    Any stockholder desiring to tender all or any portion of such stockholder's
Shares, and the associated Rights, should either (a) complete and sign the
Letter of Transmittal (or a facsimile thereof) in accordance with the
instructions in the Letter of Transmittal and mail or deliver it together with
the certificate(s) representing tendered Shares and, if separate, the

whose Shares and, if applicable, associated Rights are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee must contact

desires to tender such Shares and, if applicable, the associated Rights. Unless
and until the Purchaser declares that the Rights Condition (as hereinafter
defined) is satisfied, stockholders will be required to tender one associated
Right for each Share tendered in order to effect a valid tender of such Share.
 
    A stockholder who desires to tender his Shares and associated Rights, and
whose certificates representing such Shares (and, if applicable, associated
Rights) are not immediately available or who cannot comply with the procedures
for book-entry transfer on a timely basis may tender such Shares (and, if
applicable, associated Rights) by following the procedures for guaranteed
delivery set forth in Section 3.
 
    ON FEBRUARY 2, 1998, THE COMPANY PUBLICLY ANNOUNCED A TWO-FOR-ONE SPLIT OF
THE SHARES (THE "ANNOUNCED STOCK SPLIT") IN THE FORM OF A 100% STOCK DIVIDEND
THEREON (THE "STOCK SPLIT DIVIDEND"). THE COMPANY FURTHER ANNOUNCED THAT THE
STOCK SPLIT DIVIDEND WILL BE PAYABLE ON MARCH 23, 1998 TO HOLDERS OF SHARES OF
RECORD ON MARCH 2, 1998. UNLESS THE COMPANY RESCINDS THE ANNOUNCED STOCK SPLIT
AND THE STOCK SPLIT DIVIDEND PRIOR TO THE RECORD DATE THEREFOR AND THE PURCHASER
DETERMINES, IN ITS SOLE DISCRETION, THAT THE HOLDERS OF SHARES HAVE NO FURTHER
RIGHTS WITH RESPECT TO THE ANNOUNCED STOCK SPLIT AND THE STOCK SPLIT DIVIDEND,
THE PURCHASER, IN ITS SOLE DISCRETION, MAY MAKE SUCH ADJUSTMENTS AS IT DEEMS
APPROPRIATE IN THE PURCHASE PRICE AND OTHER TERMS OF THE OFFER, INCLUDING
(WITHOUT LIMITATION) IN THE NUMBER OF SECURITIES REQUIRED TO SATISFY THE MINIMUM
CONDITION (AS HEREINAFTER DEFINED) AND REQUIRING TENDERING STOCKHOLDERS
RECEIVING THE STOCK SPLIT DIVIDEND, IF ANY, TO RECEIVE AND HOLD SUCH DIVIDEND
FOR THE ACCOUNT OF THE PURCHASER AND PROMPTLY REMIT AND TRANSFER SUCH DIVIDEND
TO THE DEPOSITARY FOR THE ACCOUNT OF THE PURCHASER. IF THE EXPIRATION DATE (AS
HEREINAFTER DEFINED) OCCURS PRIOR TO MARCH 23, 1998, THE PURCHASER INTENDS TO
REQUIRE TENDERING STOCKHOLDERS RECEIVING THE STOCK SPLIT DIVIDEND, IF ANY, TO
RECEIVE AND HOLD SUCH DIVIDEND FOR THE ACCOUNT OF THE PURCHASER AND PROMPTLY
REMIT AND TRANSFER SUCH DIVIDEND TO THE DEPOSITARY FOR THE ACCOUNT OF THE
PURCHASER AS A CONDITION TO A TENDER BEING VALID AND SUCH STOCKHOLDER BEING
ENTITLED TO RECEIVE PAYMENT FOR SUCH TENDERED SHARES. IN THIS EVENT, THE
PURCHASE PRICE OF $108 PER SHARE WILL NOT BE ADJUSTED. IF, HOWEVER, THE
EXPIRATION DATE OCCURS ON OR AFTER MARCH 23, 1998, THE PURCHASER ANTICIPATES
THAT THE PURCHASE PRICE FOR THE SHARES PURSUANT TO THE OFFER WILL BE ADJUSTED
FOR THE EFFECT OF THE ANNOUNCED STOCK SPLIT TO AN AMOUNT EQUAL TO $54 PER SHARE
FOR EACH SPLIT-ADJUSTED SHARE AND THAT THE MINIMUM CONDITION WILL BE DETERMINED
BY REFERENCE TO SUCH INCREASED AMOUNT OF SHARES OUTSTANDING. SEE SECTION 13.

To the Holders of Shares of Common Stock
  (including the Associated Preferred Stock
  Purchase Rights) of Computer Sciences Corporation:
 
                                  INTRODUCTION
 
    CAI Computer Services Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of Computer Associates International, Inc., a Delaware
corporation ("Computer Associates"), hereby offers to purchase all outstanding
shares of Common Stock, par value $1.00 per share (the "Shares"), of Computer
Sciences Corporation, a Nevada corporation (the "Company"), together with
(unless and until the Purchaser declares that the Rights Condition (as defined
below) has been satisfied) the associated Series A Junior Participating
Preferred Stock Purchase Rights (the "Rights") issued pursuant to the Rights
Agreement, dated as of December 21, 1988, amended and restated as of August 1,
1996 (the "Rights Agreement"), between the Company and ChaseMellon Shareholder
Services, L.L.C., as Rights Agent (the "Rights Agent"), at a purchase price of
$108 per Share (and associated Right), net to the seller in cash, without
interest thereon, in each case upon the terms and subject to the conditions set
forth in this Offer to Purchase and in the related Letter of Transmittal (which,
together with any amendments or supplements hereto or thereto, collectively
constitute the "Offer"). Unless the context otherwise requires, (i) all
references to "Shares" shall include the associated Rights, (ii) all references
to the "Rights" shall include all benefits that may inure to holders of the
Rights pursuant to the Rights Agreement and (iii) all references to "Shares"
shall include any shares issued pursuant to the Stock Split Dividend (as defined
below). On February 2, 1998, the Company publicly announced a two-for-one split
of the Shares (the "Announced Stock Split") in the form of a 100% stock dividend
thereon (the "Stock Split Dividend"). The Company further announced that the
Stock Split Dividend will be payable on March 23, 1998 to holders of Shares of
record on March 2, 1998. The $108 per Share offered in the Offer has been
determined based on the Shares without giving effect to the Announced Stock
Split. Information with respect to the effect of the Announced Stock Split on
the terms of the Offer is set forth in Section 13.
 
    Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares or Rights by the
Purchaser pursuant to the Offer. However, any tendering stockholder or other
payee who fails to complete and sign the Substitute Form W-9 that is included in
the Letter of Transmittal may be subject to a required backup federal income tax
withholding of 31% of the gross proceeds payable to such stockholder or other
payee pursuant to the Offer. See Section 3. The Purchaser will pay all charges
and expenses of Bear, Stearns & Co. Inc., as Dealer Manager (the "Dealer
Manager"), First Chicago Trust Company of New York, as Depositary (the
"Depositary"), and MacKenzie Partners, Inc., as Information Agent (the
"Information Agent"), incurred in connection with the Offer. See Section 16.
 
    The purpose of the Offer is to enable Computer Associates to acquire control
of, and the entire equity interest in, the Company. The Offer, as the first step
in the acquisition of the Company, is intended to facilitate the acquisition of
all the Shares. Computer Associates currently intends, as soon as practicable
following consummation of the Offer, to propose and seek to have the Company
consummate a merger or similar business combination with the Purchaser or
another direct or indirect wholly owned subsidiary of Computer Associates (the
"Proposed Merger"). The purpose of the Proposed Merger is to acquire all Shares
not tendered and purchased pursuant to the Offer or otherwise. Pursuant to the
Proposed Merger, each then outstanding Share (other than Shares owned by the
Purchaser, Computer Associates or any of their subsidiaries, Shares held in the
treasury of the Company and Shares owned by stockholders who perfect any
available appraisal rights under Chapters 78 and 92A of the Nevada Revised
Statutes (the "Nevada Law")) would be converted into the right to receive an
amount in cash equal to the price per Share paid pursuant to the Offer.
 
    Although the Purchaser will seek to have the Company consummate the Proposed
Merger as soon as practicable after consummation of the Offer, if the Board of
Directors of the Company opposes the Offer
 
                                       1
<PAGE>
and the Proposed Merger, certain terms of the Rights and certain provisions of
the Nevada Law may affect the ability of the Purchaser to consummate the Offer,
to obtain control of the Company and to effect the Proposed Merger. Accordingly,
the timing and details of the Proposed Merger will depend on a variety of
factors and legal requirements, the actions of the Board of Directors of the
Company, the number of Shares acquired by the Purchaser pursuant to the Offer
and whether the Minimum Condition, the Rights Condition, the Control Share
Condition and the Business Combination Condition (each as defined below) are
satisfied or waived.
 
    Computer Associates intends to solicit (the "Solicitation") holders of
Shares with respect to one or more of (i) written consents to act in lieu of a
meeting, (ii) proxies to act at any meeting of stockholders held pursuant to the
Control Share Acquisition Statute (as defined below) and (iii) agent
designations for the call of a special meeting of holders of Shares pursuant to
Article II, Section 2 of the Company's Amended and Restated Bylaws (the
"Bylaws"), each to adopt or facilitate the adoption of the Proposals (as defined
below). The Proposals are targeted principally at (1) replacing the existing
directors of the Company with directors who are committed, subject to their
fiduciary duties, to removing any impediments to the ability of holders of
Shares to choose freely whether to accept the Offer and approve the Proposed
Merger (the "Director Replacement Proposals") and (2) clarifying that the
Company's Board of Directors may not delay the Company's annual meeting of
stockholders (the "Annual Meeting") at which Computer Associates will seek to
replace the Company's existing directors if this action cannot be accomplished
by consent or at a special meeting, and limiting the Board's ability to take
certain defensive actions (the "Anti-Entrenchment Proposals" and, together with
the Director Replacement Proposals, the "Proposals"). The Solicitation will be
made only pursuant to separate solicitation materials, preliminary copies of
which were filed with the Securities and Exchange Commission (the "Commission")
on February 17, 1998, which comply with the requirements of Section 14(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations promulgated thereunder.
 
    On February 17, 1998, Computer Associates filed its Complaint (the
"Complaint") for Injunctive and Declaratory Relief in the United States District
Court for the District of Nevada (the "Court"). The Complaint requests that the
Company be enjoined from taking actions to impede the exercise of the
shareholder franchise, or the consummation of the Offer, and that the Company be
required to render inapplicable various anti-takeover devices including the
Rights Agreement, so that the Offer may be consummated.
 
    The Complaint also seeks various declarations pursuant to the Nevada Law and
the Bylaws regarding the Solicitation. Computer Associates has asked the Court
to declare that the holders of a majority of the Shares may act, by written
consent or vote, to amend the Bylaws. Computer Associates also has asked the
Court to declare that the holders of two-thirds of the Shares may act, by
written consent or vote, to remove a sufficient number of the existing directors
to be able to designate a majority of the members of the Company's Board of
Directors. Computer Associates has moved the Court for an expedited
determination of these issues. That motion is pending before the Court.
 
    Computer Associates intends to continue to seek to negotiate with the
Company with respect to the acquisition of the Company by Computer Associates.
The Purchaser reserves the right to amend the Offer upon entry into an
acquisition agreement or other agreement regarding a business combination with
the Company or otherwise or to negotiate an acquisition agreement or other
agreement regarding a business combination with the Company not involving a
tender offer. See Section 14.
 
    THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF A PROXY, CONSENT OR
AUTHORIZATION FOR OR WITH RESPECT TO THE ANNUAL MEETING OR ANY SPECIAL MEETING
OF THE COMPANY'S STOCKHOLDERS. ANY SUCH SOLICITATION WHICH COMPUTER ASSOCIATES
OR THE PURCHASER MAY MAKE WILL BE MADE ONLY PURSUANT
 
                                       2
<PAGE>
TO SEPARATE SOLICITATION MATERIALS COMPLYING WITH ALL APPLICABLE REQUIREMENTS OF
SECTION 14(a) OF THE EXCHANGE ACT AND THE RULES AND REGULATIONS PROMULGATED
THEREUNDER.
 
CERTAIN CONDITIONS TO THE OFFER
 
    The Offer is subject to the fulfillment of certain conditions, including the
following:
 
    MINIMUM CONDITION.  CONSUMMATION OF THE OFFER IS CONDITIONED (THE "MINIMUM
CONDITION") UPON THERE BEING VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE
EXPIRATION DATE (AS DEFINED IN SECTION 1) A NUMBER OF SHARES, WHICH WHEN ADDED
TO THE NUMBER OF SHARES OWNED BY THE PURCHASER AND ITS AFFILIATES, CONSTITUTES A
MAJORITY OF THE TOTAL NUMBER OF OUTSTANDING SHARES ON A FULLY DILUTED BASIS ON
THE DATE OF PURCHASE.
 
    According to the Company's Quarterly Report on Form 10-Q for the quarter
ended December 26, 1997 (the "December 1997 10-Q"), at December 26, 1997,
77,952,347 Shares were issued and outstanding. According to the Company's Annual
Report on Form 10-K for the fiscal year ended March 28, 1997 (the "1997 10-K"),
at March 28, 1997, options covering a total of 6,578,881 Shares were outstanding
under the Company's various stock option plans. Computer Associates currently
beneficially owns 170,000 Shares. Based on the foregoing and assuming that no
options were granted after March 28, 1997, and no options were exercised or
expired from March 29, 1997 through December 26, 1997, there would be 84,531,228
Shares outstanding on a fully diluted basis and the Minimum Condition would be
satisfied if 42,095,614 Shares are validly tendered pursuant to the Offer and
not properly withdrawn. However, the actual number of Shares that must be
validly tendered pursuant to the Offer and not properly withdrawn in order to
satisfy the Minimum Condition will depend on the facts as they exist on the date
of purchase.
 
    RIGHTS CONDITION.  CONSUMMATION OF THE OFFER IS CONDITIONED (THE "RIGHTS
CONDITION") UPON THE RIGHTS HAVING BEEN REDEEMED BY THE BOARD OF DIRECTORS OF
THE COMPANY OR THE PURCHASER BEING SATISFIED, IN ITS SOLE DISCRETION, THAT THE
RIGHTS HAVE BEEN INVALIDATED OR ARE INAPPLICABLE TO THE OFFER AND THE PROPOSED
MERGER. THE RIGHTS ARE DESCRIBED IN THE COMPANY'S REGISTRATION STATEMENT ON FORM
8-A, DATED DECEMBER 21, 1988, AS AMENDED (THE "COMPANY 8-A"), AND A SUMMARY
DESCRIPTION IS PROVIDED BELOW AND IN SECTION 11. THE FOLLOWING SUMMARY IS BASED
ON INFORMATION CONTAINED IN THE COMPANY 8-A.
 
    The Rights Agreement provides that, until the close of business on the
Distribution Date (as defined in Section 11), the Rights will be represented by
and transferred with the associated Shares. Until the Distribution Date (or
earlier redemption or expiration of the Rights), the surrender for transfer of
any certificates representing the Shares will constitute the transfer of the
Rights associated with the Shares represented by such certificate. The Rights
Agreement further provides that, following the Distribution Date, the Rights
become exercisable, and separate certificates evidencing the Rights ("Rights
Certificates") will be mailed to the holders of record of the outstanding
Shares.
 
    The Rights Agreement provides that, at any time prior to the close of
business on the earliest of (i) the tenth business day after the first public
announcement that a person has become an Acquiring Person (as defined in Section
11), (ii) the date an Acquisition Event (as defined in Section 11) has occurred
and (iii) the Final Expiration Date (as defined in Section 11), the Board of
Directors of the Company may direct the Company to redeem the Rights in whole,
but not in part, at a price of $.01 per Right (except as provided in the Rights
Agreement).
 
    Based on publicly available information, the Purchaser believes that, as of
February 17, 1998, the Rights were not exercisable, Rights Certificates had not
been issued and the Rights were evidenced by the
 
                                       3
<PAGE>
Shares. The Purchaser believes that, as a result of the commencement of the
Offer on February 17, 1998, the Distribution Date may occur as early as March 3,
1998, unless prior to such date the Company's Board of Directors redeems the
Rights or takes action to delay the Distribution Date. The Distribution Date may
also occur sooner. See Section 11.
 
    THE CONTROL SHARE CONDITION.  CONSUMMATION OF THE OFFER IS CONDITIONED (THE
"CONTROL SHARE CONDITION") UPON THE PURCHASER BEING SATISFIED, IN ITS SOLE
DISCRETION, THAT SECTIONS 78.378 THROUGH 78.3793 OF THE NEVADA LAW (THE "NEVADA
CONTROL SHARE ACQUISITION STATUTE") ARE INAPPLICABLE TO THE OFFER AND THE
PROPOSED MERGER.
 
    Pursuant to the Nevada Control Share Acquisition Statute, an "acquiring
person," who acquires a "controlling interest" in an "issuing corporation," may
not exercise voting rights as to any "control shares" unless such voting rights
are conferred by a majority vote of the disinterested stockholders of the
issuing corporation at a meeting of such stockholders. In the event that the
control shares are accorded full voting rights and the acquiring person acquires
control shares with a majority or more of all the voting power, any stockholder,
other than the acquiring person, who does not vote in favor of authorizing
voting rights for the control shares, is entitled to demand payment for the fair
value of such stockholder's shares, and the corporation must comply with the
demand. For purposes of the provisions under this subsection, "acquiring person"
means any person who, individually or in association with others, acquires or
offers to acquire, directly or indirectly, the ownership of outstanding voting
shares of an issuing corporation sufficient to enable the acquiring person,
individually or in association with others, directly or indirectly, to exercise
(i) one-fifth or more but less than one-third, (ii) one-third or more but less
than a majority and/or (iii) a majority or more of the voting power of the
issuing corporation in the election of directors. Voting rights must be
conferred by a majority of the outstanding voting shares of disinterested
stockholders as each threshold is reached and/or exceeded.
 
    "Control shares" means those outstanding voting shares of an issuing
corporation which an acquiring person acquires or offers to acquire in an
acquisition or within 90 days immediately preceding the date when the acquiring
person became an acquiring person. "Issuing corporation" means a corporation
that is organized in Nevada, has 200 or more stockholders (at least 100 of whom
are stockholders of record and residents of Nevada) and does business in Nevada
directly or through an affiliated corporation.
 
    The above provisions do not apply if, prior to the acquisition, the articles
of incorporation or bylaws of the Company to be in effect on the tenth day
following the acquisition of a controlling interest by an acquiring person
provide that said provisions do not apply. The Company's Restated Articles of
Incorporation, as amended (the "Articles"), and its Bylaws currently do not
exclude the Company from the restrictions imposed by such provisions. The
Control Share Condition would be satisfied if, prior to the acquisition, the
Bylaws were amended such that, on the tenth day following consummation of the
Offer, the Bylaws provide that the provisions of the Nevada Control Share
Acquisition Statute do not apply, or if the Purchaser, in its sole discretion,
were satisfied that the Nevada Control Share Acquisition Statute was invalid or
its restrictions were otherwise inapplicable to the Purchaser in connection with
the Offer and the Proposed Merger for any reason, including, without limitation,
those specified in the Nevada Control Share Acquisition Statute.
 
    THE BUSINESS COMBINATION CONDITION.  CONSUMMATION OF THE OFFER IS
CONDITIONED (THE "BUSINESS COMBINATION CONDITION") UPON THE PURCHASER BEING
SATISFIED, IN ITS SOLE DISCRETION, THAT SECTIONS 78.411 THROUGH 78.444 OF THE
NEVADA LAW (THE "NEVADA BUSINESS COMBINATION STATUTE") ARE INAPPLICABLE TO THE
PURCHASER IN CONNECTION WITH THE OFFER AND THE PROPOSED MERGER.
 
    The Nevada Business Combination Statute restricts the ability of a "resident
domestic corporation" to engage in any combination with an "interested
stockholder" for three years following the date on which the interested
stockholder acquired the shares that caused such stockholder to become an
interested
 
                                       4
<PAGE>
stockholder, unless the combination or the purchase of shares by the interested
stockholder on the date on which the interested stockholder acquired the shares
that caused such stockholder to become an interested stockholder is approved by
the board of directors of the resident domestic corporation before that date.
 
    If the combination was not previously approved, the interested stockholder
may effect a combination after the three-year period only if such stockholder
receives approval from a majority of the disinterested shares or the offer meets
certain fair price criteria.
 
    For purposes of the above provisions, "resident domestic corporation" means
a Nevada corporation that has 200 or more stockholders. "Interested stockholder"
means any person, other than the resident domestic corporation or its
subsidiaries, who is (i) the beneficial owner, directly or indirectly, of 10% or
more of the voting power of the outstanding voting shares of the resident
domestic corporation or (ii) an affiliate or associate of the resident domestic
corporation and, at any time within three years immediately before the date in
question was the beneficial owner, directly or indirectly, of 10% or more of the
voting power of the then outstanding shares of the resident domestic
corporation. The above provisions do not apply to corporations that so elect in
their articles of incorporation or in a charter amendment approved by a majority
of the outstanding voting shares of disinterested stockholders. Such a charter
amendment, however, would not become effective for 18 months after its passage
and could apply only to stock acquisitions occurring after its effective date.
The Articles do not exclude the Company from the restrictions imposed by such
provisions.
 
    The Business Combination Condition would be satisfied if the Company's Board
of Directors approved the Offer and the Proposed Merger prior to consummation of
the Offer and the Proposed Merger or if the Purchaser, in its sole discretion,
were satisfied that the Nevada Business Combination Statute was invalid or its
restrictions were otherwise inapplicable to the Purchaser in connection with the
Offer and the Proposed Merger for any reason, including, without limitation,
those specified in the Nevada Business Combination Statute.
 
    Certain other conditions to the consummation of the Offer are described in
Section 14. The Purchaser expressly reserves the right, in its sole discretion,
to waive any one or more of the conditions to the Offer. See Sections 14 and 15.
 
    THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

                                THE TENDER OFFER
 
    1.  TERMS OF THE OFFER.  Upon the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and conditions
of any such extension or amendment), the Purchaser will accept for payment and
thereby purchase all Shares validly tendered and not withdrawn in accordance
with the procedures set forth in Section 4 on or prior to the Expiration Date.
The term "Expiration Date" means 12:00 Midnight, New York City time, on Monday,
March 16, 1998, unless and until the Purchaser, in its sole discretion, shall
have extended the period of time for which the Offer is open, in which event the
term "Expiration Date" shall mean the time and date at which the Offer, as so
extended by the Purchaser, shall expire.
 
    The Purchaser expressly reserves the right, in its sole discretion, at any
time and from time to time, to extend the period during which the Offer is open
for any reason, including the occurrence of any of the events specified in
Section 14, by giving oral or written notice of such extension to the
Depositary. During any such extension, all Shares previously tendered and not
withdrawn will remain subject to the Offer and subject to the right of a
tendering stockholder to withdraw such stockholder's Shares. See Section 4.
 
    Subject to the applicable regulations of the Commission, the Purchaser also
expressly reserves the right, in its sole discretion, at any time or from time
to time, to (i) delay acceptance for payment of or, regardless of whether such
Shares were theretofore accepted for payment, payment for any Shares pending
receipt of any regulatory or governmental approvals specified in Section 15,
(ii) terminate the Offer (whether or not any Shares have theretofore been
accepted for payment) if any condition referred to in Section 14 has not been
satisfied or upon the occurrence of any event specified in Section 14 and (iii)
waive any condition or otherwise amend the Offer in any respect, in each case,
by giving oral or written notice of such delay, termination, waiver or amendment
to the Depositary and, other than in the case of any such waiver, by making a
public announcement thereof. The Purchaser acknowledges that (i) Rule 14e-1(c)
under the Exchange Act requires the Purchaser to pay the consideration offered
or return the Shares tendered promptly after the termination or withdrawal of
the Offer and (ii) the Purchaser may not delay acceptance for payment of, or
payment for (except as provided in clause (i) of the preceding sentence), any
Shares upon the occurrence of any event specified in Section 14 without
extending the period of time during which the Offer is open.
 
    The rights reserved by the Purchaser in the preceding paragraph are in
addition to the Purchaser's rights pursuant to Section 14. Any such extension,
delay, termination or amendment will be followed as promptly as practicable by
public announcement thereof, and such announcement in the case of an extension
will be made no later than 9:00 a.m., New York City time, on the next business
day after the previously scheduled Expiration Date. Without limiting the manner
in which the Purchaser may choose to make any public announcement, subject to
applicable law (including Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange
Act, which require that material changes be promptly disseminated to holders of
Shares), the Purchaser shall have no obligation to publish, advertise or
otherwise communicate any such public announcement other than by issuing a press
release or other public announcement.
 
    If the Purchaser makes a material change in the terms of the Offer, or if it
waives a material condition to the Offer, the Purchaser will extend the Offer
and disseminate additional tender offer materials to the extent required by
Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. The minimum period
during which an offer must remain open following material changes in the terms
of the offer, other than a change in price or a change in percentage of
securities sought or a change in any dealer's soliciting fee, will depend upon
the facts and circumstances, including the relative materiality, of the changes.
With respect to a change in price or a change in the percentage of securities
sought, a minimum period of 10 business days is generally required to allow for
adequate dissemination and investor response. For purposes of the Offer, a
"business day" means any day other than a Saturday, Sunday or a federal holiday
and consists of the time period from 12:01 a.m. through 12:00 Midnight, New York
City time.

    Unless and until the Purchaser declares that the Rights Condition is
satisfied, stockholders will be required to tender one associated Right for each
Share tendered to effect a valid tender of such Share. See Sections 3 and 11.
 
