8.2 Celltech may reject and will not be obliged (but will always be entitled) to purchase any Batches having an unacceptable yield. The Acceptable Yield is to be agreed on a Product by Product, and Campaign by Campaign basis in the following way:

8.2.1 An initial Acceptable Yield will be calculated on the basis of 80% of the average of the three highest yields of the Pilot Scale data, adjusted for working volume of the relevant Fermentation Suite;

8.2.2 The initial Acceptable Yield will be used for the first Batch manufactured in the BPMSS or BPMLS. If the first Batch does not meet the Acceptable Yield, both parties will meet to discuss whether the Process is performing satisfactorily, and whether to proceed with the process of recalculation of the Acceptable Yield according to Clause 8.2.3;

8.2.3 The Acceptable Yield will be recalculated after the first 3 (three) Batches have completed Manufacture in the BPMSS or BPMLS, on the basis of 80% of the average yield of those 3 (three) batches. The recalculated yield will be used as the Acceptable Yield;

8.2.4 The Acceptable Yield of each Product will be reviewed by both parties prior to a subsequent Campaign of Manufacture, to determine whether any adjustment should be made based on previous manufacturing experience of that Product. An adjustment of the Acceptable Yield will be made if the average yield of all Batches of that Product Manufactured in all previous Campaigns has increased by greater than 20% of the average yield on which the existing Acceptable Yield was calculated. In the event that an adjustment is required, the revised Acceptable Yield will be calculated on the basis of 80% of the average across all previous batches.

15

8.3 Upon receipt of a Batch of Product by Celltech or its designee, Celltech or its designee may analyse the sample taken from the Batch and supplied by Lonza with the Batch pursuant to Clause 7.3. If the analysis of the sample shows that the Product fails to meet the Specification or the Acceptable Yield, Celltech shall give Lonza written notice thereof rejecting such Product.

8.4 If Lonza receives written notice of rejection of a Batch by Celltech under Clause 8.3 above the following procedures shall apply:

(a) If the Batch of Product fails to meet the Specification or Acceptable Yield or is non-cGMP compliant and Lonza accepts the details submitted by Celltech, Lonza shall, at Celltech’s discretion, either (i) supply to Celltech at no additional cost a replacement quantity of Product or (ii) not charge Celltech for such Batch. If payment has already been made by Celltech for such Batch then Lonza shall promptly refund such payment, and if payment has been made by Celltech at the Introductory Rate, Lonza shall also pay Celltech an additional amount equal to the difference between the Introductory Rate and the Base Rate for such Batch.

(b) If Product fails to meet the Specification or Acceptable Yield or is non-cGMP compliant, and Lonza does not accept the details submitted by Celltech, then within (thirty) 30 days from the date on which the details of Celltech’s rejection are received by Lonza, Lonza will appoint an independent scientific and technical expert (or, in the case of cGMP compliance rejection, a regulatory expert) acceptable to Celltech to:

(i) review the results of any tests relied upon by Celltech in support of its rejection;

(ii) repeat the tests performed by Celltech using the two Batch samples retained by Lonza pursuant to Clause 7.3;

(iii) decide if the Batch of Product was properly rejected.

(c) The findings of the expert shall be final and conclusively binding on the parties as to whether such Batch of Product is cGMP compliant, complies with the Specification or meets the Acceptable Yield. If the analysis of the expert does not confirm Celltech’s rejection, Celltech shall pay for any fees and costs of the expert and shall be entitled to accept and pay for the Batch in question. If the analysis of the expert does confirm

16

Celltech’s rejection, Lonza shall pay for any fees and costs of the expert and, at Celltech’s discretion, either (i) supply to Celltech at no additional cost a replacement quantity of Product or (ii) not charge Celltech for such Batch. If payment has already been made by Celltech for such Batch then Lonza shall promptly refund such payment, and if payment has been made by Celltech at the Introductory Rate, Lonza shall also pay Celltech an additional amount equal to the difference between the Introductory Rate and the Base Rate for such Batch.

9. FORECASTING AND ORDERING RESERVED CAPACITY

Reserved Capacity

9.1 For the calendar years 2004 and 2005, the Initial Forecast (Schedule 3) represents Celltech’s minimum commitment for the number of weeks of Manufacture of Reserved Capacity.

