(a) As of the applicable Replacement Date, unless otherwise agreed upon by Seller and Purchaser, either:

(i) a Replacement Mortgage Loan shall satisfy the following criteria:

4

(ii) if Seller is unable to satisfy the conditions in Section 2.02(a)(i) after using commercially reasonable efforts, Seller shall use its best efforts to substitute the Refinanced Mortgage Loan with a Replacement Mortgage Loan satisfying the following criteria:

(b) If a Replacement Mortgage Loan would otherwise meet the criteria set forth in Section 2.02(a) but has not been sold to an Agency as of the Replacement Loan Identification Date, in lieu of substituting a loan pursuant to Section 2.02(a)(ii) above, the Seller may include such Replacement Mortgage Loan in the Available Portfolio; provided (i) the servicing fee rate for such Replacement Mortgage Loan shall be deemed to be 0.30% per annum and (ii) if at any time such Replacement Mortgage Loan fails to meet the criteria set forth in

5

Section 2.02(a), the Seller shall be required to substitute a loan for such Replacement Mortgage Loan pursuant to Section 2.02(a)(ii) above.

(c) Seller shall not be in breach of Section 2.01 on any Replacement Date if, after using best efforts to select Replacement Mortgage Loans to substitute Refinanced Mortgage Loans pursuant to Section 2.02(a)(ii), the aggregate outstanding principal balance of the residential mortgage loans in the Available Portfolio as of such Replacement Date is equal to or greater than 90% of the aggregate outstanding principal balance of the Refinanced Mortgage Loans that were refinanced during the Related Collection Period as measured on the opening of business on their respective Refinancing Date.

Section 2.03 Refinancing Incentives.

For any Replacement Date beginning with the Replacement Date in June 2012, Seller shall not be required to substitute Replacement Mortgage Loans for Refinanced Mortgage Loans in an aggregate principal amount up to the Maximum Retained Refinancing Loan Amount. For purposes of this Section 2.03, the following definitions shall apply:

Replacement Shortfall: With respect to any Replacement Date and the Related Collection Period, the aggregate outstanding principal balance of the New Mortgage Loans that were originated by Seller or an affiliate thereof during the Related Collection Period as measured on the opening of business on their respective Refinancing Date, minus the aggregate outstanding principal balance of the residential mortgage loans in the Available Portfolio as of such Replacement Date.

Excess Refinancing Percentage: With respect to any Replacement Date, a percentage equal to the excess, if any, of (a) a fraction, expressed as a percentage, the numerator of which is equal to the aggregate principal balance of New Mortgage Loans that were originated by Seller or an affiliate thereof over the Related Collection Period and the two Collection Periods prior to such Related Collection Period (the “Quarterly Collection Period”) as measured on the opening of business on their respective Refinancing Date, minus the aggregate Replacement Shortfall over such Quarterly Collection Period, and the denominator of which is the aggregate principal balance of all voluntary prepayments received on the Mortgage Loans over the Quarterly Collection Period, over (b) 35%.

Refinancing Split Percentage: With respect to any Replacement Date, the Refinancing Split Percentage shown in the column of the table below corresponding to the Excess Refinancing Percentage therein:

6

Maximum Retained Refinancing Loan Amount: With respect to any Replacement Date, an amount, not less than zero, equal to the sum of (a) the product of (i) the Refinancing Split Percentage, if any, applicable to such Replacement Date, (ii) the Excess Refinancing Percentage applicable to such Replacement Date and (iii) the aggregate principal balance of New Mortgage Loans that were refinanced with Seller or an affiliate thereof during the Related Collection Period, plus (b) the Carryover Retained Amount, minus (c) the applicable Replacement Shortfall.

Carryover Retained Amount: With respect to any Replacement Date beginning with the Replacement Date in July 2012, the excess, if any, of the Maximum Retained Refinancing Loan Amount for the prior Replacement Date over the aggregate outstanding principal balance of the Mortgage Loans that were retained by Seller pursuant to this Section 2.03 on the prior Replacement Date.

