ITEM 1.  CHANGES IN CONTROL OF REGISTRANT.

Effective March 11, 2004, pursuant to the Agreement and Plan of Merger (the
"Merger Agreement"), dated January 28, 2004, among privately held DeliaTroph
Pharmaceuticals, Inc. dba Hyalozyme Therapeutics, Inc. ("Halozyme"), Global
Yacht Services, Inc. ("Global"), a publicly traded Nevada corporation and
Hyalozyme Acquisition Corporation ("Merger Sub"), a wholly owned subsidiary of
Global, the Merger Sub merged with and into Halozyme, with Halozyme remaining as
the surviving corporation (the "Merger").

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

The following summary lists 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 Merger Agreement, Halozyme raised
           equity capital of approximately $8.1 million.

o          The shareholders of Global amended and restated Global's Articles of
           Incorporation to change Global'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          Global issued 35,521,906 shares of its restricted common stock,
           6,380,397 options and 11,742,665 warrants to purchase shares of its
           common stock to the shareholders of Halozyme in exchange for 100% of
           their issued and outstanding common stock, options and warrants to
           purchase Halozyme's common stock.

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

o          Global's shareholders own approximately 10% of the issued and
           outstanding shares of Halozyme's common stock, based on 39,421,906
           shares outstanding after the Merger.

The full text of the Merger Agreement may be found at Exhibit A to Global
Yacht's definitive Schedule 14C Information Statement, as filed with the
Securities and Exchange Commission on February 17, 2004.

The Merger has been treated as a re-capitalization of Halozyme. Accordingly, the
financial statements reflect the historical activity of Haloyzme with the
capital structure of Global. Prior to the Merger, Global had limited operations.
On March 11, 2004, Global changed its name to Halozyme Therapeutics, Inc.
