2.1      Termination of Terminating Agreements. 

Effective automatically upon the Transition Period End Date, the Terminating Agreements shall terminate, except as set forth
in this Agreement. The Mutual Release Agreement, the Quality Agreement, as amended as contemplated by Section 5.3, the Pharmacovigilance Agreement, as amended as contemplated by Section 5.3, and the Common Interest Agreement shall stay in
effect in accordance with their terms. 
 2.2      Early Termination Option. 

During the Transition Period, upon forty-five (45) days prior written notice to Takeda, Orexigen may elect (i) to
terminate the Transition Period prior to the expiration of the Transition Period as provided pursuant to clause (i) or (ii) in the definition of Transition Period, or (ii) to the extent reasonably practicable in light of which Parties
are responsible for other related activities at the time, assume, prior to the end of the Transition Period, the right and responsibility to perform any remaining responsibility of, or activity or obligation performed by, Takeda pursuant to the
Collaboration Agreement or the other Existing Agreements (each a “Transitioned Activity”). The effective date of transfer of any Transitioned Activity to Orexigen will be the day immediately following the end of the forty-five
(45) day notice period or such other date agreed in writing by the Parties (the “Transitioned Activity Effective Date”). Unless agreed in writing by Takeda in its sole discretion, no such early termination or assumption will
require Takeda to incur any new obligations, to exceed the Budget or to accelerate any of the activities or obligations Takeda is performing in accordance with the Collaboration Agreement, the other Existing Agreements or this Agreement. From and
after the Transitioned Activity Effective Date for a Transitioned Activity, all of Takeda’s rights and obligations to perform such Transitioned Activity shall cease, except as expressly set forth in this Agreement, and Orexigen shall perform
such Transitioned Activity. Orexigen shall use Commercially Reasonable Efforts to perform any Transitioned Activities upon which any of Takeda’s remaining responsibilities, activities or obligations under this Agreement, the Collaboration
Agreement or the other Existing Agreements are dependent. Upon the Transitioned Activity Effective Date for any Transitioned Activity, any remaining portion of the Budget for such Transitioned Activity, whether or not such Transitioned Activity is
identified specifically in the Budget or is a component of another activity that is specifically identified in the Budget (but only as to that portion allocable to the Transitioned Activity), shall be reduced to zero and shall not be allocated to
another activity unless the Parties otherwise agree in writing.

provided in this Agreement or the Transition Services Agreement, during the Transition Period, each Party shall continue to have the rights and obligations set forth in the Collaboration Agreement and any other Existing Agreement, including, without

Plan, this Agreement, the Collaboration Agreement or any other Existing Agreement for which Takeda would incur Third Party out-of-pocket costs and expenses to the extent such performance would cause Takeda to exceed the Budget, unless the Parties
otherwise agree in writing. For the avoidance of doubt, Takeda shall have no further obligation to incur any Commercialization Costs pursuant to the Collaboration Agreement. For the avoidance of doubt, the [...***...] allocations within the
Budget and Plan represent reasonable estimates by the Parties as of the Effective Date and are subject to change based on business conditions during the Transition Period, Committee decisions made pursuant to Section 3.2.1 hereof, and the other

Confidential Information. Deliveries of such Materials will be in the form Takeda currently maintains such Materials unless otherwise mutually agreed upon by the Parties.

assign to Orexigen any and all Collaboration Patents.

Takeda’s control or to which Takeda is granted first rights regarding such activities, or final decision-making authority over Disputes regarding such activities pursuant to Section 5.7.3 of the Collaboration Agreement, and (ii) have
not been initiated by Takeda prior to the Closing Date, shall, upon Orexigen’s written request, not be initiated by Takeda, be delayed by Takeda or (subject to Section 2.2) be transitioned from Takeda to Orexigen as soon as practicable;

