Each party hereby irrevocably consents and agrees to arbitrate any Covered Claims through binding arbitration, and forever waives and gives up its right to have a judge or jury decide any Covered Claims.

Each party agrees that it will notify the other in writing of any claim it may have within fifteen (15) calendar days after it becomes aware of such claim so that the parties can attempt in good faith to resolve such claim informally. Such notice must include a detailed description of the nature or basis of the claim, and the specific relief that such party is seeking. If the parties cannot agree how to resolve the claim within fifteen (15) calendar days after the recipient’s receipt of the claim notice, then either party may commence an arbitration proceeding. The parties irrevocably consent and agree that (a) any arbitration will occur in the Commonwealth of Massachusetts, (b) arbitration will be conducted confidentially by a single arbitrator in accordance with the then-current arbitration rules and procedures of the American Arbitration Association (“AAA”) (and its then-existing emergency relief procedures to the extent either party seeks emergency relief prior to the appointment of an arbitrator), which rules and procedures are available at www.adr.org, unless those rules or procedures conflict with any express term of this Agreement, in which case this Agreement shall control, and (c) the federal courts sitting in the Commonwealth of Massachusetts have exclusive jurisdiction over any appeals and the enforcement of an arbitration award.

As limited by the Federal Arbitration Act, this Agreement and applicable AAA rules, the arbitrator will have (a) the exclusive authority and jurisdiction to make all procedural and substantive decisions regarding a Covered Claim, and (b) the authority to grant any

The rules of AAA and additional information about AAA are available on the AAA website. By agreeing to be bound by this Agreement, Executive either (i) acknowledges and agrees that he has read and understands the AAA rules; or (ii) waives his opportunity to read the AAA rules and any claim that the AAA rules are unfair or should not apply for any reason.

Each party will pay such party’s own attorneys’ fees, witness fees and all other costs and fees that such party incurs in connection with the arbitration, except that each of the Company and the Executive will pay one-half (1/2) of all AAA filing or administrative fees. The arbitrator will not otherwise have authority to award any attorneys’ fees, witness fees or other costs and fees unless a statute or contract at issue in the dispute authorizes the award of such costs and fees to the applicable prevailing party, in which case the arbitrator shall have the authority to make an award of such costs and fees to the full extent permitted by applicable law. If there is a dispute as to who is the prevailing party, the arbitrator will decide such issue.

Excluded Claims. The “Excluded Claims” shall be any workers’ compensation claims, unemployment compensation benefits, claims for benefits under a plan that is governed by Employee Retirement Income Security Act of 1974, claims that are subject to the exclusive jurisdiction of the National Labor Relations Board, and any claim that is expressly precluded from inclusion in this arbitration provision by a governing federal statute.

To the extent that the foregoing does not apply, the Executive hereby irrevocably assigns to the Company, for no additional consideration, the Executive’s entire right, title, and interest in and to all Work Product and Intellectual Property Rights therein, including the right to sue, counterclaim, and recover for all past, present, and future infringement, misappropriation, or dilution thereof, and all rights corresponding thereto throughout the world. Nothing contained in this Agreement shall be construed to reduce or limit the Company’s rights, title, or interest in any Work Product or Intellectual Property Rights so as to be less in any respect than that the Company would have had in the absence of this Agreement.

Further Assurances; Power of Attorney. During and after his employment by the Company, the Executive agrees to reasonably cooperate with the Company to (a) apply for, obtain, perfect, and transfer to the Company the Work Product as well as any and all Intellectual Property Rights in the Work Product in any jurisdiction in the world, and (b) maintain, protect and enforce the same, including, without limitation, giving testimony and executing and delivering to the Company any and all applications, oaths, declarations, affidavits, waivers, assignments, and other documents and instruments as shall be requested by the Company. The Executive hereby irrevocably grants the Company power of attorney to execute and deliver any such documents on the Executive’s behalf in his name and to do all other lawfully permitted acts to transfer the Work Product to the Company and further the transfer, prosecution, issuance, and maintenance of all Intellectual Property Rights therein, to the full extent permitted by law, if the Executive does not promptly cooperate with the Company’s request (without limiting the rights the Company shall have in such circumstances by operation of law).

The parties mutually agree that the Agreement can be specifically enforced in court and can be cited as evidence in legal proceedings alleging breach of the Agreement.

