2. Scope of Work.

2.1 Acceptance of Task Orders; Exhibits. From time to time, the parties may agree that CRO shall perform Services for NovaCardia under one or more Task Orders. The parties shall negotiate each Task Order separately. Each Task Order shall set out with specificity the Services to be performed by CRO in the Study, the Study Protocol to be implemented, the actions to be taken by NovaCardia, the obligations transferred to CRO pursuant to 21 C.F.R. § 312.50 et seq. relating to such Services (only for services provided in the United States), the primary points of contact at each of CRO and NovaCardia with respect to such Study, the time line for the performance of the Services, the estimated costs associated with the Services and the schedule of payments for the performance of the Services. The Task Order for each Study will be attached hereto as a new "Task Order No. " as part of Exhibit A. Any changes or modifications to a Study Protocol or the Task Order shall be in writing and shall also be attached as part of Exhibit A. CRO and NovaCardia shall both sign each mutually accepted Task Order or modification or change thereto. There shall be no minimum or maximum number of Task Orders that the parties may incorporate under this Agreement. To the extent that the terms of any Task Order conflict with, are inconsistent with, or create ambiguities with the terms and conditions of this Agreement, the terms of this Agreement shall govern and control.

2.2 Compliance with Task Orders and Law. CRO agrees to use its best efforts to perform the Services set forth in each Task Order in accordance with the terms and conditions contained in this Agreement, the Study Protocol and in such Task Order. In performing the Services, CRO shall assign personnel who are adequately trained, qualified and experienced to conduct the work as specified in each Task Order. NovaCardia may make reasonable requests for replacement of assigned personnel for cause, and CRO agrees to promptly respond to any such request and to make reasonable efforts to correct the situation. Both parties hereto will perform the obligations set forth herein in conformance with: (a) applicable supranational, national, state and local laws and regulations including, but not limited to (where applicable), the regulations and guidelines of the Federal Food, Drug and Cosmetic Act, as amended, as enforced by the United States Food and Drug Administration and/or the corresponding regulations from the European Medicines Agency (EMEA); and (b) as applicable, accepted standards of good clinical practice. Each Study shall also be conducted in compliance with (a) to the extent conducted in the United States, the Health Insurance Portability and Accountability Act ("HIPAA") of 1996, (b) the International Conference on Harmonization

guidelines, and (c) all requirements imposed by legally constituted IRBs. The parties agree to collect, use and disclose information with respect to any Study subject only in accordance with the informed consents and legal disclosure authorizations obtained from such Study subject as part of the Study, unless otherwise required by law. If government regulatory requirements are changed, then CRO shall comply with the new requirements. If compliance with new regulatory requirements necessitates a change in a Task Order, CRO will obtain NovaCardia's written consent to such change prior to implementation. CRO shall comply strictly with the applicable Study Protocol in performing the Services for a Study.

2.3 Principal Investigators and Participating Institutions. As defined in each Task Order, CRO shall coordinate each Study at clinical sites conducting the Study ("Participating Institutions"). CRO shall enter into an agreement as agent for and on behalf of NovaCardia with each Participating Institution containing terms consistent with those in this Agreement and the applicable Task Order. Each such agreement shall name the investigator at such site with principal responsibility for the Study at such site (the "Principal Investigator"). CRO shall exercise all reasonable efforts to ensure that the data generated by the Participating Institutions shall be coordinated, analyzed and reported in an efficient and effective manner and in a format fully usable by NovaCardia. Prior written approval by NovaCardia of each Principal Investigator (and any replacement thereof) shall be required. In no event shall any Participating Institution be construed to be CRO's subcontractor or agent. NovaCardia shall provide adequate funds to CRO in advance for payments to Participating Institutions in accordance with a payment schedule to be mutually agreed between the CRO and NovaCardia. In no event shall CRO be required to disburse payments to any third parties if sufficient advance funds are not available to cover such disbursements. Any remaining funds will be returned to NovaCardia after termination of each Task Order as soon as all obligations to the Participating Institutions have been satisfied.

