The report, plan and estimate provided to Celltech pursuant to this Article shall be the same standard, quality and completeness as those utilised by Amgen in its internal deliberations and decision making concerning whether to proceed with the Development of such Antibody Product in the new indication. Within [*] of receiving such notice, Celltech may again exercise its opt out right with respect to such Antibody Product by written notice to Amgen.

(c)

At the date Celltech provides its written notice to Amgen that it is exercising its opt-out right pursuant to Articles 3.4(a) or 3.4(b), as appropriate, Celltech shall provide Amgen with a document signed by an authorized officer of Celltech on its behalf either indicating in such document that (i) the written representations and warranties of Celltech set out in Articles 16.1, 16.2 and 16.3 are true and correct as if made as of the date of such document and as if referring to the Licence Agreement and not this Agreement or (ii) such written representations and warranties of Celltech are not true and correct and the reasons why such representations and warranties are not true and correct; provided that failure to provide Information that is subject to a Third Party confidentiality obligation shall not make the representation and warranty under Article 16.2(c) or 16.3(c) untrue or incorrect.


(d)	Within [*] after receipt of Celltech's written notice to Amgen under Article 3.4(c), Amgen shall provide Celltech with a document signed by an authorized officer of Amgen on its behalf either indicating in such document that (i) the written representations and warranties of Amgen set out in Articles 16.1 and 16.2 are true and correct as if made as of the date of such document

and as if referring to the Licence Agreement and not this Agreement or (ii) such written representations and warranties of Amgen are not true and correct and the reasons why such representation and warranties are not true and correct; provided that failure to provide Information that is subject to a Third Party confidentiality obligation shall not make the representation and warranty under Article 16.2(c) untrue or incorrect.

(e)

If Celltech shall not have exercised its opt-out right under Articles 3.4(a) or 3.4(b) with respect to an Antibody Product, this Agreement shall remain in full force and effect with respect to all Antibody Products. However, Celltech's opt out right shall apply to any other Antibody Product that Amgen proposes to advance or advances to Late Stage Development, and Articles 3.4(a) and (b) shall apply mutatis mutandis to all such Antibody Products.

(f)

In the event Celltech shall exercise its opt-out right pursuant to Article 3.4(a) or (b) for any Antibody Product, the Licence Agreement shall immediately come into full force and effect for such Antibody Product (as well as all Subsequent Products). This Agreement shall terminate in relation to such Antibody Product (as well as all Subsequent Products), but remain in full force and effect with respect to any Antibody Product which has previously been subject to the procedures set out in Article 3.4(a) and which Celltech shall not have previously exercised its opt-out right. If Celltech exercises its opt-out right, Celltech shall have no liability for any Research and Development Costs of Late Stage Development, whether or not incurred prior to expiry of the opt-out period.

3.5

Budgets. The budgets for each Contract Year during Research and Development shall be specified by each Party and submitted to the other Party (via the Joint Research Committee or Joint Development Committee, respectively) in a format to be agreed by the Parties but which must include line item estimates of Research and Development Costs by function. The budgets shall be updated by the Joint Research Committee or Joint Development Committee (as appropriate) at least once annually on a timeline that meets the budget planning requirements of both Parties, but in no event less than [*] before the end of the preceding Contract Year; provided however, it is acknowledged and agreed that such budgets may need to be modified from time-to-time between annual updates, based upon the results of clinical studies and other unanticipated events. In any Contract Year, each Party shall promptly inform the other Party upon such Party determining that it is likely to exceed or underspend by more than [*] ([*]%) its respective total budget in that Contract Year. In addition, if in any Contract Year a Party exceeds its budget by more than [*]%, the Party who has so exceeded its budget shall, at the request of the other Party, provide to the Joint Research Committee or Joint Development

Committee (as appropriate) and to the Collaboration Committee (if the matter is escalated to the Collaboration Committee) a full explanation for exceeding its budget (as requested). Each Committee may, [*], reduce the amount of any overspend to be included in the Research and Development Costs as it considers equitable in the circumstances. If either the Joint Research Committee or Joint Development Committee do not [*] on how to deal with such overspend, the matter shall be escalated to the Collaboration Committee for consideration. The members of any such Committee (as appropriate) may elect to reduce or not reduce such overspend [*], and unless the relevant Committee [*] to reduce the overspend, [*].


3.6	Costs. Amgen and Celltech shall share all costs for the Research and Development of Antibody Products on the following basis:


3.6.1	Research Costs

Other than as provided below with respect to amounts paid to Third Parties, Celltech and Amgen shall each bear its own Research and Development Costs in carrying out its Research activities. The cost of supplying Amgen with Antibodies for Research shall be considered as Research and Development Costs to be borne by Celltech. All out-of-pocket Research and Development Costs paid to Third Parties shall be paid to any such Third Parties by the Party engaging the services of such Third Parties and, as between Amgen and Celltech, shall be shared on the basis of [*]:[*] Amgen: Celltech. Such Third Party costs shall include the cost of supply of GMP Antibody for Research by a Third Party on behalf of Celltech as required by Amgen for the purposes of pre-clinical or formulation studies.


3.6.2	Early Stage Development Costs

All Research and Development Costs cumulatively incurred (whether FTE Cost incurred directly by Amgen or Celltech or amounts payable to Third Parties engaged by Celltech or Amgen) for Early Stage Development of Antibody Products shall be shared, as follows:


(a)	up to [] Dollars ($[]) of such cumulative Research and Development Costs, on the basis of []:[] Amgen:Celltech;


(b)	over [] Dollars ($[]) of such cumulative Research and Development Costs on the basis of []:[] Amgen:Celltech.

6.4

Third Party Manufacturers. Celltech shall not enter into any Supply Agreement with a Third Party for Antibody Raw Material as specified in this Article 6 without first obtaining the consent of Amgen to such agreement (such consent not to be unreasonably withheld or delayed). Celltech shall use Commercially Reasonable Efforts to ensure that, in addition to the terms set forth in Articles 6.2 and 6.3 (as appropriate), such Supply Agreement shall contain terms that, in the event that either Celltech or Amgen assumes exclusive responsibility for manufacture and supply of Antibody Raw Material pursuant to Article 6.7, will grant Celltech the right to (a) terminate such agreement on reasonable notice with respect to Antibody Raw Materials, (b) have transferred to Amgen or Celltech (as appropriate) and to receive assistance reasonably required by Amgen or Celltech (as appropriate) to effect transfer of the Third Party's Information relating to the manufacture and analysis of Antibody Raw Material in sufficient detail for Amgen or Celltech (as appropriate) to implement the [*] of such[*], including Information contained in the [*] of any applicable Regulatory Filings and the results of any stability studies performed on Antibody Raw Material, (c) have provided Amgen or Celltech (as appropriate) such Information pertaining to the manufacture and analysis of Antibody Raw Material as Amgen or Celltech (as appropriate) shall reasonably request; (d) if requested by Amgen or Celltech (as appropriate), obtain reasonable assistance in the manufacture of trial batches of Antibody Raw Material to enable Amgen or Celltech (as appropriate) to determine its ability to manufacture Antibody Raw Material; (e) audit in accordance with Article 6.6; (f) obtain copies of any direct communications by or to the Manufacturing Lead from Regulatory Authorities having jurisdiction in the Territory regarding and concerning the manufacture of any Antibody Product and (g) name Amgen as a permitted assignee or sublicensee.

