Page 44

findings with the corresponding Evaluation Expert from the other Party. The Evaluation Experts will give the Targets a score for suitability against each criteria mentioned in Clause 5.7.1. The Evaluation Experts for each criteria shall prepare a joint report of their findings. The reports of all the Evaluation Experts shall be compiled together into a composite report on the Target, which shall constitute the “Target Evaluation Data Package”. The Target Evaluation Data Package may also include recommendations for further Target Evaluation Work to be conducted if the relevant Target is nominated as a Prioritised Alliance Target.

5.7.3 The Target Selection Committee shall oversee and direct the Target Evaluation Work. The costs of the Target Evaluation Work shall be shared by the Parties in accordance with Clause 13.3. The Target Selection Committee may at any time reject a Target from the Target Pool before a Target Evaluation Data Package has been completed in respect of such Target.

5.7.4 Each member of the Target Selection Committee shall be an Evaluation Expert.

5.7.5 The Target Selection Committee may call upon the Parties to carry out Target Validation Work to assist the Target Evaluation Work. Target Validation Work will consist of scientific exploration of a Target’s biology and shall include laboratory and desk based research. The Initial FTE Schedule includes the resources available for Target Validation Work.

5.7.6 The Target Selection Committee shall consider the Target Evaluation Data Package for each Target and shall decide upon a recommendation to the RMC in respect of that Target. The recommendation shall be either: (i) to designate the Target as a Prioritised Alliance Target; (ii) to reject the Target from the Target Pool; or (iii) to return the Target to the Target Pool for consideration at a later date.

Page 45

5.8 Prioritised Alliance Targets.

5.8.1 The RMC shall consider the recommendation of the Target Selection Committee prepared in accordance with Clause 5.7.6, and the relevant Target Evaluation Data Package. The RMC shall decide, in respect of each Target, whether to:

(a) designate it as a Prioritised Alliance Target;

(b) reject it from the Target Pool, in which case it shall cease to be an Alliance Target; or

5.8.2 Upon designation of a Prioritised Alliance Target, the RMC will appoint a Joint Discovery Project Team, drawing on the FTE resource, which shall prepare a Work Plan, Programme Budget, [***] and CDTP for a Joint Discovery Programme in respect of such Prioritised Alliance Target. The objective of each Work Plan will be to identify, select and optimise Antibodies that match the CDTP agreed for the Target in question. The Work Plan shall be substantially in the form set out in Schedule 5.8.2A and cover all of the activities to be performed by the Parties during the Joint Discovery Programme. The CDTP for Antibodies generated pursuant to the Work Plan shall be substantially in the form set out in Schedule 5.8.2B and shall be aligned to meet the needs of the relevant Disease Target Product Profile. The Programme Budget shall include details of the Programme Costs to be incurred in carrying out the relevant Work Plan.

5.8.3 The RMC may also require the Target Selection Committee to perform further Target Evaluation Work on the Prioritised Alliance Target which would enhance its potential as a subject for a Joint Discovery Programme.

5.8.4 On completion of the work mentioned in Clause 5.8.2 and 5.8.3, the Target Selection Committee will submit the completed Work Plan,

Page 46

CDTP Programme Budget and [***] to the RMC together with a risk resolution plan which will identify and describe the key risks associated with initiating a Joint Discovery Programme in respect of that Target.

5.9 Preparation for Joint Discovery Programmes.

5.9.1 The RMC will review the Work Plan, CDTP, Programme Budget and [***] and report prepared by the Target Selection Committee pursuant to Clause 5.8.4 for each Prioritised Alliance Target.

5.9.2 Following the review set out in Clause 5.9.1, in respect of each such Prioritised Alliance Target, the RMC shall decide whether:-

(a) to designate it as a candidate for a Joint Discovery Programme, in which case the RMC shall approve the Work Plan, CDTP, Programme Budget and [***] for the Joint Discovery Programme and rank it in order of those Joint Discovery Programmes next to be started. The first ranked such Joint Discovery Programme shall be known as the “Next Start”;

(b) to reject it from the Target Pool, in which case it shall cease to be an Alliance Target; or

(c) to return it to the Target Pool.

If the RMC cannot agree on which of the above options to adopt, the Target in question shall be considered a “Blocked Target”. A Blocked Target remains in the Target Pool, but does not count towards the maximum number in the Target Pool. Subject always to Clause 6.7, neither Party shall conduct any discovery or development work on a Blocked Target.

5.10 Continuous Nature of Process. The processes and work described in Clauses 5.2 to 5.9 above shall continue throughout the Discovery Initiation Phase, to ensure that the provisions of Clause 4 are met. At least once every Initiation Year the RMC shall report to the ASC details of the manner in which the RMC is ensuring that the provisions of Clause 4 are

Page 47

met. The ASC shall consider the report of the RMC at the meeting following the report.

5.11 Extension of Discovery Initiation Phase. The Parties may agree to extend the Discovery Initiation Phase provided such agreement shall be in writing and signed by authorised signatories of both Parties.

5.12 Target Nomination Resources. The annual FTE resource for activities contemplated in this Clause 5 is included in the number set out in the Initial FTE Schedule. The figures in the Initial FTE Schedule are based on the Parties’ best assessment at the date of signature of this Agreement of the FTE resource required to meet their obligations under Clause 4. It is the responsibility of the RMC and Target Selection Committee to manage and allocate the FTE resource available for the activities contemplated in this Clause 5 within the resource set out in the Initial FTE Schedule. In the event that, pursuant to Clause 4.1, the number of Joint Discovery Programmes is increased, the number of FTEs in the Initial FTE Schedule will be increased in accordance with the mechanism in Clause 6.2 subject to the maximum set out in the FTE Schedule.

6. Discovery Programmes

6.1 Joint Discovery Programmes. The Parties acknowledge and agree that within [***] following the Effective Date they will identify [***] Joint Discovery Programmes which will commence as soon as practicable following the expiry of such [***] month period, but which may start earlier if the RMC so agrees. Forthwith following the Effective Date AstraZeneca may by written notice to CAT request information relating to a CAT Existing Discovery Programme. The information request may cover any and all available scientific results and data (including pre-clinical, clinical, pharmacokinetic and toxicological data) and information relating to any IP Protection Rights relevant to the CAT Existing Discovery Programme in question. CAT shall provide such information to AstraZeneca provided always that the request cannot oblige CAT to undertake more work in relation to that CAT Existing Discovery

Page 48

Programme. AstraZeneca may by written notice to CAT (an “Adoption Notice”) adopt any CAT Existing Discovery Programme at any time prior to the end of [***] following the Effective Date. Upon receipt of the Adoption Notice by CAT, the CAT Existing Discovery Programme shall for all purposes be considered to be a Joint Discovery Programme and if the CAT Existing Discovery Programme is still in its Lead Isolation and Optimisation Phase or before, it will count towards the [***] Joint Discovery Programmes to be initiated pursuant to the first sentence of this Clause 6.1. If any CAT Existing Discovery Programme is not so adopted by AstraZeneca CAT shall have no further obligation to AstraZeneca in respect thereof and they will be outside the scope of the Alliance. As soon as the RMC decides to terminate any of the first [***] Joint Discovery Programmes which is still in its Lead Isolation and Optimisation Phase or decides that the Lead Isolation and Optimisation Phase of any Joint Discovery Programme has been satisfactorily completed it will arrange for the Next Start to commence promptly thereafter. This procedure shall be repeated throughout the Discovery Initiation Phase as each Joint Discovery Programme still in its Lead Isolation and Optimisation Phase is terminated or that Lead Isolation and Optimisation Phase is completed to the satisfaction of the RMC; provided always that there are no more than [***] Joint Discovery Programmes (or such other number of Joint Discovery Programmes as set pursuant to Clause 4.1) in their Lead Isolation and Optimisation Phase running in parallel at any one time.

6.2 Conduct of Joint Discovery Programmes. The Joint Discovery Project Team shall be responsible for completing the relevant Joint Discovery Programme in accordance with the Work Plan, CDTP, Programme Budget and [***] approved by the RMC for that Joint Discovery Programme. Each Joint Discovery Project Team shall under the direction and supervision of the RMC: (a) perform or cause to be performed its tasks under each Work Plan with reasonable skill and care in good scientific manner and in compliance in all material aspects with all Applicable Laws; (b) allocate sufficient time, effort, equipment and skilled personnel in accordance with the Work Plan, Programme Budget, Budget and [***]

Page 49

to complete such activities promptly; and (c) report to the RMC regularly. It is acknowledged that each Party and the Joint Discovery Project Team shall have the right to make day-to-day operational decisions as to how to discharge these obligations within the framework of each Work Plan. The maximum overall annual FTE resource for activities in relation to the Joint Discovery Programmes and the Target Selection Process will be no more than the number set out in the Initial FTE Schedule. The figures in the Initial FTE Schedule are based on the Parties’ best assessment at the date of signature of this Agreement of the FTE resource required to meet their obligations under Clause 4. It is the responsibility of the RMC to manage and allocate the FTE resource available to the Joint Discovery Programmes as set out in the Initial FTE Schedule. Each Party will make available the FTE resources set out in the Initial FTE Schedule, but neither Party may be required to increase its FTE resource allocated to the Joint Discovery Programmes without its prior approval. In the event that, pursuant to Clause 4.1, [***] requires the RMC to increase the number of Joint Discovery Programmes that are running in parallel in their Lead Isolation and Optimisation Phase the Parties will (unless otherwise agreed) increase the number of FTEs included in the Initial FTE Schedule by the amount set out in the Initial FTE Schedule for such increase but subject always to the maximum FTE resource specified in the FTE Schedule.

6.3 Programme Progress Reports. At times determined by the RMC, the Joint Discovery Project Teams shall provide the RMC with a summary written progress report containing information on all Results generated under their Joint Discovery Programme and not previously reported to the RMC. The RMC may provide further instructions on the timing and content of these reports.

6.4 Termination of Joint Discovery Programme by RMC. The RMC may terminate a Joint Discovery Programme if the RMC considers it is unlikely to result in Antibodies which will achieve CDTP-Matching. If the RMC cannot agree on such termination the Joint Discovery Programme will continue. If a Joint Discovery Programme is terminated after it has

Page 50

completed the Lead Isolation and Optimisation Phase, the RMC will commence a new Joint Discovery Programme as soon as there is sufficient FTE resource that can carry out the Lead Isolation and Optimisation Phase on the Next Start; provided always that there are no more than [***] Joint Discovery Programmes (or such other number of Joint Discovery Programmes as set pursuant to Clause 4.1) in their Lead Isolation and Optimisation Phase running in parallel at any one time. Any Antibodies raised in a Joint Discovery Programme which is terminated may be used by the Parties for research work outside the Alliance, or if not so used, shall be destroyed. The Target forming the subject-matter of the terminated Joint Discovery Programme shall cease to be an Alliance Target.

6.5 Completion of Joint Discovery Programme and CDTP-Matching. Upon completion of the Work Plan for a Joint Discovery Programme, the Joint Discovery Project Team will promptly compile a data package, in a format set by the RMC, setting out all of the results of the Joint Discovery Programme (the “Final Discovery Data Package”). The Final Discovery Data Package shall be submitted to the RMC, together with the Joint Discovery Project Team’s recommendations. The RMC shall promptly consider whether the Joint Discovery Programme has been successfully completed, and will make one of the following decisions:

6.5.1 more work is required, in which case the Joint Discovery Project Team will undertake the work and once the work has been carried out, the provisions of this Clause 6.5 shall be re-applied [***]; or

6.5.2 the Joint Discovery Programme has failed, in which case the Target which was the subject of the Joint Discovery Programme will cease to be an Alliance Target and the provisions in the last two sentences of Clause 6.4 shall apply; or

6.5.3 the Joint Discovery Programme has been successful, in which case the RMC shall record those Exclusive Antibodies and genes encoding the

Page 51

Exclusive Antibodies and the Parties will apply the procedure in Clause 6.17.

6.6 [***]

Page 52

Page 53

6.7 AstraZeneca Discovery Programme Initiation. AstraZeneca may initiate [***] [***] AstraZeneca Discovery Programmes in any Initiation Year. AstraZeneca may select for the subject matter of [***].

6.8 Planning and Conduct of AstraZeneca Discovery Programmes. In respect of each AstraZeneca Discovery Programme the Work Plan, CDTP and programme budget shall be determined in AstraZeneca’s sole discretion and disclosed to the RMC for the purposes of consideration and comment. AstraZeneca shall be the sole judge of whether a CDTP for an AstraZeneca Discovery Programme has been achieved. CAT shall in its absolute discretion have the right to refuse to carry out the Work Plan if this would cause it to exceed the FTE resource it has available for the AstraZeneca Discovery Programmes as specified below and in such case the AstraZeneca Discovery Programme shall not proceed. The RMC shall establish a Joint Discovery Project Team, and the Joint Discovery Project Team shall be responsible for completing the relevant AstraZeneca Discovery Programme in accordance with the relevant Work Plan, CDTP and programme budget. The Joint Discovery Project Team shall be under the supervision and direction of the RMC[***]. In respect of AstraZeneca Discovery Programmes, each Joint Discovery Project Team shall: (a) perform or cause to be performed its tasks under the relevant Work Plan with reasonable skill and care in good scientific manner and in compliance in all material aspects with all Applicable Laws; (b) allocate sufficient time, effort, equipment and skilled personnel to complete such activities

Page 54

promptly; and (c) report to the RMC regularly. It is acknowledged that each Party shall have the right to make day-to-day operational decisions as to how to discharge these obligations within the framework of each Work Plan. CAT’s costs of performing its tasks under the relevant Work Plan shall be borne by AstraZeneca as set out in Clause 13.4. The resources required by the Parties to conduct AstraZeneca Discovery Programmes are not part of the Initial FTE Schedule or the FTE Schedule. In performing its obligations under this Clause 6.8, CAT shall not be obliged to devote more than [***] FTEs in any Calendar Year to an AstraZeneca Discovery Programme. AstraZeneca shall give CAT [***] notice of initiation of an AstraZeneca Discovery Programme.

