The Company's annual report for the fiscal year ended December 31, 2005, accompanies this Proxy Statement. The annual report is not proxy soliciting material, nor is it incorporated herein by reference.

ABOUT THE MEETING

Q:		What is the purpose of the Annual Meeting?
A:		At the Annual Meeting, the Company's stockholders will be asked to vote on the matters listed in the accompanying notice of annual meeting, namely:
		* the election of Messrs. James W. Crownover, Roger L. Headrick, Leo I. Higdon, Jr. and Jay D. Proops as directors;
		* a proposal to amend the Company's Amended and Restated Certificate of Incorporation;
		* the approval of the 2006 Chemtura Corporation Long-Term Incentive Plan; and
		* the ratification of KPMG LLP as the Company's independent auditor for 2006.
		Stockholders will also transact such other business that may properly come before the meeting. The Company's management will be present at the meeting to report on the Company's performance during 2005 and will answer stockholder questions.

Q:		Who is entitled to vote?
A:		Stockholders as of the close of business on the record date, February 27, 2006, are entitled to vote their shares of the Company's common stock. Each outstanding share of common stock is entitled to one vote. At the close of business on the record date, there were 240,135,026 shares of the Company's common stock outstanding. The Company has no other voting securities issued and outstanding.

Q:		How many shares must be present to hold the meeting?
A:		A quorum must be present at the meeting for business to be conducted. A quorum is reached when there are present at the meeting, in person or by proxy, the holders of a majority of the shares of the Company's common stock outstanding on the record date. Abstentions and withhold-authority votes will be included for purposes of determining a quorum and for purposes of calculating the vote, but will not be considered to have been voted in favor of the item voted upon. Broker non-votes will be included for purposes of determining a quorum, but will not be considered to be represented at the meeting for purposes of calculating the vote, and thus, they will not affect the outcome of any proposal.

Q:		What if a quorum is not present at the meeting?
A:		If a quorum is not present at the time of the meeting, the stockholders who are represented may adjourn the meeting until a quorum is present. The time and place of the adjourned meeting will be announced at the time the adjournment is taken, and no other notice will be given.

Q:		How do I vote?
A:		You may vote in any of three ways:
		* You may vote by mail if you complete, sign and date the accompanying proxy card and return it in the prepaid envelope. Your shares will be voted confidentially and in accordance with your instructions;
		* You may vote by telephone or via the Internet in accordance with the instructions found on your proxy card; and
		* You may vote in person if you are a registered stockholder and attend the meeting and deliver your completed proxy card in person. At the meeting, the Company will also distribute written ballots to registered stockholders who wish to vote in person at the meeting. Beneficial owners of shares held in "street name" who wish to vote at the meeting will need to obtain a proxy form from the institution that holds their shares.

Q:		How many votes does it take to approve the items to be voted upon?
A:		Directors are elected by a plurality of votes. This means that, assuming a quorum is present at the meeting, director nominees will be elected if the nominees receive the greatest number of affirmative votes cast for the election of directors. The affirmative vote of the holders of eighty (80%) percent of the outstanding shares of the Company is needed to approve the amendment to the Company's Amended and Restated Certificate of Incorporation. The affirmative vote of a majority of the shares having voting power present in person or represented by proxy at the meeting is needed to approve the 2006 Chemtura Corporation Long-Term Incentive Plan and to ratify the selection of KPMG LLP as the Company's independent auditors for 2006.

Q:		Can I revoke my proxy before it is exercised?
A:		Yes, you may revoke your proxy and change your vote at any time before the polls close at the meeting by using any of the following methods:
		* by signing another proxy with a later date;
		* by voting by telephone or via the Internet after the date and time of your last telephone or Internet vote; or
		* if you are a registered stockholder, by giving written notice of such revocation to the Secretary of the Company prior to or at the meeting or by voting in person at the meeting.
		Attendance at the meeting will not automatically revoke a previously granted proxy.

Q:		Who will count the votes?
A:		The Company's transfer agent, Mellon Investor Services LLC, will tabulate and certify the votes and act as inspector of election at the meeting.

Q:		How are shares in the Chemtura Employee Savings Plan, Chemtura Employee Stock Purchase Plan and Chemtura Dividend Reinvestment Plan voted?
A:		The shares of Company common stock held by the trustee under the Chemtura Employee Savings Plan and in each employee's account under the Chemtura Employee Stock Purchase Plan and Chemtura Dividend Reinvestment Plan will be voted according to each employee's voting instructions. If no instructions are received, the shares in the Chemtura Employee Savings Plan and Chemtura Employee Stock Purchase Plan will not be voted while an individual's shares in the Chemtura Dividend Reinvestment Plan will be voted in the same manner that such person's shares held of record are voted.

Q:		Who is soliciting my vote and who pays the cost?
A:		The Company has retained Mellon Investor Services LLC to assist in the distribution of proxy materials and the solicitation of votes for a fee of $5,000, excluding out-of-pocket expenses. The Company will pay the entire cost of the solicitation and will reimburse banks, brokerage firms, custodians, nominees and fiduciaries for their reasonable expenses in sending proxy materials to the beneficial owners of the Company stock. Proxies may be solicited personally, by mail, by telephone, by facsimile or by telegraph, by the directors, officers or other employees of the Company, without remuneration other than regular compensation.

Q:		When are the year 2007 stockholder proposals due?
A:		If a stockholder wants a proposal to be included in the Company's proxy statement for the 2007 annual meeting of stockholders, the proposal, in writing and addressed to the Company's Secretary, must be received by the Company no later than December 4, 2006. If a stockholder wishes to recommend nominees to the Board of Directors, or to bring other business before the 2007 annual meeting, the proposal, in writing and addressed to the Company's Secretary, must be received by the Company no later than January 27, 2007, or not later than ten days after notice of the date of the 2007 annual meeting is given to stockholders, whichever date is earlier.

CORPORATE GOVERNANCE

Role of the Board of Directors

The Board of Directors of the Company is elected by the stockholders with the responsibility to oversee and direct the management of the Company so as to enhance stockholder value. The Board works with management to select and approve a corporate philosophy and mission, and in connection therewith the Board reviews, approves and monitors management's strategic and business plans and the Company's financial objectives, plans and actions. The Board approves the Company's material transactions, significant capital allocations and expenditures and measures the performance of management in relation to the performance of peer companies and the specialty chemical industry as a whole. The Board also periodically reviews the performance of the Chief Executive Officer.

The Board adopts policies of corporate conduct, including compliance with applicable laws and regulations, auditing and accounting principles and financial controls, and the Company's own governing documents. The Board assesses its own effectiveness in fulfilling these and other Board responsibilities and performs such other functions as are prescribed by law or assigned to the Board in the Company's governing documents.

Role of the Organization, Compensation and Governance Committee

The Organization, Compensation and Governance Committee makes recommendations to the Board with respect to the organization, size and composition of the Board, including the assignment of directors to committees and committee chairmanships. The Committee identifies suitable candidates for Board membership, reviews their qualifications and proposes a slate of directors for election by the stockholders at each annual meeting.

The Organization, Compensation and Governance Committee also makes an annual assessment of the performance of the Board, reviews the Board's Corporate Governance Principles, recommends with the advice of an outside compensation consultant the compensation of directors, the Chief Executive Officer and other senior management, and advises the Board with respect to the selection and performance of the Chief Executive Officer. The Committee assists the Board in providing for orderly succession of the top management of the Company.

The Audit Committee also selects the independent auditor after discussion with the Board, evaluates the auditor's qualifications, independence and performance, has responsibility for approving all audit and non-audit services provided by the independent auditor, considers the possible effect of providing such non-audit services on the auditor's independence, and reviews the range of fees of the auditor for both audit and non-audit services.

The Audit Committee also reviews earnings press releases and financial information and earnings guidance provided to rating agencies, establishes procedures for handling complaints about accounting and auditing matters, and periodically reviews the Company's Code of Business Conduct and Ethics.

The separately designated standing Audit Committee is established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (the "Exchange Act"), and the members of the Audit Committee are listed in the above table.

The Board of Directors has determined that Mr. Bruce F. Wesson, the Chairman of the Audit Committee, meets the requirements of audit committee financial expert and that Mr. Wesson is independent under applicable NYSE and Securities and Exchange Commission rules.

The Organization, Compensation and Governance Committee is responsible for the administration of the Company's compensation plans, including approval of the level of compensation for senior executive officers named in the proxy statement and adoption of bonus and deferred compensation plans and arrangements for executive officers. The Committee reviews and approves the corporate goals and objectives relevant to the Chief Executive Officer's compensation and sets his compensation based on this evaluation. The Committee also makes recommendations with respect to the organization, size and composition of the Board, identifies suitable candidates for Board membership and reviews their qualifications, proposes a slate of directors for election by the stockholders at each annual meeting, and assists the Board in providing for orderly succession of the top management of the Company. The Committee makes an annual assessment of the performance of the Board and reviews its Corporate Governance Principles.

The Finance and Pension Committee has the authority, which it may exercise when the Board is not in session, to approve certain debt financings and reviews and makes recommendations to the Board regarding the issuance or reacquisition of securities, major debt financings, capital expenditures, acquisitions, divestitures and other expenditures, dividend policy, management of pension assets, and risk management policy and strategy.

The Safety, Health and Environment Committee provides guidance to and oversight of management with respect to safety, health and environmental matters, including the review of the Company's safety, health and environmental performance, policies, standards, procedures, management systems and strategic plans. The Committee also recommends actions and policies that will enable the Company to achieve a high level of safety, health and environmental performance compared with its peers in the chemical industry and to maintain good relations with the Company's neighbors.

Stockholder Recommendations of Director Nominees

The Organization, Compensation and Governance Committee will consider qualified candidates recommended by stockholders for Board membership in

accordance with the procedure set forth in the Company's By-laws. Any stockholder entitled to vote in the election of directors may recommend one or more persons for election as a director at a meeting if written notice of such stockholder's intent to make such recommendation or recommendations has been given, either by personal delivery or by mail, postage prepaid, to the Secretary of the Company not later than 90 days prior to the anniversary date of the immediately preceding annual meeting or the close of business on the tenth day following the date on which notice of such meeting is first given to stockholders, whichever is earlier. Notwithstanding the foregoing sentence, in the event that the number of directors to be elected to the Board is increased and there is no public announcement by the Company naming all of the nominees or specifying the size of the increased Board at least 70 days prior to the first anniversary of the preceding year's annual meeting, a stockholder's notice shall be considered timely, but only with respect to nominees for new positions created by such increase, if delivered to the Secretary not later than the close of business on the tenth day following the date on which such public announcement is first made by the Company. Each such notice shall set forth (i) the name and address of the stockholder who intends to make the recommendation and of the person or persons to be recommended; (ii) a representation that the stockholder is a holder of record of stock of the Company entitled to vote at such meeting having a value of at least $1,000 and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (iii) a description of all arrangements or undertakings between the stockholder and each recommended nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder; (iv) such other information regarding each nominee recommended by such stockholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission; and (v) the consent of each recommended nominee to serve as a director of the Company, if so elected. The candidates recommended by stockholders will receive the same consideration that candidates recommended by the Committee will receive.

