                                   ARTICLE I

                                 REIMBURSEMENT

         SECTION 1.01 AGREEMENT TO REIMBURSE GUARANTOR.  (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

                 (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.

                                   ARTICLE II

                   REPRESENTATIONS, WARRANTIES AND COVENANTS

         merger or consolidation, nor sell, transfer, lease or otherwise
         dispose of all or any substantial part of its property, assets or
         business unless the surviving, continuing or resulting corporation (if
         not a Borrower) or the corporation that purchases, leases or otherwise
         acquires all or substantially all of the property, assets or business
         of such Borrower (the "Surviving Company") is a solvent corporation
         organized under the laws of the United States of America or any
         jurisdiction thereof and expressly and unconditionally assumes the due
         and punctual performance of all obligations of such Borrower hereunder
         and under the Security Documents, by an instrument in writing

         Borrower) shall, prior to or simultaneously with such merger,
         consolidation, sale, transfer, lease or other disposition, take all
         such actions and execute and deliver all such agreements, documents
         and instruments necessary to continue and maintain the perfection of
         the liens and security interests under and pursuant to the Security
         Documents for the benefit of the Guarantor and at least the same
         rights with respect to the security interests in the Collateral which
         the Guarantor had immediately prior to such transaction.  Nothing in
         this clause (b) shall constitute a release of or an agreement to
         release any security interests created by any Security Document.  All
         liens and security interests under the Security Documents shall
         survive all such transactions.
