(d) BIAL and its Affiliates outside the Territory will be entitled to use SEPRACOR's and SEPRACOR's Affiliates or sublicensee's documents, data and information encompassed by Section 8.1 (b)(i) and (ii) for the purposes of filing and obtaining any Approvals or marketing

authorizations outside the Territory and licensing any Third Parties to distribute, promote and commercialize products under such Approvals or marketing authorizations. SEPRACOR and its Affiliates will be entitled to use BIAL data and information encompassed by Section 8.1 (b)(i) and (ii) for the purposes of filing and obtaining any Approvals or marketing authorizations within the Territory.

(e) SEPRACOR will promptly provide BIAL with copies of any correspondence received from or sent to any regulatory authority in the Territory with respect to BIA 2-093 and/or Licensed Products. BIAL will promptly provide SEPRACOR with copies of any correspondence received from or sent to the European Medicines Evaluation Agency ("EMEA") with respect to BIA 2-093 and/or Licensed Products whenever BIAL considers it materially relevant to the development of the Licensed Products in the Territory.

8.2 Rights to Use and Reference SEPRACOR Data; Marketing Materials:

(a) In addition to the authorization granted in Section 8.1 (d) and the SEPRACOR Know-How license granted pursuant to Section 6.8, any data (including without limitation any preclinical and clinical data) Controlled by SEPRACOR during the Term relating to any Licensed Products in the Territory will be made fully available to BIAL at no cost whatsoever and BIAL and its Affiliates will have a fully paid up, royalty-free, perpetual, right to use and cross-reference such SEPRACOR data in seeking Approvals for such Licensed Products outside the Territory and/or in connection with commercialization of the Licensed Product outside the Territory.

(b) Such fully paid up, royalty-free, perpetual, right to use and cross-reference the SEPRACOR data may be extended by BIAL to its licensees or distributors outside the Territory so long as such licensees or distributors have agreed to grant a corresponding right to SEPRACOR. For clarity, this right to use and reference any SEPRACOR data by a BIAL licensee or distributor is not contingent upon the licensee or distributor having similar data, but rather its willingness to grant SEPRACOR rights to use and reference such data to the extent it exists.

(c) [**] per year or promptly upon the other Party's reasonable request, each Party will provide the other Party with specimens of its marketing materials for Licensed Products in the Field for informational purposes only. Neither Party, its Affiliates, licensees, distributors or other Third Parties will use the other Party's marketing materials to market, sell or offer for sale Licensed Products without such Party's prior written consent.

BIAL will be responsible for all Pharmacovigilance related activities until such agreement is signed. BIAL will have all relevant Affiliates and other licensees become a party to such PVEA or to enter into similar agreement(s) with BIAL in order to ensure global regulatory compliance. The PVEA will describe the collection, investigation, analysis, reporting, and exchange of information concerning adverse events, product safety and product complaints relating to the Licensed Products, sufficient to permit each Party, its Affiliates, sublicensees or licensees to comply with its legal or regulatory obligations, including to the extent applicable, those obligations contained in ICH guidelines.

(b) If a Licensed Product becomes subject to a pattern of Serious Adverse Reactions (as defined in the ICH Guidelines) or either Party receives notice from a regulatory authority relating to a significant concern for patient safety, the Parties will in good faith analyze and agree on risk minimization measures and other reasonable actions to be carried out, by either Party or both Parties, in relation to such Licensed Product, including without limitation, the modification of the relevant Approval

8.4 Quality Agreement. Simultaneous with the execution of the Supply Agreement, the Parties will enter into a Quality Agreement with terms appropriate for the manufacture of finished products for commercial distribution.

ARTICLE 9

INTELLECTUAL PROPERTY

9.1 Ownership of Development Intellectual Property: All Development Intellectual Property conceived solely by the employees of a Party will be owned by that Party. Development Intellectual Property conceived by employees of both Parties will be jointly owned by the Parties, each having an equal and undivided interest in such Development Intellectual Property.

(a) Any Development Intellectual Property that BIAL Controls or is jointly owned by the Parties will be encompassed by the licenses set forth in Sections 2.1 and 2.2 without additional consideration other than the payments set forth in Article 3, provided however that the Licensed Products will be subject to the transfer price and/royalty provisions of Article 4.

