	%
2006E Revenue	80.4	%	19.6	%
2004A Operating Income	88.0	%	12.0	%
2005E Operating Income	87.8	%	12.2	%
2006E Operating Income	85.5	%	14.5	%
2004A Cash Net Income	87.7	%	12.3	%
2005E Cash Net Income	87.8	%	12.2	%
2006E Cash Net Income	85.1	%	14.9	%

Adobe Management Case

	Adobe Implied Equity Contribution to Combined Company		Macromedia Implied Equity Contribution to Combined Company
2004A Revenue	79.9	%	20.1	%
2005E Revenue	80.2	%	19.8	%
2006E Revenue	79.7	%	20.3	%
2004A Operating Income	88.0	%	12.0	%
2005E Operating Income	88.2	%	11.8	%
2006E Operating Income	86.4	%	13.6	%
2004A Cash Net Income	87.7	%	12.3	%
2005E Cash Net Income	88.4	%	11.6	%
2006E Cash Net Income	86.5	%	13.5	%

Based upon the exchange ratio of 0.69 shares of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005), Goldman Sachs calculated that holders of Adobe common stock and holders of Macromedia common stock would hold 82.1% and 17.9%, respectively, of the combined company on a treasury method basis.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs' analyses and opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Adobe, Macromedia or the contemplated transaction.

Goldman Sachs prepared these analyses for purposes of Goldman Sachs' providing its opinion to Adobe's board of directors as to the fairness from a financial point of view to Adobe of the exchange ratio of 0.69 shares of Adobe common stock to be issued in exchange for each share of Macromedia common stock pursuant to the merger agreement (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005). These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Adobe, Macromedia, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

The merger consideration was determined by Adobe and Macromedia through arm's length negotiations between Adobe and Macromedia and was approved by Adobe's board of directors.

As described above, Goldman Sachs' opinion to Adobe's board of directors was one of many factors taken into consideration by Adobe's board of directors in making its determination to approve the merger agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with its fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex D.

estate, corporate and other purposes. Goldman Sachs has acted as financial advisor to Adobe in connection with, and has participated in certain of the negotiations leading to, the merger. In addition, Goldman Sachs and its affiliates have provided certain investment banking services to Adobe and Macromedia from time to time. Goldman Sachs and its affiliates also may provide investment banking services to Adobe and Macromedia in the future. In connection with the above-described investment banking services Goldman Sachs and its affiliates have received, and may receive, compensation.

Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to Adobe, Macromedia and their affiliates, may actively trade the debt and equity securities (or related derivative securities) of Adobe and Macromedia for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

Adobe's board of directors selected Goldman Sachs as its financial advisor because Goldman Sachs is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement, Adobe engaged Goldman Sachs to act as its financial advisor in connection with a potential transaction with Macromedia. Pursuant to the terms of this engagement letter, Adobe has agreed to pay Goldman Sachs a fee of $15 million. Of this amount, a fee of $1.25 million was payable upon execution of the merger agreement and the remainder is payable upon the consummation of the merger. In the event that the merger agreement is terminated or the merger is otherwise not consummated, Adobe has also agreed to pay Goldman Sachs a portion of any "break-up" or similar fee paid to Adobe or its affiliates as a result of such termination or failure to consummate the merger equal to 15% of the amount by which such fee exceeds Adobe's expenses related to the potential transaction with Macromedia, but in no event will the total fees payable to Goldman Sachs exceed $15 million. In addition, Adobe has agreed to reimburse Goldman Sachs for its expenses, including attorneys' fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

Opinion of Macromedia's Financial Advisor

Macromedia retained Morgan Stanley & Co. Incorporated to provide it with financial advisory services and a fairness opinion in connection with a possible merger, sale or other business combination. Macromedia's board of directors selected Morgan Stanley to act as its financial advisor based on Morgan Stanley's qualifications, expertise and reputation and its knowledge of the business and affairs of Macromedia. At the meeting of the Macromedia board of directors on April 17, 2005, Morgan Stanley rendered its oral opinion, subsequently confirmed in writing, that as of April 17, 2005, and based upon and subject to the assumptions, qualifications and limitations set forth in the opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to holders of shares of Macromedia common stock.

The full text of the written opinion of Morgan Stanley, dated as of April 17, 2005, is attached to this joint proxy statement/prospectus as Annex E. The opinion sets forth, among other things, the assumptions made, procedures followed and matters considered in and limitations on the scope of the review undertaken by Morgan Stanley in rendering its opinion. We encourage you to read the entire opinion carefully. Morgan Stanley's opinion is directed to Macromedia's board of directors and addresses only the fairness from a financial point of view of the exchange ratio pursuant to the merger agreement to holders of shares of Macromedia common stock as of the date of the opinion. It does not address any other aspects of the merger and does not constitute a recommendation to any holder of Macromedia common stock as to how to vote at the Macromedia special meeting. The summary of the opinion of Morgan Stanley set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of the opinion.

Please note that the references to the exchange ratio and the market price of Adobe common stock contained in the written opinion of Morgan Stanley attached to this joint proxy statement/prospectus as Annex E and the following summary of the material analyses of Morgan Stanley do not give effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

In connection with rendering its opinion, Morgan Stanley, among other things:

•: reviewed certain publicly available financial statements and other business and financial information of Adobe and Macromedia;
•: reviewed certain internal financial statements and projections and operating data concerning Adobe and Macromedia, prepared by the managements of Adobe and Macromedia, respectively;

•: reviewed the reported prices and trading activity for the Adobe common stock and the Macromedia common stock;

In arriving at its opinion, Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information reviewed by Morgan Stanley for the purposes of its opinion. With respect to the internal financial statements, including information relating to the strategic, financial and operational benefits anticipated from the merger and assessments regarding the prospects of Adobe and Macromedia, Morgan Stanley assumed that they were reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of Adobe and Macromedia, respectively. In addition, Morgan Stanley assumed that the merger would be consummated in accordance with the terms set forth in the merger agreement without material modification, waiver or delay, including, among other things, that the merger would be treated as a tax-free reorganization pursuant to the Internal Revenue Code of 1986, as amended. Morgan Stanley also assumed that in connection with the receipt of all the necessary regulatory approvals for the proposed merger, no restrictions would be imposed or delays will result that would have a material

adverse affect on the contemplated benefits expected to be derived in the proposed merger. Morgan Stanley is not a legal or regulatory advisor and has relied upon, without independent verification, the assessment by Macromedia and its legal and regulatory advisors with respect to such matters.

Morgan Stanley relied upon, without independent verification, the assessment by the managements of Adobe and Macromedia of: (i) the strategic, financial and other benefits expected to result from the merger; (ii) the timing and risks associated with the integration of Adobe and Macromedia; (iii) their ability to retain key employees of Adobe and Macromedia, respectively; and (iv) the validity of, and risks associated with, Adobe's and Macromedia's existing and future intellectual property, products, services and business models. Morgan Stanley did not make any independent valuation or appraisal of the assets or liabilities of Adobe and Macromedia, nor was Morgan Stanley furnished with any such appraisals. Morgan Stanley's opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Morgan Stanley as of, April 17, 2005. Events occurring after such date may affect its opinion and the assumptions used in preparing it, and Morgan Stanley does not assume any obligation to update, revise or reaffirm its opinion. In arriving at its opinion, Morgan Stanley was not authorized to solicit, and did not solicit, interest from any party with respect to an acquisition, business combination or other extraordinary transaction involving Macromedia.

The following is a brief summary of the material analyses performed by Morgan Stanley in connection with its oral opinion and the preparation of its written opinion letter dated April 17, 2005. The various analyses summarized below were based on closing prices for the common stock of Adobe and Macromedia as of April 15, 2005, the last full trading day preceding the day of the meeting of Macromedia's board of directors to consider and approve the merger with Adobe. Although each analysis was provided to the Macromedia board of directors, in connection with arriving at its opinion, Morgan Stanley considered all of its analyses as a whole and did not attribute any particular weight to any analysis described below. Some of these summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

On April 17, 2005, Adobe and Macromedia entered into a merger agreement whereby each holder of Macromedia common stock would be entitled to receive 0.69 of a share of Adobe common stock for each share of Macromedia common stock. The exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005. Morgan Stanley calculated that as a result of the merger, Macromedia's stockholders would own approximately 18.1% of the combined company on a fully diluted basis using the treasury stock method.

Macromedia, Inc.

Trading Range Analysis. Morgan Stanley performed a trading range analysis to provide background and perspective with respect to the historical share prices of Macromedia common stock. Morgan Stanley reviewed the range of closing prices of Macromedia common stock for various periods ended on April 15, 2005. Morgan Stanley observed the following:

Period Ended April 15, 2005		Range of Closing Prices
Last 30 Trading Days		$32.40 - $36.31
Last 60 Trading Days		$29.99 - $36.89
Last 90 Trading Days		$25.99 - $36.89
Last 12 Months		$18.21 - $36.89
Last 3 Years		$5.99 - $36.89

Based on Adobe's common stock price per share of $60.66 as of April 15, 2005 and the exchange ratio of 0.69 pursuant to the merger agreement (Adobe's common stock price per share as of April 15, 2005 was $30.33 and the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005), Morgan Stanley noted that the implied value per share of Macromedia common stock was $41.86.

Indexed Price Performance. Morgan Stanley reviewed the share price performance of Macromedia, Adobe and indices composed of average stock prices of infrastructure software category leaders and infrastructure software tools companies for the six month and twelve month periods ending April 15, 2005, and compared the performance of Macromedia, Adobe and these indices to the performance of the NASDAQ National Market during the same period. The infrastructure software category leaders index included the companies listed below, and the infrastructure software tools companies index included the companies listed below.

Morgan Stanley noted the following:

Company/Index	% Price Change Since October 15, 2004		% Price Change Since April 15, 2004
Macromedia	49	%	78	%
Adobe	18	%	47	%
Infrastructure Software Category Leaders Index	(9	)%	(1	)%
Infrastructure Software Tools Companies Index	(2	)%	(25	)%
NASDAQ National Market	0	%	(5	)%

Comparable Company Analysis. Morgan Stanley performed a comparable company analysis, which attempts to provide an implied value of a company by comparing it to similar companies. Morgan Stanley compared certain financial information of Macromedia with publicly available consensus estimates for other companies that shared similar business characteristics of Macromedia. The companies used in this comparison included the following infrastructure software companies:

Infrastructure Software Category Leaders:

•: Adobe Systems Incorporated
•: Autodesk, Inc.
•: Cognos Incorporated
•: Oracle Corporation
•: Mercury Interactive Corporation
•: Microsoft Corporation
•: Tibco Software Inc.

Infrastructure Software Tools Companies:

•: Borland Software Corporation
•: Business Objects S.A.
•: Citrix Systems, Inc.
•: FileNet Corporation

•: Open Text Corporation
•: Openwave Systems Inc.
•: RealNetworks, Inc.
•: Red Hat, Inc.
•: WebEx Communications, Inc.

For purposes of this analysis, Morgan Stanley analyzed the following statistics of each of these companies for comparison purposes:

•: the ratios of aggregate value, defined as market capitalization plus total debt less cash, cash equivalents and short-term investments, to estimated calendar year 2005 and 2006 revenues (in each case, based on publicly available consensus equity research estimates); and
•: the ratios of price to estimated earnings per share for calendar year 2005 and calendar year 2006 (in each case, based on publicly available consensus equity research estimates).

Based on the analysis of the relevant metrics for each of the comparable companies, Morgan Stanley selected representative ranges of financial multiples of the comparable companies and applied this range of multiples to the relevant Macromedia financial statistic. For purposes of estimated calendar year 2005 and 2006 revenues and earnings per share Morgan Stanley utilized publicly available consensus equity research estimates as of April 15, 2005. Based on Macromedia's outstanding shares and options as of April 15, 2005, Morgan Stanley estimated the implied value per Macromedia share as of April 15, 2005 as follows:

Calendar Year Financial Statistic	Comparable Company Multiple Range	Implied Value Per Share of Macromedia
Aggregate Value to Estimated 2005 Revenue	4.0x - 5.5x	$29.44 - $37.92
Aggregate Value to Estimated 2006 Revenue	3.5x - 5.0x	$29.01 - $38.52
Price to Estimated 2005 Earnings Per Share	25.0x - 35.0x	$25.44 - $35.62
Price to Estimated 2006 Earnings Per Share	22.5x - 30.0x	$27.90 - $37.20

Morgan Stanley noted that based on Adobe's common stock price per share of $60.66 as of April 15, 2005 and the exchange ratio of 0.69 pursuant to the merger agreement (Adobe's common stock price per share as of April 15, 2005 was $30.33 and the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005), the implied value per share of Macromedia common stock was $41.86.

No company utilized in the comparable company analysis is identical to Macromedia. In evaluating comparable companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Macromedia, such as the impact of competition on the businesses of Macromedia and the industry generally, industry growth and the absence of any adverse material change in the financial condition and prospects of Macromedia or the industry or in the financial markets in general. Mathematical analysis (such as determining the average or median) is not in itself a meaningful method of using peer group data.

Discounted Equity Value Analysis. Morgan Stanley performed a discounted equity value analysis, which is designed to provide insight into the future value of a company's common equity as a function of the company's future earnings and its current forward price to earnings multiple, and the resulting value is subsequently discounted to arrive at a company's present value for its stock price. In

connection with this analysis, Morgan Stanley calculated a range of present equity values per share for Macromedia on a standalone basis. To calculate the discounted equity value, Morgan Stanley utilized the fiscal year 2007 publicly available consensus equity research earnings estimate as a "Street Case" and the fiscal year 2007 earnings estimate provided by Macromedia's management as a "Macromedia Management Tops Down Case". Morgan Stanley applied a range of price to earnings multiples to these estimates and applied a discount rate of 15% (calculated based on current predicted equity research estimates of Macromedia's cost of equity) to these ranges.

The following table summarized Morgan Stanley's analysis:

Financial Statistic		Forward Price to Earnings Multiple Range		Implied Value Per Share for Macromedia
Street Case		25.0x - 35.0x		$28.26 - $39.57
Macromedia Management Tops Down Case		25.0x - 35.0x		$33.23 - $46.52

Securities Research Analysts' Price Targets. Morgan Stanley reviewed and analyzed future public market trading price targets for Macromedia common stock prepared and published by equity research analysts. These targets reflect each analyst's estimate of the future public market trading price of Macromedia common stock. The range of undiscounted 12-month analyst price targets for Macromedia was $32.00 to $45.00. Based on Adobe's common stock price per share of $60.66 as of April 15, 2005 and the exchange ratio of 0.69 pursuant to the merger agreement (Adobe's common stock price per share as of April 15, 2005 was $30.33 and the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005), Morgan Stanley noted that the implied value per share of Macromedia common stock was $41.86.

The public market trading price targets published by the securities research analysts do not necessarily reflect current market trading prices for Macromedia common stock and these estimates are subject to uncertainties, including the future financial performance of Macromedia and future financial market conditions.

Historical Exchange Ratio Range Analysis. Morgan Stanley reviewed the ratios of the range of closing prices of Macromedia common stock divided by the corresponding closing prices of Adobe common stock over various periods ended on April 15, 2005. For each of the periods reviewed, Morgan Stanley observed the relevant range of low and high exchange ratios. Based on the closing price per share of $60.66 of Adobe common stock as of April 15, 2005 (the closing price per share of Adobe common stock as of April 15, 2005 was $30.33 after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of

record as of May 2, 2005), Morgan Stanley calculated a range of implied values per share of Macromedia. The following table summarized Morgan Stanley's analysis:

Period Ended April 15, 2005	Range of Exchange Ratios(1)	Implied Value Per Share of Macromedia
Last 30 Trading Days	0.489 - 0.555	$29.68 - $33.68
Last 60 Trading Days	0.489 - 0.602	$29.68 - $36.50
Last 90 Trading Days	0.449 - 0.602	$27.24 - $36.50
Last 12 Months	0.385 - 0.602	$23.35 - $36.50
Last 3 Years	0.274 - 0.717	$16.61 - $43.52

(1): Does not give effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

Exchange Ratio Premium Analysis. Morgan Stanley reviewed the ratios of the closing prices of Macromedia common stock divided by the corresponding closing prices of Adobe common stock over various periods ended April 15, 2005 to provide background information and perspective on the average exchange ratio and its premium or discount to the exchange ratio set forth in the merger agreement during certain periods. The ratios are referred to as average exchange ratios. Morgan Stanley examined the premiums represented by the exchange ratio of 0.69 pursuant to the merger agreement (the exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005) over these period average exchange ratios, and found them to be as follows:

Period Ended April 15, 2005	Average Exchange Ratio(1)	Transaction Exchange Ratio (0.69) Premium To Average Exchange Ratio(1)
April 15, 2005	0.551	25	%
Last 5 Trading Days	0.548	26	%
Last 10 Trading Days	0.530	30	%
Last 20 Trading Days	0.517	33	%
Last 30 Trading Days	0.524	32	%
Last 60 Trading Days	0.543	27	%
Last 90 Trading Days	0.521	32	%

(1): Does not give effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

Morgan Stanley noted that the exchange ratio pursuant to the merger agreement was 0.69. The exchange ratio is now 1.38 shares of Adobe common stock for each share of Macromedia common stock after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005.

Analysis of Precedent Transactions. Morgan Stanley also performed a precedent transaction analysis, which is designed to imply a value of a company based on publicly available financial terms and premiums of selected transactions that share some characteristics with the merger. In connection with its analysis, Morgan Stanley compared publicly available statistics for twelve selected software sector transactions between January 1, 2002 and April 15, 2005 in which the target company was

publicly traded and transaction values were greater than $1.0 billion. The following is a list of these transactions:

Selected Precedent Transactions (Target/Acquiror)

•: Ascential Software Corporation/International Business Machines Corporation
•: Documentum, Inc./EMC Corporation
•: Illuminet Holdings, Inc./VeriSign, Inc.
•: J.D. Edwards & Company/PeopleSoft, Inc.
•: LEGATO Systems, Inc./EMC Corporation
•: Navision A.S./Microsoft Corporation
•: NetScreen Technologies, Inc./Juniper Networks, Inc.
•: Overture Services, Inc./Yahoo! Inc.
•: PayPal, Inc./eBay Inc.
•: Rational Software Corporation/International Business Machines Corporation
•: VERITAS Software Corporation/Symantec Corporation
•: Visio Corporation/Microsoft Corporation

For each transaction noted above Morgan Stanley noted the following financial statistics where available: (1) aggregate value to next twelve months estimated revenues; (2) price to next twelve months estimated earnings per share; (3) implied premium to price one trading day prior to announcement; (4) implied exchange ratio premium to 30 trading day average exchange ratio; (5) implied exchange ratio premium to 60 trading day average exchange ratio; and (6) implied exchange ratio premium to 90 trading day average exchange ratio. The following table summarized Morgan Stanley's analysis:

Precedent Transaction Financial Statistic	Reference Range	Implied Value Per Share	Macromedia/Adobe Financial Statistic
Aggregate Value to Next Twelve Months Revenues	2.5x - 7.0x	$21.20 - $47.13	6.1x
Price to Next Twelve Months Earnings Per Share	30.0x - 50.0x	$31.80 - $53.00	39.5x
Premium to 1-day prior price	15% - 40%	$38.47 - $46.83	25%
Premium to 30-day average price	15% - 35%	$36.52 - $42.87	32%
Premium to 60-day average exchange ratio	15% - 45%	$37.90 - $47.79	27%
Premium to 90-day average exchange ratio	10% - 50%	$34.79 - $47.44	32%

No company or transaction utilized in the precedent transaction analysis of stock price premiums paid is identical to Macromedia or Adobe or the merger. In evaluating the precedent transactions, Morgan Stanley made judgments and assumptions with regard to general business, market and financial conditions and other matters, which are beyond the control of Adobe and Macromedia, such as the impact of competition on the business of Macromedia, Adobe or the industry generally, industry growth and the absence of any adverse material change in the financial condition of Macromedia, Adobe or the industry or in the financial markets in general, which could affect the public trading value of the companies and the aggregate value of the transactions to which they are being compared.

