Plan.


 


1.            Vesting, Exercisability and Termination.


 


(a)          No portion of this Stock Option may be exercised until such portion shall have vested and become exercisable.


 


(b)          Except as set forth below, and subject to the determination of the Committee in its sole discretion to accelerate the vesting
schedule hereunder, this Stock Option shall be vested and exercisable on the respective dates indicated below:


 


(i)             This Stock Option shall initially be unvested and unexercisable.


 


(ii)            This Stock Option shall vest and become exercisable in accordance with the Vesting Schedule set forth in the Grant Notice.


 


(c)          Termination. Except as may otherwise be provided by the Committee, if the Optionee’s Service Relationship is terminated,
the period within which to exercise this Stock Option will be subject to earlier termination as set forth below (and if not exercised
within such period, shall thereafter terminate subject, in each case, to Section 3(c) of the Plan):


 


(i)             Termination Due to Death or Disability. If the Optionee’s Service Relationship terminates by reason of such Optionee’s

termination, for a period of 90 days from the date of termination or until the Expiration Date, if earlier; provided however,
if the Optionee’s Service Relationship is terminated for Cause, this Stock Option shall terminate immediately upon the date

		2.	Exercise
                                         of Stock Option.

(a)          Equitable Relief. The parties hereto agree and declare that legal remedies may be inadequate to enforce the provisions
of this Agreement and that equitable relief, including specific performance and injunctive relief, may be used to enforce the

the restrictions contained in this Agreement shall apply with equal force to additional and/or substitute securities, if any,
received by the Optionee in exchange for, or by virtue of his or her ownership of, this Stock Option or Shares acquired pursuant
thereto.


 


(c)          Change and Modifications. This Agreement may not be orally changed, modified or terminated, nor shall any oral waiver of
any of its terms be effective. This Agreement may be changed, modified or terminated only by an agreement in writing signed by
the Company and the Optionee.

State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance

of any law other than the law of the State of Massachusetts.


 


(e)          Headings. The headings are intended only for convenience in finding the subject matter and do not constitute part of the
text of this Agreement and shall not be considered in the interpretation of this Agreement.


 


(f)           Saving Clause. If any provision(s) of this Agreement shall be determined to be illegal or unenforceable, such determination
shall in no manner affect the legality or enforceability of any other provision hereof.

other address or addresses as may have been furnished by such party in writing to the other.


 


(h)          Benefit and Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto,
their respective successors, assigns, and legal representatives. The Company has the right to assign this Agreement, and such

    5 


     


    



(i)           Counterparts. For the convenience of the parties and to facilitate execution, this Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same document.


 


(j)           Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and
supersedes all prior agreements and discussions between the parties concerning such subject matter.


 


		7.	Dispute
                                         Resolution.



 


(a)          Except as provided below, any dispute arising out of or relating to the Plan or this Stock Option, this Agreement, or the breach,
termination or validity of the Plan, this Stock Option or this Agreement, shall be finally settled by binding arbitration conducted
expeditiously in accordance with the J.A.M.S./Endispute Comprehensive Arbitration Rules and Procedures (the “J.A.M.S. Rules”).
The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16, and judgment upon the award rendered
by the arbitrators may be entered by any court having jurisdiction thereof. The place of arbitration shall be Boston, Massachusetts.


 


(b)          The arbitration shall commence within 60 days of the date on which a written demand for arbitration is filed by any party hereto.
In connection with the arbitration proceeding, the arbitrator shall have the power to order the production of documents by each
party and any third-party witnesses. In addition, each party may take up to three depositions as of right, and the arbitrator
may in his or her discretion allow additional depositions upon good cause shown by the moving party. However, the arbitrator shall
not have the power to order the answering of interrogatories or the response to requests for admission. In connection with any
arbitration, each party to the arbitration shall provide to the other, no later than seven business days before the date of the
arbitration, the identity of all persons that may testify at the arbitration and a copy of all documents that may be introduced
at the arbitration or considered or used by a party’s witness or expert. The arbitrator’s decision and award shall
be made and delivered within six months of the selection of the arbitrator. The arbitrator’s decision shall set forth a
reasoned basis for any award of damages or finding of liability. The arbitrator shall not have power to award damages in excess
of actual compensatory damages and shall not multiply actual damages or award punitive damages, and each party hereby irrevocably
waives any claim to such damages.


 


(c)          The Company, the Optionee, each party to the Agreement and any other holder of Shares issued pursuant to this Agreement (each,
a “Party”) covenants and agrees that such party will participate in the arbitration in good faith. This Section 7
applies equally to requests for temporary, preliminary or permanent injunctive relief, except that in the case of temporary or
preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding immediate
and irreparable harm.





    6 


     


    



(d)          Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District Court of competent jurisdiction for
the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives, and agrees not to assert, by way of
motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the
jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution (except as protected
by applicable law), that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action
or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii)
hereby waives and agrees not to seek any review by any court of any other jurisdiction which may be called upon to grant an enforcement
of the judgment of any such court. Each Party hereby consents to service of process by registered mail at the address to which
notices are to be given. Each Party agrees that its, his or her submission to jurisdiction and its, his or her consent to service
of process by mail is made for the express benefit of each other Party. Final judgment against any Party in any such action, suit
or proceeding may be enforced in other jurisdictions by suit, action or proceeding on the judgment, or in any other manner provided
by or pursuant to the laws of such other jurisdiction.


 


8.           Waiver of Statutory Information Rights. The Optionee understands and agrees that, but for the waiver made herein, the Optionee
would be entitled, upon written demand under oath stating the purpose thereof, to inspect for any proper purpose, and to make
copies and extracts from, the Company’s stock ledger, a list of its stockholders, and its other books and records, and the
books and records of subsidiaries of the Company, if any, under the circumstances and in the manner provided in Section 220 of
the General Corporation Law of Delaware (any and all such rights, and any and all such other rights of the Optionee as may be
provided for in Section 220, the “Inspection Rights”). In light of the foregoing, until the first sale of Stock of
the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and
Exchange Commission under the Securities Act, the Optionee hereby unconditionally and irrevocably waives the Inspection Rights,
whether such Inspection Rights would be exercised or pursued directly or indirectly pursuant to Section 220 or otherwise, and
covenants and agrees never to directly or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause
to be commenced any claim, action, cause of action, or other proceeding to pursue or exercise the Inspection Rights. The foregoing
waiver shall not affect any rights of a director, in his or her capacity as such, under Section 220. The foregoing waiver shall
not apply to any contractual inspection rights of the Optionee under any other written agreement between the Optionee and the
Company.
