                    AGREEMENT OF PURCHASE AND SALE OF ASSETS

         THIS AGREEMENT OF PURCHASE AND SALE OF ASSETS (the "Agreement") is made
effective as of February 29, 1996 by and between STRATEGIC ADVANTAGE SOFTWARE

a corporation organized under the laws of England and Wales ("Cypher") and
SLATERSHELFCO 173 LIMITED, a corporation organized under the laws of England and
Wales ("Slatershelfco") (collectively, the "Seller").

                               W I T N E S S E T H

         WHEREAS, Seller is engaged in the business of developing, marketing and
distributing a variety of financial and accounting software products; and

         WHEREAS, Seller desires to divest certain assets, operations and
business associated with its Distribution Software Division (the "Business"),
including without limitation the distribution software product originally
developed by the Business (the "Distribution Product"); and

         WHEREAS, subject to the terms and conditions of this Agreement, Buyer
desires to purchase and Seller desires to sell and transfer to Buyer, the
Distribution Product and certain assets related to the Business as described
herein.

         NOW, THEREFORE, in consideration of the terms, covenants, and
conditions hereinafter set forth, the parties hereto hereby agree as follows:

                  1.        Purchase and Sale of Assets.

                  1.1       Purchased Assets.  Subject to the terms and 
conditions of this Agreement, Seller hereby agrees to sell, convey, assign,
transfer, set over and deliver to Buyer, and Buyer agrees to purchase and accept
from Seller certain of the assets of Seller related to the Business, whether
tangible, intangible, real, personal or mixed, and wherever located (hereinafter
sometimes collectively referred to as the "Purchased Assets"), which are more
particularly described as set forth below and in the schedules to this
Agreement. The Purchased Assets shall be free and clear of all liens,
encumbrances, liabilities, obligations, claims, security interests or rights of
third parties except as otherwise specifically provided herein and shall consist
of the following:

                             (a)      exclusive title and all rights to the 
intellectual property relating to the Distribution Product, including all source
code, object code, work-in-progress and developments with respect thereto;

                             (b)      trade names, trademarks, service marks and
copyrights (including registrations, licenses and applications pertaining
thereto) identified on Schedule 1.1(b) hereto, together with all goodwill
associated therewith (the "Trademarks and Copyrights") (jointly, with the items
described in (a) above, the "Intellectual Property Rights");
   2
                             (c)      all remaining equipment, Sybase license, 
other licensed software and other tangible assets as specified in Schedule
1.1(c) (collectively, the "Tangible Assets"); and 

                             (d)      all marketing data, promotional materials,
artwork and supplies listed on Schedule 1.1(d) (collectively, the "Miscellaneous
Assets").

                   2.        Purchase Price and Payment of Purchase Price.

                   2.1       Purchase Price; Payment.  As consideration for the 
sale and transfer of the Purchased Assets (exclusive of the Tangible Assets
specified on Schedule 1.1(c)) to Buyer, Buyer shall pay to Cypher the sum of One
Million Five Hundred Thousand United States Dollars (US$1,500,000) (the
"Purchase Price"). In payment of the Purchase Price, Buyer shall deliver to
Cypher at the Physical Closing two promissory notes in aggregate principal
amount of US$1,500,000 (the "Royalty Payment"). The Royalty Payment shall be due
and payable from time to time pursuant to Section 2.2 below and shall be
evidenced by promissory notes (collectively the "Royalty Notes"),one of which
shall be substantially in the form attached hereto as Exhibit A-1 ("Royalty
Note-No. 1") and the other of which shall be substantially in the form attached
hereto as Exhibit A-2 ("Royalty Note-No. 2"). The obligation of Buyer under the
Royalty Notes shall be secured by a security interest on all of the assets of
Buyer as set forth in the security agreement attached hereto as Exhibit B.

                    2.2       Payment of Royalties; Royalty Notes.

                              (a)      Buyer shall pay the principal amount due 
under the Royalty Note- No. 1 as set forth herein. Royalty Note-No.1 shall not
bear interest except in the event of default as specified therein. Buyer shall
pay to Cypher five percent (5%) of Buyer's Net Revenues (as defined below) from
the licensing of the Distribution Product (or future versions, updates,
improvements and enhancements, including versions using different databases)
from the date of Physical Closing until the earlier of the tenth (10th)
anniversary of the Physical Closing or such time as the aggregate amount paid
under this paragraph 2.2(a) shall equal One Million United States Dollars
(US$1,000,000). In the event that the aggregate payments under Royalty Note-No.
1 do not total US$1,000,000 as of the tenth (10th) anniversary of the Physical
Closing, the difference between US$1,000,000 and the total paid shall be due and
payable within sixty (60) days after the tenth (10th) anniversary date. If
necessary, Seller, in its sole discretion, may allow Buyer an extension of time
to pay such amount provided that such obligation shall be documented by a
promissory note on such terms and conditions as shall be reasonably agreed to by
the parties at the time specifically including, however, a term of Buyer's
choosing, but not more than three (3) years, and interest payable at the prime
rate as quoted by Platinum's primary bank plus two percent (2%).

                                 (b)      Additionally, Buyer shall pay the 
principal due under Royalty Note-No. 2 as set forth herein. Royalty Note-No. 2
shall not bear interest except in the event of default as specified therein.
Buyer shall pay to Cypher five percent (5%) of Buyer's Net Revenues from the
licensing of the Distribution Product from the tenth (10th) anniversary through
the twentieth (20th) anniversary of the Physical Closing. Payments under this
Royalty Note-No. 2 are to be made under this paragraph 2.2(b) until either the
aggregate amount of the royalties paid by Buyer to Cypher under this paragraph
equals Five Hundred Thousand Dollars (US$500,000) or until the twentieth (20th)
anniversary of the Physical Closing. In the event that the aggregate payments
under Royalty Note-No. 2 do not equal US$500,000 as of the twentieth (20th)
anniversary of the Physical Closing, any remaining principal balance shall be
excused and forgiven.

   3
                              (c)      Following the Closing, Buyer shall use 
its commercially reasonable efforts to sell, license or otherwise commercially
exploit the Distribution Product. Buyer agrees that such transactions entered
into by Buyer following the Closing will be in good faith and will not be
structured for the purpose of minimizing or avoiding the payment of royalties to
Seller hereunder.

                              (d)      "Net Revenues" shall mean, for any 
calendar month, all revenues from the licensing of the Distribution Product (and
future versions thereof, updates, improvements or enhancements, including
versions using different databases). Net revenues shall be net of shipping
costs, sales/use/VAT taxes, credits for returns, rebates and dealer or OEM
discounts allowed. In the event the Distribution Product is licensed by Buyer as
part of a larger software license, Net Revenues shall be allocated on the
relationship the license revenues specifically attributable to the Distribution
Product bear to the overall license revenues, and if such larger software
license includes unallocated product discounts or unallocated license fees, such
discounts and license fees shall be allocated on the relationship the suggested
retail price of the Distribution Product bears to the overall suggested retail
price of all licensed software, unless an alternative method of allocation shall
have been mutually agreed to. Under no circumstances will Buyer be required to
report for royalty purposes net sales in excess of the proceeds actually
received on such joint sales. Net Revenues shall be calculated each month and
royalties shall be payable to Seller on a quarterly basis as described below.

                              (e)      So long as Buyer is required to pay 
royalties hereunder, Buyer shall cause separate records to be maintained for the
licensing of the Distribution Product. The royalties shall be paid within thirty
(30) days following the end of each calendar quarter; provided, however, that
the first royalty payment under Royalty Note-No. 1 shall be due and payable
thirty (30) days after the six (6) month anniversary of the first license sale
of the Distribution Product (and future versions, updates, enhancements or
improvements, including versions using different databases), such payment shall
cover the entire period following the first license sale through the six (6)
month anniversary. Within thirty (30) days following the end of each calendar
quarter thereafter, Buyer shall deliver to Seller a written computation of Net
Revenues in accordance with this Section 2.2, which shall set forth the method
by which Net Revenues were computed and shall be certified as true and correct
in all material respects by the principal financial officer of Buyer. If Seller
does not agree with the determination of Net Revenues shown in Buyer's
computation, then Seller shall notify Buyer in writing within ten (10) days
after the receipt thereof, specifying with sufficient specificity the objections
thereto, and the parties shall in good faith attempt to reach agreement thereon.
If Buyer and Seller are unable to reach an agreement within thirty (30) days
after Seller's notice, the determination of the proper amount of Net Revenues
shall be submitted to an independent "big six" accounting firm, or such other
accounting firm mutually agreed to by Buyer and Seller. Seller and Buyer shall
split the costs of the accounting firm and if either party disagrees with the
determination of the independent accounting firm the matter shall be submitted
to arbitration in accordance with the arbitration provisions set forth in
Section 16.15 hereof; provided, however, that in the event that the amount of
Net Revenues determined by the independent accounting firm exceeds by ten
percent (10%) or more the amount of Net Revenues as calculated by Buyer, or is
at least ten percent (10%) less than the amount of Net Revenues calculated by
Seller, then the party whose calculation differs shall pay the full cost of the
accounting firm making such determination. At the end of each calendar quarter,
Buyer shall provide to Seller a forecast of revenues from the licensing of the
Distribution Product for the subsequent quarter.

