     The  success  of the  Company is very much  dependent  on the  talents  and
commitment  of a core  management  team.  The  loss of the  services  of any key
management figure such as Sinovac's President Dr. Yin or the CEO, Professor Pan,
of Sinovac's 51% owned  subsidiary,  Sinovac Biotech Co. Ltd.,  could negatively
impact the Company's progress.

     Regulatory Environment
     ----------------------

     There can be no assurance  that all of the clinical  trials  pertaining  to
several  of  Sinovac's  in-development  vaccines  will be  completed  within the
anticipated time frame. Furthermore,  such trials may be delayed or suspended at
any time by regulatory  agencies if unforeseen health risks become an issue with
the participants of clinical trials.

     Proprietary Technology
     ----------------------

     The Company's  success will largely depend on its ability to maintain trade
secret protection,  particularly with regards to avoiding patent infringement by
other parties.  The Company must also ensure that it operates without infringing
on the proprietary rights of other immunology companies.

     Potential Product Liability
     ---------------------------

     Human vaccine  products  involve an inherent risk of product  liability and
associated adverse publicity.  A product liability claim or a product withdrawal
could have a material adverse effect on the Company.

     Political Risk
     --------------

     The value of the Company's  assets and business  ventures in China could be
adversely  impacted by any reversal of China's  longstanding  policy of economic
reforms.  For  instance,  a change  in  leadership  or social  disruption  could
jeopardize Sinovac's business endeavors in this communist regime.

     Cash Flow and Requirements for New Capital
     ------------------------------------------

     As with most  companies  in the  biotechnology/biopharmaceutical  industry,
Sinovac will need to raise  further  funds from the capital  markets to continue
the development and  commercialization of its product pipeline.  The Company has
adequate near-term cash requirements, however, the Company may need to undertake
significant  future financings to complete clinical trials for its SARS vaccine,
as well as to facilitate the large-scale commercial rollout of its other vaccine
products.  The currently strong biotechnology  financing  environment  mitigates
these financial risks.  However,  the prospect of meeting these future financial
requirements in the capital markets cannot be guaranteed.






                                        5




     Reliance on Partnerships for Promotion and Marketing of Products
     ----------------------------------------------------------------

     The Company's first international licensing/marketing partner is the Korean
immunology  company,  Innopath  International  Inc. The signing of other similar
partnerships, particularly with large European and North American pharmaceutical
companies,  is key to  achieving  meaningful  market  share in  these  lucrative
marketplaces.  Indeed, the successful monetization of Sinovac's product pipeline
will depend to an extent on how proactive these future partners are in promoting
and marketing Sinovac's proprietary vaccine products.

     Risk of "Penny Stock"
     ---------------------

     The Company's  common shares may be deemed to be "penny stock" as that term
is defined in Regulation  Section  "240.3a51-1"  of the  Securities and Exchange
Commission (the "SEC").  Penny stocks are stocks:  (a) with a price of less than
U.S.  $5.00  per  share;  (b) that are not  traded  on a  "recognized"  national
exchange;  (c) whose  prices are not quoted on the  NASDAQ  automated  quotation
system (NASDAQ - where listed stocks must still meet requirement (a) above);  or
(d) in issuers with net  tangible  assets of less than U.S.  $2,000,000  (if the
issuer  has been in  continuous  operation  for at least  three  years)  or U.S.
$5,000,000  (if in  continuous  operation  for less than three  years),  or with
average revenues of less than U.S. $6,000,000 for the last three years.

     Section  "15(g)" of the United States  Securities  Exchange Act of 1934, as
amended, and Regulation Section  "240.15g(c)2" of the SEC require broker dealers
dealing  in  penny  stocks  to  provide  potential  investors  with  a  document
disclosing  the risks of penny stocks and to obtain a manually  signed and dated
written  receipt of the document  before  effecting any  transaction  in a penny
stock for the investor's  account.  Potential  investors in the Company's common
shares are urged to obtain and read such disclosure  carefully before purchasing
any common shares that are deemed to be "penny stock.".

     Moreover, Regulation Section "240.15g-9" of the SEC requires broker dealers
in penny stocks to approve the account of any investor for  transactions in such
stocks before selling any penny stock to that investor.  This procedure requires
the broker dealer to: (a) obtain from the investor information concerning his or
her financial situation,  investment experience and investment  objectives;  (b)
reasonably  determine,  based on that  information,  that  transactions in penny
stocks are  suitable  for the  investor  and that the  investor  has  sufficient
knowledge and experience as to be reasonably  capable of evaluating the risks of
penny stock  transactions;  (c) provide the  investor  with a written  statement
setting  forth the basis on which the broker  dealer made the  determination  in
(ii) above;  and (d) receive a signed and dated copy of such  statement from the
investor  confirming  that  it  accurately  reflects  the  investor's  financial
situation,  investment  experience and investment  objectives.  Compliance  with
these  requirements  may make it more  difficult  for investors in the Company's
common  shares to resell  their common  shares to third  parties or to otherwise
dispose of them.

                                        7




B.   Business Overview
     -----------------

     The Company  specializes in the research,  development,  commercialization,
and sales of human  vaccines for  infectious  illnesses  such as Hepatitis A and
Hepatitis B,  influenza and "SARS".  The Company is one of the leading  emerging
biotechnology  companies in China.  Working  closely with Chinese  public health
officials, the Company focuses on manufacturing and marketing human-vaccines and
related products, and currently markets its vaccine for Hepatitis A. The Company
is the first and  currently  the only  company in the world to have been granted
permission to begin clinical trials for a vaccine to prevent SARS.

Cash Resources and Liquidity
- ----------------------------

     As of May 31, 2004, the Company had approximately  US$2,608,368 in cash and
a positive working capital position of approximately US$3,153,873.

Stated Business Objectives
- --------------------------

     The overall strategic mission of the Company is to become a world leader in
the innovation, development and manufacturing of vaccines for historical viruses
such as hepatitis,  influenza,  and for fast-emerging viruses such as "SARS" and
Avian Influenza (a.k.a. "bird flu").

     The Company believes that it is possible and financially  viable to provide
safe, efficient vaccines to all countries regardless of wealth.  Through careful
financial management,  low production costs and modern,  innovative  techniques,
the  Company   intends  to  continue  to  produce  high  quality   vaccines  and
successfully  service market sectors that many pharmaceutical  giants are unable
to service.

     The following  represents the Company's  short-term  objectives  (i.e., the
next 12 months) for research, development and marketing.

     Objectives
     ----------

2004:
- -----

- - Expand domestic marketing for the company's Hepatitis A vaccine, "Healive;"
- - Expand Healive's regional marketing into Southeast Asian countries;
- - Gain government (SFDA) licensing  approval of the Company's Combined Hepatitis
  A&B  vaccine,  "Bilive"  during  Q3  or  Q4 of  2004.  Once approved, initiate
  marketing plan immediately; and
- - The Company  anticipates  signing agreements for third world marketplaces that
  are not currently serviced by the Company, or by Innopath International Inc.






                                        8




2005:
- -----

- - In the event of a global SARS outbreak,  nations worldwide would need to adopt
  the Company's in-development vaccine as a first line of defense;
- - Develop  strategic  alliances with established  pharmaceutical  companies that
  have significant sales and distribution channels;
- - The Company expects to gain federal-government  approval and commercialize its
  proprietary influenza vaccine by 2005, with the additional  goal of  targeting
  the majority of other developing Southeast  Asian markets within the next five
  years; and
- - The Company  expects to register  and  license its  Hepatitis A (Healive)  and
  Combined Hepatitis A&B (Bilive) vaccines in at least 34 countries by 2009.

     Marketing Objectives
     --------------------

     The  Company's  marketing  strategy is based on two  capabilities,  organic
growth, augmented as necessary,  and strategically beneficial acquisitions.  The
Company will combine and organize these capabilities into a bifurcated marketing
plan  (regional  and  global).  Each branch of this plan is intended to focus on
public and private sectors in order to achieve sales and growth objectives.  The
public sector  consists of government and  non-government  organization  ("NGO")
programs,  and the  private  sector  consists  of  independent/  private  health
insurance companies and private citizens.

     First the Company intends to target progressive  geographic  expansion with
its family of vaccines that target historically devastating viruses. The Company
is building a sales  organization in the Chinese domestic  market.  Concurrently
with its domestic  marketing  plan, the Company is  establishing a marketing and
sales presence in South East Asia and other developing countries.

     The second  prong of the  Company's  marketing  strategy is  contingent  on
creating a blockbuster  vaccine for defeating  emerging  viruses such as SARS or
the Avian Flu. In such case,  the first to market  advantage  opens the door for
sales to the international  market.  In such a scenario,  the Company intends to
enter the international  market,  with a worldwide sales network of professional
sales teams, well-organized selling channels, a sound customer-credit management
scheme, and an efficient logistics system.

     The Global Viral Environment
     ----------------------------

          Global Viral Background
          -----------------------

     Although  `virus'  and  `vaccine'  are common  terms  that most  people are
familiar with, several variations of both exist. To ensure a clear understanding
of the Company's  business and market sector some  definitions and  explanations
are provided.

Viruses:
- --------

     A virus is best  described  as an  infectious  agent  characterized  by its
inability  to reproduce  outside of a living host cell.  Viruses may subvert the
host cells' normal functions,  causing the cell to behave in a manner determined
by the virus.

     When a virus  attacks  the body  for the  first  time,  the  immune  system
attempts  to  identify  and produce  antibodies  to fight the virus.  The immune
system's  success depends on whether it has encountered the virus before and how
aggressive the virus is.

     Some viruses will mutate or change vital characteristics as they migrate to
a new host.  This mutation can make it difficult to create new, safe vaccines or
treatments that keep pace with the spread of the virus.

