Generally. Commencing upon the Effective Date and subject to Section 4 and other terms of this Agreement, as between Durect and Alpharma, Alpharma shall be responsible, at its sole Cost, for development of and procuring Regulatory Approval
for the Product in the Territory (all such activities the “Development Program”).

 (a) Development Plan. As of the Effective Date, the Parties have agreed upon a development plan (the “Development Plan”) covering
the activities necessary for developing the Product through Regulatory Approval in Subterritory A, including a budget (the “Development Plan Budget”), activities related to CMC development, Clinical and Non-Clinical development,
Regulatory Approval strategy, capital expenses that are specific to the Product, activities associated with manufacturing of Product for use in Clinical Trials, process development, scale-up for providing clinical supplies, and technology transfer
(including process development, scale up and validation activities) as needed to establish commercial scale manufacturing of the Product for Subterritory A, and other key elements reasonably necessary for the Parties to fulfill their development
responsibilities to each other under the terms of the Agreement. After the Effective Date, Alpharma shall thereafter update the

Development Plan in accordance with Alpharma’s normal planning cycle, but no less frequently than once a year, and provide a copy thereof to the JEC for
review and approval. In the event that the JEC does not unanimously approve any such update, then such matter shall be resolved in accordance with Section 2.1(d). 
 (b) Trials and Regulatory. Pursuant to the Development Plan and subject to this Section 4 and other terms of this Agreement, Alpharma shall use Commercially Reasonable Efforts to conduct such Preclinical
and Non-Clinical trials and Clinical Trials, at its own Cost, as necessary to seek and maintain Regulatory Approval of the Product in Subterritory A. Alpharma shall also use Commercially Reasonable Efforts to obtain Regulatory Approvals for the
Product in Subterritory A, including compiling, submitting and prosecuting all necessary data, documents and Regulatory Approval Applications (including labeling), in a format acceptable to the applicable Regulatory Authorities in Subterritory A. If
and when any Regulatory Approval is secured anywhere in Subterritory A, Alpharma shall thereafter use Commercially Reasonable Efforts to maintain such Regulatory Approval and pay all user fees and other costs required to maintain such Regulatory
Approval. 
 (c) Development Diligence. Alpharma shall use Commercially Reasonable Efforts to develop the Product through Regulatory
Approval in Subterritory A at its sole Cost. Without limiting the foregoing, Alpharma will use its Commercially Reasonable Efforts to perform the activities and to meet the timeline in the Development Plan. If, at any time, Alpharma materially
defaults on any of its development obligations with respect to Subterritory A set forth in Section 4 and fails to cure such default within [* * *] after receipt of written notice of termination from Durect, Durect shall have the right to
terminate Alpharma’s rights with respect to Subterritory A; provided, however, if the failure is not reasonably capable of being cured within the [* * *] cure period by Alpharma and Alpharma is making a good faith effort to cure
such failure, Durect may not terminate Alpharma’s rights in Subterritory A; provided further, however, that Durect may terminate Alpharma’s rights in Subterritory A if such failure is not cured within [* * *] of
Durect’s original notice of termination. In the event Durect terminates Alpharma’s rights with respect to Subterritory A hereunder: (i) Subterritory A shall thereafter be deemed a Terminated Country and no longer be included in the
Territory, and (ii) Durect shall have the rights set forth in Section 13.7 with

respect to Subterritory A. The foregoing termination rights of Durect shall be Durect’s sole and exclusive remedy and Alpharma’s sole and exclusive
liability for any failure by Alpharma to develop and Commercialize the Product in Subterritory A. 
 4.3 Development and Commercialization
Diligence Outside the U.S. 
 (a) Not later than [* * *] after the Effective Date, the Parties will jointly begin an assessment of the
market opportunity for the Product for Subterritories B, C and D and develop criteria for determining which such Jurisdictions present significant commercial potential for the Product and are subject to the obligations of this Section 4.3. Not
later than [* * *] after the Effective Date, the Parties will complete such assessment and the development of such criteria, and identify each Jurisdiction outside of the U.S. in which the development and Commercialization of Products by Alpharma
shall be subject to the obligations of this Section 4.3 (each such country, a “Major Market Jurisdiction”). Thereafter, the Parties shall review such designations annually and determine whether previously designated countries
should remain or cease to remain Major Market Jurisdictions and whether additional countries should be designated as Major Market Jurisdictions. If the Parties do not agree upon the designation of a country as a Major Market Jurisdiction or whether
a country should remain or cease to remain a Major Market Jurisdiction, the Parties shall submit the matter to the JEC for resolution in accordance with Section 2.1(d). Notwithstanding the foregoing provisions of this Section 4.3 relating
to the assessment, designation and review of Major Market Jurisdiction, the Jurisdictions listed on Schedule 4.3 are hereby categorized as Major Market Jurisdictions and shall not be subject to redesignation as non-Major Market Jurisdictions. Each
Party shall bear its own Costs incurred in assessing, designating and reviewing Major Market Jurisdictions in accordance with this Section 4.3(a). 
 (b) In at least one Major Market Jurisdiction (“First Major Market Jurisdiction”), Alpharma will either (i) initiate local Clinical Trials for a Product within [* * *] following U.S. Regulatory
Approval or (ii) if local Clinical Trials are not required for Regulatory Approval in the First Major Market Jurisdiction, file an application for Regulatory Approval within [* * *] following U.S. Regulatory Approval. In at least one additional
Major Market Jurisdiction (“Second Major Market Jurisdiction”), Alpharma will either (A) initiate local Clinical Trials for a Product within [* * *] following U.S. Regulatory Approval or (B) if

local Clinical Trials are not required for Regulatory Approval in the Second Major Market Jurisdiction, file an application for Regulatory Approval within [*
* *] following U.S. Regulatory Approval. If Subterritory C is not the First Major Market Jurisdiction or the Second Major Market Jurisdiction, then in addition to the foregoing requirements regarding the First Major Market Jurisdiction and the
Second Major Market Jurisdiction, Alpharma will either (A) initiate local Clinical Trials for a Product in Subterritory C within [* * *] following U.S. Regulatory Approval or (B) if local Clinical Trials are not required for Regulatory
Approval in Subterritory C, file an application for Regulatory Approval within [* * *] following U.S. Regulatory Approval. In all other Major Market Jurisdictions, Alpharma will use Commercially Reasonable Efforts to either (I) initiate local
Clinical Trials for a Product within [* * *] following U.S. Regulatory Approval or (II) if local Clinical Trials are not required for Regulatory Approval in any such other Major Market Jurisdiction, file an application for Regulatory Approval within
[* * *] following U.S. Regulatory Approval. For the avoidance of doubt, the filing of a Regulatory Approval Application with EMEA shall constitute filing of a Regulatory Approval Application in all Major Market Jurisdictions that are subject to
EMEA’s regulatory authority, and initiating Clinical Trials for the purpose of supporting the filing of a Regulatory Approval Application with EMEA shall constitute initiating local Clinical Trials with respect to all Major Market Jurisdictions
that are subject to EMEA’s regulatory authority. 
 (c) After satisfying the requirements of Section 4.3 with respect to a Major
Market Jurisdiction, Alpharma shall use Commercially Reasonable Efforts to obtain Regulatory Approval for and to Commercialize the Product in such Major Market Jurisdiction. [* * *]. 
 (d) If Alpharma fails to satisfy its obligations under this Section 4.3 with respect to a Major Market Jurisdiction, Durect shall thereafter have
the right to terminate Alpharma’s rights in such Major Market Jurisdiction if Alpharma has not cured such failure within the [* * *] period following written notice of termination by Durect; provided, however, if the failure is
not reasonably capable of being cured within the [* * *] cure period by Alpharma and Alpharma is making a good faith effort to cure such failure, Durect may not terminate Alpharma’s rights in such Major Market Jurisdiction; provided
further, however, that Durect

