FOR IMMEDIATE RELEASE


                      CYGNUS REPORTS 2004 FINANCIAL RESULTS

REDWOOD CITY, CA, MARCH 16, 2005 -- CYGNUS, INC. (OTC BULLETIN BOARD: CYGN)
today reported total revenues of $556,000 for the year ended December 31, 2004,
compared to $2.9 million for the year ended December 31, 2003. This decrease is
the result of the termination of the Company's Sales, Marketing and Distribution
Agreement with Sankyo Pharma Inc. in December 2003. Cygnus posted a net loss of
$8.1 million, or $0.20 per diluted share, for the year ended December 31, 2004,
compared to net income of $49.4 million, or $1.01 per diluted share, for the
year ended December 31, 2003. The net income for the year ended December 31,
2003 resulted from a gain of $75.8 million in the fourth quarter due to the
Company's settlement with Sankyo Pharma. Total costs and expenses for the year
ended December 31, 2004 were $11.6 million, compared to $27.0 million for the
year ended December 31, 2003. Costs of product revenues were $240,000 for the
year ended December 31, 2004, compared to $15.4 million for the year ended
December 31, 2003. The decrease in costs of product revenues for 2004 was
partially a result of the Company's reduced product revenues and suspension of
its manufacturing efforts. In addition, costs of product revenues for the year
ended December 31, 2003 included $5.3 million of underabsorbed indirect overhead
associated with building up the Company's manufacturing capacity to meet
then-expected future volumes and a write-off of approximately $6.4 million of
inventory. The Company did not have any research and development expenses for
the year ended December 31, 2004, compared to $5.1 million for the year ended
December 31, 2003. Cygnus ceased all research and development activities and
manufacturing in the fourth quarter of 2003. Sales, marketing, general and
administrative expenses for the year ended December 31, 2004 were $11.4 million,
compared to $6.4 million for the year ended December 31, 2003. This increase is
a result of maintaining personnel and capacity to resume manufacturing and
research and development activities if Cygnus were to have entered into a
strategic alliance or found an acquiror for the Company.

On December 16, 2004, Cygnus entered into an Asset Purchase Agreement with
Animas for the sale of substantially all of its assets (other than its cash and
cash equivalents, accounts receivable, and its claims in the arbitration matter
with Ortho-McNeil Pharmaceutical, Inc.), including its intellectual property
rights, product development and production equipment, regulatory package,
inventory and certain assumed contracts, including all supplier, manufacturing
and license agreements related to its products, to Animas for $10.0 million in
cash. Upon the closing of the asset sale to Animas, Cygnus will satisfy its
arbitration obligation to Sanofi-Aventis in order to release the Company's
assets, including its intellectual property, from the security interests that
Sanofi-Aventis has in those assets.

On February 9, 2005, Cygnus filed its definitive Proxy Statement on Schedule 14A
with the Securities and Exchange Commission (SEC) seeking stockholder approval
for the asset sale and for a Plan of Complete Liquidation and Dissolution. The
Special Meeting of Stockholders will be held on March 23, 2005. The Company
anticipates that the asset sale to Animas, if approved by the Company's
stockholders, will close in the first quarter of 2005. Additionally, Cygnus must
vacate its Redwood City, California, facility on or before March 31, 2005
pursuant to the Lease Termination Agreement with its landlord, executed on
December 16, 2004. Thereafter, it is anticipated that only two employees will
remain. The Company has rented office space in San Francisco, California, and
plans to pursue the Company's arbitration matter against Ortho-McNeil
Pharmaceutical Inc., a Johnson & Johnson company, and to wind down the Company.

As of December 31, 2004, Cygnus' cash and cash equivalents totaled $10.3
million. Also as of December 31, 2004, Cygnus had total liabilities of $12.7
million, of which $5.7 million were current liabilities. These balances included
amounts due to Sanofi-Aventis pursuant to the Company's remaining arbitration
obligation of $11.5 million, of which $4.5 million is due March 31, 2005. Under
the Company's renegotiated arbitration obligation with Sanofi-Aventis entered
into on January 27, 2005, the Company owes Sanofi-Aventis $4.5 million on March
31, 2005, rather than February 28, 2005; and $5.5 million at the time of the
closing of its asset sale to Animas, for a total of $10.0 million. In the event,
however, that the Company has not paid this $5.5 million prior to February 28,
2006, then Cygnus will owe $4.0 million at that time to Sanofi-Aventis and $3.0
million on February 28, 2007, for a total of $11.5 million.

The Company's Form 10-K for the year ended December 31, 2004 was filed with the
SEC on March 16, 2005. The Report of the Independent Registered Public
Accounting Firm, which is part of the Company's Form 10-K, highlights the
Company's condition in a going concern qualification in paragraph four thereof.
