3.3 Diligence. Except as specifically provided herein or as otherwise mutually agreed upon by the Parties, Adolor shall be responsible for conducting all clinical studies, development and commercialization activities for Licensed Products in the Territory. Adolor shall use Commercially Reasonable Efforts to develop and commercialize a Licensed Product within the Territory. Subject to the foregoing, Adolor shall have sole discretion in determining which Licensed Products it will submit for Regulatory Approval, in which countries it will file for Regulatory Approvals of such Licensed Products and in which countries it will commercialize such Licensed Products in the Territory.

3.4 Reports.

(a) By Adolor. Every six (6) months following the Effective Date, Adolor shall provide EpiCept a written report summarizing the efforts and accomplishments of Adolor, its Affiliates and its sublicensees during the preceding six (6) month period in developing and commercializing Licensed Products and their development and commercialization plans for the subsequent six (6) month period. Such reports shall include, without limitation, summaries of scientific and clinical data obtained in furtherance of Adolor’s attempts to develop and commercialize Licensed Products and a showing of compliance with Adolor’s obligations under Section 3.3 above. EpiCept shall have the right to provide Adolor with comments regarding Adolor’s development and commercialization plans for the subsequent six (6) month period contained in such reports and Adolor shall take such comments into consideration, provided that Adolor shall retain final decision-making authority with respect to any and all such development and/or commercialization plans.

(b) By EpiCept. Every six (6) months following the Effective Date, EpiCept shall provide Adolor a written report summarizing the efforts and accomplishments of EpiCept, its Affiliates and sublicenses during the preceding six (6) month period in developing and commercializing Licensed Products.

basis such information in its possession relating to the LidoPAIN^® SP Product and any other Licensed Product as may be required for the foregoing regulatory activities, and otherwise provide reasonable assistance to Adolor in complying with all regulatory obligations in the Territory, including without limitation, safety updates, amendments, annual reports, pharmacovigilance filings, investigator notifications, manufacturing facility inspections and certifications and product approvals. Except as required by Section 3.1(d), Adolor shall reimburse EpiCept for the out-of-pocket costs and expenses incurred by EpiCept in complying with such request. Adolor shall be responsible for interfacing, corresponding and meeting with all Regulatory Authorities in the Territory with respect to any Licensed Product. Except as required by applicable law, EpiCept shall not communicate directly with the FDA or any other Regulatory Authority in the Territory relating to the LidoPAIN^® SP Product or any other Licensed Product without the prior written consent of Adolor. In furtherance thereof, EpiCept shall refer all FDA communications relating to any Licensed Product to Adolor. EpiCept shall cooperate with Adolor to provide all reasonable assistance and take all actions reasonably requested by Adolor that are necessary to comply with any law applicable to any Licensed Product, including, but not limited to, reporting of adverse drug experience reports (and serious adverse drug experiences) to Regulatory Authorities in the Territory.

3.6 Regulatory Matters; Adolor’s Assistance. In the event that a Regulatory Authority outside of the Territory in a country where Adolor is developing Licensed Products requests that EpiCept provide it with information within Adolor’s possession, Adolor will make available to EpiCept such tangible written information in Adolor’s possession and control that is requested by such Regulatory Authority, which information shall be presented in a form which satisfies the requirements of applicable regulatory guidelines and/or regulations for such Regulatory Authority. Notwithstanding the foregoing, Adolor may instead agree to provide such information directly to the applicable Regulatory Authority, as the case may be, or to an independent third party of its choosing, and shall respond directly (or through its independent agent) to any questions or inquiries from such Regulatory Authority regarding the information. In addition, Adolor shall have no duty to disclose any of its proprietary or confidential information to any Regulatory Authority or any other party, unless the Regulatory Authority in question provides for the protection of such proprietary or confidential information from disclosure in a manner substantially similar to that provided by the FDA. EpiCept shall reimburse Adolor for the out-of-pocket costs and expenses incurred by Adolor in complying with any such requests. Adolor shall endeavor in good faith to cooperate and comply with any requests from EpiCept or from any Regulatory Authority pursuant to this Section 3.6.

