FIRST INCREMENTAL AMENDMENT AND JOINDER AGREEMENT (this “ Agreement ”) dated as of November 14, 2011 relating to the Credit Agreement dated as of May 18, 2011 (the “ Credit Agreement ”) among MoneyGram International, Inc., a Delaware corporation (“ Holdco ”), MoneyGram Payment Systems Worldwide, Inc., a Delaware corporation (the “ Borrower ”), the Lenders from time to time party thereto and Bank of America, N.A., a national banking association, as LC Issuer, as the Swing Line Lender, as Administrative Agent (in such capacity, the “ Administrative Agent ”) and as Collateral Agent.

RECITALS:

The Borrower has, by notice (the “ Incremental Notice ”) to the Administrative Agent dated November 8, 2011 delivered pursuant to Section 2.25(a) of the Credit Agreement (a copy of which notice has been delivered to the Lenders and is attached as Exhibit A hereto), requested Incremental Term Loans in an aggregate principal amount of up to $150,000,000. Each financial institution identified on the signature pages hereto (or that becomes party hereto prior to the Tranche B-1 Funding Date (as defined below) through a joinder to this Agreement in the form of Exhibit B hereto (an “ Additional Joinder ”)) as a “Tranche B-1 Lender” (each, a “ Tranche B-1 Lender ”) agrees severally, on the terms and conditions set forth herein and in the Credit Agreement, to provide an Incremental Term Loan (the aggregate principal amount of such Incremental Term Loans not to exceed the amount set forth herein) and to become, if not already, a Lender for all purposes under the Credit Agreement.

The parties hereto therefore agree as follows:

SECTION 1 . Defined Terms. Unless otherwise specifically defined herein, each term used herein that is defined in the Credit Agreement has the meaning assigned to such term in the Credit Agreement.

SECTION 2 . Making the Incremental Term Loans . (a) Each Tranche B-1 Lender severally (and not jointly) agrees, on the terms and subject to the conditions set forth in this Agreement, to make an Incremental Term Loan (each, a “ Tranche B-1 Loan ”) to the Borrower on the Tranche B-1 Funding Date in the amount set forth opposite such Incremental Term Lender’s name in Schedule 1 to this Agreement under the caption “Tranche B-1 Commitment” (or, in the case of any Tranche B-1 Lender that becomes party hereto through an Additional Joinder, as set forth in its Additional Joinder) (its “ Tranche B-1 Commitment ”). The Tranche B-1 Loans shall constitute a separate Class of Term Loans under the Credit Agreement, distinct from the Class of Term Loans made by the Lenders on the Effective Date. No amount of any Tranche B-1 Loan which is repaid or prepaid by the Borrower may be reborrowed hereunder. Not later than 1:00 p.m., New York City time, on the Tranche B-1 Funding Date, each Tranche B-1 Lender shall make available funds equal to its Tranche B-1 Commitment in immediately available funds to the Administrative Agent at its address specified pursuant to Article 13 of the Credit Agreement. Gross proceeds required to be funded by each Tranche B-1 Lender with respect to its Tranche B-1 Loan shall be equal to 97.75% of the principal amount of such Tranche B-1 Loan.

(b) The following amendments are made to Sections 1.01 and 2.01 of the Credit Agreement to reflect the foregoing:

(i) Section 1.01: The following new defined terms are added to Section 1.01 in appropriate alphabetical order:

“ First Incremental Agreement ” means the First Incremental Amendment and Joinder Agreement dated as of November 14, 2011 among Holdco, the Borrower, the Tranche B-1 Lenders identified therein and the Administrative Agent.

“ Tranche B-1 Commitment ” means, for each Tranche B-1 Lender, the amount as defined therefor in the First Incremental Agreement.

“ Tranche B-1 Funding Date ” means the date on which the Tranche B-1 Loans are made (if at all) pursuant to the First Incremental Agreement.

“ Tranche B-1 Lender ” means the “Tranche B-1 Lenders” identified in and party to the Incremental Agreement.

“ Tranche B-1 Loan ” has the meaning set forth in Section 2.01.

For the avoidance of doubt, the “Applicable Margin” and “Maturity Date” for each Tranche B-1 Loan shall be as provided for all Term Loans in the Credit Agreement as in effect on the date hereof.

(ii) Section 2.01: The existing text of Section 2.01 of the Credit Agreement is designated to be clause “(a)” thereof, and the following new clause (b) is added to read in full as follows:

(b) Each Tranche B-1 Lender severally (and not jointly) agreed, on the terms and subject to the conditions set forth in the First Incremental Agreement, to make an Incremental Term Loan (each, a “ Tranche B-1 Loan ”) to the Borrower on the Tranche B-1 Funding Date in the amount of such Tranche B-1 Lender’s Tranche B-1 Commitment. The Tranche B-1 Loans shall constitute a separate Class of Term Loans under the Credit Agreement, distinct from the Class of Term Loans made by the Lenders on the Effective Date. No amount of any Tranche B-1 Loan which is repaid or prepaid by the Borrower may be reborrowed hereunder. Not later than 1:00 p.m., New York City time, on the Tranche B-1 Funding Date, each Tranche B-1 Lender shall make available funds equal to its Tranche B-1 Commitment in immediately available funds to the Administrative Agent at its address specified pursuant to Article 13 of the Credit Agreement.

The Borrower shall repay to the Administrative Agent for the ratable account of the applicable Tranche B-1 Lender, (i) on the last Business Day of each March, June, September and December, commencing with the last Business Day of December 2011, an amount equal to 0.25% of the aggregate principal amount of the Tranche B-1 Loans outstanding on the Tranche B-1 Funding Date (which payments shall be reduced as a result of the application of prepayments in accordance with the order of priority set forth in Section 2.10(a)) and (ii) on the Term Loan Maturity Date, the aggregate principal amount of such Tranche B-1 Loans outstanding on such date, together in each case with accrued and unpaid interest on the principal amount to be paid to but excluding the date of such payment.

(b) Each of the Loan Parties has the power and authority and legal right to execute and deliver this Agreement and to perform its obligations under the Loan Documents to which it is a party (in each case in this Section 6, as amended by this Agreement). The execution and delivery by each of the Loan Parties of this Agreement and the performance of its obligations under the Loan Documents to which it is a party have been duly authorized by proper corporate or other organizational proceedings, and the Loan Documents to which each such Loan Party is a party constitute legal, valid and binding obligations of such Loan Party enforceable against such Loan Party in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally or by general equitable principles.

(c) Neither the execution and delivery by any Loan Party of this Agreement, nor the consummation of the transactions contemplated by the Loan Documents, nor compliance with the provisions thereof will violate (x) any applicable law, rule, regulation, ruling, order, writ, judgment, injunction, decree or award binding on Holdco or any of its Subsidiaries or any Property of such Person or (y) Holdco’s or any Material Domestic Subsidiary’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by laws, or operating or other management agreement, or substantially equivalent governing document, as the case may be, or (z) the provisions of any note, bond, mortgage, deed of trust, license, lease indenture, instrument, agreement or other obligation (each a “ Contract ”) to which Holdco or any Subsidiary is a party or is subject, or by which it, or its Property, is bound, or conflict with, result in a breach of any provision thereof or constitute a default thereunder (or result

No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by Holdco or any of its Material Domestic Subsidiaries, is required to be obtained by Holdco or any of its Material Domestic Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under this Agreement, the payment and performance by the Borrower of the Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents.
