---

orders for Patches submitted by NeurogesX and its designees after the First Forecast provided under Section 2.2 below shall be deemed orders for Patches
under this Agreement. To the extent LTS becomes aware that any Raw Materials or works-in-progress procured or made under this Agreement may be used to reduce the cost or price of units of Patches ordered under the Clinical Supply Agreement, LTS
shall notify NeurogesX and the Parties shall negotiate in good faith to so use such Raw Materials and works-in-progress and correspondingly reduce the price to NeurogesX of such units under the Clinical Supply Agreement. It is understood that this
Section 2.1(c) is not intended to prevent NeurogesX from using any supplies of Patches in its inventory that may have been purchased under this Agreement, for clinical trial purposes, provided however, that NeurogesX shall act in accordance
with all applicable laws and regulations.

2.2 First Forecast NeurogesX will provide LTS with a written forecast of the number of Patches
which will be required to be delivered during the first year following the first projected delivery hereunder (the First Forecast), at least [***] prior to the beginning of the Calendar Quarter in which the first delivery of Patches by
LTS is projected to occur. This First Forecast shall contain an estimate of the number of Patches required to be delivered, on a monthly basis, for such Calendar Quarter and the [***] three (3) Calendar Quarters. It is understood that only the
first Calendar Quarter of the First Forecast shall be binding on the Parties, and the subsequent Calendar Quarters in the First Forecast shall be non-binding for both Parties. NeurogesX agrees that the first Calendar Quarter in the first Rolling
Forecast (as defined below) shall specify the same quantities as specified in the first Calendar Quarter in the First Forecast.

2.3
Rolling Forecast. Each subsequent written forecast (each a Rolling Forecast) shall update the prior forecast, and will be provided by NeurogesX [***] prior to the beginning of each Calendar Quarter in which Patches are required to be
delivered. Each Rolling Forecast shall include an estimate of requirements on a monthly basis for such Calendar Quarter and the [***] three (3) Calendar Quarters, so that estimates for a rolling one (1) year period are always provided. The
Parties agree that only the first Calendar Quarter in each Rolling Forecast shall be binding on the Parties, as set forth in Section 2.4 below (quantities set forth in such first Calendar Quarter, the Binding Quantities). The
quantities forecasted for subsequent Calendar Quarters in such forecasts shall be non-binding for both Parties

2.4 Purchase Orders.

(a) Orders. NeurogesX shall place orders for quantities of Patches, on a [***] basis, [***] days before the month in which delivery of such
Patches is requested (the Delivery Month). For example, [***]. Each order shall specify the requested delivery date(s) within the Delivery Month, the shipping destination(s) and any shipping instructions. Unless otherwise agreed, the
quantities specified in each order shall be a [***] of the Batch Size. NeurogesX shall ensure that such orders, aggregated on a Calendar Quarter basis, specify a quantity of Patches to be delivered in such Calendar Quarter that is at least [***] of
the Binding Quantities for such Calendar Quarter. The Parties agree to use good faith efforts to establish the Batch Size by mutual written agreement after manufacture of the first [***] batches of Product based on actual batch sizes for production
hereunder; provided unfit such time the Batch Size for purposes of this Agreement shall be deemed to be the Theoretical Batch Size set forth in Exhibit A.

(b) Acceptance. LTS shall accept and fill all orders from NeurogesX for quantities of Product, subject to
the terms and conditions of this Agreement, provided that LTS shall not be obligated to accept orders to the extent the quantity for delivery in a particular Calendar Quarter exceeds [***] of the Binding Quantities for such Calendar Quarter. In
addition, the exact delivery dates within the Delivery Month shall be subject to acceptance by LTS, which acceptance shall not be unreasonably withheld. In the event LTS does not accept a delivery date requested by NeurogesX, the Parties shall
mutually agree to a delivery date which is as close as reasonable to the delivery date requested by NeurogesX (but not more than [***] weeks before or after the requested delivery date). Any objection to the delivery date or the quantities or other
aspects of an order must be submitted by LTS within [***] days of receipt of the order from NeurogesX, or such order shall be deemed fully accepted. After acceptance of an order, such order shall be deemed a Firm Order, and the accepted
or agreed delivery date, the Scheduled Delivery Date.

(c) Excess Quantities. LTS shall use [***] to accept and fill orders for
any quantities of Patches for delivery in a Calendar Quarter exceeding [***] of the Binding Quantities for such Calendar Quarter, on the requested delivery dates (Excess Orders). In the event LTS is unable to accept or fill any Excess
Orders despite using [***], LTS shall notify NeurogesX as soon as practicable, and such inability shall not be deemed a material breach of this Agreement entitling NeurogesX to terminate this Agreement nor a Failure Event under Section 6.4
below. LTS shall provide NeurogesX a Scheduled Delivery Date for Excess Orders within [***] days after receiving an Excess Order.

2.5
Packaging. Patches shall be shipped packaged in containers in accordance with the Quality Assurance Agreement, Exhibit E or as otherwise agreed by the Parties hereto in writing. Each such container shall be individually labeled with a description of
its contents, including the manufacturer lot number, quantity of Patches, and the date of manufacture.

