6.1.3 If the Regulatory Approval giving rise to the requirement for Nektar to make payments to SFJ pursuant to Section 6.1.1 or 6.1.2 (the “Specified Regulatory Approval”) is an Accelerated Regulatory Approval, and such Accelerated Regulatory Approval is later withdrawn by the FDA for any reason (other than to issue a full Regulatory Approval), then (a) Nektar shall have no obligation to make any additional payments pursuant to Section 6.1.1 or 6.1.2, as applicable, during the period after withdrawal of such Accelerated Regulatory Approval and before such time (if ever) as the Specified Regulatory Approval is again obtained (a “Subsequent Regulatory Approval”) and (b) Nektar shall be obligated to use Commercially Reasonable Efforts to (i) resolve any manufacturing issues, if the withdrawal is related to a manufacturing related issue, [***], and (ii) obtain Subsequent Regulatory Approval unless such withdrawal is due to safety or efficacy reasons; provided that in no event shall Nektar be required to conduct any additional clinical study to demonstrate the safety and/or efficacy of the Product following withdrawal by the FDA of such Accelerated Regulatory Approval, except as set forth in clause (i) above. If Subsequent Regulatory Approval is obtained, Nektar’s obligation to make Success Payments shall resume and the due date for payments pursuant to Section 6.1.1 or 6.1.2, as applicable, following such Subsequent Regulatory Approval shall be extended by the number of days between the withdrawal of the Accelerated Regulatory Approval and the applicable Subsequent Regulatory Approval.

ACTIVE/105681617.22

6.2 Payment Adjustments. In the event that the actual Development Costs paid or incurred by SFJ hereunder are lower or greater than One Hundred Fifty Million U.S. Dollars ($150,000,000.00) as of the date of payment of any Success Payment, Approval Buyout Payment or Buy-Out Payment, such payment will be multiplied by a fraction, the numerator of which is equal to the actual amount of Development Costs paid or incurred by SFJ hereunder and the denominator of which is One Hundred Fifty Million U.S. Dollars ($150,000,000.00). In the event that Nektar becomes obligated to make a Success Payment to SFJ while Development Costs are still being paid or incurred, SFJ shall recalculate the applicable adjustment as of the end of each Calendar Year and as of such time as the final amount of actual Development Costs is known and determine any true-up payments required to be made by Nektar with respect to any payment made pursuant to Section 6.1 prior to such time, and Nektar shall pay any such true-up payment to SFJ within thirty (30) days after receipt of invoice from SFJ. For purposes of clarity, in the event that the amount funded by SFJ is less than $150,000,000 as a result of an early termination of the HNC Clinical Trials due to the occurrence of HNC Clinical Trial Futility or Safety Concern, the foregoing pro rata funding provision based on actual SFJ investment shall apply.

6.3 Method and Timing of Payment. The Success Payments to SFJ will be due as of the applicable dates set forth in Sections 6.1.1, 6.1.2 or 6.1.4, as may be adjusted pursuant to Sections 6.1.3 or 6.2, and shall be paid by wire transfer of immediately available funds to an account specified by SFJ from time to time. Nektar will provide SFJ with written notice of each wire transfer to SFJ’s account. All amounts payable and calculations under this Agreement shall be in US dollars.

6.4 Late Payments. If Nektar fails to pay any undisputed amount due under this Agreement on the due date therefore, then, without prejudice to any other remedies that SFJ may have, that amount will bear interest from the due date until payment of such amount is made, both before and after any judgment, [***].

6.5 Taxes.

6.5.1 Notwithstanding anything to the contrary, on or prior to the Effective Date, SFJ shall deliver to Nektar a duly completed and valid (A) IRS Form W-9 certifying that SFJ is a United States person, as such term is defined in Section 7701(a)(30) of the IRC, (B) applicable IRS Form W-8BEN-E claiming treaty benefits under a double taxation treaty with respect to each of “royalties,” “interest” and “other income,” (C) IRS Form W-8IMY to which the forms set forth in the preceding (A) and (B) are attached, or (D) other applicable IRS Form W-8 that indicates no withholding is required in respect of the Product Payments, (in each case ((A) through (D)), the “IRS Withholding Form”), and SFJ shall provide an updated IRS Withholding Form to Nektar throughout the Term whenever required in order for SFJ to have on file a duly completed and valid IRS Withholding Form.

