       (hereinafter referred to as "Borrower"), and Bioxytech, which benefits
       from the Advance (as defined below), is a party to this Agreement for the
       purpose of guaranteeing its parent's obligations under this Agreement and
       agreeing to make available its assets as part of the Collateral
       (hereinafter defined) for the Advance; and

           WHEREAS, OXIS is in need of cash and the Lender, which obtains raw
       material supply from OXIS, is willing to accommodate OXIS on the terms
       and conditions of this Agreement; and

           WHEREAS, the parties are willing to enter into this Agreement with
       the understanding that if definitive supply and licensing agreements by
       and between OXIS and the Lender (hereinbelow provided for) are signed and
       delivered, the Advance hereunder shall constitute a credit in favor of
       the Lender, the same to be applied for offset under or in connection with
       said supply and licensing agreements.

           NOW, THEREFORE, in consideration of these premises and the further
       agreements of the parties hereinbelow set forth, the parties agree with
       each other as follows:

ARTICLE I     AMOUNTS AND TERMS OF THE ADVANCE

       SECTION 1.01       The Advance

       The Lender agrees, on the terms and conditions hereinafter set forth, to
make an Advance (the "Advance") to Borrower upon full execution and delivery of
this Agreement in an aggregate amount equal to U.S.$600,000.00. Not later than
2:00 P.M. (New York City time) on the date of the Advance and upon fulfillment

Advance available to Borrower in same day funds at the time and place as
instructed by OXIS.

                                      33

 
       SECTION 1.02  Interest and Repayment; Guaranty

       (a)  Borrower's Note.  Borrower shall repay, and shall pay interest on, 
            ---------------
the unpaid principal amount of the Advance made thereto in accordance with a
promissory note of Borrower, in substantially the form of Exhibit A hereto (the
"Note"), evidencing the indebtedness resulting from the Advance and delivered to
the Lender pursuant to Article II.

       (b)  Bioxytech Guaranty.  By signing this Agreement, Bioxytech, in
            ------------------
consideration of a portion of the loan proceeds being applied to its debts,
hereby unconditionally and absolutely guarantees, to the extent permitted by
French law, the full, faithful and timely performance of all of OXIS'
obligations (whether now or hereafter existing) under this Agreement (the
"Obligations"), including, without limitation, its obligation to repay the
Advance (with accrued interest, if any) as and when the same shall become due
and payable under the terms of this Agreement. Bioxytech also agrees, to the
extent permitted by French law, to pay any and all expenses (including, without
limitation, reasonable attorneys' fees and expenses) incurred by the Lender in
enforcing any rights under this Section 1.02(b). Without limiting the generality
of the foregoing, Bioxytech's liability shall extend to all amounts which
constitute part of the Obligations and would be owed by OXIS under this
Agreement and the Note but for the fact that they are unenforceable or not
allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving OXIS. Bioxytech guarantees, to the extent permitted by
French law, that the Obligations will be paid strictly in accordance with the
terms of this Agreement and the Note, regardless of any law, regulation or
order now or hereafter in effect in any jurisdiction affecting any of such terms
or the rights of the Lender with respect thereto. The obligations of Bioxytech
under this Section 1.02(b) are independent of the Obligations, and a separate
action or actions may, subject to the foregoing, be brought and prosecuted
against Bioxytech to enforce this guaranty, irrespective of whether any action
is brought against the Borrower or whether the Borrower is joined in any such
action or actions. The liability of Bioxytech under this guaranty shall be
absolute and unconditional, to the extent permitted under French law,
irrespective of:

            (i)   any lack of validity or enforceability of this Agreement, the
       Note or any other agreement or instrument relating thereto;

            (ii)  any change in the time, manner or place of payment of, or in
       any other term of, all or any of the Obligations, or any other amendment
       or waiver of or any consent to departure from this Agreement or the Note,
       including, without limitation, any increase in the Obligations resulting
       from the extension of additional credit to the Borrower or any of its
       subsidiaries or otherwise;

