		 	 INCREMENTAL TERM LOAN ASSUMPTION AGREEMENT, AMENDMENT NO. 2 AND CONSENT dated as of April 28, 2006 (this “Assumption

 A. The Borrower has requested that the persons set forth on Schedule I hereto (the
“Incremental Term Lenders”) make Incremental Term Loans to the Borrower pursuant to Section 2.24 of the Credit Agreement, the proceeds of which will be used to refinance the subordinated debentures
described in clause (a) of the definition of “Shareholder Notes” set forth in Section 1.01 of the Credit Agreement in an aggregate outstanding principal amount of $100,000,000 (the “Subordinated
Debentures”). 
 B. The Incremental Term Lenders are willing to make Incremental Term Loans to the Borrower on the
Amendment No. 2 Effective Date (as defined below), on the terms and subject to the conditions set forth herein and in the Credit Agreement. 
 C. Additionally, the Borrower has requested (i) that the Required Lenders consent to the refinancing of the Subordinated Debentures with the proceeds of the Incremental Term Loans made pursuant to this Assumption Agreement and
Amendment and (ii) certain amendments to the Credit Agreement as set forth herein. 
 Accordingly, in consideration of the mutual
agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows: 
 SECTION 1. Defined Terms; Interpretation; Etc. Capitalized terms used and not defined herein shall have the meanings assigned to such terms in the Credit Agreement. The rules of
construction set forth in Section 1.02 of the Credit Agreement shall apply equally to this Assumption Agreement and Amendment. This Assumption Agreement and Amendment shall be a “Loan Document” and, to the extent it relates to the
making of Incremental Term Loans, an “Incremental Term Loan Assumption Agreement” for all purposes of the Credit Agreement and the other Loan Documents. 
 SECTION 2. Incremental Term Loans. (a) Each Incremental Term Lender hereby agrees to make an Incremental Term Loan to the Borrower on the Amendment No. 2 Effective Date in a
principal amount equal to the Incremental Term Loan amount set forth next to such Incremental Term Lender’s name on Schedule I attached hereto. All such Incremental Term Loans shall constitute “Term Loans” for all purposes of the
Credit Agreement and the other Loan Documents. 

 (b) The proceeds of the Incremental Term Loans are to be used by the Borrower solely to refinance the
Subordinated Debentures. 
 SECTION 3. Conditions Precedent to Incremental Term Loans. The obligation of the
Incremental Term Lenders to make Incremental Term Loans hereunder shall be subject to the satisfaction of the following conditions precedent: 
 (a) On the Amendment No. 2 Effective Date, each of the conditions set forth in paragraphs (b) and (c) of Section 4.01 of the Credit Agreement shall be satisfied and the Administrative Agent shall have received a
certificate to that effect dated as of the Amendment No. 2 Effective Date and executed by a Financial Officer of the Borrower. 
 (b)
The Administrative Agent shall have received (with sufficient copies for each Incremental Term Lender) such legal opinions, board resolutions and other closing certificates and documentation as shall be reasonably required by the Incremental Term
Lenders, in each case consistent with those delivered on the Closing Date under Section 4.02 of the Credit Agreement. 
 (c) The
Administrative Agent shall have received a certificate, dated the Amendment No. 2 Effective Date and executed by a Financial Officer of the Borrower, confirming that the Borrower will be in pro forma compliance with the financial covenants set
forth in Sections 6.10, 6.11 and 6.12 of the Credit Agreement as of and for the most recently ended period of four consecutive fiscal quarters for which financial statements have been delivered to the Administrative Agent pursuant to
Section 5.04 of the Credit Agreement (assuming for the purposes of Section 6.12 of the Credit Agreement that such transactions occurred at the end of such period and for the purposes of Sections 6.10 and 6.11 of the Credit Agreement that
such transactions occurred at the beginning of such period) after giving effect to the making of the Incremental Term Loans and the application of the proceeds therefrom. 
 (d) The Administrative Agent shall have received all fees and other amounts due and payable on or prior to the Amendment No. 2 Effective Date, including, to the extent invoiced, reimbursement or payment of all
out-of-pocket expenses required to be reimbursed or paid by the Borrower hereunder or under any other Loan Document. 
 SECTION 4.
Amendments to Credit Agreement. Effective as of the Amendment No. 2 Effective Date: 
 (a) Section 1.01
of the Credit Agreement is hereby amended by adding the following defined terms in appropriate alphabetical order: 
 “Amendment No. 2” shall mean the Incremental Term Loan Assumption Agreement, Amendment No. 2 and Consent related to this Agreement dated as of April 28, 2006.

