All inventions developed by the Parties under this Agreement solely relating to LTS’s existing TTS technology, including but not limited to [***] of TTS, shall be the property of LTS (“LTS IP”). [***]. NeurogesX hereby irrevocably assigns, and agrees to assign to LTS any right, title and interest it may have in and to the LTS IP, and shall assist LTS, upon reasonable request and at LTS’s sole expense, to secure or perfect any and all such rights.

(b) NeurogesX Owned. All inventions developed by the Parties under this Agreement [***] uses of VRl-Ligands shall be the property of NeurogesX (“NeurogesX IP”). LTS hereby irrevocably assigns, and agrees to assign to NeurogesX all of its right, title and interest in and to NeurogesX IP, and shall assist NeurogesX, upon reasonable request and at NeurogesX’s sole expense, to secure or perfect any and all such rights.

(c) Jointly Owned. [***] inventions developed by the Parties under this Agreement shall be the joint property of the Parties (“Joint IP”), provided that it does not belong to [***]. Neither Party shall have any obligation to account to the other Party for profits with respect to, or to obtain any approval of the other Party to license or exploit, any Joint IP by reason of their joint ownership, and each Party waives any such right it might have under the applicable laws in any country; provided, that NeurogesX [***] have the right to [***] applications and products.

8.2 Prosecution of Patents Covering the Patch.

(a) As used in this Sections 8.2 and 8.4, “prosecute” means the procedure(s) involved in securing patent rights in patent offices worldwide.

(b) LTS shall have the right, but not the obligation, to file, prosecute and/or maintain any patent or patent application solely owned by LTS covering the Patches.

(c) If LTS elects to file, prosecute and maintain any such patent or patent application, the expenses of such action shall be borne by LTS.

(d) If LTS elects not to file, prosecute or maintain any such patent or patent application in any jurisdiction, it shall notify NeurogesX at least [***] prior to the due date for action or payment. NeurogesX shall then have the right, to file, prosecute and/or maintain any such patent or patent application.

*** Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions.

-13-

(e) If NeurogesX elects to file, prosecute and maintain any such patent or patent application in such jurisdiction, the expenses of such action shall be borne by NeurogesX, and NeurogesX shall have a non-exclusive (except as set forth in this Section 8.2(e)), transferable, sublicensable, royalty free, perpetual license under such patents or patent applications to make, use, sell, offer for sale, export, practice and otherwise exploit the subject matter thereof. The foregoing license shall be exclusive for the Field. NeurogesX shall have the first right to enforce such patents and patent applications in the Field and retain all revenues therefrom, notwithstanding Section 8.3 below.

8.3 Third Party Infringement in the Field. Each Party agrees to promptly notify the other Party if it becomes aware of any third party’s TTS in the Field that infringes LTS’s patents covering the Patch (an “Infringement”). LTS shall have the first right, but not the obligation, to enforce its patents against any Infringement. LTS shall solely control any such enforcement action. LTS shall keep NeurogesX informed of the proceeding of such enforcement. In case NeurogesX believes LTS is not diligently pursuing the enforcement, NeurogesX shall have the right to consult with LTS. LTS agrees not to settle or otherwise terminate or delay its enforcement against any Infringement in a manner which would permit the third party to continue manufacturing and/or selling infringing TTS in the Field in contravention of the exclusivity granted to NeurogesX under Section 6.2 or Article 7 of this Agreement or the Supply Agreement. LTS shall not settle any Infringement action without the prior written approval of NeurogesX. In the event LTS notifies NeurogesX within 120 days after notice of an alleged Infringement by either party that it intends not to file suit against any alleged Infringement, or does not give any notification whether it intends to file suit within one hundred and twenty (120) days after notice of an alleged Infringement by either party or drops any action against an alleged Infringement, then NeurogesX shall have the right, but not the obligation, to enforce LTS’s patents covering the Patch against such alleged Infringement. LTS agrees to use Reasonable Commercial Efforts to assist and cooperate with NeurogesX in any enforcement by NeurogesX under this Section 8.3, at NeurogesX’s cost and expense. If LTS decides to enforce its patents against Infringement and NeurogesX permits LTS to claim NeurogesX damages, then any proceeds recovered from any such Infringement action shall be divided [***] between NeurogesX and LTS after first subtracting all legal and attorney fees and expenses. In the event NeurogesX is given the right to enforce LTS’s patents against Infringement and LTS permits NGX to claim LTS’s damages, then again any proceeds recovered from any such Infringement action shall be divided [***] between NeurogesX and LTS after first subtracting all legal and attorney fees and expenses.

