4. Consent to ICS Program. The Borrowers have notified the Administrative Agent and the Required Lenders that one or more Companies plan to deposit funds with one or more Lenders that will be part of an insured cash sweep or similar program that ensures such funds are FDIC insured (an “ICS Program”). The Borrowers are requesting that the Administrative Agent and the Required Lenders consent to the Companies entering into ICS Programs. The Administrative Agent and the Required Lenders hereby consent to the Companies entering into ICS Programs, and this Amendment shall serve as evidence of such consent, on the conditions that (a) any such ICS Program is with a Lender, who shall have executed a Control Agreement in form and substance satisfactory to the Administrative Agent with respect thereto, (b) the aggregate amount of deposits of the Companies through ICS Programs shall not exceed fifty percent (50%) of all cash and Cash Equivalents held by the Companies, (c) after giving effect to this Amendment, no Default or Event of Default shall exist under the Credit Agreement or any other Loan Document, and (d) upon the occurrence and during the continuance of an Event of Default, the Administrative Agent or the Required Lenders may require any such cash and Cash Equivalents held in an ICS Program to be moved out of (and no longer be subject to) such ICS Program. Except as otherwise expressly specified in this Amendment, the Credit Agreement shall each remain in full force and effect and shall be unaffected hereby. The consent granted herein (a) is not intended to, nor shall it, establish any course of dealing among the Borrowers, the Administrative Agent and the Lenders that is inconsistent with the express terms of the Credit Agreement, and (b) shall not operate as a waiver or amendment of any other right, power or remedy of the Administrative Agent and the Lenders under the Credit Agreement. The consent requested by the Borrowers and granted by the Administrative Agent and the Required Lenders hereunder relates solely to the items set forth in this Section 4. No further consent has been requested or granted. Each Lender hereby acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender, made its own credit analysis and decision with respect to the holding of funds in ICS Programs by the Companies as consented to herein.

5. Closing Deliveries. Concurrently with the execution of this Amendment, the Borrowers shall:

7. Waiver and Release. The Borrowers, by signing below, hereby waive and release the Administrative Agent, and each of the Lenders, and their respective directors, officers, employees, attorneys, affiliates and subsidiaries (each, a “Released Person”), from any and all claims, offsets, defenses and counterclaims of any kind or nature, absolute and contingent (each, a “Claim”), of which the Borrowers are aware or should be aware on the date of this Amendment, for or because of any matter or thing done, omitted or suffered to be done or omitted by any of the Released Persons that both (a) occurred prior to or on the date of this Amendment and (b) is on account of or in any way concerning, arising out of or founded upon the Credit Agreement or any other Loan Document; provided however, that the above release shall not apply to any Claim due to gross negligence or willful misconduct of any Released Person; provided, further, such waiver and release being with full knowledge and understanding of the circumstances and effect thereof and after having consulted legal counsel with respect thereto.
