ITEM 1. SUBJECT COMPANY INFORMATION.

    The name of the subject company to which this Solicitation/Recommendation
Statement on Schedule 14D-9 (the "Schedule 14D-9") relates is Sterling
Software, Inc., a Delaware corporation ("Sterling Software"). The address of the
principal executive offices of Sterling Software is 300 Crescent Court, Suite
1200, Dallas, Texas 75201. The telephone number of the principal executive
offices of Sterling Software is (214) 981-1000. The title of the class of equity
securities to which this Schedule 14D-9 relates is common stock, par value $.10
per share, including the associated preferred stock purchase rights, of Sterling
Software (the "Sterling Software Common Stock" or the "Shares"). As of
February 18, 2000, there were 82,570,327 Shares outstanding.

ITEM 2. IDENTITY AND BACKGROUND OF FILING PERSON.

    The name, business address and business telephone number of Sterling
Software, which is the person filing this Schedule 14D-9, are set forth in Item
1 above.

    The Schedule 14D-9 relates to the offer by Computer Associates
International, Inc., a Delaware corporation ("Computer Associates"), through its
wholly-owned subsidiary, Silversmith Acquisition Corp. ("Silversmith Acquisition
Corp."), a Delaware corporation, disclosed in a tender offer statement on
Schedule TO (the "Schedule TO"), dated February 22, 2000, to exchange each
outstanding Share for 0.5634 shares (the "Exchange Ratio") of common stock, par
value $.10 per share, of Computer Associates (the "Computer Associates Common
Stock"), subject to adjustment as set forth below, upon the terms and subject to
the conditions set forth in the Exchange Offer, dated February 22, 2000 (the
"Exchange Offer"), and in the related Letter of Transmittal (the "Letter of
Transmittal" which, together with the Exchange Offer, as amended or supplemented
from time to time, constitute the "Offer").

    Notwithstanding the foregoing, for purposes of the Offer, the Exchange Ratio
will be adjusted as follows: if the "average Computer Associates trading price"
(as defined herein) (i) is greater than $77.12, then the Exchange Ratio will be
reduced so that each Share tendered in the Offer will be exchanged for such
number of shares of Computer Associates Common Stock as is designed to equal
$43.45 at the time the Exchange Ratio is set based on the average Computer
Associates trading price, or (ii) is less than $63.10, then, unless Computer
Associates elects the Cash Option (as described in the next sentence), the
Exchange Ratio will be increased so that each Share tendered in the Offer will
be exchanged for such number of shares of Computer Associates Common Stock as is
designed to equal $35.55 at the time the Exchange Ratio is set based on the
average Computer Associates trading price. If the average Computer Associates
trading price is less than $63.10, Computer Associates, in its sole discretion,
may elect (the "Cash Option") to reduce the Exchange Ratio that would otherwise
be in effect and pay cash in substitution for Computer Associates' shares for
all or a portion of the shortfall of the average Computer Associates trading
price below $63.10 (the "Cash Option Amount"). For purposes of the Offer,
"average Computer Associates trading price" means the 10-trading day average of
the daily average of the high and low sales price per share of Computer
Associates Common Stock on the New York Stock Exchange, Inc. (the "NYSE")
composite tape ending on the trading day immediately preceding the day on which
the later of (i) the waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), and any other antitrust
laws applicable to the Offer, expire or terminate and (ii) the Registration
Statement on Form S-4 filed in connection with the Offer becomes effective under
the Securities Act of 1933, as amended.

    The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of February 14, 2000 (the "Merger Agreement"), among Computer Associates,
Silversmith Acquisition Corp. and Sterling Software. The Merger Agreement
provides that, among other things, as soon as practicable following the
satisfaction or waiver of the conditions set forth in the Merger Agreement,
Silversmith Acquisition Corp. will be merged with and into Sterling Software
(the "Merger"), and Sterling Software

                                       2
<PAGE>
will continue as the surviving corporation (the "Surviving Corporation"). At the
effective time of the Merger (the "Effective Time"), each Share then outstanding
(other than Shares held by Computer Associates or Silversmith Acquisition Corp.
or stockholders who perfect appraisal rights under Delaware law, which will be
available if Computer Associates elects the Cash Option or if the Merger is
completed pursuant to Section 253 of the Delaware General Corporation Law) will
be converted into the right to receive such number of fully paid and
nonassessable shares of Computer Associates Common Stock as is equal to the
Exchange Ratio finally established for the Offer and, if Computer Associates has
elected the Cash Option in connection with the Offer, an amount in cash equal to
the Cash Option Amount. A copy of the Merger Agreement is filed herewith as
Exhibit (e)(1) and is incorporated herein by reference.

    Copies of the Exchange Offer and the Letter of Transmittal are filed
herewith as Exhibits (a)(1) and (a)(2), respectively, and are incorporated
herein by reference.

    The Schedule TO states that the principal executive offices of Computer
Associates and Silversmith Acquisition Corp. are located at One Computer
Associates Plaza, Islandia, New York, 11749-7000.

ITEM 3. PAST CONTACTS, TRANSACTIONS, NEGOTIATIONS AND AGREEMENTS.

    The information contained under the caption "The Offer--Interests of
Directors and Management in the Proposed Combination" in the Exchange Offer, and
in the Information Statement which is attached hereto as Schedule I, is
incorporated herein by reference. Each material agreement, arrangement or
understanding and any actual or potential conflict of interest between Sterling
Software or its affiliates and (1) Sterling Software's executive officers,
directors or affiliates or (2) Computer Associates or Silversmith Acquisition
Corp. or their respective executive officers, directors or affiliates, is either
incorporated herein by reference as a result of the previous sentence or set
forth below.

    TREATMENT OF OPTIONS.  The Merger Agreement provides that each outstanding
option to purchase Shares which has been granted to certain management
employees, including the executive officers of Sterling Software (a "Management
Option"), shall become fully vested and exercisable immediately prior to the
consummation of the Offer and that Management Options shall be converted into
options to purchase shares of Computer Associates Common Stock upon consummation
of the Offer, unless a holder of a Management Option instead elects to receive a
cash payment as described below. Such conversions shall be accomplished by
multiplying the number of Shares subject to each option by the Option Exchange
Ratio (as defined below) and dividing the exercise price per share of each
option by the Option Exchange Ratio. Although the Merger Agreement provides for
an acceleration of vesting and exercisability immediately prior to the
consummation of the Offer, most of the Management Options, by their terms,
already provided for an acceleration of vesting and exercisability upon a change
in control. The "Option Exchange Ratio" is the sum of the Exchange Ratio plus,
in the event of the Cash Option, the number determined by dividing the Cash
Option Amount by the average Computer Associates trading price.

    The Merger Agreement also provides that each holder of a Management Option
may elect to cancel a Management Option in exchange for a cash payment equal to
the excess of the Cancellation Price (as defined herein) over the per share
exercise price of the Management Option multiplied by the number of Shares
subject to the option. The "Cancellation Price" is equal to the Option Exchange
Ratio multiplied by the average Computer Associates trading price.

    The following table sets forth, with respect to each of the executive
officers and the non-employee directors (as a group) of Sterling Software:

                                       3
<PAGE>
    - the number of Shares subject to options held by such persons that will be
      exercisable immediately prior to the consummation of the Offer (including
      options that are currently exercisable as well as options which became
      exercisable in connection with the transactions contemplated by the Merger
      Agreement);

    - the weighted average exercise price of the options held by such persons;
      and

    - the aggregate cash value of such options based upon an assumed per share
      amount of consideration to be received by Sterling Software stockholders
      in the Offer and the Merger of $39.50 in Computer Associates Common Stock
      (I.E., the total stock value less the exercise price).

- ------------------------

(1) As of February 12, 2000, the following individuals held unvested options in
    the amounts set forth next to their names the vesting of which was
    accelerated as a result of the transactions contemplated by the Merger
    Agreement: F.L. "Mike" Harvey (175,000); Don J. McDermett, Jr. (201,100);
    B. Carole Morton (112,500); Mark A. Theel (134,750); Geno P. Tolari
    (325,000); R. Logan Wray (277,600); and all non-employee directors as a
    group (200,000).

    CHANGE IN CONTROL SEVERANCE AGREEMENTS.  Each of the executive officers, as
well as Mr. Evan A. Wyly, a director of Sterling Software, and certain other
officers of Sterling Software (collectively, the "Executives"), are parties to
change in control severance agreements. Each change in control severance
agreement requires Sterling Software to provide an Executive, upon a qualifying
termination of employment, with a lump sum amount equal to a multiple of the
Executive's annual cash compensation. Each agreement also requires Sterling
Software to continue to provide an Executive, for a certain number of months,
with the benefits and perquisites that were provided to the Executive prior to
the qualifying termination of employment. In addition, the agreements also
provide for an Executive to receive a gross-up payment if the Executive becomes
subject to any excise tax as a result of any payments that the Executive
receives under the agreement, or otherwise, being determined to be "excess
parachute payments."

    As part of the Merger Agreement negotiations, Computer Associates requested
that the change in control severance agreements be amended. In particular,
Computer Associates requested that each Executive waive his or her right to a
continuation of benefits and perquisites (except medical coverages) and that the
agreements be amended to add a non-competition covenant in respect of certain
Executives and non-solicitation and confidentiality covenants in respect of all
the Executives. On February 14, 2000, Sterling Software, Computer Associates and
each Executive agreed to amend the change in control severance agreements,
effective as of the consummation of the Offer. Such amendments, which were
required by Computer Associates as a condition to executing the Merger
Agreement, become effective upon consummation of the Offer. In general, such
amendments confirmed and, in certain respects reduced, the Executives' benefits
and imposed upon the Executives a

                                       4
<PAGE>
non-competition covenant and other covenants to which they were not previously
subject. The amendments provide, among other things, that:

    - each Executive will be paid a lump sum in cash upon a qualifying
      termination of employment in satisfaction of all severance pay and in lieu
      of the continuation of certain benefits and perquisites to which he or she
      would otherwise have been entitled pursuant to such Executive's change in
      control severance agreement. As to certain of the Executives, twenty-five
      percent of the payment is in consideration for entering into a
      non-competition covenant. The payments to be provided to each executive
      officer of Sterling Software and Evan A. Wyly upon a qualifying
      termination of employment are as follows:

    - each Executive must keep Sterling Software information confidential;

    - each Executive is entitled to a gross-up on any excise tax under
      Section 4999 of the Internal Revenue Code of 1986, as amended (the
      "Code"), which may be imposed on any payments and benefits received by the
      Executive in connection with the Offer or the Merger. If the Offer is
      consummated on March 20, 2000, and assuming each Executive were to incur a
      qualifying termination of employment immediately following that date and a
      per share consideration to be received by Sterling Software stockholders
      in the Offer and the Merger of $39.50 in Computer Associates Common Stock,
      the approximate gross-up payments that would be payable to certain
      Executives (those expected to be subject to excise tax) are as follows:

<TABLE>

</TABLE>

    Ms. Morton and Messrs. Tolari and Harvey have each delivered Computer
Associates a letter whereby they have agreed to elect to receive cash
consideration (rather than convert their options) to the extent that failure to
so elect would result in an incremental increase of such individual's excise tax
liability.

    In addition:

    - Mr. Williams' change in control severance agreement has been amended to
      require Sterling Software to transfer to him, upon a qualifying
      termination of employment, the ownership of the life insurance policy
      concerning him which has been funded by Sterling Software;

    - Mr. Sam Wyly's change in control severance agreement has been amended to
      require Sterling Software to pay him, upon a qualifying termination of
      employment, an amount in cash equal to the value of the split dollar life
      insurance policy concerning him which is held by Sterling Software; and

    - Ms. Morton's change in control severance agreement has been amended to
      have Sterling Software acknowledge her entitlement to certain retiree
      medical benefits.

    DEFERRED COMPENSATION PLAN.  Employees with annual compensation from
Sterling Software which exceeds $120,000, as well as all directors and certain
consultants, are eligible to participate in Sterling Software's Deferred
Compensation Plan. Participants in the plan may elect to have their deferrals
deemed invested in one or more funds available under the plan. All amounts in a
participant's account

                                       6
<PAGE>
are 100% vested at all times, provided, that certain penalties apply to certain
unscheduled withdrawals. Participants may defer post-employment payments
(including payments pursuant to the change in control severance agreements)
under the plan.

    Upon termination of employment, a participant's account balance is paid
either in a lump sum payment or in quarterly installments over a certain period
as a participant may elect under the terms of the plan. Upon a change in control
(including the filing by Sterling Software of a Current Report on Form 8-K in
connection with the Merger Agreement), all participants have the right to a
distribution of their account balances in a lump sum or in periodic
distributions as provided in the plan upon six months' notice. If a participant
requests payment without six months notice, the participant will forfeit 10% of
the amount to be distributed.

    EMPLOYEE HEALTH BENEFIT PLAN.  On December 31, 1999, Sterling Software's
Employee Health Benefit Plan (which also provides for retiree medical benefits)
was amended to provide that, following a change in control (including the filing
by Sterling Software of a Current Report on Form 8-K in connection with the
Merger Agreement), the plan may not be amended in a manner which is adverse to
those participants who are eligible for or in receipt of retiree medical
benefits.

    GENO P. TOLARI'S SERP AGREEMENT.  On February 15, 2000, Sterling Software,
Computer Associates and Mr. Tolari entered into an agreement (the "SERP
Agreement") which modified Mr. Tolari's rights under his Supplemental Executive
Retirement Plan II ("SERP II"). Under the SERP Agreement, Mr. Tolari agreed to
receive, within five days after the date that his employment with Sterling
Software is terminated for any reason, a lump sum payment of $3,527,640 in
satisfaction in full for Sterling Software's obligations to him under SERP II.

    MERGER AGREEMENT.  The following is a summary of certain material provisions
of the Merger Agreement. This summary is qualified in its entirety by reference
to the complete text of the Merger Agreement, a copy of which is filed herewith
as Exhibit (e)(1) and is incorporated herein by reference. Capitalized terms not
otherwise defined herein shall have the meanings set forth in the Merger
Agreement.

for Shares had been so converted, exercised or exchanged) as of the date that
Computer Associates accepts the Shares pursuant to the Offer (the "Minimum
Tender Condition"). On February 9, 2000, the number of Shares needed to satisfy
the Minimum Tender Condition would have been 51,457,769.

<PAGE>
    (5) The Offer is also subject to the conditions that, at the time of
acceptance for exchange of Shares pursuant to the Offer:

<PAGE>
      Acquisition Corp. into the Tender Agreement or (2) the Sterling Software
      Board, or any committee thereof, has not recommended to the stockholders
      of Sterling Software any Acquisition Proposal (as defined below) or
      resolved to do so or publicly announced an intention to do so;

    - Sterling Software has not entered into, or publicly announced its
      intention to enter into, an agreement or agreement in principle (other

      Act of 1934 (the "Exchange Act"), other than Computer Associates or any of
      its subsidiaries, has become the beneficial owner, defined in Rule 13d-3
      promulgated under the Exchange Act, of 15% or more of the outstanding
      shares of Sterling Software Common Stock or acquired, directly or
      indirectly, 15% or more of the assets of Sterling Software and its
      subsidiaries.

    The conditions of the Offer described above are for the sole benefit of
Computer Associates and Silversmith Acquisition Corp. and may be asserted by
Computer Associates, regardless of the circumstances giving rise to any such
conditions, including any action or omission by Computer Associates or
Silversmith Acquisition Corp. Computer Associates and Silversmith Acquisition
Corp. may waive these conditions in their reasonable discretion in whole or in
part from time to time (other than the Minimum Tender Condition).

    AMENDING THE OFFER.  Pursuant to the Merger Agreement, Computer Associates
agreed that, without the prior written consent of Sterling Software, no change
may be made to the Offer which:

    - changes the form or amount of consideration to be paid, other than in
      connection with the election of the Cash Option or by adding

      Merger Agreement or which changes or waives the Minimum Tender Condition;

    - extends the Offer, other than as described below; or

    - makes any other change to any condition to the Offer which is adverse to
      the holders of Shares.

    CONSIDERATION.  The Merger Agreement provides for the consideration that
Computer Associates will pay in the Offer, including the Exchange Ratio, the
adjustments to the Exchange Ratio, if any, and the procedures for electing the
Cash Option.

    EXPIRATION OR TERMINATION OF THE OFFER.  Pursuant to the Merger Agreement,
Computer Associates agreed that if, at the scheduled expiration date of the
Offer, the conditions to the Offer shall not have been satisfied or waived,
other than several specified conditions, unless there is no reasonable
possibility of all of the conditions to the Offer being satisfied on or before
September 30, 2000, Computer Associates will extend the expiration date of the
Offer for an additional period or periods of time, each of which being no longer
than 15 business days, until the date that such conditions are satisfied or
waived and Computer Associates becomes obligated to accept for payment and pay
for Shares tendered pursuant to the Offer. However, if at any scheduled
expiration date of the Offer, all of the conditions to the Offer have been
satisfied or waived other than the Minimum Tender Condition, Computer Associates
will only be required to extend the Offer for an additional 20 business days
following such scheduled expiration date.

    THE MERGER.  If the conditions to the Merger are satisfied or waived in
accordance with the Merger Agreement and in accordance with the Delaware General
Corporation Law, at the effective time of the

                                       9
<PAGE>
Merger (the "Effective Time"), Silversmith Acquisition Corp. will merge with
Sterling Software. Sterling Software will survive the Merger as a wholly owned
subsidiary of Computer Associates.

    EFFECTIVE TIME OF THE MERGER.  The Merger will become effective upon the
filing of a certificate of merger with the Delaware Secretary of State or such
later time as is agreed by Computer Associates and Sterling Software and
specified in the certificate of merger. The filing of the certificate of merger
will take place as soon as practicable, but no later than the second business
day, after satisfaction or waiver of the conditions described below under
"--Conditions to the Completion of the Merger" unless the parties agree to
another date.

    ADDITIONAL EFFECTS OF THE MERGER.  Upon completion of the Merger:

    - each outstanding share of capital stock of Silversmith Acquisition Corp.
      will be converted into and become one share of common stock of Sterling
      Software as the corporation surviving the Merger;

    - each outstanding share of Sterling Software Common Stock will be converted
      into and become the right to receive the amount and type of consideration
      received by Sterling Software stockholders who tendered their Shares in
      the Offer;

    - the directors and officers of Silversmith Acquisition Corp. at the
      Effective Time will become the directors and officers of Sterling Software
      as the corporation surviving the Merger;

    - the certificate of incorporation of Sterling Software, as in effect
      immediately prior to the Effective Time, will be amended as of the
      Effective Time so as to (a) reduce the total number of authorized shares
      of capital stock to be 1,000 shares of common stock, par value $.10 per
      share, and (b) permit the stockholders of the corporation to take action
      without a meeting, and, as so amended, such certificate of incorporation
      shall be the certificate of incorporation of Sterling Software as the
      corporation surviving the Merger; and

    - the by-laws of Silversmith Acquisition Corp. at the Effective Time will
      become the by-laws of Sterling Software as the corporation surviving the
      Merger.

    EXCHANGE AGENT.  At the Effective Time, Computer Associates shall enter into
an agreement with a bank or trust company that is reasonably acceptable to
Sterling Software (the "Exchange Agent"), with which Computer Associates shall
deposit any required cash and certificates representing the number of whole
shares of Computer Associates Common Stock issuable pursuant to the Merger
Agreement in exchange for outstanding shares of Sterling Software Common Stock.
Soon after the Effective Time, Computer Associates will send a letter to each
person who was a Sterling Software stockholder at the Effective Time containing
instructions on how to surrender Sterling Software stock certificates to the
Exchange Agent and receive shares of Computer Associates Common Stock and cash,
if any cash is payable.

    DIVIDENDS.  Holders of Shares will not be entitled to receive any dividends
or other distributions payable by Computer Associates until they exchange their
Sterling Software stock certificates for certificates representing shares of
Computer Associates Common Stock. Once holders deliver their Sterling Software
stock certificates to the Exchange Agent, they will receive, subject to
applicable laws, accumulated dividends and distributions, without interest.

    FRACTIONAL SHARES.  No fractional shares of Computer Associates Common Stock
will be issued upon the surrender of certificates representing Shares. No
dividend or other distribution of Computer Associates will relate to any such
fractional shares and no such fractional shares will entitle the owner thereof
to any voting or other rights of a stockholder of Computer Associates. Holders
of Shares otherwise entitled to fractional shares of Computer Associates Common
Stock will receive a cash

                                       10
<PAGE>
payment instead of such fractional shares. Following the Effective Time, the
Exchange Agent will determine the excess of the number of whole shares of
Computer Associates Common Stock delivered to the Exchange Agent by Computer
Associates for distribution to Sterling Software stockholders over the aggregate
number of whole shares of Computer Associates Common Stock to be distributed to
Sterling Software stockholders. The Exchange Agent will then, on behalf of the
former Sterling Software stockholders, sell the excess shares of Computer
Associates Common Stock at then prevailing prices on the NYSE, all in the manner
provided in the Merger Agreement. Notwithstanding the foregoing, Computer
Associates has the option, exercisable prior to the Effective Time, in lieu of
the issuance of such excess shares to pay each former holder of Shares and
amount of cash equal to the product of the fractional share interest to which
such holder would otherwise be entitled and the closing price of Computer
Associates Common Stock on the NYSE on the Effective Time.

    As soon as practicable after the determination of the amount of cash to be
paid to holders of Shares with respect to any fractional share interests, the
Exchange Agent will make available such amounts to such Sterling Software
stockholders subject to and in accordance with the terms of the Merger
Agreement.

    STERLING SOFTWARE BOARD OF DIRECTORS.  Upon acceptance for exchange of
Shares in the Offer, Computer Associates will be entitled to designate a number
of directors of Sterling Software (rounded up to the next whole number) that
bears the same proportion to the total number of directors of Sterling Software
as the proportion of the total number of shares of Sterling Software of Sterling
Software Common Stock then held by Computer Associates bears to the total number
of outstanding shares of Sterling Software Common Stock, provided that until the
Merger has been consummated, the Sterling Software Board shall always have at
least two members (the "Continuing Directors") who were directors of Sterling
Software prior to consummation of the Offer. The Merger Agreement provides that,
prior to the Effective Time, if Computer Associates' designees are elected to
the Sterling Software Board, the affirmative vote of the Continuing Directors
will be required to:

    - amend or terminate the Merger Agreement;

    - waive any of Sterling Software's rights, benefits or remedies under the
      Merger Agreement;

    - extend the time for performance of Computer Associates' or Silversmith
      Acquisition Corp.'s obligations under the Merger Agreement; or

    - approve any other action by Sterling Software which is reasonably likely
      to adversely affect the interests of Sterling Software's stockholders,
      other than Computer Associates and its affiliates, with respect to the
      transactions contemplated by the Merger Agreement.

    OTHER OFFERS.  The Merger Agreement provides that, from the date of the

through advisors, agents or other intermediaries, and will cause its officers,
directors, advisors, representatives and other agents not to, directly or
indirectly:

    - solicit, initiate or knowingly encourage, or take any other action to
      facilitate, any inquiries or the making of any proposal that constitutes,
      or may reasonably be expected to lead to, any Acquisition Proposal;

    - participate or engage in substantive discussions or negotiations with, or
      disclose or provide any non-public information relating to Sterling
      Software or its subsidiaries or afford access to the properties, books or
      records of Sterling Software or its subsidiaries to, any person or entity
      that has made an Acquisition Proposal or with or to any person or entity
      in contemplation of an Acquisition Proposal; or

    - enter into any agreement or agreement in principle providing for or
      relating to an Acquisition Proposal.

                                       14
<PAGE>
PROVIDED, HOWEVER, that if and only if:

    - a person has submitted an unsolicited Acquisition Proposal to the Sterling
      Software Board under circumstances in which Sterling Software has complied
      with its obligations under Merger Agreement relating to other offers;

    - the Sterling Software Board believes in good faith, based on such matters
      as it deems relevant, including the advice of its financial advisor, that
      such unsolicited Acquisition Proposal is a Superior Proposal (as defined
      below); and

    - the Sterling Software Board determines in good faith, based on such
      matters as it deems relevant, including consultation with outside counsel,
      that engaging in negotiations or discussions or providing information in
      response to such unsolicited Acquisition Proposal is required to satisfy
      the directors' fiduciary duties under the Delaware General Corporation
      Law;

then Sterling Software may furnish information concerning Sterling Software and
its subsidiaries under a customary confidentiality agreement to the person
making the Superior Proposal and participate in negotiations and discussions
regarding the Superior Proposal.

    In response to a Superior Proposal which was not solicited by Sterling
Software and which did not otherwise result from a breach of the provisions of
the Merger Agreement described above, Sterling Software may terminate the Merger
Agreement if the Sterling Software Board determines in good faith, based on such
matters as it deems relevant, including consultation with outside counsel, that
the directors' fiduciary duties under the Delaware General Corporation Law
require termination. Termination under this provision of the Merger Agreement
may only occur after the third business day following Computer Associates'
receipt of written notice from Sterling Software advising that the Sterling
Software Board is prepared to accept the Superior Proposal, and Sterling
Software must pay a fee in the amount of $175 million, plus expenses, to
Computer Associates promptly upon such termination. See "--Termination Fee;
Expenses."

    No provision of the Merger Agreement prohibits the Sterling Software Board
from taking and disclosing to Sterling Software's stockholders a position with
respect to a tender offer made pursuant to Rules 14d-9 and 14e-2 promulgated
under the Exchange Act or from making any disclosure required by applicable law.

    The Merger Agreement provides that:

    - the term "Acquisition Proposal" means any inquiry, proposal or offer from
      any person, other than Computer Associates, Silversmith Acquisition Corp.
      or any of their affiliates, relating to any merger, consolidation,
      recapitalization, liquidation or other direct or indirect business
      combination involving Sterling Software or any of its significant
      subsidiaries, any direct or indirect acquisition or purchase of 15% or
      more (by voting power) of the outstanding capital stock of Sterling
      Software or any of its significant subsidiaries, any tender offer or
      exchange offer that if completed would result in any person (together with
      its affiliates) owning 15% or more (by voting power) of the outstanding
      capital stock of Sterling Software or any of its significant subsidiaries,
      or the acquisition, license, purchase or other disposition of a
      substantial portion of the technology, business or assets of Sterling
      Software or any of its significant subsidiaries outside the ordinary
      course of business or inconsistent with past practice; and

    - the term "Superior Proposal" means any bona fide acquisition proposal
      which is on terms that the Sterling Software Board determines in its good
      faith judgment (after receipt of the advice of a financial advisor of
      nationally recognized reputation) provides for consideration which would
      exceed the value of the consideration provided for in the Offer and the
      Merger, after taking into account all relevant factors, including any
      conditions to such Acquisition Proposal, the timing of

                                       15
<PAGE>
      the closing thereof, the risk of nonconsummation, the ability of the
      person making the Acquisition Proposal to finance the transaction
      contemplated thereby and any required governmental or other consents,
      filings and approvals.

    Sterling Software has agreed to promptly advise Computer Associates of any
request for information relating to an Acquisition Proposal or any inquiry
relating to or which could result in an Acquisition Proposal, including the
material terms and conditions of such request, Acquisition Proposal or inquiry
and the identity of the person making the same. Sterling Software has agreed to
inform Computer Associates on a prompt basis of the status and content of any
discussions regarding any Acquisition Proposal with a third party and as
promptly as possible of any change in the price, structure or form of the
consideration or material terms of and conditions regarding such Acquisition
Proposal.

    COMPLIANCE BY SILVERSMITH ACQUISITION CORP.  Pursuant to the Merger
Agreement, Computer Associates agreed that it will take all action necessary,
including ensuring that Silversmith Acquisition Corp. has sufficient funds and
shares of Computer Associates Common Stock, to cause Silversmith Acquisition
Corp. to perform its obligations under the Merger Agreement and to consummate
the Offer and the Merger on the terms and conditions set forth in the Merger
Agreement.

    EMPLOYEE BENEFITS.  Except as otherwise provided in the Merger Agreement,
Computer Associates has agreed to honor, in accordance with their terms, all of
Sterling Software's benefit plans and all severance and employment agreements
disclosed to Computer Associates and all accrued benefits vested thereunder;
provided that Computer Associates is not prevented from terminating any such
benefit plan or other agreement in accordance with its terms. In addition,
Computer Associates has agreed to provide employees of Sterling Software and its
subsidiaries retained by Computer Associates with employee benefits in the
aggregate no less favorable than those benefits provided to similarly situated
employees of Computer Associates.

    DIRECTORS AND OFFICERS INSURANCE AND INDEMNIFICATION.  The Merger Agreement
provides that, for six years after the Effective Time, Computer Associates and
Sterling Software, as the corporation surviving the Merger, will indemnify and
hold harmless, including advancement of expenses, the current and former
directors and officers of Sterling Software in respect of acts or omissions
occurring on or prior to the Effective Time to the extent provided in Sterling
Software's certificate of incorporation, by-laws and indemnity agreements in
effect on the date of the Merger Agreement, subject to any limitation imposed
from time to time under applicable law. Computer Associates has agreed to
maintain Sterling Software's current directors' and officers' insurance and
indemnification policy to the extent that it provides coverage for events
occurring prior to the Effective Time or provide similar coverage for a period
of not less than two years from the Effective Time for all persons who are
directors and officers of Sterling Software on the date of the Merger Agreement,
provided that Computer Associates will not be obligated to pay an annual premium
for any such coverage in excess of the premium paid by Sterling Software for its
most recent fiscal year.

    STERLING SOFTWARE STOCKHOLDERS MEETING.  If required by applicable law to
effectuate the Merger, the Merger Agreement requires Sterling Software to call a
meeting of its stockholders as soon as reasonably practicable after acceptance
for payment of Shares tendered in the Offer. Under the Merger Agreement, at any
such meeting, Computer Associates and Silversmith Acquisition Corp. have agreed
to make a quorum and to vote all Shares acquired in the Offer or otherwise
beneficially owned by them in favor of adoption of the Merger Agreement. If the
Minimum Tender Condition is satisfied pursuant to the Offer, Silversmith
Acquisition Corp. will hold at least a majority of the outstanding Shares and
will be able to assure that the requisite number of affirmative votes in favor
of approval and adoption of the Merger Agreement will be received, even if no
other stockholder votes in favor thereof. If Silversmith Acquisition Corp.
obtains at least 90% of the outstanding Shares pursuant to the

                                       16
<PAGE>
Offer, it has agreed to effect the Merger without any notice to and without the
authorization of the stockholders of Sterling Software pursuant to Section 253
of the Delaware General Corporation Law.

    ANTITRUST APPROVALS.  Pursuant to the Merger Agreement, each of Computer
Associates and Sterling Software has agreed to:

    - promptly make or cause to be made the filings required of such party or
      any of its subsidiaries under the HSR Act, the Sherman Act, as amended,
      the Clayton Act, as amended, the Federal Trade Commission Act, as amended,
      and any other Federal, state or foreign statutes, rules, regulations,
      orders or decrees that are designed to prohibit, restrict or regulate
      actions having the purpose or effect of monopolization or restraint of
      trade (collectively, "Antitrust Laws") with respect to the transactions
      contemplated by the Merger Agreement and the Tender Agreement (as defined
      below);

    - comply at the earliest practicable date with any request under the HSR Act
      or other Antitrust Laws for additional information, documents, or other
      material received by such party or any of its subsidiaries from any
      governmental entity in respect of such filings or such transactions;

    - cooperate with the other party in connection with any such filing and in
      connection with resolving any investigation or other inquiry of any such
      agency or other governmental entity under any Antitrust Laws with respect
      to any such filing or any such transaction;

    - use all reasonable efforts to take such action as may be required to cause
      the expiration of the notice periods under the HSR Act or other Antitrust
      Laws with respect to such transactions as promptly as possible after the
      execution of the Merger Agreement; and

    - use all reasonable efforts to resolve such objections, if any, as may be
      asserted by any governmental entity with respect to the transactions
      contemplated by the Merger Agreement or the Tender Agreement under any
      Antitrust Laws.

    If any administrative or judicial action or proceeding is instituted or
threatened to be instituted challenging any transaction contemplated by the
Merger Agreement or the Tender Agreement as violative of any Antitrust Law, and,
if by mutual agreement, Computer Associates and Sterling Software decide that
litigation is in their best interests, each has agreed to cooperate and use all
reasonable efforts vigorously to contest and resist any such action or
proceeding and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order, whether temporary, preliminary or
permanent, that is in effect and that prohibits, prevents or restricts
consummation of the Offer, the Merger or any such other transactions.

    The parties' agreements to cooperate in resolving objections or proceedings
raised under any Antitrust Laws with respect to the Offer and the Merger are
subject to the following limitations in the Merger Agreement:

    - neither Computer Associates nor any of its subsidiaries will be required
      to divest any of their respective businesses, product lines or assets;

    - neither Computer Associates nor any of its subsidiaries will be required
      to take or agree to take any other action or agree to any limitation that
      could reasonably be expected to have an adverse effect on the business,
      assets, condition, results of operations or prospects of Computer
      Associates and its subsidiaries taken as a whole or Computer Associates
      combined with Sterling Software after the Effective Time;

    - neither Sterling Software nor its subsidiaries shall be required to divest
      any of their respective businesses, product lines or assets, or to take or
      agree to take any other action or agree to any

                                       17
<PAGE>
      limitation that could reasonably be expected to have a material adverse
      effect with respect to Sterling Software;

    - no party to the Merger Agreement will be required to agree to the
      imposition of or to comply with, any condition, obligation or restriction
      on Computer Associates or any of its subsidiaries or on Sterling Software
      (as surviving corporation of the Merger) or certain of its subsidiaries;
      and

    - neither Computer Associates nor Silversmith Acquisition Corp. will be
      required to waive any of the conditions to the Offer or the Merger
      described under "--Conditions of the Offer" or "--Conditions to the
      Completion of the Merger."

    FURTHER ASSURANCES.  Each of Computer Associates and Sterling Software has
agreed, pursuant to the Merger Agreement, to use all reasonable efforts to take,
or cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Offer, the Merger, and the other transactions contemplated by

      adopted the Merger and the Merger Agreement;

    - Silversmith Acquisition Corp. having accepted for exchange and exchanged
      all shares of Sterling Software Common Stock tendered pursuant to the

      such condition;

    - no judgment, order, decree, statute, law, ordinance, rule or regulation
      entered, enacted, promulgated, enforced or issued by any court or other

       that Computer Associates shall not be permitted to terminate the Merger
       Agreement if the Offer is terminated or expires without Shares being
       accepted for exchange in violation of the Merger Agreement;

    (3) by Computer Associates or Sterling Software if the Offer shall not have
       been consummated on or before September 30, 2000, unless the failure to

       the Merger Agreement by the party seeking to terminate;

                                       18
<PAGE>
    (4) by Computer Associates or Sterling Software if the Merger shall not have
       been consummated as a result of any condition described above under
       "--Conditions to the Completion of the Merger" being incapable of being
       satisfied;

    (5) if any statute, rule, regulation, injunction or decree having the

result of the occurrence of any of the events set forth below (each, a "Trigger
Event"):

    (1) Sterling Software shall have received an Acquisition Proposal, and at
       any time prior to, or within one year after the termination of the Merger
       Agreement, unless the Merger Agreement is terminated pursuant to

       Events," Sterling Software shall have entered into, or shall have

       material respect any of its representations, warranties, covenants or
       other agreements contained in the Merger Agreement, which breach or

       forth in the third or fourth "bullets" of Section (5) of "--Conditions of
       the Offer", and (B) is incapable of being or has not been cured by
       Sterling Software within 10 calendar days after giving written notice to

       withdrawn or materially modified or amended in a manner adverse to
       Computer Associates or Silversmith Acquisition Corp. its approval or
       recommendation of the Offer, the Merger or the Merger Agreement or its
       approval of the entry by Silversmith Acquisition Corp. into the Tender
       Agreement, or shall have failed to make such favorable recommendation, or
       (B) the Sterling Software Board, or any committee thereof, shall have
       recommended to the stockholders of Sterling Software any Acquisition
       Proposal or shall have resolved to, or publicly announced an intention

Associates for, all reasonably documented out-of-pocket fees payable and
expenses incurred by Computer Associates, including the fees and expenses of its
counsel, in connection with the Merger Agreement, up to a maximum of
$10 million, which amount shall include the fees and expenses allocated to or
paid by Sterling Software as described in the immediately preceding paragraph.

    TENDER AGREEMENT.  As required by Computer Associates as a condition to its
entering into the Merger Agreement, on February 14, 2000, Silversmith
Acquisition Corp. entered into an agreement (the "Tender Agreement") with
certain stockholders of Sterling Software, including its directors and certain
members of senior management of Sterling Software (each, a "Stockholder"), with
respect to an aggregate of 2,490,550 Shares owned by such Stockholders. The
following is a summary of certain provisions of the Tender Agreement. The
summary is qualified in its entirety by reference to the full text of the Tender
Agreement, a copy of which is filed herewith as Exhibit (e)(39) and is
incorporated herein by reference.

    Pursuant to the Tender Agreement, each Stockholder has agreed to tender for
exchange in the Offer all Shares then owned or thereafter acquired by such
Stockholder.

    Pursuant to the Tender Agreement, each Stockholder has agreed that during
the term of the Tender Agreement, at any meeting of Sterling Software's
stockholders, such Stockholder will vote all of such Stockholder's Shares
(i) in favor of the adoption of the Merger Agreement and the approval of the
Merger and (ii) against any action or agreement that would result in a breach of
any covenant, representation or warranty or the failure to fulfill any other
obligation or agreement of Sterling Software under the Merger Agreement. In
addition, each Stockholder has appointed Silversmith Acquisition Corp. or any
nominee of Silversmith Acquisition Corp. as proxy to vote its Shares in
accordance with the foregoing. Each Stockholder has also agreed not to transfer
its Shares without the prior written consent of Silversmith Acquisition Corp.

    Under the terms of the Tender Agreement, each Stockholder has agreed that
such Stockholder will not directly or indirectly (i) subject to the fiduciary
duty under applicable law of such Stockholder as a director of Sterling Software
(if such Stockholder is such a director) as further provided in the Merger
Agreement, solicit, initiate or encourage (or authorize any person to solicit,
initiate or encourage) any inquiry, proposal or offer from any person to acquire
the business, property or capital stock of Sterling Software or any direct or
indirect subsidiary thereof, or any acquisition of a substantial equity interest
in, or a substantial amount of the assets of, Sterling Software or any direct or
indirect subsidiary thereof, whether by merger, purchase of assets, tender offer
or other transaction or (ii) subject to the fiduciary duty under applicable law
of such Stockholder as a director of Sterling Software (if such Stockholder is
such a director) as further provided in the Merger Agreement, participate in any
discussions or negotiations regarding, or furnish to any other person any
information with respect to, or otherwise cooperate in any way with, or
participate in, facilitate or encourage any effort or attempt by any other
person to do or seek any of the foregoing. Each Stockholder has agreed to
promptly advise Silversmith Acquisition Corp. of the terms of any communications
it may receive in the capacity as a stockholder relating to any of the
foregoing.

