2.1 Overview. The goal of the Development Program is to develop the New Product. Each party’s obligations under the Development Program shall be as set forth in this Section 2.1 or as agreed in writing by the parties after the Effective Date. Each party shall use commercially reasonable efforts to timely conduct its obligations under the Development Programs in accordance with the Development Plan. Subject to Medicis’ payment of the amount set forth in Section 6.1, each party shall bear its own costs to conduct its obligations under the Development Program. Impax shall use commercially reasonable efforts to use its proprietary technology in existence as of the Effective Date to formulate a product that meets or approaches the Target Product Profile and to perform standard in vitro analytic testing upon such resulting New Product to determine whether it meets the Target Product Profile criteria. Without limiting the generality of the foregoing, Impax shall perform no more than three (3) in vivo pharmacokinetic studies upon such New Product to determine whether it meets the Target Product Profile criteria. Impax shall also provide a reasonable amount of technical advice to Medicis with respect to pre-clinical manufacturing scale up work for the New Product.

Impax shall not incorporate any know-how, patented technology or other intellectual property Controlled by Impax into the New Product, the New Product Technology or the manufacturing process therefor without notifying Medicis in writing. If Medicis notifies Impax in writing, within thirty (30) days of Impax’s notice, that Medicis, based on its freedom to operate analysis, has a good faith concern that the use of such know-how, technology or intellectual property with respect to the New Product may infringe the intellectual property of a Third Party, then the parties will discuss such matter and, if such discussion does not reasonably resolve Medicis’ concern, then Medicis will notify Impax in writing within thirty (30) days of such discussion and Impax, following receipt of such notice, will not incorporate such know-how, technology or intellectual property into the New Product.

2.2 Amendment of Development Plan. The Development Plan may be amended from time to time by mutual written agreement of the parties or by the Steering Committee pursuant to Section 2.3.1.

The Payee shall be solely responsible for its costs in

making any such audit, unless the Payee identifies a discrepancy in favor of the Payor in the calculation of the share of Gross Profit or royalty or other payment owed, as applicable, under this Agreement in any calendar year from those properly payable for that calendar year of five percent (5%) or greater, in which event the Payor shall be solely responsible for the reasonable cost of such audit and pay the Payee any underpayment.