Relative Contribution Analysis. Morgan Stanley compared Adobe and Macromedia stockholders' respective percentage ownership of the combined company to Macromedia's and Adobe's respective percentage contribution (and the implied ownership based on such contribution) to the combined company using actual calendar year 2004 and estimated calendar year 2005 and 2006 operating income and net income. For purposes of the analysis Morgan Stanley utilized publicly available consensus equity research estimates as a "Street Case" for Macromedia and estimates provided by Macromedia's management as a "Macromedia Management Tops Down Case," and compared these respective metrics to publicly available consensus equity research estimates for Adobe. Based on Macromedia's respective implied ownership and based on the closing price per share of Adobe common stock of $60.66 as of April 15, 2005 (the closing price per share of Adobe common stock as of April 15, 2005 was $30.33 after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005), Morgan Stanley calculated an implied value per share of Macromedia.

Morgan Stanley noted that the price per share of Adobe common stock as of April 15, 2005 was $60.66 (the price per share of Adobe common stock as of April 15, 2005 was $30.33 after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005).

Comparable Company Analysis. Morgan Stanley compared certain financial information of Adobe with publicly available consensus estimates for other companies that shared similar business characteristics of Adobe. The following is a list of those companies:

Infrastructure Software Category Leaders:

•: Autodesk, Inc.
•: Cognos Incorporated
•: Oracle Corporation
•: Macromedia, Inc.
•: Mercury Interactive Corporation
•: Microsoft Corporation
•: Tibco Software Inc.

Infrastructure Software Tools Companies:

•: Borland Software Corporation
•: Business Objects S.A.
•: Citrix Systems, Inc.
•: FileNet Corporation
•: Open Text Corporation
•: Openwave Systems Inc.
•: RealNetworks, Inc.
•: Red Hat, Inc.
•: WebEx Communications, Inc.

For purposes of this analysis, Morgan Stanley analyzed the following statistics of each of these companies for comparison purposes:

•: the ratios of aggregate value, defined as market capitalization plus total debt less cash, cash equivalents and short-term investments, to estimated calendar year 2005 and 2006 revenues (in each case, based on publicly available consensus equity research estimates); and
•: the ratios of price to estimated earnings per share for calendar year 2005 and 2006 (in each case, based on publicly available consensus equity research estimates).

Based on the analysis of the relevant metrics for each of the comparable companies, Morgan Stanley selected the representative ranges of financial multiples of the comparable companies and applied this range of multiples to the relevant Adobe financial statistic. For purposes of estimated calendar year 2005 and 2006 revenues and earnings per share Morgan Stanley utilized publicly available consensus equity research estimates as of April 15, 2005. Based on Adobe's outstanding shares and options as of April 15, 2005, Morgan Stanley estimated the implied value per Adobe share as of April 15, 2005 as follows:

Calendar Year Financial Statistic	Comparable Company Multiple Range	Implied Value Per Share for Adobe(1)
Aggregate Value to Estimated 2005 Revenue	5.0x - 8.0x	$44.38 - $65.70
Aggregate Value to Estimated 2006 Revenue	4.5x - 7.0x	$44.10 - $63.73
Price to Estimated 2005 Earnings Per Share	25.0x - 35.0x	$53.25 - $74.55
Price to Estimated 2006 Earnings Per Share	22.5x - 30.0x	$52.31 - $69.75

No company utilized in the comparable company analysis is identical to Adobe. In evaluating the comparable companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Adobe, such as the impact of competition on the businesses of Adobe and the industry generally, industry growth and the absence of any adverse material change in the financial condition and prospects of Adobe or the industry or in the financial markets in general. Mathematical analysis (such as determining the average or median) is not in itself a meaningful method of using peer group data.

Discounted Equity Value Analysis. Morgan Stanley calculated a range of present equity values per share for Adobe on a standalone basis. To calculate the discounted equity value, Morgan Stanley utilized the calendar year 2006 publicly available consensus equity research revenue estimate, and applied projected annual growth rates of 10% to 15%, projected operating margins of 35% to 37%, and a tax rate of 25% to derive a range of calendar year 2007 earnings estimates. Morgan Stanley applied a range of price to earnings multiples to these estimates and applied a discount rate of 12% (calculated based on current predicted equity research estimates of Adobe's cost of equity) to these ranges.

The following table summarizes Morgan Stanley's analysis:

Financial Statistic	Adobe Financial Statistic (Calendar Year 2007 Earnings Estimates)(1)		Calendar Year 2006 Price to Earnings Multiple Range	Implied Value Per Share of Adobe(1)
2007 estimated calendar year earnings per share (10% growth; 35% operating margin)	$	2.42	25.0x - 35.0x	$48.32 - $67.65
2007 estimated calendar year earnings per share (12.5% growth; 36% operating margin)	$	2.55	25.0x - 35.0x	$50.74 - $71.04
2007 estimated calendar year earnings per share (15% growth; 37% operating margin)	$	2.67	25.0x - 35.0x	$53.23 - $74.52

Securities Research Analysts' Price Targets. Morgan Stanley reviewed and analyzed future public market trading price targets for Adobe common stock prepared and published by equity research analysts. These targets reflect each analyst's estimate of the future public market trading price of Adobe common stock. The range of undiscounted 12-month analyst price targets for Adobe was $55.00 to $80.00 (the range of undiscounted 12-month analyst price targets for Adobe was $27.50 to $40.00 after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005). Morgan Stanley noted that the price per share of Adobe common stock as of April 15, 2005 was $60.66 (the price per share of Adobe common stock as of April 15, 2005 was $30.33 after giving effect to the two-for-one stock split in the form of a stock dividend of Adobe common stock paid on May 23, 2005 to Adobe stockholders of record as of May 2, 2005).

Morgan Stanley noted that the public market trading price targets published by the securities research analysts do not necessarily reflect current market trading prices for Adobe common stock and these estimates are subject to uncertainties, including the future financial performance of Adobe and future financial market conditions.

In connection with the review of the merger by Macromedia's board of directors, Morgan Stanley performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley's view of the actual value of Macromedia or Adobe. In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters. Many of these assumptions

are beyond the control of Macromedia or Adobe. Any estimates contained in Morgan Stanley's analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness of the exchange ratio pursuant to the merger agreement from a financial point of view to holders of shares of Macromedia common stock and in connection with the delivery of its opinion dated April 17, 2005 to Macromedia's board of directors. These analyses do not purport to be appraisals or to reflect the prices at which shares of common stock of Macromedia or Adobe might actually trade.

The merger consideration was determined by Adobe and Macromedia through arm's length negotiations between Adobe and Macromedia and was approved by Macromedia's board of directors.

In addition, Morgan Stanley's opinion and its presentation to Macromedia's board of directors was one of many factors taken into consideration by Macromedia's board of directors in deciding to approve the merger. Consequently, the analyses as described above should not be viewed as determinative of the opinion of Macromedia's board of directors with respect to the exchange ratio or of whether Macromedia's board of directors would have been willing to agree to a different exchange ratio.

Macromedia's board of directors retained Morgan Stanley based upon Morgan Stanley's qualifications, experience and expertise. Morgan Stanley is an internationally recognized investment banking and advisory firm. Morgan Stanley, as part of its investment banking and financial advisory business, is continuously engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate, estate and other purposes. In the past, Morgan Stanley and its affiliates have provided financial advisory and financing services for Adobe and Macromedia and received fees for such services. In the ordinary course of Morgan Stanley's trading and brokerage activities, Morgan Stanley or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for its own account or for the account of customers in the equity and other securities of Macromedia, Adobe or any other parties involved in the merger. In addition, from time to time Morgan Stanley has entered into and may enter into agreements to purchase software and services from Adobe and Macromedia in connection with Morgan Stanley business.

Under the terms of its engagement letter, Morgan Stanley provided Macromedia financial advisory services and a financial opinion in connection with the merger. Pursuant to the terms of this engagement letter, Macromedia has agreed to pay Morgan Stanley a fee of 0.4% of Macromedia's fully diluted market value upon the consummation of the merger (based upon a five-trading day average of the market price of Adobe's common stock). Of this amount, a fee of $1.5 million was payable upon delivery of Morgan Stanley's written fairness opinion and the remainder is payable upon the consummation of the merger. Macromedia has also agreed to reimburse Morgan Stanley for other expenses, including attorneys' fees, incurred in connection with its engagement. In addition, Macromedia has agreed to indemnify Morgan Stanley and any of its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including any liabilities under the federal securities laws relating to or arising out of its engagement and any related transactions.

Interests of Macromedia's Executive Officers and Directors in the Merger

In considering the recommendation of the Macromedia board of directors with respect to adopting the merger agreement, Macromedia stockholders should be aware that certain members of the board of directors and executive officers of Macromedia have interests in the merger that are different from, or in addition to, their interests as Macromedia stockholders. These interests may create an appearance of

a conflict of interest. The Macromedia board of directors was aware of these potential conflicts of interest during its deliberations on the merits of the merger and in making its decision in approving the merger, the merger agreement and the related transactions.

Combined Company Board of Directors. The merger agreement provides that Adobe will cause Robert K. Burgess to be elected or appointed to the board of directors of Adobe as of the effective time of the merger.

Indemnification and Insurance. The merger agreement provides that, for a period of six years after the merger, Macromedia, as the surviving corporation in the merger, will observe, to the fullest extent permitted by Delaware law, all rights of the directors and officers of Macromedia as of April 17, 2005 to indemnification for acts and omissions as directors and officers of Macromedia occurring before the effective time of the merger, as provided in the Macromedia certificate of incorporation and bylaws (as in effect on April 17, 2005) and in indemnification agreements with Macromedia as in effect on April 17, 2005 or, subject to certain conditions, entered into prior to the consummation of the merger. In addition, the merger agreement provides that for a period of six years after the merger, the surviving corporation will maintain in effect a directors' and officers' liability insurance policy for the benefit of the persons who were directors and officers of Macromedia as of April 17, 2005 with respect to their acts or omissions as directors and officers of Macromedia prior to the effective time of the merger with coverage comparable to the coverage under Macromedia's existing policy as of April 17, 2005, provided directors' and officers' liability insurance coverage is available for Adobe's directors and officers. If the annual premiums payable for such insurance coverage exceed 200% of the annual premium paid by Macromedia in 2004 for its existing policy, the surviving corporation may reduce the amount of coverage to the amount of coverage available for a cost equal to that amount.

Accelerated Vesting of Non-Employee Directors' Options. Pursuant to the terms of the Macromedia 2002 Equity Incentive Plan, upon the consummation of the merger, each non-employee director of Macromedia will be entitled to accelerated vesting of all unvested options to purchase Macromedia common stock then held by such non-employee director, issued pursuant to this plan. Charles M. Boesenberg, John (Ian) Giffen, Steven Gomo, William H. Harris, Jr., Donald L. Lucas, Timothy O'Reilly and William B. Welty are members of the Macromedia board who are not employees of Macromedia. As of July 1, 2005, Mr. Boesenberg held unvested options to purchase 49,997 shares of Macromedia common stock, Mr. Giffen held unvested options to purchase 41,667 shares of Macromedia common stock, Mr. Gomo held unvested options to purchase 37,497 shares of Macromedia common stock, Mr. Harris held unvested options to purchase 1,458 shares of Macromedia common stock, Mr. Lucas held unvested options to purchase 47,292 shares of Macromedia common stock, Mr. O'Reilly held unvested options to purchase 21,665 shares of Macromedia common stock and Mr. Welty held unvested options to purchase 42,709 shares of Macromedia common stock.

Employment Agreements. Macromedia and Adobe have entered into the following employment agreements with executive officers of Macromedia.

Robert K. Burgess Amended Employment Agreement

Macromedia entered into an employment agreement with Mr. Burgess on January 10, 2003. On January 19, 2005, this agreement was amended and restated in order to reflect the Macromedia board of directors' determination that Stephen Elop should become the Chief Executive Officer of Macromedia and Mr. Burgess should remain as Executive Chairman of Macromedia. Under the terms of the amended employment agreement, Mr. Burgess' annual base salary is $400,000 and his annual target bonus was $400,000 for the year ended March 31, 2005. Macromedia also agreed to purchase a $10 million term life insurance policy for Mr. Burgess, with the proceeds payable to a beneficiary designated by him, and, during his employment, to pay all premiums on such policy and to pay Mr. Burgess a gross-up for state and federal income taxes attributable to the payment of such

premiums. In July 2005, pursuant to the agreement and at the request of Mr. Burgess, Macromedia's compensation committee of the board of directors reduced Mr. Burgess' annual base salary from $400,000 to $100,000 and cancelled his annual bonus for fiscal year 2006. Both changes are effective as of July 1, 2005.

Mr. Burgess' amended employment agreement provides that, in the event that Mr. Burgess' employment with Macromedia is terminated

•: by Macromedia without cause,
•: because of his death or disability or
•: voluntarily by Mr. Burgess for good reason (which includes a material adverse change in his position, an involuntary reduction in his compensation by more than 10%, a relocation of his principal place of employment by more than 50 miles, or Macromedia's breach of its life insurance or indemnification obligations),

then upon the exchange of general releases by Mr. Burgess and Macromedia, Mr. Burgess will receive a lump sum payment, subject to tax withholding, equal to the greater of $1,600,000 and an amount equal to two times the sum of his annual base salary and his annual bonus at the level in effect immediately prior to his termination. Mr. Burgess' amended employment agreement provides that Macromedia will also reimburse Mr. Burgess for any expenses incurred by him and his dependents for the two-year period following his termination date, for coverage under the Consolidated Omnibus Budget Reconciliation Act of 1975, as amended, or COBRA, or pay for comparable coverage. Mr. Burgess' amended employment agreement provides that Macromedia will also pay the full annual premium and related tax gross-up on Mr. Burgess' life insurance policy for the contract year in which his employment with Macromedia is terminated. Mr. Burgess' amended employment agreement provides that Mr. Burgess will also be entitled to participate in any of Macromedia's plans or other employee benefit arrangements during the two-year period following termination, other than tax-qualified pension or profit-sharing plans or the employee stock purchase plan. In addition, the vesting of each of the options granted to Mr. Burgess prior to January 19, 2005 and outstanding at the time of termination will accelerate with respect to a number of shares equal to the greater of

•: the number of shares that would otherwise become vested over the 24-month period following the date of his termination of employment reduced by the number of months elapsed from the respective grant date of the option to his date of termination, or
•: the number of shares that would otherwise become exercisable during the 12-month period following the termination date,

provided that the vesting of any option granted to Mr. Burgess prior to January 19, 2005 with an exercise price less than the fair market value of a share of Macromedia common stock on January 19, 2005 will be accelerated by no less than 24 months. Options granted before January 10, 2003 will be exercisable until the end of the 180-day period following the later of the date 12 months after Mr. Burgess' termination date, or the date 24 months from the grant date of the option, or if earlier, the expiration date of the option; provided that any option granted to Mr. Burgess prior to January 10, 2003 with an exercise price less than the fair market value of a share of Macromedia common stock on January 10, 2003 will remain exercisable until the earlier of the end of the 180-day period following the date 24 months after his termination, or the expiration date of the option. Options granted after January 10, 2003 but before January 19, 2005 will be exercisable until the earlier of the end of the 180-day period following the date 24 months following Mr. Burgess' termination date, or the expiration date of the option. In addition, the vesting of any options granted to Mr. Burgess following January 19, 2005 and outstanding at the time of termination will accelerate upon such termination by no less than 24 months, and will remain exercisable until the earlier of one year following his termination date and the expiration date of such options.

Mr. Burgess' amended employment agreement provides that, in the event of a change of control of Macromedia, which the merger will constitute for this purpose, if

•: Mr. Burgess terminates his employment for any reason no later than 180 days following such change of control or
•: Mr. Burgess' employment is terminated no later than one year following such change of control by Macromedia without cause, because of his death or disability, or by Mr. Burgess for good reason,

then upon the exchange of general releases by Mr. Burgess and Macromedia, he will receive a lump sum equal to the greater of $1,600,000 and an amount equal to two times the sum of his annual base salary and his annual bonus at the level in effect immediately prior to his termination or prior to the change of control, if greater. Mr. Burgess' amended employment agreement provides that he will also be reimbursed for any expenses incurred by him and his dependents for the two-year period following his termination date, for coverage under COBRA or Macromedia will pay for comparable coverage. Mr. Burgess' amended employment agreement provides that Macromedia, or Macromedia's successor in the change of control, will also pay the full annual premium and related tax gross-up on Mr. Burgess' life insurance policy for the contract year in which his employment with Macromedia is terminated. Mr. Burgess will also be entitled to participate in any of Macromedia's or Macromedia's successor's plans or other employee benefit arrangements during such two-year period, other than tax-qualified pension or profit-sharing plans or the employee stock purchase plan, or Macromedia or its successor will provide comparable plans. Mr. Burgess' amended employment agreement provides that, in addition, all of Mr. Burgess' then outstanding options will immediately become exercisable and vest in full and will remain exercisable until the earlier of two years following his termination date and the expiration date of such options. Mr. Burgess' amended employment agreement also provides that all of Mr. Burgess' then outstanding restricted stock awards will vest in full, provided that Mr. Burgess must remain employed by Macromedia or its successor for up to six months following the change of control, if requested to do so in writing, in order to be entitled to the accelerated vesting of his restricted stock awards upon Mr. Burgess' termination of his employment for good reason.

Stephen A. Elop Employment Agreements

Agreement with Macromedia

Macromedia entered into an employment agreement with Mr. Elop in January 2005 in order to reflect the Macromedia board of directors' determination that Mr. Elop should become the Chief Executive Officer of Macromedia and Mr. Burgess should remain as Executive Chairman of Macromedia.

In addition, Mr. Elop's employment agreement provides that the vesting of any portion of the New Option that is outstanding at the time of termination will accelerate with respect to a number of shares equal to the number of shares that would otherwise become vested over the 12-month period following the date of his termination of employment and such options will be exercisable until the earlier of the one-year anniversary of the termination of his employment and the expiration date of the New Option.

Agreement with Adobe

Adobe has entered into an employment agreement with Mr. Elop to serve as its President of Worldwide Field Operations beginning upon the consummation of the merger, the terms of which are as follows:

Under the terms of the amended and restated contract, Mr. Elop's base salary will be $500,000 per year, and his target annual bonus will be $375,000, based on attainment of Adobe objectives. In addition, Mr. Elop will be eligible to participate in both the Adobe profit sharing plan (which can result in a payment to Mr. Elop of up to 10% of his annual base salary based on attainment of Adobe targets) and the Adobe Executive Severance Plan in the Event of a Change of Control of Adobe. Mr. Elop will also be granted an option to purchase 175,000 shares of Adobe common stock. Under the employment agreement, Adobe will reimburse Mr. Elop for his reasonable expenses in traveling between his office at corporate headquarters and his residence in Canada.

The amended and restated contract also confirms that upon the consummation of the merger, pursuant to resolutions adopted by the Macromedia compensation committee on February 26, 1997 and April 8, 2005, stock options awarded to Mr. Elop by Macromedia before January 19, 2005 will have vesting accelerated by an 18-month period.

In the event Mr. Elop's employment with Adobe is terminated by Adobe without cause, as a result of Mr. Elop's death or disability, or by Mr. Elop for good reason at or before the first anniversary of the day after the consummation of the merger, upon his providing a general release to Adobe, he will be entitled to receive a lump sum payment equal to the greater of $800,000 and an amount equal to the sum of his annual base salary and his annual bonus at the level in effect immediately prior to his termination, or if greater, immediately prior to the closing. He will also be reimbursed for any expenses incurred by him and his dependents for the one-year period following his termination date, for coverage under COBRA or Macromedia will pay for comparable coverage. In addition, and provided that any termination by Mr. Elop for good reason does not occur until the date 12 months after the closing of the acquisition of Macromedia by Adobe, the New Option and shares of restricted stock

granted to Mr. Elop by Macromedia in January 2005 will become fully vested and the New Option will remain exercisable until the earlier of the expiration date of such options and the first anniversary of his termination date. Each other option, including the Adobe option for 175,000 shares, will remain exercisable until the earlier of the expiration date of such options and the end of the period specified in the stock option agreements.

