Memorandum Agreement, dated September 24, 2013, between Freddie Mac and James Mackey

Exhibit 10.1

On behalf of Freddie Mac’s Board of Directors (the “Board”), this memorandum sets forth Freddie Mac’s agreement to employ you as its Executive Vice President and Chief Financial Officer, effective no later than December 2, 2013, pursuant to the terms and conditions set forth herein. The terms and conditions set forth herein have been approved by the Board and the Federal Housing Finance Agency (“FHFA”) and supersede any previous communications you may have had with Freddie Mac, FHFA, or the United States Department of Treasury (“Treasury”).

As Freddie Mac’s Executive Vice President and Chief Financial Officer, you shall report to me, Freddie Mac’s Chief Executive Officer, or my successor, and have the same status, privileges, and responsibilities normally inherent in such capacity in corporations of similar size and character. You shall also perform such additional duties as the Board may from time to time reasonably assign to you.

During your employment, you agree to devote substantially all of your time, attention, and energies to Freddie Mac’s business, and to not be engaged in any other business activity unless permitted under our Outside Employment and Other Outside Activities Policy. This restriction shall not prevent you from devoting a reasonable amount of time to charitable or public interest activities or from making passive investments of your assets in such form or manner as you desire, consistent with Freddie Mac’s Personal Securities Investment policy.

You also agree to use your best efforts to reactivate your certified public accountant license within six months of your hire date.

In the event that you do not agree to the terms of either or both documents, you will be paid only Base Salary.

Your target total direct compensation (“Target TDC”) will be $3,000,000, which will be pro-rated in the first calendar year of employment based on your agreed upon hire date. Your Target TDC will consist of two components – Base Salary and Deferred Salary – which are summarized below.