Orexigen will be responsible following the Transition Period, or (y) entering into any contract or agreement that would be reasonably expected to cause Orexigen to incur financial or other obligations for which Orexigen will be responsible
following the Transition Period. Unless agreed in writing by Takeda in its sole discretion, such request to not initiate, to delay or (subject to Section 2.2) to transition such activities shall not require Takeda to incur any new obligations,
financial or otherwise, or to accelerate any of the activities or obligations Takeda is performing in accordance with the Collaboration Agreement, the other Existing Agreements or this Agreement. For the avoidance of doubt, if such activities are
not initiated or are indefinitely delayed throughout the Transition Period, any remaining portion of the Budget for such activities, whether or not such activities are identified specifically in the Budget or are a component of another activity that
is specifically identified in the Budget (but only as to that portion allocable to the Transitioned Activity), shall be reduced to zero and shall not be allocated to another activity unless the Parties otherwise agree in writing. During the
Transition Period, each Party shall use good faith efforts to discuss such ongoing activities or the initiation of such activities through the JCC and JDC or working groups thereof. Notwithstanding anything to the contrary contained in this
Agreement or the Transition Services Agreement, if Orexigen requests that Takeda terminate [...***...] during the Transition Period, Takeda will terminate such [...***...] and
will have no obligation to restart such [...***...].

3.5      Other Transition Activities. 

During the Transition Period and to the extent permitted under any applicable Third Party agreements to the extent relating to

foregoing (including any analyses, projections, presentations, notes, memoranda or communications relating to any of the foregoing to or from
Third Parties) that Takeda reasonably determines to be its Confidential Information; 
 (c)    at
Orexigen’s request, Takeda shall assign to Orexigen any and all agreements to which Takeda or its Affiliate and a Third Party are parties and that govern any Development, Commercialization or Manufacturing activities conducted in connection
with Products prior to the Transition Period End Date, or if such assignment of any such Third Party agreement is not permitted under the relevant agreement and such Third Party will not consent to such assignment, or is not practicable because such
agreement also relates to Takeda activities and products outside the scope of the Collaboration, Takeda shall (i) grant to Orexigen other rights to provide to Orexigen the benefit of such non-assignable agreement, at Orexigen’s expense, to
the extent permitted under the terms of such non-assignable agreement, or (ii) to the extent such grant is not permitted under the terms of such non-assignable agreement or otherwise not reasonably practicable, the Parties shall discuss in good
faith an alternative solution to enable Orexigen to receive, at Orexigen’s expense, the benefit of the terms of such non-assignable agreement; 

(d)    for any agreements to which Takeda or its Affiliate and a Third Party are parties that includes an
Orexigen obligation under the Collaboration Agreement to reimburse Takeda for costs incurred under such agreement, Takeda will, at Orexigen’s written request within [...***...]
of the Transition Period, terminate such agreement effective no later than the last day of the Transition Period or such earlier date as Orexigen may reasonably request, subject in either case to the applicable notice provisions of such agreement in
which case termination shall be effective at the end of such notice period, and pay any associated termination fees or wind down costs associated with such termination, it being understood that Takeda will have the sole and exclusive right to
determine the manner in which any such agreement will be terminated, and that Orexigen may not request the termination of any such agreement earlier than the last day of the Transition Period if such earlier termination would cause Takeda’s
termination fees or wind down costs with respect to such agreement to be greater than if such termination were to occur on the last day of the Transition Period; and 

(e)    Takeda will provide to Orexigen such other reasonable transition assistance and support using
[...***...]. The Parties expressly acknowledge that the Transition Services Agreement (including Section 2.5 thereof) contemplates that there may be transition services that Orexigen may request Takeda perform that would otherwise not be
included in this Section 3.5(e). 
 Notwithstanding the foregoing, Takeda shall have no additional obligation hereunder
to provide Orexigen with any Materials to the extent Takeda otherwise provides Orexigen with such Materials as part of the activities or obligations Takeda is performing in accordance with the Collaboration Agreement or any other Existing Agreement.

those taxes from the payment; (b) pay the taxes to the proper taxing authority; and (c) send evidence of the obligation together with proof of payment to the other Party promptly following that payment. Takeda shall pay any and all taxes
that are due and payable by Takeda on payments made to Takeda under this Agreement.

	2.	 PERFORMANCE OF SERVICES. 



2.1        Services. Except as otherwise provided herein, for the duration of
the applicable Service Period with respect to each Service, the Provider shall perform or cause to be performed such Service for the Purchaser in a commercially reasonable manner and in accordance with applicable Law and the specifications set forth
in the applicable Services Schedule; provided that to the extent any Services to be performed hereunder (or services substantially similar to such Services) were performed by a Party immediately prior to the Closing Date, such Services shall
be provided by the Provider using Commercially Reasonable Efforts. In addition, to the extent that a Party reasonably requires the other Party to perform certain activities in order to enable such Party to perform its Services hereunder, then such
Party’s obligation to perform its applicable Services shall be conditioned on the other Party’s performance of such activities in accordance with the terms hereof. For the avoidance of doubt, to the extent that Orexigen is


