3.6. Right of [* * *] Regarding [* * *]. Commencing at any time upon [* * *] establishment of a development program for a [* * *], if any, if [* * *] desires to seek a Third Party to collaborate in the development and/or Commercialization of such [* * *] or if [* * *] elects to Commercialize such [* * *], it shall provide written notice thereof (“First Refusal Notice”) to [* * *] and provide information reasonably requested by [* * *] regarding such [* * *]. Upon receipt of a First Refusal Notice, [* * *] shall have [* * *] to (i) notify [* * *] in writing if it desires to participate with [* * *] in the further development and/or Commercialization of the [* * *] or (ii) decline to bid. If [* * *] does not respond in writing to the First Refusal Notice or notifies [* * *] that it declines to bid within such [* * *] period, then it shall no longer have any rights with respect to the [* * *]. If [* * *] provides [* * *] with timely notice of its interest in participating in the development and Commercialization of such [* * *], then the Parties shall attempt in good faith to negotiate the terms of an agreement for [* * *] to participate with [* * *] in the development or Commercialization of the [* * *] for a period of [* * *] (which may be extended upon written agreement of the Parties) (“Negotiation Period”). If, despite such good faith negotiations, [* * *] are unable to enter into a definitive agreement during such Negotiation Period, then [* * *] will thereafter be free to develop or Commercialize such [* * *] itself or enter into agreement(s) with Third Parties for the development and Commercialization of such [* * *]; provided that if thereafter [* * *] intends to license

Commercialization rights to such [* * *] to a Third Party more than [* * *] after the end of the last Negotiation Period with respect to such [* * *] or intends to license Commercialization rights to such [* * *] to a Third Party on terms and conditions more favorable to the Third Party when all such terms and conditions are taken in the aggregate than those last offered to [* * *] shall first re-offer such opportunity to [* * *] by delivering a new First Refusal Notice to [* * *] and provide to [* * *] any updated information reasonably requested by [* * *] regarding such [* * *], in which case the second, third, fourth and fifth sentence of this Section 3.6 shall apply to such new First Refusal Notice.

4.1 Development 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.

(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.

(e) Except as otherwise set forth in Section 4.3(a), if any dispute arises between the Parties regarding the matters set forth in Section 4.3, then such matter shall be submitted for resolution in accordance with Section 14.12.

(a) Prior to the first Regulatory Approval of the Product, Alpharma will provide to Durect draft forms of protocols for all studies required for seeking a label indication in Subterritory A and the Major Market Jurisdictions. Alpharma shall consider in good faith all comments provided by Durect in writing within the [* * *] period following Durect’s receipt of such protocols; provided that Alpharma shall have the sole discretion and authority to make all decisions with respect to final protocols and all other matters relating to development of the Product. Alpharma shall promptly provide Durect with a copy of all final reports and final protocols from Preclinical and Non-Clinical trials and Clinical Trials in Subterritory A and the Major Market Jurisdictions.

(b) Promptly following, and in any event not later than [* * *] following, the Effective Date, Durect shall (i) transfer and assign to Alpharma ownership of all INDs held by Durect for the Product in the Territory, if any, including copies of any Regulatory Documentation regarding the Product in the Territory and (ii) transfer and assign to Alpharma,

In addition, promptly following the Effective Date, Durect shall transfer to Alpharma copies of all Development Data in existence as of the Effective Date. After such transfers and assignments by Durect, Alpharma shall be responsible for all Product-related reporting and other obligations to any Regulatory Authorities.

(c) During the period that the JDC remains in existence, all significant Product-related regulatory decisions within the Subterritory A and the Major Market Jurisdictions shall be subject to review of the JDC. Durect shall have the right to review and comment upon material portions of regulatory filings and correspondence regarding major or material issues proposed to be made or sent with respect to the Product in Subterritory A and the Major Market Jurisdictions prior to their submission to Regulatory Authorities, provided that (i) such review opportunity may be provided by electronic access to drafts of such documents, (ii) the Alliance Managers will (with oversight from the JDC) coordinate the scope, timing and form of such document access in a manner that seeks to minimize administrative burden and (iii) for any comments from Durect to be considered, 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 receipt of Regulatory Approval to market the Product in any Jurisdiction within [* * *] after receipt of any such approval.

