                                PROXY STATEMENT

                                ---------------

     This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of The Immune Response Corporation, a Delaware
corporation (the "Company"), of proxies in the accompanying form to be used at
the Annual Meeting of Stockholders to be held at the offices of the Company,
5935 Darwin Court, Carlsbad, California, on May 22, 1997 and any adjournment
thereof (the "Annual Meeting").  The shares represented by the proxies received
in response to this solicitation and not revoked will be voted at the Annual
Meeting.  A proxy may be revoked at any time before it is exercised by filing
with the Secretary of the Company a written revocation or a duly executed proxy
bearing a later date or by voting in person at the Annual Meeting.  On the
matters coming before the Annual Meeting for which a choice has been specified
by a stockholder by means of the ballot or the proxy, the shares will be voted
accordingly.  If no choice is specified, the shares will be voted FOR the
election of the four nominees for Class II director listed in this Proxy
Statement and FOR the approval of Proposals 2 and 3 described in the Notice of
Annual Meeting and in this Proxy Statement.

     Stockholders of record at the close of business on March 31, 1997 are
entitled to notice of and to vote at the Annual Meeting.  As of the close of
business on such date, the Company had 20,288,722 shares of Common Stock
outstanding and entitled to vote.  Each holder of Common Stock is entitled to
one vote for each share held as of the record date.

     Any stockholder or stockholder's representative who, because of a
disability, may need special assistance or accommodation to allow him or her to
participate at the Annual Meeting, may request reasonable assistance or
accommodation from the Company by contacting The Immune Response Corporation,
Investor Relations, 5935 Darwin Court, Carlsbad, California 92008 (619) 431-
7080.  To provide the Company sufficient time to arrange for reasonable
assistance or accommodation, please submit all requests by May 8, 1997.

     Directors are elected by a plurality vote.  The other matters submitted for
stockholder approval at this Annual Meeting will be decided by the affirmative
vote of a majority of shares present in person or represented by proxy and
entitled to vote on each such matter.  Abstentions with respect to any matter
are treated as shares present or represented and entitled to vote on that matter
and thus have the same effect as negative votes.  If shares are not voted by the
broker who is the record holder of such shares, or if shares are not voted in
other circumstances in which proxy authority is defective or has been withheld
with respect to any matter, these non-voted shares are not deemed to be present
or represented for purposes of determining whether stockholder approval of that
matter has been obtained.

     The expense of printing and mailing proxy materials will be borne by the
Company.  In addition to the solicitation of proxies by mail, solicitation may
be made by certain directors, officers and other employees of the Company by
personal interview, telephone or facsimile.  No additional compensation will be
paid to such persons for such solicitation.  The Company will reimburse
brokerage firms and others for their reasonable expenses in forwarding
solicitation materials to beneficial owners of the Company's Common Stock.  The
Company has retained Beacon Hill Partners, Inc. to assist in the solicitation of
proxies at a cost of approximately $5,000.

     This Proxy Statement and the accompanying form of proxy are being mailed to
stockholders on or about April 18, 1997.

                                    IMPORTANT

     PLEASE MARK, SIGN AND DATE THE ENCLOSED PROXY AND RETURN IT AT YOUR
EARLIEST CONVENIENCE IN THE ENCLOSED POSTAGE-PREPAID RETURN ENVELOPE SO THAT,
WHETHER YOU INTEND TO BE PRESENT AT THE ANNUAL MEETING OR NOT, YOUR SHARES CAN

MEETING.

                             ELECTION OF DIRECTORS

     The Company has three classes of directors serving staggered three-year
terms.  Class I and Class III consist of three directors each and Class II
consists of four directors.  Currently one Class I director's seat and one
Class III director's seat are vacant.  Four Class II directors are to be elected
at the Annual Meeting to serve until the 2000 Annual Meeting and until their
respective successors shall have been elected and qualified or until such
directors' earlier resignation, removal from office, death or incapacity.  The
terms of the Class III and Class I directors expire in 1998 and 1999,
respectively.

     Unless authority to vote for directors is withheld, it is intended that the
shares represented by the enclosed proxy will be voted for the election of
Kevin B. Kimberlin, Melvin Perelman, John Simon and William M. Sullivan as
Class II directors.  Messrs. Kimberlin, Perelman, Simon and Sullivan are
currently members of the Board of Directors of the Company.  Each of the
nominees has been nominated as a Class II director by the Nominating Committee
of the Company's Board of Directors.  In the event any of such nominees becomes
unable or unwilling to accept nomination or election, the shares represented by
the enclosed proxy will be voted for the election of the balance of those named
and such other nominees as the Board of Directors may select.  The Board of
Directors has no reason to believe that any such nominee will be unable or
unwilling to serve.  There are no family relationships among executive officers
or directors of the Company.

     Set forth below is information regarding the nominees for Class II director
and the continuing directors of Class III and Class I, principal occupations at
present and for the past five years, certain directorships held by each, their

     change in control.

(2)  The Company granted options representing a total of 826,405 shares of the 
     Company's Common Stock to employees in 1996.

(3)  The exercise price on the date of grant was equal to 100% of the fair 
     market value on the date of grant.

(4)  The options have a term of ten years, subject to earlier termination in 
     certain events related to termination of employment.

(5)  The fair value of each option grant was estimated on the date of grant 
     using the Black-Scholes option-pricing model with the following weighted 
     average assumptions used for grants in 1996:  risk free interest rate of 
     6.57%, expected option life of five years, expected volatility of .8472 
     and a dividend rate of zero.  Option valuation using a Black-Scholes-based 
     option-pricing model generates a theoretical value based upon certain 
     factors and assumptions.  Therefore, the value which is calculated is not 
     intended to predict future prices of the Company's Common Stock. The 
     actual value of a stock option, if any, is dependent on the future price 
     of the stock, overall stock market conditions and continued service with 
     the Company, since options remain exercisable for only a limited period 
     following retirement, death or disability. There can be no assurance that 
     the values reflected in this table or any other value will be achieved.

(6)  These options vested ratably on a daily basis over a one-year period 
     commencing on January 1, 1996.

