PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

To be held on August 12, 2009

This proxy statement is furnished in connection with the solicitation of proxies by and on behalf of our Board of Directors for use at our Annual Meeting of Stockholders to be held at the offices of Foley Hoag LLP, Seaport World Trade Center West, 155 Seaport Boulevard, Boston, Massachusetts on August 12, 2009 and at any adjournment or adjournments thereof. We are a Delaware corporation and our principal executive offices are located at 22 Cherry Hill Drive, Danvers, Massachusetts 01923.

We will bear any cost of solicitation. Some of our officers and employees may solicit proxies by correspondence, telephone or in person, without extra compensation. We may also pay to banks, brokers, nominees and other fiduciaries their reasonable charges and expenses incurred in forwarding proxy material to their principals. It is expected that this proxy statement and the accompanying proxy will be mailed to our stockholders on or about July 15, 2009.

We have fixed the close of business on June 24, 2009 as the record date for the Annual Meeting. Only stockholders of record at the close of business on June 24, 2009 will be entitled to receive notice of, and to vote at, the Annual Meeting. As of June 24, 2009, there were outstanding and entitled to vote 37,343,924 shares of our common stock, $.01 par value per share. Our by-laws require that a majority in interest of all stock issued, outstanding and entitled to vote at a meeting shall constitute a quorum. Abstentions and broker non-votes will be counted as present or represented for purposes of determining the existence of a quorum. A “non-vote” occurs when a broker or nominee holding shares for a beneficial owner does not vote on a proposal because the broker or nominee does not have discretionary voting power and has not received instructions from the beneficial owner.

Proposal no. 1 (election of directors) requires the affirmative vote of a plurality of the votes cast by holders of our common stock entitled to vote thereon, provided that a quorum is present. Proposal no. 2 (approval of the amendment to our 2008 Stock Incentive Plan) and Proposal no. 3 (ratification of the appointment of our independent registered public accounting firm) require the affirmative vote of a majority of the votes cast by holders of our common stock entitled to vote thereon, provided that a quorum is present. Abstentions and broker non-votes will not be included in calculating the number of votes cast on Proposal no. 1, Proposal no. 2 and Proposal no. 3. Votes will be tabulated by American Stock Transfer & Trust Company, our transfer agent.

THE ENCLOSED PROXY, IF EXECUTED AND RETURNED, WILL BE VOTED AS DIRECTED ON THE PROXY OR, IN THE ABSENCE OF SUCH DIRECTION, FOR THE NOMINEES FOR DIRECTOR (PROPOSAL NO. 1), FOR THE APPROVAL OF THE AMENDMENT TO OUR 2008 STOCK INCENTIVE PLAN (PROPOSAL NO. 2), AND FOR THE RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (PROPOSAL NO. 3). IF ANY OTHER MATTERS PROPERLY COME BEFORE THE MEETING, THE SHARES REPRESENTED BY THE PROXY WILL BE VOTED BY THE HOLDERS OF THE PROXIES IN ACCORDANCE WITH THEIR BEST JUDGMENT. THE PROXY MAY BE REVOKED AT ANY TIME PRIOR TO EXERCISE BY FILING WITH OUR SECRETARY A WRITTEN REVOCATION, BY EXECUTING A PROXY WITH A LATER DATE, OR BY ATTENDING AND VOTING AT THE MEETING.

Our annual report to stockholders for the fiscal year ended March 31, 2009, including financial statements audited by Deloitte & Touche LLP, our independent registered public accounting firm, is being mailed to each of our stockholders simultaneously with this proxy statement.

PROPOSAL NO.1

ELECTION OF DIRECTORS

Our Board of Directors currently consists of nine directors and is divided into three classes. We refer to these classes as Class I, Class II and Class III. The term of one class of directors expires each year at the annual meeting of stockholders. Each director also continues to serve as a director until his or her successor is duly elected and qualified. This year, the term of the Class II directors is expiring.

Our Board of Directors has nominated Louis E. Lataif, Eric A. Rose and Henri A. Termeer, each to serve as a Class II director for a three-year term, until the 2012 Annual Meeting of Stockholders, and until their respective successors have been duly elected and qualified.

Each of these nominees is currently serving on our Board of Directors. Dr. Rose was elected by our Board of Directors as a Class II director in May 2007. Messrs. Lataif and Termeer were elected by our stockholders as Class II directors at our Annual Meeting of Stockholders in August 2006. The term of each of Messrs. Lataif and Termeer and Dr. Rose will expire at the upcoming annual meeting.

If any nominee at the time of the election is unable or unwilling to serve or is otherwise unavailable for election, and our Board of Directors designates another nominee, the persons named as proxies will vote the proxy for such substitute, if any. Our Board of Directors has no reason to believe that any of the proposed nominees will be unable or unwilling to serve. The proposed nominees are not being nominated pursuant to any arrangement or understanding with any person.

Our Board of Directors recommends that you vote FOR the election of Louis E. Lataif, Eric A. Rose and Henri A. Termeer.

PROPOSAL NO.2

APPROVAL OF THE AMENDMENT TO OUR

2008 STOCK INCENTIVE PLAN

On July 8, 2009, our Board of Directors amended, subject to stockholder approval, our 2008 Stock Incentive Plan to increase the number of shares available for issuance under the 2008 Stock Incentive Plan from 2,000,000 to 3,800,000. If our stockholders do not approve the amendment, our 2008 Stock Incentive Plan will remain in effect and the total number of shares that may be issued pursuant to awards granted under our 2008 Stock Incentive Plan will remain at 2,000,000. These amounts are in addition to additional shares available under the 2008 Stock Incentive Plan based on awards available for grant under our prior stock incentive plans, as described further below. Approval of the amendment to our 2008 Stock Incentive Plan requires the affirmative vote of a majority of the votes cast by holders of our common stock entitled to vote thereon, provided that a quorum is present.

Reasons underlying Proposal No. 2

We are submitting Proposal No. 2 for stockholder approval to ensure that we will have a sufficient number of shares available under our 2008 Stock Incentive Plan to enable us to attract and retain executive officers, outside directors and other key employees in a fashion that the board of directors believes is beneficial to our firm and its stockholders. As of June 30, 2009, we had:

•

stock options to purchase 5,659,257 shares of our common stock are outstanding under our various stock incentive plans, at a weighted average exercise price of $10.66 per share, and with an estimated weighted average remaining life of 7.28 years;

•

431,125 shares of restricted stock are outstanding under our various stock incentive plans; and

•

473,738 shares of our common stock remained available for issuance under our 2008 Stock Incentive Plan, and no shares of our common stock may be issued under our other stock incentive plans. This number may be increased to the extent shares issued under our prior stock incentive plans are forfeited in the future, as further described below.

Stockholder approval of the amendment to our 2008 Stock Incentive Plan has certain tax benefits. Our 2008 Stock Incentive Plan allows us to award “incentive stock options,” which receive favorable tax treatment under the Internal Revenue Code. The stock option grants under our 2008 Stock Incentive Plan cannot qualify as incentive stock options unless the increase is approved by our stockholders.

Additionally, our 2008 Stock Incentive Plan is also specifically designed to preserve our ability to deduct the compensation we pay certain executive officers for income tax purposes. Section 162(m) of the Internal Revenue Code generally prevents us from deducting more than $1.0 million in compensation each year for our chief executive officer and each of our three most highly compensated executive officers other than the chief executive officer or chief financial officer. Compensation treated as “qualified performance-based compensation” under Section 162(m) is not subject to this limitation. Any awards granted under our 2008 Stock Incentive Plan may be treated as “qualified performance-based compensation” only if the plan is approved by a majority vote of our stockholders.

Finally, as an issuer listed on the Nasdaq Global Market, we are required by the rules of the Nasdaq Stock Market to obtain stockholder approval of any stock option or purchase plan or other equity compensation arrangement under which our officers, directors, employees or consultants may acquire shares of our common stock, prior to our issuance of securities under such a plan.

Our Board of Directors recommends that you vote FOR the amendment to our 2008 Stock Incentive Plan.

Summary of our 2008 Stock Incentive Plan

The following is a summary of certain of the key provisions of our 2008 Stock Incentive Plan. The full text of our 2008 Stock Incentive Plan, as amended, is set forth at Appendix A.

Purpose of the Plan

The purpose of our 2008 Stock Incentive Plan is to encourage and enable our officers, directors, employees and other persons providing services to us to acquire a proprietary interest in our company. It is anticipated that providing such persons with a direct stake in our welfare will assure a closer identification of their interests with our interests and those of our stockholders, thereby stimulating their efforts on our behalf and strengthening their desire to remain associated with us. Our 2008 Stock Incentive Plan was originally adopted by our Board of Directors on July 9, 2008 and approved by our stockholders at our Annual Meeting of Stockholders held on August 13, 2008.

Types of awards authorized by the Plan

Our 2008 Stock Incentive Plan authorizes the grant of the following types of incentive and performance awards to our officers, employees, and other persons providing services to us or our subsidiaries:

•

options to purchase shares of our common stock intended to qualify as incentive stock options, as defined in Section 422 of the Internal Revenue Code;

•

non-statutory options, which do not qualify as incentive stock options;

•

restricted stock awards consisting of shares of our common stock subject to restrictions;

•

unrestricted stock awards, consisting of shares of our common stock issued or sold without any restrictions under the plan;

•

performance share awards, entitling the recipient to acquire shares of our common stock upon the attainment of specified performance goals; and

•

stock appreciation rights, entitling the recipient, upon exercise of the rights, to receive from us a number of shares of our common stock having an aggregate fair market value equal to the difference in the fair market value of the stock on the exercise date and the exercise price of the right.

As of June 30, 2009, eight directors (excluding Mr. Minogue, who is also an officer), six executive officers and approximately 385 non-executive officer employees were eligible to participate in the 2008 Stock Incentive Plan.