                              (f)      The Royalty Notes shall not be assignable
by Buyer except: (i) in the event of full settlement by Buyer or its assignee of
the outstanding balance prior to or concurrent with such 



                                       3
   4
assignment; or (ii) with the prior written consent of Seller, which consent
shall not be unreasonably withheld. In determining whether to approve any
assignment request, Seller shall take into consideration the creditworthiness of
the proposed assignee, the nature of the business of the proposed assignee and
such other factors that a lender would ordinarily consider in a credit
determination.

                    2.3       Tangible Asset Payment.  As consideration for the
sale and transfer of the Tangible Assets described on Schedule 1.1(c) to Buyer,
Buyer shall pay to Cypher the net book value, as of February 29, 1996, thereof
(the "Tangible Assets Purchase Price"). In payment of the Tangible Assets
Purchase Price, Buyer shall deliver to Cypher a promissory note at the Tangible
Assets Closing (as defined below) in the principal amount of the Tangible Assets
Purchase Price in the form attached hereto as Exhibit C (the "Tangible Assets
Note"). The Tangible Assets Note shall bear eight percent (8%) simple interest
and shall be payable in sixty (60) equal consecutive monthly installments of
principal and accrued interest on the first day of each calendar month
commencing on the first day of the month following the six (6) month anniversary
of the Tangible Assets Closing. There shall be no prepayment penalty. The
obligation of the Buyer under the Tangible Assets Note shall be secured by a
security interest on all of the assets of Buyer as set forth in the security
agreement attached hereto as Exhibit B.

                    2.4       Allocation of Purchase Price.  The Purchase Price 
of the Purchased Assets shall be allocated as set forth on Schedule 2.4 attached
hereto. Buyer and Seller agree to execute any forms or notices required to
effect such allocation pursuant to the Internal Revenue Code of 1986, as amended
(the "Code"), including but not limited to Form 8594 under the Code.

                    2.5       Rights of Offset.  Each of Seller and Buyer shall 
have the right, in its reasonable discretion, to offset from time to time the
amount of any payment due to the other party against the reciprocal obligation
to receive any payment from such party which is past due and remains unpaid for
a period of sixty (60) days following receipt of written notice thereof.

                    2.6       Financing Contingency.  Should Buyer be unable to 
secure sufficient financing to allow it to generate royalty sales for the
Distribution Product (or future versions, updates, improvements and
enhancements, including versions using different databases) on or before June
30, 1998, then Buyer shall be required to return and convey title to the
Distribution Product, in its improved state. Thereafter, Buyer shall have no
further obligation under this Agreement.

         3.         Assumption Only of Specified Liabilities, Obligations, 
Contracts and Agreements.


                    3.1       No Assumption of Liabilities Unless Expressly 
Assumed. Buyer shall not assume nor have any duty or obligation with respect to
any liability, duty, obligation, contract, claim or agreement of any Seller.

                    3.2       Payment of Liabilities Not Assumed.  Each of 
Sellers shall indemnify, defend and hold Buyer harmless from, in accordance with
Section 13 below, all of the liabilities, duties, contracts, agreements, claims
and obligations of Seller.

                    3.3       Taxes.  Buyer shall not be responsible for any 
"Taxes" related to any period before the Closing Date (as hereinafter defined)
or the Tangible Assets Closing Date (as defined below) or arising from the
purchase of the Purchased Assets. "Taxes" for purposes of this Agreement 


                                       4
   5
means any federal, state, local, or foreign income, gross receipts, license,
payroll, employment, excise, severance, stamp, occupation, premium, windfall
profits, environmental (including taxed under Code Section59A), customs duties,
capital stock, franchise, profits, withholding, social security (or similar),
unemployment, disability, real property, personal property, sales, use,
transfer, registration, value added, alternative or add-on minimum, estimated,
or other tax of any kinds whatsoever, including any interest, penalty, or
addition thereto, whether disputed or not.

         4.         Closing.

                    4.1       Closing Date; Physical Closing.  Provided that all
conditions precedent set forth in this Agreement have been satisfied or waived,
the closing of the transactions contemplated hereby (the "Closing") shall occur
effective as of the close of business on February 29, 1996 (the "Closing Date").
The actual physical closing (the "Physical Closing") and the Closing deliveries
specified below shall occur as soon as practicable thereafter, but in no event
later than March 29, 1996, provided that all of the conditions set forth in this
Agreement have been satisfied or waived. The Physical Closing shall be held at
the offices of Seller, unless another place is mutually agreed upon by the
parties.

                    4.2       Tangible Assets Closing.  In regard to the 
Tangible Assets, Buyer and Seller shall mutually agree on the Tangible Assets
and Miscellaneous Assets to be purchased by Buyer and the Tangible Assets
Purchase Price. Upon such determination, Schedules 1.1(c) and 1.1(d) shall be
amended to reflect such items. The actual closing in regard to the Tangible
Assets (the "Tangible Assets Closing") shall occur as soon as practicable
following the Physical Closing, but in no event later than April 15, 1996 (the
"Tangible Assets Closing Date"). The Tangible Assets Closing shall be held at
the offices of Platinum, unless another place is mutually agreed upon by the
parties.

         5.         Representations and Warranties of Seller. As a material
inducement to Buyer to enter into this Agreement, Seller represents and warrants
the following, the truth and accuracy of each of which shall also constitute a
condition precedent to the obligations of Buyer hereunder:

                    5.1       Organization and Good Standing.  Each of Sellers 
is duly incorporated and, except for a delinquency in U.K. Companies House
filing, validly existing under the laws of the state or country of its
incorporation. Each of Sellers has full corporate power and authority to carry
on its business as it is now conducted. Each of Sellers is not in violation of
its charter documents in any manner which would adversely affect the validity,
binding nature or enforceability of its obligations under this Agreement or,
following the Physical Closing, Buyer's title to the Purchased Assets.

                    5.2       Authority.  Each of Sellers has all the necessary
corporate power and authority to enter into this Agreement and the other

performed by it hereunder and to consummate the transactions contemplated
hereby. The Transaction Documents have been duly authorized and approved by all
necessary action on the part of each of Sellers, as applicable. The Transaction
Documents have been duly executed and delivered by each of Sellers, as
applicable, and constitute valid and binding obligations of each of Sellers,
enforceable against each of Sellers in accordance with their respective terms,
subject as to enforceability to any applicable bankruptcy, insolvency,
moratorium or other laws affecting creditors' rights generally or such
principles of equity as a court of competent jurisdiction might apply.

                    5.3       Approvals.  No consent, approval or agreement of 
any person, entity, party, court or government is required to be obtained by

Assets, free and clear of restrictions or conditions to transfer or assignment,
and free and clear of all defects of title, mortgages, liens, encumbrances,
pledges, leases, licenses, equities, claims, charges, easements, rights of way,
covenants, conditions, conditional sale contracts, security interests and
restrictions, except for the lien of current taxes not yet due and payable which
shall remain the obligation of Sellers. Other than the warranties, conditions,
terms or representations specified in this Agreement and the related documents
delivered pursuant to this Agreement, Seller makes no express or implied
warranty, term, condition or representation regarding the Purchased Assets. THE
PURCHASED ASSETS, INCLUDING THE DISTRIBUTION PRODUCT AND THE SOURCE CODE
THEREOF, ARE BEING PURCHASED BY BUYER "AS IS" AND SELLER EXPRESSLY DISCLAIMS ALL
IMPLIED WARRANTIES, CONDITIONS, TERMS OR REPRESENTATIONS OF MERCHANTABILITY,
SATISFACTORY QUALITY OR FITNESS FOR A PARTICULAR PURPOSE.

                    5.5       No Conflict.  Neither the execution and delivery 
of, nor the consummation of the transactions contemplated by, this Agreement
will conflict with or result in the breach of the terms, conditions and
provisions of, or constitute a default (or an event that with notice or lapse of
time or both would become a default) under, or result in the creation of a lien
or encumbrance on any of the Purchased Assets pursuant to (A) the charter
documents of each of Sellers, (B) any agreement, document or instrument to which
any Seller is a party or by which any Seller is bound or (C) any judgment,
decree, order, statute, injunction, rule or regulation applicable to any Seller
or the Purchased Assets.

                    5.6       Litigation.  Except as set forth in Schedule 5.6

the transactions contemplated herein, whether at law or in equity, or before or
by any court or governmental agency, authority or body or before any arbitrator
of any kind, and (ii) to the best knowledge of each of Sellers, no
investigations are being conducted which could lead to any such action, suit or
proceeding.

                    5.7       Finder's Fees.  Seller has not incurred any 
liability to any broker, finder or agent for any brokerage fees, finder's fees
or commissions with respect to the transactions contemplated by this Agreement.

representations or warranties of Seller contained in this Agreement or the

furnished or to be furnished pursuant to this Agreement, contain, nor on the
date of the Physical Closing or Tangible Assets Closing will contain an untrue
statement of a material fact, or omit, nor on the date of the Physical Closing
or Tangible Assets Closing will omit to state a material fact necessary to make
the statements of fact herein or therein not misleading.

                    5.9       Trademarks, Patents, etc.

                              (a)      Schedule 1.1(b) contains a complete list 
of the Trademarks and Copyrights applicable to the Purchased Assets, including
any jurisdictions in which each right has been issued or registered or in which
any application for such issuance and/or registration has been filed. Seller
owns and possesses the Intellectual Property with no known or suspected
infringement of, or conflict with, the rights of others. Such ownership,
possession or license is exclusive, assignable and not subject to termination
without Seller's consent where the failure to be exclusive or not subject to
termination without Seller's consent would have a material adverse effect on the
rights of Seller, or Buyer upon transfer as provided herein, applicable to the
Purchased Assets. Seller is not aware of any third party that is infringing or
violating any of the Intellectual Property.

