                               SUMMARY TERM SHEET

     This summary term sheet is a brief description of the Offer being made by
Geac Computer Corporation Limited ("Geac") through Conductor Acquisition Corp.
("Purchaser"), an indirect wholly owned subsidiary of Geac, to purchase all of
the outstanding shares of common stock, par value $1.00 per share (the
"Shares"), of Comshare, Incorporated ("Comshare" or the "Company"), including
the associated Series A Preferred Stock Purchase Rights (the "Rights") attached
thereto issued pursuant to the Rights Agreement, dated September 16, 1996,
between the Company and Computershare Investor Services LLC, as successor to
KeyBank National Association, Key Corp Shareholder Services, Inc. and Harris
Trust and Savings Bank's corporate trust business (the "Rights Agreement"), at a
price of $4.60 net per share in cash. The following are answers to some of the
questions you, as a shareholder of Comshare, may have about the Offer. We urge
you to read this Offer to Purchase and the accompanying Letter of Transmittal in
their entirety because the information in this summary term sheet is not
complete, and additional important information is contained in the remainder of
this Offer to Purchase and in the Letter of Transmittal.

Q.  WHO IS OFFERING TO BUY MY SECURITIES?

     The Purchaser is Conductor Acquisition Corp. We are a Michigan corporation
formed for the purpose of making this tender offer. We are an indirect wholly
owned subsidiary of Geac, a corporation governed by the Canada Business
Corporations Act. The tender offer is the first step in Geac's plan to acquire
all of the outstanding Shares. See "Introduction" and Section 9.

Q.  WHAT IS CONDUCTOR ACQUISITION CORP. SEEKING TO PURCHASE, AT WHAT PRICE, AND
    WILL I HAVE TO PAY ANY BROKERAGE OR SIMILAR FEES TO TENDER?

     We are offering to purchase all of the outstanding Shares, including the
associated Rights. We are offering to pay $4.60 per Share, net to you, in cash
and without interest. If you are the record owner of your Shares and you tender
your Shares to us in the Offer, you will not have to pay any brokerage or
similar fees. If you own your Shares through a broker or other nominee, your
broker or nominee may charge you a fee to tender your Shares on your behalf. You
should consult your broker or nominee to determine whether any charges will
apply. You should also consult your tax advisor regarding the particular tax
consequences to you of tendering your Shares. See "Introduction" and Sections 1
and 5.

Q.  WHAT ARE THE ASSOCIATED PREFERRED STOCK PURCHASE RIGHTS?

     The associated preferred stock purchase Rights were issued to all
shareholders of the Company in connection with the Company's adoption in 1996 of
an anti-takeover device of the type commonly known as a "rights plan" or a
"poison pill," but currently are not represented by separate certificates.
Instead, these Rights are represented by the certificates of your Shares. Unless
Rights are separately distributed to shareholders (which we do not expect to
occur), a tender of your Shares will automatically include a tender of the
associated Rights. We will not pay any additional consideration for the tender
of any Right.

Q.  DO YOU HAVE THE FINANCIAL RESOURCES TO PAY FOR MY SECURITIES?

     Yes. Geac, the Purchaser's parent company, will provide us with sufficient
funds to purchase all Shares tendered in the Offer and any Shares to be acquired
in the Merger that is expected to follow the successful completion of the Offer.
The Offer is not subject to any financing condition. See Section 13.

Q.  IS YOUR FINANCIAL CONDITION OR THAT OF GEAC RELEVANT TO MY DECISION TO
    TENDER IN THE OFFER?

     We do not think our financial condition or that of Geac is relevant to your
decision whether to tender Shares and accept the Offer because:

     - the Offer is being made for all outstanding Shares solely for cash;

                                        5


     - our obligation to purchase your Shares in the Offer is not subject to any
       financing condition; and

     - if we complete the Offer, we will acquire all remaining Shares for the
       same cash price in the Merger.

     See "Introduction" and Sections 1, 11 and 12.

Q.  HOW LONG DO I HAVE TO DECIDE WHETHER TO TENDER IN THE OFFER?

     You will have until at least 12:00 midnight, Eastern time, on July 30,
2003, to tender your Shares in the Offer. Under certain circumstances, we may
extend the Offer. If the Offer is extended, we will issue a press release
announcing the extension on the first business morning following the date the
Offer was scheduled to expire. See Section 1.

Q.  WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

     The most significant conditions to the Offer are the following:

     - that prior to the expiration date of the Offer, Comshare shareholders
       have validly tendered in accordance with the terms of the Offer, and not
       withdrawn, that number of Shares that, together with any other Shares
       then owned by Geac, Purchaser or any affiliate of Geac or Purchaser on
       the date such Shares are purchased, represents at least a majority of the
       total outstanding Shares of the Company, calculated on a fully diluted
       basis; and

     - that the applicable waiting period under the Hart-Scott-Rodino Antitrust
       Improvements Act of 1976, as amended (the "HSR Act"), and any laws, rules
       or regulations analogous to the HSR Act existing in foreign
       jurisdictions, have expired or been terminated.

     The Offer is also subject to a number of other customary conditions. For a
complete list of the conditions to the Offer, see section 15.

Q.  HOW DO I TENDER MY SHARES?

     To tender your Shares before the Offer expires:

     - if you hold physical certificates (meaning you hold certificates issued
       in your name), you must deliver your certificate(s) for the Shares you
       wish to tender and a properly completed and duly executed Letter of
       Transmittal to the Depositary at the address appearing on the back cover
       of this document;

     - if your broker holds your Shares in "street name," you must inform your
       broker of your decision to tender your Shares so that the Depositary
       receives a confirmation of receipt of your Shares by book-entry transfer
       and a Letter of Transmittal; or

     - you or your broker must comply with the guaranteed delivery procedure.

     In any case, the Depositary must receive all required documents prior to
12:00 midnight, Eastern time, on Wednesday, July 30, 2003, or, if the Offer is
extended, the date and time to which the Offer is extended.

     If you have any questions, you should contact the Information Agent or your
broker for assistance. See Section 3.

Q.  IF I ACCEPT THE OFFER, WHEN WILL I BE PAID?

     Provided the conditions to the Offer are satisfied and we complete the
Offer and accept any Shares for payment, you will receive a payment equal to the
number of Shares you tendered multiplied by $4.60, subject to any required
withholding for taxes, as promptly as practicable following the expiration of
the Offer. See Section 2.

                                        6


Q.  CAN I WITHDRAW SHARES ONCE I HAVE TENDERED THEM?

     You may withdraw some or all of your tendered Shares by delivering written
notice to the Depositary at any time prior to the expiration of the Offer.
Further, if we have not agreed to accept your Shares for payment by August 30,
2003, you may withdraw them at any time after that date. Once Shares are
accepted for payment, they cannot be withdrawn. Your right to withdraw will not
apply to any Subsequent Offering Period, if one is provided. See Section 4.

Q.  HAVE ANY SHAREHOLDERS AGREED TO TENDER THEIR SHARES?

     Yes. Dennis G. Ganster, Codec Systems Limited and Anthony Stafford, who
together own approximately 15% of the outstanding Shares as of June 22, 2003,
have each agreed to support the transaction and tender their respective Shares
pursuant to our Offer. See Section 12.

Q.  WHAT IS THE "TOP-UP OPTION" AND HOW CAN IT BE EXERCISED?

     We have received an option, which we call the "Top-Up Option," from the
Company which will allow us to purchase additional Shares of the Company at
$4.60 per Share to enable us to own 90% of the outstanding Shares. The Top-Up
Option will be exercisable by us in the event more than 80% but less than 90% of
the outstanding Shares are tendered in the Offer. If we exercise the Top-Up
Option, we will be able to complete the Merger without a shareholder vote. See
Section 12.

Q.  WHAT DOES THE BOARD OF DIRECTORS OF COMSHARE THINK OF THIS OFFER?

     The Comshare board of directors (the "Company Board") has unanimously
determined that the Merger Agreement and the Transactions are fair to and in the
best interests of the Company's shareholders; has unanimously approved and
adopted the Merger Agreement and the Transactions, including the Offer and
Merger, in accordance with the requirements of Michigan law; and has agreed to
recommend that the Company's shareholders accept the Offer, and approve and
adopt the Merger Agreement and the Merger. See "Introduction."

Q.  WHAT WILL HAPPEN TO COMSHARE?

     If the Offer is consummated, and Purchaser thereby acquires at least 90% of
the then outstanding Shares, Purchaser will immediately, without any further
action by the shareholders of the Company, be merged with and into Comshare,
with Comshare surviving as an indirect wholly owned subsidiary of Geac. If,
after the consummation of the Offer, the Purchaser holds less than 90% of the
then outstanding Shares, then the Company will schedule a meeting of its
shareholders to approve the Merger. At that meeting, the Purchaser will hold a
majority of the outstanding Shares of the Company, and will vote those Shares in
favor of the Merger. After adoption and approval by the shareholders of the
Merger Agreement and the Merger, the Purchaser will immediately be merged with
and into the Company, with the Company surviving as an indirect, wholly owned
subsidiary of Geac. See "Introduction" and Section 11.

Q.  IF I DO NOT TENDER BUT THE TENDER OFFER IS SUCCESSFUL, WHAT WILL HAPPEN TO
    MY SHARES?

     If the Merger takes place, shareholders who do not tender in the Offer will
receive in the Merger the same amount of cash per Share that they would have
received had they tendered their Shares in the Offer. Therefore, if the Merger
takes place, the only difference to you between tendering your Shares and not
tendering your Shares is that you will be paid earlier if you tender your
Shares. However, in the event, which we consider unlikely, that the Offer is
completed and the Merger does not take place (for example, because one or more
conditions in the Merger Agreement cannot be satisfied), the number of
shareholders and the number of Shares of Comshare that are still held by persons
other than Geac, Purchaser or their affiliates may be so small that there may no
longer be an active public trading market (or, possibly, any public trading
market) for the Shares. Also, the Shares may no longer be eligible to be traded
on the Nasdaq National Market or any other securities exchange, and Comshare
may, if otherwise permitted to do so, cease making

                                        7


filings with the SEC or otherwise cease being required to comply with the SEC's
rules relating to publicly held companies. See Sections 7 and 12.

Q.  ARE APPRAISAL RIGHTS AVAILABLE IN EITHER THE OFFER OR THE MERGER?

     No. Appraisal rights are not available in the Offer, and if the Offer is
consummated, appraisal rights will not be available in the Merger. See Section
12.

Q.  WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER AND THE MERGER?

     The receipt of cash by you in exchange for your Shares pursuant to the
Offer or the Merger is a taxable transaction for U.S. federal income tax
purposes and may also be a taxable transaction under applicable state, local or
foreign tax laws. In general, you will recognize capital gain or loss equal to
the difference between your adjusted tax basis in the Shares you tender and the
amount of cash you receive for those Shares. You should consult your tax advisor
about the particular tax consequences to you of tendering your Shares. See
Section 5 for a further discussion of U.S. federal income tax consequences of
tendering Shares.

Q.  WHAT IS THE MARKET VALUE OF MY SHARES AS OF A RECENT DATE?

     On June 20, 2003, the last Nasdaq National Market trading day before Geac
and Comshare announced that they had signed the Merger Agreement, the last sale
price of Comshare stock reported on the Nasdaq National Market was $3.64 per
share. The average sale price of Comshare's common stock during the twenty
trading days preceding the signing of the Merger Agreement, based on the last
sale price on each trading day as reported on the Nasdaq National Market, was
$3.52 per share. On June 30, 2003, the last sale price of Comshare stock on the
Nasdaq National Market was $4.55 per share. We advise you to obtain a recent
quotation for Comshare stock before deciding whether or not to tender your
Shares. See Section 6.

Q.  WHOM MAY I CALL WITH QUESTIONS?

     Questions or requests for assistance may be directed to the Information
Agent or to the Dealer Manager at their respective addresses and telephone
numbers set forth on the back cover of this Offer to Purchase. You may also
choose to contact your own tax, financial and legal advisors to discuss the
advisability of accepting or declining the Offer. See the back cover of this
Offer to Purchase.

                                  INTRODUCTION

     Conductor Acquisition Corp., a Michigan corporation ("Purchaser") and an
indirect wholly owned subsidiary of Geac Computer Corporation Limited, a
Canadian corporation ("Geac"), is offering to purchase all of the issued and
outstanding shares of common stock, par value $1.00 per share (the "Shares"), of
Comshare, Incorporated, a Michigan corporation ("Comshare" or the "Company"),
together with the Series A Preferred Stock Purchase Rights (the "Rights")
attached thereto issued pursuant to the Rights Agreement, dated September 16,
1996, between the Company and Computershare Investor Services LLC, as successor
to KeyBank National Association, Key Corp Shareholder Services, Inc. and Harris
Trust and Savings Bank's corporate trust business (the "Rights Agreement"), at a
purchase price of $4.60 per Share, net to the seller in cash, or any higher
price paid for each Share in the Offer, without interest thereon (the "Offer
Price"), on the terms and subject to the conditions set forth in this Offer to
Purchase and in the related Letter of Transmittal (which, as amended or
supplemented from time to time, collectively constitute the "Offer"). All
references to Rights include all benefits that may inure to holders of the
Rights under the Rights Agreement and, unless the context otherwise requires,
all references in this Offer to Purchase to Shares shall include the Rights.

     Shareholders whose Shares are registered in their own names and who tender
their Shares directly to the Depositary (as defined below) will not be obligated
to pay brokerage fees or commissions or, except as set forth in Instruction 6 of
the Letter of Transmittal, stock transfer taxes on the sale of Shares in the
Offer. However, shareholders that do not complete and sign the Substitute Form
W-9 that is included in the Letter of Transmittal, will be subject to a required
backup U.S. federal income tax withholding (at the rate of 30%). Shareholders
who hold their Shares through a bank or broker should check with such
institution as to whether it will charge any service fees. We will pay all fees
and expenses of the Depositary, the Information Agent and the Dealer Manager
incurred in connection with the Offer. See Section 5 for a further discussion of
U.S. federal income tax consequences of tendering Shares.

     We are making the Offer pursuant to the Agreement and Plan of Merger, dated
as of June 22, 2003 (the "Merger Agreement"), among Geac, Purchaser and the
Company. Following the completion of the Offer and the satisfaction or waiver of
certain conditions, Purchaser will merge with and into the Company (the
"Merger"), and the Company will be the surviving corporation in the Merger.
Pursuant to the Merger, each then remaining Share outstanding (other than Shares
held by (i) the Company or any of its subsidiaries and (ii) Geac, Purchaser or
any of Geac's direct or indirect wholly owned subsidiaries, all of which will be
cancelled) will be converted into the right to receive the Offer Price, or any
higher price per Share paid in the Offer, without interest.

     Concurrently with the execution of the Merger Agreement, Geac and Purchaser
entered into a Voting and Tender Agreement, each dated as of June 22, 2003 (the
"Voting and Tender Agreements"), with Dennis G. Ganster and with Codec Systems
Limited and Anthony Stafford. As of June 22, 2003, Dennis G. Ganster, Codec
Systems Limited and Anthony Stafford together have voting and dispositive
control over 1,572,752 Shares, representing approximately 15% of the outstanding
Shares. Pursuant to the Voting and Tender Agreements, Dennis G. Ganster, Codec
Systems Limited and Anthony Stafford have each agreed, among other things, to
tender all their Shares pursuant to the Offer and to vote their Shares in favor
of the Merger.

