Employee’s employment with API shall end on the Separation Date. Employee agrees that as a

condition of this Agreement, Employee will not seek reemployment with API at any time and should Employee apply in the future, his application for employment will not be considered by API and will be null and void.

Employee also acknowledges that API shall make such filings with the United States Securities and Exchange Commission with respect to Employee’s resignation and this Agreement as required by law and as it deems appropriate.

3. Severance Payment and Other Consideration. API, in consideration for the promises contained herein, agrees as follows:

(a) API will continue to pay Employee’s weekly salary of two thousand four hundred three and 85/100 ($2403.85) (less withholdings and deductions required by law) for fifty-two (52) weekly pay periods (the “Severance Period”), payable to Employee via direct deposit on API’s regular paydays. Such payments shall begin within 14 days after the Effective Date. The payments due to Employee pursuant to this Section 3(a) cannot be offset by amounts due from Employee to API pursuant to any cause of action or claim, except as set forth in Section 9(d) and 10(h).

Moreover, the parties understand and agree that any tax consequences and/or liability arising from the payment to Employee shall be the sole responsibility of Employee. To this extent, Employee acknowledges and agrees that he will pay any and all federal, state and local income tax which may be determined to be due in connection with the payments described in this Section 3. Employee also agrees to indemnify API from all tax and/or other liability (including, but not limited to, fines, penalties, interest, and costs) arising from or relating to the payment described in this Section 3 and/or imposed by the Internal Revenue Service, the State of New York, or any other taxing agency or tribunal as a result of API’s failure to withhold taxes on the payments described in this Section 3 or any portion thereof.

Employee further understands that prior to the Disclosure Date confidentiality is a material and critical aspect of this Agreement and is of paramount concern to all involved. Until the Disclosure Date, Employee agrees as follows. Employee agrees to keep the terms of this Agreement confidential and will not disclose any information concerning it to anyone except his spouse, tax advisor, legal counsel, or anyone required by law to know the contents of the Agreement; provided, that Employee shall inform any of these specified persons that Employee is bound by a confidentiality covenant and prior to any such disclosure to any of such persons, require that such person agree to abide by the terms of such covenant and not disclose any information concerning the Agreement.

(b) By signing this Agreement, Employee agrees that he has not disclosed or used information in violation of this provision and that he will not do so in the future.

Employee certifies and declares that he already has returned or shall return to the custody of API all Proprietary Information, company property (including without limitation any laptop computer, cellular telephone, and Blackberry or similar devices) and Company Documents - as well as any copies of Proprietary Information, company property, and Company Documents - in his possession by the Separation Date.

any employee of API to terminate such employment. For purposes of the Agreement, “Employee” means current employee as well as anyone employed by API within the six (6) month period prior to the Separation Date; provided, that this provision shall not preclude Employee or any business in which Employee may engage or participate from soliciting any such employee by means of or hiring any such employee who responds to a public announcement placed by the business as long as Employee otherwise complies with the provisions of the Section 10(e).

(g) Employee will not directly or indirectly seek to cause any person or organization to discontinue or limit its or their current relationship with API.

(h) Employee hereby agrees and declares that he, his agents, and anyone else he has told have not and will not violate any of the conditions of this Section 10. Employee understands that a violation of this Section 10 would cause irreparable harm to API in an amount incapable of precise determination. Accordingly, Employee agrees that in the event he, his agent, or anyone he has told violates this Section 10 or any portion thereof, prior to the time Employee receives all of the payments set forth in Section 3 that are due to him, Employee will forfeit any right to any further payments. API shall be entitled to both temporary and permanent injunctive relief, without regard to any requirement for the posting of a bond or any other security by API in connection therewith, in addition to any other form of legal and equitable relief provided for in this Agreement or otherwise appropriate.

13. Applicable Law. This Agreement shall be interpreted, enforced, and governed under the laws of the State of New York.

14. Future Assistance. In partial exchange for the severance package, Employee agrees that he will cooperate and make himself reasonably available to current API personnel in the event Employee’s assistance is needed to locate, understand, or clarify work previously performed by Employee or other work-related issues relating to Employee’s employment. Employee also agrees that he will cooperate, assist, and make himself reasonably available to API personnel or API agents on an as-needed basis in order to respond to or address any complaint or issue raised by any person or entity that does/did business with API or is/was associated with API in any way. Finally, Employee agrees that he will provide truthful and

-9-

accurate sworn testimony in the form of deposition, affidavit, and/or otherwise if requested by current API personnel. API will strive to keep the need for future assistance to a minimum, and will reimburse Employee for reasonable out-of-pocket expenses, including, without limitation, travel expenses, incurred as a result of Employee’s assistance, unless such remuneration would be inappropriate or otherwise prohibited under existing law.

15. Nonwaiver. The waiver by API of a breach of any provision of this Agreement by Employee shall not operate or be construed as a waiver of any subsequent breach by Employee.
