                               PROSPECTUS SUMMARY
 
  The following summary should be read in conjunction with, and is qualified in
its entirety by, the more detailed information, including "Risk Factors" and
the Consolidated Financial Statements and Notes thereto, appearing elsewhere in
this Prospectus. As used in this Prospectus, the terms "Inference" and the
"Company" include Inference Corporation and its subsidiaries, unless the
context otherwise indicates. The discussion in this Prospectus contains
forward-looking statements which include risks and uncertainties. The Company's
actual results could differ materially from those discussed in this Prospectus.
Factors that could cause or contribute to such differences include those
discussed in the sections entitled "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business," as
well as those discussed elsewhere in this Prospectus. Unless otherwise
indicated, the information presented in this Prospectus assumes that the
Underwriters' over-allotment option is not exercised, that all outstanding
shares of Class B Common Stock have been converted into Class A Common Stock,
and that the Company's reincorporation in Delaware has been completed.
 
                                  THE COMPANY
 
  Inference develops, markets and supports client/server software for knowledge
publishing, knowledge distribution, and content management for the front
office, where organizations interact with their external and internal
customers, prospects and vendors. Inference's CBR Express family of products
("CBR Products") facilitates successful dialogue with the customer to quickly
identify and resolve problems in external and internal customer support, sales
automation and telemarketing operations.
 
  The Company's primary focus to date has been on the customer support market,
which includes external customer support and internal help desks. The Company
believes that the customer support market is experiencing rapid growth due to
increasing customer demands, cost pressures, the proliferation of computer
users and the complexity of business applications. The customer support market
is divided into two segments: problem management, where customer calls and
information are tracked; and problem identification and resolution, where
information is obtained from the customer and used to define the problem and
provide a solution. The Company believes its strengths are in content
management and retrieval for problem identification and resolution, which
enables organizations to diagnose and solve customer problems. These
organizations are also extending the use of the Company's CBR Products in self-
service technical support applications, where knowledge is accessed directly by
customers and employees to help them resolve problems independently. For
example, the Company's product for the World Wide Web, CasePoint WebServer, is
designed to provide this self-service technical support over the Internet
allowing an increased level of customer service.
 
  The Company recently announced CBR3 Content Navigator ("CBR3"), the next
generation of CBR Products, which includes new features designed to reduce the
cost of knowledge acquisition and maintenance. CBR3 is a comprehensive content
management and retrieval system that is designed to provide a common index and
retrieval method for the wide variety of unstructured information in help desk,
customer service, human resource, and telesales and telemarketing
organizations. CBR3 products began beta testing in May 1996.
 
  The Company's CBR Products are scalable and available on popular computing
platforms, including Microsoft Windows, IBM OS/2, HP-UX and Sun Solaris. The
CBR Products support many database management systems, including Oracle,
Informix, Sybase, Microsoft's SQL Server and IBM's DB2/2. The Company's CBR
Products support stand alone, client/server, Internet and intranet
environments, providing companies with many options to deploy knowledge. The
Company also provides consulting services, technical support and training for
its CBR Products.
 
  The Company distributes its products through a direct sales force and through
indirect sales channels, including value added resellers (VARs), systems
integrators and original equipment manufacturers (OEMs). The Company has an
established international presence with significant operations in Europe and
has worldwide distribution capabilities. The Company recently established an
OEM Partner Program that now includes nine leading customer support vendors.
 
  The Company has granted licenses for its products to approximately 500
customers for use by more than 500,000 end users. The Company's customers
include IBM Corporation, Peoplesoft Inc., Halifax Building Society, AT&T Corp.,
Freightliner Corporation, Southern Electric plc and FTD Inc. The Company was
incorporated in California in 1979 and was reincorporated in Delaware in July
1996. The Company maintains its principal executive offices at 100 Rowland Way,
Novato, California 94945, and its telephone number at that location is (415)
893-7200.

          CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION
 
  Certain statements contained under "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and under "Business," as well
as other statements contained in this Prospectus regarding matters that are
not historical facts are forward-looking statements (as such term is defined
in the rules promulgated pursuant to the Securities Act of 1933, as amended
(the "Securities Act")). Because such forward-looking statements include risks
and uncertainties, actual results may differ materially from those expressed
in or implied by such forward-looking statements. Factors that could cause
actual results to differ materially include, but are not limited to, those
discussed herein under "Risk Factors." The Company undertakes no obligation to
release publicly the result of any revisions to these forward-looking
statements that may be made to reflect events or circumstances after the date
hereof or to reflect the occurrence of unanticipated events.
 
                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following
factors should be carefully considered in evaluating the Company and its
business before purchasing shares of the Class A Common Stock offered hereby.
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
  The Company has experienced significant quarterly fluctuations in operating
results and anticipates such fluctuations in the future. Typically, revenues,
operating income and net income for the Company's fourth quarter are higher
than those for the first quarter of the following year. In addition, the
Company has historically recognized a substantial portion of its license
revenues in the last month of the quarter, typically in the last week. The
Company generally ships orders as they are received and as a result has little
or no backlog. Quarterly revenues and operating results therefore depend on
the volume and timing of orders received during the quarter, which are
difficult to forecast. In addition, consulting service revenues tend to
fluctuate as projects, which may continue over several quarters, are
undertaken or completed. Operating results may also fluctuate due to factors
such as the demand for the Company's products; the size and timing of customer
orders; the introduction of new products and product enhancements by the
Company or its competitors; the budgeting cycles of customers; changes in the
proportion of revenues attributable to licenses and service fees; changes in
the level of operating expenses; and competitive conditions in the industry.
The value of individual licenses as a percentage of quarterly revenues can be
substantial, and particular licenses may generate a substantial portion of the
operating profits for the quarter in which they are signed. The sales cycle
typically ranges from three to nine months, and license signing may be delayed
for a number of reasons outside of the control of the Company. Because the
Company's staffing and other operating expenses are based on anticipated
revenues, a substantial portion of which is not typically generated until the
end of each quarter, delays in the receipt of orders can cause significant
variations in operating results from quarter to quarter. The Company also may
choose to reduce prices or to increase spending in response to competition or
to pursue new market opportunities, which may adversely affect the Company's
operating results. Accordingly, the Company believes that period-to-period
comparisons of its results of operations may not be meaningful and should not
be relied upon as an indication of future performance. Furthermore, there can
be no assurance that the Company will remain profitable. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
  Due to all of the foregoing factors, it is likely that in some future
quarters the Company's operating results will be below the expectations of
public market analysts and investors. Regardless of the general outlook for
the Company's business, the announcement of quarterly operating results below
analyst and investor expectations is likely to result in a decline in the
trading price of the Company's Class A Common Stock.

RAPID TECHNOLOGICAL CHANGE; PRODUCT TRANSITIONS
 
  The market for the Company's products is characterized by rapid
technological developments, evolving industry standards, swift changes in
customer requirements and frequent new product introductions and enhancements.
As a result, the Company's success depends upon its ability to continue to
enhance its existing
products, develop and introduce in a timely manner new products incorporating
technological advances and respond to customer requirements. To the extent one
or more of the Company's competitors introduce products that more fully
address customer requirements, the Company's business could be adversely
affected. There can be no assurance that the Company will be successful in
developing and marketing enhancements to its existing products or new products
on a timely basis or that any new or enhanced products will adequately address
the changing needs of the marketplace. If the Company is unable to develop and
introduce new products or enhancements to existing products in a timely manner
in response to changing market conditions or customer requirements, the
Company's business, operating results and financial condition will be
materially and adversely affected.
 
  Although the Company has a number of ongoing development projects, its
primary product development effort is focused on CBR3 which was released in
beta form in May 1996. CBR3 will add functionality to the current product
line, CBR Express Release 2 ("CBR2"). However, there can be no assurance that
the development of CBR3 will be completed successfully or on a timely basis or
that the product will operate successfully in commercial use or that the added
functions will meet customer requirements or that the product will achieve
market acceptance. The Company's future operations will be substantially
dependent on CBR3, and failure to achieve market acceptance of this family of
products would have a material adverse effect on the Company's business,
operating results and financial condition. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
  The Company has in the past experienced delays in software development, and
there can be no assurance that the Company will not experience further delays
in connection with its current product development or future development
activities. From time to time, the Company or its competitors may announce new
products, capabilities or technologies that have the potential to replace or
shorten the life cycles of the Company's existing products. There can be no
assurance that announcements of currently planned or other new products will
not cause customers to delay their purchasing decisions in anticipation of
such products, which could have a material adverse effect on the Company's
business, operating results and financial condition. Software products as
complex as those offered by the Company may contain undetected errors when
first introduced or as new versions are released. There can be no assurance
that errors will not be found in the Company's new or enhanced products after
commencement of commercial shipments or that modifications to such products
will not be required to satisfy customer requirements, resulting in loss of or
delay in market acceptance. Delays or difficulties associated with new product
introductions or product enhancements could have a material adverse effect on
the Company's business, operating results and financial condition. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Product Development."
 
COMPETITION
 
  The market for customer support software is highly competitive, and there
are certain competitors with substantially greater sales, marketing,
development and financial resources than the Company. Among the Company's
major competitors are Answer Systems, Inc., Astea International Inc., Clarify,
Inc. and Software Artistry, Inc. Furthermore, many potential customers develop
internal solutions by creating business applications that eliminate the need
to acquire software and services from third-party vendors such as the Company.
 
                                       6
<PAGE>
 
  The Company believes that the competitive factors affecting the market for
the Company's products and services include vendor and product reputation;
product quality, performance and price; product functionality and features;
product scalability; product integration with other enterprise applications;
the availability of products on multiple platforms; product ease-of-use; and
the quality of customer support services, documentation and training. The
relative importance of each of these factors depends upon the specific
customer involved. There can be no assurance that the Company will be able to
compete effectively with respect to any of these factors.
 
  The Company's present or future competitors may be able to develop products
comparable or superior to those offered by the Company or adapt more quickly
than the Company to new technologies or evolving customer requirements. In
order to be successful in the future, the Company must respond to
technological change, customer requirements and competitors' current products
and innovations. In particular, while the Company is currently developing
additional product enhancements that the Company believes address customer
requirements, there can be no assurance that the Company will successfully
complete the development or introduction of these additional product
enhancements on a timely basis or that these product enhancements will achieve
market acceptance. Accordingly, there can be no assurance that the Company
will be able to continue to compete effectively in its market, that
competition will not intensify or that future competition will not have a
material adverse effect on the Company's business, operating results and
financial condition.
 
MANAGEMENT OF GROWTH; DEPENDENCE UPON KEY PERSONNEL
 
  In recent years, the Company has experienced changes in its operations which
have placed significant demands on the Company's administrative, operational
and financial resources. The Company's future performance depends in
significant part upon the continued service of its key technical, sales and
senior management personnel. The loss of the services of one or more of these
key employees could have a material adverse effect on the Company's business,
operating results and financial condition. The Company's future success also
depends on its ability to attract and retain highly qualified technical, sales
and managerial personnel. Competition for such personnel is intense, and there
can be no assurance that the Company can retain its key employees or that it
can attract, assimilate or retain other highly qualified personnel in the
future. See "Management."
 
PRODUCT CONCENTRATION
 
  The Company currently derives substantially all of its revenues from
licenses of CBR Products and associated services. Broad market acceptance of
CBR Products is critical to the Company's future success. As a result, a
decline in demand for or failure to achieve broad market acceptance of CBR
Products as a result of competition, technological change or otherwise would
have a material adverse effect on the business, operating results and
financial condition of the Company. A decline in sales of CBR Products also
could have a material adverse effect on sales of other Company products and
services. In addition, the Company's future financial performance will depend
in part on the successful development, introduction and customer acceptance of
CBR3 and future versions of CBR Products. There can be no assurance that CBR3
or any future products will achieve market acceptance. See "Business--Products
and Services."

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
  International revenues accounted for 46% of total revenues in fiscal 1996.
International operations are subject to certain inherent risks including
unexpected changes in regulatory requirements; tariffs and other trade
barriers; costs and risks of localizing products for foreign countries; longer
accounts receivable payment cycles; potentially adverse tax consequences;
limits on repatriation of earnings; exchange rate fluctuations; and the
burdens of complying with a wide variety of foreign laws. There can be no
assurance that such factors will not have an adverse effect on the revenues
and earnings from the Company's future international operations and,
consequently, the Company's business, operating results and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  The trading price of the Company's Class A Common Stock could be subject to
wide fluctuations in response to quarterly variations in operating results,
announcements of technological innovations or new products by the Company or
its competitors, changes in financial estimates or recommendations by
securities analysts and other events or factors. In addition, the stock market
has experienced volatility that has particularly affected the market prices of
equity securities of many technology companies and that often has been
unrelated to the operating performance of such companies. These broad market
fluctuations may adversely affect the trading price of the Company's Class A
Common Stock.
 
UNCERTAINTY OF PROPRIETARY RIGHTS
 
  The Company's success depends in part upon its proprietary technology.
Although case-based reasoning technology is available in the public domain,
the Company believes its implementation of the CBR technology is proprietary.
The Company relies on a combination of copyright, trademark and trade secret
laws, confidentiality procedures and licensing arrangements to establish and
protect its proprietary rights. The Company does not hold any patents nor has
it obtained invention assignments from all consultants performing services for
it. Despite the precautions the Company has taken, it may be possible for an
unauthorized third party to copy or otherwise obtain and use the Company's
products, technology or other information that the Company regards as
proprietary or to develop similar products or technology independently. In
addition, effective trademark, copyright and trade secret protection may be
unavailable or limited in certain foreign countries where the Company
operates.
 
  The Company is not aware that any of its products infringe upon the
proprietary rights of third parties. There can be no assurance, however, that
third parties will not claim such infringement by the Company with respect to
current or future products. The Company expects that it will increasingly be
subject to such claims as the number of products and competitors in the
customer support software market grows and the functionality of such products
overlaps with other industry segments. Any such claims, whether or not they
are meritorious, could result in costly litigation or require the Company to
enter into royalty or licensing agreements. Such royalty or license
agreements, if required, may not be available on terms acceptable to the
Company or at all. If the Company were found to have infringed upon the
proprietary rights of third parties, it could be required to pay damages,
cease sales of the infringing products and redesign or discontinue such
products, any of which could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--
Intellectual Property and Other Proprietary Rights."

SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of the Company's Class A Common Stock in the public market after this
offering could adversely affect the market price of the Company's Class A
Common Stock. Upon completion of this offering, the Company will have
8,715,390 outstanding shares of Class A Common Stock (8,895,390 if the
underwriters over-allotment option is exercised in full), based on the number
of shares outstanding at May 31, 1996. Such shares not offered hereby will be
available for resale in the public market without restriction except for
shares held by officers and directors who must resell in accordance with Rule
144 promulgated under the Securities Act.
 
  In addition, as of May 31, 1996, (i) options to purchase a total of
1,327,570 shares of Class A Common Stock pursuant to the Company's stock
option plans and several stock option agreements were outstanding with a
weighted average exercise price of $10.25 per share, of which options to
purchase 439,263 shares of Class A Common Stock were exercisable as of May 31,
1996, (ii) performance-based options to purchase a total of 88,150 shares of
Class A Common Stock that terminate if specified performance goals are not
achieved (the exercise price of the options will be the greater of $23.00 per
share or the fair market value of the Class A Common Stock at the time of
achievement of the performance goals), and (iii) warrants to purchase 177,397
shares of Class A or Class B Common Stock were outstanding at a weighted
average exercise price of $4.98 per share. See Notes 7 and 8 of Notes to
Consolidated Financial Statements."
 
  All of the Company's officers and directors and the Selling Stockholders
have agreed that they will not, without prior written consent of Montgomery
Securities, sell, offer, contract to sell, or otherwise dispose of, any shares
of Class A Common Stock or any other securities convertible into or
exercisable or exchangeable for Class A Common Stock for a period of 90 days
after the date of this Prospectus. See "Underwriting" and "Principal and
Selling Stockholders."
 