may terminate Alpharma’s rights in such Major Market Jurisdiction if such failure is not cured within [* * *] of Durect’s original notice of
termination. Notwithstanding the foregoing, Alpharma shall be deemed to have satisfied its obligations under this Section 4.3 and shall retain rights to all Jurisdictions in the EU provided that Alpharma has satisfied its development and
Commercialization obligations under this Section 4.3 in at least [* * *] of the Major Market Jurisdictions which are part of the EU. The Major Market Jurisdictions with respect to which Durect has terminated Alpharma’s rights hereunder
will thereafter be deemed Terminated Countries and no longer be included in the Territory, and Durect shall have the rights set forth in Section 13.7 in such Terminated Countries. The foregoing termination rights of Durect shall be
Durect’s sole and exclusive remedy and Alpharma’s sole and exclusive liability for any failure by Alpharma to develop and Commercialize the Product in any Major Market Jurisdiction.

the comments shall be provided promptly and reasonably in advance of any deadlines or target dates for submission. Alpharma shall promptly provide to Durect copies of or electronic access to material portions of all such filings and correspondence
from or to such Regulatory Authorities concerning the Product in Subterritory A and the Major Market Jurisdictions, provided that the Alliance Managers will (with oversight from the JDC) coordinate the scope, timing and form of all
such document access in a manner that seeks to minimize administrative burden. With regard to the NDA in Subterritory A, Durect shall, at Alpharma’s request, assist Alpharma in creating and finalizing Modules 2 and 3. In addition, Durect shall,
at Alpharma’s request, provide input for the creation and review of the Integrated Summary of Safety and the Integrated Summary of Efficacy. Upon request by Durect, other NDA sections or Modules will be available for review. At the request of
Alpharma, Durect shall participate, at Alpharma’s Cost, in any conference or meeting with Regulatory Authorities with respect to the Product in Subterritory A and the Major Market Jurisdictions. Alpharma shall notify Durect in writing of its

the conversion of the currency in which sales were made to Dollars over the calendar quarter during which such sales were made, as such rates are published by the Wall Street Journal, Western Edition. 
 7.4 Records Retention. Alpharma, its Sublicensees, Durect and each such Party’s respective Affiliates shall keep complete and accurate
records pertaining to Durect Development Costs and the sale of Product and the calculation of Net Sales in the Territory, as applicable, to permit the determination of Durect Development Costs and Royalties for a minimum period of [* * *] after the

accountant shall verify to the Auditing Party such amounts and shall disclose no other information revealed in such audit. The examination shall also include disclosure of the methodology and calculations used to determine the results. The said
independent, certified public accountant shall execute a written confidentiality agreement with the Audited Party. 
 7.6 Cost of
Audit. The Auditing Party shall bear the full Cost of the performance of any audit requested by the Auditing Party except as hereinafter set forth. If, as a result of any inspection of the books and records of the Audited Party, it is shown that
payments made by one Party to the other under this Agreement were less than the amount which should have been paid (in the case of Royalties) or the amount of costs charged by one Party to the other Party were more than the amount that should have
been charged (in the case of Durect Development Costs), then the under-paying or over-charging Party, as applicable, shall make all payments required to be made to eliminate any discrepancy revealed by said inspection within [* * *], including in
each case interest at the rate of [* * *] percent ([* * *]%) per month (or the maximum interest allowable by Applicable Law, whichever is less) for the amount of the discrepancy. Furthermore, if the payments made were less than [* * *] percent ([* *
*]%) of the amount that should have been paid during any calendar year, or if there was an overcharge of more than [* * *] percent ([* * *]%) of the amount of that was owed, in either case due to the error of the Audited Party, the Audited Party
shall also reimburse the Auditing Party for reasonable Costs incurred by the Auditing Party in respect of such audit.

 (b) With respect to Collaboration Inventions that do not constitute Product Collaboration Inventions, [* * *] such Collaboration Inventions (including
all Patents and other Intellectual Property Rights relating thereto) [* * *] its employees and/or Third Parties acting on behalf of Durect in the performance of the Development Plan and other activities undertaken by it under this Agreement (each
such Collaboration Invention a “[* * *]”). 
 (c) With respect to Collaboration Inventions that do not constitute Product
Collaboration Inventions, [* * *] such Collaboration Inventions (including all Patents and other Intellectual Property Rights relating thereto) [* * *] its employees and/or Third Parties acting on behalf of Alpharma in the performance of the
Development Plan and other activities undertaken by it under this Agreement (each such Collaboration Invention, an “[* * *]”). 
 (d) With respect to Collaboration Inventions that do not constitute Product Collaboration Inventions, the Parties shall jointly own all Joint Inventions (as defined below) and, subject to the rights granted each Party under this Agreement
and except as otherwise specifically provided under this Agreement, each Party may make, use, sell, keep, license or assign its interest in Joint Inventions and otherwise undertake all activities a sole owner might undertake with respect to such
Joint Inventions, without the consent of and without accounting to the other Party. “Joint Invention” means a Collaboration Invention which is not a Product Collaboration Invention for which: (i) one or more employees,
consultants or agents of Durect or any other persons obligated to assign such Collaboration Invention to Durect; and (ii) one or more employees, consultants or agents of Alpharma or any other persons obligated to assign

such Collaboration Invention to Alpharma, are joint inventors of such Collaboration Invention. The term “joint inventors,” as it applies generally
to Collaboration Inventions, shall be construed in accordance with how that term is used pursuant to United States patent law. 
 (e) Subject
to appropriate confidentiality undertakings, each Party shall notify the other Party promptly after the completion of invention disclosure statements (or similar type of internal process employed by such Party for recording or recognizing
inventions) for each Collaboration Invention (or, if any provisional or other patent application is filed claiming such invention, promptly upon such filing), and shall provide a copy of written documentation of the Collaboration Invention suitable
to describe the invention and identify any inventors participating in the invention (or, if any patent application is filed, a full and complete copy of the documents submitted to the relevant patent office) to the other Party. 
 (f) Each Party may use and practice its own Collaboration Inventions in any manner not inconsistent with the terms of this Agreement without the consent
of the other Party and without an obligation to notify the other Party of such intended use or to pay royalties or other compensation to the other by reason of such use. For the avoidance of doubt, neither Party is granted any license rights to any
Intellectual Property Rights of the other Party which may be required for such Party to use a Collaboration Invention, unless otherwise expressly granted herein or as may be necessary to fulfill the intent of this Agreement. 
 (g) Each Party shall, at the request of the other Party, execute all assignment documents necessary to perfect the ownership interests in Collaboration
Inventions as determined pursuant to this Section 9.1. Each Party hereby agrees that Development Data owned by such Party may be included in patent and patent applications covering Collaboration Inventions owned by the other Party as reasonably
useful to the filing and prosecution of such patent applications and patents, and the Party owning such Development Data shall reasonably cooperate with the other Party to allow for such inclusion. 
 (h) Each Party has and will continue to have written contracts with all Third Parties (including employees and subcontractors) performing services on its
behalf under this Agreement and, where such services may give rise to the creation of inventions that may be Collaboration Inventions, such Party shall ensure that such contracts provide for the

