the business, assets, operations or financial condition of the Borrower and the Subsidiaries, taken as a whole, since December 31, 2005, which could reasonably be expected to have a material adverse effect on the creditworthiness of the

issuances, amendments, renewals or extensions of a Letter of Credit after the First Amendment Effective Date, the representation set forth in Section 3.06)”

 5. Assignment of Loans, LC Disbursements and LC Participations to Reflect Amended Commitments. On
the Effective Date, the Banks whose Pro Rata Shares after giving effect to this Amendment are greater than their Pro Rata Shares prior to giving effect to this 

  

 9 








 
Amendment (each an “Increasing Bank”) shall purchase, as an assignment from the Banks whose Pro Rata Shares after giving effect to this
Amendment are less than their Pro Rata Shares prior to giving effect to this Amendment (each a “Decreasing Bank”), such portions of the Decreasing Banks’ Loans, unreimbursed LC Disbursements and participations in Letters of
Credit outstanding at such time such that, after giving effect to such assignments, the respective aggregate amount of Loans, unreimbursed LC Disbursements and participations in Letters of Credit of each Bank shall be equal to such Bank’s Pro
Rata Share of the aggregate Loans, unreimbursed LC Disbursements and participations in Letters of Credit outstanding. The purchase price for the Loans, unreimbursed LC Disbursements and participations in Letters of Credit so assigned shall be the
sum of (i) the principal amount of the Loans and unreimbursed LC Disbursements so assigned plus the amount of accrued and unpaid interest thereon as of the date of assignment and (ii) the amount of accrued and unpaid LC Participation Fees
as of the date of assignment on the participations in Letters of Credit so assigned. Each Increasing Bank shall pay the aggregate purchase price payable by it to the Administrative Agent on the Effective Date and the Administrative Agent shall
promptly forward to each Decreasing Bank the portion thereof payable to it. Upon payment by an Increasing Bank of the purchase price payable by it to a Decreasing Bank, such Decreasing Bank shall be automatically deemed to have sold and made the
applicable assignments to such Increasing Bank and shall, to the extent of the interest assigned, be released from its obligations under the Loan Documents, and such Increasing Bank shall be automatically deemed to have purchased and assumed such
assignments from such Decreasing Bank and, if not already a Bank hereunder, shall be a party hereto and, to the extent of the interest assigned, have the rights and obligations of a Bank under the Loan Documents. Without in any way limiting the
foregoing, each Decreasing Bank whose Pro Rata Share after giving effect to this Amendment is zero, shall, by executing its signature page hereto, be deemed on the Effective Date to consent to this Amendment and, simultaneously with the
effectiveness hereof, without any further action on its part, to assign all of its Commitments, Loans and LC Disbursements, with the effect that it shall be discharged from its Commitments and other obligations (other than the return of its Notes)
and shall no longer be a Bank under the Credit Agreement. The Borrower and the Administrative Agent shall be deemed to have consented to the assignments effected pursuant to this Section 5. The Administrative Agent shall record the Commitments,
Loans and LC Disbursements of each Bank as provided in Section 10.04(c) of the Credit Agreement to reflect such assignments. 
 6.
Effect of Interest and Fee Rate Amendments. Any changes in interest or fees rates effected by this Amendment shall apply with respect to interest and fees accruing for the Effective Date and periods thereafter, while interest and fees rates
in effect prior to the effectiveness of such amendments shall continue to be applicable for accruals for periods prior to the Effective Date. 
 7. Confirmation of Amended Agreement. The Credit Agreement as amended by this Amendment is and shall continue to be in full force and effect and is hereby in all respects confirmed, approved and ratified. 
 8. Governing Law. This Amendment shall be construed in accordance with and governed by the law of the State of New York. 
  

 10 








 9. Counterparts. This Amendment may be signed in any number of counterparts, each of which shall
be an original, with the same effect as if the signatures thereto were upon the same instrument. 
 10. Headings. Section headings in
this Amendment are included herein for convenience and reference only and shall not constitute a part of this Amendment for any other purpose.
