                          AGREEMENT AND PLAN OF MERGER



                  AGREEMENT AND PLAN OF MERGER,  dated as of July 8, 1997, among
CDSI HOLDING CORPORATION,  a Delaware corporation  ("Parent"),  CDSI ACQUISITION
CORP.,  a  Delaware   corporation  and  a  wholly-owned   subsidiary  of  Parent
("Acquisition"),  and CONTROL DATA SYSTEMS,  INC., a Delaware  corporation  (the
"Company"). The Company and Acquisition are hereinafter sometimes referred to as
the "Constituent Corporations" and the Company as the "Surviving Corporation."

                  WHEREAS  the   respective   Boards  of  Directors  of  Parent,
Acquisition  and the Company have each  approved,  upon the terms and subject to
the  conditions   hereinafter  provided,  the  acquisition  of  the  Company  by
Acquisition  pursuant to a tender offer by Acquisition  for all the  outstanding
shares of Common Stock, $.01 par value ("Company Common Stock"), of the Company,
followed by a merger of Acquisition with and into the Company;

                  NOW,    THEREFORE,    in    consideration    of   the   mutual
representations,  warranties,  covenants,  agreements and  conditions  contained
herein, and in order to set forth the terms and conditions of the Merger and the
mode of carrying  the same into  effect,  the  parties  hereto  hereby  agree as
follows:


                                    ARTICLE I

                                    THE OFFER

                  SECTION 1.01 The Offer.  (a) Provided  that nothing shall have
occurred that, had the Offer referred to below been  commenced,  would give rise
to a right to terminate the Offer under any of the conditions set forth in Annex
I hereto,  Acquisition  shall, as promptly as practicable after the date hereof,
but in no event later than five business days following the public  announcement
of the terms of this Agreement,  commence an offer (the "Offer") to purchase all
of the  outstanding  shares (the "Shares" of Company  Common Stock at a price of
$20.25  per  Share,  net to the  seller  in cash  (or at such  higher  price  as
Acquisition,  in its sole  discretion,  elects to  offer),  but  subject  to any
withholding  required by law. The Offer shall be subject to the  condition  that
there shall be validly  tendered prior to the  expiration  date of the Offer and
not  withdrawn  a number  of  Shares  representing  at least  51% of the  Shares
outstanding on a fully diluted basis (the "Minimum  Condition") and to the other
conditions set forth in Annex I hereto.  For purposes of determining the Minimum
Condition,  (i) Shares  tendered  subject to  guaranteed  delivery  shall not be
considered  validly tendered unless and until delivery shall have been completed
and (ii) Shares out-









standing on a  fully-diluted  basis shall mean all Shares  actually  outstanding
plus  all  Shares   issuable   upon   exercise,   conversion   or   exchange  of
then-outstanding  options,  warrants  and  other  rights to  purchase,  or other
securities convertible into or exchangeable for, Company Common Stock, including
any Shares  issuable  pursuant to the Company Stock Purchase Plan or the Company
Stock  Option  Plan (each as defined in  Section  3.05).  Acquisition  expressly
reserves the right to waive the Minimum Condition or any of the other conditions
to the Offer and to make any  change in the terms or  conditions  of the  Offer;
provided that no change may be made that changes the form of consideration to be
paid or  decreases  the price per  Share or the  number of Shares  sought in the
Offer or which imposes conditions to the Offer in addition to those set forth in
Annex I.

                  (b) As soon as practicable on the date of  commencement of the
Offer,  Acquisition  shall  file with the  Securities  and  Exchange  Commission
("SEC") a Tender  Offer  Statement  on Schedule  14D-1 with respect to the Offer
which will  contain  the offer to  purchase  and form of the  related  letter of
transmittal  (together with any supplements or amendments thereto,  collectively
the "Offer  Documents").  Acquisition  and the Company  each agrees  promptly to
correct any information  provided by it for use in the Offer Documents if and to
the  extent  that it shall  have  become  false or  misleading  in any  material
respect.  Acquisition  agrees  to take all  steps  necessary  to cause the Offer
Documents  as so corrected  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. The Company and its counsel shall be given a reasonable
opportunity  to review and comment on the Offer  Documents  prior to their being
filed with the SEC.

                  SECTION 1.02 Company  Action.  (a) The Company hereby consents
to the  Offer and  represents  that its Board of  Directors,  at a meeting  duly
called and held,  has (i)  unanimously  determined  that this  Agreement and the
transactions contemplated hereby, including the Offer and the Merger (as defined
in  Section  2.01),  are  fair  to and in the  best  interest  of the  Company's
stockholders,  (ii)  unanimously  approved this  Agreement and the  transactions
contemplated  hereby,  including  the  Offer  and  the  Merger,  which  approval
constituted approval of the Offer, the Merger and this Agreement for purposes of
Sections  203 and 251 of the  General  Corporation  Law of the State of Delaware
(the "Delaware GCL"), and (iii) unanimously  resolved to recommend acceptance of
the Offer and  approval  and  adoption of this  Agreement  and the Merger by its
stockholders.  The Company further represents that Cowen & Company has delivered
to the Company's  Board of Directors its written opinion that, as of the date of
such opinion,  the  consideration to be paid in the Offer and the Merger is fair
to the holders of Shares (other than Parent and its affiliates) from a financial
point of view.  The  Company  has been  advised  that all of its  directors  and
executive officers intend either to tender




                                        2





their  Shares  pursuant  to the  Offer or to vote in favor  of the  Merger.  The
Company  will  promptly  furnish  Acquisition  with a list of its  stockholders,
mailing labels and any available  listing or computer file  containing the names
and addresses of all record holders of Shares and lists of securities  positions
of Shares  held in stock  depositories,  in each case true and correct as of the
most recent  practicable  date, and will provide to Acquisition  such additional
information  (including,  without  limitation,  updated  lists of  stockholders,
mailing labels and lists of securities  positions) and such other  assistance as
Acquisition may reasonably request in connection with the Offer.

                  (b)      As soon as practicable on the day that the Offer
is commenced,  the Company will file with the SEC a  Solicitation/Recommendation
Statement on Schedule  14D-9 (the  "Schedule  14D- 9"),  which shall reflect the
recommendations  of the  Company's  Board of  Directors  referred to above.  The
Company and Acquisition each agree promptly to correct any information  provided
by it for use in the  Schedule  14D-9 if and to the  extent  that it shall  have
become false or misleading in any material  respect.  The Company agrees to take
all steps necessary to cause the Schedule 14D-9 as so corrected 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. Parent,  Acquisition and
their  counsel  shall be given an  opportunity  to  review  and  comment  on the
Schedule 14D-9 prior to its being filed with the SEC.