3.7 Adverse Event Reporting.

(a) Each Party shall, and shall require its respective Affiliates to:

(i) to the extent permissible under time constraints and reporting requirements, provide to the other Party in advance of initial or periodic submission to Regulatory Authorities any and all adverse event reports and Serious Adverse Drug Experience reports from clinical trials and commercial experiences with each Licensed Product;

- 12 -

[**] CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL PORTION OMITTED AND FILED SEPARATELY WITH THE COMMISSION

(ii) provide such adverse event reports and Serious Adverse Drug Experience reports to the other Party contemporaneously with the provision of such reports to the applicable Regulatory Authority; and

(iii) adhere to all requirements of applicable laws, rules and regulations which relate to the reporting and investigation of adverse events and Serious Adverse Drug Experiences and keep the other Party informed of such events.

(b) If a Party contracts with a Third Party for research to be performed by such Third Party on any of the Licensed Products, that Party shall require such Third Party to report to the contracting Party the information set forth above.

3.8 Adolor’s Right of First Refusal.

(a) If, at any time, EpiCept receives an offer by a Third Party to develop or commercialize Licensed Products outside the Territory or an OTC Product anywhere in the world (the “Third Party Offer”), EpiCept shall offer in writing to Adolor an exclusive license to make, have made, use, develop, sell, and have sold such Licensed Product or OTC Product in such country or countries on the same terms as the Third Party Offer. Such written notice (an “Offer Notice”) shall specify (i) the Licensed Product(s) or OTC Product subject to such Third Party Offer, (ii) any pre-clinical and clinical data relating to such Licensed Product(s) or OTC Product and (iii) the fees, terms, conditions and other material items related to such Third Party Offer. Within thirty (30) days after receipt of an Offer Notice, if Adolor or its Affiliate desires to negotiate a definitive agreement related to such Third Party Offer, Adolor shall send a written reply to such effect (an “Adolor Reply”). Upon receipt of an Adolor Reply, Adolor and EpiCept shall negotiate the terms thereof in good faith for a period not to exceed ninety (90) days, which period may be mutually extended in writing by the Parties (the “Negotiation Period”).

(b) EpiCept shall not negotiate, enter into, or agree to enter into an agreement for the manufacture, use, or sale of a Licensed Product or OTC Product with any person or entity other than Adolor during the pendency of such thirty (30) day period after an Offer Notice and during any Negotiation Period. Accordingly, EpiCept shall not offer, negotiate, or enter into such an agreement for a Licensed Product with a Third Party, unless (i) Adolor fails to send an Adolor Reply within the thirty (30) day period after the Offer Notice or (ii) Adolor fails to agree to enter into a definitive agreement with EpiCept with respect to any such Offer Notice on the terms of the Third Party Offer within the Negotiation Period. In the case of the foregoing clauses (i) and (ii), EpiCept may enter into a definitive agreement with such Third Party with respect to such Third Party Offer; provided, however, that if any terms of such agreement with such other person or entity when taken as a whole would be less favorable to EpiCept than as specified in the Offer Notice therefor, EpiCept shall deliver a new Offer Notice to Adolor specifying such variations from the initial Offer Notice, whereupon Adolor shall have another thirty (30) day period to send a new Adolor Reply and, if it does so, another Negotiation Period therefor. The Parties hereby acknowledge and agree that neither Adolor nor EpiCept shall have an obligation to enter into a definitive agreement with respect to any such Offer Notice.

3.9 EpiCept Right to Co-Promote. EpiCept, at its option, shall have the right to negotiate to become Adolor’s co-promotion partner as set forth in this Section 3.9. Within thirty