2.6 Delivery. Subject to the terms
and conditions of this Agreement, including Section 2.8 below, LTS shall deliver quantities of Patches [***] on the Scheduled Delivery Dates. All Patches for delivery will be placed at the disposal of NeurogesX or its designee at the relevant

transportation and in compliance with any requirements set forth in the Quality Assurance Agreement. In the event NeurogesX has any special freight packaging or shipping instructions, it shall notify LTS and LTS will use [***] to comply with any
such instructions. All costs associated with such instructions shall be borne by [***]. [***] shall bear all costs of freight, shipping and insurance as well as indirect taxes, including import, customs, excise and sales taxes but not income taxes
related to the sale and purchase of Patches hereunder.

2.7 Refusal to Supply. LTS, after good faith consultation with NeurogesX for at least [***] days, may
refuse to supply Patches in a particular country, if LTS can reasonably demonstrate by evidence prepared or corroborated by an expert (recognized in the industry and having substantial experience in matters of public safety and toxicollogy) that the
proper sale, distribution and use of the Patch hereunder is likely to unreasonably endanger the public health.

2.8 Invoicing; Payment. LTS
shall submit an invoice to NeurogesX upon shipment of the Patches ordered by NeurogesX hereunder. All invoices shall be sent to the address specified in the purchase order, and each such invoice shall state the aggregate and unit Transfer Price for
Patches in a given shipment, plus any insurance, taxes or other costs incident to the purchase or shipment initially paid by LTS but to be borne by NeurogesX hereunder.

2.9 Late delivery. For purpose of this Agreement, delivery within [***] business days before or [***] business days after the Scheduled Delivery Date shall be deemed meeting such delivery date; provided that it is
understood LTS is only obligated to employ Reasonable Commercial Efforts to meet the requested delivery dates for Excess Orders. In the event that LTS does not deliver the ordered Patches within such a seven (7) business day window (i.e. [***]
days before or [***] days after), then NeurogesX shall, as its sole remedy for LTS being late with its delivery of Patches within the time periods set forth in clause (a) and (b) below, have the right to reduce its payment of the Transfer
Price for such Patches by: (a) [***] if NeurogesX receives the Patches between [***] days and [***] days after the Scheduled Delivery Date; or (b) [***] if NeurogesX receives the Patches later than [***] days after the Scheduled Delivery
Date. In the event NeurogesX does not receive the Patches within [***] days after the Scheduled Delivery Date, then in addition to reduction of payment of the Transfer Price set forth in clause (b) above, NeurogesX shall be entitled to deem
such delivery as having been ordered but never made, for purposes of determining a Failure to Supply under Section 6.4(a) below. For the purpose of this Section 2.9, a business day shall exclude a weekend day or a public
holiday in Germany or regional legal holiday at the Facility where the Patch is manufactured and those days where LTS is closed down in the regular course of business, e.g. between Christmas and New Year.

2.10 Correct Quantities. In the event LTS delivers at least [***] of the order and not more than [***], LTS shall be deemed to have delivered the ordered
quantities of Patches. It is understood that NeurogesX shall however only pay for the Patches it actually received, but not more than [***] of the applicable order, and only the actual number of Patches ordered and received shall be used to
determine whether or not LTS has supplied [***] as the case may be, of the Binding Quantities under Section 6.4(a)(i)(1) below.

2.11
Letter of Credit. In the event NeurogesX has not paid the Transfer Price for [***] shipment of Patches, which payment is not disputed by NeurogesX and is overdue for [***] or more days, and such failure to pay adds to a total amount of [***] or
more, then upon LTS reasonable request, NeurogesX shall cause to be delivered to LTS a confirmed letter of credit from an international bank (reasonably acceptable to LTS) at that point in time to secure its obligations hereunder to pay the
Transfer Price for any subsequent order of Patches, on terms and conditions reasonable and customary for such arrangements. NeurogesX shall maintain such letter of credit in effect until it has paid such outstanding overdue amount for the Transfer
Prices.

the delivery of artwork and text by NeurogesX (or its designee).

Any change to the artwork and text of the primary Patch packaging
reasonably requested by NeurogesX or its Sublicensees or required by any regulatory authority shall be communicated by NeurogesX to LTS in writing together with suitable samples of the revised artwork or text no later than [***] months prior to the
first delivery of Patches with such new primary Patch packaging. NeurogesX shall reimburse LTS for any packaging materials that can no longer be used as a result of any such change up to a maximum of [***] months inventory of such materials.
Provided that NeurogesX shall communicate such changes in the artwork and LTS has given its reasonable consent to such changes with a lead time of not less than [***] days, such changes shall not affect or modify the lead times for the supplies
pursuant to Section 2.4.

2.14 Raw Materials. All Raw Materials, other than the Active Ingredient, to be used in the manufacture of
the Patch shall be purchased by [***] at its own expense. LTS shall be responsible for testing and releasing all such Raw Materials in accordance with the Specifications, the Quality Assurance Agreement and all Regulatory Requirements.

