BUPROPION HYDROCHLORIDE SUPPLY AGREEMENT

This Bupropion Hydrochloride Supply Agreement (this Agreement) is made as of this day of November 24, 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 CHEMI S.p.A. (CHEMI),
a corporation of Italy located at via dei Lavoratori, 54 -20092, Cinisello Balsamo (Milan).

WHEREAS, CHEMI is the manufacturer of
Bupropion Hydrochloride and is contractually responsible for Bupropion Hydrochloride and whereby CHEMI wishes to sell and manufacture Bupropion Hydrochloride to OREXIGEN on the terms described herein; and

WHEREAS, OREXIGEN desires a supply of commercial quantities of Bupropion Hydrochloride on the terms described herein.

NOW, THEREFORE, in consideration of the mutual covenants set forth herein, CHEMI 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 Bupropion Hydrochloride by OREXIGEN from CHEMI during the term of this Agreement. The premises and the Schedules and
Appendix attached hereto constitute an integrant and substantial part 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 CHEMI (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. 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 Bupropion Hydrochloride sold by CHEMI to OREXIGEN will be manufactured by CHEMI in accordance with the terms of this Agreement.
|---- | -----------------------------------------------------------------------------------------------------------------------------------



|2. | MANUFACTURING; SPECIFICATIONS
|-- | -----------------------------



|2.1. | CHEMI shall supply the Bupropion Hydrochloride 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 CHEMIs drug master file (DMF) for Bupropion Hydrochloride 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 CHEMI wishes to make any change to the Specifications (including, but not
limited to, any change that could affect the purity, potency, identity and/or physical properties of the Bupropion 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, so as to permit OREXIGEN to understand the reasons for the proposed change and evaluate the impact of such change on
its development plans, its plans to seek regulatory approval and its commercialization plans with respect to oral formulations containing Bupropion Hydrochloride (the Finished Products). OREXIGEN may request from time to time that
CHEMI implement voluntary changes to the Specifications upon written request to CHEMI. CHEMI 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, CHEMI 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, CHEMI shall not change the Specifications unless [* * *], each having jurisdiction over Bupropion
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, CHEMI shall not supply to OREXIGEN hereunder, and OREXIGEN shall have no obligation to accept, any Bupropion Hydrochloride from CHEMI manufactured in contravention of this Section 2.2.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.3. | CHEMI will take commercially reasonable steps necessary to enable OREXIGEN to secure from the relevant Regulatory Agencies approval of CHEMI as a source of supply of
Bupropion Hydrochloride for OREXIGENs Finished Products to be marketed anywhere in the world. Without limiting the generality of the foregoing, CHEMI will supply to OREXIGEN sufficient quantities of Bupropion 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 CHEMI as its
supplier of Bupropion Hydrochloride for its initial Finished Product candidate. CHEMI will be responsible for procuring and maintaining all regulatory filings and any other compliance efforts, including without limitation, the DMF, related to
Bupropion Hydrochloride that are required in order to obtain approval from the FDA of OREXIGENs NDAs (or ANDAs, if applicable) referencing Bupropion Hydrochloride and equivalent approvals from Regulatory Agencies in other jurisdictions, at no
additional cost to OREXIGEN. CHEMI has filed the DMF with the FDA and has provided 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

|3. | FORECASTS; FIRM COMMITMENT; PURCHASE ORDERS
|-- | -------------------------------------------



|3.1. | In order to assist CHEMI in planning the production runs for Bupropion Hydrochloride, beginning at least [* * *] ([* * *]) [* * *] prior
to OREXIGENs anticipated Commercial Launch (as defined in Section 3.2), OREXIGEN shall use its commercially reasonable efforts to provide to CHEMI, prior to the beginning of each calendar quarter, a twelve (12) month rolling forecast
of the quantities of Bupropion 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 three (3) months of each Rolling Forecast shall constitute a binding order on CHEMI and OREXIGEN for the quantities of Bupropion Hydrochloride specified therein (Firm Commitment), and the following [* * *]
([* * *]) months of the Rolling Forecast shall be non-binding estimates and shall be used by CHEMI for planning purposes only. CHEMI shall be obligated to supply no less than [* * *] percent ([* * *]%) of the quantity
of Bupropion Hydrochloride ordered by OREXIGEN pursuant to any Purchase Order which complies with Section 3.3. Further, CHEMI agrees to use commercially reasonable efforts to deliver any quantities of Bupropion Hydrochloride ordered by OREXIGEN
which exceed OREXIGENs Firm Commitment 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 (the date of such approval hereinafter referred to as the
QualificationDate) and have been made generally commercially available (hereinafter Commercial Launch), CHEMI shall, within [* * *] ([* * *]) business days after OREXIGEN has provided
its quarterly forecast, notify OREXIGEN in writing of any prospective problems CHEMI 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 CHEMI 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 Bupropion Hydrochloride ordered, the total Price (as defined in Section 5.2) for such quantities
of Bupropion 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 CHEMI 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, CHEMI shall acknowledge receipt
of OREXIGENs Purchase Order and confirm that the amounts of Bupropion Hydrochloride ordered in the Purchase Order will be timely supplied. For the avoidance of doubt, CHEMI shall be obligated to accept any such Purchase Order which complies
with this Section 3.3. Notwithstanding the foregoing, any failure by CHEMI to respond to a Purchase Order within such [* * *] ([* * *]) day period shall be deemed acceptance of such Purchase Order.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3.4. | CHEMI agrees to retain a safety stock of Bupropion Hydrochloride to be used for sale by OREXIGEN based on the average monthly quantities in the Rolling Forecast. CHEMI
will promptly notify OREXIGEN if CHEMIs manufacturing capacity will be insufficient to fill a Purchase Order submitted by OREXIGEN.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3.5. | During any period during this Agreement in which CHEMI, for any reason, including, without limitation, a force majeure as provided in Section 13.1, fails to
deliver the requisite quantities of Bupropion Hydrochloride included within any Firm Commitment Purchase Order, within [* * *] ([* * *]) days after the date of delivery confirmed in writing by CHEMI or if CHEMI otherwise
anticipates or notifies OREXIGEN that it will be unable to make delivery of all or a portion of the ordered Bupropion Hydrochloride within [* * *] ([* * *]) days after the confirmed date of delivery, then OREXIGEN may refuse such
late shipment of Bupropion Hydrochloride from CHEMI and purchase such quantities elsewhere. OREXIGEN shall have no further obligations to purchase the undelivered Bupropion Hydrochloride ordered from CHEMI pursuant to a Firm Commitment Purchase
Order.
