ITEM 1--BUSINESS

OVERVIEW

Senetek PLC ("Senetek") is a science-driven biotechnology company that develops,
manufactures and markets proprietary products for the enhancement of quality of
life, primarily products for the diagnosis and treatment of aging-related
healthcare problems. Recently, the company has decided to focus on two business
sectors, biopharmaceuticals, in particular therapeutic agents for erectile
dysfunction and female sexual dysfunction, and proprietary skincare
technologies. In connection with product development activities, we sponsor
research in the life sciences and biotechnology fields.

Senetek PLC is a public limited company that was registered in England in 1983
(registration number 1759068). We have two wholly owned subsidiaries, Senetek
Drug Delivery Technologies Inc. and Carme Cosmeceutical Sciences Inc., both of
which are Delaware corporations.

PRODUCT RESEARCH AND DEVELOPMENT

Biopharmaceuticals

Invicorp(TM) - We estimate that 100 million men worldwide suffer from some form
of erectile dysfunction. Our Invicorp(TM) product employs an easy to use
self-administered automatic delivery system to deliver a combination therapy of
two specific drugs, vasoactive intestinal polypeptide and phentolamine mesylate,
for the treatment of erectile dysfunction. Phase III clinical trials for
Invicorp(TM) are now complete. In clinical trials, more than 80% of patients
responded successfully to treatment with Invicorp(TM). Of these patients, 60%
had withdrawn from previous treatment with alternative erectile dysfunction
therapies. Invicorp(TM) was approved for marketing in Denmark in July 1998. In
December 1998 we received news from the Medicines Evaluation Agency in Ireland
that Invicorp(TM) received clearance on safety and efficacy and we are now
waiting final approval. In March 1999, the United Kingdom's Committee on Safety
of Medicines informed us that it was prepared to advise the United Kingdom's
licensing authority to grant a marketing authorization for Invicorp(TM) upon our
compliance with specified conditions. On January 31,2000 we filed an amendment
that addressed all the conditions cited by the United Kingdom Medicines Control
Agency ( MCA ). During May 1999 we were notified by New Zealand s Medicines
Assessment Advisory Committee that they had recommended Invicorp(TM) be approved
for the treatment of erectile dysfunction. We are awaiting approval of marketing
authorization applications for Invicorp(TM) in the Republic of Ireland,
Switzerland and South Africa. Invicorp(TM) has received Investigational New Drug
approval from the United States Federal Food and Drug Administration ( FDA ). An
application for European wide Marketing Authorization Approvals under the
European Mutual Recognition Procedure has been initiated selecting Denmark as
the Reference Member State.

                                       3
<PAGE>

In August 1999, Senetek announced that it had received word from the MCA and the
FDA that a competitor's safety trial on phentolamine mesylate revealed
pre-clinical tumors (proliferation of brown fat cells in mice) and as a result
have placed a clinical hold on new studies with products containing
phentolamine. These findings are preliminary. Soteros Limited, an expert
pharmacotoxicologist firm, has completed a comprehensive review of Senetek's
clinical data and the medical literature and has concluded that there is no
relevancy in humans. The FDA definition of tumor is very broad and encompasses
any growth, inflammatory or non-inflammatory, benign or malignant and includes
proliferation of brown fat cells. The competitor's product differs significantly
from our product in concentration, route of delivery and chemistry. It is
noteworthy to mention that in Spain, Holland and some other European Union
("EU") countries, a product containing phentolamine mesylate has been recently
approved for use in Erectile Dysfunction.

During the first quarter 2000, we entered into an alliance with Owen Mumford
Limited to supply their Autoject(R) Mini exclusive to Erectile Dysfunction for
the automatic delivery of Invicorp(TM). The Autoject(R) Mini is a cost effective
therapeutic delivery system that is esthetically appealing, utilizing an ultra
fine needle. The Autoject(R) Mini offers proven manufactureability and universal
contract manufacturing capabilities,thus resolving outstanding production
issues. Stability studies are currently being scheduled and will be done
concurrently with other regulatory requirements. We have also made arrangements
with Akorn, Inc. to do the filling of the Autoinject(R) Mini. The timeline to
market for Invicorp(TM) is dependent on several factors, not the least of which
is the phentolamine mesylate issue. We remain positive and are working
diligently towards completing the necessary steps to gain regulatory and
marketing approval. Review of alternative drug delivery systems are also
underway to include needleless autoinjectors and topical administration.

Adrenaject(TM) Adrenaject(TM) uses an automatic injector syringe to deliver a
self-injectable formulation of epinephrine, an emergency antidote for
anaphylactic shock. Anaphylactic shock is a life threatening condition triggered
by a severe allergic reaction to insect stings, insect bites and certain foods.
In 1998, we filed an Abbreviated New Drug Application ( ANDA ) with the FDA for
the Adrenaject(TM). In October 1998, we entered into an agreement with ICN
Pharmaceuticals Inc. in which we granted to ICN the worldwide rights to market
and sell Adrenaject(TM) upon receipt of necessary regulatory approvals. Pursuant
to the agreement, ICN has committed to purchase an initial quantity of
Adrenaject(TM) valued at $1.5 million and will pay licensing fees of up to $3
million upon achievement of certain milestones. We have developed a pediatric
formulation of epinephrine. On January 14, 1999, we received notification from
the FDA that our ANDA was found to have several deficiencies. We are currently
in the process of addressing these deficiencies and exploring alternatives to
get to market quickly.

Other Products

Monoclonal Antibodies - We market monoclonal antibodies to the scientific
community for research on Alzheimer's disease under an exclusive agreement with
the Research Foundation for Mental Hygiene. Our customers include Glaxo, Pfizer,
Wyeth Ayerst, Amgen, Pharmacia UpJohn, Eli Lilly and Genentech. As Monoclonal
Antibodies are not a core business, we are currently seeking partners for market
alliances for this business unit.

Reliaject(TM) - Our Reliaject(TM) disposable autoinjector offers advantages that
cannot be gained through the use of pre-filled syringes or re-loadable
autoinjectors. We continue to work towards finalizing the development of
Reliaject(TM) for epinephrine and other products. Products that are currently
being considered include migraine treatment drugs, infertility treatment
regimens, human growth hormones and new analgesic pain therapies. The cost of
continued development is estimated to be $500,000.

Skincare

Cytokinins - Senetek has five patents on two natural growth factors, Kinetin and
Zeatin.

                                       4
<PAGE>

Kinetin - Kinetin (N6-furfuryladenine) retards aging of plants and delays
age-related changes in cultured human skin cells. In clinical studies conducted
over the past two years at the University of California, Irvine, Kinetin showed
a good-to-excellent response in the majority of patients in partially reversing
the clinical signs of photodamaged skin and in restoring normal skin barrier
function. In contrast to other anti-aging products such as retinoids and
alpha-hydroxy acids, Kinetin did not produce any clinical signs or symptoms of
irritation. We are currently continuing development of new products as work is
being performed on Kinetin Plus products at The University of Aarhus in Denmark
and we have made arrangements with The University of Irvine, Department of
Dermatology, to further study Kinetin and initiate work on Zeatin, the basis of
which will be transformed to a multi-year research collaboration.

In July 1998, we granted to Osmotics Corporation an exclusive license to market
Kinetin to the high-end prestige market (department stores). On January 21,
2000, we notified Osmotics that they are in breach of contract for non-payment
of royalties and selling in unauthorized channels of distribution. Currently,
the agreement is before the American Arbitration Association for resolution. In
October 1998, we granted to ICN Pharmaceuticals Inc. ("ICN") an exclusive
worldwide license to market Kinetin to the ethical skin care market, which
includes dermatologists and cosmetic surgeons. The ICN license agreement
includes a manufacturing supply agreement and royalty income on net sales. ICN
has launched Kinerase(R) in USA, Canada and Argentina and expects to expand to
several other European and Latin American countries in fiscal 2000.

On December 15, 1999 we entered into a license and supply agreement with Obaji
Medical Products Inc., ("OMP") for the exclusive marketing and distribution of
Kinetin in the mass market channel of distribution for China, Hong Kong, Japan,
Singapore, Korea and other designated Asian countries. In addition, OMP receives
exclusivity for Kinetin in the multi-level marketing channel of distribution for
Taiwan. For the grant of the distribution rights the agreement provides for
payments to Senetek of a $1,150,000 license fee, $450,000 of which was received
in 1999 with the remainder to be received in 2000. Market launches are
anticipated in the second half of 2000 on completion of the product registration
requirements in the various countries.

On March 14, 2000, OMP entered into a joint venture to market Kinetin products
with Rohto Pharmaceuticals Co., Ltd., Osaka, Japan, founded in 1899 and listed
on the Tokyo and Osaka stock exchanges since 1964. The distribution structure in
Japan will bring us access to the largest cosmetics market in Asia. We believe
this license will contribute substantially to the overall success of Kinetin
world wide not only financially but also in terms of international recognition
of Kinetin as a key technology in skin care.

Zeatin - We hold patents for anti-aging on a promising new Cytokinin, Zeatin.
During 1999 we worked on a development plan for Zeatin. Zeatin is an analogue of
Kinetin with preliminary in vitro data suggesting that it is more active than
Kinetin at higher concentrations. A development program has been established to
study the safety and efficacy of Zeatin for both photo-damaged skin and
psoriasis.

Other Products

Our other products are designed to meet specific niche segments of the market.
These include Mill Creek(R), Sleepy Hollow Botanicals and Biotene H-24. We also
have two specialty mass market lines: Silver Fox(R), a product for gray hair,
and Allercreme(R), a hypoallergenic range of skincare products for sensitive
skin, developed in conjunction with dermatologists.

In May 1999, exclusive rights for the worldwide distribution of Mill Creek(R)
and Silver Fox(R) products were granted to the United States International
Trading Corporation (the "USITC"). At this time CCSI also sold its inventories
of Mill Creek(R) and Silver Fox(R) products to USITC for $348,000. For the grant
of the distribution rights CCSI received an initial $100,000 license fee. The
agreement provides for minimum quarterly royalty payments based on net sales of
the products. The agreement calls for an option where USITC can purchase these
product lines for $2.8 million.

                                       5
<PAGE>

In May 1999, the contract with Quimlam, Inc., (d.b.a. Omega Distributing), was
extended through May 2000. Omega Distributing has the exclusive right to
distribute Allercreme(R) throughout the United States.

Research and Development

We sponsor research in the life sciences and biotechnology fields, with
particular emphasis on research relating to the diagnosis and treatment of
healthcare problems related to aging. We develop and market biopharmaceutical
and skincare products based upon the results of this research.

A significant proportion of our historic and current operating expenses have
related to our clinical research agreements with consultants, clinicians and
research scientists. Under these agreements, we fund agreed-upon programs of the
consultants', clinicians' or research scientists' work and retain exclusive
rights to manufacture and market worldwide any products arising from this
research. Currently, none of our products has reached the marketing stage except
for our Mill Creek line of products, products incorporating Kinetin (sold by
Osmotics corporation, ICN Pharmaceuticals Inc. and OMP under license agreements
with us) and monoclonal antibodies. If other products arise from research that
we fund, certain researchers will become entitled to royalties under the terms
of their agreements with us.

Typically, our research agreements oblige us to fund research in amounts to be
determined between the parties. The researchers are responsible for filing
progress reports with us. We work with these researchers and with specialized
consultants on matters such as product formulation, stability, clinical trials
and regulatory matters. In addition, we operate a development center in
Kettering, United Kingdom. Our Kettering facility is responsible for monitoring
Phase III clinical trials in the United Kingdom and Europe, European product
licensing applications and European regulatory approvals.

Our research and development expenditures amounted to $2,702,000, $7,980,000 and
$5,026,000 for 1999, 1998 and 1997, respectively. For more information see Item
7 - "Management's Discussion and Analysis of Financial Condition and Results of
Operations."

