Item 1. Security and Subject Company.
 
   The name of the subject company is Interlink Computer Sciences, Inc., a
Delaware corporation (the "Company"). The address of the principal executive
offices of the Company is 47370 Fremont Boulevard, Fremont, California 94538.
The title of the class of equity securities to which this
Solicitation/Recommendation Statement on Schedule 14D-9 (this "Schedule 14D-9"
or "Statement") relates is the common stock, $0.001 par value, of the Company
(the "Common Stock"). Unless the context otherwise requires, as used herein
the term "Shares" shall mean shares of Common Stock and the associated
preferred share purchase rights (the "Rights") issued pursuant to the Rights
Agreement, dated as of February 25, 1998, as amended, between the Company and
BankBoston, N.A. (the "Rights Agreement").
 
Item 2. Tender Offer of the Bidder.
 
   This Statement relates to the cash tender offer (the "Offer") described in
the Offer to Purchase for Cash on Schedule 14D-1, dated March 30, 1999 (as
amended or supplemented, the "Schedule 14D-1"), filed by Sterling Software,
Inc., a Delaware corporation ("Parent"), and Sterling Software (Southwest),
Inc., a Delaware corporation and indirect, wholly-owned subsidiary of Parent
(the "Purchaser"), with the Securities and Exchange Commission (the "SEC"),
relating to an offer to purchase all of the issued and outstanding Shares at
$7.00 per Share (such amount, or any greater amount per Share paid pursuant to
the Offer, hereinafter referred to as the "Offer Consideration"), net to the
seller in cash, upon the terms and subject to the conditions set forth in the
Purchaser's Offer to Purchase dated March 30, 1999 (the "Offer to Purchase")
and in the related Letter of Transmittal (the Schedule 14D-1, the Offer to
Purchase and the Letter of Transmittal, together with any amendments or
supplements thereto, constitute the "Offer Documents").
 
   The Offer is being made in accordance with an Agreement and Plan of Merger,
dated as of March 23, 1999 (the "Merger Agreement"), by and among Parent, the
Purchaser and the Company. Pursuant to the Merger Agreement, following
completion of the Offer and satisfaction or waiver, if permissible, of certain
conditions, the Purchaser will be merged with and into the Company (the
"Merger"), and the Company will become an indirect, wholly-owned subsidiary of
Parent (the "Surviving Corporation"). At the effective time of the Merger (the
"Effective Time"), each Share issued and outstanding immediately prior to the
Effective Time (other than Shares held by Parent or the Purchaser or any other
subsidiary of Parent and Shares held by stockholders of the Company who will
have properly perfected their dissenter's rights, if any, under Delaware law)
will be converted into the right to receive the Offer Consideration without
interest thereon. The Merger Agreement is summarized in Item 3 of this
Schedule 14D-9.
 
   The Offer Documents indicate that the principal executive offices of Parent
and the Purchaser are located at 300 Crescent Court, Suite 1200, Dallas, Texas
75201-7853.
 
Item 3. Identity and Background.
 
   (a) Name and Address of the Company.
 
   The name and address of the Company, which is the person filing this
Schedule 14D-9, are set forth in Item 1 above.
 
   (b)(i) Arrangements with the Company's Executive Offices, Directors or
Affiliates.
 
   Certain contracts, agreements, arrangements or understandings between the
Company or its affiliates and certain of its executive officers, directors or
affiliates are described in the Company's Proxy Statement, dated September 18,
1998, relating to its 1998 Annual Meeting of Stockholders (the "Proxy
Statement") under the headings "Security Ownership of Certain Beneficial
Owners and Management," "Executive Compensation and Other Matters," "Director
Compensation," "Option Grants in Fiscal Year 1998," "Aggregate Option Exercise
in Last Fiscal Year and Fiscal Year-End Values," "Employment Agreements and
Change in Control
 
                                       1
<PAGE>
 
Arrangements," "Report of the Compensation Committee," and "Ten-Year Option
Repricings." A copy of the applicable portions of the Proxy Statement has been
filed as Exhibit 99.19 to this Schedule 14D-9 and such portions of the Proxy
Statement are incorporated herein by reference.
 
   Each of the Company's executive officers and directors has entered into one
or more option agreements with the Company pursuant to the Company's 1992
Stock Option Plan and the Company's 1996 Director Option Plan, respectively.
All such options will become fully vested at the time of the consummation of
the Offer, as more fully described below under "The Merger Agreement--
Treatment of Stock Option Plans, Stock Purchase Plans and Warrants."
 
   Under a Consulting Agreement with James A. Barth, formerly the Company's
Chief Financial Officer and Vice President of Finance, the unvested portion of
all stock options held by him under the Company's 1992 Stock Option Plan will
become fully exercisable either (i) immediately prior to the closing of the
Offer (the "Closing") or (ii) upon the signing of a definitive acquisition
agreement for the sale of the Company to any entity other than Purchaser
during the term of the consulting agreement. Any vested stock options held by
Mr. Barth will remain exercisable until the later of (i) the date specified in
Mr. Barth's option agreements under the 1992 Stock Option Plan, or (ii) thirty
(30) days after the Merger Agreement is terminated in accordance with its
terms.
 
   The Company's executive officers are eligible to participate in the
Company's 1996 Employee Stock Purchase Plan (the "ESPP") pursuant to which
such officers are entitled to purchase Common Stock of the Company through
payroll deductions. The Offering Period (as defined in the ESPP) currently in
progress under the ESPP will terminate on the earlier of April 30, 1999 or the
consummation of the Offer, to the extent the consummation of the Offer occurs
prior to April 30, 1999. The ESPP will terminate immediately after the close
of the current Offering Period.
 
   Each of the Company's executive officers is also covered by the Company's
severance program which provides for severance equal to six months of base
salary for termination without cause, unless otherwise agreed by the executive
officer and the Company's Board of Directors.
 
   The Company's Certificate of Incorporation provides that (i) a director of
the Company shall not be liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except to the
extent such exemption from liability is not permitted by the Delaware General
Corporation Law ("DGCL") and (ii) the Company may indemnify to the fullest
extent permitted by law any person made or threatened to be made a party to an
action or proceeding, whether criminal, civil, administrative or
investigative, by reason of the fact that he, his testator or intestate is or
was a director, officer or employee of the corporation or any predecessor of
the corporation or serves or served at any other enterprise as a director,
officer or employee at the request of the corporation or any predecessor to
the corporation.
 
   The Company's Bylaws provide that the Company shall, to the maximum extent
and in the manner permitted by the DGCL, indemnify each of its directors and
officers against expenses (including attorneys' fees), judgments, fines,
settlements and other amounts actually and reasonably incurred in connection
with any proceeding, arising by reason of the fact that such person is or was
an agent of the corporation where, a "director" or "officer" of the
corporation includes any person (i) who is or was a director or officer of the
corporation, (ii) who is or was serving at the request of the corporation as a
director or officer of another corporation, partnership, joint venture, trust
or other enterprise, or (iii) who was a director or officer of a corporation
which was a predecessor corporation of the corporation or of another
enterprise at the request of such predecessor corporation.
 
   The Company has previously entered into indemnification agreements with
each of its directors and executive officers. The indemnification agreements
generally provide for: (i) indemnification to the fullest extent permitted by
law if an indemnitee was or is or becomes party to or witness or other
participant in, or is threatened to be made a party to or witness or other
participant in, any threatened, pending or completed action, suit, proceeding
or alternative dispute resolution mechanism, or any hearing, inquiry or
investigation that the
 
                                       2
<PAGE>
 
indemnitee in good faith believes might lead to the institution of any such
action, suit, proceeding or alternative dispute resolution mechanism, whether
civil, criminal, administrative, investigative or other, by reason of (or
arising in part out of) any event or occurrence related to the fact that the
indemnitee is or was a director, officer, employee, agent or fiduciary of the
Company, or any subsidiary of the Company, or is or was serving at the request
of the Company as a director, officer, employee, agent or fiduciary of another
corporation, partnership, joint venture, trust or other enterprise, or by
reason of any action or inaction on the part of the indemnitee while serving
in such capacity against any and all expenses (including attorneys' fees and
all other costs, expenses and obligations incurred in connection with
investigating, defending, being a witness in or participating in (including on
appeal), or preparing to defend, be a witness in or participate in, any such
action, suit, proceeding, alternative dispute resolution mechanism, hearing,
inquiry or investigation), judgments, fines, penalties and amounts paid in
settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) of the claim and any federal,
state, local or foreign taxes imposed on such person as a result of actual or
deemed receipt of any payment under the indemnification agreement and (ii)
advancement of all expenses incurred by the indemnitee.
 
   (ii) Arrangements with Sterling Software, Inc., its Executive Officers,
Directors and Affiliates.
 
The Merger Agreement
 
   The following is a summary of certain provisions of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the complete
text of the Merger Agreement, which is filed with the SEC as Exhibit 99.1 to
this Schedule 14D-9 and is incorporated herein by reference. For purposes of
this Item 3(b)(ii), all capitalized terms not defined herein shall have the
definitions assigned to them in the Merger Agreement.
 
   The Offer. The Merger Agreement provides for the commencement of the Offer
as promptly as practicable, but in no event later than five business days
after the initial public announcement of the execution and delivery of the
Merger Agreement. The obligation of Purchaser to accept for payment and pay
for the Shares tendered pursuant to the Offer is subject to the satisfaction
of (i) the Minimum Condition (as described in the "Conditions to the Offer"
section below) prior to the expiration of the Offer and (ii) certain other
conditions described in the "Conditions to the Offer" section below. The
Merger Agreement provides that without the prior written consent of the
Company, Purchaser will not (and Parent shall cause Purchaser not to) (i)
decrease or change the form of the Offer Consideration or decrease the number
of Shares sought pursuant to the Offer, (ii) impose additional conditions to
the Offer, (iii) extend the expiration date of the Offer beyond the initial
expiration date of the Offer (which shall be the 20th business day after
commencement of the Offer), except (A) as required by applicable law, (B) that
if, immediately prior to the expiration date of the Offer (as it may be
extended), the Shares tendered and not withdrawn pursuant to the Offer
constitute more than 75% and less than 90% of the outstanding Shares,
Purchaser may extend the Offer for one or more periods not to exceed an
aggregate of ten business days, notwithstanding that all conditions to the
Offer are satisfied as of such expiration date of the Offer and (C) that if
any condition to the Offer has not been satisfied or waived, Purchaser may, in
its sole discretion, extend the expiration date of the Offer for one or more
periods, provided that the expiration date of the Offer may not be extended
beyond July 31, 1999, (iv) waive the Minimum Condition, or (v) amend any term
or other condition of the Offer in any manner materially adverse to holders of
Shares; provided, however, that, except as set forth above and subject to
applicable legal requirements, Purchaser may waive any condition to the Offer
other than the Minimum Condition in its sole discretion; and provided further
that the Offer may be extended in connection with an increase in the
consideration to be paid pursuant to the Offer so as to comply with applicable
rules and regulations of the SEC. Purchaser will, on the terms and subject to
the prior satisfaction or waiver of the conditions of the Offer, accept for
payment, and pay for, in accordance with the terms and subject to the
conditions of the Offer, all Shares validly tendered and not withdrawn
pursuant to the Offer as soon as practicable after the expiration date
thereof. Notwithstanding the foregoing, if all the conditions to the Offer
have not been satisfied or waived at the initial expiration date of the Offer
and all such conditions are reasonably capable of being satisfied within the
applicable period set forth below, the Purchaser shall (i) extend the Offer
for 10 business days from the initial expiration date of the Offer or (ii)
extend the Offer for 20 business days from the
 
                                       3
<PAGE>
 
initial expiration date of the Offer if the waiting periods under the HSR Act
applicable to the Merger have not expired or been earlier terminated and are
reasonably capable of being satisfied.
 
   Directors. The Merger Agreement provides that, subject to compliance with
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, after
Purchaser or any of its affiliates own beneficially at least a majority of
then outstanding Shares, Parent will be entitled to designate such number of
directors, rounded up to the next whole number, on the Company's Board of
Directors as is equal to the product of the total number of directors on such
Board (after giving effect to any increase in the size of such Board)
multiplied by the percentage that the number of Shares beneficially owned by
Purchaser at such time (including Shares so accepted for payment) bears to the
total number of Shares then outstanding. The Company has further agreed, upon
request of Parent, to use its best efforts promptly either to increase the
size of its Board of Directors or to secure the resignations of such number of
its incumbent directors, or both, as is necessary to enable such designees of
Parent to be so elected or appointed to the Company's Board of Directors, and
to take all actions available to the Company to cause such designees of Parent
to be so elected or appointed. The Company will, if requested by Parent, also
take all action necessary to cause persons designated by Parent to constitute
at least the same percentage (rounded up to the next whole number) as Parent
is entitled to designate on the Company's Board of Directors of each committee
of the Company's Board of Directors, each board of directors (or similar body)
of each subsidiary of the Company and each committee (or similar body) of each
such board.
 
   Notwithstanding the provisions described above, the parties have agreed to
ensure that at least two of the members of the Company's Board of Directors
shall, at all times prior to the Effective Time (as defined below), be
directors of the Company who were directors of the Company on the date of the
Merger Agreement (the "Continuing Directors"). If the number of Continuing
Directors shall be reduced below two for any reason, the remaining Continuing
Director may designate a person to fill such vacancy who will be deemed to be
a Continuing Director, or if no Continuing Directors then remain, the other
directors of the Company then in office will designate two persons to fill
such vacancies who will not be officers or employees or affiliates of the
Company, Parent or either of their subsidiaries and such persons shall be
deemed to be Continuing Directors. Once Parent's designees constitute a
majority of the Company's Board of Directors and prior to the Effective Time,
any amendment or modification of the Merger Agreement, any amendment to the
Company's Certificate of Incorporation or Bylaws inconsistent with the Merger
Agreement, any termination of the Merger Agreement by the Company, any
extension of time for performance of any of the obligations of Parent or
Purchaser under the Merger Agreement, any waiver of any condition to the
Company's obligations under the Merger Agreement or any of the Company's
rights under the Merger Agreement or other action by the Company under the
Merger Agreement may be effected only by the action of a majority of the
Continuing Directors of the Company, which action will be deemed to constitute
the action of any committee specifically designated by the Board of Directors
of the Company to approve the actions contemplated under the Merger Agreement
and the full Board of Directors of the Company; provided, that, if there are
no Continuing Directors, such actions may be effected by majority vote of the
entire Board of Directors of the Company.
 
   The Merger. The Merger Agreement provides that, and in accordance with the
DGCL, the Merger shall be effected as soon as practicable, but in no event
later than 10:00 a.m. on the tenth business day (the "Closing Date") following
satisfaction or waiver of all of the conditions to the Merger, other than
those conditions that by their nature are to be satisfied at the Closing,
subject to the fulfillment or waiver of those conditions, and the Purchaser
shall be merged with and into the Company upon the filing of a certificate of
merger with the Delaware State Secretary, or at such later time as is
specified in the certificate of merger (the "Effective Time"). At the
Effective Time, the separate existence of Purchaser shall cease and the
Company shall continue as the surviving corporation (as such, the "Surviving
Corporation") and shall continue to be governed by the laws of the State of
Delaware.
 
   Company Stockholders Meeting; Preparation of the Proxy Statement; Short-
Form Merger. In the Merger Agreement, the Company has agreed, as soon as
practicable following the acceptance for payment of and payment for Shares by
Purchaser in the Offer, if required by law to consummate the Merger, to hold a
special meeting of the stockholders of the Company (the "Stockholders
Meeting") for the purpose of considering and
 
                                       4
<PAGE>
 
voting upon the Merger Agreement and to solicit proxies pursuant to a proxy
statement prepared and filed in connection therewith. The Company's Board of
Directors will recommend that the holders of Shares vote in favor of the
adoption of the Merger Agreement at the Stockholders Meeting and will cause
such recommendation to be included in the proxy statement. At the Stockholders
Meeting, Parent and Purchaser will cause all of the Shares owned by them to be
voted in favor of the adoption of the Merger Agreement.
 
   In the event that Purchaser or any other wholly owned subsidiary of Parent
shall acquire at least 90% of the outstanding Shares in the Offer, the parties
to the Merger Agreement will, at the request of Purchaser, take all necessary
actions to cause the Merger to become effective, as soon as practicable after
the expiration of the Offer, without a meeting of stockholders of the Company,
in accordance with Section 253 of the DGCL.
 
   Conversion of Securities. At the Effective Time, by virtue of the Merger
and without any action on the part of any holder of Shares or any other shares
of capital stock of the Company or Purchaser, each Share (including the
associated Rights) issued and outstanding immediately prior to the Effective
Time (other than Shares held by the Company or any subsidiary of the Company
or by Parent, Purchaser or any other subsidiary of Parent (other than shares
in trust accounts, managed accounts, custodial accounts and the like that are
beneficially owned by third parties) and any Shares with respect to which
dissenters rights are properly exercised) shall be converted into the right to
receive the Offer Consideration, payable to the holder thereof, without any
interest thereon (the "Merger Consideration"), less any required withholding
taxes, upon surrender and exchange of the certificates representing such
Shares. Each share of common stock of Purchaser issued and outstanding
immediately prior to the Effective Time shall be converted into and become one
validly issued, fully paid and outstanding share of Common Stock to the
Surviving Corporation.
 
   Treatment of Stock Option Plans, Stock Purchase Plans and Warrants. The
parties have agreed that neither the Purchaser nor the Parent will assume the
outstanding options to purchase Shares (collectively, the "Options") under the
Company's 1992 Stock Option Plan and 1996 Director Stock Option Plan
(collectively, the "Stock Option Plans") or substitute an option to purchase
Parent or Purchaser common stock in respect of the Options. Options under the
Stock Option Plans will become fully vested and otherwise treated in
accordance with the terms of the applicable Stock Option Plan document and the
various agreements evidencing the Options. In addition, the Company has agreed
to take all action as shall be necessary or appropriate to cause all Options
under the Stock Option Plans to expire no later than the Effective Time.
 
   Offering Period. The Offering Period currently in progress under the ESPP
will terminate on the earlier of April 30, 1999 or the consummation of the
Offer, to the extent the consummation of the Offer occurs prior to April 30,
1999. The ESPP will terminate immediately after the close of the current
Offering Period.
 
   Parent and Purchaser will not assume or continue any outstanding warrants
to purchase Shares (the "Warrants"). The parties to the Merger Agreement will
take all appropriate action to provide that, in accordance with the respective
terms of the Warrants, at or prior to the Effective Time, each holder of an
outstanding Warrant will be entitled to receive an amount in cash equal to the
product of (i) the excess, if any, of the Offer Consideration over the per
Share exercise price of such Warrant and (ii) the number of Shares subject to
such Warrant.
 
   Representations and Warranties. The Merger Agreement contains various
representations and warranties of the parties. These include representations
and warranties by the Company with respect to, among other things, (i)
organization, standing and corporate power, (ii) authority and
noncontravention, (iii) consents and approvals, (iv) capital structure, (v)
SEC filings and documents, (vi) absence of certain changes or events, no
undisclosed material liabilities, (vii) certain information, (viii) real
property and other assets, (ix) software, (x) intellectual property, (xi) no
infringement, (xii) material contracts, (xiii) litigation, etc., (xiv)
compliance with applicable laws, (xv) environmental laws, (xvi) taxes, (xvii)
benefit plans, (xviii) absence of changes in benefit plans, (xix) labor
matters, (xx) brokers, (xxi) written opinion of financial advisor, (xxii)
voting requirements, (xxiii) the amendment of the Rights Agreement, (xxiv) the
Company's recent settlement of certain litigation, and (xxv) confidentiality
agreements with third parties containing "standstill" provisions.
 
                                       5
<PAGE>
 
   Parent and the Purchaser also have made certain representations and
warranties with respect to, among other things, (i) organization, standing and
corporate power, (ii) authority and noncontravention, (iii) consents and
approvals, (iv) certain information, (v) financing and (vi) interim operations
of the Purchaser.
 
   Certain representations and warranties in the Merger Agreement are
qualified as to "materiality" or "Material Adverse Effect". For the purposes
of the Merger Agreement and this Offer to Purchase, "Material Adverse Effect"
with respect to any person means any event, change, occurrence, effect, fact
or circumstance having, or which could reasonably be expected to have, a
material adverse effect on (i) the ability of such person to perform its
obligations under the Merger Agreement or to consummate the transactions
contemplated thereby or (ii) the financial condition, results of operations,
value or business of such person and its subsidiaries taken as a whole; except
for those changes, events and effects that (x) are caused by conditions
affecting the United States or world economy as a whole or affecting the
industry in which such entity competes as a whole, which conditions do not
affect such entity in a materially disproportionate manner, or (y) are related
to or result from announcement or pendency of the Merger or the Offer.
 
   Amendment to the Company Rights Agreement. Pursuant to the Merger
Agreement, the Company has agreed to amend the Rights Agreement to provide
that, among other things, the Offer and the execution and delivery of the
Merger Agreement (and any amendments thereto) and the Stockholder Agreements
(described below), and the consummation of the Merger and the transactions
contemplated thereby and by the Stockholder Agreements, will not cause (i)
Parent or Purchaser to constitute an "Acquiring Person" (as defined in the
Rights Agreement), (ii) a "Distribution Date," "Section 13 Event," "Triggering
Event," or "Shares Acquisition Date" (each as defined in the Rights Agreement)
to occur or (iii) the Rights to become exercisable pursuant to Section
11(a)(ii) thereof or otherwise. Such amendment has been effected by the
execution of a formal amendment to the Rights Agreement effective March 23,
1999 (the "Rights Amendment") by the Company and the Rights Agent, and the
filing with the SEC (and the effectiveness) of an amendment to the Company's
Registration Statement on Form 8-A/A on March 30, 1999 with respect to such
Rights Amendment.
 
