 NALTREXONE HYDROCHLORIDE SUPPLY AGREEMENT 
 This
Naltrexone Hydrochloride Supply Agreement (this “Agreement”) is made as of this day of January 5, 2009 (the “Effective Date”) by and among OREXIGEN THERAPEUTICS, INC. (“OREXIGEN”), a
Delaware corporation located at 3344 N. Torrey Pines Court, Suite 200, La Jolla, CA 92037, and CILAG GMBH INTERNATIONAL (“CILAG”), a corporation of Switzerland located at Landis+Gyr-Strasse 1, 6300 Zug, Switzerland. 
 WHEREAS, CILAG is a manufacturer of Naltrexone Hydrochloride and wishes to manufacture and supply Naltrexone Hydrochloride to OREXIGEN on the terms described herein; and

 WHEREAS, OREXIGEN desires a supply of commercial quantities of Naltrexone Hydrochloride on the terms described herein. 
 NOW, THEREFORE, in consideration of the mutual covenants set forth herein, CILAG and OREXIGEN (each, a “Party” and, collectively, the
“Parties”) agree as follows. 
  

	1.	SCOPE OF AGREEMENT 

  

	1.1.	This Agreement shall apply to all purchases of Naltrexone Hydrochloride by OREXIGEN from CILAG during the term of this Agreement. 

  

	1.2.	This Agreement does not constitute a purchase order. Purchases under this Agreement shall be made only with purchase orders issued by OREXIGEN to CILAG (each, a “Purchase
Order”). Each Purchase Order shall set forth the information required by Section 3.3 and shall be in the form attached hereto as Appendix A. Purchase Order No. 1153 between the Parties dated January 2, 2008 shall be
deemed an accepted Purchase Order under and pursuant to the terms of this Agreement. All terms and conditions of the Purchase Orders shall apply, provided that in the event of a conflict or inconsistency between the terms of any Purchase Order,
order acknowledgement, invoice, shipping terms, packaging slip or other documentation, and the terms of this Agreement, the terms of this Agreement shall control and prevail and such additional or inconsistent terms are hereby expressly rejected,
unless such documentation specifically states that it overrides conflicting terms of this Agreement and is signed by each of the Parties. 

  

	1.3.	All Naltrexone Hydrochloride sold by CILAG to OREXIGEN will be manufactured by CILAG in accordance with the terms of this Agreement. 









	2.	MANUFACTURING; SPECIFICATIONS; QUALIFICATION OF SECOND SOURCE


  

	2.1.	CILAG shall manufacture the Naltrexone Hydrochloride supplied to OREXIGEN in accordance with (a) the specifications set forth on Schedule A attached hereto, and
(b) the specifications, methods, processes and procedures, including site of manufacture, set forth in CILAG’s drug master file (“DMF”) for Naltrexone Hydrochloride to be filed with the U.S. Food and Drug Administration
(“FDA”) pursuant to Section 2.3 (both (a) and (b), including any modifications approved in accordance with Section 2.2 collectively, the “Specifications”). If CILAG wishes to make any change to the
Specifications or manufacturing process (including, but not limited to, any change that could affect the purity, potency, identity and/or physical properties of the Naltrexone Hydrochloride or the site of its manufacture), it shall notify OREXIGEN
in writing in advance thereof and comply with the requirements of Section 2.2 prior to implementing such change. Such notification shall describe the proposed change in sufficient detail, including any corresponding increase or decrease in
manufacturing cost, so as to permit OREXIGEN to understand the reasons for the proposed change and to evaluate the impact of such change to oral formulations containing Naltrexone Hydrochloride (the “Finished Products”). OREXIGEN
may request from time to time that CILAG implement voluntary changes to the Specifications upon written request to CILAG. CILAG shall use commercially reasonably efforts to implement such request from OREXIGEN, which if carried out shall be at
OREXIGEN’s expense. In the event that a voluntary change to the Specifications is to be implemented, CILAG shall perform, at OREXIGEN’s expense, all analytical or experimental work in connection with making any such changes, but OREXIGEN
shall be responsible, at its expense, for filing all changes proposed by OREXIGEN in connection with any regulatory approval, and for seeking approval of any such change required by each applicable Regulatory Agency (as defined in Section 2.2).


