                        MOUNTAIN VIEW, CALIFORNIA 94043
 
Dear Stockholder:
 
  As you may be aware, Infinity Financial Technology, Inc. ("Infinity") has
entered into an Agreement and Plan of Merger and Reorganization (the
"Reorganization Agreement") with SunGard Data Systems Inc., a Delaware
corporation ("SunGard"), providing for the acquisition of Infinity by SunGard.
Pursuant to the Reorganization Agreement, a special meeting of stockholders of
Infinity (the "Infinity Special Meeting") will be held at the principal
executive offices of Infinity located at 640 Clyde Court, Mountain View,
California 94043 on       , 1997 at    a.m., local time.
 
  At the Infinity Special Meeting you will be asked to consider and vote upon
a proposal to adopt and approve the Reorganization Agreement which provides
for the merger of a wholly owned subsidiary of SunGard with and into Infinity
(the "Merger"). Upon consummation of the Merger, Infinity will become a wholly
owned subsidiary of SunGard. As a result of the Merger, each outstanding share
of common stock of Infinity will be converted into the right to receive 0.68
of a share of common stock of SunGard (subject to adjustment as appropriate to
reflect any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction involving the
common stock of SunGard or the common stock of Infinity between the date of
the Reorganization Agreement and the effective time of the Merger). In
addition, SunGard will assume Infinity's obligations with respect to
outstanding options and rights to purchase Infinity stock. The Merger is
described more fully in the accompanying Proxy Statement/Prospectus.
 
  After careful consideration, the Infinity Board of Directors has unanimously
approved the Reorganization Agreement and the Merger, and has concluded they
are fair to, and in the best interests of, Infinity and its stockholders. Your
Board of Directors unanimously recommends a vote in favor of the adoption and
approval of the Reorganization Agreement and the approval of the Merger.
 
  In the materials accompanying this letter you will find a Notice of Special
Meeting of Stockholders, a Proxy Statement/Prospectus relating to the proposal
to be voted upon at the Infinity Special Meeting and a Proxy Card. The Proxy
Statement/Prospectus more fully describes the proposed transaction.
Stockholders are urged to review carefully the information contained in the
accompanying Proxy Statement/Prospectus, including the information under the
captions "Risk Factors," "Infinity Special Meeting--Board Recommendation,"
"Approval of the Merger and Related Transactions--Infinity's Reasons For the
Merger," "--Background of the Merger" and "--Interests of Certain Persons in
the Merger" prior to voting on the proposal.
 
  All stockholders are cordially invited to attend the Infinity Special
Meeting in person. If you attend the Infinity Special Meeting, you may vote in
person if you wish even though you have previously returned your completed
proxy. WHETHER OR NOT YOU PLAN TO ATTEND THE INFINITY SPECIAL MEETING, IT IS
IMPORTANT THAT YOUR SHARES BE REPRESENTED AND VOTED AT THE INFINITY SPECIAL
MEETING, REGARDLESS OF THE NUMBER OF SHARES YOU HOLD. APPROVAL OF THE MERGER
REQUIRES THE AFFIRMATIVE VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING
SHARES OF INFINITY COMMON STOCK. THEREFORE, PLEASE COMPLETE, SIGN, DATE AND
RETURN YOUR PROXY IN THE ENCLOSED ENVELOPE. PLEASE DO NOT SEND IN THE STOCK
CERTIFICATE(S) REPRESENTING YOUR INFINITY COMMON STOCK AT THIS TIME.
 
  On behalf of the Board, I thank you for your support and ask you to vote in
favor of the Merger.
 
                                          Sincerely,

                                PROXY STATEMENT
 
                                ---------------
 
                           SUNGARD DATA SYSTEMS INC.
 
                                  PROSPECTUS
 
                                ---------------
 
  This Proxy Statement/Prospectus is being furnished to holders of common
stock, $0.001 par value per share ("Infinity Common Stock"), of Infinity
Financial Technology, Inc., a Delaware corporation ("Infinity"), in connection
with the solicitation of proxies by the Infinity Board of Directors for use at
Infinity's Special Meeting of Stockholders or any adjournment or postponement
thereof (the "Infinity Special Meeting"). The Infinity Special Meeting is
being called to consider and vote upon a proposal to adopt and approve the
Agreement and Plan of Merger and Reorganization, dated as of October 17, 1997,
among SunGard Data Systems Inc., a Delaware corporation ("SunGard"),
Information Data Inc., a Delaware corporation and a wholly owned subsidiary of
SunGard ("Merger Sub"), and Infinity (the "Reorganization Agreement"), and to
approve the merger of Merger Sub with and into Infinity (the "Merger").
 
  Upon consummation of the proposed Merger, Infinity will become a wholly
owned subsidiary of SunGard and each outstanding share of Infinity Common
Stock will be converted into the right to receive sixty-eight hundredths
(0.68) of a share of common stock, $0.01 par value per share, of SunGard
("SunGard Common Stock") (subject to adjustment as appropriate to reflect any
stock split, stock dividend, reverse stock split, reclassification,
recapitalization or other similar transaction involving the SunGard Common
Stock or the Infinity Common Stock between the date of the Reorganization
Agreement and the effective time of the Merger). (The fraction of a share of
SunGard Common Stock, currently 0.68, into which each share of Infinity Common
Stock will be converted pursuant to the Reorganization Agreement is referred
to as the "Exchange Ratio"). If the Merger is consummated, Infinity's 1989
Stock Option Plan, Infinity's 1993 Stock Incentive Plan and Infinity's 1996
Stock Incentive Plan (collectively, the "Infinity Stock Option Plans") will be
assumed by SunGard and each option to purchase Infinity Common Stock
outstanding under the Infinity Stock Option Plans (each, an "Infinity Option")
will be converted into an option to purchase that number of shares of SunGard
Common Stock determined by multiplying the number of shares of Infinity Common
Stock subject to such Infinity Option immediately prior to the effective time
of the Merger by the Exchange Ratio, rounded down to the next lowest whole
number of shares (with cash, less the applicable exercise price, being payable
for any fraction of a share), at an exercise price equal to the exercise price
of such option at the time of the Merger divided by the Exchange Ratio,
rounded up to the next highest cent.
 
  The obligations of SunGard and Infinity to effect the Merger and otherwise
consummate the transactions contemplated by the Reorganization Agreement are
subject to the satisfaction or waiver of various conditions, including the
adoption and approval of the Reorganization Agreement and the approval of the
Merger by holders of a majority of the outstanding shares of Infinity Common
Stock and the expiration or termination of the waiting period applicable to
the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"). The Merger will be consummated shortly after such
stockholder approval is obtained, such waiting period expires or is terminated
and the other conditions to the consummation of the Merger are satisfied or
waived. It is currently anticipated that the Merger will be consummated in
1997.
 
  This Proxy Statement/Prospectus also constitutes the prospectus of SunGard
with respect to shares of SunGard Common Stock to be issued in the Merger in
exchange for outstanding shares of Infinity Common Stock.
 
  All information contained or incorporated by reference herein concerning
SunGard has been furnished by SunGard, and all information contained or
incorporated by reference herein concerning Infinity has been furnished by
Infinity.
 
  This Proxy Statement/Prospectus and the accompanying form of proxy are first
being mailed to stockholders of Infinity on or about November  , 1997.
 
                                ---------------
 
  THE ABOVE MATTERS ARE DISCUSSED IN DETAIL IN THIS PROXY
STATEMENT/PROSPECTUS. STOCKHOLDERS OF INFINITY ARE STRONGLY URGED TO READ AND
CONSIDER CAREFULLY THIS PROXY STATEMENT/PROSPECTUS IN ITS ENTIRETY, INCLUDING
THE MATTERS REFERRED TO UNDER "RISK FACTORS" BEGINNING AT PAGE 16.
 
                                ---------------
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
  EXCHANGE COMMISSION (THE "COMMISSION") NOR  HAS THE COMMISSION PASSED UPON
    THE  ACCURACY OR  ADEQUACY  OF  THIS  PROXY STATEMENT/PROSPECTUS.  ANY

  Only Infinity stockholders of record at the close of business on November 14,
1997 (the "Record Date") are entitled to vote at the Infinity Special Meeting.
Under the Delaware General Corporation Law (the "DGCL") and the Certificate of

have agreed that, prior to the earlier of the date upon which the

                                   THE MERGER
 
GENERAL
 
  At the Effective Time (as defined below), Merger Sub will merge with and into
Infinity, the separate existence of Merger Sub will cease and Infinity will
become a wholly owned subsidiary of SunGard. It is currently anticipated that
the Effective Time will occur during       1997. In addition, the
Reorganization Agreement provides that subject to the terms and conditions
thereof, at the Effective Time, the following will occur:
 
  Conversion of Infinity Common Stock. Subject to the provisions contained in
the Reorganization Agreement relating to the payment of cash in lieu of
fractional shares, each share of Infinity Common Stock then outstanding (except
for any such shares held by Infinity as treasury stock and any such shares held
by SunGard or any subsidiary of SunGard or Infinity) will be converted into the
right to receive sixty-eight hundredths (0.68) of a share of SunGard Common
Stock (subject to adjustment as appropriate to reflect any stock split, stock
dividend, reverse stock split, reclassification, recapitalization or other
similar transaction involving the SunGard Common Stock or the Infinity Common
Stock between the date of the Reorganization Agreement and the effective time
of the Merger). (The fraction of a share of SunGard Common Stock into which
each share of Infinity Common Stock will be converted pursuant to the
Reorganization Agreement is referred to as the "Exchange Ratio").
 
  Infinity Stock Options. All rights with respect to Infinity Common Stock
under each Infinity Option then outstanding will be converted into and become
rights with respect to SunGard Common Stock, and SunGard will assume each such
Infinity Option in accordance with the terms (as in effect as of October 17,
1997) of the stock option plan under which it was issued and the stock option
agreement by which it is evidenced (subject to appropriate adjustments to the
exercise price and number of shares subject thereto based upon the Exchange
Ratio). See "The Reorganization Agreement--Stock Options; Employee Stock
Purchase Plan."
 
                                       4
<PAGE>
 
 
  Infinity Employee Stock Purchase Plan.  The Infinity 1996 Employee Stock
Purchase Plan (the "Infinity Purchase Plan") will be terminated as of the
Effective Time. The rights of participants in the Infinity Purchase Plan with
respect to any offering period then underway under the Infinity Purchase Plan
shall be determined by treating the last business day prior to the Effective
Time as the last day of such offering period and by making such other pro-rata
adjustments as may be necessary to reflect the reduced offering period but
otherwise treating such offering period as a fully effective and completed
offering period for all purposes under the Infinity Purchase Plan. See "The
Reorganization Agreement--Stock Options; Employee Stock Purchase Plan."
 
EFFECTIVE TIME OF THE MERGER; CLOSING DATE
 
  The Merger will become effective upon the filing of a Certificate of Merger
with the Secretary of State of the State of Delaware or at such later time as
may be specified in the Certificate of Merger (the "Effective Time"). The
consummation of the transactions contemplated by the Reorganization Agreement
will take place on a date to be designated by SunGard (the "Closing Date"),
which will be no later than the second business day after the satisfaction or
waiver of all of the conditions to closing set forth in the Reorganization
Agreement. Assuming that all of the conditions to the Merger are satisfied or
waived, it is anticipated that the Merger will be consummated in       1997.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
  Based upon the number of shares of Infinity Common Stock issued and
outstanding as of the Record Date, an aggregate of approximately    shares of
SunGard Common Stock will be issued to holders of Infinity Common Stock. Based
upon the number of shares of SunGard Common Stock issued and outstanding as of
the Record Date, and after giving effect to the additional shares of SunGard
Common Stock that are proposed to be issued in the Merger (and assuming no
exercise of outstanding options or rights to purchase SunGard Common Stock or
Infinity Common Stock), the former holders of Infinity Common Stock would hold
approximately  % of SunGard's total issued and outstanding shares.
 
EXCHANGE OF INFINITY STOCK CERTIFICATES
 
  As soon as practicable after the Effective Time, Norwest Bank Minnesota, N.A.
(the "Exchange Agent") will mail to the holders of Infinity Common Stock (i) a
letter of transmittal (the "Letter of Transmittal") with respect to the
surrender of valid certificates representing shares of Infinity Common Stock
("Infinity Stock Certificates") in exchange for certificates representing
SunGard Common Stock and (ii) instructions for use of the Letter of
Transmittal. INFINITY STOCKHOLDERS SHOULD NOT SURRENDER THEIR INFINITY STOCK
CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL. See "The
Reorganization Agreement--Conversion of Shares; Procedures for Exchange of
Certificates."
 
INFINITY'S REASONS FOR THE MERGER
 
  The Infinity Board of Directors considered a wide variety of information and
a number of factors in connection with its evaluation of the proposed Merger
and the Reorganization Agreement, and determined that the Merger provides an
opportunity that serves the best interests of Infinity and its stockholders.
The Infinity Board of Directors believes that the Merger may result in a number
of benefits to Infinity and its stockholders, including, among other benefits,
the following: (i) the potential synergy and compatibility between Infinity and
SunGard, based on the compatibility of the companies' product lines and the
benefits of an integration strategy in the financial services software
industry; (ii) the financial strength of SunGard that would enable the combined
company to commit greater resources to both current and emerging product
development efforts and fund the future growth of its business; (iii) the
ability to leverage SunGard's extensive sales network to increase sales of
Infinity's products; and (iv) the opportunity for Infinity, as part of the
combined company, to compete more
 
                                       5
<PAGE>
 
effectively in the increasingly competitive and rapidly changing financial
services software industry. See "Approval of the Merger and Related
Transactions--Infinity's Reasons for the Merger," and "The Infinity Special
Meeting--Board Recommendation."
 
RECOMMENDATION OF THE INFINITY BOARD OF DIRECTORS
 
  The Infinity Board of Directors has unanimously approved the Reorganization
Agreement and the Merger, and recommends a vote FOR adoption and approval of
the Reorganization Agreement and FOR approval of the Merger by the stockholders
of Infinity.
 
OPINION OF DEUTSCHE MORGAN GRENFELL INC.
 
  Deutsche Morgan Grenfell Inc. ("DMG") delivered its opinion dated October 17,
1997 (the "DMG Opinion") to the Infinity Board of Directors that, as of the
date of such opinion, the Exchange Ratio was fair from a financial point of
view to the holders of Infinity Common Stock. The full text of the DMG Opinion,
which sets forth, among other things, assumptions made, procedures followed,
matters considered and limitations on the scope of the review undertaken in
connection with the DMG Opinion, is attached hereto as Appendix B and is
incorporated herein by reference. The DMG Opinion does not constitute a
recommendation as to how any holder of Infinity Common Stock should vote at the
Infinity Special Meeting. Holders of Infinity Common Stock are urged to, and
should, read the DMG Opinion in its entirety. See "Approval of the Merger and
Related Transactions--Opinion of Deutsche Morgan Grenfell Inc."
 
SUNGARD'S REASONS FOR THE MERGER
 
  The SunGard Board of Directors considered a wide variety of information and a
number of factors in connection with its evaluation of the proposed Merger and
the Reorganization Agreement, and determined that the Merger provides an
opportunity that serves the best interests of SunGard and its stockholders. The
SunGard Board of Directors believes that the Merger may result in a number of
benefits to SunGard and its stockholders, including, among other benefits, the
following: (i) the acquisition of Infinity's products will complement and
broaden SunGard's existing product lines in the investment support systems
businesses; (ii) the acquisition of Infinity's primary product, the Infinity
Platform, should help establish SunGard as a leading provider of trading and
risk management platform and solutions software; and (iii) the combination of
the technologies and product development resources of SunGard and Infinity
should enable SunGard to respond more effectively to the continuing emergence
of trading and risk management systems. See "Approval of the Merger and Related
Transactions--SunGard's Reasons for the Merger."
 
NON-SOLICITATION
 
  Pursuant to the Reorganization Agreement, Infinity has agreed that it will
not directly or indirectly, and will not authorize or permit any of the
officers, directors, employees, agents, attorneys, accountants, advisors or
representatives (the "Representatives") of Infinity or any subsidiary of
Infinity (Infinity and each such subsidiary being referred to as the "Acquired
Corporations") directly or indirectly to (i) solicit, initiate, encourage or
induce the making, submission or announcement of any Acquisition Proposal (as
defined under "Approval of the Merger and Related Transactions--Voting
Agreements") or take any action that could reasonably be expected to lead to an
Acquisition Proposal, (ii) furnish any information regarding any of the
Acquired Corporations to any third party in connection with or in response to
an Acquisition Proposal, (iii) engage in discussions or negotiations with any
third party with respect to any Acquisition Proposal, (iv) approve, endorse or
recommend any Acquisition Proposal or (v) enter into any letter of intent or
similar document or any contract or other agreement contemplating or otherwise
relating to any Acquisition Transaction; provided, however, that: (A) no
provision in the Reorganization Agreement shall prohibit the Infinity Board of
Directors from disclosing to Infinity's stockholders a position with respect to
a tender offer pursuant to Rules 14d-9 and 14e-2 promulgated
 
                                       6
<PAGE>
 
under the Exchange Act; and (B) prior to the adoption and approval of the
Reorganization Agreement by the Required Vote, such provisions shall not
prohibit Infinity from (x) furnishing nonpublic information regarding the
Acquired Corporations to any third party in response to an Acquisition Proposal
that is submitted by such third party (and not withdrawn), or (y) entering into
discussions with any third party in response to a Superior Offer (as defined
under "The Reorganization Agreement--Covenants") that is submitted by such
third party (and not withdrawn) if, in either such case, (a) neither Infinity
nor any Representative of any of the Acquired Corporations has violated any of
the restrictions set forth above in this sentence, (b) the Infinity Board of
Directors believes in good faith, based upon the advice of outside legal
counsel, that such action is required in order for the Infinity Board of
Directors to comply with its fiduciary obligations to Infinity's stockholders
under applicable law, (c) prior to furnishing any such nonpublic information
to, or entering into discussions with, such third party, Infinity gives SunGard
written notice of the identity of such third party and of Infinity's intention
to furnish nonpublic information to, or enter into discussions with, such third
party, and Infinity receives from such third party an executed confidentiality
agreement containing limitations on the use and disclosure of all nonpublic
written and oral information furnished to such third party by or on behalf of
Infinity, and (d) prior to furnishing any such nonpublic information to such
third party, Infinity furnishes such nonpublic information to SunGard (to the
extent such nonpublic information has not been previously furnished by Infinity
to SunGard). See "The Reorganization Agreement--Non-Solicitation."

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Certain members of Infinity's management and Board of Directors may be deemed
to have certain interests in the Merger that are in addition to their interests
as stockholders of Infinity generally. The Infinity Board of Directors was
aware of these interests and considered them, among other matters, in approving
the Reorganization Agreement and the transactions contemplated thereby.
 
  Indemnification and Insurance. The Reorganization Agreement provides that all
rights to indemnification existing in favor of the persons serving as directors
and officers of Infinity as of the date of the Reorganization Agreement for
acts or omissions occurring prior to the Effective Time, as provided in
Infinity's Bylaws and in certain indemnification agreements between Infinity
and such directors and officers, will survive the Merger, and that SunGard will
cause the Surviving Corporation to perform its obligations arising thereunder
for at least six years from the Effective Time. Subject to certain limitations,
SunGard has also agreed to cause the Surviving Corporation to maintain in
effect for three years after the Effective Time a policy of directors' and
officers' liability insurance in existence at the date of the Reorganization
Agreement for the benefit of persons serving as directors and officers of
Infinity as of such date.
 
  Acceleration of Certain Stock Options. Pursuant to the terms of existing
stock option agreements, certain unvested stock options granted by Infinity and
held by three officers of Infinity will become immediately exercisable as of
the Effective Time.
 
  Employment/Severance Arrangement. SunGard expects to enter into an agreement
with Michael A. Laven, President and Chief Operating Officer of Infinity, which
is expected to provide for the full-time employment of Mr. Laven after the
Effective Time, with compensation to be specified in such agreement. The
employment agreement with Mr. Laven is also expected to provide that if Mr.
Laven's employment is terminated without "cause" prior to the third anniversary
of the date on which the Merger becomes effective, Mr. Laven will be paid an
amount equal to his annual base salary in effect at the time of such
termination; provided, however, that if less than one year of the three-year
restriction period set forth in his Noncompetition Agreement with SunGard
remains unexpired pursuant to the terms of such Noncompetition Agreement, his
annual base salary in effect at the time of such termination shall be prorated
to reflect the remaining unexpired portion of such restriction period. See
"Approval of the Merger and Related Transactions--Interests of Certain Persons
in the Merger."
 
VOTING AGREEMENTS
 
  Pursuant to the SunGard Voting Agreements, Terry H. Carlitz, Chief Financial
Officer and Vice President, Finance of Infinity, James Dorrian, Director of
Infinity, Till M. Guldimann, Executive Vice President and Director of Infinity,
Roger A. Lang, Jr., Chairman of the Board and Chief Executive Officer of
Infinity, Michael A. Laven, President, Chief Operating Officer and Director of
Infinity, Douglas M. Leone, Director of Infinity and a general partner of
several Sequoia Capital partnerships which have general partners who are
general partners of Sequoia Capital Growth Fund and Sequoia Technology Partners
III, John C. Lewis, Director of Infinity, Sequoia Capital Growth Fund and
Sequoia Technology Partners III (individually, a "Voting Agreement Stockholder"
and, collectively, the "Voting Agreement Stockholders"), who owned in the
aggregate issued and outstanding shares of Infinity Common Stock representing
approximately [46.8%] of the shares of Infinity Common Stock issued and
outstanding as of the Record Date, have agreed that, prior to the Expiration
Date, they will vote their shares of Infinity Common Stock in favor of: (i) the
Merger; (ii) the execution and delivery by Infinity of the Reorganization
Agreement; (iii) the adoption and approval of the terms of the Reorganization
Agreement; and (iv) each of the other actions contemplated by the
Reorganization Agreement and any action required in furtherance thereof. The
Voting Agreement Stockholders have also delivered to SunGard irrevocable
proxies with respect to such matters. See "Approval of the Merger and Related
Transactions--Voting Agreements."
 
