each be the account of such Party, any Affiliate thereof, or any Third Party), in such allocation between such accounts, as shall be designated by the Party owed payment from time-to-time upon written notice, unless otherwise specified in writing by
such Party, with any such designated account(s) and/or allocation(s) to remain effective with respect to payments owed to such Party until it provides written notice to the other Party setting forth any changes to such account(s) or allocation(s)
for payment (in which case any changes specified in such notice shall become effective on the date specified therein). 
 (c) In the event
that any payment due hereunder is not made when due, such payment shall accrue interest from the date due at a rate equal to the greater of (i) the Prime Rate of Interest plus *** or (ii) *** per month, or, if less, the maximum interest
rate legally permissible in the Territory, calculated based on the number of days such payments are paid after the date such payments are due. The payment of such interest shall not limit a Party from exercising any other rights it may have under
this Agreement as a consequence of the lateness of any payment.

as required in order for Purdue to comply with Applicable Law, Purdue shall keep complete and accurate records in sufficient detail to permit BDSI to confirm the completeness and accuracy of (i) the information presented in each Royalty

completeness and accuracy of the information in the Royalty Statements and amounts of payments due under this Article IV. 
 (e) All taxes
levied on account of the payments accruing to a Party under this Agreement shall be paid by such Party for its own account, including taxes levied thereon as income to such Party. If provision is made in Applicable Law for withholding, such tax
shall be deducted from the payment made by a Party (the “Paying Party”) to the other Party (the “Paid Party”) hereunder, shall be paid to the proper taxing authority by the Paying Party, and a receipt of payment of
such tax shall be secured and promptly delivered to the Paid Party. Each Party agrees to reasonably assist the other Party, as reasonably requested thereby and at the Paid Party’s expense, in claiming exemption from such deductions or
withholdings under any double taxation or similar agreement or treaty from time to time in force or in otherwise seeking the return, refund, or credit of any such withheld amount as applicable.

 ARTICLE VII 

PATENTS AND TRADEMARKS 

Section 7.01 Maintenance of Licensed Patents and Licensed Marks. BDSI shall control and, except as explicitly set forth in
this Article VII, have full discretion in the preparation, filing, prosecution, maintenance, and defense of the Licensed Patents and Licensed Marks in the Territory, including any ex parte reexamination proceedings, inter partes review
proceeding, post grant review proceeding, derivation proceeding, action for declaratory judgment, interference proceeding or other attack upon the validity, title or enforceability of any Licensed Patents in the Territory. Upon written request by
BDSI, Purdue shall provide such assistance as may be necessary to enable BDSI to prosecute and obtain new patents related to any Licensed Improvements or Product Improvements Controlled by BDSI, with the cost and expense of such assistance, other
than with respect to Joint Improvements, to be borne by BDSI. BDSI shall keep Purdue advised by forwarding to Purdue copies of all official correspondence (including, but not limited to, applications, office actions, responses, etc.) relating to the
prosecution and maintenance of the Licensed Patents, and shall provide Purdue an opportunity to comment on any proposed responses, voluntary amendments, submissions, or other actions of any kind to be made with respect to Licensed Patents. In the
event that BDSI desires to abandon any Licensed Patents and/or Licensed Marks in the Territory, BDSI shall provide reasonable prior written notice to Purdue of its intention to abandon and a reasonable opportunity to discuss BDSI’s rationale
supporting such abandonment. In the event that BDSI decides to abandon any Licensed Patent in the Territory that contains Valid Claims that are specific to buprenorphine and Cover any Licensed Product, but does not contain any Valid Claims that
Cover any BEMA-based products incorporating any API other than buprenorphine (such a Licensed Patent, a “Buprenorphine-Specific Patent”), (a) BDSI shall provide prompt written notice of such decision to Purdue and
(b) Purdue may elect by written notice to BDSI, given within *** business days of the aforementioned notice from BDSI, continue the maintenance, defense or prosecution of such Buprenorphine-Specific Patent at Purdue’s expense, and Purdue
shall be entitled to undertake such maintenance, defense, or prosecution if BDSI does not, within *** business following such written election by Purdue, notify Purdue in writing that BDSI will instead continue the maintenance, defense or
prosecution of such Buprenorphine-Specific Patent. If BDSI does provide a subsequent notice to Purdue electing to retain control of such maintenance, defense or prosecution of a particular Licensed Patent, BDSI shall retain such control until such
time as it later again elects to abandon such Buprenorphine-Specific Patent, in which case the rights and obligations of the Parties with respect thereto hereunder shall again apply. In the event Purdue does actually assume maintenance, defense, and
prosecution of a Buprenorphine-Specific Patent pursuant to the foregoing, the ownership of such Buprenorphine-Specific Patent shall be retained by BDSI. 

