D.   Risk Factors
     ------------

RISKS RELATED TO SINOVAC'S FINANCIAL CONDITION
- ----------------------------------------------

The Company has a history of losses and may never achieve profitability.
- ------------------------------------------------------------------------


Sinovac incurred net losses of $4,667,000 for the fiscal year ended December 31,
2004, and $872,000 in 2003. At December 31, 2004, the Company had an accumulated
deficit of $6,155,425.  To become profitable the Company must increase its sales
and continue to limit  operating  expenses  growth.  If sales do not grow, or if
expenses  grow  excessively,  the Company may not be able to achieve or maintain
profitability in the future.


Sinovac will need additional capital to continue  development of its new vaccine
- --------------------------------------------------------------------------------
products and to market existing vaccine products on a large scale.
- ------------------------------------------------------------------

The  Company  will need to raise  further  funds  from the  capital  markets  to
continue the development and  commercialization of its products.  This may delay
progress in product  development  or market.  Although  the Company has adequate
near-term  cash  requirements,  it may  need  to  undertake  significant  future
financings  to  complete  clinical  trials  for  new  vaccines,  as  well  as to
facilitate  large-scale  commercial rollout of new products.  In the future, the
Company may  require  funds in excess of its  existing  cash  resources  for the
following  reasons:  to proceed with the development of other vaccine  products,
including clinical testing relating to new products; to develop or acquire other
technologies or other lines of business;  to establish and expand  manufacturing
capabilities;  and to finance general and administrative and research activities
that are not  related  to  specific  products  under  development.  In the past,
Sinovac funded most of its development and other costs through equity financing.
The Company anticipates the need for additional  funding,  and because operating
and capital resources are insufficient to meet future requirements, will have to
raise  additional  funds in the near  future to  continue  the  development  and






                                        4



commercialization  of its products.  Unforeseen  problems,  including materially
negative  developments  in clinical  trials or in general  economic  conditions,
could interfere with the Company's ability to raise additional equity capital or
materially  adversely affect the terms upon which such funding is available.  It
is possible  that the  Company  will be unable to obtain  sufficient  additional
funding when needed. If the Company were unable to obtain additional  funding as
and when needed, it could be forced to delay the progress of certain development
efforts.  Such a scenario  poses risks.  For example,  the Company's  ability to
bring a product to market  and obtain  revenues  could be  delayed,  competitors
could  develop  products  sooner,  and/or  Sinovac could be forced to relinquish
rights to technologies, products or potential products.

The Company may have to rely on new equity financing to raise additional capital
- --------------------------------------------------------------------------------
and this would dilute stockholders' holdings
- --------------------------------------------

If Sinovac  raises funds through  equity  financing to meet the needs  discussed
above, it will have a dilutive  effect on existing  holders of Company shares by
reducing  their  percentage of ownership.  The shares may be sold at a time when
the market  price is low because the Company  needs the funds.  This will dilute
existing  holders more than if the stock price was higher.  In addition,  equity
financings  normally  involve  shares sold at a discount  to the current  market
price.

RISKS RELATED TO SINOVAC'S TECHNOLOGIES
- ---------------------------------------

Sinovac  will  only  receive  revenues  from its  products  that  have  received
- --------------------------------------------------------------------------------
regulatory approval to sell. Many factors impact the Company's ability to obtain
- --------------------------------------------------------------------------------
approvals for its products.
- ---------------------------

There can be no assurance  that all of the  clinical  trials  pertaining  to the
Company'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  authorities  if  unforeseen  health  risks  become an issue with the
participants of clinical trials.  In addition,  pre-clinical and clinical trials
of  the  Company's  products,   and  the  manufacturing  and  marketing  of  its
technologies,  are  subject to  extensive,  costly and  rigorous  regulation  by
governmental authorities. The process of obtaining required regulatory approvals
from the China State Food and Drug Administration  ("SFDA") and other regulatory
authorities  often takes many years,  is  expensive  and can vary  significantly
based on the type,  complexity and novelty of the product candidates.  For these
reasons,  it is possible the Company will never receive approval for one or more
product candidates in the future.

Delays in obtaining SFDA or foreign  approvals for the Company's  products could
result in  substantial  additional  costs and  adversely  affect its  ability to
compete with other companies.  If regulatory approval is ultimately granted, the
approval  may place  limitations  on the intended use of the product the Company
wants to commercialize, and may place restrictions on product marketing.






                                        5



Due to legal and  factual  uncertainties  regarding  the  scope  and  protection
- --------------------------------------------------------------------------------
afforded  by  patents  and  other  proprietary  rights,  Sinovac  may  not  have
- --------------------------------------------------------------------------------
meaningful protection from competition.
- ---------------------------------------

Sinovac's  long-term  success  will  substantially  depend  upon its  ability to
protect proprietary technologies from infringement, misappropriation, discovery,
and  duplication,  and avoid  infringing the proprietary  rights of others.  The
Company relies on  trademarks,  trade  secrets,  confidentiality  procedures and
contractual   provisions  and  government   intellectual   property   protection
assurances to protect its  intellectual  property.  The  Company's  intellectual
property  rights,  and the  intellectual  property rights of  biotechnology  and
pharmaceutical  companies in general,  are highly  uncertain and include complex
legal and factual  issues.  Because of this,  any future  intellectual  property
rights  applications  Sinovac  undertakes  with  respect  to its  SARS  vaccine,
combination hepatitis A and B vaccine, influenza vaccine, or potential avian flu
vaccine may not be granted.  These  uncertainties  also mean that any patents or
intellectual  property rights that The Company owns or will obtain in the future
could be subject to challenge,  and even if not challenged,  may not provide The
Company with meaningful protection from competition.  Due to Sinovac's financial
uncertainties,  it may not possess the financial  resources necessary to enforce
its patents and/or intellectual  property rights.  Intellectual  property rights
already  provided to the Company or pending  applications  may become subject to
dispute, and any dispute could be resolved against the Company. .

Because a substantial number of patents and/or intellectual property rights have
been issued in the field of biopharmaceuticals and because such positions can be
highly uncertain and frequently involve complex legal and factual questions, the
breadth of claims  obtained  in any  application  or the  enforceability  of the
Company's  patents  and/or  intellectual  property  rights  cannot be predicted.
Consequently, the Company does not know whether its intellectual property rights
or future patent applications will result in the issuance of patents or, whether
these patents will be subject to further  proceedings  limiting their scope,  or
provide significant  proprietary protection or competitive advantage,  or become
circumvented or invalidated.

Also,  because of these legal and  factual  uncertainties,  and because  pending
patent and/or  intellectual  property right applications are held in secrecy for
varying  periods  depending on the  particular  country,  even after  reasonable
investigation  the Company may not know with certainty whether any products that
it  (or a  licensee)  may  develop  will  infringe  upon  any  patent  or  other
intellectual property right of a third party.

The  Company  could be subject to costly and  time-consuming  product  liability
- --------------------------------------------------------------------------------
actions.
- --------

Sinovac manufactures vaccines that are injected into patients to protect against
infectious  illnesses and, as a result, the Company may in the future be subject
to product liability  lawsuits.  Any product liability claim brought against the
Company, with or without merit, could have a material adverse effect on Sinovac.
Even  a  meritless  or  unsuccessful  product  liability  claim  could  be  time
consuming,   expensive  to  defend,   and  could  result  in  the  diversion  of
management's  attention  from managing the Company's  core business or result in
associated negative publicity.






                                        6



RISKS RELATED TO MARKETING OF SINOVAC'S POTENTIAL PRODUCTS
- ----------------------------------------------------------

Because the Company faces significant  international  competition from companies
- --------------------------------------------------------------------------------
with greater resources, Sinovac may be unable to compete effectively.
- ---------------------------------------------------------------------

Competition from other biomedical companies in the global vaccine marketplace is
a risk that Sinovac faces. 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 flu vaccines is a distinct possibility.

Changes  in the  policies  of the  Communist  Government  of China or  political
- --------------------------------------------------------------------------------
instability  could delay the further  liberalization  of the Chinese economy and
- --------------------------------------------------------------------------------
adversely affect economic conditions in China generally,  which could impact the
- --------------------------------------------------------------------------------
Company's business and prospects.
- ---------------------------------

Sinovac is currently  targeting its products for distribution and sale in China,
which represents the domestic market, and in Southeast Asia and other developing
countries.  Because  of the  Company's  concentration  in China,  its assets and
business  ventures are  susceptible  to any  reversals  of China's  longstanding
policies on economic reform or changes in its health  policies.  Sinovac's sales
may be  adversely  impacted  by any  changes in  government,  such as changes in
leadership or social disruption which may result in restrictions being placed on
import and export of foreign goods,  acceptance into the local market of foreign
health  products,  advertising of foreign goods and public attitude  towards the
Company's vaccines.

The  economic  environment,  pricing  pressure  and rising  wages in China could
- --------------------------------------------------------------------------------
negatively impact Sinovac's revenues and operating results.
- -----------------------------------------------------------

The Company's  ability to maintain or increase  pricing is restricted as clients
often expect they will receive volume  discounts or special pricing  incentives.
Existing and new customers are also increasingly  using third-party  consultants
with broad market  knowledge to assist them in  negotiating  contractual  terms.
Large U.S.  multinational  companies are establishing larger offshore operations
in China,  resulting in wage pressures for Chinese companies.  Pricing pressures
from the Company's clients, wage pressures in China and an increase in sales and
marketing expenditures may have a negative impact on operating results.

Sinovac is  investing  substantial  cash assets in new  facilities  and physical
- --------------------------------------------------------------------------------
infrastructure,  and  profitability  could be reduced if business  does not grow
- --------------------------------------------------------------------------------
proportionately.
- ----------------

Sinovac intends to invest substantial cash assets in new facilities and physical
infrastructure  in 2005.  The Company  may  encounter  cost  overruns or project
delays in connection  with new  facilities  and physical  infrastructure.  These
expansions may increase The Company's  fixed costs. If Sinovac is unable to grow
its business and revenues proportionately, profitability will be reduced.






                                        7



RISKS RELATED TO MANAGEMENT
- ---------------------------

There are  limitations on the  enforcement of U.S. laws against  Sinovac Biotech
- --------------------------------------------------------------------------------
Ltd., its management, and others.
- ---------------------------------

Sinovac  was  incorporated  on March 1,  1999,  under the laws of  Antigua.  The
majority  of the Board of  Directors  members  are not  residents  of the United
States.  All  Company  assets  are  located  outside  of the  United  States and
substantially  all of the  directors'  assets are located  outside of the United
States.  As a result,  it may not be possible for investors to effect service of
process  within the United States upon a majority of the Company's  directors or
upon the Company,  or enforce  judgments  obtained in U.S. courts based on civil
liability provisions of the U.S. securities laws against the Company in Antigua.
Awards of punitive  damages in actions brought in the United States or elsewhere
may not be enforceable in Antigua.  In addition,  actions  brought in a court in
Antigua  against  the  Company or members of its Board of  Directors  to enforce
liabilities  based on U.S.  federal  securities  laws may be  subject to certain
restrictions;  in particular, a court in Antigua may not award punitive damages.
The United  States and  Antigua do not  currently  have a treaty  providing  for
recognition  and  enforcement  of  judgments  in civil and  commercial  matters.
Therefore,  a final judgment for the payment of money rendered by any federal or
state  court in the  United  States  based on civil  liability,  whether  or not
predicated  solely upon United  States  federal  securities  laws,  would not be
automatically enforceable in Antigua.

Sinovac relies heavily on key management  personnel and the degree of success of
- --------------------------------------------------------------------------------
the Company's  business may be dependant on the fulfillment of their  employment
- --------------------------------------------------------------------------------
obligations.
- ------------

Sinovac's  success is very dependant on the talents,  capabilities,  efforts and
commitment of certain key members of its management team, such as President, Dr.
Yin, Professor Pan, Chairman of the Company's majority owned subsidiary, Sinovac
Beijing,  of which Sinovac owns 71.56%. The loss of the service of these members
of management could have a material adverse effect on the Company.

