EXHIBIT A   -      Conditions of the Offer
 



                   AGREEMENT AND PLAN OF MERGER dated as of December 18, 1997,
              among INTERNATIONAL BUSINESS MACHINES CORPORATION, a New York
              corporation ("Parent"), HOOSIER ACQUISITION CORP., an Indiana
              corporation and a wholly owned subsidiary of Parent ("Sub"), and
              SOFTWARE ARTISTRY, INC., an Indiana corporation (the "Company").


         WHEREAS, Parent proposes to cause Sub to make a tender offer (as it
may be amended from time to time as permitted under this Agreement, the "Offer")
to purchase all the outstanding shares of Common Stock, no par value, of the
Company (the "Company Common Stock"; the outstanding shares of Company Common
Stock being hereinafter collectively referred to as the "Shares"), at a purchase
price (the "Offer Price") of $24.50 per Share, net to the seller in cash,
without interest thereon, upon the terms and subject to the conditions set forth
in this Agreement; and the Board of Directors of the Company has adopted
resolutions approving the Offer and recommending that holders of Shares accept
the Offer;

         WHEREAS, the merger of Sub with the Company (the "Merger") upon the
terms and subject to the conditions set forth in this Agreement, whereby each
issued and outstanding Share, other than Shares owned directly or indirectly by
Parent and, if applicable, Dissenting Shares (as defined in Section 3.01(d)),
will be converted into the right to receive in cash the price per share paid in
the Offer, has been authorized by all necessary corporate action on behalf of
Parent and Sub and has been adopted by the Board of Directors of the Company;

         WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent, Sub and certain
shareholders of the Company are entering into a Shareholder Agreement (the
"Shareholder Agreement") pursuant to which such shareholders have, among other
things, agreed to sell all such shareholders' Shares to Sub at the price per
Share paid in the Offer, upon the terms and subject to the conditions set forth
in the Shareholder Agreement; and the Shareholder Agreement has been approved by
the Board of Directors of the Company;

         WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent and certain
shareholders of the Company who are employed by the Company are entering into  

                        


Noncompetition Agreements (the "Noncompetition Agreements") pursuant to which
such shareholders have, among other things, agreed to not have any Relationship
(as defined in the Noncompetition Agreements) with certain third parties during
the Noncompetition Period (as defined in the Noncompetition Agreements); and

         WHEREAS, Parent, Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and the Merger and also to prescribe various conditions to the Offer and
the Merger.


         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Sub and the Company hereby agree as follows:


                                      ARTICLE I

                                      The Offer

         SECTION 1.01.  The Offer.  (a)  Subject to the provisions of this
Agreement, as promptly as practicable but in no event later than five business
days after the date of the public announcement by Parent and the Company of this
Agreement, Sub shall, and Parent shall cause Sub to, commence the Offer.  The
obligation of Sub to, and of Parent to cause Sub to, commence the Offer and
accept for payment, and pay for, any Shares tendered pursuant to the Offer shall
be subject only to the conditions set forth in Exhibit A (the "Offer
Conditions") (any of which may be waived in whole or in part by Sub in its
reasonable discretion, except that Sub shall not waive the Minimum Condition (as
defined in Exhibit A) without the consent of the Company) and to the terms and
conditions of this Agreement.  Sub expressly reserves the right to modify the
terms of the Offer, except that, without the consent of the Company, Sub shall
not (i) reduce the number of Shares subject to the Offer, (ii) reduce the Offer
Price, (iii) amend or add to the Offer Conditions, (iv) except as provided in
the next sentence, extend the Offer, (v) change the form of consideration
payable in the Offer or (vi) amend any other term of the Offer in any manner
adverse to the holders of the Shares.  Notwithstanding the foregoing, Sub may,
without the consent of the Company, (i) extend the Offer, if at the scheduled or
extended expiration date of the Offer any of the Offer Conditions shall not be
satisfied or waived, until such time as such conditions are satisfied or waived,
(ii) extend the 

                                       2



Offer for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer and (iii) extend the Offer for any reason on one
or more occasions for an aggregate period of not more than 10 business days
beyond the latest expiration date that would otherwise be permitted under
clause (i) or (ii) of this sentence.  Subject to the terms and conditions of the
Offer and this Agreement, Sub shall, and Parent shall cause Sub to, accept for
payment, and pay for, all Shares validly tendered and not withdrawn pursuant to
the Offer that Sub becomes obligated to accept for payment, and pay for,
pursuant to the Offer as promptly as practicable after the expiration of the
Offer.

         (b)  On the date of commencement of the Offer, Parent and Sub shall
file with the SEC a Tender Offer Statement on Schedule 14D-1 (the
"Schedule 14D-1") with respect to the Offer, which shall contain an offer to
purchase and a related letter of transmittal and summary advertisement (such
Schedule 14D-1 and the documents included therein pursuant to which the Offer
will be made, together with any supplements or amendments thereto, the "Offer
Documents").  Parent and Sub agree that the Offer Documents shall comply as to
form in all material respects with the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the rules and regulations promulgated
thereunder and the Offer Documents, on the date first published, sent or given
to the 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
covenant is made by Parent or Sub with respect to information supplied by the
Company or any of its shareholders specifically for inclusion or incorporation
by reference in the Offer Documents.  Each of Parent, Sub and the Company agree
promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that such information shall have become false or
misleading in any material respect, and Parent and Sub further agree to take all
steps necessary to cause the Schedule 14D-1 as so corrected to be filed with the
SEC and the other Offer Documents as so corrected to be disseminated to the
Company's shareholders, in each case as and to the extent required by applicable
federal securities laws.  The Company and its counsel shall be given reasonable
opportunity to review and comment upon the Offer Documents prior to their filing
with the SEC or dissemination to the shareholders of the Company.  Parent and
Sub agree to provide the Company 

                                       3


and its counsel any comments Parent, Sub 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 Sub on a timely
basis the funds necessary to accept for payment, and pay for, any Shares that
Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer.