   Conduct of Business of the Company. Except as provided for in the Merger
Agreement, during the period from the date of the Merger Agreement to the
Effective Time, the Company will, and will cause each of its subsidiaries to,
act and carry on its business only in the ordinary course of business
consistent with past practice and, to the extent consistent therewith, use
commercially reasonable efforts to preserve intact its current business
organizations, keep available the services of its current key officers and
employees and preserve the goodwill of those engaged in material business
relationships with the Company, and to that end, without limiting the
generality of the foregoing, the Company will not, and will not permit any of
its subsidiaries to, without the prior consent of Parent:
 
     (i)(A) declare, set aside or pay any dividends on, or make any other
  distributions (whether in cash, securities or other property) in respect
  of, any of its outstanding capital stock (other than, with respect to a
  subsidiary of the Company, to its corporate parent), (B) split, combine or
  reclassify any of its outstanding capital stock or issue or authorize the
  issuance of any other securities in respect of, in lieu of or in
  substitution for shares of its outstanding capital stock, or (C) purchase,

   No Solicitation; Acquisition Proposals. Pursuant to the Merger Agreement:
 
   (A) The Company has agreed that it will not, nor will it permit any of its
subsidiaries to, nor will it authorize (and will use its best efforts not to
permit) any officer, director or employee of, or any investment banker,
attorney or other advisor or representative of, the Company or any of its
subsidiaries to, (i) solicit or initiate, or intentionally encourage, directly
or indirectly, any inquiries relating to, or the submission of, any
Acquisition Proposal (as defined below), (ii) participate in any discussions
or negotiations regarding any Acquisition Proposal, or, in connection with any
Acquisition Proposal, furnish to any Person any information or data with
respect to or access to the properties of the Company or any of its
subsidiaries, or take any other action, to knowingly facilitate the making of
any proposal that constitutes, or may reasonably be expected to lead to, any
Acquisition Proposal or (iii) enter into any agreement with respect to any
Acquisition Proposal or approve or resolve to approve any Acquisition
Proposal; provided, that nothing contained in the Merger Agreement will
prohibit the Company or the Company's Board of Directors from (i) taking and
disclosing to the Company's stockholders a position with respect to a tender
or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2
promulgated under the Exchange Act, or (ii) making such disclosure to the
Company's stockholders as, in the good faith judgment of the Company's Board
of Directors, after consultation with outside counsel, is required under, or
is necessary to comply with, applicable law, provided that the Company may
not, except as described in subsection (C) of this "The Merger Agreement--No
Solicitation; Acquisition Proposals" section below, withdraw or modify, or
propose to withdraw or modify, its position with respect to the Offer or the
Merger or approve or recommend, or propose to approve or recommend any
Acquisition Proposal, or enter into any agreement with respect to any
Acquisition Proposal. The Company agreed that upon execution of the Merger
Agreement it would immediately cease any existing activities, discussions or
negotiations with any parties conducted theretofore with respect to any of the
foregoing. Notwithstanding the foregoing, prior to the time of acceptance of
Shares for payment pursuant to the Offer, the Company may furnish information
concerning its and/or its subsidiaries' business, properties or assets to any
person or group and may negotiate and participate in discussions and
negotiations with such person or group concerning an Acquisition Proposal,
provided that such person or group shall have entered into a confidentiality
agreement, the confidentiality provisions of which shall be no more favorable
to such third party than those provided for in the letter agreement dated
December 21, 1998 between Parent and the Company, if:
 
     (x) such Person or group has submitted a Superior Proposal (as defined
  below); and
 
     (y) in the opinion of the Company's Board of Directors such action is
  required to discharge the Board's fiduciary duties to the Company's
  stockholders under applicable law, determined only after consultation with
  independent legal counsel to the Company.
 
                                       8
<PAGE>
 
   The Company has agreed that it will promptly (but in no case later than 24
hours) notify Parent in writing of the existence of any proposal, discussion,
negotiation or inquiry received by the Company regarding any Acquisition
Proposal, and the Company will promptly communicate to Parent the terms of any
proposal, discussion, negotiation or inquiry which it may receive regarding
any Acquisition Proposal (and will promptly provide to Parent copies of any
written materials received by the Company in connection with such proposal,
discussion, negotiation or inquiry) and the identity of the party making such
proposal or inquiry or engaging in such discussion or negotiation. The Company
will promptly provide to Parent any non-public information concerning the
Company provided to any other person in connection with any Acquisition
Proposal which was not previously provided to Parent. The Company will keep
Parent informed of the status and details of any such Acquisition Proposal and
of any amendments or proposed amendments to any Acquisition Proposal and of
the status of any discussions or negotiations relating to any Acquisition
Proposal and will promptly (but in no case later than 24 hours) notify Parent
of any determination by the Company's Board of Directors that a Superior
Proposal has been made.
 
   (B) The Merger Agreement provides that except as described in this "The
Merger Agreement--No Solicitation; Acquisition Proposal" section, neither the
Board of Directors of the Company nor any committee thereof will (i) withdraw
or modify, or propose to withdraw or modify, in a manner adverse to Parent or
Purchaser, the approval or recommendation by the Board of Directors of the
Company of the Offer, the Merger Agreement or the Merger, (ii) approve or
recommend, or propose to approve or recommend, any Acquisition Proposal or
(iii) enter into any agreement with respect to any Acquisition Proposal.
Notwithstanding the foregoing or anything else in the Merger Agreement,
subject to compliance with the provisions described in this "The Merger
Agreement--No Solicitation; Acquisition Proposal" section, prior to the time
of acceptance for payment of Shares pursuant to the Offer, the Company's Board
of Directors may withdraw or modify its approval or recommendation of the
Offer, the Merger Agreement or the Merger, approve or recommend a Superior
Proposal, or enter into an agreement with respect to a Superior Proposal, in
each case at any time after the third business day following Parent's receipt
of written notice (including by facsimile) from the Company advising Parent
that the Board of Directors of Company has received a Superior Proposal which
it intends to accept, specifying the material terms and conditions of such
Superior Proposal and identifying the person making such Superior Proposal,
but only if the Company shall have caused its financial and legal advisors to
negotiate with Parent to make such adjustments to the terms and conditions of
this Agreement as would enable the Company to proceed with the transactions
contemplated hereby on such adjusted terms.
 
   (C) The Merger Agreement provides that nothing described in this "The
Merger Agreement--No Solicitation; Acquisition Proposal" section, and no
action taken by the Board of Directors of the Company pursuant to the matters
described in this "The Merger Agreement--No Solicitation; Acquisition
Proposal" section, will (i) permit the Company to enter into any agreement
providing for any transaction contemplated by an Acquisition Proposal for as
long as the Merger Agreement remains in effect or (ii) affect in any manner
any other obligation of the Company under the Merger Agreement.
 
   (D) For purposes of the Merger Agreement, "Acquisition Proposal" means any
bona fide offer, proposal or other indication of interest regarding any of the
following (other than the transactions provided for in the Merger Agreement
involving the Company): (i) any merger, consolidation, share exchange,
recapitalization, business combination or other similar transaction involving
the Company or any of its subsidiaries; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of a significant portion of
the assets of the Company and its subsidiaries, taken as a whole, in a single
transaction or series of related transactions (other than sales of inventory
or used equipment in the ordinary course of business); (iii) any purchase of,
or tender offer or exchange offer for, 20% percent or more of the outstanding
shares of capital stock of Company by any person or the filing of a
registration statement under the Securities Act of 1933, as amended, in
connection therewith; or (iv) any public announcement of a proposal, plan or
intention to do any of the foregoing or any agreement to engage in any of the
foregoing. For purposes of the Merger Agreement, "Superior Proposal" means an
unsolicited Acquisition Proposal on terms which the Board of Directors of the
Company determines in good faith to be more favorable to the Company's
stockholders than the Offer and the Merger (based on advice
 
                                       9
<PAGE>
 
of the Company's independent financial advisor that the value of the
consideration provided for in such proposal is superior to the value of the
consideration provided for in the Offer and the Merger); for which financing,
to the extent required, is then committed or which, in the good faith
reasonable judgment of the Board of Directors of the Company (based on advice
from the Company's independent financial advisor) is reasonably capable of
being financed by such third party provided that the Company's Board of
Directors has also, among other things, duly considered the timing of such
Acquisition Proposal and the likelihood that such Acquisition Proposal will be
consummated.
 
   Employee Benefit Matters. The Merger Agreement provides that Parent will,
and will cause its subsidiaries (including the Surviving Corporation) to,
honor and provide for payment of all accrued obligations and benefits under
all Company Plans and employment or severance agreements which have been
disclosed in the Merger Agreement between Company and persons who are or had
been employees of the Company or any of its subsidiaries at or prior to the
Effective Time ("Covered Employees"), all in accordance with their respective
terms and provide Covered Employees who remain in the employ of the Company or
any of its subsidiaries with employee benefits that are reasonably comparable
to the employee benefits provided to similarly situated employees of Parent or
any such subsidiary who are not Covered Employees subject to certain
restrictions and limitations described in the Merger Agreement. To the extent
that Covered Employees are included in any benefit plan of Parent or its
subsidiaries, Parent agrees that the Covered Employees will receive credit
under such plan (other than any such plan providing for sabbaticals) for
service prior to the Effective Time with the Company and its subsidiaries to
the same extent such service was counted under similar plans of the Company
for purposes of eligibility, vesting, eligibility for retirement (but not for
benefit accrual) and, with respect to vacation, disability and severance,
benefit accrual. To the extent that Covered Employees are included in any
medical, dental or health plan other than the plan or plans they participated
in at the Effective Time, Parent has agreed that any such plans shall not
include pre-existing condition exclusions, except to the extent such
exclusions were applicable under the similar plan of the Company at the
Effective Time, and shall provide credit for any deductibles and co-payments
applied or made with respect to each Covered Employee in the calendar year of
the change. Except as set forth above, nothing in the Merger Agreement shall
prevent Parent or the Surviving Corporation from amending or terminating any
plan of the Company in accordance with its terms.
 
   Indemnification; Directors' and Officers' Insurance. The Merger Agreement
provides that for a period of four years after the Effective Time, the
provisions with respect to indemnification set forth in the certificate of
incorporation and by-laws of Purchaser as in effect on the date of the Merger
Agreement shall not be amended, repealed or otherwise modified in any manner
that would adversely affect the rights thereunder of individuals who at any
time prior to the Effective Time were directors or officers of the Company in
respect of actions or omissions occurring at or prior to the Effective Time
(including without limitation the transactions contemplated by the Merger
Agreement), unless such modification is required by law.
 
   In addition, from and after the Effective Time, Parent will, or will cause
the Surviving Corporation to, indemnify, defend and hold harmless each person
who as of the date of the Merger Agreement is, or has been at any time prior
to the date of the Merger Agreement or who becomes prior to the Effective
Time, an officer or director of the Company (the "Indemnified Parties")
against all losses, claims, damages, costs, expenses (including reasonable
attorneys' fees and expenses), liabilities or judgments or amounts that are
paid in settlement with the approval of the indemnifying party (which approval
shall not be unreasonably withheld) incurred in connection with any threatened
or actual action, suit or proceeding based in whole or in part on or arising
in whole or in part out of the fact that such person is or was a director or
officer of the Company ("Indemnified Liabilities"), including all Indemnified
Liabilities based in whole or in part on, or arising in whole or in part out
of, the Merger Agreement or the transactions contemplated thereby, in each
case, to the full extent that a corporation is permitted under the DGCL to
indemnify its own directors or officers, as the case may be. The rights to
indemnification under the Merger Agreement will continue in full force and
effect for a period of four years from the Effective Time; provided, however,
that all rights to indemnification in respect of any Indemnified Liabilities
asserted or made within such period shall continue until the disposition of
such Indemnified Liabilities.
 
                                      10
<PAGE>
 
   Finally, for a period of two years after the Effective Time, Parent will
cause to be maintained in effect policies of directors' and officers'
liability insurance, for the benefit of those persons who are covered by the
Company's directors' and officers' liability insurance policies at the
Effective Time, providing coverage with respect to matters occurring prior to
the Effective Time that is at least equal to the coverage provided under the
Company's current directors' and officers' liability insurance policies, to
the extent that such liability insurance can be maintained at an annual cost
to Parent not greater than 150% of the premium for the current Company
directors' and officers' liability insurance; provided that if such insurance
cannot be so maintained at such cost, Parent will maintain as much of such
insurance as can be so maintained at a cost equal to 150% of the current
annual premiums of the Company for such insurance.
 
   Conditions to Each Party's Obligation to Effect the Merger. The Merger
Agreement provides that the respective obligation of each party thereto to
effect the Merger will be subject to the satisfaction or written waiver on or
prior to the Closing Date of the following conditions:
 
     (a) Purchaser shall have accepted for payment and paid for all Shares
  validly tendered in the Offer and not withdrawn; provided, however, that
  neither Parent nor Purchaser may invoke this condition if Purchaser shall
  have failed to purchase Shares so tendered and not withdrawn in violation
  of the terms of the Merger Agreement or the Offer.
 
     (b) The Merger Agreement shall have been adopted by the affirmative vote
  of the holders of the requisite number of shares of capital stock of the
  Company if such vote is required pursuant to the Company's Certificate of
  Incorporation, the DGCL or other applicable law.
 
     (c) No temporary restraining order, preliminary or permanent injunction
  or other order issued by any court of competent jurisdiction or other legal
  restraint or prohibition preventing the consummation of the Merger shall be
  in effect; provided, however, that prior to invoking this condition, the
  party so invoking this condition shall have complied with its commercially
  reasonable efforts and filing obligations and the parties to the Merger
  Agreement shall have used commercially reasonable efforts to lift or remove
  such order, injunction, restraint or prohibition.
 
     (d) All necessary waiting periods under the HSR Act applicable to the
  Merger shall have expired or been earlier terminated.
 
   Termination. The Merger Agreement may be terminated and the Merger
contemplated by the Merger Agreement may be abandoned at any time prior to the
Effective Time, whether before or after approval of matters presented in
connection with the Merger by the stockholders of the Company:
 
     (a) By the mutual written consent of Parent and the Company; provided,
  however, that if Parent shall have a majority of the directors of the
  Company, such consent of the Company may only be given if approved by the
  Continuing Directors.
 
     (b) By either of Parent or the Company if (i) a statute, rule or
  executive order shall have been enacted, entered or promulgated prohibiting
  the transactions contemplated by the Merger Agreement on the terms
  contemplated by the Merger Agreement or (ii) any governmental entity shall
  have issued an order, decree or ruling or taken any other action (which
  order, decree, ruling or other action the parties to the Merger Agreement
  shall use their commercially reasonable efforts to lift), in each case
  permanently restraining, enjoining or otherwise prohibiting the
  transactions contemplated by the Merger Agreement and such order, decree,
  ruling or other action shall have become final and non-appealable.
 
     (c) By either of Parent or the Company if the consummation of the Offer
  shall not have occurred on or before July 31, 1999; provided, however, that
  the party seeking to terminate the Merger Agreement pursuant to this
  provision (c) shall not have breached in any material respect its
  obligations under the Merger Agreement;
 
                                      11
<PAGE>

       (i) if the Company has entered into an agreement with respect to a
    Superior Proposal or the Company or the Board of Directors of the
    Company has approved or recommended a Superior Proposal in accordance
    with and provided that the Company has complied with all provisions of
    the Merger Agreement, including the notice provisions therein, and that
    it simultaneously terminates the Merger Agreement and makes
    simultaneous payment to the Parent of the Termination Fee and the
    Expenses (as defined in "The Merger Agreement--Fees and Expenses"
    section below); or
 
       (ii) if Parent or Purchaser shall have terminated the Offer or the
    Offer expires without Parent or Purchaser, as the case may be,
    purchasing any Shares pursuant thereto; provided that the Company may
    not terminate the Merger Agreement pursuant to this provision if the
    Company is in material breach of the Merger Agreement; or
 
       (iii) if Parent, Purchaser or any of their affiliates shall have
    failed to commence the Offer on or prior to five business days
    following the date of the initial public announcement of the Offer;
    provided, that the Company may not terminate the Merger Agreement
    pursuant to this provision if the Company is in material breach of the
    Merger Agreement; or
 
       (iv) if there shall be a material breach by either Parent or
    Purchaser of any of their representations, warranties, covenants or
    agreements contained in the Merger Agreement, except where such breach
    does not have a material adverse effect on the ability of Parent or
    Purchaser to consummate the Offer or the Merger.
 
     (e) By Parent or Purchaser:
 
       (i)(A) if, prior to the purchase of the Shares pursuant to the

    approval or recommendation of the Offer, the Merger Agreement or the
    Merger or shall have recommended or approved, or announced a neutral
    position with respect to, an Acquisition Proposal or upon request of
    Parent, shall fail to reaffirm its approval and recommendation of the
    Offer, the Merger Agreement, or the Merger; or
 
       (B) if there shall have been a material breach by the Company of any
    provision of the Merger Agreement relating to the prohibition of
    solicitation of Acquisition Proposals; or
 
       (ii) if the Offer has expired or terminated without Parent or
    Purchaser purchasing any Shares thereunder and, pursuant to the
    "Conditions to the Offer" described below and the Merger Agreement, the
    Purchaser is neither required to accept and pay for the Shares tendered
    in the Offer nor extend the expiration date of the Offer, provided that
    Parent or Purchaser may not terminate the Merger Agreement pursuant to
    this provision if Parent or Purchaser is in material breach of the
    Merger Agreement; or
 
       (iii) if, due to an occurrence that if occurring after the
    commencement of the Offer would result in a failure to satisfy any of
    the conditions set forth in the "Conditions to the Offer" described
    below which occurrence is incapable of being cured or remediated prior
    to the initial expiration date of the Offer, Parent, Purchaser or any
    of their affiliates shall have failed to commence the Offer on or prior
    to five business days following the date of the initial public
    announcement of the Offer, provided that Parent or Purchaser may not
    terminate the Merger Agreement pursuant to this provision if Parent or
    Purchaser is in material breach of the Merger Agreement; or
 
       (iv) if any Person or "group" (as defined in Section 13(d)(3) of the
    Exchange Act), other than Parent, Purchaser or their affiliates or any
    group of which any of them is a member, shall have acquired beneficial
    ownership (as determined pursuant to Rule 13d-3 promulgated under the
    Exchange Act) of 20% or more of the Shares; or
 
       (v) if there shall be a breach by the Company of any of its
    representations or warranties contained in the Merger Agreement
    (without reference to any "Material Adverse Effect" or "materiality"
 
                                      12
<PAGE>
 
    qualifications contained therein) which breach causes a Material
    Adverse Effect on the Company and is incapable of being cured prior to
    the twentieth business day following the initial expiration date of the
    Offer or there shall be a material breach by the Company of any of its
    covenants or agreements contained in the Merger Agreement.
 
   Fees and Expenses. The Merger Agreement provides that except as provided in

Offer, the Merger, the Merger Agreement and the transactions contemplated by
the Merger Agreement shall be paid by the party incurring such fees or
expenses, whether or not the Offer or the Merger is consummated.
 
   The Merger Agreement provides that if (x) Parent or Purchaser terminates
the Merger Agreement pursuant to provision (e)(i) described in "The Merger
Agreement--Termination" section above, or (y) the Company terminates the
Merger Agreement pursuant to provision (d)(i) described in "The Merger
Agreement--Termination" section above, then in each case, the Company shall
pay, or cause to be paid to Parent, at the time of termination, an amount
equal to $2,870,000 (the "Termination Fee") and an amount equal to Parent's
and Purchaser's actual and reasonably documented out-of-pocket expenses
incurred by Parent or Purchaser in connection with the Offer, the Merger, the
Merger Agreement and the consummation of the transactions contemplated by the
Merger Agreement up to a maximum expense reimbursement amount of $718,000 (the
"Expenses"). In addition, if the Merger Agreement is terminated by Parent or
Purchaser pursuant to provision (e)(ii) described in "The Merger Agreement--
Termination" section above solely as a result of the failure of the Minimum
Condition or by the Company pursuant to provision (d)(ii) described in "The
Merger Agreement--Termination" section above and, in each case at the time of
such termination, Parent is not in material breach of the Merger Agreement and
there has been previously publicly announced, and not withdrawn, an
Acquisition Proposal, and, if the Company shall thereafter, within nine months
after such termination, enter into an agreement with respect to such
Acquisition Proposal, then the Company shall pay the Termination Fee
concurrently with entering into any such agreement. If the Merger Agreement is
terminated by Parent or Purchaser pursuant to provision (e)(v) described in
"The Merger Agreement--Termination" section above, then the Company shall pay
Parent the Expenses. Any payments required to be made pursuant to this
provision shall be made by wire transfer of same day funds to an account
designated by Parent.
 
