ACI WORLDWIDE, INC.

Supplemental LTIP Performance Shares Agreement

2005 Equity and Performance Incentive Plan

(Amended by the Stockholders June 14, 2012 and further revised to reflect 3 for 1 stock

split effective July 10, 2014)

This Supplemental LTIP Performance Shares Agreement (this “Agreement”) is made as of the effective date set forth in Schedule A hereto (the “Effective Date”) between ACI Worldwide, Inc., a Delaware corporation (the “Corporation”) and the individual identified in Schedule A hereto, an employee of the Corporation or its Subsidiaries (the “Grantee”).

WHEREAS, the Board of Directors of the Corporation (the “Board of Directors”) has duly adopted, and the stockholders of the Corporation have approved, the 2005 Equity and Performance Incentive Plan, as amended (the “Plan”), which authorizes the Corporation to grant to eligible individuals performance shares, each such performance share being equal in value to one share of the Corporation’s common stock, par value of $0.005 per share (the “Common Shares”); and

WHEREAS, the Board of Directors has determined that it is desirable and in the best interests of the Corporation and its stockholders to approve a long-term incentive program and, in connection therewith, to grant the Grantee a certain number of performance shares, in order to provide the Grantee with an incentive to advance the interests of the Corporation, all according to the terms and conditions set forth herein and in the Plan.

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, the parties hereto do hereby agree as follows:

1. Grant of Performance Shares.

(a) Subject to the terms of the Plan, the Corporation hereby grants to the Grantee the number of performance shares (the “Performance Shares”) set forth in Schedule A, payment of which depends on the Corporation’s performance as set forth in this Agreement and in the Statement of Performance Goals attached hereto and incorporated herein by this reference (the “Statement of Performance Goals”) approved by the Compensation Committee of the Board of Directors (the “Committee”).

(b) The Grantee’s right to receive all or any portion of the Performance Shares will be contingent upon the achievement of certain management objectives (the “Management Objectives”), as set forth in the Statement of Performance Goals. The achievement of the Management Objectives will be measured during the performance period set forth on the Statement of Performance Goals.

(c) The Management Objectives for the Performance Period will be as set forth on the Statement of Performance Goals.

2. Earning of Performance Shares.

(a) Threshold Level Requirement. If, upon the conclusion of the Performance Period, any of the Management Objectives fall below the threshold levels set forth in the performance matrix contained in the Statement of Performance Goals (the “Performance Matrix”), none of the Performance Shares shall become earned.

(b) Earning Calculation. If, upon the conclusion of the Performance Period, the Management Objectives equal or exceed the threshold levels set forth in the Performance Matrix, a proportionate number of the Performance Shares shall become earned, as determined by mathematical interpolation and rounded up to the nearest whole share.

(c) Modification. If the Committee determines that a change in the business, operations, corporate structure or capital structure of the Corporation, the manner in which it conducts business or other events or circumstances render the Management Objectives to be unsuitable, the Committee may modify such Management Objectives or the related levels of achievement, in whole or in part, as the Committee deems appropriate; provided, however, that in the case of an award to a Covered Employee intended to qualify for an exemption under Section 162(m) of the Internal Revenue Code of 1986 (the “Code”), no such action may result in the loss of the otherwise available exemption of the award under Section 162(m).

(d) Conditions; Determination of Earned Award. Except as otherwise provided herein, the Grantee’s right to receive any Performance Shares is contingent upon his or her remaining in the continuous employ of the Corporation or a Subsidiary through the end of the Performance Period. For purposes of this Agreement, the continuous employ of the Grantee shall not be considered interrupted or terminated in the case of transfers between locations of the Corporation and its Subsidiaries. Following the Performance Period, with respect to Grantees that are Covered Employees, the Committee shall certify that the Management Objectives have been satisfied and shall determine the number of Performance Shares that shall have become earned hereunder. In all circumstances, the Committee shall have the ability and authority to reduce, but not increase, the amount of Performance Shares that become earned hereunder.

3. Retirement, Disability, Death or Termination without Cause. If the Grantee’s employment with the Corporation or a Subsidiary terminates following completion of the first full fiscal quarter of the Performance Period but before the payment of the Performance Shares as set forth in Section 6 below due to (a) the Grantee’s retirement approved by the Corporation, (b) Disability (as defined below), (c) death or (d) a termination by the Corporation without cause, the Corporation shall pay to the Grantee or his or her executor or administrator, as the case may be, at the time specified in Section 6, a number of Performance Shares equal to (i) the number of Performance Shares to which the Grantee would have been entitled under Section 2 above based on the performance of the Corporation for the full Performance Period, multiplied by (ii) a fraction, the

2

numerator of which is the number of full fiscal quarters the Grantee was employed during the Performance Period and the denominator of which is the number of full fiscal quarters in the Performance Period. The remaining Performance Shares shall be forfeited. For purposes of this Agreement, “Disability” means the Grantee’s permanent and total disability as defined in Section 22(e)(3) of the Code.

