ITEM 1.  BUSINESS


COMPANY BACKGROUND

         Protein Polymer Technologies, Inc., a Delaware corporation ("PPTI" or
"the Company"), is a development-stage biotechnology company incorporated on
July 6, 1988 and is engaged in the research, development, production and
clinical testing of medical products based on its proprietary protein-based
biomaterials technology. Since 1992, the Company has focused primarily on
developing materials technology and products to be used in the surgical repair
of tissue: surgical adhesives and sealants; soft tissue augmentation products;
wound healing matrices; drug delivery devices; and surgical adhesion barriers.
The Company has also developed coating technology that can efficiently modify
and improve the surface properties of more traditional biomedical devices. A
common goal is to develop materials that beneficially interact with human cells,
enabling cell growth and the regeneration of tissues with improved outcomes as
compared to current products and practices.

         In December 1999, the Company initiated human clinical testing of its
urethral bulking agent for the treatment of female stress urinary incontinence.
The August 1999 approval by the U.S. Food and Drug Administration ("FDA") of the
Company's Investigational Device Exemption ("IDE") allows PPTI to test the
safety and effectiveness of the incontinence product in women over the age of 40
who have become incontinent due to the shifting of their bladder or the
weakening of the muscle at its base that controls the flow of urine, or both
problems combined. The Company estimates that more than 2.5 million women begin
to experience stress urinary incontinence in the United States each year. In
most untreated cases, the problem becomes progressively more pronounced. Due to
limited efficacy or invasiveness of current treatments, only a small proportion
of the women experiencing stress urinary incontinence are clinically treated,
relying instead on pads and plugs and the like that only address the symptoms.
In contrast, PPTI's product is injected, typically in an out patient procedure,
into urethral tissue at the base of the bladder forming a solid implant that
provides support to the muscles controlling the flow of urine. The Company
believes that its product will prove to be easy for the physician to use, offer
enduring effectiveness, and avoid most of the other limitations of urethral
bulking products on the market or in development.

         The tissue augmentation materials and technology underlying the
incontinence product have the potential to be effective and desirable in a
number of other clinical applications. The Company intends to submit an
additional IDE to the FDA in 2000 to obtain approval to begin human clinical
testing of its dermal bulking agent for use in cosmetic and reconstructive
surgery applications. PPTI began studies to identify its most promising
biomaterial formulations for use in these soft tissue augmentation products in
1996, devoted increasing resources through 1997 and 1998, and has primarily
focused on this program area in 1999 in preparation for human clinical testing.

                                       2
<PAGE>

         In January 2000, PPTI established a strategic alliance with Femcare,
Ltd. ("Femcare") for the commercialization of the incontinence product in Europe
and Australia. In the agreement, Femcare is responsible for clinical testing,
regulatory approval, and product sales and marketing within these territories,
and PPTI is responsible for product manufacturing. Contingent on successful
clinical trials commercialization of the product in Europe is expected to begin
more than a year before approval for marketing the product in the United States
can be obtained. PPTI also is in discussions with several companies regarding
the establishment of strategic alliances for commercializing the incontinence
product in the United States and other markets outside the Femcare territories.

         Between 1994 and 1997, the Company's efforts were focused predominantly
on the development of its surgical adhesive and sealant technology. As part of
this effort, the Company targeted the establishment of a strategic alliance with
a market leader in the field of surgical wound closure products which lead to
the execution of comprehensive license, supply and development agreements in
September 1995, with Ethicon, Inc. ("Ethicon"), a subsidiary of the Johnson &
Johnson Company ("J&J"). Ethicon elected to terminate these agreements in
December 1997.

         The Company has demonstrated both the adhesive performance and the
biocompatibility of its product formulations in animal models, including the
resorption of the adhesive matrix in conjunction with the progression of wound
healing. PPTI is committed to the commercial development of its adhesive and
sealant technology. Subsequent to the termination of the Ethicon agreement, the
Company has worked to determine the most significant market and product
opportunities for its use. PPTI is seeking to establish new strategic alliances
with leaders in those markets.

         To the extent sufficient resources are available, the Company continues
to research the use of its protein polymers for other tissue repair and medical
device applications, principally for use in tissue engineering matrices and drug
delivery devices.

         Through 1999, PPTI marketed specialty use products for in vitro cell
                                                                --------
culture applications including SmartPlastic(R) and ProNectin(R) F Cell
Attachment Factor. ProNectin F was launched commercially in 1991. SmartPlastic
is ProNectin F Activated Cultureware where ProNectin F is presented in ready to
use form on the surfaces of disposable plastic labware for culturing human and
animal cells. SmartPlastic was launched commercially in 1995. In 1998 the
Company discontinued direct sales of its cell culture products, and in February
2000, the Company sold all rights to the use of the technology for in vitro cell
                                                                   --------
culture applications, the product trademarks, and remaining inventory to Sanyo
Chemical Industries, Ltd.

         Prior to 1992, the Company's scientists had successfully demonstrated
the ability to create and produce novel protein polymer materials having
important physical, biological and chemical properties. During this period, most
of the Company's efforts were dedicated to supplying E. I. DuPont de Nemours &
Co. ("DuPont") with materials under contract for its proprietary research and
testing purposes.

                                       3
<PAGE>

         In 1992, the Company raised approximately $8.9 million through its
initial public offering of common stock and redeemable warrants. The Company
used a major portion of these proceeds to generate substantive in vitro
                                                               --------
laboratory evidence and in vivo animal test data demonstrating the
                        -------
biocompatibility and performance of its protein polymers and derived
biomaterials, and to establish a materials science group which has developed
important materials modification and fabrication technology.

         In July 1994, the Company raised approximately $2.1 million from the
sale of its unregistered Series C Preferred Stock to private investors. In
September 1995, the Company raised approximately $2.4 million from the sale of
its unregistered Series D Preferred Stock to the same private investors. Also at
this time these investors exchanged all of their holdings of Series C Preferred
Stock and accumulated dividends into Series D Preferred Stock. In January 1997,
the Company raised approximately $4.6 million from a private placement of the
Company's common stock with a number of institutional and accredited investors.

         In April and May 1998, the Company raised approximately $5.4 million
from the private sale of the Company's Series E Convertible Preferred Stock and
warrants to a small group of institutional and accredited investors. In
connection with this transaction, the Company also issued shares of Series F
Convertible Preferred Stock in exchange for the same number of shares of
outstanding Series D Convertible Preferred Stock.

         During April 1999, the Company received approximately $508,000 from the
exercise of redeemable, publicly traded warrants originally issued as part of
PPTI's Initial Public Offering, and during May 1999 the Company received
approximately $416,000 for the conversion of warrants issued in conjunction with
its private placement of Series E Convertible Preferred Stock. In August and
September of 1999, the Company received approximately $2 million, net of costs,
from a private placement of its Series G Convertible Preferred Stock priced at
$100 per share with warrants to purchase an aggregate of 4,200,000 shares of
common stock to a small group of institutional and accredited investors.

         The Company's cash balance as of December 31, 1999 was $156,000. The
Company believes this amount, in combination with approximately $3.4 million in
revenues and receivables obtained in January and February 2000 from licensing
and R&D agreements, and the exercise of common stock warrants issued in
connection with Series G Convertible Preferred Stock, is sufficient to fund its
operations through January 2001. Beyond this fiscal year, we believe there are a
number of alternatives available to meet our continuing capital requirements.
See the Liquidity and Capital Resources section of Management's Discussion and
Analysis of Financial Condition and Results of Operations for further
discussion.

THE COMPANY'S TECHNOLOGY

         PPTI is focused on developing products to improve medical and surgical
outcomes, based on an extensive portfolio of proprietary biomaterials.
Biomaterials are materials that are used to direct, supplement, or replace the
functions of living systems. The interaction between materials

                                       4
<PAGE>

and living systems is dynamic. It involves the response of the living system to
the materials (e.g., biocompatibility) and the response of the materials to the
living system (e.g., degradation). The requirements for performance within this
demanding biological environment have been a critical factor in limiting the
myriad of possible metal, polymer, and ceramic compositions to a relatively
small number that to date have been proven useful in medical devices.

         The goal of biomaterials development historically has been to produce
inert materials -- materials that elicit little or no response from the living
system. However, the Company believes that such conventional biomaterials are
constrained by their inability to convey appropriate messages to the cells that
surround them -- the same messages that are conveyed by proteins in normal human
tissues.

         The products targeted for development by PPTI are based on a new
generation of biomaterials which have been designed to be recognized and
accepted by human cells, to aid in the natural process of bodily repair
(including the healing of tissue and the restoration or augmentation of its form
and function), and, ultimately, to promote the regeneration of tissues. The
Company believes that the successful realization of these properties will
substantially expand the role that artificial devices can play in the prevention
and treatment of human disability and disease, and enable the culture of native
tissues for successful reimplantation.

         Through its proprietary core technology, PPTI produces high molecular
weight polymers that can be processed into a variety of material forms such as
gels, sponges, films, and fibers, with their physical strength and rate of
resorption tailored to each potential product application. These polymers are
constructed of the same amino acids as natural proteins found in the body. The
Company has demonstrated that its polymers can mimic the biological and chemical
functions of natural proteins and peptides, such as the attachment of cells
through specific membrane receptors and the ability to participate in enzymatic
reactions, thus overcoming a critical limitation of conventional biomaterials.
In addition, materials made from PPTI's polymers have demonstrated excellent
biocompatibility in a variety of preclinical feasibility studies.

         PPTI's patented core technology enables messages that direct activities
of cells to be precisely formulated and presented in a structured environment
similar to what nature has demonstrated to be essential in creating, maintaining
and restoring the body's functions. The Company's protein polymers are made by
combining the techniques of modern biotechnology and traditional polymer
science. The techniques of biotechnology are used to create synthetic genes that
direct the biological synthesis of protein polymers in recombinant
microorganisms. The methods of traditional polymer science are used to design
novel materials for specific product applications by combining the properties of
individual "building block" components in polymer form.

         In contrast to natural proteins, either isolated from natural sources
or produced using traditional genetic engineering techniques, PPTI's technology
results in the creation of new proteins with unique properties. PPTI has
demonstrated its capability to create materials that:

          .    combine properties of different proteins found in nature;

                                       5
<PAGE>

          .    reproduce and amplify selected activities of natural proteins;

          .    eliminate undesired properties of natural proteins; and

          .    incorporate synthetic properties via chemical modifications.

         This capability is fundamental to PPTI's current primary product
research and development focus -- tissue repair and regeneration. Tissues are
highly organized structures made up of specific cells arranged in relation to an
extracellular matrix ("ECM"), which is principally composed of proteins. The
behavior of cells is determined largely by their interactions with the ECM.
Thus, the ability to structure the cells' ECM environment allows the protein
messages they receive -- and their activity -- to be controlled. Similar to what
nature has demonstrated to be essential in creating, maintaining and restoring
the body's functions, PPTI's patented core technology enables messages that
direct activities of cells to be precisely formulated and presented in a
structured environment.

FUNDAMENTAL PROTEIN POLYMERS

         PPTI's primary products under development are based on protein polymers
combining selected properties from two of the most extraordinary structural
proteins found in nature: silk and elastin. Silk, based upon its crystalline
structure, has long been known as an incredibly strong material, and has a long
history of medical use in humans as a material for sutures. Elastin fibers are
one of the most remarkable rubber-like materials ever studied. Found in human
tissues such as lungs and arteries, elastin fibers must expand and contract over
a life time, and can be extended nearly three times their resting length without
damaging their flexibility.

         Despite the incredible individual properties of silk and elastin,
neither of these natural protein materials is capable of being processed into
forms other than what nature has provided without destroying their valuable
materials properties. However, PPTI's proprietary technology has enabled the
creation of polymers that combine the repeating blocks of amino acids
responsible for the strength of silk and the elasticity of elastin. By precisely
varying the number and sequence of the different blocks in the assembled protein
polymer, new combinations of properties suitable for various medical
applications have been created.

         The Company has also created protein polymers based on repeating blocks
of amino acids found in two other classes of structural proteins found in
nature: collagen and keratin. Collagen is the principal structural component of
the body, found in some shape or form in virtually every tissue, ranging from
shock absorbing cartilage to light transmitting corneas. Keratin is a major
component in hair, nails and skin. The development of materials based on these
polymers is at an early stage of research.

PRODUCT CANDIDATES AND ANTICIPATED MARKETS

         The Company's technology and materials have the potential to create
products and product applications in a variety of medical and specialty use
markets. The Company's current development efforts are principally focused on
preparations for scale-up and validation of manufacturing processes for its
hydrogel bulking agents for soft tissue augmentation. However,

                                       6
<PAGE>

opportunities for research and development of product candidates for other
medical and specialty use continue to be evaluated, particularly those based on
its tissue adhesive and sealant technology.

         All of the Company's product candidates are subject to preclinical and
clinical testing requirements for obtaining U.S. Food and Drug Administration's
("FDA's") marketing approval. The actual development of other product
candidates, if any, will depend on a number of factors, including the
availability of funds required to research, develop, test and obtain necessary
regulatory approvals; the anticipated time to market; the potential revenues and
margins that may be generated if a product candidate is successfully developed
and commercialized; and the Company's assessment of the potential market
acceptance of a product candidate.

         Soft Tissue Augmentation

         Conditions where there is a need to augment the body's soft tissues
include both cosmetic and medical applications. In the former, for example,
current procedures include the injection of collagen-based materials to smooth
out facial wrinkles, acne scars and to modify lip contours. However, these
treatments only last a matter of months, which puts them economically out of
reach for a large portion of the population of people who would otherwise desire
the procedure.

         Medical applications include the treatment of stress urinary
incontinence, gastroesophageal reflux, and fecal incontinence, the reversible
blockage of fallopian tubes for birth control, the augmentation of vocal chords,
and the expansion of gingival tissues impacted by periodontal disease. PPTI
believes there is a lack of materials with suitable properties for these
applications, primarily because materials having the required durability in vivo
                                                                         -------
either lack the requisite biocompatibility or the ability to be easily injected.

         The Company has developed protein polymers that demonstrate excellent
biocompatibility, are soluble in water at room temperature, and are easily
injected into body tissues, irreversibly forming soft, durable gels at body
temperature. Previously, PPTI has shown gels of similar composition to persist
at least 18 months in an animal model.

         PPTI's bulking agents are unique in that they are applied as an aqueous
solution, easily injected through a 30-gauge needle, rapidly spreading
throughout the native tissue architecture. With the increase from room to body
temperature, the polymer solution irreversibly transforms within minutes to a
soft, pliable hydrogel. Importantly, the volume of material remains constant in
the liquid to gel transition, such that the tissue expansion observed by the
physician upon administration will be subsequently maintained.

         This is in direct contrast to the majority of competing technologies,
which are suspensions or slurries of solid particles in an aqueous carrier such
as saline. When injected through a fine gauge needle, with some difficulty due
to their thick constitution, the carrier liquid dissipates through the tissues
with time, usually within 24 hours, such that roughly half of the effective
bulking volume is lost. This requires the physician to either overcompensate for
the expected volume reduction upon initial administration, with increased risks
to the patient, or to

                                       7
<PAGE>

"top off" the bulking effect with repeated administrations of the product over
time, with substantially increased costs.

         Other hydrogel technologies of which the Company is aware are either
preformed gels, difficult to administer by injection, or polymer solutions mixed
with a chemical cross-linking agent prior to injection. PPTI believes that such
technologies are limited in their overall performance including durability,
biocompatibility and ease of administration.

         In August 1999, the Company obtained the FDA's approval of its
Investigational Device Exemption (IDE) to begin human clinical testing of its
urethral bulking agent for the treatment of female stress urinary incontinence.
The Company began pilot clinical testing of the product's safety and efficacy in
December 1999. The Company projects expanding into a multi-site pivotal clinical
study in the fourth quarter of 2000. To the extent funds are available, the
Company intends to submit an additional IDE to the FDA in 2000 to obtain
approval to begin human clinical testing of its dermal bulking agent for use in
cosmetic and reconstructive surgery applications.

         Surgical Adhesives and Sealants

         Surgeons are master craftsmen. However, instead of working with metal,
wood or plastic, they work with living tissues. Like carpenters, they use saws,
chisels (knives) and drills to take things apart and fit pieces together. But
they only have access to string (sutures) and nails (staples, pins, screws) to
hold things in place. Furthermore, a surgeon's work is complicated by the
biological healing response occurring when tissues are injured.

         As in everyday life, there are many surgical uses for glue where string
and nails just don't work well. They may not be quick or easy enough to use;
they may not be capable of staying in place; they may do more damage than
desired; they and/or the tools to use them may not fit within the available work
space; they may result in fluid or air leaks; or the "fit and finish" or healing
response is just not satisfactory.

         Certain surgical adhesives and sealants that seek to avoid these
limitations have been developed and marketed outside the United States by other
parties. In 1998, the FDA approved two such products for certain uses in the
U.S. DermaBond(TM), a cyanoacrylate adhesive, was approved for topical
application to close skin incisions and lacerations. Cyanoacrylate adhesives set
fast and have high strength, but are toxic to certain tissues and form brittle
plastics that do not resorb. These limitations restrict their use to bonding the
outer surfaces of skin together. Tisseel(TM), a fibrin sealant, was approved for
use as an adjunct to hemostasis in surgery. Fibrin sealants have excellent
hemostatic properties, but are derived from human and/or animal blood products,
set slowly, have low strength, and lose their strength rapidly.

         A third category of tissue adhesives combines natural proteins such as
collagen or albumin with aldehyde cross-linking agents. Such products are
marketed in Europe for limited life-threatening indications. The aldehyde
cross-linking agents employed (i.e. glutaraldehyde, formaldehyde) in such
products are known to cause adverse tissue reactions. Additional adhesive

                                       8
<PAGE>

and/or sealant products employing other polymer systems and cross-linking agents
are also under development.

         PPTI is seeking to develop surgical adhesives and sealants that combine
the biocompatibility of fibrin glues (without the risks associated with use of
blood-derived products) with the high strength and fast setting times of
cyanoacrylates. Unique features include significant elasticity within the
adhesive matrix (to move as tissues move) and the capability of tailoring the
resorption rate of the adhesive matrix with the rate at which the wound heals. A
non-resorbable adhesive or sealant can only be used where the damaged tissues
will not heal. Otherwise, a barrier to wound healing is unavoidably created.

         In September 1995, the Company entered into a series of agreements with
Ethicon regarding this program. Ethicon elected to terminate these agreements in
December 1997. However, the Company has demonstrated both the adhesive
performance and the biocompatibility of its product formulations in animal
models, including the resorption of the adhesive matrix in conjunction with the
progression of wound healing. Subsequently, the Company has worked to determine
the specific markets and products providing the most significant opportunities
for the use of its adhesive and sealant technology.

         As a result of its evaluations of the medical market needs, the
properties achievable with its technology, and the capabilities of competitive
technologies, PPTI has focused its product development interests on certain
orthopedic applications, particularly those related to the repair of the spinal
disc for the treatment of chronic low back pain. Low back pain is the most
common musculoskeletal disorder in industrialized societies. PPTI is committed
to the commercial development of its adhesive and sealant technology and is
seeking to establish new strategic alliances with market leaders. However, there
can be no assurance that such alliances can be entered into.

         Wound Healing/Tissue Engineering Matrices

         The current market for wound care products is highly segmented,
involving a variety of different approaches to wound care. Products currently
marketed and being developed by other parties include fabric dressings (such as
gauze), synthetic materials (such as polyurethane films) and biological
materials (such as growth factors and living tissue skin graft substitutes).
While the type of product used varies depending on the type of wound and extent
of tissue damage, the Company believes that a principal treatment goal in all
instances is to stimulate wound healing while regenerating functional (as
opposed to scar) tissue.

         The Company has developed protein polymers which it believes may be
useful in the treatment of dermal wounds, particularly chronic wounds such as
decubitous ulcers, where both reconstruction of the ECM and re-establishment of
its function are desired. These polymers, based on key ECM protein sequence
blocks, are biocompatible, fully resorbable and have been processed into gels,
sponges, films and fibrous sheets. The Company believes that such materials, if
successfully developed, could improve the wound-healing process by providing
physical support in situ for cell migration and tissue regeneration and as
                 -------
delivery systems for

                                       9
<PAGE>

growth factors. Additionally, such materials may serve as scaffolds for the
ex vivo production of living tissue substitutes.
- -------

         This program is in the early stages of research, which the Company has
principally conducted in collaboration with third parties. Such collaborations
have primarily focused on the treatment of dermal wounds.

         Controlled Release Drug Delivery

         Oral delivery of drugs is the most preferred route of administration.
However, for many drugs this is not possible and alternative drug delivery
routes are required. Alternative routes include transdermal, mucosal, and by
implantation or injection. For implantation or injection, it is often desirable
to extend the availability of the drug in order to minimize the frequency of
these invasive procedures. A few materials have been commercialized which act as
depots for a drug when implanted or injected, releasing the drug over periods
ranging from one month to several years. Other material and drug combinations
are being developed by third parties. PPTI believes that the properties of these
materials for such applications can be substantially improved upon, making
available the use of depot systems for a wider range of drugs and applications.

         PPTI's soft tissue augmentation products, its wound healing matrices,
and its medical device coating technology all provide platforms for drug
delivery applications, serving as controlled release drug depots. The protein
polymer materials the Company has developed exhibit exceptional
biocompatibility, provide for control over rates of resorption, and are
fabricated using aqueous solvent systems at ambient temperatures -- attributes
which can be critical in maintaining the activity of the drug, particularly
protein-based drugs emerging from the biotechnology industry. This program is in
the early stages of research.


MANUFACTURING, MARKETING AND DISTRIBUTION

         Preclinical and clinical testing of potential medical device products,
where the results will be submitted to the FDA, requires compliance with the
FDA's Good Laboratory Practices ("GLP") and other Quality System Regulations
("QSR"). The Company has implemented, and continues to implement, polymer
production and quality control procedures, and has made certain facilities
renovations to operate in conformance with FDA requirements. The Company
believes its current polymer production capacity is sufficient for supplying its
development programs with the required quality and quantity of materials needed
for feasibility and preclinical testing and initial ("pilot") clinical testing.
To expand beyond initial clinical trials, the Company will require additional
manufacturing capacity.

