The Company may make any tax withholding from any payments made pursuant to this SECTION 3(a) that it deems to be necessary under applicable tax laws. If there is a Change in Control (as such term is defined in Exhibit A hereto) after the Termination Date and while Executive is entitled to any payments pursuant to SECTION 3(a)(i)(A) hereof, all such payments pursuant to such SECTION 3(a)(i)(A) hereof which remain unpaid as of the Change in Control shall be paid in one lump sum as of the date of the Change in Control. -2- <Page> Except as specifically provided in this Agreement, no other amounts will be payable by the Company to Executive. (b) The Company has previously granted to Executive options to purchase shares of the Company's common stock as set forth in Exhibit B hereto. Provided that Executive does not revoke this Agreement as provided at the end of this Agreement, then, on the Effective Date: (i) all such stock options which have not vested prior to the Termination Date shall immediately vest; and (ii) all such options which (x) are marked with an asterisk on said Exhibit B shall remain exercisable until the earlier to occur of (1) the third anniversary of the Termination Date and (2) the final stated expiration date of the option or restricted stock and (y) which are not so marked with an asterisk shall remain exercisable until the earlier to occur of (1) the date which is 90 days after the Termination Date and (2) the final stated expiration date of the option or restricted stock. All shares of the Company's common stock underlying such options will, when and if exercised, be issued to Executive pursuant to a Registration Statement on either Form S-3 or Form S-8 and, as such, will not be deemed to be "restricted securities" as contemplated by Rule 144 promulgated under the Securities Act of 1933, as amended. (c) Provided that Executive does not revoke this Agreement as provided at the end of this Agreement, then, beginning on the Effective Date, Executive shall be entitled, at the Company's expense, to the benefits that Executive was receiving or to which Executive was entitled as of the Termination Date pursuant to Section 4 of the Employment Agreement (other than the benefits described in Section 4(b) of the Employment Agreement) for a period of time following the Termination Date ending on the first to occur of (i) the third anniversary of the Termination Date or (ii) the date on which Executive commences full-time employment with another employer, but only if and to the extent Executive is eligible to receive through such other employer benefits which are at least equivalent on an aggregate basis to those benefits Executive was receiving or to which Executive was entitled under Section 4 of the Employment Agreement as of the Termination Date. If because of limitations required by third parties or imposed by law, Executive cannot be provided such benefits through the Company's plans, then the Company will provide Executive with substantially equivalent benefits, on an aggregate basis, at the Company's expense. For purposes of the determination of any benefits which require a particular period of employment by the Company and/or the attainment of a particular age while employed by the Company in order to be payable, Executive shall be treated as having continued in the employment of the Company during such period of time as Executive is entitled to receive benefits under this SECTION 3(c). At such time as the Company is no longer required to provide Executive with life and/or disability insurance, as the case may be, Executive shall be entitled, at Executive's expense, to convert such life and disability insurance, as the case may be, into individually owned policies, except if and to the extent such conversion is not available -3- <Page> from the provider of such insurance. Executive acknowledges and agrees that his right to continue group health plan coverage for a period of time after the Termination Date in accordance with the terms and conditions of the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") shall be deemed to be satisfied by Executive's receipt of coverage as provided herein, to the extent that such benefit equals or exceeds the time period specified in COBRA. Executive agrees to execute any elections and forms and take such other action as may be required by the Company to waive his rights to COBRA coverage consistent with the foregoing. In the event that Executive's eligibility for health insurance benefits pursuant to this paragraph terminates before the expiration of the time period specified in COBRA, Executive shall maintain the right to continue group health plan coverage in accordance with the terms and conditions of COBRA for that period of time remaining under COBRA. Except as specifically modified herein, all other regular COBRA procedures and rules will apply. Executive acknowledges that Company may modify its premium structure, the terms of its plans and the coverage of the plans, including the termination of all or part of a plan. Executive agrees to notify Company when Executive is eligible to participate and/or begins participation in another group health plan. (d) Provided that Executive does not revoke this Agreement as provided at the end of this Agreement, then, on the Effective Date, Executive shall retain possession of the Sony laptop computer and home facsimile machine currently utilized by him in fulfilling his employment