6.5.2 The Parties hereby acknowledge and agree that payments made under this Agreement will be made without reduction for withholding or similar taxes if Nektar, at the time of any such payment, has on file a duly completed and valid IRS Withholding Form in respect of SFJ, unless such withholding or similar tax is required (x) by a taxing authority as a result of an

ACTIVE/105681617.22

audit or examination, (y) due to the assignment of this Agreement or any payment or other obligation or responsibility hereunder (to the extent permitted) by either Party to an Affiliate or Third Party, the re-domiciling of either Party outside the US or any other circumstance that results in either Party no longer being a United States person for U.S. federal income tax purposes, or that results in SFJ no longer being able to provide an IRS Withholding Form, or (z) as a result of a change in Applicable Laws at any time during the Term. In any such case, the Parties shall use commercially reasonable and legal efforts to mitigate the amount of such taxes that would need to be withheld and/or paid. Either Party may request a meeting of the JFC to further discuss any conclusion that a payment should be made with reduction for withholding or similar taxes. Any amounts withheld pursuant to this Section 6.5 will be timely paid over to the appropriate taxing authority, and will be treated for purposes of this Agreement as having been paid to the Party that otherwise would have received such amounts. If a Party (the “Withholding Party”) is required to withhold any taxes on the amounts payable to the other Party (the “Recipient Party”) hereunder as a result of any actions described in clause (y) above by such Withholding Party (or its Affiliates), the Withholding Party shall pay the Recipient Party such additional amounts as are necessary to ensure receipt by the Recipient Party of the full amount which the Recipient Party would have received but for the deduction on account of such withholding. The paying party shall be liable for and shall pay any sales, use, value-added or other similar taxes imposed on payments required to be made hereunder.

6.6 Tax Cooperation. The Parties will cooperate and produce on a timely basis any tax forms or reports, including any IRS Forms W-8BEN or W-9, as applicable, reasonably requested by the other Party in connection with any payment made under this Agreement. Each Party will provide to the other Party any other tax forms that may be reasonably necessary in order for such Party not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will provide, upon request, to the other Party any tax forms at least thirty (30) days prior to the due date for any such payments; provided that the request for such forms was made in a timely manner. Each Party will provide the other with commercially reasonable assistance to enable the recovery, as permitted by law, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT. Each Party will provide commercially reasonable cooperation to the other Party, at the other Party’s expense, in connection with any official or unofficial tax audit or contest relating to tax payments made with respect to amounts paid or payable to such other Party under this Agreement.

6.7 Buy-Out Option.

6.7.1 Approval Buy-Out Option.

6.7.1.1 Within one hundred and eighty (180) days following the Initial Payment Date (in the case of Schedule A Success Payments) or one hundred and eighty (180) days following the Second Regulatory Approval Date (in the case of Schedule B Success Payments), Nektar shall have the right to make a one-time payment (each, an “Approval Buy-Out Payment”) in lieu of all (but not less than all) Schedule A Success Payments or Schedule B Success Payments, as applicable (in each case as adjusted in accordance with

ACTIVE/105681617.22

Section 6.2) (other than the Initial Schedule A Success Payment or Initial Schedule B Success Payment, as applicable, payable pursuant to Section 6.1, in each case, as adjusted in accordance with Section 6.2, which shall remain due and payable if not previously paid) by written notice delivered to SFJ no later than ninety (90) days after the date of the Initial Payment Date or Second Regulatory Approval Date, as applicable, which written notice shall set forth the amount of the applicable Approval Buy-Out Payment, the proposed date of closing (which shall occur within one hundred and eighty (180) days after the Initial Payment Date or Second Regulatory Approval Date, as applicable), and the calculation of the applicable Approval Buy-Out Payment in reasonable detail based upon the proposed closing date. The Approval Buy-Out Payment will be calculated as follows:

Where:

Pi = Success Payments that the Approval Buy-Out Amount applies to, as adjusted in accordance with Section 6.2

r = the Discount Rate

di = payment date per schedule

d1 = closing date of buyout

Each Approval Buy-Out Payment will be payable in one installment in cash at the closing to an account specified by SFJ. The discount rate used to calculate each Approval Buy-Out Payment shall be [***] (the “Discount Rate”). If Nektar elects to make an Approval Buy-Out Payment in lieu of the Schedule A Success Payments, then following such payment Nektar shall no longer be subject to the provision of Section 7.1.

