                        PROXY STATEMENT
                         ____________


TO THE STOCKHOLDERS:

          The enclosed proxy is solicited on behalf of the
Board of Directors of XOMA Corporation, a Delaware corporation
("XOMA" or the "Company"), for use at the annual meeting of
stockholders to be held at The Claremont Hotel, Ashby and
Domingo Avenues, Berkeley, California 94623, on June 13, 1996,
at 9:00 a.m. local time, or any adjournment or postponement
thereof, at which stockholders of record on April 24, 1996 will
be entitled to vote.  On April 24, 1996, the Company had issued
and outstanding 31,581,420 shares of its common stock, par
value $.0005 per share ("Common Stock").

          Holders of Common Stock are entitled to one vote for
each share held.

          Any person giving a proxy in the form accompanying
this proxy statement has the power to revoke it at any time
before its exercise.  It may be revoked by filing with the
Secretary of the Company at the Company's principal office,
2910 Seventh Street, Berkeley, California 94710, an instrument
of revocation or a duly executed proxy bearing a later date, or
it may be revoked by attending the meeting and voting in
person.  Abstentions and broker non-votes are each included in
the number of shares present and voting for purposes of
establishing a quorum.  Each is tabulated separately.
Abstentions are counted in tabulations of the votes cast on
proposals presented to stockholders, whereas broker non-votes
are not counted for purposes of determining whether a proposal
has been approved.

          The Company will bear the entire cost of
solicitation, including preparation, assembly, printing, and
mailing of this proxy statement, the proxy card, and any
additional material furnished to stockholders.  Copies of
solicitation material will be furnished to brokerage houses,
fiduciaries, and custodians holding in their names shares that
are beneficially owned by others to forward to such beneficial
owners.  The Company has retained the services of Skinner & Co.
to aid in the solicitation of proxies from brokers, bank
nominees and other institutional owners.  The Company estimates
that it will pay 

     

                              -2-



Skinner & Co. a fee not to exceed $4,000 for its services
and will reimburse Skinner & Co. for certain out-of-pocket
expenses estimated to be not more than $6,000.  In
addition, the solicitation of proxies may be supplemented by
one or more of telephone, telegram, or personal solicitation by
directors, officers, or employees of the Company for no
additional compensation.  Except as described above, the
Company does not intend to solicit proxies other than by mail.

          The Company intends to mail this proxy statement on
or about April 30, 1996.

(1)   The amounts set forth in the three columns represent hypothetical gains that might be achieved by
      the optionees if the respective options are exercised at the end of their ten-year option terms.
      These gains are based on assumed rates of stock price appreciation of 0%, 5% and 10% compounded
      annually from the dates the respective options were granted.  The 0% appreciation column is
      included because the options were granted with exercise prices equal to the market price of the
      underlying Common Stock on the date of grant, and thus will have no value unless the Company's
      stock price increases above the exercise prices as a result of actions by the executives that
      improve the Company's performance and/or other factors affecting such price.

Employment Contracts and Termination of Employment
and Change-in-Control Arrangements

          The Company has entered into an employment agreement
with Mr. Castello, dated as of April 29, 1992, that provides
for his employment as President and Chief Executive Officer at
a salary of $500,000 per year.  Under this agreement,
Mr. Castello also receives all standard Company employee
benefits and supplemental life insurance for the amount that
an annual premium of $18,000 provides.  The agreement also
provides for a grant of options for 500,000 shares of Common
Stock under the Company's 1981 Stock Option Plan, which was
made in 1992.  Mr. Castello was also reimbursed under the
agreement for expenses related to his relocation to the San
Francisco Bay area.  See footnote (2) under the "Summary
Compensation Table" above.

          Mr. Castello's employment may be terminated, with or
without cause, at the will of either party.  If terminated by
the Company for any reason other than due cause or by Mr.
Castello for good reason, Mr. Castello must be paid his then
current base salary and benefits for one year.  If terminated
for due cause, he is entitled to no further compensation.
Good reason includes, in the context of a change of control,
the assignment to Mr. Castello of duties inconsistent with his
prior duties; his removal from, or failure to re-elect him to,
any position he held immediately prior to the change in
control; any termination by the Company within three years of
the change of control other than for due cause or upon
disability or death; a good faith determination by Mr.
Castello that changes in circumstances resulting from the
change in control leave him substantially unable to perform
his duties, after notice; the failure of the Company's
successor or the transferee of its assets or business to
assume its obligations under the agreement; or, a significant
relocation of the Company's executive offices.  Good reason
also includes any reduction in base pay or benefits or any
breach of the agreement by the Company.

