Exhibit A

Form of Release

1. For and in consideration of the severance payments and other benefits provided in the Employment Agreement, effective as of the Effective Date (the “Employment Agreement”), by and between Alterix Inc., a Delaware corporation (“Alterix”) and me, and other good and valuable consideration, I, for and on behalf of myself and my heirs, administrators, executors, and assigns, effective the date hereof, do hereby fully and forever release, remise and discharge Alterix, any predecessor or successor entity, its successors and assigns, and the direct and indirect parents, subsidiaries, affiliates of Alterix, together with their respective officers, directors, partners, shareholders, members, managers, employees and agents (collectively, the “Group”), from any and all Claims (as defined below) which I had, may have had, or now have against Alterix and/or any other member of the Group, for or by reason of any matter, cause or thing whatsoever, including any claim arising out of or attributable to my employment or the termination of my employment with Alterix, including but not limited to Claims of breach of contract, wrongful termination, unjust dismissal, defamation, libel or slander, or under any federal, state or local law dealing with discrimination based on age, race, sex, national origin, handicap, religion, disability or sexual preference. This release of Claims includes, but is not limited to, all Claims arising under Title VII of the Civil Rights Act, the Americans with Disabilities Act, the Civil Rights Act of 1991, the Family Medical Leave Act, the Equal Pay Act, Massachusetts General Laws, Chapter 151B, the Massachusetts Wage Act, and any and all applicable federal statutes and regulations, and any and all applicable statutes, regulations and common law of the Commonwealth of Massachusetts, and any and all other federal, state, and local laws, statutes, regulations, and common law, and any other purported restriction on an employer’s right to terminate the employment of employees. As used in this Release, the term “Claims” shall include all claims, covenants, warranties, promises, undertakings, actions, suits, causes of action, obligations, debts, attorneys’ fees, accounts, judgments, losses and liabilities, of whatsoever kind or nature, in law, equity or otherwise.

2. I specifically release all Claims under the Age Discrimination in Employment Act (the “ADEA”) relating to my employment and its termination.

3. I represent that I have not filed or permitted to be filed against the Group, individually or collectively, any lawsuits and I covenant and agree that I will not do so at any time hereafter with respect to the subject matter of this Release and Claims released pursuant to this Release (including, without limitation, any Claims relating to the termination of my employment), except as may be necessary to enforce this Release, to obtain benefits described in or granted under this Release, or to seek a determination of the validity of the waiver of my rights under the ADEA. Except as otherwise provided in the preceding sentence, I will not voluntarily participate in any judicial proceeding of any nature or description against any member of the Group that in any way involves the allegations and facts that I could have raised against any member of the Group as of the date hereof.

4. I am specifically agreeing to the terms of this Release because Alterix has agreed to pay to me money and other benefits to which I am not otherwise entitled under Alterix’s policies, and has provided such other good and valuable consideration as specified herein. Alterix has

Exhibit A – Page 1

agreed to provide this money and other benefits because of my agreement to accept it in full settlement of all possible Claims I might have or ever had, and because of my execution of this Release.

6. Upon termination of my employment, I agree to return to Alterix all Alterix property, including without limitation, proprietary information, reports, files, memoranda, records, computer hardware, software, credit cards, door and file keys, computer access codes or disks and instructional manuals, and other physical or personal property which I received or prepared or helped prepare in connection with my employment with Alterix, and that I will not retain any copies, duplicates, reproductions or excerpts thereof.

7. I acknowledge that I have read this Release in its entirety, fully understand its meaning and am executing this Release voluntarily and of my own free will with full knowledge of its significance. I acknowledge and warrant that I have had the opportunity to consider for twenty-one (21) days the terms and provisions of this Release and that I have been advised by Alterix to consult with an attorney prior to executing this Release. I shall have the right to revoke this Release for a period of seven (7) days following my execution of this Release, by giving written notice of such revocation to Alterix. This Release shall not become effective until the eighth day following my execution of it (the “Release Effective Date”).

8. I agree to maintain the confidentiality of this Release, and to refrain from disclosing or making reference to its terms except as required by law or with my accountant or attorney.

9. I agree that I shall not make, or cause to be made, any statement or communicate any information (whether oral or written) that disparages or reflects negatively on Alterix or any member of the Group.

10. Alterix shall be entitled to have the provisions of this Release specifically enforced through injunctive relief, without having to prove the inadequacy of the available remedies at law, and without being required to post bond or security, it being acknowledged and agreed that such breach will cause irreparable injury to Alterix and that money damages will not provide an adequate remedy to Alterix. In addition, in the event that I breach any of the provisions of this Release (and in addition to any other legal or equitable remedies Alterix may have), Alterix shall be entitled to cease making any of the payments or providing any of the benefits referred to in paragraph 1 above, recover any payments referred to in paragraph 1 previously paid to me, and recover as permitted by applicable law the reasonable costs and attorneys’ fees incurred in seeking relief for any such breach. Moreover, I understand and agree that if I breach any provisions of this Release, in addition to any other legal or equitable remedy Alterix may have, I shall reimburse Alterix for all its reasonable attorneys’ fees and costs incurred by it arising out of any such breach. The remedies set forth in this paragraph shall not apply to any challenge to the validity of the waiver and release of my rights under the ADEA. In the event I challenge the validity of the waiver and release of my rights under the ADEA, then Alterix’s right to attorneys’ fees and costs shall be governed by the provisions of the ADEA, so that Alterix may recover such fees and costs if the lawsuit is brought by me in bad faith. Any such action permitted to Alterix by this paragraph, however, shall not affect or impair any of my obligations under this Release, including without limitation, the release of claims in paragraph 1 hereof. I further agree that nothing herein shall preclude Alterix from recovering attorneys’ fees, costs or any other remedies specifically authorized under applicable law.

Exhibit A – Page 2

11. In the event that any one or more of the provisions of this Release is held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby. Moreover, if any one or more of the provisions contained in this Release is held to be excessively broad as to duration, scope, activity or subject, such provisions will be construed by limiting and reducing them so as to be enforceable to the maximum extent compatible with applicable law.

12. Nothing herein shall be deemed to constitute an admission of wrongdoing by Alterix or any member of the Group. Neither this Release nor any of its terms shall be used as an admission or introduced as evidence as to any issue of law or fact in any proceeding, suit or action, other than an action to enforce this Release.

13. The terms of this Release and all rights and obligations of the parties thereto, including its enforcement, shall be interpreted and governed by the laws of the Commonwealth of Massachusetts, without regard to the choice of law provisions of Massachusetts law, to the extent such provisions require the application of the laws of any other jurisdiction.