In the event Mr. Elop's employment with Adobe is terminated by Adobe without cause, as a result of Mr. Elop's death or disability, or by Mr. Elop for good reason after the day following the one year anniversary of the consummation of the merger, upon his providing a general release to Adobe, he will be entitled to receive a lump sum payment equal to the greater of $800,000 and an amount equal to the sum of his annual base salary and his annual bonus at the level in effect immediately prior to his termination.

In addition, options granted to Mr. Elop by Macromedia in January 2005 will have their vesting schedules accelerated by 12 months and will remain exercisable until the earlier of the one-year anniversary of the termination date, and the expiration date specified in the stock option agreement.

Under the agreement, good reason is defined as either: a termination by Mr. Elop, as a result of a material adverse change in his position as President of Worldwide Field Operations, an involuntary reduction in his compensation by more than 10%, a relocation of his principal place of employment by more than 50 miles or a material breach by Adobe of its indemnification obligations to Mr. Elop, or voluntary termination by Mr. Elop for any reason during the six-month period ending on the one year anniversary of the day after the consummation of the merger.

Also, in the event Mr. Elop's employment is terminated by Mr. Elop for any reason within 12 months after the day after the closing of the acquisition of Macromedia by Adobe, by Mr. Elop for any reason after January 19, 2007, by Adobe at any time without cause, as a result of Mr. Elop's death or disability, or by Mr. Elop for good reason, he will be entitled to an additional payment equal to $5,000,000 which will be reduced by

•: any gain Mr. Elop receives as a result of the sale, prior to his termination date, of shares attributable to any stock options exercised by Mr. Elop or any stock award granted to Mr. Elop including options granted to Mr. Elop pursuant to his employment agreement with Adobe;
•: the difference between the fair market value of any exercised but unsold shares and any unexercised vested shares (including shares that become vested as a result of the termination of employment and shares granted by Adobe under Mr. Elop's employment agreement with Adobe) attributable to any stock option granted to Mr. Elop and the exercise price of the applicable stock option; and
•: the fair market value of vested shares of restricted stock still held by Mr. Elop as of the termination date (including shares that become vested as a result of the termination of employment and shares granted by Adobe under Mr. Elop's employment agreement with Adobe).

The employment agreement also provides that Mr. Elop will sign a general release in order to receive the additional payment upon his voluntary termination other than for good reason within 12 months after the consummation of the merger.

In the event Mr. Elop remains an employee of Adobe until at least the one-year anniversary of the consummation of the merger, he will receive a payment of $1,000,000 from Adobe within 15 days of such anniversary date. If Mr. Elop's employment is terminated by Adobe without cause during the six-month period ending on the one-year anniversary of the consummation of the merger, Mr. Elop will be entitled to a pro rated payment equal to one-sixth of the total amount for each full or partial month

Mr. Elop remains employed by Adobe during the six-month period ending on the one-year anniversary of the consummation of the merger, to be paid within 15 days of the involuntary termination date.

Elizabeth A. Nelson Employment Agreement

Macromedia entered into an employment agreement with Ms. Nelson in January 2005 to retain her continued services as Executive Vice President, Chief Financial Officer and Secretary of Macromedia. Under the terms of the employment agreement, Ms. Nelson's annual base salary is $300,000 and her annual target bonus is $150,000 based on Macromedia objectives.

Ms. Nelson's employment agreement provides that Macromedia will also reimburse Ms. Nelson for any expenses incurred by her and her dependents for the one-year period following her termination date for coverage under COBRA or Macromedia will pay for comparable coverage. In addition, Ms. Nelson's employment agreement provides that the vesting of any equity compensation awards granted to Ms. Nelson following January 19, 2005 and outstanding at the time of her termination of employment will accelerate upon such termination by 12 months, and will remain exercisable until the earlier of one year following her termination date and the expiration date of such options.

Ms. Nelson's employment agreement provides that, in the event of a change of control of Macromedia, which the merger will constitute for this purpose, and within the 12-month period following the change of control, Ms. Nelson's employment with Macromedia is terminated

She will also be reimbursed for any expenses incurred by her and her dependents for the one-year period following her termination date for coverage under COBRA or Macromedia will pay for comparable coverage. In addition, Ms. Nelson's employment agreement provides that any equity compensation awards granted to Ms. Nelson after January 19, 2005 will immediately become 100% vested and any such stock options will remain exercisable until the earlier of one year following her termination date and the expiration date of such awards, provided that Ms. Nelson must remain employed by Macromedia or its successor for up to six months following the change of control, if requested to do so in writing, in order to be entitled to the accelerated vesting of her equity compensation awards upon Ms. Nelson's termination of her employment as a result of the occurrence

of a material adverse change in her position, an involuntary reduction in her compensation by more than 10%, a relocation of her principal place of employment by more than 50 miles, or Macromedia's breach of its indemnification obligations.

Thomas Hale, Kevin Lynch, David Mendels and Al Ramadan Offer Letters with Adobe

Mr. Hale, Senior Vice President and General Manager of Macromedia, Mr. Lynch, Executive Vice President, General Manager and Chief Software Architect of Macromedia, Mr. Mendels, Executive Vice President and General Manager of Macromedia, and Mr. Ramadan, Executive Vice President and General Manager of Mobile Devices of Macromedia have entered into offer letters with Adobe.

Change of Control Arrangements. Macromedia has entered into the following additional change of control arrangements with its executive officers, which will be triggered by the merger.

Elizabeth A. Nelson

Pursuant to a resolution adopted by the Macromedia board of directors in fiscal year 1998, if

•: upon or at any time after a change of control of Macromedia, which the merger will constitute for this purpose, there is a "constructive termination" of Ms. Nelson's employment as the Chief Financial Officer of Macromedia or
•: within one year following a change of control of Macromedia, there is a voluntary termination of her employment as the Chief Financial Officer of Macromedia,

Ms. Nelson is entitled to receive full vesting of any outstanding but unexercised options and/or other equity incentive awards granted prior to January 19, 2005, with such options and other equity incentive awards exercisable within 180 days from the date of such termination. A constructive termination is deemed to have occurred in the event of

•: a material adverse change in Ms. Nelson's position causing such position to be of materially less stature or responsibility without Ms. Nelson's consent,
•: a reduction in Ms. Nelson's compensation by more than 10% without her consent, or
•: relocation of the principal place of her employment by more than 50 miles.

Other Executive Officers of Macromedia

Pursuant to resolutions adopted by the Macromedia compensation committee on February 26, 1997 and April 8, 2005, stock options awarded to Stephen Elop, Thomas Hale, Kevin Lynch, David Mendels and Al Ramadan will have vesting accelerated by an 18-month period in the event of a change of control of Macromedia, which the merger will constitute for this purpose.

David Bernstein, Vice President, Finance of Macromedia, has an agreement with Macromedia, which was affirmed by the Macromedia compensation committee on April 8, 2005, that provides for 12 months of accelerated vesting of his options upon a change of control of Macromedia, which the merger will constitute for this purpose. In the event that his employment is involuntarily terminated as

a result of a change of control of Macromedia, which the merger will constitute for this purpose, Mr. Bernstein will receive an amount equal to six months of his average compensation.

Noncompetition Agreements. In connection with the merger, Adobe and Macromedia entered into noncompetition agreements with Messrs. Burgess, Elop, Hale, Lynch, Mendels and Ramadan. Under the terms of the noncompetition agreements, Messrs. Burgess, Elop, Hale, Lynch, Mendels and Ramadan agreed, among other things and subject to certain exceptions, not to, directly or indirectly, engage in competition with respect to Macromedia's products and services, each as further defined in the agreement, at any time within two years following the effective time of the merger, within the United States and certain other countries and territories. Messrs. Burgess, Elop, Hale, Lynch, Mendels and Ramadan further agreed, subject to certain exceptions, to not directly or indirectly, solicit, attempt to solicit, induce or attempt to induce any person or entity to terminate their employment or other relationship with Adobe or any of its affiliates.

In addition, the non-competition agreements with Messrs. Hale, Lynch and Mendels provide that each person's applicable non-competition agreement shall not become effective unless:

•: prior to the effective time of the merger Messrs. Hale, Lynch and Mendels have been granted new stock options to purchase 125,000, 175,000, 125,000 shares of Macromedia common stock, respectively; or
•: within 10 days after the consummation of the merger, such applicable person has either been granted materially equivalent stock options to purchase shares of Adobe common stock or been provided with shares of Adobe common stock equal in value to the value of such Macromedia stock options.

Material Federal Income Tax Consequences

The following discussion summarizes the material U.S. federal income tax considerations of the merger that are expected to apply generally to Macromedia stockholders upon an exchange of their Macromedia common stock for Adobe common stock in the merger. This summary is based upon current provisions of the Code, existing regulations under the Code and current administrative rulings and court decisions, all of which are subject to change. Any change, which may or may not be retroactive, could alter the tax consequences to Adobe, Macromedia or the stockholders of Macromedia as described in this summary. In addition, this summary assumes the truth and satisfaction of the statements and conditions described below as the basis for the tax opinions of Cooley Godward LLP, tax counsel to Adobe, and Fenwick & West LLP, tax counsel to Macromedia. No attempt has been made to comment on all U.S. federal income tax consequences of the merger that may be relevant to particular holders, including holders:

•: who are subject to special tax rules such as dealers in securities, foreign persons, mutual funds, regulated investment companies, real estate investment trusts, insurance companies or tax-exempt entities;
•: who are subject to the alternative minimum tax provisions of the Code;
•: who acquired their shares in connection with stock option or stock purchase plans or in other compensatory transactions;
•: who hold their shares as a hedge or as part of a hedging, straddle or other risk reduction strategy; or
•: who do not hold their shares as capital assets.

In addition, the following discussion does not address the tax consequences of the merger under state, local and foreign tax laws. Furthermore, the following discussion does not address any of the following:

•: the tax consequences of transactions effectuated before, after or at the same time as the merger, whether or not they are in connection with the merger, including, without limitation, transactions in which Macromedia shares are acquired or Adobe shares are disposed of;
•: the tax consequences to holders of options issued by Macromedia which are assumed, replaced, exercised or converted, as the case may be, in connection with the merger;
•: the tax consequences of the receipt of Adobe shares other than in exchange for Macromedia shares; or
•: the tax implications of a failure of the merger to qualify as a reorganization.

Accordingly, holders of Macromedia common stock are advised and expected to consult their own tax advisors regarding the federal income tax consequences of the merger in light of their personal circumstances and the consequences of the merger under state, local and foreign tax laws.

As a condition to the consummation of the merger, Cooley Godward LLP and Fenwick & West LLP must render tax opinions that the merger will constitute a reorganization within the meaning of Section 368 of the Code, or a Reorganization. The tax opinions discussed in this section are conditioned upon certain assumptions stated in the tax opinions and the tax representations made by Macromedia and Adobe.

No ruling from the Internal Revenue Service has been or will be requested in connection with the merger. In addition, stockholders of Macromedia should be aware that the tax opinions discussed in this section are not binding on the IRS, the IRS could adopt a contrary position and a contrary position could be sustained by a court.

Subject to the assumptions and limitations discussed above, it is the opinion of Cooley Godward LLP and Fenwick & West LLP that the merger will be treated for U.S. federal income tax purposes as a Reorganization. Accordingly, if the merger is treated for U.S. federal income tax purposes as a Reorganization,

•: Adobe, Merger Sub and Macromedia will each be a party to the Reorganization;
•: Adobe, Merger Sub and Macromedia will not recognize any gain or loss solely as a result of the merger;
•: stockholders of Macromedia will not recognize any gain or loss upon the receipt of solely Adobe common stock for their Macromedia common stock, other than with respect to cash received in lieu of fractional shares of Adobe common stock;
•: the aggregate tax basis of the shares of Adobe common stock received by a Macromedia stockholder in the merger (including any fractional share deemed received) will be the same as the aggregate basis of the shares of Macromedia common stock surrendered in exchange therefor;
•: the holding period of the shares of Adobe common stock received by a Macromedia stockholder in the merger will include the holding period of the shares of Macromedia common stock surrendered in exchange therefor; and
•: cash payments received by Macromedia stockholders in lieu of fractional shares will be treated as if such fractional shares of Adobe common stock were issued in the merger and then sold. A stockholder of Macromedia who receives such cash will recognize gain or loss equal to the difference, if any, between such stockholder's basis in the fractional share and the amount of

cash received. Such gain or loss will be a capital gain or loss and any such capital gain will be long-term capital gain if the Macromedia common stock is held by such stockholder as a capital asset at the effective time of the merger and such stockholder's holding period for his, her or its Macromedia common stock is more than one year.

Macromedia stockholders are required to attach a statement to their tax returns for the year in which the merger is consummated that contains the information listed in Treasury Regulation Section 1.368-3(b). Such statement must include the stockholder's tax basis in the stockholder's Macromedia common stock and a description of the Adobe common stock received.

The preceding discussion is intended only as a summary of certain U.S. federal income tax consequences of the merger and does not purport to be a complete analysis or discussion of all of the merger's potential tax effects. Macromedia stockholders are urged to consult their own tax advisors as to the specific tax consequences to them of the merger, including tax return reporting requirements, and the applicability and effect of federal, state, local and other applicable tax laws.

Anticipated Accounting Treatment

The merger is expected to be accounted for using the purchase method of accounting pursuant to Statement of Financial Accounting Standards No. 141, Business Combinations. Under the purchase method of accounting, the total estimated purchase price is allocated to the net tangible and intangible assets of Macromedia acquired in connection with the merger, based on their estimated fair values. These allocations will be based upon a valuation that has not yet been finalized.

Appraisal Rights

Legal Proceedings Related to the Merger

On June 13, 2005, a shareholder derivative action entitled Steve Staehr, Derivatively on Behalf of Adobe Systems Incorporated v. Bruce R. Chizen, et. al., was filed in the Superior Court of the State of California for the County of Santa Clara against Adobe's directors and naming Adobe as a nominal defendant. The complaint alleges that the defendants breached their fiduciary duties of loyalty and due care and caused Adobe to waste corporate assets by failing to renegotiate or terminate the merger agreement following the announcement by Macromedia that it would restate its financial results for the fiscal years ended March 31, 1999 through 2004 and by failing to conduct sufficient due diligence prior to entering into the merger agreement. The complaint seeks, among other things, unspecified monetary damages, attorneys fees and certain forms of equitable relief, including preliminarily and permanently enjoining the consummation of the merger. Adobe has obligations under certain circumstances to hold harmless and indemnify each of the defendant directors against judgments, fines, settlements and expenses related to claims and otherwise to the fullest extent permitted under Delaware law and Adobe's bylaws and certificate of incorporation. Such obligations may apply to the lawsuit. Adobe's management believes that the allegations are without merit and intends to vigorously contest the action. However, there can be no assurance that the defendants will be successful in their defense.

Regulatory Approvals

To consummate the merger, Adobe and Macromedia must make filings with and obtain approvals or clearances from antitrust regulatory authorities. Transactions such as the merger are subject to review by the U.S. Department of Justice, or DOJ, and the Federal Trade Commission, or FTC, in the

United States, certain governmental entities in the European Union and other countries to determine whether they comply with applicable antitrust laws. Under the provisions of the HSR Act, the merger may not be consummated until the specified waiting period requirements of the HSR Act have been satisfied. Adobe and Macromedia filed notification reports, together with requests for early termination of the waiting period, with the DOJ and the FTC under the HSR Act on May 6, 2005. Adobe voluntarily withdrew its original notification report on June 6, 2005 and refiled on June 8, 2005. The refiling was a procedural step to provide the staff at the Antitrust Division of the DOJ with additional time to review the information submitted by Adobe and Macromedia. On July 8, 2005, Adobe and Macromedia each received a government request for additional information and documentary material, or a second request. Both of the second requests were limited to information about the companies' products in the areas of web authoring/design and vector graphics illustration. The second requests will extend the waiting period imposed by the HSR Act until 30 days after Adobe and Macromedia have substantially complied with the requests. In the United States, Adobe must also comply with applicable federal and state securities laws and the rules and regulations of The Nasdaq Stock Market, Inc. in connection with the issuance of shares of Adobe common stock in the merger and the filing of this joint proxy statement/prospectus with the SEC.

Restrictions on Resales

The shares of Adobe common stock to be received by Macromedia stockholders in the merger will be registered under the Securities Act of 1933 and, except as described in this section, may be freely traded without restriction. Adobe's registration statement on Form S-4, of which this joint proxy statement/prospectus forms a part, does not cover the resale of shares of Adobe common stock to be received in connection with the merger by persons who are deemed to be "affiliates" of Macromedia on the date of the Macromedia special meeting of stockholders. The shares of Adobe common stock to be issued in the merger and received by persons who are deemed to be "affiliates" of Macromedia on the date of the Macromedia special meeting of stockholders may be resold by them only in transactions permitted by the resale provisions of Rule 145 under the Securities Act of 1933 or as otherwise permitted under the Securities Act of 1933. Persons who are deemed to be "affiliates" of Macromedia prior to the merger include individuals or entities that control, are controlled by, or are under common control with Macromedia on the date of the Macromedia special meeting, and may include officers and directors, as well as principal stockholders, of Macromedia on the date of the Macromedia special meeting. Affiliates of Macromedia will be notified separately of their affiliate status.

The merger agreement provides that Macromedia will use commercially reasonable efforts to help Adobe obtain a signed affiliate agreement from each person who is, becomes or may be deemed to be an "affiliate" of Macromedia. The merger agreement provides that Adobe will not issue shares of Adobe common stock to any "affiliate" of Macromedia who has not provided Adobe with a signed affiliate agreement. The affiliate agreements provide, among other things, that these persons will not sell, transfer or otherwise dispose of their shares of Adobe common stock received in the merger at any time in violation of the Securities Act of 1933 or the rules and regulations promulgated under the Securities Act of 1933, including Rule 145.

Other than as described above in the section entitled "Interests of Macromedia's Executive Officers and Directors in the Merger," if any shares of Macromedia common stock outstanding immediately before the consummation of the merger are unvested or are subject to a repurchase option, risk of forfeiture or other condition (including restrictions on transfer) under any restricted stock purchase agreement or other contract, then the shares of Adobe common stock issued in exchange for such shares will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition.

THE MERGER AGREEMENT

The following description describes the material terms of the merger agreement. This description of the merger agreement is qualified in its entirety by reference to the full text of the merger agreement which is attached as Annex A to this joint proxy statement/prospectus and is incorporated herein by reference. The merger agreement has been included to provide you with information regarding its terms. We encourage you to read the entire merger agreement. The merger agreement is not intended to provide any other factual information about us. Such information can be found elsewhere in this joint proxy statement/prospectus and in the other public filings each of Adobe and Macromedia makes with the Securities and Exchange Commission, which are available without charge at www.sec.gov.

The Merger

The merger agreement provides that at the effective time, Avner Acquisition Sub, or Merger Sub, a wholly owned subsidiary of Adobe, will be merged with and into Macromedia. Upon the consummation of the merger, Macromedia will continue as the surviving corporation and will be a wholly owned subsidiary of Adobe.

Effective Time of the Merger

The merger agreement requires the parties to consummate the merger after all of the conditions to the consummation of the merger contained in the merger agreement are satisfied or waived, including the adoption of the merger agreement by the stockholders of Macromedia and the approval of the issuance of shares of Adobe common stock in the merger by the stockholders of Adobe. The merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware or at such later time as is agreed by Adobe and Macromedia and specified in the certificate of merger. Because the consummation of the merger is subject to the receipt of governmental and regulatory approvals and the satisfaction of other conditions, we cannot predict the exact timing of the consummation of the merger.