Shares subject to the plan

All of the shares issued under our 2008 Stock Incentive Plan or by which awards granted under the plan are measured are shares of our authorized but unissued common stock. The maximum number of shares issuable under the plan is currently 2,000,000 (counted as further described below), and if the amendment is approved, will be increased to 3,800,000. The plan automatically increases this maximum, but not by more than a total of 4,500,000 additional shares, as follows:

•

308,688 shares were added to the plan, representing the total number of shares that were available for future awards under our 1989 Non-Qualified Stock Option Plan for Non-Employee Directors, our 1998 Equity Incentive Plan and our 2000 Stock Incentive Plan as of August 13, 2008, the date our stockholders approved the 2008 Stock Incentive Plan; and

•

Up to 4,191,312 additional shares may be added to the plan to the extent that awards issued under our 1989 Non-Qualified Stock Option Plan for Non-Employee Directors, our 1998 Equity Incentive Plan and our 2000 Stock Incentive Plan are forfeited after August 13, 2008.

Each share of stock issued pursuant to a stock option or stock appreciation right counts as one share against the maximum number of shares issuable under our 2008 Stock Incentive Plan, while each share of stock issued pursuant to any other type of award counts as 1.5 shares against the maximum number of shares issuable under the plan. The plan adjusts the maximum number of shares if we effect a capital readjustment or pay a stock dividend without receiving compensation in return. Whenever any outstanding award under the plan expires or terminates other than by exercise or payment (with the exception of any shares used to pay the exercise price of a stock option or to pay withholding taxes with respect to an award under the plan), the corresponding shares of common stock may again be the subject of plan awards. However, shares used to pay the exercise price of a stock option, to pay withholding taxes, and shares subject to stock appreciation rights that are not issued upon the exercise of such stock appreciation rights are not available for future plan awards. Our 2008 Stock Incentive Plan authorizes awards of up to an aggregate of 300,000 shares of common stock to any one participant per year.

The last sales price of our common stock on June 30, 2009, as reported on the Nasdaq Global Market, was $8.82 per share.

Administration of the Plan

Our 2008 Stock Incentive Plan is administered by the Compensation Committee of our Board of Directors, all of whose members qualify both as “non-employee directors” within the meaning of Section 16b-3 under the Securities Exchange Act of 1934 and as “outside directors” within the meaning of Section 162(m) of the Internal Revenue Code. In addition, the Compensation Committee may establish an additional single-member committee (consisting of an executive officer) that may grant awards to non-executive officers and make all other determinations under the 2008 Stock Incentive Plan with respect to such awards. The Board of Directors has established such a single-member committee, consisting of Mr. Minogue.

The Compensation Committee or the single-member committee selects the individuals who receive awards and determines the terms of each award, subject to the provisions of the 2008 Stock Incentive Plan. The Compensation Committee also has the power to make changes to outstanding awards under the 2008 Stock Incentive Plan, including the power to accelerate the vesting schedule of any award and to extend the expiration date of any option or stock appreciation right. However, the Compensation Committee does not have authority to reduce the exercise price of any stock option or stock appreciation right after the date of grant.

Upon granting an award under our 2008 Stock Incentive Plan, the Compensation Committee may require the award recipient to agree to enter into a standard “lock-up agreement,” which would prevent the recipient from disposing of any shares issued under the award for a period of not more than 215 days following the effective date of our registering any of our securities with the Securities and Exchange Commission.

Stock Options

Our 2008 Stock Incentive Plan authorizes the grant of options to purchase our common stock intended to qualify as incentive stock options, as defined in Section 422 of the Internal Revenue Code, and options that do not so qualify, which are non-statutory options. Incentive options may be granted under our 2008 Stock Incentive Plan to our employees or the employees of any of our subsidiaries, including directors and officers who are our employees or employees of any of our subsidiaries. Non-statutory options may be granted under our 2008 Stock Incentive Plan to our employees, or any employees of our subsidiaries, and to directors, consultants and other persons who render services to us or our subsidiaries, regardless of whether they are our employees or employees of any subsidiary.

The exercise price of any option granted under our 2008 Stock Incentive Plan must equal or exceed the fair market value of our common stock on the date of grant. The exercise price of incentive options granted under the 2008 Stock Incentive Plan to a person who owns more than 10% of the combined voting power of all classes of our outstanding capital stock or the capital stock of any of our subsidiaries, referred to as a greater-than-ten-percent stockholder, must equal or exceed 110% of the fair market value of our common stock on the date of grant.

Each option expires no later then ten years after the date of grant or, in the case of an incentive option granted to a greater-than-ten-percent stockholder, five years after the date of grant. The aggregate fair market value, at the time of grant, of shares issuable pursuant to incentive options that are exercisable for the first time in any calendar year may not exceed $100,000, unless a greater amount is permitted by law.

Except as otherwise provided by the Compensation Committee with respect to non-statutory options, options are not transferable except by will or by laws of descent and distribution, and during the holder’s lifetime are exercisable only by the holder. The Compensation Committee determines, in its discretion, how and when non-statutory options will terminate. Incentive stock options will terminate as follows:

•

If the option holder’s employment with us terminates because of death, his or her incentive option may be exercised, to the extent exercisable at the time of termination, for a period of 180 days from the date of termination of employment or the stated expiration date of the option, whichever is earlier.

•

If the option holder’s employment with us terminates because of disability, as defined in the 2008 Stock Incentive Plan, his or her incentive option may be exercised, to the extent exercisable at the time of termination, for a period of 90 days from the date of termination of employment or the stated expiration date of the option, whichever is earlier.

•

If the option holder’s employment with us terminates because of retirement in accordance with our normal retirement policies, his or her incentive option is exercisable for a period of 90 days from the date of termination of the option holder’s employment or the stated expiration date of the option, whichever is earlier.

•

If the option holder’s employment is terminated by us for cause, as defined in our 2008 Stock Incentive Plan, his or her incentive option will immediately terminate.

•

If the option holder’s employment with us terminates for any reason other than those listed above, his or her incentive option may be exercised, to the extent it was exercisable at the time of termination, for a period of 30 days from the date of termination of employment or until the stated expiration date of the option, whichever is earlier.

The holder of an option may pay the exercise price for the shares subject to the option (a) in cash or by bank check in an amount equal to the exercise price for such shares, or (b) to the extent provided in the applicable agreement setting forth the terms and conditions of the option, by any one or more of the following: (i) in shares of our common stock having a fair market value equal to the aggregate exercise price of the option being exercised, (ii) by delivery of irrevocable instructions to a broker to deliver to us cash or a check payable to us for the aggregate exercise price, provided that the holder and the broker enter into an indemnity agreement or any other agreement that the Compensation Committee requires as a prerequisite to this method of payment, (iii) by reducing the number of shares that would otherwise be issued upon option exercise by a number of shares of common stock having a fair market value equal to the aggregate exercise price of the option being exercised, or (iv) by any combination of such methods of payment.

Restricted Stock Awards

The Compensation Committee may grant awards of restricted stock on the terms, conditions and restrictions it designates in an award agreement. The recipient of a restricted stock award is issued shares of our common stock subject to the forfeiture, transferability and other restrictions, if any, set forth in our 2008 Stock Incentive Plan and the award agreement. The forfeiture and transferability restrictions are removed as the award vests based on a predetermined period provided in the award agreement, or based on pre-established performance goals, objectives and other conditions provided in the award agreement.

A recipient of a restricted stock award acquires all of the rights of a holder of our common stock with respect to the restricted shares issued pursuant to the award, whether vested or not, including the right to vote and to receive dividends. However, we may hold certificates representing the recipient’s restricted shares until all

applicable restrictions lapse or are released. The recipient must forfeit all unvested restricted shares when the recipient’s employment with or provision of services to us terminates for any reason. The Compensation Committee may waive any terms and conditions set forth in any restricted stock award agreement, subject to the terms of the 2008 Stock Incentive Plan.

Unrestricted Stock Awards

The Compensation Committee may also grant awards of unrestricted stock, which are free of any restrictions under the 2008 Stock Incentive Plan. These may be granted or sold at a purchase price determined by the Compensation Committee, including in respect of past services or other valid consideration.

Performance Share Awards

The Compensation Committee may grant a performance share award to any of our officers, directors, employees, or other persons providing services to us. The Compensation Committee may determine whether and to whom performance share awards may be made, the periods during which the performance is to be measured and any other limitations and conditions applicable to the award, or to common stock issuable under the award. If the recipient of a performance share award attains the performance goals described in the performance share award agreement, we will issue the common stock to the participant as soon as practicable thereafter, but in no event later than two and one-half months after the calendar year in which the performance goal is attained.

Stock Appreciation Rights

The Compensation Committee may grant stock appreciation rights to any of our officers, directors, employees, or other persons providing services to us. A stock appreciation right entitles the recipient, upon exercise of the rights, to receive from us a number of shares of our common stock having an aggregate fair market value equal to the difference in the fair market value of the stock on the exercise date and the exercise price stated in the right agreement provided to the participant by the Compensation Committee (which exercise price will equal or exceed the fair market value of our common stock on the date of grant of the right). Each stock appreciation right expires no later then ten years after the date of grant.

Amendment of our 2008 Stock Incentive Plan

According to the terms of the 2008 Stock Incentive Plan, our Board of Directors may amend or discontinue the 2008 Stock Incentive Plan at any time.

Federal Income Tax Information with Respect to our 2008 Stock Incentive Plan

The holder of a non-statutory option recognizes no income for federal tax purposes on the grant of the option. On the exercise of such non-statutory option, the difference between the fair market value of the underlying shares of common stock on the exercise date and the option exercise price is treated as compensation to the holder of the option taxable as ordinary income in the year of exercise. Such fair market value becomes the basis for the underlying shares which will be used in computing any capital gain or loss upon disposition of such shares. The capital gain or loss will be long-term capital gain or loss if the shares were held for more than one year after the exercise of the option.

The holder of an incentive option recognizes no income for federal income tax purposes on the grant of the option. Except as provided below with respect to the alternative minimum tax, there is no tax upon exercise of an incentive option. If the holder does not dispose of the shares acquired upon exercise of the incentive option within two years from the date of the grant of the incentive option or within one year after exercise of the incentive option, any gain realized by the option holder on the subsequent sale of those shares will be treated as long-term capital gain for federal income tax purposes. If the holder sells the shares before the expiration of such

two-year and one-year periods, known as a disqualifying disposition, the difference between the lesser of the value of the shares at the date of exercise or at the date of sale and the exercise price of the incentive option will be treated as compensation to the option holder taxable as ordinary income and the excess gain, if any, will be treated as capital gain. The capital gain will be long-term capital gain if the shares were held for more than one year after the exercise of the option.