8.4 Cooperation. Each Party shall cooperate with the other Party at the other Party’s expense to execute all lawful papers and instruments, to make all rightful oaths and declarations, and to otherwise assist the other Party including without limitation participating in enforcement actions, as may be necessary and reasonably requested in the preparation and prosecution of any or all patents and patents applications regarding the Patches, and the enforcement thereof.

8.5 IP Review by LTS. LTS shall review on a regular basis the intellectual property rights relevant for LTS’s work LTS shall give NeurogesX a confirmation in writing [***] a year (on or about [***] of each year) that, to the best of its actual knowledge, [***] with respect to the Patches.

Each party warrants and represents to the other party that it has not previously granted and will not grant any rights in conflict with the rights granted herein.

9.2 Clinical Samples. Subject to the limited liability provisions set forth in this Agreement, LTS represents and warrants that the Clinical Samples delivered to NeurogesX shall be in conformity with the Specifications, shall be manufactured in accordance with Current GMP and the Quality Assurance Agreement, and shall comply with all Regulatory Requirements.

(a) Rejection of Defective Clinical Samples. NeurogesX may reject Defective Clinical Samples (subject to NeurogesX providing sufficient evidence of appropriate and correct storage at all times according to the storage conditions set forth in the applicable Specifications) by delivering to LTS written notice of rejection, and if practical, specifying the nature of the Defect and the Clinical Samples lot number, within [***] days after receipt by NeurogesX of the applicable shipment. In the case of Clinical Samples with Defects that are not reasonably discoverable upon NeurogesX’s customary incoming quality control testing (“Latent Defects”), NeurogesX may reject such Clinical Samples within [***] days after discovery of the Latent Defects.

(b) Replacement of Defective Clinical Samples. During the [***] period commencing on the date the Clinical Samples are delivered to NeurogesX, LTS shall promptly (and in any event within [***] of receipt of notice of rejection) deliver to NeurogesX, at LTS’s own cost and risk, including shipping costs, replacements for any rejected Defective Clinical Samples, up to the maximum of units contained in the applicable lot; but provided that NeurogesX can prove by sufficient evidence mat such Defect is not due to the mishandling or incorrect or inappropriate storage (i.e., not in accordance with the Specifications) of the Clinical Samples by NeurogesX and or any third party who has had access thereto.

LTS shall have the right to examine any Clinical Samples rejected by NeurogesX, provided such examination shall not delay the shipping of replacement Clinical Samples. In the case LTS disagrees that the rejected Clinical Samples are subject to this Section 9.2, the claim may be submitted for tests and a decision by a mutually agreed upon, independent and reputable third party laboratory in the United States, which appointment shall not be unreasonably withheld or delayed by either Party. The determination of such laboratory shall be final and binding upon the Parties. The Party against whom the determination is made shall be responsible for the fees and expenses of such determination, as well as the costs of the replacements for the rejected Clinical Samples at issue, including shipping costs.

Section III

Description of Functions and Responsibilities

Production of product

LTS shall manufacture and test NGX’s drug product in accordance with LTS’s SOPs, cGMPs, applicable laws and regulations, including all applicable FDA regulations, any applicable local laws and regulations in the place of manufacture, and any IND, NDA, MAA and other regulatory filings or approvals for the drug product (collectively, the “Regulatory Requirements”), and applicable contracts between LTS and NGX, including the parties’ Memorandum Of Understanding, as amended on May 29, 2002. The manufactured product shall adhere to the specification supplied by NGX or as mutually agreed upon and in compliance with all cGMPs and any other applicable Regulatory Requirements. LTS will prepare for each batch of product manufactured for NGX, the complete production record documentation (see section IV, Batch Accompanying Documentation). This completed documentation will be retained by LTS in accordance with its document retention policy and Regulatory Requirements, and in no event less than 10 years. The documentation will be readily accessible for review and inspection by NGX and regulatory authorities, and true copies of these records will be sent to NGX by LTS for each batch of product produced.