The Company's Corporate Governance Principles require that all candidates for Board membership, whether proposed by a stockholder or otherwise, possess the following qualifications: (i) unquestionable personal and professional ethics and integrity; (ii) policy-making experience in business, education, technology or government; (iii) expertise that is useful to the Company and complementary to that of other Board members; (iv) a willingness to serve on the Board for a period of at least several years and to devote the time required to meet the responsibilities and perform the duties of a director, including attendance at all Board and applicable committee meetings; (v) a commitment to represent the best interests of all stockholders and to objectively appraise the performance of the Company and of management; and (vi) involvement only in activities that do not create a conflict with the director's responsibilities to the Company and its stockholders. The Company uses an outside consultant to assist in identifying and evaluating potential nominees to the Board.

REPORT OF THE ORGANIZATION,
COMPENSATION AND GOVERNANCE COMMITTEE

Role of the Organization, Compensation and Governance Committee in Corporate Governance

The Organization, Compensation and Governance Committee of the Board of Directors (the "Committee") makes recommendations to the Board with respect to the organization, size and composition of the Board, including the assignment of directors to committees and committee chairmanships. The Committee identifies suitable candidates for Board membership, reviews their qualifications and proposes a slate of directors for election by the stockholders at each annual meeting.

The Committee makes an annual assessment of the performance of the Board and reviews the Board's Corporate Governance Principles, recommends with the

advice of an outside compensation consultant the compensation of directors, the Chief Executive Officer and other executive officers, and advises the Board with respect to the selection and performance of the Chief Executive Officer. The Committee, consisting entirely of outside directors, establishes Company performance goals, base salary pay levels and target annual bonus awards, approves annual bonus payments and establishes and approves long-term incentives for the executive officers of the Company. The Committee assists the Board in providing for the orderly succession in the top management of the Company.

Executive Compensation Philosophy

The compensation program for the Company's executive officers is administered consistent with a pay for performance philosophy designed to link executive compensation with the values, objectives, business strategy, management initiatives and financial performance of the Company. In addition, a significant portion of each executive officer's compensation is realized upon the creation of shareholder value.

The goals of the Company's executive compensation program are to (i) attract and retain talented executives; (ii) motivate executives to deliver strong business results in line with shareholder expectations; (iii) foster and drive a results oriented culture; and (iv) align executive interests with shareholder interests by encouraging executives to earn and own Company stock.

The compensation of the Company's executive officers comprises cash (salary and bonus) and equity (stock and stock options) components and is designed to be competitive and highly leveraged based upon corporate financial performance and shareholder return. The compensation program targets are at the median (50^th percentile) of the competitive market for base salary, annual variable compensation and longer-term variable compensation. The target levels of annual variable compensation (bonus) are calibrated with challenging but achievable performance goals. The Committee emphatically believes in differentiation in pay based on performance, for all types of compensation, including individual salary levels, annual variable compensation and longer-term variable compensation. The relationship between pay and performance is leveraged, and an executive officer's performance which significantly exceeds expectations will be rewarded with incentive pay well above competitive levels (i.e., at the 75^th percentile or above). Similarly, performance that does not meet the Company's plans or its commitments to its investors, employees or its communities, will reduce incentive payments substantially (i.e., between 50 percent of target and zero).

The Committee believes that stock ownership by management and performance compensation plans based on Company stock aligns the interests of management and other stockholders in the enhancement of shareholder value. To that end, executive officers are encouraged to retain the shares they earn through the compensation programs.

Executive Compensation Practices

The Committee uses the services of an outside compensation consultant to obtain independent advice and to review the competitiveness of the Company's compensation program. The competitive data is drawn from broad external data and the consultant's database that it considers as an appropriate group of companies against which to compare the Company for compensation purposes. For purposes of shareholder return comparisons elsewhere in this Proxy Statement, the Committee uses an index focused on the Specialty Chemicals industry, based on its belief that an industry index is an appropriate peer group for investment comparisons. The companies chosen for the shareholder return comparisons are not necessarily those represented in the compensation comparator group. The Committee believes that the Company's competitors for executive talent are a broader group of companies and not limited only to the companies in the investment comparison.

Components of Executive Compensation

Executive compensation is composed of a cash base salary, cash bonus annual incentive pay and long-term pay in the form of equity in Chemtura. The long-term pay is in the form of performance based restricted stock and stock options. A summary of each type of compensation is provided below.

Salary

Base salaries for each of the executive officers are set relative to the external competitive salary range for their role and reviewed annually based on Chemtura's executive compensation philosophy, changes in the external market for executive talent and demonstrated individual performance. At the January 2005 meeting, the Committee reviewed the base salaries of each of the executive officers in comparison to broad external market data and the size adjusted salaries paid for comparable jobs in the comparator group. Generally, the Committee found that the salaries of executive officers were within the competitive salary range as determined by the external compensation consultant. The Committee approved salary adjustments for the executive officers based on their individual performance and their salaries relative to the external market.

Annual Performance Based Compensation

Annual performance based compensation in the form of cash bonus compensation is designed to reward eligible executives based on their performance relative to business plan. Each executive has a target level of annual performance based compensation as a percentage of base salary that is set on the basis of competitive external levels. Using the target level as a starting point, actual awards are determined by corporate, business or unit and individual results. For 2005, actual rewards for the named executives were funded by the Committee at 70% of target level. Mr. Wood recommended proposed performance awards for the executive

officers other than himself, for the Committee's review and approval. The Committee set an actual performance award for Mr. Wood. Details on how the rewards were determined and the basis for determining funding for this group and individual award levels is provided below.

In 2005, the Company made bold moves toward building long-term success and stability. On July 1, Crompton Corporation acquired Great Lakes Chemical Corporation and formed Chemtura Corporation. The Company made significant progress in reducing its most costly debt and succeeded in resolving its government related legal issues pertaining to antitrust matters. The Company generated improved business results with pricing discipline and improved earnings and cash flow, despite significantly higher raw material and energy costs. The Company continues to restructure its business portfolio to focus resources on its core businesses. The Company restructured its organization to take advantage of synergies from the combining of the two companies, to eliminate work and to reduce the number of positions in the Company in the interests of effectiveness and efficiency. The Company's management made significant progress in improving performance at the Company in 2005 and positioning the business for future favorable performance.

In spite of its progress in resolving business and legal issues, the Company did not fully meet financial goals established for 2005 under the 2005 Management Incentive Plan. After consideration, the Committee agreed to fund performance awards based on the dramatic improvement in year-over-year results from 2004 to 2005. On the basis of the overall performance during 2005, the Committee separately established a reduced bonus pool of 90% of the original target bonus pool for non-executive officer participants based on the Company's level of results described above. In combination with the 2005 Management Incentive Plan awards, the Committee awarded 2005 annual variable incentives for the executive officers at a range of 65% to 97% of the target. The Committee recognized Mr. Wood's consistent extraordinary leadership and outstanding progress in building our Company with a bonus of $610,000 based on the foregoing considerations.

Long-Term Compensation: Equity and Stock Ownership

The Committee believes that long-term incentives should mainly be in the form of equity, which focuses executives on the total performance of the Company in the eyes of the investors and rewards executives when investors are rewarded. Stock options and restricted stock are and will be the Company's primary devices for providing equity ownership opportunities and for focusing executives on long-term financial performance. In 2005, the Committee granted stock options and performance based restricted stock to executive officers. The non-qualified options were granted at the fair market value on the day of grant and vest one-third in each of February 2006, 2007, and 2008 and have a ten year and one month term. The Committee granted a group of executive officers performance based restricted stock in February 2005. This stock is scheduled to vest upon accomplishment and maintenance of prescribed values

for Chemtura stock. The performance based restricted stock vests upon achievement and maintenance of designated Chemtura share values that are realized and maintained for a period of time. Shares earned under this program will pay out in 2007 and 2008. Based on target stock values realized and maintained for ten consecutive trading days in 2005, 40% of the restricted stock grant is scheduled to vest in 2007. Depending on the share value in 2006 and 2007 relative to preset targets, additional shares may be scheduled to vest in 2007 or 2008.

The Committee believes it is important that executives be owners of the Company and maintain significant levels of share ownership in the Company. The Company's guidelines support this principle and the Committee will review them periodically to ensure they are appropriate given prevailing marketplace conditions. The Company has adopted stock ownership goals for its executive officers which range from five times the salary for the Chief Executive Officer to one, two or three times the salary for the remaining executive officers.

The Committee will regularly review the group of employees who are eligible to receive annual stock options or other equity grants. The Committee believes that participation in these programs is primarily for executives and other Company leaders, but the Committee recognizes that it may be appropriate to grant options and restricted stock on a limited basis to reward performance and leadership to other employees or for purposes of attracting or retaining individual employees.

Tax Deductibility of Executive Compensation

The Committee's policy on the tax deductibility of compensation is to maximize deductibility to the extent possible without abdicating all of its discretionary power. To this end, the Committee has submitted qualified plans to stockholders, however, the Committee has occasionally taken actions that result in non-deductible compensation and may do so again in the future when it determines that such actions are in the Company's best interests. During 2005, shareholders approved the Chemtura (Crompton) Corporation 2005 Short-Term Incentive Plan, a plan qualified under Section 162(m) of the Internal Revenue Code and designed to maximize the deductibility of performance-based compensation.

Compensation of Chief Executive Officer

The Committee reviews and approves the corporate goals and objectives relevant to the Chief Executive Officer's compensation and annually evaluates the Chief Executive Officer's performance in light of those goals and objectives. In 2005, the base salary, incentive compensation, stock option and restricted stock awards for the Chief Executive Officer were determined by the Board of Directors based on the recommendations of the Committee using the principles outlined above. Mr. Wood received a base salary of $870,000 during 2005. In addition, Mr. Wood received non-qualified stock options for 300,000 shares and 100,000 shares of performance based restricted stock. The stock options were granted at the market value on the day

of grant and vest in equal parts over three years. The performance based restricted stock vests upon achievement and maintenance of designated Chemtura share values that are realized and maintained for a period of time. Shares earned under this program will pay out in 2007 and 2008. Based on target stock values realized and maintained for ten consecutive trading days in 2005, 40% of the restricted stock grant is scheduled to vest in 2007. Depending on the share value in 2006 and 2007 relative to preset targets, additional shares may vest in 2007 or 2008.

Organization, Compensation and Governance Committee

Decisions on compensation of the Company's executive officers are made by the Organization, Compensation and Governance Committee, a committee of the Board of Directors composed of the persons listed below, all of whom are non-employee directors and are independent, as such term is defined in the New York Stock Exchange listing standards. The Committee has retained an independent executive compensation consultant who has access to independent compensation data to evaluate the Company's executive compensation program.