    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OF THE
MINIMUM CONDITION, THE RIGHTS CONDITION, THE CONTROL SHARE CONDITION AND THE
BUSINESS COMBINATION CONDITION AND THE EXPIRATION OR TERMINATION OF ALL WAITING
PERIODS IMPOSED BY THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976, AS
AMENDED, AND THE REGULATIONS THEREUNDER (THE "HSR ACT"), AND THE SATISFACTION OF
THE OTHER CONDITIONS SET FORTH IN SECTION 14. The Purchaser reserves the right
(but shall not be obligated), in accordance with applicable rules and
regulations of the Commission, to waive any or all of such conditions. If, by
the Expiration Date, any or all of such conditions have not been satisfied, the
Purchaser may, in its sole discretion, elect to (i) extend the Offer and,
subject to applicable withdrawal rights, retain all tendered Shares until the
expiration of the Offer, as extended, subject to the terms of the Offer, (ii)
waive all of the unsatisfied conditions and, subject to complying with
applicable rules and regulations of the Commission, accept for payment all
Shares so tendered and not extend the Offer or (iii) terminate the Offer and not
accept for payment any Shares and return all tendered Shares to tendering
stockholders. In the event that the Purchaser waives any condition set forth in
Section 14, the Commission may, if the waiver is deemed to constitute a material
change to the information previously provided to the stockholders, require that
the Offer remain open for an additional period of time and/or that the Purchaser
disseminate information concerning such waiver.
 
    Requests are being made to the Company pursuant to Rule 14d-5 under the
Exchange Act for the use of the Company's stockholder list, its list of holders
of Rights and security position listings for the purpose of disseminating the
Offer to holders of Shares. Upon compliance by the Company with such request,
this Offer to Purchase and the related Letter of Transmittal and, if required,
other relevant materials will be mailed to record holders of Shares and Rights
and will be furnished to brokers, dealers, commercial banks, trust companies and
similar persons whose names, or the names of whose nominees, appear on the
stockholder list and list of holders of Rights, if applicable, or who are listed
as participants in a clearing agency's security position listing for subsequent
transmittal to beneficial owners of Shares and Rights. A request under Nevada
Law for the Company's stockholder list is also being made to the Company.
 
    2.  ACCEPTANCE FOR PAYMENT AND PAYMENT.  Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of the Offer as so extended or amended), the Purchaser will
purchase, by accepting for payment, and will pay for, all Shares validly
tendered and not withdrawn (as permitted by Section 4) prior to the Expiration
Date promptly after the later to occur of (i) the Expiration Date and (ii) the
satisfaction or waiver of the conditions to the Offer set forth in Section 14.
In addition, subject to applicable rules of the Commission, the Purchaser
expressly reserves the right to delay acceptance for payment of, or payment for,
Shares pending receipt of any regulatory or governmental approvals specified in
Section 15.
 
    For information with respect to approvals required to be obtained prior to
the consummation of the Offer, including under the HSR Act and the European
Community Regulation 4064/89 (the "EC Merger Regulation"), see Section 15.
 
    In all cases, payment for Shares purchased pursuant to the Offer will be
made only after timely receipt by the Depositary of (i) certificates evidencing
such Shares ("Share Certificates") and, if applicable, Rights Certificates for
the associated Rights, or, in the case of Shares, timely confirmation (a
"Book-Entry Confirmation") of the book-entry transfer of such Shares and, if
applicable, Rights, into the Depositary's account at The Depository Trust
Company or Philadelphia Depository Trust Company (collectively, the "Book-Entry
Transfer Facilities") pursuant to the procedures set forth in Section 3, (ii)
the Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, with any required signature
 
                                       7
<PAGE>
guarantees, or an Agent's Message (as defined below) in connection with a
book-entry transfer and (iii) any other documents required by the Letter of
Transmittal.
 
    The term "Agent's Message" means a message transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares and, if applicable, the Rights which are
the subject of such Book-Entry Confirmation that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against such participant.
 
    Unless and until the Purchaser declares that the Rights Condition is
satisfied, if rights certificates have been distributed to holders of Shares,
such holders are required to tender, or make book-entry transfer of, Rights
Certificates representing a number of Rights equal to the number of Shares being
tendered in order to effect a valid tender of such Shares.
 
    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not withdrawn as, if
and when the Purchaser gives oral or written notice to the Depositary of the
Purchaser's acceptance of such Shares for payment pursuant to the Offer. In all
cases, upon the terms and subject to the conditions of the Offer, payment for
Shares purchased pursuant to the Offer will be made by deposit of the purchase
price therefor with the Depositary, which will act as agent for tendering
stockholders for the purpose of receiving payment from the Purchaser and
transmitting payment to validly tendering stockholders. UNDER NO CIRCUMSTANCES
WILL INTEREST ON THE PURCHASE PRICE FOR SHARES BE PAID BY THE PURCHASER. If, for
any reason whatsoever, acceptance for payment of or payment for any Shares and
Rights tendered pursuant to the Offer is delayed, or the Purchaser is unable to
accept for payment or pay for Shares and Rights tendered pursuant to the Offer,
then, without prejudice to the Purchaser's rights set forth herein, the
Depositary may, nevertheless, on behalf of the Purchaser and subject to Rule
14e-1(c) under the Exchange Act, retain tendered Shares and Rights and such
Shares and Rights may not be withdrawn except to the extent that the tendering
stockholder is entitled to and duly exercises withdrawal rights as described in
Section 4.
 
    If any tendered Shares are not accepted for payment for any reason or if
Share Certificates are submitted representing more Shares than are tendered,
Share Certificates representing unpurchased or untendered Shares will be
returned, without expense to the tendering stockholder (or, in the case of
Shares delivered by book-entry transfer into the Depositary's account at a
Book-Entry Transfer Facility pursuant to the procedures set forth in Section 3,
such Shares will be credited to an account maintained within such Book-Entry
Transfer Facility), in each case with the Rights Certificates, if any, as
promptly as practicable following the expiration, termination or withdrawal of
the Offer.
 
    IF, PRIOR TO THE EXPIRATION DATE, THE PURCHASER SHALL INCREASE THE
CONSIDERATION OFFERED TO HOLDERS OF SHARES PURSUANT TO THE OFFER, SUCH INCREASED
CONSIDERATION SHALL BE PAID TO ALL HOLDERS OF SHARES THAT ARE PURCHASED PURSUANT
TO THE OFFER, WHETHER OR NOT SUCH SHARES WERE TENDERED PRIOR TO SUCH INCREASE IN
CONSIDERATION.
 
    The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to one or more of the Purchaser's subsidiaries or
affiliates the right to purchase all or any portion of the Shares and Rights
tendered pursuant to the Offer, but any such transfer or assignment will not
relieve the Purchaser of its obligations under the Offer or prejudice the rights
of tendering stockholders to receive payment for Shares validly tendered and
accepted for payment pursuant to the Offer.

    3.  PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES AND RIGHTS.
 
VALID TENDER OF SHARES AND RIGHTS
 
    Except as set forth below, in order for Shares and (prior to the
Distribution Date) Rights to be validly tendered pursuant to the Offer, the
Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, together with any required signature guarantees, or an Agent's Message
in connection with a book-entry delivery of Shares and (prior to the
Distribution Date) Rights, and any other documents required by the Letter of
Transmittal must be received by the Depositary at one of its addresses set forth
on the back cover of this Offer to Purchase on or prior to the Expiration Date
and either (i) Share Certificates and, if applicable, Rights Certificates
representing tendered Shares and Rights must be received by the Depositary, or
such Shares and Rights must be tendered pursuant to the procedure for book-entry
transfer set forth below and Book-Entry Confirmation must be received by the
Depositary, in each case on or prior to the Expiration Date, or (ii) the
guaranteed delivery procedures set forth below must be complied with.
 
    IF THE PURCHASER DECLARES THAT THE RIGHTS CONDITION IS SATISFIED, THE
PURCHASER WILL NOT REQUIRE DELIVERY OF RIGHTS. UNLESS AND UNTIL THE PURCHASER
DECLARES THAT THE RIGHTS CONDITION IS SATISFIED, HOLDERS OF SHARES WILL BE
REQUIRED TO TENDER ONE ASSOCIATED RIGHT FOR EACH SHARE TENDERED IN ORDER TO
EFFECT A VALID TENDER OF SUCH SHARE.
 
    THE METHOD OF DELIVERY OF SHARE CERTIFICATES, RIGHTS CERTIFICATES (IF
APPLICABLE), THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT
THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
SEPARATE DELIVERY OF RIGHTS CERTIFICATES
 
    If the Distribution Date has not occurred prior to the Expiration Date, a
tender of Shares will also constitute a tender of the associated Rights. If the
Distribution Date has occurred and Rights Certificates are distributed by the
Company to holders of Shares prior to the time a holder's Shares are tendered
pursuant to the Offer, in order for Rights (and the corresponding Shares) to be
validly tendered, Rights Certificates representing a number of Rights equal to
the number of Shares tendered must be delivered to the Depositary or, if
available, a Book-Entry Confirmation received by the Depositary with respect
thereto. If the Distribution Date has occurred and Rights Certificates are not
distributed prior to the time Shares are tendered pursuant to the Offer, Rights
may be tendered prior to a stockholder receiving Rights Certificates by use of
the guaranteed delivery procedure described below. In any case, a tender of
Shares constitutes an agreement by the tendering stockholder to deliver Rights
Certificates representing a number of Rights equal to the number of Shares
tendered pursuant to the Offer to the Depositary within three business days
after the date Rights Certificates are distributed. The Purchaser reserves the
right to require that the Depositary receive Rights Certificates, or a
Book-Entry Confirmation, if available, with respect to such Rights, prior to
accepting the related Shares for payment pursuant to the Offer if the
Distribution Date has occurred prior to the Expiration Date.
 
BOOK-ENTRY TRANSFER
 
    The Depositary will make a request to establish accounts with respect to the
Shares at each of the Book-Entry Transfer Facilities for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any financial
institution that is a participant in the system of any Book-Entry Transfer
 
                                       9
<PAGE>
Facility may make Book-Entry delivery of Shares by causing such Book-Entry
Transfer Facility to transfer such Shares into the Depositary's account at such
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for such transfer. However, although delivery of Shares
may be effected through book-entry transfer into the Depositary's account at a
Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees, or
an Agent's Message in connection with a book-entry transfer, and any other
required documents must, in any case, be transmitted to and received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase on or prior to the Expiration Date, or the guaranteed delivery
procedure set forth below must be complied with.
 
    If the Distribution Date occurs, to the extent that the Rights become
eligible for book-entry transfer under procedures established by a particular
Book-Entry Transfer Facility, the Depositary will also make a request to
establish an account with respect to the Rights at each of the Book-Entry
Transfer Facilities. No assurance can be given that book-entry delivery of
Rights will be available. If book-entry delivery of Rights is available, the
foregoing book-entry transfer procedures will also apply to Rights. Otherwise,
if Rights Certificates have been issued, a tendering stockholder will be
required to tender Rights by means of physical delivery to the Depositary of
Rights Certificates (in which event references in this Offer to Purchase to
Book-Entry Confirmations with respect to Rights will be inapplicable) or
pursuant to the guaranteed delivery procedure set forth below.
 
    DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH
SUCH BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO
THE DEPOSITARY.
 
SIGNATURE GUARANTEES
 
    Signatures on all Letters of Transmittal must be guaranteed by a firm that
is a bank, broker, dealer, credit union, savings association or other entity
which is a member in good standing of the Securities Transfer Agents Medallion
Program (an "Eligible Institution"), unless the Shares and Rights tendered
thereby are tendered (i) by a registered holder of Shares and Rights who has not
completed either the box labeled "Special Payment Instructions" or the box
labeled "Special Delivery Instructions" on the Letter of Transmittal or (ii) for
the account of an Eligible Institution. See Instruction 1 of the Letter of
Transmittal.
 
    If the Share Certificates or Rights Certificates are registered in the name
of a person other than the signer of the Letter of Transmittal, or if payment is
to be made to, or Share Certificates or Rights Certificates for unpurchased
Shares or Rights are to be issued or returned to, a person other than the
registered holder, then the tendered certificates must be endorsed or
accompanied by appropriate stock powers, signed exactly as the name or names of
the registered holder or holders appear on such certificates, with the
signatures on the certificates or stock powers guaranteed by an Eligible
Institution as provided in the appropriate Letter of Transmittal. See
Instructions 1 and 5 of the Letter of Transmittal.
 
    If the Share Certificates and Rights Certificates are forwarded separately
to the Depositary, a properly completed and duly executed appropriate Letter of
Transmittal (or facsimile thereof) must accompany each such delivery.
 
                                       10
<PAGE>
GUARANTEED DELIVERY
 
    If a stockholder desires to tender Shares and Rights pursuant to the Offer
and such stockholder's Share Certificates or, if applicable, Rights Certificates
are not immediately available (including, if the Distribution Date has occurred,
because Rights Certificates have not yet been distributed by the Company) or
time will not permit all required documents to reach the Depositary on or prior
to the Expiration Date, or, in the case of Shares, the procedures for book-entry
transfer cannot be completed on a timely basis, such Shares or Rights may
nevertheless be tendered if all of the following guaranteed delivery procedures
are duly complied with:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form made available by the Purchaser, is received by the
Depositary, as provided below, on or prior to the Expiration Date; and
 
    (iii) the Share Certificates and Rights Certificates (or a Book-Entry
Confirmation) representing all tendered Shares and Rights, in proper form for
transfer together with a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), with any required signature guarantees (or,
in the case of a book-entry transfer, an Agent's Message) and any other
documents required by the Letter of Transmittal are received by the Depositary
within (x) in the case of Shares, three New York Stock Exchange, Inc. ("NYSE")
trading days after the date of execution of such Notice of Guaranteed Delivery
or (y) in the case of Rights, a period ending on the later of (1) three NYSE
trading days after the date of execution of such Notice of Guaranteed Delivery
and (2) three business days after the date Rights Certificates are distributed
to stockholders by the Company.
 
    The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by facsimile transmission to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in such Notice of
Guaranteed Delivery.
 
    Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of Share Certificates for, or of Book-Entry
Confirmation with respect to, such Shares, and if the Distribution Date has
occurred, Rights Certificates for, or a Book-Entry Confirmation, if available,
with respect to, the associated Rights (unless the Purchaser elects, in its sole
discretion, to make payment for such Shares pending receipt of the Rights
Certificates for, or a Book-Entry Confirmation with respect to, such Rights), a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), together with any required signature guarantees (or, in the case of a
book-entry transfer, Rights, an Agent's Message) and any other documents
required by the Letter of Transmittal. Accordingly, payment might not be made to
all tendering stockholders at the same time, and will depend upon when Share
Certificates (or Rights Certificates) are received by the Depositary or
Book-Entry Confirmations of the Shares (or Rights, if available) are received
into the Depositary's account at a Book-Entry Transfer Facility.
 
    If the Rights Condition is satisfied, the guaranteed delivery procedure with
respect to Rights Certificates and the requirement for the tender of Rights will
no longer apply.
 
BACKUP FEDERAL INCOME TAX WITHHOLDING
 
    UNDER THE BACKUP FEDERAL INCOME TAX WITHHOLDING APPLICABLE TO CERTAIN
STOCKHOLDERS (OTHER THAN CERTAIN EXEMPT STOCKHOLDERS, INCLUDING, AMONG OTHERS,
ALL CORPORATIONS AND CERTAIN FOREIGN INDIVIDUALS), THE DEPOSITARY MAY BE
REQUIRED TO WITHHOLD 31% OF THE AMOUNT OF ANY PAYMENTS MADE TO SUCH STOCKHOLDERS
PURSUANT TO THE OFFER. TO PREVENT
 
                                       11
<PAGE>
BACKUP FEDERAL INCOME TAX WITHHOLDING, EACH SUCH STOCKHOLDER MUST PROVIDE THE
DEPOSITARY WITH SUCH STOCKHOLDER'S CORRECT TAXPAYER IDENTIFICATION NUMBER AND
CERTIFY THAT SUCH STOCKHOLDER IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX
WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF
TRANSMITTAL. SEE INSTRUCTION 9 OF THE LETTER OF TRANSMITTAL.
 
APPOINTMENT AS PROXY
 
    By executing the Letter of Transmittal, a tendering stockholder irrevocably
appoints designees of the Purchaser, and each of them, as such stockholder's
attorneys-in-fact and proxies, with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of such stockholder's
rights with respect to the Shares and, if applicable, Rights tendered by such
stockholder and accepted for payment by the Purchaser and with respect to any
and all other Shares or Rights and other securities or rights issued or issuable
in respect of such Shares and Rights on or after the date of this Offer to
Purchase. All such powers of attorney and proxies shall be considered
irrevocable and coupled with an interest in the tendered Shares and Rights. Such
appointment will be effective upon the acceptance for payment of such Shares and
Rights by the Purchaser in accordance with the terms of the Offer. Upon such
acceptance for payment, all other powers of attorney and proxies given by such
stockholder with respect to such Shares, Rights, and such other securities or
rights prior to such payment will be revoked, without further action, and no
subsequent powers of attorney and proxies may be given by such stockholder (and,
if given, will not be deemed effective). The designees of the Purchaser will,
with respect to the Shares and Rights and such other securities and rights for
which such appointment is effective, be empowered to exercise all voting and
other rights of such stockholder as they in their sole discretion may deem
proper at any annual or special meeting of the Company's stockholders, or any
adjournment or postponement thereof, or by consent in lieu of any such meeting
or otherwise. In order for Shares and Rights to be deemed validly tendered,
immediately upon the acceptance for payment of such Shares and Rights, the
Purchaser or its designee must be able to exercise full voting rights with
respect to such Shares, Rights and other securities, including voting at any
meeting of stockholders.
 
DETERMINATION OF VALIDITY
 
    All questions as to the form of documents and the validity, eligibility
(including time of receipt) and acceptance for payment of any tender of Shares
or Rights will be determined by the Purchaser, in its sole discretion, whose
determination shall be final and binding on all parties. The Purchaser reserves
the absolute right to reject any or all tenders determined by it not to be in
proper form or the acceptance of or payment for which may, in the opinion of the
Purchaser's counsel, be unlawful. The Purchaser also reserves the absolute
right, in its sole discretion, to waive any of the conditions of the Offer or
any defect or irregularity in any tender of Shares or Rights of any particular
stockholder whether or not similar defects or irregularities are waived in the
case of other stockholders.
 
    The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letter of Transmittal and the instructions thereto) will be final
and binding. No tender of Shares or Rights will be deemed to have been validly
made until all defects and irregularities with respect to such tender have been
cured or waived by the Purchaser. None of the Purchaser or any of its affiliates
or assigns, the Dealer Manager, the Depositary, the Information Agent or any
other person or entity will be under any duty to give any notification of any
defects or irregularities in tenders or incur any liability for failure to give
any such notification.
 
    The Purchaser's acceptance for payment of Shares and, if applicable, Rights
tendered pursuant to any of the procedures described above will constitute a
binding agreement between the tendering stockholder and the Purchaser upon the
terms and subject to the conditions of the Offer.
 
                                       12
<PAGE>
    4. WITHDRAWAL RIGHTS.  Except as otherwise provided in this Section 4,
tenders of Shares and Rights made pursuant to the Offer are irrevocable. Shares
and Rights tendered pursuant to the Offer may be withdrawn at any time on or
prior to the Expiration Date and, unless theretofore accepted for payment as
provided herein, may also be withdrawn at any time after April 17, 1998 (or such
later date as may apply in case the Offer is extended). A withdrawal of Shares
will also constitute a withdrawal of the associated Rights. Rights may not be
withdrawn unless the associated Shares are also withdrawn.
 
    If, for any reason whatsoever, acceptance for payment of any Shares and
Rights tendered pursuant to the Offer is delayed, or the Purchaser is unable to
accept for payment or pay for Shares and Rights tendered pursuant to the Offer,
then, without prejudice to the Purchaser's rights set forth herein, the
Depositary may, nevertheless, on behalf of the Purchaser and subject to Rule
14e-1(c) under the Exchange Act, retain tendered Shares and Rights and such
Shares and Rights may not be withdrawn except to the extent that the tendering
stockholder is entitled to and duly exercises withdrawal rights as described in
this Section 4. Any such delay will be by an extension of the Offer to the
extent required by law.
 
    For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Depositary at one of its addresses
set forth on the back cover of this Offer to Purchase. Any such notice of
withdrawal must specify the name of the person who tendered the Shares and
Rights to be withdrawn, the number of Shares and Rights to be withdrawn, and (if
Share Certificates and Rights Certificates have been tendered) the name of the
registered holder of the Shares and Rights as set forth in the Share Certificate
and Rights Certificate, if different from that of the person who tendered such
Shares and Rights. If Share Certificates and Rights Certificates have been
delivered or otherwise identified to the Depositary, then prior to the physical
release of such certificates, the tendering stockholder must submit the serial
numbers shown on the particular certificates evidencing the Shares and Rights to
be withdrawn and the signature on the notice of withdrawal must be guaranteed by
an Eligible Institution, except in the case of Shares and Rights tendered for
the account of an Eligible Institution. If Shares and Rights have been tendered
pursuant to the procedures for book-entry transfer set forth in Section 3, the
notice of withdrawal must specify the name and number of the account at the
appropriate Book-Entry Transfer Facility to be credited with the withdrawn
Shares and Rights, in which case a notice of withdrawal will be effective if
delivered to the Depositary by any method of delivery described in the first
sentence of this paragraph. Withdrawals of Shares and Rights may not be
rescinded. Any Shares and Rights properly withdrawn will be deemed not validly
tendered for purposes of the Offer, but may be retendered at any subsequent time
prior to the Expiration Date by following any of the procedures described in
Section 3.
 
    All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination shall be final and binding. None of the
Purchaser or any of its affiliates or assigns, the Dealer Manager, the
Depositary, the Information Agent or any other person or entity will be under
any duty to give any notification of any defects or irregularities in any notice
of withdrawal or incur any liability for failure to give any such notification.
 
    5. CERTAIN UNITED STATES TAX CONSEQUENCES.  The receipt of cash for Shares
pursuant to the Offer or the Proposed Merger will be a taxable transaction for
federal income tax purposes and may also be a taxable transaction under
applicable state, local, foreign and other tax laws. For federal income tax
purposes, each selling stockholder would generally recognize gain or loss equal
to the difference between the amount of cash received and such stockholder's
adjusted tax basis for the sold Shares (together with the Rights). Such gain or
loss will be capital gain or loss (assuming the Shares are held as a capital
asset) and any such capital gain or loss will be long term if, as of the date of
sale, the Shares were held for more than one year or will be short term if, as
of such date, the Shares were held for one year or less. For individuals and
certain other non-corporate taxpayers, there is also a mid-term holding period
of more than one year, but not more than 18 months.
 
                                       13
<PAGE>
    For United States federal income tax purposes, it is unclear whether amounts
received with respect to the redemption of Rights by the Company should be
treated as additional consideration for the Shares or as a dividend or other
ordinary income or as capital gain.
 
    The foregoing discussion may not be applicable to certain stockholders of
the Company, including persons who acquired Shares pursuant to the exercise of
employee stock options or otherwise as compensation, individuals who are not
citizens or residents of the United States and foreign corporations, persons
holding Shares in a straddle, hedging, or conversion transaction, and entities
that are otherwise subject to special tax treatment (such as broker-dealers,
insurance companies, tax-exempt organizations, financial institutions and
passthrough entities).
 
    Unless a stockholder complies with certain reporting and/or certification
procedures or is an exempt recipient under applicable provisions of the Code and
Treasury Regulations, such stockholder may be subject to withholding tax of 31%
with respect to any cash payments received pursuant to the Offer or the Proposed
Merger. Stockholders should consult their brokers or the Depositary to ensure
compliance with such procedures. Foreign stockholders should consult with their
own tax advisors regarding withholding taxes in general.
 
    THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND IS BASED ON THE CODE AND TREASURY REGULATIONS
CURRENTLY IN FORCE WHICH MAY BE AMENDED AT ANY TIME, POSSIBLY WITH RETROACTIVE
EFFECT. EACH STOCKHOLDER IS URGED TO CONSULT SUCH STOCKHOLDER'S TAX ADVISOR WITH
RESPECT TO THE TAX CONSEQUENCES TO SUCH STOCKHOLDER OF THE OFFER AND PROPOSED
MERGER, INCLUDING FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES.
 
    6. PRICE RANGE OF THE SHARES; DIVIDENDS.  The Shares are listed and traded
on the NYSE under the symbol "CSC." The following table sets forth, for the
periods indicated, the reported high and low sales prices for the Shares on the
NYSE.

    On December 17, 1997, the last trading day prior to the date on which
Computer Associates commenced discussions with the Company regarding a potential
business combination, the last reported sale price on the NYSE for the Shares
was $81 5/8. On February 13, 1998, the last trading day prior to the
commencement of the Offer on February 17, 1998, the last reported sale price on
the NYSE for the Shares was $107 3/8. STOCKHOLDERS ARE URGED TO OBTAIN A CURRENT
MARKET QUOTATION FOR THE SHARES.
 
                                       14
<PAGE>
    According to the 1997 10-K and the December 1997 10-Q, the Company did not
declare or pay any cash dividends on the Shares during fiscal 1996 or 1997 or
during the first three quarters of fiscal 1998.
 
    The Purchaser believes, based upon publicly available information, that as
of the date of this Offer to Purchase, the Rights are listed on the NYSE and all
Rights are attached to the associated Shares and are not traded separately. As a
result, the sale prices per Share set forth above are also the high and low sale
prices per Share and associated Right during all such periods. Upon the
occurrence of the Distribution Date, the Rights are to detach, and may trade
separately, from the Shares. See Section 11. The Purchaser believes that, as a
result of the commencement of the Offer on February 17, 1998, the Distribution
Date may occur as early as March 3, 1998, unless prior to such date the
Company's Board of Directors redeems the Rights or takes action to delay the
Distribution Date. The Distribution Date may also occur sooner. See Section 11.
IF THE DISTRIBUTION DATE OCCURS AND THE RIGHTS BEGIN TO TRADE SEPARATELY FROM
THE SHARES, STOCKHOLDERS ARE ALSO URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR
THE RIGHTS.
 
    7. POSSIBLE EFFECTS OF THE OFFER ON THE MARKET FOR THE SHARES; STOCK
EXCHANGE LISTING; EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS.
 
POSSIBLE EFFECTS OF THE OFFER ON THE MARKET FOR THE SHARES
 
    The purchase of Shares pursuant to the Offer will reduce the number of
Shares that might otherwise trade publicly and could adversely affect the
liquidity and market value of the remaining Shares held by the public. The
purchase of Shares pursuant to the Offer can also be expected to reduce the
number of holders of Shares. The Purchaser cannot predict whether the reduction
in the number of Shares that might otherwise trade publicly would have an
adverse or beneficial effect on the market price for or marketability of the
Shares or whether it would cause future market prices to be greater or less than
the Offer price therefor.
 