  
 2 








 EXECUTION COPY 
  

obligated to perform Services under Service Schedules that list Takeda as the Provider, Orexigen shall perform all such Services at no cost to
Takeda. 
 2.2        Subcontractors. Subject to the Purchaser’s prior
written consent (which consent shall not be unreasonably withheld, delayed or conditioned), the Provider shall be permitted to subcontract to Third Parties any of its obligations under this Article 2; provided that the Purchaser may withhold
such consent where such subcontracting is reasonably expected to increase the cost of such Service to the Purchaser, as determined by reference to the rates in effect for such Service during the month preceding such request to subcontract;
provided, further, the Purchaser’s prior written consent shall not be required for any such subcontracting where the Provider: (a) has already subcontracted for such Service as of the Closing Date; or (b) seeks to enter
into a subcontract with its Affiliates (in which case the cost shall remain unchanged). No subcontract pursuant this Section 2.2 shall relieve the Provider of any of its obligations under this TSA, and the Provider shall be liable for the
actions of its subcontractor, including, for the avoidance of doubt, pursuant to Article 9. 

2.3        Requirements. Notwithstanding anything to the contrary contained
herein, the Provider shall not be required to provide, or cause to be provided, any Service in a manner that could reasonably be expected to constitute a violation of any applicable Laws. The Provider shall promptly notify the Purchaser of the
curtailment or cessation of any Service in the event that the Provider reasonably believes that providing such Service would violate any applicable Laws, and the Parties shall cooperate with each other in good faith to alter such Service (or to
contemplate an alternative service) such that the Provider can provide such Service (or alternative service) to the Purchaser in accordance with applicable Laws. 

2.4        Access. The Purchaser agrees to grant to the Provider’s
personnel access to the Purchaser’s locations, systems and information (subject to the provisions of confidentiality set forth in Article 7) as reasonably necessary for the Provider to perform its obligations hereunder; provided that
such access shall not unreasonably interfere with any of the businesses or operations of the Purchaser or its Affiliates. In connection with such access, the Provider agrees to comply with the Purchaser’s reasonable policies and to permit its
personnel to be appropriately supervised or accompanied by the Purchaser’s personnel during such access as required by the Purchaser. 

2.5        Requested Services. If a Party desires the other Party (or its
Affiliates) to perform, or cause to be performed, a service that is not included in the then-current Services Schedules (a “Requested Service”) that was provided by one Party to the other Party during the [...***...] prior to the Closing Date or during the Transition Period, such Party shall deliver a written notice to the other Party requesting the Requested Service, which notice shall include
a proposed specification for the Requested Service in the form of Exhibit C attached hereto. The Parties shall negotiate the terms and conditions of each Requested Service in good faith, provided, that the Party requested to provide such Requested
Service shall not be permitted to refuse to provide the Requested Service where the request was provided within [...***...] of the Closing Date and: (a) it is reasonably practicable for such Party (or its Affiliates) to perform such
Requested Service; or (b) such Party (or its Affiliates) has previously performed the Requested Service for itself or its Affiliates during the [...***...] prior to the Closing Date or during the Transition Period. Without limiting a
Party’s obligations under Section 2.1, it 
  

***Confidential Treatment Requested 

  
 3 








 EXECUTION COPY 
  

is expected that the price for any Requested Services would be based upon the fully burdened cost of such Party to perform such Requested
Service unless otherwise agreed in writing by the Parties. After any Requested Service has been agreed upon pursuant to this Section 2.5 and the related specification therefor has been memorialized in writing and signed by both Parties, such
writing shall constitute a Service Schedule and the Requested Service shall thereupon be deemed to be a Service hereunder; provided that a Party may refuse to provide a Requested Service if such Requested Service is (i) any activity that
Orexigen directed Takeda to not initiate, to delay or to transition to Orexigen pursuant to Section 3.1.4 of the Separation Agreement, (ii) any activity that Orexigen has assumed pursuant to the Separation Agreement, or (iii) any
Service described on a Service Schedule that has expired, lapsed, or has otherwise been terminated. Notwithstanding anything to the contrary in the Separation Agreement or this TSA, except as may be required for Takeda to complete the DDI PMR Study
and the TQT PMR Study to [...***...] in accordance with Section 3.7 of the Separation Agreement, Takeda shall not be required to perform any Development activities after
the Transition Period End Date. 
 2.6        Obligations. Without limiting a
Party’s obligations under Section 2.1, except as expressly provided in any applicable Services Schedule, in providing the Services, neither Party shall be obligated to: (a) hire any additional employees; (b) maintain the
employment of any specific employees; (c) purchase, lease or license any additional equipment or software; (d) enter into any agreements with any Third Party (including any vendor); or (e) incur costs for providing such Service that
would exceed the TSA fees set forth in the Services Schedules. 