Conditions to the Offer
 
   The Merger Agreement provides that, notwithstanding any other provision of
the Offer and subject to the terms of the Merger Agreement, Purchaser shall
not be required to accept for payment or, subject to any applicable rules and
regulations of the SEC, pay for, and may delay the acceptance for payment of
or the payment for, any tendered Shares, and may amend the Offer consistent
with the terms of the Merger Agreement or terminate the Offer and not accept
for payment any tendered Shares, if (i) there shall not have been validly
tendered and not withdrawn prior to the expiration of the Offer such number of
Shares which, when added to the Shares, if any, beneficially owned by Parent
or Purchaser, would constitute at least a majority of the Shares outstanding
on a fully-diluted basis on the date of purchase ("on a fully-diluted basis"
meaning, as of any date, the number of Shares outstanding, together with the
Shares which the Company may be required to issue pursuant to warrants,
options or obligations outstanding at that date under employee stock purchase
or similar benefit plans or otherwise, whether or not vested or then
exercisable) (the "Minimum Condition"), (ii) any applicable waiting period
under the HSR Act has not expired or been terminated, or (iii) at any time on
or after the date of the Merger Agreement and prior to the Expiration Date,
any of the following events shall occur and be continuing and shall not have
resulted from the breach by Parent or Purchaser of any of their obligations
under the Merger Agreement:
 
     (a) there shall be pending any suit, action or proceeding brought by any
  third party that has a high likelihood of success on the merits or by any
  Governmental Entity (as defined in the Merger Agreement) before any court

which in the sole good faith judgment of Parent or Purchaser, in any such
case, and regardless of the circumstances (including any action or inaction by
Parent or Purchaser) giving rise to such condition makes it inadvisable to
proceed with the Offer and/or with such acceptance for payment of or payments
for Shares.
 
   The foregoing conditions are for the sole benefit of Parent and Purchaser
and may (except for the Minimum Condition) be waived by Parent or Purchaser,
in whole or in part, at any time and from time to time, in the sole discretion

exercise any of the foregoing rights shall not be deemed a waiver of any right
and each such right shall be deemed an ongoing right which may be asserted at
any time and from time to time.
 
Stockholder Agreements
 
   The following is a summary of certain provisions of the Stockholder
Agreements. This summary is not a complete description of the terms and
conditions of the Stockholder Agreements and is qualified in its entirety by
reference to the full text of the forms of Stockholder Agreements filed with
the SEC as Exhibits 99.2, 99.3 and 99.4 to this Schedule 14D-9 and
incorporated herein by reference. Capitalized terms not otherwise defined
below shall have the meanings set forth in the Stockholder Agreements.
 
   As a condition and inducement to Parent's entering into the Merger
Agreement and incurring the liabilities therein, all of the Company's then-
current executive officers and directors and certain entities related to
Advent International Corporation (collectively, "Advent") and Cisco Systems,
Inc. ("Cisco") (for purposes of this "Stockholder Agreements" section, the
aforementioned entities shall be referred to as the "Stockholders"), who
collectively have voting power and dispositive power with respect to an
aggregate of 1,171,068 Shares and hold Options to acquire 854,050 Shares,
concurrently with the execution and delivery of the Merger Agreement entered
into the Stockholder Agreements with Parent. Pursuant to the Stockholder
Agreements, the Stockholders have agreed, among other things, to grant Parent
an irrevocable proxy to vote the Shares covered by the Stockholder Agreements
(collectively, the "Subject Shares") in favor of the Merger and against any
other Acquisition Proposal (as defined in the Merger Agreement). The
Stockholders have also granted to Parent an option to purchase the Subject
Shares at an option price of $7.00 per Subject Share (or any higher price
offered by Parent or a subsidiary of Parent to the stockholders of the Company
generally) during the "Option Period". With respect to the option granted to
Parent by the directors and executive officers of the Company, "Option Period"
means the period between March 23, 1999 and the earlier of (i) 120 days after
the purchase of Shares pursuant to the Offer or (ii) the date that the Merger
Agreement is terminated for any reason. With respect to the option granted to
Parent by Advent, "Option Period" means the period between March 23, 1999 and
the earlier of (i) 120 days after the purchase of Shares pursuant to the Offer
or (ii) 120 days after the date on which the Merger Agreement is terminated
for any reason, provided, however, that such option shall terminate (x) if the
Merger Agreement is terminated by the Company because of a material breach by
Parent or Purchaser and at the time of such termination the Company is not in
breach of the Merger Agreement, and (y) if the Merger Agreement is terminated
by the Company or because the condition requiring termination of all necessary
waiting periods under the HSR Act is incapable of being fulfilled. With
respect to the option granted by Cisco, "Option Period" means the period
between March 23, 1999 and the earlier of (i) 120 days after the purchase of
Shares pursuant to the Offer or (ii) 120 days after the date on which the
Merger Agreement is terminated (A) pursuant to provision (d)(i) as described
above in "The Merger Agreement--Termination Section" or (B) pursuant to
provision (e)(i) as described in "The Merger Agreement--Termination Section"
or (iii) 30 days after the date on which the Merger Agreement is terminated
pursuant to provision (e)(v) as described in "The Merger Agreement--
Termination" section, or (iv) the date on which the Merger Agreement is
terminated other than for reasons described in clauses (ii) or (iii) of this
sentence.
 
   During the period from the date of the Stockholder Agreements through and
including the earlier of (i) the Effective Time and (ii) the end of the
relevant Option Period, each Stockholder has agreed not to: (A) except for the
tender of Subject Shares in the Offer, offer for sale, sell, transfer, tender,
pledge, encumber, assign or otherwise dispose of, or enter into any contract,
option or other arrangement, understanding, or consent to do so; (B) grant any
proxies (other than proxies relating to the election of management's slate of
directors at an annual
 
                                      15
<PAGE>
 
meeting of the Company's stockholders, and other routine matters which would
not require the filing of a preliminary proxy statement under Rule 14a-6(a) of
the Exchange Act), or powers of attorney, deposit any of the Subject Shares
into a voting trust or enter into a voting agreement with respect to any of
the Subject Shares; or (C) take any action that would make any representation
or warranty contained in the applicable Stockholder Agreement untrue or
incorrect or have the effect of impairing the ability of such Stockholder to
perform the Stockholder's obligations under such Stockholder Agreement or
preventing or delaying the consummation of any of the transactions
contemplated by the Stockholder Agreement and Merger Agreement.
Notwithstanding the foregoing, Advent will have the right (i) to transfer
Subject Shares to an affiliate, as long as, before any such transfer, such
affiliate enters into a written agreement (an "Acknowledgement Agreement")
with Parent whereby such affiliate agrees to be bound by all of the terms and
provisions of Advent's Stockholder Agreement with respect to the Subject
Shares received by such affiliate, (ii) prior to the exercise by Parent of its
option and following the termination of the Merger Agreement (other than a
termination which requires the payment of the Termination Fee), to sell
Subject Shares in open market transactions, provided that any such sale shall
not limit or relieve Advent of its obligation to deliver Subject Shares to
Parent in the event Parent exercises the option to purchase such Subject
Shares, and (iii) transfer or sell Subject Shares to one or more third parties
in privately-negotiated transactions as long as each such third party enters
into an Acknowledgment Agreement with Parent.
 
   Each of the directors and executive officers of the Company entering into a
Stockholder Agreement has also agreed, subject to certain exclusions relating
to indemnification and employment matters, to unconditionally release, as of
the Effective Time, any and all claims and causes of action that such
directors and officers may have against the Company or any of its subsidiaries
or any present or former director, officer, employee or agent of the Company
or any of its subsidiaries (collectively, the "Released Parties") resulting
from any act, omission or occurrence prior to the Effective Time. Advent has
agreed to unconditionally release, as of the Effective Time, any and all
claims and causes of action that Advent may have against the Released Parties
resulting from any act, omission or occurrence prior to the Effective Time.
Cisco has agreed to unconditionally release, as of the Effective Time, any and
all claims and causes of action that Cisco may have against the Released
Parties resulting from any alleged breach of fiduciary duty by any officer or
director of the Company occurring prior to the Effective Time; provided,
however, that such release will not apply to any currently effective contract
or agreement between Cisco and the Company or any claim or cause of action
arising therefrom.
 
   Each Stockholder has agreed that, in the capacity as a stockholder, it will
not respond to any inquiries or the making of any proposal by any person or
entity (other than Parent or any affiliate of Parent) concerning any business
combination, merger, tender offer, exchange offer, sale of assets, sale of
shares of capital stock or debt securities or similar transactions involving
the Company or any subsidiary, division or operating or principal business
unit of the Company. If any Stockholder, in the capacity as a stockholder,
receives any such inquiry or proposal, then the Stockholder has agreed to
promptly inform Parent of the existence thereof. Each Stockholder, in the
capacity as a stockholder, has agreed to immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any
parties previously conducted with respect to any of the foregoing.
 
The Exclusivity Agreement
 
   The following is a summary of certain provisions of the Exclusivity
Agreement. This summary is not a complete description of the terms and
conditions of the Exclusivity Agreement and is qualified in its entirety by
reference to the full text of the Exclusivity Agreement filed with the SEC as
Exhibit 99.8 to this Schedule 14D-9 and incorporated herein by reference.
Capitalized terms not otherwise defined below shall have the meanings set
forth in the Exclusivity Agreement.
 
   On March 16, 1999, the Company and Parent entered into an exclusivity
agreement ("Exclusivity Agreement") pursuant to which the Company agreed to,
and to use all reasonable efforts to cause all of its and its subsidiaries'
affiliates, officers, directors, employees, agents and representatives to,
discontinue any solicitation efforts with respect to any potential acquisition
of the Company with anyone other than Parent, until the earlier of (a) 6:00
p.m. California time on March 25, 1999, or (b) the execution of a definitive
agreement governing the terms and conditions of the potential acquisition of
the Company by Parent ("Exclusivity
 
                                      16
<PAGE>
 
Period"). The Company also agreed during the Exclusivity Period not to enter
into discussions or negotiations with any other person concerning an
acquisition proposal or to endorse such other proposal and to notify Parent
immediately if, during the Exclusivity Period, the Company received certain
types of expressions of interest from persons other than Parent.
 
   Pursuant to the Exclusivity Agreement, Parent agreed that for a period of
one year from the date of the Exclusivity Agreement, it will not, directly or
indirectly, solicit for employment or attempt to hire or recruit any employee
of the Company (or any subsidiary thereof) with whom Parent has had contact or
who became known to Parent in connection with Parent's consideration of a
potential acquisition. However, Parent will not be deemed to have breached or
violated this restriction solely (a) as a result of generic employment
advertising by Parent (including, without limitation, "open position" and
similar listings in Parent's various World Wide Web pages), (b) as a result of
the efforts of an executive recruitment or similar firm generally engaged to
recruit employees for Parent (without targeting of the Company or its specific
employees) or (c) if any employee of the Company (or any subsidiary thereof)
approaches and obtains employment with Parent after the date of the
Exclusivity Agreement solely as a result of any advertising or recruitment
effort contemplated in clause (a) or (b) above.
 
Item 4. The Solicitation or Recommendation.
 
   (a) Recommendation of the Company Board of Directors.
 
   The Company Board of Directors has unanimously (i) determined that the
Merger Agreement and the transactions contemplated thereby, including each of
the Offer and the Merger, are fair to and in the best interests of the Company
and its stockholders, (ii) approved and adopted the Merger Agreement and the
transactions contemplated thereby, and (iii) resolved to recommend that the
stockholders of the Company accept the Offer and tender their Shares pursuant
to the Offer and approve and adopt the Merger Agreement and approve the
transactions contemplated thereby.
 
   A letter to the Company's stockholders communicating the Company's
recommendation and a press release announcing the execution of the Merger
Agreement are filed with this Schedule 14D-9 as Exhibits 99.6 and 99.5,
respectively, and are incorporated herein by reference in their entirety.
 
   (b) Background of the Offer; Reasons for the Recommendation.
 
 Background of the Offer.
 
   On several occasions during September 1998, representatives of Broadview
International, LLC, Parent's financial advisor ("Broadview"), contacted Mr.
Augustus J. Berkeley, President and Chief Executive Officer of the Company, to
discuss the possibility of a merger of the Company with a Broadview client. On
September 29, 1998, general information regarding Parent and Company was
exchanged by Parent and Company through Broadview. On October 6, 1998, Mr. Ron
Hardy, Vice President, Business Development, of Parent's Systems Management
Group, met with Mr.  Berkeley and Mr. James Barth, Chief Financial Officer of
the Company, at the Hilton Hotel in Newark, California to explore on a
preliminary basis the possibility of such an acquisition. This meeting did not
lead to any agreements or understandings. On December 14, 1998, Mr. Hardy
called Mr. Berkeley to set up a meeting regarding a potential high level
business review meeting and related logistics. On December 16, 1998, the
Company's Board met and reviewed with Mr. Berkeley the extent of the Company's
discussions with Parent. On December 21, 1998, in anticipation of a business
review meeting between Parent and the Company, Parent and the Company entered
into a confidentiality agreement for the purpose of permitting Parent to
review certain nonpublic information relating to the Company in connection
with Parent's evaluation of a possible acquisition.
 
   On December 21, 1998, Mr. Berkeley, all then-current executive officers of
the Company, and Mr. Christopher Schember, a business development advisor to
the Company, met with Mr. Hardy, Mr. Mike Harvey, President of Parent's
Systems Management Group, Mr. Randy Davis, President of Parent's Network
 
                                      17
<PAGE>
 
Management Division and Richard Vieira, a representative from Broadview, at
the Courtyard Marriott in Fremont, California to discuss a potential
combination between the Company and Parent. The participants discussed the
Company's products, historical and projected financial information (but only
such financial information as the Company has historically shared with the
financial community). No proprietary information was disclosed by the Company
to Parent at this meeting including information relating to the Company's
sales pipeline, customer names, organizational charts, or prospects (other
than already-disclosed projected financial information).
 
   On December 23, 1998, Mr. Geno P. Tolari, Executive Vice President and
Chief Operating Officer of Parent, held discussions with Mr. Berkeley at Mr.
Tolari's home in Pleasanton, California about setting up a more intensive two-
day business due diligence session. At such meeting and subsequently, Mr.
Berkeley requested Mr. Tolari to provide the Company with an indication of the
price range that Parent would be willing to offer for the Company. Mr.
Berkeley also informed Mr. Tolari that he did not believe that the Company's
current stock price represented the real value of the Company, and that if
Parent was merely interested in a bargain price, then the Company would not be
interested in continuing discussions with Parent. Mr. Tolari advised
Mr. Berkeley that Parent would not be in a position to give a price indication
until after the two-day business review, but assured Mr. Berkeley that if the
follow-on discussion went as well as the December 21, 1998 discussions, that
the proposed price would be fair.
 
   Also on December 23, 1998, Parent provided the Company with an extensive
due diligence list. During the month of January the Company reviewed and
compiled basic information relating to such list.
 
   In early February 1999, Mr. Hardy called Mr. Berkeley to set up a meeting
for a detailed business review meeting between the Company and Parent for
February 5 and 6, 1999.
 
   On February 3, 1999, Mr. Berkeley and Mr. Barth met with representatives of
Hambrecht and Quist LLC, the Company's financial advisor ("H&Q"), and Mr.
Schember to discuss planning for and flow of information from the Company to
Parent and the upcoming meeting on February 5 and 6, 1999 with Parent.
 
   On February 5 and 6, 1999, senior executives of Parent and its financial
advisor met with senior executives of the Company at the Courtyard Marriott in
Fremont, California for the purpose of conducting a detailed business review
of the Company, including a review of the Company's business, operations, and
technology, in order to assess the strategic opportunities of a business
combination with the Company. No information regarding the Company's sales
pipeline, customer names, organizational charts, or prospects (other than
already-disclosed projected financial information) was disclosed by the
Company to Parent at this meeting.
 
   On February 15, 1999, Parent's senior management met internally to consider
the results of its preliminary business review of the Company and the
strategic opportunities presented by an acquisition of the Company. Parent's
senior management decided to pursue an acquisition of the Company but
determined that Parent would request the Company to first seek a waiver from
Cisco Systems, Inc. ("Cisco") of certain provisions of a Stock Purchase
Agreement between the Company and Cisco, dated December 12, 1996 (the "Cisco
Agreement"), pursuant to which, among other things, Cisco was entitled to
receive 20 days prior notice before the Company could accept an acquisition
proposal (the "Acquisition Notice Provision").
 
   On February 16, 1999, representatives of Broadview contacted H&Q, to advise
H&Q that Parent was interested in pursuing an acquisition of the Company but
would require that the Company first obtain a waiver from Cisco of the
Acquisition Notice Provision. Broadview also advised H&Q that Parent, although
not making a formal offer, would be prepared to discuss a transaction at a
price at least equal to $5.50 per Share. On February 16, 1999, Mr. Harvey had
dinner with Mr. Berkeley to discuss Parent's continued interest in the
Company, Mr. Harvey acknowledged his understanding that management of the
Company would not support a transaction unless it was fair to the Company's
stockholders and Mr. Berkeley indicated that he would discuss pursuit of such
waiver from Cisco with the Company's Board.
 
 
                                      18
<PAGE>
 
   On February 18, 1999, representatives of H&Q met with the Company's Board
and discussed Parent's interest in the Company at a price level of $5.50 per
Share. Parent indicated that the making of an offer would be conditioned on
the Company's obtaining a waiver from Cisco of its right to be notified of
transactions such as that considered by Parent. The Board authorized the
Company's management to seek a waiver from Cisco of the Acquisition Notice
Provision and to negotiate the transaction presented by H&Q at a $7.50 price
per Share. The Company's Board also directed H&Q to identify other companies
that would be interested in acquiring the Company. Thereafter, the Company
sought to obtain such a wavier from Cisco and, on March 3, 1999, the Company
and Cisco entered into a letter agreement which terminated certain provisions
of the Cisco Agreement, including the Acquisition Notice Provision.
 
   On March 6, 1999, Mr. Berkeley telephoned Mr. Tolari and informed him that
the Company was not interested in proceeding with a transaction at the $5.50
per Share level. Mr. Berkeley informed Mr. Tolari that the Company's Board
directed him to discuss a price of $7.50 per Share, and that the Company was
not presently prepared to consider a price that was lower than $7.50.
 
   Between March 6 and March 10, 1999, Mr. Sterling L. Williams, President and
Chief Executive Officer of Parent, and Mr. Tolari had several telephone
conversations with Mr. Berkeley in an effort to set up a meeting. Because of
scheduling difficulties in setting up the meeting, on March 11, 1999, Mr.
Williams telephoned Mr. Berkeley to advise him that Parent was prepared to
proceed with a transaction at a price of $7.00 per Share, subject to
satisfactory completion of due diligence and negotiation of other acceptable
terms and conditions. Mr. Williams requested that Mr. Berkeley respond by the
close of business on March 12, 1999. Mr. Berkeley stated that he would consult
with the Company's Board and called the Company's Board to a meeting for the
following day.
 
   On March 12, 1999, the Company's Board met with representatives of H&Q to
discuss Parent's offer. H&Q advised the Board that a $7.00 per Share offer
represented a substantial premium to the historical trading range of the
Company's common stock and that in H&Q's view the risks of attempting to
negotiate a higher price outweighed the benefits. H&Q also advised the Company
on the status of its contacts with other companies with respect a potential
acquisition. The Board then authorized Company's management to negotiate the
transaction as previously presented, at $7.00 per Share. Following the Board
meeting, Mr. Berkeley advised Mr. Tolari that the Company Board had authorized
the Company's management to engage in discussions with Parent with respect to
a potential acquisition of the Company by Parent at a price of $7.00 per
Share.
 
   Late in the day on March 12, 1999, Parent furnished to the Company, and
Broadview furnished to H&Q, a summary proposal outlining the principal terms
and conditions of a potential acquisition of the Company by Parent.
 
   On March 15, 1999, following its review of the summary proposal, the
Company advised Parent that it was prepared to begin negotiations of
definitive agreements and that, subject to the confirmation of the Company's
Board, Parent's representatives could conduct a detailed due diligence review
of the Company commencing on March 17, 1999.
 
   During the afternoon of March 15, 1999, Parent transmitted to
representatives of the Company a letter agreement providing that the Company
would negotiate exclusively with Parent for a limited period of time (the
"Exclusivity Letter"), a draft Merger Agreement, a draft form of Stockholder
Agreement and a due diligence request list. Parent advised the Company that
Parent would require Cisco, certain limited partnerships controlled by Advent
International Corp. (collectively "Advent") and the executive officers and
directors of the Company to sign Stockholder Agreements granting Parent an
option to purchase their Shares at a price of $7.00 per Share in cash and
grant Parent a proxy with respect to such Shares.
 
   On March 16, 1999, the Company informed the Board of the status of the
negotiations, and the Board authorized the Company's officers to negotiate,
execute and deliver the Exclusivity Letter. Commencing on March 16, 1999,
representatives of Parent and the Company and their respective counsel began
negotiating the
 
                                      19
<PAGE>
 
Exclusivity Letter, the draft Merger Agreement and the form of Stockholder
Agreement. On the evening of March 16, 1999, Parent and the Company executed
the Exclusivity Letter which provided, among other things, that until the
earlier of 6:00 p.m., California time, on March 25, 1999 and the execution of
a definitive agreement, the Company and its affiliates and representatives
would discontinue any solicitation efforts, discussions or negotiations with
respect to an acquisition proposal by any person other than Parent and would
not solicit or facilitate other proposals to acquire the Company. In addition,
the Company agreed to notify Parent if it received any acquisition proposal
providing aggregate consideration for all of the Company's outstanding Shares
having a value in excess of $7.00 per Share.
 