In the event [***] orders or purchases appropriate quantities of Raw Materials in order to be able to supply the Patches as forecasted in the most
current [***] month period in the Rolling Forecast, as defined in Section 2.3, and has paid or has incurred a non-cancelable commitment to pay for such Raw Materials, and (A) [***] (i) cancels such orders pursuant to
Section 2.12; (ii) changes the forecasted quantities subject to the terms of this Agreement; or (iii) does not place orders in the amounts forecasted in such [***] month forecast; or (B) the Specifications or the artwork has

requested by NeurogesX, LTS may, instead of providing such parts of the Patch Regulatory Information to NeurogesX, elect to directly provide such parts of
the Patch Regulatory Information to the applicable regulatory authority in support of the regulatory filings of NeurogesX and its designees (and if so elected, will diligently do so), and will grant NeurogesX and its designees rights to reference
such filings made by LTS. Except as set forth in this Section 3.2 or otherwise required by law, LTS shall not correspond directly with the FDA or other health regulatory agencies relating to the process of obtaining Marketing Approvals or any
obtained Marketing Approvals for the Patch, without NeurogesXs permission. It is understood and agreed that the license of Section 7.1 of the Clinical Supply Agreement shall apply with respect to Patch Regulatory Information disclosed
under this Agreement, and that NeurogesX may disclose any and all Patch Regulatory Information to regulatory authorities in connection with obtaining and maintaining Marketing Approval for the Patches worldwide.

3.3 Support of Registration. If NeurogesX reasonably requests LTS to undertake such activities LTS shall use its [***] to support NeurogesXs
efforts to obtain and maintain Marketing Approvals for the Patch, provided, however, that NeurogesX shall pay for all labor costs of such activities at the then current man-hour rates of LTS and reimburse LTS for third party costs incurred with
respect thereto, in each case as requested by NeurogesX.

3.4 Changes.

(a) Specifications. Neither Party shall make any changes to the Specifications except as mutually agreed. If such changes result in a material change in
the Manufacturing Cost, the Parties shall agree on an appropriate adjustment to the Transfer Price of the Product hereunder covering at least the increased costs]. If such modifications result in a delay in delivery, the Parties shall negotiate a
reasonable extension of the affected lead times. Notwithstanding the foregoing, the Parties agree that they shall not withhold approval for any changes to the Specifications (i) requested by NeurogesX which are necessary to make them comply
with Regulatory Requirements in any country in which the Patches are being commercialized by NeurogesX, its Affiliates and/or Sublicensees or manufactured by LTS, or to address concerns regarding the toxicity, safety and/or efficacy of the Patch,
provided that NeurogesX agrees to pay LTS for the reasonable, documented, incremental labor and material costs incurred in connection with implementing such change, to the extent such costs are not covered by the mechanism for adjusting the Transfer
Price in Section 5.6, or (ii) requested by LTS as a result of events beyond its reasonable control (e.g. bankruptcy of its supplier), and such changes to Specifications as are necessary so that LTS can meet the Marketing Approval.

(b) Manufacturing Process. Unless otherwise required by applicable laws or regulations, LTS shall not, without the prior written consent
of NeurogesX, change any aspect of manufacture, including the facilities, equipment, processes, vendors, sub-contractors or record keeping procedures, in any manner (i) which to LTS [***] knowledge has the potential to [***] affect the
Patch, including any changes which may impact its safety or effectiveness, or (ii) which would delay or otherwise impact any filings for Marketing Approval for the Patch or would require an affirmative approval of the FDA, or any other health
regulatory authority in the Territory in which the Patch is being marketed, prior to its implementation. In the event NeurogesX requests a change or adjustment of any aspect of manufacture, including

the facilities, equipment, processes, vendors, sub-contractors or record keeping procedures and LTS agrees to implement such change or adjustment, or if such
change or adjustment is necessary, in case the annual requirements of the Patch can no longer be supplied according the current manufacturing process (including but not limited to facilities and equipment), however subject to the prior written
consent of NeurogesX as foreseen in the preceding sentence, NeurogesX shall pay LTS for the reasonable, documented, incremental labor and material costs incurred in connection with implementing such change, to the extent such costs are not covered
by the mechanism for adjusting the Transfer Price in Section 5.6.

(c) Territory. NeurogesX shall have the right to elect from time to
time to commercialize Patches in countries or regulatory jurisdictions outside the Territory upon written notice to LTS, with a reasonable lead time. In the event NeurogesXs decision to add any country or regulatory jurisdiction to the
Territory will cause LTS to (i) incur additional costs, as a result of specific Regulatory Requirements of such country or regulatory jurisdiction (Territory-specific Costs), and/or (ii) impose requirements beyond LTS
standard manufacturing practice, LTS shall in due time notify and discuss with NeurogesX such costs and such additional requirements. Upon such mutual agreement of the Territory-specific Costs and ways of accommodating such additional requirements,
NeurogesX shall have the option to either (1) modify or limit such addition to the Territory, or (2) include such countries or regulatory jurisdiction within the Territory and reimburse LTS for the Territory-specific Costs. It is
understood that LTS shall use [***] to mitigate any Territory-specific Costs and accommodate such reasonable requirements.