RISKS RELATED TO THE MARKET FOR SINOVAC'S COMMON STOCK
- ------------------------------------------------------

The price of the Company's common stock may be volatile.
- --------------------------------------------------------

There may be wide  fluctuation  in the price of Sinovac's  common  stock.  These
fluctuations  may be caused  by  several  factors  including:  announcements  of
research activities and technology innovations or new products by the Company or
its  competitors;  changes in market  valuation  of  companies  in the  industry
generally; variations in operating results; changes in governmental regulations;
developments in patent and other  proprietary  rights;  public concern as to the
safety of drugs or  treatments  developed  by the Company or others;  results of
clinical trials of Sinovac's products or competitors'  products;  and regulatory
action or inaction on the Company's products or competitors' products. From time
to  time,  the  Company  may hire  companies  to  assist  in  pursuing  investor
relations'  strategies  to  generate  increased  volumes  of  investment  in the
Company's  common stock.  Such  activities  may result,  among other things,  in
causing the price of Sinovac's  common stock to increase on a short-term  basis.
Furthermore,  the stock market  generally and the market for stocks of companies
with lower market capitalizations and small  biopharmaceutical  companies,  like






                                        8



Sinovac,  have from time to time experienced,  and likely will again experience,
significant  price and volume  fluctuations  that are unrelated to the operating
performance of a particular company.

Sinovac may acquire  technologies or companies in the future, which could result
- --------------------------------------------------------------------------------
in the dilution of the Company's  stockholders  and  disruption of its business,
- --------------------------------------------------------------------------------
and reduced revenues.
- ---------------------

Sinovac is continually evaluating business alliances and external investments in
technologies  related to its business.  Acquisitions of companies,  divisions of
companies,  businesses,  or products entail  numerous risks,  any of which could
materially harm the Company's business in several ways, including:  diversion of
management's  attention  from their core business  objectives and other business
concerns;  failure to integrate efficiently  businesses or technologies acquired
in the future with pre-existing business or technologies;  potential loss of key
employees from either pre-existing  business or the acquired business;  dilution
of  existing  stockholders  as  a  result  of  issuing  equity  securities;  and
assumption of liabilities of the acquired company. Some or all of these problems
may result from future acquisitions or investments. Furthermore, the Company may
not realize any value from such acquisitions or investments.

Sinovac's stock may be deemed to be "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
$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  $2,000,000  (if the  issuer has been in
continuous  operation for at least three years) or $5,000,000  (if in continuous
operation  for less than three  years),  or with  average  revenues of less than
$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






                                        9



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.


ITEM 4 - INFORMATION ON THE COMPANY
- -----------------------------------


A.   History and Development of the Company
     --------------------------------------

Incorporation
- -------------

Sinovac  Biotech Ltd. (the "Company") was  incorporated on March 1, 1999,  under
the laws of  Antigua  under  the  name  "Net  Force  Systems  Inc."  By  special
resolution of the Company dated October 8, 2003, the Company changed its name to
"Sinovac Biotech Ltd."

Corporate Information
- ---------------------

The  Company's  business  address  and  executive  offices are located at No. 39
Shangdi Xi Road,  Haidian District,  Beijing,  P.R. China 100085.  The Company's
telephone   number  is   86-10-82890088   and  the   Company's   fax  number  is
86-10-62966910.  The  Company's  agent for  service in Canada is Devlin  Jensen,
Barristers  &  Solicitors,  who are  located at Suite  2550,  555 West  Hastings
Street, Vancouver,  British Columbia, V6B 4N5, and who can be contacted at (604)
684-2550 or via facsimile at (604) 684-0916.

On September  24, 2003,  the Company and Ms. Lily Wang, a natural  person of the
United  States,  entered  into a share  purchase  agreement  whereby the Company
acquired a 51%  ownership  interest  in Sinovac  Biotech  Co.,  Ltd.,  a company
organized  under the laws of the  People's  Republic of China,  from Ms. Wang in
exchange for the issuance of  10,000,000  newly issued shares of common stock of
the  Company  at a state  value of $0.60  per  share  for a total of  $6,000,000
constituting  approximately 37% of the Company's  outstanding capital stock on a
fully-diluted basis at that time.

On January 26, 2004, the Company entered into a formal share purchase  agreement
(the "Share  Purchase  Agreement") to acquire 100% of the issued and outstanding
shares of Tangshan Yian Biological  Engineering Co., Ltd.  ("Tangshan  Yian"), a
corporation  organized under the laws of the People's Republic of China, through
the issuance of 3,500,000  shares of common stock of the Company plus $2,200,000
in cash,  which will be payable by the Company within 12 months from the date of
entering  into the  Share  Purchase  Agreement,  to Mr. He Ping  Wang,  the sole
shareholder of Tangshan Yian and also a director of the Company.  At the time of
completion of the Share Purchase Agreement,  Mr. He Ping Wang held approximately
11.45% of the Company's outstanding shares of common stock. On January 30, 2004,
all of the  terms  and  conditions  of the  Share  Purchase  Agreement  had been
satisfied and the acquisition of Tangshan Yian by the Company was completed.


Reserves
- --------

Pursuant to Chinese  company law applicable to foreign investment companies, the
Company's  subsidiaries,  Sinovac Beijing  and  Tangshan Yian,  are  required to






                                       10



maintain dedicated  reserves,  which include a general reserve and an enterprise
expansion reserve.  The  dedicated  reserves  are  to  be  appropriated from net
income after taxes, determined under the relevant Chinese accounting regulations
at a rate determined by the board of  directors  of the respective subsidiaries,
and recorded as a component of shareholders' equity.   Except  for the reduction
for losses incurred, any other usage should not result  in this  reserve balance
falling below  25% of  the  registered capital.  The dedicated  reserves are not
distributable other than upon liquidation.

For the year ended December 31, 2004, Sinovac Beijing  appropriated  10% of  its
after-tax profit, determined under the relevant Chinese accounting  regulations,
to each of the general reserve and the enterprise expansion reserve.  As Sinovac
Beijing recorded  a  loss  for the  year  ended  December 31, 2003  and 2002, no
appropriation to the dedicated reserves was made.

Pursuant  to  the  same  Chinese  company  law,  the  Company's subsidiaries are
required to transfer, at the discretion of  its board  of directors,  a  certain
amount of its annual  net income  after taxes as  determined under  the relevant
Chinese accounting regulations to a staff welfare and bonus  fund.  For the year
ended December 31, 2004,  the board  of  directors  of Sinovac  Beijing approved
$49,901 (RMB 413,183) for contribution to such fund which shall  be utilized for
collective staff benefits  such  as  building of staff  quarters or housing.  As
Sinovac Beijing recorded a net  loss  for  the  years end  December 31, 2003 and
2002, no  appropriation  to the staff  welfare  and  bonus  fund  was made.  The
amounts  appropriated  to  staff  welfare  and  bonus  fund were charged against
income and the  related  provisions were reflected as accrued liabilities in the
consolidated balance sheets.

Tangshan  Yian  recorded a  net  loss  for each of the three years in the period
ended December 31, 2004, so no appropriation to the dedicated reserves and staff
welfare and bonus fund was made.

Dividends declared by the Company's subsidiaries  are based on the distributable
profits as reported in their statutory financial statements.  As of December 31,
2004, dividends payable of $470,301 represent a  minority  interest in the share
of dividends declared by Sinovac Beijing.


Legal Proceedings
- -----------------

There are  currently no legal  proceedings  involving  Sinovac  Biotech Ltd. The
Company is not aware of any proceedings  being  contemplated by any governmental
authority.


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

Sinovac  specializes  in the  research,  development  and  commercialization  of
vaccines for infectious  diseases such as hepatitis A,  hepatitis B,  influenza,
Avian Flu Influenza and Severe Acute Respiratory Syndrome ("SARS").  The Company
aspires to become a leader in China's  biotech  industry.  Working  closely with
Chinese  public  health  agencies,  the  Company  focuses on  manufacturing  and
marketing  human-use  vaccines  and  related  products,  as  well  as  providing
technical and consulting services.  Sinovac is the first company in the world to
have been  granted  permission  to  conduct  human  clinical  trials  for a SARS
vaccine.







                                       11



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


As of December 31, 2004, the Company had $2,605,051 in cash and cash equivalents
and a positive working capital position of $1,814,611.



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


The overall  strategic mission of the Company is to become a world leader in the
research and development,  manufacturing and  commercialization  of vaccines for
epidemic viruses such as hepatitis and 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 objectives for 2005:

o    Increase  hepatitis A vaccine  (Healive(TM))  sales and revenues;  initiate
     sales of it's combined hepatitis A / B vaccine  (Bilive(TM));  and sales of
     its  influenza  flu vaccine  (Anflu(TM)).  To  accomplish  this  objective,
     Sinovac will:

     >    Expand the size of its sales force and conduct sales training

     >    Enhance brand  awareness  through  Chinese  media (news,  professional
          publications, and advertising)

     >    Conduct  and  participate  in  promotional  activities   (conferences,
          seminars, VIP visits to Company facilities)

o    Commence sales of Bilive(TM) in China (the SFDA approved Bilive(TM) January
     7, 2005)

o    Gain SFDA approval for Anflu(TM)  production facility and commence sales in
     China

o    Complete  the  Summary  Report on Phase I clinical  trial on SARS  vaccine;
     entering  Phase II clinical  trials will depend on the SFDA's  approval and
     requirements statement

o    Continue new vaccine products  development,  including an avian flu vaccine
     with the China Centre of Disease Control and Prevention ("China CDC")

o    Register and license  Healive(TM),  Bilive(TM)  and  Anflu(TM)  for sale in
     other developing countries

o    Forge international strategic partnerships to open overseas markets

o    Explore and develop domestic and international R&D and marketing agreements






                                       12



o    Explore acquisition opportunities

     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  and training a sales  organization  for 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.  These distributors have over 10 years experience in
commercialization and registration of vaccines and other pharmaceuticals through
established governmental relationships and local sales networks.

The second prong of the Company's marketing strategy contains a contingency plan
that  goes into  effect  once the  Company  creates a  blockbuster  vaccine  for
defeating emerging viruses such as SARS or the Avian Flu. The Company believes a
"first to market"  advantage  opens doors to  international  markets.  In such a
scenario, the Company intends to enter the international market with a worldwide
network  of   professional   sales   teams  and  sales   networks,   a  reliable
customer-credit management system, and an efficient logistics system.


Description of the Business
- ---------------------------

     General
     -------

The Company  specializes in the research,  development,  commercialization,  and
sales of vaccines for  infectious  diseases  such as  hepatitis A,  hepatitis B,
influenza, Avian Flu and SARS. The Company aspires to become a leader in China's
biotech  industry.  Working  closely with Chinese  public health  agencies,  the
Company focuses on manufacturing  and marketing  human-use  vaccines and related
products, as well as providing technical and consulting services. The Company is
the first  company  in the  world to have been  granted  permission  to  conduct
clinical trials for a SARS vaccine.


The Company's hepatitis A vaccine, Healive(TM), is currently experiencing strong
sales growth in China.  The Company sold 1,002,000 doses of Healive(TM) in 2004,
while in 2003 the Company sold 433,000  doses.  Sales  revenues in 2004 totalled
approximately  $6.5  million,  an  increase  of more than  127% over 2003  sales
revenues of $2.8 million.

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

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

Although  `virus' and  `vaccine'  are common terms that most people are familiar
with, several  variations of these terms exist. To ensure a clear  understanding
of the Company's  business and market,  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 on the aggressiveness
of the virus.

Some viruses will mutate or change  vital  characteristics  as they migrate to a
new host cell.  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,  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  requires  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, e.g., water 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.

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

The  consequences  for humans are physical,  emotional and of course  financial.
Influenza,  hepatitis and, more recently, SARS have all had a significant affect
on humans.

Hepatitis B causes 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 countries  acknowledge that
prevention by mass vaccination is more cost effective than a cure.

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

          Recurring Epidemic 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 eyes  and  skin)  and  fever.  Hepatitis  A will  leave a  person
incapacitated or weakened for a long time, as much as several weeks or 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.







                                       15



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

Hepatitis  B is one of the major  diseases  for  humans  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  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  BiliveTM  product can be priced to support  such
international programs and still provide significant net profit.

     Influenza
     ---------


Influenza  (commonly called "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.







                                       16



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  (AnfluTM)  vaccine in time to
begin sales during the 2005-2006 flu season.

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

     SARS
     ----

The SARS epidemic has intensified 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  prepared for the seriously  negative financial
impact that SARS has 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.






                                       17



     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
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  occurred  in
Vietnam  and  Thailand's  poultry  industries,  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 persons.

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.