6.9 Termination of AstraZeneca Discovery Programme. AstraZeneca may in its absolute discretion decide to terminate an AstraZeneca Discovery Programme at any time for any reason, including for the reason where AstraZeneca decides not to commence an AstraZeneca Development Programme under Clause 7.6.1. AstraZeneca shall give CAT written notice of such termination and CAT may, but shall not be obliged to continue the AstraZeneca Discovery Programme independently of AstraZeneca and outside the Alliance on giving written notice to AstraZeneca in which case the Target forming the subject-matter of the AstraZeneca Discovery Programme shall cease to be an Alliance Target and the provisions of the Handover Schedule shall apply. AstraZeneca shall be entitled to the milestones and royalties set out in Clauses 14.3.1 and 15.2.2 in relation to any Product arising out of the discovery programme or development programme conducted by CAT in respect of its continuation of the AstraZeneca Discovery Programme as set out in this Clause 6.9.

6.10 CAT Independent Targets. [***]

6.11 Initiation and Conduct of CAT Alliance Discovery Programmes.

6.11.1 Initiation. CAT may, at any time following the expiry of [***] from the Effective Date, initiate [***] CAT Alliance Discovery Programmes

Page 55

in respect of any Alliance Targets which are not Prioritised Alliance Targets [***] and against which no other Discovery Programme has been initiated, provided always that (i) such CAT Alliance Discovery Programmes shall be directed at disease indications other than those which are addressed by the Alliance Discovery Goals and (ii) prior to initiating a CAT Alliance Discovery Programme, CAT discloses to the RMC the disease indication the subject of the proposed CAT Alliance Discovery Programme and any target evaluation data package that may have been prepared by CAT (or otherwise the results of any target evaluation work conducted by CAT) with respect to the Target, and gives the RMC [***] notice of CAT’s intention to start the CAT Alliance Discovery Programme. Any Alliance Target that is the subject of a CAT Alliance Discovery Programme shall remain an Alliance Target. However, if the Parties subsequently undertake a Joint Discovery Programme in respect of the same Target they shall not be entitled to develop a Product which contains a Collaboration Antibody which has the identical composition of matter as the Antibody which is the subject of the CAT Alliance Discovery Programme unless AstraZeneca adopts the CAT Alliance Discovery Programme pursuant to Clause 6.12. The Parties acknowledge for the avoidance of doubt that the provisions of Clauses 6.14, 6.16 and 6.17 shall not apply to any CAT Alliance Discovery Programme.

6.11.2 Conduct. CAT Alliance Discovery Programmes shall be managed and funded solely by CAT in its sole discretion. CAT shall set its own criteria for CAT CDTPs and shall be the sole judge of whether they have been achieved. CAT shall provide reports on progress of CAT Alliance Discovery Programmes to the RMC every 6 months and at the point when the CAT CDTP is matched. A representative from AstraZeneca may attend CAT’s monthly meetings of the discovery project team which is managing the CAT Alliance Discovery Programme.

Page 56

6.12 Adoption of CAT Alliance Discovery Programmes. AstraZeneca may by written notice to CAT (an “Adoption Notice”) adopt any CAT Alliance Discovery Programme at any time prior to the end of [***] following the achievement of CAT CDTP in respect of the CAT Alliance Discovery Programme. Upon receipt of the Adoption Notice, the provisions of the Handover Schedule shall apply and the CAT Alliance Discovery Programme shall for all purposes be considered to be a Joint Discovery Programme and the relevant provisions of this Clause shall apply accordingly, including for the sake of clarity Clauses 6.16 and 6.17.

6.13 Collaboration Results and Information Transfer. Each Party shall, and shall cause its Affiliates to, without additional compensation and at such Party’s sole expense, make available to the other Party the Target Know-How and/or Collaboration Results specified in the Work Plan for each Joint Discovery Programme or AstraZeneca Discovery Programme as soon as practicable after the initiation of the relevant Discovery Programme and thereafter as soon as practicable upon making of such Results.

6.14 Subcontracting. Each Party shall be solely responsible for successfully completing its activities set out in the Work Plan for a Joint Discovery Programme and may only engage a subcontractor to carry out a portion of such activities to the extent permitted by the RMC. Each Party shall be solely responsible for successfully completing its activities set out in the Work Plan for an AstraZeneca Discovery Programme and may only engage a subcontractor to carry out a portion of such activities to the extent permitted by AstraZeneca, such consent not to be unreasonably withheld or delayed. Any such permitted subcontract shall be subject to the applicable terms and conditions of this Agreement, including Clauses 17 and 20 provided, however, that each Party shall remain ultimately responsible for the performance of its obligations under this Agreement. Any fees or costs due any such subcontractor shall be at the sole expense of the Party appointing the sub-contractor, subject always to the provisions of Clause 13.3. For the avoidance of doubt, all work subcontracted to a Third Party in respect of a Discovery Programme or a Development

Page 57

Programme which is to be charged to the Alliance will be charged at cost and neither Party shall be entitled to a xxxx-up or profit on any work subcontracted out to a Third Party.

6.15 Records. CAT and AstraZeneca shall each maintain, or cause to be maintained, records of its respective activities under the Joint Discovery Programmes and AstraZeneca Discovery Programmes in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes, which shall be complete and accurate and shall fully and properly reflect all work done and results achieved in the performance of its respective activities under the Discovery Programmes, and which shall be retained by such Party for as long as may be required by Applicable Law. Each Party shall have the right, during normal business hours and upon reasonable notice, to inspect and copy any such records.

6.16 Preparation for Joint Development Programmes. As a Joint Discovery Programme progresses, the GPT allocated to such Joint Discovery Programme will, working with the RMC and Joint Discovery Project Team, prepare a Work Plan, TPP, Programme Budget and[***] for a Joint Development Programme in respect of one or more of the Collaboration Antibodies expected to be identified in the Joint Discovery Programme [***]. The GPT shall ensure that such Work Plan, TPP, Programme Budget [***]are completed[***] in respect of the Joint Discovery Programme. The objective of the Work Plan will be to develop the selected CDs to successful Proof of Concept addressing the TPP prepared by the GPT. The Work Plan shall cover all of the activities to be performed by the Parties during the Joint Development Programme. The Work Plan will: (i) describe all relevant elements of [***] for the selected CD and shall [***]; (ii) include the conduct of Significant Activity at least [***]; and (iii) [***]. The specific TPP shall be substantially in the form set out in Schedule 6.16 for CDs generated pursuant to the Joint Discovery Programme. The corresponding Programme Budget shall include details of the anticipated Programme Costs of carrying out the Programme.

Page 58

6.17 Option Point 1.

6.17.1 If the RMC decides there has been CDTP-Matching in respect of Antibodies arising from a Joint Discovery Programme or otherwise decides that the Joint Discovery Programme has been successful under Clause 6.5.3, the RMC will provide the Parties with the relevant Final Discovery Data Package and the RMC’s recommendations within [***] of the RMC’s decision. The relevant GPT will also provide the Parties with the Work Plan, TPP, Programme Budget and [***] in respect of the proposed Joint Development Programme prepared in accordance with Clause 6.16, within [***] of the RMC’s decision.

6.17.2 Each Party shall independently review the materials referred to in Clause 6.17.1 and undertake its own decision-making process. Within [***] of receipt of the materials, each Party shall inform the other of its decision whether to progress the proposed CDs into a Joint Development Programme. The consequences of the Parties’ decision are as follows:

(a) If both Parties decide to progress, the Parties shall commence a Joint Development Programme in respect of at least one of the CDs identified in the Work Plan for which there has been CDTP-Matching;

(b) If AstraZeneca decides to progress, but CAT decides not to progress, AstraZeneca may commence an AstraZeneca Development Programme in respect of at least one of the CDs for which there has been CDTP-Matching, and the provisions of the Handover Schedule shall apply;

(c) If CAT decides to progress, but AstraZeneca decides not to progress, CAT may commence a CAT Alliance Development Programme in respect of at least one of the CDs for which there has been CDTP-Matching, and the provisions of the Handover Schedule shall apply;

Page 59

(d) If neither Party decides to progress CAT shall be free to seek Third Party licensees for such CDs and the Target shall no longer be an Alliance Target, [***]. If the Target and CDs are out-licensed, [***]. If no out-licence has been granted by CAT within [***] of the mutual decision not to progress, the Antibodies may be used by the Parties for research work outside the Alliance, or if not so used, shall be destroyed.

7. Development Programmes

7.1 Joint Development Programmes.

7.1.1 The Parties shall commence a Joint Development Programme in the circumstances set out in Clause 6.17.2(a).

7.1.2 The Joint Development Programme shall be conducted and managed by the GPT which has had involvement in the relevant Joint Discovery Programme. The GPT shall be accountable for the delivery of all elements of the Work Plan for the Joint Development Programme up to Option Point 2. This will include the preparation and conduct of all clinical trials.

7.1.3 The GPT shall conduct the Joint Development Programme in accordance with the Work Plan, TPP, Programme Budget [***] disclosed to the Parties pursuant to Clause 6.17.1. The GPT may amend the Work Plan and keep the Programme Budget up to date, subject to CAT’s rights set out in Clause 7.5.

7.1.4 The GPT may allocate work to the satellite teams which report to the GPT. The satellite team for supply of early clinical trial material will be led by CAT unless the GPT decides otherwise. The Parties shall ensure that their satellite team members carry out such work. During the term of any Joint Development Programme each Party shall: (a) perform or cause to be performed its obligations under the relevant Work Plan with reasonable skill and care in good scientific manner and in compliance in all material aspects with all Applicable Law,

Page 60

including good laboratory practices and good clinical practices; and (b) allocate sufficient time, effort, equipment and skilled personnel to complete such activities successfully. In particular under the Work Plan AstraZeneca shall have responsibility for preparation and/or compilation of the various components of all applications for Health Registration Approvals and other similar regulatory submissions in each country in relation to the Joint Development Programme. AstraZeneca shall be responsible for all communications with the Regulatory Authorities in connection therewith provided always that CAT shall be entitled to have [***] attend all key meetings or conference calls with the Regulatory Authorities in the Major Markets as an observer whenever permitted to do so by the relevant Regulatory Authority.

7.1.5 Any Joint Development Programme may be undertaken on one or more Exclusive Antibodies in parallel or sequentially where the relevant GPT considers it would be prudent to do so. In the event that the results of a Joint Development Programme reveal that the lead CD then under development is unsuitable for further development for whatever reason the relevant GPT shall be entitled to terminate the development of that lead CD provided that it selects another CD from the Exclusive Antibodies identified in the relevant Discovery Programme in respect of which to continue the Joint Development Programme. Such selection shall take place as soon as practicable and in any event within [***] of the termination of the development of the lead CD. For the avoidance of doubt, the termination of the development of the lead CD and the continuation of the Joint Development Programme with another Exclusive Antibody shall not be classed as a termination of a Joint Development Programme for the purposes of Clause 7.2.

7.1.6 Prior to each GPT meeting, the GPT’s satellite teams shall provide the GPT with a written progress report on each Joint Development

Page 61

Programme. The GPT may provide further instructions on the timing and content of these reports.

7.2 Termination of a Party’s Participation in a Joint Development Programme.

7.2.1 If either Party determines, in its sole discretion, for any reason that it is not in its interests to continue a Joint Development Programme then the deciding Party shall promptly notify the other Party in writing of such determination and provide it with the pertinent information with respect thereto. In such event, the Party having made such determination may terminate its involvement in the Joint Development Programme in question upon [***] prior written notice save where the termination is related to a safety reason, in which case the notice shall be a reasonable period of time but commensurate with any danger to patients. The terminating Party shall together with such notice provide the other Party with a copy of all Clinical Data and Know-How generated within the Joint Development Programme in its possession.

7.2.2 Subject to Clause 7.1.5, if one Party exercises its rights under Clause 7.2.1 to terminate its involvement in a Joint Development Programme, the other Party shall have the right to elect by written notice to the terminating Party (to be given [***] of receipt of the termination notice and information package under Clause 7.2.1) to continue the development of the Exclusive Antibodies and/or Product in question and in the event of such election the provisions of the Handover Schedule shall apply. In that event the Joint Development Programme in question shall become an AstraZeneca Development Programme (in which case CAT shall be entitled to the milestone and royalty provisions set out in Clauses 14.2.3 and 15.1.3.) or a CAT Alliance Development Programme (in which case AstraZeneca shall be entitled to the milestone and royalty provisions set out in Clauses 14.3.3 and 15.2.4) as the case may be, save that in this latter case the provisions of Clause 7.9 shall not apply. If the non-terminating Party decides not to continue the Development Programme CAT shall have the right to

Page 62

out - license the Development Programme[***]. If it is out-licensed the [***]. If no out-licence has been granted within [***] of the termination then the Exclusive Antibodies which were the subject of the preceding Discovery Programme may be used by the Parties for research work outside the Alliance, or if not so used, shall be destroyed, and the Alliance Target, which was the subject of the Development Programme, will cease to be an Alliance Target.

7.3 Preparation for Final Development. As a Joint Development Programme progresses, the GPT will prepare a Work Plan, Programme Budget and[***] for the Final Development in respect of the Product expected to be developed in the Joint Development Programme [***] including [***]. The objective of the Work Plan will be to complete the Final Development of the Product. The Work Plan relating to the Final Development of the Product shall include the conduct of Significant Activity [***].

7.4 Completion of Joint Development Programme and Proof of Concept. Prior to the expiry of [***] following the decision by the GPT either (i) that the CD which is the subject of the Joint Development Programme addresses the TPP or (ii) to make an internal investment proposal to initiate, in respect of the CD which is the subject of the Joint Development Programme, Phase III Clinical Trials or other clinical trials of a pivotal nature at a standard suitable to obtain a Health Registration Approval in a Major Market, the GPT shall compile a report, in a format set by the ASC, which shall include the results of the relevant Joint Development Programme, the proposed Work Plan, Programme Budget and[***]for the Work Plan established under Clause 7.3[***]. The Programme Budget shall clearly set out Programme Costs of Final Development. The report shall be made available for both Parties to consider in relation to their decisions at Option Point 2. AstraZeneca shall not initiate any Phase III Clinical Trial or other clinical trials of a pivotal nature or make any BLA filing [***]

Page 63

Page 64

7.6 AstraZeneca Development Programmes.

7.6.1 AstraZeneca may commence an AstraZeneca Development Programme where:

(a) AstraZeneca decides at its sole discretion that the CDTP for a Target which has been the subject of an AstraZeneca Discovery Programme has been matched by one or more Collaboration Antibodies discovered in the relevant AstraZeneca Discovery Programme;

(b) where there has been a CAT Opt-out at CDTP.

