provided, in each case, that if conditional Regulatory Approval in a geographic territory specified above in Section 6.1.1, 6.1.2 or 6.1.3 is obtained on the basis of Successful Phase 3 Interim Analysis but unconditional Regulatory Approval is not obtained (i.e., the accelerated Regulatory Approval is withdrawn by the applicable Regulatory Authority) in such geographic territory as a result of failure of the final results of the Phase 3 Trial to meet the Phase 3 Success Criteria or failure of any other human clinical trial that the applicable Regulatory Authority requires PB to conduct after the grant of conditional Regulatory Approval as a condition to the grant of unconditional Regulatory Approval to meet the primary endpoint(s) of such trial and the Product is required to be withdrawn from the market in such geographic territory, then PB shall have no obligation to make any additional Approval Payment for such geographic territory that would otherwise have become due during the period after withdrawal of such conditional Regulatory Approval and before such time (if ever) as Regulatory Approval for such geographic territory is again obtained (and for so long thereafter as such Regulatory Approval remains in effect), provided further that with regard to withdrawal of such conditional Regulatory Approval in [***].

PB in accordance with Section 4.2.4, or in the event that such actual Development Costs are subject to adjustment pursuant to Section 2.3.3, Section 3.12.2 and/or Section 3.12.3, the Approval Payments will be multiplied by a fraction, the numerator of which is such actual amount of Development Costs paid or incurred by SFJ hereunder (as adjusted, to the extent applicable, pursuant to Section 2.3.3, Section 3.12.2 and/or Section 3.12.3) and the denominator of which is One Hundred Twenty Million U.S. Dollars ($120,000,000.00). In the event that Regulatory Approval is obtained in a particular jurisdiction while Development Costs for other jurisdiction(s) are still being paid or incurred, in which case the Parties shall recalculate the applicable adjustment at such time as the final amount of actual Development Costs is known and determine any true-up payments required to be made by PB with respect to any payment made pursuant to Section 6.1 prior to such time, and PB shall pay any such true-up payment to SFJ within [***] after receipt of invoice from SFJ.

6.3 Method and Timing of Payment. The US Approval Payments, EU Approval Payments and Japan/China Approval Payments to SFJ will be due as of the applicable annual anniversary of the date of the applicable Regulatory Approval. SFJ shall deliver invoices to PB for the US Approval Payments, EU Approval Payments and Japan/China Approval Payments at least [***] before the applicable anniversary of the date of Regulatory Approval, and such payments will be made by PB on or before the later of (a) [***] and (b) [***] following delivery of such invoices, by wire transfer to SFJ's account that SFJ shall designate on such invoice. PB 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 PB fails to pay any 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, at a rate equal to, [***] percent ([***]%) per annum computed on the basis of a year of 360 days for the actual number of days payment is delinquent or if such rate exceeds the maximum amount permitted by Applicable Law, at such maximum rate.

6.5 Taxes. The Parties hereby acknowledge and agree that payments made under this Agreement will be made without reduction for withholding or similar taxes, unless such withholding or similar tax is required (x) by a taxing authority as a result of an audit or examination, (y) due to the assignment of this Agreement or any payment obligation hereunder (to the extent permitted) by SFJ to an Affiliate or Third Party, or (z) as a result of a change in Applicable Laws at any time during the Term. In 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. 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. In the event of a determination within the meaning of Section 1313(a) of the Code that withholding or similar taxes were required but were not properly withheld, the Party that received the relevant payment will indemnify and hold the other Party harmless with respect to such taxes and related Losses.

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 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 to the other Party any tax forms at least [***] prior to the due date for any such payments. 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. Within one hundred and twenty (120) days following the receipt of Regulatory Approval with respect to each of the US, Designated European Countries, and Japan/China, PB 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) Approval Payments (as adjusted in accordance with Section 6.2) for the applicable country(ies) (other than the Initial US Payment, Initial EU Payment or Initial Japan/China Payment, as applicable, payable pursuant to Section 6.1 as a result of such Regulatory Approval, in each case, as adjusted in accordance with Section 6.2) by written notice delivered to SFJ no later than [***] after the date of such Regulatory Approval, which written notice shall set forth the amount of the applicable Approval Buy-Out Payment, the proposed date of closing (which shall occur within [***] after the date of the Regulatory Approval), and the calculation of the Approval Buy-Out Payment in reasonable detail based upon the proposed closing date. The Approval Buy-Out Payment will be calculated as follows:

[***]