         The Company is considering several methods for increasing production of
its biomedical and other product candidates to meet clinical and commercial
requirements. For example, the Company may expand its existing facility to
produce needed quantities of materials under FDA's GLP and QSR regulations for
clinical and commercial use. Alternatively, the Company may establish external
contract manufacturing arrangements for needed quantities of materials.

                                       10
<PAGE>

However, there can be no assurance that such arrangements, if desired, could be
entered into or maintained on acceptable terms, if at all, or that the existence
or maintenance of such arrangements would not adversely affect the Company's
margins or its ability to comply with applicable governmental regulations. The
actual method, or combination of methods, that the Company may ultimately pursue
will depend on a number of factors, including availability, cost and the
Company's assessment of the ability of such production methods to meet its
commercial objectives.

         PPTI has entered into an agreement with Femcare for marketing and
distribution of its urethral bulking agent for stress urinary incontinence in
certain countries, if the required regulatory approvals are obtained (see
"Collaborative Agreements). The Company currently expects that its other
biomedical products, if any were commercialized, would be marketed and
distributed by corporate partners. While this arrangement could minimize the
Company's marketing costs and facilitate wider distribution of any biomedical
products it may develop, these arrangements could possibly reduce the Company's
revenues and profits as compared to what would be possible if the Company
directly sold such products.

RESEARCH AND DEVELOPMENT

         Information regarding Company-sponsored research and development
activities and contract research and development revenue is set forth below
under the heading "Management's Discussion and Analysis of Financial Condition
and Results of Operations".

COLLABORATIVE AGREEMENTS

         Because of the highly technical focus of its business, the Company must
conduct extensive research and development prior to any commercial production of
its biomedical products or the biomaterials from which they are created. During
this development stage, PPTI's ability to generate revenues is limited. Because
of this limitation, the Company does not have sufficient resources to devote to
extensive testing or marketing of its products. The Company's primary method of
expanding its product development, testing and marketing capabilities is to seek
to form collaborative arrangements with selected corporate partners with
specific resources that the Company believes complement its business strategies
and goals.

         The medical device industry has traditionally licensed from development
stage companies product candidates whose safety and efficacy has been
demonstrated at least in pilot human clinical trials. In December 1999, the
Company began human clinical testing of its urethral bulking agent for the
treatment of female stress urinary incontinence. The Company also intends to
submit an additional IDE to the FDA in 2000 to obtain approval to begin human
clinical testing of its dermal bulking agent for use in cosmetic and
reconstructive surgery applications.

                                       11
<PAGE>

         Femcare, Ltd.

         In January 2000, PPTI announced the formation of a strategic alliance
with Femcare, Ltd. for the commercialization in Europe and Australia of its
urethral bulking agent for treatment of stress urinary incontinence. Femcare is
a British-based developer and international marketer of surgical products for
gynecological and urological applications.

         In the alliance, PPTI will provide Femcare with technical assistance,
and the incontinence product for Femcare's clinical testing and regulatory
approvals in the Femcare territories. Femcare will utilize its existing customer
base and its extensive distribution network as the basis for introducing the
product into Europe and Australia. Currently, Femcare markets its products in 40
countries worldwide. A new Urology division has been created to extend the
company's success in gynecology to urological applications, in particular female
stress urinary incontinence. PPTI receives a $1 million license fee and a
royalty on the revenues generated by Femcare from the sale of the product. PPTI
will be responsible for providing the product to Femcare for commercial sale.

         Other Agreements

         PPTI is discussing other potential collaboration agreements with
prospective marketing partners for both its soft tissue augmentation products
and its tissue adhesive and sealant products. There can be no assurance that the
Company will continue such discussions or be able to establish such agreements
at all, or do so in a timely manner and on reasonable terms, or that such
agreements will lead to successful product development and commercialization.
From time to time, the Company is a party to certain materials evaluation
agreements regarding biomedical and specialty use applications of its products,
polymers and technology, including applications in areas other than those
identified as product candidates above. These agreements provide, or are
intended to provide, for the evaluation of product feasibility. There can be no
assurance that the Company will continue to be able to establish such agreements
at all, or do so in a timely manner and on reasonable terms, or that such
agreements will lead to joint product development and commercialization
agreements.

INTENSE COMPETITION

         The principal anticipated commercial uses of PPTI's biomaterials are as
components of end-use products for biomedical and other specialty applications.
End-use products using or incorporating the Company's biomaterials would compete
with other products that rely on the use of alternative materials. For example,
bulking agents for soft tissue augmentation are currently marketed based on
bovine collagen and, outside the U.S., silicone particles. Similarly, all
targeted applications of the Company's potential products will compete with
other products having the same or similar applications.

         The areas of business in which the Company engages and proposes to
engage are characterized by intense competition and rapidly evolving technology.
Competition in the biomedical and surgical repair markets is particularly
significant. The Company's competitors in

                                       12
<PAGE>

the biomedical and surgical repair markets include major pharmaceutical,
surgical product, chemical and specialized biopolymer companies, many of which
have financial, technical, research and development and marketing resources
significantly greater than those of the Company. Academic institutions and other
public and private research organizations are also conducting research and
seeking patent protection, and may commercialize products on their own or
through joint ventures. Most of the Company's competitors depend on synthetic
polymer technology rather than protein engineering for developing products.
However, the Company believes that DuPont and several university laboratories
are currently conducting research into similar protein engineering technology.

         The primary elements of competition in the biomedical and surgical
repair products market are performance, cost, safety, reliability, convenience
and commercial production capabilities. The Company believes that its ability to
compete in this market will be enhanced by its issued patent claims, the breadth
of its other pending patent applications, its early entry into its field and its
experience in protein engineering.

PATENTS AND TRADE SECRETS

         PPTI is aggressively pursuing domestic and international patent
protection for its technology, making claim to an extensive range of
recombinantly prepared structural and functional proteins, methods for preparing
synthetic repetitive DNA, methods for the production and purification of protein
polymers, end-use products incorporating such materials and methods for their
use.

         The United States Patent and Trademark Office ("USPTO") has issued
fifteen patents to the Company. U.S. Patent 5,235,041 (1993) relates to the
Company's method for purifying structurally ordered recombinant protein
polymers. U.S. Patent 5,243,038 (1993) covers the Company's synthetic DNA
compositions that encode polymers and copolymers comprising the amino acid
"building blocks" of silk and elastin. U.S. Patent 5,496,712 (1996) covers the
Company's family of high molecular weight collagen like polymers and the DNA
sequences encoding them. U.S. Patent 5,514,581 (1996) covers DNA sequences
encoding silk-like structural building blocks with an intervening sequence
coding for the key cell attachment ligand from human fibronectin. One of the
claimed sequences encodes ProNectin F.

         U.S. Patent 5,606,019 (1997) covers the protein compositions comprising
copolymers of the amino acid "building blocks" of silk and elastin. These are
the primary materials used in the Company's current product development efforts.
U.S. Patent 5,641,648 (1997) covers methods by which synthetic genes encoding
protein polymers are created.

         U.S. Patent 5,723,588 (1998) covers molded articles incorporating
biologically active proteins. U.S. Patent 5,760,004 (1998) covers chemical
modification of protein polymers to enhance their water solubility. U.S. Patent
5,770,697 (1998) broadly covers protein polymers incorporating repetitive amino
acid sequences found in naturally occurring proteins. U.S. Patent 5,773,249
(1998) expands the coverage of high molecular weight collagen like polymers.
U.S. Patent 5,773,577 (1998) covers protein polymers that can be cross-linked by
certain enzymes

                                       13
<PAGE>

that naturally occur in the body. U.S. Patent 5,808,012 (1998) expands the
coverage of molded articles to those incorporating chemically active proteins.
U.S. Patent 5,817,303 (1998) covers the use of protein polymers with chemical
cross-linking agents as adhesives and sealants. U.S. Patent 5,830,713 (1998)
expands the coverage of methods by which synthetic genes encoding protein
polymers are created. U.S. Patent 6,018,030 (2000) broadly covers DNA sequences
encoding protein polymers incorporating repetitive amino acid sequences found in
naturally occurring proteins. Additionally, PPTI has nine U.S. patent
applications pending, two of which have been allowed, covering related aspects
of its core technology.

         Although the Company believes its existing issued patent claims may
provide a competitive advantage, there can be no assurance that the scope of the
Company's patent protection is or will be adequate to protect its technology or
that the validity of any patent issued will be upheld in the future.
Additionally, with respect to the Company's allowed and pending applications,
there can be no assurance that any patents will be issued, or that, if issued,
they will provide substantial protection or be of commercial benefit to the
Company. The two patents issued to PPTI in 1993 will expire in 2010, as will one
of the patents issued in 1996. The other patent issued in 1996 will expire in
2013, and the patents issued in 1997 will expire in 2014. The three patents
issued in 1998, which expand the coverage of previously issued patents, will
expire in concert with the original patents. The other five patents issued in
1998 will expire in 2015. The patent issued in 2000 will expire in 2017.

         Generally, for patent applications filed in the U.S. prior to June 8,
1995, the term of the patent will be 17 years from the issue date. Subsequently
filed U.S. patent applications will have a term of 20 years from the date of
filing, consistent with the patent laws in international jurisdictions.

         Although the Company does not currently have any operations outside the
U.S., it anticipates that its potential products will be marketed on a worldwide
basis, with possible manufacturing operations outside the U.S. For example, the
Company has recently established a licensing and distribution agreement with
Femcare Ltd. for the sale of its urethral bulking agents in Europe and
Australia. Accordingly, international patent applications corresponding to the
major U.S. patents and patent applications described above have been filed in
these and other important market jurisdictions. Due to translation costs and
patent office fees, international patents are significantly more expensive to
obtain than U.S. patents. Additionally, there are differences in the
requirements concerning novelty and the types of claims that can be obtained
compared to U.S. patent laws, as well as the nature of the rights conferred by a
patent grant. PPTI carefully considers these factors in consultation with its
patent counsel, as well as the size of the potential markets represented, in
determining the foreign countries in which to file patents.

         In almost all cases, the Company files for patents in Australia,
Canada, Europe and Japan. Currently, PPTI has fourteen issued foreign patents,
and thirty-one pending foreign applications. One of the issued foreign patents
is in Europe and the scope of its claims broadly covers protein polymers having
biological or chemical activity.

                                       14
<PAGE>

         Because of the uncertainty concerning patent protection and the
unavailability of patent protection for certain processes and techniques, PPTI
also relies upon trade secret protection and continuing technological innovation
to maintain its competitive position. Although all of the Company's employees
have signed confidentiality agreements, there can be no assurance that the
Company's proprietary technology will not be independently developed by other
parties, or that secrecy will not be breached. Additionally, the Company is
aware that substantial research efforts in protein engineering technology are
taking place at universities, government laboratories and other corporations and
that numerous patent applications have been filed. The Company cannot predict
whether it may have to obtain licenses to use any technology developed by third
parties or whether such licenses can be obtained on commercially reasonable
terms, if at all.

         In the course of its business, PPTI employs various trademarks and
trade names in packaging and advertising its products. The Company has assigned
the federal registration of its ProNectin(R) trademark and its SmartPlastic(R)
trademark for ProNectin F Activated Cultureware to Sanyo Chemical Industries,
Ltd. in connection with the sale to Sanyo of its cell culture business. The
Company intends to protect and promote all of its trademarks and, where
appropriate, will seek federal registration of its trademarks.

REGULATORY MATTERS

         Regulation by governmental authorities in the United States and other
countries is a significant factor affecting the success of products resulting
from biotechnological research. The Company's current operations and products
are, and anticipated products and operations will be, subject to substantial
regulation by a variety of agencies, particularly those products and operations
related to biomedical applications. Currently, the Company's activities are
subject principally to regulation under the Occupational Safety and Health Act
and the Food, Drug and Cosmetic Act.

         Extensive preclinical and clinical testing and pre-market approval from
the FDA is required for new medical devices, drugs or vaccines, which is
generally a costly and time-consuming process. PPTI is required to be in
compliance with many of the FDA's regulations to conduct testing in support of
product approvals; in particular, compliance with the FDA's Good Laboratory
Practices ("GLP") regulations and portions of the FDA's Quality Systems
Regulations ("QSR"). Where PPTI has conducted such testing, the Company may
choose to file product approval submissions itself or maintain with the FDA a
"Master File" containing, among other items, such test results. A Master File
can then be accessed by the FDA in reviewing particular product approval
submissions from companies commercializing products based on PPTI's materials.

         There can be no assurance that the Company or its customers will be
able to obtain or maintain the necessary approvals from the FDA or corresponding
international regulatory authorities, or that the Company will be able to
maintain a Master File in accordance with FDA regulations. In either case, the
Company's anticipated business could be adversely affected. To the extent PPTI
manufactures medical devices, as opposed to a component material supplied to a
medical device manufacturer, it will be required to conform commercial
manufacturing operations

                                       15
<PAGE>

to the FDA's QSR requirements. The Company would also be required to register
its facility with the FDA as an establishment involved in the manufacture of
medical devices. QSR requirements are rigorous, and there can be no assurance
that compliance could be obtained in a timely manner and without the expenditure
of substantial resources, if at all. International quality system requirements,
i.e., ISO 9001 issued by the International Organization for Standardization is
the quality model used by medical product manufacturers, and is required for the
sale of medical devices in Europe. ISO 9001 standards are similar to the FDA's
QSR.

         In August 1999, the Company obtained the FDA's approval of its IDE to
begin human clinical testing of its urethral bulking agent for the treatment of
female stress urinary incontinence. The Company initiated clinical testing in
December 1999. The Company intends to submit an additional IDE to the FDA in
2000 to obtain approval to begin human clinical testing of its dermal bulking
agent for use in cosmetic and reconstructive surgery applications. The Company
has implemented, and continues to implement, polymer production and quality
control procedures, and has made certain facilities renovations, to operate in
conformance with FDA requirements.

         The Company's research, development and production activities are, or
may be, subject to various federal and state laws and regulations relating to
environmental quality and the use, discharge, storage, transportation and
disposal of toxic and hazardous substances. The Company's future activities may
be subject to regulation under the Toxic Substances Control Act, which requires
the Company to obtain pre-manufacturing approval for any new "chemical material"
the Company produces for commercial use that does not fall within the FDA's
regulatory jurisdiction. The Company believes it is currently in substantial
compliance with all such laws and regulations. Although the Company intends to
use its best efforts to comply with all environmental laws and regulations in
the future, there can be no assurance that the Company will be able to fully
comply with such laws, or that full compliance will not require substantial
capital expenditures.

PRODUCT LIABILITY AND ABSENCE OF INSURANCE

         PPTI's business may expose it to potential product liability risks
whenever human clinical testing is performed or upon the use of any commercially
marketed medical product. Prior to initiating human clinical testing of its
urethral bulking agent, the Company procured product liability insurance. There
can be no assurance, however, that PPTI will be able to continue to obtain such
insurance on acceptable terms or that such insurance will provide adequate
coverage against potential liabilities. A successful product liability claim or
series of claims could result in a material adverse effect on the Company.

</TABLE>


         Mr. Parmeter has been the Company's President, Chief Executive Officer
and Chairman of the Board of Directors since its inception in July 1988 (and,
from July 1988 to July 1992, its Chief Financial Officer). From 1982 to November
1987, Mr. Parmeter was President, Chief Executive Officer and, from June 1987 to
June 1988, Chairman of the Board of Syntro Corporation.

         Dr. Cappello has been the Company's Vice President, Research and
Development since February 1997 and Director, Polymer Research and Chief
Technical Officer since February 1993. From September 1988 to February 1993, he
was the Company's Senior Research Director, Protein Engineering.

         Mr. Davis has been the Company's Secretary since January 1989. Mr.
Davis has been a director of the Company since April 1995; he previously served
as a director of the Company from January 1989 until October 1991. Mr. Davis has
been employed by Donaldson, Lufkin & Jenrette since June 1994 and currently is a
Managing Director of Investment Banking. He was Director, Institutional Sales at
Merrill Lynch, Inc. (formerly Merrill Lynch Capital Markets) from February 1991
to June 1994, and was a Vice President at Merrill Lynch, Inc. from 1986 to 1991.


         Mr. Flowers has been the Company's Vice President, Planning and

         Dr. Ferrari has been the Company's Vice President, Laboratory
Operations and Director, Molecular Genetics since February 1993. From September
1988 to February 1993, he was the Company's Senior Research Director, Genetic
Engineering.

         Ms. Neves has been the Company's Director of Finance since November
1998 and Controller and Assistant Secretary since January 1990. From July 1988
until January 1990, Ms. Neves was the Company's Business Office Manager.

         All executive officers of the Company were elected by the Board of
Directors and serve at its discretion. No family relationships exist between any
of the officers or directors of the Company.

EMPLOYEES

         On June 30, 1999, the Company laid off eighteen employees,
approximately 60% of its work force, as part of a broad cost cutting measure to
preserve cash. In late July, several employees were brought back on the payroll
in order to prevent delays in beginning the clinical testing of the Company's
lead product, scheduled to begin in December, 1999. With the closing of the
Series G Preferred stock offering, several more of the laid off employees were
rehired.

         As of February 29, 2000, PPTI had 19 full-time and one part-time
employee, of whom four hold employment contracts with the Company and three hold
Ph.D. degrees in the chemical or biological sciences. The Company is highly
dependent on the services of its executive officers and scientists. The loss of
the services of any one of these individuals would have a material adverse
effect on the achievement of the Company's development objectives, its business
opportunities and prospects. The recruitment and retention of additional
qualified management and scientific personnel is also critical to the Company's
success. There can be no assurance that the Company will be able to attract and
retain required personnel on acceptable terms, due to the competition for such
experienced personnel from other biotechnology, pharmaceutical, medical device
and chemical companies, universities and non-profit research institutions.


ITEM 2.  PROPERTIES

         PPTI does not own any real property. The Company leases approximately
21,000 square feet in San Diego, California from Sycamore/San Diego Investors.
The leased property includes the Company's administrative offices, which
encompass approximately 4,000 square feet, and its laboratory facilities, which
encompass approximately 17,000 square feet. The current annual rent is
approximately $417,000. The lease expires in May 2005.

         The Company believes that its current facilities are adequate to meet
its needs until the end of 2000. The Company retains an option to lease an
additional 7,000 square feet of office and laboratory space in its present
facility and to extend its lease for an additional five years.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

NASDAQ Delisting

         Prior to September 1999, the Company's Common Stock traded on The
Nasdaq Stock Market under the symbol "PPTI". The Company's Common Stock was
delisted from the NASDAQ Small Cap Quotation System, effective September 20,
1999. The reasons for the delisting were failure to maintain the minimum bid
requirement of $1.00 per share for PPTI common stock, and failure to meet the

         As of March 22, 2000, the Company had approximately 163 shareholders
of record; it estimates it has approximately 1,500 beneficial holders. The
Company has never paid cash dividends on its Common Stock. The Company currently
intends to retain earnings, if any, for use in the operation and expansion of
its business and therefore does not anticipate paying any cash dividends on the
Common Stock in the foreseeable future.

Unregistered Offerings

         On August 16, 1999, the Company received $1,775,000 for 17,750 shares
of Series G Convertible Preferred Stock ("Series G Stock") from several
institutional and accredited individual investors following the 10 day
stockholder notification period required by the NASD prior to the sale. On
September 15, 1999, the Company received an additional $325,000 for 3,250 shares
of Series G Stock, for a total of $2,100,000. Each share of Series G Stock was
priced

                                       20
<PAGE>

at $100 per share. Each share can be converted at any time by the holder into
common stock at a price of $0.50 per share, subject to certain antidilution
adjustments. Each share of Series G Preferred Stock also received a common stock
warrant, exercisable for 12 months, that allows the holder to acquire 200 shares
of PPTI common stock at a price of $0.50 per share. The Series G Stock, warrants
and underlying common stock have not been registered under the Securities Act of
1933, as amended (the "Securities Act"), and may not be offered or sold in the
United States absent registration or an applicable exemption from registration
requirements.

         Between April 1 and April 15, 1999, the Company received approximately
$508,000 from the exercise of redeemable, publicly traded, warrants originally
issued as part of PPTI's Initial Public Offering. Following the close of
business on April 15, the remaining unexercised redeemable, publicly traded,
warrants expired. On May 12, 1999, the Company received approximately $416,000
from the exercise of warrants issued in conjunction with the private placement
of the Company's Series E Convertible Preferred Stock ("Series E Stock").

         In April and May of 1998, the Company raised approximately $5.4 million
from the sale of 54,437 shares of the Company's Series E Stock priced at $100
per share, with warrants to purchase an aggregate of 3,266,250 shares of common
stock to a small group of institutional and accredited investors.

         Each share of Series E Stock is convertible at any time at the election
of the holder into 80 shares of common stock at a conversion price of $1.25 per
share, subject to certain antidilution adjustments. No underwriters were engaged
by the Company in connection with such issuance and, accordingly, no
underwriting discounts were paid. The offering is exempt from registration under
Section 4(2) of the Securities Act, and met the requirements of Rule 506 of
Regulation D promulgated under the Securities Act. The Company has registered
the shares of common stock underlying the Series E Stock and the warrants with
the Securities and Exchange Commission.

         Each share of Series E Stock received two common stock warrants. One
warrant (first warrant) is exercisable at any time for 40 shares of common stock
at an exercise price of $2.50 per share, and expires approximately 18 months
after the close of the offering; the other warrant (second warrant) is
exercisable at any time for 20 shares of common stock at an exercise price of
$5.00 per share, and expires approximately 36 months after the close of the
offering. In addition, an 18 month warrant to acquire 200,000 common shares
exercisable at $2.50 per share and a 36 month warrant to acquire 100,000 common
shares exercisable at $5.00 per share were issued as a finder and document
review fee paid to a lead investor. An 18 month warrant to acquire 32,000 common
shares exercisable at $2.50 per share, a 24 month warrant to acquire 16,000
common shares exercisable at $5.00 per share, and 5 year warrants to acquire an
aggregate of 25,200 common shares exercisable at $2.50 per share were issued to
certain persons for service as finders in relation to the private placement.

