News Release                                               [ALLERGAN LETTERHEAD]



FOR IMMEDIATE RELEASE
- ---------------------

ALLERGAN AND INSPIRE ENTER INTO A COLLABORATION FOR THE DEVELOPMENT OF TWO NOVEL
                     COMPOUNDS FOR THE TREATMENT OF DRY EYE
  Inspire's INS365 & Allergan's RESTASIS(TM) in Phase III Clinical Development


IRVINE, California and DURHAM, North Carolina - June 27, 2001 - Allergan, Inc.
(NYSE: AGN) and Inspire Pharmaceuticals, Inc. (Nasdaq: ISPH) today announced
that they have entered into a collaboration to develop two novel therapeutic
treatments for dry eye. The licensing, development and marketing agreement
includes Inspire's INS365 Ophthalmic and Allergan's Restasis(TM) cyclosporine
ophthalmic emulsion, 0.05%, both in Phase III clinical development for dry eye.

Under the terms of the agreement, Allergan obtains an exclusive license to
develop and commercialize INS365 Ophthalmic worldwide, with the exception of
Japan, and nine other Asian Countries covered by Inspire's agreement with Santen
Pharmaceutical Co. Ltd. In return, Inspire will receive up to $39 million in
up-front and milestone payments, a co-promotion arrangement for INS365
Ophthalmic in the United States, and payments based on net sales. In addition,
Inspire will receive an option to co-promote Restasis(TM) in the United States
and royalties on global net sales of Allergan's Restasis(TM) excluding the
Japan, Taiwan, Korea, Hong Kong and Peoples' Republic of China markets. The
agreement also provides for potential co-promotion by Inspire of one or more of
Allergan's other marketed and future products in the U.S.

Dry eye is one of the most frequent patient complaints reported to
ophthalmologists and represents a significant unmet medical need. Approximately
9 million patients in the major

markets suffer from moderate-to-severe dry eye and there is currently no
FDA-approved therapeutic treatment for dry eye disease.

"Dry eye syndrome may lead to serious corneal damage, enhanced susceptibility to
ocular infection, and potentially, significant visual loss and blindness," said
David A. Sullivan, Ph.D., Chairman, Medical and Scientific Advisory Board of the
Sjogren's Syndrome Foundation. "This strategic alliance between Allergan and
Inspire may well lead to the development of unique and effective therapies to
treat this currently incurable syndrome."

Restasis(TM) and INS365 Ophthalmic are being tested in separate Phase III
clinical trials for their ability to relieve the signs and symptoms of dry eye.
It is believed that the compounds have different mechanisms of action with
Restasis(TM) decreasing the underlying inflammation associated with dry eye and
INS365 Ophthalmic increasing the lubrication in the eye by stimulating natural
tear and mucin production to restore a healthier ocular surface.

 "Allergan is committed to being a leader in ophthalmology where the treatment
of dry eye represents a very large unmet medical need. The Inspire technology is
an excellent addition to Allergan's strong new product pipeline," said David
E.I. Pyott, Allergan's Chairman, Chief Executive Officer and President.
"Restasis(TM) and INS365 Ophthalmic are highly complementary products. Both
could be potential breakthroughs for the treatment of dry eye, each targeted to
a different patient need."

Greg Mossinghoff, Senior Vice President and Chief Business Officer for Inspire,
agrees, and also believes that the partnership is as complementary as the two
products. "We could not have found a better partner for INS365 Ophthalmic," said
Mr. Mossinghoff. "Allergan brings enormous expertise to the development of
ophthalmic products, and has tremendous commercial capability in this area.
Inspire plans to bolster this effort with our own salesforce, now in
development. Allergan is clearly a longstanding leader in the understanding and
treatment of dry eye."

condition involving abnormalities and deficiencies in the tear film due to a
variety of causes. Severe dry eye due to inflammation may result in serious
damage to the ocular surface. The incidence increases markedly with age and
after menopause in women. There are currently no FDA-approved pharmacologically
active treatments for dry eye.