                COMPENSATION COMMITTEE REPORT TO STOCKHOLDERS

OVERVIEW AND PHILOSOPHY

     The Compensation Committee of the Board of Directors (the "Committee") 
is composed entirely of outside directors and is responsible for developing 
and making recommendations to the Board with respect to the Company's 
executive compensation policies and practices, including the establishment of 
the annual total compensation for the chief executive officer ("CEO") and 
all executive officers.  The Committee received presentations from an outside 
compensation consultant and access to independent compensation data. The 
Board is responsible for approving and implementing the compensation 
recommendations of the Committee.  The recommendations made by the Committee 
to the Board during 1996 were approved without any significant modification.

     The Committee has developed a compensation policy which is designed to 
attract and retain qualified key executive officers critical to the Company's 
success.  In developing this policy, the Committee has concluded that it is 
not appropriate to base a significant percentage of the compensation payable 
to the executive officers upon traditional financial  targets, such as profit 
levels and return on equity.  This is primarily because the Company's 
products are still in either development or clinical testing phases, and the 
Company has not yet realized any significant revenues or product sales.  The 
Committee has based its decisions upon the following three principal 
compensation elements:

     -  Base salary levels which are commensurate with those of comparable 
positions at other biotechnology companies given the level of seniority and 
skills possessed by the executive officer which reflect the individual's 
performance with the Company over time.

     -  Annual bonuses tied to the achievement of corporate and individual 
performance objectives and the Company's stock performance.

     -  Long-term stock-based incentive awards intended to strengthen the 
mutuality of interests between the executive officers and the Company's 
stockholders.

EXECUTIVE OFFICER COMPENSATION PROGRAM COMPONENTS

     The Committee reviews the Company's compensation program to ensure that 
salary levels and incentive opportunities are competitive and reflect the 
performance of the Company. The Company's compensation program for executive 
officers consists of base salary, annual cash incentive compensation and 
long-term compensation in the form of stock options.  In addition, certain 
executive officers may also be provided supplemental long-term disability 
insurance and group term life insurance in excess of $50,000.

BASE SALARY

     Base salary levels for 1996 for the Company's executive officers were 
based on the concept of pay for performance and are competitively set 
relative to the compensation of other executives in the biotechnology 
industry at a similar stage of product development comparable to the Company 
and at other companies which compete with the Company for executive talent.  
Extensive salary survey data is available on the industry (notably, the 
annual "Biotechnology Compensation and Benefits Survey" conducted by 
Radford Associates; and Towers Perrin, a nationally recognized independent 
consulting group specializing in compensation issues) and is utilized by the 
Committee in establishing annual base salaries.  In determining base 
salaries, the Committee also considers corporate performance and progress in 
the immediately-preceding year, individual experience and performance, 
specific issues which are relevant to the Company and general economic 
conditions.  The base salary of the CEO and all other executive officers is 
reviewed annually.

                                     -12-

<PAGE>

ANNUAL INCENTIVE COMPENSATION

     Annual cash bonus payments are discretionary.  Bonus payments, if any, 
to executive officers are based on two principal factors: corporate 
performance as compared to the Company's annual goals and objectives and 
individual performance relative to corporate performance and individual goals 
and objectives.  For 1996, bonus payments were generally in recognition of 
the satisfaction of several significant corporate objectives during the year, 
including raising additional capital through the sale of Common Stock, the 
establishment of a corporate collaboration with Bayer Corporation in July 
1996, the continued clinical development of the Company's leading therapy, 
REMUNE-TM-, as well as autoimmune disease and cancer treatments, and the 
continued preclinical development of the Company's gene delivery technology.

     The achievement of corporate goals by executive officers is evaluated by 
the CEO, the results of which are submitted to the Committee for review and 
approval.  Bonus payments for the CEO are evaluated and approved by the 
Committee after its review of the CEO's achievement of corporate goals.

     Total base salary and any bonus payments are compared to "total 
compensation" as reported by the previously noted industry surveys.  Such 
total compensation for the executive officers of the Company is consistent 
with the averages of such data.

STOCK OPTION PROGRAM

     To conserve its cash resources, the Company places special emphasis on 
equity-based incentives to attract, retain and motivate executive officers as 
well as all other employees.  Under the Company's stock option plan, grants 
are priced at the fair market value on the date of grant, generally vest over 
a four year period and have a term of ten years.  Grants are made to all 
employees annually and are based on salary level and position.  All 
employees, including executive officers, are eligible for subsequent, 
discretionary grants which are generally based on either individual or 
corporate performance.  It is the Committee's intent that the best interests 
of stockholders and executives will be closely aligned and provide each 
executive officer with a significant incentive to manage the Company from the 
perspective of an owner with an equity stake in the business.  Based on 
external surveys, as mentioned above, the level of option grants to each 
executive officer in 1996 remains competitive to the level of option grants 
to officers in similar positions in the biotechnology industry.

DISCUSSION OF 1996 COMPENSATION FOR THE CHIEF EXECUTIVE OFFICER

     Dr. Dennis J. Carlo is the Company's President and Chief Executive.  
During 1996, Dr. Carlo's base salary of $341,250 was based on individual and 
corporate performance and was consistent with the updated industry data for 
base salaries of CEOs at biotechnology companies at a development stage 
comparable to the Company's.  Dr. Carlo's bonus and future salary increases, 
if any, will be based upon successful completion of corporate goals, 
including the advancement of clinical trials and recruitment of business and 
scientific collaborations.  Dr. Carlo's annual compensation is calculated to 
be commensurate with the average salaries paid by other companies in the 
biotechnology industry which are within the Radford Associates Survey, the 
Towers Perrin information, and other public and private healthcare industry 
companies with which the Company competes for personnel.

     In recognition of the satisfaction of several significant corporate 
objectives, Dr. Carlo received a stock option grant for 75,000 shares of 
Common Stock priced at the fair market value on the date of grant with a one 
year vesting period.

     Although all objectives for the Company were not met in 1996, and 
recognizing the Company's share price remained volatile, the Committee 
believes that Dr. Carlo made a significant contribution in 1996 in 
establishing a sound base for enhancing stockholder value through his 
entrepreneurial efforts.  The Committee  recognizes that the Company's 
operations resulted in a net loss and expects that losses will continue until 
one or more of the disease treatments under development is commercialized.