CERTAIN PROVISIONS RELATING TO CHANGES IN CONTROL
 
  The Company's Certificate of Incorporation and Bylaws contain provisions
which may have the effect of delaying or preventing a change in control of the
Company. Such provisions include (i) a classified Board of Directors, (ii) a
limitation on stockholder action by written consent, and (iii) advance notice
procedures for stockholder proposals and nominations. In addition, the
Certificate of Incorporation permits the Company's Board of Directors to issue
up to 2,000,000 shares of Preferred Stock and to determine the price, rights,
preferences and privileges of those shares without any further vote or action
by the stockholders. The rights of the holders of Common Stock will be subject
to, and may be adversely affected by, the rights of the holders of any
Preferred Stock that may be issued in the future. The issuance of Preferred
Stock could have the effect of making it more difficult for a third party to
acquire a majority of the outstanding voting stock of the Company. The Company
has no present plans to issue shares of Preferred Stock.

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 629,754 shares of Class
A Common Stock offered by the Company hereby are estimated to be $13,235,000
($17,233,000 if the Underwriters' over-allotment option is exercised in full)
at an assumed public offering price of $23.50 per share and after deducting
underwriting discounts and commissions and estimated offering expenses. The
Company will not receive any proceeds from the sale of shares being sold by
the Selling Stockholders. The Company will use the net proceeds for general
corporate purposes, including working capital and the possible acquisition of
businesses, products and technologies that are complementary to those of the
Company. The Company has no present plans, agreements or commitments and is
not currently engaged in any negotiations with respect to any such
acquisition. Pending such uses, the net proceeds of this offering will be
invested in U.S. government securities and other short-term investment grade,
interest-bearing securities.
 
                      PRICE RANGE OF CLASS A COMMON STOCK
 
  The Company effected its initial public offering on June 29, 1995 at a price
to the public of $11.00 per share. The Company's Class A Common Stock is
traded on the Nasdaq National Market under the symbol "INFR." The following
table sets forth for the quarterly periods indicated the range of high and low
closing sales prices for the Company's Class A Common Stock:

                                DIVIDEND POLICY

stock except for a dividend of $114,000 paid by the Company in May 1995 (prior
to the Company's initial public offering) to the holders of one class of the
Company's Preferred Stock pursuant to the terms of the Company's then-
effective Restated Articles of Incorporation. The Company does not expect to
declare or pay any further cash dividends in the foreseeable future.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  The Company was founded in 1979 to provide consulting services. In 1985, the
Company made its first commercial shipment of a software application
development tool ("ART"). From 1985 until May 1991, revenues of the Company
were primarily derived from the sale of ART products and related consulting
services. In May 1991, the Company commercially shipped its first CBR Product.
 
  From May 1991 through April 30, 1995, the Company's revenues were derived
from two separate product lines: (i) the customer support product line,
consisting of CBR Products and associated services (the "CBR Business"); and
(ii) the application development and solutions product line, which included
the Company's products: ART, ART-IM and ART*Enterprise ("Tools") and
associated services (the "Tools Business"). In the fourth quarter of fiscal
1995, the Company made a strategic decision to focus on the CBR Business and
to divest the Tools Business. Effective May 1, 1995, the Company transferred
certain assets and liabilities of the Tools Business to a wholly-owned
subsidiary ("Brightware") of the Company and distributed all of the shares of
such subsidiary to the Company's stockholders (the "Spin-Off"). As part of the
Spin-Off, the Company entered into an agreement with Brightware to provide
certain services to the new entity including operational and systems support,
facilities and administrative support and certain technical and customer
support. This agreement expired on January 31, 1996. The amount received for
these services was $760,000.
 
  The Company's revenues are derived principally from two sources: (i) fees
for licenses of the Company's software products and technology and (ii) fees
for consulting services, maintenance (technical support and upgrades of
software products) and training. Revenues from software licenses are generally
recognized upon shipment, unless the Company has significant future
obligations to the customer, in which case revenues are recognized when such
obligations are satisfied. Revenues from consulting and training are
recognized as the related services are performed, and maintenance revenues are
deferred and recognized over the term of the Company's maintenance contracts,
typically one year.
 
  Although the Company has experienced significant growth in revenues from its
CBR Products, the Company does not believe prior growth rates are indicative
of the Company's future operating results. In addition, the Company expects
increased competition and intends to invest significantly in its business. As
a result, there can be no assurance that the Company will remain profitable on
a quarterly or annual basis. The Company's future operating results are
difficult to predict and may fluctuate due to factors such as the demand for
the Company's products; the size and timing of customer orders; the
introduction of new products and product enhancements by the Company or its
competitors; the budgeting cycles of customers; changes in the proportion of
revenues attributable to licenses and service fees; changes in the level of
operating expenses; and competitive conditions in the industry.
 
  The Company believes that its products are competitively priced with other
products in the customer support market. However, the market for the Company's
products is highly competitive, and the Company expects that it will face
increasing pricing pressures from its current competitors and new market
entrants. Any material reduction in the price of the Company's products would
negatively affect gross margins and could materially adversely affect the
Company's business, operating results and financial condition if the Company
were unable to increase unit sales.
 
  The Company intends to hire a significant number of additional sales
personnel. Competition for such personnel is intense, and there can be no
assurance that the Company can retain its existing sales personnel or that it
can attract, assimilate or retain additional highly qualified sales personnel
in the future. If the Company is unable to hire such personnel on a timely
basis, the Company's business, operating results and financial condition could
be adversely affected.

THREE MONTHS ENDED APRIL 30, 1995 AND APRIL 30, 1996
 
 Revenues
 
  Product revenues increased from $2,953,000 in the three months ended April
30, 1995 to $4,978,000 in the three months ended April 30, 1996, representing
a 69% increase. The Company believes this increase is a result of the market
acceptance of CBR Products. Substantially all of the growth in revenues from
CBR Products is due to higher unit sales volumes; the prices of the Company's
CBR Products have remained relatively constant. Product revenues represented
53% and 55% of total revenues for the three months ended April 30, 1995 and
April 30, 1996, respectively. International product revenues increased from
$709,000 in the three months ended April 30, 1995 to $1,713,000 in the three
months ended April 30, 1996, representing a 142% increase.
 
  Total service revenues increased from $2,671,000 in the three months ended
April 30, 1995 to $4,149,000 in the three months ended April 30, 1996,
representing a 55% increase. This increase is primarily the result of
consulting projects which were initiated in connection with the closing of
increased CBR Product transactions, as discussed above. During the three
months ended April 30, 1995 and April 30, 1996, two customers, in the
aggregate, accounted for 15% and 25% of service revenues, respectively. The
loss of, or reduced demand for consulting services from these two customers or
any of the Company's other major services customers could have an adverse
effect on the Company's results of operations. International service revenues
decreased from $1,693,000 in the three months ended April 30, 1995 to
$1,593,000 in the three months ended April 30, 1996 and represented 63% and
38% of total service revenues, respectively.
 
  Total international revenues increased from $2,402,000 in the three months
ended April 30, 1995 to $3,306,000 in the three months ended April 30, 1996,
representing a 38% increase. Total international revenues for the three months
ended April 30, 1995 and April 30, 1996 represented 43% and 36% of total
revenues, respectively. The Company currently has subsidiaries in the United
Kingdom, Germany, France and the Netherlands, offering licenses and consulting
services, and manages 22 distributors worldwide, serving Europe, the Middle
East and Africa, and Asia and the Pacific Rim. International revenues,
however, are subject to various risks, including unexpected changes in
regulatory requirements, tariffs and other trade barriers; costs and risks of
localizing products for foreign countries; longer accounts receivable payment
cycles; potentially adverse tax consequences; repatriation of earnings;
exchange rate fluctuations; and the burdens of complying with a wide variety
of foreign laws. There can be no assurance that such factors will not have an
adverse effect on the revenues from the Company's future international sales
and, consequently, the Company's results of operations.
 
 Cost of Product Revenues
 
  Cost of product revenues, consisting primarily of the costs of product media
and duplication, manuals, packaging materials, personnel-related costs,
shipping expenses and royalties paid to third-party vendors, increased from
$239,000 in the three months ended April 30, 1995 to $346,000 in the three
months ended April 30, 1996, representing a 45% increase. The gross margin on
product revenues was 92% and 93% for the three months ended April 30, 1995 and
April 30, 1996, respectively.
 
 Cost of Service Revenues
 
  Cost of service revenues, consisting principally of personnel-related costs
for consulting, training and technical support, increased from $1,888,000 in
the three months ended April 30, 1995 to $2,474,000 in the three months ended
April 30, 1996, representing a 31% increase. The gross margin on service
revenues was 29% and 40% for the three months ended April 30, 1995 and April
30, 1996, respectively. The increase in gross margin on service revenues was
primarily the result of the increased utilization of consulting services'
employees and the increased renewal rate of maintenance for CBR Products. Cost
of service revenues typically varies depending on the revenue mix of training,
consulting services and technical support. Due to the Company's reliance on
lower margin service revenues, the Company's overall operating margins may be
lower than those for software companies that do not derive a significant
percentage of their revenues from services. The Company anticipates hiring
additional employees to handle the consulting and support demand, which could
result in decreased gross margins on service revenues.

 Product Development
 
  Product development expense consists primarily of employee-related costs,
including salaries, benefits, equipment and facility costs, incurred in the
research, design, development and enhancement of CBR Products. Product
development expenditures, including amounts capitalized, increased from
$465,000 in the three months ended April 30, 1995 to $711,000 in the three
months ended April 30, 1996, representing a 53% increase. This increase is the
result of the Company's strategy to invest in enhancing and further developing
CBR Products. Product development expense as a percentage of revenues was 7%
and 8% for the three months ended April 30, 1995 and April 30, 1996,
respectively. Capitalized software development costs were $50,000 and $0 for
the quarters ended April 30, 1995 and April 30, 1996, respectively.
 
 Sales and Marketing
 
  Sales and marketing expense consists primarily of salaries, benefits and
commissions of sales and marketing personnel, trade shows and promotional
expenses, and non-chargeable customer service and sales support. Sales and
marketing expense increased from $2,444,000 in the three months ended April
30, 1995 to $4,230,000 in the three months ended April 30, 1996, representing
a 73% increase. This increase is primarily the result of the expansion of the
Company's direct sales force and the marketing efforts that commenced in
fiscal 1996 and are continuing into fiscal 1997. Sales and marketing expense
as a percentage of revenues was 44% and 47% for the three months ended April
30, 1995 and April 30, 1996, respectively.
 
 General and Administrative
 
  General and administrative expense consists of the personnel costs for
finance and accounting, human resources, information systems and general
management of the Company. General and administrative expense increased from
$280,000 in the three months ended April 30, 1995 to $665,000 in the three
months ended April 30, 1996, representing a 138% increase. This increase is
primarily attributable to increased staffing and associated expenses necessary
to manage and support the Company's growth, both domestically and
internationally, and the costs of being a public company. General and
administrative expense as a percentage of revenues was 5% and 7% for the three
months ended April 30, 1995 and April 30, 1996, respectively. The Company
believes that its general and administrative expense will continue to increase
in dollar amounts in the future due to the Company's expansion of its staffing
to handle increased infrastructure requirements.
 
 Non-Employee Stock Option Related Expenses
 
  During the three months ended April 30, 1996, the Company incurred payroll-
related taxes as a result of the exercise of non-qualified stock options held
by former Inference employees. This one-time charge amounted to $215,000 and
has been accounted for separate from operating income. In connection with
these option exercises, the Company will be able to take a tax deduction, if
and when adequate taxable income is earned, of approximately $7,500,000 for
compensation expense; this tax benefit, however, will be accounted for when
utilized as an adjustment to stockholders' equity.
 
 Net Interest Income and Income Taxes
 
  Net interest income increased from $6,000 in the three months ended April
30, 1995 to $292,000 in the three months ended April 30, 1996. This increase
is attributable to the interest earned on the proceeds of the Company's
initial public offering which closed in July 1995. The Company's provision for
taxes in the three months ended April 30, 1996 represented the accrual of
foreign taxes and federal alternative minimum taxes. Federal and state taxes
have not been significant as a result of available federal and state net
operating loss carryforwards.

YEARS ENDED JANUARY 31, 1994, JANUARY 31, 1995 AND JANUARY 31, 1996
 
 Revenues
 
  Total revenues increased from $27,327,000 in fiscal 1994 to $28,499,000 in
fiscal 1995, representing an increase of 4%, and increased to $29,395,000 in
fiscal 1996, representing an increase of 3% over fiscal 1995. The increased
revenues in fiscal 1995 and fiscal 1996 resulted from increases in product
revenues offset by a decrease in service revenues.
 
  International revenues amounted to $6,209,000, $10,419,000, and $13,550,000
for fiscal 1994, 1995, and 1996, respectively, representing 23%, 37%, and 46%
of total revenues for such periods, respectively. The increase in
international revenues from fiscal 1994 to fiscal 1995 was the result of a
significant increase in service revenue. The increase in international
revenues from fiscal 1995 to fiscal 1996 was attributable to increases in both
service and product revenues.
 
 Product Revenues
 
  Product revenues increased from $10,243,000 in fiscal 1994 to $12,020,000 in
fiscal 1995, representing an increase of 17%, and increased to $16,878,000 in
fiscal 1996, representing an increase of 40% over fiscal 1995. Product
revenues represented 37%, 42%, and 57% of total revenues for fiscal years
1994, 1995, and 1996, respectively. Product revenues have principally been
derived from direct licenses of the Company's software products to end users.
Although the Company believes that such direct licenses will continue to
account for a major portion of product revenues, the Company expects that
licenses of software through original equipment manufacturers (OEMs), value
added resellers (VARs) and other indirect channels will increase as a
percentage of product revenues.
 
  CBR product revenues increased from $6,662,000 in fiscal 1994 to $9,790,000
in fiscal 1995, representing an increase of 47%, and increased to $16,479,000
in fiscal 1996, representing an increase of 68% over fiscal 1995. The Company
believes this increase was a result of the growing market acceptance of the
CBR Products. Substantially all of the growth in CBR product revenues was due
to higher unit sales volumes; the prices of the Company's CBR Products have
remained relatively constant. Included in the fiscal 1996 increase in revenues
from CBR Products was license agreements with four customers that together
amounted to 19% of total product revenues for the year ended January 31, 1996.
 
  Tools products, which consist of the Company's application development
tools: ART, ART-IM and ART*Enterprise, experienced a decline in revenues in
recent years, contributing to the Company's decision to focus on CBR Products.
Tools product revenues decreased from $3,581,000 in fiscal 1994 to $2,230,000
in fiscal 1995, representing a decrease of 38%, and further decreased to
$399,000 in fiscal 1996, representing a decrease of 82% from fiscal 1995.
 
  International product revenues represented 29%, 33%, and 40% of total
product revenues for fiscal years 1994, 1995, and 1996, respectively.
 
 Service Revenues
 
  Service revenues decreased from $17,084,000 in fiscal 1994 to $16,479,000 in
fiscal 1995, representing a decrease of 4%, and decreased to $12,517,000 in
fiscal 1996, representing a decrease of 24% from fiscal 1995. Service revenues
represented 63%, 58%, and 43% of total revenues for fiscal 1994, 1995, and
1996, respectively.
 
  North American service revenues decreased 28% from $13,827,000 in fiscal
1994 to $10,017,000 in fiscal 1995, and decreased to $5,726,000 in fiscal
1996, representing a decrease of 43% from fiscal 1995. The primary cause of
the decrease in North American service revenues between fiscal 1994 and fiscal
1995 was a single customer contract associated with the Tools Business. The
contract was commenced in fiscal 1993 and ended in fiscal 1994. This customer
represented 21% of North American service revenues for fiscal 1994. The
decrease in service revenues between fiscal 1996 and fiscal 1995 was the
result of the spin-off of the Tools Business which was more services oriented.
 
                                      16
<PAGE>
 
  International service revenues increased from $3,257,000 in fiscal 1994 to
$6,462,000 in fiscal 1995, representing an increase of 98%, and increased to
$6,791,000 in fiscal 1996, representing an increase of 5% from fiscal 1995.
International service revenues represented 19%, 39%, and 54% of total service
revenues for fiscal 1994, 1995 and 1996, respectively. The increase in
international service revenues was a result of increased consulting services.
During fiscal 1994, 1995, and 1996, one customer accounted for 52%, 28%, and
25% of international service revenues, respectively. This customer had a
representative on the Company's Board of Directors through April 1995.
 
