2005 Equity and Performance Incentive Plan

(Amended by the Stockholders July 24, 2007)

This Stock Option Agreement (the “Option Agreement”) is made as of                         , by and between ACI Worldwide, Inc., a Delaware corporation (the “Corporation”), and [                                    ], an employee of the Corporation or its Subsidiaries (the “Optionee”).

WHEREAS, the Board of Directors of the Corporation has duly adopted, and the stockholders of the Corporation have approved, the 2005 Equity and Performance Plan, as amended (the “Plan”), which Plan authorizes the Corporation to grant to eligible individuals options for the purchase of shares of the Corporation’s Common Stock (the “Stock”); and

WHEREAS, the Board of Directors of the Corporation has determined that it is desirable and in the best interests of the Corporation and its stockholders to grant the Optionee an option to purchase a certain number of shares of Stock, in order to provide the Optionee with an incentive to advance the interests of the Corporation, all according to the terms and conditions set forth herein.

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

1.                            GRANT OF NON-QUALIFIED STOCK OPTION

Subject to the terms of the Plan, the Corporation hereby grants to the Optionee the right and option (the “Option”) to purchase from the Corporation, on the terms and subject to the conditions set forth in this Option Agreement, [                    ] shares of Stock (the “Option Shares”).  The Date of Grant of this Option is                             .  This Option shall not constitute an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”).

2.                            TERMS OF PLAN

The Option granted pursuant to this Option Agreement is granted subject to the terms and conditions set forth in the Plan, a copy of which has been delivered to the Optionee.  All terms and conditions of the Plan, as may be amended from time to time, are hereby incorporated into this Option Agreement by reference and shall be deemed to be a part of this Option Agreement, without regard to whether such terms and conditions (including, for example, provisions relating to certain changes in capitalization of the Corporation) are otherwise set forth in this Option Agreement.  In the event that there is any inconsistency between the provisions of this Option Agreement and of the Plan, the provisions of the Plan shall govern.  Capitalized terms used herein that are not otherwise defined shall have the meaning ascribed to them in the Plan.

The exercise price for the shares of Stock subject to the Option granted by this Option Agreement is $               per share (the “Exercise Price”).

4.                            EXERCISE OF OPTION

Subject to the provisions of the Plan and subject to the earlier expiration or termination of this Option in accordance with its terms, the Option granted pursuant to this Option Agreement shall be exercisable only as follows:

4.1                               Time of Exercise of Option

4.1.1                      The Option shall become exercisable with respect to the Option Shares only as follows:  One-quarter of the Option Shares ([                ] Option Shares) shall become exercisable on each of the first four anniversaries of the Date of Grant if the Optionee shall have remained in the continuous employ of the Corporation or any of its Subsidiaries as of each such date.

4.1.2                      Notwithstanding Section 4.1.1 above, in accordance with the provisions of the Plan, if the Optionee ceases to be an employee of the Corporation or a Subsidiary of the Corporation by reason of Disability (as defined in Section 4.3.2 below), the unexercised portion of any Option held by such Optionee at that time will become immediately vested and will be exercisable until terminated in accordance with Section 4.3 below.

4.1.3                      Notwithstanding Section 4.1.1 above, in accordance with the provisions of the Plan, if the Optionee dies while employed by the Corporation or a Subsidiary of the Corporation (or dies within a period of one month after ceasing to be an employee for any reason other than Disability or within a period of one year after ceasing to be an employee by reason of Disability), the unexercised portion of any Option held by such Optionee at the time of death will become immediately vested and will be exercisable until terminated in accordance with Section 4.3 below.

[4.1.4                  Notwithstanding Section 4.1.1 above, in accordance with the provisions of the Plan, the Option granted under this Option Agreement shall become immediately exercisable upon the occurrence, after the Date of Grant, of a Change in Control (as defined in Section 10 below) if the Optionee is an employee of the Corporation or any Subsidiary on the date of the consummation of such Change in Control.]