6.7.1.2 In the event that Nektar becomes obligated to make Schedule A Success Payments or Schedule B Payments as a result of an Accelerated Regulatory Approval, then the time period for Nektar to elect to buy out the Schedule A Success Payments or Schedule B Payments, as applicable, shall be extended to the date which is ninety (90) days after such Accelerated Regulatory Approval becomes a full Regulatory Approval, with the applicable Approval Buy-Out Payment to be paid within one hundred eighty (180) days after the date of such full Regulatory Approval.

6.7.2 Change of Control Payment. If a Change of Control is consummated, then within forty-five (45) days following the closing of such Change of Control, Nektar shall pay SFJ an amount in cash equal to one hundred and fifty percent (150%) of actual Development Costs paid or incurred by SFJ hereunder prior to such Change of Control (such payment, the “Change of Control Payment”), provided that no Change of Control Payment shall be payable to SFJ if either (a) the HNC Clinical Trial has been completed but the HNC Clinical Trial Success Criteria was not achieved or (b) HNC Clinical Trial Futility has occurred. The

7.2.2 Regulatory Compliance. Nektar shall not become an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act of 1940, as amended. Nektar shall not become engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). Neither Nektar’s nor any of its Subsidiaries’ properties or assets shall be used by Nektar or any Subsidiary in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Nektar and each of its subsidiaries shall obtain all consents, approvals and authorizations of, make all declarations or filings with, and give all notices to, all Governmental Authorities that are necessary to continue their respective businesses as currently conducted, unless such failure could not reasonably be expected to have a material adverse effect on the Development or Commercialization of the Product.

7.2.3 Protection of Intellectual Property Rights. Nektar shall use Commercially Reasonable Efforts in the exercise of its business judgment to prosecute, protect, defend and maintain the validity and enforceability of the Nektar Intellectual Property.

7.2.4 Acceleration. In the event that, following an applicable Regulatory Approval, (a) Nektar shall fail to make any Success Payment associated with such Regulatory Approval on or before its due date, (b) Nektar has received written notice from SFJ of such failure, specifying in reasonable detail the particulars of such failure, (c) Nektar has not cured such failure [***] following receipt of such notice and (d) the amount of such Success Payment and/or whether such Success Payment is due and payable has not been disputed, all remaining unpaid Success Payments that are based on such Regulatory Approval shall become immediately due and payable; provided that, in the event of any such acceleration, SFJ’s rights to receive such Success Payments, if any, shall be adjusted as set forth in Section 6.2 and reduced by any amounts previously paid to SFJ

7.2.5 Audit Rights. Upon at least [***] and during normal business hours, [***], Nektar may cause an inspection and/or audit by an independent public accounting firm, to be compensated on the basis of time spent and to be reasonably acceptable to SFJ, to be made of the books and records of SFJ and its Affiliates, and the Approved CROs and Approved Vendors with which it contracts, for the [***] purpose of determining the correctness of Development Costs paid and/or incurred under this Agreement. Upon Nektar’s reasonable request not more

ACTIVE/105681617.22

than once in any Calendar Year, SFJ shall use commercially reasonable efforts to exercise any rights it may have under any agreement with a Permitted CRO or a Permitted Vendor to cause an inspection and/or audit by an independent public accounting firm, to be compensated on the basis of time spent, to be made of the books of account of such Permitted CRO or Permitted Vendor for the purpose of determining the correctness of payments made to such Permitted CRO or Permitted Vendor and the correctness of Development Costs paid and/or incurred under this Agreement. All of the expenses of any inspection or audit requested by Nektar hereunder (including the fees and expenses of such independent public accounting firm designated for such purpose) shall be borne by (i) Nektar, if the independent public accounting firm determines that Development Costs were underpaid by an amount less than or equal to [***] of the Development Costs actually paid or (ii) Nektar, if the independent public accounting firm determines that the Development Costs previously paid were incorrect by an amount greater than [***] of the Development Costs actually paid. All information obtained by Nektar as a result of any such inspection or audit shall be Confidential Information subject to Article 9.

behalf of the other Party (each, a “Disclosing Party”) or its Affiliates in connection with this Agreement. The foregoing obligations will not apply to any portion of such information or materials that the Receiving Party can demonstrate:

9.1.1 was publicly disclosed by the Disclosing Party before or after such Confidential Information becomes known to the Receiving Party;

9.1.2 was already known to the Receiving Party or any of its Affiliates, other than under an obligation of confidentiality or non-use, prior to when it was received from the Disclosing Party;

Each Receiving Party may disclose the other Party’s Confidential Information to its Affiliates and its and their Representatives, advisors and independent contractors (including Permitted Third Parties) engaged by such Receiving Party, and with respect to SFJ, the Specified Investors, in each case (a) only to the extent such Persons need to know the Confidential Information solely in connection with the performance of this Agreement or in the case of the Specified Investors, as necessary to monitor and manage its investment in SFJ, and (b) provided that each Person receiving Confidential Information must be bound by obligations of confidentiality and non-use at least as stringent as an equivalent in scope to those set forth in this Article 9 prior to any such disclosure and the Party making such disclosure to such Person shall be liable to the other Party for any breach of such obligations by such disclosee.

returned to the Disclosing Party or destroyed by the Receiving Party, and any Person(s) to whom the Receiving Party disclosed (with such destruction being certified in writing by an authorized officer of the Receiving Party), except (i) to the extent such Confidential Information is necessary to exercise any license and/or rights hereunder that survive such expiration or earlier termination; and (ii) one (1) copy of each document may be retained by the Receiving Party solely to the extent necessary to permit it to comply with any ongoing rights and responsibilities with respect to such Confidential Information.

9.4 Confidential Status of the Agreement. Subject to Section 9.2 and Section 9.5, the terms of this Agreement are deemed to be Confidential Information and will be subject to the confidentiality requirements of this Article 9, with each Party being deemed a Receiving Party for such purposes. The Parties each acknowledge that it will be necessary for Nektar to file this Agreement with the U.S. Securities and Exchange Commission and to make other required public disclosures regarding the terms of this Agreement, and accordingly Nektar shall prepare a confidential treatment request in connection with such filing and provide SFJ a reasonable opportunity to review and comment on such filing as well as on such other required public disclosures and thereafter use Commercially Reasonable Efforts to obtain confidential treatment as to the terms of this Agreement; provided that Nektar shall not be required to provide SFJ the opportunity to review and comment on any disclosure previously reviewed and commented upon by SFJ.

9.5 Publicity. The Parties recognize that following the Effective Date the Parties (either individually or jointly) shall issue mutually agreed press release(s) announcing the execution of this Agreement, and thereafter each Party may from time to time desire to issue additional press releases and make other public statements or disclosures regarding the subject matter of this Agreement, and hereby agree that such additional press releases, public statements and disclosures regarding the terms of this Agreement will be permitted only with the other Party’s written consent (which shall not be unreasonably withheld, conditioned or delayed). Any publication, news release or other public announcement relating to the terms of this Agreement will first be reviewed and approved in writing by both Parties; provided, however, that any disclosure of the minimum information which is required by Applicable Law (including the rules of a securities exchange), as reasonably advised by the disclosing Party’s counsel, may be made without the prior consent of the other Party, although the other Party will be given prompt notice of any such legally required disclosure and to the extent practicable will be provided an opportunity to comment on the proposed disclosure and the disclosing Party will consider in good faith any comments provided by the other Party on such proposed disclosure. For avoidance of doubt, this Section 9.5 shall not restrict Nektar from releasing public statements or disclosures regarding Nektar’s development and Commercialization activities with respect to the Product.

In addition, Nektar shall be and remain the sole and exclusive owner of all right, title and interest in and to all Nektar Intellectual Property arising during the term of this Agreement independent of the conduct of the activities contemplated by this Agreement.

10.1.1.2 Trial Inventions.

(a) Nektar shall be the exclusive and sole owner of, and retain all right, title and interest in and to, all Trial Inventions (which shall constitute Nektar Intellectual Property), regardless of inventorship.

