2.2 Laboratory work and scale-up activities

(a) Following the Commencement Date, Avecia shall carry out, and has carried out with respect to a portion thereof as set forth in the Interim Agreement, a range of activities, including

11

data acquisition and assessment, process transfer, replicate 15L runs, process characterisation, fermentation and downstream process, assay validation, process transfer and prep for large scale manufacture, laboratory based cleaning studies and centrifuge trials on two (2) 3000 litre Batches of the API, all as set out in more detail in the Work Programme.

(b) Centrifuge Trials.

(1) Obligations and Timing. Avecia shall carry out production of two (2) centrifuge trials on two (2) 3000 litre Batches of the API in accordance with its ABC5000 facilities’ Standard Operating Procedures, the Master Batch Records for the Process, all Applicable Laws and the terms and conditions of this Agreement. Avecia shall commence modifications of its ABC5000 facility for the centrifuge trials no later than week commencing July 4, 2005, Pacific Standard Time. If Avecia fails to commence the modifications of its ABC5000 facility necessary for the centrifuge trials before the expiration of the week commencing July 4, 2005, Pacific Standard Time, then Nuvelo is entitled to terminate this Agreement in accordance with Section 8.2 upon 10 calendar days written notice to Avecia, without payment of any Cancellation Fees if Avecia has not commenced the modifications before the expiration of the 10 calendar day period.

(2) Process Failures; Additional Centrifuge Work. If neither of the two centrifuge trials is successful for any reason other than an Avecia Default, then the Parties shall meet to agree to an additional phase of process development work, to include the performance of further centrifuge trials (all such work referred to herein as “Additional Centrifuge Work”) and commercially reasonable terms for the performance of the Additional Centrifuge Work. The Additional Centrifuge Work shall be set forth in a Programme Amendment Order, such Programme Amendment Order to include revised timings for Development Batch Manufacture and Validation Campaign, as appropriate. If, other than as a result of an Avecia Default, the Additional Centrifuge Work does not result in at least one successful centrifuge trial and Development Batch Manufacture has not commenced before the expiration of December 31, 2005, Pacific Standard Time, then Nuvelo may either terminate the Agreement in accordance with Clause 8.2 upon a date that is 30 calendar days after December 31, 2005, Pacific Standard Time or call an Urgent Meeting of the PSC to discuss whether further Additional Centrifuge Work should be conducted.

12

(3) Centrifuge Trials; Avecia Default. If neither of the two centrifuge trials is successful as a result of Avecia Default(s), Avecia shall promptly reprocess, rework if pre-approved in writing by an authorized representative of Nuvelo or re-perform, the centrifuge trials at Avecia’s cost and expense until either (i) one of the centrifuge trials is successful or; (ii) the centrifuge trials are unsuccessful other than as a result of an Avecia Default, at which time Clause 2.2(b)(2) will apply.

2.3 Development Batch Manufacture

(a) Batch Production. Avecia shall carry out production of two (2) Development Batches (in accordance with the terms set forth below) in its ABC5000 facility in accordance with the terms and conditions of this Agreement, cGMP, Applicable Laws and the Work Programme, with the primary aim of testing and improving Batch records and operating procedures, clarifying any scale-up issues and ensuring operator familiarity with the Process. Avecia also shall carry out an Engineering Batch in accordance with Clause 2.3(e). Whilst Development Batch Manufacture is intended to produce Development Batches which can be Released, it is recognised that problems related to the Process that are not Avecia Defaults may preclude this.

(b) Development Batch Failure. If the Quality Team is in agreement that neither of the two (2) Development Batches manufactured under Clause 2.3(a) can be Released, Avecia shall, at the direction and option of Nuvelo, either:

(1) reprocess one of the two (2) Development Batches produced during Development Batch Manufacture in accordance with cGMP;

(2) if pre-approved in writing by an authorized representative of Nuvelo, rework one of the two (2) Development Batches produced during Development Batch Manufacture in accordance with cGMP;

(3) manufacture another Development Batch; or

(4) immediately stop all work, as a result of a decision by Nuvelo to terminate the Agreement in accordance with Clause 8.

(c) Next Actions Upon Development Batch Failure.