(b) SEPRACOR grants BIAL an exclusive (even as to SEPRACOR), royalty-free, fully paid-up, perpetual license, with the right to grant sublicenses, under any Development Intellectual Property that SEPRACOR Controls or is jointly owned by the Parties, to make, have made, use, import, develop, offer for sale and sell products (including without limitation Licensed Products) or processes outside of the Territory for as long as BIAL Controls (by license or otherwise) outside the Territory any patent, patent application, or other intellectual property right which would be infringed by the making, importation, use, development, sale or offer for sale of any product or process encompassed by such Development Intellectual Property ("Blocking BIAL IP"). After expiration of such Blocking BIAL IP, the license under this Section 9.1(b) will convert to a Semi-Exclusive, royalty-free, fully paid-up, perpetual license, with the right to grant sub-licenses under any Development Intellectual Property that SEPRACOR Controls to make, have made, use, import, develop, offer for sale and sell any products (including without limitation Licensed Products) or processes outside of the Territory. For the purposes of this Section 9.1(b), the term "Semi-Exclusive License" means that, in addition to BIAL, SEPRACOR will have the right, directly or through one licensee, to make, have made, use, import, offer for sale and sell such products (including without limitation Licensed Products) or processes outside of the Territory under the SEPRACOR Development Intellectual Property.

(c) Subject to SEPRACOR's rights set forth in Section 2.2(a), SEPRACOR also grants BIAL a royalty-free, fully paid-up, perpetual, non-exclusive license, with the right to grant sublicenses, under any Development Intellectual Property that SEPRACOR Controls to the extent necessary to allow BIAL, its Affiliates, and Third Party licensees to develop products (including without limitation Licensed Products) or processes within the Territory for use outside of the Territory.

(d) During the Term of this Agreement, SEPRACOR will use Commercially Reasonable Efforts to retain all right, title and interest in any Development Intellectual Property that is conceived solely by the SEPRACOR sublicensee or a contractor or jointly by SEPRACOR and the SEPRACOR sublicensee or a contractor. If SEPRACOR, despite such efforts, is unable to retain all right, title and interest in any such Development Intellectual Property it will use Commercially Reasonable Efforts to negotiate an exclusive, world-wide license under such Development Intellectual Property to make, have made, use, import, develop, offer for sale and sell products (including without limitation Licensed Products) or processes, with the right to xxxxx XXXX (a) an exclusive (even as to licensor and SEPRACOR) sublicense, with the right to grant further sublicenses, under such Development Intellectual Property to make, have made, use, import, develop, offer for sale and sell products (including without limitation Licensed Products) or processes outside the Territory and (b) a non-exclusive sublicense, with the right to grant further

sublicenses, under such Development Intellectual Property to develop products (including without limitation Licensed Products) or processes within the Territory for use outside of the Territory, provided that BIAL agrees, in writing, to: (i) comply with any terms that may apply to such disclosure/sublicensing; (ii) pay [**]; and (iii) pay [**]. SEPRACOR will use Commercially Reasonable Efforts to obtain reasonable terms when negotiating BIAL's sublicense.

(e) Any license granted under Sections 9.1 (b), (c) and (d) will expire upon the last to expire of the licensed patents encompassed by such license.

(f) The Parties agree that, to the extent it is required by the laws of any country, the Parties will execute necessary documentation to reflect or record any licenses under jointly owned Developmental Intellectual Property licenses or sublicenses granted in accordance with this Agreement under any Developmental Intellectual Property.

9.2 Prosecution of Development Intellectual Property:

(a) Each Party may, at its own expense, file, prosecute, maintain, defend and enforce the patents and patent applications relating to Development Intellectual Property which are owned solely by that Party.

