Any of the obligations in this Section 3.5 and the development plan set forth in Exhibit D attached hereto may be modified by Chelsea subject to DSP’s written approval, which approval shall not be unreasonably withheld or delayed. DSP’s sole and exclusive remedy for any failure by Chelsea to perform its obligations under this Section 3.5 shall be to terminate this Agreement by providing Chelsea with sixty (60) days prior written notice, unless Chelsea commences or resumes to perform such obligations during such sixty (60) day period.

3.6 ADR Reporting. Each Party agrees to provide each other with adverse drug events occurring or having occurred in connection with the use of the L-DOPS and/or the Licensed Product which come into its knowledge. The Parties agree to handle data and information on adverse drug events occurring or having occurred in connection with the use of the L-DOPS and/or the Licensed Product according to the respective ICH-Guidelines, FDA requirements, requirements of the relevant European registration authorities, requirements of the Regulatory Authority and/or requirements of any other relevant regulatory authority. Any information furnished by either DSP or Chelsea under this Section 3.6 shall be treated as Confidential Information pursuant to Section 9 of this Agreement, provided that either Party may provide such information to the Regulatory Authority in compliance with any applicable law and/or regulation.

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

After completion of the last clinical trial for the application for the Marketing Authorization Approval for the first country in which such application is to be made, but no later than the expected date when Chelsea obtains the first Marketing Authorization Approval in the Territory, the Parties shall negotiate in good faith and execute a Post Marketing Pharmacovigilance Agreement which includes, without limitation, handling of post marketing studies and spontaneous or literature reports, surveillance in relation to the Licensed Product, in the Territory by Chelsea, its Affiliates and its Sublicensees, and outside the Territory by DSP, its Affiliates and its licensees, specifying the procedure for the exchange of information on the adverse drug events which may occur after the first commercial sale of the Licensed Product.

DSP shall be solely responsible for reporting adverse drug events to the regulatory authorities outside the Territory. Chelsea, as a party owning the Marketing Authorization Approval or any application thereof, including an IND and an NDA, shall be solely responsible for reporting adverse drug events to the Regulatory Authority in the Territory. The Parties will maintain a safety database for L-DOPS and the Licensed Product to enable the Parties to manage safety data collected and fulfill their own regulatory requirements.

3.6.1 Further Provisions. Both as an integral part of the procedures referred to in Section 3.6 and as a separate obligation under this Agreement, further provisions concerning the reporting and notification of adverse drug reactions shall be separately negotiated in good faith and agreed upon by the Parties promptly after Effective Date to comply with regulatory requirements.

3.7 Postponement. Upon receiving the Marketing Authorization Approval in any country of the Territory, Chelsea shall notify DSP in writing of that event, together with the expected date of First Commercial Sale, which shall not be unreasonably late after receiving the Marketing Authorization Approval. Chelsea may change such expected date of First Commercial Sale, at no cost to Chelsea, by notifying DSP in writing, together with rationale for such change, prior to the beginning of the calendar month during which the expected date of such First Commercial Sale is scheduled to occur. Chelsea may not postpone the expected date of First Commercial Sale (“Postponement”) more than once in any country of the Territory. In the event of a Postponement, other than due to a delay in supply of the Compound by DSP, Chelsea shall be responsible for and pay to DSP the costs of the Compound ordered under any firm order (whether such orders have been delivered by DSP or not) subject to the conditions set forth in the Supply Agreement, and Chelsea shall have no other responsibility to DSP as a result of such Postponement.

Each milestone payment above shall only be made once under this Agreement upon the initial accomplishment of the relevant milestone.

4.3 Running Royalty. Chelsea shall pay DSP, within ninety (90) days following the end of each calendar year, [*] Percent ([*]%) of Net Sales of each Licensed Product by Chelsea, its Affiliates and its Sublicensees for the previous calendar year. All obligations of Chelsea to pay DSP royalties for Exploitation of Licensed Products shall expire (i) with respect to the North America which constitutes

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

USA, Canada and Mexico, eight (8) years after the First Commercial Sale in USA, and (ii) with respect to the remainder of the Territory, eleven (11) years after the First Commercial Sale in any country of UK, France, Italy, Germany and Spain, and upon expiration of the relevant royalty term, all of the licenses and rights granted to Chelsea hereunder shall become irrevocable, perpetual, fully-paid, and royalty-free.

4.4 Bundling. In the event that a Licensed Product is included as a “bundle” of products or services, Chelsea, as applicable, may discount the list price of the Licensed Product contained in the bundle in calculating the Net Sales of such Licensed Product for purposes of calculating royalties and milestones due under this Agreement by no more than the average percentage discount of all products in a particular “bundle,” calculated as [1-(A/B)] x 100, where “A” equals the total discounted price of a particular “bundle” of products, and “B” equals the sum of the undiscounted bona fide list prices of each unit of every product in such “bundle”. Chelsea shall provide to DSP, to the extent reasonably available or ascertainable, documentation establishing such average discount with respect to each “bundle”. If Chelsea cannot so establish the average discount of a “bundle,” Net Sales for the “bundled” Licensed Product shall be based on (i) the median selling price of the Licensed Product alone during the applicable calendar quarter, if the Licensed Product is sold in a non-”bundled” form during such calendar quarter, or, if such Licensed Product is not sold in a non-”bundled” form during such calendar quarter, (ii) the undiscounted list price of the Licensed Product in the “bundle”. If a Licensed Product in a “bundle” is not sold separately, and/or no bona fide list price exists for such Licensed Product or the other products included in the “bundle,” then the Parties shall negotiate in good faith, based on a commercially reasonable determination of the relative values and/or imputed prices of the “bundled” product’s constituent products and Licensed Product, and imputed discounts provided with respect thereto, an alternative determination of Net Sales with respect to the Licensed Product included in such “bundled” product consistent with the intent of this Section 4.4.

4.5 Combination Products. In the event a Licensed Product is sold which is a Combination Product, for purposes of determining payments due under Section 4.3, Net Sales of Combination Products shall be calculated by multiplying the Net Sales of the Combination Product by the fraction A over A+B, in which A is the Gross Selling Price (as defined below) of the Licensed Product when such Licensed Product is sold in substantial quantities comprising L-DOPS as the sole therapeutically active ingredient during the applicable accounting period in which the Net Sales of the Licensed Product were calculated, and B is the Gross Selling Price of products incorporating solely the other therapeutically active ingredients contained in the Combination Product sold separately in substantial quantities during the applicable accounting period. In the event that no separate sale of either the Licensed Product comprising L-DOPS as the sole therapeutically active ingredient or products incorporating solely the other therapeutically active ingredients of the Combination Product are made during the accounting period in which the Net Sales were calculated, or if the Gross Selling Price for a product solely incorporating a particular therapeutically active ingredient cannot be determined for the applicable accounting period, Net Sales allocable to the Licensed Product and Combination Product shall be determined by mutual agreement reached in good faith by the Parties prior to the end of

the accounting period in question based on a reasonably equitable method of determining same that takes into account, in the Territory, variations in potency, the relative contribution of each therapeutically active ingredient in the Combination Product, and relative value to the end user of each therapeutically active ingredient. For purposes of this Section, “Gross Selling Price” shall mean the gross price at which a product incorporating such therapeutically active ingredient as the sole therapeutically active ingredient is sold to a Third Party, before discounts, deductions, credits, taxes or allowances.

4.6 Third Party Royalties. In the event that:

4.6.1 a Licensed Product, not to include Improvements or any future DSP’s Patents not existing as of the Effective Date, is deemed by a final, unappealable decision of a court of competent jurisdiction to infringe a claim of a patent(s) owned or controlled by a Third Party in any given country of the Territory, and Chelsea licenses such patent(s) in settlement of such claims (“Infringement License”), or

4.6.2 Chelsea determines, in its reasonable discretion, that it is commercially, reasonably necessary or advisable to pay royalties to a Third Party to obtain a license to practice any Third Party’s rights in order to Exploit a Licensed Product, not to include Improvements or any future DSP’s Patents not existing as of the Effective Date, in any given country of the Territory (“Necessary License”),

4.6.3 then Chelsea may deduct up to [*] percent ([*]%) of any fees, milestones, and royalties paid for such Infringement Licenses and Necessary Licenses due to such Third Parties (or such amounts paid by Chelsea in settlement of such infringement action) from the royalties otherwise due to DSP pursuant to Section 4.3 hereof, provided that the royalties to be paid by Chelsea pursuant to Section 4.3 shall be in no event less than [*] percent ([*]%) of Net Sales and provided that any additional amounts paid by Chelsea and not deducted shall be carried over to subsequent periods that royalties are due, and provided further that Chelsea shall provide DSP with detailed information on the Infringement Licenses and Necessary Licenses prior to obtaining such Infringement Licenses and Necessary Licenses.

