Common Stock Offering

On October 17, 2012, Walter Investment Management Corp. (the “Company”) entered into an underwriting agreement (the “Common Stock Underwriting Agreement”) with Credit Suisse Securities (USA) LLC, Morgan Stanley & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, and the other several underwriters named therein (collectively, the “Common Stock Underwriters”), related to a public offering (the “Common Stock Offering”) of 6,000,000 shares of the Company’s common stock, par value $0.01 per share, at a price of $42.00 per share. Pursuant to the terms of the Common Stock Underwriting Agreement, the Company granted the Common Stock Underwriters an option to purchase up to 900,000 shares of the Company’s common stock.

Convertible Senior Subordinated Notes Offering

Also on October 17, 2012, the Company entered into an underwriting agreement (the “Convertible Notes Underwriting Agreement”) with Credit Suisse Securities (USA) LLC, Morgan Stanley & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, and the other several underwriters named therein (the “Convertible Notes Underwriters” and, together with the Common Stock Underwriters, the “Underwriters”), related to a public offering (the “Convertible Notes Offering”) of $265.0 million aggregate principal amount of 4.50% Convertible Senior Subordinated Notes due 2019 (the “Convertible Notes”). Pursuant to the terms of the Convertible Notes Underwriting Agreement, the Company granted the Convertible Notes Underwriters an option to purchase up to $25.0 million aggregate principal amount of additional Convertible Notes.

The Convertible Notes will pay interest semi-annually on May 1 and November 1, commencing on May 1, 2013, at a rate of 4.50% per year, and will mature on November 1, 2019.

Prior to May 1, 2019, the Convertible Notes will be convertible only upon specified events and during specified periods, and, on or after May 1, 2019, at any time. The Convertible Notes will initially be convertible at a conversion rate of 17.0068 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $58.80, which is a 40% premium to the public offering price of the Company’s common stock in the Common Stock Offering. Upon conversion, the Company may pay or deliver, at its option, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock.

Certain of the Underwriters and their affiliates have provided in the past to the Company and the Company’s affiliates, and may provide from time to time in the future, various financial advisory and/or derivatives, commercial banking, investment banking and other commercial transactions and services for the Company and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions.