          The Company has entered into an employment agreement
with Dr. Scannon, dated as of March 29, 1993, that provides
for his employment as Chief Scientific and Medical Officer at
a salary of $300,000 per year.  Under this agreement, Dr.
Scannon is entitled to participate in any benefit plan for
which key executives of the Company are eligible.  In
addition, the agreement provides for a grant of options for
50,000 shares of Common Stock under the Company's 1981 Stock Option

     

                             -13-



Plan, which was made in 1993.  The agreement also provides
that Dr. Scannon is entitled to participate in the
Management Incentive Compensation Plan, and Dr. Scannon
received $8,214 and 1,094 shares of stock in 1994 and $8,214
in 1995 (relating to performance in 1993) under the provisions
of such plan.  The agreement also provides for a one-year loan
to Dr. Scannon in the amount of $290,000, bearing interest at
6% per annum and secured by a pledge of certain shares of the
Company's Common Stock.  The loan was made to Dr. Scannon in
1993, has been extended for three additional years, and
$50,000 in principal and interest payments have been received
by the Company to date.  The loan will become payable on
demand in the event of any early termination of Dr. Scannon's
employment.  Upon termination of his employment for any reason
other than cause, or upon resignation, Dr. Scannon must be
paid his then current base salary and benefits for one year.

          The Company has entered into an employment agreement
with Mr. Davis dated as of April 1, 1994 that provides for his
employment as Chief Financial Officer at a salary of $200,000
per year.  Under this agreement, Mr. Davis received a one-time
transition allowance in the amount of $35,000 (repayable on a
pro rata basis if employment was terminated within 18 months)
and is entitled to participate in any benefit plan for which
executives of the Company are eligible.  In addition, the
agreement provides for a grant of options for 60,000 shares of
Common Stock under the Company's 1981 Stock Option Plan, which
was made in 1994, as well as participation in the Management
Incentive Compensation Plan and the payment of Mr. Davis'
relocation expenses.  See footnote (2) under the "Summary
Compensation Table" above.  Mr. Davis' employment agreement
provides no additional compensation in the event of a change
of control but provides a minimum severance amount equal to
six months of base salary at the time of termination.

          The Company entered into an employment agreement
with Mr. Mendell, dated as of April 29, 1992, that provided
for his employment as Chairman of the Board, devoting at least
80% of his time to the Company, at a minimum salary of
$300,000 per year.  Under this agreement, Mr. Mendell was
entitled to participate in any benefit plan for which key
executives of the Company are eligible.  In addition, the
agreement provided for a one-time special award consisting of
a cash payment of $125,000 and an option grant for 100,000
shares of Common Stock under the Company's 1981 Stock Option
Plan (the "Special Award Option").  In March 1993, Mr. Mendell
and the Company agreed to a modification of his employment


     

                             -14-



agreement replacing his Special Award Option with a new option
grant for 50,000 shares of Common Stock exercisable
immediately.  Mr. Mendell resigned as Chairman of the Board in
March 1993 and as an employee in June 1993.  His agreement
provided that, in such event, Mr. Mendell would receive the
principal economic benefits of his contract for two years.
Pursuant to these provisions, Mr. Mendell received payments
totalling $175,000 in 1993, $300,000 in 1994 and $125,000 in
1995, whereupon the Company's obligations thereunder ceased. 

Compensation Committee Report on Executive Compensation

          The Company's compensation program for officers
(including the named executive officers) is administered by
the Compensation Committee of the Board of Directors (the
"Committee"), which is composed of two non-employee directors.
Following review and approval by the Committee, all issues
pertaining to officer compensation are submitted to the full
Board for approval.  The primary objectives of the Company's
compensation program are to enable the Company to attract,
motivate and retain outstanding individuals and align their
success with that of the Company's stockholders through the
creation of stockholder value and achievement of strategic
corporate objectives.

          The level of compensation paid to an officer is
determined on the basis of the individual's overall
experience, responsibility, performance and compensation level
in his or her prior position (for newly hired officers), the
individual's overall performance and compensation level at the
Company during the prior year (for current employees), the
compensation levels of similarly situated individuals in the
pharmaceutical and biotechnology industries (including, but
not limited to, the biotechnology companies included in the
Dow Jones Medical and Biotechnology Index) and other labor
markets in which the Company competes for employees, the
performance of the Company's Common Stock during the prior
fiscal year and such other factors as may be appropriately
considered by the Board of Directors, by the Committee and by
management in making its initial proposals to the Committee.
For 1995, the performance of the Company's Common Stock had a
negative impact on the determination of compensation levels.
In light of the Company's cash position and as part of its
1994 restructuring, the Company instituted a salary freeze on
all employees from November of 1994 until January of 1996.




     

                             -15-



          Mr. Castello's compensation for 1995 was determined
after considering the general factors described above and the
terms of his existing employment contract.  In 1992, the
Committee approved, and recommended that the Board approve,
the terms of Mr. Castello's employment contract, as more fully
described under "Employment Contracts and Termination of
Employment and Change-in-Control Arrangements," because it
felt that the terms thereof were necessary in order to attract
a candidate of Mr. Castello's experience and reputation in the
pharmaceutical industry, which in turn was deemed necessary in
order to enable the Company to advance toward its long-range
goal of becoming a pharmaceutical company with commercially
viable products.