(b) Notwithstanding Section 9.2(a), SEPRACOR will have the first opportunity to file U.S. and foreign patent applications on any Development Intellectual Property Controlled solely by SEPRACOR or jointly owned by SEPRACOR and its sublicensee or a contractor. SEPRACOR will cause a copy of any such patent application and all communications between its agents and any patent office regarding each such patent application and/or patent to be provided to BIAL or its agent for comment, within a reasonable deadline prior to submitting such communications to the patent office. Provided that BIAL responds within the specified deadline, SEPRACOR will consider or cause its agents to consider, in good faith, any comments BIAL may have regarding that application or communication, provided that all final prosecution decisions will rest solely with SEPRACOR. BIAL will be responsible for any expenses that it may incur in providing such comments. SEPRACOR (or its sublicensee or a contractor) will pay all official taxes, annuities, renewal and maintenance fees required to keep in force all issued patents for Development Intellectual Property solely Controlled by the SEPRACOR or jointly owned by SEPRACOR and its sublicense or any of its contractors.

(c) BIAL has the right to file a patent application for Development Intellectual Property Controlled by SEPRACOR in any country in which SEPRACOR decides not to file. SEPRACOR will notify BIAL of the decision not to file a patent application in a particular country within [**] of making that decision, but not later than [**] prior to the time when any statutory bar might foreclose filing of a patent application in that country. Upon receipt of such notification, BIAL has the option to assume full responsibility, at its own discretion and expense, to file a patent application in any such country, in which event SEPRACOR will reasonably cooperate and assist BIAL, at BIAL's expense, in executing a written assignment of the Development Intellectual Property to BIAL in that country and provide any other conveyance instruments, documents or assistance as may be necessary or desirable to establish ownership or to support of the prosecution of the application. In the event that such patent application becomes the subject of an opposition or related proceeding, or if any patent(s) to issue becomes involved in any adversary proceeding (e.g. litigation, nullity or revocation proceedings), BIAL will provide SEPRACOR notice of such proceeding and BIAL will provide SEPRACOR reasonable opportunity to comment and advise to BIAL.

(d) SEPRACOR will advise BIAL if it no longer desires to continue prosecution or pay maintenance fees, on any patent application or patent either in the United States or any foreign country for Development Intellectual Property Controlled by SEPRACOR. Such notification will be in writing and will be provided not less than [**] before the expiration of a response period or the payment due date for a maintenance fee. Upon receipt of such notification, BIAL has the option, exercisable upon written notification to SEPRAOR, to assume the prosecution and/or maintenance of the patent application or patent, in which event SEPRACOR will reasonably cooperate with and assist BIAL, at BIAL's expense, in executing a written assignment of the patent application or patent to BIAL and provide any other conveyance instruments, documents, or assistance as may be necessary or desirable to establish ownership of the patent or patent application or to support of the prosecution of the application.

(e) BIAL will use Commercially Reasonable Efforts to file, prosecute and maintain patents and patent applications filed inside and outside the Territory on all Development Intellectual Property jointly-owned by the Parties. All costs including legal fees, official taxes, annuities, renewal, and maintenance fees required to prosecute all such applications and keep in force all

issued patents that are jointly owned by the Parties, will be [**] with respect to patents and patent applications in the Territory and [**] with respect to patents and patent applications outside the Territory. If BIAL desires to discontinue its participation in the prosecution of any jointly-owned patent application or maintenance fee of an issued patent, it will notify SEPRACOR in writing not less than [**] before the expiration of a response period or the payment due date for a maintenance fee. Upon receipt of such notification, SEPRACOR has the option to assume full responsibility, at its discretion and expense, for the prosecution and maintenance of the affected patent application(s) or patent(s) in or outside the Territory, in which event BIAL will reasonably cooperate with and assist SEPRACOR, at SEPRACOR's expense, in executing a written assignment of the patent application or patent to other Party and provide any other conveyance instruments, documents, or assistance as may be necessary or desirable to establish ownership of the patent or patent application or to support the prosecution of the application. Except as otherwise provided in Section 2.1(a), neither Party [**]

recalled or withdrawn, (ii) a court of competent jurisdiction orders a recall or withdrawal of a Licensed Product in the Territory, or (iii) SEPRACOR determines that an event, incident or circumstance has occurred that warrants a Licensed Product should be recalled or withdrawn voluntarily in the Territory, the Parties will recall or withdraw the Licensed Product as set forth in this Section 15.6.

