The Development Committee shall establish a program and plan (a “Development Program”) for each Collaboration Product, or for each different indication for which a Collaboration Product is being developed, as applicable, that shall, among other things, (A) set forth a plan for achieving the Target Labeling as approved by the CSC, (B) set forth detailed budgets for the Development Costs to be incurred, for approval by the CSC, (C) in consultation with the Marketing Committee, as appropriate, prescribe the non-clinical and clinical activities, studies and trials to be conducted by the Parties, (D) specify the timing, finalization and reporting of each such activity, study and trial, and (E) otherwise specify all other Development activities to be conducted by the Parties required to obtain Regulatory Approval for the Territory. The Development Committee shall coordinate and manage the Development activities as set forth in the Development Program for each Collaboration Product and if necessary, shall propose amendments to such Development Program for consideration and approval by the CSC.

(ii) The “Marketing Committee,” which shall be responsible for planning, overseeing and implementing the Promotion of Collaboration Products in the Territory, and for overseeing the Commercialization of Collaboration Products in the Territory. The

Marketing Committee shall create an annual plan for approval by the CSC, which shall contain the elements set forth in Annex F attached hereto, a budget for Promotion activities and an allocation of responsibility between Teva and Acorda for the Promotion of each Collaboration Product in the Territory, taking into account the relative strength and capabilities of each Party in the target market (the “Marketing Plan”). In particular, the Marketing Committee shall address issues arising in the context of, and create a plan with a detailed budget for each expense category and an allocation of responsibility between Teva and Acorda for, the Promotion of Collaboration Products to: (A) managed care organizations, pharmacy benefit managers, group purchasing organizations, specialty pharmaceutical organizations, institutional buyers, long-term care facilities, consulting pharmacy entities, governmental entities and other managed care organizations in the Territory (collectively, the “Managed Care Organizations”); and (B) Target Prescribers. The Marketing Committee shall also set the recommended list pricing for Collaboration Products in the Territory and shall establish guidelines for any discount, rebate, price reduction or chargeback programs or policies applicable to Commercialization of Collaboration Products in the Territory.

(iii) The “Compliance Committee,” which shall be responsible for (A) ensuring that all Marketing Materials and Promotion of Collaboration Products comply with applicable laws and regulations of all regulatory authorities, (B) formulating policies regarding Promotional guidelines and grants to Target Prescribers in respect of Collaboration Products in the Territory, and (C) such other related compliance matters as are assigned by the CSC.

(iv) Such other subcommittee(s) within the areas of Development and Promotion as the CSC deems necessary.

(c) Rules of Procedure, Delegation, and Binding Power of CSC.

(i) In addition to the subcommittees to be appointed pursuant to Section 2.1(b), the CSC may prescribe such rules of procedure and may delegate such of its oversight and responsibilities to one or more subcommittees (in each case to be equally represented by the Parties).

(ii) The CSC shall (A) select treatment uses of a Collaboration Product for Development by the Parties under this Agreement, as applicable; (B) approve or disapprove all budget(s) for a Development Program and the Development Costs associated therewith; (C) supervise and coordinate all Development activities of the Development Committee, including, without limitation, re-scheduling non-clinical studies and clinical trials; establishing milestones for the completion of Development Program objectives, including those relating to anticipated filing dates of NDAs, INDs, regulatory filings required to initiate clinical trials, and/or similar regulatory submissions; (D) evaluate the progress of Development Programs; (E) recommend to end the Development of any Collaboration Product; and (F) generally supervise the efforts of each Party to ensure that it exercises commercially reasonable efforts to undertake and complete those portions of a Development Program for which it is responsible.

(iii) All decisions of the CSC within its scope of oversight and made in accordance with this Agreement, shall be binding on the Parties.

(d) Deadlock. In the event that the CSC cannot agree on an issue within its area of oversight or an issue properly referred to it by any subcommittee within twenty (20) Business Days of the initial referral to it (or such longer period as the CSC may agree), the matter shall be deemed a Dispute that the CSC cannot resolve and it shall be resolved in accordance with the Dispute resolution procedure set forth in Section 14.12. Notwithstanding anything contained in this Agreement to the contrary, with regard to any Dispute as to those matters set forth on Annex G attached hereto, the Parties understand and agree that such Disputes shall not be referred to binding arbitration after the above process, but rather, Teva shall have the ultimate decision making authority in respect of each such Dispute, which decision shall be made in good faith taking into account the interests of Acorda under this Agreement.

(e) Further Responsibilities of the CSC.

(i) The CSC shall convene at least four (4) times annually or more frequently as it deems necessary. The location of the meetings shall alternate between each Party’s facilities, or at such locations as the Parties may otherwise agree. Meetings may be held by audio or video teleconference, with the consent of each Party; provided that at least one (1) meeting per calendar year shall be held in person. Special meetings of the CSC may be called on at least fifteen (15) Business Days prior written notice by either of the co-chairpersons. Each Party shall be responsible for all of its own expenses of participating in the CSC.

(ii) Each Party will have one (1) vote on CSC matters, which will be delivered by its co-chairperson. The CSC shall at all times make decisions by unanimous vote of the two (2) co-chairpersons and may act by unanimous written consent in lieu of a meeting. The CSC shall keep a written record of all its proceedings, which record shall be confirmed in writing by the two (2) co-chairpersons.

(iii) The CSC shall manage and oversee (A) all activities of the Development Committee, the Marketing Committee, the Compliance Committee and any other subcommittees formed by the CSC, and (B) the implementation of the Marketing Plans, Development Programs and other plans created by any other subcommittees formed by the CSC.

(iv) During the period of Development of a Collaboration Product, the CSC shall keep the Parties informed of the activities required under the Development Program(s) and each Party shall ensure that the activities of the Development Program(s) assigned to such Party are diligently carried out in due time. The CSC shall establish, periodically review, and modify (as may be necessary and advisable), all draft protocols and draft reports (non-clinical and clinical), draft expert reports, draft summaries and final versions of the same, and the commercial objectives and activities set forth as part of the Development Program(s). In connection therewith, the CSC shall review and evaluate the Development Program for each Collaboration Product, including any proposed amendments thereto submitted by the Development Committee, on a calendar quarter basis. Any changes to a Development Program must be in writing and approved by the CSC pursuant to the provisions hereof.

(v) The CSC shall oversee the planning and Promotion efforts of the Marketing Committee, as well as market support initiatives, overall marketing and brand strategy for each Collaboration Product, and other related Promotion activities in the Territory in

(vi) The CSC shall use its best efforts to timely agree on and approve all Marketing Plans, with the expectation that such approval shall occur no later than sixty (60) Business Days prior to the commencement of each calendar year during the Term of this Agreement. The CSC shall also have final approval, exercisable through its approval of the relevant Marketing Plan, over the allocation of Promotional responsibilities between Teva and Acorda in the Territory with the goal of splitting such responsibilities on a 50/50 basis. The CSC shall be responsible for reviewing and approving the payments to either Party pursuant to Sections 4.2 and 4.3 with respect to Promotion activities.

Section 2.2 Global Strategic Committee.

(a) Without in any manner expanding the rights provided hereunder to Acorda beyond the Territory, the Parties shall, at Teva’s request, promptly form a global strategic committee (the “GSC”) to oversee coordination of the global development and global strategic promotion of Collaboration Products; provided, however, that the GSC will not have oversight over the Development and Promotion of Collaboration Products in the Territory, which shall be within the sole purview of the CSC.

(b) The GSC shall be comprised of an equal number of representatives, not to exceed three (3) representatives, from each of the following parties: Teva, one or more Third Parties authorized by Teva, and Acorda (each, a “GSC Party”), including one (1) co-chairperson appointed by each GSC Party. Each GSC Party may replace any of its representatives at any time, and from time to time, by giving written notice to the other GSC Parties. Each GSC Party must promptly fill any vacancy to the GSC caused by the death, resignation or other incapacity of any of its representatives. Each GSC Party shall be responsible for its own expenses of participating on the GSC.

(c) At its initial meeting, the GSC will, in good faith, promulgate a reasonable meeting schedule and rules of procedure.

Section 2.3 Nature of Obligations Between Parties. Unless otherwise expressly stated, nothing contained in this Agreement may be deemed to make any Party, or member of the CSC or GSC, or any subcommittee formed thereunder, a partner, agent or legal representative of the other Party. No Party, or any member of the CSC or GSC, or any subcommittee formed thereunder, shall have any authority to act for, or to assume any obligation or responsibility on behalf of any other member of such committee, or the other Party.

ARTICLE 3

DEVELOPMENT OF PRODUCTS

Section 3.1 General

(a) The Parties agree (i) unless otherwise set forth to the contrary in this Agreement or as may otherwise be decided by the CSC, to conduct and perform jointly (on a 50/50 basis) the Development Programs for the purpose of furthering the Development of each Collaboration Product, as those programs are promulgated by the Development Committee and approved by the CSC, and (ii) regardless of which Party is responsible for the performance of any specific Development activity, to take into account, in good faith, the comments, if any, made by the other Party in respect of such activity.