4.2                               Limitations

The portion of the Option that has not become exercisable as of the date of the Optionee’s termination of employment with the Corporation or any of its Subsidiaries for any reason shall automatically terminate as of the date of the Optionee’s termination of employment with the

2

Corporation or its Subsidiaries and shall not become exercisable after such termination.  To the extent the Option is exercisable, it may be exercised, in whole or in part; provided, that no single exercise of the Option shall be for less than 100 shares, unless at the time of the exercise, the maximum number of shares available for purchase under this Option is less than 100 shares.  In no event shall the Option be exercised for a fractional share.

4.3                               Termination of Option

This Agreement and the Option granted hereby shall terminate automatically and without further notice on the earliest of the following dates:

4.3.1                       90 calendar days from the date of the Optionee’s termination of employment with the Corporation or a Subsidiary for any reason other than death or Disability (as defined below);

4.3.2                       one year after the Optionee’s permanent and total disability as defined in Section 22(e)(3) of the Code (“Disability”);

4.3.3                       one year after the Optionee’s death, if such death occurs (i) while the Optionee is employed by the Corporation or a Subsidiary, (ii) within the 90-day period following the Optionee’s termination of employment for any reason other than Disability; or (iii) within the one-year period following the Optionee’s termination of employment by reason of the Optionee’s Disability; or

4.3.4                       ten years from the Date of Grant.

The Corporation shall have the authority to determine the date an Optionee ceases to be an employee by reason of Disability.  In the case of death, the Option may be exercised by the executor or administrator of the Optionee’s estate or by any person or persons who shall have acquired the Option directly from the Optionee by bequest or inheritance.  The Optionee shall be deemed to be an employee of the Corporation or any Subsidiary if on a leave of absence approved by the Board of Directors of the Corporation and the continuous employment of the Optionee with the Corporation or any of its Subsidiaries will not be deemed to have been interrupted, and the Optionee shall not be deemed to have ceased to be an employee of the Corporation or its Subsidiaries, by reason of the transfer of the Optionee’s employment among the Corporation and its Subsidiaries.

4.4                               Limitations on Exercise of Option

In no event may the Option be exercised, in whole or in part, after the occurrence of an event which results in termination of the Option, as set forth in Section 4.3 above.  The Option shall not be exercisable if and to the extent the Corporation determines such exercise or method of exercise would violate applicable securities laws, the rules and regulations of any securities exchange or quotation system on which the Stock is listed, or the Corporation’s policies and procedures.

4.5                               Method of Exercise of Option

4.5.1                      To the extent then exercisable, the Option may be exercised in whole or in part by written notice to the Corporation stating the number of shares for which the Option is being exercised and the intended manner of payment.  The date of such notice shall be the exercise date.  Payment equal to the aggregate Exercise Price of the shares shall be payable (i) in cash in the form of currency or check or other cash equivalent acceptable to the Corporation, (ii) by actual or constructive transfer to the Corporation of nonforfeitable, outstanding shares of Stock that have been owned by the Optionee for at least six months prior to the date of exercise,  (iii) by any combination of the foregoing methods of payment or (iv) in accordance with such other method or manner as set forth below.

                (A)          Cash Exercise (to exercise and retain the Option Shares):  Subject to the terms and conditions of this Option Agreement and the Plan, the Option may be exercised by delivering written notice of exercise to the Corporation, at its principal office, addressed to the attention of Stock Plan Administration, or to the agent/broker designated by the Corporation, which notice shall specify the number of shares for which the Option is being exercised, and shall be accompanied by payment in full of the Exercise Price of the shares for which the Option is being exercised plus the full amount of all applicable withholding taxes due on the Option exercise.  Payment of the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option shall be made either in cash or by certified check payable to the order of the Corporation.  If the person exercising the Option is not the Optionee, such person shall also deliver with the notice of exercise appropriate proof of his or her right to exercise the Option, as the Corporation may require in its sole discretion.  Promptly after exercise of the Option as provided for above, the Corporation shall deliver to the person exercising the Option a certificate or certificates for the shares of Stock being purchased.

