Any party obligated to provide Forward Collateral pursuant to an annex hereto (“Pledgor”) hereby grants to the other party (“Pledgee”) a continuing first security interest in and right of setoff against all Forward Collateral and all other securities, money and other property, and all proceeds of any of the foregoing, now or hereafter delivered by or on behalf of Pledgor to Pledgee, held or carried by Pledgee for the account of Pledgor or due from Pledgee to Pledgor (collectively, the “Collateral”), as security for the payment and performance by Pledgor of all obligations of Pledgor to Pledgee under this Agreement (the “Secured Obligations”). Pledgee shall be entitled to repledge or assign any and all Collateral to secure loans or other extensions of credit to Pledgee or other of its obligations, which obligations may be in amounts greater than, and may extend for periods of time longer than, the periods during which Pledgee is entitled to Collateral as security for the obligations of Pledgor; provided, however, that no such transaction shall relieve Pledgee of its obligations to transfer Collateral to Pledgor pursuant to Paragraph 7 of this Agreement or any annex hereto.

2 ¡ July 1996 ¡ Master Securities Forward Transaction Agreement

Each party represents and warrants to the other that (i) it is duly authorized to execute and deliver this Agreement, to enter into Transactions contemplated hereunder and to perform its obligations hereunder and has taken all necessary action to authorize such execution, delivery and performance; (ii) it will engage in such Transactions as principal (or, if agreed in writing, in the form of an annex hereto or otherwise, in advance of any Transaction by the other party hereto, as agent for a disclosed principal); (iii) the person signing this Agreement on its behalf is duly authorized to do so on its behalf (or on behalf of any such disclosed principal); (iv) it has obtained all authorizations of any governmental body required in connection with this Agreement and the Transactions hereunder and such authorizations are in full force and effect; and (v) the execution, delivery and performance of this Agreement and the Transactions hereunder will not violate any law, ordinance, charter, by-law or rule applicable to it or any agreement by which it is bound or by which any of its assets are affected. On the Trade Date for any Transaction each party shall be deemed to repeat all of the foregoing representations made by it.

In the event that (i) either party fails to make on the Settlement Date of any Transaction any payment of funds or any delivery of Securities required pursuant to such Transaction; (ii) an Act of Insolvency occurs with respect to either party; (iii) any representation made by either party shall have been incorrect or untrue in any material respect when made or repeated or deemed to have been made or repeated; or (iv) either party shall admit to the other its inability to, or its intention not to, perform its obligations hereunder (each an “Event of Default”):

4 ¡ July 1996 ¡ Master Securities Forward Transaction Agreement

The parties acknowledge that, and have entered hereinto and will enter into each Transaction hereunder in consideration of and in reliance upon the fact that, all Transactions hereunder constitute a single business and contractual relationship and have been made in consideration of each other. Accordingly, each of the parties agrees (i) to perform all of its obligations in respect of each Transaction hereunder, and that a default in the performance of any such obligations shall constitute a default by it in respect of all Transactions hereunder; (ii) that each of them shall be entitled to set off claims and apply property held by them in respect of any Transaction against obligations owing to them in respect of any other Transactions hereunder; and (iii) that payments, deliveries and other transfers made by either of them in respect of any Transaction shall be deemed to have been made in consideration of payments, deliveries and other transfers in respect of any such Transaction hereunder, and the obligations to make such payments, deliveries and other transfers may be applied against each other and netted.

The risk of loss of engaging in when-issued, TBA, dollar roll and other transactions that result or may result in the delayed delivery of securities can be substantial. Each party should carefully consider when such transactions are suitable for its financial condition, its investment objectives and any legal or regulatory restrictions placed upon it and whether the party has the operational resources in place to monitor the associated risks and contractual obligations over the term of the Transaction. A primary risk of such transactions is that the market value of the securities on the Settlement Date or at any time during the term of the Transaction could vary substantially from the price at which such securities are purchased or sold due to such factors as market-price fluctuations and interest-rate movements occurring between the Trade Date and the Settlement Date. A second risk is that on the Settlement Date one party to such a transaction may be unable to perform, resulting in substantial loss, including the possible loss of any Collateral held by the defaulting party. A third risk is that a party may from time to time take proprietary positions and/or make a market in securities identical or economically related to Transactions entered into with the other party. A party may also undertake proprietary activities, including hedging transactions related to the initiation or termination of a Transaction, that may adversely affect the market price, rate, index or other market factors underlying a Transaction and consequently the value of the Transaction. Finally, another risk relates to the requirements that may be imposed under an annex hereto that Forward Collateral be deposited at the Trade Date or periodically thereafter as the markets move against a party’s position. A party’s inability to meet a demand for such Forward Collateral, at times on short notice, may result in closing out of Transactions and losses to that party. This brief statement does not disclose all of the risks and other material considerations

