AMENDMENT TO THE

NATIONAL DATA CORPORATION 1987 STOCK OPTION PLAN

December 19, 2000

Section 6(a) of the Plan is hereby deleted in its entirety and the following is substituted therefor:

6(a) Change in Capital Structure. In the event that the Committee shall determine that any dividend or other distribution (whether in the form of cash, Common Stock, or other property), recapitalization, stock split, reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase, share exchange or other similar corporate transaction or event, affects the Common Stock such that an adjustment is appropriate in order to prevent dilution or enlargement of the rights of an Optionee under the Plan, then the Committee shall make such equitable changes or adjustments as it deems necessary or appropriate to any or all of (i) the number and kind of stock or other securities that may thereafter be issued in connection with the Plan, including without limitation the maximum number of Options that may be granted to any one participant during a particular time period, (ii) the number and kind of stock or other securities issuable in respect of outstanding Options, and (iii) the exercise price or purchase price relating to any Option; provided that, with respect to Incentive Stock Options, such adjustment shall be made in accordance with Section 424(c) of the Code, to the extent applicable. Any such adjustments made by the Committee shall be conclusive.

The undersigned certifies this to be a correct copy of the Amendment to the Plan as adopted by the Board of Directors of the Company on December 19, 2000.
