Item 2.  Acquisition or Disposition of Assets

On June 3, 1996, 1176484 Ontario Inc., a wholly-owned subsidiary of Transaction
Systems Architects, Inc. (TSA or the Company), organized under federal law of
Canada, acquired substantially all of the net assets of TXN Solution Integrators
(TXN), a Canadian partnership. TSA is in the process of changing the name of
1176484 Ontario Inc. to Applied Communications Canada, Inc.  TXN's ultimate
parent company is Tandem Computers Incorporated (Tandem).  The purchase price
was approximately $3.6 million in cash and the assumption of certain liabilities
of TXN.  The purchase price will be adjusted based upon the change in certain of
TXN's net assets from April 30, 1996 to May 31, 1996.  The cash purchase price
was paid out of existing TSA corporate funds.  The acquired assets consisted
primarily of accounts receivable, fixed assets, software, contract rights and
goodwill.

TXN distributes and supports computer software, acts as a solution integrator
and provides facilities management services.  TXN was the exclusive distributor
of BASE24 products in Canada for Applied Communications, Inc., a wholly-owned
subsidiary of TSA.

The Company's primary product line, BASE24, operates on Tandem computers. The 
Company has a number of agreements with Tandem that cover such items as 
commissions on the sale of certain Tandem products, certain limited resales 
by the Company of Tandem products and the distribution of the Company's 
products by Tandem affiliates in a limited number of countries.

Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits

(a)      Financial statements of businesses acquired.

         Audited financial statements of TXN for the year ended September

right to use or a valid leasehold interest in, the properties and assets used by
it, located on its premises, or shown on the Most Recent Balance Sheet or

purpose of preparing Tandem's consolidated financial statements.

Taxes.  The Target has made all deposits required by law to be made with respect

                                          14

tax-sharing or allocation agreement, nor does the Target owe any amount under
any tax-sharing or allocation agreement.  The Target has delivered to Buyer true
and correct copies of all Tax Returns for years ended and filed on or before the
Closing.  All Tax Returns filed by the Target after the Closing for any periods,
property or events on or before the Closing shall properly reflect the
liabilities of the Target for Taxes for such periods, property or events on or

    addressed to the Target, and dated as of the Closing Date;

         (viii) All actions to be taken by the Buyer in connection with
    consummation of the transactions contemplated hereby and all certificates,
    opinions, instruments,

                                          29



    and other documents required to effect the transactions contemplated hereby
    will be reasonably satisfactory in form and substance to the Target;

         (ix) Buyer shall have agreed to a lease on the same terms as those
    presently in effect for Target the space presently occupied by Target on
    Floors 19, 20 and 21 of the building located at 155 University Avenue,

         completion of the Closing on terms satisfactory to Buyer, provided,
         however, that nothing herein shall be deemed to require the Buyer to
         continue the employment of such Employees for any particular period of
         time; and nothing herein shall be deemed to be for the benefit of any
         such Employee or give any such Employee the right to be retained in
         the employ of the Buyer or to interfere with the right of the Buyer to
         terminate the employment of any such Employee at any time.

              (ii) The Target acknowledges that it is responsible for and
         agrees to indemnify and save harmless the Buyer from all Claims
         incurred by the Buyer if, solely as a result of this sale of the
         Target's assets, any employee of the Target exercises his legal right
         to consider himself terminated by the transaction and seeks from the
         Buyer any statutory payments or common law damages as a consequence of
         such termination or deemed termination of employment.

              (iii) The Target agrees that it shall, as at the Closing Date,

         legislation related to employment matters.

The Target may waive any condition specified in this Section 6(b) if it executes
a writing so stating at or prior to the Closing.

    7.   TERMINATION OF AGREEMENT. The Buyer and the Target may terminate this
Agreement by mutual written consent at any time prior to the Closing.  If any
Party terminates this Agreement, all rights and obligations of the Parties
hereunder shall terminate without any Liability of any Party to any other Party.