         In connection with the above private placement, the Company issued
26,420 shares of its Series F Convertible Preferred Stock in exchange for the
same number of shares of outstanding Series D Convertible Preferred Stock. The
Company's Series F Convertible Preferred Stock is equivalent to the Company's
Series E Stock with regard to liquidation preferences. All other

                                       21
<PAGE>

terms of the Company's Series F Convertible Preferred Stock remained the same as
the Company's Series D Convertible Preferred Stock.

         On January 7, 1997, the Company received $4,760,000, less expenses of
approximately $140,000, from a private placement of 1,904,000 shares of the
Company's common stock, at $2.50 per share, with a number of accredited
investors. No underwriters were engaged by the Company in connection with such
issuance and, accordingly, no underwriting discounts or commissions were paid.
The issuance was exempt from registration under Section 4(2) of the Securities
Act, and met the requirements of Rule 506 of Regulation D promulgated under the
Securities Act. The Company agreed to register the shares with the Securities
and Exchange Commission promptly after the closing. The registration was
declared effective on January 24, 1997.

         On September 14, 1995, the Company issued 49,187 shares of its Series D
Convertible Preferred Stock and warrants to purchase 500,960 shares of common
stock at $1.25 per share in a private placement to certain accredited investors.
Of this amount, 20,000 shares of Series D Convertible Preferred Stock and
warrants to purchase 400,000 shares of common stock were issued for cash at
$100.00 per share; 21,600 shares of Series D Convertible Preferred Stock were
issued in exchange for all outstanding shares of the Company's Series C
Convertible Preferred Stock and 2,539 shares for accrued and unpaid dividends
thereon; and an additional 5,048 shares of Series D Convertible Preferred Stock
and warrants to purchase 100,960 shares of common stock were issued in exchange
for cancellation of a $500,000 bridge loan and accrued interest thereon. No
underwriters were engaged by the Company in connection with such issuance and,
accordingly, no underwriting discounts or commissions were paid. The issuance
was exempt from registration under Section 4(2) of the Securities Act and met
the requirements of Rule 506 of Regulation D promulgated under the Securities
Act.

         Each share of Series D and Series F Convertible Preferred Stock earns a
cumulative dividend at the annual rate of $10 per share, payable as and when
declared by the Company's Board of Directors in the form of cash, common stock
or any combination thereof. The Series D and F Convertible Preferred Stock is
convertible into common stock after two years from the date of issuance at the
holder's option. The conversion price at the time of conversion is the lesser of
$3.75 or the market price. The Series D and F Convertible Preferred Stock is
redeemable at the Company's option after four years from the date of issuance.
Automatic conversion of all of the Series D and F Convertible Preferred Stock
will occur if: (a) the Company completes a public offering of common stock at a
price of $2.50 or higher; or (b) the holders of a majority thereof elect to
convert. The Company has the option to demand conversion of the Series D and F
Convertible Preferred Stock if the average market price of its common stock
equals or exceeds $5.00 per share over a period of twenty business days. The
Series D Convertible Preferred Stock has a liquidation preference of $100 per
share plus accumulated dividends.

         At the time of purchase, the Series D Convertible Preferred
stockholders received warrants to purchase, at an exercise price of $1.25 per
share, twenty shares of the Company's common stock for each share of Series D
Convertible Preferred Stock acquired for cash, or upon conversion of the
outstanding bridge loan and accrued interest thereon, described above. Warrants

                                       22
<PAGE>

to acquire a total of 500,960 shares of common stock were issued. All of these
warrants were exercised during 1996, from which the Company received aggregate
gross proceeds of $626,200. The Series D Convertible Preferred stockholders were
granted certain registration rights relating to their shares of common stock
issuable upon conversion of the Series D Convertible Preferred Stock and upon
the exercise of their warrants.

         In July 1994, the Company received $2,160,000 from a private placement
of the Company's Series C Convertible Preferred Stock with certain accredited
investors, consisting of 21,600 shares at $100.00 per share. No underwriters
were engaged by the Company in connection with such issuance and, accordingly,
no underwriter discounts or commissions were paid. The issuance was exempt from
registration under Section 4(2) of the Securities Act and met the requirements
under Rule 506 of Regulation D promulgated under the Securities Act. As
described above, the investors exchanged 21,600 shares of Series C Convertible
Preferred Stock, plus accrued and unpaid dividends thereon, for 24,139 shares of
Series D Convertible Preferred Stock. There are currently no shares of Series C
Convertible Preferred Stock outstanding.

         In connection with the issuance of the Series C Convertible Preferred
Stock, warrants were also issued to acquire a total of 432,000 shares of the
Company's common stock at a price of $1.25 per share. All of these warrants were
exercised during 1996, from which the Company received aggregate gross proceeds
of $540,000.

         In July 1996, holders of warrants to acquire 322,663 shares of common
stock (all of whom were accredited investors) exercised such warrants at $2.50
per share, resulting in approximately $807,000 in gross proceeds to the Company.
These warrants were originally issued in 1991 in connection with the issuance of
the Company's Series B Convertible Preferred Stock. The issuance upon exercise
of these warrants was exempt from registration under Section 4(2) of the
Securities Act and met the requirements under Rule 506 of Regulation D
promulgated under the Securities Act. The Company agreed to register the resale
of the common stock received upon exercise of these warrants, and the applicable
registration was declared effective on July 19, 1996.

GENERAL OVERVIEW

         Incorporated in 1988, Protein Polymer Technologies, Inc. has
concentrated its research and development efforts on establishing a scientific
and technical leadership position in the production and development of unique
protein-based materials. The Company has identified biomedical market and
product opportunities for further research and development that management
believes will exploit the unique properties of the Company's technology to
competitive advantage. The Company has been unprofitable to date, and as of
December 31, 1999 has an accumulated deficit of $37,245,495.

         The Company's product candidates for surgical repair, augmentation and
regeneration of human tissues are in various stages of research and development.
Its more advanced programs are in the areas of bulking agents for soft tissue
augmentation, particularly for use in urethral tissue for the treatment of
female stress incontinence and in dermal tissue for cosmetic and reconstructive
procedures. The Company currently is devoting the majority of its resources to
the development and registration of these products, with the greatest emphasis
on the incontinence product which began human clinical trials in December 1999.
The Company's other advanced product technology is in the area of tissue
adhesives and sealants. Currently the Company's research and development in this
area is focused on the repair of spinal discs for the treatment of lower back
pain. The Company's first commercial products, ProNectin F and SmartPlastic, are
used by biologists and cell culture laboratories, principally to grow mammalian
cells for biomedical research purposes. In February 2000, the Company licensed
the rights for the

                                       24
<PAGE>

manufacture and sale of these products for use in in vitro cell culture,
                                                   -------
including the transfer of all existing inventory, to a third party.

         In 1995, the Company entered into a collaborative relationship with
Ethicon regarding its surgical adhesives and sealants program. Ethicon
terminated the relationship in December 1997 which materially adversely affected
the Company. The Company's strategy with most of its programs is to enter into
collaborative development agreements with major medical product marketing and
distribution companies. Although these relationships, to the extent any are
consummated, may provide significant near-term revenues through up-front
licensing fees, research and development reimbursements and milestone payments,
the Company expects to continue incurring operating losses for the next several
years.

         The Company's cash balance as of December 31, 1999 was $156,000. The
Company believes this amount, in combination with funds received from licensing
and R&D agreements in January and February 2000, and the exercise of the common
stock warrants issued in connection with the Series G Stock in February 2000,
which in total will generate approximately $3.4 million (net of costs) during
the calendar year 2000, is sufficient to fund its operations through January
2001. The Company will continue to attempt to raise additional funds for
continuing operations through private or public offerings and collaborative
agreements (see "Liquidity and Capital Resources" below, and Note 1 of the
Audited Financial Statements for additional information and a description of the
associated risks).

RESULTS OF OPERATIONS

         Interest income was $39,000 for the year ended December 31, 1999, as
compared to $135,000 for 1998 and $187,000 for 1997. The year-to-year
variability resulted from the amount and timing of the receipt of equity capital
and the amounts of excess cash available for investment.

         Product sales for the years ended December 31, 1999 were $54,000,
compared to $71,000 and $77,000 in 1998 and 1997 respectively. Product sales
consist of ProNectin F related product revenues and licensing fees. Sales during
1996 reflected disappointing market interest in the line of ProNectin products;
as a result the Company discontinued related promotional expenditures to
conserve cash. Sales in 1998 and 1999 primarily reflect distributor stocking
orders. The manufacturing and marketing rights and the inventory for this
product line were sold to Sanyo Chemical Industries, Ltd. in February 2000.
Because of previously booked inventory reserves, their was no cost of sales
booked for any product sales in 1999.

         Research and development expenses for the year ended December 31, 1999
were $2,812,000, compared to $4,138,000 in 1998, a decrease of 32%. This
decrease is due primarily to a downsizing of the Company's staff and operational
expenses in June 1999, but also in part to the completion of preclinical testing
and regulatory consulting costs associated with the filing of the Company's
Investigational Device Exemption (IDE) with the U.S. Food and Drug
Administration to begin human trials for the treatment of female stress urinary
incontinence. These latter savings are temporary and will be replaced and
increased by the cost of conducting

                                       25
<PAGE>

human clinical testing which began in December 1999. Other related expenses
include expanded manufacturing capacity and manufacturing process validation,
quality assurance efforts, and outside testing services. The Company expects its
research and development expenses will increase in the future, to the extent
additional capital is obtained, due to the expansion of product-directed
development efforts including human clinical testing, increased manufacturing
requirements, and increased use of outside testing services.

         Selling, general and administrative expenses for the year ended
December 31, 1999 were $1,554,000, as compared to $1,727,000 for 1998, a
decrease of 10%. This decrease was due to the Corporate downsizing in June 1999,
and generally tighter cost management following that period. To the extent
possible, the Company continues to concentrate on controlling costs reflected in
reduced travel, office supplies, and non-regulatory consulting costs. The
Company expects its selling, general and administrative expenses will increase
in the future, to the extent additional capital is obtained, consistent with
supporting its research and development efforts and as business development,
patent, legal and investor relations activities require.

         For the year ended December 31, 1999, the Company recorded a net loss
applicable to common shareholders of $4,535,000, or $.36 per share, as compared
to $9,183,000, or $.88 per share for 1998, and $4,887,000, or $.52 per share for
1997. The difference between 1999 and previous year end results is due primarily
to a non-cash "imputed dividend" expense of $3,266,000 that resulted from the
sale and issuance of the Company's Series E Convertible Preferred Stock during
1998. The 1999, 1998 and 1997 losses and per share calculations also include
$278,000, $278,000, and $433,000, respectively, of undeclared and/or paid
dividends from the Company's Preferred Stock.

         The Company expects to incur increasing operating losses for the next
several years, to the extent additional capital is obtained, based upon the
successful continuation of the tissue augmentation program and product
registration, and the tissue adhesives program, as well as expected increases in
the Company's other research and development, manufacturing and business
development activities. The Company's results depend in part on its ability to
establish strategic alliances and generate contract revenues, increased
research, development and manufacturing efforts, preclinical and clinical
product testing and commercialization expenditures, expenses incurred for
regulatory compliance and patent prosecution, and other factors. The Company's
results will also fluctuate from period to period due to timing differences.

         To date, the Company believes that inflation and changing prices have
not had a material impact on its continuing operations. Based upon the Company's
earnings history, a valuation allowance of $12,867,000 is required to reduce the
Company's net deferred tax assets to the amount realizable.

                                       26

LIQUIDITY AND CAPITAL RESOURCES

         As of December 31, 1999, the Company had cash, cash equivalents and
short-term investments totaling $156,000, as compared to $1,383,000 at December
31, 1998. As of December 31, 1999, the Company had working capital of
$(458,000), compared to $600,000 at December 31, 1998. In April and May of 1999,
the Company realized approximately $924,000 from the exercise of common stock
warrants and in August and September 1999, approximately $2,075,000, net of
expenses, from the private placement of the Company's Series G Convertible
Preferred Stock and warrants. Subsequently, the Company received in January and
February 2000 approximately $1,350,000 (net of costs) in cash and receivables
from licensing and R&D agreements with Femcare, Ltd. for the European and
Australian marketing rights to the stress urinary incontinence bulking product,
with Perkin-Elmer for a research and development project and commercialization
option, and with Sanyo Chemical Industries, Ltd. for the rights to the in vitro
cell culture business. Also in February 2000, the Company received approximately
$2.1 million from the exercise of common stock warrants originally granted as
part of the sale of Series G Convertible Preferred Stock and warrants.

         The Company had long-term capital lease obligations of $25,000 as of
December 31, 1999, compared to an obligation of $106,000 as of December 31,
1998. For the year ended December 31, 1999, the Company's cash expenditures for
capital equipment and leasehold improvements totaled $26,000, compared with
$197,000 for the same period last year. The Company anticipates that these
expenditures will be increased in 2000 as laboratory renovations and additional
equipment required to meet GLP manufacturing regulations and production capacity
as the Company scales up its manufacturing operations to meet product
requirements for clinical testing. The Company anticipates a significant
increase in manufacturing-related equipment and leasehold improvement
expenditures in 2001 due to an increase in need for products for clinical
testing, and anticipated need for additional product manufacturing for European
product sales. The Company may enter into additional capital equipment lease
arrangements in the future if available at appropriate rates and terms.

         The Company believes its existing available cash, cash equivalents and
short-term investments as of February 29, 2000 would be sufficient to meet its
anticipated capital requirements through December 2000. Substantial additional
capital resources will be required to fund continuing expenditures related to
the Company's research, development, manufacturing and business development
activities. The Company believes there may be a number of alternatives available
to meet the continuing capital requirements of its operations, such as
collaborative agreements and public or private financings. During 2000, the
Company expects that the possible exercise of other existing warrants could
result in additional funds for continuing operations. Further, the Company is
currently in preliminary discussions with a number of potential collaborative
partners and, based on the results of various materials evaluations, revenues in
the form of license fees, milestone payments or research and development
reimbursements could be generated. There can be no assurance that any of these
fundings will be consummated in the necessary timeframes needed for continuing
operations or on terms favorable to the Company. If adequate funds are not
available, the Company will be required to significantly curtail its

                                       27
<PAGE>

operating plans and may have to sell or license out significant portions of the
Company's technology or potential products.

YEAR 2000 COMPLIANCE

         The Company's plan to modify its information technology in recognition
of the year 2000 issue has been successfully implemented. The "Year 2000" issue
concerned potential exposure related to the interruption of business practice
and financial misinformation resulting from the application of computer programs
which have been written using two digits, rather than four, to define the
applicable year of business transactions. Based on its assessments to date, the
Company does not expect to incur any further significant costs, or anticipate
any significant problems or uncertainties associated with remaining Year 2000
compliant.

                Report of Ernst & Young LLP, Independent Auditors


The Board of Directors and Stockholders
Protein Polymer Technologies, Inc.


         We have audited the accompanying balance sheets of Protein Polymer
Technologies, Inc. (a Development Stage Company) as of December 31, 1999 and
1998, and the related statements of operations, stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1999 and for
the period July 6, 1988 (inception) to December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

         We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Protein Polymer
Technologies, Inc. (a Development Stage Company) at December 31, 1999 and 1998,
and the results of its operations and its cash flows for each of the three years
in the period ended December 31, 1999 and for the period July 6, 1988
(inception) to December 31, 1999 in conformity with accounting principles
generally accepted in the United States.

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BUSINESS ACTIVITIES

Protein Polymer Technologies, Inc. (the "Company") was established to design,
produce and market genetically engineered protein polymers for a variety of
biomedical and specialty materials applications. The Company was incorporated in
Delaware on July 6, 1988. For the period from its inception to date, the Company
has been a development stage enterprise, and accordingly, the Company's
operations have been directed primarily toward developing business strategies,
raising capital, research and development activities, conducting clinical
testing of its product candidates, exploring marketing channels and recruiting
personnel. The Company operates in one segment.

LIQUIDITY

As of December 31, 1999, the Company had cash, cash equivalents and short-term
investments totaling $156,000. In January and February 2000 the Company received
approximately $1,350,000 in cash and receivables from licensing and R&D
agreements with Femcare, Ltd. for the European and Australian marketing rights
to the stress urinary incontinence bulking product, with Perkin-Elmer for a
research and development project and commercialization option, and with Sanyo
Chemical Industries, Ltd. for the marketing rights, manufacturing technology,
and inventory for the in vitro cell culture business. Also in February 2000, the
Company received approximately $2 million net of costs from the exercise of
common stock warrants originally granted as part of the sale of Series G
Convertible Preferred Stock.

The Company believes its available cash, cash equivalents and short-term
investments would be sufficient to meet its anticipated capital requirements
through January 2001. Prior to the commercialization of its products,
substantial additional capital resources will be required to fund continuing
operations related to the Company's research, development, manufacturing,
clinical testing, and business development activities. The Company believes
there may be a number of alternatives available to meet the continuing capital
requirements of its operations, such as collaborative agreements and public or
private financings. During 2000, the Company expects that the possible exercise
of existing warrants could result in additional funds for continuing operations.
Further, the Company is currently in discussions with a number of potential
collaborative partners and, based on the results of various materials
evaluations, revenues in the form of license fees, milestone payments or
research and development

reimbursements could be generated. There can be no assurance that any of these
fundings will be consummated in the necessary time frames needed for continuing
operations or on terms favorable to the Company. If adequate funds in the future
are not available, the Company will be required to significantly curtail its
operating plans and may have to sell or license out significant portions of the
Company's technology or potential products.


CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

Cash and cash equivalents consist of cash and highly liquid investments which
include debt securities with remaining maturities of three months or less when
acquired. Short-term investments consist primarily of commercial paper, notes
and short-term U.S. Government securities with original maturities beyond three
months and are stated at estimated fair value. Similar items with original
maturities of three months or less are considered cash equivalents. The Company
has established guidelines relative to diversification and maturities that
maintain safety and liquidity. The Company has not experienced any losses on its
short-term investments.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS

Equipment and leasehold improvements are stated at cost, less accumulated
depreciation and amortization. Equipment is depreciated over the estimated
useful life of the asset, typically one to seven years, using the straight-line
method. Leasehold improvements are amortized over the shorter of the lease term
or life of the asset. Equipment and leasehold improvements consist of the
following:

RESEARCH AND DEVELOPMENT REVENUES AND EXPENSES

License fees and research and development contract revenues are recorded as
earned based on the performance requirements of the contracts. If the research
and development activities are not successful, the Company is not obligated to
refund payments previously received. Milestone payments are recorded as revenue
when received as they have not been refundable and the Company has no future
performance obligations. Payments received in advance of amounts earned are
recorded as deferred revenue. Research and development costs are expensed as
incurred.

PRODUCT REVENUE RECOGNITION

Sales are recognized upon shipment of products to customers.

IMPAIRMENT OF LONG-LIVED ASSETS

In accordance with Statement of Financial Accounting Standards ("SFAS") No. 121,
Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed Of, if indicators of impairment exist, the Company assesses the
recoverability of the affected long-lived assets by determining whether the
carrying value of such assets can be recovered through undiscounted future
operating cash flows. If impairment is indicated, the Company will value the
asset at fair value. While the Company's current and historical operating and
cash flow losses are indicators of impairment, the Company believes the future
cash flows to be received from the long-lived assets will exceed the assets'
carrying value, and accordingly the Company has not recognized any impairment
losses through December 31, 1999.

STOCK OPTIONS

As permitted by SFAS No. 123, Accounting for Stock-Based Compensation, the
Company has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees, ("APB 25") and related Interpretations
in accounting for its employee stock options. Under APB 25, if the exercise
price of the Company's employee stock options equals or exceeds the fair value
of the underlying stock on the date of grant, no compensation expense is
recognized. Options issued to non-employees are recorded at their fair value and
recognized over the related service period. The effects of using the fair value
accounting method, as described in SFAS Statement No. 123 are described below in
Note 2.

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (continued)

NET LOSS PER COMMON SHARE

The Company reports its earnings per share in accordance with SFAS No. 128,
Earnings per Share, which requires the presentation of both basic and diluted
earnings per share on the statements of operations. Basic earnings per share is
calculated based upon weighted-average number of outstanding common shares for
the period. Diluted earnings per share is calculated based upon weighted-average
number of outstanding common shares, plus the effect of dilutive stock options.

The net loss per common share for the years ended December 31, 1999, 1998 and
1997 is based on the weighted average number of shares of common stock
outstanding during the periods. Potentially dilutive securities including
options, warrants and convertible preferred stock have not been included in the
calculation of the net loss per common share as their effect is antidilutive.
Consequently, there is no difference between the basic and dilutive net loss per
common share for any of the periods presented and none of the prior periods were
required to be restated. For purposes of this calculation, net loss in 1999,
1998 and 1997 has been adjusted for accumulated and/or paid dividends on the
Preferred Stock.

COMPREHENSIVE INCOME

SFAS No. 130, Reporting Comprehensive Income, requires that the Company
disclose, either in the income statement or in a separate financial statement,
net income as currently reported and other components of comprehensive income.
Comprehensive income is defined as the change in stockholders' equity during a
period resulting from transactions and other events and circumstances from
non-owner sources. For the years ended December 31, 1999, 1998 and 1997 the
Company did not have any components of comprehensive income as defined in SFAS
No. 130.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the financial statements and
the amount of revenue and expense reported during the period. Actual results
could differ from those estimates.

2.  STOCKHOLDERS' EQUITY

CONVERTIBLE PREFERRED STOCK

On August 16, 1999, the Company received $1,775,000 for 17,750 shares of Series
G Preferred Stock from several institutional and accredited individual investors
following the 10 day stockholder notification period required by the NASD prior
to the sale. On September 15, 1999, the Company received an additional $325,000
for 3,250 shares of Series G Preferred Stock, for total proceeds of $2,100,000.
Each share of Series G Convertible Preferred Stock was priced at $100 per share.
Each share can be converted at any time by the holder into common stock at a
price of $0.50 per share, subject to certain antidilution adjustments. Each
share of Preferred Stock also receives a common stock warrant, exercisable for
12 months, that allows the holder to acquire 200 shares of PPTI common stock at
a price of $0.50 per share.