                                       20
<PAGE>
    INDEMNIFICATION AND INSURANCE.  The Merger Agreement provides that Computer
Associates and the Surviving Corporation will, for a period of six years after
the Effective Time, indemnify and hold harmless the current and former directors
and officers of Sterling Software in connection with any acts or omissions
occurring on or prior to the Effective Time to the extent provided in Sterling
Software's certificate of incorporation, by-laws or indemnification agreements
in effect on the date of the Merger Agreement, provided that such
indemnification shall be subject to any limitation imposed from time to time
under applicable law. In addition, Computer Associates will maintain, for a
period of two years after the Effective Time, Sterling Software's current
directors' and officers' liability insurance and indemnification policy to the
extent it provides coverage with respect to matters occurring prior to the
Effective Time for all persons who are directors or officers of Sterling
Software on the date of the Merger Agreement, so long as the annual premium
therefor will not exceed the annual premium paid by Sterling Software in its
last fiscal year, provided that if such insurance cannot be so maintained,
expires or is terminated or canceled during such two-year period, Computer
Associates will use reasonable efforts to cause to be obtained as much of such
insurance as can be obtained for an annual premium not in excess of the annual
premium paid by Sterling Software in its last fiscal year, on terms and
conditions substantially similar to Sterling Software's existing insurance.

ITEM 4. THE SOLICITATION OR RECOMMENDATION.

        (a) RECOMMENDATION OF STERLING SOFTWARE BOARD.

    At a meeting held on February 13, 2000, the Sterling Software Board
unanimously approved the Merger Agreement and the transactions contemplated
thereby, including the Offer and the Merger, and determined that the
transactions contemplated by the Merger Agreement, including the Offer and the
Merger, are advisable, fair to and in the best interests of Sterling Software's
stockholders.

    The Sterling Software Board recommends that Sterling Software's stockholders
accept the Offer and tender their Shares pursuant to the Offer.

    A letter to Sterling Software's stockholders communicating the Sterling
Software Board's recommendation and a press release announcing the execution of
the Merger Agreement are filed herewith as Exhibits (a)(3) and (a)(4),
respectively, and are incorporated herein by reference.

        (b)BACKGROUND; REASONS FOR THE STERLING SOFTWARE BOARD'S RECOMMENDATION;
           OPINION OF GOLDMAN, SACHS & CO.

    BACKGROUND

    Beginning in November, 1999, senior management of Sterling Software began to
explore and analyze Sterling Software's strategic alternatives in order to
maximize stockholder value. Such exploration and analysis was in keeping with
the historical practices of Sterling Software's senior management team, which
typically undertook a thorough review of the condition and future direction of
Sterling Software and its businesses in the first quarter of each fiscal year.
Among other things, Sterling Software's senior management explored and analyzed
the following: (i) remaining as a stand-alone company and operating in
accordance with the status quo, (ii) remaining as a stand-alone company, but
varying certain aspects of Sterling Software's basic business model, (iii) a
break-up, spin-off or split-up of Sterling Software into multiple companies, and
(iv) a possible sale of all or part of Sterling Software. After evaluating each
of these alternatives in detail, management concluded that a combination of
Sterling Software with another large company in the software or information
technology industries was likely to result in the greatest stockholder value and
the least amount of execution risk.

                                       21
<PAGE>
    As a result of this conclusion, Sterling Software engaged financial
advisors, Goldman, Sachs & Co. and Broadview International, LLC ("Broadview"),
to perform independent analyses of the alternatives reviewed by management and
to represent Sterling Software in the event a transaction or series of
transactions were to occur. Goldman, Sachs & Co. and Broadview completed these
analyses, which included extensive discussions with Sterling Software's
management, and both firms concurred with management's conclusion regarding the
best course of action to maximize stockholder value.

    Sterling Software's management, with the assistance of its financial
advisors, then identified a number of third parties in the computer software and
information technology industries who might have an interest in engaging in a
business combination transaction with Sterling Software. However, on
January 14, 2000, before any contacts had been made with any third party,
Mr. Sanjay Kumar, President and Chief Operating Officer of Computer Associates,
contacted Mr. Sam Wyly, Chairman of the Sterling Software Board, to discuss the
possibility of a business combination between Computer Associates and Sterling
Software. On January 18, 2000, Messrs. Kumar and Wyly met in Dallas to discuss
their respective businesses and various potential strategic business
arrangements that might benefit both Computer Associates and Sterling Software.
They also discussed the potential valuation of Sterling Software.

    Commencing in late January, 2000, representatives of Goldman, Sachs & Co.
and Broadview contacted a number of third parties in an effort to ascertain on a
preliminary basis their level of interest in engaging in a business combination
transaction with Sterling Software. Other than Computer Associates, none of
Sterling Software, Goldman, Sachs & Co. or Broadview engaged in any substantive
discussions regarding a business combination with any third parties because
those contacts did not result in any specific proposal or any indication of a
serious level of interest. The third parties contacted generally expressed
either modest interest, indifference or no interest in a business combination
transaction with Sterling Software.

    On January 23, 2000, Mr. Kumar, Mr. Ira Zar, Senior Vice President--Finance
and Chief Financial and Accounting Officer of Computer Associates, Mr. Charles
McWade, Senior Vice President--Business Development of Computer Associates, and
representatives of Computer Associates' financial advisor, Morgan Stanley & Co.
Incorporated, met with Mr. Wyly, Mr. Sterling Williams, President and Chief
Executive Officer of Sterling Software, and other members of senior management
of Sterling Software. During this meeting the Computer Associates
representatives were provided with an overview of Sterling Software's businesses
and operations and were provided with certain non-public financial information
of Sterling Software, including certain financial forecasts. At the meeting,
Mr. Kumar indicated that Computer Associates was still reviewing possible
transaction structures for a business combination with Sterling Software.

    On January 26, 2000, Messrs. Kumar and Williams further discussed potential
transaction structures, as well as certain timing considerations. On both
January 29 and January 30, 2000, Messrs. Kumar and Williams briefly discussed
certain valuation issues.

    On February 4, 2000, Mr. Williams and Mr. Logan Wray, Sterling Software's
Chief Financial Officer, met with Mr. Kumar to discuss financial assumptions and
issues regarding possible benefits from a combination of the two companies.

    On February 6, 2000, during a telephone call with Mr. Williams, Mr. Kumar
indicated that Computer Associates was interested in pursuing a transaction,
subject to board approval, completion of due diligence and the negotiation of
satisfactory definitive agreements, valued at between $38.25 and $39.25 for each
share of Sterling Software Common Stock (with the possibility of an increase
based on Computer Associates' further review of Sterling Software's business
intelligence business). Mr. Kumar suggested that the transaction might be
structured as an exchange offer followed by a merger and be treated as a
purchase for accounting and financial reporting purposes. Mr. Williams informed
Mr. Kumar that he would consider and review the proposal with other members of
senior management

                                       22
<PAGE>
of Sterling Software and its legal and financial advisors. Messrs. Kumar and
Williams then discussed certain timing and logistics issues.

    On February 6, 2000, Mr. Williams held a meeting with other senior members
of management of Sterling Software, and a telephonic meeting with
representatives of Skadden, Arps, Slate, Meagher & Flom LLP, Sterling Software's
legal advisor ("Skadden Arps"), and Goldman, Sachs & Co., to update them on his
discussions with Mr. Kumar. Mr. Williams separately briefed representatives of
Broadview.

    On February 6, 2000, Messrs. Kumar and Williams again spoke by telephone to
discuss certain terms of the proposed transaction. Messrs. Williams and Kumar
discussed the value of the consideration being proposed, the possibility of a
"collar" around the price of the Computer Associates Common Stock and the nature
of the contractual conditions to the ultimate completion of a potential
transaction.

    On February 7, 2000, Messrs. Kumar and Williams spoke several times by
telephone to further discuss the proposed transaction, including the collar
mechanism.

    On February 8, 2000, Messrs. Kumar and Williams further discussed certain
terms of the proposed transaction. They discussed possible terms of a proposed
strategic business combination that would justify continuing their discussions,
conducting mutual due diligence and negotiating definitive documents, all
subject to satisfactory completion of due diligence and the approval of their
respective Boards of Directors, including consideration consisting of $39.50 per
share of Computer Associates Common Stock, subject to a 10% collar; a structure
involving a first-step exchange offer followed by a second-step merger; and
limited conditions in the definitive merger agreement. They also discussed the
treatment of Sterling Software's outstanding stock options in the proposed
transaction.

    On February 8, 2000, the Sterling Software Board met by conference telephone
with its financial and legal advisors. Mr. Williams reported on the status of
negotiations with Computer Associates and the terms of Computer Associates'
proposal generally and reviewed the process to be followed in connection with
evaluating the proposal. Goldman, Sachs & Co. provided an overview of its
preliminary contacts with other potential strategic buyers and the likelihood of
transactions between Sterling Software and those third parties. At the meeting,
Skadden Arps advised the Sterling Software Board regarding its fiduciary duties
with respect to any potential business combination transaction involving
Computer Associates.

    On February 9, 2000, Computer Associates and Sterling Software entered into
confidentiality agreements covering the exchange of nonpublic information
between the companies for the purpose of evaluating a potential strategic
business combination.

    From February 9 to February 13, 2000, representatives of Computer Associates
and Sterling Software and their respective legal and financial advisors
conducted due diligence examinations of each other's businesses.

    From February 10 to February 13, 2000, Sterling Software and its legal and
financial advisors negotiated the terms of the merger agreement and related
documents with Computer Associates and its legal and financial advisors.

    The Sterling Software Board held a special meeting on February 13, 2000 to
discuss the proposed transaction with Computer Associates and the terms of the
Merger Agreement. Mr. Williams updated the Sterling Software Board on the
negotiations with Computer Associates. Mr. Williams, with assistance from
representatives of Goldman, Sachs & Co. and Broadview, reviewed the strategic
business rationale for the transaction and the prospects for Sterling Software
on a stand-alone basis. In addition, Goldman, Sachs & Co. made a detailed
financial presentation (which is summarized below) and orally delivered its
opinion, which it subsequently confirmed in writing, that as of that date and
subject to the limitations and considerations described therein, the
consideration to be received by Sterling Software's stockholders pursuant to the
Merger Agreement was fair from a financial point of

                                       23
<PAGE>
view to such stockholders. In addition, representatives of Skadden Arps
summarized the terms and conditions of the Merger Agreement, the Tender
Agreement, certain amendments to Sterling Software's executive severance
agreements and related legal documents, and discussed the directors' fiduciary
duties under Delaware law. Among other things, Skadden Arps informed the
Sterling Software Board that the terms of the Merger Agreement did not contain a
condition based on a material adverse change in Sterling Software's business
following the announcement of the transaction or a provision requiring that
Sterling Software enter into a stock option agreement with Computer Associates,
both of which had been initially requested by Computer Associates, and explained
the impact of the deletion thereof.

    During the course of the Sterling Software Board meeting, Skadden Arps,
Broadview and Goldman, Sachs & Co. met separately with the independent directors
of Sterling Software to review the transaction, the amendments to the severance
agreements and other agreements. Thereafter, the independent directors advised
the full Sterling Software Board that such independent directors were
unanimously in favor of the transaction.

    After discussion and consideration of the factors and reasons described
below under "--Reasons for the Sterling Software Board's Recommendation," the
Sterling Software Board unanimously determined that the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger, are
advisable, fair to and in the best interests of, Sterling Software's
stockholders, unanimously approved the Merger Agreement and the transactions
contemplated thereby, including the Offer and the Merger, and unanimously
recommended that Sterling Software's stockholders accept the Offer and tender
their shares of Sterling Software Common Stock pursuant to the Offer.

    Following the meeting of the Sterling Software Board, on February 14, 2000,
Sterling Software and Computer Associates executed the Merger Agreement, and
Silversmith Acquisition Corp. and certain stockholders of Sterling Software,
including its directors and certain members of senior management, executed the
Tender Agreement. A joint press release announcing the proposed Offer and Merger
was issued on February 14, 2000.

    On February 22, 2000, Computer Associates commenced the Offer.

    REASONS FOR THE STERLING SOFTWARE BOARD'S RECOMMENDATION

    In approving the Offer, the Merger, the Merger Agreement and the
transactions contemplated thereby and recommending that all holders of Shares
accept the Offer and tender their Shares pursuant to the Offer, the Sterling
Software Board considered a number of factors, including:

        1.  the financial condition, results of operations, cash flows,
    earnings, assets and prospects of Sterling Software, if it remains an
    independent company;

        2.  the presentations of Goldman, Sachs & Co. and Broadview, and the
    opinion of Goldman, Sachs & Co. to the effect that, subject to the matters
    set out in such opinion, the consideration to be paid pursuant to the Merger
    Agreement is fair from a financial point of view to Sterling Software's
    stockholders (see "--Opinion of Goldman, Sachs & Co." below and Schedule III
    hereto);

        3.  the fact that the market value of the shares of Computer Associates
    Common Stock, based on the Exchange Ratio and the closing price of such
    shares on the NYSE on February 11, 2000, to be exchanged for each Share
    pursuant to the Offer and the Merger represents a premium of approximately
    14.1% over the closing price of the Shares on the NYSE on February 11, 2000,
    and a premium of approximately 34.8% over the average of the closing prices
    of the Shares on the NYSE for the last 30 days of trading prior to
    February 11, 2000;

        4.  the financial and other terms of the Offer, the Merger and the
    Merger Agreement, including the benefits of the transaction being structured
    as a first-step exchange offer and

                                       24
<PAGE>
    second-step merger, which may provide Sterling Software's stockholders with
    an opportunity to receive shares of Computer Associates Common Stock on an
    accelerated basis;

        5.  the fact that the provisions of the Merger Agreement are designed to
    provide that the total value (based on the average Computer Associates
    trading price) of the Computer Associates Common Stock, or Computer
    Associates Common Stock and cash, to be exchanged for each share of Sterling
    Software Common Stock in the Offer and Merger will have a value of at least
    $35.55, which represents a premium of approximately 3.2% over the closing
    price of the shares of Sterling Software Common Stock on the NYSE on
    February 11, 2000, and a premium of approximately 21.9% over the average
    closing prices of the Shares on the NYSE for the last 30 days of trading
    prior to February 11, 2000;

        6.  the fact that the provisions of the Merger Agreement are designed to
    provide that the value (based on the average Computer Associates trading
    price) of the shares of Computer Associates Common Stock to be received in
    the Offer could increase to as much as $43.45 in the event that the price of
    Computer Associates Common Stock increases prior to the consummation of the
    Offer, which represents a premium of approximately 26.2% over the closing
    price of the shares of Sterling Software Common Stock on the NYSE on
    February 11, 2000, and a premium of approximately 49.0% over the average
    closing prices of the Shares on the NYSE for the last 30 days of trading
    prior to February 11, 2000;

        7.  the recent and historical stock price performance of the shares of
    Sterling Software Common Stock and Computer Associates Common Stock;

        8.  the belief by Sterling Software's management that the shares of
    Sterling Software Common Stock have historically been undervalued due in
    part to the multi-segment nature of Sterling Software's businesses, making
    it more expensive, and thus exceedingly difficult, for Sterling Software to
    continue its strategy of achieving growth through acquisitions of other
    companies and businesses, and thereby making it more difficult for Sterling
    Software to achieve growth levels consistent with those historically
    achieved by Sterling Software;

        9.  the potential strategic alternatives available to Sterling Software
    and the viability and risks associated with each alternative, including the
    prospects for Sterling Software on a stand-alone basis and the risks
    associated with achieving and executing upon Sterling Software's business
    plan, both short-term and long-term;

        10.  the belief of Sterling Software's management that, based on its
    review of Sterling Software's strategic alternatives and on the feedback
    from recent preliminary contacts with a number of third parties in the
    computer software and information technology industries to ascertain their
    level of interest in engaging in a business combination transaction with
    Sterling Software, it is unlikely that any party would propose an
    alternative transaction that would be more favorable to Sterling Software
    and its stockholders than the Offer and the Merger;

        11.  the fact that the Offer and the Merger will present the opportunity
    for the holders of shares of Sterling Software Common Stock to participate
    in a significantly larger and more diversified company and, as stockholders
    of the combined company, to have greater liquidity in their shares and to
    benefit from any future growth of the combined company;

        12.  the Sterling Software Board's expectation that the addition of
    Sterling Software's operations to Computer Associates would likely increase
    the overall value and profitability of Computer Associates, tending to
    produce greater stockholder value for Sterling Software's stockholders;

        13.  the presentations by, and discussions of the terms of the Merger
    Agreement with, Sterling Software's senior management, Skadden Arps,
    Goldman, Sachs & Co. and Broadview;

                                       25
<PAGE>
        14.  the terms and conditions of the Merger Agreement and the conditions
    of the Offer, including the absence of a condition based on a material
    adverse change in Sterling Software's business following the announcement of
    the transaction, and the nature of the arm's-length negotiation of the
    Merger Agreement;

        15.  the likelihood that the Offer and the Merger would be consummated,
    including the limited nature of the conditions to the Offer and the
    experience, reputation and financial condition of Computer Associates;

        16.  the consents and approvals required to consummate the Offer and the
    Merger, including regulatory clearance under the HSR Act and foreign
    antitrust laws, and the favorable prospects for receiving such consents and
    approvals;

        17.  the fact that while the Merger Agreement prohibits Sterling
    Software from soliciting proposals concerning an acquisition of Sterling
    Software, the Sterling Software Board, in the exercise of its fiduciary
    duties, would be able to provide information to, and engage in negotiations
    with, a third party that makes an unsolicited superior acquisition proposal,
    and that the Sterling Software Board would be able to terminate the Merger
    Agreement and accept a superior acquisition proposal if it determines that
    its fiduciary duties so require, upon payment to Computer Associates of a
    termination fee of $175 million, plus reimbursement of Computer Associates'
    expenses up to a maximum of $10 million;

        18.  the fact that the Offer and the Merger are structured in a manner
    so that in certain circumstances (the existence of which will not be known
    prior to the consummation of the Offer and the Merger), they should qualify
    as a reorganization for federal income tax purposes, in which case Sterling
    Software's stockholders would generally not recognize gain or loss except
    for any gain recognized in connection with any cash received (i) for
    fractional shares of Computer Associates Common Stock or (ii) if Computer
    Associates elects the Cash Option (although the circumstances may develop
    such that the Offer, the Merger, or both may be taxable transactions to
    Sterling Software's stockholders, as described under the heading "Material
    Federal Income Tax Consequences" in the Exchange Offer);

        19.  the potential effect of the public announcement of the Offer and
    the Merger on Sterling Software's ability to attract and retain key
    management, sales, marketing and technical personnel;

        20.  the opportunity of the combined company to reduce costs through
    economies of scale that would not have been readily achievable by Sterling
    Software independently, and the elimination of redundant operations and
    duplicate administrative functions;

        21.  the opportunity of the combined company to further enhance research
    and development efforts, including potentially more rapid development of
    products as a result of shared knowledge between software development teams;

        22.  the strengths and weaknesses of Computer Associates' businesses and
    the key attributes of the combined company in terms of, among other things,
    products, sales, customers, management and competitive position;

        23.  the fact that the computer software industry is extremely
    competitive and is characterized by rapid change and uncertainty due to new
    and emerging technologies and low barriers to entry and the fact that
    Sterling Software derives a significant portion of its revenue from mature
    software products;

        24.  the nature of the enterprise software segment of the broader
    software industry and the fact that greater size and resources are
    increasingly required for companies to successfully compete in this segment;
    and

                                       26
<PAGE>
        25.  the increasing competition in Sterling Software's markets from both
    existing and potential competitors, some of which have greater assets and
    resources than Sterling Software, which has occurred as a result of, among
    other reasons, the consolidation taking place in the computer software
    industry in general and in the enterprise software segment in particular.

    The Sterling Software Board did not assign relative weights to the foregoing
factors or determine that any factor was of particular importance. Rather, the
Sterling Software Board viewed its position and recommendations as being based
on the totality of the information presented to and considered by the Sterling
Software Board. In addition, individual members of the Sterling Software Board
may have given different weights to different factors.

    The foregoing discussion of the information and factors considered by the
Sterling Software Board is not intended to be exhaustive but is believed to
include all material factors considered by the Sterling Software Board. In view
of the wide variety of factors, both positive and negative, considered by the
Sterling Software Board, the Sterling Software Board did not find it practical
to, and did not, quantify or otherwise assign relative weights to the specific
factors considered.

    OPINION OF GOLDMAN, SACHS & CO.

    Sterling Software retained Goldman, Sachs & Co. pursuant to a letter
agreement, dated January 10, 2000 (the "Goldman, Sachs & Co. Letter Agreement"),
to act as financial advisor in connection with the possible sale of all or a
portion of Sterling Software . Goldman, Sachs & Co. is a nationally recognized
investment banking firm and was selected by Sterling Software based on the
firm's reputation and experience in investment banking in general and its
recognized expertise in the valuation of businesses as well as its prior
investment banking relationships with Sterling Software.

    On February 13, 2000, at the meeting of the Sterling Software Board,
Goldman, Sachs & Co. delivered to the Sterling Software Board its oral opinion
(which was subsequently confirmed in a written opinion, dated February 14, 2000)
that, as of such date and based on and subject to the matters set forth therein,
the consideration to be received pursuant to the Merger Agreement was fair, from
a financial point of view, to the holders of Sterling Software Common Stock.

    You should consider the following when reading the discussion of the opinion
of Goldman, Sachs & Co. herein:

    - we urge you to read carefully the entire opinion of Goldman, Sachs & Co.
      which is attached as Schedule III to the Schedule 14D-9 and is
      incorporated herein by reference;

    - Goldman, Sachs & Co.'s advisory services and opinion were provided to the
      Sterling Software Board for its information in its consideration of the
      Merger and was directed only to the fairness, from a financial point of
      view, of the consideration to be received in the Offer and the Merger by
      the holders of Sterling Software Common Stock; and

    - Goldman, Sachs & Co.'s opinion does not constitute a recommendation as to
      whether or not any holder of Sterling Software Common Stock should tender
      such Sterling Software Common Stock in connection with the Offer or as to
      how any holder of Sterling Software Common Stock should vote with respect
      to the Merger.

    Although Goldman, Sachs & Co. evaluated the fairness, from a financial point
of view, of the consideration to be received by the holders of Sterling Software
Common Stock pursuant to the Merger Agreement, the consideration itself was
determined by Sterling Software and Computer Associates through arm's-length
negotiations. Sterling Software did not provide specific instructions to, or
place any limitations on, Goldman, Sachs & Co. with respect to the procedures to
be followed or factors to be considered by Goldman, Sachs & Co. in performing
its analyses or providing its opinion.

                                       27
<PAGE>
    In connection with its opinion, Goldman, Sachs & Co. reviewed, among other
things, the following:

    - the Merger Agreement;

    - the Annual Reports to Stockholders and Annual Reports on Form 10-K of
      Sterling Software and Computer Associates for the five years ended
      September 30, 1999 and March 31, 1999, respectively;

    - certain interim reports to stockholders and Quarterly Reports on
      Form 10-Q of Sterling Software and Computer Associates;

    - certain other communications from Sterling Software and Computer
      Associates to their respective stockholders; and

    - certain internal financial analyses and certain base and risk adjusted
      case forecasts for Sterling Software prepared by its management (the
      "Forecasts"), including certain cost savings and operating synergies
      projected by the management of Sterling Software to result from the
      transactions contemplated by the Merger Agreement.

    Goldman, Sachs & Co. also held discussions with members of the senior
management of Sterling Software and Computer Associates regarding the strategic
rationale for, and the potential benefits of, the transactions contemplated by
the Merger Agreement and the past and current business operations, financial
condition and future prospects of their respective companies. In addition,
Goldman, Sachs & Co.:

    - reviewed the reported price and trading activity for the Sterling Software
      Common Stock and Computer Associates Common Stock;

    - compared certain financial and stock market information for Sterling
      Software and Computer Associates with similar information for certain
      other companies the securities of which are publicly traded;

    - reviewed the financial terms of certain recent business combinations in
      the software industry specifically and in other industries generally; and

    - performed such other studies and analyses as it considered appropriate.

    Goldman, Sachs & Co. relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed such accuracy and
completeness for purposes of rendering its opinion. In addition, Goldman,
Sachs & Co. did not make any independent evaluation or appraisal of the assets
and liabilities of Sterling Software or Computer Associates or any of their
respective subsidiaries, and Goldman, Sachs & Co. was not furnished with any
such evaluation or appraisal. With respect to the financial forecasts for
Sterling Software, Goldman, Sachs & Co. assumed, with the consent of Sterling
Software, that the Forecasts have been reasonably prepared on a basis reflecting
the best currently available estimates and judgments of Sterling Software's
management. Additionally, since Computer Associates declined to make available
to Goldman, Sachs & Co. its projections of expected future performance, Goldman,
Sachs & Co.'s review of Computer Associates' expected future performance was
limited to discussions with members of Computer Associates' senior management
regarding research analyst estimates of future financial performance of Computer
Associates.

    Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. Goldman,
Sachs & Co. is familiar with Sterling Software, having provided certain
investment banking services to Sterling Software from time to time, including
having acted as its financial adviser in connection with, and having
participated in certain of the negotiations leading to, the Merger Agreement.

                                       28
<PAGE>
    Goldman, Sachs & Co. provides a full range of financial advisory and
securities services and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of Sterling Software or Computer Associates for its own account or
for the accounts of customers. As of February 14, 2000, Goldman, Sachs & Co.
accumulated a long position of 9,100 shares of Sterling Software Common Stock
against which Goldman, Sachs & Co. is short 1,700 shares of Sterling Software
Common Stock, a long position of 116,375 shares of Computer Associates Common
Stock against which Goldman, Sachs & Co. was short 182,218 shares of Computer
Associates Common Stock, a short position of $3,000,000 par value of 6.50% bonds
of Computer Associates due April of 2008, and a short position of options to
purchase 10,000 shares of Computer Associates Common Stock. In addition,
Goldman, Sachs & Co. may provide investment banking services to Computer
Associates and its subsidiaries in the future.

    (5) ANALYSIS OF SELECTED SOFTWARE TRANSACTIONS.  Goldman, Sachs & Co.
reviewed the financial terms, to the extent publicly available, of 56 pending or
completed mergers and acquisitions transactions since May 1994 in the software
industry (the "Selected Transactions"). Goldman, Sachs & Co. based this analysis
on publicly available information for each of the Selected Transactions.

    Goldman, Sachs & Co. calculated:

    - the consideration given with respect to each Selected Transaction as a
      multiple of latest twelve month ("LTM") sales immediately prior to the
      announcement of the Selected Transaction;

                                       32
<PAGE>
    - the consideration given with respect to each Selected Transaction as a
      multiple of LTM earnings before interest, income taxes, depreciation and
      amortization ("EBITDA") immediately prior to the announcement of the
      Selected Transaction;

    - the consideration given with respect to each Selected Transaction as a
      multiple of LTM earnings before interest and income taxes ("EBIT")
      immediately prior to the announcement of the Selected Transaction; and

    - the consideration given with respect to each Selected Transaction as a
      multiple of LTM net income immediately prior to the announcement of the
      Selected Transaction.

    The ranges, medians and means of the premiums and the multiples of the
Selected Transactions are set forth in the following table:

    (6) DISCOUNTED CASH FLOW ANALYSIS.  Goldman, Sachs & Co. estimated the
present value of the equity value per share of Sterling Software based on
Sterling Software's management base estimates and Sterling Software's risk
adjusted management estimates. The equity values per share of Sterling Software
Common Stock were calculated based on:

    - Sterling Software management's base estimates and risk adjusted estimates;

    - variations in EBIT margins from -4% to 4%;

    - variations in sales growth rate from -10% to 10%;

    - exit years of 2002 and 2003; and

    - projected EBITDA exit multiples from 8.0x to 10.0x.

    Based on these parameters, Goldman, Sachs & Co. calculated the equity value
per share of Sterling Software as shown in the following table:

</TABLE>

    (7) PRESENT VALUE OF FUTURE STOCK PRICE ANALYSIS.  Goldman, Sachs & Co.
performed an analysis of the present value of potential future prices for
Sterling Software Common Stock using Sterling Software management's base and
risk adjusted estimates. Goldman, Sachs & Co. calculated various future stock
prices as of the beginning of the fiscal years 2002 and 2003, based on one year
forward price/earnings multiples ranging from 12 to 20, and calculated a present
value of such future stock prices using discount rates of from 15% to 25%. This
analysis produced present values of Sterling Software's future common stock
price of from $32 to $78, based on management's base case, and of from $25 to
$52, based on management's risk adjusted case.

    (8) LEVERAGED BUYOUT ANALYSIS. Based on Sterling Software's risk adjusted
management estimates, Goldman, Sachs & Co. performed a leveraged buyout analysis
of Sterling Software assuming a purchase price per share of Sterling Software
Common Stock of $39.30 and total funds required of $3,758.2 million from the
following sources: (i) excess cash on hand of $288 million, (ii) bank debt of
$1,006.2 million, (iii) senior subordinated debt of $375 million and
(iv) equity of $2,089 million.

                                       33
<PAGE>
    On these assumptions, and based on a forward P/E multiple of 16x and
treating fiscal year 2001 as year 1, Goldman, Sachs & Co. calculated:

    - the internal rate of return to equity investors at a purchase price of
      $39.30 per share of Sterling Software Common Stock; and

    - the purchase price per share of Sterling Software Common Stock required to
      yield an internal rate of return of 30% to equity investors to be as shown
      in the following table:

    (9) BREAKUP SEGMENT VALUATION ANALYSIS. Goldman, Sachs & Co. calculated the
implied breakup segment valuations for each of the Sterling Software business
segments by assuming that (i) any gains with respect to the application
development, the business intelligence and the federal systems segments will be
subject to a 35% tax, (ii) the systems management segment will remain in place
and, accordingly, that no taxes will have to be paid as a result of any gain on
that segment and (iii) Sterling Software's cash balance is distributed among its
business segments in proportion to estimated 2000 revenues. The following table
presents (i) assumed multiples for the business segments, based in the case of
the application development segment on the purchase price paid by Sterling
Software for the businesses comprising the segment and in the case of the other
segments on multiples for publicly traded comparable companies, (ii) the low and
high implied breakup segment valuations for each of the Sterling Software
business segments and (iii) the aggregate implied value of Sterling Software's
businesses calculated as the sum of the implied segment valuations of the
Sterling Software business segments along with the corresponding implied per
share value of Sterling Software Common Stock:

(11)  PRO FORMA COMBINED EARNINGS ANALYSIS. Goldman, Sachs & Co. analyzed
certain pro forma effects of the Merger. Based on such analysis, Goldman,
Sachs & Co. calculated the resulting dilution/ accretion to the combined
company's book earnings per share estimates and cash earnings per share
estimates for the fiscal years ending 2001 and 2002, taking into account the
provisions of the Merger Agreement relating to adjustment of the Exchange Ratio,
both before and after taking into account synergies of the Merger as estimated
by Sterling Software's management. Goldman, Sachs & Co. noted that, before
taking into account synergies of the Merger and assuming a range of stock prices
per share of Computer Associates Common Stock of $41.85 to $97.65, the Merger
would be:

    - between 9.8% and 13.7% dilutive to the combined company's book earnings
      per share for fiscal year 2001;

    - between 7.3% and 11.1% dilutive to the combined company's book earnings
      per share for fiscal year 2002;

    - between 1.5% dilutive and 4.5% accretive to the combined company's cash
      earnings per share for fiscal year 2001; and

    - between 0.3% dilutive to 5.8% accretive to the combined company's cash
      earnings per share for fiscal year 2002.

    Goldman, Sachs & Co. also noted that, after taking into account synergies of
the Merger as estimated by Sterling Software's management and assuming a range
of stock prices per share of Computer Associates Common Stock of $41.85 to
$97.65, the Merger would be:

    - between 5.4% and 9.4% dilutive to the combined company's book earnings per
      share for fiscal year 2001;

    - between 2.1% and 6.2%% dilutive to the combined company's book earnings
      per share for fiscal year 2002;

    - between 2.0% and 8.3% accretive to the combined company's cash earnings
      per share for fiscal year 2001; and

    - between 3.9% and 10.4% accretive to the combined company's cash earnings
      per share for fiscal year 2002.

    OTHER FACTORS AND COMPARATIVE ANALYSES.  In its presentation to the Sterling
Software Board, Goldman, Sachs & Co. reviewed some other factors and comparative
analyses, including, among other things, (i) the historical and pro forma
financial profile of Sterling Software and Computer Associates to certain other
software companies, (ii) the ownership profile of Sterling Software and Computer
Associates, (iii) the forward P/E history of Sterling Software and Computer
Associates and (iv) analysts' reports, including earnings estimates, with
respect to Sterling Software and Computer Associates.

    The preparation of a fairness opinion is a complex process involving various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances
and, therefore, is not necessarily susceptible to partial analysis or summary
description. Selecting portions of the analyses or of the summary set forth
above, without considering the analysis as a whole, could create an incomplete
view of the processes underlying Goldman, Sachs & Co.'s opinion. In arriving at
its fairness determination, Goldman, Sachs & Co. considered the results of all
such analyses and did not attribute any particular weight to any factor or
analysis considered by it; rather, Goldman, Sachs & Co. made its determination
as to fairness on the basis of its experience and professional judgment after
considering the results of all such analyses. No company or transaction used in
the above analyses is directly comparable to Sterling Software or the
contemplated transaction. The analyses were prepared solely for purposes of
Goldman, Sachs & Co. providing its opinion to the Sterling Software Board as to
the fairness, from a financial point of view, of the consideration to be
received by the holders of Sterling Software Common Stock pursuant to the Merger
Agreement and do not purport to be appraisals or necessarily reflect the prices
at which businesses or securities actually may be sold. Analyses based on
forecasts of future results are not necessarily indicative of actual future
results, which may be significantly more or less favorable than suggested by
such analyses. Because such analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of the parties or
their respective advisors, none of Sterling Software, Goldman, Sachs & Co. or
any other person assumes responsibility if future results

                                       36
<PAGE>
are materially different from those forecast. As described above, the opinion of
Goldman, Sachs & Co. to the Sterling Software Board was among many factors taken
into consideration by the Sterling Software Board in making its determination to
approve the Merger Agreement.

        (c) INTENT TO TENDER.

    To Sterling Software's knowledge, after reasonable inquiry and in view of
the obligations under the Tender Agreement, all executive officers, directors,
affiliates and subsidiaries of Sterling Software will tender pursuant to the
Offer all Shares held of record or beneficially owned by them (other than
options to acquire Shares).

ITEM 5. PERSONS/ASSETS, RETAINED, EMPLOYED, COMPENSATED OR USED.

    GOLDMAN LETTER AGREEMENT.  Sterling Software engaged Goldman, Sachs & Co.,
pursuant to the terms of the Goldman Letter Agreement, to assist Sterling
Software as its financial advisor in connection with the possible sale of all or
a portion of Sterling Software (a "Transaction").

    Pursuant to the terms of the Goldman Letter Agreement, Sterling Software
agreed to pay Goldman, Sachs & Co. (i) a cash fee of $250,000, payable upon the
signing of the Goldman Letter Agreement, and (ii) a fee equal to 0.50% of the
aggregate consideration paid in a Transaction such as the Offer and the Merger.
Assuming a transaction value per share of $39.50 and based on Sterling
Software's most recent unaudited balance sheet, the total fee payable by
Sterling Software to Goldman, Sachs & Co. in connection with the Offer and the
Merger would equal $18,761,144, against which the $250,000 fee would be
credited.

    Sterling Software has also agreed to reimburse Goldman, Sachs & Co. for
reasonable out-of-pocket expenses, including the reasonable fees and
disbursements of its legal counsel, and to indemnify Goldman, Sachs & Co. and
related parties against certain liabilities arising out of or in connection with
Goldman, Sachs & Co.'s engagement.

    BROADVIEW LETTER AGREEMENT.  Sterling Software engaged Broadview, pursuant
to the terms of a letter agreement, dated as of January 21, 2000 (the "Broadview
Letter Agreement"), to assist Sterling Software as its financial advisor in
connection with Sterling Software's consideration of potential acquisition
offers with respect to Sterling Software. Pursuant to the terms of the Broadview
Letter Agreement, Sterling Software agreed to pay Broadview a fee of
$2 million, contingent upon the closing of a business combination or other
transaction involving Sterling Software. Sterling Software has also agreed to
reimburse Broadview for reasonable out-of-pocket expenses including, without
limitation, the reasonable fees and disbursements of its legal counsel, and to
indemnify Broadview and related parties against certain liabilities, actions and
claims arising out of Broadview's engagement by Sterling Software pursuant to
the Broadview Letter Agreement.

    Except as set forth above, neither Sterling Software nor any person acting
on its behalf has employed, retained or agreed to compensate any person or class
of persons to make solicitations or recommendations in connection with the Offer
or the Merger.

Sterling Software, Inc., a Delaware corporation (the "Sterling Software"). It is
being furnished in connection with an Agreement and Plan of Merger, dated as of
February 14, 2000 (the "Merger Agreement"), by and among Computer Associates

effect to the election of any additional directors pursuant to this provision)
and (ii) the percentage that the number of Shares owned by Computer Associates
or Silversmith Acquisition Corp. (including Shares accepted for exchange) bears
to the total number of Shares outstanding, and Sterling Software will take all
action necessary to cause Computer Associates' designees to be elected or
appointed to the Board,

to the effective time of the Merger (the "Effective Time"), two members (each, a
"Continuing Director") who were directors of Sterling Software prior to
consummation of the Offer, shall remain as directors of Sterling Software until
the Effective Time. If the number of Continuing Directors is reduced to less
than two for any reason prior to the Effective Time, the remaining and departing
Continuing Directors shall be entitled to designate a person to fill the
vacancy.

    The directors of Silversmith Acquisition Corp. at the Effective Time shall
be the directors of the Surviving Corporation, until the earlier of their
resignation or removal or until their successors are duly elected and qualified.

Computer Associates Designees to the Sterling Software Board from the directors
and executive officers of Computer Associates and/or Silversmith Acquisition
Corp. listed in Annex A to the Exchange Offer, a copy of which is being mailed

and persons who own more than 10% of Sterling Software's outstanding Common
Stock, to file initial reports of ownership and reports of changes in ownership
of Common Stock with the Securities and Exchange Commission (the "SEC") and the
New York Stock Exchange (the "NYSE"). Such persons are required by SEC
regulations to furnish Sterling Software with copies of all Section 16(a)
reports they file.

    Based solely on its review of such reports received by Sterling Software
with respect to fiscal 1999 and written representations from such reporting
persons, Sterling Software believes that, except as noted herein, all reports
required to be filed under Section 16(a) have been timely filed by such persons.

CHANGE IN CONTROL, SEVERANCE AND EMPLOYMENT AGREEMENTS

    Sterling Software has entered into an agreement (a "Change in Control
Agreement") with each of the Named Executive Officers and certain of its other
officers. Each Change in Control Agreement provides for certain payments and
benefits upon the termination of employment of such person with Sterling
Software following a Change in Control (as defined in such agreement). Each
Change in Control Agreement covers termination within a specified number of
years after the date of a Change in Control and requires Sterling Software to
pay to such officer, if prior to the expiration of such period his or her
employment is terminated with or without cause by Sterling Software (other than
upon such officer's death) or by such officer upon the occurrence of certain
constructive termination events, a lump-sum amount equal to a multiple of such
officer's annual cash compensation and to continue all benefits and perquisites
for a specified number of months. In addition, if any payments (including
payments under the Change in Control Agreement, any stock option agreement or
otherwise) to such officer are determined to be "excess parachute payments"
under the Internal Revenue Code of 1986, as amended (the "Code"), such officer
would be entitled to receive an additional payment (net of income taxes) to
compensate such officer for any excise tax imposed by the Code on such payments.
The specified number of years, the multiple and the specified number of months
referred to above are seven, 700% and 84, in the case of each of
Messrs. Williams, Sam Wyly and Charles J. Wyly, Jr.; five, 500% and 60, in the
case of Mr. Tolari; and two, 200% and 24 in the case of Mr. Harvey.