(1) Avecia Default. In the event that the Quality Team is in agreement that the second Development Batch or both of the two (2) Development Batches manufactured under Clause 2.3(a) are Defective Batches as a result of an Avecia Default, Avecia shall rework, reprocess or

13

manufacture in accordance with Clause 2.3(b)—within 10 business days after the Quality Team notified the PSC of the Quality Team’s determination if the Avecia Default is of a nature that can be promptly corrected, otherwise, as soon as reasonably practicable thereafter—at Avecia’s cost and expense, until such time as Avecia generates a Development Batch that can be Released (or could have been Released but for an issue that is not an Avecia Default); but if, as a result of Avecia Default(s), Avecia fails to generate a Development Batch which can be Released within 3 months from commencement of such rework, reprocessing or further manufacture, then the PSC shall hold an Urgent Meeting to discuss whether or not yet another Development Batch should be generated. Nuvelo is entitled to terminate the Agreement, without payment of any Cancellation Fees, if Development Batches cannot be Released as a result of Avecia Default(s) before the expiration of the 3 month cure period provided in this Clause 2.3(c)(1). Nuvelo may terminate the Agreement during the 3 month cure period for Unremedied Breach if Avecia fails to generate a Development Batch that can be Released as a result of Avecia Default(s) and is not using commercially reasonable efforts to generate at least one Development Batch that can be Released per month during the three month cure period.

(2) Process Failure. If the first 2 Development Batches cannot be Released for a reason other than Avecia Default, at the request of Nuvelo, Avecia shall rework, reprocess or manufacture Development Batches at a time and at a cost to Nuvelo to be agreed by the Parties in good faith and recorded in a Programme Amendment Order. If the rework, reprocessing or further manufacture results in another Development Batch which is a Defective Batch for a reason other than Avecia Default, then the PSC shall hold an Urgent Meeting to discuss whether or not yet another Development Batch should be generated. If and at such time as Avecia and Nuvelo agree that Process scale-up problems causing the Defective Batches in accordance with this Clause 2.3(c)(2) are or will be satisfactorily resolved, unless the Agreement is terminated by one the Parties, the Parties will agree to a revised timetable for manufacture of a number of Development Batches to be determined, upon commercially reasonable terms, in a Programme Amendment Order.

(d) Successful Development Batch Release: Pre-Validation Campaign Review. If at least one (1) of the two (2)

14

Development Batches manufactured under Clause 2.3(a) can be Released or if rework, reprocessing or further manufacture carried out in accordance with Clause 2.3(b) results in a Development Batch which can be Released, the Project Steering Committee shall review the activities carried out to date, solely to evaluate operability of the Process and Avecia’s cGMP compliance in order to ensure that both Parties are confident of success in the Validation Campaign (“the Pre-Validation Campaign Review”). During the Pre-Validation Campaign Review, the PSC, with input from the Quality Team, shall discuss readiness to carry out the Validation Campaign, potential timing for its conduct and any other issues concerning the Process operability or cGMP compliance. This discussion will include a review and analysis of the actual performance of the Development Batches compared to the Process Assumptions, and an attempt by the PSC to reach agreement with respect to whether the Validation Campaign shall be delayed, not be delayed, or not be carried out at all. If during the Pre-Validation Campaign Review, the EC, after referral of the matter to it by the Project Steering Committee, is unable to reach a final decision in accordance with the terms of Clause 2.7(f) as to whether the Validation Campaign shall be delayed, not be delayed, or not be carried out at all—solely due to Process operability or Avecia cGMP compliance issues, or any other concerns which resulted in a Development Batch being a Defective Batch— then either Party may terminate this Agreement in accordance with and subject to the terms provided for termination set forth in this Agreement, including the possibility that the Parties may mutually agree to terminate the Agreement under Clause 8.4.

(e) Proceeding to Validation Campaign. If at least one (1) Development Batch is Released, then following completion of, and subject to either agreement by the PSC or a determination made by the EC in the Pre-Validation Campaign Review, Avecia shall carry out an Engineering Batch and shall proceed to and shall carry out the Validation Campaign in accordance with the terms and conditions of this Agreement for the performance of the Project in accordance with Clause 2.1, the Work Programme and any revised timetable for performance of the Engineering Batch and the Validation Campaign resulting from Pre-Validation Campaign Review. Development Batch Manufacture shall be deemed to be complete when: (1) the Quality Team has completed Release of at least one Development Batch, and that Batch’s associated documentation has been delivered to Nuvelo; and (2) Avecia has completed manufacture of an Engineering Batch that is not a Defective Batch, and the Engineering Batch’s associated documentation has been delivered to Nuvelo.

15

(f) Delivery of Defective Batches. In the event that during Development Batch Manufacture it is determined by the Quality Team that a Development Batch is a Defective Batch, the Defective Batch shall not be delivered to Nuvelo, unless Nuvelo requests it. If Nuvelo requests delivery of the Defective Batch, Avecia shall deliver such Defective Batch in accordance with Clause 4.2 and such Defective Batch may be used in research or development internally, labelled for non-human use or destroyed.

(g) Quality Team Disagreement. If the Quality Team cannot reach agreement with respect to whether or not a Development Batch is a Defective Batch, or whether or not a Defective Batch resulted from an Avecia Default, the disagreement will be resolved in accordance with Clause 2.7(g).

