                       NASTECH ACQUIRES ATOSSA HEALTHCARE
                  TO EXPAND NASAL PRODUCT DEVELOPMENT PROGRAMS

                        DR. STEVEN QUAY, OF ATOSSA, NAMED
                     CHAIRMAN, PRESIDENT AND CEO OF NASTECH-

Hauppauge, New York, August 9, 2000 - Nastech Pharmaceutical Company, Inc.
(Nasdaq: NSTK), today announced that the Company has acquired privately held
Atossa Healthcare, Inc. The acquisition is a strategic move designed to solidify
Nastech's position as a leader in the development of therapeutics that are
administered nasally. The merger also enables the Company to develop new
capabilities in the area of women's health beginning with the further
development of Atossa's lead breast cancer diagnostic product. Financial terms
of the agreement were not disclosed.

Nastech also announced today that under the terms of the agreement Steven C.
Quay, M.D., Ph.D., the founder of Atossa Healthcare, will join the Company as
Chairman, President and Chief Executive Officer.

"We are excited about the acquisition of Atossa because it provides Nastech with
a tremendous leverage opportunity and synergy within our core competency," said
Devin Wenig, director and member of Nastech's Executive Committee. "This
opportunity is exemplified by Atossa's breast cancer risk assessment test, and
Nastech's key programs in pain management and sexual dysfunction - all of which
rely on nasal delivery. We are also delighted to welcome Steven Quay at this
exciting time for Nastech. His proven expertise and leadership will enable us to
accelerate our clinical programs and commercialize our products."

"I am truly pleased about the opportunity to join Nastech and to help the
company solidify its position in the nasal drug delivery arena," said Dr. Quay.
"The ability to combine the strengths of Nastech and Atossa and to use those
strengths to build a portfolio of safe, efficacious and fast-acting nasally
administered pharmaceuticals, including small molecules, peptides and
macromolecules, is a challenge I am eager to undertake."

Atossa, based in Washington State, is focused on the development of a
proprietary platform of diagnostics and treatments related to breast cancer risk
assessment and therapeutics and other women's health care products. The
Company's lead product is a diagnostic test currently being evaluated for its
ability to identify patients who are at high risk for breast cancer.

Key strengths of the combined company include:

      o     One of Nastech's two commercially available, FDA-approved products,
            Stadol NS(R) (butorphanol tartrate) - a pharmaceutical to treat
            moderate to severe pain, including migraine headache pain - is
            marketed in the United States by Bristol Meyers Squibb. Nastech
            receives royalties on sales. The company recently began a clinical
            development program on a new, faster-acting formulation of
            butorphanol tartrate.


      o     Nastech's other FDA-approved product, Nascobal, is indicated for the
            treatment of pernicious anemia and other vitamin B-12 deficiencies,
            including during treatment for cancer. Schwarz Pharma Inc. markets
            Nascobal in the United States, and Nastech is paid to manufacture
            Nascobal and also receives royalties on sales. Nascobal is awaiting
            market approval in Europe.

      o     Nastech's product portfolio encompasses several exciting therapeutic
            areas, including pain management, sexual dysfunction and motion
            sickness. Products in development include intranasal scopolamine for
            motion sickness (Phase III), intranasal apomorphine for male sexual
            dysfunction (Phase II), intranasal morphine for the treatment of
            moderate to severe pain, including breakthrough pain (Phase II), and
            intranasal butorphanol for the treatment of acute migraine pain
            (Phase II). Atossa's breast cancer product brings Nastech into the
            women's health market.

      o     The company has state-of-the-art research laboratories and an
            FDA-approved manufacturing facility, allowing rapid development
            timelines.