Between April 1 and April 15, 1999, the Company received approximately $508,000
from the exercise of redeemable, publicly traded, warrants to purchase common
stock originally issued as part of PPTI's initial public offering. Following the
close of business on April 15, the remaining unexercised redeemable, publicly
traded, warrants expired. On May 12, 1999, the Company received approximately
$416,000 from the exercise of warrants to purchase common stock issued in
conjunction with the private placement of the Company's Series E Convertible
Preferred Stock.

In April and May of 1998, the Company raised approximately $5.4 million from the
sale of 54,437 shares of the Company's Series E Convertible Preferred Stock
("Series E Stock") priced at $100 per share, with warrants to purchase an
aggregate of 3,266,250 shares of common stock to a small group of institutional
and accredited investors. In connection with this transaction, the Company
recorded a non-cash "imputed dividend" expense of $3,266,250 in order to account
for the difference between the fair market value of the common stock and the
conversion price of the preferred stock into common stock.

Each share of Series E Stock is convertible at any time at the election of the
holder into 80 shares of common stock at a conversion price of $1.25 per share,
subject to certain antidilution adjustments. This registration became effective
on October 3, 1998. As of December 31, 1999, 11,650 shares of Series E Stock had
been converted into 932,000 shares of the Company's common stock.

2.  STOCKHOLDERS' EQUITY (continued)

Each share of Series E Stock received two common stock warrants. One warrant is
exercisable at any time for 40 shares of common stock at an exercise price of
$2.50 per share, and expires approximately 18 months after the close of the
offering; the other warrant is exercisable at any time for 20 shares of common
stock at an exercise price of $5.00 per share, and expires approximately 36
months after the close of the offering. In addition, an 18 month warrant to
acquire 200,000 common shares exercisable at $2.50 per share and a 36 month
warrant to acquire 100,000 common shares exercisable at $5.00 per share has been
issued as a finder and document review fee paid to a lead investor. An 18 month
warrant to acquire 32,000 common shares exercisable at $2.50 per share, a 24
month warrant to acquire 16,000 common shares exercisable at $5.00 per share,
and 5 year warrants to acquire an aggregate of 25,200 common shares exercisable
at $2.50 per share were issued to certain persons for service as finders in
relation to the private placement.

In connection with the above private placement, the Company issued 26,420 shares
of its Series F Convertible Preferred Stock ("Series F Stock") in exchange for
the same number of shares of outstanding Series D Convertible Preferred Stock
("Series D Stock").

Each share of Series D and F Stock earns a cumulative dividend at the annual
rate of $10 per share, payable if and when declared by the Company's Board of
Directors, in the form of cash, common stock or any combination thereof. The
Series D and F Stock is convertible into common stock after two years from the
date of issuance at the holder's option. The conversion price at the time of
conversion is the lesser of $3.75 or the market price. The Series D and F Stock
is redeemable at the Company's option after four years from the date of
issuance. Automatic conversion of all of the Series D and F Stock will occur if:
(a) the Company completes a public offering of common stock at a price of $2.50
or higher; or (b) the holders of a majority thereof elect to convert. The
Company has the option to demand conversion of the Series D and F Stock if the
average market price of its common stock equals or exceeds $5.00 per share over
a period of twenty business days. The Series D and F Stock have preference in
liquidation of $100 per share plus accumulated dividends.

The Series E Stock is convertible, at the option of the holder, into shares of
the Company's common stock, subject to anti-dilution adjustments, and has a
preference in liquidation of $100 per share, but only after any preference is
paid or declared set apart for the Series D Stock. Holders of the Series E Stock
are entitled to receive dividends when and if declared by the Board of
Directors; however, no such dividends will be declared or paid on the Series E
Stock until the preferential cumulative dividends on the Series D and F Stock
have been fully

occur if: (a) the Company completes a public offering of common stock at a price
of $7.50 or higher; or (b) the holders of more than 75% of outstanding Series E
Stock elect to convert.

The Series D, E and F Preferred Stock has been designated as non-voting stock.

STOCK OPTION PLANS

In September 1996 the Company established the Protein Polymer Technologies,
Inc., Employee Stock Purchase Plan ("Plan"). The Plan commenced January 2, 1997,
and allows for offering periods of up to two years with quarterly purchase dates
occurring the last business day of each quarter. The purchase price per share is
generally calculated at 85% of the lower of the fair market value on an eligible
employee's entry date or the quarterly purchase date. The maximum number of
shares available for issuance under the Plan is 500,000; an eligible employee
may purchase up to 5,000 shares per quarter. The Plan Administrator consists of
a committee of at least two non-employee directors of the Company. The Board may
modify the Plan at any time. During 1999, a total of 19,429 shares were
purchased under the Plan at prices ranging from $0.79 to $1.06. The value of
shares issued under the Plan as calculated in accordance with Statement 123 is
not significant and is not included in the following pro forma information.

In June 1996, the Company adopted the 1996 Non-Employee Directors Stock Option
Plan ("1996 Plan"), which provides for the granting of nonqualified options to
purchase up to 250,000 shares of common stock to directors of the Company. Such
grants of options to purchase 5,000 shares of common stock are awarded
automatically on the first business day of June during each calendar year to
every Participating Director then in office, subject to certain adjustments. No
Participating Director is eligible to receive more than one grant per year. The
purchase price of each option is set at the fair market value of the common
stock on the date of grant. Each option has a duration of ten years, and is
vested and exercisable six months after the grant date. The Board (or a
designated committee of the Board) administers the 1996 Plan. At December 31,
1999, 130,000 options to purchase have been granted under the 1996 Plan.

The Company adopted the 1992 Stock Option Plan which provides for the issuance
of incentive and non-statutory stock options for the purchase of up to 1,500,000
shares of common stock to its key employees and certain other individuals. The
options will expire

ten years from their respective dates of grant. Options become exercisable
ratably over periods of up to five years from the dates of grant. At December
31, 1999, options to purchase 527,000 shares of common stock were exercisable,
and 212,000 shares were available for future grant.

The Company adopted the 1989 Stock Option Plan which provided for the issuance
of incentive and non-statutory stock options for the purchase of up to 500,000
shares of common stock to key employees and certain other individuals. The 1989
Stock Option Plan expired as of March 17, 1999. Options granted in the plan
became exercisable ratably over periods of up to five years from the date of
grant. At December 31, 1999, options for 365,000 shares were exercisable.

Since inception, the Company has granted non-qualified options outside the
option plans to  employees, directors and consultants of the Company. At
December 31, 1999, options for 130,000 shares were exercisable.

The following table summarizes the Company's stock option activity:

The exercise prices for options outstanding as of December 31, 1999 range from
$0.22 to $0.84. The weighted average remaining contractual life of these options
is approximately 7.20 years.

STATEMENT 123 PRO FORMA INFORMATION

Pro forma information regarding net loss is required by SFAS No. 123, and has
been determined as if the Company had accounted for its employee stock options
under the fair value method prescribed by SFAS No. 123, using the Black-Scholes
option pricing model. The fair value was estimated using the following
weighted-average assumptions: a risk free interest rate of 5.50% for 1999, 6.00%
for 1998 and 6.43% for 1997; a volatility factor of the expected market price of
the Company's common stock of 100% for 1999, 89% for 1998 and 102% for 1997;
expected option lives of 5 years for 1999, 5 years for 1998, and 8 years for
1997; and no dividend yields for all years.

The Black-Scholes option valuation model was originally developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the expected life of the options. The Company's pro
forma information is as follows:

2.  STOCKHOLDERS' EQUITY (continued)

The pro forma effect on net loss for 1999, 1998 and 1997 is not representative
of the pro forma effect on net loss in future years because it does not take
into consideration pro forma compensation expense from option grants made prior
to 1995.

3.  STOCKHOLDER PROTECTION AGREEMENT

In 1997, the Board of Directors of the Company adopted a Stockholder Protection
Agreement ("Rights Plan") that distributes Rights to stockholders of record as
of September 10, 1997. The Rights Plan contains provisions to protect
stockholders in the event of an unsolicited attempt to acquire the Company. The
Rights trade together with the common stock, and generally become exercisable
ten business days after a person or group acquires or announces the intention to
acquire 15% or more of the outstanding shares of the Company's common stock,
with certain permitted exceptions. The Rights then generally allow the holder to
acquire additional shares of the Company's capital stock at a discounted price.
The issuance of the Rights is not a taxable event, does not affect the Company's
reported earnings per share, and does not change the manner in which the
Company's common stock is traded.

4.  COMMITMENTS

The Company leases its office and research facilities totaling 21,000 square
feet under an operating lease, which expires in May 2005. The facilities lease
is subject to an annual escalation provision based upon the Consumer Price
Index. The lease provides for deferred rent payments; however, for financial
purposes rent expense is recorded on a straight-line basis over the term of the
lease. Accordingly, deferred rent in the accompanying balance sheet represents
the difference between rent expense accrued and amounts paid under the lease
agreement.

Cost and accumulated depreciation of equipment held under capital leases as of
December 31, 1999 was $279,497 and $149,483, respectively. The carrying amount
of the Company's obligations under its capital lease agreements approximate
their fair value and the implicit interest rate approximates the Company's
borrowing rate.

Rent expense was approximately $417,000, $442,633, $412,000, and $3,637,633 for
the years ended December 31, 1999, 1998 and 1997 and for the period July 6, 1988
(inception) through December 31, 1999, respectively.

5.  INCOME TAXES

At December 31, 1999, the Company had net operating loss carryforwards of
approximately $30,589,000 for federal income tax purposes, which may be applied
against future income, if any, and will begin expiring in 2004 unless previously
utilized. In addition,

5.  INCOME TAXES (continued)

the Company had California net operating loss carryforwards of approximately
$12,249,000. The California tax loss carryforwards continue to expire. The
difference between the tax loss carryforwards for federal and California
purposes is attributable to the capitalization of research and development
expenses for California tax purposes, the required 50% limitation in the
utilization of California loss carryforwards, and the expiration of certain
California tax loss carryforwards.

The Company also has federal and California research and development tax credit
carryforwards of approximately $1,043,000 and $478,000, respectively, which will
begin expiring in 2004 unless previously utilized.

As a result of an ownership change that occurred in January 1992, approximately
$2,700,000 of the Company's federal net operating loss carryforwards will be
subject to an annual limitation regarding utilization against taxable income in
future periods. However, the Company believes that such limitations will not
have a material impact upon the utilization of the carryforwards.

Significant components of the Company's deferred tax assets as of December 31,
1999 are shown below. A valuation allowance of $12,867,000 has been recognized
to offset the deferred tax assets as realization of such assets is uncertain.

6.  EMPLOYEE BENEFITS PLAN

On January 1, 1993, the Company established a 401(k) Savings Plan for

7.  SUBSEQUENT EVENTS

Between January 1 and February 29, 2000, the Company received approximately $3.5
million in cash and receivables from license and development agreements, the
sale of the Company's cell culture business, and the exercise of common stock
warrants.

FEMCARE AGREEMENTS

On January 26, 2000, PPTI and Femcare Ltd. ("Femcare"), headquartered in
Nottingham, Great Britain, executed three related agreements involving the grant
of a license to Femcare to register and market PPTI's urethral bulking agent for
the treatment of female stress urinary incontinence in Europe and Australia. In
addition to the License and Development Agreement, PPTI agreed in a separate
Supply Agreement to provide final product to Femcare, and if unable to do so,
agreed to make the manufacturing methods and materials available to Femcare as
specified in a separate Escrow agreement.

In addition to agreeing to purchase the final product from PPTI for a defined
percentage of the revenues received by Femcare from the sale of the incontinence
product, Femcare agreed to pay PPTI an upfront license fee of $1 million in two
installments and agreed to pay PPTI a royalty on revenues received from the sale
of the incontinence product. The agreements specify the performance benchmarks
and timelines for each party, the definition of yearly minimum royalties and
minimum product purchases, and the methods and procedures for determining
product manufacturing requirements.

The license grant from PPTI to Femcare is for the greater of 20 years or the
date upon which the last patent included within the license grant for the
territories covered expires, subject to meeting various sales requirements, and
is exclusive in the territories covered, subject to certain conditions being
maintained. The parties agreed to cooperate extensively in the clinical testing
and the registration of the product with the appropriate governmental
authorities.

from Sanyo $355,000 (less associated expenses) for the license, including
assignment of the ProNectin(R) and SmartPlastic(R) trademarks and transfer of
remaining product inventory. The agreement remains in effect until the last
patent included within the license grant expires.


EXERCISE AND EXCHANGE OF SERIES G WARRANTS

During February 2000, holders of warrants issued in connection with the sale of
Series G Preferred Stock exercised their warrants to purchase common stock which
were due to expire in September, 2000. The exercise price was $0.50 per share.
As an inducement to exercise the warrant early, the Company offered each holder
a new one year warrant for a similar number of shares at an exercise price of
$1.50 per share. As a result the Company raised $2.1 million (less offering
expenses). The newly issued warrants will expire on the last day of February
2001.

     (b)   If the total royalty payable to PPTI by FEMCARE for the first
           Marketing Year and each subsequent Marketing Year is less than the
           applicable "Minimum Royalty" for that Marketing Year, FEMCARE shall
           within 90 days of the end of each such Marketing Year pay to PPTI
           (subject to paragraph (e) of this Article 4.02) a sum equal to the
           applicable Minimum Royalty less the actual royalty payable. At any
           time after the fifth Marketing Year, FEMCARE may notify PPTI that it
           is not going to make such payment in respect of any Marketing Year
           commencing after such fifth Marketing Year in which case the license
           granted pursuant to clause 2.01 shall at the expiry of such 90 day
           period become non-exclusive to FEMCARE for the remainder of the term
           of this Agreement.

           The applicable Minimum Royalty shall be as follows:

           Marketing Year                Minimum Royalty

               First                     ***

               Fifth and thereafter      ***

     Provided that if the rate of royalty payable under Article 4.02 is reduced
     pursuant to any provision of this Agreement or FEMCARE is permitted by this
     Agreement to set off or deduct any monies against any royalty payable to

     rate of royalty had not been so reduced and such set off or deduction had
     not been made.

<PAGE>

     Provided further that in any relevant Marketing Year such applicable
     Minimum Royalty shall be reduced by the extent to which FEMCARE failed to
     sell or procure that sale of sufficient Products to avoid having to pay
     such Minimum Royalty directly as a result of any material breach of this
     Agreement or the Supply Agreement by PPTI (and for this purpose force
     majeure under either Agreement which prevents PPTI from being in breach
     thereof shall be disregarded, and in the case of a force majeure affecting
     FEMCARE or its performance on  which such Minimum Royalty for such
     Marketing Year depends is affected by the force majeure, the Minimum
     Royalty shall be reduced by such fair amount.

     Provided, however, that no Minimum Royalty shall be payable in respect of
     any period during which Product cannot be Commercialized as a result of any
     inherent defect in the Product, any Recall required by any applicable
     regulatory body that is not specific to identified Product lots that are
     replaced within a reasonable period of time, or the Product being found to
     not be safe for use in humans.

     (c)   If the applicable royalty rate exceeds the permissible rate
           established in a Territory for royalty payments in that Territory or
           royalty remission from that Territory, as the case may be, the rate
           of royalty shall not exceed the established permissible rate and
           FEMCARE shall pay the difference between the royalty due and the
           royalty at the established permissible rate unless said payments made
           outside the Territory are illegal. In such event, the parties shall
           negotiate in good faith such equitable adjustments to other payments
           and financial obligations as may be appropriate so that the parties
           realize the intended benefits of this Agreement.

     (d)   Any Affiliate of FEMCARE may pay any royalty obligations of FEMCARE
           under this Agreement directly to PPTI with the same effect as if the
           payment had been made by FEMCARE.

     (e)   All payments under this Agreement shall be made without deduction of
           any taxes, charges, or duties except for such taxes, charges or
           duties which are required under any applicable laws to be deducted.
           Any tax deducted by FEMCARE or

                                       18
<PAGE>

           any Affiliate of FEMCARE under the laws of any foreign country for
           the account of PPTI shall be promptly paid to the proper governmental
           authority, and FEMCARE or its Affiliates shall furnish PPTI with
           proof of payment of such tax together with official or other
           appropriate evidence issued by the appropriate governmental authority
           sufficient to enable PPTI to document claim for income tax credit in
           respect to any sum so deducted. Any such tax required to be withheld
           shall be an expense of and borne solely by PPTI.

     (f)   FEMCARE shall keep accurate books and records of all payments due to
           PPTI. Said books of account shall be kept at FEMCARE's principal
           place of business or the principal place of business of an
           appropriate Affiliate to which this Agreement relates.

     (g)   PPTI shall have the right to nominate an independent accountant
           acceptable to and approved by FEMCARE (which approval shall not be
           unreasonably withheld) who shall have access to FEMCARE's records on
           reasonable notice during reasonable business hours for the purpose of
           verifying, at PPTI's expense (except as provided below), the royalty
           payable as provided for in this Agreement for the three preceding
           years, but this right may not be exercised more than once in any
           year. PPTI shall solicit or receive only information relating to the
           accuracy of the royalty report and the royalty payments made. Any
           underpayment of royalty shall be paid within thirty (30) days of the
           delivery of a detailed written accountants report to FEMCARE. Any
           overpayment of royalty shall be credited to the next royalty payment
           due from FEMCARE. If no further royalty payments will be due then a
           refund will be made within sixty (60) days of the audit. If the
           accountant's report shows an underpayment of royalties of five
           percent (5%) or more, FEMCARE shall reimburse PPTI for all cost and
           expense of the accountant's report.

     (h)   FEMCARE shall deliver to PPTI written reports of Net Sales during the
           preceding Calendar Quarter on or before the thirtieth (30th) day
           following the end of each Calendar Quarter. Such reports shall
           include a calculation of the earned royalty due and shall be
           accompanied by the monies due. If no earned royalties are due, then
           FEMCARE shall indicate such on its written report.

      that each party can report such experience to the other party pursuant to
      the provisions hereunder.

13.01 (a)  Subject to Article 13.02(a) PPTI agrees faithfully, at its sole
           expense to diligently prosecute to (and thereafter maintain) all
           patents applications for Patents referred to in paragraph (a) of the
           definition of "Patents" in the United States and, when reasonable

           or the like covering patentable technology disclosed in the Patents
           in the United States and within any applicable time limits to file
           foreign corresponding applications in the Territories (unless
           otherwise agreed in writing by FEMCARE) and to prosecute the same to
           grant and thereafter maintain the same.

      (b)  PPTI shall have the duty and responsibility to pay when due for
           payment all taxes, maintenance fees and annuities on the Patents and
           to maintain in force all patents within the Patents granted in the

      (c)  PPTI shall within thirty (30) days of mailing or receipt, provide
           FEMCARE with copies of all future filed patent applications relating
           to the Patents and, upon request, all correspondence from and to
           patent offices worldwide relating to both the Patents and future
           filed patent applications, re-examinations, reissues or the like.

13.02 (a) If PPTI, in its discretion, decides not to comply with any of the
          actions required to be taken by it under Article 13.01(a) and notifies
          FEMCARE in writing accordingly (such notice to specify clearly the
          countries in respect of which it is not going to take such actions) at
          least three months before the expiration of any material time period
          in respect of such actions, PPTI will be released from its obligations
          thereunder in respect of the actions so notified. PPTI shall so notify
          FEMCARE and FEMCARE shall, in its sole discretion, have the right to
          elect to assume the prosecution of such patent application on behalf
          of PPTI in respect of any such actions (including for the avoidance of
          doubt filing any applicable patent applications and prosecuting to
          grant any applicable patents and thereafter maintaining such patents)
          and PPTI shall co-operate fully and promptly with FEMCARE in the
          taking of any such actions by it.

                                       34
<PAGE>

      (b)  If FEMCARE so elects, it shall pay the costs and expenses of taking
           such actions and, notwithstanding anything in Section 4.02 to the
           contrary, FEMCARE's obligation to pay a royalty to PPTI in such
           country which is a Territory under Article 4 shall be reduced from
           *** to no less than *** until FEMCARE shall have recovered all costs
           and expenses associated with filings, prosecuting, issuing and
           maintaining said patent applications or patent(s).

      (c)  If the country to which paragraph (b) of this Article 13.02 is the
           United States FEMCARE shall be entitled to deduct all costs and
           expenses as aforesaid from any sums payable to PPTI under this
           Agreement until they have been reimbursed in full.

      (d)  PPTI shall not be deemed to be in breach of this Agreement for
           failing to comply with Article 13.01(a) to the extent that it fails
           to take any actions properly notified to FEMCARE pursuant to Article
           13.02(a).

13.03 (a)  The parties agree to cooperate in order to avoid loss of any rights
           which may otherwise be available to the parties under the U.S. Drug
           Price Competition and Patent Term Restoration Act of 1984, the
           Supplementary Certificate of Protection of the Member States of the
           European Common Market and other similar measures in any other
           country in the Territories.

      (b)  Without limiting the foregoing, PPTI agrees to notify FEMCARE
           promptly upon receipt of any PMA approval to Commercialize Product in
           the United States and PPTI agrees to file an application for patent
           extension in the U.S. Patent and Trademark Office within the sixty
           (60) day period following the receipt of such PMA approval.

                                       35
<PAGE>

14.01 (a)  If, as a result of the manufacture or Commercialization of the
           Product in the Territories pursuant to this Agreement and the Supply
           Agreement, PPTI and its Subsidiaries or FEMCARE and/or its
           Affiliates, distributors or sub-licensees, are sued for patent
           infringement or infringement of other intellectual property rights or
           threatened with such a lawsuit or other action by a third party, PPTI
           and FEMCARE shall promptly meet to analyze the infringement claim and
           avoidance of same.

      (b)  If following such meeting the parties fail to agree on a joint
           program of action, including how the costs of any such action are to
           be borne and how any damages or other sums received from such action
           are to be distributed, then FEMCARE shall be entitled to take action
           against the third party at its sole expense and it shall be entitled
           to all damages or other sums received from such action. PPTI shall
           agree to be joined in any suit to enforce such rights subject to
           being indemnified and secured in a reasonable manner as to any costs,
           damages, expenses or other liability and shall have the right to be
           separately represented by its own counsel at its own expenses.