MISCELLANEOUS

     Section 162(m) of the Internal Revenue Code was enacted in 1993 and 
became effective in 1994.  Section 162(m) disallows the deductibility by the 
Company of any compensation over $1 million per year paid to each of the 
chief executive officer and the four other most highly compensated executive 
officers, unless certain criteria are satisfied.  In 1994, the Board of 
Director approved the amendment of the Company's 1989 Stock Plan to, among 
other things, qualify for exemption from the $1 million limit on deductions 
under Section 162(m) with respect to option grants under the 1989 Stock Plan.

                                  PROPOSAL 2

                     APPROVAL OF THE AMENDED AND RESTATED
              1989 STOCK PLAN OF THE IMMUNE RESPONSE CORPORATION

     The 1989 Stock Plan of The Immune Response Corporation was adopted by 
the Company's Board of Directors in September 1989 and subsequently approved 
by its stockholders.  In March 1997, the Board of Directors amended and 
restated the 1989 Stock Plan of The Immune Response Corporation (as amended 
and restated, the "1989 Stock Plan"), subject to approval by the Company's 
stockholders at the Annual Meeting.  The amendment and restatement of the 
1989 Stock Plan, as proposed, will be effective as of March 5, 1997, if the 
amendment described below is approved by the stockholders.

     The full text of the 1989 Stock Plan, substantially in the form in which 
it will take effect if the amendment proposed by Proposal 2 is approved by 
the stockholders, is set forth as Exhibit A to this Proxy Statement.  The 
following description of the 1989 Stock Plan is a summary only.  It is 
subject to, and qualified in its entirety by, Exhibit A.

                             SUMMARY OF AMENDMENT

     The amendment to the 1989 Stock Plan approved by the Board of Directors 
and submitted for stockholder approval is to increase the number of shares of 
Common Stock reserved for issuance under the 1989 Stock Plan by 1,000,000 
shares.

              DESCRIPTION OF AMENDED AND RESTATED 1989 STOCK PLAN

PURPOSE

     The purpose of the 1989 Stock Plan is to assist the Company in the 
recruitment, retention and motivation of employees and independent 
contractors who are in a position to make material contributions to the 
Company's progress.  The 1989 Stock Plan offers a significant incentive to 
the employees (including officers and directors who are also employees) and 
independent contractors (who are not directors) of the Company by enabling 
such employees and contractors to acquire the Company's Common Stock, thereby 
increasing their proprietary interest in the growth and success of the 
Company.

ADMINISTRATION

     The 1989 Stock Plan is administered by the Stock Option and Compensation 
Committee of the Board of Directors (the "Option Committee") composed of two 
or more disinterested members of the Board of Directors.  Subject to the 
limitations set forth in the 1989 Stock Plan, the Option Committee has the 
authority to determine to whom options will be granted and shares will be 
sold, the number of shares to be offered for sale and options to be granted, 
the price and other terms and conditions of each sale of shares and the 
exercise price and terms and conditions of each option and the type of option 
(ISO or NSO, as described below) to be granted, and to interpret the 1989 
Stock Plan and adopt rules thereunder and to make all other decisions 
relating to the operation of the 1989 Stock Plan.  The Employee Stock Option 
Committee of the Board of Directors, composed of one or more members of the 
Board of Directors who need not be disinterested, administers the 1989 Stock 
Plan with respect to employees who are not officers or directors of the 
Company.

ELIGIBILITY AND SHARES SUBJECT TO THE 1989 STOCK PLAN

     Under the 1989 Stock Plan, 5,500,000 shares of Common Stock have been 
reserved for issuance (1,000,000 shares of which are subject to stockholder 
approval at the Annual Meeting) either by direct sale or upon exercise of 
options granted to employees (including officers and directors who are also 
employees) and independent contractors of the Company who are not directors.  
The 1989 Stock Plan provides for the grant of both incentive 


                                     -16-

<PAGE>

stock options ("ISO's") intended to qualify as such under section 422 of the 
Internal Revenue Code, as amended, and nonstatutory stock options ("NSO's").  
ISO's may be granted only to employees of the Company.  NSO's may be granted, 
and Common Stock may be sold directly, to employees and independent 
contractors of the Company who are not directors.  The 1989 Stock Plan 
provides that options granted to any optionee in a single calendar year shall 
not cover more than 500,000 shares.  Such limitation has been added in 
response to recent changes in federal income tax laws and is designed to 
qualify income recognized upon exercise of options granted under the 1989 
Stock Plan for tax deductibility by the Company.  If any options granted 
under the 1989 Stock Plan shall for any reason expire or be canceled or 
otherwise terminated without having been exercised in full, the shares 
allocable to the unexercised portion of such options shall again become 
available for the 1989 Stock Plan.  If shares issued under the 1989 Stock 
Plan are forfeited, they also become available for new grants.

     As of March 31, 1997, there were 152 employees and 8 independent 
contractors eligible to participate in the 1989 Stock Plan. There have been 
529,641 options granted to such independent contractors.  As of March 31, 
1997, options to purchase an aggregate of 4,038,355 shares of Common Stock at 
an average exercise price of $4.59 per share were outstanding under the 1989 
Stock Plan.  To date, all stock options have been granted with exercise 
prices equal to the fair market value of the Company's Common Stock on the 
date of grant.  As of March 31, 1997, no shares of Common Stock have been 
issued for direct sale under the 1989 Stock Plan.  As of March 31, 1997, a 
total of 4,710,978 shares of Common Stock are reserved for future option 
grants or direct sales under the 1989 Stock Plan, (including 1,000,000 shares 
which are subject to stockholder approval at the Annual Meeting).  On March 
31, 1997, the closing price for the Company's Common Stock on the Nasdaq 
National Market was $8.38.

     As of March 31, 1997, the following persons or groups had in total, 
received options to purchase shares of Common Stock under the 1989 Stock Plan 
as follows:  (i) the Chief Executive Officer and the other executive officers 
named in the Summary Compensation Table:  Dr. Carlo, 744,650 shares, Dr. 
Brostoff, 276,116 shares, Mr. Richieri, 299,242 shares, Mr. Cashion, 258,261 
shares and Dr. Jensen, 231,325 shares; (ii) all current executive officers of 
the Company as a group:  2,033,048 shares; and (iii) all employees of the 
Company, including all current officers who are not executive officers, as a 
group:  3,508,714 shares.  Nonemployee directors are not eligible to receive 
options under the 1989 Stock Plan.