                                       18



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

     HealiveTM
     ---------

Healive(TM)  is the first,  and to date,  only  inactivated  hepatitis A vaccine
developed in China.  In 1984,  Sinovac's  President  and CEO,  Mr.  Weidong Yin,
successfully isolated the TZ84 virus strain. Healive(TM) took nearly 10 years to
develop  and  gained  the New  Drug  Certificate  from  the  SFDA in  1999.  The
manufacturing  facility  was  designed by and  equipped by  reputable,  European
companies  and  certified  by the  China  State  Food  and  Drug  Administration
("SFDA"). Sales began in 2002.

Product testing research demonstrated the effects of Healive(TM) vaccinations on
children have excellent  immunogenicity,  slight reaction to the inoculation and
the same safety profile as inactivated  vaccines  manufactured by  international
companies.

Healive is produced by the Company's  71.56% owned  subsidiary,  Sinovac Biotech
Co., Ltd. ("Sinovac  Beijing"),  a company organized pursuant to the laws of the
People's Republic of China.

     BiliveTM
     --------

Bilive(TM) is the first, and currently only,  combined  inactivated  hepatitis A
and B vaccine developed by Chinese scientists. The R&D and clinical trial period
for  Bilive(TM)  was  impressive;  beginning at the end of 1999 and completed in
2003.  The SFDA gave its final approval for marketing and sales of Bilive(TM) on
January 7, 2005.

The SFDA  also  issued a  production  license  for  Bilive(TM)  and sales of the
vaccine in China will begin in 2005.  Bilive(TM)  vaccine has only one  directly
competing product in the world, GlaxoSmithKline's Twinrix(TM),  however only its
adult dosage vaccine is registered with the Chinese government.  Furthermore, it
is very  expensive with only a few thousand sales recorded after its launch into
the market.

Sinovac  used  its  proprietary  hepatitis  A  vaccine  in  combination  with  a
genetically  engineered  hepatitis  B vaccine to develop the  combined  vaccine.
Bilive(TM) is a combined vaccine formulated by purified inactivated  hepatitis A
virus antigen and recombinant (yeast) hepatitis B surface (HBsAg), absorbed into
aluminum  hydroxide.  Bilive(TM)  induces the body's  immune  system to generate
antibodies as a reaction against hepatitis A and hepatitis B viruses.  Hepatitis
B is a powerful disease that continues to be a serious global health concern.

The standard,  primary Bilive(TM)  vaccination schedule consists of three doses.
The second dose is  administered  one month after the first,  and the third dose
six months after the first.  Booster  vaccinations  are  recommended  five years
after the initial immunization.







                                       19



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
hepatitis A and hepatitis B infection.

Bilive(TM)  adult is suitable for use in non-immune  adults and  adolescents  16
years  of age  and  older,  who  are at  risk of  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,  homosexuals  and  bisexuals,
hemophiliacs who receive  therapeutic  blood products,  persons with nephropathy
who receive  dialysis  treatment,  and those persons who receive long term blood
dialysis.

Bilive(TM) 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.

     AnfluTM
     -------

Sinovac  began split flu vaccine  research and  development  in 2001,  completed
clinical trials in early 2004, and filed its New Drug  Application with the SFDA
in June  2004.  Quite  significantly,  the total  time to market  for  Sinovac's
products have been consistently reduced,  from ten years for HealiveTM,  to just
over four years for BiliveTM, to just under four years for AnfluTM.

The  Company  received  a New Drug  Certificate  from the SFDA for its split flu
vaccine  (AnfluTM) on February 25, 2005. The AnfluTM  production line is located
in Beijing and nearing  completion.  The  Company  believes it will  receive GMP
certification  for  the  production  line  in time to  begin  sales  during  the
2005-2006 flu season.

AnfluTM is safe for  children  and the  elderly.  Demand is  expected  to exceed
Sinovac's  production  capability  as demand in China for flu  vaccines  largely
exceeds total supply. As such, the Company intends to build another, much larger
AnfluTM vaccine production facility if financing is obtained.

     SARS
     ----


On January 19, 2004, the SFDA authorized the Company's  operating  subsidiary in
Beijing,  Sinovac  Biotech  Co., Ltd. ("Sinovac Beijing")  to  conduct a phase I
clinical  test  of  its  potential  SARS  vaccine.  Sinovac Beijing is the first
institute  approved by the SFDA to  conduct  human  clinical  trials  of  a SARS
vaccine.


Thirty-six healthy volunteers between the ages of 21 and 40 years were selected,
then divided into four groups for clinical  testing.  Twenty-four  subjects (two
groups of 12) received the vaccine in two dosage strengths,  while twelve others
(two  groups  of  six)  received  a  placebo.  Neither  the  volunteers  nor the
administering  doctors were informed of whether the injection was a vaccine or a
placebo. Each subject received two inoculations: the first being administered on
day zero, the second being administered 28 days later.







                                       20



The first  volunteers  received their injection on May 22, 2004. By September 1,
2004 all 36 subjects  participating  in the trial had been  vaccinated  with two
doses of either the SARS vaccine or the placebo. Professor Lin Jiangtao, head of
the Respiratory  Medical  Department at the China-Japan  Friendship  Hospital in
Beijing, led the trial.

The independent  result of the 56-day observation was submitted to the SFDA upon
completion.  China's Ministry of Science and Technology,  the Ministry of Health
and the SFDA  jointly  announced on December 5, 2004 that the phase I human test
of a SARS vaccine,  independently  developed by Chinese scientists,  proved safe
and effective in preliminary tests. This event marked China as the first country
in the world to complete a phase I clinical test of a SARS vaccine. According to
phase  I  clinical  trial  protocol,   the  trial  concluded  when  the  210-day
observation of all subjects from their first  inoculation  was  satisfied.  This
occurred in March 2005. The Company is currently conducting testing and analysis
on blood samples  collected from each volunteer  expect that the results will be
available in mid 2005.

     Avian Flu - Pandemic Influenza Vaccine (H5N1)
     ---------------------------------------------

The  National  Institute  for  Biological  Standards  and  Control,  arld Health
Organization (WHO) influenza laboratory began providing the reverse generic bird
flu virus  strain  in early  2004 to  vaccine  makers  around  the world for the
purpose of  developing  a viable  vaccine.  Sinovac  received the virus in March
2004.

Sinovac  signed an avian flu  vaccine  co-development  agreement  with the China
Centre of Disease Control and Prevention  ("China CDC").  Under the terms of the
agreement,  the  Company  will  apply for the New Drug  Certificate,  production
license, and patents. As a result, Sinovac will own all commercial rights.

Pursuant to the agreement,  the China CDC is  responsible  for  surveillance  of
influenza prevalence, molecular epidemiology study of the virus strain, guidance
and establishment of avian flu vaccine development strategies,  participation in
avian flu vaccine  research  and  development,  and the design of the  technical
process. Furthermore, the China CDC is responsible for conducting several tests,
including  genome analysis on the virus strains used in the vaccine research and
development,  antigen  analysis  and  immunization  protection  analysis,  among
others. Lastly, the China CDC is responsible for providing guidance on the scope
of use, storage, and the evaluation of the protection of the vaccine. Sinovac is
responsible  for  avian  flu  vaccine  research  and  development  based  on the
established technical platform, as well as vaccine application and production.

The Company,  with China CDC,  intends to apply for government  funding for this
project.


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

The SFDA  governs  the  regulation  of  vaccines  in  China.  Sinovac  takes the
following steps to gain approval from the SFDA to sell its vaccines in China:

Pre-Clinical Trials: The process involves in-vitro laboratory and in-vivo animal
- --------------------
testing.  It also includes a study on the technology  process,  and  establishes
quality  control and test  evaluation  standards for the safety,  efficacy,  and
stability of the vaccine throughout animal trial testing.

Clinical Trial  Approval:  After a formal review and evaluation of  per-clinical
- -------------------------
results, the SFDA makes a determination to approve or disapprove commencement of
human  clinical  trials using the product.  After three phases of human clinical
trial of a new drug,  the  independently  prepared  results  and  three  lots of
product  samples are submitted to the SFDA at the same time the Company  applies
for a new drug certificate and production license.





                                       22



New Drug  Certificate  & Production  License:  The new drug  certificate  grants
- ---------------------------------------------
approval for the research and development  process of a drug that has never been
approved for production or sale in China. The production license is approval for
vaccine production.  After completing three phases of clinical trial and passing
the  evaluation  by a  professional  delegation,  the SFDA will issue a new drug
certificated to the  manufacturer.  This grants the filing Company  intellectual
property  rights to this drug.  Chinese  administrative  protection  for the new
proprietary  drug  starts  from  the  date  of  the  issuance  of the  new  drug
certificate.

GMP   certificate:   The  GMP   certificate   is  for  the  monitoring  of  drug
- ------------------
manufacturers.  After receiving a new drug  certificate and production  license,
the  company  submits  an  application  for GMP  (Good  Manufacturing  Protocol)
certification.  This  provides  approval  for the  equipment  and control of the
manufacturing workshop of the particular drug.


A new drug is only officially approved for sale in the Chinese market once these
steps have been completed.  The  Company  believes  that  the  most  significant
milestone is the new drug certificate.



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


Disease  prevention is a lengthy  process.  The Company will strive to integrate
its  research  and  development,  and  marketing strategies, to supply  more new
products to eliminate human diseases.


The  Company,   with  the  cooperation  of  local  and   internationally   known
universities,  colleges  and  institutes,  and in  consideration  of the need of
disease control in China,  researches 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
an 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
providing a significant amount 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.

In the last three years,  Company  expenditures on research and development were
as follows:


2004 - Gross  expenditures  of  $1,005,000, less government grants recognized of
$719,000 for net expenditures of $286,000.  The  Company  received $1,688,000 in
government research grants in 2004, but the Company  did not meet the conditions
necessary for recognition of the full amount.

2003 - Gross  expenditures  of  $927,000  less  government  grants  received  of
$664,000 for net expenditures of $263,000.









                                       23



2002 - Expenditures of $25,000, with no government grants received.

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

All of the  Company's  facilities  conform  to the World  Health  Organization's
("WHO")  recommended  bio-safety  standards and Sinovac's primary  manufacturing
plant has been certified as meeting the GMP standard of the China SFDA.To comply
with GMP  operational  requirements,  the Company has written and  implemented a
quality  assurance  validation plan,  procedures,  and a complete  documentation
system.  The manufacturing  facilities for Hepatitis  vaccines,  Healive(TM) and
Bilive(TM),  have both received the Certificate of Good Manufacturing  Practices
for Pharmaceutical Products (n. 2515 and 2514) issued by the China SFDA. Company
facilities also meet GMP  requirements of Chinese and  international  regulatory
agencies.

Sinovac  maintains strict control  management of its staff,  plant  environment,
support  facilities,   raw  materials,   hygiene,   validation,   documentation,
manufacturing  process,  quality control,  product selling,  and sales follow-up
resolution.  The  Company's  personnel  are  trained  on  these  procedures  and
documentations  routinely to ensure a proficient comprehensive quality assurance
system and the quality of the finished products.

Sinovac bases its operations on an "excellence in service" concept. To meet high
goals,  the  Company  established  a  team  of  well-known  nationwide  experts,
professors  and doctors to provide  vaccine  customers  with support.  This team
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.

Sinovac's  facilities  are fully  compliant  with  world  advanced  GMP  Quality
Assurance   System   (QAS),   international   standards  on   bio-pharmaceutical
manufacturing.  The production  plant for Healive(TM)  vaccine was designed 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 North
America,  and the  installation and debugging  processes  completed on a turnkey
basis by a European  pharmaceutical  engineering  company. Our key equipment has
passed  the  validation  conducted  by  SVS,  which  is  an  FDA-designated  GMP
validation consulting company.

Tangshan Yian Biological  Engineering  Co., Ltd.  ("Tangshan  Yian") is a wholly
owned subsidiary of Sinovac.  Tangshan Yian is a research and development center
providing  support to the  parent  Company in  Beijing.  Tangshan  Yian owns and
operates  a  Biosafety  level III  Laboratory  (BSL-3)  that is  located  in the
Tangshan Yian facility.  The studies of deadly infectious viruses,  such as SARS
are  required  to be  conducted  in BSL-3 rated  laboratories.  The BSL-3 Lab in
Tanghsan Tian is constructed and managed according to WHO biosafety manual.