Control of Suppliers

LTS shall maintain an approved supplier’s list in accordance with LTS’s procedures. NGX’s approval will be required for any supplier change for materials used in NGX’s products. LTS shall notify NGX of intended change in suppliers at least 6 months in advance of implementing the change. LTS will provide the Material Name, Supplier Name and Manufacturing Location to NGX upon request. The initial approved supplier’s list shall be subject to NGX’s written approval.

Third Party Service Providers

Should LTS employ a third party service provider (TPSP) for any manufacture, testing or performance of any ancillary function related to NGX’s product, NGX and LTS and the TPSP will agree on the following:

1. LTS will not use any TPSP without a written consent by NGX.

2. LTS will be the primary contact with the TPSP.

3. LTS will adequately qualify the supplier according to LTS policies and procedures and this Quality Assurance Agreement.

4. LTS will be responsible for release and review of any one part or all parts of the process performed by TPSP, and shall be responsible for any actions performed by the TPSP with respect to NGX’s product as if performed by LTS itself.

5. LTS will perform appropriate process transfer according to their internal procedures and applicable regulations.

-5-

6. NGX retains the right to review or obtain copies of documents created by TPSPs and retained by LTS.

7. The Quality Assurance Agreement with TSPS shall not have discrepancies to this Quality Assurance Agreement or other agreements between LTS and NGX.

8. NGX will not give analytical methods or procedures of LTS to TSPS without written consent of LTS.

Printed Materials

NGX will be responsible for, and provide LTS with, all copy content and artwork for all printed materials associated with the product, e.g. labels, etc. NGX will be responsible for compliance with all necessary laws and regulations concerning such materials. The products supplied to NGX hereunder shall be packaged and labeled in accordance with instructions from NGX.

Drug Product Specifications

The referenced drug product(s) must be manufactured, packaged, labeled (if necessary) and handled according to the written specifications and procedures as outlined in this agreement. Changes to the specifications shall be mutually agreed upon and approved by both parties.

In testing drug product(s) NGX and LTS will agree upon the analytical methods requiring validation. For those methods which appear in the current compendia or other recognized standard references, a statement indicating the reference shall suffice. For those analytical methods developed by LTS, documentation supporting the validation of the analytical method shall be supplied upon request, to NGX.

Each lot of drug product will be sampled and tested in accordance with the agreed upon LTS procedures, cGMPs and must meet the specifications as outlined in this agreement.

Reserve samples

LTS shall keep retention samples of raw materials as required by LTS’s SOPs and Regulatory Requirements. LTS shall commit itself to keep reserve samples of drug product for regulatory purposes for each batch of drug product produced.

If batches are reworked and/or reprocessed additional retention samples will be collected and retained by LTS. The quantity of critical intermediate and drug product retained should be at least three times the amount to be able to perform all physical and chemical tests according to the Certificate of Analysis.

Deviations, OOS and Non-Conformances (Significant Events)

All deviations from approved, product–specific procedures or specifications, Out-Of-Specification test results of any kind, and any non–conformances to specifications will be considered Significant Events and will be investigated and resolved, as applicable, by LTS in consultation with

-6-

NGX, provided that such Significant Event occurs during the manufacture of NeurogesX product and have, to the best of the knowledge of LTS, the potential to substantially impact the NeurogesX product. Reprocessing or reworking of drug product or intermediates will always be considered a Significant Event. LTS must notify NGX within 5 working days of each Significant Event, and within within reasonable time of the completion and results of the investigation concerning such Significant Event. The documentation of the occurrence of the Significant Event, the investigation and any necessary actions required for resolution will be retained as part of the batch document for the batch(es) affected and a copy thereof provided to NGX. On mutual agreement additional and more in-depth investigation of the Significant Event will be performed by LTS. NGX shall review the documentation for each Significant Event and provide the required approval in writing for each Significant Event as soon as reasonably possible after the deviation has occurred, but in no event later than release of the relevant batch(es).

All actions investigating non-conformances and justifying the release of the batch of material must be fully documented to best of the knowledge of each party. The non-conformance documents relating to drug product or drug substance will be subject to approval by both LTS and NGX.

Release and Shipment of Product

LTS has the responsibility to release finished drug product to NGX. LTS will not ship any of NGX’s product to any destination other than NGX until NGX has released the product and authorized shipment or unless prior approval has been received from NGX to perform such shipments.

