The forgoing notwithstanding, in the case in which Otsuka, in its reasonable judgment, believes Dr. Kubota has ceased to act as an ongoing, active member of the Planning Team or the Implementation Team (the “Activity Cessation”), prior to exercising any of its rights under this Section 2.3 on account of such Activity Cessation, Otsuka shall notify Dr. Kubota in writing of its belief and permit Dr. Kubota a period of fifteen (15) days from receipt of such notice from Otsuka the opportunity to resume acting as an ongoing, active member of the Planning Team or the Implementation Team, as applicable, within such fifteen (15) day period. If Dr. Kubota resumes acting as an ongoing, active member of the Planning Team or the Implementation Team, as applicable, Otsuka shall not be permitted to exercise its rights under this Section 2.3 for such Activity Cessation.

Notwithstanding the foregoing, there shall be excluded from the foregoing definition of Confidential Information any of the foregoing that:

(a) either before or after the date of the disclosure to the Receiving Party is lawfully disclosed to the Receiving Party by Third Parties without any violation of any obligation to the Disclosing Party; or

In addition, the Receiving Party may disclose the Confidential Information of the Disclosing Party to the limited extent the Receiving Party is required to do so to comply with applicable Laws, to defend or prosecute litigation or to comply with governmental regulations or the regulations or requirements of any stock exchange, provided that the Receiving Party promptly provides prior notice of such disclosure to the Disclosing Party, cooperates with the Disclosing Party, and otherwise uses reasonable efforts to avoid or minimize the degree of such disclosure (including, without limitation, seeking a protective order or submitting a confidential treatment request, as applicable).

8.3 Conflict of Interest. The Parties recognize that any pharmaceutical or biotechnology company other than Otsuka may, by virtue of its equity investment to Acucela or its financial or other contribution to Acucela, have the right to appoint one or more directors or officers of Acucela in the future. In such event, if one or more directors or officers of Acucela are appointed by any such pharmaceutical or biotechnology company, then Acucela shall strictly prevent any such appointed directors or officers from accessing any Confidential Information of Otsuka or any data, information or materials related to Compound and Product or the subject matter of this Agreement.

Execution Copy September 4, 2008

(e) the infringement or alleged infringement of any Third Party’s Intellectual Property Rights as a result of the manufacture, use or sale of the Products or Compounds.

For purposes of this Article X, “Acucela Parties” means Acucela, its Affiliates and their respective licensors, agents, consultants, directors, officers, employees and shareholders.

The indemnification obligations set forth in this Section 10.1 shall not apply to the extent that any Loss (i) is the result of a breach of this Agreement by Acucela or the gross negligence or willful misconduct of any of the Acucela Parties; or (ii) is otherwise within the scope of the indemnification obligations set forth in Section 10.2 below.

10.2 Indemnification in Favor of Otsuka.

10.3 General Indemnification Procedures.

(a) A Person seeking indemnification pursuant to this Article X (an “Indemnified Party”) shall give prompt notice to the Party from whom such indemnification is sought (the “Indemnifying Party”) of the commencement or assertion of any Third Party Claim in respect of which indemnity may be sought hereunder, shall give the Indemnifying Party such information with respect to any indemnified Third Party Claim as the Indemnifying Party may reasonably request, and shall not make any admission concerning any such Third Party Claim, unless such admission is required by applicable Law or legal process, including, without limitation, in response to questions presented in depositions or interrogatories. Any admission made by the Indemnified Party with respect to any such Third Party Claim or the

Execution Copy September 4, 2008

failure to give such notice shall relieve the Indemnifying Party of any liability hereunder only to the extent that the ability of the Indemnifying Party to defend a Third Party Claim is prejudiced thereby (and no admission required by applicable Law or legal process shall be deemed to result in prejudice). The Indemnifying Party shall assume and conduct the defense of any Third Party Claim for which indemnification is sought, with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. Subject to the initial and continuing satisfaction of the terms and conditions of this Article X, the Indemnifying Party shall have full control of such Third Party Claim, including, without limitation, settlement negotiations and any legal proceedings. If the Indemnifying Party does not assume the defense of such Third Party Claim in accordance with this Section 10.3, the Indemnified Party may defend the Third Party Claim. If both Parties are Indemnifying Parties with respect to the same Third Party Claim, the Parties shall determine by mutual agreement, within twenty (20) days following their receipt of notice of commencement or assertion of such Third Party Claim (or such lesser period of time as may be required to respond properly to such claim), which Party shall assume the lead role in the defense thereof. Should the Indemnifying Parties be unable to mutually agree on which of them shall assume the lead role in the defense of such Third Party Claim, both Indemnifying Parties shall be entitled to participate in such defense through counsel of their respective choosing.