Vaccine:
- --------

     Vaccines contain antigenic components. These components (live or dead parts
of a virus) antagonize or stimulate the immune system to produce antibodies.  By
stimulating  an immune  response  (but not the  disease),  vaccination  leads to
immunity for a certain  micro-organism and protects against subsequent infection
by that organism.

     If a virus  mutates as discussed  earlier,  it is likely that a new vaccine
will have to be created to match the characteristics of that virus.

     There  are  two  types  of  vaccine,  activated  and  inactivated.  The key
difference is that inactivated  vaccines (such as those produced by Sinovac) use
inactive (dead) components of the actual virus. Inactive vaccines provide enough
genetic  material for the body to recognize and successfully  create  antibodies
but do not carry the obvious risk of using live or active components.

     A virus often needs  certain  basic  nutrients  and  conditions in order to
survive and  replicate.  The most basic of those is water,  which is why viruses
are most  commonly  transmitted  through  fluid,  be it a water supply or bodily
fluids.

     To give some idea of how fast and effectively a virus can spread, Hepatitis
A infects  between 1.5 and 10 Million  people every year and more than 2 Billion
people  have been  infected  by  Hepatitis  B which is one  hundred  times  more
infectious than AIDS.






                                       10




Human Suffering:
- ----------------

     The  toll  on  humans  is  physical,  emotional  and of  course  financial.
Influenza,  Hepatitis and, more recently, SARS have all had a significant impact
on human life.

     Hepatitis  B leads to liver  diseases  that kill more than  500,000  people
every year.  Adding to these historical  viruses are new types such as Avian Flu
and SARS that are increasing the stresses,  costs and losses across industry and
health care sectors.

Pervasive Pan-Viral Transmission Patterns:
- ------------------------------------------

     Because  viruses like  Influenza,  Hepatitis and SARS spread so rapidly and
effectively,  international  health authorities and over numerous countries have
recognized that prevention  through mass vaccination is more cost effective than
cure.

     With increasing  national and  international  travel combined with carriers
that never show  symptoms  as well as lengthy  incubation  periods  the need for
prevention  is  becoming   increasingly   clear.  World   governments,   medical
associations and international  health authorities are all pushing for increased
vaccination policies to prevent the problem before it occurs.

          Historic Recurring Viruses
          --------------------------

     Hepatitis A
     -----------

     Hepatitis A is endemic in developing  nations like China.  Hepatitis A is a
liver  disease  that  makes the liver  swell and  prevents  it from  functioning
properly.  It is caused by the  hepatitis A virus  (HAV).  Often,  a person with
hepatitis A shows no signs or  symptoms.  If  symptoms  are  present,  these may
include jaundice (yellowing of eye and skin) and fever. Hepatitis A will leave a
person  incapacitated  or weakened for a long time,  up to several  weeks,  even
months.

     The Hepatitis A virus is shed in the stool of an infected person during the
incubation  period of 15-45 days before symptoms occur and during the first week
of the  illness.  Blood  and other  bodily  secretions  may also be  infectious.
Hepatitis  A is  contagious  and can be spread by close  personal  contact  with
someone carrying the virus. Hepatitis A can also be contracted by consuming food
that has been prepared by someone with the disease or by drinking water that has
been  contaminated  by  Hepatitis A (in parts of the world with poor hygiene and
sanitary conditions).  The virus does not remain in the body after the infection
has  resolved,  and there is no carrier  state  (i.e.  a person who  spreads the
disease to others but does not become ill).

     Hepatitis  A can be  passed to  anyone  but  those  who are more  likely to
contract  the virus are  persons  who live with  someone  who has  Hepatitis  A,
children who attend  daycare,  daycare  personnel,  homosexual  men,  people who
travel to foreign  countries where  Hepatitis A is common and  intravenous  drug
users.

     Good personal hygiene and proper  sanitation,  such as washing hands before
eating,  can help  prevent  hepatitis A. The safest and most  effective  form of
protection is vaccination.







                                       11




     Hepatitis B
     -----------

     Hepatitis B is one of the major  diseases of mankind and  continues to be a
serious global public health issue.  It is  preventable  with safe and effective
vaccines that have been  available  since 1982, yet  information,  education and
cost have often  prevented the necessary  mass  vaccination  programs that would
help defeat the virus.

     Of the estimated 2 billion people who have been infected with the hepatitis
B virus (HBV), more than 350 million have chronic (lifelong)  infections.  These
chronically  infected  persons are at high risk of death from  cirrhosis  of the
liver and liver cancer, diseases that kill about one million people each year.

     Although the vaccine will not cure chronic  hepatitis,  it is 95% effective
in  preventing  chronic  infections  from  developing,  and is the first vaccine
against a major human cancer.

     Unfortunately, however, the children in the poorest countries, who need the
vaccine the most,  have not been receiving it because their  governments  cannot
afford it.  Fortunately,  a hepatitis B vaccine  will soon be available in these
countries  with  the  assistance  of  the  Global   Alliance  for  Vaccines  and
Immunization (GAVI) and the Global Fund for Children's Vaccines.

     Sinovac's  safe and effective  Bilive product can be priced to support such
international programs and still provide significant net profit.

     Influenza
     ---------

     Influenza  (commonly called "the flu") is a contagious  respiratory illness
caused by influenza  viruses.  Infection  with  influenza  viruses can result in
illness ranging from mild to severe and life-threatening complications.

     There are three types of the virus:

  - Influenza A viruses that infect mammals (humans, pigs,  ferrets, horses) and
    birds
  - Influenza B viruses that infect only humans
  - Influenza C viruses that infect only humans

     All type A influenza viruses, including those that regularly cause seasonal
epidemics  of influenza in humans,  are  genetically  labile and well adapted to
elude host defenses.  Influenza  viruses lack mechanisms for the  "proofreading"
and  repair  of  errors  that  occur  during  replication.  As a result of these
uncorrected  errors,  the genetic  composition  of the  viruses  changes as they
replicate in humans and animals,  and the existing strain is replaced with a new
antigenic  variant.  These constant,  permanent and usually small changes in the
antigenic composition of influenza A viruses are known as antigenic "drift".

     The  tendency  of  influenza  viruses to  undergo  frequent  and  permanent
antigenic  changes  necessitates  constant  monitoring  of the global  influenza
situation and annual adjustments in the composition of influenza vaccines.








                                       12




     Influenza  viruses  have a second  characteristic  of great  public  health
concern - influenza A viruses,  including subtypes from different  species,  can
swap or "re-assort"  genetic  materials and merge. This  re-assortment  process,
known as  antigenic  "shift",  results in a novel  subtype  different  from both
parent viruses. As populations will have no immunity to the new subtype,  and as
no existing  vaccines can confer  protection,  antigenic shift has  historically
resulted in highly lethal pandemics. For this to happen, the novel subtype needs
to have genes from human  influenza  viruses that make it readily  transmissible
from person to person for a sustainable period.

     Research  has  shown  that  antiviral  drugs  are  effective  for  both the
prevention  (chemoprophylaxis) and early treatment of influenza, if administered
within  48  hours  following  the  onset  of  illness.  During  normal  seasonal
epidemics,  antivirals are  considered an important  adjunct to vaccination as a
strategy for reducing the medical and economic  burden of  influenza.  Their use
can  reduce  the  duration  of  uncomplicated  disease  and  the  likelihood  of
complications requiring anti-microbial treatment and possibly hospitalization.

     Sinovac  intends  to launch  its Split Flu  Influenza  vaccine by the first
quarter of the 2005 calendar year.

          New Viruses
          -----------

     SARS
     ----

     The SARS  epidemic,  which claimed 774 lives  worldwide  earlier this year,
further  fuelled  individual  interest  for various  vaccine  shots.  Demand for
different vaccine shots in Beijing, for instance,  went up by 10 times since the
outbreak of SARS, government statistics indicate.

     The continuing  appearance of new infectious diseases,  especially the SARS
outbreak in 2002, has resulted in a heightened worldwide demand for vaccines.

     At a convention of leading SARS  researchers  from 15 nations in late 2003,
the  greatest  concern  was that no country is  adequately  prepared to face the
grave health threats posed to their urban  populations by such viruses.  Nor are
their  regional  and  national  economies  braced  for  the  seriously  negative
financial impact that SARS has already caused in many places.  For instance,  it
is estimated that SARS cost Southeast Asian nations approximately US $60 billion
in  economic  losses in 2003.  Scientists  at the  convention  concluded  that a
recurrence  of SARS (which  spread to over 35 countries in a matter of months in
2003) could develop into a full-blown global pandemic.

     Avian Flu
     ---------

     Avian  influenza  (also  known as the  "bird  flu") is a type of  influenza
virulent in birds.  It was first  identified  in Italy in the early 1900s and is
now known to exist worldwide.

     The  causative  agent is the avian  influenza  (AI)  virus.  AI viruses all
belong to the  influenza  virus A genus of the  Orthomyxoviridae  family and are







                                       13




negative-stranded, segmented RNA viruses. Avian influenza spreads in the air and
in  manure.  Wild fowl often act as  resistant  carriers,  spreading  it to more
susceptible  domestic stocks.  It can also be transmitted by contaminated  feed,
water, equipment and clothing;  however, there is no evidence that the virus can
survive in well cooked meat.

     The  incubation  period  is 3 to 5 days.  Symptoms  in  animals  vary,  but
virulent strains can cause death within several days.

     Avian Influenza in Humans
     -------------------------

     While avian  influenza  spreads  rapidly  among  birds,  it does not infect
humans   easily,   and  there  is  no  confirmed   evidence  of   human-to-human
transmission.  Of the 15 subtypes known, only subtypes H5 and H7 are known to be
capable of crossing the species barrier.