      (c)  If it is necessary to obtain a license from such third party, PPTI
           and FEMCARE in negotiating such a license shall in the extent
           practicable use their reasonable efforts to minimize the license fees
           and/or royalty payable to such third party.

      (d)  If FEMCARE or its Affiliates, distributors or sub-licensees shall be
           obligated to pay a license fee and/or royalty to a third party under
           such licence as the result of the Commercialization of the Product or
           the use of Patents or Know-How then PPTI shall elect within ten (10)
           days of the execution of the license with such third party to:

           (i)     pay all fees and expenses associated with obtaining and
                   maintaining the license; or

           (ii)    to have the royalties specified in Article 4.02 reduced by
                   ***.

      (e)  FEMCARE shall be entitled to deduct from up to one-half of the
           royalties payable under clause 4.02 any sums paid to third parties
           (including without limitation damages, payments in settlement of
           litigation and reasonable cost and expenses incurred in relation to
           any alleged or actual infringement of third party rights in the
           manufacture or

           Commercialization of any product; provided that such payments are
           specifically approved, in advance, by PPTI, such approval to not be
           unreasonably withheld or delayed).

14.02 (a)  In the event that there is infringement of a Patent involving the
           Product by a third party in the Territories, PPTI and FEMCARE shall
           notify each other in writing to that effect immediately upon becoming
           aware of the same, including if practicable with said written notice
           evidence establishing a case of infringement by such third party.

      (b)  FEMCARE shall have the right, in its sole discretion, but not the
           obligation to bring such suit at its own expense and in its own name,
           if possible, or jointly in its name and in the name of PPTI or if
           necessary in PPTI's sole name.

      (c)  FEMCARE shall bear all the expenses of any suit brought by it and
           shall retain all damages or other monies awarded or received in
           settlement of such suit; provided, however, that at its option
           exercised by notice in writing to FEMCARE before it commences such
           suit PPTI may contribute to the expenses of any such suit and, in
           such event, FEMCARE and PPTI shall share proportionately to their
           respective contributions all damages or other monies awarded or
           received in settlement of such suit.

      (d)  PPTI will cooperate with FEMCARE in any such suit and shall have the
           right to consult with FEMCARE and, if it elects pursuant to the
           proviso to paragraph (c) of this Article, to be separately
           represented by its counsel at its own expense.

14.03 (a)  In the event that there is infringement of a patent of a Joint
           Invention jointly owned by the parties outside the grant provided to
           FEMCARE under Article 3.01 by a third party, PPTI and FEMCARE shall
           notify each other in writing to that effect immediately upon becoming
           aware of the same, including if practicable with said written notice
           evidence establishing a case of infringement by such third party.

                                       37
<PAGE>

      (b)  PPTI and FEMCARE shall meet to analyze the infringement claim, the
           evidence of same and attempt to agree upon a suitable approach for
           addressing said infringement.

15    ARBITRATION OF DISPUTES

15.01 Excepting only actions and claims relating to actions commenced by a third
      party against PPTI or FEMCARE (including, without limitation, for injuries
      caused by a Product or in respect to a trademark or patent infringement
      claim), any controversy or claim arising out of or relating to the terms
      and conditions of this Agreement, or the decision to agree upon these
      terms, or the breach thereof, including questions of validity,
      infringement, or termination hereof, shall be settled exclusively by
      arbitration in accordance with the rules of the American Arbitration
      Association. If such controversy or claim relates to patent validity or
      infringement, then the Patent Arbitration Rules of the AAA shall apply;
      otherwise the International Arbitration Rules of the AAA shall apply.
      Notwithstanding the foregoing to the contrary or in the arbitration rules
      invoked or in this Section 15, the parties retain the right to request a
      judicial authority to invoke interim measures of protection, and such
      request shall not be deemed incompatible with this agreement to arbitrate
      or a waiver of the right to arbitrate.

15.02 There shall be one (1) arbitrator to be mutually agreed upon by the
      parties and to be selected from the Regional Panel of Distinguished
      Neutrals. If the parties are unable to agreeupon such an arbitrator who is
      willing to serve within ten (10) days of receipt of the demand by the
      other party, the parties shall within three (3) days select one of the
      five largest international public accounting firms (excluding those
      providing services to the parties) and engage the managing partner or
      senior officer of its New York City office to designate a partner of such
      firm to serve as the arbitrator. Failing that, then the AAA shall appoint
      an arbitrator willing to serve from the Regional Panel of Distinguished
      Neutrals, or if no such panel exists, then from an appropriate AAA panel.
      It shall be the duty of the arbitrator to set dates for preparation and
      hearing of any dispute and to expedite the resolution of such dispute.

                                       38
<PAGE>

15.03 (a)  The arbitration shall be held in the City of New York, State of New
           York, U.S.A. and the arbitrator shall apply the substantive law of
           Delaware except that the interpretation and enforcement of this
           arbitration provision shall be governed by the Federal Arbitration
           Act.

      (b)  The arbitrator shall permit and facilitate discovery, which will be
           conducted in accordance with the Federal Rules of Civil Procedure,
           taking into account the needs of the parties and the desirability of
           making discovery expeditious and cost-effective.

      (c)  The arbitrator will set a discovery schedule with which the parties
           will comply and attend depositions if requested by either party.

      (d)  The arbitrator will entertain such presentation of sworn testimony or
           evidence, written briefs and/or oral argument as the parties may wish
           to present, but no testimony or exhibits will be admissible unless
           the adverse party was afforded an opportunity to examine such witness
           and to inspect and copy such exhibits during the pre-hearing
           discovery phase.

      (e)  The arbitrator shall among his other powers and authorities, have the
           power and authority to award interim or preliminary relief.

      (f)  The arbitrator shall not be empowered to award either party exemplary
           or punitive damages or any enhanced damages for willful infringement
           and the parties shall be deemed to have waived any right to such
           damages.

      (g)  A qualified court reporter will record and transcribe the proceeding.

      (h)  The decision of the arbitrator will be in writing and judgment upon
           the award by the arbitrator may be entered in any court having
           jurisdiction thereof.

      (i)  Prompt handling and disposal of the issue is important. Accordingly,
           the arbitrator is instructed to assume adequate managerial initiative
           and control over discovery and other aspects of the proceeding to
           schedule discovery and other activities for substantially continuous
           work, thereby expediting the arbitration as much as is deemed
           reasonable to him, but in all events to effect a final award within
           365 days of the arbitrator's selection or appointment and within 20
           days of the close of evidence.

      (j)  The proceedings shall be confidential and the arbitrator shall issue
           appropriate protective orders to safeguard both parties' confidential
           information.

                                       39
<PAGE>

      (k)  The fees of the arbitrator and the AAA shall be paid as designated by
           the arbitrator or, if he shall not so designate, they shall be split
           equally between the parties.

           previously incorporated in the IDE *** or disclosed to FEMCARE which
           indicates that it may not be safe for administration to humans or

      property" as defined under Section 101(60) of the Bankruptcy Code. The
      parties agree that a licensee of such rights under this Agreement, shall

      property and all embodiments of such intellectual property, and same, if
      not already in its possession, shall be promptly delivered to licensee (i)
      upon any such commencement of a bankruptcy proceeding upon written request
      therefor by the licensee, unless licensor elects to continue to perform
      all of its obligations under this Agreement, or [(ii) if not delivered
      under (i) above, upon the rejection of this Agreement by or on behalf of
      licensor upon written request therefor by licensee.

                                SUPPLY AGREEMENT


     THIS SUPPLY AGREEMENT is made and entered into this day of by and between
PROTEIN POLYMER TECHNOLOGIES, INC., a Delaware corporation (" Supplier")and
FEMCARE UROLOGY LIMITED, a corporation under the laws of the United Kingdom and
Wales having offices at St. Peter's Street, Nottingham, NG7 3EN, England
("Purchaser").


                                  WITNESSETH:

     WHEREAS, Purchaser and Supplier are party to that certain License and
Development Agreement dated January 26, 2000 (the "License Agreement")pursuant
to which Purchaser has been granted an exclusive license to Commercialize the
Product in the Territories in the Field.

     WHEREAS, pursuant to the License Agreement, all of the Product that is
marketed by Purchaser is to be manufactured by Supplier or by another company
selected by Supplier and approved by Purchaser for the term of the License
Agreement.

     WHEREAS, Supplier possesses and is further developing the Know-How and
Patents to commercially manufacture the Product.

     WHEREAS, Supplier desires to manufacture and sell to Purchaser, and
Purchaser desires to engage Supplier to manufacture and supply to it, the
Product, in each case subject to the terms and conditions of this Agreement.

     NOW, THEREFORE, in consideration of the mutual covenants contained herein
and for other good and valuable consideration, the receipt, sufficiency and
adequacy are hereby acknowledged, the parties hereto agree as follows:

     1.    PREAMBLES AND DEFINITIONS. The preambles set forth above are an
integral part of this Agreement and are incorporated herein by this reference.
All capitalized terms used but not defined in this Agreement shall have the
meanings ascribed thereto in the License Agreement.

     2.    SUPPLY AND PURCHASE OF PRODUCT.

     (a)   During the five year period beginning with the date of this
Agreement (the "Exclusive Term"), Purchaser hereby agrees to purchase and to
cause its Affiliates to purchase from Supplier or such person as Supplier shall
designate, the entire requirements of Product by Purchaser, its Affiliates,
distributors and sublicensees. After the expiration of the Exclusive Term,
Purchaser may, but shall not be required to purchase and to cause its Affiliates
to purchase Product from Supplier or Supplier's designee. All Product supplied
by Supplier pursuant to this Agreement shall be resold and distributed solely in
the Territories for use in the Field. The Purchaser and its Affiliates,
distributors and sublicensees shall not resell the Product to any person in the
Territories knowing or
<PAGE>

having reasonable basis to believe that such person intends to re-sell the
Product outside of the Territories or use or resell the Product outside of the
Field.

     (b)   Supplier agrees to manufacture, package, sell and ship or cause to be
manufactured, packaged, sold and shipped, the Product to Purchaser, in finished
*** units, subject to Purchaser satisfying its obligations hereunder. All
purchases by Purchaser or its Affiliates will be made by purchase orders issued
by Purchaser or such Affiliate to Supplier setting forth the quantities of
Product ordered and the anticipated delivery date. Quantities of Product shall
be identified by units.

     (c)   Purchaser shall provide to Supplier upon the commencement of the Term
and in all events not less than 120 days before the expected beginning of the
first Marketing Year and thereafter not less than 90 days prior to the
commencement of each subsequent Marketing Year a bona fide (based on a realistic
estimate of sales in the relevant Marketing Year) 12 month projection of
anticipated (not guaranteed) Product purchases by Calendar Quarter by Purchaser
and its Affiliates during the upcoming Marketing Year ("Annual Estimate").
Supplier shall have 15 days in which to review the Annual Estimate and advise
Purchaser as to whether or not it has the available capacity to manufacturer and
supply the Annual Estimate. Supplier shall use all reasonable efforts to put
itself in a position whereby it is able to agree with the Purchaser's Annual
Estimate for the applicable Marketing Year. If Supplier, having applied such
reasonable efforts, advises Purchaser that it cannot manufacture and supply
Product equal to the Annual Estimate, Supplier may arrange for a third party
manufacturer selected by it and approved by Purchaser, which approval shall not
be unreasonably withheld or delayed, to assist Supplier in the manufacturer and
supply of Product. If Supplier shall be unable to timely manufacture or have
manufactured Product equal to the Annual Estimate, Supplier and Purchaser shall
negotiate and adopt a revised Annual Estimate and in such negotiations the
Supplier shall use its reasonable efforts to reduce the Purchaser's original
Annual Estimate by the smallest number of units reasonably practicable. In such
a case, if the revised Annual Estimate is less than the Minimum Purchase
requirement for the subject Marketing Year (as expressed in units), the Minimum
Purchase requirement for that Marketing Year shall be reduced to the dollar
amount (using the table in Section 5(a))corresponding to the number of units in
the revised Annual Estimate and a corresponding adjustment shall be made for the
Minimum Royalty payable under the License Agreement.

     (d)   Purchase orders for the Product shall be placed with Supplier at
least 90 days prior to Purchaser's anticipated delivery date. All Product will
be purchased in quantities of not less than one-twelfth (1-12th) of the Annual
Estimate unless otherwise requested in advance by Purchaser and agreed to by
Supplier, which agreement shall not be unreasonably withheld or delayed.

submitted in accordance with this Agreement shall be firm and binding upon
Purchaser after acceptance by Supplier. Purchase orders for Product shall be
deemed acceptable to Supplier provided that the quantities and delivery dates do
not deviate materially from the Marketing Year Annual Estimate developed by
Purchaser. Purchase orders shall be deemed to have been accepted by Supplier
seven (7) calendar days after delivery of the purchase order to Supplier unless
within said seven (7) day period Supplier shall give notice to Purchaser of the
unacceptability of said purchase order for a reason for non-acceptance permitted
under this Agreement (which reason shall be set out in the notice).

     (e)   Supplier shall supply ordered Product as requested by Purchaser to
the extent that the purchase order does not exceed by an amount greater than
fifty percent (50%) from the corresponding month within the Annual Estimate.
Supplier shall use all reasonable efforts to fill each purchase order delivered
by Purchaser or its Affiliates within 90 days of delivery of such purchase order
or such lesser period of time and Purchaser and Supplier shall, in advance,
agree.

     3.    DELIVERY

     (a)   Delivery of Product to Purchaser and its Affiliates shall be F. O. B.

to Purchaser a copy of test results for each lot of Product supplied to
Purchaser or its Affiliates.

     (b)   Each of Supplier and Purchaser shall conduct such quality control
procedures and inplant quality control checks as it shall deem reasonably
necessary. Supplier shall use the same quality control procedures and checks as
it applies in the manufacturing of Product for its own use and sale. Purchaser

quality control testing, or provide that its Affiliates, distributors or sub-
licensees conduct quality control testing, within 30 days of delivery of Product

attention of Supplier any Product that does not meet Purchaser's audit or
quality control procedures and checks. Product lots that meet Supplier's quality
control requirements and which are not objected to by Purchaser within 30 days

     (c)   Each party agrees to notify the other within 48 hours of learning
of (i) the failure of any Product to meet standards found in said Product's
Regulatory Approval or (ii) third-party complaints pertaining to Product.

approach to the resolution of complaints lodged against other products marketed
by Purchaser and its Affiliates (subject to Supplier, as required by Purchaser's
quality control manual, providing Purchaser with any information in its
possession that may facilitate prompt and favorable resolution of any such
complaints and without limitation, within 72 hours of the delivery of the
complaint to Supplier). In the event that Purchaser cannot resolve such
complaint as aforesaid, Purchaser shall notify Supplier and the parties shall
jointly attempt to resolve the problem.
<PAGE>

     (d)   In the event that any governmental agency or authority issues a
recall or takes similar action in connection with any Product sold or

in a Territory, or Purchaser reasonably considers it necessary to recall
Product, Purchaser shall, within 24 hours, advise Supplier by telephone, e-mail
or facsimile transmission and Supplier and Purchaser shall agree on an
appropriate course of action. Purchaser shall assume complete responsibility for
conducting such recall; however, Supplier shall provide Purchaser with any
information that may be in Supplier's possession or control concerning the
manufacture of the Product which Purchaser reasonably may require to conduct
such recall. Supplier and Purchaser shall cooperate to identify and correct
deficiencies, if any, in the manufacture, shipment, storage or distribution of
the Product. In the event of such a recall or if Supplier requests Purchaser to

shall immediately cease all sales of such Product and take all appropriate
actions to recall such Product. Supplier shall bear the expenses of any recall
requested by it or resulting from (i) defective manufacture, packaging or

this Agreement, that causes such Product recall. Purchaser shall bear the
expenses of any other recall. For the purpose of this Agreement expenses of
recall include, without limitation, the expenses of notification and destruction
or return of the recalled Products, but not the expense or service fees
associated with salesmen's time which shall be borne by Purchaser.

     (e)   Supplier shall retain samples of all ingredients, packaging
materials, records and data as may be in accordance with the sample and record
retention policies which Supplier uses in connection with manufacture of Product
for its own account; provided such retention shall at all times be in accordance
with all applicable Regulatory Approvals, Quality System Regulations and IS0
9001 Standards. Purchaser shall have the right, from time to time, to review
Supplier's manufacturing procedures and operations and its records relating to
the manufacture and shipment of Product. No inspection or testing of Product by
Purchaser, or failure to test or inspect, shall relieve Supplier of its
obligations hereunder. Copies of any certificates, reports, test results or
other information produced by Supplier, or by a third party consultant or
contractor at Supplier's request, that directly relate to lots of Product sold
to Purchaser shall, upon the written request of Purchaser, be furnished to
Purchaser and may be relied upon by it.

     (f)   The parties recognize that the holder of or applicant for Regulatory
Approvals for a country may be required to submit information and file reports
to various governmental agencies on Product under clinical investigation,
Product proposed for Commercialization, or Commercialized Product. Consequently,
each party agrees to provide to the other within three (3) business days of the
initial receipt of a report of any adverse experience with Product that is
serious or unexpected. Serious adverse experience means any experience that
suggests a significant hazard, contraindication, side effect or precaution, or
any experience that is fatal or life threatening, is permanently disabling,

     5.    PRICE AND PAYMENT TERMS.

     (a)   Purchaser will pay the unit price for each accepted Product. The unit
price within each Marketing Year shall be the greater of that amount which is
equal to *** of Purchaser's Net Sales price per Unit or as follows:


     Marketing      ***
        Year

     First          ***

     Second         ***

     Third          ***

     Fourth         ***

     Fifth          ***


All prices of Product shall be stated in U. S. Dollars and all payments made
under this Agreement (or any invoice issued in accordance with this
Agreement) shall be paid in U. S. Dollars and shall be without deduction of any
taxes or other charges except as required by law. Per unit invoice pricing shall
be based on the number of units previously delivered (in accordance with the
first sentence of Section 3(a) above) during the Marketing Year and being
delivered under the purchase order then being filled net of any units returned
and scheduled to be returned by Purchaser to Supplier. All invoices for Products
sold to Purchaser and its Affiliates shall be the obligation of Purchaser.
However, any Affiliate of Purchaser may pay any invoice or account payable
obligation of Purchaser directly to Supplier with the same effect as if the
payment had been made by Purchaser.

     (b)   The unit price shall include manufacturing, packaging, and Supplier's
quality control measures as Supplier applies to Product used or sold by
Supplier. Purchaser shall provide to Supplier in writing the packaging and
labeling requirements for the Product, which requirements, when determined,
shall meet all applicable Quality System Regulations and IS0 9001 Standards
and/or such other lawful and appropriate standards as the parties may agree
upon, and shall become part of the Product specifications for the Product. Such
requirements shall be specified within a reasonable period of time prior to the
first shipment of Product in order to allow Supplier to be able to satisfy
Purchaser's requirements. In addition, from time to time upon reasonable prior
notice to Supplier, Purchaser may make changes to such packaging and labeling
specifications should

Purchaser determine such changes are necessary or desirable and subject to then
satisfying all applicable Regulatory Approvals. To the extent permitted under
applicable law, Purchaser shall credit Supplier as the licenser or manufacturer
of the technology used in the Product.

     (c)   The unit price as specified in Section 5(a) shall apply during the
first five (5) Marketing Years. Thereafter, not less than 60 days prior to the
end of the fifth Marketing Year, and not less than 60 days prior to the end of
every second Marketing Year thereafter, Supplier and Purchaser may agree to
revise any of the prices for the forthcoming marketing years. In no event shall
the price to be paid to Supplier by Purchaser and its Affiliates be less than
***of Purchaser's Net Sales price per unit in the Territory. If the average
number of units required per treatment procedure in the Clinical Efficacy Trials
exceeds ***, the parties shall (subject to Supplier increasing its or its
approved contract manufacturing capacity of Products to allow for the
consequential increase in demand) adjust the unit price and unit volume
increments per Marketing Year, and volume of product per unit, in a manner which
takes into account the assumptions used by the parties to determine the
Minimum Purchase requirement specified in Section 5(e).

     (d)   The terms of payment are net upon shipment of Product. Any invoice
not paid when due shall be subject to late and service charges equal to l-
1/2% per month of the amount past due. Notwithstanding anything in the foregoing
to the contrary, any purchase order submitted or to be filled within the last
four months of the term of this Agreement or the termination of Supplier's
obligations under this Agreement shall be accompanied by an unconditional,
irrevocable letter of credit issued by a banking institution having facilities
in New York City, New York that is reasonably acceptable to Supplier in the full
face amount of the extended price of the Product ordered, and payable to
Supplier or its assignee which letter of credit shall be drawable upon
presentment of the letter of credit and bills of lading evidencing delivery of
the Product pursuant to such purchase order.

     (e)   If for any Marketing Year Purchaser shall not have purchased from
Supplier the Minimum Purchase requirement for such Marketing Year, Purchaser
shall pay to Supplier within 45 days following the close of the applicable
Marketing Year the amount by which the applicable Minimum Purchase requirement
for the Product exceeds the actual revenue derived by Supplier from the sale of
Product to Purchaser. The Minimum Purchase requirement is as follows:

              Marketing Year            Minimum Purchases

              First                     ***

              Second                    ***

              Third                     ***

              Fourth                    ***

              Fifth                     ***

<PAGE>

     The parties agree that the Minimum Purchase requirements shall not apply in
any Marketing Year in which (i) the Minimum Royalty under the License Agreement
is not payable to Supplier due to Purchaser's affirmative election under Section
4.02(b) of the License Agreement, or (ii) the quantity of Product corresponding
to the Minimum Purchase requirement has been ordered by Purchaser but Supplier
has failed to timely till the accepted purchase orders required to be filled
within said Marketing Year or committed a breach of this Agreement that prevents
the Minimum Purchase requirements being achieved. In the event of (ii), if there
continues to be a delivery of Product to Purchaser, the Minimum Purchase
requirements shall be reduced by dollar amount corresponding to the number of
units of Product ordered by Purchaser for timely delivery on the Marketing Year
which are not delivered to Purchaser in such Marketing Year but if Supplier has
failed to deliver to Purchaser for six (6) months or more during the Marketing
Year, any Product ordered by Purchaser and scheduled for timely delivery within
the Marketing Year, the Minimum Purchase requirements for such Marketing Year
shall be waived and for the next Marketing Year the Minimum Purchase requirement
shall revert to that in effect for the immediately preceding Marketing Year (or
if in the two Marketing Years the Minimum Purchase requirements are the same,
the Minimum Purchase requirement shall be reduced by 20%) and a corresponding
adjustment shall be made to subsequent Marketing Years and to the Minimum
Royalty requirements under the License Agreement. Notwithstanding the forgoing,
the Minimum Purchase requirement shall be suspended during any period during
which Product cannot be Commercialized as a result of any inherent defect in the
Product, any Recall required by any applicable regulatory body that is not
specific to identified Product lots that are replaced within a reasonable period
of time, or the Product being found to not be safe for use in humans.