     Geac and the Company entered into a confidentiality agreement, dated as of
April 24, 2003 (the "Company Confidentiality Agreement"), pursuant to which Geac
agreed to keep confidential certain information provided by the Company. Geac
and the Company also entered into a confidentiality agreement, effective as of
May 1, 2003 (the "Geac Confidentiality Agreement" and together with the Company
Confidential Agreement, the "Confidentiality Agreements") pursuant to which the
Company agreed to keep confidential certain information provided by Geac.

     The Merger Agreement, Voting and Tender Agreements and Confidentiality
Agreements are more fully described in Section 12.

                                        9


     THE COMPANY BOARD HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT AND
THE TRANSACTIONS ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S
SHAREHOLDERS; HAS UNANIMOUSLY APPROVED AND ADOPTED THE MERGER AGREEMENT AND THE
TRANSACTIONS, INCLUDING THE OFFER AND MERGER, IN ACCORDANCE WITH THE
REQUIREMENTS OF MICHIGAN LAW; AND HAS AGREED TO RECOMMEND THAT THE COMPANY'S
SHAREHOLDERS ACCEPT THE OFFER, AND APPROVE AND ADOPT THE MERGER AGREEMENT AND
THE MERGER.

     Bryant Park Capital, Inc. ("Bryant Park Capital"), the Company's financial
advisor, has delivered to the Company Board its written opinion dated June 22,
2003, the date of the Merger Agreement, to the effect that, as of the date of
the opinion and based upon and subject to certain matters stated in such
opinion, the $4.60 net per Share cash consideration to be received in the Offer
and the Merger, taken together, by holders of Shares (other than Geac and its
affiliates) was fair, from a financial point of view, to such holders.

     A copy of the opinion of Bryant Park Capital is attached to the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which has been filed with the SEC and will be mailed with this document. HOLDERS
OF SHARES ARE ENCOURAGED TO READ THE OPINION CAREFULLY AND IN ITS ENTIRETY FOR A
DESCRIPTION OF THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND
LIMITATIONS OF THE REVIEW UNDERTAKEN BY BRYANT PARK CAPITAL IN CONNECTION WITH
SUCH OPINION.

     The Offer is conditioned upon, among other things, there being validly
tendered and not properly withdrawn prior to the expiration date (as defined in
Section 1 below) that number of Shares which, together with any other Shares
then owned by Geac, Purchaser or any affiliate of Geac or Purchaser on the date
such Shares are purchased, constitutes at least a majority of the total
outstanding shares of Comshare, calculated on a fully diluted basis after giving
effect to the exercise, conversion or termination of all options, warrants,
rights and securities exercisable or convertible into Shares, on the date of
purchase (the "Minimum Condition"). The Offer also is subject to certain other
conditions. See Section 15.

     Pursuant to the Merger Agreement, the Company granted to Purchaser an
irrevocable option (the "Top-Up Option") to purchase, at a purchase price per
Share issued pursuant to the Top-Up Option equal to the Offer Price, up to that
number of Shares equal to the lowest number of Shares that, when added to the
number of Shares owned by the Purchaser at the time of such exercise, will
constitute one share more than 90% of the Shares then outstanding on a fully
diluted basis (assuming the issuance of the Shares pursuant to the Top-Up Option
and the exercise of all outstanding exercisable options to purchase Shares with
an exercise price less than the Offer Price). See Section 12.

     The Company has informed us that, as of June 30, 2003, there were (a)
10,827,583 Shares issued and outstanding, and (b) 1,352,163 Shares reserved for
issuance upon the exercise of outstanding stock options. As a result, as of such
date, the number of Shares that must be validly tendered and not properly
withdrawn prior to the Expiration Date in order to satisfy the Minimum Condition
is 6,089,874. Certain other conditions to the consummation of the Offer are
described in Section 15. Subject to the terms of the Merger Agreement, we
expressly reserve the right to waive any one or more of the conditions to the
Offer. Pursuant to the Merger Agreement, we have agreed not to waive the Minimum
Condition without the consent of the Company. See Sections 12 and 15.

     The Merger Agreement provides that, effective upon the acceptance for
payment by us pursuant to the Offer of a number of Shares that satisfies the
Minimum Condition, we will be entitled to designate such number of directors,
rounded up to the nearest whole number, on the Company Board as is equal to the
product of the total number of directors on the Company Board (giving effect to
the directors to be elected as described in this sentence) multiplied by the
percentage that the number of Shares beneficially owned by us (including Shares
so accepted for payment) or any of our affiliates bears to the total number of
Shares then outstanding. The Company has agreed to take all action necessary to
cause our designees to be elected or appointed to the Company Board, including
increasing the number of directors on the Company Board. See Section 12.

     The completion of the Merger is subject to the satisfaction or waiver of a
number of conditions, including, if required, the approval of the Merger by the
requisite vote or consent of the shareholders. In order to approve the Merger,
the Company's Articles of Incorporation require the affirmative vote of holders
of a majority of

                                        10


the total voting power of all outstanding Shares. As a result, if the Minimum
Condition and the other conditions to the Offer are satisfied and the Offer is
consummated, we will own a sufficient number of Shares to ensure that the Merger
will be approved. Under Michigan law, if after consummation of the Offer we own
at least 90% of the Shares then outstanding, we will be able to cause the Merger
to occur without a vote of the Company's shareholders. See Section 12. If we
acquire less than this number of Shares, a vote of the Company's shareholders or
action by written consent will be required under Michigan law to approve the
Merger, the Company will be required in connection therewith to circulate a
proxy statement or information statement conforming to the requirements of
applicable regulations of the SEC and, consequently, a significantly longer
period of time will be required to effect the Merger than if no vote were
required.

     Certain U.S. federal income tax consequences of the sale of Shares in the
Offer and the Merger are described in Section 5.

     THE OFFER IS CONDITIONED UPON THE FULFILLMENT OF THE CONDITIONS DESCRIBED
IN SECTION 15 BELOW. THE OFFER WILL EXPIRE AT 12:00 MIDNIGHT, EASTERN TIME, ON
WEDNESDAY, JULY 30, 2003, UNLESS WE EXTEND IT.

     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH YOU SHOULD READ CAREFULLY BEFORE YOU MAKE ANY
DECISION WITH RESPECT TO THE OFFER.

                                        11


                                   THE OFFER

1.  TERMS OF THE OFFER; EXPIRATION DATE

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any extension or
amendment), we will purchase all Shares validly tendered and not properly
withdrawn in accordance with the procedures set forth in Section 4 of this Offer
to Purchase on or prior to the Expiration Date. The term "Expiration Date" means
12:00 midnight, Eastern time, on July 30, 2003, unless and until we, in
accordance with the terms of the Offer, extend the period of time for which the
Offer is open, in which event the term "Expiration Date" means the time and date
at which the Offer, as so extended, will expire.

     We expressly reserve the right to waive the Minimum Condition or any of the
other conditions to the Offer and to make any change in the terms or conditions
of the Offer. However, in the Merger Agreement, we have agreed that, without the
prior written consent of the Company, we will not make any changes that would
(a) waive the Minimum Condition, (b) change the form of consideration payable in
the Offer, (c) decrease the price per Share or the number of Shares sought in
the Offer, (d) impose conditions to the Offer in addition to those set forth in
the Merger Agreement or that would otherwise be adverse to the holders of the
Shares or (e) waive the condition that by the Determination Time (as defined in
the Merger Agreement) any applicable waiting period under the HSR Act or any
laws, rules or regulations analogous to the HSR Act existing in foreign
jurisdictions has expired or been terminated.

     Subject to the applicable regulations of the SEC and the terms of the
Merger Agreement, we also reserve the right to extend the Offer beyond the
initial expiration date in the following events: (a) from time to time, but not
later than October 1, 2003, if, at the initial expiration date, one or more of
the conditions to the Offer (other than the Minimum Condition) shall not have
been satisfied or waived, until such conditions are satisfied or waived, (b) for
any period required by any rule, regulation, interpretation or position of the
SEC or as otherwise required by applicable law or (c) if all conditions to the
Offer are satisfied or waived but the number of Shares validly tendered and not
withdrawn is less than ninety percent of the then outstanding number of Shares.
We acknowledge (a) that Rule 14e-1(c) under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), requires us to pay the consideration offered or
return the Shares tendered promptly after the termination or withdrawal of the
Offer and (b) that we may not delay purchase of, or payment for (except as is
required in order to comply with applicable laws), any Shares upon the
occurrence of any event specified in Section 15 without extending the period of
time during which the Offer is open.

     The rights we reserve in the preceding paragraphs are in addition to our
rights pursuant to Section 15 of this Offer to Purchase. Any extension, delay,
termination or amendment of the Offer or waiver of conditions of the Offer will
be followed as promptly as practicable by a public announcement. An
announcement, in the case of an extension, will be made no later than 9:00 a.m.,
Eastern time, on the next business day after the previously scheduled Expiration
Date. Without limiting the manner in which we may choose to make any public
announcement, subject to applicable law (including Rules 14d-4(d) and 14d-6(c)
promulgated under the Exchange Act, which require that material changes be
promptly disseminated to holders of Shares), we will have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by issuing a release to the Dow Jones News Service.

     If we extend the Offer, are delayed in our payment for Shares (after our
acceptance of Shares for payment) or are unable to pay for Shares for any
reason, then, without prejudice to our rights under the Offer, the Depositary
may retain tendered Shares on our behalf and such Shares may not be withdrawn,
except to the extent that tendering shareholders are entitled to withdrawal
rights as described in Section 4 of this Offer to Purchase. Our ability to delay
the payment for Shares that we have accepted for payment is limited, however, by
Rule 14e-1(c) promulgated under the Exchange Act, which requires that we pay the
consideration offered or return the Shares deposited by or on behalf of
shareholders promptly after the termination or withdrawal of the Offer, unless
we include a Subsequent Offering Period under Rule 14d-11 promulgated under the
Exchange Act and pay for Shares tendered during the Subsequent Offering Period
in accordance with that rule and the terms of the Merger Agreement.

                                        12


     If we make a material change in the terms of the Offer, or if we waive a
material condition to the Offer, we will extend the Offer and disseminate
additional tender offer materials to the extent required by Rules 14d-4(d),
14d-6(c) and 14e-1 promulgated under the Exchange Act. The minimum period during
which a tender offer must remain open following material changes in the terms of
the Offer, other than a change in price or a change in percentage of securities
sought, depends upon the facts and circumstances, including the materiality of
the changes. In the SEC's view, an offer should remain open for a minimum of
five business days from the date the material change is first published, sent or
given to shareholders, and, if material changes are made with respect to
information that approaches in significance the terms of the Offer relating to
price and the percentage of securities sought, a minimum of ten business days
may be required to allow for adequate dissemination and investor response. With
respect to a change of price, a minimum ten business day period from the date of
the change is generally required to allow for adequate dissemination to
shareholders. Accordingly, if, prior to the Expiration Date (and to the extent
we are permitted to do so under the Merger Agreement), we decrease the number of
Shares being sought, or increase or decrease the consideration offered pursuant
to the Offer, and if the Offer is scheduled to expire at any time earlier than
the period ending on the tenth business day from the date that notice of the
increase or decrease is first published, sent or given to holders of Shares, we
will extend the Offer at least until the expiration of that period of ten
business days. For purposes of the Offer, a "business day" means any day other
than a Saturday, Sunday or a U.S. federal holiday and consists of the time
period from 12:01 a.m. through 12:00 midnight, Eastern time.

     The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition. Consummation of the Offer is also conditioned upon expiration
or termination of all waiting periods imposed by the HSR Act and any laws, rules
or regulations analogous to the HSR Act existing in foreign jurisdictions, and
the other conditions set forth in Section 15. We reserve the right (but are not
obligated), in accordance with applicable rules and regulations of the SEC and
with the Merger Agreement, to waive any or all of those conditions. If, by the
Expiration Date, any or all of those conditions have not been satisfied, we may,
without the consent of the Company, elect to (a) waive all of the unsatisfied
conditions (other than the Minimum Condition and the condition relating to the
HSR Act) and, subject to complying with applicable rules and regulations of the
SEC, accept for payment all Shares so tendered; or (b) subject to the terms of
the Merger Agreement, terminate the Offer and not accept for payment any Shares
and return all tendered Shares to tendering shareholders. In the event that we
waive any condition set forth in Section 15, the SEC may, if the waiver is
deemed to constitute a material change to the information previously provided to
the shareholders, require that the Offer remain open for an additional period of
time and/or that we disseminate information concerning such waiver.

     The Merger Agreement also gives us the right to extend the initial
Expiration Date, without the consent of the Company, in the following events:
(i) from time to time, but in no event to a date later than October 1, 2003, if,
at the initial Expiration Date (or extended Expiration Date of the Offer, if
applicable), one or more of the conditions to the Offer (other than the Minimum
Condition) shall not have been satisfied or waived, until such conditions are
satisfied or waived; (ii) for any period required by any SEC rule, regulation,
interpretation or position applicable to the Offer or any period required by
applicable United States law, or (iii) if all of the conditions to the Offer are
satisfied or waived but the number of Shares validly tendered and not withdrawn
is less than ninety percent (90%) of the outstanding number of Shares, for a
subsequent offering period (a "Subsequent Offering Period") consistent with Rule
14d-11 of the Exchange Act; provided that the Expiration Date of the Offer may
not extend beyond 12:00 midnight, Eastern time, on October 1, 2003; and provided
further, that, in the case of any such Subsequent Offering Period, we (x) accept
and pay for Shares validly tendered and not withdrawn, as soon as reasonably
practical prior to the date of such extension, (y) otherwise meet the
requirements of Rule 14d-11 under the Exchange Act in connection with such
Subsequent Offering Period and (z) waive any condition to the consummation of
the Merger other than the requirement that there be no statute, rule or
regulation by any governmental entity or an injunction by a court of competent
jurisdiction which prevents the consummation of the Merger. In addition, we have
agreed that, if requested by the Company, we will (a) extend the Offer if, at
the Expiration Date, no conditions to the Offer (other than the conditions
relating to suits, actions or proceedings or applicable statutes, rules,
regulations or injunctions) then excuse performance by us, for up to 20 business
days after such previously scheduled Expiration Date, or (b) provide a
Subsequent Offering Period if there are validly tendered Shares then owned
                                        13


by Geac representing at least eighty percent (80%), but not more than ninety
percent (90%), of the Shares outstanding. Upon the satisfaction or waiver of all
the conditions to the Offer and subject to the terms of the Merger Agreement, we
will accept for payment, purchase and pay for, in accordance with the terms of
the Offer, all Shares validly tendered and not withdrawn pursuant to the Offer
as soon as reasonably practicable after the expiration of the Offer.

     In order to provide a Subsequent Offering Period, we must satisfy the
following conditions:

     - the Offer was open for a minimum of 20 business days and has expired;

     - we accept and promptly pay for all Shares tendered during the initial
       Offer period;

     - we announce the results of the Offer, including the approximate number
       and percentage of Shares tendered, no later than 9:00 a.m., Eastern time,
       on the next business day after the Expiration Date and immediately begin
       the Subsequent Offering Period;

     - we immediately accept and promptly pay for Shares as they are tendered
       during the Subsequent Offering Period; and

     - we pay the same form and amount of consideration for all Shares tendered
       during the Subsequent Offering Period.

     A Subsequent Offering Period, if one is provided, is not an extension of
the Offer. A Subsequent Offering Period would be an additional period of time,
following the expiration of the Offer, in which shareholders may tender Shares
not tendered during the Offer.

