5.01 Grant of Option. On an Enrollment Date of each Offering Period, each Participant shall be deemed to have been granted an option to purchase on the Exercise Date of the Offering Period a number of shares of Common Stock determined by dividing the Participant's accumulated payroll deductions/contributions as of the Exercise Date by the Purchase Price.

The applicable Purchase Price shall be an amount equal to the lower of (a) eighty-five percent (85%) of the Fair Market Value of a share of Common Stock on the Enrollment Date or (b) eighty-five percent (85%) of the Fair Market Value of a share of Common Stock on the Exercise Date; provided, however, that the Purchase Price may be adjusted by the Administrator pursuant to Article VIII.

5.03 Limitation. Except as provided below or otherwise provided by the Administrator, the maximum number of shares of Common Stock that a Participant may purchase with respect to any Offering Period is the number of shares determined by dividing $12,500 by the Fair Market Value of a share of Common Stock on the Enrollment Date. Notwithstanding the preceding sentence, the maximum number of shares of Common Stock that a Participant may purchase with respect to the First Offering

Period shall be the number of shares determined by dividing $25,000 by the Fair Market Value of a share of Common Stock on the Enrollment Date for First Offering Period.

5.04 Option Exercise. Except as provided in Section 4.07, a Participant's option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to an option will be purchased for such Participant at the applicable Purchase Price with the accumulated payroll deductions/contributions in the Participant's account. During a Participant's lifetime, the Participant's option to purchase shares hereunder is exercisable only by him or her.

5.06 Purchase Reductions. Notwithstanding anything herein to the contrary, the Administrator shall have the discretion to reduce the number of shares of Common Stock to be purchased by Participants with respect to an Offering Period and to allocate such reduced number of shares among Participants in such Offering Period, so long as such reduction and allocation is done in a manner consistent with Code Section 423. Any payroll deductions not applied to the purchase of shares of Common Stock shall be promptly refunded to Participants after the Exercise Date of the Offering Period to which such reduction applies.

5.07 Delivery. After each Exercise Date on which a purchase of shares of Common Stock occurs, shares purchased upon exercise of the Participant's option shall be held in such Participant's account. As soon as administratively practicable after the Participant's request, the Company will distribute to such Participant, as appropriate, the shares in each Participant's account in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant's account.

Subject to Section 9.05, the maximum number of shares of Common Stock that will be made available for sale under the Restated Plan will be 400,000 shares of Common Stock, plus an annual increase, if any, to be added on the first day of each Fiscal Year so that the total number of shares of Common Stock available shall be equal to the greater of (i) the number of shares of Common Stock available under the Plan as of the last day of the immediately preceding Fiscal Year and

(ii) the lesser of (A) 400,000 shares of Common Stock and (B) seventy-five hundredths of one percent (0.75%) of the outstanding shares of Common Stock on the last day of the immediately preceding Fiscal Year. Any or all shares of Common Stock may be granted under the Code Section 423(b) Component.

procedures that it deems necessary for administration of the Plan (including, without limitation, to adopt such rules, procedures and sub-plans as are necessary or appropriate to accommodate the specific requirements of applicable local laws to permit the participation in the Plan by Employees who are foreign nationals or employed outside of the United States). Every finding, decision and determination made by the Administrator shall, to the fullest extent permitted by law, be final and binding upon all parties.

Such committee may select one of its members as its chairperson, shall hold meetings at such times and places as it shall deem advisable, and may hold telephonic meetings. All determinations of the committee shall be made by a majority of its members. A decision or determination reduced to writing and signed by a majority of the members of the committee shall be fully effective as if it had been made by a majority vote at a meeting duly called and held. The committee may appoint a secretary and shall make such rules and regulations for the conduct of its business as it shall deem advisable.

8.01 Amendment or Termination. The Board may at any time and for any reason suspend, terminate or amend the Plan; provided, however, that the Board shall not, without the approval of the stockholders of the Company, alter (a) the aggregate number of shares of Common Stock that may be issued under the Plan (except pursuant to Section 9.05), or (b) the class of Employees eligible to receive options under the Plan, other than to designate Participating Companies; and provided, further, that, subject to Section 8.02, no termination, modification, or amendment of the Plan may, without the consent of an Employee then having an option under the Plan to purchase shares of Common Stock, adversely affect the rights of such Employee under such option.

9.02 Use of Funds. The Company may use all payroll deductions/contributions received or held by the Company under the Plan for any corporate purpose, and the Company will not be obligated to segregate such payroll deductions/contributions, unless otherwise required by applicable local law.