Manner and Basis of Converting Shares

At the effective time, each share of Macromedia common stock will automatically be converted into the right to receive 1.38 shares of Adobe common stock. This number is referred to in this joint proxy/prospectus as the exchange ratio and is subject to future adjustment for stock splits, recapitalizations, reclassifications or other similar changes occurring prior to the consummation of the merger (other than the Adobe stock split referenced above).

No fractional shares of Adobe common stock will be issued in the merger. Instead, each Macromedia stockholder otherwise entitled to a fraction of a share of Adobe common stock (after aggregating all fractional shares of Adobe common stock issuable to such stockholder) will be entitled to receive in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing price of a share of Adobe common stock on the NASDAQ National Market on the date the merger becomes effective.

The merger agreement provides that, prior to the effective time of the merger, Adobe will select a bank or trust company to act as the exchange agent under the merger agreement. The merger agreement provides that promptly after the effective time of the merger, Adobe will deposit with the exchange agent stock certificates representing the shares of Adobe common stock issuable in exchange

for shares of Macromedia common stock and a sufficient amount of cash to make payments in lieu of fractional shares.

The merger agreement contemplates that, as promptly as practicable following the effective time of the merger, the exchange agent for the merger will mail to each record holder of Macromedia common stock immediately prior to the effective time of the merger a letter of transmittal and instructions for surrendering and exchanging the record holder's Macromedia stock certificates. The merger agreement provides that, upon surrender of a Macromedia common stock certificate for exchange to the exchange agent, together with a duly signed letter of transmittal, and such other documents as the exchange agent or Adobe may reasonably require, the holder of the Macromedia stock certificate will be entitled to receive the following:

•: a certificate representing Adobe common stock,
•: cash in lieu of any fractional share of Adobe common stock, and
•: any dividends or other distributions declared or made with respect to Adobe common stock with a record date after the effective time of the merger and a payment date prior to the date the Macromedia stock certificate was surrendered.

The stock certificate so surrendered will be cancelled.

After the effective time of the merger, all holders of certificates representing shares of Macromedia common stock that were outstanding immediately prior to the effective time of the merger will cease to have any rights as stockholders of Macromedia. In addition, no transfer of Macromedia common stock after the effective time of the merger will be registered on the stock transfer books of Macromedia.

If any Macromedia stock certificate has been lost, stolen or destroyed, Adobe may in its reasonable discretion, and as a condition to the issuance of any certificate representing Adobe common stock in exchange therefor, require the owner of such certificate to deliver an affidavit claiming such certificate has been lost, stolen or destroyed and post a bond in such amount as Adobe may reasonably direct as indemnity against any claim that may be made with respect to that certificate against Adobe, the surviving corporation or the exchange agent.

From and after the effective time of the merger, until it is surrendered and exchanged, each certificate that previously evidenced Macromedia common stock will be deemed to represent only the right to receive shares of Adobe common stock and cash in lieu of any fractional share of Adobe common stock. Adobe will not pay dividends or other distributions on any shares of Adobe common stock to be issued in exchange for any unsurrendered Macromedia common stock certificate until the Macromedia common stock certificate is surrendered as provided in the merger agreement.

Stock certificates should not be surrendered for exchange by Macromedia stockholders before the effective time of the merger and should be sent only pursuant to instructions set forth in the letters of transmittal which the merger agreement provides will be mailed to Macromedia stockholders as promptly as practicable following the effective time of the merger. In all cases, the certificates representing shares of Adobe common stock and cash in lieu of fractional shares will be delivered only in accordance with the procedures set forth in the letter of transmittal.

The merger agreement contemplates that, upon demand by Adobe, the exchange agent will deliver to Adobe any certificates representing Adobe common stock and any funds which have not been disbursed to holders of Macromedia stock certificates as of 180 days after the effective time of the merger. Any holders of Macromedia stock certificates who have not surrendered such certificates in compliance with the above-described procedures may thereafter look only to Adobe for certificates representing shares of Adobe common stock, cash in lieu of fractional shares and any dividends or distributions with respect to such Adobe common stock.

Representations and Warranties

The merger agreement contains customary representations and warranties that Adobe and Macromedia made to, and solely for the benefit of, each other. The representations and warranties in the merger agreement expire at the effective time of the merger. The assertions embodied in those representations and warranties are qualified by information in confidential disclosure schedules that Adobe and Macromedia have exchanged in connection with signing the merger agreement. While Adobe and Macromedia do not believe that these disclosure schedules contain information securities laws require the parties to publicly disclose other than information that has already been so disclosed, they do contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the merger agreement. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts, since they were only made as of the date of the merger agreement and are modified in important part by the underlying disclosure schedules. These disclosure schedules contain information that has been included in the companies' general prior public disclosures, as well as additional non-public information. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the merger agreement, which subsequent information may or may not be fully reflected in the companies' public disclosures.

Covenants; Conduct of Business Prior to the Merger

Affirmative Covenants of Macromedia. Macromedia has agreed that before the effective time of the merger, it will, and in certain cases, it will cause its subsidiaries to:

•

provide Adobe and its representatives with reasonable access during normal business hours to its personnel, representatives, assets, books, records, tax returns and other documents;

•

conduct its business and operations in the ordinary course and in accordance with past practices, use its commercially reasonable efforts to conduct its business and operations in material compliance with applicable legal requirements and the requirements of all significant contracts to which Macromedia is a party or by which it is bound, use its commercially reasonable efforts to attempt to ensure that Macromedia preserves intact the material components of its current business organization, keeps available the services of its current officers and other key employees and maintains its relations with its material suppliers, material customers, material licensors, material licensees and governmental bodies;

•

promptly notify Adobe of any claim or legal proceeding relating to the transactions contemplated by the merger agreement commenced or, to Macromedia's knowledge, overtly threatened by a governmental body or threatened in writing by any other person;

•

promptly notify Adobe of:

•

the discovery of any event, condition, fact or circumstance that occurred or existed on or prior to the date of the merger agreement and that caused or constitutes a material inaccuracy in any representation or warranty made by Macromedia;

•

any event, condition, fact or circumstance that occurs, arises or exists after the date of the merger agreement and that would cause or constitute a material inaccuracy in any representation or warranty made by Macromedia if:

•: such representation or warranty had been made as of the time of such occurrence, existence or discovery or
•: such event, condition, fact or circumstance had occurred, arisen or existed as of the date of the merger agreement;

•: any material breach of any covenant or obligation of Macromedia set forth in the merger agreement; or
•: any event, condition, fact or circumstance that would make the timely satisfaction of any of the conditions to Adobe's obligation to consummate the merger impossible or unlikely or would reasonably be expected to have or result in a material adverse effect on Macromedia;

•: at the request of Adobe, take such action so as to cause the termination of Macromedia's 401(k) plans no less than one day prior to the effective time of the merger;
•: use commercially reasonable efforts to cause to be delivered to Adobe a letter of KPMG LLP, dated within two days before the date on which the Form S-4 registration statement of which this joint proxy statement/prospectus is a part became effective, that is customary in scope and substance for letters delivered by independent public accountants in connection with registration statements similar to the Form S-4 registration statement (and reasonably satisfactory in form and substance to Adobe);
•: use its commercially reasonable efforts to cause certain stockholders of Macromedia to enter into affiliate agreements with Adobe; and
•: use its reasonable best efforts to rectify any material weakness (or series of control deficiencies that collectively are deemed to constitute a material weakness) in the effectiveness of Macromedia's internal control over financial reporting that is identified by Macromedia or its auditors.

Negative Covenants of Macromedia. Macromedia has agreed that before the effective time of the merger, except as otherwise consented to in writing by Adobe, which consent in some cases may not be unreasonably withheld, or as previously disclosed to Adobe pursuant to the merger agreement, it will not, will not agree to, and will not permit any of its subsidiaries to:

•: declare, accrue, set aside or pay any dividend or make any other distribution in respect of any shares of capital stock, or repurchase, redeem or otherwise reacquire any shares of capital stock or other securities, other than pursuant to Macromedia's right to repurchase restricted shares;
•: subject to limited exceptions, sell, issue, grant or authorize the sale, issuance or grant of any capital stock or other security or any option, call, warrant or right to acquire any capital stock or other security;
•: subject to limited exceptions, amend or waive any of its rights under, or accelerate the vesting under, any provision of Macromedia's stock option plans, any agreement evidencing any outstanding stock option or any restricted stock purchase agreement or otherwise modify the terms of any outstanding stock option or other security or related contract;
•: amend, terminate or grant any waiver under Macromedia's stockholder rights agreement;

Affirmative Covenants of Adobe. Adobe has agreed that before the effective time of the merger, it will:

•: use commercially reasonable efforts to cause the shares of Adobe common stock to be issued in the merger to be approved for listing on the NASDAQ National Market;
•: cause Merger Sub to perform its obligations under the merger agreement;
•: cause Robert K. Burgess to be elected or appointed to the board of directors of Adobe as of the effective time of the merger;
•: use its reasonable best efforts to rectify any material weakness (or a series of control deficiencies that collectively are deemed to be a material weakness) in the effectiveness of Adobe's internal control over financial reporting that is identified by Adobe or its auditors; and

•

promptly notify Macromedia of:

•

•: such representation or warranty had been made as of the time of such occurrence, existence or discovery or
•: such event, condition, fact or circumstance had occurred, arisen or existed as of the date of the merger agreement;

•

any material breach of any covenant or obligation of Adobe or Merger Sub set forth in the merger agreement; or

•

any event, condition, fact or circumstance that would make the timely satisfaction of any of the conditions to Macromedia's obligation to consummate the merger impossible or unlikely or would reasonably be expected to have or result in a material adverse effect on Adobe.

Negative Covenants of Adobe. Adobe has agreed that before the effective time of the merger, it will not, except as consented to by Macromedia:

•: subject to limited exceptions, declare, accrue, set aside or pay any cash dividend or make any other distribution in respect to any shares of stock;
•: subject to limited exceptions, amend or permit the adoption of any amendment to its certificate of incorporation or bylaws;

•: acquire or agree to acquire by merging or consolidating with, or by purchasing any controlling equity interest in, or all or substantially all of the assets of, any business, corporation, partnership, association or other business organization or division thereof for consideration in excess of $100 million if the acquisition presents a material risk of materially delaying the effectiveness of the merger or making it materially more difficult to obtain any consents necessary to consummate the merger, without consulting with Macromedia and considering the views and comments of Macromedia with regard to such risk of delay or increased difficulty in obtaining such consents; or
•: subject to limited exceptions, take any action that would be reasonably expected to cause the merger to fail to qualify as a "reorganization" for federal income tax purposes under the Code.

Affirmative Covenants of Adobe and Macromedia. Both Adobe and Macromedia have agreed that:

•: as promptly as practicable after the date of the merger agreement, both Adobe and Macromedia will prepare and cause to be filed with the SEC a registration statement on Form S-4, of which this joint proxy statement/prospectus is a part, to use commercially reasonable efforts to cause the registration statement to be declared effective as promptly as practicable after it is filed with the SEC, and to keep such registration statement effective through the consummation of the merger in order to permit the consummation of the merger;

•: each party will use commercially reasonable efforts to file, as soon as practicable after the date of the merger agreement, all notices, reports and other documents required to be filed with any governmental body, including all notifications and responses to requests for additional information required under the HSR Act and any applicable foreign antitrust laws or regulations in connection with the merger and the other transactions contemplated by the merger agreement;
•: each party will use its reasonable best efforts to contest, resist or resolve any administrative or judicial proceeding challenging the merger as violative of any antitrust laws and have any injunction resulting from any such administrative or judicial proceeding vacated, lifted, reversed or overturned; and
•: each party will use commercially reasonable efforts to take, or cause to be taken, all actions necessary to consummate the merger and the other transactions contemplated by the merger agreement.

Macromedia Stock Options

The merger agreement provides that, at the effective time of the merger, each Macromedia stock option that is outstanding and unexercised immediately prior to the effective time of the merger, whether or not vested, will be converted into an option to purchase Adobe common stock and Adobe will either assume such stock option or will replace such stock option by issuing a materially equivalent replacement stock option to purchase Adobe common stock in accordance with the terms of the applicable Macromedia stock option plan and terms of the stock option agreement relating to that Macromedia stock option. However, Adobe has the right, subject to certain conditions, to not assume or replace stock options to purchase up to 28,251 shares of Macromedia common stock issued pursuant to certain Macromedia stock option plans under which all outstanding options have already vested in full. In the event Adobe chooses not to assume or replace such stock options, the terms of the relevant stock option plans provide that they will terminate at the effective time of the merger if not exercised prior thereto. The number of shares of Adobe common stock subject to each assumed or replaced Macromedia stock option will be determined by multiplying the number of shares of Macromedia common stock subject to the stock option immediately prior to the effective time of the merger by the exchange ratio (rounding down to the nearest whole number of shares of Adobe common stock). The per share exercise price for shares of Adobe common stock under each assumed or replaced Macromedia stock option will be determined by dividing the exercise price for the Macromedia common stock subject to the stock option immediately prior to the effective time of the merger by the exchange ratio and rounding up to the nearest whole cent. After adjusting the assumed or replaced stock options to reflect the application of the exchange ratio, all other terms of the assumed or replaced stock options, including the term, exercisability and vesting schedule, will remain unchanged, except that Adobe's board of directors or a committee thereof will succeed to the authority and responsibility of Macromedia's board of directors or a committee thereof with respect to such stock options. Some holders of stock options to purchase Macromedia common stock will be entitled to full or partial acceleration of vesting of their outstanding Macromedia stock options upon the consummation of the merger. For more information as it relates to Macromedia's directors and executive officers, please see "The Merger—Interests of Macromedia's Executive Officers and Directors in the Merger."

Adobe has agreed to file a registration statement on Form S-8 within 15 days after the effective time of the merger for the shares of Adobe common stock issuable upon exercise of the assumed or replaced stock options. Adobe has agreed to use its commercially reasonable efforts to maintain the effectiveness of this registration statement so long as any assumed or replaced stock options remain outstanding.

Macromedia Employee Stock Purchase Plan

The merger agreement provides that Macromedia will terminate its 2003 Employee Stock Purchase Plan immediately prior to the effective time of the merger. The merger agreement provides that, upon Adobe's request, prior to the effective time of the merger, Macromedia will take all actions reasonably necessary to:

•: cause any outstanding offering period to be terminated as of the last business day before the effective date of the merger;
•: make any pro-rata adjustments that may be necessary to reflect the shortened offering period (but the offering period will otherwise be treated as a fully effective and completed offering period for all purposes of the 2003 Employee Stock Purchase Plan);
•: cause the exercise as of the last business day before the effective date of the merger of each purchase right under the 2003 Employee Stock Purchase Plan; and
•: provide that no further offering period or purchase period will commence under the 2003 Employee Stock Purchase Plan.

The merger agreement provides that, on the last business day before the effective date of the merger, Macromedia will apply the funds credited as of such date under the 2003 Employee Stock Purchase Plan within each participant's payroll withholding account to the purchase of whole shares of Macromedia common stock in accordance with the terms of the 2003 Employee Stock Purchase Plan. The termination of the 2003 Employee Stock Purchase Plan and the shortening of the offering period described above are conditioned upon the consummation of the merger.

Employee Benefits Matters

The merger agreement provides that, subject to any necessary transition period and subject to any applicable plan provisions, contractual requirements or legal requirements, employees of Macromedia (or its subsidiaries) who continue employment with Adobe (or its subsidiaries) after the effective time of the merger, who are sometimes referred to as continuing Macromedia employees, will be eligible to participate in:

•: Adobe's employee stock purchase plan and, as determined by Adobe, its applicable stock option plans,
•: Adobe's non-equity employee benefit plans and programs, including any profit-sharing plan, severance plan, medical plan, dental plan, life insurance plan, time-off programs and disability plan (in each case to substantially the same extent as similarly situated employees of Adobe), and
•: such employee benefit plans and programs of Macromedia that are continued by Macromedia after the consummation of the merger or that are assumed by Adobe.

The merger agreement provides that continuing Macromedia employees will (to the extent permitted by applicable legal requirements) receive credit for their continuous service with Macromedia (or its subsidiaries), as recognized by Macromedia, prior to the effective time of the merger, under Adobe's employee benefit plans (except for purposes of Adobe's sabbatical program and vesting of any Adobe stock options granted by Adobe after the consummation of the merger). In addition, the merger agreement provides that Adobe will waive eligibility requirements and/or pre-existing condition limitations (to the extent required by law) under its welfare benefits plans maintained for the benefit of continuing Macromedia employees located in the U.S. and will give effect to amounts previously paid by continuing Macromedia employees during the plan year in which the merger is consummated in

determining any deductible maximum out-of-pocket limitations under such welfare benefit plans (subject in each case to any applicable plan provisions, contractual requirements or legal requirements).

In addition, the merger agreement provides that, in the event that the commencement of the next regularly scheduled offering period under Adobe's employee stock purchase plan begins more than 90 days after the consummation of the merger, Adobe will establish a special offering period under its employee stock purchase plan for continuing Macromedia employees, which will begin as soon as administratively practicable following the consummation of the merger and which will end on the date immediately prior to the date of commencement of the next regularly scheduled offering period under the Adobe employee stock purchase plan.

Nothing provided for in the merger agreement creates a right in any Macromedia employee to employment with Adobe, the surviving corporation or any other subsidiary of Adobe. In addition, no Macromedia employee or employee who continues employment with Adobe will be deemed to be a third party beneficiary of the merger agreement, except for officers and directors of Macromedia to the extent of their respective rights with respect to the maintenance of indemnification rights and directors' and officers' liability insurance coverage. Please see "The Merger Agreement—Indemnification and Insurance."

Indemnification and Insurance

The merger agreement provides that, for a period of six years after the merger, the surviving corporation will observe, to the fullest extent permitted by Delaware law, all rights of the directors and officers of Macromedia as of April 17, 2005 to indemnification for acts and omissions as directors and officers of Macromedia occurring before the effective time of the merger, as provided in the Macromedia certificate of incorporation and bylaws (as in effect on April 17, 2005) and in indemnification agreements with Macromedia as in effect on April 17, 2005 or, subject to certain conditions, entered into prior to the consummation of the merger. In addition, the merger agreement provides that for a period of six years after the merger, the surviving corporation will maintain in effect a directors' and officers' liability insurance policy for the benefit of the persons who were the directors and officers of Macromedia as of April 17, 2005 with respect to their acts or omissions as directors and officers of Macromedia prior to the effective time of the merger with coverage comparable to the coverage under Macromedia's existing policy as of April 17, 2005, provided directors' and officers' liability insurance coverage is available for Adobe's directors and officers. If the annual premiums payable for such insurance coverage exceed 200% of the annual premium paid by Macromedia in 2004 for its existing policy, the surviving corporation may reduce the amount of coverage to the amount of coverage available for a cost equal to that amount.

Obligations of the Adobe Board of Directors and Macromedia Board of Directors with Respect to Their Recommendations and Holding Meetings of Stockholders

Both Macromedia and Adobe have agreed to take all action necessary to call, give notice of and, as promptly as practicable after the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part is deemed effective under the Securities Act of 1933, hold meetings of their respective stockholders, in the case of Macromedia, for the adoption of the merger agreement, and, in the case of Adobe, for the approval of the issuance of shares of Adobe common stock in the merger.

Both Macromedia and Adobe have agreed to include a statement in this joint proxy statement/prospectus to the effect that, in the case of Macromedia, the board of directors of Macromedia recommends that Macromedia's stockholders adopt the merger agreement at the Macromedia special meeting, and, in the case of Adobe, the board of directors of Adobe recommends that Adobe's stockholders approve the issuance of shares of Adobe common stock in the merger at the Adobe

special meeting. The merger agreement provides that neither the board of directors of Macromedia nor the board of directors of Adobe may withdraw its recommendation or modify its recommendation in a manner adverse to the other company except in certain circumstances. However, this provision does not preclude Macromedia or Adobe from making accurate and complete public disclosure of any material facts, including, in the case of Macromedia, a competing acquisition proposal, if the board of directors of that company determines in good faith, after taking into account the advice of its outside legal counsel, that such disclosure is required by fiduciary duties of that company's board of directors or by any legal requirement, and that company has given the other company reasonable advance notice of such disclosure. Moreover, the provision prohibiting the withdrawal or adverse modification of the recommendation of the Macromedia board of directors does not preclude Macromedia from complying with Rules 14d-9 and 14e-2 and Item 1012(a) of Regulation M-A under the Securities Exchange Act of 1934 with regard to any acquisition proposal that Macromedia may receive.

