    THIS INCENTIVE STOCK OPTION AGREEMENT, made and entered into this 1st day 
of March, 1996, by and between PAYSYS INTERNATIONAL, INC., a Florida 
corporation (the "Corporation") and David Black (the "Optionee"),
     
                             W I T N E S S E T H:
                             -------------------
                                             
    WHEREAS, the Board of Directors of the Corporation (the "Board") has 
adopted the PaySys International, Inc. 1995 Stock Incentive Plan (the "Plan");

    WHEREAS, the Plan provides for the granting of incentive stock options by 
the Board to directors, officers and key employees of the Corporation or any 
subsidiary of the Corporation to purchase shares of the Common Stock of the 
Corporation, par value $.01 per share (the "Stock") in accordance with the 
terms and provisions thereof; and

    WHEREAS, the Board considers the Optionee to be a person who is eligible 
for a grant of incentive stock options under the Plan, and has determined 
that it would be in the best interest of the Corporation to grant the 
incentive stock options documented herein;

    NOW, THEREFORE, the parties hereto, intending to be legally bound hereby, 
agree as follows:

    1.   Grant of Option.
         ---------------

    Subject to the terms and conditions hereinafter set forth, the 
Corporation hereby grants to the Optionee, as of the date hereof (the "Date 
of Grant"), an option to purchase up to 16,194 shares of Stock at a price of 
$4.00 per share, the fair market value as of the date hereof.  Such option is 
hereinafter referred to as the "'Option" and the shares of stock purchasable 
upon exercise of the Option are hereinafter sometimes referred to as the 
"Option Shares."  The Option is intended by the parties hereto to be, and 
shall be treated as, an incentive stock option, as such term is defined under 
section 422 of the Internal Revenue Code of 1986 (the "Code").

    2.   Installment Exercise.
         --------------------

    Subject to such further limitations as are provided herein, the Option 
shall become vested as follow:  
100% of the options become exercisable on the earlier to occur of February 
28, 2003 or the Milestone Date, but in no event shall any options become 
exercisable before January 1, 1998.  For purposes of this agreement, the 
Milestone Date is the date on which the Corporation has sold and installed a 
minimum of two (2) software licenses in each of two (2) consecutive years, 
such licenses relating to software based on the technology which is the of 
the 



Assignment and Transfer of Patent Rights and Other Intellectual Property 
Rights dated March 1, 1996 between Optionee and the Corporation.

Notwithstanding anything to the contrary in the above paragraph, in the event 
that the Corporation sells substantially all of its asset, or more than fifty 
percent of the voting stock of the Corporation is acquired by any person or 
entity not currently a shareholder, or the Corporation completes an initial 
public offering prior to January 1, 1998, the Option shall vest in its 
entirety and become completely exercisable immediately prior to the event.

    3.   Termination of Option.
         ---------------------

    (a)  The Option and all rights hereunder with respect thereto, to the 
extent such rights shall not have been exercised, shall terminate and become 
null and void after the expiration of ten years from the Date of Grant (the 
"Option Term").

    (b)  In the event of termination of Optionee's employment after the date 
or dates for exercise of the Option, other than termination that is (a) for 
cause, (b) voluntary on the part of the Optionee and without the written 
consent of the Corporation or (c) due to death or disability or to retirement 
in accordance with normal retirement policies as in effect from time to time, 
the Optionee may exercise the Option at any time within a period ending at 
the earlier of the Expiration Date or 5:00 P.M. eastern time, on the day 
preceding the expiration of three months from the date of termination of 
employment, to the extent of the number of shares which were purchasable 
hereunder at the date of termination. As to the shares which were not 
purchasable on such date, the Option shall terminate on such date of 
termination of employment and shall not thereafter be or become exercisable.

