Dear Information Advantage Stockholder:
 
     As many of you are aware, Information Advantage, Inc. has entered into an
agreement to acquire IQ Software Corporation. You are cordially invited to
attend a Special Meeting of Stockholders of Information Advantage to be held at
the Marquette Hotel, located at 710 Marquette Avenue, Minneapolis, Minnesota, on
September 23, 1998 at 10:00 a.m. local time. At the Special Meeting, you will be
asked to vote on a proposal to approve the issuance of Information Advantage
common stock to IQ Software stockholders in connection with the merger of IQ
Software with a wholly-owned subsidiary of Information Advantage.
 
     Your Board of Directors believes that the acquisition of IQ Software will
result in a combined company with significantly greater resources and the
opportunity to market a more complete product offering than Information
Advantage alone. We further believe that the acquisition of IQ Software will
enable Information Advantage to enhance its competitive position as a leader in
relational on-line analytical processing software.
 
     The merger of the two companies will be effected by the issuance of 1.96
shares of Information Advantage common stock for each share of IQ Software
common stock. Each share of Information Advantage common stock will remain
outstanding and will represent one share of the combined company.
 
     If the requisite approvals of the stockholders of Information Advantage and
IQ Software are received, the merger is expected to be consummated on or about
September 24, 1998.
 
     YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AND THE
TRANSACTIONS RELATED THERETO AND HAS UNANIMOUSLY DETERMINED THAT THEY ARE FAIR
TO AND IN THE BEST INTERESTS OF INFORMATION ADVANTAGE AND ITS STOCKHOLDERS.
AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
STOCKHOLDERS VOTE FOR THE MERGER PROPOSAL.
 
     In the material accompanying this letter, you will find a Notice of Special
Meeting of Stockholders, a Joint Proxy Statement/Prospectus relating to the
actions to be taken by Information Advantage stockholders at the Special
Meeting, copies of the IQ Software Annual Report on Form 10-K for the year ended
January 31, 1998 and its Quarterly Report on Form 10-Q for the quarter ended
April 30, 1998 and a proxy card. The Joint Proxy Statement/Prospectus more fully
describes the merger proposal and includes information about Information
Advantage and IQ Software.
 
     ALL STOCKHOLDERS ARE INVITED TO ATTEND THE SPECIAL MEETING IN PERSON.
WHETHER OR NOT YOU EXPECT TO ATTEND THE SPECIAL MEETING IN PERSON, PLEASE
COMPLETE, DATE AND SIGN THE ENCLOSED PROXY AND RETURN IT WITHOUT DELAY IN THE
ENCLOSED ENVELOPE, WHICH REQUIRES NO ADDITIONAL POSTAGE IF MAILED IN THE UNITED
STATES. IF YOU ATTEND THE SPECIAL MEETING, YOU MAY THEN WITHDRAW YOUR PROXY AND

                            ------------------------
 
    This Joint Proxy Statement/Prospectus of Information Advantage, Inc., a
Delaware corporation ("IA"), and IQ Software Corporation, a Georgia corporation
("IQ"), is being used (a) to solicit proxies on behalf of the IA Board of
Directors (the "IA Board") from holders of the outstanding IA common stock, $.01
par value ("IA Common Stock"), in connection with the Special Meeting of
Stockholders of IA to be held at the Marquette Hotel, 710 Marquette Avenue,
Minneapolis, MN, on September 23, 1998 at 10:00 a.m., local time (the "IA
Special Meeting"), and (b) to solicit proxies on behalf of the IQ Board of
Directors (the "IQ Board") from holders of the outstanding IQ common stock,
$.00033 par value ("IQ Common Stock"), in connection with a Special Meeting of
Stockholders of IQ to be held at the IQ principal executive offices, 3295 River
Exchange Drive, Suite 550, Norcross, GA 30092, on September 23, 1998 at 10:00
a.m., local time (the "IQ Special Meeting"). This Joint Proxy
Statement/Prospectus and the accompanying proxies are first being mailed to
stockholders of IA and stockholders of IQ on or about August 24, 1998.
 
    At the IA Special Meeting, stockholders of IA will be asked (1) to consider
and vote upon a proposal (the "IA Merger Proposal") to approve the issuance of
shares of IA Common Stock to the stockholders of IQ pursuant to the terms of an
Agreement and Plan of Merger, as amended, (the "Plan of Merger") dated as of
June 29, 1998, by and among IA, IQ and IAC Merger Corp., a Georgia corporation
and wholly-owned subsidiary of IA ("Merger Sub"), pursuant to which, among other
things, (a) Merger Sub will be merged with and into IQ (the "Merger"); (b) each
share of IQ Common Stock outstanding as of the closing of the Merger (other than
shares that are owned by IA or IQ or any subsidiary of IQ) will be converted
into the right to receive 1.96 shares of IA Common Stock (the "Exchange Ratio");
(c) all outstanding IQ stock options, together with the underlying IQ stock
option plans (collectively, the "IQ Stock Plans") , will be assumed by IA and
converted at the Exchange Ratio into options to purchase shares of IA Common
Stock and (d) IQ will become a wholly-owned subsidiary of IA; and (2) to
transact such other business as may properly come before the IA Special Meeting
or any adjournments or postponements thereof.
 
    At the IQ Special Meeting, stockholders of IQ will be asked to (1) consider
and vote upon a proposal (the "IQ Merger Proposal") to approve the Merger and
Plan of Merger, pursuant to which, among other things, (a) Merger Sub will be
merged with and into IQ, (b) each share of IQ Common Stock outstanding as of the
closing of the Merger (other than shares that are owned by IA or IQ or
subsidiary of IQ) will be converted into the right to receive 1.96 shares of IA
Common Stock (the "Exchange Ratio"), (c) all IQ stock options, together with the
IQ Stock Plans, will be assumed by IA and converted into options to purchase
shares of IA Common Stock, and (d) IQ will become a wholly owned subsidiary of
IA and (2) to transact such other business as may properly come before the IQ
Special Meeting or any adjournments or postponements thereof.
 
    Based upon the number of outstanding shares of IA Common Stock and IQ Common
Stock as of August 14, 1998 (the record date for the IA Special Meeting and the
IQ Special Meeting), the shares of IA Common Stock issued to IQ stockholders in
the Merger (and issuable with respect to outstanding IQ stock options) would
represent approximately 36.4% of the outstanding shares of IA Common Stock
(including shares issuable by IA and IQ upon the exercise of outstanding options
to purchase shares of IA Common Stock and IQ Common Stock) immediately following
the closing of the Merger.
 
    This Joint Proxy Statement/Prospectus also constitutes the prospectus of IA
under the Securities Act of 1933, as amended (the "Securities Act"), for the
offering of shares of IA Common Stock in connection with the Merger. IA Common
Stock and IQ Common Stock are traded on the Nasdaq National Market under the
symbols "IACO" and "IQSW," respectively. On August 19, 1998, the closing sale
prices of the IA Common Stock and IQ Common

Stock as reported on the Nasdaq National Market were $6.625 and $11.25 per
share, respectively. The information set forth in this Joint Proxy
Statement/Prospectus concerning IA and Merger Sub has been furnished by IA, and
the information set forth in this Joint Proxy Statement/Prospectus concerning IQ
has been furnished by IQ. The current market quotations for the IA Common Stock

THE MERGER
 
     General. At the time and on the date the Certificate of Merger is filed
with the Office of the Secretary of State of the State of Georgia (the
"Effective Time" or "Closing Date" of the Merger), (a) Merger Sub will be merged
with and into IQ, (b) the separate existence of Merger Sub will cease and (c) IQ
will become a wholly owned subsidiary of IA. In addition, at the Effective Time
of the Merger, (a) each share of IQ Common Stock outstanding as of the closing
of the Merger (other than shares that are owned by IA or IQ or any subsidiary of
IQ) will be converted into the right to receive 1.96 shares of IA Common Stock;
and (b) all IQ stock options, together with the underlying IQ Stock Plans, will
be assumed by IA and converted into options to purchase shares of IA Common
Stock at an exercise price based upon the Exchange Ratio. Each share of IA
Common Stock will remain outstanding and will represent one share of the
combined company. The vesting of certain stock options issued to IQ executive
officers under the IQ Stock Plans will accelerate, by their terms, automatically
upon consummation of the Merger. See "The Merger and Related Transactions -- IQ
Stock Option Plans."
 
     No fractional shares of IA Common Stock will be issued in the Merger.
Instead, cash will be paid in lieu of the issuance of fractional shares. See
"The Merger and Related Transactions -- Conversion of IQ Shares."
 
     Assuming that all conditions to the Merger are met or waived prior thereto,
and that the IA Merger Proposal and the IQ Merger Proposal are approved, it is
anticipated that the Effective Time of the Merger will
 
                                        2
<PAGE>   16
 
occur promptly following the IA Special Meeting and the IQ Special Meeting. The
current market quotations for the IA Common Stock and the IQ Common Stock may be
obtained on the World Wide Web at http://www.nasdaq.com.
 
     Based on the number of shares of IQ Common Stock outstanding as of August
14, 1998, an aggregate of up to 9,177,633 shares of IA Common Stock will be
issued in the Merger. In addition, IA will assume outstanding stock options to
purchase an aggregate of 664,275 shares of IQ Common Stock (based on the number
of shares subject to outstanding IQ stock options on August 14, 1998), which, as
adjusted to give effect to the Exchange Ratio, will become options to purchase
an aggregate of approximately 1,301,979 shares of IA Common Stock. The
conversion will be effected by multiplying the number of shares of IQ Common
Stock subject to each IQ stock option immediately prior to the Merger by the
Exchange Ratio and dividing the exercise price of each such option by the
Exchange Ratio. If a holder of an IQ stock option were to exercise such option
before the Effective Time of the Merger, each share of IQ Common Stock issued
pursuant to such option will be converted into the right to receive 1.96 shares
of IA Common Stock. As soon as practicable after the Closing Date, IA will file
a Registration Statement on Form S-8 with respect to the shares of IA Common
Stock issuable with respect to IQ stock options assumed by IA pursuant to the
Merger. See "The Merger and Related Transactions -- IQ Stock Option Plans."
 
     The following table presents the equity interests in the combined company
of IA stockholders and IQ stockholders on a pro forma combined basis as of
August 14, 1998 (including shares issuable by IA and IQ upon the exercise of
outstanding options to purchase shares of IA Common Stock and IQ Common Stock):

     Material Contacts and Board Deliberations. From January 1998, to June 25,
1998 senior executives of IA and IQ met at various times to discuss potential
business relationships. At such meetings beginning in June 1998, senior
executives of IA and IQ, and their respective financial representatives,
tentatively agreed upon a transaction structure and terms, including a
preliminary exchange ratio. In addition, throughout June 1998 senior management
of IA and IQ, and their respective financial, legal and accounting advisors,
conducted due diligence reviews. On June 26, 1998 (in the case of the IQ Board)
and June 28, 1998 (in the case of the IA Board), the respective boards of
directors met separately at which time each Board unanimously concluded that the
Merger was fair and in the best interests of their respective companies and
stockholders and approved and adopted the Plan of Merger, a copy of which is
attached hereto as Appendix A. The Plan of Merger was executed by IA and IQ on
June 29, 1998 and amended on July 24, 1998 in order to effect certain technical
changes. For a more detailed discussion of the background of the Merger, see
"The Merger and Related Transactions -- Material Contacts and Board
Deliberations."

THE IA MERGER PROPOSAL.

     THE IQ BOARD UNANIMOUSLY APPROVED THE IQ MERGER PROPOSAL AND RECOMMENDS
THAT HOLDERS OF IQ COMMON STOCK VOTE FOR THE IQ MERGER PROPOSAL.
 
     Both the IA Board and the IQ Board considered many factors in reaching
their conclusion to approve the Plan of Merger and the Merger and to recommend
that stockholders vote for approval of the IA Merger Proposal and the IQ Merger
Proposal, respectively. See "The Merger and Related Transactions -- Reasons for
the Merger" and "-- Interests of Certain Persons."
 
     Opinion of IA Financial Advisor. On June 28, 1998, BancAmerica Robertson
Stephens LLP ("BancAmerica Robertson Stephens") delivered its written opinion
(the "BancAmerica Robertson Stephens Opinion") to the IA Board that, as of such
date, and based on the procedures followed, factors considered and assumptions
made as set forth therein, the Exchange Ratio pursuant to the Plan of Merger was
fair from a financial point of view to IA. The full text of the BancAmerica
Robertson Stephens Opinion, which sets forth the assumptions made, procedures
followed, matters considered and limitations on the review undertaken, is
attached as Appendix B to this Joint Proxy Statement/Prospectus and should be
read carefully and in its entirety in connection with this Joint Proxy
Statement/Prospectus. The BancAmerica Robertson Stephens Opinion is directed to
the IA Board, addresses only the fairness to IA as of June 28, 1998, from a
financial point of view, of the Exchange Ratio pursuant to the Plan of Merger
and does not constitute a recommendation to any holder of IA Common Stock as to
how such stockholder should vote at the IA Special Meeting. A summary of all
material provisions of the BancAmerica Robertson Stephens Opinion is set forth
in this Joint Proxy Statement/Prospectus and such summary is qualified in its
entirety by reference to the full text of such opinion. See "The Merger and
Related Transactions -- Opinion of IA Financial Advisor" and "Appendix B."
 
     Opinion of IQ Financial Advisor. First Albany Corporation ("First Albany")
has rendered a written opinion (the "First Albany Opinion") to the IQ Board
that, as of June 26, 1998, and based on the procedures followed, factors
considered and assumptions made as set forth therein, the Exchange Ratio
pursuant to the Plan of Merger was fair from a financial point of view to the
holders of IQ Common Stock. The full text of the First Albany Opinion, which
sets forth the assumptions made, procedures followed, matters considered and
limitations on the review undertaken, is attached as Appendix C to this Joint
Proxy Statement/Prospectus and should be read carefully and in its entirety in
connection with this Joint Proxy Statement/Prospectus. The First Albany Opinion
was provided to the IQ Board in connection with its consideration of the Merger
and does not constitute a recommendation as to how any holder of IQ Common Stock
should vote at the IQ Special Meeting. A summary of all material elements of the
First Albany Opinion is set forth in this Joint Proxy Statement/Prospectus and
such summary is qualified in its entirety by reference to the full text of such
opinion. See "The Merger and Related Transactions -- Opinion of IQ Financial
Advisor" and "Appendix C."
 
     Representations and Warranties and Certain Covenants. Under the Plan of
Merger, IA and IQ made a number of representations and warranties regarding
their respective capital structures, operations, financial conditions and other
matters. IQ has agreed that, until the closing of the Merger or the termination
of the Plan of Merger, it will (a) carry on its business in the ordinary course
and attempt to preserve its present business and relationships with customers,
suppliers and others, and (b) not take certain actions without IA's consent.
Each of IA and IQ have agreed to use its best efforts to complete the Merger.
See "The Merger and Related Transactions -- Representations and Warranties" and
"-- Certain Covenants."
 
     No Solicitation. IQ has agreed not to solicit, initiate discussions with or
engage in negotiations with any person relating to a possible acquisition of IQ,
except that if the IQ Board receives an unsolicited Acquisition Proposal (as
defined in the Plan of Merger) that it believes in its good faith reasonable
judgment (based upon and consistent with advice received in consultation with
independent financial and legal advisors) is reasonably capable of being
completed on the terms proposed and, after taking into account the strategic
benefits anticipated to be derived from the Merger and the long-term prospects
of IA and IQ as a combined company, would, if consummated, result in a
transaction more favorable over the long term from a financial point of view
than the Merger, then the IQ Board will not be prevented from providing
information or entering into such discussions or negotiations with the party
making the Superior Proposal (as defined in the Plan of Merger) or recommending
the Superior Proposal to IQ Stockholders, as may be necessary to discharge the
directors' fiduciary duties. See "The Merger and Related Transactions -- No
Solicitation."

     Resale of IA Common Stock; Agreements with Affiliates. The shares of IA
Common Stock to be issued in the Merger have been registered under the
Securities Act and, except as set forth below, will be freely transferable. As a
condition to the obligations of the parties under the Plan of Merger, IA and IQ
have each received agreements from each person or entity who may be deemed an
affiliate (as defined in the Securities Act and the rules and regulations
thereunder) of IA or IQ, pursuant to which such persons have agreed not to sell,
transfer or otherwise dispose of shares of IA Common Stock or IQ Common Stock
for 30 days prior to the Effective Time and until such time after the Effective
Time as IA has publicly released a report including financial results for a
period of at least 30 days of combined operations of IA and IQ. Furthermore,
pursuant to such agreements, the affiliates of IQ have agreed to refrain from
the sale or transfer of any IA Common Stock received in connection with the
Merger, except in accordance with the provisions of the Securities Act and the
general rules and regulations thereunder. See "The Merger and Related
Transactions -- Resale of IA Common Stock; Agreements with Affiliates."
 
     Interests of Certain Persons in the Merger. As a result of the transactions
and agreements set forth below, the directors and executive officers of IQ have
personal interests in the Merger and Plan of Merger that are not identical to
the interests of IQ stockholders.
 
     As of the IQ Record Date, directors and executive officers of IQ and their
affiliates beneficially owned an aggregate of 532,104 shares of IQ Common Stock
(excluding 74,750 shares of IQ Common Stock subject to unexercised stock
options). Based on the last reported sales price of IA Common Stock on August
19, 1998 of $6.625, the aggregate dollar value of the shares of IA Common Stock
to be received in the Merger, excluding shares subject to stock options, by the
executive officers and directors of IQ and their affiliates is approximately
$6.9 million.
 
     The directors and executive officers of IQ have agreed to vote all shares
of IQ Common Stock under their control in favor of the IQ Merger Proposal and
have executed voting agreements and granted irrevocable proxies to IA. See "The
Merger and Related Transactions -- Voting Agreements."
 
     The Plan of Merger provides that Charles R. Chitty, the Chairman of the
Board, President and Chief Executive Officer of IQ shall become a member of the
IA Board following the Effective Time. In addition, Mr. Chitty will enter into a
one-year employment agreement to be followed by a two-year consulting
arrangement with IA, effective upon the Effective Time. See "The Merger and
Related Transactions -- Employment Agreement."
 
     Certain of the outstanding stock option agreements held by IQ executive
officers, provide for the acceleration of existing vesting provisions in the
event of a change of control of IQ, such as the Merger. As a result of these
provisions, options to purchase an additional 45,000 shares of IQ Common Stock
will vest on the Effective Date. See "The Merger and Related Transactions -- IQ
Stock Option Plans."
 
     Pursuant to the Plan of Merger, IA has agreed that the surviving
corporation shall indemnify each person who was an officer or director of IQ
against certain liabilities. See "The Merger and Related Transactions --
Director and Officer Indemnification."
 
     Indemnification of IQ Officers and Directors. IA has agreed that, after the
Effective Time of the Merger, the surviving corporation will indemnify each
present and former officer and director of IQ as provided in the General
Business Corporation Code of the State of Georgia ("GCC") and the IQ Certificate
of Incorporation and Bylaws. IA is currently a party to indemnification
agreements with its directors, and it is anticipated that the combined company
will enter into similar agreements with its new director following consummation
of the Merger. See "The Merger and Related Transactions -- Director and Officer
Indemnification" and "-- Interests of Certain Persons."
 
     Conditions. The closing of the Merger is subject to various conditions,
including the approval by IA's stockholders of the IA Merger Proposal; the
approval by IQ's stockholders of the IQ Merger Proposal; receipt of opinions of
counsel to the effect that the Merger will qualify as a reorganization (a
"Reorganization") under Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"); (see "-- Certain Federal Income Tax Considerations"); and
receipt of a letter from PricewaterhouseCoopers LLP ("PricewaterhouseCoopers"),
independent auditors to IA, and a letter from Ernst & Young LLP ("Ernst &
 
                                        5
<PAGE>   19
 
Young"), independent auditors to IQ, stating that the Merger will qualify as a
pooling of interests under Accounting Principles Board Opinion No. 16. Except
for matters required by law, each of the parties to the Plan of Merger may, at
its option, waive compliance with any condition to its obligation to consummate
the Merger. See "The Merger and Related Transactions -- Conditions" and
"-- Accounting Treatment" and "Risk Factors -- Pooling of Interests."
 
     Termination; Termination Fees and Expenses. The Plan of Merger may be
terminated (a) by mutual agreement of IA and IQ; (b) by either IA or IQ if the
closing of the Merger has not occurred on or before November 30, 1998 (the
"Outside Date"); or (c) by either IA or IQ before the Outside Date upon the
occurrence of certain events. See "The Merger Agreement and Related
Transactions -- Termination; Termination Fees and Expenses."
 
     Under certain circumstances, IA may be required to reimburse IQ for
expenses up to $450,000. IQ may also be required under certain circumstances to
pay IA a termination fee of $2,240,000 if the Plan of Merger is terminated. In
addition, IA's right to exercise its option to purchase shares of IQ Common
Stock will be triggered if the Plan of Merger is terminated under certain
circumstances. See "The Merger and Related Transactions -- Termination;
Termination Fees and Expenses" and "-- Stock Option Agreement."
 
     Closing. The Merger will be completed on the date that the Certificate of
Merger is filed with the Office of the Secretary of State of the State of
Georgia. The Effective Time is expected to occur as soon as practicable after
receipt of the necessary approvals at the IA Special Meeting and the IQ Special
Meeting and satisfaction or waiver of the other conditions precedent to the
Merger, as set forth in the Plan of Merger (the "Closing"). It is anticipated
that the Closing will occur promptly following receipt of the necessary
approvals at the IA Special Meeting and the IQ Special Meeting. See "The Merger
and Related Transactions -- Closing."
 
     Amendment and Waiver. The Plan of Merger may be amended by the agreement of
the IA and IQ Boards at any time before or after approval by the IA stockholders
or the IQ stockholders, except that, after such approval, no amendment may be
made which by law requires further approval by such stockholders without such
further approval. See "The Merger and Related Transactions -- Amendment and
Waiver."
 
     Stock Option Agreement. IA and IQ have entered into a Stock Option
Agreement, dated June 29, 1998, pursuant to which (i) IA has the right, under
certain circumstances, to purchase up to 930,169 shares of IQ Common Stock (or
approximately 19.9% of the outstanding IQ Common Stock as of June 29, 1998 prior
to giving effect to such issuance) at a price based on the market price of IQ
Common Stock (the "Stock Option Agreement"). The Stock Option Agreement contains
features which, among other things, (a) permit IA to receive a cash payment in
lieu of stock upon exercise of the option and (b) limit the profit which IA can
realize in connection with the option to $3,200,000, inclusive of any
termination fees that IA may receive pursuant to the Plan of Merger. If the
Merger is consummated, the Stock Option Agreement will terminate by its terms.
See "The Merger and Related Transactions -- Stock Option Agreement."
 
     Certain Federal Income Tax Considerations. As a condition to the
consummation of the Merger, IA and IQ will receive opinions from Gunderson
Dettmer Stough Villeneuve Franklin & Hachigian, LLP ("Gunderson Dettmer") and
Miller & Martin LLP ("Miller & Martin"), respectively, that the Merger will be
treated for federal income tax purposes as a Reorganization if the Merger is
consummated in accordance with the terms of the Plan of Merger. Provided that
the Merger does qualify as a Reorganization, no gain or loss should be
recognized for federal income tax purposes by IQ stockholders upon their receipt
of shares of IA Common Stock in exchange for their shares of IQ Common Stock,
except to the extent of cash received in lieu of fractional shares. Such legal
opinions have been filed as exhibits to the Registration Statement of which this
Joint Proxy Statement/Prospectus is a part, are subject to certain limitations
and qualifications and are based upon certain factual assumptions and
representations. Furthermore, such legal opinions are not binding on the
Internal Revenue Service. ALL IQ STOCKHOLDERS SHOULD READ CAREFULLY THE
DISCUSSION UNDER "THE MERGER AND RELATED TRANSACTIONS -- CERTAIN FEDERAL INCOME
TAX CONSIDERATIONS." IN VIEW OF THE COMPLEXITIES OF FEDERAL INCOME AND OTHER TAX
LAWS, EACH IQ STOCKHOLDER SHOULD CONSULT WITH SUCH STOCKHOLDER'S TAX ADVISOR
REGARDING, AMONG OTHER THINGS, THE FEDERAL,

STATE, LOCAL AND FOREIGN INCOME TAX CONSEQUENCES OF THE MERGER APPLICABLE TO
SUCH STOCKHOLDER'S SPECIFIC CIRCUMSTANCES.
 
     The Merger will not have any United States federal tax consequences for IA
stockholders. See "The Merger and Related Transactions -- Certain Federal Income
Tax Considerations."
 
     Accounting Treatment. The Merger is expected to be accounted for as a
pooling of interests in accordance with the provisions of Accounting Principles
Board Opinion No. 16. Under this method of accounting, the recorded assets and
liabilities of IA and IQ will be carried forward to the combined company at
their recorded amounts, the operating results of the combined company will
include the operating results of IA and IQ for the entire fiscal year in which
the combination occurs, and the reported operating results of the separate
companies for prior periods will be combined and restated as the operating
results of the combined company. It is a condition to the consummation of the
Merger that the Merger qualify as a pooling of interests under Accounting
Principles Board Opinion No. 16. See "The Merger and Related Transactions --
Accounting Treatment" and "Risk Factors -- Pooling of Interests."
 
     No Dissenters' or Appraisal Rights. Holders of IQ Common Stock are not
entitled to dissenters' rights under Section 1302 of the GCC in connection with
the Merger because the IQ Common Stock was listed on the Nasdaq National Market
on the record date for the IQ Special Meeting and the shares of IA Common Stock
to be issued pursuant to the Merger will be listed on the Nasdaq National Market
as of the Effective Time. Holders of IA Common Stock are not entitled to
appraisal rights under Section 262 of the Delaware General Corporation Law
("DGCL") in connection with the Merger because IA is not a constituent
corporation in the Merger.
 
RISK FACTORS
 
     The completion of the Merger and an investment in shares of IA Common Stock
each involve substantial risks. Stockholders of IQ and stockholders of IA should
consider the information set forth in "Risk Factors" and the other information
contained herein before deciding whether or not to approve the IA Merger
Proposal or the IQ Merger Proposal, as applicable.

(1) It is anticipated that IA will incur charges to operations related to the
    Merger, currently estimated to be $7.1 million, principally in the quarter
    during which the Merger is consummated. These charges include direct
    transaction costs, primarily for financial advisory, accounting and legal
    fees, printing expenses, filing fees and other Merger-related costs
    associated with combining the operations of the two companies. The estimated
    charge is reflected in the unaudited pro forma condensed combined balance
    sheet data, but is not reflected in the unaudited pro forma condensed
    combined statement of operations data. This charge is a preliminary estimate
    only, and is therefore subject to change.
 
(2) The unaudited pro forma condensed combined balance sheet as of July 31, 1998
    gives effect to the Merger as if it had occurred on July 31, 1998, and
    combines the unaudited historical consolidated balance sheets of IA and IQ
    as of that date. The unaudited pro forma condensed combined statements of
    operations give effect to the Merger as if it had occurred at the beginning
    of the earliest period presented.

                           COMPARATIVE PER SHARE DATA
 
     The following table sets forth certain historical per share data of IA and
IQ and combined per share data on an unaudited pro forma basis after giving
effect to the Merger on a pooling of interests basis of accounting. The
information set forth below should be read in conjunction with the selected
historical financial data, and the unaudited pro forma condensed combined
financial information, included elsewhere in this Joint Proxy
Statement/Prospectus or incorporated herein by reference. The pro forma combined
per share data are not necessarily indicative of the operating results that
would have been achieved had the Merger been consummated as of the beginning of
the periods presented and should not be construed as representative of future
operating results. Neither IA nor IQ has paid cash dividends during the periods
presented.

                                  RISK FACTORS
 
     This Joint Proxy Statement/Prospectus contains Forward-Looking Statements.
Actual results could differ materially from those projected in the
Forward-Looking Statements as a result of the factors set forth below and other
matters described elsewhere in this Joint Proxy Statement/Prospectus. See
"Forward-Looking Statements." The following risk factors, in addition to the
other information contained or incorporated by reference herein, should be
considered carefully in evaluating the proposals to be considered and voted upon
at each of the IA Special Meeting and the IQ Special Meeting and the acquisition
of the securities offered hereby.
 
UNCERTAINTY RELATING TO INTEGRATION OF MULTIPLE OPERATIONS AND PRODUCT LINES;
MANAGEMENT OF GROWTH
 
     The integration of IA's and IQ's business and personnel following the
Merger presents difficult challenges for the management of the combined company.
Further, both IA and IQ entered into the Plan of Merger with the expectation
that the Merger will result in synergies for the combined company. The combined
company, however, will be more complex and diverse than either IA or IQ
individually, and the combination and continued operation of their business
operations will be difficult. While the management and Boards of both IA and IQ
believe that the combination of IA and IQ can be effected in a manner that will
realize the value of the combined company, the management group of the combined
company has limited experience in combinations of this complexity or size.
Accordingly, there can be no assurance that the process of effecting the
business combination can be effectively managed to realize the synergies
anticipated to result therefrom.
 
     IA and IQ entered into the Plan of Merger, among other reasons, in order to
achieve potential mutual benefits from combining each of their respective
expertise, product lines and distribution channels for the enterprise software
market. Realization of these potential benefits will require, among other
things, integrating the companies' respective product offerings and coordinating
the combined company's sales and marketing and research and development efforts.
IA and IQ each have different systems and procedures in many operational areas
that must be rationalized and integrated. There can be no assurance that such
integration will be accomplished effectively, expeditiously or efficiently. The
difficulties of such integration may be increased by the necessity of
coordinating geographically separated divisions, integrating personnel with
disparate business backgrounds and combining different corporate cultures. The
integration of certain operations following the Merger will require the
dedication of management resources that may temporarily distract attention from
the day-to-day business of the combined company. The business of the combined
company may also be disrupted by employee uncertainty and lack of focus during
such integration. There can also be no assurance that the combined company will
be able to retain all of its key technical, sales and other personnel. Failure
to effectively accomplish the integration of the operations of IA and IQ could
have a material adverse effect on the combined company's business, operating
results and financial condition. Moreover, uncertainty in the marketplace or
customer hesitation relating to the Merger could negatively affect the combined
company's business, operating results and financial condition.
 
     IA has experienced periods of rapid growth and expansion that have placed
and will continue to place significant strains upon its management systems,
resources and personnel. The combined company's ability to compete effectively
and to manage future growth, if any, will require the combined company to
continue to implement and improve operational, financial and management
information systems on a timely basis and to expand, train, motivate and manage
its work force. There can be no assurance that the combined company's personnel,
systems, procedures and controls will be adequate to support the combined
company's operations.
 
     Although IA and IQ believe that beneficial synergies will result from the
Merger, there can be no assurance that the combining of IA's and IQ's
businesses, even if achieved in an efficient and effective manner, will result
in combined results of operations and financial condition superior to that which
would have been achieved by each company independently, or as to the period of
time required to achieve such result. There is no assurance that IA stockholders
or IQ stockholders would not achieve greater returns on their respective
investments were IA or IQ to remain independent companies.

FIXED MERGER CONSIDERATION DESPITE POTENTIAL CHANGES IN STOCK PRICES
 
     Pursuant to the Plan of Merger, each share of IQ Common Stock outstanding
at the close of the Merger will be converted into the right to receive 1.96
shares of IA Common Stock. The Exchange Ratio is a fixed number and will not be
adjusted in the event of any increases or decreases in the price of either IA
Common Stock or IQ Common Stock. The prices of IA Common Stock and IQ Common
Stock at the Effective Time may vary from their respective prices at the date of
this Joint Proxy Statement/Prospectus and at the date of the IA Special Meeting
and the IQ Special Meeting. Such variations may be the result of changes in the
business operations or prospects of IA or IQ, market assessments of the
likelihood that the Merger will be consummated, the timing thereof, the
prospects of the Merger and post-Merger operations, regulatory considerations
and general market and economic conditions among other things. Because the
Effective Time may occur at a date later than the IA Special Meeting and IQ
Special Meeting, there can be no assurance that the prices of IA Common Stock
and IQ Common Stock on the date of the IA Special Meeting and IQ Special Meeting
will be indicative of their respective prices at the Effective Time.
Stockholders of IA and IQ are urged to obtain current market quotations for IA
Common Stock and IQ Common Stock.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the IA Board and IQ Board with respect
to the Merger and the Plan of Merger, IA and IQ stockholders should be aware
that certain members of IQ's management and Board of Directors have interests in
connection with the Merger and the agreements and transactions contemplated
thereby that are in addition to those of IQ stockholders generally. See "The
Merger and Related Transactions -- Interests of Certain Persons in the Merger,"
"-- Employment Agreement," "-- IQ Stock Option Plans" and "-- Director and
Officer Indemnification."
 
COST OF INTEGRATION; TRANSACTION EXPENSES
 
     Transaction costs relating to the Merger and the anticipated combination of
certain operations of IA and IQ are expected to result in one-time charges to
the combined company's earnings. Although it will not be feasible to determine
the actual amount of these charges until the operational and transition plans
are completed, the management of IA believes that the aggregate charge will be
$7.1 million before taxes, although such amount may be increased by
unanticipated additional expenses incurred in connection with the Merger. This
aggregate charge is expected to include the estimated costs associated with
financial advisory, accounting and legal fees, printing expenses, filing fees
and other Merger-related costs. While the exact timing of these expenses cannot
be determined at this time, it is anticipated that this aggregate charge to
earnings will be recorded principally in the quarter in which the Merger is
consummated. See "Unaudited Pro Forma Condensed Combined Financial Statements."
 
SHARES ELIGIBLE FOR PUBLIC SALE
 
     Sales of substantial amounts of IA Common Stock in the public market after
the consummation of the Merger could materially adversely affect prevailing
market prices of IA Common Stock. Except for shares of IA Common Stock to be
received by affiliates of IQ, all the shares of IA Common Stock to be issued in
the Merger will be eligible for immediate sale in the public market. Although
affiliates of IA and IQ have agreed not to sell any shares controlled by them
for a period of time after the Effective Time, such agreements are expected to
expire in November 1998. Thereafter such shares may be sold only subject to
certain limitations under the Securities Act applicable to affiliates of the
combined company. See "The Merger and Related Transactions -- Resale of IA
Common Stock; Agreements with Affiliates" "-- Pooling of Interests."
 
POOLING OF INTERESTS
 
     In order to qualify the Merger as a pooling of interests for accounting and
financial reporting purposes, affiliates of IA and IQ have agreed not to sell,
or otherwise reduce their risk with respect to, any shares of stock, except for
a de minimus number as defined by certain rules and regulations of the SEC, of
either IA or IQ during the period beginning 30 days preceding the Effective Time
and continuing until IA publicly announces
 
                                       15
<PAGE>   29
 
financial results covering at least 30 days of combined operations of IA and IQ.
Assuming that the Merger is completed and the Effective Time occurs on or before
October 1, 1998, it is not expected that such combined financial results would
be published until the latter part of November, 1998. If affiliates of IA or IQ
sell their IA Common Stock or IQ Common Stock despite their contractual
obligation not to do so, the Merger may not qualify for accounting as a pooling
of interests for financial reporting purposes in accordance with generally
accepted accounting principles, which would in turn materially and adversely
affect IA's reported earnings and, potentially, its stock price. See "The Merger
and Related Transactions -- Accounting Treatment."
 
FUTURE ACQUISITION-RELATED RISKS
 
     It is anticipated that a significant component of the combined company's
growth strategy will be the acquisition of complementary businesses, products
and technologies that meet the combined company's criteria for revenues,
profitability, growth potential and operating strategy. The successful
implementation of this strategy depends on the combined company's ability to
identify suitable acquisition candidates, acquire such companies on acceptable
terms and integrate their operations successfully with those of the combined
company. There can be no assurance that the combined company will be able to
identify suitable acquisition candidates or that the combined company will be
able to acquire such candidates on acceptable terms. Moreover, in pursuing
acquisition opportunities the combined company may compete with other companies
with similar growth strategies. Certain of these competitors may be larger and
have greater financial and other resources than the combined company.
Competition for these acquisition targets could also result in increased prices
of acquisition targets and a diminished pool of companies available for
acquisition. Acquisitions involve a number of other risks, including, among
other things, adverse effects on the combined company's reported operating
results from goodwill amortization, acquired in-process technology, stock
compensation expense and increased compensation expense resulting from newly
hired employees, difficulties in managing diverse geographic sales and research
and development operations, the diversion of management attention, potential
disputes with the sellers of acquired entities and the possible failure to
retain key acquired personnel and the impairment of relationships with employees
and strategic partners as a result of such acquisitions or the integration of
new personnel. Due to the foregoing, the combined company's pursuit of an
acquisition strategy or any individual acquisition may have a material adverse
effect on the combined company's business, operating results and financial
condition.
 
     The combined company's future performance will depend on its ability to
integrate any acquired organization, which, even if successful, may take a
significant period of time, will place a significant strain on the combined
company's resources, and could subject the combined company to additional
expenses. As a result, there can be no assurance that the combined company will
be able to integrate acquired businesses successfully or in a timely manner in
accordance with its strategic objectives. If the combined company is unable to
manage acquisition-based growth effectively, the combined company's business,
operating results and financial condition will be materially adversely affected.
 
LIMITED OPERATING HISTORY; LACK OF PROFITABILITY
 
     The combined company's prospects must be considered in light of the risks
and difficulties frequently encountered by companies in the early stage of
development, particularly companies in new and rapidly evolving markets. To
address these risks, the combined company must, among other things, respond to
competitive developments, continue to attract, retain and motivate qualified
personnel, and continue to enhance and improve its products. IA has incurred net
operating losses in each quarter, except the most recent two quarters, since its
inception and it is possible that the combined company will not generate
sufficient net income to fully utilize its net operating loss carryforwards
before they begin to expire in 2007. As of July 31, 1998, IA had an accumulated
deficit of $26.4 million. The combined company expects to incur additional net
losses. IA operating losses have been due in part to the commitment of
significant resources to its technical support, research and development and
sales and marketing organizations. The combined company expects to continue to
devote substantial resources in these areas and, as a result, will need to
recognize significant quarterly revenues to achieve profitability. In
particular, the combined company intends to continue hiring a significant number
of sales and research and development personnel over the balance of fiscal 1999.
Future
 
                                       16
<PAGE>   30
 
operating results will depend on many factors, including, among others, demand
for and acceptance of the combined company's products and services, including
ongoing acceptance of maintenance and other services purchased by existing
customers, the level of product and price competition, the ability of the
combined company to control costs and to develop, market and deploy new
products, the ability of the combined company to expand its direct sales force
and indirect distribution channels both domestically and internationally, the
combined company's success in attracting and retaining key personnel, market
acceptance of OLAP products and the ability of the combined company to
successfully integrate technologies and businesses it may acquire in the future.
Although the revenues of both IA and IQ have increased in recent periods, there
can be no assurance that the combined company's revenues will grow in future
periods or, if they do grow, that they will grow at past rates, or that the
combined company will remain profitable.
 
FLUCTUATIONS IN OPERATING RESULTS
 
     The limited operating history of IA and IQ and the susceptibility of each
company's operating results to significant fluctuations make the prediction of
future operating results for the two companies unreliable and IA and IQ believe
that period-to-period comparisons of their respective operating results are not
necessarily meaningful and should not be relied upon as indications of the
future performance of the combined company. The operating results of both IA and
IQ have in the past, and the operating results of the combined company will in
the future, vary significantly due to factors such as demand for the combined
company's products, unanticipated events or announcements, the size and timing
of significant orders and their fulfillment, the number, timing and significance
of product enhancements and new product announcements by the combined company
and its competitors or changes in pricing policies by the combined company or
its competitors, customer order deferrals in anticipation of enhancements or new
products offered by the combined company or its competitors, the ability of the
combined company to develop, introduce and market new and enhanced versions of
its products on a timely basis, changes in the combined company's level of
operating expenses and its ability to control costs, budgeting cycles of its
customers, product life cycles, software defects and other product quality
problems, hiring needs and personnel changes, changes in the combined company's
sales incentive plans, changes in the mix of domestic and international
revenues, the level of international expansion, foreign currency exchange rate
fluctuations, performance of indirect channel partners, changes in the mix of
indirect channels through which the combined company's products are offered, the
impact of consolidation by competitors and indirect channel partners and general
domestic and international economic and political conditions, among other
things. A significant portion of IA's revenues have been, and it is expected
that a significant portion of the combined company's revenues will continue to
be, derived from a limited number of orders placed by large organizations. The
timing of such orders and their fulfillment have caused, and are expected to
continue to cause, material fluctuations in the combined company's operating
results, particularly on a quarterly basis. A significant portion of revenues of
both IA and IQ, equalling approximately 52% of their combined revenues, are
derived from existing customers, including resellers. To the extent that such
customers no longer require new licenses or ongoing services, the combined
company's business, financial condition and operating results could be
materially adversely affected. Each of IA and IQ have, from time to time, often
recognized a substantial portion of their respective revenues in the last month
of a quarter, with these revenues frequently concentrated in the last two weeks
of a quarter. In addition, neither company operates with a large order backlog
because their software products are typically shipped shortly after orders are
received, which makes product revenues from licenses in any quarter
substantially dependent on orders booked and shipped throughout that quarter.
Accordingly, revenues for any given quarter are difficult to predict. IA has in
the past experienced and the combined company will continue to experience weaker
demand for its DecisionSuite software products during the summer months. Product
revenues are also difficult to forecast because the market for the combined
company's products is rapidly evolving, and the sales cycles for the two
companies, which may last from three to six months in the case of IQ and from
six to twelve months or more in the case of IA, vary substantially from customer
to customer. The combined company's expense level and plans for expansion,
including its plan to significantly increase its sales and marketing and
research and development efforts, will be based in significant part on the
combined company's expectations of future revenues and are relatively fixed in
the short-term. Consequently, if revenue levels are below expectations,
operating results are likely to be adversely and disproportionately affected. In
addition, the
 
                                       17
<PAGE>   31
 
combined company expects that sales derived through indirect channels, which are
more difficult to forecast and generally have lower gross margins than direct
sales, will increase as a percentage of total revenues.
 
     Based upon all of the factors described above, both IA and IQ believe that
their respective quarterly revenues, expenses and operating results are likely
to vary significantly in the future, that period-to-period comparisons of their
respective operating results are not necessarily meaningful and that, in any
event, such comparisons should not be relied upon as indications of the future
performance of the combined company. Accordingly, the combined company has
limited ability to forecast future revenues, and it is likely that in some
future quarter the combined company's operating results will be below the
expectations of public market analysts and investors. In the event that
operating results are below expectations, or in the event that adverse
conditions prevail or are perceived to prevail generally or with respect to the
combined company's business, the price of IA Common Stock would be materially
adversely affected.
 
LENGTHY SALES AND IMPLEMENTATION CYCLES
 
     The licensing of IA and IQ's respective products by their respective
customers typically involves a significant commitment of capital and other
resources, and is therefore subject to delays frequently associated with
customers' internal procedures to approve large capital expenditures and to test
and accept new technologies that affect key operations. For these and other
reasons, the sales cycle associated with the licensing of IA's products is
typically six to twelve months and for IQ's products is typically three to six
months. Both companies' sales cycles are subject to a number of significant
risks that are beyond such company's control, including customers' budgetary
constraints and internal acceptance reviews. Because of the lengthy sales cycle
and the large size of customers' orders, if revenues forecasted from a specific
customer for a particular quarter are not realized in that quarter, the combined
company's operating results for that quarter could be materially adversely
affected. In addition, the time required to deploy the combined company's
products can vary significantly with the needs of each customer and the
complexity of a customer's data processing needs. Accordingly, deployment of the
combined company's products may extend for several months and may involve a
pilot implementation, successful completion of which is typically a prerequisite
for full-scale deployment. In situations involving a pilot implementation of
products, revenue recognition is deferred until execution of a final license and
the other prerequisites for revenue recognition have been fulfilled. IA has
experienced difficulty implementing their products in the past due to the
complexity of customer requirements. IA generally relies upon internal resources
to implement its products. There can be no assurance that the combined company
will not experience delays in the implementation of orders in the future or that
third parties will be able to successfully install the combined company's
products. Any delays in the implementation of the combined company products
could have a material adverse effect on the combined company's business,
operating results and financial condition. In addition, any significant delay in
the implementation of the combined company products could cause a customer to
reject the combined company's software, which could impair the combined
company's reputation and have a material adverse effect on the combined
company's business, operating results and financial condition.
 
REVENUE RECOGNITION
 
     License agreements executed during any quarter may not meet the combined
company's revenue recognition criteria; as a result, the combined company may
meet or exceed its forecast of aggregate contracting activity, but not meet its
forecast for license revenues. In addition, Statement of Position ("SOP") 97-2,
"Software Revenue Recognition" was issued in October 1997 and addresses software
revenue recognition matters primarily from a conceptual level and does not
include specific implementation guidance. The SOP supersedes SOP 91-1 and is
effective for transactions entered into for fiscal years beginning after
December 15, 1997. Based on their interpretation of SOP 97-2, each of IA and IQ
believes it is currently in compliance with the final standard. However, further
implementation guidelines are currently being formulated. Once issued, such
implementation guidance could lead to unanticipated changes in the combined
company's current revenue accounting practices.
 
