 (b) Amendments to Section 3.01(b) of the Credit Agreement.
Section 3.01(b) of the Credit Agreement is hereby amended as follows: 
 (i) Clause (vii) is amended and
restated as follows: 
 “(vii) So long as any Term Loans remain outstanding, any Term Loan Lender may elect to decline
the entire portion of the prepayment of its Term Loans pursuant to Section 3.01(b) by delivery of a completed Notice of Election to the Administrative Agent by telecopy at least one Business Day prior to the applicable prepayment
date, in which case the aggregate amount of the prepayment that would have been applied to prepay Term Loans but was so declined shall be re-offered to those Term Loan Lenders under this Agreement who have initially accepted such prepayment
(such re-offer to be made to each such Term Loan Lender based on the percentage which such Term Loan Lender’s Term Loans represents of the aggregate Term Loans of all such Term Loan Lenders who have initially accepted such prepayment). In the
event of such a re-offer, the relevant Lenders may elect to decline in such Notice of Election all of the amount of such prepayment that is re-offered to them, in which case the aggregate amount of the prepayment that would have been applied to
prepay such Term Loans pursuant to such re-offer but was so declined shall be applied to repay Revolver Loans; provided that no reduction of the Revolver Commitments shall be required in connection with such prepayment. Any amounts
remaining following repayment of the Revolver Loans shall be returned to the Borrower. In the absence of delivery of a completed Notice of Election with respect to any prepayment at least one Business Day prior to the applicable prepayment date,
such Lender shall automatically be deemed to have accepted such prepayment and any re-offer in respect thereof.” 
 (c) Amendments to Article II of the Credit Agreement. Article II of the Credit Agreement is hereby amended by adding Section 2.12 as follows: 
 “Section 2.12 Increase in Commitments. 
  

	 	a)	Borrower Request. Borrower may by written notice to the Administrative Agent elect to request prior to the Termination Date, an increase to the existing Revolver Commitments
(an “Incremental Loan Commitment”) by an amount not in excess of $140,000,000; provided that the sum of the Incremental Loan Commitment and the amount of Revolver Loans repaid by the Borrower with the proceeds of a
Specified Note Offering declined by the Term Loan Lenders pursuant to Section 3.01(b)(vii) of this Agreement shall not exceed $200,000,000; provided, however that the limitation in the immediately preceding proviso shall cease to apply
45 business days after the date of the Amendment No. 1 and Agreement. Each such notice shall specify (i) the date (each, an “Increase Effective Date”) on which Borrower proposes that the increased or new Commitments
shall be effective, which shall be a date not less than 10 Business Days after the date on which such notice is delivered to the Administrative Agent and (ii) the identity of each Eligible Assignee to whom Borrower proposes any portion of such
increased or new Commitments be allocated and the amounts of such allocations; provided that any existing Lender approached to provide all or a portion of the increased or new Commitments may elect or decline, in its sole discretion, to
provide such increased or new Commitment. 

  

	 	b)	Conditions. The increased or new Commitments shall become effective, as of such Increase Effective Date; provided that; 

  

	 	i.	each of the conditions set forth in Section 6.02 shall be satisfied; 

  

	 	ii.	no Default would result from the borrowings to be made on the Increase Effective Date; 

  


 -3- 









	 	iii.	after giving pro forma effect to the borrowings to be made on the Increase Effective Date and to any change in Consolidated EBITDA and any increase in Indebtedness resulting from
the consummation of any acquisition permitted by Section 9.03(i) concurrently with such borrowings as of the date of the most recent financial statements delivered pursuant to Section 8.01(a) or (b), Borrower shall be in
compliance with each of the covenants set forth in Sections 9.13 and 9.14; 

  

	 	iv.	Borrower shall make any payments required pursuant to Section 5.05 in connection with any adjustment of Revolver Loans pursuant to Section 2.12(d); and


  

	 	v.	Borrower shall deliver or cause to be delivered any legal opinions or other documents reasonably requested by the Administrative Agent in connection with any such transaction.