MANUFACTURING AND MARKETING

General

In the case of any emerging products, we anticipate that manufacturing and
marketing activities may be arranged through co-development and marketing
agreements with companies which have already established a majority presence in
specialized fields. In this event, any revenues will arise primarily through
third party distribution or licensing arrangements or co-ventures whereby we
will seek to receive a percentage of sales, license fees and/or milestone
payments in consideration for our grant of specified marketing rights to our
products, or by profit participation through third party equity investments or
joint ventures.

Invicorp(TM)

The active materials, vasoactive intestinal polypeptide and phentolamine
mesylate, for the Invicorp(TM) are currently available in commercial quantities
from two suppliers. In conjunction with Senetek, these suppliers have developed
synthetic methods which are included in the product licensing applications. We
rely on these specialized suppliers for continued supply of materials.

Skincare

We outsource the manufacture, filling and labeling of our skincare and health
and beauty products. All our skincare and health and beauty products are sold
within the North American Free Trade Area and Asia through our marketing
partners covering the professional, multi-level marketing, naturals and
specialty mass markets. We have signed distribution agreements for distribution
within the U.S. and abroad. We do not significantly rely on any specialized
suppliers for our skincare and health and

                                       6
<PAGE>

beauty products, and we do not anticipate that problems will arise over access
to raw materials that are generally available and that will be required for our
contract manufacturing processes.

Monoclonal Antibodies

In accordance with an agreement entered into with the Research Foundation for
Mental Hygiene Inc., we have been granted the exclusive right to certain of the
Foundation's cell lines capable of producing certain monoclonal antibodies,
including those applicable to Alzheimer's disease. We continue to sell these
antibodies, which are sourced from outside suppliers, to the scientific
community for research purposes in consideration for a royalty entitlement in
favor of the Foundation. We rely on the sourcing of the monoclonal antibodies
from a specific biotech organization at the present time.

COMPETITION

General

The biopharmaceutical, pharmaceutical and cosmeceutical industries are highly
competitive. Our business and research efforts compete with drug discovery
programs at biotechnology, drug delivery, biopharmaceutical and pharmaceutical
companies, as well as with internal drug discovery efforts of pharmaceutical
companies acting independently or in collaboration with other companies. In
addition, academic institutions, government agencies throughout the world and
public and private organizations conducting research may seek intellectual
property protection, discover competing products, or establish collaborative
arrangements in our area of research and development.

The vast majority of our existing or potential competitors have substantially
greater financial, technical and human resources and name recognition than we
do. These competitors are often better equipped to research, develop, patent,
conduct pre-clinical testing and human clinical trials, manufacture, and market
products. In addition, many of these companies have extensive experience in
pre-clinical testing and human clinical trials. These companies may develop,
license or acquire products that compete with our products. The timing of the
market introduction of our and our competitors' products will be important
competitive factors. Accordingly, the relative speed with which we can develop
products and technologies, complete pre-clinical testing, conduct human clinical
trials, initiate the necessary regulatory approval processes, and supply
commercial quantities of the products to the market will be critical to our
success.

We cannot predict the extent to which any of the products we are currently
developing may become commercially viable. Once products have been approved for
sale, we believe that competition will be based, among other things, on product
efficacy, product safety, product reliability, price and patent position. Our
competitive position also depends upon our ability to attract and retain
qualified and experienced personnel to develop proprietary products, processes
or technologies that we can market and sell and the degree of intellectual
property protection obtainable for those products. We expect competition to
intensify in all fields in which we are involved as new products in these areas
are developed and become more widely known. Moreover, the patent situation in
this field is complex, and the protection afforded by patents in any particular
jurisdiction may be limited.

Invicorp(TM)

Management is presently engaged in discussions with the objective of entering
into licensing arrangements with pharmaceutical companies. Products that compete
with Invicorp( have been or are being developed by our competitors, include
Pfizer ("Viagra"), Pharmacia & Upjohn ("Caverject") and Vivus ("Muse"). Although
our management believes that there will be a substantial demand for
Invicorp(TM), we cannot assure that Invicorp(TM) or future products will obtain
necessary regulatory approvals or that we will be able to successfully market
these products.

Skincare

The vast health and beauty care market is dominated by large multi-national

                                       7
<PAGE>

organizations, who have far greater resources and market exposure than we do.

Our non-Kinetin products are designed to meet specific niche segments of the
market. Our products include the Mill Creek line, Sleepy Hollow Botanicals and
Biotene H-24. The specialty mass market lines are Silver Fox (a product for gray
hair) and the Allercreme Hypoallergenic range for sensitive skins, that was
developed in conjunction with dermatologists and are currently being marketed
under a distribution agreement entered into with Quinlam Inc. This agreement
provides for minimum purchase order guarantees.

Products containing Kinetin are designed to meet the requirements of the
professional, prestige, multi-level and mass markets, internet channel of
distribution, salon and esthetician, and natural market. The products are
currently sold under license and supply agreements with ICN Pharmaceuticals
Inc., Osmotics Corporation and OMP for the prestige, ethical and mass market in
limited territories. Senetek is actively pursuing additional marketing partners
for the other channels of distribution and territories.

GOVERNMENT REGULATION

General

Our research, pre-clinical development, clinical trials, manufacturing and
marketing of its products are subject to extensive regulation, rigorous testing
and approval processes of the FDA and equivalent foreign regulatory agencies.

Product Approval--U.S.

In the U.S., the Federal Food, Drug and Cosmetic Act and the Public Health
Service Act governs the testing, manufacture, safety, efficacy, labeling,
storage, record keeping, approval, advertising, and promotion of our products.
Product development and approval within this regulatory framework takes a number
of years and involves the expenditure of substantial resources. Many products
ultimately do not reach the market because of toxicity or lack of effectiveness
as demonstrated by required testing. In addition, there can be no assurance that
this regulatory framework will not change or that additional regulations will
not arise at any stage of our product development that may affect approval,
delay an application, or require additional expenditures.

The steps required before a pharmaceutical product may be marketed in the U.S.
include:

      o     preclinical laboratory testing;

      o     submission to the FDA of an Investigational New Drug application
            which must become effective before human clinical trials may be
            commenced;

      o     adequate and well-controlled human clinical trials to establish the
            safety and efficacy of the drug;

      o     submission of a New Drug Application to the FDA; and

      o     FDA approval of the New Drug Application prior to any commercial
            sale or shipment of the drug.

Invicorp(TM) has received Investigational New Drug approval from the FDA, and we
plan to file a New Drug Application with the FDA for Invicorp(TM) at the
earliest practicable opportunity.

Clinical testing of new compounds in humans is designed to establish both safety
and efficacy in treating a particular disease or condition. These studies are
usually conducted in three phases of testing. In Phase I, a small number of
volunteers are given the new compound in order to identify toxicities and
characterize the compound's behavior in humans. In Phase II, small numbers of
patients with the targeted disease are given the compound to test its efficacy
in treating the targeted disease and to establish dose levels. Phase III
studies, which we have

                                       8
<PAGE>

concluded for Invicorp(TM), are large-scale studies designed to confirm a
compound's efficacy for the targeted disease and identify toxicities that might
not have been seen in smaller studies. Once adequate data has been obtained in
clinical testing to demonstrate that the compound is both safe and effective for
the intended use, all available data is submitted to the FDA as part of the New
Drug Application.

Our clinical trials for future products will generate safety data as well as
efficacy data and will require substantial time and significant funding. We
cannot assure that clinical trials related to future products would be completed
successfully within any specified time period, if at all. Furthermore, the FDA
may suspend clinical trials at any time if it is believed that the subjects
participating in such trials are being exposed to unacceptable health risks.

Under current regulations, the market introduction of non-medicated cosmetics
and skin care products do not require prior formal registration or approval by
the FDA, although this could change in the future. The Cosmetics Division of the
FDA monitors matters of safety and adulteration. The situation for non-medicated
cosmetic and skin care products is the same for Europe.

Product Approval - Other Countries

Marketing of products in other countries requires regulatory approval from the
relevant medicines evaluation in a particular country. The current approval
process varies from country to country, and the time to approval may vary from
that required for FDA approval. The review of clinical studies by regulatory
agencies in foreign jurisdictions follows a similar process to that in the U.S.

Invicorp(TM) was approved for marketing in Denmark in July 1998. In December
1998 we received news from the Medicines Evaluation Agency in Ireland that
Invicorp(TM) had received clearance on safety and efficacy grounds and we are
waiting for final approval. In March 1999, the United Kingdom's Committee on
Safety of Medicines informed us that it was prepared to advise the United
Kingdom's licensing authority to grant a marketing authorization for
Invicorp(TM) upon our compliance with specified conditions. On January 31,2000
we filed an amendment that addressed all the conditions cited by the MCA. During
May 1999 we were notified by New Zealand s Medicines Assessment Advisory
Committee that they had recommended Invicorp(TM) be approved for the treatment
of Erectile Dysfunction. We are awaiting approval of marketing authorization
applications for Invicorp(TM) in the Republic of Ireland, Switzerland and South
Africa. We anticipate approvals from the United Kingdom and Ireland during the
second half of 2000. However, these applications will be subject to rigorous
approval processes. We cannot assure that approval in these or other countries
will be granted or that these approvals if granted, will not contain significant
limitations in the form of warnings, precautions or contraindications with
respect to condition of use. Any delay in obtaining, or failure to obtain such
approval would adversely affect our ability to generate product revenue.

In addition, in certain European countries, the sales price of a product must be
approved. The pricing review period often begins after market approval is
granted.

Noncompliance

Failure to comply with the applicable regulatory requirements can, among other
things, result in fines, suspensions of regulatory approvals, product recalls,
operating restrictions and criminal prosecution. In addition, the marketing and
manufacturing of pharmaceutical products are subject to continuing FDA and other
regulatory review, and later discovery of previously unknown problems with a
product, manufacturer or facility may result in the FDA and other regulatory
agencies requiring further clinical research or restrictions on the product or
the manufacturer, including withdrawal of the product from the market. The
restriction, suspension or revocation of regulatory approvals or any other
failure to comply with regulatory requirements would have a material adverse
effect on our business, financial condition and results of operations.

Post-Approval

After regulatory approval is obtained, our products are subject to continual

                                       9
<PAGE>

review. Manufacturing, labeling and promotional activities are continually
regulated by the FDA and equivalent foreign regulatory agencies, and we must
also report certain adverse events involving our drugs to these agencies.
Previously unidentified adverse events or an increased frequency of adverse
events that occur post-approval could result in labeling modifications of
approved products, which could adversely effect future marketing of a drug.
Finally, approvals may be withdrawn if compliance with regulatory standards is
not maintained or if problems occur following initial marketing. The
restriction, suspension or revocation of regulatory approvals or any other
failure to comply with regulatory requirements would have a material adverse
effect on our business, financial condition and results of operations.

We obtain certain materials and components for the manufacture of our products
from third parties. In addition, we out-source the manufacture of certain
products (see "Business--Manufacturing and Marketing"). These parties are
required to comply with strict standards established by us. Certain
manufacturers and suppliers are required by the Federal Food, Drug, and Cosmetic
Act, as amended, and by FDA regulations, to follow Good Manufacturing Practices,
or GMP, requirements and are subject to routine periodic inspections by the FDA
and certain state and foreign regulatory agencies for compliance with GMP and
other applicable regulations. Upon routine inspection of these facilities, we
cannot assure that the FDA and other regulatory agencies will find the
manufacturing process or facilities to be in compliance with GMP and other
regulations. Failure to achieve satisfactory GMP compliance as confirmed by
routine inspections could have a material adverse effect on our ability to
continue to manufacture and distribute our products and, in the most serious
case, result in the issuance of a regulatory warning letter or seizure or recall
of products, injunction and/or civil fines or closure of our manufacturing
facility until GMP compliance is achieved.

Import Restrictions and Duties

Because Senetek may be importing certain of its products or product ingredients
into the United States, Senetek could be subject to quantity limitations, duties
and tariffs imposed by countries in which the products are to be sold. The
United States does not have quantity restrictions for goods such as Senetek's
proposed products but does impose tariffs based on the value of the products
imported. Other countries may have different restrictions and duties.