7.6.2 For the avoidance of doubt it is declared that an AstraZeneca Development Programme also arises where there has been a CAT Abandonment of Joint Development Programme.

7.6.3 AstraZeneca may decide to undertake more than one AstraZeneca Development Programme in respect of Exclusive Antibodies discovered in a single Discovery Programme and the provisions of this Clause 7.6 shall apply to each such AstraZeneca Development Programme. AstraZeneca shall be entitled to commence an AstraZeneca Development Programme in respect of an Exclusive Antibody arising from an AstraZeneca Discovery Programme (or a Joint Discovery Programme where there has been a CAT Opt-out at CDTP) at any time in parallel or sequentially notwithstanding that there may be one or more AstraZeneca Development Programmes relating to the Target forming the subject-matter of such AstraZeneca Development Programme ongoing, completed or abandoned. However, in the event that the results of an AstraZeneca Development Programme arising from a Joint Discovery Programme reveal that the CD under development is unsuitable for further development for whatever reason the relevant GPT shall be entitled to terminate such development provided that it selects another CD from the Exclusive Antibodies identified in the relevant Discovery Programme in respect of which to continue the AstraZeneca Development Programme. Such selection shall be made as soon as practicable and in any event within [***] of the termination of the development of the previous CD. For the avoidance of doubt, the termination of the development of the lead CD and the continuation of the AstraZeneca Development Programme

Page 65

with another Exclusive Antibody shall not be classed as an AstraZeneca Abandonment of AstraZeneca Development Programme for the purposes of Clause 7.7. Where the AstraZeneca Development Programme(s) and any subsequent AstraZeneca Product arise from an AstraZeneca Discovery Programme the milestones and royalties set out in Clauses 14.2.1 and 15.1.1 shall be payable to CAT. Where the AstraZeneca Development Programme(s) and any subsequent AstraZeneca Product arise where there has been either a CAT Opt-out at CDTP or a CAT Abandonment of Joint Development Programme the milestones and royalties set out in Clauses 14.2.2 or 14.2.3, and 15.1.2 or 15.1.3 shall be payable accordingly.

7.6.4 A GPT in respect of an AstraZeneca Development Programme shall be appointed and shall prepare a Work Plan for the AstraZeneca Development Programme. Where there has been a CAT Opt-out at CDTP, the GPT will adopt the Work Plan prepared by the GPT for the purposes of Option Point 1. At least once per Calendar Year AstraZeneca shall provide CAT with a report produced by the relevant GPT for each AstraZeneca Development Programme. AstraZeneca may, but shall not be obliged, to contract certain services and supply of early clinical trial material to CAT, including process development in support of AstraZeneca Development Programmes. The precise scope of the services, the quantity, quality and specification of the clinical trial materials, regulatory compliance including cGMP and the timelines shall be agreed on a case by case basis. AstraZeneca must exercise this option to take the services of CAT within six (6) months of the decision to commence an AstraZeneca Development Programme under the terms of a contract to be agreed, but will be at the FTE Rate for Services, the Fully Burdened Manufacturing Cost and the External Costs. Notwithstanding any other provision of this Clause 7.6, AstraZeneca Development Programmes shall be solely managed by AstraZeneca and all decisions in relation to AstraZeneca Development Programmes shall be made in AstraZeneca’s sole discretion. Any GPT established by AstraZeneca to manage an AstraZeneca Development

Page 66

Programme shall consist solely of AstraZeneca members, unless otherwise agreed. AstraZeneca may make reasonable requests of CAT to provide any assistance necessary for obtaining Health Registration Approval by reason of CAT’s involvement in the AstraZeneca Development Programme (if any), such assistance not to be unreasonably withheld or delayed by CAT.

7.7 Termination of an AstraZeneca Development Programme. AstraZeneca may in its absolute discretion decide to terminate an AstraZeneca Development Programme prior to completion of the Development Programme to Proof of Concept. Within thirty (30) days of making its decision to do so it will notify CAT in writing and will provide CAT with all Clinical Data and Know-How generated within the AstraZeneca Development Programme and CAT shall have [***] from receipt of the same in which to decide whether to adopt the Development Programme as a CAT Alliance Development Programme save that if CAT does so the provisions of Clause 7.9 shall not apply in these circumstances. The provisions of the Handover Schedule shall apply if CAT issues a written notice to AstraZeneca within such [***] period exercising its rights under this Clause 7.7. If CAT adopts the programme as a CAT Alliance Development Programme AstraZeneca shall be entitled to the milestones and royalties set out in Clauses 14.3.4 and 15.2.5.

7.8 CAT Alliance Development Programmes.

7.8.1 CAT may commence a CAT Alliance Development Programme where (i) CAT decides at its sole discretion to do so, the CAT CDTP in a relevant CAT Alliance Discovery Programme having been met by one or more CDs in circumstances where AstraZeneca has not exercised its rights under Clause 6.12; (ii) there has been an AstraZeneca Opt-out at CDTP.

7.8.2 For the avoidance of doubt it is also declared that a CAT Alliance Development Programme arises where there has been an AstraZeneca Abandonment of Joint Development Programme and where there has

Page 67

been an Abandonment of AstraZeneca Development Programme in relation to which CAT has exercised its rights under Clauses 7.2.2 or 7.7 as the case may be.

7.8.3 CAT may decide to undertake more than one CAT Alliance Development Programme in respect of Exclusive Antibodies discovered in a single CAT Alliance Discovery Programme and the provisions of this Clause 7.8 shall apply to each such CAT Alliance Development Programme. CAT shall be entitled to commence a CAT Alliance Development Programme in respect of an Exclusive Antibody arising from a CAT Alliance Discovery Programme (or a Joint Discovery Programme where there has been an AstraZeneca Opt-out at CDTP or an AstraZeneca Discovery Programme where there has been an AstraZeneca Abandonment of AstraZeneca Discovery Programme) at any time in parallel or sequentially notwithstanding that there may be one or more CAT Alliance Development Programmes relating to the Target forming the subject-matter of such CAT Alliance Development Programme ongoing, completed or abandoned. However, in the event that the results of a CAT Alliance Development Programme arising from a Joint Discovery Programme reveal that the CD under development is unsuitable for further development for whatever reason CAT shall be entitled to terminate such development provided that it selects another CD from the Exclusive Antibodies identified in the relevant Joint Discovery Programme in respect of which to continue the CAT Alliance Development Programme. Such selection shall be made as soon as practicable and in any event within [***] of the termination of the development of the previous CD. Where the CAT Alliance Development Programme(s) and any subsequent CAT Alliance Product arise where there has been either an AstraZeneca Opt-out at CDTP or an AstraZeneca Abandonment of Joint Development Programme the milestones and royalties set out in Clauses 14.3.2 or 14.3.3, and 15.2.3 or 15.2.4 shall be payable accordingly.

Page 68

7.8.4 CAT Alliance Development Programmes will be conducted and managed solely by CAT and entirely at CAT’s cost.

7.8.5 CAT shall provide AstraZeneca with reports of progress on CAT Alliance Development Programmes no less than once every Calendar Year.

7.9 Adoption of CAT Alliance Development Programme [***].

7.10 Collaboration Results and Information Transfer.

Each Party shall, and shall cause its Affiliates to, without additional compensation and at such Party’s sole expense make available to the other Party the Target Know-How and/or Collaboration Results and/or any AstraZeneca Other Background Technologies specified in the Work Plan (in the case of AstraZeneca Other Background Technologies with the agreement of AstraZeneca) for each Joint Development Programme as soon as practicable after the initiation of the relevant Joint Development Programme and thereafter as soon as practicable after making such Results.

7.11 Subcontracting. CAT shall be solely responsible for successfully completing its activities set out in the Work Plan for a Joint Development Programme and AstraZeneca Development Programme. CAT shall conduct and carry out all activities provided for under each Joint Development Programme, and to the extent contracted under each AstraZeneca Development Programme, through its employees at CAT’s site(s) unless and only to the extent that the GPT consents in writing to CAT engaging a subcontractor to carry out a portion of such activities, such consent not to be unreasonably withheld or delayed. The GPT shall set, and CAT shall comply with, any sub-contracting strategy for any Joint Development Programme or AstraZeneca Development Programme.

7.12 Records. CAT and AstraZeneca each shall maintain, or cause to be maintained, records of its respective activities under Joint Development Programmes and AstraZeneca Development Programmes in sufficient detail and in good scientific manner appropriate for patent and regulatory

Page 69

purposes, which shall be complete and accurate and shall fully and properly reflect all work done and results achieved in the performance of its respective activities under Joint Development Programmes and AstraZeneca Development Programmes, and which shall be retained by such Party for as long as may be required by Applicable Law. Each Party shall have the right, during normal business hours and upon reasonable notice, to inspect and copy any such records.

7.13 Option Point 2.

7.13.1 Each Party shall independently review the materials referred to in Clause 7.4 and undertake its own decision-making process. Within [***] days of receipt of the materials, AstraZeneca shall inform CAT of whether it proposes to undertake Final Development of the relevant Alliance Product or whether it proposes to abandon the relevant CD.

7.13.2 if AstraZeneca informs CAT that it proposes to abandon the relevant CD, CAT shall have [***] days in which to inform AstraZeneca either:-

(a) that it wishes to adopt such CD and initiate its Final Development, in which case the provisions of the Handover Schedule shall apply and AstraZeneca shall be entitled to the milestone and royalty payments set out in Clauses 14.3.5 and 15.2.6; or

(b) that it wishes to abandon the CD, in which case CAT shall have the right to seek to out-license the Target and all other Exclusive Antibodies from the same Discovery Programme[***]. If they are out-licensed the proceeds shall be [***].

Page 95

15.5 Combination Products. With respect to Combination Products, the Annual Net Sales used for the calculation of the royalties under this Clause 15 shall be determined as follows:

A		X    Net Sales of the Combination Product, where:
A+B
A =		standard sales price of the ready for sale form of a Product containing the same amount of Collaboration Antibody or Antibodies as its sole active ingredient or ingredients as the Combination Product in question contains, in the given country.
B =		standard sales price of the ready­for­sale form of a product containing the same amount of the other therapeutically active ingredient(s) as is contained in the Combination Product in question, in the given country.

Provided that if, in a specific country: (i) A is known but the other therapeutically active ingredient(s) in such Combination Product are not sold separately in that country in products with the same quantity of active ingredient, Net Sales shall be adjusted by multiplying actual Net Sales of such Combination Product by the fraction A/C, where C is the standard sales price in that country of that Combination Product; or (ii) B is known but a Product containing the same amount of such Collaboration Antibody(s) is not sold separately in that country, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction C-B/C. If, in a specific country, A and B are not known, the allocation of Net Sales for such Combination Product shall be negotiated by the Parties in good faith.

15.6 Royalty Term. A Party’s obligation to pay royalties shall commence, on a country-by-country basis, with respect to each separate Product, on the date of First Commercial Sale of such Product in such country. The obligation shall expire, on a country-by-country basis, with respect to each separate Product on the latest to occur of: [***]

Page 96

In the event that in any country in Europe the Collaboration Patent or CAT Patent is not filed in separate countries, but is filed as a pan-European Patent, the relevant Patent for the purposes of this Clause 15.6 shall be the pan-European Patent.

Upon termination of the royalty obligations of a Party under this Clause 15, with respect to a Product in any country, the licence granted to such Party shall become fully paid-up and irrevocable with respect to such country and the Net Sales of such Product in such country shall be excluded from the royalty calculations in this Clause 15 (including the thresholds and ceilings).

15.7 Valid Claim. [***]

15.8 Sales Subject to Royalties.

15.8.1 Sales between AstraZeneca or CAT as the case may be, its Affiliates and Sub-licensees shall not be subject to royalties hereunder. Royalties shall be calculated [***]. Royalties shall be payable only once for any given batch of Products. For the purposes of determining Net Sales, the Product shall be deemed to be sold when invoiced and a “sale” shall not include, and no royalties shall be payable on, transfers by AstraZeneca or CAT, its Affiliates or Sub-licensees of free samples of Products or clinical trial materials containing CDs or other transfers or dispositions for

Page 97

charitable, pre-clinical, clinical or regulatory purposes. No royalties shall be payable on any transfer between the Parties and/or their Affiliates.

15.8.2 The calculation of royalties under this Clause 15 shall be conducted separately for each Product. Thus if a Party sells more than one Product, the royalty rates, the thresholds and ceilings set out in Schedules 15.1 and 15.2 shall apply separately to each Product.

15.9 Royalty Payments. The royalties shall be calculated quarterly as of the last day of March, June, September and December respectively, for the Calendar Quarter ending on that date. Each Party shall pay the royalties in conjunction with the delivery of a written report to the other Party within ninety (90) days after the end of each Calendar Quarter that shows, with respect to each country and each Product, the amount of royalty payable, sales volume and Net Sales during such Calendar Quarter.

15.10 Currency. All payments required under this Agreement shall be made in U.S. Dollars. For the purpose of computing the Net Sales of Products sold in a currency other than U.S. Dollars, such currency shall be converted from local currency to U.S. Dollars by a Party in accordance with the rates of exchange for the relevant month for converting such other currency into U.S. Dollars used by that Party for its quarterly public financial reporting.

15.11 Mode of Payment. All payments due to a Party under this Agreement shall be made in US dollars within the relevant period, or if no period is stipulated, within thirty (30) days of receipt of the relevant invoice. Payments shall be made by electronic wire transfer of immediately available funds directly to the account of AstraZeneca or CAT designated below or to any other account which such Party may specify by written notice.

Bank Account For CAT:

Account Name: Cambridge Antibody Technology Limited

15.12 Interest. Where either AstraZeneca or CAT does not receive payment of any sums properly due and payable to it hereunder within the relevant period, interest shall accrue on the sum due and owing at the Interest rate, calculated on a daily basis, without prejudice to AstraZeneca’s or CAT’s, as applicable, right to receive payment within the relevant period.

