     Whereas EMPLOYEE has been employed by the Company; and

     Whereas, EMPLOYEE is party to a certain agreement, entitled “INVENTION, NON-DISCLOSURE AND NON-SOLICITATION AGREEMENT” (the “Proprietary Information Agreement); and

     Whereas, EMPLOYEE’s employment with the Company will terminate as of September 26, 2008.

     Now, therefore, in consideration of the foregoing and the mutual covenants contained herein, the parties agree as follows:

Such payment shall be subject to applicable taxes, which shall remain the responsibility of the applicable party. If EMPLOYEE is entitled to commission payments, the Company shall also pay to EMPLOYEE such commissions as are due to EMPLOYEE under the most recent compensation plan provided to said EMPLOYEE prior to discharge.

If EMPLOYEE accepts employment elsewhere, either in the form of full-time employment or consultancy, prior to the September 26, 2008 date, we will terminate employment immediately and commence severance payments, assuming employment does not violate EMPLOYEE’s non-compete obligations.

In addition, if EMPLOYEE has upheld the obligations and covenants set forth in this document, on or about February 28, 2009, ATG will pay a 2008 bonus, prorated to the termination date and according to the criteria of EMPLOYEE’S individual plan, the financial results of the year and the terms and conditions of the annual bonus plan.

     After this date, EMPLOYEE’S participation in the benefit plans will be through COBRA. ATG will cover COBRA costs during the severance period of 12 weeks. After that time, if EMPLOYEE wishes to continue COBRA, he will be responsible for all premiums due. Please be aware that the amount that ATG pays toward your COBRA premiums is considered taxable wages.

3. The Company will further reimburse EMPLOYEE for any valid and approved expenses incurred as the result of EMPLOYEES job responsibilities with Company subject to any required offset by the Company. Expenses should be submitted within 2 weeks of EMPLOYEE’s last day worked.

4. Vesting in EMPLOYEE’s stock options shall cease as of September 26, 2008, or the Termination Date.

5. (a) Except as expressly otherwise provided herein (including without limitation any breach after the Effective Date of the agreements set forth in paragraph 6) and except for any claims which arise because of breach of this Agreement by the Company, EMPLOYEE hereby waives, releases and promises never to assert any and all claims that he has or might have against the Company and its subsidiaries, officers, directors, stockholders, affiliates, agents, attorneys, employees, successors or assigns, arising from or related to his/her employment with Company, the termination of such employment or, if applicable, his/her status as an officer or stockholder of the Company or any of its subsidiaries. The foregoing release as it applies to officers, directors and other individuals is intended to release such persons in all capacities, including individual and official. The released claims include, but are not limited to, claims arising under federal, state, and local statutory law, such as the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, Title VII of the Civil Rights Act of 1964 and the law of contract and tort.

6. Each party agrees not to make any statements that are professionally or personally disparaging about or adverse to, the interests of the other party (including, in the Company’s case, the Company’s officers, directors and managers), including, but not limited to, any statements that disparage any such person, product, service, finances, financial condition, internal operations, customer satisfaction, new business implementation, capability or any other aspect of the business of the Company, and that each party will not engage in any conduct which is intended to harm professionally or personally the reputation of the other party.

7. This Agreement shall be governed by the laws of the Commonwealth of Massachusetts, without regard to its choice of law provisions. No amendment or waiver of this Agreement or any of its provision shall be binding upon the party against whom the enforcement of such amendment or waiver is sought unless it is made in writing and signed by or on behalf of such party. The waiver by either party of a breach of any provision of this Agreement by the other party shall not operate as a waiver by that party of any subsequent breach of the same or any other provision of this Agreement by the other party. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors and administrators, successors and assigns, except that it may not be assigned by EMPLOYEE.
