                                 _____________

                              GENERAL INFORMATION

          This Proxy Statement is furnished in connection with the solicitation
of proxies by the Board of Directors of Inference Corporation (the "Company" or
"Inference"), for use at the 1996 Annual Meeting of Shareholders to be held at
the Company's headquarters, located at 100 Rowland Way, Novato, California, on
Tuesday, July 2, 1996 at 1:00 p.m. local time, and any and all postponements or
adjournments thereof (the "Annual Meeting"). This Proxy Statement is being
mailed to the Company's shareholders on or about May 22, 1996.

MATTERS TO BE CONSIDERED AND RECORD DATE

          The 1996 Annual Meeting has been called (i) to elect directors to hold
office until their successors are elected and qualified; (ii) to ratify the
appointment of Ernst & Young LLP as the Company's independent public accountants
for the fiscal year ending January 31, 1997; (iii) to approve the adoption of
the 1996 Employee Stock Purchase Plan and the reservation of 500,000 shares of

reincorporation of the Company in the State of Delaware; and (vi) to transact
such other business as may properly come before the meeting or any postponement
or adjournment(s) thereof.

    
          On May 9, 1996, the record date fixed by the Board of Directors, the
Company had outstanding 7,990,008 shares of Common Stock.     
                          

QUORUM AND VOTING REQUIREMENTS

          The presence in person or by proxy of a majority of shares entitled to
vote at any meeting of shareholders will constitute a quorum for the transaction
of business. The shareholders are entitled to one vote per share on all matters
to be considered at the meeting. The Company's Restated Articles of
Incorporation provide that there is no cumulative voting in the election of
directors.

          Abstentions and broker non-votes are counted for purposes of
determining a quorum, but are not considered as having voted for purposes of
determining the outcome of a vote.

                            SOLICITATION OF PROXIES

          SHAREHOLDERS ARE URGED, WHETHER OR NOT THEY EXPECT TO ATTEND THE
ANNUAL MEETING, TO COMPLETE, SIGN, DATE, AND RETURN THE ACCOMPANYING PROXY IN
THE ENCLOSED ENVELOPE. Your executed Proxy may be revoked at any time before it
is exercised by filing with the Secretary of the Company at the Company's
principal executive offices a written notice of revocation or a duly executed
Proxy bearing a later date. The execution of the enclosed Proxy will not affect
your right to vote in person should you find it convenient to attend the meeting
and desire to vote. Your vote at the Annual Meeting will revoke your previously
executed Proxy; attendance at the Annual Meeting will not in and of itself
constitute the revocation of a Proxy.

          Votes cast at the Annual Meeting will be tabulated by representatives
of Harris Trust Company of California, the persons appointed by the Board of
Directors to act as inspectors of election for the Annual Meeting and any
postponement or adjournment of the Annual Meeting. The inspectors of election
will determine the number of shares outstanding, the shares represented at the
Annual Meeting, the existence of a quorum and the
<PAGE>
 
authenticity, validity and effect of proxies; receive votes or ballots; hear and
determine all challenges and questions in any way arising in connection with the
right to vote; determine when the polls will close; and determine the results of
the election.

          Unless otherwise directed in the accompanying Proxy, the proxy holders
will vote FOR the proposals listed below. As to any other matters that may
properly come before the Annual Meeting, the proxy holders will vote in
accordance with their best judgment, although the Company does not presently
know of any such other matters.

          Proxies for the Annual Meeting are being solicited by mail directly
and through brokerage and banking institutions. The Company will pay all
expenses in connection with the solicitation of proxies. In addition to the use
of mails, proxies may be solicited by directors, officers and regular employees
of the Company personally, without extra compensation, by telephone, telegraph,
telefax or similar means. The Company may reimburse brokers and other persons
holding stock in their names, or in the names of nominees, for their expenses in
sending proxy materials to principals and obtaining their proxies.

    
          Corporate Investor Communications, Inc. has been engaged to assist in
solicitation for which it will receive from the Company a fee of approximately
$3,500.    


                                  PROPOSAL 1

    
                             ELECTION OF DIRECTORS     

          The Company's Restated Articles of Incorporation provide that in the
event that the authorized number of directors shall be fixed with at least six
(6) directors, the Board of Directors shall be divided into two classes,
designated Class I and Class II, effective as of the first annual meeting
following the date that the Company becomes a listed corporation within the
meaning of Section 301.5 of the California General Corporation Law (the "Initial
Annual Meeting").  Each class shall consist of one-half of the directors and the
initial class designation of a particular director shall initially be determined
by the Board of Directors.  All of the directors shall have two-year terms,
provided that the initial term of office of the directors of Class I shall
expire at the annual meeting to be held during the fiscal year following the
Initial Annual Meeting, and the initial term of office of the directors of Class
II shall expire at the annual meeting to be held during the second fiscal year
following the Initial Annual Meeting.

          The Company's authorized number of directors has been fixed with six
(6) directors, and the Company now is a listed corporation within the meaning of
Section 301.5 of the California General Corporation Law.  The Company's Board of
Directors is divided into two classes at this Annual Meeting as provided above.
The initial term of the Class I directors shall expire at the 1997 annual
meeting, and the initial term of the Class II directors shall expire at the 1998
annual meeting.  All six nominees listed below are presently directors of the
Company.  In the event the nominees named below refuse or are unable to serve as
directors (which is not anticipated), the persons named as proxies reserve full
discretion to vote for any and all persons as may be nominated.  The Board of
Directors has designated Dean O. Allen, C. Scott Gibson and John Watkins to
serve as the directors of Class I, and Peter R. Tierney, Anthony Sun and Eric
Herr to serve as the directors of Class II.

          Nonetheless, if the shareholders of the Company approve the
reincorporation of the Company into Delaware at this Annual Meeting (see
Proposal 5 below) and the merger of the Company into Inference Delaware (as
defined under Proposal 5 below) becomes effective, the Board of Directors shall
be divided into three classes.  All of the directors shall have three-year
terms, provided that the initial term of office of the directors of Class I
shall expire at the 1997 annual meeting, and the initial term of office of the
directors of Class II shall expire at the 1998 annual meeting, and the initial
term of office of the directors of Class III shall expire at the 1999 annual
meeting.  If elected, Dean O. Allen and John Watkins would serve as the Class I
directors, C. Scott Gibson and Eric Herr would serve as the Class II directors
and Peter R. Tierney and Anthony Sun would serve as the Class III directors.

ADDITIONAL INFORMATION REGARDING THE BOARD OF DIRECTORS

          The Board of Directors has two standing committees: (i) the Audit
Committee; and (ii) the Compensation Committee. The Audit Committee meets with
the Company's independant auditors, makes recommendations to the Board of
Directors concerning the acceptance of the reports of such auditors and the
accounting policies and procedures of the Company, and reviews financial plans
and operating results of the Company. The Audit Committee is comprised of
Messrs. Herr, Allen and Sun. During fiscal year 1996, the Audit Committee held 2
meetings. The Compensation Committee meets with management and makes
recommendations to the Board of Directors concerning the annual compensation for
all executive officers and key employees of the Company. The Compensation
Committee is comprised of Messrs. Gibson and Watkins. During fiscal year 1996,
the Compensation Committee held 4 meetings. The Board of Directors does not have
a standing nominating committee.

          During the fiscal year ended January 31, 1996, the Board held 15
meetings. Each director attended at least 75% of the meetings of the Board and
its committees on which they served during their period of service.

DIRECTOR COMPENSATION

          Directors are reimbursed for out-of-pocket travel expenses associated
with their attendance at Board meetings.  Directors receive no cash compensation
for their services on the Board of Directors or any committee thereof.

          In September 1993, in connection with his appointment to the Board of
Directors, C. Scott Gibson was granted options to purchase 16,000 shares of

of Directors.

          before July 15, 1996. J.P. Morgan Investment Corporation ("Morgan")
          also beneficially owns 1,190,332 of the Company's Class B Common Stock
          ("Class B Common Stock") and 161,579 shares of the Class B Common
          Stock upon exercise of warrants with exercise prices of $5.00 or $5.25
          per share. Except as provided by law, the Class B Common Stock
          generally is non-voting. A holder of Class B Common Stock may convert
          its Class B Common Stock into the Company's Class A Common Stock only
          to the extent that, as a result, it would not hold more than 5% of the
          outstanding shares of the Class A Common Stock. Thus, taking into
          account the number of shares which currently can be converted into
          Class A Common Stock, Morgan would beneficially own 5% of the
          Company's Class A Common Stock.

(1)       All stock options were granted under the Company's Amended and
          Restated 1993 Stock Option Plan (the "Plan") or in stock option
          agreements with terms similar to the terms of the Plan. For a
          description of the Plan, see "Summary Description of the Plan" in
          Proposal 4. All stock options vest over a period of four years,
          commencing one year from the date of grant.

(2)       All stock options were granted with exercise prices equal to the fair
          market value of the Common Stock on the grant date or, in the case of
          performance-based options, on the date the performance goals were
          achieved.

(3)       These amounts are based on compounded annual rates of stock price
          appreciation of five and ten percent over the 10-year term of the
          options. Actual gains, if any, on stock option exercises are dependent
          on the future performance of the Common Stock, overall stock market
          conditions, as well as the optionholders' continued employment
          throughout the vesting period. The amounts reflected in this table may
          not necessarily be achieved or may be exceeded. The indicated amounts
          are net of the option exercise price but before taxes that may be
          payable upon exercise.

(4)       These performance-based options were granted on March 7, 1995, and the
          exercise prices of such options are equal to the fair market value of
          the Company's Common stock on the date the performance goal was
          achieved. On the date that these options were granted, the fair market
          value of the Common Stock was equal to $7.00 per share. This $7.00
          price was used to determine the compounded annual rates of stock price
          appreciation reflected in this table.

                              COMPENSATION REPORT

          The Compensation Committee of the Board of Directors (the "Committee")
is comprised of two independent outside directors. No member of the Committee is
a former or current officer or employee of the Company or any of its
subsidiaries. The Committee is responsible for setting and administering the
policies that govern compensation for executive officers and key employees. The
Committee evaluates the performance of management and determines compensation
policies and levels. Prior to the Company's initial public offering which closed
on July 6, 1995, the Committee only made recommendations regarding executive
officer compensation to the full Board of Directors. Consequently, this
Compensation Report with respect to the Company's fiscal year ended January 31,
1996 reflects to some extent the decisions of the full Board of Directors.

OVERVIEW AND PHILOSOPHY

          The Company believes that compensation should reflect the value
created for its shareholders, while supporting the business strategies and long-
range plans of the Company. Accordingly, the Company's executive compensation
program is based on guiding principles designed to align compensation with the
Company's business strategy and its overall financial performance. These
principles are:

   (i)   to attract and retain key executives critical to the long-term success
         of the Company who are of the highest caliber; and

   (ii)  to motivate executives to enhance long-term shareholder value by
         building appropriate ownership in the Company.

          The Committee's approach is based upon a belief that a substantial
portion of aggregate annual compensation for executive officers should be
contingent upon the Company's performance and an individual's contribution to
the Company's success. In addition, the Committee strives to align the interests
of the Company's executive officers with the long-term interests of stockholders
through stock option grants that can result in ownership of the Company's Common
Stock.


EXECUTIVE OFFICER COMPENSATION

          The Company's compensation program for executive officers is based on
the following guidelines:

          .    Establishment of salary levels and participation in generally
               available employee benefit programs based on competitive
               compensation package practices.

          .    Utilization of an annual performance-based, cash incentive plan.

          .    Inclusion of equity opportunities that create long-term
               incentives based upon increases in shareholder return.

          In fiscal 1996, the Committee approved and the Company made awards
pursuant to a cash incentive plan that provided for bonus awards to be made to
the executive officers subject to an aggregate budget for all awards under the
plan. The plan established a minimum level of operating income to be achieved by
the Company quarterly and/or annually before any payments would be made under
the plan.

          The Company's operating income exceeded the target established under
the plan. As a result, the bonus awards to executive officers under the plan
were distributed to the executive officers as permitted by the plan. The total
of all payments under the plan were within the budget approved previously by the
Committee.

          Based upon the guidelines set forth above, during fiscal 1996, the
Committee approved modest increases in each of the executive officers' base
salary levels for fiscal 1997.  The Company maintains a set of guidelines for
use in making recommendations to the Committee on individual grants of stock
options, including the size of such grants, to executive officers.  Options to
purchase the Common Stock of the Company were granted to the executive officers
by reference to the guidelines.  These guidelines are developed by reference to
information that the Committee believes fairly reflect the competitive
environment in which the Company operates and which are consistent with the
compensation principles set forth above.

CHIEF EXECUTIVE OFFICER COMPENSATION

          Mr. Tierney has been CEO of the Company since 1991. His base salary
prior to the beginning of fiscal 1996 was $256,520, increased to $262,500 during
fiscal 1996, and increased further to $265,000 for fiscal 1997. These small
increases in base salary reflect the Committee's above described compensation
approach that annual compensation should be based to some extent on an incentive
bonus tied to the Company's annual performance.

          Mr. Tierney received a cash bonus in the amount of $150,000 based upon
Mr. Tierney's performance as reflected by the Company's operating income
results. Competitive pay practice data evaluated by the Committee was derived
from information of other technology companies, as compiled by the Committee.
The Committee focused on technology companies with similar revenues and similar
valuations.

          During fiscal 1996, the Committee granted to Mr. Tierney options to
purchase 172,000 shares of common stock which vest over four years. The
Committee believes Mr. Tierney has managed the Company well, and has achieved
distinguished results, including in terms of revenue, gross margin, operating
income and net income growth.

          The foregoing report has been furnished by the Company's full Board of
Directors:

     1 For purposes of this presentation, the Company has assumed that its
       initial offering price per share of $11.00 would have been the closing
       sales price on June 29, 1995, the day prior to the commencement of
       trading. Trading in the Company's Common Stock commenced on June 30, 1995
       and the Company's fiscal year ended January 31, 1996.
 
     2 Assumes that $100 was invested on June 29, 1995 in the Company's Common
       Stock at the Company's initial offering price of $11.00 per share and at
       the closing price for each index on that date and that all dividends were
       reinvested. No cash dividends have been declared on the Company's Common
       Stock.
 
       SHAREHOLDER RETURNS OVER THE INDICATED PERIOD SHOULD NOT BE CONSIDERED
       INDICATIVE OF FUTURE SHAREHOLDER RETURNS.