    8.   POST-CLOSING COVENANTS.   The Parties agree as follows with respect to
the period following the Closing:

    (a)  GENERAL.   In case at any time after the Closing any further action is
necessary or desirable to carry out the purposes of this Agreement, each of the
Parties will take such further action (including the execution and delivery of
such further instruments and documents) as any other Party reasonably may
request, all at the sole cost and expense of the requesting Party (unless the
requesting Party is entitled to indemnification therefor under Section 9 below).
The Target Owners and Tandem acknowledge and agree that from and after the
Closing the Buyer will be entitled to possession of all documents, books,
records, agreements, and data relating to the Acquired Assets and Assumed
Liabilities of the Target.

    (b)  LITIGATION SUPPORT.  In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this  Agreement, or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving the Target, each of the other Parties will
cooperate with the contesting or defending Party and its counsel in the contest
or defense, make available its personnel, and


                                          31



provide such testimony and access to its books and records as shall be necessary
in connection with the contest or defense, all at the sole cost and expense of
the contesting or defending Party (unless the contesting or defending Party is
entitled to indemnification therefor under Section 9 below).

    (c)  TRANSITION.  None of the Target Owners or Tandem will take any action
that is designed or intended to have the effect of discouraging any lessor,
licensor, customer, supplier, or other business associate of the Target from
maintaining the same business relationships with the Buyer after the Closing as
it maintained with the Target prior to the Closing. Each of the Target, the
Target Owners and Tandem will refer all customer inquiries relating to the
business of the Target to the Buyer from and after the Closing.

    (d)  CONFIDENTIALITY.   Each of the Target Owners and Tandem will treat and
hold as such all of the Confidential Information, refrain from using any of the
Confidential Information except in connection with this Agreement, and deliver
promptly to the Buyer or destroy, at the request and option of the Buyer, all
tangible embodiments (and all copies) of the Confidential Information which are
in its possession. In the event that any of the Target Owners and Tandem is
requested or required (by oral question or request for information or documents
in any legal proceeding, interrogatory, subpoena, civil investigative demand, or
similar process) to disclose any Confidential Information, that Target Owners
and Tandem will notify the Buyer promptly of the request or requirement so that
the Buyer may seek an appropriate protective order or waive compliance with this
provision.  If, in the absence of a protective order or the receipt of a waiver
hereunder, any of the Target Owners and Tandem is, on the advice of counsel,
compelled to disclose any Confidential Information to any tribunal or else stand
liable for contempt, that Target Owners and Tandem may disclose the Confidential
Information to the tribunal; PROVIDED, HOWEVER, that the disclosing Target
Owners and Tandem shall use its best efforts to obtain, at the reasonable
request of the Buyer, an order or other assurance that confidential treatment
will be accorded to such portion of the Confidential Information required to be
disclosed as the Buyer shall designate.

    (e)  NAME.  All necessary proceedings shall be taken by Target and Target's
Owners so as to cause the name of ACI Canada EFTS Limited to be changed to a
name which does not include "ACI".

    (f)  ACCESS TO BOOKS AND RECORDS.  For a period of seven (7) years
following the Closing Date (or until the expiration of the applicable statute of
limitations, giving effect to any waiver or extension thereof), the Buyer will
retain the books, records, documents, and other data relating to the Target in
existence at the Closing Date.  During such period and on reasonable notice, the
Buyer will afford to Tandem, its counsel and accountants and their


                                          32



agents, during normal business hours, reasonable access to such books, records,
documents and other data.  At the expense of Tandem, the Buyer will furnish
copies or if necessary the originals of any books, records, documents or other
data requested by Tandem.

    (g)  POST-CLOSING DOCUMENTATION.  The parties acknowledge that, by
agreement, all necessary assignments and third party consents will not have been
delivered as of the Closing of this Agreement.  Target agrees to use all
reasonable efforts to obtain and secure such assignments and consents as are
necessary to transfer to Buyer the Acquired Assets and to complete such
transfers as soon as reasonably possible.  In the event Target is unable to
obtain any required consents, Target shall take such actions as are reasonably
necessary to provide Buyer with the benefit of such contracts or agreements and
to be able to perform said contracts or agreements.