Once Amgen has given such consent, Amgen shall be deemed to have accepted the terms of such Third Party Supply Agreement. Both Parties shall comply and operate in accordance with the terms of any such Supply Agreement accepted by Amgen and entered into by Celltech. To the extent the

same relates to Antibody Product, all (i) out-of-pocket costs, expenses and liabilities (calculated on an arm's-length basis in accordance with GAAP), (ii) FTE Cost and (iii) cost of Materials used, which are incurred by Celltech in discharging its obligations pursuant to this Article 6 shall be Research and Development Costs if incurred for Development and a Commercialisation Expense if incurred for Commercialisation, and all amounts recovered from any Third Party supplier shall be credited to Product Contribution revenues, provided however, that if the costs, liabilities and/or amounts recovered are also applicable to products other than Antibody Products, then only an equitable portion of such costs, liabilities and/or amounts recovered shall be so allocated. The sharing of liabilities under any Third Party Supply Agreement is without prejudice to Article 18. In the event that Amgen obtains supply of Antibody Product in Finished Form from a Third Party, costs, liabilities and/or amounts recovered shall also be allocated to Research and Development Costs or Commercialisation Expenses mutatis mutandis.


6.5	Standards of Supply. Antibody Raw Material, in the case of the Manufacturing Lead, and Antibody Products in Finished Form, in the case of Amgen, shall be manufactured in accordance with current GMP in manufacturing processes and facilities as described in the applicable Regulatory Filings submitted to and approved by the Regulatory Authority.

Each Party, to the extent it is not the Manufacturing Lead, shall have the right to conduct reasonable quality assurance audits with respect to all facilities, operations and laboratories (and any records related thereto) of the other Party or its subcontractors (provided that, where the Manufacturing Lead is a Third Party, only to the extent permitted by the relevant Supply Agreement), where applicable manufacturing activities are conducted, as is reasonably necessary to verify the Manufacturing Lead's conformance (or Amgen's conformance with respect to Antibody Product in Finished Form) with cGMP, cGLP, cGCP and other regulatory requirements. Such audits shall be conducted upon reasonable notice during reasonable business hours.


6.7	Manufacturing Option.

(a)

At any time during Development or Commercialisation and subject to any commitments already made to any Third Party supplier either Party may seek to manufacture and supply Antibody Raw Material by providing written notice to the other Party and the Collaboration Committee that it wishes to assume manufacture and supply of the Antibody Raw Material for the Territory or its Lead Territory. Within [*] after receipt of such request, the other Party

shall have the right to provide reciprocal notice of its desire to manufacture and supply Antibody Raw Material.

Thereafter, the Collaboration Committee shall promptly meet to consider any and all requests and determine ([*]) whether one or both of the Parties should have the right and obligation to manufacture and supply Antibody Raw Material, applying the following criteria:


(i)	the FAMC resulting from the requesting Party's manufacturing is likely to be less than the actual or probable FAMC as invoiced by the Third Party manufacturer or, if both Parties desire to assume such responsibility, the probable FAMC as between the Parties;


(ii)	other benefits, such as stability of supply or quality of product, are like to accrue to both Parties as a result of manufacture of Antibody Raw Material by the requesting Party or Parties;


(iii)	a Third Party manufacturer for Development or Commercialisation supplies has not been identified or such Third Party manufacturer is unable or unwilling to enter into a Supply Agreement on terms reasonably satisfactory to both Parties;


(iv)	the desirability of a second (or further) source of supply of Antibody Raw Material;


(v)	that the Third Party manufacturer is in material breach of its supplier obligations and that as a result of such breach, the requesting Party or Parties should assume manufacture and supply of Antibody Raw Material; or


(vi)	the cost and difficulty of enforcing the relevant Supply Agreement to enable one or both Parties to manufacture and supply Antibody Product.

(b)

If the Collaboration Committee determines that, after applying the foregoing criteria, in total it would be beneficial to the interests of both Parties that the requesting Party or Parties manufacture and supply Antibody Raw Material, the selected Party or Parties shall have the right and obligation to manufacture and supply Antibody Raw Material for either the Territory or its Lead Territory as determined by the Collaboration Committee. Upon selection of a Party, then


(i)	If Amgen is the selected Party, Celltech shall itself transfer any Information Controlled by Celltech, and Celltech shall use the level of effort determined by the Collaboration Committee to enforce (or, at the request of Amgen and to the extent permitted by the

terms of the Supply Agreement assign to Amgen the right to enforce) the terms and conditions of the Third Party Supply Agreement entered into by Celltech pursuant to Article 6.4 including (but only to the extent permitted by the Supply Agreement with such Third Party) the provision to Amgen of any Information and assistance reasonably required by Amgen from such Third Party pertaining to the manufacture and analysis of Antibody Raw Material with the objective of Amgen being enabled to implement the [*] of [*], including Information contained in the [*] of any applicable Regulatory Filings and the results of any stability studies performed by or on behalf of Celltech; and

(ii)

If Amgen is the selected Party, Celltech shall, at the request of Amgen, use the level of effort determined by the Collaboration Committee to enforce (or, to the extent permitted by the Supply Agreement with such Third Party assign to Amgen the right to enforce) the terms and conditions of the Third Party Supply Agreement entered into by Celltech pursuant to Article 6.4 (but only to the extent such terms are included in any such Supply Agreement, and only to the extent such Supply Agreement relates to Antibody Raw Material) including termination of the Third Party Supply Agreement on reasonable notice (but only if the Collaboration Committee has determined Amgen shall have the exclusive right and obligation to manufacture and supply Antibody Raw Material); and


(iii)	The Parties (as appropriate) shall continue to work with the Third Party supplier in order to achieve the manufacturing transition or second sourcing with minimal disruption, and to ensure adequate supplies of Antibody Raw Material during the transitional process; and


(iv)	The Party or Parties assuming the obligation to manufacture and supply Antibody Raw Material Party shall use Commercially Reasonable Efforts to put all necessary manufacturing processes in place so as to be able to meet Development or Commercialisation requirements (as appropriate) of Antibody Raw Material (of a quality and quantity required of the Manufacturing Lead); and


(v)	The Party assuming the obligation to manufacture and supply Antibody Raw Material shall have the right to include the cost of [*] as Research and Development Costs if such transfer takes place during Development or as a Commercialisation Expense if

such transfer takes place during Commercialisation (but only to the extent any such costs relate to Antibody Raw Material).

(c)

All amounts paid to the Third Party in connection with the supply of Antibody Raw Material and any Third Party Supply Agreement (including all amounts paid in connection with the provision of Information and assistance), and all costs incurred by the Parties in enforcing the terms of any Supply Agreement, shall be a Research and Development Cost if incurred for Development and a Commercialisation Expense if incurred for Commercialisation. All amounts recovered from the Third Party by way of damages as a result of any breach by the Third Party supplier in the supply of Antibody Raw Material shall be revenues included in the calculation of the Product Contribution.