4.7 Compulsory Licenses. Should a compulsory license be granted, or be the subject of a possible grant, to a Third Party under the applicable laws of any country in the Territory under the Licensed Patents licensed hereunder, Chelsea shall notify DSP, including any material information concerning such compulsory license, and the running royalty rate payable hereunder for sales of Licensed Products in such country shall be adjusted to match any lower royalty rate granted to such Third Party for such country with respect to the sales of such Licensed Products to the extent the Licensed Patents cover the Licensed Product, provided that during such periods such Third Parties sell or offer for sale under the compulsory license articles that compete with the Licensed Products then marketed and sold by Chelsea in that country.

4.8 Generic Competition. If the Licensed Product does not receive or maintain the Orphan Drug Designation in the USA, through no fault of Chelsea, its

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

Affiliates or Sublicensees, and during the Term, there is Generic Competition in the country, then, on a Licensed Product-by-Licensed Product basis, the royalty to be paid on the Net Sales of the Licensed Product in the USA pursuant to Section 4.3, as it may be adjusted or affected by Sections 4.3, 4.5, and 4.6, will be reduced by [*] percent ([*]%).

4.9 Net Sales Report. Within sixty (60) days following the end of each calendar quarter following the First Commercial Sale in the Territory, Chelsea shall submit to DSP a written report setting forth Net Sales in the Territory on a country-by-country basis and Licensed Product-by-Licensed Product basis during such calendar quarter and calendar year-to-date, total royalty and milestone payments due to DSP, relevant sales and pricing data in support of royalties paid on Licensed Product sold as a “bundle” and Combination Products, and relevant information as necessary to support any reduction in royalties paid resulting from the application of Section 4 hereof. Net Sales reporting shall terminate upon expiration of the obligations of Chelsea to pay royalties pursuant to Section 4.3.

4.10 Payment Terms. Except as otherwise set forth herein, all sums due to DSP shall be payable in United States dollars.

During normal business hours and with reasonable advance written notice to Chelsea, such records shall be made available for inspection, review and audit, at the request of DSP, by an independent certified public accountant appointed by DSP and reasonably acceptable to Chelsea for the purpose of verifying the accuracy of accounting reports and payments pursuant to this Agreement.

year and the right to audit shall terminate one (1) calendar year after expiration of the obligations of Chelsea to pay royalties pursuant to Section 4.3. All costs and expenses incurred in performing any such audit shall be paid by DSP unless the audit discloses at least a five percent (5%) shortfall in payments made with respect to a calendar quarter, in which case Chelsea shall bear the reasonable, documented cost of the audit. DSP shall be entitled to recover any shortfall in payments as determined by such audit and Chelsea shall pay such shortfall to DSP in such manner as mutually agreed upon by the Parties.

6.1 Prosecution and Maintenance of Licensed Patents. DSP shall file, prosecute (including but not limited to, by conducting interferences, oppositions and reexaminations or other similar proceedings), and maintain (by timely paying all maintenance fees, renewal fees and other applicable fees and costs) all Licensed Patents in such countries of the Territory as agreed upon between the Parties. DSP shall keep Chelsea informed of the updated situation relating to the Licensed Patents. Chelsea shall cooperate with DSP so far as reasonably necessary with respect to furnishing all information and data in its possession reasonably necessary to obtain or maintain such Licensed Patents. DSP shall have no obligation to file, prosecute (including but not limited to, by conducting interferences, oppositions and reexaminations or other similar proceedings), and maintain (by timely paying all maintenance fees, renewal fees and other applicable fees and costs) any Licensed Patents in the other countries of the Territory, provided that, if requested by Chelsea, DSP shall conduct those actions under the name of DSP at the expense of Chelsea and the relevant Licensed Patents shall be owned by DSP. Upon expiration or termination (not including any termination by DSP pursuant to Section 8.2 or 8.3 and by Chelsea pursuant to Section 8.4) of this Agreement, Chelsea shall have a perpetual, irrevocable, royalty-free exclusive right to use such Licensed Patents, Licensed Know-How and Improvements solely in connection with Exploiting L-DOPS in the Territory after the Term of this Agreement

6.2 Patent Infringement.

6.2.1 Infringement Claims. With respect to any and all Claims instituted by Third Parties against Chelsea, DSP, or any of their respective Affiliates for patent infringement involving the manufacture, use, license, marketing or sale of a Licensed Product during the Term (each, a “Patent Infringement Claim”), DSP and Chelsea shall assist one another and cooperate in the defense and settlement of such Patent Infringement Claims at the other Party’s request.

6.2.2 Infringement of Patents.

(a) In the event that Chelsea or DSP becomes aware of actual or threatened infringement of a Licensed Patent, within the Licensed Field in the Territory during the Term, that Party shall promptly notify the other Party in writing, which notice shall include any known material details concerning such infringement. Chelsea shall have the first right, but not the obligation, to bring an infringement action against any Third Party in respect of such Licensed Patent. If Chelsea elects to pursue such infringement action, Chelsea shall be solely responsible for the costs and expenses associated with such action and all recoveries (including settlements) shall be applied as follows: (i) first to reimburse Chelsea for any reasonable, documented expenses incurred in respect of such action; (ii) second, to reimburse DSP for any reasonable, documented expenses incurred in respect of such action; and (iii) any remaining amounts shall be allocated as follows: (a) any amounts attributable to lost profits shall be treated as Net Sales, and Chelsea shall pay to DSP royalties due on such amounts in accordance with Section 4 of this Agreement; and (b) any amounts not attributable to lost profits shall be allocated on the basis of [*] percent ([*]%) to DSP and [*] percent ([*]%) to Chelsea.

(b) During the Term, in the event that Chelsea does not undertake an infringement action under Section 6.2.2(a), upon Chelsea’s written consent, which shall not be unreasonably withheld, refused, conditioned or delayed, DSP shall be permitted to undertake an infringement action, at DSP’s sole expense, and, if required, in the relevant Party’s name or the relevant Party’s Affiliate’s name and on the relevant Party’s or the relevant Party’s Affiliate’s behalf. If a particular Party is attempting to undertake an infringement action pursuant to this Section 6.2.2, but such Party is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then such Party may join the other Party as a party-plaintiff. If DSP elects to pursue such infringement action, DSP may be represented in such action by attorneys of its own choice and at its own expense, with DSP taking the lead in such action. In the event that DSP brings any such action after Chelsea has elected not to pursue such action, DSP shall be solely responsible for the costs and expenses associated with such action and all recoveries (including settlements) shall be applied as follows: (i) first to reimburse DSP for any expenses incurred in respect of such action; (ii) second, to reimburse Chelsea for any expenses incurred in respect of such action; and (iii) (a) any amounts attributable to lost profits shall be treated as Net Sales, and Chelsea shall pay to DSP royalties due on such amounts in accordance with Section 4 of this Agreement; and (b) any amounts not attributable to lost profits shall be allocated on the basis of [*] percent ([*]%) to DSP and [*] percent ([*]%) to Chelsea.

6.3 Assistance. For purposes of this Section 6, the Party not bringing suit or defending any suit shall execute such legal papers necessary for the prosecution or defense of such suit as may be reasonably requested by the Party bringing suit or defending any suit. The reasonable, documented out-of-pocket costs and expenses of the Parties shall be reimbursed out of any damages, settlements or other monetary awards recovered as set forth in Section 6.2.2. Any remaining damages, settlements or other monetary awards shall be divided as specified in Section 6.2.2. No settlement, consent judgment or other voluntary final disposition of a suit under this Section 6 may be entered into by a Party without the joint written consent of the other Party (which consent shall not be unreasonably withheld, delayed, or conditioned).

7. Supply.

7.1 Clinical Supply. DSP shall supply Chelsea with all of Chelsea’s requirements of the Compound for use in clinical trials. The price of the Compound supplied to Chelsea hereunder for clinical use shall be Japanese Yen [*] ([*]) per kilogram on the basis of FCA Kansai International Airport in Japan, as defined by INCOTERMS 2000 as amended. Sections 4 and 7 of the License Agreement shall apply mutatis mutandis to delivery of and payment for the Compound for clinical use hereunder.

