Item 1.01 Entry into a Material Definitive Agreement

On February 1, 2013, Green Tree Servicing LLC (“Green Tree”), a wholly owned indirect subsidiary of Walter Investment Management Corp. (the “Company”), entered into a (i) Master Repurchase Agreement between The Royal Bank of Scotland plc (“RBS”) and Green Tree (the “Warehouse Agreement”) and (ii) Pricing Side Letter between RBS and Green Tree (“PSL”). In addition, pursuant to the terms of the Warehouse Agreement, the Company provided RBS with a guaranty (the “Guaranty”) in order to support Green Tree’s obligations under the Warehouse Agreement.

The Warehouse Agreement is structured as a master repurchase agreement, and provides for a maximum aggregate purchase price of $500,000,000. Of the $500,000,000 maximum aggregate purchase price, $200,000,000 is provided by RBS on a committed basis and $300,000,000 (collectively, the “Warehouse Facility”) is provided on an uncommitted basis. The Warehouse Facility matures on January 31, 2014. The Warehouse Facility will be used to support Green Tree’s funding obligations in connection with its residential mortgage loan origination business.

The Warehouse Agreement contains affirmative and negative covenants and representations and warranties customary for financings of this type and requires Green Tree to comply with certain financial covenants relating to liquidity, adjusted tangible net worth and leverage. Similarly, the Guaranty also contains covenants and representations and warranties customary for guaranties provided to support financings of this type and requires the Company to comply with the financial covenants contained in the Company’s Credit Agreement, which was entered into on November 28, 2012, among the Company, the lenders party thereto, Credit Suisse AG, as administrative agent and collateral agent, and the other parties party thereto.

The PSL contains economic terms relating to the Warehouse Facility (the “PSL Terms”) that the Company and RBS believe are proprietary to their business relationship and that, if disclosed, could adversely affect the Company’s and/or RBS’s competitive position within the repurchase facility marketplace. As a result of the proprietary nature of the PSL Terms, the Company has made a request to the Securities and Exchange Commission to treat the PSL Terms as confidential information. As a result of such request, the Company is filing a redacted version of the PLS as Exhibit 10.2 to this Current Report on Form 8-K.

Green Tree and RBS intend that the transactions under the Warehouse Facility be sales to RBS of the mortgage loans and not loans from RBS to Green Tree secured by the mortgage loans. However, in order to preserve RBS’s rights under the Warehouse Facility in the event a court or other forum recharacterizes the transactions as other than sales, as security for its obligations under the Warehouse Facility, Green Tree has also granted RBS a fully perfected first priority security interest in the mortgage loans purchased by RBS under the Warehouse Agreement, as well as all ancillary collateral relating to the purchased mortgage loans.

The foregoing description of the Warehouse Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Warehouse Agreement and a redacted version of the PSL which are filed as Exhibits 10.1 and 10.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The description of the Warehouse Agreement and PSL in Item 1.01 of this Current Report on Form 8-K, including the exhibits incorporated therein, are incorporated in their entirety into this Item 2.03 by reference.

Item 9.01 Financial Statements and Exhibits.