A copy of the written charter of the Organization, Compensation and Governance Committee is attached as Appendix A to this Proxy Statement. A copy of the charter is also available on the Company's website at www.chemtura.com.

Compensation Committee Interlocks and Insider Participation

Messrs. Andrews, Crownover, Higdon, Jr. and Piccolo served as members and Mr. Headrick served as Chairman of the Organization, Compensation and Governance Committee during the last completed fiscal year. No member of the Organization, Compensation and Governance Committee is a current or former officer or employee of the Company or any of its subsidiaries.

Retirement Plans

The Company provides a retirement plan to most of its United States based employees in the form of a 401(k) plan that includes a three (3%) percent Company contribution, regardless of employee contribution, and a dollar-for-dollar Company matching contribution for the first six (6%) percent of employee contributions. The named executive officers participate in the same program that is made available broadly to United States based Company employees.

The Company also provides to a limited number of officers, including the named executive officers, deferred compensation and benefits under the Company's Supplemental Savings Plan. The compensation and benefits provided are substantially equivalent to those they would have received under the qualified plans of the Company in which they participate, in the absence of certain limitations on contributions and benefits which are imposed by the Internal Revenue Code of 1986, as amended. The amount of these benefits is set forth in the All Other Compensation table under the heading "Supplemental Savings Plan" on page 29.

Employment and Related Agreements

Employment Agreement with Robert L. Wood. Mr. Wood is employed pursuant to an employment agreement which was entered into in January 2004. The agreement provides for Mr. Wood's employment as President and Chief Executive Officer for a term of three years, with automatic annual one-year extensions of the term unless the Company gives notice at least 60 days prior to the anniversary of the date of the agreement that the term will not be extended.

The agreement calls for a base salary of not less than $780,000 and for Mr. Wood's participation in employee benefit plans and other fringe benefit arrangements. In the event Mr. Wood's employment is terminated by the Company without cause (as defined in the agreement), or terminated by Mr. Wood upon the Company's continued and material breach, which breach is not cured within thirty (30) days of the Company receiving written notice of breach, the Company's obligations shall consist of: (1) the payment over the course of normal pay periods to Mr. Wood of his salary for the lesser of a period of two years following the date of termination, or through the end of the then-current term; (2) the payment to Mr. Wood, over the course of normal pay periods, of his annual incentive bonus, with Mr. Wood being deemed to have met targets for the lesser of a period of two years following the date of termination, or through the end of the then-current term; and (3) continuation at Company cost of the other benefits provided to Mr. Wood under the agreement for the lesser of a period of two years following the date of termination, or through the end of the then-current term.

Employment Agreements with Karen R. Osar and Lynn A. Schefsky. The Company has entered into employment agreements with certain other key management employees, including Ms. Osar and Mr. Schefsky. Each agreement is operative upon

the occurrence of a change in control (as defined in the agreement) and is intended to encourage the executive to remain in the employ of the Company by providing the executive with greater employment security. Absent a change in control, the agreements do not require the Company to retain the executive or to pay the executive any specified level of compensation or benefits.

In the event of a change in control, the agreements provide that there will be no change, without the executive's consent, in the salary, bonus opportunity, benefits, duties, and location of employment of the executive for a period of two years after the change in control. If, during such period, the executive's employment is terminated by the Company other than for cause, disability, or death or the executive resigns for good reason (as defined in the agreements), the Company will pay the executive his or her salary to the date of termination, incentive compensation in an amount no less than the bonus paid to the executive for the prior year pro-rated to that date, and a lump sum severance payment equal to two times the sum of the executive's base salary and the highest bonus paid to the executive during the two years preceding the executive's termination and will continue other employee benefits similar to those provided to the executive prior to the executive's termination for a period of two years or until the executive's earlier employment with another employer.

Compensation of Directors

Members of the Board who are not employees of the Company receive the following annual fees for their services:

* an annual retainer fee, including meeting fees, of $67,000 (Audit Committee members receive an additional fee of $5,000);

* each committee chairman receives an additional $8,000, except the Audit Committee chairman who receives an additional $18,000;

* each co-lead director receives an additional $25,000; and

* each director receives an annual stock grant of restricted stock units with a value at date of grant of $75,000 to be settled upon each director's termination of service on the Board of Directors.

Directors are reimbursed for expenses incurred in attending meetings. In addition, the Company provides accidental death and travel insurance coverage for each non-employee director.

Directors who are employees of the Company receive no additional compensation for services on the Board of Directors.

APPROVAL OF AN AMENDMENT
TO THE AMENDED AND RESTATED
CERTIFICATE OF INCORPORATION TO DECLASSIFY THE BOARD

Article VII of the Company's Amended and Restated Certificate of Incorporation (the "Certificate") currently provides that the Board of Directors of the Company be divided into three classes of approximately equal size, composed of directors each serving terms of office of three years. In January 2006, the Board voted to approve, and to recommend to the stockholders that they approve, a proposal to amend the Certificate to phase out the classification of the Board and to provide instead for the annual election of all directors.

If the proposal is approved by the stockholders, those directors previously elected for three-year terms of office will complete their three-year terms, and would be eligible for re-election thereafter for one-year terms at each Annual Meeting of Stockholders. Beginning with the Annual Meeting of Stockholders in 2009, the declassification of the Board would be complete and all directors would be subject to annual election to one-year terms.

The complete text of the proposed amendment, which would amend Sections 1 and 2 of Article VII of the Company's Amended and Restated Certificate of Incorporation is attached hereto as Appendix C to this Proxy Statement.

Classified boards provide effective protection against unwanted takeovers and proxy contests because they make it difficult for a substantial stockholder to gain control of the board without the cooperation or approval of the incumbent directors. A classified board is an effective tool in the hands of a conscientious board, to provide time and opportunity to exercise its fiduciary obligations to maximize shareholder value in responding to a hostile acquisition proposal.

It has been suggested that annual elections increase the board's accountability to shareholders and that classified boards limit the ability of stockholders to evaluate and elect each director each year. Moreover, many commentators believe that the election of directors is the primary means for stockholders to influence corporate governance policies and to hold management accountable for implementing those policies.

The Board considered the arguments in favor and against continuation of the classified Board, listened to the views of stockholders and others concerning this matter and determined that it is in the best interests of the Company and its stockholders to eliminate its classified Board as proposed.

The Board of Directors recommends a vote FOR approval of this proposal, and unless otherwise directed, proxies will be voted in favor of this selection. The affirmative vote of the holders of eighty (80%) percent of the outstanding shares of the Company is required for such approval.

APPROVAL OF THE
2006 CHEMTURA CORPORATION
LONG-TERM INCENTIVE PLAN

The Board of Directors has adopted the 2006 Chemtura Corporation Long-Term Incentive Plan (the "Plan"), subject to approval by the stockholders. The purpose of the Plan is to advance the interests of the Company and its stockholders by (i) providing incentives and rewards to those directors, officers, other employees and service providers who are in a position to contribute to the long-term growth and profitability of the Company; (ii) assisting the Company in attracting, retaining and developing highly qualified employees; and (iii) making the Company's compensation program competitive with those of other major employers. As used in this section of the Proxy Statement, the term "Company" includes Chemtura Corporation and its subsidiaries and affiliates except where otherwise required by the context.

The following is a summary of certain material features of the Plan and is qualified in its entirety by reference to its full text, a copy of which is attached as Appendix D to this proxy statement. Stockholders are urged to read the Plan in its entirety before casting their votes.

Administration. The Plan is administered by the Organization, Compensation and Governance Committee of the Board of Directors or such other committee as may be appointed by the Board of Directors for the purpose of administering the Plan (the "Committee"). The Committee shall determine which eligible individuals shall receive awards under the Plan as well as the amount, terms and conditions of awards, including any performance conditions and conditions relating to the awards' exercisability, vesting, and payment or settlement. The Committee shall also establish the rules for administering and interpreting the Plan. The Committee may delegate to one or more senior executives of the Company the authority to grant awards to individuals other than executive officers as well as administrative responsibilities. With respect to awards made to any non-employee director, the Board of Directors shall serve as the Committee.

Types of Awards. The Plan permits the granting of incentive stock options ("ISOs") as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), stock options not qualifying as ISOs ("nonqualified stock options"), stock, restricted stock, stock appreciation rights ("SARs"), stock units, performance awards, dividend equivalents, and other awards. The Committee, in its

discretion, may also make a cash payment to a participant granted stock or restricted stock to satisfy tax obligations arising out of such award. Each award will be evidenced by an award agreement setting forth the terms of the award.

Shares Subject to the Plan. The maximum number of shares of common stock of the Company ("Stock") that may be issued or transferred to participants under the Plan is 10,500,000, which also represents the maximum number of shares of Stock with respect to which ISOs may be granted. The combined number of shares granted under the Plan pursuant to awards other than stock options and SARs is limited to 33% of the total maximum number of shares available for award under the Plan. Shares that have been forfeited or lapse under the Plan and shares deliverable pursuant to an award that has terminated in accordance with its terms or has been canceled by the participant or the Company do not count toward the aggregate share limit, but shares of Stock subject to SARs do count toward that limit.

Eligibility. Employees of the Company who, in the Committee's opinion, are responsible for or contribute to the management, growth, and profitability of the Company's business are eligible to participate in the Plan. The Company's non-employee directors and other individuals who perform services for the Company are eligible to be granted awards other than ISOs.

Award Limits. No participant may be granted in any calendar year awards that relate to more than 25% of the shares reserved for issuance under the Plan, and no more than 300,000 shares pursuant to any performance awards may be granted to one individual in a calendar year unless pursuant to a multi-year award.

Vesting Limitations. No award (other than an award granted to a non-employee director) may vest earlier than one year from the date of grant. In general, no restricted stock award may vest earlier than three years from the date of grant unless it replaces a restricted stock grant of the participant's prior employer, in which case the vesting of the award may be subject to such shorter period as the Committee determines in its discretion. If vesting of restricted stock is based on performance criteria, however, the minimum vesting period shall be two years from the date of grant.

Awards to non-employee directors. Any awards granted to non-employee directors shall be granted on a non-discretionary basis based on a formula approved by the Committee.

Adjustments in the Event of Certain Corporate Changes. In the event of any change in the outstanding shares of Stock by reason of any stock split, stock dividend, recapitalization, merger, consolidation, combination or exchange of shares or other similar corporate change or in the event of any special distribution to the stockholders, the Committee shall make such equitable adjustments as it deems necessary and appropriate in the number of shares and prices per share applicable to options then outstanding and in the number of shares available thereafter for other

awards, both under the Plan as a whole and with respect to individuals and award type. In addition, the Committee is authorized to make adjustments in the terms and conditions of, and the criteria included in, awards (including cancellation of awards in exchange for the intrinsic (i.e., in-the-money) value, if any, of the vested portion thereof, substitution of awards using securities or other obligations of a successor or other entity, acceleration of the expiration date for awards, or adjustment to performance goals in respect of awards) in recognition of unusual or nonrecurring events (including events described in the preceding sentence, as well as acquisitions and dispositions of businesses and assets) affecting the Company, the financial statements of the Company, or in response to changes in applicable laws, regulations, or accounting principles.