2.4 Informed Consent. CRO shall ensure that informed consent documents used for a particular Study include the human subject's express authorization for the disclosure by CRO, the applicable Participating Institution or the Principal Investigator, to NovaCardia, NovaCardia's employees, agents, independent contractors, including without limit CRO, of patient-identifiable information pursuant to HIPAA. The Parties agree to adhere to the principles of medical confidentiality in relation to human subjects involved in the Study and shall comply with the provisions of the Data Protection Directive 95/46/EC and any other applicable date protection legislation with regard to the disclosure of patient- identifiable information, including any relevant 'safe-harbour' requirements regarding export of data outside of the European Union.

2.5 Adverse Experiences. CRO shall promptly, in accordance with applicable laws and regulations, advise NovaCardia of any adverse reactions or side effects occurring during the conduct of any Services that become known to CRO. If any adverse reactions associated with a NovaCardia Product indicate the discovery of significant health hazards, CRO shall notify NovaCardia within 24 hours of making such discovery.

2.6 NovaCardia's Approval of Subcontractors. CRO may not subcontract any of the Services under a Task Order without first obtaining NovaCardia's prior written consent which shall not be unreasonably withheld. CRO will at all times be responsible for the

compliance of its permitted subcontractors with the terms and conditions of this Agreement. CRO reserves the right to use and subcontract with its fully owned affiliates for the provision of services under a Task Order without the prior written consent of NovaCardia.

2.7 Study Data. All data (including, without limitation, case report forms, laboratory work sheets, slides and reports), generated in the course of conducting each Study (collectively, the "Study Data") shall be recorded in a timely, accurate, complete and legible manner in the form as described in each Task Order. NovaCardia shall own all Study Data. During each Study, CRO shall make the Study Data available to NovaCardia representatives for review, verification and copying and shall assist NovaCardia representatives in resolving any discrepancies or errors in the Study Data. Promptly upon completion or termination of a Study, CRO shall transfer to NovaCardia all Study Data resulting from such Study.

2.8 Publication Rights. CRO understands and agrees that participation in any multi-center clinical trial involves a commitment to publish the data from the clinical trial in a cooperative publication prior to publication or oral presentation of clinical trial results on an individual basis. CRO will ensure that NovaCardia approves, in writing, of all contractual provisions regarding the publication of results obtained pursuant to Studies.

2.9 Provision and Use of NovaCardia Product. NovaCardia shall, at its expense, provide CRO with sufficient amounts of the NovaCardia Product to be investigated in the Study to perform each Study on a timely basis. CRO agrees that the NovaCardia Product shall be used only for the applicable Study. Any unused NovaCardia Product shall be disposed of, or returned to NovaCardia, in accordance with NovaCardia instructions.

3. Payment and Budget.

3.1 Estimated Budget; Accounting. Each Task Order shall contain an estimated budget for the performance of the Task Order. CRO will provide to NovaCardia, at intervals stated in each Task Order, an accounting of costs incurred and accrued to date for Services under the applicable Study. CRO agrees its fees with respect to any Study will not exceed the estimated budget in the corresponding Task Order without the prior written approval of NovaCardia pursuant to a change order executed by the Parties. An estimated schedule of payments (the "Schedule of Payments"), inclusive of a down payment element of [...***...] of the total budget estimate, will be agreed with each Task Order. Any amounts prepaid pursuant to such required down payment element (the "Pre-Paid Amounts") shall be applied to the final set of payments due under the Schedule of Payments in like amount, unless applied earlier or reimbursed as set forth in Section 4 hereof.

3.2 Invoices; Payment. Unless otherwise agreed by the parties, CRO shall provide to NovaCardia for each Task Order a separate invoice at intervals agreed upon in the applicable Schedule of Payments, such invoice summarizing the Services performed during that period of time under that Task Order and the costs therefor. Each such invoice will specify the Task Order, and specific line items on the budget included in such Task Order, which are being invoiced. NovaCardia shall pay each undisputed invoice (of part thereof) within [...***...], in accordance with the Schedule of Payments. Invoices covering down payments required under any Schedule of Payments are due for payment within [...***...]