The excess of the fair market value of the underlying shares of common stock over the exercise price at the time of exercise of an incentive option will constitute an item of tax preference for purposes of the alternative minimum tax. Taxpayers who will incur the alternative minimum tax will be allowed a credit which may be carried forward indefinitely to be used as a credit against the taxpayer’s regular tax liability in a later year; however, the alternative minimum tax credit cannot reduce the regular tax below the alternative minimum tax for that carryover year.

The recipient of a restricted stock award usually recognizes ordinary income only as the shares of restricted stock issued in connection with the award vest. Upon vesting, the recipient recognizes ordinary income in an amount equal to the excess, if any, of the fair market value of the vested shares at the time of vesting over any amount paid by the recipient for the vested shares. Upon the subsequent resale of such vested shares, the recipient will recognize capital gain or loss, as the case may be, in an amount equal to the difference between the amount the recipient receives in exchange for the vested shares and the fair market value of the vested shares at the time of vesting. The gain or loss will be long-term capital gain or loss, if more than one year has passed since the shares vested.

However, the recipient of a restricted stock award may elect to recognize ordinary income upon the receipt, not the vesting, of shares of restricted stock in connection with the award in accordance with Section 83(b) of the Internal Revenue Code. In this case, the recipient recognizes ordinary income in an amount equal to the excess, if any, of the fair market value of the shares at the time the recipient received the shares over the amount the recipient paid for the shares. Upon the subsequent resale of such vested shares, the recipient will recognize capital gain or loss, as the case may be, in an amount equal to the difference between the amount the recipient receives in exchange for the vested shares and the fair market value of the vested shares at the time the recipient received the shares. The gain or loss will be long-term capital gain or loss, if at the time of such resale more than one year has passed since the recipient received the shares.

The recipient of an unrestricted stock award will recognize as ordinary income the difference between the fair market value of the common stock granted pursuant to the unrestricted stock award and the amount, if any, the recipient paid for such stock in the taxable year the recipient receives the common stock. The recipient’s basis in any common stock received pursuant to the grant of an unrestricted stock award will be equal to the fair market value of the common stock on the date of receipt of the common stock. Any gain realized by the recipient of an unrestricted stock award upon a subsequent disposition of such common stock will be treated as long-term capital gain, if at the time of such disposition more than one year has passed since the recipient received the shares.

The recipient of a performance share award recognizes no income until the recipient receives shares of our common stock in connection with the award. Upon the receipt of shares, the recipient recognizes ordinary income in an amount equal to the fair market value of the common stock issued pursuant to the award. The recipient’s basis in common stock received pursuant to a performance share award will be equal to the fair market value of the common stock on the date of receipt of the common stock. Any gain realized by the recipient of a performance share award upon a subsequent disposition of such common stock will be treated as long-term capital gain if at the time of such disposition more than one year has passed since the recipient received the shares.

The recipient of a stock appreciation right recognizes no income until the recipient receives shares of our common stock in connection with the right. Upon the receipt of shares, the recipient recognizes ordinary income in an amount equal to the fair market value of the common stock issued pursuant to the award. The recipient’s

basis in common stock received pursuant to a stock appreciation right will be equal to the fair market value of the common stock on the date of receipt of the common stock. Any gain realized by the recipient of a stock appreciation right upon a subsequent disposition of such common stock will be treated as long-term capital gain, if at the time of such disposition more than one year has passed since the recipient received the shares.

Subject to certain limitations, we may generally deduct on our corporate income tax returns an amount equal to the amount recognized as ordinary income by a recipient of an award under our 2008 Stock Incentive Plan in the year in which the recipient recognizes ordinary income upon the exercise of a non-statutory stock option, the disqualifying disposition of an incentive stock option, the receipt or vesting of shares of stock in connection with a restricted stock award, or the receipt of shares of stock in connection with an unrestricted stock award, a performance share award or a stock appreciation right.

Section 162(m) of the Internal Revenue Code generally prevents us from deducting more than $1.0 million in compensation each year for our chief executive officer and each of our three most highly compensated executive officers other than the chief executive officer or chief financial officer. Performance-based compensation that meets criteria established by the Internal Revenue Service, however, is not subject to this limitation. Some of the awards that we grant under our 2008 Stock Incentive Plan may not qualify as such performance-based compensation. Accordingly, we may be unable to deduct some or all of the amounts that may be recognized as ordinary income by these executive officers.

Our 2008 Stock Incentive Plan is not subject to the provisions of the Employee Retirement Income Security Act of 1974, nor is the 2008 Stock Incentive Plan qualified under Section 401(a) of the Internal Revenue Code.

New Plan Benefits. Except as described below, the following table sets forth information concerning the benefits or amounts under our 2008 Stock Incentive Plan, amended as set forth in Proposal Two, that we can determine will be received by:

•

each named executive officer that is currently an executive officer;

•

all current executive officers, as a group;

•

all current directors who are not executive officers, as a group; and

all employees who are not executive officers, as a group.

The information in the following table is limited to the annual automatic stock options to be granted to our non-employee directors in connection with our 2009 annual meeting of stockholders. Except for these awards, we are unable to determine the dollar value and number of awards that may be received by or allocated to any of the persons who are eligible to participate in our 2008 Stock Incentive Plan because awards are granted by the Compensation Committee and the single-member committee on a discretionary basis.

The equity grants we made to our named executive officers during fiscal 2009 are described elsewhere in this proxy statement. Our Chief Executive Officer, Michael R. Minogue, was granted 86,667 restricted shares and stock options to purchase 43,333 shares of our common stock in May 2008, at an exercise price of $13.80 per share, based upon and in recognition of his performance during the year ended March 31, 2008. In August 2008, following stockholder approval of our 2008 Stock Incentive Plan, Mr. Minogue was granted, based upon and in additional recognition of his performance during the year ended March 31, 2008, 93,750 restricted shares and stock options to purchase 93,750 shares of our common stock at an exercise price of $18.63 per share, that vest based on certain performance milestones for fiscal years 2009, 2010 and 2011. Based upon and in recognition of his performance during the year ended March 31, 2009, he was granted 278,500 stock options in May 2009 with an exercise price of $5.86, of which 130,500 vest based on certain performance milestones for fiscal year 2010 performance.

Because the grant of awards under the plan is discretionary, the persons and groups listed in the following table may receive additional awards under our 2008 Stock Incentive Plan. Our 2008 Stock Incentive Plan limits the number of shares of common stock subject to awards granted under the plan to a single recipient in any calendar year to 300,000.

PROPOSAL NO.3

RATIFICATION OF APPOINTMENT OF OUR

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Proposal no. 3 concerns the ratification of the appointment by our audit committee of Deloitte & Touche LLP to be our independent registered public accounting firm for the fiscal year ending March 31, 2010.

Ratification of Appointment for Fiscal 2010

Under rules of the Securities and Exchange Commission, or SEC, and the Nasdaq Stock Market, the appointment of our independent registered public accounting firm is the direct responsibility of our Audit Committee. Although ratification by our stockholders of this appointment is not required by law, our Board believes that seeking stockholder ratification is a good practice, which provides stockholders an avenue to express their views on this important matter.

Our Audit Committee has reappointed Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending March 31, 2010. Our Board of Directors recommends that stockholders vote to ratify the appointment. If our stockholders do not ratify the appointment of Deloitte & Touche LLP, the Audit Committee may reconsider its decision. In any case, the Audit Committee may, in its discretion, appoint a new independent registered public accounting firm at any time during the year if it believes that such change would be in our best interest and the best interest of our stockholders. We expect that representatives of Deloitte & Touche LLP will be present at the Annual Meeting. They will have an opportunity to make a statement if they wish and will be available to respond to appropriate questions from stockholders.

Our Board of Directors recommends that you vote FOR the proposal to ratify the appointment by our Audit Committee of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal 2010.

Each of Drs. Austen and Rose and Messrs.

The annual stock options granted in fiscal 2009 on August 13, 2008 had a grant date fair value of $103,218 computed in accordance with SFAS No. 123(R) for each of the following directors: W. Gerald Austen, Ronald W. Dollens, Louis E. Lataif, Desmond H. O’Connell, Jr., Eric A. Rose, Martin P. Sutter and Henri A. Termeer. The annual stock options granted in fiscal 2009 on August 13, 2008 to Dorothy E. Puhy had a grant date fair value of $116,120 computed in accordance with SFAS No. 123(R). The stock options granted on May 20, 2008 to Martin P. Sutter had a grant date fair value of $164,490 computed in accordance with SFAS 123(R). Generally, the grant date fair value is the full amount that we would expense in our financial statements over the vesting schedule of the award. In calculating these values, we used the assumptions described in Note 11 to our consolidated financial statements included in our annual report on Form 10-K filed with the SEC for the year ended March 31, 2009. For stock options, fair value is calculated using the Black-Scholes value on the grant date. Pursuant to SEC rules, the amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions.

Compensation Committee Interlocks and Insider Participation

Our Compensation Committee consists of Ronald W. Dollens (Chair), W. Gerald Austen and Henri A. Termeer. No member of our Compensation Committee is a former or current officer or employee. Mr. Minogue, while not a member of the Compensation Committee, makes recommendations to the Compensation Committee regarding the compensation of executive officers other than himself, including the awards of stock options and restricted stock, and often participates in the Committee’s deliberations but does not vote on such matters. None of our executive officers serves as a member of the Board of Directors or Compensation Committee of any entity that has one or more executive officers serving as members of our Board of Directors or Compensation Committee.