   Commencing on March 17, 1999, representatives of Parent conducted an
intensive due diligence review of the Company. The negotiation of the Merger
Agreement and the Stockholder Agreements and Parent's due diligence review
continued until March 23, 1999.
 
   On March 18, 1999, Cisco and Advent were furnished a draft of the form of
Stockholder Agreement and on March 19, 1999 Parent began negotiating the terms
of the Stockholder Agreements with representatives of Cisco and Advent, which
negotiations continued until March 23, 1999.
 
   On March 19, 1999, the Company's Board met to review final unresolved
issues relating to the Merger Agreement and Stockholder Agreements.
 
   On March 23, 1999, the Company's Board met, reviewed and discussed the
Merger Agreement and Stockholder Agreements, H&Q delivered its opinion to the
Board that the Offer Consideration per Share was fair to the stockholders of
the Company, from a financial point of view, and the Board voted unanimously
to approve the Merger Agreement and other transactions contemplated thereby,
and to recommend that the Company's stockholders tender their Shares in
response to Parent's tender offer. On March 23, 1999, the Merger Agreement was
executed and delivered by Parent, Purchaser and the Company, and Parent,
Purchaser and the Stockholders entered into the Stockholder Agreements. On
March 24, 1999, Parent and the Company issued a joint press release announcing
the execution of the Merger Agreement. On March 30, 1999, pursuant to the
terms of the Merger Agreement, Parent and Purchaser commenced the Offer.
 
   Factors Considered by the Board of Directors. In approving the Offer, the
Merger Agreement and the transactions contemplated thereby, and recommending
that all stockholders tender their Shares pursuant to the Offer, the Company
Board of Directors considered a number of factors, including:
 
     (1) the financial and other terms of the Offer, the Merger Agreement and
  the related Stockholder Agreements, including the benefits of the
  transaction being structured as a two-step tender offer and merger, which
  would provide the Company's stockholders with an opportunity to receive
  $7.00 per Share on an accelerated basis;
 
     (2) the presentation of H&Q, the Company's financial advisor, and H&Q's
  opinion to the effect that, as of the date of its opinion and based upon
  and subject to certain matters stated therein, the $7.00 per Share cash
  consideration to be received by the holders of Shares pursuant to the Offer
  and the Merger is fair to the stockholders of the Company from a financial
  point of view (the "Fairness Opinion"). The full text of H&Q's written
  Fairness Opinion is attached hereto as Annex A. Stockholders are urged to,
  and should, read such opinion in its entirety. H&Q presented its final
  Fairness Opinion on March 23, 1999, and the Fairness Opinion concluded that
  the proposed per Share cash consideration is fair to the stockholders from
  a financial point of view;
 
     (3) that the $7.00 per Share tender offer price represents a premium of
  approximately 41.8% over the closing price of the Shares on the Nasdaq
  National Market System ("Nasdaq") on March 19, 1999, and 81.2% over the

  month of trading prior to March 19, 1999;

  history;

     (5) the view of the Company Board of Directors, based in part upon the
  presentation of management and H&Q to the Company Board of Directors,
  regarding the likelihood of a superior offer arising;
 
     (6) the Company's existing competitive and market position, including
  the Company's ability to effectively compete with companies having
  significantly greater financial resources than the Company;
 
     (7) the provisions of the Merger Agreement, including the provision
  allowing the Company to respond to unsolicited bona fide proposals
  concerning an acquisition of the Company that the Company's Board of
  Directors has concluded represents a Superior Proposal, and the provisions
  which permit the Company to terminate the Merger Agreement upon payment to
  Purchaser of a break-up fee and reimbursement of certain expenses under

     (8) the fact that Parent's and Purchaser's obligations under the Merger
  Agreement and the Offer were not subject to any financing condition;
 
     (9) Parent's financial condition and ability to cause Purchaser to meet
  its obligations under the Merger Agreement;

  market or in a future transaction might be less than the $7.00 per Share
  price to be received by holders of Shares in connection with the Offer and
  the Merger;

  terms of the Offer and the Merger Agreement related thereto;
 
     (12) the willingness of the directors, members of management and certain
  large stockholders of the Company to enter into the Stockholder Agreements,
  pursuant to which, among other things, such persons granted to Parent an
  option to purchase the Shares owned by them and Shares resulting from
  exercise of options held by them and that such Stockholders indicated that
  they intended to tender their Shares pursuant to the Offer;
 
     (13) the familiarity of the Company's Board of Directors with the

  Company and the nature of the industry in which it operates; and
 
     (14) the discussions held by the Company and H&Q on the Company's behalf
  with other companies regarding potential business combination transactions
  with the Company.
 
The foregoing discussion of the information and factors considered and given
weight by the Company Board of Directors is not intended to be exhaustive. In
view of the variety of factors considered in connection with its evaluation of
the Merger Agreement and the Offer, the Company Board of Directors did not
find it practicable to, and did not, quantify or otherwise assign relative
weights to the specific factors considered in reaching its determination. In
addition, individual members of the Company Board of Directors may have given
different weights to different factors.

its behalf with respect to the Offer and the Merger.
 
Item 6. Recent Transactions and Intent with Respect to Securities.
 
   (a) No transactions in the Shares have been effected during the past 60
days by the Company or, to the best of the Company's knowledge, by any

   (b) To the best of the Company's knowledge, to the extent permitted by
applicable securities laws, rules or regulations, all of the Company's
executive officers, directors and all entities related to Advent and Cisco who
own Shares presently intend to tender such Shares to Purchaser pursuant to the

Item 7. Certain Negotiations and Transactions by the Subject Company.

in response to the Offer that relate to or would result in one or more of the

Item 8. Additional Information to Be Furnished.
 
   Short Form Merger. Under the DGCL, if Purchaser acquires, pursuant to the
Offer or otherwise, at least 90% of the outstanding shares of Common Stock,
the Purchaser will be able to effect the Merger after consummation of the
Offer without a vote of the Company's stockholders. However, if the Purchaser
does not acquire at least 90% of the outstanding Shares of Common Stock
pursuant to the Offer or otherwise and a vote of the Company's stockholders is
required under Delaware Law, a significantly longer period of time will be
required to effect the Merger.

Attention: Augustus J. Berkeley
Chairman and Chief Executive Officer
 
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 (the "Common
Stock") of Interlink Computer Sciences, Inc. (the "Company") of the
consideration to be received by such stockholders in connection with the
proposed acquisition of the Company by Sterling Software, Inc. ("Acquirer")
pursuant to the Agreement and Plan of Merger to be dated as of March 23, 1999,
among Acquirer, Sterling Software (Southwest), Inc. ("Merger Sub"), a wholly
owned subsidiary of the Acquirer, and the Company (the "Agreement").
 
   We understand that the terms of the Agreement provide, among other things,
that (i) Merger Sub will promptly commence a tender offer (the "Offer") to
purchase for cash, a minimum of 50.1%, and up to 100% of the outstanding
shares of Common Stock at a purchase price of $7.00 per share, net to each of
the selling shareholders, upon the terms and subject to the conditions set
forth in the Agreement; and (ii) Merger Sub will subsequently be merged (the
"Merger") with and into the Company in a transaction that will provide the
holders of Common Stock (other than Acquirer, Merger Sub, and the Company or
their respective subsidiaries) with $7.00 per share in cash. The Offer and the
Merger contemplated by the Agreement constitute the "Proposed Transaction". We
understand that concurrently with the execution of the Agreement, the Acquirer
and certain stockholders (each a "Stockholder") are entering into individual
Stockholder Agreements relating to Acquirer's purchase, under certain
conditions, of the Common Stock of the Company held by each Stockholder as
well as the grant of irrevocable proxies by each Stockholder to the Acquirer,
and an agreement by each Stockholder to vote in favor of the adoption of the
Agreement (the "Stockholder Agreements").
 
   Hambrecht & Quist LLC ("Hambrecht & Quist"), as part of its investment
banking services, is regularly engaged in the valuation of businesses and
their securities in connection with mergers and acquisitions, strategic
transactions, corporate restructurings, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. We have acted as a financial
advisor to the Board of Directors of the Company in connection with the
Proposed Transaction, and we will receive a fee for our services, which
include the rendering of this opinion.

   In connection with our review of the Proposed Transaction, and in arriving
at our opinion, we have, among other things:
 
     (i) reviewed the publicly available consolidated financial statements of
  Acquirer for recent years and interim periods to date and certain other
  relevant financial and operating data of made available to us from
  published sources;
 
     (ii) reviewed the publicly available consolidated financial statements
  of the Company for recent years and interim periods to date and certain
  other relevant financial and operating data of the Company made available
  to us from published sources and from the internal records of the Company;
 
     (iii) reviewed certain internal financial and operating information,
  including certain projections, relating to the Company prepared by the
  management of the Company;
 
     (iv) discussed the business, financial condition and prospects of the
  Company with certain of its officers;
 
     (v) reviewed the recent reported prices and trading activity for the
  Common Stock of the Company and compared such information and certain
  financial information for the Company with similar information for certain
  other companies engaged in businesses we consider comparable;
 
     (vi) reviewed the financial terms, to the extent publicly available, of
  certain comparable merger and acquisition transactions;
 
     (vii) reviewed the Agreement; and
 
     (viii) performed such other analyses and examinations and considered
  such other information, financial studies, analyses and investigations and
  financial, economic and market data as we deemed relevant.
 
   In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning the Company considered in
connection with our review of the Proposed Transaction, and we have not
assumed any responsibility for independent verification of such information.
We have not prepared any independent valuation or appraisal of any of the
assets or liabilities of the Company, nor have we conducted a physical
inspection of the properties and facilities of the Company. With respect to
the financial forecasts and projections made available to us and used in our
analysis, we have assumed that they reflect the best currently available
estimates and judgments of the expected future financial performance of the
Company. Our opinion is necessarily based upon market, economic, financial and
other conditions as they exist and can be evaluated as of the date of this
letter and any change in such conditions would require a reevaluation of this
opinion. We have not been requested to, and do not express any opinion
relating to the terms of the Stockholder Agreements.
 
   It is understood that this letter is for the information of the Board of
Directors in connection with its evaluation of the Proposed Transaction and
may not be used for any other purpose without our prior written consent;
provided, however, that this letter may be reproduced in full in any proxy
statement or solicitation / recommendation statement , as the case may be, in
connection with the Proposed Transaction. This letter does not constitute a
recommendation to any stockholder as to whether such stockholder should accept
the Offer, or vote in favor of the Merger, as the case may be.

matters as we deem relevant, we are of the opinion that as of the date hereof,
the consideration to be received by the holders of Common Stock in the
Proposed Transaction is fair to such holders from a financial point of view.

                INFORMATION STATEMENT PURSUANT TO SECTION 14(f)
                  OF THE SECURITIES EXCHANGE ACT OF 1934 AND
                             RULE 14f-1 THEREUNDER
 
   This Information Statement is being mailed on or about March 30, 1999 as
part of the Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") to holders of shares (the "Rights," and together with the
Common Stock the "Shares") of common stock, $0.001 par value (the "Common
Stock"), of Interlink Computer Sciences, Inc., a Delaware corporation (the
"Company") and the associated preferred share purchase rights issued pursuant
to the Rights Agreement dated February 25, 1998, as amended, between the
Company and BankBoston, N.A. Capitalized terms used herein and not otherwise
defined herein shall have the meanings set forth in the Schedule 14D-9. You
are receiving this Information Statement in connection with the possible
election of persons designated by Sterling Software, Inc. ("Parent") to the
board of directors of the Company (the "Company Board"). Such designation is
to be made pursuant to an Agreement and Plan of Merger, dated March 23, 1999
(the "Merger Agreement"), by and between Parent, Sterling Software
(Southwest), Inc. (the "Purchaser"), an indirect, wholly owned subsidiary of
Parent, and the Company.
 
   This Information Statement is required by Section 14(f) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14f-1
thereunder. You are urged to read this information statement carefully. You
are not, however, required to take any action in connection with this
Information Statement.
 
   Pursuant to the Merger Agreement, the Purchaser has commenced a cash tender
offer to acquire all of the Shares (the "Offer"). The Offer is scheduled to
expire at 12:00 Midnight New York City Time on April 26, 1999, unless the
Offer is extended. Following the successful completion of the Offer, upon
approval by a stockholder vote, if required, and subject to certain other
conditions, the Purchaser will be merged with and into the Company (the
"Merger").
 
   The information contained in this Information Statement concerning Parent
and Purchaser has been furnished to the Company by Parent and Purchaser, and
the Company assumes no responsibility for the accuracy or completeness of such
information.
 
                   GENERAL INFORMATION REGARDING THE COMPANY
 
General
 
   The Common Stock is the only class of voting securities of the Company
outstanding. Each Share entitles its record holder to one vote. As of March
23, 1999, there were 8,308,107 Shares outstanding.
 
The Company's Board of Directors
 
   The Merger Agreement provides that, promptly after (i) the purchase of and
payment for any Shares by Purchaser or any of its affiliates pursuant to the
Offer as a result of which Purchaser and its affiliates own beneficially at
least a majority of then outstanding Shares and (ii) compliance with Section
14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, whichever
shall occur later, Parent will be entitled to designate such number of
directors, rounded up to the next whole number, on the Company Board as is
equal to the product of the total number of directors on such Board (after
giving effect to any increase in the size of such Board) multiplied by the
percentage that the number of Shares beneficially owned by Purchaser at such
time (including Shares accepted for payment) bears to the total number of
Shares then outstanding. The Company has further agreed, upon request of
Parent, to use its best efforts promptly either to increase the size of the
Company Board
<PAGE>
 
or to secure the resignations of such number of its incumbent directors, or
both, as is necessary to enable such designees of Parent to be so elected or
appointed to the Company Board, and to take all actions available to the
Company to cause such designees of Parent to be so elected or appointed. The
Company, if requested by Parent, will also take all action necessary to cause
persons designated by Parent to constitute at least the same percentage
(rounded up to the next whole number) as Parent is entitled to designate on
the Company Board, of each committee of the Company Board, each board of
directors (or similar body) of each subsidiary of the Company, and each
committee (or similar body) of each such board.
 
   Notwithstanding the provisions described above, the Company, Parent and
Purchaser will use their respective reasonable best efforts to ensure that at
least two of the members of the Board shall, at all times prior to the
Effective Time, be directors of the Company who were directors of the Company
on the date hereof (the "Continuing Directors"). If the number of Continuing
Directors shall be reduced below two for any reason, the remaining Continuing
Director may designate a person to fill such vacancy who will be deemed to be
a Continuing Director for all purposes of the Merger Agreement, or if no
Continuing Directors then remain, the other directors of Company then in
office will designate two persons to fill such vacancies who will not be
officers or employees or affiliates of the Company, Parent or either of their
subsidiaries and such persons shall be deemed to be Continuing Directors for
all purposes of the Merger Agreement.
 
   From and after the time, if any, that Parent's designees constitute a
majority of the Company's Board of Directors and prior to the Effective Time,
any amendment or modification of the Merger Agreement, any amendment to the
Company's Certificate of Incorporation or Bylaws inconsistent with the Merger
Agreement, any termination of the Merger Agreement by the Company, any
extension of time for performance of any of the obligations of Parent or
Purchaser under the Merger Agreement, any waiver of any condition to the
Company's obligations under the Merger Agreement or any of the Company's
rights under the Merger Agreement or other action by the Company under the
Merger Agreement may be effected only by the action of a majority of the
Continuing Directors of the Company, which action will be deemed to constitute
the action of any committee specifically designated by the Board of Directors
of Company to approve the actions contemplated under the Merger Agreement and
the full Board of Directors of the Company; provided, that, if there are ever
no Continuing Directors, such actions may be effected by majority vote of the
entire Board of Directors of the Company.

(1) These columns show the hypothetical gains or "option spreads" of the
    options granted based on assumed annual compound stock appreciation rates
    of 5% and 10% over the full seven-year term of the options. The 5% and 10%
    assumed rates of appreciation are mandated by the rules of the SEC and do
    not represent the Company's estimate or projection of future Common Stock
    prices. The gains shown are net of the option exercise price, but do not
    include deductions for taxes or other expenses associated with the
    exercise of the option or the sale of the underlying shares. The actual
    gains, if any, on the exercise of stock options will depend on the future
    performance of the Common Stock, the option holder's continued employment
    through the option period, and the date on which the options are
    exercised.
 
(2) Options vest as to 9/48th of the option shares after nine months from the
    vesting commencement date and as to 1/48th of the option shares each month
    thereafter, with full vesting occurring on the fourth anniversary of the
    vesting commencement date.
 
(3) Options were granted at an exercise price equal to the fair market value
    of the Company's Common Stock. Exercise price may be paid in cash,
    promissory note, by delivery of already-owned shares subject to certain
    conditions, or pursuant to a cashless exercise procedure under which the
    optionee provides irrevocable instructions to a brokerage firm to sell the
    purchased shares and to remit to the Company, out of the sale proceeds, an
    amount equal to the exercise price plus all applicable withholding taxes.
 
(4) Option was granted under the 1996 Director option plan at an exercise
    price equal to the fair market value of the Company's Common Stock on the
    date of grant. Options vest as to 1/48th of the option shares each month,
    with full vesting occurring on the fourth anniversary of the vesting
    commencement date. These options expire ten years from the date of grant.
 
                                       8
<PAGE>
 
(5) Option was granted under an agreement between Mr. Braniff and the Company,
    whereby Mr. Braniff was to act as Interim Chief Executive Officer until a
    full-time Chief Executive Officer was hired. Options vest as to 1/12th of
    the option shares each month, with full vesting occurring on the
    anniversary of the vesting commencement date. Options are also subject to
    certain acceleration clauses.
 
(6) Options vest as to 1/84th of the option shares each month with full
    vesting occurring on the seventh anniversary of the vesting commencement
    date. According to the terms of these grants, if the average share price
    in effect on the grant date doubles and the increased price is sustained
    over a one month period, the options will accelerate their vesting by one
    year. Thereafter, an additional year of vesting will accelerate for every
    $5 of incremental value added to the Company's average stock. The stock
    must retain its increased value over a one month period in order for any
    acceleration of options to occur. The performance based option grant will
    carry a two year minimum vesting schedule regardless of acceleration
    factors.
 
(7) Reflects options that were repriced in February 1998, replacing options
    granted in 1996 or 1997.

                         AGREEMENT AND PLAN OF MERGER
     
     This AGREEMENT AND PLAN OF MERGER, dated as of March 23, 1999 (this
"Agreement"), is made and entered into among Sterling Software, Inc., a Delaware
corporation ("Parent"), Sterling Software (Southwest), Inc., a Delaware
corporation and indirect wholly owned subsidiary of Parent ("Purchaser"), and
Interlink Computer Sciences, Inc., a Delaware corporation ("Company").

                                   RECITALS:
     
     A.   The Executive Committee of the Board of Directors of Parent and the
respective Boards of Directors of Purchaser and Company have determined that it
would be advisable and in the best interests of their respective stockholders
for Parent to acquire Company by means of a merger of the Purchaser with and
into Company (the "Merger"), on the terms and subject to the conditions set
forth in this Agreement.
     
     B.   To effectuate the acquisition, Parent and Company each desire that
Parent cause Purchaser to commence a cash tender offer to purchase all of the
outstanding shares of common stock, par value $.001 per share, of Company (the
"Shares") (including the associated Preferred Stock Purchase Rights (the
"Rights") issued pursuant to the Preferred Shares Rights Agreement between
Company and BANKBOSTON, N.A., dated as of February 25, 1998 (the "Company Rights
Agreement")) on the terms and subject to the conditions set forth in this
Agreement and the Offer Documents (as defined in Section 1.2) and the Board of
Directors of Company has unanimously approved such tender offer and is
recommending (subject to the limitations contained herein) that Company's
stockholders accept the tender offer and tender their Shares pursuant thereto.

     C.   Concurrently with the execution and delivery of this Agreement and as
a condition to Parent's and Purchaser's willingness to enter into this
Agreement, Parent and Purchaser have entered into separate Stockholder
Agreements, dated as of the date hereof (the "Stockholder Agreements"), with
each of the Principal Stockholders (as defined in Section 9.3), pursuant to
which each Principal Stockholder has (x) agreed, among other things, to vote all
Shares owned by such Principal Stockholder in favor of the Merger and (y)
granted to Parent an option to purchase all Shares owned by such Principal
Stockholder.
<PAGE>
 
     D.   Parent, Purchaser and Company desire to make certain representations
and warranties and to enter into certain covenants in connection with the Offer
(as defined in Section 1.1) and the Merger and also to prescribe various
conditions to the consummation thereof.

     NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties and covenants contained in this Agreement, the parties hereto,
intending to be legally bound hereby, agree as follows:
    
                                   ARTICLE I
     
                                   THE OFFER
     
     Section 1.1    The Offer. (a) Provided that none of the events set forth in
                    ---------
Exhibit A hereto shall have occurred and be continuing, as promptly as
practicable (but in any event not later than five business days after the public
announcement of the execution and delivery of this Agreement), Parent shall
cause Purchaser to commence (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")), an offer to
purchase (the "Offer") all outstanding Shares at a price of $7.00 per share, net
to the seller in cash (as paid pursuant to the Offer, the "Offer
Consideration"). The obligation of Parent and Purchaser to commence the Offer,
to consummate the Offer and to accept for payment and to pay for Shares validly
tendered in the Offer and not withdrawn shall be subject only to those
conditions set forth in Exhibit A hereto.