     Conditions  favorable for the  emergence of antigenic  shift have long been
thought to involve  humans  living in close  proximity  to domestic  poultry and
pigs.  Because pigs are  susceptible  to infection with both avian and mammalian
viruses,  including  human strains,  they can serve as a "mixing vessel" for the
scrambling of genetic  material from human and avian  viruses,  resulting in the
emergence of a novel subtype.  Recent events,  however, have identified a second
possible mechanism. Evidence is mounting that, for at least some of the 15 avian
influenza virus subtypes circulating in bird populations,  humans themselves can
serve as the "mixing vessel".

     The  symptoms  of  avian  influenza  in  humans  are akin to those of human
influenza,  ie. fever, sore throat,  cough and in severe cases pneumonia.  Human
deaths from avian  influenza  were unknown  until 1997,  when six people in Hong
Kong died from the particularly virulent H5N1 strain.

     In January  2004,  a major new  outbreak of H5N1 avian  influenza  surfaced
again in Vietnam and Thailand's poultry industry, and within weeks spread to ten
countries  and regions in Asia,  including  Indonesia,  South  Korea,  Japan and
China. Intensive efforts were undertaken to slaughter chickens, ducks and geese,
and the  outbreak  was  contained  by March,  but the total  human death toll in
Vietnam and Thailand was 23 people.

     It is feared that if the avian influenza  virus  undergoes  antigenic shift
with a human  influenza  virus,  the new  subtype  created  could be both highly
contagious and highly lethal in humans.  In February 2004, avian influenza virus
was  detected  in pigs in  Vietnam,  increasing  fears of the  emergence  of new
variant strains.

     In North America,  the presence of avian influenza was confirmed at several
poultry farms in British Columbia, Canada in February 2004.

     Avian influenza in humans can be detected reliably with standard  influenza
tests.  Antiviral drugs are clinically effective in both preventing and treating
the disease. Vaccines, however, take at least four months to produce and must be
prepared for each subtype.

Principal Products
- ------------------

     The Company has one licensed product, Healive(TM), selling in China and the
international  community.  The  Company  expects  the Chinese FDA to approve its
combined  Hepatitis A&B vaccine,  Bilive(TM) in the summer of 2004.  The Company
also expects the Chinese FDA to approve its influenza Split Flu Vaccine by 2005.

     In  addition  to these,  the  Company  is on the  leading  edge of  vaccine
research and development for SARS and Avian flu viruses.

     Healive(TM)
     -----------

     Healive(TM)  - is the  first  high-quality  Inactivated  Hepatitis  A (IHA)
vaccine in China with private corporation  intellectual property rights. Healive
provides   1.3   billion   Chinese   citizens,    with   a   safe,    efficient,
environment-friendly  vaccine.  The  number  of the  potential  customers  keeps
increasing  when 20 million  babies are born each year.  As an IHA vaccine  that
meets international regulatory standards,  Healive is an excellent match to meet
the Chinese government's goal of eradicating Hepatitis A throughout the country.

     Scientific  testing indicates that the safety and immunogenicity of Healive
is excellent for both adults and children.

     Healive is produced by the Company's 51% owned subsidiary,  Sinovac Biotech
Co., Ltd., a company organized under the laws of the People's Republic of China.

     Bilive(TM)
     ----------

     Bilive(TM)  -  Hepatitis  B virus  (HBV)  infects  about  50-70% of China's
1.3-billion  citizens at some point in their lives. To address this problem, the
Company is planning a near-term  launch of its combined  Hepatitis  A&B vaccine,
Bilive, for the domestic market and later for the international marketplace.

     Bilive(TM)  is  a  combined  vaccine  formulated  by  purified  inactivated
Hepatitis A virus antigen and  recombinant  (yeast)  Hepatitis B surface antigen
(HBsAg),  adsorbed onto  aluminium  hydroxide.  This vaccine  induces the body's
immune system to generate antibodies as a reaction against Hepatitis A virus and
Hepatitis B viruses.  As such it can be used for prevention of infection  caused
by Hepatitis A virus and Hepatitis B virus. The vaccine comes in two forms based
on the age of the patient.

     Bilive(TM) junior is suitable for use in non-immune  infants,  children and
adolescents  from one year up to and  including 15 years who are at risk of both
Hepatitis A and Hepatitis B infection.

     Bilive(TM)  adult is suitable for use in non-immune  adults and adolescents
16 years of age and above who are at risk of both  Hepatitis  A and  Hepatitis B
infection.

     Bilive(TM) can be recommended for persons who remain in the vicinity of HAV
and/or HBV, users of illicit intravenous drugs, homo and bisexuals, hemophiliacs
who receive  therapeutic  blood products,  persons with  nephropathy who receive
dialysis treatment, and those who receive long term blood dialysis.







                                       15




     The standard  primary course of  vaccination  with  Bilive(TM)  consists of
three doses.  The first  administered at the selected date, the second one-month
later and the third six months after the first dose. Once initiated, the primary
course  of  vaccination  should  be  completed  with the same  vaccine.  Booster
vaccination with the combined vaccine can be recommended 5years after initiation
of the primary course.

     Bilive  side  effects  are  rare  and of low  intensity.  The  most  common
reactions were those at the site of injection,  which included  transient  pain,
redness  and  swelling.  Systemic  adverse  events  seen were  fever,  headache,
fatigue, nausea and vomiting. These events were transient,  only rarely reported
and were considered by the subjects as mild.

     Split Flu Influenza Vaccine
     ---------------------------

     Split Flu  Influenza  Vaccine - The  influenza  vaccines  used in the world
include whole-particle,  split and subunit vaccines. For children under 12 years
whole-particle  vaccine is prohibited  since its has severe  adverse  reactions.
Split  vaccine is the one that will be used most widely all over the world.  The
Company began the development of influenza  split vaccine 2 years ago.  Clinical
trials for this product have  recently been  completed  and are currently  being
evaluated. 500,000 doses of split flu vaccine are expected to be produced in its
first year after finishing the construction of the manufacturing  facility,  and
then 2 millions doses per year thereafter.

     SARS
     ----

     SARS - In May of  2003,  the  "Programs  of  Key  Technology  and  Products
Research and Development for SARS Prevention and Control" included  "Inactivated
SARS vaccine Research and Development"  into the important "863 Plan" of China's
"Tenth Five-Year Plan". One year later, on May 23, 2004 - the Company  announced
that it had commenced  Phase I human  clinical  trials of its SARS vaccine.  The
first  subjects  were  injected  with the vaccine on the 22nd of May 2004 at the
China-Japan Friendship Hospital in Beijing, China.

     If Phase I testing is successful, then the second phase of clinical testing
will have more  participants  from a wider  demographic  range and will  include
double blind trials  involving  control  groups to determine the efficacy of the
trial drug in multiple trial centers.  Phase III of clinical  trials is expected
to be much the same as Phase II but will be conducted on a much larger scale (if
a major outbreak of SARS presents the opportunity for these pivotal trials). The
successful  completion  of  such an  initiative  could  conceivably  lead to the
commercialization  of a SARS  vaccine  within 18  months - one that  also  meets
Western standards of safety and efficacy.  Notably,  a pharmaceutical  product's
approval  timeline in the United  States may sometimes be expedited to as little
as six months if it is designed to treat or prevent a  life-threatening  illness
for which there are few or no alternative therapies.

     Avian Flu
     ---------

     Avian Flu - The Chinese  government  assigned  the task of Avian Flu R&D to
the  Company  and the  Center  for  Disease  Control  of China on the latest Key
Science-Technology  Project of the  National  'Tenth  Five-Year-Plan'  of China,
called "Research and Development of a New Human Influenza Vaccine".  The Company







                                       16




finished  the  research  protocol  early in 2004 and started  working  towards a
vaccine.  The leading  world health  authority  influenza  network  provided the
prototype bird flu virus to vaccine makers around the world.

Research and Development
- ------------------------

     Disease  prevention  is a long march.  The Company will strive to integrate
our research & development,  and marketing strategies,  so as to supply more and
more new products to eliminate human diseases.

     The  Company,  through  the  co-operation  with  local and  internationally
well-known  universities,  colleges and institutes,  and in consideration of the
need of disease control in China, researches on and develops new vaccines, takes
benefits  from the mature  technology  in the world,  reconstructs  the existing
vaccine products, participates in world-wide competition in vaccine markets, and
makes effort to achieve more abundant and perfect products.

     In this  regard,  a  number  of  leading  Chinese  scientific  and  medical
institutions,  such as Beijing  University  and the  Chinese  Academy of Medical
Sciences,  are collaborating with the Company in the research and development of
new and improved vaccine biotechnologies.  In particular, the Chinese government
is  marshalling  all of its  scientific  resources  to  the  Company's  aid in a
collaborative  effort to  develop  on an  expedited  basis a safe and  effective
vaccine for SARS.

Safety and Quality Assurance
- ----------------------------

     In accordance with FDA Good  Manufacturing  Practice ("GMP")  requirements,
the Company has written and  implemented a quality  assurance  validation  plan,
procedures,  and a complete  documentation  system. The Company's  manufacturing
facilities for Hepatitis  vaccines,  HealiveTM and BiliveTM,  have both received
the Certificate of Good Manufacturing  Practices for Pharmaceutical Products (n.
2515 and 2514) issued by Chinese  State Food and Drug  Administration  ("SFDA").
Sinovac's  facilities  also  meet the GMP  requirements  of the US Food and Drug
Administration.  The Company has strict control  management of its staff,  plant
environment,   support   facilities,   raw   materials,   hygiene,   validation,
documentation,  manufacturing  process,  quality control,  product selling, post
selling,  and  pharma-covigilance.  The Company's personnel are trained on these
procedures and documentations routinely to ensure a finely running comprehensive
quality assurance system and the quality of the finished products.