duties, PROVIDED, HOWEVER, that any confidential information (as defined in SECTION 11(a) below) and any software on the aforementioned computer that is licensed only to the Company shall be returned to the Company. (e) Provided that Executive does not revoke this Agreement as provided at the end of this Agreement, then, Executive shall be paid any amounts for expense reimbursement and similar items which have been properly incurred in accordance with the provisions of the Employment Agreement prior to the Termination Date and have not yet been paid, including without limitation any sums due under Sections 2(c), 4(c), 4(d) and 4(f) thereof and the last sentence of Section 10 thereof, provided that Executive provides the appropriate documentation of such expenses within 30 business days of the Termination Date. (f) Provided that Executive does not revoke this Agreement as provided at the end of this Agreement, then, within 90 days of the Effective Date, Executive shall pay to the Company, in repayment of the advance made by the Company to the Executive for payment of Medicare taxes payable in connection with certain option exercises, the amount of $25,243.22, plus interest thereon from April 26, 2002 to the date of repayment at a daily rate equal to $4.07. 4. WELFARE BENEFIT PLAN CONTRIBUTIONS AND ACCRUALS. After the Termination Date, except as provided in SECTION 3(c) and SECTION 5 hereof, the Company shall not be obligated to continue, pay for, or provide Executive's health, dental, disability, life insurance and any other "welfare benefits" (as such term is defined under Section 3(1) of the Employment Retirement Income Security Act of 1974, as amended ("ERISA")) or fringe benefits or perquisites. -4- <Page> 5. PENSION PLAN CONTRIBUTIONS AND ACCRUALS. After the Termination Date, no further contributions, either by Executive or by the Company, shall be made to, or benefits accrued under, any employee pension benefit plan (as defined in Section 3(2) of ERISA) or deferred compensation plan or agreement (collectively, the "Company Plans") on behalf of Executive; PROVIDED, HOWEVER, Executive shall be entitled to receive any vested benefits due to him under such Company Plans as determined in accordance with the terms and conditions of such Company Plans and applicable law. 6. RECIPROCAL RELEASES AND WAIVERS OF CLAIMS. (a) Except with respect to a claim for any compensation or benefits under the employee benefit plans in which Executive participated by virtue of his employment, Executive, as his free and voluntary act, on behalf of himself and his spouse, dependents, heirs, executors, administrators, representatives, attorneys, and permitted assigns, hereby fully releases and discharges the Company, and its successors and assigns, and the past, present and future owners, directors, officers, employees, and agents of the Company, personally and in their official capacities (collectively, the "Releasees"), of and from any and all debts, obligations, claims, demands, judgments or causes of action of any kind whatsoever, known or unknown, in tort, contract, by statute or on any other basis, for equitable relief, compensatory, punitive or other damages, expenses (including attorneys' fees), reimbursements of costs of any kind, including but not limited to, any and all claims, demands, rights and/or causes of action, including, without limitation, any negligence claims and those which might arise out of allegations relating to a claimed breach of the Employment Agreement or any other aspect of Executive's employment relationship with the Company or stock option agreements, or relating to purported employment discrimination or civil rights violations, such as, but not limited to, those arising under Title VII of the Civil Rights Act of 1964, the Civil Rights Acts of 1866 and 1871, Executive Order 11246, as amended, the Age Discrimination in Employment Act, the Employee Retirement Income Security Act of 1974, the Equal Pay Act of 1963, the Rehabilitation Act of 1973, the Civil Rights Act of 1991, the Americans with Disabilities Act, and the Family and Medical Leave Act, as each such Act may be amended from time to time, or any other applicable federal, state or local law, regulation or other requirement, which Executive might have or assert against any of the Releasees by reason of (i) any event which occurred on or before the date that Executive executes this Agreement, in connection with Executive's employment by the Company, and all circumstances related thereto, (ii) the termination of his employment (including any rights of Executive under the Employment Agreement or any other employment contract), or (iii) any matter, cause or thing whatsoever which may have occurred prior to the date that Executive executes this Agreement. (b) Executive acknowledges that Company's agreement to provide Executive with the payments and other benefits recited in SECTION 3 hereof is in consideration for Executive's release and waiver of claims, demands and causes of action as set forth in the immediately preceding paragraph in addition to Executive's other agreements contained herein. Executive understands and acknowledges that Executive would not receive the payments and benefits recited in SECTION 3 hereof but for his execution of this Agreement. -5- <Page> (c) The Company hereby releases and discharges Executive, and his heirs, executors, administrators, representatives, attorneys, and permitted