                                       18
<PAGE>   32
 
COMPETITION
 
     The markets in which IA and IQ compete, and the market in which the
combined company will compete, are competitive, highly fragmented and
characterized by rapidly changing technology and evolving standards. IA's
current and prospective competitors offer a variety of planning and analysis
software solutions and generally fall within three categories: (i) vendors of
desktop OLAP software such as Cognos and Business Objects; (ii) vendors of
multidimensional OLAP software such as Oracle (Express), Arbor Software, Seagate
(Holos) and SAS; and (iii) vendors of OLAP/relational database software such as
MicroStrategy and Platinum Technology (Prodea). IQ generally faces competition
from Actuate, Business Objects, Cognos, and Seagate (Crystal Reports). Each of
IA and IQ have experienced, and the combined company expects to continue to
experience, increased competition from current and potential competitors, many
of whom have significantly greater financial, technical, marketing and other
resources than the combined company. Such competitors may be able to respond
more quickly to new or emerging technologies and changes in customer
requirements or devote greater resources to the development, promotion and sales
of their products than the combined company. Also, certain current and potential
competitors, including companies such as Microsoft, IBM, Sybase and Informix,
may have greater name recognition or more extensive customer bases that could be
leveraged. These companies could integrate competing OLAP/relational database
software with other widely accepted products resulting in a loss of market share
for the combined company. The combined company expects additional competition as
other established and emerging companies enter into the OLAP and business
intelligence software markets and new products and technologies are introduced.
Increased competition could result in price reductions, fewer customer orders,
reduced gross margins, longer sales cycles and loss of market share, any of
which would materially adversely affect the combined company's business,
operating results and financial condition.
 
     Current and potential competitors may make strategic acquisitions or
establish cooperative relationships among themselves or with third parties,
thereby increasing their ability to address the needs of the combined company's
customers and prospective customers. The combined company's current or future
indirect channel partners may establish cooperative relationships with current
or potential competitors of the combined company, thereby limiting the combined
company's ability to sell its products through particular distribution channels.
Accordingly, it is possible that new competitors or alliances among current and
new competitors may emerge and rapidly gain significant market share. Such
competition could materially adversely affect the combined company's ability to
obtain new licenses, and maintenance and support renewals for existing licenses,
on terms favorable to the combined company. Further, competitive pressures may
require the combined company to reduce the price of the combined company
products, which would materially adversely affect the combined company's
business, operating results and financial condition. There can be no assurance
that the combined company will be able to compete successfully against current
and future competitors, and the failure to do so would have a material adverse
effect upon the combined company's business, operating results and financial
condition.
 
DEPENDENCE ON GROWTH OF MARKET FOR OLAP APPLICATIONS AND ACCEPTANCE OF THE WEB
 
     Although demand for the combined company products has grown in recent
years, the markets for OLAP and business intelligence software applications is
still emerging and there can be no assurance that it will continue to grow or
that, even if the market does grow, businesses will adopt the combined company's
products. Because a significant portion of the combined company's revenues are
derived from existing customer upgrades, the failure of such upgrades to occur
due to the lack of continued adoption of OLAP applications by its installed
customer base, would have a material adverse effect on the combined company's
business, operating results and financial condition. IA has spent, and the
combined company intends to continue spending, considerable resources educating
potential customers about the combined company products and its functions and
on-line analytical processing generally. However, there can be no assurance that
such expenditures will enable the combined company products to achieve any
additional degree of market acceptance, and if the market for the combined
company products fails to grow or grows more slowly than the combined company
currently anticipates, the combined company's business, operating results and
financial condition would be materially adversely affected. Historically, the
software industry has experienced significant periodic downturns, often in
connection with, or in anticipation of, declines in general economic
 
                                       19
<PAGE>   33
 
conditions during which management information systems budgets often decrease.
As a result, the combined company's business, operating results and financial
condition may in the future reflect substantial fluctuations from period to
period as a consequence of patterns and general economic conditions in the
software industry.
 
     In addition, the success of the combined company may be dependent on the
acceptance of the use of the World Wide Web as a means to disseminate
information. IA has had limited large-scale deployment of its products for use
on the Web. If customers determine that the combined company's products are not
scalable or are otherwise inadequate for Web-based use, or do not provide
adequate security for the dissemination of information over the Web, or if for
any other reason customers fail to accept the combined company's products for
use on the Web, the combined company's business, operating results and financial
condition could be materially adversely affected.
 
LIMITED LARGE-SCALE DEPLOYMENT
 
     IA believes that DecisionSuite can accommodate terabytes of data and
thousands of active users; however, IA has had only a limited number of
customers who have deployed DecisionSuite in such environments. If the combined
company's customers cannot successfully implement large-scale deployments or
determine for any other reason that the combined company's products cannot
accommodate large-scale enterprise applications, or that such products are not
required or appropriate for such widespread use, the combined company's
reputation and competitive advantage will be materially adversely affected,
which would, in turn, have a material adverse affect on the combined company's
business, operating results and financial condition.
 
RAPID TECHNOLOGICAL CHANGE AND NEW PRODUCTS
 
     The markets for IA and IQ's products are characterized by rapid
technological change, frequent new product introductions and enhancements,
uncertain product life cycles, changing customer demands and evolving industry
standards. The introduction of products embodying new technologies and the
emergence of new industry standards can render existing products obsolete and
unmarketable. IA has focused its efforts on products that run on UNIX operating
systems and has not developed a product that runs on Windows NT or any other
operating system. As more of the combined company's customers adopt Windows NT
for their businesses, the combined company will need to develop a Windows NT
version of the combined company products. The development of a Windows NT
product would require a substantial investment of resources by the combined
company, and there is no assurance that such a product could be introduced on a
timely or cost effective basis or at all. The future success of the combined
company will depend in large part on its ability to support popular operating
systems and databases, and on its ability to maintain and improve its proposed
product line and to develop new products on a timely basis that achieve market
acceptance, maintain technological competitiveness and meet an expanding range
of customer requirements. As a result of the complexities inherent in the
combined company's software development, major new products and product
enhancements can require long development and testing periods. In addition,
customers may delay their purchasing decisions in anticipation of the general
availability of new or enhanced versions of the combined company's products. As
a result, significant delays in the general availability of such new releases or
significant problems in the installation or implementation of such new releases
could have a material adverse effect on the combined company's business,
operating results and financial condition. There can be no assurance that the
combined company will be successful in developing and marketing, on a timely and
cost effective basis, product enhancements or new products that respond to
technological change, evolving industry standards or customer requirements, that
the combined company will not experience difficulties that could delay or
prevent the successful development, introduction or marketing of these
enhancements or that the combined company's new products and product
enhancements will achieve market acceptance.
 
PRODUCT AND CUSTOMER CONCENTRATION
 
     Substantially all of IA's revenues have been attributable to the
DecisionSuite line of products and related services and substantially all of
IQ's revenues have been attributed to the IQ suite of business intelligence
products and related services. Such products and services are expected to
account for substantially all of the
 
                                       20
<PAGE>   34
 
combined company's revenues for the foreseeable future. The combined company's
future operating results will depend upon continued market acceptance of the
DecisionSuite and the IQ products and enhancements to these products.
Consequently, a decline in the demand for, or market acceptance of, the combined
company products as a result of competition, technological change or other
factors, would have a material adverse effect on the combined company's
business, operating results and financial condition.
 
     A relatively small number of customers have accounted for a significant
percentage of IA's revenues. In fiscal 1996, MasterCard International
Incorporated accounted for 13.6% of total revenues for IA. In fiscal 1997, Tandy
Corporation accounted for 10.3% of total revenues for IA. While no single
customer accounted for more than 10% of total revenues for either IA or IQ in
fiscal 1998, the combined company expects that it will continue to be dependent
upon a limited number of new and existing customers for a significant portion of
its revenues in future periods. Such customers are expected to vary from period
to period. As a result, the failure by the combined company to successfully sell
its products or services to one or more targeted new or existing customers in
any particular period, or the deferral or cancellation of orders by one or more
of these customers, could have a material adverse effect on the combined
company's business, operating results and financial condition. The loss of a
major customer, or any reduction in orders by such customer, including
reductions due to market or competitive conditions, would have a material
adverse effect on the combined company's business, operating results and
financial condition.
 
DEPENDENCE ON SERVICE REVENUES
 
     Each of IA and IQ licenses software and provides related services, which
consist of maintenance, support, training, consulting and implementation. Total
license revenues and service revenues have increased from year to year. Service
revenues represented 52.4%, 44.7% and 46.6% of total revenues for IA for fiscal
1996, 1997 and 1998, respectively and represented 28.7%, 30.4% and 38.0% of
total revenues for IQ for fiscal 1996, 1997 and 1998, respectively. Each of IA
and IQ anticipates that service revenues for the combined company will continue
to represent a significant percentage of the combined company's total revenues.
To a large degree, the level of service revenues is dependent upon the ongoing
sales of professional services and the acceptance of maintenance contracts by IA
and IQ's respective growing installed customer bases. If service revenues are
less than anticipated, the combined company's operating results could be
materially adversely affected. The combined company's ability to increase its
service revenues will depend in large part on its ability to increase the scale
of its services organization, including its ability to successfully recruit and
train a sufficient number of qualified service representatives. There can be no
assurance that the combined company will be able to successfully expand its
service organization. In addition, there can be no assurance that the combined
company will be successful in implementing its strategy or that its products
will achieve market acceptance, the failure of which could have a material
adverse effect on its business, operating results and financial condition.
 
EXPANSION OF INDIRECT CHANNELS
 
     The combined company intends to expand IA's and IQ's relationships with
strategic partners and to increase the proportion of each company's customers
licensed through these indirect channels. IA's indirect channels have accounted
for less than 10% and IQ's indirect channels have accounted for approximately
30% of total revenues to date. There can be no assurance that the combined
company will continue to be represented by any of its indirect channels. Each of
IA and IQ is currently investing, and the combined company intends to
increasingly invest, significant resources to grow this channel, which could
adversely affect the combined company's operating results if the combined
company's efforts do not generate significant license revenues. There can be no
assurance that the combined company will be able to attract strategic partners
that will be able to market the combined company's products effectively and will
be qualified to provide timely and cost-effective customer support and service.
The failure to recruit strategic partners could adversely affect the combined
company's results of operations. The combined company's ability to achieve
revenue growth in the future will depend in large part on its success in
maintaining and establishing additional relationships with strategic partners.
In addition, if it is successful in selling products through this channel, the
combined company's gross margins will be negatively affected due to the lower
unit prices that the combined company expects to receive when selling through
indirect channels.
 
                                       21
<PAGE>   35
 
RISKS ASSOCIATED WITH INTERNATIONAL SALES AND OPERATIONS
 
     During fiscal 1996, 1997 and 1998, IA derived 10.7%, 9.5% and 9.7% of its
total revenues, respectively, and IQ derived 24.7%, 33.1% and 31.6% of its total
revenues, respectively, from sales outside the United States. The combined
company anticipates that for the foreseeable future a significant portion of its
revenues will be derived from sources outside the United States. The combined
company intends to continue to expand IA's and IQ's sales and support operations
outside the United States and to enter additional international markets. In
order to successfully expand international sales, the combined company must
establish additional foreign operations, expand IA's and IQ's international
channel management and support organizations, hire additional personnel, recruit
additional international resellers and increase the productivity of existing
international resellers. To the extent that the combined company is unable to do
so in a timely and cost-effective manner, the combined company's growth, if any,
in international sales will be limited, and the combined company's business,
operating results and financial condition could be materially adversely
affected. The combined company also expects to commit additional resources to
customizing its products for selected international markets and developing
international channel sales and support organizations. In addition, even if
international operations are successfully expanded and the combined company's
products are successfully customized, there can be no assurance that the
combined company will be able to maintain or increase international market
demand for its products.
 
     The combined company's international operations are generally subject to a
number of risks, including costs of customizing products for foreign countries,
protectionist laws and business practices favoring local competition, dependence
on local vendors, compliance with multiple, conflicting and changing government
laws and regulations, longer sales and payment cycles, import and export
restrictions and tariffs, difficulties in staffing and managing foreign
operations, greater difficulty or delay in accounts receivable collection,
foreign currency exchange rate fluctuations, multiple and conflicting tax laws
and regulations and political and economic instability. To date, a majority of
the combined company's revenues and costs have been denominated in U.S. dollars.
However, the combined company believes that an increasing portion of the
combined company's revenues and costs will be denominated in foreign currencies.
Although the combined company may from time to time undertake foreign exchange
hedging transactions to cover a portion of its foreign currency transaction
exposure, the combined company does not currently attempt to cover any foreign
currency exposure.
 
MANAGEMENT OF GROWTH; NEED FOR ADDITIONAL QUALIFIED PERSONNEL
 
     IA has recently experienced a period of significant revenue growth and an
expansion in the number of its employees, the scope of its operating and
financial systems and geographic area of its operations. From January 31, 1995
to July 31, 1998, IA increased its headcount from 75 to 254. Further significant
increases in the number of employees for the combined company are anticipated in
fiscal 1999. For example, the combined company currently plans to expand its
sales and marketing services and research and development efforts by, among
other things, significantly increasing the number of employees dedicated to
those areas. This growth has resulted, and will continue to result, in new and
increased responsibilities for management personnel and may place a strain upon
the combined company's management, operating financial systems and resources.
The combined company expects that planned expansion of international operations
will lead to increased financial and administrative demands, such as increased
operational complexity associated with expanded facilities, administrative
burdens associated with managing an increasing number of relationships with
foreign partners and expanded treasury functions to manage foreign currency
risks. The combined company's future operating results will also depend on its
ability to further develop indirect channels to penetrate different and broader
markets and expand its support organization to accommodate growth in the
combined company's installed base. The failure of the combined company to manage
its expansion effectively could have a material adverse effect on the combined
company's business, operating results and financial condition.
 
DEPENDENCE ON KEY PERSONNEL
 
     The combined company's success will depend to a significant degree upon the
efforts of certain key management, technical support, sales, marketing, customer
support and research and development personnel.
 
                                       22
<PAGE>   36
 
The loss of key personnel could adversely affect the combined company. The
combined company's future success will depend in large part upon its continuing
ability to attract and retain highly skilled managerial, sales, marketing,
customer support and research and development personnel. Like other software
companies, the combined company will face intense competition for such
personnel, and each of IA and IQ has at times experienced and continues to
experience difficulty in recruiting qualified personnel. In addition, the
complexity of both IA's and IQ's products make it especially difficult to find,
attract and retain such personnel. There can be no assurance that the combined
company will be successful in attracting, assimilating or retaining qualified
personnel in the future. The loss of the services of one or more of the combined
company's key individuals, or the failure to attract and retain additional
qualified personnel, could have a material and adverse effect on the combined
company's business, operating results and financial condition.
 
LIMITED PROTECTION OF PROPRIETARY TECHNOLOGY; RISKS OF INFRINGEMENT; USE OF
LICENSED TECHNOLOGY
 
     Each of IA and IQ rely primarily on a combination of copyright and
trademark laws, trade secrets, confidentiality procedures and contractual
provisions to protect its respective proprietary technology. For example, IA
licenses its software pursuant to signed license agreements, which impose
certain restrictions on licensees' ability to utilize the software. In addition,
each company seeks to avoid disclosure of its trade secrets, including requiring
those persons with access to such proprietary information to execute
confidentiality agreements with such company and restricting access to that
company's source code. Each company further seeks to protect its software,
documentation and other written materials under trade secret and copyright laws,
which afford only limited protection.
 
     Despite the combined company's efforts to protect its proprietary rights,
unauthorized parties may attempt to copy aspects of the combined company's
products or to obtain and use information that the combined company regards as
proprietary. Policing unauthorized use of each company's products is difficult,
and while each company is unable to determine the extent to which piracy of its
respective software products exists, software piracy can be expected to be a
persistent problem for the combined company. In addition, the laws of many
countries do not protect the combined company's proprietary rights to as great
an extent as do the laws of the United States. There can be no assurance that
the combined company's means of protecting its proprietary rights will be
adequate or that the combined company's competitors will not independently
develop similar technology.
 
     To date, neither IA nor IQ has been notified that its respective products
infringe the proprietary rights of third parties, but there can be no assurance
that third parties will not claim infringement by the combined company with
respect to current or future products. Both IA and IQ expect that data warehouse
and data mart software product developers will increasingly be subject to
infringement claims as the number of products and competitors in the combined
company's industry segment grows and the functionality of products in different
industry segments overlaps. Any such claims, with or without merit, could be
time-consuming, result in costly litigation, cause product shipment delays or
require the combined company to enter into royalty or licensing agreements. Such
royalty or licensing agreements, if required, may not be available on terms
acceptable to the combined company or at all, which could have a material
adverse effect upon the combined company's business, operating results and
financial condition.
 
IQ CLASS ACTION LITIGATION
 
     On October 23, 1997, a complaint was served on IQ and certain of its
executive officers on behalf of purchasers of IQ Common Stock between May 8,
1996 and February 3, 1997 alleging violations of Sections 10(b) and 20(a) of the
Securities Exchange Act of 1934 ("Claim"). The Claim alleges that IQ failed to
disclose the risks and liabilities assumed by IQ in connection with the
transition of its sales force from an inside telesales model to an outside
field-based model. IQ believes that the claim is without merit and both IA and
IQ intend for the combined company to vigorously defend the action. Regardless
of the merits of the Claim, however, defending against such Claim could be time
consuming resulting in costly litigation and diverting the combined company's
management's attention and resources. In the event IQ or the combined company is
unsuccessful in defending against the Claim, the combined company's business,
operating results and financial condition would be materially and adversely
affected.

RISK OF SOFTWARE DEFECTS
 
     Software products as internally complex as those offered by IA and IQ
frequently contain errors or defects, especially when first introduced or when
new versions or enhancements are released. Despite product testing, each of IA
and IQ has in the past released versions of its products with defects and has
discovered software errors in those products after their introduction. Although
neither IA nor IQ has experienced material adverse effects resulting from any
such defects and errors to date, there can be no assurance that, despite testing
by the combined company and by current and potential customers, defects and
errors will not be found in new versions or enhancements after commencement of
commercial shipments resulting in loss of revenues or delay in market
acceptance, which could have a material adverse effect upon the combined
company's business, operating results and financial condition. See "-- Year 2000
Compliance" and "-- Product Liability."
 
YEAR 2000 COMPLIANCE
 
     Many currently installed computer systems and software products are coded
to accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish 21st century dates from
20th century dates. As a result, in less than two years, computer systems and
software used by many companies may need to be upgraded to comply with such
"Year 2000" requirements. Although IA and IQ believe that their products are
Year 2000 compliant, each company believes that the purchasing patterns of
customers and potential customers may be affected by Year 2000 issues as
companies expend a significant portion of their limited information technology
resources to correct or patch their current software systems for Year 2000
compliance. These expenditures may result in reduced funds available to purchase
software products such as those offered by the combined company, which could
result in a material adverse effect on the combined company's business,
operating results and financial condition. IA uses outside vendors to supply its
most significant data processing software. These vendors have indicated their
products are Year 2000 compliant or will be Year 2000 compliant in the near
future. IA does not currently have any information concerning the Year 2000
compliance status of its or IQ's key suppliers and customers. In the event that
any such key suppliers or customers do not achieve Year 2000 compliance in a
timely manner, or at all, the combined company's business or operations could be
adversely affected.
 
PRODUCT LIABILITY
 
     Although IA's and IQ's license agreements with their respective customers
typically contain provisions designed to limit each company's exposure to
potential product liability claims, it is possible that such limitation of
liability provisions may not be effective as a result of existing or future laws
or unfavorable judicial decisions. Neither company has experienced any product
liability claims to date. However, the sale and support of the combined
company's products may entail the risks of such claims, which are likely to be
substantial in light of the use of the combined company's products in
business-critical applications. A product liability claim brought against the
combined company could have a material adverse effect on the combined company's
business, operating results and financial condition.
 
POSSIBLE VOLATILITY OF COMMON STOCK
 
     The market price of IA's Common Stock after the Merger is likely to be
highly volatile and may be significantly affected by factors such as actual or
anticipated fluctuations in the combined company's operating results,
announcements of technological innovations, new products or new contracts by the
combined company or its competitors, developments with respect to copyrights or
proprietary rights, conditions and trends in the software and other technology
industries, adoption of new accounting standards affecting the software
industry, changes in financial estimates by securities analysts, general market
conditions, unanticipated events or announcements and other factors. In
addition, the stock market has from time to time experienced significant price
and volume fluctuations that have particularly affected market prices for common
stocks of technology companies. In the past, following periods of volatility in
the market price of a particular company's securities, securities class action
litigation has often been brought against such combined company. Such litigation
is currently pending against IQ and there can be no assurance that additional
litigation will not occur in the future with respect to the combined company.
Such litigation could result in substantial costs and a
 
                                       24
<PAGE>   38
 
diversion of management's attention and resources, which could have a material
adverse effect upon the combined company's business, operating results and
financial condition. See "-- IQ Class Action Litigation."
 
CONTROL OF COMBINED COMPANY BY EXECUTIVE OFFICERS, DIRECTORS AND FIVE PERCENT
STOCKHOLDERS
 
     The executive officers, directors, five percent stockholders of the
combined company and their affiliates in the aggregate will beneficially own
approximately 39.4% of the outstanding IA Common Stock immediately following the
Merger. As a result, these stockholders are able to exercise significant control
over matters requiring stockholder approval, including the election of directors
and approval of significant corporate transactions. Such concentration of
ownership may have the effect of delaying or preventing a change in control of
the combined company.
 
EFFECT OF CERTAIN CHARTER PROVISIONS; ANTITAKEOVER EFFECTS OF CERTIFICATE OF
INCORPORATION, BYLAWS AND DELAWARE LAW
 
     IA's Certificate of Incorporation and Bylaws contain certain provisions
that may have the effect of discouraging, delaying or preventing a change in
control of the combined company or unsolicited acquisition proposals that a
stockholder might consider favorable, including provisions authorizing the
issuance of "blank check" Preferred Stock, requiring the consent of holders of
at least 80% of the combined company's capital stock to amend the Certificate of
Incorporation or Bylaws, eliminating the ability of stockholders to act by
written consent or call a special meeting of stockholders and providing for a
Board of Directors with staggered, three-year terms. In addition, certain
provisions of Delaware law and IA's 1997 Equity Incentive Plan may also have the
effect of discouraging, delaying or preventing a change in control of the
combined company or unsolicited acquisition proposals. The antitakeover effect
of these provisions may also have an adverse effect on the public trading price
of the IA Common Stock. See "Description of IA Capital Stock" and "Comparison of
Rights of IA Stockholders and IQ Stockholders."

     An IA stockholder or an IQ stockholder who has executed and returned a
proxy may revoke such proxy at any time before it is voted at the IA Special
Meeting or the IQ Special Meeting, as the case may be, by executing and
returning a proxy bearing a later date, by filing written notice of such

IA STOCKHOLDER VOTE REQUIRED
 
     Approval of the issuance of shares of IA Common Stock in connection with
the Merger pursuant to the IA Merger Proposal requires the affirmative vote of a
majority of those shares present in person or represented by proxy and entitled
to vote at the IA Special Meeting.
 
     On the IA Record Date, IA directors, executive officers and their

     Votes cast by proxy or in person at the IA Special Meeting will be
tabulated by the election inspectors appointed for the meeting and will
determine whether or not a quorum is present. The election inspectors will treat
abstentions as shares that are present and entitled to vote for purposes of
determining the presence of a quorum but as unvoted for purposes of determining
the approval of the IA Merger Proposal. Since the required vote of IA
stockholders is based upon the number of outstanding shares of IA Common Stock,
such abstentions and broker nonvotes will have the effect of a vote against the
IA Merger Proposal.
 
IQ STOCKHOLDER VOTE REQUIRED
 
     Approval of the IQ Merger Proposal requires the affirmative vote of the
holders of 66 2/3% of the outstanding shares of IQ Common Stock. On the IQ

proxy, will constitute a quorum for the transaction of business at the IQ
Special Meeting or any adjournment thereof.
 
     Votes cast by proxy or in person at the IQ Special Meeting will be
tabulated by the election inspectors appointed for the meeting and will
determine whether or not a quorum is present. The election inspectors will treat
abstentions and broker non-votes as shares that are present and entitled to vote
for purposes of determining the presence of a quorum but as unvoted for purposes
of determining the approval of the IQ Merger Proposal. Since the required vote
of IQ stockholders is based upon the number of outstanding shares of IQ Common

Statement of which it is a part. If the Merger is not completed for certain
reasons, such expenses will be paid as described under the caption "The Merger
Agreement and Related Transactions -- Termination; Termination Fees and
Expenses." In addition to solicitation by mail, the directors, officers and
employees of IA and IQ and stockholders of IA and IQ, respectively, may solicit

Special Meeting and the shares of IA Common Stock to be issued pursuant to the
Merger will be listed on the Nasdaq National Market as of the Effective Time.
Holders of IA Common Stock are not entitled to appraisal rights under Section

                      THE MERGER AND RELATED TRANSACTIONS
 
GENERAL
 
     The Plan of Merger provides for the merger of Merger Sub, a newly formed,
wholly owned subsidiary of IA, with and into IQ, with IQ to be the surviving
corporation of the Merger and a wholly owned subsidiary of IA. The discussion of
the Merger in this Joint Proxy Statement/Prospectus and the description of the
principal terms of the Plan of Merger are subject to and qualified in their
entirety by reference to the Plan of Merger which is attached hereto as Appendix
A.
 
MATERIAL CONTACTS AND BOARD DELIBERATIONS
 
     Beginning in January 1998, representatives of IA and representatives of IQ
had conversations from time to time principally concerning the possibility of a
business partnering arrangement involving the two companies. These conversations
were exploratory in nature and did not progress beyond the preliminary stage.
 
     On May 4, 1998, Larry J. Ford, the Chief Executive Officer of IA, met with
Charles R. Chitty, the Chief Executive Officer of IQ, to formally discuss a
business combination which led to a decision to seriously pursue a business
combination.
 
     On May 7, 1998, IA engaged BancAmerica Robertson Stephens to act as its
financial advisor in connection with a possible transaction.
 
     On May 19, 1998, representatives and advisors of IA and representatives and
advisors of IQ conducted preliminary due diligence discussions, explored
strategic benefits of a merger and held preliminary discussions relating to
valuation and structure of a proposed transaction.
 
     From May 19 through June 5, 1998, the parties continued to negotiate the
terms, valuation and structure of a possible transaction.
 
     On June 1, 1998, the IQ Board authorized the retention of First Albany to
act as its financial advisor in connection with a possible transaction.
 
                                       28
<PAGE>   42
 
     From June 6, 1998 through June 9, 1998, representatives and advisors to IA
conducted their due diligence investigation of IQ and representatives and
advisors to IQ conducted their due diligence investigation of IA.
 
     From June 23, 1998 through June 25, 1998, IA and IQ and their respective
advisors held a series of meetings and discussions regarding the Plan of Merger,
the Stock Option Agreement and related documents, and the financial, legal and
accounting due diligence investigation of the respective companies. During this
period, representatives and advisors of IA and IQ also held several meetings to
discuss the valuation of the Merger.
 
     On June 26, 1998, there was a telephonic meeting of the IQ Board to approve
the Plan of Merger and related transactions. First Albany informed the IQ Board
of its oral opinion (subsequently confirmed in writing) that as of such date the
Exchange Ratio was fair from a financial point of view to IQ, and responded to
various questions raised by members of the IQ Board regarding such opinion. The
IQ Board reviewed a draft of the Plan of Merger, the Stock Option Agreement and
related documents and a partner from Miller & Martin responded to questions
regarding such documents from the IQ Board. After considering the terms of the
proposed transaction and the opinion of First Albany, the IQ Board determined
that the Merger was fair to IQ stockholders and that the proposed Merger was in
the best interests of IQ and its stockholders. The IQ Board then unanimously
approved the Plan of Merger and exhibits thereto, including the Stock Option
Agreement, and the Merger and unanimously resolved to recommend that the
stockholders of IQ vote for the IQ Merger Proposal.
 
     On June 28, 1998, there was a telephonic meeting of the IA Board to approve
the Plan of Merger and related transactions. BancAmerica Robertson Stephens
informed the IA Board of its oral opinion (subsequently confirmed in writing)
that as of such date the Exchange Ratio was fair from a financial point of view
to IA, and responded to various questions raised by members of the IA Board
regarding such opinion. The IA Board reviewed a draft of the Plan of Merger, the
Stock Option Agreement and related documents and a partner from Gunderson
Dettmer responded to questions regarding such documents from the IA Board. After
considering the terms of the proposed transaction and the opinion of BancAmerica
Robertson Stephens, the IA Board determined that the Merger was fair to IA
stockholders and that the proposed Merger was in the best interests of IA and
its stockholders. The IA Board then unanimously approved the Plan of Merger and
exhibits thereto, including the Stock Option Agreement, and the Merger and
unanimously resolved to recommend that the IA stockholders vote for the IA
Merger Proposal.
 
     During the afternoon and evening of June 28, 1998 and the morning and
afternoon of June 29, 1998, following approval of the Plan of Merger and related
matters by the IA Board and the IQ Board, IA and IQ finalized, executed and
delivered the Plan of Merger, the Stock Option Agreement and related documents.
 
     A joint press release announcing the execution of the Plan of Merger and
the terms of the Merger was issued by IA and IQ on the evening of June 29, 1998.
 
     On July 24, 1998, the Plan of Merger was amended to effect certain
technical changes.
 
REASONS FOR THE MERGER
 
     IA's Reasons for the Merger. In order to expand its product offerings, IA
has examined on occasion various potential alliances, including the proposed
combination with IQ. During its discussions with IQ, IA recognized the
complementary nature of IQ's products, marketing, distribution channels and
technology. In reaching its decision to approve the Plan of Merger and the
Merger, the IA Board consulted with (i) its legal counsel regarding the legal
terms of the transaction and the IA Board's obligations in its consideration of
the proposed transaction, (ii) its financial advisors regarding the financial
aspects of the proposed transaction and the BancAmerica Robertson Stephens
Opinion that the Exchange Ratio pursuant to the Plan of Merger was fair from a
financial point of view to IA and (iii) the management of IA.
 
                                       29
<PAGE>   43
 
     The IA Board concluded that the Merger represented a unique strategic fit
between two companies with similar business strategies and complementary
software offerings and that the Merger was in the best interests of IA and its
stockholders. In reaching this conclusion, the IA Board considered the following
information and factors:
 
     - The combination of IA with IQ will create a combined company with
       significantly greater resources, and provide the opportunity to market a
       more complete product offering and greater sales and marketing
       capabilities than those of IA alone, and may enable the combined company
       to compete more effectively with competitors having greater resources and
       broader product offerings than IA.
 
     - The combination of IQ's software with IA's software allows IA to enhance
       its competitive position as a leader in relational on-line analytical
       processing software by allowing it to offer more robust products and
       business intelligence products.
 
     - The Merger will provide IA with the opportunity to broaden and diversify
       its product offerings with complementary software tools that it currently
       does not offer, which may reduce the risk of dependence on individual
       products.
 
     - IA believes that the management team of the combined company will have
       greater depth and experience than that of IA alone.
 
     - The financial and other terms and conditions of the Plan of Merger and
       the related agreements, including the fact that (i) the Merger is
       expected to be accounted for as a pooling of interests in accordance with
       Accounting Principles Board Opinion No. 16 and that no goodwill is
       expected to be created as a result of the Merger and (ii) the Merger is
       expected to be treated as a tax-free reorganization to IA and its
       stockholders.
 
     - IA believes the combination will give it greater access to product
       development resources.
 
     - A larger combined customer base and complementary distribution channels
       will provide leverage for expanded sales and marketing opportunities for
       the combined company.
 
     - The potential for achieving long-term economies of scale, particularly in
       the future growth of IA's worldwide operations, that would not have been
       as readily achievable by IA alone.
 
     - Information concerning the historical financial performance, business
       operations, financial condition and prospects of IQ, including IQ's
       periodic reports filed with the SEC and publicly available financial
       information regarding IQ such as third-party analysts' reports, analysts'
       projections and analysts' comments and historical stock price, volatility
       and volume data.
 
     - The oral and written presentations of its financial advisor, BancAmerica
       Robertson Stephens, including the opinion of BancAmerica Robertson
       Stephens that the Exchange Ratio pursuant to the Plan of Merger was fair
       from a financial point of view to IA.
 
     In the course of its deliberations, the IA Board reviewed and considered
the terms and conditions of the Plan of Merger and the presentations by IA's
executive officers. The IA Board also considered, among other matters, (i)
information concerning IA's and IQ's respective businesses, prospects, financial
performance and condition, operations, technology, management and competitive
position, (ii) the historical financial condition, results of operations and
businesses of IA and IQ, (iii) current financial market conditions and
historical market prices, volatility and trading information with respect to IA
Common Stock and IQ Common Stock, (iv) the relationship between the market value
of IA Common Stock to be issued in exchange for each share of IQ Common Stock
and IA's and IQ's per share reported earnings, earnings before interest and
taxes and certain other measures, (v) a comparison of selected recent
acquisition and merger transactions involving high-technology companies, (vi)
the belief that the terms of the Plan of Merger, including the parties'
respective representations, warranties and covenants, and the conditions to
their respective obligations, are reasonable, (vii) the ability of IA to devote
management time and energy to the integration and assimilation of IQ's business
and organization should the Merger be consummated, (viii) the fact that the
Merger is expected to be accounted for as a pooling of interests and that no
goodwill is expected to be created on the
 
                                       30
<PAGE>   44
 
financial statements of IA as a result thereof, (ix) the impact of the Merger on
IA's and IQ's customers, including the potential loss of revenue that might
result due to uncertainty among customers caused by the Merger, and (x) reports
from management, accounting advisors and legal advisors as to the results of
their due diligence investigation of IQ.
 
     The IA Board also considered a number of potentially negative factors in
its deliberations concerning the Merger, including, but not limited to, (i) the
adverse effects on the operating results of the combined company due to the
expenses expected to be incurred, primarily in the quarter in which the Merger
is consummated, including costs of integrating the businesses of IQ and IA and
transaction expenses arising from the Merger, (ii) the risk that benefits sought
to be achieved in the Merger will not be realized, which may have a material
adverse effect on the combined company's business, operating results and
financial condition, (iii) the risk that the operations of IA and IQ will not be
effectively integrated or that potential synergies expected to result from the
consolidation of the operations of the companies will not occur, and (iv) the
other risks described under "Risk Factors."
 
     The foregoing discussion of the information and factors considered by the
IA Board is not intended to be exhaustive but is believed to include all
material factors considered by the IA Board. In view of the wide variety of
factors considered by the IA Board, the IA Board did not find it practicable to
quantify or otherwise assign relative weights to the specific factors considered
in approving the Plan of Merger and the Merger. However, after taking into
account all of the factors set forth above, the IA Board unanimously determined
that the Plan of Merger and the Merger were in the best interests of IA and its
stockholders and that IA should enter into the Plan of Merger and complete the
Merger. ACCORDINGLY, THE IA BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS OF IA
VOTE FOR APPROVAL AND ADOPTION OF THE IA MERGER PROPOSAL.
 
     IQ's Reasons for the Merger. In reaching its decision to approve the Plan
of Merger and the Merger, the IQ Board consulted with (i) its legal counsel
regarding the legal terms of the transaction and the IQ Board's obligations in
its consideration of the proposed transaction, (ii) its financial advisors
regarding the financial aspects of the proposed transaction and the fairness of
the Exchange Ratio to IQ's stockholders from a financial point of view and (iii)
the management of IQ.
 
     The IQ Board concluded that the Merger represents a unique strategic fit
between two companies with similar business strategies and complementary
software offerings and that the Merger was in the best interests of IQ and its
stockholders. In reaching this conclusion, the IQ Board considered the following
information and factors:
 
          - The potential for the combined company to provide a broader range of
            products, product features and solutions as a result of the Merger,
            thereby enhancing the combined company's competitive strength and
            increasing its ability to satisfy the requirements of existing and
            new customers. IQ and IA operate in a rapidly growing and changing
            marketplace, providing comprehensive analysis software that enables
            large companies to improve their financial performance by maximizing
            the value of information. The Merger would improve IQ's competitive
            position as a leader in enterprise reporting software applications
            by allowing it to satisfy customer needs through an increasingly
            comprehensive set of product offerings, including the combined
            strength of IQ's application software and IA's technology.
 
          - The potential benefits from a combination of the management
            resources of IQ and IA, including the experience, knowledge and
            established customer relationships of senior personnel at both
            companies.
 
          - The potential for achieving long-term economies of scale,
            particularly in the future growth of IQ's worldwide operations, that
            would not have been readily achievable by either company separately.
 
          - The ability of IQ to develop products more quickly and to attract
            and retain critical and scarce engineering talent as a result of
            having access to both companies' financial, development, personnel
            and other resources.

          - The potential for increased revenues by selling into IA's installed
            customer base and through its sales force.
 
          - The financial and other significant terms and conditions of the Plan
            of Merger and the related agreements, including the fact that (i)
            the Merger is expected to be accounted for as a pooling of interests
            in accordance with Accounting Principles Board Opinion No. 16 and
            that no goodwill is expected to be created as a result of the Merger
            and (ii) the Merger is expected to be treated as a tax-free
            reorganization to IQ and its stockholders.
 
          - Information concerning the historical financial performance,
            business operations, financial condition and prospects of IA,
            including IA's periodic reports filed with the SEC and publicly
            available financial information regarding IA such as third-party
            analysts' reports, analysts' projections and analysts' comments and
            historical stock price, volatility and volume data.
 
          - The presentations of its financial advisor, First Albany, including
            the opinion of First Albany that, as of June 26, 1998, the Exchange
            Ratio was fair from a financial point of view to the holders of IQ
            Common Stock.
 
     The IQ Board also considered potentially negative factors relating to the
Merger, including (i) the risk that the benefits sought in the Merger would not
be fully achieved, (ii) the risk that the Merger would not be consummated and
the effect of the public announcement of the Merger on IQ's sales and operating
results, (iii) the impact of the Merger on key customer relationships, (iv) the
charges expected to be incurred in connection with the Merger, including costs
of integrating the business and transaction expenses arising from the Merger,
(v) the difficulty of and risks associated with integrating the combined company
and managing operations in distant geographic locations, (vi) the risks of IQ
suffering employee attrition or of failing to attract key personnel due to
uncertainties associated with the pending Merger and (vii) all of the other
factors listed above under "Risk Factors." The IQ Board concluded that these
factors were outweighed by the potential benefits to be gained by the Merger.
 
     The foregoing discussion of the information and factors considered by the
IQ Board is not intended to be exhaustive but is believed to include all
material factors considered by the IQ Board. In view of the wide variety of
information and factors, both positive and negative, considered by the IQ Board,
the IQ Board did not find it practical to, and did not, quantify or otherwise
assign relative or specific weights to the foregoing factors considered. After
taking into consideration all of the factors set forth above, the IQ Board
unanimously determined that the Plan of Merger and the Merger were in the best
interests of IQ and its stockholders and that IQ should enter into the Plan of
Merger and complete the Merger. ACCORDINGLY, THE IQ BOARD UNANIMOUSLY RECOMMENDS
THAT STOCKHOLDERS OF IQ VOTE FOR APPROVAL AND ADOPTION OF THE IQ MERGER
PROPOSAL.
 
OPINION OF IA FINANCIAL ADVISOR
 
     On May 7, 1998, IA and BancAmerica Robertson Stephens executed an
engagement letter (the "BancAmerica Robertson Stephens Engagement Letter")
pursuant to which BancAmerica Robertson Stephens was engaged to render an
opinion as to the fairness of the Exchange Ratio, from a financial point of
view, to IA.
 
     On June 28, 1998, at a meeting of the IA Board held to evaluate the
proposed Merger, BancAmerica Robertson Stephens delivered to the IA Board its
oral opinion, which was subsequently confirmed as a written opinion dated June
28, 1998, that as of June 28, 1998 and based on the matters described therein,
the Exchange Ratio was fair, from a financial point of view, to IA. No
limitations were imposed by the IA Board on BancAmerica Robertson Stephens with
respect to the investigations made or procedures followed by it in furnishing
its opinion. The Exchange Ratio was determined through negotiations between the
managements of IA and IQ. Although BancAmerica Robertson Stephens did assist the
management of IA in those negotiations, it was not asked by, and did not
recommend to, IA that any specific exchange ratio constituted the appropriate
exchange ratio for the Merger. BancAmerica Robertson Stephens also assisted IA's
management in the negotiations leading to an agreement on principal structural
terms of the transaction.

BancAmerica Robertson Stephens expresses no opinion as to the tax consequences
of the Merger, and BancAmerica Robertson Stephens' opinion as to the fairness of
the Exchange Ratio does not take into account the particular tax status or
position of any stockholder of IA. In furnishing its opinion, BancAmerica
Robertson Stephens was not engaged as an agent or fiduciary of IA's stockholders
or any other third party.
 
     THE FULL TEXT OF THE BANCAMERICA ROBERTSON STEPHENS OPINION, WHICH SETS
FORTH, AMONG OTHER THINGS, ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS
ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS APPENDIX B AND IS INCORPORATED
HEREIN BY REFERENCE. STOCKHOLDERS OF IA ARE URGED TO READ THE BANCAMERICA
ROBERTSON STEPHENS OPINION IN ITS ENTIRETY. THE BANCAMERICA ROBERTSON STEPHENS
OPINION WAS PREPARED FOR THE BENEFIT AND USE OF THE IA BOARD IN ITS
CONSIDERATION OF THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION TO
STOCKHOLDERS OF IA AS TO HOW THEY SHOULD VOTE AT THE IA SPECIAL MEETING IN
CONNECTION WITH THE MERGER. THE BANCAMERICA ROBERTSON STEPHENS OPINION DOES NOT
ADDRESS THE RELATIVE MERITS OF THE MERGER AND ANY OTHER TRANSACTIONS OR BUSINESS
STRATEGIES DISCUSSED BY THE IA BOARD AS ALTERNATIVES TO THE PLAN OF MERGER OR
THE UNDERLYING BUSINESS DECISION OF THE IA BOARD TO PROCEED WITH THE MERGER
PROCESS. THE SUMMARY OF THE BANCAMERICA ROBERTSON STEPHENS OPINION SET FORTH IN
THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE FULL TEXT OF THE BANCAMERICA ROBERTSON STEPHENS OPINION.
 
     In connection with the preparation of the BancAmerica Robertson Stephens
Opinion, BancAmerica Robertson Stephens, among other things, (i) reviewed
financial information with respect to IA and IQ furnished to it by IA and IQ,
including certain internal financial analyses and forecasts prepared by the
managements of IA and IQ, respectively; (ii) reviewed certain publicly available
information concerning IA and IQ, including their respective stock price and
trading histories; (iii) held discussions with the managements of IA and IQ
concerning the businesses, past and current business operations, financial
condition and future prospects of both companies, independently and combined;
(iv) reviewed the financial terms and conditions of the June 26, 1998 draft of
the Plan of Merger; (v) reviewed the exchange-ratio implied by historical stock
prices of the two companies; (vi) reviewed the valuations of publicly traded
companies that were deemed comparable to IQ; (vii) prepared discounted cash flow
analyses of IQ; (viii) compared the financial terms of the Merger set forth in
the June 26, 1998 draft of the Plan of Merger with other transactions that were
deemed relevant; (ix) prepared pro forma merger analyses for the Merger; and (x)
made such other studies and inquiries and reviewed such other data, as it deemed
relevant.
 
     In conducting its review and arriving at its opinion, BancAmerica Robertson
Stephens assumed and relied upon, without independent verification, the
accuracy, completeness and fairness of the information furnished to or otherwise
reviewed by or discussed with it for purposes of rendering its opinion.
BancAmerica Robertson Stephens did not obtain or make or assume responsibility
for obtaining or making any independent evaluation or appraisal of the
properties or assets of IA or IQ, nor has BancAmerica Robertson Stephens been
furnished with any such evaluations or appraisals. BancAmerica Robertson
Stephens did not have access to any non-public information regarding the
stockholder class action litigation against IQ and assumed, with the consent of
IA, that the pending and any future litigation against IQ would not have a
material adverse effect on IQ's business, financial condition, and operating
results. BancAmerica Robertson Stephens received estimates of IA's projected
financial performance that were prepared by the management of IA. BancAmerica
Robertson Stephens also reviewed and discussed with the management of IA
publicly-available projections of analysts regarding the financial performance
of IQ and estimates of IQ's projected financial performance that were prepared
by the management of IQ. With the consent of the IA Board, this information was
used by BancAmerica Robertson Stephens in comparable company, precedent
transaction, exchange ratio and implied premium analysis, discounted cash flow,
relative contribution and pro forma earnings analyses summarized below. With
respect to financial and operating forecasts of IA and IQ provided to
BancAmerica Robertson Stephens by each company, BancAmerica Robertson Stephens
assumed that such forecasts were reasonably prepared in good faith on the basis
of reasonable assumptions, reflecting the best available estimates and judgments
of the respective managements of IA and IQ. BancAmerica Robertson Stephens
assumed that the Merger would be accounted for as a "pooling of interests" under
generally accepted accounting principles. The BancAmerica Robertson Stephens
Opinion is based on the closing trading prices of IA Common Stock and IQ Common
Stock, as of June 26, 1998 and on market, economic and other conditions as they
existed or were disclosed to BancAmerica Robertson Stephens and could be
evaluated as of the date of the BancAmerica Robertson Stephens Opinion and made
available to BancAmerica Robertson Stephens on such date. In
 
                                       33
<PAGE>   47
 
rendering the BancAmerica Robertson Stephens Opinion, BancAmerica Robertson
Stephens assumed that the Merger would be consummated substantially upon the
terms described in the Plan of Merger without any waiver of any material terms
or conditions by any party thereto. Although developments following the date of
the BancAmerica Robertson Stephens Opinion may affect the opinion, BancAmerica
Robertson Stephens assumed no obligation to update, revise or reaffirm its
opinion. BancAmerica Robertson Stephens expressed no opinion as to the value of
any employee agreements or arrangements entered into in connection with the
Merger.
 