Within one hundred and twenty (120) days following the closing of a Change of Control, PB or its successor shall have the right to make a one-time payment (the Change of Control Buy-Out Payment) in lieu of all (but not less than all) remaining Approval Payments for the applicable country(ies) in which Regulatory Approval has been received as of the date of closing of such Change of Control, provided that SFJ has not previously assigned the right to receive the Approval Payments to a Third Party, in which event PB or its successor shall not have such right. To exercise its right to make the Change of Control Buy-Out Payment, PB or its successor shall provide written notice to SFJ (the Change of Control Buy-Out Notice) no later than [***] after the date of closing of such Change of Control, which written notice shall set forth the amount of the applicable Change of

Control Buy-Out Payment, the proposed date of closing of the buy-out (which shall occur within [***] after the date of closing of such Change of Control), and the calculation of the Change of Control Buy-Out Payment in reasonable detail based upon the proposed closing date of the buy-out.

SECURITY INTEREST

7.1 Grant of Security Interest. As security for the payment and performance of the PB Obligations, PB hereby grants to SFJ, effective upon PB's receipt of the Initial Development Cost Payment on the Initial Funding Date, a security interest in all of PB's right, title and interest (excluding any leasehold interest) in, to and under all of its property, wherever located and whether now existing or owned or hereafter acquired or arising, including all goods, accounts (including health-care receivables), equipment, inventory, contract rights or rights to payment of money, leases, license agreements, franchise agreements, general intangibles, intellectual property (including, for the avoidance of doubt, all PB Intellectual Property), commercial tort claims, documents, instruments (including any promissory notes), chattel paper (whether tangible or electronic), cash, deposit accounts, certificates of deposit, fixtures, letters of credit rights (whether or not the letter of credit is evidenced by a writing), securities, and all other investment property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located; and all of PB's books and records relating to the foregoing, and any and all claims, rights and interests in any of the above and all substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing (collectively, the SFJ Collateral). Anything herein to the contrary notwithstanding, in no event shall the SFJ Collateral include, and PB shall not grant and shall not be deemed to have granted a security interest in, (1) any property to the extent that such grant of security interest is prohibited by any Applicable Law of a Governmental Authority or constitutes a breach or default under or results in the termination of or requires any consent not obtained under, any contract, license, agreement, instrument or other document evidencing or giving rise to such property, except to the extent that such Applicable Law or the term in such contract, license, agreement, instrument or other document providing for such prohibition, breach, default or termination or requiring such consent is ineffective under Section 9-406, 9-407, 9-408 or 9- 409 of the Uniform Commercial Code in effect in the State of Delaware (or any successor provision or provisions) of any relevant jurisdiction or any other Applicable Law (including bankruptcy or insolvency statutes) or principles of equity; provided, however, that such security interest shall attach immediately at such time as such Applicable Law

This Agreement shall create a continuing security interest in the SFJ Collateral which shall remain in effect until all PB Obligations (other than contingent indemnity obligations) have been paid or otherwise satisfied in full in accordance with this Agreement and/or, if applicable, the Program Transfer Agreement. Upon payment or other satisfaction of all PB Obligations (other than contingent obligation), SFJ shall, at the sole cost and expense of PB, release its Liens in the SFJ Collateral and all rights therein shall revert to PB.

7.2 Priority of Security Interest. PB represents, warrants and covenants that, subject to fulfilment of PB's obligations under Section 7.4 and SFJ making any filings necessary to achieve such perfection, the security interest granted to SFJ pursuant to this ARTICLE 7 (the SFJ Security Interest) on the Initial Funding Date shall be and shall at all times thereafter continue to be a first- priority perfected security interest in the SFJ Collateral (subject only to the lien of SVB arising under the SVB Loan Agreement, subject in all respects to the terms and conditions of the subordination agreement contemplated by Section 7.4 hereof, and other Permitted Liens that are permitted pursuant to the terms of this Agreement).

Such financing statements may indicate the SFJ Collateral as substantially the same as the SFJ Collateral described in Section 7.1 or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in SFJ's reasonable discretion.

