Amended and Restated Credit Agreement.

          SECTION 4.3 Government Approval, etc. No material authorization or
approval or other action by, and no material notice to or filing with, any
Governmental Authority or other Person (other than those (x) that have been, or
on the Amendment Effective Date, will be, or, in the case of Filing Statements
delivered on the Amendment Effective Date, will be within 10 days after the
Amendment Effective Date, duly obtained or made and which are, or on the
Amendment Effective Date will be, or, in the case of Filing Statements delivered
on the Amendment Effective Date, will be within 10 days after the Amendment
Effective Date, in full force and effect and (y) that are contemplated or
required to be made after the Amendment Effective Date in accordance with the
terms of the Loan Documents and the Transactions Documents) is required for (i)
the due execution, delivery or performance by any Obligor of any Loan Document
to which it is a party or (ii) the due execution, delivery and/or performance by
any Obligor of the Transactions Documents to which each is a party, or (iii) the
conduct of the business of the U.S. Borrower and its Subsidiaries as currently
conducted following the Amendment Effective Date.

          SECTION 4.4 Validity, etc. This Amendment and the Second Amended and
Restated Credit Agreement constitute legal, valid and binding obligations of
Holdings and the Borrowers enforceable in accordance with their terms (except,
in any case, as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights generally
and by principles of equity).

          SECTION 4.5 Liens Unimpaired. After giving effect to this Amendment,
neither the modification of the Original Credit Agreement effected pursuant to
this Amendment nor the execution, delivery, performance or effectiveness of this
Amendment

          (a) impairs the validity, effectiveness or priority of the Liens
     granted pursuant to any Loan Document (as such term is defined in the
     Original Credit Agreement), and such Liens continue unimpaired with the
     same priority to secure repayment of all Obligations, whether heretofore or
     hereafter incurred; or

                                      -10-
<PAGE>
          (b) requires that any new filings be made or other action taken to
     perfect or to maintain the perfection of such Liens other than the actions
     required by Section 7.1.11 of the Second Amended and Restated Credit
     Agreement.

          SECTION 4.6 Solvency. On the Amendment Effective Date, after giving
effect to this Amendment and the Transactions, each of Holdings and each other
Obligor (taken together) are Solvent.

          SECTION 4.7 Stock Purchase Agreement. All representations and
warranties made by Holdings and, to the knowledge of Holdings and its
Subsidiaries, each other party to the Stock Purchase Agreement were true and
correct in all respects as of the date such representations and warranties were
made, and, as of the date hereof, no default has occurred and is continuing
under the Stock Purchase Agreement, except to the extent any such default or any
failure of any such representation and warranty to be true and correct could,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change.

          SECTION 4.8 No Default. Both immediately before and after giving
effect to this Amendment, no Default has occurred and is continuing as of the
Amendment Effective Date.

          SECTION 4.9 Accuracy of Information. None of the factual information
heretofore or contemporaneously furnished in writing to any Agent or any Lender
by or on behalf of any Obligor in connection with this Amendment or any other
Loan Document or any transaction contemplated hereby or thereby (including the
Transactions), taken as a whole, contains any untrue statements of material
fact, or omits to state any material facts necessary in either case to make such
information taken as a whole not materially misleading in light of the
circumstances under which such information was provided and no other factual
information hereafter furnished in connection with this Amendment or any other
Loan Document by or on behalf of any Obligor, or to any Agent or any Lender will
contain any untrue statements of material fact or will omit to state any
material facts in either case necessary to make such information taken as a
whole not materially misleading on the date as of which such information is
dated or certified in light of the circumstances under which such information
was provided. Notwithstanding the foregoing, all financial projections that have
been or are hereafter made available to any Lender or any of the Agents by
Holdings or any of its Subsidiaries or any of their respective representatives
in connection with the transactions contemplated hereby (the "Projections")
(including the Projections included in the bank memorandum furnished to the
Lenders with respect to the Borrowers and the other Obligors and the pro forma
balance sheet) have been or, in the case of the Projections made available after
the date hereof, will be prepared in good faith based upon assumptions believed
by Holdings and its Subsidiaries to be reasonable at the time such assumptions
were made (it being recognized by each of the Lenders and the Agents, however,
that projections as to future events are not to be viewed as facts and that the
actual results during the period or periods covered by the Projections will
probably differ from the projected results and such differences may be
material).

          SECTION 5.1 No Other Amendments; References to the Credit Agreement.
Other than as specifically provided herein or in the Second Amended and Restated
Credit Agreement, this Amendment shall not operate as a waiver or amendment of
any right, power or privilege of the Lenders under (and as defined in) the
Original Credit Agreement or any other Loan Document (as such term is defined in
the Original Credit Agreement) or of any other term or condition of the Original
Credit Agreement or any other Loan Document (as such term is defined in the
Original Credit Agreement) nor shall the entering into of this Amendment
preclude the Lenders from refusing to enter into any further waivers or
amendments with respect to the Second Amended and Restated Credit Agreement. All
references to the Original Credit Agreement in any document, instrument,
agreement, or writing shall from and after the Amendment Effective Date be
deemed to refer to the Second Amended and Restated Credit Agreement, and, as
used in the Second Amended and Restated Credit Agreement, the terms "Agreement,"
"herein," "hereafter," "hereunder," "hereto" and words of similar import shall
mean, from and after the Amendment Effective Date, the Second Amended and
Restated Credit Agreement.

          SECTION 5.2 Headings. The various headings of this Amendment are
inserted for convenience only and shall not affect the meaning or interpretation
of this Amendment or any provisions hereof.

          SECTION 5.3 Execution in Counterparts. This Amendment may be executed
by the parties hereto in several counterparts, each of which shall be deemed to
be an original and all of which shall constitute together but one and the same
agreement.

          SECTION 5.4 Expenses. The Borrowers agree to pay promptly (and in any
event on the Closing Date) after presentation of an invoice therefor all
reasonable out-of-pocket expenses of the Agents (including the reasonable fees
and out-of-pocket expenses of one counsel to the Agents (and of local counsel,
if any, who may be retained by such counsel)) in connection with the
preparation, negotiation, execution and delivery of this Amendment, the Second
Amended and Restated Credit Agreement, each other Loan Document and the
documents and transactions contemplated hereby, including the reasonable fees
and disbursements of Cahill Gordon & Reindel LLP, counsel for the Agents.

          SECTION 5.5 Cross-References. References in this Amendment to any
Article or Section are, unless otherwise specified or otherwise required by the
context, to such Article or Section of this Amendment.

          SECTION 5.6 Cooperation; Other Documents. At all times following the
execution of this Amendment, the Obligors party hereto shall execute and deliver
to the Lenders and the Agents, or shall cause to be executed and delivered to
the Lenders and the Agents, and shall do or cause to be done all such other acts
and things as the Lenders and the Agents may reasonably deem to be necessary or
desirable to assure the Lenders and the Agents of the benefit of this Amendment
(including the Second Amended and Restated Credit Agreement), the other Loan
Documents and each other document relating to this Amendment.