     The following is a summary of the material financial analysis performed by
BancAmerica Robertson Stephens in connection with rendering the BancAmerica
Robertson Stephens Opinion.
 
     Comparable Company Analysis. Using publicly available information,
BancAmerica Robertson Stephens analyzed, among other things, the market values
plus net debt (the "Total Capitalization") and trading multiples of IQ and
selected publicly traded companies that have similar business and operating
profiles, including: IA, Brio Technology, Business Objects, Microstrategy,
Cognos, Adept Technology, Boole & Babbage, Information Management Association,
Landmark Systems, Macneal-Schwendler Corp., Progress Software Corp., Project
Software & Development, Rainbow Technologies, SPSS, Stan Electronics and USCS
International, (collectively, the "Comparable Companies"). From among the
Comparable Companies, BancAmerica Robertson Stephens then selected from the
following companies: IA, Cognos, Business Objects and Brio Technology (the
"Selected Companies"). Multiples compared by BancAmerica Robertson Stephens
included Total Capitalization to estimated revenues for calendar 1998 and 1999
and market capitalization to estimated net income for calendar 1998 and 1999.
All multiples were based on closing stock prices as of June 26, 1998. Applying a
range of multiples for the Selected Companies of estimated calendar years 1998
and 1999, revenues of 1.3x to 3.5x, and 1.0x to 3.0x, respectively, to
corresponding financial data for IQ resulted in an equity reference range for IQ
of approximately $9.93 to $22.86 per share. Applying a range of estimated
calendar years 1998 and 1999 price/earnings multiples for the Selected Companies
of 14.0x to 20.0x and 12.0x to 18.0x, respectively, to corresponding financial
data for IQ resulted in an equity reference range for IQ of approximately $9.20
to $13.80 per share. These equity reference ranges compared to the equity value
implied by the Exchange Ratio of approximately $13.50 per share based on the
closing stock price of IA Common Stock on June 26, 1998.
 
     Precedent Transaction Analysis. Using publicly available information,
BancAmerica Robertson Stephens analyzed the consideration offered plus net debt
assumed (the "Total Consideration") and implied transaction value multiples paid
or proposed to be paid in selected merger or acquisition transactions in the
software industry (the "Comparable Transactions"). BancAmerica Robertson
Stephens compared, among other things, the Total Consideration in such
transaction as a multiple of latest 12 months revenues. Applying a range of
multiples for the Comparable Transactions of latest 12 months revenues of 2.0x
to 4.0x to corresponding financial data for IQ resulted in an equity reference
range for IQ of approximately $13.88 to $24.30 per share, as compared to the
equity value implied by the Exchange Ratio of approximately $13.50 per share
based on the closing stock price of IA Common Stock on June 26, 1998. All
multiples for the Comparable Transactions were based on public information
available at the time of the announcement of such transactions, without taking
into account differing market and other conditions during the period in which
the Comparable Transactions occurred.
 
     No company, transaction or business used in Comparable Company Analysis or
Precedent Transaction Analysis as a comparison is identical to IA, IQ or the
combined company. Accordingly, an analysis of the results of the foregoing is
not entirely mathematical; rather it involves complex considerations and
judgments concerning differences in financial and operating characteristics and
other factors that could affect the acquisition, public trading and other values
of the Comparable Companies, Comparable Transactions or the business segment,
company or transactions to which they are being compared.
 
     Exchange Ratio and Implied Premium Analysis. BancAmerica Robertson Stephens
reviewed and analyzed the historical ratio of the daily per share market closing
prices of IA Common Stock and IQ Common Stock over several time periods, each
ending on June 26, 1998. BancAmerica Robertson Stephens noted that the Exchange
Ratio represents a premium of 56.4% to the average price ratio since IA's
initial public offering, a premium of 56.8% to the average price ratio for the
trailing 90 trading days, a premium of 52.2% to the average price ratio for
 
                                       34
<PAGE>   48
 
the trailing 60 trading days, a premium of 45.2% to the average price ratio for
the trailing 30 trading days prior to June 26, 1998, and a premium of 22.8% to
the average price ratio on June 26, 1998.
 
     Relative Contribution Analysis. BancAmerica Robertson Stephens analyzed the
respective contributions of IA and IQ to the estimated revenues, gross profit,
EBIT, and net income of the combined company for fiscal years 1999 and 2000.
This analysis indicated that in fiscal year 1999, IA would contribute
approximately 62.1% of revenue, approximately 60.8% of gross profit,
approximately 34.4% of EBIT and approximately 36.6% of net income and IQ would
contribute approximately 37.9% of revenue, approximately 39.2% of gross profit,
approximately 65.6% of EBIT and approximately 63.4% of net income, of the
combined company, and (ii) in fiscal year 2000, IA would contribute
approximately 68.0% of revenue, approximately 66.8% of gross profit,
approximately 61.8% of EBIT and approximately 58.9% of net income, and IQ would
contribute approximately 32.0% of revenue, approximately 33.2% of gross profit,
approximately 38.2% of EBIT and approximately 41.1% of net income, of the
combined company. Based on market capitalizations of IA and IQ as of June 26,
1998, stockholders of IA and IQ would own approximately 67.5% and 32.5%,
respectively, of the combined company, upon consummation of the Merger.
 
     Discounted Cash Flow Analysis. BancAmerica Robertson Stephens performed a
discounted cash flow analysis of the unlevered (before interest expense)
after-tax cash flows of IQ using a range of earnings estimates for IQ for the
fiscal years 1998 through 2003. BancAmerica Robertson Stephens first discounted
the projected, unlevered after-tax cash flows through January 31, 2003 using a
range of discount rates from 18% to 22%. IQ unlevered after-tax cash-flows were
calculated as the after-tax operating earnings of IQ adjusted to add back
non-cash expenses and deduct uses of cash not reflected in the income statement.
BancAmerica Robertson Stephens then added to the present value of the cash flows
the terminal value of IQ in the fiscal year ended January 31, 2003, discounted
back at the same discount rate. The terminal value was computed by multiplying
the projected EBIT for IQ in fiscal 2003 by terminal multiples ranging from
10.0x to 14.0x. The range of terminal multiples selected reflect BancAmerica
Robertson Stephens's judgment as to an appropriate range of multiples at the end
of the referenced period. The discounted cash flow valuation resulted in an
equity reference range of approximately $11.43 to $15.80 per share, as compared
to the equity value implied by the Exchange Ratio of approximately $13.50 per
share based on the closing price of IA Common Stock on June 26, 1998.
 
     Pro Forma Earnings Analysis. BancAmerica Robertson Stephens analyzed
certain pro forma effects resulting from the Merger, including, among other
things, the impact of the Merger on the projected earnings per share ("EPS") of
the combined company for the fiscal years 1998 and 1999. Without taking into
account certain cost savings that the combined company may realize in its
operations, the results of the pro forma earnings analysis suggested that the
Merger could be accretive to the combined company's EPS in the fiscal years 1998
and 1999. The actual results achieved by the combined company may vary from
projected results and the variations may be material.
 
     Other Factors and Comparative Analyses. In rendering its opinion,
BancAmerica Robertson Stephens considered certain other factors and conducted
certain other comparative analyses, including, among other things, a review of
(i) the history of trading prices and volume for each of IA Common Stock, for
the period from December 17, 1997 to June 26, 1998, and IQ Common Stock for the
period June 26, 1997 to June 26, 1998, and (ii) selected published analysts'
reports on each of IA and IQ, including analysts' estimates as to the earnings
growth potential of IA and IQ.
 
     While the foregoing summary describes certain analyses and factors that
BancAmerica Robertson Stephens deemed material in its presentation to the IA
Board, it is not a comprehensive description of all analyses and factors
considered by BancAmerica Robertson Stephens. The preparation of a fairness
opinion is a complex process that involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances and, therefore, such an opinion is
not readily susceptible to summary description. BancAmerica Robertson Stephens
believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all analyses and factors, would create an incomplete view of the
evaluation process underlying the BancAmerica Robertson Stephens Opinion.
Several analytical methodologies were employed and no one method of analysis
should be regarded as critical to the overall conclusion reached by
 
                                       35
<PAGE>   49
 
BancAmerica Robertson Stephens. Each analytical technique has inherent strengths
and weaknesses, and the nature of the available information may further affect
the value of particular techniques. The conclusions reached by BancAmerica
Robertson Stephens are based on all analyses and factors taken as a whole and
also on application of BancAmerica Robertson Stephens' own experience and
judgment. Such conclusions may involve significant elements of subjective
judgment and qualitative analysis. BancAmerica Robertson Stephens therefore
gives no opinion as to the value or merit standing alone of any one or more
parts of the analysis it performed. In performing its analyses, BancAmerica
Robertson Stephens considered general economic, market and financial conditions
and other matters, many of which are beyond the control of IA and IQ. The
analyses performed by BancAmerica Robertson Stephens are not necessarily
indicative of actual values or future results, which may be significantly more
or less favorable than those suggested by such analyses. Accordingly, analyses
relating to the value of a business do not purport to be appraisals or to
reflect the prices at which the business actually may be purchased. Furthermore,
no opinion is being expressed as to the prices at which shares of IA Common
Stock may be traded at any future time.
 
     The BancAmerica Robertson Stephens Engagement Letter provides that, for its
services, BancAmerica Robertson Stephens is entitled to receive, contingent upon
consummation of the Merger, a transaction fee based upon the Aggregate
Transaction Value (as defined in the BancAmerica Robertson Stephens Engagement
Letter). IA has also agreed to reimburse BancAmerica Robertson Stephens for
certain of its out-of-pocket expenses and to indemnify and hold harmless
BancAmerica Robertson Stephens and its affiliates and any person, director,
employee or agent of BancAmerica Robertson Stephens or any of its affiliates, or
any person controlling BancAmerica Robertson Stephens or its affiliates for
certain losses, claims, damages, expenses and liabilities relating to or arising
out of services provided by BancAmerica Robertson Stephens as financial advisor
to IA. The terms of the fee arrangement with BancAmerica Robertson Stephens,
which IA and BancAmerica Robertson Stephens believe are customary in
transactions of this nature, were negotiated at arm's length between IA and
BancAmerica Robertson Stephens, and the IA Board was aware of such fee
arrangements, including the fact that a significant portion of the fees payable
to BancAmerica Robertson Stephens is contingent upon completion of the Merger.
In addition, BancAmerica Robertson Stephens served as lead underwriter on IA's
initial public offering in December 1997 for which it received certain
underwriting commissions.
 
     BancAmerica Robertson Stephens was retained based on BancAmerica Robertson
Stephens' experience as a financial advisor in connection with mergers and
acquisitions and in securities valuations generally, as well as BancAmerica
Robertson Stephens' investment banking relationship and familiarity with IA.
 
     BancAmerica Robertson Stephens is a nationally recognized investment
banking firm. As part of its investment banking business, BancAmerica Robertson
Stephens is frequently engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of securities, private placements and
other purposes. BancAmerica Robertson Stephens may actively trade the equity
securities of IA and IQ for its own account and for the account of its customers
and, accordingly, may at any time hold a long or short position in such
securities.
 
OPINION OF IQ'S FINANCIAL ADVISOR
 
     Pursuant to an engagement letter dated June 3, 1998 (the "First Albany
Engagement Letter"), IQ engaged First Albany to act as its exclusive financial
advisor in connection with evaluating an offer from IA to acquire IQ on the
terms and conditions set forth in the Plan of Merger. First Albany is a
nationally recognized firm and, as part of its investment banking activities, is
regularly engaged in the valuation of businesses and their securities in
connection with merger transactions and other types of acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. IQ selected
First Albany as its financial advisor on the basis of its experience and
expertise in transactions similar to the Merger and its reputation as an
investment banker in transactions involving high-technology companies.
 
     At the June 26, 1998 meeting of the IQ Board, First Albany delivered its
oral opinion, confirmed in writing as of June 26, 1998 that the consideration to
be received by IQ's stockholders in the Merger, when
 
                                       36
<PAGE>   50
 
taken as a whole, is fair to IQ's stockholders from a financial point of view.
The amount of such consideration was determined pursuant to negotiations between
IQ and IA and not pursuant to recommendations of First Albany. No limitations
were imposed by IQ on First Albany with respect to the investigations made or
procedures followed in rendering its opinion.
 
     THE FULL TEXT OF THE FIRST ALBANY OPINION TO THE IQ BOARD, WHICH SETS FORTH
THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS OF REVIEW BY FIRST
ALBANY, IS ATTACHED HERETO AS APPENDIX C, AND IS INCORPORATED HEREIN BY
REFERENCE AND SHOULD BE READ CAREFULLY AND IN ITS ENTIRETY IN CONNECTION WITH
THIS PROXY STATEMENT/PROSPECTUS. THE FOLLOWING SUMMARY OF THE FIRST ALBANY
OPINION IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE
OPINION. THE FIRST ALBANY OPINION IS ADDRESSED TO THE IQ BOARD ONLY AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY IQ STOCKHOLDERS AS TO HOW SUCH STOCKHOLDER
SHOULD VOTE AT THE IQ SPECIAL MEETING. IN FURNISHING ITS OPINION, FIRST ALBANY
DID NOT ADMIT THAT IT IS AN EXPERT WITHIN THE MEANING OF THE TERM "EXPERT" AS
USED IN THE SECURITIES ACT AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER,
OR THAT ITS OPINION IS A REPORT OR VALUATION WITHIN THE MEANING OF SECTION 11 OF
THE SECURITIES ACT, AND STATEMENTS TO SUCH EFFECT ARE INCLUDED IN THE FIRST
ALBANY OPINION. FIRST ALBANY HAS NOT ASSUMED RESPONSIBILITY FOR PERFORMING THE
LEVEL OF DILIGENCE OR INDEPENDENT VERIFICATION THAT WOULD BE REQUIRED FOR IT TO
RENDER A REPORT OR VALUATION FOR PURPOSES OF THE SECURITIES ACT. ACCORDINGLY,
FIRST ALBANY BELIEVES THAT THE FIRST ALBANY OPINION SHOULD NOT BE ACCORDED THE
DEGREE OF RELIANCE PLACED ON SUCH REPORTS AND VALUATIONS.
 
     First Albany has informed IQ that in arriving at its opinion, First Albany,
among other matters: (i) reviewed certain publicly available financial and other
data with respect to IQ and IA, including the consolidated financial statements
for the years ended January 31, 1998 and 1997, financial statements for the
quarter ended April 30, 1998 for IQ and IA, and certain other relevant financial
and operating data relating to IQ and IA made available to First Albany from
published sources and from the internal records of IQ and IA; (ii) reviewed the
financial terms and conditions of the Plan of the Merger; (iii) reviewed certain
publicly available information concerning the trading of, and the trading market
for, the IQ Common Stock and IA Common Stock; (iv) compared IQ and IA from a
financial point of view with certain other companies in the business
intelligence software industry which it deemed to be relevant; (v) considered
the financial terms, to the extent publicly available, of selected recent
business combinations of business intelligence software companies and the larger
software sector which it deemed to be comparable; (vi) reviewed and discussed
with representatives of the management of IQ and IA certain information of a
business and financial nature regarding IQ and IA furnished to First Albany by
such companies, including financial forecasts and related assumptions of IQ and
IA; and (vii) performed such other analyses and examinations that it deemed
appropriate.
 
     In preparing the First Albany Opinion, First Albany did not assume any
obligation independently to verify the financial and other information reviewed
by it for purposes of its opinion and relied on its accuracy and completeness in
all material respects. With respect to the financial forecasts for IQ and IA
provided to First Albany by their respective managements, First Albany assumed
for purposes of its opinion that the forecasts (including the assumptions
regarding anticipated operational efficiencies) were reasonably prepared on
bases reflecting the best available estimates and judgments by their respective
managements at the time of preparation as to the future financial performance of
the combined company following the Merger, and that they provided First Albany a
reasonable basis upon which First Albany could form its opinion. First Albany
assumed that there had been no material changes in IQ's or IA's assets,
financial condition, results of operations, business or prospects since the
respective dates of their last financial statements made available to First
Albany. First Albany relied on advice of counsel and independent accountants to
IQ as to all legal and financial reporting matters with respect to IQ, the
Merger and the Plan of Merger, including the legal status and financial
reporting of litigation involving IQ. First Albany also assumed that the Merger
will be consummated (i) in a manner that complies in all respects with the
applicable provisions of the Securities Act, the Exchange Act and all other
applicable federal and state statutes, rules and regulations, and (ii) in
accordance with the terms described in the Plan of Merger, without any further
amendments thereto, and without waiver by IQ of any of the conditions to its
obligations thereunder. In addition, First Albany did not make an independent
evaluation, appraisal or physical inspection of any of the assets or liabilities
(contingent or otherwise) of IQ or IA, and was not furnished with any such
appraisals. First Albany assumed, based on advice by IQ, that the Merger will be
recorded as a "pooling of interests" under generally accepted accounting
 
                                       37

principles. Finally, the First Albany Opinion is based on economic, financial
and securities market and other conditions as in effect on, and the information
made available to it as of June 26, 1998.
 
     Set forth below is a brief summary of material analyses presented by First
Albany to the IQ Board on June 26, 1998 and in connection with the First Albany
Opinion.
 
     Comparable Public Company Analysis. Using public and other available
information, First Albany analyzed and compared selected data and ratios for IQ
to the corresponding data and ratios of certain other companies in the software
industry whose securities are publicly traded and which First Albany believes
have operating, market valuation and trading valuations similar to what might be
expected of IQ. These companies included Business Objects S.A., Comshare, Inc.,
Gentia Software plc ADR, Prism Solutions, and Red Brick Systems (collectively,
the "Comparable Companies"). Primary multiples, data and ratios compared by
First Albany included the cash normalized-revenue multiple, which was derived by
subtracting each company's cash balances from its market valuation and dividing
the result by latest twelve month revenues ("LTM"), estimated forward twelve
month ("FTM") revenues and market value as a multiple of estimated 1998 and 1999
calendar year earnings per share ("EPS"). The multiples for IQ were based on the
implied equity value of IQ given the Exchange Ratio and IA's closing stock price
as of June 23, 1998. All multiples for the Comparable Companies were based on
closing stock prices as of June 23, 1998 and, with respect to estimates of
future performance for the Comparable Companies, on analysts reports and other
publicly available information. First Albany relied on revenue multiples since
most of the Comparable Companies do not have positive EPS estimates, which
render a price-to-earnings multiple comparison meaningless. First Albany
observed that IQ is valued at 1.9x LTM revenues verses 1.3x LTM revenues for the
Comparable Companies and 1.6x FTM revenues versus 1.1x FTM revenues for the
Comparable Companies. Applying the average multiple for the Comparable Companies
of LTM revenues of 1.3x to corresponding financial data for IQ resulted in an
equity reference of $9.24 per share. Applying the average multiple for the
Comparable Companies of FTM revenues of 1.1x to corresponding financial data for
IQ resulted in an equity reference of $9.28 per share. These equity references
compared to the equity value implied by the Exchange Ratio of approximately
$13.50 per share based on the closing price of IA Common Stock on June 26, 1998.
 
     Precedent Transaction Analysis. First Albany examined the consideration
paid, to the extent publicly available, in a number of acquisitions of
publicly-traded technology companies. The transactions reviewed for this
analysis included seventeen acquisitions completed or announced between
September 5, 1997 and March 17, 1998. First Albany compared, among other things,
the percentage premiums represented by the consideration paid in such
transactions over the market price for IQ Common Stock at one day prior to
announcement of the transaction. This analysis yielded median premiums of
approximately 28% for such time period for the seventeen transactions involving
companies most comparable to IQ and IA. First Albany observed that the premium
offered for this transaction was 25% or 3% below the median of acquisitions
involving other publicly-traded technology companies over this six month period.
 
     Exchange Ratio Analysis. First Albany reviewed the ratios of the prices of
IQ Common Stock to IA Common Stock over the six month period ended June 19, 1998
and computed the premium over these ratios represented by the Exchange Ratio. On
average, the closing price of IQ Common Stock has been 1.24x that of IA Common
Stock for the six month period ended June 19, 1998. First Albany observed that
the Exchange Ratio, which is 1.96 shares of IA Common Stock for each share of IQ
Common Stock, represents a premium of approximately 60% over the average
exchange ratio.
 
     Discounted Cash Flow Analysis. First Albany performed discounted cash flow
analyses for IQ based on a range of earnings estimates for IQ for the fiscal
years 2000 through 2003. The analyses aggregated (a) the present value of the
projected after tax cash flow (defined as after tax operating earnings of IQ
adjusted to add back non-cash expenses and deduct uses of cash not reflected in
the income statement), through 2003 and (b) the present value of a range of
terminal values for the year 2003.
 
     The terminal multiple for IQ was determined by its current LTM
price-to-earnings multiple of 15x. Such analysis indicated a net present value
of approximately $50.3 million or approximately $10.70 dollars per share of IQ
Common Stock, compared to the $63 million, or $13.50 per share, implied equity
value of IQ given the Exchange Ratio and IA's closing stock price as of June 26,
1998.

     While the foregoing summary describes all analyses and examinations that
First Albany deems material to its opinion, it is not a comprehensive
description of all analyses and examinations actually performed by First Albany.
The preparation of a fairness opinion necessarily is not susceptible to partial
analysis or summary description. First Albany believes that such analysis and
the summary set forth above must be considered as a whole and that selecting
portions of its analyses and of the factors considered, without considering all
such analysis and factors, would create an incomplete view of the analyses set
forth in its presentation to the IQ Board. In addition, First Albany may have
given various analyses more or less weight than other analyses, and may have
deemed various assumptions more or less probable than other assumptions, so that
the ranges of valuations resulting from any particular analysis should not be
taken to be First Albany's view of the actual value of IQ, IA or the combined
company.
 
     In performing its analyses, First Albany made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of IQ or IA. The analyses
performed by First Albany are not necessarily indicative of actual values or
actual future results, which may be significantly more or less favorable than
suggested by such analyses. Such analyses were prepared solely as part of First
Albany's analysis of the fairness of the Merger to IQ's stockholders from a
financial point of view and were provided to the IQ Board in connection with the
delivery of the First Albany Opinion. The analyses do not purport to be
appraisals or to reflect the prices at which a company might actually be sold or
the prices at which any securities may trade at the present time or at any time
in the future. First Albany used in certain of its analyses various projections
of future results prepared by the managements of IQ and IA. The projections are
based on numerous variables and assumptions which are inherently unpredictable
and must be considered not certain of occurrence as projected. Accordingly,
actual results could vary significantly from those set forth in such
projections.
 
     As described above, the First Albany Opinion and presentation to the IQ
Board were among the many factors taken into consideration by the IQ Board in
making its determination to approve, and to recommend that its stockholders
approve, the Merger.
 
     Pursuant to the First Albany Engagement Letter dated June 3, 1998, IQ paid
First Albany a retainer fee of $25,000. Upon the distribution to the
stockholders of IQ of this Joint Proxy Statement/Prospectus, IQ will be
obligated to pay First Albany a fee of $175,000. Upon consummation of the
Merger, IQ will become obligated to pay First Albany a fee of $225,000. IQ has
also agreed to reimburse First Albany for its reasonable out-of-pocket expenses
up to $25,000. Pursuant to a separate Indemnification and Contribution
Agreement, IQ has agreed to indemnify First Albany, its affiliates, and their
respective partners, directors, officers, agents, consultants, employees and
controlling persons against certain liabilities, including liabilities under the
federal securities laws.
 
     In the ordinary course of its business, First Albany makes a market in IQ
Common Stock and IA Common Stock. In the course of its market making and other
trading activities, First Albany may from time to time have long or short
positions in and buy, and sell equity securities of, IQ or IA. Other than acting
as IQ's financial advisor in connection with, and having participated in certain
of the negotiations leading to, the Plan of Merger, First Albany has not
provided any investment banking services to IQ. First Albany acted as one of the
three co-managing underwriters of IA's initial public offering of IA Common
Stock in December 1997.
 
CONVERSION OF IQ SHARES
 
     Upon consummation of the Merger, pursuant to the Plan of Merger, each
issued and outstanding share of IQ Common Stock (other than shares owned by IA
or by IQ or any subsidiary of IQ), will be converted into the right to receive
1.96 shares of IA Common Stock. Based upon the number of outstanding shares of
IA Common Stock and IQ Common Stock as of August 14, 1998, the stockholders of
IQ immediately prior to the consummation of the Merger will own approximately
36.4% (including shares issuable upon the exercise of outstanding options to
purchase shares of IA Common Stock and IQ Common Stock) of the outstanding
shares of IA Common Stock immediately following consummation of the Merger. If
any holder of shares of IQ Common Stock would be entitled to receive a number of
shares of IA Common Stock that includes a
 
                                       39
<PAGE>   53
 
fraction, then, in lieu of a fractional share, such holder will be entitled to
receive cash in an amount equal to such fractional share of IA Common Stock
multiplied by the average of the last reported sales price of IA Common Stock,
as reported on the Nasdaq National Market, on each of the ten trading days
immediately preceding the Closing Date. Each share of Merger Sub Common Stock
issued and outstanding immediately prior to the Effective Time will be converted
into one share of IQ Common Stock.
 
     As soon as reasonably practicable after the Effective Time, Norwest Bank
Minnesota, National Association (the "Exchange Agent") will mail transmittal
forms and exchange instructions to each holder of record of IQ Common Stock to
be used to surrender and exchange certificates formerly evidencing shares of IQ
Common Stock for certificates evidencing the shares of IA Common Stock to which
such holder has become entitled. After receipt of such transmittal forms, each
holder of certificates formerly representing IQ Common Stock will be able to
surrender such certificates to the Exchange Agent, and each such holder will
receive in exchange therefor certificates evidencing the number of whole shares
of IA Common Stock to which such holder is entitled and any cash which may be
payable in lieu of a fractional share of IA Common Stock.
 
     After the Effective Time, each certificate formerly representing IQ Common
Stock, until so surrendered and exchanged, shall be deemed, for all purposes, to
evidence only the right to receive the number of whole shares of the IA Common
Stock that the holder of such certificate is entitled to receive in the Merger
and any cash payment in lieu of a fractional share of the IA Common Stock. The
holder of such unexchanged certificate will not be entitled to receive any
dividends or other distributions payable by the combined company until the
certificate has been exchanged. Subject to applicable laws, following surrender
of such certificates, such dividends and distributions, together with any cash
payment in lieu of a fractional share of the IA Common Stock, will be paid
without interest. IQ STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL
THEY RECEIVE A TRANSMITTAL FORM.

addition, IQ shall notify IA promptly following the execution by IQ or any of
its subsidiaries of any agreement providing for the receipt of amounts in excess
of $500,000 or payment of amounts in excess of $50,000.
 
     IA has agreed to promptly notify IQ of any material event or occurrence
whether or not incurred in the ordinary course of business. Pursuant to the Plan
of Merger, each of IA and IQ has agreed to provide each other reasonable access
to their respective representatives, personnel, assets and facilities and to all
books, records, tax returns, work papers and other documents related to the
companies and copies of such.
 
     Pursuant to the Plan of Merger, IA and IQ each agree to use best efforts to
(i) take all appropriate action to consummate the transactions contemplated by
the Plan of Merger as promptly as practical, (ii) obtain any consents, licenses,
permits, waivers, approvals, authorizations or orders from Governmental Entities
(as defined in the Plan of Merger) or other third parties required in connection
with the transactions contemplated by the Plan of Merger and (iii) make all
necessary filings and submissions with respect to the transactions contemplated
by the Plan of Merger under federal, state and foreign securities laws,
antitrust laws and other applicable laws. IA and IQ also agree to use their best
efforts to obtain any governmental clearances or approvals under antitrust law
required for the closing of the Merger, including contesting and resisting
governmental action and having vacated, lifted, reversed or overturned any
decree, judgment, injunction or other order that would prohibit the Merger or
any transactions contemplated by the Plan of Merger. Notwithstanding the
foregoing, neither IA nor IQ is required to take any action that would
reasonably be expected to have a material adverse effect on IA or IQ.
 
     Pursuant to the Plan of Merger, IA and IQ have agreed to execute a Reseller
Agreement with respect to IQ's products. See "-- Reseller Agreement."
 
NO SOLICITATION
 
     The Plan of Merger provides that IQ will not, directly or indirectly,
through any officer, director, employee, financial advisor, representative,
subsidiary or agent of such party, (i) take any action to solicit, initiate or
encourage any inquiries or proposals that constitute, or could reasonably be
expected to lead to, a proposal or offer for a merger, consolidation, business
combination, sale of substantial assets, sale of shares of capital stock
(including without limitation by way of a tender offer) or similar transaction
involving IQ or any of its subsidiaries, other than the transactions
contemplated by the Plan of Merger (any of the foregoing inquiries or proposals
being referred to as an "Acquisition Proposal"), (ii) engage in negotiations or
discussions concerning, or provide any non-public information to any person or
entity relating to, any
 
                                       41
<PAGE>   55
 
Acquisition Proposal, or (iii) agree to or recommend any Acquisition Proposal;
provided, however, that nothing contained in the Plan of Merger shall prevent IQ
or the IQ Board, to the extent the IQ Board determines in good faith, based upon
and consistent with advice received in consultation with outside legal counsel,
that fiduciary duties to stockholders under applicable law so require, from (a)
furnishing non-public information to, or entering into discussions or
negotiations with, any person or entity in connection with an unsolicited bona
fide written Acquisition Proposal by such person or entity or recommending an
unsolicited bona fide written Acquisition Proposal to the stockholders of such
party, if and only to the extent that (1) the IQ Board believes in its good
faith reasonable judgment (based upon and consistent with advice received in
consultation with independent financial and legal advisors) that such
Acquisition Proposal is reasonably capable of being completed on the terms
proposed and, after taking into account the strategic benefits anticipated to be
derived from the Merger and the long-term prospects of IQ and IA as a combined
company, would, if consummated, result in a transaction more favorable over the
long term from a financial point of view than the transaction contemplated by
the Plan of Merger (any such more favorable Acquisition Proposal being referred
to as a "Superior Proposal") and the IQ Board determines in good faith after
consultation with, and based upon and consistent with advice received from,
outside legal counsel that such action is necessary for the IQ Board to comply
with its fiduciary duties to stockholders under applicable law and (2) prior to
furnishing such non-public information to, or entering into discussions or
negotiations with, such person or entity, the IQ Board of Directors receives
from such person or entity an executed confidentiality agreement with terms no
less favorable to such party than those contained in the agreement dated June
17, 1998 between IA and IQ, and provided such non-public information has been
previously delivered to the IA Board and IQ advises IA in writing of such
disclosure or negotiations, including the party to whom disclosed or with whom
discussions or negotiations will occur; or (b) complying with Rules 14d-9 and
14e-2 promulgated under the Exchange Act with regard to an Acquisition Proposal.
 
     IQ is required to promptly notify IA (orally and in writing) upon receipt
of any Acquisition Proposal or request for non-public information or access to
its properties, books or records in connection with an Acquisition Proposal.
 
INTERESTS OF CERTAIN PERSONS
 
     As of the IQ Record Date, directors and executive officers of IQ and their
affiliates beneficially owned an aggregate of 532,104 shares of IQ Common Stock
(excluding 74,750 shares of IQ Common Stock subject to unexercised stock
options). Based on the last reported sales price for IA Common Stock on August
19, 1998 of $6.625, the aggregate dollar value of the shares of IA Common Stock
to be received in the Merger by the executive officers and directors of IQ and
their affiliates (excluding shares subject to stock options) is approximately
$6.9 million.
 
     The directors and executive officers of IQ have agreed to vote all shares
of IQ Common Stock under their control in favor of the IQ Merger Proposal and
have executed voting agreements and granted irrevocable proxies to IA. See
"-- Voting Agreements."
 
     The Plan of Merger provides that Charles R. Chitty, the Chairman of the
Board, President and Chief Executive Officer of IQ shall become a member of the
IA Board following the Effective Time. In addition, Mr. Chitty will enter into a
three year employment and consulting agreement with IA, effective upon the
Effective Time, whereby Mr. Chitty will assume the role of IA's Senior Vice
President of Vertical Applications. See "-- Employment Agreement."
 
     Certain of the stock option agreements held by executive officers of IQ,
provide for the acceleration of existing vesting provisions in the event of a
change of control of IQ such as the Merger. As a result of such provisions,
options to purchase 45,000 additional shares of IQ Common Stock will vest on the
Effective Date. See "-- IQ Stock Option Plans."
 
     Pursuant to the Plan of Merger, IA has agreed that the surviving
corporation shall indemnify each person who was an officer or director of IQ
against certain liabilities. See "-- Director and Officer Indemnification."
 
                                       42
<PAGE>   56
 
     As a result of the foregoing transactions and agreements, certain of the
directors and executive officers of IQ have personal interests in the Merger and
Plan of Merger that are not identical to the interests of IQ stockholders.
 
VOTING AGREEMENTS
 
     In connection with the Plan of Merger, the IQ directors, executive officers
and their affiliates (the "Voting Agreement Stockholders") have executed Voting
and Irrevocable Proxy Agreements in favor of IA (the "Voting Agreements").
Pursuant to the Voting Agreements, the Voting Agreement Stockholders (who
beneficially own an aggregate of 532,104 outstanding shares of IQ Common Stock
representing approximately 11.4% of the outstanding shares of IQ Common Stock on
the IQ Record Date) have agreed that they will vote all shares of IQ Common
Stock under their control (i) in favor of approval of the Plan of Merger and the
Merger and any matter that could reasonably be expected to facilitate the
Merger, and (ii) against approval of any proposal made in opposition to, or
competition with, consummation of the Merger and against any merger,
consolidation, sale of assets, reorganization or recapitalization, with any
party other than IA and its affiliates and against any liquidation or winding up
of IQ. The Voting Agreement Stockholders have also agreed not to solicit or
encourage any offer from any party concerning the possible disposition of all or
any substantial portion of IQ's business, assets or capital stock and in the
event the IQ Board does not call a stockholder meeting to approve the Merger,
the Voting Agreement Stockholders have agreed to take all action necessary to
call a stockholder meeting to approve the Merger or to approve the Merger by
written consent. In order to effectuate the foregoing, the Voting Agreement
Stockholders have also appointed IA as their irrevocable proxy with respect to
the matters covered by the Voting Agreement. A copy of the form of Voting
Agreement included as an exhibit to the Plan of Merger contained in Appendix A
to this Joint Proxy Statement/Prospectus.
 
RESALE OF IA COMMON STOCK; AGREEMENTS WITH AFFILIATES
 
     The shares of IA Common Stock to be issued in the Merger have been
registered under the Securities Act and will be freely transferable, subject to
certain limitations on resale described in this Joint Proxy
Statement/Prospectus. As a condition to the obligations of the parties under the
Plan of Merger, IA and IQ have each received agreements from each person or
entity who may be deemed an affiliate (as defined in the Securities Act and the
rules and regulations thereunder) of IA or IQ, pursuant to which such persons
have agreed not to sell, transfer or otherwise dispose of shares of IQ Common
Stock or IA Common Stock for 30 days prior to the Effective Time and until such
time after the Effective Time as IA has publicly released a report including the
combined financial results of IA and IQ for a period of at least 30 days of
combined operations of IA and IQ. Furthermore, pursuant to such agreements, the
affiliates of IQ have agreed to refrain from the sale or transfer of any IA
Common Stock received in connection with the Merger, except in accordance with
the provisions of the Securities Act and the general rules and regulations
thereunder. Copies of the forms of agreements executed by affiliates of IA and
IQ are included as exhibits to the Plan of Merger contained in Appendix A to
this Joint Proxy Statement/Prospectus. See "Risk Factors -- Pooling of
Interests" and "-- Shares Eligible for Public Sale."
 
RELATED MATTERS AFTER THE MERGER
 
     At the Effective Time, (i) Merger Sub will be merged with and into IQ and
IQ will be the surviving corporation and a wholly-owned subsidiary of IA. The
Articles of Incorporation of Merger Sub, as in effect immediately prior to the
Effective Time, shall become the Articles of Incorporation of IQ at the
Effective Time. The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall become the Bylaws of IQ at the Effective Time.
 
IQ STOCK OPTION PLANS
 
     At the Effective Time, each outstanding option to purchase shares of IQ
Common Stock (an "IQ Stock Option"), whether vested or unvested, shall be deemed
to constitute an option to acquire, on the same terms and conditions as were
applicable under such IQ Stock Option, the same number of shares of IA Common
 
                                       43
<PAGE>   57
 
Stock as the holder of such IQ Stock Option would have been entitled to receive
pursuant to the Merger had such holder exercised such option in full immediately
prior to the Effective Time (rounded downward to the nearest whole number) at a
price per share (rounded upward to the nearest whole cent) equal to (x) the
aggregate exercise price for the shares of IQ Common Stock purchasable pursuant
to such IQ Stock Option immediately prior to the Effective Time divided by (y)
the number of whole shares of IA Common Stock deemed purchasable pursuant to
such IQ Stock Option as determined above. As of August 14, 1998, options to
acquire 664,275 shares of IQ Common Stock were outstanding.
 
     Certain of the outstanding stock option agreements held by IQ executive
officers provide for the acceleration of existing vesting provisions in the
event of a change of control of IQ such as the Merger. These options provide for
the purchase of up to 45,000 additional shares of IQ Common Stock at prices
ranging from $6.81 to $12.00.
 
     At the Effective Time, the combined company will assume (i) the IQ Stock
Options and (ii) IQ's Stock Option Plans as in effect as of the date of the Plan
of Merger and all obligations under such plans. Under the Plan of Merger, IA has
agreed to reserve for issuance a sufficient number of shares of IA Common Stock
for delivery under such IQ Stock Plans assumed as described above. As soon as
practicable after the Effective Time, IA shall file a registration statement on
Form S-8, with respect to the shares of IA Common Stock subject to such options
and shall use its best efforts to maintain the effectiveness of such
registration statement for so long as such options remain outstanding.
 
DIRECTOR AND OFFICER INDEMNIFICATION
 
     The Plan of Merger provides that, from and after the Effective Time, the
surviving corporation shall indemnify and hold harmless each present and former
director and officer of IQ against all costs or expenses (including attorneys'
fees), judgments, fines, losses, claims, damages, liabilities or amounts paid in
settlement incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative arising
out of or pertaining to matters existing or occurring at or prior to the
Effective Time, whether asserted or claimed prior to, at or after the Effective
Time, to the fullest extent that IQ would have been permitted under GCC and its
Articles of Incorporation, Bylaws or resolutions of the IQ Board in effect on
the date of the Plan of Merger to indemnify such person and the surviving
corporation shall also be obligated to advance expenses as incurred to the
fullest extent permitted under applicable law, provided the person to whom
expenses are advanced provides an undertaking to repay such advances if it is
ultimately determined that such person is not entitled to indemnification.
 
EMPLOYMENT AGREEMENT
 
     The Plan of Merger provides that Charles R. Chitty, the Chairman of the
Board, President and Chief Executive Officer of IQ shall become a member of the
Board of Directors of IA following the Effective Time. In addition, pursuant to
the Plan of Merger, IA and Mr. Chitty have entered into an employment agreement,
to be effective upon the Effective Time, governing Mr. Chitty's employment with
IA. Mr. Chitty will serve as IA's Senior Vice President of Vertical
Applications. The term of Mr. Chitty's employment will commence on the date of
the Merger and continue until October 31, 1999. Mr. Chitty has also agreed that
at the end of the term of the employment agreement he will provide two-years of
consulting services commencing November 1, 1999 and continuing until October 31,
2001. Under the agreement Mr. Chitty will receive annual salaries of $225,000,
$235,000 and $175,000 through October 31, 2001. In addition, Mr. Chitty will be
eligible for bonuses, benefits and the grant of a stock option to purchase
20,000 shares of IA Common Stock under the IA 1997 Equity Incentive Plan. For
1998, Mr. Chitty's bonus plan is based upon his pre-existing compensation plan
with IQ. IA may terminate Mr. Chitty's employment for cause without notice and
without any further obligation to Mr. Chitty, and Mr. Chitty may terminate the
agreement if IA materially breaches the agreement. Mr. Chitty's options vest
over five years, provided that vesting of the options shall accelerate if Mr.
Chitty is not nominated to remain as a director of IA during such five-year
period or in the event of a Change of Control (as defined in the Employment
Agreement) of IA. Mr. Chitty has also agreed to execute IA's standard
noncompetition agreement to be applicable for the term of the employment and
consulting agreements.

RESELLER AGREEMENT
 
     The Plan of Merger provides that before the consummation of the Merger, IA

software products and to employ, train and maintain adequate personnel to
promote the IQ software products. IQ has agreed among other things, to provide
certain training and sales support to IA and to provide certain maintenance and
support services to licensees of the IQ software products.

Time, whether before or after approval of the matters presented in connection
with the Merger by the stockholders of IA and IQ:
 
          (a) by mutual written consent of IA and IQ; or
 
          (b) by either IA or IQ if the Merger shall not have been consummated
     by November 30, 1998 (the "Outside Date") (provided that the right to
     terminate the Plan of Merger under this clause shall not be available to
     any party whose failure to fulfill any obligation under the Plan of Merger
     has been a significant cause of or resulted in the failure of the Merger to
     occur on or before such date); or
 
          (c) by either IA or IQ if a court of competent jurisdiction or other
     Governmental Entity (as defined in the Plan of Merger) shall have issued a
     nonappealable final order, decree or ruling or taken any other
     nonappealable final action, in each case having the effect of permanently
     restraining, enjoining or otherwise prohibiting the Merger; or
 
          (d) by IA if, at the IQ Special Meeting (including any adjournment or
     postponement), the requisite vote of the stockholders of IQ in favor of the
     Plan of Merger and the Merger shall not have been obtained; or by IQ if, at
     the IA Special Meeting (including any adjournment or postponement), the
     requisite vote of the stockholders of IA in favor of the Plan of Merger and
     the Merger shall not have been obtained (provided that the right to
     terminate the agreement under this provision shall not be available to (i)
     IA where the failure to obtain IA stockholder approval shall have been
     caused by the action or failure to act of IA and such action or failure to
     act constitutes a material breach by IA of the Plan of Merger, or (ii) IQ
     where the failure to obtain IQ stockholder approval shall have been caused
     by the action or failure to act of IQ and such action or failure to act
     constitutes a material breach by IQ of the Plan of Merger); or
 
          (e) by IA, if (i) the IQ Board shall have withdrawn or modified its
     recommendation of the Plan of Merger or the Merger; (ii) the IQ Board shall
     have recommended to the stockholders of IQ an Alternative Transaction;
     (iii) a tender offer or exchange offer for 20% or more of the outstanding
     shares of IQ Common Stock is commenced (other than by IA or an affiliate of
     IA) and the IQ Board recommends that the stockholders of IQ tender their
     shares in such tender or exchange offer; or (iv) for any reason IQ fails to
     call and hold the IQ Special Meeting by the Outside Date (provided that
     IA's right
 
                                       46
<PAGE>   60
 
     to terminate the Plan of Merger under such clause (iv) shall not be
     available if at such time IQ would be entitled to terminate the Plan of
     Merger by reason of a breach by IA of section (f) or (g) hereunder); or
 
          (f) by IQ, if (i) the IA Board shall have withdrawn or modified its
     recommendation of the Plan of Merger or the Merger or (ii) for any other
     reason IA fails to call and hold the IA Special Meeting by the Outside Date
     (provided that IQ's right to terminate the Plan of Merger under such clause
     (ii) shall not be available if at such time IA would be entitled to
     terminate the Plan of Merger under section(e) or (g) hereunder); or
 
          (g) by IA or IQ, if there has been a breach of any representation,
     warranty, covenant or agreement on the part of the other party set forth in
     the Plan of Merger, which breach (i) causes certain IQ conditions (in the
     case of a termination by IA) or IA conditions (in the case of a termination
     by IQ) not to be satisfied and (ii) shall not have been cured within 20
     business days (or prior to November 30, 1998, if earlier) following receipt
     by the breaching party of written notice of such breach from the other
     party.
 
     In the event of termination of the Plan of Merger by either IA or IQ as
provided above, the Plan of Merger will become void and there will be no
liability or obligation on the part of IA, IQ, Merger Sub or their respective
officers, directors, stockholders or Affiliates, except as provided below with
respect to expense reimbursements and termination fees.
 
     Except as set forth below, whether or not the Merger is consummated, all
fees, costs and expenses incurred in connection with the Plan of Merger and the
transactions contemplated thereby shall be paid by the party incurring such
expenses, provided, however, that IA and IQ shall share equally all fees and
expenses, other than accountants' and attorneys' fees, incurred in relation to
printing and filing of this Joint Proxy Statement/Prospectus (including any
related preliminary materials) and the related Registration Statement (including
financial statements and exhibits) and any amendments or supplements.
 
