RECITALS

A. Concurrently with this Agreement, Neuromed and Mallinckrodt are entering into that certain Asset Purchase Agreement between Neuromed and Mallinckrodt (the “Purchase Agreement”) pursuant to which Neuromed is selling and assigning to Mallinckrodt, and Mallinckrodt is purchasing from Neuromed, all of Neuromed’s tangible and intangible assets relating to Product (as such term is defined in the Purchase Agreement).

B. In connection with such sale, the Parties desire that Neuromed shall perform, at Mallinckrodt’s cost and expense, certain clinical development and regulatory activities through approval by the FDA of an NDA covering Product, and certain transition services for Mallinckrodt’s benefit in order to facilitate the smooth transition of the Transferred Assets to Mallinckrodt.

The Parties therefore agree as follows:

AGREEMENT

1.9 “Territory” means the United States and its possessions and territories.

2. PRODUCT DEVELOPMENT AND NDA APPROVAL

2.1 Neuromed Development Activities. Notwithstanding that Mallinckrodt has purchased the Transferred Assets pursuant to the Purchase Agreement, the Parties agree that Neuromed shall continue to be involved in Development, through NDA Approval, of Product, under the terms of this Agreement. Neuromed shall conduct any Development efforts in accordance with the Development Plan, using Commercially Reasonable Efforts and at Mallinckrodt’s cost and expense as provided herein. Neuromed will be responsible for using Commercially Reasonable Efforts to conduct the Development of Product through obtaining NDA Approval for Product, including the planning, filing and prosecution of the NDA with the FDA, all in accordance with the Development Plan, subject to Section 2.4 below and review of its Development activities by appropriate Mallinckrodt personnel. Neuromed may utilize

consultants and contractors (such as CROs) to conduct significant portions of the Development activities under this Section 2.1 (and the costs of such third parties shall be included in the Development Costs reimbursed by Mallinckrodt as provided in Section 2.3 below). Neuromed will use its Commercially Reasonable Efforts to conduct all the tasks and meet on a timely basis all the objectives and milestones under the Development Plan. Neuromed will comply (and cause its Affiliates to comply) with all applicable federal, state and local laws and regulations, and will obtain all applicable Governmental Permits, in connection with its performance of the Development work under this Section. The JDC shall oversee Neuromed’s Development efforts, and Neuromed shall keep the JDC fully informed of all development activities taken and results, including all regulatory actions and communications with the FDA relating to the NDA. Neuromed will provide all services in connection with Development with at least the same level of skill, quality, care, timeliness and cost-effectiveness as such services, functions and tasks were performed by Neuromed and/or its Affiliates internally prior to the Closing Date and in a manner that is reasonably calculated to result in approval of the NDA for Product at the earliest possible date and for the indications covered by the Development Plan. Neuromed will perform, and will cause its Affiliates to perform, the Development in a prompt and professional manner, utilizing appropriately qualified and knowledgeable personnel and all tasks will be performed in accordance with industry standards for services of the type performed.

2.2 Joint Development Committee. Promptly after the Effective Date, the Parties shall form a Joint Development Committee (the “JDC”). The JDC shall (a) oversee Neuromed’s Development of the Product under the Development Plan, (b) act as the forum for Mallinckrodt to provide its input into Development and to keep informed about its progress, and (c) offer its advice to expedite or aid the progress of Development work. The JDC shall be comprised of a total of six (6) appropriately qualified members (or such other even number of members as is agreed to in writing by the Parties), with each of Neuromed and Mallinckrodt designating one half of the total number of members as its representatives. Either Party may replace any of its respective JDC representatives with an appropriately qualified representative at any time with reasonable prior written notice to the other Party. The JDC will meet at least once each month so long as Product is being developed by Neuromed under this Agreement, provided that the JDC may agree from time-to-time to meet at a greater or lesser frequency if appropriate under the circumstances. JDC meetings may be conducted by videoconference, teleconference or in person, as requested by a Party, except that at least one of the meetings per year will be conducted in person. The JDC will agree upon the time and location of the meetings. A Neuromed representative of the JDC will act as the chair, and such chair (or a designee) shall coordinate, prepare and circulate an agenda for each JDC meeting reasonably in advance of the meeting. A reasonable number of additional representatives of a Party may attend meetings of the JDC in a non-voting capacity. The JDC shall seek to reach consensus on matters coming before it, but will not have any authority to decide development matters that are Neuromed’s responsibility under this Agreement. Notwithstanding the preceding provisions of this Section 2.2, Mallinckrodt shall have the right to give its prior written approval for those Development activities or actions set forth and described on Appendix C attached hereto, such approval not to be unreasonably withheld.

