Section 12.04      Increased Costs .

If the adoption of, or any change in, any Requirements of Law or in the interpretation or application thereof by any Governmental Authority, or compliance by Buyer with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority having jurisdiction over Buyer made after the date of this Agreement, shall: (a) subject Buyer to any Taxes (other than (i) Indemnified Taxes, (ii) Taxes described in clauses (b) through (d) of the definition of “Excluded Taxes” or (iii) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto, (b) impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account

Section 12.06      Taxes .

(a)      Any and all payments by or on account of any obligation of Seller under any Repurchase Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law requires the deduction or withholding of any Tax from any such payment, then Seller shall make (or cause to be made) such deduction or withholding and shall timely pay (or cause to be timely paid) the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable shall be increased by Seller as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 12.06 ) Buyer receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b)      Seller shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)      Seller shall indemnify Buyer, within ten (10) Business Days after written demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 12.06 ) payable or paid by Buyer or required to be withheld or deducted from a payment to Buyer, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Seller by Buyer shall be conclusive absent manifest error.

(d)      As soon as practicable after any payment of Taxes by Seller to a Governmental Authority pursuant to this Section 12.06 , Seller shall deliver to Buyer the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to Buyer.

(e)      (i) If Buyer is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Repurchase Document, Buyer shall deliver to Seller, at the time or times reasonably requested by Seller, such properly completed and executed documentation reasonably requested by Seller as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, Buyer, if

reasonably requested by Seller, shall deliver such other documentation prescribed by applicable law or reasonably requested by Seller as will enable Seller to determine whether or not Buyer 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 such documentation set forth in Section 12.06(e)(ii)(A) , Section 12.06(e)(ii)(B) and Section 12.06(e)(ii)(D) below) shall not be required if in Buyer’s reasonable judgment such completion, execution or submission would subject Buyer to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of Buyer.

(ii)      Without limiting the generality of the foregoing:

(A)      if Buyer is a U.S. Person, it shall deliver to Seller on or prior to the date on which Buyer becomes a Party under this Agreement (and from time to time thereafter upon the reasonable request of Seller), executed copies of IRS Form W‑9 certifying that Buyer is exempt from U.S. federal backup withholding tax;

(B)      if Buyer is a Foreign Buyer, it shall, to the extent it is legally entitled to do so, deliver to Seller (in such number of copies as shall be requested by Seller) on or prior to the date on which Buyer becomes a Party under this Agreement (and from time to time thereafter upon the reasonable request of Seller), whichever of the following is applicable:

(I)      in the case of a Foreign Buyer claiming the benefits of an income tax treaty to which the United States is a Party, (x) with respect to payments of interest under any Repurchase Document, executed copies of IRS Form W‑8BEN or IRS Form W‑8BEN‑E (as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Repurchase Document, IRS Form W‑8BEN or IRS Form W‑8BEN‑E (as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(II)      executed copies of IRS Form W‑8ECI;

(III)      in the case of a Foreign Buyer 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 Buyer is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of Seller within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “ U.S. Tax Compliance

Certificate ”) and (y) executed copies of IRS Form W‑8BEN or IRS Form W‑8BEN‑E (as applicable); or

(IV)      to the extent a Foreign Buyer is not the beneficial owner, executed copies of IRS Form W‑8IMY, accompanied by IRS Form W‑8ECI, IRS Form W‑8BEN, IRS Form W‑8BEN‑E, a U.S. Tax Compliance Certificate, IRS Form W‑9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Buyer is a partnership and one or more direct or indirect partners of such Foreign Buyer are claiming the portfolio interest exemption, such Foreign Buyer may provide a U.S. Tax Compliance Certificate on behalf of each such direct and indirect partner;

(C)      if Buyer is a Foreign Buyer, it shall, to the extent it is legally entitled to do so, deliver to Seller (in such number of copies as shall be requested by Seller) on or prior to the date on which Buyer becomes a Party under this Agreement (and from time to time thereafter upon the reasonable request of Seller), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit Seller to determine the withholding or deduction required to be made; and

(D)      if a payment made to Buyer under any Repurchase Document would be subject to U.S. federal withholding Tax imposed by FATCA if Buyer were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), Buyer shall deliver to Seller at the time or times prescribed by law and at such time or times reasonably requested by Seller 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 Seller as may be necessary for Seller to comply with its obligations under FATCA and to determine that Buyer has complied with Buyer’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Buyer agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Seller in writing of its legal inability to do so.

