(b)           Method of Exercise.  The Option shall be exercisable by written notice to the Company which shall state the election to exercise the Option, the number of shares for which the Option is being exercised, and such other representations and agreements as to the Optionee’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement.  Such written notice shall be signed by the Optionee and shall be delivered to the Company’s Stock Administration Department, or other authorized representative of the Company, prior to the termination of the Option as set forth in Section 6, accompanied by full payment of the option price for the number of shares being purchased.

(c)           Form of Payment of Option Price.  Such payment shall be made (1) in cash, by check, or cash equivalent, (2) by tender of shares of the Company’s stock owned by the Optionee and having a fair market value not less than the option price, which (i) either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly from the Company, and (ii) have a fair market value not less than the option price, (3) Immediate Sales Proceeds, as defined below, or (4) by any combination of the foregoing.  Notwithstanding the foregoing, the Option may not be exercised by the tender of the Company’s stock to the extent such tender of stock would constitute a violation of the provisions of any law, regulation, and/or agreement restricting the redemption of the Company’s stock.  “Immediate Sales Proceeds” shall mean the assignment in form acceptable to the Company of the proceeds of a sale of the shares acquired on the exercise of the Option pursuant to a procedure approved by the Company.  The Company reserves the right to decline to approve any such procedure in the Company’s sole and absolute discretion.

(e)           Certificate Registration.  The shares as to which the Option shall be exercised shall be registered in the name of the Optionee, or, if applicable, the heirs of the Optionee.  If payment of the option price is accomplished using Immediate Sales Proceeds, the certificate or certificates shall be registered in the name of a nominee which is an authorized broker for the Company’s same-day sale program.

(f)            Restriction on Grant of Option and Issuance of Shares.  The grant of the Option and the issuance of shares pursuant to the Option shall be subject to compliance with all applicable requirements of federal or state law with respect to such securities.  The Option may not be exercised if the issuance of shares upon such exercise would constitute a violation of any applicable federal or state securities laws or other law or regulations.  In addition, no Option may be exercised unless (i) a registration statement under the Securities Act of 1933, as amended, shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option, or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of said Act.  As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

(g)           Fractional Shares.  The Company shall not be required to issue fractional shares upon the exercise of the Option.

5.             Non-Transferability of the Option.  The Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of the Optionee only by the Optionee.

6.             Termination of the Option.  The Option shall terminate and may no longer be exercised on the first to occur of (i) the Option Termination Date as defined above, (ii) the last date for exercising the Option following termination of the Optionee’s relationship as a Service Provider as described in Section 7, (iii) upon a Transfer of Control as described in Section 8, or (iv) upon a vote by the shareholders of the Company to disapprove the reservation of shares required for issuance hereunder.

7.             Termination of Service Relationship:

(a)           Termination of Option.  If the Optionee ceases to be a Service Provider for any reason except by reason of death or Disability, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee ceased to be a Service Provider, may be exercised by the Optionee within three (3) months after the date on which the Optionee’s relationship as a Service Provider terminates, but in any event no later than the Option Termination Date.  If the Optionee’s Service Provider relationship is terminated because of the

death of the Optionee or Disability of the Optionee, the Option may be exercised by the Optionee (or the Optionee’s legal representative) at any time prior to the expiration of twelve (12) months from the date of such termination, but in any event no later than the Option Termination Date. The Optionee’s Service Provider relationship shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee’s termination the Service Provider relationship.

(b)           Exercise Prevented by Law.  Except as provided in this Section 7, the Option shall terminate and may not be exercised after the Optionee’s Service Provider relationship terminates unless the exercise of the Option in accordance with this Section 7 is prevented by the provisions of Section 4(f). If the exercise of the Option is so prevented, the Option shall remain exercisable until three (3) months after the date the Optionee is notified by the Company or its Parent or Subsidiary for whom the Optionee provides service that the Option is exercisable but in no event later than the Option Termination Date.

