         b) In  the  Certificate  of  Amendment  of  the  Amended  and  Restated

amendment inadvertently was set forth incorrectly, therefore,

         Paragraphs  FIRST and FIFTH of the Amended and Restated  Certificate of
Incorporation should be corrected to read as follows:

         "FIRST:  That  at a  meeting  of the  Board  of  Directors  of  CALYPTE

amendment  to be  advisable  and calling a meeting of the  stockholders  of said
corporation for consideration thereof. The resolution setting forth the proposed
amendment is as follows:

         RESOLVED, that the Amended and Restated Certificate of Incorporation of
this  corporation  be amended by  changing  the first  paragraph  of the Article
thereof  numbered  "IV",  so that,  as  amended,  said  paragraph  shall read as
follows:



         `IV:
                  The  corporation  is authorized to issue two classes of shares
of stock to be  designated,  respectively,  Common Stock,  $0.03 par value,  and

         IT IS FURTHER  RESOLVED  that  CALYPTE  BIOMEDICAL  CORPORATION  be and
hereby is authorized and directed to cause a one for thirty (1:30) reverse stock
split of the issued and  outstanding  Common  Shares,  which reverse stock split
shall  decrease the number of issued and  outstanding  shares of Common Stock by
one-thirtieth,  but shall have no effect on the 800,000,000 shares of authorized
Common Stock."

         "FIFTH:  That said amendment shall become effective on May 28, 2003."

         IN WITNESS WHEREOF,  I have hereunto set my hand and seal this 27th day