STOCK EXCHANGE LISTING
 
    Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the requirements for continued listing on the NYSE,
and may, therefore, be delisted from the NYSE. According to the NYSE's published
guidelines, the NYSE would consider delisting the Shares if, among other things,
the number of record holders of at least 100 Shares should fall below 1,200, the
number of publicly held Shares (exclusive of holdings of officers, directors,
their immediate families and other concentrated holdings of 10% or more ("NYSE
Excluded Holdings")) should fall below 600,000 or the aggregate market value of
publicly held Shares (exclusive of NYSE Excluded Holdings) should fall below
$5,000,000.
 
    According to the 1997 10-K, as of June 2, 1997, there were 10,947 holders of
record of Shares. If, as a result of the purchase of Shares pursuant to the
Offer or otherwise, the Shares no longer meet the requirements of the NYSE for
continued listing and the listing of the Shares is discontinued, the market and
prices for such Shares could be adversely affected.
 
    If the NYSE were to delist the Shares, it is possible that the Shares would
trade on another securities exchange or in the over-the-counter market and that
price quotations would be reported by such exchange, through the National
Association of Securities Dealers Automated Quotation System ("NASDAQ") or other
sources. Such trading and the availability of such quotations would, however,
depend upon the number of stockholders and/or the aggregate market value of the
Shares remaining at such time, the interest in maintaining a market in the
Shares on the part of securities firms, the possible termination of registration
of the Shares under the Exchange Act as described below and other factors.
 
                                       15
<PAGE>
EXCHANGE ACT REGISTRATION
 
    The Shares are currently registered under the Exchange Act. The purchase of
Shares pursuant to the Offer may result in the Shares becoming eligible for
deregistration under the Exchange Act. Registration of the Shares may be
terminated upon application by the Company to the Commission if the Shares are
not listed on a "national securities exchange" and there are fewer than 300
record holders of Shares. Termination of registration of the Shares under the
Exchange Act would substantially reduce the information required to be furnished
by the Company to its stockholders and the Commission and would make certain
provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b) and the requirements of furnishing a proxy statement
in connection with stockholders' meetings pursuant to Section 14(a) or 14(c) and
the related requirement of an annual report, no longer applicable to the
Company. If the Shares are no longer registered under the Exchange Act, the
requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions would no longer be applicable to the Company. Furthermore,
the ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144
promulgated under the Securities Act of 1933 may be impaired or, with respect to
certain persons, eliminated. If registration of the Shares under the Exchange
Act were terminated, the Shares would no longer be "margin securities" or
eligible for stock exchange listing or NASDAQ reporting. The Purchaser intends
to seek to cause the Company to terminate the registration of the Shares as soon
after the consummation of the Offer or Proposed Merger as the requirements for
termination of registration are met.
 
    Based upon publicly available information, the Purchaser believes that, as
of the date of this Offer to Purchase, the Rights are registered under the
Exchange Act and are listed on the NYSE, but are attached to the Shares and are
not separately transferable. The Purchaser believes that, as a result of the
commencement of the Offer on February 17, 1998, the Distribution Date may occur
as early as March 3, 1998, unless prior to such date the Company's Board of
Directors redeems the Rights or takes action to delay the Distribution Date. The
Distribution Date may also occur sooner. See Section 11. The Rights Agreement
provides that, following the Distribution Date, certificates evidencing the
Rights will be sent to all holders of Rights and Rights will become transferable
apart from the Shares. See Section 11. If the Distribution Date occurs and the
Rights separate from the Shares, the foregoing discussion with respect to the
effect of the Offer on the market for the Shares, stock exchange listings and
Exchange Act registration would apply to the Rights in a similar manner.
 
MARGIN REGULATIONS
 
    The Shares are currently "margin securities" under the regulations of the
Board of Governors of the Federal Reserve System, which has the effect, among
other things, of allowing brokers to extend credit on the collateral of such
Shares. Depending upon factors similar to those described above regarding
listing and market quotations, it is possible that, following the Offer, the
Shares would no longer constitute "margin securities" for the purposes of the
margin regulations of the Federal Reserve Board and therefore could no longer be
used as collateral for loans made by brokers.

(1) Computer Associates incurred certain after-tax charges against earnings in
    connection with its acquisitions of Cheyenne Software, Inc. in fiscal 1997,
    Legent Corporation in fiscal 1996 and The ASK Group, Inc. in fiscal 1995.
    Had these charges not been taken, Computer Associates' net income for fiscal
    1997, 1996 and 1995 would have been $964 million, $752 million and $586

    10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY. Computer Associates
and the Company are parties to license agreements pursuant to which the Company
licenses Computer Associates software for internal use and for third party
processing on behalf of the Company's clients, and are parties to other
arrangements under which the Company has the right to resell Computer Associates
software. Representatives of Computer Associates and the Company have met from
time to time over the past several years to discuss technical and marketing
aspects of these arrangements.
 
    Early in the week of December 15, 1997, Sanjay Kumar, President and Chief
Operating Officer of Computer Associates, telephoned the office of Van
Honeycutt, Chairman and Chief Executive Officer of the Company, to arrange a
meeting to discuss a possible business combination between the companies. On
December 18, Mr. Kumar and Charles B. Wang, Chairman and Chief Executive Officer
of Computer Associates, met with Mr. Honeycutt at Mr. Honeycutt's office in El
Segundo, California to discuss the merits of combining Computer Associates and
the Company. Mr. Honeycutt agreed to review the idea and get back to Computer
Associates.

<PAGE>
    On or about January 9, 1998, Mr. Honeycutt called Mr. Kumar. Mr. Kumar and
Mr. Honeycutt discussed a number of issues relating to a business combination,
including possible synergies of a transaction. They agreed to meet in early
February to continue the discussions. On January 19 and 20, the Computer
Associates Board of Directors met and considered the possible business
combination. On or about January 20, Mr. Kumar called Mr. Honeycutt to request
to have their respective financial advisors meet. Mr. Honeycutt expressed his
desire to keep the discussions between principals until a general agreement had
been reached. Following that discussion, Mr. Kumar sent Mr. Honeycutt the
following letter:
 
                                          January 21, 1998
 
    Mr. Van B. Honeycutt
    Chairman
    CSC
    2100 East Grand Avenue
    El Segundo, CA 90245
 
    Dear Van:
 
        I appreciate your candid views of the merits of combining our two
    companies, as well as the appreciating value of CSC. While you and I have
    some differences over valuation and the synergies of the combined companies,
    I continue to believe that a merger would benefit both companies and our
    collective shareholders tremendously. Computer Associates Board of Directors
    has unanimously supported our negotiation of this transaction. Your
    shareholders would receive a substantial premium to market value, and we are
    confident that they would be pleased with our offer.
 
        We for a long time have held the strategic view that the strengths of
    our company's software products and development capabilities should be
    combined with a provider of strategic management consulting and information
    technology services. More and more we are seeing the industry moving toward
    this view. Such a combination is highly complementary to both companies, in
    our case adding strategic consulting and integration services to our strong
    group of products and in your case gaining access to a large pool of
    products and one of the best stables of new software developers. As year
    2000 approaches, our combined enterprise should lead the technology world
    into the 21st century.
 
        I look forward to our February 5, 1998 meeting to discuss on-going
    management and continue our discussions of other issues. In the interim, I
    am requesting that you reconsider having our mutual advisors and a limited
    group of senior management further our due diligence. In this way, we both
    can be informed by the facts, and in a position to move quickly before any
    notice of our discussions becomes generally known.
 
        Again, congratulations on CSC's 3rd Quarter results. I am traveling for
    the next few days, but can be reached through my office or by confidential
    fax.
 
                                          Sincerely,
                                          /s/ Sanjay Kumar
                                          Sanjay Kumar
                                          President and
                                          Chief Operating Officer
 
    On January 21 and 23, Computer Associates through a wholly owned subsidiary
bought 170,000 Shares.
 
                                       21
<PAGE>
    On January 27, Mr. Honeycutt advised Mr. Kumar that he did not want to
engage advisors in the process until after the February 5 meeting. On February
2, Mr. Honeycutt called Mr. Kumar to suggest that the February 5 meeting cover
several significant issues and Mr. Honeycutt agreed to travel to Scottsdale,
Arizona to accommodate Mr. Wang's schedule so that he could also participate in
the discussions.
 
    Mr. Honeycutt met with Mr. Wang and Mr. Kumar in Scottsdale, Arizona on
February 5. At that meeting, Mr. Honeycutt raised several issues, including
organization, employee retention, stock options, severance plans, board
composition and valuation. Messrs. Wang and Kumar addressed all of the issues
with Mr. Honeycutt, reaching agreement on all points other than board
composition and valuation. On February 6, Mr. Kumar and Mr. Honeycutt discussed
value and compensation issues and Mr. Honeycutt's role in a combined
organization. After discussing Mr. Honeycutt's range of values for the Company,
Mr. Kumar offered to begin immediate negotiations. After Mr. Honeycutt declined,
he agreed that he and Mr. Kumar would speak further on February 10. Mr. Kumar
sent the following letter summarizing his understanding of the discussions from
the meeting:
 
                                          February 6, 1998
 
    Mr. Van B. Honeycutt
    Chairman and CEO
    CSC
    2100 East Grand Avenue
    El Segundo, CA 90245
    Dear Van:
 
        Thank you for taking the time yesterday to meet with Charles and me in
    Scottsdale and for our telephone conversation of today. I found the
    discussions beneficial but remain disappointed that we were unable to reach
    agreement on price.
 
        As we have discussed since our first meeting on this subject in
    December, we believe that the combination of CA and CSC would create a world
    class information technology solution provider with unparalleled depth in
    both software and services. The combination of CA 's people and CA 's
    software product strength together with CSC's people and CSC's services
    capability would create the perfect model for the next generation of
    information technology solutions provider that will lead our industry into
    the next millennium.
 
        In reviewing our discussions of yesterday, it is apparent that we are in
    agreement on all points with the exception of price. To confirm our views on
    a number of the key issues you raised yesterday:
 
       - We are in agreement on the need and manner of retaining key managers
         and employees. We would supply key managers and employees with
         employment agreements that will provide them with a strong incentive to
         remain with the combined company.
 
       - We are in agreement on providing stock option grants, consistent with
         CA 's prior practice for our own employees, to key managers and
         employees. This will allow them to participate in the success of the
         combined company, and will further ensure continuity with respect to
         the combined company's commitment to our mutual clients.
 
       - We are in agreement that the CSC organization within the combined
         company will be on equal footing to CA's existing product organization.
         I am committed to making sure that all of the members of the CSC
         organization are welcomed into the combined company with open arms.
 
                                       22
<PAGE>
       - We do not expect the combined company to have to reduce any headcount
         to achieve the synergies that a transaction of this size demands.
         Consequently, as in our last major acquisition of Cheyenne Software, we
         anticipate that all of the valuable CSC employees will be offered
         positions with the combined company.
 
       - Beyond the absolute level of staffing, we expect to maintain the
         current structure of CSC's organization with little change. As we
         discussed, it would make sense for the CA part of the combined company
         to take over CSC's product development efforts and for CSC, in turn, to
         take over CA's service commitments and efforts. The inherent synergies
         in this process will allow both the CA and CSC parts of the combined
         company to do what they do best.
 
       - We expect to staff new projects with both outside hiring and some
         redeployment of existing CA staff. This will allow the combined company
         to aggressively seek new services opportunities.
 
        Given all of the points of agreement, I remain confident that the
    employees of both CA and CSC will embrace this combination. Our mutual
    clients would also be excited by the possibility of being serviced by a
    stronger and broader information technology solutions provider. The industry
    and the market will clearly applaud such a combination.
 
        With respect to CSC's shareholders, I remain confident that they would
    find CA 's proposal of an all cash offer of $100 very attractive. At our
    offer, CSC's shareholders would be receiving a premium of approximately 30%
    to the average closing price for the month of December, when we first
    initiated discussions regarding a combination of our respective businesses.
    We have expressed our concern that knowledge of our discussions might be
    contributing to the recent rise in your stock price, to an all time high
    during the last week. Even so, our proposed offer still yields a significant
    premium. Any analysis of our proposed offer must consider the recent run up
    in your stock price.
 
        A transaction would be subject, among other things, to receipt of any
    required regulatory approvals and third-party consents and the taking of all
    necessary actions to eliminate the applicability of, or to satisfy, any
    anti-takeover or other defensive provisions contained in the applicable
    corporate statues or CSC's charter and by-laws including CSC's poison pill.
    As I mentioned to you yesterday, we have made financing arrangements to
    facilitate a rapid conclusion. The Board of Directors, key senior
    management, and I have discussed this transaction in detail, and we are all
    excited about the possibilities of creating a world class combination of CA
    and CSC. Our proposal remains subject to the approval of our Board of
    Directors.
 
        Van, I hope that CSC's Board of Directors and you share our enthusiasm
    for this transaction. We view our offer as an excellent opportunity for the
    shareholders of CSC to realize full value for their holdings, and equally
    importantly we view our offer as a tremendous opportunity for CSC's
    employees and clients. We are prepared to enter into immediate negotiations
    with your directors, management, advisors and you to answer any additional
    questions that you may have regarding our proposal. As I mentioned to you
    yesterday and today, we would prefer a negotiated transaction that can be
    presented to your shareholders as a joint product of CA 's and CSC's Boards
    of Directors and management. In this spirit, we would be willing to consider
    some adjustment to our offer based on the outcome of our due diligence
    reviews and discussions. I look forward to hearing from you at your earliest
    convenience.
 
                                          Sincerely,
                                          /s/ Sanjay Kumar
                                          Sanjay Kumar
                                          President and
                                          Chief Operating Officer

    On February 10, after not having received any response to the February 6
letter, Mr. Kumar contacted Mr. Honeycutt to advise him that the Computer
Associates Board of Directors had unanimously approved an offer to acquire the
Company. Mr. Kumar also discussed Mr. Honeycutt's continuing role in the
Company, and had further discussions on value. Mr. Kumar suggested that the
parties immediately begin negotiations to bridge the gap on value with a view to
quickly concluding a negotiated transaction. After Mr. Honeycutt declined, Mr.
Kumar sent to Mr. Honeycutt the following letter:
 
                                          February 10, 1998
 
    Mr. Van B. Honeycutt
    Chairman and CEO
    Computer Sciences Corporation
    2100 East Grand Avenue
    El Segundo, CA 90245
    Dear Van,
 
        Charles and I appreciate the significant time you have invested over the
    last few months in the discussions that we have had regarding the
    combination of Computer Associates International, Inc. ("CA") and Computer
    Sciences Corporation ("CSC"). However, we are disappointed that CA and CSC
    have not been able to come to a final resolution.
 
        Consequently, we are writing to offer to acquire CSC in a merger
    transaction in which your stockholders would receive $108 in cash for each
    share of CSC common stock. We believe our offer presents an extremely
    attractive opportunity for your stockholders, at a price which represents a
    premium of nearly 35% over the closing price of CSC's common stock on the
    day we commenced our discussions in mid-December. At that time, CSC's stock
    was trading close to its all-time high.
 
        The CA Board of Directors has unanimously approved this offer. Further,
    as I have previously informed you, CA has obtained the necessary financing
    commitments to consummate this transaction without delay. As we agreed, the
    combination of CA and CSC would create a world-class information technology
    solutions provider with unparalleled depth in both software and services.
    The combination of CA's strength in software and CSC's services
    capabilities, together with our collective personnel, would create the
    perfect model for the next generation of information technology solutions
    provider that will lead our industry into the millennium.
 
        As we discussed at our meeting on February 5, and as confirmed by my
    letter of February 6:
 
       - We are in agreement on the need and manner of retaining key managers
         and employees. We would supply key managers and employees with
         employment agreements that will provide them with a strong incentive to
         remain with the combined company.
 
       - We are in agreement on providing stock option grants to key managers
         and employees. This will allow them to participate in the success of
         the combined company, and will further ensure continuity with respect
         to the combined company's commitment to our mutual clients.
 
       - We are in agreement that the CSC organization within the combined
         company will be on equal footing to CA's existing product organization.
         CA is committed to making sure that all of the members of the CSC
         organization are welcomed into the combined company with open arms.
 
       - We do not expect the combined company to need to reduce any headcount
         to achieve the synergies that a transaction of this size demands.
         Consequently, as in our last major acquisition
 
                                       24
<PAGE>
         of Cheyenne Software, we anticipate that all of the valuable CSC
         employees will be offered positions with the combined company.
 
       - Beyond the absolute level of staffing, we expect to maintain the
         current structure of CSC's organization with little change. As we
         discussed, it would make sense for the CA part of the combined company
         to take over CSC's product development efforts and for CSC, in turn, to
         take over CA's service commitments and efforts. The inherent synergies
         in this process will allow both the CA and CSC parts of the combined
         company to do what they do best.
 
       - We expect to staff new projects with both outside hiring and some
         redeployment of existing CA staff. This will allow the combined company
         to aggressively seek new services opportunities.
 
        As we have previously discussed, we have conducted an extensive analysis
    of CSC based on publicly available information. We believe that CA and CSC
    may be able to bridge some of our differences with respect to valuation if
    CA is given the opportunity to conduct limited due diligence on CSC's
    business and operations. With CSC's cooperation, our due diligence review
    can be accomplished within a week.
 
        Our offer is subject to the execution of a mutually satisfactory merger
    agreement containing customary terms and conditions. We believe that such an
    agreement can be negotiated while we are conducting our due diligence review
    of CSC. Our counsel has advised us that an acquisition of CSC by CA should
    not encounter regulatory delays.
 
        We look forward to meeting with you to discuss our offer. We are hopeful
    your Board will conclude that your stockholders should not be denied the
    opportunity to consider our offer. We at CA are determined to take every
    appropriate action to pursue this transaction. In view of the importance of
    this matter, time is of the essence, and we await your prompt response.
 
                                          Sincerely,
                                          /s/ Sanjay Kumar

    Mr. Kumar attempted to reach Mr. Honeycutt on February 11 and 12 without
success. On February 14 and 15, at Mr. Kumar's request, Mr. Michael Urfirer of
Bear, Stearns & Co., Inc., Computer Associates' financial advisor, discussed
with Gene Sykes of Goldman Sachs & Co., financial advisor to the Company,
Computer Associates' strong desire to make every effort to consummate a
friendly, negotiated transaction. Mr. Urfirer also advised Mr. Sykes that
Computer Associates believed that the value of a negotiated transaction would be
$114 per Share, the increased price reflecting the difference in value between a
friendly and a contested transaction. Mr. Urfirer offered to arrange a meeting
between the principals to attempt to reach agreement on valuation, which was
declined. Following these discussions, Mr. Kumar sent the following letter to
Mr. Honeycutt.

    Mr.Van B. Honeycutt
    Chairman and CEO
    Computer Sciences Corporation
    2100 East Grand Avenue
    El Segundo, CA 90245
    Dear Van:
 
        We have been disappointed by the response to date to the offer that we
    made last Tuesday to combine our two companies' businesses by means of a
    cash merger at $108 per CSC share. As we have expressed from the beginning,
    our hope and intent was to prompt a meaningful effort to move ahead on both
    our parts to a negotiated transaction.
 
        We believe that the best way, by far, to effect a combination of our two
    companies' businesses is through prompt negotiation of the terms followed by
    equally prompt implementation. Every one of CSC's constituencies --
    shareholders, employees, customers and partners -- will greatly benefit from
    this approach.
 
        We made it clear in our February 10th letter that we believed that we
    could bridge some of our differences with respect to value in a friendly
    transaction. The value of a friendly, promptly negotiated and concluded
    transaction is substantial in our view. Our financial advisor, Michael
    Urfirer of Bear Stearns, has communicated to your financial advisor, Gene
    Sykes of Goldman Sachs, in very specific terms the magnitude of the value
    increase to your shareholders in a negotiated transaction.
 
        Conversely, an adverse impact to CSC's business and people,
    substantially increased difficulty in combining the businesses and
    significant costs to both companies are inevitable outcomes of a contested
    process, which would result in a reduced value of CSC. In short, we are
    proposing a transaction that has compelling value to your shareholders and
    other constituencies, especially when measured against a contested
    alternative.
 
        Our request is simple. We would like to commence negotiations with you
    this weekend. We would be guided in those negotiations by the thinking
    reflected in my letters of February 6 and 10, which remains unchanged,
    except as to price. I very much look forward to this. We are committed to
    the business strategy of combining our two companies' businesses and, as I
    have stated, believe a negotiated transaction is clearly preferable for all
    concerned. However, as we communicated to Mr. Sykes earlier today, if
    substantive negotiations have not started by Monday at 12:00 noon EST, we
    will have no choice but to move ahead on a unilateral basis at a
    substantially lower price than we communicated to Mr. Sykes which would be
    required to reflect the diminution in value as indicated above.
 
        We hope this demonstrates our continuing efforts to consummate a
    friendly transaction. It is truly important to us that you and your Board
    are fully informed at this critical stage.
 
                                       26

        I look forward to hearing from you. I can be reached at the numbers I

    Mr. Urfirer attempted to reach Mr. Sykes on February 16 without success.
 
    On February 17, 1998, Computer Associates commenced the Offer.
 
    In addition, on February 17, 1998, Computer Associates filed the Complaint
in the United States District Court for the District of Nevada. The Complaint
requests that the Company be enjoined from taking actions to impede the exercise
of the shareholder franchise, or the consummation of the Offer, and that the
Company be required to render inapplicable various anti-takeover devices
including its Rights Agreement, so that the Offer may be consummated.
 
    The Complaint also seeks various declarations pursuant to the Nevada Law and
the Bylaws regarding the Solicitation. Computer Associates has asked the Court
to declare that the holders of a majority of the Shares may act, by written
consent or vote, to amend the Bylaws. Computer Associates also has asked the
Court to declare that the holders of two-thirds of the Shares may act, by
written consent or vote, to remove a sufficient number of the existing directors
to be able to designate a majority of the members of the Company's Board of
Directors. Computer Associates has moved the Court for an expedited
determination of these issues. That motion is pending before the Court.
 
    Also, on February 17, 1998, with respect to the Solicitation, Computer
Associates filed preliminary copies of solicitation materials with the
Commission.
 
    11. PURPOSE OF THE OFFER AND THE PROPOSED MERGER; PLANS FOR THE COMPANY.
 
    PURPOSE OF THE OFFER AND THE PROPOSED MERGER.  The purpose of the Offer and
the Proposed Merger is to enable Computer Associates to acquire control of, and
the entire equity interest in, the Company. The Offer, as the first step in the
acquisition of the Company, is intended to facilitate the acquisition of all the
Shares. Computer Associates currently intends, as soon as practicable following
consummation of the Offer, to propose and seek to consummate the Proposed
Merger. The purpose of the Proposed Merger is to acquire all Shares not tendered
and purchased pursuant to the Offer or otherwise. Pursuant to the Proposed
Merger, each then outstanding Share (other than Shares owned by the Purchaser,
Computer Associates or any of their subsidiaries, Shares held in the treasury of
the Company and Shares owned by stockholders who perfect any available appraisal
rights under the Nevada Law) would be converted into the right to receive an
amount in cash equal to the price per Share paid pursuant to the Offer. The
timing of consummation of the Offer and the Proposed Merger will depend on a
variety of factors and legal requirements, the actions of the Company's Board of
Directors, the number of Shares (if any) acquired by the Purchaser pursuant to
the Offer, and whether the conditions to the Offer have been satisfied.
 
    Except in the case of a "short-form" merger as described below, under the
Nevada Law, the approval of the Company's Board of Directors and the affirmative
vote of holders of a majority of the outstanding Shares (including any Shares
owned by the Purchaser and its affiliates) would be required to approve the
Proposed Merger. If the Purchaser acquires, through the Offer or otherwise,
voting power with respect to at least a majority of the outstanding Shares which
would be the case if the Minimum Condition and the Control Share Condition were
satisfied and the Purchaser were to accept for payment Shares tendered pursuant
to the Offer, it would have sufficient voting power to effect the Proposed
Merger without the vote
 
                                       27
<PAGE>
of any other stockholder of the Company. If, following the consummation of the
Offer, the current members of the Board of Directors of the Company have not
previously been removed pursuant to the Solicitation and do not either resign or
cause nominees of Computer Associates to be elected to fill the resulting
vacancies or approve the Proposed Merger, then the Purchaser intends to act by
written consent to remove the members of the Board of Directors and to cause
nominees of the Purchaser to be elected to fill the resulting vacancies who,
subject to the fiduciary duties they would have as directors of the Company,
intend to approve the Proposed Merger; amend the Rights Agreement or redeem the
Rights if possible, or otherwise act to ensure that the Rights Condition is
satisfied; satisfy the Control Share Condition, if applicable; satisfy the
Business Combination Condition, if applicable; and take any other actions
necessary to permit the Offer and the Proposed Merger to be consummated.
 
    The Nevada Law also provides that if a parent company owns at least 90% of
each class of stock of a subsidiary, the parent company can effect a
"short-form" merger with that subsidiary without a stockholder vote.
Accordingly, if, as a result of the Offer or otherwise, the Purchaser acquires
or controls the voting power of at least 90% of the outstanding Shares, the
Purchaser could, and intends to, effect the Proposed Merger without prior notice
to, or any action by, any other stockholder of the Company.
 
    If the Proposed Merger has not been consummated, the Purchaser or an
affiliate of the Purchaser may, either immediately following the consummation or
termination of the Offer (whether or not the Purchaser purchases Shares pursuant
to the Offer), or from time to time thereafter, seek to acquire additional
Shares through open market purchases, privately negotiated transactions, a
tender offer or exchange offer or otherwise, upon such terms and at such prices
as it may determine, which may be more or less than the price to be paid
pursuant to the Offer. Alternatively, the Purchaser and its affiliates reserve
the right to sell or otherwise dispose of any or all of the Shares acquired by
them pursuant to the Offer or otherwise, upon such terms and at such prices as
they shall determine.
 
    The precise timing and other details of any merger or other business
combination transaction will depend on a variety of factors such as general
economic conditions and prospects, the future prospects, asset value and
earnings of the Company, the number of Shares acquired by the Purchaser pursuant
to the Offer or otherwise and the statutory requirements described above. The
Purchaser can give no assurance that a merger or other business combination will
be proposed or that, if it is proposed, it will not be delayed or abandoned. The
Purchaser expressly reserves the right not to propose any merger or similar
business combination involving the Company, or to propose a merger or other
business combination on terms other than those set forth herein, and its
ultimate decision could be affected by information hereafter obtained by the
Purchaser, changes in general economic or market conditions or in the business
of the Company or other factors.
 