4.5 Line Extensions. In the event that Alpharma desires to develop Line Extensions to the Product which Alpharma deems beneficial to the Commercialization of the Product in the Territory, Alpharma shall deliver to the JEC a written proposal summarizing the proposed Line Extension together with a plan summarizing the activities necessary to develop the Line Extension through Regulatory Approval in the Territory similar to the approach outlined in the Development Plan. Upon receipt of such documentation, the JEC shall meet to discuss and consider such proposed Line Extension and approve any plans and budgets for any Durect Development Responsibilities. The Line Extension shall be encompassed in the definition of “Product” under the Agreement, and subject to all the terms and conditions applicable thereto under this Agreement.

(a) Notwithstanding anything herein to the contrary, the following activities with respect to Product development are allocated to Durect (collectively “Durect Development Responsibilities”): (i) unless otherwise agreed upon by the Parties, all development activities through completion of Phase 2 [* * *]; (ii) Dosage Form Development; (iii) manufacturing and analytical method development, validation, stability and other CMC-related activities; (iv) management of any and all technology transfer, scale-up to commercial batch size and validation activities that may be required to enable any Person chosen by Alpharma to manufacture commercial supplies of the Product; (v) generation of necessary documents related to the Durect Development Responsibilities in order for Alpharma to perform Clinical Trials and file for Regulatory Approval in the Territory; and (vi) any other development activity allocated to Durect by Alpharma and agreed to by Durect.

Patent Royalties shall begin to accrue in accordance with the charts set forth below, on a Jurisdiction-by-Jurisdiction basis, on Net Sales within the Territory during the period commencing on the date of the First Commercial Sale of the Product in such Jurisdiction and shall be payable until, the later of the expiration of (i) all Patents containing one or more Valid Claims that would be infringed by the development, manufacture, sale, offer for sale, use, importation or exportation of the Product, or (ii) Marketing Exclusivity

Rights in such Jurisdiction (such period the “Patent Royalty Term”). Notwithstanding the foregoing however, if, during a given calendar quarter during the Patent Royalty Term, there is a Generic Product commercially sold by a Third Party in a Jurisdiction, then so long as such Generic Product is being sold by such Third Party, the Royalties due with respect to Net Sales in such Jurisdiction for such quarter during the Patent Royalty Term shall be reduced by [* * *] percent ([* * *]%) of the rates set forth in the charts below in this Section 6.2(a).

For Sales in Subterritory B, Subterritory C and Subterritory D in the aggregate

The Royalty rates set forth above shall apply only to that portion of Net Sales within the applicable tier of Net Sales.

The periods by which annual Net Sales are measured for purposes of this Section 6.2 shall be a calendar year (each, an “Annual Net Sales Period”) except that the first Annual Net Sales Period shall begin on the first day of the calendar quarter preceding the First Commercial Sale and continue to the end of the calendar quarter ending on December 31^st of that calendar year. For purposes of illustration, see Example 1 in Schedule 6.2.

(b) Know-How Royalties. Know-How Royalties shall accrue, on a Jurisdiction-by-Jurisdiction basis, on Net Sales in the Jurisdiction during any portion of the applicable Royalty Term that remains after the expiration of the applicable Patent Royalty Term (the “Know-How Royalty Term”). Subject to the other provisions of this Section 6, if the Know-How Royalty Term is in effect in a Jurisdiction, Alpharma shall pay Durect Know-How Royalties with respect to the aggregate annual Net Sales in such Jurisdiction at a rate of [* * *]% of the rates set forth in the tables set forth in Section 6.2(a). The first Annual Net Sales Period in which Know-How Royalties are payable shall begin on the first day of the Know-How Royalty Term and continue to the end of the calendar quarter ending on December 31^st of that calendar year. For purposes of illustration, see Example 2 in Schedule 6.2.

6.3 Sublicense Income. In addition to the Royalties payable to Durect under Section 6.2 and the One-Time Payments payable to Durect under Section 6.1, if Alpharma grants a Sublicense under Section 3.2 with respect to a Jurisdiction, Alpharma shall thereafter pay Durect, within [* * *] after the receipt thereof by Alpharma, [* * *] percent ([* * *]%) of the portion of any Sublicense Fees received by Alpharma that exceeds the aggregate of all One-Time Payments payable by Alpharma to Durect with respect to such Jurisdiction.

6.4 Existing Third Party Royalties. Durect shall be solely responsible for payment of [* * *] percent ([* * *]%) of all financial obligations to [* * *] under the [* * *] Agreement.

7.1 Payments of Royalties. Beginning [* * *] after the end of the calendar quarter in which the First Commercial Sale is made and for each calendar quarter thereafter (no later than [* * *] after the end of such calendar quarter), Alpharma shall submit a statement to Durect, which shall set forth the amount of Net Sales in the Territory by Jurisdiction, during such quarter, and the calculation of Royalties due on such Net Sales in each Jurisdiction and in the aggregate for the Territory for such quarter. Each such statement shall be accompanied by the payment, if any, due to Durect.