     The allocation of the additional shares of stock which the stockholders 
are being asked to approve hereby has not been determined.  Pursuant to the 
terms of the 1989 Stock Plan, the Company's Option Committee or Employee 
Stock Option Committee, as appropriate, will determine the number of options 
(and any other awards) to be allocated to employees and independent 
contractors under the 1989 Stock Plan in the future, and such allocations may 
only be made in accordance with the provisions of the 1989 Stock Plan as 
described herein.  The Company believes that the granting of options is 
necessary to attract the highest quality personnel as well as to reward and 
thereby retain existing key personnel.  Moreover, the attraction and 
retention of such personnel is essential to the continued progress of the 
Company which ultimately is in the interests of the Company's stockholders.  
The amendment to increase the number of shares under the 1989 Stock Plan will 
not result in any new plan benefits to the Company's nonemployee directors.

TERMS OF OPTIONS

     Options granted pursuant to the 1989 Stock Plan will vest at the time or 
times determined by the Option Committee.

     The maximum term of each option granted under the 1989 Stock Plan is 10 
years (5 years in the case of an ISO granted to a 10% stockholder).  Stock 
options granted under the 1989 Stock Plan must be exercised by the optionee 
during the earlier of the term of such option or within 90 days after 
termination of the optionee's employment, except that the period may be 
extended on certain events including death and termination of employment due 
to disability.

     The exercise price of shares of Common Stock subject to options 
qualifying as ISO's must not be less than 100% (110% in the case of an ISO 
granted to a 10% stockholder) of the fair market value of the Common 


                                     -17-

<PAGE>

Stock on the date of the grant.  The exercise price of NSO's granted under 
the 1989 Stock Plan must not be less than 85% of the fair market value of the 
Common Stock on the date of grant.  Under the 1989 Stock Plan, the exercise 
price is payable in cash, Common Stock or by full-recourse promissory note.  
The 1989 Stock Plan also permits an optionee to pay the exercise price of an 
option by delivery (on a form prescribed by the Company) of an irrevocable 
direction to a securities broker approved by the Company to sell the 
optionee's shares and deliver all or a part of the sale proceeds to the 
Company in payment of all or part of the exercise price and any withholding 
taxes or by delivery of an irrevocable direction to pledge the optionee's 
shares to a securities broker or lender approved by the Company as security 
for a loan and to deliver all or part of the loan proceeds to the Company in 
payment of all or part of the exercise price and any withholding taxes.

TERMS OF SHARES OFFERED FOR SALE

     The terms of any sale of shares of Common Stock under the 1989 Stock 
Plan will be set forth in a common stock purchase agreement to be entered 
into between the Company and each purchaser.  The terms of the stock purchase 
agreements entered into under the 1989 Stock Plan need not be identical, and 
the Option Committee shall determine all terms and conditions of each such 
agreement, which shall be consistent with the 1989 Stock Plan.  The purchase 
price for shares sold under the 1989 Stock Plan shall not be less than 85% of 
the fair market value of such shares.  The purchase price may be paid, at the 
Option Committee's discretion, with a full-recourse promissory note secured 
by the shares, except that the par value of the shares must be paid in cash.  
Shares may also be awarded under the 1989 Stock Plan in consideration of 
services rendered prior to the award, without a cash payment by the recipient.

     Shares sold under the 1989 Stock Plan will vest upon satisfaction of the 
conditions specified in the stock purchase agreement. Vesting conditions are 
determined by the Option Committee and may be based on the recipient's 
service, individual performance, the Company's performance or such other 
criteria as the Option Committee may adopt.  Shares may be subject to 
repurchase by the Company at their original purchase price in the event that 
any applicable vesting conditions are not satisfied.  Shares sold under the 
1989 Stock Plan may not be resold or otherwise transferred until they have 
vested, except that certain transfers to a trust may be permitted.  Any right 
to acquire shares under the 1989 Stock Plan (other than an option) will 
automatically expire if not exercised within 30 days after the grant if such 
right was communicated by the Option Committee.  A holder of shares sold 
under the 1989 Stock Plan has the same voting, dividend and other rights as 
the Company's other stockholders.

DURATION, AMENDMENT AND TERMINATION

     The Board of Directors may amend, suspend or terminate the 1989 Stock 
Plan at any time, except that any such amendment, suspension or termination 
shall not affect any option previously granted.  Any amendment of the 1989 
Stock Plan, however, which increases the number of shares available for 
issuance, materially changes the class of persons who are eligible for the 
grant of ISO's or, if required by Rule 16b-3 (or any successor) under the 
Securities Exchange Act of 1934, as amended, would materially increase the 
benefits accruing to participants under the 1989 Stock Plan or would 
materially modify the requirement as to eligibility for participation in the 
1989 Stock Plan, is subject to approval of the Company's stockholders.  
Stockholder approval is not required for any other amendment of the 1989 
Stock Plan.  Unless sooner terminated by the Board of Directors, the 1989 
Stock Plan will terminate in March 2007, and no further options may be 
granted or stock sold pursuant to such plan following the termination date.

EFFECT OF CERTAIN CORPORATE EVENTS

     Outstanding employee stock option agreements entered into pursuant to 
the 1989 Stock Plan provide for the automatic vesting of employee stock 
options and (in the case of the common stock purchase agreements) the 
automatic termination of the Company's right of repurchase upon a change of 
control.  Future employee stock option agreements and common stock purchase 
agreements entered into pursuant to the 1989 Stock Plan will contain similar 
provisions, unless otherwise determined by the Option Committee.

     For purposes of the 1989 Stock Plan, the term "change in control" means 
(1) that a change in the composition of the Board of Directors occurs as a 
result of which fewer than two-thirds of the incumbent directors are 
directors (the "Continuing Directors") who either had been directors of the 
Company 24 months prior to such change or were elected or nominated for 
election to the Board of Directors with the approval of at least a majority 
of the directors who had been directors of the Company 24 months prior to 
such change and who were still in office at the time of the election or 
nomination, (2) that any person is or becomes the beneficial owner, directly 
or indirectly, of at least 25% of the combined voting power of the Company's 
outstanding securities and such ownership has not been approved by a majority 
of the Continuing Directors who had been directors of the Company 24 months 
prior to the acquisition or aggregation and who were still in office at the 
time of such acquisition or aggregation, or (3) that any person is or becomes 
the beneficial owner, directly or indirectly, of at least 50% of the combined 
voting power of the Company's outstanding securities.  A change in the 
relative beneficial ownership under (2) or (3) above by reason of a 
repurchase by the Company of its own securities will be disregarded.

