ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

ASI ACQUISITION

     On July 9, 1997, the Registrant exercised its option under an Option
Agreement dated September 10, 1996 by and among the Registrant, Australian
Software Innovations (Services) Pty Ltd ("ASI"), Kilat Holdings Pty. Limited
("Kilat"), Eng Lee and Mary Lee (the "Option Agreement") and acquired
substantially all of the assets, and assumed certain liabilities, of ASI, a
software developer located in Sydney, Australia (the "ASI Acquisition").  The
principal ASI assets acquired by the Registrant consist of the OPEN AVIATOR
(SYSMON), CONTROL TOWER (LOGMAN) and FLIGHT LOG (ASI Accounting) software

products.  Except as otherwise indicated below, all dollar amounts indicate
United States Dollars.  In connection with the ASI Acquisition, the Registrant
undertook the following actions:

     (a)  The Registrant, ASI, Kilat and Eng and Mary Lee entered into an Asset
          Purchase Agreement, pursuant to which the Registrant and Centerpost
          Innovations Pty. Ltd., a wholly-owned subsidiary of the Registrant
          ("Centerpost"), will pay the aggregate amount of $750,000 to acquire
          all of the tangible assets and goodwill of ASI.  Of the total amount
          paid, $130,000 was paid previously pursuant to the terms of the Option
          Agreement, $170,000 was paid by the Registrant at closing, $100,000
          was paid by Centerpost at closing and $350,000 will be paid by the
          Registrant in seven monthly installments commencing on August 1, 1997.

     (b)  The Registrant, ASI, Kilat and Eng and Mary Lee entered into an
          Intellectual Property Purchase Agreement, pursuant to which the
          Registrant paid $455,000 to acquire all of the intellectual property
          and other intangible assets of ASI.

     (c)  The Registrant, ASI, Kilat and Eng and Mary Lee entered into a Deed of
          Restraint of Trade, pursuant to which the Registrant paid $78,000 in
          exchange for the covenants of ASI, Kilat and Eng and Mary Lee to
          refrain from engaging in any business or activity that is competitive
          with the Registrant's business for a period of three years from the
          closing date of the ASI Acquisition.

     (d)  Centerpost and ASI entered into a Services Agreement, pursuant to
          which ASI will provide transition and consulting services to
          Centerpost for a period of one year from the closing date of the ASI
          Acquisition, subject to annual renewals thereafter if neither party
          elects to terminate the agreement, in exchange for Centerpost's
          obligation to pay an annual consulting fee of 200,000 Australian
          Dollars, paid in equal monthly installments.

     (e)  The Registrant and Eng Lee entered into a Consulting Agreement,
          pursuant to which Mr. Lee, the founder and Managing Director of ASI,
          will provide to the Registrant consulting services for a period of
          five months from the closing date of the ASI Acquisition in exchange
          for a total payment in the amount $500,000, paid in five equal monthly
          installments of $100,000.

     (f)  The Registrant and ASI entered into a Consulting Agreement, pursuant
          to which ASI will provide to the Registrant consulting services for a
          period of three years from the closing date of the ASI Acquisition in
          exchange for an annual consulting fee of $50,000, paid quarterly.

Copies of each of the agreements described above and of a press release
announcing the consummation of the ASI Acquisition are attached to this Report
as Exhibits 1 through 6 and 8, respectively.

     The amounts paid by the Registrant in connection with the ASI Acquisition
were determined through negotiations between the Registrant and the other
parties to the ASI Acquisition, based upon the business, assets, liabilities,
operations and prospects of ASI.  Mr. Eng Lee is Vice President, Chief Technical
Officer and a director of the Registrant.  The ASI Acquisition was funded
through the registrant's working capital without additional borrowing.

     The principal ASI assets acquired by the Registrant in the ASI Acquisition,
consisting of the software products described above, will not be used in the
Registrant's business, but were subsequently sold to BMC Software Inc. and BMC
Software (Cayman) LDC in the transactions described below.  The remaining ASI
assets acquired in the ASI Acquisition, consisting principally of distributer
and customer lists, goodwill, computer hardware, office equipment and furniture
and several vehicles, will be used by the Registrant and Centerpost in
continuing their existing operations in Australia and Asia.

BMC TRANSACTION.

     On July 10, 1997, the Registrant completed an asset sale contemplated by an
Asset Purchase and Services Agreement among BMC Software, Inc. and BMC Software
(Cayman) LDC (collectively, "BMC"), certain principal stockholders of the
Registrant, ASI and Eng Lee (the "BMC Agreement"), pursuant to which the
Registrant sold to BMC the OPEN AVIATOR (SYSMON), CONTROL TOWER (LOGMAN) and
FLIGHT LOG software products acquired by the Registrant in the ASI Acquisition
described above (the "Products") and assigned to BMC all of the Registrant's
rights to distribute the Products in the United States as well as other rights
under certain domestic and international distribution and license agreements
relating to the Products.  In addition, BMC assumed certain liabilities and
obligations relating to the distribution and license agreements assigned to BMC
by the Registrant.  The BMC Agreement also obligates the Registrant to provide
certain transition and maintenance services for a period of six months following
the closing of the BMC transactions.  The total amount paid by BMC in exchange
for the Products, the Registrant's U.S. distribution rights, the Registrant's
rights under the assigned distribution and license agreements and the transition
and maintenance services to be provided by the Registrant was approximately
$7,000,000.  A copy of the BMC Agreement and a press release announcing the
consummation of the asset sale are attached to the Report as Exhibits 7 and 9,
respectively.

     The price paid by BMC in connection with the transactions contemplated by
the BMC Agreement was determined through arms-length negotiations between BMC
and the Registrant based upon the parties' perceived value of the Products and
related rights and services transferred pursuant to the terms of the BMC
Agreement.  There was no material relationship between BMC and the Registrant or
any of its affiliates, any officer or director of the Registrant or any
associate of any such officer or director.

     Pursuant to the terms of the BMC Agreement, six individual officers,
directors and/or shareholders of the Company agreed to indemnify and hold
harmless BMC with respect to certain representations and warranties set forth in
the BMC Agreement.  The Company has agreed to indemnify and hold harmless these
individuals for certain claims if they are asserted by BMC against such
individuals under the BMC Agreement.

own benefit or for any other Person's benefit; PROVIDED, HOWEVER, that Buyer,
Centerpost, Seller, Kilat or the Shareholders may disclose (A) Proprietary
Information which at the time of the disclosure is part of the public knowledge
and readily accessible to such third party, (B) Proprietary Information which is
required by law to be disclosed, and (C) Proprietary Information required to be
disclosed to BMC by the terms of the BMC Agreement.

          (b)  RETURN.  Buyer, Centerpost, Seller, Kilat and the Shareholders
agree that if the Acquisition is not consummated, each of them will return to
the other parties hereto any and all material containing or reflecting
Proprietary Information.

          (c)  REMEDIES.  Each of Buyer, Centerpost, Seller, Kilat and the
Shareholders acknowledges and agrees that any breach of the terms of this
SECTION 6.2 would result in irreparable injury and damage to the injured party
for which such party would have no adequate remedy at law; each of Buyer,
Centerpost, Seller, Kilat and the Shareholders therefore also acknowledges and
agrees that in the event of such breach or any threat of breach, the injured or
threatened party shall be entitled, in addition to any other remedies to which
such party may be entitled at law or in equity, to an immediate injunction and
restraining order to prevent such breach and/or threatened breach by the
breaching or threatening party and/or any and all persons and/or entities acting
for and/or with such breaching or threatening party, without having to provide a
bond or other security or to prove actual damages.

     6.3  OPERATION OF BUSINESS.  Except pursuant to or in connection with the
BMC Agreement, neither Seller, Kilat nor either of the Shareholders will engage
in any practice, take any action or enter into any transaction outside the
Ordinary Course of Business with respect to the Assets, the Intellectual
Property Assets or the operation of Seller's business from the date of this
Agreement until the Closing Date without the prior written consent of Buyer and
Centerpost.  Without in any manner limiting the foregoing, Seller, Kilat and the
Shareholders covenant and agree that during such period,

               (i)  The aggregate monthly remuneration (including, without
     limitation, all salary, distributions, dividends, bonuses, deferred
     compensation, automobile lease expense, superannuation payments and other
     payments) paid to or for the benefit of Kilat and the Shareholders and all
     Affiliates of Kilat and the Shareholders shall not exceed Sixteen Thousand
     Six Hundred Sixty Seven Australian Dollars (AUS $16,667), and

               (ii) Except as set forth in the Disclosure Schedules, Seller will
     not, and Kilat and the Shareholders will not permit Seller to, make any
     payment or incur any obligation with respect to any asset of any nature
     whatsoever that is used in whole or in part for the personal use or benefit
     of any shareholder, officer, director or employee of Seller or any
     Affiliate thereof.