    Sterling Software has also entered into an agreement (the "CEO Agreement")
with Sterling L. Williams, providing for a minimum base salary (subject to
mutually agreeable annual increases) and certain benefits, plus such bonuses and
other benefits which Sterling Software and Mr. Williams may agree upon.
Mr. Williams' base salary for fiscal 1999 was $800,000. Under the terms of the
CEO Agreement, upon the termination of Mr. Williams' employment by (i) Sterling
Software (with or without cause) or (ii) Mr. Williams as a result of a reduction
in his compensation or of the nature or scope of his authority or duties, the
CEO Agreement will convert into a seven-year consulting agreement. In such
event, Mr. Williams would be entitled to continue receiving compensation and
benefits at the levels specified in the CEO Agreement. Prior to the expiration
of its seven-year term, the consulting agreement may be terminated by
Mr. Williams at any time and by Sterling Software at Mr. Williams' death. In the
event of termination of Mr. Williams' employment following a Change in Control,
at Mr. Williams' option, the terms of his Change in Control Agreement may govern
such termination in lieu of the conversion of the CEO Agreement into a
consulting agreement. In the event of a Change in Control following conversion
of the CEO Agreement into a consulting agreement, Mr. Williams would have the
option of terminating the consulting agreement and would be entitled to receive
a lump-sum amount equal to all compensation due through the unexpired portion of
the seven-year consulting agreement.

    Sterling Software has entered into an agreement (a "Severance Agreement")
with Mr. Tolari, Mr. Harvey and certain of its other officers (other than
Messrs. Williams, Sam Wyly and Charles J. Wyly, Jr.), providing for the
continued compensation of such officer in the event that Sterling Software
terminates his or her employment, with or without cause. Each Severance
Agreement expires a specified number of years after the date on which notice of
termination is given to him or her by Sterling Software and requires Sterling
Software to continue to pay such officer, following his or her termination from
employment by Sterling Software, for a specified number of months, the salary,
bonus and certain benefits in effect prior to the termination of his or her
employment. The specified number of years and months referred to above are five
and 60 for Mr. Tolari and two and 24 for Mr. Harvey.

In the event of a termination of employment following a Change in Control, at
the officer's option, the terms of his or her Change in Control Agreement may
govern such termination in lieu of the terms of his or her Severance Agreement.

CHANGE IN CONTROL AGREEMENT AMENDMENTS

    As part of the Merger Agreement negotiations, Computer Associates requested
that the Change in Control Agreements be amended. In particular, Computer
Associates requested that each executive officer of Sterling Software, as well
as Evan A. Wyly, a director of Sterling Software, and certain other officers of
Sterling Software (collectively, the "Executives") waive his or her right to a
continuation of benefits and perquisites (except medical coverages) and that the
agreements be amended to add a non-competition covenant in respect of certain
Executives and non-solicitation and confidentiality covenants in respect of all
the Executives. On February 14, 2000, Sterling Software, Computer Associates,
and each Executive agreed to amend the Change in Control Agreements, effective
as of the consummation of the Offer. Such amendments, which were required by
Computer Associates as a condition to executing the Merger Agreement, become
effective upon consummation of the Offer. In general, such amendments confirmed
and, in certain respects reduced, the Executives' benefits and imposed upon the
Executives a non-competition covenant and other covenants to which they were not
previously subject. The amendments provide, among other things, that:

    - each Executive will be paid a lump sum in cash upon a qualifying
      termination of employment in satisfaction of all severance pay and in lieu
      of the continuation of certain benefits and perquisites to which he or she
      would otherwise have been entitled pursuant to such Executive's Change in
      Control Agreement. As to certain of the Executives, twenty-five percent of
      the payment is in consideration for entering into a non-competition
      covenant. The payments to be provided to each executive officer of
      Sterling Software and Evan A. Wyly upon a qualifying termination of
      employment are as follows:

      with Sterling Software or solicit Sterling Software employees for a
      specified period. An Executive may request a waiver of the non-competition
      provision after a certain time and such waiver shall not be unreasonably
      withheld by Sterling Software. The relevant non-competition and
      non-solicitation periods are as follows:

    - each Executive must keep Sterling Software information confidential;

    - each Executive is entitled to a gross-up on any excise tax under
      Section 4999 of the Code which may be imposed on any payments and benefits
      received by the Executive in connection with the Offer or the Merger. If
      the Offer is consummated on March 20, 2000, and assuming each Executive
      were to incur a qualifying termination of employment immediately following
      that date and a per share consideration to be received by Sterling
      Software stockholders in the Offer and the Merger of $39.50 in Computer
      Associates Common Stock, the approximate gross-up payments that would be
      payable to certain Executives (those expected to be subject to excise tax)
      are as follows:

    Ms. Morton and Messrs. Tolari and Harvey have each delivered Computer
Associates a letter whereby they have agreed to elect to receive cash
consideration (rather than convert their options) to the extent that failure to
so elect would result in an incremental increase of such individual's excise tax
liability.

    In addition:

    - Mr. Williams' change in control severance agreement has been amended to
      require Sterling Software to transfer to him, upon a qualifying
      termination of employment, the ownership of the life insurance policy
      concerning him which has been funded by Sterling Software;

    - Mr. Sam Wyly's change in control severance agreement has been amended to
      require Sterling Software to pay him, upon a qualifying termination of
      employment, an amount in cash equal to the value of the split dollar life
      insurance policy concerning him which is held by Sterling Software; and

    - Ms. Morton's change in control severance agreement has been amended to
      have Sterling Software acknowledge her entitlement to certain retiree
      medical benefits.

SERP II

    In connection with its acquisition of Informatics General Corporation
("Informatics") in 1985, Sterling Software retained the Informatics Supplemental
Executive Retirement Plan II ("SERP II"). As of December 31, 1999, Geno P.
Tolari had accrued approximately 29 years of service under SERP II. None of the
other Named Executive Officers participates or is eligible to participate in
SERP II. The annual benefit payable upon retirement at age 65 or above under
SERP II is equal to the lesser of the following amounts: (i) 2% of the
participant's "final average pay," which is equal to the highest average of the
participant's base salary plus the participant's bonuses (up to a maximum bonus
amount not to exceed 50% of the participant's base salary) over three
consecutive years of service, multiplied by the participant's years of service
and (ii) 50% of the participant's final average pay less the annuity equivalent
of the participant's account balance under the Sterling Software, Inc.
Subsidiary Retirement Plan (a former Informatics plan) as of June 30, 1987 (plus
interest) and the annuity equivalent of the assumed Sterling Software matching
contribution under the Savings Plan thereafter, plus interest (collectively, the
"annuity offset"). Benefits paid under SERP II are adjusted in the event of
disability or retirement prior to age 65. Benefits are also adjusted annually,
upward or downward, to the extent that the increase or decrease, if any, in the
Consumer Price Index for the preceding calendar year compared to the Consumer
Price Index for the next preceding calendar year exceeds 5%. Amounts paid under
SERP II are taxable as income. SERP II is not funded and benefits are paid as
they become due. Benefits under SERP II are paid in the form of a joint and 50%
survivor annuity.

    The following table shows the estimated annual benefits payable upon
retirement at age 65 to Mr. Tolari under SERP II for the indicated level of
three-year average annual compensation and various periods of service. The
amounts shown in the table may be subject to the annuity offset, the amount of
which depends on the pay history of Mr. Tolari and the return on amounts held in
the Savings Plan.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    Pursuant to a consulting arrangement with Sterling Software, Michael C.
French, a director of Sterling Software, received from Sterling Software a
non-refundable retainer of $17,500 per month during fiscal 1999 for his
assistance in significant acquisitions and other matters relating to Sterling
Software. Mr. French received $1,000 per month as an employee of Sterling
Software, which amount is deducted from amounts paid to him as a retainer.

PERSONAL AND CONFIDENTIAL

February 14, 2000

Board of Directors
Sterling Software Inc.
300 Crescent Court, Suite 1200
Dallas, TX 75201-7832

Gentlemen:

You have requested our opinion as to the fairness from a financial point of view
to the holders of the outstanding shares of Common Stock, par value $0.10 per
share (the "Company Common Stock"), of Sterling Software Inc. (the "Company") of
the Consideration (as defined below) to be received by holders of shares of
Company Common Stock pursuant to the Agreement and Plan of Merger, dated as of
February 14, 2000, among Computer Associates International, Inc. (the "Parent"),
Silversmith Acquisition Corp., a wholly-owned subsidiary of Parent ("Merger
Subsidiary"), and the Company (the "Agreement"). The Agreement provides for
(i) an exchange offer for all of the outstanding shares of Company Common Stock
(the "Exchange Offer") pursuant to which Parent will offer for each share of
Company Common Stock (A) a number of shares of Common Stock, par value $0.10 per
share ("Parent Common Stock"), of Parent equal to the Exchange Ratio (as defined
below) and (B), if Parent shall have made the Cash Election (as defined below),
the Cash Election Amount (as defined below), and (ii) subsequent to the Exchange
Offer, a merger of Merger Subsidiary with and into the Company (the "Merger")
pursuant to which each remaining share of Company Common Stock will be converted
into the right to receive (A) the Exchange Ratio in Parent Common Stock and (B),
if Parent shall have made the Cash Election, the Cash Election Amount. Under the
Agreement, the Exchange Ratio will be 0.5634, provided that if the Average
Parent Trading Price (as defined in the Agreement) (x) is less than $63.10,
then, unless Parent makes the Cash Election, the Exchange Ratio shall equal the
quotient of (A) $35.55 divided by (B) the Average Parent Trading Price, or
(y) is greater then $77.12, then the Exchange Ratio shall equal the quotient of
(A) $43.45 divided by (B) the Average Parent Trading Price. The Agreement
further provides that if the Average Parent Trading Price is less than $63.10,
Parent may elect (the "Cash Election") to reduce the Exchange Ratio that would
otherwise be in effect in both the Exchange Offer and the Merger by paying in
cash (such amount of cash per share, the "Cash Election Amount") all or any
portion of the excess of (x) $ 35.55 over (y) the product of (A) 0.5634 and
(B) the Average Parent Trading Price, and if the Parent makes the Cash Election,
the Exchange Ratio shall be adjusted to equal the quotient of (x) the excess of
(A) $35.55 over (B) the Cash Election Amount divided by (y) the Average Parent
Trading Price. For purposes of this opinion, Consideration shall mean the
Exchange Ratio in Parent Common Stock or, if the Parent makes the Cash Election,
the combination of the Exchange Ratio in Parent Common Stock and the Cash
Election Amount.

Goldman, Sachs & Co., as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. We are familiar with
the Company having provided certain investment banking services to the Company
from time to time, including having acted as its financial advisor in connection
with, and having participated in certain of the negotiations leading to, the
Agreement. Goldman, Sachs & Co. provides a full range of financial advisory and
securities services and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of the Company or Parent for its own account and for the accounts of
customers. As of the date hereof, Goldman, Sachs & Co. accumulated a long
position of 9,100 shares of Company Common Stock against which Goldman, Sachs &
Co. is short 1,700 shares of Company Common Stock, a long position of 116,375
shares of Parent Common Stock, against which Goldman, Sachs & Co. is short
182,218 shares of Parent Common Stock, a short position of $3,000,000 aggregate
principal amount of 6.50% bonds due April of 2008 of Parent and a short position
of options to purchase 10,000 shares of Common Stock of Parent. Goldman,
Sachs & Co. may provide investment banking services to Parent and its
subsidiaries in the future.

In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of the
Company and the Parent for the five fiscal years ended September 30, 1999 and
March 31, 1999, respectively; certain interim reports to stockholders and
Quarterly Reports on Form 10-Q of the Company and Parent; certain other
communications from the Company and Parent to their respective stockholders; and
certain internal financial analyses and certain base case and risk adjusted case
forecasts for the Company prepared by its management (the "Forecasts"),
including certain cost savings and operating synergies projected by the
management of the Company to result from the transaction contemplated by the
Agreement. We also have held discussions with members of the senior management
of the Company and Parent regarding their assessment of the strategic rationale
for, and the potential benefits of, the transaction contemplated by the
Agreement and the past and current business operations, financial condition and
future prospects of their respective companies. In addition, we have reviewed
the reported price and trading activity for the Company Common Stock and the
Parent Common Stock, compared certain financial and stock market information for
the Company and Parent with similar information for certain other companies the
securities of which are publicly traded, reviewed the financial terms of certain
recent business combinations in the software industry specifically and in other
industries generally and performed such other studies and analyses as we
considered appropriate.

We have relied upon the accuracy and completeness of all of the financial and
other information discussed with or reviewed by us and have assumed such
accuracy and completeness for purposes of rendering this opinion. In that
regard, we have assumed with your consent that the Forecasts have been
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of the Company. As you are aware, Parent did not make available to
us its projections of expected future financial performance. Accordingly, our
review of such matters was limited to discussions with members of the senior
management of Parent regarding certain research analyst estimates of future
financial performance of Parent. In addition, we have not made an independent
evaluation or appraisal of the assets and liabilities of the Company or Parent
or any of their subsidiaries and, we have not been furnished with any such
evaluation or appraisal. Our advisory services and the opinion expressed herein
are provided for the information and assistance of the Board of Directors of the
Company in connection with its consideration of the transaction contemplated by
the Agreement and such opinion does not constitute a recommendation as to
whether or not any holder of shares of Company Common Stock should tender such
Company Common Stock in the Exchange Offer or, if applicable, how any such
holder should vote with respect to the Merger.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the
Consideration to be received by holders of Company Common Stock pursuant to the
Agreement is fair from a financial point of view to such holders.

Very truly yours,

Dear Stockholders:

    On behalf of the Board of Directors of Sterling Software, Inc. ("Sterling
Software"), I am pleased to inform you that on February 14, 2000, Sterling
Software entered into an Agreement and Plan of Merger (the "Merger Agreement")
providing for the acquisition of Sterling Software by Computer Associates
International, Inc. ("Computer Associates").

    As required by the Merger Agreement, Computer Associates, through a
wholly-owned subsidiary, has commenced an offer (the "Offer") to exchange 0.5634
shares (the "Exchange Ratio") of common stock, par value $.10 per share, of
Computer Associates (the "Computer Associates Common Stock"), for each
outstanding share of common stock, par value $.10 per share, together with the
associated preferred stock purchase rights, of Sterling Software (the "Shares"),
subject to adjustment as set forth below. If the average trading price of
Computer Associates Common Stock for the designated period prior to the closing
of the Offer (i) is greater than $77.12, the Exchange Ratio will be reduced so
that each Share tendered in the Offer will be exchanged for such number of
shares of Computer Associates Common Stock as is designed to equal $43.45 at the
time the Exchange Ratio is set based on the average trading price of Computer
Associates' shares, or (ii) is less than $63.10, unless Computer Associates
makes the Cash Election (as described below), the Exchange Ratio will be
increased so that each Share tendered in the Offer will be exchanged for such
number of shares of Computer Associates Common Stock as is designed to equal
$35.55 at the time the Exchange Ratio is set based on the average trading price
of Computer Associates' shares. If the average trading price of Computer
Associates Common Stock is less than $63.10, Computer Associates may elect (the
"Cash Option") to reduce the Exchange Ratio that would otherwise be in effect
and pay cash in substitution for Computer Associates' shares for all or a
portion of the shortfall of Computer Associates' share price below $63.10 (the
"Cash Option Amount"). Consummation of the Offer is subject to, among other
things, at least a majority of the Shares, determined on a fully diluted basis,
being validly tendered and not withdrawn prior to the expiration of the Offer.

    Pursuant to the Merger Agreement, following the completion of the Offer and
the satisfaction or waiver of certain other conditions, the subsidiary of
Computer Associates will be merged with and into Sterling Software (the
"Merger"), with Sterling Software being the surviving corporation. In the
Merger, each outstanding Share (other than Shares held by Computer Associates
and stockholders who perfect appraisal rights under Delaware law, which will be
available if Computer Associates elects the Cash Option or if the Merger is
completed pursuant to Section 253 of the Delaware General Corporation Law) will
be converted into the right to receive such number of fully paid and
nonassessable shares of Computer Associates as is equal to the Exchange Ratio
finally established for the Offer and, if Computer Associates has elected the
Cash Option in connection with the Offer, an amount in cash equal to the Cash
Option Amount.

    YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, HAS
UNANIMOUSLY DETERMINED THAT THE TRANSACTIONS CONTEMPLATED BY THE MERGER
AGREEMENT, INCLUDING THE OFFER AND THE MERGER, ARE ADVISABLE, FAIR TO AND IN THE
BEST INTEREST OF STERLING SOFTWARE'S STOCKHOLDERS, AND UNANIMOUSLY

RECOMMENDS THAT STERLING SOFTWARE'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER
THEIR SHARES PURSUANT TO THE OFFER.

    In arriving at its recommendation, the Board of Directors gave careful
consideration to a number of factors as described in the enclosed
Solicitation/Recommendation Statement on Schedule 14D-9, including the fairness
opinion of Goldman, Sachs & Co., a financial advisor to Sterling Software, that,
subject to the assumptions, factors and limitations set forth in the opinion,
the consideration to be received by Sterling Software's stockholders pursuant to
the Merger Agreement is fair from a financial point of view to Sterling
Software's stockholders.

    Accompanying this letter and Schedule 14D-9 are (i) an Information
Statement, which is attached as Schedule I to the Schedule 14D-9, (ii) the
fairness opinion of Goldman, Sachs & Co., which is attached as Schedule III to
the Schedule 14D-9, and (iii) Computer Associates' Exchange Offer, dated
February 22, 2000, together with related materials, including the Letter of
Transmittal to be used for tendering Shares. These documents set forth the terms
and conditions of the Offer and describe the reasons for the recommendation of
the Board of Directors and certain other factors that stockholders should
consider. We urge you to read the enclosed materials carefully.

    If you need assistance with the tendering of your Shares, please contact the
information agent for the Offer, MacKenzie Partners, Inc., at its address or
telephone number appearing on the back cover of the Exchange Offer.

    On behalf of the Board of Directors and management of Sterling Software, we
thank you for your support.

                                          Very truly yours,

                      CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS AMENDMENT TO CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Amendment"),
dated as of February 14, 2000, by and among Sterling Software, Inc., a
Delaware corporation (the "Company"), Computer Associates International,
Inc., a Delaware corporation (the "Parent") and Sam Wyly (the "Executive").

                                   WITNESSETH:

         WHEREAS, the Company and the Executive are parties to a Change in
Control Severance Agreement, dated as of November 15, 1999 (the "Agreement");
and

         WHEREAS, the Company, the Parent and the Executive desire to amend
the Agreement as set forth in this Amendment;

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of
                  February 14, 2000, by and among the Parent, Silversmith
                  Acquisition Corp. and the Company) is not consummated.

         2.       The Agreement is hereby amended by replacing every occurrence
                  of the term "Employee Benefits" with the term "Medical
                  Benefits" and by the addition of a definition of Medical
                  Benefits as follows:

         (c)      "Medical Benefits" means the medical, dental, health,
                  hospital, disability and vision benefits provided under any
                  and all benefit policies, plans, programs or arrangements of
                  the Company that may now exist or any successor policies,
                  plans, programs or arrangements that may be adopted hereafter
                  by the Company in which the Executive is entitled to
                  participate or in which the Executive becomes entitled to
                  participate.

<PAGE>

         3.       Section 4(a)(i) is hereby amended to read as follows:

         (i)      pay to the Executive, within five (5) business days after the
                  Termination Date, a lump sum payment in an amount equal to
                  $15,899,901 as satisfaction in full for Executive's severance
                  pay and loss of certain perquisites and benefits that would
                  otherwise have been enjoyed by the Executive and for the
                  execution of the Executive's non-competition covenant in
                  Section 10 hereof. The parties agree that twenty-five (25)
                  percent of the lump sum payment shall be allocable to, and
                  deemed as consideration for, the Executive's non-competition
                  covenant in Section 10 hereof.

         4.       Section 4(a)(ii) is hereby amended in its entirety to read as
                  follows:

         (ii)     for 84 months following the Termination Date, arrange at its
                  sole expense, to provide the Executive with Medical Benefits
                  that are substantially similar to the better of (when
                  considered in the aggregate) (x) those Medical Benefits which
                  the Executive was receiving or entitled to receive immediately
                  prior to the Change in Control, or (y) those Medical Benefits
                  which the Executive was receiving or entitled to receive
                  immediately prior to the Termination Date. If and to the
                  extent that any Medical Benefit described above in this
                  Section 4(a)(ii) cannot be provided under any applicable law
                  or regulation or under any policy, plan, program or
                  arrangement of the Company, then the Company will take all
                  action necessary to ensure that such Medical Benefit is
                  provided through other means to the Executive, his dependents
                  and beneficiaries, as applicable.

         5.       Section 4(a)(iv) of the Agreement is hereby amended to read in
                  its entirety as follows:

         (iv)     pay to the Executive, within five (5) business days of the
                  Termination Date, a lump sum in cash in an amount equal to the
                  amount accrued on the books of the Company in respect of the
                  Split Dollar Life Insurance policy applicable to the
                  Executive.


                                       2
<PAGE>

         6.       The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

         7.       The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):

10.  NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges
that reasonable limits on his ability to engage in activities which are
competitive with the Company are warranted in order to protect the Company's
trade secrets and proprietary information and are warranted in order to
protect the Company in developing and maintaining its reputation, good will
and status in the marketplace. In that regard, during the 60 months following
the Termination Date (the "Continuation Period"), the Executive will not
directly or indirectly, on Executive's own behalf or in the service of or on
behalf of any other individual or entity, either as a proprietor, employee,
agent, independent contractor, consultant, director, officer, partner or
stockholder (other than a stockholder of a corporation listed on a national
securities exchange or whose stock is regularly traded in the
over-the-counter market, provided that the Executive at no time owns,
directly or indirectly, in excess of 5% of the outstanding stock of any class
of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by
the Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by
the Company subsequent to the Effective Time and in which the Executive
actively participated, recognizing that the Company offers products and
services globally ("Competitive Activities"), including, without limitation,
(A) selling goods or rendering services of the type (or similar to the type)
sold or rendered by the Company, whether by means of electronic, traditional
or other form of commerce; (B) soliciting any person or entity that is a
current or prospective customer or has been a customer, in each case, of the
Company, while the Executive has been employed by the Company (provided that
it shall not be deemed a breach of this Agreement if the Executive solicits
such customers for goods or services unrelated to the Competitive Activities)
and (C) assisting any person in any way to do, or attempt to do, anything
prohibited by clauses (A) or (B) above; or


                                       3
<PAGE>

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior
to the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of
the Effective Time, and may engage in any activities or businesses for which
the Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of three years from the date
the Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's
lines of businesses.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by
the Company, whether in written, oral or other form. "Confidential
Information" shall mean information about the Company, and its clients and
customers that is not disclosed by the Company for financial reporting
purposes and that was learned by the Executive in the course of employment
with the Company, including (without limitation) any proprietary knowledge,
product and service designs, trade secrets, manuals, technical information
and plans, contracts, systems, procedures, databases, electronic files, disks
and printouts, correspondence, internal reports, personnel files, information
about Company employees relating to their education, experience, skills,
abilities, compensation and benefits, and inter-personal relationships with
suppliers to and customers of Company, sales and advertising material,
business plans, marketing plans, financial data (including without limitation
the revenues, costs or profits associated with services), customer and
industry lists, customer information, customer lists coupled with product or
service pricing, customer contracts, supplier contacts and other contact
information, pricing policies, supplies, agents, risk analyses, engineering
information and computer screen designs and computer input and output
specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges
that such Confidential Information is specialized, unique in nature and of
great value to the Company, and that such information gives the Company a
competitive advantage. The Executive's obligations under this Section 10(c)
shall survive the termination of the Continuation Period.


                                       4
<PAGE>

                   (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of
the Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.

                   (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any
reasonable action by, and will cooperate with, the Company to obtain an
appropriate protective order or other reliable assurance that confidential
treatment will be accorded the Confidential Information. If, failing the
entry of a protective order or the receipt of a waiver hereunder, the
Executive is, in the opinion of Executive's counsel, compelled by law to
disclose a portion of the Confidential Information, the Executive may
disclose to the relevant tribunal without liability hereunder that portion of
the Confidential Information which counsel advises the Executive he is
legally required to disclose, and each of the parties hereto agrees to
exercise such party's best efforts to obtain assurance that confidential
treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any
term or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or
arbitration panel making such determination shall have the power to reduce
the scope, duration or area or the term or provision, to delete specific
words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is a valid and enforceable term or
provision, and this Section 10 shall be enforceable as so modified.


                                       5
<PAGE>

         (e) In the event of a breach or threatened breach by the Executive
of the provisions of this Section 10, the Company's remedies in respect of
such breach or threatened breach shall be limited to injunctive relief (and
the Executive acknowledges that the Company may not have an adequate remedy
at law and may seek injunctive relief without the requirement of posting
security) and the recovery of actual damages suffered by the Company as a
result of a breach of this Section 10 by the Executive. Notwithstanding the
foregoing, in no case shall any portion of the lump sum payment set forth in
Section 4(a)(i) or any Gross Up Payment hereunder (or any other payments made
hereunder) be recoverable by the Parent or the Company (or subject to any
set-off, counterclaim or recoupment) in respect of damages resulting from a
breach of this Section 10.

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         8.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of

                  section 4999 of the Code to any payment or benefit provided
                  hereunder. Such payments shall be made within five (5)
                  business days after delivery of the Executive's written
                  requests for payment accompanied with evidence of fees and
                  expenses incurred. The Company's and Parent's obligation
                  with respect to the Gross Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent shall be final, and the Company and the
                  Parent will not seek to recover all or any part of such
                  payment from the Executive, or from whomsoever may be entitled
                  thereto, for any reason whatsoever.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         10.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         11.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same agreement.

                                  AMENDMENT TO
                      CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS AMENDMENT TO CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Amendment"),
dated as of February 14, 2000, by and among Sterling Software, Inc., a Delaware
corporation (the "Company"), Computer Associates International, Inc., a Delaware
corporation (the "Parent") and Charles J. Wyly (the "Executive").


                                   WITNESSETH:

         WHEREAS, the Company and the Executive are parties to a Change in
Control Severance Agreement, dated as of November 15, 1999 (the "Agreement");
and

         WHEREAS, the Company, the Parent and the Executive desire to amend the
Agreement as set forth in this Amendment;

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

          1.   This Amendment shall be of no force and effect if the Offer (as
               defined in the Agreement and Plan of Merger, dated as of February
               14, 2000, by and among the Parent, Silversmith Acquisition Corp.
               and the Company) is not consummated.

          2.   The Agreement is hereby amended by replacing every occurrence of
               the term "Employee Benefits" with the term "Medical Benefits" and
               by the addition of a definition of Medical Benefits as follows:

          (c)  "Medical Benefits" means the medical, dental, health, hospital,
               disability and vision benefits provided under any and all benefit
               policies, plans, programs or arrangements of the Company that may
               now exist or any successor policies, plans, programs or
               arrangements that may be adopted hereafter by the Company in
               which the Executive is entitled to participate or in which the
               Executive becomes entitled to participate.


<PAGE>

          3.   Section 4(a)(i) is hereby amended to read as follows:

          (i)  pay to the Executive, within five (5) business days after the
               Termination Date, a lump sum payment in an amount equal to
               $7,967,093 as satisfaction in full for Executive's severance pay
               and loss of certain perquisites and benefits that would otherwise
               have been enjoyed by the Executive and for the execution of the
               Executive's non-competition covenant in Section 10 hereof. The
               parties agree that twenty-five (25) percent of the lump sum
               payment shall be allocable to, and deemed as consideration for,
               the Executive's non-competition covenant in Section 10 hereof.

          4.   Section 4(a)(ii) is hereby amended in its entirety to read as
               follows:

          (ii) for 84 months following the Termination Date, arrange at its sole
               expense, to provide the Executive with Medical Benefits that are
               substantially similar to the better of (when considered in the
               aggregate) (x) those Medical Benefits which the Executive was
               receiving or entitled to receive immediately prior to the Change
               in Control, or (y) those Medical Benefits which the Executive was
               receiving or entitled to receive immediately prior to the
               Termination Date. If and to the extent that any Medical Benefit
               described above in this Section 4(a)(ii) cannot be provided under
               any applicable law or regulation or under any policy, plan,
               program or arrangement of the Company, then the Company will take
               all action necessary to ensure that such Medical Benefit is
               provided through other means to the Executive, his dependents and
               beneficiaries, as applicable.

          5.   Section 4(a)(iv) of the Agreement is hereby deleted in its
               entirety.

          6.   The Company shall give the Executive the right to purchase (such
               right to remain open until the expiration of thirty (30) days
               from the Termination Date) at current book value, the Company
               vehicle which was customarily provided to the Executive as of
               immediately prior to the Executive's Date of Termination.

          7.   The Agreement is hereby amended by the addition of a new Section
               10 (and amended as necessary in respect of required renumbering):


                                       2
<PAGE>

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the 60 months following the Termination Date
(the "Continuation Period"), the Executive will not directly or indirectly, on
Executive's own behalf or in the service of or on behalf of any other individual
or entity, either as a proprietor, employee, agent, independent contractor,
consultant, director, officer, partner or stockholder (other than a stockholder
of a corporation listed on a national securities exchange or whose stock is
regularly traded in the over-the-counter market, provided that the Executive at
no time owns, directly or indirectly, in excess of 5% of the outstanding stock
of any class of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior to
the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the
Company has given permission in writing, which shall not be unreasonably
withheld


                                       3
<PAGE>

(or delayed) following the expiration of three years from the date the Offer is
consummated, provided Executive's engaging in such activities or business would
not have a material adverse impact on any of the Company's lines of businesses.

     (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,
trade secrets, manuals, technical information and plans, contracts, systems,
procedures, databases, electronic files, disks and printouts, correspondence,
internal reports, personnel files, information about Company employees relating
to their education, experience, skills, abilities, compensation and benefits,
and inter-personal relationships with suppliers to and customers of Company,
sales and advertising material, business plans, marketing plans, financial data
(including without limitation the revenues, costs or profits associated with
services), customer and industry lists, customer information, customer lists
coupled with product or service pricing, customer contracts, supplier contacts
and other contact information, pricing policies, supplies, agents, risk
analyses, engineering information and computer screen designs and computer input
and output specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges that
such Confidential Information is specialized, unique in nature and of great
value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

         (ii) Confidential Information does not include information which (A) is
or becomes part of the public domain other than as a result of the Executive's
disclosure; or (B) becomes available to the Executive on a non-confidential
basis from a source other than the Company, provided that source is not bound
with respect to that information by a confidentiality agreement with the Company
or otherwise prohibited from transmitting that information by a contractual,
legal or other obligation.

         (iii) If the Executive is requested or (in the opinion of Executive's
counsel) required by law or judicial order to disclose any Confidential
Information,

                                       4
<PAGE>

the Executive shall provide the Company with prompt notice of any such
request or requirement so that the Company may seek an appropriate protective
order or waiver of the Executive's compliance with the provisions of this
Section 10(c). The Executive will not oppose any reasonable action by, and
will cooperate with, the Company to obtain an appropriate protective order or
other reliable assurance that confidential treatment will be accorded the
Confidential Information. If, failing the entry of a protective order or the
receipt of a waiver hereunder, the Executive is, in the opinion of
Executive's counsel, compelled by law to disclose a portion of the
Confidential Information, the Executive may disclose to the relevant tribunal
without liability hereunder that portion of the Confidential Information
which counsel advises the Executive he is legally required to disclose, and
each of the parties hereto agrees to exercise such party's best efforts to
obtain assurance that confidential treatment will be accorded such
Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowledges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross-Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.



                                       5

          8.   Parent shall guarantee the Company's obligations pursuant to the
               Agreement, including without limitation, Sections 5 and 7
               thereof.  The Parent and the Company hereby acknowledge that
               the obligations set forth in such Sections will survive any
               termination or expiration of this Agreement or termination of
               Executive's employment for any reason.  Each party will notify
               the other in writing of any claim by the Internal Revenue
               Service or any other taxing authority that, if successful,
               would require the payment by the Company of a Gross-Up Payment.
                Such notification shall be given as soon as practicable but no
               later than ten (10) business days after such party is informed
               in writing of such a claim and such party shall apprise the
               other party of the nature of such claim and the date on which
               such claim is requested to be paid. The Parent and the Company
               shall bear and pay directly all costs and expenses (including
               legal fees and any interest and penalties) incurred in
               connection with any such claim or proceeding, and shall
               indemnify and hold the Executive harmless, on an after-tax
               basis, as provided in Section 5(a), for any Excise Tax or
               income tax (including interest and penalties with respect
               thereto) imposed as a result of such representation and payment
               of costs and expenses.  The Company and the Parent also shall
               pay to the Executive all legal fees and expenses incurred by
               the Executive in connection with any tax audit or proceeding to
               the extent attributable to the application of section 4999 of
               the Code to any payment or benefit provided hereunder.  Such
               payments shall be made within five (5) business days after
               delivery of the Executive's written requests for payment
               accompanied with evidence of fees and expenses incurred.  The
               Company's and Parent's obligation with respect to a Gross-Up
               Payment and reimbursement of related legal fees and expenses
               shall be absolute and unconditional and shall not be affected
               by any circumstances, including, without limitation, any
               setoff, counterclaim, recoupment, defense or other right which
               the Company or the Parent may have against the Executive or
               anyone else. Except where provided herein to the contrary, all
               amounts payable by the Company or the Parent hereunder shall be
               paid without notice or demand.  Each and every payment made
               hereunder by the Company or the Parent shall be final, and the
               Company and the Parent will not seek to recover all or any part
               of such payment from the Executive, or from whomsoever may be
               entitled thereto, for any reason whatsoever.

          9.   Except as amended hereby, all other provisions of the
               Agreement shall remain in full force and effect.

         10.   The validity, interpretation, construction and performance of
               this Amendment will be governed by and construed in accordance
               with the substantive laws of Delaware, without giving effect

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of

         2.       The Agreement is hereby amended by replacing every occurrence
                  of the term "Employee Benefits" with the term "Medical
                  Benefits" and by the addition of a definition of Medical
                  Benefits as follows:

         (c)      "Medical Benefits" means the medical, dental, health,
                  hospital, disability and vision benefits provided under any

                  $12,638,596 as satisfaction in full for Executive's severance
                  pay and loss of certain perquisites and benefits that would
                  otherwise have been enjoyed by the Executive.

         4.       Section 4(a)(ii) is hereby amended in its entirety to read as
                  follows:

         (ii)     for 84 months following the Termination Date (the
                  "Continuation Period"), arrange at its sole expense, to
                  provide the Executive with Medical Benefits that are
                  substantially similar to the better of (when considered in the
                  aggregate) (x) those Medical Benefits which the Executive was
                  receiving or entitled to receive immediately prior to the
                  Change in Control, or (y) those Medical Benefits which the
                  Executive was receiving or entitled to receive immediately
                  prior to the Termination Date. If and to the extent that any
                  Medical Benefit described above in this Section 4(a)(ii)
                  cannot be provided under any applicable law or regulation or
                  under any policy, plan, program or arrangement of the Company,
                  then the Company will take all action necessary to ensure that
                  such Medical Benefit is provided through other means to the
                  Executive, his dependents and beneficiaries, as applicable.

         5.       Section 4(a)(iv) of the Agreement is hereby amended in its

                  insurance policy on the Executive's life funded by the
                  Company.

         6.       The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

         7.       The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the Continuation Period, the Executive will
not directly or indirectly, on Executive's own behalf or in the service of or on
behalf of any other individual or entity, either as a proprietor, employee,
agent, independent contractor, consultant, director, officer, partner or
stockholder (other than a stockholder of a corporation listed on a national
securities exchange or whose stock is regularly traded in the over-the-counter
market, provided that the Executive at no time owns, directly or indirectly, in
excess of 5% of the outstanding stock of any class of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or


                                       3

<PAGE>

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior to
the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the
Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of three years from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's lines
of businesses.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,
trade secrets, manuals, technical information and plans, contracts, systems,
procedures, databases, electronic files, disks and printouts, correspondence,
internal reports, personnel files, information about Company employees relating
to their education, experience, skills, abilities, compensation and benefits,
and inter-personal relationships with suppliers to and customers of Company,
sales and advertising material, business plans, marketing plans, financial data
(including without limitation the revenues, costs or profits associated with
services), customer and industry lists, customer information, customer lists
coupled with product or service pricing, customer contracts, supplier contacts
and other contact information, pricing policies, supplies, agents, risk
analyses, engineering information and computer screen designs and computer input
and output specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges that
such Confidential Information is specialized, unique in nature and of great
value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

                  (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of the
Executive's


                                       4

<PAGE>

disclosure; or (B) becomes available to the Executive on a non-confidential
basis from a source other than the Company, provided that source is not bound
with respect to that information by a confidentiality agreement with the
Company or otherwise prohibited from transmitting that information by a
contractual, legal or other obligation.

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any reasonable
action by, and will cooperate with, the Company to obtain an appropriate
protective order or other reliable assurance that confidential treatment will be
accorded the Confidential Information. If, failing the entry of a protective
order or the receipt of a waiver hereunder, the Executive is, in the opinion of
Executive's counsel, compelled by law to disclose a portion of the Confidential
Information, the Executive may disclose to the relevant tribunal without
liability hereunder that portion of the Confidential Information which counsel
advises the Executive he is legally required to disclose, and each of the
parties hereto agrees to exercise such party's best efforts to obtain assurance
that confidential treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowledges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder


                                       5

<PAGE>

(or any other payments made hereunder) be recoverable by the Parent or the
Company (or subject to any set-off, counterclaim or recoupment) in respect of
damages resulting from a breach of this Section 10.

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         8.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made within
                  five (5) business days after delivery of the Executive's
                  written requests for payment accompanied with evidence of fees
                  and expenses incurred. The Company's and Parent's obligation
                  with respect to a Gross-Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent


                                      6

<PAGE>

                  may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent shall be final, and the Company and the
                  Parent will not seek to recover all or any part of such
                  payment from the Executive, or from whomsoever may be entitled
                  thereto, for any reason whatsoever.

         9.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  CEO Agreement with the Company dated November 15, 1999 and
                  that such agreement shall be terminated as of the date of the
                  consummation of the Offer.

         10.      Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         11.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         12.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same Agreement.

                  Change in Control, or (y) those Medical Benefits which the
                  Executive was receiving or entitled to receive immediately
                  prior to the Termination Date. If and to the extent that any
                  Medical Benefit described above in this Section 4(a)(ii)
                  cannot be provided under any applicable law or regulation or
                  under any policy, plan, program or arrangement of the Company,
                  then the Company will take all action necessary to ensure that
                  such Medical Benefit is provided through other means to the
                  Executive, his dependents and beneficiaries, as applicable.