    9.   REMEDIES FOR BREACHES OF THIS AGREEMENT

    (a)  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All of the
representations and warranties of the Target contained in Section 3(a)-(d)(f)-
(i) and Section 3(k)-(z) of this Agreement shall survive the Closing (even if
the Buyer knew or had reason to know of any misrepresentation or breach of
warranty at the time of Closing) and continue in full force and effect for a
period of two (2) years thereafter. All of the other representations and
warranties of the Buyer contained in Section 4 and representations and
warranties of the Target, and the Target Owners and Tandem contained in Section
3(e)and Section 3(j) thereof shall survive the Closing (even if the damaged
Party knew or had reason to know of any misrepresentation or breach of warranty
at the time of Closing) and continue in full force and effect forever thereafter
(subject to any applicable statutes of limitations).

    (b)  INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE BUYER.

         (i)  Subject to the limitations set forth in Section 9(b)(iv) and (v)
    below, in the event any of the Target, Target Owners and/or Tandem breaches
    any of its representations, warranties, and covenants contained in the
    Agreement, and, if there is an applicable survival period pursuant to
    Section 9(a) above, provided that the Buyer makes a written claim for
    indemnification against any of the Target, Target Owners and/or Tandem
    pursuant to Section 10(g) below within such survival period, then Tandem
    agrees to indemnify the Buyer from and against the entirety of any Adverse
    Consequences the Buyer may suffer through and after the date of the claim
    for indemnification (including any Adverse Consequences the Buyer may
    suffer after the end of any applicable survival period) resulting from or
    caused by the breach (or the alleged breach).


                                          33



         (ii) Subject to the limitations set forth in Section 9(b)(iv) and (v)
    below, Tandem agrees to indemnify the Buyer from and against any Adverse
    Consequences the Buyer may suffer resulting from any Liability of the
    Target which is not an Assumed Liability (including any Liability of the
    Target that becomes a Liability of the Buyer under any bulk transfer law of
    any jurisdiction, under any common law doctrine of de facto merger or
    successor liability, or otherwise by operation of law).

         (iii) Subject to the limitations set forth in Section 9(b)(iv) and
    (v), in order to enable Tandem to mitigate the damages resulting from a
    claim or a likely claim of intellectual property infringement by any item,
    Tandem will be entitled to (i) procure the right for Buyer to continue
    using the item, (ii) modify the item to avoid the infringement, but without
    impairing the functionality or performance characteristics of the affected
    item, or (iii) replace the item with items of similar, commercially
    acceptable functionality and performance characteristics.  Further, Buyer
    shall have no right to indemnification for any claim alleging any ACI
    Product  infringes the intellectual property rights of a third party.

         (iv) Tandem shall have the total obligation to Buyer for claims under
    Section 9(b)(i), (ii) and (iii) that were caused by an event that occurred
    during the period January 1, 1994 to the date of Closing.  If the event
    causing the claim occurred prior to January 1, 1994, Buyer and Tandem shall
    cooperate with one another in the selection of counsel and the sharing of
    fees and costs of litigation, and agree to share equally the obligation for
    the damages incurred by Buyer.  In case of a claim from an event that
    occurred resulting in continuing damages, the obligation for said claim
    will be allocated between Tandem and Buyer beginning with the event and
    continuing during the term of its existence as set forth above in this
    subsection (iv).  If the event causing the claim occurs after the Closing,
    Tandem shall have no obligation to Buyer.  The foregoing limitation shall
    not apply to Tandem's obligations under paragraph 3(j) of this Agreement.

         (v)  Tandem shall not have any obligation to Buyer under Section
    9(b)(i), (ii) and (iii) until Buyer has incurred damages for claims that
    exceed $50,000 U.S. in the aggregate in which event Tandem shall be
    obligated for all damages claimed under this Section 9, but in no event
    shall Tandem's obligation hereunder exceed the sum of $2,500,000 U.S.  The
    foregoing limitation shall not apply to Tandem's obligations under
    paragraph 3(j) of this Agreement.

    (c)  INDEMNIFICATION PROVISIONS FOR BENEFIT OF TANDEM.