                              (b)      Seller is not aware of any unauthorized 
use, disclosure, infringement or misappropriation of any Intellectual Property
rights of Seller, any trade secret material to Seller related to the Business,
or any Intellectual Property right of any third party to the extent licensed by
or through Seller, by any third party, including any employee or former employee
of Seller. Seller has not entered into any agreement to indemnify any other
person against any charge of infringement of any Intellectual Property, other
than indemnification provisions contained in purchase orders and customer
licenses and support agreements arising in the ordinary course of business.

                              (c)      Seller is not, nor will it be, as a 
result of the execution and delivery of this Agreement or the performance of its
obligations under this Agreement, in breach of any license, sublicense or other
agreement relating to the Intellectual Property.

                              (d)      All registered trademarks held by Seller 
are valid and subsisting. Seller has no patents or registered copyrights with
respect to the Distribution Product. Seller (i) has not been sued in any suit,
action or proceeding which involves a claim of infringement of any patents,
trademarks, service marks, copyrights or violation of any trade secret or other
proprietary right of any third party with respect to the Distribution Product or
the Business and (ii) has not brought any action, suit or proceeding for
infringement of Intellectual Property or breach of any license or agreement
involving Intellectual Property with respect to the Distribution Product or the
Business against any third party. The manufacture, marketing, licensing or sales
of the Distribution Product does not infringe any patent, trademark, service
mark, copyright, trade secret or other proprietary right of any third party.

                              (e)      Seller believes that it has taken all 
reasonable and appropriate steps to protect and preserve the confidentiality of
all Intellectual Property not otherwise protected by patents or patent
applications or copyright.

                    5.10      Taxes.  Seller has no material liability for any 
Taxes with respect to the Purchased Assets, except for taxes which have accrued
and are not yet payable. Seller has not elected pursuant to the Code to be
treated as a Subchapter S corporation or a collapsible corporation pursuant to
Section 341(f) or Section 1362(a) of the Code.

                    5.11      Compliance with Laws.  Seller is not in violation 
of any law, ordinance, order, decree, rule or regulation of any governmental
agency, the violation of which could have a material adverse effect on the
Purchased Assets.

         6.         Representations and Warranties of Buyer. As a material
inducement to Seller to enter into this Agreement, Buyer represents and warrants
the following, the truth and accuracy of each of which shall also constitute a
condition precedent to the obligations of Seller hereunder:

                    6.1       Organization and Good Standing.  Buyer is duly 
organized, validly existing and in good standing under the laws of the State of
Wisconsin. Buyer was incorporated on February 29, 1996, and prior to the date
hereof had no business, operations, assets or liabilities, other than for
nominal capital received upon its initial capitalization and for the obligations
and liabilities related to this Agreement and the transactions contemplated
hereby.

                    6.2       Authority.  Buyer has all the necessary corporate 
power and authority to enter into this Agreement, and the other documents and
agreements contemplated to be entered into in connection herewith, and to
perform the obligations to be performed by it hereunder and thereunder and to
consummate the transactions contemplated hereby and thereby. This Agreement and
the other documents and agreements contemplated to be entered into in connection
herewith have been duly authorized and approved by all necessary action on the
part of the Board of Directors and shareholders of Buyer. This Agreement and the
other documents and agreements contemplated to be entered into in connection
herewith have been duly executed and delivered by Buyer and constitute valid and
binding obligations of Buyer, enforceable against Buyer in accordance with their
respective terms, subject as to enforceability to any applicable bankruptcy,
insolvency, moratorium or other laws affecting creditors' rights generally or
such principles of equity as a court of competent jurisdiction might apply.

                    6.3       Finder's Fees.  Buyer has not incurred any 
liability to any broker, finder or agent for any brokerage fees, finder's fees
or commissions with respect to the transactions contemplated by this Agreement.

                    6.4       Agreement Will Not Cause Breach.  Consummation of 
the transactions contemplated by this Agreement will not cause a default or an
event that, with notice or the lapse of time or both, would constitute a
default, breach or violation of Buyer's Certificate of Incorporation or Bylaws
or any agreement to which Buyer is a party or by which it or its property is
bound.

notice to the other party or parties (the "Indemnitors") of the nature and
amount of the Indemnity asserted promptly, and, in the case of any claim
relating to a third party action, as soon as reasonably practicable, but no less
than ten (10) days prior to the date a response or answer thereto is due, in
writing, thereof. The failure, refusal or neglect of such Indemnitee to notify
the Indemnitors within the time period specified above of any such claim or
action shall not relieve such Indemnitors from any liability which they may have
to such Indemnitee in connection therewith, unless the Indemnitors were
prejudiced by such a delay, and then only to the extent of the harm suffered by
such delay. In case any claim, demand or assessment shall be asserted or suit,
action or proceeding commenced against an Indemnitee and such Indemnitee shall
have notified the Indemnitor of the commencement thereof, the Indemnitor may, to
the extent that such claim, demand or assessment includes or may include
Indemnifiable Damages, assume the defense, conduct or settlement thereof, in
which event, Indemnitor shall be responsible for all Indemnifiable Damages which
may be suffered or incurred by the Indemnitee in connection therewith, as set
forth in Sections 13.1 and 13.2, and the defense thereof, with the assistance of
counsel selected by Indemnitor and approved by Indemnitee, which approval shall
not be unreasonably withheld. After notice from the Indemnitor to the Indemnitee
that it will so assume the defense thereof, the Indemnitors will not be liable
to the Indemnitee for expenses incurred in connection with the defense, conduct



                                       14
   15
or settlement thereof, except for such expenses as may be reasonably required to
enable the Indemnitors to take over such defense, conduct or settlement. The
Indemnitee will cooperate with the Indemnitors in connection with any such
claim, make personnel, witnesses, books and records relevant to the claim
available to the Indemnitors and grant such authorizations or powers of attorney
to the agents, representatives and counsel of the Indemnitors as the Indemnitors
may reasonably request in connection with the defense or settlement of any such
claim. In the event that the Indemnitors do not so assume the defense, conduct
or settlement of any claim, demand or assessment within thirty (30) days after
receiving notice of any claim relating to a third party action, claim, demand,
assertion or action as set forth above, the Indemnitee shall be entitled to
defend, conduct or settle such claim, demand or assessment without the written
consent of the Indemnitors and without relieving the Indemnitors from any of the
obligations, including reasonable attorney fees, to indemnify the Indemnitee
under Sections 13.1 or 13.2. The Indemnitee and the Indemnitors may agree in
writing, at any time, as to the existence and amount of an Indemnity, and, upon
the execution of such agreement, such Indemnity shall be deemed established.

                    13.4      Limitations.

                              (a)      Except with respect to claims (i) 
relating to covenants or agreements by either party, or (ii) based upon fraud,
neither party shall have any obligation to indemnify the other party under
Sections 13.1 or 13.2 above in respect to any Indemnifiable Damages unless the
aggregate cumulative total of all Indemnifiable Damages incurred by the
Indemnitee exceeds Ten Thousand United States Dollars (US$10,000), which amount
shall be deemed to be "material" as such term is used in the representations and
warranties of Seller and Buyer set forth in Sections 5 and 6 hereof,
respectively. In such event, the Indemnitees shall be entitled to
indemnification for the entire aggregate cumulative amount of such Indemnifiable
Damages. In no event shall the liability or obligation of Seller exceed the
Purchase Price. Notwithstanding the previous sentence, if a claim for
Indemnifiable Damages is brought by Buyer: (I) the out-of-pocket liability of
Sellers shall not exceed the greater of (i) $150,000 (plus Buyer's actual
reasonable attorneys fees) or (ii) that portion of the Purchase Price paid as of
the date a claim for Indemnifiable Damages is brought; and (II) Buyer shall have
the additional right to offset against the Purchase Price, payable under the
Royalty Note No. 1 and No. 2, the amount of the actual Indemnifiable Damages
incurred by Buyer, (less the amount recovered in clause (I) above), up to the
amount of the Purchase Price.

                              (b)      Further, notwithstanding anything to the 
contrary in this Section 13.4, Section 9 hereof or any other section of this
Agreement, (i) the limitations contained in the final sentence of Section
13.4(a) shall not apply to claims for Indemnifiable Damages relating to claims
of customers of Sellers arising from transactions prior to the Physical Closing;
and (ii) each of Platinum, Cypher and Slatershelfco, for a period of five (5)
years from the date of the Physical Closing, shall indemnify, defend and hold
harmless Buyer against and in respect of any Indemnifiable Damages that are the
direct result of a challenge to Buyer's title to the Purchased Assets, including
but not limited to, challenges to title based on claims that the present
transaction is a fraudulent conveyance or transfer by Seller or a preferential
transaction; provided, however, in no event shall the aggregate liability of
Platinum, Cypher and Slatershelfco exceed the Purchase Price.

                    13.5      Payment of Indemnity.  The Indemnitors shall pay 
the amount of each established Indemnity to the Indemnitee promptly, but not
more than thirty (30) days, after it has been properly established. Subject to
the limitations herein contained, the Indemnitee shall have all rights and
remedies available at law or equity for enforcement of its rights hereunder.

