No. 6387-VCL (the “Action”), pending in the Court of Chancery of the State of Delaware (the “Court”).

WHEREAS, the parties to the Action intend to settle and resolve the claims asserted in the Action and have reached an agreement set forth in a Stipulation (attached hereto as Exhibit “A”), providing for the settlement of the Action on the terms and conditions set forth therein and subject to the approval of the Court.

WHEREAS, in the Stipulation, the Company, acting as depository, agreed, upon the earlier of: (a) ten business days after the Court’s entry of the Scheduling Order or (b) July 20, 2012, to pay or cause to be paid $10 million (the “Settlement Fund”) into an interest-bearing account established by counsel for Co-Lead Counsel for the Class.¹

WHEREAS, a third-party with rights related to the Recapitalization has agreed to return to MoneyGram those legal fees and expenses already paid by MoneyGram on its behalf, and/or waive pending reimbursements, as determined by MoneyGram, in a sum total of $750,000. MoneyGram will, in turn, contribute this $750,000 to the Settlement Fund.

NOW THEREFORE, the parties to this Supplemental Agreement have, in connection with the settlement set forth in the Stipulation, agreed as follows:

I.

TERMS AND CONDITIONS

1. Payment to the Plaintiffs. MoneyGram shall make the payments to the Settlement Fund described in Paragraph 1 of the Stipulation, with the sole exception that Federal shall contribute $2,750,000 of the $10,000,000 directly to the Settlement Fund, on behalf of the Individual Defendants and MoneyGram pursuant to its coverage obligations under Federal Policy No. 8209-8703.

2. THL Contribution. As members of the MoneyGram Board of Directors, Hagerty, Rao, Jaeckel, and Lawry (the “THL Directors”) are entitled to receive annual compensation. Currently that compensation consists of an annual cash retainer of $90,000, and an equity award of restricted stock units valued at $90,000. Fees earned by the THL Directors, as well as reimbursements for Board-related expenses, are paid directly to THL Managers VI, LLC. These payments and restricted stock awards to directors are expected to continue for the foreseeable future. In consideration of MoneyGram’s payment to the Settlement Fund as set forth in Paragraph 1 hereof, THL and the THL Directors agree to waive all future rights to receive cash or equity compensation from MoneyGram for service by these Directors, or any other Directors appointed by THL, for service on the MoneyGram Board. MoneyGram has valued this waiver at a minimum of $2,000,000.

3. Goldman Waiver of Reimbursement. Pursuant to Section 6.15 of the Recapitalization Agreement, MoneyGram, among other things, is required to pay GS Investors’ reasonable legal fees and expenses in connection with any legal proceedings involving the Recapitalization. In consideration of MoneyGram’s payment to the Settlement Fund as set forth in Paragraph 1 hereof, Goldman agrees not to seek reimbursement of $1,000,000 of the overall total reasonable legal fees and expenses that have been or may be incurred by the GS Investors in connection with the Action. The GS Investors shall be entitled to seek reimbursement of reasonable fees and expenses over that amount.

4. Contingent on Final Judgment. In the event that the Conditions of Settlement set forth in Paragraph 11 of the Stipulation are not met, then all of the parties shall proceed in all respects as if the Stipulation and this Supplemental Agreement had not been executed, any and all funds paid into the Settlement Fund shall revert back to the contributor(s) of such funds, all waivers and agreements herein shall be deemed null and void, and any rights of reimbursement or compensation shall remain in place notwithstanding the terms hereof.