[**] CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL PORTION OMITTED AND FILED SEPARATELY WITH THE COMMISSION

(30) days after Adolor’s first filing of an NDA or the equivalent thereof in a country other than the United States in the Territory for its first Licensed Product, Adolor shall notify EpiCept in writing (the “NDA Notice”). Unless EpiCept shall have waived this option to negotiate to become Adolor’s co-promotion partner in writing within thirty (30) days following receipt by EpiCept of the NDA Notice, then Adolor and EpiCept shall negotiate in good faith to reach agreement on terms for the co-promotion of such Licensed Product for a period of up to sixty (60) days commencing on the date of the NDA Notice. Notwithstanding the foregoing, neither Party shall be under any obligation to enter into such a co-promotion arrangement. Unless mutually agreed to by the Parties, no such co-promotion arrangement shall effect any change to the financial terms of this Agreement and EpiCept shall be solely responsible for the costs and expenses of its sales representatives. Furthermore, it is understood and agreed that Adolor may refuse to enter into any such co-promotion arrangement if it would, in Adolor’s reasonable discretion, adversely affect Adolor’s planned commercialization of the Licensed Product. It is further understood and agreed that, to the extent that the Parties enter into such a co-promotion arrangement, EpiCept shall cause its sales representatives to comply with all instructions and decisions of Adolor with respect to the promotion of the Licensed Product.

3.10 Supply.

(a) Supply for Development. At Adolor’s sole option, EpiCept shall be responsible to supply, or to obtain supply, for Adolor’s requirements in the Territory of Licensed Product for clinical and other development activities in accordance with Adolor’s obligations under this Agreement. Alternatively, Adolor, in its sole discretion, shall be entitled to supply and manufacture clinical supplies of Licensed Product in the Territory. The Parties acknowledge that Third Party subcontractors may be engaged by Adolor to carry out such manufacture and supply on Adolor’s behalf. Within sixty (60) days after the Effective Date, in the amounts and at a price per patch set forth on Schedule 3.10(a), EpiCept shall deliver to a location designated by Adolor LidoPAIN^® SP Product 9.5% patches and LidoPAIN^® SP Product placebo 0.0% patches that are stored at PharmaForm.

(b) Cost of Supply. EpiCept shall supply such Licensed Product to Adolor at a price per Licensed Product equal to the EpiCept Cost of Goods or a price otherwise mutually agreed to in writing by the Parties.

(c) Clinical Supply. If Adolor desires to order clinical supplies from EpiCept, Adolor shall place orders for clinical supplies of Licensed Product on a purchase order basis on at least sixty (60) days’ written notice prior to the requested delivery date. The Parties acknowledge that Third Party subcontractors may be engaged by EpiCept to carry out such manufacture and supply on EpiCept’s behalf.

(d) Commercial Supply. Adolor shall be responsible for the manufacture of the commercial supply of Licensed Products for commercialization in the Territory. The Parties acknowledge that Third Party subcontractors may be engaged by Adolor to carry out such manufacture and supply on Adolor’s behalf. Adolor shall offer, or shall cause its Third Party subcontractors to offer, to EpiCept and/or its Affiliates and/or its sublicensees supplies of Licensed Product for commercialization outside of the Territory, which offer EpiCept may accept or in lieu thereof EpiCept may separately arrange for manufacture of commercial supply of Licensed Product for commercialization outside of the Territory.

[**] CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL PORTION OMITTED AND FILED SEPARATELY WITH THE COMMISSION

For purposes of clarification, each of the foregoing Milestone Payments shall be made only once and upon the first occurrence of each milestone, regardless of the number of Licensed Products or occurrences of each milestone for Licensed Products under the same NDA. In addition, notwithstanding any other provision of this Agreement to the contrary, if any milestone event described in this Section 4.2 is achieved prior to or in the absence of the achievement of any preceding milestone (as designated by the order of clauses (a) through (e) of this Section 4.2), then, effective upon the occurrence of such milestone, any preceding milestone event for which the milestone has not been paid shall be deemed to have been achieved and the applicable payment shall become due and payable. For the avoidance of doubt, with respect to clause (f), a supplemental NDA shall not be considered a new NDA for purposes of determining achievement of such milestone event.

ARTICLE 5

ROYALTIES

5.1 Royalty Rates. Subject to the provisions of this Article 5, Adolor shall pay the following royalties in accordance with this Article 5 (“Royalties”) on a Licensed Product-by-Licensed Product basis based on aggregate Net Sales of each Licensed Product in the Territory, as follows:

(a) [**] of that portion of aggregate Net Sales of such Licensed Product that is less than or equal to [**] in a calendar year.

(b) [**] of that portion of aggregate Net Sales of such Licensed Product that is greater than [**] in a calendar year.