6.8

Quality Responsibility. The Parties acknowledge that, in order to meet regulatory requirements prior to the commencement of any supply of Antibody Raw Material or Antibody Product in Finished Form, appropriate quality assurance agreements relating to such supply must be entered into between the Parties and between each Party and its Third Party manufacturers. The Parties will negotiate such quality assurance agreements in good faith having regard to the document entitled “Quality Responsibilities” and dated March 12, 2002. If the Parties are unable to conclude any such agreement then the matter shall be referred at the request of either Party to the Collaboration Committee.

(b)

Net Sales or other revenues received or payments due in currencies other than Dollars shall first be calculated in the relevant foreign currency and then converted to Dollars against the currency in question on the rate of exchange applicable on the last Business Day of the Calendar Quarter in respect of which the funds are payable using the currency exchange rates quoted by Bloomberg Professional, a service of Bloomberg L.P., during the period of such Net Sales, or in the event Bloomberg Professional is not available then The Wall Street Journal. Budgets and intra-budget forecasts of future Net Sales and expenses in currencies other than Dollars shall be converted into Dollars at budget rates to be agreed between the Parties at the Joint Commercialisation Committee.

(c)

All amounts due under this Agreement shall be paid exclusive of any Value Added Tax (which, if applicable shall be payable by a Party in addition upon receipt of a valid Value Added Tax invoice). Each Party agrees to inform the other Party forthwith if it concludes that there is a Value Added Tax law or practice, or a change in such law or practice, which requires it to account for Value Added Tax on any payments due pursuant to this Agreement at any time after the Effective Date, with a view to the Parties using their best endeavours to agree on the manner in which subsequent payments shall be made to reduce or eliminate the liability of the Parties to pay Value Added Tax.

(d)

All amounts due under this Agreement shall be paid in full without deduction for any applicable taxes, levies, imposts, duties and fees of whatever nature imposed by or under the authority of any government or public authority, except for tax legally required to be deducted or withheld.

Each Party and their respective Affiliates shall permit independent accountants of internationally recognised standing retained by the other Party (the “Auditing Party”) and reasonably acceptable to the other Party, upon reasonable prior written notice, to have access to its and its Affiliates' records and books and premises for the sole purpose of determining the appropriateness of costs charged by or accrued to the Party being audited and the correctness of amounts due and payable under this Agreement for any year ending no more than [*] prior to the date of such request; provided however, that the books and records for any particular Contract Year shall only be subject to one audit. Such examination shall be conducted during regular business hours and no more than once in each calendar year. The report of such accountant shall be limited to a certificate verifying, or not verifying, as the case may be, any report made or payment submitted by the audited Party during such period. In the event the accountant shall be unable to verify the correctness of any such

payment, the accountant's report shall specify why such payment is unverifiable and the amount of any discrepancy. The audited Party shall receive a copy of each such report concurrently with receipt by the Auditing Party and the Parties shall use good faith efforts to resolve any discrepancies. All information contained in any such report shall be deemed Confidential Information hereunder. If such examination reveals that such costs or payments have been misstated, any adjustment shall be promptly refunded or paid, as appropriate. The Auditing Party shall pay the fees and expenses of the accountant engaged to perform the audit, unless such audit reveals a net discrepancy of [*] ([*]%) or more for the period examined which is to the disadvantage of the Auditing Party, in which case the Party who misreported shall pay all reasonable costs and expenses incurred by the Auditing Party in the course of making such determination. Upon the expiration of [*] following the end of any Contract Year, the calculation of any such amounts payable with respect to such year shall be binding and conclusive upon a Party entitled to such audit and the other Party or its Affiliates shall be released from any liability or accountability with respect to such amounts for such year.

12.4 Terms of Agreement.

Except as permitted by the foregoing provisions or as otherwise required by law or the rules of any relevant stock exchange or the U.S. Securities and Exchange Commission, the Parties shall not disclose any terms or conditions of this Agreement to any Third Party without the prior consent of the other Party; provided however, that each Party shall be entitled to disclose the terms of this Agreement without such consent on a need-to-know basis to its financial and legal advisors and potential investors or other financing sources on the condition that such entities or persons agree to keep such terms confidential for the same time periods and to the same extent as such Party is required to keep such terms confidential. Each Party shall give the other Party a reasonable opportunity to review all filings with the United States Securities and Exchange Commission or any stock exchange describing the terms of this Agreement prior to submission of such filings, and shall give due consideration to any reasonable comments by the non-filing Party relating to such filing, including the provisions of this Agreement for which confidential treatment should be sought.

12.5

Public Announcements. Following the Effective Date, the Parties shall issue one or more press releases regarding this Agreement, the timing and content of which shall be mutually agreed. Except to the extent required by law or the rules of a relevant stock exchange or as otherwise permitted in accordance with this Article 12, neither Party shall make any further public announcements concerning this Agreement or the subject matter hereof without the prior written consent of the other, which shall not be unreasonably withheld or delayed.

12.7

Third Party Obligations. Other than with respect to Article 16.4(e), neither Party is obliged to disclose to the other any Information if to do so would put the disclosing Party in breach of an existing or future obligation owed to a Third Party. Without limitation to the foregoing, Amgen acknowledges that Celltech is not obliged to disclose to Amgen, and will not disclose to Amgen, any Information, data or know-how concerning Celltech's products [*] whether arising out of Celltech's [*] or otherwise.

ARTICLE 13

PUBLICATIONS

13.1

Procedure. The Collaboration Committee (or its appropriate designees) shall determine the strategy for and co-ordinate the publication and presentation of results of studies of Antibody Products or which incorporates data generated under this Agreement. Each Party to this Agreement recognises that the publication of papers regarding results of and other information regarding activities under this Agreement, including oral presentations and abstracts, may be beneficial to both Parties provided such publications are subject to reasonable controls to protect Confidential Information. In particular, it is the intent of the Parties to maintain the confidentiality of any Confidential Information included in any patent application until such patent application has been published. Accordingly, each Party will have the right to review and approve any paper proposed for publication by the other Party, including oral presentations and abstracts, which incorporates data generated under this Agreement

and/or includes Confidential Information of the other Party. Before any such paper is submitted for publication or an oral presentation is made, the publishing or presenting Party will deliver a complete copy of the paper or materials for oral presentation to the other Party at least [*] prior to submitting the paper to a publisher or making the presentation. The other Party will review any such paper and give its comments to the publishing Party within [*] of the delivery of such paper to the other Party. With respect to oral presentation materials and abstracts, the other Party will make reasonable efforts to expedite review of such materials and abstracts, and will return such items as soon as practicable to the publishing or presenting Party with appropriate comments, if any, but in no event later than [*] from the date of delivery to the other Party. Failure to respond within such [*] shall be deemed approval to publish or present. If approval is not given or deemed given, for publications or presentations of other than Marketing Clinical Studies, the matter shall be referred to the Collaboration Committee together with the reasons for withholding approval. Publications or presentations to the extent relating to Marketing Clinical Studies shall be determined by the Territorial Commercial Lead that conducted such Marketing Clinical Studies, having considered the comments of the other Party. Notwithstanding the foregoing, the publishing or presenting Party will comply with the other Party's request to delete references to the other Party's Confidential Information in any such paper and, with respect to Marketing Clinical Studies, will withhold publication of any such paper or any presentation of same for an additional [*] in order to permit the Parties to obtain patent protection, if either of the Parties deems it necessary, in accordance with the terms of this Agreement.


