(a) Reimbursement. The Borrowers absolutely and unconditionally agree, jointly and severally, to reimburse the Guarantor immediately on demand for each payment made by the Guarantor following a written demand under the Guaranty ("Guaranty Payments") by either or both of the Agent or the Paying Agent by paying to the Guarantor as provided herein an amount equal to the amount of such Guaranty Payment (a "Reimbursement Payment"). Payment shall be made by the Borrowers upon receipt of written demand for payment from the Guarantor setting forth the amount due and owing but without any need of further documentation. A copy of such written demand for payment shall be given to OHM addressed to "Independent Directors" in the manner set forth in Section 5.08 hereof for notice to either Borrower. Any defects or omissions regarding such copy of written demand for payment to "Independent Directors" will not terminate or modify in any way the Borrowers' obligations pursuant to this Agreement. Each Reimbursement Payment to be made by the Borrowers hereunder shall be made in lawful money of the United States of America by wire transfer of immediately available funds to Mellon Bank, N.A. Pittsburgh, Pennsylvania, A.B.A. Number 043000261, for credit to the account of the Guarantor, Account Number: 1979409 (or to such other bank or account as the Guarantor may specify in writing). If the Borrowers fail to pay any amount payable by the Borrowers hereunder when due (including, without limitation, accrued but unpaid interest), such amount shall bear interest (computed on the basis of a 360 day year and actual days elapsed) from the due date thereof until paid in full, at a rate per annum equal to the lesser of (i) the sum of the Prime Rate from time to time in effect plus 2% or (ii) the maximum non-usurious rate permitted by applicable law, payable on demand. (b) Obligations Absolute. The obligations of the Borrowers under this Agreement shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances whatsoever irrespective of: (i) any lack of validity or enforceability of any of the Obligations, the Credit Agreement, this Agreement, any of the Security Documents or any of the Transaction Documents; (ii) the absence of any attempt by, or on behalf of, the Guarantor to collect or to take any other action to enforce, all or any part of the obligations hereunder whether from or against either Borrower, any other guarantor of the Obligations or any other person; 2 3 (iii) the election of any remedy by, or on behalf of, the Guarantor with respect to all or any part of the obligations of the Borrowers hereunder; (iv) the waiver, consent, extension, forbearance or granting of any indulgence by, or on behalf of, the Lenders or the Guarantor with respect to any provision of any of the Transaction Documents; (v) any lack of validity or enforceability of, or any waiver or forbearance by or on behalf of the Guarantor, of the Guarantor's subrogation rights under or in connection with the Guaranty, the Intercreditor Agreement or the Transaction Documents; (vi) any amendment or waiver of or any consent to departure from all or any of the Transaction Documents, the Intercreditor Agreement, this Agreement or Security Agreements; (vii) the existence of any claim, set-off, defense or other rights which either Borrower may have at any time against the Agent, the Paying Agent, any Lender or the Guarantor (other than the defense of payment to the Guarantor in accordance with the terms of this Agreement), or any other person or entity, whether in connection with this Agreement, the Security Documents, the Transaction Documents, the Intercreditor Agreement or any unrelated transaction; (viii) any statement or any other document presented under the Guaranty proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; (ix) the failure of the Guarantor to take any steps to perfect and maintain its security interest in or to preserve its rights to, any security or collateral for the obligations of the Borrowers hereunder; (x) the election by, or on behalf of, the Guarantor in any proceeding instituted under Chapter 11 of Title 11 of the United States Code (11 U.S.C. 101 et. seq.) (the "Bankruptcy Code"), of the application of Section 1111(b)(2) of the Bankruptcy Code; (xi) the disallowance under Section 502 of the Bankruptcy Code, of all or any portion of the claims of the Guarantor for payment of all or any part of the obligations of the Borrowers hereunder or any expenses in connection herewith; (xii) the invalidity, unenforceability or avoidance of any obligation of the Guarantor to make any payment to the Guaranteed Parties under the Guaranty or the failure of or waiver by the Guarantor to contest, object to or otherwise challenge any request by any Lender for the Guarantor to make any payment under the Guaranty; or 3 4 (xiii) any other circumstance which might otherwise constitute a legal or equitable discharge or defense of either Borrower. (c) Liability of the Guarantor. Each Borrower assumes all risks of the acts or omissions of the Agent, the Paying Agent or any Lender with respect to its use of the Guaranty. Neither the Guarantor nor any of its officers or directors shall be liable or responsible for: (i) the use which may be made of the Guaranty or for any acts or omissions of the Agent, the Paying Agent or any Lender or any transferee in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) any other circumstances whatsoever in making or failing to make payment under the Guaranty. The Borrowers acknowledge and agree that the Guarantor shall not in any way be responsible and shall not bear any liability for any failure by or on behalf of any Lender to extend credit or provide funds to either Borrower or for any other action or inaction of any Lender under and pursuant to the Credit Agreement or otherwise. Except as otherwise expressly provided in this Agreement or any other agreement between or among the parties hereto, the Guarantor shall have no liability to the Borrowers (i) on account of making payment upon receipt of a demand under the Guaranty or (ii) except for damages arising out of the gross negligence or willful misconduct of the Guarantor, with respect to any other matters pertaining hereto. (d) Subrogation. In addition to, but not in limitation of, all of the rights, interest and remedies of the Guarantor under this Agreement, the Security Documents and the Intercreditor Agreement, each Borrower acknowledges and agrees that the Guarantor shall upon and to the extent of any payment made by the Guarantor pursuant to a claim made under the Guaranty be subrogated to, and a beneficiary of, all of the rights and interests of the Lenders, the Agent and the Paying Agent under and to the Credit Agreement, the Transaction Documents and any collateral or security granted by either Borrower thereunder. SECTION 1.02 PAYMENT OF INTEREST AND FEES. If any sum becomes payable pursuant to this Agreement on a day which is not a Business Day, the date for payment thereof shall be extended, without penalty, to the next succeeding Business Day, and such extended time shall be included in the computation of interest and fees. SECTION 1.03 NO DEDUCTIONS. All sums payable by the Borrowers hereunder, whether of Reimbursement Amount, interest, expenses or otherwise, shall be paid in full, without any deduction or withholding whatsoever. In the event that either Borrower is compelled by any present or future law, rule or regulation to make any such deduction or withholding, such Borrower shall nevertheless pay the Guarantor such amounts as will result in the receipt by the Guarantor of the sum it would have received had no such deduction or withholding been required to be made. In furtherance of and in addition to the foregoing, each of the Borrowers hereby waives any and all rights, whether now existing or from time to time arising, to set off and apply any and 4 5 all trade deposits or other accounts of the Guarantor of any kind whatsoever at any time held by either Borrower and any other indebtedness at any time owing by the Guarantor to or for the credit or the account of either Borrower against any and all of the obligations of either Borrower now or hereafter owing under this Agreement.