A Certificate of Analysis (CofA) or applicable documentation, as well as a Certificate of Production Compliance, shall be provided to NGX by LTS for each batch of drug product produced. The CofA, or equivalent, will be generated upon completion of all testing requirements and will contain the items tested, corresponding acceptance criteria, and test results. NGX is responsible for the approval and final release of all finished drug product after review of LTS’ CofA and other required documentation. Upon approval, NGX will notify LTS of such approval by forwarding to LTS the NGX completed and approved batch release checklist.

Reprocessing and Rework

Reprocessing and rework activity can only be performed per agreement between both LTS and NGX. Reprocessing and rework directions must be established to define the process. Reprocessing and/or rework of material or product must be documented to state reason and justification for processing. A reprocessing or rework Batch Record will be written and issued following standard procedures.

Change Control

All changes to this Quality Agreement must be documented as an addendum and reviewed and approved by authorized QAU representatives of LTS and NGX.

-7-

Changes to raw materials, packaging materials, equipment, utilities, facilities, manufacturing methods and procedures, product and material specifications and requirements, sampling, test methods, and release requirements will be implemented according the LTS’s change control procedures and, in cases of Significant Changes, will require NGX’s approvals. Changes to the approved Master Production Records and Final Product Specifications will always require LTS’s and NGX’s approvals.

LTS and NGX will jointly determine the most efficient route for handling change notifications. LTS will notify NGX of significant proposed changes at least 10 working days prior to the date of proposed implementation. LTS will not implement any changes without NGX’s written approval, which will be given or withheld by written notice within 5 working days after NGX receives LTS’s notice.

Audits and Inspections of Facilities and Products

LTS and TPSP’s will notify NGX (and in advance if possible) of any inspections or actions by regulatory agencies or other enforcement bodies in due time, of LTS’s or any TPSP’s facilities and/or processes which will directly impact NGX’s products. Where reasonably possible, LTS and TPSP’s shall afford NGX the opportunity to be present at such inspections.

NGX reserves the right to audit LTS’s facilities, systems, documents and processes (including validation, investigation and qualification processes) as they relate to the manufacture and control of NGX’s products or otherwise relating to LTS’s performance of this Agreement. These audits will be performed on an annual basis or as mutually agreed upon by LTS and NGX and at times convenient to NGX and LTS under such conditions as LTS may reasonable require in order to protect the confidentiality of it’s and other customer’s proprietary and confidential information.

NGX also reserves the right to audit TPSPs (e.g. contract laboratories, third party manufacturers, etc.) if utilized by LTS for NGX’s product. NGX reserves the right to be on site at LTS during manufacture of NGX’s products and/or during and regulatory inspection specific to NGX’s products with adequate notice to LTS. LTS will respond to, and forward all responses to observations, generated during NGX’s audit within 30 days of issuance.

Storage of Products

LTS agrees to store NGX’s products under appropriate product label storage conditions and in a secure area, to ensure they comply with all the quality specifications, attributes and in compliance with all applicable regulations. If special storage conditions are necessary for special purposes, the conditions, timeframes and material requirements will be supplied in writing by NGX.

Stability Activities

The responsibility for writing of stability protocols, stability testing, data interpretation and reporting will belong to LTS and will be conducted in accordance with ICH guidelines and in consultation with NGX. Stability protocols will be approved by NGX prior to initiation of the stability study. Stability protocols and reports will be subject to approval by NGX. Stability reports

-8-

will be provided to NGX by LTS at regular intervals and stability milestones. Updating of stability information to regulatory documents for the product is the responsibility of NGX. All stability related activities under the responsibility of LTS will be completed in a timely manner according to the agreed-upon stability protocols and applicable regulations. NGX will notify LTS to terminate stability programs at the end of clinical trial or when the lot on stability is no longer relevant.

Investigational Product Complaints

Each party shall provide any information regarding product complaints to the other party. LTS will assist NGX with any investigations required in regards to such complaints as a highest priority under this agreement. The results of the investigation will be documented in writing and be provided to NGX as soon as feasible in a timeframe to be agreed upon by LTS and NGX. NGX will communicate with the customers and/or regulatory authorities the results of the investigation, if necessary.
