MANUFACTURE, PURCHASE AND SUPPLY OF API

2.1 Supply. Pursuant to the terms and conditions of this Agreement, during the Term, Solvay agrees to supply or have supplied Jazz Pharmaceuticals’ requirements of API (including any API to be used for manufacturing clinical trial supplies). Subject to the provisions of Section 2.7, Jazz Pharmaceuticals agrees to purchase from Solvay, or its permitted designee, during the Term, certain quantities of API ordered pursuant to this Agreement. API supplied hereunder shall be supplied as Bulk API and shall meet the API Specifications. Each shipment shall be accompanied by a Certificate of Analysis in English. API shall be manufactured in accordance with cGMP and all other applicable Laws and any procedures set forth in the API Specifications, and such additional procedures as may be agreed upon by the parties. Notwithstanding the requirements for the purchase and delivery of API set forth in this Article 2, Solvay agrees to sell, and Jazz Pharmaceuticals agrees to purchase, up to 4,000 kilograms of API for $453 per kilogram and on the payment terms set forth in Section 3.3 of this Agreement.

2.2 Firm Orders.

(a) From time to time and subject to the other provisions of this Agreement, Jazz Pharmaceuticals shall place its firm orders for API, specifying requested delivery dates. The delivery dates specified in any such orders shall not be less than ninety (90) days from the date of such orders.

(b) To the extent that firm orders requested for shipment in any quarter exceed the most recent Jazz Pharmaceuticals forecast for such quarter provided under Section 2.4 by more than twenty-five percent (25%) (any excess of twenty-five percent (25%) or less shall, for this purpose, be deemed not to exceed forecast), Solvay shall use its commercially reasonable efforts to accommodate any such excess contained in Jazz Pharmaceuticals’ firm orders, but Solvay shall not be liable to Jazz Pharmaceuticals for any inability, despite its reasonable efforts, to fill orders in excess of such forecast.

3

(c) Solvay shall use commercially reasonable efforts to accommodate any Jazz Pharmaceuticals’ request for the API in excess of the quantities described in any previously-submitted purchase order, or for delivery of the API sooner than as otherwise provided in such purchase order. Should Jazz Pharmaceuticals business conditions necessitate reduction or delay in purchase order requirements, then Solvay shall use commercially reasonable efforts to implement such requested changes; provided that Jazz Pharmaceuticals shall bear any and all additional costs or expenses related to the manufacturing of the API as a result of Solvay’s compliance with such request. Notwithstanding the foregoing, Solvay shall not take any action in response to any such requests which would result in charges to Jazz Pharmaceuticals in addition to those set forth in the respective purchase order without Jazz Pharmaceuticals’ prior written consent.

2.3 Acceptance. Orders placed with Solvay by Jazz Pharmaceuticals pursuant to the provisions of Section 2.2 shall be acknowledged by Solvay in writing. Solvay shall use commercially reasonable efforts to ensure that the API ordered by Jazz Pharmaceuticals in accordance with this Agreement is shipped in accordance with the delivery dates specified in Jazz Pharmaceuticals’ purchase order accepted by Solvay, and Solvay shall notify Jazz Pharmaceuticals promptly of any significant anticipated delay.

2.4 Forecasts and Production Planning.

(a) On or before the fifth (5^th) working day of each month, Jazz Pharmaceuticals shall provide Solvay with an eighteen (18) month rolling forecast of the quantity of API required by Jazz Pharmaceuticals, by month, for the following eighteen (18) months (each, a “Forecast”). It is understood that such Forecasts, after the third (3^rd) month, are intended to be good faith estimates only, and shall not be binding upon Jazz Pharmaceuticals. Solvay’s inability to supply amounts in excess of the foregoing amounts shall not constitute a breach of this Agreement by Solvay.