7.2 Mode of Payment for One-Time Payments and Royalties. Alpharma shall make all payments required under this Agreement by wire transfer to any account specified by Durect or as otherwise directed by Durect from time to time in Dollars.

7.3 Currency Conversion. Royalties with respect to any Net Sales in Jurisdictions where the Dollar is not used as currency shall be calculated by converting the amount of Net Sales into the corresponding amount in Dollars and applying the applicable Royalties percentage under Section 6 to such amount. The currency conversion shall be made using the average of the rates of exchange for 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 calendar year in which such sales or costs were occurred, and in sufficient detail to permit the Parties to confirm the accuracy of each of the foregoing.

7.5 Audit Request. During the Term of this Agreement and for a period of [* * *] thereafter, at the request and Cost of a Party (the “Auditing Party”), Durect and its Affiliates (in the case of a request by Alpharma) or Alpharma and its Affiliates and Sublicensees (in the case of a request by Durect) (the “Audited Party”) shall permit an independent, certified public accountant appointed by the Auditing Party and reasonably acceptable to the Audited Party, at reasonable times and upon reasonable advance notice of not less than [* * *], but not more often than [* * *] in each calendar year, to examine such records during the [* * *] prior to the notice as may be necessary to determine the correctness of any report or payment made under this Agreement or obtain information as to the determination of the Durect Development Costs, Net Sales and Royalties payable for any calendar quarter in such audited period. Results of any such examination shall be made available to all Parties except that said independent, certified public 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.

7.7 No Non-Monetary Consideration for Sale. Alpharma and its Sublicensees and Affiliates shall not accept or solicit any non-monetary consideration for the sale of the Product without the prior written consent of Durect, provided, however, the use by Alpharma and its Affiliates of a customary and reasonable amount of the Product for promotional sampling, compassionate use or donations shall not violate this Section 7.7.

8.1 Responsibility. Alpharma shall use Commercially Reasonable Efforts, at its sole Cost, to manufacture the Product for Clinical use and Commercialization in the Territory in compliance with the terms and conditions of this Agreement. At Alpharma’s election, Durect shall assign the [* * *] Agreement to Alpharma within [* * *] of the Effective Date.

8.2 Technology Transfer. In the event that Alpharma elects to have Product manufactured by itself or a CMO other than [* * *], Durect shall use Commercially Reasonable Efforts to provide in a timely manner such of Manufacturing Technology Controlled by Durect in order for Alpharma or the CMO selected by Alpharma to manufacture the Product, and shall use Commercially Reasonable Efforts to provide technical assistance to enable the use of such Manufacturing Technology to manufacture the Product, such assistance to be detailed in a technology transfer plan to be agreed upon by the Parties (the “Technology Transfer Plan”). Alpharma shall reimburse Durect its Durect Development Costs incurred in providing the Manufacturing Technology and technical assistance in accordance with a budget therefor to be agreed by the Parties in advance. Durect shall be reimbursed by Alpharma on a monthly basis, within [* * *] of receipt of an invoice setting forth such Durect Development Costs.

8.3 Commercial Supply in Territory. Alpharma shall have sole responsibility (including complete decision making authority and discretion) to manufacture or have manufactured Product for the Commercialization of the Product in the Territory, and shall use Commercially Reasonable Efforts to maintain or arrange for sufficient manufacturing capacity to meet the reasonably anticipated market demand for the Product in the Territory.

9.1 Ownership of Collaboration Inventions. Subject to the terms hereof, including the licenses and other rights granted hereunder, all Collaboration Inventions shall be owned as follows:

(a) [* * *] Collaboration Inventions (including all Patents and other Intellectual Property Rights relating thereto) that relate to the Product (including, inter alia, components thereof, its composition or formulation, methods of manufacture, processing, finishing, packaging and methods of use), without regard to inventorship (each such Collaboration Invention a “Product Collaboration Invention”).

(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.

(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.

(c) Alpharma Patents. As between Durect and Alpharma, Alpharma may prepare, prosecute and 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.

(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 [* * *] before the expiration of the period

within which a patent holder may bring an action for infringement against such Third Party. Durect shall then have the right, but not the duty, to institute 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.

(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 [* * *];

(ii) if Durect has instituted and maintained such action alone, Durect shall be 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.

(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.