         SECTION 1.02.  Company Actions.  (a)  The Company hereby approves of
and consents to the Offer and represents that the Board of Directors of the
Company, at a meeting duly called and held, duly and unanimously adopted
resolutions adopting this Agreement and authorizing the Company to execute and
deliver the Shareholder Agreement, approving the Offer and the Merger (and
effecting the other actions referred to in Section 4.15), determining that the
terms of the Offer and the Merger are fair to, and in the best interests of, the
Company's shareholders, recommending that the Company's shareholders accept the
Offer, tender their shares pursuant to the Offer and approve this Agreement (if
required) and approving the acquisition of Shares by Sub pursuant to the Offer
and the Shareholder Agreement and the other transactions contemplated by this
Agreement and the Shareholder Agreement.  The Company has been advised by each
of its directors and executive officers that each such person intends to tender
all Shares owned by such person pursuant to the Offer.

         (b)  On the date the Offer Documents are filed with the SEC, the
Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended from
time to time, the "Schedule 14D-9") containing the recommendation described in
paragraph (a) and shall mail the Schedule 14D-9 to the shareholders of the
Company.  The Company agrees that the Schedule 14D-9 shall comply as to form in
all material respects with the requirements of the Exchange Act and the rules
and regulations promulgated thereunder and, on the date filed with the SEC and
on the date first published, sent or given to the 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 covenant is made by the Company with respect to
information supplied by Parent or Sub specifically for inclusion in the
Schedule 14D-9.  Each of the Company, Parent and Sub agrees promptly to correct
any information provided by it for use in the Schedule 14D-9 if and to the
extent that such 

                                        4



information shall have become false or misleading in any material respect, and
the Company further agrees to take all steps necessary to amend or supplement
the Schedule 14D-9 and to cause the Schedule 14D-9 as so amended or supplemented
to be filed with the SEC and disseminated to the Company's shareholders, in each
case as and to the extent required by applicable federal securities laws. 
Parent and its counsel shall be given reasonable opportunity to review and
comment upon the Schedule 14D-9 prior to its filing with the SEC or
dissemination to shareholders of the Company.  The Company agrees to provide
Parent and its counsel any comments the Company or its counsel may receive from
the SEC or its staff with respect to the Schedule 14D-9 promptly after the
receipt of such comments.

         (c)  In connection with the Offer and the Merger, the Company shall
cause its transfer agent to furnish Sub promptly with mailing labels containing
the names and addresses of the record holders of Shares as of a recent date and
of those persons becoming record holders subsequent to such date, together with
copies of all lists of shareholders, security position listings and computer
files and all other information in the Company's possession or control regarding
the beneficial owners of Shares, and shall furnish to Sub such information and
assistance (including updated lists of shareholders, security position listings
and computer files) as Parent may reasonably request in communicating the Offer
to the Company's shareholders.  Subject to the requirements of applicable law,
and except for such steps as are necessary to disseminate the Offer Documents
and any other documents necessary to consummate the Merger, Parent and Sub and
their agents shall hold in confidence the information contained in any such
labels, listings and files, will use such information only in connection with
the Offer and the Merger and, if this Agreement shall be terminated, will, upon
request, deliver, and will use their reasonable efforts to cause their agents to
deliver, to the Company all copies and any extracts or summaries from such
information then in their possession or control.


                                      ARTICLE II

                                      The Merger

         SECTION 2.01.  The Merger.  Subject to the last two sentences of this

                                       5



the Effective Time (as defined in Section 2.03).  Following the Effective Time,
the separate corporate existence of Sub shall cease and the Company shall
continue as the surviving corporation (the "Surviving Corporation") and shall
succeed to and assume all the rights and obligations of Sub in accordance with
the IBCL.  At the election of Parent, any direct or indirect wholly owned
subsidiary (as defined in Section 10.03) of Parent may be substituted for and
assume all of the rights and obligations of Sub as a constituent corporation in
the Merger.  In such event, the parties agree to execute an appropriate
amendment to this Agreement in order to reflect the foregoing.

         SECTION 2.02.  Closing.  The closing of the Merger will take place at
10:00 a.m. (New York City time) on a date to be specified by Parent or Sub,
which shall be no later than the second business day after satisfaction or
waiver of the conditions set forth in Article VIII (the "Closing Date"), at the
offices of Cravath, Swaine & Xxxxx, Worldwide Plaza, 000 Xxxxxx Xxxxxx,
Xxx Xxxx, Xxx Xxxx 00000, unless another date, time or place is agreed to in
writing by the parties hereto.

         SECTION 2.03.  Effective Time.  Subject to the provisions of this 
Agreement, as soon as practicable on or after the Closing Date, the parties 
shall file articles of merger or other appropriate documents (in any such 
case, the "Articles of Merger") executed in accordance with the relevant 
provisions of the IBCL and shall make all other filings or recordings 
required under the IBCL. The Merger shall become effective at such time as 
the Articles of Merger are duly filed with the Indiana Secretary of State, or 
at such other time as Sub and the Company shall agree and shall be specified 
in the Articles of Merger (the time the Merger becomes effective being 
hereinafter referred to as the "Effective Time").

         SECTION 2.04.  Effects of the Merger.  The Merger shall have the
effects set forth in Section 23-1-40-6 of the IBCL.

         SECTION 2.05.  Articles of Incorporation and By-laws.  (a)  The Third
Amended and Restated Articles of Incorporation of the Company as in effect
immediately prior to the Effective Time shall be the articles of incorporation
of the Surviving Corporation, 


                                     6



until thereafter changed or amended as provided therein or by applicable law.