2.4 Validation Campaign

(a) cGMP Preparation

(2) Number of Validation Batches. Subject to Clause 2.4(b)(3) below, the Validation Campaign shall consist of up to five (5) Validation Batches with an expectation of producing three (3) Released consecutive successful production Batches and thus constitute a formal Validation Campaign. Avecia will ensure that sufficient time is scheduled in its ABC5000 facility to complete a Validation Campaign of up to five (5) Validation Batches.

(3) 5^th Validation Batch. In the event that the Quality Team determines that a fifth (5^th) Validation Batch is required, other than as a result of an Avecia Default, in order to increase the chances of successful completion of the Validation Campaign, Avecia shall carry out manufacture of a fifth (5^th) Validation Batch on the basis that Avecia will meet the costs of operating its ABC 5000 facility and Nuvelo shall pay to Avecia, as an additional technical consultancy fee, the actual Expenditures for any additional raw materials or consumables required to be purchased in order to manufacture such fifth (5^th) Validation Batch, plus the Handling Fee, in accordance with Clause 3.2(b).

(4) Documentation Review. During the Validation Campaign, the Parties shall carry out review of the Master Batch Records, campaign Batch records and other relevant documentation relating to each Validation Batch as it is manufactured. This review and assessment will involve the Nuvelo Quality Unit and such other of Nuvelo’s staff as Nuvelo directs, in Nuvelo’s discretion.

(5) Completion of Validation Campaign. The Validation Campaign shall be deemed to be complete when the Quality Team determines that the Validation Campaign has completed three (3) Validation Batches that can be designated consecutive successful production Batches that have completed Release, and all associated documentation and a validation summary report have been delivered to Nuvelo in accordance with Clause 4.2.

17

(c) Quality Unit Determination

(1) Determination of Validation Success or Failure. The Quality Team shall determine in accordance with the Quality Agreement and by reference to cGMP whether the Validation Campaign has been successful. In the event that the Quality Team determines that the Validation Campaign has not been successful, then, as set forth in and in accordance with Clauses 2.4(c)(2) and 2.4(c)(3) below, Avecia shall repeat the Validation Campaign or Validation Batches (as appropriate) within 10 business days after the Quality Team notified the PSC of the Quality Team’s determination, if the cause of the failure of the Validation Campaign is of a nature that can be promptly corrected, otherwise, as soon as reasonably practicable thereafter. In the event of any dispute arising amongst the Quality Team, the matter will be resolved in accordance with Clause 2.7(g).

(2) Avecia Default. If the Validation Campaign is determined not to be successful as a result of an Avecia Default, then the repeated Validation Campaign or Validation Batches (as appropriate) shall be promptly carried out by Avecia at Avecia’s cost and expense; but if the repeated Validation Campaign or Validation Batches (as appropriate) does not result in a successful Validation Campaign as a result of an Avecia Default within 3 months of commencement of such repeated Validation Campaign or Validation Batches (as appropriate), then the PSC shall hold an Urgent Meeting to discuss whether or not the Validation Campaign or Validation Batches (as appropriate) shall be repeated again. Nuvelo is entitled to terminate the Agreement, without payment of any Cancellation Fees, if, as a result of Avecia Default, the repeated Validation Campaign or Validation Batches (as appropriate) does not result in a successful Validation Campaign before the expiration of the 3 month cure period provided in this Clause 2.4(c)(2). Nuvelo may terminate the Agreement during the 3 month cure period for Unremedied Breach if Avecia fails to generate a successful Validation Campaign and is not using commercially reasonable efforts to generate at least 5 Validation Batches that could lead to a successful Validation Campaign during the three month cure period.

(3) Validation Process Failure. If the Validation Campaign is determined not to be successful because of a Validation Process Failure, then, if requested in writing by Nuvelo, a repeated Validation Campaign or Validation Batches (as appropriate) shall be carried out by Avecia at a commercially reasonable cost to Nuvelo to be agreed in good faith by the Parties and set out in

18

a Programme Amendment Order. In the event that a repeated Validation Campaign carried out under this Clause is determined not to be successful, then the Parties shall meet to discuss what action should be taken.

(d) Quality Team Disagreement. If the Quality Team cannot reach agreement with respect to whether or not a Validation Batch is a Defective Batch, or whether or not a Defective Batch resulted from an Avecia Default, the disagreement will be resolved in accordance with Clause 2.7(g).