     In the event of a subdivision of the outstanding Common Stock, a 
combination or consolidation of the outstanding Common Stock (by 
reclassification or otherwise) into a lesser number of shares, a declaration 
of a dividend payable in Common Stock or in a form other than Common Stock in 
an amount that has a material effect on the price of the shares, or a similar 
occurrence, the Option Committee will make adjustments in the number and/or 
exercise price of options and/or the number of shares available under the 
1989 Stock Plan, as appropriate.

     In the event of a merger or other reorganization, outstanding options 
will be subject to the agreement of merger or reorganization.  Such agreement 
will provide for the assumption of outstanding options by the surviving 
corporation or its parent, for their continuation by the Company (if the 
Company is the surviving corporation), for payment of a cash settlement equal 
to the difference between the amount to be paid for one share under the 
agreement of merger or reorganization and the exercise price for each option, 
or for the acceleration of the exercisability of each option followed by the 
cancellation of options not exercised, in all cases without the optionee's 
consent.

FEDERAL INCOME TAX CONSEQUENCES OF OPTIONS UNDER THE 1989 STOCK PLAN

     Neither the optionee nor the Company will incur any federal tax 
consequences as a result of the grant of an option.  The optionee will have 
no taxable income upon exercising an ISO (except that the alternative minimum 
tax may apply), and the Company will receive no deduction when an ISO is 
exercised.  Upon exercising an NSO, the optionee generally must recognize 
ordinary income equal to the "spread" between the exercise price and the fair 
market value of Common Stock on the date of exercise; the Company generally 
will be entitled to a deduction for the same amount.  In the case of an 
employee, the option spread at the time an NSO is exercised is subject to 
income tax withholding, but the optionee generally may elect to satisfy the 
withholding tax obligation by having shares of Common Stock withheld from 
those purchased under the NSO.  The tax treatment of a disposition of option 
shares acquired under the 1989 Stock Plan depends on how long the shares have 
been held and on whether such shares were acquired by exercising an ISO or by 
exercising an NSO.  The Company will not be entitled to a deduction in 
connection with a disposition of option shares, except in the case of a 
disposition of shares acquired under an ISO before the applicable ISO holding 
periods have been satisfied.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 2.

                                  PROPOSAL 3

                     RATIFICATION OF INDEPENDENT AUDITORS

     Upon the recommendation of the Audit Committee, the Board of Directors 
has appointed the firm of Arthur Andersen LLP as the Company's independent 
auditors for the fiscal year ended December 31, 1997, subject to ratification 
by the stockholders. Representatives of Arthur Andersen LLP are expected to 
be present at the 


                                     -19-

<PAGE>

Company's Annual Meeting.  They will have an opportunity to make a statement, 
if they desire to do so, and will be available to respond to appropriate 
questions.

     Effective December 16, 1996, Arthur Andersen LLP was engaged as 
principal independent accountants for the Company. Ernst & Young LLP ("E & 
Y"), dismissed effective December 16, 1996, had been the independent 
accountants of the Company. The decision to change independent accountants 
was approved by the Audit Committee of the Company's Board of Directors. 
During the Company's two most recent fiscal years and subsequent interim 
periods, there were no disagreements with E & Y on any matter of accounting 
principles or practices, financial statement disclosure, or auditing scope or 
procedures, which disagreements if not resolved to E & Y's satisfaction would 
have caused them to make reference to the matter in their report. The audit 
reports of E & Y on the financial statements of the Company for the past two 
fiscal years did not contain any adverse opinion or disclaimer of opinion, 
nor were they qualified or modified as to audit scope or accounting 
principles. During the Company's two most recent fiscal years and subsequent 
interim periods, there have been no reportable events. During the two most 
recent fiscal years and subsequent interim periods, the Company had not 
consulted with Arthur Andersen LLP on items which involved either the 
Company's accounting principles or the form of audit opinion or concerned the 
subject matter of a disagreement or reportable event with the former auditor. 

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 3.

                            STOCKHOLDER PROPOSALS

proposal must be received at the offices of the Company, 5935 Darwin Court, 
Carlsbad, California 92008, not later than December 19, 1997.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Under Section 16(a) under the Securities and Exchange Act of 1934, as 
amended, the Company's directors, executive officers and any persons holding 
more than 10% of the Company's Common Stock are required to report their 
initial ownership of the Company's Common Stock and any subsequent changes in 
that ownership to the Securities and Exchange Commission.  Specific due dates 
for these reports have been established and the Company is required to 
identify in this Proxy Statement those persons who failed to timely file 
these reports.  All of the filing requirements were satisfied in 1996.  In 
making this disclosure, the Company has relied solely on written 
representations of its directors and executive officers and copies of the 
reports that have been filed with the Commission.

                                 OTHER MATTERS

     The Board of Directors knows of no other business that will be presented 
at the Annual Meeting.  If any other business is properly brought before the

     Whether you intend to be present at the Annual Meeting or not, we urge

          (i)    To interpret the Plan and to apply its provisions;

      or other right under the Plan and to determine the sufficiency of such 
      consideration; and

                                       A-3

      the administration of the Plan.

All decisions, interpretations and other actions of the Committee shall be 
final and binding on all Offerees, all Optionees, and all persons deriving 
their rights from an Offeree or Optionee.  No member of the Committee shall 
be liable for any action that he or she has taken or has failed to take in 
good faith with respect to the Plan, any Option, or any right to acquire 
Shares under the Plan.

SECTION 4.  ELIGIBILITY.

     (a)  GENERAL RULE.  Only Employees shall be eligible for designation as 
Optionees or Offerees by the Committee.  In addition, only individuals who 
are employed as common-law employees by the Company or a Subsidiary shall be 
eligible for the grant of ISOs.

     (b)  TEN-PERCENT STOCKHOLDERS.  An Employee who owns more than 10 
percent of the total combined voting power of all classes of outstanding 
stock of the Company or any of its Subsidiaries shall not be eligible for the 
grant of an ISO unless (i) the Exercise Price is at least 110 percent of the 
Fair Market Value of a Share on the date of grant and (ii) such ISO by its 
terms is not exercisable after the expiration of five years from the date of 
grant.