15.13 Records Retention; Audit.

15.13.1 Until the [***] anniversary of 31 January of the Calendar Year in which a Product is sold, each Party shall keep or cause to be kept accurate records or books of account in accordance with IAS accounting principles showing the information that is necessary for the accurate determination of the royalties due hereunder with respect to the sale of such Product.

15.13.2 Upon the written request of one Party the other Party shall permit a certified public accountant or a person possessing similar professional status and associated with an independent accounting firm acceptable to the Parties to inspect during regular business hours and no more than once a Calendar Year and going back no more than three (3) years preceding the then current Calendar Year, all or any part of the audited

Page 99

Party’s records and books necessary to check the accuracy of the royalties paid. The accounting firm shall enter into appropriate obligations with the audited Party to treat all information it receives during its inspection in confidence. The accounting firm shall disclose to the auditing Party only whether the royalty reports are correct and details concerning any discrepancies, but no other information shall be disclosed to the auditing Party. The charges of the accounting firm shall be paid by the auditing Party, except that if the royalties have been understated by more than five percent (5%), the charges shall be paid by the audited Party. Any failure by the auditing Party to exercise its right under this Clause 15.13.2 with respect to a Calendar Year shall constitute a waiver by that Party of its right to later object to any payments made by the other Party under this Agreement during such Calendar Year.

15.14 Invoicing. All payments due to a Party under this Agreement shall be invoiced separately and in full. For the purposes of Indirect Tax invoicing there shall be no offset of amounts due from the other Party. For the avoidance of doubt, this includes, but is not restricted to, the circumstances set out in Clauses [***], 9.3 and 14.4.2, which state that the paying Party may be entitled to withhold or credit certain sums from payments otherwise due.

16. Taxes

16.1 General.

If, in accordance with the foregoing, the paying Party withholds any amount, it shall pay to the paid Party the balance when due, make timely payment to the proper taxing authority of the withheld amount, and send to the paid Party proof of such payment within sixty (60) days following that payment.

16.2 Indirect Tax. Notwithstanding anything contained in Clause 16.1, this Clause 16.2 shall apply with respect to value added taxes, sales taxes or other similar taxes (“Indirect Tax”). All Payments are exclusive of Indirect Tax. If any Indirect Tax is chargeable in respect of any Payments, the paying Party shall pay Indirect Tax at the applicable rate in respect of any such Payments following the receipt of a Indirect Tax invoice in the appropriate form issued by the paid Party in respect of those Payments, such Indirect Tax to be payable on the due date of payment of the Payments to which such Indirect Tax relates.

AstraZeneca acknowledges and agrees that the provisions of the XOMA Notice must be included in this Agreement and are hereby included by reference, but the Parties acknowledge and agree AstraZeneca’s sole obligation under this Clause 18.16 shall be to CAT and solely to the extent specified in the XOMA Notice.

18.17 Diagnostic Applications. The Parties acknowledge and agree that it is not their intention within the Alliance to develop or Exploit any Collaboration Antibody or Product as a diagnostic tool other than as a companion diagnostic to a Product. Accordingly:

18.17.1 in the event that a Product is Exploited as a companion diagnostic to a Product, neither Party shall Exploit it in such a way as to undermine the financial value attributable to the therapeutic Product to which the diagnostic Product is a companion; and

18.17.2 in the event that the therapeutic Product to which the diagnostic Product is a companion is not Exploited, both Parties shall be released from the restrictions set out in Clause 10 in relation to the Target with which the Collaboration Antibody contained in the diagnostic Product

Page 113

binds and to which the the Collaboration Antibody contained in the diagnostic Product is directed.

19. Patent Prosecution and Defence

19.1 Prosecution and Maintenance of Collaboration Patents. AstraZeneca shall be solely responsible for the filing, prosecution and maintenance of Collaboration Patents in accordance with the Patent Filing Strategy as may be varied by agreement by patent attorneys acting on behalf of CAT and AstraZeneca and for using reasonable endeavours to prosecute all patent applications forming part of Collaboration Patents to grant in whichever countries AstraZeneca and CAT, in consultation with each other, deem commercially reasonable but not less than those countries listed in the Patent Filing Strategy, including conducting any claims or proceedings relating to them (including but not limited to any interference, reissue or re-examination or opposition or revocation proceedings). AstraZeneca shall in respect of each Joint Discovery Programme make a composition of matter Patent filing in respect of at least the Exclusive CDs identified in the course of such Programme. AstraZeneca shall promptly keep CAT informed of all material developments in relation to the Collaboration Patents including at times prior to such filing occurring and shall, upon CAT’s request, provide CAT with copies of relevant documents related to the filing, prosecution and maintenance of the Collaboration Patents. AstraZeneca shall consider in good faith any reasonable representations made by CAT in relation to the prosecution of the Collaboration Patents when making any submission to a patent office (including the scope of foreign filings) and in the conduct of any proceedings in relation to such Collaboration Patents. In the case of Collaboration Patents covering Target Results the Costs (excluding always Allocable Overhead) of prosecuting and maintaining the same shall be borne equally by the Parties. AstraZeneca shall invoice CAT for its half share of such Costs half-yearly in arrears and CAT shall pay such invoice within thirty (30) days of its date. In all other cases the Costs shall be borne solely by AstraZeneca. In the case where CAT is paying a half share of the Costs, if

Page 114

there is an item of expenditure forecast exceeding [***] AstraZeneca shall seek CAT’s approval to the expenditure before incurring it, not to be unreasonably withheld or delayed.

19.2 Failure to Prosecute Collaboration Patents. In the event that AstraZeneca declines to file or, having filed, declines to further prosecute and maintain any pending Collaboration Patents, AstraZeneca shall provide CAT with written notice thereof. In the case where AstraZeneca has filed but is declining to further prosecute or maintain Collaboration Patents, such notice shall be given at least thirty (30) days prior to the expiration of any official substantive deadline relating to such activities. In any of such circumstances CAT shall have the right to decide that CAT should file, continue to file or prosecute such Collaboration Patents, and, in such case, CAT shall give written notice to AstraZeneca. AstraZeneca shall upon receipt of any such notice from CAT transfer to CAT all its files relating to the relevant Collaboration Patents and execute any documents to transfer control of such filing, prosecution and maintenance to CAT and thereafter CAT shall be responsible for the cost and expense of prosecuting and maintaining such Collaboration Patents.

19.3 Prosecution and Maintenance of CAT Patents. CAT shall at its own cost and expense be solely responsible for the filing, prosecution and maintenance of CAT Patents in accordance with the Patent Filing Strategy as may be varied by agreement by patent attorneys acting on behalf of CAT and AstraZeneca and using reasonable endeavours to prosecute all patent applications forming part of CAT Patents to grant in whichever countries CAT deems commercially reasonable but not less than those countries listed in the Patent Filing Strategy, including the conduct of any claims or proceedings relating to them (including but not limited to any interference, reissue or re-examination or opposition or revocation proceedings). CAT shall keep AstraZeneca promptly informed of all filings made for CAT Patents including sending AstraZeneca a copy of any such filing and otherwise shall keep AstraZeneca informed of all material developments in relation to the CAT Patents and shall, upon

Page 115

AstraZeneca’ request, provide AstraZeneca with copies of relevant documents related to the filing, prosecution and maintenance of the CAT Patents.

19.4 Failure to Prosecute CAT Patents. In the event that CAT declines to file or, having filed, declines to further prosecute and maintain any pending CAT Patents, CAT shall provide AstraZeneca with written notice thereof. In the case where CAT has filed but is declining to further prosecute or maintain CAT Patents, such notice shall be given at least thirty (30) days prior to the expiration of any official substantive deadline relating to such activities. In any of such circumstances AstraZeneca shall have the right to decide that AstraZeneca should file, continue to file or prosecute such CAT Patents and in such case AstraZeneca shall give written notice to CAT. CAT shall upon receipt of any such notice from AstraZeneca transfer to AstraZeneca all its files relating to the relevant CAT Patents and execute any documents to transfer control of such filing, prosecution and maintenance to AstraZeneca and thereafter and thereafter AstraZeneca shall be responsible for the cost and expense of prosecuting and maintaining such CAT Patents.

19.5 Liaison. Notwithstanding any other provision of this Clause 19, the Parties shall cause their patent attorneys to liaise so far as practicable with respect to the filing, prosecution and maintenance of Patents falling within Collaboration Patents and CAT Patents. Each Party shall be responsible for the cost of its own patent attorney incurred pursuant to this Clause 19.5.

19.6 Background Technologies and Improvements to Background Technologies. Each Party shall have the right, at its own cost and sole discretion, to obtain, prosecute and maintain in its own name any Patents or other IP Protection Rights in relation to such Party’s Background Technologies and any Results that constitute Improvements to such Party’s Background Technologies.

Page 116

19.7 Infringements. In the case where either Party believes that an infringement by a Third Party of the Background Technologies or any of the Results may be occurring, such Party shall disclose full details of the potential infringement to the other Party. Each Party shall then promptly and in any event within sixty (60) days have their respective patent counsel (which shall include patent attorneys and legal advisers) analyse the nature of the potential infringement to determine which IP Protection Rights precisely are being infringed and inform the other Party of the conclusions. In the event that:

19.7.1 such analysis by CAT’s patent counsel shows only CAT Background Technologies or CAT Results or both to be infringed the provisions of Clause 19.8 shall apply;

19.7.2 such analysis by AstraZeneca’s patent counsel shows only AstraZeneca Background Technologies, Target Results and/or AstraZeneca Results to be infringed the provisions of Clause 19.9 shall apply; and

19.7.3 such analysis by both CAT’s and AstraZeneca’s patent counsel shows both CAT’s Background Technologies and Target Results and/or AstraZeneca Results to be infringed the provision of Clause 19.10 shall apply.

19.8 Infringements controlled by CAT. In the circumstances of Clause 19.7.1 CAT may, but shall not be obliged to, at its own cost and expense, enforce the IP Protection Rights relating to the CAT Background Technologies and/or CAT Results in accordance with the following:

19.8.1 CAT shall have sole conduct of the claim and any proceedings including any counterclaim for invalidity or unenforceability or any declaratory judgment action and including the right to settle;

19.8.2 If CAT succeeds in any such infringement proceedings whether at trial or by way of settlement, CAT shall be entitled to retain such part of any award of Costs and damages made in such proceedings or

Page 117

settlement sum as is equal to CAT’s Costs of taking the proceedings and: (a) in the case where the infringing product competes with an Alliance Product or an AstraZeneca Product, CAT shall be entitled to retain an amount equivalent to the royalties which would have been payable to CAT on the sum as if the sum was Net Sales and the balance shall be paid to AstraZeneca; (b) in the case where the infringing product competes with a CAT Alliance Product CAT shall be entitled to retain the balance received by CAT less an amount equivalent to the royalties which would have been due to AstraZeneca on the balance as if they were Net Sales which amount shall be paid to AstraZeneca; and (c) in other cases CAT shall be entitled to retain the remainder in addition; and

19.8.3 If CAT fails to take any such proceedings, AstraZeneca may give CAT notice requesting CAT to take such proceedings within thirty (30) days of the date of notice and, if CAT decides not to do so, AstraZeneca shall be entitled to do so at its own cost and expense in which case it shall have sole conduct of any claim or proceedings including any counterclaim for invalidity or unenforceability. CAT shall provide all necessary assistance to AstraZeneca in relation to such proceedings and AstraZeneca shall on demand by CAT indemnify CAT against the Costs of such activity, unless CAT elects to be separately represented (which shall be at CAT’s discretion), in which case such separate representation shall be at CAT’s cost and expense. AstraZeneca shall have sole right to settle such proceedings including any counterclaim for invalidity or unenforceability or declaratory judgment action, provided that does not include a licence under the relevant CAT Results. If AstraZeneca succeeds in any such proceedings it shall be entitled to retain the whole of any award of Costs and damages made or settlement sum paid.

19.9 Infringements Controlled by AstraZeneca. In the circumstances of Clause 19.7.2 AstraZeneca may, but shall not be obliged to, at its own cost and expense, enforce the IP Protection Rights relating to the AstraZeneca

Page 118

Background Technologies, Target Results and/or the AstraZeneca Results in accordance with the following:

19.9.1 AstraZeneca shall have sole conduct of the claim and any proceedings including any counterclaim for invalidity or unenforceability or any declaratory judgment action and including the right to settle. Where AstraZeneca decides to commence proceedings in relation to IP Protection Rights covering Target Results it shall be entitled to require CAT to join AstraZeneca as co-plaintiff. In such case CAT shall provide all necessary assistance to AstraZeneca in relation to any such proceeding provided that AstraZeneca shall on demand by CAT indemnify CAT against the Costs of such activity unless CAT elects to be separately represented (which shall be at CAT’s discretion) in which case such separate representation shall be at CAT’s own cost and expense;

19.9.2 if AstraZeneca succeeds in any such infringement proceedings whether at trial or by way of settlement, AstraZeneca shall be entitled to retain such part of any award of Costs and damages made in such proceedings or settlement sum as is equal to AstraZeneca’s Costs of taking the proceedings and (a) in the case where the infringing product competes with an Alliance Product or an AstraZeneca Product, AstraZeneca shall be entitled to retain the balance received by AstraZeneca less an amount equivalent to the royalties which would have been due to CAT on the balance as if they were Net Sales which amount shall be paid to CAT; (b) in the case where the infringing product competes with a CAT Alliance Product, AstraZeneca shall be entitled to retain an amount equivalent to the royalties which would have been payable to AstraZeneca on the sum as if the sum was Net Sales and the balance shall be paid to CAT; and (c) in other cases AstraZeneca shall be entitled to retain the remainder in addition;

19.9.3 if AstraZeneca fails to take any such proceedings, CAT may give AstraZeneca notice requesting AstraZeneca to take such proceedings within thirty (30) days of the date of notice and if AstraZeneca decides

Page 119

not to do so, unless the infringement is taking place in a Major Market or AstraZeneca informs CAT that AstraZeneca considers in its sole discretion that to take such proceedings would be prejudicial to its litigation strategy in the Major Markets, CAT shall be entitled to do so at its own cost and expense in which case it shall have sole conduct of any claim or proceedings including any counterclaim for invalidity or unenforceability or any declaratory judgment action. AstraZeneca shall provide all necessary assistance to CAT in relation to such proceedings and CAT shall on demand by AstraZeneca indemnify AstraZeneca against the Costs of such activity, unless AstraZeneca elects to be separately represented (which shall be at AstraZeneca’s discretion), in which case such separate representation shall be at AstraZeneca’s cost and expense. CAT shall have sole right to settle such proceedings including any counterclaim for invalidity or unenforceability, provided that such settlement does not include a licence under the relevant AstraZeneca Background Technologies, Target Results and/or AstraZeneca Results. If CAT succeeds in any such proceedings it shall be entitled to retain the whole of any award of Costs and damages made or settlement sum paid.