PATENTS

We believe that patents and other proprietary rights are an essential element of
our business. As part of our grant agreements with various researchers, we have
exclusive license rights to any commercially valuable products developed by the
contracted researchers within the scope of the agreements, in exchange for
royalty entitlements. Our policy is to file patent applications to protect
inventions and improvements that we consider important to the development of our
business. Typically, patents in the U.S. expire 17 years after the grant date.

We also rely upon trade secrets, know-how, continuing technological innovations
and licensing opportunities to develop and maintain our competitive position. We
have filed patent applications for our products in most major countries,
including those that are signatories to the Patent Conference Treaty. Thus far,
our technology is patented in most of these countries (which include US, Canada
and the major European countries) and in major areas in Asia and South America.
We have also received patent approvals covering our technology in the following
areas:

            o     Two patents for Invicorp(TM) for the use of vasoactive
                  intestinal polypeptide and phentolamine mesylate in the
                  treatment of Erectile Dysfunction have been granted in 15
                  countries and are pending in 13 other countries.

            o     Three patents for Kinetin and Zeatin for ameliorating the
                  effects of aging on skin have been granted in 29 countries and
                  are pending in 13 other countries.

                                       10
<PAGE>

            o     Two patents for Kinetin and Zeatin for ameliorating the
                  effects of hyperproliferative skin diseases, including
                  psoriasis have been granted in 29 countries and are pending in
                  13 other countries.

            o     Three autoinjector patents for the delivery of therapeutic
                  ingredients have been granted in 28 countries and are pending
                  in 18 other countries.

Patent positions generally, including those for pharmaceutical and health
service organizations such as us, are uncertain and involve complex legal and
factual questions for which important legal principles are largely unresolved.
In addition, the coverage claimed in a patent application can be significantly
reduced before a patent is issued. Consequently, we cannot be sure that any
patents that are or may be issued to us will provide significant proprietary
protection or will not be circumvented or invalidated. Because patent
applications in the U.S. are maintained in secrecy until patents issued, and
publication of discoveries in the scientific or patent literature often lags
behind actual discoveries, we cannot be certain that we or any licensor was the
first creator or that we or our licensor was the first to file patent
applications for these inventions. Moreover, we might have to participate in
interference proceedings declared by the U.S. Patent and Trademark Office to
determine priority of inventions, which could result in substantial cost to us,
whether or not the eventual outcome was favorable to us. We cannot assure that
our patents, if issued, would be held valid by a court or that a competitor's
technology or product would be found to infringe such patents.

A number of pharmaceutical and health services companies and research and
academic institutions have developed technologies, filed patent applications, or
received patents in areas that may be related to our business. Some of these
Technology applications or patents may conflict with our development efforts or
patent applications.

We have been granted trademark protection for our major brand names in 14
countries and have applications pending in 20 others. To the best of our
knowledge, there has been no indication to date that such trademarks are invalid
or are subject to challenge.

Typically, we require our employees, consultants and sponsored researchers to
execute confidentiality agreements as part of their employment, consulting or
research arrangements with us. We cannot assure, however, that these agreements
will produce meaningful or adequate protection for our trade secrets.

EMPLOYEES

As of December 31, 1999, we employed 13 full-time persons. Senetek PLC employees
comprised 2 persons at our drug development center at Kettering in the United
Kingdom, and nine in the U.S., all of whom are employed in our Napa
headquarters. As of December 31, 1999, our wholly owned subsidiary, Senetek Drug
Delivery Technologies, Inc., employed one person in the U.S. who concentrates on
the scientific, engineering and production aspects of evaluating new drug
delivery technologies. Our other wholly owned subsidiary, Carme Cosmeceutical
Sciences Inc., has one U.S employee covering the supply chain requirements of
our skincare and health and beauty products.

ITEM 2--PROPERTIES

We lease approximately 31,000 square feet in Napa, California for our U.S.
headquarters. Our headquarters facility includes approximately 7,300 square feet
of manufacturing space and 23,700 square feet of research, marketing and
administrative space. Our lease for the Napa facility expires in December 2007.
We also lease an approximately 5,000 square foot building in Kettering, United
Kingdom under a 15-year lease with a break option after five years. We have
sublet approximately 2,250 square feet of this space to two unaffiliated
companies. We believe that our leased facilities are adequate for our current
operations.

ITEM 3--LEGAL PROCEEDINGS

                                       11
<PAGE>

On June 11, 1998 we filed a lawsuit against Mad Dogs & Englishmen Inc. and Mad
Dog Enterprises d/b/a Mad Dogs & Englishmen (together "Mad Dogs") in the Supreme
Court of New York.  On December 11, 1996 we entered into a written agreement
with Mad Dogs under which Mad Dogs  agreed to promote our cosmetics business and
to hire a consultant familiar with the Cosmetics industry in connection
therewith.  We are seeking damages of approximately $10 million for a breach of
that agreement.  MadDogs served us with an answer to our complaint in August
1998.  There have been no substantive developments in the lawsuit since the
filing of the answer to our complaint.

During January 2000, Senetek and CCSI terminated the licensing agreement with
Osmotics Corporation for multiple breaches of contract, including non-payment of
royalties and selling outside its authorized channel of distribution. The
dispute is now pending before the American Arbitration Association (AAA). In
February 2000, Osmotics Corporation simultaneously instituted proceedings before
the AAA and in state court in Colorado, seeking injunctive and declaratory
relief, on the grounds that Senetek and CCSI wrongly terminated the license
agreement. Senetek and CCSI successfully removed the case to the United States
District Court for the District of Colorado. The federal court dismissed the
complaint with prejudice, ruling that the matter must first be decided by the
AAA, pursuant to the arbitration provisions of the license agreement. In the AAA
proceeding, Senetek and CCSI have filed a counterclaim for breach of contract
and patent infringement, on grounds that Osmotics breached the contract by
failing to pay royalties and selling outside its authorized channel of
distribution (department stores and perfumeries). Senetek and CCSI have also
moved for interim relief, seeking an injunction prohibiting Osmotics from
selling Kinetin products and the imposition of a constructive trust on past due
royalties. The dispute will be decided by a panel of AAA arbitrators in Los
Angeles, California. Management does not feel that the termination of the
Osmotics license agreement, nor the AAA dispute, will have a material adverse
effect on the company.

None.

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

(a)   GENERAL DISCUSSION

      There is currently no established public trading market for our Ordinary
      shares in the United Kingdom. Our American Depositary shares (each
      representing one Ordinary share and evidenced by one American Depositary
      Receipt) were traded on the over-the-counter market in the United States
      beginning in November 1984 and have been traded through The Nasdaq Stock
      Market since our public offering in the U.S. in May 1986.

      The following table sets out the range of high and low closing bid prices
      for our American Depositary shares during each quarter of our two most
      recent fiscal years, as reported by the Nasdaq Smallcap Stock Market.

      FISCAL YEAR ENDED DECEMBER 31, 1999

        QUARTER ENDED:                                 HIGH           LOW

      As of March 20, 2000 there were approximately 217 holders of record of our
      Ordinary shares, including approximately 1,014 holders of record of
      American Depositary shares. The share price at March 20, 2000 was a high
      of $2.94 and a low of $2.47.

      We have not paid, nor do we presently contemplate the payment of, any cash
      dividends on our Ordinary shares. The decision whether to pay, and the
      amount of such dividends, will be based upon, among other things, our
      earnings, capital requirements and financial conditions. Any dividend,
      either cash or stock, must be recommended by our board of directors and
      approved by our shareholders. The board of directors is, however,
      empowered to declare interim dividends. Under the English Companies Act of
      1985, a limited company may not declare or pay cash dividends while it has
      an accumulated deficit. We had an accumulated deficit of $83,830,000 at
      December 31, 1999. Accordingly, we will not be in a position to consider
      the question of dividends until the accumulated deficit has been absorbed
      by profits or by the application against the deficit with the approval of
      stockholders and the United Kingdom Companies' Court, which forms part of
      the Chancery Division of the High Court, of an equivalent figure forming
      part of the share premium on our balance sheet.

(b)   SALES OF UNREGISTERED SECURITIES

      FISCAL 1999

(c)   TAXATION

      General

      The following is a summary of the principal U.S. federal and United
      Kingdom tax consequences applicable to the ownership of Ordinary Shares
      and American Depositary shares, by a beneficial holder that is a citizen
      or resident of the United States, a corporation or partnership created or
      organized under the laws of the U.S. or any state thereof or that
      otherwise is subject to U.S. Federal income tax on a net income basis in
      respect of the Ordinary shares or American Depositary shares (a "U.S.
      Holder"). This summary is not exhaustive of all possible tax
      considerations, and U.S. Holders are advised to consult their own tax
      advisers as to the overall tax consequences, including specifically the
      consequences under state and local laws, of the purchase, ownership and
      disposition of Ordinary shares or American Depositary shares.

      This summary does not address the United Kingdom tax consequences to a
      U.S. Holder who is resident or (in the case of an individual) ordinarily
      resident in the United Kingdom or who carries on business there through a
      branch or agency. A disposition of Ordinary shares or American Depositary
      shares, by such a person may be subject to United Kingdom tax.

      This summary also does not address the U.S. tax consequences to a U.S.
      Holder (i) controlling, directly or indirectly, together with affiliates
      and associates, 10% or more of the voting shares of Senetek PLC, (ii) who
      does not hold the Ordinary shares or American Depositary shares as capital
      assets, (iii) who does not use the U.S. dollar as the U.S. Holder's
      functional currency or (iv) who holds the Ordinary shares or American
      Depositary shares as part of a larger integrated financial transaction or
      straddle.

      The statements regarding U.S. federal and United Kingdom tax laws set out
      below are based on those laws as in force on the date of this Form 10-K.

      For the purposes of the current U.S./United Kingdom double taxation
      conventions (the "Income Tax Convention") and for the purposes of the U.S.
      Internal Revenue Code of 1986, as amended (the "Code"), U.S. Holders of
      American Depositary shares will be treated as owners of the underlying
      Ordinary shares.

      Taxation of Dividends

      No tax will be withheld from dividend payments by Senetek PLC to United
      Kingdom resident shareholders. An individual shareholder resident in the
      United Kingdom is treated for United Kingdom tax purposes as having
      taxable income equal to the sum of the dividend plus a tax credit equal to
      10% of the sum of the dividend plus the tax credit (such aggregate sum
      being hereinafter referred to as the "Gross Dividend"). The tax credit is
      available as a tax credit against the individual's tax liability on the
      relevant dividend.

      Prior to April 6, 1999, U.S. resident shareholders were normally entitled
      to a refund from the United Kingdom Inland Revenue of taxation as a result
      of the dividends paid to them. After April 6, 1999, a corporate U.S.
      Holder (which is not also a resident of the United Kingdom or

                                       15
<PAGE>
      the purposes of the Income Tax Convention) who controls, directly or
      indirectly (either alone or with one of more associated Corporations) 10%
      or more of the voting power of Senetek PLC may still apply for a refund
      but generally other shareholders may not.

ITEM 6--SELECTED FINANCIAL DATA

The selected consolidated statement of operations data presented below for each
of the years in the three-year period ended December 31, 1999 and the selected
consolidated balance sheet data as of December 31, 1998 and 1999 has been
derived from and should be read in conjunction with our financial statements
included in Part IV of this Report on Form 10-K. The selected consolidated
statements of operations data for the years ended December 31, 1995 and 1996 and
the selected consolidated balance sheet data as of December 31, 1995, 1996 and
1997 has been derived from the audited financial statements contained in our
annual reports to shareholders.

ITEM 7--MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

GENERAL

We received our initial funding from a public issuance of Ordinary shares in the
United Kingdom in November 1983. In May 1986, we completed a public financing in
the U.S. resulting in the issuance of 1,322,500 Units, each consisting of one
Ordinary share and one "A" and one "B" warrant for the purchase of an equivalent
number of Ordinary shares. The Ordinary shares were issued as American
Depositary shares, evidenced by American Depositary Receipts, and together with
the "A" and "B" warrants, were traded under the Nasdaq Automated Quotations
System. 143,018 unexercised "A" and 1,285,400 unexercised "B" warrants ceased
trading upon the lapsing of their respective extended exercise dates in May
1997. Since May 1986, we have relied on private placements of Ordinary shares,
convertible debentures and warrants to add to our capital base.