2.5 Delays and Cancellations. Nuvelo shall have an option to, and otherwise may as a result of an Avecia Default, delay commencement of, or cancel Development Batch Manufacture or the Validation Campaign. The Parties also acknowledge that delays may occur as a result of Process Failures, as set forth below. In the event that Nuvelo decides to exercise such option or take such action, the following provisions shall apply:

(a) Notice. Nuvelo shall give written notice to Avecia of its intention to delay or cancel Development Batch Manufacture or the Validation Campaign (as appropriate), and, in the case of delay, setting out the estimated length, or circumstances that would dictate the length, of the delay. Notice is deemed given at such time as either Party notifies the other Party in writing that the Validation Campaign will be delayed as a result of a Process Failure, and in such case, the PSC shall determine the estimated length of the delay.

(b) Cancellation Fees; Non-Manufacturing Delays or Cancellation. With respect to any cancellation or Non-Manufacturing Delay, Nuvelo shall pay to Avecia the Cancellation Fees in consideration for technical consultancy into the effect of such Non-Manufacturing Delay or cancellation on the Project.

(c) Process Failure Delay Fee. With respect to any delay of the Validation Campaign resulting from a Process Failure that results in a delay of the completion of the usage of Avecia’s manufacturing facilities for the Validation Campaign by more than two weeks after August 16, 2006, Nuvelo shall pay to Avecia, in consideration for technical consultancy into the effect of such delay on the Project, the sum of £212,470 pounds per week (the “Process Failure Delay Fee”) for each week beyond the expiration of two weeks after August 16, 2006, during which the completion continues to be delayed, until such time as Nuvelo has paid to Avecia an amount in Process Failure Delay Fees that is equal to the lesser of: £2,550,000 pounds; or the amount Nuvelo would have paid to Avecia in Cancellation Fees if notice had been given regarding a Non-Manufacturing Delay instead of a delay

19

resulting from a Process Failure. Avecia shall make commercially reasonable endeavours to raise revenue by utilising the production facility during the period during which the Validation Campaign was intended to take place but for the delay. Avecia shall refund to Nuvelo a sum equivalent to the revenue (net of raw materials and consumables Expenditure) raised as a result of such alternative use up to a maximum of 80% of the technical consultancy fee paid under this Clause 2.5(c). For the purposes of this Clause 2.5(c), “Process Failure” means the occurrence of a Defective Batch that results from a factor—other than any of the factors listed in paragraphs (a) through (d) of the definition of Avecia Default—which affects the Process or production of the API and was not known and could not reasonably have been known by Avecia prior to the time at which the factor became known, including, without limitation, a previously unknown factor not studied either as part of the Amgen programme transferred to Avecia or the Avecia laboratory work programme carried out pursuant to the Project.

(d) Delay. The Parties shall meet to discuss availability of Avecia’s manufacturing facility for the delayed Development Batch Manufacture or the Validation Campaign (as appropriate) in accordance with Clause 2.3 and 2.4 and, except with respect to any delay resulting from or arising out of an Avecia Default, Nuvelo’s refusal to take a license under a Patented, Licensed Avecia Invention under Clause 5.2(c) or failure of the centrifuge trials, if the delay is in excess of six (6) months, a commercially reasonable amount payable by Nuvelo to Avecia in respect of such later commencement of Development Batch Manufacture or the Validation Campaign (as appropriate).

(e) Effect of Delay on Project. Except with respect to a delay resulting from or arising out of an Avecia Default or Nuvelo’s refusal to take a license under a Patented, Licensed Avecia Invention under Clause 5.2(c), Avecia shall not be obliged to carry out the delayed Development Batch Manufacture or the Validation Campaign (as appropriate) until the Parties have reached agreement on the later commencement thereof, but will use reasonable commercial endeavours to reschedule the availability of its facility and appropriate personnel. In the case of a delay resulting from an Avecia default, if Nuvelo decides to have Avecia proceed with Development Batch Manufacture and/or the Validation Campaign, Avecia shall carry out the delayed Development Batch Manufacture or Validation Campaign in accordance with the terms and conditions set forth in Clauses 2.3 and 2.4.

(f) Effect of Cancellation. Where Nuvelo elects to cancel Development Batch Manufacture, Avecia shall not be obliged to carry out the Validation Campaign, and except with respect

20

to any cancellation resulting from or arising out of an Avecia Default or failure of the centrifuge trials, the Validation Campaign shall also be deemed cancelled with effect from the date of notice of Nuvelo’s intention to cancel Development Batches Manufacture and the Validation Campaign.

2.6 Nuvelo Delay.

(a) In the event of a Nuvelo Delay, Avecia and Nuvelo will use reasonable commercial endeavours to minimize such Nuvelo Delay or, subject to agreement by both Parties, to adjust the Development Batch Manufacture or the Validation Campaign schedule to accommodate such delay. Any Nuvelo Delay which cannot be avoided shall be considered to be Hold Time in respect of the affected Batch.