4. Other Termination. If the Grantee’s employment with the Corporation or a Subsidiary terminates before the payment of the Performance Shares as provided in Section 6 hereof for any reason other than as set forth in Section 3 above, the Performance Shares will be forfeited.

5. Leaves of Absence. If the Grantee was on short-term disability, long-term disability or unpaid leave of absence approved by the Corporation for more than thirty (30) consecutive calendar days during any fiscal quarter during Performance Period, the number of Performance Shares earned by the Grantee will be reduced such that the Grantee will only be entitled to (i) the number of Performance Shares to which the Grantee would have been entitled under Section 2 above based on the performance of the Corporation during the Performance Period, multiplied by (ii) a fraction, the numerator of which is the number of fiscal quarters the Grantee was employed during the Performance Period (excluding any fiscal quarters during which the Grantee was on a leave of absence for more than thirty (30) consecutive calendar days) and the denominator of which is the number of full fiscal quarters in the Performance Period.

6. Payment of Performance Shares. Payment of any Performance Shares that become earned as set forth herein will be made in the form of Common Shares, in cash, or in a combination of the two, as determined in the sole discretion of the Committee. Payment will be made as soon as practicable after the receipt of audited financial statements of the Corporation relating to the last fiscal year of the Performance Period and with respect to Covered Employees, the determination by the Committee of the level of attainment of the Management Objectives. Performance Shares will be forfeited if they are not earned at the end of the Performance Period and, except as otherwise provided in this Agreement, if the Grantee ceases to be employed by the Corporation or a Subsidiary at any time prior to such shares becoming earned.

7. Withholding of Taxes.

(a) The Grantee shall be liable for any and all federal, state, local or non-US taxes applicable to the Grantee, including, without limitation, withholding taxes, social security/national insurance contributions and employment taxes, arising out of this grant of Performance Shares, the issuance of Common Shares as payment for earned Performance Shares hereunder or the payment of cash for earned Performance Shares. In the event that the Corporation or the Grantee’s employer (the “Employer”) is required to withhold taxes as a result of the grant of the Performance Shares, the issuance of Common Shares as payment for earned Performance Shares or the payment of cash for earned Performance Shares, the Grantee shall at the election of the Corporation, in its sole discretion, either (i) surrender a sufficient number of whole Common Shares, having a Market Value

3

per Share on the date such Performance Shares become taxable equal to the amount of such taxes, or (ii) make a cash payment, as necessary to cover all applicable required withholding taxes and required social security/national insurance contributions on the date such Performance Shares become taxable, unless the Corporation, in its sole discretion, has established alternative procedures for such payment. If the number of shares required to cover all applicable withholding taxes and required social security/national insurance contributions includes a fractional share, then Grantee shall deliver cash in lieu of such fractional share. All matters with respect to the total amount to be withheld shall be determined by the Corporation in its sole discretion.

(b) Regardless of any action the Corporation or the Grantee’s Employer takes with respect to any or all income tax, social security/national insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), the Grantee acknowledges and agrees that the ultimate liability for all Tax-Related Items legally due by him is and remains the Grantee’s responsibility and that the Corporation and or the Employer (i) make no representations nor undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this grant of Performance Shares, including the grant of Performance Shares, the issuance of Common Shares as payment for earned Performance Shares, the payment of cash for earned Performance Shares or the subsequent sale of any Common Shares issued hereunder and receipt of any dividends; and (ii) do not commit to structure the terms or any aspect of this grant of Performance Shares to reduce or eliminate the Grantee’s liability for Tax-Related Items. The Grantee shall pay the Corporation or the Employer any amount of Tax-Related Items that the Corporation or the Employer may be required to withhold as a result of the Grantee’s participation in the Plan or the Grantee’s grant of Performance Shares, the Common Shares issued as payment for earned Performance Shares or the payment of cash for earned Performance Shares that cannot be satisfied by the means previously described above in Section 7(a). The Corporation may refuse to issue Common Shares as payment of earned Performance Shares related thereto if the Grantee fails to comply with the Grantee’s obligations in connection with the Tax-Related Items.

8. Forfeiture and Right of Recoupment. Notwithstanding anything contained herein to the contrary, by accepting these Performance Shares, Grantee understands and agrees that if (a) the Corporation is required to restate its consolidated financial statements because of material noncompliance due to irregularities with the federal securities laws, which restatement is due, in whole or in part, to the misconduct of Grantee, or (b) it is determined that the Grantee has otherwise engaged in misconduct (whether or not such misconduct is discovered by the Corporation prior to the termination of Grantee’s employment), the Board of Directors or a committee thereof (in each case, the “Board”) may take such action with respect to the Performance Shares as the Board, in its sole discretion, deems necessary or appropriate and in the best interest of the Corporation and its stockholders. Such action may include, without limitation, causing the forfeiture of unearned Performance Shares, requiring the transfer of ownership back to the