Section 7.02 Filing, Prosecution, and Maintenance of Patents Covering Purdue Improvements. Purdue shall control and, except
as explicitly set forth in this Section 7.02, have full discretion in the preparation, filing, prosecution, maintenance, and defense of any Patents owned or controlled by Purdue or any Affiliate thereof Covering any Purdue Improvement,
including any ex parte reexamination proceedings, inter partes review proceeding, post grant

review proceeding, derivation proceeding, action for declaratory judgment, interference proceeding or other attack upon the validity, title or enforceability of any such Patents in the Territory.
Purdue shall keep BDSI advised with respect to the foregoing by forwarding to BDSI copies of all official correspondence (including, but not limited to, applications, office actions, responses, etc.) relating to the prosecution and maintenance of
such Patents, and shall provide BDSI a reasonable advance opportunity (to be no less than *** business days) to review and comment on any proposed patent applications, responses, voluntary amendments, submissions, or other actions of any kind to be
made with respect to any such Patents, and Purdue shall reasonably take into consideration any reasonable comments made by BDSI with respect thereto. In the event that Purdue desires to abandon any such Patents Covering any Purdue Improvement,
Purdue shall provide reasonable prior written notice to BDSI of Purdue’s intention to abandon and a reasonable opportunity to discuss Purdue’s rationale supporting such abandonment. 

Section 7.03 Prosecution of Infringement. During the Term, each Party shall give prompt written notice to the other Party
of any Third Party act in the Territory that (a) concerns any product(s) that contain buprenorphine as the sole API and (b) may infringe the Licensed Patents and/or the Licensed Marks in the Territory. BDSI shall, as between the Parties,
have the sole and exclusive right with respect to Licensed Marks and Licensed Patents, but not, in either case, the obligation, to bring and control any action or proceeding (i) concerning any potential or actual infringement of the Licensed
Patents or Licensed Marks or (ii) concerning any potential or actual misappropriation of any Licensed Know-How. If BDSI is unable to initiate or to prosecute such action solely in its own name or it is otherwise Commercially Reasonable and
reasonably advisable to obtain an effective or interim remedy, Purdue shall, if and as requested by BDSI and at BDSI’s sole expense (which shall be reasonable and documented), join such action and take such other reasonable steps requested by
BDSI as are necessary for BDSI to initiate litigation to prosecute and maintain such action, provided, that, under no circumstances will Purdue be obligated to, amend or alter any of the terms of this Agreement in a manner adverse to Purdue’s
interests in order to enable BDSI to initiate litigation to prosecute and maintain such action. Purdue shall provide, at BDSI’s sole expense (which shall be reasonable and documented), such other assistance and cooperation to BDSI as may be
necessary to prosecute any action against such Third Party. Any damages, monetary awards, or other amounts recovered or received in settlement by BDSI shall be applied proportionately first to defray the unreimbursed reasonable, documented costs and
expenses (including reasonable attorneys’ fees) incurred by Purdue and BDSI in the action, with the remaining balance thereof (A) to be retained by BDSI if and to the extent that the amounts recovered or received by BDSI pertain to
Licensed Patents other than any Buprenorphine-Specific Patents or that pertain to Buprenorphine-Specific Patents but are recovered or received with respect to the manufacture, use, sale, or import of a product other than a Licensed Product or
(B) to be split *** to Purdue and *** to BDSI if and to the extent that the amounts recovered or received by BDSI directly pertain to any Buprenorphine-Specific Patents and the manufacture, use, sale, or import of a Licensed Product. 

Section 7.04 Infringement Claimed by Third Parties. In the event a Third Party commences a judicial or administrative
proceeding against a Party and such proceeding, other than a proceeding to which Section 7.01 applies, pertains to the manufacture, use, sale,

marketing, or import of a Licensed Product in the Territory by or on behalf of Purdue, an Affiliate thereof, or a Sublicensee (the “Third Party Claim”), or threatens to commence
such a Third Party Claim, the Party against whom such proceeding is threatened or commenced shall give prompt notice to the other Party and the Parties shall reasonably consult with each other with respect to possible strategies for addressing the
alleged infringement. 
 Section 7.05 Payment of Costs and Expenses. Upon its receipt of a reasonably detailed invoice
setting forth a Party’s reasonable, documented costs and expenses incurred pursuant to any provision of this Article VII relating to the Territory, for which the other Party shall be liable in accordance with this Article VII, such other Party
shall pay such costs and expenses within *** of receipt of an invoice therefor. 
 ARTICLE VIII

of any contractual obligation of confidentiality between such Party and any Third Party, in which case the Party making such disclosure shall instead use Commercially Reasonable Efforts to minimize the amount of the other Party’s Confidential
Information to be disclosed, or delay the disclosure of the other Party’s Confidential Information, to the extent reasonably possible without, as determined in good faith by the Party making such disclosure, adversely affecting the
negotiations, transaction (or terms thereof), or existing relationship in connection with which such disclosure is being made.

arising out of the indemnified matter as soon as reasonably practicable, and in any event no later than within *** after the indemnified Party has actual Knowledge of such Claim or Loss,
provided, however, that, if the Party entitled to indemnification fails to promptly notify the indemnifying Party pursuant to this subsection (a), the indemnifying Party will only be relieved of its indemnification obligation under this Article X to

BDSI’s, its Affiliates’, or any of their respective Third Party licensees’ or Third Party sublicensees’ ability to manufacture, develop, or commercialize Licensed Products or any other BEMA-based Products anywhere in the world,

regards to such Party’s Books and Records solely as expressly set forth in Section 14.11.