         (b)  The By-laws of the Company, as amended and restated and as in
effect immediately prior to the Effective Time, shall be the By-laws of the
Surviving Corporation, until thereafter changed or amended as provided therein
or by applicable law.

         SECTION 2.06.  Directors.  The directors of Sub immediately prior to
the Effective Time shall be the directors of the Surviving Corporation, until
the earlier of their resignation or removal or until their respective successors
are duly elected and qualified, as the case may be.

         SECTION 2.07.  Officers.  The officers of the Company immediately
prior to the Effective Time shall be the officers of the Surviving Corporation,
until the earlier of their resignation or removal or until their respective
successors are duly elected and qualified, as the case may be.


                                     ARTICLE III

                  Effect of the Merger on the Capital Stock of the 
                  Constituent Corporations; Exchange of Certificates

         SECTION 3.01.  Effect on Capital Stock.  As of the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
Shares or any shares of capital stock of Sub:

         (a)  Capital Stock of Sub.  Each issued and outstanding share of
    capital stock of Sub shall be converted into and become one fully paid and
    nonassessable share of Common Stock, no par value, of the Surviving
    Corporation.

         (b)  Cancelation of Treasury Stock and Parent Owned Stock.  Each Share
    that is owned by the Company and each Share that is owned by Parent or Sub
    shall automatically be canceled and retired and shall cease to exist, and
    no consideration shall be delivered in exchange therefor.

         (c)  Conversion of Shares.  Subject to Section 3.01(d), each issued
    and outstanding Share (other than Shares to be canceled in accordance with
    Section 3.01(b) and Shares owned by any subsidiary of the Company, Parent
    (other than Sub) or Sub) shall be converted into the right to receive from
    the Surviving Corporation in cash, without interest, the price per share
    paid in the Offer (the "Merger Consideration").  As of the Effective Time,
    all such Shares shall no longer be outstanding and shall automatically be
    canceled and retired and shall cease to exist, and each 


                                      7



    holder of a certificate representing any such Shares shall cease to have
    any rights with respect thereto, except the right to receive the Merger
    Consideration, without interest.

         (d)  Shares of Dissenting Shareholders.  Notwithstanding anything in
    this Agreement to the contrary, if the Merger is not effected pursuant to
    Section 23-1-40-4 of the IBCL, any issued and outstanding Shares held by a
    person (a "Dissenting Shareholder") who does not vote to approve the Merger
    and complies with all the provisions of the IBCL concerning the right of
    holders of Shares to dissent from the Merger and require payment of fair
    value (as defined in the IBCL) for their Shares ("Dissenting Shares") shall
    not be converted as described in Section 3.01(c), but shall be converted
    into the right to receive such consideration as may be determined to be due
    to such Dissenting Shareholder pursuant to the IBCL.  If, after the
    Effective Time, such Dissenting Shareholder withdraws his demand or fails
    to perfect or otherwise loses his rights as a Dissenting Shareholder to
    payment of fair value, in any case pursuant to the IBCL, his Shares shall
    be deemed to be converted as of the Effective Time into the right to
    receive the Merger Consideration.  The Company shall give Parent (i) prompt
    notice of any demands for fair value for Shares received by the Company and
    (ii) the opportunity to participate in and direct all negotiations and
    proceedings with respect to any such demands.  The Company shall not,
    without the prior written consent of Parent, make any payment with respect
    to, or settle, offer to settle or otherwise negotiate, any such demands.

         (e)  Withholding Tax.  The right of any shareholder to receive the
    Merger Consideration shall be subject to and reduced by the amount of any
    required tax withholding obligation.

         SECTION 3.02.  Exchange of Certificates.  (a)  Paying Agent.  Prior to
the Effective Time, Parent shall designate a bank or trust company to act as
paying agent in the Merger (the "Paying Agent"), and, from time to time on,
prior to or after the Effective Time, Parent shall make available, or cause the
Surviving Corporation to make available, to the Paying Agent cash in amounts and
at the times necessary for the prompt payment of the Merger Consideration upon
surrender of certificates formerly representing Shares as part of the Merger
pursuant to Section 3.01 (it being understood that any and all interest 


                                      8


earned on funds made available to the Paying Agent pursuant to this Agreement
shall be turned over to Parent).

         (b)  Exchange Procedure.  As soon as reasonably practicable after the
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates that immediately prior to the Effective Time
represented Shares (the "Certificates"), (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Paying
Agent and shall be in a form 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 to the Paying Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly executed,
and such other documents as may reasonably be required by the Paying Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor the
amount of cash into which the Shares theretofore represented by such Certificate
shall have been converted pursuant to Section 3.01, and the Certificate so
surrendered shall forthwith be canceled.  In the event of a transfer of
ownership of Shares that is not registered in the transfer records of the
Company, payment may be made to a person other than the person in whose name the
Certificate so surrendered is registered, if such Certificate shall be properly
endorsed or otherwise be in proper form for transfer and 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 such Certificate or
establish to the satisfaction of the Surviving Corporation that such tax has
been paid or is not applicable.  Until surrendered as contemplated by this
Section 3.02, each Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the amount of
cash, without interest, into which the Shares theretofore represented by such
Certificate shall have been converted pursuant to Section 3.01.  No interest
will be paid or will accrue on the cash payable upon the surrender of any
Certificate.

         (c)  No Further Ownership Rights in Shares.  All cash paid upon the
surrender of Certificates in accordance with the terms of this Article III shall
be deemed to have been paid in full satisfaction of all rights pertaining to the
Shares theretofore represented by such Certificates.  At the Effective Time, the
stock transfer books of the Company shall be closed, and there shall be no
further registration 

                                       9



of transfers on the stock transfer books of the Surviving Corporation of the
Shares that were outstanding immediately prior to the Effective Time.  If, after
the Effective Time, Certificates are presented to the Surviving Corporation or
the Paying Agent for any reason, they shall be canceled and exchanged as
provided in this Article III.