The merger agreement provides that Macromedia's board of directors is entitled to withdraw or modify its recommendation that Macromedia's stockholders vote to adopt the merger agreement if certain requirements, including the following, are met:

•: Macromedia satisfies certain notice requirements;
•: Macromedia's board of directors determines in good faith that Macromedia has received a superior offer that has not been withdrawn or that (i) a material adverse effect on Adobe has occurred since the date of the merger agreement and is continuing, or (ii) since the date of the merger agreement an event has occurred or circumstance exists that, in combination with any other events or circumstances since the date of the merger agreement, would reasonably be expected to have or result in a material adverse effect on Adobe; and
•: Macromedia's board of directors determines in good faith, after taking into account the advice of outside legal counsel, that the withdrawal or modification of its recommendation is required in order for Macromedia's board of directors to comply with its fiduciary obligations to Macromedia's stockholders under applicable law.

The merger agreement provides that Adobe's board of directors is entitled to withdraw or modify its recommendation that Adobe's stockholders vote to approve the issuance of shares of Adobe common stock in the merger if certain requirements, including the following, are met:

•: Adobe satisfies certain notice requirements;
•: Adobe's board of directors determines in good faith that (i) a material adverse effect on Macromedia has occurred since the date of the merger agreement and is continuing or (ii) since the date of the merger agreement an event has occurred or circumstance exists that, in combination with any other events or circumstances since the date of the merger agreement, would reasonably be expected to have or result in a material adverse effect on Macromedia; and
•: Adobe's board of directors determines in good faith, after taking into account the advice of outside legal counsel, that the withdrawal or modification of its recommendation is required in order for Adobe's board of directors to comply with its fiduciary obligations to Adobe's stockholders under applicable law.

The merger agreement provides that, if either company withdraws or modifies the recommendation of its board of directors, in the case of Macromedia, that Macromedia stockholders vote for the adoption of the merger agreement, and, in the case of Adobe, that Adobe stockholders vote for the issuance of shares of Adobe common stock in the merger and the merger agreement is subsequently terminated, that company may be required to pay a fee of $103.2 million to the other company. See "Expenses and Termination Fees."

Both Macromedia and Adobe have agreed to submit the adoption of the merger agreement, in the case of Macromedia, and the issuance of shares of Adobe common stock in the merger, in the case of Adobe, to their stockholders, regardless of any withdrawal or modification of the respective recommendation by the board of directors of Macromedia or Adobe.

Limitation on the Solicitation, Negotiation and Discussion by Macromedia of Other Acquisition Proposals

The merger agreement contains detailed provisions prohibiting Macromedia from seeking or entering into an alternative transaction to the merger. Under these "no solicitation" and related provisions, subject to specific exceptions described below, Macromedia has agreed that, prior to the earlier of consummation of the merger or the termination of the merger agreement, it will not, directly or indirectly (and that it will (i) ensure that its subsidiaries do not and (ii) use its commercially reasonable efforts to ensure that its directors, officers, other employees, agents, attorneys, accountants, advisors and representatives do not, directly or indirectly):

•: solicit, initiate, knowingly encourage, induce or facilitate the making, submission or announcement of any acquisition proposal or acquisition inquiry;
•: furnish any nonpublic information regarding Macromedia or any of its subsidiaries to any person in connection with or in response to an acquisition proposal or acquisition inquiry;
•: engage in discussions or negotiations with any person with respect to any acquisition proposal or acquisition inquiry;
•: approve, endorse or recommend any acquisition proposal or acquisition inquiry; or
•: enter into any letter of intent or contract relating to any acquisition transaction.

Under the merger agreement, an "acquisition inquiry" is an inquiry, indication of interest or request for nonpublic information (other than those made or submitted by Adobe) that would reasonably be expected to lead to an acquisition proposal, and an "acquisition proposal" is any offer, inquiry or proposal with respect to Macromedia (other than those made or submitted by Adobe) relating to any acquisition transaction.

Under the merger agreement, subject to limited exceptions, an "acquisition transaction" is any transaction or series of related transactions (other than the one contemplated by the merger agreement or as previously disclosed to Adobe pursuant to the merger agreement) involving:

•: any merger, exchange, consolidation, business combination, issuance of securities, acquisition of securities, reorganization, recapitalization, takeover offer, tender offer, exchange offer or similar transaction involving Macromedia or one of its material subsidiaries, in which a third party or group acquires more than a 15% interest in the total outstanding voting securities of Macromedia or one of its material subsidiaries, or in which Macromedia or one of its material subsidiaries issues more than 15% of the outstanding voting securities of Macromedia or that material subsidiary;
•: any sale, lease, exchange, transfer, license, acquisition or disposition of assets representing 15% or more of the consolidated net revenues, consolidated net income or consolidated assets of Macromedia and its subsidiaries; or
•: any liquidation or dissolution of Macromedia or one of its material subsidiaries.

Under the merger agreement, a "material subsidiary" of Macromedia is any subsidiary that accounts for 15% or more of the consolidated net revenues, consolidated net income or consolidated assets of Macromedia and its subsidiaries.

Under the merger agreement, Macromedia agreed to cease any existing discussions with any third party that relate to any acquisition proposal or acquisition inquiry.

Macromedia has agreed to notify Adobe, within 48 hours after receipt of any acquisition proposal or acquisition inquiry, of the identity of the person making the acquisition proposal or acquisition inquiry and the terms thereof. The merger agreement provides that Macromedia must keep Adobe informed of the status of the acquisition proposal or acquisition inquiry and the status and terms of any modifications or proposed modifications thereto.

Macromedia has also agreed not to release or waive any provision of any confidentiality, non-solicitation, no-hire, standstill or similar contract under which Macromedia or any of its subsidiaries has any rights and to use commercially reasonable efforts to enforce such contracts at the request of Adobe.

Exception to the Limitation on the Negotiation and Discussion by Macromedia of Other Acquisition Proposals

The merger agreement provides that, if, prior to the Macromedia special meeting, Macromedia receives from any person an acquisition proposal that constitutes, or could reasonably be expected to result in the submission by such person of, a superior offer (as described below), then Macromedia may furnish nonpublic information to, and engage in discussions and negotiations with, the person making the acquisition proposal, as long as:

•: neither Macromedia nor any of its representatives has breached any of the obligations described under the heading "Limitation on the Solicitation, Negotiation and Discussion by Macromedia of Other Acquisition Proposals" above;
•: Macromedia's board of directors concludes in good faith, after taking into account the advice of its outside legal counsel, that such action is required in order for Macromedia's board of directors to comply with its fiduciary obligations to Macromedia's stockholders under applicable law;
•: Macromedia has given Adobe at least two business days' prior notice of its intention to take such action and the identity of the person who made the acquisition proposal;
•: Macromedia receives an executed confidentiality agreement from the person who made the acquisition proposal with terms at least as favorable to Macromedia as the confidentiality agreement between Macromedia and Adobe; and
•: Macromedia provides Adobe with any nonpublic information to be furnished to the person who made the acquisition proposal (that has not previously been delivered to Adobe) at least two business days prior to furnishing such person with such nonpublic information.

For purposes of the merger agreement, the term "superior offer" means an unsolicited bona fide written offer by an unaffiliated third party to acquire all or substantially all of the assets of Macromedia and its subsidiaries, or more than 50% of the outstanding voting securities of Macromedia and as a result of which the stockholders of Macromedia immediately preceding such transaction would cease to hold at least 50% of the equity interests in the surviving or resulting company or any direct or indirect parent thereof, in exchange for consideration consisting exclusively of cash or publicly traded equity securities or a combination thereof, so long as:

•: the offer was not obtained or made as a direct or indirect result of a breach of any of the obligations described under the heading "Limitation on the Solicitation, Negotiation and Discussion by Macromedia of Other Acquisition Proposals" above;
•: the offer is not subject to a financing contingency; and

•: Macromedia's board of directors, in its good faith judgment, after obtaining and taking into account the advice of an independent financial advisor of nationally recognized reputation and after taking into account the likelihood and anticipated timing of the consummation of the transaction contemplated by such offer, determines that the offer is more favorable from a financial point of view to Macromedia's stockholders than the merger.

Material Adverse Effect

Several of the representations, warranties, covenants, closing conditions and termination provisions of Adobe and Macromedia in the merger agreement use the phrase "material adverse effect." The merger agreement provides that "material adverse effect" means, with respect to either Adobe or Macromedia, as the case may be, any effect, change, event or circumstance that, considered together with other effects, changes, events and circumstances, has a material adverse effect on:

•: the business, financial condition, operations or results of operations of the subject company and its subsidiaries taken as a whole;
•: the ability of the subject company to consummate the merger or to perform any of its covenants or obligations under the merger agreement; or
•: with respect to a "material adverse effect" on Macromedia only, Adobe's ability to vote, transfer, receive dividends with respect to or otherwise exercise ownership rights with respect to the stock of Macromedia as the surviving corporation in the merger.

The merger agreement provides, however, that none of the following will be deemed to constitute, or be taken into account in determining whether there has occurred, a material adverse effect on the particular subject company:

•: effects, changes, events and circumstances resulting from conditions generally affecting the industries in which the subject company and its subsidiaries participate or the U.S. or global economy or capital markets as a whole, to the extent that such conditions do not have a disproportionate impact on the subject company and its subsidiaries taken as a whole;
•: changes in the trading price or trading volume of the subject company's common stock in and of themselves;
•: the loss of (or failure to generate) revenues resulting directly from any delay or cancellation of product orders arising directly from the announcement or pendency of the merger;
•: resignations of employees of the subject company resulting directly from the announcement or pendency of the merger;
•: any failure of the subject company or its subsidiaries to meet internal projections or forecasts or third party revenue or earnings predictions for any period ending on or after the date of the merger agreement, in and of itself;
•: in the case of a material adverse effect on Macromedia only, effects resulting from any stockholder litigation alleging a breach of the fiduciary duties of Macromedia's board of directors relating to the merger in which, based on the underlying merits of such litigation, the prospects for an award of damages or injunctive relief against Macromedia and its directors are very unlikely;
•: effects, changes, events and circumstances resulting from actions taken by the subject company to comply with its obligations under the merger agreement to use commercially reasonable efforts to consummate the merger or to use reasonable best efforts to contest certain antitrust-related challenges to the merger;

•: effects, changes, events and circumstances resulting from the payment of the legal, investment banking and other professional advisory fees and out-of-pocket expenses incurred in connection with the merger and, in the case of a material adverse effect on Macromedia only, the expenditures contemplated by the Macromedia retention and severance plan; and
•: effects, changes, events and circumstances resulting from the adoption or implementation of any required stock option expensing.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

On April 17, 2005, Adobe entered into an agreement to merge with Macromedia in a transaction to be accounted for using the purchase method of accounting for business combinations. Under the terms of the merger agreement, each issued and outstanding common share of Macromedia will be exchanged for 1.38 shares of Adobe common stock. Additionally, the merger agreement provides that, subject to certain exceptions, at the effective time of the merger, each Macromedia stock option that is outstanding and unexercised immediately prior to the effective time will be converted into an option to purchase Adobe common stock and Adobe will assume that stock option (or will replace that stock option by issuing a materially equivalent replacement stock option to purchase Adobe common stock) in accordance with the terms of the applicable Macromedia stock option plan and terms of the stock option agreement relating to that Macromedia stock option.

The following unaudited pro forma condensed combined balance sheet is based on historical balance sheets of Adobe and Macromedia and has been prepared to reflect the merger as if it had been consummated on June 3, 2005. Such pro forma information is based upon the historical consolidated balance sheet data of Adobe at June 3, 2005 and Macromedia at March 31, 2005. The following unaudited pro forma condensed combined statement of income for the fiscal year ended December 3, 2004 combines Adobe's historical consolidated statement of income for the year then ended with Macromedia's historical consolidated statements of income for the nine months ended December 31, 2004 and the three months ended March 31, 2004. The following unaudited pro forma condensed combined statement of income for the six months ended June 3, 2005 combines Adobe's historical consolidated statement of income for the six months then ended with Macromedia's historical consolidated statement of income for the six months ended March 31, 2005.

The unaudited pro forma condensed combined financial statements are based on the estimates and assumptions set forth in the notes to such statements, which are preliminary and have been made solely for purposes of developing such pro forma information. The unaudited pro forma condensed combined financial statements are not necessarily an indication of the results that would have been achieved had the merger been consummated as of the dates indicated or that may be achieved in the future.

Adobe estimates that it will incur direct transaction costs of approximately $26.0 million, which is included as part of the purchase price of the acquisition. This amount is a preliminary estimate and is therefore subject to change. There can be no assurance that Adobe will not incur additional costs in subsequent quarters associated with the proposed merger.

These unaudited pro forma condensed combined financial statements should be read in conjunction with the historical consolidated financial statements and notes thereto of Adobe and Macromedia and other financial information pertaining to Adobe and Macromedia including "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Risk Factors" incorporated by reference or included herein.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Basis of Presentation

On April 17, 2005, Adobe and Macromedia entered into a definitive agreement under which Macromedia will become a wholly owned subsidiary of Adobe in a transaction to be accounted for using the purchase method. The total estimated purchase price of approximately $3.4 billion includes common stock valued at $3.1 billion, stock options assumed and restricted stock exchanged with a fair value of $311.6 million, and estimated direct transaction costs of $26.0 million.

The unaudited pro forma condensed combined financial statements assume the issuance of approximately 103.8 million shares of Adobe common stock based on an exchange ratio of 1.38 shares of Adobe common stock for each outstanding share of Macromedia common stock as of June 3, 2005. The actual number of shares of Adobe common stock to be issued will be determined based on the actual number of shares of Macromedia common stock outstanding upon the consummation of the merger. The average market price per share of Macromedia common stock of $29.43 is based on an average of the closing prices for a range of trading days (April 14, 2005 through April 20, 2005) around the announcement date (April 18, 2005) of the proposed transaction.

Under the terms of the merger agreement, subject to certain exceptions, at the effective time of the merger, each Macromedia stock option that is outstanding and unexercised immediately prior to the effective time will be converted into an option to purchase Adobe common stock and Adobe will assume that stock option (or will replace that stock option by issuing a materially equivalent replacement stock option to purchase Adobe common stock) in accordance with the terms of the applicable Macromedia stock option plan and terms of the stock option agreement relating to that Macromedia stock option. Based on Macromedia's stock options outstanding at June 3, 2005, Adobe would convert options to purchase approximately 13.0 million shares of Macromedia common stock into options to purchase approximately 17.9 million shares of Adobe common stock. The actual number of Adobe stock options into which Macromedia stock options will be converted will be determined based on the actual number of Macromedia stock options outstanding at the consummation of the merger. The fair value of the outstanding options was determined using a Black-Scholes valuation model with the following weighted-average assumptions: volatility of 32%; risk-free interest rates ranging from 2.98%-3.98%, expected lives ranging from 1-3 years and dividend yield of zero. In addition, Adobe will exchange Adobe's restricted stock for all of Macromedia's outstanding restricted stock, after applying the exchange ratio. Based on the total number of shares of Macromedia restricted stock outstanding at June 3, 2005, Adobe would exchange approximately 0.4 million shares of restricted stock for the outstanding Macromedia restricted stock. The actual number of shares of restricted stock to be exchanged will be determined based on the actual number of shares of Macromedia restricted stock outstanding upon the consummation of the merger. The fair value of the outstanding shares of restricted stock was determined based on their intrinsic value at the announcement date.

The estimated purchase price and the allocation of the estimated purchase price discussed below are preliminary because the proposed merger has not yet been consummated. The actual purchase price will be based on the Adobe shares issued to Macromedia stockholders, the options to purchase Macromedia stock assumed by Adobe and the restricted stock exchanged on the closing date of the merger. The final allocation of the purchase price will be based on Macromedia's assets and liabilities on the date the merger is consummated.

120

The preliminary estimated total purchase price of the merger is as follows (in thousands):

Value of Adobe stock issued	$	3,053,855
Estimated fair value of options assumed and restricted stock exchanged		311,560
Direct transaction costs		26,000

Total preliminary estimated purchase price	$	3,391,415

Under the purchase method of accounting, the total estimated purchase price as shown in the table above is allocated to Macromedia's net tangible and intangible assets based on their estimated fair values as of the date of the completion of the merger. The management of Adobe and Macromedia have allocated the preliminary estimated purchase price based on preliminary estimates that are described in the introduction to these unaudited pro forma condensed combined financial statements. The allocation of the preliminary purchase price and the estimated useful lives and first year amortization associated with certain assets is as follows (in thousands):

		Amount		First Year Amortization		Estimated Useful Life
Net tangible assets		$	487,821		—	N/A
Identifiable intangible assets:
	Acquired product rights		372,700	$	84,060	3-4 years
	Customer contracts and relationships		190,000		25,484	1-8 years
	Non-competition agreements		400		129	2 years
	Trademarks		130,100		19,300	5 years
Goodwill			2,101,069		—	N/A
Deferred stock-based compensation			109,325		44,592	2.5 years	(1)

Total preliminary estimated purchase price		$	3,391,415	$	173,565

(1): Estimated weighted-average remaining vesting period.

A preliminary estimate of $487.8 million has been allocated to net tangible assets acquired and approximately $693.2 million has been allocated to amortizable intangible assets acquired. The amortization related to the amortizable intangible assets is reflected as pro forma adjustments to the unaudited pro forma condensed combined statements of operations.

Identifiable intangible assets. Acquired product rights include developed and core technology and patents. Developed technology relates to Macromedia products across all of their product lines that have reached technological feasibility. Core technology and patents represent a combination of Macromedia's processes, patents and trade secrets developed through years of experience in design and development of their products. Adobe expects to amortize the fair value of the acquired product rights based on the pattern in which the economic benefits of the intangible asset will be consumed.

Customer contracts and relationships represent existing contracts that relate primarily to underlying customer relationships. Adobe expects to amortize the fair value of these assets based on the pattern in which the economic benefits of the intangible asset will be consumed.

Trademarks primarily relate to the Flash trade name and other product names, which Adobe expects to amortize based on the pattern in which the economic benefits of the intangible asset will be consumed.

The method of future amortization will be based on the pattern in which the economic benefits of the intangible assets are consumed. This results in total estimated amortization expense for fiscal years

121

2005, 2006, 2007, 2008 and 2009 of $129.0 million, $209.6 million, $202.1 million, $75.0 million and $77.5 million, respectively.

In-process research and development. As of the filing date, no amounts have been allocated to in-process research and development. This determination was based on the assumption that some research and development projects which are currently in process may not be in process upon consummation of the merger. In-process research and development will be dependent on the status of new projects on the date the merger is consummated. Accordingly, actual results may vary from projected results.

Goodwill. Approximately $2.1 billion has been allocated to goodwill. Goodwill represents the excess of the purchase price over the fair value of the underlying net tangible and intangible assets. In accordance with SFAS No. 142, Goodwill and Other Intangible Assets, goodwill will not be amortized but instead will be tested for impairment at least annually (more frequently if certain indicators are present). In the event that the management of the combined company determines that the value of goodwill has become impaired, the combined company will incur an accounting charge for the amount of impairment during the fiscal quarter in which the determination is made.

Deferred tax liability. Approximately $171.0 million was established as a deferred tax liability for the future amortization of the intangible assets. In accordance with Statement of Financial Accounting Standards No. 109, Accounting For Income Taxes, the valuation allowance on Macromedia's financial statements as of March 31, 2005 was reduced by $171.0 million to the extent the deferred tax assets are more likely than not realizable.