5.2 Royalty Term. Subject to the provisions of Section 5.3, the Royalties set forth in Section 5.1 shall be payable on a Licensed Product-by-Licensed Product basis and a country-by-country basis for so long as there exists in such country a Valid Claim of an issued patent within the EpiCept Licensed Patents or EpiCept Improvements covering a Licensed Product, or, if longer, the tenth (10th) anniversary of the First Commercial Sale of such Licensed Product in such country; provided, however, that such Royalties shall be reduced by [**] for any portion of such payment term during which no such Valid Claim of an issued patent within the EpiCept Licensed Patents or EpiCept Improvements exists in such country.

5.3 Royalty Reductions.

(a) For Third Party Licenses.

(i) Assessment of Third Party Intellectual Property Rights. If Adolor reasonably believes that the sale of Licensed Products would infringe the intellectual property rights of a Third Party unless a license is obtained from such Third Party, Adolor may enter into a license with such Third Party and such license shall be subject to this Section (a). Adolor shall provide EpiCept with written notice of such belief. Such notice shall include documents supporting Adolor’s position. EpiCept shall have forty-five (45) days to review the notice from Adolor and to agree or disagree with Adolor’s belief. If EpiCept disagrees with Adolor’s belief, then EpiCept shall provide Adolor with documents supporting EpiCept’s position. Adolor shall have forty-five (45) days to review the documents from EpiCept. All documents exchanged by the parties shall be maintained in confidence and shall not be used for any other purpose than the resolution of the scope of a Third Party’s intellectual property rights as it pertains to the sale of a Licensed Product as set forth in this Agreement. If Adolor maintains its original position after such review period, then the matter shall be referred first to the officers of EpiCept and Adolor having responsibility for the subject matter of the dispute, or their designees. Such officers, or their designees, as the case may be, shall negotiate in good faith to resolve such dispute in a mutually satisfactory manner for thirty (30) days. If such efforts do not result in a mutually satisfactory resolution of the dispute, the matter shall be referred to the chief executive officer of each Party, or their respective designees. Such individuals shall negotiate in good faith to resolve such dispute in a mutually satisfactory manner for thirty (30) days, or such longer period of time as the Parties may agree. If such efforts do not result in a mutually satisfactory resolution, the dispute shall be finally settled by the Independent Party selected pursuant to Section 5.3(a)(ii).

(ii) Appointment of Independent Party. If a dispute with respect to a Third Party license cannot be resolved by Adolor and EpiCept pursuant to Section 5.3(a)(i), then Adolor and EpiCept shall, within thirty (30) days, select and retain a neutral person bound to confidentially by profession who is independent and disinterested with respect to the Parties (the “Independent Party”). The Independent Party shall be a patent attorney knowledgeable in the biopharmaceutical area. Neither Party shall unreasonably withhold agreement to the selection of a qualified Independent Party. The Parties shall share equally any and all fees, expenses, reimbursements and other out-of-pocket costs related to the engagement of the Independent Party.

(iii) Reductions. If the Independent Party determines that the sale of a Licensed Product would not infringe the intellectual property rights of a Third Party, then Adolor shall not be entitled to any reductions in Royalties or Other Payments for a Licensed Product under this Section (iii) as a result of entering into a license with such Third Party. If, however, the Independent Party determines that the sale of a Licensed Product would infringe the intellectual property rights of a Third Party unless a license is obtained from such Third Party, Adolor may offset [**] of any such Third Party royalty payments or Other Payments (as defined below) against the Royalties. Offsets for any such Third Party royalty payments for Net Sales in a quarter may be applied only against Royalties due hereunder for the same Net Sales in the same quarter. Offsets for Other Payments to such Third Parties may be

- 17 -

[**] CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL PORTION OMITTED AND FILED SEPARATELY WITH THE COMMISSION

amortized equally over the remaining portion of the ten (10) year period following First Commercial Sale in such country and applied in each corresponding quarter until the application of such Other Payments in their entirety. As used herein, “Other Payments” shall mean license issue fees or milestones, but shall specifically exclude equity investments. Notwithstanding the foregoing, nothing contained in this Section 5.3(a) shall reduce the Royalties otherwise due EpiCept by more than [**] for any given year.

