In furtherance and not in limitation of the respective foregoing, neither Agent or any of its Affiliates, nor Issuing Bank or any of its correspondents, participants or assignees of the Issuing Bank shall be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if Agent or Issuing Bank shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of Borrower against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among Borrower and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Agent or Issuing Bank, including any governmental acts, and none of the above shall affect or impair, or prevent the vesting of, any of Agent’s or Issuing Bank’s rights or powers hereunder. Nothing in the preceding sentence shall relieve Agent or Issuing Bank from liability for Agent’s or Issuing Bank’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with actions or omissions described in such clauses (i) through (viii) of such sentence but only to the extent of any direct, as opposed to consequential or exemplary, damages suffered by Borrower due to such actions or omissions or due to Issuing Bank’s willful failure to pay under any Letter of Credit after presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In no event shall Agent or Agent’s Affiliates or Issuing Bank or any of its correspondents, participants or assignees be liable to the Borrower for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit.





Without limiting the generality of the foregoing, Agent and each of its Affiliates and Issuing Bank and its correspondents, participants or assignees (i) may rely on any oral or other communication believed in good faith by it to have been authorized or given by or on behalf of the applicant for a Letter of Credit, (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by it; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on it in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document (each an “Order”) and honor any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit.





In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by Agent, its Affiliates, Issuing Bank or its correspondents, participants or assignees under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment), shall not put it under any resulting liability to Borrower or any Lender.”

(iii)           any lack of validity or enforceability of any Letter of Credit;





(iv)           any claim of breach of warranty that might be made by Borrower or any Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, crossclaim, defense or other right which Borrower or any Lender may have at any time against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), Agent or any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between Borrower or any Subsidiaries of Borrower and the beneficiary for which any Letter of Credit was procured);

(viii)         any failure by the Agent or any of Agent’s Affiliates or Issuing Bank or any of its correspondents, participants or assignees to issue any Letter of Credit in the form requested by Borrower, unless such Person has received written notice from Borrower of such failure within three (3) Business Days after the Agent or Issuing Bank shall have furnished Borrower a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice;





(ix)           any Material Adverse Effect on Borrower or any Guarantor;