9.2 For the calendar years 2006 to 2010, the Initial Forecast represents a projected requirement by Celltech for each calendar year, which can be re-allocated by Celltech to other years within the Initial Forecast (Schedule 3) subject to the following conditions:

9.2.1 Celltech shall provide Lonza with at least 12 months notice of forecasted Manufacture in any year of a request to change the forecast for that year;

9.2.2 For any single year, up to 50% of the number of weeks in the Initial Forecast may be re-allocated either backward into the previous year, or forward into the subsequent year;

9.2.3 Weeks that are re-allocated pursuant to Clause 9.2.2 will become fixed and no longer subject to further re-allocation;

9.2.4 Re-allocation shall be subject to Lonza’s ability to meet the revised forecast, and shall be at Lonza’s discretion. Lonza shall use Commercially Reasonable Efforts to meet Celltech’s requirements to reallocate weeks.

9.3 The following procedure shall apply to forecasting and ordering of Batches under the Reserved Capacity:

9.3.1 By 15th July 2003, Celltech shall request a Manufacturing Start Date for the start of the Reserved Capacity for the subsequent 2 (two) years in 2004 and 2005;

17

9.3.2 By 1st September 2003, Lonza shall submit a proposed Manufacturing Start Date (together with Delivery Dates) for the start of the Reserved Capacity for 2004 and 2005, using Commercially Reasonable Efforts to meet Celltech’s requested Manufacturing Start Date;

9.3.3 Within 10 (ten) days of receipt of Lonza’a proposal, Celltech shall either agree or reject the proposal;

9.3.4 In the event that Celltech agrees to the proposal, then the Lonza Manufacturing Start and Delivery Dates for the Reserved Capacity for 2004 shall represent a Binding Order, and the Reserved Capacity in 2005 shall represent a non-binding forecast, subject to any variation agreed by the parties pursuant to Clauses 9.5 or 9.7.

9.3.5 In the event that Celltech rejects the proposal, then both parties will meet within 10 (ten) days to agree alternative dates.

9.4 In each of subsequent years 2004 to 2009, Celltech and Lonza shall agree a Manufacturing Start Date for the Reserved Capacity in years 2006 to 2010 following the same forecasting and procedure set out in Clause 9.3.

9.5 In the event that for any reason, and despite Commercially Reasonable Efforts by both parties, Lonza are unable to Manufacture Batches under the Reserved Capacity which are the subject of a Binding Order, Celltech shall have the option to cancel any or all of such Batches and Celltech shall have no liability to Lonza for the Reserved Capacity fees for such Batches.

9.6 In the event of (i) rejection pursuant to Clauses 7.6 or 8 of any Batch which has been Manufactured under the Reserved Capacity, or (ii) cancellation by Celltech pursuant to Clause 9.5 of any Batches than Lonza is unable to Manufacture, then Celltech shall have the option to re-allocate the Reserved Capacity utilised or intended to be utilised for the Manufacture of such Batch(es) to any subsequent calendar year of Manufacture under this Agreement. Lonza shall use Commercially Reasonable Efforts to meet Celltech’s requirements to re-allocate such Reserved Capacity.

9.7 At any time, Celltech and Lonza may request a change to a non-binding forecast. Both parties shall use Commercially Reasonable Efforts to meet the other’s request to change the period of Manufacture during the period to which the nonbinding forecast applies.

18

Additional Capacity

9.8 If Celltech wishes to obtain further Batches in addition to those ordered under the Reserved Capacity then, the following procedure shall apply to forecasting and ordering of such additional Batches:

9.8.1 By 15^th January 2004, Celltech shall provide a forecast for Batches to be delivered in the 24 month period beginning 1st July 2004 and ending 30^th June 2006.

9.8.2 By 15^th February 2004 Lonza shall provide a capacity forecast that will provide Out-of-Freeze, Manufacture Start Dates and Delivery Dates for Batches forecasted during Celltech’s 24 month forecast.