US $1,000,000                                              _______________, 1996


         FOR VALUE RECEIVED, STRATEGIC ADVANTAGE SOFTWARE CORPORATION, a
Wisconsin corporation with offices located at 1810 Thorstrand Road, Madison,
Wisconsin 53705 (the "Maker") promises to pay to the order of CYPHER BUSINESS
SYSTEMS, LTD., a corporation organized under the laws of England and Wales with
offices at c/o Platinum Software Corporation, 195 Technology Drive, Irvine,
California 92718 ("Cypher"), or such other place as the holder (the "Holder") of
this Secured Royalty Promissory Note-No. 1 (this "Note") may from time to time
in writing direct, the principal sum of One Million United States Dollars
(US$1,000,000), payable in full as set forth below. Except as provided below,
the principal amount of this Note shall not bear interest.

         This Note is the Royalty Note-No. 1 referred to in that certain
Agreement of Purchase and Sale of Assets, dated as of February 29, 1996, between
the Maker and Platinum Software Corporation, Cypher and Slatershelfco 173
Limited (the "Purchase Agreement") and is secured by a security interest created
under that certain Security Agreement of even date (the "Security Agreement")
between Maker and Cypher and Cypher is entitled to all of the benefits and
security of the collateral as set forth in the Security Agreement. Capitalized
terms used herein and not otherwise defined shall have the meanings assigned to
them in the Purchase Agreement.

         If any principal payable hereunder is not paid when due, or, in the
event of a default by Maker under the Purchase Agreement, the Security Agreement
or this Note, such overdue principal shall bear interest at a rate per annum
equal to ten percent (10%) from the due date until paid. Prepayment of principal
hereunder may be made at any time without penalty.

         All amounts due hereunder shall be payable in lawful money of the
United States of America. Maker shall pay to Cypher the principal amount of One
Million United States Dollars (US$1,000,000) as set forth herein. Maker shall
pay to Cypher five percent (5%) of Maker's Net Revenues from the licensing of
the Distribution Product until either (A) the aggregate amount of the royalties
paid by Maker to Cypher under Section 2 of the Purchase Agreement shall equal
US$1,000,000, or (B) the tenth (10th) anniversary of the date hereof, whichever
first occurs. In the event the tenth (10th) anniversary of the date hereof
occurs first and the aggregate royalties paid by Maker to Cypher under Section
2.2(a) of the Purchase Agreement does not total US$1,000,000, the difference
between US$1,000,000 and the aggregate royalties paid shall be paid in full by
Maker within sixty (60) days following such tenth (10th) anniversary of the date
hereof (the "Royalty Deficit Payment"); provided, however, Cypher in its sole
discretion, may allow Maker an extension of time to make the Royalty Deficit
Payment provided that such 
   25
obligation shall be documented by a promissory note on terms and conditions as
shall be reasonably agreed to by the parties at the time but specifically
including a term of Maker's choosing, but not more than three (3) years, and
interest payable at the prime rate quoted by Platinum's primary lender then in
effect plus two percent (2%). The royalties shall be payable within thirty (30)
days following the end of each calendar quarter in the manner set forth in the
Purchase Agreement; provided, however, that the first royalty payment shall be
due and payable thirty (30) days after the six (6) month anniversary of the
first license sale of the Distribution Product (and future versions, updates,
enhancements or improvements, including versions using different databases).
Such payment shall cover the entire period following the first license sale
through the six (6) month anniversary.

         In the event the Purchase Agreement shall terminate pursuant to Section
2.6 thereof, Maker shall have no further obligation under this Note.

         The principal amount of this Note and all accrued but unpaid interest
thereon, if any, shall become immediately due and payable, at the option of
Cypher, upon the occurrence of any of the following (an "Event of Default"):

         (a)    Any uncontested payment due under this Note shall have been in
default for at least thirty (30) days following the receipt of a written notice
of default in payment;

         (b)    The Maker shall fail or neglect to perform, keep or observe any
covenant or obligation of Maker as set forth in Sections 2.2, 15.1 and 15.3 of
the Purchase Agreement, which breach is not cured within thirty (30) days
following receipt by Maker of written notice thereof; or

         (c)    The Maker fails or neglects to comply with any covenant or
obligation of Maker set forth in the Security Agreement which breach is not
cured within the cure period provided in the Security Agreement;

         (d)    The Maker shall commence a voluntary case concerning itself 
under Title 11 of the United States Code entitled "Bankruptcy" as now or
hereafter in effect; or an involuntarily case shall be commenced against the
Maker and the petition shall not be controverted within thirty (30) days, or
shall not be dismissed within one hundred eighty (180) days after commencement
of the case; or a custodian shall be appointed for, or shall take charge of, all
or substantially all of the property of the Maker, or the Maker shall commence
any other proceeding under any reorganization, arrangement, adjustment of debt,
relief of debtors, dissolution, insolvency or liquidation or similar law of any
jurisdiction whether now or hereafter in effect relating to the Maker, or there
shall be commenced against the Maker any such proceeding, or the Maker shall be
adjudicated insolvent or bankrupt; or

         (e)    Greater than fifty percent (50%) of the voting capital stock of 
the Maker passes without the consent of Cypher to any person, firm or company
acting either individually or 


                                       2
   26
in concert, provided that transfers of shares between the registered
shareholders of Maker as of the date hereof will not be considered a change of
control. Notwithstanding the foregoing sentence, no consent of Cypher shall be
required for any transaction or series of transactions prior to June 30, 1998 in
which Maker secures capital or funding for business operations.

         The Maker hereby waives presentment for payment, protest and notice of
nonpayment and dishonor. If the Holder takes any action to collect this Note,
then the Maker shall be obligated to pay, in addition to all other amounts due
under this Note, all costs of collection and reasonable attorneys' fees and
other legal costs and expenses, provided that Maker is determined by a court of
competent jurisdiction to be liable for the amount sought to be collected.

         No delay or failure on the part of the Holder in the exercise of any
right or remedy hereunder shall operate as a waiver thereof, nor as an
acquiescence in any default, nor shall any single or partial exercise by the
Holder of any right or remedy preclude any other right or remedy. The Holder, at
its option, may enforce its rights against any collateral securing this Note
without enforcing its rights against the Maker or any other indebtedness due or
to become due to the Maker. The Maker agrees that, without releasing or
impairing the Maker's liability hereunder, the Holder may at any time release,
surrender, substitute or exchange any collateral securing this Note and may
release any party secondarily liable for the indebtedness evidenced by this
Note.

         This Note shall be governed by and construed in accordance with the
internal laws of the State of California of the United States. Cypher and Maker
each irrevocably agree that all actions arising directly or indirectly as a
result or in consequence of this Note shall be instituted and litigated only in
courts having situs in the State of California, and Cypher and Maker each hereby
consent to the exclusive jurisdiction and venue of any state or federal court
located and having its situs in the State of California.

         IN WITNESS WHEREOF, the Maker has caused this Note to be executed and
delivered on the day and year first above written.

         FOR VALUE RECEIVED, STRATEGIC ADVANTAGE SOFTWARE CORPORATION, a
Wisconsin corporation with offices located at 1810 Thorstrand Road, Madison,
Wisconsin 53705 (the "Maker") promises to pay to the order of CYPHER BUSINESS
SYSTEMS, LTD., a corporation organized under the laws of England and Wales with
offices at c/o Platinum Software Corporation, 195 Technology Drive, Irvine,
California 92718 ("Cypher"), or such other place as the holder (the "Holder") of
this Secured Royalty Promissory Note-No. 2 (this "Note") may from time to time
in writing direct, the principal sum of Five Hundred Thousand United States
Dollars (US$500,000), payable as set forth below. Except as provided below, the
principal amount of this Note shall not bear interest.

         This Note is the Royalty Note-No. 2 referred to in that certain
Agreement of Purchase and Sale of Assets, dated as of February 29, 1996, between
the Maker and Platinum Software Corporation, Cypher and Slatershelfco 173
Limited (the "Purchase Agreement") and is secured by a security interest created
under that certain Security Agreement of even date (the "Security Agreement")
between Maker and Cypher, and Cypher is entitled to all of the benefits and
security of the collateral as set forth in the Security Agreement. Capitalized
terms used herein and not otherwise defined shall have the meanings assigned to
them in the Purchase Agreement.

         In the event of a default by Maker under the Purchase Agreement, the
Security Agreement or this Note, the then-due, but unpaid principal shall bear
interest at a rate per annum equal to ten percent (10%). Prepayment of principal
hereunder may be made at any time without penalty.

         All amounts due hereunder shall be payable in lawful money of the
United States of America. Maker shall pay to Cypher the principal amount of Five
Hundred Thousand United States Dollars (US$500,000) as set forth herein. Maker
shall pay to Cypher five percent (5%) of Maker's Net Revenues from the licensing
of the Distribution Product from the day after the tenth (10th) anniversary of
the date hereof until either (A) the aggregate amount of the royalties paid by
Maker to Cypher under Section 2.2b of the Purchase Agreement shall equal
US$500,000, or (B) the twentieth (20th) anniversary of the date hereof,
whichever first occurs. In the event the twentieth (20th) anniversary of the
date hereof occurs first and the amount by which the aggregate royalties paid by
Maker to Cypher under Section 2.2(b) of the Purchase Agreement does not total
US$500,000, the difference between US$500,000 and the aggregate royalties paid
to date shall be excused and forgiven. The royalties shall be payable within
thirty (30) days following the end of each calendar quarter in the manner set
forth in the Purchase Agreement.
   28
         In the event the Purchase Agreement shall terminate pursuant to Section
2.6 thereof, Maker shall have not further obligation under this Note.

