         FOR VALUE RECEIVED, GOLDEN PHARMACEUTICALS, INC., a corporation
    organized and existing under the laws of the State of Colorado and QUALITY

    Agreement, at the interest rates provided therein. Such interest shall be

         Interest shall be calculated on the basis of a three hundred sixty
    (360) day year and actual days elapsed. In no event shall the interest
    charged hereunder exceed the maximum permitted under the laws of the State
    of California or other applicable law.

         This Note evidences the aggregate outstanding principal balance, from
    time to time, of the Revolving Loans made by Payee to Debtor pursuant to the
    Loan Agreement, the aggregate principal amount of which at any one time
    outstanding Payee intends not to exceed the Maximum Credit. It is
    contemplated that there may be times when no indebtedness is owing
    hereunder; but notwithstanding any such occurrence or occurrences, this Note
    shall remain valid and shall be in full force and effect as to the Revolving
    Loans made subsequent to each such occurrence.

         This Note is secured by the Collateral described in the Loan Agreement
    and all guarantees, security agreements and other agreements, documents and
    instruments now or at any time hereafter executed and/or delivered by
    Debtor, any guarantor or any other party in connection therewith (all of the
    foregoing, together with the Loan Agreement, as the same now exist or may
    hereafter be amended, modified, supplemented, renewed, extended, restated or
    replaced, being collectively referred to herein as the "Financing
    Agreements"), and is entitled to all of the benefits and rights thereof and
    of the other Financing Agreements. At the time any payment is due hereunder,
    at its option, Payee may charge the amount thereof to any account of Debtor
    maintained by Payee.

         If any payment of principal or interest is not made when due hereunder,
    of if any other default or Event of Default shall occur for any reason, or
    if the Loan Agreement shall be terminated for any reason whatsoever, then
    and in any such event, in addition to all rights and remedies of Payee under
    the Financing Agreements, applicable law or otherwise, all such rights and
    remedies being cumulative, not exclusive and enforceable alternatively,
    successively and concurrently, any or all of Debtor's obligations,
    liabilities and indebtedness owing under the Loan Agreement and the other
    Financing Agreements (the "Obligations"), including, without limitation, all
    amounts owing under this Note, may, as provided in the Loan Agreement, be
    declared or shall forthwith become due and payable, together with all
    interest accrued thereon and with interest accruing thereafter at the then
    applicable interest rate under the Loan Agreement until the indebtedness
    evidenced by this Note is paid in full, plus the costs and expenses of
    collection hereof, including, but not limited to, reasonable attorneys' fees
    and legal expenses.

         Debtor (i) waives diligence, demand, presentment, protest and notice of
    any kind, (ii) agrees that it will not be necessary to first institute suit
    in order to enforce payment of this Note and (iii) consents to any one or
    more extensions or postponements of time of payment, release, surrender or

    Agreement, Payee, shall have the right, subject to the terms of the Loan
    Agreement, but not the obligation, to set off against this Note all money
    owed by Payee to Debtor.

         No resort to any Collateral for payment shall be required prior to the
    enforcement hereof against Debtor and any guarantors or endorsers hereof.
    None of the rights of Payee shall be waived or diminished by any failure or
    delay in the exercise thereof.

    DEALINGS OF DEBTOR AND PAYEE WITH RESPECT TO THIS NOTE OR ANY OTHER
    INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION
    HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER
    NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT
    OR OTHERWISE, AND DEBTOR HEREBY CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION
    OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT
    DEBTOR OR PAYEE MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS PARAGRAPH
    WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE PARTIES HERETO TO
    THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

    or provision of the Loan Agreement, such term or provision of the Loan
    Agreement shall control.

         This Note shall be governed by and construed in accordance with the
    laws of the State of California applied to contracts to be performed wholly
    within the State of California.