Terms and Conditions of Options. The exercise price of an option or SAR is determined by the Committee when it is granted, but may not be less than the fair market value of the Stock on the date of grant. The exercise price of an ISO granted to a 10% shareholder of the Company may not be less than 110% of the fair market value of the Stock on the date of grant. "Fair market value" is generally the average of the high and low trading prices of a share of the Stock on the New York Stock Exchange on the date as of which the Stock is being valued. The Committee may not grant dividend equivalent rights with respect to options.

The term of an option may not exceed 10 years and the term of an ISO granted to a 10% shareholder of the Company may not exceed five years. The aggregate market value (determined as of the date of grant) of all shares of Stock with respect to which ISOs are exercisable for the first time by a participant in a given calendar year shall not exceed $100,000.

An option may be exercised by delivery of written notice to the Company in accordance with the Company's procedures. An option vests and becomes exercisable according to the terms specified in the award agreement (but not less than one year following the grant date). An option will in any event vest and become exercisable as follows: If a participant's employment or service terminates by reason of death, an option may be exercised, to the extent then exercisable, for a period of two years from the date of death or until the expiration of the stated term of such option, whichever period is shorter. If a participant's employment or service terminates by reason of disability, any option held by such participant may thereafter be exercised (to the extent it was exercisable at the time of termination) for a period of two years from the date of such termination of employment or service or until the expiration of the stated term of such option, whichever period is shorter. If the holder of the option dies while any such option remains exercisable, however, any unexercised option so held at death shall continue to be exercisable (to the extent it was exercisable at the time of such holder's death) for a period of 12 months from the date of death or until the expiration of the stated term of such award, whichever period is shorter.

If a participant's employment or service terminates by reason of retirement, any option held by such participant may be exercised (to the extent it was exercisable at

the time of retirement) for a period of five years from the date of such termination of employment or service or until the expiration of the stated term of such option, whichever period is the shorter. If the holder dies within such five-year period, however, any unexercised option held by such holder shall, notwithstanding the expiration of such five-year period, continue to be exercisable to the extent to which it was exercisable at the time of death for a period of 12 months from the date of such death or until the expiration of the stated term of such option, whichever period is the shorter.

If a participant's employment or service terminates for any reason other than death, disability, retirement, or cause, any option held by such participant or any permitted transferee of such participant may thereafter be exercised by the holder (to the extent it was exercisable at the time of termination) for a period of 90 days from the date of such termination of employment or service or until the expiration of the stated term of such option, whichever period is the shorter. If the holder dies within such 90 day period, however, any unexercised option so held shall continue to be exercisable to the extent to which it was exercisable at the time of death for a period of 12 months from the date of such death or until the expiration of the stated term of such option, whichever period is the shorter. If a participant's employment or service is terminated for cause, all rights under any option (whether vested or unvested) held by such participant shall expire immediately upon the giving to the participant of notice of such termination. No option may be exercised more than 10 years after the date of grant.

Payment of the option exercise price must be made within 10 business days after the option is exercised. The option award agreement shall specify the permissible means of payment, which may include cash, the surrender of shares of Stock held by the participant, the withholding by the Company of shares of Stock that otherwise would be delivered to the participant pursuant to the exercise of the option in an amount equaling in value the exercise price, a combination of either cash and delivery of shares, or cash and withholding of shares, or any other means the Committee may deem appropriate.

If an ISO is exercised after the expiration of the exercise periods that apply for the purposes of Section 422 of the Code, such option will be treated as a nonqualified option.

SARs. A SAR granted under the Plan represents the right of the participant to receive, upon settlement of the SAR, shares of Stock or cash equal to the amount by which the market value on the date of exercise of the SAR of the shares of Stock subject to the SAR exceeds the grant price of the SAR. The Committee may grant freestanding SARs, tandem SARs, or any combination thereof. The grant price of a freestanding SAR will equal the fair market value of the Stock on the date of grant. The grant price of a tandem SAR will equal the exercise price of the related option. A tandem SAR may be exercised for all or some of the shares subject to the related option upon the surrender of the right to exercise the equivalent portion of the

related option. A tandem SAR may be exercised only as to the shares for which its related option is then exercisable. The term of a SAR may not exceed 10 years, and the Committee may not grant dividend equivalent rights with respect to SARs.

Restricted Stock. The Committee may grant awards of restricted stock. Except as provided in the Plan, such awards may not be sold, transferred, pledged, assigned, or otherwise alienated until the end of a restriction period or upon earlier satisfaction of other conditions governing the award. In general, upon a participant's termination of employment during the period restrictions with respect to restricted stock are in effect, all such restricted stock held by the participant shall be forfeited. The holder of a restricted stock award has all of the rights of a stockholder of the Company, including the right to vote the shares, except that a participant's right to receive any dividends shall be subject to the same vesting period as the restricted stock to which such dividend rights relate, and shall be payable as soon as administratively practicable after the vesting thereof.

Stock Units. The Committee may grant awards of stock units. Such awards may be settled in cash or shares of Stock as determined by the Committee and the applicable Plan provisions. Payment with respect to stock units granted to a non-employee director shall be made upon the earliest of the date specified in the award agreement, the director's death, disability, retirement, resignation, or termination of service for reasons other than cause. In the event the director is terminated by the Company for cause, the Committee may determine that stock units held by such director shall be forfeited.

Performance Awards. The Committee may grant performance awards under the Plan, which entitle the participant to payment if the performance measures established by the Committee are met. If a participant terminates employment or service during a performance period applicable to a performance award because of death, disability, or retirement, the holder of the award shall be entitled to a payment with respect to each such outstanding performance award at the end of the applicable performance period based, to the extent relevant under the terms of the award, upon the participant's performance for the portion of such performance period ending on the date of termination and the performance of the Company or any applicable business unit for the entire performance period, and prorated for the portion of the performance period during which the participant was employed by, or provided services to, the Company. If a participant ceases employment or service during a performance period for any other reason, then such participant shall not be entitled to any payment with respect to any unvested performance award.

The Committee may pay earned performance units or performance shares in cash, shares of Stock, or a combination of cash and shares. Shares may be issued subject to any restrictions deemed appropriate by the Committee.

Section 162(m). If the Committee determines at the time of an award that is based on performance criteria is granted to a participant that the participant is likely

to be a "covered employee" within the meaning of Section 162(m) of the Code, the Committee may make the lapsing of the restrictions and the payment of the award subject to the achievement of one or more objective performance goals. Such performance goals shall be based on one or more of the following criteria, which, where applicable, shall be determined on a consolidated basis, and/or for specified subsidiaries, divisions, or other business units of the Company: earnings per share, revenues, cash flow, cash flow return on investment, return on net assets, return on assets, return on investment, return on invested capital, return on equity, profitability, economic value added ("EVA"), operating margins or profit margins, income or earnings before or after taxes, pretax earnings, pretax earnings before interest, depreciation and amortization, operating earnings, pretax operating earnings, before or after interest expense and before or after incentives, and extraordinary or special items, net income, total stockholder return or stock price, book value per share, expense management, improvements in capital structure, working capital, costs, and any of the above goals as compared to the performance of a published or special index deemed applicable by the Committee including, but not limited to, the Standard & Poor's 500 Stock Index or a group of comparator companies. EVA means the amount by which a business unit's earnings exceed the cost of the equity and debt capital used by the business unit during the performance period, as determined by the Committee. Income of a business unit may be before payment of bonuses, capital charges, non-recurring or extraordinary income or expense, and general and administrative expenses for the performance period, if so specified by the Committee. Such performance goals shall be set by the Committee within the time period prescribed by, and shall otherwise comply with the requirements of, Section 162(m) of the Code.

Transferability of Awards. Plan awards generally are not transferable other than by the laws of descent and distribution, and during his or her lifetime, only the participant may exercise an option or a SAR that has been granted to him or her. At the discretion of the Committee, however, awards (other than ISOs) may be transferred or assigned, without consideration, to a participant's spouse, children, stepchildren or grandchildren, or a family trust or family partnership.

Cancellation and Rescission of Awards. The Committee shall have the discretion with respect to any award granted under this Plan to establish upon its grant conditions under which the award may be later forfeited, cancelled, rescinded, suspended, withheld or otherwise limited or restricted, or gains realized by the grantee in connection with an award or an award's exercise may be recovered. These conditions may include, without limitation, actions by the participant which constitute a conflict of interest with the Company, violate the Company's code of business conduct, are prejudicial to the Company's interests, or are in violation of any non-compete agreement or obligation, any confidentiality agreement or obligation, the Company's applicable policies or the participant's terms and conditions of employment.

Amendment and Termination. The Board of Directors may amend or terminate the Plan at any time. Stockholder approval is required for any amendment increasing the number of shares available for Plan awards, lowering the exercise price of any outstanding option or SAR, or authorizing the grant of new awards in exchange for the surrender of outstanding awards.

The Committee may make adjustments in the terms and conditions of, and the criteria included in, awards in recognition of unusual or nonrecurring events affecting the Company or of changes in applicable laws, regulations or accounting principles, if the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

Change in Control. In the event of a change in control, as defined in the Plan, any time periods, conditions or contingencies relating to the exercise or realization of, or lapse of restrictions under, any outstanding award under the Plan shall be automatically accelerated or waived so that if no exercise of the award is required, the award may be realized in full at the time of the occurrence of the change in control, and if exercise of the award is required the award may be exercised at the occurrence of the change in control.

Effective Date. The Plan is effective on April 27, 2006, subject to approval of the stockholders of the Company at the 2006 annual meeting of stockholders, and unless the Plan is terminated sooner by the Board of Directors, no further awards may be granted under the Plan on or after April 26, 2016.

Federal Income Tax Consequences of Awards Granted under the Plan

The following is a general description of the United States federal income tax consequences to participants and the Company relating to SARs, options, restricted stock units and other awards that may be granted under the Plan. The plan is not qualified under Section 401(a) of the Code. This discussion only applies to U.S. citizens and/or residents and does not purport to cover all tax consequences relating to SARs, options, stock units and other awards.

Stock Appreciation Rights (SARs). A participant will generally not recognize income, and the Company will not be entitled to a deduction from income, at the time of grant of a SAR. When the SAR is exercised, the participant will recognize ordinary income equal to the difference between the aggregate grant price and the fair market value, as of the date the SAR is exercised, of the Stock. The participant's tax basis in shares acquired upon exercise of a stock-settled SAR will equal the amount recognized by the participant as ordinary income. The Company will generally be entitled to a federal income tax deduction, in the tax year in which the SAR is exercised, equal to the ordinary income recognized by the participant as described above. If the participant holds shares acquired through exercise of a stock-settled SAR for more than one year after the exercise of the SAR, the capital gain or loss realized

upon the sale of those shares will be a long-term capital gain or loss. The participant's holding period for shares acquired upon the exercise of a stock-settled SAR will begin on the date of exercise.