(b) Solvay shall base its production planning on the forecasts provided to Solvay by Jazz Pharmaceuticals pursuant to Section 2.4(a). Solvay shall have the right, at any time, to order materials and supplies to manufacture one hundred percent (100%) of those amounts of API ordered by Jazz Pharmaceuticals under Section 2.2 and forecast by Jazz Pharmaceuticals under Section 2.4(a) for the then current and next two calendar quarters. In addition, to the extent any materials necessary to the manufacture of the API require a longer lead time, Solvay shall be entitled to order such materials as it deems appropriate to fulfill its obligations hereunder and consistent with normal production practices in the pharmaceutical industry, and considering the term of this Agreement. If any such materials or any work in process become unusable due to a change in the API Specifications or orders lower than forecasts, Solvay shall have the right to invoice Jazz Pharmaceuticals for the full cost of unusable materials or work in process and Jazz Pharmaceuticals shall promptly pay such invoice. Jazz Pharmaceuticals shall have full rights and title to such obsolete materials (and work in process). At Jazz Pharmaceuticals’ election, such materials (and work in process) shall be (i) destroyed by Solvay or (ii) transferred by Solvay to Jazz Pharmaceuticals.

4

(c) Notwithstanding the foregoing, Solvay agrees to use its commercially reasonable efforts to cooperate with Jazz Pharmaceuticals in connection with Jazz Pharmaceuticals’ commercial launch of any pharmaceutical product containing the API. Such cooperation shall include, but not be limited to, joint review and revision of forecasts and firm orders during the period prior to FDA approval and during the twelve (12) months immediately following the commercial launch of such pharmaceutical product in the United States (and covering similar periods for other applicable countries). Solvay shall use its commercially reasonable best efforts to accommodate any changes requested by Jazz Pharmaceuticals during such period, but Solvay shall not be liable to Jazz Pharmaceuticals for any inability to accommodate such changes provided it has used its commercially reasonable efforts to respond to such changes.

2.5 Delivery. Shipments of API shall be made ex-works (“EXW”) (as such term is defined in INCOTERMS 2000) Solvay’s manufacturing facility unless otherwise mutually agreed to in writing by the parties. Risk of loss or of damage to the API shall remain with Solvay until such API is loaded onto the carrier’s vehicle by Solvay for shipment at the shipping point at which time risk of loss or damage shall transfer to Jazz Pharmaceuticals. Solvay shall, in accordance with Jazz Pharmaceuticals’ instructions and as agent for Jazz Pharmaceuticals, (i) arrange for shipping to be paid by Jazz Pharmaceuticals and (ii) at the Jazz Pharmaceuticals’ risk and expense, obtain any export licence or other official documentation necessary to export the API from the United States. Jazz Pharmaceuticals shall arrange for insurance and shall select the freight carrier used by Solvay to ship the API and may monitor Solvay’s shipping and freight practices as they pertain to this Agreement. API shall be transported in accordance with the API Specifications and other applicable Laws.

2.6 Manufacturing Changes.

(a) For changes to the API Specifications or manufacturing processes that are required by applicable Laws (collectively “Required Manufacturing Changes”), Solvay and Jazz Pharmaceuticals shall cooperate in making such changes and use commercially reasonable efforts to implement such changes promptly in a manner that minimizes any effect on the supply hereunder to Jazz Pharmaceuticals of API meeting the API Specifications.

(b) For changes to the API Specifications or manufacturing process that are not Required Manufacturing Changes (collectively “Discretionary Manufacturing Changes”), Solvay and Jazz Pharmaceuticals must each have agreed to any Discretionary Manufacturing Changes for them to be made and once agreed, each party shall, to the extent commercially reasonable under the circumstances, cooperate in making such changes, and each agrees that it shall not unreasonably withhold its consent to such Discretionary Manufacturing Changes.

(c) Notwithstanding the foregoing, all external costs, including, without limitation, obsolete raw materials, regulatory filings, work-in-process, equipment and API (i) associated with Required Manufacturing Changes that are caused by, or result from, the acts or omissions of a single party shall be borne by such party, (ii) associated with all Required Manufacturing Changes for use of the API in the United States shall be borne by Jazz Pharmaceuticals, (iii) associated with all Required Manufacturing Changes for use of the API in any country other than the United States shall be borne by Solvay and (iv) all costs associated with Discretionary Manufacturing Changes shall be borne by the party requesting such changes.