Seller, Kilat and the Shareholders will use their best commercially reasonable
efforts to preserve the Assets, the Intellectual Property Assets and the
goodwill and value of Seller's business, to comply with all laws applicable to
the Assets, the Intellectual Property Assets and Seller's business and to
maintain good working relationships with lessors, licensors, suppliers,
customers and employees.  In addition, Seller will not sell or contract to sell
any interest in Seller or lease, license, transfer, pledge, mortgage,
hypothecate or otherwise dispose of any of the Assets or the Intellectual
Property Assets and Kilat and the Shareholders will not permit Seller to take
any such action, except as expressly required by the BMC Agreement.  Seller will
not, and Kilat and the Shareholders will not permit Seller to, do any act or
thing or suffer or permit any omission which would make any policy of insurance
of Seller written with respect to the Assets or the Intellectual Property Assets
void or voidable or do anything that would mean that any existing insurance
policy of Seller is not materially in full force and effect at all times prior
to the Closing Date.

     6.4  PUBLICITY.  The parties hereto agree, subject to the provisions of
SECTION 6.2, to advise and confer with each other, to the maximum extent
possible, regarding and prior to the issuance of any reports, statements,
releases, public announcements or similar publicity with respect to this
Agreement or the transactions contemplated hereby; PROVIDED, HOWEVER, that any
of the parties may make such announcements, give such notices and provide such
information to Governmental Authorities, employees, creditors, affiliates and
the public as its counsel may advise is legally required.

     6.5  EXCLUSIVITY.  From and after the date of this Agreement until the
Closing:

          (a)  Except for dealings with BMC pursuant to the express terms of the
BMC Agreement, neither Seller nor any of its officers, directors, stockholders
or agents (including, without limitation, Kilat and the Shareholders) shall
directly or indirectly:

               (i)  Enter into any transaction with any party other than Buyer
or Centerpost relative to any disposition of the Assets, the Intellectual
Property Assets or Seller's business or operations or any part thereof; or

               (ii) Solicit or encourage submission of inquiries, proposals or
offers from any other party relative to potential disposition of the Assets, the
Intellectual Property Assets or Seller's business or operations or any part
thereof; or

               (iii)     Provide further information to any party other than
Buyer or Centerpost relating to any possible disposition of the Assets, the
Intellectual Property Assets or Seller's business or operations or any part
thereof.

          (b)  Seller, Kilat and the Shareholders agree that if Seller, Kilat or
either of the Shareholders receives an offer or proposal (other than the BMC
Agreement) relating to the possible disposition of the Assets, the Intellectual
Property Assets or Seller's business or operations or any part thereof, Seller,
Kilat and the Shareholders will immediately notify Buyer of such offer or
proposal, the identity of the party making the offer or proposal and the

                                    ARTICLE 7
                         INDEMNIFICATION AND LIMITATION

     7.1  INDEMNIFICATION BY SELLER AND THE SHAREHOLDERS.  Subject to the
limitations set forth in SECTION 7.4, Seller, Kilat and each of the
Shareholders, jointly and severally, unconditionally, absolutely and irrevocably
agree to and shall defend, indemnify and hold harmless Buyer, Centerpost, and
each of the officers, directors, employees, counsel, successors, assigns, and
legal representatives of Buyer and Centerpost (Buyer, Centerpost and such
persons are collectively referred to as the "BUYER'S INDEMNIFIED PERSONS") from
and against, and shall reimburse Buyer's Indemnified Persons for, each and every
Loss paid, imposed on or incurred by Buyer's Indemnified Persons, directly or
indirectly, relating to, resulting from or arising out of any inaccuracy in any
representation or warranty of Seller, Kilat or the Shareholders under the Option
Agreement, the Transaction Agreements or the Exhibits thereto or any agreement,
certificate or document delivered by Seller, Kilat or the Shareholders pursuant
hereto in any respect, or any breach or nonfulfillment of any covenant,
agreement or other obligation of Seller, Kilat or the Shareholders under the
Option Agreement, the Transaction Agreements or the Exhibits thereto or any
agreement, certificate or document to be delivered by Seller, Kilat or the
Shareholders pursuant hereto (including, without limitation, Seller s obligation
to pay Taxes pursuant to SECTION 1.7).  With respect to matters not involving
Proceedings brought or asserted by third parties against Buyer's Indemnified
Persons, within thirty (30) days after notification from Buyer's Indemnified
Persons supported by reasonable documentation setting forth the nature of the
circumstances entitling Buyer's Indemnified Persons to indemnity hereunder,
Seller, Kilat and the Shareholders shall, at no cost or expense to Buyer's
Indemnified Persons, diligently commence resolution of such matters in a manner
reasonably acceptable to Buyer's Indemnified Persons and shall diligently and
timely prosecute such resolution to completion; PROVIDED, HOWEVER, with respect
to those valid claims that may be satisfied by payment of a liquidated sum of
money and which are not disputed reasonably and in good faith by Seller, Kilat
and the Shareholders, Seller, Kilat and the Shareholders shall promptly pay the
amount so claimed.  If litigation or any other Proceeding is commenced or
threatened, the provisions of SECTION 7.3 shall control over the immediately
preceding sentence.  Buyer and Centerpost shall be entitled to offset against
any amounts owed by Buyer or Centerpost, as the case may be, to Seller, Kilat or
the Shareholders under any Transaction Agreement any amounts owed by Seller,
Kilat or the Shareholders, respectively, to Buyer or Centerpost hereunder.

     7.2  INDEMNIFICATION BY BUYER AND CENTERPOST.  Each of Buyer and Centerpost
unconditionally, absolutely and irrevocably agrees to and shall defend,
indemnify and hold harmless Seller, Kilat, the Shareholders and the successors,
assigns, heirs and legal and personal representatives of Seller, Kilat and the
Shareholders (Seller, Kilat, the Shareholders and such persons are collectively
referred to as the "SELLER'S INDEMNIFIED PERSONS") from and against, and shall
reimburse Seller's Indemnified Persons for, each and every Loss paid, imposed on
or incurred by Seller's Indemnified Persons, directly or indirectly, relating
to, resulting from or arising out of any inaccuracy in any representation or
warranty of Buyer or Centerpost under the Option Agreement, the Transaction
Agreements or the Exhibits thereto or any agreement, certificate or other
document delivered or to be delivered by Buyer or Centerpost pursuant hereto in
any respect, or any breach or nonfulfillment of any covenant, agreement or other
obligation of Buyer or Centerpost under the Option Agreement, the Transaction
Agreements, the Exhibits thereto or any agreement, certificate or document to be
delivered by Buyer or Centerpost pursuant hereto.  With respect to matters not
involving Proceedings brought or asserted by third parties against Seller's
Indemnified Persons, within thirty (30) days after notification from Seller's
Indemnified Persons supported by reasonable documentation setting forth the
nature of the circumstances entitling Seller's Indemnified Persons to indemnity
hereunder, the Buyer or Centerpost, at no cost or expense to Seller's
Indemnified Persons, shall diligently commence resolution of such matters in a
manner reasonably acceptable to Seller's Indemnified Persons and shall
diligently and timely prosecute such resolution to completion; PROVIDED,
HOWEVER, with respect to those valid claims that may be satisfied by payment of
a liquidated sum of money and which are not disputed reasonably and in good
faith by Buyer or Centerpost, Buyer or Centerpost shall promptly pay the amount
so claimed.  If litigation or any other Proceeding is commenced or threatened,
the provisions of SECTION 7.3 shall control over the immediately preceding
sentence.

     7.3  NOTICE AND DEFENSE OF THIRD-PARTY CLAIMS.  If any Proceeding shall be
brought or asserted against a party entitled to indemnification pursuant to
SECTIONS 7.1 or 7.2, or any successor thereto (the "INDEMNIFIED PERSON") in
respect of which indemnity may be sought under this Article from an indemnifying
person or any successor thereto (the "INDEMNIFYING PERSON"), the Indemnified
Person shall give prompt written notice of such Proceeding to the Indemnifying
Person who shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to the Indemnified Person and the payment of all
expenses; provided, that any delay or failure to so notify the Indemnifying
Person shall relieve the Indemnifying Person of its obligations hereunder only
to the extent, if at all, that it is prejudiced by reason of such delay or
failure.  In no event shall any Indemnified Person be required to make any
expenditure or bring any cause of action to enforce the Indemnifying Person's
obligations and liability under and pursuant to the indemnification obligations
set forth in this Article.  In addition, actual or threatened action by a
Governmental Authority or other Person is not a condition or prerequisite to the
Indemnifying Person's obligations under this Article.  The Indemnified Person
shall have the right to employ separate counsel in any of the foregoing
Proceedings and to participate in the defense thereof, but the reasonable fees
and expenses of such counsel shall be at the expense of the Indemnified Person
unless the Indemnified Person shall in good faith determine that there exist
actual or potential conflicts of interest which make representation by the same
counsel inappropriate.  The Indemnified Person's right to participate in the
defense or response to any Proceeding should not be deemed to limit or otherwise
modify its rights and obligations under this Article.  In the event that the
Indemnifying Person, within fifteen (15) days after notice of any such
Proceeding, fails to assume the defense thereof, the Indemnified Person shall
have the right to undertake the defense, compromise or settlement of such
Proceeding for the account of the Indemnifying Person, subject to the right of
the Indemnifying Person to assume the defense of such Proceeding with counsel
reasonably satisfactory to the Indemnified Person at any time prior to the
settlement, compromise or final determination thereof.  If the Indemnifying
Person assumes the defense of any Proceeding, the Indemnified Person shall,
reasonably and in good faith, assist and cooperate in the defense thereof.
Anything in this Article to the contrary notwithstanding, the Indemnifying
Person shall not, without the Indemnified Person's prior written consent, settle
or compromise any Proceeding or consent to the entry of any judgment with
respect to any Proceeding for anything other than money damages paid by the
Indemnifying Person.  The Indemnifying Person may, without the Indemnified
Person's prior written consent, settle or compromise any such Proceeding or
consent to entry of any judgment with respect to any such Proceeding that
requires solely the payment of money damages by the Indemnifying Person and that
includes as an unconditional term thereof the release by the claimant or the
plaintiff of the Indemnified Person from all liability in respect of such
Proceeding.

