Severance Compensation. Except as otherwise provided in subparagraph 4(c), the Company will pay and provide the following as specified to Executive should his employment be terminated under any of the conditions described in paragraphs 1 through 3 which would make him eligible to receive them: (a) Base Severance Pay. (i) If circumstances exist so that if paragraph 1 or subparagraph 2(a) is applicable, Executive shall receive a cash payment equal to one year of Executive's base salary in effect on the date of this Agreement. (ii) If circumstances exist so that paragraph 3 is applicable, Executive shall receive a cash payment equal to the greater of (a) two weeks of Executive's base salary in effect on the date of this Agreement, per each full year and any fraction of year of Executive's combined service with the Company and the Successor subject to a minimum of twelve (12) weeks and a maximum of fifty-two (52) weeks of base salary regardless of Executive's actual service or (b) one year of Executive's base salary in effect on the date of this Agreement multiplied by a fraction the numerator of which equals the number of calendar days remaining from the date of Executive's termination by the Successor to the first calendar year anniversary of the Closing Date and the denominator equals 365 days. (b) Benefit Continuation Payment. Executive shall receive a cash payment equal to the cost which employee would be required to pay to acquire continuation coverage, pursuant to the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), 29 U.S.C. Sections 1161-1167, under the medical benefit plan which covered Executive immediately prior to his termination of employment for a period equal to the total number of weeks of base salary which the Executive is entitled to receive under subparagraph 4(a). (c) Retirement Benefit Improvements.

If the value or the effect of any item described in subparagraphs 4(c)(i) through (iv) cannot be paid from or provided through the Plan for any reason, as determined by the Plan Administrator in his judgment, then the value of such item(s) will be provided in an equivalent cash payment to the Executive. This payment shall equal the actuarial equivalent of the particular value or effect determined using the assumptions and methods then employed under the Plan to determine the lump sum equivalent of pensions payable under the Plan. Such calculations shall be made by the Plan Administrator and shall be final and conclusive. (d) Payment for Unvested Options. The Company shall pay Executive for any unvested options of the Company's shares at the rate of $6.84 per share for those shares covered by options awarded before August 1996 and $3.42 per share for those shares covered by options awarded during or after August 1996.
