 7.7 Publication. Any manuscript by Toray or Acologix (the “Publishing Party”) on

submission. In order to avoid loss of patent rights as a result of premature public disclosure of patentable information, the Reviewing Party shall notify
the Publishing Party in writing within [***] after receipt of any disclosure whether the Reviewing Party determines that a patent application should be filed to protect any invention disclosed in such scientific results. Any such patent or patent
application shall be subject to the terms and conditions of Section 6.2, 6.3 and 6.4. If a patent application is to be filed, the Publishing Party shall withhold publication or disclosure of such scientific results until the earlier of
(i) a patent application is filed thereon, (ii) the Parties determine after consultation that no patentable invention exists, or (iii) [***] after receipt by the Publishing Party of the Reviewing Party’s written notice of the
Reviewing Party’s desire to protect any potential invention. Further, if such scientific results contain the information of the other Party that is subject to use and nondisclosure restrictions under this ARTICLE 7, the Publishing Party shall
remove such information from the proposed publication or disclosure. 
 ARTICLE 8. 
 INDEMNIFICATION 
 8.1
Acologix Indemnity. Acologix shall indemnify, defend and hold harmless Toray and its Affiliates, and their respective officers, directors, employees, agents, licensors, and their respective successors, heirs and assigns and representatives,
from and against any and all claims, threatened claims, damages, losses, suits, proceedings, liabilities, costs (including, without limitation, reasonable legal expenses, costs of litigation and reasonable attorney’s fees) or judgments, whether
for money or equitable relief, of any kind, arising out of any claim, action, lawsuit or other proceeding brought by a Third Party (“Losses and Claims”) arising out of or relating, directly or indirectly, to (i) the performance of
the R&D Program by Acologix and its Affiliates, (ii) a breach by Acologix of its representations and warranties under this Agreement, or (iii) the negligence, recklessness or willful misconduct of Acologix; except where Losses and Claims
described in subsection (i) above (A) arise out of or relate, directly or indirectly, to a failure by Toray to comply with applicable law, rules or regulations, or (B) otherwise fall within the Losses and Claims described in Section 8.2 below.

 8.2 Toray Indemnity. Toray shall indemnify, defend and hold harmless Acologix and its Affiliates, and their respective officers,
directors, employees, agents, licensors, and their respective successors, heirs and assigns and representatives, from and against any and all Losses and Claims arising out of or relating, directly or indirectly, to: (i) the performance of the
R&D Program by Toray and its Affiliates; (ii) a breach by Toray of its representations and warranties under this Agreement, or (iii) the negligence, recklessness or willful misconduct of Toray; except where Losses and Claims described in
subsection (i) above (A) arise out of or relate, directly or indirectly, to a failure by Acologix to comply with applicable law, rules or regulations or (B) otherwise fall within the Losses and Claims described in Section 8.1 above. 
 8.3 Indemnification Procedure. A claim to which indemnification applies under Section 8.1 or 8.2 shall be referred to herein as an
“Indemnification Claim”. If any person or persons (collectively, the “Indemnitee”) intends to claim indemnification under this ARTICLE 8, the Indemnitee shall notify the other Party (the “Indemnitor”) in writing
promptly upon becoming aware of any claim that may be an Indemnification Claim (it being understood and agreed, however, that the failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under
this Agreement except and only to the extent that the Indemnitor is actually prejudiced as a result of such failure to give notice). The Indemnitor shall have the right to assume and control the defense of the Indemnification Claim at its own
expense with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee, provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if
representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party represented by such counsel in such proceedings. If the
Indemnitor does not assume the defense of the Indemnification Claim as aforesaid, the Indemnitee may defend the Indemnification Claim but shall have no obligation to do so. The Indemnitee shall not settle or compromise the Indemnification Claim
without the prior written consent of the Indemnitor, and the Indemnitor shall not settle or compromise the

 CONFIDENTIAL 
  
 
Indemnification Claim in any manner which would have an adverse effect on the Indemnitee’s interests (including without limitation any rights under this
Agreement or the scope or enforceability of the Indemnitee’s patents or know how), without the prior written consent of the Indemnitee, which consent, in each case, shall not be unreasonably withheld or delayed. The Indemnitee shall reasonably
cooperate with the Indemnitor at the Indemnitor’s expense and shall make available to the Indemnitor all pertinent information under the control of the Indemnitee, which information shall be subject to ARTICLE 7. 
 ARTICLE 9. 
 REPRESENTATIONS AND
WARRANTIES 
 9.1 Acologix Warranties. Acologix warrants to Toray that: (i) subject to the terms of the UCL Agreement, it has
the right to grant a license under the Acologix Patents as granted in this Agreement; (ii) it has the full right and authority to enter into this Agreement and to perform its obligations under this Agreement; (iii) it has not previously granted and
will not grant during the Term any rights or licenses in conflict with the rights and licenses granted in this Agreement. 
 9.2 Toray
Warranties. Toray warrants to Acologix that it has the right and authority to enter into this Agreement and to perform its obligations under this Agreement.