Our accounts set forth in Part IV of this Report have been prepared in
accordance with U.S. generally accepted accounting principles (U.S. GAAP). Our
financial information included in this Form 10-K is presented in U.S. dollars.

MATERIAL CHANGES IN FINANCIAL CONDITION

During the year ended December 31, 1999, our liquid position, represented by
cash and deposits at banks and liquid investments, increased by $1,032,000 to
$1,840,000. This increase is attributable to the excess of net proceeds from the
issue of new investment notes over operational losses, movements in net working
capital and capital expenditure as discussed in "Liquidity and Capital
Resources" below.

RESULTS OF OPERATIONS

Our operations are carried out in the areas of pharmaceuticals development and
drug delivery systems development ("pharmaceuticals") and the supply of skincare
products ("cosmeceuticals") to licensees.

REVENUES

Our product sales revenues of $8,263,000 for the year ended December 31, 1999
comprised $259,000 from the sale of named patient products, $1,042,000 from the
sale of monoclonal antibodies, and $6,962,000 from the sale of skincare
products.

Our product sales revenues of $4,672,000 for the year ended December 31, 1998
comprised $401,000 from the sale of named patient products, $1,116,000 from the
sale of monoclonal antibodies, and $3,155,000 from the sale of skincare
products.

The overall sales increase of 76.9% was represented by an increase of skincare
sales of 121% and a decrease in pharmaceutical sales, comprising named patient
sales and monoclonal antibodies sales of 14.2%

                                       18
<PAGE>

The 35.4% decrease in sales of named patient products is due to temporary
suspensions of named patient sales of Invicorp(TM) in the United Kingdom. This
was done following a possible batch sterility problem with our contract
manufacturer and possible toxicological findings on phentolamine mesylate
submitted to the FDA by a competitor. This competitor is also developing an
erectile dysfunction product. The UK Medicines Control Agency supported the
resumption of named patient sales after reviewing the FDA findings and our
initial response.

The 6.6% decrease in sales of monoclonal antibodies was mainly due to lower
volumes of sales in the first quarter of 1999. Sales of monoclonal antibodies,
some of which are used for the early diagnosis of Alzeimers disease, follow
sales patterns determined by project driven research organizations and are
subject to fluctuation.

The 121% increase in sales of skincare products was mainly due to sales of
Kinetin products to ICN Pharmaceuticals Inc. under a licensing and supply
agreement entered into in the fourth quarter of 1998. Under this agreement, ICN
has agreed to sell and distribute a product called Kinerase to the professional
dermatological market in North America.

In May 1999, exclusive rights for the worldwide distribution of Mill Creek(R)
and Silver Fox(R) products were granted to United States International Trading
Corporation ("USITC"). In return for the grant of the distribution rights, CCSI
received a $100,000 license fee and will receive guaranteed minimum quarterly
royalties based on net sales from September 1999. CCSI also sold its trading
inventories to USITC for $348,000.

On December 15, 1999, we entered into a license and supply agreement with Obaji
Medical Products for the exclusive marketing and distribution of Kinetin
products in the mass marketing channel of distribution in a number of major
Asian countries. Also, Obaji receives exclusivity for Kinetin in the multi level
marketing channel of distribution in Taiwan. For the grant of the distribution
rights the agreement calls for Senetek to receive $1,150,000 license fees. Of
this, we received $450,000 in 1999 and we expect the balance to be received in
2000. We have recorded these fees as deferred income and will recognize revenue
under the terms of the agreement.

Our sales revenues of $5,722,000 for 1997 comprised $276,000 from the sale of
Named patient products, $891,000 from the sales of monoclonal antibodies and
$4,555,000 from the sale of skincare products.

The overall sales decrease of 18.4%, comparing 1998 to 1997 was represented by
an increase in pharmaceutical sales, comprising named patient sales and
monoclonal antibodies sales of 30% and a decrease in skincare sales of 30.7%.

The 45.3% increase in named patient sales was due to a 37.3% increase in volume
and an 8% increase in price. The 25.3% increase in sales of monoclonal
antibodies was due to an increase in sales volume. The 30.7% decrease in sales
of skincare products was due to the efficient streamlining of the product line
by eliminating low gross margin products.

COST OF SALES

Cost of goods sold for the year ended December 31, 1999, which includes contract
manufacturing and material costs, was $3,044,000, up 0.1% from the year ended
December 31, 1998. Due to increased sales of high margin products, Cost of goods
sold as a percentage of sales was 37% for the year ended December 31, 1999
compared to 65% for year ended December 31, 1998. The cost of goods sold as a
percentage of sales decrease is due to increased sales of higher margin
products-especially Kinetin products. This follows the launch of Kinerase
products by ICN Pharmaceuticals in the dermatological sector of the skincare
market towards the end of the first quarter of 1999.

In the Pharmaceutical Sector, cost of goods sold for the year ended December 31,
1999 was $560,000, down 8.3% from $611,000 from the year ended December 31,
1998. This is due mainly to a decrease in sales volume following the temporary
suspension of Invicorp(TM) named patient sales in the United Kingdom.

                                       19

In the Skincare Sector, cost of goods sold for the year ended December 31, 1999
was $2,484,000, an increase of 2.3% from $2,429,000 for the year ended December
31, 1998. This is mainly due to the effect of increased sales volumes and a
favorable change to high margin products in the sales mix, following the launch
of the Kinerase products in March 1999.

RESEARCH AND DEVELOPMENT

Pharmaceutical Division

Research and development expenses in the year ended December 31, 1999 were
$2,639,000, compared with $7,955,000, and $4,914,000 in 1998 and 1997,
respectively.

The decrease of $5,316,000 in 1999 compared with 1998 was primarily due to:

      o     Substantially reduced levels of Phase 111 clinical trials for
            Invicorp(TM) as these reach completion in Europe and we receive
            Marketing Authorization Approvals
      o     Reduction in headcount of 4 persons in Senetek research and
            development US in the third quarter of 1999 and the closure of our
            St Louis facility. Reduction in headcount of 5 persons in Senetek
            research and development UK in the second quarter of 1999. Reduction
            in headcount of 2 persons in SDDT research and development in the
            third quarter of 1999
      o     One time purchase of vasoactive intestinal polypeptide and
            phentolamine mesylate for $1,200,000 in 1998
      o     Reduced spending levels on Reliaject(TM) and Invicorp(TM) in the
            fourth quarter of 1999 as we developed a new drug delivery strategy
            for Invicorp(TM) utilizing a cost effective, state of the art
            delivery system.
      o     Reduced levels of external consultancy in the area of regulatory
            affairs

The increase of $3,041,000 in 1998 compared with 1997 was primarily due to:

      o     Further spending on pivotal clinical studies, toxicology studies
            (including a transgenic mouse carcinogenicity study) and regulatory
            affairs for our Invicorp(TM) and Adrenaject(TM) products
      o     One time purchase of vasoactive intestinal polypeptide and
            phentolamine mesylate for $1,200,000 in 1998

Skincare Division

Research and development expenses in the year ended December 31, 1999 were
$63,000 compared with $25,000 and $112,000 in 1998 and 1997, respectively.

The increase of $38,000 in 1999 compared with 1998 is mainly due to additional
formulation work undertaken on our Kinetin plus products.

The decrease of $87,000 in 1998 compared with 1997 was primarily due to the
streamlining of our cosmetic product portfolio and the elimination of production
development expenses following the decision to outsource manufacturing in the
second quarter of 1997.

GENERAL AND ADMINISTRATIVE

Pharmaceutical Division

General and administrative expenses totaled $4,290,000 for 1999, compared with
$7,482,000 and $6,169,000 for 1998 and 1997, respectively.

The decrease of $3,192,000 in 1999 compared to 1998 was primarily due to:

      o     This decrease is mainly due to the net savings arising from the
            corporate consolidation and cost reduction program. The main results
            of the program were the substantial reduction of our headcount and
            the consolidation of offices mentioned below. We incurred one time
            costs in our Corporate restructuring program, which was launched at
            the beginning of 1999. In May 1999 we closed our UK, London
            operations and combined those functions in

                                       20
<PAGE>

            our UK Kettering office. We also pared down our UK clinical
            monitoring and development staff and have substantially moved these
            functions to our Napa office. The reduction in headcount was 6
            people and the severance packages of $125,000 which included full
            settlement with a former Director, were expensed in the second
            quarter of 1999. Also, during the third quarter of 1999 we closed
            our St Louis research facility and transferred their functions to
            Napa. There were no significant one time costs incurred, arising
            from the closure of the St. Louis facility. The financial impact of
            the St Louis closure are annualized savings of approximately
            $300,000 in salaries and office overheads. Furthermore, we settled
            our legal disputes with a former director and consultant and
            recognized the settlement costs of $77,000 in the second quarter of
            1999. Also, in the third quarter we executed Release and Separation
            agreements with our former Chairman and CEO and our former President
            and COO both of whom left our employment towards the end of the
            fourth quarter 1998. In the case of the Chairman and CEO there were
            no settlement costs and 1.5 million stock options were cancelled. In
            the case of the President and COO we settled outstanding expenses of
            $23,000 and cancelled 500,000 stock options. We also incurred in the
            second quarter of 1999 expenses of $140,000 relating to the write
            off of expense advances for former employees. Legal costs of
            $1,458,000 relating primarily to the settlements of disputes arising
            from commitments made by former management to lenders, together with
            disputes with former employees and consultants and, to a lesser
            extent, the April financing arrangements, were incurred in the
            second, third and fourth quarters of 1999.

      o     In 1999 we recognized a charge to stock compensation expense of
            $77,000 as compared to $2,278,000 in 1998. The 1999 expense is
            reconciled as follows: (1) stock compensation expense $376,000 for
            employee based stock option plans in accordance with Accounting
            Principle Board Opinion No. 25 ("APB 25") and $776,000 for non
            employee based stock option plans in accordance with Statement of
            Financial Accounting Standard No 123 ("FAS 123") and (2) reversal of
            previously recorded stock compensation expense on the cancellation
            of non vested options of $1,075,000.

      o     Offsetting the net savings mentioned above were provisions for
            doubtful debts of $582,000.

The increase of $1,313,000 in 1998 compared to 1997 was primarily due to:

      o     The full year effect of retaining a public relations company in the
            second half of 1997 to focus on investor relations and development
            status of the Invicorp(TM) and Kinetin products; and

      o     The full year effect of retaining a consulting company in the second
            half of 1997 to focus on product licensing opportunities for
            Invicorp(TM) with potential pharmaceutical partners and the setting
            up of raw material supply and contract manufacturing arrangements
            for Invicorp(TM) supply chain.

We recognized $2,278,000 of employee stock compensation expense in accordance
with APB 25 and FAS 123 in fiscal 1998 compared to $3,438,000 of employee stock
compensation expense in fiscal 1997.

Skincare Division

General and administrative costs for the year ended December 31, 1999 were
$2,134,000, compared with $1,680,000 and $1,762,000 for 1998 and 1997,
respectively. The 1998 costs reflect stock compensation expense relating to the
grant of employee stock options in 1997, which vest in 1999, and beyond, in
accordance with APB 25.

The increase of $569,000 in 1999 compared to 1998 was mainly due to costs
incurred in relation to the new license and supply arrangements and provision
for bad debts.

The decrease of $82,000 in 1998 compared to 1997 was primarily due to decreased
operating costs of CCSI following the outsourcing of manufacturing in 1997.

MARKETING AND PROMOTION

                                       21
<PAGE>

Pharmaceutical Division

Marketing and promotion expenses totaled $272,000 for 1999, compared with
$847,000 and $2,149,000 for 1998 and 1997, respectively.

The $575,000 decrease in 1999 compared to 1998 is mainly due to the elimination
of external consulting arrangements and non essential advertising expenditure.