Modification and Waiver. No provision of this Agreement may be amended or modified unless such amendment or modification is agreed to in writing and signed by the Executive and by a member of the Board (other than Executive) with the Board’s prior approval. No waiver by either of the parties of any breach by the other party hereto of any condition or provision of this Agreement to be performed by the other party hereto shall be deemed a waiver of any similar or dissimilar provision or condition at the same or any prior or subsequent time, nor shall the failure of or delay by either of the parties in exercising any right, power, or privilege hereunder operate as a waiver thereof to preclude any other or further exercise thereof or the exercise of any other such right, power, or privilege.

Severability.

Counterparts. This Agreement may be executed in separate counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

Section 409A.

General Compliance. This Agreement is intended to comply with Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”) or an exemption thereunder and shall be construed and administered in accordance with Section 409A. Notwithstanding any other provision of this Agreement, payments provided under this Agreement may only be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments under this Agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this Agreement shall be treated as a separate payment. Any payments to be made under this Agreement upon a termination of employment shall only be made upon a “separation from service” under Section 409A. Notwithstanding any provision of this Agreement to the contrary, in no event shall the timing of the Executive’s execution of the Release, directly or indirectly, result in the Executive designating the calendar year of payment of any amounts of deferred compensation subject to Section 409A and if a payment that is subject to execution of the Release could be made in more than one taxable year, payment shall be made in the later taxable year. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under this Agreement comply with Section 409A, and in no event shall the Company be liable for all or any portion of any taxes, penalties, interest, or other expenses that may be incurred by the Executive on account of non-compliance with Section 409A.

Specified Employees. Notwithstanding any other provision of this Agreement, if any payment or benefit provided to the Executive in connection with his termination of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and the Executive is determined to be a “specified employee” as defined in Section 409A(a)(2)(b)(i), then such payment or benefit shall not be paid until the first payroll date to occur following the six-month anniversary of the Termination Date or, if earlier, on the Executive’s death (the “Specified Employee Payment Date”). The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date and interest on such amounts calculated based on the applicable federal rate published by the Internal Revenue Service for the month in which the Executive’s separation from service occurs shall be paid to the Executive in a lump sum on the Specified Employee Payment Date and thereafter, any remaining payments shall be paid without delay in accordance with their original schedule.

Reimbursements. To the extent required by Section 409A, each reimbursement or in-kind benefit provided under this Agreement shall be provided in accordance with the following:

the amount of expenses eligible for reimbursement, or in-kind benefits provided, during each calendar year cannot affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year;

any reimbursement of an eligible expense shall be paid to the Executive on or before the last day of the calendar year following the calendar year in which the expense was incurred; and

any right to reimbursements or in-kind benefits under this Agreement shall not be subject to liquidation or exchange for another benefit.

Tax Gross-ups. Any tax gross-up payments provided under this Agreement shall be paid to the Executive on or before December 31 of the calendar year immediately following the calendar year in which the Executive remits the related taxes.

Successors and Assigns. This Agreement is personal to the Executive and shall not be assigned by the Executive. Any purported assignment by the Executive shall be null and void from the initial date of the purported assignment. The Company may assign this Agreement to any successor or assign (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business or assets of the Company. This Agreement shall inure to the benefit of the Company and its successors and assigns.

Notices and all other communications provided for in this Agreement shall be in writing and shall be delivered personally or sent by registered or certified mail, return receipt requested, or by overnight carrier to the parties at the addresses set forth below (or such other addresses as specified by the parties by like notice): If to the Company: One Kendall Square, 1400 West, Suite 14303, Cambridge, MA 02139; If to the Executive: Robert Connelly, 127 Bay State Road, Apartment 5, Boston, MA 02215.

Representations of the Executive. The Executive represents and warrants to the Company that:

Withholding. The Company shall have the right to withhold from any amount payable hereunder any Federal, state, and local taxes in order for the Company to satisfy any withholding tax obligation it may have under any applicable law or regulation.

Survival. Upon the expiration or other termination of this Agreement, the respective rights and obligations of the parties hereto shall survive such expiration or other termination to the extent necessary to carry out the intentions of the parties under this Agreement.

THE EXECUTIVE ACKNOWLEDGES AND AGREES THAT HE HAS HAD AN OPPORTUNITY TO ASK QUESTIONS AND THE RIGHT CONSULT WITH AN ATTORNEY OF HIS CHOICE BEFORE SIGNING THIS AGREEMENT.
