$550,000.00                                                      Omaha, Nebraska
                                                                     May 1, 2001

     FOR VALUE RECEIVED, the undersigned, William E. Fisher ("Fisher"), hereby
promises to pay to the order of Transaction Systems Architects, Inc., a Delaware
corporation (together with its successors and assigns the "Holder"), the
principal sum of Five Hundred Fifty Thousand Dollars ($550,000.00), together
with interest from the date hereof at the rate of eight percent (8.00%) per
annum on the unpaid principal balance hereof, with the entire amount of
indebtedness hereunder then outstanding, including principal and accrued
interest, due on June 1, 2002. Interest shall be computed on the basis of a
360-day year.

     If this Promissory Note becomes due and payable on a Saturday, Sunday or
business holiday in the State of Nebraska, payment shall be made on the next
successive business day with the same effect as though made on the due date.

     Fisher reserves the right to prepay all or any portion of this Promissory
Note at any time and from time to time without premium or penalty of any kind.

     If (i) there should be a default in the payment of interest or principal
due hereunder, or (ii) Fisher should make an assignment for the benefit of
creditors, or (iii) attachment or garnishment proceedings are commenced against
Fisher, or (iv) a receiver, trustee or liquidator is appointed over or execution
levied upon any property of Fisher, or (v) proceedings are instituted by or
against Fisher, under any bankruptcy, insolvency, reorganization or other law
relating to the relief of debtors, including without limitation the United
States Bankruptcy Code, as amended, or (vi) Fisher breaches any of his
warranties or obligations under that certain Agreement and Release of All Claims
entered into by and between Fisher and Holder concurrently with this Promissory
Note, then, and in each such event, the Holder may, at its option, without
notice or demand (except as otherwise provided in and subject to the terms of
the Agreement and Release of All Claims), declare the remaining unpaid principal
balance of this Promissory Note and all accrued interest thereon immediately due
and payable in full.

     Any amount hereunder which is not paid when due, whether at stated
maturity, by acceleration or otherwise, shall bear interest from the date when
due until paid at the lesser of (1) twelve percent (12%) per annum, or (2) the
maximum rate permitted by law, said interest to be compounded annually and
computed on the basis of a 360-day year.

     Payments made hereunder shall be made in lawful currency of the United
States of America to the attention of Holder at 244 S. 108th Street, Omaha,
Nebraska 68154-2684 or at such other place as the Holder may designate in
writing. All payments made hereunder, whether at stated maturity, prepayment, or
payment as a result of acceleration, shall be allocated first to accrued but
unpaid interest and then to principal remaining outstanding hereunder.

     Fisher agrees to pay all reasonable costs of collection, including
attorneys' fees to the extent allowed by law, paid or incurred by the Holder in
enforcing this Promissory Note on default or the rights and remedies herein
provided.

<Page>

     Fisher hereby waives demand of payment, presentment for payment, protest,
notice of nonpayment or dishonor and any and all other notices and demands
whatsoever, and any and all delays or lack of diligence in the collection
hereof, and expressly consents and agrees to any and all extensions or
postponements of the time of payment hereof from time to time at or after
maturity and any other indulgence and waives all notice thereof.

     No delay or failure by the Holder in exercising any right, power, privilege
or remedy hereunder shall affect such right, power, privilege or remedy or be
deemed to be a waiver of the same or any part thereof; nor shall any single or
partial exercise thereof or any failure to exercise the same in any instance
preclude any further or future exercise thereof, or exercise of any other right,
power, privilege or remedy, and the rights and privileges provided for hereunder
are cumulative and not exclusive.

     The Holder may sell, assign, pledge or otherwise transfer all or any
portion of its interest in this Promissory Note at any time or from time to time
without prior notice to or consent of and without releasing any party liable or
becoming liable hereon.

     By executing this Promissory Note, Fisher hereby acknowledges that this
Promissory Note constitutes his legal and binding obligation and is enforceable
against him in accordance with its terms.

     This Promissory Note shall be governed by and construed and enforced in
accordance with the laws of the State of Nebraska.

     IN WITNESS WHEREOF, the undersigned has duly caused this Promissory Note to
be executed and delivered at the place specified above and as of the date first
written above.
