NOW, THEREFORE, in consideration of and reliance upon the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

Scopia shall (i) cause the Scopia Management Directors and (ii) use its reasonable best efforts to cause the Scopia Non-Management Directors to, as promptly as practicable upon request of the Company, provide the Company (i) executed consents from any Scopia Directors to serve as a director if appointed pursuant to the terms hereof, (ii) any information required to be or reasonably and customarily disclosed for all applicable directors, candidates for directors, and their affiliates and representatives in a proxy statement or other filings under applicable law or stock exchange rules or listing standards, (iii) completed copies of the Company’s standard D&O Questionnaires in the form provided to Scopia by the Company and information in connection with assessing eligibility, independence and other criteria applicable to all applicable directors or satisfying compliance and legal obligations applicable to all independent directors, (iv) written acknowledgments by each Scopia Director that such Scopia Director agrees to comply with all lawful agreements, policies, codes, rules, standards

For purposes of this Agreement, the term “Confidential Information” shall mean any and all information concerning or relating to the Company or any of its subsidiaries or Affiliates that is furnished (regardless of the manner in which it is furnished, including in written or electronic format or orally, gathered by visual inspection or otherwise) to a Scopia Director or counsel of a Scopia Director or Scopia by or on behalf of the Company or its agents, representatives, attorneys, advisors, directors, officers or employees (“Company Representatives”), together with all notes, analyses, reports, models, compilations, studies, interpretations, documents, records or extracts thereof containing, referring, relating to, based upon or derived from such information, in whole or in part. The term “Confidential Information” shall not include such information that (a) was provided to or made available to Scopia, a Scopia Director, any Scopia Representative (acting on behalf of Scopia) or a Scopia Affiliate on a non-confidential basis prior to it being furnished to a Scopia Director or counsel of a Scopia Director or Scopia by or on behalf of the Company or any Company Representative from a source not known, after reasonable inquiry, to bound by an agreement or obligation of confidentiality with respect to such information, (b) is or becomes generally available to the public other than as a result of a disclosure by the Scopia Director, Scopia, any of their respective Affiliates or any Scopia Representative in violation of this Agreement, or (c) has been or is independently developed by the Scopia Director, Scopia, any of their respective Affiliates or any Scopia Representative without the use of any Confidential Information. Notwithstanding the foregoing, the Scopia Directors may provide Confidential Information to any Scopia officer, member, partner, employee or counsel (each, a “Scopia Representative”) for the purpose of advising Scopia on its investment in the Company or advising Scopia as to its rights and obligations under this Agreement, and may discuss such Confidential Information with such persons for such purposes, provided that any such Scopia Representative provided with any such information shall be directed to comply with the terms of this Section 7; and, in any event, Scopia shall be responsible for any non-compliance with such confidentiality requirements by any Scopia Representative who is provided with such information. Scopia shall take all reasonable measures to restrain each Scopia Representative from prohibited or unauthorized disclosure of the Confidential Information. In furtherance, and not in limitation, of the foregoing, Scopia shall, and shall instruct each Scopia Representative to, use all reasonable and prudent efforts to protect and safeguard the Confidential Information from disclosure to at least the same extent such person does so with respect to Scopia’s confidential information and be directed to comply with the terms of this Section 7. It is understood and agreed that the Scopia Director shall not disclose to Scopia or any Scopia Representative any Legal Advice (as defined below) that may be included in the Confidential Information with respect to which such disclosure may constitute waiver of the Company’s attorney-client privilege or attorney work-product privilege; provided that any such privileged communications or Legal Advice are plainly identified as such when disclosed to the Scopia Directors. “Legal Advice” as used herein shall be solely and exclusively limited to the advice provided by legal counsel and shall not include

factual information or the formulation or analysis of business strategy that is not protected by the attorney-client or attorney work-product privilege.