The Market
- ----------

     Global Market for Vaccines
     --------------------------

The global  vaccine market in 2001 was valued at $5.4 billion and is forecast to
reach $7.5 billion by 2005 (Datamonitor).  This predicted year-on-year growth of
8 to 10% makes vaccines the fastest growing  pharmaceutical  sector,  surpassing
even  prescription  drugs.  A key  driver of this  growth  is the  threat of the
emergence of new, more powerful super viruses such as SARS and avian influenza.

The efficacy of vaccines in preventing  viral  infections is  accentuated by the
prevalence of prevention programs  worldwide;  some 116 countries have initiated
childhood vaccination regimes.  World health authorities concur that vaccination
is the most cost effective way to deal with viral threats.

Quality  and cost  concerns  have  created a shortage of  effective,  affordable
vaccines  to prevent  hepatitis  A,  hepatitis  B, and  influenza.  No  approved
vaccines exist yet for SARS or avian influenza.

     Chinese Market for Vaccines
     ---------------------------

There is a  critical  and  growing  need in China  for safe,  highly  effective,
low-cost  vaccines  to protect the general  public and  particularly  those most
vulnerable  to  infectious  diseases  caused by viruses.  Between 1992 and 2002,
demand for vaccines rose 21.8% per year and  consistently  exceeded  vaccination
output  despite  large  gains in  production.  There  are many  causes  for this
phenomenon.

China's  population  is the  world's  largest  at 1.3  billion.  One of the most
challenging health concerns is the vaccination against diseases for its newborns
and elderly citizens. With persistent widespread outbreaks of hepatitis A and B,
the annual  shortage of influenza  vaccines in China is forecasted at some 15 to
20 million doses.

According  to China's  Vice-Minister  of Health,  19 million  babies are born in
China every year,  placing a large demand for vaccines  supplies.  However,  the
elderly growth is even larger and their need for vaccines just as vital. In 2001
China had 88 million  people age 65 or older.  This number reached 94 million in
2004 and by 2025  this age  group is  expected  to exceed  200  million  people.
According to the China  Elderly  Association,  senior  citizens will account for
11.8 percent of the total population in 2020, up from 7 percent today.

Hepatitis A is endemic in China with 2.4 million cases of acute  hepatitis every
year. Up to 80% of the  population  have been  infected  with  hepatitis at some
point in their lives.  According to the Ministry of Public Health, China reports
about half a million new cases of hepatitis B and 280,000  deaths from hepatitis
B-related  liver diseases each year.  More than 350 million will suffer lifelong
infection.

There are  several  factors  driving  China  toward  developing  and  dispensing
vaccines to combat viral diseases. They include support for its growing economy,
a growing middle-class population, increased awareness of health management, the
launch  of a  $145  million  nationwide  disease  prevention  program,  and  the
government's priority in developing the country's pharmaceutical industry.







                                       25



Vaccines must be affordable however.  China is still a developing country,  with
limited government funds for an Expanded Program for Immunization (EPI) program.
The best growth  potential  will be to  companies  that can produce high quality
vaccines at affordable prices.

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.

     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.

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 introduced a new approach to international health funding - the Global Fund
for  Children's  vaccines  (GFCV).  This  fund  helps  74  low-income  countries
reinforce  their  national  vaccine  programs and introduce  hepatitis B, yellow
fever  and  hemophilia  influenza  type B (HIB)  vaccines  into  their  national
immunization programs.

Sinovac  is  planning  to  develop  vaccines  that  are on  the  nongovernmental
organizations and the WHO Expanded Program on Immunization  (EPI) order lists in
order to capture the low-price, but big-demand vaccine market.

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

Rising incomes have contributed to the increased demand for commercial vaccines.
Many of those in the higher  income  bracket  choose to pay for  higher  quality
vaccines.  Cost  conscious  physicians  in private  health  centers  supply this
growing market.


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

First,  Sinovac  intends to target  progressive  geographic  expansion  with its
family of vaccines that target historically  devastating viruses. The Company is
building  and training a sales  organization  for the Chinese  domestic  market.
Concurrently  with its domestic  marketing  plan, the Company is  establishing a
marketing and sales  presence in Southeast Asia and other  developing  countries
through local distributors.  These distributors have over 10 years experience in






                                       26



commercialization and registration of vaccines and other pharmaceuticals through
established governmental relationships and local sales networks.

The marketing  strategy  contains a contingency  plan that goes into effect once
the Company creates a blockbuster vaccine for defeating emerging viruses such as
SARS or the avian flu. The Company believes a "first to market"  advantage opens
doors to international markets. In such a scenario, Sinovac intends to enter the
international  market with a worldwide  network of professional  sales teams and
sales networks, a reliable  customer-credit  management system, and an efficient
logistics system.

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

Sinovac's domestic marketing is greatly enhanced by Chinese government  programs
for inactivated  hepatitis A vaccines,  an inactivated  SARS vaccine,  and a new
human influenza vaccine.  As China's premier domestic developer and manufacturer
of these vaccines, Sinovac has an overwhelming advantage over its competitors.

The Company plans to continue pursuing a strategy of first launching its vaccine
products in market segments in China that present the highest  concentrations of
people  with  higher  earnings  bases.  Subsequently,  it will  expand its sales
program into less affluent  urban areas and rural  provinces.  Accordingly,  the
Company plans to enter these regional 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/

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

Sinovac's  international  market focus is on countries with significant  vaccine
demand, but without the means to afford expensive Western products.  The Company
has  started  with   Southeast   Asian   countries   through  a  joint   venture
licensing/marketing  agreement  with a successful  South  Korean  pharmaceutical
company.  In early 2005,  the Company  adapted its method of target  penetration
from utilizing an intermediary  marketing company to a tailored direct approach.
As such, the Company terminated its contract with Innopath  International and is
seeking well-established local companies within each targeted country.

Also in 2004,  Sinovac entered a vaccine export agreement with MEHECO to develop
the  Brazilian  market.   However,   due  do  a  Brazilian   Government  vaccine
distribution policy change, the Company terminated its contract with MEHECO.







                                       27



The  Company  intends to  accelerate  international  market  growth by placing a
priority on sales agreements with companies that can take advantage of Sinovac's
premier research and development capabilities.

The Company has set a goal to sell its  products  (Healive(TM),  Bilive(TM)  and
Anflu(TM)) in the majority of developing Southeast Asian markets within the next
five years.

Seasonality of Sales
- --------------------

The Chinese  traditional  New Year is usually in January or  February  and, as a
result,  demand is low during that period.  Sales generally  increase rapidly at
the end of March and then slow again in May and June.

One of the main end user groups for Sinovac  vaccines  are  students.  Sales are
relatively  low in July  and  August  when  students  are on  break  for  summer
holidays.  Sales  increase  dramatically  in  September  when new  students  are
required  to  receive  vaccination  during  school  registration.  Most  schools
organize vaccination programs for their students.

Strong vaccine sales continue through October as Chinese companies usually start
planning  their  budgets  for the  coming  year.  The China  CDC,  which  places
government  orders for vaccines,  also follows this  schedule.  In December,  as
Chinese New Year  approaches,  the China CDC usually  purchases  an inventory of
vaccines for the coming year. As a result,  there are usually many larger orders
at the end of each calendar year.


Other Developments
- ------------------

     International  Workshop  on  Development  of SARS and New  Human  Influenza
     ---------------------------------------------------------------------------
Vaccines
- --------

In March 2004,  the  Ministry of Science and  Technology  of China and the World
Health   Organization   held  a  joint  workshop  in  Beijing,   China  entitled
"International  Workshop  on  Development  of  Vaccines  for SARS and New  Human
Influenza Vaccines." Over 60 experts (scientists, physicians and ethicists) from
China and around the world attended the workshop. The workshop included parallel
meetings  and visits to  several  institutions,  related  to various  aspects of
vaccine  programs  on  SARS,  Influenza,  HIV/AIDS,  Japanese  Encephalitis  and
Malaria.

Sinovac's President and CEO, Dr. Yin was China's  representative for inactivated
SARS and human  influenza  vaccine  development  programs.  Dr. Yin and  Sinovac
deputy general manager, Mr. Jiansan Zhang,  presented the Company's research and
development  and reported on the  protocol of the phase I clinical  trial on the
inactivated SARS vaccine. Workshop participants reviewed data from animal trials
and  discussed   additional  measures  towards  refining  methodology  and  data
requirements prior to initiating Phase I trial in humans.

Immediately following the summit, Dr. Yin hosted a 12-member delegation from WHO
to tour the Company's facilities. Sinovac was the delegation's first stop during
its tour of Beijing and Shanghai corporations.








                                       28



     Former Malaysian Prime Minister Visited Sinovac
     -----------------------------------------------

On April 21, 2004,  former  Malaysian  Prime  Minister  Datuk Seri  Mahathir Bin
Mohamad  visited Sinovac with officials from the Chinese  People's  Institute of
Foreign  Affairs.  President and CEO, Dr. Weidong Yin gave a brief  introduction
about the inactivated hepatitis A and SARS vaccine projects to the visitors. The
former prime minister  expressed keen interest in the  inactivated  SARS vaccine
project by asking many questions about its research and development.  This visit
supports  Sinovac's  growing network with world leaders and  establishment of an
international presence in the biotechnology sector.


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

With the advent of a market  economy in China,  the  regulatory  system  began a
modernization   program  that  will   continue  for  the  next  several   years.
Concurrently,   the   pharmaceuticals   and   healthcare   industry   are   also
restructuring.   These  dynamic   conditions   present   tremendous   investment
opportunities  for  well-positioned  visionary  Chinese  companies,  as  well as
multinational companies.

Sinovac is emerging as a leader in this new era, but operates in an increasingly
competitive  environment.  China's  biotech  industry  consists  of roughly  600
companies  (not  including  extremely  small  companies),  of which 200  produce
pharmaceuticals, 200 produce amino acids, and the rest are in traditional fields
like brewery, food and chemicals.  Historically,  imported medicines make up 40%
of the Chinese  pharmaceutical  market,  while domestic producers (most of which
are state owned) have 60% of the market.

Most Chinese  citizens have to pay for their own vaccines,  even with the advent
of private medical and healthcare  insurance  programs in China. These insurance
programs do not cover  payment for  vaccines;  requiring the patient to purchase
the  vaccines.  Sinovac  believes  this health  conscious,  yet  price-sensitive
consumer  market favors the  Company's  products over cheaper less safe domestic
vaccines and more expensive Western competitors.

Simply stated,  the Company's  competition in China is between old,  inefficient
Chinese   companies  on  one  hand,   and  expensive,   huge,   state-of-the-art
international companies on the other. Sinovac believes it has strategic leverage
against  these  competitors  by  utilizing  its innate  advantages  as a Chinese
company  with  strong  connections  to  government  agencies  and  incorporating
state-of-the-art technologies and business practices. Sinovac's unique strategic
advantages are its investment in world-class  R&D facilities;  it's  experienced
visionary leadership; and its growing sales force.

There are many companies producing vaccines that compete with Sinovac's products
and we have the Company has identified the following companies in particular:

Hepatitis A vaccine:
- --------------------

Live Attenuated - Zhejiang PuKang, Changchun Changsheng,  Changchun Institute of
Biological Products, Kunming Institute of Biological Products







                                       29



Inactivated Domestic - Kunming Institute of Biological Products

Inactivated International - GlaxoSmithKline Inc., Merk

Hepatitis A and B vaccine:
- --------------------------

Domestic - no competitors identified

International - GlaxoSmithKline Inc.

Influenza vaccine:
- ------------------

Domestic  - Zhejiang  Tianyuan,  Changchun  Changsheng,  Shanghai  Institute  of
Biological  Products,  Changchun  Institute of  Biological  Products,  Changzhou
Yanshen

International - GlaxoSmithKline Inc., Pasteur, Chiron

     Chinese Competition
     -------------------

Most  Chinese  pharmaceutical  companies  use  outdated  production  facilities,
producing  raw products  with  low-tech  added value.  Some old and  state-owned
manufactures  do not  have  enough  capital  for  developing  new  products  and
improving the facilities.  Only a small fraction of annual sales,  about 2%, are
re-invested  into R&D of new  drugs.  Consequently,  the  majority  of  products
available in China are less safe and immunogenetic than western products.

An example of this are cheap live  attenuated  hepatitis A vaccines that compete
with  Sinovac's  Healive(TM).  These cheap vaccines are so unstable they require
strict storage and delivery conditions, and still expire in six months. When the
ambient  temperature is above 8 degrees Celsius (46.4 degrees  Fahrenheit),  the
hepatitis A vaccine may lose its efficacy,  and becomes unsuitable for use. This
makes delivery to many undeveloped areas impracticable.