                                       9
<PAGE>
 
 
AFFILIATE AGREEMENTS
 
  Certain stockholders of Infinity who may be deemed to be affiliates of
Infinity for purposes of Rule 145 under the Securities Act have executed
agreements that restrict the sale, transfer or other disposition of SunGard
Common Stock received by such stockholders in the Merger in order to comply
with the requirements of certain federal securities laws and certain pooling of
interests accounting rules. See "Approval of the Merger and Related
Transactions--Affiliate Agreements" and "--Resale of SunGard Common Stock."
 
NONCOMPETITION AGREEMENTS
 
  Till M. Guldimann, Roger A. Lang, Jr. and Michael A. Laven have each entered
into a Noncompetition Agreement with SunGard that contains provisions
restricting such employees from engaging in certain activities that are
competitive with SunGard or Infinity for a period of from two or three years
(depending upon the individual agreement) following the Effective Time. See
"Approval of the Merger and Related Transactions--Noncompetition Agreements."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The Merger is expected to be a tax-free reorganization for federal income tax
purposes, so that no gain or loss will be recognized by the Infinity
stockholders on the exchange of Infinity Common Stock for SunGard Common Stock,
except to the extent that Infinity stockholders receive cash in lieu of
fractional shares. The Reorganization Agreement does not require the parties to
obtain a ruling from the Internal Revenue Service as to the tax consequences of
the Merger. As a condition to Infinity's and SunGard's obligations to
consummate the Merger, Infinity and SunGard are to receive opinions from their
respective legal counsel that, based on certain assumptions and certifications,
the Merger will be treated as a tax-free reorganization for federal income tax
purposes. INFINITY STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS
TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE
FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES. See "Approval of the Merger
and Related Transactions--Certain Federal Income Tax Consequences."
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger is intended to be accounted for as a pooling of interests for
financial reporting purposes in accordance with generally accepted accounting
principles. SunGard's obligation to consummate the Merger is conditioned upon
receipt of (i) a letter from Ernst & Young LLP, Infinity's independent
auditors, regarding Ernst & Young LLP's concurrence with Infinity management's
conclusion that no conditions exist related to Infinity that would preclude
SunGard from accounting for the Merger as a pooling of interests, and (ii) a
letter from Coopers & Lybrand LLP, SunGard's independent public accountants, to
the effect that Coopers & Lybrand LLP concurs with SunGard management's
conclusion that SunGard may account for the Merger as a pooling of interests.
See "Approval of the Merger and Related Transactions--Anticipated Accounting
Treatment."
 
REGULATORY MATTERS
 
  Under the HSR Act, and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), the Merger may not be consummated until notifications
have been given and certain information has been furnished to the FTC and the
Antitrust Division of the Department of Justice (the "Antitrust Division"), and
specified waiting period requirements have been satisfied or early termination
of the waiting period is granted at the request of SunGard and Infinity.
SunGard and Infinity filed notification and report forms under the HSR Act with
the FTC and the Antitrust Division on November 3, 1997. These filings commenced
a 30-day waiting period under the HSR Act. If, prior to the expiration of such
period, the FTC or the Antitrust Division should request additional information
or documentary material under the HSR Act, consummation of the Merger could be
delayed until after the companies have substantially complied with the request.
There can be no assurance that a challenge to the Merger on antitrust grounds
will not be made, or if such a challenge is made, that SunGard or
 
                                       10
<PAGE>
 
Infinity would prevail or would not be required to terminate the Reorganization
Agreement. See "Approval of the Merger and Related Transactions--Regulatory
Matters."
 
ABSENCE OF APPRAISAL RIGHTS
 
  In accordance with Section 262 of the DGCL, holders of Infinity Common Stock
are not entitled to appraisal rights in connection with the Merger. See
"Approval of the Merger and Related Transactions--Absence of Appraisal Rights."

  The Merger and an investment in securities of SunGard involve certain risks

Infinity, risks associated with a fixed Exchange Ratio, risks relating to the
respective businesses of SunGard and Infinity and other risks and uncertainties

(1) The years ended December 31, 1996 and 1995 include one-time charges for
    purchased in-process research and development, merger and other costs of
    $51,083 and $4,236, respectively ($33,468 and $4,238 after-tax, or $0.39
    and $0.05 per share, respectively), and $9,618 for the six months ended
    June 30, 1997 ($5,805 after-tax, or $0.07 per share).
(2) The historical book value per common share is computed by dividing total
    stockholders' equity by the number of shares of common stock outstanding at
    the end of the period, except that the historical book value per common
    share as of December 31, 1995 and December 31, 1994 with respect to
    Infinity is computed by dividing total stockholders' equity as of such
    dates by the number of shares of common stock that would have been
    outstanding if Infinity's convertible preferred stock was converted into
    common stock. In addition, the historical book value per common share with
    respect to Infinity has been adjusted to give effect to the redemption of
    Infinity's Series B preferred stock. The pro forma book value per share is
    computed by dividing pro forma stockholders' equity by the pro forma number
    of shares of common stock as of each of the periods presented.

                                 RISK FACTORS
 
  This Proxy Statement/Prospectus contains forward-looking statements
(including those set forth or referenced in "Approval of the Merger and
Related Transactions--Background of the Merger," "--Infinity's Reasons for the
Merger," "--SunGard's Reasons for the Merger" and "--Opinion of Deutsche
Morgan Grenfell Inc.") that involve risks and uncertainties. SunGard's and
Infinity's actual results may differ materially from those anticipated in
these forward-looking statements as a result of certain risks and
uncertainties, including risks relating to: (a) the integration of SunGard and
Infinity; (b) the respective businesses of SunGard and Infinity, including
risks relating to the timing and magnitude of software sales, the timing and
scope of technological advances and the overall condition of the financial
services industry; and (c) other matters set forth in this section and
elsewhere in this Proxy Statement/Prospectus and in the documents incorporated
herein by reference. In addition to the other information in this Proxy
Statement/Prospectus, the following risk factors should be considered
carefully by Infinity stockholders in determining whether or not to vote in
favor of the adoption and the approval of the Reorganization Agreement and
approval of the Merger.
 
RISKS RELATING TO THE MERGER
 
  Uncertainty Relating to Integration. The Merger involves the integration of
two companies that have previously operated independently. Such integration
will require significant effort from each company, including the coordination
of their research and development and sales and marketing efforts. There can
be no assurance that SunGard will integrate the respective operations of
SunGard and Infinity without encountering difficulties or experiencing the
loss of Infinity or SunGard personnel or that the benefits expected from such
integration will be realized. The diversion of the attention of management and
any difficulties encountered in the transition process (including the
interruption of, or a loss of momentum in, Infinity's activities, problems
associated with integration of management information and reporting systems,
and delays in implementation of consolidation plans) could have an adverse
impact on SunGard's ability to realize anticipated synergies from the Merger.
 
  Risks Associated with Fixed Exchange Ratio. As a result of the Merger, each
outstanding share of Infinity Common Stock will be converted into the right to
receive 0.68 of a share of SunGard Common Stock (subject to adjustment as
appropriate to reflect any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction involving the
SunGard Common Stock or the Infinity Common Stock between the date of the
Reorganization Agreement and the effective time of the Merger). Because the
Exchange Ratio is fixed and will not increase or decrease due to fluctuations
in the market price of either SunGard or Infinity Common Stock, the specific
value of the consideration to be received by Infinity stockholders in the
Merger will depend on the market price of SunGard Common Stock at the
Effective Time. In the event that the market price of SunGard Common Stock
decreases or increases prior to the Effective Time, the market value at the
Effective Time of SunGard Common Stock to be received by Infinity stockholders
in the Merger would correspondingly decrease or increase. The market prices of
SunGard Common Stock and Infinity Common Stock as of a recent date are set
forth herein under "Summary--Market Price and Data," and "Comparative Per
Share Market Price Data and Dividend Policy." Infinity stockholders are
advised to obtain recent market quotations for SunGard Common Stock and
Infinity Common Stock. SunGard Common Stock and Infinity Common Stock
historically have been subject to price volatility. No assurance can be given
as to the market prices of SunGard Common Stock or Infinity Common Stock at
any time. See "Summary--Market Price and Data," and "Comparative Per Share
Market Price Data and Dividend Policy."
 
  Effect of Merger on Operating Results, Customers and Partners. Infinity
derives a significantly larger portion of its revenues from software license
fees than does SunGard. Since there are inherent difficulties in predicting
the timing and magnitude of software sales, the potential for fluctuations in
quarterly revenues and income will be higher for the combined operations after
the Merger than for SunGard alone before the Merger. Certain of Infinity's
existing customers or strategic partners may view themselves as competitors of
SunGard, and therefore determine that the Merger is competitively
disadvantageous to them. As a consequence, Infinity's
 
                                      16
<PAGE>
 
relationship with these customers or strategic partners could be adversely
affected. In addition, SunGard's relationships with certain of its customers
may be adversely affected by the Merger. Such adverse impact could result in
delayed or lost sales to either SunGard or Infinity, resulting in material
adverse financial impact.
 
  Rights of Holders of Infinity Common Stock Following the Merger. Following
the Merger, holders of Infinity Common Stock outstanding as of the Effective
Time will become holders of SunGard Common Stock. Certain differences exist
between the rights of stockholders of Infinity under Infinity's Amended and
Restated Certificate of Incorporation and Infinity's Bylaws and the rights of
stockholders of SunGard under SunGard's Restated Certificate of Incorporation
and SunGard's Bylaws. See "Comparison of Rights of Holders of SunGard Common
Stock and Holders of Infinity Common Stock."
 
RISKS RELATING TO SUNGARD'S BUSINESS
 
  Acquisitions. SunGard seeks to grow both internally and through the
acquisition of complementary businesses. SunGard's growth, in part, depends
upon the availability of suitable acquisition candidates and whether
acquisitions can be completed on acceptable terms. Competition from other
acquirors and the alternative of a public equity offering may adversely affect
both the availability and terms of future acquisitions. Further acquisitions by
SunGard may require the use of debt or equity financing. There can be no
assurance that any acquired business will perform as expected. Poor performance
by an acquired business could adversely affect SunGard's results and cause
impairment of part of SunGard's goodwill and other intangible assets related to
acquisitions accounted for as a purchase.
 
  Technological Changes. SunGard's success, in part, depends upon continued
adaptation of its proprietary software and recovery services to new computer
and telecommunications technology on a timely and cost effective basis. In
particular, rapid technological developments, which cannot be predicted, could
have a material adverse effect on SunGard's business and prospects.
 
  Product Development. SunGard must continually enhance and evolve its
proprietary software to keep pace with developments in the financial services
and healthcare industries. There can be no assurance that SunGard will be able
to update its software or develop new systems without experiencing unforeseen
delays or that newly developed products will be successfully marketed and sold.
 
  Financial Services Industry. SunGard sells most of its computer services and
software to the financial services industry and is generally dependent upon the
continued vitality of that industry. A material adverse change in the condition
of the financial services industry, such as a significant decline in securities
or derivatives trading activities or in the number or value of managed
portfolios, could have a material adverse effect on SunGard's business and
prospects.
 
  New Business Line. In 1995, SunGard established its Healthcare Information
Systems Group by acquiring two providers of work-flow management and document-
imaging systems to the healthcare industry. Recently, SunGard acquired another
company in the healthcare information systems market. Although SunGard has
experience managing software businesses, prior to 1995, SunGard had no
experience in the healthcare information systems market. In addition, a number
of SunGard's competitors in this market have substantially greater financial,
technological and marketing resources than SunGard.
 
RISKS RELATING TO INFINITY'S BUSINESS
 
  Infinity's business is subject to numerous risks, including risks that
quarterly operating results will vary from expectations due to unexpected
revenue shortfalls, changes in gross margins or other factors, risks related to
the evolving market for financial trading and risk management software, risks
related to the rapid technological change in the market for Infinity's products
and risks related to competition. A full discussion of these risks and other
risks associated with Infinity's business may be found in Infinity's
Registration Statement on Form S-1 (No. 333-8647), Annual Report on Form 10-K
for the year ended December 31, 1996 and Infinity's Quarterly Reports on Form
10-Q for the quarterly periods ended March 31, 1997 and June 30, 1997.

Infinity Common Stock outstanding as of the Record Date. Each stockholder of
record of Infinity Common Stock on the Record Date is entitled to cast one

by the SunGard Voting Agreements. In addition, subject to certain exceptions,
the Voting Agreement Stockholders have agreed not to sell, contract to sell,
pledge, grant any option to purchase or otherwise dispose of or transfer
("Transfer") any of the Subject Securities (as defined below) unless and until

Stock and all additional options, warrants, and other rights to acquire shares

BOARD RECOMMENDATION

QUORUM; ABSTENTIONS
 
  The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Infinity Common Stock entitled to vote
at the Infinity Special Meeting is necessary to constitute a quorum.
Abstentions will be counted for purposes of determining a quorum, but will
have the effect of a vote against approval of the matters being voted upon. If
an executed proxy is returned by a broker holding shares in street name which
indicates that the broker does not have discretionary authority as to certain
shares to vote on one or more matters, such shares will be considered
represented at the Infinity Special Meeting for purposes of determining a
quorum, but will not be considered to be represented at the Infinity Special
Meeting for purposes of calculating the vote with respect to such matter.
 
SOLICITATION OF PROXIES; EXPENSES
 
  Regardless of whether the Merger is consummated, each of Infinity and
SunGard will pay its own costs and expenses incurred in connection with the
Reorganization Agreement and the transactions contemplated by the
Reorganization Agreement, except that fees and expenses (other than attorneys'
fees) incurred in connection with (i) the printing, filing and mailing of the
Registration Statement and this Proxy Statement/Prospectus and (ii) the filing
of the premerger notification and report forms relating to the Merger under
the HSR Act, will be shared equally by Infinity and SunGard.
 
  Subject to the foregoing, the cost of the solicitation of proxies and all
related costs will be borne by Infinity. In addition, Infinity may reimburse
brokerage firms and other persons representing beneficial owners of shares for
their expenses in forwarding solicitation materials to such beneficial owners.
Original solicitation of proxies by mail may be supplemented by telephone,
facsimile or personal solicitation, without payment of additional
compensation, by certain directors, officers or other employees of Infinity.

                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS
 
BACKGROUND OF THE MERGER
 
  Since becoming an independent company in the early 1980s, a key element of
SunGard's corporate growth strategy has been the pursuit of business
acquisitions that would complement or expand SunGard's existing business
lines. Both SunGard and Infinity provide trading and risk management software
applications to financial institutions. Cristobal Conde, Chief Executive
Officer of SunGard's Trading Systems Group, and Roger A. Lang, Jr., Chief
Executive Officer of Infinity, have been acquainted with each other for a
number of years through common industry trade events. On June 4, 1997, Mr.
Conde met with Mr. Lang for a general discussion of their businesses. At that
meeting, Mr. Conde suggested that the two companies explore the possible
benefits of a merger.
 
  On June 20 and 23, 1997, Mr. Conde met again with Mr. Lang to discuss the
possible synergies that could be achieved from a merger involving SunGard and
Infinity, and the possible benefits that such a merger would have for the
companies' respective stockholders, customers and employees. At those
meetings, Messrs. Conde and Lang discussed the steps that would need to be
taken to determine whether the perceived benefits of a combination involving
the companies could be quantified.
 
  During a telephone conversation on July 9, 1997, Messrs. Conde and Lang
agreed that further discussions relating to a possible merger involving
SunGard and Infinity would be postponed until late August 1997 because during
July and August 1997, SunGard and Infinity both would be engaged in the
process of preliminary business and budgetary planning for 1998 for their
respective businesses.
 
  In mid August 1997, certain members of SunGard's senior management informed
certain members of the SunGard Board of Directors of the preliminary merger
discussions between SunGard and Infinity. Thereafter, from time to time, the
members of the SunGard Board of Directors were informally advised of the
progress of the discussions with Infinity.
 
  On August 22, 1997, Mr. Conde and Michael A. Laven, President and Chief
Operating Officer of Infinity, met to discuss the specific potential financial
synergies that might be derived from a merger involving SunGard and Infinity.
At a regularly scheduled meeting of the Infinity Board of Directors held on
August 26, 1997, Mr. Lang led a discussion of strategic alternatives and the
Board discussed at length the current activity within the industry towards
consolidation and the need to provide more broadly integrated solutions to
Infinity's customer base. The Infinity Board of Directors further discussed
the role of Infinity and SunGard in this consolidation and the benefits and
risks associated with various acquisition and strategic partner strategies.
 
  On September 4, 1997, Messrs. Conde and Laven met to discuss further
potential financial synergies that might be derived from a combination of
SunGard and Infinity and financial models related thereto. On September 19,
1997, Messrs. Conde, Lang and Laven and Richard Tarbox, Vice President--
Corporate Development of SunGard, met to review the analysis of such potential
financial synergies.
 
  On September 24, 1997, James Mann, Chief Executive Officer of SunGard, and
Messrs. Conde and Tarbox met with Messrs. Lang and Laven to discuss, among
other matters, the potential benefits of a possible merger, the perceived
potential impact of a merger on SunGard and Infinity and their respective
stockholders and matters relating to the valuation of Infinity. At the
conclusion of the meeting, Mr. Mann indicated that SunGard would review
further the potential synergies of the combination of the two companies and
would then contact Infinity to discuss the results of such review.
 
  On October 7, 1997, Mr. Mann discussed with Mr. Lang proposed terms of a
possible merger involving SunGard and Infinity. Among the matters discussed
were the importance to SunGard that the exchange ratio in the proposed
transaction be structured as a fixed exchange ratio and that the executive
officers and directors of Infinity sign agreements to vote their shares of
Infinity in favor of the merger.

  On October 8, 1997, the Infinity Board of Directors engaged DMG as
Infinity's financial advisor in connection with merger discussions with
SunGard. From October 9, 1997 through October 12, 1997, Mr. Tarbox and George
Boutros, of DMG, had a number of conversations regarding SunGard's proposal to
acquire Infinity. During these conversations, issues relating to, among other
matters, the valuation of Infinity and the voting agreements with Infinity's
executive officers and directors were discussed.
 
  On October 13, 1997, Messrs. Mann and Lang had a telephone conversation
concerning a possible exchange ratio proposed by SunGard, as well as several
issues with respect to employee integration and retention. Also on October 13,
1997, a special meeting of the Infinity Board of Directors was held, during
which meeting the exchange ratio proposed by SunGard was discussed.
Representatives of Morrison & Foerster LLP, Infinity's outside legal counsel,
and representatives of DMG participated in this meeting.
 
  On October 14, 1997, the SunGard Board of Directors held a special meeting
at which Mr. Mann presented management's recommendation that SunGard pursue a
merger with Infinity. After significant discussion of many matters relating to
such a merger, the SunGard Board of Directors unanimously approved a range of
acceptable exchange ratios for the merger and authorized SunGard's management
to continue to negotiate the terms of, and subject to SunGard's management's
satisfactory completion of its investigation of Infinity, to take steps
necessary to complete, such a merger. Subsequent to the SunGard Board of
Directors meeting, Mr. Mann had a telephone conversation with Mr. Lang during
which a possible exchange ratio and certain issues relating to the proposed
voting agreements were discussed. At the conclusion of such conversation,
Messrs. Mann and Lang agreed to continue to pursue a merger.
 
  On October 15, 1997, Cooley Godward LLP, SunGard's outside legal counsel
engaged for this transaction, delivered a draft reorganization agreement to
outside legal counsel to Infinity. In addition, SunGard's legal and financial
advisors continued their investigation of Infinity.
 
  Also on October 15, 1997, the Infinity Board of Directors held another
special meeting to consider the SunGard proposal to enter into a merger
transaction involving Infinity. The discussion of the Infinity Board of
Directors focused on the merits and risks associated with the SunGard proposal
and the value to Infinity's stockholders of the proposed terms of the merger.
The Infinity Board of Directors also discussed other issues relating the
proposed merger, including the structure and timing thereof.
 
  On October 16, 1997, Mr. Tarbox, Lawrence Gross, SunGard's Vice President
and General Counsel, and representatives of SunGard's outside legal counsel,
met with representatives of DMG and representatives of Infinity's outside
legal counsel, to negotiate and finalize the terms of the proposed
reorganization agreement. Among the terms discussed were a "break-up" fee
equal to approximately $12,000,000 payable to SunGard under certain conditions
if the transaction were not to close, a stock option agreement to be entered
into by certain stockholders of Infinity giving SunGard the right to purchase
each such stockholder's shares of Infinity Common Stock under certain
circumstances and the voting agreements with the executive officers and
directors of Infinity. As a result of such negotiations, SunGard agreed that a
stock option agreement would not be necessary and that a "break-up" fee of
$9,500,000 would be acceptable. Also on October 16, 1997, DMG and Terry
Carlitz discussed with representatives of SunGard certain information relating
to SunGard's results of operations and financial condition.
 