(b)In the event that Scopia, a Scopia Director or any Scopia Representative becomes legally compelled (including any request or demand of or by a regulatory authority having jurisdiction over Scopia, such Scopia Director or such Scopia Representative) to disclose any Confidential Information, Scopia, the Scopia Directors and the Scopia Representatives, as applicable, will promptly as practicable notify (except where such notice would be legally prohibited) the Company of the existence, terms and circumstances surrounding such a request, so that it may seek an appropriate protective order or other appropriate remedy and/or waive compliance with the provisions of this Section 7 and, Scopia, the Scopia Directors and the Scopia Representatives (as the case may be) will provide such cooperation as the Company shall reasonably request at the Company’s sole cost and expense. If, in the absence of a protective order or the receipt of a waiver hereunder, Scopia, such Scopia Director or such Scopia Representative is nonetheless, based on the advice of Scopia’s, such Scopia Director or Scopia’s Representatives’ legal counsel, required to disclose any such information, Scopia, such Scopia Director or such Scopia Representative, as the case may be, (i) may disclose, without liability hereunder, only that portion of the Confidential Information that Scopia, such Scopia Director or such Scopia Representative is legally required to disclose and (ii) shall, unless otherwise required by law or regulations, exercise its reasonable best efforts to obtain an order or other reliable assurance that confidential treatment will be accorded to such information to be disclosed. In no event will Scopia, any Scopia Director or any Scopia Representative oppose action by the Company to obtain a protective order or other remedy to prevent the disclosure of Confidential Information or to obtain reliable assurance that confidential treatment will be accorded the Confidential Information. For the avoidance of doubt, it is understood that there shall be no “legal requirement” requiring Scopia, any Scopia Director or any Scopia Representative to disclose any Confidential Information solely by virtue of the fact that, absent such disclosure, any of them or any of their respective Affiliates, would be prohibited from purchasing, selling or engaging in derivative or other voluntary transactions with respect to, the Securities of the Company or the securities of any other company or otherwise proposing or making an offer to do any of the foregoing, or any of them would be unable to file any proxy materials in compliance with Section 14(a) of the Exchange Act or the rules and regulations promulgated thereunder.

(c)Scopia acknowledges that (a) none of the Company or any of the Company Representatives makes any representation or warranty, express or implied, as to the accuracy or completeness of any Confidential Information, and (b) none of the Company or any of its representatives shall have any liability to Scopia, any Scopia Director, any Scopia client, any Scopia Representative or any of their respective Affiliates relating to or resulting from the use of the Confidential Information or any errors therein or omissions therefrom; provided, however, that the foregoing will not limit the Company’s liability to the extent such information was disclosed publicly by the Company.

(d)All Confidential Information shall remain the property of the Company. No other person shall by virtue of any disclosure of and/or use of any Confidential Information acquire any rights with respect thereto, all of which rights shall remain exclusively with the Company. At any time after the date on which this Agreement has been validly terminated pursuant to Section 13 hereof or following a Resignation Trigger, Scopia shall, and shall cause

the Scopia Directors to, promptly, upon written request by the Company, return to the Company or destroy all hard copies of the Confidential Information and use commercially reasonable efforts to permanently erase or delete all electronic copies of the Confidential Information in their or any of the Scopia Representatives’ possession or control (and, upon the request of the Company, shall certify to the Company in writing that such Confidential Information has been erased or deleted, as the case may be); provided, however, that Scopia and the Scopia Representatives shall be entitled to retain copies of the Confidential Information to the extent required by applicable law or regulation or by its bona fide internal compliance policies; provided that such Confidential Information is not accessible in the ordinary course of business and is not accessed except as required for such back-up purposes (it being understood that the confidentiality and use provisions of this agreement shall survive for the period set forth in Section 13). Notwithstanding the return or erasure or deletion of Confidential Information, Scopia and the Scopia Representatives will continue to be bound by the obligations contained herein for the period set forth in Section 13.

(e)Scopia hereby acknowledges that it is aware that the United States securities laws may prohibit any person who has received from an issuer any material, non-public information from purchasing or selling securities of such issuer or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities.