                             CERTAIN TRANSACTIONS

SPIN-OFF TRANSACTION

          Until recently, 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 includes the
Inference legacy products: ART, ART-IM and ART*Enterprise 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.  As of May 1, 1995 (the "Spin-Off Date"), the Company
transferred certain assets and liabilities of the Tools Business to Brightware,
Inc., a wholly-owned subsidiary of the Company ("Brightware"), and distributed
all of the shares of Brightware to the Company's shareholders (the "Spin-Off').
In connection with the Spin-Off, the Company retained ownership of its two
international subsidiaries, Inference Ltd. and Inference GmbH.  In addition to
distributing the products of the CBR Business, Inference Ltd. continues to
distribute the products of the Tools Business in certain specified countries.

          Master Contribution and Spin-Off Agreement.  Effective as of the Spin-
Off Date, the Company and Brightware entered into the Master Contribution and
Spin-Off Agreement (the "Master Agreement") that provides for, among other
things, the principal corporate transactions that were required to effect the
Spin-Off and certain other agreements governing the relationship between the
Company and Brightware. Under the terms of the Master Agreement, effective as of
the Spin-Off Date, Inference contributed to Brightware all the business,
properties, assets, goodwill and rights (other than the Retained Assets
described below) of Inference related exclusively to the Tools Business,
together with certain additional properties, assets and rights (collectively,
the "Acquired Assets"). The Acquired Assets included (i) personal computers,
software licensing agreements and related support agreements; (ii) existing
contracts exclusively with customers of the Tools Business and certain contracts
with customers of both the CBR Business and the Tools Business; (iii) certain
vendor licenses and agreements; (iv) accounts receivable of the Tools Business;
(v) cash in the amount of $1,683,750; (vi) certain capitalized software
associated with the Tools Business; (vii) certain technology and intellectual
property; and (viii) the books of account, records and files related to the
Tools Business. Inference retained ownership of all the business, properties,
assets, goodwill and rights of Inference that are not Acquired Assets
(collectively, the "Retained Assets"), including certain contracts with
customers of both the CBR Business and the Tools Business.

          Under the terms of the Master Agreement, Brightware assumed, and will
perform when due and indemnity and hold Inference harmless from and against all
liabilities and obligations of Inference related exclusively to the Acquired
Assets (other than the Retained Liabilities described below) (collectively, the
"Assumed Liabilities").  Inference retained and is solely responsible for, and
will indemnity and bold Brightware harmless from and against, all liabilities
and obligations of the Company that relate to the Retained Assets, obligations
under the terms of Company stock options held by employees of the Tools
Business, the accounts payable of the Tools Business as of the Spin-Off Date and
certain obligations of the Company relating to certain equipment leases and
other agreements of the Company (collectively, the "Retained Liabilities").

          As of the Spin-Off Date, all 57 employees of the Tools Business became
employees of Brightware.  Active participation of Tools Business employees in
the Inference benefit plans and programs ceased as of the Spin-Off Date.  For a
period of 18 months after the Spin-Off Date, the Company and Brightware will not
hire any employee of the other party unless such employee has not been employed
by such party for a period of three months.

          Under the terms of the Master Agreement, employment or termination
with Brightware will be deemed employment or termination with Inference for
purposes of the vesting and termination provisions of the Inference stock
options held by Brightware employees. All unvested Inference stock options held
by Brightware employees continue to vest in accordance with the terms of the
related stock option agreements and all vested Inference stock options held by
Brightware employees remain exercisable in accordance with the terms thereof;
provided, however, that all incentive stock options held by Brightware employees
were converted into nonqualified stock options. The exercise price for the
Inference stock options remained the same as prior to the Spin-Off Date. The
Master Agreement also provides that, in the event of the sale of all or
substantially all of the outstanding shares or assets of Brightware, or certain
mergers, reorganizations or other business combinations involving Brightware,
vesting of Company options held by Brightware employees will accelerate by one
year and the remaining unvested options lapse.

          Pursuant to the Master Agreement, Brightware granted options to
purchase shares of Brightware Common Stock to each transferred employee and each
remaining employee of the Company holding Inference stock options as of the 
Spin-Off Date based upon the percentage of Inference's fully diluted equity
represented by the Inference stock options held by such employees. The exercise
price of the Brightware stock options is the fair market value of the Brightware
Common Stock as of the date of grant.

          For a period of three years, Inference shall have a right of first
refusal with respect to the sale of Brightware to certain companies.

          Administration and General Service Agreement.  As of the Spin-Off
Date, Inference and Brightware entered into an Administration and General
Service Agreement (the "Administrative Services Agreement") pursuant to which
Inference was obligated to provide to Brightware, until January 31, 1996
(subject to a 90 day extension at the option of Brightware), certain services
and support relating to the day-to-day operations of the Tools Business. Such
services and support included (i) corporate administrative services, (ii)
computer systems and network services, (iii) operations support services, (iv)
customer services, training and technical support and (v) maintenance services.
The Administrative Services Agreement also sets forth the terms pursuant to
which Inference made available to Brightware certain offices and office
equipment in order to conduct the Tools Business following consummation of the
Spin-Off. For such services, support and facilities, Brightware paid Inference a
management fee in the aggregate of $760,000.

          Technology Transfer and License Agreement.  Pursuant to a Technology
Transfer and License Agreement (the "License Agreement"), Brightware was
assigned the proprietary rights to certain technologies and other assets used in
the Tools Business, including certain (i) source codes and binary codes, (ii)
documentation and other marketing and support materials, (iii) trademarks and
copyrights, (iv) trade secrets, including customer data, and (v) other
technology and proprietary information.  A portion of the CBR technology (the
"ART CBR Kernel"), however, is required for certain applications in the Tools
Business.  Inference, therefore, granted Brightware an irrevocable, perpetual,
worldwide, royalty-free, non-exclusive license to (y) use, reproduce, prepare
derivative works based upon, make, have made, enhance and distribute copies
under and otherwise sublicense the source code and binary code of the ART CBR
Kernel pursuant to the terms of the License Agreement and (z) distribute copies
of, offer for sale, sell, transfer ownership of, rent, lease, lend, perform
publicly and publicly display products embodying such source code and binary
code; provided, however, Brightware does not publicly disclose the source code.
Inference and Brightware also agreed to grant nonassignable, nontransferable and
nonexclusive permanent cross licenses with respect to certain Brightware
products and Inference products for the other's internal business purposes.  For
a period of 36 months from the Spin-Off Date, Brightware agreed not to compete
with the Company by releasing application software products that (i) use the
source code or binary code of the ART CBR Kernel, (ii) are competitive with
Inference in the call center market and (iii) are not positioned in any of the
possible Brightware application areas.

          The License Agreement also provides that Brightware has a limited
right to use the trademark and trade name "Inference" to identify its lineage
from Inference. For example, Brightware may use the phrase "formerly a Division
of Inference Corporation" in connection with the Tools Business. In addition, to
the extent Inference has trademark rights to "CBR" and "Case-Based Reasoning,"
Inference granted Brightware a perpetual, irrevocable royalty-free, non-
exclusive license to use such trademarks.

          Distributorship Agreements.  As of the Spin-Off Date, individual
Distributorship and Licensing Agreements (collectively, the "Distributorship
Agreements") were entered into by and between (i) Inference and Brightware, with
Inference as the distributor, (ii) Inference and Brightware, with Brightware as
the distributor and (iii) Brightware and Inference Ltd., a wholly-owned
subsidiary of Inference registered under the laws of the United Kingdom ("IL"),
with IL as distributor.  Each Distributorship Agreement sets forth the terms and
conditions pursuant to which the distributor may distribute within certain
specified territories certain proprietary software and computer programs, and
the reference manuals therefor, of the other party to the Distributorship
Agreement, and the terms of the limited licenses granted with respect to such
products.  The initial term of each Distributorship Agreement expires on April
30, 1998, subject to extension.  The distributorship arrangements are
nonexclusive, except with respect to the Distributorship Agreement between
Brightware and IL, which is exclusive in certain territories.

LIMBEX TRANSACTION

          Pursuant to a license agreement dated as of May 9, 1995, the Company
granted a worldwide, perpetual irrevocable license (with the right of
sublicense) to Limbex Corporation ("Limbex") with respect to certain of the
Company's technology (the "Licensed Technology") unrelated to the Company's
current CBR business.  Limbex paid the Company $100,000 on the execution of the
agreement and is obligated to make five semi-annual installments of $100,000
over 2-1/2 years from the date of the agreement, the last four of which are
guaranteed by Quarterdeck Corporation, a shareholder of Limbex ("Quarterdeck").
Limbex shall also pay royalties to the Company as follows: 3% of the net
revenues received by Limbex up to $2 million in royalties paid; and thereafter
4% of the net revenues received by Limbex up to an additional $3 million in
royalties paid, after which Limbex will have a fully paid, royalty-free license
for the licensed technology.  For a period of 2 years and 6 months from the date
of the agreement, the Company has agreed not to license or disclose the source
code of the Licensed Technology to other parties using such technology in
products that would be competitive with Limbex.  In the event Inference
terminates the license agreement under certain circumstances, and subject to
other terms and conditions, Quarterdeck has the right to assume the rights and
obligations of Limbex under the agreement.
 
          In connection with the license agreement, the Company was issued
convertible Series B Preferred Stock of Limbex, and the Company currently has a
22% interest in the equity of Limbex.  The shares of Limbex stock held by
Inference are subject to the terms of a buy-sell agreement and a shareholder
voting agreement.  One of the two principal shareholders of Limbex is Alexander
D. Jacobson who was previously the Company's Chairman of the Board and who
remains a principal shareholder of the Company.  The other principal shareholder
of Limbex is Bradley Allen, who was the principal developer of the Licensed
Technology while he was employed by the Company.  Both Mr. Jacobson and Mr.
Allen are also executive offices of Limbex.  Mr. Tierney, the Company's Chief
Executive Officer, is a director of Limbex.

OTHER TRANSACTIONS

          A letter agreement regarding severance dated as of February 28, 1995
was entered into by and between the Company and Alexander D. Jacobson, the
previous Chairman of the Company's Board of Directors and a principal
shareholder of the Company. Pursuant to the letter agreement, Mr. Jacobson's
employment with the Company terminated as of the date thereof, and the Company
agreed to pay Mr. Jacobson 14 months of his then current base salary (payable in
28 semi-monthly installments) and to continue extending certain health and life
insurance and other benefits to Mr. Jacobson; provided, however, upon Mr.
Jacobson's accepting employment with Limbex, such severance payments and
benefits terminated. Mr. Jacobson's then unvested stock options as of February
28, 1995 were accelerated, and all of his stock options were extended until
February 28, 1996.

          Lockheed Corporation ("Lockheed") and the Company are parties to the
License Agreement dated as of December 1984, and the Company and Lockheed
Missiles and Space Company, Inc., an affiliate of Lockheed, are parties to the
Value Added Reseller Agreement dated November 16, 1994.  Dean O. Allen, a member
of the Company's Board of Directors, is an officer of Lockheed.  Lockheed is
also a principal shareholder of the Company.  The revenues received by the
Company from these agreements in fiscal 1994, 1995 and 1996 were $67,000,
$80,000 and 9,000, respectively.

          The Company believes that the terms of all transactions described
above between the Company and the principal shareholders, the officers and
directors of the Company, or any of their affiliates, are not less favorable to
the Company than terms that could have been obtained from unaffiliated third
parties.

                                  PROPOSAL 2

              RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

          The Board of Directors has appointed the firm of Ernst & Young LLP,
independent public accountants, to audit the financial statements of the Company
for the fiscal year ending January 31, 1997, and recommends that the
shareholders vote for ratification of this appointment.  In the event the
shareholders do not ratify such appointment, the Board of Directors will
reconsider its selection.  Ernst & Young LLP has audited the Company's financial
statements since January 31, 1986.  Representatives of Ernst & Young LLP are
expected to be present at the Annual Meeting with the opportunity to make a
statement and to respond to appropriate questions.

REQUIRED VOTE

          The ratification of the appointment of Ernst & Young LLP as the
Company's independent public accountants requires the affirmative vote of the
holders of a majority of the shares of the Company's Common Stock present at the
Annual Meeting in person or by proxy and entitled to vote.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF ERNST &
YOUNG LLP AS THE COMPANY'S INDEPENDENT PUBLIC ACCOUNTANTS FOR THE YEAR ENDING
JANUARY 31, 1997.



                                  PROPOSAL 3

                     APPROVAL OF ADOPTION OF THE INFERENCE
                   CORPORATION EMPLOYEE STOCK PURCHASE PLAN

          The Board of Directors has adopted, subject to shareholder approval,
the Inference Corporation Employee Stock Purchase Plan (the "Stock Purchase
Plan") effective as of August 1, 1996. Under the Stock Purchase Plan, 500,000
shares of the Company's Common Stock would be available for purchase by eligible
employees electing to participate in the Stock Purchase Plan. Such employees
would be entitled quarterly to purchase Common Stock of the Company, by means of
payroll deductions, at a 15% discount from the market price of the Company's
Common Stock. The Board of Directors believes that the Stock Purchase Plan would
provide an additional incentive to employees to achieve business goals of the
Company that would increase stock values and to remain in the employment of the
Company.

SUMMARY DESCRIPTION OF THE STOCK PURCHASE PLAN

          The material provisions of the Stock Purchase Plan are summarized
below. The following summary is qualified in its entirety by reference to the
text of the Stock Purchase Plan, a copy of which is set forth as Exhibit A to
this Proxy Statement.

          Operation of the Stock Purchase Plan. The Stock Purchase Plan operates
as follows. Prior to the first day of each quarter of each calendar year,
Qualified Employees (as such term is defined below) are given the opportunity to
participate in the Stock Purchase Plan. Participating Qualified Employees
("Participants") designate a certain amount of their after-tax base salary to be
set aside over the next three months (an "Offering Period") to purchase the
Company's Common Stock. On the last day of each Offering Period (each an
"Exercise Date"), the total amount set aside by each Participant is used to
purchase Common Stock. The purchase price of each share of Common Stock is 85%
of the closing price of a share of Common Stock on the NASDAQ National Market on
the first day of the Offering Period or the Exercise Date, whichever is lower.
Shortly after the Exercise Date, the Company issues to the Participants stock
certificates representing the shares purchased under the Stock Purchase Plan. If
the Stock Purchase Plan is approved by shareholders of the Company, the first
Offering Period shall be a short period of two months commencing on August 1,
1996 and ending on September 30, 1996.

                                       16
<PAGE>
 
          Eligibility.  Only Qualified Employees are eligible to participate in
the Stock Purchase Plan. The Stock Purchase Plan defines a "Qualified Employee"
as an employee of the Company or any of its subsidiaries who has completed 12
months of continuous service with the Company or such subsidiary as of the first
date of the applicable Offering Period and who is customarily employed for more
than 20 hours per week and more than five months in a calendar year. The term
"Qualified Employee" does not include any employee who, after giving effect to
his or her participation in the Stock Purchase Plan, owns or would own stock
representing 5% or more of the total combined voting power or value of all
classes of stock of the Company or any of its subsidiaries. As of April 15,
1996, there were approximately 113 Qualified Employees, and the executive
officers of the Company are Qualified Employees.