2.7        Transition of Services. The Parties acknowledge the transitional
nature of the Services and agree to cooperate in good faith and to use reasonable and customary efforts to effectuate, during the applicable Service Periods, a smooth transition of responsibility for the Services from the Provider of each Service
hereunder to the Purchaser of such Service upon the expiration of the applicable Service Period. 
  

	3.	SALES ORDER TRANSITION. 

 Unless the Parties otherwise agree in writing, any orders for the
purchase of a Takeda Coded Product in the Field in the Territory that (i) remain unfilled as of the Transition Period End Date, or (ii) require delivery after the Transition Period End Date, shall in each case, be rejected and cancelled by
Takeda. Effective as of the Transition Period End Date, if Takeda receives any order for purchase of Contrave® in the Territory, Takeda shall refer such orders to Orexigen for acceptance or
rejection as promptly as practicable. 
  

	4.	OREXIGEN LABELER CODE. 

 Orexigen shall begin selling Contrave® under its own labeler code within [...***...] of the Closing Date, unless otherwise agreed by Takeda in writing. 
  

	5.	MAINTENANCE OF COMMERCIAL AND GOVERNMENT CONTRACTS. 

 Orexigen shall use commercially
reasonable efforts to enter into its own agreements with Customers as promptly as practicable; provided that any decision about entering in any agreement with a Customer and the terms of such agreement shall be made in Orexigen’s sole

  
 ***Confidential Treatment Requested

 EXECUTION COPY 
  

discretion. For the avoidance of doubt, with respect to those agreements between Takeda and Customers that have a term extending past the Transition Period End
Date and are not terminable with respect to the Takeda Coded Product except in the event that Orexigen enters into an agreement with such Customer on the same terms or terms more favorable to the Customer, then Orexigen shall use commercially
reasonable efforts to enter into such agreements as promptly as practicable. Orexigen shall reimburse Takeda for all Rebates that Customers claim after the Transition Period End Date, and that Takeda properly pays pursuant to the Rebate Program, on
sales of all Takeda Coded Products that occur after the Transition Period End Date. 
  

	6.	METHOD OF PAYMENT. 

 6.1      Invoices. 

6.1.1    Takeda shall submit to Orexigen a monthly invoice or invoices, within [...***...] after the end of each month beginning with the first full month after the Closing Date, for Services provided to Orexigen hereunder during such month and/or for all Rebates that
Takeda pays that are reimbursable by Orexigen pursuant to Article 5 during such month. Takeda shall submit such invoice(s) to:

6.3      Invoice; Interest. Invoice(s) for each month shall be paid in full by the
Purchaser by wire transfer of immediately available funds, each within [...***...] after the date of the respective invoice. If the Provider does not receive payment of any sum due to it on or before the due date, simple interest shall
thereafter accrue on the sum due to the Provider until the date of payment at a rate equal to the lesser of (a) [...***...] percent ([...***...]%) per month or (b) the maximum applicable legal rate, calculated on the total
number of days payment is delinquent.

6.4      Records, Audits.    Each Party shall keep, and shall cause
each of its respective Affiliates, if any, to keep, full, true, and accurate books of accounting in accordance with IFRS or GAAP, as applicable, containing all particulars that may be necessary for the purpose of calculating all amounts invoiced to
the other Party under this TSA, for a period of [...***...] after the Calendar Year in which such invoices were originally issued, and in sufficient detail to permit the other
Party to confirm the accuracy of all amounts paid hereunder. Each Party shall have the right to conduct an audit to verify the accuracy of the financial reports furnished by the other Party pursuant to Section 7.7 of the Collaboration
Agreement. 
 6.5      Tax Residence Certificate.    To the extent
required by applicable Laws, a Party (including any entity to which this TSA may be assigned) receiving a payment pursuant to this TSA shall provide the remitting Party appropriate certification from relevant governmental authorities that such Party
is a tax resident of that jurisdiction, if such receiving Party wishes to claim the benefits of an income tax treaty to which that jurisdiction is a party. Only if the certificate is required under applicable Laws, then upon the receipt thereof, any
deduction and withholding of taxes shall be made at the appropriate treaty tax rate. 