Demonstration Samples or any failure to comply with Applicable Laws concerning the handling of any narcotics, including buprenorphine, by or on behalf of BDSI, any of its Affiliates or any Third Party on its or their behalf or for its or their

 Section 11.06 Further Actions. Upon the terms and subject to the
conditions hereof, each of the Parties shall use its Commercially Reasonable Efforts to (a) take, or cause to be taken, all appropriate action and do, or cause to be done, all things necessary, proper or advisable under Applicable Law or
otherwise to consummate and make effective the transactions contemplated by this Agreement, (b) obtain from Competent Authorities any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained or made by
the Parties in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions contemplated by this Agreement, and (c) make all necessary filings, and thereafter make any other required

applicable securities laws and (ii) any other Applicable Law. The Parties shall cooperate with each other in connection with the making of all such filings, including by providing copies of all such documents to the other Party’s counsel
(subject to appropriate confidentiality restrictions) prior to filing and, if requested, by accepting all reasonable additions, deletions or changes suggested in connection therewith. 

Section 11.07 Equitable Relief. The Parties understand and agree that because of the difficulty of measuring economic
losses to the non-breaching Party as a result of a breach of the covenants set forth in Article VIII or in this Article XI, and because of the immediate and irreparable damage that may be caused to the non-breaching Party for which monetary damages
may not be a sufficient remedy, the Parties agree that the non-breaching Party may be entitled to seek specific performance, temporary and permanent injunctive relief, and such other equitable remedies to which it may then be entitled against the
breaching Party. This Section 11.07 shall not limit any other legal or equitable remedies that the non-breaching Party may have against the breaching Party for violation of the covenants set forth in Article VIII or in this Article XI. The
Parties agree that the non-breaching Party shall have the right to seek relief for any violation or threatened violation of Article VIII or this Article XI by the breaching Party from any court of competent jurisdiction in any jurisdiction
authorized to grant the relief necessary to prohibit the violation or threatened violation of Article VIII or this Article XI. This Section 11.07 shall apply with equal force to the breaching Party’s Affiliates. 

Section 11.08 Competing Products. During the Term, ***, neither BDSI (or any Affiliate thereof) nor Purdue (or Affiliate
thereof) shall, directly or indirectly (including by way of acquisition or in license from a Third Party, but excluding by way of out license to a Third Party by an Affiliate of Purdue), register or apply for Governmental Approval, sell, offer for
sale, commercially distribute, or otherwise commercialize (defined in manner similar to that of Commercialize, but with respect to products other than Licensed Products) any BDSI Competing Product in the Territory, and each Party shall ensure that
its Affiliates comply with the foregoing obligations, subject to the remaining portions of this Section 11.08. Each Party shall ensure that its Affiliates comply with the foregoing obligations. Notwithstanding the preceding sentence,

*** rights to (a) develop, manufacture, have manufactured, or use, in the Territory any products *** which are intended solely for commercial sale to Third Parties located outside the
Territory, (b) develop, manufacture, have manufactured, use, sell, or offer for sale in the Territory any products *** or (c) otherwise exercise BDSI’s reserved rights under Section 3.02(a) or rights granted under
Section 3.06 shall not be limited in any manner by this Agreement. Notwithstanding anything to the contrary in this Section 11.08, ***. 

Section 11.09 Right of First Negotiation. 

(a) If BDSI determines that it will (i) seek to grant any license to a Third Party that includes the right to market or promote an ROFN
Product in the Territory or (ii) develop (for purposes of obtaining Marketing Authorization thereof in the Territory), sell, market, distribute, or otherwise commercialize any ROFN Product in the Territory (itself or via any Affiliate or Third
Party) pursuant to Marketing Authorization thereof in the Territory, then BDSI shall promptly notify Purdue thereof in writing (the “ROFN Notice”). Purdue shall have [thirty (30)] days from the date it receives such ROFN Notice (the
“ROFN Notice Period”) to notify BDSI in writing of Purdue’s desire to negotiate an agreement under which Purdue (or an Affiliate thereof) would be granted rights to develop and/or commercialize such ROFN Product in the
Territory (a “Negotiation Notice”). ***. If Purdue does not provide BDSI with a Negotiation Notice within the ROFN Notice Period, or affirmatively notifies BDSI during such ROFN Notice Period that it will not pursue an agreement
with BDSI with respect to such ROFN Product in the Territory, then Section 11.08 will not apply to, and shall terminate with respect to, such ROFN Product in the Territory. 

(b) If Purdue delivers a timely Negotiation Notice, the Parties shall enter into a *** negotiation period *** (the “Negotiation
Period”), during which time the Parties shall negotiate *** with each other in good faith concerning a license to Purdue with respect to the development and/or commercialization of the applicable ROFN Product in the Territory. Not less than
*** prior to the end of the Negotiation Period, BDSI shall forward its last term sheet proposal to Purdue ***. 
 (c) In the event Purdue
provides a Negotiation Notice as provided above, BDSI will promptly provide Purdue all material information and data in the possession and Control of BDSI that is directly related to the applicable ROFN Product, or its development and/or
commercialization, in the Territory, that would be reasonably pertinent to either an understanding of, or the subject of, the license, as reasonably requested by Purdue as part of Purdue’s due diligence with respect to such license. 

(d) If BDSI and Purdue do not mutually execute a definitive agreement with respect to a license during the Negotiation Period *** or Purdue
declines in writing to enter into a license for the applicable ROFN Product, then Section 11.08 will not apply to, and shall terminate with respect to, such ROFN Product in the Territory. 