                  SECTION 1.03 Directors.  (a) Effective upon the acceptance for
payment by Acquisition  of, and deposit by  Acquisition  with the depositary for
the Offer of funds sufficient to make payment for, a majority of the outstanding
Shares  pursuant to the Offer,  Acquisition  shall be entitled to designate  the
number of directors, rounded up to the next whole number, on the Company's Board
of Directors that equals the product of (i) the total number of directors on the
Company's  Board of Directors  (giving  effect to the election of any additional
directors  pursuant to this Section) and (ii) the percentage  that the number of
Shares owned by Acquisition (including Shares accepted for payment and for which
deposit  has  been  made as  aforesaid)  bears to the  total  number  of  Shares
outstanding,   and  the  Company  shall  take  all  action  necessary  to  cause
Acquisition's  designees to be elected or appointed  to the  Company's  Board of
Directors, including, without limitation, increasing the number of directors and
seeking and accepting  resignations of incumbent  directors.  At such times, the
Company will use its best efforts to cause individuals designated by Acquisition
to constitute the same percentage as such individuals represent on the Company's
Board of Directors of (A) each  committee of the Board (other than any committee
of the Board established to take action under this Agreement), (B) each board of
directors of each Subsidiary (as defined in Section 3.02) and (C) each committee
of each such




                                        3





board.  Notwithstanding the foregoing,  at all times prior to the Effective Time
the Board shall  include at least two  directors in office as of the date hereof
who are not employees of the Company or any of its subsidiaries or affiliates of
Parent or Acquisition (any such director remaining in office being a "Continuing
Director").

                  (b) The  Company's  obligations  to appoint  designees  to the
Board of  Directors  shall be subject to Section  14(f) of the  Exchange Act (as
defined in Section  3.06) and Rule 14f-1  promulgated  thereunder.  The  Company
shall  promptly  take all actions  required  pursuant to Section  14(f) and Rule
14f-1 in order to fulfill its  obligations  under this Section and shall include
in the  Schedule  14D-9 such  information  with  respect to the  Company and its
officers and  directors  as is required  under  Section  14(f) and Rule 14f-1 to
fulfill its obligations under this Section 1.03.  Acquisition will supply to the
Company in writing and be solely responsible for any information with respect to
itself and its nominees,  officers, directors and affiliates required by Section
14(f) and Rule 14f-1.


                                   ARTICLE II

                                   THE MERGER

                  SECTION 2.01 The Merger. As promptly as reasonably practicable
after  consummation  of the Offer,  subject to the terms and  conditions of this
Agreement,  at the Effective Time (as hereinafter  defined),  in accordance with
this Agreement and the Delaware GCL,  Acquisition  shall be merged with and into
the Company (the "Merger"),  the separate existence of Acquisition (except as it
may be  continued  by  operation  of law) shall  cease,  and the  Company  shall
continue as the surviving corporation.

                  SECTION 2.02 Effect of the Merger.  Upon the  effectiveness of
the Merger, the Surviving Corporation shall succeed to and assume all the rights
and  obligations of the Company and  Acquisition in accordance with the Delaware
GCL and the Merger shall  otherwise have the effects set forth in Section 259 of
the Delaware GCL.

                  SECTION  2.03   Consummation   of  the  Merger.   As  soon  as
practicable   after  the  satisfaction  or  waiver  of  the  conditions  to  the
obligations of the parties to effect the Merger set forth herein,  provided that
this Agreement has not been terminated previously, the parties hereto will cause
the Merger to be  consummated by filing with the Secretary of State of the State
of Delaware a properly  executed  certificate  of merger in accordance  with the
Delaware GCL,  which shall be effective upon filing or on such later date as may
be  specified  therein  (the time of such  effectiveness  being  the  "Effective
Time").




                                        4






                  SECTION 2.04 Certificate of Incorporation;  By-Laws; Directors
and Officers.  The Certificate of  Incorporation of Acquisition in effect at the
Effective  Time  shall be the  Certificate  of  Incorporation  of the  Surviving
Corporation,  until thereafter amended in accordance with the provisions thereof
and as provided by the Delaware GCL. The By-Laws of Acquisition in effect at the
Effective  Time  shall  be the  By-Laws  of  the  Surviving  Corporation,  until
thereafter amended in accordance with the provisions thereof and the Certificate
of  Incorporation  of the Surviving  Corporation and as provided by the Delaware
GCL. From and after the Effective Time and until their respective successors are
duly elected or appointed and qualified, (a) the directors of Acquisition at the
Effective Time shall be the directors of the Surviving  Corporation  and (b) the
officers  of the  Company at the  Effective  Time shall be the  officers  of the
Surviving Corporation.

                  SECTION 2.05 Conversion of Securities. By virtue of the Merger
and  without  any action on the part of either  Constituent  Corporation  or any
holder of the capital stock thereof, at the Effective Time:

                           (a) Each share of Common  Stock,  $.01 par value,  of
         Acquisition  issued and outstanding  immediately prior to the Effective
         Time shall be converted into and become one validly issued,  fully paid
         and nonassessable share of Common Stock of the Surviving Corporation;

                           (b) Each share of Company  Common  Stock that is held
         in the  treasury  of the  Company or of any  Subsidiary,  or by Parent,
         Acquisition or any of their subsidiaries, shall be canceled and retired
         and no consideration  shall be paid or delivered in exchange  therefor;
         and

                           (c) Each  remaining  share of  Company  Common  Stock
         issued and outstanding  immediately  prior to the Effective Time (other
         than Dissenting  Shares, as defined in Section 2.08) shall be converted
         into the right to receive an amount in cash, without interest, equal to
         the  $20.25 or any  higher  price paid for each Share in the Offer (the
         "Merger Consideration").

                  SECTION  2.06  Stock  Options.  (a)  All  stock  options  out-
standing at the  Effective  Time under the Company Stock Option Plan (as defined
in Section  3.05)  shall,  whether or not  exercisable  or vested,  become fully
exercisable  and  vested,  and each  holder  of an  option  thereunder  shall be
entitled to receive from the Company,  as of the Effective  Time, for each share
of Company  Common Stock subject to an option an amount in cash in  cancellation
of such option equal to the excess, if any, of the Merger Consideration over the
per share exercise price of such option, subject to applicable  withholding,  if
any. The Company Stock Option Plan




                                        5





and all options issued and outstanding  thereunder shall terminate  effective as
of the Effective Time.

                  (b)  Immediately  prior to the  Effective  Time,  all  options
outstanding  under the Company Stock  Purchase Plan (as defined in Section 3.05)
shall become  exercisable  to the extent of payroll  deductions  accumulated  by
participants  as of such  date,  and each  participant  shall be  deemed to have
purchased  the  number  of whole  Shares  subject  to the  options  held by such
participant  at a per Share price  determined  pursuant to the provisions of the
Company Stock Purchase Plan, and each  participant  shall receive a cash payment
equal to the balance, if any, of such accumulated  payroll deductions  remaining
after the  deemed  purchase  of such  Shares.  As of the  Effective  Time,  each
participant  shall  receive,  for each Share such  participant is deemed to have
purchased,  the Merger  Consideration.  The Company Stock  Purchase Plan and all
options issued and outstanding  thereunder  shall terminate  effective as of the
Effective Time.