         (d)  No Liability.  None of Parent, Sub, the Company or the Paying
Agent shall be liable to any person in respect of any cash 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 seven years after
the Effective Time (or immediately prior to such earlier date on which any
payment pursuant to this Article III would otherwise escheat to or become the
property of any Governmental Entity (as defined in Section 4.05)), the cash
payment 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 interests of any person previously entitled thereto.


                                      ARTICLE IV

                    Representations and Warranties of the Company

         Except as set forth in the disclosure schedule delivered by the
Company to Parent prior to the execution of this Agreement (the "Company
Disclosure Schedule"), the Company represents and warrants to Parent and Sub as
follows:

         SECTION 4.01.  Organization.  The Company and each of its Significant
Subsidiaries (as defined in Section 10.03) is a corporation duly organized,
validly existing and in good standing (to the extent the jurisdiction recognizes
such concept) under the laws of the jurisdiction of its organization and has all
requisite corporate power and authority to carry on its business as now being
conducted.  The Company and each of its Significant Subsidiaries is duly
qualified or licensed to do business and in good standing in each jurisdiction
in which the property owned, leased or operated by it or the nature of the
business conducted by it makes such qualification or licensing necessary, except
in such jurisdictions where the failure to be so duly qualified or licensed and
in good standing would not have a material adverse effect (as defined in
Section 10.03) on the Company or prevent or materially delay the consummation of
the Offer and/or the Merger.  The Company has delivered to Parent complete and 


                                10


correct copies of its Third Amended and Restated Articles of Incorporation and
By-laws, as amended and restated and the articles of incorporation and by-laws
(or similar organizational documents) of its Significant Subsidiaries.

         SECTION 4.02.  Subsidiaries.  Schedule 4.02 lists each subsidiary of
the Company.  All the outstanding shares of capital stock of each such
subsidiary are owned by the Company, by another wholly owned subsidiary  of the
Company or by the Company and another wholly owned subsidiary of the Company,
free and clear of all pledges, claims, liens, charges, encumbrances and security
interests of any kind or nature whatsoever (collectively, "Liens"), and are duly
authorized, validly issued, fully paid and nonassessable.  Except for the
capital stock of its subsidiaries, the Company does not own, directly or
indirectly, any capital stock or other ownership interest in any corporation,
partnership, joint venture or other entity. 

         SECTION 4.03.  Capitalization.  The authorized capital stock of the
Company consists of 10,000,000 Shares.  At the close of business on December 17,
1997, (i) 7,085,433 Shares were issued and outstanding and (ii) 1,726,205 Shares
were reserved for issuance upon exercise of options to purchase Shares ("Company
Stock Options").  Except as set forth above, as of the close of business on
December 17, 1997, no shares of capital stock or other voting securities of the
Company were issued, reserved for issuance or outstanding.  All outstanding
shares of capital stock of the Company are, and all shares which may be issued
will be, when issued, duly authorized, validly issued, fully paid and
nonassessable and not subject to preemptive rights.  There are no bonds,
debentures, notes or other indebtedness of the Company having the right to vote
(or convertible into, or exchangeable for, securities having the right to vote)
on any matters on which shareholders of the Company may vote.  Except as set
forth above, as of the date of this Agreement, there are no securities, options,
warrants, calls, rights, commitments, agreements, arrangements or undertakings
of any kind to which the Company or any of its subsidiaries is a party or by
which the Company or any of its subsidiaries is bound obligating the Company or
any of its subsidiaries to issue, deliver or sell, or cause to be issued,
delivered or sold, additional shares of capital stock or other voting securities
of the Company or any of its subsidiaries.  As of the date of this Agreement,
there are no outstanding contractual obligations of the Company or any of its
subsidiaries to repurchase, redeem or otherwise acquire any shares of capital
stock of the Company or to vote or to dispose of any shares of the capital stock
of any of the Company's subsidiaries.


                                      11



         SECTION 4.04.  Authority.  The Company has the requisite corporate
power and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby (subject to, with respect to the Merger, if the
Merger is not effected pursuant to Section 23-1-40-4 of the IBCL, the approval
of this Agreement by the holders of a majority of the Shares (the "Company
Shareholder Approval")).  The execution, delivery and performance of this
Agreement and the consummation by the Company of the Merger and of the other
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement or to
consummate the transactions so contemplated (in each case, other than, with
respect to the Merger, the Company Shareholder Approval (if required)).  This
Agreement has been duly executed and delivered by the Company and, assuming this
Agreement constitutes a valid and binding obligation of Parent and Sub,
constitutes a valid and binding obligation of the Company enforceable against
the Company in accordance with its terms.

         SECTION 4.05.  Consents and Approvals; No Violations.  Except for
filings, permits, authorizations, consents and approvals as may be required
under, and other applicable requirements of, the Exchange Act (including the
filing with the SEC of the Schedule 14D-9 and a proxy statement relating to the
Company Shareholder Approval, if required (the "Proxy Statement")), the
Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), the IBCL, Section 23-2-3.1 et seq. of the Indiana Code or the laws of
other states in which the Company is qualified to do or is doing business,
neither the execution, delivery or performance of this Agreement by the Company
nor the consummation by the Company of the transactions contemplated hereby will
(i) conflict with or result in any breach of any provision of the Third Amended
and Restated Articles of Incorporation or By-laws, as amended and restated, of
the Company or any of the similar organizational documents of any of its
Significant Subsidiaries, (ii) require any filing with, or permit,
authorization, consent or approval of, any federal, state or local government or
any court, tribunal, administrative agency or commission or other governmental
or regulatory authority or agency, domestic, foreign or supranational (a
"Governmental Entity") (except where the failure to make such filings or to
obtain such permits, authorizations, consents or approvals would not have a
material adverse effect on the Company or prevent or materially delay the
consummation of the Offer and/or the Merger), (iii) result in a violation or
breach of, or constitute (with or without 