            (iii) any taking, exchange, release or non-perfection of any
       collateral, or any taking, release or amendment or waiver of or consent
       to departure from any other guaranty, for all or any of the Obligations;

            (iv)  any manner of application of collateral, or proceeds thereof,
       to all or any of the Obligations, or any manner of sale or other
       disposition of any Collateral for all or any of the Obligations or any
       other assets of the Borrower or any of its subsidiaries;

            (v)   any change, restructuring or termination of the corporate 
       structure or existence of the Borrower or any of its subsidiaries; or

                                      34

 
            (vi)  any other circumstances which might otherwise constitute a 
       defense available to, or a discharge of, the Borrower or a guarantor.

This guaranty shall, to the extent permitted under French law, continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Obligations is rescinded or must otherwise be returned by the Lender
upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise,
all as though such payment had not been made. Bioxytech hereby waives
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Obligations and this guaranty and any requirement that the Lender
protect, secure, perfect or insure any security interest or lien or any property
subject thereto or exhaust any right or take action against the Borrower or any
other person or entity or any collateral.

       SECTION 1.03       Optional Prepayments

       Borrower may prepay the outstanding principal amount of the Advance made
thereto in whole or in part, together with accrued interest (if any is due) to
the date of such prepayment on the principal amount prepaid; provided, however,
                                                             --------  -------
that each partial prepayment shall be in a principal amount not less than
$25,000.

       SECTION 1.04       Payments and Computations

       Borrower shall make payment hereunder and under any other Loan Document
(as hereinafter defined) not later than 2:00 P.M. (New York City time) on the
day when due in lawful money of the United States of America to the Lender c/o
Sanofi, Inc., 90 Park Avenue, New York, New York 10016 in same day funds or as
otherwise agreed by the Lender and Borrower. All computations of interest under
the Note shall be made by the Lender on the basis of the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest is payable. Each determination by the Lender of an interest
rate hereunder shall be conclusive and binding for all purposes, absent
manifest error.

                                PROMISSORY NOTE

$600,000                                                     Dated:  May 4, 1995

       FOR VALUE RECEIVED, the undersigned, OXIS International, Inc., a Delaware
corporation (the "Borrower"), HEREBY PROMISES TO PAY to the order of Sanofi
S.A. (the "Lender") the principal sum of U.S.$600,000 on the date which is one
year from this date. The Borrower shall pay interest on the principal amount
hereof from time to time outstanding after the earlier to occur of (a) the date
six months from this date, or (b) the date of the first occurrence of an Event
of Default (as defined in the Loan Agreement), until such principal amount is
paid in full. Interest shall be payable on the final day when such principal
amount becomes due, at a fluctuating interest rate per annum in effect from
time to time equal at all times to 2% per annum (4% per annum from and after
said Event of Default) above the rate of interest announced publicly by
Citibank, N.A., in New York, New York, from time to time as its prime rate (the
"Prime Rate"). Each change in the fluctuating interest rate hereunder shall take
effect simultaneously with the corresponding change in the Prime Rate.

       Both principal and interest are payable in lawful money of the United
States of America to the Lender c/o Sanofi, Inc., 90 Park Avenue, New York, New
York 10016, in same-day funds or as otherwise agreed by the Lender and the
Borrower. All payments made on account of the principal amount hereof shall be
recorded by the Lender and, prior to any transfer hereof, endorsed on the grid
attached hereto which is part of this Promissory Note.

       This Promissory Note is the Note referred to in, and is entitled to the
benefits of, the Term Loan Agreement, dated as of May 2, 1995 (the "Loan
Agreement"), between the Borrower, Bioxytech S.A., and the Lender, and the
Security Agreement (as defined in the Loan Agreement). The Loan Agreement, among
other things, contains provisions for acceleration of the maturity hereof upon
the happening of certain stated events and also for prepayments on account of
principal hereof prior to the maturity hereof upon the terms and conditions
therein specified.