     7.4  LIMITATION OF LIABILITY.  Notwithstanding the foregoing provisions of
this ARTICLE 7, each of Buyer and Centerpost agrees that the maximum monetary
amount for which the Shareholders shall be liable to Buyer's Indemnified Persons
in connection with the provisions of the Transaction Agreements, shall be
limited to the aggregate amount of One Million Eight Hundred Thousand Dollars
($1,800,000); PROVIDED, HOWEVER, that the foregoing limitation on the liability
of the Shareholders shall not apply to, and each of the Shareholders shall be
jointly and severally liable to Buyer's Indemnified Persons, and any of them,
for the aggregate amount of actual damages resulting from:

          (a)  any representation made by Seller, Kilat or either of the
Shareholders which any of Seller, Kilat or either of the Shareholders knows or
has reason to know is false or misleading at the Closing Date, or

          (b)  any fraudulent conduct of Seller, Kilat or either of the
Shareholders.

Furthermore, each of Seller, Kilat and the Shareholders acknowledges and agrees
that the foregoing limitation of liability shall not in any manner limit the
liability of Seller and Kilat for any reason whatsoever.

     7.5  GUARANTEE.

          (a)  Kilat and each of the Shareholders gives the indemnity set forth
in SECTION 7.1 and the guarantee set forth in this SECTION 7.5 in consideration
of the agreement of Buyer and Centerpost to enter into the Transaction
Agreements.  Kilat and each of the Shareholders acknowledges the receipt of
valuable consideration from Buyer and Centerpost for the agreement of Kilat and
the Shareholders to incur obligations and give rights under such indemnity and
guarantee.

          (b)  Kilat and each of the Shareholders unconditionally and
irrevocably guarantees to Buyer and Centerpost the due and punctual performance
and observance by Seller of its obligations under the Transaction Agreements
including, without limitation, any obligation to pay money.

          (c)  Kilat and each of the Shareholders waive any right it, he or she
have of first requiring Buyer or Centerpost to commence proceedings or enforce
any other right against Seller or any other person before claiming under such
indemnity and guarantee.

          (d)  This guarantee and the foregoing indemnity are continuing
security obligations and are not discharged by any one payment.  Such guarantee
and indemnity do not merge on completion.

          (e)  The liabilities of Kilat and each of the Shareholders under such
guarantee and indemnity are as a guarantor, indemnifier and principal debtor and
the rights of Buyer and Centerpost under such guarantee and indemnity are not
affect by anything which might otherwise affect them at law or in equity
including, but not limited, one or more of the following:

               (i)  Buyer or Centerpost granting time or other indulgence to,
     compounding or compromising with or releasing Seller, or any other
     guarantor;

               (ii) acquiescence, delay, acts, omissions or mistakes on the part
     of Buyer or Centerpost;

               (iii)     any novation of a right of Buyer or Centerpost;

               (iv) any variation of the Transaction Agreements, or any
     agreement entered into in performance thereof; or

               (v)  the invalidity or unenforceability of an obligation or
     liability of a person other than the relevant guarantor (being Kilat or one
     of the Shareholders).

          (f)  Kilat and each of the Shareholders may not, without the consent
of Buyer and/or Centerpost, as the case may be:

               (i)  raise a set-off or counterclaim available to it or Seller
     against Buyer or Centerpost in reduction of it's liability under such
     guarantee and indemnity;

               (ii) claim to be entitled by way of contribution, indemnity,
     subrogation, marshaling or otherwise to the benefit of any security or
     guarantee held by Buyer or Centerpost in connection with the Transaction
     Agreements; or

               (iii)     prove in competition with Buyer or Centerpost, if a
     liquidator, provisional liquidator, receiver, official manager or trustee
     in bankruptcy is appointed in respect of Seller or Seller is otherwise
     unable to pay its debts when they fall due, until all money payable to
     Buyer or Centerpost in connection with the Transaction Agreements is paid.

          (g)  If a claim that a payment or transfer to Buyer or Centerpost in
connection with the Transaction Agreements is void or voidable (including, but
not limited to, a claim under laws relating to liquidation, insolvency or
protection of creditors) is upheld, conceded or compromised, then Buyer or
Centerpost, as the case may be, is entitled immediately as against Kilat and
each Shareholder to the rights to which it would have been entitled under such
guarantee and indemnity if the payment or transfer had not occurred.

          (h)  Kilat and each of the Shareholders agree to pay or reimburse each
of Buyer and Centerpost on demand for its costs, charges and expenses in making,
enforcing and doing anything in connection with such guarantee and indemnity
including, without limitation, legal costs and expenses on a full indemnity
basis.  Any amounts paid to Buyer or Centerpost by Kilat or one of the
Shareholders must be applied first against payment of costs, charges and
expenses under this SECTION 7.5(H), then against other obligations under such
guarantee and indemnity.

          (i)  Kilat and each of the Shareholders acknowledges having been given
a copy of this Agreement and having had full opportunity to consider its
provisions before entering into such guarantee and indemnity.

granting such waiver.  No waiver, or failure to insist upon strict compliance,
by any party of any condition or any breach of any obligation, term, covenant,

company organized under the laws of Australia, or order (the "LENDER"), at 51

holder hereof may designate in writing, in lawful money of the United States of
America, the principal sum of Three Hundred Fifty Thousand and no/100 United
States Dollars, according to the terms and conditions set forth in this Note.

     1.   Borrower shall make payments on the outstanding principal balance of
this Note in the monthly amounts of $50,000 each, commencing on August 8, 1997,
and continuing until February 8, 1998 (the "Maturity Date").  All indebtness
evidenced by this Note which remains outstanding on the Maturity Date shall be
due and payable in full thereon.

     2.   Borrower may prepay the principal amount of this Note, in whole or in
part, at any time without penalty or premium for any such early payment.

     3.   If any payment required by this Note is not made when due, or if any
other event occurs or circumstance exists which under any instrument evidencing
or securing the obligations evidenced by this Note entitles the holder hereof to
accelerate the maturity of such obligations, the entire unpaid principal balance
and accrued but unpaid interest hereunder shall, at the option of the holder
hereof, at once become due and payable without notice (time being the essence
hereof).  Failure to exercise such option shall not constitute a waiver of the
right to exercise the same in the event of any subsequent default, event or
circumstance giving rise to such right of acceleration.

     4.   Prior to the Maturity Date (or accelerated Maturity Date pursuant to
Section 3 above), no interest shall be due or payable by Borrower on amounts
outstanding hereunder.  All past due principal (whether by acceleration or in
due course) and, if permitted by applicable law, past due interest, shall, both
before and after judgment, bear interest at the rate of twenty percent (20%) per
annum.

     5.   Borrower agrees to pay the holder hereof a "late charge" equal to five
percent (5%) of any payment due pursuant to this Note which is more than fifteen
(15) days in arrears.

     6.   In the event that any payment under this Note is not made at the time
and in the manner required (whether before or after maturity), Borrower agrees
to pay, in addition to any late charge required by Section 5 above, any and all
costs and expenses (regardless of the particular nature thereof and whether
incurred before or after the initiation of suit or before or after judgment)
which may be incurred by the holder hereof in connection with the enforcement of
any of its rights under this Note, including, but not limited to, attorneys'
fees and all costs and expenses of collection.

     7.   Borrower and all sureties, guarantors and endorsers hereof waive
presentment for payment, demand and notice of dishonor and nonpayment of this
Note, and consent to any and all extensions of time, renewals, waivers, or
modifications that may be granted by the holder hereof with respect to the
payment or other provisions of this Note, and to the release of any security, or
any part thereof, with or without substitution.

     8.   Notwithstanding any other provision contained in this Note or in any
instrument given to evidence or secure the obligations evidenced hereby:  (i)
the rates of interest and charges provided for herein and therein shall in no
event exceed the rates and charges which result in interest being charged at a
rate equalling the maximum allowed by law; and (ii) if, for any reason
whatsoever, the holder hereof ever receives as interest in connection with the
transaction of which this Note is a part an amount which would result in
interest being charged at a rate exceeding the maximum allowed by law, such
amount or portion thereof as would otherwise be excessive interest shall
automatically be applied toward reduction of the unpaid principal balance then
outstanding hereunder and not toward payment of interest.