                                     12



due notice or lapse of time or both) a default under, or give rise to any right
of termination, amendment, cancelation or acceleration under, or result in the
creation of any Lien upon any of the properties or assets of the Company or any
of its subsidiaries under, any of the terms, conditions or provisions of any
note, bond, mortgage, indenture, lease, license, permit, concession, franchise,
contract, agreement or other instrument or obligation (a "Contract") to which
the Company or any of its subsidiaries is a party or by which any of its
properties or assets may be bound or (iv) violate any judgment, order, writ,
preliminary or permanent injunction or decree (an "Order") or any statute, law,
ordinance, rule or regulation of any Governmental Entity (a "Law") applicable to
the Company, any of its subsidiaries or any of their properties or assets,
except in the case of clauses (iii) or (iv) for violations, breaches or defaults
that could not reasonably be expected to have a material adverse effect on the
Company or prevent or materially delay the consummation of the Offer and/or the
Merger.

         SECTION 4.06.  SEC Reports and Financial Statements.  The Company 
and each of its subsidiaries has filed with the SEC, and has heretofore made 
available to Parent, true and complete copies of, all forms, reports, 
schedules, statements and other documents required to be filed by it since 
January 1, 1996 under the Exchange Act or the Securities Act of 1933 (the 
"Securities Act") (such forms, reports, schedules, statements and other 
documents, including any financial statements or schedules included therein, 
are referred to as the "Company SEC Documents").  The Company SEC Documents, 
at the time filed, (a) did not contain any untrue statement of a material 
fact or omit to state a 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 and (b) complied in 
all material respects with the applicable requirements of the Exchange Act 
and the Securities Act, as the case may be, and the applicable rules and 
regulations of the SEC thereunder.  Except to the extent that information 
contained in any Company SEC Document has been revised or superseded by a 
subsequently filed Company Filed SEC Document (as defined in Section 4.07) (a 
copy of which has been made available to Parent prior to the date hereof), 
none of the Company SEC Documents contains an untrue statement of a material 
fact or omits to state a material fact required to be stated or incorporated 
by reference therein or necessary in order to make the statements therein, in 
light of the circumstances under which they were made, not misleading.  The 
financial statements of the Company included in the Company SEC 

                                     13



Documents comply as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto, have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto or, in the case of the
unaudited statements, as permitted by Form 10-Q of the SEC) and fairly present
(subject, in the case of the unaudited statements, to normal, recurring audit
adjustments) the consolidated financial position of the Company and its
consolidated subsidiaries as at the dates thereof and the consolidated results
of their operations and cash flows for the periods then ended.

         SECTION 4.07.  Absence of Certain Changes or Events.  Except as
disclosed in the Company SEC Documents filed and publicly available prior to the
date of this Agreement (the "Company Filed SEC Documents"), since December 31,
1996, the Company and its subsidiaries have conducted their respective business
only in the ordinary course, and there has not been (i) any material adverse
change (as defined in Section 10.03) with respect to the Company, (ii) any
declaration, setting aside or payment of any dividend or other distribution with
respect to its capital stock or any redemption, repurchase or other acquisition
of any of its capital stock, (iii) any split, combination or reclassification of
any of its capital stock or any issuance or the authorization of any issuance of
any other securities in respect of, in lieu of or in substitution for shares of
its capital stock, (iv) (x) any granting by the Company or any of its
subsidiaries to any officer of the Company or any of its subsidiaries of
any increase in compensation (including in connection with promotions), except
in the ordinary course of business  consistent with past practice or as was
required under employment agreements in effect as of December 31, 1996, (y) any
granting by the Company or any of its subsidiaries to any such officer of any
increase in severance or termination pay, except as required under employment,
severance or termination agreements in effect as of December 31, 1996, or
(z) except employment or consulting agreements in the ordinary course of
business consistent with past practice with employees other than any executive
officer of the Company, any entry by the Company or any of its subsidiaries into
any employment or consulting agreement, with any such employee or executive
officer, (v) any damage, destruction or loss, whether or not covered by
insurance, that has or reasonably could be expected to have a material adverse
effect on the Company, (vi) any revaluation by the Company of any of its
material assets, 

                                      14


(vii) any material change in accounting methods, principles or practices by the
Company or (viii) (A) any licensing or other agreement with regard to the
acquisition or disposition of any material Intellectual Property (as defined in
Section 4.18) or rights thereto other than sales or licenses of its products to
customers in the ordinary course of business consistent with past practice or
(B) any amendment or consent with respect to any licensing or other agreement
described in clause (A) above.

         SECTION 4.08.  No Undisclosed Liabilities.  Except as and to the
extent set forth in the Company Filed SEC Documents, neither the Company nor any
of its subsidiaries has any liabilities of any nature, whether or not accrued,
contingent or otherwise, that would be reasonably expected to have a material
adverse effect on the Company.

         SECTION 4.09.  Information Supplied.  None of the information supplied
or to be supplied by the Company specifically for inclusion or incorporation by
reference in (i) the Offer Documents, (ii) the Schedule 14D-9, (iii) the
information to be filed by the Company in connection with the Offer pursuant to
Rule 14f-1 promulgated under the Exchange Act (the "Information Statement") or
(iv) the Proxy Statement, will, in the case of the Offer Documents, the
Schedule 14D-9 and the Information Statement, at the respective times the Offer
Documents, the Schedule 14D-9 and the Information Statement are filed with the
SEC or first published, sent or given to the Company's shareholders, or, in the
case of the Proxy Statement, at the time the Proxy Statement is first mailed to
the Company's shareholders or at the time of the Shareholders Meeting (as
defined in Section 7.01), 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 are made, not misleading.  The Schedule 14D-9, the Information Statement
and the Proxy Statement will comply as to form in all material respects with the
requirements of the Exchange Act and the rules and regulations thereunder,
except that no representation or warranty is made by the Company with respect to
statements made or incorporated by reference therein based on information
supplied by Parent or Sub specifically for inclusion or incorporation by
reference therein.