Section 11.10 Right of First Refusal. Prior to BDSI entering into any license granting rights to any Third Party under any
Patents owned or otherwise controlled by BDSI Covering an ROFR Product (“ROFR Patents”) to market and sell such ROFR Product in the Territory (a 

  
 40 









 Confidential Treatment Requested by BioDelivery Sciences International, Inc. 

Confidential treatment requested with respect to certain portions hereof denoted with 

“***” 
  

 
“Third Party License”), BDSI must notify Purdue in writing of the material terms of such Third Party License that were acceptable to BDSI and such Third Party (the “Third
Party Offer”). Purdue will have *** from the date of such notice to elect in its sole discretion to enter into an agreement with BDSI granting Purdue rights under such ROFR Patents to market and sell such ROFR Product in the Territory on
the terms of the Third Party Offer and otherwise on commercially reasonable terms and conditions (“ROFR Product License Agreement”). 

If Purdue so elects to enter into an ROFR Product License Agreement with BDSI, BDSI will immediately cease all material discussions with any
Third Party regarding any license to market and sell the applicable ROFR Product(s) under the ROFR Patents in the Territory and the Parties shall use Commercially Reasonable Efforts in good faith to negotiate and execute an ROFR Product License
Agreement with each other. If (i) Purdue does not, within such *** period, elect in writing to enter into an ROFR Product License Agreement for such ROFR Product(s) or (ii) Purdue does make such an election but, despite BDSI’s
Commercially Reasonable Efforts in good faith to negotiate and execute a ROFR Product License Agreement with Purdue, the Parties do not execute such an agreement within *** such election by Purdue, BDSI may pursue or resume discussions with any
Third Party regarding the applicable Third Party License and enter into an agreement including such Third Party License with such Third Party. Upon execution of such an agreement with a Third Party, Purdue, or any Affiliate thereof with respect to
any particular Third Party Offer’s terms for any particular ROFR Product(s) pursuant to this Section 11.10, the Parties’ rights and obligations under this Section 11.10 shall terminate and Section 11.08 will not apply to,
and shall terminate with respect to, all ROFR Products in the Territory, provided that the material terms of such Third Party License shall not be materially more favorable to such Third Party than those last proposed to Purdue by BDSI. In the
event such material terms of such Third Party License are to be more favorable to such Third Party than those last proposed to Purdue by BDSI, then BDSI shall restart the process described in this Section 11.10. 

*** 
 Section 11.11
No Encumbrances. Except to the extent Purdue may assign this Agreement under Section 14.01, Purdue shall not, without the prior written consent of BDSI, such consent not to be unreasonably withheld, sell, license or sublicense
(except as permitted by Section 3.02(a)), encumber or otherwise transfer to a Third Party any of Purdue’s rights in Governmental Approvals, Marketing Authorizations, or Regulatory Filings in respect to any Licensed Product. 

Section 11.12 Cross-Border Protections. It is understood that Purdue receives no rights with respect to any Licensed
Product or Licensed Technology or otherwise by virtue of this Agreement in any countries or territories other than the Territory. For greater certainty, but without limiting the generality of anything otherwise contained in this Agreement, it is
expressly understood and agreed that Purdue shall:

Licensed Products to its and their Affiliates, Sublicensees, distributors, and customers, and shall cause its Affiliates, Sublicensees, and distributors to maintain complete and accurate written records in respect of shipments of Licensed Products
to customers, for a minimum of *** following the end of the Calendar Year to which they pertain, which records other than distributors’ records may be subject to audit and inspection by BDSI pursuant to Section 14.11 once per Calendar
Year, provided that Purdue shall, upon BDSI’s request, promptly audit such records of any of its distributors pursuant to the terms of the applicable agreement(s) therewith and share the results of such audit with BDSI.

 PRODUCT
RECALL 
 Section 12.01 Product Recall Determination. If at any time or from time to time, a Competent Authority
requests or requires Purdue to conduct a Product Recall of any Licensed Product Commercialized or otherwise distributed by or for Purdue, any Affiliate thereof, or any Sublicensee in the Territory or if a voluntary Product Recall of any such
Licensed Product in the Territory is contemplated by Purdue, any Affiliate thereof, or any Sublicensee, Purdue shall immediately notify BDSI in writing of the same. BDSI will notify Purdue of any voluntary or mandatory product recall of which BDSI
becomes aware in respect of the Licensed Product in any jurisdiction other than the Territory. 
 Section 12.02 Product Recall
Management. Purdue shall have the right to control and/or conduct any Product Recall of any Licensed Product Commercialized or otherwise distributed by or for Purdue, any Affiliate thereof, or any Sublicensee in the Territory, subject to

any designee thereof immediately upon request. BDSI shall cooperate, at, except as otherwise set forth in the Supply Agreement, Purdue’s expense, in the conduct of any Product Recall for such Licensed Product in the Territory as reasonably
requested by Purdue. In the event Purdue notifies BDSI, or BDSI otherwise becomes aware, that Purdue, any Affiliate thereof, or any Sublicensee does not intend to undertake a Product Recall (i) in respect of any death or life-threatening
Adverse Event associated with any Licensed Product or (ii) to comply with any Applicable Law with respect to any Licensed Product within, in either case, a reasonable period of time, or is unreasonably delayed in undertaking any such Product
Recall, BDSI shall be entitled to do so without Purdue’s prior written consent, in which case Purdue shall cooperate (and cause its Affiliates and Sublicensees to cooperate) in the conduct of any such Product Recall as reasonably requested by
BDSI. 
 Section 12.03 Product Recall Costs. Purdue shall, except to the extent set forth in the Supply Agreement, bear
all costs and expenses related to the conduct of any Product Recall of any Licensed Product Commercialized or otherwise distributed by or for Purdue, its Affiliates or Sublicensees in the Territory.