     Pursuant to Rule 14d-7 promulgated under the Exchange Act, no withdrawal
rights will apply to Shares tendered in a Subsequent Offering Period and no
withdrawal rights apply during the Subsequent Offering Period with respect to
Shares tendered in the Offer and accepted for payment. The same consideration,
the Offer Price, will be paid to shareholders tendering Shares in the Offer or
in a Subsequent Offering Period, if one is provided.

     The Company has provided us with its shareholder lists and security
position listings for the purpose of disseminating the Offer to holders of
Shares. We will mail this Offer to Purchase, the related Letter of Transmittal
and other relevant materials to record holders of Shares and we will furnish the
materials to brokers, dealers, banks and similar persons whose names, or the
names of whose nominees, appear on the shareholder lists or, if applicable, who
are listed as participants in a clearing agency's security position listing, for
forwarding to beneficial owners of Shares.

2.  ACCEPTANCE FOR PAYMENT AND PAYMENT

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of the Offer as so
extended or amended), we will purchase, by accepting for payment, and will pay
for all Shares validly tendered and not properly withdrawn prior to the
Expiration Date (as permitted by Section 4) promptly after the later to occur of
(i) the Expiration Date and (ii) subject to compliance with the applicable rules
and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act, the
satisfaction or waiver of the conditions to the Offer set forth in Section 15.
In addition, subject to applicable rules of the SEC, we reserve the right to
delay acceptance for payment of, or payment for, Shares pending receipt of any
regulatory or governmental approvals specified in Section 16.

     For information with respect to regulatory approvals that we are required
to obtain prior to the completion of the Offer, see Section 16.

     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) certificates for
such Shares (or a timely Book-Entry Confirmation (as defined below in Section 3)
with respect thereto), (ii) the Letter of Transmittal, properly completed and
duly executed, with any required signature guarantees, or, in the case of a
book-entry transfer, an Agent's Message (as defined below), and (iii) any other
documents required by the Letter of Transmittal.

                                        14


     The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility (as defined below in Section 3) to, and received by, the
Depositary and forming a part of a Book-Entry Confirmation, which states that
such Book-Entry Transfer Facility has received an express acknowledgment from
the participant in such Book-Entry Transfer Facility tendering the Shares that
such participant has received and agrees to be bound by the terms of the Letter
of Transmittal and that we may enforce such agreement against the participant.

     For purposes of the Offer, we will be deemed to have accepted for payment,
and thereby purchased, Shares properly tendered to us and not properly
withdrawn, if and when we give written notice to the Depositary of our
acceptance for payment of such Shares. Payment for Shares accepted for payment
pursuant to the Offer will be made by deposit of the Offer Price therefor with
the Depositary, which will act as agent for tendering shareholders for the
purpose of receiving payment from us and transmitting payment to tendering
shareholders. Upon the deposit of funds with the Depositary for the purpose of
making payments to tendering shareholders, our obligation to make such payment
shall be satisfied, and tendering shareholders must thereafter look solely to
the Depositary for payment of amounts owed to them by reason of the acceptance
for payment of Shares pursuant to the Offer.

     UNDER NO CIRCUMSTANCES WILL WE PAY INTEREST ON THE OFFER PRICE FOR SHARES,
REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

     If we are delayed in our acceptance for payment of, or payment for, Shares
or are unable to accept for payment, or pay for, Shares pursuant to the Offer
for any reason, then, without prejudice to our rights under the Offer (but
subject to compliance with Rule 14e-1(c) under the Exchange Act), the Depositary
may, nevertheless, on our behalf, retain tendered Shares, and such Shares may
not be withdrawn except to the extent tendering shareholders are entitled to
exercise, and duly exercise, withdrawal rights as described in Section 4.

     If any tendered Shares are not accepted for payment pursuant to the Offer
for any reason, or if certificates are submitted representing more Shares than
are tendered, certificates representing Shares not tendered or not accepted for
purchase will be returned to the tendering shareholder, or such other person as
the tendering shareholder shall specify in the Letter of Transmittal, as
promptly as practicable following the expiration, termination or withdrawal of
the Offer. In the case of Shares delivered by book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility pursuant to the
procedures set forth in Section 3, such Shares will be credited to such account
maintained at the Book-Entry Transfer Facility as the tendering shareholder
shall specify in the Letter of Transmittal, as promptly as practicable following
the expiration, termination or withdrawal of the Offer. If no such instructions
are given with respect to Shares delivered by book-entry transfer, any such
Shares not tendered or not purchased will be returned by crediting the account
at the Book-Entry Transfer Facility designated in the Letter of Transmittal as
the account from which such Shares were delivered.

     The Company will pay any transfer taxes payable on the transfer to it of
Shares purchased pursuant to the Offer, provided, however, that if (a) payment
of the Purchase Price is to be made to, or (in the circumstances permitted by
the Offer) unpurchased Shares are to be registered in the name(s) of, any
person(s) other than the registered owner(s), or (b) if any tendered
certificate(s) are registered, or the Shares tendered are otherwise held, in the
name(s) of any person(s) other than the registered owner, the amount of any
transfer taxes (whether imposed on the registered owner(s) or such other
person(s)) payable on account of such transactions will be deducted from the
Purchase Price unless satisfactory evidence of the payment of such taxes, or
exemption therefrom, is submitted with the Letter of Transmittal.

     IF, PRIOR TO THE EXPIRATION DATE, WE INCREASE THE PRICE OFFERED TO HOLDERS
OF SHARES IN THE OFFER, WE WILL PAY THE INCREASED PRICE TO THE HOLDERS OF ALL
SHARES THAT WE PURCHASE IN THE OFFER, WHETHER THE SHARES WERE TENDERED BEFORE OR
AFTER THE INCREASE IN PRICE.

     We reserve the right to transfer or assign, in whole or from time to time
in part, to Geac, or any of our affiliates, the right to purchase all or any
portion of the Shares tendered in the Offer, but any such transfer or assignment
will not relieve us of our obligations under the Offer or prejudice your rights
to receive payment for

                                        15


Shares validly tendered and accepted for payment in the Offer. However, we have
no present intention to effect such transfer.

3.  PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES

  VALID TENDER OF SHARES

     Except as set forth below, for Shares to be validly tendered pursuant to
the Offer, either (i) a properly completed and duly executed Letter of
Transmittal, together with any required signature guarantees, or in the case of
a book-entry transfer, an Agent's Message, and any other required documents,
must be received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date and either
certificates for tendered Shares must be received by the Depositary at one of
such addresses or such Shares must be delivered pursuant to the procedures for
book-entry transfer set forth below (and a Book-Entry Confirmation (as defined
below) received by the Depositary), in each case prior to the Expiration Date,
or (ii) the tendering shareholder must comply with the guaranteed delivery
procedures set forth below.

     THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH A BOOK-ENTRY TRANSFER FACILITY,
IS AT THE ELECTION AND RISK OF THE TENDERING SHAREHOLDER. SHARES WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE
OF BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

     If your Shares are registered in the name of a broker, dealer, commercial
bank, trust company or other nominee, you should contact that person if you
desire to tender your Shares.

  BOOK-ENTRY TRANSFER

     The Depositary will establish an account with respect to the Shares at The
Depositary Trust Company (the "Book-Entry Transfer Facility") for purposes of
the Offer within two (2) business days after the date of this Offer to Purchase.
Any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Shares by causing the
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account in accordance with the Book-Entry Transfer Facility's procedure for such
transfer. However, although delivery of Shares may be effected through
book-entry transfer into the Depositary's account at the Book-Entry Transfer
Facility, the Letter of Transmittal, properly completed and duly executed, with
any required signature guarantees, or an Agent's Message, and any other required
documents must, in any case, be delivered to, and received by, the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase prior
to the Expiration Date, or the tendering shareholder must comply with the
guaranteed delivery procedures described below. The confirmation of a book-entry
transfer of Shares into the Depositary's account at the Book-Entry Transfer
Facility as described above is referred to herein as a "Book-Entry
Confirmation."

     REQUIRED DOCUMENTS MUST BE DELIVERED TO AND RECEIVED BY THE DEPOSITARY AT
ONE OF ITS ADDRESSES SET FORTH ON THE BACK COVER PAGE OF THIS OFFER TO PURCHASE.
DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH THE
BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE
DEPOSITARY.

  SIGNATURE GUARANTEES

     No signature guarantee is required on the Letter of Transmittal (i) if the
Letter of Transmittal is signed by the registered holder(s) (which term, for
purposes of this Section, includes any participant in the Book-Entry Transfer
Facility's systems whose name appears on a security position listing as the
owner of the Shares tendered therewith) and such registered holder has not
completed either the box entitled "Special Delivery Instructions" or the box
entitled "Special Payment Instructions" on the Letter of Transmittal or (ii) if
such Shares are tendered for the account of a financial institution (including
most commercial banks, savings and loan associations and brokerage houses) that
is a participant in the Security Transfer Agents Medallion

                                        16


Program, the New York Stock Exchange Medallion Signature Guarantee Program or
the Stock Exchange Medallion Program (each, an "Eligible Institution" and,
collectively, "Eligible Institutions"). In all other cases, all signatures on
Letters of Transmittal must be guaranteed by an Eligible Institution. See
Instructions 1 and 6 to the Letter of Transmittal. If the certificates for
Shares are registered in the name of a person other than the signer of the
Letter of Transmittal, or if payment is to be made, certificates for Shares not
tendered or not accepted for payment are to be returned, to a person other than
the registered holder of the certificates surrendered, then the tendered
certificates for such Shares must be endorsed or accompanied by appropriate
stock powers, in either case, signed exactly as the name or names of the
registered holders or owners appear on the certificates, with the signatures on
the certificates or stock powers guaranteed as aforesaid. See Instruction 6 to
the Letter of Transmittal.

  GUARANTEED DELIVERY

     If you want to tender your Shares pursuant to the Offer and your
certificates are not immediately available or the procedures for book-entry
transfer cannot be completed on a timely basis or time will not permit all
required documents to reach the Depositary prior to the Expiration Date, your
tender may be effected if all the following conditions are met:

     - such tender is made by or through an Eligible Institution;

     - a properly completed and duly executed Notice of Guaranteed Delivery,
       substantially in the form provided by us, is received by the Depositary,
       as provided below, prior to the Expiration Date; and

     - the certificates for (or a Book-Entry Confirmation with respect to) such
       Shares, together with a properly completed and duly executed Letter of
       Transmittal, with any required signature guarantees, or, in the case of a
       book-entry transfer, an Agent's Message, and any other required
       documents, are received by the Depositary within three trading days after
       the date of execution of such Notice of Guaranteed Delivery. A "trading
       day" is any day on which the Nasdaq Stock Market is open for business.

     The Notice of Guaranteed Delivery may be delivered by hand to the
Depositary or transmitted by mail to the Depositary at one of its addresses set
forth on the back cover page of this Offer to Purchase and must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery distributed with this Offer to Purchase.

     Notwithstanding any other provision of the Offer, we will pay for Shares
only after timely receipt by the Depositary of certificates for, or of
Book-Entry Confirmation with respect to, the Shares, a properly completed and
duly executed Letter of Transmittal, together with any required signature
guarantees (or, in the case of a book-entry transfer, an Agent's Message), and
any other documents required by the Letter of Transmittal.

     Accordingly, payment might not be made to all tendering shareholders at the
same time, and will depend upon when the Depositary receives certificates or
Book-Entry Confirmation that the Shares have been transferred into the
Depositary's account at the Book-Entry Transfer Facility.

  BACKUP FEDERAL TAX WITHHOLDING

     If you are a U.S. person, the Depositary will withhold United States
federal income taxes at a rate of 30% of the gross payment payable to you,
unless you complete and sign the Substitute Form W-9 included as part of the
Letter of Transmittal, and provide the information and certification necessary
to avoid backup withholding. Under the U.S. federal backup withholding tax
rules, 30% of the gross proceeds payable to a U.S. person (such as a U.S.
citizen or resident alien) under the tender offer generally must be withheld and
remitted to the United States Treasury unless the U.S. person has provided the
Depositary with a taxpayer identification number ("TIN," usually an employer
identification number or a social security number) and certified under penalties
of perjury that the TIN is correct and that the U.S. person is not otherwise
subject to backup withholding. If, in making such a certification, you fail to
furnish the correct TIN or make other false statements, you may be subject to
certain penalties specified in the Internal Revenue Code of 1986, as amended
(the "Code"). Certain shareholders are exempted from the backup withholding and
reporting
                                        17


requirements rules. For additional discussion of U.S. federal income tax
consequences to tendering Shareholders, see Section 5.

  FEDERAL INCOME TAX WITHHOLDING ON FOREIGN SHAREHOLDERS

     If you are a foreign shareholder or an agent for a foreign shareholder, the
Depositary will withhold United States federal income taxes at a rate of 30% of
the gross payment payable to you, unless the Depositary determines that an
exemption from, or a reduced rate of, withholding tax is applicable because this
income is exempt from U.S. taxation, because a tax treaty that applies to you
provides for a different withholding rate, because you are exempt from U.S.
withholding, or because such gross payment is effectively connected with the
conduct of a trade or business by you within the United States. The Depositary
must receive certain supporting documentation as follows:

     -  If you are a fiscally-transparent intermediary for non-U.S. persons,
        before the payment you must deliver to the Depositary a properly
        completed and executed Form W-8IMY or other equivalent form;

     -  If you are a non-U.S. person claiming an exemption from withholding on
        the grounds that the gross proceeds paid under the tender offer are
        effectively connected with the conduct of a trade or business by you
        within the U.S., before the payment you must deliver to the Depositary a
        properly completed and executed Form W-8ECI or other equivalent form;

     -  If you are a non-U.S. person otherwise claiming an exemption from, or a
        reduced rate of, withholding, before the payment you must deliver to the
        Depositary a properly completed and executed Form W-8EXP, Form W-8BEN or
        other equivalent form; and

     -  If you are a non-U.S. person who is the beneficial owner of the Shares,
        and you are not claiming exemption from, or a reduced rate of,
        withholding as described above, then before the payment you must deliver
        to the Depositary a properly completed and executed Form W-8BEN or other
        equivalent form.

     A foreign Shareholder may be eligible for a refund of all or a portion of
any tax that is withheld if the Shareholder is entitled to the benefits of a
reduced rate of withholding pursuant to a treaty but a higher rate has been
withheld or if the Shareholder is otherwise able to establish that no tax or a
reduced rate of tax is actually due.

     FOREIGN SHAREHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE
APPLICATION OF U.S. FEDERAL INCOME TAX WITHHOLDING, INCLUDING ELIGIBILITY FOR A
REDUCTION OF OR AN EXEMPTION FROM WITHHOLDING TAX.