         5.       Section 4(a)(iv) of the Agreement is hereby deleted in its
                  entirety.

         6.       The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

         7.       The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in


                                        2
<PAGE>

developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the Continuation Period, the Executive will
not directly or indirectly, on Executive's own behalf or in the service of or on
behalf of any other individual or entity, either as a proprietor, employee,
agent, independent contractor, consultant, director, officer, partner or
stockholder (other than a stockholder of a corporation listed on a national
securities exchange or whose stock is regularly traded in the over-the-counter
market, provided that the Executive at no time owns, directly or indirectly, in
excess of 5% of the outstanding stock of any class of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior to
the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the
Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of three years from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's lines
of businesses.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,
trade secrets, manuals, technical information and plans, contracts, systems,
procedures, databases, electronic files, disks and printouts, correspondence,
internal reports, personnel files, information about Company employees relating
to their education, experience, skills, abilities, compensation and benefits,
and inter-personal relationships with suppliers to and customers of Company,
sales and advertising material, business plans, marketing plans, financial data
(including without limitation the revenues, costs or profits associated with
services), customer and industry lists, customer information, customer lists
coupled with product or service pricing, customer contracts, supplier contacts
and other contact information, pricing policies, supplies, agents, risk
analyses, engineering information and computer screen designs and computer input
and output specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges that
such Confidential Information is specialized, unique in nature and of great
value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

                  (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of the
Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any reasonable
action by, and will cooperate with, the


                                        4
<PAGE>

Company to obtain an appropriate protective order or other reliable assurance
that confidential treatment will be accorded the Confidential Information. If,
failing the entry of a protective order or the receipt of a waiver hereunder,
the Executive is, in the opinion of Executive's counsel, compelled by law to
disclose a portion of the Confidential Information, the Executive may disclose
to the relevant tribunal without liability hereunder that portion of the
Confidential Information which counsel advises the Executive he is legally
required to disclose, and each of the parties hereto agrees to exercise such
party's best efforts to obtain assurance that confidential treatment will be
accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowledges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.

         (f)      For the purposes of this Section 10, the term "Company"
includes not only Sterling Software, Inc., but also any subsidiary or
affiliated corporation of Sterling Software, Inc.

         8.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of


                                        5
<PAGE>

                  this Agreement or termination of Executive's employment for
                  any reason. Each party will notify the other in writing of any
                  claim by the Internal Revenue Service or any other taxing
                  authority that, if successful, would require the payment by
                  the Company of a Gross-Up Payment. Such notification shall be
                  given as soon as practicable but no later than ten (10)
                  business days after such party is informed in writing of such
                  a claim and such party shall apprise the other party of the
                  nature of such claim and the date on which such claim is
                  requested to be paid. The Parent and the Company shall bear
                  and pay directly all costs and expenses (including legal fees
                  and any interest and penalties) incurred in connection with
                  any such claim or proceeding, and shall indemnify and hold the
                  Executive harmless, on an after-tax basis, as provided in
                  Section 5(a), for any Excise Tax or income tax (including
                  interest and penalties with respect thereto) imposed as a
                  result of such representation and payment of costs and
                  expenses. The Company and the Parent also shall pay to the
                  Executive all legal fees and expenses incurred by the
                  Executive in connection with any tax audit or proceeding to
                  the extent attributable to the application of section 4999 of
                  the Code to any payment or benefit provided hereunder. Such
                  payments shall be made within five (5) business days after
                  delivery of the Executive's written requests for payment
                  accompanied with evidence of fees and expenses incurred. The
                  Company's and Parent's obligation with respect to a Gross Up
                  Payment and reimbursement of related legal fees and expenses
                  shall be absolute and unconditional and shall not be affected
                  by any circumstances, including, without limitation, any
                  setoff, counterclaim, recoupment, defense or other right which
                  the Company or the Parent may have against the Executive or
                  anyone else. Except where provided herein to the contrary, all
                  amounts payable by the Company or the Parent hereunder shall
                  be paid without notice or demand. Each and every payment made
                  hereunder by the Company or the Parent shall be final, and the
                  Company and the Parent will not seek to recover all or any
                  part of such payment from the Executive, or from whomsoever
                  may be entitled thereto, for any reason whatsoever.

         9.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's


                                        6
<PAGE>

                  Severance Agreement with the Company dated November 15, 1999
                  and that such agreement shall be terminated as of the date of
                  the consummation of the Offer.

         10.      Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         11.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         12.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same agreement.

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of
                  February 14, 2000, by and among the Parent, Silversmith
                  Acquisition Corp. and the Company) is not consummated.

         2.       The Agreement is hereby amended by replacing every occurrence
                  of the term "Employee Benefits" with the term "Medical
                  Benefits" and by the addition of a definition of Medical
                  Benefits as follows:

         (c)      "Medical Benefits" means the medical, dental, health,
                  hospital, disability and vision benefits provided under any

<PAGE>

                  satisfaction in full for Executive's severance pay and loss
                  of certain perquisites and benefits that would otherwise have

                  follows:

         (ii)     for 24 months following the Termination Date (the

                  receiving or entitled to receive immediately prior to the
                  Change in Control, or (y) those Medical Benefits which the
                  Executive was receiving or entitled to receive immediately
                  prior to the Termination Date. If and to the extent that any
                  Medical Benefit described above in this Section 4(a)(ii)
                  cannot be provided under any applicable law or regulation or
                  under any policy, plan, program or arrangement of the Company,
                  then the Company will take all action necessary to ensure that
                  such Medical Benefit is provided through other means to the
                  Executive, his dependents and beneficiaries, as applicable.

         5.       The Company shall give the Executive the right to purchase

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the Continuation Period, the Executive will
not directly or indirectly, on Executive's own behalf or in the service of or on
behalf of any other individual or entity, either as a proprietor, employee,
agent, independent contractor, consultant, director, officer, partner or
stockholder (other than a stockholder of a corporation listed on a national
securities exchange or whose stock is regularly traded in the over-the-counter
market, provided that the Executive at no time owns, directly or indirectly, in
excess of 5% of the outstanding stock of any class of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior to
the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the


                                       3
<PAGE>

Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of one year from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's lines
of businesses.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,

value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any reasonable
action by, and will cooperate with, the Company to obtain an appropriate
protective order or other reliable assurance that confidential treatment will be
accorded the Confidential Information. If, failing the entry of a protective
order or the receipt of a waiver hereunder, the Executive is, in the opinion of
Executive's counsel, compelled by law to disclose a portion of the Confidential
Information, the Executive may disclose to the relevant tribunal without
liability hereunder that portion of the Confidential Information which counsel
advises the Executive he is legally required to disclose, and each of the
parties hereto agrees to exercise such party's best efforts to obtain assurance
that confidential treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowledges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         7.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made within
                  five (5) business days after delivery of the Executive's
                  written requests for payment accompanied with evidence of fees
                  and expenses incurred. The Company's and Parent's obligation
                  with respect to a Gross-Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent


                                       6

                  shall be final, and the Company and the Parent will not seek
                  to recover all or any part of such payment from the Executive,
                  or from whomsoever may be entitled thereto, for any reason
                  whatsoever.

         8.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's Severance Agreement with the Company dated August
                  15, 1997 and that such agreement shall be terminated as of the
                  date of the consummation of the Offer.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

        10.       The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

        11.       This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same Agreement.

         IN WITNESS WHEREOF, the parties have caused this Amendment to be duly

                                  AMENDMENT TO
                      CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS AMENDMENT TO CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Amendment"),
dated as of February 14, 2000, by and among Sterling Software, Inc., a
Delaware corporation (the "Company"), Computer Associates International,
Inc., a Delaware corporation (the "Parent") and Don J. McDermett, Jr. (the
"Executive").

                                   WITNESSETH:

         WHEREAS, the Company and the Executive are parties to a Change in
Control Severance Agreement, dated as of November 15, 1999 (the "Agreement");
and

         WHEREAS, the Company, the Parent and the Executive desire to amend the
Agreement as set forth in this Amendment;

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of
                  February 14, 2000, by and among the Parent, Silversmith
                  Acquisition Corp. and the Company) is not consummated.

         2.       The Agreement is hereby amended by replacing every occurrence
                  of the term "Employee Benefits" with the term "Medical
                  Benefits" and by the addition of a definition of Medical
                  Benefits as follows:

         (c)      "Medical Benefits" means the medical, dental, health,
                  hospital, disability and vision benefits provided under any
                  and all benefit policies, plans, programs or arrangements of
                  the Company that may now exist or any successor policies,
                  plans, programs or arrangements that may be adopted hereafter
                  by the Company in which the Executive is entitled to

                  participate.


<PAGE>



         3.       Section 4(a)(i) is hereby amended to read as follows:

         (i)      pay to the Executive, within five (5) business days after the
                  Termination Date, a lump sum payment in an amount equal to
                  $2,142,053 as satisfaction in full for Executive's severance
                  pay and loss of certain perquisites and benefits that would
                  otherwise have been enjoyed by the Executive and for the
                  execution of the Executive's non-competition covenant in
                  Section 10 hereof. The parties agree that twenty-five (25)
                  percent of the lump sum payment shall be allocable to, and
                  deemed as consideration for, the Executive's non-competition
                  covenant in Section 10 hereof.

         4.       Section 4(a)(ii) is hereby amended in its entirety to read as
                  follows:

         (ii)     for 48 months following the Termination Date, arrange at its
                  sole expense, to provide the Executive with Medical Benefits
                  that are substantially similar to the better of (when
                  considered in the aggregate) (x) those Medical Benefits which
                  the Executive was receiving or entitled to receive immediately
                  prior to the Change in Control, or (y) those Medical Benefits
                  which the Executive was receiving or entitled to receive
                  immediately prior to the Termination Date. If and to the
                  extent that any Medical Benefit described above in this
                  Section 4(a)(ii) cannot be provided under any applicable law
                  or regulation or under any policy, plan, program or
                  arrangement of the Company, then the Company will take all
                  action necessary to ensure that such Medical Benefit is
                  provided through other means to the Executive, his dependents
                  and beneficiaries, as applicable.

5.                The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

6.                The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):


                                        2
<PAGE>


10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the 24 months following the Termination Date
(the "Continuation Period"), the Executive will not directly or indirectly, on
Executive's own behalf or in the service of or on behalf of any other individual
or entity, either as a proprietor, employee, agent, independent contractor,
consultant, director, officer, partner or stockholder (other than a stockholder
of a corporation listed on a national securities exchange or whose stock is
regularly traded in the over-the-counter market, provided that the Executive at
no time owns, directly or indirectly, in excess of 5% of the outstanding stock
of any class of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior to
the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the
Company has given permission in writing, which shall not be unreasonably
withheld


                                       3
<PAGE>


(or delayed) following the expiration of one year from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's lines
of businesses. The Company and Parent expressly agree that the Executive shall
not be in breach of Section 10(a) hereof if the Executive renders legal services
as outside counsel to any business, individual or entity.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,
trade secrets, manuals, technical information and plans, contracts, systems,
procedures, databases, electronic files, disks and printouts, correspondence,
internal reports, personnel files, information about Company employees relating
to their education, experience, skills, abilities, compensation and benefits,
and inter-personal relationships with suppliers to and customers of Company,
sales and advertising material, business plans, marketing plans, financial data
(including without limitation the revenues, costs or profits associated with
services), customer and industry lists, customer information, customer lists
coupled with product or service pricing, customer contracts, supplier contacts
and other contact information, pricing policies, supplies, agents, risk
analyses, engineering information and computer screen designs and computer input
and output specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges that
such Confidential Information is specialized, unique in nature and of great
value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

                (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of the
Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.


                                       4
<PAGE>


                (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any reasonable
action by, and will cooperate with, the Company to obtain an appropriate
protective order or other reliable assurance that confidential treatment will be
accorded the Confidential Information. If, failing the entry of a protective
order or the receipt of a waiver hereunder, the Executive is, in the opinion of
Executive's counsel, compelled by law to disclose a portion of the Confidential
Information, the Executive may disclose to the relevant tribunal without
liability hereunder that portion of the Confidential Information which counsel
advises the Executive he is legally required to disclose, and each of the
parties hereto agrees to exercise such party's best efforts to obtain assurance
that confidential treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowledges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         7.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made within
                  five (5) business days after delivery of the Executive's
                  written requests for payment accompanied with evidence of fees
                  and expenses incurred. The Company's and Parent's obligation
                  with respect to a Gross-Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent


                                       6

                  shall be final, and the Company and the Parent will not
                  seek to recover all or any part of such payment from the
                  Executive, or from whomsoever may be entitled thereto, for any
                  reason whatsoever.

         8.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's Severance Agreement with the Company dated
                  November 15, 1999 and that such agreement shall be terminated
                  as of the date of the consummation of the Offer.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         10.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         11.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same Agreement.

                                  AMENDMENT TO
                      CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS AMENDMENT TO CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Amendment"),
dated as of February 14, 2000, by and among Sterling Software, Inc., a Delaware
corporation (the "Company"), Computer Associates International, Inc., a Delaware
corporation (the "Parent") and B. Carole Morton (the "Executive").

                                   WITNESSETH:

     WHEREAS, the Company and the Executive are parties to a Change in Control
Severance Agreement, dated as of October 22, 1999 (the "Agreement"); and

     WHEREAS, the Company, the Parent and the Executive desire to amend the
Agreement as set forth in this Amendment;

     NOW THEREFORE, the Company, the Parent and the Executive agree as follows:

     1.   This Amendment shall be of no force and effect if the Offer (as
          defined in the Agreement and Plan of Merger, dated as of February 14,
          2000, by and among the Parent, Silversmith Acquisition Corp. and the
          Company) is not consummated.

     2.   The Agreement is hereby amended by replacing every occurrence of the
          term "Employee Benefits" with the term "Medical Benefits" and by the
          addition of a definition of Medical Benefits as follows:

     (c)  "Medical Benefits" means the medical, dental, health, hospital,
          disability and vision benefits provided under any and all benefit
          policies, plans, programs or arrangements of the Company that may now
          exist or any successor policies, plans, programs or arrangements that
          may be adopted hereafter by the Company in which the Executive is
          entitled to participate or in which the Executive becomes entitled to
          participate.

     3.   Section 4(a)(i) is hereby amended to read as follows:

     (i)  pay to the Executive, within five (5) business days after the
          Termination Date, a lump sum payment in an amount equal to

<PAGE>

          $1,306,365 as satisfaction in full for Executive's severance pay and
          loss of certain perquisites and benefits that would otherwise have
          been enjoyed by the Executive.

     4.   Section 4(a)(ii) is hereby amended in its entirety to read as follows:

     (ii) for 24 months following the Termination Date (the "Continuation
          Period"), arrange at its sole expense, to provide the Executive with
          Medical Benefits that are substantially similar to the better of (when
          considered in the aggregate) (x) those Medical Benefits which the
          Executive was receiving or entitled to receive immediately prior to
          the Change in Control, or (y) those Medical Benefits which the
          Executive was receiving or entitled to receive immediately prior to
          the Termination Date. If and to the extent that any Medical Benefit
          described above in this Section 4(a)(ii) cannot be provided under any
          applicable law or regulation or under any policy, plan, program or
          arrangement of the Company, then the Company will take all action
          necessary to ensure that such Medical Benefit is provided through
          other means to the Executive, his dependents and beneficiaries, as
          applicable.

     5.   The Agreement is hereby amended by the addition of a new Section
          4(a)(iv) to read as follows:

     (iv) The Company hereby ratifies, confirms and acknowledges the Executive's
          right and entitlement to retiree health benefits under the Company's
          Employee Health Benefit Plan, as amended on December 31, 1999.

     6.   The Company shall give the Executive the right to purchase (such right
          to remain open until the expiration of thirty (30) days from the
          Termination Date) at current book value, the Company vehicle which was
          customarily provided to the Executive as of immediately prior to the
          Executive's Date of Termination.

     7.   The Agreement is hereby amended by the addition of a new Section 10
          (and amended as necessary in respect of required renumbering):

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with


                                       2
<PAGE>

the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the Continuation Period, the Executive will
not directly or indirectly, on Executive's own behalf or in the service of or on
behalf of any other individual or entity, either as a proprietor, employee,
agent, independent contractor, consultant, director, officer, partner or
stockholder (other than a stockholder of a corporation listed on a national
securities exchange or whose stock is regularly traded in the over-the-counter
market, provided that the Executive at no time owns, directly or indirectly, in
excess of 5% of the outstanding stock of any class of any such corporation):

     (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or

     (ii) solicit (other than pursuant to general, non-targeted advertisements)
any employee of the Company, who was an employee at or prior to the Effective
Time, to leave the employment of the Company.

     (b) Notwithstanding anything to the contrary herein, Executive may remain a
director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the
Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of one year from the date the
Offer is


                                       3
<PAGE>

consummated, provided Executive's engaging in such activities or business would
not have a material adverse impact on any of the Company's lines of businesses.

     (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,
trade secrets, manuals, technical information and plans, contracts, systems,
procedures, databases, electronic files, disks and printouts, correspondence,
internal reports, personnel files, information about Company employees relating
to their education, experience, skills, abilities, compensation and benefits,
and inter-personal relationships with suppliers to and customers of Company,
sales and advertising material, business plans, marketing plans, financial data
(including without limitation the revenues, costs or profits associated with
services), customer and industry lists, customer information, customer lists
coupled with product or service pricing, customer contracts, supplier contacts
and other contact information, pricing policies, supplies, agents, risk
analyses, engineering information and computer screen designs and computer input
and output specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges that
such Confidential Information is specialized, unique in nature and of great
value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

         (ii) Confidential Information does not include information which (A) is
or becomes part of the public domain other than as a result of the Executive's
disclosure; or (B) becomes available to the Executive on a non-confidential
basis from a source other than the Company, provided that source is not bound
with respect to that information by a confidentiality agreement with the Company
or otherwise prohibited from transmitting that information by a contractual,
legal or other obligation.

         (iii) If the Executive is requested or (in the opinion of Executive's
counsel) required by law or judicial order to disclose any Confidential
Information, the Executive shall provide the Company with prompt notice of any
such request or


                                       4
<PAGE>

requirement so that the Company may seek an appropriate protective order or
waiver of the Executive's compliance with the provisions of this Section 10(c).
The Executive will not oppose any reasonable action by, and will cooperate with,
the Company to obtain an appropriate protective order or other reliable
assurance that confidential treatment will be accorded the Confidential
Information. If, failing the entry of a protective order or the receipt of a
waiver hereunder, the Executive is, in the opinion of Executive's counsel,
compelled by law to disclose a portion of the Confidential Information, the
Executive may disclose to the relevant tribunal without liability hereunder that
portion of the Confidential Information which counsel advises the Executive he
is legally required to disclose, and each of the parties hereto agrees to
exercise such party's best efforts to obtain assurance that confidential
treatment will be accorded such Confidential Information.

     (d) If an award by a court or arbitration panel declares that any term or
provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

     (e) In the event of a breach or threatened breach by the Executive of the
provisions of this Section 10, the Company's remedies in respect of such breach
or threatened breach shall be limited to injunctive relief (and the Executive
acknowledges that the Company may not have an adequate remedy at law and may
seek injunctive relief without the requirement of posting security) and the
recovery of actual damages suffered by the Company as a result of a breach of
this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.

     (f) For the purposes of this Section 10, the term "Company" includes not
only Sterling Software, Inc., but also any subsidiary or affiliated corporation
of Sterling Software, Inc.


                                       5

     8.   Parent shall guarantee the Company's obligations pursuant to the
          Agreement, including without limitation, Sections 5 and 7 thereof. The
          Parent and the Company hereby acknowledge that the obligations set
          forth in such Sections will survive any termination or expiration of
          this Agreement or termination of Executive's employment for any
          reason. Each party will notify the other in writing of any claim by
          the Internal Revenue Service or any other taxing authority that, if
          successful, would require the payment by the Company of a Gross-Up
          Payment. Such notification shall be given as soon as practicable but
          no later than ten (10) business days after such party is informed in
          writing of such a claim and such party shall apprise the other party
          of the nature of such claim and the date on which such claim is
          requested to be paid. The Parent and the Company shall bear and pay
          directly all costs and expenses (including legal fees and any interest
          and penalties) incurred in connection with any such claim or
          proceeding, and shall indemnify and hold the Executive harmless, on an
          after-tax basis, as provided in Section 5(a), for any Excise Tax or
          income tax (including interest and penalties with respect thereto)
          imposed as a result of such representation and payment of costs and
          expenses. The Company and the Parent also shall pay to the Executive
          all legal fees and expenses incurred by the Executive in connection
          with any tax audit or proceeding to the extent attributable to the
          application of section 4999 of the Code to any payment or benefit
          provided hereunder. Such payments shall be made within five (5)
          business days after delivery of the Executive's written requests for
          payment accompanied with evidence of fees and expenses incurred. The
          Company's and Parent's obligation with respect to a Gross-Up Payment
          and reimbursement of related legal fees and expenses shall be absolute
          and unconditional and shall not be affected by any circumstances,
          including, without limitation, any setoff, counterclaim, recoupment,
          defense or other right which the Company or the Parent may have
          against the Executive or anyone else. Except where provided herein to
          the contrary, all amounts payable by the Company or the Parent
          hereunder shall be paid without notice or demand. Each and every
          payment made hereunder by the Company or the Parent shall be final,
          and the Company and the Parent will not seek to recover all or any
          part of such payment from the Executive, or from whomsoever may be
          entitled thereto, for any reason whatsoever.

     9.   The Executive agrees as consideration for the Company's and the
          Parent's entry into this Amendment that, effective upon consummation
          of the Offer, the Executive shall be deemed to have waived all rights
          the Executive may have pursuant to the Executive's Severance Agreement
          with the Company dated August 15, 1997 and that such agreement shall
          be terminated as of the date of the consummation of the Offer.

     10.  Except as amended hereby, all other provisions of the Agreement shall
          remain in full force and effect.

     11.  The validity, interpretation, construction and performance of this
          Amendment will be governed by and construed in accordance with the
          substantive laws of Delaware, without giving effect to the conflict of
          laws principles of such State.

     12.  This Agreement may be executed in one or more counterparts, each of
          which shall be deemed to be an original but all of which together will
          constitute one and the same agreement.

                                   WITNESSETH:

         WHEREAS, the Company and the Executive are parties to a Change in
Control Severance Agreement, dated as of October 22, 1999 (the "Agreement");
and

         WHEREAS, the Company, the Parent and the Executive desire to amend
the Agreement as set forth in this Amendment;

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of
                  February 14, 2000, by and among the Parent, Silversmith

         2.       The Agreement is hereby amended by replacing every occurrence
                  of the term "Employee Benefits" with the term "Medical
                  Benefits" and by the addition of a definition of Medical
                  Benefits as follows:

         (c)      "Medical Benefits" means the medical, dental, health,

         3.       Section 4(a)(i) is hereby amended to read as follows:

         (i)      pay to the Executive, within five (5) business days after the
                  Termination Date, a lump sum payment in an amount equal to
                  $921,118 as satisfaction in full for Executive's severance pay
                  and loss of certain perquisites and benefits that would
                  otherwise have been enjoyed by the Executive and for the
                  execution of the Executive's non-competition covenant in
                  Section 10 hereof. The parties agree that twenty-five (25)
                  percent of the lump sum payment shall be allocable to, and
                  deemed as consideration for, the Executive's non-competition
                  covenant in Section 10 hereof.

         4.       Section 4(a)(ii) is hereby amended in its entirety to read as
                  follows:

         (ii)     for 24 months following the Termination Date (the
                  "Continuation Period"), arrange at its sole expense, to
                  provide the Executive with Medical Benefits that are
                  substantially similar to the better of (when considered in the
                  aggregate) (x) those Medical Benefits which the Executive was
                  receiving or entitled to receive immediately prior to the
                  Change in Control, or (y) those Medical Benefits which the
                  Executive was receiving or entitled to receive immediately
                  prior to the Termination Date. If and to the extent that any
                  Medical Benefit described above in this Section 4(a)(ii)
                  cannot be provided under any applicable law or regulation or
                  under any policy, plan, program or arrangement of the Company,
                  then the Company will take all action necessary to ensure that
                  such Medical Benefit is provided through other means to the
                  Executive, his dependents and beneficiaries, as applicable.

         5.       The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

         6.       The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges
that reasonable limits on his ability to engage in activities which are
competitive with


                                       2
<PAGE>

the Company are warranted in order to protect the Company's trade secrets and
proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the Continuation Period, the Executive
will not directly or indirectly, on Executive's own behalf or in the service
of or on behalf of any other individual or entity, either as a proprietor,
employee, agent, independent contractor, consultant, director, officer,
partner or stockholder (other than a stockholder of a corporation listed on a
national securities exchange or whose stock is regularly traded in the
over-the-counter market, provided that the Executive at no time owns,
directly or indirectly, in excess of 5% of the outstanding stock of any class
of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by
the Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by
the Company subsequent to the Effective Time and in which the Executive
actively participated, recognizing that the Company offers products and
services globally ("Competitive Activities"), including, without limitation,
(A) selling goods or rendering services of the type (or similar to the type)
sold or rendered by the Company, whether by means of electronic, traditional
or other form of commerce; (B) soliciting any person or entity that is a
current or prospective customer or has been a customer, in each case, of the
Company, while the Executive has been employed by the Company (provided that
it shall not be deemed a breach of this Agreement if the Executive solicits
such customers for goods or services unrelated to the Competitive Activities)
and (C) assisting any person in any way to do, or attempt to do, anything
prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior
to the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of
the Effective Time, and may engage in any activities or businesses for which
the


                                       3
<PAGE>

Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of one year from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's
lines of businesses.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by
the Company, whether in written, oral or other form. "Confidential
Information" shall mean information about the Company, and its clients and
customers that is not disclosed by the Company for financial reporting
purposes and that was learned by the Executive in the course of employment
with the Company, including (without limitation) any proprietary knowledge,
product and service designs, trade secrets, manuals, technical information
and plans, contracts, systems, procedures, databases, electronic files, disks
and printouts, correspondence, internal reports, personnel files, information
about Company employees relating to their education, experience, skills,
abilities, compensation and benefits, and inter-personal relationships with
suppliers to and customers of Company, sales and advertising material,
business plans, marketing plans, financial data (including without limitation
the revenues, costs or profits associated with services), customer and
industry lists, customer information, customer lists coupled with product or
service pricing, customer contracts, supplier contacts and other contact
information, pricing policies, supplies, agents, risk analyses, engineering
information and computer screen designs and computer input and output
specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges
that such Confidential Information is specialized, unique in nature and of
great value to the Company, and that such information gives the Company a
competitive advantage. The Executive's obligations under this Section 10(c)
shall survive the termination of the Continuation Period.

                  (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of
the Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.


                                       4
<PAGE>

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any
reasonable action by, and will cooperate with, the Company to obtain an
appropriate protective order or other reliable assurance that confidential
treatment will be accorded the Confidential Information. If, failing the
entry of a protective order or the receipt of a waiver hereunder, the
Executive is, in the opinion of Executive's counsel, compelled by law to
disclose a portion of the Confidential Information, the Executive may
disclose to the relevant tribunal without liability hereunder that portion of
the Confidential Information which counsel advises the Executive he is
legally required to disclose, and each of the parties hereto agrees to
exercise such party's best efforts to obtain assurance that confidential
treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any
term or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or
arbitration panel making such determination shall have the power to reduce
the scope, duration or area or the term or provision, to delete specific
words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is a valid and enforceable term or
provision, and this Section 10 shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive
of the provisions of this Section 10, the Company's remedies in respect of
such breach or threatened breach shall be limited to injunctive relief (and
the Executive acknowledges that the Company may not have an adequate remedy
at law and may seek injunctive relief without the requirement of posting
security) and the recovery of actual damages suffered by the Company as a
result of a breach of this Section 10 by the Executive. Notwithstanding the
foregoing, in no case shall any portion of the lump sum payment set forth in
Section 4(a)(i) or any Gross-Up Payment hereunder (or any other payments made
hereunder) be recoverable by the Parent or the Company (or subject to any
set-off, counterclaim or recoupment) in respect of damages resulting from a
breach of this Section 10.


                                       5
<PAGE>

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         7.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made within
                  five (5) business days after delivery of the Executive's
                  written requests for payment accompanied with evidence of fees
                  and expenses incurred. The Company's and Parent's obligation
                  with respect to a Gross-Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent


                                       6
<PAGE>

                  shall be final, and the Company and the Parent will not seek
                  to recover all or any part of such payment from the Executive,
                  or from whomsoever may be entitled thereto, for any reason
                  whatsoever.

         8.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's Severance Agreement with the Company dated
                  November 1, 1998 and that such agreement shall be terminated
                  as of the date of the consummation of the Offer.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         10.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         11.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same agreement.

                  Executive was receiving or entitled to receive immediately
                  prior to the Termination Date. If and to the extent that any
                  Medical Benefit described above in this Section 4(a)(ii)
                  cannot be provided under any applicable law or regulation or
                  under any policy, plan, program or arrangement of the Company,
                  then the Company will take all action necessary to ensure that
                  such Medical Benefit is provided through other means to the
                  Executive, his dependents and beneficiaries, as applicable.

         5.       The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

         6.       The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):


                                       2

10. NON-COMPETITION; CONFIDENTIALITY: (a) Executive agrees and acknowledges that
reasonable limits on his ability to engage in activities which are competitive
with the Company are warranted in order to protect the Company's trade secrets
and proprietary information and are warranted in order to protect the Company in
developing and maintaining its reputation, good will and status in the
marketplace. In that regard, during the 24 months following the Termination Date
(the "Continuation Period"), the Executive will not directly or indirectly, on
Executive's own behalf or in the service of or on behalf of any other individual
or entity, either as a proprietor, employee, agent, independent contractor,
consultant, director, officer, partner or stockholder (other than a stockholder
of a corporation listed on a national securities exchange or whose stock is
regularly traded in the over-the-counter market, provided that the Executive at
no time owns, directly or indirectly, in excess of 5% of the outstanding stock
of any class of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by the
Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by the
Company subsequent to the Effective Time and in which the Executive actively
participated, recognizing that the Company offers products and services globally
("Competitive Activities"), including, without limitation, (A) selling goods or
rendering services of the type (or similar to the type) sold or rendered by the
Company, whether by means of electronic, traditional or other form of commerce;
(B) soliciting any person or entity that is a current or prospective customer or
has been a customer, in each case, of the Company, while the Executive has been
employed by the Company (provided that it shall not be deemed a breach of this
Agreement if the Executive solicits such customers for goods or services
unrelated to the Competitive Activities) and (C) assisting any person in any way
to do, or attempt to do, anything prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior to
the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of the
Effective Time, and may engage in any activities or businesses for which the


                                       3
<PAGE>

Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of one year from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's lines
of businesses.

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by the
Company, whether in written, oral or other form. "Confidential Information"
shall mean information about the Company, and its clients and customers that is
not disclosed by the Company for financial reporting purposes and that was
learned by the Executive in the course of employment with the Company, including
(without limitation) any proprietary knowledge, product and service designs,
trade secrets, manuals, technical information and plans, contracts, systems,
procedures, databases, electronic files, disks and printouts, correspondence,
internal reports, personnel files, information about Company employees relating
to their education, experience, skills, abilities, compensation and benefits,
and inter-personal relationships with suppliers to and customers of Company,
sales and advertising material, business plans, marketing plans, financial data
(including without limitation the revenues, costs or profits associated with
services), customer and industry lists, customer information, customer lists
coupled with product or service pricing, customer contracts, supplier contacts
and other contact information, pricing policies, supplies, agents, risk
analyses, engineering information and computer screen designs and computer input
and output specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges that
such Confidential Information is specialized, unique in nature and of great
value to the Company, and that such information gives the Company a competitive
advantage. The Executive's obligations under this Section 10(c) shall survive
the termination of the Continuation Period.

                  (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of the
Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.


                                       4
<PAGE>

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any reasonable
action by, and will cooperate with, the Company to obtain an appropriate
protective order or other reliable assurance that confidential treatment will be
accorded the Confidential Information. If, failing the entry of a protective
order or the receipt of a waiver hereunder, the Executive is, in the opinion of
Executive's counsel, compelled by law to disclose a portion of the Confidential
Information, the Executive may disclose to the relevant tribunal without
liability hereunder that portion of the Confidential Information which counsel
advises the Executive he is legally required to disclose, and each of the
parties hereto agrees to exercise such party's best efforts to obtain assurance
that confidential treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowledges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.


                                       5
<PAGE>

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         7.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made within
                  five (5) business days after delivery of the Executive's
                  written requests for payment accompanied with evidence of fees
                  and expenses incurred. The Company's and Parent's obligation
                  with respect to a Gross-Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent


                                       6

                  shall be final, and the Company and the Parent will not seek
                  to recover all or any part of such payment from the Executive,
                  or from whomsoever may be entitled thereto, for any reason
                  whatsoever.

         8.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's Severance Agreement with the Company dated
                  November 15, 1999 and that such agreement shall be terminated
                  as of the date of the consummation of the Offer.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         10.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         11.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same Agreement.

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of

                  Executive was receiving or entitled to receive immediately

remain a director at those companies for which Executive is a director as of the

customer contracts, supplier contacts and other contact information, pricing
policies, supplies, agents, risk analyses, engineering information and computer
screen designs and computer input and output specifications, inclusive of any
pertinent documentation, techniques, processes, technical information and know
how. The Executive acknowledges that such Confidential Information is
specialized, unique in nature and of great value to the Company, and that such
information gives the Company a competitive advantage. The Executive's
obligations under this Section 10(c) shall survive the termina tion of the
Continuation Period.

                  (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of the
Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that


                                        4

the Company may seek an appropriate protective order or waiver of the
Executive's compliance with the provisions of this Section 10(c). The Executive
will not oppose any reasonable action by, and will cooperate with, the Company
to obtain an appropriate protective order or other reliable assurance that
confidential treatment will be accorded the Confidential Information. If,
failing the entry of a protective order or the receipt of a waiver hereunder,
the Executive is, in the opinion of Executive's counsel, compelled by law to
disclose a portion of the Confidential Information, the Executive may disclose
to the relevant tribunal without liability hereunder that portion of the
Confidential Information which counsel advises the Executive he is legally
required to disclose, and each of the parties hereto agrees to exercise such
party's best efforts to obtain assurance that confidential treatment will be
accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any term
or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or arbitration
panel making such determination shall have the power to reduce the scope,
duration or area or the term or provision, to delete specific words or phrases,
or to replace any invalid or unen forceable term or provision with a term or
provision that is a valid and enforceable term or provision, and this Section 10
shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive of
the provisions of this Section 10, the Company's remedies in respect of such
breach or threatened breach shall be limited to injunctive relief (and the
Executive acknowl edges that the Company may not have an adequate remedy at law
and may seek injunctive relief without the requirement of posting security) and
the recovery of actual damages suffered by the Company as a result of a breach
of this Section 10 by the Executive. Notwithstanding the foregoing, in no case
shall any portion of the lump sum payment set forth in Section 4(a)(i) or any
Gross Up Payment hereunder (or any other payments made hereunder) be recoverable
by the Parent or the Company (or subject to any set-off, counterclaim or
recoupment) in respect of damages resulting from a breach of this Section 10.

         (f) For the purposes of this Section 10, the term "Company" includes
not only Sterling Software, Inc., but also any subsidiary or affiliated
corporation of Sterling Software, Inc.

         7.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up Pay
                  ment. Such notification shall be given as soon as practicable
                  but no later than ten (10) business days after such party is
                  informed in writing of such a claim and such party shall
                  apprise the other party of the nature of such claim and the
                  date on which such claim is requested to be paid. The Parent
                  and the Company shall bear and pay directly all costs and
                  expenses (including legal fees and any interest and penal
                  ties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made
                  within five (5) business days after delivery of the
                  Executive's written requests for payment accompanied with
                  evidence of fees and expenses incurred. The Company's and
                  Parent's obligation with respect to a Gross-Up Payment and
                  reimbursement of related legal fees and expenses shall be
                  absolute and unconditional and shall not be affected by any
                  circumstances, including, without limitation, any setoff,
                  counterclaim, recoupment, defense or other right which the
                  Company or the Parent may have against the Executive or anyone
                  else. Except where provided herein to the contrary, all
                  amounts payable by the Company or the Parent hereunder shall
                  be paid without notice or demand. Each and every payment made
                  hereunder by the Company or the Parent shall be final, and the
                  Company and the Parent will not seek to recover all or any
                  part of such payment from the Executive, or from whomsoever
                  may be entitled thereto, for any reason whatsoever.

         8.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's Severance Agreement with the Company dated August
                  15, 1997 and that such agreement shall be terminated as of the
                  date of the consummation of the Offer.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         10.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         11.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same Agreement.

                                    FORM OF
                                  AMENDMENT TO
                      CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS AMENDMENT TO CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Amendment"),
dated as of February 14, 2000, by and among Sterling Software, Inc., a
Delaware corporation (the "Company"), Computer Associates International,
Inc., a Delaware corporation (the "Parent") and [                   ] (the
"Executive").

                                   WITNESSETH:

         WHEREAS, the Company and the Executive are parties to a Change in
Control Severance Agreement, dated as of [              ] (the "Agreement");
and

         WHEREAS, the Company, the Parent and the Executive desire to amend
the Agreement as set forth in this Amendment;

         NOW THEREFORE, the Company, the Parent and the Executive agree as
follows:

         1.       This Amendment shall be of no force and effect if the Offer
                  (as defined in the Agreement and Plan of Merger, dated as of
                  February 14, 2000, by and among the Parent, Silversmith
                  Acquisition Corp. and the Company) is not consummated.

         2.       The Agreement is hereby amended by replacing every occurrence
                  of the term "Employee Benefits" with the term "Medical
                  Benefits" and by the addition of a definition of Medical
                  Benefits as follows:

         (c)      "Medical Benefits" means the medical, dental, health,
                  hospital, disability and vision benefits provided under any
                  and all benefit policies, plans, programs or arrangements of
                  the Company that may now exist or any successor policies,
                  plans, programs or arrangements that may be adopted hereafter
                  by the Company in which the Executive is entitled to
                  participate or in which the Executive becomes entitled to
                  participate.


<PAGE>

         3.       Section 4(a)(i) is hereby amended to read as follows:

         (i)      pay to the Executive, within five (5) business days after the
                  Termination Date, a lump sum payment in an amount equal to
                  $[        ] as satisfaction in full for Executive's severance
                  pay and loss of certain perquisites and benefits that would
                  otherwise have been enjoyed by the Executive and for the
                  execution of the Executive's non-competition covenant in
                  Section 10 hereof. The parties agree that twenty-five (25)
                  percent of the lump sum payment shall be allocable to, and
                  deemed as consideration for, the Executive's non-competition
                  covenant in Section 10 hereof.(1)

         4.       Section 4(a)(ii) is hereby amended in its entirety to read as
                  follows:

         (ii)     for [  ] months following the Termination Date, arrange at its
                  sole expense, to provide the Executive with Medical Benefits
                  that are substantially similar to the better of (when
                  considered in the aggregate) (x) those Medical Benefits which
                  the Executive was receiving or entitled to receive immediately
                  prior to the Change in Control, or (y) those Medical Benefits
                  which the Executive was receiving or entitled to receive
                  immediately prior to the Termination Date. If and to the
                  extent that any Medical Benefit described above in this
                  Section 4(a)(ii) cannot be provided under any applicable law
                  or regulation or under any policy, plan, program or
                  arrangement of the Company, then the Company will take all
                  action necessary to ensure that such Medical Benefit is
                  provided through other means to the Executive, his dependents
                  and beneficiaries, as applicable.

         5.       The Company shall give the Executive the right to purchase
                  (such right to remain open until the expiration of thirty (30)
                  days from the Termination Date) at current book value, the
                  Company vehicle which was customarily provided to the
                  Executive as of immediately prior to the Executive's Date of
                  Termination.

         6.       The Agreement is hereby amended by the addition of a new
                  Section 10 (and amended as necessary in respect of required
                  renumbering):

- -------------------
(1) This sentence is not contained in certain agreements which do not contain
    a non-competition covenant.