    Upon a termination of the Optionee's employment by reason of retirement, 
disability, or death, the Option may be exercised during the following 
periods, but only to the extent that the Option was outstanding and 
exercisable on any such date of retirement, disability or death: (i) the 
one-year period following the date of such termination of the Optionee's 
employment in the case of a disability (within the meaning of Section 
22(e)(3) of the Code), (ii) the six-month period following the date of 
issuance of letters testamentary or letters of administration to the executor 
or administrator of a deceased Optionee, in the case of the Optionee's death 
during his employment by the Employer, but not later than one year after the 
Optionee's death, and (iii) the three-month period following the date of such 
termination in the case of retirement on or after attainment of age 65, or in 
the case of disability other than as described in (i) above.  In no event, 
however, shall any such period extend beyond the Option Term.

    (c)  In the event of the death of the Optionee, the Option may be 
exercised by the Optionee's legal representative(s), but only to the extent 
that the Option would otherwise have been exercisable by the Optionee at the 
time of his death.

                                      2



    (d)  A transfer of the Optionee's employment between the Corporation and 
any subsidiary of the Corporation, or between any subsidiaries of the 
Corporation, shall not be deemed to be a termination of the Optionee's 
employment.

    (e)  Notwithstanding any other provisions set forth herein or in the 
Plan, if the Optionee shall (i) voluntarily terminate employment without the 
Corporation's consent, (ii) commit any act of malfeasance or wrongdoing 
affecting the Corporation or any subsidiary of the Corporation, (iii) breach 
any covenant not to compete, or employment contract, with the Corporation or 
any subsidiary of the Corporation, or (iv) engage in conduct that would 
warrant the Optionee's discharge for cause (excluding general dissatisfaction 
with the performance of the Optionee's duties, but including any act of 
disloyalty or any conduct clearly tending to bring discredit upon the 
Corporation or any subsidiary of the Corporation), any unexercised portion of 
the Option shall immediately terminate and be void.
 
    4.   Exercise of Options.
         -------------------

    (a)  The Optionee may exercise the Option with respect to all or any part 
of the number of Option Shares then exercisable hereunder by giving the 
Secretary of the Corporation written notice of intent to exercise.  The 
notice of exercise shall specify the number of Option Shares as to which the 
Option is to be exercised and the date of exercise thereof, which date shall 
be at least five days after the giving of such notice unless an earlier time 
shall have been mutually agreed upon.

    (b)  Full payment (in U.S. dollars) by the Optionee of the option price 
for the Option Shares purchased shall be made on or before the exercise date 
specified in the notice of exercise in cash, or, with the prior written 
consent of the Board, in whole or in part through the surrender of previously 
acquired shares of Stock at their fair market value on the exercise date.

    On the exercise date specified in the Optionee's notice or as soon 
thereafter as is practicable, the Corporation shall cause to be delivered to 
the Optionee, a certificate or certificates for the Option Shares then being 
purchased (out of theretofore unissued Stock or required Stock, as the 
Corporation may elect) upon full payment for such Option Shares.  The 
obligation of the Corporation to deliver Stock shall, however, be subject to 
the condition that if at any time the Board shall determine in its discretion 
that the listing, registration or qualification of the Option Shares upon any 
securities exchange or under any state or federal law, or the consent or 
approval of any governmental regulatory body, is necessary or desirable as a 
condition of, or in connection with, the Option or the issuance or purchase 
of Stock thereunder, the Option may not be exercised in whole or in part 
unless such listing, registration, qualification, consent, or approval shall 
have been effected or obtained free of any conditions not acceptable to the 
Board.

                                      3



    (c)  If the Optionee fails to pay for any of the Option Shares specified 
in such notice or fails to accept delivery thereof, the Optionee's right to 
purchase such Option Shares may be terminated by the Corporation.  The date 
specified in the Optionee's notice as the date of exercise shall be deemed 
the date of exercise of the Option, provided that payment in full for the 
Option Shares to be purchased upon such exercise shall have been received by 
such date.

    5.   Adjustment of and Changes in Stock of the Corporation.
         -----------------------------------------------------

    In the event of a reorganization, recapitalization, change of shares, 
stock split, spin-off, stock dividend, reclassification, subdivision, or 
combination of shares, merger, consolidation, rights offering, or any other 
change in the corporate structure or shares of capital stock of the 
Corporation, the Board shall make a proportional adjustment in the number and 
kind of shares of Stock subject to the Option or in the option price; 
provided, however, that no such adjustment shall give the Optionee any 
additional benefits under the Option.