          Limitations on Amount of Shares to Purchase.  The fair market value of
stock purchased by any Participant cannot exceed $25,000 in any calendar year.
In addition, the maximum amount that a Participant may elect to set aside under
the Stock Purchase Plan in each Offering Period is 10% of his or her base
salary.  The minimum amount that a Participant may elect to set aside each pay
period is $10.00.

          Term of Stock Purchase Plan.  The Stock Purchase Plan has no definite
term and will terminate when all of the shares subject to the Stock Purchase
Plan have been purchased unless terminated sooner by the Board of Directors.

          Termination of Employment.  The Stock Purchase Plan does not restrict
the Company's right to terminate the employment of Participants. The Stock
Purchase Plan provides that upon termination of a Participant's employment due
to death, disability or retirement, the Participant or his or her personal
representative may elect to either (i) purchase Common Stock under the Stock
Purchase Plan as of the coinciding or next following Exercise Date using the
funds credited to the Participant's account as of the date of death, disability
or retirement, or (ii) receive a refund of the balance of the Participant's
account. Upon termination of employment for a reason other than death,
disability or retirement, the Participant will be deemed to have withdrawn from
the Stock Purchase Plan and all amounts credited to his or her account for that
Offering Period will be refunded to him or her without interest. Termination of
employment has no effect on shares previously purchased under the Stock Purchase
Plan.

          Acceleration Provision.  Upon the dissolution or liquidation of the
Company, or upon a reorganization of the Company with one or more corporations
as a result of which the Company is not the surviving corporation, or upon a
sale of all or substantially all of the property of the Company to another
corporation, the Stock Purchase Plan will terminate and the rights of
Participants to purchase shares under the Stock Purchase Plan will terminate and
the Company thereupon will refund the balance of a Participant's accounts to the
Participant, unless (i) the Committee (as such term is defined below) of the
Board of Directors determines that the rights of Participants to purchase shares
should accelerate or (ii) provision is made in connection with such transaction
for the assumption of the Stock Purchase Plan or the substitution of rights to
purchase the Company's Common Stock with rights to purchase stock of a successor
employer corporation or an affiliate thereof, with appropriate adjustments as to
number and kind of shares and prices.  If the Committee determines to accelerate
the rights of Participants to purchase Common Stock, the acceleration date
designated by the Committee will be deemed to be the Exercise Date for purposes
of computing the option price of the accelerated option.

          Amendment or Termination of the Stock Purchase Plan.  The Board of
Directors may amend, suspend or terminate the Stock Purchase Plan at any time
and from time to time; provided, however, that, if any amendment would (i)
materially increase the benefits accruing to Participants under the Stock
Purchase Plan, (ii) materially increase the aggregate number of shares of Common
Stock that may be issued under the Stock Purchase Plan, or (iii) materially
modify the requirements as to eligibility for participation in the Stock
Purchase Plan, then to the extent required by Rule 16b-3 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or required under Section
423 of the Internal Revenue Code of 1986, as amended (the "Code"), or any other
applicable law, or deemed necessary or desirable by the Board, such amendment
will be subject to stockholder approval.

          Administration.  The Board of Directors may appoint a Committee of the
Board of Directors to administer the Stock Purchase Plan.  The Committee would
be composed of not less than two directors of the Company, each of whom is a
"disinterested person" as that term is defined in Rule 16b-3(c)(2)(i) of the
Exchange Act.  The Committee would have the power to make, amend and repeal
rules and regulations for the interpretation and administration of the Stock
Purchase Plan that are consistent with applicable tax and securities laws.

                                       17

          Federal Income Tax Consequences.  The Stock Purchase Plan is intended
to qualify as an "employee stock purchase plan" under Section 423 of the Code.
Under the Code, no taxable income is recognized by a Participant either as of
the first day of each Offering Period ("Grant Date") or the last day of the
Offering Period (the "Exercise Date"). Depending upon the length of time the
acquired shares are held by the Participant, the federal income tax consequences
will vary. If the shares are held for a period of two years or more from the
Grant Date and for at least one year from the Exercise Date (the "Required
Period"), and are sold at the price in excess of the purchase price paid by the
Participant for the shares, the gain on the sale of the shares will be taxed as
ordinary income to the Participant to the extent of the lesser of (i) the amount
by which the fair market value of the shares on the Grant Date exceeded the
purchase price, or (ii) the amount by which the fair market value of the shares
at the time of their sale exceeded the price paid for the shares. Any portion of
such gain not taxed as ordinary income will be treated as long-term capital gain
to the Participant. If the shares are held for the Required Period and are
subsequently sold at a price less than the purchase price paid by the
Participant for the shares, the loss on the sale will be treated as long-term
capital loss to the Participant. If the shares are held for the Required Period
and are subsequently sold by the Participant, whether at a gain or loss, the
Company will not be entitled to any deduction for federal income tax purposes.

          If a Participant disposes of shares within the Required Period, the
Participant will recognize ordinary income in an amount equal to the difference
between the purchase price paid by the Participant for the shares and the fair
market value of the shares on the Exercise Date, and the Company will be
entitled to a corresponding deduction for federal income tax purposes.  In
addition, if a Participant disposes of shares within the Required Period at a
price in excess of the purchase price paid by the Participant for the shares,
the Participant will recognize a capital gain in an amount equal to the
difference between the selling price of the shares and the fair market value of
the shares on the Exercise Date.  Alternatively, if such shares are disposed of
during the Required Period at a price less than the fair market value of the
shares on the Exercise Date, the Participant will recognize a capital loss in an
amount equal to the difference between the fair market value of the shares on
the Exercise Date and the selling price of the shares.  The Company will not
receive a deduction for federal income tax purposes with respect to any capital
gain recognized by a Participant who sells shares within the Required Period.

          The foregoing tax summary is based upon federal income tax laws in
effect as of April 15, 1996.

          The benefits that would be received by or allocated to executive
officers of the Company participating in the Stock Purchase Plan and to other
Qualified Employees cannot be determined at this time because a Qualified
Employee's participation in the Stock Purchase Plan and the amount of funds set
aside to purchase shares under the Stock Purchase Plan (subject to the
limitations discussed above) are entirely within the discretion of the
Participant. The closing price of the Company's Common Stock on the NASDAQ
National Market on April 15, 1996, as reported in the Western Edition of The
Wall Street Journal, was $18.00 per share.

REQUIRED VOTE

               The affirmative vote of the holders of a majority of the shares
of the Company's Common Stock present at the Annual Meeting in person or by
proxy and entitled to vote is required to approve the adoption of the Inference
Corporation Employee Stock Purchase Plan and the reservation of 500,000 shares
of Common Stock thereunder.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE
INFERENCE CORPORATION EMPLOYEE STOCK PURCHASE PLAN AND THE RESERVATION OF
500,000 SHARES OF COMMON STOCK THEREUNDER.

                                  PROPOSAL 4

                        AMENDMENTS TO STOCK OPTION PLAN

          At the Annual Meeting, shareholders are being asked to approve
amendments to the Company's Amended and Restated 1993 Stock Option Plan (the
"Plan"). The Plan provides a means to attract and retain officers and key
employees and promote the success of the Company.

PROPOSED AMENDMENTS TO THE PLAN

          Number of Shares Issuable.  Subject to approval by a majority of the
          -------------------------                                           
shareholders, the Board of Directors has approved an amendment to the Plan to
increase the number of shares of Class A Common Stock of the Company ("Common
Stock") authorized to be issued under the Plan by 500,000 shares, from 800,000
shares to 1,300,000 shares.  At the Annual Meeting, shareholders will be
requested to approve this increase.

          At April 15, 1996, options covering 635,815 shares of Common Stock had
been granted under the Plan and of this amount options covering 53,793 shares
had been exercised, leaving 164,185 shares currently available to be granted.
This number of available shares is insufficient to fulfill the Company's
compensation objectives. Equity incentives have continually been a significant
component of compensation for the Company's employees. By linking key employees'
compensation to corporate performance, the employees' reward is directly related
to the Company's success. The Company believes the use of equity incentives
increases employee motivation to improve shareholder value.

          Acceleration of Vesting.  In addition, the Board of Directors approved
          -----------------------
the following provisions to be included in the Plan:

          (a)  The Board of Directors in its sole discretion can accelerate the
     time at which an option or an installment of an option may be exercised;
     and

          (b)  Upon the dissolution or liquidation of the Company, or upon a
     reorganization, merger or consolidation of the Company with one or more
     corporations as a result of which the Company goes out of existence or
     becomes a subsidiary of another corporation (other than any reorganization,
     merger or consolidation effected to change the Company's state of
     incorporation), or upon a sale of substantially all of the Company's
     property or a sale of more than eighty percent (80%) of the then
     outstanding stock of the Company to another corporation (collectively, a
     "Terminating Transaction"), all optionees shall have the right, at such
     time immediately prior to the consummation of the Terminating Transaction
     as the Board shall designate, to exercise their stock options to the full
     extent not previously exercised, including any unvested installments. Upon
     consummation of any Terminating Transaction, the Plan will terminate and
     any outstanding stock options will terminate unless provision is made in
     writing in connection with the Terminating Transaction for the continuance
     of the Plan and for the assumption of the stock options, or for the
     substitution for such stock options of new options covering the securities
     of a successor employer corporation, or an affiliate thereof, with
     appropriate adjustments as to the number and kind of securities and prices.

          Prior to these amendments, in the event of a Terminating Transaction
or otherwise, stock options granted under the Plan could not be accelerated.
However, the proposed acceleration provisions discussed above are contained in
the Company's Fourth Amended and Restated Inference Corporation Incentive Stock
Option Plan and Nonstatutory Stock Option Plan and in several stock option
agreements.

REQUIRED VOTE

          The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock present at the Annual Meeting in person or by proxy and
entitled to vote is required to approve the amendment to increase the number of
shares available for issuance under the Plan by 500,000 shares and to provide
for accelerated vesting of options in certain events or at the discretion of the
Board of Directors (collectively, the "Amendments").

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE
AMENDMENTS.

SUMMARY DESCRIPTION OF THE PLAN.

          The material features of the Plan are described below.

          Purpose of the Plan
          -------------------

          The Plan was adopted to promote the growth and profitability of the
Company by providing, through the granting of options, incentives to attract
highly talented persons to positions with the Company, to retain such persons
and to motivate them to use their best efforts on behalf of the Company. The
Plan is composed of two parts: the Incentive Stock Option Plan (the "Incentive
Plan") and the Nonstatutory Stock Option Plan (the "Nonstatutory Plan"). Options
granted under the Incentive Plan ("Incentive Options") are intended to qualify
as "incentive stock options" under the requirements of Section 422 of the
Internal Revenue Code of 1986, as amended ("Code"). Options granted under the
Nonstatutory Plan ("Nonstatutory Options") are not intended to qualify as
Incentive Options. Incentive Options and Nonstatutory Options granted or to be
granted under the Plans are collectively referred to herein as "Stock Options."

          Administration of the Plan
          --------------------------

          The Plan is administered by the Board of Directors of the Company (the
"Board").  Subject to the provisions of the Plan, the Board has sole discretion
to determine from among eligible persons to whom, and the time or times at
which, options may be granted, the number of shares of Common Stock to be
subject to each option, and the period for the exercise of each Stock Option.
Under the Plan, the Board has discretion, within the limits set by the Plan to
interpret the Plan, to prescribe, amend or rescind rules and regulations
relating to the Plan, to determine the details and provisions of each stock
option agreement between the Company and each person to whom options are
granted, to delegate some or all of its powers under the Plan to a committee of
the Board and to make all other determinations necessary or appropriate in the
administration of the Plan.

          Securities Subject to the Plan
          ------------------------------

          The maximum aggregate number of shares of Common Stock of the Company
which may currently be optioned and sold under the Plan is 800,000 shares. This
constitutes an absolute cumulative limitation on the total number of shares that
may be optioned under both the Incentive Plan and the Nonstatutory Plan;
therefore, at any particular date, the maximum aggregate number of shares which
may be optioned under the Plan is equal to 800,000 minus the number of shares
previously issued or subject to then outstanding options under the Plan. Shares
of Common Stock that are subject to Stock Options which for any reason terminate
or expire without being exercised shall again be available for granting under
the Plan.

          The number or kind of shares reserved for issuance under the Plan, as
well as the number of shares and the purchase prices covered by outstanding
Stock Options, are subject to proportionate adjustment by the Board to reflect
reorganizations, stock splits, stock dividends and other changes in the
capitalization of the Company.

          Employees, Directors and Consultants Who May Participate in the Plans
          ---------------------------------------------------------------------

          Any employee who contributes materially to the success of the Company
or any Parent or Subsidiary Corporation (as such terms are defined in the Stock
Option Plan, each a "Participating Company") is eligible to participate in the
Incentive Plan. Any employee, director (including non-employee directors) or
consultant who contributes materially to the success of any Participating
Company is eligible to participate in the Nonstatutory Plan. The Board of
Directors, in its sole discretion, has the power to determine which persons meet
the eligibility requirements of the Plan and which persons shall be granted
Stock Options.

          Terms and Conditions of Options
          -------------------------------

          Option Agreement.  Options granted under the Plan will be evidenced by
a stock option agreement in such form as the Board of Directors may from time to
time approve. Other than the stock option agreement, optionees are not provided
with any periodic or other report concerning the status of their individual
options. The Company will distribute to each optionee copies of all reports,
proxy statements and other communications which are distributed to its
shareholders generally. The Company will also supply information in response to
inquiries.

                                       20
<PAGE>
 
          Option Price.  The option exercise price for shares to be issued under
the Plan will be determined by the Board, but in no event may the option
exercise price be less than the fair market value of the Common Stock on the
date the option is granted. If the optionee holds more than 10% of the
outstanding shares of the Company's Common Stock, the option exercise price may
not be less than 110% of the fair market value of the Common Stock on the date
the option is granted.


          The term "fair market value" means:  (i) if shares are exchange-traded
or traded on the NASDAQ National Market, the closing sales price per share of
the shares; (ii) if shares are regularly traded in any over-the-counter market
other than the NASDAQ National Market, the average of the bid and asked prices
per share of the shares; and (iii) if shares are not traded as described in (i)
or (ii) above, the per share fair market value of the shares as determined in
good faith by the Board on such basis as the Board in its sole discretion shall
choose. The date of determination of fair market value with respect to (i) and
(ii) above shall be the date of the option grant, or if no trading in the shares
takes place on such date, on the next preceding trading day on which there has
been such trading. The date of determination of fair market value with respect
to (iii) above shall be the date of the option grant.