(d) Maximum
Capacity. NeurogesX shall update the Maximum Capacity - if necessary - to cover the whole term of the Agreement and shall have the right to elect from time to time to [***] the Maximum Capacity under this Agreement, upon written notice to LTS with a
reasonable lead time, provided, however, that any increase of the Maximum Capacity exceeding [***] Patches per year is subject to LTS prior written agreement, not to be unreasonably withheld.

3.5 Facility. All Patches supplied by LTS hereunder shall be manufactured at the Facility. The Facility (and any other facility that is involved in the
manufacture of Patches by or under authority of LTS) is and shall continue to be in compliance with cGMP and Regulatory Requirements and shall be available for governmental inspection if any competent governmental authority or governmental
organization so requests. LTS shall promptly provide to NeurogesX any cGMP certificate issued by any such competent governmental authority or organization.

3.6 Regulatory Issues. LTS will notify NeurogesX in due time (and no later than [***] days after LTS obtaining notice thereof) of any inspections, written notice of findings and/or actions by regulatory agencies or
other enforcement bodies of LTS facilities and/or processes which will directly affect the Patch or the manufacture thereof. Where reasonably possible, LTS shall afford NeurogesX the opportunity to be present at any such inspections. LTS shall
consult with NeurogesX in responding to any such inspections, written notice of findings and/or actions that directly affect the manufacture of the Patch, including by providing NeurogesX copies of any responses thereto for NeurogesXs review
and comment in advance of their submission to the regulatory agency, and using [***] to incorporate therein NeurogesXs comments as appropriate.

Affiliates and any sub-contractors and vendors of LTS with respect to the Patches, as shall other third parties designated by NeurogesX and approved by LTS in written form (which approval shall not be unreasonably withheld) for compliance with this
Agreement, at [***]; provided that to the extent that a particular vendor does not allow audits by LTS customers, LTS shall use [***] to (i) receive the consent of its vendor to have such audit conducted by a third party or (ii) to the
extent it has the right to do so, perform such audit on NeurogesXs behalf at NeurogesXs expense. To the extent LTS is required under the Arzneimittelgesetz (German pharmaceutical law) to audit the other sub-contractors or
vendors of NeurogesX with respect to the Patches LTS shall have the right to do so at [***], subject to audit procedures to be reasonably agreed between the Parties and the particular sub-contractor or vendor.

3.8 Reporting Safety and Toxicity Problems. Each Party shall promptly advise the other Party of any safety or toxicity problems of which it becomes aware
regarding the Patches or Raw Materials used in the manufacture of the Patches.

3.9 Recalls. To the extent (i) any governmental or
regulatory authority issues a request, directive or order that the Patches be recalled or withdrawn, or (ii) a court of competent jurisdiction orders a recall or withdrawal of Patches, or (iii) either Party determines after consultation
with the other Party, that the Patches should be recalled or withdrawn due to safety issues, the Parties shall recall or withdraw the Patches as set forth in this Section 3.9.

(a) Control of Recall Activities. As between the Parties, NeurogesX shall control and coordinate all activities, including making all contacts with
regulatory authorities, it deems necessary in connection with such recall or withdrawal.

(b) Initial Allocation of Recall Expenses. The
Parties shall initially allocate all expenses (including out-of-pocket expenses) [***] related to the execution of any recall or withdrawal of the Patches (Logistic Costs) [***] between the Parties, provided that in the case of
Section 3.9(iii) above, if the Parties do not mutually agree on having the Patches recalled or withdrawn, then the Party requesting the recall or withdrawal [***], in each case subject to the final allocation between the Parties as set forth in
Section 3.9(c).

(c) Final Allocation of Recall Expenses. All Logistic Costs shall be borne by the Party which is [***]. The
responsibility of a Party shall be determined in accordance with the principles of Article 9. For example, [***]. Notwithstanding the foregoing, LTS total liability under this Section 3.9(c) for Logistic Costs shall be limited to an
amount equal to [***] plus any additional amounts covered by LTS insurance coverage, except in the case of LTS gross negligence or willful misconduct. In case of LTS [***], LTS liability for Logistic Costs shall not be so

PAYMENT

5.1 Transfer Price. NeurogesX shall pay LTS the price set forth in Exhibit A (the
Transfer Price) for each Patch ordered by NeurogesX and delivered by LTS hereunder. All payments hereunder shall be made in [***], by direct bank transfer to an account as designated in LTS invoice. Such payments shall be made by
NeurogesX within [***] days after the later of (a) receipt of an invoice, or (b) the end of the Acceptance Period (as defined in Section 8.2(a) below) for the respective Patches. In addition, in the event NeurogesX has rejected, in
accordance with Section 8.2(a), the Patches prior to the time payment of the Transfer Price is due and LTS is required to deliver replacement Patches in accordance with Section 8.2(b), then the Transfer Price shall not be due until
replacements therefore have been received in accordance with Section 8.2(b). In the event LTS disagrees that Patches rejected were Defective, then NeurogesX shall pay [***] of the Transfer Price until a laboratory has determined whether such
Patches were Defective in accordance with Section 8.2(c). In case the laboratory determines that Patches were Defective, then such payment shall be [***]. In case the laboratory determines that Patches were not Defective, NeurogesX shall
immediately pay the remaining [***] of the Transfer Price. NeurogesX shall pay interest at an annual rate of [***] above [***] for any payments of Transfer Price which LTS did not receive on the date payment is due under this Section 5.1.