The $1,302,000 decrease in 1998 compared to 1997 was mainly due to a reduction
in corporate advertising and marketing communication costs in relation to the
Invicorp(TM) and Reliaject(TM) developments.

Skincare Division

Marketing and promotion expenses totaled $118,000 for 1999, compared with
$276,000 and $1,376,000 for 1998 and 1997, respectively.

The decrease of $158,000 in 1999 compared to 1998 was mainly due to the
implementation of a focused marketing plan, which resulted in all the skincare
product lines coming under third party licensing arrangements.

The decrease of $1,100,000 in 1998 compared to 1997 was mainly due to one time
advertising costs associated with the promotion of Kinetin products in 1997.

SELLING EXPENSES

Skincare Division

Selling expenses relating to our skincare products totaled $Nil for 1999,
compared with $456,000 and $742,000 for 1998 and 1997, respectively.

No field selling expenses have been recorded during 1999. This is due to the
establishment of licensing and distribution arrangements in the skincare sector
and the elimination of direct selling activities.

The decrease of $286,000 in 1998 compared to 1997 was primarily due to reduced
salaries and broker commissions following the streamlining of the product
portfolio in 1998.

IMPAIRMENT COSTS

In December 1999, the Company abandoned certain fixed assets. As a result of
this abandonment, the Company recorded an impairment loss of $1,522,000. The
assets written down comprised of assets in progress associated with the
Reliaject( development and computers and office equipment. The pharmaceutical
and skincare business segments were written down by $1,407,000 and $115,000
respectively.

OTHER INCOME AND EXPENSE

In April 1999, the Company received $4,751,000 (net of $249,000 in expenses) in
cash and refinanced the balance owed of $2,389,000 under a 1998 Credit
Agreement, in exchange for two new notes that currently bear interest at 9% per
annum and mature in April 2002. The notes require semi annual payment of
interest only until maturity and are secured by all of the Company's assets.
Interest may be paid in cash or in Ordinary shares that have been registered
with the SEC.

The Company issued Series A warrants to purchase an aggregate of 738,857
Ordinary shares at $1.50 per share, which were adjusted down to $1.20 in
accordance with certain terms of the agreement under which they were issued. The
Series A warrants expire five years from the date of issuance. Series B and C
warrants to purchase approximately 3.3 million and 1.2 million Ordinary shares
at $1.50 and $2 per share were issued in connection with the Company's 1999
settlement and refinancing agreements are only exercisable to the extent the
outstanding principal balance of $7,389,000 is not repaid in cash. The Series B
and C warrants expire ten years from the date of issuance.

                                       22
<PAGE>

The fair value of 500,000 of the Series A warrants and all of the Series B
warrants was determined to be $3.1 million using the Black Scholes model. The
fair value of these warrants will be amortized over the life of the new notes
because such warrants, under the terms of the financing agreement, were issued
in connection with the $5.0 million new financing. On the other hand, the $1.0
million fair value of the remaining 238,857 Series A warrants and all of the
3,333,333 Series C warrants was included in the loss on extinguishment of debt
discussed below because these warrants were issued to refinance existing debt
under the terms of the April 1999 financing agreement. The amortization of the
deferred finance costs on the $5.0 million new financing amounted to $803,000
for the year.

As the outstanding borrowings under the 1998 Credit Agreement were refinanced by
notes with substantially different terms as defined by EITF 96-19, Debtors
Accounting for a Modification or Extinguishment of Debt Instruments, (EITF
96-19), the Company is required to recognize the difference between the fair
value of the new notes issued to refinance the old debt and the carrying value
of the old debt net of unamoritized issuance costs as a loss on the
extinguishment of debt. During 1999, the Company recognized a $1,657,000 loss on
the extinguishment of debt.

Also, in April 1999 the Company entered into a settlement agreement to resolve
the terms of various transactions that had been entered into by the previous
management of the Company. The settlement terms required the issuance of
2,300,000 Series A warrants and 625,000 new Ordinary shares. Accordingly the
Company recorded $2,718,000 of expense in the second quarter of 1999 related to
the settlement terms. Included in the $2,718,000 settlement expense is the fair
value of the 625,000 Ordinary shares issued in 1999.

Also, included in other expense is $526,000 of external interest expense on the
Company's investment notes.

Refer to Note 16 to the Financial Statements for discussion of the Company's net
operating loss carryforwards.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents increased by $1,032,000 during 1999 to $1,840,000.
This increase is due to the excess of the proceeds of private placements of
shares, convertible debt, the exercise of warrants and the exercise of employee
share options for the year over our operational losses, capital expenditure and
net movements in working capital. To date we have realized only modest revenues
from our operations. We continue, as in the past, to depend upon raising equity
funds from private placements. Our independent auditors report on our
consolidated financial statements included in Item 8 states that
"......[Senetek] has negative working capital and has suffered recurring losses
from its pharmaceutical operations and its ability to continue research
activities to a stage where it has a product available for sale is dependent
upon securing additional sources of financing. These conditions raise
substantial doubt about [Senetek's] ability to continue as a going concern."

In April 1999, we issued $7,389,000 in aggregate principal amount of secured
promissory notes. The notes currently bear interest at a rate of 9.0% per year,
payable semi-annually, and are due and payable in full in April 2002. The
repayment of the notes is secured by all of the assets of Senetek PLC and its
subsidiaries. In exchange for the issuance of the notes, we received $5,000,000
in cash (less expenses) and refinancing of $2,389,000 of our previously
outstanding debt. We also issued warrants to purchase Ordinary shares in
connection with the issuance of the notes. Although we have received no
commitment for the advance of any further funds, other lenders who advance up to
an additional $7,611,430 may share in the collateral securing the notes
described above on pari passu basis with the existing note holders.

Our other most significant revenue commitments are our research agreements,
consulting agreements, employment agreements and property leases.

In the event of the use of Kinetin as a prescription product, as opposed to a
cosmeceutical product, we would have to commit considerable additional
expenditure, and the speed at which this work can be undertaken will depend upon
our financial

                                       23
<PAGE>

resources.

We anticipate spending approximately $9 million during 2000 on the development
of our pharmaceutical and skincare products, including new auto-injector
projects, and on our administrative and marketing operations. Our management is
of the opinion that although we will generate increased revenues from the sale
of our skincare product lines, monoclonal antibodies and the Invicorp(TM)
product to named-patients, these will not be sufficient to meet our short term
financial requirements.

Additionally, certain holders of a substantial number of warrants may exercise
their right to convert their warrants into shares upon payment to us of the
exercise price as the conversion dates approach.

Our management is discussing the possibility of entering into licensing
arrangements with several major pharmaceutical companies. Although these
discussions may lead to a license agreement of a substantial nature in due
course, we cannot assure that we will be successful in securing such an
agreements.

GOVERNMENT POLICY

It is the opinion of our board of directors that there are no aspects of
government policy which, as far as can be foreseen, are likely to have a
material effect on the conduct of our business, except as generally described in
Part I, Item 1, of this Form 10-K under the heading "Government Regulation."

IMPACT OF INFLATION

We believe that inflation has not had any material effect on the results of our
operations to date.

YEAR 2000

The term "Year 2000 issue" is used to describe the various problems that may
result from the improper processing of dates and date-sensitive calculation by
computers and other machinery as the year 2000 approaches. These problems
generally arise from the fact that most of the world's computer hardware and
software have used only two digits to identify the year in a date, often meaning
that the computer will fail to distinguish dates in the "2000's" from those in
the "1900's." This could result in system failure of miscalculations causing
disruptions of operations including, among other things, a temporary inability
to process transactions, send invoices or engage in similar normal business
activities.

In 1998 we had initiated a year 2000 assessment and remediation program. As part
of this program, we have completed an evaluation of our computer systems and
significant software programs, including our network hardware and operating
systems and accounting and business process software and our non-information
technology systems. We also confirmed with our major vendors that they were year
2000 compliant. Our new accounting and business software was purchased with the
year 2000 in mind. This software was year 2000 compliant when purchased. As a
result of our review of all other software and hardware, we made an upgrade to
our information software and no changes to our hardware.

The testing and evaluation process was completed in the fourth quarter of 1999.
As of, January 1, 2000 through March 20, 2000, we have not experienced any
hardware or software problems related to the millennium date change. We do not
anticipate any significant latent software or hardware problems, but we have
retained the company that performed our testing and evaluation an annual
maintenance contract.

FOREIGN CURRENCIES

We have operations in the United Kingdon, where the functional currency is the
pound sterling. The Company follows currency translation principles established
by SFAS No. 52. All assets and liabilities in the balance sheets of the UK
operation are translated at period-end exchange rates. All income and
expenditure items in the profit and loss account of the UK operation are
translated at average monthly exchange rates. Translation gains and
losses arising from the translation of the financial statements of the UK
Operation are not included in determining net income but are accumulated in a
separate component of stockholders' equity <deficit>. Foreign currency
transaction gains and losses are included in the determination of net income in
the period in which they occur. We do not use any methods to hedge the effect of
changes in the pound sterling exchange rate.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 Requires companies to
recognize all derivative contracts as either assets or liabilities in the
balance sheet and to measure them at fair value. If certain conditions are met,
a derivative may be specifically designated as hedge, the object of which is to
match the timing of gain or loss

                                       24
<PAGE>

recognition on the hedging derivative with the recognition of (i) the changes in
the fair value of the hedged asset or liability that are attributable to the
hedged risk, or (ii) the earnings effect of the hedged forecasted transaction.
For a derivative not designated as a hedging instrument, the gain or loss is
recognized in income in the period of change. SFAS No. 133 is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. Historically, we
have not entered into derivative contracts either to hedge existing risks or for
speculative purposes.

CERTAIN FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

We have a history of losses.

      Although we were formed almost 16 years ago in October 1983, and are now
close to realizing our commercial objectives, our business is subject to the
risks inherent in the establishment of a relatively new business enterprise in
the field of biopharmaceuticals. The likelihood of the success of our business
must be considered in the light of the problems, expenses, difficulties and
delays frequently encountered in connection with the development of new products
and the competitive and regulatory environment in which we are operating. Since
inception, we have only produced $28,381,000 in gross revenues and have had
cumulative losses of $83,830,000 (including a net loss of $11,862,000 in fiscal
1999). As a result our independent auditors have added an explanatory paragraph
to their report that these losses raise substantial doubt about our ability to
continue as a going concern. Although certain of our biopharmaceutical products
may be marketed in the fourth quarter of 2000, there can be no assurance that
marketing will begin when we anticipate, if at all, or that revenues from our
other products, including Kinetin, will rise to a level that will allow us to
operate profitably during the fiscal year ending December 31, 2000.

Our operating results may fluctuate significantly, and any failure to meet
financial expectations may disappoint securities analysts or investors and
result in a decline in our stock price, causing investor losses.

      Our operating results have fluctuated in the past and are likely to do so
in the future. These fluctuations could cause our stock price to decline. If
revenue declines in a quarter, whether due to a delay in recognizing expected
revenue or otherwise, our earnings will decline because many of our expenses are
relatively fixed in the short-term. In particular, research and development and
general and administrative expenses are not affected directly by variations in
revenue.

Due to fluctuations in our revenue and operating expenses, we believe that
period-to-period comparisons of our results of operations are not a good
indication of our future performance. It is possible that in some future quarter
or quarters, our operating results will be below the expectations of securities
analysts or investors. In that case, our stock price could fluctuate
significantly or decline.

We may need additional financing in order to continue our operations.

      Although we believe that we currently have sufficient equity, cash flow or
bank facilities to continue our operations during fiscal 2000, in the event that
we are unable to obtain further funding, or the costs of development and
operations prove greater than anticipated, we may be required to further curtail
our operations or seek alternative financing arrangements. Additional financing
may not be available to us on favorable terms or at all. If we have insufficient
funds or are unable to raise additional funds, we may be required to delay,
reduce or cease certain of our programs. This would materially and adversely
affect our business.

We may be unable to develop commercially successful products.

