ARTICLE 4: EFFECT OF TERMINATION AND CHANGE IN CONTROL ON COMPENSATION; ADDITIONAL PAYMENTS

4.1 Defined Terms. For purposes of this Article 4, the following terms shall have the meanings indicated:

“Base Amount” shall be the “base amount” of Key Employee’s annual compensation, determined in accordance with Section 280(g) of the Internal Revenue Code of 1986, as amended.

“Change in Control” means (i) a merger of the Company with another entity, a consolidation involving the Company, or the sale of all or substantially all of the assets of the Company to another entity if, in any such case, (A) the holders of equity securities of the Company immediately prior to such transaction or event do not beneficially own immediately after such transaction or event equity securities of the resulting entity entitled to 40% or more of the votes then eligible to be cast in the election of directors generally (or comparable governing body) of the resulting entity in substantially the same proportions that they owned the equity securities of the Company immediately prior to such transaction or event or (B) the persons who were members of the Board of Directors immediately prior to such transaction or event shall not constitute at least a majority of the board of directors of the resulting entity immediately after such transaction or event, (ii) the dissolution or liquidation of Company, (iii) when any person or entity, including a “group” as contemplated by Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, acquires or gains ownership or control (including, without limitation, power to vote) of more than 60% of the combined voting power of the outstanding securities of, (A) if the Company has not engaged in a merger or consolidation, Company, or (B) if the Company has engaged in a merger or consolidation, the resulting entity, or (iv) as a result of or in connection with a contested election of directors, the persons who were members of the Board of Directors immediately before such election shall cease to constitute a majority of the Board of Directors. For purposes of the preceding sentence, (1) “resulting entity” in the context of a transaction or event that is a merger, consolidation or sale of all or substantially all assets shall mean the surviving entity (or acquiring entity in the case of an asset sale) unless the surviving entity (or acquiring entity in the case of an asset sale) is a subsidiary of another entity and the holders of common stock of the Company receive capital stock of such other entity in such transaction or event, in which event the resulting entity shall be such other entity, and (2) subsequent to the consummation of a merger or consolidation that does not constitute a Change in Control, the term “Company” shall refer to the resulting entity and the term “Board of Directors” shall refer to the board of directors (or comparable governing body) of the resulting entity. Notwithstanding the foregoing, if the Company engages in any transaction approved by the shareholders of the Company and by the Board of Directors of the Company, and the Board of Directors of the Company (or any successor of the Company by merger, consolidation or otherwise) remains the Board of Directors of the Company (or any successor of the Company by merger, consolidation or otherwise) immediately following such transaction, regardless of whether shareholders of the Company own a majority of the outstanding securities of the Company (or any successor of the Company by merger, consolidation or otherwise), then such transaction shall not be considered a “Change in Control.”

“Termination Benefits” means (i) a lump sum cash payment equal to three (3) times Key Employee’s “Base Amount”, less $1.00.

“Health Coverage” means that if Key Employee elects to continue coverage for himself or his eligible dependents under the Company’s group health plans pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), during the twelve-month period commencing on the date of Key Employee’s termination of employment from the Company (the “Severance Period”), then throughout the Severance Period the Company shall promptly reimburse Key Employee on a monthly basis for the difference between the amount Key Employee pays to effect and continue such coverage and the employee contribution amount that active senior employees pay for the same or similar coverage under Company’s group health plans. Further, if after the Severance Period Key Employee continues his COBRA coverage and Key Employee’s COBRA coverage terminates at any time during the eighteen-month period commencing on the day immediately following the last day of the Severance Period (the “Extended Coverage Period”), then the Company shall provide Key Employee (and his eligible dependents) with health benefits substantially similar to those provided under its group health plans for active employees for the remainder of the Extended Coverage Period at a cost to Key Employee that is no greater than the cost of COBRA coverage; provided, however, that the Company shall use its reasonable efforts so that such health benefits are provided to Key Employee under one or more insurance policies (or such other manner) so that reimbursement or payment of benefits to Key Employee thereunder shall not result in taxable income to Key Employee. Notwithstanding the preceding provisions of this paragraph, the Company’s obligation to reimburse Key

Employee during the Severance Period and to provide health benefits to Key Employee during the Extended Coverage Period shall immediately end if and to the extent Key Employee becomes eligible to receive health plan coverage from a subsequent employer (with Key Employee being obligated hereunder to promptly report such eligibility to the Company).

4.2 Termination By Expiration. If Key Employee’s employment hereunder shall terminate upon expiration of the term provided in paragraph 2.1 hereof because either party has provided the notice contemplated in such paragraph, then all compensation and all benefits to Key Employee hereunder shall continue to be provided until the expiration of such term and such compensation and benefits shall terminate contemporaneously with termination of his employment.

4.3 Termination By the Company. If Key Employee’s employment hereunder shall be terminated by the Company prior to expiration of the term provided in paragraph 2.1, then, upon such termination, regardless of the reason therefore, all compensation and benefits to Key Employee hereunder shall terminate contemporaneously with the termination of such employment; provided, however, that, subject to paragraph 4.7 below, if such termination shall be for any reason other than those encompassed by paragraph 2.2(i), 2.2(ii), or 2.2(iii), then the Company shall provide Key Employee with the Termination Benefits. Any lump sum cash payment due to Key Employee pursuant to the preceding sentence shall be paid to Key Employee within five business days of the date of Key Employee’s termination of employment with the Company; provided, however, that if the lump sum cash payment would be subject to additional taxes and interest under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), then payment of the lump sum cash payment shall be deferred to the extent required to avoid such additional taxes and interest.