5.2 Royalties.

(iii) For the avoidance of doubt, if NeurogesX elects to exercise the option set forth in Section 6.4(f)(ii), the royalty set forth
in Section 6.4(f)(ii) shall not be additional to those in Section 6.4(f)(i), NeurogesX shall in this case only pay the royalty set forth in Section 6.4(f)(ii) with respect to the selected jurisdictions. In addition, for the avoidance
of doubt, the royalty set forth in Section 5.2 above shall not apply to the Patches made under the license set forth in this Section 6.4, and the royalty set forth in this Section 6.4(f) shall not apply to the Patches purchased from
LTS.

6.5 Sublicensing. In the event NeurogesX desires to grant a sublicense to any third party under the licenses set forth in
Section 6.2 and/or 6.4, NeurogesX is free to do so, provided that

(a) LTS is informed of the identity of the Sublicensee and the
scope of rights that are being granted;

(b) those Sublicensees shall be obligated to indemnify LTS regarding IP Claims and product
liability to the extent NeurogesX is so obligated under Sections 9.2 and 9.3(b); and

(c) those Sublicensees shall be obligated to maintain

INTELLECTUAL PROPERTY

7.1 Inventions relating to the Patch.

(a) LTS Owned. All inventions developed by the Parties or by either Party under this Agreement or the Clinical Supply Agreement solely relating to
LTS existing TTS technology, including but not limited to design, formulation, manufacturing, testing and packaging of TTS, shall be the property of LTS (LTS IP). LTS shall not use any LTS IP for the development of TTS containing
VR1-Ligand until [***], other than for NeurogesX. Thereafter, until [***], NeurogesX shall have a right of first refusal in case LTS commences development of TTS which contain any VR1-Ligand using 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 or by either Party under this Agreement or the Clinical Supply Agreement solely relating to
medical uses of any VR1-Ligand 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. All other
inventions developed by the Parties or by either Party under this Agreement or the Clinical Supply Agreement shall be the joint property of the Parties (Joint IP), provided that it does not belong under Section 7.1(a) or (b) to
either LTS IP or NeurogesX IP. 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 shall only have the right to exploit and license the Joint IP for VR1-Ligand applications and products, and LTS shall only have the
right to exploit or license the Joint IP for any applications and products other than VR1-Ligand applications and products.

(d) Exclusive
License. Accordingly, the Parties grant to each other licenses under the Joint IP (which to avoid any doubt for purposes of these licenses includes all patent applications and patents claiming the inventions included therein) as follows:

(i) NeurogesX hereby grants to LTS an exclusive (even as to NeurogesX), royalty-free, fully-paid, freely sublicensable (though one or more layers of
sublicensees without consent), perpetual, irrevocable, worldwide license under the Joint IP to [***] Notwithstanding Section 7.3 below, LTS shall have the [***] to enforce the Joint IP against infringement within the scope of the license set
forth in this Section 7.1(d)(i) and to retain [***] recoveries therefrom, and NeurogesX shall cooperate with LTS, at LTS reasonable request and expense; however, nothing herein shall require NeurogesX to join any such action as a party to
any such action. For clarity, the Parties intend that LTS shall have sufficient rights to enforce such Joint IP as set forth in this Section 7.1(d)(i) without NeurogesX joining as a co-plaintiff.

(ii) LTS hereby grants to NeurogesX an exclusive (even as to LTS), royalty-free, fully-paid, freely sublicensable (though one or more layers of
sublicensees without consent),

perpetual, irrevocable, worldwide license under the Joint IP to make, have made, use, sell, offer to sell, and import product candidates and products that
contain any VR-1 Ligand(s) and/or are VR-1 Ligand applications and products. Notwithstanding Section 7.3 below, NeurogesX shall have the sole right to enforce the Joint IP against infringement within the scope of the license set forth in this
Section 7.1(d)(ii) and to retain all recoveries therefrom, and LTS shall cooperate with NeurogesX, at NeurogesXs reasonable request and expense; however, nothing herein shall require LTS to join any such action as a party to any such
action. For clarity, the Parties intend that NeurogesX shall have sufficient rights to enforce such Joint IP as set forth in this Section 7.1(d)(ii) without LTS joining as a co-plaintiff.

7.2 Prosecution of Patents Covering the Patch.

(a) As used in Sections 7.2 and 7.4, prosecute means the procedure(s) involved in securing patent rights in patent offices worldwide.

(b) LTS shall have the right, [***] to file, prosecute and/or maintain any patent or patent application solely owned by LTS covering the Patches. With respect to such LTS patents and patent applications that are
specific to the Patch, including [***] and foreign counterparts thereof, NeurogesX shall have the right to review and consult with LTS regarding the prosecution and maintenance thereof; provided however that in the event NeurogesX does not provide
comments within a period of [***] days after receipt of a respective draft brief or office action by LTS, NeurogesX shall be deemed to have waived its right to review and consult.