                                       2
<PAGE>

10.   NON-COMPETITION; CONFIDENTIALITY(2): (a) Executive agrees and acknowledges
that reasonable limits on his ability to engage in activities which are
competitive with the Company are warranted in order to protect the Company's
trade secrets and proprietary information and are warranted in order to
protect the Company in developing and maintaining its reputation, good will
and status in the marketplace. In that regard, for twenty-four months
following the Termination Date (the "Continuation Period"), the Executive
will not directly or indirectly, on Executive's own behalf or in the service
of or on behalf of any other individual or entity, either as a proprietor,
employee, agent, independent contractor, consultant, director, officer,
partner or stockholder (other than a stockholder of a corporation listed on a
national securities exchange or whose stock is regularly traded in the
over-the-counter market, provided that the Executive at no time owns,
directly or indirectly, in excess of 5% of the outstanding stock of any class
of any such corporation):

         (i) participate or engage in any activities or business developing,
manufacturing, marketing or distributing any products or services offered by
the Company as of the Effective Time (as defined in the Agreement and Plan of
Merger, dated as of February 14, 2000, by and among the Parent, Silversmith
Acquisition Corp. and the Company), or any products or services offered by
the Company subsequent to the Effective Time and in which the Executive
actively participated, recognizing that the Company offers products and
services globally ("Competitive Activities"), including, without limitation,
(A) selling goods or rendering services of the type (or similar to the type)
sold or rendered by the Company, whether by means of electronic, traditional
or other form of commerce; (B) soliciting any person or entity that is a
current or prospective customer or has been a customer, in each case, of the
Company, while the Executive has been employed by the Company (provided that
it shall not be deemed a breach of this Agreement if the Executive solicits
such customers for goods or services unrelated to the Competitive Activities)
and (C) assisting any person in any way to do, or attempt to do, anything
prohibited by clauses (A) or (B) above; or

         (ii) solicit (other than pursuant to general, non-targeted
advertisements) any employee of the Company, who was an employee at or prior
to the Effective Time, to leave the employment of the Company.

         (b) Notwithstanding anything to the contrary herein, Executive may
remain a director at those companies for which Executive is a director as of
the Effective Time, and may engage in any activities or businesses for which
the

- -------------------
(2) Not all agreements contain a non-competition covenant.



                                       3

Company has given permission in writing, which shall not be unreasonably
withheld (or delayed) following the expiration of [      ] from the date the
Offer is consummated, provided Executive's engaging in such activities or
business would not have a material adverse impact on any of the Company's
lines of businesses.(3)

         (c) (i) The Executive shall not, without the written consent of the
Company, disclose to any other person or use, whether directly or indirectly,
any Confidential Information (as hereinafter defined) relating to or used by
the Company, whether in written, oral or other form. "Confidential
Information" shall mean information about the Company, and its clients and
customers that is not disclosed by the Company for financial reporting
purposes and that was learned by the Executive in the course of employment
with the Company, including (without limitation) any proprietary knowledge,
product and service designs, trade secrets, manuals, technical information
and plans, contracts, systems, procedures, databases, electronic files, disks
and printouts, correspondence, internal reports, personnel files, information
about Company employees relating to their education, experience, skills,
abilities, compensation and benefits, and inter-personal relationships with
suppliers to and customers of Company, sales and advertising material,
business plans, marketing plans, financial data (including without limitation
the revenues, costs or profits associated with services), customer and
industry lists, customer information, customer lists coupled with product or
service pricing, customer contracts, supplier contacts and other contact
information, pricing policies, supplies, agents, risk analyses, engineering
information and computer screen designs and computer input and output
specifications, inclusive of any pertinent documentation, techniques,
processes, technical information and know how. The Executive acknowledges
that such Confidential Information is specialized, unique in nature and of
great value to the Company, and that such information gives the Company a
competitive advantage. The Executive's obligations under this Section 10(c)
shall survive the termination of the Continuation Period.

                  (ii) Confidential Information does not include information
which (A) is or becomes part of the public domain other than as a result of
the Executive's disclosure; or (B) becomes available to the Executive on a
non-confidential basis from a source other than the Company, provided that
source is not bound with respect to that information by a confidentiality
agreement with the Company or otherwise prohibited from transmitting that
information by a contractual, legal or other obligation.

- -------------------
(3) The Assistant General Counsel's amendment provides that the Assistant
    General Counsel will not be in breach of the non-competition covenant
    if the Assistant General Counsel renders legal services as outside
    counsel.

<PAGE>

                  (iii) If the Executive is requested or (in the opinion of
Executive's counsel) required by law or judicial order to disclose any
Confidential Information, the Executive shall provide the Company with prompt
notice of any such request or requirement so that the Company may seek an
appropriate protective order or waiver of the Executive's compliance with the
provisions of this Section 10(c). The Executive will not oppose any
reasonable action by, and will cooperate with, the Company to obtain an
appropriate protective order or other reliable assurance that confidential
treatment will be accorded the Confidential Information. If, failing the
entry of a protective order or the receipt of a waiver hereunder, the
Executive is, in the opinion of Executive's counsel, compelled by law to
disclose a portion of the Confidential Information, the Executive may
disclose to the relevant tribunal without liability hereunder that portion of
the Confidential Information which counsel advises the Executive he is
legally required to disclose, and each of the parties hereto agrees to
exercise such party's best efforts to obtain assurance that confidential
treatment will be accorded such Confidential Information.

         (d) If an award by a court or arbitration panel declares that any
term or provision of this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable, the parties agree that the court or
arbitration panel making such determination shall have the power to reduce
the scope, duration or area or the term or provision, to delete specific
words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is a valid and enforceable term or
provision, and this Section 10 shall be enforceable as so modified.

         (e) In the event of a breach or threatened breach by the Executive
of the provisions of this Section 10, the Company's remedies in respect of
such breach or threatened breach shall be limited to injunctive relief (and
the Executive acknowledges that the Company may not have an adequate remedy
at law and may seek injunctive relief without the requirement of posting
security) and the recovery of actual damages suffered by the Company as a
result of a breach of this Section 10 by the Executive. Notwithstanding the
foregoing, in no case shall any portion of the lump sum payment set forth in
Section 4(a)(i) or any Gross Up Payment hereunder (or any other payments made
hereunder) be recoverable by the Parent or the Company (or subject to any
set-off, counterclaim or recoupment) in respect of damages resulting from a
breach of this Section 10.

         (f)      For the purposes of this Section 10, the term "Company"
                  includes not only Sterling Software, Inc., but also any
                  subsidiary or affiliated corporation of Sterling Software,
                  Inc.

         7.       Parent shall guarantee the Company's obligations pursuant to
                  the Agreement, including without limitation, Sections 5 and 7
                  thereof. The Parent and the Company hereby acknowledge that
                  the obligations set forth in such Sections will survive any
                  termination or expiration of this Agreement or termination of
                  Executive's employment for any reason. Each party will notify
                  the other in writing of any claim by the Internal Revenue
                  Service or any other taxing authority that, if successful,
                  would require the payment by the Company of a Gross-Up
                  Payment. Such notification shall be given as soon as
                  practicable but no later than ten (10) business days after
                  such party is informed in writing of such a claim and such
                  party shall apprise the other party of the nature of such
                  claim and the date on which such claim is requested to be
                  paid. The Parent and the Company shall bear and pay directly
                  all costs and expenses (including legal fees and any interest
                  and penalties) incurred in connection with any such claim or
                  proceeding, and shall indemnify and hold the Executive
                  harmless, on an after-tax basis, as provided in Section 5(a),
                  for any Excise Tax or income tax (including interest and
                  penalties with respect thereto) imposed as a result of such
                  representation and payment of costs and expenses. The Company
                  and the Parent also shall pay to the Executive all legal fees
                  and expenses incurred by the Executive in connection with any
                  tax audit or proceeding to the extent attributable to the
                  application of section 4999 of the Code to any payment or
                  benefit provided hereunder. Such payments shall be made within
                  five (5) business days after delivery of the Executive's
                  written requests for payment accompanied with evidence of fees
                  and expenses incurred. The Company's and Parent's obligation
                  with respect to a Gross-Up Payment and reimbursement of
                  related legal fees and expenses shall be absolute and
                  unconditional and shall not be affected by any circumstances,
                  including, without limitation, any setoff, counterclaim,
                  recoupment, defense or other right which the Company or the
                  Parent may have against the Executive or anyone else. Except
                  where provided herein to the contrary, all amounts payable by
                  the Company or the Parent hereunder shall be paid without
                  notice or demand. Each and every payment made hereunder by the
                  Company or the Parent


                                       6

                  shall be final, and the Company and the Parent will not seek
                  to recover all or any part of such payment from the Executive,
                  or from whomsoever may be entitled thereto, for any reason
                  whatsoever.

         8.       The Executive agrees as consideration for the Company's and
                  the Parent's entry into this Amendment that, effective upon
                  consummation of the Offer, the Executive shall be deemed to
                  have waived all rights the Executive may have pursuant to the
                  Executive's Severance Agreement with the Company dated
                  [              ] and that such agreement shall be terminated
                  as of the date of the consummation of the Offer.

         9.       Except as amended hereby, all other provisions of the
                  Agreement shall remain in full force and effect.

         10.      The validity, interpretation, construction and performance of
                  this Amendment will be governed by and construed in accordance
                  with the substantive laws of Delaware, without giving effect
                  to the conflict of laws principles of such State.

         11.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed to be an original but all of
                  which together will constitute one and the same agreement.

                                AMENDMENT TO THE
                             STERLING SOFTWARE, INC.
                          EMPLOYEE HEALTH BENEFIT PLAN

                       (Effective as of December 31, 1999)


         Sterling Software, Inc., a Delaware corporation, adopts the following
amendment to the Sterling Software, Inc. Employee Health Benefit Plan (the
"Plan"):

         1. Section 3.01(a) of the Plan is hereby amended, effective as of
December 31, 1999, to read in its entirety as follows:

                  3.01 ELIGIBILITY. A person meeting the requirements of either
         paragraph (a) or paragraph (b) below shall be eligible to receive
         Benefits under the Plan. Any person meeting such eligibility
         requirements shall hereinafter be referred to as a "Participant."

                           (a) EMPLOYEES. Any employee of Employer shall be
         eligible to receive Benefits under the Plan if he or she meets the
         eligibility requirements established from time to time by Employer with
         respect to the receipt of health benefits, including eligibility to
         participate in any health maintenance organization participation in
         which is made available by Employer, which requirements shall not be
         discriminatory in favor of highly-compensated employees. The
         requirements for eligibility to receive Benefits may vary among the
         Company and Affiliates and between separate, identifiable divisions of
         the Company or an Affiliate, as long as such variations do not
         constitute or result in discrimination violating any provision of the
         Code, ERISA, or applicable regulations. Notwithstanding the foregoing,
         a person who is treated by Employer as an independent contractor
         performing services for Employer, and not as a common law employee or
         former common law employee of Employer, shall not be eligible to
         receive benefits under the Plan, regardless of whether such person
         could be deemed under any applicable regulatory regime as a common law
         employee or former common law employee of Employer or any Affiliate.

         2. The Plan is hereby amended, effective as of December 31, 1999, by
adding thereto the following new Section 6.03, to read in its entirety as
follows:

                  6.03 CHANGE IN CONTROL. Notwithstanding anything herein to the
         contrary (including, without limitation, the second sentence of Section
         6.02 of the Plan), from and after the date of a Change in Control (as
         that term is defined below), the Plan may not be amended or terminated,
         with respect to any person
<PAGE>

         who is a Participant in the Plan as of the date of such Change in
         Control by virtue of Section 3.01(b) of the Plan and either receiving
         or eligible to receive retiree medical benefits under Section 4.01(b)
         of the Plan, without the written consent of such Participant. As used
         herein, the term "Change in Control" shall mean the occurrence of any
         of the following events:

                    (i) The Company is merged, consolidated or reorganized into
              or with another corporation or other legal person, and as a result
              of such merger, consolidation or reorganization less than
              two-thirds of the combined voting power of the then-outstanding
              securities entitled to vote generally in the election of directors
              ("Voting Stock") of such corporation or person immediately after
              such transaction are held in the aggregate by the holders of
              Voting Stock of the Company immediately prior to such transaction;

                    (ii) The Company sells or otherwise transfers all or
              substantially all of its assets to another corporation or other
              legal person, and less than two-thirds of the combined voting
              power of the then-outstanding Voting Stock of such corporation or
              person is held in the aggregate by the holders of Voting Stock of
              the Company immediately prior to such sale or transfer;

                    (iii) There is a report filed on Schedule 13D or Schedule
              14D-1 (or any successor schedule, form or report), each as
              promulgated pursuant to the Securities Exchange Act of 1934, as
              amended (the "Exchange Act"), disclosing that any person (as the
              term "person" is used in Section 13(d)(3) or Section 14(d)(2) of
              the Exchange Act) has become the beneficial owner (as the term
              "beneficial owner" is defined under Rule 13d-3 or any successor
              rule or regulation promulgated under the Exchange Act) of
              securities representing 20% or more of the combined voting power
              of the then-outstanding Voting Stock of the Company;

                    (iv) The Company files a report or proxy statement with the
              Securities and Exchange Commission pursuant to the Exchange Act
              disclosing in response to Form 8-K or Schedule 14A (or any
              successor schedule, form or report or item therein) that a change
              in control of the Company has occurred or will occur in the future
              pursuant to any then-existing contract or transaction; or

                    (v) If, at any time during any period of two consecutive
              years, individuals who at the beginning of any such period
              constitute the directors of the Company cease for any reason to
              constitute at least a majority thereof; provided, however, that
              for purposes of this clause (v) each director (other than a
              director whose initial assumption of office is in connection with
              an actual or threatened election contest) who is first elected, or
              first nominated for election by the Company's stockholders, by a
              vote of at least two-thirds of the directors of the Company (or a
              committee thereof) then still in office who were directors of the
              Company at the beginning of any such period will be deemed to have
              been a director of the Company at the beginning of such period.


                                       2
<PAGE>

         Notwithstanding the foregoing provisions of clauses (iii) or (iv),
         unless otherwise determined in a specific case by majority vote of the
         board of directors of the Company, a "Change in Control" shall not be
         deemed to have occurred for purposes of clause (iii) or (iv) solely
         because (A) the Company, (B) an entity in which the Company directly or
         indirectly beneficially owns 50% or more of the outstanding Voting
         Stock (a "Subsidiary"), or (C) any Company-sponsored employee stock
         ownership plan or any other employee benefit plan of the Company or any
         Subsidiary either files or becomes obligated to file a report or a
         proxy statement under or in response to Schedule 13D, Schedule 14D-1,
         Form 8-K or Schedule 14A (or any successor schedule, form or report or
         item therein) under the Exchange Act disclosing beneficial ownership by
         it of shares of Voting Stock of the Company, whether in excess of 20%
         or otherwise, or because the Company reports that a change in control
         of the Company has occurred or will occur in the future by reason of
         such beneficial ownership or any increase or decrease thereof.


                  Executed at Dallas, Texas as of the 31st day of December,
1999.

                           TO STERLING SOFTWARE, INC.
                   AMENDED AND RESTATED 1996 STOCK OPTION PLAN


         This Amendment (herein so called) to the Sterling Software, Inc.
Amended and Restated 1996 Stock Option Plan is adopted effective as of January
31, 2000:

                                    RECITALS:
         A. Sterling Software, Inc., a Delaware corporation (the "Company"),
established the Sterling Software, Inc. 1996 Stock Option Plan, effective as of
April 22, 1996 (the "Original Plan"). The Original Plan was approved by the
Company's stockholders on May 29, 1996, was amended and restated effective as of
September 4, 1996, and was subsequently amended and restated as of February 12,
1999 (as so amended and restated, the "Plan").

         B. Pursuant to and in accordance with Paragraph 9 of the Plan, the 1996
Stock Option Committee of the Company's Board of Directors has authorized and
approved the further amendment of the Plan, as hereinafter set forth.

                                   AMENDMENT:

         1. Paragraph 6 of the Plan is hereby amended to read in its entirety as
follows:

                  6. ADJUSTMENTS. In the event of any change in the capital
         structure or business of the Company by reason of any stock dividend or
         extraordinary dividend, stock split or reverse stock split,
         recapitalization, reorganization, merger, consolidation, split-up,
         combination or exchange of shares, non-cash distributions with respect
         to its outstanding Common Stock or capital stock other than Common
         Stock, reclassification of the Company's capital stock, any sale or
         transfer of all or part of the Company's assets or business, or any
         similar change affecting the Company's capital structure or business or
         the capital structure of any business of any Subsidiary or a change in
         control of the Company, as determined by the Stock Option Committee,
         the Special Stock Option Committee or the Board, and as such committee
         or the Board determines in good faith that an adjustment is necessary
         or appropriate under the Plan to prevent substantial dilution or
         enlargement of the rights granted to, or available for, Participants
         under the Plan or as otherwise necessary to reflect the change, then
         the aggregate number and kind of shares of Common Stock which may be
         issued under Paragraph 3 of the Plan, the number and kind of shares
         (including shares of another issuer) subject to outstanding Stock
         Options under the Plan and the Option Price thereof shall be
         appropriately adjusted consistent with such change in such manner as
         such committee or the Board may deem equitable to prevent substantial
         dilution or enlargement of the rights granted to, or available for,

<PAGE>

         Participants under the Plan or as otherwise necessary to reflect the
         change, and any such adjustment determined by such committee or the
         Board in good faith shall be binding and conclusive on the Company and
         all Participants and their respective heirs, executors, administrators,
         successors and assigns. In connection with any event described in this
         paragraph, such committee or the Board may provide, in its sole
         discretion, for the cancellation of any outstanding Stock Options and
         payment in cash or other property in exchange therefor. Notice of any
         adjustment shall be given by such committee or the Board to each
         Participant whose Stock Option has been adjusted and such adjustment
         (whether or not such notice is given) shall be effective and binding
         for all purposes of this Plan. Any fractional shares resulting from the
         foregoing adjustments will be eliminated. In the event the Stock Option
         Committee and the Special Stock Option Committee shall disagree (or
         either or both shall disagree with the Board) with respect to the
         foregoing adjustments, the Board's determination will be final and
         conclusive.

         2. Capitalized terms used and not otherwise defined in this Amendment
shall have the respective meanings ascribed to such terms in the Plan.

         3. In all other respects, the Plan, as amended hereby, is ratified,
confirmed and approved in all respects.


         IN WITNESS WHEREOF, this Amendment has been executed at Dallas, Texas
as of the 31st day of January, 2000.

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as
of November 15, 1999, by and between Sterling Software, Inc., a Delaware
corporation (the "Company"), and R. Logan Wray (the "Executive").

                                   WITNESSETH:

         WHEREAS, the Executive is a senior executive of the Company and is
expected to make major contributions to the profitability, growth and financial
strength of the Company;

         WHEREAS, the Company recognizes that, as is the case of most companies,
the possibility of a Change in Control (as hereinafter defined) exists;

         WHEREAS, the Company desires to assure itself of both present and
future continuity of management and desires to establish certain minimum
severance benefits for certain of its senior executives, including the
Executive, applicable in the event of a Change in Control; and

         WHEREAS, the Company desires to provide additional inducement for the
Executive to remain in the ongoing employ of the Company;

         NOW, THEREFORE, the Company and the Executive agree as follows:

         1. CERTAIN DEFINED TERMS: In addition to terms defined elsewhere
herein, the following terms have the following meanings when used in this
Agreement with initial capital letters:

                  (a) "Base Pay" means the Executive's annual fixed or base
         compensation, as may be determined from time to time by the Company,
         whether acting through its Board of Directors (the "Board") or a
         committee thereof, its President and CEO or otherwise.

                  (b) "Change in Control" means the occurrence during the Term
         of any of the following events:

                              (i) The Company is merged, consolidated or
                  reorganized into or with another corporation or other legal
                  person, and as a result of such merger, consolidation or
                  reorganization less than two-thirds of the combined voting
                  power of the then-outstanding securities entitled to vote
                  generally in the election of directors ("Voting Stock") of
                  such corporation or person immediately after such transaction
                  are held in the aggregate by the holders of Voting Stock of
                  the Company immediately prior to such transaction;

                              (ii) The Company sells or otherwise transfers all
                  or substantially all of its assets to another corporation or
                  other legal person, and less than two-thirds of the combined
                  voting power of the then-outstanding Voting Stock of such
                  corporation or person is held in the aggregate by the holders
                  of Voting Stock of the Company immediately prior to such sale
                  or transfer;
<PAGE>

                              (iii) There is a report filed on Schedule 13D or
                  Schedule 14D-1 (or any successor schedule, form or report),
                  each as promulgated pursuant to the Securities Exchange Act of
                  1934, as amended (the "Exchange Act"), disclosing that any
                  person (as the term "person" is used in Section 13(d)(3) or
                  Section 14(d)(2) of the Exchange Act) has become the
                  beneficial owner (as the term "beneficial owner" is defined
                  under Rule 13d-3 or any successor rule or regulation
                  promulgated under the Exchange Act) of securities representing
                  20% or more of the combined voting power of the
                  then-outstanding Voting Stock of the Company;

                              (iv) The Company files a report or proxy statement
                  with the Securities and Exchange Commission pursuant to the
                  Exchange Act disclosing in response to Form 8-K or Schedule
                  14A (or any successor schedule, form or report or item
                  therein) that a change in control of the Company has occurred
                  or will occur in the future pursuant to any then-existing
                  contract or transaction; or

                              (v) If, at any time during any period of two
                  consecutive years, individuals who at the beginning of any
                  such period constitute the Directors of the Company cease for
                  any reason to constitute at least a majority thereof;
                  provided, however, that for purposes of this clause (v) each
                  Director (other than a Director whose initial assumption of
                  office is in connection with an actual or threatened election
                  contest) who is first elected, or first nominated for election
                  by the Company's stockholders, by a vote of at least
                  two-thirds of the Directors of the Company (or a committee
                  thereof) then still in office who were Directors of the
                  Company at the beginning of any such period will be deemed to
                  have been a Director of the Company at the beginning of such
                  period.

         Notwithstanding the foregoing provisions of Sections 1(b)(iii) or
         1(b)(iv), unless otherwise determined in a specific case by majority
         vote of the Board, a "Change in Control" shall not be deemed to have
         occurred for purposes of Section 1(b)(iii) or 1(b)(iv) solely because
         (A) the Company, (B) an entity in which the Company directly or
         indirectly beneficially owns 50% or more of the outstanding Voting
         Stock (a "Subsidiary"), or (C) any Company-sponsored employee stock
         ownership plan or any other employee benefit plan of the Company or any
         Subsidiary either files or becomes obligated to file a report or a
         proxy statement under or in response to Schedule 13D, Schedule 14D-1,
         Form 8-K or Schedule 14A (or any successor schedule, form or report or
         item therein) under the Exchange Act disclosing beneficial ownership by
         it of shares of Voting Stock of the Company, whether in excess of 20%
         or otherwise, or because the Company reports that a change in control
         of the Company has occurred or will occur in the future by reason of
         such beneficial ownership or any increase or decrease thereof.

                  (c) "Employee Benefits" means the perquisites, benefits and
         service credit for perquisites or benefits as provided under any and
         all employee perquisite or benefit policies, plans, programs or
         arrangements in which Executive is entitled to participate, including
         without limitation any stock option, stock purchase, stock
         appreciation, savings, pension, 401(k), employee stock ownership
         (ESOP), employee stock purchase (ESPP), supplemental executive
         retirement, or other retirement income or welfare benefit, deferred
         compensation, incentive compensation, group or other life, health,
         medical/hospital or other insurance (whether funded by actual insurance
         or self-insured by the Company), disability, salary


                                       2
<PAGE>

         continuation, expense reimbursement, executive automobile, tax and
         financial planning, club memberships, incentive travel, tax
         reimbursement and other employee benefit policies, plans, programs or
         arrangements that may now exist or any successor policies, plans,
         programs or arrangements that may be adopted hereafter by the Company.

                  (d) "Incentive Pay" means the aggregate annual bonus,
         incentive or other payments of cash compensation, in addition to Base
         Pay, made or authorized or contemplated to be made in regard to
         services rendered by the Executive in any fiscal year pursuant to any
         bonus, incentive compensation, profit-sharing, performance,
         discretionary pay or similar agreement, policy, plan, program or
         arrangement (whether or not funded) of the Company or any successor
         thereto.

                  (e) "Severance Period" means the period of time commencing on
         the date of the first occurrence of a Change in Control and continuing
         until the earliest of (i) the fourth anniversary of the occurrence of
         the Change in Control, or (ii) the Executive's death; provided,
         however, that commencing on each anniversary of the Change in Control,
         the Severance Period will automatically be extended for an additional
         year unless, not later than 90 calendar days prior to such anniversary
         date, either the Company or the Executive shall have given written
         notice to the other that the Severance Period is not to be so extended.

                  (f) "Term" means the period commencing as of the date first
         set forth above and expiring as of the later of (i) the close of
         business on December 31, 2004, or (ii) the expiration of the Severance
         Period; provided, however, that (A) commencing on January 1, 2001 and
         each January 1 thereafter, the Term of this Agreement will
         automatically be extended for an additional year unless, not later than
         September 30 of the immediately preceding year, the Company or the
         Executive shall have given written notice that it or the Executive, as
         the case may be, does not wish to have the Term extended and (B)
         subject to the last sentence of Section 8, if, prior to a Change in
         Control, the Executive ceases for any reason to be an employee of the
         Company or any Subsidiary, thereupon without further action the Term
         shall be deemed to have expired and this Agreement will immediately
         terminate and be of no further effect.

         2. OPERATION OF AGREEMENT: This Agreement will be effective and binding
immediately upon its execution, but, anything in this Agreement to the contrary
notwithstanding, this Agreement will not be operative unless and until a Change
in Control occurs. Upon the occurrence of a Change in Control at any time during
the Term, without further action, this Agreement shall become immediately
operative.

         3. TERMINATION FOLLOWING A CHANGE IN CONTROL: (a) In the event of the
occurrence of a Change in Control, the Executive's employment may be terminated
by the Company during the Severance Period. If, during the Severance Period, the
Executive's employment is terminated by the Company or any Subsidiary other than
as a result of the Executive's death, the Executive will be entitled to the
compensation and benefits provided by Section 4 hereof.

                  (b) In the event of the occurrence of a Change in Control, the
Executive may terminate his or her employment with the Company during the
Severance Period, with the right to the compensation and benefits as provided in
Section 4, upon the occurrence of one or more of the


                                       3
<PAGE>

following events (regardless of whether any other reason for such termination
exists or has occurred, including without limitation, other employment):

                     (i) Failure to elect or reelect or otherwise to maintain
         the Executive in the office of the Company which the Executive held
         immediately prior to a Change in Control, or the removal of the
         Executive as a Director of the Company (or any successor thereto) if
         the Executive shall have been a Director of the Company immediately
         prior to the Change in Control;

                     (ii) (A) A significant adverse change in the nature or
         scope of the authorities, powers, functions, responsibilities or duties
         attached to the position which the Executive held immediately prior to
         the Change in Control, (B) a reduction in the aggregate amount of the
         Executive's Base Pay or Incentive Pay as in effect for the Executive
         immediately prior to the occurrence of a Change in Control or such
         higher amount of Base Pay or Incentive Pay as may thereafter be
         determined by the Company, whether acting through the Board or a
         committee thereof, its President and CEO or otherwise, or (C) the
         termination or denial of the Executive's rights to Employee Benefits or
         a reduction in the scope or value thereof, any of which is not remedied
         by the Company within 10 calendar days after receipt by the Company of
         written notice from the Executive of such change, reduction,
         termination or denial, as the case may be;

                     (iii) A determination by the Executive (which determination
         will be conclusive and binding upon the parties hereto provided it has
         been made in good faith and in all events will be presumed to have been
         made in good faith unless otherwise shown by the Company by clear and
         convincing evidence) that a change in circumstances has occurred
         following a Change in Control, including, without limitation, a change
         in the scope of the business or other activities for which the
         Executive was responsible immediately prior to the Change in Control,
         which has rendered the Executive substantially unable to carry out, has
         substantially hindered Executive's performance of, or has caused
         Executive to suffer a substantial reduction in, any of the authorities,
         powers, functions, responsibilities or duties attached to the position
         held by the Executive immediately prior to the Change in Control, which
         situation is not remedied within 10 calendar days after written notice
         to the Company from the Executive of such determination. For the
         avoidance of doubt, but without limiting the generality of the
         foregoing, if the Company or its successor following a Change in
         Control ceases to be an independent, publicly held, New York Stock
         Exchange-listed company, the Executive may in good faith determine that
         such circumstance, in and of itself, constitutes a substantial
         reduction in his authorities, powers, functions, responsibilities or
         duties;

                     (iv) The liquidation, dissolution, merger, consolidation or
         reorganization of the Company or transfer of all or substantially all
         of its business and/or assets, unless the successor or successors (by
         liquidation, merger, consolidation, reorganization, transfer or
         otherwise) to which all or substantially all of its business and/or
         assets have been transferred (directly or by operation of law) assumed
         all duties and obligations of the Company under this Agreement pursuant
         to Section 10(a);

                     (v) The Company relocates its principal executive offices,
         or requires the Executive to have his principal location of work
         changed, to any location which is in excess


                                       4
<PAGE>

         of 25 miles from the location thereof immediately prior to the Change
         in Control, or requires the Executive to travel away from his office in
         the course of discharging his responsibilities or duties hereunder at
         least 20% more (in terms of aggregate days in any calendar year or in
         any calendar quarter when annualized for purposes of comparison to any
         prior year) than was required of Executive in any of the three full
         years immediately prior to the Change in Control without, in either
         case, his prior written consent; or

                     (vi) Without limiting the generality or effect of the
         foregoing, any material breach of this Agreement by the Company or any
         successor thereto.

                  (c) A termination by the Company pursuant to Section 3(a) or
by the Executive pursuant to Section 3(b) will not affect any rights which the
Executive may have pursuant to any agreement, policy, plan, program or
arrangement of the Company providing Employee Benefits, which rights shall be
governed by the terms thereof. The Company and the Executive are parties to a
Severance Agreement, dated as of November 15, 1999 (as such agreement may be
amended from time to time, the "Severance Agreement"). Notwithstanding anything
contained in this Agreement to the contrary, in the event the Executive's
employment with the Company is terminated under circumstances in which the
Executive would otherwise be entitled to receive payments and benefits under
both this Agreement and the Severance Agreement, the Executive shall have the
right to elect to receive payments and benefits under either this Agreement or
the Severance Agreement, but not both (except that the Executive may in all
events receive all payments and benefits to which he or she is entitled under
the Severance Agreement during the period between the Termination Date and the
Election Date (as such terms are defined below)). Within five business days
following the date of the termination of the Executive's employment with the
Company under the circumstances described in the preceding sentence (the
"Termination Date"), which shall be the effective date of such termination if
the termination is pursuant to Section 3(a) or such other date that may be
specified by the Executive if the termination is pursuant to Section 3(b), the
Company shall provide the Executive, in writing, a reasonably detailed
determination of the payments and other benefits under each of this Agreement
and the Severance Agreement. Executive shall make the election provided for in
this Section 3(c) by providing the Company written notice thereof within 30 days
after the Executive's receipt of the written determination referred to in the
preceding sentence; provided, however, that if such election is not so made
within such 30-day period, the Executive shall be irrevocably deemed to have
elected to receive payments and benefits under this Agreement (the date on which
such election is so made or deemed to have been made being the "Election Date").

         4. SEVERANCE COMPENSATION AND BENEFITS: (a) If, following the
occurrence of a Change in Control, the Company terminates the Executive's
employment during the Severance Period pursuant to Section 3(a) (other than as a
result of the Executive's death), or if the Executive terminates his employment
during the Severance Period pursuant to Section 3(b), the Company will:

                     (i) pay to the Executive, within five business days after
         the Termination Date (or, in the event that the circumstance described
         in Section 3(c) hereof is applicable, within five business days after
         the Election Date), a lump sum payment (the "Severance Payment") in an
         amount equal to four times the sum of (A) Base Pay (the aggregate
         amount and the components of which shall be determined based on the
         highest rate in effect for any period prior to the Termination Date),
         plus (B) Incentive Pay in an amount


                                       5
<PAGE>

         equal to the higher of (i) the highest annual amount of Incentive Pay
         paid to or earned by the Executive with respect to any fiscal year
         during the three fiscal years immediately preceding the fiscal year in
         which the Termination Date occurs, and (ii) 100% of the Incentive Pay
         amount payable upon the attainment of 100% of the objective(s) and 100%
         of the targeted or planned amount(s) specified in or pursuant to the
         applicable agreement, policy, plan, program or arrangement, whether or
         not attained as of such Termination Date, for such Executive for the
         fiscal year in which the Termination Date occurs; provided however,
         that the Severance Payment shall be reduced by the aggregate amount of
         all cash payments, if any, previously received by the Executive
         pursuant to the Severance Agreement prior to the Election Date.

                     (ii) (A) for 48 months following the Termination Date (the
         "Continuation Period"), arrange at its sole expense, to provide the
         Executive with Employee Benefits that are substantially similar to the
         better of (when considered in the aggregate) (X) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Change in Control, or (Y) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Termination Date, and (B) such Continuation
         Period will be considered service with the Company for the purpose of
         determining service credits under or in respect of any Employee
         Benefits applicable to the Executive, his dependents or his
         beneficiaries; provided that for purposes of this Section 4(a)(ii),
         Employee Benefits shall not include any Incentive Pay and nothing in
         this Section 4(a) shall be construed to require the Company to make any
         new grants of stock options to the Executive. If and to the extent that
         any Employee Benefit described in subsection (A) or (B) of this Section
         4(a)(ii) cannot be paid or provided under any applicable law or
         regulation or under the terms of any policy, plan, program or
         arrangement of the Company, then the Company will take all action
         necessary to ensure that such Employee Benefit is provided through
         other means to the Executive, his dependents and beneficiaries, as
         applicable, or the Company shall timely pay to the Executive a lump sum
         amount in cash equal to the fair market value of such foregone Employee
         Benefit. Notwithstanding the immediately preceding sentence, the
         Company shall make any payment that may be necessary to ensure that the
         Executive's after tax position with respect to any Employee Benefits
         received pursuant to this Section 4(a)(ii) is not worse than the
         Executive's after-tax position in the event such Employee Benefits had
         been provided to the Executive while he was employed by the Company.

                     (iii) for the life of the Executive and his or her spouse,
         to (A) arrange to provide (A) the Executive and his or her spouse with
         retiree health benefits substantially identical to the "Benefits" that
         would have been provided to the Executive and his or her spouse under
         the Company's Employee Health Benefit Plan, as amended as of December
         31, 1999 (the "Health Plan"), if the Executive had met the requirements
         of Section 4.01(b)(iii) of the Health Plan as of the "Retiree Record
         Date", and (B) the Executive with the right and opportunity to elect to
         receive health benefits for his or her eligible dependents
         substantially identical to the "Benefits" offered under Section
         4.01(b)(iv) of the Health Plan. The terms "Benefits" and "Retiree
         Record Date" shall have the respective meanings ascribed to such terms
         in the Health Plan.

                  (b) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided


                                       6

hereunder on a timely basis, the Company will pay interest on the amount or
value thereof at an annualized rate of interest equal to the so-called composite
"prime rate" as quoted from time to time during the relevant period in the
Southwest Edition of THE WALL STREET JOURNAL. Such interest will be payable as
it accrues on demand. Any change in such prime rate will be effective on and as
of the date of such change.

                  (c) Notwithstanding any other provision of this Agreement to
the contrary, the parties' respective rights and obligations under this Section
4 and under Sections 5 and 7 will survive any termination or expiration of this
Agreement or the termination of the Executive's employment following a Change in
Control for any reason whatsoever.

         5. CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY: (a) Anything in this
Agreement to the contrary notwithstanding, in the event that this Agreement
shall become operative and it shall be determined (as hereafter provided) that
all or any portion of any payment or distribution by the Company or any of its
affiliates to or for the benefit of the Executive pursuant to the terms of this
Agreement or otherwise, including under any stock option or other agreement,
plan, policy, program or arrangement (a "Payment"), would be subject to the
excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code") (or any successor provision thereto), by reason of being
considered "contingent on a change in ownership or control" of the Company,
within the meaning of Section 280G of the Code (or any successor provision
thereto), or to any similar tax imposed by state or local law, or any interest
or penalties with respect to such tax (such tax or taxes, together with any such
interest and penalties, being hereafter collectively referred to as the "Excise
Tax"), then the Executive shall be entitled to receive an additional payment or
payments (collectively, a "Gross-Up Payment"); provided, however, that no
Gross-Up Payment shall be made with respect to the Excise Tax, if any,
attributable to (i) any incentive stock option, as defined by Section 422 of the
Code ("ISO") granted prior to the execution of this Agreement, or (ii) any stock
appreciation or similar right, whether or not limited, granted in tandem with an
ISO described in clause (i). The Gross-Up Payment shall be in an amount such
that, after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including any Excise Tax imposed
upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payment.

                  (b) Subject to the provisions of Section 5(f), all
determinations required to be made under this Section 5, including whether an
Excise Tax is payable by the Executive and the amount of such Excise Tax and
whether a Gross-Up Payment is required to be paid by the Company to the
Executive and the amount of such Gross-Up Payment, if any, shall be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive in his sole discretion. The Executive shall direct the Accounting Firm
to submit its determination and detailed supporting calculations to both the
Company and the Executive within 30 calendar days after the Termination Date, if
applicable, and any such other time or times as may be requested by the Company
or the Executive. If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Gross-Up Payment to
the Executive within five business days after receipt of such determination and
calculations with respect to any Gross-Up Payment to the Executive. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall, at the same time as it makes such determination, furnish the Company and
the Executive a written opinion to the effect that the Executive has substantial
authority not to report any Excise Tax on his federal, state or local income or
other tax return. As a result of the uncertainty in the application of Section
4999 of the Code (or any successor provision thereto) and


                                       7
<PAGE>

the possibility of similar uncertainty regarding applicable state or local tax
law at the time of any determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made (an "Underpayment"), consistent with the calculations
required to be made hereunder. In the event that the Company exhausts or fails
to pursue its remedies pursuant to Section 5(f) and the Executive thereafter is
required to make a payment of any Excise Tax, the Executive shall direct the
Accounting Firm to determine the amount of the Underpayment that has occurred
and to submit its determination and detailed supporting calculations to both the
Company and the Executive as promptly as possible. Any such Underpayment shall
be promptly paid by the Company to, or for the benefit of, the Executive within
five business days after receipt of such determination and calculations.

                  (c) The Company and the Executive shall each provide the
Accounting Firm access to and copies of any books, records and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise cooperate with the Accounting
Firm in connection with the preparation and issuance of the determinations and
calculations contemplated by this Section 5. Any determination by the Accounting
Firm as to the amount of any Gross-Up Payment or Underpayment shall be binding
upon the Company and the Executive.

                  (d) The federal, state and local income or other tax returns
filed by the Executive shall be prepared and filed on a consistent basis with
the determination of the Accounting Firm with respect to the Excise Tax payable
by the Executive. The Executive shall make proper payment of the amount of any
Excise Tax, and at the request of the Company, provide to the Company true and
correct copies (with any amendments) of his federal income tax return as filed
with the Internal Revenue Service and corresponding state and local tax returns,
if relevant, as filed with the applicable taxing authority, and such other
documents reasonably requested by the Company, evidencing such payment. If prior
to the filing of the Executive's federal income tax return, or corresponding
state or local tax return, if relevant, the Accounting Firm determines that the
amount of the Gross-Up Payment should be reduced, the Executive shall within
five business days pay to the Company the amount of such reduction.