    The making of the Offer will enable the Purchaser to commence the process of
seeking regulatory approvals for its acquisition of the Company. See Section 15.
In addition, by tendering Shares pursuant to the Offer, the Company's
stockholders effectively will be given the opportunity to express to the
Company's Board that they wish to be able to accept the Offer and to approve the
Proposed Merger or a similar transaction with Computer Associates.
 
    THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF A PROXY, CONSENT OR
AUTHORIZATION FOR OR WITH RESPECT TO THE ANNUAL MEETING OR ANY SPECIAL MEETING
OF THE COMPANY'S STOCKHOLDERS. ANY SUCH SOLICITATION WHICH COMPUTER ASSOCIATES
OR THE PURCHASER MAY MAKE WILL BE MADE ONLY PURSUANT TO SEPARATE SOLICITATION
MATERIALS COMPLYING WITH ALL APPLICABLE REQUIREMENTS OF SECTION 14(a) OF THE
EXCHANGE ACT AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER.
 
    PLANS FOR THE COMPANY.  Upon the consummation of the Offer and the Proposed
Merger, Computer Associates expects that it will offer all of the valuable
employees of the Company positions with the combined company and expects to
maintain the current structure of the Company's organization with little change.
However, Computer Associates intends to conduct a review of the Company and its
assets,
 
                                       28
<PAGE>
corporate structure, dividend policy, capitalization, operations, properties and
policies and to consider what, if any, changes would be desirable in light of
the circumstances then existing, and reserves the right to take such actions or
effect such changes as it deems desirable. See Section 10.
 
    Except as described in this Offer to Purchase, the Purchaser has no present
plans or proposals that would relate to or would result in (i) an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any of its subsidiaries, (ii) a sale or transfer of a
material amount of assets of the Company or any of its subsidiaries, (iii) any
change in the present Board of Directors or management of the Company, (iv) any
material changes in the present capitalization or dividend policy of the
Company, (v) any other material change in the Company's corporate structure or
business, (vi) causing a class of securities of the Company to be delisted from
a national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association or
(vii) a class of equity securities of the Company becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Exchange Act.
 
    APPRAISAL RIGHTS AND "GOING-PRIVATE" TRANSACTIONS.  Upon consummation of the
Proposed Merger, if, as of the record date fixed to determine the stockholders
of the Company entitled to receive notice of and to vote at the meeting of
stockholders of the Company to act upon the Proposed Merger, shares of Common
Stock are either (i) listed on a national securities exchange or designated as a
national market system security on an interdealer quotation system by the
National Association of Securities Dealers, Inc. (the "NASD") or (ii) held of
record by more than 2,000 holders, holders of Shares who do not vote in favor of
the Proposed Merger and who comply with applicable statutory procedures under
the Nevada Law may be entitled to receive a judicial determination and payment
of the "fair value" (excluding any element of value arising from the
accomplishment or expectation of the Offer and Proposed Merger) of their Shares
(subject to certain exceptions). The value so determined could be the same as,
or more or less than, the price per Share offered pursuant to the Offer or
proposed to be paid in the Proposed Merger. The Commission has adopted Rule
13e-3 under the Exchange Act which is applicable to certain "going-private"
transactions and which may under certain circumstances be applicable to the
Proposed Merger. Rule 13e-3 would be inapplicable if (i) the Shares were
deregistered under the Exchange Act prior to the Proposed Merger or other
business combination or (ii) if holders of Shares receive only equity securities
of Parent in the Proposed Merger. If applicable, Rule 13e-3 would require, among
other things, that certain financial information concerning the Company and
certain information relating to the fairness of the Proposed Merger and the
consideration offered to minority stockholders be filed with the Commission and
distributed to minority stockholders before the consummation of any such
transaction.
 
    THE RIGHTS.  Set forth below is a summary description of the Rights derived
from the Company 8-A.
 
    On December 21, 1988, the Company's Board of Directors authorized and
declared a dividend distribution of one Right for each outstanding Share of the
Company. Each Right entitles the registered holder to purchase from the Company
one four-thousandth (1/4000) of a share of Series A Junior Participating
Preferred Stock, $1.00 par value (the "Series A Preferred Stock"), of the
Company at a purchase price of $78.33 (the "Exercise Price"), subject to
adjustment.
 
    The Rights will not be transferable apart from the Shares until the earlier
of (i) the close of business on the tenth business day after a public
announcement that a person or group (other than a Company or certain related
entities), has become the beneficial owner of 20% or more of the Shares (an
"Acquiring Person") or (ii) the close of business on the tenth business day
after the date that a tender offer or an exchange offer is first published or
sent or given within the meaning of Rule 14d-2 under the Exchange Act, the
consummation of which would result in a person or group (other than a Company or
certain related entities) beneficially owning at least 30% of the outstanding
Shares (the earlier of the dates specified in clauses (i) and (ii) being the
"Distribution Date"). Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any certificates
representing the Shares will constitute the transfer of the Rights associated
with the Shares represented by such certificate.
 
                                       29
<PAGE>
Following the Distribution Date, the Rights become exercisable, and separate
certificates evidencing the Rights will be mailed to the holders of record of
the outstanding Shares.
 
    The Rights will expire on December 21, 1998 (the "Final Expiration Date"),
unless the Rights are earlier redeemed by the Company as described below.
 
    The Rights Agreement provides that, in the event that on or after the first
date of public announcement by the Company or an Acquiring Person that an
Acquiring Person has become such (the "Stock Acquisition Date"), the Company is
acquired in a merger or other business combination transaction or 50% or more of
its consolidated assets or earning power are sold in one or a series of
transactions (other than the ordinary course of business) (each, an "Acquisition
Event"), proper provision will be made so that each holder of a Right, other
than Rights beneficially owned by the Acquiring Person and certain related
entities (which will thereafter be void), will thereafter have the right to
receive, upon the exercise thereof at a price equal to the then current Exercise
Price, shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times such Exercise Price.
 
    The Rights Agreement provides that, from and after the close of business on
the tenth business day following the Stock Acquisition Date, proper provision
will be made so that each holder of a Right, other than Rights beneficially
owned by the Acquiring Person and certain related entities (which will
thereafter be void), will thereafter have the right to receive upon exercise one
Share at an exercise price of 10% of the then current market value of the
Shares. If the Company does not have sufficient Shares available for all Rights
to be exercised, the Company shall substitute for all or any portion of the
Shares that would otherwise be issuable upon the exercise of the Rights, cash,
assets or other securities or any combination of the foregoing having the same
aggregate value as such Shares.
 
    The Rights Agreement provides that, at any time prior to the close of
business on the earliest of (i) the tenth business day after the Stock
Acquisition Date, (ii) the date an Acquisition Event has occurred, and (iii) the
Final Expiration Date, the Board of Directors of the Company may direct the
Company to redeem the Rights in whole, but not in part, at a redemption price of
$.01 per Right (the "Redemption Price"). Promptly upon the action of the Board
electing to redeem the Rights, the Company is to make announcement thereof, and
from and after the date of such election by the Board of Directors of the
Company to redeem the Rights, the right to exercise the Rights will terminate,
and the only right of holders of Rights will be to receive the Redemption Price
per Right.
 
    The Rights Agreement provides that the terms of the Rights may be amended by
the Board of Directors of the Company in any manner (including to shorten or
lengthen any time period such as the redemption period) at any time prior to the
close of business on the earliest of (i) the tenth business day after the Stock
Acquisition Date, (ii) the date an Acquisition Event has occurred, and (iii) the
Final Expiration Date. Thereafter, the terms of the Rights may be amended by the
Company's Board of Directors in any manner so long as such amendment does not
adversely affect the interests of the holders of Rights (other than the
Acquiring Person and certain related entities). Notwithstanding the foregoing,
no amendment may be made which changes the redemption price or the Final
Expiration Date.
 
    The foregoing summary of the Rights Agreement does not purport to be
complete and is qualified in its entirety by reference to the Company 8-A and
the text of the Rights Agreement as set forth as an exhibit thereto, filed with
the Commission, copies of which may be obtained in the manner set forth in
Section 8.
 
    If the Rights Condition is not satisfied and the Purchaser elects, in its
sole discretion, to waive the Rights Condition and consummate the Offer, and if
there are outstanding Rights which have not been acquired by the Purchaser, the
Purchaser will evaluate its alternatives. Such alternatives could include
purchasing additional Rights in the open market, in privately negotiated
transactions, in another tender or exchange offer or otherwise. Any such
additional purchase of Rights could be for cash or other consideration. Under
such circumstances, the Proposed Merger might be delayed or abandoned as
impracticable. The form and amount of consideration to be received by the
holders of Shares in the Proposed Merger, if consummated, might be subject to
adjustment to compensate the Purchaser for, among other things, the
 
                                       30
<PAGE>
costs of acquiring Rights and a portion of the potential dilution cost to the
Purchaser of Rights not owned by the Purchaser and its wholly owned subsidiaries
at the time of the Proposed Merger. In such event, the consideration paid for
Shares in the Proposed Merger could be substantially less than the consideration
paid in the Offer. In addition, the Purchaser may elect under such circumstances
not to consummate the Proposed Merger.
 
    UNLESS AND UNTIL THE PURCHASER DECLARES THAT THE RIGHTS CONDITION IS
SATISFIED, STOCKHOLDERS WILL BE REQUIRED TO TENDER ONE ASSOCIATED RIGHT FOR EACH
SHARE TENDERED IN ORDER TO EFFECT A VALID TENDER OF SUCH SHARE. IF THE
DISTRIBUTION DATE DOES NOT OCCUR PRIOR TO THE EXPIRATION DATE, A TENDER OF
SHARES WILL ALSO CONSTITUTE A TENDER OF THE ASSOCIATED RIGHTS. SEE SECTIONS 1
AND 3.
 
    12. SOURCE AND AMOUNT OF FUNDS.  The total amount of funds required by the
Purchaser to purchase all of the outstanding Shares, refinance certain
outstanding indebtedness of Computer Associates and its subsidiaries and the
Company and its subsidiaries, and pay related fees and expenses is expected to
be approximately $11.7 billion. The Purchaser will obtain such funds from
Computer Associates by means of capital contributions, loans or a combination
thereof, and Computer Associates will, in turn, obtain such funds through
borrowings from commercial banks, other financial institutions and institutional
investors and from its general corporate funds. The Purchaser has not
conditioned the Offer on obtaining financing.
 
    Computer Associates has received a commitment letter dated February 15, 1998
(the "Commitment Letter") from Credit Suisse First Boston ("CSFB"), Bank of
America National Trust & Savings Association, The Chase Manhattan Bank and
NationsBank, N.A. (collectively, the "Underwriters"), pursuant to which the
Underwriters have committed to provide, on specified terms and subject to
specified conditions, up to $10.0 billion in senior credit facilities (the
"Credit Facilities") to Computer Associates. CSFB has agreed to provide up to
$2.8 billion of the Credit Facilities and will act as the Administrative Agent
(the "Administrative Agent") and Arranger for the Credit Facilities; and each of
the other Underwriters has agreed to provide up to $2.4 billion of the Credit
Facilities. Although the Underwriters have committed to provide all of the
Credit Facilities, the Underwriters expect to act as syndication agents for a
syndicate of commercial banks and financial institutions, which, together with
the Underwriters, will provide the Credit Facilities.
 
    The Commitment Letter contemplates three credit facilities: (i) a 1 1/2 year
senior term loan facility in the amount of $3.0 billion (the "Interim
Facility"), (ii) a 5 year senior term loan facility in the amount of $4.5
billion (the "Tranche A Facility", and together with the Interim Facility, the
"Term Loan Facilities") and (iii) a 5 year senior revolving credit facility in
the amount of $2.5 billion (the "Revolving Credit Facility"). The Revolving
Credit Facility and the Term Loan Facilities together comprise the Credit
Facilities. The proceeds of the Credit Facilities may be used (i) to finance the
Offer and the Proposed Merger, (ii) to refinance certain outstanding
indebtedness of Computer Associates and its subsidiaries including, after giving
effect to the consummation of the Offer and the Proposed Merger (together, the
"Transaction"), the Company and its subsidiaries, (iii) to pay fees and expenses
relating thereto, and (iv) in the case of the Revolving Credit Facility, for
working capital and other general corporate purposes.
 
    The Interim Facility will be available in two drawings, each of which will
be repayable in full in a single installment 18 months after the date upon which
the definitive documentation with respect to the Credit Facilities becomes
effective (the "Effective Date"). The Tranche A Facility will also be available
in two drawings, each of which will amortize in quarterly installments over a
five year period ending on the fifth anniversary of the Effective Date. The
Revolving Credit Facility will be available on a revolving basis throughout a
five year term commencing on the Effective Date and ending on the fifth
anniversary thereof. The loans under the Credit Facilities shall bear interest
(at Computer Associates' option) at specified spreads (adjusted based on the
ratings of Computer Associates' senior unsecured long-term debt) over (i) the
London interbank offered rate (adjusted for reserves) (the "Eurodollar Rate") or
(ii) the higher of (x) the CSFB base lending rate and (y) the federal funds rate
plus a margin of 0.5% (the "Base Rate").
 
                                       31
<PAGE>
Initially, the spreads will be 1 3/4% in the case of loans bearing interest with
reference to the Eurodollar Rate and 3/4% in the case of loans bearing interest
with reference to the Base Rate. The Credit Facilities will be guaranteed by
certain material subsidiaries of Computer Associates and are required to be
reduced with 100% of the net proceeds of certain asset sales, debt issues, and
equity issues by Computer Associates or its subsidiaries.
 
    The Underwriters' commitments to provide the Credit Facilities is subject to
satisfaction of certain customary conditions, including (a) absence of any
material change in or material disruption of financial, banking or capital
market conditions that, in the judgment of the Underwriters, could materially
impair the syndication of the Credit Facilities, (b) absence of any material
adverse condition or material adverse change in or affecting, or material
adverse information with respect to, the business, operations, property,
condition (financial or otherwise) or prospects of Computer Associates and its
subsidiaries taken as a whole or of the Company and its subsidiaries taken as a
whole, (c) the appropriate markets being clear of certain competing
transactions, (d) the completion by the Underwriters of, and their satisfaction
with, a due diligence investigation of publicly available information with
respect to the Company and its subsidiaries (it being understood that such due
diligence condition shall have been deemed satisfied unless any of the
Underwriters shall have notified Computer Associates in writing to the contrary
by no later than 5:00 p.m. (New York time) on February 24, 1998), (e) the
negotiation, execution and delivery prior to April 30, 1998 of definitive
documentation with respect to the Credit Facilities satisfactory to the
Underwriters and their counsel and (f) the occurrence of the initial borrowings
under the Term Loan Facilities on or before the date which is 180 days after the
earlier of (i) such execution and delivery and (ii) the commencement of the
Offer.
 
    In addition, the Commitment Letter provides that initial advances under the
Credit Facilities will be conditioned upon, among other things, (i) the
consummation of the Offer pursuant to the terms of this Offer to Purchase (as
the same may be modified from time to time in such manner as could not
reasonably be expected to be materially adverse to the rights or interests of
the Administrative Agent or the lenders), (ii) all governmental and third party
approvals necessary or reasonably requested by the Administrative Agent in
connection with the Offer, the Proposed Merger, the Credit Facilities and the
continuing operations of Computer Associates and its subsidiaries (after giving
effect to the Transaction) having been obtained and being in full force and
effect, with all waiting periods provided by applicable law having expired
without there being taken or threatened by any competent authority any action
which could reasonably be expected to restrain, prevent or otherwise impose
material adverse conditions on the Transaction (including the consummation of
the Proposed Merger) or the financing thereof, (iii) the Rights or any other
"poison pill" rights of the Company having been redeemed by the Board of
Directors of the Company or the lenders being satisfied that they have been
invalidated or otherwise not triggered, and (iv) Computer Associates having
arranged for the issue and sale of $2.75 billion in senior notes (or backstopped
bridge financing) on terms reasonably satisfactory to the lenders and for the
repayment and termination of certain existing credit facilities of Computer
Associates and its subsidiaries. It is a further condition precedent that, after
giving effect to the consummation of the Offer, the Purchaser shall own and
control that number of Shares as shall be necessary to permit the Purchaser to
approve the Proposed Merger without the affirmative vote or approval of any
other shareholders, and that there shall be no applicable statute or other
restriction which would prohibit, restrict or materially delay the consummation
of the Proposed Merger or which would make the consummation of the Proposed
Merger subject to material adverse conditions.
 
    The definitive documentation with respect to the Credit Facilities also will
contain representations, warranties, covenants (including a covenant that the
Proposed Merger occur within 120 days of the consummation of the Offer), events
of default and conditions customary for credit facilities of this size and type.
Computer Associates has agreed to pay certain fees to CSFB and the other
Underwriters with respect to the Commitment Letter and to the Underwriters and
the other lenders with respect to the Credit Facilities. Computer Associates
also has agreed to reimburse certain expenses of, and provide customary
 
                                       32
<PAGE>
indemnities to, CSFB and the other Underwriters in connection with the
Commitment Letter and the Underwriters and (under certain circumstances) the
other lenders in connection with the Credit Facilities.
 
    The foregoing summary of the source and amount of funds is qualified in its
entirety by reference to the text of the Commitment Letter, a copy of which is
filed as an exhibit to the Schedule 14D-1 of the Purchaser and Computer
Associates filed with the Commission in connection with the Offer (the "Schedule
14D-1") and is incorporated in this Offer to Purchase by reference and may be
inspected in the same manner as set forth with respect to the Company in Section
8. If and when definitive agreements with respect to the Credit Facilities are
executed, copies will be filed as exhibits to amendments to the Schedule 14D-1.
 
    Although no definitive plan or arrangement for repayment of borrowings under
the Credit Facilities has been made, Computer Associates anticipates such
borrowings will be repaid with internally generated funds (including, if the
Proposed Merger is accomplished, those of the Company) and from other sources
which may include the proceeds of future bank refinancings, asset sales or the
public or private sale of debt or equity securities. No decision has been made
concerning the method Computer Associates will use to repay the borrowings under
the Credit Facilities. Such decision will be made based on Computer Associates'
review from time to time of the advisability of particular actions, as well as
prevailing interest rates, financial and other economic conditions and such
other factors as Computer Associates may deem appropriate.
 
    13. DIVIDENDS AND DISTRIBUTIONS.  If, on or after February 13, 1998, the
Company should (a) split (including pursuant to the Announced Stock Split),
combine or otherwise change the Shares or its capitalization (other than by
redemption of the Rights in accordance with their terms as publicly disclosed
prior to February 13, 1998), (b) acquire or otherwise cause a reduction in the
number of outstanding Shares or other securities (other than as aforesaid) or
(c) issue or sell additional Shares (other than the issuance of Shares under
option prior to February 13, 1998, in accordance with the terms of such options
as publicly disclosed prior to February 13, 1998), shares of any other class of
capital stock, other voting securities or any securities convertible into, or
rights, warrants or options, conditional or otherwise, to acquire, any of the
foregoing, then, subject to the provisions of Section 14, the Purchaser, in its
sole discretion, may make such adjustments as it deems appropriate in the
purchase price and other terms of the Offer, including, without limitation, the
number or type of securities offered to be purchased or the number of securities
required to satisfy the Minimum Condition.
 
    If, on or after February 13, 1998, the Company should declare or pay any
cash dividend on the Shares or other distribution on the Shares (including the
Stock Split Dividend), or issue with respect to the Shares any additional
Shares, shares of any other class of capital stock, other voting securities or
any securities convertible into, or rights, warrants or options, conditional or
otherwise, to acquire, any of the foregoing, payable or distributable to
stockholders of record on a record date prior to the transfer of the Shares
purchased pursuant to the Offer to the Purchaser or its nominee or transferee on
the Company's stock transfer records, then, subject to the provisions of Section
14, (a) the purchase price of the Offer may, in the sole discretion of the
Purchaser, be reduced by the amount of any such cash dividend or cash
distribution and (b) the whole of any such noncash dividend, distribution or
issuance to be received by the tendering stockholders will (i) be received and
held by the tendering stockholders for the account of the Purchaser and will be
required to be promptly remitted and transferred by each tendering stockholder
to the Depositary for the account of the Purchaser, accompanied by appropriate
documentation of transfer, or (ii) at the direction of the Purchaser, be
exercised for the benefit of the Purchaser, in which case the proceeds of such
exercise will promptly be remitted to the Purchaser. Pending such remittance and
subject to applicable law, the Purchaser will be entitled to all rights and
privileges as owner of any such noncash dividend, distribution, issuance or
proceeds and may withhold the entire purchase price or deduct from the purchase
price the amount or value thereof, as determined by the Purchaser in its sole
discretion.
 
                                       33
<PAGE>
    UNLESS THE COMPANY RESCINDS THE ANNOUNCED STOCK SPLIT AND THE STOCK SPLIT
DIVIDEND PRIOR TO THE RECORD DATE THEREFOR AND THE PURCHASER DETERMINES, IN ITS
SOLE DISCRETION, THAT THE HOLDERS OF SHARES HAVE NO FURTHER RIGHTS WITH RESPECT
TO THE ANNOUNCED STOCK SPLIT AND THE STOCK SPLIT DIVIDEND, THE PURCHASER, IN ITS
SOLE DISCRETION, MAY MAKE SUCH ADJUSTMENTS AS IT DEEMS APPROPRIATE IN THE
PURCHASE PRICE AND OTHER TERMS OF THE OFFER, INCLUDING (WITHOUT LIMITATION) IN
THE NUMBER OF SECURITIES REQUIRED TO SATISFY THE MINIMUM CONDITION AND REQUIRING
TENDERING STOCKHOLDERS RECEIVING THE STOCK SPLIT DIVIDEND, IF ANY, TO RECEIVE
AND HOLD SUCH DIVIDEND FOR THE ACCOUNT OF THE PURCHASER AND PROMPTLY REMIT AND
TRANSFER SUCH DIVIDEND TO THE DEPOSITARY FOR THE ACCOUNT OF THE PURCHASER. IF
THE EXPIRATION DATE OCCURS PRIOR TO MARCH 23, 1998, THE PURCHASER INTENDS TO
REQUIRE TENDERING STOCKHOLDERS RECEIVING THE STOCK SPLIT DIVIDEND, IF ANY, TO
RECEIVE AND HOLD SUCH DIVIDEND FOR THE ACCOUNT OF THE PURCHASER AND PROMPTLY
REMIT AND TRANSFER SUCH DIVIDEND TO THE DEPOSITARY FOR THE ACCOUNT OF THE
PURCHASER AS A CONDITION TO A TENDER BEING VALID AND SUCH STOCKHOLDER BEING
ENTITLED TO RECEIVE PAYMENT FOR SUCH TENDERED SHARES. IN THIS EVENT, THE
PURCHASE PRICE OF $108 PER SHARE WILL NOT BE ADJUSTED. IF, HOWEVER, THE
EXPIRATION DATE OCCURS ON OR AFTER MARCH 23, 1998, THE PURCHASER ANTICIPATES
THAT THE PURCHASE PRICE FOR THE SHARES PURSUANT TO THE OFFER WILL BE ADJUSTED
FOR THE EFFECT OF THE ANNOUNCED STOCK SPLIT TO AN AMOUNT EQUAL TO $54 PER SHARE
FOR EACH SPLIT-ADJUSTED SHARE AND THAT THE MINIMUM CONDITION WILL BE DETERMINED
BY REFERENCE TO SUCH INCREASED AMOUNT OF SHARES OUTSTANDING.
 
    14. CERTAIN CONDITIONS OF THE OFFER.  Notwithstanding any other term or
provision of the Offer, the Purchaser will not be required to accept for payment
or, subject to any applicable rules and regulations of the Commission, including
Rule 14e-1(c) under the Exchange Act (relating to a bidder's obligation to pay
for or return tendered securities promptly after the termination or withdrawal

    series of capital stock of the Company (including the Shares), through the

    acquire beneficial ownership of more than 5% of any class or series of
    capital stock of the Company (including the Shares), other than acquisitions
    for bona fide arbitrage purposes only and other than as disclosed in a
    Schedule 13G on file with the Commission prior to February 13, 1998, (ii)
    any such person, entity or group that prior to February 13,
 
                                       36
<PAGE>
    1998, had filed such a Schedule with the Commission has acquired or proposes
    to acquire, through the acquisition of stock, the formation of a group or
    otherwise, beneficial ownership of 1% or more of any class or series of
    capital stock of the Company (including the Shares), or shall have been
    granted any right, option or warrant, conditional or otherwise, to acquire
    beneficial ownership of 1% or more of any class or series of capital stock
    of the Company (including the Shares), (iii) any person or group shall have
    entered into a definitive agreement or an agreement in principle or made a
    proposal with respect to a tender offer or exchange offer or a merger,
    consolidation or other business combination with or involving the Company or
    (iv) any person shall have filed a Notification and Report Form under the
    HSR Act (or amended a prior filing to increase the applicable filing
    threshold set forth therein) or made a public announcement reflecting an
    intent to acquire the Company or any assets or subsidiaries of the Company;
 
        (g) any approval, permit, authorization, favorable review or consent of
    any Governmental Entity (including those described or referred to in Section
    15) shall not have been obtained on terms satisfactory to Purchaser in its
    sole discretion;
 
        (h) the Purchaser shall become aware (i) that any material contractual
    right of the Company or any of its subsidiaries shall be impaired or
    otherwise adversely affected as a result of the transactions contemplated by
    the Offer or the Proposed Merger, or (ii) of any covenant, term or condition
    in any of the Company's or any of its subsidiaries' instruments or
    agreements that are or may be materially adverse to the value of the Shares
    in the hands of the Purchaser, Computer Associates or any other affiliate of
    Computer Associates (including, without limitation, any event of default
    that may ensue as a result of the consummation of the Offer, the Proposed
    Merger or any other business combination or the acquisition of control of
    the Company); or
 
        (i) the Purchaser shall have reached an agreement or understanding with
    the Company providing for termination of the Offer, or the Purchaser,
    Computer Associates or any other affiliate of Computer Associates shall have
    entered into a definitive agreement or announced an agreement in principle
    with the Company providing for a merger or other business combination with
    the Company or the purchase of stock or assets of the Company;
 
which, in the sole judgment of the Purchaser in any such case, and regardless of
the circumstances (including any action or inaction by the Purchaser, Computer
Associates or any other affiliate of Computer Associates) giving rise to any
such condition, makes it inadvisable to proceed with the Offer and/or with such
acceptance for payment or payment.
 