(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
[***] days prior to the due date for any action or payment. NeurogesX shall then have the right, to file, prosecute and/or maintain any such patent or patent application.

(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 [***] (except as
set forth in this Section 7.2(e[***]. 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 7.3 below.

7.3 Third Party Infringement in the Field. Each Party agrees to [***] notify the other Party if it becomes aware
of any third partys TTS in the Field that infringes LTS patents covering the Patch (an Infringement). LTS shall have the [***], but not the obligation, to enforce its patents against any Infringement. LTS shall [***] control
any such enforcement action. LTS shall keep NeurogesX informed of the proceeding of such enforcement. In case NeurogesX believes LTS is not [***] pursuing the enforcement, NeurogesX shall have the

[***] 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 Article 6 of this Agreement. LTS shall not settle any Infringement action without the prior written approval of
NeurogesX. In the event LTS notifies NeurogesX within [***] days after notice of an alleged Infringement by either Party that it intends to file suit against any alleged Infringement, or does not give any notification whether it intends to file suit
within [***] 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 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 7.3, at NeurogesXs cost and expense.

(a) If LTS decides to enforce its patents against Infringement and NeurogesX permits LTS to claim NeurogesX damages, then any proceeds from such
enforcement of its Patents recovered from any such Infringement action shall be divided (i) [***] between NeurogesX and LTS unless clause (ii) applies, or (ii) [***] to NeurogesX and [***] to LTS with respect to recoveries for
Infringement in a jurisdiction for which NeurogesX has elected to pay a higher royalty under Section 5.2(b) or 6.4(f)(ii) above, in each case after first subtracting [***].

(b) In the event NeurogesX is given the right to enforce LTS patents against Infringement and LTS permits NeurogesX to claim LTS damages,
then any proceeds from such enforcement of LTS patents recovered from any such Infringement action shall be divided (i) [***] between NeurogesX and LTS unless clause (ii) applies, or (ii) [***] to NeurogesX and [***] to LTS with
respect to recoveries for Infringement in a jurisdiction for which NeurogesX has elected to pay a higher royalty under Section 5.2(b) above or 6.4(f)(ii), in each case after first subtracting [***].

7.4 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, including without limitation participating (but not joining as a plaintiff) in enforcement actions, the other Party 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.

7.5 IP Review by LTS. LTS
shall review on a [***] basis the intellectual property rights relevant for LTS obligations hereunder. LTS shall give NeurogesX a confirmation in writing [***] a year (on or about [***] of each year) that, to the best of its actual knowledge,
LTS does not infringe third parties intellectual property rights with respect to the Patches.

7.6 Blocking Patents.

(a) In the event a Party becomes aware of a Blocking Patent, such Party shall [***] notify the other Party giving such [***] details as such Party may be
aware, and



***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.

the Parties shall discuss the situation in [***] and agree on a plan to address the situation, with the mutual objective of removing the risk posed by such
Blocking Patent so that the Parties may continue performance under this Agreement, including if appropriate and agreed by the Parties, by licensing and/or challenging such Blocking Patent. In the event the Parties agree on a plan to address such
Blocking Patent, the Parties shall designate a lead Party to use Reasonable Commercial Efforts to perform such plan. It is understood that the costs of any license obtained with respect to a Blocking Patent (to the extent allocable to the
manufacture, use or sale of Patches hereunder) will be shared by the Parties in proportion to their indemnification obligations for IP Claims under Section 9.2. It is understood and agreed that notices, communications and discussions under this
Section 7.6 shall not be construed as [***] by either Party. In addition, all notices, communications and discussions under this Section 7.6 shall be deemed protected by the [***].

(b) After discussing the matter in [***] as described in Section 7.6(a) above, LTS and NeurogesX shall each have the right to [***] under this
Agreement with respect to the affected country upon written notice (Notice of Suspension), until the risk of infringing such Blocking Patent has been removed, including if a Party or a Sublicensee has obtained a license with respect to
the Blocking Patent for such country, or otherwise if in the [***] opinion of the Suspending Partys counsel, such risk is removed. In the event LTS elects to provide a Notice of Suspension, then such notice shall be deemed a Failure
Event under Section 6.4(a) above, effective upon receipt of the Notice of Suspension, provided however that the Parties shall discuss resuming their obligations as foreseen in case of termination under Section 11.3.

(c) Notwithstanding the foregoing, in the event that upon receiving a Notice of Suspension, a Party disputes in good faith such notice, then the Party
providing the Notice of Suspension may [***] its performance as set forth in this Section 7.6 if it can show by an opinion of an independent counsel, approved by the other Party (whose approval shall not be unreasonably withheld), that the
determination of its counsel that a third partys intellectual property right would be infringed is [***]. Such opinion shall also summarize the underlying facts. The Parties shall cooperate to ensure that all attorney-client privilege and work
product privilege shall be protected with respect to the opinion. If the Party providing the Notice of Suspension does not propose an independent counsel, which is [***] to the other Party, then an independent counsel shall be appointed by the ICC
International Centre for Expertise in accordance with the rules for Expertise of the International Chamber of Commerce. Such independent counsel shall be a [***].