Certain Relationships and Related-Person Transactions

There were no related-person transactions in fiscal 2009. Under its charter, the Audit Committee of the Board of Directors is responsible for reviewing any proposed related-party transaction, as defined under the rules of the Nasdaq Stock Market, and, if appropriate, approving such transaction. In addition, our conflict of interest policy provides that specified conflict of interest transactions are either prohibited or require the prior approval of our President. Examples of these conflict of interest transactions include serving as a director, officer or employee of or consultant to any competitor or any entity that does business with us or having a substantial direct or indirect interest in any entity that does business with us. Other than the foregoing, we have no established policies or procedures, written or otherwise, for the review, approval or ratification of transactions with related persons.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This compensation discussion and analysis describes the material elements of our compensation programs as they relate to our executive officers who are listed in the following compensation tables, who are sometimes referred to as the “named executive officers”. This compensation discussion and analysis focuses on the information contained in the following tables and related footnotes, but also describes other arrangements and actions taken since March 31, 2009 to the extent such discussion enhances the understanding of our executive compensation for fiscal 2009.

Overview

The Compensation Committee oversees and administers our executive compensation program. The primary objectives of the compensation programs are:

•

to attract, retain and motivate key executives and to reward executives for achieving our objectives, and

•

to reward superior financial, strategic and operational performance that is achieved in a manner consistent with our team-oriented values.

Our executive officers are assessed and ranked on the basis of demonstrated results relative to pre-established goals, as well as subjective leadership qualities. The ranking that an executive officer receives each year generally has a direct and material impact on the cash bonus, option and equity grants that such executive officer receives as well as his or her annual increase in base salary. The compensation of executive officers in fiscal 2009 consisted of base salary, cash bonus, the grant of options and restricted stock and participation in benefit plans generally available to all employees. The largest component of our annual compensation program is base salary, followed by cash bonuses. Equity incentives offer the opportunity to be a more substantial component of compensation provided that the management team is successful in achieving the corporate goals and the price of our stock appreciates. As of March 31, 2009, equity incentives have been awarded to our executives in the form of grants of stock options and restricted stock awards.

Compensation Consultants and Peer Groups

To assist us in making our initial compensation determinations in fiscal 2009, including our salary determinations and our decisions about equity incentive compensation, we were advised by the compensation consultant Dolmat Connell & Partners. We engaged the compensation consultant Radford, part of Aon Corporation, to advise us on our final compensation determinations for fiscal 2009 and for our initial compensation determinations for fiscal 2010.

We look at peer group data provided to us by our compensation consultants for comparative purposes. The peer group data we looked at when determining fiscal 2009 salary and bonus targets consisted of the following 14 companies: Cerus Corporation, Conceptus, Inc., Cynosure, Inc., IRIS International, Inc., Kensey Nash Corporation, Micrus Endovascular Corporation, NxStage Medical, Inc., Regeneration Technologies, Inc., Somanetics Corporation, Stereotaxis, Inc., SurModics, Inc., Synovis Life Technologies, Inc., The Spectranetics Corporation, and Vital Images, Inc. When determining fiscal 2009 bonus payments and fiscal 2010 salaries we looked at a peer group of 22 companies: Accuray Incorporated, AngioDynamics, Inc., ATS Medical, Inc., Cerus Corporation, Conceptus, Inc., Cryolife, Inc., Cynosure, Inc., ICU Medical Inc., Insulet Corporation, Kensey Nash Corporation, Merit Medical Systems, Inc., Micrus Endovascular Corporation, NxStage Medical, Inc., RTI Biologics, Inc., SonoSite, Inc., The Spectranetics Corporation, Stereotaxis, Inc., SurModics, Inc., Synovis Life Technologies, Inc., VentraCor Ltd., VNUS Medical Technologies, Inc., and Volcano Corporation. These companies were chosen based on having either a similar employee size or revenue and also having either a similar gross margin or market value. We also looked at competitive market data from a number of survey sources.

We generally strive to be at the 50^th percentile for base salary among our peer group and to provide a 75^th percentile opportunity, based on performance, with respect to cash bonus and equity awards. However, we also take into account the relatively higher cost-of-living in the greater Boston area where we are located.

Compensation Program Elements

Base Salary

We pay our named executive officers base salary to provide a baseline level of compensation that is both competitive with the external market and commensurate with each employee’s past performance, experience, responsibilities and skills. We generally target base salaries for our named executive officers around the median of our external market peers and then make adjustments based on the factors described above, as well as the relatively higher cost-of-living in the greater Boston area where we are located. In particular, based on his year’s of experience, long tenure at our company, and the additional quality and regulatory responsibilities that he has compared to his peers at other companies, we pay an additional premium to our Senior Vice President of Engineering and Quality. The Chief Executive Officer recommended and the Compensation Committee approved base salary increases for fiscal 2009 for all of our named executive officers, other than our Chief Executive Officer, in the range of 3% to 12%, based on performance and the prior year’s salary. Our Compensation Committee approved a base salary increase of 5% for fiscal 2009 for our Chief Executive Officer. These increases came a year after we had limited salary increases to a modest 2% for all of our named executive officers. For fiscal 2010, our Compensation Committee recently decided to increase the base salary of three of our named executive officers, by 5% to 11%. The salaries of our Chief Executive Officer and Chief Financial Officer for fiscal 2010 were not changed. Our Chief Financial Officer joined us during the last few months of fiscal 2009, and his salary also reflects an amount we thought would be competitive in recruiting him to join our Company.

Cash Bonus

We maintain an annual cash bonus program, the purpose of which is to motivate and reward the attainment of our annual financial, strategic and operational goals.

The Compensation Committee establishes and approves all Company focused goals based on recommendations made by management. Individual performance goals for named executive officers are recommended by Mr. Minogue and approved by the Compensation Committee, with those for Mr. Minogue approved by the Compensation Committee and the Lead Director.

Actual incentive awards can range from zero to more than target levels, depending on the degree to which the Company and the individual attain the pre-established goals for the particular year. Based on Company and individual performance toward specified goals, an individual leadership assessment and an executive’s base salary relative to market, total cash compensation may be above or below market median.

For all named executive officers, annual incentive opportunities for fiscal 2009 were targeted at a level that represents a meaningful portion of our executive’s current base salary. For fiscal 2009, target bonus opportunities for our named executive officers other than Mr. Minogue ranged from 38% to 52% of base salary. Mr. Minogue’s fiscal 2009 target bonus opportunity was equal to 100% of his base salary, which the Compensation Committee believes is a standard level in the industry. For fiscal 2009, the Compensation Committee (and, in the case of Mr. Minogue, the Compensation Committee and the Lead Director) selected goals that were intended to strike a balance among fiscal, strategic and operational performance. The Compensation Committee believes that the selected goals were challenging for the management team and the Company to achieve. The Compensation Committee believes that the challenging nature and the balance of performance goals most effectively align management incentives with enhancement of long-term stockholder value.

We use a series of objective and subjective performance goals in order to determine the relative performance of each executive officer during the year. Each goal is set on a scale of 1 through 4, and the

weighted average rating of all goals is determined at the end of the year. An average rating of 3 generally yielded a recommendation of approximately 100% of bonus target, while an average rating of 2 yielded a recommendation of approximately 70% of bonus target. These recommendations, however, are not formulaically determined at the beginning of the year. The rating system is a method for determining fiscal year performance against set goals, but the bonus payments are still discretionary. Bonuses for named executive officers other than the Chief Executive Officer are recommended by Mr. Minogue, but the Committee has the discretion to alter actual bonus awards from the Chief Executive Officer’s recommendation, either up or down. In addition, the Committee has complete discretion in determining Mr. Minogue’s annual bonus.

For each named executive officer, 70% of the officer’s fiscal 2009 target bonus opportunity was based on progress toward achievement of both objective and subjective corporate goals, such as meeting revenue targets, reducing expenses, achieving regulatory milestones, improving product performance, and improving manufacturing processes. These performance goals varied by individual based on their respective areas of responsibility and were weighted according to the importance of the goal to our overall strategic objectives for the fiscal year. The revenue targets used in the rating system for fiscal 2009 yielded a rating of 1 for all named executive officers, since our revenues for the fiscal year were below $75 million. Revenue of $80 million would have yielded a rating of 2, revenue of $85 million would have yielded a rating of 3, and this level of revenue combined with profitability for the fourth quarter would have yielded a rating of 4. Other ratings were based on internal metrics related to the execution of internal expense budget items, the launch of Impella, increasing Impella manufacturing capacity, and other internal goals. These goals are generally set so that the expected outcome would be a 2 or a 3 rating, with outcomes of a 4 rating being very difficult to achieve. The remaining 30% of each officer’s fiscal 2009 target bonus opportunity was based on a subjective assessment of the officer’s overall leadership performance.

For fiscal 2009, the Committee endorsed, and did not alter, the bonus amounts proposed by the Chief Executive Officer for the other named executive officers. Actual bonus awards made to our named executive officers other than Mr. Minogue for fiscal 2009 ranged from approximately 70% of the officer’s target bonus to 110% of the officer’s target bonus, with an average award equal to approximately 90% of the target bonus. Mr. Minogue was awarded 100% of his target bonus. These variations from target were reflections of each individual’s degree of success in meeting his performance goals as well as his contribution to our meeting our objectives for the year.

Equity Incentives

Equity incentives are available to the majority of employees to foster a culture of ownership, align compensation with stockholder interests and promote long-term retention and affiliation with the organization. Each year, the Compensation Committee determines the types and sizes of awards to be used for delivering such incentives. In doing so, the Compensation Committee considers the ability of each type and size of award to achieve key compensation objectives (such as employee retention, motivation and attraction), the needs of the business, competitive market practices, dilution and expense constraints, as well as tax and accounting implications.

In determining the level of stock option awards to grant for fiscal 2009, the Compensation Committee followed a process similar to that employed for prior fiscal years. The Compensation Committee approved stock option awards based on individual performance ranking in an effort to ensure that top performing employees receive larger awards than those with average performance. The Compensation Committee believes that the use of a strong performance management system combined with the retention attributes of stock options and restricted stock allows us to effectively retain those employees who have the potential to make the greatest contributions to our long-term success.

For fiscal 2009, the Compensation Committee approved a program awarding stock options and restricted stock awards. The Committee believes that stock options and restricted stock align management incentives with enhancement of long-term stockholder value and also serve as a valuable retention tool for our executive officers.

Our regular stock option grants made during fiscal 2009 vest 25% annually on each anniversary of the date of grant. Half of the restricted stock vests 25% annually on each anniversary of the date of grant, while the other half of the restricted stock grants vested upon the achievement of an objective corporate milestone, the commercial launch of our Impella 2.5 product at up to 100 hospitals. This goal was achieved in September 2008.