 Cost of Product Revenues
 
  Cost of product revenues increased 2% from $1,575,000 in fiscal 1994 to
$1,611,000 in fiscal 1995 and increased to $1,710,000 in fiscal 1996,
representing an increase of 6% from fiscal 1995. The gross margin on product
revenues was 85%, 87%, and 90% in fiscal 1994, 1995, and 1996, respectively.
 
 Cost of Service Revenues
 
  Cost of service revenues decreased 6% from $13,111,000 in fiscal 1994 to
$12,292,000 in fiscal 1995, and decreased to $7,667,000 in fiscal 1996,
representing a decrease of 38% from fiscal 1995. The gross margin on service
revenues was 23%, 25%, and 39% in fiscal 1994, 1995, and 1996, respectively.
The improved gross margin in fiscal 1996 was primarily the result of the
increased utilization of consultants and the increased renewal rate of
maintenance on CBR Products.
 
 Product Development
 
  Product development expense decreased 26% from $3,731,000 in fiscal 1994 to
$2,753,000 in fiscal 1995, and decreased to $1,959,000 in fiscal 1996,
representing a 29% decrease from fiscal 1995. Product development expense as a
percentage of total revenues was 14%, 10%, and 7% for fiscal 1994, 1995, and
1996, respectively. Capitalized software development costs amounted to
$630,000, $720,000, and $50,000 in fiscal 1994, 1995, and 1996, respectively.
Product development expenditures as a percentage of total revenues, including
amounts capitalized, were approximately 16%, 12%, and 7% in fiscal 1994, 1995,
and 1996, respectively. The percentage and dollar amount decrease in product
development expense was the result of headcount reductions and a restructuring
of the product development organization as a result of the continued decline
in product revenues from the Tools Business, as well as the spin-off of the
Tools Business in May 1995.
 
  The Company believes that continued commitment to product development will
be required for the Company's CBR Products to obtain a competitive advantage.
Accordingly, the Company intends to allocate increasing resources to product
research and development, but such expenses may continue to vary as a
percentage of total revenues.
 
 Sales and Marketing
 
  Sales and marketing expense increased 10% from $8,554,000 in fiscal 1994 to
$9,414,000 in fiscal 1995, and increased to $13,066,000 in fiscal 1996,
representing a 39% increase from fiscal 1995. This increase was the result of
the expansion of the Company's direct sales force and related marketing
efforts, both in North America and internationally. Sales and marketing
expense as a percentage of total revenues was 31%, 33%, and 44% in fiscal
1994, 1995, and 1996, respectively.

 General and Administrative
 
  General and administrative expense decreased 11% from $1,587,000 in fiscal
1994 to $1,420,000 in fiscal 1995, and increased to $1,537,000 in fiscal 1996,
representing an increase of 8% over fiscal 1995. The decrease in general and
administrative expense during fiscal 1995 was the result of certain headcount
reductions and other cost control measures. The increase in general and
administrative expense in fiscal 1996 was attributable to the relocation of
the Company's corporate headquarters to Northern California, as well as
increased headcount due to the Company's increased infrastructure
requirements. General and administrative expense as a percentage of total
revenues was 6%, 5%, and 5% in fiscal 1994, 1995, and 1996, respectively.
 
 Non-Recurring
 
  During fiscal 1995, the Company invested in the development of a new
business concept unrelated to its current businesses or product groups,
managed by the Company's then Chairman of the Board of Directors. In November
1994, the Company made a strategic decision to discontinue its efforts in this
area. In connection with this decision, the Company entered into a severance
agreement with the Chairman of the Board of Directors effective February 28,
1995, which provided for the continuation of his monthly salary through April
30, 1995. Costs associated with the severance agreement, as well as other
costs incurred related to this discontinued business venture were recorded in
fiscal 1995 as a non-recurring expense. In addition, non-recurring expense
included approximately $200,000 accrued in the fourth quarter of fiscal 1995
for lease payments associated with the early termination of the Company's
European headquarters facility lease, in order to relocate to a larger
facility.
 
 Net Interest Income
 
  Net interest income increased from $84,000 in the year ended January 31,
1995 to $722,000 in the year ended January 31, 1996. This increase was
attributable to the interest earned on the proceeds of the Company's initial
public offering.
 
 Income Taxes
 
  The Company's effective tax rate of 34% in the year ended January 31, 1995
represented the accrual of foreign taxes. Federal and state taxes for fiscal
1995 were not provided as a result of the utilization of net operating loss
carryforwards. The Company's provision for taxes in the year ended January 31,
1996 represented the accrual of foreign taxes and federal alternative minimum
taxes; the resulting effective tax rate was approximately 5%.
 
  The Company's net operating loss carryforwards of approximately $17,700,000
and general business credits of $1,000,000 expire in various years through
2009. Based on the Internal Revenue Code, the future use of these
carryforwards would be subject to an annual limitation should a 50% change in
ownership of the Company's stock occur within any three-year period. However,
the Company believes that any limitations would not have a material impact on
its ability to utilize these carryforwards.

  The Company has experienced significant quarterly fluctuations in operating
results and anticipates such fluctuations in the future. The Company generally
ships orders as they are received and as a result typically has little or no
backlog. Quarterly revenues and operating results therefore depend on the
volume and timing of orders received during the quarter, which are difficult
to forecast. Historically, the Company has often recognized a substantial
portion of its license revenues in the last month of the quarter, typically in
the last week. In addition, consulting service revenues tend to fluctuate as
projects, which may continue over several quarters, are undertaken or
completed. The Company's operating results may also fluctuate due to a variety
of factors. Because the Company's staffing and other operating expenses are
based on anticipated revenue, a substantial portion of which is not typically
generated until the end of each quarter, delays in the receipt of orders can
cause significant variations in operating results from quarter to quarter. The
value of individual licenses as a percentage of quarterly revenues can be
substantial, and particular licenses may generate a substantial portion of the
operating profits for the quarter in which they are signed. All of the
Company's license fees are non-recurring. Accordingly, license fees for any
quarter are not indicative of future license fees.
 
  The Company's revenues historically have been higher in the fourth quarter
of each fiscal year than in the first quarter of the following fiscal year.
The Company believes that fourth quarter product revenues are positively
impacted by year-end capital purchases by some large corporate customers, as
well as the Company's sales compensation plans. The Company expects that this
will continue for the foreseeable future and may intensify depending upon the
timing of new product introductions by the Company.
 
  Because of these and other factors affecting the Company's operating
results, past financial performance should not be considered a reliable
indicator of future performance, and investors should not use historical
trends to anticipate results or trends in future periods. In addition, the
Company's participation in the highly dynamic computer software industry often
results in significant volatility in the Company's stock price.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash and cash equivalents at April 30, 1996 were $22,430,000, an increase of
$3,811,000 since January 31, 1996. Working capital at April 30, 1996 was
$27,946,000. In July 1995, the Company completed its initial public offering
of 2,130,000 shares of Class A Common Stock. The Company received net proceeds
of approximately $20 million after deducting expenses and underwriting
discounts and commissions.
 
  Net cash used in operating activities amounted to $701,000 during the
quarter ended April 30, 1996.
 
  Investing activities for the quarter ended April 30, 1996 included $386,000
for purchases of property and equipment, which was offset by the maturity of
short-term investments which amounted to $3,607,000. The Company currently has
no significant capital commitments for fiscal 1997.
 
  Cash provided by financing activities in the quarter ended April 30, 1996
amounted to $1,291,000 from the exercise of options and warrants to purchase
common stock.
 
  The Company's international operations are principally transacted in British
pounds and German marks. Translation into the Company's reporting currency,
the U.S. dollar, has not historically had a material impact on the Company's
financial position. Additionally, the Company's level of unhedged net assets
denominated in currencies other than the functional currency has not exposed
the Company to material risk associated with fluctuations in currency rates.
Given this and the relatively stable nature of the exchange rates between the
British pound and the German mark, and the U.S. dollar, the Company has not
considered it necessary to use foreign currency contracts or other derivative
instruments to manage changes in currency rates. However, future changes in
the exchange rates between the foreign currencies and the U.S. dollar could
have an adverse effect on the Company's financial position.
 
  The Company believes that existing cash balances, together with anticipated
cash flow from operations and the proceeds of this offering, will be
sufficient to meet its working capital and capital expenditure requirements
for at least the next twelve months.

                                   BUSINESS
 
  Inference develops, markets and supports client/server software for
knowledge publishing, knowledge distribution, and content management for the
front office, where organizations interact with their external and internal
customers, prospects and vendors. Inference's CBR Express family of products
("CBR Products") facilitates successful dialogue with the customer to quickly
identify and resolve problems in external and internal customer support, sales
automation and telemarketing operations.
 
  The Company's primary focus to date has been on the customer support market,
which includes external customer support and internal help desks. The Company
believes that the customer support market is experiencing rapid growth due to
increasing customer demands, cost pressures, the proliferation of computer
users and the complexity of business applications. The customer support market
is divided into two segments: problem management, where customer calls and
information are tracked; and problem identification and resolution, where
information is obtained from the customer and used to define the problem and
provide a solution. The Company believes its strengths are in content
management and retrieval for problem identification and resolution, which
enables organizations to diagnose and solve customer problems. These
organizations are also extending the use of the Company's CBR Products in
self-service technical support applications, where knowledge is accessed
directly by customers and employees to help them resolve problems
independently. For example, the Company's product for the World Wide Web,
CasePoint WebServer, is designed to provide this self-service technical
support over the Internet allowing an increased level of customer service.
 
  The Company recently announced CBR3 Content Navigator ("CBR3"), the next
generation of CBR Products, which includes new features designed to reduce the
cost of knowledge acquisition and maintenance. CBR3 is a comprehensive content
management and retrieval system that is designed to provide a common index and
retrieval method for the wide variety of unstructured information in help
desk, customer service, human resource, and telesales and telemarketing
organizations. CBR3 products began beta testing in May 1996.
 
  The Company's CBR Products are scalable and available on popular computing
platforms, including Microsoft Windows, IBM OS/2, HP-UX and Sun Solaris. The
CBR Products support many database management systems, including Oracle,
Informix, Sybase, Microsoft's SQL Server and IBM's DB2/2. The Company's CBR
Products support stand alone, client/server, Internet and intranet
environments, providing companies with many options to deploy knowledge. The
Company also provides consulting services, technical support and training for
its CBR Products.
 
INDUSTRY BACKGROUND
 
  Customer support has become a major focus area for companies seeking to
differentiate themselves by offering superior customer service. Customers
today have greater expectations from interactions with suppliers. In addition,
sophisticated products are increasingly being sold to broader markets of first
time buyers. At the same time, suppliers are dealing with significant rates of
employee turnover in customer service and support operations. Organizations
that recognize the lifetime value of a customer are investing to support
external customers to improve repeat sales potential.
 
  In addition to the challenges of serving external customers, companies are
facing increasing demands to support internal "customers." Throughout
companies, the transition to group-oriented network computing (client/server)
and the use of hardware and software from multiple vendors greatly increase
the complexity of systems management and support. Such complexity often
outpaces employees' abilities to use and/or manage the system, thereby
creating a new class of internal customers who require support. As a result,
organizations train or hire internal support talent to protect and leverage
their investment in these distributed, client/server systems. This additional
investment usually takes the form of an internal help desk that gives
employees the same type of support that hardware and software vendors provide
to their external customers.
 
                                      21
<PAGE>
 
  Companies have attempted to improve responsiveness to both external and
internal customers by adding personnel. In many cases, such personnel
increases have resulted in increased costs with limited improvements in
customer satisfaction. In addition, experienced personnel with the technical
knowledge required for external customer support and internal help desk
positions are in short supply.
 
  In recent years, companies have turned to software automation to assist the
customer support staff in contact with external and internal customers in
order to improve and leverage those valuable interactions. Specifically,
organizations are turning to software programs to help them recognize the
customer and identify and resolve problems, including efficient implementation
of the appropriate solution. Companies have begun to deploy call avoidance
programs that make "onboard" problem identification and resolution technology
directly available to the user through the Internet on the World Wide Web or
by embedding problem resolution tools or technologies into their products.
Initial client/server applications available to automate the customer support
and internal help desk functions focused primarily on maintaining user-
specific records and tracking reported problems. These systems, which have
improved customer support and internal help desk operations, address primarily
the problem management segment of this market. Automation of problem
management itself, however, does not reduce the required individual attention
necessary to identify and resolve problems presented to customer support
personnel.
 
  Because the identification and resolution of problems presented to support
personnel remains a time consuming and expensive process, companies are
seeking to automate the identification and resolution of support problems.
This capability, however, is not generally available in many problem
management software applications offered today. While problem identification
and resolution applications are available, the Company believes that many of
these applications are limited to customer support and do not fully address
the complexity, scalability, ease of implementation and use requirements of
most customer service and support operations.
 
THE INFERENCE SOLUTION
 
  The Company believes that its proprietary implementation of case-based
reasoning ("CBR") technology is the core technology that differentiates the
Company in the marketplace. The Company's CBR Products incorporate this
adaptable and scalable technology that is designed to support front office
operations and ultimately make problem identification and resolution
technology directly available to the user. CBR Products enable customer
support and internal help desk personnel to effectively manage customer
interactions, identify customer problems and quickly provide resolutions. Key
elements of CBR Products include an intuitive user interface, a query
refinement capability, an easy-to-use authoring environment, support for case
base objects that reference multiple information formats (such as documents,
databases and multimedia content), search matching algorithms and a fully
interactive and dynamic information maintenance capability. CBR Products, also
utilize an easy-to-use, intuitive question-and-answer technique to efficiently
match inquiries with available data. This question-and-answer approach allows
support personnel with a wide range of experience, from novice to expert, to
establish a successful dialogue with customers and to quickly identify and
resolve their problems. CBR Products provide a uniform graphical point-and-
click interface to case bases referencing structured information in computer
databases and unstructured information such as policy manuals, free text,
publications, multimedia content and business know-how. The Company believes
its basic technology has practical applicability for a wide range of business
processes, including sales automation, telemarketing, product configuration
and selection, document management and navigation, personnel evaluation, and
intelligent order entry. The Company believes that this uniform access to case
bases that reference structured and unstructured information combined with a
flexible, responsive and easy-to-use delivery system offers a competitive
advantage in the front office.

STRATEGY
 
  The Company's mission is to be the leading provider of strategic platforms
for managing and retrieving content. The following are the key elements of the
Company's strategy:
 
  Focus on Problem Identification and Resolution. The Company's primary
objective is to establish its CBR Products as the problem identification and
resolution products of choice for internal and external customer support. The
Company believes that it can establish this position due to the key attributes
of the CBR Products. The Company intends to continue its focus on problem
identification and resolution and to leverage existing products by adding
features and functionality to extend the Company's CBR product line beyond
customer support, sales automation and telemarketing operations.
 
  Provide Multiple Platform Support. CBR Products are available on several
computing platforms, including Microsoft Windows 3.x, Windows 95, Windows NT,
IBM OS/2, HP-UX and Sun Solaris for SPARC, and support many database
management systems, including Oracle, Informix, Sybase, Microsoft's SQL Server
and IBM's DB2/2. Additionally, certain of the Company's products are available
in up to 15 languages.
 
  Third-Party Integration. The open architecture of CBR Products makes it
possible to integrate it with a broad range of related technologies and
products in the computing and telephony areas. Components of the CBR Products
can be embedded in legacy applications as either call-in or call-out
functions, and they can be integrated with many popular applications, such as
electronic mail, document or media browsers, spreadsheets and document
editors. The Company's software also provides an interface to a number of
third-party call tracking and help desk automation systems.
 
  Broaden Indirect Channels of Distribution. To date, the majority of the
Company's revenues have been generated through its direct sales force and
through indirect sales channels, including VARs, systems integrators and OEMs.
The Company recently established an OEM Partner Program that now includes nine
leading customer support vendors. The Company believes that the OEM Partners
will provide more opportunities for the sale of Inference's CBR Products.
 