                  (e) The fees and expenses of the Accounting Firm for its
services in connection with the determinations and calculations contemplated by
this Section 5 shall be borne by the Company. If such fees and expenses are
initially paid by the Executive, the Company shall reimburse the Executive the
full amount of such fees and expenses within five business days after receipt
from the Executive of a statement therefor and reasonable evidence of his
payment thereof.

                  (f) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service or any other taxing authority that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such
notification shall be given as promptly as practicable but no later than 10
business days after the Executive actually receives notice of such claim and the
Executive shall further apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid (in each case, to the extent
known by the Executive). The Executive shall not pay such claim prior to the
earlier of (i) the expiration of the 30-calendar-day period following the date
on which he gives such notice to the Company and (ii) the date that any payment
of amount with respect to such claim is due. If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive, subject to the provisions of Section 5(h) of
this Agreement, shall:


                                       8
<PAGE>

                     (i) provide the Company with any written records or
         documents in his possession relating to such claim reasonably requested
         by the Company;

                     (ii) take such action in connection with contesting such
         claim as the Company shall reasonably request in writing from time to
         time, including without limitation accepting legal representation with
         respect to such claim by an attorney competent in respect of the
         subject matter and reasonably selected by the Company;

                     (iii) cooperate with the Company in good faith in order
         effectively to contest such claim; and

                     (iv) permit the Company to participate in any proceedings
         relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including interest and penalties) incurred in connection with such
contest and shall indemnify and hold harmless the Executive, on an after-tax
basis, for and against any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limiting the foregoing provisions of this
Section 5(f), the Company shall control all proceedings taken in connection with
the contest of any claim contemplated by this Section 5(f) and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim
(provided, however, that the Executive may participate therein at his own cost
and expense) and may, at its option, either direct the Executive to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs the Executive to pay the tax claimed and sue for a refund, the
Company shall advance the amount of such payment to the Executive on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income or other tax, including interest
or penalties with respect thereto, imposed with respect to such advance; and
provided further, however, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect
to which the contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of any such contested claim
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

                  (g) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5(f), the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(f)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
any taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5(f), a determination is made
that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial or refund prior to the expiration of 30 calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the


                                       9
<PAGE>

amount of any such advance shall offset, to the extent thereof, the amount of
Gross-Up Payment required to be paid by the Company to the Executive pursuant to
this Section 5.

                  (h) Any information provided by Executive to the Company under
this Section 5 shall be treated confidentially by the Company and will not be
provided by the Company to any other person than the Company's professional
advisors without Executive's prior written consent except as required by law.

         6. NO MITIGATION OBLIGATION: The Company hereby acknowledges that it
will be difficult and may be impossible for the Executive to find reasonably
comparable employment within a reasonable time period following the Termination
Date. In addition, the Company acknowledges that its severance pay plans and
policies applicable in general to its salaried employees typically do not
provide for mitigation, offset or reduction of any severance payments received
thereunder. Accordingly, the payment of the severance compensation by the
Company to the Executive in accordance with the terms of this Agreement is
hereby acknowledged by the Company to be reasonable, and the Executive will not
be required to mitigate the amount of any payment provided for in this Agreement
by seeking other employment or otherwise, nor will any profits, income, earnings
or other benefits from any source whatsoever create any mitigation, offset,
reduction or any other obligation on the part of the Executive hereunder or
otherwise.

         7. LEGAL FEES AND EXPENSES: It is the intent of the Company that the
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement by litigation or otherwise because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if it should appear to the Executive that
the Company has failed to comply with any of its obligations under this
Agreement or in the event that the Company or any other person takes or
threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or proceeding designed to deny, or to
recover from, the Executive the benefits provided or intended to be provided to
the Executive hereunder, the Company irrevocably authorizes the Executive from
time to time to retain counsel of Executive's choice, at the expense of the
Company as hereafter provided, to advise and represent the Executive in
connection with any such interpretation, enforcement or defense, including
without limitation the initiation or defense of any litigation or other legal
action, whether by or against the Company or any Director, officer, stockholder
or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to the Executive's
entering into an attorney-client relationship with such counsel and irrevocably
waives any related conflict of interest on the part of such counsel, and in that
connection the Company and the Executive agree that a confidential relationship
shall exist between the Executive and such counsel. Without respect to whether
the Executive prevails, in whole or in part, in connection with any of the
foregoing, the Company will pay and be solely financially responsible for any
and all attorneys' and related fees and expenses incurred by the Executive in
connection with any of the foregoing.

         8. EMPLOYMENT RIGHTS: Nothing expressed or implied in this Agreement
will create any right or duty on the part of the Company or the Executive to
have the Executive remain in the employment of the Company or any Subsidiary
prior to or following any Change in Control. Any event or occurrence described
in Section 3(b)(i), (ii), (v) or (vi) hereof following the


                                       10
<PAGE>

commencement of a discussion with a third person that ultimately results in a
Change in Control shall be deemed to have occurred after a Change in Control for
the purposes of this Agreement.

         9. WITHHOLDING OF TAXES: The Company may withhold from any amounts
payable under this Agreement all federal, state, city or other taxes as the
Company is required to withhold pursuant to any law or government regulation or
ruling.

         10. SUCCESSORS AND BINDING AGREEMENT: (a) The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization or otherwise) to all or substantially all of the business or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent the Company would be required to perform if no
such succession had taken place. This Agreement will be binding upon and inure
to the benefit of the Company and any successor to the Company, including
without limitation any persons acquiring directly or indirectly all or
substantially all of the business or assets of the Company whether by purchase,
merger, consolidation, reorganization or otherwise (and such successor shall
thereafter be deemed the "Company" for the purposes of this Agreement), but will
not otherwise be assignable, transferable or delegable by the Company.

                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive and the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees and
legatees.

                  (c) This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 10(a) and 10(b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by Executive's
will or by the laws of descent and distribution and, in the event of any
attempted assignment or transfer contrary to this Section 10(c), the Company
shall have no liability to pay any amount so attempted to be assigned,
transferred or delegated.

         11. NOTICES: For all purposes of this Agreement (except as otherwise
expressly provided in this Agreement with respect to notice periods), all
communications, including without limitation notices, consents, requests or
approvals, required or permitted to be given hereunder will be in writing and
will be deemed to have been duly given when hand delivered or dispatched by
electronic facsimile transmission (with receipt thereof orally confirmed), or
ten business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid, or five business days
after having been sent by a nationally recognized overnight courier service such
as Federal Express, UPS, or Purolator, addressed to the Company at 300 Crescent
Court, Suite 1200, Dallas, Texas 75201 (to the attention of the President of the
Company) and to the Executive at the Company's address, with a copy to the
Executive at his or her principal residence, or to such other address as any
party may have furnished to the other in writing and in accordance herewith,
except that notices of changes of address shall be effective only upon receipt.

         12. GOVERNING LAW: The validity, interpretation, construction and
performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of Delaware, without giving effect to the
principles of conflict of laws of such State.


                                       11
<PAGE>

         13. VALIDITY: If any provision of this Agreement or the application of
any provision hereof to any person or circumstances is held invalid,
unenforceable or otherwise illegal, the remainder of this Agreement and the
application of such provision to any other person or circumstances will not be
affected, and the provision so held to be invalid, unenforceable or otherwise
illegal will be reformed to the extent (and only to the extent) necessary to
make it enforceable, valid or legal.

         14. MISCELLANEOUS: No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by the Executive and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto or compliance with
any condition or provision of this Agreement to be performed by such other party
will be deemed a waiver of similar or dissimilar provisions or conditions at the
same or at any prior or subsequent time. No agreements or representations, oral
or otherwise, expressed or implied with respect to the subject matter hereof
have been made by either party which are not set forth expressly in this
Agreement. References to Sections are to references to Sections of this
Agreement.

         15. COUNTERPARTS: This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same agreement.

         16. TERMINATION OF PRIOR AGREEMENTS. The Change in Control Severance
Agreement between the Executive and the Company, dated October 22, 1999, as
amended to the date hereof (the "Prior Agreement"), shall terminate
automatically upon the execution and delivery of this Agreement by the parties
hereto and shall thereafter be of no further force or effect; provided, however,
that if this Agreement is held by a court of competent jurisdiction to be wholly
invalid, unenforceable or otherwise illegal, the preceding clause shall have no
effect and the Prior Agreement shall be deemed to have continued at all times in
full force and effect. Subject to the immediately preceding proviso, this
Agreement supersedes all prior agreements, arrangements and understandings with
respect to the subject matter hereof.

                      CHANGE IN CONTROL SEVERANCE AGREEMENT


         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as
of November 15, 1999, by and between Sterling Software, Inc., a Delaware
corporation (the "Company"), and Don J. McDermett, Jr. (the "Executive").

                                   WITNESSETH:

         WHEREAS, the Executive is a senior executive of the Company and is
expected to make major contributions to the profitability, growth and financial
strength of the Company;

         WHEREAS, the Company recognizes that, as is the case of most companies,
the possibility of a Change in Control (as hereinafter defined) exists;

         WHEREAS, the Company desires to assure itself of both present and
future continuity of management and desires to establish certain minimum
severance benefits for certain of its senior executives, including the
Executive, applicable in the event of a Change in Control; and

         WHEREAS, the Company desires to provide additional inducement for the
Executive to remain in the ongoing employ of the Company;

         NOW, THEREFORE, the Company and the Executive agree as follows:

         1. CERTAIN DEFINED TERMS: In addition to terms defined elsewhere
herein, the following terms have the following meanings when used in this
Agreement with initial capital letters:

                  (a) "Base Pay" means the Executive's annual fixed or base
         compensation, as may be determined from time to time by the Company,

                  person, and as a result of such merger, consolidation or
                  reorganization less than two-thirds of the combined voting
                  power of the then-outstanding securities entitled to vote
                  generally in the election of directors ("Voting Stock") of
                  such corporation or person immediately after such transaction
                  are held in the aggregate by the holders of Voting Stock of

                  of Voting Stock of the Company immediately prior to such sale
                  or transfer;
<PAGE>

                  Schedule 14D-1 (or any successor schedule, form or report),
                  each as promulgated pursuant to the Securities Exchange Act of
                  1934, as amended (the "Exchange Act"), disclosing that any
                  person (as the term "person" is used in Section 13(d)(3) or
                  Section 14(d)(2) of the Exchange Act) has become the
                  beneficial owner (as the term "beneficial owner" is defined
                  under Rule 13d-3 or any successor rule or regulation
                  promulgated under the Exchange Act) of securities representing
                  20% or more of the combined voting power of the

                  14A (or any successor schedule, form or report or item
                  therein) that a change in control of the Company has occurred
                  or will occur in the future pursuant to any then-existing
                  contract or transaction; or

                              (v) If, at any time during any period of two
                  consecutive years, individuals who at the beginning of any
                  such period constitute the Directors of the Company cease for
                  any reason to constitute at least a majority thereof;
                  provided, however, that for purposes of this clause (v) each
                  Director (other than a Director whose initial assumption of
                  office is in connection with an actual or threatened election
                  contest) who is first elected, or first nominated for election
                  by the Company's stockholders, by a vote of at least
                  two-thirds of the Directors of the Company (or a committee
                  thereof) then still in office who were Directors of the
                  Company at the beginning of any such period will be deemed to
                  have been a Director of the Company at the beginning of such
                  period.

         Notwithstanding the foregoing provisions of Sections 1(b)(iii) or
         1(b)(iv), unless otherwise determined in a specific case by majority
         vote of the Board, a "Change in Control" shall not be deemed to have
         occurred for purposes of Section 1(b)(iii) or 1(b)(iv) solely because
         (A) the Company, (B) an entity in which the Company directly or
         indirectly beneficially owns 50% or more of the outstanding Voting
         Stock (a "Subsidiary"), or (C) any Company-sponsored employee stock
         ownership plan or any other employee benefit plan of the Company or any
         Subsidiary either files or becomes obligated to file a report or a
         proxy statement under or in response to Schedule 13D, Schedule 14D-1,
         Form 8-K or Schedule 14A (or any successor schedule, form or report or
         item therein) under the Exchange Act disclosing beneficial ownership by
         it of shares of Voting Stock of the Company, whether in excess of 20%
         or otherwise, or because the Company reports that a change in control
         of the Company has occurred or will occur in the future by reason of
         such beneficial ownership or any increase or decrease thereof.

                  (c) "Employee Benefits" means the perquisites, benefits and
         service credit for perquisites or benefits as provided under any and
         all employee perquisite or benefit policies, plans, programs or
         arrangements in which Executive is entitled to participate, including
         without limitation any stock option, stock purchase, stock
         appreciation, savings, pension, 401(k), employee stock ownership
         (ESOP), employee stock purchase (ESPP), supplemental executive
         retirement, or other retirement income or welfare benefit, deferred
         compensation, incentive compensation, group or other life, health,
         medical/hospital or other insurance (whether funded by actual insurance
         or self-insured by the Company), disability, salary


                                       2

         continuation, expense reimbursement, executive automobile, tax and
         financial planning, club memberships, incentive travel, tax
         reimbursement and other employee benefit policies, plans, programs or
         arrangements that may now exist or any successor policies, plans,
         programs or arrangements that may be adopted hereafter by the Company.

                  (d) "Incentive Pay" means the aggregate annual bonus,
         incentive or other payments of cash compensation, in addition to Base
         Pay, made or authorized or contemplated to be made in regard to
         services rendered by the Executive in any fiscal year pursuant to any
         bonus, incentive compensation, profit-sharing, performance,
         discretionary pay or similar agreement, policy, plan, program or
         arrangement (whether or not funded) of the Company or any successor
         thereto.

                  (e) "Severance Period" means the period of time commencing on
         the date of the first occurrence of a Change in Control and continuing
         until the earliest of (i) the fourth anniversary of the occurrence of
         the Change in Control, or (ii) the Executive's death; provided,
         however, that commencing on each anniversary of the Change in Control,
         the Severance Period will automatically be extended for an additional
         year unless, not later than 90 calendar days prior to such anniversary
         date, either the Company or the Executive shall have given written
         notice to the other that the Severance Period is not to be so extended.

                  (f) "Term" means the period commencing as of the date first
         set forth above and expiring as of the later of (i) the close of
         business on December 31, 2004, or (ii) the expiration of the Severance
         Period; provided, however, that (A) commencing on January 1, 2001 and
         each January 1 thereafter, the Term of this Agreement will
         automatically be extended for an additional year unless, not later than
         September 30 of the immediately preceding year, the Company or the
         Executive shall have given written notice that it or the Executive, as
         the case may be, does not wish to have the Term extended and (B)
         subject to the last sentence of Section 8, if, prior to a Change in
         Control, the Executive ceases for any reason to be an employee of the
         Company or any Subsidiary, thereupon without further action the Term
         shall be deemed to have expired and this Agreement will immediately
         terminate and be of no further effect.

         2. OPERATION OF AGREEMENT: This Agreement will be effective and binding
immediately upon its execution, but, anything in this Agreement to the contrary
notwithstanding, this Agreement will not be operative unless and until a Change
in Control occurs. Upon the occurrence of a Change in Control at any time during
the Term, without further action, this Agreement shall become immediately
operative.

         3. TERMINATION FOLLOWING A CHANGE IN CONTROL: (a) In the event of the
occurrence of a Change in Control, the Executive's employment may be terminated
by the Company during the Severance Period. If, during the Severance Period, the
Executive's employment is terminated by the Company or any Subsidiary other than
as a result of the Executive's death, the Executive will be entitled to the
compensation and benefits provided by Section 4 hereof.

                  (b) In the event of the occurrence of a Change in Control, the
Executive may terminate his or her employment with the Company during the
Severance Period, with the right to the compensation and benefits as provided in
Section 4, upon the occurrence of one or more of the


                                       3
<PAGE>

following events (regardless of whether any other reason for such termination
exists or has occurred, including without limitation, other employment):

                     (i) Failure to elect or reelect or otherwise to maintain
         the Executive in the office of the Company which the Executive held
         immediately prior to a Change in Control, or the removal of the
         Executive as a Director of the Company (or any successor thereto) if
         the Executive shall have been a Director of the Company immediately
         prior to the Change in Control;

                     (ii) (A) A significant adverse change in the nature or
         scope of the authorities, powers, functions, responsibilities or duties
         attached to the position which the Executive held immediately prior to
         the Change in Control, (B) a reduction in the aggregate amount of the
         Executive's Base Pay or Incentive Pay as in effect for the Executive
         immediately prior to the occurrence of a Change in Control or such
         higher amount of Base Pay or Incentive Pay as may thereafter be
         determined by the Company, whether acting through the Board or a
         committee thereof, its President and CEO or otherwise, or (C) the
         termination or denial of the Executive's rights to Employee Benefits or
         a reduction in the scope or value thereof, any of which is not remedied
         by the Company within 10 calendar days after receipt by the Company of
         written notice from the Executive of such change, reduction,
         termination or denial, as the case may be;

                     (iii) A determination by the Executive (which determination
         will be conclusive and binding upon the parties hereto provided it has
         been made in good faith and in all events will be presumed to have been
         made in good faith unless otherwise shown by the Company by clear and
         convincing evidence) that a change in circumstances has occurred
         following a Change in Control, including, without limitation, a change
         in the scope of the business or other activities for which the
         Executive was responsible immediately prior to the Change in Control,
         which has rendered the Executive substantially unable to carry out, has
         substantially hindered Executive's performance of, or has caused
         Executive to suffer a substantial reduction in, any of the authorities,
         powers, functions, responsibilities or duties attached to the position
         held by the Executive immediately prior to the Change in Control, which
         situation is not remedied within 10 calendar days after written notice
         to the Company from the Executive of such determination. For the
         avoidance of doubt, but without limiting the generality of the
         foregoing, if the Company or its successor following a Change in
         Control ceases to be an independent, publicly held, New York Stock
         Exchange-listed company, the Executive may in good faith determine that
         such circumstance, in and of itself, constitutes a substantial
         reduction in his authorities, powers, functions, responsibilities or
         duties;

                     (iv) The liquidation, dissolution, merger, consolidation or
         reorganization of the Company or transfer of all or substantially all
         of its business and/or assets, unless the successor or successors (by
         liquidation, merger, consolidation, reorganization, transfer or
         otherwise) to which all or substantially all of its business and/or
         assets have been transferred (directly or by operation of law) assumed
         all duties and obligations of the Company under this Agreement pursuant
         to Section 10(a);

                     (v) The Company relocates its principal executive offices,
         or requires the Executive to have his principal location of work
         changed, to any location which is in excess


                                       4
<PAGE>

         of 25 miles from the location thereof immediately prior to the Change
         in Control, or requires the Executive to travel away from his office in
         the course of discharging his responsibilities or duties hereunder at
         least 20% more (in terms of aggregate days in any calendar year or in
         any calendar quarter when annualized for purposes of comparison to any
         prior year) than was required of Executive in any of the three full
         years immediately prior to the Change in Control without, in either
         case, his prior written consent; or

                     (vi) Without limiting the generality or effect of the
         foregoing, any material breach of this Agreement by the Company or any
         successor thereto.

                  (c) A termination by the Company pursuant to Section 3(a) or
by the Executive pursuant to Section 3(b) will not affect any rights which the
Executive may have pursuant to any agreement, policy, plan, program or
arrangement of the Company providing Employee Benefits, which rights shall be
governed by the terms thereof. The Company and the Executive are parties to a
Severance Agreement, dated as of November 15, 1999 (as such agreement may be
amended from time to time, the "Severance Agreement"). Notwithstanding anything
contained in this Agreement to the contrary, in the event the Executive's
employment with the Company is terminated under circumstances in which the
Executive would otherwise be entitled to receive payments and benefits under
both this Agreement and the Severance Agreement, the Executive shall have the
right to elect to receive payments and benefits under either this Agreement or
the Severance Agreement, but not both (except that the Executive may in all
events receive all payments and benefits to which he or she is entitled under
the Severance Agreement during the period between the Termination Date and the
Election Date (as such terms are defined below)). Within five business days
following the date of the termination of the Executive's employment with the
Company under the circumstances described in the preceding sentence (the
"Termination Date"), which shall be the effective date of such termination if
the termination is pursuant to Section 3(a) or such other date that may be
specified by the Executive if the termination is pursuant to Section 3(b), the
Company shall provide the Executive, in writing, a reasonably detailed
determination of the payments and other benefits under each of this Agreement
and the Severance Agreement. Executive shall make the election provided for in
this Section 3(c) by providing the Company written notice thereof within 30 days
after the Executive's receipt of the written determination referred to in the
preceding sentence; provided, however, that if such election is not so made
within such 30-day period, the Executive shall be irrevocably deemed to have
elected to receive payments and benefits under this Agreement (the date on which
such election is so made or deemed to have been made being the "Election Date").

         4. SEVERANCE COMPENSATION AND BENEFITS: (a) If, following the
occurrence of a Change in Control, the Company terminates the Executive's
employment during the Severance Period pursuant to Section 3(a) (other than as a
result of the Executive's death), or if the Executive terminates his employment
during the Severance Period pursuant to Section 3(b), the Company will:

                     (i) pay to the Executive, within five business days after
         the Termination Date (or, in the event that the circumstance described
         in Section 3(c) hereof is applicable, within five business days after
         the Election Date), a lump sum payment (the "Severance Payment") in an
         amount equal to four times the sum of (A) Base Pay (the aggregate
         amount and the components of which shall be determined based on the
         highest rate in effect for any period prior to the Termination Date),
         plus (B) Incentive Pay in an amount


                                       5
<PAGE>

         equal to the higher of (i) the highest annual amount of Incentive Pay
         paid to or earned by the Executive with respect to any fiscal year
         during the three fiscal years immediately preceding the fiscal year in
         which the Termination Date occurs, and (ii) 100% of the Incentive Pay
         amount payable upon the attainment of 100% of the objective(s) and 100%
         of the targeted or planned amount(s) specified in or pursuant to the
         applicable agreement, policy, plan, program or arrangement, whether or
         not attained as of such Termination Date, for such Executive for the
         fiscal year in which the Termination Date occurs; provided however,
         that the Severance Payment shall be reduced by the aggregate amount of
         all cash payments, if any, previously received by the Executive
         pursuant to the Severance Agreement prior to the Election Date.

                     (ii) (A) for 48 months following the Termination Date (the
         "Continuation Period"), arrange at its sole expense, to provide the
         Executive with Employee Benefits that are substantially similar to the
         better of (when considered in the aggregate) (X) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Change in Control, or (Y) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Termination Date, and (B) such Continuation
         Period will be considered service with the Company for the purpose of
         determining service credits under or in respect of any Employee
         Benefits applicable to the Executive, his dependents or his
         beneficiaries; provided that for purposes of this Section 4(a)(ii),
         Employee Benefits shall not include any Incentive Pay and nothing in
         this Section 4(a) shall be construed to require the Company to make any
         new grants of stock options to the Executive. If and to the extent that
         any Employee Benefit described in subsection (A) or (B) of this Section
         4(a)(ii) cannot be paid or provided under any applicable law or
         regulation or under the terms of any policy, plan, program or
         arrangement of the Company, then the Company will take all action
         necessary to ensure that such Employee Benefit is provided through
         other means to the Executive, his dependents and beneficiaries, as
         applicable, or the Company shall timely pay to the Executive a lump sum
         amount in cash equal to the fair market value of such foregone Employee
         Benefit. Notwithstanding the immediately preceding sentence, the
         Company shall make any payment that may be necessary to ensure that the
         Executive's after tax position with respect to any Employee Benefits
         received pursuant to this Section 4(a)(ii) is not worse than the
         Executive's after-tax position in the event such Employee Benefits had
         been provided to the Executive while he was employed by the Company.

                     (iii) for the life of the Executive and his or her spouse,
         to (A) arrange to provide (A) the Executive and his or her spouse with
         retiree health benefits substantially identical to the "Benefits" that
         would have been provided to the Executive and his or her spouse under
         the Company's Employee Health Benefit Plan, as amended as of December
         31, 1999 (the "Health Plan"), if the Executive had met the requirements
         of Section 4.01(b)(iii) of the Health Plan as of the "Retiree Record
         Date", and (B) the Executive with the right and opportunity to elect to
         receive health benefits for his or her eligible dependents
         substantially identical to the "Benefits" offered under Section
         4.01(b)(iv) of the Health Plan. The terms "Benefits" and "Retiree
         Record Date" shall have the respective meanings ascribed to such terms
         in the Health Plan.

                  (b) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided


                                       6
<PAGE>

hereunder on a timely basis, the Company will pay interest on the amount or
value thereof at an annualized rate of interest equal to the so-called composite
"prime rate" as quoted from time to time during the relevant period in the
Southwest Edition of THE WALL STREET JOURNAL. Such interest will be payable as
it accrues on demand. Any change in such prime rate will be effective on and as
of the date of such change.

                  (c) Notwithstanding any other provision of this Agreement to
the contrary, the parties' respective rights and obligations under this Section
4 and under Sections 5 and 7 will survive any termination or expiration of this
Agreement or the termination of the Executive's employment following a Change in
Control for any reason whatsoever.

         5. CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY: (a) Anything in this
Agreement to the contrary notwithstanding, in the event that this Agreement
shall become operative and it shall be determined (as hereafter provided) that
all or any portion of any payment or distribution by the Company or any of its
affiliates to or for the benefit of the Executive pursuant to the terms of this
Agreement or otherwise, including under any stock option or other agreement,
plan, policy, program or arrangement (a "Payment"), would be subject to the
excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code") (or any successor provision thereto), by reason of being
considered "contingent on a change in ownership or control" of the Company,
within the meaning of Section 280G of the Code (or any successor provision
thereto), or to any similar tax imposed by state or local law, or any interest
or penalties with respect to such tax (such tax or taxes, together with any such
interest and penalties, being hereafter collectively referred to as the "Excise
Tax"), then the Executive shall be entitled to receive an additional payment or
payments (collectively, a "Gross-Up Payment"); provided, however, that no
Gross-Up Payment shall be made with respect to the Excise Tax, if any,
attributable to (i) any incentive stock option, as defined by Section 422 of the
Code ("ISO") granted prior to the execution of this Agreement, or (ii) any stock
appreciation or similar right, whether or not limited, granted in tandem with an
ISO described in clause (i). The Gross-Up Payment shall be in an amount such
that, after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including any Excise Tax imposed
upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payment.

                  (b) Subject to the provisions of Section 5(f), all
determinations required to be made under this Section 5, including whether an
Excise Tax is payable by the Executive and the amount of such Excise Tax and
whether a Gross-Up Payment is required to be paid by the Company to the
Executive and the amount of such Gross-Up Payment, if any, shall be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive in his sole discretion. The Executive shall direct the Accounting Firm
to submit its determination and detailed supporting calculations to both the
Company and the Executive within 30 calendar days after the Termination Date, if
applicable, and any such other time or times as may be requested by the Company
or the Executive. If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Gross-Up Payment to
the Executive within five business days after receipt of such determination and
calculations with respect to any Gross-Up Payment to the Executive. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall, at the same time as it makes such determination, furnish the Company and
the Executive a written opinion to the effect that the Executive has substantial
authority not to report any Excise Tax on his federal, state or local income or
other tax return. As a result of the uncertainty in the application of Section
4999 of the Code (or any successor provision thereto) and


                                       7
<PAGE>

the possibility of similar uncertainty regarding applicable state or local tax
law at the time of any determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made (an "Underpayment"), consistent with the calculations
required to be made hereunder. In the event that the Company exhausts or fails
to pursue its remedies pursuant to Section 5(f) and the Executive thereafter is
required to make a payment of any Excise Tax, the Executive shall direct the
Accounting Firm to determine the amount of the Underpayment that has occurred
and to submit its determination and detailed supporting calculations to both the
Company and the Executive as promptly as possible. Any such Underpayment shall
be promptly paid by the Company to, or for the benefit of, the Executive within
five business days after receipt of such determination and calculations.

                  (c) The Company and the Executive shall each provide the
Accounting Firm access to and copies of any books, records and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise cooperate with the Accounting
Firm in connection with the preparation and issuance of the determinations and
calculations contemplated by this Section 5. Any determination by the Accounting
Firm as to the amount of any Gross-Up Payment or Underpayment shall be binding
upon the Company and the Executive.

                  (d) The federal, state and local income or other tax returns
filed by the Executive shall be prepared and filed on a consistent basis with
the determination of the Accounting Firm with respect to the Excise Tax payable
by the Executive. The Executive shall make proper payment of the amount of any
Excise Tax, and at the request of the Company, provide to the Company true and
correct copies (with any amendments) of his federal income tax return as filed
with the Internal Revenue Service and corresponding state and local tax returns,
if relevant, as filed with the applicable taxing authority, and such other
documents reasonably requested by the Company, evidencing such payment. If prior
to the filing of the Executive's federal income tax return, or corresponding
state or local tax return, if relevant, the Accounting Firm determines that the
amount of the Gross-Up Payment should be reduced, the Executive shall within
five business days pay to the Company the amount of such reduction.

                  (e) The fees and expenses of the Accounting Firm for its
services in connection with the determinations and calculations contemplated by
this Section 5 shall be borne by the Company. If such fees and expenses are
initially paid by the Executive, the Company shall reimburse the Executive the
full amount of such fees and expenses within five business days after receipt
from the Executive of a statement therefor and reasonable evidence of his
payment thereof.

                  (f) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service or any other taxing authority that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such
notification shall be given as promptly as practicable but no later than 10
business days after the Executive actually receives notice of such claim and the
Executive shall further apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid (in each case, to the extent
known by the Executive). The Executive shall not pay such claim prior to the
earlier of (i) the expiration of the 30-calendar-day period following the date
on which he gives such notice to the Company and (ii) the date that any payment
of amount with respect to such claim is due. If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive, subject to the provisions of Section 5(h) of
this Agreement, shall:


                                       8
<PAGE>

                     (i) provide the Company with any written records or
         documents in his possession relating to such claim reasonably requested
         by the Company;

                     (ii) take such action in connection with contesting such
         claim as the Company shall reasonably request in writing from time to
         time, including without limitation accepting legal representation with
         respect to such claim by an attorney competent in respect of the
         subject matter and reasonably selected by the Company;

                     (iii) cooperate with the Company in good faith in order
         effectively to contest such claim; and

                     (iv) permit the Company to participate in any proceedings
         relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including interest and penalties) incurred in connection with such
contest and shall indemnify and hold harmless the Executive, on an after-tax
basis, for and against any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limiting the foregoing provisions of this
Section 5(f), the Company shall control all proceedings taken in connection with
the contest of any claim contemplated by this Section 5(f) and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim
(provided, however, that the Executive may participate therein at his own cost
and expense) and may, at its option, either direct the Executive to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs the Executive to pay the tax claimed and sue for a refund, the
Company shall advance the amount of such payment to the Executive on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income or other tax, including interest
or penalties with respect thereto, imposed with respect to such advance; and
provided further, however, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect
to which the contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of any such contested claim
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

                  (g) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5(f), the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(f)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
any taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5(f), a determination is made
that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial or refund prior to the expiration of 30 calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the


                                       9
<PAGE>

amount of any such advance shall offset, to the extent thereof, the amount of
Gross-Up Payment required to be paid by the Company to the Executive pursuant to
this Section 5.

                  (h) Any information provided by Executive to the Company under
this Section 5 shall be treated confidentially by the Company and will not be
provided by the Company to any other person than the Company's professional
advisors without Executive's prior written consent except as required by law.

         6. NO MITIGATION OBLIGATION: The Company hereby acknowledges that it
will be difficult and may be impossible for the Executive to find reasonably
comparable employment within a reasonable time period following the Termination
Date. In addition, the Company acknowledges that its severance pay plans and
policies applicable in general to its salaried employees typically do not
provide for mitigation, offset or reduction of any severance payments received
thereunder. Accordingly, the payment of the severance compensation by the
Company to the Executive in accordance with the terms of this Agreement is
hereby acknowledged by the Company to be reasonable, and the Executive will not
be required to mitigate the amount of any payment provided for in this Agreement
by seeking other employment or otherwise, nor will any profits, income, earnings
or other benefits from any source whatsoever create any mitigation, offset,
reduction or any other obligation on the part of the Executive hereunder or
otherwise.

         7. LEGAL FEES AND EXPENSES: It is the intent of the Company that the
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement by litigation or otherwise because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if it should appear to the Executive that
the Company has failed to comply with any of its obligations under this
Agreement or in the event that the Company or any other person takes or
threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or proceeding designed to deny, or to
recover from, the Executive the benefits provided or intended to be provided to
the Executive hereunder, the Company irrevocably authorizes the Executive from
time to time to retain counsel of Executive's choice, at the expense of the
Company as hereafter provided, to advise and represent the Executive in
connection with any such interpretation, enforcement or defense, including
without limitation the initiation or defense of any litigation or other legal
action, whether by or against the Company or any Director, officer, stockholder
or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to the Executive's
entering into an attorney-client relationship with such counsel and irrevocably
waives any related conflict of interest on the part of such counsel, and in that
connection the Company and the Executive agree that a confidential relationship
shall exist between the Executive and such counsel. Without respect to whether
the Executive prevails, in whole or in part, in connection with any of the
foregoing, the Company will pay and be solely financially responsible for any
and all attorneys' and related fees and expenses incurred by the Executive in
connection with any of the foregoing.

         8. EMPLOYMENT RIGHTS: Nothing expressed or implied in this Agreement
will create any right or duty on the part of the Company or the Executive to
have the Executive remain in the employment of the Company or any Subsidiary
prior to or following any Change in Control. Any event or occurrence described
in Section 3(b)(i), (ii), (v) or (vi) hereof following the


                                       10
<PAGE>

commencement of a discussion with a third person that ultimately results in a
Change in Control shall be deemed to have occurred after a Change in Control for
the purposes of this Agreement.

         9. WITHHOLDING OF TAXES: The Company may withhold from any amounts
payable under this Agreement all federal, state, city or other taxes as the
Company is required to withhold pursuant to any law or government regulation or
ruling.

         10. SUCCESSORS AND BINDING AGREEMENT: (a) The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization or otherwise) to all or substantially all of the business or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent the Company would be required to perform if no
such succession had taken place. This Agreement will be binding upon and inure
to the benefit of the Company and any successor to the Company, including
without limitation any persons acquiring directly or indirectly all or
substantially all of the business or assets of the Company whether by purchase,
merger, consolidation, reorganization or otherwise (and such successor shall
thereafter be deemed the "Company" for the purposes of this Agreement), but will
not otherwise be assignable, transferable or delegable by the Company.

                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive and the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees and
legatees.

                  (c) This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 10(a) and 10(b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by Executive's
will or by the laws of descent and distribution and, in the event of any
attempted assignment or transfer contrary to this Section 10(c), the Company
shall have no liability to pay any amount so attempted to be assigned,
transferred or delegated.

         11. NOTICES: For all purposes of this Agreement (except as otherwise
expressly provided in this Agreement with respect to notice periods), all
communications, including without limitation notices, consents, requests or
approvals, required or permitted to be given hereunder will be in writing and
will be deemed to have been duly given when hand delivered or dispatched by
electronic facsimile transmission (with receipt thereof orally confirmed), or
ten business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid, or five business days
after having been sent by a nationally recognized overnight courier service such
as Federal Express, UPS, or Purolator, addressed to the Company at 300 Crescent
Court, Suite 1200, Dallas, Texas 75201 (to the attention of the President of the
Company) and to the Executive at the Company's address, with a copy to the
Executive at his or her principal residence, or to such other address as any
party may have furnished to the other in writing and in accordance herewith,
except that notices of changes of address shall be effective only upon receipt.

         12. GOVERNING LAW: The validity, interpretation, construction and
performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of Delaware, without giving effect to the
principles of conflict of laws of such State.


                                       11
<PAGE>

         13. VALIDITY: If any provision of this Agreement or the application of
any provision hereof to any person or circumstances is held invalid,
unenforceable or otherwise illegal, the remainder of this Agreement and the
application of such provision to any other person or circumstances will not be
affected, and the provision so held to be invalid, unenforceable or otherwise
illegal will be reformed to the extent (and only to the extent) necessary to
make it enforceable, valid or legal.

         14. MISCELLANEOUS: No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by the Executive and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto or compliance with
any condition or provision of this Agreement to be performed by such other party
will be deemed a waiver of similar or dissimilar provisions or conditions at the
same or at any prior or subsequent time. No agreements or representations, oral
or otherwise, expressed or implied with respect to the subject matter hereof
have been made by either party which are not set forth expressly in this
Agreement. References to Sections are to references to Sections of this
Agreement.

         15. COUNTERPARTS: This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same agreement.

         16. TERMINATION OF PRIOR AGREEMENTS. The Change in Control Severance
Agreement between the Executive and the Company, dated October 22, 1999, as
amended to the date hereof (the "Prior Agreement"), shall terminate
automatically upon the execution and delivery of this Agreement by the parties
hereto and shall thereafter be of no further force or effect; provided, however,
that if this Agreement is held by a court of competent jurisdiction to be wholly
invalid, unenforceable or otherwise illegal, the preceding clause shall have no
effect and the Prior Agreement shall be deemed to have continued at all times in
full force and effect. Subject to the immediately preceding proviso, this
Agreement supersedes all prior agreements, arrangements and understandings with
respect to the subject matter hereof.

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as

                                   WITNESSETH:

         WHEREAS, the Executive is a senior executive of the Company and is
expected to make major contributions to the profitability, growth and financial
strength of the Company;

         WHEREAS, the Company recognizes that, as is the case of most companies,
the possibility of a Change in Control (as hereinafter defined) exists;

         WHEREAS, the Company desires to assure itself of both present and
future continuity of management and desires to establish certain minimum
severance benefits for certain of its senior executives, including the
Executive, applicable in the event of a Change in Control; and

         WHEREAS, the Company desires to provide additional inducement for the
Executive to remain in the ongoing employ of the Company;

         NOW, THEREFORE, the Company and the Executive agree as follows:

         1. CERTAIN DEFINED TERMS: In addition to terms defined elsewhere
herein, the following terms have the following meanings when used in this
Agreement with initial capital letters:

                  (a) "Base Pay" means the Executive's annual fixed or base
         compensation, as may be determined from time to time by the Company,

                              (i) The Company is merged, consolidated or
                  reorganized into or with another corporation or other legal

                  reorganization less than two-thirds of the combined voting
                  power of the then-outstanding securities entitled to vote
                  generally in the election of directors ("Voting Stock") of
                  such corporation or person immediately after such transaction

<PAGE>

                  person is held in the aggregate by the holders of Voting Stock
                  of the Company immediately prior to such sale or transfer;

                              (iii) There is a report filed on Schedule 13D or
                  Schedule 14D-1 (or any successor schedule, form or report),

                  1934, as amended (the "Exchange Act"), disclosing that any
                  person (as the term "person" is used in Section 13(d)(3) or
                  Section 14(d)(2) of the Exchange Act) has become the
                  beneficial owner (as the term "beneficial owner" is defined
                  under Rule 13d-3 or any successor rule or regulation
                  promulgated under the Exchange Act) of securities representing
                  20% or more of the combined voting power of the
                  then-outstanding Voting Stock of the Company;

                              (iv) The Company files a report or proxy statement
                  with the Securities and Exchange Commission pursuant to the
                  Exchange Act disclosing in response to Form 8-K or Schedule
                  14A (or any successor schedule, form or report or item
                  therein) that a change in control of the Company has occurred
                  or will occur in the future pursuant to any then-existing
                  contract or transaction; or

                              (v) If, at any time during any period of two
                  consecutive years, individuals who at the beginning of any
                  such period constitute the Directors of the Company cease for
                  any reason to constitute at least a majority thereof;
                  provided, however, that for purposes of this clause (v) each
                  Director (other than a Director whose initial assumption of
                  office is in connection with an actual or threatened election
                  contest) who is first elected, or first nominated for election
                  by the Company's stockholders, by a vote of at least
                  two-thirds of the Directors of the Company (or a committee

                  Company at the beginning of any such period will be deemed to
                  have been a Director of the Company at the beginning of such
                  period.