          (b)   Without the prior written consent of Company, Purchaser shall
not (and Parent shall cause Purchaser not to) (i) decrease or change the form of
the Offer Consideration or decrease the number of Shares sought pursuant to the
Offer, (ii) impose additional conditions to the Offer, (iii) extend the
expiration date of the Offer beyond the initial expiration date of the Offer
(which shall be the 20th business day after commencement of the Offer), except
(A) as required by applicable law, (B) that if, immediately prior to the
expiration date of the Offer (as it may be extended), the Shares tendered and
not withdrawn pursuant to the Offer constitute more than 75% and less than 90%
of the outstanding Shares, Purchaser may extend the Offer for one or more
periods not to exceed an aggregate of ten business days, notwithstanding that
all conditions to the Offer are satisfied as of such expiration date of the
Offer and (C) that if any condition to the Offer has not been satisfied or
waived, Purchaser may, in its sole discretion, extend the expiration date of the
Offer

                                       2
<PAGE>
 
for one or more periods provided, that the expiration date of the Offer may not
be extended beyond July 31, 1999, (iv) waive the condition (the "Minimum
Condition") that there shall be validly tendered and not withdrawn prior to the
time the Offer expires a number of Shares which, when added to the number of
Shares which Parent, Purchaser or any other Subsidiary of Parent "beneficially
owns" (within the meaning of Rule 13d-3 under the Exchange Act), constitutes at
least a majority of the Shares outstanding on a fully-diluted basis on the date
of purchase ("on a fully-diluted basis" meaning, as of any date, the number of
Shares outstanding, together with the Shares which Company may be required to
issue pursuant to warrants, options or obligations outstanding at that date
under employee stock or similar benefit plans or otherwise whether or not vested
or then exercisable), or (v) amend any term or other condition of the Offer in
any manner materially adverse to holders of Shares; provided, however, that,
except as set forth above and subject to applicable legal requirements,
Purchaser may waive any condition to the Offer other than the Minimum Condition
in its sole discretion; and provided further that the Offer may be extended in
connection with an increase in the consideration to be paid pursuant to the
Offer so as to comply with applicable rules and regulations of the United States
Securities and Exchange Commission (the "SEC"). Purchaser shall, on the terms
and subject to the prior satisfaction or waiver of the conditions of the Offer,
accept for payment, and pay for, in accordance with the terms and subject to the
conditions of the Offer, all Shares validly tendered and not withdrawn pursuant
to the Offer as soon as practicable after the expiration date thereof.
Notwithstanding the foregoing, if all the conditions to the Offer have not been
satisfied or waived at the initial expiration date of the Offer and all such
conditions are reasonably capable of being satisfied within the applicable
period set forth below, the Purchaser shall (i) extend the Offer for 10 business
days from the initial expiration date of the Offer or (ii) extend the Offer for
20 business days from the initial expiration date of the Offer if the condition
contained in Section 7.1(d) hereof has not been satisfied and is reasonably
capable of being satisfied.
     
     Section 1.2  Offer Documents. (a) On the date of commencement of the Offer,
                  ---------------
Parent and Purchaser shall file or cause to be filed with the SEC a Tender Offer
Statement on Schedule 14D-1 (the "Schedule 14D-1") with respect to the Offer
which shall contain the offer to purchase and related letter of transmittal and
other ancillary Offer documents and instruments pursuant to which the Offer will
be made (collectively, and with any supplements or amendments thereto, the
"Offer Documents"). Company will promptly supply to Parent and Purchaser in
writing, for inclusion in the Offer Documents, all information concerning
Company required 

                                       3
<PAGE>
 
under the Exchange Act and the rules and regulations thereunder to be included
in the Offer Documents.

          (b)   The Offer Documents will comply in all material respects with
the provisions of applicable federal securities laws and, on the date filed with
the SEC and on the date first published, sent or given to Company's
shareholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation is made by Parent or
the Purchaser with respect to information supplied by Company in writing for
inclusion in the Offer Documents. Each of Parent and the Purchaser further
agrees to take all steps necessary to cause the Offer Documents to be filed with
the SEC and to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws. Each of Parent, Purchaser
and Company shall promptly correct any information provided by them for use in
the Offer Documents if and to the extent that such information shall be or have
become false or misleading in any material respect, and Parent and Purchaser
shall take all lawful action necessary to cause the Offer Documents as so
corrected to be filed promptly with the SEC and to be disseminated to holders of
Shares as and to the extent required by applicable law. Company and its counsel
shall be given a reasonable opportunity to review and comment on the Offer 
Documents and any amendments thereto prior to the filing thereof with the SEC.
Parent and Purchaser agree to provide the Company and its counsel any comments
Parent, Purchaser or their counsel may receive from the SEC or its staff with
respect to the Offer Documents promptly after the receipt of such comments.

          (c)   Parent shall provide or cause to be provided to Purchaser on a
timely basis the funds necessary to accept for payment and pay for any Shares
that the Purchaser becomes obligated to accept for payment and pay for pursuant

SEC and on the date first published, sent or given to Company's shareholders,
shall not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that no representation is made by Company with respect to

Schedule 14D-9. Company further agrees to take all steps necessary to cause the
Schedule 14D-9 to be filed with the SEC and to be disseminated to holders of
Shares, in each case as and to the extent required by applicable federal
securities laws. Each of Company, Parent and Purchaser shall promptly correct
any information provided by them for use in the Schedule 14D-9 if and to the
extent that such information shall be or have become false or misleading in any
material respect and Company shall take all lawful action necessary to cause the

Parent and its counsel any comments Company or its counsel receive 

                                       5
<PAGE>
 
from the SEC or its staff with respect to the Schedule 14D-9 promptly after
receipt of such comments.

              (c)   In connection with the Offer, Company shall promptly furnish
Parent and Purchaser with mailing labels, security position listings and all
available listings or computer files containing the names and addresses of the
record holders of Shares as of the latest practicable date and shall furnish
Parent and Purchaser with such information and assistance (including updated
lists of stockholders, mailing labels and lists of security positions) as Parent
and Purchaser or their agents may reasonably request in communicating the Offer
to the record and beneficial holders of Shares. Subject to the requirements of
applicable law, and except for such actions as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Offer and
the Merger, Parent and Purchaser shall, and shall use commercially reasonable
efforts to cause each of their affiliates, associates, partners, employees,
agents and advisors to, hold in confidence the information contained in such
labels, lists and files, and all other information delivered pursuant to this
Section 1.3(c), shall use such information only in connection with the Offer and
the Merger and, if this Agreement is terminated in accordance with its terms,
shall deliver promptly to Company all copies of such information (and any
copies, compilations or extracts thereof or based thereon) then in their
possession or under their control.

     Section 1.4  Directors. (a) Promptly after (i) the purchase of and payment
                  ---------
for any Shares by Purchaser or any of its affiliates pursuant to the Offer as a
result of which Purchaser and its affiliates own beneficially at least a
majority of then outstanding Shares and (ii) compliance with Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder, whichever shall occur
later, Parent shall be entitled to designate such number of directors, rounded
up to the next whole number, on Company's Board of Directors as is equal to the
product of the total number of directors on such Board (after giving effect to
any increase in the size of such Board pursuant to this Section 1.4) multiplied
by the percentage that the number of Shares beneficially owned by Purchaser at
such time (including Shares so accepted for payment) bears to the total number
of Shares then outstanding. In furtherance thereof, Company shall, upon request
of Parent, use its best efforts promptly either to increase the size of its
Board of Directors or to secure the resignations of such number of its incumbent
directors, or both, as is necessary to enable such designees of Parent to be so
elected or appointed to Company's Board of Directors, and Company shall take all
actions available to Company to cause such designees of Parent to be so elected
or appointed. At such time, Company shall, if requested by 

                                       6
<PAGE>
 
Parent, also take all action necessary to cause persons designated by Parent to
constitute at least the same percentage (rounded up to the next whole number) as
is on Company's Board of Directors of (i) each committee of Company's Board of
Directors, (ii) each board of directors (or similar body) of each Subsidiary (as
defined in Section 9.3) of Company and (iii) each committee (or similar body) of
each such board.
     
          (b)   Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under Section 1.4(a), including mailing to
stockholders the information required by such Section 14(f) and Rule 14f-1 (or
including such information in the Schedule 14D-9 initially filed with the SEC
and distributed to the stockholders of Company) as is necessary to enable
Parent's designees to be elected to Company's Board of Directors. Parent or
Purchaser will supply to Company in writing and be solely responsible for any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-1. The
provisions of this Section 1.4 are in addition to and shall not limit any rights
which Purchaser, Parent or any of their affiliates may have as a holder or
beneficial owner of Shares as a matter of applicable law with respect to the
election of directors or otherwise.

          (c)   Notwithstanding the provisions of this Section 1.4, the parties
hereto shall use their respective reasonable best efforts to ensure that at
least two of the members of the Board shall, at all times prior to the Effective
Time (as defined in Section 1.6 hereof) be, directors of the Company who were
directors of the Company on the date hereof (the "Continuing Directors"),
provided that, if the number of Continuing Directors shall be reduced below two
for any reason, the remaining Continuing Director may designate a person to fill
such vacancy who shall be deemed to be a Continuing Director for all purposes of
this Agreement, or if no Continuing Directors then remain, the other directors
of Company then in office shall designate two persons to fill such vacancies who
will not be officers or employees or affiliates of Company, Parent or either of
their subsidiaries and such persons shall be deemed to be Continuing Directors
for all purposes of this Agreement. From and after the time, if any, that
Parent's designees constitute a majority of Company's Board of Directors and
prior to the Effective Time, any amendment or modification of this Agreement,
any amendment to Company's Certificate of Incorporation or By-Laws inconsistent
with this Agreement, any termination of this Agreement by Company, any extension
of time for performance of any of the obligations of Parent or Purchaser
hereunder, any waiver of any condition to Company's obligations

<PAGE>
 
hereunder or any of Company's rights hereunder or other action by Company
hereunder may be effected only by the action of a majority of the Continuing
Directors of Company, which action shall be deemed to constitute the action of
any committee specifically designated by the Board of Directors of Company to
approve the actions contemplated hereby and the full Board of Directors of
Company; provided, that, if there shall be no Continuing Directors, such actions
         --------  ----
may be effected by majority vote of the entire Board of Directors of Company.

Parent, Purchaser or any other Subsidiary of Parent (other than shares in trust
accounts, managed accounts, custodial accounts and the like that are

Certificate (as defined in Section 3.3).

the contrary, Shares issued and outstanding immediately prior to the Effective
Time held by any person who has the right to demand, and who properly demands,
an appraisal of such Shares ("Dissenting Shares") in accordance with Section 262
of the DGCL (or any successor provision) shall not be converted into a right to
receive the Merger Consideration unless such holder fails to perfect or
otherwise loses such holder's right to such appraisal, if any. If, after the
Effective Time, such holder fails to perfect or loses any such right to
appraisal, each such Share of such holder shall be treated as a Share that had

Consideration in accordance with Section 3.1(c). At the Effective Time, any
holder of Dissenting Shares shall cease to have any rights with respect thereto,
except the rights provided in Section 262 of the DGCL (or any successor

Stock (collectively, the "Options") under Company's 1992 Stock Option Plan and
1996 Director Stock Option Plan (collectively, the "Stock Option Plans") or

                  (a)  Payment Fund. Concurrently with the Effective Time,
                       ------------
Parent shall deposit, or shall cause to be deposited, with or for the account of
a bank or trust company having net capital of not less than $100,000,000
designated by Parent, which shall be reasonably satisfactory to Company (the
"Paying Agent"), for the benefit of the holders of Shares, cash in an amount
sufficient to pay the aggregate Merger Consideration payable upon the conversion
of Shares pursuant to Section 3.1(c) (the "Payment Fund").
     
                  (b)  Letters of Transmittal; Surrender of Certificates. 
                       -------------------------------------------------
As soon as reasonably practicable after the Effective Time, Parent shall
instruct the Paying Agent to mail to each holder of record (other than Company
or any of its Subsidiaries or Parent, Purchaser or any other Subsidiary of
Parent) of a certificate or certificates that, immediately prior to the
Effective Time, evidenced outstanding Shares (the "Certificates"), (i) a form of
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon proper delivery
of the Certificates to the Exchange Agent, and shall be in such form

                                      11
<PAGE>
 
and have such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration. Upon surrender of a Certificate for cancellation

such other customary documents as may be required pursuant to such instructions,
the holder of such Certificate shall be entitled to receive in exchange therefor
cash in an amount equal to the product of (i) the number of Shares theretofore
represented by such Certificate and (ii) the Merger Consideration, and the
Certificate so surrendered shall forthwith be canceled. No interest shall be
paid or accrued on any cash payable upon the surrender of any Certificate. If
payment is to be made to a person other than the person in whose name the
surrendered Certificate is registered, it shall be a condition of payment that
the Certificate so surrendered shall be properly endorsed or otherwise in
proper form for transfer and that the person requesting such payment shall pay
any transfer or other taxes required by reason of the payment to a person other
than the registered holder of the surrendered Certificate or established to the
satisfaction of Parent and the Surviving Corporation that such taxes have been
paid or are not applicable.
     
          (c)  Cancellation and Retirement of Shares; No Further Rights. As of
               --------------------------------------------------------
the Effective Time, all Shares (other than Shares to be canceled in accordance
with Section 3.1(b)) issued and outstanding immediately prior to the Effective
Time shall cease to be outstanding and shall automatically be canceled and
retired and shall cease to exist, and each holder of any such Shares shall cease
to have any rights with respect thereto or arising therefrom (including without
limitation the right to vote), except the right to receive the Merger
Consideration, without interest, upon surrender of such Certificate in
accordance with Section 3.3(b), and until so surrendered, each such Certificate
shall represent for all purposes only the right to receive the Merger
Consideration, without interest. The Merger Consideration paid upon the
surrender for exchange of Certificates in accordance with the terms of this
Section 3.3 shall be deemed to have been paid in full satisfaction of all rights
pertaining to the Shares theretofore represented by such Certificates.
     
          (d)  Investment of Payment Fund. The Paying Agent shall invest the
               ---------------------------

States of America, (ii) obligations for which the full faith and credit of the
United States of America is pledged to provide for the payment of principal and
interest, (iii) commercial paper rated the highest quality by either Moody's
Investors Services, Inc. or Standard & Poor's Corporation, or (iv) certificates
of deposit, bank repurchase agreements or bankers' acceptances of commercial
banks with capital exceeding 

                                      12
<PAGE>
 
$500 million. Any net earnings with respect to the Payment Fund shall be the
property of and paid over to Parent as and when requested by Parent.

          (e)  Termination of Payment Fund. Any portion of the Payment Fund
               ---------------------------
which remains undistributed to the holders of Certificates for 180 days after
the Effective Time shall be delivered to Parent, upon demand, and any holders of
Certificates that have not theretofore complied with this Section 3.3 shall
thereafter look only to Parent, and only as general creditors thereof, for
payment of their claim for any Merger Consideration.
     
          (f)  No Liability. None of Parent, Purchaser, the Surviving
               ------------
Corporation or the Paying Agent shall be liable to any person in respect of any
payments or distributions payable from the Payment Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
If any Certificates shall not have been surrendered prior to five years after
the Effective Time (or immediately prior to such earlier date on which any
Merger Consideration in respect of such Certificate would otherwise escheat to
or become the property of any Governmental Entity (as defined in Section
4.1(c)), any amounts payable in respect of such Certificate shall, to the extent
permitted by applicable law, become the property of the Surviving Corporation,
free and clear of all claims or interest of any person previously entitled
thereto.

          (g)  Withholding Rights. Parent shall be entitled to deduct and
               ------------------
withhold, or cause to be deducted or withheld, from the consideration otherwise
payable pursuant to this Agreement to any holder of Shares, Options or
Certificates such amounts as are required to be deducted and withheld with
respect to the making of such payment under the Code, or any provision of
applicable state, local or foreign tax law. To the extent that amounts are so
deducted and withheld, such deducted and withheld amounts shall be treated for
all purposes of this Agreement as having been paid to such holders in respect of
which such deduction and withholding was made.

products and the services presently offered by Company. Except as specified in
Section 4.1(i)(ii) of the Disclosure Schedule, no person other than Company and

               (iii)  Section 4.1(i)(iii) of the Disclosure Schedule sets forth
a true, correct and complete list, by computer program, of (A) all persons other
than Company and its Subsidiaries that have been provided with the source code

either with or without the giving of notice or passage of time or both) for any
of the Owned Software, and (B) all source code escrow agreements relating to any
of the Owned Software (setting forth as to any such escrow agreement the source
code subject thereto and the names of the escrow agent and all other persons who
are actual or potential beneficiaries of such escrow agreement), and lists all
agreements and arrangements pursuant to which the execution, delivery and
performance of this Agreement or the consummation of the transactions
contemplated hereby would entitle any third party or parties to receive
possession of the source code for any of the Owned Software or any related
technical documentation. Except as specified in Section 4.1(i)(iii) of the

Software.
     
               (iv)   There are no defects in any computer program included in

fail to be Year 2000 compliant. Without limiting the generality of the
foregoing, all of the Software has the following properties and capabilities:
(A) the capability to correctly recognize and accurately process dates expressed
as a four-digit number (or the binary equivalent or other machine readable
iteration thereof) (collectively, the "Four-Digit Dates"); (B) the capability to

<PAGE>
 
continue processing with Four-Digit Dates; and (F) the capability to provide
correct results in forward and backward data calculations spanning century
boundaries, including the conversion of pre-2000 dates currently stored as two-
digit dates; provided, however, that no representation or warranty is made as to
the effect that defects in computer programs, hardware or systems provided by
third parties (or the inability of any such programs, hardware or systems, other
than those contemplated by the documentation for the Software to be used in
conjunction with the Software, to properly exchange date data with the Software)
may, when used in conjunction with the Software, have on the foregoing
capabilities. Each computer program included in the Software is in machine
readable form and contains all current revisions. Section 4.1(i)(iv) of the

otherwise furnished Software or related products or services.
     
               (v)    Except as specified in Section 4.1(i)(v) of the Disclosure
Schedule, none of the sale, license, lease, transfer, use, reproduction,
distribution, modification or other exploitation by Company, any Subsidiary of
Company or any of their respective successors or assigns of any version or
release of any computer program included in the Software obligates or will
obligate Company, any Subsidiary of Company or any of their respective
successors or assigns to pay any royalty, fee or other compensation to any other
person.
     
               (vi)   Neither Company nor any of its Subsidiaries markets, or
has marketed, and none of them has supported or is obligated to support, any
Licensed Software.

Disclosure Schedule, no agreement, license or other arrangement pertaining to
any of the Software (including without limitation any development, distribution,
marketing, user or maintenance agreement, license or arrangement) to which
Company or any Subsidiary of Company is a party will terminate or become
terminable by any party thereto as a result of the execution, delivery or
performance of this Agreement or the consummation of the transactions
contemplated hereby.

intellectual property rights owned or licensed by Company and its Subsidiaries
that are reasonably necessary to conduct Company's business as it is now
conducted or is expected to be conducted, and includes all of the intellectual
property rights owned by or licensed to Company and its Subsidiaries that are
used in the development, marketing, licensing or support of the Software.

Company, directly or through its Subsidiaries, has good, marketable and
exclusive title to, and the valid and enforceable power and unqualified right to

advisory and/or opinion letter, as applicable, from the IRS that it is so
qualified or still has remaining a period of time under applicable Treasury
Regulations or Internal Revenue Service pronouncements in which to apply for
such a letter and to make any 

                                      29
<PAGE>
 
amendments necessary to obtain a favorable determination and nothing has

expected to give rise to any such liability;

Company ERISA Plan subject to Title IV of ERISA (as of the date of the most
recent actuarial valuation prepared for such Company ERISA Plan and based on the
discount rate and other actuarial assumptions used in such valuation) do not
exceed the fair market value of the assets of such Company ERISA Plan (as of the
date of such valuation);

                    (ix)   Company is not aware of any claims relating to the
Company Plans, other than routine claims for benefits;

                    (x)    None of the Company Plans provides for benefits or

participation in or benefits under any Company Plan, by any individual
classified or treated by Company as an independent contractor; and

1992 Stock Option Plan) that has been granted by the Company or any of its
Subsidiaries is outstanding; 

                    provided, however, that the failure of the representations
set forth in clauses (v), (vi), (vii), (ix) and (x) to be true and correct shall
not be deemed to be a breach of any such representation unless such failures
could reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect on Company.

be paid by Company, is entitled to any broker's, finder's, financial advisor's
or other similar fee or commission in connection with the transactions
contemplated hereby based upon arrangements made by or on behalf of Company.
     