In the case of any individual consultant of SFJ or its Affiliates (excluding SFJ’s and its Affiliates’ Permitted Third Parties), if SFJ is unable to cause such consultant to agree to such assignment obligation despite SFJ’s using Commercially Reasonable Efforts to negotiate such assignment obligation, then SFJ shall inform Nektar of such inabiltiy to cause such consultant to agree to such assignment obligation and at Nektar’s sole discretion either: (A) cause such consultant to grant an exclusive, worldwide, royalty-free, fully-paid, freely-assignable license, with the right to sublicense through multiple tiers, under their rights in such Trial Invention to develop, make, have made, use, sell, have sold, offer for sale and import the Product for any and all uses, except where prohibited by Applicable Law and except in the case of consultants who are employed by governmental, not-for-profit, or public institutions that have standard policies against such an assignment (in which case, SFJ shall use Commercially Reasonable Efforts to obtain a suitable license, or right to obtain such a license); or (B) refrain from using such consultant to conduct activities pursuant to this Agreement.

(c) SFJ shall obtain from each Third Party contractor that SFJ or its Affiliate proposes to engage to conduct activities under or in connection with this Agreement on behalf of SFJ or its Affiliates (i) an assignment, (ii) an exclusive, worldwide, royalty-free, fully-paid, freely-assignable license, with the right to sublicense through multiple tiers, or (iii) a nonexclusive, worldwide, royalty-free, fully-paid, freely-assignable license, with the right to sublicense through multiple tiers ((i) through (iii) in order of preference), to Nektar of any Trial Invention that such Third Party contractor conceives, discovers, develops or otherwise makes in connection with activities conducted relating to this Agreement. The Parties acknowledge that it may not be possible to obtain such assignment or license from any such Third Party contractor with respect to technology of broad applicability to the operation of such Third Party contractor’s business or improvements, or improvements to such Third Party contractor’s own proprietary technology used in the performance of services on behalf of SFJ or its Affiliate, in each case, on acceptable terms or at all, and accordingly, following notice by SFJ to Nektar, the Parties agree that the inability of SFJ or its Affiliate to obtain such assignment or license from a Third Party contractor on acceptable terms or at all shall not constitute a breach of SFJ’s obligations under this Agreement.

10.1.1.3 Trial Data Package. Nektar shall be the sole and exclusive owner of the Trial Data Package including the Research Results included therein. SFJ, for itself and on behalf of its Affiliates, hereby assigns, and shall cause such other Permitted Third Parties to assign (subject to Section 10.1.1.2(c)), to Nektar all its right, title and interest in and to the Trial Data Package, including the Research Results included therein.

SFJ agrees to cooperate fully, to cause its Affiliates to cooperate fully, and to use Commercially Reasonable Efforts to cause its and their respective Permitted Third Parties to cooperate fully with Nektar in the preparation, filing, prosecution and maintenance of Patents Covering Trial Inventions filed by or on behalf of Nektar claiming any Licensed Know-How. Such cooperation includes executing all papers and instruments, or requiring its employees, consultants and Permitted Third Parties, to execute such papers and instruments, so as to (a) effectuate the ownership of Trial Inventions set forth in Section 10.1.1.2(a), including Patents claiming or disclosing Trial Inventions, and (b) enable Nektar to apply for and to prosecute patent applications claiming Trial Inventions in any country.

10.1.1.5 No Other Rights. The delivery or disclosure by or on behalf of Nektar to SFJ of any information or materials hereunder will not be construed to grant SFJ any rights or license to use any Intellectual Property Controlled by Nektar other than as necessary to comply with its obligations hereunder or as expressly set forth herein. Except as otherwise expressly permitted in this Agreement, SFJ may not use, publish or otherwise disclose any Intellectual Property Controlled by Nektar without Nektar’s prior written consent.

10.2 Patent Prosecution. As between SFJ and Nektar, Nektar will have sole and exclusive right to prepare, file, prosecute and maintain all Patents within the Nektar Intellectual Property, including all Patents that cover the Trial Inventions, at its own expense (provided that Nektar shall use Commercially Reasonable Efforts to prosecute and maintain such Patents). At Nektar’s request and expense (for reasonable out-of-pocket expenses), SFJ will reasonably cooperate with Nektar in preparing, filing, prosecuting, and maintaining such Patents.

10.3 Intellectual Property Enforcement.

Nektar will have sole control and responsibility of, and discretion with respect to, such allegations and any related actions and/or litigation.