assignment to such Party all Collaboration Inventions and rights therein; provided, however, notwithstanding the foregoing, Alpharma may enter
into Third Party contract manufacturing agreements for the sole purpose of having the Product manufactured for Alpharma that do not require such Third Party manufacturers to assign any Collaboration Inventions that are manufacturing process
inventions to Alpharma if such Third Party manufacturers do not agree to the assignment of such manufacturing process Collaboration Inventions. 
 9.2 Prosecution of Patents. 
 (a) Durect Controlled Patents. 
 (i) As between Durect and Alpharma, Durect shall prepare, prosecute and maintain the [* * *] Product Patent Rights and [* * *] (including
their issuance, reissuance, reexamination and the defense of any interference, revocation or opposition proceedings) at Durect’s sole Cost and discretion subject to the provisions of this Section 9.2(a). 
 (ii) With respect to Product Patent Rights, Durect shall furnish Alpharma with copies of all substantive prosecution correspondence to and
from patent offices in the Territory and provide Alpharma a reasonable time to offer its comments thereon before Durect makes a submission to the relevant patent office, provided that in the event that delay would jeopardize any potential
Product Patent Right, Durect shall have the right to proceed without awaiting Alpharma’s comments on any patent application or correspondence relating thereto. Alpharma shall offer its comments promptly, and Durect shall consider in good faith
such comments of Alpharma and shall incorporate such comments if reasonable. Durect shall not abandon any patent application or patent in the Product Patent Rights without the prior written consent of Alpharma, such consent not to be unreasonably
withheld or delayed. If, subject to Alpharma’s foregoing consent right, Durect determines to abandon, or not to file, prosecute, defend or maintain, any Product Patent Right (including not to defend any interference,
revocation or opposition proceedings) in any Jurisdiction, then Durect shall provide Alpharma with [* * *] prior written notice (or such shorter time period that would permit Alpharma a reasonable opportunity to respond without any loss of
rights)

of such determination, and Alpharma shall have the right and opportunity to file, prosecute, defend and/or maintain such Product Patent Right in
Durect’s name and at Alpharma’s sole Cost and expense, provided, however, that the payment of Costs therefor by Alpharma shall not affect Durect’s ownership in such Patent. 
 (b) Joint Patents. With respect to the decision to initiate the drafting and filing of a new patent application claiming a Joint Invention, the
Parties shall first exchange sufficient information identifying such Joint Invention and discuss in good faith the relative merits of seeking patent rights thereto and, upon the prior mutual agreement of the Parties to proceed, not unreasonably
withheld, Alpharma shall take such actions as are necessary or appropriate to procure, prosecute and maintain patents and/or patent applications to such Joint Inventions (“Joint Patent Rights”) (including any issuance, reissuance or
reexamination thereof and the defense of any interference, revocation or opposition proceedings related thereto) at Alpharma’s sole Cost and discretion, subject to the provisions of this Section 9.2(b); provided, that all such Joint
Patents shall be owned jointly. Alpharma shall furnish Durect with copies of drafts of such Joint Patents and any substantive prosecution correspondence relating to such Joint Inventions to and from patent offices throughout the Territory and permit
Durect to offer its comments thereon before Alpharma makes any submission or response to a patent office. Alpharma will inform Durect of the countries in which it intends to file Joint Patents. Durect shall offer its comments promptly, including any
request that the Joint Patents be filed in additional countries; provided, that Alpharma shall determine the appropriate action after considering in good faith any comments or requests from Durect, and further provided that in the
event that delay would jeopardize any potential patent right, Alpharma shall have the right to proceed without awaiting Durect’s comments. If Alpharma determines in its sole discretion not to file, prosecute, defend or maintain any Joint Patent
Rights (including failing to defend any interference, revocation or opposition proceedings) in any country, then Alpharma shall provide Durect with [* * *] prior written notice (or such shorter time period that would permit Durect a reasonable
opportunity to respond in a timely manner) of such determination, and Durect shall have the right and opportunity to file, prosecute, defend and/or maintain such Joint Patent Rights on behalf of the Parties at Durect’s sole Cost.

maintain all Patents claiming an Alpharma Collaboration Invention (including their issuance, reissuance, reexamination and the defense of any interference, revocation or opposition proceedings) at Alpharma’s sole Cost and discretion.

 (d) Each Party shall, at the reasonable request of the other Party, execute all lawful papers, all divisional, continuing, reissue and
foreign applications, make all rightful oaths and take such other actions as may be reasonably requested by the other Party in conjunction with submission, filing, prosecution and defense of Patents and to aid in obtaining the proper protection of
inventions pursuant to this Section 9.2. 
 9.3 Patent Certifications. 
 (a) To the extent required or permitted by Applicable Laws, [* * *] shall use its Commercially Reasonable Efforts to maintain with the applicable
Regulatory Authorities in the Territory during the Term of this Agreement correct and complete listings of applicable Patents covering the Product, including in the U.S., all so called “Orange Book” listings required under the Hatch-Waxman
Act. In the event either Party receives notice that a Third Party has filed a patent certification under the Hatch-Waxman Act or any successor statute (e.g., a Paragraph IV Certification under 21 C.F.R. §314.50(i) or 314.94(a)(12)) referencing
a Patent licensed under Section 3.1, then such Party shall immediately notify the other Party in writing of such notice. 
 (b) Alpharma
shall have the first right, but not the duty, upon written notice to Durect to institute an action against such Third Party alleging infringement of any Product Patent Rights, and to the extent necessary, Durect shall assign to Alpharma its cause of
action for infringement of any Product Patent Rights against such Third Party. Alpharma shall consider in good faith all comments provided by Durect within the [* * *] period following Durect’s receipt of such notice from Alpharma regarding
Alpharma’s intention to initiate an action against such Third Party alleging infringement of any Product Patent Rights; provided that, subject to terms of Section 9.3(d), Alpharma shall have the sole discretion and authority to
exercise its first right to institute such a patent infringement action. If Alpharma determines not to institute an action against such Third Party alleging infringement of any Product Patent Rights, Alpharma shall so notify Durect at least [* * *]