    The foregoing conditions are for the sole benefit of the Purchaser and
Computer Associates and may be asserted by the Purchaser regardless of the
circumstances giving rise to any such condition or may be waived by the
Purchaser in whole or in part at any time and from time to time in its sole
discretion. The failure by the Purchaser at any time to exercise any of the
foregoing rights will not be deemed a waiver of any such right, the waiver of
any such right with respect to particular facts and circumstances will not be
deemed a waiver with respect to any other facts and circumstances and each such
right will be deemed an ongoing right that may be asserted at any time and from
time to time. Any determination by the Purchaser concerning the events described
in this Section 14 will be final and binding upon all parties.
 
    A public announcement may be made of a material change in, or waiver of,
such conditions and the Offer may, in certain circumstances, be extended in
connection with any such change or waiver.
 
    The Purchaser acknowledges that the Commission believes that (a) if the
Purchaser is delayed in accepting the Shares it must either extend the Offer or
terminate the Offer and promptly return the Shares and (b) the circumstances in
which a delay in payment is permitted are limited and do not include unsatisfied
conditions of the Offer, except with respect to any approval required under the
HSR Act and most other regulatory approvals.

    15. CERTAIN LEGAL MATTERS; REQUIRED REGULATORY APPROVALS.  Except as set
forth in this Offer to Purchase, based on its review of publicly available
filings by the Company with the Commission and other publicly available
information regarding the Company, the Purchaser is not aware of any licenses or
regulatory permits that appear to be material to the business of the Company and
its subsidiaries, taken as a whole, and that might be adversely affected by the
Purchaser's acquisition of Shares (and the indirect acquisition of the stock of
the Company's subsidiaries) as contemplated herein, or any filings, approvals or
other actions by or with any domestic, foreign or supranational governmental
authority or administrative or regulatory agency that would be required for the
acquisition or ownership of the Shares (or the indirect acquisition of the stock
of the Company's subsidiaries) by the Purchaser pursuant to the Offer as
contemplated herein. Should any such approval or other action be required, it is
presently contemplated that such approval or action would be sought except as
described below under "State Takeover Laws." Should any such approval or other
action be required, there can be no assurance that any such approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to the Company's or its subsidiaries' businesses,
or that certain parts of the Company's, Computer Associates' or any of their
respective subsidiaries' businesses might not have to be disposed of or held
separate or other substantial conditions complied with in order to obtain such
approval or action or in the event that such approvals were not obtained or such
actions were not taken. The Purchaser's obligation to purchase and pay for
Shares is subject to certain conditions, including conditions with respect to
litigation and governmental actions. See the Introduction and Section 14 for a
description thereof.
 
    STATE TAKEOVER LAWS.  The Company is incorporated under the laws of Nevada.
As described above, pursuant to Nevada Control Share Acquisition Statute an
"acquiring person", who acquires a "controlling interest" in an "issuing
corporation," may not exercise voting rights on any "control shares" unless such
voting rights are conferred by a majority vote of the disinterested stockholders
of the issuing corporation at a meeting of such stockholders. See
"Introduction."
 
    The above provisions do not apply if the articles of incorporation or bylaws
of the Company in effect on the tenth day following the acquisition of a
controlling interest by an acquiring person provide that said provisions do not
apply. The Articles and Bylaws currently do not exclude the Company from the
restrictions imposed by such provisions. The Control Share Condition would be
satisfied if the Bylaws were amended such that, on the tenth day following
consummation of the Offer, the Bylaws provide that the provisions of the Nevada
Control Share Acquisition Statute do not apply, or, if the Purchaser, in its
sole discretion, were satisfied that the Nevada Control Share Acquisition
Statute was invalid or its restrictions were otherwise inapplicable to the
Purchaser in connection with the Offer and the Proposed Merger for any reason,
including, without limitation, those specified in the Nevada Control Share
Acquisition Statute.
 
    As further described above, the Nevada Business Combination Statute
restricts the ability of a "resident domestic corporation" to engage in any
combination with an "interested stockholder" for three years following the
interested stockholder's date of acquiring the shares that caused such
stockholder to become an interested stockholder, unless the combination or the
purchase of shares by the interested stockholder on the interested stockholder's
date of acquiring the shares that caused such stockholder to become an
interested stockholder is approved by the board of directors of the resident
domestic corporation before that date. See "Introduction." If the combination
was not previously approved, the interested stockholder may effect a combination
after the three-year period only if such stockholder receives approval from a
majority of the disinterested shares or the offer meets certain fair price
criteria.
 
    The Business Combination Condition would be satisfied if the Board approved
the Offer and the Proposed Merger prior to consummation of the Offer and the
Proposed Merger or if the Purchaser, in its sole discretion, were satisfied that
the Nevada Business Combination Statute was invalid or its restrictions were
otherwise inapplicable to the Purchaser in connection with the Offer and the
Proposed Merger for any reason, including, without limitation, those specified
in the Nevada Business Combination Statute.
 
                                       38

    A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In 1982, in Edgar v. MITE Corp., the Supreme
Court of the United States invalidated on constitutional grounds the Illinois
Business Takeover Statute, which, as a matter of state securities law, made
takeovers of corporations meeting certain requirements more difficult. However,
in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court held that
the State of Indiana may, as a matter of corporate law, and, in particular, with
respect to those aspects of corporate law concerning corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of a
target corporation without the prior approval of the remaining stockholders. The
state law before the Supreme Court was by its terms applicable only to
corporations that had a substantial number of stockholders in the state and were
incorporated there.
 
    The Company, directly or through subsidiaries, conducts business in a number
of states throughout the United States, some of which have enacted takeover
laws. The Purchaser does not know whether any of these laws will, by their
terms, apply to the offer and has not complied with any such laws. Should any
person seek to apply any state takeover law, the Purchaser will take such action
as then appears desirable, which may include challenging the validity or
applicability of any such statute in appropriate court proceedings. In the event
it is asserted that one or more state takeover laws is applicable to the Offer
and the Proposed Merger and an appropriate court does not determine that it is
inapplicable or invalid as applied to the Offer, the Purchaser might be required
to file certain information with, or receive approvals from, the relevant state
authorities. In addition, if enjoined, the Purchaser might be unable to accept
for payment any shares tendered pursuant to the Offer or be delayed in
continuing or consummating the Offer or the Proposed Merger. In such case, the
Purchaser may not be obligated to accept for payment any Shares tendered. See
Section 14.
 
    ANTITRUST.  Under the HSR Act, and the rules and regulations that have been
promulgated thereunder by the Federal Trade Commission (the "FTC"), certain
acquisition transactions may not be consummated until certain information and
documentary material has been furnished for review by the Antitrust Division of
the Department of Justice (the "Antitrust Division") and the FTC and certain
waiting period requirements have been satisfied. The acquisition of Shares
pursuant to the Offer and the Proposed Merger is subject to such requirements.
 
    On February 13, 1998, Computer Associates filed a Premerger Notification and
Report Form with the Antitrust Division and the FTC under the HSR Act in
connection with the purchase of Shares that would include Shares acquired
pursuant to the Offer and the Proposed Merger, and the required waiting period
will expire at 11:59 p.m., New York City time, on March 16, 1998, unless earlier
terminated by the Antitrust Division or the FTC or the Purchaser receives a
request for additional information or documentary material prior thereto. If,
within such 30-calendar-day waiting period, either the FTC or the Antitrust
Division were to request additional information or documentary material from
Computer Associates, the waiting period would be extended for an additional
period of 20 calendar days following the date of substantial compliance with
such request by Computer Associates. Only one extension of the waiting period
pursuant to a request for additional information is authorized by the rules
promulgated under the HSR Act. Thereafter, the waiting period could be extended
only by court order or with the consent of Computer Associates. The additional
20-calendar-day waiting period may be terminated sooner by the FTC or the
Antitrust Division. Although the Company is required to file certain information
and documentary material with the Antitrust Division and the FTC in connection
with the Offer, neither the Company's failure to make such filings nor a request
made to the Company from the Antitrust Division or the FTC for additional
information or documentary material will extend the waiting period with respect
to the purchase of Shares pursuant to the Offer and the Proposed Merger.
 
    The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the acquisition of Shares by the
Purchaser pursuant to the Offer and the Proposed
 
                                       39
<PAGE>
Merger. At any time before or after the Purchaser's purchase of Shares, the
Antitrust Division or the FTC could take such action under the antitrust laws as
either deems necessary or desirable in the public interest, including seeking to
enjoin the purchase of Shares pursuant to the Offer and the Proposed Merger, the
divestiture of Shares purchased pursuant to the Offer or the divestiture of
substantial assets of Computer Associates, the Company or any of their
respective subsidiaries or affiliates. Private parties as well as state
attorneys general may also bring legal actions under the antitrust laws under
certain circumstances. See Section 14.
 
    Based upon an examination of publicly available information relating to the
businesses in which the Company is engaged, the Purchaser believes that the
acquisition of Shares pursuant to the Offer and the Proposed Merger should not
violate the applicable antitrust laws. Nevertheless, there can be no assurance
that a challenge to the Offer and the Proposed Merger on antitrust grounds will
not be made, or, if such challenge is made, what the result will be. See Section
14.
 
    EC MERGER REGULATION.  According to publicly available information, the
Company may conduct substantial operations within the European Community (the
"EC") and certain of the individual member states of the EC. The EC Merger
Regulation requires that notices of concentrations with a "community dimension"
be provided to the EC Commission for review and approval prior to being put into
effect. The Offer would be deemed to have a "community dimension" if the
combined aggregate worldwide annual revenues of both the Company and Computer
Associates exceed ECU 5 billion, if the community-wide annual revenues of each
of the Company and Computer Associates exceed ECU 250 million and if both the
Company and Computer Associates do not receive more than two-thirds of their
respective community-wide revenues from one and the same member state. Based
upon publicly available information, the Purchaser believes that the Offer would
be considered to have a "community dimension." If the Offer falls within the EC
Merger Regulation, the EC Commission, as opposed to individual member states,
has exclusive jurisdiction to review it, subject to certain exceptions.
 
    Under the EC Merger Regulation, a concentration that meets the foregoing
guidelines requires the filing of a notice in a prescribed form with the EC
Commission. This filing must normally be made within seven days of the earlier
of the announcement of a public bid, the conclusion of the relevant agreement or
the acquisition of a controlling interest, although extensions of time are
sometimes granted. Transactions subject to the filing requirements of the EC
Merger Regulation are suspended automatically until three weeks after receipt of
the notice. The EC Commission may extend the suspension period for such period
as it finds necessary to make a final decision on the legality of the
transaction. In the case of a public bid, the bidder may acquire shares of the
target company during the suspension period, but may not vote such shares until
after the end of the period unless the EC Commission grants permission to do so
in order to maintain the full value of the bidder's investment.
 
    The EC Commission must decide whether to initiate proceedings within one
month after the receipt of the notice, subject to certain extensions for EC
holidays or if an individual member state has requested a referral of the
transaction. If proceedings are initiated, the EC Commission must reach a
decision in the proceedings within four months of the commencement of the
proceedings. If the EC Commission fails to reach a decision within either of
these time periods the transaction will be deemed to be compatible with the
common market.
 
    If the EC Commission declares the Offer to be not compatible with the common
market, it may prevent the consummation of the transaction, order a divestiture
if the transaction has already been consummated or impose conditions or other
obligations. In the event that the transaction is found not to be subject to the
EC Merger Regulation, various national merger control regimes of the member
states may apply, resulting in the possibility that approvals may be necessary
from the various national authorities.
 
                                       40
<PAGE>
    There can be no assurance that a challenge to the Offer will not be made
pursuant to the EC Merger Regulation or, alternatively, pursuant to the merger
regulations of one or more of the various member states, or, if such a challenge
is made, what the outcome will be. See Section 14.
 
    INVESTMENT CANADA ACT.  According to publicly available information, the
Company conducts certain operations in Canada. The Investment Canada Act (the
"ICA") requires that notice of the acquisition of "control" (as defined in the
ICA) by "non-Canadians" (as defined by the ICA) of any "Canadian business" (as
defined by the ICA) be furnished to Investment Canada, a Canadian governmental
agency.
 
    The acquisition of Shares by the Purchaser pursuant to the Offer may
constitute an indirect acquisition of a "Canadian business" within the meaning
of the ICA. The Purchaser intends to file any required notice under the ICA.
 
    CANADIAN PRE-MERGER NOTIFICATION REQUIREMENTS.  Certain provisions of
Canada's Competition Act require pre-notification to the Director of
Investigation and Research appointed under the Competition Act (the "Canadian
Director") of significant corporate transactions, such as the acquisition of a
large percentage of the stock of a public company which has Canadian operations,
or a merger or consolidation involving such an entity. Pre-notification is
generally required with respect to transactions in which the parties to the
transactions and their affiliates have assets in Canada, or annual gross
revenues from sales in, from or into Canada, in excess of Cdn. $400 million and
which involve the direct or indirect acquisition of an operating business, the
value of the assets of which, or the gross revenues from sales in or from Canada
generated from these assets, exceed Cdn. $35 million per year. For transactions
subject to the notification requirements, notice must be given seven or 21 days
prior to the completion of the transaction depending on the information provided
to the Canadian Director. The Canadian Director may waive the waiting period.
After the applicable waiting period expires or is waived, the transaction may be
completed. If the Canadian Director determines that the proposed transaction
prevents or lessens, or is reasonably likely to prevent or lessen, competition
substantially in a definable market, the Canadian Director may apply to the
Competition Tribunal, a special purpose Canadian tribunal, to, among other
things, require the disposition of the Canadian assets acquired in such
transaction. The Purchaser intends to file any required notice and information
with respect to its proposed acquisition with the Canadian Director for an
advance ruling certificate to the effect that the Offer or Proposed Merger would
not prevent or lessen, or be likely to prevent or lessen, competition
substantially.
 
    OTHER FOREIGN APPROVALS.  According to publicly available information, the
Company also owns property and conducts business in a number of other foreign
countries and jurisdictions. In connection with the acquisition of the Shares
pursuant to the Offer or the Proposed Merger, the laws of certain of those
foreign countries and jurisdictions may require the filing of information with,
or the obtaining of the approval of, governmental authorities in such countries
and jurisdictions. The governments in such countries and jurisdictions might
attempt to impose additional conditions on the Company's operations conducted in
such countries and jurisdictions as a result of the acquisition of the Shares
pursuant to the Offer or the Proposed Merger. There can be no assurance that the
Purchaser will be able to cause the Company or its subsidiaries to satisfy or
comply with such laws or that compliance or noncompliance will not have adverse
consequences for the Company or any subsidiary after purchase of the Shares
pursuant to the Offer or the Proposed Merger Combination.
 
    MARGIN CREDIT REGULATIONS.  Federal Reserve Board Regulations G,T,U and X
(the "Margin Credit Regulations") restrict the extension or maintenance of
credit for the purpose of buying or carrying margin stock, including the Shares,
if the credit is secured directly or indirectly thereby. The borrowings under
the Credit Facilities will not be directly secured by a pledge of the Shares. In
addition, Computer Associates and the Purchaser believe that such borrowings
will not be "indirectly secured" within the meaning of the Margin Credit
Regulations, as interpreted. Accordingly, Computer Associates and the Purchaser
believe that the Margin Credit Regulations are not applicable to the borrowings
under the Credit Facilities.

    16. CERTAIN FEES AND EXPENSES.  Bear, Stearns & Co. Inc. ("Bear Stearns") is
acting as Dealer Manager in connection with the Offer and as financial advisor
to Computer Associates and the Purchaser in connection with the proposed
acquisition of the Company. Computer Associates is obligated to pay to Bear
Stearns, if, as more fully described in the engagement letter relating thereto,
during the term of the engagement or within 12 months thereafter Computer
Associates acquires the Company or more than 50% of its outstanding voting
securities, a fee of $5 million and a fee of $1 million (which will be credited
against such $5 million fee) if Computer Associates requests Bear Stearns to
render a customary fairness opinion. Bear Stearns is also entitled to act as
sole lead underwriter, placement agent and financial advisor in connection with
certain debt and equity financings (and certain refinancings) and certain asset
sales for a specified period following the acquisition and to receive fees in
connection therewith. In addition, Computer Associates has agreed to reimburse
Bear Stearns for its reasonable expenses, including reasonable fees and
disbursements of its counsel, incurred in rendering its services under its
engagement agreement with Computer Associates and has agreed to indemnify Bear
Stearns against certain liabilities and expenses in connection with the Offer
and the Proposed Merger, including certain liabilities under the federal
securities laws. Bear Stearns from time to time renders various investment
banking services to Computer Associates and its affiliates for which it is paid
customary fees.
 
    In the ordinary course of business, Bear Stearns and its affiliates may
actively trade the securities of the Company for their own account and for the
account of customers and accordingly may, at any time, hold long or short
positions in such securities. As of February 16, 1998, Bear Stearns held for its
own account and the account of its affiliates a net short position of
approximately 700 shares.
 
    MacKenzie Partners, Inc. has been retained by Computer Associates as
Information Agent in connection with the Offer. The Information Agent may
contact holders of Shares and Rights by mail, telephone, telex, telegraph and
personal interview and may request brokers, dealers and other nominee
stockholders to forward material relating to the Offer to beneficial owners of
Shares and Rights. Computer Associates will pay the Information Agent reasonable
and customary compensation for all such services in addition to reimbursing the
Information Agent for reasonable out-of-pocket expenses in connection therewith.
Computer Associates has agreed to indemnify the Information Agent against
certain liabilities and expenses in connection with the Offer, including certain
liabilities under the federal securities laws.
 
    In addition, First Chicago Trust Company of New York has been retained as
the Depositary. Computer Associates will pay the Depositary reasonable and
customary compensation for its services in connection with the Offer, will
reimburse the Depositary for its reasonable out-of-pocket expenses in connection
therewith and will indemnify the Depositary against certain liabilities and
expenses in connection therewith, including certain liabilities under the

    Except as set forth above, neither Computer Associates nor the Purchaser
will pay any fees or commissions to any broker, dealer or other person (other
than the Information Agent and the Dealer Manager) for soliciting tenders of
Shares and Rights pursuant to the Offer. Brokers, dealers, commercial banks and
trust companies and other nominees will, upon request, be reimbursed by the
Purchaser for customary clerical and mailing expenses incurred by them in
forwarding offering materials to their customers.
 
    17. MISCELLANEOUS.  The Offer is not being made to (nor will tenders be
accepted from or on behalf of) holders of Shares or Rights residing in any
jurisdiction in which the making of the Offer or the acceptance thereof would
not be in compliance with the securities, blue sky or other laws of such
jurisdiction. However, the Purchaser may, in its discretion, take such action as
it may deem necessary to make the Offer in any jurisdiction and extend the Offer
to holders of Shares in such jurisdiction.
 
    In any jurisdiction where the securities, blue sky or other laws require the
Offer to be made by a licensed broker or dealer, the Offer will be deemed to be
made on behalf of the Purchaser by the Dealer Manager or one or more registered
brokers or dealers that are licensed under the laws of such jurisdiction.

    This Letter of Transmittal is to be completed by stockholders of Computer
Sciences Corporation if certificates evidencing Shares and/or Rights (each as
defined in the Offer to Purchase, dated February 17, 1998, (the "Offer to
Purchase")), are to be forwarded herewith or, unless an Agent's Message (as
defined in the Offer to Purchase) is utilized, if tenders of Shares and/or
Rights are to be made by book-entry transfer to an account maintained by First
Chicago Trust Company of New York (the "Depositary") at The Depository Trust
Company ("DTC") or Philadelphia Depository Trust Company ("PDTC") (each a
"Book-Entry Transfer Facility" and collectively referred to as the "Book-Entry
Transfer Facilities"), pursuant to the procedures set forth in Section 3 of the
Offer to Purchase. Stockholders who tender Shares or Rights by book-entry
transfer are referred to herein as "Book-Entry Stockholders." UNLESS AND UNTIL
COMPUTER ASSOCIATES INTERNATIONAL, INC., A DELAWARE CORPORATION (THE
"PURCHASER"), DECLARES THAT THE RIGHTS CONDITION (AS DEFINED IN THE OFFER TO
PURCHASE) IS SATISFIED, HOLDERS OF SHARES WILL BE REQUIRED TO TENDER ONE RIGHT
FOR EACH SHARE TENDERED IN ORDER TO EFFECT A VALID TENDER OF SUCH SHARE. If the
Distribution Date (as defined in the Offer to Purchase) does not occur prior to
the Expiration Date (as defined in the Offer to Purchase), a tender of Shares
will also constitute a tender of the associated Rights. If the Distribution Date
has occurred and the certificates evidencing Rights ("Rights Certificates") are
distributed by Computer Sciences Corporation, a Nevada corporation, to holders
of Shares prior to the time a holder's Shares are tendered pursuant to the Offer
(as defined in the Offer to Purchase), in order for Rights (and the
corresponding Shares) to be validly tendered, Rights Certificates representing a
number of Rights equal to the number of Shares tendered must be delivered to the
Depositary or, if available, a Book-Entry Confirmation (as defined in the Offer
to Purchase) received by the Depositary with respect thereto. If the
Distribution Date has occurred and Rights Certificates are not distributed prior
to the time Shares are tendered pursuant to the Offer, Rights may be tendered
prior to a stockholder receiving Rights Certificates by use of the guaranteed
delivery procedure described below. In any case, a tender of Shares constitutes
an agreement by the tendering stockholder to deliver Rights Certificates
representing a number of Rights equal to the number of Shares tendered pursuant
to the Offer to the Depositary within three business days after the date Rights
Certificates are distributed. The Purchaser reserves the right to require that
the Depositary receive Rights Certificates, or a Book-Entry Confirmation, if
available, with respect to such Rights, prior to accepting the related Shares
for payment pursuant to the Offer if the Distribution Date has occurred prior to
the Expiration Date. See Section 3 of the Offer to Purchase. The Purchaser will
not pay any additional consideration for any Rights tendered pursuant to the
Offer.
 
    Holders of Shares and Rights whose certificates for such Shares (the "Share
Certificates") and, if applicable, Rights Certificates, are not immediately
available (including, if the Distribution Date has occurred, but Rights
Certificates have not yet been distributed) or who cannot deliver their Share
Certificates or, if applicable, their Rights Certificates, and all other
required documents to the Depositary on or prior to the Expiration Date or who
cannot complete the procedures for book-entry transfer on a timely basis, must
tender their Shares and Rights according to the guaranteed delivery procedures
set forth in Section 3 of the Offer to Purchase.

"Rights") issued pursuant to the Rights Agreement dated as of December 21, 1988,
as amended and restated as of August 1, 1996 (the "Rights Agreement"), between
the Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent, at a
purchase price of $108 per Share (and associated Right), net to the seller in
cash, without interest thereon, in each case upon the terms and subject to the
conditions set forth in the Offer to Purchase, dated February 17, 1998 (the
"Offer to Purchase"), receipt of which is hereby acknowledged, and in this
Letter of Transmittal (which, together with the Offer to Purchase and any
amendments or supplements hereto or thereto, collectively constitute the
"Offer"). Unless the context otherwise requires, all references to Shares shall
include the associated Rights and all references to the Rights shall include all
benefits that may inure to holders of the Rights pursuant to the Rights
Agreement. The undersigned understands that the Purchaser reserves the right to
transfer or assign, in whole or from time to time in part, to one or more of its
subsidiaries or affiliates the right to purchase all or any portion of the
Shares and Rights tendered pursuant to the Offer.
 
    On February 2, 1998, the Company publicly announced a two-for-one split of
the Shares in the form of a 100% stock dividend thereon (the "Stock Split
Dividend"). The Company further announced that the Stock Split Dividend will be
payable on March 23, 1998 to holders of record of Shares on March 2, 1998. The
effect of the Stock Split Dividend on the terms of the Offer is described in
more detail in the Offer to Purchase.
 
    Subject to, and effective upon, acceptance for payment of and payment for
the Shares and Rights tendered herewith in accordance with the terms and subject
to the conditions of the Offer, the undersigned hereby sells, assigns, and
transfers to, or upon the order of, the Purchaser all right, title and interest
in and to all of the Shares and Rights that are being tendered hereby and any
and all dividends on the Shares or any distribution (including, without
limitation, the issuance of additional Shares pursuant to the Stock Split
Dividend or any other stock dividend or stock split, the issuance of other
securities or the issuance of rights for the purchase of any securities) with
respect to the Shares or Rights (other than the Redemption Price (as defined in
the Offer to Purchase)) that is declared or paid by the Company on or after
February 13, 1998 and is payable or distributable to stockholders of record on a
record date prior to the transfer into the name of the Purchaser or its nominees
or transferees on the Company's stock transfer records of the Shares and Rights
purchased pursuant to the Offer (except that if the Rights are redeemed by the
Company's Board of Directors, tendering stockholders who are holders of record
as of the applicable record date will be entitled to receive and retain the
Redemption Price) (a "Distribution"), and constitutes and irrevocably appoints
the Depositary the true and lawful agent, attorney-in-fact and proxy of the
undersigned to the full extent of the undersigned's rights with respect to such
Shares and Rights (and any Distributions) with full power of substitution (such
power of attorney and proxy being deemed to be an irrevocable power coupled with
an interest), to (a) deliver Share Certificates and Rights Certificates (as
defined in the Offer to Purchase) (and any Distributions), or transfer ownership
of such Shares or Rights on the account books maintained by the Book-Entry
Transfer Facilities together in either such case with all accompanying evidences
of transfer and authenticity, to or upon the order of the Purchaser upon receipt
by the Depositary, as the undersigned's agent, of the purchase price, (b)
present such Shares and Rights (and any Distributions) for transfer on the books
of the Company and (c) receive all benefits and otherwise exercise all rights of
beneficial ownership of such Shares and Rights (and any Distribution), all in
accordance with the terms and subject to the conditions of the Offer.