  

	2.2.	Without limiting the generality of the foregoing provisions, CILAG shall not change the Specifications unless [***], each having jurisdiction over Naltrexone Hydrochloride, the
Finished Products or OREXIGEN’s marketing of Finished Products (each a “Regulatory Agency”). If any change to the Specifications requires the approval of a Regulatory Agency, such change [***]. To the extent [***]. For the
avoidance of doubt, CILAG shall not supply to OREXIGEN hereunder, and OREXIGEN shall have no obligation to accept, any Naltrexone Hydrochloride from CILAG manufactured in contravention of this Section 2.2. 

  

	2.3.	 CILAG will take commercially reasonable steps necessary to enable OREXIGEN to secure from the relevant Regulatory Agencies approval of CILAG and any applicable
Second-Source Supplier (as defined in Section 2.5) as a source of supply of Naltrexone Hydrochloride for OREXIGEN’s Finished Products to be marketed anywhere in the world. Without limiting the generality of the foregoing, CILAG will supply
to OREXIGEN sufficient quantities of Naltrexone Hydrochloride to enable OREXIGEN to support the filing of one or more New Drug Applications (the “NDA”) (or Abbreviated New Drug Application (“ANDA”), if applicable),
together with all amendments and supplements thereto, referencing CILAG or any applicable Second-Source Supplier as its supplier of Naltrexone Hydrochloride for its initial Finished Product candidate. CILAG will be responsible for procuring and
maintaining all regulatory filings and any other compliance efforts, including without limitation,

the DMF, related to Naltrexone Hydrochloride that are required in order to obtain approval from the FDA of OREXIGEN’s NDAs (or ANDAs, if applicable)
referencing Naltrexone Hydrochloride and equivalent approvals from Regulatory Agencies in other jurisdictions, at no additional cost to OREXIGEN. CILAG shall file the DMF with the FDA and shall provide the DMF’s reference number in writing to
OREXIGEN at least [***] ([***] days prior to Orexigen’s filing of an NDA (or ANDA, if applicable). OREXIGEN shall have the right to reference the DMF in its NDAs (or ANDAs, if applicable) and equivalent approvals from Regulatory Agencies in
jurisdictions outside the United States, and the right to access the open part of the DMF. [***]. 


  

	2.4.	CILAG shall test, or have tested, each lot of Naltrexone Hydrochloride shipped to OREXIGEN using the analytical testing methodologies which are set forth in the Specifications in
order to assure the conformity of each lot of Naltrexone Hydrochloride supplied hereunder to the Specifications and all Applicable Laws (as defined in Section 8.1.1). With each shipment of Naltrexone Hydrochloride, CILAG shall deliver to
OREXIGEN certificates of analysis from CILAG (a) stating that the Naltrexone Hydrochloride being shipped has been tested and does conform to the Specifications, (b) setting forth in detail the testing methodology employed by CILAG in
making the foregoing determination and the results generated by such tests, and (c) confirming compliance with the current good manufacturing practices (“cGMP”) required by the FDA, and other relevant Regulatory Agencies in
those jurisdictions of which OREXIGEN has given CILAG notice, with respect to the manufacture and testing of Naltrexone Hydrochloride for use as an active pharmaceutical ingredient in the Finished Products and subsequent sale in such jurisdictions.


  

	2.5.	CILAG shall have the option, at its sole cost and expense and subject to the terms and conditions of this Agreement, to qualify one second-source supplier for Naltrexone
Hydrochloride (“Second-Source Suppler”). CILAG shall provide at least [***] ([***]) months prior written notice of its intent to so qualify a Second-Source Supplier. CILAG shall not implement the use of such Second-Source Supplier
until (i) OREXIGEN has approved such Second-Source Supplier, which approval shall not be unreasonably withheld, including the conduct by OREXIGEN of an audit of the Second-Source Supplier, and (ii) OREXIGEN has received the requisite
approvals from all applicable Regulatory Agencies to use such Second-Source Supplier. 