  In addition, on October 16, 1997, the Infinity Board of Directors held
another special meeting to discuss the status of continuing negotiations with
SunGard. Following the discussion of such negotiations, Mr. Boutros of DMG
gave a presentation of DMG's financial review with respect to SunGard. The
Infinity Board of Directors then discussed the merits and risks of the merger
and received a presentation by Mr. Boutros regarding the terms of the merger.
At the conclusion of such presentation, DMG provided the Infinity Board of
Directors with its oral fairness opinion, which opinion was later confirmed in
writing in the DMG Opinion. Also on October 16, 1997, SunGard held a special
meeting of the SunGard Board of Directors to report to the SunGard Board of
Directors the results of SunGard's management's investigation of Infinity and
to review the terms of the proposed
 
                                      23
<PAGE>
 
merger with Infinity. At the conclusion of that meeting, the SunGard Board of
Directors reapproved the proposed merger involving SunGard and Infinity.
 
  On October 17, 1997, the Infinity Board of Directors held another special
meeting to review the terms of the Reorganization Agreement. After a review
and discussion of the terms of the Reorganization Agreement, and discussions
regarding the financial and other effects the proposed merger would have on
Infinity's stockholders, employees and customers, the Infinity Board of
Directors unanimously approved the Merger and authorized the officers of
Infinity to finalize and execute the Reorganization Agreement.
 
  The definitive Reorganization Agreement was executed on behalf of SunGard,
Infinity and Merger Sub before the commencement of the business day on October
17, 1997.
 
INFINITY'S REASONS FOR MERGER
 
  The Infinity Board of Directors believes that, despite its success to date,
increasing competition and industry consolidation would make it increasingly
difficult for Infinity to grow its business as a relatively small independent
company competing with larger companies with substantially greater resources
and broader, integrated product offerings. Infinity's management has
considered the alternatives of either acquiring smaller companies that could
extend the product offering and enhance the distribution of Infinity products
and services, or merging with a larger company. In the industry environment
referred to above, the Infinity Board of Directors identified several
potential benefits for the Infinity stockholders, employees and customers that
it believes would result from the Merger. These potential benefits include:
 
  -- The potential synergy and compatibility between Infinity and SunGard,
     based on the compatibility of the companies' product lines;
 
  -- The benefits of an integration strategy in the financial services
     software industry;
 
  -- The financial strength of SunGard that would enable the combined company
     to commit greater resources to both current and emerging product
     development efforts and to fund the future growth of the combined
     company's business;
 
  -- The ability to leverage SunGard's extensive sales network to increase
     sales of Infinity's products; and
 
  -- The opportunity for Infinity, as part of the combined company, to
     compete more effectively in the increasingly competitive and rapidly
     changing financial services software industry.
 
  In the course of its deliberations during the Infinity Board of Directors
meetings, held on October 13, October 15, October 16 and October 17, 1997, the
Infinity Board of Directors reviewed with Infinity's management a number of
additional factors relevant to the Merger, including the strategic overview
and prospects for Infinity, its products and its finances. The Infinity Board
of Directors also considered, among other matters:
 
  -- Information concerning SunGard's and Infinity's respective businesses,
     prospects, financial performance and condition, operations, technology,
     product lines, management and competitive position;
 
  -- The financial condition, results of operations and businesses of SunGard
     and Infinity before and after giving effect to the Merger;
 
  -- Current financial market conditions and historical market prices,
     volatility and trading information with respect to SunGard Common Stock
     and Infinity Common Stock;
 
  -- The consideration to be received by Infinity stockholders in the Merger
     and the fact that the market value of the SunGard Common Stock to be
     issued in exchange for each share of Infinity Common Stock represented a
     significant premium over the recent price range of the Infinity Common
     Stock (the Merger consideration represented a premium of approximately
     19% over the closing sales price of $13.75 per share of Infinity Common
     Stock on October 16, 1997, the last trading day prior to the
     announcement of the Merger);
 
                                      24
<PAGE>
 
  -- A comparison of selected recent acquisition and merger transactions in
     the industry;
 
  -- The belief that the terms of the Reorganization Agreement, including the
     parties' mutual representations, warranties and covenants, are
     reasonable and the fact that the Reorganization Agreement did not
     contain any extraordinary conditions on SunGard's obligations to
     consummate the Merger;
 
  -- The ability of the Infinity Board of Directors to enter into discussions
     with a person or entity in response to a Superior Offer (as defined
     under "The Reorganization Agreement--Additional Covenants of the
     Parties") that is submitted by such person or entity if, among other
     things, the Infinity Board of Directors believes in good faith, based
     upon the advice of its outside legal counsel, that such action is
     required in order for the Infinity Board of Directors to comply with its
     fiduciary obligations to Infinity's stockholders under applicable law;
 
  -- The expected tax and accounting treatment of the Merger;
 
  -- The DMG Opinion rendered at the October 17, 1997 meeting of the Infinity
     Board of Directors that, based upon and subject to the various
     conditions set forth in the DMG Opinion, the Exchange Ratio was fair to
     holders of Infinity Common Stock from a financial point of view as of
     October 17, 1997;
 
  -- The impact of the Merger upon Infinity's customers and employees; and
 
  -- Reports from management, financial advisors and legal advisors as to the
     results of their investigation of SunGard.
 
  The Infinity Board of Directors also considered a number of potentially
negative factors in its deliberations concerning the Merger, including, but not
limited to:
 
  -- The loss of control over the future operations of Infinity following the
     Merger;
 
  -- The risk that the benefits sought to be achieved in the Merger will not
     be achieved;
 
  -- The fixed nature of the Exchange Ratio and the resulting risk that it
     will not adjust for subsequent price fluctuations; and
 
  -- The other risks described above under "Risk Factors."
 
  The Infinity Board of Directors discussed with management the prospects for
combinations with companies other than SunGard and the possibility that the
benefits described above could be achieved through any such combinations, as
well as the risks and benefits of a stand-alone strategy.
 
  The foregoing discussion of information and factors considered by the
Infinity Board of Directors is not intended to be exhaustive but is believed to
include all material factors considered by the Infinity Board of Directors. In
view of the wide variety of factors considered by the Infinity Board of
Directors, the Infinity Board of Directors did not find it practicable to
quantify or otherwise assign relative weight to the specific factors
considered. However, after taking into account all of the factors set forth
above, the Infinity Board of Directors unanimously agreed that the
Reorganization Agreement and the consummation of the Merger were fair to, and
in the best interests of, Infinity and its stockholders and that Infinity
should proceed with the Merger.
 
SUNGARD'S REASONS FOR THE MERGER
 
  The SunGard Board of Directors has unanimously determined that the terms of
the Reorganization Agreement and the Merger are fair to, and in the best
interests of, SunGard and its stockholders. In reaching its determination, the
SunGard Board of Directors consulted with SunGard's management, as well as its
legal counsel and accountants, and gave significant consideration to a number
of factors bearing on its decision. The following are the reasons the SunGard
Board of Directors believes the Merger will be beneficial to SunGard and its
stockholders:
 
  -- SunGard seeks to grow both internally and through the acquisition of
     complementary businesses. Infinity's products, which provide customers
     with a foundation to rapidly develop, deploy and modify trading and risk
     management systems, will complement and broaden SunGard's existing
     product lines in the investment support systems businesses.
 
                                       25
<PAGE>
 
  -- SunGard sells its computer services and software to the financial
     services industry and believes that Infinity's products will enhance
     SunGard's ability to service that industry. The demand for trading and
     risk management systems by the financial services industry has grown
     significantly over the past several years; financial institutions
     worldwide have increasingly invested financial and other resources in
     the development and acquisition of trading and risk management
     technology. SunGard believes that Infinity's primary product, the
     Infinity Platform, should position SunGard to take advantage of this
     trend and should help establish SunGard as a leading provider of trading
     and risk management platform and solutions software.
 
  -- Infinity's business strategy is consistent with SunGard's goal to
     continue product unification and enhancement efforts to provide
     customers with access to multiple systems and data through common
     graphical interfaces and shared databases. Infinity products are
     characterized by an open systems, client/server architecture running on
     the UNIX and Windows NT Operating Systems and on leading relational
     database management systems.
 
  -- The combination of the technologies and product development resources of
     SunGard and Infinity should enable SunGard to respond more effectively
     to the rapid technological change and continuing emergence of trading
     and risk management systems.
 
  -- SunGard believes there is a significant potential enhancement of the
     strategic and market position of the combined entity beyond that
     achievable by SunGard alone.
 
  In addition to the reasons set forth above, in the course of its
deliberations concerning the Merger, the SunGard Board of Directors consulted
with SunGard's management, legal counsel and accountants and reviewed a number
of other factors relevant to the Merger, including:
 
  -- Information concerning the business, assets, operations, properties,
     management, financial condition, operating results, competitive position
     and prospects of SunGard and Infinity;
 
  -- The historical market prices and trading information with respect to
     SunGard Common Stock and Infinity Common Stock;
 
  -- The expected tax and accounting treatment of the Merger;
 
  -- Reports from legal counsel on specific terms of the Reorganization
     Agreement and the voting agreements executed by certain directors,
     officers and other affiliates of Infinity; and
 
  -- SunGard's belief that the management styles and corporate cultures of
     the two companies would be complementary.
 
  The SunGard Board of Directors also considered a number of potentially
negative factors in its deliberations concerning the Merger, including:
 
  -- The possibility of management disruption associated with the Merger and
     the risk that key technical and management personnel of Infinity or
     SunGard might not continue with Infinity or SunGard;
 
  -- The possibility that the Merger might adversely affect Infinity's or
     SunGard's relationship with certain of their respective customers;
 
  -- The risk that the potential benefits of the Merger might not be
     realized; and
 
  -- The fixed nature of the Exchange Ratio and the resulting risk that it
     will not adjust for subsequent price fluctuations.
 
  The SunGard Board of Directors concluded, however, that the benefits of the
transaction to SunGard and its stockholders outweighed the risks associated
with the foregoing factors.
 
  The foregoing discussion of the information and factors considered by the
SunGard Board of Directors is not intended to be exhaustive but is believed to
include all material factors considered by the SunGard Board of Directors. In
view of the wide variety of factors considered by the SunGard Board of
Directors, the SunGard Board of Directors did not find it practicable to
quantify or otherwise assign relative weight to the specific factors
 
                                       26

considered. However, after taking into account all of the factors set forth
above, the SunGard Board of Directors unanimously agreed that the
Reorganization Agreement and the consummation of the Merger were fair to, and
in the best interests of, SunGard and its stockholders and that SunGard should
proceed with the Merger.
 
OPINION OF DEUTSCHE MORGAN GRENFELL INC.
 
  Infinity retained DMG to act as its financial advisor in connection with the
Merger. DMG was selected by the Infinity Board of Directors to act as
Infinity's financial advisor based on DMG's qualifications, expertise and
reputation and relationship with Infinity.
 
  At the meeting of the Infinity Board of Directors on October 16, 1997, DMG
rendered its oral opinion, subsequently confirmed in writing on October 17,
1997, that, as of such date, based upon and subject to the various
considerations set forth in the DMG Opinion, the Exchange Ratio was fair from
a financial point of view to the holders of Infinity Common Stock.
 
  The full text of the DMG Opinion, which sets forth, among other things,
assumptions made, procedures followed, matters considered, and limitations on
the scope of the review undertaken by DMG in rendering the DMG Opinion, is
attached as Appendix B to this Proxy Statement/Prospectus. Infinity
stockholders are urged to read the DMG Opinion carefully and in its entirety.
DMG did not recommend to Infinity that any specific exchange ratio constituted
the appropriate exchange ratio for the Merger. The DMG Opinion addresses only
the fairness of the Exchange Ratio from a financial point of view to the
holders of Infinity Common Stock as of the date of the DMG Opinion, and does
not constitute a recommendation to any stockholder as to how such stockholder
should vote at the Infinity Special Meeting. The summary of the DMG Opinion
set forth in this Proxy Statement/Prospectus is qualified in its entirety by
reference to the full text of the DMG Opinion.
 
  In rendering the DMG Opinion, DMG, among other things: (i) analyzed certain
publicly available financial statements and other information of SunGard and
Infinity, respectively; (ii) analyzed certain internal financial statements
and other financial and operating data concerning Infinity prepared by the
management of Infinity; (iii) analyzed certain financial projections relating
to Infinity prepared by the managements of Infinity and SunGard; (iv)
discussed the past and current operations and financial condition and the
prospects of Infinity with senior executives of Infinity; (v) analyzed certain
internal financial statements and other financial and operating data
concerning SunGard prepared by the management of SunGard; (vi) discussed the
past and current operations and financial condition and the prospects of
SunGard with senior executives of SunGard; (vii) analyzed the pro forma impact
of the Merger on the earnings per share and consolidated capitalization of
SunGard; (viii) reviewed the reported prices and trading activity for the
Infinity Common Stock; (ix) compared the financial performance of Infinity and
the prices and trading activity of the Infinity Common Stock with that of
certain other comparable publicly-traded companies and their securities; (x)
reviewed the reported prices and trading activity for the SunGard Common
Stock; (xi) compared the financial performance of SunGard and the prices and
trading activity of the SunGard Common Stock with that of certain other
comparable publicly-traded companies and their securities; (xii) reviewed the
financial terms, to the extent publicly available, of certain comparable
merger and acquisition transactions; (xiii) reviewed and discussed with the
senior management of Infinity (a) the strategic rationale for the Merger and
their assessment of the synergies and other benefits expected to be derived
from the Merger and (b) certain alternatives to the Merger; (xiv) participated
in discussions and negotiations among representatives of Infinity and SunGard
and their respective legal advisors; (xv) reviewed the Reorganization
Agreement, and certain related agreements; and (xvi) performed such other
analyses and considered such other factors as DMG deemed appropriate.
 
  In rendering the DMG Opinion, DMG assumed and relied upon, without
independent verification, the accuracy and completeness of the information
reviewed by it for the purposes of the DMG Opinion. DMG was not provided with,
and therefore did not review, any internal financial projections or forecasts
relating to future operations or prospects of SunGard, and therefore, upon the
advice of SunGard, DMG assumed that the publicly available estimates of
research analysts were a reasonable basis upon which to evaluate and analyze
the future financial performance of SunGard. DMG assumed that the financial
projections for Infinity were reasonably
 
                                      27
<PAGE>
 
prepared on bases reflecting the best currently available estimates and
judgments of the future financial performance of Infinity. DMG has not made
any independent valuation or appraisal of the assets, liabilities or
technology of SunGard or Infinity, respectively, nor has DMG been furnished
with any such appraisals. DMG has assumed that the Merger will be accounted
for as a pooling of interests business combination in accordance with U.S.
Generally Accepted Accounting Principles and will be consummated in accordance
with the terms set forth in the Reorganization Agreement. The DMG opinion is
necessarily based on economic, market and other conditions as in effect on,
and the information made available to DMG as of, the date of the DMG Opinion.
 
  The following is a summary of the analysis performed by DMG in preparation
of the DMG Opinion and reviewed with the Infinity Board of Directors at
meetings held on October 13, 1997 and October 16, 1997.
 
  Comparative Stock Price Performance. As part of its analysis, DMG reviewed
the recent stock price performance of the SunGard Common Stock and the
Infinity Common Stock and compared such performance with that of other
companies involved in client/server software used primarily in the financial
services industry and with that of the Nasdaq composite and the S&P 500. DMG
observed that during the period from October 25, 1996 (the date of the Initial
Public Offering for Infinity (the "Infinity IPO")) to October 10, 1997, the
market price of the Infinity Common Stock decreased 17.8%, compared with
increases of 42.2% for the Nasdaq composite, 40.5% for the S&P 500 index,
16.2% for C-ATS Software Inc. ("C-ATS"), and 15.2% for SunGard, and decreases
of 9.3% for PegaSystems Inc. ("PegaSystems") and 9.8% for Advent Software,
Inc. ("Advent"). DMG noted that over such period, the Infinity Common Stock
underperformed relative to the common stock of C-ATS, SunGard, PegaSystems,
Advent and relative to the Nasdaq composite and the S&P 500 index. In
addition, DMG reviewed the stock price performance of the SunGard Common Stock
and compared it to the stock price performance of other companies which DMG
deemed comparable based on their revenue stream and growth history. DMG
observed that during the period from January 1, 1990 to October 10, 1997, the
SunGard Common Stock price increased 314.7% compared to an increase of 481.0%
for Cadence Design Systems, Inc., 347.8% for Automatic Data Processing, Inc.
(assuming reinvestment of dividends paid), 282.4% for the Nasdaq index and
239.0% for the S&P 500.
 
  Historical Exchange Ratio Analysis. DMG reviewed the historical trading
prices for the Infinity Common Stock and the SunGard Common Stock, separately,
and in comparison to each other. DMG also reviewed the ratios of the daily
closing prices of the Infinity Common Stock to the SunGard Common Stock for
each day over various periods, starting at October 25, 1996 (the date of the
Infinity IPO) and ending October 16, 1997 (the date of DMG's presentation of
the DMG Opinion to the Infinity Board of Directors) and computed the premiums
represented by the Exchange Ratio over the average of these ratios. The
average of the ratios of the daily closing stock prices of the Infinity Common
Stock to the SunGard Common Stock for the various periods ending on October
16, 1997 were 0.720 for the period since October 25, 1996; 0.669 for the
previous 180 trading days; 0.582 for the previous 90 trading days; 0.528 for
the previous 60 trading days; 0.515 for the previous 45 trading days; 0.521
for the previous 30 trading days; 0.571 for the previous 10 trading days; and
0.571 for October 16, 1997. DMG observed that the Exchange Ratio represented a
premium/(discount) of (5.6%), 1.7%, 16.9%, 28.8%, 32.0%, 30.6%, 19.0% and
19.0%, respectively, over the aforementioned ratios of the prices of the
Infinity Common Stock and the SunGard Common Stock.
 
  Premium Analysis. DMG reviewed four stock-for-stock acquisition transactions
involving companies in the enterprise software sector, 25 other stock-for-
stock acquisition transactions involving companies in the software sector and
36 other stock-for-stock acquisition transactions involving companies in the
technology sector since 1987, none of which were deemed directly comparable to
the Merger. For the four stock-for-stock transactions involving companies in
the enterprise software sector, such analysis showed transaction exchange
ratios resulting in average premiums/(discounts) of approximately (10.1%),
6.2%, 12.4%, 20.7%, 20.1% and 20.6% over the average of the ratios of the
closing stock prices of the companies involved in such mergers over the one
year, 90 day, 60 day, 30 day, 10 day and one day periods ending the day
preceding the public announcement of these transactions, respectively. For the
25 other stock-for-stock acquisition transactions in the software sector, DMG
observed transaction exchange ratios resulting in average premiums of
approximately 21.0%, 31.8%, 36.0%, 41.1%, 40.3% and 34.3% over the average of
the ratios of the closing stock prices of the
 
                                      28
<PAGE>
 
companies involved in such mergers over the aforementioned periods,
respectively. For the 36 other stock-for-stock acquisition transactions in the
technology sector, DMG observed transaction exchange ratios resulting in
average premiums of approximately 17.3%, 31.2%, 36.3%, 37.5%, 33.9% and 27.8%
over the average of the ratios of the closing stock prices of the companies
involved in such mergers over the aforementioned periods, respectively. DMG
observed that the Exchange Ratio represented average premiums/(discounts) of
approximately (5.6%), 16.9%, 28.8%, 30.6%, 19.0% and 19.0% over the average of
the ratios of the daily closing stock prices of the Infinity Common Stock to
the SunGard Common Stock for the respective comparable periods ending on
October 16, 1997.
 
  Contribution Analysis. DMG analyzed the pro forma contribution by each of
SunGard and Infinity to the total revenue, gross profit, operating income and
net income of the combined company (adjusted to reflect the companies'
respective net cash balances) if the Merger were to be consummated. DMG
observed that for the 1997 and 1998 calendar years, based upon research
analyst estimates for both companies, Infinity would contribute approximately
8.5% and 10.2% of total revenue, respectively; 11.4% and 13.8% of gross
profit, respectively; 8.7% and 10.7% of operating income, respectively; and
10.6% and 13.4% of net income, respectively, of the combined company. DMG
observed that the median of these contribution percentages was 10.6% which
implied an exchange ratio of 0.498. These figures compared to the pro forma
fully diluted ownership of the Infinity stockholders in the combined company
(assuming the Merger were to be consummated) of 14.0% based on the Exchange
Ratio. DMG observed that the contribution analysis does not take into account
the different multiples of revenue or operating income that the market
ascribes to SunGard and Infinity.
 
  Peer Group Comparison. DMG compared certain information relating to Infinity
and SunGard with a group of companies involved in the application
software/tools industry and the information/data processing industry. Such
information included, among other things, market valuation, stock price as a
multiple of earnings per share, aggregate market capitalization as a multiple
of revenues and stock price as a multiple of projected earnings per share over
forecasted long-term growth rate ("PEG"). The multiples are based on a
compilation of publicly available information and consensus forecasts by
securities research analysts. In particular, such comparison showed that as of
October 10, 1997, Infinity and SunGard traded at 26.2 times and 21.7 times
projected calendar year 1998 earnings, respectively; 4.7 times and 1.4 times
latest twelve months revenue, respectively; and 0.58 times and 1.21 times
calendar year 1998 PEG, respectively. As of October 10, 1997, the group of
companies involved in the application software/tools industry traded at a
median of 32.7 times projected calendar year 1998 earnings, 5.8 times latest
twelve months revenue and 0.95 times calendar year 1998 PEG. As of October 10,
1997, the group of companies involved in the information/data processing
industry traded at a median of 25.0 times projected calendar year 1998
earnings, 3.4 times latest twelve months revenue and 1.11 times calendar year
1998 PEG.
 