13.2	Credit. Any such publication will include recognition of the contributions of the other Party according to standard practice for assigning scientific credit, either through authorship or acknowledgement, as may be appropriate.

ARTICLE 14

TERM AND TERMINATION


14.1	Term. This Agreement shall become effective on the Effective Date and shall remain in full force and effect, unless earlier terminated pursuant to Article 3.4 or this Article 14, for such time as the Antibody Products are being Researched, Developed or Commercialised by the Parties.

14.4 Termination for Default.

(a)

In the event any material representation or warranty made hereunder by either Party shall have been untrue in any material respect and this has had a material and adverse effect on the other Party in relation to this Agreement (“Representation Default”), or upon any material breach or material default of a material obligation of this Agreement by a Party (“Performance Default”), the Party not in default (“Non-Defaulting Party”) must first give the other Party (“Defaulting Party”) written notice thereof (“Notice of Default”), which notice must state

the nature of the Representation Default or Performance Default in reasonable detail and must request the Defaulting Party cure such Representation Default or Performance Default within [*], or if such Default cannot be cured, take such action as will substantially mitigate the material adverse effect of such Default on the other Party. During any such [*] period after receipt or delivery of a Notice of Default under this Article 14.4(a) for which termination of this Agreement is a remedy, all of each Party's respective rights and obligations under this Agreement, including Research, Development, and Commercialisation, shall (to the extent applicable) remain in force and effect. If the Defaulting Party shall dispute the existence, extent or nature of any default set forth in a Notice of Default, the Parties shall use good faith efforts to resolve the dispute.


(b)	In the event of a Representation Default or a Performance Default by Celltech that shall not have been cured or mitigated within the [*], as set forth in Article 14.4(a) above, Amgen, at its option, may immediately terminate this Agreement upon prior written notice to Celltech. Termination shall be effective upon the receipt of such notice by Celltech.


(c)	In the event of a Representation Default or a Performance Default by Amgen that shall not have been cured or mitigated within the [*], as set forth in Article 14.4(a) above, Celltech, at its option, may immediately terminate this Agreement upon prior written notice to Amgen. Termination shall be effective upon the receipt of such notice by Amgen.

14.5 Bankruptcy.

(a)

All rights and licences granted under or pursuant to this Agreement by Amgen or Celltech are, and shall otherwise be deemed to be licences of rights to “intellectual property”. The Parties agree that the Continuing Party (as defined below) shall retain and may fully exercise all of its rights and elections under bankruptcy legislation in the Territory. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a bankrupt Party the other Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property which at that date is known to be necessary or useful to an Antibody Product (then the subject of Research or Development or Commercialisation) and all embodiments of such intellectual property; and same, if not already in the other Party's possession, shall be promptly delivered to the other Party (a) upon any such commencement of a bankruptcy proceeding, upon the other Party's written request therefor (which request must identify the specific intellectual property), unless the non-

bankrupt Party (or a trustee on behalf of the bankrupt Party) elects within [*] to continue to perform all of its obligations under this Agreement or (b) if not delivered under (a) above, upon the rejection of this Agreement by or on behalf of the bankrupt Party, upon written request therefor by the other Party.

(b)

Without prejudice to Article 14.5(a) this Agreement may be terminated by a Party upon prior written notice to the other in the event that (i) the other Party shall make an assignment for the benefit of its creditors, file a petition in bankruptcy, petition or apply to any tribunal for the appointment of custodian, receiver or any trustee for it or a substantial part of its assets, or shall commence any proceeding under any bankruptcy, reorganisation, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction (other than for the purposes of a solvent amalgamation or reconstruction), whether now or hereafter in effect; or (ii) if there shall have been filed against the other Party any such bona fide petition or application, or any such proceeding shall have been commenced against it, in which an order for relief is entered or which remains undismissed for a period of ninety (90) days or more; or (iii) if the other Party by any act or omission shall indicate its consent to, approval of or acquiescence in any such petition, application or proceeding or order for relief or the appointment of a custodian, receiver or trustee for it or any substantial part of its assets, and shall suffer any such custodianship, receivership or trusteeship to continue undischarged for a period of ninety (90) days or more (each an “Insolvency Event”). Termination shall be effective upon the date specified in such notice. Notwithstanding the foregoing, this Agreement shall not be terminated pursuant to this Article 14.5(b) if, prior to the effective date of termination stated in the written notice from the Party desiring to terminate this Agreement, the Party experiencing the Insolvency Event demonstrates to the other Party that it is not insolvent.

14.6

Additional Termination Right of Celltech. If in any suit or proceeding where Celltech or any of its Affiliates is a named party Amgen or any of its Affiliates asserts, or Amgen or any of its Affiliates provides Confidential Information, financial assistance or technical assistance in collusion with a Third Party to assist such Third Party in asserting that any claim within the [*] Patent Rights or any [*] Patent Rights is invalid, Celltech, at its option, may, within [*] of such assertion, terminate this Agreement upon [*] prior written notice to Amgen (with termination being effective upon expiry of the [*] notice period); provided however, that nothing contained herein shall prohibit Amgen or any of its Affiliates from asserting the invalidity of any claim within the [*] Patent Rights or any [*]

Patent Rights, where such assertion is raised as a defence against an assertion of such [*] Patent Rights or [*] Patent Rights in such suit or proceeding brought against Amgen or any of its Affiliates or any of its licensees (provided that such suit or proceeding relates to the licensed subject matter) or its intellectual property rights. If the inclusion of this Article 14.6 would make invalid or unenforceable any other provision of this Agreement, or any of the Patent Rights licensed pursuant to this Agreement, this Article 14.6 shall be automatically and without notice severed from this Agreement and the remaining provisions of this Agreement shall remain in force.


14.7	Opt-Out by Celltech. In the event Celltech shall provide notice of its election to opt-out of this Agreement pursuant to Article 3.4, this Agreement shall automatically terminate in accordance with that Article 3.4.

In the event a Party becomes aware of a claim which, if resulting in a Joint Loss, it intends to charge to the Product Contribution account, such Party shall inform the other Party of such claim as soon as reasonably practicable after it receives notice thereof.

Each Party shall diligently pursue recovery of insurance proceeds when a claim arises.