         SECTION 4.10.  Benefit Plans; Employees and Employment Practices. 
(a)  Except as disclosed in the Company Filed SEC Documents, since December 31,
1996, there has not been any adoption or amendment in any material respect
(including any increase or improvements in benefits 


                                      15



or coverage) by the Company or any of its subsidiaries of any Benefit Plan (as
defined in Section 4.10(b)).  Except as disclosed in the Company Filed SEC
Documents, there exist no employment or consulting agreements, or any other
similar arrangements or understandings (whether or not in writing), between the
Company or any of its subsidiaries and any current or former employee, officer
or director of the Company or any of its subsidiaries.

         (b)  Schedule 4.10(b) lists each "employee pension benefit plan" (as
defined in Section 3(2) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA") (sometimes referred to herein as "Pension Plans"),
"employee welfare benefit plan" (as defined in Section 3(1) of ERISA), bonus,
deferred compensation, incentive compensation, stock ownership, stock purchase,
stock option, phantom stock, retirement, vacation, severance, change of control,
disability, death benefit, hospitalization, medical, fringe benefit, excess
benefit, supplemental executive compensation, stock appreciation, restricted
stock, indemnification, collective bargaining agreement or other material
employee benefit plan, policy, agreement, arrangement or understanding (whether
or not in writing) providing benefits to any current or former employee,
officer, director or independent contractor of the Company or any of its
subsidiaries or any entity that is or required under Section 414 of the Code to
be treated with the Company as a single employer (an "ERISA Affiliate") or with
respect to which the Company or any ERISA Affiliate could have any liability
(collectively, the "Benefit Plans").  The Company has made available to Parent
true, complete and correct copies of (i) each Benefit Plan (or, in the case of
any unwritten Benefit Plans, descriptions thereof) and each employment and
consulting agreement, arrangement or understanding between the Company or any of
its subsidiaries and any current or former employee, officer or director of the
Company or any of its subsidiaries, (ii) the most recent annual report on
Form 5500 (and related schedules and financial statements or opinions required
in connection therewith) filed with the Internal Revenue Service with respect to
each Benefit Plan (if any such report was required), (iii) the most recent
actuarial report with respect to each Benefit Plan, as applicable, (iv) the most
recent summary plan description (and a summary of material modifications, if
applicable) for each Benefit Plan, (v) each trust agreement and group annuity
contract relating to any Benefit Plan, and (vi) the most recent determination
letter, if any, issued with respect to such Benefit Plan.

         (c)  Each Benefit Plan has been administered in all material respects
in accordance with its terms and the 


                                     16



applicable requirements of ERISA, the Internal Revenue Code of 1986, as amended
(the "Code") and all other applicable laws.  No event has occurred and to the
knowledge of the Company there exists no condition or set of conditions in
connection with the Benefit Plans that, individually or in the aggregate, could
have a material adverse effect on, or give rise to material liability to, the
Company or any ERISA Affiliate under ERISA, the Code or any other applicable
law.

         (d)  Each Pension Plan intended to be qualified under Section 401(a)
of the Code has been the subject of a determination letter from the Internal
Revenue Service to the effect that such Pension Plan is so qualified under all
currently applicable provisions of Section 401(a) of the Code and, to the
knowledge of the Company, no circumstances exist that would adversely affect the
qualification of any such Pension Plan.  

         (e)  No Benefit Plan is subject to Title IV of ERISA.

         (f)  Each Benefit Plan may be amended or terminated without material
liability to the Company or any ERISA Affiliate.

         (g)  The Company has previously delivered to Parent a list which sets
forth the names of all current officers, directors and employees of the Company
and each of its subsidiaries, together with each employee's current salary and
date of employment.  

         (h)  (i) There are no material controversies, strikes, work stoppages
or disputes pending or threatened between the Company or any of its subsidiaries
and any current or former employees, (ii) no labor union or other collective
bargaining unit represents or has ever represented any employee of the Company
or any of its subsidiaries with respect to employment by the Company or such
subsidiary and (iii) no organizational effort by any labor union or other
collective bargaining unit currently is under way or threatened with respect to
any employee.  

         SECTION 4.11.  Contracts.  Except as disclosed in the Company Filed
SEC Documents and except for Contracts that have previously been delivered to
Parent, there are no Contracts that are material to the business, properties,
financial condition or results of operations of the Company and its subsidiaries
taken as a whole.  Neither the Company nor any of its subsidiaries is in
violation or breach of or in default under (nor does there exist any condition
which upon the passage of time or the giving of notice would cause 


                                         17


such a violation or breach of or default under) any Contract to which it is a
party or by which it or any of its properties or assets is bound, except for
violations, breaches or defaults that could not reasonably be expected to have a
material adverse effect on the Company.

         SECTION 4.12.  Litigation.  Except as disclosed in the Company Filed
SEC Documents, there is no suit, claim, action, proceeding or investigation
pending before any Governmental Entity or, to the best knowledge of the Company,
threatened against the Company or any of its subsidiaries that could reasonably
be expected to have a material adverse effect on the Company or prevent or
materially delay the consummation of the Offer and/or the Merger.  Except as
disclosed in the Company Filed SEC Documents, neither the Company nor any of its
subsidiaries is subject to any outstanding Order that could reasonably be
expected to have a material adverse effect on the Company or prevent or
materially delay the consummation of the Offer and/or the Merger.