(b) In the event that a Nuvelo Delay results in an inability for Avecia to carry out the Development Batch Manufacture or the Validation Campaign in accordance with the mutually agreed schedule therefor, then the Parties shall meet to discuss availability of Avecia’s manufacturing facility for the delayed Development Batch Manufacture or the Validation Campaign (as appropriate), and a commercially reasonable amount payable by Nuvelo to Avecia in respect of such later commencement of Development Batch Manufacture or the Validation Campaign (as appropriate).

(g) Dispute Resolution for Batch Disputes. If a dispute arises amongst the Quality Team relating to whether or not a Batch of the API is a Defective Batch, or whether or not a Defective Batch results from or arises out of an Avecia Default (each of the preceding a “Batch Dispute”), such Batch Dispute shall be resolved as follows.

(1) The Quality Team shall immediately notify the Project Steering Committee (PSC) in writing (the “Batch Dispute Notice”) that a Batch Dispute exists amongst the Quality Team. The Quality Team will discuss the Batch Dispute in good faith to attempt to reach agreement on: (i) whether a Batch is a Defective Batch and, if so, what course of action shall be taken to address it; and (ii) whether or not a Defective Batch resulted from or arose out of an Avecia Default.

(2) In the event that the Quality Team fails to reach agreement on a Batch Dispute within 15 calendar days after sending the Batch Dispute Notice to the PSC, the Quality Team shall immediately refer the Batch Dispute to the PSC for discussion, by written notice to the PSC. Once the Batch Dispute has been referred to the PSC, the PSC has 5 business days from receipt of the referral notice to either resolve the Batch Dispute or

24

refer the Batch Dispute to an independent expert or laboratory, with the expertise necessary to reasonably resolve the Batch Dispute.

(3) If the PSC cannot resolve the Batch Dispute or agree upon an independent expert or laboratory to resolve the Batch Dispute before the expiration of 5 business days after receiving the referral notice, the PSC shall immediately notify the EC of its failure in writing. Within no later than 2 business days after receiving notice of the failure from the PSC, each EC member shall nominate an independent expert who shall not: be a current or former employee, consultant or agent of a Party; have an immediate family member who is an employee, consultant or agent of a Party; or have any financial interest in a Party. Promptly thereafter, those two independent experts shall agree on a third independent expert who shall use any reasonable information, materials and data provided to him or her by the other two experts within 10 business days after his or her agreement to act as the third independent expert, to either promptly resolve the Batch Dispute or determine which independent Third Party laboratory will conduct the work necessary to promptly resolve the Batch Dispute. Such referral shall be solely for the purpose of establishing whether or not the applicable Batch is a Defective Batch and whether or not any Defective Batch results from or arises out of an Avecia Default. The decision of the independent expert, or independent laboratory, shall be made in writing and shall be binding upon the Parties. Whichever Party failed to accurately assess whether the Batch was or was not a Defective Batch, or whether or not a Defective Batch resulted from or arose out of an Avecia Default, shall bear the full cost and expense associated with the hiring and performance of the independent experts and/or laboratory.

2.8 Programme Amendment Orders. The Parties may agree to vary the Project and sums to be paid under Clause 3 as a result of a Project variation, so long as such variation is made in writing in a Programme Amendment Order. The Parties recognize that any of the following will require changes to the Work Programme that may cause a change in payments set out in Clause 3:

(a) Nuvelo requires Avecia to carry out additional or different work to that specified in the Work Programme set forth in Schedule 1; or

(b) the actual circumstances encountered in carrying out the Project differ from the then current Process Assumptions; or

25

(c) in the event that there is a delay to the Project for any reason other than Avecia Default or Nuvelo’s refusal to take a license under a Patented, Licensed Avecia Invention, including a Nuvelo Delay; or

(d) in the event that Additional Centrifuge Work is required as a result of a failure, other than one attributable to an Avecia Default, of the centrifuge trials pursuant to Clause 2.2(b); or

(e) Hold Time, but excluding Hold Time resulting from or arising out of: (1) an Avecia Default or (2) Nuvelo’s refusal to take a license under a Patented, Licensed Avecia Invention.

3.3 Equipment. In order for Avecia to provide technical consultancy services work under this Agreement, it will be necessary for certain items of Equipment to be purchased by Avecia. Avecia will be authorised to proceed with the relevant services for which the Equipment is required on the following terms:

(a) Avecia shall obtain, from an independent Third Party, at least 2 quotations for each item of Equipment and send a copy of the quotations by fax or email to Nuvelo and Nuvelo shall inform Avecia within 5 business days of receipt which

33

quotation Nuvelo approves and whether it authorises Avecia to proceed with the services for which the item of Equipment is required. In the absence of such approval, Avecia shall not proceed with the relevant services.