Sinovac  enjoys a  number  of  advantages  over its  domestic  competitors.  For
example,  it is not  required,  as are most Chinese  vaccine  manufacturers,  to
allocate up to 70% of their vaccine  production  capacity for federal government
immunology  programs.  The profit  margins for these  programs are usually quite
low.  Another,   more  significant   example,  is  the  difficulty  of  domestic
competitors access to major financing for expansion purposes. This is one of the
greatest limitations Chinese vaccine manufacturers deal with,  particularly when
these companies are marketing inferior biotechnologies.

The venture  capital market in China is still in its infancy and accessing funds
is problematic.  This forces Chinese vaccine  manufacturers  to look for funding
from  outside  China.  Sinovac  however  has  already  made steps in  overcoming
growth-funding  challenges.  A vital step occurred  when Sinovac  entered into a
Financial  Advisory  Agreement  with  Credit  Suisse  Advisory  Partners  AG,  a
100%-owned   subsidiary  of  Credit  Suisse  Group   headquartered   in  Zurich,
Switzerland,  whereby Credit Suisse Advisory  Partners will act as the Company's
exclusive  financial advisor.  Credit Suisse Group is a leading global financial
services company.







                                       30


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

International   competitors  include  large  international   pharmaceutical  and
biotechnology  companies with great resources.  This  competition  tends to come
from  well-established  biopharmaceuticals  with deep pockets and a proven track
record  for  successful  product  development  and  commercialization.  However,
according to  international  research,  these  mega-biopharmaceutical  companies
invest  relatively  little in R&D and  manufacturing  capacity for vaccines that
would benefit  developing  countries for five related reasons:  competition with
more profitable vaccine ventures; the perception that demand for new products is
low; costs of production are relatively  high;  market pressures are intense and
rapidly changing;  and products for the industrialized  world are diverging from
those for poorer countries.


C.   Organizational Structure
     ------------------------


Sinovac now owns 71.56% of Sinovac Biotech Co., Ltd., (Sinovac  Beijing) (51% at
December 31, 2004) a company  organized under the laws of the People's  Republic
of China.  The Company also owns 100% of Tangshan  Yian  Biological  Engineering
Co., Ltd., a company also organized  under the laws of the People's  Republic of
China.  Therefore,  the Company has two  subsidiaries - one that is wholly owned
and one that is majority owned.


Acquisition of Additional 20.56% of Sinovac Beijing
- ---------------------------------------------------

On November 30, 2004,  Sinovac,  entered into a share  purchase  agreement  (the
"Share  Purchase   Agreement")   with  China  Bioway  Biotech  Group  Co.,  Ltd.
("Bioway"),  Beijing Keding Co., Ltd. ("Keding") and Shenzhen Bio-Port Co., Ltd.
("Shenzhen")  to  purchase  an  aggregate  20.56% of Sinovac  Beijing,  its main
operating subsidiary.


In accordance  with the Share Purchase  Agreement,  Sinovac paid $3,310,000 cash
for the  additional  20.56% of  Sinovac  Beijing,  to the  following  companies:
acquired  9.73% from  Bioway  US$1,570,000;  acquired  7.92% from  Shenzhen  for
US$1,270,000;  and acquired 2.91% from Keding for  US$470,000.  The  transaction
closed on February 4, 2005.



D.   Property, Plants and Equipment
     ------------------------------

Office Space
- ------------

Sinovac's corporate headquarters and primary research and development facilities
are located in the Beijing University Biological Industry Park in a 4,113 square
meter, state-of-the-art facility, of which more than 1,000 square meters is used
as an  office  building  and  more  than  2,000  square  meters  is used for the
production plant for hepatitis A vaccine.


Plants
- ------

The  Company's  new influenza  vaccine  production  line is situated next to its
existing Beijing headquarters,  at a new manufacturing facility now being built.






                                       31



This 2,600 square meter facility,  built to Chinese Good Manufacturing  Practice
(the "GMP")  standards,  is expected to have a production  capacity of 2 million
doses of flu vaccine per year.

The Company's  Tangshan Yian facility conducts research and pilot production for
other,  in-development  vaccines.  This  facility is 4,300  square  meters,  and
includes a world class Biosafety level III Laboratory ("BSL-3"),  Cell Culturing
Workshop,  Pilot Trial Production Workshop,  Reagents Manufacture Workshop,  and
Research Lab for R&D of the split flu vaccine (AnfluTM). The facility is located
in the New Hi-tech  Development  Zone of Tangshan City,  160 kilometers  east of
Beijing.  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 low-cost  research and  development  and
manufacturing.  The advantages of Tangshan  Yian's  state-of-the-art  facilities
expanded  manufacturing  capabilities  should enhance the competitive ability of
the Company regarding research and production.

Equipment
- ---------

Steel  furring  is used  for the main  portion  of the  Company's  manufacturing
facility,  and the  architecture  is  concise.  The  manufacturing  facility  is
designed  based on  Chinese  GMP  requirements  and is  divided  into  clean and
non-clean zones. Sinovac's manufacturing facility grade classifications include:
grades A and B  correspond  with  class  100,  M3.5,  ISO 5;  grade C with class

facilities  are selected for the  establishment  of the Company's  manufacturing
facility.  The Company's subsidiary  facilities are mainly constructed in China.
Temperature  control is designed to be automatic.  The  production  control is a
centralized  design.  The Company's  manufacturing  facility includes  necessary
features such as dressing rooms and air brakes.  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
     -----------


Management  has  determined  that, in  2003  and  2002, the  Company should have
treated the acquisition of certain licenses as purchases of  in-process research
and  development.  Management  has  also determined  that in  2003, the  Company
incorrectly  capitalized certain research and development costs that should have
been expensed.  Management  has  further  determined  that, in 2001, the Company
should have commenced amortization of its hepatitis  A vaccine  license  at  the
date of purchase, when previously amortization did not  begin  until July  2002.
Accordingly, the Company  has  restated its  financial  statements  for the year
ended  December 31, 2004.  The following  discussion  relates  to  the  restated
amounts.


The Company has made certain  accounting  estimates that have a material bearing
on the financial statements. The principal such estimates are:








                                       32



Stock-based compensation
- ------------------------

Stock-based compensation is a very  significant  expense for the Company, but is
based  on  estimates that  have a  subjective  element.  The Company employs the
Black-Scholes  option  pricing  model  which  in turn is  based  on (among other
things) assumptions regarding rates of return  and stock volatility. To estimate
the  risk-free  rate of  return, the Company uses  the US Treasury bill rate for
instruments with a similar term to the life  of the option being granted.  Since
the  Company  has a relatively  short trading  history,  it has  looked  at  the
volatility of the stock  of other  publicly traded companies and used these as a
guide.

The Company  has  estimated the  expected volatility of  its stock at 74%.   The
following table shows the effect of a change in the expected volatility of 10%:

Given  the nature of the estimated volatility of a stock, it is not practical to
provide  a  meaningful  assessment  of  historical  accuracy  of  the  estimated
volatility used.  It is very likely that the  expected volatility will change in
future periods and the changes could be material.

Amortization of Intangible Assets
- ---------------------------------

The Company has amortized  the value of  intangible assets, being  licenses  and
permits,  over  an  estimated  10-year  useful  life.   The  estimated  life  of
intangible assets is inevitably  subjective, however at least once per year, the
Company  reevaluates the market  opportunities  for its  products and determines
whether the remaining useful life estimate is still reasonable.

The following table shows the effect of a change in the estimated useful life of
licenses and permits of 10%:









                                       33

Loss per share          $     (0.14)    $      (0.14)   $      (0.14)


Given  the nature  of estimating  the useful life of long-term assets, it is not
yet possible to provide a  meaningful assessment of  historical  accuracy of the
useful life estimates employed. It is very  likely  that the  useful life of the
licenses  and  permits will  be different  from the estimate employed,  and  the
changes could be material.  Changes in  the  estimated life of the  licenses and
permits  will not  have a bearing  on  the  total  amount charged to  operations
over the life of the  assets, but  could change  the  results of  operations and
financial position in any given period.

Allocation of Intangible Assets
- -------------------------------

When the Company acquired its interest  in Sinovac China, it had to allocate the
excess  of  its purchase price over  net tangible  assets to  various classes of
intangible  assets.  The Company based its estimates on the projected cash flows
to be earned from each product.

Given the nature of estimating the relative value of long-term assets, it is not
possible  to  provide  a meaningful  assessment  of  historical  accuracy of the
valuation  allocation  estimates  employed.  It is  very likely  that the actual
values of the  licenses  and  permits  will  be  different  from  the  estimates
employed and the changes could be material.  Changes  in the  relative value  of
each of the licenses and permits will  not have a  bearing on  the total  amount
charged to operations over the life of the assets, but  could change the results
of operations and financial position in any given period.

The following table summarizes the  amortization  expense for  each component of
licenses and  permits, allowing the  reader to  draw  inferences  regarding  the
sensitivity of earnings to different allocation models.

Income Tax Valuation Allowance
- ------------------------------

The  Company has  recorded  a $860,300  deferred  income  tax asset based on the
difference in timing  of  certain  deductions  for  income  tax  and  accounting
purposes. The ability of the Company to  ultimately  derive  a  benefit from the
deferred tax asset depends on the existence of sufficient taxable  income of the
appropriate character  within the  carryforward  period available  under the tax
law. The Company has reviewed available information, both positive and negative,
and has concluded that realization is probable.  If the Company's  evaluation of
the circumstances is not correct, the  Company  will have to record a  charge to
operations in respect of any over-accrual of the benefit.


Year ended December 31, 2004 compared with the year ended December 31, 2003

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

In the following  discussion of the  Company's  operating  results and financial
condition,  all  financial  amounts  have been  rounded to the nearest  thousand
dollars.

          Sales
          -----


Sinovac's  sales  reflect  the  value of  vaccines  sold  less any  returns  and
discounts.   Company  sales  in  2004  and  2003  were  entirely   comprised  of
Healive(TM). The Company generated revenue of $6,454,000 and $2,839,000 in sales
of  Healive(TM)  for the years ended  December  31, 2004 and  December 31, 2003,
respectively.  Revenue  growth in 2004 was due to an expanded  sales network and
improved corporate  profile.  The number of doses sold increased from 433,000 in
2003 to 1,002,106 in 2004.


          Gross Profit
          ------------


The Company's gross profit reflects  the  contribution from  sales after  direct
costs, such as production  labor and production  facilities costs.  Gross profit
margin was 70.0% and 61.8% for  the years ended  December 31, 2004  and December
31, 2003, respectively. These gross profit amounts are exclusive of depreciation
and amortization amounts of $202,000  for 2004 and  $202,000 for 2003.  If these
depreciation and amortization amounts  had been included in the determination of
gross profit,  the gross profit  margin would have been 66.8% and  54.6% for the
years ended December 31, 2004 and December 31, 2003, respectively.  The increase
in gross profit margin was  due to economies of scale;  increased  production of
Healive(TM) decreased the average cost per unit.

         Government Research Grant
         -------------------------

The Chinese  government  provided grants  to  the Company which are brought into
income in the period in which the research and development expenses are recorded
and the conditions opposed by the government authorities  are fulfilled.  In the
year ended December 31, 2004, the Company received a Chinese government SARS and
Avian flu research grants of $1,640,000  and $48,000, respectively.  In the year
ended December 31, 2004, the Company recognized government research grant income
of $719,000, compared to $664,000 in the previous year.










                                       35



          Selling, General and Administrative Expenses
          --------------------------------------------

Selling,   general  and   administrative   expenses  ("SG&A  expenses")  include
non-production  related wages and salaries,  consulting fees,  freight,  travel,
occupancy,  advertising,  public  company  costs  and  professional  fees.  SG&A
expenses were  $4,415,000  and  $1,629,000 for the years ended December 31, 2004
and December 31, 2003,  respectively.  Company sales expenses  increased in 2004
due to  exploration  of new markets and efforts to improve  sales  networks  and
sales strategy.  Administrative  expenses of $140,966  relating to Tangshan Yian
were  included in the  consolidated  financial  statements  as the result of the
acquisition of that company. Sinovac expects to see additional increases in SG&A
to support continuing market penetration and brand awareness.