    The undersigned understands that if the Distribution Date (as defined in the
Offer to Purchase) has occurred and Rights Certificates have been distributed by
the Company to holders of the Shares prior to the time the Shares are tendered
herewith, in order for the Rights (and the corresponding Shares) to be validly
tendered, Rights Certificates representing a number of Rights equal to the
number of Shares being tendered herewith must be delivered to the Depositary or,
if available, a Book-Entry Confirmation (as defined in Instruction 2) must be
received by the Depositary with respect thereto. If the Distribution Date has
occurred and Rights Certificates have not been distributed prior to the time the
Shares are tendered herewith, the undersigned agrees to deliver the Rights
Certificates representing a number of Rights equal to the number of Shares
tendered herewith to the Depositary within three business days after the date
such Rights Certificates are distributed. The undersigned understands that if
the Rights Condition is not satisfied, the Purchaser reserves the right to
require that the Depositary receive Rights Certificates, or a Book-Entry
Confirmation, if available, with respect to such Rights prior to accepting the
related Shares for payment, if the Distribution Date has occurred prior to the
Expiration Date. In that event, payment for the Shares tendered and accepted for
payment pursuant to the Offer will be made only after timely receipt by the
Depositary of, among other things, such Rights Certificates.
 
    The undersigned hereby irrevocably appoints Sanjay Kumar and Steven M.
Woghin, and each of them, the attorneys-in-fact and proxies of the undersigned,
each with full power of substitution, to vote in such manner as each such
attorney and proxy or his substitute shall, in his sole discretion, deem proper,
and otherwise act (including pursuant to written consent) with respect to all of
the Shares and Rights tendered hereby which have been accepted for payment by
the Purchaser prior to the time of such vote or action (and any Distributions)
which the undersigned is entitled to vote at any meeting of stockholders
(whether annual or special and whether or not an adjourned meeting) of the
Company, or by written consent in lieu of such meeting, or otherwise. This power
of attorney and proxy is coupled with an interest in the Company and in the
Shares and Rights and is irrevocable and is granted in consideration of, and is
effective upon, the acceptance for payment of such Shares and Rights by the
Purchaser in accordance with the terms of the Offer. Such acceptance for payment
shall revoke, without further action, any other power of attorney or proxy
granted by the undersigned at any time with respect to such Shares and Rights
(and any Distributions) and no subsequent powers of attorney or proxies will be
given (and if given will be deemed not to be effective) with respect thereto by
the undersigned. The undersigned understands that the Purchaser reserves the
right to require that, in order for the Shares and the Rights to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares and Rights, the Purchaser or its designees is able to exercise full
voting rights with respect to such Shares, Rights and other securities,
including voting at any meeting of stockholders.
 
    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares and the
Rights tendered hereby (and any Distributions) and that, when the same are
accepted for payment by the Purchaser, the Purchaser will acquire good,
marketable and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and the same will not be subject to any
adverse claim. The undersigned, upon request, will execute and deliver any
additional documents deemed by the Depositary or the Purchaser to be necessary
or desirable to complete the sale, assignment and transfer of the Shares and
Rights tendered hereby (and any Distributions). In addition, the undersigned
shall promptly remit and transfer to the Depositary for the account of the
Purchaser any and all other Distributions in respect of the Shares and the
Rights tendered hereby, accompanied by appropriate documentation of transfer
and, pending such remittance or appropriate assurance thereof, the Purchaser
shall be entitled to all rights and privileges as owner of any such
Distributions, and may withhold the entire purchase price or deduct from the
purchase price of Shares and Rights tendered hereby the amount or value thereof,
as determined by the Purchaser in its sole discretion.
 
    All authority herein conferred or herein agreed to be conferred shall not be
affected by, and shall survive, the death or incapacity of the undersigned and
any obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, legal representatives, successors and assigns of the
undersigned. Except as stated in the Offer to Purchase, this tender is
irrevocable, provided that the Shares and Rights tendered pursuant to the Offer
may be withdrawn at any time prior to the Expiration Date and, unless
theretofore accepted for payment as provided in the Offer to Purchase, may also
be withdrawn at any time after April 17, 1998 (or such later date as may apply
in case the Offer is extended).
 
    The undersigned understands that tenders of Shares and Rights pursuant to
any one of the procedures described in Section 3 of the Offer to Purchase and in
the instructions hereto will constitute a binding agreement between the
undersigned and the Purchaser upon the terms and subject to the conditions of
the Offer.

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
    1.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required (i) if this Letter of Transmittal is signed by the
registered holder (which term, for purposes of this document, shall include any

tendered herewith, unless such holder has completed either the box entitled

    2.  DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES.  This Letter of
Transmittal is to be used either if Share Certificates or Rights Certificates

such Shares into the Depositary's account at a Book-Entry Transfer Facility, as
well as this Letter of Transmittal (or a facsimile hereof), properly completed

(as defined in the Offer to Purchase) in the case of a book-entry delivery, and
any other documents required by this Letter of Transmittal, must be received by

documents required by this Letter of Transmittal), must be received by the
Depositary at one of its addresses set forth herein prior to the Expiration Date
or, if later, within three business days after the date such Rights Certificates

but Rights Certificates have not yet been distributed by the Company) or who

required documents to the Depositary prior to the Expiration Date or who cannot
complete the procedures for delivery by book-entry transfer on a timely basis
may tender their Shares and Rights by properly completing and duly executing a
Notice of Guaranteed Delivery pursuant to the guaranteed delivery procedures set

Certificates are forwarded separately to the Depositary, a properly completed
and duly executed Letter of Transmittal (or facsimile hereof) must accompany
each such delivery.
 
    THE METHOD OF DELIVERY OF SHARE CERTIFICATES, RIGHTS CERTIFICATES (IF
APPLICABLE), THIS LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS,
INCLUDING DELIVERY THROUGH A BOOK-ENTRY TRANSFER FACILITY, IS AT THE OPTION AND
SOLE RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE DEEMED MADE
ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.

    No alternative, conditional or contingent tenders will be accepted and no

<PAGE>
    3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares and Rights and any other
required information should be listed on a separate schedule attached hereto and
separately signed on each page thereof in the same manner as this Letter of
Transmittal is signed.
 
    4.  PARTIAL TENDERS (NOT APPLICABLE TO BOOK-ENTRY STOCKHOLDERS).  If fewer
than all the Shares or Rights evidenced by any certificate submitted are to be
tendered, fill in the number of Shares or Rights which are to be tendered in the
box entitled "Number of Shares Tendered" or "Number of Rights Tendered" as
appropriate. In such case, new certificate(s) for the remainder of the Shares or
Rights that were evidenced by your old certificate(s) will be sent to you,
unless otherwise provided in the appropriate box marked "Special Payment
Instructions" and/or "Special Delivery Instructions" on this Letter of
Transmittal, as soon as practicable after the Expiration Date. All Shares and
Rights represented by certificates delivered to the Depositary will be deemed to
have been tendered unless otherwise indicated.
 
    5.  SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
and Rights tendered hereby, the signature(s) must correspond exactly with the
name(s) as written on the face of the certificate(s) without alteration,
enlargement or any change whatsoever.
 
    If any of the Shares or Rights tendered hereby are owned of record by two or
more joint owners, all such owners must sign this Letter of Transmittal.
 
    If any tendered Shares or Rights are registered in different names on
several certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.
 
    If this Letter of Transmittal or any certificates or stock powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and proper evidence satisfactory to the
Purchaser of their authority so to act must be submitted.
 
                                       12
<PAGE>
    When this Letter of Transmittal is signed by the registered owner(s) of the
Shares or Rights listed and transmitted hereby, no endorsements of certificates
or separate stock powers are required unless payment is to be made to or
certificates for Shares or Rights not tendered or purchased are to be issued in
the name of a person other than the registered owner(s). Signatures on such
certificates or stock powers must be guaranteed by an Eligible Institution.
 
    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Shares or Rights listed, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner(s) appear(s) on the
certificates. Signatures on such certificates or stock powers must be guaranteed
by an Eligible Institution.
 
    6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of purchased Shares and Rights to it or its order pursuant
to the Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Shares and Rights not tendered or purchased are to be
registered in the name of, any person other than the registered holder, or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder or such person) payable on
account of the transfer to such person will be deducted from the purchase price
unless satisfactory evidence of the payment of such taxes or exemption therefrom
is submitted.
 
    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.
 
    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check is to be issued
in the name of and/or certificates for unpurchased Shares or Rights are to be
returned to a person other than the signer of this Letter of Transmittal or if a
check is to be sent and/or such certificates are to be returned to someone other
than the signer of this Letter of Transmittal or to an address other than that
shown on the front cover hereof, the appropriate boxes on this Letter of
Transmittal should be completed. Stockholders tendering Shares or Rights by
book-entry transfer may request that Shares or Rights not purchased be credited
to such account maintained at such Book-Entry Transfer Facility as such
stockholder may designate hereon. If no such instructions are given, such Shares
or Rights not purchased will be returned by crediting the account at the
Book-Entry Transfer Facility designated above. See Instruction 1.
 
    8.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
may be directed to the Information Agent at its addresses set forth below.
Requests for additional copies of the Offer to Purchase and this Letter of
Transmittal may be directed to the Information Agent or to brokers, dealers,
commercial banks or trust companies.
 
    9.  31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal income
tax law, a stockholder whose tendered Shares or Rights are accepted for payment
is required to provide the Depositary with such stockholder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Depositary is
not provided with the correct TIN, the Internal Revenue Service may subject the
stockholder or other payee to a $50 penalty. In addition, payments that are made
to such stockholder or other payee with respect to Shares or Rights purchased
pursuant to the Offer may be subject to 31% backup withholding.
 
    Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the stockholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any such payments made to the stockholder or other payee. Backup withholding is
not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.
 
    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Depositary.
 
                                       13
<PAGE>
    The stockholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Shares or Rights or of the last transferee appearing on the transfers attached
to, or endorsed on, the Shares or Rights. If the Shares or Rights are in more
than one name or are not in the name of the actual owner, consult the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for additional guidance on which number to report.
 
    10.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Shares or Rights has been lost, destroyed or stolen, the
stockholder should promptly notify the Depositary. The stockholder will then be
instructed as to the steps that must be taken in order to replace the
certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates have
been followed.
 
    11.  WAIVER OF CONDITIONS.  The Conditions to the Offer may be waived, in
whole or in part, by the Purchaser in its sole discretion, at any time and from
time to time, in the case of any Shares or Rights tendered.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY HEREOF) OR AN
AGENT'S MESSAGE TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY ON
OR PRIOR TO THE EXPIRATION DATE.

  THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
         TIME, ON MONDAY, MARCH 16, 1998, UNLESS THE OFFER IS EXTENDED
 
                                                               February 17, 1998
 
To Brokers, Dealers, Commercial Banks,
Trust Companies and Other Nominees:
 
    We have been appointed by CAI Computer Services Corp., a Delaware
corporation (the "Purchaser") and a wholly owned subsidiary of Computer
Associates International, Inc., a Delaware corporation, to act as financial
advisor and Dealer Manager in connection with the Purchaser's offer to purchase
all of the shares of Common Stock, par value $1.00 per share (the "Shares"), of
Computer Sciences Corporation, a Nevada corporation (the "Company"), and (unless
and until the Purchaser declares that the Rights Condition (as defined below)
has been satisfied) the associated Series A Junior Participating Preferred Stock
Purchase Rights (the "Rights") issued pursuant to the Rights Agreement dated as
of December 21, 1988, as amended and restated as of August 1, 1996 (the "Rights
Agreement"), between the Company and ChaseMellon Shareholder Services, L.L.C.,
as Rights Agent, at a purchase price of $108 per Share (and associated Right),
net to the seller in cash, without interest thereon, in each case upon the terms
and subject to the conditions set forth in the Offer to Purchase, dated February
17, 1998 (the "Offer to Purchase"), and in the related Letter of Transmittal
(which, together with any amendments or supplements thereto, collectively
constitute the "Offer") enclosed herewith. Unless and until the Purchaser
declares that the Rights Condition is satisfied, holders of Shares will be
required to tender one associated Right for each Share tendered in order to
effect a valid tender of such Share. If the Distribution Date (as defined in the
Offer to Purchase) does not occur prior to the Expiration Date (as defined in
the Offer to Purchase), a tender of Shares will also constitute a tender of the
associated Rights. If the Distribution Date has occurred and Rights Certificates
(as defined in the Offer to Purchase) are distributed by the Company to holders
of Shares prior to the time a holder's Shares are tendered pursuant to the
Offer, in order for Rights (and the corresponding Shares) to be validly
tendered, Rights Certificates representing a number of Rights equal to the
number of Shares tendered must be delivered to the Depositary (as defined below)
or, if available, a Book-Entry Confirmation (as defined in the Offer to
Purchase) received by the Depositary with respect thereto. If the Distribution
Date has occurred and Rights Certificates are not distributed prior
<PAGE>
to the time Shares are tendered pursuant to the Offer, Rights may be tendered
prior to a stockholder receiving Rights Certificates by use of the guaranteed
delivery procedure described in Section 3 of the Offer to Purchase. In any case,
a tender of Shares constitutes an agreement by the tendering stockholder to
deliver Rights Certificates representing a number of Rights equal to the number
of Shares tendered pursuant to the Offer to the Depositary within three business
days after the date Rights Certificates are distributed. The Purchaser reserves
the right to require that the Depositary receive Rights Certificates, or a
Book-Entry Confirmation, if available, with respect to such Rights, prior to
accepting the related Shares for payment pursuant to the Offer if the
Distribution Date occurs prior to the Expiration Date. Holders of Shares and
Rights whose certificates for such Shares (the "Share Certificates") and, if
applicable, Rights Certificates, are not immediately available (including, if
the Distribution Date has occurred, but Rights Certificates have not yet been
distributed by the Company), or who cannot deliver their Share Certificates or,
if applicable, their Rights Certificates, and all other required documents to
the Depositary on or prior to the Expiration Date, or who cannot complete the
procedures for book-entry transfer on a timely basis, must tender their Shares
and Rights according to the guaranteed delivery procedures set forth in Section
3 of the Offer to Purchase. Unless the context otherwise requires, all
references to Shares shall include the associated Rights and all references to
the Rights shall include all benefits that may inure to holders of the Rights
pursuant to the Rights Agreement.
 
    On February 2, 1998, the Company publicly announced a two-for-one split of
the Shares in the form of a 100% stock dividend thereon (the "Stock Split
Dividend"). The Company further announced that the Stock Split Dividend will be
payable on March 23, 1998 to holders of record of Shares on March 2, 1998. The
effect of the Stock Split Dividend on the terms of the Offer is described in
more detail in the Offer to Purchase.
 
    Please furnish copies of the enclosed materials to those of your clients for
whose accounts you hold Shares or, if applicable, Rights registered in your name
or in the name of your nominee.
 
    The Offer is conditioned upon, among other things, (1) there being validly
tendered and not withdrawn prior to the expiration of the Offer a number of
Shares which, when added to the number of Shares beneficially owned by the
Purchaser and its affiliates, constitutes a majority of the total number of
outstanding Shares on a fully diluted basis on the date of purchase (assuming
the exercise or conversion, as applicable, of all outstanding options, rights
and convertible securities (if any) and the issuance of all Shares that the
Company is obligated to issue), (2) the Rights having been redeemed by the Board
of Directors of the Company or the Purchaser being satisfied, in its sole
discretion, that the Rights have been invalidated or are inapplicable to the
Offer and the Proposed Merger (the "Rights Condition"), (3) the Purchaser being
satisfied, in its sole discretion, that Sections 78.378 to 78.3793 of the Nevada
General Corporation Law are inapplicable to the Offer and the Proposed Merger
and (4) the Purchaser being satisfied, in its sole discretion, that Sections
78.411 to 78.444 of the Nevada General Corporation Law are inapplicable to the
Purchaser in connection with the Offer and the Proposed Merger. The Offer is
also subject to other terms and conditions contained in the Offer to Purchase.

until the Purchaser declares that the Rights Condition (as defined below) has
been satisfied) the associated Series A Junior Participating Preferred Stock
Purchase Rights (the "Rights") issued pursuant to the Rights Agreement dated as
of December 21, 1988, amended and restated as of August 1, 1996 (the "Rights

net to the seller in cash, without interest thereon, in each case upon the terms
and subject to the conditions set forth in the Offer to Purchase and in the
related Letter of Transmittal enclosed herewith. Unless and until the Purchaser

required to tender one associated Right for each Share tendered in order to
effect a valid tender of such Share. If the Distribution Date (as defined in the

of Shares constitutes an agreement by the tendering stockholder to deliver
Rights Certificates representing a number of Rights equal to the number of
Shares tendered pursuant to the Offer to the Depositary within three business
days after the date Rights Certificates are distributed. The Purchaser reserves

their Rights Certificates, and all other required documents to the Depositary on
or prior to the Expiration Date, or who cannot complete the procedures for
book-entry transfer on a timely basis, must tender their Shares and Rights
according to the guaranteed delivery procedures set forth in Section 3 of the

    net to you in cash without interest thereon, upon the terms and subject to

    split of the Shares in the form of a 100% stock dividend thereon (the "Stock
    Split Dividend"). The Company further announced that the Stock Split
    Dividend will be payable on March 23, 1998 to holders of record of Shares on
    March 2, 1998. The effect of the Stock Split Dividend on the terms of the
    Offer is described in more detail in the Offer to Purchase.
 
        3.  The Offer is being made for all outstanding Shares.
 
        4.  The Offer is conditioned upon, among other things, (1) there being
    validly tendered and not withdrawn prior to the Expiration Date a number of
    Shares which, when added to the number of Shares beneficially owned by the
    Purchaser and its affiliates, constitutes a majority of the total number of
    outstanding Shares on a fully diluted basis on the date of purchase
    (assuming the exercise or conversion, as applicable, of all outstanding
    options, rights and convertible securities (if any) and the issuance of all
    Shares that the Company is obligated to issue), (2) the Rights having been
    redeemed by the Board of Directors of the Company or the Purchaser being
    satisfied, in its sole discretion, that the Rights have been invalidated or
    are inapplicable to the Offer and the Proposed Merger (as defined in the
    Offer to Purchase) (the "Rights Condition"), (3) the Purchaser being
    satisfied, in its sole discretion, that Sections 78.378 to 78.3793 of the
    Nevada General Corporation Law are inapplicable to the Offer and the
    Proposed Merger and (4) the Purchaser being satisfied, in its sole
    discretion, that Sections 78.411 to 78.444 of the Nevada General Corporation
    Law are inapplicable to the Purchaser in connection with the Offer and the
    Proposed Merger. The Offer is also subject to other terms and conditions
    contained in the Offer to Purchase. See the Introduction and Sections 1, 14
    and 15 of the Offer to Purchase.
 
        5.  Tendering stockholders will not be obligated to pay brokerage fees
    or commissions or, except as otherwise provided in Instruction 6 of the
    Letter of Transmittal, stock transfer taxes on the purchase of Shares or
    Rights by the Purchaser pursuant to the Offer.
 
        6.  The Offer and withdrawal rights will expire at 12:00 midnight, New
    York City time, on Monday, March 16, 1998, unless the Offer is extended.

    Rights Certificates or, in the case of Shares, timely
<PAGE>
    confirmation of the book-entry transfer of such Shares and, if available,

    Section 3 of the Offer to Purchase, (b) the Letter of Transmittal (or a
    facsimile thereof), properly completed and duly executed, with any required
    signature guarantees or an Agent's Message (as defined in the Offer to
    Purchase), in connection with a book-entry delivery, and (c) any other
    documents required by the appropriate Letter of Transmittal. Accordingly,
    payment may not be made to all tendering stockholders at the same time
    depending upon when certificates for or, in the case of Shares,
    confirmations of book-entry transfer of such Shares (or associated Rights,
    if available) into the Depositary's account at a Book-Entry Transfer
    Facility are actually received by the Depositary.

for the Offer, or one or more registered brokers or dealers that are licensed
under the laws of such jurisdiction.
 
               INSTRUCTIONS WITH RESPECT TO THE OFFER TO PURCHASE
                      FOR CASH ALL SHARES OF COMMON STOCK
           (INCLUDING THE ASSOCIATED PREFERRED STOCK PURCHASE RIGHTS)
 
                                       OF
 
                         COMPUTER SCIENCES CORPORATION
 
    The undersigned acknowledge(s) receipt of your letter and the enclosed Offer
to Purchase, dated February 17, 1998 (the "Offer to Purchase"), and the related
Letter of Transmittal (which, together with any amendments thereto, collectively
constitute the "Offer") in connection with the offer by CAI Computer Services
Corp., a Delaware corporation (the "Purchaser") and a wholly owned subsidiary of
Computer Associates International, Inc., a Delaware corporation, to purchase all
of the shares of Common Stock, par value $1.00 per share (the "Shares"), of
Computer Sciences Corporation, a Nevada corporation (the "Company"), and (unless
and until the Purchaser declares that the Rights Condition (as defined in the
Offer to Purchase) has been satisfied) the associated Series A Junior
Participating Preferred Stock Purchase Rights (the "Rights") issued pursuant to
the Rights Agreement dated as of December 21, 1988, as amended and restated as
of August 1, 1996 (the "Rights Agreement"), between the Company and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent, at a purchase price of $108 per
Share (and associated Right), net to the seller in cash, without interest
thereon, in each case upon the terms and subject to the conditions set forth in
the Offer to Purchase.
 
    This will instruct you to tender to the Purchaser the number of Shares and
the number of Rights indicated below (or if no number is indicated below, all
Shares and Rights) which are held by you for the account of the undersigned,

<TABLE>

</TABLE>
 
<PAGE>
    Unless and until the Purchaser declares that the Rights Condition is
satisfied, holders of Shares are required to tender one associated Right for
each Share tendered in order to effect a valid tender of such Share. If
certificates representing Rights ("Rights Certificates") have been distributed
by the Company to holders of Shares, such holders will be required to validly
tender Rights Certificates representing a number of Rights equal to the number
of Shares being tendered in order to effect a valid tender of such Shares. If
Rights Certificates have not been distributed by the Company to holders of
Shares, a tender of Shares will also constitute a tender of the associated
Rights and only the line with respect to "Number of Shares to Be Tendered"
should be filled in. See Section 3 of the Offer to Purchase. Unless otherwise
indicated, it will be assumed that you instruct us to tender all Shares and
Rights held by us for your account and that you instruct us to tender all Rights
associated with Shares you have instructed us to tender.
 
    On February 2, 1998, the Company publicly announced a two-for-one split of
the Shares in the form of a 100% stock dividend thereon (the "Stock Split
Dividend"). The Company further announced that the Stock Split Dividend will be
payable on March 23, 1998 to holders of record of Shares on March 2, 1998. The
effect of the Stock Split Dividend on the terms of the Offer is described in
more detail in the Offer to Purchase.

ISLANDIA, N.Y., February 11, 1998 - Computer Associates International, Inc.

employees would bring to CA are critical to the combined company, and we plan 
to retain all of CSC's valuable employees.  The combined company's client 
base would be able to draw upon an unparalleled range of product offerings 
and services capabilities that are not now available in the marketplace from 
a platform-independent solutions provider."

Dear Van:

We have been disappointed by the response to date to the offer that we made 
last Tuesday to combine our two companies' businesses by means of a cash 
merger at $108 per CSC share.  As we have expressed from the beginning, our 
hope and intent was to prompt a meaningful effort to move ahead on both our 
parts to a negotiated transaction.

We believe that the best way, by far, to effect a combination of our two 
companies' businesses is through prompt negotiation of the terms followed by 
equally prompt implementation.  Every one of CSC's constituencies - 
shareholders, employees, customers and partners - will greatly benefit from 
this approach.  

We made it clear in our February 10th letter that we believed that we could 
bridge some of our differences with respect to value in a friendly 
transaction. The value of a friendly, promptly negotiated and concluded 
transaction is substantial in our view.  Our financial


<PAGE>

advisor, Michael Urfirer of Bear Stearns, has communicated to your financial 
advisor, Gene Sykes of Goldman Sachs, in very specific terms the magnitude of 
the value increase to your shareholders in a negotiated transaction.

Conversely, an adverse impact to CSC's business and people, substantially 
increased difficulty in combining the businesses and significant costs to 
both companies are inevitable outcomes of a contested process, which would 
result in a reduced value of CSC.  In short, we are proposing a transaction 
that has compelling value to your shareholders and other constituencies, 
especially when measured against a contested alternative.

Our request is simple.  We would like to commence negotiations with you this 
weekend.  We would be guided in those negotiations by the thinking reflected 
in my letters of February 6 and 10, which remains unchanged, except as to 
price.  I very much look forward to this.  We are committed to the business 
strategy of combining our two companies' businesses and, as I have stated, 
believe a negotiated transaction is clearly preferable for all concerned.  
However, as we communicated to Mr. Sykes earlier today, if substantive 
negotiations have not started by Monday at 12:00 noon EST, we will have no 
choice but to move ahead on a unilateral basis at a substantially lower price 
than we communicated to Mr. Sykes which would be required to reflect the 
diminution in value as indicated above.

We hope this demonstrates our continuing efforts to consummate a friendly 
transaction.  It is truly important to us that you and your Board are fully 
informed at this critical stage.

I look forward to hearing from you.  I can be reached at the numbers I 
previously left with you or through Michael Urfirer of Bear Stearns.

                              Sincerely,

                              Sanjay Kumar

ISLANDIA, N.Y., February 17, 1998 -- Computer Associates International, Inc. 
(NYSE: CA) today announced that it has commenced a cash tender offer at a 
price of $108 per share for all of the outstanding common stock (and the 
associated preferred share purchase rights) of Computer Sciences Corporation.

CSC has approximately 85 million shares outstanding on a fully diluted basis, 
and approximately $700 million of indebtedness, giving the transaction a 
total value of approximately $9.8 billion.  Credit Suisse First Boston 
arranged financing for the acquisition through Bank of America, The Chase 
Manhattan Bank and NationsBank.

The terms and conditions of the offer are set forth in documents filed today 
with the Securities and Exchange Commission.  These documents describe 
conditions to the offer, including the redemption or invalidation of CSC's 
"poison pill" rights plan and the inapplicability of certain anti-takeover 
provisions under Nevada law.

In addition, CA announced today that it has commenced legal action designed 
to compel CSC's Board of Directors to take appropriate steps to permit CSC's 
shareholders to consider the offer.  CA also said it is filing today with the 
Securities and Exchange Commission preliminary materials for solicitation of 
written consents, proxies and agent designations from CSC shareholders that 
are intended to expedite the tender offer.

