                                   Addendum
                                      to
                           SunGard Data Systems Inc.
                          1996 Equity Incentive Plan

                            Rules for UK employees

In pursuance of its powers under the 1996 Equity Incentive Plan ("the Plan") 
the Compensation Committee ("the Committee") of the Board of Directors of 
SunGard Data Systems Inc. ("the Company") had adopted these rules for the 
purposes of operating the Plan with regard to such options to which these rules 
are expressed to extend at the time when the option is granted. Unless the 
context requires otherwise, all expressions used in the rules have the same 
meaning as in the Plan. The Plan, as supplemented by these rules, is referred to
hereinafter as "this Sub-Plan". For the avoidance of doubt, the terms of the 
Plan (insofar as they have not been disapplied by Rule 13 or these rules) shall 
form part of the Sub-Plan.

1.  The Common Shares over which options may be granted under the Sub-Plan form
    part of the ordinary share capital (as defined in section 832(1) Income and
    Corporation Taxes Act 1988) ("ICTA 1988") of the Company and must at all
    times, (including the time of grant and the time of exercise) comply with
    the terms of the Plan and comply with the requirements of paragraphs 10 to
    14 Schedule 9 ICTA 1988.

2.  The companies participating in this Sub-Plan are the Company and all
    companies controlled by the Company within the meaning of section 840 ICTA
    1988 ("Subsidiaries") and which have been nominated by the Committee to
    participate for the time being in this Sub-Plan.

3.  The Common Shares are reported by NASDAQ.

4.  The Common Shares to be acquired on exercise of the option in accordance 
    with the terms of the Plan will:

    a)  be fully paid up;

    b)  be not redeemable;

    c)  not be subject to any restrictions other than restrictions which attach
        to all shares of stock of the same class. For the purpose of this
        clause, the term restrictions includes restrictions which are deemed to
        attach to the shares under any contract, agreement, arrangement of
        condition as referred to in paragraph 13 Schedule 9 ICTA 1988. Provided
        that such restrictions:

        i)  be objective, specified at the date of grant and set out in full in,
            or details given with, the Award; and

        ii) be such that rights to exercise such Option after the fulfillment or
            attainment of any conditions and limitations so specified shall not
            be dependent upon the further discretion of any person; and

<PAGE>
 
                (iii)   not be capable of amendment, variation or waiver unless
                        an event occurs which causes the Committee to consider
                        that a waived, varied or amended condition would be a
                        fairer measure of performance and would be no more
                        difficult to satisfy.

5.      The Company has only one class of Common shares.

6.      No option will be granted to any employee or director under this Sub-
        Plan, or where an option has previously been granted no option shall be
        exercised by an option-holder if at that time he has, or any time within
        the preceding 12 months has had, a material interest for the purposes of
        Schedule 9 ICTA 1988 in either the Company being a close company (within
        the meaning of Chapter I of Part XI of ICTA 1988) or in a company being
        a close company which has control (with the meaning of section 840 ICTA
        1988) of the Company or in a company being a close company and a member
        of a consortium (as defined in section 187(7) ICTA 1988) which owns the
        Company. In determining whether a company is a close company for this
        purpose section 414(1)(a) ICTA 1988 (exclusion of companies not resident
        in the United Kingdom) and section 415 ICTA 1988 (exclusion of certain
        companies with listed shares) shall be disregarded.

7.      No option will be granted to an employee or director under this Sub-Plan
        in relation to which exercise price is manifestly less than the fair
        market value (as defined in Section 187(2) ICTA 1988) of the Company's
        Common Shares on the date of grant of the option and the exercise price
        shall be stated at the date of grant of the option and determined in
        accordance with Section 11.9 of the Plan (provided that this method of
        determination is acceptable to the Shares Valuation Division of the
        Inland Revenue) or otherwise determined in advance with the agreement of
        the Shares Valuation Division.

8.      (a)     Any alteration of amendment of this Sub-Plan shall not have
                effect unless approved by the Board of Inland Revenue. The
                Company undertakes to provide details thereof to the Board of
                Inland Revenue without delay for this purpose.

        (b)     For the purposes of this Sub-Plan no adjustment pursuant to any
                of the provisions of the Plan shall be made to any option which
                has been granted under the Sub-Plan unless such adjustment would
                be permitted under the Plan and under Paragraph 29 Schedule 9
                ICTA 1988 and where so permitted no such adjustment shall take
                effect unless the approval of the Board of Inland Revenue shall
                have been obtained thereto.

9.      For the avoidance of doubt it is stated that the Company is the grantor 
        as defined in paragraph 1(1) Schedule 9 ICTA 1988.

10.     Any option granted to an employee or director under this Sub-Plan shall
        be limited to take effect so that immediately following such grant the
        aggregate market value of shares (determined at the time prescribed by
        paragraph 28 Schedule 9 ICTA 1988 and calculated in accordance with the
        provisions of the said Schedule 9) wich he can acquire under this Sub-
        Plan and any other scheme or schemes, not being a savings-related share
        option scheme, approved under this said Schedule 9 and established by
        the grantor or by any associated company (as defined in section 416 ICTA
        1988) of the grantor (and not exercised) shall not exceed (Pounds)30,000
        or such other limit as may be prescribed from time to time provided
        always that the extent that any grant of
<PAGE>
 
     any option exceeds the limit prescribed in this Rule 10, it shall be deemed
     to comprise such number of shares as may when aggregated with any other
     shares remaining issuable or transferable as provided in this Rule 10 in
     respect of options granted to that employee or director be equal to, but
     not exceed, such limit, provided always that this limit shall not exceed
     the limitations set out in the Plan.

11.  An option will be granted under this Sub-Plan to an employee (other than
     one who is a director) or a full-time director of the Company or a company
     participating in this Sub-Plan. For this purpose, a full-time director is
     one who is required to work at least 25 hours a week excluding meal-times
     in the business of the Company or its subsidiaries.

12.  The Company shall not later than 30 days upon actual receipt of the written
     notice of exercise of an option given in accordance with the provisions of
     the Plan together with the payment of the aggregate exercise price in
     respect of Common Shares to be issued pursuant to the exercise of an
     option, allot and issue credited as fully paid to the Optionee and cause to
     be registered in his name the number of Common Shares specified in the
     written notice.

13.  For the purposes of the Sub-Plan, the following parts of the Plan shall be 
     disregarded:

     (a)     the second sentence of Section 5.1 (d);
     (b)     all words after "of SunGard" in line three of Section 5.1(e);
     (c)     Section 5.1(f);
     (d)     Section 5.2; 
     (e)     Section 5.3;
     (f)     Section 5.4;
     (g)     Section 6.1(b) and (c);
     (h)     Section 6.2(b), (c), (d) and (e);
     (i)     Section 6.3(a)(2) and (3);
     (j)     the last two sentences of Section 7.3; and 
     (k)     Section 11.8


The undersigned certifies that this addendum was duly adopted by the 
Compensation Committee of the Board of Directors of SunGard Data Systems Inc.
on the 14th day of February 1997.