8.Miscellaneous. The Parties agree that irreparable damage may occur in the event any of the provisions of this Agreement were not performed in accordance with the terms hereof and that such damage would not be adequately compensable in monetary damages. Accordingly, the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement, to enforce specifically the terms and provisions of this Agreement exclusively in the Court of Chancery of the State of Delaware or, if such court shall not have jurisdiction, any state or federal court sitting in the State of Delaware, and to require the resignation of the Scopia Directors from the Board following a Resignation Trigger or Scopia and the Scopia Affiliates, collectively, ceasing to beneficially own an aggregate Net Long Position of at least 10% of the Company Stock then outstanding (other than as a result of any action by the Company that has a dilutive effect, including stock issuances), in addition to any other remedies at law or in equity, and each party agrees it will not take any action, directly or indirectly, in opposition to another party seeking or obtaining such relief. Each of the Parties hereto agrees to waive any bonding requirement under any applicable law, in the case any other Party seeks to enforce the terms hereof by way of equitable relief. Furthermore, each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the Court of Chancery of the State of Delaware and the federal and other state courts sitting in the State of Delaware in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated by this Agreement in any court other than such federal or state courts of the State of Delaware, and each of the parties irrevocably waives the right to trial by jury, and (d) each of the parties irrevocably consents to service of process by a reputable overnight mail delivery service, signature requested, to the address set forth in Section 11 hereof or as otherwise provided by applicable law. THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS, INCLUDING VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS

OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS EXECUTED AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE WITHOUT GIVING EFFECT TO ANY CONFLICT OR CHOICE OF LAW PRINCIPLES THAT MAY RESULT IN THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

9.Expenses. All attorneys’ fees, costs and expenses incurred in connection with this Agreement and all matters related hereto will be paid by the party incurring such fees, costs or expenses; provided that the Company will reimburse Scopia for its reasonable, documented out-of-pocket legal costs incurred in connection with the Agreement, including in connection with the nomination and appointment of the Scopia Directors pursuant to Section 1, up to a maximum aggregate amount of $100,000.

10.Entire Agreement; Amendment. This Agreement and all exhibits attached hereto contain the entire agreement and understanding of the parties with respect to the subject matter hereof and supersede any and all prior and contemporaneous agreements, memoranda, arrangements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof. This Agreement may be amended only by an agreement in writing executed by the parties hereto, and no waiver of compliance with any provision or condition of this Agreement and no consent provided for in this Agreement shall be effective unless evidenced by a written instrument executed by the party against whom such waiver or consent is to be effective. No failure or delay by a party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege hereunder.

11.Notices. All notices, consents, requests, instructions, approvals and other communications provided for herein and all legal process in regard hereto shall be in writing and shall be deemed validly given, made or served, when actually received during normal business hours at the address specified in this subsection:

ARDSLEY, NY, DATE – Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced that it has entered into a cooperation agreement with Scopia Capital Management LP.

Forward-Looking Statement

This press release includes forward-looking statements. All statements, other than statements of historical facts, regarding management's expectations, beliefs, goals, plans or prospects should be considered forward-looking. These statements are subject to risks and uncertainties that could cause actual results to differ materially, including: the ability to realize the benefits anticipated from acquisitions, among other reasons because acquired development programs are generally subject to all the risks inherent in the drug development process and our knowledge of the risks specifically relevant to acquired programs generally improves over time; we may need to raise additional funds to finance our operations and may not be able to do so on acceptable terms; our ability to successfully market and sell Ampyra (dalfampridine) Extended Release Tablets, 10 mg in the U.S., which will likely be materially adversely affected by the March 2017 court decision in our litigation against filers of Abbreviated New Drug Applications to market generic versions of Ampyra in the U.S.; the risk of unfavorable results from future studies of Inbrija (levodopa inhalation powder) or from our other research and development programs, or any other acquired or in-licensed programs; we may not be able to complete development of, obtain regulatory approval for, or successfully market Inbrija or any other products under development; third party payers (including governmental agencies) may not reimburse for the use of Ampyra, Inbrija or our other products at acceptable

C-1

rates or at all and may impose restrictive prior authorization requirements that limit or block prescriptions; the occurrence of adverse safety events with our products; the outcome (by judgment or settlement) and costs of legal, administrative or regulatory proceedings, investigations or inspections, including, without limitation, collective, representative or class action litigation; competition; failure to protect our intellectual property, to defend against the intellectual property claims of others or to obtain third party intellectual property licenses needed for the commercialization of our products; and failure to comply with regulatory requirements could result in adverse action by regulatory agencies.

These and other risks are described in greater detail in our filings with the Securities and Exchange Commission. We may not actually achieve the goals or plans described in our forward-looking statements, and investors should not place undue reliance on these statements. Forward-looking statements made in this press release are made only as of the date hereof, and we disclaim any intent or obligation to update any forward-looking statements as a result of developments occurring after the date of this press release.
