CONVERSION OF EXISTING TERM LOANS AND ADDITIONAL TERM LOANS

SECTION 3.1 Agreement to Conversion of Existing Term Loans into New Term Loans.
On the terms and subject to the satisfaction (or waiver) of the conditions set
forth in Article IV hereof, each Converting Term Lender agrees that an aggregate
principal amount of its Existing Term Loans equal to the amount notified to such
Converting Term Lender by the Administrative Agent will be converted into New
Term Loans (the “Converted Term Loans”) as of the First Amendment Effective
Date.

SECTION 3.2 Agreement to Make Additional Term Loans. On the terms and subject to
the satisfaction (or waiver) of the conditions set forth in Article IV hereof,
each Additional Term Lender agrees to make Additional Term Loans equal to the

Term Loans) on the First Amendment Effective Date and shall be a “Lender” under
the Credit Agreement as of such date.

SECTION 3.3 Other Provisions. On the First Amendment Effective Date, the
Borrower shall apply the proceeds of the Additional Term Loans (if any),
together with available cash, to (i) prepay in full all Existing Term Loans,
other than Converted Term Loans, (ii) pay all accrued and unpaid interest on the
aggregate principal amount of the Existing Term Loans being so prepaid,
(iii) pay to each Existing Term Lender all amounts payable pursuant to
Section 4.11 of the Credit Agreement as a result of the prepayment of such

Lenders all indemnities, cost reimbursements and other Obligations then owed to
the Non-Converting Term Lenders under the Credit Agreement. The repayment of the
Existing Term Loans contemplated hereby constitutes a voluntary prepayment by
the Borrower pursuant to Section 4.1 of the Credit Agreement. Upon the First

aggregate principal amount of the New Term Loans will not exceed the aggregate
principal amount of the Existing Term Loans outstanding immediately prior to the
First Amendment Effective Date. Each of the parties hereto acknowledges and
agrees that the terms of this Amendment do not constitute a novation but,
rather, an amendment of the terms of a pre-existing Indebtedness and related
agreement, as evidenced by the Existing Credit Agreement.

--------------------------------------------------------------------------------

such representations and warranties shall be true and correct in all material

of credit to be made by it;

(c) no Default or Event of Default has occurred and is continuing on the date
hereof or after giving effect to the extensions of credit requested to be made
on the date hereof;

(d) this Amendment has been duly authorized, executed and delivered by the
Borrower and constitutes a legal, valid and binding obligation of the Borrower,
enforceable against it in accordance with its terms, except to the extent the
enforceability hereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors’ rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law); and

(e) the execution, delivery and performance by the Borrower of this Amendment,

same priority to secure repayment of all Obligations, whether heretofore or
hereafter incurred. Neither the modification of the Existing Credit Agreement

requires that any new filings be made or other action taken to perfect or to
maintain the perfection of such Liens. Under the foregoing circumstances, the
position of the Lenders with respect to such Liens, the Collateral (as defined
in the Existing Security Documents) in which a security interest was granted
pursuant to the Existing Security Documents, and the ability of the
Administrative Agent to realize upon such Liens pursuant to the terms of the
Security Documents have not been adversely affected in any