2.7 Shortages.

(a) During the Term of this Agreement, if Solvay is not able to meet firm orders submitted by Jazz Pharmaceuticals pursuant to Section 2.2 due to a shortage of API, Solvay shall promptly notify Jazz Pharmaceuticals of such shortage of such API, and, if possible, the date such shortage of API is expected to end. In such event, Solvay shall allocate its available supply of such API to Jazz Pharmaceuticals in such proportion as the quantity of such API supplied to Jazz Pharmaceuticals over the immediately preceding twelve (12)-month period bears to the total quantity of API supplied by Solvay to all parties over the preceding twelve (12)-month period. In addition, if Solvay is not able to supply any API, at such point in time when Solvay resumes supply of the API, Jazz Pharmaceuticals shall receive the first Batch of API available for commercial supply.

(b) In the event an interruption described in Section 2.7(a) continues for more than one hundred eighty (180) days, then upon Jazz Pharmaceuticals’ written request, Solvay will provide all necessary information, licenses and technical assistance required to reasonably assist Jazz Pharmaceuticals in (i) the qualification of an alternate API manufacturer and (ii) obtaining all authorizations of the appropriate authorities for the approval of the alternate manufacturer of API for the Territory. Notwithstanding the foregoing, Solvay shall not incur any out of pocket costs as a result of providing this assistance, and Solvay shall only be responsible for assuming its own internal expenses incurred as a result of providing this assistance.

ARTICLE 4

QUALITY AND REGULATORY MATTERS

4.1 Quality Control. Solvay shall produce API in accordance with the API Specifications, cGMP, the Laws and any procedures agreed upon by the parties in writing, and shall permit quality assurance representatives of Jazz Pharmaceuticals or its designee to audit and inspect Solvay’s manufacturing facilities and testing procedures for API and the related batch records, upon thirty (30) days written notice, twice in each calendar year (and additional times, if deficiencies are noted, to monitor correction thereof), during normal business hours and on a confidential basis. If deficiencies are found during any audits or inspections, the parties shall meet promptly to discuss and resolve them, and Jazz Pharmaceuticals or its designee shall be entitled to make reasonable follow-up inspections to monitor the correction of the deficiencies. Solvay shall use commercially reasonable efforts to obtain the right for Jazz Pharmaceuticals or its designee to have similar inspection, audit and follow-up rights with respect to all third-party suppliers used by Solvay to provide key materials for API. Solvay agrees to allow the FDA or any other applicable regulatory authority to inspect its facilities and all records required under cGMP and all other applicable regulations in connection with such production. Solvay shall furnish to Jazz Pharmaceuticals all material information supplied to, or supplied by, such regulatory authority or third party supplier to the extent that such report relates to API, or the ability of Solvay to supply such API, within five (5) business days of their receipt of such information or delivery of such information, as the case may be.

4.2 Testing.

(a) Solvay agrees to permit Jazz Pharmaceuticals or its designee to review Solvay’s standard operating procedures for the manufacture of the API. Solvay shall test or cause to be tested each Batch of API to be supplied pursuant to this Agreement, in accordance

7

with the approved testing methods, before delivery of such API to Jazz Pharmaceuticals or its designee. Each time Solvay ships API to Jazz Pharmaceuticals or its designee, it shall provide Jazz Pharmaceuticals or its designee with the Certificate of Analysis that sets out the test results for each Batch of API and that certifies that such Batch of the API complies with the API Specifications and was manufactured in accordance with cGMP. Solvay shall retain a sample of each Batch of API shipped for at least the shelf life of such Batch plus one (1) year, or such longer period as may be required by cGMP. Nothing contained herein, however, shall be deemed or construed to require Solvay to turn over the DMF relative to the API.

(b) Solvay shall conduct stability testing on the API in accordance with the Quality Agreement and API Specifications. Solvay shall not make any changes to the API Specifications or testing protocols without prior written approval from Jazz Pharmaceuticals. Solvay shall promptly provide any and all data and results relating to the stability testing of the API upon request by Jazz Pharmaceuticals. In the event that any Batch of the API fails, or is suspected to fail, stability testing, Solvay shall notify Jazz Pharmaceuticals within two (2) business days and Solvay and Jazz Pharmaceuticals shall jointly determine the proceedings and methods to be undertaken to investigate the causes of such failure.