(b) Reductions for Competition. All Royalties on a Licensed Product shall be reduced by [**] effective on and after the date when Competition occurs with respect to such Licensed Product in such country, provided that the reduction for any given year shall not reduce the Royalties paid to EpiCept for such year by more than [**]. If Competition ceases to exist, then beginning with the first calendar quarter after Competition does not exist, the Royalties on a Licensed Product will return to the percentages set forth in Section 5.1 until such time as Competition may again exist with respect to such Licensed Product.

(c) Request for Reductions. If Adolor reasonably and in good faith believes that a lower royalty rate is required in order to permit Adolor to commercialize the Licensed Product in a particular country with a reasonable profit, Adolor may notify EpiCept of such belief and their basis therefor and, if such notification is made, the Parties shall meet as promptly as practicable to discuss in good faith whether a reduction to the royalty rate for such Licensed Product in such country is appropriate provided that nothing shall require EpiCept to agree to such a reduction.

5.4 Reports and Payments.

(a) Cumulative Royalties. The obligation to pay Royalties under this Article 5 shall be imposed only once (i) with respect to any sale of the same unit of any Licensed Product, and (ii) with respect to a single unit of any Licensed Product regardless of the number or scope of the EpiCept Licensed Patents or EpiCept Improvements that, but for the licenses granted by EpiCept to Adolor hereunder, would be infringed by sale of the Licensed Product in the relevant country.

(b) Statements and Payment. Adolor shall deliver to EpiCept, within [**] days after the end of each calendar quarter, a report setting forth for such calendar quarter the following information for each Licensed Product: (i) Net Sales of such Licensed Product on a country-by-country basis; (ii) the basis for any adjustments to the Royalties payable on account of sales of such Licensed Product in any country; (iii) the Royalties due to EpiCept on account of sales of such Licensed Product; and (iv) the exchange rates used in calculating any of the foregoing. The total Royalties due on account of sales of Licensed Products during such calendar quarter shall be remitted at the time such report is made.

5.5 Taxes and Withholding. Any payments made by Adolor to EpiCept under this Agreement shall be reduced by the amount required to be paid or withheld pursuant to any applicable law, including, but not limited to, United States federal, state or local tax law (“Withholding Taxes”). Any such Withholding Taxes required by law to be paid or withheld

- 18 -

[**] CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL PORTION OMITTED AND FILED SEPARATELY WITH THE COMMISSION

shall be an expense of, and borne solely by, EpiCept. Adolor, as applicable, shall submit to EpiCept reasonable proof of payment of the Withholding Taxes, together with an accounting of the calculations of such taxes, within thirty (30) days after such Withholding Taxes are remitted to the proper authority. The Parties will cooperate reasonably in completing and filing documents required under the provisions of any applicable tax laws or under any other applicable law in connection with the making of any required tax payment or withholding payment, or in connection with any claim to a refund of or credit for any such payment.

5.6 Currency Exchange. With respect to Net Sales invoiced or expenses incurred in U.S. dollars, the Net Sales or expense amounts and the amounts due to EpiCept hereunder shall be expressed in U.S. dollars. With respect to Net Sales invoiced or expenses incurred in a currency other than U.S. dollars, the Net Sales or expense shall be expressed in the domestic currency of the entity making the sale or incurring the expense, together with the U.S. dollar equivalent, calculated using the arithmetic average of the spot rates on the last Business Day of each month of the calendar quarter in which the Net Sales were made or the expense was incurred. The “closing mid-point rates” found in the “Dollar spot forward against the Dollar” table published by The Financial Times, or any other publication as agreed to by the Parties, shall be used as the source of spot rates to calculate the average as defined in the preceding sentence. All payments shall be made by wire transfer in U.S. dollars to the credit of such bank account as shall be designated at least five (5) Business Days in advance by EpiCept in writing to Adolor.