          Stock-Based Compensation
          ------------------------


The Company incurred stock-based compensation of $4,428,000 and $120,000 for the
years ended  December  31, 2004 and  December  31,  2003,  respectively.  In the
current  fiscal year,  2 million  stock  options were granted to the  directors,
employees and  consultants  at an exercise  price of $4.55 per share.  The stock
options granted in 2004 have an estimated fair value of $2.85 per share and have
different  vesting  schedules  and, as  a result, the  Company  has unrecognized
compensation  costs of about $3.4  million.  This  unearned  component  will  be
recognized over the remaining vesting period. This item does not reduce the cash
balance of the Company but reflects the fair value of the above-mentioned  stock
options.


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


Research  and  development  expenses  reflect amounts spent on the split flu and
SARS  vaccines.  Research  and  development  expenses  totaling  $1,005,000  and
$927,000  for  the  years  ended  December  31,  2004  and  December  31,  2003,
respectively, represent activities on the split flu (AnfluTM) vaccine.


The Company  commenced  the study and research of a SARS vaccine  after the SARS
outbreak  of 2003.  In 2004,  Sinovac  became  the  first  company  in the world
approved to commence a human clinical trial of a SARS vaccine.  On May 22, 2004,
the  commencement  of the phase I clinical  trial was  announced  when the first
clinical trial volunteer received his first  inoculation.  A research grant from
the Ministry of Science and Technology and other central government  agencies on
behalf of the Chinese government as a whole, has provided sufficient funding for
the phase I clinical trial and  demonstrates  the support for the Company's SARS
vaccine research.

          Provision for Income Taxes
          --------------------------


The Company  generated an income tax recovery of $767,000 in 2004.  It accrued a
$93,000  liability for income taxes on profits in Sinovac Beijing and recorded a
$860,000  deferred tax recovery that offset this expense.  The Company's taxable
income in China is subject to Chinese  income tax  regulations  for its reported
statutory  income  declaration  at a tax rate in  accordance  with the  relevant
income tax laws and  regulations  applicable  to  Sino-foreign  joint  ventures.
Sinovac Beijing is subject to a 7.5% corporation  income tax rate until 2006 and
15% tax rate after that.  Tangshan  Yian is eligible for a full  exemption  from








                                       36



income  taxes for two years and a 50%  reduction  in income  taxes for the three
years following its first profit-making year.  Currently,  Tangshan Yian is in a
loss position.


          Interest and Financing Expenses
          -------------------------------

Interest and  financing  expenses were $369,000 and $269,000 for the years ended
December  31,  2004 and  December  31,  2003,  respectively.  The 2004  increase
reflected higher levels of debt, largely due to the purchase of Tangshan Yian.

          Net Loss
          --------


The Company's net loss was  $4,667,000 and $872,000 for the years ended December
31, 2004 and December 31,  2003,  respectively.  The increase in net loss in the
current year over the previous period was primarily due to increased stock-based
compensation  since the  increase  in SG&A was  largely  funded by an  increased
contribution from product sales.


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

Sinovac's  capital  requirements  have  generally  been funded by cash flow from
sales revenue and issuances of common stock.  Cash and cash equivalents  totaled
$2,605,000 at December 31, 2004,  which is not  sufficient to fund the Company's
business and expansion  plans over the next 12 months.  Sinovac's plans for 2005
include:

     o    Spending $4 million constructing an influenza vaccine production line;
     o    Acquiring an additional 20.56% of Sinovac Beijing,  giving the Company
          a 71.56%  interest in that company,  for cash  consideration  of $3.31
          million;
     o    Product promotion campaigns.

Sinovac  plans to raise  necessary  capital from the sale of equity  securities.
There can be no assurance that any that such financing will be available,  if at
all, on terms  acceptable to the Company.  If additional funds are raised by the
issuance of equity  securities,  stockholders  may experience  dilution of their
ownership interest.


The Company  generated net cash of $1,185,000 and $1,107,000 for the years ended
December 31, 2004 and December 31, 2003,  respectively.  Net loss for the period
of  $4,667,000  incorporated  certain  non-cash  charges  including  stock-based
compensation  ($4,428,000),  a  provision  for  doubtful  debts  ($374,000)  and
depreciation   ($784,000).   Changes  in  operating   working  capital  consumed
$1,626,000  of cash,  resulting in net cash used in  operations  of  $1,130,000.
Accounts receivable  increased as a result of increased sales. The proportionate
decrease in cash used, compared to earlier years, was primarily  attributable to
lower working capital requirements in the third year.

The  Company's  financing  activities  generated   $6,545,000,   which  included
$5,288,000 of newly raised share capital and $1,281,000 from government  funding
(net of qualified  research  and  development  expenditures).  In the year ended
December  31,  2004,  the Company  paid  $399,000 to reduce  amounts  owing to a
non-controlling  shareholder  of Sinovac  Beijing.  Other  financing  activities
included loan proceeds of $3,268,000, loan  payments  of $3,099,000 and proceeds
from shares subscribed of $207,000.








                                       37


In the year ended  December  31, 2004 the Company used  $4,227,000  in investing
activities,  which included $1,650,000 to acquire property,  plant and equipment
offset by cash of $42,000  acquired with the purchase of Tangshan  Yian.  During
the current period,  Sinovac negotiated agreements that govern the purchase of a
further  20.56%   interest  in  Sinovac   Beijing.   In  connection  with  these
negotiations,   the  Company   advanced   $2,227,000   to  two   non-controlling
shareholders  of Sinovac  Beijing as deposits  on account of the Share  Purchase
Agreement.  The deposits bear interest at 5.31%,  and the principal and interest
will be repaid to us the  Company  when we it makes  full  payment  of the share
purchase consideration.  The Share Purchase Agreement for the acquisition of the
additional 20.56% of Sinovac Beijing closed on January 31, 2005.


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

In 2005 the Company expects to increase  production and sales of HealiveTM,  and
initiate  production  and  sales  of two  new  products,  BiliveTM  (a  combined
inactivated  Hepatitis A and B vaccine) and AnfluTM (an  influenza flu vaccine).
Sales of both  products  are  expected  to  follow  HealiveTM's  sales  pattern,
beginning  slowly the first  year and  growing  dramatically  (100% or more) the
following years.

BiliveTM  will be the first new  product  to launch in 2005 and may take some of
HealiveTM's  market.  As a  result,  the  sales  growth  rate of  HealiveTM  may
stabilize.

Ideally,  AnfluTM  marketing  will  begin in late  summer  of 2005,  with  sales
beginning  in the fall.  This  market  timing  will  enable the  Company to take
advantage  of  their  HealiveTM  and  BiliveTM  promotions,  thereby  leveraging
Sinovac's growing name recognition and confidence in domestic market.

The  Company is not  certain  however  that the SFDA will  approve  the  vaccine
production  license  for  AnfluTM in time to produce  sufficient  quantities  of
vaccines  for sale in the 2005 - 2006 flu season.  If  approval is not  received
this year, the Company is assured it will happen in time to produce vaccines for
the flu season in 2006 - 2007.

Production costs for HealiveTM should continue to decrease,  however, first year
production costs for BiliveTM and AnfluTM will offset  HealiveTM's  lower costs.
Combining the above two driving factors, the Company expects the gross margin to
remain at the same level in 2005.

The last known uncertain factor that could have a material effect on the Company
is a change in government policy on vaccine distribution. If the regulatory body
changes China's vaccine  distribution  channel,  which is currently  through the
China CDC system, the Company will need to make changes in its general marketing
and sales strategy for the domestic market.









                                       38



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 $1,348,103 to $729,248.
This cash was used to purchase plant equipment, totalling  $348,190, and payment
for Licenses and permits, $381,058.

Cash  used in  operating activities was  substantially  unchanged, increasing by
$5,913 to  $1,058,854  in 2003, from  $1,052,941  in 2002.  While the  loss from
operations decreased, cash applied to working capital balances increased.


     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
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, a fourfold increase 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.   These cost of sales amounts are
exclusive of  depreciation  and amortization amounts  of $201,802 for  2003  and









                                       39


$201,648 for 2002.  If  these depreciation  and  amortization  amounts had  been
included in the determination of gross  profit,  the gross profit  margin  would
have been 54.6% and 45.1% for the years ended December 31, 2003 and December 31,
2002, respectively.

The  Company  recognized  $664,251  in  government  research  grants in 2003 for
research on a SARS vaccine.

Expenditures  on sales and general  administration were  $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  totalled $926,746 in 2003, compared to
$24,535 in 2002.  The increase in  spending  from  last year  primarily reflects
work on  the SARS  vaccine, although  other factors include split  flu  clinical
development activity  and work  to  obtain obtained  new drug  license  for  the
hepatitis A&B vaccine.

The  Company's  most important  research  and  development  achievement  is  the
inactivate SARS vaccine.   The SARS research  and development  expenditures  was
supported by a grant from the China government for $664,251 (RMB 5,500,000).


     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.

H.   Documents on Display
     --------------------

The above  contracts  respecting  the Company may be inspected at the  Company's
Canadian counsel's office in the Province of British Columbia,  located at Suite
2550,  555 West Hastings  Street,  Vancouver,  British  Columbia,  V6B 4N5 for a
period of 30 days following the filing of this Annual Report.


I.   Subsidiary Information
     ----------------------

The Company is a 71.56%  majority owner of Sinovac  Biotech Co., Ltd., a company
organized under the laws of the People's  Republic of China, and a 100% owner of
Tangshan Yian Biotechnology Engineering Co., Ltd., a company organized under the
laws  of the  People's  Republic  of  China.  Therefore,  the  Company  has  two
subsidiaries - one which is wholly owned and one which is majority owned.


ITEM 11 - QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
- -------------------------------------------------------------------

The carrying value of cash and cash equivalents, accounts receivable, short-term
loans payable, accounts payable and accrued  liabilities approximate  their fair
value because of the  short-term nature of these instruments.  The fair value of
long-term debt is based on the discounted value of contractual cash flows and as
at December  31, 2004,  approximates its  carrying value.  The discount  rate is
estimated using  the rates  currently offered  for debt with  similar  remaining
maturities.

While  the Company's  financial  statements  are  denominated  in  United States
dollars,  most of its  operations  are located in China,  where transactions are
denominated  in the  Chinese currency  RMB.  During  the year ended December 31,
2004,  the exchange  rate  between  the United  States  dollar  and the  RMB was
essentially fixed at US$1.00 = 8.28 RMB.

Subsequent to  December 31, 2004, the fixed exchange rate with the United States
dollar was  abandoned in favour of a link to a  basked of world currencies.  The
following table shows the relative  holdings of  monetary assets and liabilities
allocated between United States dollars and RMB, for those monetary assets which
are held in a combination of United States dollars and RMB. The table also shows
the relative effect on these balances of a 10% change in the exchange rate.






                                       65

                                                                         Rate
                                    ------     -----      -------     ---------
Cash and cash equivalents          775,167  15,151,436   2,605,051       7.0%
Due from related parties - net   1,671,048  10,860,363   2,982,686       4.4%
Accounts payable and accrued
liabilities                        192,573  19,263,656   2,519,102       9.2%

All  other  monetary  assets  and  liabilities  are  substantially  or  entirely
denominated  in RMB.  For these  assets  and liabilities,  a 10%  change  in the
exchange rate  would  result in  a  10%  change  in  the  United  States  dollar
equivalent.   We  believe  that  the selected  rate change  of 10% is reasonably
possible in the near term.

Sinovac has not entered into derivative contracts either to hedge existing risks
or for speculative purposes.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of
Sinovac Biotech Ltd.
(formerly Net-Force Systems Inc.)


The  consolidated  balance sheets  of Sinovac  Biotech Ltd.  (formerly Net-Force
Systems Inc., the "Company") as at December 31, 2004 and 2003,  and  the related
consolidated statements of stockholders' equity, operations and  cash  flows for
each of the years in the three year period ended December 31, 2004  were audited
by other auditors who have ceased operations and  whose  report  dated March 11,
2005 expressed an unqualified opinion on those statements before the restatement
adjustments described in Note 2.