In August 2009, following stockholder approval of our 2008 Stock Incentive Plan at our annual meeting, the Committee also made special equity grants to our named executive officers that vest based on objective corporate revenue and profitability targets over the next three fiscal years. These awards took the form of restricted stock for most of our named executive officers and a mix of restricted stock and stock options for our Chief Executive Officer. Pursuant to the terms of the restricted stock award agreements and the stock option agreement, the restricted stock awards and the stock option award will vest in three tranches, which vary in size depending on the employee, conditioned upon the recipient’s continued employment and the achievement of performance milestones related to our revenue for fiscal year 2009 and fiscal year 2010 and the achievement of a specified profitability threshold by the end of fiscal year 2011. Each of the revenue milestones can vest 0%, 40%, 80% or 100% depending on the applicable revenue thresholds that are reached, while the profitability threshold milestone can vest 0%, 80% or 100% depending on the timing that the threshold is met. For the purposes of the milestones, profitability will be calculated excluding certain costs and expenses associated with stock options, research and development and acquisitions. In addition, the awards vest in full upon a change of control to the extent that the relevant time period for achieving the applicable milestone has not yet lapsed. For the awards based on fiscal 2009 revenue, 40% of the equity grant vested and 60% of the equity grant was forfeited. This was a result of vesting targets set at 40% vesting for $72 million in fiscal 2009 revenue, 80% vesting for $80 million in fiscal 2009 revenue and 100% vesting for $88 million in fiscal 2009 revenue.

The Compensation Committee adopted a program containing both stock options and restricted stock because it believes that each form of compensation has strengths and weaknesses in supporting our compensation program objectives and that those objectives are best served by a mixture of the two forms of compensation. In addition to their strong retention value, we feel that stock options and restricted stock support an ownership mentality, encouraging our executives to act in a manner consistent with our long-term interests and those of our stockholders. These stock option grants are qualified as performance-based pay under Section 162(m) of the Internal Revenue Code. Restricted stock awards are not qualified as performance-based pay under Section 162(m) of the Internal Revenue Code; accordingly, compensation expense associated with restricted stock awards will be subject to the $1 million limitation on deductibility for tax purposes for the compensation of certain executive officers.

Our Compensation Committee recently made our annual equity grants for fiscal 2010. The grants made for fiscal 2010 were all in the form of stock options. The Committee determined that based on our current stock price which is lower than historic levels, stock options would provide a better incentive to our employees. Of these stock options granted to our executive officers, 62% vest 25% annually on each anniversary of the date of grant, and 38% vest upon the achievement of an objective corporate profitability target.

Since 1998, we have made our annual merit equity grants in conjunction with our annual performance appraisal process, which takes place after the close of our fiscal year. Establishing a consistent annual grant pattern has allowed us to develop a schedule of events for setting our annual grant date and price. These events include incorporating the results of our internal performance reviews and rankings. The date of each annual merit grant is the date upon which the Compensation Committee approves the individual grants. It has been our practice to hold this Compensation Committee meeting after the announcement of year-end results. Consistent with our historical stock option grant practice, the exercise price of stock options granted as part of the annual merit grant is the closing price of our common stock on the date of grant. Stock options granted to new hires are ordinarily granted and priced on the date of hire.

Other Compensation

The amounts shown in the Summary Compensation Table under the heading “All Other Compensation” represent the value of certain other compensation received, which are described in detail in the accompanying footnotes. Our Chief Executive Officer and our executive officers received the following such benefits in fiscal 2009: matching contributions to our 401(k) plan, which are available to substantially all of our employees, life insurance premiums and long-term disability insurance premiums. Our former Chief Financial Officer also received payment for unused vacation when he resigned from the Company in October 2008. We believe that such perquisites represent standard parts of executive compensation.

Compensation Committee Report

The Compensation Committee has reviewed and discussed with management the contents of the Compensation Discussion and Analysis set forth above. Based on its review and discussion, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference into the Company’s Annual Report on Form 10-K for the year ended March 31, 2009.

The amounts actually paid with respect to fiscal 2009 are reported in the Summary Compensation Table under the heading “Non-Equity Incentive Plan Compensation.” There are no established thresholds or maximums in the plan.

(3)	Represent shares of our common stock subject to restricted stock awards granted under our 2000 Stock Incentive Plan. These shares vest either based on performance milestones or on the third anniversary of the date of grant.

(4)	Awards of stock options were made under our 2000 Stock Incentive Plan and 2008 Stock Incentive Plan. These stock options vest either based on performance milestones or 25% annually beginning on the first anniversary of the date of grant.

(5)	The exercise price of each stock option reported in the table is equal to the closing market price of our common stock on the grant date.

(6)

Amounts shown do not reflect compensation actually received by the executive officer. Instead, the amounts shown reflect the grant date fair values of the awards computed in accordance with SFAS No. 123(R). Generally, the grant date fair value is the full amount that we would expense in our financial statements over the vesting schedule of the award. For stock options, fair value is calculated using the Black-Scholes value on the grant date. In calculating these values, we used the assumptions described in Note 12 to our consolidated financial statements included in our annual report on Form 10-K filed with the SEC for the year ended March 31, 2009. Pursuant to SEC rules, the amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions. The actual amount of compensation that may be earned by the executive officer will depend on the extent to which the awards vest and the price of our common stock at the time of exercise or vesting.

Arrangements with Named Executive Officers

Employment Agreements. On April 5, 2004 we entered into an employment agreement with Michael R. Minogue in connection with his employment as our President and Chief Executive Officer. In the employment agreement, we agreed to employ Mr. Minogue as our President and Chief Executive Officer, reporting to the Board of Directors. The agreement initially provided for an annual salary of $325,000 for the fiscal year ended March 31, 2005, and a target bonus for such fiscal year of up to $325,000. Mr. Minogue’s employment agreement also provides that our Compensation Committee will review Mr. Minogue’s salary and target bonus on an annual basis. On May 23, 2008, Mr. Minogue’s salary and target bonus were increased to $371,700. All salary is payable in semi-monthly installments in accordance with our practice. In addition, pursuant to the employment agreement, Mr. Minogue was granted options to purchase 400,000 shares of our common stock. The agreement also provides for, among other things, certain vacation, life insurance and other benefits to Mr. Minogue. The employment agreement has an indefinite term, and is terminable by either party by notice to the other.

On December 15, 2008, Robert L. Bowen accepted our offer letter to become our Chief Financial Officer. The offer letter provides that Mr. Bowen will receive an annual salary of $290,000 and sets his target annual bonus at $150,000 for outstanding performance. This target bonus was pro-rated for the remainder of fiscal 2009. On April 17, 2009, our Compensation Committee agreed to amend the change of control agreement with Mr. Bowen, to extend this benefit to a period from eighteen months to two years. As provided in the offer letter, our Compensation Committee has also granted Mr. Bowen a stock option to purchase 100,000 shares of our common stock. The stock option vests 25% annually over four years and has an exercise price equal to the closing price of our common stock on December 22, 2008.

On April 10, 2007, Dr. David M. Weber accepted our offer letter to become our Chief Operating Officer. The offer letter provided that Dr. Weber would receive a starting salary of $250,000 per year and a signing bonus of $12,000. On May 28, 2009, Dr. Weber’s salary was increased to $275,000. In addition, Dr. Weber is eligible for an annual bonus with a target pay-out of $100,000. The offer letter provided for the grant to Dr. Weber of a stock option to purchase 130,000 shares of our common stock on the date his employment started, vesting annually over four years.

Each of our other named executive officers has entered into our standard employment agreements, which contain customary provisions relating to the handling of proprietary information and assignment of inventions, as well as restrictions on competition and solicitation during the period of employment and for two years after termination. In addition, the agreements provide that we may terminate the employee with or without cause, but in the case of a termination without cause more than six months after the date employment begins, we are required to provide 28-days’ prior notice.

Change of Control Agreement. We entered into a change of control agreement with Mr. Minogue when he began employment with us in April 2004. The agreement was entered into in order to provide Mr. Minogue with a sense of job security and the ability to focus on his work without needing to worry about losing his job upon a change of control. The agreement specifically provides that, following a change of control, we will continue to employ Mr. Minogue for twenty-four full months in the same or a similar position at a base annual salary equal to at least twelve times the highest monthly base salary received within the last twelve months prior to the change of control and an annual bonus equal to his average bonus over the last three years. In addition, Mr. Minogue agreed to remain our employee for six full months following a change of control. Upon a change of control, and if Mr. Minogue is still employed at the end of this six-month period, all unvested stock options and stock appreciation rights held by him will become vested. Mr. Minogue can terminate his employment for good reason, and we may terminate his employment for cause. The agreement provides for certain payments to be made to Mr. Minogue or his family upon certain circumstances following a change of control, including upon his death, disability, termination of employment by us without cause, and termination of employment by him for good reason. In the event that Mr. Minogue is obligated to pay any excise taxes, including interest and penalties, under Section 4999 of the Internal Revenue Code of 1986, as amended, Mr. Minogue will be entitled to receive a

“gross-up” payment such that he will receive an after-tax amount sufficient to enable him to pay all such excises taxes, interest and penalties. The agreement also provides for a continuation of certain benefits provided to Mr. Minogue before the change of control on terms at least as favorable to Mr. Minogue as in effect before the change of control. These payments and benefits are described in more detail below. In December 2008 we amended the change of control agreement to make certain changes related to compliance with Section 409A of the Internal Revenue Code.

On August 13, 2008 the Compensation Committee also authorized us to enter into change of control agreements with Messrs. Bolt, Greenfield and Weber. Under the change of control agreements, if we terminate an Executive’s employment for any reason other than for cause, death or disability during the two-year period following a change of control, as defined in the change of control agreements, or if an Executive terminates his employment with us for good reason during the eighteen-month period beginning six months after a change of control, then we are required to make a lump sum payment to that Executive equal to two times the sum of the Executive’s then-effective annual salary plus their target bonus. For up to two years following any such termination, we are also required to provide medical and dental benefits to the Executive and his family. Additionally upon such a termination, the vesting of all of the Executive’s then-unvested and outstanding stock options and restricted stock will accelerate.