         The then-due, but unpaid principal amount of this Note and all accrued
but unpaid interest thereon, if any, shall become immediately due and payable,
at the option of Cypher, upon the occurrence of any of the following (an "Event
of Default"):

                    (a)       Any uncontested payment due under this Note shall 
have been in default for at least thirty (30) days following the receipt of a
written notice of default in payment;

                    (b)       The Maker shall fail or neglect to perform, keep 
or observe any covenant or obligation of Maker as set forth in Sections 2.2,
15.1 and 15.3 of the Purchase Agreement, which breach is not cured within thirty
(30) days following receipt by Maker of written notice thereof; or

                    (c)       The Maker fails or neglects to comply with any 
covenant or obligation of Maker set forth in the Security Agreement which breach
is not cured within the cure period provided in the Security Agreement;

                    (d)       The Maker shall commence a voluntary case 
concerning itself under Title 11 of the United States Code entitled "Bankruptcy"
as now or hereafter in effect; or an involuntarily case shall be commenced
against the Maker and the petition shall not be controverted within thirty (30)
days, or shall not be dismissed within one hundred eighty (180) days after
commencement of the case; or a custodian shall be appointed for, or shall take
charge of, all or substantially all of the property of the Maker, or the Maker
shall commence any other proceeding under any reorganization, arrangement,
adjustment of debt, relief of debtors, dissolution, insolvency or liquidation or
similar law of any jurisdiction whether now or hereafter in effect relating to
the Maker, or there shall be commenced against the Maker any such proceeding, or
the Maker shall be adjudicated insolvent or bankrupt; or

                    (e)       Greater than fifty-percent (50%) of the voting 
capital stock of the Maker passes without the consent of Cypher to any person,
firm or company acting either individually or in concert, provided that
transfers of shares between the registered shareholders of Maker as of the date
hereof will not be considered a change of control. Notwithstanding the foregoing
sentence, no consent of Cypher shall be required for any transaction or series
of transactions prior to June 30, 1998 in which Maker secures capital or funding
for business obligations.

         The Maker hereby waives presentment for payment, protest and notice of
nonpayment and dishonor. If the Holder takes any action to collect this Note,
then the Maker shall be obligated to pay, in addition to all other amounts due
under this Note, all costs of collection and reasonable attorneys' fees and
other legal costs and expenses provided that Maker is determined by a court of
competent jurisdiction to be liable for the amount sought to be collected.
 

                                      2
   29
         No delay or failure on the part of the Holder in the exercise of any
right or remedy hereunder shall operate as a waiver thereof, nor as an
acquiescence in any default, nor shall any single or partial exercise by the
Holder of any right or remedy preclude any other right or remedy. The Holder, at
its option, may enforce its rights against any collateral securing this Note
without enforcing its rights against the Maker or any other indebtedness due or
to become due to the Maker. The Maker agrees that, without releasing or
impairing the Maker's liability hereunder, the Holder may at any time release,
surrender, substitute or exchange any collateral securing this Note and may
release any party secondarily liable for the indebtedness evidenced by this
Note.

         This Note shall be governed by and construed in accordance with the
internal laws of the State of California of the United States. Cypher and Maker
each irrevocably agree that all actions arising directly or indirectly as a
result or in consequence of this Note shall be instituted and litigated only in
courts having situs in the State of California, and Cypher and Maker each hereby
consent to the exclusive jurisdiction and venue of any state or federal court
located and having its situs in the State of California.

         IN WITNESS WHEREOF, the Maker has caused this Note to be executed and
delivered on the day and year first above written.

                               SECURITY AGREEMENT

         THIS SECURITY AGREEMENT (the "Agreement"), is made as of __________,
1996, by and between STRATEGIC ADVANTAGE SOFTWARE CORPORATION, a Wisconsin
corporation (the "Debtor"), and CYPHER BUSINESS SYSTEMS, LTD, a company
registered under the laws of England and Wales (the "Secured Party"), with
reference to the following:

                                 R E C I T A L S

         A.     Debtor and Secured Party are parties to that certain Agreement 
of Purchase and Sale of Assets dated as of February 29, 1996 (the "Purchase
Agreement"), pursuant to which Debtor has agreed to purchase from Secured Party
and Secured Party has agreed to sell and transfer to Debtor certain assets,
operations and businesses of Secured Party, as described more particularly
therein (the "Purchased Assets").

         B.     Pursuant to the terms of the Purchase Agreement, Debtor is 
executing and delivering to Secured Party (i) a Secured Royalty Promissory
Note-No. 1 and (ii) a Secured Royalty Promissory Note-No. 2, each of even date
herewith in the original aggregate principal amount of One Million Five Hundred
Thousand United States Dollars (US$1,500,000) payable to the order of the
Secured Party (the "Notes") in connection with the purchase by Debtor of the
Purchased Assets.

         C.     Pursuant to the terms of the Purchase Agreement, Debtor is 
executing and delivering to Secured Party a Tangible Assets Promissory Note
dated as of the Tangible Assets Closing Date.

         D.     As a condition to the purchase of, and as part of the 
consideration for, the Purchased Assets, and in order to secure the payment and
performance of the obligations of Debtor to Secured Party under the Notes and
the Tangible Assets Promissory Note executed pursuant to the terms of the
Purchase Agreement, Debtor has agreed to grant to Secured Party a security
interest in the Collateral, as provided for herein.

         E.      Capitalized terms used herein and not otherwise defined shall 
have the meanings assigned to them in the Purchase Agreement.

         NOW, THEREFORE, in consideration of the foregoing recitals, the
following mutual agreements and promises, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:
   31
                                A G R E E M E N T

      1.      Security Interest.

              (a)     Creation of Security Interest. Debtor hereby grants to 
Secured Party a continuing security interest in all of Debtor's right, title and
interest in and to the Collateral, as defined in Subsection 1(b) below, in order
to secure the payment and performance of the obligations of Debtor to Secured
Party described in Subsection 1(c) below.

              (b)     Collateral. As used herein, the term "Collateral" shall 
mean all of the assets, properties and business of Debtor either tangible,
intangible, real, personal or mixed, whether now owned or hereafter acquired and
wherever located, together with all proceeds or products thereof including,
without limitation, all payments under insurance (whether or not the Secured
Party is the loss payee thereof), or any indemnity, warranty or guaranty (save
any obligation which is the responsibility of Secured Party, Platinum Software
Corporation or Slatershelfco 173 Limited), payable by reason of loss or damage
or otherwise with respect thereto.

              (c)     Obligations Secured. The security interest granted to 
Secured Party by Debtor pursuant to this Section 1 shall secure payment and
performance of Debtor's obligations under (i) the Notes; (ii) the Tangible
Assets Promissory Note; and (iii) any amendment, modification, renewal or
extension of the Notes or the Tangible Assets Promissory Note (collectively the
"Secured Obligations.").

              (d)     Subordination. Notwithstanding any other provision 
contained herein to the contrary, Secured Party undertakes with Debtor that if
so requested Secured Party will agree to subordinate its security interest
herein so that it ranks behind any security created in favor of Debtor's primary
lender providing capital for business operations to Debtor. Secured Party and
Debtor agree to use the standard form of subordination agreement provided by the
primary lender, provided the terms and conditions are reasonably acceptable to
Secured Party and Debtor, with such changes as either party may reasonably
request.

      2.      Representations and Warranties of Debtor.  Debtor hereby 
represents and warrants to Secured Party that:

              (a)     Debtor is a corporation duly organized, validly existing, 
and in good standing under the laws of the State of Wisconsin. Debtor was
incorporated on February 29, 1996, and prior to the date hereof Debtor had no
business, operations, assets or liabilities, other than for nominal capital
received upon its initial capitalization and for the obligations and liabilities
related to the Purchase Agreement and the transactions contemplated thereby.

              (b)    Debtor has all the necessary corporate power and authority 
to enter into this Agreement and to perform the obligations to be performed by
it hereunder and to consummate the transactions contemplated hereby. This
Agreement has been duly authorized and approved by all necessary action on the
part of the Board of Directors and stockholders of 
   32
Debtor. This Agreement has been duly executed and delivered by Debtor and
constitutes the valid and binding obligation of Debtor, enforceable against
Debtor in accordance with its terms, subject as to enforceability to any
applicable bankruptcy, insolvency, moratorium or other laws affecting creditors'
rights generally or such principles of equity as a court of competent
jurisdiction might apply.

              (c)     The Collateral is now and, so long as any of the Secured 
Obligations are outstanding, will continue to be owned solely by Debtor. Except
as provided in Section 1(d) above, and except for purchase money security
interests, the Collateral is, and from time to time hereafter will be, free from
any lien or other right, title or security interest of any person other than
Secured Party. Debtor shall defend the Collateral against all claims and demands
of all persons at any time claiming the same or any interest therein adverse to
Secured Party, except for claims and demands of persons holding purchase money
security interests and except for claims and demands of persons holding
interests to which Secured Party has subordinated or to which Secured Party is
required to be subordinate to pursuant to Section 1(d) above.

              (d)     Assuming the filing of the UCC-1 Financing Statement in 
the form attached hereto as Exhibit A in the appropriate state or county
governmental office, the payment of all requisite fees in connection with such
filing and the satisfaction of all other filing requirements imposed by statute
or otherwise, all filings, registrations and recordings necessary or appropriate
to create, preserve, protect and perfect the security interest granted by Debtor
to Secured Party hereby in respect of the Collateral will have been accomplished
and the security interest granted to Secured Party pursuant to this Agreement in
and to the Collateral will constitute a valid and enforceable perfected security
interest therein, and Secured Party is entitled to all the rights, priorities
and benefits afforded by the Wisconsin Uniform Commercial Code or other relevant
law as enacted in any relevant jurisdictions to perfected security interests.