         Notwithstanding the foregoing provisions of Sections 1(b)(iii) or
         1(b)(iv), unless otherwise determined in a specific case by majority
         vote of the Board, a "Change in Control" shall not be deemed to have
         occurred for purposes of Section 1(b)(iii) or 1(b)(iv) solely because
         (A) the Company, (B) an entity in which the Company directly or
         indirectly beneficially owns 50% or more of the outstanding Voting
         Stock (a "Subsidiary"), or (C) any Company-sponsored employee stock
         ownership plan or any other employee benefit plan of the Company or any
         Subsidiary either files or becomes obligated to file a report or a
         proxy statement under or in response to Schedule 13D, Schedule 14D-1,
         Form 8-K or Schedule 14A (or any successor schedule, form or report or
         item therein) under the Exchange Act disclosing beneficial ownership by
         it of shares of Voting Stock of the Company, whether in excess of 20%
         or otherwise, or because the Company reports that a change in control
         of the Company has occurred or will occur in the future by reason of
         such beneficial ownership or any increase or decrease thereof.

                  (c) "Employee Benefits" means the perquisites, benefits and
         service credit for perquisites or benefits as provided under any and
         all employee perquisite or benefit policies, plans, programs or

         appreciation, savings, pension, 401(k), employee stock ownership
         (ESOP), employee stock purchase (ESPP), supplemental

         insurance or self-insured by the Company), disability, salary
         continuation, expense reimbursement, executive automobile, tax and
         financial planning, club memberships, incentive travel, tax
         reimbursement and other employee benefit policies, plans, programs or

         programs or arrangements that may be adopted hereafter by the Company.

                  (d) "Incentive Pay" means the aggregate annual bonus,
         incentive or other payments of cash compensation, in addition to Base
         Pay, made or authorized or contemplated to be made in regard to
         services rendered by the Executive in any fiscal year pursuant to any
         bonus, incentive compensation, profit-sharing, performance,
         discretionary pay or similar agreement, policy, plan, program or
         arrangement (whether or not funded) of the Company or any successor

         the date of the first occurrence of a Change in Control and continuing
         until the earliest of (i) the second anniversary of the occurrence of
         the Change in Control, or (ii) the Executive's death; provided,
         however, that commencing on each anniversary of the Change in Control,
         the Severance Period will automatically be extended for an additional
         year unless, not later than 90 calendar days prior to such anniversary
         date, either the Company or the Executive shall have given written
         notice to the other that the Severance Period is not to be so extended.

                  (f) "Term" means the period commencing as of the date first
         set forth above and expiring as of the later of (i) the close of
         business on December 31, 2004, or (ii) the expiration of the Severance
         Period; provided, however, that (A) commencing on January 1, 2001 and
         each January 1 thereafter, the Term of this Agreement will
         automatically be extended for an additional year unless, not later than
         September 30 of the immediately preceding year, the Company or the
         Executive shall have given written notice that it or the Executive, as
         the case may be, does not wish to have the Term extended and (B)
         subject to the last sentence of Section 8, if, prior to a Change in
         Control, the Executive ceases for any reason to be an employee of the
         Company or any Subsidiary, thereupon without further action the Term
         shall be deemed to have expired and this Agreement will immediately
         terminate and be of no further effect.

         2. OPERATION OF AGREEMENT: This Agreement will be effective and binding
immediately upon its execution, but, anything in this Agreement to the contrary
notwithstanding, this Agreement will not be operative unless and until a Change
in Control occurs. Upon the occurrence of a Change in Control at any time during
the Term, without further action, this Agreement shall become immediately
operative.

         3. TERMINATION FOLLOWING A CHANGE IN CONTROL: (a) In the event of the
occurrence of a Change in Control, the Executive's employment may be terminated
by the Company during the Severance Period. If, during the Severance Period, the
Executive's employment is terminated by the Company or any Subsidiary other than
as a result of the Executive's death, the Executive will be entitled to the
compensation and benefits provided by Section 4 hereof.

<PAGE>

                  (b) In the event of the occurrence of a Change in Control, the
Executive may terminate his or her employment with the Company during the
Severance Period, with the right to the compensation and benefits as provided in
Section 4, upon the occurrence of one or more of the following events
(regardless of whether any other reason for such termination exists or has
occurred, including without limitation, other employment):

                     (i) Failure to elect or reelect or otherwise to maintain
         the Executive in the office of the Company which the Executive held
         immediately prior to a Change in Control, or the removal of the
         Executive as a Director of the Company (or any successor thereto) if
         the Executive shall have been a Director of the Company immediately
         prior to the Change in Control;

                     (ii) (A) A significant adverse change in the nature or
         scope of the authorities, powers, functions, responsibilities or duties
         attached to the position which the Executive held immediately prior to
         the Change in Control, (B) a reduction in the aggregate amount of the
         Executive's Base Pay or Incentive Pay as in effect for the Executive
         immediately prior to the occurrence of a Change in Control or such
         higher amount of Base Pay or Incentive Pay as may thereafter be
         determined by the Company, whether acting through the Board or a
         committee thereof, its President and CEO or otherwise, or (C) the
         termination or denial of the Executive's rights to Employee Benefits or
         a reduction in the scope or value thereof, any of which is not remedied
         by the Company within 10 calendar days after receipt by the Company of
         written notice from the Executive of such change, reduction,
         termination or denial, as the case may be;

                     (iii) A determination by the Executive (which determination
         will be conclusive and binding upon the parties hereto provided it has
         been made in good faith and in all events will be presumed to have been
         made in good faith unless otherwise shown by the Company by clear and
         convincing evidence) that a change in circumstances has occurred
         following a Change in Control, including, without limitation, a change
         in the scope of the business or other activities for which the
         Executive was responsible immediately prior to the Change in Control,
         which has rendered the Executive substantially unable to carry out, has
         substantially hindered Executive's performance of, or has caused
         Executive to suffer a substantial reduction in, any of the authorities,
         powers, functions, responsibilities or duties attached to the position
         held by the Executive immediately prior to the Change in Control, which
         situation is not remedied within 10 calendar days after written notice
         to the Company from the Executive of such determination;

                     (iv) The liquidation, dissolution, merger, consolidation or
         reorganization of the Company or transfer of all or substantially all
         of its business and/or assets, unless the successor or successors (by
         liquidation, merger, consolidation, reorganization, transfer or
         otherwise) to which all or substantially all of its business and/or
         assets have been transferred (directly or by operation of law) assumed
         all duties and obligations of the Company under this Agreement pursuant
         to Section 10(a);

                     (v) The Company relocates its principal executive offices,
         or requires the Executive to have his principal location of work
         changed, to any location which is in excess


                                       4
<PAGE>

         of 25 miles from the location thereof immediately prior to the Change
         in Control, or requires the Executive to travel away from his office in
         the course of discharging his responsibilities or duties hereunder at
         least 20% more (in terms of aggregate days in any calendar year or in
         any calendar quarter when annualized for purposes of comparison to any
         prior year) than was required of Executive in any of the three full
         years immediately prior to the Change in Control without, in either
         case, his prior written consent; or

                     (vi) Without limiting the generality or effect of the
         foregoing, any material breach of this Agreement by the Company or any
         successor thereto.

                  (c) A termination by the Company pursuant to Section 3(a) or
by the Executive pursuant to Section 3(b) will not affect any rights which the
Executive may have pursuant to any agreement, policy, plan, program or
arrangement of the Company providing Employee Benefits, which rights shall be
governed by the terms thereof. The Company and the Executive are parties to a
Severance Agreement, dated as of October 1, 1996 (as such agreement may be
amended from time to time, the "Severance Agreement"). Notwithstanding anything
contained in this Agreement to the contrary, in the event the Executive's
employment with the Company is terminated under circumstances in which the
Executive would otherwise be entitled to receive payments and benefits under
both this Agreement and the Severance Agreement, the Executive shall have the
right to elect to receive payments and benefits under either this Agreement or
the Severance Agreement, but not both (except that the Executive may in all
events receive all payments and benefits to which he or she is entitled under
the Severance Agreement during the period between the Termination Date and the
Election Date (as such terms are defined below)). Within five business days
following the date of the termination of the Executive's employment with the
Company under the circumstances described in the preceding sentence (the
"Termination Date"), which shall be the effective date of such termination if
the termination is pursuant to Section 3(a) or such other date that may be
specified by the Executive if the termination is pursuant to Section 3(b), the
Company shall provide the Executive, in writing, a reasonably detailed
determination of the payments and other benefits under each of this Agreement
and the Severance Agreement. Executive shall make the election provided for in
this Section 3(c) by providing the Company written notice thereof within 30 days
after the Executive's receipt of the written determination referred to in the
preceding sentence; provided, however, that if such election is not so made
within such 30-day period, the Executive shall be irrevocably deemed to have
elected to receive payments and benefits under this Agreement (the date on which
such election is so made or deemed to have been made being the "Election Date").

         4. SEVERANCE COMPENSATION AND BENEFITS: (a) If, following the
occurrence of a Change in Control, the Company terminates the Executive's
employment during the Severance Period pursuant to Section 3(a) (other than as a
result of the Executive's death), or if the Executive terminates his employment
during the Severance Period pursuant to Section 3(b), the Company will:

                     (i) pay to the Executive, within five business days after
         the Termination Date (or, in the event that the circumstance described
         in Section 3(c) hereof is applicable, within five business days after
         the Election Date), a lump sum payment (the "Severance Payment") in an
         amount equal to two times the sum of (A) Base Pay (the aggregate amount
         and the components of which shall be determined based on the highest
         rate in


                                       5
<PAGE>

         effect for any period prior to the Termination Date), plus (B)
         Incentive Pay in an amount equal to the higher of (i) the highest
         annual amount of Incentive Pay paid to or earned by the Executive with
         respect to any fiscal year during the three fiscal years immediately
         preceding the fiscal year in which the Termination Date occurs, and
         (ii) 100% of the Incentive Pay amount payable upon the attainment of
         100% of the objective(s) and 100% of the targeted or planned amount(s)
         specified in or pursuant to the applicable agreement, policy, plan,
         program or arrangement, whether or not attained as of such Termination
         Date, for such Executive for the fiscal year in which the Termination
         Date occurs; provided however, that the Severance Payment shall be
         reduced by the aggregate amount of all cash payments, if any,
         previously received by the Executive pursuant to the Severance
         Agreement prior to the Election Date.

                     (ii) (A) for 24 months following the Termination Date (the
         "Continuation Period"), arrange at its sole expense, to provide the
         Executive with Employee Benefits that are substantially similar to the
         better of (when considered in the aggregate) (X) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Change in Control, or (Y) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Termination Date, and (B) such Continuation
         Period will be considered service with the Company for the purpose of
         determining service credits under or in respect of any Employee
         Benefits applicable to the Executive, his dependents or his
         beneficiaries; provided that for purposes of this Section 4(a)(ii),
         Employee Benefits shall not include any Incentive Pay and nothing in
         this Section 4(a) shall be construed to require the Company to make any
         new grants of stock options to the Executive. If and to the extent that
         any Employee Benefit described in subsection (A) or (B) of this Section
         4(a)(ii) is not or cannot be paid or provided under any applicable law
         or regulation or under any policy, plan, program or arrangement of the
         Company, then the Company will take all action necessary to ensure that
         such Employee Benefit is provided through other means to the Executive,
         his dependents and beneficiaries, as applicable, or the Company shall
         timely pay to the Executive an amount in cash equal to the fair market
         value of such foregone Employee Benefit.

                  (b) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided hereunder on a timely basis, the Company will pay
interest on the amount or value thereof at an annualized rate of interest equal
to the so-called composite "prime rate" as quoted from time to time during the
relevant period in the Southwest Edition of THE WALL STREET JOURNAL. Such
interest will be payable as it accrues on demand. Any change in such prime rate
will be effective on and as of the date of such change.

                  (c) Notwithstanding any other provision of this Agreement to
the contrary, the parties' respective rights and obligations under this Section
4 and under Sections 5 and 7 will survive any termination or expiration of this
Agreement or the termination of the Executive's employment following a Change in
Control for any reason whatsoever.

         5. CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY: (a) Anything in this
Agreement to the contrary notwithstanding, in the event that this Agreement
shall become operative and it shall be determined (as hereafter provided) that
all or any portion of any payment or distribution by the


                                       6
<PAGE>

Company or any of its affiliates to or for the benefit of the Executive pursuant
to the terms of this Agreement or otherwise, including under any stock option or
other agreement, plan, policy, program or arrangement (a "Payment"), would be
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended (the "Code") (or any successor provision thereto), by reason
of being considered "contingent on a change in ownership or control" of the
Company, within the meaning of Section 280G of the Code (or any successor
provision thereto), or to any similar tax imposed by state or local law, or any
interest or penalties with respect to such tax (such tax or taxes, together with
any such interest and penalties, being hereafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment or payments (collectively, a "Gross-Up Payment"); provided, however,
that no Gross-Up Payment shall be made with respect to the Excise Tax, if any,
attributable to (i) any incentive stock option, as defined by Section 422 of the
Code ("ISO") granted prior to the execution of this Agreement, or (ii) any stock
appreciation or similar right, whether or not limited, granted in tandem with an
ISO described in clause (i). The Gross-Up Payment shall be in an amount such
that, after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including any Excise Tax imposed
upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payment.

                  (b) Subject to the provisions of Section 5(f), all
determinations required to be made under this Section 5, including whether an
Excise Tax is payable by the Executive and the amount of such Excise Tax and
whether a Gross-Up Payment is required to be paid by the Company to the
Executive and the amount of such Gross-Up Payment, if any, shall be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive in his sole discretion. The Executive shall direct the Accounting Firm
to submit its determination and detailed supporting calculations to both the
Company and the Executive within 30 calendar days after the Termination Date, if
applicable, and any such other time or times as may be requested by the Company
or the Executive. If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Gross-Up Payment to
the Executive within five business days after receipt of such determination and
calculations with respect to any Gross-Up Payment to the Executive. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall, at the same time as it makes such determination, furnish the Company and
the Executive a written opinion to the effect that the Executive has substantial
authority not to report any Excise Tax on his federal, state or local income or
other tax return. As a result of the uncertainty in the application of Section
4999 of the Code (or any successor provision thereto) and the possibility of
similar uncertainty regarding applicable state or local tax law at the time of
any determination by the Accounting Firm hereunder, it is possible that Gross-Up
Payments which will not have been made by the Company should have been made (an
"Underpayment"), consistent with the calculations required to be made hereunder.
In the event that the Company exhausts or fails to pursue its remedies pursuant
to Section 5(f) and the Executive thereafter is required to make a payment of
any Excise Tax, the Executive shall direct the Accounting Firm to determine the
amount of the Underpayment that has occurred and to submit its determination and
detailed supporting calculations to both the Company and the Executive as
promptly as possible. Any such Underpayment shall be promptly paid by the
Company to, or for the benefit of, the Executive within five business days after
receipt of such determination and calculations.

                  (c) The Company and the Executive shall each provide the
Accounting Firm access to and copies of any books, records and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise


                                       7
<PAGE>

cooperate with the Accounting Firm in connection with the preparation and
issuance of the determinations and calculations contemplated by this Section 5.
Any determination by the Accounting Firm as to the amount of any Gross-Up
Payment or Underpayment shall be binding upon the Company and the Executive.

                  (d) The federal, state and local income or other tax returns
filed by the Executive shall be prepared and filed on a consistent basis with
the determination of the Accounting Firm with respect to the Excise Tax payable
by the Executive. The Executive shall make proper payment of the amount of any
Excise Tax, and at the request of the Company, provide to the Company true and
correct copies (with any amendments) of his federal income tax return as filed
with the Internal Revenue Service and corresponding state and local tax returns,
if relevant, as filed with the applicable taxing authority, and such other
documents reasonably requested by the Company, evidencing such payment. If prior
to the filing of the Executive's federal income tax return, or corresponding
state or local tax return, if relevant, the Accounting Firm determines that the
amount of the Gross-Up Payment should be reduced, the Executive shall within
five business days pay to the Company the amount of such reduction.

                  (e) The fees and expenses of the Accounting Firm for its
services in connection with the determinations and calculations contemplated by
this Section 5 shall be borne by the Company. If such fees and expenses are
initially paid by the Executive, the Company shall reimburse the Executive the
full amount of such fees and expenses within five business days after receipt
from the Executive of a statement therefor and reasonable evidence of his
payment thereof.

                  (f) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service or any other taxing authority that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such
notification shall be given as promptly as practicable but no later than 10
business days after the Executive actually receives notice of such claim and the
Executive shall further apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid (in each case, to the extent
known by the Executive). The Executive shall not pay such claim prior to the
earlier of (i) the expiration of the 30-calendar-day period following the date
on which he gives such notice to the Company and (ii) the date that any payment
of amount with respect to such claim is due. If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive, subject to the provisions of Section 5(h) of
this Agreement, shall:

                     (i) provide the Company with any written records or
         documents in his possession relating to such claim reasonably requested
         by the Company;

                     (ii) take such action in connection with contesting such
         claim as the Company shall reasonably request in writing from time to
         time, including without limitation accepting legal representation with
         respect to such claim by an attorney competent in respect of the
         subject matter and reasonably selected by the Company;

                     (iii) cooperate with the Company in good faith in order
         effectively to contest such claim; and

                     (iv) permit the Company to participate in any proceedings
         relating to such claim;


                                       8
<PAGE>

provided, however, that the Company shall bear and pay directly all costs and
expenses (including interest and penalties) incurred in connection with such
contest and shall indemnify and hold harmless the Executive, on an after-tax
basis, for and against any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limiting the foregoing provisions of this
Section 5(f), the Company shall control all proceedings taken in connection with
the contest of any claim contemplated by this Section 5(f) and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim
(provided, however, that the Executive may participate therein at his own cost
and expense) and may, at its option, either direct the Executive to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs the Executive to pay the tax claimed and sue for a refund, the
Company shall advance the amount of such payment to the Executive on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income or other tax, including interest
or penalties with respect thereto, imposed with respect to such advance; and
provided further, however, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect
to which the contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of any such contested claim
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

                  (g) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5(f), the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(f)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
any taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5(f), a determination is made
that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial or refund prior to the expiration of 30 calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the amount of any such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid by the
Company to the Executive pursuant to this Section 5.

                  (h) Any information provided by Executive to the Company under
this Section 5 shall be treated confidentially by the Company and will not be
provided by the Company to any other person than the Company's professional
advisors without Executive's prior written consent except as required by law.

         6. NO MITIGATION OBLIGATION: The Company hereby acknowledges that it
will be difficult and may be impossible for the Executive to find reasonably
comparable employment within a reasonable time period following the Termination
Date. In addition, the Company acknowledges that its severance pay plans and
policies applicable in general to its salaried employees typically do not
provide for mitigation, offset or reduction of any severance payments received
thereunder. Accordingly, the payment of the severance compensation by the
Company to the Executive in accordance with the terms of this Agreement is
hereby acknowledged by the


                                       9
<PAGE>

Company to be reasonable, and the Executive will not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, nor will any profits, income, earnings or other benefits from any
source whatsoever create any mitigation, offset, reduction or any other
obligation on the part of the Executive hereunder or otherwise.

         7. LEGAL FEES AND EXPENSES: It is the intent of the Company that the
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement by litigation or otherwise because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if it should appear to the Executive that
the Company has failed to comply with any of its obligations under this
Agreement or in the event that the Company or any other person takes or
threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or proceeding designed to deny, or to
recover from, the Executive the benefits provided or intended to be provided to
the Executive hereunder, the Company irrevocably authorizes the Executive from
time to time to retain counsel of Executive's choice, at the expense of the
Company as hereafter provided, to advise and represent the Executive in
connection with any such interpretation, enforcement or defense, including
without limitation the initiation or defense of any litigation or other legal
action, whether by or against the Company or any Director, officer, stockholder
or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to the Executive's
entering into an attorney-client relationship with such counsel and irrevocably
waives any related conflict of interest on the part of such counsel, and in that
connection the Company and the Executive agree that a confidential relationship
shall exist between the Executive and such counsel. Without respect to whether
the Executive prevails, in whole or in part, in connection with any of the
foregoing, the Company will pay and be solely financially responsible for any
and all attorneys' and related fees and expenses incurred by the Executive in
connection with any of the foregoing.

         8. EMPLOYMENT RIGHTS: Nothing expressed or implied in this Agreement
will create any right or duty on the part of the Company or the Executive to
have the Executive remain in the employment of the Company or any Subsidiary
prior to or following any Change in Control. Any event or occurrence described
in Section 3(b)(i), (ii), (v) or (vi) hereof following the commencement of a
discussion with a third person that ultimately results in a Change in Control
shall be deemed to have occurred after a Change in Control for the purposes of
this Agreement.

         9. WITHHOLDING OF TAXES: The Company may withhold from any amounts
payable under this Agreement all federal, state, city or other taxes as the
Company is required to withhold pursuant to any law or government regulation or
ruling.

         10. SUCCESSORS AND BINDING AGREEMENT: (a) The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization or otherwise) to all or substantially all of the business or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent the Company would be required to perform if no
such succession had taken place. This Agreement will be binding upon and inure
to the benefit of the Company and any successor to the Company, including
without limitation any persons acquiring directly or indirectly all or
substantially all of the business or assets of the Company whether by purchase,
merger, consolidation, reorganization or otherwise (and such successor shall
thereafter be deemed


                                       10
<PAGE>

the "Company" for the purposes of this Agreement), but will not otherwise be
assignable, transferable or delegable by the Company.

                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive and the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees and
legatees.

                  (c) This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 10(a) and 10(b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by Executive's
will or by the laws of descent and distribution and, in the event of any
attempted assignment or transfer contrary to this Section 10(c), the Company
shall have no liability to pay any amount so attempted to be assigned,
transferred or delegated.

         11. NOTICES: For all purposes of this Agreement (except as otherwise
expressly provided in this Agreement with respect to notice periods), all
communications, including without limitation notices, consents, requests or
approvals, required or permitted to be given hereunder will be in writing and
will be deemed to have been duly given when hand delivered or dispatched by
electronic facsimile transmission (with receipt thereof orally confirmed), or
ten business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid, or five business days
after having been sent by a nationally recognized overnight courier service such
as Federal Express, UPS, or Purolator, addressed to the Company at 300 Crescent
Court, Suite 1200, Dallas, Texas 75201 (to the attention of the President of the
Company) and to the Executive at the Company's address, with a copy to the
Executive at his or her principal residence, or to such other address as any
party may have furnished to the other in writing and in accordance herewith,
except that notices of changes of address shall be effective only upon receipt.

         12. GOVERNING LAW: The validity, interpretation, construction and
performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of Delaware, without giving effect to the
principles of conflict of laws of such State.

         13. VALIDITY: If any provision of this Agreement or the application of
any provision hereof to any person or circumstances is held invalid,
unenforceable or otherwise illegal, the remainder of this Agreement and the
application of such provision to any other person or circumstances will not be
affected, and the provision so held to be invalid, unenforceable or otherwise
illegal will be reformed to the extent (and only to the extent) necessary to
make it enforceable, valid or legal.

         14. MISCELLANEOUS: No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to

or otherwise, expressed or implied with respect to the subject matter hereof

effect and the Prior Agreement shall be deemed to have continued at all times in
full force and effect. Subject to the immediately preceding proviso, this
Agreement supersedes all prior agreements, arrangements and understandings with
respect to the subject matter hereof.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be duly

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as
of October 22, 1999, by and between Sterling Software, Inc., a Delaware
corporation (the "Company"), and MARK A. THEEL (the "Executive").

                                   WITNESSETH:

         WHEREAS, the Executive is a senior executive of the Company and is
expected to make major contributions to the profitability, growth and financial
strength of the Company;

         WHEREAS, the Company recognizes that, as is the case of most companies,
the possibility of a Change in Control (as hereinafter defined) exists;

         WHEREAS, the Company desires to assure itself of both present and
future continuity of management and desires to establish certain minimum
severance benefits for certain of its senior executives, including the
Executive, applicable in the event of a Change in Control; and

         WHEREAS, the Company desires to provide additional inducement for the
Executive to remain in the ongoing employ of the Company;

         NOW, THEREFORE, the Company and the Executive agree as follows:

         1. CERTAIN DEFINED TERMS: In addition to terms defined elsewhere

Agreement with initial capital letters:

                  (a) "Base Pay" means the Executive's annual fixed or base
         compensation, as may be determined from time to time by the Company,

                  reorganization less than two-thirds of the combined voting
                  power of the then-outstanding securities entitled to vote
                  generally in the election of directors ("Voting Stock") of
                  such corporation or person immediately after such transaction

                              (iii) There is a report filed on Schedule 13D or

                  1934, as amended (the "Exchange Act"), disclosing that any
                  person (as the term "person" is used in Section 13(d)(3) or
                  Section 14(d)(2) of the Exchange Act) has become the
                  beneficial owner (as the term "beneficial owner" is defined
                  under Rule 13d-3 or any successor rule or regulation
                  promulgated under the Exchange Act) of securities representing
                  20% or more of the combined voting power of the
                  then-outstanding Voting Stock of the Company;

                              (iv) The Company files a report or proxy statement
                  with the Securities and Exchange Commission pursuant to the
                  Exchange Act disclosing in response to Form 8-K or Schedule
                  14A (or any successor schedule, form or report or item
                  therein) that a change in control of the Company has occurred
                  or will occur in the future pursuant to any then-existing
                  contract or transaction; or

                              (v) If, at any time during any period of two
                  consecutive years, individuals who at the beginning of any
                  such period constitute the Directors of the Company cease for
                  any reason to constitute at least a majority thereof;
                  provided, however, that for purposes of this clause (v) each
                  Director (other than a Director whose initial assumption of
                  office is in connection with an actual or threatened election
                  contest) who is first elected, or first nominated for election
                  by the Company's stockholders, by a vote of at least
                  two-thirds of the Directors of the Company (or a committee
                  thereof) then still in office who were Directors of the
                  Company at the beginning of any such period will be deemed to
                  have been a Director of the Company at the beginning of such
                  period.

         Notwithstanding the foregoing provisions of Sections 1(b)(iii) or
         1(b)(iv), unless otherwise determined in a specific case by majority
         vote of the Board, a "Change in Control" shall not be deemed to have
         occurred for purposes of Section 1(b)(iii) or 1(b)(iv) solely because
         (A) the Company, (B) an entity in which the Company directly or
         indirectly beneficially owns 50% or more of the outstanding Voting
         Stock (a "Subsidiary"), or (C) any Company-sponsored employee stock
         ownership plan or any other employee benefit plan of the Company or any
         Subsidiary either files or becomes obligated to file a report or a
         proxy statement under or in response to Schedule 13D, Schedule 14D-1,
         Form 8-K or Schedule 14A (or any successor schedule, form or report or
         item therein) under the Exchange Act disclosing beneficial ownership by
         it of shares of Voting Stock of the Company, whether in excess of 20%
         or otherwise, or because the Company reports that a change in control
         of the Company has occurred or will occur in the future by reason of
         such beneficial ownership or any increase or decrease thereof.

                  (c) "Employee Benefits" means the perquisites, benefits and
         service credit for perquisites or benefits as provided under any and
         all employee perquisite or benefit policies, plans, programs or
         arrangements in which Executive is entitled to participate, including
         without limitation any stock option, stock purchase, stock
         appreciation, savings, pension, 401(k), employee stock ownership
         (ESOP), employee stock purchase (ESPP), supplemental

         executive retirement, or other retirement income or welfare benefit,
         deferred compensation, incentive compensation, group or other life,
         health, medical/hospital or other insurance (whether funded by actual
         insurance or self-insured by the Company), disability, salary
         continuation, expense reimbursement, executive automobile, tax and
         financial planning, club memberships, incentive travel, tax
         reimbursement and other employee benefit policies, plans, programs or
         arrangements that may now exist or any successor policies, plans,
         programs or arrangements that may be adopted hereafter by the Company.

                  (d) "Incentive Pay" means the aggregate annual bonus,
         incentive or other payments of cash compensation, in addition to Base
         Pay, made or authorized or contemplated to be made in regard to
         services rendered by the Executive in any fiscal year pursuant to any
         bonus, incentive compensation, profit-sharing, performance,
         discretionary pay or similar agreement, policy, plan, program or
         arrangement (whether or not funded) of the Company or any successor
         thereto.

                  (e) "Severance Period" means the period of time commencing on
         the date of the first occurrence of a Change in Control and continuing
         until the earliest of (i) the second anniversary of the occurrence of
         the Change in Control, or (ii) the Executive's death; provided,
         however, that commencing on each anniversary of the Change in Control,
         the Severance Period will automatically be extended for an additional
         year unless, not later than 90 calendar days prior to such anniversary
         date, either the Company or the Executive shall have given written
         notice to the other that the Severance Period is not to be so extended.

                  (f) "Term" means the period commencing as of the date first
         set forth above and expiring as of the later of (i) the close of
         business on December 31, 2004, or (ii) the expiration of the Severance
         Period; provided, however, that (A) commencing on January 1, 2001 and
         each January 1 thereafter, the Term of this Agreement will
         automatically be extended for an additional year unless, not later than
         September 30 of the immediately preceding year, the Company or the
         Executive shall have given written notice that it or the Executive, as
         the case may be, does not wish to have the Term extended and (B)
         subject to the last sentence of Section 8, if, prior to a Change in
         Control, the Executive ceases for any reason to be an employee of the
         Company or any Subsidiary, thereupon without further action the Term
         shall be deemed to have expired and this Agreement will immediately
         terminate and be of no further effect.

         2. OPERATION OF AGREEMENT: This Agreement will be effective and binding
immediately upon its execution, but, anything in this Agreement to the contrary
notwithstanding, this Agreement will not be operative unless and until a Change
in Control occurs. Upon the occurrence of a Change in Control at any time during
the Term, without further action, this Agreement shall become immediately
operative.

         3. TERMINATION FOLLOWING A CHANGE IN CONTROL: (a) In the event of the
occurrence of a Change in Control, the Executive's employment may be terminated
by the Company during the Severance Period. If, during the Severance Period, the
Executive's employment is terminated by the Company or any Subsidiary other than
as a result of the Executive's death, the Executive will be entitled to the
compensation and benefits provided by Section 4 hereof.

<PAGE>

                  (b) In the event of the occurrence of a Change in Control, the
Executive may terminate his or her employment with the Company during the
Severance Period, with the right to the compensation and benefits as provided in
Section 4, upon the occurrence of one or more of the following events
(regardless of whether any other reason for such termination exists or has
occurred, including without limitation, other employment):

                     (i) Failure to elect or reelect or otherwise to maintain
         the Executive in the office of the Company which the Executive held
         immediately prior to a Change in Control, or the removal of the
         Executive as a Director of the Company (or any successor thereto) if
         the Executive shall have been a Director of the Company immediately
         prior to the Change in Control;

                     (ii) (A) A significant adverse change in the nature or
         scope of the authorities, powers, functions, responsibilities or duties
         attached to the position which the Executive held immediately prior to
         the Change in Control, (B) a reduction in the aggregate amount of the
         Executive's Base Pay or Incentive Pay as in effect for the Executive
         immediately prior to the occurrence of a Change in Control or such
         higher amount of Base Pay or Incentive Pay as may thereafter be
         determined by the Company, whether acting through the Board or a
         committee thereof, its President and CEO or otherwise, or (C) the
         termination or denial of the Executive's rights to Employee Benefits or
         a reduction in the scope or value thereof, any of which is not remedied
         by the Company within 10 calendar days after receipt by the Company of
         written notice from the Executive of such change, reduction,
         termination or denial, as the case may be;

                     (iii) A determination by the Executive (which determination
         will be conclusive and binding upon the parties hereto provided it has
         been made in good faith and in all events will be presumed to have been
         made in good faith unless otherwise shown by the Company by clear and
         convincing evidence) that a change in circumstances has occurred
         following a Change in Control, including, without limitation, a change
         in the scope of the business or other activities for which the
         Executive was responsible immediately prior to the Change in Control,
         which has rendered the Executive substantially unable to carry out, has
         substantially hindered Executive's performance of, or has caused
         Executive to suffer a substantial reduction in, any of the authorities,
         powers, functions, responsibilities or duties attached to the position
         held by the Executive immediately prior to the Change in Control, which
         situation is not remedied within 10 calendar days after written notice
         to the Company from the Executive of such determination;

                     (iv) The liquidation, dissolution, merger, consolidation or
         reorganization of the Company or transfer of all or substantially all
         of its business and/or assets, unless the successor or successors (by
         liquidation, merger, consolidation, reorganization, transfer or
         otherwise) to which all or substantially all of its business and/or
         assets have been transferred (directly or by operation of law) assumed
         all duties and obligations of the Company under this Agreement pursuant
         to Section 10(a);

                     (v) The Company relocates its principal executive offices,
         or requires the Executive to have his principal location of work
         changed, to any location which is in excess


                                       4
<PAGE>

         of 25 miles from the location thereof immediately prior to the Change
         in Control, or requires the Executive to travel away from his office in
         the course of discharging his responsibilities or duties hereunder at
         least 20% more (in terms of aggregate days in any calendar year or in
         any calendar quarter when annualized for purposes of comparison to any
         prior year) than was required of Executive in any of the three full
         years immediately prior to the Change in Control without, in either
         case, his prior written consent; or

                     (vi) Without limiting the generality or effect of the
         foregoing, any material breach of this Agreement by the Company or any
         successor thereto.

                  (c) A termination by the Company pursuant to Section 3(a) or
by the Executive pursuant to Section 3(b) will not affect any rights which the
Executive may have pursuant to any agreement, policy, plan, program or
arrangement of the Company providing Employee Benefits, which rights shall be
governed by the terms thereof. The Company and the Executive are parties to a
Severance Agreement, dated as of November 1, 1998 (as such agreement may be
amended from time to time, the "Severance Agreement"). Notwithstanding anything
contained in this Agreement to the contrary, in the event the Executive's
employment with the Company is terminated under circumstances in which the
Executive would otherwise be entitled to receive payments and benefits under
both this Agreement and the Severance Agreement, the Executive shall have the
right to elect to receive payments and benefits under either this Agreement or
the Severance Agreement, but not both (except that the Executive may in all
events receive all payments and benefits to which he or she is entitled under
the Severance Agreement during the period between the Termination Date and the
Election Date (as such terms are defined below)). Within five business days
following the date of the termination of the Executive's employment with the
Company under the circumstances described in the preceding sentence (the
"Termination Date"), which shall be the effective date of such termination if
the termination is pursuant to Section 3(a) or such other date that may be
specified by the Executive if the termination is pursuant to Section 3(b), the
Company shall provide the Executive, in writing, a reasonably detailed
determination of the payments and other benefits under each of this Agreement
and the Severance Agreement. Executive shall make the election provided for in
this Section 3(c) by providing the Company written notice thereof within 30 days
after the Executive's receipt of the written determination referred to in the
preceding sentence; provided, however, that if such election is not so made
within such 30-day period, the Executive shall be irrevocably deemed to have
elected to receive payments and benefits under this Agreement (the date on which
such election is so made or deemed to have been made being the "Election Date").

         4. SEVERANCE COMPENSATION AND BENEFITS: (a) If, following the
occurrence of a Change in Control, the Company terminates the Executive's
employment during the Severance Period pursuant to Section 3(a) (other than as a
result of the Executive's death), or if the Executive terminates his employment
during the Severance Period pursuant to Section 3(b), the Company will:

                     (i) pay to the Executive, within five business days after
         the Termination Date (or, in the event that the circumstance described
         in Section 3(c) hereof is applicable, within five business days after
         the Election Date), a lump sum payment (the "Severance Payment") in an
         amount equal to two times the sum of (A) Base Pay (the aggregate amount
         and the components of which shall be determined based on the highest
         rate in


                                       5
<PAGE>

         effect for any period prior to the Termination Date), plus (B)
         Incentive Pay in an amount equal to the higher of (i) the highest
         annual amount of Incentive Pay paid to or earned by the Executive with
         respect to any fiscal year during the three fiscal years immediately
         preceding the fiscal year in which the Termination Date occurs, and
         (ii) 100% of the Incentive Pay amount payable upon the attainment of
         100% of the objective(s) and 100% of the targeted or planned amount(s)
         specified in or pursuant to the applicable agreement, policy, plan,
         program or arrangement, whether or not attained as of such Termination
         Date, for such Executive for the fiscal year in which the Termination
         Date occurs; provided however, that the Severance Payment shall be
         reduced by the aggregate amount of all cash payments, if any,
         previously received by the Executive pursuant to the Severance
         Agreement prior to the Election Date.

                     (ii) (A) for 24 months following the Termination Date (the
         "Continuation Period"), arrange at its sole expense, to provide the
         Executive with Employee Benefits that are substantially similar to the
         better of (when considered in the aggregate) (X) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Change in Control, or (Y) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Termination Date, and (B) such Continuation
         Period will be considered service with the Company for the purpose of
         determining service credits under or in respect of any Employee
         Benefits applicable to the Executive, his dependents or his
         beneficiaries; provided that for purposes of this Section 4(a)(ii),
         Employee Benefits shall not include any Incentive Pay and nothing in
         this Section 4(a) shall be construed to require the Company to make any
         new grants of stock options to the Executive. If and to the extent that
         any Employee Benefit described in subsection (A) or (B) of this Section
         4(a)(ii) is not or cannot be paid or provided under any applicable law
         or regulation or under any policy, plan, program or arrangement of the
         Company, then the Company will take all action necessary to ensure that
         such Employee Benefit is provided through other means to the Executive,
         his dependents and beneficiaries, as applicable, or the Company shall
         timely pay to the Executive an amount in cash equal to the fair market
         value of such foregone Employee Benefit.

                  (b) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided hereunder on a timely basis, the Company will pay
interest on the amount or value thereof at an annualized rate of interest equal
to the so-called composite "prime rate" as quoted from time to time during the
relevant period in the Southwest Edition of THE WALL STREET JOURNAL. Such
interest will be payable as it accrues on demand. Any change in such prime rate
will be effective on and as of the date of such change.

                  (c) Notwithstanding any other provision of this Agreement to
the contrary, the parties' respective rights and obligations under this Section
4 and under Sections 5 and 7 will survive any termination or expiration of this
Agreement or the termination of the Executive's employment following a Change in
Control for any reason whatsoever.

         5. CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY: (a) Anything in this
Agreement to the contrary notwithstanding, in the event that this Agreement
shall become operative and it shall be determined (as hereafter provided) that
all or any portion of any payment or distribution by the


                                       6
<PAGE>

Company or any of its affiliates to or for the benefit of the Executive pursuant
to the terms of this Agreement or otherwise, including under any stock option or
other agreement, plan, policy, program or arrangement (a "Payment"), would be
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended (the "Code") (or any successor provision thereto), by reason
of being considered "contingent on a change in ownership or control" of the
Company, within the meaning of Section 280G of the Code (or any successor
provision thereto), or to any similar tax imposed by state or local law, or any
interest or penalties with respect to such tax (such tax or taxes, together with
any such interest and penalties, being hereafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment or payments (collectively, a "Gross-Up Payment"); provided, however,
that no Gross-Up Payment shall be made with respect to the Excise Tax, if any,
attributable to (i) any incentive stock option, as defined by Section 422 of the
Code ("ISO") granted prior to the execution of this Agreement, or (ii) any stock
appreciation or similar right, whether or not limited, granted in tandem with an
ISO described in clause (i). The Gross-Up Payment shall be in an amount such
that, after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including any Excise Tax imposed
upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payment.