assigns, of and from any and all debts, obligations, claims, demands, judgments or causes of action of any kind whatsoever, known or unknown, in tort, contract, by statute or on any other basis, for equitable relief, compensatory, punitive or other damages, expenses (including attorneys' fees), reimbursements of costs of any kind, including but not limited to, any and all claims, demands, rights and/or causes of action, including breach of fiduciary duty, breach of the duty of confidentiality, tortious interference with contract, defamation, libel, civil conspiracy, false light, invasion of privacy, actions which might arise out of allegations relating to a claimed breach of the Employment Agreement or any other aspect of Executive's employment relationship with the Company relating to purported employment discrimination or civil rights violations, which the Company might have or assert against Executive, but only with respect to or by reason of any event which occurred prior to the date that the Company executes this Agreement. 7. COOPERATION AND INDEMNIFICATION IN THE EVENT OF THIRD-PARTY LITIGATION. (a) In the event that any third-party (including, without limitation, any private party or governmental entity) asserts a claim or legal cause of action, initiates a governmental review, or initiates a legal proceeding (civil or criminal), with respect to any events or matters with which Executive was formerly involved as an employee of Company, the Company shall indemnify Executive to the same extent, and subject to the same terms, conditions and limitations, as would be applicable under the by-laws of the Company to an individual who is an officer of the Company. To the extent permitted by the Company's applicable director and officer insurance policy, Executive shall be entitled to coverage under such policy for actions taken in the scope of his service as an officer of the Company. (b) In consideration for such indemnification, Executive agrees to make himself freely available to cooperate in the defense and in the preparation of the legal response if any third party (including, without limitation, any private party or governmental entity) asserts a claim or legal cause of action, initiates a governmental review, or initiates a legal proceeding (civil or criminal), with respect to any events or matters with which Executive was formerly involved as an employee of Company and, in such a case, the Company shall reimburse Executive for reasonable travel costs in connection with rendering any such assistance. Executive agrees to cooperate to the fullest extent of his abilities with Company and, if requested by Company to do so, with any attorney, expert or other person Company may designate, in the investigation, defense and resolution of any threatened or asserted litigation, claim, potential claim, or investigation initiated by or involving the Company, including, without limitation, truthfully testifying on behalf of Company in connection with any such investigation or proceeding. The Company agrees to use reasonable efforts to schedule any work or appearances of Executive required pursuant to this SECTION 7(b) so as to not unreasonably conflict with Executive's employment with another employer.

Such hourly fee shall be payable for all hours actually devoted to such assistance (including hours in transit) to the extent permitted by applicable legal or court requirements, and will not be limited to 8 hours per day if the hours of active assistance (and travel) exceed 8 hours in any given day. (d) Subject to the scope of the indemnification in paragraph (a) above, in the event of a civil action commenced by a private party which implicates Executive in connection with his conduct during his period of service as an employee of the Company, the Company reserves the right and discretion to retain counsel to jointly represent the Company and Executive, unless and until such counsel determines that the interests of the Company and Executive pose a conflict of interest for such counsel under the applicable code of professional conduct. In the event that separate counsel is necessary for Executive, he may select counsel of his choice subject to the approval of the Company which shall not be unreasonably withheld. The Company will reimburse the reasonable attorney's fees and costs of counsel for Executive, and such reimbursement will be paid as services are rendered, subject to a right of the Company to recover the amount of such payments from Executive in the event, and to the extent, that a court or agency finds that the relevant actions of Executive were either (i) unlawful (unless the Company was found to have directed the unlawful action) or (ii) outside the scope of his duties as an employee. (e) As used in this SECTION 7, the term "reasonable attorneys' fees" shall not include any attorney time or expense for the purpose of initiating or maintaining any counterclaim by Executive against the Company or any private party or governmental entity, unless the Companythen consents, in its sole discretion and in writing, to cover Executive's attorneys' fees for any such counterclaim. (f) The provisions of this SECTION 7 shall expire six (6) years from the Termination Date; provided that if a claim is made but final resolution thereof has not been obtained within such six-year period, the provisions of this SECTION 7 shall continue as to that claim until final resolution is obtained. 8.