ISLANDIA, N.Y., February 12, 1998 - Computer Associates International, Inc. 
(CA) received notice today that it has been named as a nominal defendant in a 
class action complaint filed in Clark County, Nevada District Court in 
connection with the Company's offer to acquire Computer Sciences Corporation 
(CSC) for $108 per share.  The Complaint's allegations focus primarily on the 
actions of CSC and its board of directors, all of whom have been named as 
defendants in the lawsuit.

The Complaint alleges that CSC and its board's interests are in conflict with 
the interests of CSC's shareholders.  In particular, the Complaint asserts 
that:

     -    the CSC board has failed and cannot be expected to act in the best 
          interest of CSC's shareholders.
     -    the CSC board members have clear and material conflicts of interest.
     -    the CSC board members are using their positions to better their own   
          interests at the expense of CSC's shareholders.

The Complaint seeks the appointment of a special committee of the CSC board to
consider the CA offer and negotiate with CA on behalf of the CSC shareholders.

CA yesterday announced that it had made an offer to acquire CSC in a merger 
transaction in which CSC's shareholders would receive $108 in cash for each 
share of CSC common stock.  CA has obtained financing commitments for the 
approximately $9 billion transaction.  The combined companies would employ 
over 50,000 professionals and have revenues of approximately $11 billion.

To CA's Valued Channel and Systems Integration Partners:

As you probably know by now, CA has extended an offer to acquire Computer
Sciences Corporation in a merger transaction.  While the completion of this
transaction is by no means certain, we remain hopeful that we will be
successful.

<PAGE>

This is an extremely exciting announcement for everyone involved, as it will 
enable us to deliver superior products, along with unparalleled services and 
support, to our clients and prospects.  The combination of CA and CSC will 
create a world-class information technology solutions company that will 
generate new opportunities for everyone associated with the CA family.  It 
will also provide significant benefit to our Channel and Systems Integration 
Partners by providing new and expanded opportunities.

CA recognizes and values the strategic partnerships we have formed with you 
over the years, and we have no intention of changing the way we do business 
with you. As we see it, a combined CA/CSC would generate ever more demand for 
our products.  With your unique sales and services expertise, you will be 
able to benefit greatly from substantially expanded business opportunities, 
as well as a larger pool of resources at CA that will be focused on 
supporting your marketing and sales needs.

In conclusion, I want to reassure you that we remain committed to providing 
the support you need to meet your clients' most complex information 
management challenges, while helping you increase your bottom line.

Thank you for your continued dedication and support.  We look forward to 
expanding our business opportunities together.

             Open Letter To All Computer Sciences Corporation Employees

                                                            February 11, 1998
To All CSC Employees,

As you may have already heard, Computer Associates announced this morning its 
offer to acquire Computer Sciences Corporation in a merger transaction.

We wanted to take a moment today to reassure you as to CA's intentions.  We 
are well aware of the value of each and every CSC employee and will offer 
every employee a position in the combined company.  Therefore, we will not 
have any layoffs as a result of a possible merger.  In fact, we believe that 
CA is the best place to work for any IT professional - we were voted one of 
the "Best Places To Work" three years in a row by ComputerWorld and were 
recently named one 

<PAGE>

of the 100 Best Companies in America for Working Mothers 
in 1997 by Working Mother magazine.

It is our hope that this transaction will be concluded successfully and 
quickly, as we are anxious to welcome all CSC employees to the combined 
company.

We would also like to take this opportunity to emphasize what we consider the 
truly exciting part about this announcement - the incredible potential that 
this merger holds for the clients, employees, and shareholders of CA and CSC. 
 This is a great opportunity for both our organizations.  A combined CA/CSC 
would radically change the services landscape by creating a truly unique 
entity in the IT marketplace today - the only vendor capable of offering 
platform-neutral products and services in an integrated, end-to-end fashion.

CSC's expertise in the areas of management consulting, systems integration, 
and outsourcing make it a natural and complementary fit for an organization 
like CA, which has never really been in the services business but 
increasingly finds that it needs to be.  Conversely, CA's years of experience 
in software development will add great value to CSC's product business.

We remain convinced that this is a great deal for both companies, and we 
truly believe that the combination of CA and CSC would create a world-class 
IT solutions provider with unparalleled depth in both software and services.

We look forward to having the opportunity to welcome each of you to the CA 
family.

Very truly yours,   

/s/ Charles B. Wang                        /s/ Sanjay Kumar

Mr. Van B. Honeycutt
Chairman and CEO
Computer Sciences Corporation
2100 East Grand Avenue
El Segundo, CA  90245

Dear Van,

Charles and I appreciate the significant time you have invested over the last 
few months in the discussions that we have had regarding the combination of 
Computer Associates International, Inc. ("CA") and Computer Sciences 
Corporation ("CSC").  However, we are disappointed that CA and CSC have not 
been able to come to a final resolution.

Consequently, we are writing to offer to acquire CSC in a merger transaction 
in which your stockholders would receive $108 in cash for each share of CSC 
common stock.  We believe our offer presents an extremely attractive 
opportunity for your stockholders, at a price which represents a premium of 
nearly 35% over the closing price of CSC's common stock on the day we 
commenced our discussions in mid-December.  At that time, CSC's stock was 
trading close to its all-time high.

The CA Board of Directors has unanimously approved this offer.  Further, as I 
have previously informed you, CA has obtained the necessary financing 
commitments to consummate this transaction without delay.  As we agreed, the 
combination of CA and CSC would create a world-class information technology 
solutions provider with unparalleled depth in both software and services.  
The combination of CA's strength in software and CSC's services capabilities, 
together with our collective personnel, would create the perfect model for 
the next generation of information technology solutions provider that will 
lead our industry into the next millenium.

As we discussed at our meeting on February 5, and as confirmed by my letter 
of February 6:

     -    We are in general agreement on the need and manner of retaining key 
          managers and employees.  We would supply key managers and employees
          with employment agreements that will provide them with a strong
          incentive to remain with the combined company.

     -    We are in agreement on providing stock option grants to key managers 
          and employees.  This will allow them to participate in the success of
          the combined company, and will further ensure continuity with respect
          to the combined company's commitment to our mutual clients.

     -    We are in agreement that the CSC organization within the combined 
          company will be on equal footing to CA's existing product
          organization.  CA is committed to making sure 

<PAGE>

          that all of the members of the CSC organization are welcomed into the
          combined company with open arms.

     -    We do not expect the combined company to need to reduce any headcount
          to achieve the synergies that a transaction of this size demands. 
          Consequently, as in our last major acquisition of Cheyenne Software,
          we anticipate that all of the valuable CSC employees will be offered
          positions with the combined company.

     -    Beyond the absolute level of staffing, we expect to maintain the 
          current structure of CSC's organization with little change.  As we
          discussed, it would make sense for the CA part of the combined company
          to take over CSC's product development efforts and for CSC, in turn,
          to take over CA's service commitments and efforts.  The inherent
          synergies in this process will allow both the CA and CSC parts of the
          combined company to do what they do best.

     -    We expect to staff new projects with both outside hiring and some 
          redeployment of existing CA staff.  This will allow the combined
          company to aggressively seek new services opportunities.

As we have previously discussed, we have conducted an extensive analysis of CSC
based on public available information.  We believe that CA and CSC may be able
to bridge some of our differences with respect to valuation if CA is given the
opportunity to conduct limited due diligence on CSC's business and operations. 
With CSC's cooperation, our due diligence review can be accomplished within a
week.

Our offer is subject to the execution of a mutually satisfactory merger
agreement containing customary terms and conditions.  We believe that such an
agreement can be negotiated while we are conducting our due diligence review of
CSC.  Our counsel has advised us that an acquisition of CSC by CA should not
encounter regulatory delays.

We look forward to meeting with you to discuss our offer.  We are hopeful your
Board will conclude that your stockholders should not be denied the opportunity
to consider our offer.  We at CA are determined to take every appropriate action
to pursue this transaction.  In view of the importance of this matter, time is
of the essence, and we await your prompt response.

                                   Sincerely,

                                   /s/ Sanjay Kumar

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9
                                     PAGE 2
 
Section references are to the Internal Revenue Code.
 
PURPOSE OF FORM.--A person who is required to file an information return with
the IRS must get your correct TIN to report, for example, income paid to you,
real estate transactions, mortgage interest you paid, the acquisition or
abandonment of secured property, cancellation of debt, or contributions you made
to an IRA. Use Form W-9 to give your correct TIN to the requester (the person
requesting your TIN) and, when applicable, (1) to certify the TIN you are giving
is correct (or you are waiting for a number to be issued), (2) to certify you
are not subject to backup withholding, or (3) to claim exemption from backup
withholding if you are an exempt payee.
 
NOTE:  If a requester gives you a form other than a W-9 to request your TIN, you
must use the requester's form if it is substantially similar to Form W-9.
 
WHAT IS BACKUP WITHHOLDING?--Persons making certain payments to you must
withhold and pay to the IRS 31% of such payments under certain conditions. This
is called "backup withholding." Payments that could be subject to backup
withholding include interest, dividends, broker and barter exchange
transactions, rents, royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not subject to backup
withholding.
 
    If you give the requester your correct TIN, make the proper certifications,
and report all your taxable interest and dividends on your tax return, payments
you receive will not be subject to backup withholding. Payments you receive WILL
be subject to backup withholding if:
 
    1. You do not furnish your TIN to the requester, or
 
    2. The IRS tells the requester that you furnished an incorrect TIN, or
 
    3. The IRS tells you that you are subject to backup withholding because you
did not report all your interest and dividends on your tax return (for
reportable interest and dividends only), or
 
    4. You do not certify to the requester that you are not subject to backup
withholding under 3 above (for reportable interest and dividend accounts opened
after 1983 only), or
 
    5. You do not certify your TIN.
 
    Certain payees and payments are exempt from backup withholding and
information reporting. See below.
 
HOW TO GET A TIN: If you do not have a TIN, apply for one immediately. To apply
for an SSN, get Form SS-5 from your local Social Security Administration office.
Get Form W-7 to apply for an Individual TIN or Form SS-4 to apply for an EIN.
You can get Forms W-7 and SS-4 from the IRS by calling 1-800-TAX-FORM
(1-800-829-3676).
 
    If you do not have a TIN, check the box titled "Applied For" in the space
for the TIN, sign and date the form, and give it to the requester. Generally,
you will then have 60 days to get a TIN and give it to the requester. If the
requester does not receive your TIN within 60 days, backup withholding, if
applicable, will begin and continue until you furnish your TIN.
 
NOTE: CHECKING THE BOX TITLED "APPLIED FOR" ON THE FORM MEANS THAT YOU HAVE
ALREADY APPLIED FOR A TIN OR THAT YOU INTEND TO APPLY FOR ONE SOON.
 
    As soon as you receive your TIN, complete another Form W-9, include your
TIN, sign and date the form, and give it to the requester.
 
PAYEES EXEMPT FROM BACKUP WITHHOLDING
 
Individuals (including sole proprietors) are NOT exempt from backup withholding.
Corporations are exempt from backup withholding for certain payments, such as
interest and dividends.
 
    If you are exempt from backup withholding, you should still complete Form
W-9 to avoid possible erroneous backup withholding. Enter your correct TIN in
Part I, write "Exempt" in Part II, and sign and date the form. If you are a
nonresident alien or a foreign entity not subject to backup withholding, give
the requester a completed FORM W-8, Certificate of Foreign Status.
 
    The following is a list of payees exempt from backup withholding and for
which no information reporting is required. For interest and dividends, all
listed payees are exempt except item (9). For broker transactions, payees listed
in (1) through (13) and a person registered under the Investment Advisers Act of
1940 who regularly acts as a broker are exempt. Payments subject to reporting
under sections 6041 and 6041A are generally exempt from backup withholding only
if made to payees described in items (1) through (7), except a corporation that
provides medical and health care services or bills and collects payments for
such services is not exempt from backup withholding or information reporting.
Only payees described in items (2) through (6) are exempt from backup
withholding for barter exchange transactions and patronage dividends.
 
    (1) A corporation. (2) An organization exempt from tax under section 501(a),
or an IRA, or a custodial account under section 403(b)(7) if the account
satisfies the requirements of section 401(f)(2). (3) The United States or any of
its agencies or instrumentalities. (4) A state, the District of Columbia, a
possession of the United States, or any of their political subdivisions or
instrumentalities. (5) A foreign government or any of its political
subdivisions, agencies, or instrumentalities. (6) An international organization
or any of its agencies or instrumentalities. (7) A foreign central bank of
issue. (8) A dealer in securities or commodities required to register in the
United States or a possession of the United States. (9) A futures commission
merchant registered with the Commodity Futures Trading Commission. (10) A real
estate investment trust. (11) An entity registered at all times during the tax
year under the Investment Company Act of 1940. (12) A common trust fund operated
by a bank under section 584(a). (13) A financial institution. (14) A middleman
known in the investment community as a nominee or listed in the most recent
publication of the American Society of Corporate Secretaries, Inc., Nominee
List. (15) A trust exempt from tax under section 664 or described in section
4947.
 
Payments of dividends and patronage dividends that are generally exempt from
backup withholding include the following:
 
    - Payments to nonresident aliens subject to withholding under section 1441.
 
    - Payments to partnerships not engaged in a trade or business in the United
      States and that have at least one nonresident partner.
 
    - Payments of patronage dividends not paid in money.
 
    - Payments made by certain foreign organizations.
 
    - Section 404(k) payments made by an ESOP.
 
Payments of interest that generally are exempt from backup withholding include
the following:
 
    - Payments of interest on obligations issued by individuals. Note: You may
      be subject to backup withholding if this interest is $600 or more and is
      paid in the course of the payer's trade or business and you have not
      provided your correct TIN to the payer.
 
    - Payments of tax-exempt interest (including exempt-interest dividends under
      section 852).
 
    - Payments described in section 6049(b)(5) to nonresident aliens.
 
    - Payments on tax-free covenant bonds under section 1451.
 
    - Payments made by certain foreign organizations.
 
    - Mortgage interest paid to you.
 
Payments that are not subject to information reporting are also not subject to
backup withholding. For details, see sections 6041, 6041A, 6042, 6044, 6045,
6049, 6050A, and 6050N, and their regulations.
 
PRIVACY ACT NOTICE.--Section 6109 requires you to give your correct TIN to
persons who must file information returns with the IRS to report interest,
dividends, and certain other income paid to you, mortgage interest you paid, the
acquisition or abandonment of secured property, cancellation of debt, or
contributions you made to an IRA. The IRS uses the numbers for identification
purposes and to help verify the accuracy of your tax return. The IRS may also
provide this information to the Department of Justice for civil and criminal
litigation and to cities, states, and the District of Columbia to carry out
their tax laws.
 
    You must provide your TIN whether or not you are required to file a tax
return. Payers must generally withhold 31% of taxable interest, dividends, and
certain other payments to a payee who does not give a TIN to a payer. Certain
penalties may also apply.
 
PENALTIES
 
(1) FAILURE TO FURNISH TIN.--If you fail to furnish your TIN to a requester, you
are subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.
 
(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis that results in no backup
withholding, you are subject to a penalty of $500.
 
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
 
(4) MISUSE OF TINS.--If the requester discloses or uses TINs in violation of
federal law, the requester may be subject to civil and criminal penalties.

                         a wholly owned subsidiary of 

                     Computer Associates International, Inc. 

  CAI Computer Services Corp., a Delaware corporation (the "Purchaser") and a 
wholly owned subsidiary of Computer Associates International, Inc. ("Computer 
Associates"), hereby offers to purchase all outstanding shares of Common 
Stock, par value $1.00 per share (the "Shares"), of Computer Sciences 
Corporation, a Nevada corporation (the "Company"), and (unless and until the 
Purchaser declares that the Rights Condition (as defined below) has been 
satisfied) the associated Series A Junior Participating Preferred Stock 
Purchase Rights (the "Rights") issued pursuant to the Rights Agreement, dated 
as of December 21, 1988, amended and restated as of August 1, 1996 (the 
"Rights Agreement"), between the Company and ChaseMellon Shareholder 
Services, L.L.C., as Rights Agent, at a purchase price of $108 per Share (and 
associated Right), net to the seller in cash, without interest thereon, upon 
the terms and subject to the conditions set forth in the Offer to Purchase, 
dated February 17, 1998 (the "Offer to Purchase"), and in the related Letter 
of Transmittal (which, together with any amendments or supplements thereto, 
collectively constitute the "Offer"). Unless the context otherwise requires, 
(i) all references to Shares shall include the associated Rights and (ii) all 
references to the Rights shall include all benefits that may inure to holders 
of the Rights pursuant to the Rights Agreement. Unless the Rights are 
redeemed prior to the Expiration Date (as defined below) or the Purchaser is 
satisfied, in its sole discretion, that the Rights have been invalidated or 
are otherwise inapplicable to the Offer and the Proposed Merger (as defined 
in the Offer to Purchase), holders of Shares are required to tender one Right 
for each Share tendered in order to effect a valid tender of Shares in 
accordance with the procedures set forth in Section 2 of the Offer to 
Purchase. Unless the Distribution Date (as defined in the Offer to Purchase) 
occurs, a tender of Shares will also constitute a tender of associated 
Rights. 
  On February 2, 1998, the Company publicly announced a two-for-one split of 
the Shares (the "Announced Stock Split") in the form of a 100% stock dividend 
thereon (the "Stock Split Dividend"). The Company further announced that the 
Stock Split Dividend will be payable on March 23, 1998 to holders of Shares 
of record on March 2, 1998. The $108 per Share offered in the Offer has been 
determined based on the Shares without giving effect to the Announced Stock 
Split. Information with respect to the effect of the Announced Stock Split on 
the terms of the Offer is set forth in the Offer to Purchase. 
        -------------------------------------------------------------
          THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 
          MIDNIGHT, NEW YORK CITY TIME, ON MONDAY, MARCH 16, 1998, 
          UNLESS THE OFFER IS EXTENDED. 
        -------------------------------------------------------------
  The Offer is conditioned upon, among other things, (1) there being validly 
tendered and not withdrawn prior to the expiration of the Offer a number of 
Shares, including the Rights associated therewith, which, when added to the 
number of Shares (and Rights) beneficially owned by the Purchaser and its 
affiliates, constitutes a majority of the total number of outstanding Shares 
(and Rights) on a fully diluted basis, (2) the Rights having been redeemed by 
the Board of Directors of the Company or the Purchaser being satisfied, in 
its sole discretion, that the Rights have been invalidated or are otherwise 
inapplicable to the Offer and the Proposed Merger (the "Rights Condition"), 
(3) the Purchaser being satisfied, in its sole discretion, that the Nevada 
Control Share Acquisition Statute (as defined in the Offer to Purchase) is 
inapplicable to the Offer and the Proposed Merger and (4) the Purchaser being 
satisfied, in its sole discretion, that the Nevada Business Combination 
Statute (as defined in the Offer to Purchase) is inapplicable to the Offer 
and the Proposed Merger. The Offer is also subject to other terms and 
conditions contained in the Offer to Purchase. See the Introduction and 
Sections 1, 14 and 15 of the Offer to Purchase. The Offer is not conditioned 
on obtaining financing. 
  The purpose of the Offer is to enable Computer Associates to acquire control 
of, and the entire equity interest in, the Company. The Offer, as the first 
step in the acquisition of the Company, is intended to facilitate the 
acquisition of all of the Shares. 
  Computer Associates intends to continue to seek to negotiate with the 
Company with respect to the acquisition of the Company by Computer 
Associates. The Purchaser reserves the right to amend the Offer upon entry 
into an acquisition agreement or other agreement regarding a business 
combination with the Company or otherwise or to negotiate an acquisition 
agreement or other agreement regarding a business combination with the 
Company not involving a tender offer. 
  The Purchaser expressly reserves the right, in its sole discretion, at any 
time and from time to time, to extend the period during which the Offer is 
open for any reason, including the occurrence of any event specified in 
Section 14 of the Offer to Purchase, by giving oral or written notice of such 
extension to First Chicago Trust Company of New York (the "Depositary"). 
During any such extension, all Shares previously tendered and not withdrawn 
will remain subject to the right of a tendering stockholder to withdraw such 
stockholder's Shares. Subject to the applicable regulations of the Securities 
and Exchange Commission, the Purchaser also expressly reserves the right, in 
its sole discretion, at any time or from time to time, to (i) delay 
acceptance for payment of or, regardless of whether such Shares were 
theretofore accepted for payment, payment for any Shares pending receipt of 
any regulatory or governmental approvals specified in Section 15 of the Offer 
to Purchase, (ii) terminate the Offer (whether or not any Shares have 
theretofore been accepted for payment) if any condition referred to in 
Section 14 of the Offer to Purchase has not been satisfied or upon the 
occurrence of any event specified in Section 14 and (iii) waive any condition 
or otherwise amend the Offer in any respect, in each case, by giving oral or 
written notice of such delay, termination, waiver or amendment to the 
Depositary and, other than in the case of any such waiver, by making a public 
announcement thereof. Any such extension, delay, termination or amendment 
will be followed as promptly as practicable by public announcement thereof, 
and such announcement in the case of an extension will be made no later than 
9:00 a.m., New York City time, on the next business day after the previously 
scheduled Expiration Date. 
  For purposes of the Offer, the Purchaser will be deemed to have accepted 
for payment, and thereby purchased, Shares validly tendered and not withdrawn 
as, if and when the Purchaser gives oral or written notice to the Depositary 
of the Purchaser's acceptance of such Shares for payment pursuant to the 
Offer. In all cases, upon the terms and subject to the conditions of the 
Offer, payment for Shares purchased pursuant to the Offer will be made by 
deposit of the purchase price therefor with the Depositary, which will act as 
agent for tendering stockholders for the purpose of receiving payment from 
the Purchaser and transmitting payment to validly tendering stockholders. 
Under no circumstances will interest on the purchase price for Shares be paid 
by the Purchaser. In all cases, payment for Shares purchased pursuant to the 
Offer will be made only after timely receipt by the Depositary of (i) 
certificates representing Shares (the "Share Certificates") for such Shares 
and, if applicable, certificates representing the associated Rights (the 
"Rights Certificates") for the associated Rights, or, in the case of Shares, 
timely confirmation (a "Book-Entry Confirmation") of the book-entry transfer 
of such Shares and, if applicable, Rights into the Depositary's account at a 
Book-Entry Transfer Facility (as defined in the Offer to Purchase) pursuant 
to the procedures set forth in Section 3 of the Offer to Purchase, (ii) the 
Letter of Transmittal (or a facsimile thereof), properly completed and duly 
executed, with any required signature guarantees, or an Agent's Message (as 
defined in the Offer to Purchase) in connection with a book-entry transfer 
and (iii) any other documents required by the Letter of Transmittal. 
  If, for any reason whatsoever, acceptance for payment of any Shares and 
Rights tendered pursuant to the Offer is delayed, or the Purchaser is unable 
to accept for payment or pay for Shares and Rights tendered pursuant to the 
Offer, then, without prejudice to the Purchaser's rights set forth in the 
Offer to Purchase, the Depositary may, nevertheless, on behalf of the 
Purchaser and subject to Rule 14e-1(c) under the Securities Exchange Act of 
1934, as amended (the "Exchange Act"), retain tendered Shares and Rights and 
such Shares and Rights may not be withdrawn except to the extent that the 
tendering stockholder is entitled to and duly exercises withdrawal rights as 
described in Section 4 of the Offer to Purchase. Any such delay will be by an 
extension of the Offer to the extent required by law. 
  If certain events occur, the Purchaser will not be obligated to accept for 
payment or pay for any Shares tendered pursuant to the Offer. If any tendered 
Shares are not purchased pursuant to the Offer for any reason or if Share 
Certificates are submitted representing more Shares than are tendered, Share 
Certificates representing unpurchased or untendered Shares will be returned, 
without expense to the tendering stockholder (or, in the case of Shares 
delivered by book-entry transfer into the Depositary's account at a 
Book-Entry Transfer Facility pursuant to the procedures set forth in Section 
3 of the Offer to Purchase, such Shares will be credited to an account 
maintained within such Book-Entry Transfer Facility), as promptly as 
practicable following the expiration, termination or withdrawal of the Offer. 
In the event separate Rights Certificates are issued, similar action will be 
taken with respect to unpurchased and untendered Rights. 
  Except as otherwise provided in Section 4 of the Offer to Purchase, tenders 
of Shares and Rights made pursuant to the Offer are irrevocable. Shares and 
Rights tendered pursuant to the Offer may be withdrawn at any time on or 
prior to the Expiration Date and, unless theretofore accepted for payment as 
provided in the Offer to Purchase, may also be withdrawn at any time after 
April 17, 1998 (or such later date as may apply in case the Offer is 
extended). The term "Expiration Date" means 12:00 midnight, New York City 
time, on Monday, March 16, 1998, unless and until the Purchaser, in its sole 
discretion, shall have extended the period of time for which the Offer is 
open, in which event the term "Expiration Date" shall mean the time and date 
at which the Offer, as so extended by the Purchaser, shall expire. A 
withdrawal of Shares will also constitute a withdrawal of the associated 
Rights. Rights may not be withdrawn unless the associated Shares are also 
withdrawn. In order for a withdrawal to be effective, a written or facsimile 
transmission notice of withdrawal must be timely received by the Depositary 
at one of its addresses set forth on the back cover of the Offer to Purchase. 
Any such notice of withdrawal must specify the name of the person who 
tendered the Shares and Rights to be withdrawn, the number of Shares and 
Rights to be withdrawn, and (if Share Certificates and Rights Certificates 
have been tendered) the name of the registered holder of the Shares and 
Rights as set forth in the Share Certificate and Rights Certificate, if 
different from that of the person who tendered such Shares and Rights. If 
Share Certificates and Rights Certificates have been delivered or otherwise 
identified to the Depositary, then prior to the physical release of such 
certificates, the tendering stockholder must submit the serial numbers shown 
on the particular certificates evidencing the Shares and Rights to be 
withdrawn and the signature on the notice of withdrawal must be guaranteed by 
a firm that is a bank, broker, dealer, credit union, savings association or 
other entity which is a member in good standing of the Securities Transfer 
Agents Medallion Program (an "Eligible Institution"), except in the case of 
Shares and Rights tendered for the account of an Eligible Institution. If 
Shares and Rights have been tendered pursuant to the procedures for 
book-entry transfer set forth in Section 3 of the Offer to Purchase, the 
notice of withdrawal must specify the name and number of the account at the 
appropriate Book-Entry Transfer Facility to be credited with the withdrawn 
Shares and Rights, in which case a notice of withdrawal will be effective if 
delivered to the Depositary by any method of delivery described in this 
paragraph. Withdrawals of Shares and Rights may not be rescinded. Any Shares 
and Rights properly withdrawn will be deemed not validly tendered for 
purposes of the Offer, but may be retendered at any subsequent time prior to 
the Expiration Date by following any of the procedures described in Section 3 
of the Offer to Purchase. All questions as to the form and validity 
(including time of receipt) of notices of withdrawal will be determined by 
the Purchaser, in its sole discretion, whose determination shall be final and 
binding. 
  The information required to be disclosed pursuant to Rule 14d-6(e)(1)(vii) 
of the General Rules and Regulations under the Exchange Act is contained in 
the Offer to Purchase and is incorporated herein by reference. 
  Requests are being made to the Company pursuant to Rule 14d-5 under the 
Exchange Act for the use of the Company's stockholder list, its list of 
holders of Rights and security position listings for the purpose of 
disseminating the Offer to holders of Shares. Upon compliance by the Company 
with such request, the Offer to Purchase and the related Letter of 
Transmittal and, if required, other relevant materials will be mailed to 
record holders of Shares and Rights and will be furnished to brokers, 
dealers, commercial banks, trust companies and similar persons whose names, 
or the names of whose nominees, appear on the stockholder list and list of 
holders of Rights, if applicable, or who are listed as participants in a 
clearing agency's security position listing for subsequent transmittal to 
beneficial owners of Shares and Rights. 
  The Offer to Purchase and the Letter  of Transmittal contain important 
information which should be read carefully before any decision is made with 
respect to the Offer. 
  Questions and requests for assistance may be directed to the Information 
Agent or the Dealer Manager at their respective addresses and telephone 
numbers set forth below. Copies of the Offer to Purchase, the Letter of 
Transmittal and other tender offer materials may be obtained at the 
Purchaser's expense from the Information Agent or from brokers, dealers, 
commercial banks and trust companies. No fees or commissions will be payable 
by the Purchaser to any broker, dealer or other person (other than the 
Information Agent and the Dealer Manager) for soliciting tenders of Shares 
and Rights pursuant to the Offer.