          The principal methods for long-term incentive
compensation are the Company's 1981 Stock Option Plan (the
"Option Plan") and Restricted Stock Plan (the "Restricted
Plan"), and compensation thereunder principally takes the form
of incentive and non-qualified stock option grants.  These
grants are designed to promote the convergence of long-term
interests between the Company's key employees and its
stockholders; specifically, the value of options granted will
increase or decrease with the value of the Company's Common
Stock.  In this manner, key individuals are rewarded
commensurately with increases in stockholder value.  These
grants also typically include a 5-year vesting period to
encourage continued employment.  The size of a particular
option grant is determined based on the individual's position
with and contribution to the Company.  For grants during the
past fiscal year, the number of options granted were
determined based on the numbers of options granted to such
individuals in the previous fiscal year, the aggregate number
of options held by each such individual, the number of options
granted to similarly situated individuals in the
pharmaceutical and biotechnology industries, the price of the
Company's common stock relative to other companies in such
industries and the resulting relative value of such options;
no specific measures of corporate performance were considered.
See "Proposal 2 - Addition of Shares to Employee Stock Option
Plans" for a further description of these two plans.

          Pursuant to the Option Plan and the Restricted Plan,
on January 11, 1995, the Company offered to exchange the
outstanding options of all employees, including the named
executives, holding options under the Option Plan, the
Restricted Plan and the International Genetic Engineering,
Inc. 1985 Nonqualified Stock Option Plan for replacement
options with an 

     

                             -16-



exercise price of $2.5625.  Each replacement option was
immediately exercisable with respect to 40% of the
shares of Common Stock underlying the option being replaced
and, as to the remaining shares, becomes exercisable in 48
equal, monthly installments beginning on the date of exchange.
In authorizing such action, the Board of Directors determined,
based on a variety of factors, including market conditions and
Company performance, that the current outstanding options did
not provide a meaningful incentive to the the executive
officers because the exercise prices of such options were, on
the average, significantly above the market price of the
Company's Common Stock.  The Committee believes that the
exchange offer was justified based on market conditions and
the reliance by the Company on non-cash compensation of its
officers.

          Certain employees are also compensated through the
Management Incentive Compensation Plan established effective
July 1, 1993 (as amended, the "Incentive Plan"), in which
management employees (other than the Chief Executive Officer),
as well as certain additional discretionary participants
chosen by the Chief Executive Officer, are eligible to
participate.  Under the Incentive Plan, at the beginning of
each fiscal year, the Board of Directors (with advice from the
Compensation Committee) establishes a target incentive
compensation pool, which is then adjusted at year-end to
reflect the Company's performance in achieving its corporate
objectives.

          After each fiscal year, the Board of Directors and
the Compensation Committee make a determination as to the
performance of the Company and Incentive Plan participants in
meeting corporate objectives and individual objectives, which
are determined from time to time by the Board of Directors in
its sole discretion and which included for 1995: a target
level of cash at year end; improvement in operating cash flow;
generation of current income; progress toward strategic
alliances, potential partnerships or financing arrangements;
and various objectives tied to development of the Company's
product lines.  Awards to Incentive Plan participants vary
depending upon the level of achievement of corporate
objectives, the size of the incentive compensation pool and
the Incentive Plan participants' base salaries and performance
during the fiscal year as well as their expected ongoing
contribution to the Company.  The Company must meet a minimum
percentage of its corporate objectives (currently 70%) before
any awards are made under the Incentive Plan.


     

                             -17-



          Awards under the Incentive Plan vest over a
three-year period with 50% of each award payable on a date to
be determined, expected to be in February or March of the
following fiscal year, and 25% payable on each of the next two
annual distribution dates, so long as the Incentive Plan
participant continues to participate in the Incentive Plan.
The portion payable on the first distribution date is payable
50% in cash and 50% in Common Stock (based on a 10-day average
market price).  Incentive Plan participants must choose prior
to the end of the first year of the three-year period whether
the balance is to be paid in cash or Common Stock.  All stock
issuances under the Incentive Plan are made pursuant to the
Company's Restricted Stock Plan.

          In 1994, the Committee determined that management
had not met the required corporate objectives and,
accordingly, no bonuses were awarded.  For 1995, the Committee
and the Board of Directors determined that management had met
a percentage of the corporate objectives summarized above in
excess of the 70% minimum required by the Plan in order to
make awards thereunder.  In 1995, 25 individuals were eligible
to participate in the Incentive Plan, including all of the
executive officers named in the "Summary Compensation Table"
above other than Mr. Castello.

Directors or its committees.




     

                             -23-



          In recognition of the important and unique services
provided by Mr. Van Ness to the Company's Board of Directors in
addition to his other business interests and responsibilities,
the Company issued 20,000 shares of its Common Stock to The Van
Ness 1983 Revocable Trust (the "Trust") in 1995 and has agreed,
following Mr. Van Ness' nomination to stand for re-election to
the Board of Directors at the Company's 1996 annual meeting of
stockholders, to issue an additional 5,000 shares of Common
Stock to the Trust.  The Company has registered the shares so
issued to the Trust with the Securities and Exchange
Commission.  

    PROPOSAL 2 - ADDITION OF SHARES TO EMPLOYEE STOCK PLANS

Background

          The Option Plan and the Restricted Plan (together the
"Stock Plans") are designed to encourage equity ownership of
the Company by the employees who are primarily responsible for
its management, growth and financial success and significant
independent consultants, and to assist the Company in
attracting and retaining the services of such employees and
consultants (see "Compensation Committee Report on Executive
Compensation" above). All employees are eligible to participate
in the Stock Plans (each, a "Participant").  Directors who are
not employees of the Company are not eligible to participate in
either plan.