  APPOINTMENT AS PROXY

     By executing the Letter of Transmittal, you irrevocably appoint our
designees, and each of them, as your agents, attorneys-in-fact and proxies, with
full power of substitution, in the manner set forth in the Letter of
Transmittal, to the full extent of your rights with respect to the Shares that
you tender and that we accept for payment and with respect to any and all other
Shares and other securities or rights issued or issuable in respect of such
Shares on or after the date of this Offer to Purchase. All such powers of
attorney and proxies will be considered irrevocable and coupled with an interest
in the tendered Shares. This appointment will be effective when we accept your
Shares for payment in accordance with the terms of the Offer. Upon such
acceptance for payment, all other powers of attorney and proxies given by you
with respect to your Shares and such other securities or rights granted prior to
such payment will be revoked, without further action, and no subsequent powers
of attorney and proxies may be given by you (and, if given, will not be deemed
effective). Our designees will, with respect to the Shares and such other
securities and rights for which the appointment is effective, be empowered to
exercise all your voting and other rights as they in their sole discretion may
deem proper at any annual or special meeting of the Company's shareholders, or
any adjournment or postponement thereof, or by consent in lieu of any such
meeting. In order for Shares to be deemed validly tendered, immediately upon the
acceptance for payment of such Shares, we or our designee must be able to
exercise full voting, consent and other rights with respect to such Shares and
other securities, including voting at any meeting of shareholders.
                                        18


  DETERMINATION OF VALIDITY

     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of any tender of Shares will be determined by us, in our
sole discretion, which determination will be final and binding. We reserve the
absolute right to reject any or all tenders of any Shares determined by us not
to be in proper form or the acceptance for payment of which, or payment for
which, may be unlawful. We also reserve the absolute right, in our sole
discretion, to waive any of the conditions of the Offer or any defect or
irregularity in the tender of any Shares of any particular Holder, whether or
not similar defects or irregularities are waived in the case of other Holders.
No tender of Shares will be deemed to have been validly made until all defects
or irregularities relating thereto have been cured or waived. None of Geac,
Purchaser, or any of their respective affiliates or assigns, if any, the
Depositary, the Information Agent, the Dealer Manager, or any other person will
be under any duty to give notification of any defects or irregularities in
tenders or incur any liability for failure to give any such notification. Our
interpretation of the terms and conditions of the Offer (including the Letter of
Transmittal and the instructions thereto) will be final and binding.

  LOST OR DESTROYED CERTIFICATES

     Holders of Shares whose certificates for part or all of their Shares have
been lost, stolen, misplaced or destroyed should contact the transfer agent for
Comshare common stock, Computershare Trust Company of New York, at (312)
360-5223. The shareholder will then be instructed by Computershare Trust Company
of New York as to the steps that must be taken in order to replace such
certificate. That certificate will then be required to be submitted together
with the Letter of Transmittal in order to receive payment for Shares that are
tendered and accepted for payment. A bond will be required to be posted by the
Holder to secure against the risk that the certificates may be subsequently
recirculated. Holders of Shares are urged to contact Computershare Trust Company
of New York immediately in order to permit timely processing of this
documentation. Certificates, together with a properly completed and duly
executed Letter of Transmittal, including any signature guarantees, or an
Agent's Message, and any other required documents must be delivered to the
Depositary and not to us, the Dealer Manager or the Information Agent. ANY SUCH
DOCUMENTS DELIVERED TO US, THE DEALER MANAGER OR THE INFORMATION AGENT WILL NOT
BE FORWARDED TO THE DEPOSITARY AND, THEREFORE, WILL NOT BE DEEMED TO BE PROPERLY
TENDERED.

  BINDING AGREEMENT

     The tender of Shares pursuant to any one of the procedures described above
will constitute the tendering shareholder's acceptance of the Offer, as well as
the tendering shareholder's representation and warranty that the shareholder has
the full power and authority to tender and assign the Shares tendered, as
specified in the Letter of Transmittal. Our acceptance for payment of Shares
tendered pursuant to the Offer will constitute a binding agreement between the
Purchaser and you upon the terms and subject to the conditions of the Offer.

4.  WITHDRAWAL RIGHTS

     Except as otherwise provided in this Section 4, tenders of Shares are
irrevocable. Shares tendered pursuant to the Offer may be withdrawn pursuant to
the procedures set forth below at any time prior to the Expiration Date and,
unless theretofore accepted for payment and paid for by us pursuant to the
Offer, may also be withdrawn at any time after August 30, 2003.

     For a withdrawal to be effective, a written notice of withdrawal must be
timely received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase and must specify the name of the person having
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the name of the registered holder of the Shares to be withdrawn, if different
from the name of the person who tendered the Shares.

     If certificates for Shares have been delivered or otherwise identified to
the Depositary, then, prior to the physical release of such certificates, the
serial numbers shown on such certificates must be submitted to the Depositary
and, unless such Shares have been tendered by an Eligible Institution, the
signatures on the notice of withdrawal must be guaranteed by an Eligible
Institution.
                                        19


     If Shares have been delivered pursuant to the procedures for book-entry
transfer as set forth in Section 3, any notice of withdrawal must also specify
the name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Shares and otherwise comply with such Book-Entry
Transfer Facility's procedures. Withdrawals of tenders of Shares may not be
rescinded, and any Shares properly withdrawn will thereafter be deemed not
validly tendered for purposes of the Offer. However, withdrawn Shares may be
tendered again following one of the procedures described in Section 3, any time
prior to the Expiration Date.

     If we extend the Offer, are delayed in our acceptance of Shares for payment
or are unable to accept Shares for payment for any reason, then, without
prejudice to our rights under the Offer, the Depositary may, nevertheless,
retain tendered Shares on our behalf, and such Shares may not be withdrawn
except to the extent that tendering Holders are entitled to withdraw them as
described in this Section 4. Any such delay will be accompanied by an extension
of the Offer to the extent required by law. All questions as to the form and
validity (including time of receipt) of notices of withdrawal will be determined
by us, in our sole discretion, which determination will be final and binding.
None of Geac, Purchaser, or any of their respective affiliates or assigns, if
any, the Depositary, the Information Agent, the Dealer Manager, or any other
person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.

     No withdrawal rights will apply to Shares tendered during any Subsequent
Offering Period and no withdrawal rights apply during any such Subsequent
Offering Period with respect to Shares tendered in the Offer and accepted for
payment.

5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following discussion applies to shareholders that are "U.S. persons"
for federal income tax purposes. The discussion does not address aspects of U.S.
taxation other than U.S. federal income taxation, nor does it address aspects of
U.S. federal income taxation that may apply to shareholders that are subject to
special rules under the Code, including, without limitation, rules that apply to
persons who acquired Shares as a result of the exercise of employee stock
options, tax-exempt organizations, financial institutions, broker-dealers,
insurance companies, persons who hold their shares as part of a straddle, wash
sale, hedging or conversion transaction, foreign persons, or pass-through
entities. In addition, this discussion does not address state, local or foreign
taxation.

     Your receipt of cash in exchange for Shares pursuant to the Offer or the
Merger will be taxable for U.S. federal income tax purposes and may also be
taxable under applicable state, local or foreign tax laws. Upon your receipt of
cash, you will recognize gain or loss for U.S. federal income tax purposes in an
amount equal to the difference, if any, between the amount of cash you receive
and your adjusted tax basis in the Shares you sell or exchange pursuant to the
Offer or Merger. Gain or loss must be determined separately for each block of
Shares exchanged (for example, Shares acquired at the same cost in a single
transaction). Such gain or loss will be capital gain or loss (if you hold your
Shares as a capital asset) and any such capital gain or loss will be long term
if, as of the date of the sale or exchange, you have held the Shares for more
than one year.

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE
PARTICULAR TAX CONSEQUENCES TO YOU OF THE OFFER AND THE MERGER, INCLUDING
FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES.

FOR THE COMMON STOCK.

7.  EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; NASDAQ LISTING; EXCHANGE
    ACT REGISTRATION

  EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES

     The purchase of Shares pursuant to the Offer will reduce the number of
Shares that might otherwise trade publicly and could adversely affect the
liquidity and market value of the remaining Shares held by the public. The
purchase of Shares pursuant to the Offer also can be expected to reduce the
number of holders of Shares. We cannot predict whether the reduction in the
number of Shares that might otherwise trade publicly would have an adverse or
beneficial effect on the market price for or marketability of the Shares or
whether it would cause future market prices to be greater or less than the Offer
Price.

  NASDAQ LISTING

     Depending upon the number of Shares acquired pursuant to the Offer, the
Shares may no longer meet the requirements for continued listing on Nasdaq.
According to Nasdaq's published guidelines, Nasdaq would consider delisting an
issuer's shares if, among other things: (a) the number of the issuer's
outstanding shares (with certain exclusions) falls below 750,000, (b) the market
value of such shares publicly held falls below $5,000,000, (c) the issuer has
shareholder equity of less than $10,000,000, (d) there are fewer than 400
holders of round lots of the issuer's shares, and (e) the minimum bid price
falls below $1.00 per share. If, as a result of the purchase of Shares pursuant
to the Offer or otherwise, the Shares no longer meet the requirements of Nasdaq
for continued listing and/or trading and such trading of the Shares were
discontinued, the market for the Shares could be adversely affected.

     In the event that the Shares were no longer listed or traded on Nasdaq, it
is possible that the Shares would trade in the over-the-counter market and that
price quotations would be reported through Nasdaq or other sources. Such trading
and the availability of such quotations would, however, depend upon the number
of shareholders and/or the aggregate market value of the Shares remaining at
such time, the interest in maintaining a market in the Shares on the part of
securities firms, the possible termination of registration of the Shares under
the Exchange Act as described below and other factors.

                                        21


  EXCHANGE ACT REGISTRATION

     The Shares are currently registered under the Exchange Act. The purchase of
the Shares pursuant to the Offer may result in the Shares becoming eligible for
deregistration under the Exchange Act. Registration of the Shares may be
terminated upon application by the Company to the SEC if the Shares are not
listed on a "national securities exchange" and there are fewer than 300 record
holders of Shares. Termination of registration of the Shares under the Exchange
Act would substantially reduce the information required to be furnished by the
Company to its shareholders and the SEC and would make certain provisions of the
Exchange Act, such as the short-swing profit recovery provisions of Section
16(b) and the requirements of furnishing a proxy statement in connection with
shareholder meetings pursuant to Section 14(a), no longer applicable to the
Company. If the Shares are no longer registered under the Exchange Act, the
requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions would no longer be applicable to the Company. Furthermore,
the ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144
promulgated under the Securities Act of 1933, as amended (the "Securities Act"),
may be impaired or eliminated. If, as a result of the purchase of Shares
pursuant to the Offer or the proposed Merger, the Company is no longer required
to maintain registration of the Shares under the Exchange Act, we intend to
cause the Company to apply for termination of such registration.

     If registration of the Shares is not terminated prior to the Merger, then
the Shares will be delisted from the Nasdaq Stock Market and the registration of
the Shares under the Exchange Act will be terminated promptly following the
consummation of the Merger.

10.  BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY

     In November 2002, the Company's executive management and Board of Directors
met and discussed the possibility that the Company's prospects for improved
shareholder value might be enhanced by exploring strategic alternatives. The
Company's legal counsel reviewed for the Board the fiduciary duties of the
Company's Board when considering strategic alternatives for the Company. On
November 22, 2002, the Company engaged Bryant Park Capital, Inc. ("Bryant Park
Capital") to act as the Company's exclusive financial advisor in connection with
evaluating the Company's strategic alternatives.

     Beginning in December 2002, the Company approached various parties about
the possibility of acquiring the Company. In January 2003, the Company prepared
a Confidential Informational Memorandum (the "Confidential Memorandum"), which
contained a brief description of the Company's business, as well as certain
financial information. During 2003, the Company signed confidentiality
agreements with a number of parties, providing them with access to the
Confidential Memorandum and additional information about the Company, and
provided them the ability to meet with management. Representatives of Bryant
Park Capital and Richard Crandall, a director of the Company, acting on behalf
of the Company, discussed a potential transaction with these parties. Seven
parties commenced due diligence investigations of the Company and had meetings
with members of the Company's management, including Dennis Ganster, Chairman,
President and Chief Executive Officer; Brian Hartlen, Senior Vice President,
Marketing; David King, Senior Vice President, Product Development and Chief
Technology Officer; Kenneth Kane, Senior Vice President, Direct Operations; and
Brian Jarzynski, Senior Vice President and Chief Financial Officer. On February
14, 2003, the Board held a regularly scheduled meeting. Among the matters
covered was the status of discussions with parties potentially interested in
engaging in a transaction with the Company. By mid-March 2003, there were three
parties interested in discussing further the possible acquisition of the
Company. Over the course of the next month, the Company engaged in continuing
discussions and due diligence activities with these and other potentially
interested parties. On March 31, 2003, the Board met to discuss the status of
discussions with interested parties.

     On April 1, 2003, a member of the Company's Board of Directors and a member
of Geac's board of directors discussed Geac's interest in a potential
transaction with the Company. On April 14, 2003, Mr. Crandall and William
Nelson, a member of the board of directors of Geac, discussed the nature of
Geac's interest in the Company. As a result of that contact, Charles S. Jones,
Executive Chairman of Geac, contacted Mr. Crandall on April 21, 2003 to discuss
a potential acquisition of the Company. On April 24, 2003, Geac and the Company
entered into a confidentiality agreement, and Bryant Park Capital, at the
Company's request, provided Geac with the Confidential Memorandum and additional
information about the Company. On April 25, 28 and 29, and May 2, 2003, members
of the management of Geac, including Mr. Jones; Paul Birch, President and Chief
Executive Officer; Tim Wright, Chief Technology Officer; Jay Sherry, Senior Vice
President, Marketing and Strategic Alliances; and Joyce Koenig, Vice President,
Strategic Financial Analysis, met with members of the Company's management in
Ann Arbor, Michigan and Boston, Massachusetts to conduct initial due diligence.

     On several occasions between April 30 and May 5, 2003, Mr. Jones and Mr.
Crandall discussed the terms of a non-binding indication of interest. On May 7,
2003, Geac submitted a written non-binding indication of interest to acquire the
Company. The Company and Geac negotiated the final terms of the indication of
interest over the next few days. The final indication of interest provided for
Geac to acquire all of the Company's outstanding Shares for an aggregate price
of $53 million in cash (which represented approximately $4.68 per Share), with
standard conditions, including satisfactory completion of due diligence and
execution of voting and tender agreements by each of Codec and Dennis Ganster.
Geac also indicated that the transaction
                                        24


would be fully financed from Geac's available cash. On May 8, 2003, the Board
met to discuss the status of discussions with the parties that had expressed an
interest in acquiring the Company. On May 12, 2003, Dykema Gossett PLLC, counsel
to the Company, provided Geac with a draft merger agreement. On May 13, 2003,
the non-binding indication of interest was approved by the Company's Board and
executed by the parties. The indication of interest provided Geac with an
exclusivity period through June 3, 2003, during which the Company agreed to not
knowingly solicit, initiate, participate in discussions or negotiations
(including discussions pending on the date of the letter) or otherwise cooperate
in any way with any other person, entity or group concerning an acquisition of
the Company or enter into any agreement to effect any such transaction;
provided, however, that the exclusivity period terminated in the event that Geac
proposed paying total consideration in any acquisition of the Company that was
less than $53 million. In any event, the exclusivity period did not preclude the
Company from complying with the requirements of Securities and Exchange
Commission Rule 14e-2.

     On May 14, 2003, Geac commenced confirmatory due diligence, including
accounting and legal due diligence, of the Company. Between May 20 and May 28,
2003, representatives from PricewaterhouseCoopers LLP, Geac's accountants,
visited the Company's facilities and conducted financial and accounting due
diligence, while Geac's legal representatives from Blake, Cassels & Graydon LLP
and Foley Hoag LLP also conducted legal due diligence. On May 29 and June 4,
2003, representatives from the Company, including Mr. Jarzynski, held telephone
conferences with representatives from Geac regarding due diligence matters. On
June 2, 2003, Mr. Crandall advised Mr. Jones that the exclusivity period
contained in the indication of interest would not be extended. On June 5, 2003,
Mr. Crandall and Mr. Jones had a telephone discussion and exchanged e-mail
correspondence regarding certain due diligence matters.