Nonqualified Stock Options. A participant will generally not recognize income, and the Company will not be entitled to a deduction from income, at the time of grant of a nonqualified stock option. When shares of Stock are delivered to the participant upon exercise of the option, the participant will recognize ordinary income equal to the difference, if any, between the fair market value of the shares at that time and the aggregate exercise price. The participant's tax basis in shares acquired upon exercise will equal the exercise price paid plus the amount recognized by the participant as ordinary income. The Company will generally be entitled to a federal income tax deduction, in the tax year in which the option is exercised, equal to the ordinary income recognized by the participant as described above. If the participant holds shares acquired through exercise of a nonqualified stock option for more than one year after the exercise of the option, the capital gain or loss realized upon the sale of those shares will be a long-term capital gain or loss. The participant's holding period for shares acquired upon the exercise of an option will begin on the date of exercise.

ISOs. A participant will generally not recognize income, and the Company will not be entitled to a deduction from income, at the time of grant of an ISO. If the option is exercised during employment, or within three months thereafter (or one year in the case of a permanently and totally disabled employee), the participant will generally not recognize any income and the Company will not be entitled to a deduction. However, the excess of the fair market value of the shares on the date shares of Stock are transferred to the participant over the exercise price generally is included in computing the participant's alternative minimum taxable income.

Generally, if the participant disposes of shares acquired by exercise of an ISO within either two years after the date of grant or one year after the date of exercise, the participant will recognize ordinary income, and the Company will be entitled to a deduction, equal to the excess of the fair market value of the shares on the date the shares were transferred to the participant over the option price (limited generally to the gain on the sale). The balance of any gain or loss will be treated as a capital gain or loss to the participant. If shares are disposed of after the two year and one year periods described above expire, the Company will not be entitled to any deduction, and the participant's entire gain or loss will be a long-term capital gain or loss.

Stock Units. Stock units generally are subject to tax at the time of payment and the Company generally will have a corresponding deduction when the participant recognizes income.

Other Awards. The current federal income tax consequences of other awards authorized under the Plan are generally in accordance with the following:

•: restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value of shares over the purchase price (if any) only at the time the restrictions lapse (unless the participant properly elects to accelerate recognition as of the date of grant); and
•: performance shares and dividend equivalents generally are subject to tax at the time of payment.

In each of the foregoing cases, the Company will generally have a corresponding deduction at the time the participant recognizes income.

Compliance with Section 409A of the Internal Revenue Code. The American Jobs Creation Act of 2004 enacted Section 409A of the Code, which is applicable to certain types of awards that may be granted under the Plan. To the extent applicable, it is intended that the Plan and any grants made under the Plan comply with the provisions of Section 409A. The Company intends to administer the Plan and any grants made thereunder in a manner consistent with the requirements of Section 409A, and to adopt such amendments (including retroactive amendments) to the Plan and any grants made thereunder as may be required in order to comply with Section 409A.

APPROVAL OF SELECTION
OF INDEPENDENT AUDITOR

The Board of Directors has, subject to approval by the stockholders, selected the firm of KPMG LLP to act as auditor for the fiscal year 2006. The Board of Directors recommends a vote FOR approval, and unless otherwise directed, proxies will be voted in favor of this selection. The affirmative vote of the holders of a majority of the shares of the Company represented and entitled to vote at the meeting is required for such approval.

Representatives of KPMG LLP will be present at the annual meeting, with the opportunity to make a statement if they desire to do so and to respond to appropriate questions raised at the meeting.

SECTION 16(a) BENEFICIAL OWNERSHIP
REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires the Company's officers and directors, and stockholders who own more than ten percent of a registered class of the

Company's equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission and the New York Stock Exchange. Officers, directors and stockholders who own more than ten percent of such of the Company's securities are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

Based solely on its review of the copies of such forms received by it, or written representations from certain reporting persons that no Forms 5 were required for those persons, the Company believes that during fiscal year 2005, all filings required of its officers, directors and covered stockholders were made in compliance with applicable SEC regulations, with the sole exception of a Form 4 filing by Mr. Wood that was inadvertently filed late pertaining to ownership of Company common stock reported as indirectly instead of directly owned.

COMMUNICATIONS WITH THE BOARD
OF DIRECTORS

Stockholders, employees and other interested parties may communicate with the Company's Board of Directors, independent co-lead directors or any member of the Board, in the following manner:

By telephone at any time, confidentially or anonymously, toll free, by calling 1-800-729-1514 from inside the United States or Canada, or outside the area by calling 1-704-501-2359 (collect).

By writing, confidentially or anonymously, to the Chemtura Corporation Board of Directors, c/o CCI, P.O. Box 461915, Charlotte, NC 28256.

It is the Company's policy that directors attend all meetings of the Board of Directors and the Company's annual meeting. All directors attended the 2005 annual meeting of stockholders.

MAILINGS TO STOCKHOLDERS

The Company has adopted a procedure approved by the Securities and Exchange Commission called "householding." Under this procedure, a single set of annual reports and proxy statements may be sent to a single address if two or more stockholders share that address, unless the Company has received a request from one

or more of such stockholders to the contrary. This procedure reduces the Company's mailing and printing expenses.

Upon request, the Company will promptly send a separate Annual Report for 2005 or this Proxy Statement to any stockholder residing at such a shared address. Requests may be made by calling Investor Relations at (203) 573-2163 or by writing to Investor Relations, Chemtura Corporation, 199 Benson Road, Middlebury, CT 06749 USA. If any registered stockholder residing at a shared address wishes to receive a separate annual report or proxy statement in the future, or if any registered stockholder receiving multiple copies of the Company's annual report and proxy statement desires householding, the stockholder may contact Investor Relations at Chemtura Corporation in the manner described above. Stockholders owning shares through a bank, broker or other nominee should contact the nominee concerning householding procedures.

AVAILABLE INFORMATION

The Company's internet website address is www.chemtura.com. The Company's Corporate Governance Principles, Code of Business Conduct and charters for its Audit Committee and its Organization, Compensation and Governance Committee are available on the Company's website and will be available, free of charge, to any stockholder who requests them from the Corporate Secretary at Chemtura Corporation, 199 Benson Road, Middlebury, CT 06749 USA.

OTHER MATTERS

As of the date of this statement, the Board of Directors does not know of any matter other than those referred to in this Proxy Statement as to which action is expected to be taken at the annual meeting of stockholders.

The shares represented by proxies in the form solicited by the Board of Directors will be voted at the meeting. Where a choice is specified on the proxy with respect to a matter to be voted upon, the shares represented by the proxy will be voted in accordance with the specification so made. If no choice is specified, such shares will be voted (i) for the election as directors of the four nominees for directorships named herein; (ii) in favor of a proposal to amend the Company's Amended and Restated Certificate of Incorporation to declassify the Board; (iii) in favor of approving the 2006 Chemtura Corporation Long-Term Incentive Plan; and (iv) in favor of the selection of KPMG LLP as the Company's independent auditor for fiscal year 2006.

D-5

indemnified and protected by the Company with respect to any such action, determination, or interpretation.

Section 5: Awards.

Such awards may be in a form payable in either Stock or cash, including, but not limited to, Stock Option Awards, Stock, Restricted Stock, bonus Stock, SARs, Stock Units, Performance Awards and dividend equivalents. The Committee is authorized to grant awards as a bonus, or to grant awards in lieu of obligations of the Company to pay cash or grant other awards under other plans or compensatory arrangements, to the extent permitted by such other plans or arrangements. All awards shall be made pursuant to award agreements between the Participant and the Company or such other plans as the Committee may adopt from time to time. The agreements or plans shall be in such form as the Committee approves from time to time.

5.2: Terms and Conditions of Awards. The Committee shall determine the size of each award to be granted (including, where applicable, the number of shares of Stock to which an award will relate), and all other terms and conditions of each such award (including, but not limited to, any exercise price, grant price, or purchase price, any restrictions or conditions relating to transferability, forfeiture, exercisability, or settlement of an award, and any schedule or performance conditions for the lapse of such restrictions or conditions, and accelerations or modifications thereof, based in each case on such considerations as the Committee shall determine). The Committee may determine whether, to what extent, and under what circumstances an award may be settled, or the exercise price of an award may be paid, in cash, shares of Stock, other awards, or other consideration, or an award may be canceled, forfeited, or surrendered. The right of a Participant to exercise or receive a grant or settlement of any award, and the timing thereof, may be subject to such performance conditions as may be specified by the Committee. The Committee may use such business criteria and measures of performance as it may deem appropriate in establishing performance conditions, and may exercise its discretion to reduce or increase the amounts payable under any award subject to performance conditions, except as limited under Section 13.1 in the case of a Qualified Performance-Based Award intended to qualify under Code Section 162(m). Notwithstanding the foregoing, (i) the period during which an award may remain outstanding shall not exceed ten (10) years from the date the award is granted, (ii) no Full-Value Award issued under the Plan (other than Full-Value Awards that are either performance-based or granted to Non-Employee Directors) shall fully vest within one (1) year from the date of grant of such Full-Value Award, and (iii) any awards granted to Non-Employee Directors shall be granted to all Non-Employee Directors on a non-discretionary basis based on a formula approved by the Committee.

D-6

5.3: Maximum Amount Available. The total number of shares of Stock that may be delivered to Participants or their beneficiaries pursuant to all awards granted under this Plan shall not exceed 10,500,000 shares. Solely for the purpose of computing the foregoing maximum shares of Stock limitation under this Plan, there shall not be counted: (i) any shares which have been forfeited or lapse under the Plan and (ii) any shares deliverable pursuant to an award which, prior to such computation, has terminated in accordance with its terms or has been cancelled by the Participant or the Company. In addition, for the purpose of computing the foregoing maximum shares of Stock limitation under this Plan, to the extent SAR awards are granted, the total number of shares of Stock subject to the SAR upon grant shall be counted.

5.4: Award Specific Limitations. The total number of shares of Stock available for delivery under the Plan pursuant to awards of Incentive Stock Options shall not exceed the total number of shares defined above in Section 5.3 The combined number of shares of Stock granted under this Plan pursuant to Full-Value Awards shall not exceed 33% of the maximum number of shares of Stock available for award under the Plan as provided in Sections 5.3 and 5.6.

5.5: Per Participant Limitation on Stock-Based Awards. In any calendar year, no Participant may be granted awards that relate to more than 25% of the shares of Stock reserved. In addition, no more than 300,000 shares of Stock pursuant to any Performance Awards shall be granted to one individual in a calendar year unless pursuant to a multi-year award. This Section 5.5 shall apply only with respect to awards that are denominated by a specified number of shares of Stock, even if the award may be settled in cash or a form other than Stock. If the number of shares of Stock ultimately payable in respect of an award is a function of future achievement of performance targets, then for purposes of this limitation, the number of shares of Stock to which such award relates shall equal the number of shares of Stock that would be payable assuming maximum performance was achieved.

