     (B) if any such plan is not fully insured, the Executive shall be required to pay the full COBRA premium and the Company will reimburse the Executive for a portion of the COBRA premium charged to the Executive that represents the Company’s allocable share of the cost of coverage for similarly situated active employees of the Company under such plan;

provided, however, that as a condition of receiving the payments in paragraphs (ii) through (iv), the Executive must execute and return the Separation Agreement attached hereto as Exhibit A to the Company within five (5) days following his termination of employment, and not return a revocation of the Separation Agreement for the Company’s receipt within seven (7) days after the Executive executes the Separation Agreement.”

     In consideration for the mutual promises contained in this Agreement, the Company and Executive agree as follows:

1. Employment Termination.

     (a) General Terms. The Company and Executive agree that:

          (1) Executive ceased to be an employee and officer of the Company as of _________, 2008 (the “Termination Date”); and

          (2) Executive hereby resigns, effective as of the date he signs this Agreement, from any and all titles and positions with the Company. Executive agrees to tender and memorialize his resignation from any and all such positions in any other manner and form as the Company may reasonably request.

     (b) Satisfaction of Obligations. The payments, benefits and other consideration provided by the Company under Section 4(b) or 5(c), as applicable, of the Amendment are in full and final satisfaction of all obligations that the Company has to Executive, except as provided in Section 3(a) hereof. Without limiting the foregoing, these payments and benefits replace any and all obligations of the Company under any and all letters, agreements, understandings, plans and policies, relating to Executive’s employment and severance, except as provided in Section 3(a) hereof. Executive agrees that the payments and benefits described in Section 4(b) or 5(c), as applicable, of the Amendment are adequate consideration for (i) the agreements he makes in this Agreement, and (ii) the releases he gives pursuant to this Agreement.

     (c) No Other Payments or Benefits. Executive shall not be eligible for, and he will not receive, any payments or benefits from the Company, or under any plan,

agreement, or arrangement in which Executive or the Company are a party or participate which are not expressly set forth in this Agreement.

2. Cooperation.

     (a) Nondisparagement. Executive agrees that he shall not, directly or indirectly, in any capacity or manner, make, cause, encourage or assist to be made any statements, comments or remarks, whether oral, in writing or electronically transmitted, which might reasonably be considered to be derogatory, defamatory or critical of, or negative towards, or to malign, harm, defame, disparage or damage the reputation of the Company or any of the other Released Parties (as defined below). This section shall not apply to any communications that are (i) intended to comply with the requirements and policies of any federal or state agency, (ii) intended to cooperate with any investigation or request for information from any state or federal government agency, or (iii) made in connection with any judicial or administrative proceeding. Executive agrees that he will not make any statements about any of the Released Parties to the press (including without limitation any newspaper, magazine, radio station or television station) without the prior written consent of the Chairman of the Board of Directors of the Company

     (b) Cooperation as a Witness. Executive shall cooperate with the Company as a witness in all matters about which he has knowledge as a result of his prior positions with the Company if the Company requests his testimony. To the extent practicable and within the control of the Company, the Company will use reasonable efforts to schedule the timing of his participation in any such witness activities in a reasonable manner to take into account his then-current employment, and will pay the reasonable documented out-of-pocket expenses that the Company pre-approves and that Executive incurs for travel required by the Company with respect to those activities.

3. General Release of Claims by Executive.

     (a) Release. As a material inducement for the Company to enter into this Agreement, Executive hereby forever, irrevocably and unconditionally, releases and discharges the Company and other Released Parties (as defined below) from any and all charges, claims, liabilities, agreements, damages, causes of action, suits, costs, losses, debts and expenses (including attorneys’ fees and costs actually incurred) of any nature whatsoever, known or unknown, which he now has, or claims to have, or which Executive at any time had, or claimed to have, or which Executive at any time hereafter may have, or claim to have, against the Company, in each case as to acts or omissions occurring up to and including the date Executive signs his Agreement, including, without limitation, any claim of breach of fiduciary duty, rights arising out of alleged violations of any contracts, express or implied, any covenant of good faith and fair dealing, express or implied, or any tort, or any legal restrictions on the Company’s right to terminate employees, or any federal, state or other governmental statute, regulation, or ordinance (all such matters hereby released, collectively referred to as “Claims”).