19.10 Infringements Controlled by Both Parties. In the circumstances of Clause 19.7.3 both Parties shall, unless they agree otherwise, at their joint cost and expense, enforce the IP Protection Rights relating to the CAT Background Technologies and Target Results and/or the AstraZeneca Results in accordance with the following:

19.10.1 they shall jointly appoint a single counsel to have conduct of the claim and any proceedings including any counterclaim for invalidity or unenforceability or declaratory judgment action on their behalf, provided that neither Party shall have the right to settle such proceedings including any counterclaim for invalidity or unenforceability or declaratory judgment action without the consent of the other Party. Within thirty (30) days of the end of each Calendar Quarter each Party shall notify the other of the Costs incurred by it in

Page 120

relation to the claims or proceedings during that Calendar Quarter, and the Party who is shown to have paid less will within thirty (30) days thereafter make a balancing payment to the other Party so that both the Parties have borne the Costs equally; and

19.10.2 if they succeed in any such infringement proceedings whether at trial or by way of settlement, they shall each be entitled to be paid their Costs and they shall then (a) in the case where the infringing product competes with an Alliance Product or an AstraZeneca Product, AstraZeneca shall be entitled to retain the balance received by AstraZeneca less an amount equivalent to the royalties which would have been due to CAT on the balance as if they were Net Sales which amount shall be paid to CAT; and (b) in the case where the infringing product competes with a CAT Alliance Product, AstraZeneca shall be entitled to retain an amount equivalent to the royalties which would have been payable to AstraZeneca on the sum as if the sum was Net Sales and the balance shall be paid to CAT.

Page 133

and employees in full and on demand, from and against any and all Losses incurred by them to the extent resulting from or arising out or in connection with any claims made or suits brought by a Sub-licensee of AstraZeneca or its Affiliates or a Third Party (collectively, “CAT Third Party Claims”) against CAT, its Affiliates or their respective directors, officers or employees: (a) that arise or result from any activity undertaken by AstraZeneca or its Affiliates or Sub-licensees pursuant to this Agreement; or (b) that allege that the claimant has suffered personal injury or death as a result of AstraZeneca or its Affiliates or Sub licensees’ development or Exploitation of any Products, except for any Loss for which CAT has an obligation to indemnify AstraZeneca and its Affiliates pursuant to Clause 23.2.

23.2 Indemnification of AstraZeneca. In addition to any other remedy available to AstraZeneca, subject to Clause 23.7, CAT shall indemnify, defend and hold harmless AstraZeneca, its Affiliates, and its and their respective directors, officers and employees in full and on demand, from and against any and all Losses incurred by them to the extent resulting from or arising out of or in connection with any claims or suits brought by a Sub-licensee of CAT or its Affiliates or Third Party (collectively, “AstraZeneca Third Party Claims”) against AstraZeneca, its Affiliates or their respective directors, officers or employees:

(a) that arise or result from any activity undertaken by CAT or its Affiliates or Sub-licensees pursuant to this Agreement; or

(b) that allege that the claimant has suffered personal injury or death as a result of CAT or its Affiliates or Sub-licensees’ development or Exploitation of any Products,

except for any Loss for which AstraZeneca has an obligation to indemnify AstraZeneca and its Affiliates pursuant to Clause 23.1.

23.3 Notice of Claim. An Indemnified Party shall give the Indemnifying Party prompt written notice of any Loss or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under

Page 134

Clause 23.1 or 23.2 (an “Indemnification Claim Notice”). In no event shall the Indemnifying Party be liable for any Loss that results from any delay in providing the Indemnification Claim Notice. Each Indemnification Claim Notice shall contain a description of the claim and the nature and amount of the Loss claimed (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all correspondence, communications and official documents (including court documents) received in respect of any such Loss. For the avoidance of doubt, all indemnification claims in respect of a Party, its Affiliates or their respective directors, officers, employees and agents (each, an “Indemnitee”) shall be made solely by such Party to this Agreement.

23.4 Indemnification Procedures. The obligations of an Indemnifying Party under this Clause 23 shall be governed by and contingent upon the following:

23.4.1 Assumption of Defence. At its option, the Indemnifying Party may assume the defence of any Third Party Claim (which, for the avoidance of doubt, shall include the conduct of all dealings with such Third Party) by giving written notice to the Indemnified Party within fourteen (14) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defence of a Third Party Claim by the Indemnifying Party shall not be construed as an acknowledgement that the Indemnifying Party is liable to indemnify any Indemnitee in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defences it may assert against any Indemnified Party’s claim for indemnification.

23.4.2 Control of Defence. Upon the assumption of the defence of a Third Party Claim by the Indemnifying Party:

(a) subject to the provisions of Clause 23.4.3, it shall have the right to and shall assume sole control and responsibility for dealing with the Third Party and the Third Party Claim, including the

Page 135

right to settle the claim on any terms the Indemnifying Party chooses, but at all times in accordance with the provisions of Clause 23.4.4;

(b) if it chooses, the Indemnifying Party may appoint as counsel in the defence of the Third Party Claim any law firm or counsel selected by the Indemnifying Party; and

(c) except as expressly provided in Clause 23.4.3, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party or any Indemnitee in connection with the analysis, defence or settlement of the Third Party Claim. In the event that it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend or hold harmless an Indemnitee from and against the Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including lawyers’ fees and costs of suit) and any Losses incurred by the Indemnifying Party in its defence of the Third Party Claim with respect to such Indemnified Party or Indemnitee.

23.4.3 Right to Participate in Defence. Without limiting Clause 23.4, any Indemnitee shall be entitled to participate in, but not control, the defence of a Third Party Claim by having its views regularly solicited by the Indemnifying Party and, where proceedings are commenced, to retain counsel of its choice for such purpose; provided, however, that such retention shall be at the Indemnitee’s own expense unless, (a) the Indemnifying Party has failed to assume the defence and retain counsel in accordance with Clause 23.4.1 (in which case the Indemnified Party shall control the defence), or (b) the interests of the Indemnitee and the Indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both parties under Applicable Law, ethical rules or equitable principles.

Page 136

23.4.4 Settlement. With respect to any Losses relating solely to the payment of money to the Third Party to settle the Third Party Claim and that will not result in the Indemnified Party or the Indemnitee becoming subject to injunctive relief, and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnitee under Clause 23.4.1, the Indemnifying Party shall have the sole right to enter into any such settlement including any consent judgment, on such terms as the Indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses or where the Indemnified Party will be subject to injunctive relief, where the Indemnifying Party has assumed the defence of a Third Party Claim in accordance with Clause 23.4.1, the Indemnifying Party shall have authority to consent to the entry of any judgement, enter into any settlement or otherwise dispose of such Losses, provided that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed).

23.4.5 Non-Assumption of Defence. If the Indemnifying Party chooses not to defend or prosecute any Third Party Claim, the Indemnified Party shall retain control of the defence thereof but no Indemnified Party or Indemnitee shall admit any liability with respect to, or settle, compromise or discharge, any such Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. The Indemnifying Party shall not be liable for any settlement or other disposition of Losses by an Indemnified Party or an Indemnitee under such a Third Party Claim that is reached without the written consent of the Indemnifying Party.

23.4.6 Cooperation. If the Indemnifying Party chooses to defend any Third Party Claim, the Indemnified Party shall, and shall cause each other Indemnitee to, reasonably cooperate in the defence thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in

Page 137

connection therewith. Such cooperation shall include access during normal business hours by the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making the Indemnified Party, the Indemnitees and its and their employees and agents available on a mutually convenient basis to provide additional information and explanation of any records or information provided, and the Indemnifying Party shall reimburse the Indemnified Party for all of its related reasonable out-of-pocket expenses.

23.4.7 Expenses. Except as expressly provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party where it participates in the defence under Clause 23.4.3 or Clause 23.4.5 shall be reimbursed on a quarterly basis by the Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

23.5 Limitation on Damages. Except with respect to Third Party claims under Clauses 23.1 or 23.2, no Party or any of its Affiliates shall be liable for special, indirect, incidental or consequential damages, or for lost profits, milestones or royalties, whether in contract, warranty, negligence, tort, strict liability or otherwise, arising out of (a) the development or Exploitation of any Product hereunder, or (b) any breach of or failure to perform any of the provisions of this Agreement.

23.6 Insurance. Each Party shall have and maintain such type and amounts of liability insurance covering development or Exploitation of CDs and Products as is normal and customary in the pharmaceutical industry generally for Persons similarly situated, and shall upon request provide the other Party with a copy of its policies of insurance in that regard, along with any amendments and revisions thereto. Notwithstanding the foregoing, at a minimum, CAT shall maintain during any period in which

Page 138

CAT is Exploiting a Product or otherwise has indemnification obligations to AstraZeneca, which indemnification obligations shall be scheduled in the policies (a) commercial general liability insurance with a combined single limit for bodily injury and property damage of not less than U.S.$10 million (b) products liability/completed operations coverage with a minimum indemnity limit of U.S.$5 million per occurrence, and (c) an all-risks insurance policy covering its facilities with a minimum indemnity limit of U.S.$5 million per occurrence. Such policies shall (x) be provided by insurance carrier(s) reasonably acceptable to AstraZeneca, (y) and be written on an a claims made basis. Such policies shall remain in effect throughout the Term and shall not be cancelled or subject to a reduction of coverage without the prior written authorisation of AstraZeneca. Should CAT at any time or for any reason fail to obtain the insurance required herein, or should such insurance be cancelled or the above limits reduced, AstraZeneca shall have the right to procure the same and the cost and expense thereof shall be deducted from any compensation then due or thereafter to become due to CAT under this Agreement.

23.7 Clause 19 to Prevail. In the event of any conflict or overlap between the provisions of this Clause 23 and the provisions of Clause 19, the provisions of Clause 19 shall in all cases prevail.

24. Safety Issues, Adverse Event Reporting and Pharmacovigilence

24.1 Safety Issues concerning Products. The Parties shall keep each other promptly and fully informed as to any safety issues that may come to their attention as a result of any clinical development activities involving a Product. The relevant GPT shall have the right to immediately suspend the relevant clinical development activities with respect to any CD or Product in the event that the GPT, in good faith, reasonably determines based upon available safety data that there exists significant and urgent concerns relating to the safety of patients participating in the relevant clinical studies. The GPT shall immediately notify CAT by telephone upon making such determination, and shall promptly thereafter provide both

Page 139

Parties detailed written notice setting forth the factual basis for its decision, the specific activities being suspended and any other related actions. The GPT shall determine what further actions should be taken with respect to such clinical activities and shall review and amend all relevant Work Plans as necessary to implement such actions. If CAT, in good faith, reasonably determines based upon available safety data that there exists significant and urgent concerns relating to the safety of patients participating in the relevant clinical studies, CAT shall have the right to terminate its participation in the relevant Joint Development Programme or the Final Development of an Alliance Co-Funded Product pursuant to Clauses 7.2 or 9.4.

24.2 Adverse event reporting and Pharmacovigilance. At the time that any CD enters a Development Programme, the Parties will discuss whether to establish procedures between them for adverse event reporting and pharmacovigilance. The Parties will in good faith attempt to establish procedures consistent with requirements of Regulatory Authorities if either Party considers them to be necessary.

25. Term and Termination

25.1 Term. This Agreement shall become effective on the Effective Date and shall continue in full force and effect during the Discovery Term and thereafter for as long as either Party is pursuing pre-clinical or clinical development in respect of one or more CDs or Exploiting Products for which milestones or royalties are owed to a Party pursuant to Clause 15.

25.4.5 Breach Affecting Alliance Product or AstraZeneca Product. In the event of a material breach of any provision of this Agreement other than Clause 11 by AstraZeneca affecting an Alliance Product or an AstraZeneca Product and where such breach is capable of remedy, such breach remains un-remedied for sixty (60) days after notice of such breach (provided that if such breach is capable of remedy but cannot be remedied within such sixty (60) day period, and AstraZeneca commences actions to remedy such breach within such period and thereafter diligently continues such actions, AstraZeneca shall have an additional sixty (60) days to remedy such breach):

(a) where the material breach affects an Alliance Co-Funded Product in Final Development, CAT shall have the right but not the obligation to terminate AstraZeneca’s performance obligations (including any obligations to fund work pursuant to Clause 13) under this Agreement in respect of such Alliance Co-Funded Product and AstraZeneca Abandonment of Alliance

Page 154

Co-Funded Product shall be deemed to have occurred and the provisions of the Handover Schedule relevant to Circumstance 11 shall apply; and

(b) where the material breach affects an AstraZeneca Product or an Alliance Product other than an Alliance Co-Funded Product, CAT shall have the right but not the obligation to require AstraZeneca to commence an out-licence project in respect of such Alliance Product or AstraZeneca Product and CAT shall have the right to make a binding offer, including all of the terms of the relevant licence, pursuant to which CAT would take a licence pursuant to a separate agreement to the relevant AstraZeneca Background Technology and AstraZeneca Results and an assignment of any contract relating solely to the Final Development of the Alliance Product or AstraZeneca Product to allow it to continue the Final Development and Exploitation of the relevant Alliance Product or AstraZeneca Product. [***]

25.5 CAT Change of Control. Upon a Change of Control of CAT plc or CAT in a case where the Person acquiring or merging with CAT plc or CAT is an

Page 155

Affiliate of a pharmaceutical company which at the relevant time has worldwide gross sales during the most recently audited financial period that rank in the top twenty (20) in the world, AstraZeneca shall upon delivery of written notice to CAT at any time within three (3) months after the date of such Change of Control have the following rights (but not the obligation):

25.5.1 if the Change of Control occurs during the Discovery Term, the same rights as under Clause 25.3.2 save that the fee for Clause 25.3.2(c)(i) shall be [***] payable in advance of access and Clause 25.3.2(g) shall not apply;

25.5.2 where Clause 25.5.1 applies, CAT shall be entitled on giving written notice to AstraZeneca within three (3) months of AstraZeneca’s notice under Clause 25.5, to fund [***] of the Programme Costs of the continuing AstraZeneca Discovery Programmes on the terms of Clause 13.3, in which case CAT shall be entitled to receive the milestones and royalties set out in Schedules 14.2 Part B and 15.1 Part B in respect of the development and Exploitation of any Collaboration Antibodies identified in the course of such AstraZeneca Discovery Programme. In the event that CAT does not exercise its right under this Clause 25.5.2, it shall only be entitled to receive the milestones and royalties set out in Schedules 14.2 Part A and 15.1 Part A in respect of the development and Exploitation of any Collaboration Antibodies identified in the course of such AstraZeneca Discovery Programme;

25.5.3 if the Change of Control occurs during the course of any Joint Development Programme, to deem said event as a CAT Abandonment of Joint Development Programme in which case the Handover Schedule provision relating to Circumstance 5 shall apply. CAT shall be entitled on giving written notice to AstraZeneca within three (3) months of the deemed abandonment, to fund [***] of the Programme Costs of the continuing Development Programme which is the subject of this Clause 25.5.3 on the terms of Clause 13.3, in which case CAT shall be entitled to receive the milestones and royalties set out in

Page 156

Schedules 14.2 Part C and 15.1 Part C in respect of the development and Exploitation of any Products developed in the course of such Development Programme. In the event that CAT does not exercise its right under this Clause 25.5.3 it shall only be entitled to receive the milestones and royalties set out in Schedules 14.2 Part B and 15.1 Part B in respect of the development and Exploitation of any Products developed in the course of such Development Programme.

