July 19, 1995


TO OUR SHAREHOLDERS:

The mission of OXIS International, Inc., (OXIS) is to become a world leader in
the development of technologies and products to treat and prevent diseases
associated with damage from oxygen derived free radicals (diseases of oxidative
stress). During the last year, we made major progress toward accomplishing our
mission. OXIS advanced its research and development programs, received
regulatory approvals for potential products, raised needed capital and made
another key acquisition.

We added complementary technologies through the acquisition of an additional
company, Therox Pharmaceuticals, Inc., which was founded and financed by S.R.
One, Limited (venture investment arm of SmithKline Beecham) and Brantley Venture
Partners II, L.P. Therox, originally founded to pursue the development of novel
antioxidant therapeutics, complements and extends the OXIS technology portfolio
through the addition of patents and corporate and university partnerships. The
Therox technology portfolio expands our opportunity to develop novel high-value
therapeutics to treat free radical associated diseases and balances the OXIS
pipeline though the addition of mid-term product opportunities. Therox has
focused its efforts on the discovery and development of new molecules that
combine antioxidant activity with other key therapeutic effects. We anticipate
the expanded OXIS portfolio will represent a significant source of new drug
candidates for the pharmaceutical industry. This transaction also brought $1.5
million in cash to the Company in exchange for OXIS Series B Preferred Stock.

Fund Raising
- ------------

Following the September 7, 1994, merger of DDI Pharmaceuticals, Inc. with
International BioClinical, Inc., and acquisition of Bioxytech, S.A. to form OXIS
International, Inc., raising the initial funds required to achieve our mission
became our major focus, as detailed in our letter to you in April. We are
pleased to report to you that despite a nearly catastrophic downturn in the
biotechnology capital markets, we have successfully raised significant capital
and are in the process of working towards the private placement of additioanal
securities.

Prior to completing the Therox acquisition, we successfully raised $2.1 million
in capital through a Canadian-based investment banking firm, Bailey & Company,
and secured two major loans to the Company. The first of these loans was granted
to OXIS in February 1995, when certain former shareholders of Bioxytech advanced
the Company $766,000 under promissory notes payable in 1996. An additional loan
of $600,000 was granted to OXIS by our major customer, Sanofi Winthrop, which we
plan to repay in the next few months. In total, we have raised over $4.9 million
since our fundraising efforts began in October of 1994.

Although raising these funds represented a consuming effort for the Company's
senior management, we would not have been successful in this difficult market
without a strong technology portfolio and effective strategy for product
development. To ensure that we capitalize on our current momentum, we are
proceeding rapidly to raise additional funds to accelerate the development of
our key therapeutics technologies. Therefore, OXIS is pursuing raising up to an
additional five million dollars if available on attractive terms. Although we
remain optimistic about our ability to attract investments, there are no
assurances that the additional funds will be secured.

                                       1

Operations
- ----------

We are also pleased to report that in addition to our success in fund raising,
the Company also made remarkable progress in other areas during this period.
OXIS has reported on several key technical advances, increased its distribution
capabilities, increased sales of selected products and made significant progress
in increasing cost-effectiveness and efficiency through our integration efforts.
Specifically, since September 7, 1994, OXIS has achieved several key technical,
business development and operational milestones, including:

  .       The Company has entered into discussions with Sanofi Winthrop with
     respect to license and supply agreements for OXIS' orgotein (bovine
     superoxide dismutase or bSOD), and to explore a potential license agreement
     for its polyethylene glycol (PEG)-coupled recombinant human SOD. These
     discussions anticipate the completion and analysis of Sanofi's current
     Phase III trial which employs a PEG-coupled form of OXIS' bSOD for
     treatment of head trauma.

  .       The U.S. Food and Drug Administration ("FDA") awarded Orphan Drug
     designation for the Company's bSOD for the treatment of familial
     amyotrophic lateral sclerosis ("FALS"). This designation may accelerate the
     drug registration process and could provide market exclusivity following
     approval. The Company recently held discussions with the FDA regarding the
     requirements for an Investigational New Drug Application ("IND") for this
     drug.

  .       The Company's orgotein for veterinary applications, Palosein, received
     registration approval for sale in Canada. The drug is used primarily to
     treat chronic and acute inflammatory conditions in dogs and horses. Sales
     of this drug, reintroduced to the market in 1993, increased to $190,000 in
     the first quarter of 1995, from $71,000 in the first quarter of 1994.

  .       OXIS received approval from the FDA for its 510(k) application to
     market its new product, Beta Lactamase Rapid Enzyme Detection Discs. This
     product detects an enzyme called beta lactamase that is produced by certain
     antibiotic-resistant bacteria. The Company is currently in discussions with
     a potential major alliance partner to commercialize this assay and
     subsequent assays for antibiotic-resistance screening.

  .       We have achieved significant progress in the development of our
     selenium-based molecules that act as mimics of the enzyme, glutathione
     peroxidase. An international development plan is underway for the
     preclinical development of these low molecular weight antioxidants, with
     studies planned to begin at Emory University before the end of 1995. Our
     goal is to file an IND on this drug for the treatment of restenosis
     following angioplasty in 1996. This is an aggressive schedule, but barring
     any unanticipated problems, we should achieve this key milestone in the
     coming year.

  .       The Company has acquired additional key distributors for its research
     assays to monitor markers of oxidative stress. The Company currently
     markets six assays to measure markers of oxidative stress to the research
     market. These additional distributors will allow the Company to increase
     sales of these innovative assays.

                                       2
<PAGE>
 
  .        Finally, integration of the programs, sites and personnel required to
     achieve improved operating efficiency and optimize the Company's research
     and development capabilities is progressing. Several functions, including
     payroll, accounting, purchasing, and other administrative activities, have
     been combined for the U.S. operations. The Mountain View site will be
     closed October 31, 1995, and its functions will be relocated to other
     appropriate sites. Negotiations are ongoing to reduce costs of facilities
     and equipment in our French operations, and all activities at this site are
     being evaluated for their cost effectiveness. International project teams
     are being formed to pursue the Company's key projects, and all regulatory
     affairs and quality assurance functions for the Company are being
     centralized. Selective staff reductions have occurred and will continue to
     be considered to ensure optimal use of our research and development funds.
     Overall, integration activities have been difficult in the face of the need
     to raise additional capital, but considerable progress has been made to
     date, and this area will continue to be a major focus for senior
     management.


The past 11 months have been extremely challenging.  However, we have achieved a
significant level of success in our fund-raising efforts.  The acquisition of
Therox represents an opportunity to add complementary technologies, therapeutics
research and collaborations, and additional strength in pharmaceutical
development and synthetic chemistry to develop novel antioxidant technologies.
The coming months will continue to be challenging.  We will continue to focus on
the enhancement of our revenue base, the acquisition of capital and the
integration of our operations to ensure that our technology development programs
move forward in an optimal manner.

The Company is well-positioned to take advantage of what it views as a
developing market for new diagnostic tools and therapeutic products to treat and
prevent diseases associated with damage from uncontrolled oxygen free radicals
(diseases of oxidative stress).  The Company's current therapeutics portfolio
together with the complementary technologies associated with the Therox
acquisition positions OXIS to achieve its mission and partially support its
development activities through profits from its current products.

An overview of 1994 financial information on the Company can be found in the
enclosed 1994 Annual Report on Form 10-K.

We appreciate your continued support and assure you that we will do everything
possible to ensure the success of OXIS and increase shareholder value.

Sincerely,

Ray R. Rogers                 Anna D. Barker, Ph.D.

                                PROXY STATEMENT

                      FOR ANNUAL MEETING OF STOCKHOLDERS
                         TO BE HELD ON AUGUST 15, 1995

                                                                   July 19, 1995

To the Stockholders:

     This Proxy Statement is furnished to you in connection with the
solicitation by the Board of Directors of OXIS International, Inc., 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 Heathman Hotel, 1001 SW
Broadway, Portland, Oregon 97205, on Tuesday, August 15, 1995 at 2:00 p.m.
(local time) and at any subsequent time which may be necessary by the
adjournment thereof.

     If you were a holder of record of Common Stock of the Company (the "Common
Stock") at the close of business on July 10, 1995, you are entitled to vote at
the meeting and your presence is desired. However, to assure your representation
at the meeting, you are urged by the Board of Directors of the Company to sign
and return the enclosed Proxy as soon as possible. You can, of course, revoke
your Proxy at any time before it is voted if you so desire, either in person at
the meeting or by delivery of a duly executed written statement to that effect
to the Secretary of the Company.

     The Company is paying all costs of the solicitation of Proxies, including
the expenses of printing and mailing to its stockholders this Proxy Statement,
the accompanying Notice of Annual Meeting of Stockholders and form of Proxy,
letter to shareholders and the Annual Report on Form 10-K. The Company has
engaged D.F. King & Co. to assist the Company in the distribution and
solicitation of Proxies and has agreed to pay D.F. King & Co. a fee of $3,500
plus expenses for its services. The Company will also reimburse brokerage houses
and other custodians, nominees and fiduciaries for their expenses, in accordance
with the regulations of the Securities and Exchange Commission, in sending
Proxies and proxy materials to the beneficial owners of the Company's Common
Stock. Officers or employees of the Company may also solicit Proxies in person,
or by mail, telegram or telephone, but such persons will receive no compensation
for such work, other than their normal compensation as such officers or
employees.