9.03 Reports. Individual accounts will be maintained for each Participant. Statements of account will be given to Participants at least annually, which statements will set forth the amounts of payroll deductions/contributions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any.

In addition, if permitted by the Administrator in its sole discretion, a Participant may designate a beneficiary who is to receive any cash from the Participant's account under the Plan in the event of such Participant's death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent may be required by the Administrator in its sole discretion for such designation to be effective, unless otherwise required by applicable local law.

(b) If the Administrator in its sole discretion has permitted the Participant to make a beneficiary designation, the Participant may change such designation of beneficiary at any time by written notice. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant's death, the Company will deliver such shares and/or cash to the Participant's spouse, if any, and if none, to the Participant's estate.

Action by the Administrator may include adjustment of: (i) the number and class of Common Stock that may be delivered under the Plan, (ii) the Purchase Price per share, (iii) the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and (iv) the numerical limits of Section 6.01.

The Administrator will notify each Participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant's option has been changed to the New Exercise Date and that the Participant's option will be exercised automatically on the New Exercise Date.

9.06 Notices.

9.07 Conditions Upon Issuance of Shares.

(a) Shares of Common Stock will not be issued with respect to an option under the Plan unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, including the rules and regulations promulgated thereunder, the Exchange Act, and the requirements of any stock exchange upon which the shares may then be listed, and will further be subject to the approval of counsel for the Company with respect to such compliance. If, on the Exercise Date of any Offering Period, as delayed to the maximum extent permissible, the shares of Common Stock have not yet been issued, all payroll deductions/contributions accumulated during the Offering Period (reduced to the extent, if any, such deductions/contributions have been used to acquire shares of Common Stock) shall be distributed to Participants, without interest, unless otherwise required under applicable local law.

(b) As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

9.08 Covenants of the Company. The Company shall seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of Common stock upon exercise. If, after commercially

reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell shares of Common Stock upon exercise unless and until such authority is obtained.

9.09 Effective Date. The Restated Plan shall become effective as of its adoption by the Board, subject to approval by the holders of a majority of the shares of Common Stock, and shall continue in effect until the earlier of the date that (a) the shares of Common Stock reserved for issuance have been depleted, and (b) the Restated Plan is terminated under Article VIII.

9.10 No Employment Rights. The Plan does not, directly or indirectly, create in any person any right with respect to employment or continuation of employment by the Company or any Related Company, and it shall not be deemed to interfere in any way with the Company's or any Related Company's right to terminate, or otherwise modify, any Employee's employment at any time.

9.12 Electronic Delivery of Plan Information and Electronic Signatures. To the extent permitted by applicable law, the Company may deliver by email or other electronic means (including posting on a web site maintained by the Company or by a third party under contract with the Company) all documents relating to the Plan (including without limitation, prospectuses required by applicable securities law) and all other documents that the Company is required to deliver to its security holders (including without limitation, annual reports and proxy statements).

9.13 Treatment of Non-U.S. Participants. Participants who are paid in foreign currency, and who contribute foreign currency to the Plan through contributions or payroll deductions will have such contributions converted to U.S. dollars. The exchange rate and method for such conversion will be determined as prescribed by the Administrator.

Without amending the Plan, the Administrator may grant options or establish other procedures to provide benefits to Employees who are not U.S. Employees on such terms and conditions different from those specified in the Plan as may, in the judgment of the Administrator, be necessary or desirable to foster and promote achievement of the purposes of the Plan and shall have the authority to adopt such modifications, procedures, subplans and the like as may be necessary or desirable (a) to comply with provisions of the laws or regulations or conform to the requirements to operate the Plan in a qualified or tax or accounting advantageous manner in other countries or jurisdictions in which the Company or any Participating Company may operate or have employees, (b) to ensure the viability of the benefits from the Plan to Employees employed in such countries or jurisdictions and (c) to meet the objectives of the Plan.

9.15 Governing Law. Except to the extent superseded by the federal laws of the United States, the law of the State of Delaware, without regard to its conflict of laws provisions, will govern all matters relating to the Plan. Participants, the Company, a Participating Company, a Subsidiary, the Parent, and any Affiliate each submit and consent to the jurisdiction of the courts in the Commonwealth of Massachusetts, County of Worcester, including the Federal Courts located therein, should Federal jurisdiction requirements exist in any dispute or action brought to enforce (or otherwise relating to) the Plan.