  Selected Precedent Transactions. DMG reviewed 17 acquisition transactions
involving companies in the enterprise software sector and 93 acquisition
transactions involving companies in the software industry (including the
enterprise software sector). DMG observed that in the enterprise software
sector, for the 17 transactions (all of which had information publicly
available) the median of the range of multiples of aggregate value to latest
twelve months revenue and operating income was 4.3 times and 29.0 times,
respectively and the median price to next twelve months earnings multiple was
31.0 times. DMG observed that in the software industry, for the 70
transactions for which such information was publicly available, the median of
the range of multiples of aggregate value to latest twelve months revenue and
operating income was 3.7 times and 30.5 times, respectively and the median
price to next twelve months earnings multiple was 31.5 times. DMG compared
these multiples to the multiples implied by the Merger of aggregate value to
latest twelve months revenue and operating income of 5.8 times and 32.5 times,
respectively and price to calendar year 1997 and 1998 earnings multiples of
43.4 times and 30.9 times, respectively.
 
  Potential Future Share Price Analysis. DMG computed equivalent per share
values for Infinity on a standalone basis. Such analysis was based on a range
of earnings estimates for Infinity based upon publicly available securities
analyst estimates as well as a sensitivity case assuming discounted earnings.
The analysis was also based on a range of one-year forward price to earnings
multiples of 15 to 30 times. Equivalent share
 
                                      29
<PAGE>
 
prices were then computed for Infinity one and two years from the date of the
analysis which were then discounted back to the present at discount rates of
0.0%, 18.0% and 25.0%. Based on a range of forecasted Infinity standalone
earnings, this analysis resulted in a present value per share to holders of
Infinity Common Stock ranging from $7.90 to $33.43. In addition, DMG computed
earnings and revenue that would be required by Infinity on a standalone basis
to achieve the value implied by the Merger. For a range of prices implied by
the Merger, ranging from $16.00 to $18.00 and a range of growth rates ranging
from 16% to 20% for stock of the combined company, DMG computed 1999 stock
price values for the Infinity Common Stock. Based on these 1999 stock prices,
and forward EPS multiples of 20.0 times and 25.9 times and operating margins
of 17.0% and 18.0%, DMG computed the required Infinity calendar year 2000
earnings and implied revenue to achieve the 1999 stock prices. Based on the
range of assumptions, the calendar year 2000 EPS and revenue required ranged
from $0.83 to $1.30 and $174.1 million to $287.9 million, respectively.
 
  Pro Forma Analysis of the Merger. DMG analyzed certain pro forma effects of
the Merger on the earnings and capitalization of SunGard. Such analysis was
based on First Call consensus estimates for SunGard and Infinity. Based on
such analysis, DMG observed that, based on the Exchange Ratio and assuming
that the Merger was treated as a pooling of interests business combination for
accounting purposes (and assuming no cost or revenue synergies), the Merger
would result in earnings per share dilution for SunGard of (4.4%) and (2.3%)
for the calendar years 1998 and 1999, respectively. The analysis was also
performed assuming a range of cost and revenue synergies. Based on such
analysis and similar assumptions, DMG observed that the Merger would result in
earnings per share (dilution) / accretion for calendar year 1998 ranging from
(4.4%) to 3.3%.
 
  In connection with the review of the Merger by the Infinity Board of
Directors, DMG performed a variety of financial and comparative analyses for
purposes of the DMG Opinion. While the foregoing summary describes all
material analyses and factors reviewed by DMG with the Infinity Board of
Directors, it does not purport to be a complete description of the
presentations by DMG to the Infinity Board of Directors or the analyses
performed by DMG in arriving at the DMG Opinion. The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to partial
analysis or summary description. DMG believes that its analyses must be
considered as a whole and that selecting portions of its analyses and of the
factors considered by it, without considering all analyses and factors, could
create a misleading view of the processes underlying the DMG Opinion. In
performing its analyses, DMG made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond the control of SunGard or Infinity. Any
estimates contained therein are not necessarily indicative of future results
or actual values, which may be significantly more or less favorable than those
suggested by such estimates. Furthermore, the analyses performed by DMG are
not necessarily indicative of actual values or actual future results, which
may be significantly more or less favorable than suggested by such analyses.
In addition, analyses relating to the value of businesses or assets do not
purport to be appraisals or to necessarily reflect the prices at which
businesses or assets may actually be sold. The analyses performed were
prepared solely as part of DMG's analysis of the fairness of the Exchange
Ratio, from a financial point of view, to the holders of Infinity Common Stock
and were provided to the Infinity Board of Directors in connection with the
delivery of the DMG Opinion.
 
  DMG is an internationally recognized investment banking and advisory firm.
DMG, as part of its investment banking business, is continuously engaged in
the valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. In the ordinary course of its
business, DMG may actively trade the securities and loans of Infinity and
SunGard for its own account and for the accounts of its customers and,
accordingly, may at any time hold a long or short position in such securities
and loans.
 
  Infinity has agreed to pay DMG a fee for its financial advisory services in
connection with the Merger, including, among other things, rendering the DMG
Opinion and making the presentation referred to above. Pursuant to a letter
agreement between Infinity and DMG dated August 25, 1997, Infinity has agreed
to pay DMG (i) in the event the Merger is consummated, a transaction fee of
$3.1 million or (ii) in the event the Merger is not consummated, an advisory
fee of between $50,000 and $75,000. In addition, Infinity has agreed to
reimburse
 
                                      30
<PAGE>
 
DMG for its reasonable out-of-pocket expenses (including fees and expenses of
its legal counsel) incurred in connection with its engagement, and to
indemnify DMG and certain related persons against certain liabilities and
expenses arising out of or in conjunction with its rendering of services under
its engagement, including certain liabilities under the federal securities
laws.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Officers and Directors of Infinity. Certain members of Infinity's management
and Board of Directors may be deemed to have certain interests in the Merger
that are in addition to their interests as stockholders of Infinity generally.
The Infinity Board of Directors was aware of these interests and considered
them, among other matters, in approving the Reorganization Agreement and the
transactions contemplated thereby.
 
  Indemnification and Insurance. The Reorganization Agreement provides that
all rights to indemnification existing in favor of the persons serving as
directors and officers of Infinity as of the date of the Reorganization
Agreement for acts or omissions occurring prior to the Effective Time, as
provided in Infinity's Bylaws and in certain indemnification agreements
between Infinity and such directors and officers, will survive the Merger, and
that SunGard will cause the Surviving Corporation to perform its obligations
arising thereunder for at least six years from the Effective Time. Subject to
certain limitations, SunGard has also agreed to cause the Surviving
Corporation to maintain in effect for three years after the Effective Time the
policy of directors' and officers' liability insurance in existence at the
date of the Reorganization Agreement for the benefit of persons serving as
directors and officers of Infinity as of such date. See "The Reorganization
Agreement--Indemnification and Insurance."
 
  Options under the Infinity Stock Option Plans. At the Effective Time, each
outstanding Infinity Option issued pursuant to the Infinity Stock Option Plans
will be assumed by SunGard. Each Infinity Option so assumed will continue to
have, and be subject to, the same terms and conditions set forth in the stock
option plan under which it was issued and the stock option agreement by which
it is evidenced (subject to appropriate adjustments to the exercise price and
number of shares subject thereto based upon the Exchange Ratio). Ms. Carlitz,
Mr. Guldimann, and Mr. Laven hold options to purchase 240,000, 700,000 and
240,000 shares, respectively, of Infinity Common Stock pursuant to stock
option agreements which provide for the acceleration of such options upon the
occurrence of a change of control of Infinity. The Merger will constitute such
a change of control. Assuming that the Merger is consummated on    , 1997,
[4,167], [25,000] and [20,833] of such options held respectively by Ms.
Carlitz, Mr. Guldimann and Mr. Laven, which would not have been vested if a
change of control of Infinity were not to occur, will become immediately
exercisable as of the Effective Time.
 
  Employment/Severance Arrangement. SunGard expects to enter into an agreement
with Michael A. Laven, President and Chief Operating Officer of Infinity,
which is expected to provide for the full-time employment of Mr. Laven after
the Effective Time, at a base salary of $235,000 per year. The employment
agreement with Mr. Laven is also expected to provide that if Mr. Laven's
employment is terminated without "cause" prior to the third anniversary of the
date on which the Merger becomes effective, Mr. Laven will be paid an amount
equal to his annual base salary in effect at the time of such termination;
provided, however, that if less than one year of the three-year restriction
period set forth in his Noncompetition Agreement with SunGard remains
unexpired pursuant to the terms of such Noncompetition Agreement, his annual
base salary in effect at the time of such termination shall be prorated to
reflect the remaining unexpired portion of such restriction period. See
"Approval of the Merger and Related Transactions--Noncompetition Agreements."
 
  Officers and Directors of SunGard. No officer or director of SunGard has any
interest in the Merger that is in addition to his or her interest as a
stockholder of SunGard generally.
 
VOTING AGREEMENTS
 
  Pursuant to the SunGard Voting Agreements, the Voting Agreement Stockholders
who owned in the aggregate issued and outstanding shares of Infinity Common
Stock representing approximately [46.8%] of the shares of Infinity Common
Stock issued and outstanding as of the Record Date, have agreed that, prior to
the
 
                                      31
<PAGE>
 
Expiration Date, they will vote their shares of Infinity Common Stock in favor
of: (i) the Merger; (ii) the execution and delivery by Infinity of the
Reorganization Agreement; (iii) the adoption and approval of the terms of the
Reorganization Agreement; and (iv) each of the other actions contemplated by
the Reorganization Agreement and any action required in furtherance thereof.
The Voting Agreement Stockholders have also delivered to SunGard irrevocable
proxies with respect to the matters covered by the SunGard Voting Agreements.
In addition, subject to certain exceptions, the Voting Agreement Stockholders
have agreed not to Transfer any Subject Securities owned by them unless and
until the proposed transferee of such Subject Securities shall have (i)
executed a counterpart of the SunGard Voting Agreement and the corresponding
irrevocable proxy and (ii) agreed to hold such Subject Securities subject to
all of the terms and conditions of the SunGard Voting Agreement.
 
  The Voting Agreement Stockholders have also agreed that, during the period
commencing on the date of the Voting Agreement and ending on the Expiration
Date, they will not, directly or indirectly, and will not authorize any of
their Representatives to: (i) solicit, initiate or encourage the making or
announcement of an Acquisition Proposal (as defined below) or take any action
that could reasonably be expected to lead to an Acquisition Proposal; (ii)
furnish any nonpublic information regarding Infinity or any of its
subsidiaries to any person in connection with an actual or potential
Acquisition Proposal; or (iii) engage in discussions with any person regarding
an Acquisition Proposal. The Voting Agreement Stockholders have also agreed to
cease any existing discussions with any person that relate to an Acquisition
Proposal.
 
  Each SunGard Voting Agreement also provides that the Voting Agreement
Stockholder who is a party thereto will hold harmless and indemnify SunGard
from and against certain damages which are incurred by SunGard that arise from
any breach of any representation, warranty, covenant or obligation of the
Voting Agreement Stockholder contained therein.
 
  An "Acquisition Proposal" is any offer, proposal or inquiry (other than an
offer, proposal or inquiry by SunGard) contemplating or otherwise relating to
any transaction or series of transactions (an "Acquisition Transaction")
involving: (i) any merger, consolidation, share exchange, business
combination, issuance of securities, acquisition of securities, tender offer,
exchange offer or other similar transaction (a) in which Infinity or any of
its subsidiaries is a constituent corporation, (b) in which an individual or
entity or "group" (as defined in the Exchange Act and the rules promulgated
thereunder) of individuals or entities directly or indirectly acquires
Infinity or more than 50% of Infinity's business or directly or indirectly
acquires beneficial or record ownership of securities representing more than
20% of the outstanding securities of any class of voting securities of
Infinity or any of its subsidiaries, or (c) in which Infinity or any of its
subsidiaries issues securities representing more than 20% of the outstanding
securities of any class of voting securities of Infinity; (ii) any sale,
lease, exchange, transfer, license, acquisition or disposition of more than
50% of the assets of Infinity; or (iii) any liquidation or dissolution of
Infinity.
 
AFFILIATE AGREEMENTS
 
  It is a condition to consummation of the Merger that each person who could
reasonably be determined to be an "affiliate," as such term is defined in Rule
145 promulgated under the Securities Act, of Infinity ("Affiliate") execute an
agreement that prohibits, during the period from the date 30 days prior to the
date of consummation of the Merger through the date on which financial results
covering at least 30 days of post-Merger combined operations of SunGard and
Infinity have been published by SunGard (within the meaning of the applicable
pooling of interests accounting requirements): (i) the sale, transfer or other
disposition or reduction of such Affiliate's interest in or risk relating to
(A) any capital stock of Infinity, except pursuant to and upon consummation of
the Merger, or (B) any option or other right to purchase any shares of capital
stock of Infinity, except pursuant to and upon consummation of the Merger; and
(ii) the sale, transfer or other disposition or reduction of such Affiliate's
interest in or risk relating to (A) any shares of capital stock of SunGard or
(B) any option or other right to purchase any shares of capital stock of
SunGard.

<PAGE>
 
NONCOMPETITION AGREEMENTS
 
  Till M. Guldimann, Roger A. Lang, Jr. and Michael A. Laven (the "Noncompete
Employees"), each have entered into a Noncompetition Agreement with SunGard (a
"Noncompetition Agreement"). The Noncompetition Agreements contain provisions
restricting such Noncompete Employees, for either two or three years
(depending on the individual agreement) following the Effective Time (the
"Restriction Period") from (i) engaging in any business that is competitive
with Infinity's business, as engaged in by Infinity or as proposed to be
engaged in by Infinity before the Effective Time (the "Infinity Business");
(ii) being or becoming an officer, director, stockholder, owner, partner,
employee, manager, salesman, representative, agent or consultant of or to, or
participating in the ownership, management, operation, control or financing
of, any entity that engages or plans or proposes to engage in any business
competitive with the Infinity Business; or (iii) marketing or selling, in any
manner other than in furtherance of the business and interests of SunGard or
other subsidiaries of SunGard engaged in the Infinity Business, any software
competitive with Infinity's software. In addition, the Noncompetition
Agreements restrict the Noncompete Employees from taking the following actions
during the Restriction Period: (i) soliciting employees of SunGard or any
subsidiary of SunGard to leave his or her employment with such companies; or
(ii) interfering or attempting to interfere with the relationship or the
commercial relationship of SunGard or any subsidiary of SunGard with any
person or entity that is or was expected to become a customer or client of
SunGard or any subsidiary thereof.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion summarizes the material federal income tax
considerations of the Merger that are generally applicable to holders of
Infinity Common Stock. This discussion is based on currently existing
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
existing and proposed Treasury Regulations thereunder and current
administrative rulings and court decisions, all of which are subject to
change. Any such change, which may or may not be retroactive, could alter the
tax consequences to SunGard, Infinity or Infinity stockholders as described
herein.
 
  Infinity stockholders should be aware that this discussion does not deal
with all U.S. federal income tax considerations that may be relevant to
particular Infinity stockholders in light of their particular circumstances,
such as stockholders who are dealers in securities, who are subject to the
alternative minimum tax provisions of the Code, who are foreign persons, who
acquired their shares in connection with stock option or stock purchase plans
or in other compensatory transactions or who hold their shares as a hedge or
as part of a hedging, straddle or other risk reduction strategy. In addition,
the following discussion does not address the tax consequences of the Merger
under foreign, state or local tax laws or the tax consequences of transactions
effectuated prior to or after the Merger (whether or not such transactions are
in connection with the Merger).
 
  INFINITY STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE,
LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER IN THEIR PARTICULAR
CIRCUMSTANCES.
 
  Neither SunGard nor Infinity has requested a ruling from the Internal
Revenue Service (the "IRS") with regard to any of the U.S. federal income tax
consequences of the Merger. Morrison & Foerster LLP, counsel to Infinity, and
Cooley Godward LLP, counsel to SunGard, have each rendered an opinion
(collectively, the "Tax Opinions") that the Merger will constitute a
reorganization under Section 368(a) of the Code (a "Reorganization"). As a
condition to the consummation of the Merger, such counsel must also render tax
opinions at the Closing that the Merger will constitute a Reorganization. Such
opinions are, and will be, based on certain assumptions as well as
representations received from SunGard, Infinity and certain stockholders of
Infinity (including an assumption, based on representations, concerning the
"continuity of interest" requirement discussed below) and are, and will be,
subject to the limitations discussed below. Moreover, such opinions will not
be binding on the IRS nor preclude the IRS from adopting a contrary position.
The discussion below assumes that the Merger will qualify as a Reorganization,
based upon such opinions.
 
 
                                      33
<PAGE>
 
  Subject to the limitations and qualifications referred to herein, and as a
result of the Merger's qualifying as a Reorganization, the following U.S.
federal income tax consequences should result:
 
    (i) No gain or loss will be recognized by the holders of Infinity Common
  Stock upon the receipt of SunGard Common Stock solely in exchange for such
  Infinity Common Stock in the Merger (except in respect of cash received in
  lieu of fractional shares of SunGard Common Stock, as discussed below);
 
    (ii) The aggregate tax basis of the SunGard Common Stock so received by
  Infinity stockholders in the Merger (including any fractional share of
  SunGard Common Stock deemed to be received and then redeemed, as discussed
  below) will be the same as the aggregate tax basis of Infinity Common Stock
  surrendered in exchange therefor;
 
    (iii) The holding period of the SunGard Common Stock so received by each
  Infinity stockholder in the Merger will include the period for which the
  Infinity Common Stock surrendered in exchange therefor was considered to be
  held, provided that the Infinity Common Stock so surrendered is held as a
  capital asset at the Effective Time;
 
    (iv) Cash payments received by holders of Infinity Common Stock in lieu
  of a fractional share will be treated as if such fractional share of
  SunGard Common Stock had been issued in the Merger and then redeemed by
  SunGard. An Infinity stockholder receiving such cash will generally
  recognize gain or loss upon such payment, measured by the difference (if
  any) between the amount of cash received and the basis in such fractional
  share. The gain or loss should be capital gain or loss provided that such
  share of Infinity Common Stock was held as a capital asset at the Effective
  Time; and
 
    (v) Neither SunGard nor Infinity will recognize a gain solely as a result
  of the Merger.
 
  The Tax Opinions are subject to certain assumptions and qualifications and
are based on the truth and accuracy of certain representations of SunGard,
Infinity and certain stockholders of Infinity, including representations in
certain certificates delivered to counsel by the respective managements of
SunGard and Infinity and certain stockholders of Infinity. Of particular
importance are the assumptions and representations relating to the "continuity
of interest" requirement.
 
  To satisfy the "continuity of interest" requirement, Infinity stockholders
must not, pursuant to a plan or intent existing at or prior to the Effective
Time, dispose of or transfer so much of either (i) their Infinity Common Stock
in anticipation of the Merger or (ii) the SunGard Common Stock to be received
in the Merger (collectively, "Planned Dispositions"), such that the Infinity
stockholders, as a group, would no longer have a significant equity interest
in the Infinity business being conducted by SunGard after the Merger. Infinity
stockholders will generally be regarded as having a significant equity
interest as long as the SunGard Common Stock received in the Merger (after
taking into account Planned Dispositions), in the aggregate, represents a
substantial portion of the entire consideration received by the Infinity
stockholders in the Merger. No assurance can be made that the "continuity of
interest" requirement will be satisfied, and if such requirement is not
satisfied, the Merger would not be treated as a Reorganization.
 
  A successful IRS challenge to the Reorganization status of the Merger (as a
result of a failure of the "continuity of interest" requirement or otherwise)
would result in significant adverse tax consequences to the Infinity
stockholders. An Infinity stockholder would recognize gain or loss with
respect to each share of Infinity Common Stock surrendered equal to the
difference between the stockholder's basis in such share and the sum of the
fair market value, as of the Effective Time, of the SunGard Common Stock
received in exchange therefor and cash received in lieu of the SunGard Common
Stock. In such event, a stockholder's aggregate basis in the SunGard Common
Stock so received would equal its fair market value, and the stockholder's
holding period for such stock would begin the day after the Closing Date.
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger is intended to be accounted for as a pooling of interests for
financial reporting purposes in accordance with generally accepted accounting
principles. SunGard's obligation to consummate the Merger is conditioned upon
receipt of: (a) a letter from Ernst & Young LLP, dated as of the Closing Date
and addressed to Infinity, reasonably satisfactory in form and substance to
SunGard and Coopers & Lybrand LLP, regarding Ernst & Young LLP's concurrence
with Infinity management's conclusion that no conditions exist related to
Infinity
 
                                      34
<PAGE>
 
that would preclude SunGard from accounting for the Merger as a pooling of
interests; and (b) a letter from Coopers & Lybrand LLP, dated as of the
Closing Date and addressed to SunGard, reasonably satisfactory in form and
substance to SunGard, to the effect that Coopers & Lybrand LLP concurs with
SunGard management's conclusion that SunGard may account for the Merger as a
pooling of interests. SunGard has the right to waive the condition that the
Merger be accounted for as a pooling of interests. If the Merger is
consummated but fails to qualify for pooling of interests accounting
treatment, then the transaction would be accounted for as a purchase.
Accounting for the Merger as a purchase would require SunGard to record
significant intangible assets in connection with the acquisition and to record
significant charges against results of operations, which could materially and
adversely affect SunGard's future results of operations.
 