such an action against such Third Party alleging infringement of any Product Patent Rights. 
 (c) As between Durect and Alpharma, Durect
shall have the first right, but not the duty, upon written notice to Alpharma to institute an action against a Third Party for infringement of the [* * *] in response to such Third Party’s filing of a Paragraph IV certification referencing such
Patent rights. Durect shall consider in good faith all comments provided by Alpharma within the [* * *] period following Alpharma’s receipt of such notice from Durect regarding Durect’s intention to initiate an action against such Third
Party alleging infringement of the [* * *]; provided that, subject to terms of Section 9.3(d), Durect shall have the sole discretion and authority to exercise its first right to institute such a patent infringement action. If Durect
determines not to institute an action against such Third Party alleging infringement of the [* * *], Durect shall so notify Alpharma at least [* * *] before the expiration of the period within which a patent holder may bring an action for
infringement against such Third Party. Alpharma shall then have the right, but not the duty, to institute such an action against such Third Party alleging infringement of the [* * *]; provided, however, that Alpharma’s right to undertake any
such action alleging infringement of the [* * *] shall be subject to the prior written consent of Durect, not to be unreasonably withheld, and also the applicable terms of any agreements relating to the [* * *] entered into by Durect prior to the
Effective Date, and with respect any actions alleging infringement of the [* * *], subject to the applicable terms of the [* * *] Agreement. 
 (d) The Costs of any such action under this Section 9.3 (including fees of attorneys and other professionals) shall be borne by the Party instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such
action, such Costs shall be borne by the Parties in such proportions as they may agree in writing. For any such action to terminate any such infringement, in the event that either Party is unable to initiate or prosecute such action solely in its
own name or it is otherwise advisable to obtain an effective remedy, the other Party will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for the enforcing Party to initiate and maintain such
action. Each Party shall at its own expense promptly give to the Party bringing such infringement

proceedings such reasonable assistance as the Party bringing the action may reasonably request. The Party instituting any such action may not enter into any
settlement, consent judgment or other voluntary final disposition of such action that admits the invalidity or unenforceability of any Patent licensed hereunder, subjects the other Party to an injunction or requires the other Party to make any
monetary payment without the prior written consent of the other Party, not to be unreasonably withheld by the other Party. The Party undertaking any proceedings shall keep the other reasonably informed of the progress of the action and shall
consider the comments and observations of the other in prosecuting the proceedings. Any award paid by a Third Party as a result of such an infringement action (whether by way of settlement or otherwise) shall be allocated in the same manner as
provided in Section 9.4.  
 9.4 Enforcement of Patent Rights. 
 (a) In the event that either Alpharma or Durect becomes aware of any Competitive Product that is or is intended to be made, used, or sold in the Territory
by a Third Party that it believes to infringe Product Patent Rights, [* * *], such Party will promptly notify the other Party of all the relevant facts and circumstances known by it in connection with the infringement. Alpharma and Durect shall
thereafter consult and cooperate fully to determine a course of action, including the commencement of legal action as provided in this Section 9.4 by either or both Parties, to terminate any such infringement. 
 (b) As between Durect and Alpharma, Alpharma shall have the first right, but not the duty, upon written notice to Durect to initiate, prosecute and
control the enforcement of any of the Product Patent Rights against infringement by a Third Party in the Territory through the marketing or sale of a Competitive Product. If Alpharma does not institute a proceeding against such Third Party alleging
infringement of a Product Patent Right within 180 days of a Party’s first notice to the other Party of such Third Party infringement, then Durect shall have the right, but not the duty, to institute such an action against such Third Party for
infringement of such Product Patent Right. 
 (c) As between Durect and Alpharma, Durect shall have the first right, but not the duty, upon
written notice to Alpharma to initiate, prosecute and control the enforcement of any of the [* * *] against infringement by a Third Party in the Territory through the marketing

or sale of a Competitive Product. If Durect does not institute a proceeding against such Third Party alleging infringement of the [* * *] within [* * *] of a
Party’s first notice to the other Party of such Third Party infringement, then Alpharma shall have the right, but not the duty, to institute such an action against such Third Party for infringement of any of the [* * *]; provided, however, that
Alpharma’s right to undertake any such action alleging infringement of the [* * *] shall be subject to the prior written consent of Durect, not to be unreasonably withheld and also the applicable terms of any agreements relating to the [* * *]
entered into by Durect prior to the Effective Date, and with respect any actions alleging infringement of the [* * *], subject to the applicable terms of the [* * *] Agreement. 
 (d) The Costs of any such action under this Section 9.4 (including fees of attorneys and other professionals) shall be borne by the Party
instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such Costs shall be borne by the Parties in such proportions as they may agree in writing. For any such action to terminate any such
infringement, in the event that either Party is unable to initiate or prosecute such action solely in its own name or it is otherwise advisable to obtain an effective remedy, the other Party will join such action voluntarily and will execute and
cause its Affiliates to execute all documents necessary for the enforcing Party to initiate and maintain such action. Each Party shall at its own expense promptly give to the Party bringing such infringement proceedings such reasonable assistance as
the Party bringing the action may reasonably request. The Party instituting any such action may not enter into any settlement, consent judgment or other voluntary final disposition of such action that admits the invalidity or unenforceability of any
Patent licensed hereunder, subjects the other Party to an injunction or requires the other Party to make any monetary payment without the prior written consent of the other Party, not to be unreasonably withheld by the other Party. The Party
undertaking any proceedings shall keep the other reasonably informed of the progress of the action and shall consider the comments and observations of the other in prosecuting the proceedings. 
 (e) Any recovery obtained as a result of an infringement action brought under this Section 9.4, whether by judgment, award, decree or settlement,
will first be applied to reimbursement of each Party’s Costs in bringing such suit or proceeding, and any remaining balance will be distributed as follows: 
 (i) if Alpharma has instituted and maintained such action alone, Alpharma shall be entitled to retain [* * *] less [* * *], which [* * *]
shall be paid to Durect. The “[* * *]” shall mean [* * *] in the Annual Net Sales Period in which such remaining funds are received on such remaining funds [* * *];

entitled to retain [* * *] less the [* * *], which [* * *] shall be paid to Alpharma; or 
 (iii) if the Parties have
cooperated in instituting and maintaining such action, the Parties shall allocate such remaining funds among themselves in the same proportion as they have agreed to bear the Costs of instituting and maintaining such action. 
 9.5 Defense of Patents. 
 (a) In the
event that either Alpharma or Durect becomes aware of any action initiated by a Third Party (or any counterclaim or defense asserted in any other action) in the Territory alleging invalidity or unenforceability of any Product Patent Rights, [* * *],
such Party will promptly notify the other Party of all the relevant facts and circumstances known by it in connection with such action. Alpharma and Durect shall thereafter consult and cooperate fully to determine a course of action. 
 (b) Alpharma shall have the first right but not the duty to defend and control any action initiated by a Third Party (or any counterclaim or defense
asserted in any other action) in the Territory alleging invalidity or unenforceability of any Product Patent Rights. If Alpharma fails to defend any such action initiated by a Third Party (or any counterclaim or defense asserted in any other action)
within [* * *] of notice from such Third Party (or such shorter time period that would permit Durect a reasonable opportunity to respond in a timely manner), Durect shall thereafter have the right to defend and control any such invalidity action,
counterclaim or defense in the Territory. 
 (c) Durect shall have the first right but not the duty to defend and control any action
initiated by a Third Party (or any counterclaim or defense asserted in any other action) in the Territory alleging invalidity or unenforceability of the [* * *]. If Durect fails to defend