6.6      No Reductions.    Neither Party may deduct from, set off,
hold back or otherwise reduce in any manner whatsoever any amount owed to it hereunder or pursuant to any other agreement against any amount owed hereunder or pursuant to any other agreement by such Party to the other Party or any of such other
Party’s Affiliates. 
  

	7.	CONFIDENTIALITY. 

 The Parties acknowledge that this TSA and all of the respective terms of
this TSA shall be treated as Confidential Information of both Parties. The provisions of Sections 10.1, 10.2, 10.3, 10.4, 10.5 and 10.9 of Article 10 of the Collaboration Agreement are incorporated into this TSA by this reference thereto,
mutatis mutandis, with references therein to “this Agreement” or the like including references to this TSA and the Separation Agreement. For clarification, the following types of Materials received or created for the benefit of the
Purchaser or its designee during the Services Period that fall within the definition of Confidential Information shall be Confidential Information of the Purchaser, and the Purchaser shall be considered the disclosing Party and the Provider shall be
considered the receiving Party with respect to such Confidential Information: information, written materials, data (including Clinical Trial data), results, documents, reports, presentations, plans, records, accounts, or notes relating to
Development, Manufacturing or regulatory activities solely related to any Product or any filing, prosecution, maintenance and enforcement activities regarding any Collaboration Patent or Product Trademark under Sections 9.2 through 9.6 of the
Collaboration Agreement, but excluding any internal analyses, projections, presentations, notes, memoranda or communications relating to any of the foregoing (including any analyses, projections, presentations, notes, memoranda or communications
relating to any of the foregoing to or from Third Parties) that the receiving Party reasonably determines to be its Confidential Information. Takeda will have the right to use such Confidential Information of Orexigen (i) as permitted by the
Existing Agreements, the Separation Agreement and this TSA subject to the terms of Sections 10.1, 10.2, 10.3, 10.4, 10.5 and 10.9 of Article 10 of the Collaboration Agreement and Section 3.6.2 of the Separation Agreement, as
applicable, and (ii) with respect to such Confidential Information other than Clinical Trial data relating to the Products, preclinical and non-clinical data relating to the

Products, non-public information contained in the Contrave® NDA or the Contrave® IND, and unpublished Collaboration Patents, for Takeda’s internal business purposes, subject to the restrictions of this Article 7 and provided that all Confidential Information so used
shall be sufficiently anonymized such that it cannot reasonably be expected to be associated with Contrave® or Orexigen. 

 

	8.	TERM AND TERMINATION. 

 8.1      Term,
Expiration.    This TSA shall become effective as of the Closing Date and, subject to its prior termination with respect to any Service in accordance with this Article 8, shall be in effect with respect to each Service until
(and shall terminate with respect thereto upon) the expiration of the Service Period as set forth in the applicable Services Schedule and shall expire in its entirety upon the expiration of the last Services Schedule to expire; provided that
the Parties may terminate this TSA in its entirety, or with respect to any Service, by mutual written agreement at any time. 

8.2      Termination for Cause.    Either Party may terminate this
TSA by giving written notice to the other Party if such other Party has breached a material provision of this TSA in connection with such Services, or ceases to provide such Services without the prior consent of the other Party, and in each case has
failed to cure such breach within sixty (60) days after being given written notice of such breach. 

8.3      Termination for Convenience.    Except as otherwise provided
in the applicable Services Schedule, the Purchaser shall have the right at any time during the applicable Service Period to terminate its obligation to purchase or receive any individual Service (or portion thereof) upon the giving of forty-five
(45) days advance written notice to the Provider. 

8.4      Fees.    From the effective date of termination of a Service
or portion thereof, the Purchaser shall no longer be obligated to pay any fees for the terminated Service or portion thereof with respect to the period following the effective date of such termination. 