     IQ shall pay IA a termination fee (the "Termination Fee") of $2,240,000 in
immediately available funds within five business days after the termination of
the Plan of Merger by IA under the circumstances described in paragraph (e)
above.
 
     IA shall pay IQ a termination fee in an amount equal to IQ's out-of-pocket
costs (including reasonable attorney and accountant fees) incurred in connection
with the transactions contemplated by the Plan of Merger (but in no event in
excess of $450,000) in immediately available funds within five business days
after the termination of the Plan of Merger by IQ pursuant to paragraph (f)
above.
 
CLOSING
 
     The Merger will be completed on the date that the Certificate of Merger is
filed with the Office of the Secretary of State of the State of Georgia. The
Effective Time is expected to occur as soon as practicable after the receipt of
the necessary approvals at the IA Special Meeting and the IQ Special Meeting and
satisfaction or waiver of the other conditions precedent to the Merger, as set
forth in the Plan of Merger. It is anticipated that the Closing will occur
promptly after obtaining the necessary approvals at the IA Special Meeting and
the IQ Special Meeting.
 
AMENDMENT AND WAIVER
 
     The Plan of Merger may be amended at any time by action taken or authorized
by the respective IA and IQ Boards, but after approval by the stockholders of IA
or IQ of the Merger, no amendment shall be made which by law requires further
approval by such stockholders, without such further approval. IA and IQ, by
action taken or authorized by their respective Boards of Directors, may extend
the time for performance of the obligations or other acts of the other parties
to the Plan of Merger, may waive any inaccuracies in the representations or
warranties contained in the Plan of Merger or in any document delivered pursuant
to the Plan of Merger and may waive compliance with any agreements or conditions
contained in the Plan of Merger.

STOCK OPTION AGREEMENT
 
     The following is a brief summary of the terms of the Stock Option
Agreement, a copy of which is included as an exhibit to the Plan of Merger and
incorporated herein by reference. This summary is qualified in its entirety by
reference to the Stock Option Agreement.
 
     Pursuant to the Stock Option Agreement, IA has the right (the "Option"),
under the circumstances described below, to acquire up to 930,169 shares of
authorized but unissued IQ Common Stock (the "Option Shares") (or approximately
19.9% of the outstanding IQ Common Stock as of the date of execution of the
Stock Option Agreement prior to giving effect to the exercise of such option),
at the lowest of (i) $11.75 per share, (ii) the average closing price of IQ
Common Stock on the Nasdaq National Market for the five consecutive trading days
beginning on and including the day that the Merger is publicly announced, and
(iii) the average closing price of IQ Common Stock on the Nasdaq National Market
for the five consecutive trading days immediately preceding the public
announcement of an Alternative Transaction involving IQ which gives rise to the
right to exercise the option (the "Option Price"). The Stock Option Agreement
could have the effect of making an acquisition of IQ by a third party more
costly because of the need to acquire in any such transaction the Option Shares,
and could also jeopardize the ability of a third party to acquire IQ in a
transaction accounted for as a pooling of interests.
 
     The Option may be exercised by IA, in whole or in part, at any time or from
time to time after the occurrence of an event which would entitle IA, upon
termination of the Plan of Merger, to payment of the Termination Fee (as
described in "-- Termination; Termination Fees and Expenses" above). IA may
exercise the Option by either (a) paying the Option Price in cash and receiving
the Option Shares or (b) electing, in lieu of the payment of the Option Price
and the receipt of the Option Shares, to receive a cash payment (the "Cash
Exercise Payment") from IQ in the amount of the excess of (i) the higher of the
price paid for the IQ Common Stock in an Alternative Transaction or the then
current market price of the IQ Common Stock over (ii) the Option Price.
 
     Upon exercise by IA of the Option for at least 465,085 shares of IQ Common
Stock, IA shall be entitled to designate one person to be appointed to the IQ
Board, and IQ shall (subject to certain limitations) cause such designee to be
appointed to the IQ Board.
 
     In the event IA exercises the Option in whole or in part, IQ shall have a
right of first refusal with respect to certain sales by IA of the Option Shares
prior to the earlier of the first anniversary of the termination of the Plan of
Merger or the occurrence of a change in control event (as defined in the Stock
Option Agreement) with respect to IQ.
 
     The Stock Option Agreement further provides that if IA desires to sell any
of the Option Shares within two years after the purchase of such shares and such
sale requires the registration of such shares under the Securities Act, IQ shall
be required to prepare and file (subject to certain limitations) a registration
statement under the Securities Act for the purpose of permitting such sale of
shares by IA. IQ shall not be required to have declared effective more than two
such registration statements.
 
     Notwithstanding any other provisions of the Stock Option Agreement, in no
event shall IA's Total Profit (as defined below) exceed $3,200,000. "Total
Profit" means the aggregate amount (before taxes) of the Termination Fee
received by IA, and the net cash amounts received by IA pursuant to the sale of
Option Shares to any unaffiliated party, less the purchase price paid by IA for
such shares.
 
     The Option shall terminate upon the earlier of (i) the Effective Time, (ii)
the date on which IA realizes a Total Profit of $3,200,000, (iii) 180 days after
the termination of the Plan of Merger or (iv) the termination of the Plan of
Merger, in the event the Plan of Merger is terminated by IQ pursuant to
paragraph (g) in "-- Termination; Termination Fees and Expenses"; provided that
if the Option cannot be exercised or the Shares cannot be delivered to IA
because certain conditions have not yet been satisfied, the date referred to in
clause (iii) above shall be extended until 30 days after such impediment to
exercise has been removed.

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion summarizes the material federal income tax
considerations relevant to the Merger that are applicable to holders of IQ
Common Stock. This discussion is based on currently existing provisions of the
Code, existing Treasury Regulations thereunder and current administrative
rulings and court decisions, all of which are subject to change. Any such
change, which may or may not be retroactive, could alter the tax consequences to
IA, IQ or IQ's stockholders as described herein.
 
     IQ stockholders should be aware that this discussion does not deal with all
federal income tax considerations that may be relevant to particular IQ
stockholders in light of their particular circumstances, such as stockholders
who are dealers in securities, who are subject to the alternative minimum tax
provisions of the Code, who are insurance companies or financial institutions,
who are foreign persons or entities, who do not hold their IQ Common Stock as
capital assets, who acquired their shares in connection with stock option or
stock purchase plans or in other compensatory transactions, who hold IQ Common
Stock as part of an integrated investment (including a "straddle") comprised of
shares of IQ Common Stock and one or more other positions, or who have
previously entered into a transaction deemed to result in a constructive sale of
IQ Common Stock under the Code. In addition, the following discussion does not
address the tax consequences of the Merger under foreign, state or local tax
laws, the tax consequences of transactions effectuated prior or subsequent to,
or concurrently with, the Merger (whether or not any such transactions are
undertaken in connection with the Merger), including without limitation any
transaction in which shares of IQ Common Stock are acquired or shares of IA
Common Stock are disposed of, or the tax consequences of the assumption by IA of
outstanding options and subscriptions to acquire IQ Common Stock. ACCORDINGLY,
IQ STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC
TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL
AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER.
 
     The consummation of the Merger is conditioned upon Gunderson Dettmer and
Miller & Martin delivering opinions (the "Final Tax Opinions") at the Closing to
IA and IQ, respectively, based upon facts and factual representations of IA,
Merger Sub and IQ as of the Closing Date. Assuming the Merger is a
Reorganization, then, subject to certain assumptions, limitations and
qualifications, the Merger should result in the following federal income tax
consequences:
 
          (a) No gain or loss will be recognized by holders of IQ Common Stock
     solely upon their receipt in the Merger of IA Common Stock in exchange
     therefor (except to the extent of cash received in lieu of a fractional
     share of IA Common Stock).
 
          (b) The aggregate tax basis of the IA Common Stock received by IQ
     stockholders in the Merger (including any fractional share of IA Common
     Stock not actually received) will be the same as the aggregate tax basis of
     the IQ Common Stock surrendered in exchange therefor.
 
          (c) The holding period of the IA Common Stock received by each IQ
     stockholder in the Merger will include the period for which the IQ Common
     Stock surrendered in exchange therefor was considered to be held, provided
     that the IQ Common Stock so surrendered is held as a capital asset at the
     time of the Merger.
 
          (d) Cash payments received by holders of IQ Common Stock in lieu of a
     fractional share will be treated as if such fractional share of IA Common
     Stock had been issued in the Merger and then redeemed by the combined
     company. An IQ stockholder receiving such cash will recognize gain or loss,
     with respect to such payment, measured by the difference (if any) between
     the amount of cash received and the basis in such fractional share.
 
          (e) Each of IA, Merger Sub and IQ will be a party to the
     Reorganization, and as such will not recognize material amounts of gain or
     loss directly as a result of the Merger.
 
     Although IA and IQ will receive the Final Tax Opinions from their
respective counsel that the Merger will be treated as a Reorganization, a
recipient of shares of IA Common Stock could recognize gain to the extent that
such shares were considered to be received in exchange for services or property
(other than solely
 
                                       49
<PAGE>   63
 
IQ Common Stock). All or a portion of such gain may be taxable as ordinary
income. Gain could also have to be recognized to the extent that a IQ
stockholder was treated as receiving (directly or indirectly) consideration
other than IA Common Stock in exchange for such stockholder's IQ Common Stock.
 
     The parties will not request a ruling from the Internal Revenue Service
(the "IRS") in connection with the Merger. IQ stockholders should be aware that
neither the Exhibit Tax Opinions nor the Final Tax Opinions bind the IRS and the
IRS is therefore not precluded from successfully asserting a contrary opinion.
In addition, the Final Tax Opinions are subject to certain assumptions,
limitations and qualifications, including but not limited to the truth and
accuracy of certain representations made by IA, IQ and Merger Sub, including
representations in certain certificates to be delivered to counsel by the
respective managements of IA, IQ and Merger Sub.
 
     A successful IRS challenge to the Reorganization status of the Merger would
result in IQ stockholders recognizing taxable gain or loss with respect to each
share of IQ Common Stock surrendered equal to the difference between the
stockholder's basis in such share and the fair market value, as of the Effective
Time, of the IA Common Stock received in exchange therefor. In such event, a
stockholder's aggregate basis in the IA Common Stock so received would equal its
fair market value as of the Effective Time, and the stockholder's holding period
for such stock would begin the day after the Merger.
 
ACCOUNTING TREATMENT
 
     The Merger is intended to qualify as a pooling of interests for accounting
purposes. Under this method of accounting, the recorded assets and liabilities
of IA and IQ will be carried forward to the combined company at their recorded
amounts, the operating results of the combined company will include the
operating results of IA and IQ for the entire fiscal year in which the
combination occurs, and the reported operating results of the separate companies
for prior periods will be combined and restated as the operating results of the
combined company. Each of the affiliates of IA and IQ has executed a written
agreement to the effect that such person will not transfer shares of common
stock of either IA or IQ during the period beginning 30 days prior to the
Effective Time and ending on the date that IA publishes financial statements,
which reflect 30 days of operations of the combined company (which agreements
relate to the ability of the combined company to account for the Merger as a
pooling of interests). See "-- Resale of IA Common Stock; Agreements with
Affiliates" and "Risk Factors -- Pooling of Interests."
 
     It is a condition to the consummation of the Merger that, among other
things, the Merger qualify as a pooling of interests accounting under Accounting
Principles Board Opinion No. 16.

                            IQ SOFTWARE CORPORATION
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     The following unaudited pro forma condensed combined financial statements
have been prepared to give effect to the Merger, using the pooling-of-interests
method of accounting. IA's and IQ's fiscal years end on January 31.
 
     The unaudited pro forma condensed combined balance sheet gives effect to
the Merger as if it had occurred on July 31, 1998 and combines the unaudited
consolidated balance sheet of IA and the unaudited condensed consolidated
balance sheet of IQ as of July 31, 1998.
 
     The unaudited pro forma condensed combined statements of operations give
effect to the Merger as if it occurred as of the beginning of the earliest year
presented. The unaudited pro forma condensed combined statements of operations
for the fiscal years ended January 31, 1996, 1997 and 1998 combine IA's
historical statements of operations for the fiscal years ended January 31, 1996,
1997 and 1998 with IQ's historical statements of operations for the fiscal years
ended January 31, 1996, 1997 and 1998. The unaudited pro forma condensed
combined statements of operations for the six months ended July 31, 1997 and
1998 combine IA's historical unaudited statements of operations for the six
months ended July 31, 1997 and 1998 with IQ's historical unaudited statements of
income for the six months ended July 31, 1997 and 1998.
 
     IA estimates that it will incur transaction costs of approximately $7.1
million associated with the Merger, which will be charged to operations when
incurred. There can be no assurance that the combined company will not incur
additional charges to reflect costs associated with the Merger or that
management will be successful in its efforts to integrate the operations of the
two companies. See "Risk Factors -- Cost of Integration; Transaction Expenses."
 
     The following unaudited pro forma condensed combined financial information
is presented for illustrative purposes only and is not necessarily indicative of
the financial position or results of operations that would have actually been
reported had the Merger occurred at the beginning of the periods presented, nor
is it necessarily indicative of future financial position or results of
operations. These unaudited pro forma condensed combined financial statements
are based upon the respective historical consolidated financial statements of IA
and IQ and should be read in conjunction with the respective historical
consolidated financial statements and notes thereto incorporated by reference in
this Joint Proxy Statement/Prospectus, and do not incorporate, nor do they
assume, any benefits from cost savings or synergies of operations of the
combined company.

                    CONDENSED COMBINED FINANCIAL STATEMENTS
 
 1. PERIODS PRESENTED
 
     IA's and IQ's fiscal years end on January 31. The unaudited pro forma
condensed combined statements of operations give effect to the Merger as if it
occurred as of the beginning of the earliest period presented. The unaudited pro
forma condensed combined balance sheet gives effect to the Merger as if it had
occurred on July 31, 1998, and is based upon the historical balance sheet data
of IA and IQ as of July 31, 1998.
 
 2. PRO FORMA EARNINGS PER SHARE
 
     The unaudited pro forma combined earnings per share data is based upon the
weighted average number of common and potential common shares outstanding of IA
and IQ for each period using an Exchange Ratio of 1.96 shares of IA Common Stock
for each share of IQ Common Stock.
 
 3. CONFORMING ADJUSTMENTS AND INTERCOMPANY TRANSACTIONS
 
     There were no material adjustments required to conform the accounting
policies of IA and IQ. Certain amounts have been reclassified to conform to the
pro forma presentation. There are no material intercompany transactions included
in the unaudited pro forma condensed combined financial statements.
 
 4. TRANSACTION COSTS
 
     It is estimated that the combined company will incur charges to operations
related to the Merger currently estimated to be $7.1 million, principally in the
quarter in which the Merger is consummated. These charges include direct
transaction costs, primarily for financial advisory, accounting and legal
services, printing expenses, filing fees and other Merger-related costs. The
estimated charge is reflected in the pro forma balance sheet but is not
reflected in the unaudited pro forma condensed combined statements of
operations. This charge is a preliminary estimate only, and is, therefore,
subject to change. See "Risk Factors -- Cost of Integration; Transaction
Expenses."
 
 5. ISSUANCE OF IA COMMON STOCK
 
     The unaudited pro forma condensed combined financial statements reflect the
issuance of 1.96 shares of IA Common Stock for each share of IQ Common Stock
outstanding. The following table sets forth the pro forma share issuances in
connection with the Merger (shares in thousands):

BUSINESS
 
OVERVIEW
 
     IA develops, markets and supports enterprise scalable OLAP software that is
designed to allow a large number of users to access and analyze large amounts of
data to make quicker and more informed business decisions. IA's server-based
solution, DecisionSuite, provides powerful, robust and flexible analysis
processing capabilities that transform raw data into meaningful information from
a wide range of desktop and Internet platforms. Through the use of an advanced
architecture, IA designed DecisionSuite to accommodate terabytes of data and
thousands of active users. DecisionSuite enables organizations to push effective
decision making to all levels of users thereby creating an "intelligent
enterprise," one capable of quickly identifying and reacting to market
opportunities. DecisionSuite supports many UNIX operating systems and employs
relational database technology, allowing it to access most popular databases,
data warehouses and data marts.
 
INDUSTRY BACKGROUND
 
     In order to compete effectively in today's global environment, businesses
must quickly identify and respond to changing market conditions and are,
therefore, dependent upon their ability to rapidly collect, organize, access and
analyze large amounts of data. Organizations are now collecting not only
internal financial and operational data, but are also collecting large amounts
of historical data on their customers, suppliers and other external sources. At
the same time, to more quickly react to changing business conditions, many
organizations have been flattening their organizational structures and
empowering employees at all levels to make decisions. The desire to distribute
decision making throughout all levels of an organization has created a need by
more people to access the vast amounts of business data collected each day. In
addition to data access, organizations also face the challenges of performing
complex computational analysis on the collected data, and disseminating
information broadly to employees, customers, suppliers and others.
 
     To meet these challenges, organizations have implemented a number of
technology solutions, including data warehouses and data marts, query and
reporting tools and OLAP applications. According to IDC, an independent industry
analyst, the information access segment of the data warehousing market alone is
estimated to be growing from $664 million in 1996 to $1.4 billion in 2000. Data
warehouses and data marts are repositories of summarized historical data often
extracted from disparate departmental or enterprise databases. Data warehouses
and data marts store data in a format optimized for analysis and are frequently
implemented in conjunction with query and reporting tools designed to provide
end users with a means to retrieve data and perform certain pre-defined queries
and simple calculations. This level of analysis, however, is limited (for
example, query and reporting tools generally are not designed to perform
time-series analysis such as calculations of the weekly changes in market share
by region) and these tools often require users to understand the technical
aspects of data storage and data structures. As a result, the use of data query
and reporting tools is often limited to highly trained technical users.
 
     In recent years, OLAP solutions have emerged to provide a means to analyze
complex data along a more intuitive set of business rules and dimensions (for
example, profitability analysis by product, channel, geography, customer or
fiscal period). In addition, by insulating the user from the technical aspects
of data storage and data structures, OLAP solutions enable less technically
sophisticated users within an organization to perform their own analysis.
Typically, OLAP solutions also provide more complex computational capabilities,
including sophisticated time-series analysis, as well as ad hoc, drill-down and
interactive analysis (for example, a marketing manager identifying a market
share reduction can drill down to isolate the problem to a specific product at a
specific store).
 
     Today, two primary OLAP architectures exist: desktop OLAP and server-based
OLAP. Desktop OLAP provides a quick, low-cost solution for applications that do
not require complex analytical capabilities and involve small data sets that do
not require frequent updates. Desktop OLAP solutions are designed for a limited
number of active users and are typically used for personal analysis.
Server-based OLAP solutions are better suited for larger data sets and more
complex analysis. Because server-based OLAP does not require the
 
                                       56
<PAGE>   70
 
movement of large amounts of data to the desktop, it provides greater security
and reduces network traffic, thereby accommodating a larger number of active
users. One approach to server-based solutions utilizes proprietary,
non-relational, highly-indexed database technology. This approach is best suited
for workgroups and departments requiring fast access to medium-sized data sets
(e.g., tens of gigabytes of data) but often is not scalable to accommodate a
large number of concurrent users, is not capable of loading, storing or
analyzing large amounts of data (e.g., hundreds of gigabytes to terabytes of
data) and cannot efficiently update data sets on a frequent basis. In addition,
these solutions often require the data to be loaded in a pre-defined structure
thereby limiting the ability to perform ad hoc queries. The second approach to
server-based OLAP employs existing relational database technology. This approach
allows access to larger amounts of data and provides greater flexibility in
performing ad hoc queries than non-relational database technologies.
 
     At the same time OLAP has emerged as a means to collect, organize, access
and analyze large amounts of data, the emergence of client/server and Internet
technologies has enabled organizations to create infrastructures through which
they can disseminate information throughout their enterprise as well as to
external sources. Client/server computing has provided many employees in an
organization with desktop access to critical information resources through
easy-to-use graphical user interfaces. The emergence of Internet technologies
has provided organizations with a less expensive means to reach an even larger
audience in real time and to securely disseminate information not only to
employees, but also to external business affiliates, such as customers,
suppliers and others.
 
     Organizations are seeking ways to extend the benefits of OLAP in order to
empower employees and other users at all levels to make better business
decisions and react faster to market opportunities. To effectively deliver OLAP
capabilities throughout the enterprise, the solution must support large data
sets, thousands of active users, and simple as well as complex analysis.
Moreover, organizations require enterprise OLAP solutions with efficient and
cost effective deployment and maintenance, and compliance with industry
standards, thereby enabling integration with hardware and software from a
variety of vendors.
 
THE INFORMATION ADVANTAGE SOLUTION
 
     IA develops, markets and supports enterprise scalable OLAP software that is
designed to allow large numbers of users to access and analyze large data sets.
IA's relational server-based solution, DecisionSuite, provides powerful, robust
and flexible analysis processing capabilities that transform raw data into
meaningful information from a wide range of desktop and Internet platforms.
Through the use of an advanced architecture, IA designed DecisionSuite to
accommodate terabytes of data and thousands of active users. DecisionSuite
enables organizations to push effective decision making to all levels of users
thereby creating an "intelligent enterprise," one capable of quickly identifying
and reacting to market opportunities. Key attributes of the DecisionSuite
solution include:
 
     Large Amounts of Data. DecisionSuite employs relational database technology
which IA believes is the only available database technology suitable for
supporting large databases (e.g., hundreds of gigabytes to terabytes of data) or
databases that require frequent updates and access to terabytes of centralized
or distributed data. DecisionSuite processes data on the server and disseminates
the derived results to the user.
 
     Large Number of Users. The DecisionSuite architecture uses sophisticated
partitioning technology to balance the data processing between the database and
the application server. Application partitioning is designed to maximize the
performance and analytical capabilities as the database grows and the number of
concurrent users increases. DecisionSuite's calculation processor is designed to
perform sophisticated business calculations on raw data without overburdening
the relational database with the use of inefficient temporary tables, thereby
increasing the number of users who can concurrently access the data.
 
     Powerful Analytical Capability. DecisionSuite includes a powerful C++ OLAP
calculation processor that provides comprehensive multidimensional, yet
intuitive, analysis capabilities using advanced formula-based business rules. By
avoiding an over-reliance on structured query language ("SQL") for business
calculations, DecisionSuite is designed to provide powerful analytical
capabilities in a scalable architecture. DecisionSuite allows users to join data
from multiple distributed relational databases and create agents that
automatically inform them of changes in market data or from user-defined norms.
 
                                       57
<PAGE>   71
 
     Mass Deployment for the Intelligent Enterprise. IA provides for efficient
and cost-effective deployment and maintenance of DecisionSuite by using a
thin-client architecture where minimal application code is deployed to, and
maintained on, the user's desktop. As a result, organizations can more
effectively deploy and support DecisionSuite over thousands of networked users.
 
     Open Architecture. DecisionSuite was designed to integrate with most
popular tools, databases and platforms provided by other vendors. DecisionSuite
runs on the following server operating systems: HP-UX, Sun Solaris, IBM AIX, NCR
SVR4, SGI IRIX, Sequent DYNIX/ptx and Unisys SVR4; and accesses the following
relational database platforms: Oracle, Red Brick Warehouse, HP-Intelligent
Warehouse, IBM DB2 6000, IBM DB2 Parallel Edition, Informix, NCR Teradata DBS,
Sybase, Sybase IQ and Tandem Non-Stop SQL. As a result, organizations
implementing DecisionSuite can leverage their often significant investment in
existing operating systems and database technologies.
 
     To complement its advanced product offerings, IA has developed a highly
trained customer support staff with technical competencies in a variety of
areas, including UNIX operating systems, database management, distributed
computing and multidimensional analysis. IA believes that to enable its
customers to effectively develop and deploy OLAP applications, it must provide
training and consulting services in these and other areas. Accordingly, IA has
established an extensive customer services group consisting of technical
support, education, implementation, prototyping workshops and other advanced
services (including customized enhancements, content development and performance
assessment).

     DecisionSuite can be used across a range of industries and is typically
used in three types of applications: (a) customer analysis, including
applications for analyzing customer buying patterns, database marketing and
campaign management; (b) product analysis, including sales analysis, inventory
management and promotion management; and (c) operational analysis, including
financial analysis, activity-based costing, forecasting and budgeting. The
following illustrates the variety of ways customers have deployed DecisionSuite:
 
     Financial Services: An international credit card company sought to
differentiate itself from its competitors by offering its 22,000 member
financial institutions the ability to access and analyze credit card transaction
activity and trends online. The goal was to provide member financial
institutions with customer usage data to facilitate and evaluate target
marketing campaigns. This customer's Oracle database contains approximately 1.6
terabytes of data and uses NCR servers. Because of the number of potential
users, the size of the data warehouse and the fact that over 11 million
transactions are added to the database daily, scalability was paramount.
DecisionSuite was selected to provide the OLAP engine necessary to build this
application. IA believes that DecisionSuite was chosen because of the expertise
of its support personnel and the proven scalability, security and ease of use of
the product for the end-user. The first application of DecisionSuite was
available for deployment to members within six months of the date DecisionSuite
was selected and now allows the customer's clients to track usage patterns and
focus their efforts accordingly.
 
     Insurance: A provider of auto insurance claim software, data and services
sought to offer over 350 auto insurance companies the ability to access and
analyze insurance claim data via the Web as an extranet. This customer uses a
Red Brick database and a Sun server. IA believes that DecisionSuite was selected
primarily for its Web and agent capabilities and its ability to efficiently
manage large amounts of data at a granular level. DecisionSuite allows the
customer's sales associates to analyze the claims data for potential clients via
the Web as a tool in the sales process. Upon complete implementation, this
application will also allow auto insurance companies to access and analyze the
customer's nationwide insurance claim data, including repair cycle times and
amounts paid for vehicle parts, and to compare their claims resolution
performance against industry averages and historical trends.
 
     Retail: A multi-billion dollar retailer of electronics with over 6,800
retail stores nationwide sought to deliver online analysis of its consumer and
product data throughout the organization. The customer's warehouse includes
consumer and census data, as well as behavioral and point-of-sale information
from its retail stores. The consumer database alone includes profiles of over
150 million consumers, making the customer's database one of the most
comprehensive marketing databases in the world. This customer uses a Red Brick
database and an HP server. IA believes that DecisionSuite was selected for its
complex analytical capabilities, its Web accessibility and its ability to handle
terabytes of data. DecisionSuite provides online analysis of the databases and
allows the customer's headquarters to analyze the retail stores' performance,
improve inventory controls and target promotional mailings. In addition, this
customer plans to make this application available to its retail store managers
using a standard Web browser, thereby enabling these teams to participate in the
decision making process to improve the store's performance.
 
     Packaged Goods: A leading packaged food company, with more than 200 brands
and 1,000 products in 85 countries, sought to provide better and faster sales
and product information to its sales representatives. Its application required
not only the ability to access multiple, disparate databases (Red Brick and DB2)
that used IBM servers, but it required the ability to deliver both detailed and
summarized key account information to thousands of users. The client selected
DecisionSuite and has currently deployed the system to approximately 2,500 sales
representatives throughout the organization. Using DecisionSuite, the customer's
sales representatives are now able to access and analyze online product sales
by, among other things, location and season. This enables the customer to
anticipate inventory fluctuations, thereby improving inventory controls, and
provides the sales representatives with timely decision making information, such
as which products are likely to sell and when, that often leads to new business
opportunities.
 
PRODUCTS AND TECHNOLOGY
 
     IA's DecisionSuite products are comprised of a server capable of handling
large data sets or large numbers of concurrent users, several desktop products
designed to deliver information to variously skilled end
 
                                       61
<PAGE>   75
 
users over client/server and Internet architectures, and several systems
management, connectivity and database driver modules. IA also offers an advanced
tool kit for the rapid assembly of custom OLAP applications. IA's products are
available on most popular UNIX platforms, including HP-UX, Sun Solaris, IBM AIX,
NCR SVR4, SGI IRIX, Sequent DYNIX/ptx and Unisys SVR4, and are able to access
the following databases: Oracle, Red Brick Warehouse, HP-Intelligent Warehouse,
IBM DB2 6000, IBM DB2 Parallel Edition, Informix, NCR Teradata DBS, Sybase,
Sybase IQ and Tandem Non-Stop SQL. IA designed DecisionSuite's architecture to
be well suited for localization in foreign markets. IA licenses its
DecisionSuite software for a one-time license fee determined on a per server,
per named user, and database size basis.
 
DecisionSuite Server
 
     The DecisionSuite Server is a multi-user product designed to allow large
numbers of users to access and analyze large data sets. The DecisionSuite Server
delivers enhanced OLAP services including: agent and exception reporting
functions to push personalized information directly to users; security based on
individual, workgroup and enterprise level user privileges; and group or
personal query controls to minimize system performance degradation caused by
either individuals or user groups. DecisionSuite Server augments SQL with an
efficient and sophisticated C++ calculation processor that is scalable to
thousands of active users and terabytes of data. The DecisionSuite Server's
Concurrent Session Manager is designed to add, manage and delete concurrent
processes initiated by requests from multiple users or agents, allowing
customers to scale DecisionSuite across the enterprise. The DecisionSuite
Server's Metadata model centralizes maintenance and isolates users from
technical complexities by mapping database structures and business rules with
intuitive business descriptions, thereby simplifying user interactions with the
system.
 
     DecisionSuite DB Drivers. DecisionSuite DB Drivers are designed to provide
organizations with the option of connecting DecisionSuite to target relational
databases with either native drivers or ODBC drivers. Each DB Driver accounts
for the unique SQL syntax and query optimizer of each target database while
allowing organizations to easily switch database vendors' products independently
of deployed DecisionSuite applications. DecisionSuite provides DB Drivers for
Oracle, Red Brick Warehouse, HP-Intelligent Warehouse, IBM DB2 6000, IBM DB2
Parallel Edition, Informix, NCR Teradata DBS, Sybase, Sybase IQ, and Tandem
Non-Stop SQL.
 
     Distributed OLAP Engine. DecisionSuite's OLAP Engine uses distributed
processing technology to maximize user concurrency and analytical functionality.
In particular, IA's calculation processor performs sophisticated business
analysis on raw data without overburdening the database with use of inefficient
temporary tables. This capability enables intensive application processing to be
off-loaded from the database so that organizations can effectively scale to
large numbers of users. This capability also allows support of hundreds of
business calculations and functions that are not currently supported in SQL.
 
     Enterprise OLAP Services. DecisionSuite provides essential services
required for enterprise-scale deployments including:
 
     Workgroup Security. The partitioned, server software design of
     DecisionSuite allows additional levels of security provided by an
     application server account. In this manner, users with similar requirements
     are easily added to the system without risk of improper information access.
     Reports, report components and database views are secured at personal,
     workgroup and enterprise levels.
 
     Collaboration. IA's use of object technology enables report data and logic
     to be shared among users. Each report contains the data, assumptions and
     processing logic so that users can interactively exchange and build on each
     other's analysis. This technology facilitates live information sharing
     among users of IA's product.
 
     Report Casting. IA's use of report template technology allows power users
     or information technology personnel to efficiently create a few report
     models for thousands of different reports. Each report template contains
     the instructions and parameters required to generate a single request. Upon
     access, the user profile is used to map the appropriate parameters into the
     instruction set at run-time so that each user
 
                                       62
<PAGE>   76
 
     receives a personalized report. This capability enables the administrator
     to build and maintain a relatively small number of automatically adapting
     report templates, rather than tens of thousands of user specific reports.
 
     Agents. IA's server-centric architecture and multi-user, multi-tasking
     server technology allows DecisionSuite users to design autonomous
     intelligent agents, the results of which can be shared by multiple users.
     These agents are created by users and reside on the server. The agents also
     can be triggered by areas of opportunity or trouble, without affecting
     desktop performance. The results of the agents may be delivered in real
     time to one or more users via e-mail, pager telephone and the Internet so
     their assumptions and results can be explored and challenged, as well as
     shared to reduce the use of system resources for repetitive batch
     processing.
 
DecisionSuite Desktops
 
     DecisionSuite Desktops include an array of products positioned to meet the
varying needs and skill levels of employees in an organization.
 
     WebOLAP. WebOLAP is intended for all users seeking OLAP capability over the
Internet. This product provides ad hoc reporting and OLAP capability using only
a browser, a DecisionSuite user name and a password. WebOLAP's Universal Access
functionality allows users direct access to the DecisionSuite Server from search
engines for seamless integration into corporate Web sites. WebOLAP's codeless
desktop architecture enables it to be used from any desktop with a Web browser,
without requiring a plug-in or extension, eliminating installation and reducing
administration costs in large user environments. Complete integration with the
DecisionSuite Server also allows WebOLAP users to seamlessly share secure,
interactive reports, and collaborate with co-workers using any DecisionSuite
Desktop.
 
     NewsLine. NewsLine is intended for active users to deliver and receive live
information, reports, alerts and intelligent agents. Users of this product can
be alerted to the latest opportunities and problems affecting their business by
software agents that monitor, analyze and filter information 24 hours a day,
seven days a week. For example, users have the ability to drill up, down or
across business dimensions anywhere in the data warehouse then pivot and export
results with a spreadsheet hot-link. NewsLine allows experienced users the
ability to securely view and modify all assumptions underlying the analysis,
including calculations and filters. Users may drag and drop calculations and
filters to review the entire data warehouse. NewsLine has robust business
charting capabilities and can be integrated with external applications,
including operational systems, catalogs and powerful GIS mapping systems.
 
     Analysis. Analysis is intended for power users and provides authoring and
publishing capabilities in addition to all the functionality of NewsLine. This
product allows users to start with a "blank sheet of paper," then point and
click to author and publish filters, calculations, calculation templates,
reports, report templates, distributed intelligent agents, triggers and alerts
as well as navigate throughout the entire data warehouse. Alerts can be directed
and broadcast as "live" interactive reports and as messages via e-mail, pager,
telephone and the Internet. Users are presented information in business terms so
that they can explore gigabytes of information without the technical knowledge
of database structures or SQL.
 
DecisionSuite Workbench
 
     The DecisionSuite Workbench allows database and system administrators to
define, manage and support user profiles, security, and group or personal query
controls, as well as to customize and distribute desktop profiles across the
network. Developers can also use DecisionSuite Workbench to create more
sophisticated intelligent agents, custom applications and add-in functionality,
and to integrate DecisionSuite with operational systems. With DecisionSuite's
thin-client architecture, all applications are centrally managed from the
server, thereby reducing cost of ownership and allowing database and systems
administrators to improve DecisionSuite's efficiency.
 
                                       63
<PAGE>   77
 
DecisionSuite Connections
 
     DecisionSuite Connections provide connectivity with complementary OLAP and
productivity tools. To date, IA had developed DecisionSuite Connections for
Microsoft Excel, Lotus 123 and Brio. These connections provide users of
DecisionSuite Desktops with the ability to automatically download data into
desktop tools. For example, Brio Connection provides users with the ability to
generate a small data cube that is automatically downloaded into Brio's OLAP
desktop, enabling the user to perform interactive analysis, formatting and
charting while disconnected from the network.

environment, staffed with knowledgeable business and technical personnel. Each
workshop utilizes the customer's own data, making the prototyping experience as
realistic as possible. IA believes that a successful implementation of new
technology can be traced to a successful prototype. These prototype systems use
actual company data to assist the business users in identifying the questions
they need to ask but have been unable to visualize. The time and effort to set
up an evaluation environment can be expensive and fraught with technical
infrastructure complexities. IA provides its customers with the training
benefits of prototyping but shields them from such complexities.
 
     Advanced Services. The advanced services group assists in the initial
development of specific solutions for OLAP applications, including
activity-based costing, forecasting, health care analysis and customer
segmentation. This group often provides consultation in the early stages of
modeling and solution-design, combining their strong, technical OLAP expertise,
their in-depth hands-on experience with APIs, and their proven creativity in
architecture and functionality design. Their solutions address the more complex
needs of enterprise OLAP while also focusing on usability and performance for
the end users. Their extensive experience with the APIs have led to the
development of a series of DecisionSuite extensions. These extensions are
optional programs that offer functionality not otherwise available within the
core DecisionSuite product. Extensions consist of either tools for the system
administrator or for the end user.
 
     As of July 31, 1998, IA's services organization consisted of 69 employees
compared to 26, 41 and 65 employees at January 31, 1996, 1997 and 1998,
respectively.

RESEARCH AND DEVELOPMENT
 
     Research and development has provided the foundation for IA's success in
the marketplace, and IA intends to continue to make substantial investments in
research and development and related activities to maintain and enhance its
product lines. IA believes that its future success will, in large part, depend
on its ability to maintain and improve current products, and to develop new
products that meet emerging decision support needs. Research is focused in three
areas: identifying market needs, designing applications for these needs and
implementing such solutions in a reliable and easy-to-use fashion. Current
development activities are focused on product enhancements in several key areas:
OLAP engine, Windows client delivery systems, Internet delivery systems, agent
technology and forecasting. The development group infrastructure provides a full
suite of documentation, quality assurance, delivery and support capabilities (in
addition to its design and implementation functions) for IA's products.
 
     As of July 31, 1998, IA's research and development organization consisted
of 70 employees compared to 32, 45 and 59 employees at January 31, 1996, 1997
and 1998, respectively. Most of the senior members of IA's research and
development organization have been employed by IA since its inception.
 
COMPETITION
 
     The market in which IA competes is intensely competitive, highly fragmented
and characterized by rapidly changing technology and evolving standards. IA's
current and prospective competitors offer a variety of planning and analysis
software solutions and generally fall within three categories: (i) vendors of
desktop OLAP software such as Cognos and Business Objects; (ii) vendors of
multidimensional OLAP software such as Oracle (Express), IA Software, Seagate
(Holos) and SAS; and (iii) vendors of OLAP/relational database software such as
MicroStrategy and Platinum Technology (Prodea). IA has experienced and expects
to continue to experience increased competition from current and potential
competitors, many of whom have significantly greater financial, technical,
marketing and other resources than IA. Such competitors may be able to respond
more quickly to new or emerging technologies and changes in customer
requirements or devote greater resources to the development, promotion and sales
of their products than IA. Also, certain current and potential competitors,
including companies such as Microsoft, IBM, Sybase and Informix, may have
greater name recognition or more extensive customer bases that could be
leveraged. These companies could integrate competing OLAP/relational database
software with other widely accepted products resulting in a loss of market share
for IA. IA expects additional competition as other established and emerging
companies enter into the OLAP software market and new products and technologies
are introduced. Increased competition could result in price reductions, fewer
customer orders, reduced gross margins, longer sales cycles and loss of market
share, any of which would materially adversely affect IA's business, operating
results and financial condition.
 
     Current and potential competitors may make strategic acquisitions or
establish cooperative relationships among themselves or with third parties,
thereby increasing the ability of their products to address the needs of IA's
prospective customers. IA's current or future indirect channel partners may
establish cooperative relationships with current or potential competitors of IA,
thereby limiting IA's ability to sell its products through particular
distribution channels. Accordingly, it is possible that new competitors or
alliances among current and new competitors may emerge and rapidly gain
significant market share. Such competition could materially adversely affect
IA's ability to obtain new licenses, and maintenance and support renewals for
existing licenses, on terms favorable to IA. Further, competitive pressures may
require IA to reduce the price of DecisionSuite, which would materially
adversely affect IA's business, operating results and financial condition. There
can be no assurance that IA will be able to compete successfully against current
and future competitors, and the failure to do so would have a material adverse
effect upon IA's business, operating results and financial condition.
 
     IA competes on the basis of certain factors, including data scalability,
user scalability, open architecture, analytical capabilities, product features,
product performance, product quality, time to market, ease of use, customer
support and price. IA believes it presently competes favorably with respect to
each of these factors. However, IA's market is still evolving and there can be
no assurance that IA will be able to compete
 
                                       66
<PAGE>   80
 
successfully against current and future competitors, and the failure to do so
successfully will have a material adverse effect upon IA's business, operating
results and financial condition. See "Risk Factors -- Competition."
 
INTELLECTUAL PROPERTY RIGHTS
 
     IA relies primarily on a combination of copyright and trademark laws, trade
secrets, confidentiality procedures and contractual provisions to protect its
proprietary technology. For example, IA licenses its software pursuant to signed
license agreements, which impose certain restrictions on licensees' ability to
utilize the software. In addition, IA seeks to avoid disclosure of its trade
secrets, including requiring those persons with access to IA's proprietary
information to execute confidentiality agreements with IA and restricting access
to IA's source code. IA seeks to protect its software, documentation and other
written materials under trade secret and copyright laws, which afford only
limited protection. Despite IA's efforts to protect its proprietary rights,
unauthorized parties may attempt to copy aspects of IA's products or to obtain
and use information that IA regards as proprietary. Policing unauthorized use of
IA's products is difficult, and while IA is unable to determine the extent to
which piracy of its software products exists, software piracy can be expected to
be a persistent problem. In addition, the laws of many countries do not protect
IA's proprietary rights to as great an extent as do the laws of the United
States. There can be no assurance that IA's means of protecting its proprietary
rights will be adequate or that IA's competitors will not independently develop
similar technology.
 
     To date, IA has not been notified that IA's products infringe the
proprietary rights of third parties, but there can be no assurance that third
parties will not claim infringement by IA with respect to current or future
products. IA expects that data warehouse and data mart software product
developers will increasingly be subject to infringement claims as the number of
products and competitors in IA's industry segment grows and the functionality of
products in different industry segments overlaps. Any such claims, with or
without merit, could be time-consuming, result in costly litigation, cause
product shipment delays or require IA to enter into royalty or licensing
agreements. Such royalty or licensing agreements, if required, may not be
available on terms acceptable to IA or at all, which could have a material
adverse effect upon IA's business, operating results and financial condition.
 
     IA provides its products to end users under non-exclusive licenses, which
generally are non-transferable and have a perpetual term. IA generally licenses
its products solely for the customer's internal operations. IA also licenses its
software on an enterprise-wide basis. IA has entered into source code escrow
agreements for its products. Generally, customers are required to obtain
separate licenses for the database management systems they select directly from
the RDBMS vendors. Furthermore, customers must obtain separate licenses for any
spreadsheets or other PC tools they use directly from such other vendors. See
"Risk Factors -- Limited Protection of Proprietary Technology; Risks of
Infringement; Use of Licensed Technology."
 
EMPLOYEES
 
     As of July 31, 1998, IA had a total of 254 employees, of which 221 were
based in the United States, 18 were based in the United Kingdom, 6 were based in
Canada, 1 was based in France and 8 in Germany. Of the total, 93 were engaged in
sales and marketing, 70 were in research and development, 69 were in services,
and 22 were in finance, administration and operations. IA's future performance
depends in significant part upon the continued service of its key technical,
sales and senior management personnel, ten of whom are bound by employment or
severance agreements. None of IA's employees is represented by a labor union. IA
has not experienced any work stoppages and considers its relations with its
employees to be good.
 
PROPERTIES
 
     IA's principal administrative, sales, marketing, support, and research and
development facility is located in approximately 36,500 square feet of space in
Eden Prairie, Minnesota. The lease on this office space expires on June 30,
2002. IA also leases other domestic sales offices throughout the United States,
as well as international offices in Canada, the United Kingdom and Germany. IA
believes that suitable additional or alternative space will be available in the
future on commercially reasonable terms as needed.
 
LEGAL PROCEEDINGS
 
     IA is not currently subject to any material legal proceeding.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
     The following description of IA's financial condition and results of
operations should be read in conjunction with the information included elsewhere
in this Joint Proxy Statement/Prospectus. This description contains certain
forward-looking statements that involve risks and uncertainties. IA's actual
results could differ significantly from the results discussed in the
forward-looking statements as a result of certain of the risk factors set forth
below and elsewhere in this Joint Proxy Statement/Prospectus.
 
OVERVIEW
 
     IA develops, markets and supports enterprise scalable OLAP software that is
designed to allow a large number of users to access and analyze large amounts of
data to make quicker and more informed business decisions. IA's server-based
solution, DecisionSuite, provides powerful, robust and flexible analysis
processing capabilities that transform raw data into meaningful information from
a wide range of desktop and Internet platforms. Through the use of an advanced
architecture, IA designed DecisionSuite to accommodate terabytes of data and
thousands of active users. DecisionSuite enables organizations to push effective
decision making to all levels of users thereby creating an "intelligent
enterprise," one capable of quickly identifying and reacting to market
opportunities. DecisionSuite supports many UNIX operating systems and employs
relational database technology, allowing it to access most popular databases,
data warehouses and data marts.
 
     To date, all of IA's revenues have been derived from licenses of
DecisionSuite and related services. IA expects that sales of DecisionSuite and
related services will continue to account for all of IA's revenues for the
foreseeable future. IA's license revenues are derived from one-time licenses for
the right to use DecisionSuite in perpetuity and are determined on a per server,
per named user and database size basis. IA's service revenues, which have
accounted for approximately one-half of IA's total revenues for the past three
years, include fees for maintenance, training and consulting services. IA
anticipates that service revenues will continue to account for a significant
portion of IA's total revenues.
 