     At the close of business on July 10, 1995, 10,683,687 shares of Common
Stock were outstanding and are entitled to vote at the Annual Meeting. Each
share of Common Stock

                                       5
<PAGE>
 
outstanding as of the July 10, 1995 record date is entitled to one vote. This
Proxy Statement and the enclosed Proxy are first being mailed to the
stockholders of the Company on or about July 19, 1995.


                           PROXIES AND VOTE REQUIRED

     The persons named in the accompanying form of Proxy intend to vote Proxies
FOR (i) the election of the nominees for director named herein except to the
extent that authority to vote for any such nominee is withheld, (ii) the
approval of the amendment to the 1994 Incentive Stock Plan to increase the
number of shares of Common Stock available for issuance thereunder by 800,000 to
an aggregate of 1,200,000 shares, except to the extent a Proxy indicates
otherwise. In the event that any nominee at the time of election shall be unable
or unwilling to serve or is otherwise unavailable for election (which
contingency is not now contemplated or foreseen), and in consequence another
individual shall be nominated, the persons named in the form of Proxy shall have
the discretion and authority to vote or to refrain from voting in accordance
with their judgment on such other nominations.

     The presence in person or by proxy of a majority of the shares of Common
Stock outstanding and entitled to vote at the meeting is required for a quorum.
If a quorum is present those nominees receiving a plurality of the votes cast
will be elected. Accordingly, shares not voted in the election of directors
(including shares covered by a proxy as to which authority is withheld to vote
for all nominees) and shares not voted for any particular nominee (including
shares covered by a Proxy as to which authority is withheld to vote for only one
or less than all of the identified nominees) will not prevent the election of
any of the nominees for director. Approval of the proposal to increase the
number of shares available for issuance under the 1994 Stock Incentive Plan
requires the affirmative vote of the majority of the shares of Common Stock
entitled to vote and present in person or represented by proxy, and abstentions
will be treated as votes against. For any other matter submitted to stockholders
at the meeting, if a quorum is present the affirmative vote of the majority of
the shares voted is required for approval. As a result, abstention votes have
the effect of a vote against such matters.

     "Broker Non-Votes" occur when a broker holding shares of stock in street
name withholds his vote on certain non-routine matters because the broker has
not received instructions from the beneficial owner of those shares of stock and
does not have discretionary authority to vote on such non-routine matters
without such instructions. Under the Rules of the New York Stock Exchange,
brokers holding shares of stock in street name must receive specific
instructions from the beneficial owners in order to have the authority to vote,
in person or by proxy, on certain "non-routine" matters as defined under those
Rules. When a beneficial owner does not give specific instructions to the
broker, the broker, as the holder of record, is entitled to vote only on
"routine" matters and must withhold its votes as to any non-routine matters.
Where a proxy solicitation includes a non-routine proposal and the broker does
not receive specific instructions from the beneficial owner, the resulting proxy
is considered a "limited proxy". Shares represented by limited proxies are
considered present for quorum purposes. However, shares represented by

                                       6
<PAGE>
 
limited proxies are not considered present for purposes of determining the total
number of shares with voting power present with regard to a non-routine
proposal. The resulting broker non-vote will not be counted for or against such
non-routine proposal.

     Proposal 2 (approval of the proposal to increase the number of shares
available for issuance under the Company's 1994 Stock Incentive Plan) is a "non-
routine" proposal. Shares represented by limited proxies are not considered
present for purposes of determining the total number of shares with voting power
present with regard to this proposal. Broker non-votes will not be counted for
or against this proposal. Proposal 1 (Election of Directors) is a "routine"
matter upon which brokers can cast votes with or without specific instructions
from the beneficial holders and are thus counted for purposes of determining
whether the Proposal has been approved.


                    PROPOSAL NO. 1 -- ELECTION OF DIRECTORS
                            (ITEM 1 ON PROXY CARD)

     The Board of Directors of the Company currently consists of eight
individuals, all of whom have been nominated for election at the meeting.
Directors are to be elected to hold office until the next Annual Meeting of
Stockholders or until their respective successors shall have been elected and
qualified. The names and ages of the eight nominees for director are set forth
below :

STOCK PURCHASE WARRANTS                                                         

     In prior years, the Company issued warrants to purchase shares of Common
Stock to certain officers and key employees (some of whom no longer hold any
position with the Company) and to former directors.

     Upon exercise of a warrant, the purchase price for the number of shares
being purchased is payable in cash. Warrants contain provisions for adjustments
in the event of stock splits, stock dividends, reorganizations and similar
events. Subject to satisfaction of certain conditions, the Company has agreed to
register, pursuant to the Securities Act of 1933, as amended (the "Securities
Act") the shares purchased upon exercise of the warrants.

     Warrants are taxed as stock options which do not meet the requirements of
the Internal Revenue Code of 1986 for incentive stock options. As a consequence,
warrants do not receive the favorable tax treatment accorded to incentive stock
options. Generally, upon exercise or transfer of a warrant, the holder of the
warrant realizes ordinary taxable income, and the Company realizes a tax
deduction, equal to the difference between the exercise price and the fair
market value of the shares at the time, without regard to legal restrictions on
transfer of the shares in the event the shares received are not registered
pursuant to the Securities Act.

All warrants issued to officers, directors and present key employees are
exercisable at $2.875 per are and expire through December 31, 1999.

At December 31, 1994, Dr. Mark G.P. Saifer held warrants to purchase 195,000
shares of the Company's Common Stock. The closing price of the Company's Common
Stock on December 30, 1994, was $1.75. Therefore, these warrants were not "In-
the-Money" at December 31, 1994.

STOCK OPTIONS

     In September 1994, the Company's shareholders approved the 1994 Stock
Incentive Plan under which 400,000 shares of the Company's Common Stock are
reserved for issuance. The plan permits granting stock options to acquire shares
of the Company's Common Stock, awarding stock bonuses of the Company's Common
Stock, and granting stock appreciation rights. As of December 31, 1994, the
Company had granted options to purchase 90,000 shares of the Company's Common
Stock under this plan. Options to purchase 15,000 shares of the Company's Common
Stock at an exercise price of $3.50 per share were granted to directors Barker,
Brown, Mayer, Sitaraman and Taussig. Options to purchase 15,000 shares of the
Company's Common Stock at an exercise price of $3.13 were granted to Dr.
Needham.

     In addition, options to purchase 214,700 shares of the Company's Common
Stock, exercisable at $3.55 per share, were granted in connection with the 1994
acquisitions of Bioxytech and IBC. Mr. Rogers and Dr. Barker each received
20,000 of such stock options.

PROPOSAL NO. 2 -- APPROVAL OF AMENDMENT TO 1994 STOCK INCENTIVE PLAN (ITEM 2 ON
                                  PROXY CARD)

     The Company's Board of Directors and stockholders have previously approved
the adoption of the Company's 1994 Stock Incentive Plan (the "Plan") and the
reservation of 400,000 shares of the Company's Common Stock for issuance
thereunder. In July 1995, the Board of Directors authorized an amendment to the
Plan, subject to stockholder approval, to increase the shares reserved for
issuance thereunder by 800,000 shares, bringing the total number of shares
issuable under the Plan to 1,200,000. At the Annual Meeting, the stockholders
are requested to consider and approve the proposed amendment to the Plan to
increase the number of shares issuable under the Plan to 1,200,000. The OXIS
Board believes that adoption of the amendment to the Plan will enable OXIS to
attract and retain the best available individuals to serve as employees,
officers, directors, consultants, independent contractors and advisors of OXIS.

SUMMARY OF THE PLAN

     The Plan permits granting stock options to acquire shares of OXIS' Common
Stock ("Options"), awarding stock bonuses of OXIS' Common Stock, selling shares
of OXIS' Common Stock and granting stock appreciation rights ("SARs")
(collectively, the "Awards"). Both incentive stock options ("ISOs") within the
meaning of section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), and nonqualified stock options "NQSOs") may be granted under the Plan.

     Awards under the Plan to other than directors of OXIS who are not employees
of either OXIS or a subsidiary of OXIS (the "Non-Employee Directors") are not
determinable because such awards are made in the discretion of the OXIS Board or
its designated committee. See "Administration" below.

                                       18
<PAGE>
 
PURPOSE

     The purposes of the Plan are to attract, retain and provide equity
incentives to selected persons to promote the financial success of OXIS. The
OXIS Board of Directors believes that it is essential to the future of OXIS that
OXIS be in a position to grant Awards under a stock incentive plan to selected
employees, officers, directors, consultants, independent contractors and
advisors in order for OXIS to remain competitive in attracting and retaining
such individuals.