               (u)  Written Opinion of Financial Advisor. Company has received
                    ------------------------------------
the written opinion of Hambrecht & Quist, dated March 23, 1999 (a true, correct
and complete copy of which has been delivered to Parent by Company), to the
effect that, based upon and subject to the matters set forth therein and as of
the date thereof, the Offer Consideration and the Merger Consideration to be
received by the holders of Shares in the Offer and the Merger, respectively, is
fair, from a financial point of view, to such holders and such opinion has not

DGCL is inapplicable and unavailable to effectuate the Merger, the affirmative

the Stockholders Meeting (as defined in Section 6.1(a)) with respect to the
adoption of this Agreement is the only vote of the holders of any class or
series of Company's capital stock or other securities required in connection

contemplated hereby to be consummated by Company. The restrictions contained in
Section 203 of the DGCL are not applicable to this Agreement, the Stockholder

the Offer and the execution and delivery of this Agreement (and any amendments
thereto by the parties hereto) and the Stockholder Agreements, and the
consummation of the Merger and the transactions contemplated hereby and by the
Stockholder Agreements, will not cause (i) Parent or Purchaser to constitute an
"Acquiring Person" (as defined in the Company Rights Agreement), (ii) a
"Distribution Date," "Section 13 Event," "Triggering Event," or "Shares
Acquisition Date" (each as defined in the Company Rights Agreement) to occur or
(iii) the Rights (as defined in the Company Rights Agreement) to become
exercisable pursuant to Section 11(a)(ii) thereof or otherwise. The Rights
Amendment is sufficient to render 

                                      32
<PAGE>
 
the Rights inoperative with respect to the acquisition of Shares by Parent,
Purchaser or their affiliates pursuant this Agreement, the Offer and/or the
Stockholder Agreements. As a result of the Rights Amendment, the Rights shall
not be exercisable upon or at any time after the acceptance for payment of
Shares pursuant to the Offer and/or the purchase of, or right to acquire, Shares
pursuant to the Stockholder Agreements. A true and correct copy of the Rights
Amendment has been delivered to Parent.

Agreement"), is a valid and binding obligation of the parties thereto,
enforceable in accordance with its terms. Neither the Company nor Selesta has
breached any provision of, or is in default in any respect under, and no
condition exists which, with the passage of time, the giving of notice of, or
both would result in a default by the Company or Selesta under, the terms of the
Selesta Settlement Agreement. The Company has provided to Parent a true, correct
and complete copy of the Selesta Settlement Agreement.

     regulations thereunder. Parent, Purchaser and Company will cooperate with
     each other in the preparation of the Proxy Statement. Without limiting the
     generality or effect of the foregoing, Company shall use its commercially
     reasonable efforts to respond to all SEC comments with respect to the Proxy
     Statement and, subject to compliance with SEC rules and regulations, to
     cause the Proxy Statement to be mailed to Company's stockholders at the
     earliest practicable date. Each of Parent and Purchaser shall promptly
     supply to Company in writing, for inclusion in the Proxy Statement, all

     acquire at least 90% of the outstanding Shares in the Offer, the parties
     hereto shall, at the request of Purchaser, take all necessary actions to
     cause the Merger to become effective, as soon as practicable after the
     expiration of the Offer, without a meeting of stockholders of Company,
     in accordance with Section 253 of the DGCL.

     initiate, or intentionally encourage, directly or indirectly, any inquiries
     relating to, or the submission of, any Acquisition Proposal, (ii)
     participate in any discussions or negotiations regarding any Acquisition
     Proposal, or, in connection with any Acquisition Proposal, furnish to
     any Person any information or data with respect to or access to the
     properties of Company or any of its Subsidiaries, or take any other action,
     to knowingly facilitate the making of any proposal that constitutes, or may
     reasonably be expected to lead to, any Acquisition Proposal or (iii) enter
     into any agreement with respect to any Acquisition Proposal or approve or
     resolve to approve any Acquisition Proposal; provided, that nothing
     contained in this Section 6.5 or any other provision hereof shall prohibit
     Company or Company's Board of Directors from (i) taking and disclosing to
     Company's stockholders a position with respect to a tender or exchange
     offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated under
     the Exchange Act, or (ii) making such disclosure to Company's stockholders
     as, in the good faith judgment of Company's Board of Directors, after

     modify, its position with respect to the Offer or the Merger or approve or
     recommend, or propose to approve or recommend any Acquisition Proposal, or
     enter into any agreement with respect to any Acquisition Proposal. Upon

     foregoing, prior to the time of acceptance of Shares for payment pursuant

     Subsidiaries' business, properties or assets to any person or group and may
     negotiate and participate in discussions and negotiations with such person
     or group concerning an Acquisition Proposal, provided that such person or
     group shall have entered into a confidentiality agreement, the
     confidentiality provisions of which shall be no more favorable to such
     third party than those provided for in the Letter Agreement, if:
     
                         (x)  such Person or group has submitted a Superior 
          Proposal; and     

                         (y)  in the opinion of Company's Board of Directors
          such action is required to discharge the Board's fiduciary duties to

          stockholders under applicable law, determined only after consultation
          with independent legal counsel to Company.

     Company will promptly (but in no case later than 24 hours) notify Parent in
     writing of the existence of any proposal, discussion, negotiation or
     inquiry received by Company regarding any Acquisition Proposal, and Company
     will promptly communicate to Parent the terms of any proposal, discussion,
     negotiation or inquiry which it may receive regarding any Acquisition
     Proposal (and will promptly provide to Parent copies of any written
     materials received by Company in connection with such proposal, discussion,
     negotiation or inquiry) and the identity of the party making such proposal
     or inquiry or engaging in such discussion or negotiation. Company will
     promptly provide to Parent any non-public information concerning Company
     provided to any other person in connection with any Acquisition Proposal
     which was not previously provided to Parent. Company will keep Parent
     informed of the status and details of any such Acquisition Proposal and of
     any amendments or proposed amendments to any Acquisition Proposal and of
     the status of any discussions or negotiations relating to any Acquisition
     Proposal and will promptly (but in no case later than 24 hours) notify
     Parent of any determination by Company's Board of Directors that a Superior
     Proposal has been made.
     
               (b)  Except as set forth in this Section 6.5, neither the Board
     of Directors of Company nor any committee thereof shall (i) withdraw or
     modify, or propose to withdraw or modify, in a manner adverse to Parent or
     Purchaser, the approval or recommendation by the Board of Directors of
     Company of the Offer, this Agreement or the Merger, (ii) approve or
     recommend, or propose to approve or recommend, any Acquisition Proposal or
     (iii) enter into any agreement with respect to any Acquisition Proposal.
     Notwithstanding the foregoing or anything else herein, subject to
     compliance with the provisions of this Section 6.5, prior to the time of
     acceptance for payment of Shares pursuant to the Offer, Company's Board of
     Directors may withdraw or modify its approval or recommendation of the
     Offer, this Agreement or the Merger, approve or recommend a Superior
     Proposal, or enter into an agreement with respect to a Superior Proposal,
     in each case at any time after the third business day following Parent's
     receipt of written notice (including by facsimile) from Company advising
     Parent that the Board of Directors of Company has received a Superior
     Proposal which it intends to accept, specifying the material terms and
     conditions of such Superior Proposal and identifying the person making such
     Superior Proposal, but only if Company shall have caused its financial and
     legal advisors to negotiate with Parent to make such adjustments to the
     terms and conditions of this Agreement as would enable Company to 
     proceed with the transactions

                                      43

contemplated hereby on such adjusted terms.  
     
          (c)     Nothing in this Section 6.5, and no action taken by the Board
of Directors of Company pursuant to this Section 6.5, will (i) permit Company to
enter into any agreement providing for any transaction contemplated by an
Acquisition Proposal for as long as this Agreement remains in effect or (ii)
affect in any manner any other obligation of Company under this Agreement.

          (d)     For purposes of this Agreement, "Acquisition Proposal" means
any bona fide offer, proposal or other indication of interest regarding any of
the following (other than the transactions provided for in this Agreement
involving Company): (i) any merger, consolidation, share exchange,
recapitalization, business combination or other similar transaction involving
the Company or any of its Subsidiaries; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of a significant portion of the
assets of Company and its Subsidiaries, taken as a whole, in a single
transaction or series of related transactions (other than sales of inventory or
used equipment in the ordinary course of business); (iii) any purchase of, or
tender offer or exchange offer for, 20% percent or more of the outstanding
shares of capital stock of Company by any person or the filing of a registration
statement under the Securities Act in connection therewith; or (iv) any public
announcement of a proposal, plan or intention to do any of the foregoing or any
agreement to engage in any of the foregoing. For purposes of this Agreement,
"Superior Proposal" means an unsolicited Acquisition Proposal on terms which the
Board of Directors of Company determines in good faith to be more favorable to
Company's stockholders than the Offer and the Merger (based on advice of 
Company's independent financial advisor that the value of the consideration
provided for in such proposal is superior to the value of the consideration
provided for in the Offer and the Merger); for which financing, to the extent
required, is then committed or which, in the good faith reasonable judgment of
the Board of Directors of Company (based on advice from Company's independent
financial advisor) is reasonably capable of being financed by such third party
provided that the Board of Directors of the Company has also, among other
things, duly considered the timing of such Acquisition Proposal and the
likelihood that such Acquisition Proposal will be consummated.

limit its operation of or take similar action with respect to any assets
(tangible or intangible) or any business interest of it or any of its
Subsidiaries (including without limitation the Surviving Corporation after
consummation of the Offer or the Merger) in connection with or as a condition to
receiving the consent or approval of any Governmental Entity (including without
limitation under the HSR Act). In case at any time after the Effective Time any
further action is necessary or desirable to carry out the purposes of this
Agreement, the proper officers and directors of each party to this Agreement
shall use their commercially reasonable efforts to take all such action.

     Section 6.7    Employee Benefit Matters.
                    ------------------------
     
          (a)       From and after the Effective Time, Parent shall, and shall
cause its Subsidiaries (including the Surviving Corporation) to, honor and
provide for payment of all accrued obligations and benefits under all Company
Plans and employment or severance agreements disclosed on the Disclosure
Schedule between Company and persons who are or had been employees of Company or
any of its Subsidiaries at or prior to the Effective Time ("Covered Employees"),
all in accordance with their respective terms.
     
          (b)       From and after the Effective Time, Parent shall, and shall
cause its Subsidiaries (including the Surviving Corporation) to, provide Covered
Employees who remain in the employ of Company or any of its Subsidiaries with
employee benefits that are reasonably comparable to the employee benefits
provided to similarly situated employees of Parent or any such Subsidiary who
are not Covered Employees. To the extent that Covered Employees are included in
any benefit plan of Parent or its Subsidiaries, Parent agrees that the Covered
Employees shall receive credit under such plan (other than any such plan
providing for sabbati-

                                      45
<PAGE>
 
cals) for service prior to the Effective Time with Company and its Subsidiaries
to the same extent such service was counted under similar Company Plans for
purposes of eligibility, vesting, eligibility for retirement (but not for
benefit accrual) and, with respect to vacation, disability and severance,
benefit accrual. To the extent that Covered Employees are included in any
medical, dental or health plan other than the plan or plans they participated in
at the Effective Time, Parent agrees that any such plans shall not include pre-
existing condition exclusions, except to the extent such exclusions were
applicable under the similar Company Plan at the Effective Time, and shall
provide credit for any deductibles and co-payments applied or made with respect
to each Covered Employee in the calendar year of the change.

          (c)     Notwithstanding anything in this Agreement to the contrary,
from and after the Effective Time, the Surviving Corporation will have sole
discretion over the hiring, promotion, retention, firing and other terms and
conditions of the employment of employees of the Surviving Corporation. Except
as otherwise provided in this Section 6.7, nothing herein shall prevent Parent
or the Surviving Corporation from amending or terminating any Company Plan in
accordance with its terms.
     
          (d)     "Offering Periods" under the Company 1996 Employee Stock
Purchase Plan (the "ESPP") shall terminate on the earlier to occur of (i) April
30, 1999, or (ii) the expiration date of the Offer, and the Company shall cause
written notice to be given to participants in accordance with the terms of the
ESPP. No further Offering Period under the ESPP shall be created.
     
     Section 6.8  Indemnification; Directors' and Officers' Insurance.
                  ---------------------------------------------------

          (a)     For a period of four years after the Effective Time, the
provisions with respect to indemnification set forth in the certificate of
incorporation and bylaws of Purchaser as in effect on the date of this Agreement
(true, correct and complete copies of which have been provided to Company) shall
not be amended, repealed or otherwise modified in any manner that would
adversely affect the rights thereunder of individuals who at any time prior to
the Effective Time were directors or officers of Company in respect of actions
or omissions occurring at or prior to the Effective Time (including without
limitation the transactions contemplated by this Agreement), unless such
modification is required by law.
     
          (b)     From and after the Effective Time, Parent shall, or shall
cause the Surviving Corporation to, indemnify, defend and hold harmless each
person who 

                                      46
<PAGE>
 
is now, or has been at any time prior to the date hereof or who becomes prior to
the Effective Time, an officer or director of Company (the "Indemnified
Parties") against all losses, claims, damages, costs, expenses (including
reasonable attorneys' fees and expenses), liabilities or judgments or amounts
that are paid in settlement with the approval of the indemnifying party (which
approval shall not be unreasonably withheld) incurred in connection with any
threatened or actual action, suit or proceeding based in whole or in part on or
arising in whole or in part out of the fact that such person is or was a
director or officer of Company ("Indemnified Liabilities"), including all
Indemnified Liabilities based in whole or in part on, or arising in whole or in
part out of, this Agreement or the transactions contemplated hereby, in each
case, to the full extent that a corporation is permitted under the DGCL to
indemnify its own directors or officers, as the case may be. In the event any
such claim, action, suit, proceeding or investigation is brought against any
Indemnified Party, the indemnifying party shall assume and direct all aspects of
the defense thereof, including settlement, and the Indemnified Party shall
cooperate in the vigorous defense of any such matter. The Indemnified Party
shall have a right to participate in (but not control) the defense of any such
matter with its own counsel and at its own expense. The indemnifying party shall
not settle any such matter unless (i) the Indemnified Party gives prior written
consent, which shall not be unreasonably withheld, or (ii) the terms of the
settlement provide that the Indemnified Party shall have no responsibility for
the discharge of any settlement amount and impose no other obligations or duties
on the Indemnified Party and the settlement discharges all rights against
Indemnified Party with respect to such matter. In no event shall the
indemnifying party be liable for any settlement effected without its prior
written consent. Any Indemnified Party wishing to claim indemnification under
this Section 6.8(b), upon learning of any such claim, action, suit, proceeding
or investigation, shall promptly notify Parent and the Surviving Corporation
(but the failure so to notify shall not relieve the indemnifying party from any
liability which it may have under this Section 6.8(b) except to the extent such
failure prejudices such indemnifying party), and shall deliver to Parent and
the Surviving Corporation the undertaking contemplated by Section 145(e) of the
DGCL. The Indemnified Parties as a group will be represented by a single law
firm with respect to each such matter unless there is, under applicable
standards of professional conduct, a conflict on any significant issue between
the positions of any two or more Indemnified Parties. The rights to
indemnification under this Section 6.8(b) shall continue in full force and
effect for a period of four years from the Effective Time; provided, however,
that all rights to indemnification in respect of any Indemnified Liabilities
asserted or made within such period shall continue until the disposition of such
Indemnified Liabilities.

          (c)     For a period of two years after the Effective Time Parent
shall cause to be maintained in effect policies of directors' and officers'
liability insurance, for the benefit of those persons who are covered by
Company's directors' and officers' liability insurance policies at the Effective
Time, providing coverage with respect to matters occurring prior to the
Effective Time that is at least equal to the coverage provided under Company's
current directors' and officers' liability insurance policies, to the extent
that such liability insurance can be maintained at an annual cost to Parent not
greater than 150 percent of the premium for the current Company directors' and
officers' liability insurance; provided that if such insurance cannot be so
maintained at such cost, Parent shall maintain as much of such insurance as can
be so maintained at a cost equal to 150 percent of the current annual premiums
of Company for such insurance.

become final and non-appealable.

          (c)     By either of Parent or Company if the consummation of the

provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such

                            CONDITIONS TO THE OFFER
     
     Capitalized terms used but not defined herein shall have the meanings set
forth in the Agreement and Plan of Merger (the "Agreement") of which this
Exhibit A is a part. Notwithstanding any other provision of the Offer and
subject to the terms of the Merger Agreement, Purchaser shall not be required to
accept for payment or, subject to any applicable rules and regulations of the
SEC, including Rule 14e-1(c) under the Exchange Act (relating to Purchaser's
obligation to pay for or return tendered Shares promptly after termination or
withdrawal of the Offer), pay for, and may delay the acceptance for payment of
or, subject to the restriction referred to above, the payment for, any tendered
Shares, and may amend the Offer consistent with the terms of the Agreement or
terminate the Offer and not accept for payment any tendered Shares, if (i) there
shall not have been validly tendered and not withdrawn prior to the expiration
of the Offer such number of Shares which, when added to the Shares, if any,
beneficially owned by Parent or Purchaser, would constitute at least a majority
of the Shares outstanding on a fully diluted basis on the date of purchase ("on
a fully-diluted basis" meaning, as of any date, the number of Shares
outstanding, together with the Shares which Company may be required to issue
pursuant to warrants, options or obligations outstanding at that date under
employee stock or similar benefit plans or otherwise whether or not vested or
then exercisable) (the "Minimum Condition"), (ii) any applicable waiting period
under the HSR Act has not expired or been terminated, or (iii) at any time on or
after the date of the Agreement and prior to the Expiration Date, any of the
following events shall occur and be continuing and shall not have resulted from
the breach by Parent or Purchaser of any of their obligations under the
Agreement:

          (a)  there shall be pending any suit, action or proceeding brought by
any third party that has a high likelihood of success on the merits or by any
Governmental Entity before any court of competent jurisdiction (i) seeking to
prohibit or impose any material limitations on Parent's or Purchaser's ownership
or operation (or that of any of their respective Subsidiaries or affiliates) of
all or a material portion of their or Company's businesses or assets, (ii)
seeking to compel Parent or Purchaser or their respective Subsidiaries and
affiliates to dispose of or hold separate any material portion of the business
or assets of Company or Parent and their respective Subsidiaries, in each case
taken as a whole, as a result of the Agreement, (iii) challenging the
acquisition by Parent or Purchaser of any Shares pursuant to the Offer, (iv)
seeking to restrain or prohibit the making or consumma-

                                      A-1
<PAGE>
 
tion of the Offer or the Merger or the performance of any of the transactions
contemplated by the Agreement, (v) seeking to obtain from Company any damages
(including damages against Company's directors or officers for which they may
seek indemnification from Company) that would be reasonably likely to have a
Material Adverse Effect on Company, (vi) seeking to impose material limitations
on the ability of Purchaser, or rendering Purchaser unable, to accept for
payment, pay for or purchase some or all of the Shares pursuant to the Offer and
the Merger, or (vii) seeking to impose material limitations on the ability of
Purchaser or Parent effectively to exercise full rights of ownership of the
Shares, including, without limitation, the right to vote the Shares purchased by
Purchaser or Parent on all matters properly presented to Company's stockholders;
or
     
               (b)  there shall be any statute, rule, regulation, judgment,
order or injunction enacted, entered, enforced, promulgated or deemed applicable
to the Offer or the Merger, or any other action shall be taken by any
Governmental Entity, other than the application to the Offer or the Merger of
applicable waiting periods under the HSR Act, that is reasonably likely to
result, directly or indirectly, in any of the consequences referred to in
clauses (i) through (vii) of paragraph (a) above; or

               (c)  (i) the representations and warranties of Company contained
in Sections 4.1(b), 4.1(u), 4.1(v), 4.1(w), 4.1(x) and the first five sentences
of Section 4.1(d) of the Agreement shall not be true and correct in all material
respects as of the date of consummation of the Offer as though made on or as of
such date (other than any such representations and warranties that by their
terms address only matters as of another specified dated, which shall be true
and correct only as of such other specified date) and (ii) all other
representations and warranties of Company contained in the Agreement, which
representations and warranties shall be deemed for purposes of this condition
not to include any qualification or limitation with respect to materiality
(whether by reference to "Material Adverse Effect" or otherwise), shall not be
true and correct as of the date of consummation of the Offer as though made on
or as of such date (other than representations and warranties that by their
terms address matters only as of another specified date, which shall be true and
correct only as of such other specified date), except in the case of this clause
(ii) where the matters in respect of which such representations and warranties
are not true and correct, in the aggregate, have not had and could not
reasonably be expected to have a Material Adverse Effect on Company, with the
same effect as though such representations and warranties were made as of the
date of consummation of the Offer; or

                                     A-2
<PAGE>
 
               (d)  there shall have occurred a Material Adverse Effect on
Company; or

               (e)  Company's Board of Directors (i) shall have withdrawn, or
modified or changed in a manner adverse to Parent or Purchaser (including by
amendment of the Schedule 14D-9) its recommendation of the Offer, the Merger
Agreement, or the Merger, (ii) shall have recommended or announced a neutral
position with respect to an Acquisition Proposal, (iii) shall have adopted any
resolution tion to effect any of the foregoing, or (iv) upon request of Parent,
shall fail to reaffirm its approval or recommendation of the Offer, the Merger
Agreement, or the Merger; or
     
               (f)  any Person or "group" (as defined in Section 13(d)(3) of the
Exchange Act), other than Parent, Purchaser or their affiliates or any group of
which any of them is a member, shall have acquired or announced its intention to
acquire (including by commencement of a tender or exchange offer) beneficial
ownership (as determined pursuant to Rule 13d-3 promulgated under the Exchange
Act) of 20% or more of the Shares; or
     
               (g)  the Merger Agreement shall have been terminated in
accordance with its terms;

which in the sole good faith judgment of Parent or Purchaser, in any such case,
and regardless of the circumstances (including any action or inaction by Parent
or Purchaser) giving rise to such condition makes it inadvisable to proceed with
the Offer and/or with such acceptance for payment of or payments for Shares.
     