7.2 Commercial Supply. DSP shall supply Chelsea with all of Chelsea’s requirements of the Compound for commercial use on such terms and conditions as provided for in the Supply Agreement (the “Supply Agreement”) attached hereto as Exhibit F, which shall become effective upon the dosing of the first patient in Chelsea’s Phase III Clinical Trial using a Licensed Product. The Supply Agreement shall be an integral part of this Agreement, and in case of conflict between this Agreement and the Supply Agreement, this Agreement shall prevail.

The Compound for commercial supply shall be sold to Chelsea at such price in Japanese Yen as agreed upon between the Parties pursuant to the Supply Agreement on the basis of FCA Kansai International Airport in Japan, as defined by INCOTERMS 2000 as amended.

In the event such supply price for commercial supply exceeds an average price (excluding any special or time-limited discount prices) quoted by a Third Party to Chelsea for the Compound with substantially similar specifications (the “Market Price”) to the Compound supplied by DSP as determined by the Joint Committee, Chelsea and DSP shall discuss in good faith the possibility of reduction of the supply price to the level of the Market Price. In the event Chelsea and DSP do not agree to the reduction of the supply price within one hundred twenty (120) days of the commencement of negotiations as a result of a good faith dispute, then Chelsea may use the Compound manufactured by itself or its designee reasonably acceptable to DSP, which acceptance shall not be unreasonably withheld or delayed, and the royalty paid by Chelsea pursuant to Section 4.3 shall increase by one percent (1%) with respect to the Net Sales of Licensed Products containing the Compound not supplied by DSP. The Parties recognize that in the case Chelsea may use the Compound manufactured by itself or its designee, Chelsea will need substantial time and resources to prepare for such case and therefore, Chelsea may initiate its preparation for manufacture of the Compound, including but not limited to selection of candidates of its designated manufacturer, before Chelsea has the right to use the Compound manufactured by it or its designee hereunder, provided that DSP shall have no obligation to provide its Know-How on manufacturing of the Compound to Chelsea or Chelsea’s designee for the purpose of such Chelsea’s preparation.

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

Notwithstanding the foregoing, in the event (i) any facility involved in the manufacture or storage of the Compound hereunder is prohibited from, or materially adversely affected in its ability to, produce, store, or otherwise be involved in the provision of the Compound to Chelsea under this Agreement by the appropriate Regulatory Authorities or due to such failure to comply; or (ii) the termination of the Supply Agreement by Chelsea pursuant to Section 11.3 or 11.4 of the Supply Agreement (each a “Back-up Trigger”), DSP shall provide to Chelsea the reasonable Know-How necessary to manufacture the Compound so that Chelsea may manufacture the Compound by itself or its designee reasonably acceptable to DSP and there shall be no such increase in royalty. In case of the occurrence of the Back-up Trigger described in (i) above, Chelsea and DSP shall discuss in good faith and determine (i) the estimated period that DSP cannot supply the Compound and (ii) the quantity of the Compound which DSP cannot supply during the estimated period, and during such estimated period, Chelsea may manufacture the Compound by itself or its designee or procure the Compound from any third party. If, after such estimated period, DSP can demonstrate to Chelsea that it has cured the event giving rise to such Back-Up Trigger and is able to supply to Chelsea, on a long-term basis, the Compound in accordance with the Supply Agreement, then Chelsea shall, recommence the purchase of the Compound from DSP.

8. Term and Termination.

8.1 Term. Unless otherwise mutually agreed to by the Parties or earlier terminated as provided herein, this Agreement shall continue in effect for the Term.

8.2 Termination for Material Breach. Either Party may, without prejudice to any other remedies available to it at law or in equity, terminate this Agreement in the event that the other Party materially breaches its obligations under this Agreement; provided that, if such breach can be cured, the breaching Party shall have sixty (60) days after receipt of written notice thereof from the non-breaching Party to cure such breach. Any such termination shall become effective at the end of such 60-day period unless the breaching Party has cured any such breach prior to the expiration of such 60-day period (or, if such breach is capable of being cured but cannot be cured within such 60-day period, the breaching Party has commenced and used diligent efforts to cure such breach, provided that, in such instance, such cure must have occurred within one hundred twenty (120) days after receipt of written notice thereof from the non-breaching Party).

8.3 Termination for Bankruptcy. This Agreement may be terminated by either Party within thirty (30) days upon written notice in case the other Party makes an assignment for the benefit of creditors or become involved in receivership, bankruptcy (but excluding Chapter 11 bankruptcy under the U.S. Bankruptcy Act, and the Japanese Civil Rehabilitation Law and the Japanese Corporate Reorganization Law) or other insolvency or debtor relief proceedings, or any similar proceedings, or in proceedings, voluntary or forced, whereby the other Party is limited in the free and unrestrained exercise of its own judgment as to the carrying out of the terms of this Agreement.

8.4 Termination by Chelsea. Chelsea may terminate this Agreement at any time for its convenience by providing DSP with sixty (60) days prior written notice containing the rationale of the termination.

8.5 Effects of Termination.

8.5.1 Effect of Termination for Material Breach.

(a) Material Breach by Chelsea. In the event this Agreement is terminated by DSP pursuant to Section 8.2 for material breach by Chelsea, all licenses and rights granted by DSP to Chelsea or its Affiliates under this Agreement shall terminate.

(b) Material Breach by DSP. In the event this Agreement is terminated by Chelsea pursuant to Section 8.2 for material breach by DSP, all licenses and rights granted by DSP to Chelsea or its Affiliates under this Agreement prior to termination shall survive, and all of the licenses and rights granted to Chelsea under this Agreement shall become irrevocable, perpetual and royalty-free, subject to Chelsea’s continued obligation to pay milestones hereunder.

8.5.2 Effect of Termination by Chelsea.

8.5.3 Sublicenses. If this Agreement is terminated by DSP for Chelsea’s breach, pursuant to Section 8.2, all sublicenses and rights with Third Parties regarding the licenses and rights hereunder granted to Chelsea by DSP hereunder prior to such termination shall be automatically assigned to DSP upon such termination, subject to the payment of any amounts due thereunder to DSP, in order to permit such Sublicensees’ continued quiet enjoyment of their rights thereunder in accordance with the terms thereof; provided, however, that such assignment shall not subject DSP to any obligations or liabilities in excess of those imposed by this Agreement.

8.6 Accrued Rights; Surviving Obligations. Except as provided elsewhere, termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination or expiration. Such termination or expiration shall not relieve any Party from obligations that are expressly or by implication intended to survive termination or expiration of this Agreement, including but not limited to, definitions, rights to payment, and Sections 3.3, 3.4, 4.10, 4.11, 8.5, 8.6, 9, 10 and 11.4 and shall not affect or prejudice any provision of this Agreement which is expressly or by implication provided to come into effect on, or continue in effect after, such termination or expiration. Notwithstanding anything herein to the contrary, all rights granted to the data under Section 3.4 shall survive.

9. Confidential Information.

9.1 Definition. “Confidential Information” means confidential or proprietary information, data or know-how, whether provided in written, oral, visual or other form, provided by one Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) in connection with this Agreement, including but not limited to, the terms of this Agreement and information relating to the Disclosing Party’s existing or proposed research, development efforts, patent applications, business or products. Confidential Information shall not include any such information to the extent that the information: (i) is already known to the Receiving Party (other than under an obligation of confidentiality) at the time of disclosure (as evidenced by written records of the Receiving Party); (ii) is or becomes generally available to the public other than through any act or omission of the Receiving Party; (iii) is disclosed to the Receiving Party without obligation of confidentiality by a Third Party who had the legal right to disclose such information; or (iv) is independently discovered or developed by or on behalf of the Receiving Party without the use or benefit of the Confidential Information of the Disclosing Party (as evidenced by written records of the Receiving Party).