Section 2.04 Procedures for Replacement Mortgage Loans.

(a) Not later than the Replacement Loan Identification Date, Seller shall (i) notify Purchaser of the identity of each Mortgage Loan that became a Refinanced Mortgage Loan during the Related Collection Period, (ii) calculate the Excess Refinancing Percentage, the Refinancing Split Percentage, the Maximum Retained Refinancing Loan Amount and the Carryover Retained Amount for the following Replacement Date, and notify Purchaser of such amounts in writing, (iii) provide Purchaser with a list of potential Replacement Mortgage Loans (the “Available Portfolio”), selected on the basis that the Excess Refinancing Percentage is equal to zero, and (iv) provide Purchaser with a list of residential mortgage loans selected from the Available Portfolio to be designated as Mortgage Replacement Loans (the “Replacement Portfolio”) on the following Replacement Date and a list of residential mortgage loans selected from the Available Portfolio to be excluded from the pool of Replacement Mortgage Loans (the “Retained Portfolio”) on the following Replacement Date in accordance with Section 2.03.

(b) Purchaser may submit an objection to the proposed Available Portfolio, the proposed Replacement Portfolio or the proposed Retained Portfolio not later than five Business Days following receipt of the notice of the proposed portfolios pursuant to Section 2.04(a). If Purchaser submits an objection, Seller and Buyer shall work together in good faith over the next five Business Days (the “Selection Period”) to mutually agree on the Replacement Portfolio and the Retained Portfolio. During the Selection Period, Seller may suggest alternative Replacement Mortgage Loans that meet the criteria of Section 2.02(a)(ii). If Seller and Purchaser are unable to agree on a Replacement Portfolio and a Retained Portfolio (if applicable) by close of business on the Business Day prior to the Replacement Date, Seller and Purchaser may modify the percentages in the definitions of Replacement Mortgage Loan Excess Spread,

7

Retained Replacement Mortgage Loan Express Spread, Excess Servicing Spread, Retained Servicing Spread and in the Priority of Payments, as applicable, to reflect the relative values that Seller and Purchaser would have had in the Excess Servicing Spread and Retained Servicing Spread but for the inability of Seller and Purchaser to mutually agree on such portfolios.

(c) Unless mutually agreed upon by Seller and Purchaser, the Retained Portfolio and the Replacement Portfolio with respect to any Replacement Date shall satisfy the following criteria:

(i) The aggregate outstanding principal balance of the residential mortgage loans in the Retained Portfolio shall not exceed the Maximum Retained Refinancing Loan Amount;

(ii) The weighted average servicing fee rate for the residential mortgage loans in the Retained Portfolio shall be substantially equal to the weighted average servicing fee rate for the Replacement Mortgage Loans in the Replacement Portfolio;

(iii) The weighted average interest accrual rate per annum of the residential mortgage loans in the Retained Portfolio shall be within 12.5 basis points per annum of the weighted average interest rate of the Replacement Mortgage Loans in the Replacement Portfolio;

(iv) The weighted average final maturity date of the residential mortgage loans in the Retained Portfolio shall be within six months of the weighted average final maturity date of the Replacement Mortgage Loans in the Replacement Portfolio; and

(v) The remaining credit characteristics of the pool of residential mortgage loans in the Retained Portfolio (other than as specified in clauses (ii), (iii) and (iv) above) shall be substantially the same as the credit characteristics of the pool of Replacement Mortgage Loans in the Replacement Portfolio.

(d) Exhibit B provides an example of the calculations to be made pursuant to this Section 2.04.

Section 2.05 Assignment of Replacement Mortgage Loan Excess Servicing Spread.

