In addition, any Lender or L/C Issuer, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender or L/C Issuer is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than the documentation described in (i), (ii), (iii), (iv), (v) and (vii) below) shall not be required if in the Lender's or the L/C Issuer’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender or L/C Issuer. Without limiting the generality of the foregoing, in the event that the Borrower is a resident for tax purposes in the United States, any Lender or L/C Issuer shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Lender or L/C Issuer becomes a Lender or L/C Issuer under this Credit Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but, in the case of any Foreign Lender, only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(iv)    in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that

such Foreign Lender is not (A) a "bank" within the meaning of section 881(c)(3)(A) of the

Code, (B) a "10 percent shareholder" of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a "controlled foreign corporation" described in section 881(c)(3)(C) of the Code and (y) duly completed and executed originals of IRS Form W-8BEN or W-8BEN-E (as applicable);

(v)     to the extent a Foreign Lender is not the beneficial owner, properly completed and executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or W-8BEN-E (as applicable), IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable;

(vi)    any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower to determine the withholding or deduction required to be made.

    

(vii)    If a payment made to a Lender or an L/C Issuer under any Credit Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender or L/C Issuer fails to comply with any requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender or L/C Issuer shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by applicable Law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender or such L/C Issuer has complied with such Lender’s or such L/C Issuer’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (vii), “FATCA” shall include any amendments made to FATCA after the date of this Credit Agreement.

To the extent that the relevant documentation provided pursuant to this section is rendered obsolete or inaccurate in any material respect as a result of changes in circumstances with respect to the status of a Lender or an L/C Issuer, such Lender or such L/C Issuer shall, to the extent permitted by applicable Law, deliver to the Borrower and the Administrative Agent revised and/or updated documentation or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

For purposes of determining withholding Taxes imposed under FATCA, from and after the Third Amendment Effective Date, the Borrower and the Administrative Agent shall treat (and the Lenders and the L/C Issuers hereby authorize the Administrative Agent to treat) each of the Loans as not qualifying as “grandfathered obligations” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).

In addition, any Lender or L/C Issuer, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender or L/C Issuer is subject to backup withholding or information reporting requirements.

(iv)    in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a "bank" within the meaning of section 881(c)(3)(A) of the Code, (B) a "10 percent shareholder" of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a "controlled foreign corporation" described in section 881(c)(3)(C) of the Code and (y) duly completed and executed originals of IRS Form W-8BEN or W-8BEN-E (as applicable);

(v)     to the extent a Foreign Lender is not the beneficial owner, properly completed and executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or W-8BEN-E (as applicable), IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable;

(vi)    any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower to determine the withholding or deduction required to be made.

    

(vii)    If a payment made to a Lender or an L/C Issuer under any Credit Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender or L/C Issuer fails to comply with any requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender or L/C Issuer shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by applicable Law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender or such L/C Issuer has complied with such Lender’s or such L/C Issuer’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (vii), “FATCA” shall include any amendments made to FATCA after the date of this Credit Agreement.

To the extent that the relevant documentation provided pursuant to this section is rendered obsolete or inaccurate in any material respect as a result of changes in circumstances with respect to the status of a Lender or an L/C Issuer, such Lender or such L/C Issuer shall, to the extent permitted by applicable Law, deliver to the Borrower and the Administrative Agent revised and/or updated documentation or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

For purposes of determining withholding Taxes imposed under FATCA, from and after the date of the Second Amendment, the Borrower and the Administrative Agent shall treat (and the Lenders and the L/C Issuers hereby authorize the Administrative Agent to treat) each of the Loans as not qualifying as “grandfathered obligations” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).