     The American Institute of Certified Public Accountants' has approved
Statement of Position (SOP), SOP 97-2, effective for transactions entered into
after December 15, 1997, which supersedes Statement of Position 91-1, "Software
Revenue Recognition." Management has adopted this new statement and has
determined that its adoption has not had a material effect on the timing of IA's
revenue recognition or cause changes to its revenue recognition policies.
 
     Revenues derived from software licenses are recognized upon execution of a
license agreement, delivery of the software product and fulfillment of other
delivery requirements. Revenues from software provided for demonstration or
pilot purposes are not recognized until execution of a license agreement and
fulfillment of other delivery requirements. Revenues derived from maintenance
contracts, which are bundled with the initial licenses, and all revenues from
extended maintenance contracts are deferred and recognized ratably over the term
of the maintenance contract. Revenues from maintenance contracts are included in
service revenues. Revenue from training and consulting services are recognized
as the services are performed.
 
     IA licenses its software through its direct sales force and increasingly
through or in conjunction with solution development partners, sales affiliates
and marketing partners. Revenues from indirect sales involving strategic
partners accounted for approximately 11.5%, 12.7% and 9.6% of IA's license
revenues for fiscal 1996, 1997 and 1998 and approximately 22.1% and 11.3% of
IA's license revenues for the six months ended July 31, 1997 and 1998,
respectively. IA intends to expand its strategic relationships, thereby
increasing the revenues generated from indirect channels as a percentage of
total license revenues. IA intends to expand its international operations and
has committed, and continues to commit, significant management time and
financial resources to developing direct and indirect international sales and
support channels. IA has international sales and support offices in Toronto,
Canada; London, England; and Koln, Germany. To date, most of IA's international
revenues have been derived from the United Kingdom and Canada.
 
     Although IA's personnel related costs are higher in Europe than they are in
the United States, and IA's international operations are subject to economic,
fiscal and monetary policies of foreign governments, to date, these factors have
not had a material effect on IA's results of operations or liquidity. In
addition, because all of
 
                                       69
<PAGE>   83
 
IA's sales have been denominated in U.S. dollars, IA has been able to minimize
the impact of foreign exchange rate changes. There can be no assurance that IA
will be able to continue to denominate foreign sales in U.S. dollars or that
international operations costs and economic, fiscal and monetary policies of
foreign governments will not in the future have a material adverse effect on
IA's results of operations or liquidity.
 
     Since inception, IA has made significant strategic investments in building
an infrastructure to support long-term growth. IA has more than tripled its
headcount from 75 at January 31, 1995 to 254 at July 31, 1998, reflecting
personnel increases throughout IA. As a result, although IA's revenues have
increased in each of the last ten quarters, IA has incurred net losses in each
quarter since inception, except the quarters ended April 30 and July 31, 1998,
and had an accumulated deficit of $26.4 million as of July 31, 1998.
 
     IA's limited operating history makes the prediction of future operating
results difficult and unreliable. In addition, given its limited operating
history and recent rapid growth, historical growth rates in IA's revenues should
not be considered indicative of future revenue growth rates or operating
results. There can be no assurance that any of IA's business strategies will be
successful or that IA will be able to achieve profitability on a consistent
quarterly or annual basis.

REVENUES
 
     License. License revenues are recognized upon execution of a license
agreement and shipment of the product if no other significant obligations
remain, if payments are due within six months and collection of the resulting
receivable is probable. License revenues were $2.7 million, $6.5 million and
$13.7 million in fiscal 1996, 1997 and 1998, respectively, representing
increases of 141.7% from fiscal 1996 to fiscal 1997, and 110.5% from fiscal 1997
to fiscal 1998. License revenues increased 118.5%, from $5.0 million to $10.9
million, between the six months ended July 31, 1997 and 1998. The increase in
IA's license revenues in each period was attributable primarily to greater
market acceptance of DecisionSuite which led to an increase in volume, an
increase in the average revenues derived from each license as the average number
of seats per customer increased, and an increase in sales headcount. To date,
price increases have not had a significant impact on revenues. IA does not
believe that the historical percentage growth rates of license revenues will be
sustainable or are indicative of future results.
 
     Service. Service revenues include fees from maintenance contracts,
training, training materials and consulting services. Fees for maintenance,
training, training materials and consulting services are generally charged
separately from the license of DecisionSuite. Maintenance fees are for ongoing
support and product updates, and are recognized ratably over the life of the
contract. Revenues from training are recognized upon completion of the related
training class. Revenues from training materials are recognized upon shipment or
upon provision of the materials to attendees of training classes. Consulting
revenues are recognized when the services are performed. Service revenues were
$3.0 million, $5.3 million and $11.9 million in fiscal 1996, 1997 and 1998,
respectively, representing increases of 77.8% from fiscal 1996 to fiscal 1997,
and 127.0% from fiscal 1997 to fiscal 1998. Service revenues increased 58.7%,
from $5.1 million to $8.2 million, between the six months ended July 31, 1997
and 1998. Service revenues accounted for 52.4%, 44.7% and 46.6% of IA's total
revenues in fiscal 1996, 1997 and 1998, and 50.7% and 42.8% for the six months
ended July 31, 1997 and 1998, respectively. In particular, maintenance revenues
accounted for 22.6%, 26.6% and 35.0% of service revenues in fiscal 1996, 1997
and 1998, and 25.7% and 29.6% of service revenues for the six months ended July
31, 1997 and 1998, respectively. IA anticipates that service revenues will
continue to account for a significant percentage of IA's total revenues and that
revenues from maintenance will increase as a percentage of service revenues as
additional licenses are sold.
 
     International Revenues. International revenues include all revenues other
than from the United States. International revenues from IA's direct sales
organizations in Europe and export sales to or through strategic partners in
Europe and other areas outside of the United States accounted for 10.7%, 9.5%,
and 9.7% of total revenues in fiscal 1996, 1997 and 1998, and 11.6% and 12.1%
for the six months ended July 31, 1997 and 1998, respectively. IA expects that
international license and related service revenues will continue to account for
a significant portion of its total revenues in the future.
 
COST OF REVENUES
 
     License. Cost of license revenues consists primarily of salaries,
royalties, product packaging and shipping. Cost of license revenues was
$118,000, $132,000 and $185,000 in fiscal 1996, 1997 and 1998, respectively,
representing 4.4%, 2.0% and 1.4% of license revenues for these years. Cost of
license revenues was $77,000 and $195,000 for the six months ended July 31, 1997
and 1998, respectively, representing 1.5% and 1.8% of license revenues for these
periods. The increase in cost of license revenues as a percentage of
 
                                       71
<PAGE>   85
 
license revenue between the six months ended July 31, 1997 and 1998 was
primarily due to royalties and increased personnel costs associated with the
packaging and shipping of product.
 
     Service. Cost of service revenues consists primarily of personnel-related
and facilities costs incurred in providing customer support, training and
consulting services, as well as third-party costs incurred in providing training
and consulting services. Cost of service revenues was $2.1 million, $3.3 million
and $7.5 million in fiscal 1996, 1997 and 1998, respectively, representing
72.0%, 62.9%, and 62.5% of service revenues for these years. Cost of service
revenues was $3.4 million and $4.1 million for the six months ended July 31,
1997 and 1998, respectively, representing 66.9% and 49.8% of service revenues
for these periods. The decrease in cost of service revenues as a percentage of
service revenues in fiscal 1996, 1997 and 1998, and for the six months ended
July 31, 1997 and 1998, was primarily due to increased productivity from a
significant number of newly hired training, support and consulting personnel,
and improved economies of scale of the technical support center.
 
OPERATING EXPENSES
 
     Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions and bonuses earned by sales and marketing personnel, field
office expenses, travel and entertainment and promotional expenses. Sales and
marketing expenses were $3.9 million, $11.4 million and $17.1 million in fiscal
1996, 1997 and 1998, and $7.8 million and $10.3 million for the six months ended
July 31, 1997 and 1998, respectively. The increase in sales and marketing
expenses was predominantly due to the hiring of additional sales and marketing
personnel and, to a lesser extent, the increase in the number of sales offices
and expanded promotional activities. Sales and marketing expenses represented
68.3%, 96.6% and 66.7% of total revenues in fiscal 1996, 1997 and 1998, and
77.1% and 53.9% of total revenues for the six months ended July 31, 1997 and
1998, respectively. The changes in sales and marketing expenses as a percentage
of total revenues were primarily due to the timing of hiring additional sales
personnel.
 
     IA expects that sales and marketing expenses will continue to increase as
IA continues to hire additional sales and marketing personnel, establish
additional sales offices and increase promotional activities.
 
     Research and Development. Research and development expenses consist
primarily of salaries and benefits of software engineering personnel, payments
to contract programmers and expendable equipment purchases. IA believes that a
significant level of investment for research and development is required to
remain competitive. Research and development expenses were $2.1 million, $3.2
million and $5.2 million in fiscal 1996, 1997 and 1998, and $2.4 million and
$2.9 million for the six months ended July 31, 1997 and 1998, respectively.
These increases were primarily attributable to additional hiring of research and
development personnel. Research and development expenses represented 37.0%,
27.2% and 20.4% of total revenues in fiscal 1996, 1997 and 1998, and 23.4% and
15.4% of total revenues for the six months ended July 31, 1997 and 1998,
respectively. IA anticipates that it will continue to devote substantial
resources to research and development and that these expenses will increase in
future periods.
 
     General and Administrative. General and administrative expenses were $1.2
million, $2.1 million and $2.1 million in fiscal 1996, 1997 and 1998, and $1.0
million and $1.3 million for the six months ended July 31, 1997 and 1998,
respectively. The increase was predominantly due to increased staffing and, to a
lesser extent, associated expenses necessary to manage and support IA's
increased scale of operations. General and administrative expenses represented
22.1%, 18.3% and 8.3% of total revenues in fiscal 1996, 1997 and 1998, and 10.2%
and 7.0% of total revenues for the six months ended July 31, 1997 and 1998,
respectively. IA believes that its general and administrative expenses will
increase in future periods as a result of an expansion of IA's administrative
staff to support its growing operations.
 
     Interest Income (Expense), Net. Interest income (expense), net, represents
interest earned by IA on its cash and short-term investments, offset by interest
expense on long-term debt and capitalized leases. See Notes 4 and 5 of Notes to
Consolidated Financial Statements.
 
     Provision for Income Taxes. IA accounts for income taxes in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes." IA has paid no federal or state income taxes
 
                                       72
<PAGE>   86
 
other than the required minimums in fiscal 1996, 1997 and 1998, or for the six
months ended July 31, 1997 and 1998. At July 31, 1998, IA had approximately
$20.5 million in federal net operating loss carryforwards. The federal net
operating loss carryforwards will begin to expire in the year 2007 if not
utilized. In addition, the Tax Reform Act of 1986 contains certain provisions
that may limit the net operating loss carryforwards available for use in any
given period upon the occurrence of certain events, including a significant
change in ownership interests.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" (SFAS No. 130). SFAS No. 130 is effective
for financial statements for fiscal years beginning after December 15, 1997.
This standard defines comprehensive income as the changes in equity of an
enterprise except those resulting from stockholder transactions. Management
believes the adoption of SFAS No. 130, effective February 1, 1998, has not had a
material effect on IA's financial statements.
 
     In June 1997, the Financial Accounting Standards Board also issued
Statement No. 131, "Disclosures about Segments of an Enterprise and Related
Information" (SFAS No. 131). SFAS No. 131 is effective for annual financial
statements for periods beginning after December 15, 1997. SFAS No. 131
establishes standards for disclosures about operating segments, products and
services, geographic areas and major customers. Management believes the adoption
of SFAS No. 131 will not have a material effect on IA's financial statements.

     IA's limited operating history and the susceptibility of IA's operating
results to significant fluctuations makes the prediction of future operating
results unreliable and IA believes that period-to-period comparisons of its
operating results are not necessarily meaningful and should not be relied upon
as indications of future performance. IA's operating results in any given period
can vary due to factors such as demand for IA's products, the size and
 
                                       74
<PAGE>   88
 
timing of significant orders and their fulfillment, the number, timing and
significance of product enhancements and new product announcements by IA and its
competitors, changes in pricing policies by IA or its competitors, customer
order deferrals in anticipation of enhancements or new products offered by IA or
its competitors, the ability of IA to develop, introduce and market new and
enhanced versions of its products on a timely basis, changes in IA's level of
operating expenses, budgeting cycles of its customers, product life cycles,
software defects and other product quality problems, hiring needs and personnel
changes, changes in IA's sales incentive plans, changes in the mix of domestic
and international revenues, the level of international expansion, foreign
currency exchange rate fluctuations, performance of indirect channel partners,
changes in the mix of indirect channels through which IA's products are offered,
the impact of acquisitions of competitors and indirect channel partners, IA's
ability to control costs and general domestic and international economic and
political conditions. A significant portion of IA's revenues has been, and IA
believes will continue to be, derived from a limited number of orders placed by
large organizations, and the timing of such orders and their fulfillment have
caused and are expected to continue to cause material fluctuations in IA's
operating results, particularly on a quarterly basis. A significant portion of
IA's revenues is derived from existing customers. To the extent that such
customers no longer require new licenses, or ongoing support, IA's business,
financial condition and operating results could be materially adversely
affected. IA has, from time to time, often recognized a substantial portion of
its revenues in the last month of a quarter, with these revenues frequently
concentrated in the last two weeks of a quarter. In addition, IA does not
operate with a large order backlog because its software products are typically
shipped shortly after orders are received, which makes product revenues in any
quarter substantially dependent on orders booked and shipped throughout that
quarter. Accordingly, revenues for any future quarter are difficult to predict.
IA also expects that as international sales increase as a percentage of sales it
will experience weaker demand for DecisionSuite during the summer months.
Product revenues are also difficult to forecast because the market for OLAP
applications is rapidly evolving, and IA's sales cycle, which may last from six
to twelve months or more, varies substantially from customer to customer. IA's
expense level and plans for expansion, including its plan to significantly
increase its research and development efforts, are based in significant part on
IA's expectations of future revenues and therefore are relatively fixed in the
short term. If revenue levels are below expectations, operating results are
likely to be adversely and disproportionately affected because only a small
portion of IA's expenses vary with its revenues. In addition, IA expects that
sales derived through indirect channels, which are more difficult to forecast
and generally have lower gross margins than direct sales, will increase as a
percentage of total revenues.
 
     Based upon all of the factors described above, IA believes that its
quarterly revenues, expenses and operating results are likely to vary
significantly in the future, that period-to-period comparisons of its operating
results are not necessarily meaningful and that, in any event, such comparisons
should not be relied upon as indications of future performance. Accordingly, IA
has limited ability to forecast future revenues, and it is likely that in some
future quarter IA's operating results will be below the expectations of public
market analysts and investors. In the event that operating results are below
expectations, or in the event that adverse conditions prevail or are perceived
to prevail generally or with respect to IA's business, the price of IA Common
Stock would be materially adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Operating activities
 
     Net cash used in operating activities was $3.6 million, $6.4 million and
$3.4 million in fiscal 1996, 1997 and 1998, respectively. For such periods, net
cash used in operating activities resulted primarily from net operating losses
and increases in prepaid expenses and accounts receivable associated with
increases in revenues, partially offset by increases in accounts payable,
accrued liabilities and deferred revenues.
 
     Net cash used in operating activities was $4.1 million and $2.6 million for
the six months ended July 31, 1997 and 1998, respectively. During the six months
ended July 31, 1997, cash used in operating activities resulted primarily from
net operating losses of $4.6 million and a $583,000 increase in accounts
receivable, partially offset by $524,000 noncash depreciation expense and a
$467,000 increase in accrued expenses.
 
     During the six months ended July 31, 1998, cash used in operating
activities included $2.5 million in additional accounts receivable and a $1.6
million increase in deferred revenue -- both associated with increases in
revenues. Also resulting in a use of cash was an increase of $788,000 in prepaid
expenses and other
 
                                       75
<PAGE>   89
 
current assets. These uses of cash were partially offset by $562,000 net income,
a $1.3 million increase in accrued expenses and $594,000 noncash depreciation
expense.
 
  Investing Activities
 
     Prior to fiscal 1999, IA's investing activities had consisted primarily of
purchases of property and equipment. Capital expenditures, including those under
capital leases, totaled $335,000, $1.1 million and $1.7 million in fiscal 1996,
1997 and 1998, respectively. Capital leases are used to acquire property and
equipment, primarily computer hardware, for IA's growing employee base. IA
expects that its capital expenditures will continue to increase as IA's employee
base grows.
 
     Net cash used in investing activities during the six months ended July 31,
1997 consisted of $222,000 in purchases of furniture and equipment. Net cash
used in investing activities during the six months ended July 31, 1998 of $10.2
million was composed of $12.4 million for the acquisition of short-term
investments and $730,000 in purchases of furniture and equipment, partially
offset by the maturities of $3.0 million in short-term investments.
 
  Financing Activities
 
     IA's financing activities provided $5.4 million, $6.0 million and $26.1
million in fiscal 1996, 1997 and 1998, respectively.
 
     In fiscal 1997, cash provided by financing activities was comprised
primarily of $4.9 million received in connection with the sale of Series C
Convertible Redeemable Preferred Stock and $1.5 million in proceeds from
long-term debt, offset by principal payments on long-term debt of $502,000. In
fiscal 1996, the cash provided by financing activities was comprised primarily
of $5.1 million received in connection with the sale of Series B Convertible
Redeemable Preferred Stock and $1.0 million in proceeds from notes issued to
stockholders, offset by repayments of notes payable to a bank of $435,000 and
principal payments on long-term debt of $217,000.
 
     In fiscal 1998, cash provided by financing activities was comprised
primarily of (i) an initial public offering of 3,834,100 shares (including an
overallotment of 500,100 shares) of IA Common Stock which generated net proceeds
of $19.8 million, (ii) proceeds from the sale of Series D Convertible Redeemable
Preferred Stock of $7.0 million, (iii) proceeds from the exercise of stock
options and stock purchase warrants of $1.1 million, and (iv) proceeds from
borrowings under lines of credit and long-term debt of $2.1 million, offset by
net reduction of debt under credit line borrowings and long-term borrowings of
$3.7 million.
 
     Net cash provided by financing activities during the six months ended July
31, 1997 of $6.6 million was generated principally by $6.9 million from the sale
of preferred stock, partially offset by $400,000 in principal payments on
capital leases. Net cash provided by financing activities during the six months
ended July 31, 1998 consisted of $404,000 in proceeds from the exercise of stock
options and purchase of shares of common stock under IA's employee stock
purchase plan, partially offset by $171,000 in principal payments on capital
leases.
 
  Commitments and Borrowing Capacity
 
     As of July 31, 1998, IA had no material commitments for capital
expenditures.
 
     IA has a revolving credit line of $2.0 million. There were no amounts
outstanding under this facility as of July 31, 1998.
 
     Total borrowings under the revolving credit line are limited generally to
the lesser of 70% of eligible accounts receivable or $2.0 million. IA's line of
credit contains certain financial covenants and restrictions as to various
matters including IA's ability to pay cash dividends and effect mergers or
acquisitions without the bank's prior approval. IA is currently in compliance
with such financial covenants and restrictions. IA has granted a first priority
security interest in substantially all of its assets as security for its
obligations under its
 
                                       76
<PAGE>   90
 
credit line which expires in September 1998. IA believes that, upon expiration,
this line will be renewed or replaced at similar or more favorable terms.
 
  Use of Proceeds from Initial Public Offering
 
     From the effective date of the Registration Statement on Form S-1 through
July 31, 1998, IA had used approximately $3.3 million of the net proceeds for
the repayment of indebtedness, and $730,000 for the purchase of furniture and
equipment.
 
     IA believes that the net balance of the proceeds from the December 1997
initial public offering and its existing cash, cash equivalents and short-term
investments will be adequate to meet its cash needs for at least the next 12
months. Thereafter, IA may require additional funds to support its working
capital requirements or for other purposes and may seek to raise such additional
funds through public or private equity financing or from other sources. There
can be no assurance that additional financing will be available at all or that,
if available, such financing will be obtainable on terms favorable to IA or will
not be dilutive.
 
YEAR 2000 COMPLIANCE
 
     IA is currently in the process of evaluating its information technology
infrastructure for Year 2000 compliance. IA plans to develop and implement its
Year 2000 compliance plan in fiscal 1999. IA does not expect the cost to modify
its information technology infrastructure to be Year 2000 compliant to be
material to its consolidated financial condition or results of operations
 
     IA uses outside vendors to supply its most significant data processing
software. These vendors have indicated their products are Year 2000 compliant or
will be Year 2000 compliant in the near future. IA does not currently have any
information concerning the Year 2000 compliance status of its key suppliers and
customers. In the event that any of IA's key suppliers or customers do not
successfully and timely achieve Year 2000 compliance, IA's business or
operations could be adversely affected. IA's Year 2000 compliance plan will
address the Year 2000 compliance status of key suppliers, customers and other
third parties.

DIRECTOR COMPENSATION
 
     Directors currently do not receive any cash compensation from IA for their
services as members of the IA Board, although members are reimbursed for certain
expenses in connection with attendance at the IA Board and Committee meetings.
Messrs. Hollis and Wein also serve as part-time consultants to IA for which they
have been compensated separately. Non-employee Board members are eligible for
option grants pursuant to the provisions of the Automatic Option Grant Program
under IA's 1997 Equity Incentive Plan (the "Plan"). Under the Automatic Option
Grant Program, each individual who first becomes a non-employee Board member
after December 16, 1997; will be granted an option to purchase 8,000 shares of
IA Common Stock on the date such individual joins the IA Board (the "Initial
Grant"). In addition, at each Annual Meeting of Stockholders, each individual
who will continue to serve as a member of the IA Board after such meeting will
receive an additional option to purchase 1,600 shares of IA Common Stock
("Annual Grant"). However, a director will not receive an Annual Grant in the
same calendar year that he received an Initial Grant. the exercise price for
each option granted under the Automatic Option Grant Program will be equal to
the fair market value per share of the Common Stock on the automatic grant date.
Each Initial Grant will become vested and exercisable with respect to 20% of the
option shares on the first anniversary of the date of grant and with respect to
an additional 1/60th of the option shares upon the completion of each month of
service thereafter. Each Annual Grant will become fully vested and exercisable
on the fifth anniversary of the date of grant.
 
     Directors who are also employees of IA are eligible to receive options and
be issued shares of IA Common Stock directly under IA's 1997 Equity Incentive
Plan and are also eligible to participate in IA's 1997 Employee Stock Purchase
Plan.

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
IA's officers, directors and persons who own more than ten percent of a
registered class of IA's equity securities to file reports of ownership and
changes in ownership with the SEC and to provide IA with copies of all such
reports. To IA's knowledge, based solely on a review of copies of reports filed
with the SEC during fiscal 1998, all applicable Section 16(a) filing
requirements were satisfied, except that one report on Form 4 setting forth the
acquisition of 4,000 shares of IA Common Stock by Ronald E.F. Codd on December
17, 1997 was not filed on a timely basis.

(1) Generally, 20% of these options vest on the first anniversary of the date of

    the date of grant occurring in 1999, 2000, 2001 and 2002. These options have
    a ten-year term, subject to earlier termination in the event of the
    optionee's cessation of service with IA.
 
(2) Based on an aggregate of 781,900 shares subject to options granted to
    employees of IA under the 1992 Stock Option Plan (the predecessor to the
    1997 Equity Incentive Plan).
 
(3) The exercise price may be paid in cash, in shares of IA Common Stock valued
    at fair market value on the exercise date or any other method approved by
    the IA Board.
 
(4) The potential realizable value is calculated based on the term of the option
    at the time of grant (ten years). Stock price appreciation of 5% and 10% is
    assumed pursuant to rules promulgated by the Commission and does not
    represent IA's prediction of its stock price performance. The potential
    realizable values at 5% and 10% appreciation are calculated by assuming that
    the exercise price on the date of grant appreciates at the indicated rate
    for the entire term of the option and that the option is exercised at the
    exercise price and sold on the last day of its term at the appreciated
    price.
 
OPTION VALUES
 
     The following table sets forth information concerning options to purchase
IA Common Stock exercised by the Named Executive Officers during fiscal year
1998 and the number and value of the unexercised options that are held by the

surviving entity in a capacity comparable to his then current position, 50% of
his unvested stock options or shares shall immediately vest; the remaining 50%

     In August 1997, IA granted Ronald E.F. Codd an option to purchase 8,000

Meeting of Stockholders. Such options are described further in "Executive
Compensation."
 
     IA has entered into employment agreements with Messrs. Ford, Tanler,
Anderson, Parker, Pederson and Terrien.
 
     In December 1997, IA and certain holders of its outstanding Preferred Stock
(the "Lenders") entered into a Loan and Warrant Purchase Agreement (the "Loan
Agreement") to provide IA with a source of funds for its working capital
requirements pending completion of its initial public offering. The Loan
Agreement provided IA with a revolving loan commitment of $3.0 million. The Loan
Agreement terminated ten days after the closing of its initial public offering.
IA did not draw down any funds under the Loan Agreement. In consideration of the
revolving loan commitment of the Lenders, IA issued warrants to the Lenders to
purchase an aggregate of 30,000 shares of IA Common Stock at a per share
purchase price of $5.00. Shares purchased upon exercise of the warrants are
entitled to certain registration rights.
 
     IA believes that all of the transactions set forth herein were made on
terms no less favorable to IA than could have been obtained from unaffiliated
third parties. All future transactions, including loans (if any), between IA and
its officers, directors, and principal stockholders and their affiliates will be
approved by a majority of the IA Board, including a majority of the independent
and disinterested Outside Directors, and will be on terms no less favorable to
IA than could be obtained from unaffiliated third parties.
 
INDEMNIFICATION
 
     IA's Certificate of Incorporation limits the liability of its directors for
monetary damages arising from a breach of their fiduciary duty as directors,
except to the extent otherwise required by the DGCL. Such limitation of
liability does not affect the availability of equitable remedies such as
injunctive relief or rescission.
 
     IA's Bylaws provide that IA shall indemnify its directors and officers to
the fullest extent permitted by Delaware law, including in circumstances in
which indemnification is otherwise discretionary under Delaware law. IA has
entered into indemnification agreements with its officers and directors
containing provisions that may require IA, among other things, to indemnify such
officers and directors against certain liabilities that may arise by reason of
their status or service as directors or officers (other than liabilities arising
from willful misconduct of a culpable nature), to advance their expenses
incurred as a result of any proceeding against them as to which they could be
indemnified, and to obtain directors' and officers' insurance if available on
reasonable terms.

                        DESCRIPTION OF IA CAPITAL STOCK
 
     The authorized capital stock of IA consists of 60,000,000 shares of Common
Stock, $0.01 par value, and 5,000,000 shares of Preferred Stock, $0.01 par
value.
 
COMMON STOCK
 
     As of August 14, 1998, there were 15,621,931 shares of IA Common Stock
outstanding that were held of record by approximately 175 stockholders. The
holders of IA Common Stock are entitled to one vote per share on all matters to
be voted upon by the stockholders. Subject to preferences that may be applicable
to any outstanding preferred stock, the holders of IA Common Stock are entitled
to receive ratably such dividends, if any, as may be declared from time to time
by the IA Board out of funds legally available therefor. In the event of the
liquidation, dissolution, or winding up of IA, the holders of IA Common Stock
are entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior distribution rights of preferred stock, if any,
then outstanding. The IA Common Stock has no preemptive or conversion rights or
other subscription rights. There are no redemption or sinking fund provisions
applicable to the IA Common Stock. All outstanding shares of IA Common Stock are
fully paid and nonassessable, and the shares of IA Common Stock to be issued in
connection with the Merger will be fully paid and nonassessable.
 
PREFERRED STOCK
 
     IA's Certificate of Incorporation authorizes 5,000,000 shares of preferred
stock, none of which are currently issued or outstanding. The IA Board has the
authority to issue the preferred stock in one or more series and to fix the
rights, preferences, privileges, and restrictions thereof, including dividend
rights, dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences, and the number of shares
constituting any series or the designation of such series, without further vote
or action by the stockholders. The issuance of preferred stock may have the
effect of delaying, deferring, or preventing a change in control of IA without
further action by the stockholders and may adversely affect the voting and other
rights of the holders of IA Common Stock. The issuance of preferred stock with
voting and conversion rights may adversely affect the voting power of the
holders of IA Common Stock, including the loss of voting control to others. IA
has no current plans to issue shares of preferred stock.
 
ANTITAKEOVER PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS AND DELAWARE
LAW
 
     IA's Certificate of Incorporation and Bylaws provide that the IA Board will
be divided into three classes of directors, with each class serving a staggered
three-year term. The classification system of electing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to
obtain control of IA and may maintain the incumbency of the IA Board, as the
classification of the IA Board generally increases the difficulty of replacing a
majority of the directors. IA's Certificate of Incorporation and Bylaws also
provide that all stockholder actions must be effected at a duly called meeting
and not by a consent in writing. IA's Certificate of Incorporation and Bylaws do
not permit stockholders of IA to call a special meeting of stockholders.
Further, provisions of IA's Certificate of Incorporation and Bylaws provide that
the stockholders may amend certain provisions of IA's Certificate of
Incorporation or Bylaws only with the affirmative vote of 80% of IA's capital
stock. These provisions of IA's Certificate of Incorporation and Bylaws could
discourage potential acquisition proposals and could delay or prevent a change
in control of IA. These provisions are intended to enhance the likelihood of
continuity and stability in the composition of the IA Board and in the policies
formulated by the IA Board and to discourage certain types of transactions that
may involve an actual or threatened changes in the management of the IA and may
have an adverse effect on the public trading price of IA Common Stock. See "Risk
Factors -- Effect of Certain Charter Provisions; Antitakeover Effects of
Certificate of Incorporation, Bylaws, and Delaware Law."
 
  Delaware Antitakeover Statute
 
     IA is subject to Section 203 of the DGCL ("Section 203"), which, subject to
certain exceptions, prohibits a Delaware corporation from engaging in any
business combination with any interested stockholder
 
                                       89
<PAGE>   103
 
for a period of three years following the date that such stockholder became an
interested stockholder, unless: (i) prior to such date, the board of directors
of the corporation approved either the business combination or the transaction
that resulted in the stockholder becoming an interested stockholder; (ii) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned (x) by persons who are directors and also
officers and (y) by employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer, or (iii) on or subsequent
to such date, the business combination is approved by the board of directors and
authorized at an annual or special meeting of stockholders, and not by written
consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
stock that is not owned by the interested stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge, or other disposition of 10% or more of the assets of the
corporation involving the interested stockholder; (iii) subject to certain
exceptions, any transaction that results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation that has the effect of increasing the
proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder; or (v) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees,
pledges, or other financial benefits provided by or through the corporation. In
general, Section 203 defines an interested stockholder as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
          COMPARISON OF RIGHTS OF IA STOCKHOLDERS AND IQ STOCKHOLDERS
 
     In connection with the Merger, IQ stockholders will be converting their
shares of IQ Common Stock into shares of IA Common Stock. IA is a Delaware
corporation and IQ is a Georgia corporation and the IA Certificate of
Incorporation (the "IA Certificate") and the IA Bylaws differ from the IQ
Articles of Incorporation (the "IQ Articles") and the IQ Bylaws (the "IQ
Bylaws") in several significant respects. Because of the differences between the
DGCL and the GCC, and the differences in the charter documents, the rights of a
holder of IQ Common Stock differ from the rights of a holder of IA Common Stock.
 
     Below is a summary of some of the important differences between the DGCL
and the GCC and the charter documents of IQ and IA. It is not practical to
summarize all of such differences in this Joint Proxy Statement/Prospectus, and
IQ and IA stockholders are referred to the DGCL, the GCC, and the IA Certificate
and Bylaws and the IQ Articles and Bylaws for more complete information
regarding the differences. Some of the principal differences could materially
affect the rights of stockholders, including the following:
 
POWER TO CALL SPECIAL STOCKHOLDERS' MEETINGS; ACTION BY WRITTEN CONSENT
 
     Under the GCC, a special meeting of stockholders may be called by the board
of directors, any person or persons authorized to do so by the articles of
incorporation or bylaws or by one or more stockholders holding 25% or more, or
such greater or lesser amount as may be provided in the articles or bylaws, of
the votes entitled to vote thereon. In addition, the IQ Articles provide that
any actions which may be taken at a meeting of stockholders may be taken without
a meeting if written consent setting forth the action so taken shall be signed
by persons who would be entitled to vote at a meeting of those shares holding
voting power to cast not less than the minimum number of votes that would be
necessary to authorize or take such actions at a meeting at which all shares
entitled to vote were present and voted.
 
     Under the DCGL, a special meeting of stockholders may be called by the
board of directors or by any other person authorized to do so in the
certification of incorporation or the bylaws. The IA Certificate and the IA
Bylaws provide that special meetings of stockholders may be called only by the
Chairman of the IA Board
 
                                       90
<PAGE>   104
 
or by a majority of the IA Board. The IA Certificate provides that any actions
taken by stockholders must be effected at an annual or special meeting and may
not be effected by written consent without a meeting.
 
BOARDS OF DIRECTORS
 
     The number of directors constituting the IQ Board is currently five. The
directors of IQ are divided into three classes, each class serving for a period
of three years. Approximately one-third of the members of the IQ Board are
elected by the stockholders annually. Vacancies and newly created directorships
may be filled solely by the vote of the remaining directors (even though less
than a quorum remains) provided that any vacancy occurring as a result of
removal of a director by the stockholders as permitted under the GCC and the IQ
Bylaws may only be filled by the stockholders. A member of the IQ Board may be
removed only for cause and only upon a vote of 66 2/3% of the outstanding shares
entitled to vote at a stockholder's meeting with respect to which notice of such
purpose was given.
 
     The number of directors constituting the IA Board is currently eight. The
IA Bylaws provide that the number of directors shall be fixed from time to time
exclusively pursuant to a resolution adopted by the majority of the IA Board,
but shall consist of not more than eleven or less than three directors. The
directors of IA are divided into three classes, each class serving for a period
of three years. Approximately one-third of the members of the IA Board are
elected by the stockholders annually. The DGCL provides that unless otherwise
provided in the certificate of incorporation, vacancies and newly created
directorships may be filled by a majority of the directors then in office
(although less than a quorum remains). The IA Certificate provides that
vacancies and newly created directorships may be filled solely by the vote of
the remaining directors (even though less than a quorum remains). The DGCL
provides that unless the certificate of incorporation provides otherwise, any
director or the entire board of directors may be removed, with or without cause,
by the holders of a majority of the shares then entitled to vote at an election
of directors. The IA Certificate provides that a member of the IA Board may be
removed from office at any time, but only for cause and only by the vote of the
holders of at least 80% of the voting power of the then outstanding voting
stock, voting together as a single class.
 
LIMITATION ON PERSONAL LIABILITY OF DIRECTORS
 
     Under the IQ Articles the IQ directors have no liability to IQ or its
stockholders for monetary damages for breach of duty of care or other duty as a
director to the fullest extent permitted by law; provided however, that
liability is not limited for appropriation, in violation of the director's
duties, of any business opportunity of IQ; for acts or omissions which involve
intentional misconduct or a knowing violation of the law; for certain unlawful
distributions under the GCC; and for any transaction from which the director
derived an improper personal benefit.
 
     Under the IA Certificate, no director will be personally liable to IA or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability for any breach of the directors duty of loyalty
to IA or its stockholders; for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law; for liability
arising out of certain unlawful dividends or stock repurchases or redemptions
under the DGCL; and for any transaction from which the director derived an
improper personal benefit.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Both the GCC and DGCL permit indemnification of directors and officers.
Under the GCC, a Georgia corporation may indemnify an individual who is a party
to a proceeding because he or she is or was a director, against liability
incurred in such proceeding, provided that such individual acted in good faith
and reasonably believed (a) in the case of conduct in his or her official
capacity, that such conduct was in the best interests of the corporation, (b) in
all other cases other than a criminal proceeding, that such conduct was at least
not opposed to the best interests of the corporation, and (c) in the case of a
criminal proceeding, that such individual had no reasonable cause to believe
that such conduct was unlawful. A Georgia corporation may not indemnify a
director under the GCC (i) in connection with a proceeding by or in the right of
the corporation,
 
                                       91
<PAGE>   105
 
except for reasonable expenses incurred by such director in connection with the
proceeding, provided it is determined that such director met the relevant
standard of conduct set forth above, or (ii) in connection with any proceeding
with respect to conduct for which such director was adjudged liable on the basis
that he or she received an improper personal benefit. Additionally, a Georgia
corporation may, before final disposition of a proceeding, advance funds to pay
for or reimburse the reasonable expenses incurred by a director who is a party
to a proceeding because he or she is a director, provided that such director
delivers to the corporation a written affirmation of his or her good faith
belief that he or she met the relevant standard of conduct or that the
proceeding involves conduct for which such director's liability has been
properly eliminated by action of the corporation, and a written undertaking by
the director to repay any funds advanced if it is ultimately determined that
such director was not entitled to such indemnification. Further, the GCC
requires a corporation to indemnify a director who was wholly successful in the
defense of a proceeding to which he or she was a party as a result of being a
director of the corporation for reasonable expenses.
 
     The GCC also allows a Georgia corporation to indemnify directors made a
party to a proceeding without regard to the above-referenced limitations, if
authorized by the articles of incorporation or a bylaw, contract, or resolution
duly adopted by a vote of the stockholders of the corporation by a majority of
votes entitled to be cast, excluding shares owned or voted under the control of
the director or directors who are not disinterested. Under the IQ Articles, IQ
shall indemnify a director against liability incurred in the proceeding and
shall advance and reimburse expenses incurred in the proceeding, including a
proceeding brought by or in the right of IQ, without regard to limitations
contained elsewhere in the GCC; provided, however, that IQ shall not indemnify a
director for any liability incurred in a proceeding in which the director is
adjudged liable to IQ or is subjected to injunctive relief in favor of IQ for
any appropriation, in violation of the director's duties, of any business
opportunity of IQ; for acts or omissions which involve intentional misconduct or
a knowing violation of the law; for certain unlawful distributions under the
GCC; and for any transaction from which the director derived an improper
personal benefit.
 
     Under the DGCL, a corporation may indemnify its directors, officers,
employees or agents, acting in their capacities as such, for expenses,
judgments, fines and settlement amounts actually and reasonably incurred by them
in connection with any action, suit or proceeding in which they acted in good
faith and in a manner they reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe their conduct was unlawful. In
addition, under the DGCL, with respect to any action by or in the right of the
corporation, a corporation may indemnify any of such persons against expenses
(including attorney's fees) actually and reasonably incurred by the person in
connection with the defense or settlement of such action or suit if the person
acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the court in which such action or suit was
brought shall determine that, despite the adjudication of liability but in view
of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.
Finally, under the DGCL, a corporation must indemnify a director or officer of a
corporation for expenses actually and reasonably incurred in connection with any
action, suit or proceeding as to which such person has been successful on the
merits or otherwise. The IA Bylaws provide that IA shall indemnify its directors
and officers to the fullest extent permitted by Delaware law, including in
circumstances in which indemnification is otherwise discretionary under Delaware
law.
 
VOTE ON EXTRAORDINARY CORPORATE TRANSACTIONS
 
     Delaware law provides that, unless otherwise specified in a corporation's
certificate of incorporation or unless the provisions of the DGCL discussed
below under "--Business Combination Restrictions" are applicable, a sale or
other disposition of all or substantially all of the corporation's assets, a
merger or consolidation of the corporation with another corporation or a
dissolution of the corporation requires the affirmative vote of the board of
directors (except in certain limited circumstances) plus, with certain
exceptions, the affirmative vote of a majority of the outstanding stock entitled
to vote thereon. The foregoing provisions apply to IA and its stockholders.
Georgia law is similar to Delaware law in that, except as described
 
                                       92
<PAGE>   106
 
below under "--Business Combination Restrictions," a sale or other disposition
of all or substantially all of the corporation's assets, a merger of the
corporation with or into another corporation, a share exchange involving one or
more classes or series of the corporation's shares or a dissolution of the
corporation must be adopted by the board of directors plus, with certain
exceptions, the affirmative vote of a majority of all shares of stock entitled
to vote thereon. Under the IQ Articles the affirmative vote of 66 2/3% of all
the votes entitled to be cast is necessary to approve and authorize any such
action required to be submitted to stockholders.
 
CERTAIN BUSINESS COMBINATIONS
 
     Both the GCC and DGCL include business combination statutes which are
generally designed to deter hostile takeovers by protecting minority
shareholders in the second stage of freeze-out mergers. Freeze-out mergers occur
when controlling stockholders prevent minority shareholders from receiving any
direct or indirect financial return from the corporation to persuade them to
liquidate their investment in the corporation on terms favorable to the
controlling stockholders. As defined under the GCC and DGCL, "business
combinations" encompass, among other types of combinations, a merger of a
corporation with any "interested stockholder" or a corporation associated or
affiliated with an "interested stockholder" who was an "interested stockholder"
prior to the transaction. Under Georgia Law, an "Interested Stockholder" is any
person who owns at least ten percent (10%) of the outstanding voting shares or
an affiliate of the corporation owning at least ten percent (10%) of the
outstanding voting shares within the prior two years. Under the GCC, certain
"business combinations" (including a merger, consolidation, asset transfer or
reclassification of equity securities) between a Georgia corporation and an
Interested Stockholder, are prohibited for five years from the time that such
Interested Stockholder becomes an Interested Stockholder unless (i) prior to
such time the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
Interested Stockholder; (ii) in the transaction which resulted in the
stockholder becoming an Interested Stockholder, the Interested Stockholder
became the beneficial owner of at least 90% of the corporation outstanding at
the time the transaction commenced, excluding shares owned by directors and
officers of the corporation, subsidiaries of the corporation, and certain
employee stock plans of the corporation; or (iii) subsequent to becoming an
Interested Stockholder such Interested Stockholder acquires additional shares
and thus becomes the beneficial owner of at least 90% of the outstanding voting
stock of the corporation, excluding shares owned by directors and officers of
the corporation, subsidiaries of the corporation, and certain employee stock
plans of the corporation.
 
     Furthermore, the GCC provides that a business combination must be either
(i) unanimously approved by the continuing directors provided that the
continuing directors constitute at least three members of the board of directors
at the time of such approval; or (ii) recommended by at least two-thirds of the
continuing directors and approved by a majority of the votes entitled to be cast
by holders of voting shares, other than voting shares beneficially owned by the
Interested Stockholder unless, among other conditions, the Georgia corporation's
common stockholders receive a minimum price (as defined in the GCC) for their
shares and the consideration is received in cash or in the same form as
previously paid by the Interested Stockholder for its shares. In general, a
Georgia corporation must specifically elect through its bylaws to be governed by
these provisions. However, because the IQ Bylaws do not currently explicitly
provide so, these GCC provisions do not apply to business combinations with
Interested Stockholders with respect to IQ.
 
     Delaware Law defines an "Interested Stockholder" as (i) any person who is
the direct or indirect beneficial owner of at least fifteen percent (15%) of the
voting power of any class or series of the then outstanding stock of the
corporation or (ii) an affiliate or associate of the corporation and within
three (3) years of the date in question was the direct or indirect owner of at
least fifteen percent (15%) of the voting power of any class or series of the
then outstanding stock of the corporation. Delaware Law prohibits a corporation
from engaging in any business combination with any Interested Stockholder for a
period of three (3) years following the date that such stockholder became an
Interested Stockholder unless (i) the board of directors approved either the
business combination or the transaction which resulted in the stockholder
becoming an Interested Stockholder; (ii) upon consummation of the transaction
which resulted in the stockholder becoming an Interested Stockholder, the
Interested Stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced; or (iii) sixty-six and
two-thirds
 
                                       93
<PAGE>   107
 
percent (66 2/3%) of the voting stock not beneficially owned by the Interested
Stockholder or any affiliate or associate of the Interested Stockholder is cast
in favor of the merger. In general, a Delaware corporation must specifically
elect, through an amendment to its bylaws or certificate of incorporation, not
to be governed by these provisions. IA has not made such an election and
therefore is currently subject to these provisions of the DGCL.
 
AUTHORIZED PREFERRED STOCK
 
     The IQ Board may authorize the issuance of shares of IQ preferred stock in
series, and by filing articles of amendment which are effective without
stockholder action to establish from time to time the number of shares to be
included in each such series, and to fix and determine the powers, preferences,
limitations and relative rights of the shares of each such series to the fullest
extent permitted under the GCC. The issuance of IQ preferred stock under certain
circumstances may have the effect of discouraging an attempt by a third party to
acquire control of IQ by, for example, authorizing the issuance of a series of
IQ preferred stock with the rights and preferences designed to impede the
proposed transaction, or by making it more difficult for a person who has gained
a substantial equity interest in IQ to obtain control or to exercise control
effectively.
 
     The IA Board may authorize the issuance of IA preferred stock at such
times, for such purposes and for such consideration as it may deem advisable
without further stockholder approval. The issuance of IA preferred stock under
certain circumstances may have the effect of discouraging an attempt by a third
party to acquire control of IA by, for example, authorizing the issuance of a
series of IA preferred stock with the rights and preferences designed to impede
the proposed transaction, or by making it more difficult for a person who has
gained a substantial equity interest in IA to obtain control or to exercise
control effectively.
 