5.7 Maintenance of Records; Audit. For a period of three (3) years, Adolor shall maintain, and shall require its respective Affiliates and sublicensees to maintain, complete and accurate books and records in connection with the sale of Licensed Products hereunder, as necessary to allow the accurate calculation consistent with generally accepted accounting principles of the Royalties due to EpiCept, including any records required to calculate any royalty adjustments hereunder. Once per calendar year, EpiCept shall have the right to engage an independent accounting firm reasonably acceptable to Adolor, which shall have the right to examine in confidence the relevant Adolor records as may be reasonably necessary to determine and/or verify the amount of Royalty payments due hereunder. Such examination shall be conducted, and Adolor shall make its records available, during normal business hours, after at least fifteen (15) days prior written notice to Adolor, as applicable, and shall take place at the facility(ies) where such records are maintained. Each such examination shall be limited to pertinent books and records for any year ending not more than thirty-six (36) months prior to the date of request; provided that EpiCept shall not be permitted to audit the same period of time more than once. Before permitting such independent accounting firm to have access to such books and records, Adolor may require such independent accounting firm and its personnel involved in such audit, to sign a confidentiality agreement (in form and substance reasonably acceptable to Adolor) as to any confidential information which is to be provided to such accounting firm or to which such accounting firm will have access, while conducting the audit under this paragraph. The EpiCept independent accounting firm will prepare and provide to each Party a written report stating whether the Royalty reports submitted and Royalties paid are correct or incorrect and the details concerning any discrepancies. Such accounting firm may not reveal to EpiCept any information learned in the course of such audit other than the amount of any such discrepancies. EpiCept agrees to hold in strict confidence all information disclosed to it, except to the extent necessary for EpiCept to enforce its rights under this Agreement or if

- 19 -

disclosure is required by law. In the event there was an underpayment by Adolor hereunder, Adolor shall promptly (but in no event later than thirty (30) days after such Party’s receipt of the independent auditor’s report so correctly concluding) make payment to EpiCept of any shortfall. In the event that there was an overpayment by Adolor hereunder, EpiCept shall promptly (but in no event later than thirty (30) days after EpiCept’s receipt of the independent auditor’s report so correctly concluding) refund to Adolor or credit to future royalties, at Adolor’s election, the excess amount. EpiCept shall bear the full cost of such audit unless such audit discloses an underreporting by Adolor of more than [**] of the aggregate amount of Royalties in any twelve (12) month period, in which case, Adolor shall bear the full cost of such audit.

5.8 Interest on Late Payments. Any failure by Adolor to make a payment of any undisputed amount when due shall obligate Adolor to pay interest to EpiCept at a rate equal to [**] per month (or the maximum allowed by law, if less), calculated on the basis of an a three hundred sixty (360) day year, the interest period commencing on the due date and ending on the payment date.

(a) In the case of a Third Party Claim made by any Person who is not a Party to this Agreement (or an Affiliate thereof) as to which a Party (the “Indemnitor”) may be obligated to provide indemnification pursuant to this Agreement, such Party seeking indemnification hereunder (“Indemnitee”) will notify the Indemnitor in writing of the Third Party Claim (and specifying in reasonable detail the factual basis for the Third Party Claim and to the extent known, the amount of the Third Party Claim) reasonably promptly after becoming aware of such Third Party Claim; provided, however, that failure to give such notification will not affect the indemnification provided hereunder except to the extent the Indemnitor shall have been actually prejudiced as a result of such failure.

(b) If a Third Party Claim is made against an Indemnitee and the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee therefor, the Indemnitor will be entitled, within one hundred twenty (120) days after receipt of written notice from the Indemnitee of the commencement or assertion of any such Third Party Claim, to assume the defense thereof (at the expense of the Indemnitor) with counsel selected by the Indemnitor and reasonably satisfactory to the Indemnitee, for so long as the Indemnitor is conducting a good faith and diligent defense. Should the Indemnitor so elect to assume the defense of a Third Party Claim, the Indemnitor will not be liable to the Indemnitee for any legal or other expenses