(i) is caused by breach of BIAL's representations or warranties as set forth in this Agreement or the Supply Agreement, including failure to supply Licensed Product conforming to the specifications set forth in the Supply Agreement or Quality Agreement, or the gross negligence or willful misconduct of BIAL or BIAL's failure to comply with applicable laws and regulations including cGMP (to be defined in the Quality Agreement) (collectively, the "Fault of BIAL"), BIAL will be responsible for all Recall Costs; and

(ii) is caused by breach of SEPRACOR's representations or warranties as set forth in this Agreement or the Supply Agreement, including failure of SEPRACOR, or its Affiliates, its sublicensee or contractors, to handle, store, transport, market, promote, distribute, sell or use the Licensed Product in accordance with applicable laws and regulations or the terms of the applicable Approval, the Supply Agreement, the Quality Agreement or the gross negligence or willful misconduct of SEPRACOR, its Affiliates, sublicensee or contractors (collectively, "Fault of SEPRACOR"), SEPRACOR will be responsible for all Recall Costs.

15.7 Product Liability Claims.

(a) Notification to the Other. Each Party will notify the other Party as promptly as practicable if any Third Party claim is commenced or threatened against such Party alleging product liability, product defect, design, packaging or labeling defect, failure to warn or any similar action relating to the use or safety of any Licensed Product sold by or under authority of SEPRACOR, its Affiliates or sublicensee in the Territory (a "Product Liability Claim"). BIAL will notify SEPRACOR as promptly as practicable of any Product Liability Claim with respect to any Licensed Product sold by or under authority of BIAL outside of the Territory.

(b) Cooperation, Counsel and Control. Each Party will cooperate with the other Party in connection with any such Product Liability Claim that is commenced or threatened against the other Party.

If a Product Liability Claim is brought against one Party but not the other Party, the named Party will control the defense and/or settlement thereof at its own expense with counsel of its choice, subject to this Section 15.7. In such case, the other Party may participate in the defense and/or settlement thereof at its own expense with counsel of its choice. In any event, the Party that is subject to a Product Liability Claim (if not asserted against both Parties) agrees to keep the other Party hereto informed of all material developments in connection with any such Product Liability Claim.

(c) Settlement, Admissions and Asserting Positions. Neither Party will settle any Product Liability Claim, or make any admissions or assert any position in such Product Liability Claim, in a manner that would adversely affect the other Party, the Licensed Product or the development, manufacture, use or sale thereof without the prior written consent of the other Party, which will not be unreasonably withheld or delayed.

(d) Bearing the Liabilities. To the extent a Product Liability Claim is caused by: (i) the Fault of BIAL, BIAL will bear all Liabilities from such Product Liability Claim to the extent of its fault, (ii) the Fault of SEPRACOR, SEPRACOR will bear all Liabilities from such a Product Liability Claim to the extent of its fault, or (iii) circumstances other than those described in Sub-section (i) or (ii), above, [**].

The arbitration proceeding will be held and the award issued in London, England although the Parties may agree in writing to conduct the arbitration proceedings in a different location. The

Parties agree that only documents directly relevant to the issues in dispute must be produced in any such arbitration. The arbitration will be conducted as expeditiously as practicable, and the Parties and the arbitrators will use their best efforts to hold the hearing on the merits no later than [**] after the appointment of the arbitration tribunal and the arbitrators will use their best efforts to issue a final award within [**] after the close of the hearing.

(e) In addition to damages, the arbitration tribunal may award any remedy provided for under applicable law and the terms of this Agreement, including, without limitation, specific performance or other forms of injunctive relief. The arbitration tribunal is not empowered to award damages in excess of compensatory damages, and each Party hereby irrevocably waives any right to recover punitive, exemplary, multiplied (including without limitation treble), consequential or similar damages with respect to any dispute. The arbitration award must be in writing and will state, in English and in reasonable detail, the findings of fact and conclusions of law on which it is based. The arbitration award will be final and binding on the parties and will not be appealable except as otherwise provided for by applicable treaty or law and may be entered and enforced in any court having competent jurisdiction.

(f) Each Party will pay its own expenses of arbitration and the expenses of the arbitration tribunal and the ICC will be equally shared, except that if, in the opinion of the arbitration tribunal, any claim by a Party hereto or any defense or objection thereto by the other Party was unreasonable, the arbitration tribunal may in their discretion assess as part of the award all or any part of the arbitration expenses of the other Party (including reasonable attorneys' fees) and the fees and expenses of the arbitration tribunal and the ICC against the Party raising such unreasonable claim, defense or objection.