     The Company bases all its operations on its excellence in service  concept.
To meet  the  Company's  high  goals,  the  Company  has  established  a team of
nationwide  well-known  experts,  professors  and  doctors  to  provide  vaccine
customers with support.  This team of experts provides the core of the Company's
emergency  advisory  response  center,  which  promises to take action within 24
hours in case of emergency, 365-days a year.

     The  Company's  facilities  are fully  compliant  with world  advanced  GMP
Quality Assurance System (QAS),  international  standards on  bio-pharmaceutical
manufacturing. The design of the plant for the production of the Healive vaccine
was done by a well-known European company in accordance with the U.S. FDA and EU
GMP requirements,  with major equipment and facilities imported from Europe, and







                                       17




the installation and debugging processes completed in a key-handing-over  way by
an European  pharmaceutical  engineering company. The Company's plant has passed
the validation done by SVS - a FDA designated GMP validation consulting company.

Market Prospects
- ----------------

     The global  statistics speak for themselves,  billions  infected,  millions
more every year and a continually  growing  population  providing new vulnerable
hosts.

     The massive increase in international travel through airports over the past
forty years and a minimum  incubation for any of the major viruses of three days
means that an  infected  individual  can pass a virus onto  multiple  continents
before he  realizes  he is ill.  If he only passes on the virus to one person in
each continent, it's enough to start a global epidemic.

     This is why the leading  international  health  authorities and governments
around the world have stated that  vaccination is the most cost effective way to
deal with viral threat.

     116 countries have now initiated  childhood  vaccination  programs and more
are  following.  The only  barriers  that stand in the way of success  for these
initiatives are cost and quality. There are few of the `inactive' safer vaccines
available and they are costly despite  significant  price drops over the last 15
years.

     The existing  vaccine  suppliers  use the lack of  competition  to keep the
price high. Research and development for existing products took place many years
ago with less  advanced  technology  and as a result  there  are still  costs to
recover.  Subsequently,  many western  pharmaceutical  companies  will not enter
poorer countries,  as their pricing  structures do not give them the flexibility
to  make  an  effective  bid.  This  means  that  despite   global   vaccination
initiatives,  only the more  financially  able countries can implement  programs
using western vaccine suppliers.

     According to the U.S. investment dealer,  Merrill Lynch, the global vaccine
market was worth about US $5.4 billion in 2001.  Merrill  Lynch  forecasts  that
this  figure  will  reach US $10  billion  within 5 years.  This  represents  an
increase  of  almost  100% -- a figure  that  eclipses  forecasts  for any other
pharmaceutical sector,  including the prescription drug market. A key driver for
the  growth in vaccine  sales is the fear of the  emergence  or new  potentially
lethal "super viruses" such as SARS and avian influenza.

     Many biotechnology and pharmaceutical  companies are vying to capitalize on
this booming market. Accordingly, the Company is in an enviable position in that
the company is ideally  positioned  to be a market leader in China and elsewhere
in Southeast Asia -- collectively  the fastest growing and most prolific vaccine
marketplaces in the world.






                                       18




The Company's Market
- --------------------

     The Company has three markets,  each with three  subsections.  The first of
these, as with most companies is the local domestic market - that being China.

     China has a population  of  approximately  1.3 billion,  with 15-20 million
babies  born  each  year  and  an  increasing  elderly  population.   These  two
demographic  groups are the largest  vaccine  consumers.  According  to official
data,  the  population  aged 60 and over has reached 134 million  with an annual
rate of increase of about 3.2 %. Hence, the need to address  healthcare costs to
an aging population is a pressing concern of China's federal government.  One of
the most effective ways of containing such costs is through government-supported
vaccine   inoculations   against  such  infectious  diseases  as  hepatitis  and
influenza.

     The Chinese  government has targeted disease  prevention as a key sector of
the country's  pharmaceutical  industry  development  plans and the reforms will
further accelerate demand growth.  According to Wang Hexiang, former minister of
public health for China's federal government, the federal government is infusing
1.2  billion  yuan  (US$145  million)  in  2004 to set up a  nationwide  disease
prevention  system.  In 2002,  government  funding  was only  800  million  yuan
(US$96.4 million.).

     According to studies  conducted  by the  pharmaceutical  giant,  SmithKline
Beecham, China's  biopharmaceutical market is predicted to be the largest in the
world by 2010. Moreover, the most vibrant sector in this industry is expected to
be the market for immunology biotechnology.

     The vaccine  marketplace  in China can be sub divided into three  different
marketing channels as described below:

     Public market:           central or local  government  funding for vaccines
     --------------           to combat common virile diseases such as Hepatitis
                              B (for infants and school children).

     Private market:          "Out-of-pockets"  cash market for  individuals who
     ---------------          can  personally  afford  vaccines for Hepatitis A,
                              rabies,    influenza,    pneumonia    and    other
                              opportunistic illnesses.

     Third party market:      This would involve payment of inoculations for all
     -------------------      types  of  common  viral  illnesses  by  privately
                              funded or  government-assisted  medical  insurance
                              programs.

     Local Influenza Market
     ----------------------

     In China,  the  demand for  influenza  vaccines  is growing  exponentially.
During the 2002/03  influenza  season,  a total of 6.7 million  doses were sold.
Last  year,  that  figure is  estimated  to have more than  doubled  to about 15
million  doses. A continued  surge in demand is anticipated  during the next few
years as a result of a number of factors,  which include new  initiatives on the
part of the federal  government to encourage  citizens to reinforce their immune
systems  against  influenza,  as well  as a  possible  resurgence  in  SARS.  In







                                       19




addition,  the advent of Chinese  citizens  having  greater access to disposable
income means that tens of millions of Chinese can now afford influenza shots.

     The Company estimates that demand could reach 20 to 30 million doses within
a couple of years. A current  shortage in the supply of influenza shots in China
is an  imperative  that the Company  intends to address once approval is granted
for the launch of its proprietary  influenza vaccine. The current Chinese supply
of influenza  vaccines,  at approximately six million doses annually,  falls far
short of  meeting  China's  demand  for at least 15  million  doses by 2005.  At
present there are several domestic suppliers and three foreign suppliers with no
market leader.

     Southeast Asian Region and Developing Countries
     -----------------------------------------------

     The  Company's  second  market  sector is still close to home,  where there
exists one of the most epidemic areas of the Hepatitis A virus,  and in at least
one  regard,  cost is equally as  important  as safety.  Many low income or poor
health infrastructure countries all require safe, efficient vaccines. Currently,
the  Company  is  preparing  the  registration   information  for  each  country
co-ordinated  with their  international  market developing arms. The first eight
countries for which we intend to submit  registration  information are Thailand,
Vietnam, Malaysia, Philippines, Mexico, Brazil, Indonesia and Sri Lanka.

     The Southeast Asian region and other developing  countries  together are at
least equal to the local Chinese  market and have similar  statistics  for birth
rates and those above 60 years of age.

     Global Consumers
     ----------------

     For many years now, health  authorities,  practitioners  and governments in
western  countries  have been under  pressure to improve  medical  care and keep
costs down if not reduce them. News stories in most countries complain about the
ever-increasing costs, longer waiting lines and reduced quality of service. As a
result,  the purchasing power within these  institutions is being exercised more
by accountants and contract negotiators as they search for savings. This creates
a growing  demand for cost effective  drugs and treatments  that are not locally
sourced.  Provided  the  quality is seen as  equivalent,  more and more  western
medical  service  providers will look to source their  provisions  from the most
cost effective source.

Customer Types
- --------------

     Government
     ----------

     Governments  across the globe are pledging their support,  financially  and
organizationally  to vaccine  initiatives.  Where Rubella (measles) and Smallpox
were the traditional child  vaccinations,  Hepatitis and Influenza are now being
added to  increase  the scope of  preventative  medicine.  Government  sponsored
programs  tend to be aimed at `most at risk'  groups and are often  directed  at
children more than the elderly.








                                       20




     International Nongovernmental Organizations
     -------------------------------------------

     Since 1991,  international  health  authorities have urged all countries to
add Hepatitis B vaccines into their national immunization  programs. As of March
2000, 116 countries had included  Hepatitis B vaccine in their national programs
including most  countries in Eastern and South- East Asia, the Pacific  Islands,
Australia, North and South America, Western Europe and the Middle East. However,
many low income countries in sub-Saharan  Africa, the Indian subcontinent and in
the Newly Independent States do not use the vaccine.  The price of the Hepatitis
B vaccine  has been one of the main  obstacles  to its  introduction  in many of
these countries.

     An organization  committed to the vaccination of children  against diseases
is The Global Alliance for Vaccines and Immunization (GAVI) which was created in
1999. GAVI has introduced a new approach to  international  health funding - the
Global Fund for Children's  vaccines  (GFCV).  This fund will help 74 low-income
countries to reinforce their national vaccine  programs and introduce  Hepatitis
B,  yellow  fever and  hemophilia  influenza  type B (HIB)  vaccines  into their
national immunization programs.

     The Company is planning to develop the vaccines which are on the order list
of those nongovernmental organizations and EPI in order to capture the market of
low-price, but big-demand vaccine.

     Private Citizens
     ----------------

     Rising  incomes have  contributed  to the increased  demand for  commercial
vaccines.  Many  of  those  in  the  higher  wage  bracket  choose  to  pay  for
vaccinations.  This growing  market is supplied by  increasingly  cost conscious
physicians in private health centers.

Marketing Strategy
- ------------------

     First the Company intends to target progressive  geographic  expansion with
its family of vaccines that target historically devastating viruses. The Company
is building a sales  organization in the Chinese domestic  market.  Concurrently
with its domestic  marketing  plan, the Company is  establishing a marketing and
sales presence in South East Asia and other developing  countries  through local
distributors,  who  have  over 10  years  experience  of  commercialization  and
registration  for  vaccines  and  other   pharmaceuticals   through  their  well
established governmental relationship and local selling channels.