  

	3.	FORECASTS; FIRM COMMITMENT; PURCHASE ORDERS 

  

	3.1.	 In order to assist CILAG in planning the production runs for Naltrexone Hydrochloride, beginning at least [***] ([***]) year prior to OREXIGEN’s anticipated

Naltrexone Hydrochloride required by OREXIGEN, by month, for the following twelve (12) month period (the “Rolling Forecast”). OREXIGEN may, at its discretion, update such Rolling Forecast more frequently. The first [***]
([***]) months of each Rolling Forecast shall constitute a binding order on CILAG and OREXIGEN for the quantities of 



  


	***	Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.











	 	 
Naltrexone Hydrochloride specified therein (“Firm Commitment”), and the following [***] ([***]) months of the Rolling Forecast shall be
non-binding estimates and shall be used by CILAG for planning purposes only. CILAG shall be obligated to supply no less than [***] percent ([***]%) of the quantity of Naltrexone Hydrochloride ordered by OREXIGEN pursuant to any Purchase Order which
complies with Section 3.3. Further, CILAG agrees to use commercially reasonable efforts to deliver any quantities of Naltrexone Hydrochloride ordered by OREXIGEN which exceed OREXIGEN’s Rolling Forecast by not more than [***] percent
([***]%) or for which a delivery date of less than [***] ([***]) days from the date of such Purchase Order is requested by OREXIGEN. 


  

	3.2.	After the Finished Products have received approval for marketing from a Regulatory Agency and have been made generally commercially available (hereinafter “Commercial
Launch”), CILAG shall, within [***] ([***]) business days after OREXIGEN has provided its quarterly forecast, notify OREXIGEN in writing of any prospective problems CILAG might have with respect to supplying OREXIGEN’s forecasted order
quantities. Upon receipt of such notice, the Parties shall promptly discuss the inability to supply the amounts forecasted by OREXIGEN and work in good faith to agree upon revised forecast amounts. Failing agreement, OREXIGEN’s last submitted
forecast shall be deemed to be the new quarterly forecast. The foregoing notice and discussion requirements of this Section 3.2 shall not operate to relieve CILAG of its obligations pursuant to any Firm Commitment Purchase Order (as defined in
Section 3.3), or affect OREXIGEN’s right to pursue any remedies that may be available to it. 

  

	3.3.	Prior to the beginning of each calendar quarter, OREXIGEN shall submit a binding, non-cancelable Purchase Order for the most recent Firm Commitment portion of the Rolling Forecast
for such calendar quarter (“Firm Commitment Purchase Order”). Each Purchase Order shall specify the quantity of Naltrexone Hydrochloride ordered, the total Price (as defined in Section 5.2) for such quantities of Naltrexone
Hydrochloride calculated in accordance with Section 5 hereof, and the required delivery date and destination, consistent with the terms of this Agreement. OREXIGEN shall submit each Purchase Order to CILAG at least [***] ([***]) days in advance
of the delivery date requested in the Purchase Order. Within [***] ([***]) business days after the date that a Purchase Order is submitted, CILAG shall acknowledge receipt of OREXIGEN’s Purchase Order and confirm that the amounts of Naltrexone
Hydrochloride ordered in the Purchase Order will be timely supplied. For the avoidance of doubt, CILAG shall be obligated to accept any such Purchase Order which complies with this Section 3.3. Notwithstanding the foregoing, any failure by
CILAG to respond to a Purchase Order within such [***] ([***]) day period shall be deemed acceptance of such Purchase Order. 