25.5.4 CAT shall cease to have any rights under Clause 3.13.2 to appoint a representative to a GPT;

25.5.5 the provisions of Clause 9.6 shall terminate and any agreement entered into pursuant to Clause 9.6 in respect of any Co-Promotion Product shall terminate in accordance with its own terms; and

25.5.6 save as specified in this Clause 25.5, the provisions of this Agreement shall continue in force as relevant in the circumstances.

25.6 Failure to Make Payment. For the purposes only of Clauses 25.3 and 25.4, failure by a Party at any time to make a payment in full or in part shall not be considered to be a material breach of this Agreement, but this Clause 25.6 shall not prevent the Party not in default from suing the Party in default to recover the sum outstanding together with any interest due pursuant to this Agreement.

25.7 Exclusive Remedy. Except in the event of fraud or fraudulent misrepresentation, the remedies set out in Clauses 25.3.1, 25.3.2, 25.3.3, 25.4.1, 25.4.2, 25.4.3 and 25.4.5 shall, where and to the extent invoked, constitute the exclusive financial remedies of the Parties in the events of default set out in those provisions such that damages, an account of profits and similar remedies are not available in such event.

26. Force Majeure

26.1 In this Agreement, “Force Majeure” means an event which is beyond a non-performing Party’s reasonable control, including an act of God, act of the other Party, strike, lock-out or other industrial/labour dispute (whether

Page 157

involving the workforce of the Party so prevented or of any other Person), war, riot, civil commotion, terrorist act, malicious damage, epidemic, quarantine, fire, flood, storm or natural disaster, whether or not it is later held to be invalid.

26.2 The Force Majeure Party shall, within thirty (30) days of the occurrence of a Force Majeure event, give notice in writing to the other Party specifying the nature and extent of the event of Force Majeure, its anticipated duration and any action being taken to avoid or minimize its effect. Subject to providing such notice, the Force Majeure Party shall not be liable for delay in performance or for non-performance of its obligations under this Agreement, in whole or in part, nor shall the other Party have the right to terminate this Agreement or a Programme, except as otherwise provided in this Agreement, where non-performance or delay in performance has resulted from an event of Force Majeure. The suspension of performance allowed hereunder shall be of no greater scope and no longer duration than is reasonably required.

26.3 The Force Majeure Party shall use reasonable endeavours, without being obligated to incur any expenditure or cost, to bring the Force Majeure event to a close or to find a solution by which this Agreement may be performed despite the continuation of the event of Force Majeure.

26.4 If the Force Majeure Party is prevented from performing its obligations due to a Force Majeure event for a continuous period in excess of sixty (60) days after the date of the occurrence of the Force Majeure event, and such failure to perform would constitute a material breach of this Agreement in the absence of such Force Majeure event, the Parties shall meet and discuss in good faith any amendments to this Agreement to permit the other Party to exercise its rights under this Agreement.

27. Assignment

27.1 Neither Party may assign its rights or, except as provided hereunder, delegate its obligations under this Agreement, whether by operation of law or otherwise, in whole or in part without the prior written consent of the

Page 158

other Party, which consent shall not be unreasonably withheld or delayed, except that: (a) both Parties shall always have the right, without such consent, to perform any or all of its obligations and exercise any or all of its rights under this Agreement through any of its Affiliates; and (b) each of the Parties shall always have the right, on written notice to the other, to assign any or all of its rights and delegate any or all of its obligations hereunder to any of its Affiliates; and (c) CAT shall always have the right on written notice to AstraZeneca, to assign all of its obligations hereunder to an Affiliate, provided that such Affiliate is a successor in interest to all or substantially all of the business to which this Agreement relates; and (d) either Party shall always have the right on written notice to the other Party to assign all of its obligations hereunder to any Third Party successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of the business to which this Agreement relates. Any permitted successor of a Party or any permitted assignee of all of a Party’s rights under this Agreement that has also assumed all of such Party’s obligations hereunder in writing shall, upon any such succession or assignment and assumption, be deemed to be a party to this Agreement as though named herein in substitution for the assigning Party, whereupon the assigning Party shall cease to be a party to this Agreement and shall cease to have any rights or obligations under this Agreement. All validly assigned rights of a Party shall inure to the benefit of and be enforceable by the permitted successors and assigns of such Party. Any attempted assignment or delegation in violation of this Clause 27 shall be void.

27.2 If AstraZeneca assigns this Agreement to a non-UK resident Affiliate, AstraZeneca agrees to indemnify CAT against any withholding tax deducted by the non-UK resident Affiliate, which: (i) CAT is unable to recover despite having taken all reasonable steps to do so; and (ii) is in excess of the amount of withholding tax which would have been deducted by AstraZeneca if the assignment had not taken place; provided always that this indemnity shall not apply if CAT assigns this Agreement to a non-UK resident.

30. Relationship of the Parties

The status of a Party under this Agreement shall be that of an independent contractor. Nothing contained in this Agreement shall be construed as creating a partnership, joint venture or agency relationship between the Parties or, except as otherwise expressly provided in this Agreement, as granting either Party the authority to bind or contract any obligation in the name of or on the account of the other Party or to make any statements, representations, warranties or commitments on behalf of the other Party. All persons employed by a Party shall be employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such Party.

31. Entire Agreement and Severability

31.1 Entire Agreement. This Agreement and the Subscription Agreement constitutes the entire agreement between the Parties with respect to the subject matter of this Agreement. This Agreement supersedes all prior agreements, whether written or oral, with respect to the subject matter of this Agreement including the confidentiality agreement of 5 October 2003, as amended on 13 October 2004. Each Party confirms that it is not relying

Page 161

on any representations, warranties or covenants of the other Party except as specifically set out in this Agreement. Nothing in this Agreement is intended to limit or exclude any liability for fraud. All Schedules and Exhibits referred to in this Agreement are intended to be and are hereby specifically incorporated into and made a part of this Agreement. In the event of any inconsistency between any such Schedules or Exhibits and this Agreement, the terms of this Agreement shall govern.

31.2 Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect, then, to the fullest extent permitted by Applicable Law and if the rights or obligations of any Party will not be materially and adversely affected: (a) such provision will be given no effect by the Parties and shall not form part of this Agreement, (b) all other provisions of this Agreement shall remain in full force and effect, and (c) the Parties shall use their best efforts to negotiate a provision in replacement of the provision held invalid, illegal or unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of the Parties. To the fullest extent permitted by Applicable Law, the Parties waive any provision of law that would render any provision in this Agreement invalid, illegal or unenforceable in any respect.

32. English Language

This Agreement is written and executed in the English language. Any translation into any other language shall not be an official version of this Agreement and in the event of any conflict in interpretation between the English version and such translation, the English version shall prevail.

33. Amendment

Any amendment or modification of this Agreement must be in writing and signed by authorised representatives of both Parties.

Page 162

34. Waiver and Non-Exclusion of Remedies

A Party’s failure to enforce, at any time or for any period of time, any provision of this Agreement, or to exercise any right or remedy shall not constitute a waiver of that provision, right or remedy or prevent such Party from enforcing any or all provisions of this Agreement and exercising any rights or remedies. To be effective any waiver must be in writing. All rights and remedies are cumulative and do not exclude any other right or remedy provided by law or otherwise available.

35. No Benefit to Third Parties

The provisions of this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they shall not be construed as conferring any rights in any other Persons except as otherwise expressly provided in Clause 23. The Contracts (Rights of Third Parties) Act 1999 shall not apply to this Agreement. Except as expressly provided in Clause 23, no Person who is not a party to this Agreement (including any employee, officer, agent, representative or subcontractor of either Party) shall have the right (whether under the Contracts (Rights of Third Parties) Xxx 0000 or otherwise) to enforce any term of this Agreement which expressly or by implication confers a benefit on that Person without the express prior agreement in writing of the Parties, which agreement must refer to this Clause 35.

36. Equitable Relief

The Parties acknowledges and agrees that the restrictions set out in Clauses 10 and 20 are reasonable and necessary to protect the legitimate interests of the other Party and that the Parties would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of Clauses 10 or 20 will result in irreparable injury to a Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of Clauses 10 or 20 the innocent Party shall be authorised and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which the innocent Party may be entitled in law or equity. Nothing in this

Page 163

Clause 36 is intended, or should be construed, to limit a Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement.

37. Further Assurance

Each Party shall perform all further acts and things and execute and deliver such further documents as may be necessary or as the other Party may reasonably require to implement or give effect to this Agreement.

38. Expenses

Except as otherwise expressly provided in this Agreement, each Party shall pay the fees and expenses of its respective lawyers and other experts and all other expenses and costs incurred by such Party incidental to the negotiation, preparation, execution and delivery of this Agreement.

39. Counterparts

This Agreement may be executed in any number of counterparts, each of which shall be deemed an original and all of which taken together shall be deemed to constitute one and the same instrument. An executed signature page of this Agreement delivered by facsimile transmission shall be as effective as an original executed signature page.

40. Guarantee by CAT plc

CAT plc hereby unconditionally and irrevocably guarantees to AstraZeneca the performance of all the financial obligations of CAT under this Agreement, including the due and prompt payment by CAT of any amounts payable under this Agreement and any damages or other financial compensation for breach of this Agreement by CAT or otherwise connected with CAT’s activities under this Agreement (the “Payment Obligations”). In case of the failure of CAT to promptly pay any amounts or to make whole AstraZeneca for any of its obligations under this Agreement, CAT plc hereby agrees to cause the payment of such amounts to be made promptly when and as such amounts become due and payable and as if such amounts were paid by CAT. CAT plc hereby agrees that its obligations hereunder will be absolute and

Page 164

unconditional, irrespective of, and will be unaffected by, the validity, regularity or enforceability of the obligations of CAT under this Agreement, the absence of any action to enforce the same, the dissolution, the insolvency or bankruptcy of CAT or any other circumstance which might otherwise constitute a legal or equitable discharge or defence of a guarantor or surety. CAT plc hereby waives the benefits of diligence, presentment, demand of payment, any requirement that AstraZeneca protect, secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against CAT or any collateral, filing of claims with a court in the event of dissolution, insolvency or bankruptcy of CAT, any right to require a proceeding first against CAT and covenants that its obligations hereunder will not be discharged except by complete payment of the amounts due by CAT under this Agreement. Notwithstanding the foregoing, unless CAT has been legally dissolved, AstraZeneca agrees to give CAT notice of any claim under this Agreement prior to making any demand under this Clause 40 in respect of the Payment Obligations. In the event that any payment to AstraZeneca in respect of any amounts due by CAT under this Agreement is rescinded or must otherwise be returned for any reason whatsoever, CAT will remain liable for such amounts to the extent provided herein as if such amounts had not been paid. The aggregate amount to be paid under this Clause 40 by CAT plc shall be net of any prior payment to AstraZeneca by CAT in respect of such Payment Obligations.

Without limiting the foregoing, such CAT Collaborator may transfer to a Third Party a Licensed Immunoglobulin or Licensed Immunoglobulin Information derived from Licensed Antibody Phage Display Materials under this Agreement. XOMA shall be, and the agreements subject to this Section 2.4 shall provide that XOMA shall be, an intended third party beneficiary with respect to the foregoing provisions. If no Disposition of Transferred Materials is contemplated by such arrangement, then the provisions of this Section 2.4(b) shall not apply. If, however, there is a subsequent Disposition of Transferred Materials to such Third Party, then such Disposition must occur under a written agreement which contains the provisions required by this Section 2.4(b) or the Third party shall not have the benefit of any of the licenses or other rights granted in this Agreement.

(c) The provisions of Sections 2.4(a) and (b) shall not apply to any persons or entities engaged solely in academic, non-commercial activity or who are merely evaluating CAT’s technology and who subsequently do not enter into any written arrangement.

(b) Not later than thirty (30) days after the end of each calendar year, commencing with the first calendar year to commence after the Effective Date, as and to the extent publicly disclosed by CAT (whether in press releases, government filings or otherwise), CAT shall deliver to XOMA written materials pertaining to the current status of activities or compositions of matter as to which CAT claims the right of license hereunder.

