                  share of Common Stock shall be entitled to receive cash for

                  the Common Stock as of June 28, 2004, not as of the date the
                  Certificate of Amendment was filed with the Delaware Secretary
                  of State.

                  4. Article IV Paragraph (A) of the Certificate is corrected to
                  read as follows:

                  "(A) CLASSES OF STOCK. This corporation is authorized to issue

                  Stock which this corporation is authorized to issue is ten
                  million (10,000,000). Effective as of 5:00 p.m., Eastern Time,
                  on June 28, 2004 (the "Effective Time") each three (3) shares
                  of this corporation's Common Stock, par value $0.0001 per
                  share, issued and outstanding shall, automatically and without
                  any action on the part of the respective holders thereof, be
                  combined and converted into one (1) share of Common Stock, par
                  value $0.0001 per share, of this corporation. No fractional
                  shares shall be issued and, in lieu thereof, any holder of
                  less than one share of Common Stock shall be entitled to
                  receive cash for such holder's fractional share based upon the
                  market price (as adjusted for the combination effected hereby)
                  of the Common Stock as of the Effective Time."