          Term and Exercisability of Options.  The term of Stock Options granted
under the Plan shall be for such periods as the Board determines and shall vest
and become exercisable in such installments and at such times as the Board may
provide in each individual Stock Option grant, but at a rate not less than
twenty percent (20%) per year, and the Board may thereafter in its sole
discretion accelerate the time at which an option or installment may be
exercised. The period for the exercise of each Stock Option cannot exceed ten
(10) years from the date of grant, except in the case of a shareholder holding
more than ten percent (10%) of the outstanding shares of the Company's Common
Stock, in which case the term for the exercise of an Incentive Option cannot
exceed five (5) years from the date of grant.

          Termination of Employment or Directorship.  In general, in the event
of termination of employment or a directorship by reason of an optionee's
disability or death, any unexercised vested installments of Stock Options
granted under the Plan of such optionee will expire and become unexercisable as
of the earlier of (a) the original termination date of the option, or (b) the
first anniversary of the date of such termination of employment or directorship.
In the event that an optionee's employment or directorship with the Company or a
Participating Company is terminated for any reason other than death or
disability, any unexercised vested installments of options granted under the
Plan to such an optionee shall expire and become unexercisable as of the earlier
of (i) the original termination date of the option or (ii) three (3) months
following the termination of employment or of directorship. Regardless of the
reason for the termination of the optionee's employment or directorship, the
Board in its discretion, with the consent of the optionee or the optionee's
estate (in the case of the death of the optionee), may extend the period of time
in which unexercised vested installments of Stock Options remain exercisable
after termination of the optionee's employment or directorship, but not later
than the original termination date of the option. In the case of Incentive
Options, such an extension may result in loss of the tax treatment accorded
Incentive Options. Any installments of a Stock Option that have not vested as of
the date of termination of employment or directorship for any reason will expire
and become unexercisable as of the date of such termination.

          Terminating Transactions.  Upon the dissolution or liquidation of the
Company, or upon a reorganization, merger or consolidation of the Company with
one or more corporations as a result of which the Company goes out of existence
or becomes a subsidiary of another corporation (other than any reorganization,
merger or consolidation effected to change the Company's state of
incorporation), or upon a sale of substantially all of the Company's property or
a sale of more than eighty percent (80%) of the then outstanding stock of the
Company to another corporation (collectively, a "Terminating Transaction"), all
optionees shall have the right, at such time immediately prior to the
consummation of the Terminating Transaction as the Board shall designate, to
exercise their Stock Options to the full extent not previously exercised,
including any unvested installments (in such case certain of the Incentive
Options could lose the tax treatment accorded to Incentive Options). Upon
consummation of any Terminating Transaction, the Plan will terminate and any
outstanding Stock Options will terminate unless provision is made in writing in
connection with the Terminating Transaction for the continuance of the Plan and
for the assumption of the Stock Options, or for the substitution for such Stock
Options of new options covering the securities of a successor employer
corporation, or an affiliate thereof, with appropriate adjustments as to the
number and kind of securities and prices.

          Limitations on Transfer
          -----------------------

          No Stock Option granted under the Plan may be transferred by an
optionee other than by will or the laws of descent and distribution and, during
the lifetime of an optionee, the option will be exercisable only by the
optionee.

          Exercise of Options
          -------------------

          Stock Options may be exercised in full or in part (except with respect
to fractions of shares) and are deemed to be exercised upon receipt by the
Company of written notice of such exercise and full payment for the shares
covered by the exercise. The exercise price is payable by cash upon exercise of
the Stock Option. An optionee may also exercise shares of Common Stock using
previously acquired Common Stock, subject to all restrictions and limitations of
applicable law and the terms of the Plan.

          Amendment or Termination
          ------------------------

          The Plan provides that the Board may at any time amend, alter, and/or
terminate the Plan; provided, however, the Board shall not amend the Plan in any
manner which would adversely affect Stock Options previously granted.  To the
extent necessary or desirable to comply with Rule 16b-3 of the Exchange Act, the
Code or any other applicable law or regulation, the Company shall obtain
shareholders' approval of any amendment to the Plan in such a manner and to such
a degree as required.

          Unless sooner terminated by the Board, the Plan will terminate on
September 15, 2003, and no further options may be granted thereafter.
Termination of the Plan will not affect any right to purchase shares granted
under the Plan prior to the date of termination.

FEDERAL INCOME TAX CONSEQUENCES

          Nonstatutory Options
          --------------------

          The grant of a Nonstatutory Option under the Nonstatutory Plan will
not result in taxable income to the recipient at the time of the grant. When the
holder exercises the Nonstatutory Option, however, he or she will generally
recognize ordinary income equal to the difference between the option price and
the fair market value of the shares at the time of exercise. If the option
holder exercises the option within six months of its date of grant and is
subject to the restrictions on resale of Common Stock under Section 16(b) of the
Exchange Act, such person instead generally recognizes ordinary income at the
end of the six-month period following the date the option was granted.
Nevertheless, such a participant may elect within 30 days after the date of
exercise to recognize ordinary income as of the date of exercise. The
Corporation is generally entitled to a corresponding deduction at the same time
and in the same amounts as the income recognized by the option holder.

          If a holder of a Nonstatutory Option pays the option exercise price
solely in cash, his or her basis in the shares acquired is equal to the fair
market value of the Common Stock on the date ordinary income is recognized and,
upon subsequent disposition, any further gain or loss is taxable either as a
short-term or long-term capital gain or loss, depending on how long the shares
of Common Stock are held. The holding period for such shares commences as of the
date ordinary income is recognized.

          If a holder of a Nonstatutory Option pays the exercise price, in full
or in part, with previously acquired shares of Common Stock, he or she will
recognize ordinary income in an amount equal to the excess of the fair market
value of the Common Stock received over the exercise price. No additional gain
or loss is recognized as a result of the disposition of previously acquired
shares of Common Stock. The shares of Common Stock received by the option
holder, equal in number to the previously acquired shares exchanged therefor,
will have the same basis and holding period as such previously acquired shares.
The shares of Common Stock received by the option holder in excess of the number
of previously acquired shares will have a basis equal to the fair market value
of such additional shares as of the date ordinary income is recognized. The
holding period for such additional shares will commence as of the date ordinary
income is recognized.

                                       22
<PAGE>
 
          Incentive Options
          -----------------

          An employee who is granted an Incentive Option under the Incentive
Plan does not recognize taxable income either on the date of grant or on the
date of its timely exercise, provided that, in general, the exercise occurs
during employment or within three months after termination of employment. Upon
disposition of the Common Stock acquired upon exercise of an Incentive Option,
long-term capital gain or loss will be recognized in an amount equal to the
difference between the sales price and the option exercise price, provided that
the employee has not disposed of the Common Stock within two years of the date
of grant or within one year from the date of exercise. If the employee disposes
of the Common Stock without satisfying both holding period requirements (a
"Disqualifying Disposition"), he or she will generally recognize ordinary income
at the time of such Disqualifying Disposition in an amount equal to the excess
of the fair market value of the Common Stock on the date of exercise (the value
on a later day may govern in the case of an optionee who exercises an Incentive
Option within six months of the date of grant and whose sale of Common Stock at
a profit could subject him or her to suit under Section 16(b) of the Exchange
Act) over the exercise price or, if less, the excess of the amount realized on
the Disqualifying Disposition over the exercise price. Any remaining gain or net
loss is treated as a short-term or long-term capital gain or loss, depending
upon how long the Common Stock is held. Unlike the case in which a Nonstatutory
Option is exercised, the Corporation is not entitled to a tax deduction upon
either the timely exercise of an Incentive Option or upon disposition of the
Common Stock acquired pursuant to such exercise, except to the extent that the
employee recognizes ordinary income in a Disqualifying Disposition.

          In addition to the regular income tax, an employee may be subject to
the federal alternative minimum tax if his or her alternative minimum taxable
income ("AMTI") exceeds certain amounts. The excess of the fair market value of
the Common Stock received upon exercise of an Incentive Option over the option
exercise price (the "spread") is includable in the employee's AMTI. In the case
of an optionee who exercises an Incentive Option within six months after its
date of grant and whose sale of Common Stock could subject him or her to suit
under Section 16(b) of the Exchange Act, it is generally the excess of the fair
market value on the date six months following the date of the grant of the
Incentive Option over the exercise price that is includable in AMTI. If a
Disqualifying Disposition occurs at a loss in the same taxable year that the
excess was includable in AMTI, the includable amount is limited to the excess of
the amount realized on the Disqualifying Disposition over the exercise price.
For the purpose of AMTI, the gain or loss on sale of the Common Stock is
calculated by including a basis adjustment for the amount included in AMTI upon
exercise.

          If the holder of an Incentive Option pays the exercise price, in full
or in part, with previously acquired shares of Common Stock, the exchange should
not affect the Incentive Option tax treatment of the exercise. Upon such
exchange, and except as otherwise described herein, no gain or loss should be
recognized on the exchange, and the shares of Common Stock received by the
participant which are equal in number to the previously acquired shares
exchanged therefor will have the same basis and holding period for long-term
capital gain purposes as the previously acquired shares. The option holder,
however, will not be able to utilize the old holding period for the purpose of
satisfying the Incentive Option statutory holding period requirements. Shares of
common stock received by the option holder in excess of the number of previously
acquired shares will have a basis of zero and a holding period which commences
as of the date the shares of common stock are issued to the option holder upon
exercise of the Incentive Option. If such an exercise is effected using Common
Stock previously acquired through the exercise of an Incentive Option, the
exchange of previously acquired shares of Common Stock will be considered a
disposition of such shares for the purpose of determining whether a
Disqualifying Disposition has occurred.

          Limitations on Deductibility
          ----------------------------

          If, as a result of certain changes in control of the Company, a
recipient's options become immediately exercisable, the additional economic
value, if any, attributable to the acceleration may be deemed a "parachute
payment." This amount will generally be deemed a parachute payment if such
value, when combined with the value of other payments which are deemed to result
from the change in control, equals or exceeds a threshold amount equal to 300%
of the recipient's average annual taxable compensation over the five calendar
years preceding the year in which the change in control occurs. In such case,
the excess of the total parachute payments over such recipient's average annual
taxable compensation will be subject to a 20% nondeductible excise tax in
addition to any income tax payable. The Company will not be entitled to a
deduction for that portion of any parachute payment which is subject to the
excise tax.

                                       23
<PAGE>
 
          Effective January 1, 1994, the amount which may be deducted by the
Corporation with respect to compensation paid to the Chief Executive Officer and
four other most highly compensated executives is generally limited to $1 million
per tax year for each individual. Options granted under the Plans may be exempt
from the $1 million limit because of a "performance-based" exception.

          Withholding Taxes
          -----------------

          In general, federal income taxes will be required to be withheld upon
the exercise of a Nonstatutory Option. (No withholding is currently required
upon exercise of an Incentive Option.) The tax consequences to a recipient of a
Nonstatutory Option under the Nonstatutory Plan will differ depending on the
manner in which the recipient elects to satisfy the withholding obligation.

          If the recipient delivers previously owned shares of Common Stock to
pay withholding taxes, the delivery of shares will be treated as a sale of stock
and the participant will recognize long-term or short-term capital gain or loss
depending upon the fair market value, basis and holding period of the previously
owned shares so used.

          If the recipient elects to have the Company reduce the number of
shares of Common Stock otherwise issuable, or a recipient tenders back shares
that were issued as part of a Nonstatutory Option, the recipient should
generally recognize no gain or loss as a result of the reduction in the net
number of shares received. However, if a recipient uses previously owned shares
of Common Stock to pay the exercise price of a Nonstatutory Option and the tax
withholding requirements are satisfied by the withholding of shares otherwise
issuable, the recipient's award will consist of two sets of shares. A number of
shares awarded, equal to the number of previously owned shares exchanged to
exercise the option, will have the same basis and holding period as the
previously owned shares. Shares awarded in excess of this number will have a
basis equal to their fair market value at the time of taxation and a holding
period beginning on the same date. If such excess shares have sufficient fair
market value to satisfy the withholding obligation, the recipient will recognize
no gain or loss as a result of the reduction in the number of shares of Common
Stock received. However, to the extent that any shares of Common Stock retained
by the Company to pay any withholding taxes have the same basis and holding
period as previously owned shares, the participant will recognize gain or loss
as described in the manner described above for tendering previously owned shares
to satisfy the tax withholding obligation.


REQUIRED VOTE

          The affirmative of the holders of a majority of the shares of the
Company's Common Stock present at the Annual Meeting in person or by proxy and
entitled to vote is required to approve the adoption of the Amendments.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE AMENDMENTS.

                                  PROPOSAL 5

                   REINCORPORATION IN THE STATE OF DELAWARE

          At the Annual Meeting, shareholders are being asked to approve the
reincorporation of the Company in the State of Delaware.

                              THE REINCORPORATION

GENERAL

          The following discussion summarizes certain aspects of the
reincorporation of the Company in the State of Delaware (the "Reincorporation")
pursuant to the merger of the Company into INFR, Inc., a Delaware company
("Delaware Inference"). This summary does not purport to be complete and is
qualified in its entirety by reference to the Merger Agreement, a copy of the
form of which is attached hereto as Exhibit B and is incorporated herein by
reference, and to the Certificate of Incorporation of Inference Delaware (the
"Inference Delaware Certificate of Incorporation"), a copy of which is attached
hereto as Exhibit C and is incorporated herein by reference. For purposes of
convenience in this discussion, Inference may sometimes hereinafter be referred
to as "Inference California." Copies of the Restated Articles of Incorporation
(the "Inference California Articles of Incorporation") and the Restated Bylaws
of Inference California (the "Inference California Bylaws") and the Bylaws of
Inference Delaware (the "Inference Delaware Bylaws") are available for
inspection at the principal office of Inference and copies will be sent to
shareholders of Inference on request.

          For the reasons set forth in this Proxy Statement, the Inference Board
of Directors believes that the best interests of Inference and its shareholders
will be served by the Reincorporation.  Inference shareholders are urged to read
carefully this section of the Proxy Statement, including the related exhibits,
before voting on the Reincorporation.

          Inference Delaware is a wholly-owned subsidiary of Inference formed
for the sole purpose of effecting the Reincorporation.  Pursuant to the Merger
Agreement, Inference California will be merged with and into Inference Delaware
(the "Reincorporation Merger").  Upon effectiveness of the Reincorporation
Merger, Inference California will cease to exist and Inference Delaware will
continue to operate the business of Inference under the name "Inference
Corporation."

          At the effective time of the Reincorporation Merger, the affairs of
Inference will be governed by the Inference Delaware Certificate of
Incorporation, the Inference Delaware Bylaws and the Delaware General
Corporation Law (the "Delaware GCL"), which differ in certain important respects
from the Inference California Articles of Incorporation, the Inference
California Bylaws and the California General Corporation Law ("GCL").  See "--
Certain Significant Differences Between the Inference California Articles of
Incorporation and the Inference Delaware Certificate of Incorporation" and "--
Significant Differences Between the Corporation Laws of California and
Delaware."