(b) The Party that is responsible for the performance of a specific activity under a Development Program shall use commercially reasonable efforts to complete such activity within the time frame set forth in the Development Program and to ensure that the actual costs of such activity do not exceed the budgeted costs therein as approved by the CSC. If the responsible Party believes that the actual costs in relation to a particular activity will exceed the budgeted costs, that Party shall promptly notify the CSC and must obtain the CSC’s approval in order to incur such excess costs, which approval shall not be unreasonably withheld, conditioned or delayed. The Parties agree that all costs incurred and reported in the Development, manufacture, Commercialization and Promotion of Collaboration Products for the Territory shall reflect each Party’s actual costs of performing such activities and shall not include any additional cost xxxx-up by, or overhead of, such Party.

(c) The Parties agree to Develop the Collaboration Products as selected by the CSC diligently and collaboratively, using good pharmaceutical practices with the goal of maximization of profits from the sale of Collaboration Products in the Territory. Each Party shall use reasonable and diligent efforts consistent with good pharmaceutical practices to perform the tasks assigned to it under the Development Program. Subject to confidentiality, non-disclosure and similar undertakings, each Party shall provide the CSC, or any duly authorized representatives of the CSC, with reasonable access during regular business hours to all of its records and documents that are specific to the Development of any Collaboration Product that the CSC may reasonably require in order to perform its obligations hereunder. In addition, each Party shall report to the CSC in writing, in a format and on a schedule established by the CSC, summarizing the results of such Party’s Development work and efforts and identifying any significant matters, developments or issues.

(d) Upon successful completion of a Development Program, or earlier as reasonably determined by Teva, Teva, in consultation with Acorda, shall use commercially reasonable efforts to seek Regulatory Approval for the relevant Collaboration Product in the Territory. As between Teva and Acorda, Teva shall be the sole owner of all Regulatory Approvals (as well as applications, including without limitation, INDs and NDAs) (all of which shall be applied for in the name of Teva or one of its Affiliates) received with respect to all Collaboration Products. Teva shall also be responsible for and perform all activities relating to the maintenance of such Regulatory Approvals in the Territory during the Term of this Agreement. With respect to Teva seeking and maintaining Regulatory Approval for a Collaboration Product in the Territory, Teva shall provide copies to Acorda of any proposed filings and material correspondence related thereto in sufficient time for Acorda to provide its comments, if any, prior to submission. Teva shall consider Acorda’s comments in good faith and shall, to the extent practicable, otherwise consult with Acorda in such activities. If there are any

meetings with the FDA concerning such Regulatory Approvals, Teva shall, to the extent practicable, provide sufficient notice to Acorda to enable Acorda to attend such meetings.

(e) The Parties understand and agree to conduct all pre-clinical and clinical research and studies involving Collaboration Products in accordance with then-current good laboratory practices and good clinical practices, as specified by the applicable laws and regulations in the country where such research and studies are performed.

Section 3.2 Development of the Lead Indication.

(a) Acorda shall perform all activities related to the Development of a Collaboration Product as an adjunct therapy for the treatment of epilepsy (the “Lead Indication”) as required to obtain and maintain (for and in the name of Teva) the necessary Regulatory Approvals in the Territory, all in accordance with the Development Program for the Lead Indication and the provisions of this Section 3.2. Teva will have the right to participate and be involved actively in all such Development activities undertaken by Acorda.

(b) Without limiting any of Acorda’s other obligations hereunder, and notwithstanding any other provision of this Agreement to the contrary, Acorda shall bear [***] of the Development Costs, as incurred, for the Next Trial and the carcinogenicity study to be conducted for a Collaboration Product for the Lead Indication, each as more particularly described in Annex H attached hereto, and any pre-clinical studies, drug interaction studies or other testing that the FDA requires or the CSC desires to conduct for a Collaboration Product for the Lead Indication. Teva shall supply Collaboration Product [***] for conducting the Next Trial. Acorda shall use commercially reasonable efforts to complete the Next Trial by the first quarter of 2006, subject to any unexpected delays caused by matters outside of Acorda’s control (such as FDA-required additional studies or delays). [***] of the Development Costs (as approved by the Development Committee or the CSC) expended by Acorda for the carcinogenicity study, or the aforementioned pre-clinical studies, drug interaction or other testing (excluding the Next Trial) for the Collaboration Product for the Lead Indication will be credited against and deducted from the payment due Teva pursuant to Section 4.1(c).

(c) After completion of the Next Trial, if the FDA requires further clinical trials or other studies (in addition to those referred to in Section 3.2(b) hereof) to obtain Regulatory Approval of the Collaboration Product for the Lead Indication in the Territory, then the Parties shall perform such trials and studies only if the CSC desires to perform same. In the event the CSC so desires to perform such additional trials or studies, then the Parties shall share the Development Costs thereof on a 50/50 basis in accordance with the applicable Development Program. If on the other hand the CSC does not desire to perform same, such lack of desire shall be considered a decision by the CSC and, accordingly, not subject to the provisions of Section 2.1(d) hereof.

Section 3.3 Development of Secondary Indications.

(a) The CSC shall, promptly after the Effective Date, decide whether it is commercially desirable to develop a Collaboration Product for use in the treatment of bipolar

disorder or neuropathic pain (such indications, the “Secondary Indications”), in addition to the Lead Indication. Following the CSC’s decision, the Development Committee (with the approval of the CSC) shall establish a human clinical trial to be implemented by the Parties for the chosen indication (the “Proof of Concept Trial”), which the Parties agree shall be tailored in scope and size to provide only the necessary information to determine whether such Collaboration Product achieves the proof of concept criteria established by the Development Committee and approved by the CSC for such indication. Such clinical trial shall be conducted by the Parties contemporaneously, or as close in time as is commercially practical, with the Next Trial for the Lead Indication (as discussed in Section 3.2(b) above). The Parties shall use commercially reasonable efforts to complete such Proof of Concept Trial by the first quarter of 2006, subject to any unexpected delays caused by matters outside of Acorda’s control (such as FDA-required additional studies or delays). The costs of such Proof of Concept Trial shall be deemed Development Costs, which the Parties shall share on a 50/50 basis.

(b) The Secondary Indication not chosen by the CSC to be the subject of the Proof of Concept Trial under Section 3.3(a), will be subject to further Development by the Parties, if at all, only as permitted in, and in accordance with, the provisions of Section 3.5.

(c) Within sixty (60) Business Days of the code opening of the Proof of Concept Trial, the CSC shall decide whether it is commercially desirable to further pursue the Development of the Collaboration Product for the applicable indication. If the CSC timely decides to pursue such further Development, then the Collaboration Product will be Developed for such indication pursuant to the terms and conditions of this Agreement under a Development Program to obtain and maintain the necessary Regulatory Approvals in the Territory, and such Development shall be funded by the Parties on a 50/50 basis and overseen by the CSC.

(d) Notwithstanding anything contained herein to the contrary, if the CSC does not choose within sixty (60) Business Days of the code opening of the Proof of Concept Trial to further pursue the Development of the Collaboration Product for either or both of the Secondary Indications, then either Party may conduct the further development of the Collaboration Product for such indication as an Independent Party only as permitted in, and in accordance with, the provisions of Section 3.5 applicable to Independent Development.

Section 3.4 Development of a Multiple Sclerosis Indication.

(a) Except as expressly provided in this Section 3.4, and for the avoidance of doubt, the Development, Commercialization, Promotion and sale of a Collaboration Product for the treatment of Multiple Sclerosis is excluded from the scope of this Agreement. Teva and/or its Affiliates may develop, promote, market, sell and commercialize a product containing the Compound specifically to treat Multiple Sclerosis (the “MS Product”). In the event that Teva and/or any of its Affiliates elects to undertake such activities with respect to the MS Product in the Territory, alone rather than in collaboration with a Third Party, it shall provide Acorda with written notice thereof [prior to commencing Phase III trials on the MS Product]. Following such notice, the Parties shall meet (at a time and place mutually convenient) to discuss the impact, if any, that any potential off-label sales of the MS Product in the Territory or of Collaboration Products in the Territory may have on the sales of the other and the resulting impact on Copromotion Profits yielded therefrom or Teva sales of the MS Product in the Territory,

respectively. The Parties shall then negotiate in good faith and agree on an amendment to this Agreement to provide for an annual adjustment and reconciliation, based on a reasonable and mutually agreed procedure, for addressing in a fair manner any such impact on Copromotion Profits, and/or on Teva’s sales of MS Products, based on any such off-label sales, with the understanding that the Parties will employ, in such procedure, the best available resources for determining actual sales of Collaboration Products and MS Products, respectively, for uses for treatment of Multiple Sclerosis, as distinct from sales for all other uses developed hereunder, and with the further understanding that such adjustment or reconciliation for the first year of sales of the MS Product, after regulatory approval in the Territory of such product, would necessarily involve an agreed approximation of expected sales, with a reconciliation after the end of such year, based on actual results from such year (as determined using such available resources). If the Parties are unable to reach agreement on such amendment within sixty (60) Business Days, of Acorda’s receipt of Teva’s notice, the matter shall be resolved pursuant to Section 14.12.