         SECTION 4.13.  Compliance with Applicable Law.  The Company and its
subsidiaries hold all permits, licenses, variances, exemptions, orders and
approvals of all Governmental Entities necessary for the lawful conduct of their
respective businesses (the "Company Permits"), except for failures to hold such
Company Permits that would not have a material adverse effect on the Company or
prevent or materially delay the consummation of the Offer and/or the Merger. 
The Company and its subsidiaries are in compliance with the terms of the Company
Permits, except where the failure so to comply would not have a material adverse
effect on the Company or prevent or materially delay the consummation of the
Offer and/or the Merger.  Except as disclosed in the Company Filed SEC
Documents, to the best knowledge of the Company, the businesses of the Company
and its subsidiaries are not being conducted in violation of any Law, except for
possible violations that would not have a material adverse effect on the Company
or prevent or materially delay the consummation of the Offer and/or the Merger. 
As of the date of this Agreement, no investigation or review by any Governmental
Entity with respect to the Company or any of its subsidiaries is pending or, to
the best knowledge of the Company, threatened, nor has any Governmental Entity
indicated an intention to conduct any such investigation or review, other than,
in each case, those the outcome of which would not be reasonably expected to

         SECTION 4.14.  Tax Matters.

         (a)  The Company and each of its subsidiaries has timely filed all
federal, state and local, domestic and foreign, income and franchise tax returns
and reports and all other material tax returns and reports required to be filed
by it.  All such returns and reports are complete and correct in all material
respects.  The Company and each of its subsidiaries has timely paid (or the
Company has paid on its subsidiaries' behalf) all taxes due with respect to the
taxable periods covered by such returns and reports and all other material taxes
(as defined below), and the most recent financial statements contained in the
Company Filed SEC Documents reflect an adequate reserve for all taxes payable by
the Company and its subsidiaries for all taxable periods and portions thereof
through the date of such financial statements.

         (b)  No federal, state or local, domestic or foreign, income or
franchise tax return or report or any other material tax return or report of the
Company or any of its subsidiaries is under audit or examination by any taxing
authority, and no written or unwritten notice of such an audit or examination
has been received by the Company.  Each material deficiency resulting from any
audit or examination relating to taxes by any taxing authority has been timely
paid.  No material issues relating to taxes were raised by the relevant taxing
authority during any presently pending audit or examination, and no material
issues relating to taxes were raised by the relevant taxing authority in any
completed audit or examination that can reasonably be expected to recur in a
later taxable period.  No federal, state or local, domestic or foreign, tax
return or report of the Company or any of its subsidiaries has ever been under
audit or examination by the Internal Revenue Service or other relevant taxing
authority, except for federal income tax examinations for 1994 and 1995 and
Indiana tax examinations for 1993, 1994 and 1995.  The relevant statute of
limitations is closed with respect to the U.S. federal tax returns of the
Company and its subsidiaries for all years through 1993.

         (c)  There is no agreement or other document extending, or having the
effect of extending, the period of assessment or collection of any taxes and no
power of attorney with respect to any taxes has been executed or filed with any
taxing authority.  

         (d)  No material liens for taxes exist with respect to any assets or
properties of the Company or any of 



                                      19




its subsidiaries, except for statutory liens for taxes not yet due.  

         (e)  Neither the Company nor any of its subsidiaries is a party to or
bound by any tax sharing agreement, tax indemnity obligation or similar
agreement, arrangement or practice with respect to taxes (including any advance
pricing agreement, closing agreement or other agreement relating to taxes with
any taxing authority).  

         (f)  Neither the Company nor any of its subsidiaries will be required
to include in a taxable period ending after the Effective Time taxable income
attributable to income that accrued in a prior taxable period but was not
recognized in any prior taxable period as a result of the installment method of
accounting, the completed contract method of accounting, the long-term contract
method of accounting, the cash method of accounting or Section 481 of the Code
or comparable provisions of state or local tax law, domestic or foreign, or for
any other reason.  

         (g)  The disallowance of a deduction under Section 162(m) of the Code
for employee remuneration will not apply to any amount paid or payable by the
Company or any of its subsidiaries under any Benefit Plan or other compensation
arrangement currently in effect.

         (h)  Any amount or other entitlement that could be received (whether
in cash or property or the vesting of property) as a result of any of the
transactions contemplated by this Agreement by any employee, officer or director
of the Company or any of its affiliates who is a "disqualified individual" (as
such term is defined in proposed Treasury Regulation Section 1.280G-1) under any
Benefit Plan or other compensation arrangement currently in effect would not be
characterized as an "excess parachute payment" or a "parachute payment" (as such
terms are defined in Section 280G(b)(1) of the Code).

         (i)  The Company has complied in all respects with all applicable
laws, rules and regulations relating to the payment and withholding of taxes
(including, without limitation, withholding of taxes pursuant to Sections 1441,
1442, 3121 and 3402 of the Code or similar provisions under any foreign federal
laws or any state or local laws, domestic and foreign)  and has, within the time
and the manner prescribed by law, withheld from and paid over to the proper
governmental authorities all amounts required to be so withheld and paid over
under applicable laws.



                                       20




         (j)  As used in this Agreement, "taxes" shall include all federal, 
state and local, domestic and foreign, income, franchise, property, sales, 
excise, employment, payroll, social security, value-added, ad valorem, 
transfer, withholding and other taxes, including taxes based on or measured 
by gross receipts, profits, sales, use or occupation, tariffs, levies, 
impositions, assessments or governmental charges of any nature whatsoever, 
including any interest penalties or additions with respect thereto.