At the time of his hiring, we entered into a similar change of control agreement with Robert L. Bowen, except that it provided for one and a half times his then-effective annual salary plus target bonus. On April 17, 2009, our Compensation Committee agreed to amend the change of control agreement with Mr. Bowen, to provide for two times his then-effective annual salary plus target bonus.

On October 1, 2008, we mutually agreed that our former chief financial officer, Daniel J. Sutherby, would resign his position. In connection with Mr. Sutherby’s resignation, on October 10, 2008 we entered into a separation and release agreement with Mr. Sutherby, pursuant to which we agreed to continue his salary and benefits for six months and Mr. Sutherby agreed to be available to us during this time period, to assist us in the transitioning of his duties. We also extended the period in which Mr. Sutherby can exercise his vested stock options until September 30, 2009.

Estimated Potential Payments Following a Change of Control

The following table provides information regarding the estimated amounts payable to the individuals named below upon the occurrence of the triggering events described below, in each case assuming that a change of control had occurred on March 31, 2009, the last day of our last fiscal year. The amounts shown as payable upon the triggering events described below do not include amounts earned by the individual and accrued before the occurrence of the triggering event but payable after the triggering event, such as accrued and unpaid salary or the value of accrued but unused vacation days.

(1)

Represents only the estimated value of the acceleration of the vesting of stock options held by the executive, assuming a stock price of $4.90, which was the closing market price of our common stock on March 31, 2009. This value is based on the difference between such price and the exercise price of the accelerated options. Because the exercise price of all stock options held by our named executive officers as of March 31, 2009 is in excess of this closing price, no value has been attributed to the acceleration of outstanding stock options. All stock options and stock appreciation rights held by the named executive officers accelerate in full if the executive is terminated following a change of control other than for cause or good reason. In addition, in the case of Mr. Minogue, all stock options and stock appreciation rights accelerate in full if following a change of control his employment continues for at least six months.

(2)	Represents only the estimated value of the acceleration of restricted stock held by the executives, assuming a stock price of $4.90, which was the closing market price of our common stock on March 31, 2009.

(3)

Represents the estimated gross-up payment owed to the executives based on the assumptions in this table. Mr. Minogue is entitled to a full gross-up payment to the extent that any excise tax is imposed by Section 4999 of the Internal Revenue Code. The other named executive officers are entitled to a gross-up payment to the extent that any excise tax is imposed by Section 4999 of the Internal Revenue Code, but subject to other limitations on the amount of the excise tax.

(4)	This row does not reflect the value of continued compensation for services rendered during the course of employment.

(5)

Assumes that termination occurs on March 31, 2009. Termination later in the year would also entitle the executive to a pro rata portion of his bonus, based on the number of days lapsed during the year prior to termination. Bonus amounts and severance payments are payable in a lump sum. Benefits continuation consists of the continuation of medical benefits for the executive and his family, which, as of March 31, 2009, are payable over a period of 18 months in the case of Messrs. Minogue and Bowen and over 24 months for the other named executive officers. Other perquisites and personal benefits are excluded because the estimated aggregate amount of such benefits is less than $10,000 for each executive officer.

AUDIT COMMITTEE REPORT

The Board of Directors appointed an Audit Committee to review the Company’s consolidated financial statements and financial reporting procedures, the adequacy and effectiveness of its accounting and financial controls and the independence and performance of its independent registered public accounting firm. The Audit Committee also selects our independent registered public accounting firm. The Audit Committee is governed by a written charter adopted by the Board of Directors. A copy of our audit committee charter is available through the “Our Company—Corporate Governance” section of our website, located at www.abiomed.com.

The Audit Committee currently consists of three non-employee directors. Each member of the Audit Committee is “independent” within the meaning of the marketplace rules of the Nasdaq Stock Market.

The Company’s management is responsible for the financial reporting process, including the system of internal controls, and for the preparation of consolidated financial statements in accordance with generally accepted accounting principles. The Company’s independent auditors are responsible for auditing those financial statements. Our responsibility is to monitor and review these processes. However, we are not professionally engaged in the practice of accounting or auditing and are not experts in the fields of accounting or auditing, including with respect to auditor independence. We have relied, without independent verification, on the information provided to us and on the representations made by the Company’s management and independent auditors.

In fulfilling our responsibilities as the Audit Committee, we conferred with Deloitte & Touche LLP, the Company’s independent registered public accounting firm for the fiscal year ended March 31, 2009, regarding the overall scope and plans for Deloitte & Touche LLP’s audit of the Company’s financial statements for the fiscal year ended March 31, 2009. We met with them, with and without the Company’s management present, to discuss the results of their audit and their evaluation of the Company’s internal controls and the overall quality of the Company’s financial reporting. We reviewed and discussed the audited consolidated financial statements for fiscal 2009 with management and the independent auditors.

In addition, during the course of fiscal 2009 and thereafter before filing the Company’s Annual Report on Form 10-K for fiscal 2009, our management completed the documentation, testing and evaluation of the Company’s internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. We were kept apprised of the progress of the evaluation and provided oversight to management during the process. In connection with this oversight, we received periodic updates provided by management and Deloitte & Touche LLP at each scheduled Audit Committee meeting to review our progress. At the conclusion of the process, management provided us with, and we reviewed, a report on the effectiveness of the Company’s internal control over financial reporting. We also reviewed the report of management contained in the Company’s Annual Report on Form 10-K for fiscal 2009 filed with the SEC, as well as Deloitte & Touche LLP’s Report of Independent Registered Public Accounting Firm included in the Company’s Annual Report on Form 10-K related to its audit of (i) the consolidated financial statements, and (ii) the effectiveness of internal control over financial reporting.

We reviewed the Company’s audited financial statements with management and Deloitte & Touche LLP. We discussed with Deloitte & Touche LLP the matters required to be discussed by Statement of Auditing Standards No. 61, including a discussion of its judgments as to the quality, not just the acceptability, of the Company’s reporting mechanisms and such other matters as are required to be discussed with the Audit Committee in accordance with the standards of the Public Company Accounting Oversight Board (United States). In addition, we received from Deloitte & Touche LLP the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board and discussed these documents with Deloitte & Touche LLP, as well as other matters related to Deloitte & Touche LLP’s independence from management and the Company.

Based on the reviews and discussions referred to above, and subject to the limitations on our role and responsibilities referred to above and in the Audit Committee Charter, we recommended to the Board of Directors that the Company’s audited financial statements be included in its Annual Report on Form 10-K for fiscal 2009 for filing with the Securities and Exchange Commission.

Audit fees also include fees paid by us to Deloitte & Touche LLP in connection with their annual audit of our internal control over financial reporting, statutory audits, consents and other services related to interaction with the SEC with respect to accounting matters and consultations related to implementation of accounting standards.

Audit-related fees. Audit-related fees include fees paid by us to Deloitte & Touche LLP that principally cover assurance and related services that are traditionally performed by our independent registered public accounting firm.

Tax fees. Tax fees cover services performed by the tax personnel of Deloitte & Touche LLP except those services specifically related to the audit of our financial statements, and include fees for tax compliance, tax planning and advice.

All other fees. No fees were paid to Deloitte & Touche LLP that were not audit or tax-related.

Our Audit Committee has determined that the services Deloitte & Touche LLP performed for us during fiscal 2009 were at all times compatible with its independence.

Policy on Pre-Approval of Audit and Non-Audit Services

Our Audit Committee has the sole authority to approve the scope of the audit and any audit or permitted non-audit services as well as all audit fees and terms. Our Audit Committee must pre-approve any audit and permitted non-audit services by our independent registered public accounting firm. Our Audit Committee will not approve the engagement of our independent registered public accounting firm to perform any services that our independent registered public accounting firm would be prohibited from providing under applicable securities laws or the rules of the Nasdaq Stock Market. In assessing whether to approve the use of our independent registered public accounting firm for permitted non-audit services, our Audit Committee tries to minimize relationships that could appear to impair the objectivity of our independent registered public accounting firm. Our Audit Committee has delegated pre-approval authority for non-audit services to the Chair of our Audit Committee within the guidelines discussed above. The Chair is required to inform our Audit Committee of each decision at the next regularly scheduled Audit Committee meeting following the decision to permit our independent registered public accounting firm to perform non-audit services.

Bowen on December 22, 2008 was not timely filed.

The Board may establish an additional single-member committee (consisting of an executive officer) that shall have the power and authority to grant Awards to non-executive officers and to make all other determinations under the Plan with respect thereto.

(b) Powers of Committee. The Committee shall have the power and authority to grant and modify Awards consistent with the terms of the Plan, including the power and authority:

(i) to select the persons to whom Awards may from time to time be granted;

(ii) to determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Non-Statutory Stock Options, Restricted Stock, Unrestricted Stock, Performance Shares and Stock Appreciation Rights, or any combination of the foregoing, granted to any one or more participants;

(iii) to determine the number of shares to be covered by any Award;

(iv) to determine and modify the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, which terms and conditions may differ among individual Awards and participants, and to approve the form of written instruments evidencing the Awards and to approve any agreements modifying the terms and conditions of any Awards; provided, however, that no such action shall adversely affect rights under any outstanding Award without the participant’s consent;

(v) to accelerate the exercisability or vesting of all or any portion of any Award;

(vi) to extend the period in which any outstanding Stock Option or Stock Appreciation Right may be exercised; and

(vii) to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan.

All decisions and interpretations of the Committee shall be binding on all persons, including the Company and Plan participants. No member or former member of the Committee or the Board shall be liable for any action or determination made in good faith with respect to this Plan.

SECTION 4. Shares Issuable under the Plan; Mergers; Substitution.