ADMINISTRATION

     The Plan is administered by a committee of the Board of Directors of OXIS
(the "Plan Committee") comprised of at least two "disinterested persons" within
the meaning of Rule 16b-3(c)(2) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), although the plan could be administered by the
OXIS Board if it were comprised solely of "disinterested persons". The
interpretation and construction of any provision of the Plan or any related
agreement by the Plan Committee is final and binding. With the exception
discussed below in "Options - Non-Employee Director Formula Option Grants", the
Plan Committee selects the persons to whom Awards will be granted, determines
the type of Award, the number of shares to be covered by any Options or SARs
awarded, the exercise price of any such Options, the period during which any
such Options may be exercised and all other terms and conditions of Awards.

ELIGIBILITY

     With the exception discussed below in "Options - Non-Employee Director
Formula Option Grants", the Plan provides that awards may be granted to
employees, officers, directors, consultants, independent contractors and
advisors of OXIS or any parent, subsidiary or affiliate of OXIS. ISOs may be
granted only to employees (including officers and directors who are also
employees) of OXIS or any parent, subsidiary or affiliate of OXIS. See "Certain
United States Federal Income Tax Information" below for information concerning
the tax treatment of ISOs and NQSOs.

     As of July 19, 1995, there are eight directors of OXIS (six of whom are
Non-Employee Directors) and one OXIS officer (who is not a director) eligible to
participate in the Plan. There are approximately 67 employees of OXIS and its
subsidiaries who are not serving as officers who are also eligible to
participate. It is not possible to estimate the number of consultants,
independent contractors and advisors who are or may become eligible to
participate in the Plan.

OPTIONS

Grant of Options
- ----------------

     The date of grant of an Option is the date on which the Plan Committee
makes the determination to grant the Option unless otherwise specified by the
Plan Committee.  Option grants are evidenced by a written stock option

                                       19
<PAGE>
 
grant and, if for any reason a written stock option grant is not executed within
sixty (60) days of the date of grant, such Option grant shall be null and void.
No consideration shall be received by OXIS for the granting of Options. Subject
to the express provisions of the Plan, the exercise of an Option shall be
subject to such terms, conditions and restrictions as the Plan Committee may
impose in its sole discretion, including restrictions concerning
transferability, repurchase and forfeiture.

     Options shall be exercisable on the terms set forth in the stock option
grant; provided that no Option shall be exercisable after the expiration of ten
years from the Option grant date. The Plan Committee may accelerate the earliest
exercise date of any Option.

     The Plan states that there is a $100,000 limit to the aggregate fair market
value (calculated as set forth in "Option Price" below) of stock with respect to
which ISOs, whether granted under the Plan or any other ISO plan of OXIS or its
parent or subsidiary, are exercisable for the first time by an optionee during
any calendar year. The above limitations are driven by provisions of the Code
and are subject to change in the event that the relevant sections of the Code or
regulations promulgated thereunder are amended.

Option Price
- ------------

     The exercise price of a NQSO shall be not less than eighty-five percent
(85%) of the fair market value of the shares underlying the Option on the date
the Option is granted. The exercise price of an ISO shall be no less than one
hundred percent (100%) of the fair market value of the shares on the date the
Option is granted, unless the person to whom the Option is granted is a ten
percent (10%) shareholder of OXIS in which case the exercise price shall be not
less than one hundred ten percent (110%) of the fair market value of the shares
on the date the Option is granted. The Plan Committee shall have the power,
within certain limitations, to reduce the exercise price of outstanding Options.

     For purposes of the Plan, the fair market value of a share of OXIS' Common
Stock on a given date shall be the closing price on the NASDAQ National Market
System on the last trading day prior to the date of determination. The closing
price per share of OXIS' Common Stock on July 10, 1995, on the NASDAQ National
Market System was $3.00.

     The method of payment for shares issued upon exercise of Options granted
under the Plan shall be determined by the Plan Committee and may consist of
cash, cancellation of indebtedness, other shares of common stock and certain
other methods permitted by law.

Non-Employee Director Formula Option Grants
- -------------------------------------------

     No ISOs, SARs or stock bonuses shall be awarded or shares sold to Non-
Employee Directors under the Plan. All grants of Options to Non-Employee
Directors are automatic and nondiscretionary. Accordingly, no person shall have
any discretion to select which such Non-Employee Directors shall be granted
Options, to determine when such Options may be granted or to determine the
number of shares of OXIS' Common stock to be covered by Options granted to

                                       20
<PAGE>
 
such Non-Employee Directors. All grants of Options to such Non-Employee
Directors shall be made in strict accordance with the following provisions:

     (i)    On the first business day following OXIS Board approval of the Plan
(subject to stockholder approval of the Plan), each Non-Employee Director shall
receive a NQSO covering 15,000 shares. The OXIS Board approved the Plan on June
15, 1994 and the closing price per share of OXIS' Common Stock was $3.50. Non-
Employee Directors appointed by the OXIS Board or elected by the OXIS
stockholders after such date shall receive a NQSO covering 15,000 shares on the
first business day following such appointment or initial election. Thereafter,
annually on the first business day following the 1995 annual meeting of OXIS'
stockholders and the first business day following each annual meeting
thereafter, each Non-Employee Director (other than one taking office for the
first time as a result of his or her election at such meeting and therefore
receiving a NQSO covering 15,000 shares) shall receive a NQSO covering 5,000
shares.

     (ii)   The exercise price of such options shall be equal to one hundred
percent (100%) of the fair market value of the shares on the date of grant
determined as set forth under "Option Price" above.

     (iii)  Such options shall be exercisable beginning six months after the
date of the grant and their term shall be ten years.

STOCK BONUSES

     The Plan Committee may award shares under the Plan as stock bonuses for no
consideration or for such minimum consideration as may be required by applicable
law in an amount and form as determined by the Plan Committee. An award of a
stock bonus shall be subject to such terms, conditions and restrictions as the
Plan Committee may impose on its sole discretion, including restrictions
concerning transferability, repurchase and forfeiture. The recipient of a stock
bonus must also satisfy any applicable federal, state or local tax withholding
requirements.

STOCK SALES

     The Plan Committee may issue shares of OXIS Common Stock under the Plan for
such amount (no less than par value) and form of consideration as determined by
the Plan Committee. A stock sale under the Plan shall be subject to such terms,
conditions and restrictions as the Plan Committee may impose in its sole
discretion, including restrictions concerning transferability, repurchase or
forfeiture. The purchaser must also satisfy any applicable federal, state or
local tax withholding requirements.

STOCK APPRECIATION RIGHTS

     A SAR may be granted by the Plan Committee in tandem with an Option or as a
freestanding SAR.  No consideration shall be received by OXIS for the granting
of SARs. 

                                       21
<PAGE>
 
Subject to the express provisions of the Plan, the exercise of a SAR shall be
subject to such terms, conditions and restrictions as the Plan Committee may
impose at its sole discretion, including restrictions concerning
transferability, repurchase and forfeiture. The recipient of a SAR must also
satisfy any applicable federal, state or local tax withholding requirements.

     A SAR shall be exercisable only at the time or times established by the
Plan Committee; provided that no SAR shall be exercisable after the expiration
of ten years from the date the SAR was granted. If a SAR is granted in
connection with an Option, the SAR shall be exercisable only to the extent and
on the same conditions that the related Option could be exercised and, upon
exercise of such a SAR, any Option or any portion of such Option to which the
SAR relates shall terminate. Similarly, upon the exercise of an Option to which
a SAR relates, the SAR or portion thereof to which the Option relates shall
terminate.

     The Plan Committee may accelerate the earliest exercise date of any SAR.

NONASSIGNABILITY OF OPTIONS AND SARS

     Options and SARs granted pursuant to the Plan are nonassignable and
nontransferable by the optionee or recipient, other than by will or by the laws
of descent and distribution and may be exercised, during the lifetime of the
optionee or recipient, only by the optionee or recipient or any permitted
transferee.

ADJUSTMENT UPON CHANGES IN CAPITALIZATION AND CORPORATE TRANSACTIONS

     In the event that the number of outstanding shares of Common Stock of OXIS
is increased or decreased by a change in the capital structure of OXIS without
consideration, such as stock splits or dividends, or, if a substantial portion
of the assets of OXIS are distributed without consideration to the stockholders
of OXIS in a spin-off or similar transaction, appropriate adjustments shall be
made in the number or kind of shares available for Awards under the Plan, the
number or kind of shares subject to outstanding Options or SARs and the exercise
price per share of such Options.

     In the event of a merger, consolidation, or similar occurrence where OXIS
is not the surviving corporation, or the sale of all or substantially all of the
assets of OXIS, each outstanding Award shall be assumed or substituted by such
successor corporation. In the event such successor corporation does not agree to
assume or substitute such Awards or to provide substantially similar
consideration to optionees or other recipients of Awards as was provided to
stockholders, or in the event of a dissolution or liquidation of OXIS, OXIS
shall notify each optionee or other recipient that the Awards shall expire on a
date at least twenty (20) days after OXIS gives such written notice.