      Our product launches to date have generated limited revenues. We have a
variety of product candidates in various stages of development and will
undertake substantial additional research and development and pre clinical and
clinical testing of our products. These efforts may not result in the
development of any commercially successful products.

Some of our potential products are subject to the risks of failure inherent in
the development of new biopharmaceutical products including the risks that:

                                       25
<PAGE>

      o     a product candidate fails in pre clinical studies;

      o     a potential product is not shown to be safe and effective in
            clinical trials;

      o     we fail to obtain regulatory approval for the product;

      o     we fail to produce a product in commercial quantities at an
            acceptable cost; and

      o     a product does not gain market acceptance.

Future financings may result in the substantial dilution of shareholders'
interests and may result in future investors being granted rights superior to
those of existing shareholders. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations".

Continued research and development efforts are required or our products may be
rendered obsolete by other technological developments.

      We are engaged in a field characterized by extensive research efforts.
Despite our current access to leading expertise in the field, there remains a
risk that the research financed by us in the future could prove unproductive.
Furthermore, there can be no assurance that research and discoveries by other
companies will not render our programs superfluous or obsolete. This is true for
all companies who operate in the same field.

Competition in our industry is intense, and an inability to compete successfully
may harm our business.

      The biopharmaceutical, pharmaceutical and cosmeceutical industries are
highly competitive. Our business and research efforts compete with drug
discovery programs at biotechnology, drug delivery, biopharmaceutical and
pharmaceutical companies, as well as with internal drug discovery efforts of
pharmaceutical companies acting independently or in collaboration with other
companies. In addition, academic institutions, government agencies throughout
the world and public and private organizations conducting research may seek
intellectual property protection, discover competing products, or establish
collaborative arrangements in our area of research and development.


                                       26
<PAGE>


We face exposure to liability for our products.

      During recent years, lawsuits resulting in very substantial liability have
been filed against companies engaged in the manufacture of pharmaceutical and
other medical-related products or devices which have subsequently proved harmful
to human health. Many of these cases have exposed companies to liability long
after the products have been brought to market, even though, at the time of
their development, based on extensive research, there were no perceived risks of
injury. Thus, notwithstanding United States Food and Drug Administration ("FDA")
or other foreign governmental approval, there can be no assurance that we will
not be subject to liability from the use of our products. There is no assurance
that product liability coverage will be adequate to protect against future
claims. Management intends to have third parties manufacture and distribute
certain of our products and believes that our exposure to liability will thereby
be lessened. However, there can be no assurance that this result will be
achieved.

We rely on certain key suppliers in order to produce our products.

      We contract out manufacture of all of our products and purchase raw
materials from third-party suppliers. We recently established a dual supply
chain for Kinetin. Although we believe that other suppliers are available who
can produce similar materials and products, there can be no assurance that such
materials would be available to us on an immediate basis if needed, or at prices
similar to those now paid by us.

We face product liability risks of cosmetics.

      We are subject to the risk of product liability claims related to the use
of our products which are designed for application to human hair and skin. We
carry product liability insurance which management believes will be adequate to
cover risks associated with such use; however, there can be no assurance that
existing or future insurance coverage will be sufficient to cover any possible
product liability risks or that such insurance will continue to be available to
us on economically feasible terms.

If we are unable to effectively protect our intellectual property, we would be
unable to prevent third parties from using our technology, which could impair
our ability to compete in the market, and the cost of enforcing our proprietary
rights may be expensive and result in increased losses.

      Our success will depend in part on our ability to obtain and maintain
meaningful patent protection for our products, both in the United States and in
other countries, and our inability to do so could harm our competitive position.
We rely on our issued and pending patent applications in the United States and
in other countries to protect a large part of our intellectual property and our
competitive position. We cannot assure you that any of the currently pending or
future patent applications will issue as patents, or that any patents issued to
us will not be challenged, invalidated, held unenforceable or circumvented.
Further, we cannot assure you that our intellectual property rights will be
sufficiently broad to prevent third parties from producing competing products
similar in design to our products.

In addition to patent protection, we also rely on protection of trade secrets,
know-how and confidential and proprietary information. We generally enter into
confidentiality agreements with our employees, consultants and our collaborative
partners upon commencement of a relationship with us. However, we cannot assure
you that these agreements will provide meaningful protection against the
unauthorized use or disclosure of our trade secrets or other confidential
information or that adequate remedies would exist if unauthorized use or
disclosure were to occur. The exposure of our trade secrets and other
proprietary information would impair our competitive advantages and could have a
material adverse effect on our operating results, financial condition and future
growth prospects. Further, we cannot assure

                                       27
<PAGE>

you that others have not or will not independently develop substantially
equivalent know-how and technology.

Our commercial success also depends in part on avoiding the infringement of
other parties' patents or proprietary rights and the breach of any licenses that
may relate to our technologies and products. We are aware of several third-party
patents that may relate to our technology. We believe that we do not infringe
these patents but cannot assure you that we will not be found in the future to
infringe these or other patents or proprietary rights of third parties, either
with products we are currently developing or with new products that we may seek
to develop in the future. If third parties assert infringement claims against
us, we may be forced to enter into license arrangements with them. We cannot
assure you that we could enter into the required licenses on commercially
reasonably terms, if at all. The failure to obtain necessary licenses or to
implement alternative approaches may prevent us from commercializing products
under development and would impair our ability to be commercially competitive.

We may also become subject to interference proceedings conducted in the U.S.
Patent and Trademark Office to determine the priority of inventions. The defense
and prosecution, if necessary, of intellectual property suits, USPTO
interference proceedings and related legal and administrative proceedings will
result in substantial expense to us and significant diversion of effort by our
technical and management personnel. An adverse determination in litigation or
interference proceedings to which we may become a party could subject us to
significant liabilities to third parties, could put our patents at risk of being
invalidated or interpreted narrowly and could put our patent applications at
risk of not issuing.

Further, there is a risk that some of our confidential information could be
compromised during the discovery process of any litigation. During the course of
any lawsuit, there may be public announcements of the results of hearings,
motions and other interim proceedings or developments in the litigation. If
securities analysts or investors perceive these results to be negative, it could
have a substantial negative effect on the trading price of our stock.

Regulation by government agencies imposes significant costs and restrictions on
our business activities.

      The production and sale of pharmaceutical products is highly regulated.
Our ability and the ability of our partners to secure regulatory approval for
our products and to continue to satisfy regulatory requirements will determine
our future success. We may not receive required regulatory approvals for our
products or receive approvals in a timely manner. In particular, FDA and
comparable agencies in foreign countries, including the European Medicines
Evaluation Agency and the Medicine Control Agency ("MCA") in the U.K., must
approve human therapeutic and preventive products before they are marketed. This
approval process can involve lengthy and detailed laboratory and clinical
testing, sampling activities and other costly and time-consuming procedures.
While the time required to obtain approval varies, it can take several years.
Delays in obtaining regulatory approvals could adversely affect the marketing of
products and our ability to receive product revenues or royalties. We cannot
guarantee that we will be able to obtain the necessary approvals for clinical
testing or for the manufacturing and marketing of any products that we develop.

We are also subject to ongoing regulatory review. Discovery of previously
unknown problems with a product, manufacturer or facility or other violations of
regulatory requirements may result in:

      o     fines;

      o     suspensions of regulatory approvals;

      o     product recalls; and

      o     criminal prosecution.

The failure to obtain regulatory approvals, the restriction, suspension or
revocation of regulatory approvals or any other failure to comply with
regulatory requirements or changes in the regulatory framework could materially
and adversely

                                       28
<PAGE>

affect our business. For further discussion of regulations and potential
penalties, see "Business -- Government Regulation."

Professional guidelines could adversely affect our business.

      Private health organizations and science foundations may publish
recommendations for treatments, which affect various therapies, drugs or
procedures, including any products we might develop. These recommendations may
relate to:

      o     usage;

      o     dosage;

      o     method of administration; and

      o     use of other therapies simultaneously.

If patients and health care providers follow recommendations or guidelines that
result in decreased use of our products, our business could be materially and
adversely affected.

The price of our Ordinary shares is volatile.

      The market price of our Ordinary shares, like that of other biotechnology
companies, has fluctuated significantly. Factors that could cause the combined
company's stock price to fluctuate in the future may include:

      o     announcements by us or our competitors of clinical trial results and
            other product developments;

      o     adverse developments in the protection of intellectual property or
            other legal matters;

      o     announcements in the scientific and research community or by other
            biotechnology companies;

      o     regulatory changes that affect our products;

      o     fluctuations in our operating results; and

      o     changes in third-party reimbursement policies or in medical
            practices.

Third-party reimbursement and health care cost containment initiatives may
constrain our future revenues.

      Our ability to successfully market any product we develop, and
particularly with respect to our Invicorp(TM) product, will depend in part on
the level of reimbursement that government health administration authorities,
private health coverage insurers and other organizations provide for the cost of
our products and related treatments. We may not be able to sell our products
profitably if reimbursement is unavailable or limited in scope. Third-party
payers may not reimburse patients for newly approved health care products such
as those that we are developing. Increasingly, third-party payers are attempting
to contain health care costs in ways that are likely to impact our development
of products including:

      o     challenging the prices charged for health care products;

      o     limiting both coverage and the amount of reimbursement for new
            therapeutic products;

      o     denying or limiting coverage for products that are approved by the
            regulatory agencies but are considered experimental or
            investigational by third-party payers; and

      o     refusing to provide coverage when an approved product is used in a
            way that has not received regulatory marketing approval.

We face product liability risks and may not be able to obtain adequate insurance

      The testing, marketing and sale of our products involve significant
product liability risks. We may be held liable for damages for product failures
or adverse reactions resulting from the use of our products. This liability
could have a material adverse effect on us. Although we maintain product
liability insurance, this insurance may not provide adequate coverage against
product liability claims. Furthermore, in the future, we may not be able to
obtain insurance on acceptable

                                       29
<PAGE>

terms and any insurance we do obtain may not provide adequate coverage against
any asserted claims.

United States judgments may not be enforceable against us.

      Judgments of United States courts, including those predicated on the civil
liability provisions of the federal securities laws of the United States, may
not be enforceable in English courts. As a result, stockholders who obtain a
judgment against Senetek in the United States may not be able to require Senetek
to pay the amount of the judgment.

ITEM 7A--QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our primary market risks include fluctuations in interest rates, variability in
interest rate spread relationships (i.e., Prime to LIBOR spreads) and exchange
rate variability.

We believe that fluctuations in interest rates and currency exchange rates in
the near term would not materially affect our consolidated operating results,
financial position or cash flows as we have limited risks related to interest
rate and currency exchange rate fluctuations.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

Compensation Principles

The Company's compensation policy is administered by three Directors acting as
the Compensation Committee and is designed to complement the Company's short and
long term business strategy for attracting and retaining key executives critical
to the Company's success.

At its present stage of development, the Company's corporate performance cannot
be gauged nor can compensation be measured in terms of profitability as it has
focused on developing its products, obtaining the necessary regulatory
approvals, attracting sufficient equity finance for this purpose and endeavoring
to negotiate licensing agreements for the development and marketing of its
products.

Currently the Company and its two subsidiaries Senetek Drug Delivery
Technologies Inc. and Carme Cosmeceutical Sciences, Inc. have 13 employees, 11
in the United States (including one executive Director), and 2 in the United
Kingdom. Given its personnel structure and the Company's formative stage of
development, it had not, in the past, been practicable for the Company to set up
a detailed and integrated compensation philosophy for its executives, nor to
specify levels of seniority, areas of responsibility, performance criteria and
profitability-related awards.

Executive Compensation

Typically, executives have been awarded fixed term employment agreements. In the
cases of Mr. Massino and Dr. Van Lear for a fixed period to December 31, 2003
and April 14, 2002 respectively.

The compensation of executive officers, including the Chief Executive Officer,
has been determined by a consideration of the compensation paid to officers in
companies in a similar position to Senetek. In certain cases the agreements
provide for consideration by the Board of a bonus but there is otherwise no
provision for a review of compensation during the fixed term of the agreements.
A bonus to Mr. Massino of $50,000 was granted in 1999.