     The second  prong of the  Company's  marketing  strategy is  contingent  on
creating a blockbuster  vaccine for defeating  emerging  viruses such as SARS or
the Avian Flu. In such case,  the first to market  advantage  opens the door for
sales to the international  market.  In such a scenario,  the Company intends to
enter the international  market,  with a worldwide sales network of professional
sales teams, well-organized selling channels, a sound customer-credit management
scheme, and an efficient logistics system.






                                       21




     Domestic Market Strategy
     ------------------------

     The Company's  domestic marketing is greatly enhanced by Chinese government
programs for inactivated  Hepatitis A Vaccine,  inactivated SARS vaccine and new
Human Influenza vaccine.

     As part of the Company's private marketing strategy, it intends to continue
to pursue a strategy of first launching its vaccine  products in market segments
in China that present the highest  concentrations of people with higher earnings
bases.  Subsequent to this  initiative,  the Company  intends to  systematically
expand its sales reach into less affluent urban areas and less  populated  rural
provinces.  Accordingly,  the Company intends to penetrate these various markets
in descending order with Segment A representing the most affluent,  high density
areas and  Segment D  representing  lesser  populated  areas with the lowest per
capita average incomes.

     These market demographics are outlined below:

     Segment A:  Beijing / Guangdong / Jiangsu / ZhejiangTianjin
     Segment B:  Liaoning  / Hebei /  Shandong  / Fujian /  Shanghai  / Hainan /
                 Shaanxi /  Chongqing  / Guangxi
     Segment C:  Helongliang / Jilin/Shanxi / Sichuan / Yunnan / Anhui
     Segment D:  Henan / Hunan / Jiangxi / Guizhou/

     Southeast Asia Regional Market Strategy
     ---------------------------------------

     The  Company  intends to  develop  an  overseas  sales  strategy  initially
targeting Southeast Asian nations by way of a joint venture  licensing/marketing
agreement with a successful South Korean pharmaceutical  company called Innopath
International  ("Innopath").  Many management personnel in Innopath have over 20
years experience in international  vaccine marketing and they have over 10 years
working experience with distributors with many South Asian countries.

     International Market Strategy
     -----------------------------

     The Company  intends to register with the European  Union (EU) and the U.S.
Food and Drug Administration (FDA) with the goal of meeting FDA and EU approvals
for one or more of its in-development vaccine biotechnologies.  The most obvious
candidates  at this  time  are the  Company's  experimental  avian  flu and SARS
vaccines  as there are  presently  no viable  immunology  treatments  to protect
against SARS and avian flu in the United States or anywhere  else.  The prospect
of  being   "first  to  market"   with   potentially   life  saving   immunology
biotechnologies  offers the Company a clear  competitive  advantage  in terms of
gaining significant market share.

     The Company expects to primarily  target  developing  nations where Western
manufactured  hepatitis  vaccines are  typically  prohibitively  expensive.  The
Company  expects to be  registered  for the sale of its Hepatitis A and Combined
Hepatitis A&B  immunology  biotechnologies  in at least 34 countries by the year
2009.






                                       22




     Similarly,  the Company  expects to  commercialize  its  proprietary  human
influenza  vaccine by the first quarter of 2005 with the goal of also  targeting
the majority of other  developing  Southeast  Asian markets within the next five
years.

     The  Company  has also signed a  marketing  agreement  with China  National
Medicine & Health Products  Import/Export  Corporation (MEHECO) to represent its
products in Brazil. MEHECO is one of the largest medical import/export companies
in China,  specializing in pharmaceuticals,  health products,  hospital supplies
and  chemicals.  It has  achieved  more than  US$6.3  billion in sales since its
inception 18 years ago.  MEHECO is a global leader in vaccine sales in more than
one hundred countries.

     The  Company  intends to  accelerate  its  international  market  growth by
placing a priority on sales agreements with companies that can take advantage of
the Company's R&D capabilities.

Competition
- -----------

     Domestic Chinese Competition
     ----------------------------

     The  existing  domestic  vaccine  industry  in China only caters to a small
fraction  of  the  Chinese   population  at  this  time.  Most  Chinese  vaccine
manufacturers are very small-scale operations that use dated biotechnologies and
experience  high  operating  costs.   Furthermore,   due  to  the  technological
limitations  of these  companies,  most of their  vaccines have a relatively low
efficacy  rate  (compared  to Western  counterparts),  as well as a  significant
incidence of potent side effects. For instance,  cheap live attenuated Hepatitis
A vaccine  has poor  stability  profile.  It  requires  strict  conditions  when
delivering.  When the surrounding  temperature is above 8 degrees Celsius, it is
very  possible  for the  Hepatitis A vaccine to lose its  efficacy.  And in many
undeveloped areas in China, it is unlikely to guarantee the delivery  conditions
for live  attenuated  vaccine.  Therefore,  when the vaccine is delivered to the
destination,  it has been ineffective.  It is very important to notice that none
of the  countries  in the world,  except  China have  approved  live  attenuated
vaccine to be used.

     Despite low price  points for their  immunology  biotechnologies,  combined
sales for all of these  manufacturers  only amount to about  US$60-73  million a
year,  as compared to the equally  small  US$24.2  million  generated by Western
vaccine  manufacturers  (whose  products are  prohibitively  expensive  for most
Chinese citizens).  Furthermore,  most Chinese vaccine manufacturers are legally
required to allocate up to 70% of production  capacity to the  manufacturing  of
vaccines for federal government immunology programs. The profit margins for such
initiatives tend to be slender.

     Ultimately,  the greatest limitation faced by Chinese vaccine manufacturers
concerns an inability to access major  financing  for  expansion  purposes.  The
venture  capital market is still in its infancy in China and accessing  funds is
problematic,   particularly   when  these   companies  are  marketing   inferior
biotechnologies. Accordingly, China suffers from a major shortfall in the supply
of safe and efficacious vaccine biotechnologies. For instance, only about 1.5% -
2.5%  of  the  Chinese  population  are  consumers  of  influenza  vaccines.  By
comparison,  this figure is as high as 26% in the United States and up to 20% in






                                       23




neighbouring  South  Korea.  Such  statistics  attend  to the  largely  untapped
marketplace for the Company's anticipated soon-to-be-launched influenza vaccine.

     Whereas this marketing  opportunity also extends to Western  pharmaceutical
companies with influenza  vaccines that are comparable in safety and efficacy to
the Company's influenza vaccine, however, the Company's lower price point offers
a clear competitive advantage. Influenza vaccines may be sponsored or subsidized
by many Western governments or by private medical insurance  programs.  However,
most Chinese  citizens have to pay for these  vaccines out of their own pockets.
Therefore,  the Company believes that this price-sensitive  consumer market will
favour the company's influenza vaccine over more expensive Western  competitors.
The same rationale likely applies to the Chinese municipal  governments that are
beginning to allocate funds to provide  influenza shots to low income  municipal
dwellers. Furthermore, the advent of private medical insurance programs in China
also promises to benefit the Company for similar cost-related reasons.

     International Competition
     -------------------------

     Competition  from  other   biomedical   companies  in  the  global  vaccine
marketplace is a risk factor.  In a rapidly changing field,  this competition is
most likely to come from well-established  biopharmaceuticals  with deep pockets
and  a  proven   track   record   for   successful   product   development   and
commercialization.  Therefore,  there can be no  assurance  that such  potential
rivals will not develop more  proficient and more affordable  vaccine  products.
Also, the prospect of another  immunology  company in North America or elsewhere
commercializing the world's first SARS or avian influenza vaccines is a distinct
possibility.

Administration
- --------------

     During  the  period  commencing  January to  December  of 2003 the  average

                                       25




Plants
- ------

     The design of the  Sinovac  Biotech  Co.,  Ltd.  plant in  Beijing  for the
production of the Healive vaccine was done by a well-known  European  company in
accordance  with the US FDA and EU GMP  requirements.  The major  equipment  and
facilities  were  imported  from  Europe,  and the  installation  and  debugging
processes were completed in a key-handing-over way by a European  pharmaceutical
engineering company. The plant has the validation done by SVS - a FDA designated
GMP validation consulting company.

     The Sinovac  manufacturing  plant for  Inactivated  Hepatitis A vaccine has
obtained  the  GMP  certificate   issued  by  the  China  State  Food  and  Drug
Administration (SFDA) in March 2002.

     Tangshan  Yian  Biological  Engineering  Co.,  Ltd.  ("Tangshan  Yian") was
founded in 1993. Its facility is located in the New Hi-tech  Development Zone of
Tangshan  City,  connected by  superhighways  to Beijing,  150 kilometers to the
east.  Tangshan  Yian's plant was built in  accordance  with the  Pharmaceutical
Industrial  Standards and Regulations of China, which are based on international
standards.  The plant itself is 4300 square  meters,  which includes a level III
Biological Safety Laboratory,  Cell Culturing  Workshop,  Pilot Trial Production
Workshop,  Reagents Manufacture Workshop,  and Research Lab for R&D of the Split
Flu  Vaccine.  The plant is situated on 20,000  square  meters of land,  and has
reserved an additional 10,000 square meters in anticipation of future expansion.

     Tangshan  Yian  provides the Company with a low-cost R&D and  manufacturing
base. The advantages of Tangshan  Yian's  state-of-the-art  facilities  expanded
manufacturing  capabilities and its talents will enhance the competitive ability
of the Company on research and production.

     The clinical  trials on split flu vaccine have been finished.  A production
line with GMP standards is being built at the Tangshan Yian plant.