                                       22
<PAGE>
 
TERMINATION OF EMPLOYMENT OR SERVICE THROUGH DEATH, DISABILITY OR OTHERWISE

     Under the Plan, in the event an optionee ceases to be employed by or to
provide services to OXIS or any parent or subsidiary of OXIS (and, in the case
of a NQSO, by or to any affiliate of OXIS) for any reason other than death or
permanent and total disability, any Option which was exercisable at the date of
termination may thereafter be exercised for a period of thirty (30) days. If
termination results from death or permanent and total disability, any Option
which was exercisable at the date of termination may thereafter by exercised for
a period of twelve (12) months. However, in no event may any Option be exercised
once its term has expired.

PLAN AMENDMENT AND TERMINATION

     Except as described below, the Plan Committee may amend the Plan at any
time or may terminate the Plan without stockholder approval. However, except
with respect to SARs which may be withdrawn or amended at any time or may become
subject to retroactive rules and regulations, no action may be taken which would
impair the rights of any recipient of an Award without the consent of such
recipient, and the terms and conditions of formula grants to Non-Employee
Directors shall not be amended more frequently than permitted for formula plans
meeting the conditions of Rule 16b-3 promulgated by the SEC. In any event, the
Plan will terminate on April 30, 2004.

     Stockholder approval is required for certain specified amendments to the
Plan, including any amendment that increases the total number of shares for
which Awards may be granted, extends the duration of the Plan, extends the
period during and over which Options or SARs may be exercised under the Plan, or
changes the class of persons eligible to receive awards granted under the Plan
(except as may be required to comport with changes in the Code, ERISA or
regulations promulgated thereunder).

CERTAIN UNITED STATES FEDERAL INCOME TAX INFORMATION REGARDING OPTIONS

     Options granted under the Plan may be either ISOs, as defined in Section
422 of the Code, or NQSOs.

Incentive Stock Options
- -----------------------

     If an option granted under the Plan is an incentive stock option, the
optionee will recognize no income under the grant of the incentive stock option
and incur no tax liability at the time of exercise unless the optionee is
subject to the alternative minimum tax. OXIS will not be allowed a deduction for
federal income tax purposes as a result of the exercise of the incentive stock
option regardless of the applicability of the alternative minimum tax. Upon the
sale or exchange of the shares at least two years after the grant of the option
and one year after receipt of the shares by the optionee, any gain will be
treated as long-term capital gain. If these holding periods are not satisfied,
the optionee will recognize ordinary income equal to the difference between the
exercise price and the lower of the fair market value of the stock at the date
of option

                                       23
<PAGE>
 
exercise or the sale price of the stock. OXIS will be entitled to a deduction in
the same amount as the ordinary income recognized by the optionee.

Nonqualified Stock Options
- --------------------------

     All options which do not quality as incentive stock options under the Code
are referred to as nonqualifed stock options. Generally, an optionee will not
recognize any taxable income at the time the optionee is granted a nonqualified
stock option. However, upon exercise of the option, the optionee will recognize
ordinary income for income tax purposes equal to the excess of the then fair
market value of the shares over the option price. The income recognized by an
optionee who is also an employee of OXIS will be subject to tax withholdings by
OXIS by payment in cash or out of the current earnings paid to the optionee.
OXIS will be allowed a deduction for federal tax purposes in an amount equal to
the income recognized by the optionee so long as OXIS has met all applicable
withholding requirements and so long as the exercise of the option by optionee
does not cause OXIS to violate the limits on executive compensation set forth in
Section 162(m) of the Code. If the optionee holds such shares for more than one
year following exercise of the option, any gain realized upon disposition will
be treated as long-term capital gain. If the shares are sold within one year
after the exercise date, any gain realized upon disposition will be treated as
short-term capital gain. The gain realized upon disposition will be the excess,
if any, of the sales price over the tax basis of the shares.

Tax Summary Only
- ----------------

     The foregoing summary of the effect of federal income taxation upon the
optionee and OXIS with respect to the purchase of OXIS' shares under the Plan
does not purport to be complete, and reference should be made to the applicable
provisions of the Code. In addition, the summary does not discuss the provisions

                           1994 STOCK INCENTIVE PLAN



     1.   PURPOSE.  This 1994 stock incentive plan / ("plan") is established as
          -------                                                              
a compensatory plan to attract, retain and provide equity incentives to selected
persons to promote the financial success of ddi pharmaceuticals, inc., A
delaware corporation (the "company").  Capitalized terms not otherwise defined
herein are defined in section 21 of this plan.

     2.   TYPES OF AWARDS.  The Committee (as defined in Section 16 may, from
          ---------------                                                    
time to time, take the following actions under this Plan: (a) grant stock
options ("Options")  to acquire shares of the common stock, $0.50 par value, of
the Company ("Common Stock") as provided in Sections 5 and 6; (b) award stock
bonuses of Common Stock as provided in Section 8; (c) sell shares of the Common
Stock as provided in Section 9; or (d) grant stock appreciation rights ("SARs")
as provided in Section 10 (all of the foregoing shall be collectively referred
to as the "Awards").  Options granted under this Plan may be either (a)
incentive stock options ("ISOs") within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), or (b) nonqualified
stock options ("NQSOs"), as designated at the time of grant.  The shares of
stock that may be awarded, sold, purchased or acquired upon exercise of Options
or SARs granted under this Plan (the "Shares") are shares of Common Stock.

     3.   NUMBER OF SHARES.  The aggregate number of Shares that may be issued
          ----------------                                                    
under this Plan is 400,000 Shares, subject to adjustment as provided in this
Plan.  If any Option or SAR expires, is terminated or is cancelled without being
exercised in whole or in part, unissued Shares from such Option or SAR shall
again be available under this Plan.  Cash payments of SARs shall not reduce the
number of Shares reserved for issuance under this Plan.  If Shares sold or
awarded as a bonus under the Plan are forfeited to the Company, the number of
shares forfeited shall again be available under the Plan.  At all times during
the term of this Plan, the Company shall reserve and keep available such number
of Shares as shall be required to satisfy the requirements of outstanding
Options or SARs under this Plan.

     4.   ELIGIBILITY.
          ----------- 

          (a)  General Rules of Eligibility.  Awards may be granted to
               ----------------------------                           
employees, officers, directors, consultants, independent contractors and
advisors (provided such consultants, independent contractors and advisors render
bona fide services not in connection with the offer and sale of securities in a
capital-raising transaction) of the Company or any Parent, Subsidiary or
Affiliate of the Company.  ISOs may be granted only to employees (including
officers and directors who are also employees) of the Company or a Parent or
Subsidiary of the Company.  Awards may be granted to directors of the Company
who are not employees of either the Company or a Subsidiary (a "Non-Employee
Director") only pursuant to Section 6 of this Plan and in no event shall SARs or
stock bonuses be awarded or Shares sold to Non-Employee Directors under this
Plan.  The Committee in its sole discretion shall select the recipients of
<PAGE>
 
Awards ("Participants"), subject to the restrictions set forth in the
immediately preceding sentence.  A Participant may be granted more than one
Award under this Plan.

          (b)  Company Assumption of Awards.  The Company may also, from time to
               ----------------------------                                     
time, assume outstanding awards granted by another company, whether in
connection with an acquisition of such other company or otherwise, by either (i)
granting an Award under this Plan in replacement of the award assumed by the
Company, or (ii) treating the assumed award as if it had been granted under this
Plan if the terms of such assumed award could be applied to an award granted
under this Plan.  Such assumption shall be permissible if the holder of the
assumed award would have been eligible to be granted an award hereunder if the
other company had applied the rules of this Plan to such grant.

     5.   TERMS AND CONDITIONS OF OPTIONS.  The Committee shall determine
          -------------------------------                                
whether each Option (other than Options granted pursuant to Section 6 of this
Plan) is to be an ISO or an NQSO, the number of Shares subject to the Option,
the exercise price of the Option, the period during which the Option may be
exercised, and all other terms and conditions of the Option, subject to the
following:

          (a)  Form of Option Grant.  Each Option granted under this Plan shall
               --------------------                                            
be evidenced by a written Stock Option Grant (the "Grant") in substantially the
form attached hereto as Exhibit A or such other form as shall be approved by the
Committee.

          (b)  Date of Grant.  The date of grant of an Option shall be the date
               -------------                                                   
on which the Committee makes the determination to grant such Option unless
otherwise specified by the Committee and subject to applicable provisions of the
Code.  The Grant representing the Option will be delivered to the Optionee with
a copy of this Plan within a reasonable time after the date of grant; provided,
however, that with respect to Options other than Options granted pursuant to
Section 6 of this Plan if, for any reason, including a unilateral decision by
the Company not to execute an agreement evidencing such option, a written Grant
is not executed within sixty (60) days after the date of grant, such option
shall be deemed null and void.  No Option shall be exercisable until such Grant
is executed by the Company and the person receiving the Option (the "Optionee").