Additionally, stock options entitling the grantee to purchase Ordinary shares in
the Company may be issuable at such times when the Board considers that certain
critical stages in the Company's product development or funding requirements
have been achieved.

Employee Option Plan

The Company's shareholders approved the adoption of a Share Option Scheme for
Employees (the No. 1 Plan) and a Share Option Scheme for Non-Executive Directors
(the No. 2 Plan) at a Special Meeting of shareholders on December 20, 1985. At
the Annual Meeting of shareholders on May 23, 1997, the total number of options
available for issuance under the No. 1 and No. 2 Plans was increased to
6,000,000 and 4,000,000 respectively. Options under the No. 1 and No. 2 Plans
may not be granted at an exercise price lower than the market price for the
Company's shares 21 days prior to the date of grant.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To Board of Directors and
Stockholders of Senetek PLC

We have audited the accompanying consolidated balance sheets of Senetek PLC and
its subsidiaries as of December 31, 1999 and 1998, and the related statements of
operations, stockholders' equity (deficit) and cash flows for each of the two
years in the period ended December 31, 1999. We have also audited Schedule II -
Valuation and Qualifying Accounts (the Schedule). These financial statements and
the Schedule are the responsibility of Senetek PLC's management. Our
responsibility is to express an opinion on these consolidated financial
statements and the Schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Senetek PLC
at December 31,1999 and 1998, and the results of its operations and their cash
flows for each of the two years in the period ended December 31,1999 in
conformity with generally accepted accounting principles.

Also, in our opinion, the Schedule presents fairly in all material respects the
information set forth therein.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company has a stockholders' deficit, negative working
capital and has suffered recurring losses from its operations. Its ability to
continue research activities to a stage where it has a product available for
sale is dependent upon securing additional sources of financing. These
conditions raise substantial doubt about the Company's ability to continue as a
going concern. Management's plans in regard to this matter are also described in
Note 2. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Shareholders of Senetek PLC

In our opinion, the consolidated statements of operations, of cash flows and of
stockholders' equity for the year ended December 31, 1997 (appearing on pages
F-2 through F-26 of the Senetek PLC Form 10-K Annual Report for the year ended
December 31, 1999) present fairly, in all material respects, the results of
operations and cash flows of Senetek PLC and its subsidiaries for the year ended
December 31, 1997, in conformity with generally accepted accounting principles.
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 audit. We conducted our audit of these statements in accordance with
generally accepted auditing standards, which require that we plan and perform
the audit to obtain reasonable reassurance 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for the opinion expressed
above. We have not audited the consolidated financial statements of Senetek PLC
for any period subsequent to December 31, 1997.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The Company has suffered recurring
losses from its pharmaceutical operations and, as described in Note 2 (b), its
ability to continue research activities to a stage where it has a product able
to be commercialised is dependent upon securing additional sources of financing,
which raises substantial doubt about the Company's ability to continue as a
going concern. Management's plans in regard to this matter are also described in
Note 2 (b). The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

                                   SENETEK PLC

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1.   ACTIVITIES

Senetek PLC ("the Company") is a science-driven biotechnology company that
develops, manufactures and markets proprietary products for the enhancement of
quality of life, primarily products for the diagnosis and treatment of
aging-related healthcare problems. Recently, the company has decided to focus on
two business sectors, biopharmaceuticals, in particular therapeutic agents for
erectile dysfunction and female sexual dysfunction, and proprietary skincare
technologies. In connection with product development activities, we sponsor
research in the life sciences and biotechnology fields.

The Company also sells monoclonal antibodies purchased from outside suppliers
and derived from sponsored research into diagnostic procedures for Alzheimer's
disease and other cell lines to the scientific community for research purposes.

Senetek PLC is a public limited company that was registered in England in 1983
(registration number 1759068). We have two wholly owned subsidiaries, Senetek
Drug Delivery Technologies Inc. ("SDDT") and Carme Cosmeceutical Sciences Inc.
("CCSI") both of which are Delaware corporations.

Subsidiary Undertakings

SDDT (formerly named MEIS Corporation) was incorporated in the State of Delaware
in December 1993. Its main activity is the development, production and
distribution of the auto-injector systems for use with the Company's Erectile
Dysfunction compound.

CCSI (formerly named Carme International, Inc.) was incorporated in the State of
Delaware in June 1995. Its main activity is the supply of skincare products to
various segments of the skincare market.

2.      PRINCIPAL ACCOUNTING POLICIES

(a)     Basis of Consolidation

The consolidated financial statements incorporate the accounts of Senetek PLC
and its wholly owned subsidiaries, CCSI and SDDT. All significant intercompany
balances and transactions have been eliminated in consolidation. The accounts
have been prepared in accordance with U.S. generally accepted accounting
principles (U.S. GAAP). Certain prior year balances have been re-classified in
order to conform to current year presentation.

(b)     Going concern uncertainty

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The Company's ability to continue as a
going concern may depend on its ability to obtain financing sufficient to
support its operations and business development plans.

The financial statements reflect a loss for the year ended December 31, 1999 of
$11,862,000, which, when taken with the previous years results, results in an
accumulated deficit of $83,830,000 at December 31, 1999. Cash and cash
equivalents increased by $1,032,000 during fiscal 1999, from $808,000 to
$1,840,000. The losses raise a substantial doubt as to the Company's ability to
continue as a going concern. The Company has been able to fund this deficit from
existing resources and through the sale of equity securities and issuance of
debt. Management has taken steps to reduce the amount of cash used by
operations, including reducing staffing levels. However, the Company's
operations are not likely to provide sufficient internally generated cash flows
to meet its projected requirements in the short term and to meet the cost of
developing the Company's pharmaceutical products. Management is also discussing
the possibility of entering into licensing agreements with several
pharmaceutical companies.

Management is engaged in continuing efforts to obtain sufficient financing to
fund its operations for the foreseeable future however there can be no assurance
given that the Company will be able to obtain the necessary financing.

(c)      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 and disclosures;
contingent assets and liabilities at the date of the financial statements; and,
the reported amounts of revenue and expenses during the reporting period.
Accordingly, actual results could differ from those estimates. It is at least
reasonably possible that the significant estimates used will change within a
year.

(d)     Cash and Cash Equivalents

For the purposes of the statement of cash flows and balance sheet, the Company
considers any highly liquid investments purchased with an original maturity of
three months or less to be cash equivalents.

(e)     Revenues

Revenues are recognized at the time of shipment (or time of rendering services)
and are stated at the net invoiced value of goods and services supplied to
customers after deduction of sales and value added tax where applicable. License
fees received on the licensing out of distribution rights for our Kinetin
products are treated as deferred income and are recognized as revenues earned
during the contract period.


                                      F-9
<PAGE>

(f)     Inventories

Inventories, constituting finished goods, raw materials and work-in-progress are
stated at the lower of cost or market value. Cost is determined using the
average costing method.

(g)     Property and Equipment

Property and equipment are stated at cost less accumulated depreciation.
Depreciation is calculated on a straight line basis using the following
estimated useful lives:

Office Furniture, Fixtures and Equipment   3 to 15 years

Laboratory equipment                             5 years

Leasehold Improvements                          10 years

Leasehold improvements are amortized over the estimated useful lives of the
assets or the related lease term, whichever is the shorter.

(h)     Intangible Assets

Goodwill is being amortized on the straight line method over 15 years. Goodwill
included in the consolidated financial statements relates to the Company's
acquisition on September 26, 1995 of certain assets of CCSI.

(i)     Impairment of Long-Lived Assets

In accordance with Statement of Financial Accounting Standards ("SFAS") No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long Lived Assets to
Be Disposed Of", the Company reviews the carrying value of its property and
equipment and intangible assets for impairment in value whenever events or
changes in circumstances indicate that the carrying amount of assets may not be
recoverable.

(j)     Research and Development

Expenditures on research and development are expensed as incurred.

(k)     Foreign Exchange

The Company follows currency translation principles established by SFAS No. 52.
All assets and liabilities in the balance sheets of foreign branches and
subsidiaries whose functional currency is other than U.S. dollars are translated
at period-end exchange rates. All income and expenditure items in the profit and
loss account of foreign branches and subsidiaries whose functional currency is
other than U.S. dollars are translated at average monthly exchange rates.
Translation gains and losses arising from the translation of the financial
statements of foreign branches and subsidiaries whose functional currency is
other than the U.S. dollar are not included in determining net income but are
accumulated in a separate component of stockholders' equity <deficit>. Foreign
currency transaction gains and losses are included in the determination of net
income in the period in which they occur. The functional currency of the
Company's United Kingdom operation is the Pound Sterling.

(l)     Calculation of the Number of Shares in Issue and Net Loss per Share

Earnings per share were computed under the provisions of Statement of Financial
Accounting Standards No.128, Earnings per Share. The following is a
reconciliation of the numerators and denominators of basic and fully diluted
earnings per share computation.

</TABLE>

Options and warrants to purchase 14,277,673, 7,135,315 and 6,238,971 Ordinary
shares were outstanding at December 31, 1999, 1998 and 1997 respectively, but
were not included in the computation of diluted loss per Ordinary share
outstanding because their effect would have been antidilutive.

(m)     Financial Instruments

The carrying value of cash, receivables and current liabilities, approximate
fair value due to the short term nature of these items. The fair value of the
Company's long term notes payable is approximately $6,000,000. The carrying
value of these notes at December 31, 1999 is $7,101,000. Fair value is the
amount at which the instrument could be exchanged in a current transaction
between willing parties, other than in a forced sale or liquidation.

(n)     Income Taxes

The Company's recognizes deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns. Accordingly, deferred tax liabilities and assets are
determined based on the difference between financial statements and tax basis of
assets and liabilities using enacted rules in effect for the year in which
differences are expected to reverse. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date.

A valuation allowance is established to reduce the deferred tax assets when
management determines it is more likely than not that the related tax benefits
will not be realized.

(o)    Recent Accounting Pronouncements

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 requires companies to
recognize all derivative contracts as either assets or liabilities in the
balance sheet and to measure them at fair value. If certain conditions are met,
a derivative may be specifically designated as a hedge, the object of which is
to match the timing of gain or loss recognition on the hedging derivative with
the recognition of (i) the changes in the fair value of the hedged asset or
liability that are attributable to the hedged risk, or (ii) the earnings effect
of the hedged forecasted transaction. For a derivative not designated as a
hedging instrument, the gain or loss is recognized in income in the period of
change. SFAS No. 133 as amended by SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities - Deferral of The Effective Date of FASB
Statement No. 133", is effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. Historically, the Company has not entered into
derivative contracts either to hedge existing risks or for speculative purposes.
Accordingly, the Company does not expect adoption of this standard to effect its
financial statements.

(p)      Reclassification

Certain assets and expenses for 1998 and 1997 have been reclassified to conform
to current year presentation.

3.      CONCENTRATION OF CREDIT RISK

Three customers in the Company's skincare sector account for approximately 56%,
12% and 18% of the Company's revenues in 1999. The same customers account for
22%, 16% and 38% respectively of the Company's net trade receivables at December
31, 1999. There is a therefore a significant concentration of credit risk with
respect to these customers.

4.      NON TRADE RECEIVABLES

Non trade receivables of $188,000 (1998 $603,000) principally comprise amounts
receivable under two promissory notes relating to the April 13, 1999 settlement
agreement.

5.      INVENTORY

Inventory at cost comprises the following:

                                       December 31, 1999    December 31, 1998

In December 1999, the Company abandoned certain fixed assets. As a result of
this abandonment, the Company recorded an impairment loss of $1,522,000. The
assets abandoned comprised of assets in progress associated with the Reliaject
development and computers and office equipment. The pharmaceutical and skincare
business segments were written down by $1,407,000 and $115,000 respectively.

Under the terms of an agreement dated December 13, 1999 the Company issued to a
capital equipment supplier a Convertible Promissory Note for $700,000 in
exchange for an equivalent amount recorded in accounts payable. The Note can be
converted into Senetek 5p Ordinary shares at a conversion rate of $2.00 per
share after August 1, 2000 for a period of 31 days from that date. If conversion
is not elected, then the Note is repayable in cash.