2. Reclassifications

Certain reclassification adjustments have been made to conform Adobe's and Macromedia's historical reported balances to the pro forma combined condensed financial statement basis of presentation. The reclassifications are as follows:

(A): To reclassify Macromedia's credit to its provision for doubtful accounts from sales and marketing to general and administrative expenses to conform to Adobe's presentation.
(B): To reclassify Macromedia's services and support revenue to a separate line item to conform to Adobe's presentation.
(C): To reclassify Macromedia's services and support cost of revenue expenses to a separate line item to conform to Adobe's presentation.

3. Pro Forma Adjustments

Pro forma adjustments are necessary to reflect the estimated purchase price, to reflect amounts related to Macromedia's net tangible and intangible assets at an amount equal to the preliminary estimate of their fair values, to reflect the amortization expense related to the estimated amortizable intangible assets and deferred stock-based compensation, to reflect changes in depreciation and amortization expense resulting from the estimated fair value adjustments to net tangible assets and to reflect the income tax effect related to the pro forma adjustments.

There were no significant intercompany balances and transactions between Adobe and Macromedia as of the dates and for the periods of these pro forma condensed combined financial statements.

The pro forma combined provision for income taxes does not necessarily reflect the amounts that would have resulted had Adobe and Macromedia filed consolidated income tax returns during the periods presented.

The unaudited pro forma condensed combined financial statements do not include any adjustments for liabilities that may result from integration activities, as management of Adobe and Macromedia are in the process of making these assessments, and estimates of these costs are not currently known. However, liabilities ultimately may be recorded for severance or relocation costs related to Macromedia employees, costs of vacating some facilities (leased or owned) of Macromedia, or other costs associated with exiting activities of Macromedia that would affect amounts in the unaudited pro forma condensed combined financial statements. Any such liabilities would be recorded as an adjustment to the purchase price and an increase in goodwill. In addition, Adobe may incur significant restructuring charges upon consummation of the merger or in subsequent quarters for severance or relocation costs related to Adobe employees, costs of vacating some facilities (leased or owned) of Adobe, and other costs associated with exiting activities of Adobe. Any such restructuring charges would be recorded as an expense in the consolidated statement of income in the period in which they were incurred.

Adobe has not identified any pre-merger contingencies where the related asset, liability or impairment is probable and the amount of the asset, liability or impairment can be reasonably estimated. Prior to the end of the purchase price allocation period, if information becomes available which would indicate it is probable that such events have occurred and the amounts can be reasonably estimated, such items will be included in the purchase price allocation.

The pro forma adjustments included in the unaudited pro forma condensed combined financial statements are as follows:

(a): To eliminate Macromedia's historical intangible assets
(b): To eliminate Macromedia's historical goodwill
(c): To eliminate Macromedia's equity
(d): To record the fair value of Adobe shares exchanged in the transaction
(e): To record the fair value of Macromedia stock options assumed and of restricted stock exchanged
(f): To record deferred stock-based compensation related to unvested Macromedia stock options assumed
(g): To accrue Adobe's direct costs of the transaction
(h): To record the fair value of Macromedia's identifiable intangible assets
(i): To adjust Macromedia land and buildings to fair value
(j): To adjust deferred revenue to the fair value of the legal performance obligations under Macromedia existing contracts
(k): To record Macromedia lease obligations in excess of fair value
(l): To record the fair value of receivables from customer contracts that contain minimum guaranteed revenue amounts with extended payment terms
(m): To record the fair value of Macromedia investments
(n): To record goodwill
(o): To record the deferred tax assets and liability related to the identifiable intangible assets
(p): To net deferred tax assets and liabilities for financial statement presentation
(q): To eliminate Macromedia's historical amortization of developed technology, purchased technology and product localization costs

123

(r): To eliminate Macromedia's historical amortization of deferred stock-based compensation
(s): To eliminate Macromedia's historical amortization of other intangible assets
(t): To amortize acquired product rights based upon the pattern in which the economic benefits of the intangible assets will be consumed
(u): To amortize other intangible assets based upon the pattern in which the economic benefits of the intangible asset will be consumed
(v): To amortize deferred stock-based compensation
(w): To amortize lease obligations in excess of fair value
(x): To adjust tax provision to reflect the effect of the pro forma adjustments

4. Pro Forma Net Income Per Share

The pro forma basic and diluted net income per share are based on the number of Adobe shares used in computing basic and diluted net income per share plus the number of Macromedia shares used in computing basic and diluted net income per share multiplied by the exchange ratio. All Adobe historical and pro forma per-share amounts reflect the retroactive effects of all Adobe stock splits including the two-for-one stock split in the form of a stock dividend effective May 23, 2005.

DESCRIPTION OF ADOBE COMMON STOCK AND
PREFERRED STOCK PURCHASE RIGHTS

Adobe Common Stock

The following describes certain provisions of the certificate of incorporation and bylaws of Adobe. Adobe's restated certificate of incorporation, as corrected by the certificate of correction of restated certificate of incorporation, and amended and restated bylaws are included as exhibits to the registration statement of which this joint proxy statement/prospectus is a part. Adobe's certificate of incorporation authorizes the issuance of 902,000,000 shares, consisting of two classes: 900,000,000 shares of common stock, $0.0001 par value per share, and 2,000,000 shares of preferred stock, $0.0001 par value per share.

As of July 19, 2005, there were 492,276,674 shares of Adobe common stock outstanding held of record by 1,668 stockholders.

Voting Rights. Each holder of shares of Adobe common stock is entitled to one vote for each share held on all matters submitted to a vote of Adobe stockholders. Adobe's certificate of incorporation does not provide for cumulative voting, and as a result, the holders of a majority of the shares of Adobe common stock voted can elect all of the directors then standing for election.

Dividend Rights. Adobe's bylaws provide that, subject to the provisions of Adobe's certificate of incorporation, the Adobe board of directors may declare dividends pursuant to law at any regular or special meeting. Dividends may be paid in cash, in property or in shares of capital stock, subject to the provisions of the certificate of incorporation. Before payment of any dividend, the board may set aside any funds of the corporation available for dividends as the board from time to time, in its absolute discretion, thinks proper as a reserve for any purpose the board thinks conducive to the interests of Adobe.

No Preemptive or Similar Rights. The Adobe common stock is not entitled to preemptive rights and is not subject to conversion or redemption.

Right to Receive Liquidation Distributions. Upon a liquidation, dissolution or winding-up of Adobe, holders of Adobe common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding preferred stock.

Anti-Takeover Provisions. The provisions of the Delaware General Corporation Law and Adobe's certificate of incorporation and bylaws may have the effect of delaying, deferring or discouraging another person's acquiring control of Adobe.

A corporation can elect not to be governed by Section 203 of the Delaware General Corporation Law, which generally protects publicly traded Delaware corporations from hostile takeovers and from certain actions following such takeovers. Adobe has not made this election and is therefore governed by Section 203 of the Delaware General Corporation Law, which as a result, may discourage attempts to acquire Adobe.

In addition, provisions of Adobe's certificate of incorporation and rights agreement, as amended, described below under the captions "Comparative Rights of Adobe Stockholders and Macromedia Stockholders—Classification of Board of Directors" and "—Stockholder Rights Plan," respectively, may also have the effect of delaying, deferring or discouraging another person's acquiring control of Adobe.

Transfer Agent. The transfer agent for Adobe common stock is Computershare Investor Services, LLC.

125

Listing. Adobe common stock is quoted on the NASDAQ National Market under the symbol "ADBE."

Adobe Preferred Stock Purchase Rights

The following describes certain provisions of the rights agreement, as amended, of Adobe. The rights agreement and the amendment thereto are included as exhibits to the registration statement of which this joint proxy statement/prospectus is a part. In 2000, Adobe adopted the Fourth Amended and Restated Rights Agreement with Computershare Investors Services, LLC as rights agent. In 2003, Adobe and Computershare Investors Services, LLC agreed to Amendment No. 1 to the rights agreement. In connection with the initial adoption of the rights agreement, Adobe's board of directors declared a dividend of one preferred stock purchase right for each share of Adobe common stock outstanding on July 24, 1990 and authorized the further issuance of one preferred stock purchase right with respect to each share of Adobe common stock that was subsequently issued between that date and the distribution date described below. Each right entitles the holder, under certain circumstances, to purchase from Adobe one-thousandth of a share of Adobe's Series A preferred stock at a price of $700 per one thousandth of a share of Series A preferred stock, subject to adjustment. The rights, preferences and privileges of Adobe's Series A preferred stock are described in the certificate of designation of Series A preferred stock included as an exhibit to the registration statement of which this joint proxy statement/prospectus is a part.

Initially, the rights are attached to outstanding certificates representing Adobe common stock, and no separate certificates representing the rights are distributed. The rights will be represented by separate certificates and will become exercisable upon the earlier of:

•: the close of business on the tenth day following a public announcement by Adobe or any person or group that any person or group has acquired, subject to certain exceptions, without the approval of the Adobe board of directors, beneficial ownership of 15% or more of Adobe's outstanding common stock (or such earlier date that the board becomes aware that any such person or group has acquired, without the approval of the board, beneficial ownership of 15% or more of Adobe's outstanding common stock); or
•: the tenth business day following the commencement by any person or group of a tender offer which would result in such person or group, subject to certain exceptions, owning 15% or more of Adobe's outstanding common stock.

Under the rights agreement, as amended, the "distribution date" means the earlier of the two dates described above. The proposed merger involving Adobe and Macromedia will not cause the rights to become exercisable.

"Flip-In" Feature. In the event any person or group, subject to certain exceptions, becomes the beneficial owner of more than 15% of the outstanding common stock of Adobe, then each holder of a right (other than such person or group acquiring such beneficial ownership) will have the right to receive, upon exercise and payment of the exercise price, that number of shares of Adobe common stock having a market value of two times the exercise price of the right. If Adobe does not have enough authorized but unissued shares of common stock to satisfy this obligation, then Adobe will deliver an amount in cash equivalent in value to the common stock issuable upon exercise of a right.

"Flip-Over" Feature. In the event that at any time after the distribution date Adobe is acquired in a merger or other business combination, then each holder of a right will have the right to purchase the number of shares of validly issued, fully paid and nonassessable and freely tradable common stock of the acquiring company equal to the result obtained by dividing the exercise price of the right by 50% of the current market price of the common stock of such acquiring company.

126

"Exchange" Feature. At any time after any person or group has acquired, subject to certain exceptions, without the approval of the Adobe board of directors, beneficial ownership of 15% or more of Adobe's outstanding common stock and prior to the time such person or group becomes the beneficial owner of 50% or more of the shares of Adobe common stock, the board may exchange all or part of the then outstanding and exercisable rights for units of Series A preferred stock at an exchange ratio of one unit of Series A preferred stock per right. Each unit of Series A preferred stock is equal to one-thousandth of a share of Series A preferred stock.

Redemption of Rights. The Adobe board of directors may, at any time prior to the tenth day following the first public announcement that a person or group, subject to certain exceptions, has acquired beneficial ownership of more than 15% of Adobe's outstanding common stock or July 23, 2010, redeem all but not less than all the then outstanding rights at a redemption price of $0.01 per right.

Amendment of Rights. The terms of the rights agreement, as amended, may be amended from time to time:

•: to cure any ambiguity;
•: to correct or supplement any provision which may be defective;
•: prior to the close of business on the tenth day following a public announcement that any person or group has acquired, subject to certain exceptions, without the approval of the Adobe board of directors, beneficial ownership of 15% or more of Adobe's outstanding common stock (or such earlier date that the board becomes aware that any such person or group has acquired, without the approval of the board, beneficial ownership of 15% or more of Adobe's outstanding common stock); or
•: after the rights are no longer redeemable, to amend the terms as Adobe may deem necessary, but not in any way that will adversely affect the interests of rights holders, provided however, that the rights may not be amended in order to lengthen the period of time when the rights may be redeemed.

Final Expiration Date. The rights will expire at the close of business on July 23, 2010 unless earlier redeemed or exchanged by Adobe.

Anti-takeover Effects. The rights agreement, as amended, approved by the Adobe board of directors is designed to protect and maximize the value of Adobe's outstanding equity interests in the event of an unsolicited attempt to acquire Adobe in a manner or on terms not approved by the board of directors and that prevent Adobe's stockholders from realizing the full value of their shares of Adobe common stock. However, the rights may have the effect of rendering more difficult or discouraging an acquisition of Adobe that is deemed undesirable by Adobe's board of directors. The rights may cause substantial dilution to a person or group that attempts to acquire Adobe on terms or in a manner not approved by Adobe's board of directors, except pursuant to an offer conditioned upon the negation, purchase or redemption of the rights.

This summary of the rights does not purport to be complete and is qualified in its entirety by reference to the full text of the rights agreement, as amended, which is incorporated herein by reference. You should read the rights agreement, as amended, carefully. For information on how to get a copy of the rights agreement, as amended, see "Where You Can Find More Information" below.

COMPARATIVE RIGHTS OF ADOBE STOCKHOLDERS
AND MACROMEDIA STOCKHOLDERS

Both Adobe and Macromedia are incorporated under the laws of the State of Delaware and, accordingly, the rights of the stockholders of each are currently, and will continue to be, governed by the Delaware General Corporation Law. Before the consummation of the merger, the rights of holders of Macromedia common stock are also governed by the amended and restated certificate of incorporation of Macromedia, the amended and restated bylaws of Macromedia and the Rights Agreement between Macromedia and Mellon Investor Services LLC, as amended. After the consummation of the merger, Macromedia stockholders will become stockholders of Adobe, and their rights will be governed by the Delaware General Corporation Law, the restated certificate of incorporation of Adobe, as corrected by the certificate of correction of restated certificate of incorporation, the amended and restated bylaws of Adobe and the Fourth Amended and Restated Rights Agreement between Adobe and Computershare Investor Services, LLC, as amended.

Macromedia shall pay all expenses (including attorneys' fees) incurred by a director or officer in defending any proceeding as they are incurred in advance of its final disposition; provided, however, that if the Delaware General Corporation Law then so requires, the payment of expenses incurred by a director or officer in advance of the final disposition of a proceeding shall be made only after receiving an undertaking by the director or officer to repay all amounts advanced if it should be determined ultimately that the director or officer is not entitled to be indemnified under this provisions of the bylaws or otherwise.	was a director or executive officer of the corporation, or was serving at the request of the corporation as a director or executive officer of another corporation, partnership, joint venture, trust or other enterprise, prior to the final disposition of the proceeding, all expenses incurred by any director or executive officer in connection with such proceeding if such person provides an undertaking to repay all amounts if it is ultimately determined that the person is not entitled to be indemnified under the bylaw or otherwise.

"Flip-In" Feature. In the event any person or group, subject to certain exceptions, becomes the beneficial owner of more than 20% of the outstanding common stock of Macromedia, then each holder of a right (other than such person or group acquiring such beneficial ownership) will have the right to receive upon exercise and payment of the exercise price that number of shares of Macromedia common stock having a market value of two times the exercise price of the right. If Macromedia does not have enough authorized but unissued shares of common stock to satisfy this obligation, then Macromedia will deliver an amount in cash equivalent in value to the common stock issuable upon exercise of a right. "Flip-Over" Feature. In the event that at any time after the distribution date Macromedia is acquired in a merger or another business combination then each holder of a right (other than such acquiring person or group) shall have the right to purchase the number of shares of common stock of the acquiring company that at the time of the transaction will have a market value of two times the exercise price of the right.

Under the rights agreement, as amended, the "distribution date" means the earlier of the two dates described above. "Flip-In" Feature. In the event any person or group, subject to certain exceptions, becomes the beneficial owner of more than 15% of the outstanding common stock of Adobe, then each holder of a right (other than such person or group acquiring such beneficial ownership) will have the right to receive, upon exercise and payment of the exercise price, that number of shares of Adobe common stock having a market value of two times the exercise price of the right. If Adobe does not have enough authorized but unissued shares of common stock to satisfy this obligation, then Adobe will deliver an amount in cash equivalent in value to the common stock issuable upon exercise of a right. "Flip-Over" Feature. In the event that at any time after the distribution date Adobe is acquired in a merger or another business combination, then

135

		"Exchange" Feature. At any time after a person or group, subject to certain exceptions, has become the beneficial owner of more than 20% of the outstanding common stock of Macromedia but before that person has acquired a majority of the outstanding common stock, the board may exchange all or some of the rights at an exchange ratio of one common share per right. Redemption of Rights. At any time before a person or group, subject to certain exceptions, has become the beneficial owner of more than 20% of the outstanding common stock of Macromedia, the board may redeem all, but not some, of the rights at a price of $0.001 per right on terms and conditions established by the board. After the period for redemption of rights has expired, the board may not amend the rights agreement to extend the period for redemption of the rights. Immediately upon any redemption of the rights, the right to exercise the rights will terminate and the only right of the holders of rights will be to receive the redemption price. Amendment of Rights. The terms of the rights may be amended by a resolution of the board without the consent of the holders of the rights, except that after a person or group, subject to certain exceptions becomes the beneficial owner of more than 20% of the outstanding common stock of Macromedia, no amendment may adversely affect the interests of the holders of the rights. Final Expiration Date. The rights will expire at the close of business on October 28, 2011 unless the expiration date is extended or the rights are earlier redeemed or exchanged by Macromedia. Anti-takeover Effects. The Macromedia rights agreement is designed to cause significant dilution		each holder of a right shall have the right to purchase the number of shares of validly issued, fully paid and nonassessable and freely tradable common stock of the acquiring company equal to the result obtained by dividing the exercise price of the right by 50% of the current market price of such common stock of the acquiring company. "Exchange" Feature. At any time after any person or group has acquired, subject to certain exceptions, without the approval of the board, beneficial ownership of 15% or more of Adobe's outstanding common stock and prior to the time such person or group becomes the beneficial owner of 50% or more of the shares of Adobe common stock, the board may exchange all or part of the then outstanding and exercisable rights for units of Series A preferred stock at an exchange ratio of one unit of Series A preferred stock per right. Each unit of Series A preferred stock is equal to one-thousandth of a share of Series A preferred stock. Redemption of Rights. The board may, at any time prior to the tenth day following the first public announcement that a person or group, subject to certain exceptions, has acquired beneficial ownership of more than 15% of Adobe's outstanding common stock or July 23, 2010, redeem all but not less than all the then outstanding rights at a redemption price of $0.01 per right. Amendment of Rights. The terms of the rights agreement may be amended from time to time: (i) to cure any ambiguity; (ii) to correct or supplement any provision which may be defective; (iii) prior to the close of business on the tenth day following a public announcement that any person or group has acquired, subject to

136

	to a person or group that attempts to acquire or merge with Macromedia in a manner or on terms that are not approved by Macromedia's board. The Macromedia rights agreement was amended in connection with the execution of the merger agreement to exclude Adobe, Merger Sub or any their affiliates from the definition of "Acquiring Person." Accordingly, none of the provisions of the rights agreement will be triggered by the proposed merger with Adobe described in this joint proxy statement/prospectus.	certain exceptions, without the approval of the board, beneficial ownership of 15% or more of Adobe's outstanding common stock (or such earlier date that the board becomes aware that any such person or group has acquired, without the approval of the board, beneficial ownership of 15% or more of Adobe's outstanding common stock); or (iv) after the rights are no longer redeemable, to amend the provisions as Adobe may deem necessary, but not in any way that will adversely affect the interests of rights holders, provided however, that the rights may not be amended in order to lengthen the period of time when the rights may be redeemed. Final Expiration Date. The rights will expire at the close of business on July 23, 2010 unless earlier redeemed or exchanged by Adobe. Anti-takeover Effects. The Adobe rights agreement is designed to cause significant dilution to a person or group that attempts to acquire or merge with Adobe in a manner or on terms that are not approved by Adobe's board.
Dissenters' Rights	Appraisal rights are not available to Macromedia stockholders with respect to the merger.	Appraisal rights are not available to Adobe stockholders with respect to the merger.
Certain Business Combination Restrictions	Section 203 of the Delaware General Corporation Law generally protects publicly traded Delaware corporations from hostile takeovers and from certain actions following such takeovers. The restrictions set forth in Section 203 of the Delaware General Corporation Law, with respect to the merger with Merger Sub, do not apply because Macromedia's board has expressly approved the merger agreement and the stockholder voting agreements.	Under Delaware law a corporation can elect not to be governed by Section 203 of the Delaware General Corporation Law, which generally protects publicly traded Delaware corporations from hostile takeovers and from certain actions following such takeovers. Adobe has not made this election and is therefore governed by Section 203 of the Delaware General Corporation Law.
Vote on Business Combinations	Neither the Macromedia certificate of incorporation nor its bylaws contain any provisions relating to business combinations.	Neither the Adobe certificate of incorporation nor its bylaws contain any provisions relating to business combinations.

