COVENANTS

1.                                       Consideration.

(a)                                  The Company agrees to pay Employee a lump sum of $82,500, less applicable withholdings.  This payment will be made to Employee within ten (10) business days after the Effective Date of this Agreement.

(b)                                 Stock.  The Parties agree that for purposes of determining the number of shares of the Company’s common stock which Employee is entitled to purchase from the Company, pursuant to the exercise of outstanding options, the Employee will be considered to have vested only up to the Termination Date.  Employee acknowledges that as of the Termination Date, he will have vested in 218,039 options and no more.  In accordance with the terms of the Stock Agreements, these vested options are subject to cancellation 30 days after the Termination Date and therefore, the Employee must exercise by August 19, 2005 when the remaining vested options will expire.  The exercise of any stock options shall continue to be subject to the terms and conditions of the Stock Agreements.

(c)                                  Benefits.  Employee’s health insurance benefits will cease on July 31, 2005, subject to Employee’s right to continue his health insurance under COBRA.  The Company shall reimburse Employee for the payments he makes for COBRA coverage for a period of six (6) months beginning August 1, 2005 and concluding on January 31, 2006 (the “Benefits Period”).  The Company shall make these COBRA reimbursement payments to Employee within ten (10) days following Employee’s provision to the Company of documentation substantiating his payments for COBRA coverage.  Employee’s participation in all other benefits and incidents of employment (including, but not limited to, the accrual of vacation and paid time off, and the vesting of stock options) ceased on the Termination Date; provided, however, that that if during the Benefits Period Employee engages in Competition or breaches the covenants in this Agreement, all payments pursuant to this subsection will immediately cease.  For purposes of this Agreement, “Competition” will mean Employee’s direct or indirect engagement in (whether as an employee, consultant, agent, proprietor, principal, partner, stockholder, corporate officer, director or otherwise), or ownership interest in or participation in the financing, operation, management or control of, any person, firm, corporation or business that competes with Company or is a customer of the Company.

2.                                       Confidential Information.  Employee shall continue to comply with the terms and conditions of the Confidentiality Agreement, and maintain the confidentiality of all of the Company’s confidential and proprietary information.  Employee shall also return to the Company all of the Company’s property, including all confidential and proprietary information, and all documents and information that Employee obtained in connection with his employment with the Company, on or before the Effective Date of this Agreement.

3.                                       Payment of Salary.  Employee acknowledges and represents that the Company has paid all salary, wages, bonuses, accrued vacation, housing allowances, relocation costs, interest, severance, stock, stock options, outplacement costs, fees, commissions and any and all other benefits and compensation due to Employee.

4.                                       Release of Claims.  Employee agrees that the foregoing consideration represents settlement in full of all outstanding obligations owed to Employee by the Company and its current and former officers, directors, employees, agents, investors, attorneys, shareholders, administrators, affiliates, divisions, subsidiaries, predecessor and successor corporations and assigns (the “Releasees”).  Employee, on his own behalf, and on behalf of his respective heirs, family members, executors, agents, and assigns, hereby fully and forever releases the Company and the other Releasees from, and agrees not to sue concerning, any claim, duty, obligation or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Employee may possess arising from any omissions, acts or facts that have occurred up until and including the Effective Date of this Agreement including, without limitation:

10.                                 No Cooperation.  Employee agrees that he will not act in any manner that might damage the business of the Company.  The Parties acknowledge that Employee’s employment with any of the Company’s competitors shall not, in and of itself, constitute a breach of this provision.  Employee further agrees that he will not knowingly counsel or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any third party against any of the Releasees, unless under a subpoena or other court order to do so.  Employee agrees both to immediately notify the Company upon receipt of any such subpoena or court order, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or court order to the Company.  If approached by anyone for counsel or assistance in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints against any of the Releasees, Employee shall state no more than that he cannot provide counsel or assistance.