REGULATORY MATTERS
 
  Under the HSR Act and the rules promulgated thereunder by the FTC, the
Merger may not be consummated until notifications have been given and certain
information has been furnished to the FTC and the Antitrust Division and
specified waiting period requirements have been satisfied or early termination
of the waiting period is granted at the request of SunGard and Infinity.
SunGard and Infinity filed notification and report forms under the HSR Act
with the FTC and the Antitrust Division on November 3, 1997. These filings
commenced a 30-day waiting period under the HSR Act. If, prior to the
expiration of such period, the FTC or the Antitrust Division should request
additional information or documentary material under the HSR Act, consummation
of the Merger could be delayed until after the companies have substantially
complied with the request. There can be no assurance that a challenge to the
Merger on antitrust grounds will not be made, or if such challenge is made,
that SunGard and Infinity would prevail or would not be required to terminate
the Reorganization Agreement, to divest certain assets, to license certain
proprietary technology to third parties or to accept certain conditions in
order to consummate the Merger. SunGard does not have any obligation under the
Reorganization Agreement to: (i) dispose or cause any of its subsidiaries to
dispose of any assets; (ii) discontinue or make any changes to its operations
or proposed operations or to the operations or proposed operations of any of
its subsidiaries; or (iii) make any commitment (to any governmental body or
otherwise) regarding its future operations, or the future operations of its
subsidiaries, or the future operations of Infinity or its subsidiaries, even
though the disposition of such assets or the making of such change or
commitment might facilitate the obtaining of a required governmental
authorization or might otherwise facilitate the consummation of the Merger.
 
ABSENCE OF APPRAISAL RIGHTS
 
  Under Section 262 of the DGCL, stockholders who do not vote in favor of or
consent to a merger are not entitled to appraisal rights if the stock subject
to such merger is designated as a national market system security on an
interdealer quotation system by the National Association of Securities
Dealers, Inc. and the consideration to be received in such merger consists of
stock listed on a national securities exchange. Because the Nasdaq National
Market is designated as such a system and the Infinity Common Stock is quoted
on the Nasdaq National Market, and because the NYSE is a national securities
exchange and the SunGard Common Stock is listed on the NYSE, Infinity
stockholders are not entitled to appraisal rights with respect to the Merger.
 
RESALE OF SUNGARD COMMON STOCK
 
  The SunGard Common Stock issued in connection with the Merger will be freely
transferable, except that shares issued to any Infinity stockholder who is an
Affiliate of Infinity or who becomes an Affiliate of SunGard are subject to
certain restrictions on resale. An Affiliate is defined generally as
including, without limitation, directors, certain executive officers and
certain other persons who control a company. Certain stockholders of Infinity
who may be deemed to be Affiliates have executed agreements that prohibit the
sale, transfer or other disposition of SunGard Common Stock received by such
stockholders in the Merger, except under certain circumstances, in order to
comply with the requirements of certain federal securities laws and certain
pooling of interests requirements. See "Approval of the Merger and Related
Transactions--Affiliate Agreements." Certain stockholders have also delivered
to SunGard certificates certifying that such stockholders have no present
intention to dispose of certain of the shares of SunGard Common Stock to be
received by such stockholders in the Merger in order to comply with the
requirements of certain U.S. federal tax laws. See "Approval of the Merger and
Related Transactions--Certain Federal Income Tax Consequences."

                         THE REORGANIZATION AGREEMENT
 
GENERAL
 
  The following is a summary of the material provisions of the Reorganization
Agreement, a copy of which is attached as Appendix A to this Proxy
Statement/Prospectus and is incorporated herein by reference. However, the
following is not a complete statement of all provisions of the Reorganization
Agreement and related agreements. Statements made in this Proxy
Statement/Prospectus with respect to the terms of the Reorganization Agreement
and such related agreements are qualified in their respective entireties by
reference to the more detailed information set forth in the Reorganization
Agreement and such related agreements.
 
  The Reorganization Agreement provides for the merger of Merger Sub with and
into Infinity. As a result of the Merger, Merger Sub will cease to exist,
Infinity will become a wholly owned subsidiary of SunGard and the former
stockholders of Infinity will become stockholders of SunGard. Infinity will
continue as the surviving corporation of the Merger (the "Surviving
Corporation") and will retain all of its separate corporate existence, with
all its purposes, objects, rights, privileges, powers and franchises
unaffected by the Merger. Merger Sub has been formed solely for the purpose of
effecting the Merger, and there will be no other activity in Merger Sub. The
Merger will become effective upon the filing of a Certificate of Merger with
the Delaware Secretary of State or at such later time as may be specified in
the Certificate of Merger. Such filing is anticipated to take place as soon as
practicable after the adoption and approval of the Reorganization Agreement
and approval of the Merger by the Infinity stockholders and after expiration
or termination of the waiting period under the HSR Act, subject to the
satisfaction or waiver of the other conditions to the Merger. It is currently
anticipated that the Merger will be consummated, and the Effective Time will
occur, in       1997. There can be no assurance, however, that the conditions
to the Merger will be satisfied by such date, or at all, or that the
Reorganization Agreement will not be terminated. See "--Conditions to the
Merger" and "Approval of the Merger and Related Transactions--Regulatory
Matters."
 
MERGER CONSIDERATION
 
  Infinity Common Stock. Subject to the provisions contained in the
Reorganization Agreement relating to the payment of cash in lieu of fractional
shares, at the Effective Time, each share of Infinity Common Stock then
outstanding (except for any such shares held by Infinity as treasury stock and
any shares held by SunGard or any subsidiary of SunGard or Infinity) will be
converted into the right to receive SunGard Common Stock based on the Exchange
Ratio.
 
  No Fractional Shares. No fractional shares of SunGard Common Stock will be
issued in connection with the Merger, and no certificates for any such
fractional shares will be issued. In lieu of such fractional shares, any
holder of Infinity Common Stock who would otherwise be entitled to receive a
fraction of a share of SunGard Common Stock (after aggregating all fractional
shares of SunGard Common Stock issuable to such holder) will, upon surrender
of such holder's stock certificate(s) representing Infinity Common Stock to
the Exchange Agent, be paid in cash the dollar amount (rounded to the nearest
whole cent), without interest, determined by multiplying such fraction by the
closing price of a share of SunGard Common Stock on the NYSE on the date the
Merger becomes effective.
 
STOCK OPTIONS; EMPLOYEE STOCK PURCHASE PLAN
 
  Stock Options. At the Effective Time, all rights with respect to Infinity
Common Stock under each Infinity Option then outstanding shall be converted
into and become rights with respect to SunGard Common Stock, and SunGard shall
assume each such Infinity Option in accordance with the terms (as in effect as
of October 17, 1997) of the stock option plan under which it was issued and
the stock option agreement by which it is evidenced. From and after the
Effective Time, (i) each Infinity Option assumed by SunGard may be exercised
solely for shares of SunGard Common Stock, (ii) the number of shares of
SunGard Common Stock subject to each such Infinity Option shall be equal to
the number of shares of Infinity Common Stock subject to such Infinity Option
 
                                      36
<PAGE>
 
immediately prior to the Effective Time multiplied by the Exchange Ratio,
rounded down to the nearest whole share (with cash, less the applicable
exercise price, being payable for any fraction of a share), (iii) the per
share exercise price under each such Infinity Option shall be adjusted by
dividing the per share exercise price under such Infinity Option by the
Exchange Ratio and rounding up to the nearest cent, and (iv) any restriction
on the exercise of any such Infinity Option shall continue in full force and
effect and the term, exercisability, vesting schedule and other provisions of
such Infinity Option shall otherwise remain unchanged (subject to adjustment
as appropriate to reflect any stock split, stock dividend, reverse stock
split, reclassification, recapitalization or other similar transaction
subsequent to the Effective Time). SunGard has agreed to file with the
Commission a Registration Statement on Form S-8 relating to the shares of
SunGard Common Stock issuable with respect to assumed Infinity Options no
later than 30 days after the Effective Time.
 
  Employee Stock Purchase Plan. The Infinity Purchase Plan will be terminated
as of the Effective Time. The rights of participants in the Infinity Purchase
Plan with respect to any offering period then underway under the Infinity
Purchase Plan shall be determined by treating the last business day prior to
the Effective Time as the last day of such offering period and by making such
other pro rata adjustments as may be necessary to reflect the reduced offering
period but otherwise treating such offering period as a fully effective and
completed offering period for all purposes of the Infinity Purchase Plan.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
  Based upon the number of shares of Infinity Common Stock issued and
outstanding as of the Record Date, an aggregate of approximately     shares of
SunGard Common Stock will be issued to holders of Infinity Common Stock. Based
upon the number of shares of SunGard Common Stock issued and outstanding as of
the Record Date, and after giving effect to the additional shares of SunGard
Common Stock that are proposed to be issued in the Merger (and assuming no
exercise of outstanding options to purchase SunGard Common Stock or Infinity
Common Stock), the former holders of Infinity Common Stock would hold
approximately  % of SunGard's total issued and outstanding shares.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES.
 
  As soon as reasonably practicable after the Effective Time, the Exchange
Agent will mail to the registered holders of Infinity Common Stock (i) the
Letter of Transmittal and (ii) instructions for use of the Letter of
Transmittal in effecting the surrender of Infinity Stock Certificates in
exchange for certificates representing SunGard Common Stock. Upon surrender of
an Infinity Stock Certificate to the Exchange Agent for exchange, together
with a duly executed Letter of Transmittal and such other documents as may be
reasonably required by the Exchange Agent or SunGard, the holder of such
Infinity Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the whole number of shares of SunGard Common Stock
that such holder has the right to receive. No fractional shares of SunGard
Common Stock will be issued in connection with the Merger, and no certificates
for any such fractional shares will be issued. See "-No Fractional Shares."
 
  If any Infinity Stock Certificate has been lost, stolen or destroyed,
SunGard may require the owner of such lost, stolen or destroyed Infinity Stock
Certificate to provide an appropriate affidavit and to deliver a bond (in such
sum as SunGard may reasonably direct) as indemnity against any claim that may
be made against the Exchange Agent, SunGard or Infinity with respect to such
Infinity Stock Certificate.
 
  INFINITY STOCKHOLDERS SHOULD NOT SURRENDER THEIR INFINITY STOCK CERTIFICATES
FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL.
 
EFFECT ON CERTIFICATES
 
  At the Effective Time, (i) all shares of Infinity Common Stock outstanding
immediately prior to the Effective Time will automatically be canceled and
retired and will cease to exist, and all holders of certificates representing
shares of Infinity Common Stock that were outstanding immediately prior to the
Effective Time
 
                                      37
<PAGE>
 
will cease to have any rights as stockholders of Infinity, and (ii) the stock
transfer books of Infinity will be closed with respect to all shares of
Infinity Common Stock outstanding immediately prior to the Effective Time. No
further transfer of any such shares of Infinity Common Stock will be made on
such stock transfer books after the Effective Time. If, after the Effective
Time, an Infinity Stock Certificate is presented to the Exchange Agent (or to
Infinity or SunGard), such Infinity Stock Certificate will be canceled and
will be exchanged as provided above under the caption "--Conversion of Shares;
Procedure for Exchange of Certificates; No Fractional Shares."
 
CORPORATE MATTERS
 
  As of the Effective Time, the Certificate of Incorporation of the Surviving
Corporation will be amended and restated to conform to the form of certificate
of incorporation attached to the Reorganization Agreement, and the Bylaws of
the Surviving Corporation will be amended and restated to conform to the
Bylaws of Merger Sub as in effect immediately prior to the Effective Time. The
Reorganization Agreement provides that concurrently with the Effective Time,
the directors and officers of Infinity will resign and the directors and
officers of the Surviving Corporation immediately after the Effective Time
shall be the respective individuals who are directors and officers of Merger
Sub immediately prior to the Effective Time.

  on the Acquired Corporations.
 
  Additional Covenants of the Parties. The Reorganization Agreement also
contains certain additional covenants of the parties including covenants
relating to: (i) the preparation and filing of the Registration Statement;

plans; (v) indemnification of officers and directors; (vi) actions regarding
pooling of interests accounting for the Merger; (vii) the preparation and

  Infinity has agreed in the Reorganization Agreement (i) to take all action
necessary in accordance with all applicable law to call, give notice of,
convene and hold the Infinity Special Meeting, and (ii) not to withdraw, amend
or modify, or propose or resolve to withdraw, amend or modify, in a manner
adverse to SunGard, the unanimous recommendation of the Infinity Board of
Directors that the Infinity stockholders vote in favor of and adopt and
approve the Reorganization Agreement and approve the Merger; provided,
however, that nothing in the Reorganization Agreement will prevent the
Infinity Board of Directors from withdrawing, amending or modifying its
recommendation in favor of the Merger if (a) a "Superior Offer" (as defined
below) is made to Infinity and is not withdrawn, (b) neither Infinity nor any
of its Representatives shall have violated certain covenants, including the
covenants not to solicit, initiate, encourage or induce the making of an
Acquisition Proposal, and (c) the Infinity Board of Directors concludes in
good faith, based upon the advice of its outside counsel, in light of the
Superior Offer, that the withdrawal, amendment or modification of such
recommendation is required in order for it to comply with its fiduciary
obligations to Infinity's stockholders under applicable law.
 
                                      40
<PAGE>
 
The Reorganization Agreement provides that nothing contained in the
Reorganization Agreement shall limit Infinity's obligation to call, give
notice of, convene and hold the Infinity Special Meeting (regardless of
whether the unanimous recommendation of the Infinity Board of Directors shall
have been withdrawn, amended or modified).
 
  A "Superior Offer" is defined as an unsolicited, bona fide written offer
made by a third party to purchase more than 50% of the outstanding shares of
Infinity Common Stock on terms that the Infinity Board of Directors
determines, in its reasonable judgment, based upon the written advice of its
financial advisor, to be more favorable from a financial point of view to
Infinity's stockholders than the terms of the Merger; provided, however, that
any such offer shall not be deemed to be a "Superior Offer" if any financing
required to consummate the transaction contemplated by such offer is not
committed and is not likely to be obtained by such third party on a timely
basis.
 
  Pursuant to the Reorganization Agreement, SunGard and Infinity have agreed
to use all reasonable efforts to take, or cause to be taken, all actions
necessary to consummate the Merger and make effective the other transactions
contemplated by the Reorganization Agreement; however, SunGard does not have
any obligation under the Reorganization Agreement to: (i) dispose or cause any
of its subsidiaries to dispose of any assets, or commit to cause any of the
Acquired Corporations to dispose of any assets; (ii) discontinue or cause any
of its subsidiaries to discontinue offering any product, or commit to cause
any of the Acquired Corporations to discontinue offering any product; (iii)
license or otherwise make available, or cause any of its subsidiaries to
license or otherwise make available, to any third party, any technology,
software or other proprietary asset, or commit to cause any of the Acquired
Corporations to license or otherwise make available to any third party any
technology, software or other proprietary asset; (iv) hold separate or cause
any of its subsidiaries to hold separate any assets or operations, or to
commit to cause any of the Acquired Corporations to hold separate any assets
or operations; or (v) make or cause any of its subsidiaries to make any
commitment regarding its future operations or the future operations of any of
the Acquired Corporations.
 
NON-SOLICITATION
 
  Pursuant to the Reorganization Agreement, Infinity has agreed that it will
not, directly or indirectly, and will not authorize or permit any of the other
Acquired Corporations or any Representative of any of the Acquired
Corporations, directly or indirectly to (i) solicit, initiate, encourage or
induce the making, submission or announcement of any Acquisition Proposal or
take any action that could reasonably be expected to lead to an Acquisition
Proposal, (ii) furnish any information regarding any of the Acquired
Corporations to any third party in connection with or in response to an
Acquisition Proposal, (iii) engage in discussions or negotiations with any
third party with respect to any Acquisition Proposal, (iv) approve, endorse or
recommend any Acquisition Proposal or (v) enter into any letter of intent or
similar document or any contract or other agreement contemplating or otherwise
relating to any Acquisition Transaction; provided, however, that: (A) such
provisions shall not prohibit the Infinity Board of Directors from disclosing
to Infinity's stockholders a position with respect to a tender offer pursuant
to Rules 14d-9 and 14e-2 promulgated under the Exchange Act; and (B) prior to
the adoption and approval of the Reorganization Agreement by the Required
Vote, such provisions shall not prohibit Infinity from (x) furnishing
nonpublic information regarding the Acquired Corporations to any third party
in response to an Acquisition Proposal that is submitted by such third party
(and not withdrawn), or (y) entering into discussions with any third party in
response to a Superior Offer that is submitted by such third party (and not
withdrawn) if, in either such case, (a) neither Infinity nor any
Representative of any of the Acquired Corporations has violated any of the
restrictions set forth above in this sentence, (b) the Infinity Board of
Directors believes in good faith, based upon the advice of outside legal
counsel, that such action is required in order for the Infinity Board of
Directors to comply with its fiduciary obligations to Infinity's stockholders
under applicable law, (c) prior to furnishing any such nonpublic information
to, or entering into discussions with, such third party, Infinity gives
SunGard written notice of the identity of such third party and of Infinity's
intention to furnish nonpublic information to, or enter into discussions with,
such third party, and Infinity receives from such third party an executed
confidentiality agreement containing limitations on the use and disclosure of
all nonpublic
 
                                      41
<PAGE>
 
written and oral information furnished to such third party by or on behalf of
Infinity, and (d) prior to furnishing any such nonpublic information to such
third party, Infinity furnishes such nonpublic information to SunGard (to the
extent such nonpublic information has not been previously furnished by
Infinity to SunGard). Without limiting the generality of the foregoing,
pursuant to the Reorganization Agreement, Infinity has acknowledged and agreed
that any violation of any of the restrictions referenced in the preceding
sentence by any Representative of any of the Acquired Corporations, whether or
not such Representative is purporting to act on behalf of any of the Acquired
Corporations, shall be deemed to constitute a breach of Infinity's obligations
referenced in the preceding sentence; provided, however, that the limitations
described in the preceding sentence shall not limit the rights of any
Representative who is a stockholder of Infinity to freely vote his stock and
to exercise all of his rights as a stockholder of Infinity, subject to any
contractual restrictions that may apply. In addition, the Reorganization
Agreement requires Infinity to promptly advise SunGard orally and in writing
of any Acquisition Proposal (including the identity of the person making or
submitting such Acquisition Proposal and the terms thereof) that is made or
submitted by any person during the period between the date of the
Reorganization Agreement and until the Effective Time, to keep SunGard fully
informed with respect to the status of any such Acquisition Proposal and any
modification or proposed modification thereto and to immediately cease and
cause to be terminated any existing discussions with any person that relate to
any Acquisition Proposal.
 
INDEMNIFICATION AND INSURANCE
 
  Pursuant to the Reorganization Agreement, all rights to indemnification
existing in favor of the persons serving as directors or officers of Infinity
as of the date of the Reorganization Agreement for acts and omissions
occurring prior to the Effective Time, as provided in Infinity's Bylaws (as in
effect as of the date of the Reorganization Agreement) and as provided in the
indemnification agreements between Infinity and said directors and officers
(as in effect as of the date of the Reorganization Agreement), shall survive
the Merger, and SunGard shall cause the Surviving Corporation to perform all
of its obligations arising thereunder for a period of not less than six years
from the Effective Time. The Reorganization Agreement also provides that from
the Effective Time until the third anniversary of the date on which the
Effective Time occurs, SunGard will cause the Surviving Corporation to
maintain in effect, for the benefit of the persons serving as directors and
officers of Infinity as of the date of the Reorganization Agreement with
respect to acts or omissions occurring prior to the Effective Time, the
existing policy of directors' and officers' liability insurance maintained by
Infinity as of the date of the Reorganization Agreement (the "Existing
Policy"); provided, however, that (i) the Surviving Corporation may substitute
for the Existing Policy a policy or policies of comparable coverage, and (ii)
the Surviving Corporation shall not be required to pay an annual premium for
the Existing Policy (or for any substitute policies) in excess of $225,000.
The Reorganization Agreement further provides that in the event any future
annual premium for the Existing Policy (or any substitute policies) exceeds
$225,000, the Surviving Corporation shall be entitled to reduce the amount of
coverage of the Existing Policy (or any substitute policies) to the amount of
coverage that can be obtained for a premium equal to $225,000.

with respect to the stock of the Surviving Corporation; provided, however,
that: (A) any material adverse effect that results from general economic,

disproportionate manner shall be disregarded in determining whether there has
been a "Material Adverse Effect" on the Acquired Corporations; and (B) any
material adverse effect that results from the taking of any action required by
the Reorganization Agreement or from the announcement or pendency of the
transactions contemplated by the Reorganization Agreement shall be disregarded

  All the conditions to SunGard's and Merger Sub's obligation to effect the
Merger must either be satisfied or be waived prior to the consummation of the
Merger.
 