AMENDMENTS TO THE IQ ARTICLES AND THE IA CERTIFICATE
 
     Under the GCC, significant amendments to a corporation's articles of
incorporation must be approved by the stockholders after being proposed by the
board of directors. Certain amendments to a corporation's articles of
incorporation may be adopted with approval of the board alone. The IQ Articles
additionally require approval of 66 2/3% of the outstanding shares entitled to
vote in order to amend certain provisions of the IQ Articles relating to
authorized capital, limitations on directors' liability, indemnification of
directors, consideration of certain constituencies other than stockholders in
making certain decisions, certain amendments to the IQ Articles and IQ Bylaws,
and approvals of certain mergers, share exchanges and sales of assets.
 
     Under the DGCL, a corporation's certificate of incorporation can be amended
by the affirmative vote of the board of directors and approved by the
affirmative vote of the holders of a majority of the outstanding shares entitled
to vote thereon, unless the certificate of incorporation requires the vote of a
larger portion of the shares. The IA Certificate requires approval of 80% of the
outstanding shares entitled to vote in order to amend certain provisions of the
IA Certificate relating to the power of the IA Board to establish a rights plan;
adoption, amendment or repeal of certain IA Bylaws; stockholders' rights to
inspect accounts and books of IA; and limitations on a director's personal
liability.
 
AMENDMENTS TO THE IQ BYLAWS AND THE IA BYLAWS
 
     Under the GCC, a corporation's bylaws may generally be amended or repealed
by the board of directors, subject to the power of the stockholders to amend or
repeal any such change to the bylaws. However, the IQ Articles reserve the power
to amend or repeal the IQ Bylaws or adopt new bylaws to the stockholders,
subject to the affirmative vote of 66 2/3% of all votes entitled to be cast, to
the extent such action would limit the provisions in the IQ Bylaws relating to
management of IQ by the IQ Board, the number and classification of directors,
vacancies on the IQ Board, or removal of directors of the IQ Board.
 
     Under DGCL and the IA Certificate and Bylaws, the IA Bylaws may be amended,
added to, rescinded or repealed at any meeting of the IA Board or of
stockholders where adequate notice was given of such meetings; provided,
however, that the affirmative vote of the holders of at least 80% of the voting
power of the then outstanding shares shall be required to alter, amend or repeal
those sections of the IA Bylaws regarding special meetings of stockholders; the
establishment of a quorum of stockholders at a stockholders' meeting; voting
 
                                       94
<PAGE>   108
 
rights of stockholders; notice of stockholder business and nominations; the
prohibition against stockholder action by written consent; the number, tenure
and qualifications of directors; director vacancies and newly created
directorships; meetings of the IA Board; and the amendment and repeal of certain
bylaws.
 
RIGHTS PLAN
 
     The IA Certificate expressly authorizes the IA Board to create and issue
rights entitling the holders thereof to purchase from IA shares of stock or
other securities of IA. The IA Certificate recognizes that under certain
circumstances, the creation and issuance of such rights could have the effect of
discouraging third parties from seeking or impairing their ability to seek, to
acquire a significant portion of the outstanding securities of IA, to engage in
any transaction which might result in a change of control of IA or to enter into
any agreement, arrangement or understanding with another party to accomplish the
foregoing or for the purpose of acquiring, holding, voting of disposing of any
securities of IA. The times at which and terms upon which such rights are to be
issued will be determined by the IA Board. While the IA Board has not undertaken
to create or issue any rights, such Rights if adopted and issued could have
certain anti-takeover effects.
 
     The IQ Articles contains no such explicit authorization; however the IQ
Board could adopt a rights plan if it determined such a plan were in the best
interests of IQ and its stockholders.
 
                                 LEGAL MATTERS
 
     Certain legal matters in connection with the IA Common Stock to be issued
in connection with the Merger and certain tax consequences of the Merger will be
passed upon for IA by Gunderson Dettmer Stough Villeneuve Franklin & Hachigian,
LLP, Menlo Park, CA. Certain tax consequences of the Merger will be passed upon
for IQ by Miller & Martin LLP, Atlanta, GA. A partner of Miller & Martin LLP
beneficially owns 27,261 shares of IQ Common Stock.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF
INFORMATION ADVANTAGE, INC.
 
     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of stockholders' equity (deficit) and of
cash flows present fairly, in all material respects, the financial position of
Information Advantage, Inc. and its subsidiaries at January 31, 1997 and 1998,
and the results of their operations and their cash flows for each of the three
years in the period ended January 31, 1998, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

NOTE 1. ORGANIZATION AND INITIAL PUBLIC OFFERING
 
     Information Advantage, Inc. ("IA") develops, markets and supports
enterprise scalable on-line analytical processing software that is designed to
allow large numbers of users to access and analyze large amounts of data to make
quick and more informed business decisions. IA's relational server-based
solution, DecisionSuite, provides powerful, robust and flexible analysis
processing capabilities that transform raw data into meaningful information from
a wide range of desktop and Internet platforms. IA also provides a comprehensive
range of related training, consulting and customer support services.
 
     In December 1997, IA completed an initial public offering of its common
stock, which generated $19.8 million net proceeds. A portion of the net proceeds
was used to repay in full IA's lines of credit and subordinated debt. In
addition, concurrent with the offering, IA's convertible preferred stock and
substantially all stock purchase warrants were converted to common stock.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
     The consolidated financial statements include accounts of IA and
wholly-owned subsidiaries operating in the United Kingdom and Germany. All
significant intercompany accounts and transactions have been eliminated.
 
REVERSE STOCK SPLIT
 
     On October 8, 1997, the IA Board approved a reverse 1-for-2 1/2 stock split
which became effective on December 3, 1997. The effect of the reverse stock
split has been reflected for all periods presented in the accompanying financial
statements.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
FOREIGN CURRENCY TRANSLATION
 
     All assets and liabilities of IA's foreign subsidiaries are translated from
local currencies to U.S. dollars at period end rates of exchange, while the
consolidated statement of operations is translated at the average exchange rates
during the period. The functional currency for IA's United Kingdom and German
subsidiaries is the respective local currencies. Translation adjustments arising
from the translation of net assets located outside of the United States into
U.S. dollars are recorded as a separate component of stockholders' equity.
Transaction gains or losses on sales to foreign customers which are denominated
in their local currencies are recorded in the statement of operations. IA has
not experienced any material transaction gains or losses.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     Cash and cash equivalents consist of cash, money market instruments and
United States Government Treasury Bills having original maturities less than 90
days. Cash and money market instruments are stated at their fair values.
Treasury Bills are considered "held-to-maturity" and are stated at their
amortized cost which approximates fair value. The fair value of all other
financial instruments approximates cost as stated.

REVENUE RECOGNITION AND SIGNIFICANT CUSTOMERS
 
     Revenues derived from software licenses are recognized upon (a) the
execution of a license agreement, (b) delivery of the software product (c)
reasonable assurance of customer acceptance of the software and collectibility
of the receivable, and (d) fulfillment of any other of IA's contract
obligations. For software provided for demonstration or pilot purposes, or where
significant post-delivery obligations exist, revenues are deferred until
execution of a license agreement and fulfillment of all revenue recognition
requirements. Revenues derived from maintenance contracts which are bundled with
the initial licenses and all revenues from extended maintenance contracts are
deferred and recognized ratably over the term of the maintenance contract.
Revenues from maintenance contracts are included in services revenues. Revenues
from training and consulting services are recognized as the services are
performed. IA's policy is in compliance with the provisions of the American
Institute of Certified Public Accountants' Statement of Position 91-1, "Software
Revenue Recognition."
 
     Financial instruments which potentially subject IA to credit risk consist
primarily of accounts receivable. IA grants credit to customers in the ordinary
course of business. Different individual customers accounted for approximately
14%, 10% and 6% of revenues during 1996, 1997 and 1998, respectively. As of
January 31, 1998, a single customer accounted for 18% of total accounts
receivable.
 
     Accounts receivable are stated net of the related allowance for doubtful
accounts of $101 and $201 as of January 31, 1997 and 1998, respectively.
 
RESEARCH AND DEVELOPMENT
 
     Expenditures for research and software development are expensed as
incurred. Such costs are required to be expensed until the point that
technological feasibility of the product is established and the realizability of
any capitalized costs is determined. Technological feasibility is evidenced by a
working model. The period between achieving technological feasibility and the
general availability to the public of such software has been short.
Consequently, costs otherwise capitalizable after technological feasibility is
achieved have been expensed because they have been insignificant to both total
assets and net loss.
 
FURNITURE AND EQUIPMENT
 
     Furniture and equipment, including those assets acquired under capital
leases, consists of computers and office equipment, and is depreciated using the
straight-line method over the estimated useful lives of the assets, which
generally range from 3 to 5 years. Significant additions or improvements
extending asset lives are capitalized, while repairs and maintenance are charged
to expense as incurred. Amortization of assets under capital leases is included
in depreciation expense. The amount of leased equipment consists of the
following:

INCOME TAXES
 
     Income taxes are accounted for on the liability method in accordance with
Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for
Income Taxes." Under the liability method, deferred tax assets and liabilities
are determined based on the difference between the financial statement and tax
bases of assets and liabilities reduced by a valuation allowance, as necessary.
 
EARNINGS PER SHARE
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share" (SFAS No. 128). SFAS No. 128 applies to entities
with publicly held common stock and is effective for financial statements issued
for periods ending after December 15, 1997. Under SFAS No. 128 the presentation
of primary earnings per share is replaced with a presentation of basic earnings
per share. SFAS No. 128 requires dual presentation of basic and diluted earnings
per share for entities with complex capital structures. Basic earnings per share
includes no dilution and is computed by dividing net income (loss) available to
common stockholders by the weighted average number of common shares outstanding
for the period. Diluted earnings per share reflects the potential dilution of
securities that could share in the earnings of an entity, similar to fully
diluted earnings per share. To date, IA has incurred net losses, thus there has
been no impact from common stock warrants and options on weighted average shares
outstanding. Should earnings be generated in future years, the impact of
warrants and options would be dilutive to earnings per share. All earnings per
share amounts for all periods have been presented or restated to conform with
the provisions of SFAS No. 128.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" (SFAS No. 130). SFAS No. 130 is effective
for financial statements for fiscal years beginning after December 15, 1997.
This standard defines comprehensive income as the changes in equity of an
enterprise except those resulting from stockholder transactions. All components
of comprehensive income are required to be reported in a new financial
statement. Management believes the adoption of SFAS No. 130 will not have a
material effect on IA's financial statements.
 
     In June 1997, the Financial Accounting Standards Board also issued
Statement No. 131, "Disclosures about Segments of an Enterprise and Related
Information" (SFAS No. 131). SFAS No. 131 is effective for financial statements
for periods beginning after December 15, 1997. SFAS No. 131 establishes
standards for disclosures about operating segments, products and services,
geographic areas and major customers. Management believes the adoption of SFAS
No. 131 will not have a material effect on IA's financial statements.
 
     The American Institute of Certified Public Accountants' has approved a new
Statement of Position (SOP), SOP 97-2, effective for transactions entered into
after December 15, 1997, which will supersede Statement of Position 91-1,
"Software Revenue Recognition." Management has assessed this new statement and
believes that its adoption will not have a material effect on the timing of IA's
revenue recognition or cause changes to its revenue recognition policies.

NOTE 4. LINES OF CREDIT
 
     IA has a $2.0 million working capital line of credit with a bank which
expires September 2, 1998. Borrowings are limited to the lesser of $2.0 million
or 70% of eligible accounts receivable. Borrowings bear interest at an annual
rate of 1.75% above the bank's prime rate (8.5% at January 31, 1998) and are
collateralized by all of IA's assets. No amounts were outstanding under the line
as of January 31, 1997 or 1998. Maximum and average borrowings during fiscal
1998 were $1,715 and $298, respectively. There were no borrowings in fiscal
1997.
 
     Management believes that, upon the September 2, 1998 expiration of the line
of credit, the agreement will be renewed or replaced at similar or more
favorable terms. The line of credit agreement contains certain covenants
pertaining to operating results and certain other financial ratios. IA is
currently in compliance with these covenants.
 
     IA also maintained with a bank a $400 equipment line of credit, which was
collateralized by specific, related assets. The line bore interest at 1.75% over
the bank's prime rate (8.5% at January 31, 1998). During October 1997, IA
borrowed $400 under the line, which was repaid in full and expired in December
1997.

NOTE 7. INCOME TAXES
 
     At January 31, 1998, IA had net operating loss carryforwards of
approximately $21 million for income tax purposes. The net operating loss
carryforwards will begin to expire in 2007. Utilization of these net operating
loss carryforwards in the future by IA may be limited or deferred subject to
Section 382 of the Internal Revenue Code. No future tax benefit for such
carryforwards or other temporary differences has been recognized since
utilization of such benefits is not presently deemed by management to be more
likely than not based on the weight of available evidence.
 
     Deferred income taxes reflect the tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
IA's deferred tax liabilities and assets are as follows:

NOTE 8. CAPITAL STRUCTURE
 
     In prior years, IA had the following authorized capital stock: 60,000,000
common shares, 4,000,000 Series A convertible redeemable preferred shares,
4,000,000 Series B convertible redeemable preferred shares, 1,633,198 Series C
convertible redeemable preferred shares, 1,400,000 Series D convertible
redeemable preferred shares, 4,000,000 Series E convertible redeemable preferred
shares, 4,000,000 Series F convertible redeemable preferred shares, 1,633,198
Series G convertible redeemable preferred shares, and 1,400,000 Series H
convertible redeemable preferred shares (collectively, the Preferred Shares),
all of which had $0.01 par value. The Preferred Shares were converted upon the
closing of the initial public offering of IA Common Stock.
 
     In September 1997, the IA Board increased the authorized shares of IA and
designated a par value of $0.01 for common and convertible redeemable preferred
shares. All applicable share data included in the financial statements has been
adjusted to give retroactive effect to such action. In addition, IA authorized
5,000,000, $.01 par value preferred shares which became effective subsequent to
the closing of the initial public offering.
 
WARRANTS
 
     In December 1997, IA and certain holders of its outstanding preferred stock
(the "Lenders") entered into an agreement (the "Loan Agreement") to provide IA
with a $3 million revolving loan commitment. In conjunction with the Loan
Agreement, which expired, unused, 10 days following the closing of the offering,
IA

granted to the Lenders warrants to purchase a total of 30,000 shares of IA
Common Stock at a purchase price of $5.00 per share. Such warrants expire
December 2002. Using the fair value method prescribed in SFAS No. 123, the fair
value of the warrants was immaterial.
 
     Immediately prior to the offering, IA had outstanding 779,826 stock
purchase warrants at conversion prices ranging from $1.50 to $5.00. Of these,
606,407 warrants were automatically exercised and converted into 429,565 shares
of IA Common Stock upon the closing of the offering.
 
NOTE 9. STOCK OPTION AND EMPLOYEE STOCK PURCHASE PLANS
 
STOCK OPTION PLANS
 
     IA has a stock incentive plan (the "1992 Stock Option Plan") that reserves
a total of 2,640,000 shares of common stock for issuance of stock options to
employees, officers and directors.
 
     In September 1997, the IA Board adopted the 1997 Equity Incentive Plan (the
"1997 Plan"). The number of shares of IA Common Stock reserved for issuance
under the 1997 Plan is equal to 1,000,000, plus the number of remaining shares
available for grant under IA's 1992 Stock Option Plan at the effective date of
the offering. Beginning February 1, 1999 and each year thereafter, the number of
shares reserved for issuance will automatically increase by the lesser of
400,000 shares or 3.5% of the total number of shares of IA Common Stock then
outstanding.
 
     The option price for stock options granted is determined by the IA Board on
the date of grant. Canceled options are available for future grant and unvested
options issued to employees are canceled when their employment with IA
terminates. Generally, options granted to employees vest over a five-year period
and expire ten years after the date of grant.
 
     IA records compensation related to stock options using the intrinsic value
method of APB No. 25. Compensation related to stock options granted below fair
market value through January 31, 1998 approximates $1.1 million. Such
compensation is considered deferred compensation and amortized over the vesting
period of the related options.
 
     IA has adopted the disclosure-only provisions of SFAS No. 123. For purposes
of the pro forma disclosures below, the estimated fair value of the options is
amortized to expense over the options' vesting period. Had compensation cost for
IA's stock plan been determined based on the minimum value at the grant date for
awards during fiscal 1996, 1997 and 1998 consistent with the provisions of SFAS
No. 123, IA's net losses would have been increased to the pro forma amounts
indicated below:

     The minimum value of each option grant is estimated on the date of grant
using the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in fiscal 1997 and 1998, respectively; dividend
yield of 0%; risk-free interest rates of 6.4% and 6.2%; and expected lives of
8.5 years. Volatility factors are not applicable to non-public companies.

 1. BASIS OF PRESENTATION
 
     The financial information furnished is unaudited except for the balance
sheet as of January 31, 1998. The unaudited consolidated financial statements as
of and for the three and six months ended July 31, 1997 and 1998 have been
prepared on the same basis as the audited consolidated financial statements for
the year ended January 31, 1998, and include all adjustments, consisting only of
normal recurring accruals, which in the opinion of management are necessary for
the fair presentation of such information for the periods presented.
 
     Certain notes normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted.
These financial statements should be read in conjunction with IA's audited
financial statements and notes thereto for the three years ended January 31,
1998, included in IA's annual report on Form 10-K. In addition, the results of
operations for the interim periods presented may not be indicative of results
for the entire year.
 
 2. NEW ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" (SFAS No. 130). SFAS No. 130 is effective
for financial statements for fiscal years beginning after December 15, 1997.
This standard defines comprehensive income as the changes in equity of an
enterprise except those resulting from stockholder transactions. The adoption of
SFAS No. 130, effective February 1, 1998, did not have a material effect on IA's
financial statements. For IA, only cumulative translation adjustments are
included in accumulated other comprehensive income.
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
131, "Disclosures about Segments of an Enterprise and Related Information" (SFAS
No. 131). SFAS No. 131 is effective for annual financial statements for periods
beginning after December 15, 1997. SFAS No. 131 establishes standards for
disclosures about operating segments, products and services, geographic areas
and major customers. IA will adopt SFAS No. 131 effective for its annual report
for the fiscal year ending January 31, 1999. Management believes the adoption of
SFAS No. 131 will not have a material effect on IA's financial statements.
 
     The American Institute of Certified Public Accountants has approved
Statement of Position (SOP), SOP 97-2, effective for transactions entered into
after December 15, 1997, which supersedes Statement of Position 91-1, "Software
Revenue Recognition." Management has adopted this new statement and has
determined that its adoption has not had a material effect on the timing of IA's
revenue recognition or caused changes to its revenue recognition policies.
 
 3. SHORT-TERM INVESTMENTS
 
     Short-term investments consist of United States Government Treasury Bills
having original maturities greater than 90 days. Treasury Bills are considered
"held-to-maturity" and are stated at their amortized cost which approximates
fair value.

                          AGREEMENT AND PLAN OF MERGER
 
     This AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER (this "Agreement"),
dated as of June 29, 1998, is by and among Information Advantage, Inc., a
Delaware corporation ("Parent"), IQ Software Corporation, a Georgia corporation
(the "Company"), and IAC Merger Corp., a Georgia corporation and a direct,
wholly owned subsidiary of Parent ("Merger Sub").
 
     WHEREAS, the Boards of Directors of the Company and Parent deem it
advisable and in the best interests of each corporation and its respective
stockholders that the Company and Parent combine in order to advance the
long-term business interests of the Company and Parent;
 
     WHEREAS, the Company, Merger Sub and Parent intend to effect a merger (the
"Merger") of Merger Sub with and into the Company in accordance with this
Agreement and the Georgia Business Corporation Code (the "GCC");
 
     WHEREAS, upon the closing of the Merger, Merger Sub will cease to exist and
the Company will become a wholly owned subsidiary of Parent (the Company, from
and after the Merger, is sometimes referred to herein as the "Surviving
Corporation");
 
     WHEREAS, concurrently with the execution and delivery of this Agreement and
as a condition and inducement to Parent to enter into this Agreement, Parent and
the Company have entered into a Stock Option Agreement dated as of the date of
this Agreement and attached hereto as Exhibit A (the "Stock Option Agreement"),
pursuant to which the Company granted Parent an option to purchase shares of
common stock of the Company under certain circumstances;
 
     WHEREAS, for Federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"); and
 
     WHEREAS, for accounting purposes, it is intended that the Merger shall be
accounted for as a pooling of interests;
 
     WHEREAS, on July 24, 1998 the parties agreed to make certain technical
amendments to this Agreement to correct factual errors in this Agreement; to
restate this Agreement to reflect such changes; and further agreed such amended
and restated agreement would be effective as of June 29, 1998.
 
     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
parties agree as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     1.1  Effective Time of the Merger. Subject to the provisions of this
Agreement, a certificate of merger in such form as is required by the relevant
provisions of the GCC (the "Certificate of Merger") shall be duly prepared,
executed and acknowledged by the Surviving Corporation and thereafter delivered
to the Secretary of State of the State of Georgia, for filing, as provided in
the GCC, as soon as practicable on or after the Closing Date (as defined in
Section 1.2). The Merger shall become effective upon the filing of the
Certificate of Merger with the Secretary of State of the State of Georgia or at
such time thereafter as is provided in the Certificate of Merger (the "Effective
Time").
 
     1.2  Closing. The closing of the Merger (the "Closing") will take place at
10:00 a.m., local time, on a date to be specified by the Company and Parent,
which shall be no later than the second business day after satisfaction of the
latest to occur of the conditions set forth in Sections 8.1, 8.2 and 8.3 (the
"Closing Date"), at the offices of Gunderson Dettmer Stough Villeneuve Franklin
& Hachigian, LLP, 155 Constitution Drive, Menlo Park, California, unless another
date, place or time is agreed to in writing by the Company and Parent.

<PAGE>   135
 
     1.3  Effects of the Merger. At the Effective Time (i) the separate
existence of Merger Sub shall cease and Merger Sub shall be merged with and into
the Company (Merger Sub and the Company are sometimes referred to together as
the "Constituent Corporations"), (ii) the Bylaws of Merger Sub as in effect
immediately prior to the Effective Time shall be the Bylaws of the Surviving
Corporation, (iii) the directors and officers of the Surviving Corporation
immediately after the Merger shall be as determined by the Board of Directors of
the Parent and shall serve until their respective successors are elected and
qualified or duly appointed, as the case may be, (iv) all the property, rights,
privileges, powers and franchises and duties of Merger Sub and the Company shall
vest in the Surviving Corporation, and (v) all debts, liabilities and duties of
the Company and Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.
 
     1.4  Director of the Company. At the Effective Time, Parent shall cause
Charles R. Chitty to be named as member of the Board of Directors of Parent;
provided, that if such person is unwilling or unable to serve in such capacity,
his replacement, if any, shall be selected by Parent's Board of Directors as
constituted at the Effective Time.

                            CONVERSION OF SECURITIES
 
     2.1  Conversion of Capital Stock. As of the Effective Time, by virtue of
the Merger and without any action on the part of the holder of any shares of
Company Common Stock or the capital stock of Merger
Sub:
 
          (a) Capital Stock of Merger Sub. Each issued and outstanding share of
     the capital stock of Merger Sub shall be converted into and become one
     fully paid and nonassessable share of Common Stock of the Surviving
     Corporation.
 
          (b) Cancellation of Treasury Stock and Parent-Owned Stock. All shares
     of Common Stock of the Company, par value .00033 per share ("Company Common
     Stock"), that are owned by Company or any Subsidiary (as defined in Section
     3.1) of the Company shall be canceled and retired and shall cease to exist
     and no stock of Parent or other consideration shall be delivered in
     exchange therefor. All shares of Company Common Stock owned by Parent shall
     be unaffected by the Merger.
 
          (c) Exchange Ratio for Company Common Stock. Subject to Section 2.2,
     each issued and outstanding share of Company Common Stock (other than
     shares to be canceled in accordance with Section 2.1(b)) shall be converted
     into the right to receive 1.96 shares (the "Exchange Ratio") of Common
     Stock, $.01 par value, of Parent ("Parent Common Stock"). All such shares
     of Company Common Stock, when so converted, shall no longer be outstanding
     and shall automatically be canceled and retired and shall cease to exist,
     and each holder of a certificate representing any such shares shall cease
     to have any rights with respect thereto, except the right to receive the
     shares of Parent Common Stock and any cash in lieu of fractional shares of
     Parent Common Stock to be issued or paid in consideration therefor upon the
     surrender of such certificate in accordance with Section 2.2, without
     interest.
 
          (d) Adjustments to Exchange Ratio. The Exchange Ratio shall be
     adjusted to reflect fully the effect of any stock split, reverse split,
     stock dividend (including any dividend or distribution of securities
     convertible into Parent Common Stock or Company Common Stock),
     reorganization, recapitalization or other like change with respect to
     Parent Common Stock or Company Common Stock occurring after the date hereof
     and prior to the Effective Time.
 
     2.2  Exchange of Certificates. The procedures for exchanging outstanding
shares of Company Common Stock for Parent Common Stock pursuant to the Merger
are as follows:
 
          (a) Exchange Agent. As of the Effective Time, Parent shall deposit
     with a bank or trust company designated by Parent (the "Exchange Agent"),
     for the benefit of the holders of shares of the Company Common Stock, for
     exchange in accordance with this Section 2.2, through the Exchange Agent,
     (i) certificates representing the shares of Parent Common Stock (such
     shares of Parent Common Stock,
 
                                       A-2
<PAGE>   136
 
     together with any dividends or distributions with respect thereto, being
     hereinafter referred to as the "Exchange Fund") issuable pursuant to
     Section 2.1 in exchange for outstanding shares of Company Common Stock, and
     (ii) cash in an amount sufficient to permit payment of cash in lieu of
     fractional shares pursuant to Section 2.2(e).
 
          (b) Exchange Procedures. As soon as reasonably practicable after the
     Effective Time, but not later than ten business days thereafter, the
     Exchange Agent shall mail to each holder of record of a certificate or
     certificates which immediately prior to the Effective Time represented
     outstanding shares of Company Common Stock (the "Certificates") whose
     shares were converted pursuant to Section 2.1 into the right to receive
     shares of Parent Common Stock (i) a letter of transmittal (which shall
     specify that delivery shall be effected, and risk of loss and title to the
     Certificates shall pass, only upon delivery of the Certificates to the
     Exchange Agent and shall be in such form and have such other provisions as
     the Company and Parent may reasonably specify) and (ii) instructions for
     effecting the surrender of the Certificates in exchange for certificates
     representing shares of Parent Common Stock (plus cash in lieu of fractional
     shares, if any, of Parent Common Stock as provided in Section 2.2(e)
     below). Upon surrender of a Certificate for cancellation to the Exchange
     Agent or to such other agent or agents as may be appointed by Parent,
     together with such letter of transmittal, duly executed, the holder of such
     Certificate shall be entitled to receive in exchange therefor a certificate
     representing that number of whole shares of Parent Common Stock which such
     holder has the right to receive pursuant to the provisions of this Article
     II and payment in lieu of fractional shares which the holder of such
     Certificate has the right to receive pursuant to Section 2.2(e), and the
     Certificate so surrendered shall immediately be canceled. In the event of a
     transfer of ownership of Company Common Stock which is not registered in
     the transfer records of the Company, a certificate representing the proper
     number of shares of Parent Common Stock may be issued to a transferee if
     the Certificate representing such the Company Common Stock is presented to
     the Exchange Agent, accompanied by all documents required to evidence and
     effect such transfer and by evidence that any applicable stock transfer or
     other applicable taxes have been paid. Until surrendered as contemplated by
     this Section 2.2, each Certificate shall be deemed at any time after the
     Effective Time to represent only the right to receive upon such surrender
     the certificate representing shares of Parent Common Stock and cash in lieu
     of any fractional shares of Parent Common Stock as contemplated by this
     Section 2.2.
 
          (c) Distributions with Respect to Unexchanged Shares. No dividends or
     other distributions declared or made after the Effective Time with respect
     to Parent Common Stock with a record date after the Effective Time shall be
     paid to the holder of any unsurrendered Certificate with respect to the
     shares of Parent Common Stock represented thereby and no cash payment in
     lieu of fractional shares shall be paid to any such holder pursuant to
     Section 2.2(e) below until the holder of record of such Certificate shall
     surrender such Certificate. Subject to the effect of applicable laws,
     following surrender of any such Certificate, there shall be paid to the
     record holder of the certificates representing whole shares of Parent
     Common Stock issued in exchange therefor, without interest, (i) at the time
     of such surrender, the amount of any cash payable in lieu of a fractional
     share of Parent Common Stock to which such holder is entitled pursuant to
     Section 2.2(e) below and the amount of dividends or other distributions
     with a record date after the Effective Time previously paid with respect to
     such whole shares of Parent Common Stock, and (ii) at the appropriate
     payment date, the amount of dividends or other distributions with a record
     date after the Effective Time but prior to surrender and a payment date
     subsequent to surrender payable with respect to such whole shares of Parent
     Common Stock.
 
          (d) No Further Ownership Rights in Company Common Stock. All shares of
     Parent Common Stock issued upon the surrender for exchange of Certificates
     in accordance with the terms hereof (including any cash paid pursuant to
     subsection (c) or (e) of this Section 2.2) shall be deemed to have been
     issued in full satisfaction of all rights pertaining to such shares of
     Company Common Stock, subject, however, to the Surviving Corporation's
     obligation to pay any dividends or make any other distributions with a
     record date prior to the Effective Time which may have been declared or
     made by the Company on such shares of Company Common Stock in accordance
     with the terms of this Agreement (to the extent permitted under Section
     5.2) prior to the date hereof and which remain unpaid at the Effective
     Time, and
 
                                       A-3
<PAGE>   137
 
     from and after the Effective Time there shall be no further registration of
     transfers on the stock transfer books of the Surviving Corporation of the
     shares of Company Common Stock which were outstanding immediately prior to
     the Effective Time. If, after the Effective Time, Certificates are
     presented to the Surviving Corporation for any reason, they shall be
     canceled and exchanged as provided in this Section 2.2.
 
          (e) No Fractional Shares. No certificate or scrip representing
     fractional shares of Parent Common Stock shall be issued upon the surrender
     for exchange of Certificates, and such fractional share interests will not
     entitle the owner thereof to vote or to exercise any other rights of a
     stockholder of Parent. Notwithstanding any other provision of this
     Agreement, each holder of shares of Company Common Stock exchanged pursuant
     to the Merger who would otherwise have been entitled to receive a fraction
     of a share of Parent Common Stock (after taking into account all
     Certificates delivered by such holder) shall receive, in lieu thereof, cash
     (without interest) in an amount equal to such fractional part of a share of
     Parent Common Stock multiplied by the average of the last reported sales
     prices of Parent Common Stock, as reported on the Nasdaq National Market,
     on each of the ten trading days immediately preceding the Closing Date.
 
          (f) Termination of Exchange Fund. Any portion of the Exchange Fund
     which remains undistributed to the stockholders of the Company for 180 days
     after the Effective Time shall be delivered to Parent, upon demand, and any
     stockholders of the Company who have not previously complied with this
     Section 2.2 shall thereafter look only to Parent for payment of their claim
     for Parent Common Stock, any cash in lieu of fractional shares of Parent
     Common Stock and any dividends or distributions with respect to Parent
     Common Stock.
 
          (g) No Liability. To the extent permitted by applicable law, neither
     Parent nor the Company shall be liable to any holder of shares of Parent
     Common Stock or Company Common Stock, as the case may be, for such shares
     (or dividends or distributions with respect thereto) delivered to a public
     official pursuant to any applicable abandoned property, escheat or similar
     law.
 
          (h) Withholding Rights. Each of Parent and the Surviving Corporation
     shall be entitled to deduct and withhold from the consideration otherwise
     payable pursuant to this Agreement to any holder of shares of Company
     Common Stock such amounts as it is required to deduct and withhold with
     respect to the making of such payment under the Code, or any provision of
     state, local or foreign tax law. To the extent that amounts are so withheld
     by the Surviving Corporation or Parent, as the case may be, such withheld
     amounts shall be treated for all purposes of this Agreement as having been
     paid to the holder of the shares of Company Common Stock in respect of
     which such deduction and withholding was made by the Surviving Corporation
     or Parent, as the case may be.
 
          (i) Lost Certificates. If any Certificate shall have been lost, stolen
     or destroyed, upon the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen or destroyed and, if required
     by the Surviving Corporation, the posting by such person of a bond in such
     reasonable amount as the Surviving Corporation may direct as indemnity
     against any claim that may be made against it with respect to such
     Certificate, the Exchange Agent will issue in exchange for such lost,
     stolen or destroyed Certificate the shares of Parent Common Stock and any
     cash in lieu of fractional shares, and unpaid dividends and distributions
     on shares of Parent Common Stock deliverable in respect thereof pursuant to
     this Agreement.
 
          (j) Affiliates. Notwithstanding anything herein to the contrary,
     Certificates surrendered for exchange by any Affiliate (as defined in
     Section 7.10) of the Company shall not be exchanged until Parent has
     received an Affiliate Agreement (as defined in Section 7.10) from such
     Affiliate.

                                  ARTICLE III
 
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB
 
     Parent and Merger Sub represent and warrant to the Company that the
statements contained in this Article III are true and correct except as set
forth herein and in the disclosure schedule delivered by Parent to the Company
prior to the execution and delivery of this Agreement (the "Parent Disclosure
Schedule"). The Parent Disclosure Schedule shall be arranged in sections and
paragraphs corresponding to the numbered and lettered sections and paragraphs
contained in this Article III and the disclosure in any section or paragraph
shall qualify other sections and paragraphs in this Article III only to the
extent that it is reasonably apparent from a reading of such disclosure that it
also qualifies or applies to such other sections and paragraphs.
 
     3.1  Organization of Parent and Merger Sub. Each of Parent and its
Subsidiaries (as defined below), including Merger Sub, is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation, has all requisite corporate power to own,
lease and operate its property and to carry on its business as now being
conducted and as proposed to be conducted, and is duly qualified to do business
and is in good standing as a foreign corporation in each jurisdiction in which
the failure to be so qualified would have a Parent Material Adverse Effect (as
defined below). Except as set forth in the Parent SEC Reports (as defined in
Section 3.4) filed prior to the date hereof, neither Parent nor any of its
Subsidiaries directly or indirectly own any equity or similar interest in, or
any interest convertible into or exchangeable or exercisable for, any
corporation, partnership, joint venture or other business association or entity,
excluding securities in any publicly traded company held for investment by
Parent and comprising less than five percent (5%) of the outstanding stock of
such company. As used in this Agreement, the word "Subsidiary" means, with
respect to any party, any corporation or other organization, whether
incorporated or unincorporated, of which (a) such party or any other Subsidiary
of such party is a general partner (excluding partnerships, the general
partnership interests of which held by such party or any Subsidiary of such
party do not have a majority of the voting interest in such partnership) or (b)
at least a majority of the securities or other interests having by their terms
ordinary voting power to elect a majority of the Board of Directors or others
performing similar functions with respect to such corporation or other
organization is directly or indirectly owned or controlled by such party or by
any one or more of its Subsidiaries, or by such party and one or more of its
Subsidiaries. As used in this Agreement, any reference to a party's "knowledge"
means, with respect to a matter, such party's actual knowledge after due and
diligent inquiry of officers, directors and other employees of such party and
its Subsidiaries reasonably believed to have knowledge of such matter. For
purposes of this Agreement, the term "Parent Material Adverse Effect" means any
effect that is, or would reasonably be expected to be, materially adverse to the
business, properties, financial condition or results of operations of Parent and
its Subsidiaries, taken as a whole; provided, however, that (i) any adverse
change, event or effect that is demonstrated to be primarily caused by the
announcement or pendency of the Merger shall not be taken into account in
determining whether there has been or would be a "Parent Material Adverse
Effect" on or with respect to Parent and its Subsidiaries, taken as a whole, and
(ii) any adverse change in the stock price of Parent as quoted on the Nasdaq
National Market shall not be taken into account in determining whether there has
been or would be a "Parent Material Adverse Effect" on or with respect to Parent
and its Subsidiaries, taken as a whole.
 
     3.2  Parent Capital Structure.
 
     (a) The authorized capital stock of Parent consists of 60,000,000 shares of
Common Stock, $.01 par value, and 5,000,000 shares of Preferred Stock, $.01 par
value ("Parent Preferred Stock"). As of April 30, 1998, (i) 15,516,770 shares of
Parent Common Stock were issued and outstanding, all of which are validly
issued, fully paid and nonassessable, (ii) no shares of Parent Common Stock were
held in the treasury of Parent or by Subsidiaries of Parent. Section 3.2 of the
Parent Disclosure Schedule shows the number of shares of Parent Common Stock
reserved for future issuance pursuant to stock options granted and outstanding
as of April 30, 1998 and the plans under which such options were granted
(together with the 1997 Employee Stock Purchase Plan, the "Parent Stock Plans").
No material change in such capitalization has occurred between April 30, 1998
and the date of this Agreement. As of the date of this Agreement, none of the
shares of Parent Preferred Stock are issued and outstanding. All shares of
Parent Common Stock, subject to issuance as
 
                                       A-5
<PAGE>   139
 
specified above, are duly authorized and, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
shall be validly issued, fully paid and nonassessable. There are no obligations,
contingent or otherwise, of Parent or any of its Subsidiaries to repurchase,
redeem or otherwise acquire any shares of Parent Common Stock or the capital
stock of any Subsidiary or to provide funds to or make any material investment
(in the form of a loan, capital contribution or otherwise) in any such
Subsidiary or any other entity other than guarantees of bank obligations of
Subsidiaries entered into in the ordinary course of business. All of the
outstanding shares of capital stock of each of Parent's Subsidiaries are duly
authorized, validly issued, fully paid and nonassessable and all such shares
(other than directors' qualifying shares in the case of foreign Subsidiaries)
are owned by Parent or another Subsidiary free and clear of all security
interests, liens, claims, pledges, agreements, limitations in Parent's voting
rights, charges or other encumbrances of any nature.
 
     (b) Except as set forth in this Section 3.2 or as reserved for future
grants of options and issuances of shares of Common Stock under the Parent Stock
Plans, there are no equity securities of any class of Parent or any of its
Subsidiaries, or any security exchangeable into or exercisable for such equity
securities, issued, reserved for issuance or outstanding. Except as set forth in
the Parent SEC Reports filed prior to the date hereof or disclosed in Section
3.2 of the Parent Disclosure Schedule, there are no options, warrants, equity
securities, calls, rights, commitments or agreements of any character to which
Parent or any of its Subsidiaries are a party or by which it is bound obligating
Parent or any of its Subsidiaries to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock of Parent or any
of its Subsidiaries or obligating Parent or any of its Subsidiaries to grant,
extend, accelerate the vesting of, change the price of, or otherwise amend or
enter into any such option, warrant, equity security, call, right, commitment or
agreement. To the knowledge of Parent, there are no voting trusts, proxies or
other voting agreements or understandings with respect to the shares of capital
stock of Parent.
 
     3.3  Authority; No Conflict; Required Filings and Consents.
 
     (a) Each of Parent and Merger Sub has all requisite corporate power and
authority to enter into this Agreement and in the case of Parent, the Stock
Option Agreement, and to consummate the transactions contemplated by this
Agreement and in the case of Parent, the Stock Option Agreement. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated by this Agreement by Parent and Merger Sub and in the case of
Parent, the Stock Option Agreement, have been duly authorized by all necessary
corporate action on the part of each of Parent and Merger Sub (including the
approval of the Merger by Parent as the sole stockholder of Merger Sub), subject
only to the approval of the Merger by Parent's stockholders. This Agreement has
been duly executed and delivered by Parent and Merger Sub, and constitutes the
valid and binding obligations of Parent and Merger Sub, enforceable in
accordance with their terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles (the
"Bankruptcy and Equity Exception").
 
     (b) The execution and delivery of this Agreement, and in the case of
Parent, the Stock Option Agreement, by Parent and Merger Sub, does not, and the
consummation of the transactions contemplated by this Agreement and the Stock
Option Agreement will not, (i) conflict with, or result in any violation or
breach of, any provision of the Certificate of Incorporation or Bylaws of Parent
or Merger Sub, each as amended to date, (ii) result in any violation of, or
default under or breach of, or constitute (with or without notice or lapse of
time, or both) a default (or give rise to a right of termination, cancellation
or acceleration of any obligation or loss of any material benefit) under, or
require a consent or waiver under, any of the terms, conditions or provisions of
any note, bond, mortgage, indenture, lease, contract or other agreement,
instrument or obligation to which Parent or any of its Subsidiaries are a party
or by which any of them or any of their properties or assets may be bound, or
(iii) conflict with or violate any permit, concession, franchise, license,
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to Parent or any of its Subsidiaries or any of its or their properties or
assets, except in the case of clauses (ii) and (iii) for any such conflicts,
violations, defaults, terminations, cancellations or accelerations that are not,
individually or in the aggregate, reasonably likely to have a Parent Material
Adverse Effect.
 
                                       A-6
<PAGE>   140
 
     (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any court, administrative agency or commission or
other governmental authority or instrumentality ("Governmental Entity") is
required by or with respect to Parent or any of its Subsidiaries in connection
with the execution and delivery of this Agreement and the Stock Option Agreement
or the consummation of the transactions contemplated hereby or thereby, except
for (i) the filing of the Registration Statement (as defined in Section 3.16
below) with the Securities and Exchange Commission (the "SEC") in accordance
with the Securities Act of 1933, as amended ("Securities Act"), (ii) the filing
of the Certificate of Merger with the Secretary of State of Georgia, (iii) the
filing of the Joint Proxy Statement (as defined in Section 3.16 below) with the
SEC in accordance with the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and the National Association of Securities Dealers, Inc., and
any clearance thereof by the SEC, (iv) the filing with the Nasdaq National
Market of a Notification Form for Listing of Additional Shares, (v) such
consents, approvals, orders, authorizations, registrations, declarations and
filings as may be required under applicable state securities laws and the laws
of any foreign country and (vi) such other consents, authorizations, filings,
approvals and registrations which, if not obtained or made, would not be
reasonably likely to have a Parent Material Adverse Effect.
 
     3.4  SEC Filings; Financial Statements.
 
     (a) Parent has filed all forms, reports and documents required to be filed
by Parent with the SEC since December 17, 1997, (collectively, the "Parent SEC
Reports"). The Parent SEC Reports (i) at the time filed or, with respect to
registration statements filed with the SEC under the Securities Act, as of the
effective date thereof, complied in all material respects with the applicable
requirements of the Securities Act, and the Exchange Act, as the case may be,
and (ii) did not at the time they were filed (or if amended or superseded by a
filing prior to the date of this Agreement, then on the date of such filing)
contain any untrue statement of a material fact or omit to state a material fact
required to be stated in such Parent SEC Reports or necessary in order to make
the statements in such Parent SEC Reports, in light of the circumstances under
which they were made, not misleading. None of Parent's Subsidiaries are required
to file any forms, reports or other documents with the SEC.
 
     (b) Each of the consolidated financial statements (including, in each case,
any related notes) contained in the Parent SEC Reports complied as to form in
all material respects with the applicable published rules and regulations of the
SEC with respect thereto, was prepared in accordance with U.S. generally
accepted accounting principles ("GAAP") applied on a consistent basis throughout
the periods involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited statements, as permitted by Form 10-Q of
the SEC) and fairly presented the consolidated financial position of Parent and
its Subsidiaries as of the dates and the consolidated results of its operations
and cash flows for the periods indicated, except that the unaudited interim
financial statements were or are subject to normal and recurring year-end
adjustments which were not or are not expected to be material in amount. The
unaudited balance sheet of Parent as of April 30, 1998 is referred to herein as
the "Parent Balance Sheet."
 
     3.5  No Undisclosed Liabilities. Except as disclosed in the Parent SEC
Reports filed prior to the date hereof, and except for normal or recurring
liabilities incurred since April 30, 1998 in the ordinary course of business
consistent with past practices, Parent and its Subsidiaries do not have any
liabilities, either accrued, contingent or otherwise (whether or not required to
be reflected in financial statements in accordance with GAAP), and whether due
or to become due, which individually or in the aggregate are reasonably likely
to have a Parent Material Adverse Effect.
 
     3.6  Absence of Certain Changes or Events. Except as disclosed in the
Parent SEC Reports filed prior to the date hereof, during the period commencing
on the date of the Parent Balance Sheet and ending on the date of this
Agreement, the Parent and its Subsidiaries have conducted their businesses only
in the ordinary course and in a manner consistent with past practice and, during
such period, there has not been (i) any change in the financial condition,
results of operations, business or properties of the Parent and its
Subsidiaries, taken as a whole, which has had or could reasonably be expected to
have a Parent Material Adverse Effect; (ii) any damage, destruction or loss
(whether or not covered by insurance) with respect to the Parent or any of its
Subsidiaries having a Parent Material Adverse Effect; (iii) any material change
by the
 
                                       A-7
<PAGE>   141
 
Parent in its accounting methods, principles or practices to which Parent has
not advised Company promptly thereof; or (iv) any revaluation by the Parent of
any of its assets having a Parent Material Adverse Effect.
 