(b) Further, notwithstanding the foregoing, if Teva desires to license a Third Party to develop and commercialize an MS Product (alone or in collaboration with Teva) in the Territory, then prior to entering into any bona fide negotiations with such a Third Party, Teva shall provide written notice thereof to Acorda. If within sixty (60) Business Days of Acorda’s receipt of Teva’s notice under this subsection (b), Acorda provides written notification to Teva of its desire to Develop a Collaboration Product for the treatment of Multiple Sclerosis under this Agreement with Teva, then the Collaboration Product will be Developed for Multiple Sclerosis pursuant to the terms and conditions of this Agreement under a Development Program to obtain and maintain the necessary Regulatory Approvals in the Territory, and such Development shall be funded by the Parties on a 50/50 basis and overseen by the CSC in accordance with the applicable provisions of this Agreement. If Acorda declines to pursue such Development, or does not respond to such Teva notice, by the end of such sixty (60) Business Day period, Teva shall no longer have any obligation under this Agreement or otherwise to further negotiate or proceed with Acorda with respect to the Development of a Collaboration Product for the treatment of Multiple Sclerosis and shall thereafter be free to develop, commercialize, promote and sell the Compound for the treatment of Multiple Sclerosis in the Territory outside the scope of this Agreement, itself or with any Third Party.

(c) For the avoidance of doubt, Acorda has no rights whatsoever under this Agreement or otherwise with respect to the Compound for the treatment of Multiple Sclerosis outside the Territory (including, without limitation, the right to receive royalties in respect thereof, unless a Collaboration Product is Developed under this Agreement for treatment of Multiple Sclerosis in the Territory, and Section 4.2(a)(iii) applies to Teva’s (or its Affiliate’s or licensee’s) use of the results of such Development work outside the Territory). Neither Party has any obligation whatsoever to collaborate with the other to develop the Compound for a Multiple Sclerosis indication outside the Territory and Teva is free to collaborate at any time with a Third Party to develop, or to develop on its own, the Compound for the treatment of Multiple Sclerosis outside the Territory. For clarity, as used in this section, “Collaboration Product (or Compound) for the treatment of Multiple Sclerosis” means a Collaboration Product (or Compound) or an MS Product with Multiple Sclerosis as a labeled treatment indication, and any use of a Collaboration Product (or Compound) to treat any secondary condition associated with Multiple Sclerosis (e.g., neuropathic pain or muscle weakness) that is not already being Developed pursuant to Section

3.3, will be deemed a Proposed Use, subject to the provisions of Section 3.5 and not the provisions of this Section 3.4.

Section 3.5 Development of Other Indications and/or Dosage Forms.

(a) At any time after the Effective Date, either Party may make a written proposal to the CSC regarding the Development of a Collaboration Product for any indication, and/or dosage form, and/or other formulation (such as an extended-release formulation), that is not then being Developed or Commercialized, for Commercialization within the Territory under this Agreement (a “Proposed Use”), including any Secondary Indication not selected or pursued under Section 3.3, but excluding a Multiple Sclerosis indication, which may only be proposed by Teva to Acorda in accordance with Section 3.4 above. Such proposal shall include (i) any data and other information in its possession that may be relevant to the use of a Collaboration Product for such Proposed Use, (ii) a reasonably detailed outline for the major Development activities required to obtain Regulatory Approval for such Proposed Use in the Territory, including a timeline for performing such activities, (iii) an estimated budget for the expected Development Costs, Copromotion Expenses, Production Costs and Distribution Costs for the Development and Copromotion of a Collaboration Product for such Proposed Use, (iv) an appropriate market analysis of such Proposed Use, including, without limitation, expected market size and competitive analysis, and (v) preliminary sales forecasts for the Collaboration Product for such Proposed Use. Thereafter, the CSC shall meet in order to review such proposal.

(b) The CSC will have ninety (90) Business Days, or such longer period as the Parties may mutually agree, from receipt of such proposal (the “Additional Indication Review Period”) to decide whether the Development of a Collaboration Product for such Proposed Use is commercially desirable to both Parties. If such proposal is accepted by the CSC, then the Parties will jointly Develop the appropriate Collaboration Product for such Proposed Use pursuant to the terms and conditions of this Agreement, including establishing a Development Program for such Proposed Use by the CSC and funding by the Parties on a 50/50 basis. If the CSC rejects a proposal for a Proposed Use, or does not make a decision within the applicable Additional Indication Review Period, a Collaboration Product for such Proposed Use may be developed independently by either Party (an “Independent Party”), at the Independent Party’s sole cost and expense, but otherwise subject to the applicable terms and conditions of this Agreement (such independent development for such Proposed Use, “Independent Development”), by providing written notice thereof to the other Party. Notwithstanding the foregoing, if Acorda decides to pursue such Independent Development and provides written notice thereof to Teva, Acorda shall not be permitted to engage in any such Independent Development without Teva’s prior written consent, which shall not be unreasonably withheld or delayed. Teva shall include in any such written consent a determination as to whether it has the intention and commitment to manufacture and supply the Collaboration Product for such Proposed Use to Acorda, in the event that Teva does not exercise the Re-Engagement Option for such Proposed Use in accordance with Section 3.5(c). If Teva determines that it shall not manufacture and supply to Acorda the Collaboration Product for such Proposed Use hereunder, Acorda shall be prohibited from undertaking Independent Development for such Proposed Use. Upon receipt of Teva’s written consent, Acorda may commence such Independent Development and shall provide Teva with written notice of the commencement thereof. Notwithstanding the foregoing, if, at any time during Independent Development of a Collaboration Product for a

Proposed Use, Teva determines, in its reasonable business and/or scientific judgment, that the continuation of such Independent Development activities could reasonably be anticipated to have a material detrimental impact upon Teva, the Compound, any Collaboration Product or any of Teva’s other rights or obligations, than such Independent Development activities shall cease. If Teva makes such a determination, it shall reimburse Acorda for the actual direct out-of-pocket costs incurred by Acorda as a result of such Independent Development activities, but such reimbursement shall not include the payment of any interest thereon.

(c) If a Party undertakes the Independent Development of a Collaboration Product for a Proposed Use pursuant to Section 3.5(b), then such Independent Party, with respect to such Proposed Use, shall: (i) provide the CSC with a summary of its development plans and accommodate any reasonable comments of the CSC, to ensure that such development efforts are coordinated with and not contrary to the joint Development efforts of the Parties on Collaboration Products; (ii) provide the other Party (the “Non-Participating Party” as to such development) with quarterly written summaries of the data and results of such development efforts as to such Proposed Use; and (iii) provide written notices to the Non-Participating Party promptly after completion of each stage, including the proof of concept clinical trial, the first Pivotal Trial and the second Pivotal Trial, for the relevant Proposed Use of a Collaboration Product. Such Non-Participating Party shall have the exclusive option to re-engage after the completion of each stage in the joint Development and Promotion of the Collaboration Product for such Proposed Use (a “Re-Engagement Option”), which shall be exercisable by the Non-Participating Party, by notifying the Independent Party in writing of its election, promptly after the completion of each stage for such Proposed Use and before the Independent Party’s receipt of an Approvable Letter for such Proposed Use, or, absent such Approvable Letter, before the Independent Party’s receipt of Regulatory Approval in the Territory for such Proposed Use of a Collaboration Product. Exercise of a Re-Engagement Option shall be subject to the following terms and conditions:

(i) Within fifteen (15) Business Days of exercise of the Re-Engagement Option as to a particular Proposed Use, the Non-Participating Party shall pay to the Independent Party an amount (the “Re-Engagement Fee”) equal to the sum of: (A) [***] of all Independent Development Costs incurred by the Independent Party through the date of payment (the “Development Share”), plus (B) the following additional amount, as applicable: (1) if the Non-Participating Party exercises the Re-Engagement Option after the completion of the proof of concept clinical trial but before the completion of the first Pivotal Trial for the relevant Proposed Use, a risk factor xxxx-up of an additional [***] of such Development Share; (2) if the Non-Participating Party exercises the Re-Engagement Option after completion of the first Pivotal Trial but before the completion of the second Pivotal Trial for the relevant Proposed Use, a risk factor xxxx-up of an additional [***] of such Development Share; or (3) if the Non-Participating Party exercises the Re-Engagement Option after the completion of the second Pivotal Trial but before the Independent Party’s receipt of an Approvable Letter for such Proposed Use, or, absent such Approvable Letter, before the Independent Party’s receipt of Regulatory Approval in the Territory for such Proposed Use, a risk factor xxxx-up of [***] of such Development Share; provided that, the Non-Participating Party may, at its discretion, satisfy any such payment due under subsection 3.5(c)(i)(B)(3) in two equal quarterly installments, each of which shall be due on the last day of the following two (2) calendar quarters, respectively, after exercise of the Re-Engagement

Option. As used in this Section, the phrase “completion of” a particular Clinical Trial means completion of conducting the trial, analyzing all data and results of the trial, preparing the final and complete report of such analyzed data, and delivering all such data, analysis and report to the Non-Participating Party.