          (c)  Exercise Price.  The exercise price of an NQSO shall be not less
               --------------                                                  
than eighty-five percent (85%) of the Fair Market Value of the Shares on the
date the Option is granted.  The exercise price of an ISO shall be not less than
one hundred percent (100%) of the Fair Market Value of the Shares on the date
the Option is granted.  The exercise price of any ISO granted to a person owning
more than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any Parent or Subsidiary of the Company ("Ten Percent
Stockholders") shall not be less than one hundred and ten percent (110%) of the
Fair Market Value of the Shares on the date the Option is granted.

          (d)  Exercise Period.  Options shall be exercisable within the times
               ---------------                                                
or upon the events determined by the Committee as set forth in the Grant;
provided, however that no Option shall be exercisable after the expiration of
ten (10) years from the date the Option is granted, and 

                                      -2-
<PAGE>
 
provided further that no ISO granted to a Ten Percent Stockholder shall be
exercisable after the expiration of five (5) years from the date the Option is
granted.

          (e)  Limitations on Options.  The aggregate Fair Market Value
               ----------------------                                  
(determined as of the time an Option is granted) of stock with respect to which
ISOs are exercisable for the first time by an Optionee during any calendar year
(under this Plan or under any other incentive stock option plan of the Company
or any Parent or Subsidiary of the Company) shall not exceed one hundred
thousand dollars ($100,000).  To the extent that the Fair Market Value of stock
with respect to which ISOs are exercisable for the first time by an Optionee
during any calendar year exceeds $100,000, such Options shall be treated as
NQSOs.  The foregoing shall be applied by taking Options into account in the
order in which they were granted.  In the event that the Code or the regulations
promulgated thereunder are amended after the effective date of this Plan to
provide for a different limit on the Fair Market Value of Shares permitted to be
subject to ISOs, such different limit shall be incorporated herein and shall
apply to any Options granted after the effective date of such amendment.

          (f)  Options Non-Transferable.  Options granted under this Plan, and
               ------------------------                                       
any interest therein, shall not be transferable or assignable by the Optionee,
and may not be made subject to execution, attachment or similar process,
otherwise than by will or by the laws of descent and distribution and shall be
exercisable during the lifetime of the Optionee only by the Optionee or any
permitted transferee.

          (g)  Assumed Options.  In the event the Company assumes an option
               ---------------                                             
granted by another company in accordance with Section 4(b) above, the terms and
conditions of such Option shall remain unchanged (except the exercise price and
the number and nature of shares issuable upon exercise, which will be adjusted
appropriately pursuant to Section 424 of the Code and the Treasury Regulations
applicable thereto).  In the event the Company elects to grant a new Option
rather than assuming an existing option (as specified in Section 4), such new
Option need not be granted at Fair Market Value on the date of grant and may
instead be granted with a similarly adjusted exercise price.

          (h)  Restrictions on Shares.  At the discretion of the Committee, the
               ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Grant a right of
first refusal to purchase all Shares that an Optionee (or a subsequent
transferee) may propose to transfer to a third party.  The provisions of this
Section 5(h) shall not apply to any Option granted pursuant to Section 6 of this
Plan.

          (i)  Modification, Extension and Renewal of Options.  The Committee
               ----------------------------------------------                
shall have the power to modify, extend or renew outstanding Options and to
authorize the grant of new Options in substitution therefor, provided that any
such action may not, without the written consent of the Optionee, impair any
rights under any Option previously granted.  Any outstanding ISO that is
modified, extended, renewed or otherwise altered shall be treated in accordance
with Section 424(h) of the Code.  The Committee shall have the power to reduce
the exercise price of outstanding Options; provided, however, that the exercise
price per share may not be reduced below the minimum exercise price that would
be permitted under Section 5(c) of 

                                      -3-
<PAGE>
 
this Plan for Options granted on the date the action is taken to reduce the
exercise price. Notwithstanding any other provision of this Plan, the Committee
may accelerate the earliest date or dates on which outstanding Options (or any
installments thereof) are exercisable. The provisions of this Section 5(i) shall
not apply to Options granted pursuant to Section 6 of this Plan.

shall be evidenced by a written Stock Option Grant in substantially the form of
Exhibit A or such other form of Stock Option Grant as is approved by the
Committee and the Options are otherwise subject to the limitations of Section
5(f) of this Plan.

          (g)  Amendments.  Notwithstanding Section 18 of this Plan, the
               ----------                                               
provisions of this Section 6 shall not be amended more frequently than permitted
for formula plans meeting the conditions of Rule 16b-3 as promulgated by the
Securities and Exchange Commission ("Rule 16b-3").

     7.   EXERCISE OF OPTIONS.
          ------------------- 

          (a)  Notices.  Options may be exercised only by delivery to the
               -------                                                   
Company of a written exercise agreement in a form approved by the Committee
(which need not be the same for each Optionee), stating the number of Shares
being purchased, the restrictions imposed on the Shares, if any, and such
representations and agreements regarding the Optionee's investment intent and
access to information, if any, as may be required by the Company to comply with
applicable securities laws, together with payment in full of the exercise price
for the number of Shares being purchased.

          (b)  Payment.  Payment for the Shares may be made in cash (by check)
               -------                                                        
or, where approved by the Committee in its sole discretion at the time of grant
and where permitted by law:  (i) by cancellation of indebtedness of the Company
to the Optionee; (ii) by surrender of shares of Common Stock of the Company
already owned by the Optionee, having a Fair Market Value equal to the exercise
price of the Option; (iii) by waiver of compensation due or accrued to Optionee
for services rendered; (iv) provided that a public market for the Company's
stock exists, through a "same day sale" commitment from the Optionee and a
broker-dealer that is a member of the National Association of Securities
Dealers, Inc. (an "NASD Dealer") whereby the Optionee irrevocably elects to
exercise the Option and to sell a portion of the Shares so purchased to pay for
the exercise price and whereby the NASD Dealer irrevocably commits upon receipt
of such Shares to forward the exercise price directly to the Company; (v)
provided that a public market for the Company's stock exists, through a "margin"
commitment from the Optionee and an NASD Dealer whereby the Optionee irrevocably
elects to exercise the Option and to pledge the Shares so purchased to the NASD
Dealer in a margin account as security for a loan from the NASD Dealer in the
amount of the exercise price, and whereby the NASD Dealer irrevocably commits
upon receipt of such Shares to forward the exercise price directly to the
Company; or (vi) by any combination of the foregoing.  Payment of the exercise
price for Options granted pursuant to Section 6 shall be determined in
accordance with Section 6.

          (c)  Withholding Taxes.  Prior to issuance of the Shares upon exercise
               -----------------                                                
of an Option, the Optionee shall pay or make adequate provision for any federal
or state withholding obligations of the Company, if applicable.  Where approved
by the Committee in its sole discretion, the Optionee may provide for payment of
withholding taxes upon exercise of the Option by requesting that the Company
retain Shares with a Fair Market Value equal to the minimum amount of taxes
required to be withheld.  In such case, the Company shall issue the net number
of Shares to the Optionee by deducting the Shares retained from the Shares
exercised.  The Fair Market Value of the Shares to be withheld shall be
determined on the date that the amount of tax to be withheld is to be determined
in accordance with Section 83 of the Code (the "Tax Date").  All elections by
Optionees to have Shares withheld for this purpose shall be made in writing in a
form acceptable to the Committee and shall be subject to the following
restrictions:

     the election must be made on or prior to the applicable Tax Date;

                                      -5-
<PAGE>
 
     once made, the election shall be irrevocable as to the particular Shares as
to which the election is made;

     all elections shall be subject to the consent or disapproval of the
Committee;

     if the Optionee is an officer or director of the Company or other person
(in each case, an "Insider") whose transactions in the Company's Common Stock
are subject to Section 16(b) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act") and if the Company is subject to Section 16(b) of the
Exchange Act, the election must be made at least six (6) months prior to the Tax
Date and must otherwise comply with Rule 16b-3.

          (d)  Limitations on Exercise.  Notwithstanding anything else to the
               -----------------------                                       
contrary in the Plan or any Grant, no Option may be exercisable later than the
expiration date of the Option.

     8.   STOCK BONUSES.  The Committee may award Shares under the Plan as stock
          -------------                                                         
bonuses.  The certificates representing the Shares awarded shall bear any
legends required by the Committee.  The Company may award Shares as a stock
bonus to a Participant for no consideration or for such minimum consideration as
may be required by applicable law in an amount and form as determined by the
Committee.  The Company may also require any Participant receiving a stock bonus
to pay to the Company in cash upon demand amounts necessary to satisfy any
applicable federal, state or local tax withholding requirements.  If such
Participant fails to pay the amount demanded, the Company or any Parent or
Subsidiary of the Company may withhold that amount from other amounts payable to
such Participant by the Company or the Parent or Subsidiary, including salary,
subject to applicable law.  With the consent of the Committee and subject to
such requirements as may be imposed by the Committee (including the requirements
of Rule 16b-3, if applicable), a Participant may deliver Shares to the Company
to satisfy the withholding obligation.