9.2 Confidentiality. The Receiving Party shall keep in confidence all Confidential Information of the Disclosing Party with the same degree of care it employs to maintain the confidentiality of its own Confidential Information, but no less than a reasonable degree of care. The Receiving Party shall not use such Confidential Information for any purpose other than in performance of or exercise of its rights or obligations under this Agreement or disclose the same to any other Person other than to the Receiving Party’s and its Affiliates’ (and, if applicable, the Sublicensees’) employees, agents, or subcontractors who have a need to know such Confidential Information to implement the terms of or exercise of the Receiving Party’s rights or obligations under this Agreement. The Receiving Party shall advise any employee, agent or subcontractor who receives Confidential Information of the Receiving Party’s obligations, and the Receiving Party shall ensure that all such agents, employees and subcontractors comply with such obligations as if they had been a Party hereto. The Receiving Party shall be liable for breach of this Section 9 by any of its employees, agents or subcontractors.

9.3 Permitted Disclosure and Use. The Receiving Party shall have the right to disclose Confidential Information if, in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is required by Law or the rules of any stock exchange, provided that, to the extent reasonably practicable, the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party to permit the Disclosing Party to intervene and to request protective orders or other confidential treatment. The Receiving Party shall cooperate reasonably with any such efforts by the Disclosing Party.

9.4 Confidentiality of this Agreement. The terms of this Agreement shall be deemed Confidential Information of each Party. Either Party may disclose the

terms of this Agreement: (i) if, in the opinion of its counsel, such disclosure is required by Law, provided that such Party shall seek appropriate confidentiality of those portions of the Agreement for which confidential treatment or a protective order is typically permitted by the relevant Governmental Authority; or (ii) as necessary in connection with any financing, merger, strategic partnership, or other similar transaction, subject to the execution of a confidentiality agreement with the applicable Third Party that receives the information and terms.

9.5 Return. Unless otherwise provided for in this Agreement, upon termination of this Agreement, the Receiving Party shall return all documents or other media containing Confidential Information of the Disclosing Party, except that each Party may retain one copy of all Confidential Information solely for establishing its obligations under the Agreement.

9.6 Remedies. Money damages shall not be an adequate remedy if this Section 9 is breached and, therefore, either Party may, in addition to any other legal or equitable remedies, be entitled to seek an injunction or other equitable relief against such breach or threatened breach without the necessity of posting any bond or surety.

9.7 Survival. This Section 9 shall survive the expiration or termination of this Agreement for a period of ten (10) years.

10. Indemnification.

10.1 Indemnification by Chelsea. Subject to Sections 10.3 and 10.4, Chelsea shall defend, indemnify and hold harmless DSP and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns from and against all Claims of Third Parties, and all associated losses damages, claims, payments (collectively, “Losses”), to the extent arising out of: (i) Chelsea’s negligence or willful misconduct in performing any of its obligations or exercising its rights under this Agreement; (ii) breach by Chelsea of any of its representations, warranties, covenants, or agreements under this Agreement; or (iii) the Exploitation of Licensed Products by Chelsea, its Affiliates, agents, subcontractors or Sublicensees, except to the extent resulting from the negligence or willful misconduct, breach of this Agreement, or failure to comply with applicable Laws by DSP or its Affiliates, sublicensees, officers, directors, employees, contractors, agents, other representatives, successors, or assigns.

10.2 Indemnification by DSP. Subject to Sections 10.3 and 10.4, DSP shall defend, indemnify and hold harmless Chelsea and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns from and against all Claims of Third Parties, and all associated Losses, to the extent arising out of: (i) DSP’s negligence or willful misconduct in performing any of its obligations or exercising its rights under this Agreement; (ii) breach by DSP of any of its representations, warranties, covenants or agreements under this Agreement; or (iii) the Exploitation of Improvements by DSP, its Affiliates, agents, subcontractors or Sublicensees, except to the extent resulting from the negligence or willful misconduct, breach of this Agreement, or failure to comply with applicable Laws by Chelsea or its Affiliates, sublicensees, officers, directors, employees, contractors, agents, other representatives, successors, or assigns.

10.3 Procedure for Indemnification. A Party which intends to seek indemnification under this Section 10 (such Party hereinafter referred to as the “Indemnitee”) for a Loss in respect to a Claim by a Third Party (“Third Party Claim”), shall promptly give written notice thereof to the Party from whom indemnification is sought (such other Party hereinafter referred to as the “Indemnitor”) within a reasonable period of time after the assertion of such Third Party Claim; provided, however, that the failure to provide written notice of such Third Party Claim within a reasonable period of time shall not relieve Indemnitor of any of its obligations hereunder, except to the extent that Indemnitor is materially prejudiced by such failure. Indemnitor may assume the complete control of the defense, compromise or settlement of any Third Party Claim (provided that any settlement of any Third Party Claim that: (i) subjects Indemnitee to any non-indemnified liability; or (ii) admits fault or wrongdoing on the part of Indemnitee shall require the prior written consent of such Indemnitee, provided such consent shall not be unreasonably withheld), including, at its own expense, employment of legal counsel, and at any time thereafter Indemnitor shall be entitled to exercise, on behalf of Indemnitee, any rights which may mitigate the extent or amount of such Third Party Claim; provided, however, that if Indemnitor shall have exercised its right to assume control of such Third Party Claim, Indemnitee (x) may, in its sole discretion and at its own expense, employ legal counsel to represent it (in addition to the legal counsel employed by Indemnitor) in any such matter, and in such event legal counsel selected by Indemnitee shall be required to confer and cooperate with the counsel of Indemnitor in such defense, compromise or settlement for the purpose of informing and sharing information with Indemnitor; (y) shall, at Indemnitor’s own expense, make available to Indemnitor those employees, officers, contractors, and directors of Indemnitee whose assistance, testimony or presence is necessary or appropriate to assist Indemnitor in evaluating and in defending any such Third Party Claim; provided, however, that any such access shall be conducted in such a manner as not to interfere unreasonably with the operations of the businesses of Indemnitee; and (z) shall otherwise fully cooperate with Indemnitor and its legal counsel in the investigation and defense of such Third Party Claim.

10.4 Consequential Damages. IN NO EVENT SHALL EITHER PARTY OR ITS AFFILIATES BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE, TREBLE OR CONSEQUENTIAL DAMAGES INCLUDING LOST PROFITS, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER LEGAL THEORY.

11. Miscellaneous.

11.1 Public Announcements. Except as may be expressly permitted under this Section 11.1 or required by applicable Laws or the rules of any stock exchange, neither Party shall make any public announcement of any information regarding this Agreement without the prior written approval of the other Party, which approval shall not be unreasonably withheld, conditioned, or delayed, subject to prior written notice to the other Party. To the extent reasonably practicable, each Party shall

submit to the other Party any proposed announcements at least ten (10) business days prior to the intended date of publication of such announcement to permit review and the other Party shall provide its comments in writing within five (5) business days after receipt of the proposed announcement. The Party shall complete the announcement, taking the other Party’s comments into due consideration. Once any statement is approved for disclosure by the Parties or information is otherwise made public in accordance with the preceding sentence, either Party may make a subsequent public disclosure of the specific contents of such statement without further approval of the other Party.

11.2 Relationship of the Parties. Each Party shall bear its own costs incurred in the performance of its obligations hereunder without charge or expense to the other except as expressly provided in this Agreement. Neither Party shall have any responsibility for the hiring, termination or compensation of the other Party’s employees or for any employee benefits of such employees. No employee or representative of a Party shall have any authority to bind or obligate the other Party to this Agreement in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without such Party’s approval. For all purposes, Chelsea’s legal relationship under this Agreement to DSP shall be that of independent contractor. This Agreement is not a partnership agreement and nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

11.3 Force Majeure. The occurrence of an event which materially interferes with the ability of a Party to perform its obligations or duties hereunder, which is not within the reasonable control of the Party affected (including any of its Affiliates and Sublicensees), and which could not with the exercise of due diligence have been avoided (“Force Majeure Event”), including but not limited to, fire, accident, strike, riot, civil commotion, act of God, inability to obtain raw materials, delay or errors by shipping companies or change in law, shall not excuse such Party from the performance of its obligations or duties under this Agreement, but shall merely suspend such performance during the Force Majeure Event. The Party subject to a Force Majeure Event shall promptly notify the other Party of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to time, with its best estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so affected shall use commercially reasonable efforts to avoid or remove such causes of nonperformance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty shall promptly recommence. The Party subject to the Force Majeure Event shall not be liable to the other Party for any direct, indirect, consequential, incidental, special, punitive, exemplary or other damages arising out of or relating to the suspension or termination of any of its obligations or duties under this Agreement by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 11.3.