(ii) Effective upon the exercise of the Re-Engagement Option and satisfaction by the Non-Participating Party of the payment conditions set forth under, and in accordance with, Section 3.5(c)(i) above, the relevant Proposed Use for the appropriate Collaboration Product will be Developed and Promoted by the Parties jointly pursuant to the terms and conditions of this Agreement, which shall include establishing a Development Program for such Proposed Use by the CSC for such Collaboration Product and funding of any Development and Promotion activities by the Parties for such Proposed Use on a 50/50 basis, and the Independent Development of such Proposed Use shall terminate. The Independent Party that had been conducting Independent Development of such Proposed Use shall disclose to the Non-Participating Party all data and results of such development.

(iii) The Parties will share, on a 50/50 basis, any Development Costs that are incurred by either Party following the date of exercise of the Re-Engagement Option, in accordance with a Development Program approved by the CSC, for the Proposed Use of such Collaboration Product (which shall include any such costs of the Independent Party that were committed but not yet incurred under its development of such Proposed Use).

(iv) If the Non-Participating Party does not exercise the Re-Engagement Option prior to the Independent Party’s receipt of an Approvable Letter in respect of the relevant Proposed Use of the appropriate Collaboration Product, or, absent such Approvable Letter, before the Independent Party’s receipt of Regulatory Approval in the Territory for such Proposed Use, then the Non-Participating Party shall be barred from re-engaging in the joint Development and Promotion of the Collaboration Product for such Proposed Use, and the Independent Party shall thereafter be entitled to commercialize, promote and sell such Collaboration Product (in the Territory only, in the case in which Acorda is the Independent Party), independently at its own cost and expense, subject to the following:

(1) Promptly after receipt of such Approvable Letter or Regulatory Approval (as applicable) in the Territory for the Independent Use, Teva and Acorda shall meet and discuss in good faith and agree on an amendment to the Agreement to provide for an annual adjustment, based on a reasonable and mutually agreed procedure, to the sharing of the Copromotion Profits such that the Independent Party (as to such Independent Use) shall receive [***] of the Copromotion Profits resulting from its commercialization and promotion activities with respect to sales of the applicable Collaboration Product in the Territory for the Independent Use, with the understanding that the Parties will employ, in such procedure, the best available resources for determining actual sales of Collaboration Product for such Independent Use, as distinct from sales for uses that are Developed jointly by the Parties hereunder, and with the further understanding that such adjustment for the first year of sales of the Collaboration Product for the Independent Use after Regulatory Approval would necessarily involve an agreed approximation of expected sales, with a reconciliation after the end of such year, based on actual results from such year (as determined using such available resources).

(2) In addition, if the Non-Participating Party is Teva, then Teva or its designee will have the right to be the exclusive manufacturer and supplier of the subject Collaboration Product for the Independent Use, and the Parties shall enter into a detailed manufacturing, supply and license agreement, to be negotiated in good faith, which agreement shall incorporate the applicable terms and conditions of this Agreement, and where the supply of the Collaboration Product for such Independent Use shall be on commercially reasonable terms typical for similar Third Party manufacturing and supply agreements.

Section 3.6 Option Studies. The Parties may, from time to time, consider whether to undertake any particular Option Study proposed by either Party with respect to a Collaboration Product for the Lead Indication. For the purposes of this provision, an “Option Study” shall mean a Phase IV human clinical trial initiated after receipt of initial Regulatory Approval in the Territory. If, within ninety (90) days of any such Option Study proposal by a Party, (i) the Parties consider such proposed Option Study to be commercially viable, then such Option Study shall be performed under this Agreement, and it shall be funded by the Parties on a 50/50 basis, or (ii) either Party does not approve of, or wish to undertake such proposal, then the other Party may, upon written notice to the other Party, undertake such Option Study at its sole cost and expense; provided that, notwithstanding the foregoing, if the Option Study is successful, then the Party that undertook the Option Study will be reimbursed for an amount equal to the sum of [***] of all costs and expenses incurred or committed by such Party in connection with conducting such Option Study, plus a risk factor xxxx-up of an additional [***] of the [***] share. For the purposes of this provision an Option Study shall be considered to be successful if the study end points or if the study goals are substantially achieved.

Section 4.4 Mechanics of Reconciliation. The following applies to reconciliation of Copromotion Expenses:

(a) The CSC shall agree on a common cost per Sales Representative, Professional Education Manager, Scientific Manager and Account Manager (each, the “Common Cost Per Sales Representative,” “Common Cost Per Professional Education Manager,” “Common Cost Per Scientific Manager,” and “Common Cost Per Account Manager,” respectively), which cost shall be based upon actual commercially reasonable costs for each such function, and shall be used by the Parties for purposes of preparing the joint profit and loss statements required hereunder and for billing Copromotion Expenses, on a Collaboration Product-by-Collaboration Product basis, and updated annually. For purposes of calculating costs under this Section 4.4(a), each Party shall only allocate those costs that are directly attributable to such functions for Collaboration Products and shall not include costs relating to each respective Party’s other products (i.e., other than Collaboration Products) in such calculation of Copromotion Expenses. To the extent that a cost is attributable to both Collaboration Products and other products of a Party, only that portion of the cost attributable to Collaboration Products shall be included in the calculation. The aforementioned common costs shall, in every year in which determined by the CSC, take into account the factors set forth on Annex D attached hereto.

(i) The Parties’ sales force costs for Promoting Collaboration Products in the applicable period shall be determined by multiplying the Common Cost Per Sales Representative by (A) the number of Sales Representatives that are Detailing one or more Collaboration Products, in accordance with an approved Marketing Plan and their field-based management, on a full-time basis, and (B) a fraction, the numerator of which is the Weighted Average Details and the denominator of which is the total number of Details (as determined by the respective Party’s call reporting system, which shall comply with reporting standards established by the CSC) delivered by the Sales Representatives included in the Weighted Average Details for all Collaboration Products Detailed by such Sales Representatives.

(ii) The Parties’ Professional Education Manager costs for Promoting Collaboration Products in the applicable period, shall be determined by multiplying the Common Cost Per Professional Education Manager by an amount equal to the sum of: (A) the number of Professional Education Managers working with one or more Collaboration Products, in accordance with an approved Marketing Plan and their field-based management, on a full-time

basis, plus (B) that number equal to (1) the number of Professional Education Managers working with one or more Collaboration Products, in accordance with an approved Marketing Plan and their field-based management, on a part-time basis, multiplied by (2) a fraction that is agreed upon annually by the CSC, to reasonably reflect the average percentage of time that such part-time managers dedicate to working with Collaboration Products.

(iii) The Parties’ Scientific Manager costs for Promoting Collaboration Products in the applicable period, shall be determined by multiplying the Common Cost Per Scientific Manager by an amount equal to the sum of: (A) the number of Scientific Managers working with one or more Collaboration Products in accordance with an approved Marketing Plan and their field-based management, on a full-time basis, plus (B) that number equal to (1) the number of Scientific Managers working with one or more Collaboration Products in accordance with an approved Marketing Plan and their field-based management, on a part-time basis, multiplied by (2) a fraction that is agreed upon annually by the CSC, to reasonably reflect the average percentage of time that such part-time managers dedicate to working with Collaboration Products.

(iv) The Parties’ Account Manager costs for Promoting Collaboration Products in the applicable period shall be determined by multiplying the Common Cost Per Account Manager by an amount equal to the sum of: (A) the number of Account Managers working with one or more Collaboration Products in accordance with an approved Marketing Plan and their field-based management, on a full-time basis, plus (B) that number equal to (1) the number of Account Managers working with one or more Collaboration Products in accordance with an approved Marketing Plan and their field-based management, on a part-time basis, multiplied by (2) a fraction that is agreed upon annually by the CSC, to reasonably reflect the average percentage of time that such part-time managers dedicate to working with Collaboration Products.