July 1996 ¡ Master Securities Forward Transaction Agreement ¡ 5

of such transactions. Accordingly, before engaging in Transactions, each party should consult its own business, legal, tax and accounting advisers with respect to the proposed Transaction and examine the contractual arrangements contained herein carefully to determine all risks and whether the Transaction is appropriate for that party. Each party agrees that the other party is not acting as a fiduciary or an advisor for it in respect of this Agreement or any Transaction.

Any and all notices, statements, demands or other communications hereunder may be given by a party to the other by mail, facsimile, telegraph, messenger or otherwise to the address specified in Annex II hereto, or so sent to such party at any other place specified in a notice of change of address hereafter received by the other. All notices, demands and requests hereunder may be made orally, to be confirmed promptly in writing, or by other communication as specified in the preceding sentence.

This Agreement shall supersede any existing agreements between the parties containing general terms and conditions for when-issued, TBA, dollar roll and other transactions that result or may result in the delayed delivery of Securities. Each provision and agreement herein shall be treated as separate and independent from any other provision or agreement herein and shall be enforceable notwithstanding the unenforceability of any such other provision or agreement.

This Agreement shall be governed by the laws of the State of New York without giving effect to the conflicts of law principles thereof.

No express or implied waiver of any Event of Default by either party shall constitute a waiver of any other Event of Default and no exercise of any remedy hereunder by any party shall constitute a waiver of its right to exercise any other remedy hereunder. No modification or waiver of any provision of this Agreement and no consent by any party to a departure herefrom shall be effective unless and until such shall be in writing and duly executed by both of the parties hereto.

If assets of an employee benefit plan subject to any provision of the Employee Retirement Income Security Act of 1974 (“ERISA”) are intended to be used by either party hereto (the “Plan Party”) in a Transaction, the Plan Party shall so notify the other party prior to the Transaction. The Plan Party shall represent in writing to the other party that the Transaction does not constitute a prohibited transaction under ERISA or is otherwise exempt therefrom, and the other party may proceed in reliance thereon but shall not be required so to proceed.

This Annex III forms a part of the Master Securities Forward Transaction Agreement dated as of March 18, 2009 (the “Agreement”) between GMAC Investment Management LLC (“GMAC IM”) and GMAC Mortgage, LLC (“GMAC Mortgage”). Capitalized terms used but not defined in this Annex I shall have the meaning ascribed to them in the Agreement.

1. Definitions. For purposes of the Agreement and this Annex III, the following terms shall have the following meanings:

(a) “Forward Exposure”, the amount of loss a party would incur upon canceling a Transaction and entering into a replacement transaction, determined in accordance with market practice or as otherwise agreed by the parties;

(b) “Initial Margin Amount”, with respect to GMAC IM, means $0, and with respect to GMAC Mortgage, means $0 unless otherwise stated in the confirmation for a Transaction.

(c) “Minimum Transfer Amount”, $250,000 or such other specified dollar amount for a Transaction or Transactions agreed to by the parties (which amount shall be agreed to by the parties prior to entering into any such Transactions).

(d) “Net Forward Exposure”, the aggregate amount of a party’s Forward Exposure to the other party under all Transactions hereunder reduced by the aggregate amount of any Forward Exposure of the other party to such party under all Transactions hereunder;

(f) “Threshold”, with respect to GMAC IM, means $25,000,000, and with respect to GMAC Mortgage, means $0.