                  SECTION  2.07 Payment for Shares.  (a) Prior to the  Effective
Time,  Parent shall  designate a bank or trust company to act as exchange  agent
(the "Exchange Agent") for the purpose of exchanging  certificates  representing
Shares  for  the  Merger  Consideration.  At  the  Effective  Time,  Parent  and
Acquisition  shall cause such funds as are  required for the  conversion  of the
Shares pursuant to Section 2.05(c) hereof (the "Exchange  Fund") to be deposited
with the Exchange Agent.

                  (b)  Promptly   after  the  Effective   Time,   the  Surviving
Corporation  shall  instruct the Exchange Agent to mail to each holder of record
of one or more  shares of Company  Common  Stock,  (i) a letter of  transmittal,
which shall specify that delivery shall be effected,  and risk of loss and title
to the  certificates  that  immediately  prior to the Effective Time represented
outstanding Shares (each, a "Certificate") shall pass, only upon proper delivery
of the  Certificate  to the  Exchange  Agent and have such other  provisions  as
Parent shall specify,  and (ii)  instructions for use in effecting the surrender
of the Certificates in exchange for Merger  Consideration.  Until surrendered as
contemplated by this Section 2.07, each Certificate  shall be deemed at any time
after the  Effective  Time to  represent  only the right to  receive  the Merger
Consideration. No interest will be paid or accrued on the Merger Consideration.

                  (c) Upon surrender of a Certificate  for  cancellation  to the
Exchange  Agent,  together  with such letter of  transmittal,  duly executed and
completed in accordance with the instructions  thereto, and such other documents
as may  reasonably  be  required  by the  Exchange  Agent,  the  holder  of such
Certificate  shall be  entitled  to  receive  in  exchange  therefor  the Merger
Consideration  payable in respect of the Shares  previously  represented by such
Certificate, after giving effect to any applicable withholding




                                        6





tax, and the Certificate so surrendered shall forthwith be canceled.

                  (d) If Merger  Consideration is to be paid to any person other
than the  person in whose  name the  Certificates  for  Shares  surrendered  for
conversion  are  registered,  it shall be a condition  of the payment  that such
Certificates be properly endorsed and the signatures thereon properly guaranteed
and  otherwise in proper form for transfer and that the person  requesting  such
payment shall pay to the Exchange  Agent any transfer or other taxes required by
reason  of the  delivery  of Merger  Consideration  to a person  other  than the
registered holder of such Certificate, or shall establish to the satisfaction of
the Exchange Agent that such tax has been paid or is not applicable.

                  (e) Any  portion  of the  Exchange  Fund held by the  Exchange
Agent for delivery pursuant to this Section 2.07 and unclaimed at the end of six
months after the Effective Time shall be repaid or  redelivered to Parent,  upon
demand,  and any holders of Certificates who have not theretofore  complied with
this Section 2.07 shall,  subject to applicable law, thereafter look only to the
Surviving Corporation for payment of the Merger Consideration in respect of such
holders' Shares.  Notwithstanding  the foregoing,  none of Parent, the Surviving
Corporation  or the  Exchange  Agent  shall be liable to any holder of Shares of
Company  Stock  for  any  amount  paid  to a  public  official  pursuant  to any
applicable abandoned property,  escheat or similar law. Any amounts unclaimed by
holders of Shares  two years  after the  Effective  Time (or such  earlier  date
immediately  prior to such time as such amounts  would  otherwise  escheat to or
become the property of any  governmental  entity) shall, to the extent permitted
by applicable  law,  become the property of the Surviving  Corporation  free and
clear of any claims or interest of any person previously entitled thereto.

                  (f) The  Exchange  Agent shall invest any cash in the Exchange
Fund, as directed by Parent,  in (i) direct  obligations of the United 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 or (iii) commercial paper rated, at the time of purchase,  in either of
the two highest quality  categories by both Moody's Investors  Services Inc. and
Standard & Poor's Ratings Group,  a division of  McGraw-Hill,  Inc., and any net
earnings with respect  thereto shall be paid to Parent as and when  requested by
Parent.  In the  event  the  Exchange  Fund  shall  realize  a loss on any  such
investment,  Parent shall promptly  thereafter deposit in the Exchange Fund cash
in an amount  sufficient  to enable the Exchange  Fund to satisfy all  remaining
obligations originally contemplated to be paid out of the Exchange Fund.





                                        7





                  (g) At and after the Effective  Time, the stock transfer books
of the Company shall be closed,  and there shall be no further  registrations of
transfers  of shares of Company  Common Stock  thereafter  on the records of the
Company.  If,  after the  Effective  Time,  Certificates  are  presented  to the
Surviving  Corporation,  Parent or the Exchange Agent for any reason, they shall
be canceled and exchanged for Merger  Consideration  as provided in this Section
2.07.

                  SECTION 2.08 Dissenting  Shares.  Notwithstanding  anything in
this Agreement to the contrary, Shares that are outstanding immediately prior to
the  Effective  Time and that are held by  stockholders  who have not voted such
Shares in favor of the  approval and  adoption of this  Agreement  and who shall
have  delivered  a written  demand for  appraisal  of such  shares in the manner
provided in Section 262 of the Delaware GCL  ("Dissenting  Shares") shall not be
converted into the right to receive the Merger Consideration, but the holders of
such Shares shall be entitled to payment of the  appraised  value of such Shares
in accordance with the provisions of Section 262 of the Delaware GCL;  provided,
however,  that (i) if any holder of Dissenting Shares shall subsequently deliver
a written  withdrawal of such holder's demand for appraisal of such shares (with
the written  approval of the Surviving  Corporation,  if such  withdrawal is not
tendered  within 60 days after the Effective  Time), or (ii) if any holder fails
to perfect or loses such holder's appraisal rights as provided in Section 262 of
the Delaware  GCL, or (iii) if any holder of  Dissenting  Shares fails to demand
payment within the time period provided in Section 262 of the Delaware GCL, such
holder shall forfeit the right to appraisal of such shares and such shares shall
thereupon be deemed to have been converted  into, as of the Effective  Time, the
right to receive the Merger  Consideration,  without any interest  thereon.  The
Company  shall give  Acquisition  prompt  notice of any demands  received by the
Company for  appraisal  of Shares,  and the Company  shall not,  except with the
written consent of  Acquisition,  make any payment with respect to, or settle or
offer to settle, any such demands.

