Common use of Expansion Program Clause in Contracts

Expansion Program. The parties have agreed on a pool of ten (10) compounds from ACADIA’s library of […***…] muscarinic selective compounds from which Allergan may chose a backup compound (the “[…***…] Expansion Program”). The current ten (10) compounds are listed on Exhibit A hereto (the “Back-up Pool”). The Research Term of the 2003 Agreement with respect to the […***…] Expansion Program shall be extended to cover the period beginning March 28, 2010 and ending March 27, 2011 (the “Additional Extension Period”). During the Additional Extension Period, ACADIA will provide information on compounds included in the Back-up Pool for continued evaluation by the parties. Further, if directed by the JRC (as defined below), ACADIA shall engage in the synthesis and evaluation of additional […***…] muscarinic selective compounds. Allergan may remove and add compounds to the Back-up Pool from (a) ACADIA’s existing […***…] muscarinic selective compounds (i.e., those identified prior to the Additional Extension Period), upon mutual agreement of the parties, or (b) from new compounds synthesized at the direction of the JRC, so long as the total number of compounds in the Back-up Pool does not exceed ten (10) at any given time. Allergan may select one compound from the Back-up Pool to be treated as a Collaboration Lead Compound (as defined in the 1999 Agreement and in addition to the compound based on […***…], which has been advanced by the parties pursuant to the 1999 Agreement) pursuant to the terms of the 1999 Agreement. Allergan shall use reasonable efforts to select a compound from the Back-up Pool to be treated as a second Collaboration Lead Compound prior to the end of the Additional Extension Period. Allergan’s right to so select a compound shall expire at the end of the Additional Extension Period. Upon selecting a compound from the Back-up Pool to be treated as a Collaboration Lead Compound, Allergan shall be entitled to select another compound to add to the Back-up Pool from (a) ACADIA’s existing […***…] muscarinic selective compounds (i.e., those identified prior to the Additional Extension Period), upon mutual agreement of the parties, or (b) from compounds synthesized at the direction of the JRC during the Additional Extension Period, so that Allergan retains ten (10) compounds within the Back-up Pool through the end of the Additional Extension Period. If Allergan selects a Back-up Pool compound to be treated as a Collaboration Lead Compound during the Additional Extension Period, then until one year after the end of the Additional Extension Period, Allergan may exchange such Collaboration Lead Compound for a compound within the Back-up Pool, which will then be treated as a Collaboration Lead Compound. Other than any such exchange, the Back-up Pool will not change after the end 2 ***Confidential Treatment Requested of the Additional Extension Period. Allergan shall have no rights to the compounds remaining in the Back-up Pool, or those compounds synthesized at the direction of the JRC that are not in the Back-up Pool, on the one-year anniversary of the end of the Additional Extension Period.

If Allergan selects a Back-up Pool compound to be treated as a Collaboration Lead Compound during the Additional Extension Period, then until one year after the end of the Additional Extension Period, Allergan may exchange such Collaboration Lead Compound for a compound within the Back-up Pool, which will then be treated as a Collaboration Lead Compound. Other than any such exchange, the Back-up Pool will not change after the end 2 ***Confidential Treatment Requested of the Additional Extension Period. Allergan shall have no rights to the compounds remaining in the Back-up Pool, or those compounds synthesized at the direction of the JRC that are not in the Back-up Pool, on the one-year anniversary of the end of the Additional Extension Period.
