              The funds  used to acquire  the  Company's  Common  Stock were Mr.

              Hyalozyme    Therapeutics,    Inc.,   a   California   corporation
              ("Hyalozyme").

 ITEM 4.      PURPOSE OF TRANSACTION.

              Effective  March 11, 2004,  pursuant to the  Agreement and Plan of
              Merger (the  "Merger  Agreement"),  dated as of January 28,  2004,
              among  Hyalozyme,  the  Company  (formerly  known as Global  Yacht
              Services,  Inc.) and Hyalozyme Acquisition  Corporation,  a wholly
              owned  subsidiary of the Company  ("Merger  Sub"),  the Merger Sub
              merged with and into  Halozyme,  with  Halozyme  remaining  as the
              surviving corporation (the "Merger").

              Although the Company acquired Hyalozyme as a result of the Merger,
              the  shareholders  of  Hyalozyme  hold a  majority  of the  voting
              interest  in the  combined  enterprise.  Additionally,  the Merger
              resulted in Hyalozyme's management and Board of Directors assuming
              operational control of the Company.

              The  following  lists a summary of the structure of the Merger and
              matters completed in connection therewith:



              o      On  January  28,  2004,  pursuant  to an  investment  round
                     completed  simultaneously  with the  signing  of the Merger
                     Agreement, Hyalozyme raised equity capital of approximately
                     $8.1 million.

              o      The  shareholders  of the Company  amended and restated the
                     Company's Articles of Incorporation to change the Company's
                     corporate name to Halozyme  Therapeutics,  Inc.,  increased
                     the  authorized  number of  shares  of Common  Stock to 100
                     million  and  authorized  20  million  shares of  preferred
                     stock.

              o      The  Company  issued  34,999,701  shares of its  restricted
                     Common Stock,  6,886,807 options and 11,758,460 warrants to
                     purchase shares of its Common Stock to the  shareholders of
                     Hyalozyme   in  exchange  for  100%  of  their  issued  and
                     outstanding common stock,  options and warrants to purchase
                     Hyalozyme's common stock.

              o      A total of 4,296,362  shares of the  Company's  outstanding
                     Common  Stock  were  redeemed  by the  Company  from  three
                     shareholders  in exchange  for  $42,303,  or  approximately
                     $0.01 per share.

              o      The   Company's   shareholders   before   the   Merger  own
                     approximately  10% of the issued and outstanding  shares of
                     the  Company's  Common Stock,  based on  38,899,701  shares
                     outstanding after the Merger.
