With respect to any litigation and claims that are Excluded Liabilities, Buyer shall render all reasonable assistance that Seller may request in defending such litigation or claim and shall make available to Seller’s personnel most knowledgeable about the matter in question. If after the Closing Buyer (or any Affiliate or creditor of Buyer) shall receive any payment or revenue that belongs to Seller pursuant to this Agreement, Buyer shall promptly remit or caused to be remitted the same to Seller, without set-off or deduction of any kind or nature.

7.6. Calpine Marks. The Calpine Marks may appear on some of the Acquired Assets, including on signage.

7.7. Employee and Benefits Matters

(a) Intent to Employ. Buyer shall have the right at least five (5) Business Days after the entry of the Sales Order on the Bankruptcy Court’s docket to interview the Employee, and shall then notify Seller at least thirty (30) days prior to the Closing Date (or such shorter period as available) whether Buyer intends to cause Employee to be employed by it or its Affiliate. If Buyer elects to so employ Employee (hereinafter referred to as the “Accepting Employee“), such employment offer shall be at the same or substantially similar position.

However, employment will be contingent upon the Accepting Employee’s passing of a pre-employment physical, drug test, drivers license and background check and Employee’s executing of such agreements dealing with confidentiality, conflicts of interest and other matters as Buyer shall require. Nothing herein shall prevent Seller or its Affiliates from offering employment to Employee if Buyer elects not to employ Employee pursuant to the foregoing.

(b) Employment Offer. Such offer of employment shall be at the same base salary applicable to the Accepting Employee as of October 12, 2007 and Buyer shall not reduce such base salary during the 12-month period following the Closing so long as Employee is employed during such period. Buyer also agrees, or shall cause its applicable Affiliate, to provide the Accepting Employee and his covered dependents with welfare and retirement benefits that are the same as those for the employees of Buyer or its Affiliate. Accepting Employee’s employment with Buyer or its Affiliate, as the case may be, will be “at-will” and nothing contained in this Agreement or any other communication shall constitute a contract of employment and Employee shall not be a third party beneficiary of this Agreement.

(c) Benefit Plans. Accepting Employee will be enrolled in Buyer’s, or its applicable Affiliate’s, benefit and retirement plan(s) on the first day of employment. Benefits will be effective on the date specified in the official plan documents. To the extent permitted under HIPAA law and Buyer’s, or its applicable Affiliate’s, welfare benefit plans, Buyer shall , or cause its Affiliate, to waive pre-existing condition requirements, evidence of insurability provisions, waiting period requirements or any similar provisions under any welfare benefit plans maintained for the Accepting Employee after the Closing Date.

(d) Welfare Benefit Claims. Claims of the Accepting Employee and his eligible beneficiaries and dependents for medical, dental, prescription drug, life insurance, Worker’s Compensation, and/or other welfare benefits (“Welfare Benefits“) that are incurred before the Closing Date shall be the sole responsibility of Seller and Seller’s welfare benefit plans. Seller shall provide any COBRA or other notices required under Seller’s welfare benefit and retirement plans.
