 2. No Other Amendments. Except for the amendments set forth above, the
text of the Loan Agreement and all other Loan Documents shall remain unchanged and in full force and effect. No amendment, waiver or consent by the Administrative Agent, the Issuing Bank or the Lenders under the Loan Agreement or any other Loan
Document is granted or intended except as expressly set forth herein, and the Administrative Agent, the Issuing Bank and the Lenders expressly reserve the right to require strict compliance in all other respects (whether or not in connection with
any Requests for Advance). Except as set forth herein, the amendments agreed to herein shall not constitute a modification of the Loan Agreement or any of the other Loan Documents, or a course of dealing with the Administrative Agent, the Issuing
Bank and the Lenders at variance with the Loan Agreement or any of the other Loan Documents, such as to require further notice by the Administrative Agent, the Issuing Bank, the Lenders or the Majority Lenders to require strict compliance with the

applicable, or to the extent relating specifically to the earlier date. No Default or Event of Default now exists or will be caused hereby. 
  
 4. Counterparts. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument. 
  
 5. Governing Law. This Amendment shall be construed in accordance with and governed by the laws of the State of New York. 
  

 -5- 

 6. Severability. Any provision of this Amendment which is prohibited or unenforceable shall be

 “(s) the failure of the Parent or Verestar, Inc. to
comply with its respective obligations in the second sentence of Section 2(c)(ii) or the fifth or sixth sentence of Section 3(a) of the Seventh Amendment to the Prior Loan Agreement dated as of October 18, 2002; provided that the failure of
Verestar, Inc. to comply with its obligations in (i) the second sentence of Section 2(c)(ii) of such Seventh Amendment shall be subject to any cure period applicable to Section 5.6 hereof in Section 8.1(d) hereof, and (ii) Sections 7.3, 7.6,
7.12 and 7.14 as required in such Seventh Amendment shall be subject to any cure period applicable for such section as set forth in Section 8.1(d) hereof.” 
  
 G. Section 11.20, Verestar Entities, shall be amended to be as follows: 
  
 “Section 11.20 Verestar Entities. The Borrowers
hereby acknowledge and agree that any net cash proceeds received by the Parent or any Borrower from any Verestar Entity (whether in connection with the bankruptcy proceeding of 

  

 3 

 
Verestar or otherwise) in respect of its investment therein or any loans thereto shall be paid to the Administrative Agent and shall be applied to the Loans
then outstanding on a pro rata basis. Accrued interest on the principal amount of the Loans being repaid pursuant to this Section 11.20 to the date of such repayment will be paid by the Borrowers concurrently with such principal repayment. All
repayments under this Section 11.20 of each of the Term Loan A Loans and Term Loan B Loans shall be applied to the repayments for such Loan in Section 2.7(b)(i) hereof and with respect to any Incremental Facility which is a term loan, to the
repayments for such Incremental Facility Loans as set forth in the applicable Notice of Incremental Facility Commitment, in each case in inverse order of maturity. The Revolving Loan Commitments and any Incremental Facility Commitments with respect
to any Incremental Facility which is a revolving credit facility shall be automatically and permanently reduced by an amount equal to the repayment of the Revolving Loans or Incremental Facility Loans which are revolving loans, as applicable, made
pursuant to this Section 11.20; provided, however, that if there are no Loans outstanding, or if the repayment amount exceeds the Loans then outstanding the Revolving Loan Commitments and any Incremental Facility Commitments, as
applicable, shall be reduced on a pro rata basis by an aggregate amount equal to such repayment amount, or the excess of such repayment amount over the Loans (which reduction shall be in addition to any reduction set forth in the first part of this
sentence), as applicable, regardless of any repayment of the Revolving Loans. Reductions under this Section 11.20 to the Revolving Loan Commitments shall be applied to the reductions set forth in Section 2.5(a) hereof in inverse order of reductions
set forth therein and reductions with respect to any Incremental Facility Commitments under this Section 11.20, if applicable, shall be applied to the reductions set forth in the applicable Notice of Incremental Facility in inverse order of
reductions set forth therein.” 
  
 In furtherance of the foregoing provisions
of this Section 4, each Term Loan C Lender hereby agrees that for all purposes under the Loan Agreement, such Term Loan C Lender shall be deemed to have consented to any amendment, consent, waiver or deletion of any of the foregoing provisions of
the Loan Agreement (as such provisions are in effect with respect to all Lenders (other than the Term Loan C Lenders)), upon the consent of the Majority Lenders (which shall be determined after the Closing Date and after giving effect to the consent
hereby of the Term Loan C Lenders) and so long as such amendment, waiver, consent or deletion does not result in a change to such provisions which is less restrictive to the Borrowers and the Restricted Subsidiaries than the provisions set forth in
this Section 4. 
  
 5. Each Term Loan C Lender hereby agrees that
on and after the date hereof, such Term Loan C Lender is bound by the terms and conditions set forth in this Notice of Incremental Facility Commitment and the Loan Agreement as a Term Loan C Lender. 
  
 6. It is understood and agreed that any Term Loan C Lender that also holds
any Term Loan B Loans (“Existing Loans”) under the Loan Agreement shall be deemed to have agreed, unless it notifies the Administrative Agent otherwise, that the Term Loan C Loans to be made by such Term Loan C Lender shall, to the
extent of the portion thereof not exceeding the 

  

 4 

 
aggregate principal amount of the Existing Loans of such Term Loan C Lender, be made through such Existing Loans being converted into Term Loan C Loans (and
each reference in this Notice of Incremental Facility Commitment or the Loan Agreement to the “making” of any Incremental Facility Loan, or words of similar import, shall in the case of such Term Loan C Lender be deemed to include such
conversion). 
  
 7. The parties hereto agree that this Notice
shall be construed in accordance with and governed by the internal laws of the State of New York applicable to agreements made and to be performed the State of New York. 
  
 Capitalized terms used in this Notice of Incremental Facility Commitment and not otherwise defined herein are used as
defined in the Loan Agreement. 
  

 5 

 IN WITNESS WHEREOF, each of the Borrowers, acting through an Authorized Signatory, has signed this Notice
of Incremental Facility Commitment on the 28th day of January, 2004.