SCHEDULE A

Research Plan

The primary objective of the Research Plan is the [*] that has suitable [*] attributes to designate it as a clinical development candidate. To accomplish this, there will be [*] major [*] work streams. The objective of the [*] workstream is to identify [*] that will be used to validate the [*], the [*] representing the most likely initial [*] for the corresponding [*]. The work includes, but may not be limited to, characterizing [*] in a number of [*] and [*] and then [*] of [*] to identify [*]. A reasonable number of [*] will then be profiled in both [*] and [*]. It is recognised that aspects of this program are iterative by their very nature and that revisions to plan may need to occur based on experimental results. This phase would be considered successful if a [*] proved to be [*].

In parallel with this [*], a [*] workstream will be engaged around generating [*] suitable for clinical testing. Similar to the activities above, [*] will be characterized in a number of [*] and then by [*] of [*] to identify [*]. The [*] will serve as the basis for the generation of [*] which at the present time are envisioned to represent the [*]. The choice of [*], as opposed to a [*], as a clinical candidate will be decided based on the properties of the [*] and also on background data provided by [*] on clinical experience with these [*], especially their [*]. As the [*] are converted to [*], the [*] of the newly generated [*] will be tested against appropriate [*] and [*]. The selection of the [*] candidate will be based on a number of criteria. At the end of this workstream, sufficient material to initiate [*] and perform [*] will be produced. It is recognised that [*] of the [*] workstream would interrupt this plan. In that case, an alternative research plan would be identified through discussions at the Joint Research Committee.

In the event that the [*] workstreams are successful and a clinical candidate is put forward, a [*] program will be engaged to identify additional clinical candidates should the first [*] for any reason. Additionally, it is recognised that additional work directed against understanding the [*] will take place. Such activities could include [*] studies, [*] identification and so forth.

On selection of a clinical candidate, [*] will start work on development of a suitable [*] for both [*] studies and ultimately for clinical evaluation. [*] will expect advice from [*] on the [*] of such a [*] based on [*]'s previous experience with such products. [*] will need sufficient quantities of [*] to enable it to start such studies. A preliminary estimate is [*] for these [*] studies. [*] will expect this material to be supplied by [*]

108

according to a timeline that will be agreed at the Joint Research Committee. Similarly, [*] will require suitable quantities of [*] to enable it to conduct [*] studies. The time line for this will also be agreed by the Joint Research Committee.

The initial work plan, which shall be agreed by the Joint Research Committee at their first meeting, is as follows:

2.	When allocating costs and expenses under this Agreement, each Party shall utilise the same policies and principles as it utilises consistently within its group and business units when making internal cost allocations.

Each Party shall bear its own out-of pocket costs (without limitation, travel costs, meals and accommodation) associated with attendance at meetings of the Joint Research Committee, Joint Development Committee, Joint Commercialisation Committee, Collaboration Committee or such other joint meetings that the Parties agree shall be held in the furtherance of the Research, Development or Commercialisation of Antibody Products.

To the extent an item of income or revenue is received by a Party or a cost or expense is incurred by a Party, and is necessary and specifically and directly identifiable, attributable and allocable to the Commercialisation of Antibody Product and is not otherwise accounted for in the calculation of Product Contribution, such Party shall credit such income or revenue and shall be permitted to charge such cost or expense to the Product Contribution.

114

SCHEDULE C

Principles for Detail Cost

Each Party shall determine the Sales Force Costs for each Calendar Quarter for each sales force Detailing Antibody Products.

Each Party shall undertake to promote Antibody Product as a Primary Detail, Secondary Detail or Tertiary Detail throughout a Calendar Quarter.

The Detail Cost for each sales force in each country for each Party for each Calendar Quarter shall be calculated by multiplying the Sales Force Costs for that sales force in that country by [*]% when Antibody Product has been promoted as Primary Detail in that Calendar Quarter, and by [*]% when Antibody Product has been promoted as Secondary Detail in that Calendar Quarter and [*]% where Antibody Product has been promoted as Tertiary Detail in that Calendar Quarter, provided that a Party may not charge for a Tertiary Detail for Antibody Product in a country during the [*] following the date of First Commercial Sale of such Antibody Product in a country. For a period not to exceed [*] from the date of First Commercial Sale of an Antibody Product in any country and when a sales force has promoted only an Antibody Product and no other product in a Calendar Quarter in that country, the Detail Cost shall be [*]% of the Sales Force Cost, excluding extraordinary bonuses and the like.

115

SCHEDULE D

Net Sales Definition

Net Sales means with respect to any Antibody Product, all revenues recognised in accordance with GAAP, consistently applied as between the Parties, from sales of an Antibody Product by a Party, its Affiliate, sublicensees, and agents, to Third Parties (but not including sales relating to transactions between a Party, its Affiliates, and their respective sublicensees and agents), less the total of the following (if not already deducted in the amount invoiced or not otherwise accounted for in Commercialisation Expenses or Cost of Goods):


1.	Normal or customary trade, cash, prompt payment and/or quantity discounts actually allowed and taken;


2.	Returns, allowances, free goods, rebates, chargebacks, other allowances or payments to government agencies actually allowed and taken;


3.	Retroactive price reductions applicable to sales of such product actually allowed and taken;


4.	Fees paid to distributors, selling agents (excluding any sales representatives of a Party or any of its Affiliates), group purchasing organisations and managed care entities;


5.	Credits or allowances (actively paid or allowed) for wastage replacement, whether cash or trade;


6.	Non-recoverable sales taxes, excise taxes, tariffs and duties (excluding taxes when assessed on income derived from sales); and


7.	[*] percent of the amount invoiced to cover bad debt, freight or other transportation charges, insurance charges, additional special packaging, and other governmental charges.

In the case of any sale of an Antibody Product between or among a Party and its Affiliates or sublicensees for resale, Net Sales shall be calculated as above only on the first arm's length sale by any such Party, Affiliate or sublicensee to a Third Party.

Upon any sale or other disposal of any Antibody Product for any consideration other than an exclusively monetary consideration on bona fide arm's length terms then for the purposes of calculating the Net Sales under this Agreement, such Antibody Product shall be deemed to be sold exclusively for money at the average sales price during the applicable reporting period generally achieved for such Antibody Product in the country

116

in which such sale or other disposal occurred when such Antibody Product is sold alone and not with other products.

Where an Antibody Product is sold together with other pharmaceutical products for a single price (whether sold together in the same package, or merely price bundled), then for the purposes of calculating the Product Contribution payable under this Agreement such Antibody Product shall be deemed sold for an amount equal to the following:

(X divided by Y) multiplied by Z

where X is the average sales price during the applicable reporting period generally achieved for such Antibody Product in the country in which such sale or other disposal occurred when such Antibody Product is sold alone and not with other pharmaceutical products; Y is the sum of the average sales price during the applicable reporting period generally achieved in that country when sold alone by each product (including the Antibody Product) included in the bundle of pharmaceutical products that is sold for the single price; and Z equals the single price at which the bundle of pharmaceutical products represented in Y was actually sold. In the event one or more of the products in the bundled product are not sold separately, the parties shall confer in good faith to determine a fair market price that shall equitably compensate the Product Contribution for the value of the Antibody Product(s) within the bundled product.