               (e)    There is no financing statement (or similar statement or 
instrument of registration under the law of any jurisdiction) other than Secured
Party's covering or purporting to cover any interest of any kind in the
Collateral and so long as any of the Secured Obligations remain unpaid, Debtor
will not execute or authorize to be filed at any public office any other
financing statement (or similar statement or instrument of registration under
the law of any jurisdiction) or statements relating to the Collateral, except
financing statements filed or to be filed in respect of and covering the
security interest granted hereby by Debtor, except for interests permitted by
Section 1(d) and 2(c) above. Debtor further covenants that it will not grant any
additional security interests which rank in priority to the security interest in
the Collateral granted in this Agreement in the assets, properties or the
business of Debtor without the prior written consent of Secured Party except for
interests permitted by Sections 1(d) and 2(c) above.

              (f)     No representations or warranties of Debtor contained in 
this Agreement or in any document, statement or certificate furnished or to be
furnished pursuant to this Agreement, contain an untrue statement of a material
fact, or omit to state a material fact necessary to make the statements of fact
herein not misleading.

      3.      Covenants of Debtor.  Until payment in full of all Secured 
Obligations, Debtor agrees that, unless Secured Party shall have otherwise 
consented in writing:
   33
              (a)    Debtor shall execute and take such action as may reasonably
be requested from time to time by Secured Party, including the execution and
delivery of financing statements and certificates of title, and the filing of
financing statements, as may be necessary to perfect and maintain the security
interest granted to Secured Party hereby. In the event Debtor refuses or fails
to timely execute and deliver any financing statement reasonably requested by
Secured Party, Debtor authorizes Secured Party to file any such financing
statements without the signature of Debtor.

              (b)     Debtor shall not misuse, abuse, waste or allow to 
deteriorate the Collateral, except for ordinary wear and tear. Secured Party may
examine and inspect the Collateral, wherever located, during normal business
hours and upon at least 48 hours' prior notice to Debtor. Debtor will insure the
Collateral against all risks to which the Collateral is exposed in the ordinary
course, and shall cause Secured Party to be named as loss payee thereunder to
the extent of its interest therein.

              (c)     Debtor shall pay and discharge all taxes, assessments and 
governmental charges or levies imposed upon it or its property or assets, prior
to the date on which penalties attach thereto, and all lawful claims (except as
permitted by Sections 1(d) and 2(c) above) which, if unpaid, would become a lien
or charge upon the Collateral, except to the extent that the imposition of any
such tax, assessment, charge or levy or the validity of any such claim is being
contested in good faith by the appropriate proceedings.

              (d)     Debtor shall notify Secured Party within ten (10) days of
any change in (i) Debtor's corporate name, (ii) Debtor's business or legal
structure, or (iii) Debtor's place of business or chief executive office if the
Debtor has more than one place of business. The Collateral will at all times be
kept by Debtor at Debtor's place of business in the State of Wisconsin or the
United Kingdom, and shall not, be moved therefrom except, prior to an Event of
Default, the Collateral may be moved to locations within the continental United
States other than that listed above if (i) Debtor gives Secured Party written
notice of a new storage location at least thirty (30) days prior to storing
Collateral at such location, (ii) Secured Party's security interest in such
Collateral is and continues to be a duly perfected lien thereon, (iii) neither
Secured Party's nor Debtor's right of entry upon the premises where such
Collateral is stored, or its right to remove the Collateral therefrom, is in any
way restricted, (iv) the owner of such premises agrees with Secured Party not to
assert any landlord's, bailee's or other lien in respect of the Collateral for
unpaid rent or storage charges and (v) all negotiable documents and receipts in
respect of any Collateral maintained at such premises are properly delivered to
Secured Party. No Collateral is now, nor shall any Collateral at any time or
times hereafter be, stored with a bailee, warehouseman or similar party without
Secured Party's prior written consent and, if Secured Party gives such consent,
Debtor will concurrently therewith cause any such bailee, warehouseman or
similar party to issue and deliver to Secured Party, in form and substance
acceptable to Secured Party, warehouse receipts therefor in Secured Party's
name.

      4.      Events of Default.  The occurrence of any one or more the 
following events shall constitute an "Event of Default" hereunder:
   34
              (a)     Event of Default Pursuant to Transaction Documents. There 
shall occur an Event of Default pursuant to the Note or the Tangible Assets
Promissory Note or Debtor shall fail or neglect to perform, keep or observe any
covenant or obligation of Debtor as set forth in Sections 2.2, 15.1 or 15.3 of
the Purchase Agreement which breach is not cured within 30 days following
receipt by Debtor of written notice thereof.

              (b)     Misrepresentation. Any warranty or representation of 
Debtor to Secured Party in this Security Agreement is determined by a court of
competent jurisdiction to have been false or misleading in any material respect
when made.

              (c)     Breach of Covenants. Debtor shall fail or neglect to 
perform, keep or observe any covenant or obligation of Debtor contained in this
Security Agreement and the breach of any such covenant or obligation is not
cured within thirty (30) days after Debtor's receipt of written notice of such
breach from Secured Party.

              (d)     Insolvency, Etc. The Debtor shall commence a voluntary 
case concerning itself under Title 11 of the United States Code entitled
"Bankruptcy" as now or hereafter in effect; or an involuntarily case shall be
commenced against the Debtor and the petition shall not be controverted within
thirty (30) days, or shall not be dismissed within one hundred eighty (180) days
after commencement of the case; or a custodian shall be appointed for, or shall
take charge of, all or substantially all of the property of the Debtor, or the
Debtor shall commence any other proceeding under any reorganization,
arrangement, adjustment of debt, relief of debtors, dissolution, insolvency or
liquidation or similar law of any jurisdiction whether now or hereafter in
effect relating to the Debtor, or there shall be commenced against the Debtor
any such proceeding, or the Debtor shall be adjudicated insolvent or bankrupt.

      5.      Secured Party's Rights and Remedies.

              (a)     Upon the occurrence of an Event of Default as hereinabove 
set forth, Secured Party may exercise all rights or remedies that Secured Party
may have as a secured party under the Uniform Commercial Code.

              (b)     Upon the occurrence of any Event of Default, as 
hereinabove set forth, Secured Party may sell, lease or otherwise dispose of all
or any part of the Collateral upon any terms which are commercially reasonable.
Debtor agrees that fifteen (15) days prior written notice to Debtor of any
public or private sale or other disposition of the Collateral shall be
reasonable notice thereof, and such sale shall be at such location as Secured
Party may designate in such notice.

              (c)     All proceeds from the sale or other disposition of the 
Collateral, and all other amounts received by Secured Party pursuant to the
terms of this Agreement, unless otherwise expressly required by law or
regulation, shall be applied as follows:

                      (i)     First, to the payment of all expenses reasonably 
incurred by Secured Party in connection with any sale or disposition of the
Collateral, including, but not limited to, the 
   35
expenses of taking, advertising, processing, preparing and storing the
Collateral to be sold, and all court costs and all reasonable legal fees of
Secured Party in connection therewith;

                      (ii)    Second, to the payment of all obligations owed to 
Secured Party pursuant to the Secured Royalty Promissory Note-No. 1 and which
have come due and are unpaid;

                      (iii)   Third, to the payment of all obligations owed 
Secured Party pursuant to the Secured Royalty Promissory Note-No. 2 which have
come due and are unpaid;

                      (iv)    Fourth, to the payment of all obligations owed

                      (v)     Fifth, the balance, if any, to Debtor.

Debtor shall remain liable to the extent of any deficiency between the amount of
the proceeds of the Collateral and the aggregate amount of the sums referenced
in clauses (i) and (ii) of this Section 5(c).

              (d)     No delay or omission by Secured Party in exercising any 
right or remedy hereunder or with respect to any obligation of Debtor to Secured
Party secured hereunder shall operate as a waiver thereof or of any other right
or remedy available to Secured Party, and no single or partial exercise thereof
shall preclude any other or further exercise thereof or the exercise of any
other right or remedy. Secured Party, in its sole discretion, on at least seven
(7) days' prior written notice to Debtor, may (but shall have no obligation to)
remedy any Event of Default by Debtor hereunder or with respect to any
obligation of Debtor to the Secured Party or any other person, firm, corporation
or other entity in any reasonable manner without waiving the Event of Default
remedied and without waiving any other prior or subsequent Event of Default by
Debtor, and shall be reimbursed for its necessary and reasonable out-of-pocket
expenses in so remedying any of such Event of Default. All rights and remedies
of Secured Party hereunder are cumulative.

      6.      Miscellaneous.

              (a)     Further Acts. Debtor and Secured Party shall execute and 
deliver all instruments and documents and shall perform all other acts which the
other may reasonably request in order to effect the rights and obligations of
the parties hereto and the other transactions contemplated in this Agreement.