     6.    MARKETING AND TECHNICAL SUPPORT

     (a)   Supplier agrees to provide Purchaser (but not to its Affiliates or
distributors), with such reasonable technical support as Purchaser may from time

additional cost to Purchaser. To the extent appropriate, such data shall be
subject to the confidentiality obligations set forth in the License Agreement.

     (b)   Purchaser agrees to provide to Supplier copies of all training,
advertising and promotional materials for the Product, as those materials become
available, including translations thereof into the English language. Purchaser
agrees that all such materials shall be prepared in accordance with all
applicable laws and regulations.

     (c)   Supplier shall promptly refer to Purchaser all customer inquiries and
correspondence which Supplier receives from persons within a Territory in the
Field relating to the Product.

     10.   INDEMNIFICATION.

     (a)   Each party ("Indemnitor") agree to indemnify, defend and hold
harmless the other party ("Indemnitee") from and against all liabilities,
losses, costs, damages and expenses (excluding fees and disbursements of the
Indemnitee's counsel and court costs, except as provided below) caused by,
arising out of resulting from (i) the Indemnitor's gross negligence or willful
misconduct in carrying out its obligations under this Agreement, (ii) the
Indernnitor's failure to comply with any law or regulation applicable to the
performance of its obligations under this Agreement, (iii) Product seizures made
as a direct result of the Indemnitor's negligence, gross negligence or willful
misconduct in the performance of or failure to perform, its obligations under
this Agreement and any liabilities of Indernnitor in respect of recalls under
Article 4(d), and (iv) any labels or advertising used by the Indemnitor, in any
such case that is not based on any act or omission or alleged act or omission of
the Indemnitee. The indemnity provided above shall not extend to any
liabilities, losses, costs, damages or expenses caused by or resulting from or
arising out of any act or omission or breach of representation, warranty or
covenant of the Indemnitee.

     (b)   Each party agrees to give the other party prompt notice of any claim
or demand made or the institution of any suit or proceeding brought upon the
grounds referred to under this Section 10, and to permit the Indemnitor to
conduct the defense of any such claim, demand, suit, or proceeding, and to give
the Indemnitor all information in its possession which is pertinent to the
defense of any such claim, demand, suit or proceeding, and to give the
Indemnitor the authority and assistance appropriate or necessary to enable the
Indemnitor to carry on such defense and any appeal from a judgment or decree
rendered in any such suit or proceeding. However, nothing in this Section
10(b) will prevent the Indemnitee from engaging its own counsel in any such
matter and, if there shall exist a bona fide conflict between the rights and
interest of the indemnifying party and the indemnified party, from being
indemnified with respect to such engagement to the extent provided in this
Section 10.

     (c)   Without its prior consent, Supplier will not be responsible for or
bound by any compromise made by Purchaser in any matter in which Purchaser is

which Purchaser is indemnified by Supplier.

     (d)   The Indemnitee agrees to give the Indemnitor prompt notice of any
claim, demand, suit or proceeding asserted, made or brought against the
Indemnitee (including any claim, demand, suit or proceeding asserted, made or
brought by any governmental authority) for which the Indemnitor might be liable
under the foregoing provisions. However, the failure to give prompt notice shall
not relieve the Indemnitor from its obligations hereunder unless the failure to
give prompt notice has materially and adversely affected the Indemnitor's
defense of the claim or action.

     11.   PRODUCT LIABILITY INSURANCE.   Each of Supplier and Purchaser (and
each Affiliate of Purchaser purchasing and selling Product) shall at all times
during the term of this Agreement and for a period of 12 months after the
expiration or termination of this Agreement carry such products liability
(comprehensive general liability insurance) in such amounts and subject to such


                                       11
<PAGE>

requirements and restrictions as may be customary in the Territory (in the case
of Purchaser or its Affiliates)or in the United States (in the case of
Supplier).

     12.   ARBITRATION.

     (a)   Excepting only actions and claims relating to actions commenced by a
third party against Supplier or Purchaser (including, without limitation, for
injuries caused by a Product or in respect to a trademark or patent infringement
claims), any controversy or claim arising out of or relating to the terms and
conditions of this Agreement, or the decision to agree upon these terms, or the
breach thereof, including questions of validity, infringement, or termination
hereof, shall be settled exclusively by arbitration in accordance with the rules
of the American Arbitration Association. If such controversy or claim relates to
patent validity or infringement, then the Patent Arbitration Rules of the AAA
shall apply, otherwise the International Arbitration Rules of the AAA shall
apply. Notwithstanding the forgoing to the contrary or in the arbitration rules
invoked or in this Section 12, the parties retain the right to request a
judicial authority to invoke interim measures of protection, and such request
shall not be deemed incompatible with this agreement to arbitrate or a waiver of
the right to arbitrate.

     (b)   There shall be one (1) arbitrator to be mutually agreed upon by the
parties and to be selected from the Regional Panel of Distinguished Neutrals. If
the parties are unable to agree upon such an arbitrator who is willing to serve
within ten (10)days of receipt of the demand by the other party, the parties
shall within three (3) days select one of the five (5) largest international
accounting firms (excluding those providing services for the parties) and engage
the managing partner or senior officer of its New York City office to designate
a partner of such firm to serve as the arbitrator. Failing that, then the AAA
shall appoint an arbitrator willing to serve from the Regional Panel of
Distinguished Neutrals, or if no such panel exists, then from an appropriate AAA
panel. It shall be the duty of the arbitrator to set dates for preparation and
hearing of any dispute and to expedite the resolution of such dispute.

     (c)   The arbitration shall be held in the City of New York, State of New
York, U. S. A. and the arbitrator shall apply the substantive law of Delaware
except that the interpretation and enforcement of this arbitration provision
shall be governed by the Federal Arbitration Act. The arbitrator shall permit
and facilitate discovery, which will be conducted in accordance with the Federal
Rules of Civil Procedure, taking into account the needs of the parties and the
desirability of making discovery expeditious and cost-effective. The arbitrator
will set a discovery schedule with which the parties will comply and attend
depositions if requested by either party. The arbitrator will entertain such
presentation of sworn testimony or evidence, written briefs and/or oral argument
as the parties may wish to present; however, no testimony or exhibits will be
admissible unless the adverse party was afforded an opportunity to examine such
witness and to inspect and copy such exhibits during the pre-hearing discovery
phase. The arbitrator shall among his other powers and authorities, have the
power and authority to award interim or preliminary relief. The arbitrator shall
not be empowered to award either party exemplary, consequential or punitive
damages or any enhanced damages for willful infringement and the parties shall
be deemed to have waived any right to such damages. A qualified court reporter
will record and transcribe the proceeding. The decision of the arbitrator will
be in writing and judgment upon the award by the arbitrator may be entered in

                                       12
<PAGE>

any court having jurisdiction thereof. Prompt handling and disposal of the issue
is important. Accordingly, the arbitrator is instructed to assume adequate
managerial initiative and control over discovery and other aspects of the
proceeding to schedule discovery and other activities for substantially
continuous work, thereby expediting the arbitration as much as is deemed
reasonable to him, but in all events to effect a final award within 365 days of
the arbitrator's selection or appointment and within 20 days of the close of
evidence. The proceedings shall be confidential and the arbitrator shall issue
appropriate protective orders to safeguard both parties'confidential
information. The fees of the arbitrator and the AAA shall be paid as designated
by the arbitrator or, if he shall not so designate, they shall be split equally
between the parties.

     13.   ESCROW AGREEMENT.   Notwithstanding the Effective Date of this Supply
Agreement, Supplier agrees to place into escrow when and as required under the
Escrow Agreement of even date herewith sealed containers containing a copy of
the Escrow Materials (as defined in the Escrow Agreement) for the Product to be
held subject to the terms and conditions of the Escrow Agreement. Supplier
shall, upon placing the Escrow Materials into escrow, so notify Purchaser of
such fact in writing.

     14.   NOTICES.   Any notice provided for under this Agreement shall be
given by sending such notice to the noticed party by personal delivery, telecopy

                               ESCROW AGREEMENT


ESCROW AGREEMENT, dated as of January 26, 2000, among PROSPECTIVEPIERCING
LIMITED, to be known as FEMCARE UROLOGY LIMITED, corporation organized under the
laws of the United Kingdom and Wales, having its principal place of business at
St. Peters Street, Nottingham NG7 3EN, United Kingdom ("FEMCARE"), and PROTEIN
POLYMER TECHNOLOGIES, INC., a corporation with its principal office at 10655
Sorrento Valley Road, San Diego, California 92121 ("PPTI"), and the party
identified on Exhibit A attached hereto ("Escrow Agent").

     WHEREAS, in connection with the License and Development Agreement between
FEMCARE and PPTI ("License Agreement") and Supply Agreement between PPTI and
FEMCARE ("Supply Agreement"), each dated as of the date of this Escrow
Agreement, PPTI has agreed to enter into this Escrow Agreement pursuant to which
PPTI shall deposit into escrow, when required (i) aliquotes of the Master Cell
Bank and Working Cell Bank for the Product (as such term is defined under the
License Agreement) ("Sample", herein), and (ii) the current manufacturing and
quality control procedures with respect to the Sample being deposited, as well
as such other Know-How (as defined in the License Agreement), technical
specifications, instructions, processes and other intellectual property and
information as PPTI shall possess and as shall be necessary in order to allow
FEMCARE to manufacture and/or have manufactured for it the Product so licensed
(a "Process Description") and (iii) any written agreement  between PPTI and any
contract manufacturer engaged by PPTI to manufacture Product and a related
assignment and assumption agreement and letter of direction as provided in
Section 2 (c) below ("Toll Manufacturing Materials" and together with the
Process Descriptions and the Sample, collectively, the "Escrow Material");

     NOW, THEREFORE, the parties hereto agree as follows:

     1.    APPOINTMENT OF ESCROW AGENT. Within thirty (30) days after the
execution of this Agreement, FEMCARE shall select and appoint an Escrow Agent,
which appointment shall be subject to the consent of PPTI, such consent not to
be unreasonably withheld or delayed. The Escrow Agent must certify to the
parties that it has and will at all times during the term of the escrow liquid
nitrogen storage capabilities and that it will use such capabilities to hold the
Samples. Upon such appointment, the Escrow Agent shall execute a copy of Exhibit
A (duly filled in with the information specified thereon), whereupon the Escrow
Agent shall become a party to this Agreement.

     2.    DEPOSIT BY PPTI.

     (a)   Within ten (10) days after the appointment of the Escrow Agent, PPTI
will deposit in escrow with the Escrow Agent a sealed receptacle containing a
copy of the Process Description, which receptacle shall be held subject to the
terms and conditions of this Escrow Agreement.  The Process Description shall be
sufficiently clear and detailed that it can be readily followed and carried

                                       1
<PAGE>

out by a trained scientist and PPTI shall, upon placing the Process Description
into escrow, so notify FEMCARE of such deposit in writing, and provide to
FEMCARE a schedule of Process Description information so deposited. A FEMCARE
representative on the Advisory Board appointed under the License Agreement may
verify the Process Description information being deposited against the schedule.
The schedule shall constitute PPTI Know-How (as defined in the License
Agreement) and shall be kept confidential. PPTI agrees to update and keep
current, accurate and complete the Process Description on an annual basis or
more frequently if required to reflect procedures embodied in Regulatory
Approvals (as that term is defined in the License Agreement) or required to
assist in the manufacture of Product (and where appropriate, the term "Process
Description" shall include any such updated materials from time-to-time). PPTI
shall, upon each updating of the Process Description, so notify FEMCARE of such
fact in writing, and give it the same verification opportunity as is provided
above. FEMCARE may, at its sole cost and expense, obtain such insurance as it
deems reasonable and necessary regarding the Escrow Materials.

     (b)   Within ten (10) days after the appointment of the Escrow Agent, PPTI
will also deposit in escrow with the Escrow Agent a sealed receptacle containing
the Sample, which receptacle shall be held subject to the terms and conditions
of this Escrow Agreement.  PPTI shall, upon placing each Sample into escrow, so
notify FEMCARE of such deposit in writing.  PPTI agrees to replace the deposited
Sample with a newly-generated set of Sample if PPTI, based on quality control
testing of Product manufactured from cognate cells shall determine that the
cells in the Sample are not viable, in which case FEMCARE shall give its written
instructions pursuant to Article 4.  PPTI shall, upon each replacement of the
Sample, so notify FEMCARE of such deposit in writing and such replacement shall
be deemed the Sample for purposes of this Agreement.

     (c)   Within ten (10) days after the engagement by PPTI of a contract
manufacturer of Product, if any, PPTI will also deposit into escrow with the
Escrow Agent a sealed receptacle containing any written agreement for the
manufacture of Product between PPTI and such contract manufacturer, an
assignment and assumption of said written agreement by and between PPTI and
FEMCARE duly executed by PPTI (but not FEMCARE), and a letter of direction
addressed to the contract manufacturer informing it of the assignment of the
written agreement to FEMCARE and authorizing it to manufacture Product on behalf
of, and supply such Product directly to FEMCARE under said assigned written
agreement (the "Toll Manufacturing Materials"). Any deposit of Toll
Manufacturing Materials notwithstanding, PPTI shall not be obligate to continue
the engagement of any contract manufacturer or to keep in effect any written
agreement for the contract manufacture of Product, or fully comply with the
terms and conditions of any such written agreement. PPTI shall promptly notify
FEMCARE of any change in the Toll Manufacturing Materials and, when necessary,
shall replace Toll Manufacturing Materials with new, amended or additional Toll
Manufacturing Materials, and shall so notify FEMCARE in writing.

     3.    REPRESENTATION. PPTI represents that the Process Description will be
accurate and complete in all material respects, that in its reasonable opinion
the Process Description is sufficiently clear and detailed so that they can be
readily followed and carried out by a trained scientist to

                                       2
<PAGE>

manufacture the Product, and that the deposited Sample(s) (including any
replacement Sample deposited pursuant to Article 2) will be free of defects and
will be viable at the time of deposit.

     4.    CUSTODY; ACCESS. Escrow Agent agrees to accept deposit of the Escrow
Materials and to act as its custodian until the escrow is terminated pursuant to
the terms of this Escrow Agreement. Except as otherwise provided in this Escrow
Agreement, Escrow Agent shall not permit (i) any party access to the Escrow
Materials and (ii) any copies to be made of the Escrow Materials deposited
hereunder. Escrow Agent shall not open the sealed recepticals containing the
Escrow Materials, except upon receipt of mutual written instructions from PPTI
and FEMCARE.

     5.    RELEASE OF ESCROW MATERIALS.

     (a)   TO FEMCARE. Escrow Agent shall release and deliver any or all of the
Escrow Materials to FEMCARE upon the occurrence of any of the following events:

           (i)     Upon the written instructions of PPTI;

under any bankruptcy, insolvency, reorganization, liquidation, dissolution,
arrangement, composition, readjustment of debt or other similar act or law of
any jurisdiction, domestic or foreign, now or hereafter existing; (C) PPTI has
applied for a receiver, custodian or trustee of it or for all or a substantial
part of its property, made an assignment for the benefit of its creditors; (D)
written notice that a case, proceeding or other action has been commenced
against PPTI in bankruptcy, or seeking reorganization, liquidation, dissolution,
winding-up, arrangement, composition or readjustment of its debts, or any other

dissolution, arrangement, composition, readjustment of debt or other similar act
or law of any jurisdiction, domestic or foreign, now or hereafter existing; or
if a receiver, custodian or trustee of PPTI or for all or substantially all of
its properties shall be appointed; or if a warrant of attachment, execution or
distraint, or similar process, shall be issued against any substantial part of
the property of PPTI; and if in each such case in this clause (D) such condition
shall continue for a period of ninety (90) days undismissed, undischarged or
unbonded; (E) written notice along with reasonable evidence that shows that PPTI
has failed to deliver to FEMCARE at least *** of the quantities of Product
ordered on at least *** of acceptable purchase orders within the deliver periods
allowed in the Supply Agreement; or (F) written notice along with reasonable
evidence that shows that in two consecutive Marketing Years for which Minimum
Purchases are required under the Supply Agreement and in which FEMCARE has had
sales of Product equal to or in excess of the


- ------------------------
***  Material is confidential and has been omitted and filed separately with the
     Securities and Exchange Commission.

                                       3
<PAGE>

Minimum Purchases for such Marketing Years, PPTI has reduced FEMCARE's original
Annual Estimate (as defined in the Supply Agreement) by more than twenty percent
***.

           (iii)   Ten (10) business days after FEMCARE delivers to both Escrow
Agent and PPTI a letter or certificate signed by a director of FEMCARE
indicating that it is entitled to the Escrow Materials as a result of a material
breach by PPTI of the License Agreement (which breach was not cured in
accordance with the applicable provisions thereof).

     (b)   TO PPTI. Escrow Agent shall release and deliver all of the Escrow
Materials to PPTI within ten (10) business days after PPTI delivers to both
Escrow Agent and FEMCARE a letter or certificate signed by the President of PPTI
indicating that it is entitled to the Escrow Materials as a result of (1) a
breach by FEMCARE of the License Agreement (which breach was not cured in
accordance with the applicable provisions thereof) or (2) termination or
expiration of FEMCARE's license under Section 2.1 of the License Agreement.

     6.    LICENSE TO ESCROW MATERIALS. If the Escrow Materials are released and
delivered to FEMCARE, PPTI shall retain title to such Escrow Materials and
FEMCARE shall have a license to use such Escrow Materials in accordance with the
rights set out in the License Agreement.

     7.    TERMINATION OF ESCROW.

     (a)   The escrow shall terminate upon the earliest to occur of the
following events:

           (i)     mutual written agreement of the parties; or

           (ii)    delivery of a Process Description and related Sample and the
Toll Manufacturing Materials to FEMCARE or PPTI, as the case may be, in
accordance with the terms of Section 5.

     (b)   The parties agree that if the escrow is terminated pursuant to
Section 7(a)(i) above, the relevant Escrow Materials shall be delivered to
whichever party is designated in the written agreement among the parties.

     8.    ESCROW AGENT FEES. In consideration for performing its function as
escrow agent, Escrow Agent shall be paid solely by FEMCARE the charge for any
duties required in connection with this Escrow Agreement.

     9.    ESCROW AGENT.

     (a)   The obligations of the Escrow Agent are those specifically provided
in this Escrow Agreement, and the Escrow Agent shall have no liability under, or
duty to inquire into the terms and provisions of, any other agreement including,
without limitation, the License Agreement. The duties of the Escrow Agent are
purely ministerial in nature, and it shall not incur any liability whatsoever,
except for willful misconduct, gross negligence or breach of Article 9(d).

     Securities and Exchange Commission.

                                       4
<PAGE>

     (b)   The Escrow Agent shall not have any responsibility for the
genuineness or validity of any document or other item deposited with it or of
any signature thereon and shall not have any liability for acting in accordance
with any written instructions or certificates given to it hereunder and believed
by it to be signed by the proper parties. If the Escrow Agent shall receive
conflicting instructions, it shall advise FEMCARE and PPTI of such fact. FEMCARE
and PPTI shall have thirty (30) days to resolve the conflicting instructions and
jointly notify the Escrow Agent. If the Escrow Agent is not timely jointly
notified, it may at any time thereafter submit such conflict to arbitration in
accordance with the provisions of Section 10(c).

     (c)   The Escrow Agent may resign and be discharged from its duties
hereunder at any time by giving at least 30 days' notice of such resignation to
FEMCARE and PPTI, specifying a date upon which such resignation shall take
effect; provided, however, that the Escrow Agent shall continue to serve until
its successor accepts the appointment as new Escrow Agent. Upon receipt of such
notice, a successor escrow agent shall be appointed by FEMCARE and PPTI, such
successor escrow agent to become the Escrow Agent hereunder on the resignation
date specified in such notice. If an instrument of acceptance by a successor
escrow agent shall not have been delivered to the Escrow Agent within 40 days
after the giving of such notice of resignation, the resigning Escrow Agent may
at the expense of FEMCARE request that an arbitrator appoint a successor escrow
agent in accordance with the provisions of Section 10(c). FEMCARE and PPTI,
acting jointly, may at any time substitute a new escrow agent by giving 10 days'
notice thereof to the current Escrow Agent then acting and paying all expenses
of the current Escrow Agent.

     (d)   The Escrow Agent hereby agrees:

           i.      to maintain the Escrow Material and all information and/or
                   documentation coming into its possession or to its knowledge
                   under this Escrow Agreement in strictest confidence and
                   secrecy;

           ii.     not to make use of the Escrow Materials other than for the
                   performance of its obligations under this Escrow Agreement
                   and shall not disclose or release the same to any party other
                   than in accordance with the terms hereof; and

           iii.    that the obligations imposed hereunder shall continue,
                   notwithstanding release of the Escrow Materials or
                   termination of this Escrow Agreement, until or unless as the
                   Escrow Materials falls within the public domain, through no
                   fault of the Escrow Agent.

     (b)   SEVERABILITY. In the event that any provision of this Escrow
Agreement would be held in any jurisdiction to be invalid, prohibited or
unenforceable for any reason, such provision, as to such jurisdiction, shall be
ineffective, without invalidating the remaining provisions of this Escrow
Agreement or affecting the validity or enforceability of such provision in any
other jurisdiction. Notwithstanding the foregoing, if such provision could be
more narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without
invalidating the remaining provisions of this Escrow Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.