               Re:  Amended and Restated Commitment Letter
                    Proposed Acquisition Credit Facilities

Ladies and Gentlemen:

          We understand that you (the "Borrower") intend to (a) form a
corporation ("AcquisitionCo") to acquire (the "Acquisition") all of the issued
and outstanding capital stock of a company which you have identified to us as
"Saturn" ("Saturn") and (b) as promptly as is practicable following the
consummation of the Acquisition, merge Saturn with and into AcquisitionCo, such
that the surviving entity of such merger is a wholly-owned subsidiary of the
Borrower (the "Merger"; together with the Acquisition, the "Transaction").  We
further understand that the Acquisition may include an unsolicited (i.e.
"hostile") tender offer for all of the issued and outstanding capital stock of
Saturn.

          You have informed Credit Suisse First Boston ("CSFB"), Bank of America
National Trust & Savings Association, The Chase Manhattan Bank and NationsBank,
N.A. (collectively, the "Underwriters") that the total consideration for the
Transaction (including transaction fees and expenses) will be approximately
$12.6 billion and that a portion of such consideration will be financed through
(a) the issuance and sale by the Borrower of approximately $2.75 billion of
senior notes (the "Senior Notes") of the Borrower and (b) existing cash on hand
of not less than $100.0 million.  We further understand that the Borrower will
require up to $10.0 billion in senior credit facilities (the "Credit
Facilities") in order to (w) finance the remainder of the consideration for the
Transaction, (x) refinance certain existing indebtedness of the Borrower and its
subsidiaries (after giving effect to the Transaction), (y) provide working
capital for the Borrower and its subsidiaries and (z) pay fees and expenses in
connection with the transactions contemplated hereby.

          CSFB is pleased to inform you of its commitment to provide up to $2.8
billion of the Credit Facilities and each other Underwriter is pleased to inform
you of its commitment to provide up to $2.4 billion of the Credit Facilities. 
Attached as Exhibit A to this letter is a Statement of Terms and Conditions (the
"Term Sheet") setting forth the principal terms and conditions on and subject to
which each Underwriter is willing to make available its portion of the Credit
Facilities.  The commitments of the Underwriters hereunder are several (and not
joint).  It is a condition to commitment of each Underwriter hereunder that the
portion of the Credit Facilities not being provided by such Underwriter shall be
provided by the other Underwriters.  

          This Amended and Restated Commitment Letter supersedes in all respects
the Commitment Letter, dated February 4, 1998 (the "Original Letter"), from us
to you with respect to the Transaction.  From and after the date hereof, our
commitments and agreements under the Original Letter shall be terminated and the
Original Letter shall be of no further force and effect.

          The terms and conditions of commitments of the Underwriters hereunder
and of the Credit Facilities are not limited to those set forth herein and in
the Term Sheet, and any matters that are not covered by the provisions hereof
and of the Term Sheet shall be subject to our mutual agreement.  We shall be
entitled, after consultation with you, to change the 

<PAGE>

pricing, terms and structure of the Credit Facilities after March 15, 1998 if
the syndication has not been completed and if we determine that such changes are
advisable to insure a successful syndication of the Credit Facilities; provided
that the total amount of the Credit Facilities remain unchanged.

          It is agreed that (a) CSFB will act as the sole Administrative Agent
and Arranger for the Credit Facilities and (b) each other Underwriter (or an
affiliate thereof) will act as a Syndication Agent (in such capacity, the
"Syndication Agents") for the Credit Facilities.  CSFB and the Syndication
Agents shall develop with you a syndication strategy for the Credit Facilities
and, in its capacity as arranger of the Credit Facilities, CSFB shall have the
primary responsibility for coordinating the syndication of the Credit
Facilities.  No additional agents or co-agents or arrangers shall be appointed
without the prior written consent of the Administrative Agent and the
Syndication Agents.  You hereby agree that, in providing the services
contemplated by this letter, the Administrative Agent and each Syndication Agent
(and their respective affiliates) may share among themselves and with the
Administrative Agent and the Syndication Agents (and their respective
affiliates) such confidential or other information relating to the Borrower, its
subsidiaries and investments and the Transaction as from time to time may be in
their possession; provided that each recipient of such information shall agree
to maintain the confidentiality thereof in accordance with its customary
practice.

          The Administrative Agent and the Syndication Agents intend to
syndicate the Credit Facilities to a group of financial institutions (together
with the Underwriters, the "Lenders") identified by us in consultation with you.
We currently intend to commence syndication efforts promptly upon your
commencement of a tender offer for Saturn or, if earlier, the date upon which
you enter into a definitive merger agreement with Saturn regarding the
consummation of the Transactions (it being understood that we reserve the right
to commence syndication earlier or later, if we so elect).  You agree to assist
us in forming any such syndicate and to provide the Underwriters and the other
Lenders, promptly upon request, with all information reasonably requested by
them to complete successfully the syndication, including, but not limited to,
(a) an information package for delivery to potential syndicate members and
participants (the "Information Memorandum") and (b) information and projections
(together with the assumptions utilized in preparing such projections) prepared
by you or your advisers relating to the transaction described herein.  You also
agree to use your best efforts to ensure that our syndication efforts benefit
from the existing lending relationships of the Borrower and, to the extent
practicable, Saturn.  You further agree to make appropriate senior officers and
representatives of the Borrower and, to the extent practicable, Saturn available
to participate in information meetings for potential syndicate members and
participants at such times and places as the Administrative Agent (in
consultation with the Syndication Agents) may reasonably request.

          You represent and warrant and covenant that:

          (a) all information (other than any financial projections contemplated
     by clause (b) below) which has been or is hereafter made available to the
     Administrative Agent or any Syndication Agent by you or any of your
     representatives in connection with the transaction contemplated hereby is
     and will be complete and correct in all material respects and does not and
     will not contain any untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements contained therein
     not materially misleading in light of the circumstances under which such
     statements are made; and

          (b) all financial projections that have been or are hereafter prepared
     by you or on your behalf and made available to the Administrative Agent,
     any Underwriter or any other participant in the Credit Facilities have been
     or will be prepared in good faith based upon assumptions believed by you to
     have been reasonable when made and disclosed therein.

We recognize that changes in the Borrower, Saturn and the Transaction may cause
the representations and warranties made in clause (a) above to cease to be
accurate.  You hereby agree that you will promptly supplement the information
and projections referred to in clauses (a) and (b) above from time to time until
completion of the syndication so that the representations and warranties in the
preceding sentence remain correct.  In arranging and syndicating the Credit
Facilities, the Administrative Agent and the Syndication Agents will use and
rely on such information and projections without independent verification
thereof.

          In connection with the syndication of the Credit Facilities, the
Administrative Agent and the Syndication Agents may, in their discretion,
allocate to other Lenders portions of any fees payable to them and the
Underwriters in connection with the Credit Facilities.  You agree that no Lender
will receive any compensation of any kind for its participation in the Credit
Facilities, except as expressly provided for in this letter or as we shall
otherwise agree.

          The commitment of each Underwriter hereunder is subject to (a) there
not occurring or becoming known to 

                                      2

<PAGE>

us any material adverse condition or material adverse change in or affecting, or
material adverse information with respect to, the business, operations,
property, condition (financial or otherwise) or prospects of the Borrower and
its subsidiaries taken as a whole or of Saturn and its subsidiaries taken as
whole, (b) our completion of and satisfaction in all respects with a due
diligence investigation of publicly available information with respect to Saturn
and its subsidiaries (it being understood that such due diligence shall be
deemed to have been satisfactory to us and this condition shall be deemed to
have been satisfied unless any of us notifies you in writing to the contrary on
or prior to 5:00 p.m., New York City time, on Tuesday, February 24, 1998), (c)
there not having occurred a material disruption of or material adverse change in
financial, banking or capital market conditions that, in our judgment, could
materially impair the syndication of the Credit Facilities, (d) our satisfaction
that prior to and during the syndication of the Credit Facilities there shall be
no competing offering, placement or arrangement of any debt securities (other
than the Senior Notes) or bank financing by or on behalf of the Borrower, any
affiliate or subsidiary thereof or, to the extent that you have control thereof,
Saturn or any subsidiary thereof, (e) the negotiation, execution and delivery of
definitive documentation with respect to the Credit Facilities satisfactory to
the Underwriters and their counsel on or before April 30, 1998 and the
occurrence of the initial borrowing of Term Loans under the Credit Facilities on
or before the date which is 180 days after the earlier of (i) such execution and
delivery and (ii) the date upon which you commence any tender offer relating to
the Acquisition and (f) the other conditions set forth or referred to in the
Term Sheet.  Additionally, it shall be a condition to our respective commitments
hereunder that (x) the definitive documents to be filed with the Securities and
Exchange Commission with respect to the commencement of any tender offer shall
be provided to us prior to the commencement of such tender offer and that all
matters relating to the Credit Facilities and the financing of the Transaction
shall be in form and substance reasonably acceptable to us and (y) we shall not
be required to execute and deliver the definitive credit agreement prior to the
date which is 20 business days after the commencement of our syndication
efforts.

          The reasonable costs and expenses (including, without limitation, the
fees and expenses of a single counsel to the Administrative Agent and the
Syndication Agents, any appropriate local counsel and the syndication and other
out-of-pocket expenses of the Administrative Agent and each Syndication Agent)
arising in connection with the preparation, execution and delivery of this
letter and the definitive financing agreements shall be for your account.  You
further agree to indemnify and hold harmless the Administrative Agent, each
Syndication Agent and each Lender (including the Underwriters) and each
director, officer, employee, affiliate and agent thereof (each, an "indemnified
person") against, and to reimburse each indemnified person, upon its demand,
for, any losses, claims, damages, liabilities or other expenses ("Losses") to
which such indemnified person may become subject insofar as such Losses arise
out of or in any way relate to or result from the Transaction, this letter or
the financing contemplated hereby, including, without limitation, Losses
consisting of legal or other expenses incurred in connection with investigating,
defending or participating in any legal proceeding relating to any of the
foregoing (whether or not such indemnified person is a party thereto); provided
that the foregoing will not apply to any Losses to the extent they are found by
a final decision of a court of competent jurisdiction to have resulted from the
gross negligence or willful misconduct of, or the breach of this Commitment
Letter by, such indemnified person.  The obligations of the Borrower under this
paragraph shall remain effective whether or not definitive financing
documentation is executed and notwithstanding any termination of this letter. 
None of the Administrative Agent, any Syndication Agent, any Underwriter or any
other indemnified person shall be responsible or liable to any other person for
consequential damages which may be alleged as a result of this letter or the
financing contemplated hereby and neither any Underwriter nor any other
indemnified person shall be responsible or liable for any damages which may be
alleged as a result of its failure, in accordance with the terms of this letter,
to provide the Credit Facilities.

          You acknowledge that each Underwriter and its respective affiliates
(the term "Underwriter" being understood to refer hereinafter in this paragraph
to include such affiliates) may be providing debt financing, equity capital or
other services (including financial advisory services) to other companies in
respect of which you may have conflicting interests regarding the transactions
described herein and otherwise.  No Underwriter will use confidential
information obtained from you by virtue of the transactions contemplated by this
Commitment Letter or their other relationships with you in connection with the
performance by such Underwriter of services for other companies, and such
Underwriter will not furnish any such information to other companies.  You also
acknowledge that such Underwriter has no obligation to use in connection with
the transactions contemplated by this Commitment Letter, or to furnish to you,
confidential information obtained by it from other companies.

          This Commitment Letter shall not be assignable by you without the
prior written consent of each Underwriter (and any purported assignment without
such consent shall be null and void), is intended to be solely for the benefit
of the parties hereto and is not intended to confer any benefits upon, or create
any rights in favor of, any person other than the parties hereto.  This
Commitment Letter may not be changed except pursuant to a writing signed by each
of the parties hereto or thereto, as the case may be.  This letter shall be
governed by, and construed in accordance with, the laws of the State of New
York.

                                      3

<PAGE>

          You agree that neither this letter, nor any of its terms or substance,
shall be disclosed, directly or indirectly, to any other person except (a) to
Saturn, (b) to such of your employees, agents and advisers who are directly
involved in the consideration of this matter, (c) as disclosure may be compelled
in a judicial or administrative proceeding or as otherwise required by law and
(d) pursuant to your Press Release dated February 11, 1998; provided that you
may freely disclose this letter, and its terms and substance, at any time
following your acceptance hereof.

          The compensation, reimbursement, indemnification and confidentiality
provisions contained herein shall remain in full force and effect regardless of
whether definitive financing documentation shall be executed and delivered and
notwithstanding the termination of this Commitment Letter or the commitment of
any Underwriter hereunder.

          If you are in agreement with the foregoing, please sign and return to
CSFB the enclosed copies of this letter by no later than Sunday, February 15,
1998.  This offer shall terminate at such time unless prior thereto we shall
have received signed copies of such letters.

          We look forward to working with you on this transaction.

                           $10.0 Billion Credit Facilities

                          Statement of Terms and Conditions

                                  February 15, 1998

An acquisition vehicle ("AcquisitionCo") to be organized by Computer Associates
International, Inc., a Delaware corporation (the "Borrower"), intends to acquire
(the "Acquisition") all of the issued and outstanding capital stock of a company
identified as "Saturn" ("Saturn") and, in connection therewith, to merge Saturn
with and into AcquisitionCo (the "Merger"; together with the Acquisition, the
"Transaction").  In order to finance the Transaction and the continuing
operations of the Borrower and its subsidiaries, the Borrower will require up to
$12.75 billion in financing, to be comprised of (a) $10.0 billion in senior
credit facilities (the "Credit Facilities) and (b) $2.75 billion in senior notes
(the "Senior Notes").  Set forth below is a statement of the terms and
conditions for the Credit Facilities:

I.   Parties.

Borrower: Computer Associates International, Inc., a Delaware corporation (the
          "Borrower").

Guarantors:    All direct and indirect Material Subsidiaries (both before and
               after giving effect to the Transaction) of the Borrower from time
               to time (each, a "Guarantor"; together with the Borrower, the
               "Credit Parties") shall guarantee the Credit Facilities.

               For purposes hereof, the term "Material Subsidiary" shall  mean
               AcquisitionCo and each other subsidiary of the Borrower which (a)
               holds any capital stock of the Borrower, (b) in the aggregate
               with its subsidiaries, has consolidated revenues for the trailing
               four quarters which are in excess of 1% of the consolidated
               revenues of the Borrower and its subsidiaries taken as a whole or

               organized under the laws of a jurisdiction outside the United
               States if the giving of such guarantee would be reasonably likely
               to result in adverse tax consequences to the Borrower or to such

               the first such drawing to occur on the Closing Date and the
               second drawing to occur on the date (which shall be not later

               A Facility at any time when the Interim Facility has not been
               fully drawn.

Amortization:  The Tranche A Facility shall amortize in quarterly installments
               to be mutually agreed upon, with the final installment thereof
               being due and payable on the fifth anniversary of the Effective
               Date.

                              Facility"; together with the Term Loan Facilities,
                              the "Credit Facilities").

                    agreed upon by the Borrower, the Syndication Agents and the

                                             2

<PAGE>

                    available for the issuance of letters of credit (the 
                    "Letters of Credit") by Credit Suisse First Boston or 
                    such other Lender as may be mutually agreed
                    upon by the Borrower and the Administrative Agent (the
                    "Issuing Lender").  No Letter of Credit shall have an
                    expiration date after the date which is five business days
                    prior to the Termination Date.  Drawings under any Letter of
                    Credit shall be reimbursed by the Borrower (whether with its
                    own funds or with the proceeds of loans under the Revolving
                    Credit Facility) on the same business day.  To the extent
                    that the Borrower does not so reimburse the Issuing Lender,
                    the Lenders under the Revolving Credit Facility shall be
                    irrevocably and unconditionally obligated to reimburse the
                    Issuing Lender on a pro rata basis.

Swing Line Loans:   A portion of the Revolving Credit Facility not in excess of
                    $25.0 million shall be available for swing line loans (the
                    "Swing Line Loans") from Credit Suisse First Boston on
                    same-day notice.  Any such Swing Line Loans will reduce
                    availability under the Revolving Credit Facility (other than
                    for purposes of determining the commitment fee) on a
                    dollar-for-dollar basis.  Each Lender under the Revolving
                    Credit Facility shall acquire, under certain circumstances,
                    an irrevocable and unconditional pro rata participation in
                    each such Swing Line Loan.

Maturity: The Termination Date.

Purpose:            The proceeds of the loans under the Revolving Credit
                    Facility shall be used by the Borrower and its subsidiaries
                    for working capital and other general corporate purposes
                    (including, without limitation, for the same purposes as the
                    Term Loan Facilities).

III. General Provisions.

Interest Rate Options:The Borrower may elect that all or a portion of the loans 
          under the Credit Facilities (collectively, the "Loans"), bear interest
          at a rate per annum equal to:

                    (a)  The higher of (1) the rate of interest publicly
                         announced by Credit Suisse First Boston as its base
                         lending rate for commercial loans in US Dollars in the
                         United States and (2) the federal funds rate from time
                         to time plus 0.5% (such highest rate, the "Base Rate";
                         the base lending rate is not intended to be the lowest
                         rate charged by Credit Suisse First Boston to its
                         borrowers) plus the Applicable Margin (as hereinafter
                         defined) which is then in effect; or

                    (b)  The rate (grossed-up for maximum statutory reserve
                         requirements for eurodollar liabilities) reflected on
                         the Telerate service (other similar service) as the
                         "British Bankers' Association Settlement Rate" for
                         eurodollar deposits for one, two, three or six (as
                         selected by the Borrower)(the "Eurodollar Rate") plus
                         the Applicable Margin which is then in effect.

                    For purposes hereof, the term "Applicable Margin" shall mean
                    (a) initially, 1-3/4% per annum in the case of Eurodollar
                    Loans and 3/4 of 1% per annum in the case of Base Rate Loans
                    and (b) for each day from and after the later of the date
                    which is six months after the Closing Date and the date upon
                    which the Interim Facility has been repaid in full, the rate
                    per annum set forth below opposite the lowest public debt
                    rating then in effect for the senior, unsecured, long-term
                    indebtedness of the Borrower:

                         Base Rate ("Base Rate Loans"), in arrears on the last
                         business day of each calendar quarter.

                    In the case of loans bearing interest based upon the
                    Eurodollar Rate ("Eurodollar Loans"), on the last day of
                    each relevant interest period and, in the case of any
                    interest period longer than three months, on each successive
                    date three months after the first day of such interest
                    period.

                    In addition, any payment of principal of Loans (other than
                    of Loans under the Revolving Credit Facility) shall be
                    accompanied by interest then owing on the amount so paid.

Letter of Credit Fees:   The Borrower shall pay a commission on all outstanding
                         Letters of Credit at a per annum rate equal to the
                         Applicable Margin then in effect with respect to
                         Eurodollar Loans under the Revolving Credit Facility on
                         the face amount of each such Letter of Credit.  Such
                         commission shall be shared ratably among the Lenders
                         participating in the Revolving Credit Facility and
                         shall be payable quarterly in arrears.

                    A fronting fee equal to 1/4 of 1% per annum on the face
                    amount of each Letter of Credit shall be payable quarterly
                    in arrears to the Issuing Lender for its own account.  In
                    addition, customary administrative, issuance, amendment,
                    payment and negotiation charges shall be payable to the
                    Issuing Lender for its own account.

Default Rate:       During the continuance of an Event of Default, outstanding
                    Loans will bear interest at the rate which is 2% over the
                    rate otherwise applicable thereto.

Reserve Requirements;
Yield Protection:   The rate quoted as the Eurodollar Rate will be grossed-up
                    for the maximum reserve requirements prescribed for
                    eurocurrency liabilities.  In addition, the financing
                    agreements will contain customary provisions relating to
                    increased costs, capital adequacy protection, withholding
                    and other taxes and illegality.

Commitment Fee:     The Borrower shall pay a commitment fee quarterly, in
                    arrears, on the average daily undrawn amount (without giving
                    effect to any drawings of Swing Line Loans) of the Revolving
                    Credit Facility.  Such commitment fee shall accrue at the
                    rate equal to (a) initially, 3/8 of 1% per annum and (b) for
                    each day from and after the later of the date which is six
                    months after the Closing Date and the date upon which the
                    Interim Facility has been repaid in full, the rate per annum
                    set forth below opposite the lowest public debt rating then
                    in effect for the senior, unsecured, long-term indebtedness
                    of the Borrower:

                    of the Eurodollar Rate and any rate based upon the Federal
                    Funds Rate; otherwise, 365/6 days for actual days elapsed.

Optional Prepayments and
Commitment Reductions:   Loans may be prepaid and commitments may be reduced by
                         the Borrower without premium or penalty (but subject to
                         Eurodollar breakage indemnities), in minimum amounts to
                         be agreed upon.  Any such optional prepayments of Term
                         Loans shall be made, first, to the Interim Facility
                         and, second, to the Tranche A Facility.

Mandatory Prepayments
and Commitment
Reductions:         The Credit Facilities shall be reduced with (a) 100% of the
                    net proceeds of asset sales by the Borrower and its
                    subsidiaries (subject to a right of reinvestment and other
                    exceptions to be mutually agreed upon), (b) 100% of the net
                    proceeds from the incurrence of debt by the Borrower and its
                    subsidiaries (other than certain working capital
                    indebtedness for foreign subsidiaries and other exceptions
                    to be mutually agreed upon) and (c) 100% of the net proceeds
                    from the offering and sale of equity by the Borrower and its
                    subsidiaries.  All such reductions shall be applied, first,
                    to prepay the Interim Facility, second, to prepay ratably
                    the remaining installments of the Tranche A Facility and,
                    third, to reduce the Revolving Credit Facility (and, to the
                    extent necessary, to repay the loans and cash collateralize
                    the Letters of Credit outstanding thereunder).  In addition,
                    the Interim Facility shall be reduced by the amount by which
                    the aggregate principal amount of the Senior Notes exceeds
                    $2.75 billion.

                    Notwithstanding the foregoing, the mandatory prepayments and
                    commitment reductions described above shall terminate upon
                    the satisfaction of performance tests to be mutually agreed
                    upon by the Borrower, the Syndication Agents and the
                    Administrative Agent.

                         assignment amount shall be $5.0 million unless
                         otherwise agreed by the Borrower and the Administrative
                         Agent.  Participants shall have the same benefits as
                         the Lenders with respect to yield protection and
                         increased cost provisions.  Voting rights of
                         participants shall be limited to those matters with
                         respect to which the affirmative vote of the Lender
                         from which it purchased its participation would be
                         required as described under "Voting" above.  Pledges of
                         Loans in accordance with applicable law shall be
                         permitted without restriction.  Promissory notes shall
                         be issued under the Credit Facilities only upon request
                         of the relevant Lender and will be provided 45 days
                         after the Closing Date.

Yield Protection:        The Credit Documentation shall contain customary
                         provisions (a) protecting the Lenders against increased
                         costs or loss of yield resulting from changes in
                         reserve, tax, capital adequacy and other requirements
                         of law and from the imposition of or changes in
                         withholding or other taxes and (b) indemnifying the
                         Lenders for "breakage costs" incurred in connection
                         with, among other things, any prepayment of a
                         Eurodollar Loan on a day other than the last day of an
                         interest period with respect thereto.

Expenses and 
Indemnification:         The Borrower shall pay (a) all reasonable out-of-pocket
                         expenses of the Administrative Agent and the
                         Syndication Agents associated with the syndication of
                         the Credit Facilities and the preparation, execution,
                         delivery and administration of the Credit Documentation
                         and any amendment or waiver with respect thereto
                         (including the reasonable fees, disbursements and other
                         charges of a single counsel to the Administrative Agent
                         and the Syndication Agents and any necessary local
                         counsel) and (b) all out-of-pocket expenses of the
                         Administrative Agent and the Lenders (including the
                         fees, disbursements and other charges of counsel) in
                         connection with the enforcement of the Credit
                         Documentation.

                         The Administrative Agent, the Syndication Agents and
                         the Lenders (and their affiliates and their respective
                         officers, directors, employees, advisors and agents)
                         will have no liability for, and will be indemnified and
                         held harmless against, any loss, liability, cost or
                         expense incurred in respect of the financing
                         contemplated hereby or the use or the proposed use of
                         proceeds

                         party).