  Build On Established International Presence. The Company currently derives a
significant portion of its revenues from its international operations and
believes that it enjoys a leading market position in the United Kingdom and
Germany. The Company recently established operations in France and Holland and
is expanding its international distribution base in order to expand its
penetration of global markets.
 
  Leverage Product Sales by Providing Professional Consulting Services. To
address the growing demand for custom applications, the Company employs a
staff of professional consultants who are experienced in the design and
implementation of problem identification and resolution applications. These
individuals are also skilled at managing the development and deployment of
custom solutions using either customer or third-party programmers. The Company
intends to offer these consulting services as a secondary yet effective and
differentiating component of its sales strategy. These services are offered at
rates that the Company believes are competitive with, but generally not lower
than, other professional consulting firms.

PRODUCTS AND SERVICES
 
 Current Products
 
  CBR2, the Company's principal product, is a suite of client/server
applications that are designed to provide access to case bases that reference
structured and unstructured information for use in the front office. CBR2's
primary use is in external customer support and internal help desk operations.
 
 
  The diagram below depicts the basic operations of the problem identification
and resolution technology in CBR2:
 
 
  In the diagram, the problem identification and resolution process begins
with the user entering a problem using natural language ("I'm having trouble
with my printer output"). CBR2 uses this statement to create a search case.
CBR2 compares this search case to each case in the case base index and
calculates a relevancy score (90% to 60% in this example). CBR2 then sorts the
cases from high to low by the relevancy score and returns this sorted list to
the user. In addition, CBR2 responds with a set of questions which prompts the
user to ask the customer relevant questions ("What does the print quality look
like?"). The user types in the customer's response ("The paper has white
streaks"), and CBR2 expands the attributes of the search case. CBR2 repeats
the ranking and question generation process until the relevancy ranking for
the top case exceeds a preset threshold (greater than 90% similarity),
indicating that it has found the best solution. By selecting the indicated
solution, the user will activate a display of instructions to resolve the
problem, a source document for review or a multimedia annotation.

</TABLE>
 
  The CBR2 products consist of the following unbundled components described
below:
 
  CBR Express. CBR Express is a client/server application that provides a
series of templates for "authoring" (developing) case histories, business
policies and information stored in documents into a format readable by the
CasePoint viewer of CBR2.
 
    Author. CBR Express Author contains several panels, which are intuitive
  graphical user interfaces (GUIs) that require little user training and help
  the user create case descriptions, related questions and appropriate
  actions that are stored in a case base. A separate panel searches and
  validates the information.
 
    Generator. CBR Express Generator uses the Company's proprietary
  technology to automatically index Microsoft Word, HTML or ASCII documents
  in a format that can be read and utilized by the Author module. CBR Express
  Generator allows customers to combine document information with
  experiential case history and database information in a single
  client/server application.
 
    Tester. CBR Express Tester is an automated testing tool for validating
  unstructured information stored in CBR case bases and document bases. CBR
  Express Tester eliminates redundancies and unused information and also
  identifies incomplete information. CBR Express Tester can operate on a
  stand-alone basis or in a client/server environment.
 
  CasePoint. The CasePoint viewer is the primary end user search interface for
CBR information bases. It runs as a client under Microsoft Windows 95 and
Windows NT, IBM OS/2, HP-UX and Sun Solaris for SPARC and offers a GUI for
submitting queries and searching information bases. CasePoint is offered in
three versions: (i) CasePoint, (ii) CasePoint End User for deployment of
knowledge, and (iii) CasePoint for Pre-Packaged Knowledge for use only with
published case bases. It contains scalable, proprietary search algorithms and
features an interactive question-and-answer methodology that helps users
refine their queries to generate the most appropriate response. CasePoint
supports Dynamic Data Exchange ("DDE") interfaces under Microsoft Windows and
IBM OS/2 and Remote Procedure Call ("RPC") interfaces under UNIX. CasePoint
can support databases stored in Oracle, Informix, Sybase, Microsoft's SQL
Server and IBM's DB2/2.
 
  CasePoint Search Engine. CasePoint Search Engine frequently runs under third
party programs or other OEM programs. It has no user interface of its own but
instead the Developer Kit provides an extensive set of functions. CasePoint
Search Engine offers the features and functionality of CasePoint as a Dynamic
Link Library ("DLL") under Microsoft Windows and IBM OS/2 and a Shareable
Library ("SL") under UNIX.
 
                                      25
<PAGE>
 
  CasePoint WebServer. CasePoint WebServer adds the World Wide Web as a
vehicle for delivering knowledge in front office applications, using
Inference's CBR technology. CasePoint WebServer is an interactive World Wide
Web application that enables organizations to increase their level of customer
service by allowing customers to directly access troubleshooting information
and product information--without having to wait to contact a service agent.
CasePoint WebServer uses standard RPC facilities and is written to the Common
Gateway Interface ("CGI") specification and can be accessed using any World
Wide Web browser.
 
  Pre-Packaged Knowledge Bases. Unlike external customer support operations,
internal help desks often find themselves dealing with a number of common
"domains" of problem areas relating to support of client/server systems. In
addressing the growing need for higher quality, cost-effective service and
support, the Company has formed the Knowledge Publishing Division to provide
off-the-shelf content to users and help desks. Knowledge Publishing Division's
initial suite of products will be a set of CBR-optimized pre-packaged
knowledge based on content developed by KnowledgeBroker, Inc. ("KBI") and
ServiceWare, Inc. ("ServiceWare"). The new division will also look to other
sources such as software manufacturers, help desk and customer support
outsourcers, and Inference customers for publishable knowledge. Currently, KBI
and ServiceWare, under strategic licensing agreements with the Company, offer
pre-packaged knowledge bases pre-loaded in CBR2-readable format covering over
30 product domains that contain troubleshooting and/or problem identifications
and resolutions for particular office automation products such as Microsoft
Windows, Microsoft Word, Microsoft Excel, Lotus 1-2-3 and Lotus Notes. These
pre-packaged knowledge bases are available through the Company, as well as
through KBI and ServiceWare.
 
  The CBR2 products are offered either on a per user or per server license
basis. The current U.S. list price for an entry-level ten-user client/server
system is in the $24,000 to $50,000 range and varies depending on the number
of modules purchased. Discounts from the Company's list prices may be made
available for volume purchasers, or for competitive or strategic reasons.
 
 Future Products
 
  The Company's next generation of CBR Products, CBR3, is designed to provide
a common index and retrieval method for the wide variety of unstructured
information in help desk, customer service, human resources, and telesales and
telemarketing organizations. The CBR3 product family is designed to access and
manage four levels of unstructured information, including cases containing
experiences, solutions, and answers (e.g., how to fix a printer or which
product to recommend); document summaries and abstracts (e.g., technical notes
and product specifications); documents in a variety of formats in personal and
corporate libraries (e.g., reference manuals); and public domain and
subscription over the Internet.
 


================================================================================
     This diagram provides a triangle describing the four levels of unstructured
information discussed above. The lowest level in the triangle refers to the
specific cases of unstructured information, and each level thereafter broadens
the range of unstructured information, with the highest level referring to
public domain information available on the Internet. Each level correlates to a
Company product by arrows in the diagram.

  CBR3 includes new features including those designed to reduce the cost of
case base creation and maintenance and increase the value of summarized
documents. CBR3 is intended to broaden the scope of easily accessible
knowledge with two key additions: integration with the Topic full-text search
engine from Verity, Inc., and a new intelligent Internet meta-search and
clustering tool. In addition, CBR3 is designed to provide a set of development
kits based on a fully documented open architecture, enabling its tools to be
customized and embedded within third party customer interaction applications
and other systems.
 
  CBR3 is designed to support Microsoft Windows 95 and Windows NT, and other
operating systems and is designed to support various database management
systems, including Oracle, Informix, Sybase, Microsoft SQL Server and IBM
DB2/2. CBR3 is planned to be available in several languages. The product
family is currently in customer beta test and is scheduled to be generally
available at the end of fiscal 1997.
 
  CBR3 provides the next generation for capturing and maintaining case bases
with CBR Express Author 3.0. CBR3 introduces a visualization model of
knowledge representation that the Company believes will allow users to group
together similar content into folders and to view the topography of the
content base. CBR3 is upward compatible from CBR2.
 
  CBR3's document summarization module, CBR Express Generator 3.0, is designed
to support nine document formats. It adds conceptual hierarchy support to
generate questions more intelligently, as well as support multiple templates
for different types of questions, such as categorization and context
questions.
 
  A new three-tiered, object oriented architecture is designed to make all of
the underlying CBR technology available through a published set of application
programming interfaces (APIs), enabling OEM partners and customers to embed
both the authoring and retrieval tools of the CBR3 product line within their
applications and allow OEMs and customers to implement case-based reasoning
solutions creatively for use in many different types of applications.
 
 Services
 
  The Company has a worldwide customer services organization that provides
quality technical support and education services designed to ensure customer
success and build customer loyalty. The Company also has a worldwide
consulting services organization that assists in the development and
deployment of customer solutions. As of May 31, 1996, the Company's worldwide
customer services organization consisted of 39 employees in North America and
41 employees internationally.
 
  Consulting Services. Consultants assist customers with case base design,
review and audit and also provide technology transfer by working with a
customer's in-house staff to establish procedures for developing case bases
from existing problem identifications and resolutions. Most consulting
engagements are designed to allow the customer's staff to carry out much of
the work involved in analyzing existing customer support and internal help
desk activities and designing the case base. Consulting services are typically
priced on an hourly basis.
 
  Technical Support Options. Customers can access the Company's support
centers by telephone, fax, electronic mail, an electronic bulletin board
system and the Internet's World Wide Web. The Company typically provides
second line support for customers of its VARs, systems integrators and OEMs.
New customers receive an initial 30-day period of complimentary support after
which, for an annual fee, customers receive new software releases, upgrades,
maintenance releases and support. For example, customers with current
maintenance and support agreements will receive a free upgrade to CBR3, when
released. Depending on the chosen support plan, the fee generally ranges from
10% to 30% of the current list price of the licensed products. The Company
offers three levels of support, Basic, Gold and Platinum, each tailored to the
customers' specific requirements.
 
  Training and Education. Customers can choose from a wide variety of basic
and customized education and training programs, which are charged separately
from the Company's software products and are offered through the Company's in-
house classroom facilities in Novato, California. The Company also conducts
classes at the customer's place of business.
 
 
                                      27

  Starter "Success" Packages. Inference offers starter packages that are
designed to help customers get the most from their CBR2 products and use them
successfully. A variety of packages provide customers with the appropriate
level of consulting services and training.
 
  The Company believes that its products and services are currently priced
competitively, yet the market for products of the type developed by the Company
is highly competitive. As a result, the Company anticipates increasing pricing
pressure from current and future competitors. Any substantial downward
adjustment in the price of the Company's products or services without a
corresponding increase in unit sales would adversely affect the Company's gross
margins and could have a negative impact on the Company's business, operating
results and financial condition.
 
CUSTOMERS
 
  The Company estimates that it has granted licenses for its products to over
500 customers for use by more than 500,000 end users. In fiscal 1994 and 1996,
American Express Corporation and AT&T Corp. accounted for 14% and 11% of total
revenues, respectively. In fiscal 1995, no customer accounted for more than 10%
of the Company's total revenues.
 
  The following is a representative list of the Company's customers as of April
30, 1996. Each of the following customers has purchased at least $100,000 of
the Company's products and services since February 1, 1994:

</TABLE> 
 
  The following section presents examples of the ways in which CBR technology
can address specific business needs:
 
 Broderbund Software, Inc.
 
  Broderbund Software uses Inference's CBR technology to support their
customers who are typically home computer users often new not only to
Broderbund's software but to PCs as well. Broderbund has reduced problem
resolution times by using CBR in its support center. Recently Broderbund
provided direct customer access to its problem solving knowledge base over the
World Wide Web using Inference's CasePoint WebServer.
 
                                       28
<PAGE>
 
 NCR Corporation
 
  NCR uses Inference's CBR technology to handle 12,000 to 14,000 calls per day
from its customers requesting support. CBR has helped NCR reduce dispatching
field service representatives by 10 percent and has helped to efficiently
dispatch reps in 34 percent of the calls. The resulting cost savings have been
significant given the high call volumes at NCR.
 
 International Business Machines Corporation
 
  International Business Machines Corporation ("IBM") is using Inference's
CasePoint to provide easy-to-use technical support for software developers.
CasePoint is the engine that runs the AskPSP component of IBM's Technical
Connection Personal Software CD-ROM, which helps customers find answers to
technical questions about IBM's OS/2 Warp, PC DOS and LAN Server.
 
 Microsoft Corporation
 
  Microsoft Corporation ("Microsoft") will be using Inference's case-based
retrieval technology in future versions of its Microsoft Windows NT operating
system. The Company's technology will function within Windows NT as an
intelligent user assistant component and is being used as the foundation for
creating superior functionality in a future version of this operating system.
 
 Dun & Bradstreet Software Services, Inc.
 
  Dun & Bradstreet Software Services, Inc. ("D&B Software") uses CBR
technology to allow a new analyst, with no prior D&B Software product
experience, to provide its customers with effective 7-day/24-hour support
worldwide. CBR has helped D&B Software improve both response time and service
quality and provide improved service to its approximately 10,000 customers.
D&B Software uses CBR Express Generator to automatically index and summarize
documentation and problem resolution files from a mainframe for access by
customer support analysts using CasePoint.
 
 Freightliner Corporation
 
  Freightliner Corporation, the nation's largest heavy-duty truck
manufacturer, uses Inference's CBR technology in its ServicePro service
department software, which it supplies to its dealers and fleet customers.
ServicePro relies on CBR technology to "coach" service advisors and
technicians and help them gather information to analyze problems and isolate
probable causes. This reduces the non-productive time that dealers spend on
diagnostics and maximizes productivity in the service bay. The ServicePro
system helps dealers and fleet customers lower their overhead and improve
customer satisfaction by minimizing vehicle downtime and the cost of repairs.
 
MARKETING AND SALES
 
  The Company markets and sells its software and services in North America
through its direct sales organization, VARs, systems integrators and OEMs. The
domestic sales staff is based at the Company's corporate headquarters in
Novato, California, and in the Company's field sales offices in Atlanta,
Boston, Chicago, Dallas, Houston, Huntington Beach, McLean (Virginia), Toronto
(Canada), New Jersey, and New York. As of May 31, 1996, the North American
sales and marketing staff consisted of 40 employees.
 
  The Company maintains subsidiaries in England, Germany, France, and the
Netherlands which are responsible for the Company's activities throughout
Europe, Asia, Africa and the Middle East. As of May 31, 1996, the
international sales and marketing staff consisted of 47 employees.
International operations are subject to certain inherent risks. See "Risk
Factors--Risks Associated with International Operations."
 
                                      29
<PAGE>
 
  The Company and its indirect channel partners typically sell CBR Products
and related services through a sales representative who is assisted on an as-
needed basis by a systems engineer. To assist the sales force, the Company
utilizes a multi-tiered marketing program comprising periodic customer
communications, user conferences, advertising, public relations activities,
seminars and trade show participation.
 
  VARs, distributors, systems integrators and OEMs complement the Company's
marketing and sales organization. These entities license certain CBR Products
at a relicensing discount and may provide end users with a range of services
including training and customer service/support. There can be no assurance
that the Company can establish and maintain relationships with indirect
channel participants with the capabilities necessary to market CBR Products
effectively.
 
PARTNERING RELATIONSHIPS
 
  The Company maintains a number of relationships for the purpose of extending
both the product offerings of the Company on a stand-alone basis through
reseller agreements and the distribution of the Company's products through the
sales forces of those partners in conjunction with the sales of their own
products. Inference recently established the Inference OEM Partner Program,
which includes the following nine leading vendors: Bendata, Inc. (an Astea
International company), Datawatch Corporation (WorkGroup Systems), DKSystems
Incorporated, McAfee (Vycor), Quintus Corporation, Relational Technology
Systems, Inc., Scopus Technology, Inc., Utopia Technology Partners Inc., and
The Vantive Corporation. Each of the OEM partners has agreed to embed
Inference's CBR2 technology into their applications. The OEM Partner Program,
includes joint marketing activities, incentives for Inference's sales
professionals to work with program members and technical support to assist in
the integration process.
 