     On June 6, 2003, the Company received initial comments from Geac to the
draft of the Merger Agreement that had been prepared by the Company's legal
counsel, as well as a draft tender and voting agreement. On the evening of June
6, 2003, Mr. Crandall was contacted by Mr. Jones who indicated that Geac's board
had met that evening to review the results of due diligence review and the
status of the transactions, and had determined to lower its aggregate offer
price to $48 million (which represented approximately $4.27 per share). Mr.
Crandall then indicated to Mr. Jones that he did not believe that the Company's
Board would accept such a proposal. Mr. Crandall and Mr. Jones had subsequent
discussions over the next few days, and on the evening of June 8, 2003, Geac
agreed to increase the aggregate offer price to $52 million.

     The Company's legal counsel provided responses to Geac's comments on the
Merger Agreement on June 10, 2003 and provided comments on the tender and voting
agreement on June 12, 2003. On June 13, 2003, the Board met to discuss the
status of discussions with Geac and the terms of the proposed Merger Agreement.
The parties then engaged in negotiation of the specific terms of the transaction
documents, including, without limitation, the conditions to the Offer, the
circumstances under which the parties could terminate the Merger Agreement and
the amount of the termination fee if the Company terminated the Merger
Agreement. Through the course of negotiations, the Company and its legal and
financial advisors continued to provide Geac and its financial and legal
advisors with material in response to Geac's due diligence requests. On several
occasions during this period of negotiation, Mr. Crandall and Mr. Jones had
telephone conversations to discuss and resolve certain contract terms and other
outstanding issues.

     On June 18, 2003, Geac informed the Company that Geac's board had approved
the Merger Agreement and other related agreements, subject to the resolution of
outstanding issues and the finalization of definitive documentation in form
satisfactory to Messrs. Jones and Birch.

     On June 19, 2003, the Company's Board of Directors held a meeting to
evaluate the proposed transaction with Geac. At that meeting, prior to any Board
action, the Company's legal counsel reviewed the Board's fiduciary duties and
the material terms of the Merger Agreement, including the termination provisions
and break-up fees. Also at such meeting, Bryant Park Capital rendered to the
Board an oral opinion (which opinion was confirmed by delivery of a written
opinion dated June 22, 2003, the date of the Merger Agreement) to the effect
that, as of the date of the opinion and based upon and subject to certain
matters stated in the opinion, the $4.60 net per Share cash consideration to be
received in the Offer and the Merger,

                                        25


taken together, by holders of Shares (other than Geac and its affiliates) was
fair, from a financial point of view, to such holders. After further discussion,
the Board approved the Merger Agreement and other related agreements, and
determined that the transaction was fair to and in the best interests of the
Company's shareholders and declared it advisable.

     After the meeting of the Company's Board of Directors on June 19, 2003, the
Company informed Geac that its Board had approved the transactions with Geac,
subject to resolution of outstanding issues and finalization of definitive
documentation. Over the next several days, legal counsel for each of the Company
and Geac negotiated resolution of all remaining outstanding issues and Geac
completed negotiations and signed employment agreements with Messrs. Hartlen and
King, which was a condition to Geac and Purchaser signing the Merger Agreement.

     The Merger Agreement and other related agreements were executed on June 22,
2003, and the transaction was announced publicly through press releases issued
by each of the Company and Geac before the opening of trading in the Company's
Common Stock on the Nasdaq National Market(R) on June 23, 2003.

     The Company's Board of Directors met on June 29, 2003 to consider a letter
received from a party expressing an interest in submitting a proposal to acquire
all of the outstanding Shares at an unspecified cash price, subject to
completion of due diligence. The letter indicated that the proposal would be
"materially higher" than $4.60 per Share. The Company's Board concluded at the
meeting that, because the letter did not contain sufficient details concerning
the proposal, including the absence of a price and financing information, the
Board was not able to determine that the proposal may result in a Superior
Proposal (as defined in "Item 4. The Solicitation or Recommendation -- Reasons
for the Recommendation" below) and advised the third party of that conclusion.

     On July 1, 2003, in accordance with the Merger Agreement, the Purchaser
commenced the Offer.

11.  PURPOSE OF THE OFFER; PLANS FOR THE COMPANY

     The purpose of the Offer is to enable Geac to acquire control of, and the
entire equity interest in, the Company. The Offer is being made pursuant to the
Merger Agreement and is intended to increase the likelihood that the Merger will
be effected. The purpose of the Merger is to acquire all of the outstanding
Shares not purchased pursuant to the Offer. Pursuant to the terms of the Merger
Agreement, Geac currently intends, promptly after consummation of the Offer, to
exercise its right under the Merger Agreement to designate a majority of
directors to the Company Board to reflect its total voting power of Shares then
outstanding. Geac and Purchaser intend to consummate the Merger as soon as
possible following the consummation of the Offer.

     Except as otherwise provided in this Offer to Purchase, it is expected
that, initially following the Merger, the business and operations of the Company
will be continued substantially as they are currently being conducted. Geac will
continue to evaluate the business and operations of the Company during the
pendency of the Offer and after the consummation of the Offer and the Merger and
will take such actions as it deems appropriate under the circumstances then
existing. In addition, Geac will continue to seek additional information about
the Company during such time periods. Thereafter, Geac intends to review such
additional information as part of a comprehensive review of the Company's
business, operations, capitalization and management with a view to optimizing
development of the Company's potential in conjunction with Geac's businesses.

     Shareholders of the Company who tender and sell their Shares in the Offer
will cease to have any equity interest in the Company and any right to
participate in its earnings and future growth. If the Merger is consummated,
non-tendering shareholders will no longer have an equity interest in the Company
and instead will have only the right to receive cash consideration pursuant to
the Merger Agreement. Similarly, after selling their Shares in the Offer or the
subsequent Merger, shareholders of the Company will not bear the risk of any
decrease in the value of the Company.

     Under Section 711 of the Business Corporation Act of the State of Michigan,
as amended (the "Business Corporation Act"), if a corporation owns at least 90%
of the outstanding shares of each class of voting
                                        26


securities of a subsidiary corporation, the corporation holding such stock may
merge such subsidiary into itself, or itself into such subsidiary pursuant to a
short-form merger, without any action or vote on the part of the board of
directors or the shareholders of such other corporation. In the event that we
acquire in the aggregate, pursuant to the Offer, by exercise of the Top-Up
Option or otherwise, at least 90% of the Shares then outstanding, then, at the
election of the Purchaser, a short-form merger of us with and into the Company
could be effected without any further approval of the Company Board or the
shareholders of the Company. Even if we do not own 90% of the Shares outstanding
following consummation of the Offer, Geac could seek to purchase additional
Shares in the open market or otherwise in order to reach the applicable 90%
threshold and employ such a short-form merger. The per share consideration paid
for any Shares so acquired in open market purchases may be greater or less than
the Offer Price. Geac presently intends to effect a short-form merger, if
permitted to do so under the Business Corporation Act, pursuant to which
Purchaser will be merged with and into the Company.

     Except as described above or elsewhere in this Offer to Purchase, Purchaser
and Geac have no present plans that would relate to or result in an
extraordinary corporate transaction involving the Company or any of their
respective subsidiaries (such as a merger, reorganization, liquidation,
relocation of any operations or sale or other transfer of a material amount of
assets), any sale or transfer of a material amount of assets of the Company or
any of its subsidiaries, any change in the Company Board or management, any
material change in the Company's capitalization or dividend policy or any other
material change in the Company's corporate structure or business.

12.  DESCRIPTION OF MERGER AGREEMENT, VOTING AND TENDER AGREEMENTS AND
     CONFIDENTIALITY AGREEMENTS

     THE FOLLOWING IS A SUMMARY OF MATERIAL PROVISIONS OF THE MERGER AGREEMENT,
VOTING AND TENDER AGREEMENTS AND CONFIDENTIALITY AGREEMENTS. THIS SUMMARY IS NOT
A COMPLETE DESCRIPTION OF THE TERMS AND CONDITIONS OF SUCH AGREEMENTS AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH AGREEMENTS FILED
WITH THE SEC AS EXHIBITS TO THE SCHEDULE TO AND IS INCORPORATED HEREIN BY
REFERENCE. CAPITALIZED TERMS NOT OTHERWISE DEFINED BELOW WILL HAVE THE MEANINGS
SET FORTH IN THE MERGER AGREEMENT. THE MERGER AGREEMENT, VOTING AND TENDER
AGREEMENTS AND CONFIDENTIALITY AGREEMENTS MAY BE EXAMINED, AND COPIES OBTAINED,
AS SET FORTH IN SECTION 8 OF THIS OFFER TO PURCHASE.

  MERGER AGREEMENT

     The Offer.  The Merger Agreement provides for the commencement of the Offer
on or before July 3, 2003. Our obligation to accept for payment, purchase and
pay for Shares validly tendered and not withdrawn pursuant to the Offer is
subject to the satisfaction of each of the conditions of the Offer including the
condition that at least a majority of the Shares outstanding on a fully diluted
basis have been validly tendered and not withdrawn prior to the expiration of
the Offer and certain other conditions described in Section 15 below. We
expressly reserve the right to waive the Minimum Condition or any of the other
conditions to the Offer and to make any change in the terms or conditions of the
Offer. However, without the prior written consent of the Company, we will not
(a) waive the Minimum Condition, (b) change the form of consideration payable in
the Offer, (c) decrease the price per Share or the number of Shares sought in
the Offer, (d) impose conditions to the Offer in addition to those set forth in
the Merger Agreement or are otherwise adverse to the holders of the Shares, or
(e) waive the condition that by the Determination Time (as defined in the Merger
Agreement) any applicable waiting period under the HSR Act or any laws, rules or
regulations analogous to the HSR Act existing in foreign jurisdictions has
expired or been terminated.

     Upon the applicable Expiration Date of the Offer, we may extend the Offer
beyond the initial Expiration Date, without the consent of the Company, in the
following events: (i) from time to time, but in no event to a date later than
October 1, 2003, if, at the initial Expiration Date (or extended Expiration Date
of the Offer, if applicable), one or more of the conditions to the Offer (other
than the Minimum Condition) shall not have been satisfied or waived, until such
conditions are satisfied or waived; (ii) for any period required by any SEC
rule, regulation, interpretation or position applicable to the Offer or any
period required by applicable United States law, or (iii) if all of the
conditions to the Offer are satisfied or waived but the number of Shares validly
tendered and not withdrawn is less than ninety percent (90%) of the outstanding
number of Shares for a
                                        27


subsequent offering period (a "Subsequent Offering Period") consistent with Rule
14d-11 of the Exchange Act; provided that the Expiration Date of the Offer may
not extend beyond 12:00 midnight, Eastern time, on October 1, 2003; and provided
further, that, in the case of any such Subsequent Offering Period, we (x) accept
and pay for Shares validly tendered and not withdrawn, as soon as reasonably
practical prior to the date of such extension, (y) otherwise meet the
requirements of Rule 14d-11 under the Exchange Act in connection with such
Subsequent Offering Period and (z) waive any condition to the consummation of
the Merger other than the requirement that there be no statute, rule or
regulation by any governmental entity or an injunction by a court of competent
jurisdiction which prevents the consummation of the Merger. In addition, we have
agreed that, if requested by the Company, we will (a) extend the Offer if at the
Expiration Date, no conditions to the Offer (other than the conditions relating
to suits, actions or proceedings or applicable statutes, rules, regulations or
injunctions) then excuse performance by us, for up to 20 business days after
such previously scheduled Expiration Date, or (b) provide a Subsequent Offering
Period if there are validly tendered Shares then owned by Geac representing at
least eighty percent (80%), but not more than ninety percent (90%), of the
Shares outstanding. Upon the satisfaction or waiver of all the conditions to the
Offer and subject to the terms of the Merger Agreement, we will accept for
payment, purchase and pay for, in accordance with the terms of the Offer, all
Shares validly tendered and not withdrawn pursuant to the Offer as soon as
reasonably practicable after the expiration of the Offer.

     In order to provide a Subsequent Offering Period, we must satisfy the
following conditions:

     - the Offer was open for a minimum of 20 business days and has expired;

     - we accept and promptly pay for all Shares tendered during the initial
       Offer period;

     - we announce the results of the Offer, including the approximate number
       and percentage of Shares tendered, no later than 9:00 a.m., Eastern time,
       on the next business day after the Expiration Date and immediately begin
       the Subsequent Offering Period;

     - we immediately accept and promptly pay for Shares as they are tendered
       during the Subsequent Offering Period; and

     - we pay the same form and amount of consideration for all Shares tendered
       during the Subsequent Offering Period.

     A Subsequent Offering Period, if one is provided, is not an extension of
the Offer. A Subsequent Offering Period would be an additional period of time,
following the expiration of the Offer, in which shareholders may tender Shares
not tendered during the Offer.

     Pursuant to Rule 14d-7 promulgated under the Exchange Act, no withdrawal
rights will apply to Shares tendered in a Subsequent Offering Period and no
withdrawal rights apply during the Subsequent Offering Period with respect to
Shares tendered in the Offer and accepted for payment. The same consideration,
the Offer Price or any higher price per Share paid in the Offer, will be paid to
shareholders tendering Shares in the Offer or in a Subsequent Offering Period,
if one is provided.

     Recommendation.  The Company has represented to Purchaser in the Merger
Agreement that the Company Board has (a) unanimously determined that the Merger
Agreement and the transactions contemplated thereby, including, without
limitation, the Offer, the Merger and the purchase of the Shares and associated
Rights contemplated by the Offer (collectively, the "Transactions") are fair to
and in the best interests of the Company's shareholders, (b) unanimously
approved and adopted the Merger Agreement and the Transactions, including the
Offer and the Merger, in accordance with the requirements of Michigan Law and
(c) resolved to recommend acceptance of the Offer and approval and adoption of
the Merger Agreement and the Merger by its shareholders. However, such
recommendation may be withdrawn in the event that the Company receives an
Acquisition Proposal (as defined below) which the Company Board determines in
good faith after consultation with and advice from the Company Financial Advisor
(as defined in the Merger Agreement) or other financial advisor of nationally
recognized reputation constitutes a Superior Proposal and the Company Board
determines in good faith, after consultation with and advice from outside legal
counsel, that the failure to take such action would not be consistent with its
fiduciary duties under applicable law. The

                                        28


Company further represented that the Company Financial Advisor has delivered to
the Company Board its opinion to the effect that, as of the date of the Merger
Agreement, the consideration to be paid in the Offer and the Merger is fair,
from a financial point of view, to the holders of Shares.

     The Merger.  The Merger Agreement provides that, at the Effective Time,
Purchaser will be merged with and into the Company. Following the Merger, the
Company will continue as the surviving corporation (the "Surviving Corporation")
and will be an indirect, wholly owned subsidiary of Geac. The Company has agreed
that if approval of the Company's shareholders is required under Michigan law to
consummate the Merger, the Company will cause a meeting of its shareholders (the
"Company Shareholder Meeting") to be duly called and held as soon as practicable
following the consummation of the Offer, for the purpose of voting on the
approval and adoption of the Merger Agreement and the Merger. The Company has
also agreed to, among other things, prepare and file proxy materials with the
SEC in connection with the Company Shareholder Meeting.

     Certificate of Incorporation and Bylaws.  The Merger Agreement provides
that the articles of incorporation of the Company in effect at the Effective
Time shall be the articles of incorporation of the Surviving Corporation until
amended in accordance with applicable law.