- 25 -

CONFIDENTIAL PORTION OMITTED AND FILED SEPARATELY WITH THE COMMISSION

subsequently incurred by the Indemnitee in connection with the defense thereof; provided, that if under applicable standards of professional conduct a conflict of interest exists between the Indemnitor and the Indemnitee in respect of such claim, such Indemnitee shall have the right to employ separate counsel (which shall be reasonably satisfactory to the Indemnitor) to represent such Indemnitee with respect to the matters as to which a conflict of interest exists and in that event the reasonable fees and expenses of such separate counsel shall be paid by such Indemnitor; provided, further, that the Indemnitor shall only be responsible for the reasonable fees and expenses of one separate counsel for such Indemnitee. If the Indemnitor assumes the defense of any Third Party Claim, the Indemnitee shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnitor. If the Indemnitor assumes the defense of any Third Party Claim, the Indemnitor will promptly supply to the Indemnitee copies of all correspondence and documents relating to or in connection with such Third Party Claim and keep the Indemnitee informed of developments relating to or in connection with such Third Party Claim, as may be reasonably requested by the Indemnitee (including, without limitation, providing to the Indemnitee on reasonable request updates and summaries as to the status thereof). If the Indemnitor chooses to defend a Third Party Claim, all Indemnitees shall reasonably cooperate with the Indemnitor in the defense thereof (such cooperation to be at the expense, including reasonable legal fees and expenses, of the Indemnitor). If the Indemnitor does not elect to assume control of the defense of any Third Party Claim within the one hundred twenty (120) day period set forth above, or if such good faith and diligent defense is not being or ceases to be conducted by the Indemnitor, the Indemnitee shall have the right, at the expense of the Indemnitor, after three (3) Business Days notice to the Indemnitor of its intent to do so, to undertake the defense of the Third Party Claim for the account of the Indemnitor (with counsel selected by the Indemnitee), and to compromise or settle such Third Party Claim, exercising reasonable business judgment.

(c) If the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee for a Third Party Claim, the Indemnitee will agree to any settlement, compromise or discharge of such Third Party Claim that the Indemnitor may recommend that by its terms obligates the Indemnitor to pay the full amount of Losses (whether through settlement or otherwise) in connection with such Third Party Claim and unconditionally and irrevocably releases the Indemnitee completely from all liability in connection with such Third Party Claim; provided, however, that, without the Indemnitee’s prior written consent, the Indemnitor shall not consent to any settlement, compromise or discharge (including the consent to entry of any judgment), and the Indemnitee may refuse in good faith to agree to any such settlement, compromise or discharge, that provides for injunctive or other nonmonetary relief affecting the Indemnitee. If the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee for a Third Party Claim, the Indemnitee shall not (unless required by law) admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnitor’s prior written consent (which consent shall not be unreasonably withheld).

8.4 Insurance Proceeds. Any indemnification hereunder shall be made net of any insurance proceeds recovered by the Indemnitee (it being understood that an Indemnitee may simultaneously pursue an insurance claim and a claim for indemnification hereunder); provided, however, that if, following the payment to the Indemnitee of any amount under this Article 8, such Indemnitee recovers any insurance proceeds in respect of the claim for which such indemnification payment was made, the Indemnitee shall promptly pay an amount equal to the amount of such proceeds (but not exceeding the amount of such indemnification payment) to the indemnifying Party.

ARTICLE 9

TERM AND TERMINATION

9.1 Term.

(a) Except as set forth in Section 11.13, unless earlier terminated by mutual agreement of the Parties in writing or pursuant to the provisions of this Article 9, this Agreement will continue in full force and effect on a country-by-country and Licensed Product-by-Licensed Product basis until the obligation to pay Royalties with respect to the sale of a Licensed Product in such country expires (the “Term”).

(b) On a country-by-country basis and on a Licensed Product-by-Licensed Product basis, upon the scheduled expiration (as contemplated in Section 5.2) of the obligation to pay Royalties with respect to the sale of such Licensed Product in such country, the licenses granted hereunder shall become fully paid up, royalty-free, perpetual and irrevocable and the exclusivity restrictions pursuant to Section 2.3 with respect to such country shall no longer be applicable.

9.2 Voluntary Termination by Adolor. Notwithstanding any other provision herein, Adolor may terminate this Agreement on a country-by-country basis and/or Licensed Product-by-Licensed Product basis or in its entirety at any time upon one hundred twenty (120) days advance written notice to EpiCept.