any such action initiated by a Third Party (or any counterclaim or defense asserted in any other action) within [* * *] of notice from such Third Party (or
such shorter time period that would permit Alpharma a reasonable opportunity to respond in a timely manner), then Alpharma shall have the right, but not the duty, to defend and control any such invalidity action, counterclaim or defense in the
Territory; provided, however, that Alpharma’s right to undertake any the defense of such action relating to the [* * *] shall be subject to the prior written consent of Durect, not to be unreasonably withheld and also the applicable terms of
any agreements relating to the [* * *] entered into by Durect prior to the Effective Date, and with respect any actions defending the [* * *], subject to the applicable terms of the [* * *] Agreement. 
 (d) The Costs of any such action under this Section 9.5 (including fees of attorneys and other professionals) shall be borne by the Party defending
the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such Costs shall be borne by the Parties in such proportions as they may agree in writing. For any such action, in the event that either Party is unable to
defend such action solely in its own name or it is otherwise advisable to obtain an effective remedy, the other Party will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for the defending
Party to defend such action. Each Party shall at its own expense promptly give to the defending Party such reasonable assistance as the Party defending the action may reasonably request. The defending Party may not enter into any settlement, consent
judgment or other voluntary final disposition of such action that admits the invalidity or unenforceability of any Patent licensed hereunder, subjects the other Party to an injunction or requires the other Party to make any monetary payment without
the prior written consent of the other Party, not to be unreasonably withheld by the other Party. The Party undertaking any such defense shall keep the other reasonably informed of the progress of the action and shall consider the comments and
observations of the other in the proceedings. 
 9.6 Patent Infringement Claims. 
 (a) Each Party shall notify the other Party promptly in writing of any claim of, or action for, infringement of any Patents or misappropriation of trade
secret rights of any Third Party that is threatened, made or brought against either Party by reason of the development, manufacture, use, sale, offer for sale, importation or exportation of the Product in the Territory.

 (b) In the event of the institution of any suit by a Third Party against either Party for Patent
infringement involving the development, manufacture, use, sale, offer for sale, importation or exportation by or on behalf of Alpharma, its Affiliates or Sublicensees of the Product in the Territory after the Effective Date, Alpharma shall be
responsible for the defense of any such suit and, subject to the terms of this Section 9.6, Alpharma shall control such defense. Alpharma shall select defense counsel and, provided that Alpharma can do so without compromising attorney-client
privilege, regularly consult with Durect and its counsel to keep them reasonably informed on the progress and status of the suit. Durect shall assist Alpharma and cooperate in any such litigation at Alpharma’s request and Cost. No settlement,
compromise or other disposition of any such proceeding that subjects Durect to an injunction or requires Durect to make any monetary payment shall be entered into without Durect’s prior written consent, which consent will not be unreasonably
withheld. Notwithstanding the foregoing, Alpharma shall not have any obligation to defend Durect against any Third Party Patent infringement suit arising out of any breach by Durect of its representations and warranties hereunder. 
 (c) Alpharma shall be responsible for all Costs to defend any suit that it is responsible for under this Section 9.6, including all fees and costs
of attorneys, expert witnesses and other out-of-pocket litigation costs and all damages, penalties, court costs, attorney fees and other payments payable to any such Third Party, whether as a result of any judgment, award, settlement or otherwise
(such liability, “Patent Litigation Losses”); provided, however, Alpharma may offset [* * *] percent ([* * *]%) of all such Patent Litigation Losses against any future Royalties due to Durect for Net Sales in such applicable
Jurisdiction(s), provided that any such set-off (by itself or in combination with other set offs) may not reduce the Royalties to Durect for Net Sales in such applicable Jurisdiction(s) by more than [* * *] percent ([* * *]%) in any calendar
quarter. Without limiting Durect’s liability for any breach of Durect’s representations and warranties hereunder, Durect’s sole liability and Alpharma’s exclusive remedy against Durect for any Patent Litigation Losses shall be
Alpharma’s right of offset in accordance with Section 9.6(c).

 (d) In the event a Third Party threatens suit against either Party for Patent infringement involving
the development, manufacture, use, sale, offer for sale, importation, exportation, license or marketing of the Product in the Territory, the Parties shall confer with respect to the appropriate course of action, and if they determine that a
declaratory action is warranted, then with respect to such action, the provisions of this Section 9.6 shall apply thereto with respect to the prosecution of such action and the defense of any claims asserted in response thereto. 
 (e) In the event that either Party becomes aware of a Third Party Patent, under which, in the good faith reasonable judgment of such Party, it would be
advisable to obtain a license to avoid infringement or potential infringement by the development, manufacture or Commercialization of the Product in any Jurisdiction, such Party shall promptly notify the other Party. The Parties shall then confer in
good faith with respect to the appropriate course of action. Alpharma shall have the right to negotiate and obtain such a license and, subject to the terms of this Section 9.6(e) below and without limiting Durect’s liability for any breach
of its representations and warranties hereunder, Alpharma shall be solely responsible for all costs and obligations under such license (the “Third Party License Fees”), provided, however, that Alpharma may offset [* * *]
percent ([* * *]%) of all such Third Party License Fees against any future Royalties due to Durect for Net Sales in such applicable Jurisdiction(s) provided that any such set-off (by itself or in combination with other set offs) may not reduce the
Royalties to Durect for Net Sales in such applicable Jurisdiction(s) by more than [* * *] percent ([* * *]%) in any calendar quarter. Alpharma shall provide Durect with complete copies of the license agreement with such Third Party and other
material information in its possession in respect of such technology subject to any confidentiality provisions imposed by such Third Party. 
 9.7 Patent Term Extensions. Alpharma may select which, if any, Patents other than the [* * *] licensed hereunder for which patent term extension, adjustment or restoration or supplemental protection certificates (together with patent
term extensions, adjustments and restorations, collectively “Patent Term Extensions”) is to be sought or obtained. Subject to the terms of this Section 9.7, Alpharma will file for all such Patent Term Extensions at
Alpharma’s expense, and Durect will execute such authorizations and other documents and take such other actions as may be reasonably requested to obtain such Patent Term Extensions, including designating Alpharma as its agent for such purpose.