          The Board of Directors has adopted, subject to
stockholder approval, amendments to these plans to increase the
aggregate number of shares of Common Stock issuable under the
two plans by 1,000,000 shares to 5,150,000 shares, and an
amendment to the Restricted Plan to increase the number of
shares of Common Stock issuable under that plan by 250,000
shares to 1,250,000 shares.  

          The essential features of the Option Plan and the
Restricted Plan, as amended, are summarized below.  These
summaries do not purport to be complete descriptions of these
plans.  Copies of actual plan documents may be obtained by
contacting the Secretary of the Company.

Description of Option Plan 

          As of April 24, 1996, the Company had authorized an
aggregate of 4,150,000 shares of Common Stock for issuance
under the Option Plan and the Restricted Plan, of which


     

                             -24-



approximately 575,519 shares of Common Stock had been issued
upon the exercise of options granted under the Option Plan and
2,694,476 shares of Common Stock were subject to outstanding
options under the Option Plan.  The expiration dates for all
such outstanding options range from September 21, 1996 (at the
earliest) to February 28, 2006 (at the latest).  If this
proposal is approved by the stockholders, 1,311,885 shares of
Common Stock will be available for issuance under future option
grants.

          The shares of Common Stock issuable over the term of
the Option Plan may be made available from either authorized
but unissued Common Stock or treasury shares.  Each option will
have an exercise price per share of not less than 100% of the
fair market value per share of Common Stock on the date of
grant.  The Option Plan's term expires on November 15, 2001.  

Description of Restricted Plan

          As of April 24, 1996, the Company had authorized
1,000,000 shares of Common Stock for issuance under the
Restricted Plan, subject to the limitation that not more than
4,150,000 shares may be issued in the aggregate under the
Restricted Plan and the Option Plan.  Approximately 140,400
shares of Common Stock had been issued either upon the exercise
of granted options or the direct issuance of shares under the
Restricted Plan and 427,720 shares of Common Stock were subject
to outstanding options under the Restricted Plan.  The
expiration dates for all such outstanding options range from
December 17, 1997 (at the earliest) to February 15, 2006 (at
the latest).  If this proposal is approved by the stockholders,
681,880 shares of Common Stock will be available for issuance
under future option grants or direct issuances.  
          
          The Restricted Plan authorizes the grant of options
to purchase shares of Common Stock (the "Option Grant Program")
as well as direct Common Stock issuances (the "Stock Issuance
Program").  The eligible individuals under the Restricted Plan
are employees (including officers and directors) and
consultants (other than non-employee directors) who provide
valuable services to the Company.  Such shares will be made
available from either authorized but unissued Common Stock or
treasury shares.

          Each option granted under the Option Grant Program
will have an exercise price of not less than 85% of fair market
value per share of Common Stock on the date of grant.  The


     

                             -25-



purchase price for shares issued under the Stock Issuance
Program may not be less than 85% of fair market value of the
Common Stock on the issuance date, which value will be
discounted if such shares are subject to the Company's right of
first refusal described below.  The Restricted Plan's term
expires on December 15, 2003.  

Provisions Common to Both Plans

          On December 3, 1991, the Board appointed its
Compensation Committee to administer the Stock Plans as each
relates to individuals other than directors, officers or
ten-percent stockholders of the Company for so long as the
members of the Compensation Committee are "disinterested
persons" within the meaning of Rule 16b-3 of the Securities
Exchange Act of 1934, as such term is interpreted from time to
time ("Rule 16b-3").  The Compensation Committee's authority to
grant options under the Stock Plans and to issue stock under
the Restricted Plan is limited to 15,000 shares per individual.
In all other respects, the Stock Plans are administered by the
Board.

          The Board and, with respect to individuals who are
not directors, officers or ten-percent stockholders of the
Company, the Compensation Committee (the "Plan Administrators")
are authorized (subject to the provisions of the Stock Plans)
to establish such rules and regulations as they may deem
appropriate for the proper administration of the Stock Plans.
Each option, whether granted under the Option Plan or the
Option Grant Program of the Restricted Plan, will be
exercisable at such times, during such period or periods, and
for such number of shares as the relevant Plan Administrator
determines.  No such granted option may have a term in excess
of ten years from the grant date.

          Exercise of Options.  The exercise price of options
granted under either plan will be immediately due upon exercise
of the option and may be paid (i) in cash; (ii) in shares of
Common Stock having a fair market value on the date the option
is exercised equal to the option price; (iii) in a combination
of cash and shares of Common Stock valued at fair market value
on the day the option is exercised; or (iv) through a
broker-dealer sale and remittance procedure pursuant to which
shares acquired under the option are sold immediately and there
is paid to the Company, out of the sale proceeds, an amount
equal to the option price for the acquired shares plus all
applicable withholding taxes.  For all purposes of valuation
under either of the Stock Plans, the fair market value of the


     

                             -26-



Common Stock on any relevant date will be the closing sale
price per share of Common Stock, as reported for such date
through the Nasdaq National Market.  

          The relevant Plan Administrator may also assist any
optionee in the exercise of an option by authorizing a loan
from the Company, by permitting the optionee to pay the option
price in installments over a period of years or by authorizing
a guarantee by the Company of a third party loan to the
optionee, the terms and conditions of which will be established
by the relevant Plan Administrator in its sole discretion.
However, the maximum credit available to the optionee may not
exceed the option price payable for the purchased shares, plus
any tax liability.