NOTE

US $______________________                                _______________, 1996


         FOR VALUE RECEIVED, STRATEGIC ADVANTAGE SOFTWARE CORPORATION, a
Wisconsin corporation with offices located at 1810 Thorstrand Road, Madison,
Wisconsin 53705 (the "Maker") promises to pay to the order of CYPHER BUSINESS
SYSTEMS, LTD., a corporation organized under the laws of England and Wales with
offices at c/o Platinum Software Corporation, 195 Technology Drive, Irvine,
California 92718 ("Cypher"), or such other place as the holder (the "Holder") of
this Secured Tangible Assets Promissory Note (this "Note") may from time to time
in writing direct, the principal sum of__________________ United States Dollars
(US$ _________), payable in sixty (60) equal installments of principal in the
amount of United States Dollars (US$____), together with accrued interest at
the rate of eight percent (8%) per annum on the unpaid principal balance from
the date of Tangible Asset Closing, on the first day of each calendar month
commencing on the first day of the month following the six (6) month anniversary
of the Tangible Asset Closing, until such principal balance and accrued interest
are paid in full. Attached hereto as Exhibit 1 is an amortization schedule.

         This Note is the Tangible Assets Note referred to in that certain
Agreement of Purchase and Sale of Assets, dated as of February 29, 1996, between
the Maker and Platinum Software Corporation, Cypher and Slatershelfco 173
Limited (the "Purchase Agreement") and is secured by a security interest created
under that certain Security Agreement of even date (the "Security Agreement")
between Maker and Cypher, and Cypher is entitled to all of the benefits and
security of the collateral as set forth in the Security Agreement. Capitalized
terms used herein and not otherwise defined shall have the meanings assigned to
them in the Purchase Agreement.

         All amounts due hereunder shall be payable in lawful money of the
United States. Overdue principal and, to the extent permitted by law, overdue
interest in respect of this Note shall bear interest at a rate per month equal
to one (1) percent or the maximum rate permitted by law, whichever is less.
Prepayment of principal hereunder may be made at any time without penalty.

         The principal amount of this Note and all accrued but unpaid interest
thereon shall become immediately due and payable, at the option of Cypher, upon
the occurrence of any of the following (an "Event of Default"):

         (a)      Any payment due under this Note shall have been in default for
at least thirty (30) days following the receipt of a written notice of default
in payment;
   40
         (b)      The Maker shall fail or neglect to perform, keep or observe 
any covenant or obligation of Maker as set forth in Sections 2.2, 15.1 and 15.3
of the Purchase Agreement, which breach is not cured within thirty (30) days
following receipt by Maker of written notice thereof; or

         (c)      The Maker fails or neglects to comply with any covenant or 
obligation of Maker set forth in the Security Agreement which breach is not
cured within the cure period provided in the Security Agreement;

         (d)      The Maker shall commence a voluntary case concerning itself 
under Title 11 of the United States Code entitled "Bankruptcy" as now or
hereafter in effect; or an involuntarily case shall be commenced against the
Maker and the petition shall not be controverted within thirty (30) days, or
shall not be dismissed within one hundred eighty (180) days after commencement
of the case; or a custodian shall be appointed for, or shall take charge of, all
or substantially all of the property of the Maker, or the Maker shall commence
any other proceeding under any reorganization, arrangement, adjustment of debt,
relief of debtors, dissolution, insolvency or liquidation or similar law of any
jurisdiction whether now or hereafter in effect relating to the Maker, or there
shall be commenced against the Maker any such proceeding, or the Maker shall be
adjudicated insolvent or bankrupt; or

         (e)      Greater than fifty percent (50%) of the voting capital stock 
of the Maker passes without the consent of Cypher to any person, firm or company
acting either individually or in concert, provided that transfers of shares
between the registered shareholders of Maker as of the date hereof will not be
considered a change of control. Notwithstanding the foregoing sentence, no
consent of Cypher shall be required for any transaction or series of
transactions prior to June 30, 1998 in which Maker secured capital or funding
for business operations.

         The Maker hereby waives presentment for payment, protest and notice of
nonpayment and dishonor. If the Holder takes any action to collect this Note,
then the Maker shall be obligated to pay, in addition to all other amounts due
under this Note, all costs of collection and reasonable attorneys' fees and
other legal costs and expenses, provided that Maker is determined by a court of
competent jurisdiction to be liable for the amount sought to be collected.

         No delay or failure on the part of the Holder in the exercise of any
right or remedy hereunder shall operate as a waiver thereof, nor as an
acquiescence in any default, nor shall any single or partial exercise by the
Holder of any right or remedy preclude any other right or remedy. The Holder, at
its option, may enforce its rights against any collateral securing this Note
without enforcing its rights against the Maker or any other indebtedness due or
to become due to the Maker. The Maker agrees that, without releasing or
impairing the Maker's liability hereunder, the Holder may at any time release,
surrender, substitute or exchange any collateral securing this Note and may
release any party secondarily liable for the indebtedness evidenced by this
Note.

         This Note shall be governed by and construed in accordance with the
internal laws of the State of California of the United States. Cypher and Maker
each irrevocably agree that all actions 

                                       2
   41
arising directly or indirectly as a result or in consequence of this Note shall
be instituted and litigated only in courts having situs in the State of
California, and Cypher and Maker each hereby consent to the exclusive
jurisdiction and venue of any state or federal court located and having its
situs in the State of California.

         IN WITNESS WHEREOF, the Maker has caused this Note to be executed and
delivered on the day and year first above written.

                                 DEED OF RELEASE

         THIS DEED OF RELEASE (the "Release"), dated and effective as of
______________, 1996, is entered into by and among PLATINUM SOFTWARE CORPORATION
("PSC"), CYPHER BUSINESS SYSTEMS, LTD. ("Cypher"), SLATERSHELFCO 173 LIMITED
("Slatershelfco"), JACK MUNDY, DAVID MUNDY, ABACUS TRUSTEES (JERSEY) LIMITED
("Abacus") and WHITELEY TRUSTEES LIMITED ("Whiteley"), Abacus and Whiteley as
trustees of the Jack Mundy Trust dated 10 March 1989.

                                 R E C I T A L S

         A.    On or about May 5, 1993, PSC acquired all of the outstanding 
share capital of Slatershelfco, the parent organization of Cypher, pursuant to a
purchase agreement (the "Purchase Agreement") and in connection with such
transaction Cypher entered into a Service Agreement (the "Service Agreement")
with each of Jack Mundy and David Mundy.

         B.    By acquiring all of the share capital of Slatershelfco, Platinum 
acquired ownership of Cypher whose principal business was the development and
sale of a distribution software product.

         C.    The parties hereto desire finally to resolve any claims that they
may have against the other, including, but not limited to, claims under each of
the Service Agreements, the Purchase Agreement, the Restrictive Covenant and
Warranty Deed, the deeds of Tax Indemnity and all other ancillary transaction
documents (collectively, the "Purchase Documents").

         D.    PSC, Cypher and Slatershelfco are in the process of selling the
distribution software product to a newly formed corporation, Strategic Advantage
Software Corporation, and the parties hereto intend that this Release be
effective simultaneously upon the closing of such sale.

                                A G R E E M E N T

         Upon full and complete execution of this Release and payment to each of
Jack Mundy and David Mundy of an amount required to bring their respective
Service Agreements current and funded through May 31, 1996, and in consideration
of the mutual covenants and releases contained herein, PSC, Cypher,
Slatershelfco, Jack Mundy, David Mundy, Abacus and Whiteley, forever mutually
release, acquit and discharge each other, as well as, to the extent applicable,
their respective officers, directors, employees, agents, administrators, and any
parent, subsidiary or affiliated entity, past, present or future, from any and
all claims, demands, costs, contracts liabilities, objections, actions and
causes of action of every nature, whether in law or in equity, or known or
unknown, or suspected or unsuspected, which the parties ever had or now have or
may claim to have against each other of any type, nature or description which in
any way arise out of, are related to, or are connected with the Purchase
Documents or the employment of Jack Mundy and David Mundy by Cypher,
Slatershelfco and PSC, as applicable ("Released Claims"), save and except the
obligations set forth, created, or preserved in this Release. Further, in
consideration of the above, Cypher and Jack Mundy and David Mundy each agree to
the extent applicable to them that each of the Service Agreements is mutually
terminated on the date hereof. For the avoidance of doubt, Abacus and Whiteley
are hereby fully so released by PSC from their undertaking at clause 12 of the
Purchase Agreement.  The parties hereto 
   44
specifically intend that the release contained herein shall bar all Released 
Claims, including those which are currently unknown to them.

         Notwithstanding anything to the contrary above, section 4 of the
Restrictive Covenant and Warranty Deed and section 12 of each of the Service
Agreements regarding confidentiality of proprietary information shall remain in
full force and effect and such obligations shall not be relinquished or
extinguished as a result of this Release; provided, however, Jack Mundy and
David Mundy may provide services to Strategic Advantage Software Corporation in
any capacity, including, but not limited to, as an employee, agent, independent
contractor, partner, shareholder or director, free of the foregoing
restrictions. Except as otherwise provided in the prior sentence, this Release
sets forth the entire agreement between the parties and supersedes and all prior
agreements or understandings in connection with the subject matters of this
Release, and the parties hereto agree that all continuing and future obligations
under the Purchase Documents are terminated upon the effectiveness of this
Release.

         It is agreed between Cypher and each of David Mundy and Jack Mundy that
in relation to the release of any claim Jack Mundy and David Mundy may have in
respect of their Service Agreements, the conditions set forth in section 140 of
the Employment Protection (Consolidation) Act 1978 regulating compromise
agreements are satisfied.

         The effectiveness of this Release is contingent upon the execution and
completion of a definitive purchase agreement relating to the distribution
software product by and between Platinum and Strategic Advantage Software
Corporation.

         PSC has not assigned any of the warranties under the Purchase
Agreement, nor does the sale referred to in Recital D above assign such
warranties.