         SECTION 4.15.  State Takeover Statutes.  The Board of Directors of the
Company has (i) adopted a by-law providing that Chapter 42 of the IBCL does not
apply to control share acquisitions of Shares and (ii) adopted this Agreement
and approved the Offer, the Shareholder Agreement, the acquisition of Shares by
Sub pursuant to the Offer and the Shareholder Agreement and the other
transactions contemplated by this Agreement and the Shareholder Agreement, and
such adoptions and approvals are sufficient to render inapplicable to the Offer,
the Merger, this Agreement, the Shareholder Agreement, the acquisition of Shares
by Sub pursuant to the Offer and the Shareholder Agreement and the other
transactions contemplated by this Agreement and the Shareholder Agreement the
provisions of Chapters 42 and 43 of the IBCL.  To the best knowledge of the
Company, no other state takeover statute (other than Section 23-2-3.1 et seq. of
the IBCL) or similar Law applies or purports to apply to the Offer, the Merger,
this Agreement, the Shareholder Agreement, the acquisition of Shares by Sub
pursuant to the Offer and the Shareholder Agreement or any of the transactions
contemplated by this Agreement or the Shareholder Agreement.

         SECTION 4.16.  Brokers; Schedule of Fees and Expenses.  No broker,
investment banker, financial advisor or other person, other than Broadview
Associates, the fees and expenses of which will be paid by the Company (as
reflected in an agreement between such firm and the Company, a copy of which has
been delivered to Parent), is entitled to any broker's, finder's, financial
advisor's or other similar fee or commission in connection with the transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
the Company.

         SECTION 4.17.  Opinion of Financial Advisor.  The Company has received
the opinion of Broadview Associates, dated the date of this Agreement, to the
effect that, as of the date of this Agreement, the consideration to be received
in the Offer and the Merger by the Company's shareholders is fair to the
Company's shareholders from a financial point of view, and a complete and
correct signed copy of such opinion 


                                    21



has been, or promptly upon receipt thereof will be, delivered to Parent.

         SECTION 4.18.  Intellectual Property.  (a)  The Company has provided
Parent with true and correct copies of all Contracts relating to Intellectual
Property to which the Company or any of its subsidiaries is a party except that,
with respect to employee confidentiality agreements, the Company has provided
Parent with a specimen of the form of agreement signed by all former and current
employees, agents, consultants and contractors who have contributed to or
participated in the conception and development of computer software or other
Intellectual Property of the Company or any of its subsidiaries.

         (b)  Except to the extent that the inaccuracy of any of the following
(or the circumstances giving rise to such inaccuracy) would not have a material
adverse effect on the Company:

         (1) the Company and each of its subsidiaries owns, or is licensed or
    otherwise has the right to use (in each case, clear of any Liens), all
    Intellectual Property used in or necessary for the conduct of its business
    as currently conducted;

         (2) there is no suit, claim, action, investigation or proceeding
    pending or, to the best knowledge of the Company, threatened that the
    Company or any of its subsidiaries is infringing on or otherwise violating
    the rights of any person with regard to any Intellectual Property owned by,
    licensed to and/or otherwise used by the Company or any of its
    subsidiaries;

         (3) to the best knowledge of the Company, no person is infringing on
    or otherwise violating any right of the Company or any of its subsidiaries
    with respect to any Intellectual Property owned by, licensed to and/or
    otherwise used by the Company or any of its subsidiaries;

         (4) none of the former or current members of management or key
    personnel of the Company or any of its subsidiaries, including all former
    and current employees, agents, consultants and contractors who have
    contributed to or participated in the conception and development of
    computer software or other Intellectual Property of the Company or any of
    its subsidiaries, has asserted or threatened in writing any claim against
    the Company or any of its subsidiaries in connection with 


                                       22



    the involvement of such persons in the conception and development of any
    computer software or other Intellectual Property of the Company or any of
    its subsidiaries and to the best knowledge of the Company no basis exists
    for any such claim;

         (5) the execution and delivery of this Agreement, compliance with its
    terms and the consummation of the transactions contemplated hereby do not
    and will not conflict with or result in any violation, breach or default
    (with or without notice or lapse of time or both) under, or give rise to
    any right, license or Lien relating to, Intellectual Property owned by the
    Company or any of its subsidiaries or with respect to which the Company or
    any of its subsidiaries now has or has had any Contract with any third
    party, or any right of termination, cancelation or acceleration of any
    material Intellectual Property right or obligation set forth in any
    agreement to which the Company or any of its subsidiaries is a party, or
    the loss or encumbrance of any Intellectual Property or material benefit
    related thereto, or result in or require the creation, imposition or
    extension of any Lien upon any Intellectual Property or right;

         (6) no licenses or rights have been granted to distribute the source
    code of, or to use the source code to create Derivative Works (as
    hereinafter defined) of, any product currently marketed by, commercially
    available from or under development by the Company or any of its
    subsidiaries other than applications source code written in SA-Script
    (formerly known as KML); and

         (7) the Company and each of its subsidiaries has taken reasonable and
    necessary steps to protect its Intellectual Property and their rights
    thereunder, and to the best knowledge of the Company, no such rights to
    Intellectual Property have been lost or are in jeopardy of being lost
    through failure to act by the Company or any of its subsidiaries.

         As used herein, "Derivative Work" shall mean a work that is based upon
one or more preexisting works, such as a revision, enhancement, modification,
abridgement, condensation, expansion or any other form in which such preexisting
works may be recast, transformed or adapted, and which, if prepared without

constitute a copyright infringement.  For purposes hereof, a Derivative Work
shall also include any compilation that incorporates 


                                     23




such a preexisting work as well as translations from one human language to
another and from one type of code to another.

jurisdiction of its incorporation and has all requisite corporate power and

power and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby.  The execution, delivery and

(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, amendment, cancelation or acceleration) under, any of
the terms, conditions or provisions of any Contract to which Parent or any of
its subsidiaries is a party or by which any of them or any of their properties
or assets may be bound or (iv) violate any Order or Law applicable to Parent,
any of its subsidiaries or any of their properties or assets, except in the case
