        RIBOZYME PHARMACEUTICALS SIGNS AGREEMENT TO SECURE $48 MILLION IN
            FINANCING TO SUPPORT THE DEVELOPMENT OF RNAI THERAPEUTICS


BOULDER, CO - FEBRUARY 12, 2003 - Ribozyme Pharmaceuticals, Inc. (RPI) (Nasdaq:
RZYM) announced today that it has entered into a definitive agreement for the
sale of $48 million in common stock and warrants to purchase common stock to The
Sprout Group, Venrock Associates, Oxford Bioscience Partners, Techno Venture
Management and Granite Global Ventures. The financing will support RPI's RNA
interference (RNAi) therapeutic development platform, which will be the
centerpiece of the company's future activities.

RNAi is a mechanism used by the body to regulate the expression of genes and the
replication of viruses. This mechanism is mediated by small interfering RNA
molecules. RPI has shown that it can use stabilized small interfering RNA
molecules to down-regulate the expression of many genes without affecting other
genes. Using this RNA expertise, RPI is developing RNAi-based therapeutics that
selectively target disease-causing genes and viruses. Harnessing the natural
process of RNAi holds the potential to create a new class of drugs with
unrivalled specificity toward a wide range of diseases. The journal SCIENCE
recently voted the discovery of small RNA molecules, and their role in RNA
interference, the 2002 scientific Breakthrough of the Year.

"In the last 18 months we have expanded our leadership position in nucleic acid
technology and developed a powerful RNAi therapeutic platform," commented Howard
W. Robin, President and CEO of RPI. "This infusion of funding by prominent
venture capital firms is an endorsement of our work in RNAi. The proceeds of
this financing will be used to accelerate our research programs to expeditiously
advance products to the clinic. The recent surge in interest in RNAi,
exemplified by several key scientific publications, further emphasizes the
potential of this rapidly advancing technology. Upon completion of this
financing and consistent with our new vision for the company, RPI will change
its name to reflect our focus on the development of RNAi-based therapeutics."

Dr. Douglas Fambrough of Oxford Bioscience Partners said, "Because of its
potential for treating disease, RNAi is perhaps the most important molecular
biology discovery of the last decade. This investment in RPI's internal skills
and capabilities puts them in an ideal position to realize the goal of bringing
RNAi-based therapeutics to the market."

The investors will have the right to appoint four designees to RPI's Board of
Directors. These appointments, along with their stock ownership, will provide
the investors with a controlling interest in the company.

Raymond James & Associates, Inc. served as the financial advisor to RPI for this
transaction.

The issuance of the securities is subject to approval by RPI's stockholders and
to the satisfaction of a number of closing conditions. In addition to approving
the terms of the private placement, RPI stockholders will be asked to approve a
number of other matters, including a reverse stock split, a name change, and an
increase in shares authorized for option issuances and employee benefit
programs. RPI intends to obtain stockholder approval by April 30, 2003.

In connection with the transaction, RPI also has agreed to offer existing
stockholders non-transferable rights to purchase up to $5 million of newly
issued common stock at the same purchase price paid by the investors. This
offering will permit existing stockholders to increase their participation in
the company's future.

THE RIGHTS OFFERING WILL BE MADE ONLY BY MEANS OF A PROSPECTUS FILED AS PART OF
A REGISTRATION STATEMENT WITH THE SECURITIES AND EXCHANGE COMMISSION.

A REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS NOT YET BEEN FILED
WITH THE SECURITIES AND EXCHANGE COMMISSION. THE SECURITIES MAY NOT BE SOLD NOR
MAY ANY OFFER TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT
HAS BEEN FILED AND BECOME EFFECTIVE. THIS PRESS RELEASE SHALL NOT CONSTITUTE AN

OF THESE SECURITIES IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD
BE UNLAWFUL PRIOR TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF
SUCH STATE OR JURISDICTION.