(a) Shares Issuable. The maximum number of shares of Stock which may be issued in respect of Awards (including Stock Appreciation Rights) granted under the Plan, subject to adjustment upon changes in capitalization of the Company as provided in this Section 4, shall be 3,800,000 shares; provided, however, that as of the date the Plan is approved by stockholders of the Company, such maximum number of shares issuable shall be increased by any shares of Stock available for future awards under the Company’s 2000 Stock Incentive Plan, 1998 Equity Incentive Plan or 1989 Non-Qualified Stock Option Plan for Non-Employee Directors (collectively, the “Current Plans”) as of such date. For purposes of this limitation, the shares of Stock underlying any Awards which are forfeited, cancelled, reacquired by the Company or otherwise terminated (other than by exercise), whether under the Plan or under the Current Plans, shall be added back to the shares of Stock with respect to which Awards may be granted under the Plan; provided, however, that shares of Stock used to pay the exercise

A-3

price of a Stock Option pursuant to Section 6(d)(i)(ii) or (iii), or to pay withholding taxes with respect to an Award pursuant to Section 12(b), (or shares of Stock used to pay the exercise price of any award or to pay withholding taxes under corresponding provisions of any of the Current Plans), and shares of Stock subject to Stock Appreciation Rights (whether under the Plan or under any of the Current Plans) that are not issued upon the exercise of such Stock Appreciation Right, shall not be added back to the shares of Stock with respect to which Awards may be granted; and provided further any increase in the number of shares as a result of forfeiture, cancellation or reacquisition by the Company of shares pursuant to awards under the Current Plans shall not exceed 4,500,000 shares of Stock (subject to adjustment as provided in Section 4(c) below). Shares issued under the Plan may be authorized but unissued shares or shares reacquired by the Company. Solely for the purpose of applying the limitation on the maximum number of shares issuable as set forth in this Section 4(a) (and not for purposes of Section 4(b) below), any shares of Stock that are subject to Options or Stock Appreciation Rights shall be counted against this limit by one share of Stock for every one share of Stock subject to a grant, and any shares of Stock that are subject to Awards other than Options or Stock Appreciation Rights shall be counted against this limit as 1.5 shares of Stock for every one share of Stock subject to a grant. As of the date the Plan is approved by stockholders of the Company, no additional awards shall be permitted to be granted from the Current Plans and all unexpired awards granted from the Current Plans shall continue in full force and operation except as they may be exercised, be terminated or lapse, by their own terms and conditions.

(b) Limitation on Awards. In no event may any Plan participant be granted Awards (including Stock Appreciation Rights) with respect to more than 300,000 shares of Stock in any calendar year. The number of shares of Stock relating to an Award granted to a Plan participant in a calendar year that is subsequently forfeited, cancelled or otherwise terminated shall continue to count toward the foregoing limitation in such calendar year. In addition, if the exercise price of an Award is subsequently reduced, the transaction shall be deemed a cancellation of the original Award and the grant of a new one so that both transactions shall count toward the maximum shares issuable in the calendar year of each respective transaction.

(c) Stock Dividends, Mergers, etc. In the event that after the effective date of the Plan, the Company effects a stock dividend, stock split or similar change in capitalization affecting the Stock, the Committee shall make appropriate adjustments in (i) the number and kind of shares of stock or securities with respect to which Awards may thereafter be granted (including without limitation the limitations set forth in Sections 4(a) and (b) above), (ii) the number and kind of shares remaining subject to outstanding Awards, and (iii) the exercise or purchase price in respect of such shares. In the event of any merger, consolidation, dissolution or liquidation of the Company, the Committee in its sole discretion may, as to any outstanding Awards, make such substitution or adjustment in the aggregate number of shares reserved for issuance under the Plan and in the number and purchase price (if any) of shares subject to such Awards as it may determine and as may be permitted by the terms of such transaction, or accelerate, amend or terminate such Awards upon such terms and conditions as it shall provide (which, in the case of the termination of the vested portion of any Award, shall require payment or other consideration which the Committee deems equitable in the circumstances), subject, however, to the provisions of Section 16.

(d) Substitute Awards. The Committee may grant Awards under the Plan in substitution for stock and stock based awards held by employees of another corporation who concurrently become employees of the Company or an Affiliate as the result of a merger or consolidation of the employing corporation with the Company or an Affiliate or the acquisition by the Company or an Affiliate of property or stock of the employing corporation. The Committee may direct that the substitute awards be granted on such terms and conditions as the Committee considers appropriate in the circumstances.

A-4

SECTION 5. Eligibility.

Awards may be granted to officers, directors and employees of, and consultants and advisers to, the Company or its Affiliates (“Eligible Persons”).

SECTION 6. Stock Options.

The Committee may grant Stock Options to Eligible Persons. Any Stock Option granted under the Plan shall be in such form as the Committee may from time to time approve. Stock Options granted under the Plan may be either Incentive Stock Options (subject to compliance with applicable law) or Non-Statutory Stock Options. Unless otherwise so designated, an Option shall be a Non-Statutory Stock Option. To the extent that any Option does not qualify as an Incentive Stock Option, it shall constitute a Non-Statutory Stock Option. No Incentive Stock Option shall be granted under the Plan after the tenth anniversary of the date of adoption of the Plan by the Board. The Committee in its discretion may determine the effective date of Stock Options, provided, however, that grants of Incentive Stock Options shall be made only to persons who are, on the effective date of the grant, employees of the Company or an Affiliate. Stock Options granted pursuant to this Section 6 shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee shall deem desirable.

(a) Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 6 shall be determined by the Committee at the time of grant but shall be not less than one hundred percent (100%) of Fair Market Value on the date of grant. If an employee owns or is deemed to own (by reason of the attribution rules applicable under Section 424(d) of the Code) more than ten percent (10%) of the combined voting power of all classes of stock of the Company or any subsidiary or parent corporation and an Incentive Stock Option is granted to such employee, the exercise price shall be not less than one hundred ten percent (110%) of Fair Market Value on the date of grant.

(b) Option Term. The term of each Stock Option shall be fixed by the Committee, but no Stock Option shall be exercisable more than ten (10) years after the date the Stock Option is granted. If an employee owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than ten percent (10%) of the combined voting power of all classes of stock of the Company or any subsidiary or parent corporation and an Incentive Stock Option is granted to such employee, the term of such Incentive Stock Option shall be no more than five (5) years from the date of grant.

(c) Exercisability; Rights of a Stockholder. Stock Options shall become vested and exercisable at such time or times, whether or not in installments, as shall be determined by the Committee. The Committee may at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options.

(d) Method of Exercise. Stock Options may be exercised in whole or in part, by delivering written notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by delivery of cash or bank check or other instrument acceptable to the Committee in an amount equal to the exercise price of such Options, or, to the extent provided in the applicable agreement setting forth the terms and conditions of such Option, by one or more of the following methods:

(i) by delivery to the Company of shares of Stock of the Company having a fair market value equal in amount to the aggregate exercise price of the Options being exercised and not subject to restriction under any Company incentive plan; or

(ii) if the class of Stock is registered under the Exchange Act at such time, by delivery to the Company of a properly executed exercise notice along with irrevocable instructions to a broker to deliver promptly to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event that the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall

A-5

comply with such procedures and enter into such agreements of indemnity and other agreements as the Committee shall prescribe as a condition of such payment procedure (including, in the case of an optionee who is an executive officer of the Company, such procedures and agreements as the Committee deems appropriate in order to avoid any extension of credit in the form of a personal loan to such officer). The Company need not act upon such exercise notice until the Company receives full payment of the exercise price; or

(iii) by reducing the number of Option shares otherwise issuable to the optionee upon exercise of the Option by a number of shares of Common Stock having a fair market value equal to such aggregate exercise price of the Options being exercised; or

(iv) by any combination of such methods of payment.

The delivery of certificates representing shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the Optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Stock Option or imposed by applicable law.

(e) Non-transferability of Options. Except as the Committee may provide with respect to a Non-Statutory Stock Option, no Stock Option shall be transferable other than by will or by the laws of descent and distribution and all Stock Options shall be exercisable, during the optionee’s lifetime, only by the optionee.

(f) Annual Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its Affiliates become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000.

SECTION 7. Restricted Stock Awards.

(a) Nature of Restricted Stock Award. The Committee in its discretion may grant Restricted Stock Awards to any Eligible Person, entitling the recipient to acquire, for such purchase price, if any, as may be determined by the Committee, shares of Stock subject to such restrictions and conditions as the Committee may determine at the time of grant (“Restricted Stock”), including continued employment and/or achievement of pre-established performance goals and objectives.

(b) Acceptance of Award. A participant who is granted a Restricted Stock Award shall have no rights with respect to such Award unless the participant shall have accepted the Award within sixty (60) days (or such shorter date as the Committee may specify) following the award date by making payment to the Company of the specified purchase price, if any, of the shares covered by the Award and by executing and delivering to the Company a written instrument that sets forth the terms and conditions applicable to the Restricted Stock in such form as the Committee shall determine.

(c) Rights as a Stockholder. Upon complying with Section 7(b) above, a participant shall have all the rights of a stockholder with respect to the Restricted Stock, including voting and dividend rights, subject to non-transferability restrictions and Company repurchase or forfeiture rights described in this Section 7 and subject to such other conditions contained in the written instrument evidencing the Restricted Award. Unless the Committee shall otherwise determine, certificates evidencing shares of Restricted Stock Award shall remain in the possession of the Company until such shares are vested as provided in Section 7(e) below.

(d) Restrictions. Shares of Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein. In the event of termination of employment by the Company and its Affiliates for any reason (including death, Disability, Normal Retirement and for Cause), any shares of Restricted Stock which have not then vested shall automatically be forfeited to the Company.

A-6

(e) Vesting of Restricted Stock. The Committee at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock and the Company’s right of forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Stock and shall be deemed “vested.” The Committee at any time may accelerate such date or dates and otherwise waive or, subject to Section 14, amend any conditions of the Award.

(f) Waiver, Deferral and Reinvestment of Dividends. The written instrument evidencing the Restricted Stock Award may require or permit the immediate payment, waiver, deferral or investment of dividends paid on the Restricted Stock.

SECTION 8. Unrestricted Stock Awards.

(a) Grant or Sale of Unrestricted Stock. The Committee in its discretion may grant or sell to any Eligible Person shares of Stock free of any restrictions under the Plan (“Unrestricted Stock”) at a purchase price determined by the Committee. Shares of Unrestricted Stock may be granted or sold as described in the preceding sentence in respect of past services or other valid consideration.