          The Stock Plans have been amended to eliminate the
provisions giving the relevant Plan Administrator specific
authority to cancel options with the consent of the affected
optionees and to grant in substitution therefor new options
covering the same or different numbers of shares of Common
Stock, but having an option price per share not less than 100%
(in the case of the Option Plan) or 85% (in the case of the
Option Grant Program) of the fair market value on a new grant
date.  Such amendments do not, however, affect the Company's
ability to cancel options with the consent of the optionee at
any time and simultaneously or subsequently to grant options to
the same or different optionees at exercise prices otherwise
permissible under the Stock Plans.

          Termination of Employment.  Should an optionee under
either plan cease to be an employee or consultant of the
Company for any reason (including death or permanent
disability), such optionee will not have more than a twelve
(12) month period following the date of such cessation of
status in which to exercise any outstanding options, but under
no circumstances may any such options be exercised after the
specified expiration date of the option term.  

          Stock Appreciation and Repurchase Rights.  The Option
Plan and the Option Grant Program each include a stock
appreciation right feature whereby the relevant Plan
Administrator has the authority to grant one or more optionees
the right, exercisable upon such terms and conditions as such
Plan Administrator deems appropriate, to surrender all or part
of an unexercised option and to receive in exchange therefor an
amount equal to the excess of (i) the fair market value (on the
date of surrender) of the number of vested shares for which the


     

                             -27-



surrendered option is at the time exercisable over (ii) the
aggregate option price payable for such vested shares, payable
in shares of Common Stock valued at fair market value on the
date of surrender, in cash, or partly in shares and partly in
cash.

          Acceleration of Options.  Pursuant to certain
corporate transactions, including: a merger or acquisition in
which the Company is not the surviving entity; the sale,
transfer or other disposition of all or substantially all of
the assets of the Company; or any other business combination in
which 50% or more of the Company's outstanding voting stock is
transferred to different holders in a single transaction or a
series of related transactions, all options at the time
outstanding and not then otherwise fully exercisable will
immediately, prior to the specified effective date of such
corporate transaction, become fully exercisable for up to the
total number of shares of Common Stock purchasable thereunder.  

          Amendment.  The Stock Plans permit the grant of
options to purchase shares of Common Stock in excess of the
number of shares then available for issuance.  Any option so
granted cannot be exercised prior to stockholder approval of an
amendment increasing the number of shares available for
issuance under the Option Plan or the Restricted Plan, as the
case may be.

          The Board has full power and authority to amend or
modify the Stock Plans in any or all respects, except that no
such amendment or modification may, without the consent of the
option holders, adversely affect rights and obligations with
respect to options at the time outstanding under either of the
Stock Plans, nor adversely affect the rights of any individual
with respect to the Common Stock issued pursuant to the
Restricted Plan prior to such action, and the Board may not,
without the approval of the Company's stockholders, (i)
increase the maximum number of shares issuable under the Option
Plan or the Restricted Plan, except for permissible adjustments
in the event of certain changes in the Company's
capitalization, (ii) materially increase the benefits accruing
to participants in the Stock Plans or (iii) materially modify
the eligibility requirements for participation therein.

          Although the Stock Plans have not yet been amended to
comply with the most recent amendments to Rule 16b-3 under the
Securities Exchange Act of 1934, as amended (the phase-in
period for compliance with such amendments having been extended


     

                             -28-



until September 1, 1996), the Company intends to do so and does
not anticipate that any stockholder action will be required in
connection therewith.

Description of Stock Issuance Program

          Common Stock will be issued to eligible individuals
under the Stock Issuance Program upon such terms and conditions
and for such numbers of shares as is determined by the relevant
Plan Administrator and may be fully vested upon issuance or may
vest over such period of time as such Plan Administrator deems
appropriate.  Shares may be issued under the Stock Issuance
Program for such consideration as the relevant Plan
Administrator may from time to time determine, provided that in
no event may shares be issued for consideration other than (i)
cash or cash equivalents; (ii) shares of Common Stock valued at
fair market value; (iii) the promissory note of the purchaser
payable to the Company's order, which may be subject to
cancellation by the Company in whole or in part upon such terms
or conditions as the Plan Administrator may determine; or (iv)
payment effected through a broker-dealer sale and remittance
procedure.

          If a participant is issued shares under the Stock
Issuance Program which are not fully vested at the time of
issuance, then such shares will be subject to certain
repurchase rights of the Company, exercisable in the event the
individual ceases to retain his/her employee or service status
for any reason, and will allow the Company to repurchase the
participant's unvested shares at the lesser of (i) the original
purchase price paid by such individual or (ii) if such shares
are subject to the Company's first refusal rights, the fair
market value of such shares appropriately discounted for the
Company's first refusal rights.  The vesting schedule
applicable to each issuance will be determined by the relevant
Plan Administrator at the time of issuance.  The relevant Plan
Administrator may accelerate the vesting of the issued shares,
in whole or in part, at the time of the participant's
termination.