          Pursuant to the Merger Agreement, each outstanding share of Inference
Common Stock will automatically be converted into one share of Inference
Delaware Common Stock.  Each outstanding certificate representing a share or
shares of Inference Common Stock will continue to represent the same number of
shares of Inference Delaware Common Stock. IT WILL NOT BE NECESSARY FOR
INFERENCE SHAREHOLDERS TO EXCHANGE THEIR EXISTING STOCK CERTIFICATES FOR STOCK
CERTIFICATES OF INFERENCE DELAWARE.  The Common Stock of Inference California is
listed for trading on the NASDAQ National Market and it is anticipated that,
after the Reincorporation Merger, Inference Delaware's Common Stock will
continue to be traded on the NASDAQ National Market, without interruption, under
the same symbol ("INFR") used by Inference California prior to the
Reincorporation Merger, and that the NASDAQ National Market will consider the
delivery of existing stock certificates of Inference California as constituting
"good delivery" of shares of Inference Delaware in transactions subsequent to
the Reincorporation Merger.

          APPROVAL BY INFERENCE SHAREHOLDERS OF THE REINCORPORATION WILL
CONSTITUTE APPROVAL OF THE MERGER AGREEMENT, THE INFERENCE DELAWARE CERTIFICATE
OF INCORPORATION, AND ALL PROVISIONS THEREOF.

                                       25
<PAGE>
 
VOTE REQUIRED; DISSENTERS' RIGHTS

          Approval of the Reincorporation, which will also constitute approval
of the Merger Agreement, the Inference Delaware Certificate of Incorporation and
all provisions thereof, will require the affirmative vote of a majority of the
outstanding shares of Inference California entitled to vote.

          THE INFERENCE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE
REINCORPORATION AND RECOMMENDS THAT INFERENCE SHAREHOLDERS VOTE "FOR" THE
REINCORPORATION.

          Shareholders of Inference California will have no dissenters' rights
of appraisal with respect to the Reincorporation.  See "-- Significant
Differences Between the Corporation Laws of California and Delaware --
Dissenters' or Appraisal Rights."

PRINCIPAL REASONS FOR THE REINCORPORATION

          For many years Delaware has followed a policy of encouraging
incorporation in that state and, in furtherance of that policy, has been a
leader in adopting, construing and implementing comprehensive, flexible
corporation laws responsive to the legal and business needs of corporations
organized thereunder.  Many corporations have initially chosen Delaware for
their state of incorporation or have subsequently changed their corporate
domicile to Delaware in a manner similar to that proposed by Inference.  Because
of Delaware's prominence as the state of incorporation for many major
corporations, both the legislature and courts in Delaware have demonstrated an
ability and a willingness to act quickly and effectively to meet changing
business needs.  The Delaware courts have developed considerable expertise in
dealing with corporate issues, and a substantial body of case law has developed
construing Delaware corporate law and establishing public policies with respect
to corporate legal affairs.

          It is anticipated that Delaware corporate law will continue to be
interpreted and explained in a number of significant court decisions which may
provide greater predictability with respect to Inference's corporate legal
affairs.  The Inference Board of Directors believes that the Reincorporation
will also allow Inference to take advantage of the increased flexibility and
certain other features afforded by the Delaware GCL, some of which are not
permitted under the GCL.

ANTITAKEOVER IMPLICATIONS

          Delaware, like many other states, permits a corporation to adopt a
number of measures, through amendment of the corporate charter or bylaws or
otherwise, which are designed to reduce a corporation's vulnerability to
unsolicited takeover attempts.  The Reincorporation is not being proposed in
order to prevent such a change in control, nor is it in response to any present
attempt known to the Inference Board of Directors to acquire control of
Inference, obtain representation on the Inference Board of Directors or take
significant action which affects Inference.

          In the discharge of its fiduciary obligations to its shareholders, the
Inference Board of Directors continues to evaluate Inference's vulnerability to
potential unsolicited bidders.  In the course of its ongoing evaluation, the
Inference Board of Directors has considered or may consider in the future
certain additional defensive strategies designed to enhance the Inference Board
of Directors' ability to negotiate with an unsolicited bidder.  These strategies
include, but are not limited to, the designation and insurance of preferred
stock, the rights and preferences of which are determined by the Inference Board
of Directors.  Some of these measures may be implemented under the GCL.  There
is nonetheless substantial judicial precedent in the Delaware courts as to the
legal principles applicable to such defensive measures and as to the conduct of
a board of directors under the business judgment rule with respect to
unsolicited takeover attempts.

                                       26
<PAGE>
 
          Certain effects of the Reincorporation may be considered to have
antitakeover implications.  For example, Section 203 of the Delaware GCL
restricts certain "business combinations" with "interested stockholders" for
three years following the date that a person becomes an interested stockholder
unless the board of directors approves the business combination.  In addition,
certain changes to the relative rights of stockholders and management which have
antitakeover implications have been implemented pursuant to the Delaware GCL.
These changes, including the elimination of the right of stockholders
controlling at least ten percent (10%) of the voting shares to call a special
meeting of stockholders and the elimination of the right of stockholders to
remove a director other than for cause, will be implemented as part of the
Reincorporation.  For a detailed discussion of all of the changes which will be
implemented as part of the Reincorporation, see"-- Certain Significant
Differences Between the Inference California Articles of Incorporation and the
Inference Delaware Certificate of Incorporation."  For a discussion of these and
other differences between the corporation laws of California and Delaware, see
"-- Significant Differences Between the Corporation Laws of California and
Delaware."

POSSIBLE DISADVANTAGES OF REINCORPORATION

          Notwithstanding the unanimous belief of the Inference Board of
Directors as to the benefits to Inference and its shareholders of the
Reincorporation, some shareholders may find the Reincorporation to be
disadvantageous to the extent that it has the effect of discouraging a future
takeover attempt which is not approved by the Board of Directors of Inference
Delaware, but which the majority of the shareholders may deem to be in their
best interests or in which shareholders may receive a substantial premium for
their shares over the then current market value or over their cost basis in such
shares.  As a result of such effects of the Reincorporation, stockholders who
might wish to participate in a tender offer may not have an opportunity to do
so.

          In addition, to the extent that antitakeover provisions enable the
Inference Delaware Board of Directors to resist a takeover or a change in
control of Inference Delaware, they could make it more difficult to change the
existing Inference Delaware Board of Directors and management.  The provisions
of the Inference Delaware Certificate of Incorporation and the Inference
Delaware Bylaws could make a proxy contest a less effective means of removing or
replacing existing directors or could make it more difficult to make a change in
control of Inference Delaware which is opposed by the Board of Directors of
Inference Delaware.

          It should also be noted that the Delaware GCL has been criticized by
some commentators on the grounds that it does not afford minority stockholders
the same substantive rights and protections as are available in a number of
other states.  As will be noted in this Proxy Statement, significant changes
will occur in the rights of stockholders and the powers of management following
the Reincorporation.  These changes are discussed above or are reviewed below in
"Certain Significant Differences Between the Inference California Articles of
Incorporation and the Inference Delaware Certificate of Incorporation" and
"Certain Significant Differences Between the Corporation Laws of California and
Delaware."

POST-REINCORPORATION OPERATIONS

          The Reincorporation will change the legal domicile of Inference and
result in certain other changes of a legal nature, but will not result in any
change in the name, principal executive office, business management, assets or
liabilities of Inference.  Pursuant to the Merger Agreement, each option to
purchase shares of Inference Common Stock granted under the Amended and Restated
1993 Stock Option Plan, the Fourth Amended and Restated Incentive Stock Option
Plan and Nonstatutory Stock Option Plan or existing stock option agreements
(collectively, the "Option Plans") of Inference California which is outstanding
immediately prior to the effective time of the Reincorporation Merger will
become an option to purchase shares of Inference Delaware Common Stock on the
same terms and conditions granted as existed immediately prior to the effective
time of the Reincorporation Merger, and future options under the Option Plans
will be for shares of Inference Delaware Common Stock.  Other employee benefit
arrangements of Inference California will also be continued by Inference
Delaware upon the terms and subject to the conditions currently in effect.
Inference shareholders should note that approval of the Reincorporation will
also constitute approval of the assumption of the Option Plans.

                                       27
<PAGE>
 
          Upon effectiveness of the Reincorporation Merger, the daily business
operations of Inference will continue as at present.  The consolidated financial
condition and results of operations of Inference Delaware immediately after
consummation of the Reincorporation will be substantially identical to those of
Inference California immediately prior to the Reincorporation.  In addition,
upon effectiveness of the Reincorporation Merger, the Board of Directors of
Inference Delaware will consist of the Board of Directors of Inference
California immediately prior to the Reincorporation Merger.  The individuals
serving as executive officers of Inference California immediately prior to the
Reincorporation Merger will serve as executive officers of Inference Delaware
upon the effectiveness of the Reincorporation Merger.

          The Reincorporation shall take effect on the later of the date upon
which an appropriate filing is made with the Secretary of State of the State of
Delaware and the date upon which an appropriate filing is made with the
Secretary of State of the State of California, which filings will be made as
soon as practicable following shareholder approval of the Reincorporation and,
if the Merger is approved, the Effective Time, subject to the terms and
conditions of the Merger Agreement.

          The Merger Agreement provides that the Inference Board of Directors
may abandon the Reincorporation Merger at any time before the effectiveness of
the Reincorporation Merger if the Inference Board of Directors determines that
it is inadvisable for any reason.  In addition, the Merger Agreement may be
amended prior to the effective date of the Reincorporation Merger and either
before or after shareholder approval thereof, subject to applicable law.
However, no such amendment may be made which affects the rights of the Inference
shareholders in a manner which is materially adverse to them unless the
amendment has been adopted and approved by the Inference shareholders.

CERTAIN SIGNIFICANT DIFFERENCES BETWEEN THE INFERENCE CALIFORNIA ARTICLES OF
INCORPORATION AND THE INFERENCE DELAWARE CERTIFICATE OF INCORPORATION

          The provisions of the Inference Delaware Certificate of Incorporation
differ from those of the Inference California Articles of Incorporation in the
principal respects discussed below, including the implementation of certain
provisions in the Inference Delaware Certificate of Incorporation which alter
the rights of stockholders and the powers of management and which reduce
stockholder participation in important corporate decisions.  These provisions
have antitakeover implications and are described in detail below.  Approval by
shareholders of the Reincorporation will constitute an approval of the inclusion
in the Inference Delaware Certificate of Incorporation of each of the provisions
described below.  In addition, certain other changes altering the rights of
stockholders and powers of management could be implemented in the future (i) by
amendment of the Inference Delaware Certificate of Incorporation by the
Inference Delaware Board of Directors with stockholder approval, (ii) by
amendment of the Inference Delaware Bylaws by the Inference Delaware Board of
Directors without stockholder approval or (iii) by amendment of the Inference
Delaware Bylaws by the stockholders.  For a discussion of such changes, see "--
Significant Differences Between the Corporation Laws of California and
Delaware."  The following discussion is qualified in its entirety by reference
to Exhibit B hereto.

          Authorized Stock.  The Inference Delaware Certificate of Incorporation
authorizes the Board of Directors to fix the rights, preferences, privileges and
restrictions of one or more series out of the authorized shares of Preferred
Stock, including dividend rights, conversion rights, voting rights, terms of
redemption and liquidation preferences, without further vote or action by the
Inference Delaware stockholders.  Although the Inference Delaware Board of
Directors has no present intention of doing so, issuance of the authorized
Preferred Stock with terms giving it substantial voting power, conversion or
other rights could have the effect of (i) delaying, deferring or preventing a
change in control of Inference Delaware or (ii) otherwise affecting the rights
of holders of Inference Delaware Common Stock.

          Elimination of Shareholder Actions by Written Consent; Special
Meetings.  Both the Inference California Articles of Incorporation and the
Inference Delaware Certificate of Incorporation provide that any action required
or permitted to be taken by stockholders must be taken at a duly called and
noticed meeting of stockholders and may not be taken by written consent.

          The Inference California Bylaws permit a special meeting of
shareholders to be called by the Board of Directors, the Chairman of the Board,
the President or the holders of shares entitled to cast not less than ten
percent of the votes at such meeting.  Under the Delaware GCL, special meetings
may be called by the board of directors and such other persons as may be
authorized by the certificate of incorporation or the bylaws.  The Inference
Delaware Certificate of Incorporation and the Inference Delaware Bylaws contain
no provision for special meetings of stockholders to be called by stockholders
of Inference Delaware.  Consequently, stockholders of Inference Delaware will
not be able to call special meetings of stockholders.

                                       28

          The provisions prohibiting stockholder action by written consent would
prevent the holders of a majority of the voting power of Inference Delaware from
using the written consent procedure to take stockholder action.  Persons
attempting unfriendly takeovers of corporations have attempted to use written
consent procedures in order to deal directly with stockholders and avoid
negotiations with the boards of directors of such companies.  The provisions
regarding the elimination of the right of stockholders to call a special meeting
would mean that a stockholder could not force stockholder consideration of a
proposal over the opposition of the Inference Delaware Board of Directors by
calling a special meeting of stockholders prior to such time as the Inference
Delaware Board of Directors believed such consideration to be appropriate.  By
eliminating the use of written consent procedure and the ability of stockholders
to call a special meeting, Inference Delaware intends to encourage persons
seeking to acquire control of Inference Delaware to initiate such an acquisition
through arms'-length negotiations with Inference Delaware's management and Board
of Directors.

          The provisions restricting stockholder action by written consent and
the elimination of the stockholders' ability to call special meetings may have
the effect of delaying consideration of a stockholder proposal until the next
annual meeting unless a special meeting is called by the Inference Delaware
Board of Directors.  Because elimination of the procedures for stockholders to
act by written consent or to call special meetings could make more difficult an
attempt to obtain control of Inference Delaware, such action could have the
effect of discouraging a third party from making a tender offer or otherwise
attempting to obtain control of Inference Delaware.  Because tender offers for
control usually involve purchase prices higher than the prevailing market price,
the provisions restricting stockholder action by written consent and the
elimination of the stockholders' ability to call special meetings may have the
effect of preventing or delaying a bid for Inference Delaware's shares which
could be beneficial to Inference Delaware and its stockholders.  Elimination of
the written consent procedure also means that a meeting of stockholders would be
required in order for Inference Delaware stockholders to replace the Board.  The
restriction on the ability of stockholders to call a special meeting means that
a proposal to replace the Board could be delayed until the next annual meeting.
These provisions thus will make the removal of directors more difficult.