any such effect is attributable to the Licensed Products. Purdue shall be responsible for reporting relevant side effects to the appropriate Competent Authorities in the Territory in accordance with Applicable Laws. Each Party shall promptly inform
the other Party by telephone and in writing in the event any circumstances occur which may reasonably precipitate a possible or actual recall of any Licensed Products. Throughout the duration of this Agreement and with respect to all Licensed
Products, the Parties shall immediately notify each other of any information a Party receives regarding any threatened or pending action, inspection or communication by or from a concerned Governmental Authority which may affect the safety or
efficacy claims of the Licensed Products or the continued marketing of the Licensed Products.

 Section 13.03 Termination by BDSI. Subject to Section 13.07, BDSI
may, by written notice to Purdue, terminate this Agreement: 
 (a) upon the failure by Purdue to pay the license fee pursuant to
Section 3.01 within the time period set forth therein;

“notice” for purposes of this paragraph), provided that any failure to pay resulting from any Third Party delays with respect to the transfer of funds from Purdue to BDSI that are out of the reasonable control of Purdue and its Affiliates
(such as bank transfer delays) shall not constitute a “failure to pay” for purposes of this clause (b); or 
 (c) in the event the
First Commercial Sale of a Licensed Product hereunder does not occur by the date nine (9) months from Marketing Authorization Transfer, provided that, to the extent that Purdue can reasonably demonstrate that manufacturing or supply delays

manufacturing or supply delays. 
 Section 13.04 Discretionary Termination by Purdue.

to terminate this Agreement on *** notice given by Purdue up to *** after the consummation of such Adverse BDSI Acquisition. 

Section 13.05 Remedies. All of a non-breaching Party’s remedies with respect to a breach of this Agreement shall be
cumulative, and the exercise of one remedy under this Agreement by the non-breaching Party shall not be deemed to be an election of remedies. These remedies shall include the non-breaching Party’s right to sue for damages for such breach
without terminating this Agreement and to seek such other remedies as may be available to such Party at law or in equity.

Documentation, Product-Related Materials, Regulatory Filings, Marketing Authorizations, and Governmental Approvals, including but not limited to any market research and competitive reports, marketing reports, and related data concerning Licensed
Products or the Commercialization thereof in the Territory, and, if and as subsequently requested by BDSI in writing, (B) transfer and assign to BDSI all right, title, and interest in all Regulatory Filings, Marketing Authorizations, DINs, and
Governmental Approvals, and Product-Related Materials (other than Purdue’s right, title or interest in or to any Purdue Know-How, Purdue Patents, Purdue Marks or any other Purdue intellectual property rights embodied in any of the foregoing),
and Purdue will take, without delay, the steps required to effect re-assignment of the DINs to BDSI or a designee thereof, including by communicating the change in ownership to the relevant Competent Authority, (iii) Purdue shall, to the extent
requested by BDSI, sell and deliver the inventory of Licensed Products and work-in-process to BDSI, and BDSI shall, within *** of such delivery, pay Purdue an amount to be negotiated and agreed upon by the Parties that shall not exceed Purdue’s
reasonable, documented, direct cost of procuring such inventory or work-in-process, provided that, if BDSI exercises such right, BDSI will, if requested by Purdue and agreed to in writing by BDSI, assume Purdue’s obligations to Third Parties in
the Territory with respect to the sale or distribution of such Licensed Product, subject to, and as shall be further detailed in, any such agreement between the Parties, (iv) Purdue hereby grants BDSI and its Affiliates the perpetual,
irrevocable, royalty-free, fully-paid, exclusive right and license, transferable with this Agreement under Section 14.01 and with rights of sublicense, under the Purdue Know-How and Purdue Patents, and a perpetual, irrevocable, royalty-free,

all marketing, promotional and similar materials related solely to the Licensed Product that are in Purdue’s, its Affiliates’, or its Sublicensees’ Control, and (v) Purdue shall provide BDSI all information requested by BDSI
concerning any manufacturing, supplier, distributor, research, development, clinical study, or other contracts concerning the Development, manufacture, or Commercialization of Licensed Products or Demonstration Samples entered into by Purdue or its
Affiliates with Third Parties (“Product-Related Contracts”) and information related to any of the foregoing to the extent permitted by the terms thereof (and, if not so permitted, Purdue shall use reasonable efforts to obtain such
permission and thereafter disclose to the extent enabled by such permissions) and, if and as subsequently requested by BDSI, (X) assign such Product-Related Contracts to BDSI (to the extent assignable in accordance with their terms or consent

agreements, in order to enable such assignment as contemplated by clause (X), or (Z) otherwise reasonably facilitate BDSI’s establishment of similar relationships with such Third
Parties. BDSI shall reimburse all of Purdue’s and its Affiliates’ reasonable, documented out-of-pocket costs in performing its obligations under clause (ii)(B) (except in the case of a termination of this Agreement by BDSI pursuant to
Section 13.02 or 13.03 or by Purdue under Section 2.01(d), 6.04, or 13.04, in which case BDSI shall not have any such obligation) and clause (iv) above, provided that, in the case of clause (iv), (A) such costs shall only include
reasonable, documented royalties or other licensing fees paid by Purdue and its Affiliates to Third Party licensors as a direct and sole result of BDSI’s exercise of rights or sale of Licensed Product in the Territory under any applicable
license to Purdue from a Third Party and (B) BDSI has been provided full and complete information regarding such costs in advance with a reasonable opportunity to decline to be granted or terminate such a sublicense. 