8.2 Patches. Subject to the limited liability provisions set forth in this Agreement, LTS represents and
warrants that the Patches delivered to NeurogesX (a) shall (i) be in conformity with the Specifications, (ii) be manufactured in accordance with Current GMP and the Quality Assurance Agreement, and (iii) comply with all
Regulatory Requirements, and (b) no later than [***] days after initiation of the manufacture thereof, be released for shipment by LTS and made available for ex works delivery to NeurogesX.

(a) Rejection of Defective Patches. NeurogesX may reject Defective Patches, 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 (which evidence is subject to confirmation under Section 8.2(c) below), by delivering to LTS written notice of rejection, and if practical,
specifying the nature of the Defect and the Patches lot number, within [***] days after actual receipt by NeurogesX or its designee of the applicable shipment (the Acceptance Period). In the case of Patches with Defects that are not
reasonably discoverable upon NeurogesXs [***] incoming quality control testing (Latent Defects), NeurogesX may reject such Patches within [***] days after discovery of the Latent Defects. After said [***] days period or after the
Acceptance Period, whichever is applicable, the Patches shall be deemed accepted.

(b) Replacement of Defective Patches. During the [***]
month period commencing on the date the Patches are delivered to NeurogesX, LTS shall promptly (and in any event within [***] days of receipt of notice of rejection) deliver to NeurogesX, at LTS own cost and risk, including shipping costs and
Active Ingredient costs, replacements for any rejected Defective Patches, up to the [***] contained in the applicable lot. The foregoing shall be NeurogesXs [***] for the rejection of Defective Patches, but does not limit any remedies
NeurogesX may have under other sections of this Agreement.

(c) Confirmation of Cause of Defects. LTS shall have the right to examine any
Patches rejected by NeurogesX, provided such examination shall not delay the shipping of replacement Patches. In the case LTS disagrees that the rejected Patches are subject to this Section 8.2, 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. In making its determination, such laboratory shall take into
consideration any evidence provided by LTS that the Patches complied with the Specifications at the time of shipment, and also any evidence provided by NeurogesX that the Patches were correctly handled and stored (i.e. in accordance with the
Specifications) by NeurogesX and third parties under authority of NeurogesX. The determination of such laboratory shall be [***] upon the Parties. The Party against whom the determination is made shall be responsible for the [***], as well as the
costs of the replacements for the rejected Patches at issue, including [***].

8.3 Disclaimer of Warranties. EXCEPT AS EXPRESSLY SET FORTH

Information within one of such exceptions.

10.3 Each receiving Party shall limit access to the Confidential Information from the
disclosing Party to those of its officers, employees and consultants who need to know such Confidential Information for the purpose of this Agreement and who will be advised of the conditions of this Agreement. In case a receiving Party wishes to

10.7 Expiration or Termination of this
Agreement. Upon any expiration or termination of this Agreement, each Party shall promptly return all Confidential Information of the other Party, provided however, that each Party may retain such Confidential Information as reasonably necessary to
exercise rights hereunder or perform obligations hereunder that survive such expiration or termination, and each Party may retain one copy of the Confidential Information thereof in its legal files solely for archival purposes.

ARTICLE 11

TERM AND TERMINATION

11.1 Term. Unless terminated in accordance with this Article 11, this Agreement shall be in effect until ten (10) years after the

(60) days thereafter.

11.3 Termination due to Blocking Patents in a Country. Either Party shall have the right to terminate this
Agreement with respect to a particular country upon written notice, in the event that a court of competent jurisdiction determines in a final non-appealable judgment, in a case involving one of the Parties or a Sublicensee of NeurogesX, that the
manufacture or sale of the Patch in such country pursuant to this Agreement infringes a Blocking Patent. In the event a Party or a Sublicensee thereafter obtains a license with respect to such Blocking Patent in such country, or otherwise removes in
the reasonable opinion of the other Partys counsel the risk of

infringing a Blocking Patent in such jurisdiction, the Parties shall discuss in good faith to resume their obligations (including the terms and conditions
thereof) under this Agreement with respect to such country.

11.4 Other Termination.

(a) Failure Event. NeurogesX shall have the right to terminate this Agreement at any time in the case of a Failure Event (as defined in Section 6.4),
provided that such Failure Event is due to LTS not employing [***] to supply Patches. In case NeurogesX purchases all its commercial requirements of Patches from a third party after a Failure Event, then LTS shall have the right to terminate the
Agreement upon written notice. In case LTS declines the offer to supply NeurogesXs requirements set forth in Section 6.4(e), either Party shall have the right to terminate the Agreement upon written notice.

(b) Termination upon Abandonment of the Patch. NeurogesX shall have the right to terminate this Agreement upon [***] months written notice in the event
NeurogesX and its Sublicensees have abandoned development and commercialization of the Patch worldwide. In this case LTS may discuss with NeurogesX obtaining a license for its development and commercialization of the Patches on terms (financial and
otherwise) to be mutually agreed; provided that neither Party shall be obligated to discuss such license for more than [***] and neither Party shall be obligated to agree to granting or accepting such license, nor any particular terms and conditions
for such license.