     Directors and Officers.  Pursuant to the Merger Agreement, and subject to
applicable law, from and after the Effective Time, until successors are duly
elected or appointed and qualified in accordance with applicable law, (i) the
directors of Purchaser at the Effective Time shall be the directors of the
Surviving Corporation and (ii) the officers of the Company at the Effective Time
shall be the officers of the Surviving Corporation.

     Conversion of Securities.  Pursuant to the Merger Agreement, at the
Effective Time (x) each Share outstanding immediately prior to the Effective
Time (other than Shares held by Geac, Purchaser or any of Geac's direct or
indirect wholly owned subsidiaries), together with the Rights attached thereto,
shall be converted into the right to receive the Offer Price; (y) each Share
that is owned by Geac, Purchaser or any of their respective subsidiaries
immediately prior to the Effective Time will be canceled and no payment shall be
made with respect to such Shares; and (z) each Share of common stock of
Purchaser outstanding immediately prior to the Effective Time will be converted
into and become one share of common stock of the Surviving Corporation with the
same rights, powers and privileges as the shares so converted and shall
constitute the only outstanding shares of capital stock of the Surviving
Corporation.

     Stock Options.  The Merger Agreement provides that at or immediately prior
to the Effective Time each outstanding Stock Option, whether or not vested or
exercisable and without regard to any agreements qualifying the right to retain
or exercise any such option or award, will be canceled, and the Surviving
Corporation will pay each holder of any such option at or promptly after the
Effective Time for each such option an amount in cash determined by multiplying
(a) the excess, if any, of the Merger Consideration per Share over the
applicable exercise price or base price, if any, of such option by (b) the
number of Shares underlying such option.

     Top-Up Option.  Pursuant to the Merger Agreement, the Company granted to
Purchaser the Top-Up Option to purchase up to that number of Shares (the "Top-Up
Option Shares") equal to the lowest number of Shares that, when added to the
number of Shares owned by Purchaser at the time of such exercise, will
constitute one share more than 90% of the Shares then outstanding on a fully
diluted basis (assuming the issuance of the Top-Up Option Shares and the
exercise of all outstanding exercisable options to purchase Shares with an
exercise price less than the Offer Price) at a purchase price per Top-Up Option
Share equal to the Offer Price.

     Purchaser may, at its election, exercise the Top-Up Option, in whole but
not in part, at any one time after the occurrence of a Top-Up Exercise Event and
prior to the Top-Up Termination Date (as defined below). A "Top-Up Exercise
Event" will occur upon Purchaser's acceptance for payment pursuant to the Offer
of Shares constituting at least 80% of the Shares then outstanding. The "Top-Up
Termination Date" will occur upon the earliest to occur of (i) the Effective
Time, (ii) the termination of the Merger Agreement, (iii) the date that is ten
business days after the occurrence of a Top-Up Exercise Event, unless the
Purchaser has notified the Company of its intent to exercise the Top-Up Option
in accordance with the terms and conditions of the

                                        29


Merger Agreement and (iv) the date that is ten business days after the Top-Up
Response Date (as defined below) unless the Top-Up Closing (as defined below)
has previously occurred.

     The Company's obligation to deliver Top-Up Option Shares upon the exercise
of the Top-Up Option is subject to the following conditions: (i) that any
applicable waiting period under the HSR Act and regulations analogous to the HSR
Act existing in foreign jurisdictions relating to the issuance of the Top-Up
Option Shares will have expired or been terminated; (ii) that no provision of
any applicable law or regulation and no judgment, injunction, or decree
prohibits the exercise of the Top-Up Option or the delivery of the Top-Up Option
Shares in respect of any such exercise; and (iii) delivery of the Top-Up Option
Shares would not require the approval of the Company's shareholders pursuant to
the rules and regulations of the Nasdaq Stock Market.

     Representations and Warranties.  Pursuant to the Merger Agreement, the
Company has made customary representations and warranties to Geac and Purchaser
with respect to, among other matters, its corporate existence and power,
corporate authorization, government authorization, non-contravention,
capitalization, required filings with the SEC, financial statements, disclosure
documents, absence of certain events, absence of undisclosed material
liabilities, compliance with laws and court orders, litigation, finders' fees,
taxes, employee benefit plans, foreign employee benefit plans, antitakeover
statutes and rights agreement, intellectual property, title and conditions of

requirements. Geac has made customary representations and warranties to the
Company with respect to, among other matters, its corporate existence and power,
corporate authorization, government authorization, non-contravention, disclosure
documents, finders' fees and financing.

     Covenants.  The Merger Agreement obligates the Company and its
subsidiaries, from the date of the Merger Agreement and continuing until the
Effective Time, to: (a) conduct their business in the ordinary course consistent
with past practice and (b) use all commercially reasonable efforts to preserve
intact their business organizations and relationships with third parties and to
keep available the services of their officers and employees.

     The Merger Agreement also contains customary covenants restricting certain
activities of the Company during the period from the date of the Merger
Agreement and continuing until the Effective Time. These covenants provide that
the Company will not (and will not permit any of its subsidiaries to) take
certain actions without the prior written consent of Geac, with respect to,
among other things, making or declaring dividends, initiating stock splits,
repurchasing, redeeming or issuing shares of capital stock (other than pursuant
to the exercise of stock options), amending its articles of incorporation or
bylaws, acquiring other significant businesses, selling or licensing its assets
(other than in the ordinary course of business), making significant capital
expenditures, incurring debt, making loans, making a new employee compensation
plan or amending its existing plan, increasing compensation to directors,
officers and employees or entering into new employment arrangements (other than
in the ordinary course of business), paying undisclosed bonuses, changing its
accounting policies, procedures or practices, making a tax election, settling
material income tax liabilities, settling certain litigation, canceling material
insurance policies, entering into material contracts (other than in the ordinary
course of business), agreeing to limit its line of business or geographic area,
liquidating, dissolving or reorganizing its business, altering the corporate
structure of itself or any of its subsidiaries, making payments exceeding
$200,000 (other than in the ordinary course of business), renewing or
terminating significant distribution agreements, agreeing to do any of the
foregoing or redeeming the Rights or terminating the Rights Agreement.

     No Solicitation.  The Merger Agreement provides that the Company will not,
and will not permit any of its subsidiaries to, and will use its best efforts to
ensure that its officers, directors, employees, investment bankers, consultants
or other advisors or agents retained by it or any of its subsidiaries, do not
solicit, initiate or intentionally encourage the submission of any Acquisition
Proposal (as defined below) or engage in discussions or negotiations or furnish
to any person any information with respect to an Acquisition Proposal or
knowingly facilitate any effort or attempt to make an Acquisition Proposal.
Nothing contained in the Merger Agreement prevents the Company Board from
complying with Rule 14d-9 or Rule 14e-2 under the Exchange Act with respect to
any Acquisition Proposal or making any disclosure to the Company's shareholders
if, in the

                                        30


good faith judgment of the Company Board, after consultation with and advice
from outside legal counsel, failure to make such disclosure would constitute a
breach of the fiduciary duties of the Company Board under applicable law or
otherwise violate applicable law.

     The Company may, however, negotiate or otherwise engage in discussions
with, and furnish nonpublic information to, any Person in response to an
unsolicited Acquisition Proposal by such Person if (i) the Company Board
determines in good faith, after consultation with and advice from the Company
Financial Advisor or a financial advisor of nationally recognized reputation,
that such Acquisition Proposal may result in a Superior Proposal (as defined
below) and (ii) such Person executes a confidentiality agreement no less
favorable to the Company than the Confidentiality Agreement (including the
standstill provisions).

     Prior to providing any information to or entering into discussions or
negotiations with any Person in connection with an Acquisition Proposal, the
Company will promptly (i) notify Geac of any Acquisition Proposal, including
providing a copy of any written Acquisition Proposal or amendments or
supplements to such Acquisition Proposal, (ii) inform Geac of the status of any
discussions or negotiations with such a third party and any material changes to
the terms and conditions of such Acquisition Proposal and (iii) deliver to Geac
a copy of any information delivered to such person which has not previously been
delivered by the Company to Geac.

     Except as permitted above, neither the Company Board nor any committee
thereof may, (i) withdraw or modify, or publicly propose to withdraw or modify,
in a manner adverse to Geac, its recommendation discussed above, or take any
action not explicitly permitted by the Merger Agreement that would be
inconsistent with, its approval of the Offer and the Merger, (ii) approve or
recommend, or publicly propose to approve or recommend, any Acquisition Proposal
or (iii) cause the Company to enter into any letter of intent, agreement in
principle, acquisition agreement, commitment or similar agreement related to any
Acquisition Proposal. Notwithstanding the foregoing, the Company Board will be
permitted (i) not to recommend to its shareholders acceptance of the Offer
and/or approval and adoption of the Merger Agreement and the Merger, (ii) to
withdraw, or modify in a manner adverse to Geac, its recommendation to its
shareholders discussed above, (iii) to approve or recommend any Superior
Proposal or (iv) to terminate the Merger Agreement in accordance with its terms
and in connection therewith enter into an agreement with respect to such
Superior Proposal, but only if (y) the Company has received an Acquisition
Proposal which the Company Board determines in good faith after consultation
with and advice from the Company Financial Advisor or other financial advisor of
nationally recognized reputation constitutes a Superior Proposal and (z) the
Company Board determines in good faith, after consultation with and advice from
outside legal counsel, that the failure to take such action would not be
consistent with its fiduciary duties under applicable law.

     Under the Merger Agreement, "Acquisition Proposal" means any offer or
proposal for, or any inquiry or indication of interest in, (i) any sale, lease,
exchange, mortgage, transfer or other disposition of 50% or more of the
consolidated assets of the Company and its Subsidiaries, (ii) any acquisition or
purchase of an equity interest in the Company representing in excess of 15% of
the power to vote for the election of the directors of the Company, or any
tender offer or exchange offer for equity securities of the Company as a result
of which the offeror would hold such an equity interest in the Company, (iii)
any merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company, or any of its
Subsidiaries whose assets, individually or in the aggregate, constitute more
than 50% of the consolidated assets of the Company, (iv) a plan of liquidation
or extraordinary dividend relating to more than 50% of its total assets or (v)
the repurchase by the Company or its Subsidiary of more than 50% of the
outstanding Shares, in each case other than the Transactions.

     Under the Merger Agreement, "Superior Proposal" means any bona fide written
Acquisition Proposal, not solicited by the Company or by any affiliate or agent
of the Company, which contains no financing contingency, or for which financing
is reasonably determined to be available by the Company Board, and which the
Company Board determines in good faith, after consultation with and advice from
the Company Financial Advisor or other financial advisor of nationally
recognized reputation, and taking into account all the terms and conditions of
the Acquisition Proposal is more favorable to the Company's shareholders (in
their capacities as stockholders) from a financial point of view than the Offer
and Merger.

                                        31


     Other Actions.  The Merger Agreement provides that the Company, Geac, and
Purchaser, will:

     - use all commercially reasonable efforts to take, or cause to be taken,
       all actions and to do, or cause to be done, all things necessary, proper
       or advisable under applicable laws and regulations to consummate the
       Transactions, including but not limited to making all filings with the
       SEC necessary to consummate such transactions,

     - each file a Notification and Report Form pursuant to the HSR Act with
       respect to the Transactions as promptly as practicable and in any event
       within ten business days of the date of the Merger Agreement and to
       supply as promptly as practicable any additional information and
       documentary material that may be requested pursuant to the HSR Act and to
       take all other actions necessary to cause the expiration or termination
       of the applicable waiting periods under the HSR Act as soon as
       practicable, and

     - use all commercially reasonable efforts to (i) cooperate in all respects
       with each other in connection with any filing or submission and in
       connection with any investigation or other inquiry, including any
       proceeding initiated by a private party, (ii) keep the other party
       informed in all material respects of any material communication received
       by such party from, or given by such party to, the Federal Trade
       Commission (the "FTC"), the Antitrust Division of the Department of
       Justice (the "Antitrust Division") or any other governmental authority
       and of any material communication received or given in connection with
       any proceeding by a private party, in each case regarding any of the
       Transactions and (iii) permit the other party to review any material
       communication given by it to, and consult with each other in advance of
       any meeting or conference with, the FTC, the Antitrust Division or any
       such other governmental authority or, in connection with any proceeding
       by a private party, with any other Person.

     Company Shareholder Meeting.  Pursuant to the Merger Agreement, if required
by Michigan law in order to consummate the Merger, the Company, acting through
the Company Board, will call and hold a meeting of its shareholders as soon as
reasonably practicable after consummation of the Offer for the purpose of voting
on the approval and adoption of the Merger Agreement and the Merger (the
"Company Shareholder Meeting"). If Purchaser acquires at least 90% of the
outstanding Shares, however, the parties will take all necessary and appropriate
action to cause the Merger to become effective, in accordance with Section 711
of the Business Corporations Act, without a meeting of the shareholders of the
Company.

     Company Board Representation.  The Merger Agreement provides that upon
acceptance for payment by Purchaser of a number of Shares pursuant to the Offer
that satisfies the Minimum Condition, Geac is entitled to designate the number
of directors, rounded up to the next whole number, on the Company Board as is
equal to the product of (i) the total number of directors on the Company Board
(giving effect to any increase in the number of directors pursuant to this
provision) and (ii) the percentage that the number of Shares beneficially owned
by Geac (including Shares accepted for payment) bears to the total number of
Shares outstanding, and the Company will take all action necessary to cause
Geac's designees to be elected or appointed to the Company Board, including,
without limitation, increasing the number of directors and seeking and accepting
the resignations of incumbent directors. At such time, the Company will also use
its best efforts to cause individuals designated by Geac to constitute the
number of members, rounded up to the next whole number, on each committee of the
Company Board other than any such committee of independent directors established
to take action under the Merger Agreement, as more fully described below, that
represents the same percentage as such individuals represent on the Company
Board. However, if Geac's designees are appointed or elected to the Company
Board, the Company Board will at all times until the Effective Time have at
least two directors who are directors on the date of the Merger Agreement or who
are neither officers or employees of the Company or Geac or any of their
respective affiliates (the "Independent Directors"); provided that if less than
two Independent Directors remain, the other directors will designate persons to
fill such vacancies who meet the foregoing criteria and such persons will be
deemed to be Independent Directors for all purposes of this Agreement.

     Following the election or appointment of Geac's designees and until the
Effective Time, the approval of the majority of Independent Directors will be
required to authorize (and such authorization will constitute the authorization
of the Company Board and no other action on the part of the Company, including
any action by

                                        32


any other directors of the Company, will be required to authorize) any
termination or amendment of the Merger Agreement by the Company (other than in
relation to the Company's obligation to deliver the Top-Up Option Shares), any
extension of time for performance of any obligation or action under the Merger
Agreement by Geac or Purchaser, any waiver of compliance with any of the
agreements or conditions contained in the Merger Agreement for the benefit of
the Company (other than in relation to the Company's obligation to deliver the
Top-Up Option Shares), any action as to which the consent or agreement of the
Company is required under the Merger Agreement, and the assertion or enforcement
of the Company's rights under this Agreement to object to (i) failure to
consummate the Merger for failure of a condition contained herein for the
benefit of the Company to be satisfied or (ii) a termination of the Merger
Agreement Agreement.