          The issued shares may, in the discretion of the
relevant Plan Administrator, be subject to a permanent right of
first refusal.  Prior to any sale or other disposition of the
shares subject to such right, the participant must first offer
to sell the shares to the Company (or its assigns) at a price
equal to the difference between the fair market value of the
shares on the date of repurchase (determined in accordance with


     

                             -29-



the normal valuation provisions of the Restricted Plan, without
regard to the Company's permanent right of first refusal) and
the price differential determined by the relevant Plan
Administrator at the time of issuance.

Federal Income Tax Consequences

          The following discussion summarizes the principal
federal income tax consequences of the Stock Plans.  This
discussion is based on current provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), the Treasury
regulations promulgated thereunder, and administrative and
judicial interpretations thereof as in effect on the date
hereof.  The summary does not address any foreign, state or
local tax consequences of participation in the Stock Plans.

          1.   Stock Options.  In general, the grant of an
option will not be a taxable event to the recipient and it will
not result in a deduction to the Company.  The tax consequences
associated with the exercise of an option and the subsequent
disposition of shares of Common Stock acquired on the exercise
of such option depend on whether the option is an incentive
stock option or a non-qualified stock option.

          Upon the exercise of a non-qualified stock option,
the Participant will recognize ordinary taxable income equal to
the excess of the fair market value of the shares of Common
Stock received upon exercise over the exercise price.  The
Company will generally be able to claim a deduction in an
equivalent amount.  Any gain or loss upon a subsequent sale or
exchange of the shares of Common Stock will be capital gain or
loss, long-term or short-term, depending on the holding period
for the shares of Common Stock.

          Generally, a Participant will not recognize ordinary
taxable income at the time of exercise of an incentive stock
option and no deduction will be available to the Company,
provided the option is exercised while the Participant is an
employee or within three months following termination of
employment (longer, in the case of termination of employment by
reason of disability or death).  If an incentive stock option
granted under the Option Plan is exercised after these periods,
the exercise will be treated for U.S. federal income tax
purposes as the exercise of a non-qualified stock option.
Also, an incentive stock option granted under the Option Plan
will be treated as a non-qualified stock option to the extent
it (together with any other incentive stock options granted after

     

                             -30-



1986 under other plans of the Company and its subsidiaries)
first becomes exercisable in any calendar year for shares
of Common Stock having a fair market value, determined as
of the date of grant, in excess of $100,000.

          If shares of Common Stock acquired upon exercise of
an incentive stock option are sold or exchanged more than one
year after the date of exercise and more than two years from
the date of grant of the option, any gain or loss will be long-
term capital gain or loss.  If shares of Common Stock acquired
upon exercise of an incentive stock option are disposed of
prior to the expiration of these one-year or two-year holding
periods (a "Disqualifying Disposition"), the Participant will
recognize ordinary income at the time of disposition, and the
Company will generally be able to claim a deduction, in an
amount equal to the excess of the fair market value of the
shares of Common Stock at the date of exercise over the
exercise price.  Any additional gain will be treated as capital
gain, long-term or short-term, depending on how long the shares
of Common Stock have been held.  Where shares of Common Stock
are sold or exchanged in a Disqualifying Disposition (other
than certain related party transactions) for an amount less
than their fair market value at the date of exercise, any
ordinary income recognized in connection with the Disqualifying
Disposition will be limited to the amount of gain, if any,
recognized in the sale or exchange, and any loss will be a
long-term or short-term capital loss, depending on how long the
shares of Common Stock have been held.

          Although the exercise of an incentive stock option as
described above would not produce ordinary taxable income to
the Participant, it would result in an increase in the
Participant's alternative minimum taxable income and may result
in an alternative minimum tax liability.

          2.   Stock Awards.  A Participant who receives a
share award will generally recognize ordinary income at the
time the restrictions on transferability lapse, and if there
are no restrictions on transferability, at the time of the
award.  The amount of ordinary income so recognized will be the
fair market value of the Common Stock at the time the income is
recognized, determined without regard to any restrictions other
than restrictions which by their terms will never lapse, over
the amount, if any, paid for the stock.  This amount is
generally deductible for federal income tax purposes by the
Company.  Dividends paid with respect to Common Stock that is


     

                             -31-



nontransferable will be ordinary compensation income to the
Participant (and generally deductible by the Company).

          In lieu of the treatment described above, a
Participant may elect immediate recognition of income under
Section 83(b) of the Code.  In such event, the Participant will
recognize as income the fair market value of the restricted
stock at the time of grant (determined without regard to any
restrictions other than restrictions which by their terms will
never lapse), and the Company will generally be entitled to a
corresponding deduction.  Dividends paid with respect to shares
as to which a proper Section 83(b) election has been made will
not be deductible to the Company.  If a Section 83(b) election
is made and the stock is subsequently forfeited, the
Participant will generally be entitled to an offsetting tax
deduction only to the extent of the amount paid, if any, for
the stock.

          3.   Stock Appreciation Rights.  With respect to
stock appreciation rights under the Stock Plans, generally,
when a Participant receives payment with respect to a stock
appreciation right granted to him or her under the Stock Plans,
the amount of cash and the fair market value of any other
property received will be ordinary income to such Participant
and will be allowed as a deduction for federal income tax
purposes to the Company.

