6.2 Release. The Obligors party hereto and their respective successors, assigns, and subsidiaries, on the one hand (collectively, the “Releasors”), and the Agent, the Lenders and their respective Related Parties, on the other hand, hereby agree to eliminate any possibility that any

5

past or current conditions, acts, omissions, events, circumstances or matters would impair or otherwise adversely affect any of the rights, interests, contracts, collateral security or remedies of the Agent and the Lenders on or prior to the date hereof. Therefore, as a material inducement to the Agent and the Lenders to enter into this Waiver, the Releasors hereby waive, release, and discharge the Agent, each Lender and their respective Related Parties from any and all claims, demands, actions or causes of action that the Releasors may have that arise out of or in any way relate to any action that such Lender or Agent, in their capacities as such, or any such Related Party may have taken or omitted to take on or before the date hereof with respect to the Obligors, the Chapter 11 Cases, any Credit Document, or any other document, instrument, dealing or other matter connected with any Credit Document.