5.6: Adjustment in the Event of Recapitalization, etc. In the event of any change in the outstanding shares of Chemtura by reason of any stock split, stock dividend, recapitalization, merger, consolidation, combination or exchange of shares or other similar corporate change or in the event of any special distribution to the stockholders, the Committee shall make such equitable adjustments in the number of shares and prices per share applicable to options then outstanding and in the number of shares which are available thereafter for other awards, both under the Plan as a whole and with respect to individuals and award type, as the Committee determines are necessary and appropriate. In addition, the Committee is authorized to make adjustments in the terms and conditions of, and the criteria included in, awards (including cancellation of awards in exchange for the intrinsic (i.e., in-the-money) value, if any, of the vested portion thereof, substitution of awards using securities or other obligations of a successor or other entity, acceleration of the expiration date for awards, or adjustment to performance goals in respect of awards) in recognition of unusual or nonrecurring events (including events described in the preceding sentence,

D-7

as well as acquisitions and dispositions of businesses and assets) affecting the Company, the financial statements of the Company, or in response to changes in applicable laws, regulations, or accounting principles. Notwithstanding the foregoing, if any such event will result in the acquisition of all or substantially all of the Company's outstanding Stock, then if the document governing such acquisition (e.g., merger agreement) specifies the treatment of outstanding awards, such treatment shall govern without the need for any action by the Committee. Any such adjustment shall be conclusive and binding for all purposes of the Plan.

5.7: Stand-Alone, Additional, Tandem, and Substitute Awards. Subject to Section 6.3, awards granted under the Plan may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution or exchange for, any other award or any award granted under another plan of the Company or any business entity to be acquired by the Company, or any other right of a Participant to receive payment from the Company, and in granting a new award, the Committee may determine that the value of any surrendered award or award may be applied to reduce the exercise price of any Stock Option Award or SAR or purchase price of any other award.

Section 6: Stock Options.

6.1: Award Types. The Company may award options to purchase Stock (hereinafter referred to as "Stock Option Awards") to such Participants as the Committee authorizes and under such terms as the Committee establishes. The Committee shall determine with respect to each Stock Option Award, and designate in the grant, whether a Participant is to receive an Incentive Stock Option or a Non-Qualified Stock Option, or combination thereof. Notwithstanding the foregoing, Incentive Stock Options may be granted only to Eligible Employees.

6.2: Exercise Price. The exercise price of each share of Stock subject to a Stock Option Award shall be specified in the grant, but in no event shall the exercise price be less than the Market Value of the Stock on the date the award is granted. If the Participant to whom an Incentive Stock Option is granted owns, at the time of the grant, more than ten percent (10%) of the combined voting power of the Participant's employer or a parent or subsidiary of the employer, the exercise price of each share of Stock subject to such grant shall be not less than one hundred ten percent (110%) of the price described in the preceding sentence.

6.3: Repricing. The exercise price of any Stock Option Award granted pursuant to this Plan shall not be changed following the date of its grant, other than such equitable changes as may arise in connection with the adjustments permitted under Section 5.6 and no Stock Option Award may be cancelled and replaced with a new Stock Option Award with a lower exercise price where the economic effect would be the same as reducing the exercise price of the cancelled option.

D-8

6.4: Duration of Stock Option Awards. A Stock Option Award by its terms shall be of no more than ten (10) years' duration, except that an Incentive Stock Option granted to a Participant who, at the time of the grant, owns Stock representing more than ten percent (10%) of the combined voting power of the Participant's employer or a parent or subsidiary of the employer shall by its terms be of no more than five (5) years' duration.

6.5 Exercisability. Stock Option Awards shall be exercisable at such time as the Committee shall determine and specify in the grant (but not less than one year following the date of grant of such award) provided, however, that, Stock Option Awards shall also be exercisable as follows:

(a) if a Participant's employment or service terminates by reason of death, any Stock Option Award held by such Participant or any permitted transferee of such Participant may thereafter be exercised, to the extent then exercisable, for a period of two years from the date of such death or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter;

(b) if a Participant's employment or service terminates by reason of Disability, any Stock Option Award held by such Participant or any permitted transferee of such Participant may thereafter be exercised, to the extent it was exercisable at the time of termination, for a period of two years from the date of such termination of employment or service or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter; provided, however, that, if the holder of the Stock Option Award dies while any such Stock Option Award remains exercisable, any unexercised Stock Option Award so held at death shall continue to be exercisable to the extent to which it was exercisable at the time of such holder's death for a period of 12 months from the date of such death or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter. In the event of termination of employment by reason of Disability, if an Incentive Stock Option is exercised after the expiration of the exercise periods that apply for purposes of Section 422 of the Code, such Stock Option Award will thereafter be treated as a Non-Qualified Stock Option;

(c) If a Participant's employment or service terminates by reason of Retirement, any Stock Option Award held by such Participant or any permitted transferee of such Participant may thereafter be exercised by the holder, to the extent it was exercisable at the time of Retirement, for a period of five years from the date of such termination of employment or service or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter; provided, however, that if the holder dies within such five-year period, any unexercised Stock Option Award held by such holder shall, notwithstanding the expiration of such five-year period, continue to be exercisable to the extent to which it was exercisable at the time of death for a period of 12 months from the date of such death or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter. In the event of termination of employment by reason of Retirement, if an Incentive

D-9

Stock Option is exercised after the expiration of the exercise periods that apply for the purposes of Section 422 of the Code, such Stock Option Award will thereafter be treated as a Non-Qualified Stock Option;

(d) if a Participant's employment or service terminates for any reason other than death, Disability, Retirement, or Cause, any Stock Option Awards held by such Participant or any permitted transferee of such Participant may thereafter be exercised by the holder, to the extent it was exercisable at the time of termination, for a period of 90 days from the date of such termination of employment or service or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter; provided, however, that if the holder dies within such 90 day period, any unexercised Stock Option Award so held shall, notwithstanding the expiration of such 90 day period, continue to be exercisable to the extent to which it was exercisable at the time of death for a period of 12 months from the date of such death or until the expiration of the stated term of such Stock Option Award, whichever period is the shorter. If a Participant's employment or service is terminated for Cause, all rights under any Stock Option Award (whether vested or unvested) held by such Participant or any permitted transferee of such Participant shall expire immediately upon the giving to the Participant of notice of such termination.

Notwithstanding anything the foregoing, in no event may a Stock Option Award be exercised after its expiration date.

6.6: Manner of Exercise. A Stock Option Award may be exercised by the Participant (or, if the Stock Option Award has been duly transferred, the transferee) with respect to part or all of the shares subject to the option by giving written notice to the Company or its designee of the exercise of the option according to such procedures as the Executive Vice President, Human Resources may establish.

6.7: Payment of Exercise Price. The exercise price for the shares for which an option is exercised shall be paid by the exercisor within ten (10) business days after the date of exercise and the terms of the Stock Option Award may provide that the exercise price may be paid:

(a) in cash;

(b) in whole shares of Stock owned by the exercisor prior to exercising the option;

(c) by having the Company withhold shares that otherwise would be delivered to the exercisor pursuant to the exercise of the option in an amount equaling in value the exercise price;

(d) in a combination of either cash and delivery of shares, or cash and withholding of shares; or

(e) by whatever other means the Committee may deem appropriate.

The Company shall establish procedures in connection with payments pursuant to (b), (c), (d), and (e) above, to ensure that the Plan does not become subject to

D-10

variable accounting by virtue of such payment methods. The value of any share of Common Stock delivered or withheld in payment of the exercise price shall be its Market Price on the date the option is exercised.

6.8: Limits on Incentive Stock Options. The aggregate Market Value of all shares of Stock with respect to which Incentive Stock Options are exercisable for the first time by a Participant in any one calendar year, under this Plan or any other stock option plan maintained by the Company, shall not exceed $100,000. The Market Value shall be determined on the date the related Stock Option Award is granted.

Section 7: Grants of Stock.

7.1: Award Types. The Committee may grant, either alone or in addition to other awards granted under the Plan, shares of Stock or Restricted Stock (hereinafter referred to as a "Stock Award") to such Participants as the Committee authorizes and under such terms as the Committee establishes. The Committee, in its discretion, may also make a cash payment to a Participant granted shares of Stock or Restricted Stock under the Plan to allow such Participant to satisfy tax obligations arising out of receipt of the Stock or Restricted Stock.

7.2: Vesting Periods. A grant of Restricted Stock pursuant to this Section 7 shall be subject to a minimum vesting period of at least three (3) years, or such longer period as the Committee, in its sole discretion, may determine, provided, however, that grants of Restricted Stock to new Eligible Employees that are made as a replacement for restricted stock grants of a prior employer may be subject to a shorter vesting period as the Committee, in its sole discretion, may determine. Notwithstanding the foregoing, the Committee may grant shares of Restricted Stock with a vesting period of at least two (2) years, or such longer period as the Committee, in its sole discretion, may determine, so long as vesting is based on performance criteria.

7.3: Rights as a Stockholder. The Participant shall have, with respect to Restricted Stock, all of the rights of a stockholder of the Corporation, including the right to vote the shares, except that a Participant's right to receive any dividends shall be subject to the same vesting period as the Restricted Stock to which such dividend rights relate, and shall be payable as soon as administratively practicable after the vesting thereof (but in any event by March 15 following the year in which vesting occurs).

7.4: Transferability. Restricted Stock may not be sold or transferred by the Participant until any restrictions that have been established by the Committee have lapsed.

7.5: Forfeiture. Upon a termination by the Participant or the Company of the Participant's employment or service for any reason during the period any restrictions are in effect, all Restricted Stock held by the Participant shall be forfeited without compensation to the Participant.

D-11

Section 8: SARs.

8.1: General Requirements. The Committee may grant awards of Stock appreciation rights ("SARs") to any Participant, upon such terms and conditions as the Committee deems appropriate under this Section 8. Each SAR shall represent the right of the Participant to receive, upon settlement of the SAR, shares of Stock or cash equal to the amount by which the Market Value of a share of Stock on the date of exercise of the SAR exceeds the base amount of the SAR as described below in Section 8.3.

8.2: Terms of SARs. The Committee shall determine the terms and conditions of SARs and may grant SARs separately from or in tandem with any Stock Option Award (for all or a portion of the applicable Stock Option Award). Tandem SARs may be granted either at the time the Stock Option Award is granted or any time thereafter while the Stock Option Award remains outstanding; provided, however, that in the case of an Incentive Stock Option, SARs may be granted only at the time of the grant of the Incentive Stock Option. The Committee will determine the number of SARs to be granted, the base amount, the vesting and other restrictions applicable to SARs and the period during which SARs will remain exercisable. A Stock appreciation right award by its term shall be of no more than ten (10) years' duration.