  Infinity. The obligation of Infinity to effect the Merger and otherwise

conditions:
 
    (i) the representations and warranties of SunGard and Merger Sub
  contained in the Reorganization Agreement shall have been accurate in all
  respects as of the date of the Reorganization Agreement (it being
  understood that, for purposes of determining the accuracy of such
  representations and warranties: (i) any inaccuracies that, in the
  aggregate, do not have a Material Adverse Effect on SunGard shall be
  disregarded; and (ii) all "Material Adverse Effect" qualifications and
  other materiality qualifications contained in such representations and
  warranties shall be disregarded);
 
    (ii) the representations and warranties of SunGard and Merger Sub
  contained in the Reorganization Agreement (except for any representation or
  warranty that refers specifically to the date of the Reorganization
  Agreement or to any specific date or period prior to the date of the
  Reorganization Agreement) shall be accurate in all respects as of the
  Closing Date as if made on and as of the Closing Date (it being understood
  that, for purposes of determining the accuracy of such representations and
  warranties as of the Closing Date: (a) any inaccuracies that, in the
  aggregate, do not have a Material Adverse Effect on SunGard shall be
  disregarded; (b) any inaccuracy that results from general business,
  economic or industry conditions that do not affect SunGard in a
  disproportionate manner shall be disregarded; (c) any inaccuracy that
  results from the taking of any action required by the Reorganization
  Agreement or the announcement or pendency of the transactions contemplated
  by the Reorganization Agreement shall be disregarded; and (d) all "Material
  Adverse Effect" qualifications and other materiality qualifications
  contained in such representations and warranties shall be disregarded);
 
    (iii) all of the covenants and obligations that SunGard and Merger Sub
  are required to comply with or to perform at or prior to the Closing shall
  have been complied with and performed in all material respects;
 
    (iv) the Registration Statement shall have become effective in accordance
  with the provisions of the Securities Act, and no stop order shall have
  been issued by the Commission with respect to the Registration Statement;

    (vi) Infinity shall have received the following documents: (a) subject to
  the receipt and reliance upon by Morrison & Foerster LLP of certain
  Continuity of Interest Certificates and certain tax representation letters,
  a legal opinion of Morrison & Foerster LLP, dated as of the Closing Date,
  to the effect that the Merger will constitute a reorganization within the
  meaning of Section 368 of the Code, and (b) a certificate executed on
  behalf of SunGard by an executive officer of SunGard confirming that the
  conditions set forth in under clause "(i)", "(ii)", "(iii)" and "(vii)" of
  this paragraph have been duly satisfied;
 
                                      45
<PAGE>
 
    (vii) there shall have been no change in SunGard's business, operations
  or financial condition since the date of the Reorganization Agreement which
  has had or would reasonably be expected to have a Material Adverse Effect
  on SunGard (it being understood that a decline in SunGard's stock price
  shall not, in and of itself, constitute a change that has had or would
  reasonably be expected to have a Material Adverse Effect on SunGard for
  purposes of this clause "(vii)");
 
    (viii) the waiting period applicable to the consummation of the Merger
  under the HSR Act shall have expired or been terminated;
 
    (ix) the shares of SunGard Common Stock to be issued in the Merger shall
  have been approved for listing (subject to notice of issuance) on the NYSE;
  and
 
    (x) no temporary restraining order, preliminary or permanent injunction
  or other order preventing the consummation of the Merger by Infinity shall
  have been issued by any court of competent jurisdiction and remain in
  effect, and there shall not be any legal requirement enacted or deemed
  applicable to the Merger that makes consummation of the Merger by Infinity
  illegal.
 
  For purposes of the Reorganization Agreement, an event, violation, change,
failure, inaccuracy, circumstance or other matter will be deemed to have a
Material Adverse Effect on SunGard if such event, violation, change, failure,
inaccuracy, circumstance or other matter (considered together with all other
matters that would constitute exceptions to the representations and warranties
of SunGard and Merger Sub in the Reorganization Agreement but for the presence
of "Material Adverse Effect" or other materiality qualifications, or any
similar qualifications, in such representations and warranties) would have a
material adverse effect on the business, operations or financial condition of
SunGard and its subsidiaries taken as a whole; provided, however, that: (a)
any material adverse effect that results from general economic, business or
industry conditions that do not affect SunGard in a disproportionate manner
shall be disregarded in determining whether there has been a "Material Adverse
Effect" on SunGard; (b) any material adverse effect that results from the
taking of any action required by the Reorganization Agreement or from the
announcement or pendency of the transactions contemplated by the
Reorganization Agreement shall be disregarded in determining whether there has
been a "Material Adverse Effect" on SunGard; and (c) a decline in SunGard's
stock price shall not, in and of itself, constitute a "Material Adverse
Effect" on SunGard and shall be disregarded in determining whether there has
been a "Material Adverse Effect" on SunGard.
 
  All the conditions to Infinity's obligation to effect the Merger must either
be satisfied or be waived prior to the consummation of the Merger.
 
TERMINATION
 
  The Reorganization Agreement may be terminated prior to the Effective Time,
whether before or after approval of the Merger by the stockholders of
Infinity:
 
    (i) by mutual written consent of SunGard and Infinity;
 
    (ii) by either SunGard or Infinity if the Merger shall not have been
  consummated by March 31, 1998 (unless the failure to consummate the Merger
  is attributable to a failure on the part of the party seeking to terminate
  the Reorganization Agreement to perform any material obligation required to
  be performed by such party at or prior to the Effective Time);
 
    (iii) by either SunGard or Infinity if a court of competent jurisdiction
  or other governmental body shall have issued a final and nonappealable
  order, decree or ruling, or shall have taken any other action, having the
  effect of permanently restraining, enjoining or otherwise prohibiting the
  Merger;
 
    (iv) by SunGard, following a breach of any covenant or agreement of
  Infinity contained in the Reorganization Agreement, or if any
  representation or warranty of Infinity contained in the Reorganization
  Agreement shall be or shall have become inaccurate, in either case such
  that any of the conditions set forth in clauses "(i)," "(ii)," "(iii)," and
  "(iv)" under "-Conditions to the Merger--SunGard and Merger Sub" would not
  be satisfied as of the time of such breach or as of the time such
  representation or warranty was or
 
                                      46
<PAGE>
 
  shall have become inaccurate; provided, however, that: (a) if such breach
  or inaccuracy is curable by Infinity, then SunGard may not terminate the
  Reorganization Agreement under the circumstances described in this clause
  "(iv)" with respect to a particular breach or inaccuracy prior to or during
  the 30-day period commencing upon delivery by SunGard of written notice to
  Infinity of such breach or inaccuracy, provided Infinity continues to
  exercise reasonable efforts to cure such breach or inaccuracy; and (b) the
  right to terminate the Reorganization Agreement under the circumstances
  described in this clause "(iv)" shall not be available to SunGard if
  SunGard shall have committed a material uncured breach of the
  Reorganization Agreement;
 
    (v) by Infinity, following a breach of any covenant or agreement of
  SunGard contained in the Reorganization Agreement, or if any representation
  or warranty of SunGard contained in the Reorganization Agreement shall be
  or shall have become inaccurate, in either case such that any of the
  conditions set forth in clauses "(i)," "(ii)" and "(iii)" under "-
  Conditions to the Merger -Infinity" would not be satisfied as of the time
  of such breach or as of the time such representation or warranty was or
  shall have become inaccurate; provided, however, that: (a) if such breach
  or inaccuracy is curable by SunGard, then Infinity may not terminate the
  Reorganization Agreement under the circumstances described in this clause
  "(v)" with respect to a particular breach or inaccuracy prior to or during
  the 30-day period commencing upon delivery by Infinity of written notice to
  SunGard of such breach or inaccuracy, provided SunGard continues to
  exercise reasonable efforts to cure such breach or inaccuracy; and (b) the
  right to terminate the Reorganization Agreement under the circumstances
  described in this clause "(v)" shall not be available to Infinity if
  Infinity shall have committed a material uncured breach of the
  Reorganization Agreement;
 
    (vi) by SunGard, if: (a) the Infinity Board of Directors shall for any
  reason have withdrawn or shall have amended or modified in a manner adverse
  to SunGard its unanimous recommendation in favor of the adoption and
  approval of the Reorganization Agreement or the approval of the Merger; (b)
  Infinity shall have entered into any letter of intent or similar document
  or any contract relating to any Acquisition Proposal; or (c) a tender or
  exchange offer relating to securities of Infinity shall have been commenced
  and Infinity shall not have sent to its securityholders, within ten
  business days after the commencement of such tender or exchange offer, a
  statement disclosing that Infinity recommends rejection of such tender or
  exchange offer; or
 
    (vii) by either SunGard or Infinity if (a) the Infinity Special Meeting
  shall have been held and (b) the Reorganization Agreement and the Merger
  shall not have been adopted and approved at such meeting by the Required
  Vote.
 
EXPENSES AND TERMINATION FEE
 
  Pursuant to the Reorganization Agreement, all fees and expenses incurred in
connection with the Reorganization Agreement and the transactions contemplated
by the Reorganization Agreement shall be paid by the party incurring such
expenses, whether or not the Merger is consummated; provided, however, that
SunGard and Infinity shall share equally all fees and expenses, other than
attorneys' fees, incurred in connection with the filing, printing and mailing
of the Registration Statement and the Proxy Statement/Prospectus and any
amendments or supplements thereto and the filing of the premerger notification
and report forms relating to the Merger under the HSR Act.
 
  The Reorganization Agreement provides that if it is terminated by SunGard
pursuant to the termination provisions described in clause (vi) under
"Termination," then Infinity shall pay to SunGard, in cash, within one
business day after the termination of the Reorganization Agreement, a
nonrefundable fee in the amount of $9,500,000. The Reorganization Agreement
further provides that if (a) it is terminated by SunGard or Infinity because
the Infinity Special Meeting shall have been held and the Reorganization
Agreement and the Merger shall not have been approved at such meeting by the
Required Vote, (b) at or prior to the time of the termination of the
Reorganization Agreement, an Acquisition Proposal shall have been submitted,
announced or made, and (c) an Acquisition Transaction is consummated on or
prior to the date that is 270 days following the date of such termination,
then, contemporaneously with the consummation of such Acquisition Transaction
(and regardless of
 
                                      47
<PAGE>
 
whether such Acquisition Transaction involves the person or persons that
submitted, announced or made the Acquisition Proposal referred to in clause
"(b)" of this sentence), Infinity shall pay to SunGard, in cash, a
nonrefundable fee in the amount of $9,500,000.
 
AMENDMENT; WAIVER
 
  The Reorganization Agreement provides that: (a) the Reorganization Agreement
may be amended with the approval of the respective Boards of Directors of
Infinity and SunGard at any time before or after adoption and approval of the
Reorganization Agreement by the stockholders of Infinity; provided, however,
that after any such adoption and approval of the Reorganization Agreement and
the Merger by Infinity's stockholders, no amendment shall be made which by law
requires further approval of the stockholders of Infinity without the further
approval of such stockholders; (b) the Reorganization Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties thereto; (c) no failure on the part of any party to the Reorganization
Agreement to exercise any power, right, privilege or remedy under the
Reorganization Agreement, and no delay on the part of any party to the
Reorganization Agreement in exercising any power, right, privilege or remedy
under the Reorganization Agreement, shall operate as a waiver of such power,
right, privilege or remedy; and no single or partial exercise of any such
power, right, privilege or remedy shall preclude any other or further exercise
thereof or of any other power, right, privilege or remedy; and (c) no waiver
under the Reorganization Agreement will be effective unless it is expressly
set forth in a written instrument duly executed and delivered on behalf of the
party against whom the enforcement of such waiver is being sought.

NOTE 1--STOCK SPLIT
 
  The number of fully diluted shares used to calculate net income per common
share has been adjusted retroactively to reflect two-for-one stock splits
which occurred in July 1995 and September 1997.
 
NOTE 2--EXCHANGE RATIO
 
  Under the Reorganization Agreement, subject to the provisions contained
therein relating to the payment of cash in lieu of fractional shares, each
outstanding share of Infinity Common Stock will be converted into the right to
receive 0.68 of a share of SunGard Common Stock (subject to adjustment as
appropriate to reflect any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction involving the
SunGard Common Stock or the Infinity Common Stock between the date of the
Reorganization Agreement and the effective time of the Merger). Also, all
options to purchase shares of Infinity Common Stock will be converted into
options to purchase shares of SunGard Common Stock (subject to appropriate
adjustments to the exercise price and number of shares subject thereto based
upon the foregoing exchange ratio). This exchange ratio was used in computing
shares and per share amounts in the accompanying unaudited pro forma combined
condensed financial statements.
 
NOTE 3--MERGER COSTS
 
  All pro forma information excludes merger costs, estimated to be
approximately $4.0 million. These costs are principally comprised of
investment advisory, legal, accounting and printing costs and will be charged
to expense in the period the Merger is consummated.

DESCRIPTION OF INFINITY CAPITAL STOCK
 
  The authorized capital stock of Infinity consists of 50,000,000 shares of
Infinity Common Stock, and 5,000,000 shares of Preferred Stock, $0.001 par
value ("Infinity Preferred Stock").
 
  Infinity Common Stock. As of the Record Date, there were approximately
shares of Infinity Common Stock outstanding held of record by approximately
    stockholders. The holders of Infinity Common Stock are entitled to one
vote per share on all matters to be voted upon by the stockholders. The
holders of Infinity Common Stock are entitled to receive ratably such
dividends if any, as may be declared from time to time by the Infinity Board
of Directors out of funds legally available therefor. In the event of the
liquidation, dissolution or winding up of Infinity, the holders of Infinity
Common Stock are entitled to share ratably in all assets remaining after
payment of liabilities subject to prior distribution rights of Infinity
Preferred Stock, if any, then outstanding. The Infinity Common Stock has no
preemptive or conversion rights or other subscription rights. All outstanding
shares of Infinity Common Stock are fully paid and nonassessable.
 
  Infinity Preferred Stock. Infinity has 5,000,000 shares of Infinity
Preferred Stock authorized, of which no shares are outstanding. The Infinity
Board of Directors has the authority to issue up to 5,000,000 shares of
Infinity Preferred Stock, in one or more series and to fix the rights,
preferences, privileges and restrictions granted
 
                                      57

to or imposed upon any unissued and undesignated shares of Infinity Preferred
Stock and to fix the number of shares constituting any series and the
designations of such series, without any further vote or action by the
stockholders. Although it presently has no intention to do so, the Infinity
Board of Directors, without stockholder approval, can issue Infinity Preferred
Stock with voting and conversion rights which could adversely affect the
voting power or other rights of the holders of Infinity Common Stock. The
issuance of Infinity Preferred Stock may have the effect of delaying,
deferring or preventing a change in control of Infinity.
 
  Infinity Transfer Agent and Registrar. The Transfer Agent and Registrar for
the Infinity Common Stock is Boston EquiServe and its telephone number is
(617) 575-3120.
 
                  COMPARISON OF RIGHTS OF HOLDERS OF SUNGARD
               COMMON STOCK AND HOLDERS OF INFINITY COMMON STOCK
 
  Upon consummation of the Merger, the holders of Infinity Common Stock will
become holders of SunGard Common Stock. There are certain material differences
between the rights and privileges of the holders of Infinity Common Stock and
the holders of SunGard Common Stock.
 
  Percentage of Voting Stock; Influence Over Affairs. Upon completion of the
Merger, the percentage ownership of SunGard by each former Infinity
stockholder will be substantially less than such stockholder's current
percentage ownership of Infinity. Accordingly, former Infinity stockholders
will have a significantly smaller voting influence over the affairs of SunGard
than they currently enjoy over the affairs of Infinity.
 
  Cumulative Voting. In an election of directors under cumulative voting, each
share of stock normally having one vote is entitled to the number of votes
equal to the number of directors to be elected. A stockholder may cast all
such votes for a single candidate or may allocate them among as many
candidates as the stockholder may choose. Under Delaware law, cumulative
voting in the election of directors is not available unless specifically
provided for in the certificate of incorporation. The Certificate of
Incorporation, as amended, of Infinity provides for cumulative voting, whereas
the Restated Certificate of Incorporation of SunGard does not provide for
cumulative voting and cumulative voting is therefore not available to the
SunGard Stockholders.
 
  Power to Call Special Stockholders' Meetings. According to the Bylaws, as
amended, of Infinity, a special meeting of the Infinity stockholders may be
called only by the Chairman of the Board, the President or the Board of
Directors of Infinity. The Amended and Restated Bylaws of SunGard also provide
that special meetings of the SunGard stockholders may be called by the
Chairman of the Board, the President or the SunGard Board of Directors, but
further provide that such meetings shall be called by the Chairman of the
Board, the President or the SunGard Board of Directors if so requested in
writing by the SunGard stockholders holding of record at least 50% of the
outstanding shares of stock entitled to vote at such a meeting.
 
  Stock Exchange Rules. The Infinity Common Stock is currently listed on the
Nasdaq National Market and will cease to trade on the Nasdaq National Market
upon consummation of the Merger. The SunGard Common Stock is traded on the
NYSE. There are material differences between the corporate governance rules of
the Nasdaq National Market and the NYSE.

     Merger Sub or any other subsidiary of Parent shall be canceled and retired
     and shall cease to exist, and no consideration shall be delivered in
     exchange therefor;

               (iii)  except as provided in clauses "(i)" and "(ii)" above and
     subject to Sections 1.5(b) and 1.5(c), each share of Company Common Stock
     then outstanding shall be converted into the right to receive sixty-eight
     hundredths (0.68) of a share of Parent Common Stock;

               (iv) the Company's 1989 Stock Option Plan, the Company's 1993
     Stock Incentive Plan and the Company's 1996 Stock Incentive Plan
     (collectively, the "Company Stock Option Plans") and all options to
     purchase Company Common Stock then outstanding under the Company Stock
     Option Plans shall be assumed by Parent in accordance with Section 5.4; and

               (v) each share of the common stock, $.01 par value per share, of
     Merger Sub then outstanding shall be converted into one share of common
     stock of the Surviving Corporation.

          (b) The fraction of a share of Parent Common Stock specified in
Section 1.5(a)(iii) (as such fraction may be adjusted in accordance with this
Section 1.5(b)) is referred to as the "Exchange Ratio."  If, between the date of
this Agreement and the Effective Time, the outstanding shares of Company Common
Stock or Parent Common Stock are changed into a different number or class of
shares by reason of any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction, then the
Exchange Ratio shall be appropriately adjusted.

          (c) No fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and no certificates or scrip for any such fractional
shares shall be issued.  Any holder of Company Common Stock who would otherwise
be entitled to receive a fraction of a share of Parent Common Stock (after
aggregating all fractional shares of Parent Common Stock issuable to such
holder) shall, in lieu of such fraction of a share and, upon surrender of such
holder's Company Stock Certificate(s) (as defined in Section 1.6), be paid in
cash the dollar amount (rounded to the nearest whole cent), without interest,
determined by multiplying such

                                       3
<PAGE>
 
fraction by the closing price of a share of Parent Common Stock on the New York
Stock Exchange ("NYSE") on the date the Merger becomes effective.

     1.6  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective Time: (a)
all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist as provided in Section 1.5(a), and all holders of certificates
representing shares of Company Common Stock that were outstanding immediately
prior to the Effective Time shall cease to have any rights as stockholders of
the Company; and (b) the stock transfer books of the Company shall be closed
with respect to all shares of Company Common Stock outstanding immediately prior
to the Effective Time.  No further transfer of any such shares of Company Common
Stock shall be made on such stock transfer books after the Effective Time.  If,
after the Effective Time, a valid certificate previously representing any of
such shares of Company Common Stock (a "Company Stock Certificate") is presented
to the Exchange Agent (as defined in Section 1.7) or to the Surviving
Corporation or Parent, such Company Stock Certificate shall be canceled and
shall be exchanged as provided in Section 1.7.

     1.7  EXCHANGE OF CERTIFICATES.

          (a) On or prior to the Closing Date, Parent shall select a reputable
bank or trust company to act as exchange agent in the Merger (the "Exchange
Agent").  Promptly after the Effective Time, Parent shall deposit with the
Exchange Agent (i) certificates representing the shares of Parent Common Stock
issuable pursuant to this Section 1, and (ii) cash sufficient to make payments
in lieu of fractional shares in accordance with Section 1.5(c).  The shares of
Parent Common Stock and cash amounts so deposited with the Exchange Agent,
together with any dividends or distributions received by the Exchange Agent with
respect to such shares, are referred to collectively as the "Exchange Fund."

          (b) As soon as reasonably practicable after the Effective Time, the
Exchange Agent will mail to the record holders of Company Stock Certificates (i)
a letter of transmittal in customary form and containing such provisions as
Parent may reasonably specify (including a provision confirming that delivery of
Company Stock Certificates shall be effected, and risk of loss and title to
Company Stock Certificates shall pass, only upon delivery of such Company Stock
Certificates to the Exchange Agent), and (ii) instructions for use in effecting
the surrender of Company Stock Certificates in exchange for certificates
representing Parent Common Stock.  Upon surrender of a Company Stock Certificate
to the Exchange Agent for exchange, together with a duly executed letter of
transmittal and such other documents as may be reasonably required by the
Exchange Agent or Parent, (1) the holder of such Company Stock Certificate shall
be entitled to receive in exchange therefor a certificate representing the
number of whole shares of Parent Common Stock that such holder has the right to
receive pursuant to the provisions of Section 1.5 (and cash in lieu of any
fractional share of Parent Common Stock), and (2) the Company Stock Certificate
so surrendered shall be canceled.  Until surrendered as contemplated by this
Section 1.7(b), each Company Stock Certificate shall be deemed, from and after
the Effective Time, to represent only the right to receive shares of Parent
Common Stock (and cash in lieu of any fractional share of Parent Common Stock)
as contemplated by Section 1.  If any Company Stock Certificate shall have been
lost, stolen or destroyed, Parent may, in

                                       4
<PAGE>
 
its discretion and as a condition precedent to the issuance of any certificate
representing Parent Common Stock, require the owner of such lost, stolen or
destroyed Company Stock Certificate to provide an appropriate affidavit and to
deliver a bond (in such sum as Parent may reasonably direct) as indemnity
against any claim that may be made against the Exchange Agent, Parent or the
Surviving Corporation with respect to such Company Stock Certificate.

          (c) No dividends or other distributions declared or made with respect
to Parent Common Stock with a record date after the Effective Time shall be paid
to the holder of any unsurrendered Company Stock Certificate with respect to the
shares of Parent Common Stock which such holder has the right to receive upon
surrender thereof until such holder surrenders such Company Stock Certificate in
accordance with this Section 1.7 (at which time such holder shall be entitled,
subject to the effect of applicable escheat or similar laws, to receive all such
dividends and distributions, without interest).

          (d) Any portion of the Exchange Fund that remains undistributed to
holders of Company Stock Certificates as of the date 180 days after the date on
which the Merger becomes effective shall be delivered to Parent upon demand, and
any holders of Company Stock Certificates who have not theretofore surrendered
their Company Stock Certificates in accordance with this Section 1.7 shall
thereafter look only to Parent for satisfaction of their claims for Parent
Common Stock, cash in lieu of fractional shares of Parent Common Stock and any
dividends or distributions with respect to Parent Common Stock.