               The foregoing conditions are for the sole benefit of Parent and
Purchaser and may (except for the Minimum Condition) be waived by Parent or
Purchaser, in whole or in part, at any time and from time to time, in the sole
discretion of Parent or Purchaser. The failure by Parent or Purchaser at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time.

entitled to dispose of (or to direct the disposition of) and to vote (or to
direct the voting of) 622,000 shares of common stock ("Common Stock"), par value

requested that Stockholder agree, and Stockholder has agreed, to enter into this
Agreement.

          NOW, THEREFORE, in consideration of the foregoing and the
representations, warranties, covenants and agreements contained in this
Agreement and the Merger Agreement and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound hereby, agree as follows:
   
                                   ARTICLE I
                             
                               VOTING AGREEMENT
   
          Section 1.1   Agreement to Vote Shares. During the Option Period (as
                        ------------------------
defined in Section 2.2), at any meeting of the stockholders of Company called to
consider and vote upon the adoption of the Merger Agreement (and at any and all
postponements and adjournments thereof), and in connection with any action to be
taken in respect of the adoption of the Merger Agreement by written consent of
stockholders of Company, Stockholder shall vote or cause to be voted (including
by written consent, if applicable) all of the Subject Shares, now owned or
hereafter acquired, in favor of the adoption of the Merger Agreement and in
favor of any other matter necessary for the consummation of the transactions
contemplated by the Merger Agreement and considered and voted upon at any such
meeting or made the subject of any such written consent, as applicable. During
the Option Period, at any meeting of the stockholders of Company called to
consider and vote upon any Other Proposal (as hereinafter defined) (and at any
and all postponements and adjournments thereof), and in connection with any
action to be taken in respect of any Other Proposal by written consent of
stockholders of Company, Stockholder shall vote or cause to be voted (including
by written consent, if applicable) all of the Subject Shares against such Other
Proposal. For purposes of this Agreement, the term "Other Proposal" means any
(a) Acquisition Proposal (as defined in the Merger Agreement) or (b) other
action which is intended or could reasonably be expected to materially impede,
interfere with, delay or materially and adversely affect the consummation of the
Merger or any of the other transactions contemplated by the Merger Agreement or
this Agreement; provided, however, that neither the Merger nor any other
transaction contemplated by the Merger Agreement to be consummated by Company,
Parent or Purchaser in connection with the Merger shall constitute an Other
Proposal. Stockholder shall not enter into any agreement or understanding with
any person or entity the effect of which would be violative of the provisions
and agreements contained in this Section 1.1.

               --------------
DESIGNEE OF PARENT, EACH OF THEM INDIVIDUALLY, STOCKHOLDER'S PROXY AND ATTORNEY-
IN-FACT PURSUANT TO THE PROVISIONS OF SECTION 212 OF THE DELAWARE GENERAL
CORPORATION LAW, WITH FULL POWER OF SUBSTITUTION AND RESUBSTITUTION, TO VOTE OR
ACT BY WRITTEN CONSENT DURING THE OPTION PERIOD WITH RESPECT TO THE SUBJECT
SHARES IN ACCORDANCE WITH SECTION 1.1 HEREOF. THIS PROXY IS GIVEN TO SECURE THE

AFFIRMS THAT THIS PROXY IS COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE.
STOCKHOLDER SHALL TAKE SUCH FURTHER ACTION OR EXECUTE SUCH OTHER INSTRUMENTS AS
MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY.
   
          (b)  Other Proxies Revoked. Stockholder represents that any proxies
               ---------------------
heretofore given in respect of the Subject Shares are not irrevocable, and that
all such proxies are hereby revoked.

                                    OPTION
   
          Section 2.1   Grant of Option. Stockholder hereby grants to Parent an
                        ---------------
irrevocable option (the "Option") to purchase the Subject Shares on the terms
and subject to the conditions set forth herein, at a price per Subject Share
equal to $7.00 in cash or any higher price that Parent or any controlled
affiliate of Parent offers to pay for the shares of Common Stock of the Company
made generally to the stockholders of the Company (such price being referred to

          Section 2.2   Exercise of Option. (a) Parent may exercise the Option,
                        ------------------
in whole or in part, at any time or from time to time during the period (the
"Option Period") from and including the date hereof through and including the
earlier of (i) the date that is 120 days after the purchase of shares of common
stock of the Company pursuant to the Offer, (ii) the date that is 120 days after
the date on which the Merger Agreement is terminated pursuant to Sections
8.1(d)(i) or (e)(i) thereof, (iii) the date that

                                       3
<PAGE>
 
is 30 days after the date on which the Merger Agreement is terminated pursuant
to Section 8.1(e)(v), and (iv) the date on which the Merger Agreement is
terminated if such termination is other than pursuant to Sections 8.1(d)(i),
(e)(i) or (e)(v) thereof; provided, however, that the Option shall terminate
                          --------  -------
with respect to any Subject Shares that are tendered pursuant to the Offer and
purchased by Purchaser thereunder. Notwithstanding anything in this Agreement to
the contrary, Parent shall be entitled to purchase all Subject Shares in respect
of which it shall have exercised the Option in accordance with the terms hereof
prior to the expiration of the Option Period, and the expiration of the Option
Period shall not affect any rights hereunder which by their terms do not
terminate or expire prior to or as of such expiration.
   
          (b)  Parent shall not demand appraisal rights under Section 262 of the
DGCL in respect of any Subject Shares.
   
          (c)  If Parent wishes to exercise the Option, it shall deliver to
Stockholder a written notice (an "Exercise Notice") to that effect which
specifies (i) the number of Subject Shares to be purchased from Stockholder and
(ii) a date (an "Option Closing Date") not earlier than three business days
after the date such Exercise Notice is delivered for the consummation of the
purchase and sale of such Subject Shares (an "Option Closing"). If and to the
extent necessary to deliver the number of Shares to be purchased pursuant
hereto, Stockholder shall exercise vested stock options promptly upon receipt of
an Exercise Notice. If the Option Closing cannot be effected on the Option
Closing Date specified in the Exercise Notice by reason of a preliminary or
final injunction or any other applicable judgment, decree, order, law or
regulation, or because any applicable waiting period under the HSR Act shall not
have expired or been terminated, (i) Stockholder shall promptly take all such
actions as may be reasonably requested by Parent, and shall otherwise fully
cooperate with Parent, to cause the elimination of all such impediments to the
Option Closing and, (ii) the Option Closing Date specified in the Exercise
Notice shall be extended to the fifth business day following the elimination of
all such impediments. The place of the Option Closing shall be at the offices of
Skadden, Arps, Slate, Meagher & Flom LLP, Four Embarcadero Center, San
Francisco, California 94111, and the time of the Option Closing shall be 10:00
a.m. (New York Time) on the Option Closing Date.

                                                                    --------
however, that the Option shall terminate (x) with respect to any Subject Shares
- -------
that are tendered pursuant to the Offer and purchased by Purchaser thereunder,
(y) if the Merger Agreement is terminated pursuant to Section 8.1(d)(iv) thereof
and at the time of such termination Company is not in breach of the Merger
Agreement, and (z) if the Merger Agreement is terminated solely because the
condition contained in Section 7.1(d) of the Merger Agreement is incapable of
being fulfilled. Notwithstanding anything in this Agreement to the contrary,
Parent shall be entitled to purchase all Subject Shares in respect of which it
shall have exercised the Option in accordance with the terms hereof prior to the

not affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such expiration.

     (b)   Parent shall not demand appraisal rights under Section 262 of the

purchase and sale of such Subject Shares (an "Option Closing"). If and to the
extent necessary to deliver the number of Shares to be purchased pursuant

an Exercise Notice. If the Option Closing cannot be effected on the Option
Closing Date specified in the Exercise Notice by reason of a preliminary or
final injunction or any other applicable judgment, decree, order, law or
regulation, or because any applicable waiting period under the HSR Act shall not
have expired or been terminated, (i) Stockholder shall promptly take all such
actions as may be reasonably requested by Parent, and shall otherwise fully
cooperate with Parent, to cause the elimination of all such impediments to the
Option Closing and (ii) the Option Closing Date specified in the Exercise Notice
shall be extended to the fifth business day following the elimination of all
such impediments. The place of the Option Closing shall be at the offices of
Skadden, Arps, Slate, Meagher & Flom LLP, Four Embarcadero Center, San

Stockholder shall deliver to Parent such Subject Shares, free and clear of all
Liens, with the certificate or certificates evidencing such Subject Shares being
duly endorsed for transfer by Stockholder and accompanied by all powers of
attorney and/or other instruments necessary to convey valid and unencumbered

dividend, split-up, merger, recapitalization, combination, exchange of shares,
extraordinary distribution or similar transaction, the type and number or amount
of shares, securities or other property subject to the Option, and the Option
Consideration payable therefor, shall be adjusted appropriately so that Parent

                  A. Parent, Purchaser and Interlink Computer Sciences, Inc., a

                  B. As of the date hereof, Stockholder beneficially owns and is
entitled to dispose of (or to direct the disposition of) and to vote (or to

Stockholder during the period from and including the date hereof through and
including the earlier of (i) the Effective Time and (ii) the date that is 120

                  C. Pursuant to the Merger Agreement, Purchaser shall commence
a cash tender offer (the "Offer") to purchase at a price of $7.00 per Share all

willingness to enter into the Merger Agreement, Parent and Purchaser have
requested that Stockholder agree, and Stockholder has agreed, to enter into this
Agreement.

                  NOW, THEREFORE, in consideration of the foregoing and the
representations, warranties, covenants and agreements contained in this
Agreement and the Merger Agreement and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound hereby, agree as follows:

                                   ARTICLE I

                               VOTING AGREEMENT

                  Section 1.1 Agreement to Vote Shares. During the period (the
                              ------------------------
"Voting Period") from and including the date hereof through and including the
earlier of (i) the date that is 120 days after the purchase of shares of common
stock of the Company pursuant to the Offer, (ii) the date that is 120 days after
the date on which the Merger Agreement is terminated pursuant to Section 8.1
thereof, or (iii) the termination of this Agreement pursuant to Section 5.2
hereof, at any meeting of the stockholders of Company called to consider and
vote upon the adoption of the Merger Agreement (and at any and all postponements
and adjournments thereof), and in connection with any action to be taken in
respect of the adoption of the Merger Agreement by written consent of
stockholders of Company, Stockholder shall vote or cause to be voted (including
by written consent, if applicable) all of the Subject Shares, now owned or
hereafter acquired, in favor of the adoption of the Merger Agreement and in
favor of any other matter necessary for the consummation of the transactions
contemplated by the Merger Agreement and considered and voted upon at any such
meeting or made the subject of any such written consent, as applicable. During
the Voting Period, at any meeting of the stockholders of Company called to
consider and vote upon any Other Proposal (as hereinafter defined) (and at any
and all postponements and adjournments thereof), and in connection with any
action to be taken in respect of any Other Proposal by written consent of
stockholders of Company, Stockholder shall vote or cause to be voted (including
by written consent, if applicable) all of the Subject Shares against such Other
Proposal. For purposes of this Agreement, the term "Other Proposal" means any
(a) Acquisition Proposal (as defined in the Merger Agreement) or (b) other
action which is intended or could reasonably be expected to materially impede,
interfere with, delay or materially and adversely affect the consummation of the
Merger or any of the other transactions

contemplated by the Merger Agreement or this Agreement; provided, however, that
neither the Merger nor any other transaction contemplated by the Merger
Agreement to be consummated by Company, Parent or Purchaser in connection with
the Merger shall constitute an Other Proposal. Stockholder shall not enter into
any agreement or understanding with any person or entity the effect of which
would be violative of the provisions and agreements contained in this Section
1.1.

                  Section 1.2 Irrevocable Proxy.
                              -----------------

                  (a) Grant of Proxy. STOCKHOLDER HEREBY APPOINTS PARENT AND ANY
                      --------------

INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY.

                  (b) Other Proxies Revoked. Stockholder represents that any
                      ---------------------
proxies heretofore given in respect of the Subject Shares are not irrevocable,
and that all such proxies are hereby revoked.


                                  ARTICLE II

                                    OPTION

                  Section 2.1 Grant of Option. Stockholder hereby grants to
                              ---------------
Parent an irrevocable option (the "Option") to purchase the Subject Shares on
the terms and subject to the conditions set forth herein, at a price per Subject

                  Section 2.2 Exercise of Option. (a) Parent may exercise the
                              ------------------
Option, in whole or in part, at any time or from time to time during the period
(the "Option Period") from and including the date hereof through and including
the earlier of (i) the date that is 120 days after the purchase of shares of
common stock of the Company pursuant to the Offer, or (ii) the date that the
Merger Agreement is terminated pursuant to Section 8.1 thereof, provided,
                                                                --------
however, that the Option shall terminate with respect to any Subject Shares that
- -------
are tendered pursuant to the Offer and purchased by Purchaser thereunder.
Notwithstanding anything in this Agreement to the contrary, Parent shall be
entitled to purchase all Subject Shares in respect of which it shall have
exercised the Option in accordance with the terms hereof prior to the expiration
of the Option Period, and the expiration of the Option Period shall not affect
any rights hereunder which by their terms do not terminate or expire prior to or
as of such expiration.

                  (b) Parent shall not demand appraisal rights under Section 262
of the DGCL in respect of any Subject Shares.

                  (c) If Parent wishes to exercise the Option, it shall deliver
to Stockholder a written notice (an "Exercise Notice") to that effect which
specifies (i) the number of Subject Shares to be purchased from Stockholder and
(ii) a date (an "Option Closing Date") not earlier than three business days
after the date such Exercise Notice is delivered for the consummation of the
purchase and sale of such Subject Shares (an "Option Closing"). If and to the
extent necessary to deliver the number of Shares to be purchased pursuant
hereto, Stockholder shall exercise vested stock options promptly upon receipt of
an Exercise Notice. If the Option Closing cannot be effected on the Option
Closing Date specified in the Exercise Notice by reason of a preliminary or
final injunction or any other applicable judgment, decree, order, law or
regulation, or because any applicable waiting period under the HSR Act shall not
have expired or been terminated, (i) Stockholder shall promptly take all such
actions as may be reasonably requested by Parent, and shall otherwise fully
cooperate with Parent, to cause the elimination of all such impediments to the
Option Closing and (ii) the Option Closing Date specified in the Exercise Notice
shall be extended to the fifth business day following the elimination of all
such impediments. The place of the Option Closing shall be at the offices of
Skadden, Arps, Slate, Meagher & Flom LLP, Four Embarcadero Center, San
Francisco, California 94111, and the time of the Option Closing shall be 10:00
a.m. (New York Time) on the Option Closing Date.

                              ------------------------------------
Option Closing, Parent shall pay to Stockholder the Option Consideration payable
in respect of the Subject Shares to be purchased from Stockholder at the Option
Closing, and Stockholder shall deliver to Parent such Subject Shares, free and
clear of all Liens, with the certificate or certificates evidencing such Subject
Shares being duly endorsed for transfer by Stockholder and accompanied by all
powers of attorney and/or other instruments necessary to convey valid and
unencumbered title thereto to Parent, and shall, to the extent permissible,
assign to Parent (pursuant to a written instrument in form and substance
satisfactory to Parent) all rights that Stockholder may have to require Company
to register such Subject Shares under the Securities Act. Transfer taxes, if
any, imposed as a result of the exercise of the Option shall be borne by
Stockholder.

                  Section 2.4 Adjustment upon Changes in Capitalization, Etc. In
                              ----------------------------------------------
the event of any change in the capital stock of Company by reason of a stock
dividend, split-up, merger, recapitalization, combination, exchange of shares,
extraordinary distribution or similar transaction, the type and number or amount
of shares, securities or other property subject to the Option, and the Option
Consideration payable therefor, shall be adjusted appropriately so that Parent
shall receive upon exercise of Option the type and number or amount of shares,
securities or property that Parent would have retained and/or been entitled to
receive in respect of the Subject Shares if the Option had been exercised
immediately prior to such event relating to Company or the record date therefor,
as applicable. The provisions of this Section 2.4 shall apply in a like manner
to successive stock dividends, split-ups, mergers, recapitalizations,
combinations, exchanges of shares or extraordinary distributions or similar

jurisdiction by motion or other request for leave from any such court, and (iii)
shall not bring any action relating to this Agreement or any of the transactions
contemplated hereby in any court other than the Court of Chancery in and for New

jurisdiction, any appropriate state or federal court in New Castle County in the
State of Delaware).

                               ------------
or portion of any provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law but if any provision or
portion of any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or portion of any provision in such jurisdiction, and this
Agreement shall be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision or portion of any provision had
never been contained herein.

                                                                    NEWS RELEASE

                         STERLING SOFTWARE TO ACQUIRE

                          INTERLINK COMPUTER SCIENCES
                                
     DALLAS, TX and FREMONT, CA, March 24, 1999 - Sterling Software, Inc. (SSW-
NYSE), one of the 20 largest independent software companies in the world, today
announced that it had entered into a definitive agreement to acquire Interlink
Computer Sciences, Inc. (INLK-NASDAQ), a leading supplier of high-performance
solutions for enterprise systems networking, headquartered in Fremont,
California. The transaction is valued at approximately $64 million (net of
exercise proceeds from outstanding options and warrants) and will be structured
as a $7.00 per share first-step cash tender offer, followed by a second-step
merger at the same price per share. The companies anticipate closing the
acquisition in late April or early May 1999 and at that time combining
Interlink's business with Sterling Software's worldwide network management
business.                                

     Interlink's software solutions allow enterprise servers to inter-operate
with TCP/IP networks and enable customers to provide secure, managed access to
their enterprise applications and data over public and private connections.
These offerings are in direct support of growing customer requirements to allow
internal and external access to their enterprise servers, where most enterprise-
scale applications continue to reside, for e-commerce and other network-centric
business strategies.

     "This acquisition brings us tremendous opportunities to strengthen our
strategic position in the marketplace and capitalize on the explosive growth of
the Internet as a cost-effective, open network for enterprise computing," said
Sterling L. Williams, president and chief executive officer of Sterling
Software. "With the addition of Interlink's network management technology, we
will be able to extend our lead in OS/390 TCP/IP management and enhance our
ability to manage specific applications running on TCP/IP networks. This
acquisition also gives us a significant customer base and an excellent
opportunity to leverage our SOLVE family of network management products."
<PAGE>
 
     Mr. Williams noted that, when completed, this will be Sterling Software's
33rd acquisition     and the second systems management acquisition announced 
in less than three weeks. Earlier this month, the company announced it was
acquiring the storage management software business of Spectra Logic Corporation.
He added the acquisition of Interlink would be accretive to earnings per share.

     A.J. Berkeley, president and chief executive officer of Interlink, said:
"Interlink's software solutions are a perfect fit with Sterling Software's
network management products. Sterling Software will be able to broaden its
TCP/IP network management solutions, and Interlink's products will now reach the
very large corporations that need the performance and reliability that our
products provide. With our common heritage and focus, I think this union will
produce one of the best network management teams in the world. I am excited for
our customers and employees."

     Under the merger agreement, Sterling Software will commence a first-step
tender offer to purchase all outstanding shares of Interlink for $7.00 per share
in cash. Following completion of the tender offer, Interlink would be merged
with a wholly-owned subsidiary of Sterling Software and the remaining Interlink
shares would be converted into the right to receive $7.00 per share. The tender
offer and merger were unanimously approved by Interlink's Board of Directors.
The tender offer is scheduled to commence on or prior to March 30, 1999.

     In connection with the merger agreement, Sterling Software has entered into
Stockholder Agreements with certain major stockholders of Interlink owning an
aggregate of approximately 19.7% of Interlink's shares, calculated on a fully-
diluted basis, under which such stockholders have, among other things, granted
Sterling Software an option to purchase their shares at a price of $7.00 per
share.

     The tender offer will be conditioned, among other things, on the valid
tender of Interlink shares which, together with shares subject to the
Stockholder Agreements or owned by Sterling Software, represent a majority of
Interlink's outstanding shares on a fully diluted basis, and the expiration or
termination of the Hart-Scott-Rodino Act's waiting period.

     Interlink Computer Sciences, Inc. is an international supplier of solutions
that enable its customers to securely manage and control their business

networks. The company's products and services focus on TCP/IP-centric operations
in the data center that enable customers to securely use their IBM and IBM-
compatible OS/390 mainframes as "enterprise servers" in distributed,
heterogeneous client/server network environments. For the fiscal year ended June
30, 1998, Interlink reported revenues of $29 million. For more information, you

To Our Stockholders:
 
   On behalf of the Board of Directors of Inerlink Computer Sciences, Inc.
(the "Company"), we are pleased to inform you that on March 23, 1999, the
Company entered into an Agreement and Plan of Merger (the "Merger Agreement")
with Sterling Software, Inc. and Sterling Software (Southwest), Inc., its
indirect, wholly owned subsidiary, pursuant to which Sterling Software
(Southwest), Inc. today has commenced a cash tender offer (the "Offer") to
purchase all of the outstanding shares (the "Shares") of the Common Stock of
the Company at $7.00 per share. Under the Merger Agreement, the Offer will be
followed by a merger (the "Merger") in which any remaining shares of the
Common Stock of the Company will be converted into the right to receive $7.00
per share in cash, without interest (except any Shares as to which the holder
has properly exercised dissenter's rights of appraisal). Stockholders owning
or having options to acquire approximately 19.7% of the Company's outstanding
Shares on a fully dilated basis have agreed to tender their Shares in the
Offer.
 