          4.   Special Rules.  Special rules may apply to a
Participant who is subject to Section 16(b) of the Securities
Exchange Act of 1934 as in effect from time to time (generally
directors, officers and 10% stockholders).  Certain additional
special rules apply if the exercise price for an option is paid
in shares previously owned by the optionee rather than in cash.

          5.   Limitation on Deductibility.  Section 162(m) of
the Code, effective for tax years beginning after 1993,
generally limits the deductible amount of annual compensation
paid (including, unless an exception applies, compensation
otherwise deductible in connection with awards granted under
the Stock Plans) by a public company to a "covered employee"
(the chief executive officer and four other most highly
compensated executive officers of the Company) to no more than
$1 million.  It is possible that certain amounts otherwise
deductible in connection with the Stock Plans may be subject to
this deduction limit.




     

                             -32-



Recommendation

          At the annual meeting, the Company's stockholders
will be asked to approve the proposal to amend the Stock Plans
to increase the total number of shares authorized under both
plans by 1,000,000 shares to 5,150,000 shares and to amend the
Restricted Plan to increase the number of shares issuable over
the term of such plan by 250,000 shares to 1,250,000 shares
(subject to the limitation that not more than 5,150,00 shares
may be issued in the aggregate under the Restricted Plan and
the Option Plan).  The Board of Directors believes that
approval of the proposed amendments is in the best interests of
the Company, its stockholders and its employees and unanimously
recommends a vote "FOR" approval.  Approval of the amendments
requires the affirmative vote of the holders of a majority of
the shares of Common Stock of the Company represented in person
or by proxy at the annual meeting and entitled to vote.

          PROPOSAL 3 - APPROVAL OF AMENDMENTS TO THE RESTATED
CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF
AUTHORIZED SHARES

Background

          Pursuant to Article IV of the Company's Restated
Certificate of Incorporation, the Company is authorized to
issue 40,000,000 shares of Common Stock, par value $.0005 per
share, and 1,000,000 shares of preferred stock, par value $.05
per share ("Preferred Stock").  On April 24, 1996, the Company
had issued and outstanding 31,581,420 shares of Common Stock.
In addition, 650,000  shares of Preferred Stock have been
designated Series A Cumulative Preferred Stock (the "Series A
Preferred Stock"), of which none were outstanding on April 24,
1996, 30,000 shares of Preferred Stock have been designated
Senior Convertible Preferred Stock, Series B (the "Series B
Preferred Stock"), of which 7,807 shares were outstanding on
such date, 5,000 shares of Preferred Stock have been designated
Non-Voting Cumulative Convertible Preferred Stock, Series D,
all of which were outstanding on such date, and 7,500 shares of
Preferred Stock have been designated Convertible Preferred
Stock, Series E (the "Series E Preferred Stock"), of which none
were outstanding on such date.

          On February 28, 1996, the Board of Directors
unanimously approved amendments to Article IV of the Restated
Certificate of Incorporation of the Company which would
increase the number of authorized shares of Common Stock by
30,000,000 

     

                             -33-



shares to 70,000,000 shares and increase the number
of authorized shares of Preferred Stock by 500,000 to
1,500,000.  

Description of the Proposed Amendment to Increase the Number of
Authorized Shares of Common Stock

          The Board of Directors of the Company considers it
prudent and in the best interests of the Company and its
stockholders to have a substantial number of shares of Common
Stock authorized by the Restated Certificate of Incorporation
which are available for issuance, in order to provide the
Company with financing and business flexibility.  Common Stock
may be issued by the Company in connection with future
acquisitions or equity financings, upon conversion or exchange
of outstanding securities, in connection with the Stock Plans,
the Incentive Plan, the Directors Plan or other employee
benefit plans or under other circumstances.  There are
currently no agreements or understandings regarding the
issuance of any of the additional shares of Common Stock that
would become available if the Company's Restated Certificate of
Incorporation is amended.

          The additional shares of Common Stock for which
authorization is sought would be part of the existing class of
Common Stock, and, to the extent issued, would have the same
rights and privileges as the shares of Common Stock currently
outstanding.  No holder of the Common Stock is entitled to any
preemptive right to subscribe for or purchase any stock or
other securities of the Company.  The issuance of a substantial
amount of Common Stock or the granting of an option to purchase
a substantial amount of Common Stock could have a potential
anti-takeover effect with respect to the Company which may make
it more difficult to effect a change in control of the Company
(for example, by decreasing the percentage of share ownership
of those persons seeking to obtain control), although the Board
of Directors is not presenting the proposal for that reason and
does not presently anticipate using the increased authorized
shares for such a purpose.  Under applicable law, the Board of
Directors is required to make any determination to issue such
stock based on its judgment as to the best interest of the
Company and its stockholders at the time of such issuance. 

          If such proposal is not adopted, approximately
8,418,580 of the currently authorized 40,000,000 shares of
Common Stock will be available for future issuances (including
upon exercise of outstanding stock options) and approximately
1,428,885 shares will be reserved for issuance in connection
with options or shares to be granted under existing director


     

                             -34-



and employee stock-based plans (assuming Proposal 2 herein is
approved at the annual meeting).  