     Access to Information.  The Merger Agreement provides that, during the
period after the execution of the Merger Agreement and prior to the Effective
Time, and subject to applicable law and the Company Confidentiality Agreement,
the Company will:

     - give Geac, its counsel, financial advisors, auditors and other authorized
       representatives reasonable access to the offices, properties, books and
       records of the Company and its subsidiaries,

     - furnish to Geac, its counsel, financial advisors, auditors and other
       authorized representatives such financial and operating data and other
       information as they may reasonably request, and

     - instruct the employees, counsel, financial advisors, auditors and other
       authorized representatives of the Company and its subsidiaries to
       cooperate with Geac in its investigation of the Company and its
       subsidiaries, other than information or documentation relating to
       Acquisition Proposals made by Third Parties.

     Indemnification and Insurance.  Pursuant to the Merger Agreement, Geac and
the Surviving Corporation will, jointly and severally, to the fullest extent
permitted by the Business Corporations Act, for a period of six years following
the Effective Time, indemnify and hold harmless each present and former officer
and director of the Company and of any Subsidiary of the Company (each an
"Indemnified Person") in respect of acts or omissions occurring at or prior to
the Effective Time to the fullest extent permitted by Michigan Law or provided
under the Company's articles of incorporation and bylaws in effect on the date
of the Merger Agreement; provided that such indemnification shall be subject to
any limitation imposed from time to time under applicable law. The Surviving
Corporation and Geac will pay all expenses, including reasonable fees and
expenses of counsel, that an Indemnified Person may incur in enforcing the
indemnity and related obligations provided for in the Merger Agreement. The
Indemnified Person is entitled to control the defense of any action, suit,
investigation or proceeding with counsel of his or her own choosing reasonably
acceptable to the Surviving Corporation and the Surviving Corporation will
cooperate in the defense thereof, provided that the Surviving Corporation will
not be liable for the fees of more than one counsel for all Indemnified Persons,
other than local counsel, in any one jurisdiction, unless a conflict of interest
shall be caused thereby, and provided further that the Surviving Corporation
will not be liable for any settlement effected without its written consent
(which consent shall not be unreasonably withheld).

     At the date on which Purchaser accepts for payment pursuant to the Offer a
number of Shares that satisfies the Minimum Condition (the "Cut-Off Date"), Geac
shall arrange for the Company to obtain, and following the Effective Date the
Surviving Corporation shall maintain in effect, a fully paid officers' and
directors' liability insurance policy in respect of acts or omissions occurring
prior to the Cut-Off Date covering each such Indemnified Person currently
covered by the Company's officers' and directors' liability insurance policy on
terms with respect to coverage and amount that are no less favorable than those
of such policy in effect on the date hereof and extending for a period of six
years from the Cut-Off Date. The Company Board shall promptly determine in good
faith and shall confirm in writing to Geac whether the officers' and directors'
liability insurance provided, or proposed to be provided, by the Surviving
Corporation is accepted to constitute insurance that is no less favorable as
aforesaid, provided that any time after the Cut-Off Date, any determination to
such effect must include the approval of a majority of the Independent
Directors, and if so approved, shall be binding on Geac, the Surviving
Corporation and all Indemnified Persons. On or after the Cut-Off Date, Geac
shall provide or cause the Company to provide the Independent Directors the same
                                        33


coverage under an officers' and directors' liability insurance policy in respect
of acts or omissions occurring on or after the Cut-Off Date as are provided to
members of the Board of Directors designated by Parent under the Merger
Agreement.

     The indemnification and insurance provisions will survive the consummation
of the Merger at the Effective Time, and will be binding on all successors and
assigns of Geac and the Surviving Corporation. Proper provisions must be made in
the case of transfers of all or substantially all of the assets of Geac, the
Surviving Corporation or their successors and assigns, so that these
indemnification and insurance obligations are assumed by such successors and
assigns. The indemnification rights of each Indemnified Person under the Merger
Agreement shall be in addition to any rights such Person may have under the
articles of incorporation or bylaws of the Company or any of its Subsidiaries,
or under Michigan Law or any other applicable laws.

     Public Announcements.  The Merger Agreement provides that Geac and the
Company will consult with each other before issuing any press release or making
any public statement with respect to the Merger Agreement or the Transactions
and, except as may be required by applicable law or any listing agreement with
The Nasdaq Stock Market, Inc. or any national securities exchange, will not
issue any such press release or make any such public statement prior to such
consultation.

     Certain Employee Benefits.  The Merger Agreement provides that for at least
one year after the Effective Time, Geac shall cause the Surviving Corporation to
provide those of its and its subsidiaries' employees who were employed by the
Company or its subsidiaries immediately prior to the completion of the Offer
(the "Company Employees") with compensation at least as favorable, in the
aggregate, as the compensation provided by the Company and its subsidiaries to
such employees immediately prior to the date of the Merger Agreement, and
benefits that are substantially equivalent in the aggregate to those that are
provided to employees of Geac having comparable levels of responsibility. The
preceding sentence shall not preclude Geac or the Surviving Corporation or its
subsidiaries at any time following the Effective Time from terminating the
employment of any Company employee nor from terminating or amending any employee
plan in accordance with its terms and applicable law and such benefits.

     The Merger Agreement provides further that each Company Employee be given
full credit in respect of his or her employment with the Company and its
subsidiaries for purposes of eligibility, vesting, level of benefits and
service, other than benefit accrual under any defined benefit plans, under any
new employee benefit plans offered by the Surviving Corporation after the Merger
or any benefit plan maintained by Geac in which the Company employee is
permitted to participate (to the extent that the corresponding Benefit Plan
currently provided to Company employees gave such credit).

     Following the Effective Time, Geac will, or will cause the Surviving
Corporation to, (i) cause any pre-existing conditions or limitations and
eligibility waiting periods under any group health plans of Geac or the
Surviving Corporation, in which Company employees are permitted to participate,
to be waived with respect to the Company employees and their eligible dependents
(ii) give each Company employee credit for the plan year in which the Effective
Time occurs toward applicable deductibles and annual out-of-pocket limits for
expenses incurred prior to the Effective Time and (iii) honor, without
modification, perform all acts and pay all amounts required or due under or with
respect to each Benefit Plan and each agreement which relates to any current or
former employee of the Company and its Subsidiaries or the terms of any such
employee's employment or termination of employment, except for any modification
to any such Benefit Plan or agreement to the extent permitted in accordance with
the Merger Agreement.

     Conditions to Consummation of the Merger.  Pursuant to the Merger
Agreement, the respective obligations of Geac, Purchaser and the Company to
complete the Merger are subject to the satisfaction of the following conditions
(collectively, the "Merger Conditions"):

     - if required by Michigan Law, the Merger Agreement must have been approved
       and adopted by the shareholders of the Company in accordance with the
       Business Corporations Act;

     - any applicable waiting period under the HSR Act or comparable period
       under the antitrust laws of other applicable jurisdictions relating to
       the Merger must have expired or been terminated;

                                        34


     - no provision of any applicable law or regulation and no judgment,
       injunction, order or decree must prohibit the consummation of the Merger
       upon the terms contemplated hereby; and

     - Purchaser must have purchased Shares pursuant to the Offer.

     Termination.  Pursuant to its terms, the Merger Agreement may be
terminated, and the Merger may be abandoned, at any time prior to the Effective
Time, whether before or after approval of the Merger by the shareholders of the
Company:

          (i) by mutual written consent of Geac and the Company;

          (ii) by either the Company or Geac:

        - if any court or governmental entity has restrained, enjoined,
          prohibited or otherwise made illegal the Merger by an order (other
          than a temporary restraining order), decree, ruling or other action
          (which order, decree, ruling or other action the parties to the Merger
          Agreement shall use their commercially reasonable efforts to lift);

        - if (x) the Offer shall have expired without any Shares being purchased
          therein or (y) Geac or Purchaser shall not have accepted for payment,
          and paid for, all Shares tendered pursuant to the Offer by October 1,
          2003 (this right to terminate will not be available to any party whose
          breach of this Agreement has been the cause of, or resulted in, the
          failure of Geac or Purchaser to purchase the Shares pursuant to the
          Offer); or

        - if any Person, other than Geac, Purchaser or their affiliates,
          consummates a tender offer or other transaction pursuant to which such
          Person becomes the beneficial owner of more than fifty (50%) percent
          of the then outstanding Shares.

          (iii) by the Company:

        - if Geac or Purchaser fails to commence the Offer pursuant to the
          Merger Agreement (this right to terminate will not be available if the
          Company is at such time in breach of its obligations under the Merger
          Agreement so as to (A) cause a Material Adverse Effect on the Company
          or (B) prevent or materially hinder or delay the purchase of the
          Shares pursuant to the Offer or the Merger;

        - in connection with its entering into a definitive agreement with
          respect to a Superior Proposal, pursuant to the terms of the Merger
          Agreement, if (x) the Company provides written notice to Geac and
          Purchaser of the material terms and conditions of an Acquisition
          Proposal which the Company Board has determined in good faith, after
          consultation with and advice from the Company Financial Advisor or
          other nationally recognized financial advisor and its outside legal
          counsel, constitutes a Superior Proposal, (y) after the third business
          day immediately following delivery of such written notice, the Company
          Board reasonably determines, based upon the advice of the Company
          Financial Advisor or other nationally recognized financial advisor,
          that any proposal made by Geac and Purchaser supplementing the terms
          and conditions of the Offer, is not at least as favorable to the
          Company and the Company's shareholders as the terms and conditions of
          such Acquisition Proposal specified in the preceding bullet; or

        - if (x) Geac or Purchaser shall have breached or failed to perform in
          all material respects any of their obligations under the Merger
          Agreement, or any of the representations and warranties of Geac or
          Purchaser contained in the Merger Agreement shall not be true in all
          material respects as of the date of the Merger Agreement or at any
          time prior to the Effective Date as if made at and as of such time
          (except as to any representation or warranty which speaks as of a
          specific date, which must be untrue as of such date) and (y) such
          breach or failure to perform obligations, or failure of the
          representations and warranties to be true, cannot be or has not been
          cured, in all material respects, within 15 days after the giving of
          written notice to Geac and Purchaser.

                                        35


          (iv) by Geac:

        - if, due to an occurrence, not resulting from a breach by Geac or
          Purchaser of their obligations hereunder, which makes it impossible to
          satisfy any of the Offer Conditions (as defined in Section 15), Geac
          or Purchaser shall have failed to commence the Offer on or prior to
          July 3, 2003;

        - if, prior to the consummation of the Offer, the Company shall have
          breached any representation, warranty, covenant or other agreement
          contained in the Merger Agreement which (y) gives rise to the failure
          of a condition set forth in paragraph (c) or (d) of the Offer
          Conditions described in Section 15 and (z) cannot be or has not been
          cured, in all material respects, within the later of 15 days after the
          giving of written notice to the Company or the initial expiration of
          the Offer (or such later date upon which the Offer shall expire in
          accordance with the Merger Agreement);

        - if, whether or not permitted to do so, the Company Board withdraws or
          modifies in a manner adverse to Geac or Purchaser (or fails, at the
          request of Geac, to reaffirm within 5 business days after the
          request), its approval or recommendation of the Offer, the Merger or
          the Agreement, or approves or recommends any Acquisition Proposal; or

        - if, whether or not permitted to do so, the Company enters into a
          written acquisition agreement agreeing to an Acquisition Proposal,
          including a Superior Proposal otherwise entered into in accordance
          with the terms of the Merger Agreement.

     As used in the Merger Agreement, "Material Adverse Effect" means, with
respect to any Person, any change, result, effect, event, occurrence or state of
facts (or any development that has had or is reasonably likely to have any
change or effect) that is or would reasonably be expected to be materially
adverse to the business, financial condition, assets, liabilities or results of
operations or prospects of such Person and its Subsidiaries, taken as a whole,
or which is or would reasonably be expected to be materially adverse to the
ability of such Person to consummate the Transactions; provided, however, that
none of the following will be deemed in itself, either alone or in combination
to constitute, and none of the following will be taken into account in
determining whether there has been, a Material Adverse Effect: (i) any such
effect resulting from or arising in connection with this Agreement or the
Transactions or the execution or announcement hereof, (ii) changes in
circumstances or conditions affecting the industry in which the Company and its
Subsidiaries operate or affecting software companies in general, (iii) changes
in general economic, regulatory or political conditions or in financial or
securities markets in the United States or elsewhere, (iv) changes in generally
accepted accounting principles or (v) any change in the price at which the
Shares are publicly traded. The failure of a Person to meet any particular
revenue or earnings forecast or estimate for any period ending after the date of
the Merger Agreement, including estimates prepared by equity analysts or other
third parties, as well as internal forecasts prepared by management of such
Person, shall not, in and of itself, be deemed to constitute a Material Adverse
Effect..

     Fees and Expenses.  Except as provided in the Merger Agreement, whether or
not the Offer or the Merger is consummated, all costs and expenses incurred in
connection with the Merger Agreement and the Transactions will be paid by the
party incurring those expenses. The Merger Agreement further provides that in
the event that (1) the Merger Agreement is terminated by Geac pursuant to the
fourth bullet point in paragraph (iv) described above under "Termination," (2)
the Merger Agreement is terminated by the Company pursuant to the second bullet
point under paragraph (iii) described above under "Termination," or (3) the
Merger Agreement is terminated by the Company or Geac pursuant to the third
bullet point under paragraph (ii) described above under "Termination," then the
Company will pay Geac a termination fee of $1,850,000 plus an amount equal to
Geac's actual and reasonably documented out of pocket expenses up to an
aggregate of $750,000 in connection with the Offer, the Merger, the Merger
Agreement and the consummation of the Transactions.

     In the Merger Agreement, the Company acknowledged that the agreements
contained under "Fees and Expenses" are an integral part of the Transactions,
and that, without these agreements, Geac would not have entered into the Merger
Agreement; accordingly if the Company fails to promptly pay the amounts due as

                                        36


described above, and Geac commences a suit which results in the payment of such
fees, then the Company will also pay to Geac its costs and expenses in
connection with such amounts plus interest. However, if Geac commences such a
suit but does not substantially prevail in such suit, then Geac will pay to the
Company the Company's costs and expenses in connection with such amounts plus
interest.

     Amendments and Waivers.  The Merger Agreement provides that any provision
of the Merger Agreement may be amended or waived prior to the Effective Time if,
but only if, such amendment or waiver is in writing and is signed, in the case
of an amendment, by each party to the Merger Agreement or, in the case of a
waiver, by each party against whom the waiver is to be effective, provided that,
after the adoption of the Merger Agreement by the shareholders of the Company
and without their further approval, no such amendment or waiver shall reduce the
amount or change the kind of consideration to be received in exchange for the
Shares. No failure or delay by any party in exercising any right, power or
privilege under the Merger Agreement will operate as a waiver thereof nor will
any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege.

  VOTING AND TENDER AGREEMENTS

     Geac and Purchaser have entered into a Voting and Tender Agreement with
Dennis G. Ganster and with Codec Systems Limited and Anthony Stafford (the
"Voting Agreement Signatories"). Pursuant to the Voting and Tender Agreements,
each Voting Agreement Signatory has agreed to tender his or its Shares in the
Offer not later than one business day prior to the Expiration Date and not to
withdraw such Shares once tendered. Each Voting Agreement Signatory has also
agreed to vote his or its Shares (a) in favor of the Merger, the Merger
Agreement and the Transactions, (b) against any action or agreement that would
result in a breach in any material respect of any covenant, representation or
warranty or any other obligation of the Company under the Merger Agreement, and
(c) against any action or agreement that would materially impede, interfere with
or attempt to discourage the Offer or the Merger. In addition, under the Voting
and Tender Agreements (so long as they remain in effect), each Voting Agreement
Signatory has granted an irrevocable proxy to and appointed Geac as such Voting
Agreement Signatory's proxy and attorney-in-fact to vote, act by written consent
or grant a consent, proxy or approval in respect of all Shares held by the
Voting Agreement Signatory with respect to such vote or action by written
consent, solely for the purposes of voting in favor of the Merger, the Merger
Agreement (as amended from time to time, except for an amendment that would
result in termination of the Voting and Tender Agreement pursuant to the terms
thereof) and any of the transactions contemplated by the Merger Agreement.