2. Margin Maintenance.

(a) If at any time a party (the “In-the-Money Party”) shall have a Net Unsecured Forward Exposure to the other party (the “Out-of-the-Money Party”) under one or more Transactions that exceeds the Threshold for the Out-of-the-Money Party, the In-the-Money Party may by notice to the Out-of-the-Money Party require the Out-of-the-Money Party to transfer to the In-the-Money Party cash collateral (together with any income thereon and proceeds thereof, “Forward Collateral”) sufficient to eliminate such Net Unsecured Forward Exposure. The Out-of-the-Money Party may by notice to the In-the-Money Party require the In-the-Money Party to transfer to the Out-of-the-Money Party Forward Collateral in an amount that exceeds the In-the-Money Party’s Net Forward Exposure (“Excess Forward Collateral Amount”).

(b) The parties agree, with respect to any or all Transactions hereunder, that the respective rights of the parties under subparagraph (a) of this Paragraph may be exercised only where the amount to be transferred in respect of a Net Unsecured Forward Exposure or Excess Forward Collateral Amount, as the case may be, exceeds the Minimum Transfer Amount.

Annex III-1

(c) The parties agree, with respect to any or all Transactions hereunder, that the respective rights of the parties under subparagraph (a) of this Paragraph to require the elimination of a Net Unsecured Forward Exposure or Excess Forward Collateral Amount, as the case may be, may be exercised whenever such a Net Unsecured Forward Exposure or Excess Forward Collateral Amount exists with respect to any single Transaction hereunder (calculated without regard to any other Transaction outstanding under the Agreement).

(d) The parties may agree, with respect to any or all Transactions hereunder, that (i) one party shall transfer to the other party Forward Collateral in an amount equal to a specified dollar amount or other specified threshold no later than a deadline agreed to by the parties in the relevant Confirmation, in Annex I to the Agreement or otherwise on the Trade Date for such Transaction or (ii) one party shall not be required to make any transfer otherwise required to be made under this Paragraph if, after giving effect to such transfer, the amount of the Forward Collateral held by such party would be less than a specified dollar amount or other specified threshold (which amount or threshold shall be agreed to by the parties prior to entering into any such Transaction).

(e) Unless otherwise agreed by the parties, if any notice is to be given by one party to the other under subparagraph (a) of this Paragraph, such notice shall be delivered by 11:00 a.m. (New York City time) on a Business Day. If such notice is so delivered by 11:00 a.m. (New York City time) on any Business Day, the party receiving such notice shall transfer Forward Collateral as provided in such subparagraph no later than 11:00 a.m. (New York City time) (in the case of a posting by GMAC Mortgage) or 1:00 p.m. (New York City time) (in the case of a posting by GMAC IM) on the next following Business Day.

(f) Unless otherwise agreed by the parties, GMAC IM may give notice by 3:00 p.m. (New York City time) on any Business Day to GMAC Mortgage that an Initial Margin Amount is required in respect of a Transaction. If such notice is so delivered by 3:00 p.m. (New York City time) on any Business Day, GMAC Mortgage shall transfer such Initial Margin Amount to GMAC IM no later than 11:00 a.m. (New York City time) on the next following Business Day.

(g) Upon the occurrence of the Settlement Date for any Transaction and the performance by the parties of their respective obligations to transfer cash on such date, the Initial Margin Amount, if any, and any Forward Collateral in respect of such Transaction, together with any income thereon and proceeds thereof, shall be transferred by the party holding such Initial Margin Amount or Forward Collateral to the other party; provided, however, that neither party shall be required to transfer such Initial Margin Amount or Forward Collateral to the other if such transfer would result in the creation of a Net Unsecured Forward Exposure of the transferor.

(h) A pledgor of Forward Collateral may not substitute Forward Collateral.

(i) Transfers of cash Forward Collateral or Initial Margin Amount shall be made in the same manner as the transfer of cash under Paragraph 5 of the Agreement.

3. Events of Default. In addition to the Events of Default set forth in Paragraph 7 of the Agreement, it shall be an additional “Event of Default” if either party fails, after one Business Day’s notice, to perform any covenant or obligation required to be performed by it under any provision of this Annex III.

Annex III-2

4. No Waivers, Etc. Without limitation of the provisions of Paragraph 14 of the Agreement, the failure to give a notice pursuant to subparagraph (a) through (f) of Paragraph 2 of this Annex III will not constitute a waiver of any right to do so at a later date.

5. Guarantee and Master Netting Agreement. The parties agree and acknowledge that the requirements of this Annex III may be fulfilled by the performance of the Guarantee and Master Netting Agreement attached as Annex V hereto.