     9.   This Note is delivered in the State of Utah and shall be governed by
and construed in accordance with the laws of said State, without giving effect
to any conflict of laws provisions.  Each of Borrower and the Lender expressly
submits itself to the exclusive, personal jurisdiction of the federal and state
courts situated in Salt Lake City, Utah.  This Note shall bind the successors
and assigns of Borrower and shall inure to the successors and assigns of the
Lender.


          IN WITNESS WHEREOF, Borrower has executed this Note as of the day and
year first above written.

                       ADDITIONAL COVENANTS AND AGREEMENTS

     6.1  EXPENSES.  Except as otherwise expressly provided herein, each party
to this Agreement shall bear its respective expenses incurred in connection with
the preparation, execution and performance of the Transaction Agreements and the
transactions contemplated hereby, including without limitation all fees and
expenses of agents, business brokers, legal counsel, accountants, tax and
financial advisors and other facilitators and advisors.

     6.2  CONFIDENTIALITY.

          (a)  NON-DISCLOSURE AND USE.  Each of Buyer, Seller, Kilat and the
Shareholders acknowledges that, in connection with the transactions contemplated
by the Option Agreement and the Transaction Agreements, each has become or may
become privy to the technical, marketing and other proprietary information of
another party, including, without limitation, information, material, documents
and data related to such other party, to the business activities of such other
party and/or to its customers, trade secrets and other proprietary information
(collectively, the "PROPRIETARY INFORMATION").  Each agrees (i) to take at all
times all reasonably necessary steps to safeguard the confidentiality of any
Proprietary Information; (ii) not to disclose, reveal, make accessible or make
available to any third Person any Proprietary Information; and (iii) not to use
any Proprietary Information for such party's own benefit or for any other
Person's benefit; PROVIDED, HOWEVER, that Buyer, Seller, Kilat or the
Shareholders may disclose (A) Proprietary Information which at the time of the
disclosure is part of the public knowledge and readily accessible to such third
party, (B) Proprietary Information which is required by law to be disclosed, and
(C) Proprietary Information required to be disclosed to BMC by the terms of the
BMC Agreement.

          (b)  RETURN.  Buyer, Seller, Kilat and the Shareholders agree that if
the Acquisition is not consummated, each of them will return to the other
parties hereto any and all material containing or reflecting Proprietary
Information.

          (c)  REMEDIES.  Each of Buyer, Seller, Kilat and the Shareholders
acknowledges and agrees that any breach of the terms of this SECTION 6.2 would
result in irreparable injury and damage to the injured party for which such
party would have no adequate remedy at law; each of Buyer, Seller, Kilat and the
Shareholders therefore also acknowledges and agrees that in the event of such
breach or any threat of breach, the injured or threatened party shall be
entitled, in addition to any other remedies to which such party may be entitled
at law or in equity, to an immediate injunction and restraining order to prevent
such breach and/or threatened breach by the breaching or threatening party
and/or any and all persons and/or entities acting for and/or with such breaching
or threatening party, without having to provide a bond or other security or to
prove actual damages.

     6.3  OPERATION OF BUSINESS.  Except pursuant to or in connection with the
BMC Agreement, neither Seller, Kilat nor either of the Shareholders will engage
in any practice, take any action or enter into any transaction outside the
Ordinary Course of Business with respect to the Intellectual Property Assets or
the operation of Seller's business from the date of this Agreement until the
Closing Date without the prior written consent of Buyer.  Without in any manner
limiting the foregoing, Seller, Kilat and the Shareholders covenant and agree
that during such period,

               (i)  The aggregate monthly remuneration (including, without
     limitation, all salary, distributions, dividends, bonuses, deferred
     compensation, automobile lease expense, superannuation payments and other
     payments) paid to or for the benefit of Kilat and the Shareholders and all
     Affiliates of Kilat and the Shareholders shall not exceed Sixteen Thousand
     Six Hundred Sixty Seven Australian Dollars (AUS$16,667), and

               (ii) Except as set forth in the Disclosure Schedules, Seller will
     not, and Kilat and the Shareholders will not permit Seller to, make any
     payment or incur any obligation with respect to any asset of any nature
     whatsoever that is used in whole or in part for the personal use or benefit
     of any shareholder, officer, director or employee of Seller or any
     Affiliate thereof.

Seller, Kilat and the Shareholders will use their best commercially reasonable
efforts to preserve the Intellectual Property Assets and the goodwill and value
of Seller's business, to comply with all laws applicable to the Intellectual
Property Assets and Seller's business and to maintain good working relationships
with lessors, licensors, suppliers, customers and employees.  In addition,
Seller will not sell or contract to sell any interest in Seller or lease,
license, transfer, pledge, mortgage, hypothecate or otherwise dispose of any of
the Intellectual Property Assets and Kilat and the Shareholders will not permit
Seller to take any such action, except as expressly required by the BMC
Agreement.  Seller will not, and Kilat and the Shareholders will not permit
Seller to, do any act or thing or suffer or permit any omission which would make
any policy of insurance of Seller written with respect to the Intellectual
Property Assets void or voidable or do anything that would mean that any
existing insurance policy of Seller is not materially in full force and effect
at all times prior to the Closing Date.

     6.4  PUBLICITY.  The parties hereto agree, subject to the provisions of
SECTION 6.2, to advise and confer with each other, to the maximum extent
possible, regarding and prior to the issuance of any reports, statements,
releases, public announcements or similar publicity with respect to this
Agreement or the transactions contemplated hereby; PROVIDED, HOWEVER, that any
of the parties may make such announcements, give such notices and provide such
information to Governmental Authorities, employees, creditors, affiliates and
the public as its counsel may advise is legally required.

     6.5  EXCLUSIVITY.  From and after the date of this Agreement until the
Closing:

          (a)  Except for dealings with BMC pursuant to the express terms of the
BMC Agreement, neither Seller nor any of its officers, directors, stockholders
or agents (including, without limitation, Kilat and the Shareholders) shall
directly or indirectly:

               (i)  Enter into any transaction with any party other than Buyer
relative to any disposition of the Intellectual Property Assets or Seller's
business or operations or any part thereof; or

               (ii) Solicit or encourage submission of inquiries, proposals or
offers from any other party relative to potential disposition of the
Intellectual Property Assets or Seller's business or operations or any part
thereof; or

               (iii)     Provide further information to any party other than
Buyer relating to any possible disposition of the Intellectual Property Assets
or Seller's business or operations or any part thereof.

          (b)  Seller, Kilat and the Shareholders agree that if Seller, Kilat or
either of the Shareholders receives an offer or proposal (other than the BMC
Agreement) relating to the possible disposition of the Intellectual Property
Assets or Seller's business or operations or any part thereof, Seller, Kilat and
the Shareholders will immediately notify Buyer of such offer or proposal, the
identity of the party making the offer or proposal and the specific terms of the
offer or proposal.

     6.6  COOPERATION.  Kilat and each of the Shareholders agrees to cause
Seller to take, or to refrain from taking, all actions necessary to fulfill
Seller's covenants and obligations under the Transaction Agreements.


                                    ARTICLE 7
                         INDEMNIFICATION AND LIMITATION

     7.1  INDEMNIFICATION BY SELLER AND THE SHAREHOLDERS.  Subject to the
limitations set forth in SECTION 7.4, Seller, Kilat and each of the
Shareholders, jointly and severally, unconditionally, absolutely and irrevocably
agree to and shall defend, indemnify and hold harmless Buyer, and each of
Buyer's officers, directors, employees, counsel, successors, assigns, and legal
representatives (Buyer and such persons are collectively referred to as the
"BUYER'S INDEMNIFIED PERSONS") from and against, and shall reimburse Buyer's
Indemnified Persons for, each and every Loss paid, imposed on or incurred by
Buyer's Indemnified Persons, directly or indirectly, relating to, resulting from
or arising out of any inaccuracy in any representation or warranty of Seller,
Kilat or the Shareholders under the Option Agreement, the Transaction Agreements
or the Exhibits thereto or any agreement, certificate or document delivered by
Seller, Kilat or the Shareholders pursuant hereto in any respect, or any breach
or nonfulfillment of any covenant, agreement or other obligation of Seller,
Kilat or the Shareholders under the Option Agreement, the Transaction Agreements
or the Exhibits thereto or any agreement, certificate or document to be
delivered by Seller, Kilat or the Shareholders pursuant hereto.  With respect to
matters not involving Proceedings brought or asserted by third parties against
Buyer's Indemnified Persons, within thirty (30) days after notification from
Buyer's Indemnified Persons supported by reasonable documentation setting forth
the nature of the circumstances entitling Buyer's Indemnified Persons to
indemnity hereunder, Seller, Kilat and the Shareholders shall, at no cost or
expense to Buyer's Indemnified Persons, diligently commence resolution of such
matters in a manner reasonably acceptable to Buyer's Indemnified Persons and
shall diligently and timely prosecute such resolution to completion; PROVIDED,
HOWEVER, with respect to those valid claims that may be satisfied by payment of
a liquidated sum of money and which are not disputed reasonably and in good
faith by Seller, Kilat and the Shareholders, Seller, Kilat and the Shareholders
shall promptly pay the amount so claimed.  If litigation or any other Proceeding
is commenced or threatened, the provisions of SECTION 7.3 shall control over the
immediately preceding sentence.  Buyer shall be entitled to offset against any
amounts owed by Buyer to Seller, Kilat or the Shareholders under any Transaction
Agreement any amounts owed by Seller, Kilat or the Shareholders, respectively,
to Buyer hereunder.