7.4 Subordination to SVB Loan. On or before the Initial Funding Date, PB shall negotiate in good faith and enter into a subordination agreement with SVB and SFJ reflecting in all material respects the terms described on Exhibit P attached hereto, pursuant to which SFJ will subordinate to SVB all PB Obligations and all Liens in the SFJ Collateral in favor of SFJ of indebtedness of PB to SVB, which agreement shall (a) limit the aggregate principal amount of indebtedness of PB to SVB that will be senior to SFJ at [***], (b) include a provision pursuant to which in certain circumstances SFJ shall be entitled in its discretion to purchase or repay all obligations (other than contingent indemnity obligations) owing by PB to SVB arising under or in connection with the SVB Loan Agreement in exchange for a release of SVB's Liens on PB's assets, (c) include an obligation on the part of SFJ to, in connection with any refinancing or

replacement of the SVB Loan Agreement, enter into a new subordination agreement with a new lender(s) on terms and conditions that are taken as a whole not less favorable in any material respect to SFJ than those set forth in the subordination agreement to be entered into with SVB, and (d) otherwise be in form and substance reasonably satisfactory to SFJ. Upon the execution of such new subordination agreement with such new lender(s), references herein to SVB shall refer to such new lender(s), references herein to the SVB Loan shall refer to the loans provided by such new lender (provided that the aggregate principal amount of such loans shall not exceed [***]), references herein to the SVB Collateral shall refer to the collateral securing such new loan, and references herein to the SVB Loan Agreement shall refer to such loan and security agreement or similar document entered into with such new lender(s).

7.5 Negative Covenants.

7.5.1 Incurrence of Certain Indebtedness. PB shall not, without SFJ's prior written consent, create, incur, assume, or be liable for any Indebtedness, or permit any subsidiary of PB to do so, other than Permitted Indebtedness.

7.5.3 Encumbrances. PB shall not, without SFJ's prior written consent:

7.5.3.1 create, incur, allow, or suffer any Lien on any of the PB Intellectual Property, or assign or convey any right to receive income with respect to the PB Intellectual Property (other than royalty and other license fee obligations to licensors thereof in accordance with the applicable license agreement), including the sale of any PB Intellectual Property, or permit any of its subsidiaries to do so, other than Liens in favor of SVB (subject in all respects to the terms and conditions of the subordination agreement contemplated by Section 7.4 hereof) and other Permitted Liens that are permitted pursuant to the terms of this Agreement; or

7.5.3.2 except as and to the extent permitted by Section 7.5.6, enter into any agreement, document, instrument or other arrangement (except with or in favor of SFJ or SVB) with any Person which directly or indirectly prohibits or has the effect of prohibiting PB or any subsidiary of PB from assigning, mortgaging, pledging, granting a security interest in or upon or encumbering any proceeds from PB Intellectual Property.

PB shall not, without SFJ's prior written consent, (a) pay any dividends or make any distribution or payment on account of or redeem, retire or purchase any capital stock, provided that (i) PB may convert any of its equity convertible securities into other equity securities (or cash for partial shares) pursuant to the terms of such equity convertible securities or otherwise in exchange thereof, (ii) PB may pay dividends

7.5.5 Licensing Transactions. PB shall have the right, without SFJ's consent, to enter into any Excluded Licensing Transaction. PB shall not, without SFJ's prior written consent, enter into a Licensing Transaction unless such Licensing Transaction is an Excluded Licensing Transaction (in which case such prohibition shall not apply and no such consent of SFJ shall be required); provided that SFJ shall only be entitled to withhold such consent as to a Licensing Transaction other than an Excluded Licensing Transaction in the event SFJ reasonably determines, and provides PB with written notice of its determination within [***] of PB providing to SFJ a non-binding term sheet or comparable document summarizing the material terms of the proposed Licensing Transaction [***], that PB entering into such Licensing Transaction would [***] (Material Impact).

In the event the arbitrator agrees with PB, PB shall be entitled to enter into the Licensing Transaction; [***], and, [***].

7.5.6 Sales of Royalty Streams. PB shall not sell, transfer or assign, directly or indirectly, in whole or in part, any rights to receive payments of royalties or license fees with respect to the Product or the PB Intellectual Property (including any Accounts with respect to such royalties or license fees), other than to a wholly owned direct or indirect subsidiary of PB (it being understood that the foregoing shall not restrict the creation of any Permitted Lien).

7.5.7 Further Negative Pledges. PB shall not, from and after the Effective Date, enter into any agreement that prohibits or limits the ability of PB to create, incur, assume or suffer to exist any Lien upon any PB Intellectual Property (including any Accounts with respect to such royalties or license fees), whether now owned or hereafter acquired, to secure the PB Obligations, other than (a) agreements with SFJ (including this Agreement), (b) any agreements governing purchase money Liens or capital lease obligations otherwise permitted hereby (in which case, any such prohibition or limitation shall only be effective on the assets financed thereby), (c) customary restrictions on assignment contained in leases, licenses or other

7.6.2 Government Compliance.

7.6.2.1 Maintain its and all its subsidiaries' legal existence and good standing in their respective jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on PB's business or operations, provided that any subsidiary may liquidate or dissolve so long as such liquidation or dissolution would not reasonably be expected to have a material adverse effect on PB's consolidated business or operations, and provided that in connection with such liquidation or dissolution all assets and property of any such subsidiary shall be transferred to PB or another subsidiary of PB.