117

SCHEDULE E

For the avoidance of doubt, Development and Commercialisation in each instance includes the manufacture and supply of Licensed Antibody Product. If Amgen decides that deployment of Commercially Reasonable Efforts does not justify it making continued, ongoing efforts towards this objective it shall promptly notify Celltech in writing.

3.1.3

Amgen shall not be in breach of any obligation under this Licence Agreement to the extent its inability to perform such obligation is caused by Celltech's failure to perform any of its obligations under this Licence Agreement or under Article 14.9 of the Collaboration Agreement. Celltech acknowledges that in applying the Commercially Reasonable Efforts standard to Amgen's obligation pursuant to Article 3.1.1, a relevant factor to be taken into account shall be [*].


3.1.4	Amgen acknowledges that the obligations it undertakes pursuant to this Article 3.1 are [*].

(ii)	Amgen having brought a suit or action described in Article 5.3.1, ceases to progress it and Celltech then requests Amgen in writing to progress such suit or action;

and Amgen elects, at its option, (or is deemed to have so elected by failing to respond to Celltech's written notice pursuant to Article 5.3.2 or within [*] of Celltech's written request pursuant to Article 4.7(a)(ii)) that Celltech shall not have the right to bring any such suit or action, then the Royalty reduction to which Amgen is entitled under Article 4.6 (the “Royalty Reduction”) shall not apply with respect to that Competitive Product in that country for the period from the date of expiry of the relevant time frame under (i) above or the date Amgen ceases to progress such suit or action under (ii) above, as appropriate.


(b)	If Celltech provides a written request pursuant to Article 5.3.2 or Article 4.7(a)(ii) and Amgen, within the time frame for bringing suit in accordance with Article 5.3.2 (or within [*] of Celltech's written request pursuant to Article 4.7(a)(ii)), provides Celltech with written notice of Amgen's election, at its option, that Celltech shall have the right to bring any suit or action

described in Article 5.3.2, then the Royalty Reduction shall not apply for the period commencing on the date of Celltech's written notice and ending [*] after the date Amgen notifies Celltech in writing of Amgen's election that Celltech shall have such right to bring such suit or action with respect to such Competitive Product in such country.

(c)

If Celltech provides a written request pursuant to Article 5.3.2 or Article 4.7(a)(ii) and Amgen, within the time frame for bringing suit in accordance with Article 5.3.2, or within [*] of Celltech's written request pursuant to Article 4.7(a)(ii), elects, at its option (as notified to Celltech in writing), that Celltech shall have the right to bring any suit or action described in Article 5.3.2 and


(i)	Celltech exercises such right; and


(ii)	the court concludes that Celltech has been prejudiced in obtaining a preliminary injunction by the delay from Celltech's written request to the date of Amgen's election to allow Celltech to exercise such right, or by Amgen failing to progress such action, then

the Royalty Reduction shall not apply and Amgen shall pay Celltech all Royalties Celltech would otherwise have been entitled to receive plus interest (at the rate provided in Article 6.1(d)) on such sum for the period from the later of Celltech's written request or the date of first commercial sale of such Competitive Product in such country up to the date of the final court decision, such sum plus interest to be paid within [*] of such final court decision.


(d)	From such time as a Competitive Product is ordered to be withdrawn from sale or otherwise ceases to be sold as a result of any suit or action brought by Celltech or by Amgen, the Royalty Reduction set forth in Article 4.6 shall not apply.

In the event it elects such defence or enforcement action, Amgen shall determine the strategy.

5.4

Infringement Defence. Amgen, at its own expense, shall subject to prior consultation with Celltech where Celltech is a named party, have the first right to defend any actual, alleged or threatened claim or action in the Territory which names Amgen and/or Amgen and Celltech and which claims (a) the infringement of Third Party Patent Rights or know-how through Researching, Developing, Commercialising, making, having made, using, selling, having sold, offering to sell or resell, importing, exporting, distributing or otherwise transferring physical possession of or otherwise transferring title in or to a Licensed Antibody Product or (b) that any Product Trademark infringes any Third Party Trademark or its use constitutes any unfair trade practice, trade dress imitation, passing off of counterfeit goods or like offence. If Amgen shall decide not to defend such an action, Celltech (to the extent it is named) may, at its own expense, defend any such claim or action. The Party defending such claim or action shall have the right, subject to prior consultation with the other Party where both Parties are named, to determine the strategy and to exclusively control the conduct and all aspects of any such proceedings; provided however that the Party defending such claim or action shall not settle or compromise such proceedings that affect the other Party's rights or interests, without the prior written consent of the other Party (which consent shall not be unreasonably withheld or delayed). When named, the Party not defending such claim or action shall be entitled, at its own expense, to participate in and to have counsel selected by it participate in any action in which the other Party is a named party.


5.5	Patent Marking. To the extent practical, Amgen will ▇▇▇▇ the Licensed Antibody Product(s) sold in its Territory with all applicable patent numbers of Patent Rights of Celltech to the extent permitted by law in the Territory in which such markings have notice value as against infringers of patents.

PAYMENTS; RECORDS; AUDIT

6.1 Payments.

(a)

No later than [*] after the conclusion of each Calendar Quarter after First Commercial Sale of a Licensed Antibody Product in each country and extending until the Calendar Quarter during which Amgen's obligation to pay Royalties for all Licensed Antibody Product(s) expires under Article 4.8, Amgen shall submit to Celltech a report setting forth (i) the Net Sales of each Licensed Antibody Product sold by Amgen, and its Affiliates and/or Sublicensees during the previous Calendar Quarter [*]; (ii) any Third Party royalties payable in respect of such Net Sales ([*]) and (iii) the amount of Royalty due hereunder. The report shall be accompanied by a remittance of the corresponding Royalty payment.


(b)	All payments to be made under this Licence Agreement shall be made in U.S. Dollars by bank wire transfer in immediately available funds to a bank account designated from time to time in writing by Celltech.


(c)	Net Sales or other revenues received or payments due in currencies other than Dollars shall first be calculated in the relevant foreign currency and then converted to Dollars against the currency in question on the rate of exchange applicable on the last Business Day of the Calendar

Quarter in respect of which the funds are payable using the currency exchange rates quoted by Bloomberg Professional, a service of Bloomberg L.P., during the period of such Net Sales, or in the event Bloomberg Professional is not available then The Wall Street Journal.


(d)	Any payment of any amount under this Licence Agreement not received by the due date specified herein shall accrue interest thereafter on the sum due and owing from the date payment is due until the date payment is received at the rate equal to [] ([]%) [*].