         This Release is governed by and shall be construed in accordance with
the laws of England. If any provision of this Release is held by a court of
competent jurisdiction to be invalid, void or unenforceable for any reason, the
remaining provisions not so declared shall nevertheless continue in full force
and effect, but shall be construed in a manner so as to effectuate the intent of
this Release as a whole, notwithstanding such stricken provision or provisions.

         The parties hereto hereby submit to the exclusive jurisdiction of the
High Court of Justice in England in relation to any claim, dispute or difference
which may arise hereunder.
   45
         IN WITNESS WHEREOF, the parties have executed this Deed of Release as
their deed and delivered it on the date first above written.

                                   EXHIBIT E

                       FORM OF OPINION OF BUYER'S COUNSEL


      1.      The Buyer is a company duly incorporated, validly existing and in
good standing under the laws of the State of Wisconsin.  The Buyer has the
corporate power and authority to own its properties and assets, to carry on its
business as presently conducted and to enter into the Purchase Agreement, the
Royalty Note-No. 1, the Royalty Note-No. 2, the Tangible Assets Promissory Note,
the Security Agreement, (the "Transaction Documents"), and to perform its
obligations under the Transaction Documents.

      2.      Each of the Transaction Documents has been duly authorized by all
necessary corporate action on the part of the Buyer and has been duly executed
and delivered by the Buyer.  Each of the Transaction Documents is a legal, valid
and binding obligation of the Buyer enforceable against it in accordance with
its respective terms, except as the enforceability thereof may be subject to or
limited by (a) bankruptcy, insolvency, reorganization, arrangement, moratorium
or other similar laws relating to or affecting rights or creditors, and (b)
general equitable principles, regardless of whether the issue of enforceability
is considered in a proceeding in equity of law.

      3.      The execution and delivery of the Transaction Documents and the
performance by the Buyer of their respective terms (a) will not breach or result
in a violation of the Buyer's charter documents, or any judgment, order or
decree of any court or arbitrator, known to us, to which the Buyer is a party or
is subject, and (b) will not constitute a material breach of the terms,
conditions or provisions of, or constitute a default under, any material
contract, undertaking, indenture or other agreement or instrument known to such
counsel to which the Buyer is a party or by which it is bound.

      4.      No consent, approval or authorization of, or designation,
declaration or filing with, any governmental authority is required in connection
with the valid execution, delivery and performance by the Buyer of the
Transaction Documents, other than such consents, approvals, authorizations,
designations, declarations or filings as have been made or obtained on or before
the date hereof or which are not required to be made or obtained until after the
date hereof.

      5.      Except as disclosed in the Purchase Agreement or the Exhibits and
Schedules delivered by the Buyer in connection therewith, there is, to such
counsel's current actual knowledge, no action, suit or proceeding pending
against the Buyer or its properties in any court or before any governmental
authority or agency, or arbitration board or tribunal, (a) which seeks to
restrain, enjoin, prevent the consummation of or otherwise challenge the
Agreement or any of the transactions contemplated thereby, or (b) which, if
adversely determined, could have a material adverse effect on the Buyer or its
business or properties.

      6.      The provisions of the Security Agreement are sufficient to create
a security interest in those items and types of Collateral in which a security
interest may be created under Article 9 of the Wisconsin Uniform Commercial Code
(the "Article 9 Collateral").  The UCC-1 Financing Statement of the Buyer in the
form presented to such counsel is in adequate and legally sufficient form with
regard to Article 9 Collateral for which perfection may occur by the filing of a
UCC-1 Financing Statement with the Secretary of State of Wisconsin.  The place
for filing such
   49
UCC-1 Financing Statement for Article 9 Collateral, for which perfection may
occur by the filing of a UCC-1 Financing Statement, other than fixtures, is with
the Secretary of State for the State of Wisconsin in accordance with the
provisions of the Wisconsin Uniform Commercial Code.

Strategic Advantage Software Corporation
c/o DeWitt Ross & Stevens
8000 Excelsior Drive, Suite 401
Madison, Wisconsin  53717

             RE:   Platinum Software Corporation

Ladies and Gentlemen:

      We have acted as counsel to Platinum Software Corporation, a Delaware
corporation (the "Company"), in connection with the execution and delivery by
the Company of that certain Agreement of Purchase and Sale of Assets, dated as
of February 29, 1996 (the "Agreement") among the Company, Cypher Business
Systems, Ltd., a corporation organized under the laws of England and Wales,
Slatershelfco 173 Limited, a corporation organized under the laws of England and
Wales and Strategic Advantage Software Corporation, a Wisconsin corporation (the
"Buyer").  This opinion is being delivered pursuant to Section 11.10 of the
Agreement.  Unless specifically defined herein or the context requires
otherwise, capitalized terms used herein shall have the meanings assigned to
them in the Agreement.

      In connection with the preparation of this opinion, we have examined such
documents and considered such questions of law as we have deemed necessary or
appropriate.  We have assumed that, except for the Agreement and the documents
required or contemplated thereby, there are no other documents or agreements
between the Company and Buyer which would expand or otherwise modify the
respective rights and obligations of the Company or Buyer as set forth in the
Agreement and the documents required or contemplated thereby.

      We have assumed the authenticity of all documents submitted to us as
originals, the conformity with originals of all documents submitted to us as
copies, and the genuineness of all signatures.  We have also assumed that, with
respect to all parties to agreements or instruments relevant hereto other than
the Company, such parties had the requisite power and authority to execute,
deliver and perform such agreements or instruments, that such agreements or
instruments
   54
Strategic Advantage Software Corporation

Page 2


have been duly authorized by all requisite action, executed and delivered by
such parties and that such agreements or instruments are the valid, binding and
enforceable obligations of such parties.

      As to questions of fact material to our opinions, we have relied upon the
representations of each party made in the Agreement and other documents and
certificates delivered in connection therewith, certificates of officers of the
Company, and certificates and advices of public officials and we have made no
independent investigation of such matters.

      Whenever a statement herein is qualified by "known to us," "to our current
actual knowledge," or similar phrase, it is intended to indicate that, during
the course of our representation of the Company, no information that would give
us current actual knowledge of the inaccuracy of such statement has come to the
attention of those attorneys in this firm who have rendered legal services in
connection with the transaction described in the introductory paragraph hereof.
However, except as otherwise expressly indicated, we have not undertaken any
independent investigation to determine the accuracy of such statement, and any
limited inquiry undertaken by us during the preparation of this opinion letter
should not be regarded as such an investigation; no inference as to our
knowledge of any matters bearing on the accuracy of any such statement should be
drawn from the fact of our representation of the Company.

      Based upon the foregoing, and subject to the assumptions, exceptions,
qualifications and limitations set forth herein, we are of the opinion that:

      1.     The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware.  The Company has the
corporate power and authority to own its properties and assets, to carry on its
business as presently conducted and to enter into the Agreement and the Bill of
Sale, General Conveyance and Assignment (the "Transaction Documents"), and to
perform its obligations under the Transaction Documents.

      2.     Each of the Transaction Documents has been duly authorized by all
necessary corporate action on the part of the Company and has been duly executed
and delivered by the Company.  Each of the Transaction Documents is a legal,
valid and binding obligation of the Company enforceable against it in accordance
with its respective terms, except as the enforceability thereof may be subject
to or limited by (a) bankruptcy, insolvency, reorganization, arrangement,
moratorium or other similar laws relating to or affecting rights of creditors,
and (b) general equitable principles, regardless of whether the issue of
enforceability is considered in a proceeding in equity or law.

      3.     The execution and delivery of the Transaction Documents and the
performance by the Company of their respective terms (a) will not breach or
result in a violation of the Company's Certificate of Incorporation or Bylaws,
or any judgment, order or decree of any court or arbitrator, known to us, to
which the company is a party or is subject, and (b) will not constitute a 
material breach of the terms, conditions or provisions of, or constitute a 
default under, any material contract,
   55
Strategic Advantage Software Corporation
March __, 1996
Page 3


undertaking, indenture or other agreement or instrument filed as an exhibit to
the Company's Annual Report on Form 10-K for the fiscal year ended June 30,
1995.

      4.     No consent, approval or authorization of, or designation,
declaration or filing with, any governmental authority is required in connection
with the valid execution, delivery and performance by the Company of the
Transaction Documents, other than such consents, approvals, authorizations,
designations, or filings listed in the Agreement and Schedule 5.3 thereto or as
have been made or obtained on or before the date hereof or which are not
required to be made or obtained until after the date hereof.

      5.     Except as disclosed in the Agreement or the Exhibits and Schedules
delivered by the Company in connection therewith, there is, to our current
actual knowledge, no action, suit or proceeding pending against the Company or
its properties in any court or before any governmental authority or agency, or
arbitration board or tribunal, (a) which seeks to restrain, enjoin, prevent the
consummation of or otherwise challenge the Agreement or any of the transactions
contemplated thereby or (b) which if adversely determined could have a material
adverse effect on the Company, or its business or properties.

      We expressly do not comment upon or render any opinion with respect to any
documents referenced in the Transaction Documents.

      We are members of the Bar of the State of California and, accordingly, do
not purport to be experts on or to be qualified to express any opinion herein
concerning, nor do we express any opinion herein concerning, any laws other than
the laws of the State of California, the General Corporation Law of Delaware and
federal law.

      The foregoing opinions are being furnished to you solely for your benefit
and may not be relied upon by any other person without our prior written
consent.


                                       Very truly yours,

                                       /s/ Stradling, Yocca, Carlson & Rauth