 9.8 Prosecution of Durect Trademark. Durect shall use Commercially Reasonable Efforts to
register and maintain, or cause to be registered and maintained, the Durect Trademark in Jurisdictions as agreed upon by the Parties at Alpharma’s Cost. Durect shall furnish Alpharma with copies of all substantive prosecution correspondence to
and from trademark offices in the Territory and provide Alpharma a reasonable time to offer its comments thereon before Durect makes a submission to the relevant trademark office, provided that in the event that delay would jeopardize any
potential rights, Durect shall have the right to proceed without awaiting Alpharma’s comments on any application or correspondence relating to the Durect Trademark. Alpharma shall offer its comments promptly, and Durect shall consider in good
faith such comments of Alpharma and shall incorporate such comments if reasonable. Alpharma shall use the Durect Trademark, and all Products bearing the Durect Trademark shall be manufactured, in accordance with the trademark usage and quality
standards established by the JEC and approved by Durect, such approval not to be unreasonably withheld nor delayed; provided that, on a Jurisdiction-by-Jurisdiction basis, the JEC shall, if commercially reasonable, adopt any trademark
usage and quality standards timely proposed by Durect to the JEC prior to the First Commercial Sale in such Jurisdiction. 
 9.9
Enforcement of Durect and Product Trademarks. If either Party learns of any infringement or threatened infringement by a Third Party of the Durect Trademark or a Product Trademark in the Territory, such Party shall as soon as reasonably
practicable notify the other Party and will provide such other Party with all available evidence of such infringement or threatened infringement. Alpharma shall have the right, but not the obligation, to institute, prosecute and control, at its own
Cost, any action or proceeding with respect to any infringement or threatened infringement by a Third Party of the Durect Trademark or any Product Trademark in the Territory, by counsel of its own choice and, provided that Alpharma can do so without
compromising attorney-client privilege, shall regularly consult with Durect and its counsel to keep them reasonably informed on the progress and status of the suit. For any such action to terminate any such infringement, in the event that Alpharma
is unable to initiate or prosecute such action solely in its own name or it is otherwise advisable to obtain an effective remedy,

Durect will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for Alpharma to initiate litigation and
maintain such action. Alpharma will control the action, including settlement thereof; provided, that no settlement or consent judgment or other voluntary final disposition of any such action brought by Alpharma to enforce the Durect Trademark
in the Territory pursuant to this Section 9.9 may be entered into without the prior written consent of Durect, such consent not to be unreasonably withheld, if such settlement would adversely affect the Durect Trademark (e.g., restrict the
rights or admit invalidity). Any damage award or other consideration resulting from any such action or proceeding shall be retained by Alpharma. 
 9.10 Maintenance of [* * *] Agreements. Until the expiration or termination of this Agreement, or in the case of the [* * *] Agreement, until such agreement is assigned to Alpharma, Durect: (a) shall not breach, or default under the
[* * *] Agreement or [* * *] Agreement, which breach or default would give rise, whether immediately or with the passage of time, to termination of the [* * *] Agreement or [* * *] Agreement or to any restriction of Durect’s rights thereunder

Party that may disclose Collaboration Inventions shall comply with this Section 10. At least [* * *] before a manuscript is to be submitted to a publisher,
the publishing Party will provide the other Party with a copy of the manuscript. If the publishing Party wishes to make an oral or visual presentation, it will provide the other Party with a summary of such presentation at least [* * *] before such
oral or visual presentation and, if an abstract is to be published, [* * *] before such abstract is to be submitted. Any oral or visual presentation, including any question period, shall not include any Confidential Information belonging to a Party
unless such Party agrees in writing to such inclusion in advance of such oral presentation. 
 10.2 Review. The other Party will
review the manuscript, abstract, text or any other material provided to it under Section 10.1 to determine whether patentable subject matter or valuable trade secrets of the reviewing Party are disclosed and to assess the accuracy of the
technical content therein. The other Party will notify the publishing Party within [* * *] of receipt of the proposed publication if such Party, in good faith, determines that patentable subject matter or valuable trade secrets of the reviewing
Party are or may be disclosed, or if the other Party, in good faith, believes Confidential Information of the reviewing Party is or may be disclosed. If it is determined by the other Party that patent applications should be filed in advance of the
proposed publication, the publishing Party shall delay its publication or presentation for a period not to exceed [* * *] from the other Party’s receipt of the proposed publication or presentation to allow time for the filing of patent
applications covering patentable subject matter. In the event that the delay needed to complete the filing of any necessary patent application will exceed the [* * *] period, the other Party will discuss the need for obtaining an extension of the
publication delay beyond the [* * *] period. If it is determined in good faith by a Party that Confidential Information or proprietary information of such Party is being disclosed, the Parties shall consult in good faith to arrive at an agreement on
mutually acceptable modifications to the proposed publication or presentation to avoid such disclosure. Any publications (whether written or oral), where consistent with customary academic practice, shall acknowledge Durect as the developer and
licensor of the Product. 
 10.3 Publicity. Neither Party shall make any public announcement concerning the existence of or the terms
of this Agreement and Durect shall not make any public announcement regarding the development or Commercialization of the Product in the Territory, without the

prior written approval of the other Party with regard to the form, content and precise timing of such announcement, except such as may be required to be made
by either Party in order to comply with applicable law, regulations, court order, or tax or securities filings. Such consent will not be unreasonably withheld or delayed by such other Party. Prior to any such public announcement requiring the other
Party’s prior written approval, the Party wishing to make the announcement will submit a draft of the proposed announcement to the other Party not less than [* * *] in advance to enable the other Party to consider and comment thereon. Failure
to respond with comments in writing prior to [* * *] before scheduled release shall be deemed approval of such release. Notwithstanding anything to the contrary in this Agreement, nothing in this Section 10.3 is intended to prohibit either
Party from republishing or restating information that has already been approved by the other Party for use in a prior press release or public announcement. Alpharma shall notify Durect in advance (at least [* * *] in advance if commercially
reasonable) of written public announcements or presentations and shall use reasonable efforts to notify Durect in advance of oral public announcements, in each case, by Alpharma of material new information regarding the development or
Commercialization of the Product and of public announcements by Alpharma of results of Clinical Trials. Any written public announcements or presentations shall include a standard statement in a form agreed to by the Parties stating that the Product
has been licensed from Durect.

agreed in writing, the Parties agree that, during the Term of this Agreement and for [* * *] thereafter, the receiving Party, its Affiliates and its designees shall, and shall ensure that their respective employees, officers, directors and other
representatives shall, keep confidential and not publish or otherwise disclose and not use for any purpose, other than the development and Commercialization of the Product in the Territory, any information including all Know-How furnished to it by
the other Party, its Affiliates or its designees, except to the extent that it can be established by the receiving Party by competent proof that such information: (i) was already known to the receiving Party, other than under an obligation of
confidentiality, at the time of disclosure by the disclosing Party; (ii) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party; (iii) became generally available to

obligation of confidentiality, by a Third Party who had, to the receiving Party’s knowledge, no legal obligation not to disclose such information to others; or (v) was independently generated by the receiving Party without reference to
Confidential Information of the disclosing Party (all such information to which none of the foregoing exceptions applies, and the terms of this Agreement, shall be deemed “Confidential Information”). Any and all information, data
and materials, including any and all Intellectual Property Rights therein and thereto, owned by a Party shall constitute Confidential Information of such Party which shall be deemed the disclosing Party with respect to such Confidential Information
for the purposes of this Section 10. Notwithstanding the foregoing, the obligations of confidentiality under this Section 10.4 regarding any Confidential Information relating to or containing a Party’s trade secret that has been
suitably identified to the other Party as such shall continue beyond the period set forth in this Section 10.4 (i.e., the Term plus [* * *]) so long as the subject matter remains a trade secret.

consulting, development, manufacturing, external testing, or Commercialization of the Product or in connection with a proposed financing transaction, merger, acquisition or other change of control of a Party or sale of all or substantially all of
the assets of a Party; or (iii) is otherwise required to be disclosed in compliance with applicable laws or regulations or order by a court or other regulatory body having competent jurisdiction, including ; provided that, if a Party is
required to make any such disclosure of the disclosing Party’s Confidential Information, such Party will, except where impracticable for necessary disclosures (for example, to physicians conducting studies or to health authorities), give
reasonable advance notice to the disclosing Party of such disclosure requirement and reasonably cooperate with the disclosing Party to secure confidential treatment of such Confidential Information required to be disclosed. 
 10.6 Limitations on Use. Each Party shall use, and cause each of its Affiliates and its licensees to use, any Confidential Information obtained by
such Party from the disclosing Party, its Affiliates or its licensees, pursuant to this Agreement or otherwise, solely in connection with the activities or transactions contemplated by this Agreement.