(e)

All amounts due under this Licence Agreement shall be paid in full without deduction for any applicable taxes, levies, imposts, duties and fees of whatever nature imposed by or under the authority of any government or public authority, except for tax legally required to be deducted or withheld. Where any sum due to be paid to Celltech is subject to any withholding or similar or other tax, the Parties shall take all reasonable steps to do all such acts and things and to sign all such deeds and documents as will enable them to take advantage of any applicable double taxation agreements to reduce the rate of withholding or similar taxes with the object of paying the sums due under deduction of a reduced rate of withholding tax or on a gross basis. In the event there is no double taxation agreement or the reduced rate of withholding tax under the relevant double taxation agreement is greater than [*] ([*]%), the Party making payment shall pay such withholding or similar tax, deduct the relevant amount from the payment due to the other Party, and secure and send to the other Party proof of such withholding or similar tax in a form in accordance with the relevant taxation authority as evidence of such payments. Each Party agrees to inform the other Party forthwith if it concludes that there is any law or practice or any change in such law or practice which requires it to deduct or withhold tax in respect of any payments due pursuant to this Licence Agreement at any time after the Licence Agreement Effective Date with a view to the Parties using their best endeavours to agree on the manner in which subsequent payments shall be made to reduce or eliminate the liability of both Parties to deduct or withhold any amount on account of tax.

(f)

All amounts due under this Licence Agreement shall be paid exclusive of any Value Added Tax (which, if applicable shall be payable by a Party in addition upon receipt of a valid Value Added Tax invoice). Each Party agrees to inform the other Party forthwith if it concludes that there is a Value Added Tax law or practice, or a change in such law or practice, which requires it to account for Value Added Tax on any payments due pursuant to this Licence Agreement at any time after the Licence Agreement Effective Date, with a view to the Parties using their

best endeavours to agree on the manner in which subsequent payments shall be made to reduce or eliminate the liability of the Parties to pay Value Added Tax.

6.2

Records; Audit. Amgen and its Affiliates shall keep and maintain complete and accurate records and books of account documenting in a detail sufficient to track and determine, in a manner consistent with GAAP, all revenues, expenses and Royalties due or other sums payable pursuant to this Licence Agreement and in compliance with the terms of this Licence Agreement. Such records shall be retained for a period of the later of (a) a [*] following the year in which any payments were made hereunder; (b) the expiration of the applicable tax statute of limitations (or any extensions thereof); or (c) such longer period as may be required by law. Amgen and its respective Affiliates shall permit independent accountants of internationally recognised standing retained by Celltech and reasonably acceptable to Amgen, upon reasonable prior written notice, to have access to its and its Affiliates' records and books and premises for the sole purpose of determining the correctness of any payment of Royalties and other amounts due and payable under this Licence Agreement for any year ending no more than [*] prior to the date of such request; provided however, that the books and records for any particular Calendar Year shall only be subject to one audit. Such examination shall be conducted during regular business hours and no more than once in each Calendar Year. The report of such accountant shall be limited to a certificate verifying (or not verifying, as the case may be) any report made or payment submitted by Amgen during such period. In the event the accountant shall be unable to verify the correctness of any such payment, the accountant's report shall specify why such payment is unverifiable and the amount of any discrepancy. Amgen shall receive a copy of each such report concurrently with receipt by Celltech, and the Parties shall use good faith efforts to resolve any discrepancies. All information contained in any such report shall be deemed Confidential Information hereunder. If such examination reveals that such costs or payments have been misstated, any adjustment shall be promptly refunded or paid, as appropriate. Celltech shall pay the fees and expenses of the accountant engaged to perform the audit, unless such audit reveals a net discrepancy of [*] ([*]%) or more for the period examined which is to the disadvantage of Celltech, in which case Amgen shall pay all reasonable costs and expenses incurred by Celltech in the course of making such determination. Upon the expiration of [*] following the end of any Calendar Year, the calculation of any such amounts payable with respect to such year shall be binding and conclusive upon Celltech and Amgen shall be released from any liability or accountability with respect to such amounts for such year.

ARTICLE 7

PUBLICATIONS

7.1

Procedure. Each Party (or its appropriate designees) shall determine the strategy for and co-ordinate the publication and presentation of results of studies of Licensed Antibody Products carried out under the Collaboration Agreement or which incorporate data generated under the Collaboration Agreement. Each Party to this Licence Agreement recognises that the publication of papers regarding results of and other information regarding activities under the Collaboration Agreement, including oral presentations and abstracts, may be beneficial to both Parties provided such publications are subject to reasonable controls to protect Confidential Information. In particular, it is the intent of the Parties to maintain the confidentiality of any Confidential Information included in any patent application until such patent application has been published. Accordingly, each Party will have the right to review and approve any paper proposed for publication by the other Party, including oral presentations and abstracts, which incorporates data generated under the Collaboration Agreement and/or includes Confidential Information of the other Party. Before any such paper is submitted for publication or an oral presentation is made, the publishing or presenting Party will deliver a complete copy of the paper or materials for oral presentation to the other Party at least [*] prior to submitting the paper to a publisher or making the presentation. The other Party will review any such paper and give its comments to the publishing Party within [*] of the delivery of such paper to the other Party. With respect to oral presentation materials and abstracts, the other Party will make reasonable efforts to expedite review of such materials and abstracts, and will return such items as soon as practicable to the publishing or presenting Party with appropriate comments, if any, but in no event later than [*] from the date of delivery to the other Party. Failure to respond within such [*] shall be deemed approval to publish or present. Celltech may withhold approval of any proposed Amgen publication or presentation to the extent such publication or presentation contains the Confidential Information of Celltech. Amgen may withhold approval of any proposed Celltech publication or presentation to the extent such publication or presentation is contrary to Amgen's publication strategy. The publishing or presenting Party will comply with the other Party's request to delete references to the other Party's Confidential Information in any such paper and agrees to withhold publication of same for an additional [*] in order to permit the Parties to obtain patent protection, if either of the Parties deems it necessary, in accordance with the terms of this Licence Agreement. [*].


7.2	Credit. Any such publication will include recognition of the contributions of the other Party according to standard practice for assigning scientific credit, either through authorship or acknowledgement, as may be appropriate.

INDEMNIFICATION

10.1

Indemnification by Celltech. Celltech hereby agrees to defend, hold harmless and indemnify (collectively, “Indemnify”) Amgen and its Affiliates, agents, directors, officers and employees (the “Amgen Indemnitees”) from and against any and all Third Party claims, suits, actions or demands and all out-of-pocket liabilities, costs, settlements, damages, expenses and/or losses paid to any Third Party bringing any such Third Party claim, as well as reasonable legal expenses and attorney and expert fees incurred in defending and/or compromising the same (“Amgen Loss(es)”) arising out of any of (a) any material breach or material default by Celltech of its material covenants and material obligations under this Licence Agreement; and (b) Celltech's negligence or intentional misconduct in carrying out its activities set forth in this Licence Agreement. Amgen shall provide Celltech with prompt written notice of any claim (with a description of the claim and the nature and amount, if determinable, of any such Amgen Loss) giving rise to the indemnification obligation pursuant to this Article 10.1 and the exclusive ability to defend such Third Party claim; provided however, that Celltech shall be relieved of its obligations only to the extent the failure to be provided prompt written notice shall have been prejudicial to its ability to defend such action. Amgen shall co-operate as reasonably requested in the defence of the claim; provided however, that Amgen shall have the right to retain its own counsel, at its own expense, if representation of the counsel of Celltech would be inappropriate due to actual or potential differing interests between the Parties. Amgen shall not settle any claim for Amgen Losses for which any Amgen Indemnitee is seeking to be Indemnified by Celltech, without Celltech's prior written consent. Celltech's obligation to Indemnify the Amgen Indemnitees pursuant to this Article 10.1 shall not apply to the extent any Amgen Losses (i) arise from the negligence or intentional misconduct of any Amgen Indemnitee; (ii) arise from any material breach by Amgen of this Licence Agreement; or (iii) for which Amgen is obligated to Indemnify the Celltech Indemnitees pursuant to Article 10.2 of this Licence Agreement.