     (c)  ATTRIBUTION RULES.  For purposes of Subsection (b) above, in 
determining stock ownership, an Employee shall be deemed to own the stock 
owned, directly or indirectly, by or for his or her brothers, sisters, 
spouse, ancestors and lineal descendants. Stock owned, directly or 
indirectly, by or for a corporation, partnership, estate or trust shall be 
deemed to be owned proportionately by or for its shareholders, partners or 
beneficiaries.  Stock with respect to which such Employee holds an option 
shall not be counted.

     (d)  OUTSTANDING STOCK.  For purposes of Subsection (b) above, 
"outstanding stock" shall include all stock actually issued and outstanding 
immediately after the grant.  "Outstanding stock" shall not include shares 
authorized for issuance under outstanding options held by the Employee or by 
any other person.

SECTION 5.  STOCK SUBJECT TO PLAN.

     (a)  BASIC LIMITATION.  Shares offered under the Plan shall be 
authorized but unissued Shares or treasury Shares.  The aggregate number of 
Shares which may be issued under the Plan (upon exercise of Options or other 
rights to acquire Shares) shall not exceed 5,500,000 Shares, subject to 
adjustment pursuant to Section 9.  The number of Shares which are subject to 
Options or other rights outstanding at any time under the Plan shall not 
exceed the number of Shares which then remain available for issuance under 
the Plan.  The Company, during the term of the Plan, shall at all times 
reserve and keep available sufficient Shares to satisfy the requirements of 
the Plan.

     (b)  ADDITIONAL SHARES.  In the event that any outstanding Option or 
other right for any reason expires or is canceled or otherwise terminated, 
the Shares allocable to the unexercised portion of such Option or other right 
shall again be available for the purposes of the Plan.  In the event that 
Shares issued under the Plan are reacquired by the Company pursuant to a 
forfeiture provision, a right of repurchase or a right of first refusal, such 
Shares shall again be available for the purposes of the Plan.

SECTION 6.  TERMS AND CONDITIONS OF AWARDS OR SALES.

     (a)  STOCK PURCHASE AGREEMENT.  Each award or sale of Shares under the 
Plan (other than upon exercise of an Option) shall be evidenced by a Stock 
Purchase Agreement between the Offeree and the Company.  Such award or sale 
shall be subject to all applicable terms and conditions of the Plan and may 
be subject to any other terms and conditions which are not inconsistent with 
the Plan and which the Committee deems appropriate for inclusion in a Stock 
Purchase Agreement.  The provisions of the various Stock Purchase Agreements 
entered into under the Plan need not be identical.

                                       A-4

<PAGE>


     (b)  DURATION OF OFFERS AND NONTRANSFERABILITY OF RIGHTS.  Any right to 
acquire Shares under the Plan (other than an Option) shall automatically 
expire if not exercised by the Offeree within thirty (30) days after the 
grant of such right was communicated to him or her by the Committee.  Such 
right shall not be transferable and shall be exercisable only by the Offeree 
to whom such right was granted.

     (c)  PURCHASE PRICE.  The Purchase Price of Shares to be offered under 
the Plan shall not be less than 85 percent of the Fair Market Value of such 
Shares.  Subject to the preceding sentence, the Purchase Price shall be 
determined by the Committee at its sole discretion.  The Purchase Price shall 
be payable in a form described in Section 8.

     (d)  WITHHOLDING TAXES.  As a condition to the purchase of Shares, the 
Offeree shall make such arrangements as the Committee may require for the 
satisfaction of any federal, state, local or foreign withholding tax 
obligations that may arise in connection with such purchase.

     (e)  RESTRICTIONS ON TRANSFER OF SHARES.  Any Shares awarded or sold 
under the Plan shall be subject to such special forfeiture conditions, rights 
of repurchase, rights of first refusal and other transfer restrictions as the 
Committee may determine.  Such restrictions shall be set forth in the 
applicable Stock Purchase Agreement and shall apply in addition to any 
general restrictions that may apply to all holders of Shares.

SECTION 7.  TERMS AND CONDITIONS OF OPTIONS.

     (a)  STOCK OPTION AGREEMENT.  Each grant of an Option under the Plan 
shall be evidenced by a Stock Option Agreement between the Optionee and the 
Company.  Such Option shall be subject to all applicable terms and conditions 
of the Plan and may be subject to any other terms and conditions which are 
not inconsistent with the Plan and which the Committee deems appropriate for 
inclusion in a Stock Option Agreement.  The provisions of the various Stock 
Option Agreements entered into under the Plan need not be identical.

     (b)  NUMBER OF SHARES.  Each Stock Option Agreement shall specify the 
number of Shares that are subject to the Option and shall provide for the 
adjustment of such number in accordance with Section 9.  Options granted to 
any Optionee in a single calendar year shall in no event cover more than 
500,000 Shares, subject to adjustment in accordance with Section 9.  The 
Stock Option Agreement shall also specify whether the Option is an ISO or a 
Nonstatutory Option.

     (c)  EXERCISE PRICE.  Each Stock Option Agreement shall specify the 
Exercise Price.  The Exercise Price of an ISO shall not be less than 100 
percent of the Fair Market Value of a Share on the date of grant, except as 
otherwise provided in Section 4(b).  The Exercise Price of a Nonstatutory 
Option shall not be less than 85 percent of the Fair Market Value of a Share 
on the date of grant. Subject to the preceding two sentences, the Exercise 
Price under any Option shall be determined by the Committee at its sole 
discretion.  The Exercise Price shall be payable in a form described in 
Section 8.

     (d)  WITHHOLDING TAXES.  As a condition to the exercise of an Option, 
the Optionee shall make such arrangements as the Committee may require for 
the satisfaction of any federal, state, local or foreign withholding tax 
obligations that may arise in connection with such exercise.  The Optionee 
shall also make such arrangements as the Committee may require for the 
satisfaction of any federal, state, local or foreign withholding tax 
obligations that may arise in connection with the disposition of Shares 
acquired by exercising an Option.