    In the event that, within five years from the date of grant, the Company 
sells shares of its common stock at a price per share which is less than the 
option price per share, then the number of shares subject to this option 
shall be increased such that the ratio of the Option Shares to the total 
shares outstanding after the sale is the same as such ratio would have been 
had the number of shares issued in such transaction been equal to the total 
consideration paid divided by the option price.  The option price per share 
shall be decreased so that the total purchase price for the Option Shares (as 
increased) is the same as before the sale.
    
    6.   No Rights of Stockholders.
         -------------------------

    Neither the Optionee nor any personal representative shall be, or shall 
have any of the rights and privileges of, a stockholder of the Corporation 
with respect to any shares of Stock purchasable or issuable upon the exercise 
of the Option, in whole or in part, prior to the date of exercise of the 
Option.

    7.   Non-Transferability of Option.
         -----------------------------

    During the Optionee's lifetime, the Option hereunder shall be exercisable 
only by the Optionee or any guardian or legal representative of the Optionee, 
and the Option shall not be transferable except, in case of the death of the 
Optionee, by will or the laws of descent and distribution, nor shall the 
Option be subject to attachment, execution or other similar process.  In no 
event of (a) any attempt by the Optionee to alienate, assign, pledge, 
hypothecate or otherwise dispose of the option, except as provided for 
herein, or (b) the levy of any attachment, execution or similar process upon 
the rights or interest hereby conferred, the Corporation may terminate the 
Option by notice to the Optionee and it shall thereupon become null and void.


                                      4



    8.   Registration of Option Shares.
         -----------------------------

    The Corporation will file a registration on Form S-8 (or any successor 
form) covering the Option Shares prior to the exercise of the Option, 
provided that the Option Shares are eligible for registration on such form.

    9.   Employment Not Affected.
         -----------------------

    Neither the granting of the Option nor its exercise shall be construed as 
granting to the Optionee any right with respect to continuance of employment 
by the Corporation or any parent or subsidiary.  Except as may otherwise be 
limited by a written agreement between the Corporation or a parent or 
subsidiary thereof and the Optionee, the right of the Optionee's employer to 
terminate at will the Optionee's employment with it at any time (whether by 
dismissal, discharge, retirement or otherwise) is specifically reserved by 
the Corporation, as the employer or on behalf of the employer (whichever the 
case may be), and acknowledged by the Optionee.

    10.  Amendment of Option.
         -------------------

    The Option may be amended by the Board at any time (i) if the Board 
determines, in its sole discretion, that amendment is necessary or advisable 
in the light of any addition to or change in the Code or in the regulations 
issued thereunder, or any federal or state securities law or other law or 
regulation, which change occurs after the Date of Grant and by its terms 
applies to the Option; or (ii) other than in the circumstances described in 
clause (i), with the consent of the Optionee.

    11.  Notice.
         ------

    Any notice to the Corporation provided for in this instrument shall be 
addressed to it in care of its Secretary at its executive offices at The 
Spectrum Building, 900 Winderley Place, P.O. Box 5575, Maitland, Florida 
32751-5575, and any notice to the Optionee shall be addressed to the Optionee 
at the current address shown on the payroll records of the Corporation or any 
parent or subsidiary employing Optionee.  Any notice shall be deemed to be 
duly given if and when properly addressed and posted by registered or 
certified mail, postage prepaid.

                                      5



    12.  Incorporation of Plan by Reference.
         ----------------------------------

    The Option is granted pursuant to the terms of the Plan, the terms of 
which are incorporated herein by reference, and the Option shall be in all 
respects interpreted in accordance with the Plan.   The Board shall interpret 
and construe the Plan and this instrument, and its interpretations and 
determinations shall be conclusive and binding on the parties hereto and any 
other person claiming an interest hereunder, with respect to any issue 
arising hereunder or thereunder.

    13.  Governing Law.
         -------------