          Number of Directors.  The Inference California Articles of
Incorporation provide for a flexible number of directors, not less than five (5)
nor more than nine (9), with the exact number to be fixed by approval of the
Inference Board of Directors or Inference's shareholders.  The Inference
Delaware Certificate of Incorporation provides for a minimum of five (5)
directors and a maximum of eleven (11) directors, with the number of directors
to be set as determined in the Inference Delaware Bylaws.  Under the Inference
Delaware Bylaws, the size of Inference Delaware's Board of Directors may be
changed by the Board of Directors as well as by vote of the stockholders.

          Monetary Liability of Directors.  The Inference California Articles of
Incorporation and the Inference Delaware Certificate of Incorporation both
provide for the elimination of personal monetary liability of directors to the
fullest extent permissible under the laws of each corporation's respective state
of incorporation.  The provision eliminating monetary liability of directors set
forth in the Inference Delaware Certificate of Incorporation is potentially more
expansive, in that it incorporates future amendments to the Delaware GCL with
respect to the elimination of such liability.

SIGNIFICANT DIFFERENCES BETWEEN THE CORPORATION LAWS OF CALIFORNIA AND DELAWARE

          The GCL and Delaware GCL differ in many respects.  It is not practical
to summarize all of such differences in this Proxy Statement, but some of the
principal differences which could materially affect the rights of shareholders
are discussed below.

                                       29
<PAGE>
 
          Actions Required to Change Size of Board of Directors.  Under the GCL,
although changes in the number of directors must normally be approved by the
shareholders, a corporation's articles of incorporation or bylaws may include a
provision that sets forth a permissible range in the number of directors within
which the board of directors may fix the exact number of directors without
shareholder approval.  Such range must be such that the highest number is equal
to one less than twice the lowest number.  Under the Delaware GCL, a
corporation's certificate of incorporation may authorize the board of directors
to change the authorized number of directors by amendment to the bylaws or in
the manner provided in the bylaws, and there is no requirement that the Board's
discretion be limited to within a permissible range.  The Inference Delaware
Certificate of Incorporation sets a minimum and maximum number of directors,
sets the exact number of directors initially, and provides that the number of
directors may be changed as provided in the Inference Delaware Bylaws.  Thus,
the size of Inference Delaware's Board of Directors may be changed by the Board
of Directors as well as by vote of the stockholders.

          Cumulative Voting.  Neither shareholders of Inference California nor
stockholders of Inference Delaware are entitled to cumulate votes in an election
of directors.

          Classified Board of Directors.  A classified board is one on which a
certain number, but not all, of the directors are elected on a rotating basis
each year.  Under the GCL, directors generally are elected annually; however,
corporations such as Inference California that have 800 or more shareholders of
record and have their stock listed on the NASDAQ National Market are permitted
to designate a classified board by adopting amendments to their articles or
bylaws, which amendments must be approved by a majority of the outstanding
shares.  The Delaware GCL permits, but does not require, a classified board of
directors with staggered terms under which one-half of the directors are elected
for terms of two or three years, respectively.  This method of electing
directors makes a change in the composition of the board of directors, and a
potential change in control of a corporation, a lengthier and more difficult
process.  Both the Inference California Articles of Incorporation and the
Inference Delaware Certificate of Incorporation provide for two and three
classes of directors, respectively.

          Removal of Directors.  Under the GCL, any director or the board of
directors may be removed, with or without cause, with the approval of a majority
of the outstanding shares entitled to vote.  However, where the board is
classified, no director may be removed if the number of votes cast against the
removal would be sufficient to elect the director under cumulative voting
(regardless of whether shares may otherwise be voted cumulatively) and certain
other requirements are met.  Under the Delaware GCL, unless the certificate of
incorporation provides otherwise, a director on a classified board may be
removed only for cause.  The Inference Delaware Certificate of Incorporation
both provides for a classified board and eliminates the right of stockholders to
remove directors without cause.  Accordingly, stockholders of Inference Delaware
will not have the right to remove directors without cause.

          Written Consent of Shareholders.  Both the GCL and Delaware GCL
provide that the shareholders of a corporation may take action by written
consent without a meeting, unless the corporation's charter documents provide
otherwise.  Both the Inference California Articles of Incorporation and the
Inference Delaware Certificate of Incorporation explicitly prohibit stockholder
actions by written consent.

          Power to Call Special Shareholders' Meetings.  Under the GCL, a
special meeting of shareholders may be called by the board of directors, the
chairman of the board, the president, the holders of shares entitled to cast not
less than ten percent of the votes at such meeting and such additional persons
as are authorized by the articles of incorporation or the bylaws.  Under the
Delaware GCL, a special meeting of stockholders may be called by the board of
directors or by any other person authorized to do so in the certificate of
incorporation or the bylaws.  The Inference Delaware Certificate of
Incorporation and Inference Delaware Bylaws do not contain provisions granting
stockholders the right to call a special meeting of stockholders.  Because the
right of stockholders to call a special meeting is not set forth in the
Inference Delaware Certificate of Incorporation or Inference Delaware Bylaws,
stockholders will not be able to call a special meeting of stockholders to vote
on a transaction unless the Board approves the calling of such a meeting.

                                       30
<PAGE>
 
          Stockholder Approval of Certain Business Combinations.  In the last
several years, a number of states (but not California) have adopted special laws
designed to make certain kinds of "unfriendly" corporate takeovers, or other
transactions involving a corporation and one or more of it significant
shareholders, more difficult.  Generally, Section 203 of the Delaware GCL
("Section 203") prohibits a publicly-held Delaware corporation from engaging in
a "business combination" with an "interested stockholder" for a period of three
(3) years after the date of the transactions in which the person became an
interested stockholder, unless (i) prior to the date at which the person becomes
an interested stockholder, the Board of Directors approves such transaction or
business combination, (ii) the interested stockholder acquires more than 85% of
the outstanding voting stock of the corporation (excluding shares held by
directors who are officers or held in certain employee stock plans) upon
consummation of such a transaction, or (iii) the business combination is
approved by the Board of Directors and by two-thirds of the outstanding voting
stock of the corporation (excluding shares held by the interested stockholder)
at a meeting of stockholders (and not by written consent).  A "business
combination" includes a merger, asset sale or other transaction resulting in a
financial benefit to such interested stockholder.  For purposes of Section 203,
"interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years prior, did own) 15% or more of the
corporation's voting stock.

          Filling Vacancies on the Board of Directors.  Under the GCL, unless
otherwise provided in a corporation's articles of incorporation or bylaws, any
vacancy on the board of directors other than one created by removal of a
director may be filled by the board.  If the number of directors then in office
is less than a quorum, a vacancy may be filled by the unanimous written consent
of the directors then in office, by the affirmative vote of a majority of the
directors at a meeting held pursuant to notice or waivers of notice or by a sole
remaining director.  A vacancy created by removal of a director may be filled by
the board only if so authorized by a corporation's articles of incorporation or
by a bylaw approved by the corporation's shareholders.  Inference California's
Bylaws do not permit directors to fill vacancies created by removal of a
director.  Under the Delaware GCL, vacancies and newly created directorships may
be filled by a majority of the directors then in office or a sole remaining
director (even though less than a quorum) unless otherwise provided in the
certificate of incorporation or bylaws (and unless the certificate of
incorporation directs that a particular class is to elect such director, in
which case any other directors elected by such class, or a sole remaining
director, shall fill such vacancy).

          Loans to Officers and Employees.  Under the GCL, any loan or guaranty
to or for the benefit of a director or officer of the corporation or its parent
requires approval of the shareholders unless such loan or guaranty is provided
under an employee benefit plan approved by shareholders owning a majority of the
outstanding shares of the corporation. In addition, under the GCL, shareholders
of any corporation with 100 or more shareholders of record may approve a bylaw
authorizing the board of directors alone to approve loans or guaranties or
employee benefit plans to or on behalf of officers (whether or not such officers
are directors) if the board determines that any such loan or guaranty or
employee benefit plan may reasonably be expected to benefit the corporation.
The Inference California Bylaws authorize such loans or guaranties.  Under the
Delaware GCL, a corporation may make loans to, guarantee the obligations of or
otherwise assist its officers or other employees and those of its subsidiaries
(including directors who are also offices or employees) when such action, in the
judgment of the directors, may reasonably be expected to benefit the
corporation.

          Indemnification and Limitation of Liability.  California and Delaware
have similar laws respecting indemnification by a corporation of its officers,
directors, employees and other agents.  The laws of both states also permit,
with certain exceptions, corporations to adopt a provision in their articles or
certificate of incorporation eliminating the liability of a director to the
corporation or its shareholders for monetary damages for breach of the
director's fiduciary duty of care.  There are nonetheless certain differences
between the laws of the two states respecting indemnification and limitation of
liability.

          The Inference California Articles of Incorporation eliminate the
liability of directors to the corporation to the fullest extent permissible
under the GCL.  The GCL does not permit the elimination of monetary liability
where such liability is based on:  (a) intentional misconduct or knowing and
culpable violation of law; (b) acts or omissions that a director believes to be
contrary to the best interests of the corporation or its shareholders, or that
involve the absence of good faith on the part of the director; (c) receipt of an
improper personal benefit; (d) acts or omissions that show reckless disregard
for the director's duty to the corporation or its shareholders, where the
director in the ordinary course of performing a director's duties should be
aware of a risk of serious injury to the corporation or its shareholders; (e)
acts or omissions that constitute an unexcused pattern of inattention that
amounts to an abdication of the director's duty to the corporation and its
shareholders; (f) interested transactions between the corporation and a director
in which a director has a material financial interest; and (g) liability for
improper distributions, loans or guarantees.

                                       31
<PAGE>
 
          The Inference Delaware Certificate of Incorporation also eliminates
the liability of directors to the fullest extent permissible under the Delaware
GCL, as such law exists currently or as it may be amended in the future.  Under
the Delaware GCL, such a provision may not eliminate or limit director monetary
liability for (a) breaches of the director's duty of loyalty to the corporation
or its stockholders, (b) acts or omissions not in good faith or involving
intentional misconduct or knowing violations of law, (c) the payment of unlawful
dividends or unlawful stock repurchases or redemptions; or (d) transactions from
which the director received an improper personal benefit.  Such limitation of
liability provision also may not limit a director's liability for violation of,
or otherwise relieve Inference Delaware or its directors from the necessity of
complying with, federal or state securities laws, or affect the availability of
non-monetary remedies such as injunctive relief or rescission.

          The GCL permits indemnification of expenses incurred in derivative or
third-party actions, except that with respect to derivative actions (a) no
indemnification may be made without court approval when a person is adjudged
liable to the corporation in the performance of that person's duty to the
corporation and it shareholders, unless a court determines such person is fairly
and reasonably entitled to indemnity for expenses, and then such indemnification
may be made only to the extent that such court shall determine, and (b) no
indemnification may be made without court approval in respect of amounts paid or
expenses incurred in settling or otherwise disposing of a threatened or pending
action or expenses incurred in defending a pending action which is settled or
otherwise disposed of without court approval.

          Indemnification is permitted by the GCL only for actions taken in good
faith and believed to be in the best interests of the corporation and its
shareholders and not in violation of the requirements described above, as
determined by a majority vote of a quorum of the disinterested directors,
independent legal counsel (if a quorum of disinterested directors is not
obtainable), a majority vote of a quorum of the shareholders (excluding shares
owned by the indemnified party), or the court handling the action.  The GCL
requires indemnification when the individual has successfully defended the
action on the merits.

          The Delaware GCL generally permits indemnification for expenses
incurred in the defense or settlement of a derivative or third-party action,
provided there is a determination by a quorum of the disinterested directors, by
independent legal counsel or by a majority vote of a quorum of the shareholders
that the person seeking indemnification acted in good faith and in a manner
reasonably believed to be in, or (in contrast to the GCL) not opposed to, the
best interests of the corporation.  Without court approval, however, no
indemnification may be made in respect of any derivative action in which such a
person is adjudged liable for negligence or misconduct in the performance of his
or her duty to the corporation.  The Delaware GCL requires indemnification of
expenses when the individual being indemnified has successfully defended the
action on the merits or otherwise.

          California corporations may include in their articles of incorporation
a provision which extends the scope of indemnification through agreements,
bylaws, or other corporate action beyond that specifically authorized by statute
except to the extent expressly prohibited by statute.  The Inference California
Articles of Incorporation include such a provision.

          The Delaware GCL states that the indemnification provided by statute
shall not be deemed exclusive of any other rights under any bylaw, agreement,
vote of stockholders or disinterested directors or otherwise.

          The indemnification and limitation of liability provisions of the GCL,
and not the Delaware GCL will apply to actions of directors and officers of
Inference California taken prior to the Reincorporation.

          Inspection of Shareholders List.  Both the GCL and the Delaware GCL
allow any shareholder to inspect the shareholders' list for a purpose reasonably
related to such person's interest as a shareholder.  The GCL provides, in
addition, for an absolute right to inspect and copy the corporation's
shareholder list by persons holding an aggregate of five percent or more of a
corporation's voting shares, or shareholders holding an aggregate of one percent
or more of such shares who have filed a Schedule 14A with the Securities and
Exchange Commission relating to the election of directors.  The Delaware GCL
does not provide for any such absolute right of inspection, and no such right is
granted under the Inference Delaware Certificate of Incorporation or Inference
Delaware Bylaws.  Lack of access to shareholder records even though unrelated to
the shareholder's interest as a shareholder, could result in impairment of the
shareholder's ability to coordinate opposition to management proposals,
including proposals with respect to a change in control of Inference.

                                       32
<PAGE>
 
          Dividends and Repurchases of Shares.  The GCL dispenses with the
concepts of par value of shares as well as statutory definitions of capital,
surplus and the like.  The concepts of par value, capital and surplus are
retained under the Delaware GCL.

          Under the GCL, a corporation may not make any distribution (including
dividends, whether in cash or other property, and repurchases of its shares)
unless either the corporation's retained earnings immediately prior to the
proposed distribution equal or exceed the amount of the proposed distribution
or, immediately after giving effect to such distribution, the corporation's
assets (exclusive of goodwill, capitalized research and development expenses and
deferred charges) would be at least equal to 1.25 times its liabilities (not
including deferred taxes, deferred income and other deferred credits), and the
corporation's current assets would be at least equal to its current liabilities
(or 1.25 times its current liabilities if the average pre-tax and pre-interest
expense earnings for the preceding two fiscal years were less than the average
interest expense for such years).  Such tests are applied to California
corporations on a consolidated basis.