As  discussed  above,  the  consolidated  balance  sheets  of the  Company as at
December  31,  2004  and  2003,  and  the  related  consolidated  statements  of
stockholders' equity, operations  and  cash flows  for each  of the years in the
three year period ended  December 31, 2004 were audited by  other  auditors  who
have ceased operations.  As described in Note 2, in 2005, the Company's Board of
Directors, upon recommendations  from the Securities  and  Exchange  Commission,
revised the accounting for purchased in-process research and  development  costs
and the commencement date for amortization of a drug  license.  As a  result  of
this revision, the net loss and the comprehensive loss for  the 2004 fiscal year
was decreased by $85,000, while the net loss and the  comprehensive loss for the
fiscal  years of  2003  and  2002  were  increased  by  $410,768  and  $573,844,
respectively.  Loss  per  share for  the 2004 fiscal year was decreased by $0.01
and increased by $0.01 for the 2003 fiscal year.  The loss per share information
for the  2002  fiscal year  was  unchanged.  The total assets as at December 31,
2004 and 2003 were decreased by $946,612 and $1,113,612, respectively. The total
accumulated deficit as at December 31, 2004 and 2003 was  increased by  $496,248
and $581,248, respectively.  Various components of investing  and operating cash
flows were also reclassified without any net impact  on cash flows.  We  audited
the adjustments described in Note 2 that were applied  to restate  the financial
statements of 2004, 2003 and 2002.  Our  procedures  included i)  assessing  the
appropriateness of the accounting  for  the purchased  in-process  research  and
development costs and the commencement date of amortization of the drug  license
and associated impacts on the related accounts, and ii) testing the mathematical
accuracy of the  adjustments  to license and permit, deferred income tax assets,
minority  interest,  accumulated  deficit,  purchased  in-process  research  and
development  costs,  amortization  of  license  and  permit  and  the  resulting
mathematical impact on net  loss, comprehensive loss, basic and diluted loss per
share, total assets and  shareholders'  deficit accounts. In our  opinion,  such
adjustments are appropriate and have been properly applied. However, we were not
engaged to audit, review,  or  apply  any  procedures to the 2004, 2003 and 2002
financial statements of the Company other than  with respect to such adjustments
and, accordingly, we do not express an opinion or any other form of assurance on
the  Company's  financial  position  as  at  December 31, 2004 and 2003, and the
results of its operations and cash flows for each of the years in the three year
period ended December 31, 2004 taken as a whole.

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, 2004 and
2003,  and  the  related  consolidated   statements  of  stockholders'   equity,
operations  and cash  flows  for each of the  three  years in the  period  ended
December 31, 2004.  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,
2004,  and 2003 and the results of its operations and its cash flows for each of
the three  years in the  period  ended  December  31,  2004 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, 2004 and 2003
(Expressed in U.S. Dollars)
Restated - Note 2
- --------------------------------------------------------------------------------


1.   Nature of Business and Basis of Presentation
     --------------------------------------------

     These consolidated  financial statements are those of Sinovac Biotech Ltd.,
     formerly  Net-Force  Systems  Inc.,  ("parent  company"),   its  51%  owned
     subsidiary  Sinovac Biotech Co., Ltd.  ("Sinovac China") and its 100% owned
     subsidiary  Tangshan Yian  Bioengineering  Co., Ltd.  ("Tangshan Yian") and
     Sinovac Biotech (Canada) Ltd. ("Sinovac  Canada").  Collectively,  they are
     referred to as "the Company".

     The Company,  through its  subsidiaries,  Sinovac China and Tangshan  Yian,
     primarily  operates  in China and it is in the  business  of  research  and
     development, production and sales of pharmaceutical products. Sinovac China
     was  incorporated  under the laws of China on April 28,  2001.  In  January
     2004,  the Company  acquired a 100% interest in Tangshan Yian (see note 7).
     Tangshan Yian was incorporated under the laws of China on February 9, 1993.

     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.   Outside  the
     Agreement, a member of Sinovac management purchased 6,544,830 shares of the
     17,091,032  Net-Force  shares   of  common  stock  outstanding  before  the
     acquisition,  resulting  in shareholders and  management  of Sinovac having
     control of the combined entity. 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.

     The Company  incorporated a 100% owned  subsidiary  called Sinovac  Biotech
     (Canada) Ltd.,  under the Canadian  Business  Corporations  Act, on May 12,
     2004. Sinovac Canada had no operations in 2004.

2.   Restatements
     ------------

     Management has determined that, in 2003 and 2002, the  Company  should have
     treated the acquisition  of  certain  licenses as  purchases of  in-process
     research and development. Management has  also determined that in 2003, the
     Company capitalized certain research and development costs that should have
     been expensed. Management has further determined that, in 2001, the Company
     should have commenced amortization of its hepatitis  A  vaccine  license at
     the date of purchase, in April 2001, instead of in July 2002.  The  Company
     has restated its financial statements as at  December 31, 2004 and 2003 and
     for  the  years  ended  December 31, 2004, 2003 and 2002  to  correct these
     errors.

     The effect of  these  adjustments on the  Company's  consolidated financial
     condition is as follows:

Notes to Consolidated Financial Statements

(Expressed in U.S. Dollars)
Restated - Note 2
- --------------------------------------------------------------------------------


3.   Significant Accounting Policies
     -------------------------------

     (a)  Basis of Presentation

          These  consolidated  financial  statements include the accounts of the
          parent company,  its 51% owned subsidiary,  Sinovac China and its 100%
          owned subsidiaries,  Tangshan Yian and Sinovac Canada. 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.

     (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)  Restricted Cash

          Restricted  cash is cash  held as  collateral  for  letters  of credit
          issued and is  classified  based on the  expected  expiration  of such
          facilities.

     (e)  Inventories

          Inventories  are stated at the lower of cost or replacement  cost with
          respect to raw  materials and lower of cost and net  realizable  value
          with  respect  to  finished  goods.  Cost  generally  determined  on a
          first-in,  first-out basis and includes direct material, direct labour
          and overheads. Net realizable value represents the anticipated selling
          price less estimated costs of completion and distribution.

     (f)  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
            Machinery and equipment                          8 - 10 years
            Motor vehicles                                   5 years
            Office equipment and furniture                   5 years
            Plant and building                               30 years

     (g)  Licenses and Permits

          The Company capitalizes  the purchase  cost of vaccines if the vaccine
          has received a new drug  certificate  from  the  Chinese Food and Drug
          Administration ("SFDA"). If the vaccine has not  received  a  new drug
          certificate, the purchase cost is expensed as in-process  research and
          development.

          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 10 years.  Carrying  values of such
          assets are reviewed at least  annually and whenever  events or changes
          in  circumstances   indicate  that  the  carrying  value  may  not  be
          recoverable  from 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  adjustments  to the carrying  value of the licenses and
          permits for the years ended 2004, 2003 and 2002.

     (h)  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 have
          been no impairment losses recognized to date.

     (i)  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.

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

     (j)  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.

          Shipping and handling  fees billed to customers are included in sales.
          Costs  related to shipping and  handling are part of selling,  general
          and administrative expenses in the consolidated statements operations.
          EITF No.  00-10,  Accounting  for Shipping and Handling Fees and Costs
          allows for the presentation of shipping and handling  expenses in line
          items other than cost of sales.  In 2004,  $39,633 (2003 - $16,347 and
          2002 - $7,573)  related to shipping and handling costs was included in
          selling,  general  and  administrative  expenses  in the  accompanying
          consolidated statements of operations.

     (k)  Advertising Expenses

          Advertising  costs are  expensed as incurred  and  included in selling
          expenses.  Advertising  costs were $71,399  (2003 - $14,875 and 2002 -
          $77,790) for the year ended December 31, 2004.

     (l)  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.

          Government research grants to reimburse expenses issued are taken into
          income in the  period  in which  the development expenses are recorded
          and  the   conditions  imposed   by  the  government  authorities  are
          fulfilled.

     (m)  Foreign Currency Transactions

          The parent  company and its  subsidiaries  maintain  their  accounting
          records in their functional currencies, i.e. U.S. dollars and Renminbi
          Yuan ("RMB")  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.

          The assets and liabilities of the foreign subsidiaries,  Sinovac China
          and Tangshan Yian, 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  has  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".  The Company has a stock  option plan that is described
          more fully in note 12.

     (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  discloses this  information on its Statement of Stockholders'
          Equity.  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".  1,500,000  shares held in escrow
          and  contingently  cancelable are excluded in the  computation of loss
          per share until the conditions  for their release are satisfied  (note
          7).  Diluted  loss per share is equal to the basic  loss per share for
          the  periods  presented  because  common  stock  equivalents  that are
          outstanding  are  anti-dilutive.  However,  they  may be  dilutive  in
          future.

     (q)  Financial Instruments and Concentration of Credit Risks

          The fair values of financial  instruments  are estimated 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,
          short-term loans payable,  accounts  payable and accrued  liabilities,
          and due from and to related parties  approximate their fair value. The
          fair  value of  long-term  debt is based  on the  discounted  value of
          contractual  cash flows and at December  31,  2004,  approximates  its
          carrying  value.  The  discount  rate is  estimated  using  the  rates
          currently offered for debt with similar remaining maturities.

          The  Company  operates  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
          government  agencies.   One   customer   accounted   for   21%   (2003
          - 16%)   of   total   sales  for  year  ended  December 31, 2004.  Two
          customers accounted for 41% of total sales for the year ended December
          31,  2002.  Concentration  of  credit  risks  with  respect  to  trade
          receivables  is  limited  since  the  Company  has a large  number  of
          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 risk.

     (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  adoption  of this
          pronouncement  does not have an impact on its  consolidated  financial
          statements.

     (s)  New Accounting Pronouncements

          In November 2004, the FASB issued SFAS No. 151,  "Inventory  Costs--an
          amendment of ARB No. 43, Chapter 4", which is the result of the FASB's
          project  to  reduce   differences   between  U.S.  and   international
          accounting  standards.  SFAS No. 151  requires  idle  facility  costs,
          abnormal  freight,  handling  costs,  and amounts of wasted  materials
          (spoilage) be treated as current-period  costs. Under this concept, if
          the costs  associated  with the actual level of spoilage or production
          defects are greater than the costs associated with the range of normal
          spoilage or defects, the difference would be charged to current-period
          expense,  not  included  in  inventory  costs.  SFAS  No.  151 will be
          effective for inventory  costs incurred  during fiscal years beginning
          after June 15,  2005.  The  adoption  of SFAS No. 151 does not have an
          impact on the Company's consolidated financial statements.

          In December  2004, the FASB issued SFAS No.  123(R),  "Accounting  for
          Stock-Based  Compensation".  SFAS 123(R) establishes standards for the
          accounting for  transactions  in which an entity  exchanges its equity
          instruments for goods or services. This Statement focuses primarily on
          accounting  for  transactions  in which  an  entity  obtains  employee
          services in share-based  payment  transactions.  SFAS 123(R)  requires
          that the fair  value  of such  equity  instruments  be  recognized  as
          expense  in  the  historical  financial  statements  as  services  are
          performed. Prior to SFAS 123(R), only certain pro-forma disclosures of
          fair value were  required.  SFAS  123(R)  shall be  effective  for the
          Company as of the beginning of the first  interim or annual  reporting
          period that begins after  December 15, 2005.  The adoption of this new
          accounting  pronouncement  does not have an  impact  on the  Company's
          consolidated financial statements.

          In  December  2004,  FASB  issued  Statement  No.  153,  "Exchange  of
          Nonmonetary  Assets".  This  statement  addresses the  measurement  of
          exchanges of nonmonetary assets and eliminates the exception from fair
          value  measurement  for  nonmonetary  exchanges of similar  productive
          assets and replaces it with an  exception  for  exchanges  that do not
          have  commercial  substance.  A  nonmonetary  exchange has  commercial
          substance  if the future  cash flows of the  entity  are  expected  to
          change  significantly  as a result of the exchange.  This Statement is
          effective for periods  beginning  after June 15, 2005. The adoption of
          this new accounting  pronouncement does  not  have  an impact  on  the
          Company's consolidated financial statements.

7.   Acquisition of Tangshan Yian
     ----------------------------

     On January 26, 2004,  Sinovac  acquired 100% of the shares of Tangshan Yian
     from a director (the "Vendor") of the Company by issuing  3,500,000  common
     shares and paying  $2,200,000  cash in the form of a promissory  note.  The
     $2,200,000 promissory note is non-interest bearing and payable on or before
     January 26, 2005 (note 11e). In connection with the acquisition, the Vendor
     agreed to assume and pay off $1 million of debt owed by Tangshan Yian on or
     before January 31, 2006. 1,500,000 of 3,500,000 shares are placed in escrow
     and contingently  cancellable if the debt is not paid within the given time
     frame.  Accordingly,  these escrow shares are excluded from the calculation
     of the weighted  average  number of shares for purposes of earnings  (loss)
     per share.  The total  consideration,  not including the 1.5 million escrow
     shares,  is valued at $3.6  million.  The share price used to determine the
     purchase  price for  accounting  purposes was based on the average  closing
     market  prices of the  Company's  common stock for the seven  trading days,
     which  includes  the three  trading  days before and after the  acquisition
     announcement on October 20, 2003.