(a) Subject to the satisfaction of the terms and conditions in this Agreement, on each Replacement Date, Seller shall execute and deliver an Assignment Agreement for the Replacement Mortgage Loan Excess Servicing Spread to be assigned on such Replacement Date with respect to Replacement Mortgage Loans; provided, however, that

(i) Purchaser shall be entitled to all Replacement Mortgage Loan Excess Spread and Seller shall be entitled to all Retained Replacement Mortgage Loan Excess spread arising with respect to each such Replacement Mortgage Loan on and after the Refinancing Date with respect to the related Refinanced Mortgage Loan,

8

(ii) Seller shall deposit all Servicing Spread Collections received with respect to such Replacement Mortgage Loans on and after the Refinancing Date with respect to the related Refinanced Mortgage Loans into the Third Party Controlled Collection Account (other than amounts on deposit in the Lockbox Account, which shall be deposited into the Third Party Controlled Collection Account in accordance with the Excess Servicing Spread Sale and Assignment Agreement) not later than the Replacement Date,

(iii) for each Replacement Mortgage Loan that was originated on or after the Refinancing Date of the related Refinanced Mortgage Loan, Seller shall deposit all Servicing Spread Collections with respect to amounts prepaid at the time of closing of such Replacement Mortgage Loan, if applicable, into the Third Party Controlled Custodial Account not later than the Replacement Date,

(iv) if the Purchaser’s rights under this Agreement have been assigned to a third party that is not a party or an assignee of the Excess Servicing Spread Sale and Assignment Agreement (a “Third Party Assignment”), such third party (a “Replacement Agreement Third Party”) shall have entered into a new agreement (a “Third Party Base Agreement”) with Seller or Seller’s assignee that provides such Replacement Agreement Third Party with the same rights with respect to any Replacement Mortgage Loan Excess Spread arising after the date of the Third Party Assignment (“Third Party Spread”) that Purchaser would have under the Excess Servicing Spread Sale and Assignment if the Third Party Assignment had not occurred; it being understood that Purchaser shall not have any rights in, and the Excess Spread Sale and Assignment Agreement shall not apply to, any Third Party Spread.

(b) Upon delivery of an Assignment Agreement,

(i) Each of the Replacement Mortgage Loans whose Replacement Loan Excess Servicing Spread is assigned thereunder shall be deemed to be a “Mortgage Loan” for all purposes of the Base Agreement, mutatis mutandis, subject to the terms and conditions thereof and hereof; and

(ii) Each reference in the Excess Servicing Spread Sale and Assignment Agreement to the “Sale Date” (or such comparable definition in any other Base Agreement) shall be deemed to refer to the Refinancing Date.

Section 2.06 Base Servicing Fees with respect to Replacement Mortgage Loans.

Notwithstanding any provision of the Base Agreement to the contrary, the Base Servicing Fee with respect to Replacement Mortgage Loan shall begin to accrue as of the Collection Period prior to the applicable Replacement Date. In no event shall Base Servicing Fees accrue concurrently on any day for a Refinanced Mortgage Loan and for a Replacement Mortgage Loan.

Section 2.07 Intent and Characterization.

(a) Seller and Purchaser intend that the assignments of the Replacement Mortgage Loan Excess Spread pursuant to this Agreement and each Assignment Agreement

9

constitute valid sales of such Replacement Mortgage Loan Excess Spread from Seller to Purchaser, conveying good title thereto free and clear of any Lien, and that the beneficial interest in and title to such Replacement Mortgage Loan Excess Spread not be part of Seller’s estate in the event of the bankruptcy of Seller. Seller and Purchaser intend and agree to treat the transfer and assignment of the Replacement Mortgage Loan Excess Spread as an absolute sale for tax purposes, and as an absolute and complete conveyance of title for property law purposes. Except for financial accounting purposes, neither party intends the transactions contemplated hereby to be characterized as a loan from Purchaser to Seller.

(b) In the event (but only in the event) that the conveyance of the Replacement Mortgage Loan Excess Spread is characterized by a court or governmental authority as security for a loan rather than a sale, Seller will be deemed to have granted to Purchaser, and Seller hereby grants to Purchaser, a security interest in all of its right, title and interest in, to and under the Replacement Mortgage Loan Excess Spread and all proceeds thereof as security for a loan in an amount equal to the product of (x) the aggregate outstanding Replacement Mortgage Loan principal balance as of the Replacement Date, (y) the Purchase Price Percentage and (z) 0.65.
