The Borrowers hereby acknowledge, confirm, and agree that as of the close of business on April 19, 2005, (a) the Borrowers are not indebted to the Lenders in respect of the Revolving Loans and (b) the Borrowers are indebted to the Lenders in respect of the Letters of Credit in the principal amount of approximately $13.6 million (subject to currency exchange fluctuations and reductions for any Letters of Credit which are drawn and reimbursed after April 20, 2005). Each of the Borrowers and the other Loan Parties represents, warrants and agrees that except for the Specified Defaults, no other Defaults or Events of Default have occurred which remain continuing as of the date hereof.

(a) Subject to the satisfaction of the conditions precedent set forth in Section 12 hereof, the Agents and Lenders hereby waive the Specified Defaults. The foregoing waiver shall (i) not be deemed a waiver of any other Default or Event of Default which has occurred, exists or hereafter may occur under the Credit Agreement or any other Loan Document; (ii) not be deemed to establish a custom or course of dealing among the Administrative Agent, Collateral Agent, Lenders, Borrowers other Loan Parties or any of them; and (iii) expire on May 13, 2005, if by such date Borrowers have failed to (w) fully comply with Section 6.24 of the Credit Agreement, (x) deliver the certification required by Section 5.01(j) of the Credit Agreement, (y) deliver the financial information required under Sections 5.01(a), (c) and (d) of the Credit Agreement, and (z) take the actions required under Sections 5.10 and 6.14 of the Credit Agreement and Section 6.19 of the Security Agreement in connection with the ISRON Acquisition (as defined on Exhibit A).

Holdings intends to cause ICM to liquidate, merge into existing Subsidiary Guarantors or otherwise dispose of the ICM Foreign Subs (the “Disposition”). Accordingly, subject to the satisfaction of the conditions precedent set forth in Section 12 hereof, the Agents and Lenders hereby waive the requirement that the ICM Foreign Subs become Subsidiary Guarantors and grant a Lien on their assets and that any Company pledge of any securities of, or existing intercompany notes with, the ICM Foreign Subs; provided, however, if the Disposition is not consummated by June 15, 2005, each of the ICM Foreign Subs shall be required to become, and shall have become, Subsidiary Guarantors to the extent required by the Credit Agreement.

Notwithstanding anything to the contrary contained in the Credit Agreement or any other Loan Document, the Agent may extend the time period set forth in clause (a)(iii)(w) of this Section 3 in its sole and absolute discretion; provided, however, any such extension shall