11.5 Survival. Sections 3.2, 3.8 (to the extent necessary to comply with the other Partys legal obligations after
expiration or termination), 3.9 (with respect to Patches supplied by LTS to NeurogesX prior to such expiration or termination), 6.2, 6.4, 6.5, 7.1, 7.2, 7.4 and Articles 1, 8 (with respect to Patches delivered by LTS under this Agreement), 9 (with
respect to Patches delivered by LTS under this Agreement), 10, 11 and 12 shall survive any expiration or termination of this Agreement. Except as set forth in this Section 11.5, all other sections of this Agreement shall terminate upon any
expiration or termination of this Agreement.

(a) Accrued Liabilities. Termination of this Agreement for any reason shall not release
either Party hereto from any liability which at the time of such termination has already accrued to the other Party.

(b) Backup
Manufacturing License. In the event of termination of this Agreement by NeurogesX under Section 11.4(a) or 11.2 or by LTS under Section 11.4(a) or 11.3 any time after NeurogesX has the right to exercise its Backup License the following
Sections shall survive (in addition to those described in Section 11.5 above), Sections 5.3 (as it relates to Section 6.4), 6.4, and 7.3 shall survive such termination. For clarity, an election to have this Agreement expire after a Failure
Event shall be treated as a termination of this Agreement under Section 11.4(a) by either or both Parties. In any other termination or expiration of this Agreement, Section 7.3 shall survive only with respect to infringement occurring
prior to such termination or expiration.

(c) Pending Orders. In the event of any termination or expiration of this Agreement other than
termination under Section 11.2, 11.3 or 11.4(a), unless otherwise mutually agreed, all pending orders for the Patches shall be cancelled, and NeurogesX shall reimburse LTS for the

cost of Raw Materials and works-in-progress of Patches that cannot be used by LTS in the manufacture of products for its other clients, and such Raw
Materials and works-in-progress shall be disposed of or transferred in accordance with NeurogesXs instruction at NeurogesXs expense. In the event of termination of this Agreement under Section 11.3 with respect to a country, unless
otherwise mutually agreed, all pending orders for Patches specifically for such country shall be cancelled.

ARTICLE 12

MISCELLANEOUS

Resolution.

(a) Disputes. The Parties shall attempt in good faith to resolve promptly any dispute arising out of or relating to this
Agreement by negotiation. If the matter cannot be resolved in the normal course of business, any interested Party shall give to the other Party written notice of any such dispute not resolved, after which the dispute shall be referred to the
principal executive officers of both Parties or their designees who shall likewise attempt to resolve the dispute. If the dispute has not been resolved by negotiations within [***] days of such written notice, each Party may have the dispute
arbitrated in accordance with Section 12.1(b) below.

Agreement or the performance, breach or termination thereof, shall be finally settled by binding arbitration under the rules of arbitration of the International Chamber of Commerce by [***] appointed in accordance with said rules, unless the Parties

own attorneys and expert fees.

(c) THE UNDERSIGNED PARTIES ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT
THAT IT MAY BE WAIVED AND AFTER CONSULTING WITH COUNSEL, KNOWINGLY AND VOLUNTARILY WAIVE ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS AGREEMENT AND ANY AGREEMENT
CONNECTED THERETO.

incur any expense, liability or obligation, express or implied, on behalf of the other Parties.

12.5 English Language. This Agreement is

this Agreement shall be in the English language.

12.6 Force Majeure. Neither Party shall be responsible or liable to the other Party for,
nor shall this Agreement be terminated as a result of, any failure to perform any of its obligations hereunder, if such failure results from circumstances beyond the control of such Party, including, without limitation, requisition by any government
authority, the effect of any statute, ordinance or governmental order or regulation, wars, strikes, lockouts, riots, epidemic, disease, an act of God, civil commotion, fire, earthquake, storm, failure of public utilities, common carriers or

shall resume performance under this Agreement as soon as feasible whenever such cause is removed; provided, however, that the foregoing shall not be construed to require either Party to settle any dispute with any third party, to commence, continue
or settle any litigation, or to incur any unusual or extraordinary expenses.

this Agreement shall be made in writing and given by prepaid, first class, certified mail, return receipt requested, and shall be deemed to have been given on the date received by the addressee at the following address or such other address as may

regulations in connection with its activities pursuant to this Agreement.

12.9 No Waiver. A waiver, express or implied, by either LTS or
NeurogesX of any right under this Agreement or of any failure to perform or breach hereof by the other Party hereto shall not constitute or be deemed to be a waiver of any other right hereunder or of any other failure to perform or breach hereof by
such other Party, whether of a similar or dissimilar nature thereto.

12.10 Severability. If any provision of this Agreement shall be found
by a court to be void, invalid or unenforceable, the same shall be reformed to comply with applicable law or stricken if not so conformable, so as not to affect the validity or enforceability of the remainder of this Agreement, and the remainder of

Party.
