Letter Agreement with Birch Run

On November 16, 2015, Walter Investment Management Corp., a Maryland corporation (the “Company”), entered into a letter agreement with Birch Run Capital Advisors, LP (“Birch Run”) and Daniel Beltzman, the managing member of the general partner of Birch Run. Birch Run is one of the Company’s largest stockholders having beneficial ownership of 7,474,587 shares of the Company’s common stock, as set forth in Birch Run’s Form 13F, filed with the SEC on November 16, 2015.

Pursuant to the letter agreement, effective as of December 7, 2015, the size of the board of directors of the Company (the “Board”) will be increased and Mr. Beltzman will be appointed to serve as a Class III director on the Board with his term expiring at the Company’s 2018 annual meeting of stockholders. Birch Run and Mr. Beltzman have also agreed to vote all of their stock, at the Company’s 2016 annual meeting of stockholders, in support of each director nominated by the Board who is currently a Class I director, and against any stockholder recommendations and proposals not approved by the Board.

The letter agreement also notes that the Board plans to identify and appoint a new non-management director as soon as practicable and to transition the Board back to its current size of nine directors on or before the 2017 annual stockholders meeting. The Board will look to work with Mr. Beltzman on these matters following his appointment.

Mr. Beltzman has agreed, upon becoming a member of the Board, to be subject to the same governance and confidentiality policies and shall be entitled to the same insurance, indemnification, compensation and expense reimbursement programs that apply to all non-employee directors of the Company.

The foregoing summary of the letter agreement is not complete and is subject to, and qualified in its entirety by, the text of the letter agreement, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

Amendment of Rights Agreement

On November 16, 2015, the Company and Computershare Trust Company, N.A., a federally chartered trust company, as Rights Agent (the “Rights Agent”) entered into Amendment No. 1 (the “Amendment”) to the Rights Agreement, dated as of June 29, 2015 (the “Rights Agreement”) and to which the Company and the Rights Agent were parties.

Upon the terms and subject to the conditions set forth in the Rights Agreement and the Amendment, (i) Birch Run and its affiliates and associates may acquire up to 25% of the total voting power of all shares of the Company’s common stock without triggering the exercisability of the preferred share purchase rights attached to shares of the Company’s common stock pursuant to the Rights Agreement, and (ii) shares of the Company’s common stock received by directors as compensation for their services, pursuant to any director compensation program of the Company, will also not trigger the exercisability of such rights.