     3.7  Taxes.
 
     (a) All Tax returns, statements, reports, declarations and other forms and
documents (including without limitation estimated Tax returns and reports and
material information returns and reports) required to be filed with any Tax
authority with respect to any Taxable period ending on or before the Closing, by
or on behalf of Parent (collectively, "Tax Returns" and individually a "Tax
Return"), have been or will be completed and filed when due (including any
extensions of such due date) and all amounts shown due on such Tax Returns on or
before the Effective Time (and all other Taxes due and payable on or before the
Effective Time) have been or will be paid on or before such date. The Parent's
consolidated financial statements (i) fully accrue all actual and contingent
liabilities for Taxes with respect to all periods through April 30, 1998 and
Parent has not and will not incur any Tax liability materially in excess of the
amount reflected on the Parent Balance Sheet with respect to such periods, other
than Taxes incurred in the ordinary course of its business following April 30,
1998, and (ii) properly accrues in accordance with GAAP all material liabilities
for Taxes payable after April 30, 1998 with respect to all transactions and
events occurring on or prior to such date.
 
     (b) For purposes of this Agreement, the following terms have the following
meanings: "Tax" (and, with correlative meaning, "Taxes" and "Taxable") means any
and all taxes including, without limitation, (i) any net income, alternative or
add-on minimum tax, gross income, gross receipts, sales, use, ad valorem,
transfer, franchise, profits, value added, net worth, license, withholding,
payroll, employment, excise, severance, stamp, occupation, premium, property,
environmental or windfall profit tax, custom, duty or other tax governmental fee
or other like assessment or charge of any kind whatsoever, together with any
interest or any penalty, addition to tax or additional amount imposed by any
Governmental Entity (a "Tax authority") responsible for the imposition of any
such tax (domestic or foreign), (ii) any liability for the payment of any
amounts of the type described in (i) as a result of being a member of an
affiliated, consolidated, combined or unitary group for any Taxable period or as
the result of being a transferee or successor thereof and (iii) any liability
for the payment of any amounts of the type described in (i) or (ii) as a result
of any express or implied obligation to indemnify any other person. As used in
this Section 3.7, the term "Parent" means Parent and any entity included in, or
required under GAAP to be included in, any of the Parent consolidated financial
statements.
 
     3.8  Properties.
 
     (a) Neither the Parent nor any of its Subsidiaries own any real property.
 
     (b) All material real property leases of the Parent and its Subsidiaries
are in good standing, valid and effective in accordance with their respective
terms, and neither the Parent nor any of its Subsidiaries are in default under
any of such leases.
 
     3.9  Intellectual Property.
 
     (a) The Parent and its Subsidiaries own, or are licensed or otherwise
possess legally enforceable rights to use, all patents, trademarks, trade names,

     The Company represents and warrants to Parent and Merger Sub that the
statements contained in this Article IV are true and correct except as set forth
herein and in the disclosure schedule delivered by the Company to Parent prior
to the execution and delivery of this Agreement (the "Company Disclosure
Schedule"). The Company Disclosure Schedule shall be arranged in sections and
paragraphs corresponding to the numbered and lettered sections and paragraphs
contained in this Article IV and the disclosure in any section or paragraph

is a corporation duly organized, validly existing and in good standing under the

Section 4.4) filed prior to the date hereof, neither the Company nor any of its
Subsidiaries directly or indirectly own any equity or similar interest in, or

corporation, partnership, joint venture or other business association or entity,
excluding securities in any publicly traded company held for investment by the
Company and comprising less than five percent (5%) of the outstanding stock of
such company. For purposes of this Agreement, the term "Company Material Adverse
Effect" means any effect that is, or would reasonably be expected to be,
materially adverse to the business, properties, financial condition or results
of operations of the Company and its Subsidiaries, taken as a whole; provided,
however, that (a) any adverse change, event or effect that is demonstrated to be
primarily caused by the announcement or pendency of the Merger shall not be
taken into account in determining whether there has been or would be a "Company
Material Adverse Effect" on or with respect to the Company and its Subsidiaries,
taken as a whole, and (b) any adverse change in the stock price of the Company
as quoted on the Nasdaq National Market shall not be taken into account in
determining whether there has been or would be a "Company Material Adverse
Effect" on or with respect to the Company and its Subsidiaries, taken as a
whole.

and documents required to be filed by the Company with the SEC since December

financial position of the Company and its Subsidiaries as of the dates and the
consolidated results of its operations and cash flows for the periods indicated,

Taxes (other than for current Taxes not yet due and payable) upon the assets of
Company. Company is in full compliance with all the terms and conditions of any
Tax exemptions or other Tax-sharing agreement or order of a foreign government

continued validity and effectiveness of any such Tax exemption or other
Tax-sharing agreement or order. Neither Company nor any person on behalf of
Company has entered into or will enter into any agreement or consent pursuant to
the collapsible corporation provisions of Section 341(f) of the Code (or any

reflected on the Company Tax Returns for such periods, copies of which have been
provided or made available to Parent. After the date of this Agreement, no
material election with respect to Taxes will be made without the prior written
consent of Parent, which consent will not be unreasonably withheld or delayed.

Company and Parent shall prepare and file with the SEC the Joint Proxy
Statement, and Parent shall prepare and file with the SEC the Registration
Statement, in which the Joint Proxy Statement will be included as a prospectus,
provided that Parent may delay the filing of the Registration Statement until
approval of the Joint Proxy Statement by the SEC. The Company and Parent shall
use all reasonable efforts to cause the Registration Statement to become
effective as soon after such filing as practical; provided, however, that Parent
shall have no obligation to agree to account for the Merger as a "purchase" in
order to cause the Registration Statement to become effective. The Joint Proxy
Statement, and any amendment or supplement thereto, shall include the
recommendation of the Board of Directors of Parent and the recommendation of the
Board of Directors of the Company in favor of this Agreement and the Merger;
provided that the Board of Directors of either party may withdraw such
recommendation if such Board of Directors believes in its good faith reasonable
judgment, based upon and consistent with advice received in consultation with
outside legal counsel, that the withdrawal of such recommendation is necessary
for such Board of Directors to comply with its fiduciary duties under applicable
law.
 
     (b) The Company and Parent shall make all necessary filings with respect to
the Merger under the Securities Act, the Exchange Act, applicable state blue sky
laws and the rules and regulations thereunder.

     (a) Parent and the Company shall each call a meeting of its respective
stockholders to be held as promptly as practicable for the purpose of voting, in
each case, upon this Agreement and the Merger. Subject to Sections 7.2 and 7.3,
Parent and the Company will, through their respective Boards of Directors,
recommend to their respective stockholders approval of such matters and will
coordinate and cooperate with respect to the timing of such meetings and shall
use their best efforts to hold such meetings on the same day and as soon as
practicable after the date hereof and shall not postpone or adjourn (other than
for the absence of a quorum) their respective stockholders' meetings without the
consent of the other party. Subject to Sections 7.2 and 7.3, each party shall
use all reasonable efforts to solicit from stockholders of such party proxies in
favor of such matters.
 
     (b) Parent may also submit additional proposals to its stockholders at the
Parent Stockholders' Meeting, separate from the proposals referred to in Section
7.5(a). The approval by Parent's stockholders of such additional proposals shall
not be a condition to the closing of the Merger under this Agreement.
 
     7.6  Legal Conditions to Merger.
 
     (a) Subject to Sections 7.2 and 7.3, Parent and the Company shall each use
their best efforts to (i) take, or cause to be taken, all appropriate action,
and do, or cause to be done, all things necessary and proper under applicable
law to consummate and make effective the transactions contemplated hereby as
promptly as practicable, (ii) obtain from any Governmental Entity any consents,
licenses, permits, waivers, approvals, authorizations or orders required to be

<PAGE>   156
 
consummation of the transactions contemplated hereby, including, without
limitation, the Merger, and (iii) as promptly as practicable, make all necessary
filings, and thereafter make any other required submissions, with respect to
this Agreement and the Merger required under (A) the Securities Act and the
Exchange Act, and any other applicable federal or state securities laws and (B)
any applicable law. Parent and the Company shall cooperate with each other in
connection with the making of all such filings, including providing copies of
all such documents to the non-filing party and its advisors prior to filing and,
if requested, to accept all reasonable additions, deletions or changes suggested
in connection therewith. Parent and the Company shall use their best efforts to
furnish to each other all information required for any application or other
filing to be made pursuant to the rules and regulations of any applicable law
(including all information required to be included in the Joint Proxy Statement
and the Registration Statement) in connection with the transactions contemplated
by this Agreement.
 
     (b) The Company and Parent agree, and shall cause each of their respective
Subsidiaries, to cooperate and to use their respective best efforts to obtain
any government clearances or approvals required for Closing under any Federal,
state or foreign law, regulation, rule, order or decree designed to prohibit,
restrict or regulate actions for the purpose or effect of monopolization or
restraint of trade (collectively, "Antitrust Laws"), to respond to any
government requests for information under any Antitrust Law, and to contest and
resist any action, including any legislative, administrative or judicial action,
and to have vacated, lifted, reversed or overturned any decree, judgment,
injunction or other order (whether temporary, preliminary or permanent) (an
"Order") that restricts, prevents or prohibits the consummation of the Merger or
any other transactions contemplated by this Agreement under any Antitrust Law.
The parties hereto will consult and cooperate with one another, and consider in
good faith the views of one another, in connection with any analyses,
appearances, presentations, memoranda, briefs, arguments, opinions and proposals
made or submitted by or on behalf of any party hereto in connection with
proceedings under or relating to any Antitrust Law. In the event of a challenge
to the transactions contemplated by this Agreement pursuant to any Antitrust
laws, Parent and the Company shall use their best efforts to defeat such
challenge, including by institution and defense of litigation, or to settle such
challenge on terms that permit the consummation of the Merger; provided,
however, that nothing herein shall require either party to agree to divest or
hold separate any portion of its business, product line or assets or otherwise
take action that could reasonably be expected to have a Parent Material Adverse
Effect, a Company Material Adverse Effect or an effect to Parent combined with
the Surviving Corporation after the Effective Time comparable to either a Parent
Material Adverse Effect or a Company Material Adverse Effect. In case at any
time after the Effective Time any further action is necessary or desirable to
carry out the purposes of this Agreement or to vest the Surviving Corporation
with full title to all properties, assets, rights, approvals, immunities and
franchises of either of the Constituent Corporations, the proper officers and
directors of each party to this Agreement shall take all such necessary action.
 
     (c) Each of Parent and Company shall give (or shall cause their respective
Subsidiaries to give) any notices to third parties, and use, and cause their
respective Subsidiaries to use, their best efforts to obtain any third party
consents related to or required in connection with the Merger that are (i)
necessary to consummate the transactions contemplated hereby, (ii) disclosed or
required to be disclosed in the Parent Disclosure Schedule or the Company
Disclosure Schedule, as the case may be, or (iii) required to prevent a Parent
Material Adverse Effect or a Company Material Adverse Effect from occurring
prior to or after the Effective Time.
 
     7.7  Public Disclosure. The Company and Parent shall consult with each
other before issuing any press release or otherwise making any public statement
with respect to the Merger or this Agreement and shall not issue any such press
release or make any such public statement prior to such consultation, except as

best efforts to cause the Merger to be treated as a reorganization within the
meaning of Section 368(a) of the Code.
 
     7.9  Pooling Accounting. From and after the date hereof and until the
Effective Time, Parent and the Company shall each use its best efforts to cause
the business combination to be effected by the Merger to be
 
                                      A-23
<PAGE>   157
 
accounted for as a pooling of interests and to take such action as may be
reasonably necessary to permit such treatment. Each of Parent and the Company
shall use its best efforts to cause its respective Affiliates not to take any
action that would adversely affect the ability of Parent to account for the
business combination to be effected by the Merger as a pooling of interests.
 
     7.10  Affiliate Agreements. Upon the execution of this Agreement, the
Company and Parent will provide each other with a list of those persons who are,
in the Company's or Parent's respective reasonable judgment, "affiliates" of the
Company or Parent, respectively, within the meaning of Rule 145 promulgated
under the Securities Act ("Rule 145") (each such person who is an "affiliate" of
the Company or Parent within the meaning of Rule 145 is referred to as an
"Affiliate"). The Company and Parent shall provide each other with such
information and documents as Parent or the Company shall reasonably request for
purposes of reviewing such list and shall notify the other party in writing
regarding any change in the identity of its Affiliates prior to the Closing
Date. Parent and the Company shall each use its best efforts to deliver or cause
to be delivered to each within thirty days of the date hereof (and in any case
prior to the Effective Time) from each of its Affiliates, an executed Affiliate
Agreement, in form attached hereto as Exhibit C-1, in the case of Affiliates of
the Company, and in the form attached hereto as Exhibit C-2, in the case of
Affiliates of Parent (each, an "Affiliate Agreement"). Parent shall be entitled
to place appropriate legends on the certificates evidencing any Parent Common
Stock to be received by such Affiliates of the Company pursuant to the terms of
this Agreement, and to issue appropriate stop transfer instructions to the
transfer agent for the Parent Common Stock, consistent with the terms of the

stockholder that is not then an Affiliate of Parent).
 
     7.11  Nasdaq Quotation. Parent shall use its best efforts to cause the
shares of Parent Common Stock to be issued in the Merger to be approved for
quotation on the Nasdaq National Market, subject to official notice of issuance,
prior to the Closing Date.
 
     7.12  Stock Plans.
 
     (a) At the Effective Time, each outstanding option to purchase shares of
Company Common Stock (a "Company Stock Option") under the Company Stock Plans,
whether vested or unvested, shall be deemed to constitute an option to acquire,
on the same terms and conditions as were applicable under such Company Stock
Option, the same number of shares of Parent Common Stock as the holder of such
Company Stock Option would have been entitled to receive pursuant to the Merger
had such holder exercised such option in full immediately prior to the Effective
Time (rounded downward to the nearest whole number), at a price per share
(rounded upward to the nearest whole cent) equal to (y) the aggregate exercise
price for the shares of Company Common Stock purchasable pursuant to such
Company Stock Option immediately prior to the Effective Time divided by (z) the
number of full shares of Parent Common Stock deemed purchasable pursuant to such
Company Stock Option in accordance with the foregoing.
 
     (b) As soon as practicable after the Effective Time, Parent shall deliver
to the participants in Company Stock Plans appropriate notice setting forth such
participants' rights pursuant thereto and the grants made pursuant to Company
Stock Plans shall continue in effect on the same terms and conditions (subject
to the adjustments required by this Section 7.12 after giving effect to the
Merger).
 
     (c) At the Effective Time, by virtue of the Merger and without the need of
any further corporate action, Parent shall assume the Company Stock Plans, with
the result that all obligations of the Company under the Company Stock Plans,
including with respect to Company Stock Options outstanding at the Effective
Time under each Company Stock Plan, shall be obligations of Parent following the
Effective Time. Parent shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery under
Company Stock Plans assumed in accordance with this Section 7.12. As soon as
practicable after the Effective Time, Parent shall file a registration statement
on Form S-8 (or any successor or other appropriate forms), or another
appropriate form with respect to the shares of Parent Common Stock subject to
such options, and shall use its best efforts to maintain the effectiveness of
such registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
options remain outstanding.

options to acquire Parent Common Stock in accordance with this Section 7.12, and
that no consent of the holders of the Company Stock Options is required in
connection with such conversion.
 
     7.13  Brokers or Finders. Each of the Company and Parent represents, as to
itself, its Subsidiaries and its Affiliates, that no agent, broker, investment
banker, financial advisor or other firm or person is or will be entitled to any
broker's or finder's fee or any other commission or similar fee in connection
with any of the transactions contemplated by this Agreement, except BancAmerica

with Parent's agreement with such firm, and First Albany Corporation, whose fees
and expenses will be paid by the Company in accordance with the Company's
agreements with such firm (a copy of which have been delivered by the Company to
Parent prior to the date of this Agreement). Each of the Company and Parent
agrees to indemnify and hold the other harmless from and against any and all
claims, liabilities or obligations with respect to any such fees, commissions or
expenses asserted by any person on the basis of any act or statement alleged to
have been made by such party or any of its Affiliates.

reasonable efforts to cause to be delivered to Parent and the Company a letter
of Ernst & Young LLP, the Company's independent auditors, dated a date within

become effective and addressed to Parent, in form reasonably satisfactory to
Parent and customary in scope and substance for letters delivered by independent
public accountants in connection with registration statements similar to the
Registration Statement.
 
     7.15  Letter of Parent's Accountants. Parent shall use all reasonable
efforts to cause to be delivered to the Company and Parent a letter of

to the Company and customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements
similar to the Registration Statement.
 
     7.16  Schedules. From time to time prior to the Closing Date, each of
Parent and the Company will promptly supplement or amend the Parent or the
Company Disclosure Schedules, as the case may be, with respect to any matter
hereafter arising that, if existing or occurring at or prior to the date of this
Agreement, would have been required to be set forth or described in the Parent
or the Company Disclosure Schedules, as the case may be, or that is necessary to
correct any information in the Parent or the Company Disclosure Schedules, as
the case may be, or in any representation and warranty of each of Parent and the
Company that has been rendered inaccurate thereby. For purposes of determining
the accuracy of the respective representations and warranties contained in
Articles III and IV, and in order to determine the fulfillment of the conditions
set forth in Article VIII, the Parent or the Company Disclosure Schedules, as
the case may be, shall be deemed to include only that information contained
therein on the date of this Agreement and shall be deemed to exclude any
information contained in any subsequent supplement or amendment thereto unless
such changes reflect actions taken in compliance with the provisions of Articles
V, VI and VIII hereof.
 
     7.17  Indemnification.
 
     (a) From and after the Effective Time, Parent agrees that it will cause the
Surviving Corporation to, indemnify and hold harmless each present and former

costs or expenses (including attorneys' fees), judgments, fines, losses, claims,
damages, liabilities or amounts paid in settlement (collectively, "Costs")
incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of or pertaining to matters existing or occurring at or prior to the
Effective Time, whether asserted or claimed prior to, at or after the Effective
Time, to the fullest extent that the Company would have been permitted under GCC
and its certificate of incorporation, bylaws or resolutions of the Board of
Directors of the Company in effect on the date hereof to indemnify such
Indemnified Party (and the Surviving Corporation shall also
 
                                      A-25
<PAGE>   159
 
advance expenses as incurred to the fullest extent permitted under applicable
law, provided the Indemnified Party to whom expenses are advanced provides an
undertaking to repay such advances if it is ultimately determined that such
Indemnified Party is not entitled to indemnification).
 
     (b) The provisions of this Section 7.17 are intended to be in addition to
the rights otherwise available to the current officers and directors of the
Company by law, charter, statute, bylaw, resolution of the Board of Directors of
the Company or agreement, and shall operate for the benefit of, and shall be
enforceable by, each of the Indemnified Parties, their heirs and their
representatives.

     stockholders of the Company tender their shares in such tender offer or
     exchange offer; or (iv) for any other reason the Company fails to call and
     hold the Company Stockholders' Meeting by the Outside Date (provided that
     Parent's right to terminate this Agreement under such clause (iv) shall not
     be available if at such time the Company would be entitled to terminate

          (f) by the Company, if (i) the Board of Directors of the Parent shall
     have withdrawn or modified its recommendation of this Agreement or the
     Merger, or (ii) for any other reason the Parent fails to call and hold the
     Parent Stockholders' Meeting by the Outside Date (provided that Company's

          (g) by the Company or Parent, if there has been a breach of any
     representation, warranty, covenant or agreement on the part of the other
     party set forth in this Agreement, which breach (i) causes the conditions
     set forth in Section 8.2(a) or (b) (in the case of termination by the
     Company) or 8.3(a) or (b) (in the case of termination by Parent) not to be

as provided in Section 9.1, this Agreement shall immediately become void and
there shall be no liability or obligation on the part of the Company, Parent,
Merger Sub or their respective officers, directors, stockholders or Affiliates;
provided, however that, (a) except as set forth in (b) below, no such
termination shall limit liability for any willful breach of this Agreement, (b)
the sole remedy for any termination of this Agreement pursuant to Section 9.1(e)
or (f) shall be the fee payment provided in Section 9.3(b) or 9.3(c), as the

full force and effect and survive any termination of this Agreement.

purpose the outstanding equity securities of Subsidiaries of the Company, and
the entity surviving any merger or business combination including any of them)
of the Company having a fair market value (as determined by the Board of
Directors of the Company or Parent, as the case may be, in good faith) equal to
more than 20% of the fair market value of all the assets of the Company and its
Subsidiaries, taken as a whole, immediately prior to such transaction, or (iv)

action taken or authorized by their respective Boards of Directors, at any time
before or after approval of the matters presented in connection with the Merger

stockholders without such further approval. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.
 
     9.6  Extension; Waiver. At any time prior to the Effective Time, including

                             STOCK OPTION AGREEMENT
 
     This STOCK OPTION AGREEMENT, dated June 29, 1998 (this "Agreement"), is by
and between IQ SOFTWARE CORPORATION, a Georgia corporation (the "Grantor") and
INFORMATION ADVANTAGE, INC. a Delaware corporation (the "Grantee").
 
     WHEREAS, the Grantee, the Grantor and IAC Merger Corp., a Georgia
corporation and a wholly owned subsidiary of the Grantee ("Merger Sub"), are
entering into an Agreement and Plan of Merger, dated the date hereof (the
"Merger Agreement"), which provides, among other things, for the merger (the
"Merger") of Merger Sub with and into the Grantee;
 
     WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, the Grantee has requested that the Grantor grant to the Grantee an
option to purchase 930,169 shares of Common Stock, par value $0.00033 per share,
of the Grantor (the "Common Stock"), upon the terms and subject to the
conditions hereof; and
 
     WHEREAS, in order to induce the Grantee to enter into the Merger Agreement,
the Grantor is willing to grant the Grantee the requested option.
 
     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:
 
     1. The Option; Exercise; Adjustments; Payment of Spread.
 
     (a) Contemporaneously herewith the Grantee, Merger Sub and the Grantor are
entering into the Merger Agreement. Subject to the other terms and conditions
set forth herein, the Grantor hereby grants to the Grantee an irrevocable option
(the "Option") to purchase up to 930,169 shares of Common Stock (the "Shares")
at a cash purchase price equal to the lowest of (i) $11.75 per Share, (ii) the
average closing price of the Common Stock on the Nasdaq National Market for the
five consecutive trading days beginning on and including the day that the Merger
is publicly announced, or (iii) the average closing price of the Common Stock on
the Nasdaq National Market for the five consecutive trading days immediately
preceding the public announcement of an Alternative Transaction (as defined in
the Merger Agreement) involving Grantor giving rise to the right to exercise
this Option pursuant to Section 2 below (the "Purchase Price"). The Option may
be exercised by the Grantee, in whole or in part, at any time, or from time to
time, following the occurrence of one of the events set forth in Section 2(b)
hereof and prior to the termination of the Option in accordance with the terms
of this Agreement.
 
     (b) In the event the Grantee wishes to exercise the Option, the Grantee
shall send a written notice to the Grantor (the "Stock Exercise Notice")
specifying a date not later than 10 business days and not earlier than the next
business day following the date such notice is given for the closing of such
purchase. In the event of any change in the number of issued and outstanding
shares of Common Stock by reason of any stock dividend, stock split, split-up,
recapitalization, merger or other change in the corporate or capital structure
of the Grantor, the number of Shares subject to this Option and the purchase
price per Share shall be appropriately adjusted to restore to the Grantee its
rights hereunder, including its right to purchase Shares representing 19.9% of
the capital stock of the Grantor entitled to vote generally for the election of
the directors of the Grantor which is issued and outstanding immediately prior
to the exercise of the Option at an aggregate purchase price equal to the
Purchase Price multiplied by 930,169.
 
     (c) If at any time the Option is then exercisable pursuant to the terms of
Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to
purchase Shares provided in Section 1(a) hereof, to send a written notice to the
Grantor (the "Cash Exercise Notice") specifying a date not later than 20
business days and not earlier than 10 business days following the date such
notice is given on which date the Grantor shall pay to the Grantee an amount in
cash equal to the Spread (as hereinafter defined) multiplied by all or such
portion of the Shares subject to the Option as Grantee shall specify. As used
herein "Spread" shall mean the excess, if any, over the Purchase Price of the
higher of (x) if applicable, the highest price per share of
                                   Exhibit A-1
<PAGE>   168
 
Common Stock (including any brokerage commissions, transfer taxes and soliciting
dealers' fees) paid by any person in an Alternative Transaction (as defined in
the Merger Agreement) (the "Alternative Purchase Price") or (y) the closing
price of the shares of Common Stock on the Nasdaq National Market on the last
trading day immediately prior to the date of the Cash Exercise Notice (the
"Closing Price"). If the Alternative Purchase Price includes any property other
than cash, the Alternative Purchase Price shall be the sum of (i) the fixed cash
amount, if any, included in the Alternative Purchase Price plus (ii) the fair
market value of such other property. If such other property consists of
securities with an existing public trading market, the average of the closing
prices (or the average of the closing bid and asked prices if closing prices are
unavailable) for such securities in their principal public trading market on the
five trading days ending five days prior to the date of the Cash Exercise Notice
shall be deemed to equal the fair market value of such property. If such other
property consists of something other than cash or securities with an existing
public trading market and, as of the payment date for the Spread, agreement on
the value of such other property has not been reached, the Alternative Purchase
Price shall be deemed to equal the Closing Price. Upon exercise of its right to
receive cash pursuant to this Section 1(c), the obligations of the Grantor to
deliver Shares pursuant to Section 3 shall be terminated with respect to such
number of Shares for which the Grantee shall have elected to be paid the Spread.
 
     2. Conditions to Delivery of Shares. The Grantor's obligation to deliver
Shares upon exercise of the Option or the Spread upon exercise of the Grantor's
rights under Section 1(c) above is subject only to the conditions that:
 
     (a) No preliminary or permanent injunction or other order issued by any
federal or state court of competent jurisdiction in the United States
prohibiting the delivery of the Shares shall be in effect; and
 
     (b) A proposal for an Alternative Transaction involving Grantor shall have
been made prior to the date the Merger Agreement is terminated pursuant to the
terms thereof (the "Merger Termination Date") and one or more of the following
events shall have occurred on or after the date of the making of such proposal:
(1) the requisite vote of the stockholders of Grantor in favor of the Merger
shall not have been obtained at the Company Stockholders' Meeting (as such terms
are defined in the Merger Agreement) or any adjournment or postponement thereof;
(2) the Board of Directors of Grantor shall have withdrawn or modified its
recommendation of the Merger Agreement or the Merger; (3) the Board of Directors
of Grantor shall have recommended to the stockholders of Grantor an Alternative
Transaction (as defined in the Merger Agreement); (4) a tender offer or exchange
offer for 20% or more of the outstanding shares of Grantor Common Stock shall
have been commenced (other than by Grantee or an affiliate of Grantee) and the
Board of Directors of Grantor shall have recommended that the stockholders of
Grantor tender their shares in such tender or exchange offer; or (5) for any
reason Grantor shall have failed to call and hold the Company Stockholders'
Meeting (as defined in the Merger Agreement) by the Outside Date (as defined in
the Merger Agreement).
 
     3. The Closing.
 
     (a) Any closing hereunder shall take place on the date specified by the
Grantee in its Stock Exercise Notice or Cash Exercise Notice, as the case may
be, at 10:00 A.M., local time, at the offices of Gunderson Dettmer Stough
Villeneuve Franklin & Hachigian, LLP, 155 Constitution Drive, Menlo Park,
California or, if the conditions set forth in Section 2(a) have not then been
satisfied, on the second business day following the satisfaction of such
conditions, or at such other time and place as the parties hereto may agree (the
"Closing Date"). On the Closing Date, (i) in the event of a closing pursuant to
Section 1(b) hereof, the Grantor will deliver to the Grantee a certificate or
certificates, duly endorsed (or accompanied by duly executed stock powers),
representing the Shares in the denominations designated by the Grantee in its
Stock Exercise Notice and the Grantee will purchase such Shares from the Grantor
at the price per Share equal to the Purchase Price or (ii) in the event of a
closing pursuant to Section 1(c) hereof, the Grantor will deliver to the Grantee
cash in an amount determined pursuant to Section 1(c) hereof. Any payment made
by the Grantee to the Grantor, or by the Grantor to the Grantee, pursuant to
this Agreement shall be made by wire transfer of immediately available federal
funds to a bank designated by the party receiving such funds.

the execution and delivery of this Agreement by the Grantor and the consummation
by it of the transactions contemplated hereby do not require the consent,

which the Grantor or any of its subsidiaries or any of their respective
properties or assets is bound; and (e) no "fair price", "moratorium", "control

valid and binding obligation of Grantee; and (b) the Grantee is acquiring the
Option and, if and when it exercises the Option, will be acquiring the Shares
issuable upon the exercise thereof for its own account and not with a view to
distribution or resale in any manner which would be in violation of the
Securities Act.
 
     6. Listing of Shares; Governmental Consents; Directorship.
 
     (a) Subject to applicable law and the rules and regulations of the Nasdaq
National Market, the Grantor will promptly file an application to list the
Shares on the Nasdaq National Market and will use its best efforts to obtain
approval of such listing; provided, however, that if the Grantor is unable to
effect such listing on the Nasdaq National Market by the Closing Date, the
Grantor will nevertheless be obligated to deliver the Shares upon the Closing
Date. Each of the parties hereto will use its best efforts to obtain consents of
all third parties and governmental authorities, if any, necessary to the
consummation of the transactions contemplated.
 
     (b) Upon exercise by the Grantee of the Option, in whole or in part, for at
least 465,085 Shares (as adjusted for stock splits, stock dividends,
recapitalizations, mergers or other changes in the corporate or capital
structure of Grantor) the Grantee shall be entitled to designate one person to
be appointed to the Board of Directors of the Grantor. Within five business days
of the giving of notice by the Grantee to the Grantor of the name of such
designee, the Grantor, subject to the fiduciary obligations of the Board of
Directors of the Grantor, shall cause such designee to be appointed to the Board
of Directors of the Grantor. Thereafter, subject to the further provisions
hereof, the Grantor's nominating committee (or any other committee exercising a
similar function) shall recommend to the Board of Directors of the Grantor that
such person designated by the Grantee be included in the slate of nominees
recommended by the Board of Directors to the stockholders for election as
directors at each annual meeting of stockholders of the Grantor. In the event
that the designee of the Grantee shall cease to serve as a director for any
reason, the Grantee shall give notice to the Grantor of the name of a designee
to fill such vacancy in accordance with the second and third sentences of this
Section 6(b). If any such person has been designated by the Grantee and not
approved by the Board of
 
                                   Exhibit A-3
<PAGE>   170
 
Directors, the Grantee shall be permitted to designate a substitute designee for
such person in accordance with this Section 6(b). Notwithstanding the foregoing,
the Grantor shall not be required to nominate the designee of the Grantee, and
shall be entitled to request and receive the resignation of any designee of the
Grantee then serving on the Board of Directors of the Grantor, at any time that
the Grantee then beneficially owns less than 465,085 shares of Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations, mergers or other
changes in the corporate or capital structure of Grantor). The Grantee and the
Grantor agree to take such steps as may be necessary to give effect to this
Section 6(b) in a manner consistent with applicable law.
 
     7. Registration Rights.
 
     (a) In the event that the Grantee shall desire to sell any of the Shares
within two years after the purchase of such Shares pursuant hereto, and such
sale requires, in the opinion of counsel to the Grantee, which opinion shall be
reasonably satisfactory to the Grantor and its counsel, registration of such
Shares under the Securities Act, the Grantor will cooperate with the Grantee and
any underwriters in registering such Shares for resale, including, without
limitation, promptly filing a registration statement that complies with the
requirements of applicable federal and state securities laws and entering into
an underwriting agreement with such underwriters upon such terms and conditions
as are customarily contained in underwriting agreements with respect to
secondary distributions; provided that the Grantor shall not be required to have
declared effective more than two registration statements hereunder and shall be
entitled to delay the filing or effectiveness of any registration statement for
up to 90 days if the offering would, in the judgment of the Board of Directors
of the Grantor, require premature disclosure of any material corporate
development or otherwise interfere with or adversely affect any pending or
proposed offering of securities of the Grantor or any other material transaction
involving the Grantor.
 
     (b) If the Common Stock is registered pursuant to the provisions of this
Section 7, the Grantor agrees (i) to furnish copies of the registration
statement and the prospectus relating to the Shares covered thereby in such
numbers as the Grantee may from time to time reasonably request and (ii) if any
event shall occur as a result of which it becomes necessary to amend or
supplement any registration statement or prospectus, to prepare and file under
the applicable securities laws such amendments and supplements as may be
necessary to keep available for at least 90 days a prospectus covering the
Common Stock meeting the requirements of such securities laws, and to furnish
the Grantee such numbers of copies of the registration statement and prospectus
as amended or supplemented as may reasonably be requested. The Grantor shall
bear the cost of the registration, including, but not limited to, all
registration and filing fees, printing expenses, and fees and disbursements of
counsel and accountants for the Grantor, except that the Grantee shall pay the
fees and disbursements of its counsel, the underwriting fees and selling
commissions applicable to the shares of Common Stock sold by the Grantee. The
Grantor shall indemnify and hold harmless Grantee, its affiliates and its
officers and directors from and against any and all losses, claims, damages,
liabilities and expenses arising out of or based upon any statements contained
in, omissions or alleged omissions from, each registration statement filed
pursuant to this paragraph; provided, however, that this provision does not
apply to any loss, liability, claim, damage or expense to the extent it arises
out of any untrue statement or omission made in reliance upon and in conformity
with written information furnished to the Grantor by the Grantee, its affiliates
and its officers expressly for use in any registration statement (or any
amendment thereto) or any preliminary prospectus filed pursuant to this
paragraph. The Grantor shall also indemnify and hold harmless each underwriter
and each person who controls any underwriter within the meaning of either the
Securities Act or the Securities Exchange Act of 1934 against any and all
losses, claims, damages, liabilities and expenses arising out of or based upon
any statements contained in, omissions or alleged omissions from, each
registration statement filed pursuant to this paragraph; provided, however, that
this provision does not apply to any loss, liability, claim, damage or expense
to the extent it arises out of any untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Grantor by the
underwriters expressly for use in any registration statement (or any amendment
thereto) or any preliminary prospectus filed pursuant to this paragraph.
 
     8. Expenses. Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise specifically provided
herein.

<PAGE>   171
 
     9. Specific Performance. The Grantor acknowledges that if the Grantor fails
to perform any of its obligations under this Agreement immediate and irreparable
harm or injury would be caused to the Grantee for which money damages would not
be an adequate remedy. In such event, the Grantor agrees that the Grantee shall
have the right, in addition to any other rights it may have, to specific
performance of this Agreement. Accordingly, if the Grantee should institute an
action or proceeding seeking specific enforcement of the provisions hereof, the
Grantor hereby waives the claim or defense that the Grantee has an adequate
remedy at law and hereby agrees not to assert in any such action or proceeding
the claim or defense that such a remedy at law exists. The Grantor further
agrees to waive any requirements for the securing or posting of any bond in
connection with obtaining any such equitable relief.
 
     10. Notice. All notices, requests, demands and other communications
hereunder shall be deemed to have been duly given and made if in writing and if
served by personal delivery upon the party for whom it is intended or delivered
by certified mail, return receipt requested, or if sent by facsimile
transmission, upon receipt of oral confirmation that such transmission has been
received, to the person at the address set forth below, or such other address as

be binding upon the parties named herein and their respective successors and
assigns; provided, however, that such successors in interest or assigns shall
agree to be bound by the provisions of this Agreement. Nothing in this
Agreement, express or implied, is intended to confer upon any person other than
the Grantor or the Grantee, or their successors or assigns, any rights or
remedies under or by reason of this Agreement.
 
     12. Entire Agreement; Amendments. This Agreement, together with the Merger
Agreement and the other documents referred to therein, contains the entire
agreement between the parties hereto with respect to the subject matter hereof

<PAGE>   172
 
or written, with respect to such transactions. This Agreement may not be
changed, amended or modified orally, but may be changed only by an agreement in
writing signed by the party against whom any waiver, change, amendment,

     13. Assignment. No party to this Agreement may assign any of its rights or
obligations under this Agreement without the prior written consent of the other
party hereto, except that the Grantee may assign its rights and obligations
hereunder to any of its direct or indirect wholly owned subsidiaries, but no
such transfer shall relieve the Grantee of its obligations hereunder if such
transferee does not perform such obligations.
 
     14. Headings. The section headings herein are for convenience only and
shall not affect the construction of this Agreement.
 
     15. Counterparts. This Agreement may be executed in any number of

     16. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware (regardless of the laws that
might otherwise govern under applicable Delaware principles of conflicts of
law).
 
     17. Termination. The right to exercise the Option granted pursuant to this
Agreement shall terminate at the earlier of (i) the Effective Time (as defined
in the Merger Agreement), (ii) the date on which Grantee actually realizes a
Total Profit (as defined herein) of $3.2 million, (iii) 180 days after the
Merger Termination Date (the "Option Termination Date") or (iv) the Merger
Termination Date, in the event the Merger Agreement is terminated by the Grantor
pursuant to Section 9.1(g) thereof; provided that if the Option cannot be
exercised or the Shares cannot be delivered to Grantee upon such exercise
because the conditions set forth in Section 2(a) hereof have not yet been
satisfied, the Option Termination Date shall be extended until thirty days after
such impediment to exercise has been removed. All representations and warranties
contained in this Agreement shall survive delivery of and payment for the
Shares.
 
     18. Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.
 
     19. Public Announcement. The Grantee will consult with the Grantor and the
Grantor will consult with the Grantee before issuing any press release with
respect to the initial announcement of this Agreement, the Option or the
transactions contemplated hereby and neither party shall issue any such press
release prior to such consultation except as may be required by law or by
obligations pursuant to any listing agreement with any national securities
exchange or by the National Association of Securities Dealers, Inc.
 
     20. Right of First Refusal. If a Change in Control Event (as defined in
Section 20(e) below) has not then already occurred, and the Grantee, at any time
prior to the first anniversary of the Merger Termination Date, seeks to sell all
or any part of the Shares (i) in a transaction registered under the Securities
Act (other than in a registered public offering in which the underwriters are
instructed to achieve a broad public distribution) or (ii) in a transaction not
required to be registered under the Securities Act (other than in a transfer by
operation of law upon consummation of a merger), it shall give the Grantor (or a
designee of the Grantor) the opportunity, in the following manner, to purchase
such Shares:
 
     (a) The Grantee shall give notice to the Grantor in writing of its intent
to sell Shares (a "Disposition Notice"), specifying the number of Shares to be
sold, the price and, if applicable, the material terms of any agreement relating
thereto. For purposes of this Section 20, if the Disposition Notice is given
with respect to the sale of the Shares pursuant to a tender or exchange offer,
it shall be assumed that all Shares tendered will be accepted for payment. The
Disposition Notice may be given at any time, including prior to the giving of
any Stock Exercise Notice.
 
     (b) The Grantor or its designee shall have the right, exercisable by
written notice given to the Grantee within five business days after receipt of a
Disposition Notice (or, if applicable, in the case of a proposed sale
                                   Exhibit A-6
<PAGE>   173
 
pursuant to a tender or exchange offer for shares of Common Stock, by written
notice given to the Grantee at least two business days prior to the then
announced expiration date of such tender or exchange offer (the "Expiration
Date") if such Disposition Notice was given at least four business days prior to
such Expiration Date), to purchase all, but not less than all, of the Shares
specified in the Disposition Notice at the price set forth in the Disposition
Notice. If the purchase price specified in the Disposition Notice includes any
property other than cash, the purchase price to be paid by the Grantor shall be
an amount of cash equal to the sum of (i) the cash included in the purchase
price plus (ii) the fair market value of such other property at the date of the
Disposition Notice. If such other property consists of securities with an
existing public trading market, the average of the last sales prices for such
securities on the five trading days ending five days prior to the date of the
Disposition Notice shall be used as the fair market value of such property. If
such other property consists of something other than cash or securities with an
existing public trading market and at the time of the closing referred to in
paragraph (c) below, agreement on the value of such other property has not been
reached, the average of the closing prices for the Grantor's Common Stock on the
five trading days ending five days prior to the date of the Disposition Notice
shall be used as the per share purchase price; provided, however, that promptly
after the closing, the Grantee and the Grantor or its designee, as the case may
be, shall settle any additional amounts to be paid or returned as a result of
the determination of fair market value of such other property made by a
nationally recognized investment banking firm selected by the Grantor and
approved by the Grantee within 30 days of the closing. Such determination shall
be final and binding on all parties hereto. If, at the time of the purchase of
any Shares by the Grantor (or its designee) pursuant to this Section 20, a
tender or exchange offer is outstanding, then the Grantor (or its designee)
shall agree at the time of such purchase to promptly pay to Grantee from time to
time such additional amounts, if any, so that the consideration received by
Grantee with respect to each Share shall be equal to the highest price paid for
a share of Common Stock pursuant to such tender or exchange, or pursuant to any
other tender or exchange offer outstanding at any time such tender or exchange
offer is outstanding.
 
     (c) If the Grantor exercises its right of first refusal hereunder, the
closing of the purchase of the Shares with respect to which such right has been
exercised shall take place within five business days after the notice of such
exercise (or, if applicable, in the case of a tender or exchange offer, no later
than one business day prior to the expiration date of the offer if written
notice was given within the time set forth in the parenthetical in the first
sentence of paragraph (b) above); provided, however, that at any time prior to
the closing of the purchase of Shares hereunder, the Grantee may determine not
to sell the Shares and revoke the Disposition Notice and by so doing, cancel the
Grantor's right of first refusal with respect to the disposition in question.
The Grantor (or its designee) shall pay for the Shares in immediately available
funds.
 
     (d) If the Grantor does not exercise its right of first refusal hereunder
within the time specified for such exercise, the Grantee shall be free for 120
days following the expiration of such time for exercise to sell or enter into an
agreement to sell the Shares specified in the Disposition Notice, at the price
specified in the Disposition Notice or any price in excess thereof and otherwise
on substantially the same terms set forth in the Disposition Notice; provided,
that if such sale is not consummated within such 120-day period, then the
provisions of this Section 20 will again apply to the sale of such Shares.
 
     (e) For purposes of the Agreement, a "Change in Control Event" shall be
deemed to have occurred if (i) any person has a acquired beneficial ownership of
more than 50% (excluding the Shares) of the outstanding shares of Common Stock
or (ii) the Grantor shall have entered into an agreement, including without
limitation an agreement in principle, providing for a merger or other business
combination involving the Grantor or the acquisition of 20% or more of the
assets of the Grantor and its subsidiaries, taken as a whole.
 
     21. Profit Limitation.
 
     (a) Notwithstanding any other provision of this Agreement, in no event
shall the Grantee's Total Profit (as defined in Section 21(b) below) exceed $3.2
million and, if it otherwise would exceed such amount, the Grantee, at its sole
election, shall either (i) deliver to the Grantor for cancellation Shares
previously purchased by Grantee, (ii) pay cash or other consideration to the
Grantor or (iii) undertake any combination
 
                                   Exhibit A-7
<PAGE>   174
 
thereof, so that Grantee's Total Profit shall not exceed $3.2 million after
taking into account the foregoing actions.
 
     (b) As used herein, the term "Total Profit" shall mean the aggregate amount
(before taxes) of the following (i) the amount of cash, if any, received by
Grantee pursuant to Section 9.3(b) of the Merger Agreement, and (ii) (x) the net
cash amounts received by Grantee pursuant to the sale of Shares (or any other
securities into which such Shares are converted or exchanged) to any
unaffiliated party, less (y) the Grantee's purchase price for such Shares.
 
     IN WITNESS WHEREOF, the Company and Parent have caused this Agreement to be
signed by their respective officers thereunto duly authorized as of the date
first written above.

        NOTICE: THE PROXY PROVIDED HEREUNDER IS IRREVOCABLE FOR ITS TERM
 
                     VOTING AND IRREVOCABLE PROXY AGREEMENT
 
     THIS VOTING AND PROXY AGREEMENT ("Agreement") is made and entered into as
of June 29, 1998 between INFORMATION ADVANTAGE, INC., a Delaware corporation
("Parent"), and the undersigned shareholder (the "Shareholder") of IQ SOFTWARE
CORPORATION, a Georgia corporation (the "Company").
 
                                    RECITALS
 
     A. Concurrently with the execution of this Agreement, Parent, the Company
and IAC Merger Corp, a Georgia corporation and wholly-owned subsidiary of Parent
("Merger Sub"), have entered into an Agreement and Plan of Merger, dated June
29, 1998 (the "Merger Agreement"), which provides for the merger (the "Merger")
of Merger Sub with and into the Company, the cancellation of each outstanding
share of the Company's common stock.
 
     B. As a condition to its willingness to enter into the Merger Agreement,
Parent has requested that the Shareholder agree to certain matters regarding the
retention and voting of the Shares (as defined in Section 1.1 below) in
connection with the Merger.
 
     The parties agree as follows:
 
     1. Agreement to Retain Shares.
 
          1.1  Transfer and Encumbrance. The Shareholder agrees not to transfer,
     sell, exchange, pledge or otherwise dispose of or encumber (in each case,
     other than as a result of death or to affiliates; provided such affiliate
     agrees to be subject to the covenants, obligations and conditions set forth
     in this Agreement) any shares of capital stock of the Company owned or
     beneficially held by him (the "Shares"), or any New Shares (as defined in
     Section 1.2 below), or to make any offer or agreement relating thereto, at
     any time prior to the Expiration Date. As used herein, the term "Expiration
     Date" shall mean the earlier to occur of (i) such date and time as the
     Merger shall become effective in accordance with the terms and provisions
     of the Merger Agreement and (ii) the date on which the Merger Agreement
     shall be terminated in accordance with Article 9 thereof.
 