     (c)   GOVERNING LAW; DISPUTE RESOLUTION. Any controversy or claim arising
out of or relating to the Escrow Agreement, or the parties' decision to enter
into this Escrow Agreement, or the breach hereof, shall be settled by
arbitration in accordance with the International Arbitration Rules of the
American Arbitration Association ("AAA"), and judgment upon the award rendered
by the arbitrator may be entered in any court having jurisdiction thereof.
Notwithstanding the forgoing to the contrary or in the arbitration rules invoked
or in this Section 10 (c), the parties retain the right to request a judicial
authority to invoke interim measures of protection, and such request shall not
be deemed incompatible with this agreement to arbitrate or a waiver of the right
to arbitrate.

     The arbitration shall be held in the City of New York, State of New York,
U.S.A., and the arbitrator shall apply the substantive law of the State of
Delaware, except that the interpretation and enforcement of this arbitration
provision shall be governed by the Federal Arbitration Act. There shall be one
(1) arbitrator to be mutually agreed upon by the parties and to be selected from
the Regional Panel of Distinguished Neutrals. If the parties are unable to agree
upon such an arbitrator who is willing to serve within ten (10) days of receipt
of a demand to arbitrate by the other party, then the AAA shall appoint an
arbitrator willing to serve from the stated panel, or if no such panel exists,
the parties shall within three (3) days select one of the five (5) largest
international accounting firms (excluding those providing services for the
parties) and engage the managing partner or senior officer of its New York City
office to designate a partner of such firm to serve as the arbitrator. Failing
that, then the AAA shall appoint an arbitrator willing to serve from the
Regional Panel of Distinguished Neutrals, or if no such panel exists, then from
an appropriate AAA panel. It shall be the duty of the arbitrator to set dates
for preparation and hearing of any dispute and to expedite the resolution of
such dispute. Recognizing that the release of Escrow Materials is time critical,
the parties do hereby direct any arbitrator hereunder to reach a decision
regarding the release of Escrow Materials (which may be a temporary or
preliminary decision subject to such conditions as the arbitrator may, in its
sole discretion, order) within 30 days following his or her engagement or
appointment.

     It shall be the duty of the arbitrator to set dates for preparation and
hearing of any dispute and to expedite the resolution of such dispute. The
arbitrator shall permit and facilitate discovery, which will be conducted in
accordance with the Federal Rules of Civil Procedure, taking into account the
needs of the parties and the desirability of making discovery expeditious and
cost-effective. The arbitrator will set a discovery schedule with which the
parties will comply and attend depositions if requested by either party. The
arbitrator will entertain such presentation of sworn testimony or evidence,
written briefs and/or oral argument as the parties may wish to present; however,
no testimony or exhibits will be admissible unless the adverse party was
afforded an opportunity to

                                       7
<PAGE>

examine such witness and to inspect and copy such exhibits during the pre-
hearing discovery phase. The arbitrator shall among his other powers and
authorities, have the power and authority to award interim or preliminary
relief. The arbitrator shall not be empowered to award either party exemplary or
punitive damages or any enhanced damages for willful infringement and the
parties shall be deemed to have waived any right to such damages.

     A qualified court reporter will record and transcribe the proceedings.  The
decision of the arbitrator will be in writing and judgment upon the award by the
arbitrator may be entered into any court having jurisdiction thereof.  Prompt
handling and disposal of the issue is important.  Accordingly, the arbitrator is
instructed to assume adequate managerial initiative and control over discovery
and other aspects of the proceeding to schedule discovery and other activities
for substantially continuous work, thereby expediting the arbitration as much as
is deemed reasonable to him, but in all events to effect a final award within
365 days of the arbitrator's selection or appointment and within 20 days of the
close of evidence.

     The proceedings shall be confidential and the arbitrator shall issue
appropriate protective orders to safeguard both parties' confidential
information and the Escrow Materials.  The fees of the arbitrator and the AAA
shall be paid as designated by the arbitrator or, if he shall not so designate,
they shall be split equally between the parties.

     (d)   BINDING EFFECT; BENEFITS; ASSIGNMENT. This Escrow Agreement shall
enure to the benefit of and be binding upon the parties hereto and their
respective permitted successors and assigns. Nothing contained herein shall give
to any other person any benefit or any legal or equitable right, remedy or
claim. This Escrow Agreement shall not be assignable by PPTI without the prior
written consent of FEMCARE, which consent may be withheld in the sole discretion
of FEMCARE. Notwithstanding the foregoing, no consent of FEMCARE shall be
required if such assignment is in connection with the sale or transfer of all or
substantially all of the assets of PPTI or the merger or consolidation of PPTI
with or into any other business entity. FEMCARE shall be permitted to assign
this Escrow Agreement upon written notice to PPTI to any party to which it
assigns all of its rights under the License Agreement or sells or transfers all
or substantially all of its assets. No such assignment shall relieve the
assigning party of its underlying obligations under this Escrow Agreement.

     (e)   ENTIRE ESCROW AGREEMENT; AMENDMENTS. This Escrow Agreement and the
other writings referred to herein or delivered pursuant hereto which form a part
hereof contain the entire understanding of the parties with respect to its
subject matter. This Escrow Agreement may be amended only by a written
instrument duly executed by the parties hereto.

     (f)   WAIVERS. It is further understood and agreed that no failure or delay
by either party hereto in exercising any right, power or privilege under this
Escrow Agreement shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege hereunder.

     (g)   COUNTERPARTS. This Escrow Agreement may be executed in any number of
counterparts, and execution by each of the parties of any one of such
counterparts will constitute due

                                       8
<PAGE>

execution of this Escrow Agreement.  Each such counterpart hereof shall be
deemed to be an original instrument, and all such counterparts together shall
constitute but one agreement.

     (h)   HEADINGS. The article and section headings contained in this Escrow
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Escrow Agreement.

     IN WITNESS WHEREOF, the parties have caused this Escrow Agreement to be
signed by authorized persons, whereupon it became binding on the parties as of
the date first above written.

                              EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (this "Agreement") is entered into as of February
17, 2000 between PROTEIN POLYMER TECHNOLOGIES, INC., a Delaware corporation (the
"Company"), and J. THOMAS PARMETER (the "Employee").

                                     RECITAL

     The Company desires to continue to employ the Employee, and the Employee
desires to be so employed by the Company, on the terms and subject to the
conditions set forth in this Agreement. This Agreement supersedes that certain
employment agreement between the Company and the Employee dated November 1, 1996
(the "Prior Agreement").

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the premises and the mutual promises
set forth in this Agreement, the Company and the Employee hereby agree as
follows:

     1. Employment.

          (a) Subject to the terms and conditions contained herein, the Company
hereby agrees to employ the Employee, and the Employee accepts such employment,
from the date hereof until the earlier of (i) December 31, 2002 or (ii) the date
such employment is terminated pursuant to Section 4 of this Agreement. During
the Employee's employment under this Agreement, the Employee shall perform such
duties for the Company as may from time to time be assigned to the Employee by
Board of Directors of the Company (the "Board"). The Employee shall have the
title of Chairman of the Board of Directors, Chief Executive Officer and
President, or such other title or titles, if any, as from time to time may be
assigned to the Employee by the Board.

          (b) The Employee will devote his entire business time, energy,
attention and skill to the services of the Company and its affiliates and to the
promotion of their interests. So long as the Employee is employed by the
Company, the Employee shall not, without the written consent of the Company:

               (i) engage in any other activity for compensation, profit or
other pecuniary advantage, whether received during or after the term of this
Agreement;

               (ii) render or perform services of a business, professional, or
commercial nature other than to or for the Company, either alone or as an
employee, consultant, director, officer, or partner of another business entity,
whether or not for compensation, and whether or not such activity, occupation or
endeavor is similar to, competitive with, or adverse to the business or welfare
of the Company; or
<PAGE>

               (iii) invest in or become a shareholder of another corporation or
other entity; provided, that the Employee's investment solely as a shareholder
in another corporation shall not be prohibited hereby so long as such investment
is not in excess of one percent (1%) of any class of shares that are traded on a
national securities exchange.

          (c) Prior to or concurrently with the execution of this Agreement, the
Employee has executed an Employee Proprietary Information, Trade Secret and
Confidentiality Agreement (the "Confidentiality Agreement").

     2. Location of Employment. The Employee's principal place of employment
shall be at the executive offices of the Company located at 10655 Sorrento
Valley Road, San Diego, California 92121 or, as may be requested by the Board,
at any other office of the Company or any of its affiliates currently or
hereinafter located in San Diego County; provided, that at the direction of the
Board, the Employee may from time to time be required to travel to various
domestic and foreign locations.

     3. Compensation.

          (a) In exchange for full performance of the Employee's obligations and
duties under this Agreement, the Company shall pay the Employee an annual base
salary (the "Base Salary") equal to $212,000, payable in monthly installments in
accordance with the Company's standard payroll practices. In any month in which
the Employee shall be employed for less than the entire number of days in such
month, the compensation payable under this Section 3(a) shall be prorated on the
basis of the number of days during which the Employee was actually employed
divided by the number of days in such month.

          (b) The Base Salary is a gross amount, and the Company shall be
required to withhold from such amount deductions with respect to Federal, state
and local taxes, FICA, unemployment compensation taxes and similar taxes,
assessments or withholding requirements.

          (c) During the Employee's employment under this Agreement, the
Employee shall also be reimbursed by the Company for reasonable business
expenses actually incurred or paid by the Employee, consistent with the policies
established by the Board, in rendering to the Company the services provided for
in this Agreement, upon presentation of expense statements or such other
supporting information as is consistent with the policies of the Company.

          (d) The Employee shall be entitled to 20 business days vacation for
each full year of employment under this Agreement, which vacation time will
accrue in accordance with the vacation policy of the Company.

          (e) The Employee shall be entitled to participate in all benefit plans
(including deferred compensation plans and any medical, dental or life insurance
plans) which shall

                                       2
<PAGE>

be available from time to time to the domestic management employees of the
Company generally, except to the extent such participation in any plan would, in
the opinion of the Board, alter the intended tax treatment of such plan;
provided, however, that the Employee shall have no right under this Agreement to
participate in any stock option, stock purchase or other plan relating to shares
of capital stock of the Company or its affiliates. The Employee acknowledges and
agrees that the Board may in its discretion terminate at any time or modify from
time to time any such benefit plans.

          (f) During the term of this Agreement, the Company shall maintain, for
the benefit of the Employee, a "term life" insurance policy in the amount of
$250,000, the proceeds of which are payable to a person designated by the
Employee.

          (g) The Employee shall be entitled to use, at the expense of the
Company, a corporate automobile leased by the Company, provided that the monthly
lease payments shall be less than $550. Upon termination or expiration of this
Agreement, the Employee shall have the option to purchase such automobile from
the Company at a price equal to the book value thereof, as reflected on the most
recent regularly-prepared balance sheet of the Company. The Employee may
exercise this option by delivering a check, in the amount of such price, to the
Company within 30 days of such termination or expiration.

          (h) Other than as expressly set forth in this Section 3 or Sections
4(f) and 4(g) below, the Employee shall not receive any other compensation or
benefits except to the extent provided by the Board.

     4. Termination.

          (a) The employment of the Employee under this Agreement may be
terminated by the Company immediately upon giving the Employee notice if (i) the
Board determines that the Employee is unable to discharge his essential job
duties by reason of illness or injury or (ii) the Employee has been unable to
discharge his essential job duties by reason of illness or injury for either (A)
a period of two consecutive months or (B) twelve weeks in any twelve-month
period.

          (b) The employment of the Employee under this Agreement shall
terminate on the date of the Employee's death.


          (c) The employment of the Employee under this Agreement may be
terminated by the Company upon written notice from the Board that, in the
opinion of the Board, the Employee has (i) refused or failed (after reasonable
notice that such refusal or failure would result in termination of the
Employee's employment) to perform, to the satisfaction of the Board, any duties
assigned to the Employee by the Board, (ii) committed a breach of the terms of
this Agreement or any other legal obligation to the Company, (iii) failed to
perform any of the Employee's obligations under the Confidentiality Agreement,
(iv) demonstrated negligence or willful misconduct in the execution of the
Employee's assigned duties, (v) been convicted of or pleaded nolo
                                                             ----

<PAGE>

contendere to a felony or other serious crime, (vi) repeatedly and intemperately
- ----------
used alcohol or drugs, (vii) engaged in business practices which, in the opinion
of the Board, are unethical or reflect adversely on the Company, (viii)
misappropriated assets of the Company or (ix) been repeatedly absent from work
during normal business hours for reasons other than disability.

          (d) The employment of the Employee under this Agreement shall
terminate upon receipt by the Board of a written notice of resignation signed by
the Employee or, if no notice is given, on the date on which the Employee
voluntarily terminates his or her employment relationship with the Company.

          (e) In addition to the circumstances described in subsections (a),
(b), (c) and (d) above, the Company may terminate the Employee's employment for
any reason or no reason and with or without cause or prior notice. The Employee
understands that, subject to subsections (f)(iii) and (g) below, he is an
at-will employee and may be terminated by the Company without cause or prior
notice pursuant to this subsection (e) notwithstanding any other provision
contained in this Agreement. This at-will relationship will remain in effect
during the term of this Agreement and so long thereafter provided that the
Employee remains employed by the Company, unless such at-will employment
relationship is modified by a specific, express written agreement signed by the
Company.

          (f) If the Employee's employment is terminated pursuant to this
Section 4 or for any, other reason, the Employee shall not be entitled to any
compensation or benefits from the Company, under Section 3 of this Agreement or
otherwise, except for the following:

               (i) Base Salary and vacation pay accrued, and reasonable business
expenses incurred, under Section 3 of this Agreement through the date of such
termination;

               (ii) such benefits, if any, as may be required to be provided by
the Company under the Comprehensive Omnibus Budget Reconciliation Act (COBRA);

               and

               (iii) if the Employee's employment is terminated pursuant to
subsection (e) above, the Company shall continue to pay to the Employee the Base
Salary then in effect at intervals in accordance with the Company's standard
payroll practice until the termination date set forth in Section 1(a)(i) of this
Agreement.

          (g) Employee may terminate his employment hereunder for "Good Reason"
(as hereinafter defined)

                                       4
<PAGE>

               (i) For purposes of this Agreement, "Good Reason" shall mean a
termination of Employee's employment by Employee within 90 days after the
occurrence of any of the following after a "Change in Control" (as hereinafter
defined): (i) a reduction in Employee's Base Salary then in effect; (ii) a
material reduction in Employee's positions, duties and responsibilities from
those described in Section 1(a) of this Agreement; or (iii) the failure of the
Company to obtain the assumption of this Agreement by any successor to the
extent required pursuant to Section 10(a) of this Agreement.

               (ii) For purposes of this Agreement, the term "Change in Control"
shall mean the occurrence of any of the following events with respect to the
Company:

                    (A) All or substantially all of the assets of the Company
are sold or transferred to another corporation or entity; or

                    (B) The Company is sold, transferred, merged, consolidated,
ventured or reorganized into or with another corporation or entity, with the
result that upon conclusion of the transaction less than a majority of the
outstanding securities entitled to vote generally in the election of directors
or other capital interests of the acquiring corporation or entity are owned,
directly or indirectly, by the shareholders of the Company immediately prior to
the sale, transfer, merger, consolidation, venture or reorganization; or

                    (C) There is a report filed on Schedule 13D or Schedule
14D-1 (or any successor schedule, form or report), each as promulgated pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
disclosing that any person (as the term "person" is used in Section 13(d)(3) or
Section 14(d)(2) of the Exchange Act) has become the beneficial owner (as the
term "beneficial owner" is defined under Rule 13d-3 or any successor rule or
regulation promulgated under the Exchange Act) of securities representing more
than 50% of the combined voting power of the then-outstanding voting securities
of the Company; or

                    (D) The Company shall file a report or proxy statement
with the Securities and Exchange Commission pursuant to the Exchange Act
disclosing in response to Item 1 of Form 8-K thereunder or Item 14 of Schedule
14A thereunder (or any successor schedule, form or report or item therein) that
a change in control of the Company has or may have occurred or will or may occur
in the future pursuant to any then-existing contract or transaction; or

                    (E) The individuals who, at the beginning of any period of
two consecutive calendar years, constituted members of the Board cease for any
reason to constitute at least a majority thereof unless the nomination for
election by the Company's stockholders of each new director of the Company was
approved by a vote of at least two-thirds of the directors of the Company still
in office who were Directors of the Company at the beginning of any such period.

                                       5
<PAGE>

               (iii) Notwithstanding the foregoing, a termination shall not be
treated as a termination for Good Reason (i) if Employee shall have specifically
consented in writing to the occurrence of the event giving rise to the claim of
termination for Good Reason or (ii) unless Employee, within 30 days after
receiving written notice from the Company specifying in reasonable detail the
occurrence of one of such events, shall have delivered a written notice to the
Company stating that he intends to terminate his employment for Good Reason and
specifying the factual basis for such termination and such event, if capable of
being cured, shall not have been cured within 30 days of the receipt by the
Company of such notice.

               (iv) If Employee shall terminate his employment for Good Reason,
the Company shall pay Employee (or, in the event of his death, his devisee,
legatee or, if there is none, his estate) a lump-sum amount equal to the highest
level of Employee's annual Base Salary in effect on the date of the Change in
Control, multiplied by a factor of 2.99. Employee will also be entitled to any
vested benefits under any employee benefit plans.

     5. Employee's Representations.

          (a) The Employee represents that he has full authority to enter into
this Agreement and that he is free to enter into this Agreement and not under
any contractual restraint which would prohibit the Employee from satisfactorily
performing his duties to the Company under this Agreement.

          (b) The Employee hereby agrees to indemnify and hold harmless the
Company, its officers, directors and stockholders from and against any losses,
liabilities, damages or costs (including reasonable attorney's fees) arising out
of a breach, or claimed breach, of any of the representations, warranties and
covenants of the Employee set forth in this Agreement.

          (c) The Employee acknowledges that he is free to seek advice from
independent counsel with respect to this Agreement. The Employee has either
obtained such advice or, after carefully reviewing this Agreement, has decided
to forego such advice. The Employee is not relying on any representation or
advice from the Company or any of its officers, directors, attorneys or other
representatives regarding this Agreement, its content or effect.

     6. Arbitration. Any controversy or claim arising out of or relating to this
Agreement or any breach hereof or the Employee's employment by the Company or
termination thereof, shall be settled by arbitration by one arbitrator in
accordance with the rules of the American Arbitration Association, and judgment
upon such award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitration shall be held in the City of San Diego or
such other place as may be agreed upon at the time by the parties to the
arbitration.

                                       6
<PAGE>

     7. Equitable Relief. The Employee acknowledges that the Company is relying
for its protection upon the existence and validity of the provisions of this
Agreement, that the services to be rendered by the Employee are of a special,
unique and extraordinary character, and that irreparable injury will result to
the Company from any violation or continuing violation of the provisions of this
Agreement for which damages may not be an adequate remedy. Accordingly, the
Employee hereby agrees that in addition to the remedies available to the Company
by law or under this Agreement, the Company shall be entitled to obtain such
equitable relief as may be permitted by law in a court of competent jurisdiction
including, without limitation, injunctive relief from any violation or
continuing violation by the Employee of any term or provision of this Agreement.

     8. Governing Law. This Agreement shall be governed by and construed and
enforced in accordance with the internal substantive laws (and not the laws of
conflicts) of the State of California.

     9. Entire Agreement. This Agreement constitutes the whole agreement of the
parties hereto in reference to any employment of the Employee by the Company and
in reference to any of the matters or things herein provided for or hereinabove
discussed or mentioned in reference to such employment; all prior agreements,
promises, representations and understandings relative thereto (including,
without limitation, the Prior Agreement) being herein merged.

     10. Assignability.

          (a) In the event the Company shall merge or consolidate with any other
corporation, partnership or business entity, or all or substantially all of the
Company's business or assets shall be transferred in any manner to any other
corporation, partnership or business entity, then such successor to the Company
shall thereupon succeed to, and be subject to, all rights, interests, duties and
obligations of, and shall thereafter be deemed for all purposes hereof to be,
the "Company" under this Agreement. This Agreement shall inure to the benefit of
and be enforceable by Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If
Employee should die, any amounts payable to him hereunder shall be paid in
accordance with the terms of this Agreement to Employee's devisee, legatee, or
other designee or, if there be no such designee, to his estate.

          (b) This Agreement is personal in nature and the Employee shall not,
except as set forth in subsection (a) hereof, without the written consent of the
Company, assign or transfer this Agreement or any rights or obligations
hereunder.

          (c) Except as set forth in subsection (a) above, nothing expressed or
implied in this Agreement is intended or shall be construed to confer upon or
give to any person, other than the parties to this Agreement, any right, remedy
or claim under or by reason of this Agreement or of any term, covenant or
condition of this Agreement.

                                       7

     l1. Amendments; Waivers. This Agreement may be amended, modified,
superseded, canceled, renewed or extended and the terms or covenants of this
Agreement may be waived only by a written instrument executed by the parties to
this Agreement or, in the case of a waiver, by the party waiving compliance. Any
such written instrument must be approved by the Board to be effective as against
the Company. The failure of any party at any time or times to require
performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party of the breach
of any term or provision contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such breach, or a waiver of the breach of
any other term or covenant contained in this Agreement.

     12. Notice. All notices, requests or consents required or permitted under
this Agreement shall be made in writing and shall be given to the other parties
by personal delivery, overnight air courier (with receipt signature) or
facsimile transmission (with "answerback" confirmation of transmission), sent to
such parties' addresses or telecopy numbers as are set forth below such parties'
signatures to this Agreement, or such other addresses or telecopy numbers of
which the parties have given notice pursuant to this Section 12. Each such
notice, request or consent shall be deemed effective upon the date of actual
receipt, receipt signature or confirmation of transmission, as applicable.

      13. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     14. Survival. The representations and agreements of the Employee set forth
in Sections 5, 6 and 7 of this Agreement shall survive the expiration or
termination of this Agreement (irrespective of the reason for such expiration of
termination).