     7.2  INDEMNIFICATION BY BUYER.  Buyer unconditionally, absolutely and
irrevocably agrees to and shall defend, indemnify and hold harmless Seller,
Kilat, the Shareholders and the successors, assigns, heirs and legal and
personal representatives of Seller, Kilat and the Shareholders (Seller, Kilat,
the Shareholders and such persons are collectively referred to as the "SELLER'S
INDEMNIFIED PERSONS") from and against, and shall reimburse Seller's Indemnified
Persons for, each and every Loss paid, imposed on or incurred by Seller's
Indemnified Persons, directly or indirectly, relating to, resulting from or
arising out of any inaccuracy in any representation or warranty of Buyer under
the Option Agreement, the Transaction Agreements or the Exhibits thereto or any
agreement, certificate or other document delivered or to be delivered by Buyer
pursuant hereto in any respect, or any breach or nonfulfillment of any covenant,
agreement or other obligation of Buyer under the Option Agreement, the
Transaction Agreements, the Exhibits thereto or any agreement, certificate or
document to be delivered by Buyer pursuant hereto.  With respect to matters not
involving Proceedings brought or asserted by third parties against Seller's
Indemnified Persons, within thirty (30) days after notification from Seller's
Indemnified Persons supported by reasonable documentation setting forth the
nature of the circumstances entitling Seller's Indemnified Persons to indemnity
hereunder, the Buyer, at no cost or expense to Seller's Indemnified Persons,
shall diligently commence resolution of such matters in a manner reasonably
acceptable to Seller's Indemnified Persons and shall diligently and timely
prosecute such resolution to completion; PROVIDED, HOWEVER, with respect to
those valid claims that may be satisfied by payment of a liquidated sum of money
and which are not disputed reasonably and in good faith by Buyer, Buyer shall
promptly pay the amount so claimed.  If litigation or any other Proceeding is
commenced or threatened, the provisions of SECTION 7.3 shall control over the
immediately preceding sentence.

     7.3  NOTICE AND DEFENSE OF THIRD-PARTY CLAIMS.  If any Proceeding shall be
brought or asserted against a party entitled to indemnification pursuant to
SECTIONS 7.1 or 7.2, or any successor thereto (the "INDEMNIFIED PERSON") in
respect of which indemnity may be sought under this Article from an indemnifying
person or any successor thereto (the "INDEMNIFYING PERSON"), the Indemnified
Person shall give prompt written notice of such Proceeding to the Indemnifying
Person who shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to the Indemnified Person and the payment of all
expenses; provided, that any delay or failure to so notify the Indemnifying
Person shall relieve the Indemnifying Person of its obligations hereunder only
to the extent, if at all, that it is prejudiced by reason of such delay or
failure.  In no event shall any Indemnified Person be required to make any
expenditure or bring any cause of action to enforce the Indemnifying Person's
obligations and liability under and pursuant to the indemnification obligations
set forth in this Article.  In addition, actual or threatened action by a
Governmental Authority or other Person is not a condition or prerequisite to the
Indemnifying Person's obligations under this Article.  The Indemnified Person
shall have the right to employ separate counsel in any of the foregoing
Proceedings and to participate in the defense thereof, but the reasonable fees
and expenses of such counsel shall be at the expense of the Indemnified Person
unless the Indemnified Person shall in good faith determine that there exist
actual or potential conflicts of interest which make representation by the same
counsel inappropriate.  The Indemnified Person's right to participate in the
defense or response to any Proceeding should not be deemed to limit or otherwise
modify its rights and obligations under this Article.  In the event that the
Indemnifying Person, within fifteen (15) days after notice of any such
Proceeding, fails to assume the defense thereof, the Indemnified Person shall
have the right to undertake the defense, compromise or settlement of such
Proceeding for the account of the Indemnifying Person, subject to the right of
the Indemnifying Person to assume the defense of such Proceeding with counsel
reasonably satisfactory to the Indemnified Person at any time prior to the
settlement, compromise or final determination thereof.  If the Indemnifying
Person assumes the defense of any Proceeding, the Indemnified Person shall,
reasonably and in good faith, assist and cooperate in the defense thereof.
Anything in this Article to the contrary notwithstanding, the Indemnifying
Person shall not, without the Indemnified Person's prior written consent, settle
or compromise any Proceeding or consent to the entry of any judgment with
respect to any Proceeding for anything other than money damages paid by the
Indemnifying Person.  The Indemnifying Person may, without the Indemnified
Person's prior written consent, settle or compromise any such Proceeding or
consent to entry of any judgment with respect to any such Proceeding that
requires solely the payment of money damages by the Indemnifying Person and that
includes as an unconditional term thereof the release by the claimant or the
plaintiff of the Indemnified Person from all liability in respect of such
Proceeding.

     7.4  LIMITATION OF LIABILITY.  Notwithstanding the foregoing provisions of
this ARTICLE 7, Buyer agrees that the maximum monetary amount for which the
Shareholders shall be liable to Buyer's Indemnified Persons in connection with
the provisions of the Transaction Agreements shall be limited to the aggregate
amount of One Million Eight Hundred Thousand Dollars ($1,800,000); PROVIDED,
HOWEVER, that the foregoing limitation on the liability of the Shareholders
shall not apply to, and each of the Shareholders shall be jointly and severally
liable to Buyer's Indemnified Persons, and any of them, for the aggregate amount
of actual damages resulting from:

          (a)  any representation made by Seller, Kilat or either of the
Shareholders which any of Seller, Kilat or either of the Shareholders knows or
has reason to know is false or misleading at the Closing Date, or

          (b)  any fraudulent conduct of Seller, Kilat or either of the
Shareholders.

Furthermore, each of Seller, Kilat and the Shareholders acknowledges and agrees
that the foregoing limitation of liability shall not in any manner limit the
liability of Seller and Kilat for any reason whatsoever.

     7.5  GUARANTEE.

          (a)  Kilat and each of the Shareholders gives the indemnity set forth
in SECTION 7.1 and the guarantee set forth in this SECTION 7.5 in consideration
of Buyer's agreement to enter into the Transaction Agreements.  Kilat and each
of the Shareholders acknowledges the receipt of valuable consideration from
Buyer for the agreement of Kilat and the Shareholders to incur obligations and
give rights under such indemnity and guarantee.

          (b)  Kilat and each of the Shareholders unconditionally and
irrevocably guarantees to Buyer the due and punctual performance and observance
by Seller of its obligations under the Transaction Agreements including, without
limitation, any obligation to pay money.

          (c)  Kilat and each of the Shareholders waive any right it, he or she
have of first requiring Buyer to commence proceedings or enforce any other right
against Seller or any other person before claiming under such indemnity and
guarantee.

          (d)  This guarantee and the foregoing indemnity are continuing
security obligations and are not discharged by any one payment.  Such guarantee
and indemnity do not merge on completion.

          (e)  The liabilities of Kilat and each of the Shareholders under such
guarantee and indemnity are as a guarantor, indemnifier and principal debtor and
the rights of Buyer under such guarantee and indemnity are not affect by
anything which might otherwise affect them at law or in equity including, but
not limited, one or more of the following:
               (i)  Buyer granting time or other indulgence to, compounding or
     compromising with or releasing Seller, or any other guarantor;

               (ii) acquiescence, delay, acts, omissions or mistakes on the part
     of Buyer;

               (iii)     any novation of a right of Buyer;

               (iv) any variation of the Transaction Agreements, or any
     agreement entered into in performance of thereof; or

               (v)  the invalidity or unenforceability of an obligation or
     liability of a person other than the relevant guarantor (being Kilat or one
     of the Shareholders).

          (f)  Kilat and each of the Shareholders may not, without the consent
of Buyer:

               (i)  raise a set-off or counterclaim available to it or Seller
     against Buyer in reduction of it's liability under such guarantee and
     indemnity;

               (ii) claim to be entitled by way of contribution, indemnity,
     subrogation, marshaling or otherwise to the benefit of any security or
     guarantee held by Buyer in connection with the Transaction Agreements; or

               (iii)     prove in competition with Buyer, if a liquidator,
     provisional liquidator, receiver, official manager or trustee in bankruptcy
     is appointed in respect of Seller or Seller is otherwise unable to pay its
     debts when they fall due,

     until all money payable to Buyer in connection with the Transaction
Agreements is paid.

          (g)  If a claim that a payment or transfer to Buyer in connection with
the Transaction Agreements is void or voidable (including, but not limited to, a
claim under laws relating to liquidation, insolvency or protection of creditors)
is upheld, conceded or compromised, then Buyer is entitled immediately as
against Kilat and each Shareholder to the rights to which it would have been
entitled under such guarantee and indemnity if the payment or transfer had not
occurred.