(b) Any Indemnified Party or Indemnifying Party not managing the defense of a Third Party Claim shall have the right to participate in (but not control), at its own expense (subject to the immediately succeeding sentence), the defense. The Party managing the defense of an action or proceeding under its control shall not be liable for any litigation cost or expense incurred, without its consent, by the Party not managing the defense; provided, however, that if the Indemnifying Party managing the defense fails to take reasonable steps necessary to defend such Third Party Claim, the Indemnified Party may assume its own defense, and the Indemnifying Party managing the defense will be liable for all reasonable costs or expenses paid or incurred in connection therewith; and provided further that, if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such Third Party Claim, the Indemnifying Party shall be responsible for the reasonable fees and expenses of counsel to the Indemnified Party solely in connection therewith.

(c) Without the prior written consent of the Indemnified Party, the Indemnifying Party shall not consent to a settlement of, or the entry of any judgment against an Indemnified Party arising from any such Third Party Claim to the extent such judgment or settlement involves (i) equitable or other non-monetary relief from the Indemnified Party, (ii) any monetary relief from the Indemnified Party not fully indemnified under this Agreement, or (iii) the assumption by the Indemnified Party of any liability. No Party shall, without the prior written consent of the other Party, enter into any compromise or settlement that commits the other Party to take, or to forbear to take, any action.

(d) The Parties shall cooperate in the defense or prosecution of any Third Party Claim and shall furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested in connection therewith.

Execution Copy September 4, 2008

(e) Any indemnification hereunder shall be made net of any insurance proceeds actually recovered by the Indemnified Party from unaffiliated Third Parties; provided, however, that if, following the payment to the Indemnified Party of any amount under this Article X, such Indemnified Party recovers any such insurance proceeds in respect of the claim for which such indemnification payment was made, the Indemnified Party shall promptly pay an amount equal to the amount of such proceeds (but not exceeding the amount of such net indemnification payment) to the Indemnifying Party. For the avoidance of doubt, the foregoing shall not be construed to require either Party to obtain any insurance not otherwise required under this Agreement or to first pursue an insurance recovery with respect to any matter for which the Indemnifying Party is otherwise obligated to indemnify the Indemnified Party under this Agreement.

(f) The Parties agree and acknowledge that the provisions of this Article X represent the Indemnified Party’s exclusive recourse with respect to any Losses for which indemnification is provided to the Indemnified Party under this Article X.

(b) If a Party disputes in good faith the existence or materiality of a material breach specified in a notice provided by the other Party pursuant to this Section 11.2 or any assertion by the other Party that such Party has failed to cure or diligently proceed to implement a plan to cure any such material breach, and, in each case, such Party provides notice to the other Party of such dispute within the applicable cure period, the other Party shall not have the right to terminate this Agreement unless and until the existence of such material breach or failure by such Party has been finally determined in accordance with Article XII.

“We are excited to broaden our strategic relationship with Otsuka through our work on this promising Phase III product,” commented Ryo Kubota, M.D., Ph.D., chief executive officer of Acucela. “Rebamipide has shown promising clinical activity in clinical trials to date and we believe the product has exceptional potential as a new therapy for the treatment of dry eye, one of the most common problems treated by optometrists,” added Dr. Kubota.

About Rebamipide Ophthalmic Suspension

Rebamipide is a novel compound synthesized by Otsuka Pharmaceutical Co., Ltd. Rebamipide ophthalmic suspension has a new mechanism of action, which is to increase the level of mucin in the tear covering the conjunctiva and cornea. It is expected to be effective in dry eye treatment by stabilizing the tear film and leading to improvement of the corneal-conjunctival damage associated with dry eye.

About Dry Eye

Dry eye syndrome is one of the most common problems treated by eye physicians. Over ten million Americans suffer from dry eyes. It is usually caused by a problem with the quality of the tear film that lubricates the eyes. Dry eye syndrome has many causes. One of the most common reasons for dryness is simply the normal aging process. As we grow older, our bodies produce less oil – 60 percent less at age 65 then at age 18. The oil deficiency also affects the tear film. Without as much oil to seal the watery layer, the tear film evaporates much faster, leaving dry areas on the cornea.

Founded in 1964, Otsuka Pharmaceutical Co., Ltd. is a global healthcare company with the corporate philosophy: ‘Otsuka-people creating new products for better health worldwide.’ Otsuka researches, develops, manufactures and markets innovative and original products, with a focus on pharmaceutical products for the treatment of diseases and consumer products for the maintenance of everyday health.
