Common Stock Offering

On October 23, 2012, Walter Investment Management Corp. (the “Company”) closed the underwritten public offering (the “Common Stock Offering”) of 6,900,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), which amount included the 900,000 shares issued pursuant to the exercise by the Common Stock Underwriters (as defined below) of their option to purchase additional shares pursuant to the underwriting agreement, dated October 17, 2012, by and among the Company and 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”).

Convertible Senior Subordinated Notes Offering

Also on October 23, 2012, the Company closed the underwritten public offering (the “Convertible Notes Offering”) of $290.0 million aggregate principal amount of 4.50% Convertible Senior Subordinated Notes due 2019 (the “Notes”), which amount included $25.0 million aggregate principal amount of the Notes issued pursuant to the exercise by the Convertible Notes Underwriters (as defined below) of their option to purchase additional Notes pursuant to the underwriting agreement, dated October 17, 2012, by and among the Company and 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”).

The net proceeds of the Convertible Notes Offering (before offering expenses payable by the Company) of $281.3 million and $15.4 million of cash on hand were used to repay in full all indebtedness outstanding under the Second Lien Credit Agreement, dated July 1, 2011, among the Company, the lenders, Credit Suisse AG and the other parties party thereto and accrued interest, certain fees and expenses and a prepayment premium of $29.4 million in connection therewith. The Second Lien Credit Agreement would have matured on December 31, 2016 and bore an interest rate equal to LIBOR plus 1100 basis points per annum, with a LIBOR floor equal to 150 basis points. Borrowings under the second lien senior secured term loan thereunder had a weighted average interest rate of 12.50% for the six months ended June 30, 2012.

The Notes were issued pursuant to the Subordinated Indenture, dated as of January 13, 2012 (the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of October 23, 2012 (the “Supplemental Indenture”, together with the Base Indenture, the “Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee.

The 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 5:00 p.m., New York City time, on the business day immediately preceding May 1, 2019, the Notes will be convertible only under the following circumstances: (1) during any calendar quarter commencing after December 31, 2012 (and only during such calendar quarter), if the last reported sale price of the Common Stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the Indenture) per $1,000 principal amount of notes for each trading day of such measurement period was less than 98% of the product of the last reported sale price of the Common Stock and the applicable conversion rate on such trading day; or (3) upon the occurrence of certain corporate events specified in the Indenture. On or after May 1, 2019, until 5:00 p.m., New York City time, on the second business day immediately preceding the maturity date, the Notes will be convertible at any time.

Upon conversion, the Company may pay or deliver, at its option, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock. The conversion rate will initially be 17.0068 shares of Common Stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $58.80 per share of Common Stock). The conversion rate will be subject to adjustment in certain events but will not

2

be adjusted for accrued and unpaid interest, if any. In addition, following certain corporate events, the Company will increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event in certain circumstances.

The Company may not redeem the Notes prior to the maturity date.

Upon a “fundamental change,” (as defined in the Indenture) holders will have the option to require the Company to repurchase the Notes for cash, as long as such repurchase is not prohibited under any then-outstanding credit facility of the Company or the Company has obtained the necessary consents and waivers thereunder, at a price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain fundamental changes, the Company will increase the conversion rate for a holder who converts its Notes in connection with that fundamental change.

The Indenture contains customary events of default, including, among other things, payment default, conversion default, failure to provide certain notices under the Indenture and certain provisions related to bankruptcy events.

The Indenture provides that the Company may not consolidate with or merge with or into any other person, and may not sell, transfer, lease or convey all or substantially all of our consolidated properties and assets, taken as a whole, to another person, unless: (a) the resulting, surviving or transferee person (if not the Company) is a corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and such corporation (if not the Company) expressly assumes by a supplemental indenture all of the Company’s obligations under the Notes and the Indenture, (b) immediately after giving effect to the transaction described above, no default or event of default, has occurred and is continuing; and (c) the Company has delivered to the trustee an officer’s certificate and opinion of counsel in accordance with the Indenture.