PRODUCT DEVELOPMENT
 
  The Company believes that strong development capabilities are essential to
its future performance and the maintenance of its competitive position. Since
its formation, the Company has primarily developed its technology and products
internally. The Company intends to extend its CBR product line to support
additional hardware platforms and operating systems and to develop new
facilities for authors and end users of those products. This development is
expected to include the creation of third-party applications and database
interfaces to facilitate the integration of CBR technology into customers'
environments.
 
  Although the Company has a number of ongoing development projects, its
primary product development effort is focused on CBR3 which was released in
beta form in May 1996. CBR3 will add functionality to the Company's current
product line, CBR2. There can be no assurance that the development of CBR3
will be completed successfully or on a timely basis or that the product will
include the features required to achieve market acceptance. The Company's
future operations will be substantially dependent on CBR3, and failure to
achieve market acceptance of this family of products would have a material
adverse effect on the Company's business, operating results and financial
condition. The Company has in the past experienced delays in software
development, and there can be no assurance that the Company will not
experience further delays in connection with its current product development
or future development activities. Software products as complex as those
offered by the Company may contain undetected errors when first introduced or
as new versions are released. There can be no assurance that errors will not
be found in the Company's new or enhanced products after commencement of
commercial shipments or that modifications to such products will not be
required to satisfy customer requirements, resulting in loss of or delay in
market acceptance. Delays or difficulties associated with new product
introductions or product enhancements could have a material adverse effect on
the Company's business, operating results and financial condition. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
 
                                      30
<PAGE>
 
  The Company began shipping its CasePoint WebServer product in March 1996,
which provides an Internet compatible, World Wide Web ("WWW") server with a
Mosaic-compatible, intuitive CasePoint interface. A prototype of the CasePoint
WebServer product has been available on the WWW since December 1994. CasePoint
WebServer is designed to allow the users of the WWW to be clients of any CBR2-
compatible case base or document base. By providing the WWW access to CBR
information bases, companies could implement call avoidance strategies,
allowing their customers, prospects and vendors to directly submit problems,
questions and requests; receive appropriate responses; or, if appropriate,
download entire case bases to a local computer.
 
  The Company's development organization is arranged in three groups: the
Research Group, which designs and develops technology; the Development Group,
which specifies, produces and maintains product releases; and the Quality
Assurance Group, which verifies that products meet their specifications and
the Company's quality standard. These three groups are designed to ensure that
there is an efficient separation between technology development and the time-
sensitive demands of product delivery.
 
  As of May 31, 1996, there were 27 employees on the Company's product
development staff. The total product development expenditures for the
Company's CBR Products for fiscal 1996 were $2.0 million. The Company expects
to continue to allocate significant resources to future research and
development. At present, there have been minimal capitalized software
development costs resulting from the Company's development efforts.
 
  The market for the Company's products is characterized by rapid
technological developments, evolving industry standards, swift changes in
customer requirements and frequent new product introductions and enhancements.
As a result, the Company's success depends upon its ability to continue to
enhance its existing products, develop and introduce in a timely manner new
products incorporating technological advances and respond to customer
requirements. To the extent one or more of the Company's competitors introduce
products that more fully address customer requirements, the Company's business
could be adversely affected. There can be no assurance that the Company will
be successful in developing and marketing enhancements to its existing
products or new products on a timely basis or that any new or enhanced
products will adequately address the changing needs of the marketplace. If the
Company is unable to develop and introduce new products or enhancements to
existing products in a timely manner in response to changing market conditions
or customer requirements, the Company's business, operating results and
financial condition will be materially and adversely affected. From time to
time, the Company or its competitors may announce new products, capabilities
or technologies that have the potential to replace or shorten the life cycles
of the Company's existing products. There can be no assurance that
announcements of currently planned or other new products will not cause
customers to delay their purchasing decisions in anticipation of such
products, which could have a material adverse effect on the Company's
business, operating results and financial condition. See "Risk Factors--Rapid
Technological Change; Product Transitions."
 
COMPETITION
 
  The market for customer support software is highly competitive, and there
are certain competitors with substantially greater sales, marketing,
development and financial resources than the Company. Among the Company's
major competitors in the problem identification and resolution segment of the
market are Answer Systems, Inc., Astea International Inc., Clarify, Inc. and
Software Artistry, Inc. Furthermore, many potential customers develop internal
solutions by creating business applications that eliminate the need to acquire
software and services from third-party vendors such as the Company.
 
                                      31
<PAGE>
 
  The Company believes that the competitive factors affecting the market for
the Company's products and services include vendor and product reputation;
product quality, performance and price; product functionality and features;
product scalability; product integration with other enterprise applications;
the availability of products on multiple platforms; product ease-of-use; and
the quality of customer support services, documentation and training. The
relative importance of each of these factors depends upon the specific
customer involved. There can be no assurance that the Company will be able to
compete effectively with respect to any of these factors.
 
  The Company's present or future competitors may be able to develop products
comparable or superior to those offered by the Company or adapt more quickly
than the Company to new technologies or evolving customer requirements. In
order to be successful in the future, the Company must respond to
technological change, customer requirements and competitors' current products
and innovations. In particular, while the Company is currently developing
additional product enhancements that the Company believes address customer
requirements, there can be no assurance that the Company will successfully
complete the development or introduction of these additional product
enhancements on a timely basis or that these product enhancements will achieve
market acceptance. Accordingly, there can be no assurance that the Company
will be able to continue to compete effectively in its market, that
competition will not intensify or that future competition will not have a
material adverse effect on the Company's business, operating results or
financial condition.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
  The Company's success depends in part upon its proprietary technology.
Although case-based reasoning technology is available in the public domain,
the Company believes its implementation of the CBR technology is proprietary.
The Company relies on a combination of copyright, trademark and trade secret
laws, confidentiality procedures and licensing arrangements to establish and
protect its proprietary rights. The Company does not hold any patents nor has
it obtained invention assignments from all consultants performing services for
it. Despite the precautions the Company has taken, it may be possible for an
unauthorized third party to copy or otherwise obtain and use the Company's
products, technology or other information that the Company regards as
proprietary or to develop similar products or technology independently. In
addition, effective trademark, copyright and trade secret protection may be
unavailable or limited in certain foreign countries where the Company
operates.
 
  The Company generally provides its products to end users under signed
license agreements. These agreements are negotiated with and signed by the
licensee. The Company occasionally publishes articles regarding its technical
developments in industry publications that may prevent the Company from
obtaining patent protection for ideas contained in such publications, thus
increasing the availability to third parties of fundamental aspects of the
Company's technology.
 
  The Company is not aware that any of its products infringe upon the
proprietary rights of third parties. There can be no assurance, however, that
third parties will not claim such infringement by the Company with respect to
current or future products. The Company expects that it will increasingly be
subject to such claims as the number of products and competitors in the
customer support software market grows and the functionality of such products
overlaps with other industry segments. Any such claims, whether or not they
are meritorious, could result in costly litigation or require the Company to
enter into royalty or licensing agreements. Such royalty or license
agreements, if required, may not be available on terms acceptable to the
Company or at all. If the Company were found to have infringed upon the
proprietary rights of third parties, it could be required to pay damages,
cease sales of the infringing products and redesign or discontinue such
products, any of which could have a material adverse effect on the Company's
business, operating results and financial condition.

EMPLOYEES
 
  As of May 31, 1996, the Company had a total of 222 employees, of which 114
were based in the United States, 88 in the United Kingdom, 13 in Germany, 5 in
France, and 2 in the Netherlands. Of the total, 87 were engaged in sales and
marketing, 11 were in customer support, 69 were in consulting services, 27
were in product development, and 28 were in administration and finance. The
Company's employees are not represented by any labor unions. The Company
considers its relations with its employees to be good, and there has never
been an interruption in business activities due to labor unrest. However, the
Company's future performance is contingent upon the uninterrupted service of
key technological and executive management staff and upon the maintenance of
conditions that can help attract and retain capable technicians and managers.
There is significant competition for talented and qualified employees, and
there can be no assurance that the Company will be able to retain its most
strategic employees or that it can attract and retain comparably qualified
personnel in the future.
 
LEGAL PROCEEDINGS
 
  As of the date of this Prospectus, the Company is not a party to any
material legal proceedings.
 
FACILITIES
 
  The Company's headquarters in Novato, California house product development,
sales, technical support and administrative operations in approximately 27,000
square feet of space. This facility is leased to the Company through March

the future on commercially reasonable terms as needed. The Company also leases
its various sales offices.
 
  The Company's European headquarters in Slough, England house product
development, sales, marketing, technical support and administrative operations
in approximately 14,500 square feet. This facility is under lease through
April 2000. The Company believes that the space in this location should be
adequate for its needs for the foreseeable future.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Inference Corporation
 
  We have audited the accompanying consolidated balance sheets of Inference
Corporation as of January 31, 1995 and 1996, and the related consolidated
statements of operations, cash flows and stockholders' equity for each of the
three years in the period ended January 31, 1996. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Inference
Corporation at January 31, 1995 and 1996, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
January 31, 1996, in conformity with generally accepted accounting principles.
 
                                                              Ernst & Young LLP

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               JANUARY 31, 1996
 
(INFORMATION WITH RESPECT TO THE THREE MONTHS ENDED APRIL 30, 1995 AND 1996 IS
                                  UNAUDITED)
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
 Organization
 
  Inference Corporation (the "Company") is engaged in the design, development
and marketing of software products for the customer support and service
market. The Company offers maintenance, training and consulting services in
support of its software.
 
 Consolidation
 
  The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.
 
 Foreign Currency Translation
 
  Assets and liabilities of the Company's wholly-owned foreign subsidiaries
are translated at period-end exchange rates, and revenues and expenses are
translated at the weighted average monthly exchange rates. Foreign exchange
transaction gains and losses and translation adjustments have not been
significant.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates
and assumptions that affect the amounts reported in the financial statements
and accompanying notes. Actual results could differ from those estimates.
 
 Cash equivalents and short-term investments
 
  The Company considers only those investments that are highly liquid, readily
convertible to cash and that mature within three months from the date of
purchase as cash equivalents.
 
  The Company's short-term investments are debt securities and are classified
as held-to-maturity as the Company intends and has the ability to hold the
securities to maturity. Held-to-maturity securities are stated at amortized
cost, adjusted for amortization of premiums and accretion of discounts to
maturity. Such amortization is included in interest income. At January 31,
1996, the Company's short-term investments consisted of U.S. Treasury Bills
scheduled to mature within the year. The fair value of these investments at
January 31, 1996 approximated their cost.
 
 Concentrations of Credit Risk
 
  Financial instruments which potentially subject the Company to concentration
of credit risk consist principally of cash and cash equivalents and accounts
receivable. The Company places its cash and short term investments with high
credit quality financial institutions. At times, such investments may be in
excess of the FDIC insurance limit. Concentrations of credit risk with respect
to accounts receivable are limited due to the large number of customers
comprising the Company's customer base, and their dispersion across many
different industries and geographies. Generally, the Company does not require
collateral or other security to support customer receivables. The Company
routinely assesses the financial strength of its customers and, as a
consequence, believes that its accounts receivable credit risk exposure is
limited.

                               JANUARY 31, 1996
 
(INFORMATION WITH RESPECT TO THE THREE MONTHS ENDED APRIL 30, 1995 AND 1996 IS
                                  UNAUDITED)
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
 Property and Equipment
 
  Property and equipment are recorded at cost and are depreciated using the
straight-line method over the estimated useful lives of the related assets,
ranging from one to five years, except for leasehold improvements which are
depreciated over the remaining lease term.
 
 Revenue Recognition
 
  Product revenues result principally from license agreements that provide
customers the non-exclusive right to use these products for a fixed term or on
a perpetual basis. Such revenues are recognized upon execution of a binding
agreement and delivery of the product to the customer, unless the Company has
significant future obligations to the customer, in which case revenues are
recognized when such obligations are satisfied.
 
  The Company enters into maintenance and support agreements with customers
that call for the Company to provide technical support and certain system
updates. Maintenance revenues received are deferred and recognized on a
straight-line basis over the maintenance support period. Maintenance and
support revenues are included as service revenues in the accompanying
Consolidated Statements of Operations.
 
  Service revenues result from contracts with customers for the development
and support of system applications. Service revenues are generally recognized
as the services are performed. Fixed-price service contracts are recognized on
a percentage of completion based on level of effort performed.
 
 Software Costs
 
  Capitalized software costs consist of acquired software and internal
software development costs. Software costs incurred subsequent to the
determination of the software product's technological feasibility are
capitalized. Technological feasibility is determined generally upon
availability of a working model. Capitalization ceases and amortization
commences when the software product is commercially released. Software costs
capitalized are amortized using the straight-line method over the estimated
economic life of the related product, typically three years, and are included
in cost of product revenues in the accompanying Consolidated Statements of
Operations.
 
  Capitalized software costs at January 31, 1995 and 1996 were net of
accumulated amortization of $1,051,000 and $200,000, respectively. Information
related to capitalized software costs for the three years ended January 31,
1996 was as follows:

                               JANUARY 31, 1996
 
(INFORMATION WITH RESPECT TO THE THREE MONTHS ENDED APRIL 30, 1995 AND 1996 IS
                                  UNAUDITED)
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
 Income Taxes
 
  Income taxes are accounted for using the liability method in accordance with
Statement of Financial Accounting Standard No. 109, "Accounting for Income
Taxes" (Note 4). Under this method, deferred tax liabilities and assets are
recognized for the expected future tax consequences of temporary differences
between the carrying amounts and the tax bases of assets and liabilities.
 
  The Company has not provided U.S. income taxes on the undistributed income
of its foreign subsidiaries. The cumulative amount of such income was
immaterial as of January 31, 1996.
 
 Interim Financial Data
 
  The unaudited consolidated financial statements for the three months ended
April 30, 1995 and 1996 have been prepared on the same basis as the audited
consolidated financial statements and, in the opinion of management, include
all adjustments (consisting only of normal recurring adjustments) necessary to
present fairly the financial information set forth therein, in accordance with
generally accepted accounting principles. The results of operations for the
three months ended April 30, 1996 are not necessarily indicative of the
results to be expected for the entire fiscal year.
 
 Per Share Data
 
  Net income (loss) per share is computed using the weighted average number of
shares of common stock outstanding. Common equivalent shares from convertible
preferred stock (using the if-converted method) and stock options and warrants
(using the treasury stock method) have been included in the computation when
dilutive, except as noted below. Pursuant to the Securities and Exchange
Commission Staff Accounting Bulletins, all common and common equivalent shares
issued by the Company at an exercise price below the assumed public offering
price during the twelve-month period prior to the Company's initial public
offering (completed July 1995) have been included in the calculation as if
they were outstanding for all periods presented through January 31, 1995
(using the treasury stock method at an initial public offering price of $11.00
per share for stock options and warrants and the if-converted method for
convertible preferred stock).
 
  Assuming the conversion of preferred stock did not take place in the periods
in which conversion would have an anti-dilutive impact, net loss per share
would have been $1.49 for the year ended January 31, 1994, based on 866,000
shares.
 
 Accounting for Stock-Based Compensation
 
  In October 1995, the Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation," (FAS 123) was issued and is
effective for the Company's 1997 fiscal year. The Company intends to continue
to account for employee stock options in accordance with APB Opinion No. 25
and will make the pro forma disclosures required by FAS 123 in fiscal year
1997 consolidated financial statements.
 
 
2. RELATED PARTY TRANSACTIONS
 
  The Company earned revenues on product sales and services from two
stockholders in the amounts of $1,879,000, $2,028,000 and $1,722,000, during
fiscal 1994, 1995 and 1996, respectively. At January 31, 1995 and January 31,
1996, the related accounts receivable balances from these stockholders were
$241,000 and $490,000, respectively.