     Chinese State Food and Drug Administration approved the Company to commence
the clinical research on its Inactivated SARS vaccine. The Company's subsidiary,
Tangshan  Yian,  will produce the first 20,000 doses at its  world-class  P3 Lab
(BL3). Currently, there are only a few of such laboratories in the world.

     The Company will work on New Human Influenza  Vaccine (Human Used Avian Flu
Vaccine)  Development  Project with the Chinese  Center for Disease  Control and
Prevention at its Tangshan Yian facility.  The Company has already  finished the
research protocol and has started working towards a vaccine.

Equipment

centralized. It also includes the necessary establishment, such as dressing room
and air brake. The design,  preparation,  fire control,  environment protection,
labor  protection,   and  energy  saving  of  heating,   ventilation,   and  air
conditioning are based on GMP standards and relative domestic requirements.


ITEM 5 - OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A.   The Company
     -----------

     Year ended December 31, 2003 compared with the year ended December 31, 2002
     ---------------------------------------------------------------------------

Liquidity and Capital Resources
- -------------------------------

     Our  primary  liquidity  requirements  are  for  working  capital,  capital
expenditures,  research and  development.  Our primary sources of liquidity have
been cash provided by operations,  borrowings  and stock plan. The  availability
and attractiveness of any outside source of financing will depend on a number of
factors,  some of which relate to our financial  condition and performance,  and
some of which are beyond our  control,  such as  prevailing  interest  rates and
general economic conditions. There can be no assurance that additional financing
will be available, of if available, that it will be on terms we find acceptable.

     Cash and cash  equivalents  increased by  $1,107,453 to $1,420,047 in 2003,
from $312,594 in 2002.

     Net cash  provided by  financing  activities  increased  by  $1,443,134  to
$2,895,793 in 2003, from $1,452,659 in 2002. This increase is primarily  related
to the subscription received of $1,031,959.

     In 2003,  cash used by  investing  activities  decreased by  $1,318,392  to
$758,959.  This cash was used to purchase plant equipment,  totalling  $348,190,
and payment for Licenses and permits, $410,769.

         Cash used in operating activities decreased by $23,798 to $1,029,143 in
2003, from $1,052,941 in 2002. The decrease is primarily related to the increase
of sales.

Results of Operation
- --------------------

     Vaccine  manufacturing is a special industry,  which requires high open-end
investment  in  order to  establish  the  proper  production  line to meet  high
requirements.  From building the  manufacturing  workshop to selling the product
into the market, Good Manufacturing  Practice certification is required, as well
as application  for New Drug Approval for  commercialization.  Therefore,  it is
expected that there will be a  significant  period of time from the beginning of
investment  until we  realize  return.  For  Sinovac,  the  construction  of the
manufacturing  workshop  was  completed  in 2002.  The  Hepatitis  A vaccine was
initially  launched into the market in Q4 of 2002. Profits for the sales of this






                                       27




vaccine were not realized by the end of 2003.  However, we expect to gain profit
by the end of 2004, since market share and sales numbers for HealiveTM  continue
to increase.  Concurrently,  we are going to launch the combined  Hepatitis  A&B
vaccine in the market. Part of the production of combined vaccine is going to be
completed in our manufacturing  workshop for Hepatitis A vaccine, which helps to
lower production costs.

     In 2003, total sales were  $2,838,933,  fourfold from $649,319 in 2002, and
net cash inflow in 2003 was $1,107,453.

     Cost of sales was $1,085,881 in 2003, and gross margin was 61.75%, compared
to the $251,711, 61.23% in 2002 respectively.

     Expenditures on sales and general administration was $1,629,118 compared to
$792,078 in 2002.  Expenditures were $354,173 for salaries and benefits compared
to  $218,613  in 2002,  $357,503  on  marketing  compared  to $181,935 in 2002.,
$399,317 on office  expenses  compared  to $226,961 in 2002,  $211,819 on travel
compared to $138,147 in 2002, $40,765 on rentals compared to $24,005 in 2002 and
$265,538 on professional and consulting fees compared to nil in 2002.

Research and Development, Patents and Licenses, etc.
- ----------------------------------------------------

     Research and Development expenditures totaled $232,785 in 2003, compared to
$24,535 in 2002.  The  increase in spending  from last year  primarily  reflects
ended Split Flu clinical  development  activity and  Hepatitis  A&B obtained new
drug license.

     The Company's most important  Research and  Development  achievement is the
inactivate  SARS vaccine.  The SARS Research and  Development  expenditures  was
granted by China government for $664,251 (RMB 5,500,000) which was deducted from
the total in Research and Development expenditures.

Trend Information
- -----------------

     The  Company's   corporate   strategy  is  aggressively   directed  towards
increasing sales during 2004. There are, however, some external factors that can
materially  affect the final sales  figures  for 2004.  These  external  factors
include the government approval process,  possible reoccurrence of diseases such
as SARS and new competition.

     Understandably,  government  delays in the sales approval for the Company's
combined Hepatitis A&B vaccine will correspondingly reduce sales figures for the
2004 period. In addition,  the reoccurrence of SARS or similar viruses cannot be
guaranteed and as such neither can sales of any respondent vaccine. Finally, the
market  sector  available  to the  Company  may be reduced  if a new  competitor
obtains approval to sell an equivalent product into the Company's market and the
Company does not increase promotional investment to compensate.

     The company  received its trading  symbol (NTFSF) from the NASD on February
21st,  2003.  The Company  now has a ready  market for its issued  shares  which
greatly enhance  opportunities  for additional equity financing in fiscal period
2004.

Material Commitments for Capital Expenditures
- ---------------------------------------------

     There were no material  commitments for capital  expenditures as of the end
of the latest  fiscal period ended April 30, 2003.  The existing  administrative
office  and  computer  hardware  includes  personal  computers,   printers,  fax
machines,  and backup  power  supply  units,  which  maintain  operation  of the
electronic office equipment during short power outages. This office equipment is
adequate to conduct current business operations.

     From this office, the Company conducts web-site design, marketing, customer
service support  services for the company's  websites.  The Company also manages
corporate  communications  and investor  relations from this office. The Company
maintains   access  to  the  Internet,   which  requires   personal   computers,
communications  hardware and software, and backup power supply units. All of the
above  commitments  were  settled in full  payment in cash from the  proceeds of
initial share  issuances and from the proceeds from the initial  promissory note
issued on July 15, 1999.

     During the fiscal  period ended April 30, 2003,  no further  payments  were
made to World  Gaming  under the  software  license  agreement  for the  initial
software setup and configuration.  As stated, the major capital  expenditure for
software was a one-time  setup and  configuration  fee of US$100,000  payable to
Starnet Systems  International  (formerly Softec Systems). An initial payment of
US$10,000.00 was paid upon execution of the agreement on July 15, 1999 leaving a
balance of US$90,000.00 payable upon completion of the  configuration/design  of
the software and  commencement  of live  operations.  In September of 2000,  the
balance of this one-time initial setup fee was  subsequently  negotiated to zero
as a result of a  compensation  agreement  with Starnet  Systems  International.
During the fiscal  period 2003,  only monthly  royalty fees (as a percentage  of
monthly total revenues), were paid to World Gaming.









                                       29




Material Commitments for Resources
- ----------------------------------

     No material  commitments  of resources  were made during the fiscal  period
ended April 30, 2003.

     Any material  commitments  of  resources  over the next year will be funded
from an  additional  financing  which may  consist  of a  combination  of equity
financing  and  issuing a  promissory  note with a possible  convertible  equity
component attached.

Impact of Inflation

     The  Company  believes  that  inflation  will  not  materially  affect  its
business.

ITEM 11 - QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     The  Company  is  operating  in China,  which may give rise to  significant
foreign currency risks from fluctuations and the degree of volatility of foreign
exchange  rates  between US dollars  and the  Chinese  currency  RMB.  Financial
instruments  that  potentially  subject the Company to  concentration  of credit
risks consist  principally of cash and trade receivables,  the balances of which
are stated on the  consolidated  balance sheets.  The Company places its cash in
high  credit  quality  financial  institutions.   The  Company's  customers  are
primarily pharmaceutical and biotechnology companies. One customer accounted for
15.83% of total sales for the year ended  December  31,  2003 and two  customers
accounted  for  41.42% of total  sales for the year  ended  December  31,  2002.
Concentration of credit risks with respect to trade receivables are limited to a
degree due to the  Company's  large  number of diverse  customers  in  different
locations in China. Ongoing credit evaluations of customers' financial condition
are performed and the Company  maintains  provisions for potential credit losses






                                       52




if  necessary.  The Company  does not require  collateral  or other  security to

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- -------------------------------------------------------



To the Board of Directors and Stockholders of
- ---------------------------------------------

SINOVAC BIOTECH LTD.
- --------------------
(formerly Net-Force Systems Inc.)

We have  audited  the  consolidated  balance  sheets  of  Sinovac  Biotech  Ltd.
(formerly  Net-Force  Systems Inc.) ("the  Company") as at December 31, 2003 and
2002,  and  the  related  consolidated   statements  of  stockholders'   equity,
operations and cash flows for the years then ended and the period from April 28,
2001  (inception)  to December  31, 2001.  These  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

In our opinion,  these consolidated  financial statements present fairly, in all
material  respects,  the  financial  position of the Company as at December  31,
2003,  and 2002 and the  results  of its  operations  and its cash flows for the
years then ended and the period from April 28, 2001  (inception) to December 31,
2001 in conformity with generally accepted  accounting  principles in the United
States of America.

(formerly Net-Force Systems Inc.)

