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.

5. No Amendments. This Supplemental Agreement may not be amended nor
may any of its provisions be waived except by a writing signed by all of the parties hereto.

6. Counterparts. This
Supplemental Agreement may be executed in counterparts and transmitted by facsimile, via e-mail as a PDF file, or as an original signature by any of the signatories hereto, and as so executed shall constitute one agreement.

accordance with, the Laws of the State of Delaware, without regard to conflict of law principles. Any dispute arising out of or relating to this Supplemental Agreement shall be filed and litigated exclusively in the Court, which shall retain
jurisdiction over the parties and all such disputes. The parties expressly waive any right to demand a jury trial, and consent to service of process upon their attorneys by registered mail, in connection with any dispute brought in accordance with
this paragraph.

8. Execution Authority. Each of the attorneys executing this Supplemental Agreement has been duly