     15. Attorney's Fees. If any party to this Agreement seeks to enforce his or
its rights under this Agreement, the prevailing party or parties shall be
entitled to recover reasonable fees, costs and expenses incurred in connection
therewith including, without limitation, the fees, costs and expenses of
attorneys, accountants and experts, whether or not litigation is instituted, and

                              EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (this "Agreement") is entered into as of February
l7, 2000 between PROTEIN POLYMER TECHNOLOGIES, INC., a Delaware corporation
(the "Company"), and JOHN FLOWERS (the "Employee").

                                     RECITAL

     The Company desires to continue to employ the Employee, and the Employee
desires to be so employed by the Company, on the terms and subject to the
conditions set forth in this Agreement. This Agreement supersedes that certain
employment agreement between the Company and the Employee dated November 1, 1996
(the "Prior Agreement").

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the premises and the mutual promises
set forth in this Agreement, the Company and the Employee hereby agree as
follows:

     1.   Employment.

          (a) Subject to the terms and conditions contained herein, the Company
hereby agrees to employ the Employee, and the Employee accepts such employment,
from the date hereof until the earlier of (i) December 31, 2002 or (ii) the date
such employment is terminated pursuant to Section 4 of this Agreement. During
the Employee's employment under this Agreement, the Employee shall perform such
duties for the Company as may from time to time be assigned to the Employee by
Board of Directors of the Company (the "Board") or the President of the Company
(the "Designated Officer"). The Employee shall have the title of Vice President,
Planning and Operations and Director, Intellectual Property, or such other title
or titles, if any, as from time to time may be assigned to the Employee by the
Board.

          (b) The Employee will devote his entire business time, energy,
attention and skill to the services of the Company and its affiliates and to the
promotion of their interests. So long as the Employee is employed by the
Company, the Employee shall not, without the written consent of the Company:

                  (i) engage in any other activity for compensation, profit or
other pecuniary advantage, whether received during or after the term of this
Agreement;

                  (ii) render or perform services of a business, professional,
or commercial nature other than to or for the Company, either alone or as an
employee, consultant, director, officer, or partner of another business entity,
whether or not for compensation, and whether or not such activity, occupation or
endeavor is similar to, competitive with, or adverse to the business or welfare
of the Company; or
<PAGE>

                  (iii) invest in or become a shareholder of another corporation
or other entity; provided, that the Employee's investment solely as a
shareholder in another corporation shall not be prohibited hereby so long as
such investment is not in excess of one percent (1%) of any class of shares that
are traded on a national securities exchange.

          (c) Prior to or concurrently with the execution of this Agreement, the
Employee has executed an Employee Proprietary information, Trade Secret and
Confidentiality Agreement (the "Confidentiality Agreement").

     2. Location of Employment. The Employee's principal place of employment
shall be at the executive offices of the Company located at 10655 Sorrento
Valley Road, San Diego, California 92121 or, as may be requested by the Board,
at any other office of the Company or any of its affiliates currently or
hereinafter located in San Diego County; provided, that at the direction of the
Board or the Designated Officer, the Employee may from time to time be required
to travel to various domestic and foreign locations.

     3. Compensation.

          (a) In exchange for full performance of the Employee's obligations and
duties under this Agreement, the Company shall pay the Employee an annual base
salary (the "Base Salary") equal to $125,000, payable in monthly installments in
accordance with the Company's standard payroll practices. In any month in which
the Employee shall be employed for less than the entire number of days in such
month, the compensation payable under this Section 3(a) shall be prorated on the
basis of the number of days during which the Employee was actually employed
divided by the number of days in such month.

          (b) The Base Salary is a gross amount, and the Company shall be
required to withhold from such amount deductions with respect to Federal, state
and local taxes, FICA, unemployment compensation taxes and similar taxes,
assessments or withholding requirements.

          (c) During the Employee's employment under this Agreement, the
Employee shall also be reimbursed by the Company for reasonable business
expenses actually incurred or paid by the Employee, consistent with the policies
established by the Board, in rendering to the Company the services provided for
in this Agreement, upon presentation of expense statements or such other
supporting information as is consistent with the policies of the Company.

          (d) The Employee shall be entitled to 20 business days vacation for
each full year of employment under this Agreement, which vacation time will
accrue in accordance with the vacation policy of the Company.

          (e) The Employee shall be entitled to participate in all benefit plans
(including deferred compensation plans and any medical, dental or life insurance
plans) which shall

                                       2
<PAGE>

be available from time to time to the domestic management employees of the
Company generally, except to the extent such participation in any plan would, in
the opinion of the Designated Officer, alter the intended tax treatment of such
plan; provided, however, that the Employee shall have no right under this
Agreement to participate in any stock option, stock purchase or other plan
relating to shares of capital stock of the Company or its affiliates. The
Employee acknowledges and agrees that the Board may in its discretion terminate
at any time or modify from time to time any such benefit plans.

          (f) Other than as expressly set forth in this Section 3 or
Sections 4(f) and 4(g) below, the Employee shall not receive any other
compensation or benefits except to the extent provided by the Board.

     4. Termination.

          (a) The employment of the Employee under this Agreement may be
terminated by the Company immediately upon giving the Employee notice if (i) the
Board determines that the Employee is unable to discharge his essential job
duties by reason of illness or injury or (ii) the Employee has been unable to
discharge his essential job duties by reason of illness or injury for either (A)
a period of two consecutive months or (B) twelve weeks in any twelve-month
period.

          (b) The employment of the Employee under this Agreement shall
terminate on the date of the Employee's death.

          (c) The employment of the Employee under this Agreement may be
terminated by the Company upon written notice from the Board that, in the
opinion of the Board, the Employee has (i) refused or failed (after reasonable
notice that such refusal or failure would result in termination of the
Employee's employment) to perform, to the satisfaction of the Designated Officer
or the Board, any duties assigned to the Employee by the Designated Officer or
the Board, (ii) committed a breach of the terms of this Agreement or any other
legal obligation to the Company, (iii) failed to perform any of the Employee's
obligations under the Confidentiality Agreement, (iv) demonstrated negligence or
willful misconduct in the execution of the Employee's assigned duties, (v) been
convicted of or pleaded nolo contendere to a felony or other serious crime, (vi)
                        ---- ----------
repeatedly and intemperately used alcohol or drugs, (vii) engaged in business
practices which, in the opinion of the Board, are unethical or reflect adversely
on the Company, (viii) misappropriated assets of the Company or (ix) been
repeatedly absent from work during normal business hours for reasons other than
disability.

          (d) The employment of the Employee under this Agreement shall
terminate upon receipt by the Board of a written notice of resignation signed by
the Employee or, if no notice is given, on the date on which the Employee
voluntarily terminates his or her employment relationship with the Company.

                                       3
<PAGE>

          (e) In addition to the circumstances described in subsections (a),
(b), (c) and (d) above, the Company may terminate the Employee's employment for
any reason or no reason and with or without cause or prior notice. The Employee
understands that, subject to subsections (f)(iii) and (g) below, he is an
at-will employee and may be terminated by the Company without cause or prior
notice pursuant to this subsection (e) notwithstanding any other provision
contained in this Agreement. This at-will relationship will remain in effect
during the term of this Agreement and so long thereafter provided that the
Employee remains employed by the Company, unless such at-will employment
relationship is modified by a specific, express written agreement signed by the
Company.

          (f) If the Employee's employment is terminated pursuant to this
Section 4 or for any other reason, the Employee shall not be entitled to any
compensation or benefits from the Company, under Section 3 of this Agreement or
otherwise, except for the following:

                  (i) Base Salary and vacation pay accrued, and reasonable
business expenses incurred, under Section 3 of this Agreement through the date
of such termination;

                  (ii) such benefits, if any, as may be required to be provided
by the Company under the Comprehensive Omnibus Budget Reconciliation Act
(COBRA);

                  and

                  (iii) if the Employee's employment is terminated pursuant to
subsection (e) above, the Company shall continue to pay to the Employee the Base
Salary then in effect at intervals in accordance with the Company's standard
payroll practice until the earlier of (A) six months following such termination
or (B) the termination date set forth in Section l(a)(i) of this Agreement.

          (g) Employee may terminate his employment hereunder for "Good Reason"
(as hereinafter defined).

                  (i) For purposes of this Agreement, "Good Reason" shall mean a
termination of Employee's employment by Employee within 90 days after the
occurrence of any of the following after a "Change in Control" (as hereinafter
defined): (i) a reduction in Employee's Base Salary then in effect; (ii) a
material reduction in Employee's positions, duties and responsibilities from
those described in Section l(a) of this Agreement; or (iii) the failure of the
Company to obtain the assumption of this Agreement by any successor to the
extent required pursuant to Section 10(a) of this Agreement.

                  (ii) For purposes of this Agreement, the term "Change in
Control" shall mean the occurrence of any of the following events with respect
to the Company:

<PAGE>

                         (A) All or substantially all of the assets of the
Company are sold or transferred to another corporation or entity; or

                         (B) The Company is sold, transferred, merged,
consolidated, ventured or reorganized into or with another corporation or
entity, with the result that upon conclusion of the transaction less than a
majority of the outstanding securities entitled to vote generally in the
election of directors or other capital interests of the acquiring corporation or
entity are owned, directly or indirectly, by the shareholders of the Company
immediately prior to the sale, transfer, merger, consolidation, venture or
reorganization; or

                         (C) There is a report filed on Schedule 13D or Schedule
14D-1 (or any successor schedule, form or report), each as promulgated pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
disclosing that any person (as the term "person" is used in Section 13(d)(3) or
Section 14(d)(2) of the Exchange Act) has become the beneficial owner (as the
term "beneficial owner" is defined under Rule 13d-3 or any successor rule or
regulation promulgated under the Exchange Act) of securities representing more
than 50% of the combined voting power of the then-outstanding voting securities
of the Company; or

                         (D) The Company shall file a report or proxy statement
with the Securities and Exchange Commission pursuant to the Exchange Act
disclosing in response to Item 1 of Form 8-K thereunder or Item 14 of Schedule
14A thereunder (or any successor schedule, form or report or item therein) that
a change in control of the Company has or may have occurred or will or may occur
in the future pursuant to any then-existing contract or transaction; or

                         (E) The individuals who, at the beginning of any period
of two consecutive calendar years, constituted members of the Board cease for
any reason to constitute at least a majority thereof unless the nomination for
election by the Company's stockholders of each new director of the Company was
approved by a vote of at least two-thirds of the directors of the Company still
in office who were Directors of the Company at the beginning of any such period.

                  (iii) Notwithstanding the foregoing, a termination shall not
be treated as a termination for Good Reason (i) if Employee shall have
specifically consented in writing to the occurrence of the event giving rise to
the claim of termination for Good Reason or (ii) unless Employee, within 30 days
after receiving written notice from the Company specifying in reasonable detail
the occurrence of one of such events, shall have delivered a written notice to
the Company stating that he intends to terminate his employment for Good Reason
and specifying the factual basis for such termination and such event, if capable
of being cured, shall not have been cured within 30 days of the receipt by the
Company of such notice.

                  (iv) If Employee shall terminate his employment for Good
Reason, the Company shall pay Employee (or, in the event of his death, his
devisee, legatee or, if there is none, his estate) a lump-sum amount equal to
the highest level of Employee's annual Base Salary in effect on the date of the
Change in Control, multiplied by a factor of 2.0. Employee will also be entitled
to any vested benefits under any employee benefit plans.

     5. Employee's Representations.

          (a) The Employee represents that he has full authority to enter into
this Agreement and that he is free to enter into this Agreement and not under
any contractual restraint which would prohibit the Employee from satisfactorily
performing his duties to the Company under this Agreement.

          (b) The Employee hereby agrees to indemnify, and hold harmless the
Company, its officers, directors and stockholders from and against any losses,
liabilities, damages or costs (including reasonable attorney's fees) arising out
of a breach, or claimed breach, of any of the representations, warranties and
covenants of the Employee set forth in this Agreement.

          (c) The Employee acknowledges that he is free to seek advice from
independent counsel with respect to this Agreement. The Employee has either
obtained such advice or, after carefully reviewing this Agreement, has decided
to forego such advice. The Employee is not relying on any representation or
advice from the Company or any of its officers, directors, attorneys or other
representatives regarding this Agreement, its content or effect.

     6. Arbitration. Any controversy or claim arising out of or relating to this
Agreement or any breach hereof or the Employee's employment by the Company or
termination thereof, shall be settled by arbitration by one arbitrator in
accordance with the rules of the American Arbitration Association, and judgment
upon such award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitration shall be held in the City of San Diego or
such other place as may be agreed upon at the time by the parties to the
arbitration.

     7. Equitable Relief. The Employee acknowledges that the Company is relying
for its protection upon the existence and validity of the provisions of this
Agreement, that the services to be rendered by the Employee are of a special,
unique and extraordinary character, and that irreparable injury will result to
the Company from any violation or continuing violation of the provisions of this
Agreement for which damages may not be an adequate remedy. Accordingly, the
Employee hereby agrees that in addition to the remedies available to the Company
by law or under this Agreement, the Company shall be entitled to obtain such
equitable relief as may be permitted by law in a court of competent jurisdiction
including, without limitation, injunctive relief from any violation or
continuing violation by the Employee of any term or provision of this Agreement.

                                       6
<PAGE>

     8. Governing Law. This Agreement shall be governed by and construed and
enforced in accordance with the internal substantive laws (and not the laws of
conflicts) of the State of California.

     9. Entire Agreement. This Agreement constitutes the whole agreement of the
parties hereto in reference to any employment of the Employee by the Company and
in reference to any of the matters or things herein provided for or hereinabove
discussed or mentioned in reference to such employment; all prior agreements,
promises, representations and understandings relative thereto (including,
without limitation, the Prior Agreement) being herein merged.

     10. Assignability.

          (a) In the event the Company shall merge or consolidate with any
other corporation, partnership or business entity, or all or substantially all
of the Company's business or assets shall be transferred in any manner to any
other corporation, partnership or business entity, then such successor to the
Company shall thereupon succeed to, and be subject to, all rights, interests,
duties and obligations of, and shall thereafter be deemed for all purposes
hereof to be, the "Company" under this Agreement. This Agreement shall inure to
the benefit of and be enforceable by Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If Employee should die, any amounts payable to him
hereunder shall be paid in accordance with the terms of this Agreement to
Employee's devisee, legatee, or other designee or, if there be no such designee,
to his estate.

          (b) This Agreement is personal in nature and the Employee shall not,
except as set forth in subsection (a) hereof, without the written consent of the
Company, assign or transfer this Agreement or any rights or obligations
hereunder

          (c) Except as set forth in subsection (a) above, nothing expressed or
implied in this Agreement is intended or shall be construed to confer upon or
give to any person, other than the parties to this Agreement, any right, remedy
or claim under or by reason of this Agreement or of any term, covenant or
condition of this Agreement.

     11. Amendments; Waivers. This Agreement may be amended, modified,
superseded, canceled, renewed or extended and the terms or covenants of this
Agreement may be waived only by a written instrument executed by the parties to
this Agreement or, in the case of a waiver, by the party waiving compliance. Any
such written instrument must be approved by the Board to be effective as against
the Company. The failure of any party at any time or times to require
performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party of the breach
of any term or provision contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such breach, or a waiver of the breach of
any other term or covenant contained in this Agreement.

                                       7

such parties' addresses or telecopy numbers as are set forth below such parties'
signatures to this Agreement, or such other addresses or telecopy numbers of

notice, request or consent shall be deemed effective upon the date of actual
receipt, receipt signature or confirmation of transmission, as applicable.

     13. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction

     14. Survival. The representations and agreements of the Employee set forth
in Sections 5, 6 and 7 of this Agreement shall survive the expiration or
termination of this Agreement (irrespective of the reason for such expiration of
termination).

its rights under this Agreement, the prevailing party or parties shall be
entitled to recover reasonable fees, costs and expenses incurred in connection
therewith including, without limitation, the fees, costs and expenses of
attorneys, accountants and experts, whether or not litigation is instituted, and
including such fees, costs and expenses of appeals.

the opinion of the Designated Officer, alter the intended tax treatment of such
plan; provided, however, that the Employee shall have no right under this
Agreement to participate in any stock option, stock purchase or other plan

          (g) Employee may terminate his employment hereunder for "Good Reason"

                    (B) The Company is sold, transferred, merged, consolidated,
ventured or reorganized into or with another corporation or entity, with the
result that upon conclusion of the transaction less than a majority of the
outstanding securities entitled to vote generally in the election of directors
or other capital interests of the acquiring corporation or entity are owned,
directly or indirectly, by the shareholders of the Company immediately prior to
the sale, transfer, merger, consolidation, venture or reorganization; or

                    (C) There is a report filed on Schedule 13D or Schedule
14D-1 (or any successor schedule, form or report), each as promulgated pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
disclosing that any person (as the term "person" is used in Section 13(d)(3) or
Section 14(d)(2) of the Exchange Act) has become the beneficial owner (as the
term "beneficial owner" is defined under Rule 13d-3 or any successor rule or
regulation promulgated under the Exchange Act) of securities representing more
than 50% of the combined voting power of the then-outstanding voting securities
of the Company; or

                    (D) The Company shall file a report or proxy statement with
the Securities and Exchange Commission pursuant to the Exchange Act disclosing

in the future pursuant to any then-existing contract or transaction; or

                    (E) The individuals who, at the beginning of any period of
two consecutive calendar years, constituted members of the Board cease for any
reason to constitute at least a majority thereof unless the nomination for
election by the Company's stockholders of each new director of the Company was
approved by a vote of at least two-thirds of the directors of the Company still
in office who were Directors of the Company at the beginning of any such period.

               (iii) Notwithstanding the foregoing, a termination shall not be
treated as a termination for Good Reason (i) if Employee shall have specifically
consented in writing to the occurrence of the event giving rise to the claim of
termination for Good Reason or (ii) unless Employee, within 30 days after
receiving written notice from the Company specifying in reasonable detail the
occurrence of one of such events, shall have delivered a written notice to the
Company stating that he intends to terminate his employment for Good Reason and
specifying the factual basis for such termination and such event, if capable of
being cured, shall not have been cured within 30 days of the receipt by the
Company of such notice.
<PAGE>

               (iv) If Employee shall terminate his employment for Good Reason,
the Company shall pay Employee (or, in the event of his death, his devisee,
legatee or, if there is none, his estate) a lump-sum amount equal to the highest
level of Employee's annual Base Salary in effect on the date of the Change in
Control, multiplied by a factor of 2.0. Employee will also be entitled to any
vested benefits under any employee benefit plans.

     5. Employee's Representations.

          (a) The Employee represents that he has full authority to enter into

Company, its officers, directors and stockholders from and against any losses,
liabilities, damages or costs (including reasonable attorney's fees) arising out

covenants of the Employee set forth in this Agreement.

          (c) The Employee acknowledges that he is free to seek advice from

to forego such advice. The Employee is not relying on any representation or
advice from the Company or any of its officers, directors, attorneys or other
representatives regarding this Agreement, its content or effect.

     6. Arbitration. Any controversy or claim arising out of or relating to this
Agreement or any breach hereof or the Employee's employment by the Company or
termination thereof, shall be settled by arbitration by one arbitrator in
accordance with the rules of the American Arbitration Association, and judgment
upon such award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitration shall be held in the City of San Diego or
such other place as may be agreed upon at the time by the parties to the
arbitration.

     7. Equitable Relief. The Employee acknowledges that the Company is relying
for its protection upon the existence and validity of the provisions of this
Agreement, that the services to be rendered by the Employee are of a special,
unique and extraordinary character, and that irreparable injury will result to
the Company from any violation or continuing violation of the provisions of this
Agreement for which damages may not be an adequate remedy. Accordingly, the
Employee hereby agrees that in addition to the remedies available to the Company
by law or under this Agreement, the Company shall be entitled to obtain such
equitable relief as may be permitted by law in a court of competent jurisdiction
including, without limitation, injunctive relief from any violation or
continuing violation by the Employee of any term or provision of this Agreement.

parties hereto in reference to any employment of the Employee by the Company and
in reference to any of the matters or things herein provided for or hereinabove

corporation, partnership or business entity, or all or substantially all of the
Company's business or assets shall be transferred in any manner to any other
corporation, partnership or business entity, then such successor to the Company
shall thereupon succeed to, and be subject to, all rights, interests, duties and
obligations of, and shall thereafter be deemed for all purposes hereof to be,
the "Company" under this Agreement. This Agreement shall inure to the benefit of
and be enforceable by Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If
Employee should die, any amounts payable to him hereunder shall be paid in
accordance with the terms of this Agreement to Employee's devisee, legatee, or
other designee or, if there be no such designee, to his estate.

Company, assign or transfer this Agreement or any rights or obligations
hereunder.

          (c) Except as set forth in subsection (a) above, nothing expressed or

give to any person, other than the parties to this Agreement, any right, remedy
or claim under or by reason of this Agreement or of any term, covenant or
condition of this Agreement.

     11. Amendments; Waivers. This Agreement may be amended, modified,
superseded, canceled, renewed or extended and the terms or covenants of this
Agreement may be waived only by a written instrument executed by the parties to
this Agreement or, in the case of a waiver, by the party waiving compliance. Any
such written instrument must be approved by the Board to be effective as against

performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party, of the
breach of any term or provision contained in this Agreement, whether by conduct
or otherwise, in any one or more instances, shall be deemed to be, or construed
as, a further or continuing waiver of any such breach, or a waiver of the breach
of any other term or covenant contained in this Agreement.

disclosing that any person (as the term "person" is used in Section 13(d)(3) or
Section 14(d)(2) of the Exchange Act) has become the beneficial owner (as the

receiving written notice from the Company specifying in reasonable detail the
occurrence of one of such events, shall have delivered a written notice to the

corporation, partnership or business entity, or all or substantially all of the
Company's business or assets shall be transferred in any manner to any other
corporation, partnership or business entity, then such successor to the Company
shall thereupon succeed to, and be subject to, all rights, interests, duties and
obligations of, and shall thereafter be deemed for all purposes hereof to be,
the "Company" under this Agreement. This Agreement shall inure to the benefit of
and be enforceable by Employee's personal or legal representatives, executors,

performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party of the breach
of any term or provision contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such breach, or a waiver of the breach of
any other term or covenant contained in this Agreement.