3. COMMITMENTS
 
  The Company leases its facilities and certain computer equipment under
various operating leases. Total rental expense under operating leases was
approximately $1,663,000, $1,770,000 and $1,436,000 during fiscal 1994, 1995

</TABLE>
 
  Due to the uncertainties surrounding the timing of realizing the benefits of
its favorable tax attributes in future tax returns, the Company has placed a
valuation allowance against its otherwise recognizable deferred tax assets.
The valuation allowance decreased by approximately $176,000 and $1,242,000
during the years ended January 31, 1995 and 1996, respectively.
 
  At January 31, 1996, the Company has net operating loss carryforwards for
federal income tax purposes of approximately $16,300,000 which expire in
various years through 2009 and net operating loss carryforwards for state
income tax purposes of approximately $1,400,000 which expire in various years
through 1999. The Company also has general business credits of approximately
$1,109,000 which expire in various years through 2009.
 
  Deferred tax assets relating to net operating loss carryforwards as of
January 31, 1996 include approximately $187,000 associated with stock option
activity for which any subsequent recognized tax benefits will be credited
directly to stockholders equity.
 
  Due to the "change in ownership" provisions of the Tax Reform Act of 1986,
utilization of the Company's net operating loss carryforwards and research and
development credit carryforwards may be subject to a substantial limitation if
a greater than 50% ownership change were to occur in the future.

5. REORGANIZATION AND DIVESTITURE OF BUSINESS UNIT
 
  From May 1991 through April 30, 1995, the Company's revenues were derived
from two separate product lines: (i) the customer support product line,
consisting of the CBR Express family of products and associated services (the
"CBR Business") and (ii) the application development and solutions product
line, which included the Company's products: ART, ART-IM and ART*Enterprise
("Tools") and associated services (the "Tools Business"). In the fourth
quarter of fiscal 1995, the Company made a strategic decision to focus on the
CBR Business and to divest the Tools Business. Effective May 1, 1995, the
Company transferred certain assets and liabilities of the Tools Business to a
wholly-owned subsidiary of the Company and distributed all of the shares of
such subsidiary to the Company's stockholders (the "Spin-Off"). As part of the
Spin-Off, the Company entered into an agreement (the "Administrative Services
Agreement") with the Tools Business to provide certain services to the new
entity including operational and systems support, facilities and
administrative support and certain technical and customer support. This
agreement expired on January 31, 1996. The amount received for these services
was approximately $760,000 and was accounted for as an offset against
expenses.
 
  Revenues for the Tools Business were $1,928,000 for the three months ended
April 30, 1995. The following table summarizes the components of the
identifiable net assets transferred to the Tools Business (in thousands):

6. NON-RECURRING EXPENSE
 
  During fiscal 1995, the Company invested in the development of a new
business concept unrelated to its current businesses or product groups,
managed by the Company's former Chairman of the Board of Directors. In
November 1994, the Company made a strategic decision to discontinue its
efforts in this area and in May 1995 licensed this technology to a newly
formed company in which the Company was issued an equity interest. The Company
has recorded no value related to this equity interest. In connection with the
strategic decision, the Company entered into a severance agreement with the
former Chairman of the Board of Directors effective February 28, 1995, which
provided for the continuation of his monthly salary through April 30, 1995.
Costs associated with the severance agreement, as well as other costs
(principally salaries and related expenses) incurred related to this
discontinued business venture have been recorded in fiscal 1995 as a non-
recurring expense in the accompanying Consolidated Statements of Operations.
In addition, non-recurring expense also includes approximately $200,000
accrued in the fourth quarter of fiscal 1995 for lease payments associated
with the early termination of the Company's European headquarters facility
lease.

7. CAPITAL STRUCTURE
 
 Initial Public Offering
 
  In July 1995, the Company completed an initial public offering of 2,130,000
shares of unissued Class A Common Stock and 400,000 shares of outstanding
common stock that were offered by certain selling stockholders. The Company
received approximately $20 million after deducting expenses and underwriting
discounts and commissions.
 
  The Company's Board of Directors also approved a one-for-five reverse stock
split of the Company's common stock and convertible preferred stock, which was
effected prior to the Company's initial public offering.
 
 Common Stock
 
  The Common Stock consists of two classes, Class A Common Stock and Class B
Common Stock. At January 31, 1996 there were 6,290,000 shares of Class A
Common Stock and 1,190,000 shares of Class B Common Stock outstanding. This
gives effect to the conversion of all Class A, Class B, Class C, Class D,
Class F, Class G, Class H and Class I Preferred Stock into Common Stock in
conjunction with the Company's initial public offering in July 1995.
 
  Class A Common Stock. The holders of the Class A Common Stock are entitled
to one vote per share on all matters submitted to a vote of the stockholders.
The holders of shares of Class A Common Stock do not have any preemptive
rights or rights to subscribe for additional securities of the Company.
Dividends are payable on the Class A Common Stock, when, as and if declared by
the Board of Directors out of funds legally available therefor. Each share of
Common Stock, irrespective of class, will be treated equally in respect of
rights upon liquidation of the Company and rights to dividends, except that,
in the case of dividends in the form of Common Stock, shares of any class of
Common Stock will be payable only to the holders of that class. Upon
liquidation or dissolution of the Company, the holders of the Class A Common
Stock and Class B Common Stock are entitled to share ratably in all assets
available for distribution to stockholders after payment of all prior claims.
 
  Class B Common Stock. The rights of the holders of the Class B Common Stock
are identical to those of the Class A Common Stock except with respect to
voting and conversion rights. The holders of Class B Common Stock have no
right to vote on matters submitted to a vote of stockholders, except (i) as to
an amendment of a provision of the Restated Articles of Incorporation that
adversely affects the powers, preferences or special rights of the holders of
the Class B Common Stock and (ii) as otherwise required by law. Holders may
convert shares of Class B Common Stock into Class A Common Stock, except that
no holder of shares of Class B Common Stock may convert any such shares to the
extent that, as a result, the holder and its affiliates, directly or
indirectly, would own, control or have the power to vote more than 5% of the
outstanding shares of the Common Stock. A holder of Class A Common Stock also
may convert its Class A Common Stock into Class B Common Stock. Each
conversion will be on a one-for-one basis.

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.
 
 Stock Warrants
 
  At January 31, 1996, there were outstanding warrants to purchase 185,000
shares of common stock at an average purchase price of approximately $5.00.
Warrants covering approximately 159,000 shares of common stock expire in

8. STOCK OPTION PLANS
 
  The Company has authorized stock option plans that cover the issuance of
incentive stock options and non-statutory stock options. The plans provide for
the granting of options for the purchase of up to 1,600,000 authorized but
unissued shares of the Company's common stock. There were 196,000 shares
available for future option grants under the plan as of January 31, 1996.
Under the terms of the plan, options may be granted to employees, non-employee
directors or consultants at prices not less than the fair value at the date of

 9. EMPLOYEE BENEFIT PLANS
 
  The Company sponsors an employee savings and retirement plan (the "401(k)
Plan") as allowed under Section 401(k) of the Internal Revenue Code. The
401(k) Plan is available to all domestic employees who meet minimum age and
service requirements, and provides employees with tax deferred salary
deductions and alternative investment options. Employees may contribute up to
20% of their salary, subject to certain limitations. The 401(k) Plan allows
for contributions by the Company at the discretion of the Company's Board of
Directors. The Company has not contributed to the 401(k) Plan.
 
  The Company also sponsors a voluntary defined contribution retirement plan
(the "UK Plan") for employees in the United Kingdom. Employees may elect to
contribute a percentage of their annual gross compensation to the UK Plan.
Employer contributions to the UK Plan range between 5% to 12% of participating
employees' base salary, depending on the years of experience with the Company.
Contributions to the plan were $137,000, $207,000, and $272,000 for the fiscal

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                               JANUARY 31, 1996
 
(INFORMATION WITH RESPECT TO THE THREE MONTHS ENDED APRIL 30, 1995 AND 1996 IS
                                  UNAUDITED)
 
11. NON-EMPLOYEE STOCK OPTION RELATED EXPENSES
 
  During the three months ended April 30, 1996, the Company incurred payroll-
related taxes as a result of the exercise of non-qualified stock options held
by former employees. This one-time charge amounted to $215,000 and has been
accounted for separate from operating income. In connection with these option
exercises, the Company will be able to take a tax deduction, if and when
adequate taxable income is earned, of approximately $7,500,000 for
compensation expense; this tax benefit, however, will be accounted for when
utilized as an adjustment to stockholders' equity.
 
12. SUBSEQUENT EVENTS
 
 Reincorporation in Delaware
 
  In May 1996, the Company's Board of Directors approved the reincorporation
of the Company in Delaware. The reincorporation was approved by the Company's
stockholders in July 1996; however, this change has not been reflected in the
accompanying consolidated financial statements. The Company's Board of
Directors will have the authority to issue up to 15,000,000 shares of Class A
Common Stock, par value $0.01 per share, 2,000,000 shares of Class B Common
Stock, par value $0.01 per share, and 2,000,000 shares of Preferred Stock, par
value $0.01 per share. The price, rights, preferences and privileges of the
unissued Preferred Stock are determined at the discretion of the Board of
Directors.
 
 Employee Stock Purchase Plan
 
  The Inference Corporation Employee Stock Purchase Plan (the "Purchase Plan")
was adopted by the Company's Board of Directors in May 1995 and approved by
the Company's stockholders in July 1996. A total of 500,000 shares of Common
Stock have been reserved for issuance under the Purchase Plan. The Purchase
Plan will enable eligible employees to purchase Common Stock at 85% of the
lower of the fair market value of the Company's Common Stock on the first day
or the last day of each purchase period.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company's Certificate of Incorporation provides that to the fullest
extent permitted by Delaware Law, a director of the Company shall not be
liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director. Under current Delaware Law, liability of a
director may not be limited (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or that involve intentional misconduct or a knowing violation of
law, (iii) in respect of certain unlawful dividend payments or stock
redemptions or repurchases and (iv) for any transaction from which the
director derives an improper personal benefit. The effect of such provision in
the Company's Certificate of Incorporation is to eliminate the rights of the
Company and its stockholders (through stockholders' derivative suits on behalf
of the Company) to recover monetary damages against a director for breach of
the fiduciary duty of care as a director (including breaches resulting from
negligent or grossly negligent behavior), except in the situations described
in clauses (i) through (iv) above. This provision does not limit or eliminate
the rights of the Company or any stockholder to seek nonmonetary relief such
as an injunction or rescission in the event of a breach of a director's duty
of care. In addition, the Company's Bylaws provide that the Company shall
indemnify its directors, officers, employees and agents against losses
incurred by any such person by reason of the fact that such person was acting
in such capacity.
 
  The Company has entered into agreements (the "Indemnification Agreements")
with each of the directors and officers of the Company pursuant to which the
Company has agreed to indemnify such director or officer from claims,
liabilities, damages, expenses, losses, costs, penalties or amounts paid in
settlement incurred by such director or officer in or arising out of his or
her capacity as a director, officer, employee and/or agent of the Company or
any other corporation of which he or she is a director or officer at the
request of the Company to the maximum extent provided by applicable law. In
addition, such director or officer is entitled to an advance of expenses to
the maximum extent authorized or permitted by law.
 
  To the extent that the Board of Directors or the stockholders of the Company
may in the future wish to limit or repeal the ability of the Company to
provide indemnification as set forth in the Company's Certificate of
Incorporation, such repeal or limitation may not be effective as to directors
and officers who are currently parties to the Indemnification Agreements,
because their rights to full protection would be contractually assured by the
Indemnification Agreements. It is anticipated that similar contracts may be
entered into, from time to time, with future directors and officers of the
Company. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company, the Company 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.

  Reference is also made to Section 11 of the Underwriting Agreement contained
in Exhibit 1.1 hereto, indemnifying officers and directors of the Registrant
against certain liabilities, Section 2.05 of the Master Registration Rights
Agreement contained in Exhibit 4.2 hereto and Section 4.1 of the Second
Amended and Restated Demand Registration Right Agreement contained in Exhibit
4.3 hereto, both indemnifying certain of the Company's stockholders including
controlling stockholders, against certain liabilities. Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Company, the
Company 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.

ITEM 17. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the Delaware General Corporation Law, the Certificate
of Incorporation or the Bylaws of the registrant, the Underwriting Agreement,
or otherwise, the 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 the registrant of expenses incurred or paid by a director,
officer, or controlling person of the 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
hereunder, the 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 of 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.

interests of each of such corporations that Inference California merge with and
into Inference Delaware upon the terms and subject to the conditions set forth
in this Agreement for the purpose of effecting the change of the state of
incorporation of Inference California from California to Delaware;

     WHEREAS, the respective Boards of Directors of Inference California and
Inference Delaware have, by resolutions duly adopted, approved this Agreement;

     WHEREAS, Inference California has approved this Agreement as the sole

     WHEREAS, the shareholders of Inference California have approved this

     NOW, THEREFORE, in consideration of the mutual agreements and covenants set
forth herein, Inference California and Inference Delaware hereby agree as
follows:

     1.   Merger.  Subject to the conditions of this Agreement, Inference
California shall be merged with and into Inference Delaware (the "Merger"), and
Inference Delaware shall be the surviving corporation (hereinafter sometimes
referred to as the "Surviving Corporation").  The Merger shall become effective
upon the date and at the time of filing of a copy of this Agreement of Merger
with appropriate certificates of merger, providing for the Merger, with the
Secretary of State of the State of California or an appropriate Certificate of
Merger, providing for the Merger, with the Secretary of State of the State of
Delaware, whichever later occurs (the "Effective Time").
<PAGE>
 
     2.  Governing Documents.  The Certificate of Incorporation of Inference
Delaware, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation without change or
amendment until thereafter amended in accordance with the provisions thereof and
applicable laws, except that the Certificate of Incorporation shall hereby be
amended to change the name of the Surviving Corporation to "Inference
Corporation," and the Bylaws of Inference Delaware, as in effect immediately
prior to the Effective Time, shall be the Bylaws of the Surviving Corporation
without change or amendment until thereafter amended in accordance with the
provisions thereof, of the Certificate of Incorporation of the Surviving
Corporation and applicable law.

     3.   Succession.  At the Effective Time, the separate corporate existence
of Inference California shall cease, and Inference Delaware shall possess all
the rights, privileges, powers and franchises of a public and private nature and
be subject to all the restrictions, disabilities and duties of each of the
Constituent Corporations; and all and singular, the rights, privileges, powers
and franchises of each of the Constituent Corporations, and all property, real,
personal and mixed, and all debts due to each of the Constituent Corporations on
whatever account, as well for stock subscriptions as all other things in action
belonging to each of the Constituent Corporations, shall be vested in the
Surviving Corporation; and all property, rights, privileges, powers and
franchises, and all and every other interest shall be thereafter as effectually
the property of the Surviving Corporation as they were of the respective
Constituent Corporations, and the title to any real estate vested by deed or
otherwise, in either of such Constituent Corporations shall not revert or be in
any way impaired by reason of the Merger; but all rights of creditors and all
liens upon any property of Inference California shall be preserved unimpaired.
To the extent permitted by law, any claim existing or action or proceeding
pending by or against either of the Constituent Corporations may be prosecuted
as if the Merger had not taken place.  All debts, liabilities and duties of the
respective Constituent Corporations shall thenceforth attach to the Surviving
Corporation and may be enforced against it to the same extent as if such debts,
liabilities and duties had been incurred or contracted by it.  All corporate
acts, plans, policies, agreements, arrangements, approvals and authorizations of
Inference California, its shareholders, Board of Directors and committees
thereof, officers and agents which were valid and effective immediately prior to
the Effective Time, shall be taken for all purposes as the acts, plans,
policies, agreements, arrangements, approvals and authorizations of the
Surviving Corporation and shall be as effective and binding thereon as the same
were with respect to Inference California.  The employees and agents of
Inference California shall become the employees and agents of the Surviving
Corporation and continue to be entitled to the same rights and benefits which
they enjoyed as employees and agents of Inference California.  The requirements
of any plans or agreements of Inference California involving the issuance or
purchase by Inference California of certain shares of its capital stock shall be
satisfied by the issuance or purchase of a like number and same class of shares
of the Surviving Corporation.

     4.   Directors and Officers.  The Directors and Officers of Inference
California on the Effective Time shall be and become the sole Directors and
Officers, holding the same titles and positions, of the Surviving Corporation on
the Effective Time, and after the Effective Time shall serve in accordance with
the Bylaws of the Surviving Corporation.