(b) Each Party shall maintain accurate accounts and records reflecting such Party’s actual Copromotion Expenses and Development Costs, on a Collaboration Product-by-Collaboration Product basis, in sufficient detail to facilitate any reconciliation required hereunder, and with regard to Teva, accounts and records relating to Production Costs, Distribution Costs, Gross Sales and Net Sales on a Collaboration Product-by-Collaboration Product basis. All accounts and records evidencing revenues, deductions, fees, expenses, costs and reconciliations relating to Collaboration Products shall be subject to audit by an independent auditor of recognized national standing selected by the Party requesting such audit, reasonably acceptable to the other Party and subject to the execution of a confidentiality/non-disclosure agreement reasonably acceptable to the other Party; provided, however that: (i) no Party may require more than one such audit in any calendar year; (ii) audits may not be conducted in a manner or at any time that would conflict with the fiscal year end of the Party being audited or

that would fall within any “blackout” periods agreed by the Parties; (iii) twenty (20) Business Days prior notice will be given by the Party requiring the audit to the other Party; (iv) all audits will be completed within a period not to exceed thirty (30) Business Days; (iv) the auditor’s fees and expenses will be for the account of the Party requesting the audit, provided, however, that if it is determined that such Party was underpaid or overpaid by more than five (5%) percent of the amount properly due, then the other Party shall reimburse such Party the fees and expenses of such audit, together with the sum of such underpayment or overpayment plus interest at the rate of twelve (12%) percent per annum or the maximum rate allowed by applicable law, whichever is lower; and (v) the audits shall be conducted in a manner that minimizes any disruption to the audited Party’s business. The Party invoking the audit hereunder shall ensure that any independent auditor performing the audit shall be subject to a confidentiality agreement sufficient to comply with such the confidentiality obligations set forth in Article 10 hereof. The internal expenses of any Party subject to audit will be for such Party’s account and any overage or underpayment will be promptly refunded or paid, as the case may be.

(f) Teva shall prepare and file all sales, income (excluding Acorda income tax filings) and use tax returns and related filings relating to the Promotion and Commercialization of Collaboration Products in the Territory, and will pay all taxes payable for such purposes, which payments shall be considered Quarterly Copromotion Expenses incurred by Teva for the relevant period except to the extent that any such tax payments have already been deducted from Gross Sales in calculating Net Sales.

(g) Any disagreement regarding payment amounts owed to Teva or Acorda shall be submitted to the CSC promptly for resolution.

(h) Each Party shall maintain its financial records relating to this Agreement for the period as follows: (i) a minimum period of five (5) years for all tax return records and (ii) three (3) years for all other financial records, in each case, from the date that such records were created.

(i) All amounts due to Teva and/or Acorda under this Agreement shall be paid by wire transfer to such bank as Teva and/or Acorda, as the case may be, may direct from time to time. All bank expenses incurred by the remitting Party in making such wire transfers will be for its account.

(j) All payments of any amounts pursuant to this Agreement shall be made in USD. To the extent amounts are incurred in a currency other than USD, the applicable amount will be converted into USD on a quarterly basis using as a rate of exchange the arithmetic average of the applicable actual foreign currency exchange rate for the quarter in which the income is received or expense is incurred, as quoted at the closing of each Business Day by the Reuters News Service for the applicable quarter.

(k) All payments of any amounts pursuant to this Agreement must be in compliance with applicable tax withholding obligations. Each Party shall be entitled to withhold any amounts required to be withheld by any applicable law from the amounts payable to the other Party.

(c) Teva hereby grants to Acorda a non-exclusive, worldwide, royalty-free, fully paid-up, perpetual, irrevocable license, with full rights to sublicense, under that portion of the Program Intellectual Property either developed solely by Acorda or jointly by Teva and Acorda to develop, make, have made, use, offer for sale, sell and import, one or more products, excluding, however, any products or service that are directly or indirectly competitive with any of Teva’s, or any of its Affiliates’, products or services (excluding the provisions of this Agreement).

(d) Except as expressly provided in this Agreement (including without limitation Section 9.1), no right, title or interest is provided, licensed, granted or otherwise conveyed by one Party to the other Party with respect to such Party’s know-how, patent rights, trade secrets or any other intellectual property right, owned, controlled, licensed or developed by such Party.

Section 8.2 Exchange of Information. From time to time during the Term of this Agreement, upon the request of Acorda, Teva shall, subject to all legal requirements and contractual obligations, promptly disclose to Acorda any and all of its Know-How and Patent Rights as necessary or reasonably useful for Acorda to perform its obligations and exercise its rights under this Agreement. From time to time during the Term of this Agreement, upon the request of Teva, Acorda shall, subject to all legal requirements and contractual obligations, promptly disclose to Teva any and all of the Acorda Background Technology as necessary or reasonably useful for Teva to perform its obligations and exercise its rights under this Agreement. Further, from time to time during the Term of this Agreement, as provided herein and at any time upon the request of the other Party, each Party shall disclose to the other Party the results, data and information resulting from such Party’s Development and Promotion efforts.

Section 8.3 Right of First Negotiation for Additional Compounds. Subject to the terms and conditions of this Agreement, during the Term of this Agreement, each Party hereby grants to the other Party the following right of first negotiation to obtain from such Party the co-exclusive right, together with the Party and its Affiliates, to develop and promote in the Territory

any analogues, derivatives or metabolites based upon the Compound, or any other valproic acid related compound similar to the Compound that such Party has or may hereafter acquire (each, an “Additional Compound”). If a Party has or obtains rights to any Additional Compound and intends to develop or license such compound in the Territory, then such Party shall promptly issue to the other Party a written notice to this effect and provide to such other Party all material information in its possession relating to the development or commercialization of such compound. If the other Party notifies such Party within thirty (30) Business Days after receiving the notice and all such information that it desires to negotiate an agreement to jointly develop and promote such Additional Compound, then Teva and Acorda shall in good faith proceed to negotiate such an agreement over the period up to sixty (60) Business Days from the date of such other Party’s timely notice. If the Parties are not able to agree upon the terms of a development and promotion agreement (including terms respecting adequate financial resources and security) within the aforementioned sixty (60) Business Day negotiation period (or such longer period as may be agreed by the Parties), or if such other Party does not provide notice to the Party of its interest in such Additional Compound within the aforementioned thirty (30) Business Day notice period, then such right of first negotiation as to such compound shall expire and be of no further force or effect. Notwithstanding anything to the contrary set forth in this Section 8.3, neither Party shall have a right of first negotiation for, nor shall either Party otherwise be entitled to receive any rights from the other Party to develop and/or promote, any Additional Compound for the Multiple Sclerosis indication or any generic version of any Collaboration Product.

ARTICLE 9

INTELLECTUAL PROPERTY

Section 9.1 Ownership Rights. Regardless of whether developed solely by Teva or Acorda, or jointly by Teva and Acorda, or on the behalf of either of them, Teva, or its designee, shall own all right, title and interest in and to all Program Intellectual Property. Any and all patents issued or issuable in respect of such Program Intellectual Property shall be issued in the name of Teva or its designee. Acorda hereby assigns and transfers to Teva all of its right, title and interest in and to all Program Intellectual Property and agrees, as may reasonably be requested by Teva, to perform those acts necessary to confer upon and to perfect Teva’s full and complete ownership rights in and to the Program Intellectual Property as contemplated under this Section 9.1, including, without limitation, freely sharing with Teva any and all information related to Acorda’s development of any Collaboration Product. In furtherance of the foregoing, at any time during or after the Term of this Agreement, Acorda shall (a) preserve the confidentiality of all Program Intellectual Property that may form the basis of a patent application and (b) at Teva’s sole cost, fully support Teva’s efforts to obtain patent protection on such potentially patentable subject matter, including participating in the preparation, execution and filing of appropriate formal documents in national and international patent offices and obtaining the cooperation of the inventors in supporting said patent application. Acorda shall retain the exclusive right, title and interest in and to all Acorda Background Technology, subject only to the license rights granted under this Agreement.

Section 9.2 Intellectual Property Litigation.

(a) Notice of Infringement Claim. If the developing, making, using, selling or importing of Collaboration Products or any other activity performed by the Parties in the Territory under this Agreement results in a claim against a Party for patent infringement or Trademark infringement or for inducing or contributing to patent infringement or trademark infringement of a Third Party’s rights, as applicable (an “Infringement Claim”), the Party first having notice of an Infringement Claim shall, within fifteen (15) days of such notice, provide written notice to the other Party thereof. Such notice to the other Party shall set forth the facts of the Infringement Claim in reasonable detail.

(b) Responsibilities. With respect to any Infringement Claim, the Parties shall attempt to negotiate in good faith a resolution with respect thereto. If the Parties cannot reach an agreeable resolution with the Third Party bringing such Infringement Claim, then (i) Teva will have the sole right and obligation to control the defense of any such Infringement Claim that relates to the Patent Rights, the Know-How, the Trademarks, or the Program Intellectual Property, including any practice or use thereof; and (ii) Acorda will have the sole right and obligation to control the defense of any such Infringement Claim that relates to the Acorda Background Technology, all pursuant to and consistent with the terms of this Agreement. The Parties shall share all costs and expenses incurred in connection with any such Infringement Claims on a 50/50 basis. The controlling Party will have the right, after consultation with the other Party, to choose legal counsel to represent the Parties in such Infringement Claim and each of Teva and Acorda will waive any conflict of interest that may arise from one (1) attorney or firm representing both Parties with respect to such Infringement Claim. The Party not controlling the defense will have the right, at its sole cost and expense (without any right of reimbursement) to retain its own counsel to monitor any such proceeding. Each Party shall keep the other Party continually informed of all significant matters relating to all Infringement Claims.

Section 9.3 Infringement Claims Against Third Parties.