8.3: Base Amount. The Committee shall establish the base amount of the SAR at the time the SAR is granted; provided, however, that the base amount shall not be less than the Market Value of a share of Stock on the date of grant.

8.4: Payment With Respect to SARs. The Committee shall determine whether the appreciation in a SAR shall be paid in the form of cash, in Stock, or in a combination of the two, in such proportion as the Committee deems appropriate. For purposes of calculating the number of shares of Stock to be received, Stock shall be valued at its Market Value on the date of exercise of the SAR. If shares of Stock are to be received upon exercise of a SAR, cash shall be delivered in lieu of any fractional share.

8.5: Requirement of Employment or Service. The Committee shall determine in the award agreement under what circumstances a Participant may retain SARs after termination of the Participant's employment or service, and the circumstances under which SARs may be forfeited.

Section 9: Stock Units.

9.1: General Requirements. The Committee may grant Stock Units to any Participant, upon such terms and conditions as the Committee deems appropriate under this Section 9. Each Stock Unit shall represent the right of the Participant to receive a share of Stock or an amount based on the value of a share of Stock. All Stock Units shall be credited to accounts on the Company's records for purposes of the Plan.

D-12

9.2: Terms of Stock Units. The Committee may grant Stock Units that are payable if specified performance goals or other conditions are met, or under other circumstances. Stock Units may be paid at the end of a specified period, or payment may be deferred to a date authorized by the Committee. The Committee shall determine the number of Stock Units to be granted and the requirements applicable to such Stock Units.

9.3: Payment With Respect to Stock Units. Payment with respect to Stock Units shall be made in cash, in Stock, or in a combination of the two, as determined by the Committee, and at such times as specified in the award agreement in accordance with section 409A of the Code. The award agreement shall specify the maximum number of shares that shall be paid under the Stock Units.

Payment with respect to Stock Units granted to a Non-Employee Director shall be made upon the earliest of:

(i) such date as the Committee shall determine and specify in the grant;

(ii) such Non-Employee Director's death, Disability, or retirement; or

(iii) resignation by the Non-Employee Director or the termination of such Non-Employee Director's service for reasons other than Cause.

In the event the Non-Employee Director is terminated by the Company for Cause, the Committee may determine that Stock Units held by such Non-Employee Director shall be forfeited.

9.4: Requirement of Employment or Service. The Committee shall determine in the award agreement under what circumstances a Participant may retain Stock Units after termination of the Participant's employment or service, and the circumstances under which Stock Units may be forfeited.

Section 10: Dividend Equivalents.

When the Committee makes a grant of a Full-Value Award under the Plan, the Committee may grant Dividend Equivalents in connection with such awards, under such terms and conditions as the Committee deems appropriate under this Section 10. In no event will the Committee grant Dividend Equivalents other than in connection with a Full-Value Award. Dividend Equivalents may be paid to Participants currently or may be deferred, as determined by the Committee. All Dividend Equivalents that are not paid currently shall be credited to accounts on the Company's records for purposes of the Plan. Unless otherwise specified in the award agreement, Dividend Equivalents shall be subject to the same vesting period as the award to which they relate and shall be payable as soon as administratively practicable after the vesting thereof (but in any event by March 15 following the year in which vesting occurs). Dividend Equivalents may be accrued as a cash obligation, or may be converted to Stock Units for the Participant, as determined by the Committee. Unless otherwise specified in the award agreement, deferred Dividend Equivalents will not accrue

D-13

interest. The Committee may provide that Dividend Equivalents shall be payable based on the achievement of specific performance goals.

Section 11: Performance Awards.

11.1: Award Types. The Committee may grant, either alone or in addition to other awards granted under the Plan, awards of Stock and other awards that are valued in whole or in part by reference to, or are otherwise based on, the Market Value of Stock, or other securities of the Company, based on the performance of the Company ("Performance Awards") to such Participants as the Committee authorizes and under such terms as the Committee establishes. Performance Awards may be paid in Stock, Restricted Stock or other securities of the Company, cash or any other form of property as the Committee shall determine.

11.2: Terms and Conditions of Awards. Performance Awards shall entitle the Participant to receive an award if the measures of performance established by the Committee are met. The measures of performance shall be established by the Committee in its absolute discretion. The Committee shall determine the times at which Performance Awards are to be made and all conditions of such awards. Notwithstanding the foregoing, if a Participant terminates employment or service during a performance period applicable to a Performance Award because of death, Disability, or Retirement, such Participant shall be entitled to a payment with respect to each such outstanding Performance Award at the end of the applicable performance period:

(i) based, to the extent relevant under the terms of the award, upon the Participant's performance for the portion of such performance period ending on the date of termination and the performance of the Company or any applicable business unit for the entire performance period, and

(ii) prorated for the portion of the performance period during which the Participant was employed by, or provided services to, the Company, all as determined by the Committee.

If a Participant ceases employment or service during a performance period for any other reason, then such Participant shall not be entitled to any payment with respect to any unvested Performance Award.

Section 12: Other Awards.

The Committee may grant other awards that are cash-based or based on, measured by or payable in Stock to Participants, on such terms and conditions as the Committee deems appropriate under this Section 12. Other Awards may be granted subject to achievement of performance goals or other conditions and may be payable in Stock or cash, or in a combination of the two, as determined by the Committee in the award agreement or applicable plan.

D-14

Section 13: Qualified Performance-Based Awards.

13.1: Performance Awards Granted to Designated Covered Employees. If the Committee determines that an award to be granted to a Participant who is designated by the Committee as likely to be a Covered Employee (as defined below) should qualify as "performance-based compensation" for purposes of Code Section 162(m), the grant, exercise, and/or settlement of such award (a "Qualified Performance-Based Award") shall be contingent upon achievement of preestablished performance goals and other terms set forth in this Section 13. This Section 13 shall not apply to awards that otherwise qualify as "performance-based compensation" by reason of Regulation §1.162-27(e)(2)(vi) (relating to certain stock options and stock appreciation rights).

(a) Performance Goals Generally. The performance goals for such Qualified Performance-Based Awards shall consist of one or more business criteria and a targeted level or levels of performance with respect to each such criteria, as specified by the Committee consistent with this Section 13.1. Performance goals shall be objective and shall otherwise meet the requirements of Code Section 162(m) and regulations thereunder (including Regulation §1.162-27 and successor regulations thereto), including the requirement that the level or levels of performance targeted by the Committee result in the achievement of performance goals being "substantially uncertain." The Committee may determine that such Qualified Performance-Based Awards shall be granted, exercised, and/or settled upon achievement of any one performance goal or that two or more of the performance goals must be achieved as a condition to grant, exercise, and/or settlement of such Qualified Performance-Based Awards. Performance goals may differ for Qualified Performance-Based Awards granted to any one Participant or to different Participants.

(b) Business Criteria. One or more of the following business criteria for the Company, on a consolidated basis, and/or for specified Subsidiaries, divisions, or other business units of the Company (where the criteria are applicable), shall be used by the Committee in establishing performance goals for such Qualified Performance-Based Awards: (1) earnings per share; (2) revenues; (3) cash flow; (4) cash flow return on investment; (5) return on net assets, return on assets, return on investment, return on invested capital, return on equity; profitability; (6) economic value added ("EVA"); (7) operating margins or profit margins; (8) income or earnings before or after taxes; pretax earnings; pretax earnings before interest, depreciation and amortization; operating earnings; pretax operating earnings, before or after interest expense and before or after incentives, and extraordinary or special items; net income; (9) total stockholder return or stock price; (10) book value per share; (11) expense management; improvements in capital structure; working capital; costs; and (12) any of the above goals as compared to the performance of a published or special index deemed applicable by the Committee including, but not limited to, the Standard & Poor's 500 Stock Index or a group of comparator companies. EVA means the amount by which a business unit's earnings exceed the cost of the equity and debt capital used by the business unit during the performance period, as determined by the Committee.

D-15

Income of a business unit may be before payment of bonuses, capital charges, non-recurring or extraordinary income or expense, and general and administrative expenses for the performance period, if so specified by the Committee.

(c) Performance Period; Timing for Establishing Qualified Performance-Based Award Terms. Achievement of performance goals in respect of such Qualified Performance-Based Awards shall be measured over a performance period of up to ten years, as specified by the Committee. Performance goals, amounts payable upon achievement of such goals, and other material terms of Qualified Performance-Based Awards shall be established by the Committee (i) while the performance outcome for that performance period is substantially uncertain and (ii) no more than 90 days after the commencement of the performance period to which the performance goal relates or, if less, the number of days which is equal to 25 percent of the relevant performance period.

(d) Qualified Performance-Based Award Pool. The Committee may establish a Qualified Performance-Based Award pool, which shall be an unfunded pool, for purposes of measuring performance of the Company in connection with Qualified Performance-Based Awards. The amount of such Qualified Performance-Based Award pool shall be based upon the achievement of a performance goal or goals based on one or more of the business criteria set forth in Section 13.1(b) hereof during the given performance period, as specified by the Committee in accordance with Section 13.1(c) hereof. The Committee may specify the amount of the Qualified Performance-Based Award pool as a percentage of any of such business criteria, a percentage thereof in excess of a threshold amount, or as another amount which need not bear a strictly mathematical relationship to such business criteria. In such case, Qualified Performance-Based Awards may be granted as rights to payment of a specified portion of the Qualified Performance-Based Award pool, and such grants shall be subject to the requirements of Section 13.1(c).

(e) Settlement of Qualified Performance-Based Awards; Other Terms. Settlement of such Qualified Performance-Based Awards shall be in cash, Stock, other awards, in the discretion of the Committee. The Committee may, in its discretion, reduce the amount of a settlement otherwise to be made in connection with such Qualified Performance-Based Awards, but may not exercise discretion to increase any such amount payable to a Covered Employee in respect of a Qualified Performance-Based Award subject to this Section 13.1. The Committee shall specify the circumstances in which such Qualified Performance-Based Awards shall be paid or forfeited in the event of termination of employment by the Participant prior to the end of a performance period or settlement of Qualified Performance-Based Awards.

(f) Impact Of Extraordinary Items Or Changes In Accounting. To the extent applicable, the determination of achievement of performance goals for Qualified Performance-Based Awards shall be made in accordance with U.S. generally accepted accounting principles ("GAAP") and a manner consistent with the methods used in the Company's audited financial statements, and, unless the Committee decides

D-16

otherwise within the period described in Section 13.1(c), without regard to (i) extraordinary items as determined by the Company's independent public accountants in accordance with GAAP, (ii) changes in accounting methods, or (iii) non-recurring acquisition expenses and restructuring charges. Notwithstanding the foregoing, in calculating operating earnings or operating income (including on a per share basis), the Committee may, within the period described in Section 13.1(c), provide that such calculation shall be made on the same basis as reflected in a release of the Company's earnings for a previously completed period as specified by the Committee.