                  (b) Subject to the provisions of Section 5(f), all
determinations required to be made under this Section 5, including whether an
Excise Tax is payable by the Executive and the amount of such Excise Tax and
whether a Gross-Up Payment is required to be paid by the Company to the
Executive and the amount of such Gross-Up Payment, if any, shall be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive in his sole discretion. The Executive shall direct the Accounting Firm
to submit its determination and detailed supporting calculations to both the
Company and the Executive within 30 calendar days after the Termination Date, if
applicable, and any such other time or times as may be requested by the Company
or the Executive. If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Gross-Up Payment to
the Executive within five business days after receipt of such determination and
calculations with respect to any Gross-Up Payment to the Executive. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall, at the same time as it makes such determination, furnish the Company and
the Executive a written opinion to the effect that the Executive has substantial
authority not to report any Excise Tax on his federal, state or local income or
other tax return. As a result of the uncertainty in the application of Section
4999 of the Code (or any successor provision thereto) and the possibility of
similar uncertainty regarding applicable state or local tax law at the time of
any determination by the Accounting Firm hereunder, it is possible that Gross-Up
Payments which will not have been made by the Company should have been made (an
"Underpayment"), consistent with the calculations required to be made hereunder.
In the event that the Company exhausts or fails to pursue its remedies pursuant
to Section 5(f) and the Executive thereafter is required to make a payment of
any Excise Tax, the Executive shall direct the Accounting Firm to determine the
amount of the Underpayment that has occurred and to submit its determination and
detailed supporting calculations to both the Company and the Executive as
promptly as possible. Any such Underpayment shall be promptly paid by the
Company to, or for the benefit of, the Executive within five business days after
receipt of such determination and calculations.

                  (c) The Company and the Executive shall each provide the
Accounting Firm access to and copies of any books, records and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise


                                       7
<PAGE>

cooperate with the Accounting Firm in connection with the preparation and
issuance of the determinations and calculations contemplated by this Section 5.
Any determination by the Accounting Firm as to the amount of any Gross-Up
Payment or Underpayment shall be binding upon the Company and the Executive.

                  (d) The federal, state and local income or other tax returns
filed by the Executive shall be prepared and filed on a consistent basis with
the determination of the Accounting Firm with respect to the Excise Tax payable
by the Executive. The Executive shall make proper payment of the amount of any
Excise Tax, and at the request of the Company, provide to the Company true and
correct copies (with any amendments) of his federal income tax return as filed
with the Internal Revenue Service and corresponding state and local tax returns,
if relevant, as filed with the applicable taxing authority, and such other
documents reasonably requested by the Company, evidencing such payment. If prior
to the filing of the Executive's federal income tax return, or corresponding
state or local tax return, if relevant, the Accounting Firm determines that the
amount of the Gross-Up Payment should be reduced, the Executive shall within
five business days pay to the Company the amount of such reduction.

                  (e) The fees and expenses of the Accounting Firm for its
services in connection with the determinations and calculations contemplated by
this Section 5 shall be borne by the Company. If such fees and expenses are
initially paid by the Executive, the Company shall reimburse the Executive the
full amount of such fees and expenses within five business days after receipt
from the Executive of a statement therefor and reasonable evidence of his
payment thereof.

                  (f) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service or any other taxing authority that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such
notification shall be given as promptly as practicable but no later than 10
business days after the Executive actually receives notice of such claim and the
Executive shall further apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid (in each case, to the extent
known by the Executive). The Executive shall not pay such claim prior to the
earlier of (i) the expiration of the 30-calendar-day period following the date
on which he gives such notice to the Company and (ii) the date that any payment
of amount with respect to such claim is due. If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive, subject to the provisions of Section 5(h) of
this Agreement, shall:

                     (i) provide the Company with any written records or
         documents in his possession relating to such claim reasonably requested
         by the Company;

                     (ii) take such action in connection with contesting such
         claim as the Company shall reasonably request in writing from time to
         time, including without limitation accepting legal representation with
         respect to such claim by an attorney competent in respect of the
         subject matter and reasonably selected by the Company;

                     (iii) cooperate with the Company in good faith in order
         effectively to contest such claim; and

                     (iv) permit the Company to participate in any proceedings
         relating to such claim;


                                       8
<PAGE>

provided, however, that the Company shall bear and pay directly all costs and
expenses (including interest and penalties) incurred in connection with such
contest and shall indemnify and hold harmless the Executive, on an after-tax
basis, for and against any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limiting the foregoing provisions of this
Section 5(f), the Company shall control all proceedings taken in connection with
the contest of any claim contemplated by this Section 5(f) and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim
(provided, however, that the Executive may participate therein at his own cost
and expense) and may, at its option, either direct the Executive to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs the Executive to pay the tax claimed and sue for a refund, the
Company shall advance the amount of such payment to the Executive on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income or other tax, including interest
or penalties with respect thereto, imposed with respect to such advance; and
provided further, however, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect
to which the contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of any such contested claim
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

                  (g) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5(f), the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(f)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
any taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5(f), a determination is made
that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial or refund prior to the expiration of 30 calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the amount of any such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid by the
Company to the Executive pursuant to this Section 5.

                  (h) Any information provided by Executive to the Company under
this Section 5 shall be treated confidentially by the Company and will not be
provided by the Company to any other person than the Company's professional
advisors without Executive's prior written consent except as required by law.

         6. NO MITIGATION OBLIGATION: The Company hereby acknowledges that it
will be difficult and may be impossible for the Executive to find reasonably
comparable employment within a reasonable time period following the Termination
Date. In addition, the Company acknowledges that its severance pay plans and
policies applicable in general to its salaried employees typically do not
provide for mitigation, offset or reduction of any severance payments received
thereunder. Accordingly, the payment of the severance compensation by the
Company to the Executive in accordance with the terms of this Agreement is
hereby acknowledged by the


                                       9
<PAGE>

Company to be reasonable, and the Executive will not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, nor will any profits, income, earnings or other benefits from any
source whatsoever create any mitigation, offset, reduction or any other
obligation on the part of the Executive hereunder or otherwise.

         7. LEGAL FEES AND EXPENSES: It is the intent of the Company that the
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement by litigation or otherwise because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if it should appear to the Executive that
the Company has failed to comply with any of its obligations under this
Agreement or in the event that the Company or any other person takes or
threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or proceeding designed to deny, or to
recover from, the Executive the benefits provided or intended to be provided to
the Executive hereunder, the Company irrevocably authorizes the Executive from
time to time to retain counsel of Executive's choice, at the expense of the
Company as hereafter provided, to advise and represent the Executive in
connection with any such interpretation, enforcement or defense, including
without limitation the initiation or defense of any litigation or other legal
action, whether by or against the Company or any Director, officer, stockholder
or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to the Executive's
entering into an attorney-client relationship with such counsel and irrevocably
waives any related conflict of interest on the part of such counsel, and in that
connection the Company and the Executive agree that a confidential relationship
shall exist between the Executive and such counsel. Without respect to whether
the Executive prevails, in whole or in part, in connection with any of the
foregoing, the Company will pay and be solely financially responsible for any
and all attorneys' and related fees and expenses incurred by the Executive in
connection with any of the foregoing.

         8. EMPLOYMENT RIGHTS: Nothing expressed or implied in this Agreement
will create any right or duty on the part of the Company or the Executive to
have the Executive remain in the employment of the Company or any Subsidiary
prior to or following any Change in Control. Any event or occurrence described
in Section 3(b)(i), (ii), (v) or (vi) hereof following the commencement of a
discussion with a third person that ultimately results in a Change in Control
shall be deemed to have occurred after a Change in Control for the purposes of
this Agreement.

         9. WITHHOLDING OF TAXES: The Company may withhold from any amounts
payable under this Agreement all federal, state, city or other taxes as the
Company is required to withhold pursuant to any law or government regulation or
ruling.

         10. SUCCESSORS AND BINDING AGREEMENT: (a) The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization or otherwise) to all or substantially all of the business or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent the Company would be required to perform if no
such succession had taken place. This Agreement will be binding upon and inure
to the benefit of the Company and any successor to the Company, including
without limitation any persons acquiring directly or indirectly all or
substantially all of the business or assets of the Company whether by purchase,
merger, consolidation, reorganization or otherwise (and such successor shall
thereafter be deemed


                                       10
<PAGE>

the "Company" for the purposes of this Agreement), but will not otherwise be
assignable, transferable or delegable by the Company.

                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive and the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees and
legatees.

                  (c) This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 10(a) and 10(b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by Executive's
will or by the laws of descent and distribution and, in the event of any
attempted assignment or transfer contrary to this Section 10(c), the Company
shall have no liability to pay any amount so attempted to be assigned,
transferred or delegated.

         11. NOTICES: For all purposes of this Agreement (except as otherwise
expressly provided in this Agreement with respect to notice periods), all
communications, including without limitation notices, consents, requests or
approvals, required or permitted to be given hereunder will be in writing and
will be deemed to have been duly given when hand delivered or dispatched by
electronic facsimile transmission (with receipt thereof orally confirmed), or
ten business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid, or five business days
after having been sent by a nationally recognized overnight courier service such
as Federal Express, UPS, or Purolator, addressed to the Company at 300 Crescent
Court, Suite 1200, Dallas, Texas 75201 (to the attention of the President of the
Company) and to the Executive at the Company's address, with a copy to the
Executive at his or her principal residence, or to such other address as any
party may have furnished to the other in writing and in accordance herewith,
except that notices of changes of address shall be effective only upon receipt.

         12. GOVERNING LAW: The validity, interpretation, construction and
performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of Delaware, without giving effect to the
principles of conflict of laws of such State.

         13. VALIDITY: If any provision of this Agreement or the application of
any provision hereof to any person or circumstances is held invalid,
unenforceable or otherwise illegal, the remainder of this Agreement and the
application of such provision to any other person or circumstances will not be
affected, and the provision so held to be invalid, unenforceable or otherwise
illegal will be reformed to the extent (and only to the extent) necessary to
make it enforceable, valid or legal.

         14. MISCELLANEOUS: No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by the Executive and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto or compliance with
any condition or provision of this Agreement to be performed by such other party
will be deemed a waiver of similar or dissimilar provisions or conditions at the
same or at any prior or subsequent time. No agreements or representations, oral
or otherwise, expressed or implied with respect to the subject matter hereof
have been made by either party which


                                       11
<PAGE>

are not set forth expressly in this Agreement. References to Sections are to
references to Sections of this Agreement.

         15. COUNTERPARTS: This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same agreement.

         16. TERMINATION OF PRIOR AGREEMENTS. The Change in Control Severance
Agreement between the Executive and the Company, dated November 1, 1998, as
amended to the date hereof (the "Prior Agreement"), shall terminate
automatically upon the execution and delivery of this Agreement by the parties
hereto and shall thereafter be of no further force or effect; provided, however,
that if this Agreement is held by a court of competent jurisdiction to be wholly
invalid, unenforceable or otherwise illegal, the preceding clause shall have no
effect and the Prior Agreement shall be deemed to have continued at all times in
full force and effect. Subject to the immediately preceding proviso, this
Agreement supersedes all prior agreements, arrangements and understandings with
respect to the subject matter hereof.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed and delivered as of the date first above written.

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this "Agreement"), dated as
of October 22, 1999, by and between Sterling Software, Inc., a Delaware
corporation (the "Company"), and EVAN A. WYLY (the "Executive").

                                   WITNESSETH:

         WHEREAS, the Executive is a senior executive of the Company and is

         WHEREAS, the Company recognizes that, as is the case of most companies,
the possibility of a Change in Control (as hereinafter defined) exists;

         WHEREAS, the Company desires to assure itself of both present and
future continuity of management and desires to establish certain minimum
severance benefits for certain of its senior executives, including the
Executive, applicable in the event of a Change in Control; and

         WHEREAS, the Company desires to provide additional inducement for the
Executive to remain in the ongoing employ of the Company;

         NOW, THEREFORE, the Company and the Executive agree as follows:

         1. CERTAIN DEFINED TERMS: In addition to terms defined elsewhere

         fixed or base compensation, as may be determined from time to time by

         and (ii) the annual fees, if any, paid or payable to the Executive in
         respect of his service during any fiscal year of the Company as a
         member of the Board and any committee thereof.

                              (i) The Company is merged, consolidated or
                  reorganized into or with another corporation or other legal

                  reorganization less than two-thirds of the combined voting
                  power of the then-outstanding securities entitled to vote
                  generally in the election of directors ("Voting Stock") of
                  such corporation or person immediately after such transaction
                  are held in the aggregate by the holders of Voting Stock of

                              (ii) The Company sells or otherwise transfers all

<PAGE>

                  combined voting power of the then-outstanding Voting Stock of
                  such corporation or person is held in the aggregate by the
                  holders of Voting Stock of the Company immediately prior to
                  such sale or transfer;

                              (iii) There is a report filed on Schedule 13D or
                  Schedule 14D-1 (or any successor schedule, form or report),
                  each as promulgated pursuant to the Securities Exchange Act of
                  1934, as amended (the "Exchange Act"), disclosing that any
                  person (as the term "person" is used in Section 13(d)(3) or
                  Section 14(d)(2) of the Exchange Act) has become the
                  beneficial owner (as the term "beneficial owner" is defined
                  under Rule 13d-3 or any successor rule or regulation
                  promulgated under the Exchange Act) of securities representing
                  20% or more of the combined voting power of the
                  then-outstanding Voting Stock of the Company;

                              (iv) The Company files a report or proxy statement
                  with the Securities and Exchange Commission pursuant to the
                  Exchange Act disclosing in response to Form 8-K or Schedule
                  14A (or any successor schedule, form or report or item
                  therein) that a change in control of the Company has occurred
                  or will occur in the future pursuant to any then-existing
                  contract or transaction; or

                              (v) If, at any time during any period of two
                  consecutive years, individuals who at the beginning of any
                  such period constitute the Directors of the Company cease for
                  any reason to constitute at least a majority thereof;
                  provided, however, that for purposes of this clause (v) each
                  Director (other than a Director whose initial assumption of
                  office is in connection with an actual or threatened election
                  contest) who is first elected, or first nominated for election
                  by the Company's stockholders, by a vote of at least
                  two-thirds of the Directors of the Company (or a committee
                  thereof) then still in office who were Directors of the
                  Company at the beginning of any such period will be deemed to
                  have been a Director of the Company at the beginning of such
                  period.

         Notwithstanding the foregoing provisions of Sections 1(b)(iii) or
         1(b)(iv), unless otherwise determined in a specific case by majority
         vote of the Board, a "Change in Control" shall not be deemed to have
         occurred for purposes of Section 1(b)(iii) or 1(b)(iv) solely because
         (A) the Company, (B) an entity in which the Company directly or
         indirectly beneficially owns 50% or more of the outstanding Voting
         Stock (a "Subsidiary"), or (C) any Company-sponsored employee stock
         ownership plan or any other employee benefit plan of the Company or any
         Subsidiary either files or becomes obligated to file a report or a
         proxy statement under or in response to Schedule 13D, Schedule 14D-1,
         Form 8-K or Schedule 14A (or any successor schedule, form or report or
         item therein) under the Exchange Act disclosing beneficial ownership by
         it of shares of Voting Stock of the Company, whether in excess of 20%
         or otherwise, or because the Company reports that a change in control
         of the Company has occurred or will occur in the future by reason of
         such beneficial ownership or any increase or decrease thereof.

                  (c) "Employee Benefits" means the perquisites, benefits and
         service credit for perquisites or benefits as provided under any and
         all employee perquisite or benefit policies, plans, programs or
         arrangements in which Executive is entitled to participate, including
         without limitation any stock option, stock purchase, stock
         appreciation, savings, pension,

         401(k), employee stock ownership (ESOP), employee stock purchase
         (ESPP), supplemental executive retirement, or other retirement income
         or welfare benefit, deferred compensation, incentive compensation,
         group or other life, health, medical/hospital or other insurance
         (whether funded by actual insurance or self-insured by the Company),
         disability, salary continuation, expense reimbursement, executive
         automobile, tax and financial planning, club memberships, incentive
         travel, tax reimbursement and other employee benefit policies, plans,
         programs or arrangements that may now exist or any successor policies,
         plans, programs or arrangements that may be adopted hereafter by the
         Company.

                  (d) "Incentive Pay" means the aggregate annual bonus,
         incentive or other payments of cash compensation, in addition to Base
         Pay, made or authorized or contemplated to be made in regard to
         services rendered by the Executive in any fiscal year pursuant to any
         bonus, incentive compensation, profit-sharing, performance,
         discretionary pay or similar agreement, policy, plan, program or
         arrangement (whether or not funded) of the Company or any successor
         thereto.

                  (e) "Severance Period" means the period of time commencing on
         the date of the first occurrence of a Change in Control and continuing
         until the earliest of (i) the first anniversary of the occurrence of
         the Change in Control, or (ii) the Executive's death; provided,
         however, that commencing on each anniversary of the Change in Control,
         the Severance Period will automatically be extended for an additional
         year unless, not later than 90 calendar days prior to such anniversary
         date, either the Company or the Executive shall have given written
         notice to the other that the Severance Period is not to be so extended.

                  (f) "Term" means the period commencing as of the date first
         set forth above and expiring as of the later of (i) the close of
         business on December 31, 2004, or (ii) the expiration of the Severance
         Period; provided, however, that (A) commencing on January 1, 2001 and
         each January 1 thereafter, the Term of this Agreement will
         automatically be extended for an additional year unless, not later than
         September 30 of the immediately preceding year, the Company or the
         Executive shall have given written notice that it or the Executive, as
         the case may be, does not wish to have the Term extended and (B)
         subject to the last sentence of Section 8, if, prior to a Change in
         Control, the Executive ceases for any reason to be an employee of the
         Company or any Subsidiary, thereupon without further action the Term
         shall be deemed to have expired and this Agreement will immediately
         terminate and be of no further effect.

         2. OPERATION OF AGREEMENT: This Agreement will be effective and binding
immediately upon its execution, but, anything in this Agreement to the contrary
notwithstanding, this Agreement will not be operative unless and until a Change
in Control occurs. Upon the occurrence of a Change in Control at any time during
the Term, without further action, this Agreement shall become immediately
operative.

         3. TERMINATION FOLLOWING A CHANGE IN CONTROL: (a) In the event of the
occurrence of a Change in Control, the Executive's employment may be terminated
by the Company during the Severance Period. If, during the Severance Period, the
Executive's employment is terminated by the Company or any Subsidiary other than
as a result of the Executive's death, the Executive will be entitled to the
compensation and benefits provided by Section 4 hereof.


                                       3
<PAGE>

                  (b) In the event of the occurrence of a Change in Control, the
Executive may terminate his or her employment with the Company during the
Severance Period, with the right to the compensation and benefits as provided in
Section 4, upon the occurrence of one or more of the following events
(regardless of whether any other reason for such termination exists or has
occurred, including without limitation, other employment):

                     (i) Failure to elect or reelect or otherwise to maintain
         the Executive in the office of the Company which the Executive held
         immediately prior to a Change in Control, or the removal of the
         Executive as a Director of the Company (or any successor thereto) if
         the Executive shall have been a Director of the Company immediately
         prior to the Change in Control;

                     (ii) (A) A significant adverse change in the nature or
         scope of the authorities, powers, functions, responsibilities or duties
         attached to the position which the Executive held immediately prior to
         the Change in Control, (B) a reduction in the aggregate amount of the
         Executive's Base Pay or Incentive Pay as in effect for the Executive
         immediately prior to the occurrence of a Change in Control or such
         higher amount of Base Pay or Incentive Pay as may thereafter be
         determined by the Company, whether acting through the Board or a
         committee thereof, its President and CEO or otherwise, or (C) the
         termination or denial of the Executive's rights to Employee Benefits or
         a reduction in the scope or value thereof, any of which is not remedied
         by the Company within 10 calendar days after receipt by the Company of
         written notice from the Executive of such change, reduction,
         termination or denial, as the case may be;

                     (iii) A determination by the Executive (which determination
         will be conclusive and binding upon the parties hereto provided it has
         been made in good faith and in all events will be presumed to have been
         made in good faith unless otherwise shown by the Company by clear and
         convincing evidence) that a change in circumstances has occurred
         following a Change in Control, including, without limitation, a change
         in the scope of the business or other activities for which the
         Executive was responsible immediately prior to the Change in Control,
         which has rendered the Executive substantially unable to carry out, has
         substantially hindered Executive's performance of, or has caused
         Executive to suffer a substantial reduction in, any of the authorities,
         powers, functions, responsibilities or duties attached to the position
         held by the Executive immediately prior to the Change in Control, which
         situation is not remedied within 10 calendar days after written notice
         to the Company from the Executive of such determination;

                     (iv) The liquidation, dissolution, merger, consolidation or
         reorganization of the Company or transfer of all or substantially all
         of its business and/or assets, unless the successor or successors (by
         liquidation, merger, consolidation, reorganization, transfer or
         otherwise) to which all or substantially all of its business and/or
         assets have been transferred (directly or by operation of law) assumed
         all duties and obligations of the Company under this Agreement pursuant
         to Section 10(a);


                                       4
<PAGE>

                     (v) The Company relocates its principal executive offices,
         or requires the Executive to have his principal location of work
         changed, to any location which is in excess of 25 miles from the
         location thereof immediately prior to the Change in Control, or
         requires the Executive to travel away from his office in the course of
         discharging his responsibilities or duties hereunder at least 20% more
         (in terms of aggregate days in any calendar year or in any calendar
         quarter when annualized for purposes of comparison to any prior year)
         than was required of Executive in any of the three full years
         immediately prior to the Change in Control without, in either case, his
         prior written consent; or

                     (vi) Without limiting the generality or effect of the
         foregoing, any material breach of this Agreement by the Company or any
         successor thereto.

                  (c) A termination by the Company pursuant to Section 3(a) or
by the Executive pursuant to Section 3(b) will not affect any rights which the
Executive may have pursuant to any agreement, policy, plan, program or
arrangement of the Company providing Employee Benefits, which rights shall be
governed by the terms thereof. The Company and the Executive are parties to a
Severance Agreement, dated as of February 12, 1996 (as such agreement may be
amended from time to time, the "Severance Agreement"). Notwithstanding anything
contained in this Agreement to the contrary, in the event the Executive's
employment with the Company is terminated under circumstances in which the
Executive would otherwise be entitled to receive payments and benefits under
both this Agreement and the Severance Agreement, the Executive shall have the
right to elect to receive payments and benefits under either this Agreement or
the Severance Agreement, but not both (except that the Executive may in all
events receive all payments and benefits to which he or she is entitled under
the Severance Agreement during the period between the Termination Date and the
Election Date (as such terms are defined below)). Within five business days
following the date of the termination of the Executive's employment with the
Company under the circumstances described in the preceding sentence (the
"Termination Date"), which shall be the effective date of such termination if
the termination is pursuant to Section 3(a) or such other date that may be
specified by the Executive if the termination is pursuant to Section 3(b), the
Company shall provide the Executive, in writing, a reasonably detailed
determination of the payments and other benefits under each of this Agreement
and the Severance Agreement. Executive shall make the election provided for in
this Section 3(c) by providing the Company written notice thereof within 30 days
after the Executive's receipt of the written determination referred to in the
preceding sentence; provided, however, that if such election is not so made
within such 30-day period, the Executive shall be irrevocably deemed to have
elected to receive payments and benefits under this Agreement (the date on which
such election is so made or deemed to have been made being the "Election Date").

         4. SEVERANCE COMPENSATION AND BENEFITS: (a) If, following the
occurrence of a Change in Control, the Company terminates the Executive's
employment during the Severance Period pursuant to Section 3(a) (other than as a
result of the Executive's death), or if the Executive terminates his employment
during the Severance Period pursuant to Section 3(b), the Company will:

                     (i) pay to the Executive, within five business days after
         the Termination Date (or, in the event that the circumstance described
         in Section 3(c) hereof is applicable, within five business days after
         the Election Date), a lump sum payment (the "Severance


                                       5
<PAGE>

         Payment") in an amount equal to one times the sum of (A) Base Pay (the
         aggregate amount and the components of which shall be determined based
         on the highest rate in effect for any period prior to the Termination
         Date), plus (B) Incentive Pay in an amount equal to the higher of (i)
         the highest annual amount of Incentive Pay paid to or earned by the
         Executive with respect to any fiscal year during the three fiscal years
         immediately preceding the fiscal year in which the Termination Date
         occurs, and (ii) 100% of the Incentive Pay amount payable upon the
         attainment of 100% of the objective(s) and 100% of the targeted or
         planned amount(s) specified in or pursuant to the applicable agreement,
         policy, plan, program or arrangement, whether or not attained as of
         such Termination Date, for such Executive for the fiscal year in which
         the Termination Date occurs; provided however, that the Severance
         Payment shall be reduced by the aggregate amount of all cash payments,
         if any, previously received by the Executive pursuant to the Severance
         Agreement prior to the Election Date.

                     (ii) (A) for twelve months following the Termination Date
         (the "Continuation Period"), arrange at its sole expense, to provide
         the Executive with Employee Benefits that are substantially similar to
         the better of (when considered in the aggregate) (X) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Change in Control, or (Y) those Employee
         Benefits which the Executive was receiving or entitled to receive
         immediately prior to the Termination Date, and (B) such Continuation
         Period will be considered service with the Company for the purpose of
         determining service credits under or in respect of any Employee
         Benefits applicable to the Executive, his dependents or his
         beneficiaries; provided that for purposes of this Section 4(a)(ii),
         Employee Benefits shall not include any Incentive Pay and nothing in
         this Section 4(a) shall be construed to require the Company to make any
         new grants of stock options to the Executive. If and to the extent that
         any Employee Benefit described in subsection (A) or (B) of this Section
         4(a)(ii) is not or cannot be paid or provided under any applicable law
         or regulation or under any policy, plan, program or arrangement of the
         Company, then the Company will take all action necessary to ensure that
         such Employee Benefit is provided through other means to the Executive,
         his dependents and beneficiaries, as applicable, or the Company shall
         timely pay to the Executive an amount in cash equal to the fair market
         value of such foregone Employee Benefit.

                  (b) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided hereunder on a timely basis, the Company will pay
interest on the amount or value thereof at an annualized rate of interest equal
to the so-called composite "prime rate" as quoted from time to time during the
relevant period in the Southwest Edition of THE WALL STREET JOURNAL. Such
interest will be payable as it accrues on demand. Any change in such prime rate
will be effective on and as of the date of such change.

                  (c) Notwithstanding any other provision of this Agreement to
the contrary, the parties' respective rights and obligations under this Section
4 and under Sections 5 and 7 will survive any termination or expiration of this
Agreement or the termination of the Executive's employment following a Change in
Control for any reason whatsoever.

         5. CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY: (a) Anything in this
Agreement to the contrary notwithstanding, in the event that this Agreement
shall become operative and it shall be determined (as hereafter provided) that
all or any portion of any payment or distribution by the Company or any of its
affiliates to or for the benefit of the Executive pursuant to the terms of this
Agreement or otherwise, including under any stock option or other agreement,
plan, policy, program or arrangement (a "Payment"), would be subject to the
excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code") (or any successor provision thereto), by reason of being
considered "contingent on a change in ownership or control" of the Company,
within the meaning of Section 280G of the Code (or any successor provision
thereto), or to any similar tax imposed by state or local law, or any interest
or penalties with respect to such tax (such tax or taxes, together with any such
interest and penalties, being hereafter collectively referred to as the "Excise
Tax"), then the Executive shall be entitled to receive an additional payment or
payments (collectively, a "Gross-Up Payment"); provided, however, that no
Gross-Up Payment shall be made with respect to the Excise Tax, if any,
attributable to (i) any incentive stock option, as defined by Section 422 of the
Code ("ISO") granted prior to the execution of this Agreement, or (ii) any stock
appreciation or similar right, whether or not limited, granted in tandem with an
ISO described in clause (i). The Gross-Up Payment shall be in an amount such
that, after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes), including any Excise Tax imposed
upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payment.

                  (b) Subject to the provisions of Section 5(f), all
determinations required to be made under this Section 5, including whether an
Excise Tax is payable by the Executive and the amount of such Excise Tax and
whether a Gross-Up Payment is required to be paid by the Company to the
Executive and the amount of such Gross-Up Payment, if any, shall be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive in his sole discretion. The Executive shall direct the Accounting Firm
to submit its determination and detailed supporting calculations to both the
Company and the Executive within 30 calendar days after the Termination Date, if
applicable, and any such other time or times as may be requested by the Company
or the Executive. If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Gross-Up Payment to
the Executive within five business days after receipt of such determination and
calculations with respect to any Gross-Up Payment to the Executive. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall, at the same time as it makes such determination, furnish the Company and
the Executive a written opinion to the effect that the Executive has substantial
authority not to report any Excise Tax on his federal, state or local income or
other tax return. As a result of the uncertainty in the application of Section
4999 of the Code (or any successor provision thereto) and the possibility of
similar uncertainty regarding applicable state or local tax law at the time of
any determination by the Accounting Firm hereunder, it is possible that Gross-Up
Payments which will not have been made by the Company should have been made (an
"Underpayment"), consistent with the calculations required to be made hereunder.
In the event that the Company exhausts or fails to pursue its remedies pursuant
to Section 5(f) and the Executive thereafter is required to make a payment of
any Excise Tax, the Executive shall direct the Accounting Firm to determine the
amount of the Underpayment that has occurred and to submit its determination and
detailed supporting calculations to both the Company and the Executive as
promptly as possible. Any such Underpayment shall be promptly paid by the
Company to, or for the benefit of, the Executive within five business days after
receipt of such determination and calculations.


                                       7
<PAGE>

                  (c) The Company and the Executive shall each provide the
Accounting Firm access to and copies of any books, records and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise cooperate with the Accounting
Firm in connection with the preparation and issuance of the determinations and
calculations contemplated by this Section 5. Any determination by the Accounting
Firm as to the amount of any Gross-Up Payment or Underpayment shall be binding
upon the Company and the Executive.

                  (d) The federal, state and local income or other tax returns
filed by the Executive shall be prepared and filed on a consistent basis with
the determination of the Accounting Firm with respect to the Excise Tax payable
by the Executive. The Executive shall make proper payment of the amount of any
Excise Tax, and at the request of the Company, provide to the Company true and
correct copies (with any amendments) of his federal income tax return as filed
with the Internal Revenue Service and corresponding state and local tax returns,
if relevant, as filed with the applicable taxing authority, and such other
documents reasonably requested by the Company, evidencing such payment. If prior
to the filing of the Executive's federal income tax return, or corresponding
state or local tax return, if relevant, the Accounting Firm determines that the
amount of the Gross-Up Payment should be reduced, the Executive shall within
five business days pay to the Company the amount of such reduction.

                  (e) The fees and expenses of the Accounting Firm for its
services in connection with the determinations and calculations contemplated by
this Section 5 shall be borne by the Company. If such fees and expenses are
initially paid by the Executive, the Company shall reimburse the Executive the
full amount of such fees and expenses within five business days after receipt
from the Executive of a statement therefor and reasonable evidence of his
payment thereof.

                  (f) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service or any other taxing authority that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such
notification shall be given as promptly as practicable but no later than 10
business days after the Executive actually receives notice of such claim and the
Executive shall further apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid (in each case, to the extent
known by the Executive). The Executive shall not pay such claim prior to the
earlier of (i) the expiration of the 30-calendar-day period following the date
on which he gives such notice to the Company and (ii) the date that any payment
of amount with respect to such claim is due. If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive, subject to the provisions of Section 5(h) of
this Agreement, shall:

                     (i) provide the Company with any written records or
         documents in his possession relating to such claim reasonably requested
         by the Company;

                     (ii) take such action in connection with contesting such
         claim as the Company shall reasonably request in writing from time to
         time, including without limitation accepting legal representation with
         respect to such claim by an attorney competent in respect of the
         subject matter and reasonably selected by the Company;

                     (iii) cooperate with the Company in good faith in order
         effectively to contest such claim; and


                                       8
<PAGE>

                     (iv) permit the Company to participate in any proceedings
         relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including interest and penalties) incurred in connection with such
contest and shall indemnify and hold harmless the Executive, on an after-tax
basis, for and against any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limiting the foregoing provisions of this
Section 5(f), the Company shall control all proceedings taken in connection with
the contest of any claim contemplated by this Section 5(f) and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim
(provided, however, that the Executive may participate therein at his own cost
and expense) and may, at its option, either direct the Executive to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs the Executive to pay the tax claimed and sue for a refund, the
Company shall advance the amount of such payment to the Executive on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income or other tax, including interest
or penalties with respect thereto, imposed with respect to such advance; and
provided further, however, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect
to which the contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of any such contested claim
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

                  (g) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5(f), the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(f)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
any taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5(f), a determination is made
that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial or refund prior to the expiration of 30 calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the amount of any such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid by the
Company to the Executive pursuant to this Section 5.

                  (h) Any information provided by Executive to the Company under
this Section 5 shall be treated confidentially by the Company and will not be
provided by the Company to any other person than the Company's professional
advisors without Executive's prior written consent except as required by law.

         6. NO MITIGATION OBLIGATION: The Company hereby acknowledges that it
will be difficult and may be impossible for the Executive to find reasonably
comparable employment within a reasonable time period following the Termination
Date. In addition, the Company acknowledges that its severance pay plans and
policies applicable in general to its salaried


                                       9
<PAGE>

employees typically do not provide for mitigation, offset or reduction of any
severance payments received thereunder. Accordingly, the payment of the
severance compensation by the Company to the Executive in accordance with the
terms of this Agreement is hereby acknowledged by the Company to be reasonable,
and the Executive will not be required to mitigate the amount of any payment
provided for in this Agreement by seeking other employment or otherwise, nor
will any profits, income, earnings or other benefits from any source whatsoever
create any mitigation, offset, reduction or any other obligation on the part of
the Executive hereunder or otherwise.

         7. LEGAL FEES AND EXPENSES: It is the intent of the Company that the
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement by litigation or otherwise because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if it should appear to the Executive that
the Company has failed to comply with any of its obligations under this
Agreement or in the event that the Company or any other person takes or
threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or proceeding designed to deny, or to
recover from, the Executive the benefits provided or intended to be provided to
the Executive hereunder, the Company irrevocably authorizes the Executive from
time to time to retain counsel of Executive's choice, at the expense of the
Company as hereafter provided, to advise and represent the Executive in
connection with any such interpretation, enforcement or defense, including
without limitation the initiation or defense of any litigation or other legal
action, whether by or against the Company or any Director, officer, stockholder
or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to the Executive's
entering into an attorney-client relationship with such counsel and irrevocably
waives any related conflict of interest on the part of such counsel, and in that
connection the Company and the Executive agree that a confidential relationship
shall exist between the Executive and such counsel. Without respect to whether
the Executive prevails, in whole or in part, in connection with any of the
foregoing, the Company will pay and be solely financially responsible for any
and all attorneys' and related fees and expenses incurred by the Executive in
connection with any of the foregoing.

         8. EMPLOYMENT RIGHTS: Nothing expressed or implied in this Agreement
will create any right or duty on the part of the Company or the Executive to
have the Executive remain in the employment of the Company or any Subsidiary
prior to or following any Change in Control. Any event or occurrence described
in Section 3(b)(i), (ii), (v) or (vi) hereof following the commencement of a
discussion with a third person that ultimately results in a Change in Control
shall be deemed to have occurred after a Change in Control for the purposes of
this Agreement.

         9. WITHHOLDING OF TAXES: The Company may withhold from any amounts
payable under this Agreement all federal, state, city or other taxes as the
Company is required to withhold pursuant to any law or government regulation or
ruling.

         10. SUCCESSORS AND BINDING AGREEMENT: (a) The Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation,
reorganization or otherwise) to all or substantially all of the business or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent the Company would be required to perform if no
such succession had taken place. This Agreement will be binding upon and inure
to the benefit of the Company and


                                       10
<PAGE>

any successor to the Company, including without limitation any persons acquiring
directly or indirectly all or substantially all of the business or assets of the
Company whether by purchase, merger, consolidation, reorganization or otherwise
(and such successor shall thereafter be deemed the "Company" for the purposes of
this Agreement), but will not otherwise be assignable, transferable or delegable
by the Company.

                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive and the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees and
legatees.

                  (c) This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 10(a) and 10(b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by Executive's
will or by the laws of descent and distribution and, in the event of any
attempted assignment or transfer contrary to this Section 10(c), the Company
shall have no liability to pay any amount so attempted to be assigned,
transferred or delegated.

         11. NOTICES: For all purposes of this Agreement (except as otherwise
expressly provided in this Agreement with respect to notice periods), all
communications, including without limitation notices, consents, requests or
approvals, required or permitted to be given hereunder will be in writing and
will be deemed to have been duly given when hand delivered or dispatched by
electronic facsimile transmission (with receipt thereof orally confirmed), or
ten business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid, or five business days
after having been sent by a nationally recognized overnight courier service such
as Federal Express, UPS, or Purolator, addressed to the Company at 300 Crescent
Court, Suite 1200, Dallas, Texas 75201 (to the attention of the President of the
Company) and to the Executive at the Company's address, with a copy to the
Executive at his or her principal residence, or to such other address as any
party may have furnished to the other in writing and in accordance herewith,
except that notices of changes of address shall be effective only upon receipt.

         12. GOVERNING LAW: The validity, interpretation, construction and
performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of Delaware, without giving effect to the
principles of conflict of laws of such State.

         13. VALIDITY: If any provision of this Agreement or the application of
any provision hereof to any person or circumstances is held invalid,
unenforceable or otherwise illegal, the remainder of this Agreement and the
application of such provision to any other person or circumstances will not be
affected, and the provision so held to be invalid, unenforceable or otherwise
illegal will be reformed to the extent (and only to the extent) necessary to
make it enforceable, valid or legal.

         14. MISCELLANEOUS: No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by the Executive and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto or compliance with
any condition or provision of this Agreement to be performed by such other party
will be deemed a waiver of similar or dissimilar provisions or conditions at the


                                       11
<PAGE>

same or at any prior or subsequent time. No agreements or representations, oral
or otherwise, expressed or implied with respect to the subject matter hereof
have been made by either party which are not set forth expressly in this
Agreement. References to Sections are to references to Sections of this
Agreement.

         15. COUNTERPARTS: This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same agreement.

         16. TERMINATION OF PRIOR AGREEMENTS. The Change in Control Severance
Agreement between the Executive and the Company, dated February 12, 1996, as
amended to the date hereof (the "Prior Agreement"), shall terminate
automatically upon the execution and delivery of this Agreement by the parties
hereto and shall thereafter be of no further force or effect; provided, however,
that if this Agreement is held by a court of competent jurisdiction to be wholly
invalid, unenforceable or otherwise illegal, the preceding clause shall have no
effect and the Prior Agreement shall be deemed to have continued at all times in
full force and effect. Subject to the immediately preceding proviso, this
Agreement supersedes all prior agreements, arrangements and understandings with
respect to the subject matter hereof.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed and delivered as of the date first above written.
