Exhibit 10.2

CHANGE IN CONTROL EMPLOYMENT AGREEMENT

AGREEMENT, dated as of the [         ] day of [                   ] (this “Agreement”), by and between Transaction Systems Architects, Inc., a Delaware corporation (the “Company”), and [                   ] (the “Executive”).

WHEREAS, the Board of Directors of the Company (the “Board”), has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat or occurrence of a Change in Control (as defined herein).  The Board believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change in Control and to encourage the Executive’s full attention and dedication to the Company in the event of any threatened or pending Change in Control, and to provide the Executive with compensation and benefits arrangements upon a Change in Control that ensure that the compensation and benefits expectations of the Executive will be satisfied and that provide the Executive with compensation and benefits arrangements that are competitive with those of other corporations.  Therefore, in order to accomplish these objectives, the Board has caused the Company to enter into this Agreement.

(2)            During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote reasonable attention and time during normal business hours to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive hereunder, to use the Executive’s reasonable best efforts to perform faithfully and efficiently such responsibilities.  During the Employment Period, it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable boards or committees, (B) deliver lectures, fulfill speaking engagements or teach at educational institutions and (C) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive’s responsibilities as an employee of the Company in accordance with this Agreement.  It is expressly understood and agreed that, to the extent that any such activities have been conducted by the Executive prior to the Effective Date, the continued conduct of such activities (or the conduct of activities similar in nature and scope thereto) subsequent to the Effective Date shall not thereafter be deemed to interfere with the performance of the Executive’s responsibilities to the Company.

(3)            Incentive, Savings and Retirement Plans .  During the Employment Period, the Executive shall be entitled to participate in all cash incentive, equity incentive, savings and retirement plans, practices, policies, and programs applicable generally to other peer executives of the Company and the Affiliated Companies, but in no event shall such plans, practices, policies and programs provide the Executive with incentive opportunities (measured with respect to both regular and special incentive opportunities, to the extent, if any, that such distinction is applicable), savings opportunities and retirement benefit opportunities, in each case, less favorable, in the aggregate, than the most favorable of those provided by the Company and the Affiliated Companies for the Executive under such plans, practices, policies and programs as in effect at any time during the 120-day period immediately preceding the Effective Date or, if more favorable to the Executive, those provided generally at any time after the Effective Date to other peer executives of the Company and the Affiliated Companies.

(7)            Vacation .  During the Employment Period, the Executive shall be entitled to paid vacation in accordance with the most favorable plans, policies, programs and practices of the Company and the Affiliated Companies as in effect for the Executive at any time during the 120-day period immediately preceding the Effective Date or, if more favorable to the Executive, as in effect generally at any time thereafter with respect to other peer executives of the Company and the Affiliated Companies.

Section 4.               Termination of Employment .   (a)  Death or Disability .   The Executive’s employment shall terminate automatically if the Executive dies during the Employment Period.  If the Company determines in good faith that the Disability (as defined herein) of the Executive has occurred during the Employment Period (pursuant to the definition of “Disability”), it may give to the Executive written notice in accordance with Section 11(b) of its intention to terminate the Executive’s employment.  In such event, the Executive’s employment with the Company shall terminate effective on the 30th day after receipt of such notice by the Executive (the “Disability Effective Date”), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive’s duties.  “Disability” means the absence of the Executive from the Executive’s duties with the Company on a full-time basis for 180 consecutive business days as a result of incapacity due to mental or physical illness that is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive’s legal representative.

(b)            Cause .  The Company may terminate the Executive’s employment during the Employment Period with or without Cause.  “Cause” means:

(1)            the Executive’s conviction of, or entry of a plea of guilty or no contest to, a felony or any lesser crime of which fraud or dishonesty is an element,

(2)            the Executive’s willful misconduct or willful omission of duties (other than any such misconduct or omission resulting from the Executive’s incapacity due to physical or mental illness or following the Executive’s delivery of a Notice of Termination for Good Reason) that is or could reasonably be expected to be injurious to the Company other than in an immaterial manner, or

(3)            the Executive’s violation of any provision of (A) the Company’s Code of Business Conduct and Ethics, as the same may be amended from time to time, or (B) the Company’s Code of Ethics for the Chief Executive Officer and Senior Financial Officers, as the same may be amended from time to time (the “Code of Ethics”) that is, in each case, materially and demonstrably injurious to the Company.  For purposes of the foregoing sentence, the Executive shall be deemed to be subject to the provisions of the Code of Ethics regardless of whether the Executive is a Senior Officer as defined in the Code of Ethics or otherwise subject to the Code of Ethics.