          1.2  Additional Purchases. The Shareholder agrees that any shares of
     capital stock of the Company that the Shareholder shall purchase or with
     respect to which the Shareholder shall otherwise acquire beneficial
     ownership after the execution of this Agreement and prior to the Expiration
     Date ("New Shares") shall be subject to the terms and conditions of this
     Agreement to the same extent as if they constituted Shares.
 
     2. Agreement to Vote Shares and Grant Proxy. At every meeting of the
shareholders of the Company called with respect to any of the following, and on
every action or approval by written consent of the shareholders of the Company
with respect to any of the following, the Shareholder agrees to vote the Shares
and any New Shares (i) in favor of approval of the Merger Agreement and the
Merger and any matter that could reasonably be expected to facilitate the
Merger, and (ii) against approval of any proposal made in opposition to or
competition with consummation of the Merger and against any merger,
consolidation, sale of assets, reorganization or recapitalization, with any
party other than with Parent and its affiliates and against any liquidation or
winding up of the Company (each of the foregoing is hereinafter referred to as
an "Opposing Proposal"). The Shareholder further agrees that the Shareholder
shall not, directly or indirectly, solicit or encourage any offer from any party
concerning the possible disposition of all or any substantial portion of the
Company's business, assets or capital stock. In the event the Company's board of
directors does not call a shareholder meeting to approve the Merger, the
Shareholder agrees to take all action necessary to call a shareholder meeting to
approve the Merger or to approve the Merger by written consent. In order to
 
                                   Exhibit B-1
<PAGE>   176
 
effectuate the foregoing, the Shareholder does hereby constitute and appoint
Parent, or any nominee of Parent, with full power of substitution, from the date
hereof to the Expiration Date, as its true and lawful proxy, for and in its
name, place and stead, including the right to sign its name (as shareholder) to
any consent, certificate or other document relating to the Company that the laws
of the State of Georgia may permit or require, to cause the Shares and any New
Shares to be voted in the manner contemplated by this Section 2. The parties and
proxies named above shall not exercise this proxy on any other matter except as
provided above. THE PARTIES ACKNOWLEDGE THAT THE PROXY PROVIDED FOR HERE IS
IRREVOCABLE AND COUPLED WITH AN INTEREST.
 
     3. Representations, Warranties and Covenants of the Shareholder. The
Shareholder represents, warrants and covenants to Parent as follows:
 
          3.1  Ownership of Shares. The Shareholder (together with such
     Shareholder's spouse, if applicable) (i) is the sole beneficial and record
     owner and holder of the Shares, which at the date hereof and at all times
     up until the Expiration Date, will be free and clear of any liens, claims,
     options, charges, security interests, equities, options, warrants, rights
     to purchase (including, without limitation, restrictions on rights of
     disposition other than those imposed by applicable securities laws), third
     party rights of any nature or other encumbrances, and (ii) does not own any
     shares of capital stock of the Company other than the Shares (excluding
     shares as to which Shareholder currently disclaims beneficial ownership).
 
          3.2  Authority; Due Execution. The Shareholder has full power and
     authority to make, enter into and carry out the terms of this Agreement.
     The Shareholder has duly executed and delivered this Agreement and
     (assuming the due authorization, execution and delivery of this Agreement
     by Parent) this Agreement constitutes a valid and binding obligation of the
     Shareholder.
 
          3.3  No Proxy Solicitations. The Shareholder will not, and will not
     permit any entity under such Shareholder's control to (i) solicit proxies
     or become a "participant" in a "solicitation," as such terms are defined in
     Regulation 14A under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), with respect to an Opposing Proposal or otherwise
     encourage or assist any party in taking or planning any action that would
     compete with, restrain or otherwise serve to interfere with or inhibit the
     timely consummation of the Merger in accordance with the terms of the

     acknowledge that Parent will be irreparably harmed and that there will be

     B. Upon the consummation of the Merger and in connection therewith, the
undersigned Securityholder will become the owner of shares of Common Stock of
Parent (the "Parent Shares").
 
     C. The parties to the Merger Agreement intend to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code") and intend to cause the Merger to qualify as a
"reorganization" under the provisions of Section 368(a)(1)(A) and Section
368(a)(2)(E) of the Code.
 
     D. The parties to the Merger Agreement intend to cause the Merger to be

     NOW, THEREFORE, in consideration of the premises and the mutual agreements,
provisions and covenants set forth in the Merger Agreement and in this
Affiliates Agreement, it is hereby agreed as follows:
 
     1. The undersigned Securityholder hereby agrees that:
 
        (a) The undersigned Securityholder may be deemed to be (but does not
hereby admit to be) an "affiliate" of the Company within the meaning of Rule 145
under the Securities Act of 1933, as amended (the "Securities Act"), and
Accounting Series Release No. 130, as amended, of the Securities and Exchange
Commission (the "SEC") ("Release No. 130").
 
        (b) The undersigned Securityholder will not sell, exchange, transfer,
pledge, dispose of or otherwise reduce the undersigned Securityholder's risk
relative to the Parent Shares or any part thereof until such time after the
Effective Time of the Merger as financial results covering at least thirty (30)

publication as soon as practicable. The undersigned will not, during the thirty
(30) day period prior to the Effective Time of the Merger as determined in
Parent's reasonable discretion, sell, exchange, transfer, pledge, dispose of or
otherwise reduce the undersigned Securityholder's risk relative to the Parent
Shares or any part thereof (including any disposition, within such period, of
Securityholder's shares of the Company's Common Stock).
 
        (c) Except with respect to the exchange of the Company Common Stock for
Parent Common Stock pursuant to the Merger, the undersigned has no current plan
or intent to engage in any sale of any Company capital stock (whether or not

Merger. The undersigned shall immediately notify Parent and the Company in
writing via facsimile of any sale of Company capital stock by the undersigned
on, or prior to, the Merger.

<PAGE>   180
 
        (d) Subject to paragraphs (b) and (c) of this Section 1, the undersigned

otherwise dispose of any of the Parent Shares unless at that time either:
 
           (i) such transaction is permitted pursuant to the provisions of Rule
145(d) under the Securities Act;
 
           (ii) counsel representing the undersigned Securityholder, reasonably
satisfactory to Parent, shall have advised Parent in a written opinion letter
reasonably satisfactory to Parent and Parent's counsel and upon which Parent and
its counsel may rely, that no registration under the Securities Act is required
in connection with the proposed sale, transfer or other disposition;
 
           (iii) a registration statement under the Securities Act covering the
Parent Shares proposed to be sold, transferred or otherwise disposed of,
describing the manner and terms of the proposed sale, transfer or other
disposition, and containing a current prospectus, is filed with the SEC and made
effective under the Securities Act; or
 
           (iv) an authorized representative of the SEC shall have rendered
written advice to the undersigned Securityholder (sought by the undersigned
Securityholder or counsel to the undersigned Securityholder, with a copy thereof
and of all other related communications delivered to Parent) to the effect that
the SEC will take no action, or that the staff of the SEC will not recommend
that the SEC take action, with respect to the proposed offer, sale, exchange,
transfer, pledge or other disposition if consummated.
 
        (e) All certificates representing the Parent Shares deliverable to the
undersigned Securityholder pursuant to the Merger Agreement and in connection
with the Merger and any certificates subsequently issued with respect thereto or
in substitution therefor shall, unless one or more of the alternative conditions
set forth in the subparagraphs of paragraph (d) of this Section 1 shall have
occurred, bear a legend substantially as follows:
 
           "The shares represented by this certificate may not be offered, sold,
           exchanged, transferred, pledged or otherwise disposed of except in
           accordance with the requirements of the Securities Act of 1933, as
           amended, and the other conditions specified in that certain
           Affiliates Agreement dated                     , 1998, a copy of
           which Affiliates Agreement may be inspected by the holder of this
           certificate at the offices of Parent, or Parent will furnish, without
           charge, a copy thereof to the holder of this certificate upon written
           request therefor."
 
Parent, at its discretion, may cause stop transfer orders to be placed with its
transfer agent with respect to the certificates for the Parent Shares but not as
to the certificates for any part of the Parent Shares as to which said legend is
no longer appropriate when one or more of the alternative conditions set forth
in the subparagraphs of paragraph (d) of this Section 1 shall have occurred.
 
        (f) The undersigned Securityholder will observe and comply with the
Securities Act and the general rules and regulations thereunder, as now in
effect and as from time to time amended and including those hereafter enacted or
promulgated, in connection with any offer, sale, exchange, transfer, pledge or
other disposition of the Parent Shares or any part thereof.
 
     2. Reports. From and after the Effective Time of the Merger and for so long
as necessary in order to permit the undersigned Securityholder to sell the
Parent Shares pursuant to Rule 145 and, to the extent applicable, Rule 144 under
the Securities Act, Parent will file on a timely basis all reports required to
be filed by it pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934, referred to in paragraph (c)(1) of Rule 144 under the Securities Act (or,
if applicable, Parent will make publicly available the information regarding
itself referred to in paragraph (c)(2) of Rule 144), in order to permit the
undersigned Securityholder to sell, pursuant to the terms and conditions of Rule
145 and the applicable provisions of Rule 144, the Parent Shares.

of any provision of this Affiliates Agreement shall be effective unless in
writing.

               WRITTEN OPINION OF BANCAMERICA ROBERTSON STEPHENS
 
                                 June 28, 1998
 
Board of Directors
Information Advantage, Inc.
7905 Golden Triangle Drive
Eden Prairie, MN 55344-7227
 
Members of the Board:
 
     You have asked our opinion with respect to the fairness to Information
Advantage, Inc. ("IACO"), from a financial point of view, as of the date hereof,
of the Exchange Ratio (as defined below), in the proposed merger of IQ Software
Corp. ("IQSW") with and into a wholly owned subsidiary of IACO ("Merger Sub")
pursuant to the draft Agreement and Plan of Merger (the "Agreement") that we
have reviewed, by and among IACO, IQSW and Merger Sub. As more specifically set
forth in the Agreement, and subject to the terms thereof, Merger Sub will merge
(the "Merger") with and into IQSW, and each issued and outstanding share of
common stock, par value $0.00033 per share ("IQSW Common Stock"), of IQSW will
be converted into the right to receive 1.96 shares (the "Exchange Ratio") of
common stock, par value $.01 per share ("IACO Common Stock"), of IACO. The
Merger is intended to qualify as a tax-free reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended, and to be
accounted for as a "pooling of interests." The terms and conditions of the
Merger are set out more fully in the Agreement.
 
     For purposes of this opinion we have: (i) reviewed certain financial
information with respect to IQSW and IACO furnished to us by IACO and IQSW,
including certain internal financial analyses and forecasts prepared by the
management of IQSW; (ii) reviewed certain publicly available information
relating to IACO and IQSW, including their respective stock price and trading
histories; (iii) held discussions with the managements of IACO and IQSW
concerning the businesses, past and current business operations, financial
condition and future prospects of both companies, independently and combined;
(iv) reviewed the financial terms and conditions set forth in the Agreement; (v)
reviewed the trading prices of securities of certain publicly traded companies
that we deemed comparable to IQSW; (vi) prepared discounted cash flow analyses
of IQSW; (vii) compared the financial terms of the Transaction with other
transactions that we deemed relevant; and (viii) made such other studies and
inquiries, and reviewed such other data, as we deemed relevant. We did not have
access to any non-public information regarding the shareholder class action
litigation concerning the alleged failure of IQSW to disclose the risks and
liabilities assumed by the Company in connection with the transition of its
sales force from an inside telesales model to an outside field-based model, and
BARS has assumed, with IACO's consent, that the pending and any future
litigation against IQSW would not have a material effect on IQSW.
 
     In our review and analysis, and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information provided to us or publicly available and have neither attempted
independently to verify nor assumed any responsibility for verifying any of such
information. Furthermore, we did not obtain any independent appraisal of the
properties, assets or liabilities (contingent or otherwise) of IACO or IQSW or
of any of their subsidiaries, nor were we furnished with any such evaluations or
appraisals. With respect to the financial and operating forecasts (and the
assumptions and bases thereof) of IACO and IQSW that we have reviewed, we have
assumed that such forecasts have been reasonably prepared in good faith on the
basis of reasonable assumptions, reflect the best available estimates and
judgments of IACO's management, and that such projections and forecasts will be
realized in the amounts and in the time periods currently estimated by the
management of IACO. Further, we have assumed that the historical financial
statements of IACO and IQSW that we have reviewed have been prepared in
accordance with U.S. generally accepted accounting principles. We have also
assumed that the Transaction will be consummated upon the terms set forth in the
Agreement without material alteration thereof and that the Transaction will
 
                                       B-1
<PAGE>   188
 
qualify for the tax and accounting treatment described above. We have relied as
to all legal matters relevant to rendering our opinion on the advice of counsel.
 
     This opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect this
opinion and that we disclaim any undertaking or obligation to advise any person
of any change in any fact or matter affecting this opinion which may come or be
brought to our attention after the date of this opinion. Our opinion is limited
to the fairness, from a financial point of view to IACO of the Exchange Ratio.
We do not express any opinion as to the value of any employee agreements or
arrangements entered into in connection with the Agreement or the Merger, nor do
we express any opinion as to the price at which the shares of common stock of
IACO that are to be issued pursuant to the Merger will be traded in the future.
Our opinion does not address the relative merits of the Merger and the other
business strategies that the Board of Directors of IACO has considered or may be
considering, nor does it address the Board's business decision to proceed with
the Merger process.
 
     Our opinion is directed to the Board of Directors of IACO and is not
intended to be and does not constitute a recommendation to any stockholder of
IACO as to how such shareholder should vote on the Merger. This opinion may be
included in a proxy or registration statement of IACO distributed in connection
with the Merger, provided that this opinion is reproduced therein in full and
any description of, or reference to, this opinion therein is in a form and
substance acceptable to us and our legal counsel. Except as provided in the
previous sentence, this opinion shall not be reproduced, summarized, described
or referred to, or furnished to any party, without our prior written consent.
 
     In the ordinary course of business, we may actively trade the securities of
IACO and IQSW for our own account or for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.
We have acted as financial advisor to IACO in connection with the Merger, for
which a portion of our fee is due and payable contingent upon the closing of the
Merger. We have also led-managed an underwriting conducted by IACO within the
last 12 months.
 
     Based upon and subject to the foregoing considerations, it is our opinion,
that, as of the date hereof, the Exchange Ratio is fair to IACO from a financial
point of view.
 
                                            Very truly yours,
 
                                            BANCAMERICA ROBERTSON STEPHENS

                     WRITTEN OPINION OF FIRST ALBANY CORP.
 
                                 June 26, 1998
 
Board of Directors
IQ Software Corporation
3295 River Exchange Drive
Suite 550
Norcross, GA 30092-4220
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to the stockholders of IQ Software Corporation (the "Company") of the
merger (the "Merger") with and into Information Advantage, Inc. ("IACO"), which
will be the surviving entity, pursuant to an Agreement and Plan of Merger
between the Company and IACO (the "Agreement"). Pursuant to the Merger and as
more fully described in the Agreement, each issued and outstanding share of
Company Common Stock shall be converted into the right to receive 1.96 shares of
IACO Common Stock.
 
     First Albany Corporation ("First Albany"), as a customary part of its
investment banking business, is engaged on a regular basis in the valuation of
businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, private placements and valuations for corporate,
estate and other purposes. We regularly publish research reports regarding
various industry sectors.
 
     In connection with and in preparation for rendering this opinion, we have
reviewed, analyzed and relied upon certain information bearing upon the
financial and operating condition of the Company and IACO, including: the
Agreement; publicly available financial statements and related information of
the Company and IACO, as of and for the fiscal years ended January 31, 1998,
1997, and 1996 and the quarter ended April 30, 1998; publicly available
information concerning the historical prices at which the common stock of the
Company and IACO have been transferred; and other financial information
concerning the business and operations of the Company and IACO made available to
us from the published sources and from the Company and IACO, including certain
internal financial and operating budgets, analyses and forecasts of the Company
and IACO prepared by their respective managements. We have also discussed with
members of the senior management of the Company and IACO the past and current
business operations, financial condition and future prospects of the Company and
IACO, as well as other matters believed to be relevant to our analysis. Further,
we considered such other information, financial studies, analyses and
investigations, and financial, economic and market criteria which we deemed
relevant to our analysis including, to the extent publicly available, the
financial terms of comparable transactions. We have also compared the Company
and IACO from a financial point of view with certain other companies in the
business intelligence industry which we have deemed to be relevant. Our opinion
is based on market, economic and other conditions as they exist and can be
evaluated by us on the date hereof.
 
     In conducting our review and arriving at our opinion, we have relied upon
and assumed the accuracy and completeness of all of the financial and other
information provided to us by the Company or IACO, or otherwise publicly
available, and have assumed that there have been no material changes in the
Company's or IACO's business operations, financial condition or prospects since
the respective dates of such information. With respect to the financial
forecasts for the Company and IACO provided to us by their respective senior
managements, upon their advice and with your consent, we have assumed for the
purposes of our opinion that the forecasts have been reasonably prepared on
basis reflecting the best available estimates and judgments of their respective
managements at the time of preparation as to future financial performance of the
Company and IACO, and that they provide a reasonable basis upon which we can
form our opinion. We have relied on advice of counsel to the Company as to all
legal matters with respect to the Company, the Merger and the
 
                                       C-1
<PAGE>   190
 
Agreement, including the legal status of litigation involving the Company. We
have not independently verified this information, nor have we had such
information verified. For the purposes of rendering this opinion, we have not
conducted a physical inspection of any of the assets, properties or facilities
of the Company or IACO, nor have we made or obtained any independent evaluation
or appraisals of any such assets, properties or facilities. Further, you have
informed us and we have assumed that the Merger will be accounted for on a
pooling of interests basis under generally accepted accounting principles.
 
     We have further assumed with your consent that the Merger will be
consummated in accordance with the terms described in the Agreement, without any
further amendments thereto, and without waiver by the Company of any of the
conditions to its obligations thereunder. We have also assumed that the Merger
will be consummating in a matter that complies in all respects with the
applicable provisions of the Securities Act of 1933, as amended (the "Securities
Act"), the Securities Exchange Act of 1934, as amended, and all other applicable
federal and state statutes, rules and regulations.
 
     We have not been asked to consider, and this opinion does not address, the
relative merits of the Merger as compared to any alternative business strategy
that may exist for the Company. Our opinion has been prepared solely for the
benefit of the Board of Directors of the Company for use in its consideration of
the Merger and does not constitute a recommendation to any shareholder of the
Company as to how such shareholder should vote on the Merger. This opinion may
not be used or referred to by the Company, or quoted or disclosed to any person
in any manner, without our prior written consent which is hereby given to the
inclusion of this opinion in the Joint Proxy Statement/Prospectus to be filed
with the Securities and Exchange Commission in connection with the Merger. In
furnishing this opinion, we do not admit that we are experts within the meaning
of the term "experts" as used in the Securities Act and the rules and
regulations promulgated thereunder, nor to we admit that this opinion
constitutes a report or valuation within the meaning of Section 11 of the
Securities Act.
 
     In connection with the Merger, we are acting as financial advisor to the
Company and, in connection with that service, will receive a financial advisory
fee that is conditioned on the successful completion of the Merger. We will also
receive a fee for rendering this opinion. We have acted as a market maker for
the Company's common stock and for IACO's common stock and have otherwise
engaged in transactions in the Company's common stock and in IACO's common stock
for our own account and for the accounts of our clients. Accordingly, at any
time, we may have a long or short position in such securities.
 
     We may, from time to time, have a long or short position in, and buy or
sell, the Company's common stock for our own account and for the accounts of our
customers.
 
     Based upon and subject to the foregoing, it is our opinion that the
consideration to be received by the stockholders of the Company pursuant to the
Merger is fair to such stockholders from a financial point of view, as the date
hereof.
 
                                          Very truly yours,
 
                                          FIRST ALBANY CORPORATION

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the DGCL empowers a Delaware corporation to indemnify any
persons who are, or are threatened to be made, parties to any threatened,
pending or completed legal action, suit or proceedings, whether civil, criminal,
administrative or investigative (other than action by or in the right of such
corporation), by reason of the fact that such person was an officer or director
of such corporation, or is or was serving at the request of such corporation as
a director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that such officer or
director acted in good faith and in a manner he reasonably believed to be in or
not opposed to the corporation's best interests, and, for criminal proceedings,
had no reasonable cause to believe his conduct was illegal. A Delaware
corporation may indemnify officers and directors in an action by or in the right
of the corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the corporation in the performance of his duty. Where an officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses which
such officer or director actually and reasonably incurred.
 
     In accordance with the DGCL, the Registrant's Restated Certificate of
Incorporation contains a provision to limit the personal liability of the
directors of the Registrant for violations of their fiduciary duty. This
provision eliminates each director's liability to the Registrant or its
stockholders for monetary damages except (i) for any breach of the director's
duty of loyalty to the Registrant or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL providing for liability of
directors for unlawful payment of dividends or unlawful stock purchases or
redemptions, or (iv) for any transaction from which a director derived an
improper personal benefit. The effect of this provision is to eliminate the
personal liability of directors for monetary damages for actions involving a
breach of their fiduciary duty of care, including any such actions involving
gross negligence.
 
     Article IX of the Registrant's Restated Certificate of Incorporation and
Article VII, Section 6 of Registrant's Amended and Restated Bylaws provide for
indemnification of the officers and directors of the Registrant to the fullest
extent permitted by applicable law.
 
     The Registrant has entered into indemnification agreements with each
director and executive officer which provide indemnification to such directors
and executive officers under certain circumstances for acts or omissions which
may not be covered by directors' and officers' liability insurance.

ITEM 22. UNDERTAKINGS
 
     Registrant hereby undertakes as follows: that prior to any public
reoffering of the securities registered hereunder through use of a prospectus
which is a part of this Registration Statement, by any person or party who is
deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering prospectus will contain the information called
for by the applicable registration form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other items of the applicable form.
 
     Registrant undertakes that every prospectus (i) that is filed pursuant to
the immediately preceding paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of Registrant
pursuant to the foregoing provisions, or otherwise, Registrant has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Registrant of expenses
incurred or paid by a director, officer or controlling person of Registrant in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, Registrant will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.

     Re:  Registration Statement on Form S-4
          ----------------------------------

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-4 as filed by
Information Advantage, Inc. (the "Company") with the Securities and Exchange
Commission on August 21, 1998, as thereafter amended or supplemented (the
"Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of shares of the Company's Common Stock (the
"Shares") to be issued to the stockholders of IQ Software Corporation ("IQ") in
connection with the merger of a wholly owned subsidiary of the Company with and
into IQ. As your legal counsel, we have examined the proceedings taken and are
familiar with the proceedings proposed to be taken by you in connection with the
sale and issuance of the Shares.

     It is our opinion that, upon conclusion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities laws of
the various states where required, the Shares, when issued and sold in the
manner described in the Registration Statement, will be legally and validly
issued, fully paid and non-assessable.

     We consent to the use of this opinion as an exhibit to said Registration
Statement, and further consent to the use of our name wherever appearing in said
Registration Statement, including the prospectus constituting a part thereof,
and in any amendment or supplement thereto.

                                   Very truly yours,

Ladies and Gentlemen:

     This opinion is being delivered to you for the purpose of satisfying
Section 6.1(c) of the Amended and Restated Agreement and Plan of Merger, dated
as of June 29, 1998 (the "Merger Agreement") among Information Advantage, Inc.,
a Delaware corporation ("IA"), its wholly-owned subsidiary, IAC Merger Corp., a
Delaware corporation ("Merger Sub"), and IQ Software Corporation, a Georgia
corporation ("IQ"). Pursuant to the Merger Agreement, Merger Sub will merge with
and into IQ (the "Merger"), and IQ will become a wholly-owned subsidiary of IA.

     Except as otherwise provided, capitalized terms referred to herein have the
meanings set forth in the Merger Agreement. All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

     We have acted as legal counsel to IA in connection with the Merger. As
such, and for the purpose of rendering this opinion, we have examined and are
relying (or will rely) upon (without any independent investigation or review
thereof) the truth and accuracy, at all relevant times, of the statements,
covenants, representations and warranties contained in the following documents
(including all schedules and exhibits thereto):

     1. The Merger Agreement (including Exhibits);

     2. Representations made to us by IQ in a letter of even date;

     3. Representations made to us by IA and Merger Sub in a letter of even
date;

     5. The Securities and Exchange Commission Registration Statement on Form
S-4 and related Exhibits thereto relating to the Merger Agreement; and

     6. Such other instruments and documents related to the formation,
organization and operation of IA, IQ and Merger Sub or to the consummation of
the Merger and the transactions contemplated thereby as we have deemed necessary
or appropriate.

     In connection with rendering this opinion, we have assumed that:

submitted to us as copies conform to the original documents, and there has been
(or will be by the Effective Time of the Merger) due execution and delivery of
all documents where due execution and delivery are prerequisites to
effectiveness thereof.

     2. Any representation or statement made "to the knowledge of" or otherwise
similarly qualified is correct without such qualification and all statements and
representations, whether or not qualified, will remain true through the
Effective Time. As to all matters in which a person or entity making a
representation has represented that such person or entity either is not a party
to, does not have, or is not aware of any plan, intention, understanding or
agreement to take an action, there is in fact no plan, intention, understanding
or agreement and such action will not be taken.

     3. The Merger will be consummated pursuant to the Merger Agreement and will
be effective under the laws of the state of Delaware and Georgia.

     4. No IQ shareholder has guaranteed or will guarantee any IQ indebtedness
outstanding during the period immediately prior to the Merger, and at all
relevant times, including as of the Effective Time of the Merger, (i) no
outstanding indebtedness of IQ, IA or Merger Sub has or will represent equity
for tax purposes; (ii) no outstanding equity of IQ, IA or Merger Sub has or will
represent indebtedness for tax purposes; and (iii) no outstanding security,
instrument, agreement or arrangement that provides for, contains, or represents
either a right to acquire IQ stock or to share in the appreciation thereof
constitutes or will constitute "stock" for purposes of Section 368(c) of the
Code.

     5. Counsel for IQ, Miller & Martin LLP, has, pursuant to Section 6.1(c) of
the Agreement, delivered an opinion to the effect that, for federal income tax
purposes, the Merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Code.

     6. Following the Merger, IQ will hold "substantially all" of its and Merger
Sub's properties within the meaning of Section 368(a)(2)(E)(i) of the Code and
the regulations promulgated thereunder and will continue its historic business
or use a significant portion of its historic assets in a business.

     7. To the extent any expenses relating to the Merger (or the "plan of
reorganization" within the meaning of Treas. Reg. ss.1.368-1(c) with respect to

incurring party, such expenses will be within the guidelines established in
Revenue Ruling 73-54, 1973-1 C.B. 187; any expenses paid on behalf of IQ
shareholders will not exceed one percent (1%) of the total consideration that

     8. IQ, IA and Merger Sub will report the Merger on their respective U.S.
federal income tax returns in a manner consistent with the opinion set forth
below and will comply with all reporting obligations set forth in the Code and
the Treasury Regulation promulgated thereunder.

     Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, we are
of the opinion that, if the Merger is consummated in accordance with the
provisions of the Merger Agreement (and without any waiver, breach or amendment
of any provisions thereof), for federal income tax purposes the Merger will
constitute a "reorganization" within the meaning of Section 368(a) of the Code.

     In addition to the assumptions set forth above, this opinion is subject to
the exceptions, limitations and qualifications set forth below.

     1. This opinion represents and is based upon our best judgment regarding
the application of federal income tax laws arising under the Code, existing
judicial decisions, administrative regulations and published rulings and
procedures. Our opinion is not binding upon the Internal Revenue Service or the
courts, and there is no assurance that the Internal Revenue Service will not
successfully assert a contrary position. Furthermore, no assurance can be given
that future legislative, judicial or administrative changes, on either a
prospective or retroactive basis, would not adversely affect the accuracy of the
conclusions stated herein. Nevertheless, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
federal income tax laws.

     2. This opinion addresses only the classification of the Merger as a
reorganization under Section 368(a) of the Code, and does not address any other
federal, state, local or foreign tax consequences that may result from the
Merger or any other transaction (including any transaction undertaken in
connection with the Merger). We express no opinion regarding the tax
consequences of the Merger to shareholders of IQ that are subject special tax
rules, and we express no opinion regarding the tax consequences of the Merger
arising in connection with the ownership of options or warrants for IQ stock.

     3. No opinion is expressed as to any transaction other than the Merger as
described in the Merger Agreement or to any transaction whatsoever, including
the Merger, if all the transactions described in the Merger Agreement are not
consummated in accordance with the terms of such Merger Agreement and without
waiver or breach of any material provision thereof or if all of the
representations, warranties, statements and assumptions upon which we relied are

not true and accurate through the Effective Time and at all relevant times
thereafter. In the event any one of the statements, representations, warranties
or assumptions upon which we have relied to issue this opinion is incorrect, our
opinion might be adversely affected and may not be relied upon.

     4. This opinion has been delivered to you solely for purposes of satisfying
Section 6.1(c) of the Merger Agreement; it may not be relied upon for any other
purpose (including, without limitation, satisfying any conditions in the
Agreement) or by any other person or entity, and may not be made available to
any other person or entity without our prior written consent.


                                Very truly yours,

IQ SOFTWARE CORPORATION
3295 River Exchange Drive
Suite 550
Norcross, GA  30092

Attention:  Board of Directors

            Re:  Tax Opinion for the Merger Transaction Involving IQ Software
                 Corporation, Information Advantage, Inc. and IAC Merger Corp.

Ladies and Gentlemen:

               We have been requested to render this opinion concerning certain
matters of U.S. federal income tax law in connection with the proposed merger
(the "MERGER") involving IQ Software Corporation, a corporation organized and
existing under the laws of the State of Georgia ("IQ"), Information Advantage,
Inc., a corporation organized under the laws of the State of Delaware ("IA"),
and IAC Merger Corp., a new corporation organized and existing under the laws of
the State of Georgia as a wholly owned subsidiary of IA ("NEWCO").

               The Merger is structured as a statutory merger of Newco with and
into IQ, with IQ surviving the merger and becoming a wholly-owned subsidiary of
IA, all pursuant to the applicable corporate laws of the States of Georgia and
Delaware in accordance with the Amended and Restated Agreement and Plan of
Merger by and among IQ, IA and Newco, dated as of June 29, 1998, and exhibits
thereto (collectively, the "MERGER AGREEMENT"). Except as otherwise indicated,
capitalized terms used herein have the meanings set forth in the Merger
Agreement. All section references, unless otherwise indicated, are to the
Internal Revenue Code of 1986, as amended (the "CODE").

               We have acted as legal counsel to IQ in connection with the
Merger. As such, and for the purpose of rendering this opinion, we have examined
and are relying upon (without any independent investigation or review thereof)
the truth and accuracy, at all relevant times, of the 



<PAGE>   2

statements, covenants, representations and warranties contained in the following
documents (including all schedules and exhibits thereto):

               (1) The Merger Agreement;

               (2) An Officer's Tax Certificate of IQ dated ____ __, 1998,
        signed by an authorized officer of IQ and delivered to us from IQ and
        incorporated herein by reference; and

               (3) An Officer's Tax Certificate of IA and Newco dated ____ __,
        1998, signed by an authorized officer of each of IA and Newco and
        delivered to us from IA and Newco and incorporated herein by reference.

               In addition, we have reviewed such other instruments and
documents related to the formation, organization and operation of IQ, IA and
Newco or the consummation of the Merger and the transactions contemplated
thereby as we have deemed necessary or appropriate.

               In connection with rendering this opinion, we have assumed or
obtained representations and are relying thereon (without any independent
investigation or review thereof) that:

               (1) Original documents (including signature) are authentic;
        documents submitted to us as copies conform to the original documents,
        and there has been (or will be by the Effective Time of the Merger) due
        execution and delivery of all documents where due execution and delivery
        are prerequisites to the effectiveness thereof;

               (2) All participants in the Merger possess adequate legal
        capacity;

               (3) Any representation or statement referred to above made "to
        the knowledge of" or "to the belief of" or otherwise similarly qualified
        is correct without such qualification, and all statements and
        representations, whether or not qualified are true and will remain true
        through the Effective Date;

               (4) The Merger will be consummated pursuant to the Merger
        Agreement and will be effective under the laws of the states of Georgia
        and Delaware;

               (5) IA has no plan or intention directly or indirectly (through
        one or more related parties) to reacquire any of its voting common stock
        issued in the Merger. For these purposes, "RELATED PARTIES" include
        corporations that are members of the same affiliated group as defined in
        Section 1504 of the Code (determined without regard to Section 1504(b)
        of the Code), or two corporations if the first corporation purchases the
        stock of the second corporation in a transaction which would be treated
        as a distribution in redemption of the stock of the first corporation
        under Section 304(a)(2) of the Code 



                                       2
<PAGE>   3

        (determined without regard to Treas. Reg. Section 1.1502-80(b)). In
        addition, a corporation will be treated as related to another
        corporation if such relationship exists immediately before or
        immediately after the acquisition of the stock involved. Moreover, a
        corporation, other than IQ or a person related to IQ, will be treated as
        related to IA if the relationship is created in connection with the
        Merger.

               (6) Following the Merger, IQ will hold "substantially all" of its
        and Newco's assets within the meaning of Section 368(a)(2)(E)(i) of the
        Code and the Treasury Regulations promulgated thereunder and will
        continue its historic business or use a significant portion of its
        historic business assets in a business;

               (7) To the extent any expenses relating to the Merger (or the
        "plan of reorganization" within the meaning of Treas. Reg. Section
        1.368-1(c) with respect to the Merger) are funded directly or indirectly
        by a party other than the incurring party, such expenses will be within
        the guidelines established in Revenue Ruling 73-54, 1973-1 C.B.
        187;

               (8) No IQ stockholder has guaranteed or will guarantee any IQ
        indebtedness outstanding during the period immediately prior to the
        Merger, and at all relevant times prior to and including the Effective
        Date: (i) no outstanding indebtedness of IQ, IA, or Newco has
        represented or will represent equity for tax purposes; (ii) no
        outstanding equity of IQ, IA, or Newco has represented or will represent
        indebtedness for tax purposes; and (iii) no outstanding security,
        instrument, agreement or arrangement that provides for, contains, or
        represents either a right to acquire IQ capital stock (or to share in
        the appreciation thereof) constitutes or will constitute "stock" for
        purposes of Section 368(c) of the Code;

               (9) None of IQ, IA or Newco is, or will be at the time of the
        Merger, an investment company as defined in Section 368(a)(2)(F) of the
        Code; and

               (10) IQ, IA and Newco will report the Merger on their respective
        U.S. federal income tax returns in a manner consistent with the opinion
        set forth below and will comply with all reporting obligations set forth
        in the Code and the Treasury Regulations promulgated thereunder.

               In addition to the above, our opinion is conditioned on the
delivery of an opinion of counsel, substantially identical to this opinion, to
IA from Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP and that
such opinion will not be withdrawn prior to the Effective Date.

               Based on the foregoing documents, materials, assumptions and
information, and subject to the qualifications and assumptions set forth herein,
we are of the opinion that, if the Merger is consummated in accordance with the
provisions of the Merger Agreement (and 



                                       3
<PAGE>   4

without any waiver, breach of amendment of any of the provisions thereof), the
Merger will be a "reorganization" for federal income tax purposes within the
meaning of Section 368(a) of the Code.

               Our opinion set forth above is based on the existing provisions
of the Code, Treasury Regulations (including Temporary Treasury Regulations)
promulgated under the Code, published Revenue Rulings, Revenue Procedures and
other announcements of the Internal Revenue Service (the "SERVICE") and existing
court decisions, any of which could be changed at any time. Any such changes
might be retroactive with respect to transactions entered into prior to the date
of such changes and could significantly modify the opinion set forth above.
Nevertheless, we undertake no responsibility to advise you of any subsequent
developments in the application, operation or interpretation of the U.S. federal
income tax laws.

               Our opinion concerning certain of the U.S. federal tax
consequences of the Merger is limited to the specific U.S. federal tax
consequences presented above. No opinion is expressed as to any transaction
other than the Merger, including any transaction undertaken in connection with
the Merger. In addition, this opinion does not address any estate, gift, state,
local or foreign tax consequences that may result from the Merger. In
particular, we express no opinion regarding: (i) the amount, existence, or
availability after the Merger, of any of the U.S. federal income tax attributes
of IQ, IA or Newco; (ii) any transaction in which IQ common stock is acquired or
IA common stock is disposed of other than pursuant to the Merger; (iii) the
potential application of the "disqualifying disposition" rules of Section 421 of
the Code to dispositions of IQ common stock; (iv) the effects of the Merger and
IA's assumption of outstanding options to acquire IQ stock on the holders of
such options under any IQ employee stock option or stock purchase plan,
respectively; (v) the effects of the Merger on any IQ stock acquired by the
holder subject to the provision of Section 83(a) of the Code; (vi) the effects
of the Merger on any payment which is or may be subject to the provisions of
Section 280G of the Code; (vii) the application of the collapsible corporation
provisions of Section 341 of the Code to IQ, IA or Newco as a result of the
Merger; (viii) the application of the alternative minimum tax provisions
contained in the Code; (ix) the effects of the Merger on any IQ stock acquired
or held as part of a "straddle," "conversion transaction," "hedging
transaction," or other risk reduction transaction; and (x) any special tax
consequences applicable to insurance companies, securities dealers, financial
institutions, tax-exempt organizations or foreign persons.

               No ruling has been or will be requested from the Service
concerning the U.S. federal income tax consequences of the Merger. In reviewing
this opinion, you should be aware that the opinion set forth above represents
our conclusions regarding the application of existing U.S. federal income tax
law to the instant transaction. If the facts vary from those relied upon
(including if any representations, covenant, warranty or assumption upon which
we have relied is inaccurate, incomplete, breached or ineffective), our opinion
contained herein could be inapplicable. You should be aware that an opinion of
counsel represents only counsel's best legal judgment, and has no binding effect
or official status of any kind, and that no assurance can be 



                                       4
<PAGE>   5

given that contrary positions may not be taken by the Service or that a court
considering the issues would not hold otherwise.

               This opinion is being delivered solely for the purpose of
satisfying the condition set forth in Section 8.2(f) of the Merger Agreement.
This opinion may not otherwise be relied upon or utilized for any other purpose
or by any other person or entity, and may not be made available to any other
person or entity, without our prior written consent.

               We hereby consent to the reference to us under the heading "The
Merger -- Certain Federal Income Tax Consequences" in the Proxy
Statement-Prospectus pertaining to the Merger and to the filing of this opinion
as an exhibit to the related Registration Statement on Form S-4 filed with the
Securities and Exchange Commission. In giving this consent, we do not hereby
admit that we are within the category of persons whose consent is required under
Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder.



                                                  Very truly yours,

Reseller accepts such appointment.

      (b)   IQSC will license a reasonable number of copies of the Software to
the Reseller at no charge for its own internal use, including for demonstration
purposes.

      (c)   The appointment contained herein does not constitute a grant of any
specific territory or geographic area. IQSC reserves the right to market and
solicit sales directly and indirectly through dealers and distributors, and
through any other channel of distribution at any time and from time to time, as
it determines in its sole judgment, and Reseller will not be entitled


                                       1
<PAGE>   2
to any commission, discount or any other compensation with respect to or on
account of such sales.

personnel.

     (g)  All activities of the Reseller pursuant to its obligations under this
Agreement shall be undertaken at the sole cost and expense of the Reseller.

     (h)  The Reseller shall prepare and submit to IQSC monthly marketing and
sales reports within fifteen (15) days after the end of each calendar month in
such form and with such information as IQSC may reasonably request from time to
time.

     (i)  The Reseller shall obtain orders on contracts designated by IQSC,
which orders are not valid or binding until accepted by IQSC in its reasonable
discretion. A contract accepted by IQSC shall hereafter be referred to as an
"Accepted Contract." The Reseller shall make no commitments, written or oral,
regarding the Software or the terms and conditions of the license thereof that
are not specifically set forth in the IQSC's then standard license agreement
("License Agreement") or as specifically authorized in writing by IQSC.

     (j)  The Reseller agrees to indemnify and hold harmless IQSC from any loss
or damages claimed by reason of or arising out of any alleged agreement,
representation or undertaking made to the licensee of the Software by the
Reseller or its officers, employees or agents not contained in the License
Agreement or specifically authorized in writing by IQSC. IQSC will give the
Reseller prompt written notice of any such claim or loss.

such may be modified from time to time,



                                       2


<PAGE>   3
as long as IQSC generally provides support for such Software to others. IQSC
will enter into support and maintenance agreements directly with such licensee
upon such terms and conditions as mutually agreed upon by IQSC and the
licensee. The Reseller is not authorized to market IQSC's maintenance and
support services, but may advise a potential licensee of the availability of
such services.

     (b)  IQSC shall use reasonable efforts to make prompt delivery of the
Software sold pursuant to an Accepted Orders placed by the Reseller, but IQSC

replacement shall meet substantially the same specifications of the Software as
provided in the documents.

may be terminated by IQSC or Reseller, prior to the expiration of the term of
the appointment set forth in paragraph 6, upon a material default by the other
party which is not corrected within thirty (30) days of receipt of notice of
such termination. A material default shall include, but shall not be limited
to, the unauthorized disclosure of Information of the other party, the
unauthorized copying of the Software or Documents by Reseller or Reseller
providing copies of the Software to others in violation of the terms of this
Agreement.

14.    TRADEMARKS.

       Reseller acknowledges that the trademarks and trade names heretofore and
hereafter used by IQSC in connection with the Software (collectively

Trademarks only in accordance with guidelines provided by IQSC 



                                       6
<PAGE>   7
to Reseller from time to time during the term of this Agreement; provided that
Reseller shall not use the Trademarks in any manner likely to confuse, mislead
or deceive the public or be injurious or inimical to the best interests of
IQSC. IQSC, for any reason, may at any time upon written notice to Reseller
terminate any right granted to Reseller to use any Trademark.

14.  ASSIGNMENT.

     Neither this Agreement, or any rights hereunder, may be assigned by
Reseller and any attempt to assign this Agreement or any rights hereunder
without prior written approval by IQSC shall automatically terminate this
Agreement. The parties agree that this Agreement is in the nature of a personal
service agreement and its continuation is conditional upon Reseller being owned
in the same manner as owned on the date of this Agreement. IQSC may terminate
this Agreement upon ten (10) days prior written notice if a change in control
of Reseller has occurred without the prior written approval of IQSC. Reseller
shall promptly notify IQSC of all changes in the ownership of Reseller. IQSC
may assign and transfer this Agreement or its rights hereunder to any
affiliated IQSC and to the successor of its business. Subject to the above, this
Agreement shall be binding upon and inure to the benefit of the successors and
assigns of any party hereto.

16.  WAIVERS.

     No waiver of any provision of this Agreement shall be effective unless in
writing and executed by the party waving the right. Failure to promptly demand
compliance or performance shall not constitute a waiver of a party's right
hereunder.

17.  MISCELLANEOUS.

     (a)  Reseller shall make no representations regarding any Software or
IQSC to any potential customer or licensee and acknowledges that Reseller has
no authority to do so.

     (b)  In no event shall either party be liable to the other party for any
indirect, incidental, special, punitive or consequential damages, including but
not limited to, loss of profits or revenue, however incurred, even if such
party has been advised of the possibility of such damages.

     (c)  This Agreement sets forth the entire agreement and understanding of
the parties with respect to the subject matters hereof. The parties acknowledge
that there are no warranties or representations, including regarding the
Software, not specifically set forth herein.

     (d)  Each party represents to the other that this Agreement constitutes a
valid and binding obligation of such party and is enforceable against such
party in accordance with its terms. If any provision of this Agreement shall be
held by a court to be illegal, invalid or unenforceable, the remaining
provisions shall remain in full force and effect. Without waiving a party's
claim or breach of representation, if any provision of this Agreement in any
way contravenes any law, the parties hereto agree to revise such provisions in
such a manner as to meet the requirements of law and as nearly as possible to
reflect the original intention of the parties.

                                       7
<PAGE>   8

     (e)  This Agreement shall be construed and governed by the laws of the
State of Georgia (without giving effect to the principles of conflict of laws).

18.  ACCOUNT REGISTRATION

     Prior to beginning a sales effort into any prospect or customer account,
Reseller agrees to "register" sales opportunity with IQSC. The purpose of this
registration is to confirm that the specific opportunity with the specific
department or division of the prospect or customer is not currently on IQSC's
active prospect list. The registration request must include the company name,
address, primary contact, department or division and a brief description of the
sales opportunity. Within forty-eight (48) hours of the receipt of account
registration request, Reseller will be notified of the acceptance or rejection
of the account request. If the specific opportunity with the specific
department or division is currently on IQSC's active prospect list then
Reseller's registration request will be denied and IQSC shall have no
obligations to the Reseller (including payment  of compensation) under the
terms of this agreement. If the specific opportunity with the specific
department or division is not on IQSC's active prospect list, then it will be
registered to Reseller for a period of six (6) months. If Reseller does not
sell IQSC Software products into the registered opportunity within the six (6)
month period, the opportunity is subject to be reassigned.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the day
and year first above written.