          The Delaware GCL permits a corporation to declare and pay dividends
out of surplus or, if there is no surplus, out of net profits for the fiscal
year in which the dividend is declared and/or for the preceding fiscal year as
long as the amount of capital of the corporation following the declaration and
payment of the dividend is not less than the aggregate amount of the capital
represented by the issues and outstanding stock of all classes having a
preference upon the distribution of assets.  In addition, the Delaware GCL
generally provides that a corporation may redeem or repurchase its shares only
if such redemption or repurchase would not impair the capital of the corporation
or if it repurchases shares having a preference upon the liquidation of assets
and it retires such shares upon acquisition.

          Shareholder Voting.  Both the GCL and the Delaware GCL generally
require that a majority of the shareholders of both acquiring and target
corporations approve statutory mergers.  The Delaware GCL does not require a
stockholder vote of the surviving corporation in a merger (unless the
corporation provides otherwise in its certificate of incorporation) if (a) the
merger agreement does not amend the existing certificate of incorporation, (b)
each share of the surviving corporation outstanding before the merger is an
identical outstanding or treasury share after the merger, and (c) the number of
shares to be issued by the surviving corporation in the merger does not exceed
20% of the shares outstanding immediately prior to the merger.  The GCL contains
a similar exception to its voting requirements for reorganizations where
shareholders or the corporation itself, or both, immediately prior to the
reorganization will own immediately after the reorganization equity securities
constituting more than five-sixths of the voting power of the surviving or
acquiring corporation or its parent entity.

          Both the GCL and the Delaware GCL also require that a sale of all or
substantially all of the assets of a corporation be approved by a majority of
the voting shares of the corporation transferring such assets.

          With certain exceptions, the GCL also requires that mergers,
reorganizations, certain sales of assets and similar transactions be approved by
a majority vote of each class of shares outstanding.  In contrast, the Delaware
GCL generally does not require class voting, except in certain transactions
involving an amendment to the certificate of incorporation which adversely
affects a specific class of shares.  Should Inference authorize and issue shares
of a new class of capital stock, the holders thereof would vote with the holders
of the Inference Delaware Common Stock on proposals not adversely affecting the
Inference Delaware Common Stock.  In such event the holders of Inference
Delaware Common Stock, if in the minority, would be unable to control the
outcome of a vote, and, if in the majority, would be able to control the outcome
of such a vote.

          The GCL also requires that holders of nonredeemable common stock
receive nonredeemable common stock in a merger of the corporation with the
holder of more than 50% but less than 90% of each common stock or its affiliate
unless all of the holders of such common stock consent to the transaction.  This
provision of the GCL may have the effect of making a "cash-out" merger by a
majority shareholder more difficult to accomplish.  Although the Delaware GCL
does not parallel the GCL in this respect, under some circumstances Section 203
of the Delaware GCL can provide similar protection against coercive two-tiered
bids for a corporation in which the stockholders are not treated equally.  See
"---Stockholder Approval of Certain Business Combinations."

                                       33
<PAGE>
 
          The GCL also provides that, except in certain circumstances, when a
tender offer or a proposal for a reorganization or for a sale of assets is made
by an interested party (generally a controlling or managing party of the target
corporation), an affirmative opinion in writing as to the fairness of the
consideration to be paid to the shareholders must be delivered to shareholders.
This fairness opinion requirement does not apply to a corporation which does not
have shares held of record by at least 100 persons, or to a transaction which
has been qualified under California state securities laws.  Furthermore, if a
tender of shares or vote is sought pursuant to an interested party's proposal
and a later proposal is made by another party at least ten days prior to the
date of acceptance of the interested party's proposal, the shareholders must be
informed of the later proposal and be afforded a reasonable opportunity to
withdraw any vote, consent or proxy, or to withdraw any tendered shares.  The
Delaware GCL has no comparable provision, and the stockholders of Inference
Delaware might, therefore, be deprived of an opportunity to consider such other
proposal.

          Interested Director Transactions.  Under both the GCL and the Delaware
GCL, certain contracts or transactions in which one or more of a corporation's
directors has an interest are not void or voidable because of such interest
provided that certain conditions, such as obtaining the required approval and
fulfilling the requirements of good faith and full disclosure, are met.  With
certain exceptions, the conditions are similar under the GCL and the Delaware
GCL.  Under the GCL and the Delaware GCL, (a) either the shareholders or the
board of directors must approve any such contract or transaction after full
disclosure of the material facts, and, under the GCL only, in the case of board
approval, the contract or transaction must also be "just and reasonable" to the
corporation, or (b) the contract or transaction must have been just and
reasonable or fair as to the corporation at the time it was approved.  In the
latter case, the GCL explicitly places the burden of proof on the interested
director to prove that a transaction is "just and reasonable."  Under the GCL,
if shareholder approval is sought, the interested director is not entitled to
vote his shares at a shareholder meeting with respect to any action regarding
such contact or transaction.  If board approval is sought, the contractor
transaction must be approved by a majority vote of a quorum of the directors,
without counting the vote of any interested directors (except that interested
directors may be counted for purposes of establishing a quorum).  Under the
Delaware GCL, if board approval is sought, the contract or transaction must be
approved by a majority of the disinterested directors (even though less than a
majority of a quorum).  Therefore, certain transactions that the Board of
Directors of Inference California might not be able to approve because of the
number of interested directors could be approved by a majority of the
disinterested directors of Inference Delaware, although less than a majority of
a quorum.  Inference is not aware of any plans to propose any transaction
involving directors of Inference which could not be so approved under the
California GCL but could be so approved under the Delaware GCL.

          Voting by Ballot.  The GCL provides that the election of directors may
proceed in the manner described in a corporation's bylaws.  Inference
California's Bylaws provide that the election of directors at a shareholder's
meeting may be by voice vote or ballot, unless prior to such vote a shareholder
demands a vote by ballot, in which case such vote must be by ballot.  Under the
Delaware GCL, the right to vote by written ballot may be restricted if so
provided in the certificate of incorporation.  The Inference Delaware
Certificate of Incorporation provides that election of directors need not be by
ballot unless the Inference Delaware Bylaws provide that elections shall be by
ballot.  It may be more difficult for a stockholder to contest the outcome of a
vote which has not been conducted by written ballot.

          Shareholder Derivative Suits.  The GCL provides that a shareholder
bringing a derivative action on behalf of a corporation need not have been a
shareholder at the time of the transaction in question, provided that certain
tests are met.  Under the Delaware GCL, a stockholder may only bring a
derivative action on behalf of the corporation if the stockholder was a
stockholder of the corporation at the time of the transaction in question or his
or her stock thereafter devolved upon him or her by operation of law.  The GCL
also provides that the corporation or the defendant in a derivative suit may
make a motion to the court for an order requiring the plaintiff shareholder to
furnish a security bond.  Delaware does not have a similar bonding requirement.

                                       34
<PAGE>
 
          Dissenters' or Appraisal Rights.  Under both the GCL and the Delaware
GCL, a shareholder of a corporation participating in certain major corporate
transactions may, under varying circumstances, be entitled to dissenters' or
appraisal rights pursuant to which such shareholder may receive cash in the
amount of the fair market value of his or her shares in lieu of the
consideration he or she would otherwise receive in the transaction.  Under the
Delaware GCL, such appraisal rights are not available (a) with respect to the
sale, lease or exchange of all or substantially all of the assets of a
corporation, (b) with respect to a merger or consolidation by a corporation the
shares of which are either listed on a national securities exchange or are held
of record by more than 2,000 holders if such stockholders receive only shares of
the surviving corporation or shares of any other corporation which are either
listed on a national securities exchange or held of record by more than 2,000
holders, plus cash in lieu of fractional shares, or (c) to stockholders of a
corporation surviving a merger if vote of the stockholders of the surviving
corporation is not required to approve the merger because the merger agreement
does not amend the existing certificate of incorporation, each share of the
surviving corporation outstanding prior to the merger is an identical
outstanding or treasury share after the merger, and the number of shares to be
issued in the merger does not exceed 20% of the shares of the surviving
corporation outstanding immediately prior to the merger and if certain other
conditions are met.

          The limitations on the availability of appraisal rights under the GCL
are different from those under the Delaware GCL.  Shareholders of a California
corporation whose shares are listed on a national securities exchange or on a
list of over-the-counter margin stocks issued by the Board of Governors of the
Federal Reserve System generally do not have such appraisal rights unless the
holders of at least 5% of the class of outstanding shares claim the right or the
corporation or any law restricts the transfer of such shares.  Appraisal rights
are unavailable, however, if the shareholders of a corporation or the
corporation itself, or both, immediately prior to the reorganization will own
immediately after the reorganization equity securities constituting of more than
five-sixths of the voting power of the surviving or acquiring corporation or its
parent entity (as will be the case in the Reincorporation).  The GCL does in
general afford appraisal rights in sale of asset reorganizations.

          Appraisal or dissenters' rights are not available to shareholders of
Inference California with respect to the Reincorporation.

          Dissolution.  Under the GCL, shareholders holding 50% or more of the
total voting power may authorize a corporation's dissolution, with or without
the approval of the corporation's board of directors, and this right may not be
modified by the articles of incorporation.  Under the Delaware GCL, unless the
board of directors approves the proposal to dissolve, the dissolution must be
approved by stockholders holding 100% of the total voting power of the
corporation.  Only if the dissolution is initiated by the board of directors may
it be approved by a simple majority of the corporation's stockholders.  In the
event of such a board-initiated dissolution, the Delaware GCL allows a Delaware
corporation to include in its certificate of incorporation a supermajority
voting requirement in connection with dissolutions.  The Inference Delaware
Certificate of Incorporation contains no such supermajority voting requirement,
however, and a majority of shares voting at a meeting at which a quorum is
present would be sufficient to approve a dissolution of Inference Delaware which
had previously been approved by its Board of Directors.

APPLICATION OF THE GCL TO DELAWARE CORPORATIONS

          Under Section 2115 of the GCL, certain foreign corporations (i.e.,
corporations not organized under the GCL) are placed in a special category if
they have characteristics of ownership and operation which indicate that they
have significant contacts with California.  So long as a Delaware or other
foreign corporation is in this special category, and it does not qualify for one
of the statutory exemptions, it is subject to a number of key provisions of the
GCL applicable to corporations incorporated in California.  Among the more
important provisions are those relating to the election and removal of
directors, cumulative voting, classified boards of directors, standards of
liability and indemnification of directors, distributions, dividends and
repurchases of shares, shareholder meetings, approval of certain corporate
transactions, dissenters' rights and inspection of corporate records.  See "---
Significant Differences Between the Corporation Laws of California and
Delaware."

          Exemptions from Section 2115 are provided for corporations whose
shares are listed on a major national securities exchange, such as the NASDAQ
National Market, and which have 800 or more shareholders of record.  Inference
Delaware will be exempt from Section 2115 following the Reincorporation because
the Inference Delaware Common Stock will be traded on the NASDAQ National Market
and owned by more than 800 holders.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

          The following discussion is a summary of the federal income tax
consequences expected to result to holders of Inference Common Stock from the
receipt of Inference Delaware Common Stock in connection with the
Reincorporation and reflects the opinion of O'Melveny & Myers, counsel to
Inference.  The summary is based on current provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), applicable treasury regulations, judicial
authority and administrative rulings and practice.  There can be no assurance
that the IRS will not take a contrary view, and no ruling from the IRS has been
or will be sought.  Legislative, judicial or administrative changes or
interpretations may be forthcoming that could alter or modify the statements and
conclusions set forth herein.  Any such changes or interpretations may or may
not be retroactive and could affect the tax consequences to holders.

          The tax treatment of an Inference shareholder may vary depending upon
his or her particular situation.  Certain holders (including insurance
companies, tax-exempt organizations, financial institutions or broker-dealers,
foreign corporations and persons who are not citizens or residents of the United
States) may be subject to special rules not discussed below.  EACH SHAREHOLDER
SHOULD CONSULT SUCH SHAREHOLDER'S OWN TAX ADVISOR AS TO THE SPECIFIC TAX
CONSEQUENCES OF THE REINCORPORATION ON SUCH SHAREHOLDER, INCLUDING THE
APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES IN SUCH TAX LAWS.

THE MERGER

          Subject to the limitations, qualifications, and exceptions described
herein, and assuming the Reincorporation qualifies as a reorganization within
the meaning of Section 368(a) of the Code, the following tax consequences
generally should result therefrom:

     (a) No gain or loss should be recognized by holders of Inference Common
  Stock upon receipt of Inference Delaware Common Stock pursuant to the
  Reincorporation;

     (b) The aggregate tax basis of the Inference Delaware Common Stock received
  by each shareholder in the Reincorporation should be equal to the aggregate
  tax basis of the Inference Common Stock exchanged therefor; and

     (c) The holding period of the Inference Delaware Common Stock received by
  each shareholder of Inference California should include the period for which
  such shareholder held the Inference Common Stock exchanged therefor, provided
  that such Inference California stock was held by such shareholder as a capital
  asset at the time of the Reincorporation.

          Inference has not requested a ruling from the IRS with respect to the
federal income tax consequences of the Reincorporation under the Code. Inference
has, however, received an opinion from legal counsel substantially to the effect
that the Reincorporation will qualify as a reorganization within the meaning of
Section 368(a) of the Code, and as to certain other tax matters (the "Tax
Opinion"). The Tax Opinion will neither bind the IRS nor preclude it from
asserting a contrary position. In addition, the Tax Opinion will be subject to
certain assumptions and qualifications and will be based upon the truth and
accuracy of representations made by Inference Delaware, Inference California and
certain shareholders of Inference California. Of particular importance will be
assumptions and representations relating to the requirement (the "continuity of
interest" requirement) that the shareholders of Inference California retain,
through ownership of Inference Delaware Common Stock, a significant equity
interest in Inference California's business after the Reincorporation.

          A successful IRS challenge to the reorganization status of the
Reincorporation would result in a shareholder recognizing gain or loss with
respect to each share of Inference Common Stock exchanged in the Reincorporation
equal to the difference between that shareholder's basis in such share and the
fair market value, as of the time of the Reincorporation, of the Inference
Delaware Common Stock received in exchange therefor. In such event, a
shareholder's aggregate basis in the shares of Inference Delaware Common Stock
received in the exchange would equal such fair market value, and such
shareholder's holding period for such shares would not include the period during
which such shareholder held Inference Common Stock.

          EACH INFERENCE SHAREHOLDER SHOULD CONSULT HIS OR HER TAX ADVISOR WITH
RESPECT TO THE TAX CONSEQUENCES TO HIM OR HER, INCLUDING THE TAX CONSEQUENCES
UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS, OF THE REINCORPORATION.

REQUIRED VOTE

          The affirmative vote of the holders of a majority of the shares of the
Company's Common Stock present at the Annual Meeting in person or by proxy and
entitled to vote is required to approve the reincorporation of the Company in
the State of Delaware.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE REINCORPORATION OF
THE COMPANY IN THE STATE OF DELAWARE.