Description of the Proposed Amendment to Increase the Number of
Authorized Shares of Preferred Stock

          The Board of Directors of the Company considers it
prudent and in the best interests of the Company and its
stockholders to have a substantial number of shares of
Preferred Stock authorized by the Restated Certificate of
Incorporation which are available for issuance, in order to
provide the Company with financing and business flexibility.
Preferred Stock may be issued by the Company in connection with
future acquisitions or equity financings or under other
circumstances.  There are currently no agreements or
understandings regarding the issuance of any of the additional
shares of Preferred Stock that would become available if the
Company's Restated Certificate of Incorporation is amended.

          Under the Restated Certificate of Incorporation, the
Board of Directors has the authority by resolution, without any
action of the stockholders, to issue from time to time up to
the aggregate number of authorized shares of Preferred Stock.
Such resolutions may authorize issuance in one or more series
and may fix and determine dividend and liquidation preferences,
voting rights, conversion privileges, redemption terms and
other privileges and rights of stockholders of each series so
authorized.  Consequently, the additional shares of Preferred
Stock for which authorization is sought, to the extent issued,
may or may not have the same rights and privileges as the
shares of Preferred Stock currently outstanding.  No holder of
the Preferred Stock currently outstanding is entitled to any
preemptive right to subscribe for or purchase any stock or
other securities of the Company, but any future series of
Preferred Stock may or may not include such rights.  The
issuance of shares of Preferred Stock or the granting of an
option to purchase Preferred Stock could have a potential
anti-takeover effect with respect to the Company which may make
it more difficult to effect a change in control of the Company,
depending on the preferences, rights, privileges or other terms
fixed by the Board of Directors with respect to such series,
although the Board of Directors is not presenting the proposal
for that reason and does not presently anticipate using the
increased authorized shares for such a purpose.  Under
applicable law, the Board of Directors is required to make any
determination to issue such stock based on its judgment as to
the best interest of the Company and its stockholders at the
time of such 

     

                             -35-



issuance.  The Board of Directors does not currently intend
to seek authorization by its security holders prior to
any future issuance of Preferred Stock, unless such
action is required by applicable law or the rules of any stock
market on which the Company's securities may be traded.

          If such proposal is not adopted, approximately
987,193 of the currently authorized 1,000,000 shares of
Preferred Stock will be available for future issuances, 679,693
of which have been previously designated as either Series A
Preferred Stock, Series B Preferred Stock or Series E Preferred
Stock.

Recommendation

          At the annual meeting, the Company's stockholders
will be asked to:

          (a)  approve the proposal to amend the Restated
               Certificate of Incorporation to increase the
               number of authorized shares of Common Stock by
               30,000,000 to 70,000,000 shares and

          (b)  approve the proposal to amend the Restated
               Certificate of Incorporation to increase the
               number of authorized shares of Preferred Stock
               by 500,000 to 1,500,000.  

          Each such proposal will be considered and voted upon
separately, and neither proposal is conditioned upon approval
of the other.

          The Board of Directors believes that the approval of
such amendments is in the best interests of the Company and its
stockholders and unanimously recommends a vote "FOR" approval.
Approval of each amendment requires the affirmative vote of the
holders of a majority of the shares of Common Stock of the
Company entitled to vote.

     PROPOSAL 4 - RATIFICATION OF INDEPENDENT ACCOUNTANTS

          The Board of Directors, on the recommendation of its
audit committee, has selected Arthur Andersen LLP to serve as
the Company's independent accountants for 1996.  Arthur
Andersen LLP has been acting as the Company's independent
accountants since fiscal year 1983.


     

                             -36-



          The ratification of the appointment of Arthur
Andersen LLP is being submitted to the stockholders at the
annual meeting.  If such appointment is not ratified, the Board
of Directors will consider the appointment of other auditors.
The Board of Directors recommends a vote "FOR" the ratification
of the appointment of Arthur Andersen LLP as the Company's
independent accountants for the 1996 fiscal year.

          A representative of Arthur Andersen LLP is expected
to be present at the meeting with an opportunity, if desired,
to make a statement and to respond to your questions. 

                     CERTAIN TRANSACTIONS

          Pursuant to his employment agreement, the Company
paid Mr. Mendell $125,000 in 1995.  See "Employment Contracts
and Termination of Employment and Change-in-Control
Arrangements."

          Pursuant to his employment agreement, in 1993 the
Company made a loan to Dr. Scannon, its Chief Scientific and
Medical Officer and a Director, in the amount of $290,000.  See
"Employment Contracts and Termination of Employment and Change-
in-Control Arrangements."  As of April 30, 1996, $293,000 of
principal and interest on the loan remained outstanding and
$50,000 in principal and interest payments have been received
by the Company.

          Pursuant to his employment agreement dated July 14,
1992, the Company made a loan to Dr. Nadav Friedmann, its
former Vice President, Clinical Research, in the amount of
$100,000.  Dr. Friedmann resigned and such employment agreement
was terminated effective January 31, 1995.  Approximately
one-third of the loan has been repaid and the balance was
forgiven pursuant to the terms of such employment agreement.

Compliance with Section 16(a) of the Securities Exchange Act of
1934

          Section 16(a) of the Securities Exchange Act of 1934

on a timely basis.