11.4 Governing Law and Arbitration. This Agreement shall be governed by and construed and enforced in accordance with the laws of England, excluding that body of law known as choice of law, and shall be binding upon the

Parties in the United States and worldwide. All disputes with respect to this Agreement which cannot be solved amicably between the Parties shall be finally settled by arbitration held in the English language in accordance with the Rules of Arbitration of International Chamber of Commerce. The arbitration shall be held in Osaka, Japan if the arbitration is initiated by Chelsea and in Charlotte, North Carolina, USA if the arbitration is initiated by DSP. The award rendered by the arbitration shall in any case be final and binding upon the Parties hereto. Judgment upon the award may be entered in any court having jurisdiction thereof.

11.5 Assignment. This Agreement may not be assigned by either Party without the prior written consent of the other Party; provided that either Party may assign this Agreement, in whole or in part, to any of its Affiliates if such Party guarantees the performance of this Agreement by such Affiliate; and provided further that either Party may assign this Agreement to a successor to all or substantially all of the assets or business of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or other similar transaction. In any event, the assigning Party shall provide the other Party with ten (10) business days’ prior written notice of assignment. Any assignment in violation of this provision is void and without effect. This Agreement shall be binding upon and inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns.

FORM OF

SUBSCRIPTION AGREEMENT

SUBSCRIPTION AGREEMENT

THIS SUBSCRIPTION AGREEMENT (this “Agreement”) made as of the date set forth on the signature page hereof between Chelsea Therapeutics International, Ltd., a Delaware corporation having a place of business at ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ (the “Company”), and Dainippon Sumitomo Pharma Co., Ltd., a Japanese corporation having a place of business at 6-8 ▇▇▇▇▇▇▇▇▇▇ ▇-▇▇▇▇▇, ▇▇▇▇-▇▇, ▇▇▇▇▇ ▇▇▇-▇▇▇▇, ▇▇▇▇▇ (the “Subscriber”).

W I T N E S S E T H:

WHEREAS, the Company’s wholly owned subsidiary Chelsea Therapeutics, Inc. and the Subscriber are entering into an Exclusive License Agreement (the “License”) for L-DOPS, as defined therein, under which the Company is to issue to the Subscriber shares (the “Shares”) of its common stock, par value $0.0001 per share (“Common Stock”); and

WHEREAS, on the terms and conditions hereinafter set forth, the Subscriber desires to purchase from the Company, and the Company desires to sell to the Subscriber, a number of Shares.

NOW, THEREFORE, in consideration of the promises and the mutual representations and covenants hereinafter set forth, the parties hereto do hereby agree as follows:

1. PURCHASE AND SALE OF SHARES.

1.1 The number of Shares to be issued hereunder shall be , which is equal to U.S. $250,000 provided for in Section 4.1 of the License or U.S. $[*] provided for in Section 4.2 of the License divided by the average closing price of the Company’s Common Stock as reported on NASDAQ for the ten (10) trading days prior to the Effective Date (as defined in the License) or the date of the corresponding milestone in the License. The consideration for the Shares shall be the Subscriber’s execution and delivery of the License.

1.2 The closing hereunder (the “Closing”) shall be held at a date and time designated by the Company and the Subscriber pursuant to the License which date shall be no later than five (5) business days after satisfaction or waiver of the closing conditions set forth in Article 4 hereof. The Closing shall occur at the offices of the Company or such other place as may be agreed upon between the parties.

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

1.3 The Company shall deliver, or cause to be delivered, the certificates representing the Shares purchased by the Subscriber hereunder as soon as practical after the Closing to the Subscriber’s address indicated on the signature page hereto, provided that the Company shall provide the Subscriber with such evidence as the Subscriber may reasonably request evidencing that the Subscriber’s rights as the holder of the Shares commence as of and from the Closing Date.

2. REPRESENTATIONS AND WARRANTIES OF SUBSCRIBER.

The Subscriber hereby represents and warrants to the Company as of the date hereof and the Closing Date as follows:

2.1 The Subscriber understands, acknowledges and agrees that the purchase of the Shares involves a high degree of risk including, but not limited to, the following: (i) an investment in the Company is highly speculative, and only investors who can afford the loss of their entire investment should consider investing in the Company and the Shares; (ii) the Subscriber may not be able to liquidate its investment; (iii) transferability of the Shares is extremely limited; (iv) in the event of a disposition of the Shares, the Subscriber could sustain the loss of its entire investment; and (v) since the Company has been a publicly traded company, the Company has not paid any dividends on its Common Stock and does not anticipate the payment of dividends in the foreseeable future.

2.2 The Subscriber is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”).

2.3 The Subscriber understands, acknowledges and agrees that: (i) the Subscriber is knowledgeable, sophisticated and has experience in making, and is qualified to make, decisions with respect to investments representing an investment decision like that involved in the purchase of the Shares and has prior investment experience, including investments in securities which are non-listed, unregistered and/or not traded on the New York Stock Exchange, AMEX, the Nasdaq National Market or Capital Market or any other national stock exchange; (ii) the market price of the Common Stock has been and continues to be volatile and the Subscriber has carefully evaluated the risks of an investment in the Shares; and (iii) the Subscriber is able to bear the economic risk of an investment in the Shares and the potential loss of such investment, which risk the Subscriber hereby assumes.

2.4 The Subscriber has received and reviewed this Agreement and documents filed by the Company with the Securities and Exchange Commission (the “SEC”, and such documents, the “SEC Filings”). For purposes of this representation, the parties agree that any information that that Company subsequently files with the SEC shall automatically update and supersede any previous information, provided that the Subscriber has been provided a copy of such SEC Filings or provides access to an automated service to provide such notification by e-mail. The Subscriber further represents that it has been furnished by the Company during the course of this

transaction with all information regarding the Company which the Subscriber, its investment advisor, attorney and/or accountant has requested or desired to know or which is otherwise relevant to an investment decision, has been afforded the opportunity to ask questions of and receive answers from duly authorized officers or other representatives of the Company concerning the terms and conditions hereof and has received any additional information which the Subscriber or its advisors or agents has requested.

2.5 (a) The Subscriber has relied solely upon the information provided by the Company in making the decision to invest in the Shares. In evaluating the suitability of an investment in the Company, the Subscriber has not relied upon any representation or other information (whether oral or written) from the Company, or any agent, employee or Affiliate of the Company other than as set forth in this Agreement or resulting from the Subscriber’s own independent investigation. The Subscriber understands and acknowledges that nothing in this Agreement or any other materials provided to the Subscriber in connection with the subscription for the Shares or sale of the Shares constitutes investment, tax or legal advice. To the extent deemed necessary or advisable by the Subscriber in its sole discretion, the Subscriber has retained, at its sole expense, and relied upon appropriate professional advice regarding the investment, tax and legal merits and consequences of this Agreement and its purchase of the Shares hereunder.

(b) No Shares were offered or sold to the Subscriber by means of any form of general solicitation or general advertising.

2.6 The Subscriber, either by reason of the Subscriber’s business or financial experience or the business or financial experience of the Subscriber’s professional advisors, has the capacity to protect the Subscriber’s own interests in connection with the transaction contemplated hereby.

2.7 The Subscriber understands, acknowledges and agrees that the issuance of the Shares hereunder has not been reviewed, recommended or endorsed by the SEC or any other securities regulatory authority or other governmental body or agency, since it is intended to be exempt from the registration requirements of Section 5 of the Securities Act pursuant to Regulation D promulgated under the Securities Act. The Subscriber shall not sell or otherwise transfer the Shares unless such transfer is registered under the Securities Act or unless an exemption from such registration is available. The Subscriber understands that if required by the laws or regulations or any applicable jurisdictions, the offering contemplated hereby shall be submitted to the appropriate authorities of such state(s) for registration or exemption therefrom.