(b) Restrictions on Transfers. The right to receive unrestricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered, other than by will or the laws of descent and distribution.

SECTION 9. Performance Share Awards.

A Performance Share Award is an award entitling the recipient to acquire shares of Stock upon the attainment of specified performance goals. The Committee may make Performance Share Awards independent of or in connection with the granting of any other Award under the Plan. Performance Share Awards may be granted under the Plan to any Eligible Person. The Committee in its discretion shall determine whether and to whom Performance Share Awards shall be made, the performance goals applicable under each such Award (which may include, without limitation, continued employment by the recipient or a specified achievement by the recipient, the Company or any business unit of the Company), the periods during which performance is to be measured, and all other limitations and conditions applicable to the Award or the Stock issuable thereunder. Upon the attainment of the specified performance goal shares of Stock shall be issued pursuant to the Performance Share Award as soon as practicable thereafter, but in no event later than two and one-half months after the calendar year in which such performance goal is attained.

SECTION 10. Stock Appreciation Rights.

The Committee in its discretion may grant Stock Appreciation Rights to any Eligible Person. A Stock Appreciation Right shall entitle the participant upon exercise thereof to receive from the Company, upon written request to the Company at its principal offices (the “Request”), a number of shares of Stock having an aggregate Fair Market Value equal to the product of (a) the excess of Fair Market Value, on the date of such Request, over the exercise price per share of Stock specified in such Stock Appreciation Right (which exercise price shall be not less than one hundred percent (100%) of Fair Market Value on the date of grant), multiplied by (b) the number of shares of Stock for which such Stock Appreciation Right shall be exercised. The term of each Stock Appreciation Right shall be fixed by the Committee, but no Stock Appreciation Right shall be exercisable more than ten (10) years after the date the Stock Appreciation Right is granted.

A-7

SECTION 11. Termination of Stock Options and Stock Appreciation Rights.

(a) Incentive Stock Options:

(i) Termination by Death. If any participant’s employment by the Company and its Affiliates terminates by reason of death, any Incentive Stock Option owned by such participant may thereafter be exercised to the extent exercisable at the date of death, by the legal representative or legatee of the participant, for a period of one hundred eighty (180) days from the date of death, or until the expiration of the stated term of the Incentive Stock Option, if earlier.

(ii) Termination by Reason of Disability or Normal Retirement.

(A) Any Incentive Stock Option held by a participant whose employment by the Company and its Affiliates has terminated by reason of Disability may thereafter be exercised, to the extent it was exercisable at the time of such termination, for a period of ninety (90) days from the date of such termination of employment, or until the expiration of the stated term of the Incentive Stock Option, if earlier.

(B) Any Incentive Stock Option held by a participant whose employment by the Company and its Affiliates has terminated by reason of Normal Retirement may thereafter be exercised, to the extent it was exercisable at the time of such termination, for a period of ninety (90) days from the date of such termination of employment, or until the expiration of the stated term of the Incentive Stock Option, if earlier.

(C) The Committee shall have sole authority and discretion to determine whether a participant’s employment has been terminated by reason of Disability or Normal Retirement.

(iii) Termination for Cause. If any participant’s employment by the Company and its Affiliates has been terminated for Cause, as determined by the Committee in its sole discretion, any Incentive Stock Option held by such participant shall immediately terminate and be of no further force and effect.

(iv) Other Termination. Unless otherwise determined by the Committee, if a participant’s employment by the Company and its Affiliates terminates for any reason other than death, Disability, Normal Retirement or for Cause, any Incentive Stock Option held by such participant may thereafter be exercised, to the extent it was exercisable on the date of termination of employment, for thirty (30) days from the date of termination of employment or until the expiration of the stated term of the Incentive Stock Option, if earlier.

(b) Non-Statutory Stock Options and Stock Appreciation Rights. Any Non-Statutory Stock Option or Stock Appreciation Right granted under the Plan shall contain such terms and conditions with respect to its termination as the Committee, in its discretion, may from time to time determine.

SECTION 12. Tax Withholding and Notice.

(a) Payment by Participant. Each participant shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the participant for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the Committee regarding payment of any Federal, state, local and/or payroll taxes of any kind required by law to be withheld with respect to such income. The Company and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the participant.

(b) Payment in Shares. A Participant may elect, with the consent of the Committee, to have such tax withholding obligation satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Stock to be issued pursuant to an Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due with respect to such Award, or (ii) delivering to the Company a number of shares of Stock with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due. For purposes of Section 4 hereof, shares of stock that are withheld by or delivered to the Company pursuant to this Section 12 shall not be added back to the shares of Stock with respect to which Awards may be granted under the Plan.

A-8

(c) Notice of Disqualifying Disposition. Each holder of an Incentive Stock Option shall agree to notify the Company in writing immediately after making a disqualifying disposition (as defined in Section 421(b) of the Code) of any Stock purchased upon exercise of an Incentive Stock Option.

SECTION 13. Transfer and Leave of Absence.

For purposes of the Plan, the following events shall not be deemed a termination of employment:

(a) a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another;

(b) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Committee otherwise so provides in writing; provided, that the vesting date or dates of any unvested Award held by such employee shall automatically be extended by a period of time equal to the period of such approved leave of absence.

SECTION 14. Amendments and Termination.

The Board may at any time amend or discontinue the Plan and the Committee may at any time amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder’s consent. Notwithstanding the foregoing, neither the Board nor the Committee shall have the power or authority to decrease the exercise price of any outstanding Stock Option or Stock Appreciation Right, whether through amendment, cancellation and regrant, exchange or any other means, except for changes made pursuant to Section 4(c).

This Plan shall terminate as of the tenth anniversary of its effective date. The Board may terminate this Plan at any earlier time for any reason. No Award may be granted after the Plan has been terminated. No Award granted while this Plan is in effect shall be adversely altered or impaired by termination of this Plan, except with the consent of the holder of such Award. The power of the Committee to construe and interpret this Plan and the Awards granted prior to the termination of this Plan shall continue after such termination.

SECTION 15. Status of Plan.

With respect to the portion of any Award which has not been exercised and any payments in cash, Stock or other consideration not received by a participant, a participant shall have no rights greater than those of a general creditor of the Company unless the Committee shall otherwise expressly determine in connection with any Award or Awards.

SECTION 16. Change of Control Provisions.

(a) Upon the occurrence of a Change of Control as defined in this Section 16:

(i) subject to the provisions of clause (iii) below, after the effective date of such Change of Control, each holder of an outstanding Stock Option, Restricted Stock Award, Performance Share Award or Stock Appreciation Right shall be entitled, upon exercise of such Award, to receive, in lieu of shares of Stock (or consideration based upon the Fair Market Value of Stock), shares of such stock or other securities, cash or property (or consideration based upon shares of such stock or other securities, cash or property) as the holders of shares of Stock received in connection with the Change of Control;

(ii) the Committee may accelerate, fully or in part, the time for exercise of, and waive any or all conditions and restrictions on, each unexercised and unexpired Stock Option, Restricted Stock Award, Performance Share Award and Stock Appreciation Right, effective upon a date prior or subsequent to the effective date of such Change of Control, as specified by the Committee; or

A-9

(iii) each outstanding Stock Option, Restricted Stock Award, Performance Share Award and Stock Appreciation Right may be cancelled by the Committee as of the effective date of any such Change of Control provided that (x) prior written notice of such cancellation shall be given to each holder of such an Award and (y) the Committee shall have accelerated the time for exercise of all such unexercised and unexpired Awards and each holder of such an Award shall have the right to exercise such Award, during the ten (10) day period preceding the effective date of such Change of Control.

(b) “Change of Control” shall mean the occurrence of any one of the following events:

(i) any “person” (as such term is used in Sections 13(d) and 14(d)(2) of the Exchange Act) becomes, after the Effective Date of this Plan, a “beneficial owner” (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) (other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company, or any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the combined voting power of the Company’s then outstanding securities; or

(ii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation or other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or

(iii) the stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets.

SECTION 17. General Provisions.

(a) No Distribution; Compliance with Legal Requirements. The Committee may require each person acquiring shares pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof.

No shares of Stock shall be issued pursuant to an Award until all applicable securities laws and other legal and stock exchange requirements have been satisfied. The Committee may require the placing of such stop orders, with respect to and restrictive legends on, certificates for Stock and Awards as it deems appropriate.

(b) Delivery of Stock Certificates. Delivery of stock certificates to participants under this Plan shall be deemed effected for all purposes when the Company or a stock transfer agent of the Company shall have delivered such certificates in the United States mail, addressed to the participant, at the participant’s last known address on file with the Company.

(c) Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of the Plan or grant of any Award under the Plan does not confer upon any employee any right to continued employment with the Company or any Affiliate.

(d) Lock-Up Agreement. By accepting any Award, the recipient shall be deemed to have agreed that, if so requested by the Company or by the underwriters managing any offering of securities of the Company that is the subject of a registration statement filed under the United States Securities Act of 1933, as amended from time to time (the “Act”), the recipient will not, without the prior written consent of the Company or such underwriters, as the case may be, sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any shares subject to any such Award during the Lock-up Period, as defined below. The “Lock-Up Period” shall

A-10

mean a period of time not to exceed 180 days, plus such additional number of days (not to exceed 35) as may reasonably be requested to enable the underwriter(s) of such offering to comply with Rule 2711(f) of the Financial Industry Regulatory Authority or any amendment or successor thereto from the effective date of the registration statement under the Act for such offering, or, if greater, such number of days as shall have been agreed to by each director and executive officer of the Company in connection with such offering in a substantially similar lock-up agreement by which each such director and executive officer is bound. If requested by the Company or such underwriters, the recipient shall enter into an agreement with such underwriters consistent with the foregoing.

SECTION 18. Effective Date of Plan.

This Plan shall become effective upon its adoption by the Company’s Board of Directors. If the Plan shall not be approved by the stockholders of the Company within twelve months following its adoption, this Plan shall terminate and be of no further force or effect.

SECTION 19. Governing Law.

This Plan shall be governed by, and construed and enforced in accordance with, the substantive laws of The Commonwealth of Massachusetts, without regard to its principles of conflicts of laws.