(b) Upon any expiration of this Agreement or termination of this Agreement other than by BDSI pursuant to Section 13.02 or 13.03, or as
permitted in writing by BDSI in the event of any termination by BDSI pursuant to Section 13.02 or 13.03, Purdue (and/or its Affiliates and Sublicensees, if and as applicable) shall have the right, for a period of twelve (12) months from
the date of termination to distribute and sell existing inventory of Licensed Products subject to the terms of this Agreement (including Article IV hereof and the payment of royalties thereunder) to the extent such inventory is not purchased by BDSI
pursuant to Section 13.06(a)). 
 (c) Except as otherwise provided in this Agreement, expiration or termination of this Agreement shall
not relieve the Parties of any obligation accruing prior to such expiration or termination. Except as set forth below or elsewhere in this Agreement, the obligations and rights of the Parties under Articles I and IV and Sections 3.02(c), 3.05, 3.06,
8.01, 8.02, 8.03, 9.12, 10.01, 10.02, 10.03. 10.04 (to the extent set forth therein), 10.05, 11.01, 11.03, 11.07, 11.11, 12.01, 12.02, 12.03, 13.05, 13.06, 13.08, 14.01, 14.02, 14.03, 14.04, 14.05, 14.06, 14.07, 14.08, 14.09, 14.10, 14.11, 14.12,
14.13, and 14.14 shall survive expiration or termination of this Agreement. 
 (d) Subject to the provisions of this Section 13.06, and
except as necessary to enable the exercise of any rights granted under this Agreement or perform any obligations under this Agreement following its expiration or termination, within *** following the expiration or termination of this Agreement, each
Party shall return to the other Party, or destroy, upon the written request of the other Party, any and all Confidential Information of the other Party in its possession and upon a Party’s request, such destruction (or delivery) shall be
confirmed in writing to such Party by a responsible officer of the other Party. 
 Section 13.07 Suspension of Cure Period
Pending Dispute Resolution. If a Party gives notice of breach under Section 13.02 or Section 13.03 and the other Party, acting in good faith, disputes in writing prior to the end of the applicable cure period whether such
notice was proper, then the issue of whether a material breach has occurred shall be resolved in accordance with Section 14.03. If as a result of such dispute resolution process it is determined that the notice of breach was proper, then such
notice shall be deemed to have been effective if the breaching Party fails thereafter to cure such breach in accordance with the determination made in the resolution

process within the applicable cure period following such determination. If as a result of such dispute resolution process it is determined that the notice of breach was improper, then no such
notice shall be deemed to have been effective and this Agreement shall remain in effect. All of the terms and conditions of this Agreement, including all of the licenses granted hereunder, shall remain in full force and effect during the pendency of
such dispute resolution process. 
 Section 13.08 Bankruptcy of BDSI. The rights granted to Purdue and BDSI in Article
III and Section 13.06 are intended by the Parties to be grants of a right to “intellectual property,” as defined under Section 101(35A) of the U.S. Bankruptcy Code. The Parties intend for the protections of section 365(n) of the
U.S. Bankruptcy Code (and any corresponding or similar protections under similar laws in the Territory) to apply to such licenses granted herein and nothing in the this Agreement limits a Party’s rights with respect thereto under section 365(n)
of the U.S. Bankruptcy Code or such similar laws in the Territory; and if a Party’s obligations under the license are terminated in bankruptcy, such Party shall receive a copy of all applicable intellectual property (and embodiments thereof).

 ARTICLE XIV 

MISCELLANEOUS 

Section 14.01 Assignment. Except as explicitly contemplated by this Agreement, neither this Agreement nor any rights or
obligations hereunder may be assigned or otherwise transferred by either Party without the prior written consent of the other Party (which consent shall not be unreasonably withheld); provided, however, that, notwithstanding anything to the
contrary, either Party may assign this Agreement and its rights and obligations hereunder without the other Party’s consent (a) to any of the assigning Party’s Affiliates, including pursuant to a reorganization of such Party’s
organizational structure solely for tax purposes, (b) in connection with the transfer, sale, or other disposition of all or substantially all of the assets or business of such assigning Party (or that portion thereof, or any portion of any
product, to which this Agreement relates) to a Third Party, whether by merger, sale of stock, sale of assets or otherwise, or (c) for the benefit of a creditor or, in the event of any exercise of any remedies by a creditor, to a purchaser in a
foreclosure sale of collateral (subject to assumption by such purchaser of all obligations under this Agreement). Notwithstanding the foregoing, any such assignment to an Affiliate shall not relieve the assigning Party of its responsibilities for
performance of its obligations under this Agreement, so long as such Affiliate remains an Affiliate of the assigning Party. Each Party shall promptly notify the other Party of any purported assignment of this Agreement. The rights and obligations of
the Parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the Parties. Any purported assignment not in accordance with this Agreement shall be void. 