Notes to Consolidated Financial Statements

December 31, 2003 and 2002
(Expressed in U.S. Dollars)
================================================================================


1.   Nature of Business and Continuation of Operation
- -----------------------------------------------------

     These  consolidated  financial  statements  presented  are those of Sinovac
     Biotech Ltd.,  formerly Net-Force Systems Inc.,  ("parent company") and its
     51%  owned  subsidiary   Sinovac  Biotech  Co.,  Ltd.   ("Sinovac  China").
     Collectively, they are referred to herein as "the Company".

     Sinovac China was  incorporated  under the laws of China on April 28, 2001.
     It is in the business of research and development,  production and sales of
     pharmaceutical products in China.

     On September  24, 2003,  Net-Force  Systems Inc.  ("Net-Force"),  a company
     incorporated on March 1, 1999 under the International Business Corporations
     Act No. 28 of 1982 of the laws of Antigua and Barbuda, entered into a Share
     Exchange  Agreement  ("Agreement")  with Sinovac China,  whereby  Net-Force
     issued 10,000,000 shares of its common stock in exchange for a 51% interest
     in Sinovac  China.  As part of the  agreement,  Net-Force  disposed  of its
     wholly  owned  subsidiary,  Net Force  Entertainment,  Inc.  and all of its
     assets and  liabilities to a company  controlled by its president and Chief
     Executive  Officer for $100 and then become a non-operating  shell company.
     Immediately  prior to the  Agreement,  Net-Force had  17,091,033  shares of
     common stock issued and  outstanding.  The acquisition was accounted for as
     recapitalization of Sinovac China because the shareholders of Sinovac China
     controlled  Net-Force after the  acquisition.  Sinovac China was treated as
     the  acquiring  entity  for  accounting  purposes  and  Net-Force  was  the
     surviving entity for legal purposes.  The combined company is considered to
     be a  continuation  of the  operations  of  Sinovac  China.  The issued and
     outstanding  common  stock of  Sinovac  China  prior to the  completion  of
     acquisition  was restated to reflect the 10,000,000  common stock issued by
     Net-Force.  Effective  on October 21, 2003,  Net-Force  changed its name to
     Sinovac Biotech Ltd. The Company has an office in Vancouver, Canada.

     Net-Force had no operations between May 1, 2003 and September 23, 2003.

2.   Significant Accounting Policies
- ------------------------------------

     (a)  Base of Presentation

          These  consolidated  financial  statements include the accounts of the
          parent  company  and its 51%  owned  subsidiary,  Sinovac  China.  All
          significant inter-company transactions have been eliminated.

     (b)  Use of Estimates

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

2.   Significant Accounting Policies (continued)
- ------------------------------------------------

     (c)  Cash and Cash Equivalents

          Cash equivalents usually consist of highly liquid investments that are
          readily  convertible  to cash with  maturities of three months or less
          when purchased.

     (d)  Inventories

          Inventories  are  stated  at the  lower of cost or  market  with  cost
          generally  determined on a first-in,  first-out  basis.  Cost includes
          direct material, direct labour and overheads.

     (e)  Property, plant and Equipment

          Property,   plant  and  equipment  are  recorded  at  cost,  including
          capitalized  interest  and  internal  engineering  costs.  Significant
          additions  and  improvements   are  capitalized,   while  repairs  and
          maintenance are charged to expenses as incurred.  Equipment  purchased
          for specific  research and  development  projects with no  alternative
          uses are  expensed.  Depreciation  of  property,  plant and  equipment
          generally  is computed  using the  straight-line  method  based on the
          estimated useful lives of the assets as follows:

          Land-use rights                             49 years
          Plant and building                          30 years
          Machinery and equipment                     8 - 10 years
          Motor vehicles                              5 years
          Office equipment and furniture              5 years
          Leasehold improvements                      Term of lease (5years)

     (f)  Licenses and Permits

          Licenses  and  permits,  in  relation to the  production  and sales of
          pharmaceutical  products in China,  are  amortized on a  straight-line
          basis over their  useful lives of ten (10) years.  Carrying  values of
          such assets are reviewed at least  annually by comparing  the carrying
          amounts to their estimated  undiscounted net future cash flows.  There
          were no impairment  adjustments  to the carrying value of the licenses
          and  permits for the years  ended  December  31, 2003 and 2002 and the
          period from April 28, 2001 (inception) to December 31, 2001.

     (g)  Impairment of Long-Lived Assets

          The Company has adopted  Statement of Financial  Accounting  Standards
          ("SFAS")  No.  144  "Accounting  for the  Impairment  or  Disposal  of
          Long-Lived Assets". Long-lived assets and intangible assets subject to
          amortization are reviewed for impairment whenever events or changes in
          circumstances indicate that the carrying value of the asset may not be
          recoverable  from the future,  undiscounted net cash flows expected to
          be generated by the asset. If the asset is not fully  recoverable,  an
          impairment  loss would be recognized  for the  difference  between the
          carrying  value of the asset and its  estimated  fair  value  based on
          discounted net future cash flows or quoted market  prices.  There were
          no impairment losses recognized in 2003, 2002 and 2001.

     (h)  Income Taxes

          The Company has adopted  Statement of Financial  Accounting  Standards
          ("SFAS") No. 109,  "Accounting  for Income Taxes",  which requires the
          Company  to  recognize  deferred  tax  liabilities  and assets for the
          expected  future tax  consequences of events that have been recognized
          in the  Company's  financial  statements  or  tax  returns  using  the
          liability  method.  Under this method,  deferred tax  liabilities  and
          assets are determined based on the temporary  differences  between the
          financial  statements  and tax bases of assets and  liabilities  using
          enacted tax rates in effect in the years in which the  differences are
          expected to reverse.

     (i)  Revenue Recognition

          Sales revenue is recognized when persuasive evidence of an arrangement
          exists, the price is fixed and final,  delivery has occurred and there
          is  reasonable  assurance of  collection  of the sales  proceeds.  The
          Company generally obtains purchase  authorizations  from its customers
          for a specified  amount of products at a specified price and considers
          delivery to have  occurred when the customer  takes  possession of the
          products.  The Company  provides its customers with a limited right of
          return.  Revenue is  recognized  upon delivery and a reserve for sales
          returns is recorded.  The Company has demonstrated the ability to make
          reasonable  and reliable  estimates of products  returns in accordance
          with SFAS No. 48, Revenue Recognition When Right of Return Exists.

     (j)  Advertising Expenses

          Advertising  costs are  expensed as incurred  and  included in selling
          expenses.  Approximated  advertising  costs are  $14,886,  $77,790 and
          $24,802 for the years ended  December 31, 2003 and 2002 and the period
          from April 28, 2001 (inception) to December 31, 2001, respectively.

     (k)  Research and Development

          Research and development  costs are charged to operations as incurred.
          Research and  development  costs are listed as a separate line item on
          the Company's statements of operations.

          Research  grants are taken into income as a reduction  of research and
          development   expenses  when  conditions  imposed  by  the  government
          authorities are fulfilled.

     (l)  Foreign Currency Transactions

          The parent company and its subsidiary,  Sinovac China,  maintain their
          accounting records in their functional  currencies,  i.e. U.S. dollars
          and  Renminbi  Yuan  respectively.   The  Company  translates  foreign
          currency  transactions  into its functional  currency in the following
          manner:

          At the transaction date, each asset, liability, revenue and expense is
          translated  into the  functional  currency by the use of the  exchange
          rate in effect at that  date.  At the  period  end,  foreign  currency
          monetary assets,  and liabilities are re-evaluated into the functional
          currency by using the  exchange  rate in effect at the  balance  sheet
          date. The resulting  foreign exchange gains and losses are included in
          operations.

     (m)  Foreign Currency Translations

          The assets and  liabilities of the foreign  subsidiary,  Sinovac China
          (whose functional currency is Renminbi Yuan), are translated into U.S.
          dollars at exchange rates in effect at the balance sheet date. Revenue
          and expenses are translated at average  exchange rate. Gain and losses
          from such  translations  are included in  stockholders'  equity,  as a
          component of other comprehensive income.

     (n)  Stock-based Compensation

          The  Company   adopted  the  fair  value  method  of  accounting   for
          stock-based  compensation  recommended  by of  Statement  of Financial
          Accounting  Standards No. 123 (SFAS 123),  "Accounting for Stock-based
          Compensation".  On November 1, 2003, the board of directors approved a
          stock option plan that is described more fully in Note 11. The Company
          did not grant  stock  options  for the  period  from  April  28,  2001
          (inception) to December 31, 2002.

     (o)  Comprehensive Income

          The  Company  has  adopted  SFAS  No.  130,  "Reporting  Comprehensive
          Income",  which  establishes  standards  for  reporting and display of
          comprehensive  income,  its components and accumulated  balances.  The
          Company  is   disclosing   this   information   on  its  Statement  of
          Stockholders'  Equity.  For the years ended December 31, 2003 and 2002
          and the period from April 28, 2001  (inception)  to December 31, 2001,
          the Company's comprehensive income consists of net earnings (loss) and
          foreign currency translation adjustments.

     (p)  Earnings (Loss) Per Share

          Basic earning (loss) per share is computed using the weighted  average
          number of shares  outstanding  during the period.  The Company adopted
          SFAS No. 128, "Earnings Per Share". Diluted loss per share is equal to
          the basic loss per share for the year ended  December 31, 2003 because
          common stock  equivalents  consisting of options to acquire  3,000,000
          common  stocks  that  are   outstanding   at  December  31,  2003  are
          anti-dilutive, however, they may be dilutive in future.

     (q)  Financial Instruments and Concentration of Credit Risks

          Fair value of financial  instruments  are made at a specific  point in
          time,  based on  relevant  information  about  financial  markets  and
          specific financial  instruments.  As these estimates are subjective in
          nature,  involving uncertainties and matters of significant judgement,
          they cannot be determined with  precision.  Changes in assumptions can
          significantly affect estimated fair values.