(f) If any Party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 12.06 (including by the payment of additional amounts pursuant to this Section 12.06 ), it shall pay to the

indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 12.06 with respect to the Taxes giving rise to such refund), net of all out‑of‑pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund).  Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 12.06(f) ( plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority.  Notwithstanding anything to the contrary in this Section 12.06(f) , in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 12.06(f) the payment of which would place the indemnified party in a less favorable net after‑Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts giving rise to such refund had never been paid.  This Section 12.06(f) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(g) For the avoidance of doubt, for purposes of this Section 12.06 , the term “applicable law” includes FATCA.

(e) Section 13.01(a) of the Repurchase Agreement is hereby amended to (i) delete the words “on a net after‑tax basis from and” from the 4th line thereof, (ii) delete the words “taxes (other than income taxes and franchise taxes of Buyer or any Eligible Assignee)”, from the 6th line thereof, and (iii) add the following new sentence to the end of Section 13.01(a) :

“This Section 13.01(a) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non‑Tax claim.”

(f) Section 17.08(b) of the Repurchase Agreement is hereby amended to replace the final two sentences thereof in their entirety with the following:

“Each Participant shall be entitled to the benefits of Article 12 (subject to the requirements and limitations therein, including the requirements under Section 12.06(e) (it being understood that the documentation required under Section 12.06(e) shall be delivered to the participating Buyer)) and Article 13 to the same extent as if it had acquired its interest by assignment pursuant to Section 17.08(c) , provided that such Participant shall not be entitled to receive any greater payment under Section 12.04 or Section 12.06 than its participating Buyer would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from the adoption of or any change in any Requirements of Law or in the interpretation or application thereof by a Governmental Authority or compliance by Buyer or such Participant with a request or directive (whether or not having the force of law) from a central bank or other Governmental Authority having jurisdiction over Buyer or such Participant, in each case made or issued after the Participant acquired the applicable participation. To the extent permitted by Requirements of Law, each

Participant shall also be entitled to the benefits of Sections 10.02(i) and 17.17 to the same extent as if it had acquired its interest by assignment pursuant to Section 17.08(c) .”

(g) Sections 17.08(f) and (g) of the Repurchase Agreement are hereby amended and restated in their entirety to read as follows:

“(f)      Buyer, acting solely for this purpose as a non‑fiduciary agent of Seller, shall maintain a copy of each Assignment and Acceptance and a register for the recordation of the names and addresses of the Eligible Assignees that become Parties hereto and, with respect to each such Eligible Assignee, the aggregate assigned Purchase Price and applicable Price Differential (the “ Register ”). The entries in the Register shall be conclusive absent manifest error, and the Parties shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Buyer for all purposes of this Agreement. The Register shall be available for inspection by the Parties at any reasonable time and from time to time upon reasonable prior notice.

(g)      Each Party that sells a participation shall, acting solely for this purpose as a non‑fiduciary agent of Seller, maintain a register on which it enters the name and address of each Participant and, with respect to each such Participant, the aggregate participated Purchase Price and applicable Price Differential, and any other interest in any obligations under the Repurchase Documents (the “ Participant Register ”); provided that no Party shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any obligations under any Repurchase Document) to any Person except to the extent that such disclosure is necessary to establish that such obligation is in registered form under Section 5f.103‑1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and the participating Party shall treat each Person whose name is recorded in the Participant Register as the owner of the applicable participation for all purposes of this Agreement notwithstanding any notice to the contrary.”