ACTIVE/105681617.22

10.4 Personally Identifiable Information.

10.4.1 In conducting the Clinical Trials and its other obligations under this Agreement, each Party will comply, and will use Commercially Reasonable Efforts to require each applicable Permitted Third Party of such Party to comply, with Applicable Laws relating to privacy or data protection applicable to such Party or the Clinical Trials being conducted by or on behalf of such Party, including ensuring that all necessary (a) consents from Clinical Investigators, Subjects and any others from whom Personally Identifiable Information will be received are obtained; (b) regulatory notifications are filed in all countries for which Sites have been selected; and (c) approvals are obtained in all countries for which Sites have been selected, prior to collection or transfer of such Personally Identifiable Information.

10.4.2 Each Party will not process, and will use Commercially Reasonable Efforts to require each applicable Permitted Third Party of such Party to not process, any Personally Identifiable Information in a way that is contrary to Applicable Laws or any Informed Consent.

10.4.3 Each Party will use Commercially Reasonable Efforts to maintain, and will use Commercially Reasonable Efforts to require each applicable Permitted Third Party of such Party to maintain, appropriate and sufficient technical and organizational security measures to maintain the confidentiality of Personally Identifiable Information and to protect such data

ARTICLE 11

INDEMNIFICATION AND INSURANCE

11.1 Indemnification by Each Party.

11.1.1 By SFJ. SFJ will indemnify and hold Nektar; its Affiliates and their respective officers, directors, employees and agents (the “Nektar Indemnified Parties”), harmless from any and all Losses arising or resulting from any Claims by a Third Party against any Nektar Indemnified Parties to the extent arising from (a) the gross negligence or willful misconduct of SFJ or any of its Affiliates or any of its or their respective Permitted Third Parties in performing SFJ’s obligations under this Agreement; (b) SFJ’s material breach of this Agreement; (c) any material breach of a Protocol by SFJ, or its Affiliate, or any of its or their respective Permitted Third Parties; except to the extent that any of the foregoing clauses (a) through (c) was caused by (i) the gross negligence or willful misconduct of any Nektar Indemnified Party, or (ii) material breach of this Agreement by Nektar.

11.1.2 By Nektar. Nektar will indemnify and hold SFJ, its Affiliates, SFJ’s investors (including the Specified Investors) and their respective officers, directors, employees and agents (the “SFJ Indemnified Parties”), harmless from any and all Losses arising or resulting from any Claims by a Third Party against any SFJ Indemnified Parties to the extent arising from (a) a Product supplied by Nektar; (b) a physical injury or death of a Subject that is caused by the Subject’s participation in the HNC Clinical Trials whether or not directly attributable to the Product; (c) Nektar’s gross negligence or willful misconduct in performing its obligations under this Agreement; (d) Nektar’s material breach of this Agreement (e) any material breach of a Protocol by Nektar, or its Affiliate, or of its or their respective Permitted Third Parties, (f) actual or alleged infringement of any Third Party’s Intellectual Property by the Product or by either Party in performing its duties or obligations hereunder with respect to the Product; and

ACTIVE/105681617.22

(g) injuries sustained by Subjects in connection with the HNC Clinical Trials or the Melanoma Clinical Trial, including Claims arising prior to the Effective Date based upon physical injury or death of a Subject in connection with the HNC Clinical Trials or the Melanoma Clinical Trial, or from the Commercialization of the Product; except to the extent that any of the foregoing (a) through (g) were caused by (i) the gross negligence or willful misconduct of any SFJ Indemnified Party, or (ii) material breach of this Agreement by, SFJ.

11.2 Indemnification Procedure.

11.2.1 Notice of Claim. A Party believing that it is entitled to indemnification under Section 11.1.1 or 11.1.2 (an “Indemnified Party”) will give prompt written notice (each, an “Indemnification Claim Notice”) to the other Party (the “Indemnifying Party”) upon receipt of notice of the commencement of any Claim for which indemnification may be sought, or if earlier, upon the assertion of any such Claim by a Third Party (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a Claim of a Third Party as provided in this Section 11.2.1 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced as a result of such failure to give notice). Each Indemnification Claim Notice will contain a description of the Claim and the nature and amount of the Loss (to the extent that the nature and amount of such Loss are known at such time). The Indemnified Party will furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses.