     The acquisition has been accounted for by the purchase method with the fair
     value of the  consideration  paid being  allocated to the fair value of the
     identifiable assets and liabilities acquired as follows:

               Cash and cash equivalents                $       42,216
               Tangible assets                               6,445,222
               Liabilities                                  (2,877,395)

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

     Tangshan  Yian is in the business of research and  development,  production
     and  sales of  certain  pharmaceutical  products  in China.  The  operating
     results of Tangshan  Yian from  January  26, 2004 to December  31, 2004 are
     included in the  consolidated  statements of operations.  Tangshan Yian did
     not have material operations in 2003,  accordingly,  pro forma supplemental
     information on the results of operations of 2003 as though the  acquisition
     had been completed at the beginning of 2003 is not presented.

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

     (a)  The inactive hepatitis A drug license was contributed by Tangshan Yian
          in 2001 as its capital contribution to Sinovac Beijing.   The purchase
          price represented  Tangshan Yian's  book value and also  the estimated
          fair value at that time.  The  hepatitis  A vaccine  received  its new
          drug  certificate  from  the  SFDA  in  December  1999  and production
          commenced in July 2002.

     (b)  In March 2003, Sinovac China acquired the influenza virus  HA  vaccine
          drug license from  Tangshan  Yian at  the  vendor's cost.  In  January
          2004, Sinovac China completed the acquisition of 100% of the shares of
          Tangshan  Yian  (note 7).   Sinovac China  received  the  final   drug
          registration approval from the SFDA in February 2005.  The cost of the
          license was expensed as purchased in-process research and development.

     (c)  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, 2004,  $10,481  (December 31, 2003 -
          $10,487)  remained  unpaid and was recorded in due to related  parties
          (see note 11b).  Sinovac  China  received  a final  drug  registration
          approval from China SFDA in January 2005. The cost  of the license was
          expensed as purchased in-process research and  development.  The  drug
          license was acquired at the vendor's cost.

     (d)  Amortization expense for the licenses and permits was $194,326 for the
          year ended December 31, 2004 (2003 - $194,343 and 2002 - $194,188.

          The estimated  amortization  expenses for each of the five  succeeding
          fiscal years ended December 31 are as follows:

                    2005                           $194,000
                    2006                           $194,000
                    2007                           $194,000
                    2008                           $194,000
                    2009                           $194,000

          The above amortization expense forecast is an estimate. Actual amounts

10.  Income Taxes
     ------------

     Sinovac  China and  Tangshan  Yian are subject to income  taxes in China on
     their taxable income as reported in their statutory  accounts at a tax rate
     in  accordance  with the  relevant  income tax laws  applicable  to foreign
     investment enterprises. Tangshan Yian is eligible for a full exemption from
     income  taxes  for two years and a 50%  reduction  in income  taxes for the
     three years  following its first profit making year. The tax holiday has no
     impact on Tangshan Yian's  operating  results as Tangshan Yian was in a tax
     loss  position.  Sinovac  China is  granted a "New  Technology  Enterprise"
     certificate by Chinese government, under which Sinovac China is entitled to
     a tax holiday.  It was exempt from income taxes for three years until 2003,
     is  subject  to a 7.5%  corporation  income  tax  rate  until  2006 and 15%
     thereafter until it no longer  qualifies as a "New Technology  Enterprise".
     The parent company is not subject to income taxes.

     If the tax holiday of Sinovac China  described  above had not existed,  the
     income tax expenses (net of minority interest) would have been increased by
     approximately  $108,220  (RMB895,400) for the year ended December 31, 2004.
     Basic and diluted loss per common share would have been approximately $0.15
     for the year ended  December  31,  2004.  The tax  holiday had no impact on
     operating  results before taxes generated in 2003 and 2002 as Sinovac China
     was in a tax loss position.

     Income taxes are attributed to the operations in China and consist of:

10.  Income Taxes (continued)
     ------------

     The tax effects of temporary  differences  that give rise to the  Company's
     deferred tax assets (liabilities) are as follow:

     ---------------------------------------------------------------------------
                                                          2004              2003

     Tax losses carried forward                 $     422,000     $     139,000
     Excess of tax cost over the net book
     value of the certain long-lived assets           860,300           878,000
     Less: valuation allowance                       (422,000)       (1,017,000)
     ---------------------------------------------------------------------------

     Total deferred tax asset                   $     860,300     $           -
     ===========================================================================

     The  Company  determines  deferred taxes for each tax-paying entity in each
     tax jurisdiction.  The  potential  tax  benefits  arising  from  the losses
     incurred  by  Tangshan  Yian  have  not  been  recorded  in  the  financial
     statements,  however,  the  potential  benefits  arising  from  tax  losses
     incurred by Sinovac Beijing have been recognized.

     The  Company  evaluates  its  valuation allowance requirements on an annual
     basis by  reviewing reviews  all  available  evidence,  both  positive  and
     negative, and  considers  whether, based  on the weight of that evidence, a
     valuation allowance is needed. 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. The future realization of the  tax benefit  of
     an existing  deductible  temporary  difference  ultimately  depends  on the
     existence of sufficient taxable income of the appropriate  character within
     the carryforward period available under the tax law.

     With the history of  two  years  taxable  income  in Sinovac  Beijing,  the
     expectation of future earnings and the availability of certain tax planning
     strategies, the Company concluded that the valuation  allowance relating to
     timing differences in respect of long  lived  assets  should  be  reversed.
     Management expects that  taxable  income from operations in the future will
     be sufficient to utilize the  deductions  resulting  from  the  reversal of
     timing differences. If taxable income from operations  is  not  sufficient,
     the Company will employ tax planning strategies that relate the realization
     of gains on land use rights at the time that those  assets  are  no  longer
     required.

     Based on these factors, the Company concluded that a valuation allowance in
     respect of temporary timing differences  was  not  required at December 31,
     2004.  The  valuation  allowance  relating  to losses  carried  forward  of
     Tangshan Yian is still  required  as  realization  of  this  element of the
     potential tax benefit is still uncertain.

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

     effective  on  November 1,  2003,  pursuant to  which  directors, officers,
     employees and consultants of the Company are eligible to receive grants  of
     options for the Company's common stock.  The  Plan expires  on  November 1,
     2023.  A maximum of 5,000,000 common  stocks  have  been reserved under the
     plan.  Each stock option entitles its holder to  purchase  one common share
     of the Company.  Options may be granted for a term not exceeding  10  years
     from the date of grant.   The Plan is administered by the board of
     directors.

     its  directors,  officers and employees with an exercise price of $1.31 per
     share,  being the market price at the time of the grant. These options vest
     from April 1, 2004 to July 1, 2006 and expire on November 12, 2008.

     the 4,500 stock options  forfeited in 2004.  These options have an exercise
     price of $3.36 per share,  being the market price at the time of the grant,
     and expire on June 8, 2009. The options vest from June 9, 2004 to September

          3,800,000  units at a price of $1.25  per unit for gross  proceeds  of
          $4,750,000,  of which  $1,031,959  was  received by December 31, 2003.
          Each unit consists of one share of common stock of the Company and one

          The Company also issued 379,200 units as a finder's fee.

     (b)  Share Purchase Warrants

          As at December 31, 2004, there are warrants outstanding to purchase up
          to  7,366,618  shares of common stock of the  Company.  In  particular
          there are 3,187,418 share purchase warrants outstanding;  each warrant
          entitles  the  holder to  purchase  one  share of common  stock of the
          Company at $1.65 per share  until  January  15,  2005 with an exercise
          price increasing by $0.05 every month thereafter until April 15, 2005,
          and a  "piggyback"  right to purchase one  additional  share of common
          stock at $3.00 per share  until  November  14, 2005 only if the holder
          exercises the share purchase warrant.  In 2004, 991,782 share purchase
          warrants were exercised and as at December 31, 2004, there are 991,782

14.  Distribution of Profit
     ----------------------

     Pursuant to Chinese company law applicable to foreign investment companies,
     the Company's  subsidiaries,  Sinovac China and Tangshan Yian, are required
     to maintain  dedicated  reserves,  which  include a general  reserve and an
     enterprise expansion reserve. The dedicated reserves are to be appropriated
     from  net  income  after  taxes,  determined  under  the  relevant  Chinese
     accounting  regulations  at a rate  determined by the board of directors of
     the respective  subsidiaries,  and recorded as a component of shareholders'
     equity.  The  dedicated  reserves  are not  distributable  other  than upon
     liquidation.

     For the year ended December 31, 2004, Sinovac China appropriated 10% of its
     after-tax  profit,   determined  under  the  relevant  Chinese   accounting
     regulations,  to each of the general  reserve and the enterprise  expansion
     reserve.  As Sinovac China  recorded a loss for the year ended December 31,
     2003 and 2002, no appropriation to the dedicated reserves was made.

     Pursuant to the same Chinese  company law, the Company's  subsidiaries  are
     required  to  transfer,  at the  discretion  of its board of  directors,  a
     certain amount of its annual net income after taxes as determined under the
     relevant Chinese accounting  regulations to a staff welfare and bonus fund.
     For the year ended  December  31,  2004,  the board of directors of Sinovac
     China approved  $49,901 (RMB 413,183) for  contribution  to such fund which
     shall be utilized for  collective  staff benefits such as building of staff
     quarters or housing. As Sinovac China recorded a net loss for the years end
     December 31, 2003 and 2002, no appropriation to the staff welfare and bonus
     fund was made.  The amounts  appropriated  to staff  welfare and bonus fund
     were charged  against income and the related  provisions  were reflected as
     accrued liabilities in the consolidated balance sheets.

     Tangshan Yian recorded a net loss for each of the three years in the period
     ended December 31, 2004, so no appropriation to the dedicated  reserves and
     staff welfare and bonus fund was made.

     Dividends  declared  by  the  Company's   subsidiaries  are  based  on  the
     distributable  profits as reported in their statutory financial statements.
     As of December 31, 2004, dividends payable of $470,301 represent a minority
     interest in the share of dividends declared by Sinovac China.

17.  Subsequent Events
     -----------------

     (a)  On  November  30,  2004,  the  Company  entered  into  share  purchase
          agreements with  non-controlling  shareholders  to acquire  aggregated
          additional 20.56% interest in Sinovac China for cash  consideration of
          $3.31 million  increasing  the Company's  interest in Sinovac China to
          71.56%.  As of December 31, 2004, the Company made prepayments of $2.2
          million to the minority interest of Sinovac China. The transaction was
          completed in February  2005 and the Company is in process of valuation
          of certain  intangible  assets,  thus the  allocation  of the purchase
          price has not been finalized as at the report date.

     (b)  Subsequent  to  the  year  end,  the  Company  completed  two  private
          placements by issuing 491,667 and 70,000 units, respectively, at $3.00
          per unit for total gross proceeds of $1,685,000, of which $206,950 was
          received  by December  31,  2004.  Each unit  consists of one share of
          common  stock of the  Company  and one  share  purchase  warrant.  The
          Company issued 39,333 warrants and 1,970 warrants as finders' fees for
          the two  private  placements,  respectively.  The  Company  also  paid
          finders' fees in cash  totaling  $168,200.  Each warrant  entitles its
          holder to purchase one additional share of common stock of the Company
          at $3.35 per share until the one year  anniversary  date from the date
          of issuance, and:

          o    for the first  private  placement  warrants,  at a price of $4.00
               thereafter   until  the  two  year  anniversary  date  after  the
               issuance. The warrants are subject to call provisions in favor of
               the Company, which may reduce the expiry date

          o    for the second private  placement  warrants,  at a price of $4.00
               thereafter  until  October 15, 2006.  The warrants are subject to
               call  provisions  in favor of the  Company,  which may reduce the
               expiry date.

          Warrants  issued as the  finders' fee have the same terms as described
          above.

     (c)  Subsequent to the year end,  1,166,529  share  purchase  warrants were
          exercised  with  total  gross  proceeds  of  $1,916,266  and 1,166,529
          piggyback warrants were granted  to  the holders  upon the exercise of
          the original share purchase warrants.