(a) Protection Against Infringement. Each Party agrees to take reasonable actions to protect the Trademarks, Patent Rights, Know-How, Acorda Background Technology, Program Intellectual Property and any related technology from infringement and from unauthorized possession or use by Third Parties, as provided in this Section 9.3.

(b) Notice of Infringement By Third Party. If any Trademark, Know-How, Patent Right, Acorda Background Technology or Program Intellectual Property under this Agreement is infringed or misappropriated or if such infringement or misappropriation is threatened, as the case may be, by a Third Party in the Territory during the Term of this Agreement (each, a “Third Party Infringement”), the Party to this Agreement first having knowledge of such Third Party Infringement, shall promptly notify the other Party in writing. The notice shall set forth, in reasonable detail, the facts of such Third Party Infringement. Teva shall have the primary right, but not the obligation, to institute, prosecute, and control any action or proceeding, with counsel of its choice, with respect to Third Party Infringement of Trademarks or Program Intellectual Property, and Acorda shall have the right to fully participate in any such action. If Teva chooses not to institute an action, Acorda shall then have the right, but not the obligation, to commence, prosecute, and control the action, with counsel of its choice, subject to the right of reasonable participation of Teva. Any Third Party Infringement of any Know-How or Patent Right will be solely instituted, prosecuted and controlled, if at all, by Teva,

subject to the right of reasonable participation of Acorda. Third Party Infringement of any Acorda Background Technology or Acorda trademark or logo will be solely instituted, prosecuted and controlled, if at all, by Acorda, subject to the reasonable participation of Teva. The parties shall bear all costs and expenses, and retain any amounts received or payable, as a result of any of the foregoing actions or proceedings on a 50/50 basis. The Parties will use their good faith reasonable efforts to consult each other on the costs associated therewith. For clarity, if a Party’s intellectual property rights are infringed by an activity that does not involved making, using, importing, offering for sale or selling a product containing the Compound, such Party shall have the sole right to enforce its intellectual property against such infringement, at such Party’s sole expense, and it shall retain any and all recovery from such enforcement

(c) Party’s Failure to Institute, Prosecute and Control. If either party fails to institute, prosecute and control such action or prosecution of Third Party Infringement of Trademarks or Program Intellectual Property within a period of one hundred twenty (120) Business Days after receiving notice of such Third Party Infringement, then the other Party shall have the right to do so at its own expense; provided however, that such party shall first obtain the other’s consent, not to be unreasonably withheld or delayed, to institute actions to terminate or otherwise prevent continuation of such infringement. If a Party so consents, it agrees to be joined as a party plaintiff in such action, and such Party has the right, at its own expense, to be represented in any such action by counsel of its own choice. Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any amounts received as a result of such litigation instituted by a Party under this Section 9.3(c), after reimbursement of one hundred (100%) of any litigation expenses of each of Party (including the costs and expenses incurred by a Party in providing reasonable assistance to the other), will be retained solely by the Party instituting the action.

(d) Invalidity Claims Against Intellectual Property. Each Party shall promptly notify the other of any events relating to any challenges or threatened challenges to the validity or enforceability of the Trademarks, Know-How, Patent Rights, Acorda Background Technology or Program Intellectual Property.

Section 9.4 Prosecution and Maintenance of Patents. Teva shall, at its sole cost and expense, have the exclusive right and responsibility to prepare, file, prosecute and maintain all Patent Rights, and any patents and related applications with respect to Program Intellectual Property that, in Teva’s opinion, are materially useful to the Development, Promotion and/or Commercialization of Collaboration Products in the Territory. Acorda shall, upon Teva’s request, execute such documents and take such other actions as Teva deems necessary for Teva to apply for, secure, and maintain such patents. Teva shall reimburse Acorda for any costs and expenses incurred by Acorda in taking any such actions under this Section 9.4.

Section 9.5 Use of Trademarks. All Collaboration Products shall be Promoted by the Parties in the Territory only under the trademarks, trade names and logos that are selected by the Marketing Committee and approved by the CSC (each, a “Trademark”). Teva shall file and prosecute trademark applications in the Territory for each Trademark (except for the Acorda name and logo); provided that the costs with respect thereto shall be shared by the Parties on a 50/50 basis.

Section 9.6 Marking. Teva shall xxxx each Collaboration Product used or sold by it in accordance with the requirements of the country of manufacture and sale relating to the marking of patented articles. If a Collaboration Product incorporates processes, products or other materials or methods covered by a pending patent application for Patent Rights or Program Intellectual Property, Teva shall xxxx the Collaboration Product with a “patent pending” or similarly appropriate legend.

Section 9.7 Rights to Trademarks.

(a) Except as otherwise provided in this Agreement, all Trademarks are Teva’s sole and exclusive property (except the Acorda name, logo and other Acorda trademarks). Teva hereby grants to Acorda a non-exclusive license to use the Trademarks in the Territory solely in connection with the purposes of this Agreement. The foregoing non-exclusive license shall terminate upon the termination of this Agreement for any reason (whether by expiration of the Term or otherwise) unless otherwise agreed by the Parties.

(b) Acorda hereby grants to Teva a non-exclusive license to use any Acorda name, logo and other Acorda trademarks that are selected and approved as Trademarks in accordance with Section 9.5 solely in connection with the Promotion of Collaboration Products. The foregoing non-exclusive license shall terminate upon the termination of this Agreement for any reason (whether by expiration of the Term or otherwise) unless otherwise agreed by the Parties.

(c) After termination or expiration of this Agreement for any reason, except as otherwise expressly provided in this Agreement, Teva remains the sole and exclusive owner of any Trademarks (which excludes, for clarity, the Acorda name, logo and other Acorda trademarks), and all of same shall be promptly transferred to Teva.

Section 9.8 Settlements. Any Party prosecuting a Third Party Infringement or defending an Infringement Claim has the right to settle any such Third Party Infringement or Infringement Claim without the consent of the other Party; provided, however, that neither Party shall have any right, without the other Party’s express written consent, to settle any such Third Party Infringement or Infringement Claim if such settlement could reasonably be expected to have a material adverse impact upon the other Party’s rights under this Agreement, or in respect of the Compound or any Collaboration Product.

ARTICLE 10

CONFIDENTIALITY

Section 10.1 Confidentiality. Each Party agrees to maintain the confidentiality and secrecy of any information provided to it by, or on behalf of, the other Party under this Agreement, including, without limitation, pursuant to Article 8 hereof (collectively, the “Confidential Information” of the disclosing Party), which may include proprietary, financial, trade secret, technical, know-how, business, marketing, data or other confidential information, such as information relating to the Compound or any Collaboration Product, pricing, facilities, methods, formulae, processes, strategies, corporate initiatives, production efforts or

requirements, operations, income, projections, contractual and business arrangements, personnel data, whether in verbal, written or other tangible form, and expressly includes Patent Rights, Know How, and Program Intellectual Property. Each Party agrees to maintain the confidentiality and secrecy of, and not disclose to any Third Party, the other Party’s Confidential Information using at least the same degree of care that it uses to maintain its own confidential and secret information, but, in any event, never less than a reasonable degree of care. Neither Party shall use the other Party’s Confidential Information for any purpose other than to exercise its rights, and/or fulfill its duties and obligations, under this Agreement. Each Party may, however, disclose the other Party’s Confidential Information to its Affiliates, officers, directors, employees and agents who have need to know or who have access to that Confidential Information in order to exercise its rights under and/or fulfill its duties and obligations under this Agreement or to its existing investors and professional advisors and, with the other party’s written consent, to any bona fide potential investor, acquirer, merger partner or other potential financial partner, in all such cases, subject to the terms and conditions of this Section 10.1; provided that in each case, the Party conveying the other Party’s Confidential Information shall inform each recipient of the confidential nature of such information and shall cause each recipient to receive and hold such information in accordance with the terms of this Agreement. Each Party will also keep in confidence and not disclose to any Third Parties the terms and conditions of this Agreement, except to its existing investors and professional advisors, and, with the written consent of the other party, such consent not to be unreasonably withheld, to any bona fide potential investor, acquirer, merger partner or other potential financial partner; provided further that the Party disclosing such terms and conditions shall inform each recipient of the confidential nature of such information and shall cause each recipient to receive and hold such information as confidential in accordance with the terms of this Agreement. Each Party shall be responsible for any breach of this Section 10.1 by its Affiliates, officers, directors, employees, agents and other persons to whom the other Party’s Confidential Information is disclosed. The above obligations of confidentiality and non-use do not apply to any information received by Teva from Acorda hereunder that Teva owns pursuant to the terms of this Agreement and to information that the receiving Party can demonstrate by competent written evidence:

(a) Is or becomes known to the public through no fault or omission on the part of the receiving Party;

(b) As evidenced by the receiving Party’s written records, was independently developed by or for the receiving Party without any reference to, or reliance upon, the disclosing Party’s Confidential Information;

(c) Is made available to the receiving Party from another source rightfully in possession of the disclosing Party’s Confidential Information and not under an obligation of confidentiality with respect thereto; or

(d) Is disclosed with the prior written approval of the disclosing Party.

