 12. DISPUTE RESOLUTION 
 12.1 Dispute Resolution. In the event of any dispute arising out of or relating to this Agreement, except as otherwise provided in
Section 2.3 of this Agreement, the parties shall, through their respective Executive Officers, first meet and attempt to resolve the dispute in face-to-face negotiations. This meeting shall occur within fifteen (15) calendar days after
either party provides notice to the other party that it wishes to invoke such negotiations. If the parties are unable to resolve such dispute through such negotiations, then, except in the case of a dispute, controversy or claim that concerns
(a) the validity or infringement of a patent, trademark or copyright, or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory, the dispute shall be resolved by binding arbitration before a single
independent and neutral experienced arbitrator selected by mutual agreement of the parties. In the event that the parties are unable to mutually agree on the appointment of such arbitrator, then such arbitration shall be conducted before a panel of
three independent and neutral experienced arbitrators, one chosen by ACADIA, one chosen by MSK and the third chosen by the foregoing two arbitrators. Any such arbitration proceeding, which arises out of Section 2.3(c) of this Agreement, shall
be administered by the American Arbitration Association, with limited discovery, in accordance with its then current rules governing commercial disputes and the place of arbitration shall be Honolulu, Hawaii. Any other arbitration (i.e., one not
arising under Section 2.3(c)), (A) if initiated by MSK, such arbitration proceeding shall be administered by the American Arbitration Association, with limited discovery, in accordance with its then current rules governing commercial
disputes and the place of arbitration shall be San Diego or (B) if initiated by ACADIA, such arbitration proceeding shall be administered by the Japan Commercial Arbitration Association , with limited discovery, in accordance with its then
current rules governing commercial disputes and the place of arbitration shall be Tokyo, Japan. Any arbitration shall be conducted in the English language and applicable arbitration association shall use California law as the governing law for this
Agreement and the parties’ obligations hereunder. The arbitrator(s) shall have no authority to award punitive or any other type of damages not measured by a party’s compensatory damages. Except to the extent necessary to confirm or enforce
an award or as may be required by law, neither a party nor any arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both MSK and ACADIA. In no event shall an arbitration be initiated after
the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable California statute of limitations. Each party shall bear its own attorneys’ fees, costs and disbursements
arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrators; provided, however, that the arbitrators shall be authorized to determine whether a party is the prevailing party, and if so, to award to that
prevailing party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.) and/or the fees and costs of the arbitrators. Each
party agrees to fully perform and satisfy any arbitration award made against it within fifteen (15) calendar days of the service of the award. By agreeing to this binding arbitration provision, the parties understand that they are waiving
certain rights and protections which may otherwise be available if a dispute between the parties were determined by litigation in court, including the right to seek or obtain certain types of damages precluded by this provision, the right to a jury
trial, certain rights of appeal and a right to invoke formal rules of procedure and evidence.

 12.2 Injunctive Relief. Notwithstanding the provisions of Section 12.1,
each party acknowledges and agrees that, due to the unique and valuable nature of the other party’s proprietary information and materials, there can be no adequate remedy at law for any breach by such party of the provisions of this Agreement,
that any such breach may result in irreparable harm to the other party for which monetary damages would be inadequate to compensate such party and that the other party shall have the right, in addition to any other rights available under applicable
law, to obtain from any court of competent jurisdiction injunctive relief to restrain any breach or threatened breach of, or otherwise to specifically enforce, any covenant or obligation of such party under such provisions, without the necessity of
posting any bond or security.

 FORM OF JOINT PRESS RELEASE 
 ACADIA PHARMACEUTICALS AND MEIJI SEIKA KAISHA FORM 
 COLLABORATION TO DEVELOP AND COMMERCIALIZE A 
 NEW CLASS OF PRO-COGNITIVE SCHIZOPHRENIA DRUGS 
 Meiji Seika Granted Rights to Develop and Commercialize Products in Asian
Territory; 
 ACADIA Retains All Rights in the Rest of the World 
 SAN DIEGO, CA March     , 2009 – ACADIA Pharmaceuticals Inc. (Nasdaq: ACAD) and Meiji Seika Kaisha, Ltd. (TSE: 2202) today announced that they have
established a collaboration to develop and commercialize a novel class of pro-cognitive drugs to treat patients with schizophrenia and related disorders in Japan and several other Asian countries. The collaboration will focus on developing a product
candidate, which was discovered by ACADIA and has been nominated by the parties for IND-track development. 
 “We are very pleased to be
working with ACADIA having strong expertise within CNS drug discovery. We trust this collaboration will boost our portfolio of psychiatric products, a strategic therapeutic focus area for Meiji Seika.” said Osamu Makabe, Ph.D., Senior Vice
President, Research and Development of Meiji Seika. “The exciting profile of this class of drugs may offer a promising new approach to treating schizophrenia and related disorders, including the potential to address cognitive disturbances
frequently experienced by these patients, which represents an area of major unmet medical need.” 
 “We are delighted to establish
this innovative partnership with Meiji Seika,” said Uli Hacksell, Ph.D., Chief Executive Officer of ACADIA. “With its strong development and commercial capabilities and focus on CNS disorders, we believe Meiji Seika is an excellent partner
to help advance the development of this exciting program and to commercialize in Japan and other Asian markets.”

 The collaboration is based on a novel class of compounds that combine muscarinic m1 agonism with
dopamine and serotonin receptor antagonism. These compounds have demonstrated a unique combination of pro-cognitive and antipsychotic activity in preclinical behavioral models. The companies plan to initiate IND-enabling studies and co-develop a
product candidate through completion of proof-of-concept clinical studies. Meiji Seika has exclusive rights to develop and commercialize the product in Japan and several other Asian countries. ACADIA retains the right to develop and commercialize
the product in the rest of the world, including the U.S. and Europe. Pursuant to the terms of the agreement, ACADIA is eligible to receive from Meiji Seika up to $25 million in aggregate payments, including upfront fees, and development and
regulatory milestone payments, as well as royalties on product sales in the Asian territory, if the product is commercialized successfully. Meiji Seika is responsible for the initial development expenses up to a specified level and the companies
will share the remaining expenses through clinical proof-of-concept. Meiji Seika is responsible for all costs associated with the development, manufacturing and commercialization of the product in the Asian territory after proof-of-concept. Meiji
Seika is eligible to share a portion of any product-related revenues received by ACADIA in the rest of the world. 
 About Schizophrenia

 Schizophrenia is a chronic, debilitating mental illness characterized by disturbances in thinking, emotional reaction, and behavior.
Approximately one percent of the population develops schizophrenia during their lifetime and more than two million people in the United States suffer from this disease. Disturbances associated with schizophrenia may include positive symptoms, such
as hallucinations and delusions, and a range of negative symptoms, including loss of interest and emotional withdrawal, as well as cognitive disturbances. It is believed that cognitive disturbances prevent patients with schizophrenia from
readjusting to society. As a result, patients with schizophrenia are normally required to be under medical care for their entire lives. Currently prescribed treatments do not effectively address or may exacerbate cognitive disturbances associated
with schizophrenia.