10.2

Indemnification by Amgen. Amgen hereby agrees to Indemnify Celltech and its Affiliates, agents, directors, officers and employees (the “Celltech Indemnitees”) from and against any and all Third Party claims, suits, actions or demands and all out-of-pocket liabilities, damages, costs, settlements, expenses and/or losses paid to any Third Party bringing any such Third Party claim, as well as reasonable legal expenses and attorney and expert fees incurred in defending and/or compromising the same (“Celltech Loss(es)”) arising out of any of (a) any material breach or material default by Amgen of its material covenants and material obligations under this Licence Agreement; (b) Amgen's

negligence or intentional misconduct in carrying out its activities set forth in this Licence Agreement; and (c) the exercise of any rights by Amgen, its Affiliates, Sublicensees or any of their agents or distributors pursuant to this Licence Agreement (including any product liability claim). Celltech shall provide Amgen with prompt written notice of any claim (with a description of the claim and the nature and amount, if determinable, of any such Celltech Loss) giving rise to the indemnification obligation pursuant to this Article 10.2 and the exclusive ability to defend such Third Party claim; provided however, that Amgen shall be relieved of its obligations only to the extent the failure to be provided prompt written notice shall have been prejudicial to its ability to defend such action. Celltech shall co-operate as reasonably requested in the defence of the claim; provided however, that Celltech shall have the right to retain its own counsel, at its own expense, if representation of the counsel of Amgen would be inappropriate due to actual or potential differing interests between the Parties. Celltech shall not settle any claim for Celltech Losses for which any Celltech Indemnitee is seeking to be Indemnified by Amgen, without Amgen's prior written consent. Amgen's obligation to Indemnify the Celltech Indemnitees pursuant to this Article 10.2 shall not apply to the extent any Celltech Losses (i) arise from the negligence or intentional misconduct of any Celltech Indemnitee; (ii) arise from any material breach by Celltech of this Licence Agreement; or (iii) for which Celltech is obligated to Indemnify the Amgen Indemnitees pursuant to Article 10.1 of this Licence Agreement.

10.3

Insurance. Amgen shall maintain (through a captive insurer or Third Party insurer) appropriate product liability insurance with respect to Licensed Antibody Products and appropriate comprehensive general liability insurance to cover its obligations hereunder and which is/are consistent with normal business practices of prudent companies similarly situated. Amgen shall use reasonable endeavours to ensure that any insurance policy required by, and procured under, this Article 10.3 shall name Celltech as an additional insured. Such insurance shall not be construed to create a limit of the insuring Party's liability with respect to its indemnification obligations under this Article 10. Amgen shall furnish Celltech with a certificate(s) or other evidence from an insurance carrier showing all such insurance. Amgen shall diligently pursue recovery of insurance proceeds when a claim arises. The Parties acknowledge that it is the normal business practice of prudent companies similarly situated to have a reasonable level of uninsured loss.

10.4

Pre-Effective Date Losses. In accordance with Article 14.10 of the Collaboration Agreement, each Party shall retain its obligations for any liabilities, damages, expenses and/or losses accrued under the Collaboration Agreement prior to the Effective Date of Termination of the Collaboration Agreement (“Pre-Effective Date Losses”), and this Licence Agreement shall not release, waive, alter or otherwise modify the Parties' respective obligations thereunder. Other than with respect to

its obligation for any Pre-Effective Date Losses under and prior to the termination of the Collaboration Agreement, neither Party shall assume or be liable for (pursuant to this Licence Agreement) any liabilities, damages, expenses and/or losses resulting from or arising in connection with activities of the other Party which occurred on or prior to the Licence Agreement Effective Date.

to this Licence Agreement. Termination shall be effective upon expiry of the [*] notice period.

(c)

If Amgen fails to provide a document in accordance with Article 3.4(d) of the Collaboration Agreement in a timely manner as required by that Article 3.4(d), Celltech may (within [*] of the date on which Amgen was due to provide such document) request in writing that Amgen provide such document.

11.3 Termination for Default.

(a)

In the event any material representation or warranty made under the Collaboration Agreement by either Party shall have been untrue in any material respect and this has had a material and adverse effect on the other Party in relation to this Licence Agreement (“Representation Default”) or upon any material breach or material default of a material obligation of this Licence Agreement by a Party (“Performance Default”), the Party not in default (“Non-Defaulting Party”) must first give the other Party (“Defaulting Party”) written notice thereof (“Notice of Default”), which notice must state the nature of the Representation Default or Performance Default in reasonable detail and must request the Defaulting Party cure such Representation Default or Performance Default within [*], or if such Default cannot be cured, take such action as will substantially mitigate the material adverse effect of such Default on the other Party. During any such [*] period after receipt or delivery of a Notice of Default under this Article 11.3(a) for which termination of this Licence Agreement is a remedy, all of each Party's respective rights and obligations under this Licence Agreement (to the extent applicable) shall remain in force and effect. If the Defaulting Party shall dispute the existence, extent or nature of any default set forth in a Notice of Default, the Parties shall use good faith efforts to resolve the dispute.


(b)	In the event of a Representation Default or a Performance Default by Celltech that shall not have been cured or mitigated within the [*] period, as set forth in Article 11.3(a) above, Amgen,

at its option, may immediately terminate this License Agreement upon prior written notice to Celltech. Termination shall be effective upon the receipt of such notice by Celltech.


(c)	In the event of a Representation Default or a Performance Default by Amgen that shall not have been cured or mitigated within the [*] period, all as set forth in Article 11.3(a) above, Celltech, at its option, may immediately terminate this Licence Agreement upon prior written notice to Amgen. Termination shall be effective upon the receipt of such notice by Amgen.

11.4 Bankruptcy.

(a)

All rights and licences granted under or pursuant to this Licence Agreement by Celltech are, and shall otherwise be deemed to be licences of rights to “intellectual property”.

(b)

Without prejudice to Article 11.4(a), this Licence Agreement may be terminated by Celltech upon written notice to Amgen in the event that (i) Amgen shall make an assignment for the benefit of its creditors, file a petition in bankruptcy, petition or apply to any tribunal for the appointment of a custodian, receiver or any trustee for it or a substantial part of its assets, or shall commence any proceeding under any bankruptcy, reorganisation, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction (other than for the purposes of a solvent amalgamation or reconstruction) whether now or hereafter in effect; or (ii) if there shall have been filed against Amgen any such bona fide petition or application, or any such proceeding shall have been commenced against it in which an order for relief is entered or which remains undismissed for a period of ninety (90) days or more;