2.3 Payment of Development Costs. Mallinckrodt shall reimburse Neuromed on a monthly basis for all Development Costs (up to the maximum amount as set forth below) actually incurred by Neuromed in conducting the development of Product under this Agreement through Neuromed obtaining NDA Approval. On a monthly basis and no later than the tenth (10^th) day of each calendar month for so long as this Agreement is in effect with respect to Development, Neuromed shall submit an invoice to Mallinckrodt setting forth the Development Costs incurred in the prior month (accompanied by such detail and supporting documentation as to the percentage of such invoice attributable to work performed in the United States and as to the internal and external costs and expenses, as Mallinckrodt may reasonably request), and Mallinckrodt shall pay each such invoice within thirty (30) days of receipt (provided, that any such amounts paid by Mallinckrodt pursuant to this sentence may be subject to later adjustment pursuant to the audit provisions of Section 5 below). All payments due hereunder will be made in United States dollars and, unless otherwise agreed in writing, will be made by wire transfer to such bank as Neuromed may designate in writing. The maximum amount of reimbursement by Mallinckrodt of Neuromed development costs and expenses under this Section 2.3, combined with any payment by Purchaser for Past Development Costs under and pursuant to the Purchase Agreement, is Sixteen Million Dollars ($16,000,000). At such time as Mallinckrodt has paid such maximum amount of reimbursement to Neuromed, Mallinckrodt shall not be obligated to reimburse Neuromed for any additional Development Costs, and Neuromed shall not be required to continue Development efforts on the Product until such time as Mallinckrodt has given approval for Neuromed’s continued efforts (as contemplated in Section 2.4 below). Neuromed will use good faith, diligent efforts to complete all the tasks covered by the Development Plan within such maximum amount of reimbursement.

2.4 Limitation on Neuromed Development. Neuromed shall not be obligated to conduct Development tasks or efforts beyond those tasks set forth in the Development Plan. If FDA requirements, or other matters, require that development efforts and/or tasks, beyond those set forth in the Development Plan, be undertaken in order to achieve NDA approval for the Product (the “Additional Development Efforts”), then the JDC shall discuss in good faith and seek to agree on whether Neuromed should conduct such required Additional Development Efforts. If the Parties agree that Neuromed shall undertake any specific Additional Development Efforts, Mallinckrodt and Neuromed shall amend the Development Plan to reflect such Additional Development Efforts, and Mallinckrodt shall reimburse Neuromed for all such Additional Development Efforts undertaken under such amended Development Plan (in accordance with the applicable procedures set forth in Section 2.3 and even if the costs of such efforts exceed the limitation in Section 2.3). If the Parties cannot agree on whether Neuromed shall conduct any particular Additional Development Efforts, then Mallinckrodt may, but shall not be required, to conduct any such Additional Development Efforts needed to obtain NDA Approval.

3. TRANSITION SERVICES

3.1 Provision of Transition Services. Neuromed will use Commercially Reasonable Efforts to provide, and as necessary will cause its Affiliates to provide, the Transition Services to Mallinckrodt commencing promptly after the Effective Date, as

reasonably requested by Mallinckrodt or as needed to transition the Business and the Transferred Assets to Mallinckrodt. Except as otherwise expressly provided in this Agreement, Mallinckrodt will reimburse Neuromed for its reasonable internal and out-of-pocket costs and expenses incurred in providing the Transition Services, based on monthly invoices provided by Neuromed. Neuromed will use Commercially Reasonable Efforts to provide the facilities, personnel and other resources required for performance of the Transition Services.

3.2 General Standards of Performance. Neuromed will provide, and will cause its Affiliates to provide, the Transition Services with at least the same level of skill, quality, care, timeliness and cost-effectiveness as such services, functions and tasks were performed by Neuromed and/or its Affiliates internally prior to the Closing Date and in a manner that would be reasonably expected to enable Mallinckrodt to conduct the Business related to the Transferred Assets after the Closing. Neuromed will perform, and will cause its Affiliates to perform, the Transition Services in a timely and professional manner and in accordance with industry standards for services of the type performed. Neuromed will comply, and will cause its Affiliates to comply, with all applicable Laws and will obtain all applicable Governmental Permits in connection with the performance of the Transition Services under this Agreement.

3.3 Skills, Training, and Experience. Neuromed will ensure that Neuromed Personnel performing Transition Services have sufficient skills, training and experience to enable them to perform the Transition Services with the same level of skill, quality, care, timeliness and cost-effectiveness as similar services, functions and tasks are performed for Neuromed.

3.4 Reduction in Services. Mallinckrodt may elect to suspend or not to receive any of the Transition Services at any time, with or without cause, upon written notice to Neuromed. If Mallinckrodt suspends or elects not to receive a Transition Service, Mallinckrodt will pay to Neuromed all amounts due for such discontinued service prior to the effective date of discontinuance.

3.5 Additional Services. If Mallinckrodt reasonably requests that Neuromed perform additional services not included within the scope of the Transition Services described on Appendix B, then the Parties will promptly negotiate in good faith with a view toward adding such additional services to Schedule B on terms and conditions substantially similar to those set forth in this Agreement.

3.6 Service Fees. In consideration for the Transition Services to be performed by Neuromed, Mallinckrodt shall pay Neuromed internal, at the applicable portion FTE Rate based on the actual amount of time any given individual is engaged in the performance of Transition Services, and external costs incurred by Neuromed in performing the Transition Services, as reflected in monthly invoices to Mallinckrodt. Mallinckrodt shall pay each such invoice within thirty (30) days of receipt. All payments due hereunder will be made in United States dollars and, unless otherwise agreed in writing, will be made by wire transfer to such bank as Neuromed may designate in writing.