  

	 	c)	Terms of New Loans and Commitments. The terms and provisions of Loans made pursuant to the new Commitments shall be as follows: 

  

	 	i.	terms and provisions of Revolver Loans made pursuant to Incremental Loan Commitments (“Incremental Loans”) shall be, except as otherwise set forth herein or
in the Increase Joinder, identical to the Revolver Loans (it being understood that Incremental Loans may be a part of the Loans); 

  

	 	ii.	the weighted average life to maturity of any Incremental Loans shall be no shorter than the weighted average life to maturity of the existing Revolver Loans;


  

	 	iii.	the maturity date of Incremental Loans (the “Incremental Loan Maturity Date”) shall not be earlier than the Termination Date; 

  

	 	iv.	the Applicable Margins for the Incremental Loans shall be determined by Borrower and the Lenders of the Incremental Loans; provided that in the event that the Applicable
Margins for any Incremental Loans are greater than the Applicable Margins for the Revolver Loans, then the Applicable Margins for the Revolver Loans shall be increased to the extent necessary so that the Applicable Margins for the Incremental Loans
are equal to the Applicable Margins for the Revolver Loans; provided, further, that in determining the Applicable Margins applicable to the Revolver Loans and the Incremental Loans, (x) original issue discount
(“OID”) shall be included (with OID being equated to interest based on an assumed four-year life to maturity), (y) upfront fees in excess of 1.0% (which shall be deemed to constitute like amounts of OID) payable by Borrower to
the Lenders of the Loans or the Incremental Loans in the primary syndication thereof shall be included and (z) customary arrangement or commitment fees payable to the Lead Arranger (or its affiliates) in connection with the Revolver Loans or to
one or more arrangers (or their affiliates) of the Incremental Loans shall be excluded; and 

  

	 	v.	to the extent that the terms and provisions of Incremental Loans are not identical to the Revolver Loans (except to the extent permitted by clause (iv) or (v) above) they
shall be reasonably satisfactory to the Administrative Agent. 

  

 -4- 








 The increased or new Commitments shall be effected by a joinder agreement (the “Increase
Joinder”) executed by Borrower, the Administrative Agent and each Lender making such increased or new Commitment, in form and substance satisfactory to each of them. The Increase Joinder may, without the consent of any other Lenders,
effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of this Section 2.12. In addition, unless otherwise
specifically provided herein, all references in Loan Documents to Revolver Loans shall be deemed, unless the context otherwise requires, to include references to Revolver Loans made pursuant to new Commitments and Incremental Loans that are Revolver
Loans, respectively, made pursuant to this Agreement. 
  

	 	d)	Adjustment of Revolver Loans. Each Revolver Lender that is acquiring a new or additional Revolver Commitment on the Increase Effective Date shall make a Revolving Loan, the
proceeds of which will be used to prepay the Revolver Loans of the other Revolver Lenders immediately prior to such Increase Effective Date, so that, after giving effect thereto, the Revolver Loans outstanding are held by the Revolver Lenders pro
rata based on their Revolver Commitments after giving effect to such Increase Effective Date. If there is a new borrowing of Revolver Loans on such Increase Effective Date, the Revolver Lenders after giving effect to such Increase Effective Date
shall make such Revolver Loans in accordance with Section 2.01. 

  

	 	e)	Equal and Ratable Benefit. The Loans and Commitments established pursuant to this paragraph shall constitute Loans and Commitments under, and shall be entitled to all the
benefits afforded by, this Agreement and the other Loan Documents, and shall, without limiting the foregoing, benefit equally and ratably from the Guarantees and security interests created by the Security Instruments. The Borrower shall take any
actions reasonably required by the Administrative Agent to ensure and/or demonstrate that the Lien and security interests granted by the Security Instruments continue to be perfected under the UCC or otherwise after giving effect to the
establishment of any such new Commitments.” 