     9.   STOCK SALES.  The Committee may issue Shares under the Plan for such
          -----------                                                         
amount and form of consideration as determined by the Committee; provided,
however, that in no event shall the consideration be less than the par value of
the Shares.  The certificates representing the Shares shall bear any legends
required by the Committee.  The Company may require any Participant purchasing
Shares issued under this Section 9 to pay to the Company in cash upon demand
amounts necessary to satisfy any applicable federal, state or local tax
withholding requirements.  If such Participant fails to pay the amount demanded,
the Company or any Parent or Subsidiary of the Company may withhold that amount
from other amounts payable to such Participant by the Company or any Parent or
Subsidiary of the Company, including salary, subject to applicable law.  With
the consent of the Committee and subject to such requirements as may be imposed
by the Committee (including the requirements of Rule 16b-3, if applicable), such
Participant may deliver Shares to the Company to satisfy the withholding
obligation.

     10.  STOCK APPRECIATION RIGHTS.
          ------------------------- 

          (a)  Grant.  SARs may be granted under this Plan in tandem with an
               -----                                                        
Option or as a freestanding SAR by the Committee, subject to such rules, terms
and conditions as the Committee prescribes.

          (b)  SARs Non-Transferable.  SARs granted under this Plan, and any
               ---------------------                                        
interest therein, shall not be transferable or assignable by the Participant
receiving such SARs, and may not be made subject to execution, attachment or
similar process, otherwise than by will or by the laws of descent and
distribution and shall be exercisable during the life of the Participant only by
the Participant or any permitted transferee.

          (c)  Modification, Extension and Renewal of SARs.  The Committee shall
have the power to modify, extend or renew outstanding SARs and to authorize the
grant of new SARs in substitution therefor, provided that any such action may
not, without the written consent of the Participant holding a SAR, impair any
rights under any SAR previously granted.  Notwithstanding any other provision of
this Plan, the Committee may accelerate the earliest date or dates on which
outstanding SARs (or any installments thereof) are exercisable.

          (d)  Exercise.  A SAR shall be exercisable only at the time or times
               --------                                                      
established by the Committee; provided, however, that no SAR shall be
exercisable after the expiration of ten (10) years from the date the SAR is
granted.  If a SAR is granted in connection with an Option, the SAR shall be
exercisable only to the extent and on the same conditions that the related
Option could be exercised.  Upon exercise of a SAR, any Option or portion
thereof to which the SAR relates shall terminate.  If a SAR is granted in
connection with an Option, upon exercise of the Option, the SAR or portion
thereof to which the Option relates shall terminate.

     The Committee may withdraw any SAR granted under this Plan at any time for
any reason or no reason whatsoever and may impose any terms, conditions, or
restrictions upon the exercise of a SAR or adopt rules and regulations from time
to time affecting the rights of holders of SARs.  Such rules and regulations may
govern the right to exercise SARs granted before adoption or amendment of such
rules and regulations as well as SARs granted thereafter.

     Each SAR shall entitle the holder, upon exercise, to receive from the
Company in exchange therefor an amount equal in value to the excess of the Fair
Market Value on the date of exercise of one Share over its Fair Market Value on
the date of grant (or, in the case of a SAR granted in connection with an
Option, the option exercise price per Share under the Option to which the SAR
relates), multiplied by the number of Shares covered by the SAR or the Option,
or portion thereof, that is surrendered.  No SAR shall be exercisable at a time
that the amount determined under this subsection is negative.  Payment by the
Company upon exercise of an SAR may be made in Shares valued at Fair Market
Value, in cash, or partly in Shares and partly in cash, all as determined by the
Committee.

     A fractional Share shall not be issued upon exercise of a SAR and any
fractions of a Share that would have resulted shall either be cashed out at Fair
Market Value or the number of 

                                      -7-
<PAGE>
 
Shares issuable under the SAR shall be rounded down to the nearest whole number,
as determined by the Committee.

     Each Participant who has exercised a SAR shall, upon notification of the
amount due, pay to the Company in cash amounts necessary to satisfy any
applicable federal, state or local tax withholding requirements.  If such
Participant fails to pay the amount demanded, the Company or any Parent or
Subsidiary of the Company may withhold that amount from other amounts payable to
such Participant by the Company or any Parent or Subsidiary, including salary,
subject to applicable law.  With the consent of the Committee and subject to
such requirements as may be imposed by the Committee (including the requirements
of Rule 16b-3, if applicable), a Participant may satisfy this obligation, in
whole or in part, by having the Company withhold from any Shares to be issued
upon the exercise that number of Shares that would satisfy the withholding
amount due or by delivering Shares to the Company to satisfy the withholding
amount.

     Upon the exercise of a SAR for Shares, the number of Shares reserved for
issuance under this Plan shall be reduced by the number of Shares issued.

     11.  PRIVILEGES OF STOCK OWNERSHIP.  No Participant receiving any Award
          -----------------------------                                     
under this Plan shall have any of the rights of a stockholder with respect to
any Shares until the date of issue to the Participant of a stock certificate for
such Shares.  No adjustment shall be made for dividends or distributions or
other rights for which the record date is prior to such date, except as provided
in this Plan.  The Company shall provide to each Optionee and each Participant
holding SARs a copy of the annual financial statements of the Company, at such
time after the close of each fiscal year of the Company as such statements are
released by the Company to its stockholders.

     12.  NO OBLIGATION TO EMPLOY; NO RIGHT TO FUTURE GRANTS.  Nothing in this
          --------------------------------------------------                  
Plan or any Award granted under this Plan shall confer on any Participant any
right (a) to continue in the employ of, or other relationship with, the Company
or any Parent or Subsidiary of the Company or limit in any way the right of the
Company or any Parent, Subsidiary or Affiliate of the Company to terminate the
Participant's employment or other relationship at any time, with or without
cause, or (b) to have any Award(s) granted to such Participant under this Plan,
or any other plan, or to acquire any other securities of the Company, in the
future.

     13.  ADJUSTMENT OF AWARD SHARES.  In the event that the number of
          --------------------------                                  
outstanding shares of Common Stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration, or
if a substantial portion of the assets of the Company are distributed, without
consideration in a spin-off or similar transaction, to the stockholders of the
Company, the number or kind of Shares available for Awards under this Plan, the
number or kind of Shares subject to outstanding Options or SARs and the exercise
price per Share of such Options, shall be proportionately adjusted, subject to
any required action by the Board or stockholders of the Company and compliance
with applicable securities laws; provided, 

                                      -8-
<PAGE>
 
however, that a fractional Share shall not be issued upon exercise of any Option
or SAR and any fractions of a Share that would have resulted shall either be
cashed out at Fair Market Value or the number of Shares issuable under the
Option or SAR shall be rounded down to the nearest whole number, as determined
by the Committee; provided further, that the exercise price may not be decreased
to below the par value, if any, for the Shares.

     14.  ASSUMPTION OF AWARDS BY SUCCESSORS.  In the event of (i) a merger or
          ----------------------------------                                  
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary or a Parent or where
there is no substantial change in the stockholders of the corporation and the
Awards granted under this Plan are assumed by the successor corporation), or
(ii) the sale of all or substantially all of the assets of the Company, any or
all outstanding Awards shall be assumed by the successor corporation, which
assumption shall be binding on all Participants, an equivalent Award shall be
substituted by such successor corporation or the successor corporation shall
provide substantially similar consideration to Participants as was provided to
stockholders (after taking into account the existing provisions of the
Participants' Awards such as the exercise price and the vesting schedule of
Options), and, in the case of outstanding shares subject to a repurchase option,
issue substantially similar shares or other property subject to repurchase
restrictions no less favorable to the Participant.

     In the event such successor corporation, if any, refuses to assume or
substitute, as provided above, pursuant to an event described in subsection (a)
above, or in the event of a dissolution or liquidation of the Company, the
Awards shall, notwithstanding any contrary terms in the Grant or other agreement
pertaining to any such Award, expire on a date specified in a written notice
given by the Committee to the Participants specifying the terms and conditions
of such termination (which date must be at least twenty (20) days after the date
the Committee gives the written notice).

     15.  ADOPTION AND STOCKHOLDER APPROVAL.  This Plan shall become effective
          ---------------------------------                                   
on the date that it is adopted by the Board. This Plan shall be approved by the
stockholders of the Company, in any manner permitted by applicable corporate
law, within twelve (12) months before or after the date this Plan is adopted by
the Board.  The Company will comply with the requirements of Rule 16b-3 (or its
successor) with respect to stockholder approval.  Options and SARs may be
granted under the Plan at any time after the date the Plan is adopted by the
Board, subject to Section 17.  However, no Option or SAR granted under this Plan
shall become exercisable until the Plan is approved by the stockholders, and all
grants under this Plan prior to such approval shall be conditioned on and
subject to such approval.  No Shares may be awarded as bonuses or sold under
this Plan until the Plan has been adopted by the Board and approved by the
stockholders of the Company pursuant to this Section 15.