Alpharma of its representations and warranties hereunder or (ii) the development or Commercialization of the Product by Alpharma, its Sublicensees,
Affiliates or designees under this Agreement. 
 12.3 Shared Liability. If Damages arise out of Third Party claims that are subject to
indemnification by Alpharma under Section 12.2 and also subject to indemnification by Durect under Section 12.1, then the Parties shall indemnify each other to the extent of their respective liability for the Damages. In the event that the
Parties cannot agree to their respective indemnity obligations hereunder, a Party shall be free at any time to seek resolution of the respective indemnity obligations of the Parties under this Section 12 pursuant to the provisions set forth in
Section 14.12. 
 12.4 Indemnification Procedure. Upon receipt by the Party seeking indemnification hereunder (an “Indemnified
Party”) of notice of any action, suit, proceeding, claim, demand or assessment against such Indemnified Party which might give rise to Damages, the Indemnified Party shall give prompt written notice thereof to the Party from which
indemnification is sought (the “Indemnifying Party”) indicating the nature of the claim and the basis therefore, provided that the failure to give such prompt notice shall not relieve the Indemnifying Party of its obligations
hereunder except to the extent the Indemnifying Party or the defense of any such claim is materially prejudiced thereby. The Indemnifying Party shall have the right, at its option, to assume the defense of, at its own Cost and by its own counsel,
any such claim involving the asserted liability of the Indemnified Party. If any Indemnifying Party shall undertake to compromise or defend any such asserted liability, it shall promptly notify the Indemnified Party of its intention to do so, and

settlement or other compromise, admit to liability for which the Indemnifying Party is not fully indemnifying the Indemnified Party or agree to an injunction with respect to activities of the Indemnified Party without the written consent of the
Indemnified Party. Notwithstanding an election by the Indemnifying Party to assume the defense of any claim as set forth above, such Indemnified Party shall have the right (at its own Cost if the Indemnifying Party has elected to assume such
defense) to employ separate counsel and to participate in the defense of any claim.

	13.	TERM AND TERMINATION 

 13.1 Term of Agreement. This
Agreement shall become effective as of the Effective Date and remain in effect on a Jurisdiction-by-Jurisdiction basis until the expiration of the applicable Royalty Term or earlier termination of this Agreement (the “Term”). Upon
the expiration of the applicable Royalty Term in a Jurisdiction (but not upon the earlier termination of this Agreement), the rights and licenses granted to Alpharma under this Agreement with respect to the Product in such Jurisdiction shall convert
to fully paid-up, non-royalty-bearing, perpetual rights and licenses. 
 13.2 Condition Precedent  
 (a) HSR Compliance. Each Party shall use commercially diligent efforts to satisfy any applicable requirements under the HSR, and the regulations
promulgated thereunder, including by making an initial HSR filing as soon as practicable after the Execution Date. This Agreement will not be effective until the date (“Effective Date”) of satisfaction of any such requirements and
the expiration or termination of all applicable waiting periods (including any early termination or extensions thereof). The obligations, rights, duties and liabilities under this Agreement (except those contained in this Section 13.2 and
Sections 10 and 11 of this Agreement) shall not be effective until the Effective Date. 
 (b) Cooperation. Each Party shall cooperate
with the other Party in the prompt preparation, execution and filing of all documents that are required or permitted to be filed pursuant to HSR, and to notify the other Party upon receipt of any formal or informal requests for information from any
antitrust agency in connection with any filings under HSR. Each Party shall bear its own Costs with respect thereto (provided, however, the filing fees for HSR, if applicable, shall be paid by Alpharma). 
 (c) Termination Right. If the Effective Date has not occurred within six (6) months after the Execution Date, notwithstanding that each Party
having fulfilled its obligations under this Section, either Party has the right to terminate this Agreement without liability to the other Party by notice in writing with immediate effect.

 13.3 Termination by Alpharma. 
 (a) Without Cause. Alpharma may terminate this Agreement without cause upon six (6) months’ prior written notice at any time. In such
event, during the six-month notice period, [* * *] provided that it shall not be obligated to [* * *]; provided that, (i) [* * *] and (ii) if [* * *]. 
 (b) Safety. If during the development or commercialization of the Product, the Product becomes subject to one or more Serious Adverse Drug Experiences (as defined below) or either Party receives notice from a
regulatory authority, independent review committee, data safety monitoring board or another similar Clinical Trial or post-marketing monitoring body alleging significant concern regarding a patient safety issue, in each case which Alpharma, in good
faith, reasonably believes would seriously impact the long-term viability of the Product, Alpharma shall have the right, upon [* * *] prior written notice to Durect setting forth the reasons therefor, to have the JEC determine whether or not there
exists such serious impact on the long-term viability of the Product and what, if anything, the Parties should do to address the matter. In the event the JEC is unable to reach consensus on resolution of the matter within [* * *] of the matter being
referred to the JEC, Alpharma may terminate its rights and obligations under this Agreement upon written notice so long as Alpharma reasonably believes the patient safety issue would seriously impact the long-term viability of the Product. During
the foregoing notice and resolution periods, Alpharma may take any actions that it reasonably determines are necessary to address such safety concerns. For purposes of this Agreement, a “Serious Adverse Drug Experience” means any
adverse drug experience occurring at any dose that results in any of the following outcomes: death, a life-threatening adverse drug experience, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant
disability/incapacity, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered a Serious Adverse Drug Experience when, based upon appropriate
medical judgment, they may jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. 
 13.4 Termination for Material Breach. Upon the material breach by one Party under this Agreement, the other Party shall notify the breaching Party of such breach, and require that the breaching Party cure such
breach within [* * *] or, in the case of payment defaults, within [* * *],