                  SECTION 2.09  Dissenting  Shares After  Payment of Fair Value.
Dissenting  Shares,  if any,  shall be canceled  after payments of fair value in
respect  thereto  have  been  made to  dissenting  stockholders  of the  Company
pursuant to the Delaware GCL.

hereinafter  defined) on the Company. As used herein,  "Material Adverse Effect"
shall  mean,  with  respect  to any  party,  a  material  adverse  effect on the
business,  assets,  condition  (financial or other) or operating results of such

business as it is now being  conducted.  Each  Subsidiary is duly qualified as a
foreign  corporation  to  do  business,   and  is  in  good  standing,  in  each
jurisdiction  in which the  character of its  properties  owned or leased or the
nature of its activities makes such  qualification  necessary,  except where the
failure to be so qualified  would not  reasonably be expected to have a Material
Adverse Effect on the Company. Each Subsidiary and its jurisdiction of formation

transactions  contemplated  hereby have been duly  authorized  by the  Company's
Board  of  Directors,  and no  other  corporate  proceedings  on the part of the
Company  are  necessary  to  authorize  this  Agreement  and  the   transactions
contemplated hereby, other than the approval and adoption of this Agreement by a
majority  of the  stockholders  of the  Company.  This  Agreement  has been duly
executed and delivered by the Company and, subject to such stockholder approval,
constitutes the legal, valid and binding obligation of the Company,  enforceable
against the Company in accordance with its terms.

any lien,  charge or encumbrance of any nature  whatsoever upon any asset of the
Company or any  Subsidiary;  other than (in the cases of clauses  (ii) and (iii)

the Company consists of (i) 50,000,000  shares of Company Common Stock, and (ii)
5,000,000 shares of preferred stock, $.01 par value ("Preferred  Stock").  As of

purchase,  redeem or  otherwise  acquire any shares of its capital  stock or any
interest  therein  or to pay any  dividend  or make any  other  distribution  in
respect thereof.

                  SECTION 3.06 SEC  Filings.  The Company has provided to Parent

Company on Form 10-K for the years ended December 31, 1994,  1995 and 1996, (ii)

individually and in the aggregate,  could not materially impair the use or value
of the assets subject  thereto),  (vi) sold,  assigned or transferred any of its
tangible assets, or canceled any debts or claims,  except in the ordinary course

to  stockholders  for the year  ended  December  31,  1996  (each,  a  "Business
Segment").

                  SECTION 3.09  Governmental  Approvals.  No consent,  approval,
order or authorization of, or registration, declaration

authority is required to be made or obtained by the Company in  connection  with
the execution and delivery of this Agreement by the Company or the  consummation

registrations,  declarations or filings which if not made,  would not materially
adversely  affect the  ability of the  Company to  consummate  the  transactions
contemplated hereby or the ability of the Surviving  Corporation or any Business
Segment to conduct  its  business  after the  Effective  Time  substantially  as
currently conducted by the Company or such Business Segment.

                  SECTION  3.10  Compliance  with  Laws.  Except as set forth in
Section 3.10 of the Disclosure Schedule,  neither the Company nor any Subsidiary
is in default  under or in  violation  of any order of any  court,  governmental
authority  or  arbitration  board or  tribunal  to  which  the  Company  or such
Subsidiary  is  or  was  subject  or  in  violation  of  any  laws,  ordinances,
governmental rules or regulations (including, but not limited to, those relating
to export controls,  labor and employment matters and foreign corrupt practices)
to which the  Company  or any  Subsidiary  is or was  subject,  except  for such
defaults or violations that, in the aggregate,  would not reasonably be expected
to have a Material  Adverse  Effect.  Except as set forth in said Section  3.10,
neither  the  Company  nor any  Subsidiary  has failed to obtain  any  licenses,
permits,  franchises  or  other  governmental  authorizations  necessary  to the
ownership of its  properties  or to the conduct of its  business,  which failure
would  reasonably  be expected to have a Material  Adverse  Effect,  and,  after
giving  effect  to the  transactions  contemplated  hereby,  all such  licenses,
permits,  franchises and other governmental  authorizations  will continue to be
valid and in full  force and  effect,  except  where  the  failure  to have such
licenses,  permits,  franchises and other governmental  authorizations would not
reasonably be expected to have a Material Adverse Effect on the Company.

                  SECTION 3.11 Disclosure Documents.  (a) Each document required
to be filed by the  Company  with the SEC in  connection  with the  transactions
contemplated  hereby   (collectively,   the  "Company  Disclosure   Documents"),

                                       13

requirements of the Exchange Act.

                  (b) The Proxy  Statement  (as defined in Section  6.02 hereof)
will not (i) at the time it or any  amendment or  supplement  is first mailed to
stockholders of the Company,  at the time such  stockholders vote on adoption of
this  Agreement and at the  Effective  Time,  contain any untrue  statement of a
material  fact or  omit  to  state  any  material  fact  necessary  to make  the
statements  therein,  in light of the circumstances  under which they were made,
not misleading or (ii) at the time of such  stockholder vote or at the Effective
Time,  omit any  information  necessary to correct any statement that has become
materially false or misleading in any earlier  communication with respect to the
solicitation  of any proxy for such  meeting.  At the time of the  filing of any
Company  Disclosure  Document other than the Proxy  Statement and at the time of
distribution  thereof,  such Company  Disclosure  Document  will not contain any
untrue statement of a material fact or omit to state any material fact necessary
to make the statements  therein,  in light of the circumstances under which they
were made, not misleading.  Notwithstanding the foregoing,  no representation is
made  by  the  Company  with  respect  to  information  supplied  by  Parent  or
Acquisition  specifically  for  inclusion  in the Proxy  Statement  or any other
Company Disclosure Document that relates to Parent or any affiliate or associate
of Parent.

                  (c)  The  information  with  respect  to  the  Company  or any
Subsidiary that the Company furnishes to Parent in writing  specifically for use
in the Offer Documents,  or that is incorporated  therein by reference to any of
the  Company  SEC  Filings,  will  not,  at the time of the  filing of the Offer
Documents,  at the  time  of any  distribution  thereof  and at the  time of the
consummation  of the Offer,  contain any untrue  statement of a material fact or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading.

                  SECTION 3.12  Litigation.  Except as set forth in Section 3.12
of the Disclosure Schedule, there is no action, suit, investigation,  proceeding
or claim  pending or, to the  knowledge  of the Company,  threatened  against or
affecting  the Company or any  Subsidiary,  or their  respective  properties  or
rights,  before any governmental body or arbitration  board or tribunal,  either
alone or  together  with other  similar  actions,  the  outcome  of which  would
reasonably be expected to have a Material Adverse Effect on the Company.