For purposes of this Section 4(b), no act, or failure to act, on the part of the Executive shall be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company.  Any act, or failure to act, based upon authority (A) given pursuant to a resolution duly adopted by the Board, or if the Company is not the ultimate parent corporation of the Affiliated Companies and is not publicly-traded, the board of directors of the ultimate parent of the Company (the “Applicable Board”), (B) upon the instructions of the Chief Executive Officer of the Company , or (C) based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Company.  The cessation of employment of the Executive shall not be deemed to be for Cause unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Applicable Board (excluding the Executive, if the Executive is a member of the Applicable Board) at a meeting of the Applicable Board called and held for such purpose (after reasonable notice is provided to the Executive and the Executive is given an opportunity, together with counsel for the Executive, to be heard before the Applicable Board), finding that, in the good faith opinion of the board, the Executive is guilty of the conduct described in Section 4(b)(1), 4(b)(2) or 4(b)(3), and specifying the particulars thereof in detail.

(c)            Good Reason .  The Executive’s employment may be terminated by the Executive for Good Reason or by the Executive voluntarily without Good Reason.  “Good Reason” means:

(1)            the assignment to the Executive of any duties inconsistent in any respect with the Executive’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by Section 3(a), or any other diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and that is remedied by the Company promptly after receipt of notice thereof given by the Executive;

(2)            any failure by the Company to comply with any of the provisions of Section 3(b), other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and that is remedied by the Company promptly after receipt of notice thereof given by the Executive;

(3)            the Company’s requiring the Executive (i) to be based at any office or location other than as provided in Section 3(a)(1)(B), (ii) to be based at a location other than the principal executive offices of the Company if the Executive was employed at

such location immediately preceding the Effective Date, or (iii) to travel on Company business to a substantially greater extent than required immediately prior to the Effective Date;

(4)            any purported termination by the Company of the Executive’s employment otherwise than as expressly permitted by this Agreement; or

(5)            any failure by the Company to comply with and satisfy Section 10(c).

The Executive’s mental or physical incapacity following the occurrence of an event described above in clauses (1) through (5) shall not affect the Executive’s ability to terminate employment for Good Reason.  A termination by the Executive with Good Reason shall be effective only if, within 180 days of the Executive’s first becoming aware of the circumstances giving rise to Good Reason, the Executive delivers a Notice of Termination for Good Reason by Executive to the Company, and, to the extent such circumstances are curable, the Company within 30 days following its receipt of such notification has failed to cure the circumstances giving rise to Good Reason.

(d)            Notice of Termination .  Any termination by the Company for Cause, or by the Executive for Good Reason, shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 11(b).  “Notice of Termination” means a written notice that (1) indicates the specific termination provision in this Agreement relied upon, (2) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated, and (3) if the Date of Termination (as defined herein) is other than the date of receipt of such notice, specifies the Date of Termination (which Date of Termination shall be not more than 30 days after the giving of such notice).  The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance that contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company, respectively, hereunder or preclude the Executive or the Company, respectively, from asserting such fact or circumstance in enforcing the Executive’s or the Company’s respective rights hereunder.

(e)            Date of Termination . “Date of Termination” means (1) if the Executive’s employment is terminated by the Company for Cause, or by the Executive for Good Reason, the date of receipt of the Notice of Termination or any later date specified in the Notice of Termination, (which date shall not be more than 30 days after the giving of such notice), as the case may be, (2) if the Executive’s employment is terminated by the Company other than for Cause or Disability, the date on which the Company notifies the Executive of such termination, (3)