Section 10.2 Permitted Disclosure. Notwithstanding anything to the contrary set forth in Section 10.1, the Parties understand and agree that Teva has existing obligations under the Third Party Agreements and Teva shall be permitted to disclose certain Confidential Information to such Persons as, and solely to the extent, required under such Third Party Agreements;

provided that such Persons are bound by obligations of confidentiality that are substantially similar to those set forth in Section 10.1. Further, the recipient Party may disclose certain of the other Party’s Confidential Information, to the extent that such disclosure is required in order to comply with applicable law or pursuant to an order of the government or a court of competent jurisdiction, provided that the recipient Party (a) provides such other Party with adequate prior notice of the required disclosure, (b) cooperates with such other Party’s efforts to protect its Confidential Information with respect to such disclosure and (c) takes all reasonable measures requested by such other Party to challenge or to limit the scope of such required disclosure.

Section 10.3 Confidential Information Upon Termination or Expiration. Each Party agrees that upon the expiration or termination of this Agreement, upon the other Party’s request, such Party shall promptly deliver to the other Party or otherwise dispose of in accordance with the other Party’s directions, the other Party’s Confidential Information. Upon an Indication Termination for a Collaboration Product under Section 12.2(b), each Party shall continue to maintain the other Party’s Confidential Information that relates to the indication, dosage form or use that is the subject of such Indication Termination, if any, in accordance with Section 10.1.

Section 10.4 Privacy. Notwithstanding anything to the contrary, the Parties agree to treat all individually-identifiable health information as confidential in accordance with all applicable federal, state and local laws and regulations governing the privacy of individually-identifiable health information, including the Health Insurance Portability and Accountability Act of 1996, as amended from time to time, and any regulations and guidance promulgated under that Act. The Parties will execute those amendments to this Agreement as are necessary to ensure that the Parties remain in compliance with such laws and regulations.

Section 10.5 Confidentiality Agreement. The confidentiality provisions set out in this Agreement are in addition to, and do not derogate from, the terms of the Confidentiality Agreement; provided, however, to the extent that any discrepancy exists between the Confidentiality Agreement and this Agreement, the confidentiality provisions of this Agreement shall govern.

ARTICLE 11

INDEMNIFICATION; LIMITATION OF LIABILITY; WARRANTY DISCLAIMER

Section 11.1 Indemnification.

(a) A Party (the “Indemnifying Party”) shall defend, indemnify and hold harmless the other Party and its Affiliates and each of their respective officers, directors, employees, representatives, successors and assigns (collectively, the “Indemnified Party”), from and against all losses, liabilities, damage, costs and expenses (including reasonable attorneys’ fees) resulting from any charges, complaints, actions, suits, proceedings, hearings, investigations, claims and demands of Third Parties (collectively, “Claims”), to the extent that the Claim results from: (i) the Indemnifying Party’s negligence or willful misconduct in performing any of its obligations under this Agreement, (ii) a breach by the Indemnifying Party of any of its representations, warranties, covenants or agreements under this Agreement, or (iii)

as to Teva as the Indemnifying Party, any Claim, to the extent directly based upon, and resulting from, Teva’s decision to act under the Agreement in a manner contrary to Acorda’s desires (to the extent Acorda’s desires were reasonable and in good faith) as to a matter for which Teva has, under the terms of the Agreement, the ultimate authority to decide.

(b) In the event the negligence or willful misconduct of Acorda or Teva, as applicable, and/or their respective Affiliates, contribute to any Claims, then Teva or Acorda, respectively, shall be responsible for that portion of such Claim to which its negligence or willful misconduct have contributed.

(c) With respect to Claims that arise, in whole or in part, from the use of any Collaboration Product in the Territory (including Claims that arise with respect to the Development Programs and/or Commercialization of any Collaboration Product) and which Claims do not arise or occur from the events and/or activities described in Sections 11.1(a) or 11.1(b) above, the Parties shall share such Claims on a 50/50 basis as provided in Section 11.2.

(d) The Indemnified Party shall give the Indemnifying Party notice of any Claim upon which the Indemnified Party intends to base an indemnification claim (an “Indemnity Claim”). The Indemnifying Party has the right to control the defense, settlement or disposition of any Indemnity Claim using counsel of its choice and on terms that the Indemnifying Party deems are appropriate, except that the Indemnified Party may, at its own expense, participate in that defense, settlement or disposition using counsel of its own choice. With respect to the defense, settlement or disposition of an Indemnity Claim, the Indemnified Party shall provide the Indemnifying Party with reasonable assistance and cooperation as reasonably requested by the Indemnifying Party. Without limiting the generality of the foregoing, the Indemnifying Party may not cease to defend, settle or otherwise dispose of any Indemnity Claim without the Indemnified Party’s prior written consent, which consent may be unreasonably withheld, if, as a result thereof, the Indemnified Party would become subject to injunctive or other equitable relief or such disposition would otherwise have a material adverse effect on the Indemnified Party.

Section 11.2 Non-Indemnification Eligible Claims. If any Third Party makes any Claim against a Party based on or resulting from the use of a Collaboration Product in the Territory, and such Claim does not arise from any event or activity requiring one Party to indemnify the other under Section 11.1, then the Parties shall promptly meet and determine the best way to defend against, and resolve, such Claim. Unless the Parties agree otherwise, the Parties shall jointly defend the claim, using mutually acceptable counsel, and shall share the costs equally of such defense and of any settlement or amount of damages paid based on such Claim.

Section 11.3 Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER OR ANY OF ITS AFFILIATES FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES (INCLUDING, WITHOUT LIMITATION, LOST PROFITS, BUSINESS OR GOODWILL) SUFFERED OR INCURRED BY SUCH OTHER PARTY OR ITS AFFILIATES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT,

OR OTHERWISE, ARISING OUT OF THIS AGREEMENT. THE FOREGOING SENTENCE SHALL NOT LIMIT THE RIGHTS OR OBLIGATIONS OF EITHER PARTY WITH RESPECT TO INDEMNIFICATION FOR THIRD PARTY CLAIMS UNDER SECTIONS 11.1 AND 11.2 OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 10.

Section 11.4 Disclaimer of Warranty. Except as expressly set forth in this Agreement, nothing in this Agreement may be construed as a warranty or representation by either Party (a) regarding the effectiveness, value, safety or non-toxicity of the Compound or any Collaboration Product, or any information or results provided by either Party pursuant to this Agreement or (b) that any Collaboration Product will obtain Regulatory Approval. Each Party explicitly accepts all of the same as experimental and for development purposes, and without any express or implied warranty from the other Party. EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, EACH PARTY EXPRESSLY DISCLAIMS, WAIVES, RELEASES, AND RENOUNCES ANY WARRANTY, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

ARTICLE 12

TERM AND TERMINATION

Section 12.1 Term. The Term of this Agreement shall commence on the Effective Date and shall continue with respect to all Collaboration Products, unless earlier terminated in accordance with the terms and conditions of this Agreement, until the earlier of (i) the sixth (6th) anniversary of the Effective Date, if the Parties have not achieved a statistically significant primary endpoint (as set forth in the relevant Development Program, established by the Development Committee and approved by the CSC) as accepted by the FDA for the first Pivotal Trial in respect of any Collaboration Product; (ii) six (6) months after the first generic version of any Collaboration Product is launched in the Territory; or (iii) nine (9) years from the Effective Date, if the Parties have not commenced the Promotion and/or Commercialization of any Collaboration Product.

Section 12.2 Termination.

(a) Termination for General Breach. Except as otherwise provided in subsection (b) below, a Party may terminate this Agreement in its entirety if the other Party breaches any material provision of this Agreement and does not fully cure that breach within thirty (30) Business Days after it receives notice thereof from the other party, or, where that breach is not susceptible to cure during the aforementioned thirty (30) Business Day period, such breaching Party does not begin bona fide efforts to cure that breach during such period and thereafter diligently cure that breach to the non-breaching party’s reasonable satisfaction within ninety (90) Business Days after it receives notice of that breach.

(b) Termination of Indications for Breach of Development. Notwithstanding anything to the contrary in this Agreement, if Acorda materially breaches any of its obligations relating to the Development of a Collaboration Product for a particular

indication, use or dosage form, other than the Lead Indication or with regard to the Proof of Concept Trial for the Secondary Indication selected by the Parties for joint Development under this Agreement (which material breach with respect to either or both thereto is subject to the termination provisions of this Agreement), then Teva shall not have the right to terminate this Agreement in its entirety, but rather Teva may give Acorda written notice of such breach under this subsection (b). If Acorda does not fully cure that breach within thirty (30) Business Days after it receives notice thereof or, where that breach is not susceptible to cure during the aforementioned thirty (30) Business Day period, begin bona fide efforts to cure that breach during such period and thereafter diligently cure that breach to Teva’s reasonable satisfaction within ninety (90) Business Days after it receives notice of that breach, then Teva may by written notice terminate Acorda’s rights under the Agreement as to further Development and Promotion and profit participation with respect to the Collaboration Products for the indication, use or dosage form that was the subject of such uncured material breach (the “Indication Termination”). In the event of such Indication Termination by Teva, Acorda will not thereafter be entitled to Develop, Commercialize, Promote or sell any Collaboration Products for any indications, uses or dosage forms that were not then being Developed, Commercialized, Promoted or sold under this Agreement at the time of such Indication Termination, without providing assurances to Teva, acceptable to Teva, that Acorda will be able meet its funding and other obligations under this Agreement with respect to any such future indications, uses or dosage forms. Absent such assurances, this Agreement shall also be deemed terminated as to such indications, uses or dosage forms for Collaboration Products.