9.8.3 On written acceptance by Celltech of the capacity forecast provided by Lonza, the first 12 months of the 24 month forecast shall constitute a Binding Order in respect of the number of Batches and the period in which such Batches are to be Manufactured. The second 12 months of the forecast shall represent a non-binding forecast of the parties. If Celltech rejects the capacity forecast for the first 12 months of the 24 month forecast, then the parties shall meet within 10 days in an effort to attempt to agree alternative dates.

9.8.4 By 15^th July 2004, Celltech shall provide an update to the forecast for Batches for the 12 month non-binding period (1^st July 2005 to 30^th June 2006). Celltech shall also provide a forecast for Batches for a further 6 months beyond the non-binding period, in this case to cover the period beginning 1^st July 2006 to 31^st December 2006.

9.8.5 By 1^st September 2004, Lonza shall provide an update to the capacity forecast for the 12 month non-binding period (1^st July 2005 to 30 June 2006). Lonza shall also provide a capacity forecast that will provide Out-of-Freeze, Manufacture Start and Delivery Dates for Batches forecasted during Celltech’s additional 6 month forecast (1st July 2006 to 31^st December 2006).

9.8.6 On written acceptance by Celltech of the capacity forecast provided by Lonza, the first 6 months of the 12 month non-binding forecast of Clause 9.3 shall constitute a Binding Order in respect of the number of Batches and the period in which such Batches are to be Manufactured. The remaining 6 months of the non-binding period and the additional 6 months newly forecasted by Celltech in Clause 9.8 shall represent a revised 12 month period that is a non-binding forecast of the parties. If Celltech rejects the capacity forecast for the first 6 months of the 12 month forecast, then the parties shall meet within 10 days in an effort to attempt to agree alternative dates.

9.8.7 For years subsequent to 2004, Celltech and Lonza shall update the forecasting and ordering in an identical manner to Clauses 9.8.1 to 9.8.6. This means that Celltech shall, by the 15^th January and by the 15^th July of each subsequent year, provide an update to the outstanding 12 month non-binding period, plus a forecast for an additional 6 months beyond that period. Lonza shall respond to the updated forecast

19

by 15^th February and 1^st September, respectively, by providing an update to the capacity forecast for the 12 month non-binding period, plus a capacity forecast for the additional 6 months beyond that period. On written acceptance by Celltech of the revised capacity forecast provided by Lonza for Out-of-Freeze, Manufacture Start and Delivery Dates, the first 6 months of the non-binding period shall constitute a Binding Order in respect of the number of Batches and the period in which such Batches are to be Manufactured. If Celltech rejects the capacity forecast for the first 6 months of the 12 month forecast, then the parties shall meet within 10 days in an effort to attempt to agree alternative dates. The remaining 6 months of the non-binding period and the additional 6 months newly forecasted by Celltech and Lonza shall represent a revised 12 month period that is non-binding on both parties.

10. CANCELLATION

10.1 At any time, on a Batch by Batch basis, Celltech may cancel any Batches ordered under this Agreement by notice in writing to Lonza.

10.2 In the event that Celltech cancels any Batches, invoicing and payment for such cancelled Batches shall be as set forth in Clause 11.3.

10.3 Subject to Clause 2.3, in respect of Batches ordered under the Reserved Capacity which are then cancelled under Clause 10.1, the full payment for such weeks of Reserved Capacity shall be paid.

10.4 Subject to Clause 2.3, the cancellation fee for the cancellation of any additional Batches ordered pursuant to Clause 9.8 shall be as follows:

(a) * of the Batch price for cancellation notified less than 6 months prior to the Manufacturing Start Date;

(b) * of the Batch price for cancellation notified between 7-9 months from the Manufacturing Start Date;

(c) * of the Batch price for cancellation notified between 10-12 months from the Manufacturing Start Date,

The Batch price shall be agreed by good faith discussions between the parties prior to Manufacture of each Campaign of Product or in the event of failure to agree, shall be determined on the basis for calculation of the estimated Batch price for Manufacture of the Batches as set out in Schedule 1.