LEGAL MATTERS

The validity of the Adobe common stock to be issued in the merger has been passed upon for Adobe by Cooley Godward LLP. Certain tax consequences of the merger have been passed upon for Adobe by Cooley Godward LLP and for Macromedia by Fenwick & West LLP.

EXPERTS

The consolidated financial statements of Adobe as of December 3, 2004 and November 28, 2003, and for each of the years in the three-year period ended December 3, 2004, and related financial statement schedule, and management's assessment of the effectiveness of internal control over financial reporting as of December 3, 2004, incorporated in this joint proxy statement/prospectus by reference to the Annual Report on Form 10-K for the year ended December 3, 2004, have been so incorporated in reliance on the reports of KPMG LLP, independent registered public accounting firm, given on the authority of that firm as experts in auditing and accounting. The audit report covering the December 3, 2004 and November 28, 2003 consolidated financial statements refers to changes in the method of accounting for goodwill in 2003, as discussed in Note 1 to the consolidated financial statements.

The consolidated financial statements and schedule of Macromedia and its subsidiaries as of March 31, 2005 and 2004, and for each of the years in the three-year period ended March 31, 2005, and management's assessment of the effectiveness of internal control over financial reporting as of March 31, 2005, have been incorporated by reference in this joint proxy statement/prospectus in reliance upon the reports of KPMG LLP, independent registered public accounting firm, incorporated by reference herein, and upon the authority of said firm as experts in accounting and auditing.

The audit report dated June 14, 2005, on management's assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of March 31, 2005, expresses an opinion that Macromedia and its subsidiaries did not maintain effective internal control over financial reporting as of March 31, 2005, because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states that the policies and procedures of Macromedia and its subsidiaries did not include adequate management oversight and review of Macromedia and its subsidiaries' accounting for income taxes. This lack of adequate management oversight and review resulted in errors in Macromedia and its subsidiaries' income tax expense and the corresponding deferred tax assets and liabilities. Because of this deficiency, there is more than a remote likelihood that a material misstatement in Macromedia and its subsidiaries' annual or interim consolidated financial statements would not be prevented or detected.

AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

Section 1. DESCRIPTION OF TRANSACTION

1.1 Merger of Merger Sub into the Company. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company. By virtue of the Merger, at the Effective Time, the separate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation in the Merger (the "Surviving Corporation").

1.2 Effects of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the DGCL.

1.3 Closing; Effective Time. The consummation of the Merger (the "Closing") shall take place at the offices of Cooley Godward llp, 3175 Hanover Street, Palo Alto, California, on a date to be designated by Parent, which shall be no later than the second business day after the satisfaction or waiver of the last to be satisfied or waived of the conditions set forth in Sections 6 and 7 (other than the conditions set forth in Sections 6.7 and 7.7, which by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of each of such conditions). The date on which the Closing actually takes place is referred to as the "Closing Date." Subject to the provisions of this Agreement, a certificate of merger that the parties shall agree satisfies the applicable requirements of the DGCL shall be duly executed by the Company and concurrently with or as soon as practicable following the Closing shall be filed with the Secretary of State of the State of Delaware. The Merger shall become effective at the time of the filing of such certificate

A-1

of merger with the Secretary of State of the State of Delaware or at such later time as may be agreed by Parent and the Company and specified in such certificate of merger (the time as of which the Merger becomes effective being referred to as the "Effective Time").

1.4 Certificate of Incorporation and Bylaws; Directors and Officers. Unless otherwise determined by Parent prior to the Effective Time:

(a) the Certificate of Incorporation of the Surviving Corporation shall be amended and restated immediately after the Effective Time to conform to Exhibit B;

(b) the Bylaws of the Surviving Corporation shall be amended and restated as of the Effective Time to conform to the Bylaws of Merger Sub as in effect immediately prior to the Effective Time; and

(c) the directors and officers of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are directors and officers of Merger Sub immediately prior to the Effective Time.

1.5 Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company:

(i) any shares of Company Common Stock held by any wholly-owned Subsidiary of the Company immediately prior to the Effective Time (or held in the Company's treasury) (together with any associated Company Rights, as defined in Section 2.3) shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any shares of Company Common Stock held by Parent, Merger Sub or any other wholly-owned Subsidiary of Parent immediately prior to the Effective Time (together with any associated Company Rights) shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii) except as provided in clauses "(i)" and "(ii)" above and subject to Sections 1.5(b), 1.5(c) and 1.5(d), each share of Company Common Stock outstanding immediately prior to the Effective Time (together with any associated Company Rights) shall be converted into the right to receive 0.69 of a share of Parent Common Stock; and

(iv) each share of the common stock, $.001 par value per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation.

The fraction of a share of Parent Common Stock specified in Section 1.5(a)(iii) (as such fraction may be adjusted in accordance with this Section 1.5(b)) is referred to as the "Exchange Ratio."

(b) If, during the period from the date of this Agreement through the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, or if a stock dividend is declared by the Company or Parent during such period, or a record date with respect to any such event shall occur during such period, then the Exchange Ratio shall be adjusted to the extent appropriate. For the avoidance of doubt, the fraction of a share of Parent Common Stock specified in Section 1.5(a)(iii) does not give effect to the two-for-one stock split in the form of a stock dividend announced by Parent on March 17, 2005 and having a proposed record date of May 2, 2005.

A-2

(c) If any shares of Company Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other Contract with the Company or under which the Company has any rights, then: (i) the shares of Parent Common Stock issued in exchange for such shares of Company Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition; and (ii) the certificates representing such shares of Parent Common Stock may accordingly be marked with appropriate legends. Prior to the Effective Time, the Company shall use commercially reasonable efforts to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other Contract.

(d) No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender of such holder's Company Stock Certificate(s) (as defined in Section 1.6), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing price of a share of Parent Common Stock on the Parent Primary Exchange on the date the Merger becomes effective.

1.6 Closing of the Company's Transfer Books. At the Effective Time: (a) all shares of Company Common Stock outstanding immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist (in exchange for the right to receive the applicable consideration set forth in, and subject to, Sections 1.5 and 1.7), and all holders of certificates representing shares of Company Common Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company; and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Common Stock outstanding immediately prior to the Effective Time (a "Company Stock Certificate") is presented to the Exchange Agent (as defined in Section 1.7) or to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.7.

1.7 Exchange of Certificates.

(a) On or prior to the Closing Date, Parent shall select a reputable bank or trust company reasonably acceptable to the Company to act as exchange agent in the Merger (the "Exchange Agent"). As promptly as practicable after the Effective Time, Parent shall deposit with the Exchange Agent: (i) certificates representing the shares of Parent Common Stock issuable pursuant to Section 1.5; and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 1.5(d). The shares of Parent Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares of Parent Common Stock, are referred to collectively as the "Exchange Fund."

(b) As promptly as practicable after the Effective Time, the Exchange Agent will mail to the Persons who were record holders of Company Stock Certificates immediately prior to the Effective Time: (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify and the Company shall reasonably approve prior to the

A-3

Effective Time (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent); and (ii) instructions for use in effecting the surrender of Company Stock Certificates in exchange for certificates representing Parent Common Stock. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent: (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of Section 1.5 (and cash in lieu of any fractional share of Parent Common Stock); and (B) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.7(b), each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by Section 1.5. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its reasonable discretion and as a condition to the issuance of any certificate representing Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, Parent or the Surviving Corporation with respect to such Company Stock Certificate.

(c) Notwithstanding anything to the contrary contained in this Agreement, no shares of Parent Common Stock (or certificates therefor) shall be issued in exchange for any Company Stock Certificate to any Person who was an "affiliate" (as that term is used in Rule 145 under the Securities Act) of the Company at the time of the Company Stockholders' Meeting (as defined in Section 5.2(a)) until such Person shall have delivered to Parent and the Company a duly executed Affiliate Agreement required by Section 5.9.

(d) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid or otherwise delivered to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate in accordance with this Section 1.7. Subject to applicable Legal Requirements (including applicable abandoned property, escheat or similar laws), following surrender of any such Company Stock Certificate, the Exchange Agent will deliver to the record holder thereof, without interest: (i) a certificate representing the number of whole shares of Parent Common Stock issued in exchange therefor along with cash in lieu of any fractional share pursuant to Section 1.5(d) and the amount of any such dividends or other distributions with a record date after the Effective Time (and with a payment date prior to the date of surrender of such Company Stock Certificate) payable with respect to such whole shares of Parent Common Stock; and (ii) on the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time (and with a payment date on or subsequent to the date of surrender of such Company Stock Certificate) payable with respect to such whole shares of Parent Common Stock.

(e) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date 180 days after the date on which the Merger becomes effective shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.7 shall thereafter look only to Parent for satisfaction of their

A-4

claims for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to shares of Parent Common Stock.

(f) Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Common Stock such amounts as may be required to be deducted or withheld from such consideration under the Code or any provision of state, local or foreign tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(g) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any shares of Parent Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, delivered to any public official pursuant to any applicable abandoned property law, escheat law or other similar Legal Requirement.

The parties to this Agreement adopt this Agreement as a "plan of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

1.9 Further Action. If, at any time after the Effective Time, any further action is determined by Parent or the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

A-20

No Company Employee Plan provides (except at no cost to the Acquired Corporations or any Company Affiliate), or reflects or represents any liability of any of the Acquired Corporations or any Company Affiliate to provide, post-termination or retiree life insurance, post-termination or retiree health benefits or other post-termination or retiree employee welfare benefits to any Person for any reason, except as may be required by COBRA or other applicable Legal Requirements.

(k) Except: (i) as set forth in Part 2.16(k) of the Company Disclosure Schedule; or (ii) as would not have and would not reasonably be expected to have or result in a Company Material Adverse Effect, each of the Acquired Corporations and Company Affiliates: (A) is, and at all times has been, in compliance in all material respects with any Order or arbitration award of any court, arbitrator or any Governmental Body respecting employment, employment practices, terms and conditions of employment, wages, hours or other labor related matters; (B) has withheld and reported all amounts required by applicable Legal Requirements or by Contract to be withheld and reported with respect to wages, salaries and other payments to Company Associates; (C) is not liable for any arrears of wages or any taxes or any interest or penalty for failure to comply with the Legal Requirements applicable of the foregoing; and (D) is not liable for any payment to any trust or other fund governed by or maintained by or on behalf of any Governmental Body with respect to unemployment compensation benefits, social security, social charges or other benefits or obligations for Company Associates (other than routine payments to be made in the normal course of business and consistent with past practice), except as would not and would not reasonably be expected to result in any liability that is material to the Acquired Corporations taken as a whole.

(l) As of the date of this Agreement, there is no agreement, plan, arrangement or other Contract covering any Company Employee, and no payments have been made or will be made to any Company Employee, that, considered individually or considered collectively with any other such Contracts or payments, will, or could reasonably be expected to, be characterized as a "parachute payment" within the meaning of Section 280G(b)(2) of the Code or give rise directly or indirectly to the payment of any amount that would not be deductible pursuant to Section 162(m) of the Code (or any comparable provision under state or foreign Tax laws).

(b) Subject to Section 5.3(c): (i) the Joint Proxy Statement/Prospectus shall include a statement to the effect that the board of directors of Parent recommends that Parent's stockholders vote to approve the issuance of Parent Common Stock in the Merger (the recommendation of Parent's board of directors that Parent's stockholders vote to approve the issuance of Parent Common Stock in the Merger being referred to as the "Parent Board Recommendation"); and (ii) the Parent Board Recommendation shall not be withdrawn or modified in a manner adverse to the Company, and no resolution by the board of directors of Parent or any committee thereof to withdraw the Parent Board Recommendation or modify the Parent Board Recommendation in a manner adverse to the Company shall be adopted. Subject to the Company's rights under Section 8 and the other provisions of this Agreement, nothing in this Section 5.3(b) shall preclude Parent from making any accurate and complete public disclosure of any material facts if: (1) Parent's board of directors determines in good faith, after taking into account the advice of Parent's outside legal counsel, that such disclosure is required by the fiduciary duties of the board of directors of Parent or by any Legal Requirement; and (2) Parent shall have provided the Company with reasonable advance notice of the content of such disclosure.

(c) Notwithstanding anything to the contrary contained in Section 5.3(b), at any time prior to the approval of the issuance of Parent Common Stock in the Merger by the Required Parent Stockholder Vote, the Parent Board Recommendation may be withdrawn or modified in a manner adverse to the Company if: (i) Parent shall have provided to the Company, at least five business days prior to each meeting of Parent's board of directors at which such board of directors considers the possibility of withdrawing the Parent Board Recommendation or modifying the Parent Board Recommendation in a manner adverse to the Company, written notice of such meeting together with reasonably detailed information regarding the circumstances giving rise to the consideration of such possibility; (ii) Parent's board of directors determines in good faith that: (A) a Company Material Adverse Effect has occurred since the date of this Agreement and is continuing; or (B) since the date of this Agreement, an event has occurred or circumstance exists that, in combination with any other events or circumstances since the date of this Agreement, would reasonably be expected to have or result in a Company Material Adverse Effect; and (iii) Parent's board of directors determines in good faith, after taking into account the advice of Parent's outside legal counsel, that the withdrawal or modification of the Parent Board Recommendation is required in order for Parent's board of directors to comply with its fiduciary obligations to Parent's stockholders under applicable law. Parent shall notify the Company promptly (and in any event within two hours) of: (A) any withdrawal of or modification to the Parent Board Recommendation; and (B) the circumstances surrounding such withdrawal or modification.

A-42

(d) Parent's obligation to call, give notice of and hold the Parent Stockholders' Meeting in accordance with Section 5.3(a) shall not be limited or otherwise affected by any withdrawal or modification of the Parent Board Recommendation.

5.4 Stock Options and Company ESPP.

(a) At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time, whether or not vested, shall be converted into and become an option to purchase Parent Common Stock, and Parent shall either: (i) assume such Company Option (including accepting such Company Option by assignment from the Company); or (ii) replace such Company Option by issuing a materially equivalent replacement stock option to purchase Parent Common Stock in substitution therefor, in either case in accordance with the terms (as in effect as of the date of this Agreement) of the applicable Company Option Plan and/or the terms of the stock option agreement by which such Company Option is evidenced; provided, however, that to the extent permissible under the terms of the applicable Company Option Plan identified on Schedule 5.4(a), and then in accordance with the terms (as in effect as of the date of this Agreement) of such Company Option Plan (including any terms providing for any acceleration of vesting), Parent may determine that any or all of the outstanding Company Options granted under each Company Option Plan identified on Schedule 5.4(a) shall not be so converted and shall not be so assumed or replaced, and in that case shall notify the Company of such determination at least 45 days prior to the date on which the Merger becomes effective. All rights with respect to Company Common Stock under Company Options assumed or replaced by Parent shall thereupon be converted into options to purchase Parent Common Stock, and accordingly, from and after the Effective Time: (A) each Company Option assumed or replaced by Parent may be exercised solely for shares of Parent Common Stock; (B) the number of shares of Parent Common Stock subject to each Company Option so assumed or replaced by Parent shall be determined by multiplying the number of shares of Company Common Stock that were subject to such Company Option immediately prior to the Effective Time by the Exchange Ratio, and rounding the resulting aggregate number down to the nearest whole number of shares of Parent Common Stock; (C) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Option so assumed or replaced by Parent shall be determined by dividing the per share exercise price of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by the Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent; and (D) subject to the terms of the stock option agreement by which such Company Option is evidenced, any restriction on the exercise of any Company Option so assumed or replaced by Parent shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged as a result of the assumption or replacement of such Company Option; provided, however, that, following the Effective Time, Parent's board of directors or a committee thereof shall succeed to the authority and responsibility of the Company's board of directors or any committee thereof with respect to each Company Option so assumed or replaced by Parent.

(b) Parent shall: (i) file with the SEC, no later than 15 days after the date on which the Merger becomes effective, a registration statement on Form S-8 (or any successor form), if available for use by Parent, relating to the shares of Parent Common Stock issuable with respect to the Company Options assumed or replaced by Parent in accordance with Section 5.4(a); (ii) use commercially reasonable efforts to maintain the effectiveness of such registration statement for so long as such assumed or replaced Company Options remain outstanding; and (iii) deliver to each holder of a Company Option that is so assumed or replaced a written notice setting forth: (A) the number of shares of Parent Common Stock

A-43

subject to such Company Option; and (B) the exercise price per share payable to Parent upon the exercise of such Company Option.

(c) At the Effective Time, Parent may (if Parent determines that it desires to do so) assume any or all of the Company Option Plans or merge any such Company Option Plans into any stock option plan of Parent. If Parent elects to so assume or merge any Company Option Plan, then, under such Company Option Plan, Parent shall be entitled to grant stock awards, to the extent permissible under applicable Legal Requirements, using the share reserves of such Company Option Plan as of the Effective Time (including any shares returned to such share reserves as a result of the termination of Company Options that are assumed by Parent pursuant to Section 5.4(a)), except that: (i) stock covered by such awards shall be shares of Parent Common Stock; (ii) all references in such Company Option Plan to a number of shares of Company Common Stock shall be deemed amended to refer instead to a number of shares of Parent Common Stock determined by multiplying the number of referenced shares of Company Common Stock by the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; and (iii) Parent's board of directors or a committee thereof shall succeed to the authority and responsibility of the Company's board of directors or any committee thereof with respect to the administration of such Company Option Plan.

(d) Upon Parent's request, prior to the Effective Time, the Company shall take all actions that may be reasonably necessary for the Company (under the Company Option Plans and otherwise) to effectuate the provisions of this Section 5.4 and to ensure that, from and after the Effective Time, holders of Company Options have no rights with respect thereto other than those specifically provided in this Section 5.4.

(e) Upon Parent's request, prior to the Effective Time, the Company shall take all actions that may be reasonably necessary to: (i) cause any outstanding offering period under the Company ESPP to be terminated as of the last business day prior to the date on which the Merger becomes effective (the last business day prior to the date on which the Merger becomes effective being referred to as the "Designated Date"); (ii) make any pro-rata adjustments that may be necessary to reflect the shortened offering period, but otherwise treat such shortened offering period as a fully effective and completed offering period for all purposes under the Company ESPP; (iii) cause the exercise as of the Designated Date of each outstanding purchase right under the Company ESPP; and (iv) provide that no further offering period or purchase period shall commence under the Company ESPP after the Designated Date; provided, however, that the actions described in clauses "(i)" through "(iv)" of this sentence shall be conditioned upon the consummation of the Merger. On the Designated Date, the Company shall apply the funds credited as of such date under the Company ESPP within each participant's payroll withholding account to the purchase of whole shares of Company Common Stock in accordance with the terms of the Company ESPP. Immediately prior to and effective as of the Effective Time (and subject to the consummation of the Merger), the Company shall terminate the Company ESPP. In the event that the commencement of the next regularly scheduled offering period under the Parent ESPP is more than 90 days after the date on which the Merger becomes effective, Parent will establish a special offering period for Continuing Employees under the Parent ESPP, which period shall commence as soon as administratively practicable following the Effective Time and end on the date immediately prior to the date of commencement of the next regularly scheduled offering period under the Parent ESPP.