(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 in a manner that would adversely affect the rights granted by Durect to Alpharma under this Agreement; and (b) without the prior written consent of Alpharma, shall not amend or terminate or allow to lapse (except for the natural expiration of the [* * *] Agreement in accordance with its terms) the [* * *] Agreement or [* * *] Agreement, if such amendment, termination or lapse would adversely affect the rights granted by Durect to Alpharma under this Agreement. Alpharma acknowledges that its sublicense to the [* * *] is subject to the applicable terms of the [* * *] Agreement. In addition, notwithstanding the foregoing, Durect shall not be deemed in breach of this Section 9.10 if such breach, default or termination of the [* * *] Agreement is due to Alpharma’s failure to comply with the terms of the [* * *] Agreement which are applicable to Alpharma and have been fully disclosed to Alpharma prior to the Execution Date. [* * *].

10.1 Notification. The Parties recognize that each may wish to publish the results of their work relating to the subject matter of this Agreement. However, the Parties also recognize the importance of acquiring patent protection and other considerations. Consequently, subject to any Applicable Laws obligating any Party to do otherwise, any proposed publication by any

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.

10.4 Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise 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 the public or was otherwise part of the public domain after its disclosure and other

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.

10.5 Exceptions to Obligation. The restrictions contained in Section 10.4 shall not apply to Confidential Information that: (i) is submitted by the recipient to a Regulatory Authority to obtain Regulatory Approval for the Product; (ii) is provided by the recipient to Third Parties under confidentiality provisions at least as stringent as those in this Agreement, in connection with 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.

Each Party shall be entitled, in addition to any other right or remedy it may have, at law or in equity, to seek an injunction, without the posting of any bond or other security, enjoining or restraining the other Party, its Affiliates and/or its licensees from any violation or threatened violation of this Section 10.

(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.

(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 [* * *],

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.

This Agreement, to the extent signed and delivered by means of a facsimile machine (or pdf-file attachment to Email), shall be treated in all manner and respects and for all purposes as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.

14.9 Severability. When possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.

14.11 Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of New York without regard to conflicts of law principles.

(a) The Parties recognize that a bona fide dispute as to certain matters may from time to time arise during the Term of this Agreement that relate to any Party’s rights or obligations hereunder. In the event of the occurrence of any Dispute (as defined below), either Party may, by written notice to the other, have such Dispute referred to its highest ranking officer for attempted resolution by good faith negotiations within [* * *] after such notice is received. If either Party desires to pursue arbitration under paragraph (b) below to resolve any such Dispute, unless expressly provided for otherwise herein, a referral to such executives under this paragraph (a) shall be a mandatory condition precedent. Said designated officers as of the Effective Date are as follows.

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.

14.16 Parties in Interest. All of the terms and provisions of this Agreement shall be binding upon, inure to the benefit of and be enforceable by the Parties hereto and their respective permitted successors and assigns.

14.17 No Third Party Beneficiaries. Except for rights and obligations specifically referred to herein that apply to Affiliates, sublicenses or licensees of the Parties, nothing in this Agreement is intended to confer on any Person other than Durect or Alpharma any rights or obligations under this Agreement, and there are no intended Third Party beneficiaries to this Agreement.

14.18 Descriptive Headings; Certain Terms. The descriptive headings of this Agreement are for convenience only, and shall be of no force or effect in construing or interpreting any of the provisions of this Agreement.

14.19 Fees and Payments. All fees and payments made by one Party to the other under this Agreement shall be deemed non-refundable unless expressly provided to the contrary herein.

14.20 No Implied Licenses. Except as specifically and expressly granted in this Agreement, no rights or licenses to any intellectual property rights are granted by either Party to the other, by implication, estoppel or otherwise, and each Party specifically reserves all its rights with respect to any intellectual property rights not specifically granted hereunder. Furthermore, unless expressly provided otherwise herein, each Party may use and practice its own Intellectual Property Rights, technology and data in any manner not inconsistent with the terms of this Agreement without the consent of the other Party and without obligation to notify the other Party of its intended use.

14.21 Information for Financial Reporting. In addition to the reports provided by Alpharma pursuant to Section 7.1, Alpharma agrees to provide to Durect good faith non-binding estimates of Net Sales and other information reasonably necessary for Durect to estimate the Royalties in each calendar month following the commercial launch of the Product within ten (10) days after the end of such month. Alpharma shall not have any liability for any inaccuracy in any such report. Each such report shall constitute Confidential Information of Alpharma and

shall not be disclosed by Durect to any Third Party other than to Durect’s accountants and auditors in confidence, except for any disclosures as may be required to be made by Durect in order to comply with applicable law, regulations, court order, or tax or securities filings.
