THIS AMENDMENT NO. 1 TO CREDIT AGREEMENT (this “Amendment”) dated as of May 23, 2008, by and among GLOBAL PAYMENTS INC., a Georgia corporation, (the “Company”), the banks and other financial institutions listed on the signature pages thereof, as lenders (the “Lenders”), and JPMORGAN CHASE BANK, N.A., as Administrative Agent (the “Administrative Agent”).

W I T N E S S E T H:

WHEREAS, the Company, the Lenders, and the Administrative Agent are parties to a certain Credit Agreement dated as of November 16, 2006 (the “Credit Agreement”; capitalized terms used in this Amendment without definition that are defined in the Credit Agreement having the meanings in this Amendment as specified for such capitalized terms in the Credit Agreement);

WHEREAS, the Company and the Lenders have agreed to amend the Credit Agreement in certain respects as set forth in this Amendment;

NOW, THEREFORE, for and in consideration of the mutual covenants contained herein and other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

SECTION 1. Amendments to Credit Agreement. Subject to the satisfaction of the conditions precedent set forth in Section 2 hereof, and effective as of the Effective Date (as hereinafter defined), the Credit Agreement shall be amended as follows:

1.1 Section 1.01 of the Credit Agreement is hereby amended by (i) adding the new defined terms “Joint Venture Call Right” and “Designated Subsidiaries” and accompanying definitions, and (ii) deleting the definition for the defined term “Net Income” and substituting in lieu thereof the definition set forth below, in each case in appropriate alphabetical order, as follows:

“Designated Subsidiary” means a non-wholly owned Subsidiary of the Company that is subject to an encumbrance or restriction of the type described in clause (E) of Section 6.08.

“Joint Venture Call Right” means, with respect to the Person (other than any Affiliate of the Company) owning the minority of the outstanding Equity Interests in a non-wholly owned Subsidiary of the Company, the contractual right of such Person to purchase, and to require such Subsidiary to sell, all or a portion of the assets of, or all or a portion of the outstanding Equity Interests in, such Subsidiary to such Person or its Affiliate.

“Net Income” means, for any period, net income of the Company and its Consolidated Subsidiaries for such period determined on a consolidated basis in

accordance with GAAP, but excluding therefrom (to the extent included therein) (a) any earnings of Designated Subsidiaries and any equity interests in the earnings of joint ventures or other Persons that are not Subsidiaries, in each case to the extent such earnings are not actually paid in cash, and the Company or its Subsidiaries do not have the ability to cause such earnings to be paid in cash, to the Company or its Subsidiaries (other than Designated Subsidiaries) with respect to such period, and (b) the after-tax impact of Non-Recurring Non-Cash Items. Further, Non-Recurring Cash Items will only be reflected (on an after-tax basis) in net income as such amounts are paid, and the cash portions of any restructuring charge will only be reflected (on an after-tax basis) in net income for pre-tax amounts that exceed the Restructuring Charge Limit.

1.2 Section 6.03 of the Credit Agreement is hereby amended by deleting subsection (e) of said Section 6.03 in its entirety and substituting in lieu thereof the following subsection (e):

(e) so long as no Event of Default shall then have occurred and be continuing or would result therefrom, the Company and its Subsidiaries may effect any Asset Sale so long as the assets to be sold pursuant to all such Asset Sales during any Fiscal Year have not contributed, in the aggregate, more than fifteen percent (15%) of the EBITDA of the Company for the then-most recently completed period of four consecutive Fiscal Quarters for which financial statements are available (with the determination of such contribution to EBITDA to be made by the Company in a manner reasonably acceptable to the Administrative Agent); provided, however, that in determining the Company’s compliance with the foregoing limitation on Asset Sales in any Fiscal Year, the Company may deduct from the EBITDA attributable to the assets sold in such Asset Sales, an amount equal to the EBITDA attributable to Permitted Acquisitions made or proposed to be made by the Company and its Subsidiaries within 180 days after consummation of the respective Asset Sale and with the proceeds of such Asset Sale (with the determination of the EBITDA attributable to such Permitted Acquisition to be made by the Company in a manner reasonably acceptable to the Administrative Agent); and provided, further; that if and to the extent, absent such deduction with respect to such proposed Permitted Acquisitions, a breach of this Section 6.03(e) would occur, the Company shall provide the Administrative Agent, not later than the expiration of such 180-day period, a report in reasonable detail as to such proposed Permitted Acquisitions, if any, and to the extent all or any portion of the proposed Permitted Acquisitions (or any other Permitted Acquisitions) are not so made within such 180 day period, then only the EBITDA attributable to Permitted Acquisitions made shall be deducted for purposes of determining whether the Company is in compliance with the 15% limitation set forth above for the Fiscal Year during which such Asset Sales occurred;

-2-

1.3 Section 6.03 of the Credit Agreement is hereby amended by (i) deleting the “.” and substituting “; and” at the end of subsection (f) thereof, and (ii) adding a new subsection (g) to said Section 6.03, as follows:

(g) any Asset Sale made as a result of the exercise of the Joint Venture Call Right with respect to the assets or Equity Interests of the Subsidiary that are subject to such Joint Venture Call Right; provided, however, that if after giving effect to such Asset Sale, the Company’s Leverage Ratio (computed on a pro forma basis as of the last day of the most recently ended period of four consecutive Fiscal Quarters for which financial statements are available) would exceed 2.00 to 1.00, then the Company shall, not later than ten (10) Business Days after such Asset Sale is consummated, provide written notice thereof to the Administrative Agent and, unless such prepayment is waived in writing by the Administrative Agent (acting at the direction of the Required Lenders) within ten (10) Business Days after its receipt of such notice, the Company shall prepay or cause to be prepaid an amount of its outstanding Indebtedness in the form of term loans used to finance the purchase of the assets subject to such Asset Sale (with payment to be applied pro rata across maturities) or, if no such term loans are then outstanding, Indebtedness under this Agreement or any other Indebtedness (but without any required reduction in the commitments from the lenders that are parties to any revolving credit facilities) equal to the lesser of (x) the amount necessary to be prepaid to reduce such Leverage Ratio to 2.00 to 1.00, (y) the net cash proceeds received by the Company and its Subsidiaries from such Asset Sale (after giving effect to any costs, fees and expenses associated therewith and any Indebtedness repaid in connection therewith), and (z) the total amount of Indebtedness then outstanding as term loans used to finance the purchase of the assets subject to such Asset Sale and advances under this Agreement.

1.4 Section 6.08 of the Credit Agreement is hereby amended by (i) deleting the word “and” preceding clause (D) thereof, (ii) deleting the “.” immediately following clause (D), and (iii) adding the following clause (E) at the end of Section 6.08:

, and (E) any such encumbrance or restriction pursuant to an agreement between the Company or its Subsidiary with the Person (other than any Affiliate of the Company) owning the minority of the outstanding Equity Interests in a non-wholly owned Subsidiary of the Company requiring the consent of such Person prior to taking the actions described in the preceding clauses (i), (ii) or (iii) above with respect to such non-wholly owned Subsidiary.