11.2.2 Control of Defense. At its option, the Indemnifying Party may assume the defense of any Claim by giving written notice to the Indemnified Party within thirty (30) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Claim by the Indemnifying Party will not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify the Indemnified Party in respect of the Claim, nor will it constitute a waiver by the Indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Claim any legal counsel selected by the Indemnifying Party that is reasonably satisfactory to the Indemnified Party. In the event the Indemnifying Party assumes the defense of a Claim, the Indemnified Party will promptly deliver to the Indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Claim. Should the Indemnifying Party assume the defense of a Claim, the Indemnifying Party will not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of such Claim.

11.2.3 Right to Participate in Defense. Without limiting Section 11.2.2, the Indemnified Party will be entitled to (a) participate in, but not control, the defense of such Claim and to engage counsel of its choice for such purpose; provided, however, that such engagement will be at the Indemnified Party’s own expense unless the engagement thereof has been specifically authorized by the Indemnifying Party in writing, and (b) control its defense of such Claim and to engage counsel of its choice for such purpose, at the expense of the Indemnifying

ACTIVE/105681617.22

Party, if the Indemnifying Party has failed to assume the defense and engage counsel in accordance with Section 11.2.2.

11.2.4 Settlement. With respect to any Losses related solely to payment of money damages in connection with a Claim and that includes a complete and unconditional release of the Indemnified Party, will not result in the Indemnified Party admitting liability, becoming subject to injunctive or other equitable relief that will otherwise adversely affect the business of the Indemnified Party in any manner, and as to which the Indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Claims, where the Indemnifying Party has assumed the defense of the Claim in accordance with Section 11.2.2, the Indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld, conditioned or delayed). The Indemnifying Party will not be liable for any settlement or other disposition of a Loss by the Indemnified Party that is reached without the written consent of the Indemnifying Party (which consent will not be unreasonably withheld, conditioned or delayed). Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party will not admit any liability with respect to, or settle, compromise or discharge, any Claim without the prior written consent of the Indemnifying Party, not to be unreasonably withheld or delayed.

11.2.5 Cooperation. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party will reasonably cooperate in the defense or prosecution thereof and will 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 connection therewith. Such cooperation will include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Claim, and making employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

11.3 Insurance.

11.3.1 Generally. Commencing as of the Effective Date and thereafter during the Development Term, and subject to Section 11.3.2 below, each Party will carry and maintain, at its own expense, insurance coverage of the kind and with liability limits that, at a minimum, satisfy the requirements of Section 11.3.2, to protect itself and the other Party against any claims or liabilities that may arise from the conduct of the HNC Clinical Trials and all other rights and obligations hereunder with insurers with a minimum “A-VII” or better A.M. Best rating. Any deductibles for such insurance policies will be assumed by the insuring Party. Prior to the

ACTIVE/105681617.22

Effective Date, and annually, at each anniversary of the Effective Date (unless, during such year, expiration of the applicable policy occurs first, in which case, on such expiration date), at a Party’s written request the other Party will supply documentation of such insurance coverage via certificates of insurance, if applicable. Each Party shall endeavor to provide the other Party a minimum of thirty (30) days’ notice of cancellation or non-renewal, 10 days for non-payment of premium prior written notice if it is unable to obtain appropriate insurance coverage or if its coverage is canceled, unable to be renewed or changed. For clarity, any insurance coverage or the failure to maintain adequate insurance coverage does not limit or reduce a Party’s liability under this Agreement.

The arbitrators shall have no power or authority, under the AAA’s Commercial Arbitration Rules and procedures or otherwise, to relieve the Parties from their agreement hereunder to arbitrate or otherwise to amend or disregard any provision of this Agreement. The cost of the arbitration, including the fees of the arbitrators and reasonable attorneys’ fees of the prevailing Party, shall be borne by the Party the arbitrator determines has not prevailed in the arbitration.

14.10.2.5 If an arbitral award does not impose an injunction on the losing Party or contain a money damages award in excess of five million dollars ($5,000,000), then the arbitral award shall be final and binding and shall only be subject to such challenges as would otherwise be permissible under the Federal Arbitration Act, 9 U.S.C. § 1 et. seq. Judgment on such an award may be entered in any court of competent jurisdiction and the Parties undertake to carry out the award without delay. In the event that an arbitral award imposes an injunction or contains a monetary award in excess of five million dollars ($5,000,000), the Parties agree that such award may be appealed pursuant to the AAA’s Optional Appellate Arbitration Rules (“Appellate Rules”) and should not be considered to be final and binding until after the time for filing the notice of appeal under the Appellate Rules has expired.
