                                  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 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.

         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)     upon the payment to the Company by the Executive (or his
                  designee) of the cash surrender value of the split dollar life
                  insurance policy maintained by the Company with respect to the
                  Executive's life, transfer and assign to the Executive (or his
                  designee) all right, title and interest of the Company in and
                  to such split dollar life insurance policy.

                                       2

         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 Executives
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

                                        6
<PAGE>

                  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.

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