$7,389,000 Investment Notes issued on April 14, 1999. See Note 11.

Customer advances relates to monies received to finance the purchase of raw
material inventories for products supplied.

10.      LINE OF CREDIT

On July 8, 1998 the Company received $5,940,000 ($6,600,000 less a 10% fee)
under the terms of a $10 million Credit Agreement with a third party. This line
of credit is non interest bearing and fell due in April 2000. In connection with
this line of credit 1,885,714 warrants at an exercise price of $3.50 and 377,150
warrants at an exercise price of $6 were granted. The fair value of these
warrants, calculated using the Black Scholes model was calculated at $3,936,000.
The fair value of these warrants was being amortized, using the interest rate
method, over the term of the credit agreement. (See Note 14).

In September 1998, the $3.50 warrants were exercised, without payment, and
1,885,714 Ordinary shares were issued by the Company to extinguish this line of
credit. Subsequent to that date the Company entered into discussions with the
third party involving a dispute over the actual exercise price of the warrants
and whether any amounts remained outstanding under the original $6.6 million
loan agreement.

Pursuant to these discussions, the Company agreed to reduce the exercise price
of the warrants from $3.5 to $2 and sell an additional 220,000 shares at $2 per
share. As a result of these transactions, approximately $4.2 million of the
original $6.6 million credit agreement was exchanged for approximately 2,105,000
shares of common stock. As a result of the Company reducing the exercise price
of the warrants, the Company recognized a debt modification expense totaling
$2,389,000. Refer to Note 11 for discussion of 1999 activity.

11.  NOTES PAYABLES AND SETTLEMENT EXPENSE

In April 1999, the Company received $4,751,000 (net of $249,000 in expenses) in
cash and refinanced the balance owed of $2,389,000 under a 1998 Credit
Agreement, in exchange for two new notes currently bearing interest at 9% per
annum and maturing in April 2002. The notes require semi annual payment of
interest only until maturity and are secured by all of the Company's assets.
Interest may be paid in cash or Ordinary shares that have been registered with
the SEC.


                                      F-15
<PAGE>

The Company issued Series A warrants to purchase an aggregate of 738,857
Ordinary shares at $1.50 per share, which have been adjusted to $1.20 according
to certain terms of the agreement. The Series A warrants expire after five
years. Series B and C warrants to purchase approximately 3.3 million and 1.2
million Ordinary shares at $1.50 and $2 per share were issued in connection with
the Agreement but are only exercisable to the extent the outstanding principal
balance of $7,389,000 is not repaid in cash. The Series B and C warrants expire
in ten years.

The fair value of 500,000 of the Series A warrants and all of the Series B
warrants was determined to be $3.1 million using the Black Scholes model. The
fair value of these warrants will be amortized over the life of the new notes as
such warrants, under the terms of the financing agreement, were issued in
connection with the $5.0 million new financing. On the other hand, the $1.0
million fair value of the remaining 238,857 Series A warrants and all of the
3,333,333 Series C warrants was included in the loss on extinguishment of debt
discussed below because these warrants were issued to refinance existing debt
under the terms of the April 1999 financing agreement.

As the outstanding borrowings under the 1998 Credit Agreement were refinanced by
notes with substantially different terms as defined by EITF 96-19, Debtors
Accounting for a Modification or Extinguishment of Debt Instruments, (EITF
96-19), the Company is required to recognize the difference between the fair
value of the new notes issued to refinance the old debt and the carrying value
of the old debt net of unamoritized issuance costs as a loss on the
extinguishment of debt. During the year ended December 31,1999, the Company
recognized a $1.7 million loss on the extinguishment of debt.

Also, in April 1999 the Company entered into a settlement agreement to resolve
the terms of various transactions that had been entered into by the
previous management of the Company. The settlement terms involve the issue of
2,300,000 Series A warrants and 625,000 new Ordinary shares. Accordingly the
Company has recorded $2.7 million of expense in the second quarter of 1999
related to the settlement terms. Included in the $2.7 million settlement expense
is the fair value of the 625,000 Ordinary shares issued in 1999.

12.     STOCK OPTIONS PLANS

        (a)     On October 8, 1993, 4,550,000 options, representing the total
                number of options available for grant at that time were
                registered with the Securities and Exchange Commission on Form
                S-8.

                In December 1985, the Company adopted a share option plan (the
                "No. 1 Plan") for employees. Under the Plan, options to purchase
                Ordinary shares are granted by the Board of Directors, subject
                to the exercise price of the option being not less than the
                market value of an Ordinary share twenty-one days prior to the
                grant date. After the first twelve months following the date of
                the grant, options are exercisable at the rate of 25 percent,
                for each full year of employment. In the event the optionee's
                employment is terminated; the option may not be exercised unless
                the Board of Directors so permits. The options expire seven
                years from the date of the grant. On May 16, 1997 shareholders
                approved the extension of the Plan until December 1, 2005 and an
                increase in the number of shares available for grant to
                6,000,000.

        (b)     In May 1987 the Company adopted a share option plan ("the No. 2
                Plan") for non-Executive Directors and Consultants. Under the
                No. 2 Plan, options to purchase Ordinary shares are granted by
                the Board of Directors, subject to the exercise price being not
                less than the market value of an Ordinary share 21 days prior to
                the grant date. Options granted under this plan are exercisable
                in their entirety one year after the date of grant. In the event
                the optionee ceases to be a non-executive Director or
                consultant, the option may not be exercised unless the Board of
                Directors so permits. The options expire seven years from the
                date of grant. On May 16, 1997 shareholders approved an
                extension of the Plan until December 1, 2005 and an increase in
                the number of shares available for grant to 4,000,000.

13.     STOCK COMPENSATION EXPENSE

Under U.S. GAAP, the Company applies Accounting Principle Board Opinion No. 25,
"Accounting for Stock Issues to Employees" and related interpretations in
accounting for its option plans. 1999 $(699,000) (1998: $1,664,000; 1997:
$3,048,000) of expense has been recognized for stock based employee compensation
in accordance with APB 25. These expense amounts relate to options issued
outside the No. 1 Plan. Had compensation expense been determined based upon the
fair value at the grant date for awards as an alternate provided by SFAS 123,
"Accounting for Stock-Based Compensation", the Company's net loss and loss per
share would be $13,641,000 and $0.24 per share respectively in 1998, $24,394,000
and $0.45 per share respectively in 1998, and $16,489,000 and $0.34 per share,
respectively in 1997. These amounts are for disclosure purposes only and may not
be representative of future calculations, since the estimated fair value of
stock options is amortized to expense over the vesting period, and additional
options may be granted in future years.

The fair value of the options granted are estimated using the Black Scholes
option pricing model with the following assumptions:

Dividend yield of nil, volatility of 53% (1998 - 76% and 1997 - 94%), risk-free
investment rate of 6.1% (1998 - 6.1%, 1997 - 6.1%), and an expected life of 6
years.

The average fair values of the options granted for each Ordinary share American
Depositary Receipt during 1999, 1998 and 1997 are estimated at:

During 1999, the Company recognized $776,000 (1998 $868,000; 1997: $840,000) of
general and administrative expense relating to all stock options awarded to
non-employees and consultants in exchange for services based upon the fair value
of the awards at the grant date which were estimated using the Black Scholes
option pricing model with the following assumptions.

Dividend yield of nil, (1997:nil) volatility of 53%, (1998:76%, 1997:85%) risk
free investment rate of (1998:6.1%, 1997:6.3%) and an expected life of 4 years
(1998: 4 years, 1997: 4 years).

14.     STOCKHOLDERS' EQUITY

During the year ended December 31, 1999, the outstanding Ordinary shares of the
Company increased by 932,661 to 58,148,517. Ordinary shares in the amount of
625,000 were issued in August 1999 to Windsor Capital and Wallington Investments
according to the terms of the Settlement Agreement dated April 13, 1999. The
exercise of 116,661 Employee stock options into an equivalent number of Ordinary
shares took place in the first quarter of 1999. In addition Ordinary shares

16.     TAXATION

The Company is incorporated in England with two U.S. subsidiaries. The Company
is subject to United Kingdom corporation tax on a worldwide basis with relief
for foreign taxes in cases where double taxation relief agreements have been
established. The Company will be liable for United States tax (including state
taxes) through the U.S. subsidiaries.

No income tax charges/(credits) have been reflected in the Consolidated
Statement of Operations due to the net operating losses in the year which
substantially accounts for the deferred tax asset.


                                      F-22

Deferred tax assets are comprised of the following:

The difference between the effective tax rate and statutory tax rate is
primarily due to the $4,100,000 increase in the valuation allowance.

Provisional tax losses available to the Company in the United Kingdom are
estimated to be approximately $37,100,000 at the end of fiscal year 1999. The
deferred tax asset value of these losses is approximately $11,700,000 but no
benefit has been recognized in the financial statements as the benefit is offset
by an equal valuation allowance as it is more likely than not that the Company
will not generate taxable income in the foreseeable future to utilize the
deferred tax asset.

Federal provisional tax losses available to the Company in the U.S. are
estimated to be approximately $30,800,000 at the end of fiscal year 1999. The
deferred tax asset value of these losses is approximately $10,500,000 but no
benefit has been recognized in the financial statements as the benefit is offset
by an equal valuation allowance as it is more likely than not that the Company
will not generate taxable income in the foreseeable future to utilize the
deferred tax asset. Federal net operating losses expire at varying dates from
2002 through 2018. California net operating losses are estimated to be
approximately $11,900,000. The resulting deferred tax asset from California net
operating losses is approximately $700,000. A 100% provision has also been
established for this asset. California net operating losses expire at varying
dates from 2001 through 2004.

17.     INDUSTRY AND GEOGRAPHIC AREA SEGMENT

In June 1997, SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information," was issued effective for fiscal years ending after
December 15, 1998. The Company's reportable segments are strategic business
units that offer different products and services. They are managed separately
because each business requires different technology and marketing strategies.
The Company has two reportable segments: Pharmaceutical operations and skincare
operations. The Pharmaceutical operations comprise Senetek PLC and SDDT and
include biopharmaceuticals, drug development, drug delivery development and the
sale of monoclonal antibodies. The skincare operation comprises CCSI and
includes the distribution of primarily Kinetin based skin care products to a
number of markets in North America. The accounting policies of the segments are
the same as those described in the summary of significant accounting policies.
All intersegment sales prices are market based. The Company evaluates
performance based on operating results of the respective business units.

                                  2000                             $406

                Rent expense was approximately $468,000, $575,000 and $676,000
                in 1999, 1998 and 1997 respectively.

        (c)     Litigation

                Various claims, suits and complaints, such as those involving
                patents, commercial transactions and employee matters, arise in
                the ordinary course of the Company's business. In the opinion of
                management, all such pending matters are without merit or
                involve such amounts, which would not have a material adverse
                effect on the Company's consolidated financial position,
                liquidity, cashflows or results of operations for any year.

        (d)     Contingencies

                The Company has disputed a third quarter 1999 invoice from a
                supplier, in the amount of $350,000 for a supply of vasoactive
                intestinal polypeptide under a supply agreement dated April
                2,1998. Management is of the opinion that an accrual for this
                invoice is not necessary because loss is not probable. In the
                opinion of management the invoice was outside the scope of
                contractual obligations between the Company and the supplier and
                the products were neither ordered nor received by Senetek.

        (e)     Employment Contracts

                The Company has entered into employment agreements with two of
                its officers, Frank Massino (CEO) and George Van Lear (COO). The
                agreements are for a three year period, but automatically renew
                unless specifically terminated by the Company or the employee.
                If the employment agreements are terminated by the Company, the
                officers will be entitled to an additional three years of
                compensation. Annual compensation under the employment
                agreements are $250,000 and $200,000 for Mr. Massino and Dr. Van
                Lear respectively. In addition the agreements provide for
                incentive and additional compensation under certain
                circumstances.