                (B)           Same-Day-Sale Exercise (to exercise and immediately sell all the Option Shares):  Subject to the terms and conditions of this Option Agreement and the Plan, the Option may be exercised by delivering written notice of exercise to the agent/broker designated by the Corporation, which notice shall specify the number of shares for which the Option is being exercised and irrevocable instructions to promptly (1) sell all of the shares of Stock to be issued upon exercise and (2) remit to the Corporation the portion of the sale proceeds sufficient to pay the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option and all applicable taxes due on the Option exercise.  The agent/broker shall request issuance of the shares and immediately and concurrently sell the shares on the Optionee’s behalf.  Payment of the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option, any brokerage fees, transfer fees, and all applicable taxes due on the Option exercise, shall be deducted from the proceeds of the sale of the shares.  If the person exercising the Option is not the Optionee, such person shall also deliver with the notice of exercise appropriate proof of his or her right to exercise the Option, as the Corporation may require in its sole discretion.  Promptly after exercise of the

4

Option as provided for above, the agent/broker shall deliver to the person exercising the Option the net proceeds from the sale of the shares of Stock being exercised and sold.

                                                                (C)           Sell-to-Cover Exercise (to exercise and immediately sell a portion of the Option Shares):  Subject to the terms and conditions of this Option Agreement and the Plan, the Option may be exercised by delivering written notice of exercise to the agent/broker designated by the Corporation, which notice shall specify the number of shares for which the Option is being exercised and irrevocable instructions to promptly (1) sell the portion (which must be a whole number) of the shares of Stock to be issued upon exercise sufficient to generate proceeds to pay the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option, any brokerage or transfer fees, and all applicable taxes due on the Option exercise (collectively the “Exercise Costs”) and (2) remit to the Corporation a sufficient portion of the sale proceeds to pay the Exercise Price for the shares of Stock purchased pursuant to the exercise of the Option and all applicable taxes due on the Option exercise.  The agent/broker shall request issuance of the shares and immediately and concurrently sell on the Optionee’s behalf only such number of the Shares as is required to generate proceeds sufficient to pay the Exercise Costs.  Promptly after exercise of the Option as provided for above, the Corporation shall deliver to the person exercising the Option a certificate for the shares of Stock issued upon exercise which are not sold to pay the Exercise Costs.  Promptly after exercise of the Option as provided for above, the agent/broker shall deliver to the person exercising the Option any net proceeds from the sale of the Shares in excess of the Exercise Costs.  If the person exercising the Option is not the Optionee, such person shall also deliver with the notice of exercise appropriate proof of his or her right to exercise the Option, as the Corporation may require in its sole discretion.

4.5.2                       As soon as practicable upon the Corporation’s receipt of the Optionee’s notice of exercise and payment, the Corporation shall direct the due issuance of the shares so purchased.

4.5.3                       As a further condition precedent to the exercise of this Option in whole or in part, the Optionee shall comply with all regulations and the requirements of any regulatory authority having control of, or supervision over, the issuance of the shares of Stock and in connection therewith shall execute any documents which the Board shall in its sole discretion deem necessary or advisable.

4.6                                         Forfeiture and Right to Recoupment.

Notwithstanding anything contained herein to the contrary, by accepting this Option, Optionee 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 Optionee, or (b) it is determined that the Optionee has otherwise engaged in misconduct (whether or not such misconduct is discovered by the Corporation prior to the termination of Optionee’s

5

employment), the Board of Directors or a committee thereof (in each case, the “Board”) may take such action with respect to the Option 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 or cancellation of the unvested and/or vested portion of the Option and the recoupment of any proceeds from the exercise or vesting of the Option and/or the sale of Option Shares issued pursuant to this Agreement.  For purposes of this Section 4.6, “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 Optionee at the expense of the Corporation or (ii) have a material adverse effect on the Corporation.  Any determination hereunder, including with respect to Optionee’s misconduct, shall be made by the Board in its sole discretion.  Notwithstanding any provisions herein to the contrary, Optionee expressly acknowledges and agrees that the rights of the Board set forth in this Section 4.6 shall continue after Optionee’s employment with the Corporation 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.

