2. Conversion of Term Loan A. On March 31, 2005, after giving effect to the
repayments of the Term Loan A provided in Sections 2.09(c) and (d) (as amended
pursuant to Section 1 above), the aggregate Outstanding Amount of the Term Loan A as of such date
(the TLA Outstanding Amount) shall automatically be deemed to have been converted into an equal
Outstanding Amount of the Term Loan B, such that the Outstanding Amount of the Term Loan B shall be
increased by the TLA Outstanding Amount, and (b) each Term Loan A Lender holding a portion of the
TLA Outstanding Amount as of such a date shall (if it is not already also a Term Loan B Lender)
automatically become a Term Loan B Lender, and (c) the Pro Rata Term B Share of the Term Loan B of
each Term Loan B Lender shall be equal to the percentage computed (in each case after giving effect
to the conversions described in subsections (a) and (b) above) as (x) such Term Loan B Lenders
Outstanding Amount of the Term Loan B divided by (y) the Outstanding Amount of the Term
Loan B. After giving effect to this Section 2, the Outstanding Amount of the Term Loan A
shall be $0, and the Outstanding Amount of the Term Loan B shall be $83,968,550 less the principal
amount of any optional prepayments that may have been made between the date of this Agreement and
March 31, 2005. The parties hereto acknowledge that the Term Loan A Advance Expiration Date has
occurred, the Borrowers ability to request further Loans under Term Loan A Facility has expired,
and the Term Loan A Facility shall be deemed to have been paid in full and terminated upon the
effectiveness of the provisions of this Section 2. Nothing in this Section 2 or
otherwise in this Agreement shall increase the Outstanding Amount of the Term Loan B of any Term
Loan B Lender that is not a Term Loan A Lender immediately prior to giving effect to this
Agreement. 3. Conditions Precedent. The effectiveness of this Agreement and the amendments to the
Credit Agreement herein provided are subject to the satisfaction of the following conditions
precedent: (a) The Administrative Agent shall have received each of the following documents or
instruments in form and substance reasonably acceptable to the Administrative Agent: (i) thirteen (13) original counterparts of this Agreement, duly executed by the
Borrower, the Administrative Agent, each Guarantor and the necessary Lenders,
together with all schedules and exhibits thereto duly completed; and (ii) such other documents, instruments, opinions, certifications, undertakings,
further assurances and other matters as the Administrative Agent shall reasonably
require; and (b) all fees and expenses payable to the Administrative Agent and the Lenders
(including the fees and expenses of counsel to the Administrative Agent) accrued to date
shall have been paid in full. -4-

Agreement and the other Loan Documents, including without limitation all Persons who became
Subsidiaries or were otherwise required to become Guarantors after the Closing Date, and
each of such Persons has become and remains a party to Guaranty as a Guarantor; (d) This Agreement has been duly authorized, executed and delivered by the Borrower and
Guarantors party hereto and constitutes a legal, valid and binding obligation of such
parties, except as may be limited by general principles of equity or by the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium or similar law affecting
creditors rights generally; and (e) After giving effect to this Agreement, no Default or Event of Default has
occurred and is continuing. 6. Entire Agreement. This Agreement, together with all the Loan Documents
(collectively, the Relevant Documents), sets forth the entire understanding and agreement