     (e)  EXERCISABILITY AND TERM.  Each Stock Option Agreement shall specify 
the date when all or any installment of the Option is to become exercisable.  
The vesting of any Option shall be determined by the Committee at its sole 
discretion.  A Stock Option Agreement may provide for accelerated 
exercisability in the event of the Optionee's death, Total and Permanent 
Disability, retirement or other events.  The Stock Option Agreement shall 
also specify the term of the Option.  The term shall not exceed 10 years from 
the date of grant, except as otherwise provided in Section 4(b).  Subject to 
the preceding sentence, the Committee at its sole discretion shall determine 
when an Option is to expire.

                                       A-5
<PAGE>

     (f)  NONTRANSFERABILITY.  During an Optionee's lifetime, his or her 
Option(s) shall be exercisable only by him or her and shall not be 
transferable.  In the event of an Optionee's death, his or her Option(s) 
shall not be transferable other than by will, by a beneficiary designation 
executed by the Optionee and delivered to the Company, or by the laws of 
descent and distribution.

     (g)  TERMINATION OF SERVICE (EXCEPT BY DEATH).  If an Optionee's Service 
terminates for any reason other than his or her death, then his or her 
Option(s) shall expire on the earliest of the following occasions:

          (i)  The expiration date determined pursuant to Subsection (e) 
     above;

          (ii)  The date 90 days after the termination of his or her Service 
     for any reason other than Total and Permanent Disability; or

          (iii)  The date six months after the termination of his or her 
     Service by reason of Total and Permanent Disability.

The Optionee may exercise all or part of his or her Option(s) at any time 
before the expiration of such Option(s) under the preceding sentence, but 
only to the extent that such Option(s) had become exercisable before his or 
her Service terminated or became exercisable as a result of the termination.  
The balance of such Option(s) shall lapse when the Optionee's Service 
terminates.  In the event that the Optionee dies after the termination of his 
or her Service but before the expiration of his or her Option(s), all or part 
of such Option(s) may be exercised (prior to expiration) by the executors or 
administrators of the Optionee's estate or by any person who has acquired 
such Option(s) directly from him or her by bequest, beneficiary designation 
or inheritance, but only to the extent that such Option(s) had become 
exercisable before his or her Service terminated or became exercisable as a 
result of the termination.

     (h)  LEAVES OF ABSENCE.  For purposes of Subsection (g) above, Service 
shall be deemed to continue while the Optionee is on military leave, sick 
leave or other bona fide leave of absence (as determined by the Committee).  
The foregoing notwithstanding, in the case of an ISO granted under the Plan, 
Service shall not be deemed to continue beyond the first 90 days of such 
leave, unless the Optionee's reemployment rights are guaranteed by statute or 
by contract.

     (i)  DEATH OF OPTIONEE.  If an Optionee dies while he or she is in 
Service, then his or her Option(s) shall expire on the earlier of the 
following dates:

          (i)  The expiration date determined pursuant to Subsection (e) 
     above; or

          (ii)  The date six months after his or her death.

All or part of the Optionee's Option(s) may be exercised at any time before 
the expiration of such Option(s) under the preceding sentence by the 
executors or administrators of his or her estate or by any person who has 
acquired such Option(s) directly from him or her by bequest, beneficiary 
designation or inheritance, but only to the extent that such Option(s) had 
become exercisable before his or her death or became exercisable as a result 
of his or her death.  The balance of such Option(s) shall lapse when the 
Optionee dies.

     (j)  NO RIGHTS AS A STOCKHOLDER.  An Optionee, or a transferee of an 
Optionee, shall have no rights as a stockholder with respect to any Shares 
covered by his or her Option until the date of the issuance of a stock 
certificate for such Shares.  No adjustments shall be made, except as 
provided in Section 9.

     (k)  MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS.  Within the 
limitations of the Plan, the Committee may modify, extend or renew 
outstanding Options or may accept the cancellation of outstanding Options (to 
the extent not previously exercised) in return for the grant of new Options 
at the same or a different price.  The foregoing notwithstanding, no 
modification of an Option shall, without the consent of the Optionee, impair 
his or her rights or increase his or her obligations under such Option.


                                      A-6

     (l)  RESTRICTIONS ON TRANSFER OF SHARES.  Any Shares issued upon 
exercise of an Option shall be subject to such special forfeiture conditions, 
rights of repurchase, rights of first refusal and other transfer restrictions 
as the Committee may determine. Such restrictions shall be set forth in the 
applicable Stock Option Agreement and shall apply in addition to any general 
restrictions that may apply to all holders of Shares.

SECTION 8.  PAYMENT FOR SHARES.

     (a)  GENERAL RULE.  The entire Purchase Price or Exercise Price of 
Shares issued under the Plan shall be payable in lawful money of the United 
States of America at the time when such Shares are purchased, except as 
follows:

          (i)  In the case of Shares sold under the terms of a Stock Purchase 
     Agreement subject to the Plan, payment shall be made only pursuant to 
     the express provisions of such Stock Purchase Agreement.  However, the 
     Committee (at its sole discretion) may specify in the Stock Purchase 
     Agreement that payment may be made in one or both of the forms described in
     Subsections (e) and (f) below.

          (ii)  In the case of an ISO granted under the Plan, payment shall 
     be made only pursuant to the express provisions of the applicable Stock 
     Option Agreement.  However, the Committee (at its sole discretion) may 
     specify in the Stock Option Agreement that payment may be made pursuant 
     to Subsections (b), (c), (d) or (f) below.

          (iii)  In the case of a Nonstatutory Option granted under the Plan, 
     the Committee (at its sole discretion) may accept payment in one or more 
     of the forms described in Subsections (b), (c), (d) or (f) below.

     (b)  SURRENDER OF STOCK.  To the extent that this Subsection (b) is 
applicable, payment may be made all or in part with Shares which have already 
been owned by the Optionee or his or her representative for more than 12 
months and which are surrendered to the Company in good form for transfer.  
Such Shares shall be valued at their Fair Market Value on the date when the 
new Shares are purchased under the Plan.

     (c)  EXERCISE/SALE.  To the extent that this Subsection (c) is 
applicable, payment may be made by the delivery (on a form prescribed by the 
Company) of an irrevocable direction to a securities broker approved by the 
Company to sell Common Shares and to deliver all or part of the sales 
proceeds to the Company in payment of all or part of the Exercise Price and 
any withholding taxes.