                  SECTION  3.13  Software.  (a)  Except as set forth in  Section
3.13(a) of the Disclosure Schedule, the Company and each of the Subsidiaries has
valid licenses to all copies of all software that is not owned by it and is used

and




                                       14





the  use by the  Company  or  such  Subsidiary  of such  Third  Party  Software,
including without limitation all modifications and enhancements thereto (whether
or not created by the  Company),  complies  with such  license  (except for such
noncompliance  as could not,  individually  or in the  aggregate,  be reasonably
expected to have a Material Adverse Effect on the Company).  Except as set forth
in Section 3.13(a) of the Disclosure Schedule, the Company owns all right, title
and interest in and to all software  marketed or licensed by the Company and the
Subsidiaries  to customers or held for use or in  development  for marketing and
licensing to customers (collectively, the "Proprietary Software").

                  (b) Except as set forth in Section  3.13(b) of the  Disclosure
Schedule,  to the  Company's  knowledge,  none of the Third  Party  Software  or
Proprietary  Software,  no use thereof by the Company or any Subsidiary,  and no
permitted  use thereof by any  licensee  infringes  upon or violates any patent,
copyright,  trade secret or other  intellectual  property right of any person or
entity.  No claim or demand with respect to any such  infringement  or violation
has been made or, to the knowledge of the Company, threatened.

                  (c) To the  knowledge of the Company,  there are no viruses in
the Proprietary  Software and there are no defects in the  Proprietary  Software
that would prevent such software  from  performing in all material  respects the
tasks and  functions  that it was  intended to perform  except those that can be
cured without a Material Adverse Effect on the Company.

                  SECTION  3.14 Trade  Secrets.  No third  party has  claimed or
notified the Company or any Subsidiary  that any person employed by or otherwise
affiliated  with the  Company or any  Subsidiary  has,  in respect of his or her
activities  to  date,  violated  any of the  terms or  conditions  of his or her
employment  contract  with any third  party,  or disclosed or utilized any trade
secrets or  proprietary  information  or  documentation  of any third party,  or
interfered in the employment relationship between any third party and any of its
employees,  and to the  knowledge  of the  Company,  no  person  employed  by or
otherwise  affiliated  with the Company or any Subsidiary has employed any trade
secrets or any information or documentation  proprietary to any former employer,
or violated any  confidential  relationship  which such person may have had with
any third party,  in connection  with the development or sale of any products of
the Company or any Subsidiary.

                  SECTION 3.15  Severance  Arrangements.  Except as set forth in
Section 3.15 of the Disclosure Schedule,  neither the Company nor any Subsidiary
is  party  to any  agreement  with  any  employee  (i)  the  benefits  of  which
(including, without limitation, severance benefits) are contingent, or the terms
of which are materially altered, upon the occurrence of a transaction




                                       15





involving the Company or any Subsidiary of the nature of any of the transactions
contemplated by this Agreement or (ii) providing severance benefits in excess of
those generally available under the Company's severance policies as in effect on
the  date  hereof  (which  are  described  in  Section  3.15  of the  Disclosure
Schedule),  or  which  are  conditioned  upon a change  of  control,  after  the
termination  of employment of such  employees  regardless of the reason for such
termination of employment. Except as set forth in Section 3.15 of the Disclosure
Schedule,  neither the Company nor any  Subsidiary is a party to any  employment
agreement or compensation  guarantee extending for a period longer than one year
from the date hereof.

                  SECTION 3.16 Taxes. (a) Except as set forth in Section 3.16 of
the  Disclosure  Schedule,  each  of  the  Company,  the  Subsidiaries  and  any

assets,  operations,  activities and status of the Company and the Subsidiaries,
(ii) timely paid or withheld  all Taxes that are due and payable with respect to
the Returns referred to in clause (i) (other than Taxes that are being contested
in good faith by appropriate  proceedings and are adequately reserved for in the
Company's most recent  consolidated  financial  statements  described in Section
3.07 hereof),  (iii)  established  reserves that are adequate for the payment of
all Taxes not yet due and payable with respect to the results of  operations  of
the  Company  and the  Subsidiaries  through  the date  hereof,  and (iv) to the
knowledge of the Company,  complied in all material respects with all applicable
laws, rules and regulations relating to the payment and withholding of Taxes and

outstanding Shares (on a fully diluted basis), the Company shall take all action
necessary  in  accordance   with  the  Delaware  GCL  and  its   Certificate  of
Incorporation  and  By-Laws  to call,  give  notice of and  convene a meeting (a
"Meeting")  of its  stockholders  to  consider  and vote upon the  approval  and
adoption of this  Agreement and the Merger and for such other purposes as may be
necessary or  desirable.  The Board of  Directors of the Company has  determined
that the Merger is advisable and in the best  interests of the  stockholders  of
the  Company  and shall,  subject  to  fiduciary  duties as advised by  counsel,
recommend  that the  stockholders  of the Company vote to approve and adopt this
Agreement and the Merger and any other  matters to be submitted to  stockholders
in connection therewith.

                  (b)  As  promptly  as  reasonably  practicable  following  the
acquisition by Acquisition of a majority of the  outstanding  Shares (on a fully
diluted  basis),  the  Company  shall  file a  proxy  or  information  statement
pertaining to the Merger (the "Proxy  Statement").  Parent and Acquisition shall
cooperate  fully with the Company in the  preparation of the Proxy Statement and
any  amendments  and  supplements  thereto.  The  Proxy  Statement  shall not be
distributed,  and no  amendment  or  supplement  thereto  shall  be  made by the
Company,  without the prior consent of Parent and its counsel. The Company shall
use its best  efforts to have the Proxy  Statement  cleared by the SEC and shall
cause  a  definitive  Proxy  Statement  to be  distributed  to its  stockholders
entitled to vote upon the Merger as promptly as practicable thereafter.

                  (c) The  Company  shall  notify  Parent of the  receipt of the
comments of the SEC and of any requests by the SEC for amendments or supplements
to the Proxy Statement or for additional information,  and shall promptly supply
Parent  with  copies  of  all   correspondence   between  the  Company  (or  its
representatives)




                                       25





and the SEC (or its staff) with  respect  thereto.  If, at any time prior to the
Meeting, any event should occur relating to or affecting the Company,  Parent or
Acquisition, or to their respective officers or directors, which event should be
described in an  amendment or  supplement  to the Proxy  Statement,  the parties
shall  promptly  inform one another and shall  cooperate in promptly  preparing,
filing and clearing with the SEC and, if required by applicable securities laws,
distributing to the Company's stockholders such amendment or supplement.

                  SECTION 6.03 Access to Information. (a) The Company shall, and
shall cause the Subsidiaries and its and their respective  officers,  directors,
employees,  representatives  and agents to, afford,  from the date hereof to the
Effective Time, the officers,  employees,  representatives  and agents of Parent
reasonable  access during  regular  business  hours to its officers,  employees,
agents,  properties,  books, records and workpapers,  and shall promptly furnish
Parent  all  financial,  operating  and other  information  and data as  Parent,
through its officers, employees or agents, may reasonably request.