(b) If Nuvelo gives its approval to the relevant quotation, Avecia shall be considered authorised to proceed with the relevant services set forth under the Work Programme or agreed upon Program Amendment Order and shall purchase the item of Equipment for such purpose. Any Equipment purchased by Avecia shall be dedicated to the Project, and shall not be used for any other use or purpose. Avecia shall keep the Equipment in good working order. The purchase price of the item of Equipment per the approved quotation shall thereupon form part of the consideration for the provision of the technical consultancy services (including qualification, quality assurance and quality control activities) by Avecia and Avecia shall invoice Nuvelo for: (i) such amount; and (ii) the Handling Fee.

(c) Following completion or termination of the Project, whichever occurs first, at any time within 12 months following such completion or termination, Nuvelo shall be entitled to purchase all or any portion of the Equipment from Avecia for the sum total of £1.00 in its or their then current, good working condition, subject to payment of any outstanding and undisputed fees by Nuvelo to Avecia for work carried out under this Agreement in accordance with the terms and conditions of this Agreement and the Work Programme.

(d) Nuvelo shall provide to Avecia reasonable prior written notice of its wish to purchase the Equipment so as to minimize any unplanned facility downtime and Nuvelo shall be responsible for all commercially reasonable removal costs and expenses. If the removal of any Equipment is performed by Nuvelo personnel, Nuvelo agrees to pay for the making good of any damage caused to Avecia’s facility as a result of such removal. If the removal is performed by Avecia personnel, Avecia agrees to pay for the making good of any damage caused to the Equipment being removed as a result of such removal.

3.4 Invoices and Timing of Payments. Avecia shall promptly issue invoices for the sums set out in Clauses 3.1, 3.2 and 3.3 once such sums become payable in accordance with Clauses 3.1, 3.2 and 3.3. In respect of invoices in respect of sums set out in Clause 3.1, Nuvelo shall pay invoices received by Nuvelo on or before the 15^th day of each month by the end of that month and shall pay invoices received by Nuvelo after the 15^th day of each month by the end of the following month. In respect of invoices in respect of sums set out in Clause 3.2, Nuvelo shall pay such sums within 30 calendar days after Nuvelo’s receipt of the relevant invoice. In respect of

34

invoices in respect of sums set out in Clause 3.3, Nuvelo shall pay such invoices within ten (10) business days after receipt of the relevant invoice. Payments shall be made in Pounds Sterling.

3.5 Bank Account Details. All amounts payable to Avecia under this Agreement shall be paid by wire transfer, quoting invoice numbers of payment, to an account number specified in writing by Avecia.

3.6 Taxes. Any payment under this Agreement is stated exclusive of any Value Added Tax. It is the understanding of both Parties that the technical consultancy services being provided under this Agreement are outside the scope of UK VAT. However, in the event that UK VAT does become payable, the UK VAT shall be for the account of Nuvelo and Avecia shall use best efforts to assist Nuvelo in seeking recovery of such tax paid from the UK HM Customs and Excise. If Nuvelo is otherwise required to withhold tax applicable to any payment under this Agreement, Nuvelo shall promptly provide Avecia with the official receipts and such other evidence of payment as Avecia may reasonably request and Nuvelo shall render Avecia reasonable assistance in order to allow Avecia to obtain the benefit of any relevant present or future double taxation treaty.

3.7 Financial Tracking; Reporting. The PSC and Nuvelo’s financial team representatives will review and measure the growth in value of the Project by tracking resources used versus progress against the deliverables set out in the Work Programme. In respect of consumables, raw materials and any other items purchased by Avecia under Clause 3.2, Avecia will provide a breakdown by item and include copies of invoices for those items of an individual price of greater than £5,000, to the PSC and Nuvelo’s financial team representatives. Within 3 business days after the end of each month, Avecia will provide a financial ‘Earned Value Analysis’ report for that month to Nuvelo. Utilizing the Payment Schedule set forth in Clause 3.1, the report will summarize the approximate value of services provided to Nuvelo for each Project stage that Avecia actively performed during that month. Upon written request by Nuvelo, Avecia shall provide, within thirty days of receipt of Nuvelo’s written notice, documented proof of purchase for all Expenditures and Equipment, or for specified Expenditures and Equipment, passed through to Nuvelo in accordance with Sections 3.2, 3.3 and 3.4. Avecia will provide Nuvelo with a quarterly written report at each regular PSC meeting setting forth the activity status of its manufacturing suite(s) that are intended to be used or could be used for the Project, for the six months following the date of submission of the report to Nuvelo. The report will set forth the times when Avecia’s suites are available and when they are committed to other projects.

4. Completion of the Project

4.1 Completion. Completion of the Project will be deemed to have occurred when the Development Batch Manufacture, the Validation Campaign and any additional or alternative work agreed in a Programme Amendment Order have been completed.