          (h)  Kilat and each of the Shareholders agree to pay or reimburse
Buyer on demand for its costs, charges and expenses in making, enforcing and
doing anything in connection with such guarantee and indemnity including,
without limitation, legal costs and expenses on a full indemnity basis.  Any
amounts paid to Buyer by Kilat or one of the Shareholders must be applied first
against payment of costs, charges and expenses under this SECTION 7.5(H), then
against other obligations under such guarantee and indemnity.

          (i)  Kilat and each of the Shareholders acknowledges having been given
a copy of this Agreement and having had full opportunity to consider its
provisions before entering into such guarantee and indemnity.


                                    ARTICLE 8

     8.1  SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS.
Notwithstanding any investigation made at any time by or on behalf of the
parties hereto, all of the representations and warranties of the parties shall
survive the Closing of the transactions contemplated by the Transaction

of the covenants of the parties shall survive the Closing, including but not
limited to the obligations of the parties set forth in SECTION 6.2 and the

granting such waiver.  No waiver, or failure to insist upon strict compliance,
by any party of any condition or any breach of any obligation, term, covenant,
representation, warranty or agreement contained in this Agreement, in any one or
more instances, shall be construed to be a waiver of, or estoppel with respect

term, covenant, representation, warranty or agreement.  Whenever this Agreement
requires or permits consent by or on behalf of any party hereto, such consent
shall be given in writing in a manner consistent with the requirements for a

     Purchase and Services Agreement dated June 30, 1997 among BMC Software,
     Inc., BMC Software (Cayman) LDC, Buyer, ASI and Lee.

          (b)  If any of the prohibitions or restrictions contained in this Deed
     is judged by any court to go beyond what is reasonable in the
     circumstances, but would be reasonable and necessary if any activity were
     deleted or a period or area were reduced, then the prohibitions or
     restrictions will apply with that activity deleted or period or area
     reduced by the minimum amount determined necessary by the relevant court.

          (c)  Each of the prohibitions and restrictions in this Deed has effect
     as a separate and several prohibition or restriction and is to be enforced
     accordingly.

          (d)  Notwithstanding any of the other provisions of this Deed, Seller,
     Kilat, the Shareholders and their respective Affiliates may hold in the
     aggregate up to, but not more than, ten percent (10%) of the capital stock
     of a public company, the shares of which are quoted on the Australian Stock
     Exchange Limited, even though that company carried on any of the activities
     referred to in this clause.

          (e)  Seller, Kilat and the Shareholders each acknowledge that all the
     prohibitions and restrictions contained in this Deed are reasonable in
     these circumstances and warrant that:

               (i)  they have received independent legal advice with respect to
          this Deed;

               (ii) they consider such prohibitions and restrictions to go no
          further than reasonably necessary to protect the goodwill associated
          with the Assets; and

               (iii)     damages would not be an adequate remedy to protect the
          goodwill associated with the Assets.

          (f)  For purposes of this Deed, the term  Affiliate  shall mean, with
     respect to any specified person or entity, each other person or entity
     which, directly or indirectly, controls, is controlled by or is under
     common control with such specified person or entity (whether a general or
     limited partner), each officer, director or general partner of such
     specified entity, and each other person or entity who is the beneficial
     owner of five percent (5%) or more of any class of the voting securities of
     such specified entity or five percent (5%) or more in market value of the
     outstanding securities of such entity.  For purposes of this definition,
     "control" means the possession of the power to direct or cause the
     direction of all or any part of the management and policies of a specified
     person or entity, whether through the ownership of voting securities, by
     contract or otherwise.

          (g)  For purposes of this Deed, the term "engaged or involved in"


     includes direct or indirect involvement as a principal, agent, partner,
     employee, shareholder, member, unitholder, director, trustee, beneficiary,
     manager, consultant, adviser or financier.

hereby acknowledged, Centerpost and ASI agree as follows:

     1.   SERVICES.  ASI hereby agrees that, during the Term (as defined below),
it shall make available to Centerpost the services of Eng H. Lee ("Lee"), the
current managing director of ASI.  Centerpost hereby engages ASI for the Term to
make such services available and engages Lee for the Term, as an independent
contractor to Centerpost, to perform the duties pertaining to the office of
managing director of Centerpost.

     2.   TERM.  The term of this Agreement (the "Term") shall commence on the
date of this Agreement and continue through and expire on the first anniversary
thereof, unless earlier terminated as permitted herein.  The Term shall be
automatically renewed for successive additional periods of one year, unless the

ASI provides written notice to the other party hereto of its desire not to renew
at least ninety days in advance of the end of the then-current Term.

     3.   CONSIDERATION.  As consideration for the services to be provided by
ASI and Lee, Centerpost shall pay to ASI the annual sum of Two Hundred Thousand
Australian Dollars per year, payable in monthly installments.  ASI and Lee shall
be responsible for the payment of any taxes or other assessments on such
consideration.

     4.   TERMINATION.  Either party may terminate this Agreement for cause
provided that the complaining party shall provide at least fifteen (15) days'

known, the extent of the breach and the action required to correct the breach.
The breaching party shall be afforded fifteen (15) days (or such additional time
as the complaining party may determine, as confirmed in writing, to be
reasonable) to cure the breach or, as determined by the complaining party, to
achieve substantial cure if a complete cure cannot be reasonably effectuated
within the designated period.  If the breach remains uncured at the expiration

terms hereof, all notices and demands required or permitted under this Agreement
shall be in writing and shall be deemed to have been given or delivered:

titles set forth in the text of this Agreement are for guidance only and shall
have no significance in the interpretation of this Agreement.  When this
Agreement refers to a Section by number or letter without further
identification, the reference shall be construed as pertaining to the
corresponding Section of this Agreement unless the context clearly requires
reference to another instrument, agreement or document.

agreement between the parties with respect to the specific subject matter
hereof, and this Agreement supersedes all prior agreements and understandings

modification of any of the terms of this Agreement or cancellation or
replacement of this Agreement shall not be valid unless in writing and signed by
the parties.

          (d)  WAIVER OF BREACH.  The waiver by Centerpost of any breach of any
provision of this Agreement by ASI shall not operate or be construed as a waiver
of any subsequent breach by ASI.

provision herein contained is held to be invalid or void by any court of
competent jurisdiction, the same shall be deemed severable from the remainder of

herein, the rights and remedies of the parties hereto shall not be mutually
exclusive, and the exercise of one or more of the provisions of this Agreement
shall not preclude the exercise of any other rights or remedies provided for by
this Agreement or by law, equity, statute or otherwise.  Each of the parties
confirms that damages at law may be an inadequate remedy for a breach or
threatened breach of any of the provisions hereof.

          (g)  GOVERNING LAW.  This Agreement shall be governed by and construed
under the laws of New South Wales, Australia, without reference to its choice of
law provisions.

                                                            Salt Lake City, Utah


     FOR VALUE RECEIVED, Eng H. Lee, an individual (the "BORROWER"), promises
and agrees to pay to the order of Sento Technical Innovations Corporation, a
Utah corporation, or order (the "LENDER"), at 311 North State Street, Orem, Utah
84057, or at such other place as the holder hereof may designate in writing, in
lawful money of the United States of America, the principal sum of Five Hundred
Thousand and no/100 Unites States Dollars, according to the terms and conditions
set forth in this Note.

     1.   Borrower shall make payments on the outstanding principal balance of
this Note in the monthly amounts of $100,000 each, commencing on August ___,
1997, and continuing until December ___, 1997 (the "Maturity Date").
Notwithstanding the foregoing, Lender agrees that during the term of a
Consulting Agreement entered into by and between Lender and Borrower as of July






___, 1997 (the "CONSULTING AGREEMENT"), the obligation of Borrower to make
payments required under this Note shall be offset against the obligation of
Lender to pay to Borrower the monthly consulting payments required pursuant to
the terms of the Consulting Agreement.  All indebtness evidenced by this Note
which remains outstanding on the Maturity Date shall be due and payable in full
thereon.

     2.   Borrower may prepay the principal amount of this Note, in whole or in
part, at any time without penalty or premium for any such early payment.

     3.   If any payment required by this Note is not made when due, or if any
other event occurs or circumstance exists which under any instrument evidencing
or securing the obligations evidenced by this Note entitles the holder hereof to
accelerate the maturity of such obligations, the entire unpaid principal balance
and accrued but unpaid interest hereunder shall, at the option of the holder
hereof, at once become due and payable without notice (time being the essence
hereof).  Failure to exercise such option shall not constitute a waiver of the
right to exercise the same in the event of any subsequent default, event or
circumstance giving rise to such right of acceleration.

     4.   Prior to the Maturity Date, no interest shall be due or payable by
Borrower on amounts outstanding hereunder.  All past due principal (whether by
acceleration or in due course) and, if permitted by applicable law, past due
interest, shall, both before and after judgment, bear interest at the rate of
twenty percent (20%) per annum.

     5.   Borrower agrees to pay the holder hereof a "late charge" equal to five
percent (5%) of any payment due pursuant to this Note which is more than fifteen
(15) days in arrears.