16.2 Either Party may, without inconsistency with this agreement to arbitrate, apply to a court to seek pre-arbitral provisional injunctive relief to maintain the status quo or prevent irreparable harm, pre-arbitral attachment, or any other relief or order in aid of arbitration proceedings and the enforcement of any award. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitration tribunal will have full authority to grant provisional remedies and to direct the Parties to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any Party to respect the arbitrator(s)' orders to that effect.

16.3 Force Majeure: If any circumstance beyond the reasonable control of either Party occurs which delays or renders impossible the performance of that Party's obligations under this Agreement on the dates herein provided (a "Force Majeure"), such obligation will be postponed for such time as the event of Force Majeure exists, provided such Party notifies the other Party in writing as soon as practicable, but in no event more than ten (10) Business Days after the inception of such event of Force Majeure. The Party so affected will give to the other Party a good faith estimate of the continuing effect of the Force Majeure condition and the anticipated duration of the affected Party's non-performance. Notwithstanding the foregoing, if the period of any previous actual non-performance of a Party because of Force Majeure conditions plus the anticipated future period of non-performance because of such conditions will exceed an aggregate of one hundred eighty (180) days, then the Party unaffected by such event may terminate this Agreement by not less than sixty (60) days written notice of termination to the other Party; provided that, if the Force Majeure event ceases within such sixty (60) day period, this Agreement will remain in full force and effect. Events of Force Majeure will include, without limitation, war, revolution, invasion, insurrection, riots, mob violence, sabotage or other civil disorders, acts of God, limitations imposed by exchange control regulations or foreign investment regulations or similar regulations, laws, regulations or rules of any government or governmental agency, any inordinate delays in the regulatory review or governmental approval process that are within the sole control of such government or governmental agency. A Party will be considered

affected by an event of Force Majeure to the extent that any of its suppliers or contractors is affected by such an event.

16.4 Assignment: Except as set forth in Section 14.2(d), neither Party may assign, transfer or otherwise dispose of this Agreement or any rights or obligation with respect thereto, to any other party without the prior written consent of the other Party, provided however that BIAL may assign or transfer this Agreement, or any part or right or obligation thereof, to any Affiliate, or in connection with the transfer or sale of all or substantially all of its assets related to the Licensed Products or the business to which this Agreement relates, without SEPRACOR's consent. Any attempted or purported assignment or transfer of rights or obligations other than provided herein will be void.

16.5 Performance by Affiliates: Either Party may exercise any of its respective rights and perform any of its respective obligations hereunder through any of its Affiliates.

16.6 No Third Party Beneficiaries: This Agreement does not confer any rights or remedies upon any person or entity other than SEPRACOR and BIAL and their respective successors and permitted assigns and sublicensees.

16.7 Waiver: The waiver by a Party, whether express or implied, of any provisions of this Agreement, or of any breach or default of a Party, will not be construed to be a continuing waiver of such provision, or of any succeeding breach or default, or a waiver of any other provisions of this Agreement.

16.8 Governing Law: All matters affecting the interpretation, validity, and performance of this Agreement will be governed by the laws of New York, U.S.A. without regard to its choice or conflict of law principles.

16.9 Unenforceable Provisions: Any provision hereof that is prohibited or unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction. The Parties will replace such ineffective provision for such jurisdiction with a valid and enforceable provision which most closely approaches the idea, intent, and purpose of this Agreement, and in particular, the provision to be replaced.

16.10 Relationship Between the Parties: BIAL and SEPRACOR are independent contractors and will not be deemed to be partners, joint venturers or each other's agents, and neither will have the right to act on behalf of the other except as may be expressly agreed to in writing.

16.11 Entire Agreement: It is the mutual desire and intent of the Parties to provide certainty as to their future rights and remedies against each other by defining the extent of their mutual undertakings as provided herein. The Parties have in this Agreement incorporated all representations, warranties, covenants, commitments and understandings on which they have relied in entering into this Agreement and, except as provided for herein, neither Party has made any covenant or other commitment to the other concerning its future action. Accordingly, this Agreement, the Supply Agreement, the PVEA and Quality Agreement and the exhibits attached hereto and thereto (i) constitute the entire agreement and understanding between the Parties with respect to the matters contained herein, and there are no promises, representations, conditions, provisions or terms related thereto other than those set forth in this Agreement, and (ii) supersedes all previous understandings, agreements and representations between the Parties, written or oral relating to the subject matter hereof.