4. Compensation and Benefits. All Neuromed Personnel performing Development work or providing Transition Services under this Agreement will be deemed to be employees or representatives solely of Neuromed (or its Affiliates) for purposes of all compensation and employee benefits and not to be employees or representatives of Mallinckrodt. Neuromed (or its Affiliates) will be solely responsible for payment of (a) all income, disability, withholding and other employment taxes and (b) all medical benefit premiums, vacation pay, sick pay or other fringe benefits for any employees, agents or contractors of Neuromed who perform any tasks or services hereunder. All Neuromed Personnel will be under the direction, control and supervision of Neuromed, and Neuromed will have the sole right to exercise all authority with respect to the employment, termination, assignment and compensation of such Neuromed Personnel.

5. Audit Rights. Upon at least thirty (30) days prior written notice from Mallinckrodt and not more than twice in each calendar year, Neuromed shall permit, and shall require its Affiliates to permit, an independent certified public accounting firm of nationally recognized standing, selected by Mallinckrodt and reasonably acceptable to Neuromed, to have access during normal business hours and at the audited party’s principal place of business, to such books of account and records of any audited party as may be reasonably necessary to verify the accuracy of the invoices provided by Neuromed under either Section 2.3 or Section 3.6 for any period of time ending not more than twenty four (24) months prior to the date of such request. If an audit pursuant to this Section 5 establishes that Neuromed overcharged Mallinckrodt for Development Costs or fees for Transition Services, then Neuromed shall promptly (and, in any event, no less than ten (10) Business Days after the accounting firm has notified both Neuromed and Mallinckrodt in writing of the nature and amount of any overcharge) remit to Mallinckrodt the amount of such overcharge (to the extent such overcharged amount had been paid by Mallinckrodt to Neuromed) plus interest (at the prime rate plus 2% as published in the Wall Street Journal at the end of the month preceding the month in which such repayment is to be made). The fees charged by such accounting firm in connection with any audit pursuant to this Section 5 shall be paid by Mallinckrodt, provided, however, that such an audit establishes an overcharge by Neuromed that is more than five percent (5%) of the total amounts of Development Costs or Transition Services Fees actually due to Neuromed under this Agreement for the period being audited, then Neuromed shall pay the reasonable fees and expenses charged by such accounting firm in connection with such audit. Mallinckrodt shall treat all financial information subject to review under this Section as the Proprietary Information of Neuromed and its Affiliates, and shall cause its accounting firm to retain all such financial information in confidence. In addition, Mallinckrodt’s accounting firm shall be required to execute a reasonable confidentiality agreement prior to commencing any audit pursuant to this Section 5.

6. Inventions. All inventions, whether or not patentable, including, but not limited to, original works of authorship, developments, designs, improvements, or trade secrets relating to Product and arising from services performed under this Agreement conceived or reduced to practice by Neuromed or its agents or employees (either acting alone or jointly with Mallinckrodt) (the “Mallinckrodt Inventions”) shall be assigned to Mallinckrodt, and Mallinckrodt (or any of its assignees or Affiliates) has the sole and exclusive right to apply for and obtain patent or other protection to use, make, have made, sell, offer for sale, import and

distribute the Mallinckrodt Inventions. If for any reason, at law, equity or otherwise, Mallinckrodt is not deemed to be the assignee of such Mallinckrodt Inventions, then Neuromed hereby assigns all right, title, and interest to such Mallinckrodt Inventions to Mallinckrodt. Neuromed will also promptly disclose to Mallinckrodt all Mallinckrodt Inventions created under this Agreement and will cooperate with and assist Mallinckrodt in seeking protection and protecting the same in the name of Mallinckrodt, including executing any documents Mallinckrodt may reasonably request and obtaining the cooperation of current and former employees and consultants to execute and deliver such documents. If Neuromed utilizes the services of one or more Third Parties in any work or services under this Agreement, Neuromed shall take commercially reasonable measures intending to ensure that all applicable intellectual property relating to Product is assigned by said Third Party to Mallinckrodt.

7. LIMITATIONS OF LIABILITY. IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY LOSS OF PROFIT, INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS AGREEMENT. IN NO EVENT WILL THE AGGREGATE LIABILITY OF EITHER PARTY UNDER THIS AGREEMENT EXCEED THE TOTAL AMOUNT PAID BY MALLINCKRODT TO NEUROMED UNDER THIS AGREEMENT. EACH PARTY ACKNOWLEDGES THAT THE MUTUAL LIMITATIONS OF LIABILITY CONTAINED IN THIS SECTION 7 REFLECT THE ALLOCATION OF RISK SET FORTH IN THIS AGREEMENT AND THAT NEITHER PARTY WOULD ENTER INTO THIS AGREEMENT WITHOUT THESE LIMITATIONS ON LIABILITY.

8. TERM AND TERMINATION
