Ursus Offshore, Ltd., a corporation organized under the laws of Grand Cayman
island ("Ursus") hereby amends and supplements its Report on Schedule 13D,
originally filed on February 20, 2003 (the "Schedule 13D") with respect to the
common stock, no par value per share (the "Common Stock"), of Aradigm
Corporation (the "Issuer"). Capitalized terms used herein which are not
otherwise defined have the meanings ascribed to them in the Schedule 13D.

ITEM 2. IDENTITY AND BACKGROUND.

The following paragraph is added after the last paragraph of Item 4:

The obligations under the Voting Agreement have been terminated in accordance
with its terms and therefore Ursus and the Other Shareholders may no longer be
considered a Group for the purposes of Regulation 13D of the Act.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

The obligations under the Voting Agreement have been terminated in accordance
with its terms and as a result Ursus and the Other Shareholders may no longer be
considered a Group for the purposes of Regulation 13D of the Act. Accordingly,
Ursus may no longer be deemed to beneficially own the Other Shareholders
Securities.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER.

The following paragraph is added after the last paragraph of Item 6:

The obligations under the Voting Agreement have been terminated in accordance
with its terms and the transactions pursuant to the Financing Purchase Agreement
and the Warrant Repricing Agreement were consummated on March 10, 2003. Ursus
and the Other Shareholders may no longer be considered a Group and Ursus
disclaims any membership in such a Group. Upon termination of the Voting
Agreement and consummation of the Financing, Ursus is a direct beneficial owner
of less than 5% of the Issuer's Common Stock and is therefore not subject to the
reporting obligations under Section 13(d) of the Act.





                                    SIGNATURE

      After reasonable inquiry and to the best of its knowledge and belief, each
of the undersigned certifies that the information set forth in this statement is
true, complete and correct.

Date: March 14, 2003

                                             URSUS OFFSHORE LTD.