     5.   Further Assurances.  From time to time, as and when required by the
Surviving Corporation or by its successors or assigns, there shall be executed
and delivered on behalf of Inference California such deeds and other
instruments, and there shall be taken or caused to be taken by it all such
further and other action, as shall be appropriate, advisable or necessary in
order to vest, perfect or confirm, of record or otherwise, in the Surviving
Corporation the title to and possession of all property, interests, assets,
rights, privileges, immunities, powers, franchises and authority of Inference
California, and otherwise to carry out the purposes of this Agreement, and the
officers and directors of the Surviving Corporation are fully authorized in

                                       2

the name and on behalf of Inference California or otherwise, to take any and all
such action and to execute and deliver any and all such deeds and other
instruments.

     6.  Conversion of Shares.  At the Effective Time, by virtue of the Merger
and without any action on the part of the holder thereof:

          (a) each share of California Class A Common Stock outstanding
     immediately prior to the Effective Time shall be changed and converted into

          (b) each share of California Class B Common Stock outstanding
     immediately prior to the Effective Time shall be changed and converted into

     Class A Common Stock, and no shares of Delaware Common Stock or other
     securities of Inference Delaware shall be issued in respect thereof.

     8.   Stock Certificates.  At and after the Effective Time, all of the

registered owner on the books and records of the Surviving Corporation or its
transfer agents of any such outstanding stock certificate shall, until such
certificate shall have been surrendered for transfer or otherwise accounted for
to the Surviving Corporation or its transfer agents, have and be entitled to
exercise any voting and other rights with respect to, and to receive any
dividends and other distributions upon, the shares of Delaware capital stock
evidenced by such outstanding certificate as above provided.

the principal terms of this Agreement of Merger.

     12.  Abandonment.  At any time prior to the Effective Time, this Agreement
may be terminated and the Merger may be abandoned by the Board of Directors of
Inference California, notwithstanding approval of this Agreement by the
stockholder of Inference Delaware or by the shareholders of Inference

     any time and from time to time, any or all of the shares of Class A Common
     Stock held by such stockholder into the same number of shares of Class B
     Common Stock.  The term "Regulated Stockholder" shall mean (a) any
     stockholder that is a Federal licensee under the Small Business Investment
     Act of 1958 or that is subject to the provisions of Regulation Y of the
     Board of Governors of the Federal Reserve System (12 C.F.R. Part 225) or

     December 1, 1996 ("SUBJECT DATE") or upon exercise of warrants or options
     that were outstanding on or prior to the Subject Date, or shares issued
     upon conversion(s) of such shares, so long as such stockholder shall hold
     any such shares of Class A Common Stock or Class B Common Stock or shares
     issued upon conversion(s) of such shares, (b) any Affiliate (as defined
     below) of any such Regulated Stockholder specified in clause (a) above that
     is a transferee of any shares of Class A Common Stock or Class B Common
     Stock of the Corporation, so long as such Affiliate shall hold any such
     shares of Class A Common Stock or Class B Common Stock or shares issued
     upon conversion(s) of such shares and (c) any individual, partnership,
     joint venture, corporation, association, trust, or any other entity or
     organization, including a government or political subdivision or an agency
     or instrumentality thereof (a "PERSON") (i) to which any such Regulated
     Stockholder specified in clause (a) above or any of its Affiliates has
     transferred such shares, so long as such transferee shall hold, and only
     with respect to, any shares transferred by such Regulated Stockholder or
     Affiliate or any shares issued upon conversion(s) of such shares, and (ii)
     which transferee is, or any Affiliate of which is, subject to the
     provisions of Regulation Y.  As used in this Certificate of Incorporation,
     the term "AFFILIATE" shall mean with respect to any Person, any other
     Person directly or indirectly controlling, controlled by or under common
     control with such Person.  For the purpose of this definition, the term
     "CONTROL" (including with correlative meanings, the terms "CONTROLLING",
     "CONTROLLED BY" and "UNDER COMMON CONTROL WITH"), as used with respect to
     any Person, shall mean the possession, directly or indirectly, of the power
     to direct or cause the direction of the management and policies of such
     Person, whether through the ownership of voting securities or by contract
     or otherwise.

     (2) Upon compliance with the provisions of paragraph (D)(3) below, any
     stockholder shall be entitled to convert, at any time and from time to
     time, any and all shares of Class B Common Stock held by such stockholder
     into the same number of shares of Class A Common Stock; provided, however,
                                                             --------  ------- 
     that no holder of any shares of 

                                       3
<PAGE>
 
     Class B Common Stock that is a Regulated Stockholder shall be entitled to
     convert any such shares into shares of Class A Common Stock, to the extent
     that, as a result of such conversion, such holder and its Affiliates,
     directly or indirectly, would own, control or have the power to vote more
     than five percent (5%) of the outstanding shares of Class A Common Stock.

          (3)(a) Each conversion of Common Shares into another class of Common
     Shares shall be effected by the surrender of the certificate(s) evidencing
     the shares of the class of stock to be converted (the "CONVERTING SHARES")
     at the principal office of the Corporation (or such other office or agency
     of the Corporation as the Corporation may designate by notice in writing to
     the holders of Common Shares) at any time during its usual business hours,
     together with written notice by the holder of such Converting Shares, (i)
     stating that the holder desires to convert the Converting Shares or a
     specified number of such Converting shares, evidenced by such
     certificate(s) into an equal number of shares of the class into which such
     shares may be converted (the "CONVERTED SHARES"), and (ii) giving the
     name(s) (with addresses) and denominations in which the certificate(s)
     evidencing the Converted Shares shall be issued, and instructions for the
     delivery thereof.  The Corporation shall promptly notify each stockholder
     of record of its receipt of such notice.  Upon receipt of the notice
     described in the first sentence of this paragraph (D)(3)(a), together with
     the certificate(s) evidencing the Converting Shares, the Corporation shall
     be obligated to, and shall, issue and deliver in accordance with such
     instructions the certificate(s) evidencing the Converted Shares issuable
     upon such conversion and a certificate (which shall contain such legends,
     if any, as were set forth on the surrendered certificate(s)) representing
     any shares which were represented by the certificate(s) surrendered to the
     Corporation in connection with such conversion but which were not
     Converting Shares and, therefore, were not converted; provided, however,
                                                           --------  ------- 
     that if such conversion is subject to paragraph (D)(3)(c) below, the
     Corporation shall not issue said certificate(s) until the expiration of the
     Deferral Period referred to therein.  Such conversion shall be deemed to
     have been effected as of the close of business on the date on which such
     certificate(s) shall have been surrendered and such written notice shall
     have been received by the Corporation, and at such time the rights of the
     holder of such Converting Shares as such holder shall cease (except that in
     the case of a conversion subject to paragraph (D)(3)(c) below, the
     conversion shall be deemed effective upon expiration of the Deferral Period
     referred to therein), and the person(s) in whose name or names any
     certificate(s) evidencing the Converted Shares are to be issued upon such
     conversion shall be deemed to have become the holder(s) of record of the
     Converted Shares.

          (b) Upon the issuance of the Converted Shares in accordance with this
     paragraph (D), such shares shall be deemed to be duly authorized, validly
     issued, fully paid and non-assessable.

          (c) The Corporation shall not convert or directly or indirectly
     redeem, purchase or otherwise acquire any shares of Class A Common Stock or
     take any other

                                       4
<PAGE>
 
     action affecting the voting rights of such shares, if such action will
     increase the percentage of outstanding voting securities owned or
     controlled by any Regulated Stockholder (other than the stockholder which
     requested that the Corporation take such action, or which otherwise waives
     in writing its rights under this paragraph (D)) unless the Corporation
     gives written notice (the "FIRST NOTICE") of such action to each such
     holder. The Corporation will defer making any conversion, redemption,
     purchase or other acquisition or taking any such other action for a period
     of 30 days (the "DEFERRAL PERIOD") after giving the First Notice in order
     to allow each such holder to determine whether it wishes to convert or take
     any other action with respect to the Common Shares it owns, controls or has
     the power to vote, and if any such holder then elects to convert any shares
     of Class A Common Stock, it shall notify the Corporation in writing within
     20 days of the issuance of the First Notice, in which case the Corporation
     (i) shall promptly notify from time to time each other Regulated
     Stockholder holding shares of each proposed conversion and the proposed
     transactions, and (ii) effect the conversion requested by each holder of
     Class B Common Stock in response to the notices issued pursuant to this
     paragraph (D)(3)(c) at the end of the Deferral Period or as soon thereafter
     as is reasonably practicable.

          (d) The Corporation will at all times reserve and keep available out
     of its authorized but unissued shares of Class A Common Stock and Class B
     Common Stock or its treasury shares, solely for the purpose of issue upon
     conversion of shares of Class A Common Stock and Class B Common Stock, such
     number of shares of such class as shall then be issuable upon the
     conversion of all outstanding shares of Class A Common Stock and Class B
     Common Stock.

          (e) The issue of certificates evidencing shares of any class of Common
     Shares upon conversion of shares of any other class of Common Shares shall
     be made without charge to the holders of such shares for any issue tax in
     respect thereof or other cost incurred by the Corporation in connection
     with such conversion; provided, however, the Corporation shall not be
                           --------  -------                              
     required to pay any tax that may be payable in respect of any transfer
     involved in the issuance and delivery of any certificate in a name other
     than that of the holder of the Common Shares converted.

          (4) If the Corporation shall in any manner subdivide (by stock split,
     stock dividend or otherwise) or combine (by reverse stock split or
     otherwise) the outstanding shares of the Class A Common Stock or the Class
     B Common Stock, the outstanding shares of each other class of Common Shares
     shall be proportionately subdivided or combined, as the case may be, and
     effective provision shall be made for the protection of all conversion
     rights hereunder. In case of any reorganization, reclassification or change
     of shares of Class A Common Stock or Class B Common Stock, or in case of
     any consolidation of the Corporation with one or more other corporations or
     a merger of the Corporation with another corporation (other than a merger
     in which the Corporation is the continuing corporation and which does not
     result in any reclassification or change of outstanding shares of Class A
     Common Stock or Class B Common Stock), or in case of

                                       5
<PAGE>
 
     any sale, lease or other disposition to another corporation (other than a
     wholly-owned subsidiary of the Corporation) of all or substantially all the
     assets of the Corporation, each holder of Common Shares, irrespective of
     class, shall have the right at any time thereafter, so long as the
     conversion right hereunder with respect to such Common Shares would exist
     had such event not occurred, to convert such shares into the kind and
     amount of shares of stock and other securities and property (including
     cash) receivable upon such reorganization, reclassification, change,
     consolidation, merger, sale, lease or other disposition by a holder of the
     number of shares of the class of Common Shares into which such Common
     Shares might have been converted immediately prior to such reorganization,
     reclassification, change, consolidation, merger, sale, lease or other
     disposition. In the event of such a reorganization, reclassification,
     change, consolidation, merger, sale, lease or other disposition, effective
     provision shall be made in the Certificate of Incorporation of the
     resulting or surviving corporation or otherwise for the protection of the
     conversion rights of the Common Shares of each class that shall be
     applicable, as nearly as reasonably may be, to any such other shares of
     stock and other securities and property deliverable upon conversion of
     Common Shares into which such Common Shares might have been converted
     immediately prior to such event. The Corporation shall not be a party to
     any merger, consolidation or recapitalization pursuant to which any
     Regulated Stockholder would be required to take (i) any voting securities
     which would cause such holder to violate any law, regulation or other
     requirement of any governmental body applicable to such Regulated
     Stockholder, or (ii) any securities convertible into voting securities
     which if such conversion took place would cause such holder to violate any
     law, regulation or other requirement of any governmental body applicable to
     such Regulated Stockholder other than securities which are specifically
     provided to be convertible only in the event that such conversion may occur
     without any such violation.

          SECTION 2.  Preferred Stock.  The Board of Directors is authorized,
                      ---------------                                        
subject to the limitations prescribed by law and the provisions of Section 2 of
this Article IV, to provide for the issuance of shares of Preferred Stock from
time to time in one or more series, and by filing any certificate of
designations required under Section 151(g) of the Delaware General Corporation
Law (or its successor statute as in effect from time to time), to fix or alter
the number of shares of any series of Preferred Stock, and to fix the powers,
designations, preferences and relative, participating, optional or other rights,
and the qualifications, limitations or restrictions granted to or imposed upon
the shares of any wholly unissued series of Preferred Stock. The authority of
the Board of Directors with respect to each series shall include, but not be
limited to, the determination of the following:

          (a) the number of shares constituting and the distinctive designation
     of such series;

          (b) the dividend rights of the shares of such series, including
     whether dividends shall be cumulative and, if so, from which date or dates,
     and the 

                                       6
<PAGE>
 
     relative rights of priority, if any, of payment of dividends on shares of
     such series;

          (c) whether such series shall have voting rights, and, if so, the
     terms of such voting rights, including the number of votes per share, the
     number of members of the Board of Directors or the percentage of members of
     the Board of Directors each class or series of Preferred Stock may be
     entitled to elect;

          (d) whether such series shall have conversion rights and, if so, the
     terms and conditions of such conversion, including provision for adjustment
     of the conversion rate in such events as the Board of Directors shall
     determine;

          (e)  whether or not the shares of such series shall be redeemable,
     and, if so, the terms and conditions of such redemption, including the date
     or date upon or after which they shall be redeemable, and the amount per
     share payable in case of redemption, which amount may vary as the Board of
     Directors determines under different conditions and at different redemption
     dates;

          (f) whether such series shall have a sinking fund for the redemption
     or purchase of shares of such series, and, if so, the terms and amount of
     such sinking fund;

          (g) the rights of the shares of such series in the event of voluntary
     or involuntary liquidation, dissolution or winding up of the Corporation,
     and the relative rights of priority, if any, of payment of shares of such
     series; and

          (h) any other relative rights, preferences and limitations of such
     series.

          The Board of Directors may, within the limits and restrictions stated
in any resolution or resolutions of the Board of Directors originally fixing the
number of shares constituting any series, increase or decrease (but not below
the number of shares of such series then outstanding) the number of shares of
any such series subsequent to the issue of shares of that series. Preferred
Shares that are redeemed, purchased or otherwise acquired by the Corporation may
be reissued except as otherwise provided by law or the applicable certificate of
designations.

ARTICLE VI.  BOARD OF DIRECTORS.
             ------------------ 

          SECTION 1.  Number of Directors.  The properties, business and affairs
                      -------------------                                       
of the Corporation shall be managed and controlled by a Board of Directors of
not less than five (5) nor more than eleven (11) members.  The number of
directors which shall constitute the whole Board of Directors shall be six (6)
unless and until otherwise determined in the manner provided in the Bylaws of
the Corporation.  Notwithstanding any other provision of this Article VI, and
except as otherwise required by law, whenever the holders of any one or more
series of Preferred Stock or other securities of the Corporation shall have the
right, voting separately as a class, to elect one or more directors of the
Corporation, such directorship or directorships shall be in addition to the
number of directors as determined in the manner provided in the Bylaws of the
Corporation, such director or directors shall not be classified pursuant to
Section 2 of this Article VI, and, unless otherwise provided by law or by
resolution of the Board of Directors authorizing such series of Preferred Stock
or other securities of the Corporation, the filling of vacancies and other
features of any such directorship shall be governed by the terms of this
Certificate of Incorporation applicable thereto, except that, unless otherwise
provided by law or by resolution of the Board of Directors authorizing such
series of Preferred Stock or other securities of the Corporation, any such
director shall hold office for a term expiring at the next succeeding annual
meeting of stockholders and until such director's successor shall be elected and
qualified, or until such director's death, resignation or removal, whichever
occurs earlier.