Section 14.02 Force Majeure. Neither Party shall be held liable or responsible to the other Party nor be deemed to have
defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement to the extent such failure or delay is caused directly by or results directly from causes beyond the reasonable control of the
affected Party, including, but not limited to, fire, floods, embargoes, terrorism, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor


  
 47 









 Confidential Treatment Requested by BioDelivery Sciences International, Inc.

disturbances, acts of God or acts, omissions, delays, or actions by any Governmental Authority or for any other reason which is completely beyond the reasonable control of the Party (other than
by reason of such Party failing to comply with Applicable Law) (collectively a “Force Majeure”). The Party prevented from carrying out its obligations hereunder shall give written notice to the other Party of an event of Force
Majeure upon it being reasonably foreseen with reasonable certainty by, or becoming known to, the affected Party, such notice to describe the cause and estimated effect of the event of Force Majeure. If and to the extent that a Party is delayed or
prevented from performing its obligation under this Agreement, other than a payment of monetary obligations, due to a Force Majeure, such Party shall nonetheless use its Commercially Reasonable Efforts to mitigate, avoid or end such delay or failure
in performance to the extent and as soon as reasonably practicable. 
 Section 14.03 Governing Law; Jurisdiction; Dispute
Resolution. 
 (a) This Agreement shall be governed by and construed under the state laws of the State of New York, without
reference to its conflicts of laws principles. 
 (b) In the event that any controversy or claim shall arise between the Parties under, out
of, in connection with, or relating to this Agreement or the breach thereof, the Party initiating such controversy or making such claim shall provide to the other Party written notice containing a brief and concise statement of the initiating
Party’s claims, together with relevant facts supporting them. During a period of ***, or such longer period as may be mutually agreed upon in writing by the Parties, following the date of said notice, the Parties shall make good faith efforts
to settle the dispute. Such efforts may include, but shall not be limited to, full presentation of both Parties’ claims and responses, with or without the assistance of counsel, before the chief executive officers (or their designees) of the
Parties. If for whatever reason the Parties are unable to resolve the dispute within *** after the issuance of a notice of dispute, then either Party may, by written notice to the other Party, submit the dispute to binding arbitration in accordance
with the provisions of Section 14.03(c). 
 (c) In the event that the Parties have been unable to reach accord using the procedures set
forth in Section 14.03(b), either Party may seek final resolution of the matter through binding arbitration upon written notice to the other Party. The failure of a Party to comply with the provisions of Section 14.03(b) with respect to
any controversy or claim shall, except as set forth in Section 14.03(d), constitute an absolute bar to the institution of any proceedings, by arbitration or otherwise, by such Party with respect to such controversy or claim. Any such
arbitration shall be held in a location that is mutually agreed upon by the Parties, which provides neither party an advantage (or, if the Parties are unable to agree on a location within *** of the initiation of arbitration hereunder, such location
shall be New York, New York), in the English language before a single independent, neutral arbitrator, who shall be selected by agreement of the Parties, or, if the Parties cannot agree within *** after commencement of arbitration, then by the
American Arbitration Association (“AAA”) in accordance with the then existing Commercial Arbitration Rules of the AAA (the “Rules”) and judgment upon the award rendered by the arbitrator may be entered or enforced
in any court having jurisdiction thereof. The arbitrator shall have at least *** experience in pharmaceutical patent licensing. The arbitrator shall permit the Parties to have discovery to the extent permitted by the Rules. The


  
 48 









 Confidential Treatment Requested by BioDelivery Sciences International, Inc. 

Confidential treatment requested with respect to certain portions hereof denoted with 

“***” 
  

 
decision of the arbitrator shall be final and binding on the Parties and shall be accompanied by a written opinion of the arbitrator explaining the arbitrator’s rationale for its decision.
Except as may otherwise be determined by the arbitrator in its award to be just and appropriate in light of the particular circumstances and outcome of the arbitration, the Party losing the arbitration shall pay all fees and costs of the arbitrator
and the AAA and reimburse the prevailing Party for its reasonable attorneys’ fees, costs, expenses, and disbursements (including, for example, expert witness fees and expenses, photocopy charges and travel expenses). The intent of the Parties
is that, except for the entering of an arbitration order in a court of competent jurisdiction or as set forth in Section 14.03(d), disputes shall be resolved finally in arbitration as provided above, without appeal, and without recourse to
litigation in the courts. 
 (d) Notwithstanding the foregoing provisions of this Section 14.03, (i) each Party shall be entitled
to seek injunctive or equitable relief to enforce the respective covenants and agreements of the Parties in this Agreement and (ii) either Party may initiate an action before any court having competent jurisdiction in order to obtain interim or
conservatory relief, such as an order to preserve the status quo and to avoid incurring irreparable harm pending the resolution of any dispute that is submitted to arbitration, to prevent or enjoin, without in either case complying with the
procedures set forth in Section 14.03(b) or 14.03(c). 
 Section 14.04 Waiver. No waiver of any term or condition of
this Agreement shall be effective unless set forth in a written instrument duly executed by or on behalf of the waiving Party. Except as specifically provided for herein, the waiver from time to time by either of the Parties of any of their rights
or their failure to exercise any remedy shall not operate or be construed as a continuing waiver of same or of any other of such Party’s rights or remedies provided in this Agreement. 

