W I T N E S S E T H:

WHEREAS, pursuant to an Employment Agreement dated November 13, 2001 (“the Employment Agreement”), Executive has been employed by the Company as its Chairman and Chief Executive Officer; and

WHEREAS, as a result of the Company’s recent bankruptcy and reorganization, Executive desires to resign from his employment, and the Company desires to accept said resignation; and

WHEREAS, the Company and Executive wish to resolve all matters and issues between them arising from or relating to Executive’s employment by the Company.

ARTICLE I — CONSIDERATION

Section 1.1. Resignation. Executive, through his signature below, voluntarily resigns from his position as Chairman and Chief Executive Officer of the Company effective September 15, 2003, and further resigns from his employment with the Company effective November 28, 2003 (“Date of Resignation”). The Company, through its execution below, hereby consents to and accepts Executive’s resignation. The parties hereby acknowledge and agree that Executive’s resignation hereunder shall be deemed a voluntary termination by Executive with Good Reason, as that term is defined in the Employment Agreement, and the Company further waives the requirement of fifteen (15) calendar days written notice of same from Executive. Executive’s employment records with the Company will reflect the voluntary nature of the cessation of his employment, and the Company and Executive each expressly acknowledge that he has not been “discharged” or “terminated” by the Company, constructively or otherwise. The parties acknowledge and agree that Executive serves as a director of the Company pursuant to the terms of the Company’s Amended Joint Prepackaged Reorganization Plan, dated September 3, 2003 (the “Plan of Reorganization”), and that Executive’s resignations from his position as Chairman and Chief Executive Officer and from his employment with the Company shall not be construed as a resignation from service as a director of the Company.

Section 1.2. Separation Pay. Upon the Effective Date of this Agreement as defined in §4.7 hereof, the Company will make payment to Executive in the lump sum amount of Six Hundred Twenty Four Thousand Six Hundred Ninety Six Dollars and Fifty Eight Cents ($624,696.58) less applicable payroll taxes and withholdings (the “Separation Payment”).

Section 1.3. Restrictive Covenants. Upon the Effective Date of this Agreement as defined in §4.7 hereof, and as consideration for Executive’s agreements set forth in Article III of this Agreement, the Company will make payment to Executive in the lump sum amount of Five Hundred Fourteen Thousand Dollars ($514,000.00) (the “Restrictive Covenants Payment”). The Company shall not withhold any amounts from the Restrictive Covenants Payment, and Executive shall assume responsibility for the payment of any of Executive’s portion of taxes and withholdings incurred in connection with the Restrictive Covenants Payment, including interest and penalties with respect to both the Company’s and Executive’s portions in the event that Executive fails to include the amount in income and pay the income tax thereon. The parties further agree that the Company may issue or file a Form 1099 or other notice to the Internal Revenue Service regarding the Restrictive Covenants Payment.

Section 1.4. Group Insurance Coverage. For the period continuing through January 30, 2006, the Company shall continue to provide to Executive, or cause to be provided to him, group health, dental, vision, and group life insurance benefits at the same level and to the same extent such benefits were provided to him immediately prior to the Date of Resignation. If at any time between the Date of Resignation and January 30, 2006, the Company is not able to continue to provide to Executive group health, dental, vision, or group life insurance benefits as described in the preceding sentence, then the Company shall reimburse Executive for his costs in purchasing health, dental, vision, or life insurance coverage providing at least equivalent coverage, with such reimbursement to be in an amount which, after taxes on the receipt of such reimbursement, shall equal such cost to Executive. At the conclusion of the period continuing through January 30, 2006, Executive shall be entitled to continuation of coverage under the Company’s health insurance plan at his own expense pursuant to any rights he may have under the federal Consolidated Omnibus Budget Reconciliation Act, as amended (“COBRA”), part VI of Subtitle B of Title I of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended; Internal Revenue Code §4980(B)(f).

For a period of six (6) years following the Date of Resignation, the Company will maintain Directors & Officers Liability Insurance (“tail”) coverage for Executive to insure against claims arising out of his service as a Director or Officer of the Company prior to September 15, 2003. As to Executive’s continued service on the Company’s Board of Directors, the Company will maintain customary Directors & Officers Liability Insurance coverage for Executive to insure against claims arising out of his service on the Company’s Board of Directors, and such coverage shall be at least equivalent to the coverage provided to other directors.

Section 1.9. Automobile Use. The Company will continue to provide Executive with continued possession and use of the automobile leased by the Company and assigned to Executive as of the Date of Resignation, and Executive shall have use of such automobile through January 30, 2006, provided that Executive reimburses the Company for the lease payments by submitting to the Company on a monthly basis payments in the amount of Seven Hundred Three Dollars and Thirty-Two Cents ($703.32). Executive’s monthly payments for the automobile shall be due to the Company on or before the fifth calendar day of each month. In the event that Executive fails to make any monthly payment to the Company within ten (10) calendar days of the due date for such payment, then the Company shall provide written notice to Executive, at his last known address, of such failure. If payment is not received within ten (10) calendar days from the date of said written notice, then the Company shall have the right to take possession of the automobile. Executive shall return such automobile to the Company in good condition, reasonable wear and tear excepted, on or before January 30, 2006. From the Effective Date of this Agreement through January 30, 2006, Executive shall be responsible for maintaining insurance coverage on the automobile with the same coverages and policy limits as existed as of the Date of Resignation, and name the Company as a named insured.