     6.   In the event that any payment under this Note is not made at the time
and in the manner required (whether before or after maturity), Borrower agrees
to pay, in addition to any late charge required by Section 5 above, any and all
costs and expenses (regardless of the particular nature thereof and whether
incurred before or after the initiation of suit or before or after judgment)
which may be incurred by the holder hereof in connection with the enforcement of
any of its rights under this Note, including, but not limited to, attorneys'
fees and all costs and expenses of collection.

     7.   Borrower and all sureties, guarantors and endorsers hereof waive
presentment for payment, demand and notice of dishonor and nonpayment of this
Note, and consent to any and all extensions of time, renewals, waivers, or
modifications that may be granted by the holder hereof with respect to the
payment or other provisions of this Note, and to the release of any security, or
any part thereof, with or without substitution.

     Closing, Seller will sell, convey, assign, transfer and deliver the
     following:  (i) all right, title and interest in and to the Products, the

     Accounts Receivable and all other Assets, subject to the exceptions listed
     in sub-paragraph (b) of this Section 2.01, to BMC Cayman, and (ii) all
     right, title and interest in and to the distribution rights to the Products

          (b)  Such sale, conveyance, assignment, transfer and delivery will be
     effected, at the Closing by delivery by Seller to Buyers of the duly
     executed Assignment, Bill of Sale and such other good and sufficient

     Agreements; (ii) all rights under the Licenses; (iii) all rights under the
     Sub-Licenses and (iv) the exceptions set forth on Schedule 2.01(b).

          (c)  At the Closing, Buyers shall assume the liabilities and
     obligations arising from the acts and omissions of Buyers under the
     Assignable Distribution Agreements and Assignable Licenses after the
     Closing (the  Assumed Obligations ), by delivery to Seller of the duly

     obligations being assumed by Buyers at the Closing, provided; however,
     that: in the event any Retained Distribution Agreements or Retained
     Licenses are assigned to Buyers subsequent to the Closing, all obligations
     of the Seller under any such Retained Distribution Agreements or Retained
     Licenses shall thereafter be considered  Assumed Obligations  for purposes
     of this Section 2.01.  Except as specifically set forth in the preceding
     sentences, Buyers shall neither assume nor agree to pay, perform or
     discharge, and Seller shall solely retain and be responsible for paying and
     discharging, all liabilities and obligations occurring or arising under
     Licenses and Distribution Agreements prior to the Closing and all other
     liabilities and obligations of Seller, whether disclosed, undisclosed,
     direct, indirect, absolute, contingent, secured, unsecured, accrued or
     otherwise.  Except as specifically set forth in this paragraph, Seller
     shall solely retain and be responsible for paying, discharging and
     performing all liabilities or obligations of any nature of Seller

     on or prior to the Closing or that arise out of, or result from, any act or
     omission or alleged act or omission of Seller or its employees or agents or
     subcontractors, on or prior to the Closing.  The liabilities and
     obligations not being assumed by Buyers are hereinafter collectively called
     the  Excluded Obligations.   Seller shall utilize all reasonable efforts
     that may be necessary to prevent any person, firm or governmental authority
     from having recourse against any of the Assets or against Buyers as
     transferee thereof, with respect to the Excluded Obligations at the
     Closing.  For the avoidance of doubt, any sales or other transfer tax
     arising out of the sale of the Assets to Buyers shall be the sole
     responsibility of Seller, and Seller shall indemnify and hold Buyers
     harmless from and against any liability arising from or relating to any
     claim of non-payment or underpayment of the same.

     2.02.     CONSIDERATION.  Subject to the terms and conditions of this
Agreement, in reliance on Seller s, Seller Stockholders , Optionee s and Lee s
representations, warranties and agreements contained herein, and in
consideration of the aforesaid sale, conveyance, assignment, transfer and
delivery of the Assets, Buyers will deliver or cause to be delivered to Seller
at the Closing, as payment for the aforesaid sale, conveyance, assignment,
transfer and delivery of the Assets, the following consideration:

     United States and of an amount equal to $4,550,000 to be paid by BMC Cayman
     for all remaining Assets (together, the  Purchase Price ), which shall be
     payable as follows: $5,600,000 (the  Closing Payment ) to Seller or as
     directed by Seller and $1,400,000 to the Escrow Account.

Agreement will take place at 10:00 a.m. local time at BMC, 2101 CityWest

changed to such other place as Buyers and Seller may mutually agree upon in
writing.  The date on which the closing actually occurs is hereinafter referred
to as the  Closing Date.   The closing shall be effective as of the close of
business on the Closing Date (the closing, when so effective, the  Closing ).

the consideration payable to BMC is allocable to this noncompetition covenant.

Buyers, the benefits thereunder, including, but not limited to, the economic
benefits accruing post-Closing to the licensor under the Retained Distribution
Agreements or Retained Licenses and the enforcement of the benefit of Buyers or

thereunder.

maintenance and support services plan set forth in Schedule 9.05 for a period of
six months following the Closing Date; provided, however, that Buyers may, upon
giving written notice to Seller, reduce such six-month period to any shorter
period selected by Buyers .  Buyers shall make appropriate arrangements to
provide timely access to the Source Code of the Products as necessary to
performance by Seller, Optionee and Lee of their obligations under this
Agreement.  Seller, Optionee and Lee covenant that the services they will
provide pursuant to this Section 9.05 will conform in all material respects to
the descriptions and specifications therefor set forth in Schedule 9.05.

faith. Buyers will pay to Seller, in consideration of Seller, Optionee and Lee s
performance of these services, 100% of any maintenance fees received by Buyers
during the period in which Seller, Optionee and Lee are providing these
services.  Buyers will invoice, bill and collect fees in connection with all
maintenance services after the Closing Date.

     9.06 INTEGRATION OF PRODUCTS.  Seller or Optionee shall provide three of
the leading developers of the Products, the names of whom are set forth on

PATROL systems management software product as set forth on Schedule 9.06.
Buyers shall have the option of extending such services for an additional six
months at the cost of $50,000 per month with the understanding that if Buyers
elect to extend such services for the additional six months, Buyers shall pay a
completion bonus of $15,000 per individual to each of the three developers
listed on Schedule 9.06.  Seller and Optionee covenant that the services they
will provide pursuant to this Section 9.06 will conform in all respects to the
descriptions and specifications therefor set forth in Schedule 9.06.  Seller and

Section 9.06 in a professional manner with due diligence and good faith.  In the

Act ( Controlling Persons ) in respect of any and all claims, losses, damages,
liabilities, demands, assessments, judgments, costs and expenses (including,

(collectively,  Damages ) reasonably incurred by Buyers, any of their directors,

following:

          (i)  any misrepresentation or breach of any warranty made by the
     Indemnifying Parties in this Agreement or in any schedule, exhibit,
     certificate or other instrument contemplated by this Agreement; and

          (ii) the breach of any covenant, agreement or obligation of the
     Indemnifying Parties contained in this Agreement or any other instrument
     contemplated in this Agreement.

     In addition, each of Seller and Optionee, severally and not jointly, shall
indemnify, defend and hold harmless Buyers from and against all Damages
resulting from the following:

          (i)  its liabilities or obligations (whether absolute, accrued,
     contingent or otherwise) that are not Assumed Obligations as defined in
     Section 2.01(c);

          (ii) any taxes relating to its operations prior to the Closing Date;
     and

          (iii)     the noncompliance by it with the provisions of any
     applicable bulk sales, fraudulent conveyance or other similar law for the
     protection of its creditors.

     12.03     CLAIMS FOR INDEMNIFICATION.

          (a)  Whenever any claim shall arise for indemnification under this
     Article XII, the party asserting the claim for indemnification (the
      Indemnified Party ) shall promptly describe such claim in a written notice
     ( Notice of Claim ) to the party from which indemnification is sought (the
      Indemnifying Party ) and, when known, specify the facts constituting the
     basis for such claim and the amount or an estimate of the amount of such
     claim.  Each Notice of Claim shall (A) be signed by a proper representative
     of the Indemnified Party, (B) contain a description of the claim,
     (C) specify the amount of such claim, and (D) state that, in the opinion of
     the signer thereof, such Notice of Claim is valid under the terms of this
     Article XII and is being given by the Indemnified Party in good faith.

               (i)  Without limiting the foregoing, the Indemnified Party shall
          give the Indemnifying Party prompt notice of any claim for
          indemnification hereunder resulting from, or in connection with, any
          claim or legal proceeding by a person who is not a party to this
          Agreement ( Third Party Claim ) and, with respect to any Third Party
          Claim, the Indemnifying Party shall at its election, undertake and
          control the defense thereof by representatives reasonably satisfactory
          to the Indemnified Party and the Indemnifying Party.  However, the
          Indemnified Party shall have the right to participate in any such
          defense of a Third Party Claim with advisory counsel of its own
          choosing at its own expense.  In the event the Indemnifying Party,
          within a reasonable time after notice of any Third Party Claim, fails
          to defend, the Indemnified Party shall have the right diligently to
          undertake the defense, compromise or settlement of such Third Party
          Claim on behalf of, and for the account of, the Indemnifying Party, at
          the expense and risk of the Indemnifying Party to the extent of its
          liability set forth in Article XII.  The Indemnified Party, without
          the Indemnifying Party s written consent, shall not settle or
          compromise any such Third Party Claim or consent to entry of any
          judgment; the Indemnifying Party s consent shall be conditioned, among
          other matters, on the giving by the claimant or the plaintiff to the
          Indemnified Party, an unconditional release from all liability in
          respect of such Third Party Claim.  Notwithstanding any provision
          herein to the contrary, failure of the Indemnified Party to give any
          notice of any Third Party Claim required by this Article XII shall not
          constitute a waiver of the Indemnified Party s right to
          indemnification or a defense to any claim by the Indemnified Party
          hereunder unless the Indemnifying Party is materially adversely
          affected by such failure.

