ITEM 1. CHANGES IN CONTROL OF REGISTRANT.

Effective March 11, 2004, pursuant to the Agreement and Plan of Merger (the
"Merger Agreement"), dated as of January 28, 2004, among privately held
DeliaTroph Pharmaceuticals, Inc. dba Hyalozyme Therapeutics, Inc. ("Halozyme"),
Global Yacht Services, Inc., a publicly traded Nevada corporation ("Global") and
Hyalozyme Acquisition Corporation, a wholly owned subsidiary of Global ("Merger
Sub"), 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 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, 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 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 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 38,899,701
            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.