13.2: Written Determinations. Determinations by the Committee as to the establishment of performance goals, the amount potentially payable in respect of Qualified Performance-Based Awards, the achievement of performance goals relating to Qualified Performance-Based Awards, and the amount of any final Qualified Performance-Based Award shall be recorded in writing. Specifically, the Committee shall certify in writing, in a manner conforming to applicable regulations under Code Section 162(m), prior to settlement of each Qualified Performance-Based Award, that the performance goals and other material terms of the Qualified Performance-Based Award upon which settlement of the Qualified Performance-Based Award was conditioned have been satisfied. The Committee may not delegate any responsibility relating to such Qualified Performance-Based Awards, and the Board shall not perform such functions at any time that the Committee is composed solely of Qualified Members.

13.3: Status of Section 13.1 Awards under Code Section 162(m). It is the intent of the Company that Qualified Performance-Based Awards under Section 13.1 constitute "performance-based compensation" within the meaning of Code Section 162(m) and regulations thereunder. Accordingly, the terms of Sections 13.1, 13.2 and 13.3, including the definitions of Covered Employee and other terms used therein, shall be interpreted in a manner consistent with Code Section 162(m) and regulations thereunder. The foregoing notwithstanding, because the Committee cannot determine with certainty whether a given Participant will be a Covered Employee with respect to a fiscal year that has not yet been completed, the term "Covered Employee" as used herein shall mean only a person designated by the Committee, at the time of grant of a Qualified Performance-Based Award, as likely to be a Covered Employee with respect to a specified fiscal year. If any provision of the Plan as in effect on the date of adoption of any agreements relating to Qualified Performance-Based Awards does not comply or is inconsistent with the requirements of Code Section 162(m) or regulations thereunder, such provision shall be construed or deemed amended to the extent necessary to conform to such requirements.

Section 14: Vesting on Change in Control.

Notwithstanding anything in the Plan to the contrary, in the event of a Change in Control any time periods, conditions or contingencies relating to the exercise or

D-17

realization of, or lapse of restrictions under, any outstanding award under the Plan shall be automatically accelerated or waived so that if no exercise of the award is required, the award may be realized in full at the time of the occurrence of the Change in Control or if exercise of the award is required, the award may be exercised at the occurrence of the Change in Control.

Section 15: General Provisions.

15.1: Assignment. Subject to the provisions of Section 15.2, if applicable, any assignment or transfer of any awards without the written consent of the Company shall be null and void.

15.2: Transferability.

(a) Generally, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber shares of Stock received pursuant to the Plan prior to the date on which any applicable restriction or performance period established by the Committee lapses. Notwithstanding the foregoing, awards shall be transferable by the Participant:

(i) in the case of the Participant's death (to the extent the award, by its terms, survives the Participant's death), pursuant to the beneficiary designation then on file with the Company, or, in the absence of such a beneficiary designation (or if the designated beneficiary has pre-deceased the Participant), by will or the laws of descent and distribution (in which case the Company without liability to any other person, may rely on the directions of the executor or administrator of the Participant's estate with respect to the disposition or exercise of such awards);

(ii) in the Committee's discretion, the terms of an award (other than an Incentive Stock Option) may permit the Participant to transfer the award to (w) his or her spouse, children (including by adoption), stepchildren or grandchildren (referred to herein as the Participant's "Family Members"), (x) a trust or trusts for the exclusive benefit of such Family Members, (y) a partnership in which such Family Members are the only partners, or (z) such other persons or entities as the Committee may approve on a case-by-case basis; or

(iii) In the case of a transferee's death, to his/her estate without rights to further distribution.

(b) Any transfer pursuant to this Section 15.2 shall be subject to the following:

(i) there may be no consideration for any such transfer;

(ii) the award agreement pursuant to which such award is granted must be approved by the Committee, and must expressly provide for transferability in a manner consistent with this Section 15.2; and

D-18

(iii) subsequent transfers of transferred awards shall be prohibited except those in accordance with this Section 15.2.

(c) Following transfer, any transferred award shall continue to be subject to the same terms and conditions as were applicable immediately prior to transfer. Unless otherwise provided herein, the events of death, Disability, Retirement and termination of employment or service with respect to an outstanding award shall be in relation to the original grantee Participant notwithstanding an earlier transfer of the award.

15.3: Unfunded Status of Awards; Creation of Trusts. The Plan is intended to constitute an "unfunded" plan for incentive compensation. With respect to any payments not yet made to a Participant pursuant to an award, nothing contained in the Plan or any award shall give any such Participant any rights that are greater than those of a general creditor of the Company; provided, however, that the Committee may authorize the creation of trusts or make other arrangements to meet the Company's obligations under the Plan to deliver cash, Stock, other awards, or other consideration pursuant to any award, which trusts or other arrangements shall be consistent with the "unfunded" status of the Plan unless the Committee otherwise determines.

15.4: No Right to Employment. Participation in this Plan shall not affect the Company's right to discharge a Participant. Unless otherwise specified in the applicable award agreement, (i) an approved leave of absence shall not be considered a termination of employment or service for purposes of an award under the Plan, and (ii) any Participant who is employed by or performs services for a Subsidiary shall be considered to have terminated employment or service for purposes of an award under the Plan if such Subsidiary is sold or no longer qualifies as a Subsidiary of the Company, unless such Participant remains employed by the Company or another Subsidiary.

15.5: Cancellation and Rescission of Awards.

(a) The Committee shall have the discretion with respect to any award granted under this Plan to establish upon its grant conditions under which: (i) the award may be later forfeited, cancelled, rescinded, suspended, withheld or otherwise limited or restricted; or (ii) gains realized by the grantee in connection with an award or an award's exercise may be recovered; provided that such conditions and their consequences are: (A) clearly set forth in the award agreement or other grant document; and (B) fully comply with applicable laws. These conditions may include, without limitation, actions by the Participant which constitute a conflict of interest with the Company, violate the Company's Code of Business Conduct, are prejudicial to the Company's interests, or are in violation of any non-compete agreement or obligation, any confidentiality agreement or obligation, the Company's applicable policies or the Participant's terms and conditions of employment.

(b) The Committee may require, upon exercise, vesting, payment or delivery pursuant to an award, that the Participant certify in a manner acceptable to the

D-19

Company that he or she is in compliance with the terms and conditions of the award agreement.

15.6: Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board nor the submission of the Plan or of any amendment to shareholders for approval shall be construed as creating any limitations on the power of the Board to adopt such other compensatory arrangements as it may deem desirable, including the granting of awards otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

15.7: Successors and Assigns. The Plan and award agreements may be assigned by the Company to any successor to the Company's business. The Plan and any applicable award agreement shall be binding on all successors and assigns of the Company and a Participant, including any permitted transferee of a Participant, the beneficiary or estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant's creditors.

15.8: Taxes. The Company is authorized to withhold from any delivery of shares of Stock in connection with an award, any other payment relating to an award, or any payroll or other payment to a Participant, amounts of withholding and other taxes due or potentially payable in connection with any transaction involving an award, and to take such other action as the Committee may deem advisable to enable the Company and Participants to satisfy obligations for the payment of withholding taxes and other tax obligations relating to any award. This authority shall include authority to withhold or receive shares of Stock or other consideration and to make cash payments in respect thereof in satisfaction of withholding tax obligations. To enable the Company to meet any applicable federal, state or local withholding tax requirements arising as a result of the grant, vesting, or exercise of an award, the Participant (or the Participant's estate) shall pay the Company the amount of tax to be withheld or may elect to satisfy such obligation:

(a) by having the Company withhold shares of Stock that otherwise would be delivered to the Participant pursuant to the granting, payment, vesting, or exercise of an award (as the case may be), for which the tax is being withheld;

(b) by delivering to the Company other shares of Stock owned by the Participant prior to the granting, payment, vesting, or exercise of an award (as the case may be); or

Such an election shall be made prior to the date to be used to determine the tax to be withheld. The value of any share of Stock to be withheld by the Company or delivered to the Company pursuant to this Section 15.8 shall be the Market Price on the date used to determine the amount of tax to be withheld.

D-20

15.9: Compliance with Laws and Obligations. The Company shall not be obligated to issue or deliver shares of Stock in connection with any award or take any other action under the Plan in a transaction subject to the registration requirements of any applicable securities law, any requirement under any listing agreement between the Company and any securities exchange or automated quotation system, or any other law, regulation, or contractual obligation of the Company, until the Company is satisfied that such laws, regulations, and other obligations of the Company have been complied with in full. Certificates representing shares of Stock issued under the Plan will be subject to such stop-transfer orders and other restrictions as may be applicable under such laws, regulations, and other obligations of the Company, including any requirement that a legend or legends be placed thereon.

15.10: No Right to Awards; No Shareholder Rights. No Participant or other person shall have any claim to be granted any award under the Plan, and there is no obligation for uniformity of treatment of Participants, employees, consultants, or directors. No award shall confer on any Participant any of the rights of a shareholder of the Company unless and until shares of Stock are duly issued or transferred and delivered to the Participant in accordance with the terms of the award.

15.11: Severability of Provisions. If any provision of the Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions hereof, and the Plan shall be construed and enforced as if such provisions had not been included.

Section 16: Amendment, Suspension, or Termination.

16.1: The Board may suspend, terminate, or amend the Plan, including, but not limited to, such amendments as may be necessary or desirable resulting from changes in the federal income tax laws and other applicable laws, but may not, without the affirmative vote of a majority of all votes duly cast on the matter at a meeting of the stockholders of the Company (provided that the total votes cast on the matter represent over 50% of the shares entitled to vote on the matter) (a) increase the total number of shares of Stock that may be optioned or granted under this Plan; (b) amend Section 6.3 with respect to re-pricing of Stock Option Awards or (c) amend the Plan in any manner that would require stockholder approval under applicable law.

16.2: It is the Company's intent that the Plan comply in all respects with Rule 16b-3 under the Exchange Act and any related regulations. In addition, it is the intent of the Company that the Plan and applicable awards under the Plan comply with the applicable provisions of sections 162(m), 422, and 409A of the Code. If any provision of this Plan is later found not to be in compliance with Rule 16b-3 under the Exchange Act or the applicable provisions of sections 162(m), 422, and 409A of the Code and regulations thereunder, the provisions shall be deemed null and void. To the extent that any legal requirement of section 16 of the Exchange Act or sections 162(m), 422, or 409A of the Code as set forth in the Plan ceases to be required under

D-21

section 16 of the Exchange Act or sections 162(m), 422, or 409A of the Code, that Plan provision shall cease to apply. The Committee may revoke any award if it is contrary to law or modify an award to bring it into compliance with any valid and mandatory government regulation. All grants to, and exercises of options by Executive Officers under this Plan shall be executed in accordance with the requirements of Section 16 of the Exchange Act and regulations promulgated thereunder.

Section 17: Governing Law.

The validity, construction and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Connecticut and applicable federal law.

Section 18: Effective Date and Duration of the Plan.

This Plan shall be effective as of April 27, 2006. No award shall be granted under this Plan on or after April 26, 2016.
