During such [confidential treatment requested] period and, if INSPIRE notifies ALLERGAN of its willingness to enter into such an agreement on comparable or more favorable terms, ALLERGAN agrees to cease negotiations with the Third Party regarding the Proposal and INSPIRE and ALLERGAN shall promptly commence good faith negotiations, for a period of up to [confidential treatment requested], in an effort to reach a mutually acceptable definitive agreement for such marketing and promotion arrangement (a “Definitive Agreement”).

3.10.2 If, despite each party’s good faith efforts, ALLERGAN and INSPIRE are not able to reach agreement on and do not execute a Definitive Agreement within such [confidential treatment requested] period, ALLERGAN shall be free to enter into such an agreement regarding such licensing arrangement; provided, however, that the terms and conditions of any agreement with a Third Party taken as a whole shall be no more favorable to such Third Party than the material terms and conditions last offered by INSPIRE during the parties’ good faith negotiations.

3.10.3 If INSPIRE fails to contact ALLERGAN within the [confidential treatment requested] period or notifies ALLERGAN that it does not wish to enter into an agreement to market, promote and/or detail Elestat outside the Field of Use in the Territory under any terms, ALLERGAN may proceed to enter into an agreement with the Third Party signatory of the Proposal or any other Third Party. If, however, INSPIRE

notifies ALLERGAN that it is interested in acquiring the rights to market, promote and/or detail Elestat outside the Field of Use in the Territory but not on the terms set forth in the Proposal, ALLERGAN may proceed to enter into an agreement with the Third Party signatory of the Proposal; provided, however, that the material terms and conditions of any agreement with such Third Party taken as a whole shall be consistent with and in no case more favorable to such Third Party than the terms and conditions set forth in the original Proposal.

3.10.4 ALLERGAN shall promptly notify INSPIRE upon the execution of any agreement with a Third Party to market, promote and/or detail Elestat outside the Field of Use in the Territory, and shall provide a copy of the signed agreement to INSPIRE upon its request if: (1) the parties were unable to reach agreement on a Definitive Agreement under Section 3.10.2; or (2) INSPIRE, under Section 3.10.3, notifies ALLERGAN of its interest in obtaining such rights, but not on the terms set forth in the Proposal.

3.10.5 If, upon any expiration or waiver of the right of first refusal set forth in this Section 3.10, ALLERGAN enters into an agreement with any Third Party to market, promote and/or detail Elestat outside the Field of Use in the Territory, INSPIRE’s compensation hereunder shall be calculated based on Revised Net Sales in accordance with the provisions of Section 4.1.3.

3.11 INSPIRE Responsibilities. INSPIRE will work collaboratively with ALLERGAN through the JCC in connection with the marketing of Elestat in the Territory and, in addition to the rights and responsibilities set forth elsewhere in this Agreement, INSPIRE shall:

3.11.1 Use commercially reasonable efforts to commercialize Elestat in the Territory. In connection therewith, INSPIRE shall dedicate resources to the commercialization of Elestat consistent with the resources that INSPIRE, at all relevant times, would dedicate to products containing compounds with similar commercial potential to Elestat that were generated from INSPIRE’s own research efforts and that INSPIRE decided to develop commercially and market.

3.11.2 Use commercially reasonable efforts and proceed diligently to launch Elestat in the Territory as soon as possible, and in no case later than forty-five (45) days after the later of: (1) the first physical shipment of Elestat to the trade by ALLERGAN; or (2) January 1, 2004; and to perform such obligations by using, without limitation, a Sales Force with sufficient skills and experience, together with sufficient equipment and facilities.

3.11.3 INSPIRE shall, at its expense, supervise, train and maintain such competent and qualified sales representatives as may be required to promote and detail Elestat as provided herein and in the Marketing Plans, such training to include a reasonable proficiency examination for all sales representatives who will be engaged in detailing. ALLERGAN will provide reasonable assistance in the training at the launch meeting and assimilation of training materials at its expense.

3.11.4 INSPIRE shall use commercially reasonable efforts to achieve at least fifty percent (50%) of the applicable annual Net Sales forecast set forth on Schedule B, provided there have been no material stock outages (i.e., no backorders for Elestat over thirty (30) days in any Commercial Year) during such period and subject to ALLERGAN’s performance of its obligations under Section 3.9.2.

3.11.5 Commencing with the second Calendar Quarter of 2004, INSPIRE shall furnish to ALLERGAN on or before the forty-fifth (45th) day of each Calendar Quarter, a summary of information coming to INSPIRE’s attention in the Territory concerning introductions and promotional activities of products competitive with Elestat.

3.11.6 Within thirty (30) days of the Effective Date, and thereafter, by the seventh (7^th) calendar day of each month, INSPIRE shall provide ALLERGAN with a good faith eighteen (18) month rolling forecast by month of estimated unit sales of Elestat in the Territory, which forecast shall, for the avoidance of doubt (and as applicable), update and supercede the forecast set forth in the Marketing Plans.

3.11.7 At ALLERGAN’s request, INSPIRE shall provide ALLERGAN with copies of any written communications disseminated by INSPIRE generally to its Sales Force relating to marketing and promotion strategy for Elestat.

References to the receiving party in this Article 11 refer to INSPIRE and its Affiliates, if any, on the one hand, and ALLERGAN and its Affiliates, on the other hand, as the case may be.

11.1.5 Notwithstanding anything in this Agreement to the contrary, ALLERGAN shall not be obligated to provide INSPIRE with any technical information or data, including but not limited to, technical information relating to Elestat, including but not limited to, information and data relating to formulation, and analytical methods relating to Elestat, unless such technical information is already in the public domain.