4

Corporation of Common Shares issued as payment for earned Performance Shares and still held by the Grantee, cash received by the Grantee as payment for earned Performance Shares and the recoupment of any proceeds from the sale of Common Shares issued as payment for Performance Shares earned pursuant to this Agreement. For purposes of this Section 8, “misconduct” shall mean a deliberate act or acts of dishonesty or misconduct which either (i) were intended to result in substantial personal enrichment to the Grantee at the expense of the Corporation or (ii) have a material adverse effect on the Corporation. Any determination hereunder, including with respect to Grantee’s misconduct, shall be made by the Board in its sole discretion. Notwithstanding any provisions herein to the contrary, Grantee expressly acknowledges and agrees that the rights of the Board set forth in this Section 8 shall continue after Grantee’s employment with the Corporation or its Subsidiary is terminated, whether termination is voluntary or involuntary, with or without cause, and shall be in addition to every other right or remedy at law or in equity that may otherwise be available to the Corporation.

9. Cash Dividends. Cash dividends on the Performance Shares covered by this Agreement shall be sequestered by the Corporation from and after the Effective Date until such time as any of such Performance Shares become earned in accordance with this Agreement, whereupon such dividends shall be converted into a number of Common Shares (based on the Market Value per Share on the date such Performance Shares become earned) to the extent such dividends are attributable to Performance Shares that have become earned. To the extent that Performance Shares covered by this Agreement are forfeited, all of the dividends sequestered with respect to such Performance Shares shall also be forfeited. No interest shall be payable with respect to any such dividends.

10. Non-Assignability. The Performance Shares and the Common Shares subject to this grant of Performance Shares are personal to the Grantee and may not be sold, exchanged, assigned, transferred, pledged, encumbered or otherwise disposed of by the Grantee until they become earned as provided in this Agreement; provided, however, that the Grantee’s rights with respect to such Performance Shares and Common Shares may be transferred by will or pursuant to the laws of descent and distribution or pursuant to a domestic relations order (within the meaning of Rule 16a-12 under the Securities Exchange Act of 1934, as amended). Any purported transfer or encumbrance in violation of the provisions of this Section 10, shall be void, and the other party to any such purported transaction shall not obtain any rights to or interest in such Performance Shares or Common Shares.

11. Adjustments. In the event of any change in the number of Common Shares by reason of a merger, consolidation, reorganization, recapitalization, or similar transaction, or in the event of a stock dividend, stock split, or distribution to shareholders (other than normal cash dividends), the Committee shall adjust the number and class of shares subject to outstanding Performance Shares and other value determinations applicable to outstanding Performance Shares. No adjustment provided for in this Section 11 shall require the Corporation to issue any fractional share.

12. Compliance with Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with the provisions of Section 409A of the

5

Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Grantee. This Agreement and the Plan shall be administered in a manner consistent with this intent.

13. Miscellaneous.

(a) The contents of this Agreement are subject in all respects to the terms and conditions of the Plan as approved by the Board of Directors and the stockholders of the Corporation, which are controlling. The interpretation and construction by the Board of Directors and/or the Committee of any provision of the Plan or this Agreement shall be final and conclusive upon the Grantee, the Grantee’s estate, executor, administrator, beneficiaries, personal representative and guardian and the Corporation and its successors and assigns. Unless otherwise indicated, the capitalized terms used in this Agreement shall have the same meanings as set forth in the Plan.

The terms and conditions of this Agreement may not be modified, amended or waived, except by an instrument in writing signed by a duly authorized executive officer at the Corporation. Notwithstanding the foregoing, no amendment shall adversely affect the Grantee’s rights under this Agreement without the Grantee’s consent.

14. Notices. Any notice hereunder by the Grantee to the Corporation shall be in writing and shall be deemed duly given (i) if mailed or delivered to the Corporation at its principal office, addressed to the attention of Stock Plan Administration, (ii) if electronically delivered to the e-mail address, if any, for Stock Plan Administration or (iii) if so mailed, delivered or electronically delivered to such other address or e-mail address as the Corporation may hereafter designate by notice to the Grantee. Any notice hereunder by the Corporation to the Grantee shall be in writing and shall be deemed duly given (i) if

6

mailed or delivered to the Grantee at Grantee’s address listed in the Corporation’s records, (ii) if electronically delivered to the e-mail address, if any, for Optionee listed in the Corporation’s records or (iii) if so mailed, delivered or electronically delivered to such other address or e-mail address as the Grantee may hereafter designate by written notice given to the Corporation.

15. Electronic Delivery and Acceptance. The Corporation may, in its sole discretion, decide to deliver any documents or notices related to current or future participation in the Plan by electronic means. By accepting the Performance Shares, electronically or otherwise, Grantee hereby consents to receive such documents or notices by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Corporation or a third party designated by the Corporation, including the use of electronic signatures or click-through acceptance of terms and conditions or other electronic means such as an e-mail acknowledgement.