                  (b) Except as required  by law,  Parent  shall hold,  and will
cause its respective  officers,  employees,  representatives and agents to hold,
any confidential  information in accordance with the  Confidentiality  Agreement
dated November 1, 1995 between the Company and Welsh,  Carson,  Anderson & Stowe
VII, L.P. (the "Confidentiality Agreement").

                  (c) No  investigation  pursuant  to this  Section  6.03  shall
affect, add to or subtract from any representations or warranties of the parties
hereto or the conditions to the  obligations of the parties hereto to consummate
the Offer or effect the Merger.

                  SECTION  6.04  Further  Assurances.  Subject  to the terms and
conditions  herein  provided,  each  of the  parties  hereto  agrees  to use all
reasonable efforts to take, or cause to be taken, all action and to do, or cause
to be done,  all things  necessary,  proper or advisable to consummate  and make
effective  as promptly as  practicable  the  transactions  contemplated  by this
Agreement, including, without limitation, using all reasonable efforts to obtain
all  necessary  waivers,  consents  and  approvals  and to effect all  necessary
registrations and filings  (including  without  limitation any necessary filings
under the HSR Act);  provided that the foregoing shall not require Parent or the
Company to make,  or agree to make,  or require  Parent to permit the Company or
any the Subsidiaries to make, any divestiture of a significant asset in order to
obtain any waiver, consent or approval.

                  SECTION 6.05 Inquiries and Negotiations; Certain Payments. (a)
From the date hereof until the termination hereof, the Company, the Subsidiaries
and their respective




                                       26





officers,  directors,  employees,  representatives  and other  agents  will not,
directly or  indirectly,  solicit or initiate any  discussions,  submissions  of
proposals or offers or negotiations  with or, subject to the fiduciary duties of
the  Company's  Board of  Directors  as advised by counsel,  participate  in any
negotiations  or  discussions  with, or provide any  information  or data of any
nature whatsoever to, or otherwise cooperate in any other way with, or assist or
participate  in,  facilitate  or encourage any effort or attempt by, any person,
corporation, entity or "group" (as defined in Section 13(d) of the Exchange Act)
other than Parent and its affiliates, representatives and agents (each, a "Third
Party") in connection with any merger, consolidation,  sale of any Subsidiary or
division  that is material to the business of the Company and the  Subsidiaries,
sale of shares of capital stock or other equity  securities,  tender or exchange
offer, recapitalization, debt restructuring or similar transaction involving the
Company  (such  transactions  being  hereinafter  referred  to  as  "Alternative
Transactions"),  provided,  however,  that nothing  contained in this  Agreement
shall prohibit the Company Board from taking and disclosing a position  required
by Rule 14e-2 under the  Exchange  Act.  The Company  shall  immediately  notify
Parent if any  proposal,  offer,  inquiry or other  contact is received  by, any
information is requested from, or any discussions or negotiations  are sought to
be  initiated  or  continued  with,  the  Company in  respect of an  Alternative
Transaction,  and shall, in any such notice to Parent,  indicate the identity of
the Third Party and the terms and  conditions  of any proposals or offers or the
nature of any inquiries or contacts,  and thereafter shall keep Parent informed,
on a current basis,  of the status and terms of any such proposals or offers and
the  status  of any such  discussions  or  negotiations.  Without  limiting  the
generality of the foregoing, the Company shall provide Parent with not less then
(i) two  business  days'  notice  prior to the  execution  by the Company of any
definitive  agreement with respect to any  Alternative  Transaction and (ii) two
days'  notice (or the  longest  notice  legally  permissible  in the  reasonable
determination  of counsel for the Company,  if less than two days) of any public
announcement  relating to any Alternative  Transaction.  Prior to furnishing any
non-public  information to, or entering into  negotiations or discussions  with,
any Third Party, the Company will obtain an executed  confidentiality  agreement
from such Third Party on terms  substantially  the same as, or no less favorable
to  the  Company  in  any  material   respect  than,   those  contained  in  the
Confidentiality  Agreement.  The Company shall not release any Third Party from,
or waive any  provision  of,  any such  confidentiality  agreement  or any other
confidentiality  or standstill  agreement to which the Company is a party. As of
the date hereof,  the Company shall cease,  and shall cause its subsidiaries and
the  officers,  directors,  employees,  representatives  and other agents of the
Company  and  its  subsidiaries  to  cease  all  discussions,  negotiations  and
communications with all Third Parties and demand the immediate




                                       27





return of all confidential information previously provided to Third Parties.

                  (b) If a Payment Event (as hereinafter  defined)  occurs,  the
Company  shall pay to Parent,  within two business days  following  such Payment
Event,  (i) a fee of $8,200,000 in cash, plus (ii) all reasonable and documented
out-of-pocket  costs and expenses of Parent and Acquisition,  including  without
limitation  fees and expenses of counsel,  accountants,  investment  bankers and
other advisors and printing expenses.  In the event that this Agreement shall be
terminated for any other reason and the Company shall have failed to comply with
or  perform,  or  shall  have  breached,  in any  material  respect,  any of its
covenants  or  agreements  contained  herein,  the Company  shall pay to Parent,
within two  business  days  following  such  termination,  the fees and expenses
referred to in clause (ii) of the  preceding  sentence;  provided that such fees
and expenses shall not be so payable if Parent or Acquisition  shall have failed
to comply with or perform, or shall have breached,  in any material respect, any
of its covenants or agreements contained herein.

                  (c)  "Payment   Event"  means  (i)  the  termination  of  this
Agreement by Parent  pursuant to Section  8.01(e);  (ii) the termination of this
Agreement by the Company  pursuant to Section 8.01(d) or (iii) the occurrence of
any of the  following  events within 6 months after the date of  termination  of
this  Agreement  (other than by reason of Parent's or  Acquisition's  failure to
comply  with or  perform,  or breach,  in any  material  respect,  of any of its
covenants or agreements  contained  herein) whereby  stockholders of the Company
receive,  pursuant to such event, cash, securities or other consideration having
an aggregate value,  when taken together with the value of any securities of the
Company or its  subsidiaries  otherwise held by the  stockholders of the Company
after such event, in excess of $20.90 per Share:  (w) the Company is acquired by
merger or otherwise by a Third Party;  (x) a Third Party  acquires more than 50%
of the total assets of the Company and the Subsidiaries, taken as a whole; (y) a
Third Party acquires more than 50% of the outstanding  Shares or (z) the Company
adopts and implements a plan of liquidation or share repurchase relating to more
than 50% of the outstanding Shares or an extraordinary dividend relating to more
than 50% of the assets of the Company and the Subsidiaries, taken as a whole.