                       COMPLIANCE WITH SECTION 16(A) OF
                      THE SECURITIES EXCHANGE ACT OF 1934

          Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's directors and executive officers, and persons who own more than ten
percent of a registered class of the Company's equity securities, to file with
the Securities and Exchange Commission ("SEC") initial reports of ownership and
reports of changes in ownership of Common Stock and other equity securities of
the Company. Executive officers, directors and holders of more than ten percent
of the Company's Common Stock are required by SEC regulation to furnish the
Company with copies of all Section 16(a) forms they file.

          Except as provided below, to the Company's knowledge, based solely
upon its review of the copies of such reports furnished to the Company and
written representations that no other reports were required, during the fiscal
year ended January 31, 1996, all Section 16(a) filing requirements applicable to
its executive officers, directors and holders of more than ten percent of the
Company's Common Stock were satisfied. Anthony Sun and C. Scott Gibson
inadvertently did not file their Form 3s with the SEC on the date of the
effectiveness of the Company's initial public offering, but each of such
directors did file their Form 3s within a few days thereafter.

                 SHAREHOLDER PROPOSALS FOR 1997 ANNUAL MEETING

          Any proposal of a shareholder intended to be presented at the
Company's 1997 annual meeting and included in the proxy statement and form of
proxy for that meeting must be received by the Company no later than January 20,
1997.


                                 OTHER MATTERS

          The Board of Directors knows of no other matters other than those
described herein that will be presented for consideration at the Annual Meeting.
If, however, any other business shall properly come before the Annual Meeting,
the proxy holders will, as to such items, vote the shares represented by proxies
in accordance with their best judgment.

          2.   PURPOSE, SUMMARY. The purpose of this Plan is to assist Qualified
Employees in acquiring a stock ownership interest in the Company pursuant to a
plan which is intended to qualify as an "employee stock purchase plan" under
Section 423 of the Code. Under this Plan, Participants are deemed to have been
granted options to purchase shares of Common Stock. Participants may designate a
certain amount of their Base Pay to be set aside during the Offering Period for
the purpose of purchasing Common Stock. At the end of the Offering Period, the
Participants are deemed to have exercised their options using the funds set
aside for them and the Company issues share certificates to them. The plan is
intended, among other things, to provide an additional incentive to
Participants, through the ownership of Common Stock, to achieve business goals
that would increase stock values and to remain in the employ of the Company or a
Subsidiary.     

    
          3.   STOCK SUBJECT TO THIS PLAN.  Subject to the provisions of Section
10 hereof (relating to adjustments upon changes in capitalization), the total
number of shares available under this Plan is 500,000 shares of Common Stock.
Such shares may be authorized but unissued shares.     

    
          4.   GRANT OF OPTIONS.     

    
               (a)  IN GENERAL.  Commencing August 1, 1996 and continuing while
this Plan remains in force, the Company will offer on the first day of each
quarter of a calendar year (and on August 1, 1996) options to purchase shares of
Common Stock under this Plan to all Participants (each a "Grant Date"). The term
of each option ("Offering Period") shall be 3 months (2 months for the third
quarter of the 1996 calendar year), the last day of which shall be the last day
of the calendar quarter in which such option was granted (each an "Exercise
Date"). The number of shares subject to each option and deemed to be purchased
by each Participant shall be the quotient, rounded down to the nearest whole
number, of (i) the aggregate payroll deductions authorized by each Participant
in accordance with Section 4(b) below made during the Offering Period, divided
by (ii) the Option Price. The grant of options hereunder is subject to the
approval of the Plan by the shareholders of the Company. If shareholder approval
is not received by or before August 1, 1996, this Plan shall be deemed to be
terminated and no options shall be granted hereunder.    

    
               (b)  ELECTION TO PARTICIPATE; PAYROLL DEDUCTION AUTHORIZATION.
Except as provided in Section 4(d) below, a Qualified Employee may participate
in this Plan only by means of payroll deductions. Each Qualified Employee who
elects to participate in this Plan shall deliver to the Company, no later than
the 15th day of the month next preceding a Grant Date (or July 15 for the third
quarter of the 1996 calendar year, or the next business day following such date
if such day is not a business day), a written payroll deduction authorization in
a form approved by the Company pursuant to which he gives notice of his election
to participate in this Plan as of the next following Grant Date, and whereby he
designates a stated amount to be deducted from his Base Pay on each payday
during the next Offering Period and credited to his account under this Plan
("Account"). The stated amount to be deducted from a Participant's Base Pay may
not be less than $10.00 per pay period. The aggregate stated amount for any
Offering Period may not exceed either of the following: (i) ten percent (10%) of
the Participant's Base Pay during the Offering Period; or (ii) an amount which
will result in noncompliance with the $25,000 limitation stated in Section 4(c)
below. Payroll deduction authorizations may not be changed during the Offering
Period. In the event the number of shares of Common Stock subject to options
during a Offering Period exceeds the number of shares then available under this
Plan, the available shares shall be allocated among the Participants in
proportion to the balance of their Accounts at the end of the Offering Period,
and any amounts credited to their Accounts after giving effect to shares
purchased that year shall be refunded to the Participants.    

    
               (c)  $25,000 LIMITATION.  No Participant shall be deemed to have
been granted options under this Plan which would permit his rights to purchase
Common Stock under this Plan or any other employee stock purchase plan of the
Company or any Subsidiary to accrue at a rate which exceeds $25,000 of Fair
Market Value of Common Stock for any calendar year. For purposes of this
subsection (c), the right to purchase Common Stock under an option accrues when
the option (or any portion thereof) becomes exercisable, and the right to
purchase Common Stock which has accrued during one Offering Period may not be
carried over to any subsequent Offering Period.    

    
                                   A-2     
<PAGE>
 
    
               (d)  LEAVES OF ABSENCE.  During leaves of absence approved by the
Company and meeting the requirements of Regulation Section 1.421-7(h)(2) under
the Code, a Participant may continue participation in this Plan by making cash
payments to the Company on the Company's normal paydays equal to the reduction
in his payroll deduction attributable to his leave.     

    
          5.   EXERCISE OF OPTIONS.     

    
               (a)  IN GENERAL.  On each Exercise Date, each Participant
automatically and without any act on his part will be deemed to have exercised
his option to the extent that the balance then credited to his Account is
sufficient to purchase whole shares of Common Stock at the Option Price. The
Company shall promptly refund to the Participant any balance remaining in his
Account, without interest thereon, after giving effect to the purchase of such
whole shares.     

    
               (b)  "OPTION PRICE" DEFINED.  The Option Price per share to be
paid by each Participant upon exercise of his option shall be an amount equal to
85% of the Fair Market Value of Common Stock on the Grant Date or on the
Exercise Date (or the date of the Participant's Retirement, death or Total
Disability if any such event occurs), whichever amount is less.     

    
               (c)  DELIVERY OF SHARE CERTIFICATES.  Subject to Section 5(d)
below, the Company will deliver to each Participant a certificate issued in the
Participant's name for the number of shares with respect to which his option was
exercised. The Company will deliver the certificate as soon as practicable
following the Exercise Date.     

    
               (d)  GOVERNMENT REGULATIONS.  This Plan, the granting of options
under this Plan and the issuance of Common Stock pursuant hereto are subject to
all applicable federal and state laws, rules and regulations and to such
approvals by any regulatory or governmental agency which may, in the opinion of
counsel for the Company, be necessary or advisable in connection therewith.
Without limiting the generality of the foregoing, no options may be granted
under this Plan, and no shares may be issued by the Company, unless and until,
in each such case, all legal requirements applicable to the grant or issuance
have, in the opinion of counsel to the Company, been complied with. In
connection with the issuance of Common Stock hereunder, the Participant shall,
if requested by the Company, give assurances satisfactory to counsel to the
Company in respect of such matters as the Company may deem desirable to assure
compliance with all applicable legal requirements.     

    
          6.   WITHDRAWAL FROM THIS PLAN.     

    
               (a)  IN GENERAL.  Any Participant may completely withdraw from
this Plan at any time. A Participant who desires to withdraw from this Plan must
deliver to the Company a notice of withdrawal in a form approved by the Company.
Promptly following the time when the notice of withdrawal is delivered, the
Company will refund to the Participant the amount of the balance of his Account,
without interest thereon, and the Participant's payroll deduction authorization,
interest in this Plan and option under this Plan shall thereupon terminate.     

    
               (b)  ELIGIBILITY FOLLOWING WITHDRAWAL.  A Participant who has
withdrawn from this Plan shall again be eligible to participate in this Plan
upon expiration of the Offering Period during which the Participant 
withdrew.     

    
          7.   TERMINATION OF EMPLOYMENT.     

    
               (a)  TERMINATION OF EMPLOYMENT OTHER THAN BY RETIREMENT, DEATH OR
TOTAL DISABILITY.  If the employment of a Participant by the Company or a
Subsidiary terminates during an Offering Period other than by reason of
Retirement, death or Total Disability, his participation in this Plan
automatically and without any act on his part shall terminate as of the date of
the termination of the Participant's employment. The Company promptly will
refund to the Participant the amount of the balance of his Account, without
interest thereon, and thereupon his interest in and option under this Plan shall
terminate. Nothing in this Plan shall prevent the Company or any Subsidiary from
terminating any Participant's employment.     

    
               (b)  TERMINATION BY RETIREMENT.  If a Participant's employment
terminates during an Offering Period because of Retirement of the Participant,
the Participant may, at his election by written notice to the Company, either
(i) exercise his option as of his Retirement date, in which event the Company
shall apply the balance of his Account to the purchase, at the Option Price, of
whole shares of Common Stock and refund the excess, if any, or (ii) request
payment of the balance of his Account, in which event the Company promptly shall
make such payment, without interest thereon, and thereupon his interest in and
option under this Plan shall terminate.  If the Participant elects to exercise
his option, the date of his Retirement shall be deemed to be the Exercise Date
for the purpose of computing the Option Price.     

    
                                   A-3     
<PAGE>
 
    
               (c)  TERMINATION BY DEATH OR TOTAL DISABILITY.  If a Participant
dies or suffers a Total Disability during an Offering Period, the Participant or
his Personal Representative, as the case may be, by written notice to the
Company, may either (i) exercise the Participant's option as of the date of
death or Total Disability, in which event the Company shall apply the balance of
his Account to the purchase, at the Option Price, of whole shares of Common
Stock and refund the excess, if any, or (ii) request payment of the balance of
the Participant's Account, in which event the Company promptly shall make such
payment to the Participant or his Personal Representative, and thereupon the
Participant's interest in and option under this Plan shall terminate. If the
option is exercised, the date of death or Total Disability shall be deemed to be
the Exercise Date for the purpose of computing the Option Price. If the Company
does not receive such notice within 90 days of the date of Participant's death
or Total Disability, the Participant or his Personal Representative shall be
conclusively presumed to have elected alternative (ii) above and requested the
payment of the balance of the Participant's Account.     

    
          8.   RESTRICTION UPON ASSIGNMENT.  An option granted under this Plan
shall not be transferable otherwise than by will or the laws of descent and
distribution pursuant to Section 7(c) hereof, and is exercisable during the
Participant's lifetime only by the Participant (or his Personal Representative
in the event of the Participant's Total Disability).  The Company will not
recognize any assignment or purported assignment by a Participant of his option
or of any rights under his option or under this Plan.     

    
          9.   NO RIGHTS AS SHAREHOLDER.  With respect to shares of Common Stock
subject to an option, a Participant shall not be deemed to be a shareholder and
shall not have any of the rights or privileges of a shareholder until a
certificate for shares of Common Stock has been issued to the Participant
following the exercise of his option.     

    
          10.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  If the outstanding
shares of Common Stock are increased, decreased or changed into, or exchange
for, a different number or kind of shares or securities of the Company through a
reorganization or merger in which the Company is the surviving entity, or
through a combination, recapitalization, reclassification, stock split, stock
dividend, stock consolidation or otherwise, an appropriate adjustment shall be
made in the number and kind of shares that may be issued under this Plan.     

               Upon the dissolution or liquidation of the Company, or upon a
reorganization, merger, or consolidation of the Company with one or more
corporations as a result of which the Company is not the surviving corporation,
or upon a sale of all or substantially all of the property of the Company to
another corporation, this Plan shall terminate, and any outstanding options
shall terminate and the Company thereupon will promptly refund the balance of
the Participants' Accounts to the Participants, without interest thereon, unless
(i) the Committee shall determine, in its sole and absolute discretion, that any
or all options under this Plan shall accelerate and become immediately
exercisable or (ii) provision shall be made in connection with such transaction
for the assumption of options theretofore granted hereunder, or the substitution
for such options or new options covering the stock of a successor employer
corporation, or a parent or subsidiary thereof, with appropriate adjustments as
to number and kind of shares and prices.  If the Committee determines to
accelerate any or all of the options, the acceleration date designated by the
Committee shall be deemed to be the Exercise Date for the purpose of computing
the option price of the accelerated option.

               In so adjusting Common Stock to reflect such changes, or in
determining that no such adjustment is necessary, the Committee may rely upon
the advice of independent counsel and accountants of the Company, and the
determination of the Committee shall be conclusive. No fractional shares of
stock shall be issued under this Plan on account of any such adjustment.

    
          11.  USE OF FUNDS; NO INTEREST PAID.  All amounts withheld from
Participants' paychecks hereunder and credited to their Accounts will be
included in the general funds of the Company free of any trust or other

to be in full force and effect.     

    
          19.  NO EMPLOYMENT RIGHTS.  The Plan does not, directly or indirectly,
create any right for the benefit of any employee or class of employees to

          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").
 
          2.   Governing Documents.  The Certificate of Incorporation of
Inference Delaware, as in effect immediately prior to the Effective Time, shall

provisions thereof, of the Certificate of Incorporation of the Surviving
Corporation and applicable law.

existence of Inference California shall cease, and Inference Delaware shall

private nature and be subject to all the restrictions, disabilities and duties

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

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

     specified in the preceding sentence shall be required notwithstanding the
     fact that no vote may be required, or that a lesser percentage vote may be
     specified by law or otherwise.    
    
          (D)  Conversion.     
               ---------- 

    
          (1)  Upon compliance with the provisions of paragraph (D)(3) below,
     any Regulated Stockholder (as defined below) shall be entitled to convert,
     at 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
     any successor to such regulation ("REGULATION Y"), and that holds shares of
     Class A Common Stock and Class B Common Stock issued on or prior to
     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 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      

    
                                   C-2     
<PAGE>
 
     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 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 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      

    
                                   C-3     
<PAGE>
 
     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 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.

          The name and mailing address of the incorporator is Susanna Kim, 610
Newport Center Drive, Suite 1700, Newport Beach, California 92660.

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.

          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 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.