4.2 Packaging, Shipping and Delivery. Deliveries of all material, including documentation, returned consumable items or Equipment under Clauses 3.2 or 3.3, and API will be made Ex Works, Avecia’s Billingham facility (Incoterms 2000), subject to the following. Avecia is responsible for packaging and labelling the API in anticipation of shipment. Avecia also shall employ a shipper, reasonably acceptable to Nuvelo, for the shipment of all Released API and any Defective Batch. Avecia will package the Released API or Defective Batch in validated containers under validated shipping conditions. Until the shipping conditions have been validated, Avecia will package the Released API or Defective Batch with temperature monitoring devices that are able to function properly during the shipping process, as further set forth in the Quality Agreement. Risk of loss for all Released API or Defective Batch shall transfer to Nuvelo after delivery of the Released API or Defective Batch to the Nuvelo-approved shipper by Avecia, except with respect to any loss resulting from a failure of Avecia to properly package and label the API for shipment. Nuvelo will purchase insurance to cover any loss to the Released API or Defective Batch once it is delivered to the shipper. Nuvelo agrees that it shall export the API sold to it promptly and in any case within 3 months of the final stage payment for the API and shall provide evidence of such export within 3 months thereof.

4.3 Payment on Completion. Nuvelo shall pay to Avecia within thirty (30) calendar days after Completion any sums required to be paid pursuant to Clause 3.2 above which may remain outstanding at Completion. Upon Completion, Nuvelo shall pay any sums for milestones triggered pursuant to Clause 3.1 in accordance with the payment terms set forth in Section 3.4.

4.4 Irrevocable Option for Future Manufacturing Period.

(a) Avecia hereby grants Nuvelo an irrevocable option (the “Manufacturing Option”) to purchase, upon commercially reasonable terms to be agreed under Clause 4.4(c) below, 3 kilograms of Released API (“the Manufacturing Quantity”), to be manufactured in the stream in Avecia’s ABC5000 facility

36

in which the Process was validated under this Agreement, during the period commencing April 1, 2007 and expiring October 31, 2008 (“the Manufacturing Option Period”).

(b) Following signature of this Agreement and whilst this Agreement remains in force, Nuvelo shall use reasonable commercial endeavours to provide Avecia with an estimate regarding the potential timing of the Manufacturing Quantity during the Manufacturing Option Period. The obligation to provide the estimate will commence on Release of the first Validation Batch and the forecast will be updated at each PSC meeting or on Nuvelo becoming aware of a change in its timeline if earlier. To exercise the Manufacturing Option, Nuvelo shall give Avecia written notice of its exercise not later than 1 calendar year before the date that Nuvelo expects Avecia to deliver the Manufacturing Quantity to Nuvelo. In the absence of providing Avecia with timely written election, the option in Clause 4.4(a) shall lapse.

(c) No later than 30 calendar days after commencement of the Validation Campaign, Avecia and Nuvelo shall promptly commence negotiations in good faith for the supply of the API by Avecia to Nuvelo upon commercially reasonable terms (“Supply Agreement”). The Supply Agreement is anticipated to contain provisions related to anticipated volumes, pricing, forecasting mechanisms and quality control provisions, and such other commercially reasonable provisions. The Parties shall use reasonable commercial efforts to commence discussions regarding possible key principles of any Supply Agreement after the first successful Release of a Development Batch. Nuvelo shall have no obligation to enter into the Supply Agreement and may immediately halt negotiations at any time, as a result of an Avecia Default.

If Nuvelo terminates this Agreement for Unremedied Breach by Avecia, Avecia shall be liable for any currency exchange rate losses incurred by Nuvelo up through and until January 1, 2007, as a result of commitments made by Nuvelo to enable Nuvelo to pay Avecia the payments set forth in Clause 3.1 in British pounds sterling. Within 5 business days after the effective date of termination of the Agreement for Avecia’s Unremedied Breach, Nuvelo shall arrange to sell all British pounds sterling purchased by Nuvelo in anticipation of its obligation to make future payments under this Agreement, and Nuvelo shall also arrange to sell all contracts to purchase British pounds sterling purchased by Nuvelo in anticipation of its obligations to make future payments under this Agreement. Avecia shall pay to Nuvelo an amount equal to any currency exchange losses actually incurred by Nuvelo in connection with such sales, as reduced by any amounts owed by Nuvelo to Avecia as of the effective date of termination on account of services completed by Avecia in compliance with and prior to termination of this Agreement. Avecia will pay any undisputed amounts owed to Nuvelo under this Clause 9.1(c) within five (5) business days of its receipt of an invoice for such amounts from Nuvelo. All payments to Nuvelo under and in accordance with this Clause 9.1(c) will be made in United States dollars.

(d) Subject to Section 6.5, the rights and remedies set out in this Clause 9.1 in respect of the consequences of termination do not limit any other remedies or damages to which a Party may be entitled in law or in equity.