          The carrying value of cash and cash equivalents,  accounts receivable,
          loans payable,  accounts payable and accrued  liabilities  approximate
          their  fair  value   because  of  the   short-term   nature  of  these
          instruments.

          The Company is operating in China,  which may give rise to significant
          foreign currency risks from  fluctuations and the degree of volatility
          of foreign  exchange rates between US dollars and the Chinese currency
          RMB.  Financial  instruments that  potentially  subject the Company to
          concentration  of credit risks consist  principally  of cash and trade
          receivables,  the  balances  of which are  stated on the  consolidated
          balance  sheets.  The Company  places its cash in high credit  quality
          financial   institutions.   The  Company's   customers  are  primarily
          pharmaceutical and biotechnology companies. One customer accounted for
          15.83% of total  sales for the year ended  December  31,  2003 and two
          customers  accounted  for  41.42% of total  sales  for the year  ended
          December 31, 2002. Concentration of credit risks with respect to trade
          receivables  are limited to a degree due to the Company's large number
          of diverse customers in different  locations in China.  Ongoing credit
          evaluations  of customers'  financial  condition are performed and the
          Company maintains  provision for potential credit losses if necessary.
          The Company does not require  collateral or other  security to support
          financial  instruments  subject to credit  risks.  The  Company is not
          subject to significant interest risks.

     (r)  Accounting for Derivative Instruments and Hedging Activities

          The  Company  has  adopted  the  Statement  of  Financial   Accounting
          Standards No. 133 (SFAS 133),  Accounting for  Derivative  Instruments
          and Hedging  Activities,  which  requires  companies to recognize  all
          derivatives  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
          objective 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.

          The Company has not entered into derivative  contracts either to hedge
          existing  risks  or for  speculative  purposes.  The  option  of  this
          pronouncement  does not have an impact on its  consolidated  financial
          statements.

     (s)  New Accounting Pronouncements

          In January 2003, the Financial Accounting Standard Board released FASB
          Interpretation No. 46 ("FIN 46"),  "Consolidation of Variable Interest
          Entities." FIN 46 requires that all primary  beneficiaries of variable
          interest  entities  consolidate  that  entity.  FIN  46  is  effective
          immediately for variable  interest  entities created after January 31,
          2003 and to variable interest entities in which an enterprise  obtains
          an interest  after that date.  It applies in the first  fiscal year or
          interim  period  beginning  after June 15, 2003 to  variable  interest
          entities in which an enterprise holds a variable  interest it acquired
          before  February  1, 2003.  In  December  2003,  the FASB  published a
          revision to FIN 46 ("FIN 46R") to clarify  some of the  provisions  of
          the  interpretation  and to defer the effective date of implementation
          for certain entities.  Under the guidance of FIN 46R, entities that do
          not have  interests in  structures  that are  commonly  referred to as
          special  purpose  entities are required to apply the provisions of the
          interpretation in financial  statements for periods ending after March
          14, 2004. The Company did not create a variable  interest entity after
          January  31, 2003 and does not have a variable  interest  entity as of
          December 31, 2003.  The Company  expects that the full adoption of FIN
          46R does not have an impact on its  financial  position  or results of
          operations

- ------------------------------------------------

     (s)  New Accounting Pronouncements (continued)

          In May 2003, the FASB issued SFAS No. 149,  Amendment of Statement 133
          on  Derivative  Instruments  and  Hedging  Activities.  SFAS  No.  149
          addresses  certain  accounting  issues related to hedging activity and
          derivative  instruments  embedded in other contracts.  In general, the
          amendments  require  contracts with comparable  characteristics  to be
          accounted for similarly.  In addition,  SFAS No. 149 provides guidance
          as to when a financing component of a derivative must be given special
          reporting  treatment in the  statement of cash flows.  SFAS No. 149 is
          effective for contracts  entered into or modified after June 30, 2003.
          The adoption of SFAS No. 149 does not have an impact on the  Company's
          consolidated financial statements.

          In May 2003, the Financial  Accounting Standards Board (FASB) approved
          SFAS No.  150,  Accounting  for  Certain  Financial  Instruments  with
          Characteristics   of  Both  Liabilities  and  Equity.   SFAS  No.  150
          establishes  standards  for  how to  classify  and  measure  financial
          instruments with  characteristics  of both liabilities and equity.  It
          requires  financial  instruments  that  fall  within  its  scope to be
          classified  as  liabilities.  SFAS No. 150 is effective  for financial
          instruments  entered  into or  modified  after May 31,  2003 and,  for
          pre-existing  financial  instruments,  as of July 1, 2003. The Company
          does not have any financial  instruments  that fall under the guidance
          of SFAS No. 150 and, therefore,  the adoption does not have any effect
          on the Company's consolidated financial statements.

          In a December 11, 2003 speech at the  American  Institute of Certified
          Public  Accountants,  the Securities and Exchange  Commission  ("SEC")
          expressed that  rate-lock  commitments  represent  written put options
          and, therefore, be valued as a liability.  The SEC expressed that they
          expect  registrants to disclose the effect on the financial  statement
          of recognizing the rate-lock  commitments as written put options,  for
          quarters  commencing  after  March  15,  2004.  Additionally,  the SEC
          recently issued Staff  Accounting  Bulletin (SAB) No. 105. SAB No. 105
          clarifies  the SEC's  position  that the  inclusion of cash flows from
          servicing or ancillary  income in the  determination of the fair value
          of interest rate lock commitments is not appropriate.  The adoption of
          SAF No.  105 will not have an  impact  on the  Company's  consolidated
          financial statements.

     =======================================================================

     (a)  In March 2003,  Sinovac China acquired the Influenza  Virus HA Vaccine
          drug  license  from  a  company   called   Tangshan  Yian   Biological
          Engineering Co., Ltd. ("Tangshan Yian") at the vendor's cost. Tangshan
          Yian  owned an 18.75%  interest  in  Sinovac  China and there were two
          common directors  between the companies at the time of the transaction
          (Also see Note 15). Sinovac China is applying for a production  permit
          for  this  pharmaceutical  product.  The cost of the  license  will be
          amortized  based  on an  estimated  useful  life  of  ten  (10)  years
          commencing with the production of the drug, which is expected to be in
          early 2005.

     (b)  In April 2002,  Sinovac China acquired the  Recombinant  Hepatitis A&B
          drug license from a company called Beijing Keding Investment Co., Ltd.
          ("Beijing  Keding") by issuing  shares  equal to a 10.71%  interest in
          Sinovac China and paying $18,116  (RMB150,000) in cash. Beijing Keding
          is owned by a director,  president and three other senior  officers of
          Sinovac China.  As at December 31, 2003,  $10,487  remained unpaid and
          was recorded in due to related  parties (see Note 10a).  Sinovac China
          is applying for a production permit for this  pharmaceutical  product.
          The cost of the license will be amortized based on an estimated useful
          life of ten (10) years  commencing  with the  production  of the drug,
          which is expected to be in mid-2004.  The drug license was recorded at
          the vendor's cost.

     (c)  The Inactive Hepatitis A drug license was contributed by Tangshan Yian
          in 2001 as its capital contribution to Sinovac China. The drug license
          was recorded at $1,941,879, which was the transferor's cost.

6.   Licenses and Permits (continued)
- -------------------------------------

     (d)  Amortization  expense  for the  licenses  and  permits  was  $194,343,
          $97,094 and nil for the years ended December 31, 2003 and 2002 and the
          period  from  April  28,  2001   (inception)   to  December  31,  2001
          respectively.

          The estimated  amortization  expenses for each of the five  succeeding
          fiscal years are as follows:

                    2004                        $220,000
                    2005                        $283,000
                    2006                        $283,000
                    2007                        $283,000
                    2008                        $283,000

          The above amortization expense forecast is an estimate. Actual amounts
          of  amortization  expense  may differ  from  estimated  amounts due to
          additional intangible asset acquisitions,  changes in foreign currency
          exchange   rates,   impairment  of  intangible   assets,   accelerated
          amortization of licenses and permits, and other events.

     Bank loan in the amount of $603,865 (RMB 5,000,000) is bearing  interest at
     5.49% per annum. The interest is payable quarterly and the principal is due
     on December 19, 2005.


9.   Income Taxes
- -----------------

     Sinovac China is subject to income taxes in China on its taxable  income as
     reported in its  statutory  accounts at a tax rate in  accordance  with the
     relevant income tax laws applicable to sino-foreign investment enterprises.
     Pursuant to the same income tax laws,  it is exempt from income tax for two
     years  starting  from  its  first  profit-making  year  followed  by a  15%
     corporation  income tax rate for the next three years.  No income taxes was
     charged on Sinovac China for each of the two years ended  December 31, 2003
     and the period from April 28, 2001  (inception)  to December 31, 2001.  The
     parent company is not subject to Income taxes.

     The tax effect of  temporary  differences  that give rise to the  Company's
     deferred tax asset (liability) are as follow:



     ---------------------------------------------------------------------------------------
                                                          2003          2002            2001
     ---------------------------------------------------------------------------------------

                                                                       
     Tax losses carried forward                   $    139,000   $    100,000   $     12,000
     Excess of tax cost over the net book value
     of the certain long-lived assets                  711,000        753,000        611,000
     Less: valuation allowance                        (850,000)      (853,000)      (623,000)
     ---------------------------------------------------------------------------------------

     =======================================================================================


     The potential  tax benefits  arising from the losses have not been recorded
     in the financial statements.  The Company evaluates its valuation allowance
     requirements on an annual basis based on projected future operations.  When
     circumstances  change and this  causes a change in  management's  judgement
     about the realizability of deferred tax assets, the impact of the change on
     the valuation allowance is generally reflected in current income.