          (e) Each of the Exchange Agent, Parent and the Surviving Corporation
shall be entitled to deduct and withhold from any consideration payable or
otherwise deliverable pursuant to this Agreement to any holder or former holder
of Company Common Stock such amounts as may be required to be deducted or
withheld therefrom under the Code or any provision of state, local or foreign
tax law or under any other applicable Legal Requirement.  To the extent such
amounts are so deducted or withheld, such amounts shall be treated for all
purposes under this Agreement as having been paid to the Person to whom such
amounts would otherwise have been paid.

          (f) Neither Parent nor the Surviving Corporation shall be liable to
any holder or former holder of Company Common Stock or to any other Person with
respect to any shares of Parent Common Stock (or dividends or distributions with
respect thereto), or for any cash amounts, delivered to any public official
pursuant to any applicable abandoned property law, escheat law or similar Legal
Requirement.

     1.8  TAX CONSEQUENCES.  For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code.  The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

     1.9  ACCOUNTING CONSEQUENCES.  For financial reporting purposes, the Merger
is intended to be accounted for as a "pooling of interests."

                                       5

      1.10 FURTHER ACTION. If, at any time after the Effective Time, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full right,
title and possession of and to all rights and property of Merger Sub and the
Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

     2.8  PROPRIETARY ASSETS.

          (a) The Acquired Corporations own, or are licensed or otherwise

service marks, copyrights, and any applications therefor, maskworks, net lists,
schematics, technology, know-how, trade secrets, inventory, ideas, algorithms,

object code form), and tangible or intangible proprietary information or
material ("Intellectual Property") that are used or proposed to be used in the
business of the Acquired Corporations as currently conducted or as proposed to
be conducted by the Acquired Corporations, except to the extent that the failure
to have such rights has not had and would not reasonably be expected to have a
Material Adverse Effect on the Acquired Corporations.

patents and patent applications and all registered and unregistered trademarks,
trade names and service marks, registered and unregistered copyrights, and

Acquired Corporations.

          (e) All patents, registered trademarks, service marks and copyrights
held by the Acquired Corporations are valid and subsisting. Except for actions

licensing or sale of the Company's products does not infringe any patent,
trademark, service mark, copyright, trade secret or other proprietary right of
any third party, except where such infringement would not have a Material
Adverse Effect on the Acquired Corporations.

Corporations have taken all reasonable and appropriate steps to protect and
preserve the confidentiality of all Intellectual Property not otherwise

<PAGE>
 
Agreement; and the execution, delivery and performance by Parent and Merger Sub
of this Agreement have been duly authorized by all necessary action on the part
of Parent and Merger Sub and their respective boards of directors. This
Agreement constitutes the legal, valid and binding obligation of Parent and
Merger Sub, enforceable against them in accordance with its terms, subject to

injunctive relief and other equitable remedies.

     3.7  NO VOTE REQUIRED.  No vote of the holders of Parent Common Stock is
required to authorize the Merger.

provision of the certificate of incorporation or bylaws of Parent or the
certificate of incorporation or bylaws of Merger Sub, (b) result in a default by
Parent or Merger Sub under any Contract to which Parent or Merger Sub is a
party, except for any default which has not had and will not have a Material
Adverse Effect on Parent, or (c) result in a violation by Parent or Merger Sub

validly issued, fully paid and nonassessable.

     3.10 ACCOUNTING MATTERS.  To the knowledge of Parent, neither Parent nor
any of its affiliates has taken or agreed to, or plans to, take any action that
could prevent Parent from accounting for the Merger as a "pooling of interests."
Parent has received a letter dated the date of this Agreement, from Coopers &
Lybrand llp, a copy of which has been delivered to the Company, regarding
Coopers & Lybrand's belief (subject to the qualifications contained in such
letter) that the Merger should be treated as a "pooling of interests" in

Accounting Principles Board Opinion No. 16 and the applicable rules and
regulations of the SEC.

false or misleading with respect to any material fact, or (ii) omit to state any
material fact necessary in order to make the representations and warranties
contained in Section 3 and to be contained in such certificate (in 

                                      24

light of the circumstances under which such representations and warranties are

connection with or in response to an Acquisition Proposal, (iii) engage in
discussions or negotiations with any Person with respect to any Acquisition

Exchange Act; and (B) prior to the adoption and approval of this Agreement by
the Required Company Stockholder Vote, the Company shall not be prohibited by
this Section 4.3(a) from (x) furnishing nonpublic information regarding the
Acquired Corporations to any Person in response to an Acquisition Proposal that
is submitted by such Person (and not withdrawn), or (y) entering into
discussions with any Person in response to a Superior Offer that is submitted by
such Person (and not withdrawn) if, in either such case: (1) neither the Company
nor any Representative of any of the Acquired Corporations shall have violated
any of the restrictions set forth in this Section 4.3, (2) the Board of
Directors of the Company believes in good faith, based upon the advice of its
outside legal counsel, that such action is required in order for the board of
directors of the Company to comply with its fiduciary obligations to the
Company's stockholders under applicable law, (3) prior to furnishing any such
nonpublic information to, or entering into discussions with, such Person, the
Company gives Parent written notice of the identity of such Person and of the
Company's intention to furnish nonpublic information to, or enter into
discussions with, such Person, and the Company receives from such Person an
executed confidentiality agreement containing limitations no less restrictive
than the limitations imposed on Parent pursuant to the Confidentiality Agreement

restrictions set forth in the preceding sentence by any Representative of any of
the Acquired Corporations, whether or not such Representative is purporting to
act on behalf of any of the Acquired Corporations, shall be deemed to constitute
a breach of this Section 4.3 by the Company; provided, however, that this
sentence shall not limit the rights of any Representative who is a stockholder
of the Company to freely vote his stock and to exercise all of his rights as a
stockholder of the Company, subject to any contractual restrictions that may
apply.

          (b) The Company shall promptly advise Parent orally and in writing of
any Acquisition Proposal (including the identity of the Person making or
submitting such Acquisition Proposal and the terms thereof) that is made or
submitted by any Person during the Pre-Closing Period.  The Company shall keep

Proposal and any modification or proposed modification thereto.

          (c) The Company shall immediately cease and cause to be terminated any

          (a) As promptly as practicable after the date of this Agreement,
Parent and the Company shall prepare and cause to be filed with the SEC the
Prospectus/Proxy Statement and Parent shall prepare and cause to be filed with
the SEC the Form S-4 Registration Statement (in which the Prospectus/Proxy
Statement will be included as a prospectus); provided, however, that
notwithstanding anything to the contrary contained in this Section 5.1(a), if
(and to the extent) Parent so elects: (i) the Prospectus/Proxy Statement shall
initially be filed with the SEC on a confidential basis as a proxy statement of
the Company under Section 14 of the Exchange Act (and not as a registration
statement of Parent); (ii) until it is reasonably likely that the SEC will
declare the Form S-4 Registration Statement (in which the Prospectus/Proxy
Statement will be included as a prospectus) effective under the Securities Act,
all amendments to the Prospectus/Proxy Statement shall be filed with the SEC on
a confidential basis as amendments to the proxy statement of the Company under
Section 14 of the Exchange Act; and (iii) Parent shall not be obligated to file
the Form S-4 Registration Statement (in which the Prospectus/Proxy Statement
will be included as a prospectus) with the SEC until it is reasonably likely
that the SEC will promptly declare the Form S-4 Registration Statement effective
under the Securities Act.  Each of Parent and the Company shall use all
reasonable efforts to cause the Form S-4 Registration Statement and the
Prospectus/Proxy Statement to comply with the rules and regulations promulgated
by the SEC, to respond promptly to any comments of the SEC or its staff and to
have the Form S-4 Registration Statement declared effective under the Securities
Act as promptly as practicable after it is filed with the SEC.  The Company will
use all reasonable efforts to cause the Prospectus/Proxy Statement to be mailed
to the Company's stockholders as promptly as practicable after the Form S-4
Registration Statement is declared effective under the Securities Act.  The
Company shall promptly furnish to Parent all information concerning the Acquired
Corporations and the Company's stockholders that may be required or reasonably
requested in connection with any action contemplated by this Section 5.1.  If
any event relating to any of the Acquired Corporations occurs, or if the Company
becomes aware of any information, that should be disclosed in an amendment or
supplement to the Form S-4 Registration Statement or the Prospectus/Proxy
Statement, then the Company shall promptly inform Parent thereof and shall
cooperate with Parent in filing such amendment or supplement with the SEC and,
if appropriate, in mailing such amendment or supplement to the stockholders of
the Company.

          (b) Prior to the Effective Time, Parent shall use reasonable efforts
to obtain all regulatory approvals needed to ensure that the Parent Common Stock
to be issued in the Merger will be registered or qualified under the securities
law of every jurisdiction of the United States in which any registered holder of
Company Common Stock has an address of record on the record date for determining
the stockholders entitled to notice of and to vote at the Company Stockholders'
Meeting; provided, however, that Parent shall not be required (i) to qualify to
do business as a foreign corporation in any jurisdiction in which it is not now
qualified or (ii) to file a general consent to service of process in any
jurisdiction.

Legal Requirements to call, give notice of, convene and hold a meeting of the
holders of Company Common Stock to consider, act upon and vote upon the adoption
and approval of this Agreement and the approval of the Merger (the "Company
Stockholders' Meeting").  The Company Stockholders' Meeting will be held as
promptly as practicable and in any event within 45 days after the Form S-4
Registration Statement is declared effective under the Securities Act.  The
Company shall ensure that the Company Stockholders' Meeting is called, noticed,
convened, held and conducted, and that all proxies solicited in connection with
the Company Stockholders' Meeting are solicited, in compliance with all
applicable Legal Requirements.  The Company's obligation to call, give notice
of, convene and hold the Company Stockholders' Meeting in accordance with this
Section 5.2(a) shall not be limited or otherwise affected by the commencement,
disclosure, announcement or submission of any Superior Offer or other
Acquisition Proposal, or by any withdrawal, amendment or modification of the
recommendation of the board of directors of the Company with respect to the
Merger.

          (b) Subject to Section 5.2(c):  (i) the board of directors of the
Company shall unanimously recommend that the Company's stockholders vote in
favor of and adopt and approve this Agreement and approve the Merger at the
Company Stockholders' Meeting; (ii) the Prospectus/Proxy Statement shall include
a statement to the effect that the board of directors of the Company has
unanimously recommended that the Company's stockholders vote in favor of and
adopt and approve this Agreement and approve the Merger at the Company
Stockholders' Meeting; and (iii) neither the board of directors of the Company
nor any committee thereof shall withdraw, amend or modify, or propose or resolve
to withdraw, amend or modify, in a manner adverse to Parent, the unanimous
recommendation of the board of directors of the Company that the Company's
stockholders vote in favor of and adopt and approve this Agreement and approve
the Merger.  For purposes of this Agreement, said recommendation of the board of
directors of the Company shall be deemed to have been modified in a manner
adverse to Parent if said recommendation shall no longer be unanimous.

          (c) Nothing in Section 5.2(b) shall prevent the board of directors of
the Company from withdrawing, amending or modifying its unanimous recommendation
in favor of the Merger at any time prior to the adoption and approval of this
Agreement by the Required Company Stockholder Vote if (i) a Superior Offer is
made to the Company and is not withdrawn, (ii) neither the Company nor any of
its Representatives shall have violated any of the restrictions set forth in
Section 4.3, and (iii) the board of directors of the Company concludes in good
faith, based upon the advice of its outside counsel, that, in light of such
Superior Offer, the withdrawal, amendment or modification of such recommendation
is required in order for the board of directors of the Company to comply with
its fiduciary obligations to the Company's stockholders under applicable law.
Nothing contained in this Section 5.2 shall limit the Company's obligation to
call, give notice of, convene and hold the Company Stockholders' Meeting
(regardless of whether the unanimous recommendation of the board of directors of
the Company shall have been withdrawn, amended or modified).

another, in connection with any analysis, appearance, presentation, memorandum,
brief, argument, opinion or proposal made or submitted in connection with any
Legal Proceeding under or relating to the HSR Act or any other federal or state
antitrust or fair trade law.  In addition, except as may be prohibited by any

     5.4  STOCK OPTIONS AND COMPANY STOCK OPTION AND PURCHASE PLANS.

          (a) Subject to Section 5.4(b), at the Effective Time, all rights with
respect to Company Common Stock under each Company Option then outstanding shall
be converted into and become rights with respect to Parent Common Stock, and
Parent shall assume each such Company Option in accordance with the terms (as in
effect as of the date of this Agreement) of the Company Stock Option Plan under
which it was issued and the stock option agreement by which it is evidenced.
From and after the Effective Time, (i) each Company Option assumed by Parent may
be exercised solely for shares of Parent Common Stock, (ii) the number of shares
of Parent Common Stock subject to each such Company Option shall be equal to the
number of shares of Company Common Stock subject to such Company Option
immediately prior to the Effective Time multiplied by the Exchange Ratio,
rounding down to the nearest whole share (with cash, less the applicable
exercise price, being payable for any fraction of a share), (iii) the per share
exercise price under each such Company Option shall be adjusted by dividing the
per share exercise price under such Company Option by the Exchange Ratio and
rounding up to the nearest cent and (iv) any restriction on the exercise of any
such Company Option shall continue in full force and effect and the term,
exercisability, vesting schedule and other provisions of such 

                                      31
<PAGE>
 
Company Option shall otherwise remain unchanged; provided, however, that each
Company Option assumed by Parent in accordance with this Section 5.4(a) shall,
in accordance with its terms, be subject to further adjustment as appropriate to
reflect any stock split, stock dividend, reverse stock split, reclassification,
recapitalization or other similar transaction subsequent to the Effective Time.
Parent shall file with the SEC, no later than 30 days after the date on which
the Merger becomes effective, a registration statement on Form S-8 relating to
the shares of Parent Common Stock issuable with respect to the Company Options
assumed by Parent in accordance with this Section 5.4(a).

          (b) The Company shall take all action that may be necessary (under the
plans pursuant to which Company Options are outstanding and otherwise) to
effectuate the provisions of this Section 5.4 and to ensure that, from and after
the Effective Time, holders of Company Options have no rights with respect
thereto other than those specifically provided in this Section 5.4.

          (c) As of the Effective Time, the ESPP shall be terminated.  The

policies) exceeds $225,000, the Surviving Corporation shall be entitled to
reduce the amount of coverage of the Existing Policy (or any substitute
policies) to the amount of coverage that can be obtained for a premium equal to

Merger and Reorganization, dated as of the date hereof (the "Merger

share of common stock, par value $0.001 per share, of Infinity (the "Infinity

$0.01 per share, of SunGard (the "SunGard Common Stock"). The terms and
conditions of the Merger are more fully set forth in the Merger Agreement.
 
  You have asked for our opinion, as of the date hereof, as to whether the
Exchange Ratio pursuant to the Merger Agreement is fair from a financial point
of view to the holders of Infinity Common Stock.
 
  For purposes of the opinion set forth herein, we have:
 
  i.    analyzed certain publicly available financial statements and other
        information of SunGard and Infinity, respectively;
 
  ii.   analyzed certain internal financial statements and other financial and
        operating data concerning Infinity prepared by the management of
        Infinity;
 
  iii.  analyzed certain financial projections relating to Infinity prepared
        by the managements of Infinity and SunGard;
 
  iv.   discussed the past and current operations and financial condition and
        the prospects of Infinity with senior executives of Infinity;
 
  v.    analyzed certain internal financial statements and other financial and
        operating data concerning SunGard prepared by the management of SunGard;
 
  vii.  analyzed the pro forma impact of the Merger on the earnings per share
        and consolidated capitalization of SunGard;
 
  viii. reviewed the reported prices and trading activity for the Infinity
        Common Stock;
 
  ix.   compared the financial performance of Infinity and the prices and
        trading activity of the Infinity Common Stock with that of certain
        other comparable publicly traded companies and their securities;
 
  x.    reviewed the reported prices and trading activity for the SunGard Common
        Stock;
 
  xi.   compared the financial performance of SunGard and the prices and
        trading activity of the SunGard Common Stock with that of certain other
        comparable publicly traded companies and their securities;
 
  xii.  reviewed the financial terms, to the extent publicly available, of
        certain comparable merger and acquisition transactions;
 
  xiii. reviewed and discussed with the senior management of Infinity (i) the
        strategic rationale for the Merger and their assessment of the
        synergies and other benefits expected to be derived from the Merger
        and (ii) certain alternatives to the Merger;
 
  xiv.  participated in discussions and negotiations among representatives of
        Infinity and SunGard and their respective legal advisors;
 
                                      B-1
<PAGE>
 
  xv.  reviewed the Merger Agreement, and certain related agreements; and
 
  xvi. performed such other analyses and considered such other factors as we
       have deemed appropriate.
 
  We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us for the purposes
of this opinion. We have not been provided with, and therefore have not
reviewed, any internal financial projections or forecasts relating to future
operations or prospects of SunGard, and therefore, upon the advice of SunGard,
we have assumed that the publicly available estimates of research analysts are
a reasonable basis upon which to evaluate and analyze the future financial
performance of SunGard. With respect to the financial projections for
Infinity, we have assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the future
financial performance of Infinity. We have not made any independent valuation
or appraisal of the assets, liabilities or technology of SunGard or Infinity,
respectively, nor have we been furnished with any such appraisals. We have
assumed that the Merger will be accounted for as a "pooling-of-interests"
business combination in accordance with U.S. Generally Accepted Accounting
Principles and will be consummated in accordance with the terms set forth in
the Merger Agreement. Our opinion in necessarily based on economic, market and
other conditions as in effect on, and the information made available to us as
of, the date hereof.
 
  We have acted as financial advisor to the Board of Directors of Infinity in
connection with this transaction and will receive a fee for our services. In
the past, Deutsche Morgan Grenfell Inc. and its affiliates have provided
financing services for Infinity and have received fees for the rendering of
these services. In addition, in the ordinary course of our business, we may
actively trade the securities and loans of SunGard and Infinity for our own
account and for the accounts of our customers and, accordingly, may at any
time hold a long or short position in such securities and loans.
 
  It is understood that this letter is for the information of the Board of
Directors of Infinity only and may not be used for any other purpose without
our prior written consent, except that this opinion may be included in its
entirety in any filing made by Infinity with the Securities and Exchange
Commission with respect to the transactions contemplated by the Merger
Agreement. Our opinion does not address the underlying strategic decision by
Infinity to engage in the Merger and does not constitute a recommendation or
opinion as to how any holder of Infinity Common Stock should vote at the
shareholders' meeting held in connection with the Merger. In rendering this
opinion, we are not expressing any opinion as to the price at which the
SunGard Common Stock or Infinity Common Stock will actually trade at any time.
 
  Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a
financial point of view to holders of Infinity Common Stock.
 
                                          Very truly yours,

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Delaware General Corporation Law provides, in substance, that Delaware
corporations shall have the power, under specified circumstances, to indemnify
their directors, officers, employees and agents in connection with actions,
suits or proceedings brought against them by third parties and in connection
with actions or suits by or in the right of the corporation, by reason of the
fact that they were or are such directors, officers, employees and agents,
against expenses (including attorney's fees) and, in the case of actions,
suits or proceedings brought by third parties, against judgments, fines and
amounts paid in settlement actually and reasonably incurred in any action,
suit or proceeding.
 
  The Registrant's Bylaws provide for indemnifications to the fullest extent
permitted by the Delaware General Corporation Law. As permitted by the
Delaware General Corporation Law, the Registrant has adopted an amendment to
its Amended and Restated Certificate of Incorporation to eliminate the
personal liability of its directors to the Registrant and its stockholders, in
certain circumstances, for monetary damages arising from a breach of the
director's duty of care. Additionally, the Registrant has entered into
indemnification agreements (in the form approved by the Registrant's
stockholders at its 1987 Annual Meeting) with each of its directors and
officers. These agreements provide indemnification to the fullest extent
permitted by law and, in certain respects, provide greater protection than
that specifically provided by the Delaware General Corporation Law. The
agreements do not provide indemnification for, among other things, conduct
that is adjudged to be fraud, deliberate dishonesty or willful misconduct.
 
  The Registrant has obtained directors' and officers' liability insurance
that covers certain liabilities, including liabilities to the Registrant and
its stockholders, in the amount of $20 million.
 
  Pursuant to the Reorganization Agreement, all rights to indemnification
existing in favor of the persons serving as directors or officers of Infinity
as of the date of the Reorganization Agreement for acts and omissions
occurring prior to the Effective Time, as provided in Infinity's Bylaws (as in
effect as of the date of the Reorganization Agreement) and as provided in the
indemnification agreements between Infinity and said directors and officers
(as in effect as of the date of the Reorganization Agreement), shall survive
the Merger and the Registrant shall cause the Surviving Corporation to perform
all of its obligations arising thereunder for a period of not less than six
years from the Effective Time. The Reorganization Agreement also provides that
from the Effective Time until the third anniversary of the date on which the
Effective Time occurs, the Registrant will cause the Surviving Corporation to
maintain in effect, for the benefit of the persons serving as directors and
officers of Infinity as of the date of the Reorganization Agreement with
respect to acts or omissions occurring prior to the Effective Time, the
existing policy of directors' and officers' liability insurance maintained by
Infinity as of the date of the Reorganization Agreement (the "Existing
Policy"); provided, however, that (i) the Surviving Corporation may substitute
for the Existing Policy a policy or policies of comparable coverage, and (ii)
the Surviving Corporation shall not be required to pay an annual premium for
the Existing Policy (or for any substitute policies) in excess of $225,000.
The Reorganization Agreement further provides that in the event any future
annual premium for the Existing Policy (or any substitute policies) exceeds
$225,000, the Surviving Corporation shall be entitled to reduce the amount of
coverage of the Existing Policy (or any substitute policies) to the amount of
coverage that can be obtained for a premium equal to $225,000.