(c)           Leave of Absence.  For purposes hereof, the Optionee’s employment with a Participating Company shall not be deemed to terminate if the Optionee takes any military leave, sick leave or other bona fide leave of absence approved by the Company of ninety (90) days or less.  In the event of a leave in excess of ninety (90) days, the Optionee’s employment shall be deemed to terminate on the ninety-first (91st) day of the leave unless the Optionee’s right to reemployment with the Participating Company remains guaranteed by statute or contract.

(d)           No Guarantee of Continued Service.  OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

8.             Ownership Change and Transfer of Control.  For the purposes hereof the “Control Company” shall mean the Participating Company whose stock is subject to this Option.  Except as provided in an applicable Executive Severance Plan, Management Retention Agreement or other formal written employment contract between the Optionee and the Company, in the event of a Transfer of Control, the Board, in its sole discretion, shall either (i) provide that any unexercised portion of the Option shall be fully exercisable and fully vested as of a date prior to the Transfer of Control, as the Board so determines, or (ii) arrange with the surviving, continuing, successor, or purchasing corporation, as the case may be, that such corporation assume the Company’s right and obligations under this Option Agreement either by assuming the Option or by granting an equivalent substituted option by the successor corporation or a Parent or Subsidiary of the successor corporation. The Option shall terminate as of the date of the Transfer of Control to the extent that the Option is neither exercised as of the date of the Transfer of Control, nor assumed by the surviving continuing, successor or purchasing corporation, as the case may be.  Subject to the terms and conditions of the Plan, in the event that there is a  conflict

between this Option Agreement and any applicable, (i) Executive Severance Plan, (ii) formal written management retention agreement, or (iii) formal written employment agreement; the applicable severance plan, management retention agreement or employment agreement shall govern.

9.             Effect of Change in Stock Subject to the Option.  Appropriate adjustments shall be made in the number, exercise price and class of shares of stock subject to the Option in the event of a stock dividend, stock split, reverse stock split, combination, reclassification or like change in the capital structure of the Company.  In the event a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change) shares of another corporation (the “New Shares”), the Company may unilaterally amend the Option to provide that the Option is exercisable for New Shares.  In the event of any such amendment, the number of shares and the exercise price shall be adjusted in a fair and equitable manner.

10.           Rights as a Shareholder or Employee.  The Optionee shall have no rights as a shareholder with respect to any shares covered by the Option until the date of the issuance of a certificate or certificates for the shares for which the Option has been exercised.  No adjustment shall be made for dividends or distributions or other rights for which the record date is prior to the date such stock certificate or certificates are issued, except as provided in Section 9.  Nothing in the Option shall confer upon the Optionee any right to continue in the service of a Participating Company or interfere in any way with any right of the Participating Company to terminate the Optionee’s Service Provider relationship at any time.

11.           Legends.  The Company may at any time place legends referencing any applicable federal and/or state securities restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement.  The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to this Option in the possession of the Optionee in order to effectuate the provisions of this Section.

12.           Binding Effect.  This Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns.

13.           Amendment or Termination.  The Administrator may at any time amend or terminate the Plan and/or the Option; provided, however, that no such amendment or termination may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee.

14.           Integrated Agreement.  The Plan is incorporated herein by reference.  The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee.  To the extent contemplated herein, the provisions of this Option Agreement shall survive any exercise of this Option and shall remain in full force and effect.

15.           Applicable Law.  This Option Agreement shall be construed in accordance with, and all disputes hereunder shall be governed by, the laws of the Commonwealth of Massachusetts without regard to its conflict of laws rules.  The parties hereby irrevocably consent and submit to the personal jurisdiction and venue of the United States District Court for the District of Massachusetts (sitting in Boston, Massachusetts) or the Suffolk County Superior Court (sitting in Boston, Massachusetts) for any

16.           Data Privacy.  By entering into this Option Agreement, and as a condition of the grant of the Option, the Optionee consents to the collection, use and transfer of personal data as described in this Section.