     The agreements contained in each Voting and Tender Agreement shall
terminate automatically upon the earliest to occur of (a) an amendment or
modification to or waiver under the Merger Agreement, including the terms and
conditions of the Offer, that would be economically adverse to the Voting
Agreement Signatory, (b) the termination of the Merger Agreement, (c) the
completion of the Merger, or (d) December 31, 2003.

  CONFIDENTIALITY AGREEMENTS

     Pursuant to the Company Confidentiality Agreement, Geac has agreed, among
other things, to keep confidential certain information concerning the Company
furnished to it and its representatives by or on behalf of the Company or its
representatives ("Company Information"), and to use the Company Information
solely for the purpose of evaluating a possible transaction with the Company.
Geac has further agreed to maintain the confidentiality of any discussions or
negotiations with the Company and, upon request, to redeliver or destroy all
Company Information. Geac also agreed that, except pursuant to a transaction
approved by the board of directors of the Company, it will not, directly or
indirectly, effect or seek, offer or propose to effect certain transactions
involving the Company, including any acquisition of securities or assets of the
Company or any of its subsidiaries or any tender or exchange offer, merger or
other business combination involving the Company or any of its subsidiaries for
a period of twelve months from the date of the Company Confidentiality
Agreement. For a period of one year after the date of the Company
Confidentiality Agreement, Geac will not, without the Company's prior written
consent, employ or solicit to employ certain of the current officers or
employees of the Company, provided that after six months from the date of the
Company Confidentiality Agreement Geac may employ any such person who responds
to a general solicitation for employment.
                                        37


     Pursuant to the Geac Confidentiality Agreement, the Company has agreed,
among other things, to keep confidential certain information concerning Geac
furnished to it and its representatives by or on behalf of Geac or its
representatives ("Geac Information"), and to use the Geac Information solely for
the purpose of understanding timing considerations relating to the Transactions.
The Company has further agreed to maintain the confidentiality of any
discussions or negotiations with Geac and, upon request, to redeliver or destroy
all Information. The Company acknowledges that the Geac Information includes
material non-public information and that it and its directors, officers,
employees, representatives and advisors are aware of the restrictions imposed by
applicable securities laws on a person possession material non-public
information about a public company.

  RULE 13E-3

     The SEC has adopted Rule 13e-3 under the Exchange Act, which is applicable
to certain "going private" transactions and which may under certain
circumstances be applicable to the Merger or another business combination
following the purchase of Shares pursuant to the Offer in which we seek to
acquire the remaining Shares not held by us. We believe, however, that Rule
13e-3 will not be applicable to the Merger because it is anticipated that the
Merger would be effected within one year following consummation of the Offer and
in the Merger, shareholders would receive the same price per Share as paid in
the Offer. If Rule 13e-3 were applicable to the Merger, it would require, among
other things, that certain financial information concerning the Company, and
certain information relating to the fairness of the proposed Transactions and
the consideration offered to minority shareholders in such a transaction, be
filed with the SEC and disclosed to minority shareholders prior to consummation
of the Transactions.

13.  SOURCE AND AMOUNT OF FUNDS

     We estimate that the total amount of funds required to purchase all Shares
pursuant to the Offer and Merger and to pay to the holders of outstanding
Comshare stock options the amounts required under the Merger Agreement will be
approximately $52 million. Geac will ensure that sufficient funds are available
to acquire all of the outstanding Shares pursuant to the Offer and the Merger
and to pay all amounts required to be paid to the holders of outstanding
Comshare stock options. The Offer is not conditioned upon Geac's or Purchaser's
ability to finance the purchase of Shares pursuant to the Offer.

14.  DIVIDENDS AND DISTRIBUTIONS

     The Merger Agreement provides that the Company will not, and will not
permit any of its subsidiaries to, between the date of the Merger Agreement and
the Effective Time without the prior consent of Geac, make, declare, set aside
or pay any dividend or other distribution with respect to any shares of its
capital stock, other than dividends and other distributions paid by any such
subsidiary to the Company or any other wholly-owned subsidiary of the Company.

15.  CERTAIN CONDITIONS OF THE OFFER

     For the purposes of this Section 15, capitalized terms used but not defined
herein will have the meanings set forth in the Merger Agreement. Notwithstanding
any other provisions of the Offer, we will not be required to accept for payment

14e-1(c) under the Exchange Act, pay for any tendered Shares, and may delay the

existing in foreign jurisdictions has not expired or been terminated; (iii)

          (a) there shall be pending any suit, action or proceeding by any
     Governmental Entity (i) seeking to prohibit or impose any material
     limitations on Geac's or Purchaser's ownership or operation (or that of any
     of their respective subsidiaries or affiliates) of all or a material
     portion of the Company's businesses or assets, (ii) seeking to compel Geac
     or Purchaser or their respective subsidiaries and affiliates to dispose of
     or hold separate any material portion of the business or assets of the
     Company and its subsidiaries, taken as a whole, (iii) challenging the
     acquisition by Geac or Purchaser of any Shares pursuant to the Offer or the
     Merger, (iv) seeking to restrain or prohibit the making or consummation of

     full rights of ownership of the Shares, including, without limitation, the
     right to vote the Shares purchased by it on all matters properly presented
     to the Company's shareholders; or

          (b) there has been any statute, rule, regulation, injunction, order or
     decree enacted, enforced, promulgated, issued or deemed applicable to the
     Offer or the Merger by any Governmental Entity that results in any of the
     consequences referred to in clauses (i) or (ii) of paragraph (a) above; or

          (c) any representation or warranty of the Company contained in the
     Merger Agreement (disregarding all qualifications and exceptions contained
     therein relating to materiality or Material Adverse Effect or any similar
     standard or qualification) shall not be true and correct in all respects as
     of the Determination Time, as if made at and as of such time (except to the
     extent that any such representation or warranty, by its terms, is expressly
     limited to a specific date, in which case such representation or warranty
     shall not be true and correct as of such date), and the failure of such
     representation or warranty to be true and correct would reasonably be
     expected to have a Material Adverse Effect on the Company, provided that
     such breach is incapable of being cured or has not been cured prior to the
     initial expiration date of the Offer (or such later date upon which the
     Offer shall expire in accordance with Section 2.01 of the Merger

     modified in a manner adverse to Geac or Purchaser (including by amendment
     of the Schedule 14D-9) its approval or recommendation of the Offer, the
     Merger or the Merger Agreement or recommended or approved any Acquisition
     Proposal,

          and, in the reasonable good faith judgment of Geac or Purchaser, the
     condition or event described in the foregoing paragraphs (a) through (e),
     regardless of the circumstances giving rise to such event or condition,
     makes it inadvisable to proceed with the Offer or the acceptance for
     payment of or payment for the Shares; provided, in any such case, that
     Purchaser and Geac have performed all of their respective obligations under
     Section 9.01 of the Merger Agreement.

     A public announcement may be made of a material change in, or waiver of,
such conditions and the Offer may, in certain circumstances, be extended in
connection with any such change or waiver. See Section 1.

16.  LEGAL MATTERS; REQUIRED REGULATORY APPROVALS

     Except as set forth in this Offer to Purchase, we are not aware of any
licenses or regulatory permits that appear to be material to the business of the
Company and its subsidiaries, taken as a whole, and that might be adversely
affected by our acquisition of Shares (and the indirect acquisition of the stock
of the Company's subsidiaries) in the Offer, or any filings, approvals or other
actions by or with any domestic, foreign or supranational governmental authority
or administrative or regulatory agency that would be required prior to our
acquisition or ownership of the Shares (or the indirect acquisition of the stock
of the Company's subsidiaries). Should any such approval or other action be
required, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to the Company's or its subsidiaries' business, or
that certain parts of the Company's or Geac's or any of their respective
subsidiaries' business might not have to be disposed of or held separate or
other substantial conditions complied with in order to obtain such approval or
action or in the event that such approvals were not obtained or such actions
were not taken. Purchaser's obligation to purchase and pay for Shares is subject
to certain conditions, including conditions with respect to governmental
actions. See the Introduction and Section 15 for a description of certain
conditions to the Offer, including with respect to litigation and governmental
actions.

     State Takeover Laws.  A number of states (including Michigan, where the
Company is incorporated) have adopted takeover laws and regulations which
purport, to varying degrees, to be applicable to attempts to acquire securities
of corporations which are incorporated in those states or that have substantial
assets, security holders, principal executive offices or principal places of
business in those states. To the extent that these state takeover statutes
purport to apply to the Offer, we believe that such laws conflict with federal
law and constitute an unconstitutional burden on interstate commerce. In the
Merger Agreement, the Company represented to Geac and the Purchaser that:

     - the Company has taken all action necessary, if any, to exempt the Offer,
       the Merger and the Merger Agreement and the Transactions from the
       provisions of Section 775 through 784 of Michigan Law in order to render
       the provisions of such statutes requiring supermajority approval of
       certain business combinations inapplicable to Shares acquired by Geac,
       Purchaser or their respective affiliates pursuant to the Offer and the
       Merger;

     - the Company has taken all action necessary to opt out of Sections 790
       through 799 of Michigan Law in order to render the provisions of such
       statutes restricting voting rights of "control shares" inapplicable to
       Shares acquired by Geac, Purchaser or their respective affiliates
       pursuant to the Offer and the Merger;

     - no other anti-takeover, control share acquisition, fair price, moratorium
       or other similar statute (each, a "Takeover Statute") applies or purports
       to apply to the Merger Agreement, the Offer, the Merger, the Voting
       Agreement, the Top-Up Option or the Transactions;

     - the Company has taken all action necessary to render the Rights
       inapplicable to the Transactions, including the Offer and the Merger; and

     - the Rights Agreement has been amended by all necessary action to (i)
       render the Rights Agreement inapplicable to the Merger Agreement, the
       Offer, the Merger, the Voting Agreement, the Top-Up Option and the
       Transactions, (ii) ensure that (x) none of Geac, Purchaser or their
       respective affiliates is an "Acquiring Person" (as defined in the Rights
       Agreement) by virtue of the execution, delivery, announcement or
       performance of the Merger Agreement, the Offer, the Merger, the Voting
       Agreement, the Top-Up Option or the Transactions and (y) none of a
       "Distribution Date", a "Share Acquisition Date", or a "Triggering Event"
       (as such terms are defined in the Rights Agreement) occurs by reason of
       the execution, delivery, announcement, consummation or performance of the
       Merger Agreement, the Offer, the Merger, the Voting Agreement, the Top-Up
       Option or the Transactions, and such amendment by its terms may not be
       further amended by the Company without the prior written consent of Geac
       in its sole discretion.

                                        40


     Except as described herein, we have not attempted to comply with any state
takeover statutes in connection with the Offer or the Merger. We reserve the
right to challenge the validity or applicability of any state law allegedly
applicable to the Offer or the Merger and nothing in this Offer to Purchase nor
any action taken in connection with the Offer or the Merger is intended as a
waiver of that right. In the event that any state takeover statute is found
applicable to the Offer or the Merger, and it is not determined by an
appropriate court that the statutes in question do not apply or are invalid as
applied to the Offer, we may be required to file certain documents with, or
receive approvals from, the relevant state authorities, and we may be unable to
accept for payment or purchase Shares tendered in the Offer or be delayed in
continuing or consummating the Offer. In that case, we may not be obligated to
accept for purchase, or pay for, any Shares tendered. See Section 15.

     Antitrust.  Under the HSR Act, and the rules and regulations that have been
issued by the FTC, certain acquisition transactions may not be consummated until
certain information and documentary material has been furnished for review by
the Antitrust Division and the FTC and certain waiting period requirements have
been satisfied. The acquisition of Shares pursuant to the Offer is, and the
proposed Merger may be, subject to these requirements. Purchaser intends to file
a Premerger Notification and Report Form with the Antitrust Division and the FTC
in connection with the purchase of Shares pursuant to the Offer.

     Under the HSR Act, the purchase of Shares in the Offer may not be completed
until the expiration of a 15-calendar-day waiting period following the filing by
the Purchaser of the Premerger Notification and Report Form with the FTC and
Antitrust Division, unless the waiting period is earlier terminated by the FTC
and the Antitrust Division or we receive a Request for Additional Information
and Documentary Material from the Antitrust Division or the FTC prior to that
time. If either the FTC or the Antitrust Division were to issue a Request for
Additional Information and Documentary Material to us, the waiting period with
respect to the Offer would expire at 11:59 p.m., Eastern time, on the tenth
calendar day after the date of our substantial compliance with that request.
Thereafter, the waiting period could be extended only by court order or with our
consent. The additional 10-calendar-day waiting period may be terminated sooner
by the FTC and the Antitrust Division. Although the Company is required to file
certain information and documentary material with the Antitrust Division and the
FTC in connection with the Offer, neither the Company's failure to make those
filings nor the issuance to the Company by the FTC or the Antitrust Division of
a Request for Additional Information and Documentary Material will extend the
waiting period with respect to the Offer.

     The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions, such as our acquisition of Shares in the
Offer and the proposed Merger. At any time before or after our purchase of
Shares, the Antitrust Division or the FTC could take such action under the
antitrust laws that either deems necessary or desirable in the public interest,
including seeking to enjoin the purchase of Shares in the Offer, the divestiture
of Shares purchased pursuant to the Offer or the divestiture of substantial
assets of the Company or Geac or any of their respective subsidiaries. Private
parties as well as state attorneys general may also bring legal actions under
the antitrust laws under certain circumstances. See Section 15.

     State antitrust authorities and private parties in certain circumstances
may bring legal action under the antitrust laws seeking to enjoin the Offer or
the Merger or to impose conditions on the Offer or the Merger. See "Efforts"
discussed above in Section 12.

     Geac and the Company each conduct operations in a number of foreign
jurisdictions other than the U.S. and filings may have to be made with foreign
governments under their respective pre-merger notification statutes. Where
necessary, the parties intend to make such filings.

     In addition, Geac and the Company conduct operations in a number of other
countries where regulatory filings or approvals may be required in connection
with the consummation of the Merger.

18.  MISCELLANEOUS

behalf of) holders of Shares residing in any jurisdiction in which the making of
the Offer or the acceptance thereof would not be in compliance with the

own discretion, take any action as we may deem necessary to make the Offer in
any jurisdiction and extend the Offer to holders of Shares in those
jurisdictions.

     In any jurisdiction where the securities, blue sky or other laws require
the Offer to be made by a licensed broker or dealer, the Offer will be deemed to

with respect to information concerning the Company.

     We have not authorized any person to give any information or to make any
representation on our behalf not contained in this Offer to Purchase or in the
Letter of Transmittal and, if given or made, you should not rely on any such
information or representation as having been authorized. Neither the delivery of
the Offer to Purchase nor any purchase pursuant to the Offer will, under any
circumstances, create any implication that there has been no change in the
affairs of Geac, Purchaser, the Company or any of their respective subsidiaries
since the date as of which information is furnished or the date of this Offer to
Purchase.