5.5 Employee Benefits.

(a) Parent agrees that, subject to any necessary transition period and subject to any applicable plan provisions, contractual requirements or Legal Requirements, all employees of the Acquired Corporations who continue employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation after the Effective Time ("Continuing Employees") will be eligible to participate in: (i) the Parent ESPP and, as determined by Parent, applicable stock option plans of Parent; (ii) Parent's non-equity employee benefit plans and programs, including any profit sharing plan, severance plan, medical plan, dental plan, life insurance plan, time-off programs and disability plan, in each case to substantially the same extent as similarly situated employees of Parent; (iii) such Company Employee Plans as are continued by the Company or any of its Subsidiaries following the Closing Date, or are assumed by Parent (for the purposes of this Section 5.5 only, the plans referred to in clauses "(i)" through "(iii)" of this sentence being referred to as "Specified Parent Benefit Plans"). Each Continuing Employee shall, to the extent permitted by applicable Legal Requirements, receive full credit for purposes of eligibility, vesting, level of benefits and benefit accrual under the Specified Parent Benefit Plans in which such Continuing Employee participates (other than under any sabbatical program or with respect to the vesting of any stock options granted by Parent after the Effective Time) for the years of continuous service by such Continuing Employee recognized by the Acquired Corporations prior to the Effective Time. With respect to any welfare benefit plans maintained by Parent for the benefit of Continuing Employees located in the United States, subject to any applicable plan provisions, contractual requirements or Legal Requirements, Parent shall: (A) cause to be waived, as required by applicable Legal Requirements, any eligibility requirements or pre-existing condition limitations; and (B) give effect, in determining any deductible maximum out-of-pocket limitations, to amounts paid by such Continuing Employees with respect to substantially similar plans maintained by any Acquired Corporation during the plan year in which the Effective Time occurs.

(b) Nothing in this Section 5.5 or elsewhere in this Agreement shall be construed to create a right in any Company Employee to employment with Parent, the Surviving Corporation or any other Subsidiary of Parent. Except for Indemnified Persons (as defined in Section 5.6(a)) to the extent of their respective rights pursuant to Section 5.6, no Company Employee, and no Continuing Employee, shall be deemed to be a third party beneficiary of this Agreement.

(c) If requested by Parent at least five business days prior to the Closing, the Company shall take (or cause to be taken) all actions pursuant to resolutions of the Company's board of directors necessary or appropriate to terminate, effective no later than the day prior to the date on which the Merger becomes effective, any Company Employee Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (a "Company 401(k) Plan"). If the Company is required to terminate any Company 401(k) Plan, then the Company shall provide to Parent prior to the Closing Date written evidence of the adoption by the Company's board of directors of resolutions authorizing the termination of such Company 401(k) Plan (the form and substance of which resolutions shall be subject to the prior review and approval of Parent).

(d) To the extent any employee notification or consultation requirements are imposed by applicable Legal Requirements with respect to any of the Contemplated Transactions, the Company shall cooperate with Parent to ensure that such requirements are complied with prior to the Effective Time. The Company shall use commercially reasonable efforts to obtain and maintain compliance with all applicable rules and regulations of The NASDAQ Stock Market in connection with all matters relating to stock options and employee benefit plans.

5.6 Indemnification of Officers and Directors.

(a) All rights to indemnification by the Company existing in favor of those Persons who are directors and officers of the Company as of the date of this Agreement (the "Indemnified Persons") for their acts and omissions as directors and officers of the Company occurring prior to the Effective Time, as provided in the Company's certificate of incorporation and bylaws (each as in effect as of the date of this Agreement) and as provided in any indemnification agreements between the Company and said Indemnified Persons (as in effect as of the date of this Agreement) identified in Part 2.10(a)(iv) of the Company Disclosure Schedule (or as provided in any currently effective indemnification agreements with any Indemnified Persons that are substantially similar to the agreements identified in Part 2.10(a)(iv) of the Company Disclosure Schedule), shall survive the Merger and be observed by the Surviving Corporation to the fullest extent permitted by Delaware law for a period of six years from the date on which the Merger becomes effective.

(b) From the Effective Time until the sixth anniversary of the date on which the Merger becomes effective, the Surviving Corporation shall maintain in effect, for the benefit of the Indemnified Persons with respect to their acts and omissions as directors and officers of the Company occurring prior to the Effective Time, the existing policy of directors' and officers' liability insurance maintained by the Company as of the date of this Agreement in the form delivered by the Company to Parent prior to the date of this Agreement (the "Existing D&O Policy"), if directors' and officers' liability insurance coverage is available for Parent's directors and officers; provided, however, that: (i) the Surviving Corporation may substitute for the Existing D&O Policy a policy or policies of comparable coverage; and (ii) the Surviving Corporation shall not be required to pay annual premiums for the Existing D&O Policy (or for any substitute policies) in excess of 200% of the annual premium paid by the Company in 2004 with respect to the Existing D&O Policy (the "Maximum Premium"). In the event any future annual premiums for the Existing D&O Policy (or any substitute policies) exceed the Maximum Premium, the Surviving Corporation shall be entitled to reduce the amount of coverage of the Existing D&O Policy (or any substitute policies) to the amount of coverage that can be obtained for a premium equal to the Maximum Premium.

(c) This Section 5.6 is intended to be for the benefit of, and shall be enforceable by, the Indemnified Persons, their heirs and personal representatives and shall be binding on the Surviving Corporation and its successors and assigns, and may not be amended, altered or repealed after the Effective Time without the prior written consent of the affected Indemnified Person (provided that such amendment, alteration or repeal prior to the Effective Time shall be governed by Section 9.1). In the event that the Surviving Corporation or any of its successors or assigns: (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger; or (ii) transfers all or substantially all its properties and assets to any person, then, and in each case, proper provision shall be made so that the successors and assigns of the Surviving Corporation honor the indemnification obligations set forth in this Section 5.6.

(For purposes of this Section 6.14, a Governmental Body shall not be deemed to be a "participant" in a Legal Proceeding if the Legal Proceeding involves only non-governmental parties and the exclusive role played by such Governmental Body in such Legal Proceeding is that of court or judge.)

IRREVOCABLE PROXY

The undersigned stockholder (the "Stockholder") of ADOBE SYSTEMS INCORPORATED, a Delaware corporation ("Parent"), hereby irrevocably (to the fullest extent permitted by law) appoints and constitutes Clint Smith, Betsey Nelson and MACROMEDIA, INC., a Delaware corporation (the "Company"), and each of them, the attorneys and proxies of the Stockholder, with full power of substitution and resubstitution, to the full extent of the Stockholder's rights with respect to the outstanding shares of capital stock of Parent owned of record by the Stockholder as of the date of this proxy, which shares are specified on the final page of this proxy.

PERSONAL AND CONFIDENTIAL

April 17, 2005

Board of Directors
Adobe Systems Incorporated
345 Park Avenue
San Jose, California 95110

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to Adobe Systems Incorporated (the "Company") of the exchange ratio (the "Exchange Ratio") of 0.69 shares of common stock, par value $0.0001 per share (the "Company Common Stock"), of the Company to be issued in exchange for each share of common stock, par value $0.001 per share (the "Macromedia Common Stock"), of Macromedia, Inc. ("Macromedia") pursuant to the Agreement and Plan of Merger and Reorganization, dated as of April 17, 2005 (the "Agreement"), among the Company, Avner Acquisition Sub, Inc., a wholly owned subsidiary of the Company, and Macromedia.

Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the "Transaction"). We expect to receive fees for our services in connection with the Transaction, the principal portion of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. In addition, we have provided certain investment banking services to the Company and Macromedia from time to time. We also may provide investment banking services to the Company and Macromedia in the future. In connection with the above-described investment banking services we have received, and may receive, compensation.

Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, Macromedia and their affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and Macromedia for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

D-1

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and Macromedia for the five fiscal years ended December 3, 2004, in the case of the Company, and March 31, 2004, in the case of Macromedia; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and Macromedia; certain other communications from the Company and Macromedia to their respective stockholders; certain internal financial analyses and forecasts for Macromedia prepared by its management; certain internal financial analyses and forecasts for the Company and certain financial analyses and forecasts for Macromedia prepared by the management of the Company (the "Forecasts"), including certain cost savings and operating synergies projected by the management of the Company to result from the Transaction (the "Synergies"). We also have held discussions with members of the senior managements of the Company and Macromedia regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of the Company and Macromedia. In addition, we have reviewed the reported price and trading activity for the shares of Company Common Stock and the shares of Macromedia Common Stock, compared certain financial and stock market information for the Company and Macromedia with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the software industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the Forecasts, including the Synergies, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company. We also have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or Macromedia or on the expected benefits of the Transaction in any way meaningful to our analysis. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or Macromedia or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, nor are we expressing any opinion as to the prices at which shares of Company Common Stock will trade at any time. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of shares of Company Common Stock should vote with respect to such Transaction.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair from a financial point of view to the Company.

Very truly yours,
/s/ GOLDMAN, SACHS & CO.

(GOLDMAN, SACHS & CO.)

ANNEX E

April 17, 2005

Board of Directors
Macromedia, Inc.
601 Townsend Street
San Francisco, California 94103

Members of the Board:

We understand that Macromedia, Inc. ("Macromedia" or the "Company"), Adobe Systems Incorporated ("Adobe") and Avner Acquisition Sub, Inc. a wholly owned subsidiary of Adobe ("Merger Sub"), propose to enter into an Agreement and Plan of Merger and Reorganization, substantially in the form of the draft dated April 17, 2005 (the "Merger Agreement"), which provides, among other things, for the merger ("Merger") of Merger Sub with and into the Company. Pursuant to the Merger, Macromedia will become a wholly owned subsidiary of Adobe and each outstanding common share, par value $0.001 per share (the "Macromedia Common Stock"), of Macromedia, other than shares held in treasury or held by Adobe, Merger Sub or any wholly-owned subsidiary of Adobe or the Company, will be converted into the right to receive 0.69 ("Exchange Ratio") of a share of common stock, par value $0.0001 per share (the "Adobe Common Stock"), of Adobe. We note that the Exchange Ratio specified above does not reflect the two-for-one stock split announced by Adobe and having a proposed record date of May 2, 2005. Pursuant to the Merger Agreement, the Exchange Ratio will he adjusted accordingly if such split occurs. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to holders of Macromedia Common Stock.

For purposes of the opinion set forth herein, we have:

(i): reviewed certain publicly available financial statements and other business and financial information of Adobe and Macromedia;
(ii): reviewed certain internal financial statements and projections and operating data concerning Adobe and Macromedia, prepared by the managements of Adobe and Macromedia, respectively;
(iii): discussed the past and current operations and financial condition and the prospects of Adobe and Macromedia with senior executives of Adobe and Macromedia, respectively;
(iv): discussed certain strategic, financial and operational benefits anticipated from the Merger with the managements of Adobe and Macromedia;
(v): reviewed the pro forma financial impact of the Merger on the combined company's financial performance, including earnings per share;
(vi): reviewed the reported prices and trading activity for the Adobe Common Stock and the Macromedia Common Stock;
(vii): compared the financial performance of Adobe and Macromedia and the prices and trading activity of Adobe Common Stock and Macromedia Common Stock with that of certain other publicly-traded companies comparable with Adobe and Macromedia, respectively, and their securities;

E-1

(viii): discussed the strategic rationale for the Merger with the management of Adobe and Macromedia, including among other things, certain alternatives to the Merger with the management of Macromedia;
(ix): reviewed the financial terms, to the extent publicly available, of certain comparable acquisition transactions;
(x): participated in discussions and negotiations among representatives of Adobe and Macromedia and their financial and legal advisors;
(xi): reviewed the Merger Agreement and certain related documents; and
(xii): performed such other analyses and considered other such factors as we have deemed appropriate.

We have assumed and relied upon without independent verification the accuracy and completeness of the information reviewed by us for the purposes of this opinion. With respect to the internal financial statements, including information relating to the strategic, financial and operational benefits anticipated from the Merger and assessments regarding the prospects of Adobe and Macromedia, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of Adobe and Macromedia, respectively. In addition, we have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement without material modification, waiver or delay, including, among other things, the Merger will be treated as a tax-free reorganization pursuant to the Internal Revenue Code of 1986, as amended. We have also assumed that in connection with the receipt of all the necessary regulatory approvals for the proposed Merger, no restrictions will be imposed or delays will result that would have a material adverse affect on the contemplated benefits expected to be derived in the proposed Merger. We are not legal or regulatory advisors and have relied upon without independent verification, the assessment by the Company and its legal and regulatory advisors with respect to such matters.

We have relied upon, without independent verification, the assessment by the managements of Adobe and Macromedia of: (i) the strategic, financial and other benefits expected to result from the Merger; (ii) the timing and risks associated with the integration of Adobe and Macromedia; (iii) their ability to retain key employees of Adobe and Macromedia, respectively and (iv) the validity of, and risks associated with, Adobe's and Macromedia's existing and future intellectual property, products, services and business models. We have not made any independent valuation or appraisal of the assets or liabilities of Adobe and Macromedia, nor have we been furnished with any such appraisals. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

We were not authorized to solicit, and did not solicit, interest from any party with respect to the acquisition, business combination or any other extraordinary transaction, involving Macromedia.

We have acted as financial advisor to the Board of Directors of Macromedia in connection with this transaction and will receive a fee for our services. In the past, Morgan Stanley & Co. Incorporated ("Morgan Stanley") and its affiliates have provided financial advisory and financing services for the Company and Adobe and have received fees for the rendering of these services. In the ordinary course of our trading, brokerage, investment management and financing activities, Morgan Stanley or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for our own account or the accounts of customers, in debt or equity securities or senior loans of Adobe, Macromedia or any other company or any currency or commodity that may be involved in this transaction.

E-2

It is understood that this letter is for the information of the Board of Directors of the Company and may not be used for any other purpose without our prior written consent, except that a copy of this opinion may be included in its entirety in any filing the Company is required to make with the Securities and Exchange Commission in connection with this transaction if such inclusion is required by applicable law. In addition, this opinion does not in any manner address the prices at which Macromedia Common Stock and Adobe Common Stock will trade at any time and Morgan Stanley expresses no opinion or recommendation as to how the shareholders of Macromedia should vote at the shareholders' meeting to be held in connection with the Merger.

Based on and subject to the foregoing, we are of the opinion on the date hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to holders of Macromedia Common Stock.

		MORGAN STANLEY & CO. INCORPORATED

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law, Article VI, Part A of Adobe's Restated Certificate of Incorporation, Article XI of Adobe's Amended and Restated Bylaws, and indemnification agreements entered into by Adobe with its directors and officers provide for the indemnification or limitation of liability of officers, directors, employees and agents under certain circumstances.

Set forth below is Article VI, Part A of Adobe's Restated Certificate of Incorporation:

"A. A director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation or law (iii) under Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit. If the Delaware General Corporation Law is amended after approval by the stockholders of this Article to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended."

Set forth below is Article XI of Adobe's Amended and Restated Bylaws:

"ARTICLE XI INDEMNIFICATION. SECTION 43. Indemnification of Directors, Executive Officers, Other Officers, Employees and Other Agents. (a) Directors and Executive Officers. The corporation shall indemnify its directors and executive officers (for the purposes of this Article XI, "executive officers shall have the meaning defined in Rule 3b-7 promulgated under the 1934 Act) to the fullest extent not prohibited by the Delaware General Corporation Law; PROVIDED, HOWEVER, that the corporation may modify the extent of such indemnification by individual contracts with its directors and executive officers; and, PROVIDED, FURTHER, that the corporation shall not be required to indemnify any director or executive officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized by the Board of Directors of the corporation, (iii) such indemnification is provided by the corporation, in its sole discretion, pursuant to the powers vested in the corporation under the Delaware General Corporation Law or (iv) such indemnification is required to be made under subsection (d).

(b) Other Officers, Employees and Other Agents. The corporation shall have power to indemnify its other officers, employees and other agents as set forth in the Delaware General Corporation Law.

(c) Expenses. The corporation shall advance to any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director or executive officer of the corporation, or is or was serving at the request of the corporation as a director or executive officer of another corporation, partnership, joint venture, trust or other enterprise, prior to the final disposition of the proceeding, promptly following request therefor, all expenses incurred by any director or executive officer in connection with such proceeding upon receipt of an undertaking by or on behalf of such person to repay said amounts if it should be determined ultimately that such person is not entitled to be indemnified under this Bylaw or otherwise. Notwithstanding the foregoing, unless otherwise determined pursuant to paragraph (e) of this Bylaw, no advance shall be made by the corporation to an executive officer

II-1

of the corporation (except by reason of the fact that such executive officer is or was a director of the corporation in which event this paragraph shall not apply) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, if a determination is reasonably and promptly made (i) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to the proceeding, or (ii) if such quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, that the facts known to the decision-making party at the time such determination is made demonstrate clearly and convincingly that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation.

(d) Enforcement. Without the necessity of entering into an express contract, all rights to indemnification and advances to directors and executive officers under this Bylaw shall be deemed to be contractual rights and be effective to the same extent and as if provided for in a contract between the corporation and the director or executive officer. Any right to indemnification or advances granted by this Bylaw to a director or executive officer shall be enforceable by or on behalf of the person holding such right in any court of competent jurisdiction if (i) the claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of such claim is made within ninety (90) days of request therefor. The claimant in such enforcement action, if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting his claim. In connection with any claim for indemnification, the corporation shall be entitled to raise as a defense to any such action that the claimant has not met the standards of conduct that make it permissible under the Delaware General Corporation Law for the corporation to indemnify the claimant for the amount claimed. In connection with any claim by an executive officer of the corporation (except in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such executive officer is or was a director of the corporation) for advances, the corporation shall be entitled to raise a defense as to any such action clear and convincing evidence that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation, or with respect to any criminal action or proceeding that such person acted without reasonable cause to believe that his conduct was lawful. Neither the failure of the corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that claimant has not met the applicable standard of conduct. In any suit brought by a director or executive officer to enforce a right to indemnification or to an advancement of expenses hereunder, the burden of proving that the director or executive officer is not entitled to be indemnified, or to such advancement of expenses, under this Article XI or otherwise shall be on the corporation.

(e) Non-Exclusivity of Rights. The rights conferred on any person by this Bylaw shall not be exclusive of any other right which such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding office. The corporation is specifically authorized to enter into individual contracts with any or all of its directors, officers, employees or agents respecting indemnification and advances, to the fullest extent not prohibited by the Delaware General Corporation Law.

(f) Survival of Rights. The rights conferred on any person by this Bylaw shall continue as to a person who has ceased to be a director, officer, employee or other agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

II-2

(g) Insurance. To the fullest extent permitted by the Delaware General Corporation Law, the corporation, upon approval by the Board of Directors, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to this Bylaw.

(h) Amendments. Any repeal or modification of this Bylaw shall only be prospective and shall not affect the rights under this Bylaw in effect at the time of the alleged occurrence of any action or omission to act that is the cause of any proceeding against any agent of the corporation.

(i) Saving Clause. If this Bylaw or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each director and executive officer to the full extent not prohibited by any applicable portion of this Bylaw that shall not have been invalidated, or by any other applicable law.

(j) Certain Definitions. For the purposes of this Bylaw, the following definitions shall apply:

(i) The term "proceeding" shall be broadly construed and shall include, without limitation, the investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the giving of testimony in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative.

(ii) The term "expenses" shall be broadly construed and shall include, without limitation, court costs, attorneys' fees, witness fees, fines, amounts paid in settlement or judgment and any other costs and expenses of any nature or kind incurred in connection with any proceeding.

(iii) The term the "corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Bylaw with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

(iv) References to a "director," "executive officer," "officer," "employee," or "agent" of the corporation shall include, without limitation, situations where such person is serving at the request of the corporation as, respectively, a director, executive officer, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust or other enterprise.

Financial Statement Schedules

Item 22. Undertakings.

The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a) (3) of the Securities Act of 1933;

II-5

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(5) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request;

(6) That, prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form;

(7) That every prospectus (i) that is filed pursuant to paragraph (6) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

II-6

(8) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

II-7