2.8 The Subscriber understands, acknowledges and agrees that the Shares have not been registered under the Securities Act in reliance upon a claimed exemption under the provisions of the Securities Act which depends, in part, upon the Subscriber’s investment intention and the truth and accuracy of, and Subscriber’s compliance with, the representations, warranties, acknowledgments and covenants of Subscriber set forth herein. In this connection, the Subscriber hereby represents that the representations, warranties, acknowledgments and covenants of Subscriber set forth

herein are true and correct, the Subscriber shall comply with the covenants set forth herein, and the Subscriber is purchasing the Shares for the Subscriber’s own account for investment purposes only and not with a view toward the resale or distribution to others and has no contract, undertaking, agreement or other arrangement, in existence or contemplated, to sell, pledge, assign or otherwise transfer the Shares to any other person. The Subscriber also represents that it was not formed for the purpose of purchasing the Shares. The Subscriber has no current plans to effect a “change of control” of the Company, as such term is understood in Rule 13d-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

2.9 The Subscriber understands that the Shares shall not be registered or available for sale in the public markets except as specifically provided herein, and Rule 144 promulgated under the Securities Act requires, among other conditions, a one-year holding period prior to the resale (in limited amounts) of Shares acquired in a non-public offering (and a two-year holding period for unlimited sales by non-Affiliates of the Company) without having to satisfy the registration requirements under the Securities Act. The Subscriber understands and hereby acknowledges that the Company is under no obligation to register any of the Shares under the Securities Act or any other applicable securities or “blue sky” laws.

2.10 The Subscriber consents to the placement of a legend on any certificate or other document evidencing the Shares substantially as set forth below, that such Shares have not been registered under the Securities Act or any other applicable securities or “blue sky” laws and setting forth or referring to the restrictions on transferability and sale thereof contained in this Agreement. The Subscriber is aware that the Company shall make a notation in its appropriate records with respect to the restrictions on the transferability of the Shares.

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF ANY OTHER JURISDICTION. THESE SHARES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER THE SECURITIES ACT AND APPLICABLE SECURITIES LAWS, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND SCOPE REASONABLY SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED.

2.11 The address of the Subscriber furnished by the Subscriber on the signature page hereof is the Subscriber’s principal business address.

2.12 The Subscriber has full power and authority (corporate or otherwise) to execute, deliver, and perform this Agreement and to purchase the Shares and has taken all action necessary to authorize the execution, delivery and performance

of this Agreement. This Agreement constitutes the legal, valid and binding obligation of the Subscriber, enforceable against the Subscriber in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other equitable remedies, and to limitations of public policy.

2.13 The Subscriber (a) is authorized and qualified to become an investor in the Company and the person signing this Agreement on behalf of such entity has been duly authorized by such entity to do so and (b) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization.

2.14 No authorization, approval, consent or license of any person is required to be obtained for the purchase of the Shares by the Subscriber, other than as have been obtained and are in full force and effect. The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby shall not, result in any violation of or constitute a default under any material agreement or other instrument to which the Subscriber is a party or by which the Subscriber or any of its properties are bound, or to the best of the Subscriber’s knowledge, any permit, franchise, judgment, order, decree, statute, rule or regulation to which the Subscriber or any of its businesses or properties is subject.

3 REPRESENTATIONS BY AND COVENANTS OF THE COMPANY.

The Company hereby represents and warrants to the Subscriber as of the date hereof and the Closing Date that:

3.1 The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and has full corporate power and authority to conduct its business as currently conducted. The Company is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which such qualification is necessary, except to the extent that the failure to be so qualified or in good standing would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, operations, conditions (financial or otherwise), assets or results of operations of the Company and its subsidiaries as a whole (a “Material Adverse Effect”). The Company is not the subject of any pending or, to its knowledge, threatened investigation or administrative or legal proceeding in any state, federal or local jurisdiction.

3.2 (a) The authorized capital stock of the Company consists of 50,000,000 shares of capital stock, of which 45,000,000 are designated Common Stock and 5,000,000 of which are designated preferred stock.

In addition, there are 4,927,880 shares of Common Stock reserved for issuance pursuant to outstanding options and warrants. All of the Shares issued by the Company have been issued in accordance with all applicable federal and other securities laws. Other than as set forth above, there are no other options, warrants, calls,

rights, commitments or agreements of any character to which the Company is a party or by which the Company is bound or obligating the Company to issue, deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any shares of the capital stock of the Company or obligating the Company to grant, extend or enter into any such option, warrant, call, right, commitment or agreement. There are no preemptive rights or rights of first refusal or similar rights which are binding on the Company permitting any person to subscribe for or purchase from the Company shares of its capital stock pursuant to any provision of law, the Company’s Certificate of Incorporation or the Company’s By-laws, or pursuant to any agreement, contract or understanding to which the Company is a party. There are no shares or instruments containing anti-dilution or similar provisions that shall be triggered by the issuance of the Shares as described in this Agreement. Except as set forth in the SEC Filings, the Company does not own, directly or indirectly, any stock, partnership interest, joint venture interest or any other equity interest in, or security issued by, any person.

(b) The Shares have been duly authorized and, when issued, delivered and paid for in the manner set forth in this Agreement, shall be duly authorized, validly issued, fully paid and non-assessable. No further approval or authority of the stockholders or the Board of Directors of the Company shall be required for the issuance and sale of the Shares to be sold by the Company as contemplated herein.

3.3 The Company has all power and authority (corporate or otherwise) to enter into this Agreement and to consummate the transactions contemplated hereby. All corporate action on the part of the Company, its directors and stockholders necessary for the authorization, execution, delivery and performance of this Agreement by the Company, the authorization, sale, issuance and delivery of the Shares contemplated herein and the performance of the Company’s obligations hereunder has been taken. This Agreement has been duly executed and delivered by the Company and constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other equitable remedies, and to limitations of public policy.

3.4 (a) The execution and delivery by the Company of this Agreement and the consummation of the transactions contemplated hereby shall not result in the violation of any law, statute, rule, regulation, order, writ, injunction, judgment or decree of any court or Governmental Authority to or by which the Company or any subsidiary thereof is bound, or of any provision of the Certificate of Incorporation or By-Laws of the Company, and shall not conflict with, or result in a breach or violation of, any of the terms or provisions of, or constitute (with due notice or lapse of time or both) a default under, any lease, loan agreement, mortgage, security agreement, trust indenture or other agreement or instrument to which the Company or any subsidiary thereof is a party or by which it is bound or to which any of its properties or assets is subject, nor result in the creation or imposition of any lien upon any of the properties or assets of the Company or any subsidiary thereof where such violation, breach, default or imposition would reasonably be likely to result in a Material Adverse Effect.

(b) No material consent, approval, authorization or other order of any Governmental Authority or other third-party is required to be obtained by the Company or any subsidiary thereof in connection with the authorization, execution and delivery of this Agreement or with the authorization, issue and sale of the Shares, except such filings as may be required to be made with the SEC, any stock exchange or quotation service and with any state or foreign blue sky or securities regulatory authority.

3.5 All reports required to be filed by the Company since January 1, 2005 under the Exchange Act have been duly filed with the SEC, complied at the time of filing in all material respects with the requirements of their respective forms and the rules and regulations thereunder, except to the extent updated or superseded by any subsequently filed report, were complete and correct in all material respects as of the dates at which the information was furnished, and such reports did not contain (as of their respective dates) any untrue statements of a material fact nor omitted to state any material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading, or if amended, as so amended.

3.6 Neither the Company nor any person acting on behalf of the Company has offered or sold any of the Shares by any form of general solicitation or general advertising.

3.7 To the best of the Company’s knowledge, the Company owns, or has the right to use, all patents, trademarks, service marks, trade names, copyrights, licenses, trade secrets or other proprietary rights necessary to its business as now conducted without conflicting with or infringing upon the right or claimed right of any person under or with respect to any of the foregoing. The Company has not received any communications alleging that the Company has violated the patents, trademarks, service marks, trade names, copyrights or trade secrets or other proprietary rights of any other person or entity. The Company is not aware of any violation by a third party of any of the Company’s patents, trademarks, service marks, trade names, copyrights, trade secrets or other proprietary rights.

3.8 Except as disclosed in the SEC Reports filed on or prior to the execution date of this Agreement: (i) the Company has not incurred any material liabilities or obligations, indirect, or contingent, or entered into any material oral or written agreement or other transaction which is not in the ordinary course of business or which could reasonably be expected to result in a material reduction in the future earnings or prospects of the Company; (ii) except as described in the SEC filings made prior to the execution date of this Agreement, the Company has not paid or declared any dividends or other distributions with respect to its capital stock and the Company is not in default in the payment of principal or interest on any outstanding debt obligations; (iii) there has not been any change in the capital stock of the Company other than the sale of the Shares, shares or options issued pursuant to stock option plans or purchase

plans approved by the Company’s Board of Directors; and (iv) there has not been any other event or change that would have, individually or in the aggregate, a Material Adverse Effect.

