Section 3.2 of the Amended and Restated Bylaws of Halozyme Therapeutics, Inc.
("Halozyme") was amended in its entirety by the Halozyme Board of Directors on
June 29, 2005 to read as follows:

3.2 NUMBER OF DIRECTORS.

The Board of Directors shall consist of not fewer than four (4) nor more than
nine (9) persons. The exact number of directors shall be six (6) until changed,
within the limits specified above, by a bylaw amending this Section 3.2, duly
adopted by the Board of Directors or by the stockholders. The indefinite number
of directors may be changed, or a definite number may be fixed without provision
for an indefinite number, by a duly adopted amendment to the Articles of
Incorporation or by an amendment to this bylaw duly adopted by the vote or
written consent of holders of a majority of the outstanding shares entitled to
vote. No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.