4.3 Notice of Failure to Meet API Specifications. Upon Solvay’s discovery that any Batch of API fails to conform to the API Specifications, Solvay shall notify Jazz Pharmaceuticals within two (2) business days of discovery of such failure to meet the API Specifications and of the nature thereof. Solvay shall investigate all such failures and promptly and cooperate with Jazz Pharmaceuticals in determining the cause for the failure and a corrective action to prevent future failures.

4.4 Records. Solvay shall keep records of the manufacture, testing and shipping of the API, and retain samples of such API as are necessary to comply with the API Specifications and all manufacturing regulatory requirements and Laws applicable to Solvay, as well as to assist with resolving API complaints and other similar investigations. Copies of such records and samples shall be retained for a period of one (1) year following the date of API expiry or longer if required by Law, after which Solvay may destroy such records or samples; provided, however, Solvay shall notify Jazz Pharmaceuticals in writing at least thirty (30) days prior to such destruction and shall retain or deliver such records or samples to Jazz Pharmaceuticals, at Jazz Pharmaceuticals’ option and expense, if Jazz Pharmaceuticals so requests.

4.5 Notice; Replacement. Jazz Pharmaceuticals or its designee shall notify Solvay in writing of (i) any claim relating to any API that fails to meet the API Specifications or (ii) any shortage in quantity of any shipment of API as soon as reasonably practical, but not later than forty-five (45) days of receipt of such API except where such failure to meet the API Specifications could not be reasonably known at such time, in which case such forty-five (45) day period commences when Jazz Pharmaceuticals could reasonably have known of such failure. Jazz Pharmaceuticals or its designee shall be deemed to have accepted the API if it does not provide Solvay written notice of such shortfall or failure to meet specification within such forty-five (45) day period. If the parties agree that such API is defective or that there is a shortage, Solvay shall replace the defective API or use its commercially reasonable best efforts to make up the shortage at the next practical delivery date, at no additional cost to Jazz Pharmaceuticals. Jazz Pharmaceuticals shall make arrangements with Solvay for the return or disposal of any rejected API; the costs of such return or disposal shall be paid by Solvay. In the event that only a limited supply of API is available to replace or supply such rejection or shortage, then Solvay

8

shall ship to Jazz Pharmaceuticals such amount of API as is available and Jazz Pharmaceuticals shall be promptly reimbursed or credited against future orders, at Solvay’s option, for amounts paid for the remaining quantity of rejected API.

4.6 Disputes. If, for any reason (i) Jazz Pharmaceuticals disagrees with Solvay’s certification that any API meets the API Specifications or that any API was manufactured in accordance with cGMP or both, or (ii) Jazz Pharmaceuticals rejects any shipment in accordance with Section 4.5 and Solvay disagrees, the relevant party shall assert any such disagreement or rejection in writing, setting forth the specifics of its disagreement or rejection within forty-five (45) days after Solvay’s certification with respect to the API in question. The parties shall attempt in good faith, within the forty-five (45) day period following the other party’s receipt of such written notice, to resolve the dispute. If the parties fail to agree during such time period, they shall retest jointly, in a laboratory agreed upon by the parties, in each case using the test methodology set forth in the API Specifications. If the joint tests substantiate Jazz Pharmaceuticals’ disagreement or rejection, the API in question shall, at Solvay’s election and cost, be destroyed or be returned to Solvay. Jazz Pharmaceuticals shall not be obligated to pay for justifiably rejected API and Solvay or Jazz Pharmaceuticals shall notify, if required by Law, the relevant government agencies regarding any affected API. If the joint test does not substantiate Jazz Pharmaceuticals’ claim, Jazz Pharmaceuticals shall accept the API in question and pay the purchase price with respect to such API. The results of the joint testing shall be binding on the parties, and the costs of the joint testing shall be borne by the party whose results were not substantiated by the joint testing.