9.2 Acquired Rights. Termination or expiry of this Agreement, for whatever reason, shall not prejudice the rights of either Party

If a dispute arises amongst the Quality Team relating to whether or not a Batch of the API is a Defective Batch, or whether or not a Defective Batch results from or arises out of an Avecia Default (each of the preceding a “Batch Dispute”), such Batch Dispute shall be resolved as follows.

(1) The Quality Team shall immediately notify the Project Steering Committee (PSC) in writing (the “Batch Dispute Notice”) that a Batch Dispute exists amongst the Quality Team. The Quality Team will discuss the Batch Dispute in good faith to attempt to reach agreement on: (i) whether a Batch is a Defective Batch and, if so, what course of action shall be taken to address it; and (ii) whether or not a Defective Batch resulted from or arose out of an Avecia Default.

(2) In the event that the Quality Team fails to reach agreement on a Batch Dispute within 15 days after sending the Batch Dispute Notice to the PSC, the Quality Team shall immediately refer the Batch Dispute to the PSC for discussion, by written notice to the PSC. Once the Batch Dispute has been referred to the PSC, the PSC has 5 business days from receipt of the referral notice to either resolve the Batch Dispute or refer the Batch Dispute to an independent expert or laboratory, with the expertise necessary to reasonably resolve the Batch Dispute.

(3) If the PSC cannot resolve the Batch Dispute or agree upon an independent expert or laboratory to resolve the Batch Dispute before the expiration of 5 business days after receiving the referral notice, the PSC shall immediately notify the EC of its failure in writing. Within no later than 2 business days after receiving notice of the failure from the PSC, each EC member shall nominate an independent expert who shall not: be a current or former employee, consultant or agent of a Party; have an immediate family member who is an employee, consultant or agent of a Party; or have any financial interest in a Party. Promptly thereafter, those two independent experts shall agree on a third independent expert who shall use any reasonable information, materials and data provided to him or her by the other two experts within 10 business days after his or her agreement to act as the third independent expert, to either promptly resolve the Batch Dispute or determine which independent Third Party laboratory will conduct the work necessary to promptly resolve the Batch Dispute. Such referral shall be solely for the purpose of establishing whether or not the applicable Batch is a Defective Batch and whether or not any Defective Batch results from or arises out of an Avecia Default. The decision of the independent expert, or independent laboratory, shall be made in writing and shall be binding upon the Parties. Whichever Party failed to accurately assess whether the Batch was or was not a Defective Batch, or whether or not a Defective Batch resulted from or arose out of an Avecia Default, shall bear the full cost and expense associated with the hiring and performance of the independent experts and/or laboratory. .

Appendix 1

Glossary of Terms

API: Active Pharmaceutical Ingredient.

cGMP: Current Good Manufacturing Practice.

ICH: International Conference on Harmonization.

Certificate of Analysis: A compilation of the analytical test methods applied, specifications for each test and test results for a particular intermediate/finished API lot. The certificate should be reviewed and approved by QA management.

Certificate of Conformance: Certification confirming that an intermediate or finished API has been manufactured in compliance to the cGMP’s and that quality records associated have been reviewed and approved by QA management.

Commercial Agreement: the Agreement effective 21 January 2005 for the manufacture of the API by and between Avecia and Nuvelo.

Approved Suppliers: Suppliers approved within Avecia’s quality system and qualified using FDA/EU guidelines, and approved by Nuvelo.

Key Suppliers: Suppliers that supply key ingredients for the manufacture of the API. Change to these Suppliers would impact the API quality.

OOS: Out of Specification.

OOT: Out of Trend.

NIST: National Institute of Standards.

In-Process Control: Checks performed during production to monitor and if appropriate, to adjust the process and/or to ensure that the API conforms to the specifications attached to the QA Agreement as Appendix 6.

Critical Non-conformance: A non-conformance which would impact API quality.

Major Non-conformance: A non-conformance which has a potential to impact API quality and requires an investigation to assess the impact on API quality.

Minor Non-conformance: A non-conformance which has no impact on API quality

Reprocess: Reprocess is defined as repeat processing of a manufacturing step that does not affect the disposition of the API. For example: a 0.22 micron filtration when the filter integrity failed.

Rework: Upon prior written approval of Nuvelo, rework may occur on identification of a non-conformance associated with the finished API (this applies to intermediate stages of API also) that may affect the API quality. Rework is only performed upon the prior written approval of Nuvelo as a result of an investigation through the non-conformance reporting process or as a result of a change that occurred in the drug master file (ex: expiration date). For example: Relabeling of vials due to incorrect sample lot #. This would lead to an non-conformance and then the change would be approved by Nuvelo before commencement of the rework .