11.2 Obligation to Maintain Confidentiality of Information. INSPIRE and ALLERGAN each hereby covenants not to use Confidential Information, or any part thereof, except for the purposes of this Agreement. In addition, each receiving party shall keep all Confidential Information in complete confidence and shall not disclose or make such Confidential Information, or any part thereof, available to Third Parties except:

11.2.1 In the case of ALLERGAN, for the purpose of obtaining and maintaining any necessary Regulatory Approvals for the sale of Elestat under this Agreement in the Territory;

11.2.2 To the extent that the disclosing party may agree in writing, such agreement to be obtained prior to any disclosure by receiving party;

11.2.3 To the extent that such Confidential Information can be demonstrated by written records to be known to the receiving party or its Affiliates at the time of receipt thereof from the disclosing party;

11.2.4 To the extent that such Confidential Information is or may become a matter of public knowledge other than through any act or omission of the receiving party or its Affiliates in breach of this Agreement; or

11.2.5 To the extent required by law, statute, rule or court order, including, without limitation, by the rules and regulations of the Securities and Exchange Commission, to be disclosed (the disclosing party shall, however, use reasonable efforts to obtain confidential treatment of any such disclosure, consult with the other party and permit the other party to participate in seeking an appropriate protective order). INSPIRE acknowledges that sales reports received by INSPIRE from ALLERGAN pursuant to Section 3.9.3 are subject to the restrictions of Section 3.9.3.

11.3 Information Disclosed Prior to Effective Date. Section 11.2 above shall also apply to the Information relating to the subject matter of this Agreement disclosed by a party or its Affiliates to the other party or its Affiliates prior to the Effective Date of this Agreement.

11.4 Survival of Obligation. Obligations under this Article 11 shall be in force during the term of this Agreement and any extension hereof and shall survive expiration or termination (as the case may be) of this Agreement for a period of [confidential treatment requested].

11.5 Injunctive Relief. The parties hereto acknowledge that either party’s breach of this Article 11 may cause the other party irreparable injury for which it would not have an adequate remedy at law. In the event of a breach, the non-breaching party shall be entitled to injunctive relief in addition to any other remedies it may have at law or in equity.

ALLERGAN AND INSPIRE ENTER INTO COLLABORATION

TO CO-PROMOTE ELESTAT^™ IN THE U.S.

IRVINE, Calif. and DURHAM, North Carolina – December 8, 2003 – Allergan, Inc. (NYSE: AGN) and Inspire Pharmaceuticals, Inc. (Nasdaq: ISPH) today announced that they have entered into a co-promotion agreement in the United States for Elestat^™ (epinastine HCL ophthalmic solution 0.05%) within the ophthalmic specialty area. Elestat^™ was approved by the U.S. Food & Drug Administration in October 2003 for the prevention of itching associated with allergic conjunctivitis.

Under the terms of the agreement, Inspire will provide Allergan with an up-front payment and Allergan will pay a royalty to Inspire on Elestat^™ net sales. In addition, this agreement calls for Allergan to significantly reduce its existing royalty payment to Inspire for Restasis^® (cyclosporine ophthalmic emulsion 0.05%), that is covered by a previous agreement between Allergan and Inspire.

Inspire will have the primary responsibility for selling, promotional and marketing activities related to Elestat^™, and will incur associated costs. Allergan and Inspire will work collaboratively on overall product strategy and management.

Allergan will record Elestat^™ sales and retain all other product costs and licensing rights. Allergan will also maintain responsibility for all international marketing and selling activities and expects to launch Elestat^™ in Europe under the brand name Relestat^™ in early 2004.

▇▇▇▇▇ ▇▇▇▇▇, Allergan’s Chairman, President and Chief Executive Officer said: “With four new Allergan Eye Care products approved in the last 12 months, this partnership with Inspire for Elestat^™ will allow Allergan to focus its sales and marketing organization on its key business drivers: Lumigan®, (bimatoprost ophthalmic solution 0.03%) Restasis®, Zymar^™ (gatifloxacin ophthalmic solution 0.3%), and Acular LS® (ketorolac tromethamine ophthalmic solution 0.5%) while maximizing the value of this recently approved technology with a high quality company such as Inspire.”

▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Ph.D., Chief Executive Officer of Inspire, said, “Inspire has made significant progress in building its ophthalmology sales and marketing organization and will have a first-rate force in place to launch Elestat^™ in the first quarter of 2004. This will be the first product launch for Inspire – a major milestone for our growing company as we prepare for the potential approval of diquafosol.”

Schedule C-1

Elestat^™, a topical antihistamine with mast cell stabilizing and anti-inflammatory activity, is licensed from Boehringer-Ingelheim and was developed by Allergan for the relief of ocular itching associated with ocular allergies. Its multi-action effects inhibit binding to both H1 and H2 receptors, while preventing recruitment and activation of pro-inflammatory mediators that can trigger and exacerbate the allergic response. Elestat^™ has a rapid onset of action, and in pivotal clinical trials was well tolerated by patients and demonstrated a favorable safety profile. The most frequently reported ocular side effects occurring in approximately 1-10% of patients included burning sensation in the eye, folliculosis, hyperemia and pruritus. The annual U.S. market for ocular allergy approximates $325 million, with a strong growth rate of 23%. (Source: IMS – the market and growth rate information is a moving annual total as of the end of June 2003.)