***Confidential Treatment Requested

[...***...] of the related Task Order. NovaCardia will notify CRO of any disputed invoiced amounts within [...***...], and the parties agree to work together in good faith to resolve any such disputes. CRO reserves the right to suspend services if overdue invoices are not settled within [...***...] from the date of written notice. Invoices for work performed in the United States will be issued in United States dollars and invoices for work performed outside of the United States will be issued in CHF, however such invoices in CHF will be converted into United States dollars. The conversion will be calculated using the average of the closing exchange rate of the first and last business days of the month prior to the month of invoicing, as such rates are published in the Wall Street Journal (Eastern edition).

All amounts stated in the Task Order are exclusive of any value added tax, sales tax and other like taxes and duties, as applicable. NovaCardia will be responsible for reimbursing CRO any such taxes, apart from corporate taxes, arising from Services provided under the Task Order, provided CRO gives NovaCardia written evidence of CRO's payment thereof.

3.3 Records Audit. CRO will maintain true and complete financial records relating to the Services. NovaCardia and/or an independent accounting firm appointed by NovaCardia, at NovaCardia's sole expense, subject to reasonable compensation to CRO for the time devoted by the CRO, shall have the right to audit CRO's financial records relating to a Study during the time such Study is ongoing under this Agreement and for [...***...] or such period of time as is required by applicable Code of Federal Regulations and ICH Guidelines; provided, that any such audit(s) shall be conducted upon reasonable advance notice to CRO and during CRO's normal business hours.

4. Term, Termination or Suspension of a Study or of the Agreement.

4.1 Term. The term of this Agreement shall commence on the Effective Date and shall continue until the later of five (5) years from the Effective Date or completion of all Services under any outstanding Task Orders, unless terminated sooner as provided in this Agreement.

4.2 Termination by NovaCardia. NovaCardia may terminate this Agreement, or, for any given Task Order, NovaCardia may terminate the applicable Task Order, and all CRO's Services under this Agreement and/or such Task Order for good cause, immediately upon written notice to CRO. Good cause shall include, without limitation, identification of any medical risk to Study participants, departure from CRO (or removal from a Study) of key individuals utilized by CRO with respect to the Services, a showing that the NovaCardia Product tested in a Study is not effective, receipt of notice of regulatory action by the Food and Drug Administration (the "FDA") (or any equivalent oversight body in a country other than the United States) terminating or suspending a Study.

4.3 Suspension of Work. Each Study may be suspended at any time by NovaCardia or any governmental agency, if, in the good medical judgment of the NovaCardia or any governmental agency, it is determined to be medically appropriate to do so. Suspension of work will be treated as a premature termination if Services are not requested resumed after [...***...] of suspension.

***Confidential Treatment Requested

4.4 Permissive Termination. NovaCardia may terminate this Agreement, and/or any Task Orders, without good cause on 90 days' written notice to CRO.

4.5 Termination of Agreement for Material Breach. Either party may terminate this Agreement and all Services hereunder then in progress, if the other party materially breaches this Agreement and fails to cure the breach within 30 days after receipt of written notice from the non-breaching party, specifying in detail the nature of the breach.