8.5      Survival.    Notwithstanding anything to the contrary,
Articles 1, 4, 5, 7, 9 and 11, and Sections 6.1, 6.2 (solely with respect to payments that have accrued prior to the effective date of the termination of a Service or portion thereof or to the termination or expiration of this TSA, as applicable,

 Orexigen and Takeda Jointly Announce Orexigen’s Acquisition of 

All Rights to CONTRAVE® in United States 

Acquisition provides Orexigen ownership of CONTRAVE in nearly all major global markets 

Takeda Moves to Strengthen Focus on Recent Launches 

San Diego, CA and Deerfield, Ill., and Osaka, Japan, [MONTH] [X], 2016 – Orexigen Therapeutics, Inc. (Nasdaq: OREX) and Takeda Pharmaceuticals
U.S.A., Inc., a wholly-owned subsidiary of Takeda Pharmaceutical Company Limited (TSE:4502) (collectively “Takeda”), today announced they have agreed to terminate the Amended and Restated Collaboration Agreement for CONTRAVE® (naltrexone HCl / bupropion HCl), the market leading national branded prescription treatment option for certain overweight and obese adults for chronic weight management. Completion of the
transaction is subject to the parties’ receipt of clearance under the Hart-Scott-Rodino Antitrust Improvement Act (“HSR Act”). 
 CONTRAVE
along with diet and exercise is an important treatment option for overweight and obese adults. Orexigen and Takeda are committed to working together to ensure a successful transition of development and commercialization efforts for CONTRAVE.
Following closing of this transaction, the parties have agreed to a 180-day transition period, during which time Takeda will continue to commercialize CONTRAVE in the United States. Orexigen believes acquiring the U.S. rights to CONTRAVE will
greatly increase long-term corporate profitability and creates multiple paths to greater value creation for its shareholders. 
 Takeda will increase its
promotional resources and support towards recent launches in the inflammatory bowel disease and major depressive disorder areas. This transaction will not change Takeda’s consolidated results forecast for fiscal year 2015. 

About CONTRAVE 
 CONTRAVE, approved by the United States
Food and Drug Administration in September 2014, is indicated for use as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial body mass index (BMI) of 30 kg/m2 or greater (obese), or 27 kg/m2 or greater (overweight) in the presence of at least one weight-related

comorbid condition (e.g., hypertension, type 2 diabetes mellitus or dyslipidemia). 

The exact neurochemical effects of CONTRAVE leading to weight loss are not fully understood. CONTRAVE has two components: naltrexone, an opioid antagonist,
and bupropion, a relatively weak inhibitor of the neuronal reuptake of dopamine and norepinephrine. Nonclinical studies suggest that naltrexone and bupropion have effects on two separate areas of the brain involved in the regulation of food intake:
the hypothalamus (appetite regulatory center) and the mesolimbic dopamine circuit (reward system). 
 Four 56-week multicenter, double-blind,
placebo-controlled Phase 3 clinical trials were conducted to evaluate the effect of CONTRAVE in conjunction with lifestyle modification in 4,536 subjects randomized to CONTRAVE or placebo. The most common adverse reactions (greater than or equal to5
percent) seen in patients taking CONTRAVE included nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea. 
 Important
Safety Information for CONTRAVE (naltrexone HCl and bupropion 
 HCl) 8 mg/90 mg extended-release tablets 

CONTRAVE can cause serious side effects of suicidal thoughts or actions. CONTRAVE contains bupropion HCl which has caused some people to have suicidal
thoughts or actions or unusual changes in behavior, whether or not they are taking medicines used to treat depression. Bupropion may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of
treatment. If you already have depression or other mental illnesses, taking bupropion may cause it to get worse, especially within the first few months of treatment. 

Stop taking CONTRAVE and call a healthcare provider right away if you, or your family member, have any of the following symptoms, especially if they are
new, worse, or worry you: thoughts about suicide or dying; attempts to commit suicide; depression; anxiety; feeling agitated or restless; panic attacks; trouble sleeping (insomnia); irritability; aggression, anger, or violence; acting on
dangerous impulses; an extreme increase in activity and talking (mania); other unusual changes in behavior or mood. 
 While taking CONTRAVE, you and
your family members should pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings, and tell your healthcare provider. 

Exhibit to Agreement 

  








 EXECUTION COPY 
  

CONTRAVE has not been studied in and is not approved for use in children under the age of 18. 