MATTER, AND ACOLOGIX SPECIFICALLY DISCLAIMS ANY AND ALL IMPLIED REPRESENTATIONS AND WARRANTIES, INCLUDING ANY WARRANTY OF MERCHANTABILTY, FITNESS FOR A PARTICULAR PURPOSE OR VALIDITY OR NON-INFRINGEMENT OF THE LICENSED SUBJECT MATTER. 
 ARTICLE 10. 
 DISPUTE RESOLUTION

 10.1 Escalation to Senior Executives. Other than pursuit of equitable relief as provided in Section 10.3, in the event
of a dispute or matter of significant concern arises between the Parties, then at the request of either Party, the matter shall be escalated to the CEO of Acologix and the senior executive at Toray with responsibility for pharmaceutical products and
authority to make a decision on behalf of the respective Party with respect to such matter. Upon such request, such senior executives shall make themselves reasonably available to meet, and shall meet either by telephone or if, specifically
requested, in person, to attempt to resolve such matter, and shall thereafter continue to use good faith efforts to attempt to resolve such matter unless it becomes clear that the matter cannot be resolved by mutual agreement. Thereafter, either
Party may initiate arbitration pursuant to Section 10.2 below upon written notice to the other Party.

 CONFIDENTIAL 
  
 10.2 Arbitration of Disputes. Other than pursuit of equitable relief as provided in Section 10.3, the Parties shall resolve disputes in
accordance with this Section 10.2. 
 (a) Within [***] after receipt of such notice, the Parties shall designate in writing a single
arbitrator to resolve the dispute; provided, however, that if the Parties cannot agree on an arbitrator within such [***] period, the arbitrator shall be selected by the Santa Clara, California office of the American Arbitration Association
(“AAA”) if the notice is issued by Toray or by the Tokyo office of the Japan Commercial Arbitration Association (“JCAA”) if the notice is issued by Acologix. The arbitrator shall be a lawyer knowledgeable and experienced in the
applicable laws concerning the subject matter of the dispute, who has experience and expertise in the worldwide development and commercialization of pharmaceuticals (including the partnering and licensing thereof) and the business, legal and
scientific considerations related thereto. In any case the arbitrator shall not be an Affiliate, employee, consultant, officer, director or stockholder of either Party, or otherwise have any current or previous relationship with either Party or
their respective Affiliates. The governing law in Section 11.1 shall govern any such proceedings. Any arbitration conducted under this Section 10.2 shall take place in Santa Clara if initiated by Toray or Tokyo if initiated by Acologix or
such other location as may be agreed by the Parties, and shall be conducted in English. 
 (b) Within [***] after the designation of the
arbitrator, the arbitrator and the Parties shall meet, and each Party shall provide to the arbitrator a written summary of all disputed issues, such Party’s position on such disputed issues and such Party’s proposed ruling on the merits of
each such issue. The arbitrator shall set a date for a hearing, which shall be no later than [***] after the submission of written proposals pursuant to the preceding sentence, for the presentation of evidence and legal argument concerning each of
the issues identified by the Parties. The Parties shall have the right to be represented by counsel. Except as provided herein, the arbitration shall be governed by the Rules of Arbitration of the AAA or JCAA, as the case may be, applicable at the
time of the notice of arbitration pursuant to Section 10.2(b); provided, however, that the Federal Rules of Evidence shall apply with regard to the admissibility of evidence in such hearing. The arbitrator shall use his or her best
efforts to rule on each disputed issue within [***] after completion of such hearing. The determination of the arbitrator as to the resolution of any dispute shall be binding and conclusive upon all Parties. All rulings of the arbitrator shall be in
writing and shall be delivered to the Parties except to the extent that the applicable arbitration rules provide otherwise. Nothing contained herein shall be construed to permit the arbitrator to award punitive, exemplary or any similar damages.

 (c) The (i) attorneys’ fees of the Parties in any arbitration, (ii) fees of the arbitrator and (iii) costs and
expenses of the arbitration shall be borne by the Parties in a proportion determined by the arbitrator. Any arbitration award hereunder may be entered in and enforced by any court of competent jurisdiction. 
 10.3 Injunctive Relief. This ARTICLE 10 shall not be construed to prohibit either Party from seeking preliminary or permanent injunctive relief,
restraining order or degree of specific performance in any court of competent jurisdiction to the extent not prohibited by this Agreement. For avoidance of doubt, any such equitable remedies provided under this ARTICLE 10 shall be cumulative and not
exclusive and are in addition to any other remedies, which either Party may have under this Agreement or applicable law.
