On March 19, 1998, SunGard Data Systems Inc., a Delaware corporation
("SunGard"), filed Registration Statement No. 33-48259 on Form S-3, which was
later amended on April 8, 1998 (the "Registration Statement") to register
632,935 shares (the "Shares") of common stock, $.01 par value per share, of
SunGard (the "Common Stock") owned by the selling stockholders listed on Page 5
of the Prospectus (the "Selling Stockholders"). The Prospectus informed the
Selling Stockholders that they would be permitted to sell the Shares while the
Registration Statement was in effect.
On March 27, 1998, the Registration Statement became effective. Since the
effective date, certain Selling Stockholders have sold Shares; however, some
Selling Stockholders did not sell all of their Shares.
Accordingly, SunGard hereby deregisters a total of 26,500 shares of Common
Stock, comprised of the Shares not sold by the Selling Stockholders during the
effective period.