Do not take CONTRAVE if you have uncontrolled high blood pressure; have or have had seizures; use 

other medicines that contain bupropion such as WELLBUTRIN, WELLBUTRIN SR, WELLBUTRIN XL, and APLENZIN; have or have had an eating disorder called anorexia or
bulimia; are dependent on opioid pain medicines or use medicines to help stop taking opioids such as methadone or buprenorphine, or are in opiate withdrawal; drink a lot of alcohol and abruptly stop drinking; use medicines called sedatives (these
make you sleepy), benzodiazepines, or anti-seizure medicines and you stop using them suddenly, as these may increase your chance of having a seizure; have taken medicines called monoamine oxidase inhibitors (MAOIs), including linezolid, within the
last 14 days; are allergic to any of the ingredients in CONTRAVE; are pregnant or planning to become pregnant. Tell your healthcare provider right away if you become pregnant. 

Tell your healthcare provider about all of your medical conditions, especially: depression or other mental illnesses; attempted suicide; seizures; head
injury; tumor or infection of brain or spine; low blood sugar or low sodium; liver or kidney problems; high blood pressure; heart attack, heart problems, or stroke; eating disorder; drinking a lot of alcohol; prescription medicine or street drug
abuse; are 65 or older; diabetes; breastfeeding. 
 Tell your healthcare provider about all the medicines you take, including prescription and
over-the-counter medicines, vitamins, and herbal supplements. 
 Swallow CONTRAVE tablets whole. Do not cut, chew, or crush CONTRAVE tablets. Do not
take 
 CONTRAVE with high-fat meals. It may increase your risk of seizures. Take CONTRAVE exactly as prescribed. 

CONTRAVE may cause serious side effects, including: 

Seizures. There is a risk of having a seizure when you take CONTRAVE. The risk is higher in people who: take higher doses of CONTRAVE; have certain
medical conditions; take CONTRAVE with certain other medicines. Do not take any other medicines while you are taking CONTRAVE unless your healthcare provider has said it is okay. If you have a 

Exhibit to Agreement 

  








 EXECUTION COPY 
  

seizure, stop taking CONTRAVE, tell your healthcare provider right away, and do not take CONTRAVE again. 

Risk of opioid overdose. Do not take large amounts of opioids, including opioid-containing medicines, such as heroin or prescription pain pills, to try
to overcome the opioid-blocking effects of naltrexone. 
 This can lead to serious injury, coma, or death. Get emergency medical help right away if you have
trouble breathing; become drowsy with slowed breathing; have slow, shallow breathing; or feel faint, dizzy, or confused. 
 Sudden opioid withdrawal.
Do not use any type of opioid (must be opioid-free) including street drugs, prescription pain medicines (including tramadol), cough, cold, or diarrhea medicines that contain opioids, or opioid-dependence treatments, buprenorphine, or methadone,
for at least 7 to 10 days before starting CONTRAVE. This may cause you to have sudden symptoms of opioid withdrawal, which can be severe and may require hospitalization. Tell your healthcare provider you are taking CONTRAVE before a medical
procedure or surgery. 
 Severe allergic reactions. Stop taking CONTRAVE and get medical help immediately if you have any signs and symptoms of
severe allergic reactions: rash, itching, hives, fever, swollen lymph glands, painful sores in your mouth or around your eyes, swelling of your lips or tongue, chest pain, or trouble breathing. 

Increases in blood pressure or heart rate. Your healthcare provider should check your blood pressure and heart rate before and during CONTRAVE
treatment. 
 Liver damage or hepatitis. Stop taking CONTRAVE if you have any symptoms of liver problems: stomach area pain lasting more than a few
days, dark urine, yellowing of the whites of your eyes, or tiredness. Your healthcare provider may need to stop treatment if you get signs or symptoms of a serious liver problem. 

Manic episodes. CONTRAVE can cause some people who were manic or depressed in the past to become manic or depressed again.

Visual problems (angle-closure glaucoma). Signs and symptoms may include: eye pain, changes in vision, swelling or redness in or around the eye. Talk
with your doctor to find out if you are at risk. 
 Increased risk of low blood sugar (hypoglycemia) in people with type 2 diabetes mellitus who also
take medicines to treat their diabetes (such as insulin or sulfonylureas). Check your blood sugar before and during CONTRAVE treatment. 
 The most
common side effects of CONTRAVE include nausea, constipation, headache, vomiting, dizziness, trouble sleeping, dry mouth, and diarrhea. 
 These are not all
the possible side effects of CONTRAVE. Tell your healthcare provider about any side effect that bothers you or does not go away. 
 Talk to your doctor
or healthcare professional. Please see accompanying full Prescribing Information and Medication Guide for CONTRAVE. 
 You are encouraged to
report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