  

	3.4.	 CILAG agrees to retain at least a rolling [***] ([***]) month safety stock of Naltrexone Hydrochloride or intermediates to be used for sale by OREXIGEN based on the
average monthly quantities in the Rolling Forecast. CILAG will promptly notify OREXIGEN if CILAG’s manufacturing capacity will be insufficient to fill a Purchase Order submitted by OREXIGEN, and CILAG agrees that OREXIGEN shall receive [***] of
CILAG based upon OREXIGEN’s Rolling Forecast for Naltrexone Hydrochloride for the applicable quarter. Such notice will include the expected duration of the shortage and its impact on the 



  


	***	Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.











	 	 
supply of Naltrexone Hydrochloride to OREXIGEN. Such notification shall not operate to relieve CILAG of its obligations to deliver the ordered amounts of
Naltrexone Hydrochloride or affect OREXIGEN’s right to pursue any remedies that may be available to it. CILAG will use its best efforts to mitigate the impact on OREXIGEN of shortages or other constrained capacity. The obligations of CILAG to
maintain the safety stock specified herein shall commence as of the Commercial Launch. 


  

	3.5.	During any period during this Agreement in which CILAG, for any reason, including, without limitation, a force majeure as provided in Section 13.1, fails to deliver the
requisite quantities of Naltrexone Hydrochloride included within any Firm Commitment Purchase Order, within [***] ([***]) days after the date of delivery confirmed in writing by CILAG or if CILAG otherwise anticipates or notifies OREXIGEN that it
will be unable to make delivery of all or a portion of the ordered Naltrexone Hydrochloride within [***] ([***]) days after the confirmed date of delivery, then OREXIGEN may refuse such late shipment of Naltrexone Hydrochloride from CILAG and
purchase such quantities under such Firm Commitment Purchase Order through a substitute third party supplier. The quantity of Naltrexone Hydrochloride purchased from the substitute supplier due to CILAG’s failure to supply shall be treated as
if it were purchased from CILAG for purposes of determining the [***] in the table of Schedule B for subsequent purchase of Naltrexone Hydrochloride. In the event CILAG regains its ability to resume supplying hereunder, OREXIGEN’s right to
purchase Naltrexone Hydrochloride from the substitute supplier shall terminate immediately upon the delivery by CILAG to OREXIGEN of written notice thereof except in respect of orders already placed or obligated to be placed by OREXIGEN from the
substitute supplier. Notwithstanding CILAG’s reinstatement, if CILAG fails to timely meet its continuing manufacturing and supply obligations to OREXIGEN (consistent with all representations, warranties and covenants herein) on more than
[***] occasions during [***], then in addition to any termination rights hereunder, the Exclusivity Obligation (as defined in Section 5.1) shall be of no further force and effect with respect to OREXIGEN for [***] and [***], provided, however,
CILAG shall still be obligated to perform all of its obligations under this Agreement. 

  

	4.	DELIVERY

	***	Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.











	 	9.1.2.	any claim, complaint, suit, proceeding or cause of action against any of the Supplier Indemnitees alleging physical injury or death, brought by or on behalf of an injured party, or

Products; 

  

	 	9.1.3.	any negligence or willful misconduct of OREXIGEN, its employees, officers and directors in performing this Agreement; and

	 	9.2.1.	any misrepresentation, breach of warranty, or the nonfulfillment of any obligation, covenant, or duty on the part of CILAG under this Agreement; 

  

	 	9.2.2.	any claim, complaint, suit proceeding or cause of action against any of the OREXIGEN Indemnitees alleging physical injury or death, brought by or on behalf of an injured party, or
loss of service or consortium or a similar such claim, complaint, suit, proceeding or cause of action brought by a spouse, relative or companion of an injured party due to such physical injury or death, and in each case arising because Naltrexone
Hydrochloride supplied by CILAG to OREXIGEN did not meet the warranties in Section 8.1. 