          SECTION 2.  Classified Board -- Three Classes.  The directors, other
                      ---------------------------------                       
than those directors not classified pursuant to Section 1 of this Article VI,
shall be divided into three (3) classes, designated Class I, Class II and Class
III, such classes to be as nearly equal in number as possible.  Each director of
Class I shall hold office for a term expiring at the next annual meeting of
stockholders and until such director's successor is duly elected and qualified,
or until such director's earlier death, resignation or removal, each director of
Class II shall hold office for a term expiring at the second annual meeting of
stockholders and until such director's successor is duly elected and qualified,
or until such director's earlier death, resignation or removal, and each
director of Class III shall hold office for a term expiring at the third annual
meeting of stockholders and until such director's successor is duly elected and
qualified, or until such director's earlier death, resignation or removal.
Thereafter, at each annual meeting of stockholders, directors shall be chosen
for a term of three years to succeed those whose terms then expire and shall
hold office until the third annual meeting of stockholders following the annual
meeting of stockholders at which each such director was elected and until such
director's successor is duly elected and qualified, or until such director's
earlier death, resignation or removal.

          SECTION 3.  Board Reclassification.  Unless otherwise agreed to by a
                      ----------------------                                  
two-thirds majority of the existing directors, the determination of the
selection of directors in each class upon changes in the number of directors
shall be determined in the manner provided in the Bylaws of the Corporation.

<PAGE>
 
          SECTION 4.  Vacancies.  Any vacancy on the Board of Directors for any
                      ---------                                                
reason, whether arising through death, resignation or removal of a director or
through an increase in the number of directors of any class, shall be filled by
a majority vote of the remaining directors, although less than a quorum, or by a
sole remaining director.  The term of office of any director elected to fill
such a vacancy shall, except as provided in Section 3 of this Article VI, expire
at the expiration of the term of office of directors of the class in which the
vacancy occurred.

          SECTION 5.  Elections.  Elections of directors need not be by written
                      ---------                                                
ballot except and to the extent provided in the Bylaws of the Corporation.

          SECTION 6.  Stockholder Nominees.  Nominations by stockholders of
                      --------------------                                 
persons for election to the Board of Directors shall be made only in accordance
with the procedures set forth in the Bylaws of the Corporation.

          SECTION 7.  Removal.  Subject to the rights of the holders of any
                      -------                                              
series of Preferred Stock then outstanding, any director, or the entire Board of
Directors, may be removed from office at any time, but only for cause.
Notwithstanding the foregoing, and except as otherwise required by law, whenever
the holders of any one or more series of Preferred Stock shall have the right,
voting separately as a class, to elect one or more directors of the Corporation,
the provisions of this Section 7 shall not apply with respect to such director
or directors.

ARTICLE VII.  BYLAWS.
              ------ 

          A majority of the Board of Directors is expressly authorized to make,
alter, amend or repeal the Bylaws of the Corporation.  The stockholders of the
Corporation may adopt, amend or repeal Bylaws of the Corporation.

ARTICLE VIII.  STOCKHOLDER MEETINGS; BOOKS.
               --------------------------- 

          Meetings of stockholders shall be held at such time, on such date and
at such place (within or without the State of Delaware) as provided in the
Bylaws of the Corporation.  Any action required or permitted to be taken by the
stockholders of the Corporation must be taken at a duly called and noticed
meeting of stockholders and may not be taken by consent in writing. The books of
the Corporation may be kept, subject to any applicable statutory provision,
outside the State of Delaware at such place or places as may be designated from
time to time by the Board of Directors or in the Bylaws of the Corporation.

ARTICLE IX. DIRECTOR LIABILITY; INDEMNIFICATION.
            ----------------------------------- 

          To the fullest extent permitted by the General Corporation Law of the
State of Delaware as the same exists or may hereafter be amended, a director of
the Corporation shall not be liable to the Corporation or its 

                                       9
<PAGE>
 
stockholders for monetary damages for breach of fiduciary duty as a director.
The liability of a director of the Corporation to the Corporation or its
stockholders for monetary damages shall be eliminated to the fullest extent
permissible under applicable law in the event it is determined that Delaware law
does not apply. The Corporation is authorized to provide by bylaw, agreement or
otherwise for indemnification of directors, officers, employees and agents for
breach of duty to the Corporation and its stockholders to the fullest extent
permitted by applicable law. Any repeal or modification of this Article IX shall
not result in any liability for a director with respect to any action or
omission occurring prior to such repeal or modification.

ARTICLE X. AMENDMENTS.
           ---------- 

          The Corporation reserves the right to amend this Certificate of
Incorporation in any manner permitted by the Delaware General Corporation Law
and all rights and powers conferred upon stockholders, directors and officers
herein are granted subject to this reservation.  Notwithstanding the foregoing,
the provisions set forth in Articles VI, VIII, IX and this Article X may not be
repealed or amended in any respect, and no other provision may be adopted,
amended or repealed which would have the effect of modifying or permitting the
circumvention of the provisions set forth in Articles VI, VIII, IX and this
Article X, unless such action is approved by the affirmative vote of the holders
of not less than 80% of the outstanding shares of the Corporation entitled to
vote on the matter.

          IN WITNESS WHEREOF, the undersigned, being the incorporator
hereinabove named for the purpose of forming a corporation to do business both
within and without the State of Delaware, do make and file this Certificate,
hereby declaring under penalties of perjury that it is my act and deed and that
the facts stated herein are true.

quorum except when a vacancy or vacancies prevents such majority, whereupon a
majority of the directors in office shall constitute a quorum, provided that
such majority shall constitute at least one-third of the whole Board.  Every act
or decision done or made by a majority of the directors present at a meeting
duly held at which a quorum is present shall be regarded as the act of the
Board, unless a greater number be required by law or by Certificate of
Incorporation.  A meeting at which a quorum is initially present may continue to

approved by at least a majority of the required quorum for such meeting.

Board, however called and noticed, and wherever held, are as valid as though a
meeting had been duly held after regular call and notice if a quorum be present
and if, either before or after the meeting, each of the directors not present

reimbursement for expenses, as may be fixed or determined by the Board.

          SECTION 14.  ACTION WITHOUT MEETING.  Any action required or permitted

minutes of the proceedings of the Board or committee.

          SECTION 15.  COMMITTEES.  The Board may appoint one (1) or more

on such matters and in such fashion as the Board may from time to time request.
Such advisory directors shall be entitled to notice of, and to attend, regular
and special meetings of the Board, but shall not be entitled to vote at such
meetings and may be appointed or removed at the pleasure of the Board.  Such

          SECTION 5.  DUTIES AND COMPENSATION.  Officers of the Corporation
                      -----------------------

the General Manager and Chief Executive Officer of the Corporation and shall,
subject to the power and authority of the Board of Directors, have general
supervision, direction, and control of the officers, employees, business, and
affairs of the Corporation.


                               ARTICLE V.  STOCK.

          SECTION 1.  FORM OF STOCK CERTIFICATE.  Every holder of stock in the
                      -------------------------

facsimile signature.  If any officer, transfer agent or registrar who has signed
or whose facsimile signature has been placed upon a certificate shall have
ceased to be such officer, transfer agent or registrar before such certificate

stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualification, limitations or
restrictions of such preference and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the Corporation shall
issue to represent such class or series of stock.  Except as otherwise provided
in Section 202 of the Delaware General Corporation Law, in lieu of the foregoing
requirements, there may be set forth on the face or back of the certificate a
statement that the Corporation will furnish without charge to each stockholder
who so requests the powers, designations, preferences and relative,

                      --------------------------------------                
direct a new certificate or certificates be issued in place of any certificate
theretofore issued alleged to have been lost, stolen or destroyed, upon the
making of an affidavit of the fact by the person claiming the certificate to be
lost, stolen or destroyed.  When authorizing such issue of a new certificate,
the Board may, in its discretion and as a condition precedent to the issuance,
require the owner of such certificate or certificates, or such person's legal
representative, to give the Corporation a bond in such sum as it may direct as
indemnity against any claim that may be made against the Corporation with
respect to the lost, stolen or destroyed certificate.

assignment or endorsements thereof executed or entered into between the

actual knowledge on the part of the other person that the signing officers had
no authority to execute the same.  Any such instruments may be signed by any
other person or persons and in such manner as from time to time shall be
determined by the Board, and, unless so authorized by the Board, no officer,
agent or employee shall have any power or authority to bind the Corporation by
any contract or engagement or to pledge its credit or to render it liable for
any purpose or amount.

          SECTION 2.  REPRESENTATION OF SHARES OF OTHER CORPORATIONS.  The

<PAGE>
 
          SECTION 3.  SEAL.  It shall not be necessary to the validity of any

instrument executed by any authorized officer or officers of the Corporation
that the execution of such instrument be evidenced by the corporate seal, and
all documents, instruments, contracts and writings of all kinds signed on behalf
of the Corporation by any authorized officer or officers shall be as effectual

the same had been evidenced by affixing the corporate seal thereto.  The Board
may give general authority to any officer to affix the seal of the Corporation
and to attest the affixing by signature.

          SECTION 4.  FISCAL YEAR.  The fiscal year of the Corporation shall be
                      -----------

Corporation, subject to the provisions of the Certificate of Incorporation, if
any, may be declared by the Board at any regular or special meeting, pursuant to
law, and may be paid in cash, in property or in shares of capital stock.

          Before payment of any dividend, there may be set aside out of any
funds of the Corporation available for dividends such sums as the directors from
time to time, in their absolute discretion, think proper as a reserve or
reserves to meet contingencies, or for equalizing dividends, or for repairing or
maintaining any property of the Corporation, or for such other purpose as the
directors shall determine to be in the best interest of the Corporation, and the
directors may modify or abolish any such reserve in the manner in which it was
created.


                         ARTICLE VII.  INDEMNIFICATION.

          SECTION 1.  RIGHT TO INDEMNIFICATION.  Each person who was or is a
                      ------------------------                              
party or is threatened to be made a party or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer
of the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged action
in an official capacity or in any other capacity while serving as a director,
officer, employee or agent, shall be indemnified and held harmless by the
Corporation to the fullest extent permitted by the laws of Delaware as the same
exist or may hereafter be amended (but in the case of such amendment, only to
the extent that such amendment permits the Corporation to provide broader
indemnification rights than said laws permitted the Corporation to provide prior
to such amendment) against all costs, charges, expenses, liabilities and losses
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid or to be paid in settlement and amounts expended in seeking
indemnification granted to such person under applicable law, this bylaw or any
agreement with the Corporation) reasonably incurred or suffered by such person
in connection therewith and such indemnification shall continue as to a person
who has ceased to be a director, officer, employee or agent and 

                                       13
<PAGE>
 
shall inure to the benefit of his or her heirs, executors and administrators;
provided, however, that except as provided in Section 2 of this Article VII, the
- --------  -------
Corporation shall indemnify any such person seeking indemnification in
connection with a proceeding (or part thereof) initiated by such person only if
such proceeding (or part thereof) was initiated or authorized by one or more
members of the Board. The right to indemnification conferred in this Section 1
shall be a contract right and shall include the right to be paid by the
Corporation the expenses incurred in defending any such proceeding in advance of
its final disposition; provided, however, that if the Delaware General
                       --------  -------
Corporation Law so requires, the payment of such expenses incurred by a director
or officer in his or her capacity as a director of officer (and not in any other
capacity in which service was or is rendered by such person while a director or
officer, including, without limitation, service to an employee benefit plan) in
advance of the final disposition of a proceeding shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such director
or officer, to repay all amounts so advanced if it shall ultimately be
determined that such director or officer is not entitled to be indemnified under
this Section 1 or otherwise. The Corporation may, by action of the Board,
provide indemnification to employees and agents of the Corporation with the same
scope and effect as the foregoing indemnification of directors and officers.

          SECTION 2.  RIGHT OF CLAIMANT TO BRING SUIT.  If a claim under Section
                      -------------------------------                           
1 of this Article VII is not paid in full by the Corporation within thirty (30)
days after a written claim has been received by the Corporation, the claimant
may at any time thereafter bring suit against the Corporation to recover the
unpaid amount of the claim and, if successful in whole or in part, the claimant
shall be entitled to be paid also the expense of prosecuting such claim.  It
shall be a defense to any such action (other than an action brought to enforce a
claim for expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any is required, has been
tendered to the Corporation) that the claimant has failed to meet a standard of
conduct which makes it permissible under Delaware law for the Corporation to
indemnify the claimant for the amount claimed.  Neither the failure of the
Corporation (including the Board, independent legal counsel or its stockholders)
to have made a determination prior to the commencement of such action that
indemnification of the claimant is permissible in the circumstances because he
or she has met such standard of conduct, nor an actual determination by the
Corporation (including the Board, independent legal counsel or its stockholders)
that the claimant has not met such standard of conduct, shall be a defense to
the action or create a presumption that the claimant has failed to meet such
standard of conduct.

          SECTION 3.  NON-EXCLUSIVITY OF RIGHTS.  The right to indemnification
                      -------------------------                               
and the payment of expenses incurred in defending a proceeding in advance of its
final disposition conferred in this Article VII shall not be exclusive of any
other right which any person may have or hereafter acquire under any statute,
provision of the Certificate of Incorporation, Bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.

          SECTION 4.  INSURANCE.  The Corporation may maintain insurance, at its
                      ---------                                                 
expense, to protect itself and any director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, 

                                       14
<PAGE>
 
liability or loss, whether or not the Corporation would have the power to
indemnify such person against such expense, liability or loss under Delaware
law.

          SECTION 5.  EXPENSES AS A WITNESS.  To the extent that any director,
                      ---------------------                                   
officer, employee or agent of the Corporation is by reason of such position, or
a position with another entity at the request of the Corporation, a witness in
any action, suit or proceeding, he or she shall be indemnified against all costs
and expenses actually and reasonably incurred by him or her or on his or her
behalf in connection therewith.

          SECTION 6.  INDEMNITY AGREEMENTS.  The Corporation may enter into
                      --------------------                                 
indemnity agreements with the persons who are members of the Board from time to
time, and with such officers, employees and agents as the Board may designate,
such indemnity agreements to provide in substance that the Corporation will
indemnify such persons to the full extent contemplated by this Article VII.

          SECTION 7.  EFFECT OF AMENDMENT.  Any amendment, repeal or
                      -------------------                           
modification of any provision of this Article VII by the stockholders and the
directors of the Corporation shall not adversely affect any right or protection
of a director or other of the Corporation existing at the time of the amendment,
repeal or modification.

Ladies and Gentlemen:

          At your request, we have examined the Registration Statement on Form
S-3 (File No. 333-_____) (the "Registration Statement") filed by you with the
Securities and Exchange Commission for purposes of registering under the
Securities Act of 1933, as amended, 629,754 shares (the "Company Shares") of
Class A Common Stock (including 180,000 shares which are subject to an over-
allotment option), $0.01 par value, and of 1,770,246 shares (the "Selling
Shareholders' Shares") of Class A Common Stock (including 180,000 shares which
are subject to an over-allotment option), $0.01 par value, which are presently
outstanding and held by certain of your existing shareholders.

          We have assumed the genuineness of all signatures (other than the
signatures of officers of the Company on the Registration Statement) the
authenticity of all documents submitted to us as originals and the conformity
with originals of all documents submitted to us as copies.

          On the basis of such examination, our reliance upon the assumptions
contained herein and our consideration of those questions of law we considered
relevant, and subject to the limitations and qualifications in this opinion, we
are of the opinion that the Company Shares and the Selling Shareholders' Shares
have been duly authorized by all necessary and corporate action on your part
and, upon payment for and delivery of the Company Shares and the Selling
Shareholders' Shares in accordance with the Registration Statement and the
countersigning of the certificate or certificates representing the Company
Shares and the Selling Shareholders' Shares by a duly authorized officer of the
registrar for the Company's Class A Common Stock, the Company Shares and the
Selling Shareholders' Shares will be validly issued, fully paid and non-
assessable.

          The law covered by this opinion is limited to the present federal law
of the United States and the present law of the State of California.  We express
no opinion regarding the statutes, administrative decisions, rules or
regulations of any county, municipality or special political subdivision or
other local authority.

          This opinion is furnished by us as counsel for you and may be relied
upon by you only in connection with the Registration Statement.  It may not be
used or relied upon by you for any other purpose or by any other person, nor may
copies by delivered to any other person, without in each instance our prior
written consent. You may, however, attach this opinion as an exhibit to the
Registration Statement.

                                    Respectfully submitted,



                                    O'Melveny & Myers LLP