  The information required to be set forth herein with respect to Infinity is

  the fiscal year ended December 31, 1996. No financial data schedules are
  required for the Registrant.
 
  (c) Item 4(b) Reports
 
  See Appendix B to the Proxy Statement/Prospectus.
 
ITEM 22. UNDERTAKINGS.
 
  (1) The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the Proxy Statement/Prospectus pursuant
to Items 4, 10(b), 11 or 13 of Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through
the date of responding to the request.
 
  (2) The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.
 
  (3) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
                                     II-2

  (4) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act") may be permitted to directors, officers
and controlling persons of the Registrant pursuant to the Restated Certificate
of Incorporation (the "Certificate of Incorporation") and the Amended and
Restated Bylaws (the "Bylaws") of the Registrant and the Delaware General
Corporation Law, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer
or controlling person of the Registrant in a successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the question has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
  (5) (A) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of
a prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
  (B) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (A) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.

Gentlemen:

I am Vice President and General Counsel of SunGard Data Systems Inc.
("Company"). This opinion is being furnished in connection with a Registration
Statement on Form S-4 ("Registration Statement") to be filed by the Company
with the Securities Exchange Commission covering the offer and sale of
13,575,236 shares of the Company's common stock, par value $.01 per share
("Common Stock") to be issued in connection with the merger of Information
Data Inc., a Delaware corporation and a wholly owned subsidiary of the
Company, with and into Infinity Financial Technology, Inc., a Delaware
corporation. This opinion is furnished pursuant to the requirement of item
601(b)(5) of Regulation S-K. Defined terms as used herein shall have the
meanings attributed to such terms in the Registration Statement unless
otherwise stated herein.

In rendering this opinion, we have examined the following documents: (i) the
Company's Certificate of Incorporation and By-laws, as amended and restated
since the inception of the Company, (ii) resolutions adopted by the Board of
Directors on October 14, 1997 and the minutes of the Board of Directors'
meeting on October 16, 1997, (iii) the Registration Statement and (iv) such
other documents, legal opinions and precedents, corporate and other records of
the Company, and certificates of public officials and officers of the Company
that we have deemed necessary or appropriate to provide a basis for the below
opinion. We have assumed and relied, as to questions of fact and mixed
questions of law and fact, on the truth, completeness, authenticity and due
authorization of all documents and records examined and the genuineness of all
signatures. This opinion is limited to Delaware General Corporation Law.

Based upon and subject to the foregoing, in our opinion, the shares of Common 
Stock of the Company which are being offered and sold by the Company pursuant to
the Registration Statement, when sold in the manner and for the consideration 
contemplated by the Registration Statement, will be legally issued, fully paid 
and non-assessable. 

We consent to the filing of this opinion as an Exhibit to the Registration 
Statement.

Sincerely,

/s/ Lawrence A. Gross

Ladies and Gentlemen:

This opinion is being delivered to you in connection with the Form S-4

(the "Reorganization Agreement") by and among SunGard Data Systems Inc., a

references, unless otherwise indicated, are to the Internal Revenue Code of 
1986, as amended (the "Code"). 

We have acted as special counsel to Parent and Merger Sub in connection with the
Merger. As such, and for the purpose of rendering this opinion, we have 
examined, and are relying upon (without any independent investigation or review 
thereof) the truth and accuracy, at all relevant times, of the statements, 
covenants, representations and warranties contained in, the following documents 
(including all exhibits and schedules attached thereto):

        (a)     the Reorganization Agreement;

        (b)     those certain tax representation letters dated November 12, 1997
delivered to us by Parent, Merger Sub and the Company containing certain 
representations of Parent, Merger Sub and the Company (the "Tax Representation 
Letters");

        (c)     Continuity of Interest Certificates dated October 17, 1997 by 
certain shareholders of the Company in favor of Parent, Merger Sub and the 
Company (the "Continuity of Interest Certificates"); and

        (d) such other instruments and documents related to the formation, 
organization and operation of Parent, Merger Sub and the Company and related to 
the consummation of the Merger and the other transactions contemplated by the 
Reorganization Agreement as we have deemed necessary or appropriate.

In connection with rendering this opinion, we have assumed (without any 
independent investigation or review thereof) that: 

        1. Original documents submitted to us (including signatures thereto) are
authentic, documents submitted to us as copies conform to the original 
documents, and that all such documents have been (or will be by the Effective 
Time) duly and validly executed and delivered where due execution and delivery 
are a prerequisite to the effectiveness thereof;

        2. All representations, warranties and statements made or agreed to by 
Parent, Merger Sub and the Company, their managements, employees, officers, 
directors and shareholders in connection with the Merger, including, but not 
limited to, those set forth in the Reorganization Agreement (including the 
exhibits thereto), the Tax Representation Letters and the Continuity of Interest
Certificates are true and accurate at all relevant times;

        3. All covenants contained in the Reorganization Agreement (including 
exhibits thereto), the Tax Representation Letters and the Continuity of Interest
Certificates are performed without waiver or breach of any material provision 
thereof;

        4. There is no plan or intention on the part of the shareholders of the 
Company to engage in a sale, exchange, transfer, distribution, pledge, or other 
disposition or any transaction which results in a reduction of risk of 
ownership, or a direct or indirect disposition of shares of Parent Common Stock 
to be received in the Merger that would reduce the Company's shareholders' 
ownership of Parent Common Stock to a number of shares having an aggregate fair 
market value, as of the Effective Time, of less than fifty percent (50%) of the 
aggregate fair market value of all of the Company Common Stock outstanding 
immediately prior to the Effective Time. (For purposes of the preceding 
sentence, shares of Company Common Stock pursuant to which shareholders of the 
Company exercise dissenters' rights in the Merger, which are exchanged for 
consideration in the Merger other than shares of Parent Common Stock, including 
being exchanged for cash in lieu of fractional shares of Parent Common Stock or 
are sold, redeemed or disposed of in a transaction that is in contemplation of 
or related to the Merger, shall be considered shares of Company Common Stock 
held by shareholders of the

Company immediately prior to the Merger which are exchanged for shares of Parent
Common Stock in the Merger and then disposed of pursuant to a plan); and 

        5. Any representation or statement made "to the best of knowledge" or 
similarly qualified is correct without such qualification.

Based on our examination of the foregoing items and subject to the limitations, 
qualifications, assumptions and caveats set forth herein, we are of the opinion 
that, for federal income tax purposes, the Merger will be a reorganization 
within the meaning of Section 368(a)(1) of the Code.

In addition to your request for our opinion on this specific matter of federal 
income tax law, you have asked us to review the discussion of federal income tax
issues contained in the Registration Statement. We have reviewed the discussion 
entitled "Certain Federal Income Tax Considerations" contained in the 
Registration Statement and believe that such information fairly presents the 
current federal income tax law applicable to the Merger and the material federal
tax consequences to Parent, Merger Sub, the Company and the Company's 
shareholders as a results of the Merger.

We consent to the reference to our firm under the caption "Certain Federal 
Income Tax Considerations" in the Proxy Statement included in the Registration 
Statement and to the filing of this opinion as an exhibit to the Proxy Statement
and to the Registration Statement.

This opinion does not address the various state, local or foreign tax 
consequences that may result from the Merger or the other transactions 
contemplated by the Reorganization Agreement except as specifically set forth 
herein, and this opinion may not be relied upon except with respect to the 
consequences specifically discussed herein.

No opinion is expressed as to any transaction other than the Merger as 
described in the Reorganization Agreement, or as to any other transaction 
whatsoever, including the Merger, if all of the transactions described in the 
Reorganization Agreement are not consummated in accordance with the terms of the
Reorganization Agreement and without waiver of any material provision thereof. 
To the extent that any of the representations, warranties, statements and 
assumptions material to our opinion and upon which we have relied are not 
accurate and
<PAGE>
 
SunGard Data Systems Inc. and
Information Data Inc.

Page 4

complete in all material respects at all relevant times, our opinion would be 
adversely affected and should not be relied upon.

This opinion only represents our best judgment as to the federal income tax 
consequences of the Merger and is not binding on the Internal Revenue Service or
any court of law, tribunal, administrative agency or other governmental body. 
The conclusions are based on the Code, existing judicial decisions, 
administration regulations and published rulings. No assurance can be given that
future legislative, judicial or administrative changes or interpretations would 
not adversely affect the accuracy of the conclusions stated herein. 
Nevertheless, by rendering this opinion, we undertake no responsibility to 
advise you of any new developments in the application or interpretation of the 
federal income tax laws.

This opinion is being delivered in connection with the filing of the
Registration Statement. It is intended solely for the benefit of Parent and
Merger Sub and may not be relied upon or utilized for any other purpose or by
any other person and may not be made available to any other person without our
prior written consent.


Sincerely,


COOLEY GODWARD LLP

Re:  MERGER AMONG SUNGARD DATA SYSTEMS, INC., INFORMATION DATA INC. AND INFINITY
     FINANCIAL TECHNOLOGY, INC.

Ladies and Gentlemen:

     We have acted as special counsel to Infinity Financial Technology, Inc., a
Delaware corporation (the "Company") in connection with its acquisition by
SunGard Data Systems Inc., a Delaware corporation ("SunGard"), pursuant to that
certain Agreement and Plan of Merger and Reorganization, dated as of October 17,
1997 (the "Agreement"), by and among SunGard, Information Data Inc., a Delaware
corporation and wholly-owned subsidiary of SunGard ("Merger Sub"), and the
Company.  Pursuant to the Agreement, Merger Sub will merge into and with the
Company, with the Company surviving (the "Merger").  Capitalized terms not
defined herein shall have the meanings ascribed to them in the Agreement or in
the certificates relevant to this opinion delivered to Morrison & Foerster LLP
and Cooley Godward LLP by (i) the respective managements of SunGard and the
Company and (ii) certain holders of Company Common Stock  (collectively, the
"Certificates of Representations").

     You have requested our opinion as to certain federal income tax matters
regarding the Merger.  This opinion is solely for the benefit of the Company and
the holders of Company Common Stock ("Company Stockholders") and may not be
relied upon or provided to any other party, including, but not limited to,
SunGard, its stockholders, and/or holders of options for shares of Company
Common Stock, without our express written consent.

     In our capacity as special counsel to the Company with respect to the
Merger and for purposes of rendering this opinion, we have examined and relied
upon the following, with your consent: (i) the Agreement; (ii) the Certificates
of Representations; (iii) the Registration Statement on Form S-4 (the
"Registration Statement"), which was filed with the Securities and Exchange
Commission on November 12, 1997, and which includes the Prospectus of SunGard
and Proxy Statement of the Company relating to the Agreement; (iv) an opinion of
special counsel received by SunGard and Merger Sub from Cooley Godward LLP; and
(v) such other documents that we considered relevant to 
<PAGE>
 
Infinity Financial Technology, Inc.
November 12, 1997
Page Two


our analysis. We have assumed that all parties to the Agreement and to any other
documents examined by us have acted, and will act, in accordance with the terms
of such documents (including the assumption that the Merger will be consummated
at the Effective Time pursuant to the terms and conditions set forth in the
Agreement and in accordance with laws of Delaware). In our examination of such
documents, we have assumed the authenticity of original documents, the accuracy
of copies, the genuineness of signatures, and the legal capacity of signatories.

     Furthermore, our opinion is based on our understanding of the facts as
represented to us in the Certificates of Representations.  We have also assumed
that all representations contained in the Agreement, as well as those
representations contained in the Certificates of Representations are, and at the
Effective Time will be, true and complete in all material respects.  We have not
undertaken any independent inquiry into or verification of these facts either in
the course of our representation of the Company or for the purposes of rendering
this opinion.  While we have reviewed such representations to ensure that they
appear reasonable, we have no assurance that these expectations will ultimately
prove to be accurate.  To the extent the facts differ from those relied on and
assumed herein, our opinion should not be relied upon.

     The conclusions expressed herein represent our judgment of the proper
treatment of certain aspects of the Merger under the income tax laws of the
United States based upon the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury Regulations, rulings and other pronouncements of the
Internal Revenue Service (the "IRS") currently in effect, and judicial
decisions, all of which are subject to change, prospectively or retroactively.
No assurance can be given that such changes will not take place, or that such
changes would not affect the conclusions expressed herein.  Furthermore, our
opinion represents only our best judgment of how a court would conclude if
presented with the issues addressed herein and is not binding upon either the
IRS or any court.  Thus, no assurance can be given that a position taken in
reliance on our opinion will not be challenged by the IRS or rejected by a
court.

     Our opinion relates solely to the tax consequences of the Merger under the
federal income tax laws of the United States, and we express no opinion (and no
opinion should be inferred) regarding the tax consequences of the Merger under
the laws of any other jurisdiction.  This opinion addresses only the specific
issues set forth below, and does not address any other tax consequences that may
result from the Merger or any other transaction (including any transaction
undertaken in connection with the Merger).

     No opinion is expressed as to any transaction other than the Merger as
described in the Registration Statement or as to any transaction whatsoever,
including the Merger, 
<PAGE>
 
Infinity Financial Technology, Inc.

if all the transactions described in the Registration Statement are not
consummated in accordance with such description or the terms of the Agreement
without waiver or breach of any material provision thereof, or if all of the
representations, warranties, statements and assumptions upon which we relied are
not true, correct and complete at all relevant times. In the event any one of
the statements, representations, warranties or assumptions upon which we have
relied to issue this opinion is incorrect, our opinion might be adversely
affected and may not be relied upon.

     On the basis of, and subject to the foregoing, we are of the opinion that:

     (1) The Merger will be a reorganization within the meaning of Section
368(a)(1) of the Code; and

     (2) The discussion under the caption "Certain Federal Income Tax
Considerations" in the Registration Statement provides the material United
States federal income tax consequences to SunGard, the Company and Company
Stockholders if the Merger is effected according to the terms of the Agreement.

     We hereby consent to the use of this opinion in the Registration Statement
and the reference to us therein under the caption "Certain Federal Income Tax
Considerations" and "Legal Matters."  In giving this consent, we do not thereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Securities Act of 1933.


                              Very truly yours,

                               IRREVOCABLE PROXY


     The undersigned stockholder of Infinity Financial Technology, Inc., a

permitted by law) appoints and constitutes Lawrence A. Gross, Richard C. Tarbox

     This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between

consideration of Parent entering into the Agreement and Plan of Merger and
Reorganization, dated as of the date hereof, among Parent, Information Data

actions contemplated by the Reorganization Agreement and any action required in
furtherance hereof and thereof.

     The undersigned stockholder may vote the Shares on all other matters.

     This proxy shall be binding upon the heirs, successors and assigns of the

enforceability of any of the terms or provisions of this proxy in any other
jurisdiction.  If any provision of this proxy is so broad as to be

enforceable.

     This proxy shall terminate upon the Expiration Date.

                              AFFILIATE AGREEMENT

     THIS AFFILIATE AGREEMENT is being executed and delivered as of October 17,
1997 by ________________________ ("Stockholder") in favor of and for the benefit
of SUNGARD DATA SYSTEMS INC., a Delaware corporation ("Parent").

                                   RECITALS

     A.  Stockholder is a stockholder of, and is an officer and/or director of,
INFINITY FINANCIAL TECHNOLOGY, INC., a Delaware corporation (the "Company").

     B.  Parent, the Company and Information Data Inc., a Delaware corporation
and a wholly owned subsidiary of Parent ("Merger Sub"), have entered into an
Agreement and Plan of Merger and Reorganization dated as of October 17, 1997
(the "Reorganization Agreement"), providing for the merger of Merger Sub into
the Company (the "Merger"). The Reorganization Agreement contemplates that, upon
consummation of the Merger, (i) holders of shares of the common stock of the 
Company will receive shares of common stock of Parent ("Parent Common Stock") in
exchange for their shares of common stock of the Company and (ii) the Company 
will become a wholly owned subsidiary of Parent. It is accordingly contemplated 
that Stockholder will receive shares of Parent Common Stock in the Merger.

     C.  Stockholder understands that the Parent Common Stock being issued in 
the Merger will be issued pursuant to a registration statement on Form S-4, and 
that Stockholder may be deemed an "affiliate" of Parent: (i) as such term is 
defined for purposes of paragraphs (c) and (d) of Rule 145 under the Securities 
Act of 1933, as amended (the "Act"); and (ii) for purposes of determining 
Parent's eligibility to account for the Merger as a "pooling of interests" under
Accounting Series Releases 130 and 135, as amended, of the Securities and 
Exchange Commission (the "SEC"), and under other applicable "pooling of 
interests" accounting requirements.

                                   AGREEMENT

     1.   REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER. Stockholder represents 
and warrants to Parent as follows:

          (a) Stockholder is the holder and "beneficial owner" (as defined in 
Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of the number 
of shares of common stock of the Company set forth beneath Stockholder's 
signature on the signature page hereof (the "Company Shares"), and Stockholder 
has good and valid title to the Company Shares, free and clear of any liens, 
pledges, security interests, adverse claims, equities, options, proxies, 
charges, encumbrances or restrictions of any nature.

<PAGE>
 
           (b) Stockholder has carefully read this Affiliate Agreement and, to 
the extent Stockholder felt necessary, has discussed with counsel the 
limitations imposed on Stockholder's ability to sell, transfer or otherwise 
dispose of the Company Shares and the shares of Parent Common Stock that 
Stockholder is to receive in the Merger (the "Parent Shares"). Stockholder fully
understands the limitations this Affiliate Agreement places upon Stockholder's 
ability to sell, transfer, or otherwise dispose of the Company Shares and the 
Parent Shares.

           (c) Stockholder understands that the representations, warranties and 
covenants set forth in this Affiliate Agreement will be relied upon by Parent 
and its counsel and accountants for purposes of determining Parent's eligibility
to account for the Merger as a "pooling of interests" and for purposes of 
determining whether Parent should proceed with the Merger.

      2.   REPRESENTATION AND WARRANTY OF PARENT. Parent represents and warrants
to Stockholder that it shall make available adequate current public information 
as required by Rule 144(c) promulgated by the SEC under the Act.

      3.   PROHIBITIONS AGAINST TRANSFER.

           (a) Stockholder agrees that, during the period from the date 30 days 
prior to the date of consummation of the Merger through the date on which 
financial results covering at least 30 days of post-Merger combined operations
of Parent and the Company have been published by Parent (within the meaning of
the applicable "pooling of interests" accounting requirements):

               (i)  Stockholder shall not sell, transfer or otherwise dispose 
            of, or reduce Stockholder's interest in or risk relating to, (A) any
            capital stock of the Company (including, without limitation, the
            Company Shares and any additional shares of capital stock of the
            Company acquired by Stockholder, whether upon exercise of a stock
            option or otherwise), except pursuant to and upon consummation of
            the Merger, or (B) any option or other right to purchase any shares
            of capital stock of the Company, except pursuant to and upon
            consummation of the Merger; and


               (ii) Stockholder shall not sell, transfer or otherwise dispose of
             or, or reduce Stockholder's interest in or risk relating to, (A)
             any shares of capital stock of the Parent (including without
             limitation the Parent Shares and any additional shares of capital
             stock of Parent acquired by Stockholder, whether upon exercise of
             a stock option or otherwise), or (B) any option or other right to
             purchase any shares of capital stock of Parent.

           (b) Stockholder agrees that Stockholder shall not effect any sale, 
transfer or other disposition of any Parent Shares unless:

               (i)  such sale, transfer or other disposition is effected 
             pursuant to an effective registration statement under the Act;

                                      2.
<PAGE>
 
             (ii)  such sale, transfer or other disposition is made in
          conformity with the requirements of Rule 145 under the Act, as
          evidenced by a broker's letter and a representation letter executed by
          Stockholder (satisfactory in form and content to Parent) stating that
          such requirements have been met;

             (iii)  counsel reasonably satisfactory to Parent shall have advised
          Parent in a written opinion letter (satisfactory in form and content
          to Parent), upon which Parent may rely, that such sale, transfer or
          other disposition will be exempt from registration under the Act; or

             (iv)  an authorized representative of the SEC shall have rendered
          written advice to Stockholder to the effect that the SEC would take no
          action, or that the staff of the SEC would not recommend that the SEC
          take action, with respect to such sale, transfer or other
          disposition, and a copy of such written advice and all other related
          communications with the SEC shall have been delivered to Parent.


     4.   STOP TRANSFER INSTRUCTIONS; LEGEND.

          Stockholder acknowledges and agrees that (a) stop transfer 
instructions will be given to Parent's transfer agent with respect to the Parent
Shares, and (b) each certificate representing any of such shares shall bear a 
legend identical or similar in effect to the following legend (together with any
other legend or legends required by applicable state securities laws or 
otherwise):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
          TRANSACTION TO WHICH RULE 145(d) OF THE SECURITIES ACT OF 1933
          AND "POOLING OF INTERESTS" ACCOUNTING TREATMENT APPLY AND MAY
          NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED
          OR HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH
          RULE, IN ACCORDANCE WITH THE REQUIREMENTS FOR "POOLING OF
          INTERESTS" ACCOUNTING TREATMENT AND IN ACCORDANCE WITH THE TERMS
          OF AN AGREEMENT DATED AS OF OCTOBER 17, 1997, BETWEEN THE
          REGISTERED HOLDER HEREOF AND THE ISSUER, A COPY OF WHICH IS ON
          FILE AT THE PRINCIPAL OFFICES OF THE ISSUER."

          5.  INDEPENDENCE OF OBLIGATIONS. The covenants and obligations of 
Stockholder set forth in this Affiliate Agreement shall be construed as 
independent of any other agreement or arrangement between Stockholder, on the
one hand, and the Company or Parent, on the other. The existence of any claim or
cause of action by Stockholder against the Company or Parent shall not
constitute a defense to the enforcement of any of such covenants or obligations
against Stockholder.