  

	 	9.2.3.	any negligence or willful misconduct of CILAG or its employees, officers or directors in performing this Agreement; and 









	 	9.2.4.	any claim of patent infringement relating to the Naltrexone Hydrochloride supplied to OREXIGEN or the process for manufacturing the Naltrexone Hydrochloride supplied to OREXIGEN
which claim, if true, would be in contravention of the representations, warranties and covenants of CILAG hereunder; 

 except
to the extent resulting from (i) any misrepresentation, breach of warranty, or the non-fulfillment of any obligation, covenant, or duty on the part of OREXIGEN under this Agreement, (ii) any negligence or willful misconduct of the OREXIGEN
Indemnitees in performing this Agreement, or (iii) any claim subject to OREXIGEN’s indemnification obligations under Section 9.1. 
  

	9.3.	 The foregoing indemnification obligations are subject to the following: (a) the indemnifying Party must be notified by or on behalf of the indemnified Party in
writing promptly after a claim is made, a suit is filed or an action or investigation is initiated (each, a “Proceeding”) against the indemnified Party, unless such delay does not materially prejudice the indemnifying Party;
(b) subject to the provisions set forth below in this Section 9.3, the indemnifying Party shall be permitted to defend, control, conduct and prosecute, in the indemnifying Party’s sole discretion and by counsel of the indemnifying
Party’s choosing, the defense of such Proceeding brought against the indemnified Party; (c) the indemnifying Party shall have the right in its sole discretion to settle, compromise or otherwise terminate the Proceeding solely upon the
payment of money; provided, that, there is no finding or admission of any violation by any indemnified Party of (i) any law, rule or regulation or (ii) the rights of any person; and provided, further, that, no such settlement shall
prohibit any indemnified Party from importing the Naltrexone Hydrochloride into the United States or making, using or selling products in the United States made from such Naltrexone Hydrochloride; (d) the indemnified Party shall refrain from
settling (or endeavoring to settle, or entering into settlement negotiations with respect to) any such Proceeding without the indemnifying Party’s prior written consent; (e) except as may otherwise be required by law, the indemnified Party
shall not compromise the position of the indemnifying Party by admission, statements, disclosure or conduct (collectively, “Disclosure”) in a way that could prejudice the defense, control, conduct or prosecution of said cause of
action (it being understood that no indemnified Party shall be deemed to have violated this provision so long as such Party has acted in good faith to fulfill its obligations under this provision); and (f) the indemnified Party shall cooperate
with the indemnifying Party in the defense, conduct, prosecution or termination of the Proceeding, including the furnishing of information and the assistance from employees of the indemnified Party at the indemnifying Party’s reasonable request
and expense. With respect to clause (e) above, the indemnified Party will provide the indemnifying Party with prompt written notice in advance of any such Disclosure being made to permit the indemnifying Party to seek an appropriate protective
order, restriction on response or withdrawal of the request for Disclosure. If, however, any such request for relief by the indemnifying Party is denied or is otherwise unavailable, the relevant indemnified Party may make the Disclosure without any
liability to the indemnifying Party. The indemnified Party may, at its option and expense, participate in the indemnifying Party’s defense with counsel of its own choosing, and if the indemnified Party so participates, the Parties shall
cooperate with one another in such defense in a commercially reasonable 











	 	 
fashion. Notwithstanding any provision in this Agreement to the contrary, OREXIGEN shall at all times have the right to assume direction and control of the
defense of any claim alleging infringement, misappropriation or violation of any patent, trade secret or other intellectual property right of any third party, provided that OREXIGEN will provide CILAG with a reasonable opportunity to review and
consult from time to time concerning the strategy and action plan (including possibly pursuing one or more licenses as appropriate), and in such event CILAG shall cooperate and assist as requested in the defense of such claim and if OREXIGEN finds
it necessary or desirable to join CILAG as a party, CILAG shall execute all papers or perform such other acts as may reasonably be required by OREXIGEN. Further, CILAG shall not settle or consent to the entry of any judgment with respect to any such
claim, without OREXIGEN’s prior written consent. 


  

	9.4.	The indemnification rights provided for herein are in addition to, and not in substitution for, any and all remedies available to a Party under this Agreement or otherwise at law or
in equity. Notwithstanding anything to the contrary in this Section 9, each Party may, and expressly reserves the right to, seek judicial relief from any court of competent jurisdiction in order to obtain an injunction or other equitable
relief. 