PRESS RELEASE

Sepracor Inc. and Bial Announce Exclusive Licensing Agreement for Development and Commercialization of Anti-Epileptic Compound in United States and Canada

BIA 0-000, Xxxxxxxxxxxxxxx Xxxxxxx, has Completed Large-Scale Phase III Clinical Studies

Submission of U.S. New Drug Application (NDA) Anticipated Late 2008 or Early 2009

U.S. Anti-Epileptic Market Estimated at Approximately $4 Billion in 2006

MARLBOROUGH, Mass. & X. XXXXXX DO XXXXXXXX, Portugal—(BUSINESS WIRE)—Jan. 2, 2008—Sepracor Inc. (Nasdaq: SEPR) and Bial today announced an exclusive licensing agreement for the development and commercialization of Bial's anti-epileptic compound BIA 2-093 in the United States and Canada. Under the terms of the agreement, Sepracor will be responsible for filing the U.S. NDA and seeking marketing approval from the U.S. Food and Drug Administration (FDA), and contingent on obtaining regulatory approval, commercialization of the product in the U.S. Sepracor anticipates that the NDA will be submitted to the FDA in late 2008 or early 2009 with a potential product launch in late 2009 or early 2010, subject to FDA approval. In exchange, Bial is entitled to receive an upfront payment of $75 million and subsequent payments upon accomplishment of various development and regulatory milestones, which could include up to an additional $100 million if all milestones are met. Bial will also receive compensation for providing finished product and milestone payments upon FDA approval of additional indications, if any.

"We are very pleased with the addition of this late-stage asset to our growing product pipeline," said Xxxxxx Xxxxx, President and Chief Executive Officer of Sepracor. "Strategically, BIA 2-093 further strengthens our existing central nervous system portfolio, which includes LUNESTA(R) brand eszopiclone for the treatment of insomnia, as well as earlier-stage candidates for various central nervous system disorders. This milestone in-licensing event is reflective of our overall global corporate strategy to fully leverage our product franchises and commercial infrastructure while driving enhanced research and development productivity and successfully pursuing aligned and value-enhancing corporate development and licensing initiatives."

"In Sepracor we have found a partner who truly shares our vision and commitment to this compound and a company with a proven commercial track record in the U.S. market. This is a landmark event for BIAL and represents the first result of our R & D work within the CNS area. I am very proud of the people within BIAL who have helped to make this happen through their hard work and dedication" said Xxxx Xxxxxxx, President and Chief Executive Officer of Bial.

BIA 2-093 (eslicarbazepine acetate) is a new chemical entity which has been designed to offer patients suffering with partial epilepsy additional control of their seizures and improved quality of life. Bial is currently completing clinical evaluation of BIA 2-093 for the adjunctive use in partial seizures in adults with epilepsy.

Eslicarbazepine acetate has been shown in clinical studies to be safe and effective in the control of seizures as adjunctive therapy in adults. Bial has tested the compound in three Phase III trials in 22 countries with over one thousand patients randomized to an 18-week acute double-blind therapy and subsequently followed in a one year, open label extension study. The potential for once-daily administration could be an important clinical advantage for patients with epilepsy in the U.S. and Canada. In addition, there may be benefits to patients such as reduced drug-drug interactions, which may distinguish this drug from commonly used compounds such as carbamazepine.

According to the National Institute of Neurological Disorders and Stroke, epilepsy is a brain disorder in which clusters of nerve cells, or neurons, in the brain sometimes signal abnormally. In epilepsy, the normal pattern of neuronal activity becomes disturbed, causing strange sensations, emotions, and behavior or sometimes convulsions, muscle spasms, and loss of consciousness. Epilepsy is a disorder with many possible causes. Anything that disturbs the normal pattern of neuron activity—from illness to brain damage to abnormal brain development—can lead to seizures. Epilepsy may develop because of an abnormality in brain wiring, an imbalance of nerve signaling chemicals called neurotransmitters, or some combination of these factors.