                  (d) The Company  acknowledges that the agreements contained in
this Section 6.05 are an integral part of the transactions  contemplated by this
Agreement, and that, without these agreements,  Parent and Acquisition would not
enter into this Agreement; accordingly, if the Company fails to promptly pay any
amount due pursuant to this Section 6.05,  and, in order to obtain such payment,
Parent and/or  Acquisition  commences a suit which results in a judgment against
the Company for the fee and




                                       28





expenses set forth in this Section  6.05,  the Company  shall also pay to Parent
and  Acquisition  their  costs and  expenses  incurred in  connection  with such
litigation.  Notwithstanding the foregoing,  each party shall bear its own costs
and expenses incurred in connection with any litigation over the  reasonableness
and/or documentation of any expenses submitted for reimbursement hereunder.

                  (e) This Section 6.05 shall  survive any  termination  of this
Agreement, however caused.

                  SECTION  6.06  Notification  of Certain  Matters.  The Company
shall give prompt notice to Parent and  Acquisition,  and Parent and Acquisition
shall give prompt notice to the Company,  of (i) the  occurrence,  or failure to
occur, of any event that such party believes would be likely to cause any of its
representations  or  warranties  contained  in this  Agreement  to be  untrue or
inaccurate  in any  material  respect  at any time  from the date  hereof to the
Effective  Time  and  (ii)  any  material  failure  of the  Company,  Parent  or
Acquisition,  as the case may be, or any  officer,  director,  employee or agent
thereof,  to comply with or satisfy any  covenant,  condition or agreement to be
complied with or satisfied by it hereunder;  provided,  however, that failure to
give such  notice  shall not  constitute  a waiver  of any  defense  that may be
validly asserted.

                  SECTION  6.07   Indemnification.   (a)  The   Certificate   of
Incorporation  and  By-Laws  of the  Surviving  Corporation  shall  contain  the
provisions with respect to  indemnification  and exculpation  from liability set
forth in the Company's  Certificate of Incorporation and By-Laws as in effect on
the date hereof,  which provisions  shall not be amended,  repealed or otherwise
modified  for a period of six years from the  Effective  Time in any manner that
would adversely affect the rights  thereunder of individuals who, on or prior to
the Effective Time, were directors, officers, employees or agents of the Company
(collectively,  the "Indemnified Parties"), unless such modification is required
by law. Parent shall guarantee the obligations of the Surviving Corporation with
respect to indemnification of the Indemnified  Parties under such provisions and
under the Company's indemnification agreements with its directors and officers.

                  (b) For a period of two years after the expiration date of the
Company's current policy, the Surviving Corporation shall maintain officers' and
directors'  liability  insurance  covering  those  Indemnified  Parties  who are
currently covered by the Company's  directors' and officers' liability insurance
policy,  a copy of which has heretofore  been  delivered to Parent,  on terms no
less  favorable  than the terms of such current  insurance  coverage,  provided,
however,  that in no event shall the Surviving Corporation be required to expend
in any one year an amount in excess  of 150% of the  annual  premiums  currently
payable




                                       29





by the Company  for such  insurance,  provided,  further,  however,  that if the
annual  premiums of such insurance  coverage  exceed such amount,  the Surviving
Corporation  shall obtain a policy with the greatest  coverage  available  for a
cost not exceeding such amount.

                  (c) This Section 6.07 shall  survive the  consummation  of the
Merger at the Effective  Time, is intended to benefit the Company,  Parent,  the
Surviving  Corporation and the Indemnified  Parties, and shall be binding on the
successors and assigns of
the Surviving Corporation.

                  SECTION 6.08 Voting of Shares.  Each of Parent and Acquisition
agrees to vote all Shares  beneficially owned by it in favor of adoption of this
Agreement and approval of the Merger.

         enacted by any  governmental,  regulatory or  administrative  agency or
         authority  shall  be  in  effect  that  would  restrain  the  effective
         operation of the business of the Company and the Subsidiaries  from and
         after the Effective Time, and no proceeding  challenging this Agreement
         or the transactions  contemplated hereby or seeking to prohibit, alter,
         prevent  or  materially  delay the Merger  shall be pending  before any
         court, arbitrator or governmental agency, body or official; and

               or  enacted by any  governmental,  regulatory  or  administrative

               consummation of the Merger as contemplated hereby.

                  (b) by either  Parent or the  Company,  if (i) the Offer shall
not have been  consummated  on or prior to the close of  business on October 31,
1997; (ii) the conditions to its obligations under Section 7.01 or Section 7.02,
as the case may be,  shall  not have  been  complied  with or  performed  in any
material respect and such  noncompliance or  nonperformance  shall not have been
cured or  eliminated  (or by its nature  cannot be cured or  eliminated)  by the
other party on or before  December 31, 1997;  or (iii) the Merger shall not have
been effected on or prior to the close of business on December 31, 1997; unless,
in any case,  such event has been caused by the breach of this  Agreement by the
party seeking such termination;

                  (c) by Parent,  if the Offer is terminated or expires  without
the purchase of any Shares thereunder, unless such termination or expiration has

more favorable to the Company's stockholders than the transactions  contemplated
by this Agreement;  provided, that all amounts payable under Section 6.05 hereof
shall have been paid prior to such  termination  (except  for any amounts due in
respect of expenses for which  documentation  shall not have been provided prior
to such  termination,  which  amounts  shall be paid as promptly as  practicable
after delivery to the Company of required documentation thereof); or

                  (e) by Parent,  if (i) the Board of  Directors  of the Company
shall have  withdrawn,  modified  or  amended in a manner  adverse to Parent and
Acquisition  its  approval  or  recommendation  of the Offer  and the  Merger or
approved, recommended or endorsed any proposal for, or authorized the Company to
enter  into,  an  Alternative  Transaction,  or (ii) Cowen & Company  shall have
withdrawn  its  opinion at any time prior to the earlier of (A)  acceptance  for
payment of Shares by Acquisition under the Offer and (B) the Effective Time.

None  of  the  representations  and  warranties  in  this  Agreement  or in  any

                  SECTION  9.02  Expenses,  Etc.  (a)  In  the  event  that  the
transactions contemplated by this Agreement are not consummated, then, except as
set forth in Section 6.05(b),  neither the Company,  on the one hand, nor Parent
and Acquisition,  on the other hand, shall have any obligation to pay any of the
fees and  expenses of the other  incident to the  negotiation,  preparation  and
execution  of this  Agreement,  including  the fees  and  expenses  of  counsel,
accountants, investment bankers and other experts.

                  (b) In the event that the  transactions  contemplated  by this

which  event  such  party  shall  consult  with the other  prior to making  such
disclosure).

                  SECTION 9.04 Execution in Counterparts. For the convenience of
the parties, this Agreement may be executed in one or more counterparts, each of

notice in writing to the other parties hereto.