9.3 Material Breach. Upon a material breach of this Agreement by Adolor on the one hand, or EpiCept on the other hand (in such capacity, the “Breaching Party”), the other Party (in such capacity, the “Non-Breaching Party”) may provide written notice (a “Breach Notice”) to the Breaching Party specifying the material breach. If the Breaching Party fails to cure such material breach during the ninety (90) day period (or, if applicable, such longer period, but not to exceed one hundred and eighty (180) days, as would be reasonably necessary for a diligent party to cure such material breach, provided the Breaching Party has commenced and continues its diligent efforts to cure during the initial ninety (90) day period following the date on which the Breach Notice is provided), then the Non-Breaching Party may terminate this Agreement on a Licensed Product-by-Licensed Product and country-by-country basis with respect to the Licensed Product and country to which the breach relates.

relates to a particular Licensed Product (such as, e.g., and without limitation the LidoPAIN^® SP Product) in a particular country within the Territory and EpiCept has elected to terminate this Agreement with respect to such Licensed Product in such country, at EpiCept’s written request, Adolor agrees to and hereby does assign to EpiCept any IND or foreign equivalent thereof for such Licensed Product in such country. By way of example and not by limitation, if Adolor is the Breaching Party and the material breach relates to the LidoPAIN^® SP Product in the United States, at the written request of EpiCept, Adolor agrees to and hereby assigns back to EpiCept IND number 63,666. Notwithstanding the foregoing, the cure period for any failure by Adolor to make Milestone Payments or Royalty payments due hereunder shall be thirty (30) days; provided further, however, that the failure by Adolor to make any such payment shall not be considered a breach to the extent that such payment is the subject of a good faith dispute by Adolor. For the purposes of this Section 9.3, material breach shall mean a breach which materially adversely affects the rights under this Agreement of the other Party with respect to the applicable Licensed Product in the applicable country in the Territory.

9.4 Bankruptcy. Either Party may, subject to the provisions set forth herein, terminate this Agreement by giving the other Party written termination notice if, at any time, the other Party shall: (a) file in any court pursuant to any statute a petition for bankruptcy or insolvency, or for reorganization in bankruptcy, or for an arrangement or for the appointment of a receiver, trustee or administrator of such Party or of its assets; (b) be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof; (c) propose or be a party to any dissolution; or (d) make an assignment for the benefit of its creditors. Should EpiCept become a party to a bankruptcy proceeding and such proceeding is not dismissed within sixty (60) days then, to the extent permitted by law, this Agreement and the licenses granted by EpiCept hereunder shall be adopted by any bankruptcy trustee or relevant Third Party charged with the disposition of same, and shall not be rejected by same, it being the Parties’ intent that, in such event, Adolor and its Affiliates and sublicensees shall be entitled to retain the rights granted to them hereunder by EpiCept.

9.5 Continuing Rights of Sublicensees. Upon any termination of this Agreement, each sublicense previously granted by Adolor, or any of its Affiliates, to any Person that is not an Affiliate of Adolor (each, an “Independent Sublicensee”) shall, at EpiCept’s option, remain in effect and shall become a direct license or sublicense, as the case may be, of such rights by EpiCept to such Independent Sublicensee, subject to the Independent Sublicensee agreeing in writing to assume Adolor’s terms, conditions and obligations to EpiCept under this Agreement as they pertain to the sublicensed rights.

9.6 Effect of Expiration or Termination. Expiration or termination of this Agreement pursuant to this Article 9 shall not (i) relieve a Party hereto of any obligation accruing to such Party prior to such termination, or (ii) result in the waiver of any right or remedy by a Party hereto accruing to such Party prior to such termination.

9.7 Limitation of Liabilities. NOTWITHSTANDING THE FOREGOING, EXCEPT AS MAY BE THE CASE UNDER ARTICLE 8 ABOVE WITH RESPECT TO INDEMNIFICATION FOR THIRD PARTY CLAIMS, NO PARTY WILL BE LIABLE TO ANY OF THE OTHER PARTIES FOR PUNITIVE, EXEMPLARY, SPECIAL, INDIRECT,

EpiCept agrees that Adolor shall have the full right to use the clinical trial data for development, regulatory and commercialization of Licensed Products. Adolor agrees to provide to EpiCept, to the extent that it would not violate the terms of any agreement between Adolor and a third party, in form and format reasonably requested by EpiCept, data generated by Adolor relating to the lidocaine patches manufactured by Corium International, Inc. (“Corium”) which data is necessary for EpiCept’s use of such lidocaine patches in EpiCept’s European clinical trial EPC