                                          34



         (i)  In the event the Buyer breaches (or in the event any third party
    alleges facts that, if true, would mean the Buyer has breached) any of its
    representations, warranties, and covenants contained in this Agreement,
    and, if there is an applicable survival period pursuant to Section 9(a)
    above, provided that Tandem makes a written claim for indemnification
    against the Buyer pursuant to Section 10(g) below within such survival
    period, then ACI agrees to indemnify Tandem from and against the entirety
    of any Adverse Consequences Tandem may suffer through and after the date of
    the claim for indemnification (including any Adverse Consequences Tandem
    may suffer after the end of any applicable survival period) resulting from,
    arising out of, relating to, in the nature of, or caused by the breach (or
    the alleged breach).

         (ii) ACI agrees to indemnify Tandem from and against the entirety of
    any Adverse Consequences Tandem may suffer resulting from, arising out of,
    relating to, in the nature of, or caused by any Assumed Liability for an
    event occurring subsequent to the date of Closing.

    (d)  MATTERS INVOLVING THIRD PARTIES.

         (i)  If any third party shall notify any Party (the "INDEMNIFIED
    PARTY") with respect to any matter (a "THIRD PARTY CLAIM") which may give
    rise to a claim for indemnification against any other Party (the
    "INDEMNIFYING PARTY") under this Section 9, then the Indemnified Party
    shall promptly (within the time period set forth in Section 9(a) above),
    notify each Indemnifying Party thereof in writing; PROVIDED, HOWEVER, that
    no delay on the part of the Indemnified Party in notifying any Indemnifying
    Party shall relieve the Indemnifying Party from any obligation hereunder
    unless (and then solely to the extent) the Indemnifying Party thereby is
    prejudiced.

         (ii) Any Indemnifying Party will have the right to defend the
    Indemnified Party against the Third Party Claim with counsel of its choice
    reasonably satisfactory to the Indemnified Party so long as (A) the
    Indemnifying Party notifies the Indemnified Party in writing within fifteen
    (15) days after the Indemnified Party has given notice of the Third Party
    Claim that the Indemnifying Party will indemnify the Indemnified Party from
    and against any Adverse Consequences the Indemnified Party may suffer
    resulting from the Third Party Claim, (B) the lndemnifying Party provides
    the Indemnified Party with evidence reasonably acceptable to the
    Indemnified Party that the Indemnifying Party will have the financial
    resources to defend against the Third Party Claim and fulfill its
    indemnification obligations hereunder, and (C) the Indemnifying Party
    conducts the defense of the Third Party Claim actively and diligently.


                                          35



         (iii) So long as the Indemnifying Party is conducting the defense
    of the Third Party Claim in accordance with Section 9(d)(ii) above, (A) the
    Indemnified Party may retain separate co-counsel at its sole cost and
    expense and participate in the defense of the Third Party Claim at any
    time, (B) the Indemnified Party will not consent to the entry of any
    judgment or enter into any settlement with respect to the Third Party Claim
    without the prior written consent of the Indemnifying Party (not to be
    withheld unreasonably), and (C) the Indemnifying Party will not consent to
    the entry of any judgment or enter into any settlement with respect to the
    Third Party Claim without the prior written consent of the Indemnified
    Party (not to be withheld unreasonably).

         (iv) In the event any of the conditions in Section 9(d)(ii) above is
    or becomes unsatisfied to the Indemnified Party, however, (A) the
    Indemnified Party may defend against, and consent to the entry of any
    judgment or enter into any settlement with respect to, the Third Party
    Claim in any manner it reasonably may deem appropriate (and the Indemnified
    Party need not consult with, or obtain any consent from, any Indemnifying
    Party in connection therewith), (B) the Indemnifying Parties will reimburse
    the Indemnified Party promptly and periodically for the costs of defending
    against the Third Party Claim (including reasonable attorneys' fees and
    expenses), and (C) the Indemnifying Parties will remain responsible for any
    Adverse Consequences the Indemnified Party may suffer resulting from,
    arising out of, relating to, in the nature of, or caused by the Third Party
    Claim to the fullest extent provided in this Section 9.