(c) Termination for Bankruptcy. Either Party may terminate this Agreement in its entirety, upon written notice, if the other Party ceases to function as a going concern, makes an assignment for the benefit of creditors, files a voluntary petition in bankruptcy, has an involuntary petition in bankruptcy filed against it that is not dismissed within sixty (60) Business Days, admits in writing its inability to pay its debts as they become due or if an encumbrances takes possession, custody or control or a receiver is appointed over substantially all of the property or assets of such other Party. All rights and licenses granted under or pursuant to this Agreement by one Party to the other Party are, for all purposes of Section 365(n) of Title 11, U.S. Code (the “Bankruptcy Code”), licenses of rights to “intellectual property” as defined in the Bankruptcy Code. As a licensee of such rights under this Agreement, a Party shall retain, and may fully exercise, all of its rights and elections under the Bankruptcy Code. If a Bankruptcy Code case is commenced by or against a Party (the “Bankruptcy Party”), and this Agreement is rejected as provided in the Bankruptcy Code, and the Bankruptcy Party elects to retain its rights hereunder as provided in the Bankruptcy Code, then the Bankruptcy Party (in any capacity, including debtor-in-possession) and its successors and assigns (including, without limitation, a Bankruptcy Code trustee) shall take such steps as are necessary to permit the other Party to exercise its rights under this Agreement. All rights, powers and remedies of the non-Bankruptcy Party provided under this provision are in addition to, and not in substitution for, any and all other rights, powers and remedies now or hereafter existing at law or in equity (including, without limitation, the Bankruptcy Code) in the event of any such commencement of a bankruptcy proceeding by or against a Bankruptcy Party.

(d) Unacceptable Change of Control. If there occurs a Change of Control of Acorda, then Acorda shall provide Teva with prompt written notice of same, but, in any event, no later than fifteen (15) days after the effective date of such Change of Control. Teva shall

thereafter have the right, upon written notice provided within sixty (60) Business Days of its receipt of Acorda’s notice of such Change of Control, to terminate this Agreement in its entirety.

(v) Except as otherwise expressly provided in this Agreement, including Section 12.4, and subject to any rights or obligations that have accrued prior to expiration or termination, neither Party shall have any further obligation to the other Party under this Agreement, nor shall any Party be entitled to receive any fees or other payments on account of such termination or expiration; and

(vi) Acorda will cooperate and provide reasonable assistance to Teva, at Teva’s expense, to transition the Detailing of the relevant Collaboration Product(s) currently being Detailed jointly by the Parties to a Detailing effort to be borne solely by Teva.

Re: Fampridine Right of First Negotiation Grant

Dear Xx. Xxxxxx:

This letter shall confirm our agreement regarding a possible collaboration agreement to develop, co-promote and commercialize in the United States (including its possessions and territories), Canada and Mexico (collectively, the “Territory”) all finished pharmaceutical products that contain Acorda’s chemical compound referred to as fampridine (the “Fampridine Agreement”).

Commencing on the date hereof Acorda hereby grants to Teva the exclusive right of first negotiation pursuant to which it shall enter into good faith negotiations exclusively with Teva regarding terms of a possible mutually acceptable Fampridine Agreement. It is understood that neither party is obligated to enter into such a Fampridine Agreement except on terms acceptable to it in its discretion, and that Acorda may determine that the terms proposed by Teva are not as attractive as proceeding on its own (or, as permitted below, with a third party). If the parties are unable to agree upon mutually acceptable terms for the Fampridine Agreement, and Teva has not already provided Acorda with its written notice to terminate such good faith negotiations, then Acorda may terminate the right of first negotiation hereunder upon written notice given to Teva at any time from and after the date sixty (60) days from the last date (the “Trial Completion Date”) on which Acorda has delivered to Teva summary results (in the format described in Appendix A to this Letter Agreement) of the completed SCI-F301, SCI-F302 and MS-F202 clinical trials for Fampridine SR currently being conducted by Acorda (collectively, the “Clinical Trials”). The period commencing on the date hereof and ending on the earlier of sixty (60) days after the Trial Completion Date, or the date Teva terminates such good faith negotiations is referred to herein as the “Negotiation Period”. Upon the end of the Negotiation Period, Acorda may thereafter negotiate the terms of, and enter into, an agreement regarding rights to fampridine in any of the countries of the Territory with one or more third parties on any terms. However, Acorda may, if it so elects and Teva is willing, continue negotiations with Teva regarding reaching terms for the Fampridine Agreement. Throughout the Negotiation Period, Acorda shall not, directly or indirectly, negotiate any terms of a potential Fampridine Agreement with any party other than Teva; provided, however, that the foregoing would not prevent Acorda from (a) entering into strategic alliances with service vendors at any time before, during or after the end of the Negotiation Period, or (b) providing to possible licensees due diligence disclosures solely of technical data and intellectual property rights respecting fampridine (but in no event shall Acorda, directly or indirectly, discuss with or accept during the Negotiation Period from any licensees (or other third parties), business terms, or the economic structure of a potential agreement respecting fampridine for any country in the Territory, whether in connection with such due diligence disclosures or otherwise).

XXXXXXXXX, XX 00000	FAX: (000) 000-0000	XXX.XXXXXX.XXX

Notwithstanding the provisions of the immediately preceding paragraph of this Letter Agreement, if prior to the end of the Trial Completion Date, Acorda desires to enter into negotiations with a third party regarding terms of an agreement respecting fampridine for any country in the Territory, then Acorda shall first issue written notice to Teva requesting Teva’s best and final offer for its terms of the Fampridine Agreement (the “B&F Notice”). Teva shall then have fifteen (15) business days after its receipt of the B&F Notice to provide Acorda with its written best and final offer. If Acorda does not accept such proposed Teva best and final offer (as set forth in a written notice to Teva) or Teva fails to timely provide such a best and final offer, then Acorda shall have the right to negotiate the terms and thereafter enter into an agreement regarding rights to fampridine with a third party, provided that the terms of such third party agreement respecting fampridine are more favorable to Acorda (on a financial or such other basis as reasonably determined by Acorda) than the terms set forth in Teva’s written best and final offer (if any), and such agreement is duly executed by such third party and Acorda prior to the Trial Completion Date.

If prior to the Trial Completion Date Acorda does not enter into an agreement regarding fampridine with a third party as provided in the immediately preceding paragraph, then Teva shall have the right to provide to Acorda a written best and final offer for its terms of the Fampridine Agreement within sixty (60) days after the Trial Completion Date. If Teva issues such best and final offer and Acorda does not accept same (as set forth in a written notice to Teva), then Acorda shall have the right to thereafter proceed on its own in connection with the development, promotion and commercialization of fampridine in the Territory or enter into an agreement respecting fampridine for any country in the Territory on any terms

For clarity, it is understood that this Letter Agreement grants Teva no rights of negotiation (or any other rights) regarding fampridine in any country or territory outside the Territory, and that Acorda retains all such rights exclusively. Throughout the Negotiation Period, and following review by Teva of the summary results of the Clinical Trials in Appendix A hereof, the parties acknowledge that additional due diligence may be necessary, including on-site review and discussion at Acorda regarding protocols, protocol amendments, analytical plans, and final data. Notwithstanding the foregoing, such additional due diligence shall not be interpreted to extend the Negotiation Period beyond the term as defined above.

Please indicate your agreement with the foregoing by signing and returning a copy of this letter to the undersigned, whereupon this shall constitute a legal and binding agreement between us.

Very truly yours,

Acorda Therapeutics, Inc.		Teva Pharmaceutical Industries, Ltd.

Appendix A

As defined in the Letter Agreement to which this Appendix A is attached, the Trial Completion Date will be the last date upon which Acorda provides the following summary results of the Clinical Trials to Teva.

One summary will be provided for the each of the two Phase 3 clinical trials (SCI-F301 and SCI-F302) evaluating the safety and efficacy of Fampridine-SR in the treatment of spasticity and the Phase 2 clinical trial (MS-F202) evaluating safety and efficacy of Fampridine-SR for the treatment of lower extremity motor dysfunction

The parties agree that the following summary results may not include summary results of secondary or sub-group analyses or the extension studies, if such analyses or studies are completed after completion and delivery of the following summary results. Acorda would provide such summaries of such additional analyses or extension studies to Teva, when available, but such additional summary information shall not extend the Negotiation Period.