10.5 Where Lonza is notified of Celltech’s cancellation of a Batch or Batches and such Batch or Batches are not cancelled pursuant to Clause 2.3, then Lonza shall use Commercially Reasonable Efforts to resell the capacity previously scheduled for

20

the Celltech Batches. If Lonza is successful in selling the capacity previously scheduled for such cancelled Batches, Celltech will not be responsible for the cancellation fee for such Batch(es), however Lonza may invoice Celltech as set forth in Clause 11.3, for such cancelled Batches as follows:

(a) * of the Batch price for each cancelled Batch to cover any administration fee; and

(b) for any shortfall in revenue resulting from discounts given to secure orders for the capacity, so long as the total amount invoiced to Celltech under this Clause 10.5 is always at least * less than the amount that would have been due for the cancelled Batches if such Batches had not been resold.

11. PRICE AND PAYMENT

11.1 The fees payable by Celltech to Lonza shall be as follows, and as further set out in Schedule 1:

11.1.1 The fee payable for the weeks of Manufacture of Reserved Capacity shall be the Introductory Rate;

Celltech agrees to hold all information learned from such audits as Confidential Information, except to the extent necessary for Celltech to reveal such information in order to enforce its rights under this Agreement. The results of each audit shall be binding on both Parties. The independent auditor shall simultaneously supply both Celltech and Lonza with a copy of any report prepared as a result of such audit. Celltech shall pay for such audits, except in the event where there is a total overcharge of more than five percent (5%), in which case Lonza shall pay for such audit.

12. RAW MATERIALS AND CAPITAL ITEMS

12.1 All fees set forth in Clause 11 are exclusive of the cost of Raw Materials.

12.2 Except for those Raw Materials that Celltech agrees it will provide to Lonza, Lonza shall contract with third parties and pay (subject to Celltech’s reimbursement) for the supply of all Raw Materials necessary to Manufacture and package Product in accordance with the terms of this Agreement. Lonza shall invoice Celltech for Raw Materials in an amount equal to the cost of such Raw Materials, plus *. Such invoices shall be sent to Celltech for all Raw Materials used in the Manufacture of a Batch upon delivery of such Batch.

12.3 Lonza shall use the Raw Materials only for Manufacturing Product and will maintain written records of all purchases of Raw Materials.

12.4 Lonza shall be responsible for acceptance testing of Raw Materials to cGMP in accordance with the terms of the Quality Agreement.

12.5 Manufacture of Product may require use of Capital Items. In the event that either Lonza or Celltech identifies that such Manufacture requires use of a Capital Item, Lonza and Celltech shall agree on the specification for such Capital Item and, unless otherwise agreed, Lonza shall be responsible for ordering such Capital Item and arranging timely delivery of such Capital Item prior to commencement of the relevant Manufacture. Celltech shall pay Lonza for any such Capital Item in accordance with the payment terms set out in Clause 11.4.

12.6 Following delivery of any Capital Item to Lonza under Clause 12.5, Lonza shall store such Capital Items until used in Manufacture. If a Capital Item is not used for Manufacture of Product for 1 year, Lonza shall either (a) deliver the Capital

22

Item to Celltech, at Celltech’s cost and expense, or (b) be entitled to charge Celltech in respect of the ongoing storage requirements for such Capital Item, including the need to maintain the qualified status of the Capital Item and the length of time in storage. This fee shall be agreed in writing between the parties in respect of each such Capital Item and shall be invoiced quarterly during the currency of such storage. In the absence of agreement, Lonza shall not be obliged to undertake such storage, and shall deliver the Capital Item to Celltech at Celltech’s cost and expense.

Basis for calculation of Manufacturing Rates:

The Manufacturing Rate for the BPMSS has been calculated based on a Process in which a single fermentation plus subsequent 5 column purification takes 12 days (from inoculum to final fill of Product) and each Batch is completed 8 days after the previous Batch. In addition to the time spent on Manufacture, a further 2 weeks are added for preparation and cleaning of the plant for each Campaign for the Manufacture of each Product, which are not included in Table 2 and which will be charged separately at the same rate as Manufacture. The fee for the BPMSS will be charged on a weekly basis as shown in Table l above. On this basis, the estimated Batch price, which will vary depending on the specific Process and the number of weeks reserved, are indicated in Table 2 below.