                  SECTION 9.06 Waivers. The Company, on the one hand, and Parent
and  Acquisition,  on the other hand,  may, by written notice to the other,  (i)
extend the time for the  performance of any of the  obligations or other actions
of  the  other  under  this  Agreement;  (ii)  waive  any  inaccuracies  in  the
representations or warranties of the other contained in this Agreement or in any
document delivered  pursuant to this Agreement;  (iii) waive compliance with any
of the  conditions  of the other  contained  in this  Agreement;  or (iv)  waive
performance of any of the obligations of the other under this Agreement.  Except
as  provided  in the  preceding  sentence,  no  action  taken  pursuant  to this
Agreement,  including,  without limitation, any investigation by or on behalf of
any  party,  shall be deemed to  constitute  a waiver by the party  taking  such
action  of  compliance  with  any  representations,   warranties,  covenants  or
agreements  contained  in this  Agreement.  The waiver by any party  hereto of a
breach of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent breach.

                  SECTION 9.07 Entire Agreement.  This Agreement, the Disclosure
Schedule,  the documents  executed at the Effective Time in connection  herewith
and the  Confidentiality  Agreement  constitute the entire  agreement  among the
parties hereto with respect to the subject matter hereof and supersede all prior
agreements and understandings, oral and written, among the parties hereto




                                       34





with respect to the subject  matter  hereof.  The Company may, in its discretion
and for its convenience,  include in the Disclosure  Schedule items that are not
material,  and  such  inclusions  shall  not be  deemed  to be an  agreement  or
admission  by the Company  that such items are  material or otherwise be used to
interpret the meaning of such term for purposes of this  Agreement or otherwise.
The parties  agree that no  representation,  warranty,  promise,  inducement  or
statement of intention  made by any party that is not embodied in this Agreement
or such other  documents  may be relied upon for any  purpose by any party,  and
none  of  the  parties  shall  be  bound  by,  or be  liable  for,  any  alleged
representation,  warranty,  promise,  inducement  or statement of intention  not
embodied herein or therein. The projections and budgets furnished by the Company
to  Parent  are  arithmetically  accurate,  based on the  assumptions  set forth
therein; it being understood that, while facts and circumstances  resulting in a
Material  Adverse  Effect on the Company may also result or be  reflected in the
Company's  failure to achieve such projected or budgeted  results,  such failure
shall not, in and of itself,  be deemed to be a Material  Adverse  Effect on the
Company.

                  SECTION 9.08  Applicable Law. This Agreement shall be governed
by and construed in accordance  with the laws of the State of Delaware,  without
regard to principles of conflict of laws.

                  SECTION 9.09 Binding  Effect,  Benefits.  This Agreement shall
inure to the  benefit  of and be  binding  upon the  parties  hereto  and  their
respective permitted successors and assigns.  Notwithstanding anything contained
in this  Agreement  to the  contrary,  nothing in this  Agreement,  expressed or
implied,  is intended to confer on any person  other than the parties  hereto or
their  respective  permitted  successors  and  assigns,  any  rights,  remedies,
obligations  or  liabilities  under or by  reason of this  Agreement;  provided,
however,  that the provisions of Section 6.07 hereof shall accrue to the benefit
of, and shall be  enforceable  by, each of the current and former  directors and
officers of the Company.

                  SECTION 9.10 Assignability.  Neither this Agreement nor any of
the parties'  rights  hereunder  shall be assignable by any party hereto without
the prior written consent of the other parties hereto.

                  SECTION 9.11 Amendments. This Agreement may be varied, amended
or  supplemented  at any time before or after the  approval and adoption of this
Agreement by the stockholders of the Company by action of the respective  Boards
of Directors  of the  Company,  Parent and  Acquisition,  without  action by the
stockholders  thereof;  provided  that,  after  approval  and  adoption  of this
Agreement  by  the  Company's  stockholders,  no  such  variance,  amendment  or
supplement shall, without consent of such




                                       35





stockholders,  reduce the amount or alter the form of the consideration that the
holders of the capital  stock of the Company  shall be entitled to receive  upon
the  Effective  Time  pursuant to Section  2.05  hereof.  Without  limiting  the
generality  of the  foregoing,  this  Agreement  may only be amended,  varied or
supplemented by an instrument in writing, signed by the parties hereto.





                                       36





                  IN WITNESS  WHEREOF,  the parties have  executed and delivered
this Agreement and Plan of Merger as of the day and year first above written.

         prior to  consummation of the Offer, as if made at and as of such time,
         provided that  representations  and warranties  made as of a particular
         date  need  be true  only as of such  date  (for  the  purpose  of this
         paragraph (f),  representations  and warranties of the Company that are
         expressly  qualified by a materiality  qualification  shall be true and
         correct  subject  to such  materiality  qualification,  and  all  other
         representations  and  warranties  shall  be  true  and  correct  in all
         material  respects);  and in any such  case,  such  breach,  failure or
         untruth  would  reasonably  be expected  to  materially  influence  the
         investment  decision of a reasonable  purchaser of all or a substantial
         portion of the Company's outstanding securities; or

                  (g)   all   consents,   approvals,   licenses,   certificates,
         accreditations,   authorizations   or   orders   of  any   governmental
         commission,  board or other regulatory body required in connection with
         the execution, delivery and performance of the Merger Agreement and for
         the Surviving  Corporation and the  Subsidiaries to conduct business in
         substantially  the manner conducted by the Company and the Subsidiaries
         as of the date of the Merger  Agreement,  shall not have been obtained,
         except  for any of the same,  the  failure  to obtain  which  would not
         reasonably be expected to have a Material Adverse Effect on the Company
         after  giving  effect to the  transactions  contemplated  by the Merger
         Agreement; or

                  (h)  the  Merger  Agreement  shall  have  been  terminated  in
         accordance  with its terms or amended in  accordance  with its terms to
         provide for such termination or amendment of the Offer; or

                  (i) all  members  of the Board of  Directors  of the  Company,
         other than two Continuing Directors, shall not have resigned, effective
         upon and subject only to the acceptance for payment by Acquisition  of,
         and deposit by  Acquisition  with the depositary for the Offer of funds
         sufficient  to make payment for, a majority of the  outstanding  Shares
         pursuant to the Offer,  or the Board of Directors of the Company  shall
         not have elected,  effective  upon and subject only to such  acceptance
         and  deposit,  at least  three  individuals  designated  by  Parent  as
         directors of the Company, effective upon such consummation,

which,  in the sole judgment of  Acquisition in any such case, and regardless of
the  circumstances  giving rise to any such  condition,  makes it inadvisable to
proceed with such acceptance for payment or payment.

The  foregoing  conditions  are for the sole benefit of  Acquisition  and may be
asserted or waived by  Acquisition in whole or in part at any time and from time
to time in its  sole  discretion.  The  failure  by  Acquisition  at any time to
exercise  any of the  foregoing  rights shall not be deemed a waiver of any such
right and each such right  shall be deemed an ongoing  right and may be asserted
at any time and from time to time.
