Effective as of 3-1-93 THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR
UNIVERSITY, a body having corporate powers under the laws of the State of
California (STANFORD), and CALYPTE BIOMEDICAL CORPORATION a California
corporation having a principal place of business at 1440 Fourth Street,
Berkeley, CA  94710 (LICENSEE) agree as follows

                                 1.  BACKGROUND

   1.1--In the course of fundamental research programs at the University of
California and STANFORD (Universities), inventions were conceived jointly which
relate to engineering biologically functional replicons possessing desired
genetic properties of parent DNA molecules.  These research programs were
supported by the National Science Foundation, the American Cancer Society, and
the National Institutes of Health of the Department of Health, Education and
Welfare, now Health and Human Services (HHS).  These agencies and the
Universities agreed that the intellectual property rights resulting from these
inventions (and licensed through this Agreement) would be administered pursuant
and subject to the terms of STANFORD's Institutional Patent Agreement (IPA)
with HHS.

   1.2--The Universities have agreed that Stanford will manage the securing of
patent rights and licensing in the public interest, and that any net income
arising therefrom will be shared between the Universities, and designated to be
used for educational and research purposes.

   1.3--By assignment of the inventions from the inventors, STANFORD is the
owner of certain U.S. Patent rights and desires to grant licenses under those
rights to licensees for development of products and processes for public use
and benefit.

   1.4--LICENSEE desire to develop processes and methods and marketable
products for public use and benefit by using Licensed Patent Rights, and it
will follow good safety practices in such development work.

results in its destruction or loss of activity and/or loss of value.

   2.3--Licensed Product(s) means materials (including organisms) which, in the
course of manufacture, use, or sale would, in the absence of this license,
infringe one or more claims of Licensed Patent Rights which have not been held
invalid by a court from which no appeal may be taken.

   Four categories of Licensed Products are designated:

         End Products (Paragraph 2.4)
         Basic Genetic Products (Paragraph 2.5)
         Process Improvement Products (Paragraph 2.6)
         Bulk Products (Paragraph 2.7)

   2.4--End Products means marketable goods having at least one component

are sold in a form for utilization by the Ultimate Consumer, and are not
intended or marketed for further information, processing, or chemical
transformation, illustrative End Products include:

         (a)     health care products, sold for patient care and use or
                 dispensation by medical professionals (for example, dosage
                 forms of hormones, vaccines, and biosynthesized drugs, films,
                 fibers or dressings; and reagents or devices used for
                 diagnostic purposes, incorporating biochemical agents such as
                 antibodies, enzymes, specific binding proteins or
                 polysaccharides);

         (b)     products sold in a form ready for application to seeds, for
                 addition to feed or crop treating agents, for administration

         (c)     microorganisms and/or their products which are suitable for
                 use as animal or human food, for degrading substances in an
                 environment, or for increasing the production of desired
                 substances (such as concentrating minerals, generating gas or
                 useful compost from low value substrates);

    product falling under Basic Genetic Products (paragraph 6.6.1), Bulk
    Products (paragraphs 6.6.2) or Process Improvement Products (paragraph
    6.6.3) are greater than the royalties that would result if calculated on
    the End Product (for sales in the U.S. and other territories) made from or

    shall consider such factors as the size of the potential market for the
    Licensed Product(s) involved the anticipated profit margin, the royalty
    rates for End Products, the royalty that would be paid on the End Products
    most likely to be prepared for the Ultimate Consumer from the Licensed
    Product(s) in question and prevailing royalty rates in the industry to
    which the Licensed Product(s) pertain.

and identify such Affiliate or other licensee.
