NOW, THEREFORE, in consideration of good and valuable consideration, the receipt of which is hereby acknowledged, and intending to be legally bound, the parties hereto hereby agree as follows:

(a) Consent to Assignment. The Consenting Parties (i) acknowledge that Collateral Agent and the Lenders have entered into the Credit Agreement and have made the Loans (ii) consent in all respects to the pledge and assignment to Collateral Agent of all of the Borrower’s right, title and interest (subject to Borrower’s obligations) in, to and under the Assigned Agreements pursuant to the Security Agreement and the pledge and collateral assignment of shares in the Borrower pursuant to the Pledge Agreement and (iii) acknowledge the right, but not the obligation, of Collateral Agent or Collateral Agent’s designee, in the exercise of Collateral Agent’s rights and remedies under the Security Agreement, to make all demands, give all notices, take all actions and exercise all rights of the Borrower (subject to Borrower’s obligations) in accordance with the Assigned Agreements, and agree that in such event the Consenting Parties shall continue to perform their respective obligations under the Assigned Agreements.

(b) Substitute Owner. The Consenting Parties agree that, if Collateral Agent notifies the Consenting Parties that an event of default under the Credit Agreement has occurred and is continuing and that Collateral Agent has exercised its rights (i) to have itself or its designee, reasonably acceptable to Consenting Party, substituted for the Borrower under one or more of the Assigned Agreements or (ii) to sell, assign, transfer or otherwise dispose of one or more of the Assigned Agreements to a third party, reasonably acceptable to each Consenting Party party thereto, then Collateral Agent, Collateral Agent’s designee or such third party (a “Substitute Owner”) shall be substituted for the Borrower under each such Assigned Agreement and, in such

2

event, each Consenting Party party thereto will continue to perform its obligations under each such Assigned Agreement in favor of the Substitute Owner and the Substitute Owner will perform and fulfill all of the obligations of Borrower under each such Assigned Agreement; provided that any Substitute Owner shall be deemed to be acceptable to each such Consenting Party if such Consenting Party does not object to such proposed Substitute Owner within fourteen (14) business days following delivery of written notice thereof to such Consenting Party. The proposed Substitute Owner shall promptly provide each such Consenting Party with all financial and commercial information reasonably requested by such Consenting Party in order to evaluate the proposed Substitute Owner’s ability to perform under the applicable Assigned Agreement(s). The failure of the proposed Substitute Owner to promptly provide each such Consenting Party with the requested financial and commercial information shall constitute reasonable grounds for such Consenting Party to object to the proposed Substitute Owner.

(c) Right to Cure. (i) The Consenting Parties shall not claim prevention or interference with performance of their respective obligations under the Assigned Agreements, nor shall any of the Consenting Parties exercise any right it may have under any of the Assigned Agreements, at law or in equity, to cancel, suspend or terminate such Assigned Agreement or any of its obligations under such Assigned Agreement, as the result of any default or other action or omission of the Borrower in the performance of any of its obligations under such Assigned Agreement, or upon the occurrence or non-occurrence of any event or condition under such Assigned Agreement that would immediately or with the passage of any applicable grace period or the giving of notice, or both, enable such Consenting Party to terminate or suspend its obligations or exercise any other right or remedy under such Assigned Agreement or under applicable law (hereinafter an “Assigned Agreement Default”), until it first gives prompt written notice of such Assigned Agreement Default to the Collateral Agent . The Senior Secured Parties shall have the same right to cure such Assigned Agreement Default as is available to the Borrower, and such cure period shall commence upon the Collateral Agent’s receipt of notice under this Section 1(c). If such Assigned Agreement Default is timely cured as required under the applicable Assigned Agreement in accordance with the time period provided for in this Section 1(c), the Consenting Party party to such Assigned Agreement will continue to perform its obligations under such Assigned Agreement.

(i) No cancellation, suspension or termination of an Assigned Agreement by a Consenting Party, or any other actions taken by a Consenting Party under an Assigned Agreement, shall be binding upon Collateral Agent without the notice and cure period specified in this Section 1(c). Any dispute that may arise under an Assigned Agreement notwithstanding, the Consenting Party shall continue performance under such Assigned Agreement and resolve any dispute without discontinuing such performance until the lapse of the notice and cure period specified in this Section 1(c).