     16.  ADMINISTRATION.  This Plan may be administered by the Board or a
          --------------                                                  
Committee appointed by the Board (the "Committee").  If all of the directors are
not Disinterested Persons, the Board shall appoint a Committee consisting of not
less than two directors, each of whom is a Disinterested Person and at all times
during which the Company is registered under the Exchange Act, the Committee
shall be comprised of Disinterested Persons.  As used in this Plan, references
to the "Committee" shall mean either such Committee or the 

                                      -9-
<PAGE>
 
Board if no committee has been established. The interpretation by the Committee
of any of the provisions of this Plan, any related agreements, or any Option or
SAR granted or other Award received pursuant to this Plan shall be final and
binding upon the Company and all persons having an interest in any Award or any
Shares purchased pursuant to an Option, stock sale or SAR or received pursuant
to any other Award. Subject to the express provisions of the Plan, the Committee
may impose any terms, conditions, and restrictions on Awards, including the
exercise of an Option or SAR, Shares awarded as a stock bonus, or Shares issues
under Section 9 of this Plan. The restrictions may include, without limitation,
restrictions concerning transferability, repurchase by the Company, and
forfeiture of the Shares issued, such as the type of restrictions set forth in
Section 5(h) of this Plan.

     17.  TERM OF PLAN.  Options or SARs may be granted pursuant to this Plan
          ------------                                                       
and stock bonuses may be awarded under this Plan and Shares may be sold under
this Plan from time to time on or prior to April 30, 2004, a date which is less
than ten years after the earlier of the date of approval of this Plan by the
Board or the stockholders of the Company pursuant to Section 15 of this Plan.

     18.  AMENDMENT OR TERMINATION OF PLAN.  The Board or Committee may, at any
          --------------------------------                                     
time, amend, alter, suspend or discontinue the Plan, but, except as provided in
Section 10(d)(ii) of this Plan, no amendment, alteration, suspension or
discontinuation shall be made which would impair the rights of any Participant
under any Award theretofore granted, without his or her consent, or which,
without the approval of the stockholders of the Company, would:

     except as provided in Section 13 of the Plan, increase the total number of
Shares reserved for the purposes of the Plan;

     extend the duration of the Plan;

     extend the period during and over which Options or SARs may be exercised
under the Plan; or

     change the class of persons eligible to receive Awards granted hereunder
(except as may be required to comport with changes in the Code, ERISA or
regulations promulgated thereunder).

Without limiting the foregoing, the Committee may at any time or from time to
time authorize the Company, with the consent of the respective Participants, to
issue new Awards in exchange for the surrender and cancellation of any or all
outstanding Awards.

     19.  APPLICABLE LAW AND REGULATIONS.  The obligations of the Company under
          ------------------------------                                       
this Plan are subject to the approval of state and federal authorities or
agencies with jurisdiction over the subject matter hereof.  The Company shall
not be obligated to issue or deliver Shares under this Plan if such issuance or
delivery would violate applicable state or federal securities laws, or if
compliance with such laws would, in the opinion of the Company, 

                                     -10-
<PAGE>
 
be unduly burdensome or require the disclosure of information which would not be
in the Company's best interests.

     20.  SECTION 16 CONSIDERATIONS.  With respect to persons subject to Section
          -------------------------                                             
16 of the Exchange Act, Awards granted or awarded under the Plan, the cash
settlement of SARs and the tax withholding provisions of this Plan are intended
to comply with all applicable conditions of Rule 16b-3 or its successors under
the Exchange Act.  To the extent any provision of this Plan or any action by the
Committee fails to so comply, any such provision or action shall be deemed null
and void to the extent permitted by law and deemed advisable by the Committee.
Persons subject to Section 16 of the Exchange Act are advised that there may be
considerations relevant to transactions they engage in with respect to the
Awards or the Shares (in addition to the provisions of the Plan or actions of
the Committee) which may determine whether such transactions comply with all
applicable conditions of Rule 16b-3 or its successors under the Exchange Act.
Such considerations may include, by way of example, restrictions on the exercise
of SARs during the first six (6) months following the date of grant and resales
of Shares acquired upon receipt of an Award or exercise of an Option.

     21.  CERTAIN DEFINITIONS.  As used in this Plan, the following terms shall
          -------------------                                                  
have the following meanings:

     "Parent" means any corporation (other than the Company) in an unbroken
chain of corporations ending with the Company if, at the time of the granting of
the Award, each of the corporations other than the Company owns stock possessing
fifty percent (50%) or more of the total combined voting power of all classes of
stock in one of the other corporations in such chain.

     "Subsidiary" means any corporation (other than the Company) in an unbroken
chain of corporations beginning with the Company if, at the time of the granting
of the Award, each of the corporations other than the last corporation in the
unbroken chain owns stock possessing fifty percent (50%) or more of the total
combined voting power of all classes of stock in one of the other corporations
in such chain.

     "Affiliate" means any corporation that directly, or indirectly through one
or more intermediaries, controls or is controlled by, or is under common control
with, another corporation, where "control" (including the terms "controlled by"
and "under common control with") means the possession, direct or indirect, of
the power to cause the direction of the management and policies of the
corporation, whether through the ownership of voting securities, by contract or
otherwise.

     "Disinterested Persons" shall have the meaning set forth in Rule 16b-
3(c)(2) as promulgated by the Securities and Exchange Commission under Section
16(b) of the Exchange Act, as such rule is amended from time to time and as
interpreted by the Securities and Exchange Commission.

     "Fair Market Value" shall mean the fair market value of the Shares as
determined by the Committee from time to time in good faith.  If a public market
exists for the Shares, the Fair Market Value shall be the average of the last
reported bid and asked prices for Common Stock of 

                                     -11-
<PAGE>
 
the Company on the last trading day prior to the date of determination or, in
the event the Common Stock of the Company is listed on a stock exchange or is a
Nasdaq National Market security, the Fair Market Value shall be the closing
price on such exchange or system on the last trading day prior to the date of
determination.

          ---------------------                                              
this Option shall terminate and may not be exercised if Optionee ceases to be
employed by, or provide services to, the Company or by any Parent or Subsidiary
of the Company (or, in the case of a nonqualified stock option, by or to any
Affiliate of the Company).  Optionee shall be considered to be employed by the
Company for all purposes under this Section 4 if Optionee is an officer,
director or full-time employee of the Company or any Parent, Subsidiary or
Affiliate of the Company or if the Committee determines that Optionee is
rendering substantial services as a part-time employee, consultant, contractor

The Committee shall have discretion to determine whether Optionee has ceased to
be employed by the Company or any Parent, Subsidiary or Affiliate of the Company

Date").

     5.   Termination Generally.  If Optionee ceases to be employed by the
          ---------------------

reason except death or disability, the Vested Options, to the extent (and only
to the extent) exercisable by Optionee on the Termination Date, may be exercised

<PAGE>
 
Termination Date; provided that this Option may not be exercised in any event
after the Expiration Date.

     6.   Death or Disability.  If Optionee's employment with the Company and
          -------------------                                                
all Parents, Subsidiaries and Affiliates of the Company is terminated because of

(and only to the extent) exercisable by Optionee on the Termination Date, may be
exercised by Optionee (or Optionee's legal representative), but only within
twelve (12) months after the Termination Date; and provided further that this
Option may not be exercised in any event later than the Expiration Date.

     7.   No Right to Employment.  Nothing in the Plan or this Grant shall
          ----------------------                                          
confer on Optionee any right to continue in the employ of, or other relationship
with, the Company or any Parent, Subsidiary or Affiliate of the Company or limit
in any way the right of the Company or any Parent, Subsidiary or Affiliate of
the Company to terminate Optionee's employment or other relationship at any
time, with or without cause.

     8.   Manner of Exercise.
          ------------------ 

          (a)  Exercise Agreement.  This Option shall be exercisable by delivery
               ------------------                                               
to the Company of an executed written Stock Option Exercise Agreement in the
form attached hereto as Exhibit 1, or in such other form as may be approved by
the Company, which shall set forth Optionee's election to exercise some or all
of this Option, the number of Shares being purchased, any restrictions imposed
on the Shares and such other representations and agreements as may be required
by the Company to comply with applicable securities laws.