 “Amendment No. 2 Effective Date” shall have the meaning assigned to such term in Amendment
No. 2. 
 “Specified Ratings Condition” means the Term Loans shall have received a rating of Ba3
or higher from Moody’s and BB- or higher from S&P, in each case with no negative outlook (the “Specified Ratings”); provided that 

  

 2 

 
the Specified Ratings Condition shall only remain satisfied for so long as each of the Specified Ratings shall be maintained in effect. 
 (b) The definition of the term “Applicable Percentage” set forth in Section 1.01 of the Credit
Agreement is hereby amended and restated in its entirety as follows: 
 ““Applicable Percentage”
shall mean, for any day, (a) with respect to any Eurodollar Term Loan or ABR Term Loan, as the case may be, the applicable percentage set forth below in the first table under the caption “Eurodollar Spread—Term Loans” or
“ABR Spread—Term Loans”, as the case may be, based upon the Leverage Ratio as of the relevant date of determination, (b) with respect to any Swingline Loan, the applicable percentage set forth below in the second table under the
caption “ABR Spread— Revolving Loans”, based upon the Leverage Ratio as of the relevant date of determination, and (c) with respect to any Eurodollar Revolving Loan or ABR Revolving Loan, as the case may be, the applicable
percentage set forth below in the second table under the caption “Eurodollar Spread—Revolving Loans” or “ABR Spread—Revolving Loans”, as the case may be, based upon the Leverage Ratio as of the relevant date of
determination: 
  

							
	 Leverage Ratio
	  	Eurodollar Spread – Term
Loans	 	 	ABR Spread - Term
Loans	 
	Category 1	  			 		
	Greater than 2.75 to 1.00	  	2.25	%	 	1.25	%
			
	Category 2	  			 		
	Greater than 2.00 to 1.00, but less than or equal to 2.75 to 1.00	  	2.00	%	 	1.00	%
			
	Category 3	  			 		
	Less than or equal to 2.00	  	1.75	%	 	0.75	%

 provided that Category 3 (as set forth in the table above) will only apply upon the
satisfaction of the Specified Ratings Condition (as evidenced by a certificate of a Responsible Officer of the Borrower delivered to the Administrative Agent) and for so long as the Specified Ratings Condition shall remain satisfied. If the rating
system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Term Lenders shall negotiate in good faith to amend the definition of the
term Specified Ratings Condition to reflect such changed rating system, or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Percentage with respect to any Eurodollar Term Loan
or ABR Term Loan shall be determined based on the ratings most recently in effect.

	Less than or equal to 2.25 to 1.00	  	1.75	%	 	0.75	%

 Each change in the Applicable Percentage resulting from a change in the Leverage Ratio shall be
effective with respect to all Loans and Letters of Credit outstanding on and after the date of delivery to the Administrative Agent of the financial statements and certificates required by Section 5.04(a) or (b) and Section 5.04(c),
respectively, indicating such change until the date immediately preceding the next date of delivery of such financial statements and certificates indicating another such change. Notwithstanding the foregoing, until the Borrower shall have delivered
the financial statements and certificates required by Section 5.04(b) and Section 5.04(c), respectively, covering a period of at least six full months following the Closing Date, the Leverage Ratio shall be deemed to be in Category 1 (as
set forth in the applicable table above) for purposes of determining the Applicable Percentage. In addition, (a) at any time during which the Borrower has failed to deliver the financial statements and certificates required by
Section 5.04(a) or (b) and Section 5.04(c), respectively, or (b) at any time after the occurrence and during the continuance of an Event of Default, the Leverage Ratio shall be deemed to be in Category 1 (as set forth in the
applicable table above) for purposes of determining the Applicable Percentage.”

	 	(ii)	by deleting the word “and” before clause (a)(x) therein and substituting a comma therefor; and

 “(c) If at the time of any Equity Issuance the Leverage Ratio (after giving effect to such Equity Issuance and the proposed use of
proceeds thereof) would be greater than or equal to 2.75 to 1.00, the Borrower shall, substantially simultaneously with (and in any event not later than the third Business Day next following) the occurrence of such Equity Issuance, apply 50% (or
such lesser percentage as shall be necessary to reduce such Leverage Ratio below 2.75 to 1.00) of the Net Cash Proceeds therefrom to prepay outstanding Term Loans in accordance with Section 2.13(f); provided, however, that so long as no
Event of Default has occurred and is continuing, no prepayment shall be required from the Net Cash Proceeds of Additional Sponsor Capital.”