or in the case of a breach that cannot be cured within [* * *], within a reasonable period not exceeding [* * *] so long as the breaching party is diligently
proceeding to cure such default. In the event that a material breach by such Party is not cured within the applicable cure period and without limiting other available remedies, the other Party shall have the right to terminate this Agreement upon
written notice. Notwithstanding the foregoing provisions of this Section 13.4, (a) the provisions of Sections 4.2(c) and 4.3(d) and not this Section 13.4 shall control the Parties’ remedies and liabilities with respect to the
matters set forth therein and (b) in the case of any bona fide dispute regarding an alleged material breach that is submitted to arbitration pursuant to Section 14.12, the non-breaching Party shall not have the right to terminate this
Agreement pursuant to this Section 13.4 until a final arbitration award determines that such breach has occurred and, if such breach is a failure to pay amounts due under this Agreement which payment is disputed in good faith by the breaching
Party, this Agreement shall not terminate pursuant to this Section 13.4 based on such payment breach if the breaching Party pays the amounts finally determined to be due, with interest calculated in the manner set forth in Section 7.6, if
applicable, within [* * *] after the final arbitration award is rendered. 
 13.5 Termination for Patent Challenge. In the event that
Alpharma or any of its Affiliates or Sublicensees commences or otherwise pursues, directly or indirectly (or voluntarily assists Third Parties to do so, other than as required by law or legal process), any proceeding seeking to have any of the
Product Patent Rights, [* * *] revoked or declared invalid, unpatentable, or unenforceable, Durect may as its sole remedy terminate this Agreement upon written notice to Alpharma. 
 13.6 Termination for Bankruptcy. Either Party may immediately terminate this Agreement upon the occurrence of either of the following:
(a) the entry of a decree or order for relief by a court having jurisdiction in the premises in respect of the other Party in an involuntary case under any applicable national, federal, or state insolvency or other similar law, and the
continuance of any such decree or order unstayed and in effect for a period of [* * *]; or (b) the filing by the other Party of a petition for relief under any applicable national, federal, or state insolvency or other similar law.

 13.7 Effect of Termination. 
 In the event of termination of this Agreement or in the event Durect terminates Alpharma’s license in any Terminated Country in accordance with
Section 4.2(c) or 4.3(d): 
 (a) all licenses granted by Durect to Alpharma in Section 3 shall terminate in the Territory or
Terminated Country, as applicable; 
 (b) in the Territory or Terminated Country, as applicable, Alpharma shall or shall cause its Affiliates
and Sublicensees, if any, to assign or transfer to Durect, at no Cost (except as otherwise specifically provided in Section 13.7(e) below and except that, to the extent any such assignment or transfer to Durect requires more than [* * *] of
effort by Alpharma, its Affiliates and/or Sublicensees, Durect shall reimburse Alpharma, its Affiliates and/or Sublicensees for any such efforts in excess of [* * *] hours on the same basis that Alpharma reimburses Durect for Durect Development
Costs hereunder), all Regulatory Documentation, Development Data, Regulatory Approvals, Product Trademarks (and goodwill associated therewith) Controlled by Alpharma or its Affiliates and Sublicensees, if any, as applicable, that relate to the
development, manufacturing, use or sale of the Product (collectively, the “Product Material); 
 (c) if applicable, subject to
Section 13.3(b), Alpharma shall continue during the notice period before termination becomes effective (or if reasonably practicable and agreed to by Alpharma at such time, allow Durect or its Clinical research organizations
(“CROs”) to continue any ongoing Clinical Trial for which Alpharma has responsibility; and 
 (d) if Alpharma has
manufactured, or has had manufactured the Product for Clinical Trial or Commercialization, Alpharma at its option shall either transition the manufacturing process to Durect or a mutually agreed Third Party CMO or supply the Product to Durect;

 In the event that they shall be unable to resolve the Dispute by consensus within such [* * *] period, then the
Dispute shall be finally settled by binding arbitration as provided below. 
 (b) Except as expressly otherwise provided in this Agreement,
any dispute arising out of or relating to the interpretation of any provisions of this Agreement or the failure of either Party to perform or comply with any obligation of such Party pursuant to this Agreement or the breach, termination or validity
hereof (a “Dispute”), shall be exclusively and finally settled by arbitration under the Commercial Arbitration rules of the American Arbitration Association (“AAA”) then in effect (the “Rules”), as
modified by the terms set forth in this Section 14.12(b). The place of arbitration of any Dispute shall be in New York, New York. Such arbitration shall be conducted by three arbitrators, one appointed by each of Alpharma and Durect and the
third selected by the party-appointed arbitrators. Each arbitrator shall be neutral and impartial and shall have relevant experience in the pharmaceutical industry. Alpharma and Durect shall make their respective appointments within [* * *] of
receipt by the respondent of a copy of the demand for arbitration. Such party-appointed arbitrators shall select the third arbitrator within [* * *] of the appointment of the second arbitrator. If any arbitrator is not timely appointed, on the
request of any Party such arbitrator shall be appointed by the AAA in accordance with the listing, striking and ranking provisions in the Rules. The arbitrators shall render an award as expeditiously as possible; if practicable, within six months
after the appointment of the third arbitrator. Any award rendered by the arbitrators shall be final and binding upon the Parties. Judgment upon any award rendered may be entered in any court having jurisdiction, or application may be made to such
court for a judicial acceptance of the award and an order of enforcement, as the case may be. Except as provided in Section 12.5, each Party shall pay its own Costs of arbitration, provided, however, the fees and expenses of the arbitrators
shall be equally shared between Alpharma and Durect. Any Costs (including attorney’s fees and expenses) incident to enforcing the award shall be charged against the Party resisting such enforcement. This Section 14.12 shall not prohibit a
Party from seeking preliminary injunctive relief in aid of arbitration from a court of competent jurisdiction in the event of a breach or prospective breach of this Agreement by any other Party which would cause irreparable harm to the Party seeking
such relief. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitrators

shall have full authority to grant provisional remedies and to direct the Parties to request that any court modify or vacate any temporary or preliminary
relief issued by such court, and to award damages for the failure of any Party to respect the arbitrators’ orders to that effect. 
 14.13 Compliance with Laws. Each Party shall review in good faith and cooperate in taking actions to ensure compliance of this Agreement and the Parties’ activities hereunder with all Applicable Laws. Each Party shall provide
the other Party such reasonable assistance as may be required for the Party requesting such assistance to comply with all Applicable Laws necessary to permit the Parties to perform hereunder and to exercise their respective rights hereunder.

 14.14 Force Majeure. Except where expressly provided for herein, neither Party shall be held liable or responsible to the other
Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation of this Agreement to the extent that such failure or delay is due to Force Majeure, and
without the willful wrongdoing, recklessness or gross negligence of the Party so failing or delaying. For purposes of this Agreement, “Force Majeure” is defined as causes beyond the reasonable control of the Party, including acts of
God; changes in regulations or laws of any government; war; terrorism; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of public utilities
or common carriers. In the event that the ability of Durect or Alpharma to perform its obligations under this Agreement, as the case may be, shall be so affected, the affected Party shall immediately notify the other Party of such inability and of
the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled and the
[* * *] thereafter. To the extent possible, each Party shall use Commercially Reasonable Efforts to minimize the duration of any Force Majeure. 
 14.15 Entire Agreement. This Agreement including schedules and exhibits thereto, including the Development Plan together with all other future written agreements entered into by the Parties and specifically made a part of this
Agreement, constitute the entire agreement between the Parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both oral and written, between the Parties with respect to the subject matter
of this Agreement.