  

	9.5.	IN NO EVENT SHALL ANY OF THE PARTIES HERETO BE RESPONSIBLE OR LIABLE TO THE OTHER UNDER ANY PROVISION OF THIS AGREEMENT OR UNDER ANY THEORY OF NEGLIGENCE, STRICT LIABILITY OR OTHER
LEGAL OR EQUITABLE THEORY, FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, OR EXEMPLARY DAMAGES OR LOST PROFITS. FOR THE PURPOSE OF CLARITY, NOTHING IN THIS SECTION IS INTENDED TO LIMIT THE INDEMNIFICATION OBLIGATIONS OF ANY PARTY WITH RESPECT TO THE
CHARACTERIZATION OF ANY CLAIM BY A THIRD PARTY AS CONSEQUENTIAL, INDIRECT, SPECIAL, OR EXEMPLARY DAMAGES OR LOST PROFITS. 









	10.	ADVERSE EVENT REPORTING; COSTS AND EXPENSES OF RECALL

has an obligation to report any Adverse Events to any Regulatory Agencies it may do so provided it first provides written notice to OREXIGEN thereof and a copy of such report. CILAG agrees to consider in good faith any comments OREXIGEN has timely
provided concerning such reports prior to CILAG’s submission of the same to the applicable Regulatory Agency. In the event CILAG (a) receives any information regarding any Adverse Event relating to Naltrexone Hydrochloride or any Finished
Products or their manufacture, (b) receives any complaints relating, or potentially relating, to Naltrexone Hydrochloride or any Finished Products or their manufacture, (c) receives any medical or technical inquiry relating, or potentially
relating, to Naltrexone Hydrochloride or any Finished Products or their manufacture, or (d) discovers or is notified of any material defect in Naltrexone Hydrochloride or any Finished Products, it shall (i) notify OREXIGEN within [***]
([***]) days thereof, and (ii) promptly conduct an investigation in accordance with its approved written procedures for the surveillance, receipt, evaluation, and reporting of complaints, inquiries or discoveries of that nature and report the
results of such investigation to OREXIGEN promptly upon the completion thereof. 

  

	10.2.	OREXIGEN shall have sole control and responsibility for conducting all voluntary and involuntary recalls or other related action (collectively, “Recalls”) of units
of any Finished Product; provided, however, that CILAG agrees to reimburse OREXIGEN for all of its reasonable costs and expenses incurred with respect to any Recalls arising out of any of the causes set forth in Sections 9.2.1 through 9.2.4.
Further, in the event of any Recall of any Finished Products arising out of any of the causes set forth in Sections 9.2.1 through 9.2.4, OREXIGEN’s obligation to pay CILAG for Naltrexone Hydrochloride purchased hereunder shall cease. This
Section 10 is intended to augment and not limit the indemnification provisions of Section 9 herein. 

  

	11.	TERM AND TERMINATION 

  

	11.1.	This Agreement shall commence on the Effective Date and shall continue in effect until the date that is four (4) years from the Qualification Date (the “Initial

	11.2.	This Agreement may be terminated by (i) OREXIGEN upon [***] ([***]) days written notice to CILAG of a failure by CILAG to perform or observe any material covenant, condition or
agreement to be performed or observed by it under this Agreement, unless such breach has been cured within the [***] ([***]) day notice period, and (ii) CILAG upon [***] ([***]) days written notice to OREXIGEN of a failure by OREXIGEN to
perform or observe any material covenant, condition or agreement to be performed or observed by it under this Agreement, unless such breach has been cured within the [***] ([***]) day notice period; provided, that if the breach by OREXIGEN is a
failure to pay an invoice when due (except as provided in Section 5.8), then the notice and cure period shall be [***] ([***]) days. 