4.6 Payment upon Early Termination; Wind Down of Activities. In the event of early termination of any individual Task Order for a Study, or in the event of termination of this Agreement and all Task Orders for all Studies, as soon as possible after notice of termination is delivered hereunder, NovaCardia shall submit to CRO written instructions regarding the scope of Services to be provided by CRO in connection with termination of the Task Order(s). As soon as possible after receiving such instructions, CRO shall submit to NovaCardia a wind-down, close out, or transfer plan (the "Plan") to accomplish the remaining tasks and activities identified by NovaCardia's written instructions, and a budget for the remaining tasks and activities relating to the wind-down (the "Termination Budget"), with the final Plan and Termination Budget to be mutually agreed in writing. It is understood that NovaCardia shall reimburse foreseeable and customary expenses associated specifically with early termination, including without limitation any irrevocable commitments, contemplated in the applicable budget, by CRO made in reliance upon timely completion of the Study and expenses associated with winding down the Study. Notwithstanding the foregoing, in no event shall the Termination Budget, together with amounts otherwise paid by NovaCardia pursuant to the applicable budget, exceed the total amount payable to CRO under the budget for the applicable Task Order, insofar that NovaCardia has not requested any additional Services to be provided in addition to the initial scope. Subject to the application of any amounts paid as a downpayment by NovaCardia to CRO which have not been applied to amounts owed hereunder, NovaCardia shall pay to CRO: (a) within [...***...] of NovaCardia's receipt of documented evidence thereof, all reasonable and noncancellable costs incurred by CRO up to the date on which the notice of termination was sent (to the extent contemplated in the Budget for the applicable Task Order); and (b) all costs to be incurred by CRO in connection with its execution of the Plan (to the extent contemplated in the Termination Budget)(with [...***...] of such Termination Budget amounts (the "Initial Amount") to be due and payable within [...***...] of the parties' agreement upon the Termination Budget and the remaining [...***...] to be due and payable within [...***...] of NovaCardia's receipt of an invoice therefor for costs actually incurred after application of the Initial Amount). Any downpayment made under the Task Order will be taken duly into consideration at this point in time. Subject to the foregoing, upon delivery or receipt of notice of termination, as applicable, CRO shall use commercially reasonable efforts to minimize the extent of expenses that will be incurred with respect to this Agreement or any Task Order, as applicable, including notification to Participating Institutions to suspend the enrollment of any further subjects in the applicable Study or Studies. Notwithstanding the foregoing, to the extent CRO has received amounts from NovaCardia as prepayment for Services, including without limitation the Pre-Paid Amounts, in the event of early termination, such amounts shall be applied first to amounts owing to CRO by NovaCardia to ensure that NovaCardia pays for only those expenses actually incurred. Any remaining funds, if any, will be refunded to NovaCardia.

10. Medical Care Costs. NovaCardia agrees to be responsible for any reasonable and necessary medical care costs that are a direct result of a subject's participation in a Study that were not covered by third party payors and that are not the result of negligence, willful malfeasance or failure by any CRO Indemnitee to follow a material term of the applicable Task Order or Study Protocol.

without prior written permission of the other party, provided, NovaCardia may use, refer to and disseminate reprints of scientific, medical and other published articles which disclose the name of Hesperion consistent with applicable international copyright laws, provided such use does not constitute an endorsement of any commercial product or service by Hesperion. Notwithstanding the foregoing, either party may make such public disclosures as it determines, based on advice of counsel, are reasonably necessary to comply with laws or regulations.

13. Force Majeure. In the event of a delay caused by inclement weather, fire, flood, act of war, act of terrorism, act of God, or any like cause beyond the control of the parties, the party or parties so affected shall be excused from performance hereunder for the period of time attributable to such delay. The party affected shall give notice to the other party as provided herein.

Any attempted assignment of this Agreement not in compliance with this Article 16 shall be null and void.

This Agreement shall inure to the benefit of and be binding upon each party signatory hereto, its successors and permitted assigns, subsidiaries and affiliates.

16. English Language; Severability. This Agreement has been prepared in the English language, and the English language shall control its interpretation. If any provision of this Agreement is found by a court of competent jurisdiction to be unenforceable, then such provision will be construed, to the extent feasible, so as to render the provision enforceable, and if no feasible interpretation would save such provision, it will be severed from the remainder of this Agreement. The remainder of this Agreement will remain in full force and effect, unless the severed provision is essential and material to the rights or benefits received by either party. In such event, the parties will negotiate, in good faith, and substitute a valid and enforceable provision or agreement that most nearly implements the parties' intent in entering into this Agreement.

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