               (ii) the Indemnifying Party, without the Indemnified Party s
          written consent, shall not settle or compromise any Third Party Claim
          against the Indemnifying Party or consent to the entry of any judgment
          that does not include as an unconditional term thereof, the giving by
          the claimant or the plaintiff to the Indemnifying Party an
          unconditional release from all liability with respect to such Third
          Party Claim.

     12.04     EXTENT AND MANNER OF INDEMNIFICATION.  Seller shall have no
indemnification obligation under this Agreement with respect to any Damages that
exceed in the aggregate the total consideration received by Seller pursuant to
this Agreement.  Seller Stockholders, Optionee and Lee, collectively, shall have
no indemnification obligation under this Agreement with respect to any Damages
that exceed in the aggregate $3.5 million, such obligation to be allocated among
the Seller Stockholders, Optionee and Lee as set forth on SCHEDULE 12.04.  All
indemnification hereunder shall be effected first by the release of funds from
Escrow Account and, for claims in excess of the Escrow Amount, by payment of
cash or delivery of a certified cashier s check in the amount of the
indemnification liability.  Buyers agree to use commercially reasonable efforts
to pursue each of  Seller, Optionee and Lee for satisfaction of any
indemnification claims hereunder before approaching the Seller Stockholders.

     12.05     EXCLUSIVE REMEDY.  Subsequent to Closing, the provisions of this
Article XII shall provide the exclusive monetary, but not injunctive, remedy of
Buyers for any breach of this Agreement.

     12.06     ESCROW.

          (a)  Buyers and Seller agree that the Escrow Amount shall be placed in
     escrow with Buyers at Texas Commerce Bank, National Association, for a
     period beginning on the Closing and ending on the 24-month anniversary of
     the Closing, to be disbursed solely upon the joint signatures of the Buyers
     and Seller, all as set forth below, provided that one-half of the Escrow
     Amount shall be disbursed to Seller automatically on the 12-month
     anniversary of the Closing.  Disbursements from the Escrow Amount shall be
     made for the payment of amounts, if any, needed to satisfy the
     indemnification rights of the Buyers pursuant to Article XII hereof.

          (b)  The Escrow Amount or the appropriate portion thereof shall be
     disbursed to Buyers during the period ending on the 24-month anniversary of
     the Closing at any time or from time to time, upon the Buyers, giving
     Seller a Notice of Claim unless Seller delivers a Notice of Objection (as
     hereafter defined) in accordance with the procedures described in this
     Section 12.06.  Such Notice of Claim must be for a specified amount.

          (i)  Seller may give the Buyers written notice ( Notice of Objection )
     (A) attaching a copy of such Notice of Claim, (B) stating that, in the good
     faith opinion of the Seller, the claim described in such Notice of Claim is
     invalid (either in whole or in specified part) under the terms of Article
     XII hereof, (C) giving the reasons for the alleged invalidity, and (D)
     stating that, based on such alleged invalidity, the Seller objects to the
     payment of any portion of the Escrow Amount to the requesting party on
     account thereof.  In the event that a Notice of Objection alleges that a
     Notice of Claim is only partially invalid, the Seller, within 30 days of
     the receipt of such Notice of Claim, may agree to pay over to the Buyers
     that portion of the amounts specified in such Notice of Claim as to which
     no objection is made.  The Seller is not required to agree to make any
     payments to Buyers in respect of a Notice of Claim that has been objected
     to in a Notice of Objection given to Buyers as aforesaid except (X) as
     provided in the immediately preceding sentence, or (Y) in accordance with
     an order of any arbitration panel initiated by any of the parties hereto
     pursuant to paragraph ii below.

          (ii) Buyers and Seller agree to submit to final and binding
     arbitration any and all disputes Seller has specified in a Notice of
     Objection or Buyers have specified in a Notice of Claim to which the Seller
     has not responded within 30 days of receipt of such Notice of Claim.  Any
     such dispute subject to arbitration in accordance with the American
     Arbitration Association rules.

          (c)  The Escrow Account shall be terminated on the 24-month
     anniversary of the Closing Date; PROVIDED, HOWEVER, that the Escrow Account
     may continue beyond such 24-month anniversary, if Buyers have asserted
     indemnification claims, and any such claims remain unsatisfied (but only to
     the extent necessary to satisfy such unsatisfied claims).  Upon termination
     of the Escrow Account, all remaining amounts therein that constitute the
     Escrow Amount and that have not been paid or are not properly payable to
     third parties, or to Buyers pursuant hereto, shall be disbursed to Seller
     along with all interest that has accrued on the Escrow Amount during the
     period ending 24 months after the Closing.

PRESS RELEASE
For Immediate Release


BMC Software Strengthens PATROL  Operating System Management Through Acquisition
      of Performance Optimization Products From Sento Technical Innovations

   BMC SOFTWARE CURRENTLY INTEGRATING OPENAVIATOR INTO PATROL MANAGEMENT SUITE

HOUSTON    July 17, 1997   BMC Software  Inc. (NASDAQ: BMCS) and Sento Technical
Innovations Corporation (NASDAQ:SNTO) today announced BMC Software's acquisition
of  Sento's OpenAviator product suite, effective June  30, 1997.  The $7 million
acquisition included  rights under existing license  and distribution agreements
related  to  the OpenAviator  (also  known  as SYSMON)  suite,  as  well as  the
acquisition of two other software products - Control Tower and  FlightLog.  With
the  acquisition  of  OpenAviator, BMC  Software's  PATROL  Management  Suite of
products  now   will  monitor and  interpret  operating system  performance data
extracted  directly from the system's kernel -  the part of the operating system
that performs the system's most basic functions.  BMC Software also will acquire
an installed base of  several hundred OpenAviator customers concentrated  in the
Asia Pacific and European regions.
     "When  we  evaluated  the  OpenAviator  product  suite,  we  saw  a  unique
opportunity to enhance our  PATROL Knowledge Modules (KMs) for  Unix and Windows
NT," said Wayne Morris, director of corporate strategy for BMC  Software.  "With
the  integration  of OpenAviator,  PATROL will  enable  users to  conduct online
monitoring,  long-term  data  trending,  automated event  detection  and  action
execution - while  minimizing the use  of valuable CPU  capacity.  In  addition,
this acquisition will strengthen  our presence and  market share in the  rapidly
growing Asia Pacific region."
     BMC Software and  Sento are currently  integrating the OpenAviator  product
suite  into  BMC  Software's  PATROL  Unix  and NT  KMs.    The  integration  of
OpenAviator  will improve the performance and functional depth of BMC Software's
core operating system products.  Product support and maintenance for the current
OpenAviator customer base will  be transitioned to BMC Software  during the next
six months.
     "Recognizing the unique capabilities and value  of this product, we set out
to find the best company to appropriately integrate and market it worldwide.  In
the  end, we felt  that the perfect  match for OpenAviator  was BMC, and  we are
pleased  to participate  in a  concerted  effort to  integrate the  product into
PATROL," said Gary Godfrey, Sento chairman  and CEO.  "Additionally, the sale of
the OpenAviator product suite allows us to pursue other activities to facilitate
our  corporate  goals,  including  product  development,  acquisitions  and  the
expansion of our services resources."

     OpenAviator Provides Vital Data On Operating Systems
     OpenAviator is  a system availability  and analysis utility  which provides
system administrators with  the ability  to immediately access  and analyze  the
events  that  affect  the availability  of  computing  resources.   The  product
centrally  monitors Unix  and  Windows NT  operating  systems, enabling  on-line
resource  monitoring,  background  trend   analysis,  capacity  planning,  alarm
management, SNMP trap capabilities and user-defined data collection.  <PAGE>
     By integrating the kernel  reader capabilities of OpenAviator into  PATROL,
BMC Software's operating system  KMs can collect parameter information  from the
operating system in a more efficient manner.  The enhanced  operating system KMs
will enable users to view a "snapshot" of their entire system and view graphical
displays of  data  from multiple  systems  on one  screen.   Users  can  quickly
identify  which applications  and processes  are consuming  the majority  of the
system resources.

     Availability and Pricing
     The PATROL Management Suite, including the PATROL Operating Systems KMs, is
currently available from BMC Software and its agents and distributors worldwide.
PATROL  product pricing  begins at  $6,000 (U.S.),  depending on  the  number of
consoles and managed objects.   Pricing for individual PATROL  Knowledge Modules
begins at $750 (U.S.), depending on the quantity and server size.