5.                            TRANSFERABILITY OF OPTIONS

During the lifetime of an Optionee, only such Optionee (or, in the event of legal incapacity or incompetency, the Optionee’s guardian or legal representative) may exercise the Option.  No Option shall be assignable or transferable by the Optionee to whom it is granted, other than by will or the laws of descent and distribution.

6.                            COMPLIANCE WITH LAW

The Corporation shall make reasonable efforts to comply with all applicable federal and state securities laws; provided, however, that notwithstanding any other provision of this Option Agreement, the Option shall not be exercisable if the exercise thereof would result in a violation of any such law.

7.                            RIGHTS AS STOCKHOLDER

Neither the Optionee nor any executor, administrator, distributee or legatee of the Optionee’s estate shall be, or have any of the rights or privileges of, a stockholder of the Corporation in respect of any shares of Stock issuable hereunder unless and until such shares have been fully paid and certificates representing such shares have been endorsed, transferred and delivered, and the name of the Optionee (or of such personal representative, administrator, distributee or legatee of the Optionee’s estate) has been entered as the stockholder of record on the books of the Corporation.

8.                            WITHHOLDING OF TAXES

If the Corporation shall be required to withhold any federal, state, local or foreign tax in connection with exercise of this Option, it shall be a condition to such exercise that the Optionee pay or make provision satisfactory to the Corporation for payment of all such taxes.  The Optionee may elect that all or any part of such withholding requirement be satisfied by retention by the Corporation of a portion of the shares purchased upon exercise of this Option.  If such election is made, the shares

6

so retained shall be credited against such withholding requirement at the fair market value on the date of exercise.

9.                            DISCLAIMER OF RIGHTS

No provision in this Option Agreement shall be construed to confer upon the Optionee the right to be employed by the Corporation or any Subsidiary, or to interfere in any way with the right and authority of the Corporation or any Subsidiary either to increase or decrease the compensation of the Optionee at any time, or to terminate any employment or other relationship between the Optionee and the Corporation or any Subsidiary.

(a)          Any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (a “Person”) becomes the beneficial owner (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either (i) the then-outstanding shares of common stock of the Corporation (the “Outstanding Corporation Common Stock”) or (ii) the combined voting power of the then-outstanding voting securities of the Corporation entitled to vote generally in the election of directors (the “Outstanding Corporation Voting Securities”); provided, however, that, for purposes of this Section 1(d), the following acquisitions shall not constitute a Change in Control:  (A) any acquisition directly from the Corporation, (B) any acquisition by the Corporation, (C) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Corporation or any company controlled by, controlling or under common control with the Corporation or (iv) any acquisition by any corporation pursuant to a transaction that complies with Sections 10(c)(A), 10(c)(B) and 10(c)(C);

(d)         Approval by the stockholders of the Corporation of a complete liquidation or dissolution of the Corporation.]

11.                               COMPLIANCE WITH SECTION 409A OF THE CODE.

To the extent applicable, it is intended that this Option Agreement and the Plan comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) do not apply to Optionee.  This Option Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause the Option Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Corporation without the consent of the Optionee).

12.                               INTERPRETATION OF THIS OPTION AGREEMENT

All decisions and interpretations made by the Board or the Compensation Committee thereof with regard to any question arising under the Plan or this Option Agreement shall be binding and conclusive on the Corporation and the Optionee and any other person entitled to exercise the Option as provided for herein.

This Option Agreement and the Plan together constitute the entire agreement and supersedes all prior understandings and agreements, written or oral, of the parties hereto with respect to the subject matter hereof.  Except for amendments to the Plan incorporated into this Option Agreement by reference pursuant to Section 2 above, neither this Option Agreement nor any term hereof may be amended, waived, discharged or terminated except by a written instrument signed by the Corporation and the Optionee; provided, however, that the Corporation unilaterally may waive any provision hereof in writing to the extent that such waiver does not adversely affect the interests of the Optionee hereunder, but no such waiver shall operate as or be construed to be a subsequent waiver of the same provision or a waiver of any other provision hereof.  In the event that it is determined that the Optionee was not eligible to receive this Option, the Option and this Option Agreement shall be null and void and of no further effect.