     (d)  EXERCISE/PLEDGE.  To the extent that this Subsection (d) is 
applicable, payment may be made by the delivery (on a form prescribed by the 
Company) of an irrevocable direction to pledge Common Shares to a securities 
broker or lender approved by the Company, as security for a loan and to 
deliver all or part of the loan proceeds to the Company in payment of all or 
part of the Exercise Price and any withholding taxes.

     (e)  SERVICES RENDERED.  To the extent that this Subsection (e) is 
applicable, Shares may be awarded under the Plan in consideration of services 
rendered to the Company or a Subsidiary prior to the award.  If Shares are 
awarded without the payment of a Purchase Price in cash, the Committee shall 
make a determination (at the time of the award) of the value of the services 
rendered by the Offeree and the sufficiency of the consideration to meet the 
requirements of Section 6(c).

     (f)  PROMISSORY NOTE.  To the extent that this Subsection (f) is 
applicable, a portion of the Purchase Price or Exercise Price, as the case 
may be, of Shares issued under the Plan may be payable by a full-recourse 
promissory note, provided that (i) the par value of such Shares must be paid 
in lawful money of the United States of America at the time when such Shares 
are purchased, (ii) the Shares are security for payment of the principal 
amount of the promissory note and interest thereon, and (iii) the interest 
rate payable under the terms of the promissory note shall be no less than the 
minimum rate (if any) required to avoid the imputation of additional 


                                      A-7

<PAGE>

interest under the Code.  Subject to the foregoing, the Committee (at its 
sole discretion) shall specify the term, interest rate, amortization 
requirements (if any), and other provisions of such note.

SECTION 9.  ADJUSTMENT OF SHARES.

     (a)  GENERAL.  In the event of a subdivision of the outstanding Stock, a 
declaration of a dividend payable in Shares, a declaration of a dividend 
payable in a form other than Shares in an amount that has a material effect 
on the value of Shares, a combination or consolidation of the outstanding 
Stock (by reclassification or otherwise) into a lesser number of Shares, a 
recapitalization or a similar occurrence, the Committee shall make 
appropriate adjustments in one or more of (i) the number of Shares available 
for future grants under Section 5, (ii) the limit set forth in Section 7(b), 
(ii) the number of Shares covered by each outstanding Option or (iii) the 
Exercise Price under each outstanding Option.

     (b)  REORGANIZATIONS.  In the event that the Company is a party to a 
merger or other reorganization, outstanding Options shall be subject to the 
agreement of merger or reorganization.  Such agreement shall provide for the 
assumption of outstanding Options by the surviving corporation or its parent, 
for their continuation by the Company (if the Company is a surviving 
corporation), for payment of a cash settlement equal to the difference 
between the amount to be paid for one Share under such agreement and the 
Exercise Price, or for the acceleration of their exercisability followed by 
the cancellation of Options not exercised, in all cases without the 
Optionees' consent.  Any cancellation shall not occur earlier than 30 days 
after such acceleration is effective and Optionees have been notified of such 
acceleration.  In the case of Options that have been outstanding for less 
than 12 months, a cancellation need not be preceded by an acceleration.

     (c)  RESERVATION OF RIGHTS.  Except as provided in this Section 9, an 
Optionee or Offeree shall have no rights by reason of any subdivision or 
consolidation of shares of stock of any class, the payment of any dividend or 
any other increase or decrease in the number of shares of stock of any class. 
 Any issue by the Company of shares of stock of any class, or securities 
convertible into shares of stock of any class, shall not affect, and no 
adjustment by reason thereof shall be made with respect to, the number or 
Exercise Price of Shares subject to an Option.  The grant of an Option 
pursuant to the Plan shall not affect in any way the right or power of the 
Company to make adjustments, reclassifications, reorganizations or changes of 
its capital or business structure, to merge or consolidate or to dissolve, 
liquidate, sell or transfer all or any part of its business or assets.

SECTION 10.  SECURITIES LAWS.

     Shares shall not be issued under the Plan unless the issuance and 
delivery of such Shares complies with (or is exempt from) all applicable 
requirements of law, including (without limitation) the Securities Act of 
1933, as amended, the rules and regulations promulgated thereunder, state 
securities laws and regulations, and the regulations of any stock exchange on 
which the Company's securities may then be listed.

SECTION 11.  NO EMPLOYMENT RIGHTS.

     No provision of the Plan, nor any right or Option granted under the 
Plan, shall be construed to give any person any right to become, to be 
treated as, or to remain an Employee.  The Company and its Subsidiaries 
reserve the right to terminate any person's Service at any time and for any 
reason.

SECTION 12.  DURATION AND AMENDMENTS.

     (a)  TERM OF THE PLAN.  The Plan, as set forth herein, shall become 
effective on March 5, 1997, the date the Board of Directors amended and 
restated the Plan, subject to the approval of the Company's stockholders.  In 
the event that the stockholders fail to approve the amendment and restatement 
of the Plan at the 1997 annual meeting, any Option grants or Stock awards 
made in excess of an aggregate of 5,500,000 Shares shall be null and void.   
The Plan shall terminate automatically on March 5, 2007, and may be 
terminated on any earlier date pursuant to Subsection (b) below.


                                      A-8

<PAGE>

     (b)  RIGHT TO AMEND OR TERMINATE THE PLAN.  The Board of Directors may 
amend, suspend or terminate the Plan at any time and for any reason; 
provided, however, that any amendment of the Plan which (i) increases the 
number of Shares available for issuance under the Plan (except as provided in 
Section 9), (ii) materially changes the class of persons who are eligible for 
the grant of ISOs or (iii) if required by Rule 16b-3 (or any successor) under 
the Exchange Act, would materially increase the benefits accruing to 
participants under the Plan or would materially modify the requirements as to 
eligibility for participation in the Plan, shall be subject to the approval 
of the Company's stockholders.  Stockholder approval shall not be required 
for any other amendment of the Plan.

     (c)  EFFECT OF AMENDMENT OR TERMINATION.  No Shares shall be issued or 
sold under the Plan after the termination thereof, except upon exercise of an 
Option granted prior to such termination.  The termination of the Plan, or 
any amendment thereof, shall not affect any Share previously issued or any 
Option previously granted under the Plan.

SECTION 13.  EXECUTION.

     To record the amendment and restatement of the Plan by the Board of 
Directors on March 5, 1997, the Company has caused its authorized officer to 
execute the same.