3.9 The financial statements of the Company and the related notes contained in the SEC filings made by the Company prior to the execution date of this Agreement present fairly, in accordance with generally accepted accounting principles, the financial position of the Company as of the dates indicated, and the results of its operations, cash flows and the changes in shareholders’ equity for the periods therein specified, subject, in the case of unaudited financial statements for interim periods, to normal year-end audit adjustments. Such consolidated financial statements (including the related notes) have been prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout the periods therein specified, except that unaudited financial statements may not contain all footnotes required by generally accepted accounting principles. The Company has to the extent required complied in all material respects with the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002.

4 CONDITIONS TO OBLIGATIONS OF EACH PARTY.

4.1 The Company’s obligation to complete the sale and issuance of the Shares to the Subscriber at the Closing is subject to the fulfillment on or prior to the Closing of the following conditions, which conditions may be waived at the option of the Company to the extent permitted by law:

(a) The representations and warranties made by the Subscriber in Article 2 hereof shall be true and correct when made, and shall be true and correct on and as of the Closing Date.

(b) All covenants, agreements and conditions contained in this Agreement to be performed by the Subscriber on or prior to such sale and issuance shall have been performed or complied with in all material respects.

(c) There shall not then be in effect any legal or other order enjoining or restraining the transactions contemplated by this Agreement.

(d) There shall not be in effect any law, rule or regulation prohibiting or restricting the issuance and sale of the Shares or requiring any consent or approval of any person which shall not have been obtained to issue or sell the Shares, or in either case to otherwise consummate the transactions contemplated hereby (except as otherwise provided in this Agreement).

(e) The Company shall have received the License executed by the Subscriber.

4.2 The Subscriber’s obligation to purchase the Shares at the Closing is subject to the fulfillment on or prior to the Closing of the following conditions, which conditions may be waived at the option of the Subscriber to the extent permitted by law:

(a) The representations and warranties made by the Company in Article 3 hereof shall be true and correct when made, and shall be true and correct on and as of the Closing Date (except for any representation or warranty that speaks as of a specific date, which shall be true and correct as of such date).

(b) All covenants, agreements and conditions contained in this Agreement to be performed by the Company on or prior to such purchase shall have been performed or complied with in all material respects.

(c) There shall not then be in effect any legal or other order enjoining or restraining the transactions contemplated by this Agreement.

5 COVENANTS OF COMPANY

5.1 The Company agrees to use commercially reasonable efforts:

(a) to make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act;

(b) to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”); and

(c) to furnish to the Subscriber upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144, and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as the Subscriber may reasonably request to avail itself of any similar rule or regulation of the SEC allowing it to sell any such securities without registration.

5.2 At any time commencing on June 1, 2006, if the Company shall determine to proceed with the actual preparation and filing of a registration statement under the Securities Act in connection with the proposed offer and sale of any of its securities by it or any of its security holders (other than a registration statement on Form ▇-▇, ▇-▇ or other limited purpose form), then the Company will give written notice of its determination to Subscriber. Upon the written request from Subscriber, within twenty (20) days after receipt of any such notice from the Company, the Company will, except as herein provided, cause all of the Shares (the “Registrable Securities”) to be included in such registration statement, all to the extent requisite to permit the sale or other disposition by the Subscriber; provided, further, that nothing herein shall prevent the

Company from, at any time, abandoning or delaying any registration. If any registration pursuant to this Section 5.2 shall be underwritten in whole or in part, the Company may require that the Registrable Securities requested for inclusion to be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. The right of the Subscriber to have shares registered pursuant to this Section 5.2 shall cease at such time as the Shares are freely saleable without the volume limitations of Rule 144.

6 MISCELLANEOUS.

6.1 This Agreement shall not be changed, modified or amended except by a writing signed by the parties to be charged, and this Agreement may not be discharged except by performance in accordance with its terms or by a writing signed by the party to be charged.

6.2 This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of North Carolina, excluding that body of law known as choice of law, and shall be binding upon the parties hereto in the United States and worldwide. All disputes with respect to this Agreement shall be brought and heard either in the North Carolina state courts located in Mecklenburg County, North Carolina, or the federal district court for the Eastern District of North Carolina located in Raleigh, North Carolina. The parties to this Agreement each consent to the in personam jurisdiction and venue of such courts. The parties agree that service of process upon them in any such action may be made if delivered in person, by courier service, by telegram, by facsimile or by first class mail, and shall be deemed effectively given upon receipt.

6.3 The holding of any provision of this Agreement to be invalid or unenforceable by a court of competent jurisdiction shall not affect any other provision of this Agreement, which shall remain in full force and effect. If any provision of this Agreement shall be declared by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced in whole or in part, such provision shall be interpreted so as to remain enforceable to the maximum extent permissible consistent with applicable law and the remaining conditions and provisions or portions thereof shall nevertheless remain in full force and effect and enforceable to the extent they are valid, legal and enforceable, and no provisions shall be deemed dependent upon any other covenant or provision unless so expressed herein.

6.4 It is agreed that a waiver by either party of a breach of any provision of this Agreement shall not operate, or be construed, as a waiver of any subsequent breach by that same party.

6.5 The parties agree to execute and deliver all such further documents, agreements and instruments and take such other and further action as may be necessary or appropriate to carry out the purposes and intent of this Agreement.

6.6 This Agreement may be executed in two or more counterparts each of which shall be deemed an original, but all of which shall together constitute one and the same instrument.

6.7 The Subscriber represents and warrants that it has neither engaged, consented to nor authorized any broker, finder or intermediary to act on its behalf, directly or indirectly, as a broker, finder or intermediary in connection with the transactions contemplated by this Agreement. The Subscriber hereby agrees to indemnify and hold harmless the Company from and against all fees, commissions or other payments owing to any such person acting on behalf of the Subscriber hereunder.

6.8 Any covenant, agreement, representation or warranty made by the Company and the Subscriber herein that by its terms provides that it shall be performed, in whole or in part, after the Closing Date, including, without limitation, Articles 5.1 and 5.2, shall survive the execution of this Agreement and the delivery to the Subscriber of the Shares.

In witness whereof, each of the parties has caused this Subscription Agreement to be signed by its duly authorized representative.

Eighteen (18) months prior to the beginning of the calendar quarter which contains the expected date of the First Commercial Sale in the Territory, the Parties shall discuss in good faith the projected quantity requirements of the Compound for the first three (3) years following the First Commercial Sale in the Territory.

3.1.2

Rolling Forecast

Twelve (12) months prior to the beginning of the calendar quarter which contains the expected date of the First Commercial Sale in the Territory, Chelsea shall provide DSP with a good faith forecast of quantity requirements of the Compound for three (3) years following the First Commercial Sale in the Territory, including the quarterly quantities of the Compound for the first year and the yearly quantities of the Compound for the subsequent two (2) years. Chelsea shall update such forecast for the three (3)-year period on a rolling basis by the end of every calendar quarter thereafter during the term of this Agreement.

3.2	Firm Order

The first quarter of the rolling forecast placed by Chelsea pursuant to Section 3.1.2 above shall be deemed as a firm order. Chelsea shall designate a delivery date within the applicable calendar quarter at the time the forecast becomes a firm order. The quantity of the Compound in the firm order shall not be less than [*] percent ([*]%) nor more than [*] percent ([*]%) of the quantity specified in the latest forecast for the same quarter. In case the quantity in the firm order exceeds [*] percent ([*]%) of that in the latest forecast, DSP’s failure to supply the quantities exceeding [*] percent ([*]%) of that in the latest forecast shall not constitute a breach of this Agreement.

3.3	Postponement

Prior to receiving Marketing Authorization Approval in any country of the Territory, Chelsea may change the expected date of First Commercial Sale, at no cost to Chelsea, by notifying DSP in writing. Thereafter but prior to receiving Marketing Authorization Approval, Chelsea may postpone the expected date of First Commercial Sale one or more additional times (each, a “Postponement”) upon written notice to DSP. In the event of a Postponement, other than due to a delay by DSP, Chelsea shall be responsible for the costs of the Compound ordered under any Firm Order (whether such orders have been delivered by DSP or not) subject to the conditions set forth in Sections 4 and 5, and Chelsea and its sublicensees shall have no other responsibility to DSP as a result of such Postponement. DSP agrees that, provided that Chelsea is using Commercially Reasonable Efforts to achieve the First Commercial Sale, there shall be no limit on the number of Postponements or the duration of any Postponement, to the extent reasonable, that may be made by Chelsea prior to receiving Marketing Authorization Approval in any country of the Territory.

