authorized  Common Stock of Sinovac  Biotech  Ltd.  (the  "Company").  The total
amount of shares  authorized  by the  Company's  Articles  of  Incorporation  is
150,000,000. Of these, 100,000,000 are Common Stock and 50,000,000 are Preferred
Stock.  There has been no issuance of any  Preferred  Stock.  Dividend,  voting,
conversion  rights,  liquidation rights and other rights of the Preferred Stock,
if any, will be established by the Board of Directors upon issuance.

     Holders of the Common  Stock are  entitled  to cast one vote for each share
held at all shareholder  meetings for all purposes,  except that in the election
of Directors, each shareholder of Common Stock shall have as many votes for each
share held by him as there are  directors  to be elected and for whose  election
the shareholder has a right to vote. There are no preemptive  rights  associated
with the  securities  and no cumulative  voting is authorized by the Articles of
Incorporation or the By-Laws.

     The Company has never  declared or paid cash  dividends on the Common Stock
of the Company.  Management intends to retain all available funds and any future