4.4 Termination By Key Employee. If Key Employee’s employment hereunder shall be terminated by Key Employee prior to expiration of the term provided in paragraph 2.1, then, upon such termination, regardless of the reason therefore, all compensation and benefits to Key Employee hereunder shall terminate contemporaneously with the termination of such employment; provided, however, that, subject to paragraph 4.7 below, if such termination occurs for Good Reason, then the Company shall provide Key Employee with the Termination Benefits. Any lump sum cash payment due to Key Employee pursuant to this paragraph shall be paid to Key Employee within five business days of the date of Key Employee’s termination of employment with the Company; provided, however, that if the lump sum cash payment would be subject to additional taxes and interest under Section 409A of the Code, then payment of the lump sum cash payment shall be deferred to the extent required to avoid such additional taxes and interest.

4.5 Change in Control Benefits. If Key Employee is employed by the Company on the date upon which a Change in Control occurs, then the Company shall provide Key Employee with the Termination Benefits (other than Health Coverage), which benefits shall be determined as if Key Employee’s employment by the Company terminated on the date of such Change in Control; provided, however, that, if Key Employee is entitled to Termination Benefits under paragraph 4.3 or 4.4 of this Agreement as of the date of such Change in Control, then Key Employee shall not also be entitled to additional Termination Benefits under this paragraph. Any lump sum cash payment due to Key Employee pursuant to the preceding sentence shall be paid to Key Employee within five business days of the date of the Change in Control.

4.6 Parachute Payments. Notwithstanding anything to the contrary in this Agreement, if Key Employee is a “disqualified individual” (as defined in Section 280G(c) of the Code), and the benefits provided for in this Article, together with any other payments and benefits which Key Employee has the right to receive from the Company and its affiliates, would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the benefits provided hereunder (beginning with any benefit to be paid in cash hereunder) shall be either (1) reduced (but not below zero) so that the present value of such total amounts and benefits received by Key Employee will be one dollar ($1.00) less than three times Key Employee’s Base Amount and so that no portion of such amounts and benefits received by Key Employee shall be subject to the excise tax imposed by Section 4999 of the Code or (2) paid in full, whichever produces the better net after-tax position to Key Employee (taking into account any applicable excise tax under Section 4999 of the Code and any other applicable taxes). The determination as to whether any such reduction in the amount of the benefits provided hereunder is necessary shall be made initially by the Company in good faith. If a reduced benefit is provided hereunder in accordance with clause (1) of the first sentence of this paragraph and through error or otherwise that payment, when aggregated with other payments and

benefits from the Company (or its affiliates) used in determining if a “parachute payment” exists, exceeds one dollar ($1.00) less than three times Key Employee’s base amount, then Key Employee shall immediately repay such excess to the Company upon notification that an overpayment has been made.

4.7 Release and Full Settlement. Anything to the contrary herein notwithstanding, as a condition to the receipt of Termination Benefits under paragraph 4.3 or 4.4 hereof, Key Employee shall first execute a release, in the form established by the Board of Directors, releasing the Board of Directors, the Company, and the Company’s parent corporation, subsidiaries, affiliates, and their respective shareholders, partners, officers, directors, employees, attorneys and agents from any and all claims and from any and all causes of action of any kind or character including, but not limited to, all claims or causes of action arising out of Key Employee’s employment with the Company or its affiliates or the termination of such employment, but excluding all claims to vested benefits and payments Key Employee may have under any compensation or benefit plan, program or arrangement, including this Agreement. The performance of the Company’s obligations hereunder and the receipt of any benefits provided under paragraphs 4.3 and 4.4 shall constitute full settlement of all such claims and causes of action.

4.8 No Duty to Mitigate Losses. Key Employee shall have no duty to find new employment following the termination of his employment under circumstances that require the Company to pay any amount to Key Employee pursuant to this Article 4. Except to the extent Key Employee becomes eligible to receive health plan coverage from a subsequent employer as provided in paragraph 4.1 with respect to Health Coverage, any salary or remuneration received by Key Employee from a third party for the providing of personal services (whether by employment or by functioning as an independent contractor) following the termination of his employment under circumstances pursuant to which this Article 4 apply shall not reduce the Company’s obligation to make a payment to Key Employee (or the amount of such payment) pursuant to the terms of this Article 4.

4.9 Liquidated Damages. In light of the difficulties in estimating the damages for an early termination of Key Employee’s employment under this Agreement, the Company and Key Employee hereby agree that the payments, if any, to be received by Key Employee pursuant to this Article 4 shall be received by Key Employee as liquidated damages.

4.10 Other Benefits. This Agreement governs the rights and obligations of Key Employee and the Company with respect to Key Employee’s base salary and certain perquisites of employment. Except as expressly provided herein, Key Employee’s rights and obligations both during the term of his employment and thereafter with respect to stock options, restricted stock, incentive and deferred compensation, life insurance policies insuring the life of Key Employee, and other benefits under the plans and programs maintained by the Company shall be governed by the separate agreements, plans and other documents and instruments governing such matters.