          (b)  Exercise Price.  The Stock Option Exercise Agreement shall be
               --------------                                               
accompanied by full payment of the Exercise Price for the Shares being
purchased.  Payment for the Shares may be made in cash (by check), or, where
permitted by law, by any of the following methods approved by the Committee at
the date of grant of this Option, or for a grant pursuant to Section 6 of the
Plan as provided in Section 6 of the Plan, or any combinations thereof:

[_]  by cancellation of indebtedness of the Company to the Optionee;

[_]  by surrender of shares of Common Stock of the Company already owned by the
     Optionee, or which were obtained by Optionee in the open public market,
     having a Fair Market Value equal to the exercise price of the Option;

[_]  by waiver of compensation due or accrued to Optionee for services rendered;

[_]  provided that a public market for the Company's stock exists, through a
     "same day sale" commitment from the Optionee and a broker dealer that is a
     member of the National Association of Securities Dealers, Inc. (an "NASD
     Dealer") whereby the Optionee irrevocably elects to exercise the Option and
     to sell a portion of the Shares so purchased to pay for the exercise price
     and whereby the NASD Dealer irrevocably commits upon receipt of such Shares
     to forward the exercise price directly to the Company; or

                                     A - 3
<PAGE>
 
[_]  provided that a public market for the Company's stock exists, through a
     "margin" commitment from the Optionee and an NASD Dealer whereby the
     Optionee irrevocably elects to exercise this option and to pledge the
     Shares so purchased to the NASD Dealer in a margin account as security
     for a loan from the NASD Dealer in the amount of the exercise price, and
     whereby the NASD Dealer irrevocably commits upon receipt of such Shares
     to forward the exercise price directly to the Company.

     9.   Withholding Taxes.  Prior to the issuance of the Shares upon exercise
          -----------------                                                    
of this Option, Optionee must pay or make adequate provision for any applicable
federal or state withholding obligations of the Company.  The Optionee may
provide for payment of Optionee's minimum statutory withholding taxes upon
exercise of the Option by requesting that the Company retain Shares with a Fair
Market Value equal to the minimum amount of taxes required to be withheld, all
as set forth in Section 7(c) of the Plan.  In such case, the Company shall issue
the net number of Shares to the Optionee by deducting the Shares retained from
the Shares exercised.

     10.  Issuance of Shares.  Provided that such notice and payment are in form
          ------------------                                                    
and substance satisfactory to counsel for the Company, the Company shall cause
the Shares to be issued in the name of Optionee or Optionee's legal
representative.

     11.  Notice of Disqualifying Disposition of ISO Shares.  If the Option
          -------------------------------------------------                
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after exercise of the ISO with respect to the Shares to be sold or disposed
of, the Optionee shall immediately notify the Company in writing of such
disposition.  Optionee acknowledges and agrees that Optionee may be subject to
income tax withholding by the Company on the compensation income recognized by
the Optionee from any such early disposition by payment in cash or out of the
current wages or other earnings payable to the Optionee.

     12.  Nontransferability of Option.  This Option may not be transferred in
          ----------------------------                                        
any manner other than by will or by the law of descent and distribution and may
be exercised during the lifetime of Optionee only by Optionee or other permitted
transferee.  The terms of this Option shall be binding upon the executors,
administrators, successors and assigns of the Optionee.

     13.  Federal Tax Consequences.  Set forth below is a brief summary as of
          ------------------------                                           
the date this form of Option Grant was adopted of some of the federal tax
consequences of exercise of this Option and disposition of the Shares.  THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION
OR DISPOSING OF THE SHARES.

     14.  Exercise of ISO.  If this Option qualifies as an ISO, there will be no
          ---------------                                                       
regular federal income tax liability upon the exercise of this Option, although
the excess, if any, of the Fair Market Value of the Shares on the date of
exercise over the Exercise Price will be treated as 

                                     A - 4
<PAGE>
 
an adjustment to alternative minimum taxable income for federal income tax
purposes and may subject the Optionee to an alternative minimum tax liability in
the year of exercise.

     15.  Exercise of Nonqualified Stock Option.  If this Option does not
          -------------------------------------                          
qualify as an ISO, there may be a regular federal income tax liability upon the
exercise of the Option.  The Optionee will be treated as having received
compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the Fair Market Value of the Shares on the date of exercise over the
Exercise Price.  The Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

     16.  Disposition of Shares.  In the case of a nonqualified option, if
          ---------------------                                           
Shares are held for at least one year before disposition, any gain on
disposition of the Shares will be treated as long-term capital gain for federal
and California income tax purposes.  In the case of an ISO, if Shares are held
for at least one year after the date of exercise and at least two years after
the Date of Grant, any gain on disposition of the Shares will be treated as
long-term capital gain for federal and California income tax purposes.  If
Shares acquired pursuant to an ISO are disposed of within such one-year or two-
year periods (a "disqualifying disposition"), gain on such disqualifying
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the Fair Market Value of the
Shares on the date of exercise over the Exercise Price (the "Spread").  Any gain
in excess of the Spread shall be treated as capital gain.

     17.  Interpretation.  Any dispute regarding the interpretation of this
          --------------                                                   
Grant shall be submitted by Optionee or the Company to the Company's Board of
Directors or the Committee, which shall review such dispute at its next regular
meeting.  The resolution of such a dispute by the Board or Committee shall be
final and binding on the Company and Optionee.

     18.  Entire Agreement.  The Plan and the Stock Option Exercise Agreement
          ----------------                                                   
attached hereto as Exhibit 1 are incorporated herein by this reference.  This
Grant, the Plan and the Stock Option Exercise Agreement constitute the entire
agreement of the parties hereto and supersede all prior undertakings and
agreements with respect to the subject matter hereof.

upon exercise of this Option or disposition of the Shares and that Optionee
should consult a tax advisor prior to such exercise or disposition.

[_]  cash (check) in the amount of $         , receipt of which is acknowledged

<PAGE>
 
[_]  by delivery of a "margin" commitment from the Optionee and an NASD Dealer

     (this payment method may be used only if a public market for the Company's

[_]  The Company and Optionee hereby agree as follows:

     1.   Purchase of Shares.  On this date and subject to the terms and
          ------------------                                            
conditions of this Agreement, Optionee hereby exercises the Stock Option Grant
between the Company and Optionee dated as of the Date of Option Grant set forth
above (the "Grant"), with respect to the Number of Shares Purchased set forth
above of the Company's Common Stock (the "Shares") at an aggregate purchase
price equal to the Aggregate Purchase Price set forth above (the "Purchase
Price") and the Price per Share set forth above (the "Purchase Price Per
Share").  The term "Shares" refers to the Shares purchased under this Agreement
and includes all securities received (a) in replacement of the Shares, and (b)
as a result of stock dividends or stock splits in respect of the Shares.
Capitalized terms used herein that are not defined herein have the definitions
ascribed to them in the Plan or the Grant.

     2.   Representations of Purchaser.  Optionee represents and warrants to the
          ----------------------------                                          
Company that:

     Optionee has received, read and understood the Plan and the Grant and
agrees to abide by and be bound by their terms and conditions.

     Optionee is fully aware of (i) the highly speculative nature of the
investment in the Shares; (ii) the financial hazards involved; and (iii) the
lack of liquidity of the Shares [and the restrictions on transferability of the
Shares (e.g., that Optionee may not be able to sell or dispose of the Shares or
use them as collateral for loans)].

     Optionee is capable of evaluating the merits and risks of this investment,
has the ability to protect Optionee's own interests in this transaction and is
financially capable of bearing a total loss of this investment.]

     Optionee is purchasing the Shares for Optionee's own account for investment
purposes only and not with a view to, or for sale in connection with, a
distribution of the Shares within the meaning of the Securities Act of 1933, as
amended (the "1933 Act")].

     Optionee has no present intention of selling or otherwise disposing of all
or any portion of the Shares.]

     3.   Compliance with Securities Laws.  Optionee understands and
          -------------------------------                           
acknowledges that the Shares have not been registered under the 1933 Act and
that, notwithstanding any other 

                                      1-2
<PAGE>
 
provision of the Grant to the contrary, the exercise of any rights to purchase
any Shares is expressly conditioned upon compliance with the 1933 Act and all
applicable state securities laws. Optionee agrees to cooperate with the Company
to ensure compliance with such laws. The Shares are being issued under the 1933
Act pursuant to [the Company will check the applicable box]:

     Section 4(2) of the 1933 Act

     Other: .]

     4.   Federal Restrictions on Transfer.  (a) Optionee understands that the
          --------------------------------                                    
Shares must be held indefinitely unless they are registered under the 1933 Act
or unless an exemption from such registration is available and that the
certificate(s) representing the Shares will bear a legend to that effect.
Optionee understands that the Company is under no obligation to register the
Shares, and that an exemption may not be available or may not permit Optionee to
transfer Shares in the amounts or at the times proposed by Optionee.]

     5.   Rule 144.  Optionee has been advised that Rule 144 promulgated under
          --------                                                            
the 1933 Act, which permits certain resales of unregistered securities, requires
that a minimum of two (2) years elapse between the date of acquisition of Shares
from the Company or an affiliate of the Company and any resale under Rule 144.]

     6.   State Law Restrictions on Transfer.  Optionee understands that
          ----------------------------------                            
transfer of the Shares may be restricted by applicable state securities laws,
and that the certificate(s) representing the Shares may bear a legend or legends
to that effect.

     7.   Legends.  Optionee understands and agrees that the certificate(s)
          -------                                                          
representing the Shares will bear a legend in substantially the following form,
in addition to any other legends required by applicable law:

          "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933 (THE 'SECURITIES ACT'), AND MAY NOT BE OFFERED, SOLD