(c) CAT shall maintain records fully and properly reflecting those activities covered by this Agreement (including, without limitation, work done with the Licensed Antibody Phage Display Materials) and/or to be reported to XOMA pursuant to this Section 2.5 (the “Records”), in reasonable detail and in good scientific manner for at least three (3) years. Upon the written request of XOMA and not more than once in each calendar year, CAT shall permit an independent consultant appointed by XOMA and reasonably acceptable to CAT and which executes a confidentiality agreement reasonably acceptable to CAT, at XOMA’s expense, to have access during normal business hours to such of the records of CAT as may be reasonably necessary to verify fulfillment of the terms of this Agreement, as well as the accuracy of the reports hereunder. CAT shall verify in writing any statements by CAT personnel as to their accuracy and correctness. The consultant shall not be permitted to see or receive any specific information concerning targets or antibodies of either CAT or any of its collaborators and shall disclose to XOMA only the results and conclusions of its review and the specific details concerning any discrepancies. No other information shall be shared by the consultant without the prior express written consent of CAT unless disclosure is required by law, regulation or judicial order.

2.6 Ownership; Enforcement. At all times XOMA will retain ownership of the XOMA Patent Rights and may use and commercialize such XOMA Patent Rights itself or with any Third Party. XOMA retains the right, at its sole discretion, to enforce, maintain and otherwise protect the XOMA Patent Rights. CAT will reasonably cooperate with XOMA, at XOMA’s expense, with respect to any actions XOMA may choose to take related to the enforcement, maintenance or protection of the XOMA Patent Rights; provided that nothing in the last sentence of this Section 2.6 shall require CAT to breach any contractual obligations to any Third Party.

2.7 Oppositions and/or Appeals to Oppositions. So long as XOMA is in material compliance with its obligations under this Agreement, and subject to any specific contractual obligations of CAT existing on the Effective Date in circumstances constituting, in the reasonable, written opinion of counsel to CAT, a breach thereof, CAT agrees not to enter into any opposition to and/or appeal from any decision by the patent authorities of any country regarding the XOMA Patent Rights and shall not

Page 212

knowingly assist or otherwise cooperate with another party in any such opposition or appeal.

2.8 Release. For consideration set forth herein (including payment in full of the amounts set forth in Section 3.1), the sufficiency of which (once so paid) is hereby acknowledged, XOMA permanently and forever and without further payment or condition releases CAT and its current, former and future parents, subsidiaries, related entities, and their fiduciaries, predecessors, successors, officers, directors, shareholders, agents, employees and permitted assigns and those Third Parties identified upon Schedule 1.4 from any and all claims, causes of action, liabilities, demands, rights of action and/or damages (actual, direct, consequential or otherwise) of any nature and of every kind, known or unknown, suspected or unsuspected, disclosed and undisclosed, as of the Effective Date arising out of and/or based upon or relating in any way to any infringement or alleged infringement of the XOMA Patent Rights (the “Release”); provided, however, that the Release provided for in this Section 2.8 shall extend only to claims, causes of action, liabilities, demands, rights of action and/or damages existing as of the Effective Date and which arose solely out of those activities specified in Schedule 1.4. XOMA acknowledges that it may discover facts different from or in addition to those which it now knows or believes to be true and that the Release shall be and remain effective in all respects notwithstanding such different or additional facts or the discovery thereof. XOMA expressly waives the benefits of any statutory provision or common law rule that provides, in sum or substance, that a release does not extend to claims which the party does not know or suspect to exist in its favor at the time of executing the release, which if known by it, would have materially affected its agreement to release the other party. In particular, but without limitation, XOMA expressly waives the provisions of California Civil Code section 1542, which statute reads:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

Nothing in this Section 2.8 shall be deemed to be a release of any claim, demand or right of action XOMA may now or in the future have against [***] as of the Effective Date or any of their collaborators. The Release shall become irrevocable only upon receipt by XOMA of payment in full by CAT of the amounts set forth in Section 3.1 and shall be revoked in its entirety and null and void ab initio, immediately and without further action of the parties, in the event any such payment by CAT is not received in full by XOMA on or prior to the date on which such amount is due, regardless of any payment received thereafter.

2.9 CAT Covenant Not To Xxx. CAT covenants that it shall not initiate or permit any Third Party over whom it has control to initiate or knowingly assist in any way in the initiation or prosecution of any action asserting any claims, including claims of infringement, under any patents or patent applications under CAT’s control or with

Page 213

respect to which it has the right to xxx against XOMA or any Third Party working with XOMA solely to the extent such claims arise out of XOMA’s activities constituting practice or infringement of any Valid Claim of the XOMA Patent Rights; provided, however, that the covenant contained in this Section 2.9 shall not extend to any claim of a patent or patent application that specifically claims a particular Immunoglobulin or a particular Target.

To receive the benefit of indemnification under Section 6.1, an Indemnified Party must (a) promptly notify CAT in writing of a claim or suit; provided that failure to give such notice shall not relieve CAT of its indemnification obligations except where, and solely to the extent that, such failure actually and materially prejudices the rights of CAT; (b) provide reasonable cooperation (at CAT’s expense); and (c) tender to CAT (and its insurer) full authority to defend or settle the claim or suit; provided that no settlement requiring any admission by the Indemnified Party or that imposes any obligation on the Indemnified Party shall be made without the Indemnified Party’s consent, which consent shall not be unreasonably withheld; and provided, further, that nothing herein shall be deemed to give CAT any right to control any proceeding involving the XOMA Patent Rights or any claim XOMA may bring against any Third Party. CAT shall not have any obligation to indemnify the other party in connection with any settlement made without CAT’s written consent. The Indemnified Party has the right to participate at its own expense, such expense not to be deemed a Liability, in the claim or suit and in selecting counsel therefor. The Indemnified Party shall cooperate with CAT (and its insurer), as reasonably requested.

ARTICLE 7

TERM AND TERMINATION

7.1 Term. Subject to Sections 7.4 and 7.5 hereof, the term of this Agreement will commence on the Effective Date and remain in full force and effect until the expiration of the last patent within the XOMA Patent Rights unless earlier terminated pursuant to Sections 7.2, 7.3 or 7.6.

7.2 Termination Event. This Agreement may be terminated by either CAT or XOMA upon any material breach or default by XOMA or CAT, as the case may be, in the performance of any obligation or condition of this Agreement or if any representation or warranty made by XOMA or CAT, as the case may be, in this Agreement is untrue or materially misleading, in any case effective fifteen (15) days after giving notice to the breaching party of such termination in the case of a payment breach and sixty (60) days after giving written notice to the breaching party of such termination in the case of any other breach, which notice shall describe such breach in reasonable detail. The foregoing notwithstanding, (a) if such breach is cured or shown to be non-existent within the aforesaid fifteen (15) or sixty (60) day period, the notice shall be deemed automatically withdrawn and of no effect and the notifying party shall provide written notice to the breaching party of the withdrawal; (b) no such termination shall be effective so long as the parties are engaged in arbitration under Section 8.13 in connection with such breach or default; and (c) with respect to any person or entity constituting a CAT Collaborator as of the date of such a termination by XOMA, any such termination shall be effective against such CAT Collaborator unless, within forty-five (45) days after written notice from XOMA of such termination, such CAT Collaborator executes a written agreement with XOMA directly obligating such CAT

Page 217

Collaborator to comply with all of the provisions of this Agreement applicable to CAT Collaborators and to fulfill the obligations of CAT (including without limitation any royalty obligations) with respect to any and all Licensed Antibody Phage Display Materials and Licensed Immunoglobulins Disposed of by CAT to such CAT Collaborator as of the date of such termination. Upon any termination by XOMA under this Section 7.2, CAT shall promptly (and in any event not later than forty-five (45) days thereafter) deliver to XOMA a written report specifying as of the date of such termination the information required by Section 2.5(a).

7.3 Termination for Insolvency. If voluntary or involuntary proceedings by or against CAT are instituted in bankruptcy under any insolvency law, or a receiver or custodian is appointed for CAT, or an Insolvency Event occurs in relation to CAT, or substantially all of the assets of CAT are seized or attached and not released within sixty (60) days thereafter, XOMA may immediately terminate this Agreement effective upon notice of such termination.

7.4 Effect of Termination. (a) Termination of this Agreement shall not release any party hereto from any liability which, at the time of such termination, has already accrued to the other party or which is attributable to a period prior to such termination nor preclude either party from pursuing any rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement. It is understood and agreed that monetary damages may not be a sufficient remedy for any breach of this Agreement and that the non-breaching party may be entitled to injunctive relief as a remedy for any such breach. Such remedy shall not be deemed to be the exclusive remedy for any such breach of this Agreement, but shall be in addition to all other remedies available at law or in equity.

(b) Upon any termination of this Agreement, CAT and XOMA shall promptly return to the other party all Confidential Information received from the other party (except that each party may retain one copy for its files solely for the purpose of determining its rights and obligations hereunder).

(c) Except as expressly provided in Section 7.2, all licenses granted under Article 2 hereof shall terminate and be of no further effect upon the termination of this Agreement. No termination of this Agreement shall in and of itself effect the validity of any provision hereof during any period prior thereto or the applicability of any provision hereof to any activities conducted prior thereto.

7.5 Survival. Sections 2.5, 2.6, 2.8, 2.9, [Text intentionally omitted.], 7.2, 7.4, 7.5 and 7.6, and Articles 4, 5, 6 and 8 of this Agreement, shall survive any termination hereof; provided, however, that Section 2.9 shall not survive any termination of this Agreement by CAT pursuant to Section 7.2. Section 2.1 shall survive termination but only as provided in the parenthetical clause of the immediately preceding sentence and as to any Product for which the license hereunder is fully paid up prior to the date of termination in accordance with the third sentence of Section 3.2(a).

7.6 Contested Validity. Except to the extent CAT is compelled to do so by legal process and subject to any specific contractual obligations of CAT existing on the Effective

Page 218

Date in circumstances constituting, in the reasonable, written opinion of counsel to CAT, a breach thereof, if CAT, a CAT Collaborator or any person or entity controlled by any of the foregoing contests, directs another to contest or knowingly assists another in contesting the validity or enforceability of any of the XOMA Patent Rights licensed hereunder, XOMA shall have the right to terminate all of the rights and licenses hereby granted to CAT and any CAT Collaborator under the XOMA Patent Rights; provided, however, that in the event a CAT Collaborator or any person or entity controlled by a CAT Collaborator contests the validity or enforceability of any of the XOMA Patent Rights licensed hereunder other than at the direction, and without the knowing assistance, of CAT, then the foregoing termination right of XOMA shall apply only to the rights hereby granted to such CAT Collaborator; and provided, further, that, in the event of any such termination resulting from activities of CAT, with respect to any person or entity constituting a CAT Collaborator as of the date of such termination, any such termination shall be effective against such CAT Collaborator unless, within forty five (45) days after written notice from XOMA of such termination, such CAT Collaborator executes a written agreement with XOMA directly obligating such CAT Collaborator to comply with all of the provisions of this Agreement applicable to CAT Collaborators and to fulfill the obligations of CAT (including without limitation any royalty obligations) with respect to any and all Licensed Antibody Phage Display Materials and Licensed Immunoglobulins Disposed of by CAT to such CAT Collaborator as of the date of such termination. Upon any termination under this Section 7.6 resulting from activities of CAT, CAT shall promptly (and in any event not later than forty five (45) days thereafter) deliver to XOMA a written report specifying as of the date of such termination the information required by Section 2.5(a).

8.8 Compliance with Laws. In exercising their rights under this license, the parties shall comply in all material respects with the requirements of any and all applicable laws, regulations, rules and orders of any governmental body having jurisdiction over the exercise of rights under this Agreement. CAT shall be responsible, at its expense, for making any required registrations or filings with respect to this Agreement and obtaining any necessary governmental approvals with respect hereto.

8.9 Bankruptcy.

During the term of this Agreement each party shall create and maintain current copies to the extent practicable of all such intellectual property. If a bankruptcy proceeding is commenced by or against one party under Title XI, the other party shall be entitled to a copy of any and all such intellectual property and all embodiments of such intellectual property, and the same, if not in the possession of such other party, shall be promptly delivered to it (a) upon such party’s written request following the commencement of such bankruptcy proceeding, unless the party subject to such bankruptcy proceeding, or its trustee or receiver, elects within thirty (30) days to continue to perform all of its obligations under this Agreement, or (b) if not delivered as provided under clause (a) above, upon such other party’s request following the rejection of this Agreement by or on behalf of the party subject to such bankruptcy proceeding. If a party has taken possession of all applicable embodiments of the intellectual property of the other party pursuant to this Section 8.9 and the trustee in bankruptcy of the other party does not reject this Agreement, the party in possession of such intellectual property shall return such embodiments upon request. If a party seeks or involuntarily is placed under Title XI and the trustee rejects this Agreement as contemplated under 11 U.S.C. 365(n)(1), the other party hereby elects, pursuant to Section 365(n) of Title XI, to retain all rights granted to it under this Agreement to the extent permitted by law.

8.12 Entire Agreement; Amendment.

8.13 Arbitration. (a) Solely with respect to any dispute between the parties to this Agreement (other than any dispute which arises out of or relates to alleged

Page 222

infringement, validity and/or enforceability of the XOMA Patent Rights) upon ten (10) days written notice, any party involved in the dispute may initiate arbitration by giving notice to that effect to the other party or parties involved in the dispute and by filing the notice with the American Arbitration Association or its successor organization (“AAA”) in accordance with its Commercial Arbitration Rules. Such dispute shall then be settled by arbitration in New York, New York, in accordance with the Commercial Arbitration Rules of the AAA or other rules agreed to by the parties involved in the dispute, by a panel of three neutral arbitrators, who shall be selected by the parties involved in the dispute using the procedures for arbitrator selection of the AAA.

(b) The parties acknowledge that this Agreement evidences a transaction involving interstate commerce. Insofar as it applies, the United States Arbitration Act shall govern the interpretation of, enforcement of, and proceedings pursuant to the arbitration clause in this Agreement. Except insofar as the United States Arbitration Act applies to such matters, the agreement to arbitrate set forth in this Section 8.13 shall be construed, and the legal relations among the parties shall be determined in accordance with, the substantive laws of the State of New York.

(c) The panel shall render its decision and award, including a statement of reasons upon which such award is based, within thirty (30) days after the arbitration hearing. The decision of the panel shall be determined by majority vote among the arbitrators, shall be in writing and shall be binding upon the parties involved in the dispute, final and non-appealable. Judgment upon the award rendered by the panel may be entered in any court having jurisdiction thereof in accordance with Section 8.14(a).

(d) Except as provided under the United States Arbitration Act, no action at law or in equity based upon any dispute that is subject to arbitration under this Section 8.13 shall be instituted.

(e) All expenses of any arbitration pursuant to this Section 8.13, including fees and expenses of the parties’ attorneys, fees and expenses of the arbitrators, and fees and expenses of any witness or the cost of any proof produced at the request of the arbitrators, shall be paid by the non-prevailing party.

8.14 Venue; Jurisdiction. (a) Any action or proceeding brought by either party seeking to enforce any provision of, or based on any right arising out of, this Agreement must be brought against any of the parties in the courts of the State of California. Each party (i) hereby irrevocably submits to the jurisdiction of the state courts of the State of California and to the jurisdiction of any United States District Court in the State of California, for the purpose of any suit, action, or other proceeding arising out of or based upon this Agreement or the subject matter hereof brought by any party or its successors or assigns, (ii) hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action, or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action, or proceeding is

Page 223

improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other jurisdiction that may be called upon to grant an enforcement of the judgment of any such California state or federal court.

(b) Process in any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Agreement may be served on any party anywhere in the world. Each party consents to service of process by registered mail at the address to which notices are to be given and further consent that any service of process, writ, judgment or other notice of legal process shall be deemed and held in every respect to be effectively served upon it in connection with proceedings in the State of California, if delivered to CT Corporation System, whose current address is 0000 Xxxxx Xxxxxxxxx, Xxxxx 000, Xxxxxx Xxxxx, XX 00000, which each party irrevocably designates and appoints as its authorized agent for the service of process in the courts in the State of California. Nothing herein shall affect the right of a party to serve process in any other manner permitted by applicable law. Without affecting the validity of process served otherwise pursuant to this Section 8.14(b), XOMA shall simultaneously provide CAT with written notice thereof. Each party further agrees that final judgment against it in any such action or proceeding arising out of or relating to this Agreement shall be conclusive and may be enforced in any other jurisdiction within or outside the United States of America by suit on the judgment, a certified or exemplified copy of which shall be conclusive evidence of the fact and of the amount of its liability.

(c) Each party agrees that it shall not, and that it shall instruct those in its control not to, take any action to frustrate or prevent the enforcement of any writ, decree, final judgment, award (arbitral or otherwise) or order entered against it with respect to this Agreement or the XOMA Patent Rights and shall agree to be bound thereby as if issued or executed by a competent judicial tribunal having personal jurisdiction situated in its country of residence or domicile.

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

Schedule 1.185

XOMA Notice

XOMA owns a number of patents said to cover various aspects of bacterial antibody expression and phage display.

XOMA has licensed these patents on a non-exclusive basis to CAT.

Under the license agreement with XOMA:

• CAT cannot provide phage display services or transfer phage display materials, products or information to you without first showing you a redacted copy of its license from XOMA and this notice.

• If you and CAT enter into a written agreement by which you become a “CAT Collaborator”, then you will be permitted to use phage display services, phage display materials, products and information from CAT to research, develop and commercialise antibody products.

• Collaborators do not, however, have the right to produce commercial quantities of antibodies under the XOMA license. Rather, collaborators only have the right to make research and development quantities of antibodies under that license. Thus, the collaborator may wish to obtain a commercial production license from XOMA (which may be available), or produce commercial quantities of antibodies using another method.

• If you and CAT enter into a written agreement, that agreement must contain the following provisions:

AstraZeneca Press Release

ASTRAZENECA AND CAMBRIDGE ANTIBODY TECHNOLOGY ANNOUNCE MAJOR STRATEGIC ALLIANCE TO DISCOVER AND DEVELOP HUMAN ANTIBODY THERAPEUTICS IN INFLAMMATORY DISORDERS

AstraZeneca makes £75 million upfront equity investment.

Complements earlier alliance with Abgenix, Inc. in oncology.

AstraZeneca today announced a five-year research and development alliance with Cambridge Antibody Technology (CAT) in monoclonal antibody research, principally in inflammatory disorders, including respiratory diseases. AstraZeneca will pay £75 million in cash for an issue of 10,217,983 new ordinary shares in CAT, representing a 19.9 per cent shareholding. The equity subscription requires the approval of CAT shareholders.

The alliance offers an excellent balance and fit between CAT’s established expertise and capabilities in monoclonal antibody generation and optimisation, together with their process technology and early clinical skills, with AstraZeneca’s drug development capabilities and global market strength and representation.

• Both AstraZeneca and CAT will contribute targets to the alliance, which will be co-funded and co-managed by the partners. A minimum of 25 programmes in discovery will be initiated during the five-year duration of the Discovery phase.

Page 250

• Following the completion of the discovery phase, the parties may each elect to continue funding programmes into development. If both parties so elect, the programme will be jointly funded until Clinical Proof of Concept (end of Phase IIb trials), unless either party opts-out earlier. In addition, CAT has the option to continue to fund jointly the development of one in every five products that reach Clinical Proof of Concept up to product launch; in this case CAT would have an option to co-promote such product(s) in the US

• AstraZeneca will receive the rights to opt into, and develop jointly, CAT discovery programmes existing at the commencement of this alliance and also to opt into certain future CAT discovery programmes that CAT may independently initiate. CAT has limited rights to co-promote in the US drugs resulting from these programmes.

• CAT will be principally responsible for antibody discovery, manufacturing process development and the supply of material for exploratory clinical trials. AstraZeneca will be principally responsible for translational biology, clinical development programmes, regulatory filings and commercialisation. Joint teams will be established to oversee the full discovery and development process.

Xxx Xxx XxXxxxxx, Chief Executive of AstraZeneca, said: “I see this alliance with CAT as a major component of AstraZeneca’s strategy to develop new therapeutics for inflammatory and respiratory diseases. Both partners are combining their expertise and making a significant commitment of resources to the alliance”.

Xxxxx Chambré, Chief Executive Officer of CAT, commented “This innovative alliance with a world leader in the field of inflammatory diseases represents a major strategic move by both companies. Not only will it enable CAT to deploy its full range of capabilities and expertise in the early stages of product development, but it will also allow us to enhance our capabilities in the later stages and, for the first time, potentially participate in product commercialisation. Most significantly, CAT will share directly in the successes of products which result from the collaboration and it is therefore an important and exciting opportunity

Page 251

for us to make a significant advance in our transition to a product-based biopharmaceutical company. The creation of this alliance with AstraZeneca is a tribute to their vision in seeing the opportunity for a new model of collaboration between a major pharmaceutical company and a leading biotechnology company.”

Dr Xxxx Xxxxxxxxx, Executive Vice President Product Strategy & Licensing, AstraZeneca, said: “We are delighted to be joining other shareholders in this innovative biopharmaceutical company and are underpinning the closeness of the alliance and strategic importance to both parties by making a significant equity investment in CAT”.

This is the second such research alliance in monoclonal antibodies agreed by AstraZeneca in just over a year. Last October, the company announced a major agreement with Abgenix, Inc. for monoclonal antibody research in oncology.

CHESHIRE AND ARGON ANNOUNCE MAJOR STRATEGIC ALLIANCE TO DISCOVER AND DEVELOP HUMAN ANTIBODY THERAPEUTICS IN INFLAMMATORY DISORDERS

ASTRAZENECA TO TAKE 19.9% EQUITY STAKE IN CAMBRIDGE ANTIBODY TECHNOLOGY

Place, UK … Cambridge Antibody Technology (LSE: CAT; NASDAQ: CATG) and AstraZeneca (LSE:AZN, NASDAQ: AZN) announced today a major strategic alliance for the joint discovery and development of human monoclonal antibody therapeutics, principally in the field of inflammatory disorders, including respiratory diseases. The innovative partnership structure of the alliance reflects each company’s leading position in its respective field and the growing importance of antibodies as therapeutics. The alliance will be co-funded and co-managed by the partners.

The principal terms of the collaboration agreement between the two parties are summarised below:

• The alliance will include a five-year discovery initiation phase during which the partners will jointly initiate a minimum of 25 discovery programmes. The committed joint research investment will be a minimum of $175m during this phase which the parties will fund 50:50. Cambridge Antibody Technology will contribute the greater part of the resource in this discovery phase and expects to commit between 100 and 150 scientists per year to the programme at its peak, most if not all of which will come from existing resources. The principal focus of the discovery programmes will be in inflammatory disorders, however the research may extend to other therapeutic areas.

• Following the completion of the discovery phase the parties may each elect to continue funding programmes into development. If both parties so elect, the programme will be jointly funded until Clinical Proof of Concept (end of Phase IIb trials), unless either party opts-out earlier. In addition, Cambridge Antibody Technology has the option to

Page 255

continue to fund jointly the development of one in every five products that reach Clinical Proof of Concept up to product launch.

• Cambridge Antibody Technology’s financial participation reflects its level of investment in the programme. If Cambridge Antibody Technology opts-out after the discovery phase it receives milestones and royalties. If it opts-out at Clinical Proof of Concept it receives milestones and royalties at a higher level. For those programmes which it funds to product launch it receives higher royalties, sales milestones and an option to co-promote these products in the US. If AstraZeneca opts-out of programmes it receives milestones and royalties.

• AstraZeneca will receive the rights to opt-in to, and develop jointly, Cambridge Antibody Technology discovery programmes existing at the commencement of this alliance and also certain future discovery programmes that Cambridge Antibody Technology may independently initiate. Cambridge Antibody Technology has rights to co-promote in the US products resulting from these programmes.

• Cambridge Antibody Technology will be principally responsible for antibody discovery, manufacturing process development and the supply of material for exploratory clinical trials. AstraZeneca will be principally responsible for translational biology, clinical development programmes, regulatory filings and commercialisation. Joint teams will be established to oversee the full discovery and development process.

• Cambridge Antibody Technology anticipates that its investment in the alliance will be the principal focus of its research investment during the next five years.

• Under a separate Subscription Agreement, AstraZeneca will subscribe in cash for 10,217,983 Cambridge Antibody Technology shares at a price of £7.34per share for a total investment of £75 million. Based on Cambridge Antibody Technology shares in issue as at 21 November 2004 this represents a 19.9% interest in the enlarged issued share capital of Cambridge Antibody Technology. The price represents a 27.3% premium to Cambridge Antibody Technology’s average closing share price for the last 5 business days. The subscription agreement between AstraZeneca and Cambridge Antibody Technology contains certain restrictions on AstraZeneca’s ability to increase its stake or to sell shares.

• The subcription by AstraZeneca requires the disapplication by Cambridge Antibody Technology shareholders of statutory pre-emption rights. A circular convening an

Page 256

Extraordinary General Meeting for this purpose is being posted to Cambridge Antibody Technology shareholders shortly. The alliance is conditional on the completion of the Subscription Agreement.

Xxxxx Chambré, Chief Executive Officer of Cambridge Antibody Technology, commented “This innovative alliance with a world leader in the field of inflammatory diseases represents a major strategic move by both companies. Not only will it enable Cambridge Antibody Technology to deploy its full range of capabilities and expertise in the early stages of product development, but it will also allow us to enhance our capabilities in the later stages and, for the first time, potentially participate in product commercialisation.

• Four Cambridge Antibody Technology human therapeutic antibody products are now at various stages of clinical development, with one further product candidate in pre-clinical development.

• HUMIRA, the leading Cambridge Antibody Technology-derived antibody, isolated and optimised in collaboration with Abbott, has been approved for marketing as a treatment for rheumatoid arthritis in 51 countries. Six further licensed Cambridge Antibody Technology-derived human therapeutic antibodies are in clinical development by licensees, with four further licensed product candidates in pre-clinical development.

• Cambridge Antibody Technology has alliances with a number of pharmaceutical and biotechnology companies to discover, develop and commercialise human monoclonal antibody-based products. In particular, Cambridge Antibody Technology has a broad collaboration with Genzyme for the development and commercialisation of antibodies directed against TGFb, a family of proteins associated with fibrosis and scarring. This collaboration has so far given rise to one antibody product candidate at clinical development stage, and one at pre-clinical development stage.

• Cambridge Antibody Technology has also licensed its proprietary technologies to several companies. CAT’s licensees include: Abbott, Amgen, Chugai, Genzyme, Human Genome Sciences, Merck & Co, Pfizer and Wyeth Research.

• Cambridge Antibody Technology is listed on the London Stock Exchange and on NASDAQ. Cambridge Antibody Technology raised £41m in its IPO in March 1997 and £93m in a secondary offering in March 2000.

AstraZeneca:

• AstraZeneca is a major international healthcare business engaged in the research, development, manufacture and marketing of prescription pharmaceuticals and the supply of healthcare services. It is one of the world’s leading pharmaceutical companies with healthcare sales of over $18.8 billion and leading positions in sales of gastrointestinal, oncology, cardiovascular, neuroscience and respiratory products. AstraZeneca is listed in the Dow Xxxxx Sustainability Index (Global) as well as the FTSE4Good Index.

Antibodies as Therapeutics:

• Around 20% of all biotechnology drugs in development are monoclonal antibodies**

• The sector continues to grow rapidly: monoclonal antibodies are increasingly being regarded as a major category of drugs to treat serious diseases and can have a shorter time to market and

Page 258

higher success rates compared to traditional pharmaceuticals. There is also believed to be a reduced threat from generic competition and the potential for premium pricing.

• Antibody drugs are expected to generate sales in excess of $6 billion in 2005, and it is thought that if 10% of the antibody drugs currently in clinical trials prove successful, total sales could reach $45 billion by 2009* Monoclonal antibodies represent the strongest growth area of in the therapeutic proteins market sector – by 2009, it is forecast that monoclonal antibodies will account for 48% of all sales of therapeutic proteins.* Oncology remains the leading therapy area, although the highest area of growth with be in the area of autoimmune/inflammatory – and is expected to almost equal oncology in 2008.***

• Antibody-based therapeutics act by mimicking and harnessing the body’s own immune system. Monoclonal antibodies are potentially both efficacious and safe drugs with exquisite specificity for their target antigen.

• The great majority of approved monoclonal antibodies that are on the market are chimaeric and humanised monoclonal antibodies, with 17 antibodies approved for commercial sale in one or more commercial territory. There are over 100 antibodies in clinical trial, approximately 50 of which are human monoclonal antibodies.

• Human monoclonal antibodies are, in themselves, unlikely to cause adverse immunological responses in patients; a characteristic which undermined successful development of many murine and chimaeric antibodies in the past.