    (e)  DETERMINATION OF ADVERSE CONSEQUENCES.   If the Indemnifying Party
fails to honor its obligations under this paragraph 9, the Parties shall take
into account the time cost of money (using nine percent (9%) as the discount
rate) in determining Adverse Consequences for purposes of this Section 9.

    (f)  OTHER INDEMNIFICATION PROVISIONS.  Except for any equitable remedies
which may be available, the foregoing indemnification provisions are the sole
remedies available for any breach of a representation or warranty. Each of the
Target Owners hereby agrees that it will not make any claim for indemnification
against the Buyer by reason of the fact that he or it was a director, officer,
employee, or agent of the Target or was serving at the request of any such
entity as a partner, trustee, director, officer, employee, or agent of another
entity (whether such claim is for judgments, damages, penalties, fines, costs,
amounts paid in settlement, losses, expenses, or otherwise and whether such
claim is pursuant to any statute, charter document, bylaw, agreement, or
otherwise) with respect to any action, suit, proceeding, complaint, claim, or
demand brought by the Buyer against such Target Owners and Tandem (whether such
action, suit, proceeding, complaint, claim, or demand is pursuant to this
Agreement, applicable law, or otherwise).


                                          36



    10.  MISCELLANEOUS.

    (a)  PRESS RELEASES AND PUBLIC ANNOUNCEMENTS. No Party shall issue any
press release or make any public announcement relating to the subject matter of
this Agreement prior to the Closing without the prior written approval of the
other Party; PROVIDED, HOWEVER, that any Party may make any public disclosure it

forth.

    (h)  GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with and enforced in accordance with the laws of the Provence of
Ontario and the laws of Canada applicable thereto.

    (i)  AMENDMENTS AND WAIVERS. No amendment of any provision of this

Buyer and the Target. The Target may consent to any such amendment at any time
prior to the Closing with the prior authorization of its owner. No waiver by any
Party of any default, misrepresentation, or breach of warranty or covenant
hereunder, whether intentional or not, shall be deemed to extend to any prior or

hereunder or affect in any way any rights arising by virtue of any prior or
subsequent such occurrence.

    (j)  SEVERABILITY. Any term or provision of this Agreement that is invalid

validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

    (k)  EXPENSES.   Each of the Buyer, the Target, and the Target Owners will

favoring or disfavoring any Party by virtue of the authorship of any of the
provisions of this Agreement. Any reference to any federal, province, state,
local, or foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word


                                          39



"including" shall mean including without limitation. Nothing in the Disclosure
Schedule shall be deemed adequate to disclose an exception to a representation
or warranty made herein unless the Disclosure Schedule identifies the exception
with reasonable particularity and describes the relevant facts in reasonable
detail. Without limiting the generality of the foregoing, the mere listing (or
inclusion of a copy) of a document or other item shall not be deemed adequate to
disclose an exception to a representation or warranty made herein (unless the
representation or warranty has to do with the existence of the document or other
item itself). The Parties intend that each representation, warranty, and
covenant contained herein shall have independent significance. If any Party has
breached any representation, warranty, or covenant contained herein in any
respect, the fact that there exists another representation, warranty, or
covenant relating to the same subject matter (regardless of the relative levels
of specificity) which the Party has not breached shall not detract from or
mitigate the fact that the Party is in breach of the first representation,
warranty, or covenant.

    (m)  INCORPORATION OF EXHIBITS AND SCHEDULES. The Exhibits and Schedules
identified in this Agreement are incorporated herein by reference and made a
part hereof.

    (n)  SPECIFIC PERFORMANCE.  Each of the Parties acknowledges and agrees
that the other Party would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Party shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court having jurisdiction over the Parties and the matter, in addition to any
other remedy to which it may be entitled, at law or in equity.

    (o)  BULK TRANSFER LAWS.  The Buyer acknowledges that the Target will not
comply with the provisions of any bulk transfer laws of any jurisdiction in
connection with the transactions contemplated by this Agreement.