 (d) Section 12.06(c) of the Credit Agreement is hereby
amended and restated as follows: 
 “Register. The Administrative Agent, acting solely for this purpose as an agent
of the Borrower, shall maintain at one of its offices in Charlotte, North Carolina, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and
principal and interest amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The Administrative Agent shall identify in the Register those Term Lenders that have agreed
to make the Decline Commitment (and their assignees). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon
reasonable prior notice.” 
 Section 2. Agreement to Decline Prepayment of Term Loan 
 (a) Subject to the satisfaction of the conditions set forth in Section 3 hereof, to the extent the Borrower consummates a senior or subordinated
unsecured note offering within 45 business days of the Amendment No. 1 and Agreement Effective Date (as defined below) (a “Specified Note Offering”), each Term Lender that executes clause (2)(A) of the signature page below
hereby agrees, as to 

  

 -5- 








 
all Term Loans held by such Term Lender, which agreement shall also be binding upon assignees of such Term Loans, to decline the prepayment of its Term Loans
pursuant to Section 3.01(b)(vii) of the Credit Agreement up to an amount that, together with the aggregate amount of all other Term Loan prepayments from the proceeds of a Specified Note Offering declined by Term Lenders pursuant to
Section 3.01(b)(vii) of the Credit Agreement, equals the outstanding amount of Revolving Loans at such time, such calculation to be made by the Administrative Agent (the “Agreement to Decline”). 
 Section 3. Conditions Precedent to the Effectiveness of this Amendment No. 1 and Agreement 
 (a) This Amendment shall become effective as of the date hereof (the “Amendment No. 1 and Agreement Effective Date”) when, and only
when, each of the following conditions precedent shall have been (or is or will be substantially concurrently therewith) satisfied or waived by the Administrative Agent:

Borrower, (2) the Administrative Agent and (3) the Required Lenders with respect to amendments described in Section 1 and each of the Term Lenders agreeing to the Agreement to Decline described in Section 2; provided, that
if the consent of the Required Lenders is received but the consent of all of the Term Lenders to the Agreement to Decline is not received, the amendments described in Section 1 shall become effective but the Agreement to Decline shall become
operative only with respect to the Term Lenders who have consented to the Agreement to Decline and shall have no effect on the Term Lenders who have not consented to the Agreement to Decline; 
 (ii) The Administrative Agent shall have received an opinion of legal counsel for the Borrower, dated the Amendment No. 1 and
Agreement Effective Date and addressed to the Administrative Agent and the Lenders, which opinion shall provide, among other things, that the execution and delivery of the Amendment by the Borrower and the consummation of the transactions
contemplated thereby will not violate the corporate instruments of the Borrower or the terms of the Loan Documents, and shall otherwise be in form and substance acceptable to the Administrative Agent and the Lenders; 
 (iii) The Borrower shall have paid (1) the Administrative Agent the fees in the amounts previously agreed to be received on the
Amendment No. 1 and Agreement Effective Date and (2) all reasonable out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation, reproduction, execution and delivery of this Amendment No. 1 and
Agreement (including, without limitation, the reasonable fees and out-of-pocket expenses of counsel for the Administrative Agent with respect thereto); 
 (iv) The Borrower shall have paid a fee to (i) each Lender who consents to this Amendment No.1 and Agreement on or prior to 12:00pm, Charlotte, NC time, on June 12, 2008 in an amount equal to 25 basis points
of such consenting Lender’s Term Loans and used and unused Revolver Commitments on the Amendment No.1 and Agreement Effective Date; 
 (v) On the date each Term Lender who executes the Agreement to Decline pursuant to Section 2 hereof declines the entire portion of the prepayment of its Term Loans pursuant to Section 3.01(b)(vii) of the
Credit Agreement, the Borrower shall pay a fee to each such Term Lender in an amount equal to such Term Lender’s pro rata share of total outstanding Term Loans multiplied by the product of 50 basis points and the aggregate net proceeds from a
Specified Note Offering that are applied to repay outstanding Revolving Loans.