  

	11.3.	OREXIGEN may terminate this Agreement effective immediately upon written notice to CILAG in the event that (a) CILAG dissolves, is declared insolvent or bankrupt by a court of
competent jurisdiction; (b) a voluntary or involuntary petition of bankruptcy is filed in any court of competent jurisdiction by CILAG; or (c) this Agreement is assigned by CILAG for the benefit of creditors. CILAG may terminate this
Agreement effective immediately upon written notice to OREXIGEN in the event that (a) OREXIGEN dissolves, is declared insolvent or bankrupt by a court of competent jurisdiction; (b) a voluntary or involuntary petition of bankruptcy is
filed in any court of competent jurisdiction by OREXIGEN; or (c) this Agreement is assigned by OREXIGEN for the benefit of creditors. 

  

	11.4.	OREXIGEN may terminate this Agreement effective immediately upon written notice to CILAG in the event that (a) any Regulatory Agency takes any action, or raises any objection,
that prevents OREXIGEN from importing, exporting, purchasing or selling either the Naltrexone Hydrochloride or the Finished Product; (b) the Finished Product fails during clinical trials and OREXIGEN withdraws its NDA; (c) OREXIGEN
determines, in its sole discretion, to no longer pursue the development and/or commercialization of a Finished Product which contains Naltrexone Hydrochloride; or (d) a legal proceeding shall be instituted against CILAG, which is reasonably
likely to materially adversely affect CILAG’s ability to properly perform under this Agreement or subject OREXIGEN to any material risk of liability or loss. 

  

	11.5.	In the event of termination of this Agreement by OREXIGEN pursuant to Section 11.4, OREXIGEN agrees to pay for previously placed orders of Naltrexone Hydrochloride but not yet
delivered to OREXIGEN, provided that CILAG shall use reasonable commercial efforts to mitigate the amount of such payments by OREXIGEN, including, but not limited to, selling such Naltrexone Hydrochloride to other customers, and provided further
that CILAG shall deliver Naltrexone Hydrochloride pursuant to such orders in accordance with this Agreement. 

  

	11.6.	The provisions of this Section 11 as to termination shall not limit or restrict the rights of any Party to seek remedies or take measures that may be otherwise available to it
at law or equity in connection with the enforcement and performance of obligations under this Agreement.

fire, flood, storm, strike or lockout, riot, war, rebellion, lack or failure of transportation facilities, court order, accident, or Acts of God, and to the extent that the foregoing are beyond a Party’s reasonable control, then, unless
conclusive evidence to the contrary is provided, upon written notice by the Party whose performance is so affected to the other, the requirements of this Agreement so affected (to the extent affected) shall be suspended during the period of, and
only to the extent of, such disability. Said Party shall be excused by reason of said force majeure only so long as it is exercising its best efforts to overcome said reason. Notwithstanding the foregoing, if a force majeure event prevents a
Party’s performance under this Agreement for an aggregate of more than [***] days, the other Party may terminate this Agreement upon written notice to the non-performing Party.

Arbitration Association (“AAA”) then in force on the date of commencement of the arbitration by three (3) arbitrators appointed in accordance with those Rules, provided that the arbitrators appointed have at least ten
(10) years arbitration experience in the pharmaceutical industry; provided however if the Parties mutually agree, such arbitration may be conducted by a single mutually agreeable arbitrator. The award rendered shall be final and binding on the
Parties. Judgment upon the award may be entered in any court having jurisdiction. The Parties agree that they will not request, and the arbitrators shall have no authority to award, punitive or exemplary damages against either Party. The costs of

discretion, to be exercised in accordance with applicable law, to allocate among the Parties the arbitrators’ fees and litigation costs, and the arbitrator(s) shall also have authority to shift any prevailing Party’s attorney’s fees

	13.7.	Waiver. No delay, waiver, omission or forbearance on the part of any Party to exercise any right, option, duty or power arising out of any breach or default by any other
Party of any of the terms, provisions or covenants hereof, will constitute a waiver by such Party of its rights to enforce any such right, option, duties or power as against the other Party hereto, or its rights as to any subsequent breach or
default by the other Party.