Section 14.05 Severability. In case any provision of this Agreement shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. Any provision of this Agreement held invalid or unenforceable in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable. 
 Section 14.06 Notices. All notices and other communications provided for
herein shall be dated and in writing and shall be deemed to have been duly given (a) on the date of delivery, if delivered personally, by e-mail or by facsimile machine, receipt confirmed, (b) on the following business day, if delivered by
a nationally recognized overnight courier service, with receipt acknowledgement requested, or (c) three (3) business days after mailing, if sent by registered or certified mail, return receipt requested, postage prepaid, in each case, to
the Party to whom it is directed at the following address (or at such other address as any Party shall hereafter specify by notice in writing to the other Parties):

 Section 14.07 Independent Contractors. It is expressly agreed that BDSI and Purdue shall be
independent contractors and that the relationship between the two Parties shall not constitute a partnership or agency of any kind. Neither BDSI nor Purdue shall have the authority to make any statements, representations or commitments of any kind,

 Section 14.09 Publicity. Neither Purdue nor BDSI will make any public
announcement in respect of this Agreement or the matters contemplated hereby without the other Party’s prior written approval, such approval not to be unreasonably withheld, except as may be required by applicable law, rule, or regulation or
the rules and regulations of the Securities and Exchange Commission, any national securities exchange (including those located in countries outside of the United States) or the Nasdaq Stock Market, and provided that, notwithstanding anything to the
contrary, BDSI shall be entitled to announce or disclose that BDSI has earned any of the milestone payments described under Section 4.02 (which announcement may describe the triggering milestone event). Where a public announcement or disclosure
is required by required by applicable law, rule, or regulation or the rules and regulations of the Securities and Exchange Commission, any national securities exchange (including those located in countries outside of the United States) or the Nasdaq
Stock Market, or if BDSI is announcing or disclosing that BDSI has earned any of the milestone payments described under Section 4.02 (which announcement may describe the triggering milestone event), the Party required to make the announcement
or disclosure or BDSI, respectively, will, to the extent reasonably practicable, reasonably in advance of such announcement or disclosure (1) inform the other Party of the contents of the proposed announcement and (2) afford the other
Party a reasonable opportunity to comment on the announcement or disclosure in draft form. Notwithstanding the foregoing, no consent of any Party shall be required to release information which has previously been made public. Notwithstanding, and
without limitation of, the foregoing, both Parties shall use reasonable good faith efforts to agree on a press release to be issued promptly following the execution of this Agreement. Any notice to or request for approval to be made pursuant to this
Section 14.09 shall be made in accordance with Section 14.06, or by email to *** for Purdue or *** for BDSI, except that in the case of notices to or requests for approval from Purdue, a copy of such notices or requests for approvals shall
also be directed to, in addition to those persons named in Section 14.06, ***. 
 Section 14.10 Entire Agreement;
Amendment. This Agreement (including the Exhibits attached hereto), the Supply Agreement and, upon execution thereof by the Parties, the Quality Agreement and the Pharmacovigilance Agreement sets forth all of the covenants, promises,
agreements, warranties, representations, conditions and understandings between the Parties with respect to the subject matter hereof and supersedes and terminates all prior agreements and understandings between the Parties. There are no covenants,
promises, agreements, warranties, representations conditions or understandings, either oral or written, between the Parties other than as set forth herein. No subsequent alteration, amendment, change or addition to this Agreement shall be binding
upon the Parties unless reduced to writing and signed by the respective authorized officers of the Parties.

accountant selected by the Requesting Party (or any designee thereof) and reasonably acceptable to the Audited Party (with respect to inspections or audits directly concerning financial matters) or any designee selected by the Requesting Party and

but not limited to financial records) as may be necessary pursuant to the terms of the applicable Section of this Agreement granting the applicable audit and/or inspection rights to the
Requesting Party pursuant to this Section 14.11. For greater certainty, the Audited Party shall not disclose, nor be required to disclose, to the independent accounting firm, and the independent accounting firm shall not audit, inspect or
disclose to the Requesting Party, any competitively sensitive or strategic information of the Audited Party to the extent directly and solely related to any product other than the Licensed Product and/or any jurisdiction other than the Territory.
Any such independent accounting firm or designee shall be subject to the confidentiality provisions of this Agreement. In the case of any audit and/or inspection directly concerning financial matters, a copy of any report provided to a Party by the
accountant shall be given concurrently to the other Party and shall be considered the Audited Party’s Confidential Information. Subject to the terms of this paragraph, any such inspection or audit shall be conducted (a) at the sole cost of
the Requesting Party and (b) during the Audited Party’s normal business hours. If the applicable audit involves payments made and/or to be made by one Party to the other Party and such accounting firm concludes that there was an
overpayment or underpayment by one Party to the other Party with respect thereto, within *** of the date of delivery of such accounting firm’s report concluding that an overpayment or underpayment occurred, the amount overpaid shall be promptly
repaid by the overpaid Party or the amount underpaid shall be promptly augmented by the underpaying Party as necessary to correct the underpayment, and if there was an underpayment, the underpaying Party shall pay interest on the unpaid amount at
the rate set forth in Section 4.03(c). If the amount of such underpayment for any particular Calendar Quarter was equal to or greater than *** of the proper amount payable with respect to such Calendar Quarter, the Audited Party shall promptly
reimburse the Requesting Party for the reasonable, documented costs associated with the audit.