3.4	Minimum Order Quantity

The minimum order quantity (lot) per shipment shall be [*] kilograms ([*]kg) of the Compound.

3.5	Allocation in Case of Shortage

In the event that the Compound is, or is anticipated by DSP to be, in short supply, DSP shall notify Chelsea in writing of such circumstances as soon as possible, including the underlying reasons for such shortage.

Under the foregoing circumstances, DSP shall allocate to Chelsea an amount of the Compound proportionate to the quantity of Chelsea’s rolling forecast for the twelve (12)-month period immediately preceding such shortage divided by the total forecasted demand for the Compound of DSP and all of DSP’s customers (including Chelsea) for the same period, provided that DSP shall reserve the right to adjust the foregoing allocation scheme, taking into account any prevailing ethical considerations and the relative strategic and financial significance of the markets involved.

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

3.6	Minimum Purchase Requirement

Chelsea recognizes that DSP will need some initial investment to satisfy estimated Chelsea’s requirements for the Compound and therefore, Chelsea agrees to purchase at least [*] kilograms ([*]kg) of the Compound from DSP hereunder during the Supply Term after any Marketing Authorization Approval is obtained, taking such DSP’s investment into due consideration.

DELIVERY

4.1	Delivery Terms

All of the Compound shall be delivered to Chelsea or such other co-signee as may be designated by Chelsea FCA (as defined by INCOTERMS 2000 as amended) at Kansai International Airport, Osaka, Japan.

Any reasonable and documented costs and expenses unanimously agreed to by the Joint Committee, solely to meet and to satisfy the requirements of any laws, rules and regulations in the Territory, including cGMPs of the USA, shall be reimbursed to DSP by Chelsea according to the method of payment as determined by the Joint Committee, provided that in case that the Joint Committee does not approve the investment for the purpose of this Section 5.1 proposed by DSP and/or Chelsea, DSP shall have no obligation to invest in and implement such requirements and shall have no liability for non-implementation of such requirements.

5.2	Change Control

In the event that DSP intends any change in the Specifications, the location of the manufacture, the manufacturing process, or the raw materials, which requires approval of the Regulatory Authority, DSP shall first give a prior written notice to Chelsea and then obtain an approval from the Regulatory Authority, provided that prior to implementation of such change that requires Chelsea to pay the cost for, all such proposed changes, including amount and method of payment by

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

Chelsea, shall be unanimously approved by the Joint Committee and then, all such proposed changes shall be approved by the applicable Regulatory Authority. In case that the Joint Committee does not approve such proposed changes, DSP shall have no obligation to invest in and implement such proposed changes and shall have no liability for non-implementation of such proposed changes.

5.3

Release

DSP shall perform quality assurance test of all the batches of the Compound manufactured by DSP in accordance with the methods of analysis and the Specifications approved by the FDA and shall release only the Compound from the batches which passed such quality assurance test. DSP shall furnish Chelsea with signed original certificates of quality assurance test for each batch of the Compound (the “Certificate of Analysis”). Such Certificate of Analysis shall certify with respect to each shipment and batch (identified by batch number) (i) the quantity of the shipment, and (ii) that the Compound delivered meets the Specifications, as well as any further information required by the relevant Regulatory Authority that Chelsea may have previously notified DSP is necessary. Chelsea or the Sublicensee shall be under no obligation to accept any shipment of Compound which does not accompany Certificate of Analysis.

5.4	Acceptance

Promptly after receipt of the Compound, Chelsea shall perform confirmatory quality assurance test of all the batches of the Compound in accordance with the Specifications by itself or its designee and notify DSP in writing within forty (40) days after receipt at Chelsea’s facilities or such other destination as may be designated by Chelsea of each shipment of the Compound if the confirmatory quality assurance test indicates that the delivered Compound does not meet the Specifications. On Chelsea’s failure to notify DSP of the non-conformance to the Specifications within such forty (40)-day period, Chelsea shall be deemed to have accepted the delivered Compound.

Upon receipt by DSP of the notice of non-conformance from Chelsea, each Party shall re-test the Compound which Chelsea alleges does not conform to the Specifications. In the event that the Parties reach an agreement on the non-conformance to the Specifications as a result of the above re-test, DSP shall replace such Compound and the cost of the replacement reasonably incurred by the Parties shall be borne by DSP.

If the results of the re-test performed by each Party are inconsistent, the Parties shall have the Compound tested by a reputable Third Party testing organization selected by mutual agreement of the Parties and cooperate in the furnishing of necessary analytical methodology, subject to appropriate safeguards of confidentiality, to such testing organization. The decision of such Third Party testing organization shall be binding upon both Parties and the Party whose test results are inconsistent with those of the Third Party testing organization shall bear the costs of having such Third Party test the Compound. In addition, if the

decision of the Third Party testing organization shows that the Compound does not meet the Specifications, DSP shall replace such Compound with no charge to Chelsea. The non-conforming Compound shall be returned to DSP or destroyed by Chelsea or its designee at the expense of DSP in accordance with DSP’s instructions.

5.5	Inspection by Chelsea

Chelsea may inspect facilities of DSP or DSP’s Affiliate during normal business hours of the facilities upon a reasonable prior written notice and DSP shall accept or shall have its Affiliate accept such inspection to the extent such facilities relate to the manufacture of the Compound.

DSP shall use Commercially Reasonable Efforts to have the Third Parties, who are entrusted or contracted all or a part of manufacturing process of the Compound, if any, accept the foregoing inspections by Chelsea.

5.6	Inspection by Regulatory Authority

DSP shall accept, have its Affiliate accept, and seek to have the Third Parties, who are entrusted or contracted all or a part of manufacturing process of the Compound, if any, accept, the inspection by the Regulatory Authority if it is required for Chelsea to maintain the Marketing Authorization Approval. Chelsea shall use Commercially Reasonable Efforts to obtain the information on such inspection in advance and forward it to DSP. DSP shall permit Chelsea or Chelsea’s Affiliates to be present at any inspection by the Regulatory Authority. If any issue on the manufacturing of the Compound is raised in the inspection by the Japanese, US and EU Regulatory Authorities, DSP shall inform Chelsea of the issue.

5.7	Retention of Samples and Records

DSP shall retain samples from each lot of the Compound manufactured for Chelsea in quantities sufficient for complete analysis and shall retain manufacturing batch records of each lot of the Compound. DSP shall retain such samples and records until the first (1st) anniversary of the expiration of the shelf life of each lot or such longer period of time that Chelsea notifies DSP in writing is required by applicable laws, rules or regulations. Chelsea shall also notify DSP of any additional records that are required to be retained for such period of time.

12.1	Relationship of the Parties

For all purposes, Chelsea’s legal relationship under this Agreement to DSP shall be that of independent contractor. This Agreement is not a partnership agreement and nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

12.2	Force Majeure

The occurrence of an event which materially interferes with the ability of a Party to perform its obligations or duties hereunder, which is not within the reasonable control of the Party affected (including any of its Affiliates and Sublicensees), and which could not with the exercise of due diligence have been avoided (“Force Majeure Event”), including but not limited to, fire, accident, strike, riot, civil commotion, act of God, inability to obtain raw materials, delay or errors by shipping companies or change in law, shall not excuse such Party from the performance of its obligations or duties under this Agreement, but shall merely suspend such performance during the Force Majeure Event. The Party subject to a Force Majeure Event shall promptly notify the other Party in writing of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to time, with its best estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so

affected shall use Commercially Reasonable Efforts to avoid or remove such causes of non-performance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty shall promptly recommence. The Party subject to the Force Majeure Event shall not be liable to the other Party for any direct, indirect, consequential, incidental, special, punitive, exemplary or other damages arising out of or relating to the suspension or termination of any of its obligations or duties under this Agreement by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 12.2.

12.3	Governing Law and Arbitration

This Agreement shall be governed by and construed and enforced in accordance with the laws of England, excluding that body of law known as choice of law, and shall be binding upon the Parties in the United States and worldwide.

The arbitration shall be held in Osaka, Japan if the arbitration is initiated by Chelsea and in Charlotte, North Carolina, USA if the arbitration is initiated by DSP.

In any event, the assigning Party shall provide the other Party with ten (10) business days’ prior written notice of assignment. Any assignment in violation of this provision is void and without effect.