This release will not apply to any claim for payments or benefits Executive may have under the terms of the Amendment, any rights he may have with respect to vested stock options or any rights to the “Accrued Obligations” as defined in the Employment Agreement.

     (b) Released Parties. As used in this Agreement, the “Released Parties” are the Company and all of its related companies, partnerships or joint ventures, including but not limited to, direct and indirect parent and subsidiary companies, and their predecessors and successors; and, with regard to each of those entities, except for Executive, all of its past and present employees, officers, directors, stockholders, owners, representatives, assigns, attorneys, agents, insurers, employee benefit programs (and the trustees, administrators, fiduciaries and insurers of these programs) and any other persons acting by, through, under or in concert with any of the persons or entities listed in this subsection. Executive understands that this release covers him and anyone who might have a claim through him or because of him, such as a past, current or future spouse, his family, heirs, executors, representatives, agents and their successors and assigns.

     (c) No Lawsuits. Executive has not filed or caused to be filed any lawsuit, complaint or charge with respect to any Claim he is releasing in this Agreement. Executive agrees never to institute, or participate in any action against any of the Releasees with respect to any Claim released by this Agreement, except as required by subpoena, court order, or other compulsory process and except that he may participate in an investigation or proceeding conducted by an agency of the United States government or of any state. Executive has not assigned or transferred any Claim he is releasing, nor has he purported to do so. Notwithstanding any language herein to the contrary, Executive understands that nothing in this Release prohibits Executive from filing or pursuing a charge of discrimination with the Equal Employment Opportunity Commission (“EEOC”) or a claim with the National Labor Relations Board (“NLRB”); provided that, by signing this Agreement, Executive agrees to waive and relinquish any personal or monetary gain that would otherwise result from such EEOC or NLRB claim.

     (d) Release of Age Claims. Executive expressly and specifically waives any and all rights or claims which he may have under the Age Discrimination in Employment Act of 1967, 29 U.S.C. Section 621 et seq. (“ADEA”). Executive acknowledges that this waiver is knowingly and voluntarily made and specifically agrees that: (i) this waiver is written in a manner that he understands; (ii) this waiver specifically relates to rights and claims under the ADEA; (iii) he does not waive any rights or claims that may arise after the date he signs this Agreement; (iv) he is waiving these rights or claims in exchange for substantial consideration in excess of anything of value to which he is otherwise entitled to receive; (v) he has been advised in writing, and given the opportunity, to consult with an attorney before signing this Agreement; (vi) he has been given a period of 21 days to review this Agreement; and (viii) after Executive has signed this Agreement, he may revoke this Agreement by providing written notice to the Companies as provided in Section 6 hereof within 7 days following his execution of the Agreement. Executive specifically agrees that the 21-day period that he has to review this Agreement (including

this release) and to consult an attorney began to run on the date he executed the Amendment, and that any changes made since that date have not extended or restarted that 21-day period.

4. Consequences of Violating Executive’s Agreements or Breaching Executive’s Release.

Executive understands that his agreements in Section 2 and the releases provided in this Agreement are especially important reasons why the Company offered Executive the Retention Bonus referenced in the Amendment. Executive agrees that, in the event of his actual or threatened breach of any agreement, any release or any other terms of this Agreement, the Company, in addition to all other rights and remedies available to it at law or in equity, may recover damages from Executive, and will be entitled to an injunction restraining Executive from breaching his agreements, the releases or any other terms of this Agreement. Executive also agrees to pay the reasonable attorneys’ fees and related damages the Company may incur as a result of Executive breaching his agreements, a release or any other term(s) of this Agreement or if any representation Executive made in this Agreement was false when made. Executive understands that no provision in this Agreement is to be construed as a waiver or prohibition against the Company pursuing any other legal or equitable remedy for a breach of this Agreement. Executive understands, however, that this section will not apply to any challenge of the validity of the release given under the ADEA.

5. Miscellaneous Provisions.