   Your Board of Directors has unanimously determined that the Offer and
Merger are fair and in the best interests of the Company and its stockholders
and has approved the Offer and Merger; and the Board of Directors recommends
that the stockholders of the Company accept the Offer and tender their Shares
pursuant to the Offer.
 
   In arriving at its recommendation, the Board of Directors gave careful
consideration to the factors described in the attached
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
that is being filed today with the Securities and Exchange Commission. Among
other things, the Board of Directors considered the opinion of its financial
advisor, Hambrecht & Quist LLC, that the consideration to be received by the
holders of Shares in the Offer and Merger is fair to such holders from a
financial point of view.
 
   In addition to the attached Schedule 14D-9, enclosed also is the Offer to
Purchase dated March 30, 1999, together with related materials, including a
Letter of Transmittal to be used for tendering your certificates representing
Shares in the Offer. These documents state the terms and conditions of the
Offer and the Merger and provide instructions as to how to tender your Shares.
We urge you to read these documents carefully in making your decision with
respect to tendering your shares pursuant to the Offer.
 
                                          On behalf of the Board of Directors,
 
                                          /s/ Augustus J. Berkeley

          Re:  Potential Acquisition Transaction
               ---------------------------------

Gentlemen:
     
          This letter is to confirm certain agreements we have reached regarding
the potential acquisition (the "Potential Acquisition") by Sterling Software,
Inc. ("Sterling Software") of Interlink Computer Sciences, Inc. ("Interlink").
As a material inducement to Sterling Software's continuation of negotiations
with Interlink with respect to the terms and conditions of the Potential
Acquisition, and in consideration of the mutual covenants contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto hereby agree as follows:
     
               1.   Exclusivity Period. Upon the execution of this letter
                    ------------------
agreement and continuing until the earlier of (a) 6:00 p.m. California time on
March 25, 1999 and (b) the execution of a definitive agreement governing the
terms and conditions of the Potential Acquisition (such period, the "Exclusivity
Period"), Interlink shall, shall cause its subsidiaries to, and shall use
reasonable efforts to cause all of its or their affiliates, officers, directors,
employees, agents and representatives (including without limitation any
investment banker, financial advisor, attorney and accountant retained by
Interlink or any of its subsidiaries or affiliates) to, discontinue any
solicitation efforts, discussions or negotiations with respect to any
Acquisition Proposal (as hereinafter defined) with any person or entity other
than Sterling Software. During the Exclusivity Period, Interlink shall not, and
shall not authorize or permit any of its subsidiaries or any of its or their
affiliates, officers, directors, employees, agents or representatives (including
without limitations any investment banker, financial advisor, attorney or
accountant retained by Interlink or any of its subsidiaries or affiliates) to,
directly or indirectly, initiate, solicit or intentionally encourage (including
by way of furnishing information or assistance), or take any other action to
facilitate, any inquiries, any expression of interest or the making of any
proposal that constitutes, or would reasonably be expected to lead to, an
Acquisition Proposal, or enter into or maintain or continue discussions or
negotiate with any person in furtherance of such inquiries or to seek to obtain
an Acquisition Proposal or agree to or endorse any Acquisition Proposal.

Interlink shall notify Sterling Software immediately if any such inquiries,
expressions of interest or proposals are received by, any such information is
requested from, or any such negotiations or discussions are sought to be
initiated or continued with Interlink or any of its subsidiaries, affiliates,
agents or representatives; provided, however, that Interlink's obligation under
this and the immediately succeeding two sentences shall only be applicable to
such of the foregoing as (i) involve any items of non-cash consideration other
than securities for which there is an existing public market ("Marketable
Securities"), or (ii) involve aggregate consideration consisting of cash and/or
Marketable Securities in exchange for all of Interlink's outstanding shares of
common stock, such consideration having a value per share of $7.00 or greater
(each, a "Superior Proposal"). Such notice shall include the identity of the
party making, and the terms of (including delivery of copies thereof), any
inquiry or proposal relating to a Superior Proposal. Interlink will keep
Sterling Software fully informed of the status of, and any modification to, any
Superior Proposal. For purposes of this letter agreement, "Acquisition Proposal"
means an inquiry, offer, proposal or other indication of interest (other than by
Sterling Software in connection with the Potential Acquisition) regarding any of
the following matters involving Interlink: (i) any merger, consolidation, share
exchange, tender or exchange offer, recapitalization, business combination or
other similar transaction immediately following the consummation of which, the
stockholders of Interlink immediately prior thereto would hold less than 80% of
the voting stock of the surviving or resulting entity; (ii) any acquisitions of
voting stock or other securities issued by Interlink or any of its subsidiaries
representing more than 80% of the outstanding voting stock of Interlink or any
of its subsidiaries; (iii) any sale, lease, exchange, mortgage, pledge, transfer
or other disposition of all or substantially all of the assets of Interlink and
its subsidiaries, taken as a whole, in a single transaction or series of related
transactions; or (iv) any agreement in principle or other agreement to engage in
any of the foregoing.
     
          2.   Certain Obligations Only on Definitive Agreement. No agreement
               ------------------------------------------------
providing for the Potential Acquisition shall be deemed to exist unless and
until definitive documentation providing therefor has been executed and
delivered by Sterling Software and Interlink (and/or any other appropriate party
or parties thereto). Unless and until such definitive documentation concerning a
Potential Acquisition has been executed, neither Sterling Software nor any of
our representatives will have any liability to Interlink with respect to a
Potential Acquisition, whether by virtue of this letter agreement or otherwise.
     
          3.   Non-Solicitation of Employees. Sterling Software agrees that for
               -----------------------------
a period of one year from the date of this letter agreement, it will not,
directly or
<PAGE>
 
Interlink Computer Sciences, Inc.

indirectly, solicit for employment or attempt to hire or recruit any employee of
Interlink (or any subsidiary thereof) with whom Sterling Software has had
contact or who became known to Sterling Software in connection with Sterling
Software's consideration of the Potential Acquisition. Notwithstanding anything
to the contrary herein, Sterling Software shall not be deemed to have breached
or violated this paragraph 3 solely (a) as a result of generic employment
advertising by Sterling Software (including, without limitation, "open position"
and similar listings in Sterling Software's various World Wide Web pages), (b)
as a result of the efforts of an executive recruitment or similar firm generally
engaged to recruit employees for Sterling Software (without targeting of
Interlink or its specific employees) or (c) if any employee of Interlink (or any
subsidiary thereof) approaches and obtains employment with Sterling Software
after the date hereof solely as a result of any advertising or recruitment
effort contemplated in clause (a) or (b) above.
     
          4.   General Provisions. No failure or delay in exercising any right
               ------------------
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any other right. This letter agreement shall be binding on and inure to the
benefit of the parties hereto and their respective successors and assigns,
although neither party may assign any of its rights or obligations hereunder
without the prior written consent of the other party, which consent may be
withheld in the sole and absolute discretion of such other party. Money damages
would not be a sufficient remedy for any breach or violation of the terms of
this letter agreement and, accordingly, Sterling Software or Interlink, as the
case may be, shall be entitled to specific performance and injunctive relief as
remedies for any breach or violation, in addition to all other remedies
available at law or equity. This letter agreement may not be amended except by
virtue of a written instrument executed by both of the parties hereto. This
letter agreement shall be governed by and construed in accordance with the laws
of the State of Delaware, without giving effect to the principles of conflict of
laws thereof.

agreement, all severance benefits whether provided for in such Employment
Agreement or otherwise, except as otherwise provided in Section 3(b) herein.

     3.  Services and Compensation.
         --------------------------

         (a) Consultant agrees to perform for the Company the services
("Services") described in Exhibit A, attached hereto, until the expiration of
                          ---------                                          
this Agreement as provided in Section 4 herein.

         (b) Notwithstanding any provision to the contrary in the 1992 Stock
Plan or the Consultant's Stock Option Agreements, the unvested portion of all

<PAGE>
 
"Closing"), or (ii) upon the signing of a definitive acquisition agreement
for the sale of the Company to any other entity during the term of this
Agreement.  Any vested stock options (including any Unvested Options that vest
pursuant hereto) held by Consultant shall remain exercisable until the later of
either (i) the date specified for Consultant's option pursuant to the 1992 Stock
Plan, or (ii) thirty (30) days after the Merger Agreement among Sterling,

pursuant hereto).

     4.  Term.
         ----  

         This Agreement will commence on the date hereof and will continue for

     5.  Assignment.
         ---------- 

         Neither this Agreement nor any right hereunder or interest herein may
be assigned or transferred by Consultant without the express written consent of
the Company.

     6.  Independent Contractor.
         ---------------------- 

         It is the express intention of the parties that Consultant is an
independent contractor.  Nothing in this Agreement shall in any way be construed
to constitute Consultant as an agent, employee or representative of the Company,
but Consultant shall perform the Services hereunder as an independent
contractor.  Consultant agrees to furnish (or reimburse the Company for) all
tools and materials necessary to accomplish this contract, and shall incur all
expenses associated with performance, except as expressly provided on Exhibit A
                                                                      ---------
of this Agreement.  Consultant acknowledges and agrees that Consultant is
obligated to report as income all compensation received by Consultant pursuant
to this Agreement, and Consultant agrees to and acknowledges the obligation to
pay all self-employment and other taxes thereon.  Consultant further agrees to
indemnify and hold harmless the Company and its directors, officers, and
employees from and against all taxes, losses, damages, liabilities, costs and
expenses, including attorney's fees and other legal expenses, arising directly
or indirectly from (i) any negligent, reckless or intentionally wrongful act of
Consultant or Consultant's assistants, employees or agents, (ii) a determination
by a court or agency that the Consultant is not an independent contractor, or
(iii) any breach by the Consultant or Consultant's assistants, employees or
agents of any of the covenants contained in this Agreement.

     7.  Benefits.
         -------- 

         Consultant acknowledges and agrees and it is the intent of the parties
hereto that Consultant receive no Company-sponsored benefits from the Company
either as a Consultant or employee, other than (i) any indemnification 
arrangements that Consultant has with the Company or (ii) any D&O insurance
coverage applicable to the Consultant in any of his capacities related to the
Company. Such benefits include, but are not limited to, paid vacation, sick
leave, medical insurance and 401(k) participation. Notwithstanding the above,
If Consultant is eligible for and timely elects 
<PAGE>
 
group health continuation coverage pursuant to the Consolidated Omnibus
Reconciliation Act of 1985, as amended ("COBRA"), the Company will reimburse
Consultant for his COBRA premiums until the earlier of (i) April 30, 1999; or
(ii) the date Consultant is no longer eligible to receive continuation
coverage pursuant to COBRA. Consultant shall thereafter be responsible for the
payment of COBRA coverage at 102% of the actual premium cost for the remaining
COBRA period. If Consultant is reclassified by a state or federal agency or
court as an employee, Consultant will become a reclassified employee and will
receive no benefits except those mandated by state or federal law, even if by
the terms of the Company's benefit plans in effect at the time of such
reclassification Consultant would otherwise be eligible for such benefits.

or controversy.  The decision of the arbitrator shall be final, conclusive and
binding on the parties to the arbitration.  Judgment may be entered on the
arbitrator's decision in any court of competent jurisdiction.

proceeding arising from or relating to this Agreement or relating to any
arbitration in which the parties are participants.

         (c) Equitable Relief.  The parties may apply to any court of competent
             ----------------

 (1) This column shows the hypothetical gains or "option spreads" of the options
     granted based on assumed annual compound stock appreciation rates of 5% and
     10% over the full seven-year term of the options. The 5% and 10% assumed
     rates of appreciation are mandated by the rules of the Securities and
     Exchange Commission and do not represent the Company's estimate or
     projection of future Common Stock prices. The gains shown are net of the
     option exercise price, but do not include deductions for taxes or other
     expenses associated with the exercise of the option or the sale of the
     underlying shares. The actual gains, if any, on the exercise of stock
     options will depend on the future performance of the Common Stock, the
     option holder's continued employment through the option period, and the
     date on which the options are exercised.

 (2) Options vest as of 9/48th of the option shares after nine months from the
     vesting commencement date and as to 1/48th of the option shares each month
     thereafter, with full vesting occurring on the fourth anniversary of the
     vesting commencement date.
 (3) Options were granted at an exercise price equal to the fair market value of
     the Company's Common Stock. Exercise price may be paid in cash, promissory
     note, by delivery of already-owned shares subject to certain conditions, or
     pursuant to a cashless exercise procedure under which the optionee provides
     irrevocable instructions to a brokerage firm to sell the purchased shares
     and to remit to the Company, out of the sale proceeds, an amount equal to
     the exercise price plus all applicable withholding taxes.
 (4) Option was granted under the 1996 Director option plan at an exercise price
     equal to the fair market value of the Company's Common Stock on the date of
     grant.  Options vest as to 1/48th of the option shares each month, with
     full vesting occurring on the fourth anniversary of the vesting
     commencement date.  These options expire ten years from the date of grant.
 (5) Option was granted under an agreement between Mr. Braniff and the Company,
     whereby Mr. Braniff was to act as Interim Chief Executive Officer until a
     full-time Chief Executive Officer was hired.  Options vest as to 1/12th of
     the option shares each month, with full vesting occurring on the
     anniversary of the vesting commencement date.  Options are also subject to
     certain acceleration clauses.
 (6) Options vest as to 1/84th of the option shares each month with full vesting
     occurring on the seventh anniversary of the vesting commencement date.
     According to the terms of these grants, if the average share price in
     effect on the grant date doubles and the increased price is sustained over
     a one month period, the options will accelerate their vesting by one year.
     Thereafter, an additional year of vesting will accelerate for every $5 of
     incremental value added to the Company's average stock.  The stock must
     retain its increased value over a one month period in order for any
     acceleration of options to occur.  The performance based option grant will
     carry a two year minimum vesting schedule regardless of acceleration
     factors.

EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS

     Mr. Berkeley and Mr. Barth each have entered into letter agreements with
the Company which provide for severance payments if they are terminated without
cause.  Mr. Berkeley will be entitled to severance payments equal to twelve
months salary, Mr. Barth will be entitled to severance payments equal to six
months salary. All of the Named Executive Officers' employment with the Company
is terminable at will.  In addition, each of the Named Executive Officers has
entered into a change of control severance agreement which provides for
acceleration of all unvested stock options and/or restricted stock held by such
officer upon an involuntary termination without cause of such officer within
twelve (12) months of a change of control transaction.


DIRECTOR COMPENSATION

     Members of the Company's Board of Directors that are employees of the
Company do not receive compensation for their services as directors. The
Company's 1996 Director Option Plan provides that options will be granted to
non-employee directors of the Company pursuant to an automatic nondiscretionary
grant mechanism. Upon joining the Board of Directors, each new non-employee
director will automatically be granted an option to purchase 15,000 shares of
Common Stock and each non-employee director will subsequently be granted an
additional option to purchase 3,750 shares of Common Stock annually, each such
option to be granted at the fair market value of the Common Stock on the date of
grant. The initial option grant of 15,000 shares vests at a rate of 1/48th of
the shares per month following the date of grant, and the subsequent option
grant of 3,750 shares vests at the end of four years.  In addition, the Company
reimburses the reasonable travel expenses of the directors.

REPORT OF THE COMPENSATION COMMITTEE

     The following is the Report of the Compensation Committee of the Company
describing the compensation policies and rationale applicable to the Company's
executive officers with respect to the compensation paid to such executive
officers for the fiscal year ended June 30, 1998. The information contained in
the report shall not be deemed to be "soliciting material" or to be "filed" with
the Securities and Exchange Commission nor shall such information be
incorporated by reference into any future filing under the Securities Act of
1933, as amended, or the Securities Exchange Act of 1934, as amended, except to
the extent that the Company specifically incorporates it by reference into such
filing.

     General. The responsibilities of the Compensation Committee are to
administer the Company's various incentive plans, including the Company's 1992
Stock Option Plan and the 1996 Employee Stock Purchase Plan, and to set
compensation policies applicable to the Company's executive officers. The
Committee's fundamental policy is to offer the Company's executive officers
competitive compensation opportunities based upon overall Company performance,
their individual contribution to the financial success of the Company and their
personal performance. It is the Committee's objective to have a substantial
portion of each officer's compensation contingent upon the Company's
performance, as well as upon such officer's own level of performance.
Accordingly, each executive officer's compensation package comprises three
elements: (i) base salary, which is established primarily on the basis of
individual performance and market considerations; (ii) annual variable
performance awards payable in cash and tied to the Company's achievement of
financial performance goals and the executive's contribution; and (iii) long-
term stock-based incentive awards, which strengthen the mutuality of interests
between the executive officers and the stockholders.

     Base Salary. Base salary is primarily used by the Company as a device to
attract, motivate, reward and retain highly skilled executives. The Committee
reviewed and approved fiscal year 1998 base salaries for the Chief Executive
Officer and other executive officers at the beginning of the fiscal year or at
the date of their appointment. Base salaries were established by the Committee
based on an executive officer's job responsibilities, level of experience,
individual performance, contribution to the business, the Company's financial
performance for the past year and recommendations from management. The Committee
also took into 

                                      -5-
<PAGE>
 
account the salaries for similar positions at comparable companies, based on
each individual Committee member's industry experience. In reviewing base
salaries, the Committee focused significantly on each executive officer's prior
performance with the Company and expected contribution to the Company's future
success. In making base salary decisions, the Committee exercised its discretion
and judgment using these factors. No specific formula was applied to determine
the weight of each factor.

     Annual Incentive Bonuses. Each executive officer's bonus is based on
qualitative and quantitative factors. Bonuses are intended to motivate and
reward executive officers by directly linking the amount of the bonus to
specific Company-based performance targets. Annual incentive bonuses for
executive officers are intended to reflect the Committee's belief that a portion
of the compensation of each executive officer should be contingent upon the
performance of the Company. To carry out this philosophy, the Board reviews and
approves the financial budget for the fiscal year. The Committee then
establishes target bonuses for each executive officer as a percentage of the
officer's base salary. The executive officers, must successfully achieve these
performance targets, which are submitted by management to the Committee for its
evaluation and approval at the beginning of the fiscal year. Company-based
performance goals are tied to different indicators of Company performance, such
as the operating results of the Company. The Committee evaluates the completion
of the Company-based performance targets and approves a performance rating
relative to the goals completed. This scoring is influenced by the Committee's
perception of the importance of the various corporate goals. The Committee
believes that the bonus arrangement provides an excellent link between the
Company's earnings performance and the incentives paid to executives.

     Stock Options. The Committee provides the Company's executive officers with
long-term incentive compensation through grants of stock options under the
Company's 1992 Stock Option Plan. The Committee believes that stock options
provide the Company's executive officers with the opportunity to purchase and
maintain an equity interest in the Company and to share in the appreciation of
the value of the Company's Common Stock. The Committee believes that stock
options directly motivate an executive to maximize long-term stockholder value.
The options also use vesting periods that encourage key executives to continue
in their employment with the Company. All options granted to executive officers
to date have been granted at the fair market value of the Company's Common Stock
on the date of grant. The Committee considers the grant of each option
subjectively, considering factors such as the executive officer's relative
position and responsibilities with the Company, the individual performance of
the executive officer over the previous fiscal year, and the anticipated
contribution of the executive officer to the attainment of the Company's long-
term strategic performance goals. Stock options granted in prior years are also
taken into consideration. The Committee views stock option grants as an
important component of its long-term, performance-based compensation philosophy.

     CEO Salary. The compensation of Mr. Berkeley, President and Chief Executive
Officer of the Company, consisted of base salary, an annual bonus and incentive
stock options. The Board of Directors periodically reviews the CEO's base salary
and bonus and revises his compensation based on the Board's overall evaluation
of his performance toward the achievement of the Company's financial, strategic
and other goals, with consideration given to his length of service and to
comparative chief executive officer compensation information. The Compensation
Committee believes that the Company's success is dependent in part upon the
efforts of its Chief Executive Officer. In fiscal 1998, Mr. Berkeley earned a
base salary of $276,000 as set by the Compensation Committee and earned a bonus
of $70,629 which was based on performance objectives.  Mr. Berkeley also
received an option to purchase 367,300 shares of Common Stock of the Company
(with an exercise price of 100% of market value of the Common Stock on the date
of grant).

     Option Repricing Report. In February 1998, all employees who held
outstanding options under the Company's stock options plans, including all
executive officers, were given the opportunity to reprice outstanding stock
options to the then current market price of $4.88 per share in return for
changing the vesting start date of the option to a point six months after the
original start date.  The Company took this action to retain key employees at a
time of intense competition for experienced personnel.  There were no separate
analyses of the impact of the repricing on the overall compensation of the
executive officers or any other employees.

     The following table provides the specified information concerning all
repricings of options to purchase the Company's Common stock held by any
executive officer of the Company since August 15, 1996, the date of the
Company's initial public offering:
