AZ shall pay the royalties in conjunction with the delivery of a written report to Array within [ * ] after the end of each Calendar Quarter that shows, with respect to each country and each Licensed Product, the sales volume and Net Sales of the Licensed Products during such Calendar Quarter.

6.14 Accounting. AZ shall maintain complete and accurate records, in accordance with the generally accepted accounting practices under which it reports, which are relevant to costs, expenses and payments under this Agreement. Upon the written request of Array, AZ 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 [ * ] and going back no more than [ * ] preceding the current year, all or any part of AZ’s records and books necessary to check the accuracy of such costs, expenses or payments made under this Agreement. The accounting firm shall enter into appropriate obligations with AZ to treat all information it receives during its inspection in confidence. The accounting firm shall disclose to Array and AZ only whether the costs, expenses or payments under this Agreement are correct and details concerning any discrepancies, but no other information shall be disclosed to Array. The Parties agree to settle any discrepancies promptly. The charges of the accounting firm shall be paid by Array, except in the case of a discrepancy against Array of more than [ * ], the charges shall be paid by AZ. Any failure by Array to exercise its right under this Section 6.14 with respect to a Calendar Year within the time period allotted therefor, shall

constitute a waiver by Array of its right to later object to any payments made by AZ under this Agreement during such Calendar Year.

6.15 Credit For Payments for Third Party Licenses.

6.15.1 Reduction of Royalties; Amount. In the event that (i) it becomes reasonably necessary for AZ at its sole discretion to obtain a license under a valid, issued patent of a Third Party, where such patent [ * ] and such patent would necessarily be infringed by [ * ] of such Licensed Product or [ * ] of a Candidate Drug, and (ii) AZ must pay such Third Party for such license a royalty on Net Sales of such Licensed Product in a particular country, AZ may reduce the amount [ * ] on Net Sales of such Licensed Product in such country; provided that the royalties otherwise due to Array on such Net Sales shall not be so reduced [ * ]. AZ shall not be entitled to such credit in any country of the Territory in the event the patents of such Third Party for which such obligations have been incurred are held invalid or unenforceable in that country. Notwithstanding the foregoing, if AZ is required to obtain a license as described in this Section 6.15.1 for [ * ] of a Candidate Drug, and AZ [ * ], then AZ may reduce the amount due to Array [ * ]; provided that [ * ] for any Candidate Drug shall not be so reduced [ * ].

6.15.2 Complementary Technologies. In addition to the foregoing royalty reduction, it is understood that on a case-by-case basis, AZ and Array may agree that it would be in their mutual best interests to in-license a complementary technology for use with a Licensed Product, and in such case may similarly agree that it would be in their mutual best interests to agree upon a further reduction calculated by reference to royalties paid with respect to such in-license; provided, however, that neither Party shall be obligated to agree to any such reduction, and no such reduction shall be made unless so agreed.

6.15.3 Consultation; Disputes. AZ shall consult with Array prior to entering into any license agreement with a Third Party for which AZ would seek to deduct royalties under this Section 6.15, and shall take into account reasonable suggestions of Array with respect to such proposed license. Any dispute under this Section 6.15 including any dispute as to whether such a license is necessary, shall be resolved in accordance with Section 12.2 below.

8.1.6 Should any such comment as provided for under Section 8.1.4 refer to a matter which AZ in its reasonable judgment considers to be of significant importance for the maintenance of the protection which the Array Patents are intended to provide for the Candidate Drugs and/or the Licensed Products, AZ and Array shall discuss in good faith how to maintain such protection.

8.1.7 In the event that Array should decide to permit any pending patent application or any patent included in the Array Patents containing a Valid Claim to lapse by any action, inaction or failure to take any action or to pay any fee when due, Array shall promptly inform AZ of such decision, but no later than two months prior to such action, inaction or failure to pay, provided that such period is available to Array, so that AZ might, at AZ’s expense, seek such patent protection or prevent any such lapse. In such event, Array shall promptly, at the request and expense of AZ, execute and deliver any transfer or assignment or other relevant documents necessary and make all such rightful oaths as will aid or permit AZ to take such actions on its own behalf. Upon such transfer and assignment becoming effective AZ shall immediately assume the responsibility for any costs connected therewith, and such patent application or patent shall immediately be deemed AZ Patents.

However, upon request by AZ in writing to Array, Array shall, for a period of three (3) months from the date of such notice continue at AZ’s cost to be responsible for seeking such patent protection or preventing any such lapse or failure to pay as mentioned in this Section 8.1.7 and contemplated in AZ’s notice.

Where Array wishes to allow a patent application to lapse, and it is not possible for Array to assign its rights to AZ, the patent or patent application will be maintained in the existing name at the expense of AZ and with an exclusive licence to AZ.

At such time as AZ has made all of its Candidate Drug selections, Array’s obligations under this Section shall be limited to those Array Patents containing a Valid Claim.

8.1.8 Should AZ reasonably require Array, [ * ] to seek additional patent protection which AZ in its reasonable judgment considers to be of significant importance for the maintenance of the protection which the Array Patents are intended to provide for the Candidate Drugs and/or Licensed Products, by way of patent registration, patent of importation or revalidation or otherwise, then Array

may do so. Should Array notify AZ in writing that it does not intend to do so, then AZ may do so in its own name or in the name of Array, whichever AZ may elect.

8.1.9 The Parties shall cooperate and shall take each other’s advice into reasonable account in any issue regarding the gaining of patent term extension, including, but not limited to, Supplementary Protection Certificates in the European Economic Area, relating to the Array Patents which AZ in its reasonable judgment considers to be of significant importance for the maintenance of the protection which the Array Patents are intended to provide for the Candidate Drugs and/or the Licensed Products.

8.1.10 Array warrants that it shall not grant any Third Party any right under the Array Patents or otherwise which might contravene or conflict with AZ’s rights under Sections 8.1.2 through 8.1.9. Array further warrants that it shall not grant to any Third Party any right under the Array Patents or otherwise which would mean or have as a consequence that Array would not be entitled to prosecute the Array Patents in a way which would otherwise contravene or conflict with AZ’s rights or Array’s obligations under this Section.

8.1.11 At the commencement of Phase III in respect of ARRY-142886, any Array Patent [ * ] shall be assigned such that it shall be jointly owned by Array and AZ in equal undivided shares. Under any such assignment:

The costs and expenses of the Party bringing suit under this Section shall be borne by such Party, and any damages or other monetary awards recovered shall be shared as follows: The amount of such recovery actually received by the Party controlling such action shall first be applied to the out-of-pocket costs of such action, and then (i) if AZ is the Party that brings such action or proceeding, then Array shall be paid an amount equal to the royalties that would have been due upon sales of the infringing product as if such infringing sales had been Net Sales of a Product sold by AZ, and the remaining portion of such recovery shall be paid to AZ, or (ii) if Array is the Party that brings such action or proceeding, then the remaining portion of such recovery shall be retained by Array. A settlement or consent judgment or other voluntary final disposition of a suit under this Section 8.3.3 may be entered into without the consent of the Party not bringing the suit. Neither Party shall, however, have the right to enter into any settlement or consent to any claim to the effect that the patent protection offered under any part of the Array Patents, the Joint

Patents, the Joint Chemical Patents or the Chemical Patents would be materially negatively affected, without the consent of the other Party, such consent not to be unreasonably withheld.

(d) For any other infringement actions relating to Array Patents containing Valid Claims, Chemical Patents, Joint Patents or Joint Chemical Patents falling outside of the application of Section 8.3.3(a) or 8.3.3(b) Array shall have:

(i) the right to defend or settle such claim or commence an action for infringement against the Third Party, whichever would be applicable, together with

(ii) the right to enforce and collect any judgment thereon;

(iii) subject to Section 8.3.3(d)(v), full control over the conduct of the litigation, including settlement of it. If Array elect to exercise the right to commence an action, then AZ or its Affiliates shall, at Array´s request and at Array’s expense for AZ or its Affiliate’s costs and expenses, assist in the prosecution of such action. Array shall bear its own internal and external legal and other costs and expenses associated with the prosecution of the action;

(iv) AZ or its Affiliates may join the proceedings voluntarily, subject always to Array’s right to decide the conduct over such litigation. Any such joining of the proceedings shall be at AZ’s or its Affiliates’ cost and expense. AZ or its Affiliates shall have the right to independently retain legal counsel and consultants, at its sole cost and expense, but such counsel or consultants shall not have the right to affect Array’s sole management of the prosecution of the action.

(v) Array shall, however, not have the right to enter into any settlement or consent to any claim to the effect that the patent protection offered under any part of the Array Patents or Chemical Patents or Joint Patents or Joint Chemical Patents covering the Candidate Drugs and/or the Licensed Products would be materially negatively affected, without the consent of AZ, such consent not to be unreasonably withheld.

(e) Should Array not take appropriate and diligent action with respect to any infringement by a Third Party as mentioned under Section 8.3.3(d) within one hundred and twenty (120) days after receiving notice of any infringement or possible infringement, or in the case of an ANDA any certificate filed under the ANDA Act within thirty (30) days, then AZ or its Affiliates shall have the right, but not the obligation, to take such action, at its own expense, in its own name, and the right to enforce and collect any judgment thereon.

8.4 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Array or AZ are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the United States Bankruptcy Code. The Parties agree that the Parties, as licensees of such rights

under this Agreement, shall retain and may fully exercise all of their rights and elections under the United States Bankruptcy Code.

Any publication relating to the results of the Research Program or a Phase I or Phase II clinical trial of a Candidate Drug or Licensed Product shall describe such Candidate Drug or Licensed Product by Array compound number (e.g. ARRY-142866) as well as the applicable AZ designation. Each Party shall submit or shall as far as reasonably possible procure that any Third Party carrying out research activities shall submit any proposed publication containing Confidential Information to the other Party at least [ * ] in advance to allow that Party to review such planned public disclosure. The reviewing Party will promptly review such proposed publication and make any objections that it may have to the publication of Confidential Information of the reviewing Party contained therein. Should the reviewing Party make an objection to the publication of any such Confidential Information, then the Parties shall discuss the advantages and disadvantages of publishing such Confidential Information. If the Parties are unable to agree on whether

to publish the same, the Chief Executive Officer of Array and the VP and Global Head of Oncology Research of AZ shall reasonably agree on the extent to which the publication of such Confidential Information shall be made.

ARTICLE XI - TERM AND TERMINATION

11.1 Term. Unless earlier terminated, the Agreement will continue in full force and effect, on a product-by-product and country-by-country basis until the date no further payments are due under Article VI above.

11.2 Termination For Breach. Either Party may terminate this Agreement in the event the other Party shall have materially breached or defaulted in the performance of any of its material obligations hereunder, and such default shall have continued for [ * ] after written notice thereof was provided to the breaching Party by the non-breaching Party provided always that the termination shall not become effective if the breaching Party cures the breach complained about during the [ * ] period (or, if such default cannot be cured within such [ * ] period, if the breaching Party commences actions to cure such default within the notice period and thereafter diligently continues such actions).

11.3 Termination Upon Notice.

11.3.1 AZ’s Notice. AZ may terminate this Agreement upon [ * ] written notice to Array, provided that such notice is given after the end of the Research Term.

11.3.2 Candidate Drug-by-Candidate Drug or Licensed Product-by-Licensed Product. If AZ determines, in its sole discretion, that it is not feasible for AZ to pursue the development, launch or sale of a particular Candidate Drug or Licensed Product in the Territory because [ * ] or due to [ * ], then AZ shall, within [ * ] after such determination is made, notify the Development Committee that it does not intend to continue development or commercialization activities with respect to such Candidate Drug or Licensed Product. If AZ notifies the Development Committee that it does not intend to continue development and/or commercialization activities with respect to a Candidate Drug or Licensed Product, termination of its development and/or commercialization activities with respect to that Candidate Drug or Licensed Product shall be effective:

(a) [ * ] after the date of such notice for a Candidate Drug or Licensed Product which is not being sold in the Territory as at the date of notice, or such shorter period as the Parties may agree; or

(b) [ * ] after the date of such notice for a Licensed Product which is being sold in the Territory as at the date of notice, or such shorter period as the Parties may agree.

In the event AZ decides to terminate development and/or commercialization activities with respect to such Candidate Drug or Licensed Product, such Candidate Drug or Licensed Product shall thereafter be deemed an “Abandoned Product”; provided, however, if the Research Term has ended and as a result of such termination, AZ is not actively performing or planning to perform GLP toxicology studies, or human clinical trials, with respect to any Candidate Drug or Licensed Product, and AZ has notified Array that it does not wish to select any other Candidate Drugs in accordance with Section 2.5.2 or it has no further right to select Candidate Drugs in accordance with Section 2.5.2, and there is no Candidate Drug or Licensed Product being sold in any country within the Territory, then the termination of such Candidate Drug or Licensed Product shall be deemed a termination of this Agreement in its entirety under Section 11.3.1 above.

For the avoidance of doubt, provided that AZ is diligently developing and/or commercializing ARRY-142886 or such other Candidate Drug or Licensed Product as may have been selected in its place, AZ shall be under no obligation to concurrently develop and/or commercialize any other Candidate Drug or Licensed Product. Such undeveloped or un-commercialized Candidate Drug or Licensed Product shall not be deemed an Abandoned Product until AZ has provided formal notice that it intends to terminate development and/or commercialization activities with respect to such Candidate Drug in accordance with this Section 11.3.2.

11.3.3 For each Abandoned Product for which rights revert to Array under this Section 11.3, AZ shall, at Array’s request and cost, take all steps reasonably necessary to enable Array to develop and commercialize the subject Abandoned Product in the Territory, including transferring to Array any MAA or Marketing Approval for such Abandoned Product or other commercially reasonable arrangements as the Parties may agree.

11.3.4 Array Notice. If at any time after the Research Term Array has reasonable grounds to consider that the conditions in Section 11.3.2 above are met (i.e. regardless of whether AZ has formally terminated a particular Licensed Product or Candidate Drug under Section 11.3.2), Array shall notify AZ of such grounds in writing. If AZ fails to remedy such grounds within [ * ] after receipt of written notice Array shall have the right to terminate this Agreement with respect to that particular Licensed Product or Candidate Drug only upon [ * ] written notice to AZ. Any dispute under this Section 11.3.4 shall be subject to resolution under Section 12.2.

11.4 Termination on Bankruptcy. Either Party may terminate this Agreement if, at any time, the other Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of substantially all of its assets, or if the other Party proposes a written agreement of composition or extension of substantially all of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof, or if the other Party shall propose or be a party to any dissolution or liquidation, unless in connection with such dissolution or liquidation this Agreement is assigned under Section 12.4, or if the other Party shall make an assignment of substantially all of its assets for the benefit of creditors.

11.5 Certain Payment Terms.

11.5.1 Wind-Down Payments. In the event of a termination of this Agreement under Section 11.2 by reason of breach by AZ or under Section 11.3, AZ shall meet its own costs of winding down any clinical trials and shall pay to Array an amount of compensation, calculated with reference to: (i) the amount [ * ], if any, over the [ * ] period after the notice of termination under Section 11.3, or over the [ * ] period after the effective date of termination under Section 11.2 (in each case the “Termination Period”) related to matters under the Research Program; (ii) [ * ] in accordance with

Section 3.5; (iii) any non-cancelable commitments incurred by Array hereunder, to the extent such commitments pertained to activities that have been approved by the JRC or Development Committee (excluding any such commitments to the extent reimbursed in clauses (i) or (ii) above). AZ shall make the payments to Array under (i), (ii) and (iii) above [ * ] after the notice of termination is given hereunder and upon receipt of a valid invoice from Array, and upon such payment, AZ shall have no further obligation under Section 6.2 above. In the event there are less than [ * ] remaining under the Research Plan and/or Process Plan in effect on the date the notice of termination is given, such Research Plan and/or Process Plan shall be deemed extended for the remaining months of the Termination Period at the same average monthly amounts as were in effect for the last Research Plan and/or Process Plan approved by the JRC. The Parties shall negotiate in good faith whether to transfer to Array or wind-down the conduct of any ongoing clinical trials. For purposes of this Section 11.5.1, a clinical trial shall be deemed to be an “ongoing clinical trial” if the first patient has been dosed in such clinical trial but such clinical trial was not completed as of the beginning of the Termination Period.

11.5.2 [ * ] Payments. If (i) a termination notice is properly given by AZ pursuant to Section 11.3.1 or 11.3.2, or (ii) a termination has occurred pursuant to Section 11.2 by reason of a breach by Array or pursuant to Section 11.3.4, then AZ [ * ] if the [ * ] or [ * ] occurs after such notice or termination.

11.6 Effect of Termination.

11.6.1 Accrued Rights, Surviving Obligations. Termination, relinquishment or expiration of the Agreement for any reason shall be without prejudice to any obligations which shall have accrued prior to such termination, relinquishment or expiration, including, without limitation, the payment obligations under Article VI hereof and any and all damages arising from any breach hereunder.

11.6.2 Survival. Articles [ * ] shall survive the expiration and any termination of this Agreement; and [ * ] shall survive the expiration but not an earlier termination (except as provided below) of this Agreement.

11.6.3 In addition to Section 11.6.2, the following provisions shall survive termination of this Agreement in the events set forth below:

(a) Certain Terminations. In the event of a termination of this Agreement by AZ pursuant to Section 11.3.1, or termination by Array pursuant to Section 11.2: (i) all Licensed Products and Candidate Drugs then being developed or commercialized by AZ shall be deemed Abandoned Products and (ii) Section 5.3.1 shall survive, and in addition with respect to Licensed Products being sold in the Territory only, Array shall have an irrevocable, exclusive, worldwide license, with the right to grant and authorize sublicenses, under any trademarks owned by AZ and used specifically by AZ to identify the Licensed Products (excluding the AstraZeneca trade name and trade dress) to make, use, sell, import and otherwise exploit the corresponding Abandoned Products. From and after the date of a notice

of termination in the events described in this Section 11.6.3(a), neither Party shall have any further obligations under this Agreement beyond those obligations that survive termination in such events as specified in this Section 11.6.3.

(b) Breach by Array. In the event of a termination of this Agreement by AZ pursuant to Section 11.2:

(i) Array’s obligations under Article VIII and Section 4.2 above shall continue indefinitely and Array’s obligations under Section 4.1 above shall continue for the Exclusivity Period as if the Agreement had not been terminated. In addition, Sections [ * ] shall survive; and

(ii) If such termination occurs prior to the end of the Research Term, AZ shall also have the option to continue the Research and/or the Process Programs with AZ personnel or the personnel of its Affiliates or subcontractors until the earlier of (i) the end of the then-current Research Term plus a period of [ * ], or (ii) selection by AZ of [ * ] Candidate Drugs in addition to ARRY-142886. In the event AZ exercises such option, AZ shall amend the Research Plan to reflect such transfer and the activities to be conducted by AZ thereafter, and Array shall cooperate fully with AZ to provide AZ with all such Collaboration Technology and Array Existing Technology and existing material as is necessary for AZ to identify and select Candidate Drugs. In addition, AZ’s obligation to meet any future FTE payments under Section 6.2.1 shall terminate and AZ shall reimburse Array’s reasonable out-of-pocket costs for such cooperation and provision of technology and material. In addition, during the term set forth in this Section 11.6.3(b)(ii), Array shall develop for use outside the Field only those Compounds (y) that Array has demonstrated do not meet the Candidate Drug Target Profile, and (z) that were determined to meet the Candidate Drug Target Profile in the course of the Research Program prior to the termination, but that were rejected as Candidate Drugs pursuant to Section 2.5.2(a)(ii) above. AZ shall inform Array promptly after it has selected [ * ] Candidate Drugs in addition to ARRY-142886. In addition, licences granted to AZ under Section 5.1 shall survive termination for the duration of the Research Term plus a period of [ * ] thereafter. From and after the date of a notice of termination in the events described in this Section 11.6.3(b), AZ shall have no further obligations under this Agreement (including any AZ payment obligations pursuant to Sections 6.2, 6.3 and 6.4) beyond those obligations that survive termination in such events as specified in this Section 11.6.3(b).

11.7 Termination Not Sole Remedy. Termination is not the sole remedy under this Agreement and, whether or not termination is effected, all other remedies will remain available except as agreed to otherwise herein.

12.6 Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing. The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition. No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver of such condition or term or of another condition or term.

12.7 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible. Such invalidity, illegality or

unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction.

12.8 Force Majeure. 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 disputes (whether involving the workforce of the Party so prevented or of any Third Party), war, riot, civil commotion, terrorist act, malicious damage, epidemic, quarantine, fire, flood, storm, natural disaster or compliance with any law or governmental order, rule, regulation or direction (including changes in the requirements of the Health Authorities), whether or not it is later held to be invalid.

The non-performing party (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 those obligations under this Agreement affected by the event of Force Majeure, in whole or in part, nor shall the other Party have the right to terminate this Agreement, 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.

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

12.9 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.

12.10 Entire Agreement. This Agreement set forth all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto and supersedes and terminates all prior agreements and understanding between the Parties. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as set forth herein. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties hereto unless reduced to writing and signed by the respective authorized officers of the Parties.

12.11 Independent Contractors. Nothing herein shall be construed to create any relationship of employer and employee, agent and principal, partnership or joint venture between the Parties. Each Party is an independent contractor. Neither Party shall assume, either directly or indirectly, any liability of or for the other Party. Neither Party shall have the authority to bind or obligate the other Party and neither Party shall represent that it has such authority.

12.12 Non-Importation. For the avoidance of doubt, the Parties agree that none of the milestones or royalties payable are related directly to the import of Candidate Drugs or other goods supplied by either Party pursuant to this Agreement.

12.13 Patent Marking.

[ * ] FTE’s will be required for synthesis and progression of compounds within the project to the point when [ * ] will be required. These should be located within Array although AstraZeneca may contribute. Research Support Laboratory back-up will initially be required to [ * ] but as the project develops there will be an increased need for [ * ]. These resources would be provided at Array but there is a case when AstraZeneca may need to be involved.

[ * ] is best placed within Array but could be located within the [ * ] in AstraZeneca. FTE’s to support [ * ] could either be located at Array or AstraZeneca. While AstraZeneca runs these many of these [ * ] routinely, these again may be best placed within Array.

[ * ] could be located within Array but since Astrazeneca has such facilities it provides an alternative option. [ * ] are probably best supported from within AstraZeneca as are [ * ] on [ * ] compounds.

Funding of Array FTEs is described in section 2.6. Array and AstraZeneca will ensure appropriate respective allocation of resources between Year One and Year Two in line with the agreed FTE funding and research programme requirements.

Process Plan

Current Status of the ARRY-142886 Processes

The current processes are suitable for [ * ]. It is a [ * ] but the [ * ] for each [ * ] is [ * ]. The overall [ * ] for the synthesis is [ * ]. The processes are [ * ]. [ * ] has been limited to date and a formal study will be carried out with AZ [ * ] on start up of the project.

Process Research and Development Goals and Plans for the Collaboration

[ * ]

There should be sufficient [ * ] available to support [ * ]. Current [ * ] estimates are in the region of [ * ]. As a contingency, further material should be produced [ * ]. This ought to be done at Array, at a time to be agreed [ * ]. Based on current estimates, [ * ], a further [ * ] can be made.

Some [ * ] work will be required to be done in support of [ * ]. This could [ * ] which would need to be [ * ]. As such, subsequent [ * ]. When a decision [ * ] is made, further [ * ] will be carried out by Array.

[ * ]

There is no advantage [ * ]. Laboratory evaluation of [ * ] will be divided between Array and AZ.

Once a [ * ] has been agreed, the [ * ] will need to be [ * ]. This will be done at Array or AZ, depending on [ * ]. Based on [ * ], it is likely that [ * ]. Subsequent to demonstrating [ * ], [ * ] will transfer to AZ.

Timings

Assuming [ * ] it should be possible to [ * ]. Given that [ * ]. The timing of subsequent activities will be dictated by the material requirements of the development plan.

Work on the back-up program and communication with AZ [ * ]

The licensing agreement also covers back ups to ARRY-142886 and therefore [ * ] could [ * ] of the back up compounds. [ * ] would be involved in this [ * ] with subsequent [ * ] following a similar track to the lead compound. Based on [ * ] activities would start in [ * ]. Detailed agreement of logistics of communication for this and the collaboration as a whole will be agreed in [ * ].