4.7 Recalls. In the event (i) the FDA or any other regulatory authority issues a request, directive or order that a product containing the API manufactured by Solvay pursuant to this Agreement be recalled, (ii) a court of competent jurisdiction orders such a recall, or (iii) Jazz Pharmaceuticals shall reasonably determine that the a product containing the API manufactured by Solvay pursuant to this Agreement should be recalled, all costs of such API recall shall be borne by Jazz Pharmaceuticals, except to the extent that any recall results from the breach by Solvay of its warranties under Article 5, which costs shall be governed by the provisions of Section 6.1.

4.8 Technical Complaints. Jazz Pharmaceuticals shall promptly submit to Solvay all API quality or manufacturing inquiries and technical API quality complaints, together with all available evidence and other information relating thereto, in accordance with procedures to be agreed upon by the parties. Except as otherwise required by Law, Solvay shall be responsible for investigating all such technical inquiries and complaints regarding the API and the outcome of such investigation shall be promptly reported by Solvay to Jazz Pharmaceuticals in writing. Where complaints or matters result from acts or omissions of Solvay, investigation and correction shall be at Solvay’s expense; otherwise investigation and correction shall be at Jazz Pharmaceuticals’ expense.

4.9 Response to Complaints and/or Adverse Drug Events. In the event of a reported complaint and/or adverse drug event, if the nature of the reported complaint and/or adverse drug event requires testing, Solvay shall, at Jazz Pharmaceuticals’ reasonable request and expense (unless the event was the result of Solvay’s failure to manufacture API in accordance with the terms hereof, in which case the reasonable costs of such testing shall be borne by Solvay), investigate and perform all requested testing including without limitation, analytical testing of corresponding retention samples, and provide the results thereto to Jazz Pharmaceuticals as soon as reasonably practicable. Such testing shall be performed using the approved testing procedures as set forth in the API Specifications.

9

4.10 Reports. For so long as Solvay is manufacturing and/or supplying API pursuant to this Agreement, Solvay shall furnish to Jazz Pharmaceuticals manufacturing reports reasonably requested by Jazz Pharmaceuticals, but in no event more than quarterly, including such information that is agreed upon by the parties.

CONFIDENTIALITY

8.1 Nondisclosure. During the Term of this Agreement and for a period of ten (10) years after expiration or termination of this Agreement, the parties, their Affiliates and their respective employees, directors, officers, consultants and contractors shall keep and maintain as confidential any Confidential Information (as defined below) supplied by the other party during the Term of this Agreement. For purposes of this Agreement, “Confidential Information” means all information disclosed by a party in connection with this Agreement other than: (i) information that at the time of disclosure by one party to the other is in the public domain or otherwise publicly known; (ii) information which after disclosure by one party to the other becomes part of the public domain, other than by breach of this Agreement by the receiving party; (iii) information which the receiving party can establish by documentary evidence was already in its possession without restriction at the time of receipt; or (iv) information received from a third party without restriction who was lawfully entitled to disclose such information without restriction.

8.2 Permitted Disclosure. Notwithstanding Section 8.1, the party receiving Confidential Information may disclose such Confidential Information to the extent such disclosure is reasonably necessary in the following instances: (i) to governmental or other regulatory agencies in order to file patent applications or prosecute such applications to grant or to gain approval to conduct clinical trials in relation to the API, provided that the disclosure is limited to the extent reasonably necessary to obtain such patents or authorizations and the disclosing party is notified of the proposed disclosure of its Confidential Information and consents to such disclosure, with such consent not to be unreasonably withheld; (ii) as required by this Agreement; (iii) to Affiliates, employees, consultants, vendors or agents who need to know and agree to be bound by similar terms of confidentiality and non-use at least equivalent in scope to those set forth in this Article 8; or (iv) to the extent that such disclosure has been ordered by a court of law or directed by a governmental authority, provided that, the disclosing party shall give the party that owns the Confidential Information prompt written notice, in advance, to enable it to seek protection or confidential treatment of such Confidential Information.

8.3 Injunctive Relief. The parties hereto understand and agree that remedies at law may be inadequate to protect against any breach of any of the provisions of this Article 8 by either party or their employees, agents, officers or directors or any other person acting in concert with it or on its behalf. Accordingly, each party may be entitled to seek injunctive relief from a court of competent jurisdiction against any action that constitutes any such breach of this Article 8.