7.6.5 Acceleration. In the event that, following an applicable Regulatory Approval, PB shall fail to make any Approval Payment associated with such Regulatory Approval within [***] of the due date therefor in accordance with ARTICLE 6, all remaining unpaid Approval 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 Approval Payments, if any, shall be adjusted as set forth in Section 6.2 and reduced by any amounts previously paid to SFJ.

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

Source: PHASEBIO PHARMACEUTICALS INC, 10-K, 3/30/2020





10.1.2 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;

10.2 Authorized Disclosure. Each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary for complying with Applicable Laws, including regulations promulgated by securities exchanges, provided that the Party required to disclose such information promptly notifies the Disclosing Party prior to making any such disclosure and cooperates with the Disclosing Party's efforts to seek confidential treatment or to otherwise limit disclosure. Each Receiving Party may disclose the other Party's Confidential Information to its Affiliates, employees, agents, advisors, and independent contractors (including Permitted Third Parties) engaged by such Receiving Party, 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, if applicable, the Program Transfer Agreement 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 10 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. PB may disclose SFJ Confidential Information to MedImmune as necessary to comply with PB's obligations or exercise PB's rights under the AZ License (it being understood that any such disclosure will be made under the terms of Article 6 of the AZ License and that PB shall not be required to enter into any further confidentiality agreement with MedImmune for such purpose). Each Party may also disclose the material terms of this Agreement (including the form of Program Transfer Agreement) or provide a copy of this Agreement or a summary of such Party's findings during its due diligence investigation of the Products (if applicable) to any bona fide potential or actual investor, investment banker, acquirer, provider of debt or royalty financing, or other potential or actual financial partner without consent of the other Party, and provided that in connection with such disclosure, each disclosee 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 10 prior to any such disclosure and the Party making such disclosure to such disclosee shall be liable to the other Party for any breach of such obligations by such disclosee. Notwithstanding anything in the foregoing to the contrary, Exhibit D constitutes PB's Confidential Information and not SFJ's Confidential Information, and PB may disclose Exhibit D to Third Parties as determined by PB in its sole discretion.

take all reasonable action to avoid unauthorized use or disclosure of Confidential Information of the other Party hereunder.

10.3 Return of Confidential Information. Except as otherwise provided herein, upon expiration or earlier termination of this Agreement, all Confidential Information (including any copies thereof) in written or other tangible form will, at the Disclosing Party's direction, be 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.

The Parties each acknowledge that it will be necessary for PB to file this Agreement with the US Securities and Exchange Commission and to make other required public disclosures regarding the terms of this Agreement, and accordingly PB 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.

10.6 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 10.6 shall not restrict PB from releasing public statements or disclosures regarding PB's development and Commercialization activities with respect to the Product.

(b) SFJ shall cause each employee, individual consultant and Third Party contractor that SFJ or its Affiliate proposes to engage to conduct any Clinical Trial activity under or in connection with this Agreement (including, if applicable, in connection with the Program Transfer Agreement) on its behalf who conceives, discovers, develops or otherwise makes any AstraZeneca Product Improvement under or in connection with activities conducted pursuant to this Agreement to be under an obligation to assign to PB their rights in any such AstraZeneca Product Improvement, so that PB may comply with its obligations with respect to AstraZeneca Improvements, AstraZeneca Product Know-How and AstraZeneca Product Patents under the AZ License. If (i) SFJ is unable to cause any such Third Party contractor or consultant (including any contractor who is, or a consultant who is employed by, a governmental, not-for-profit, or public institution that has standard policies against such an assignment) to agree to such assignment obligation with respect to AstraZeneca Product Improvements despite SFJ's using commercially reasonable efforts to negotiate such assignment obligation, or (ii) Applicable Law would prohibit SFJ from requiring such an assignment from such Third Party contractor or consultant, in each case ((i) and (ii)), SFJ and its Affiliates shall refrain from using such Third Party contractor or consultant to conduct activities pursuant to this Agreement unless PB obtains MedImmune's written consent thereto.

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 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 Applicable Law requires otherwise 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 unless PB obtains MedImmune's written consent thereto.

SFJ Indemnified Party, or (ii) material breach of this Agreement, or, if applicable, the Program Transfer Agreement by, SFJ.

12.2 Indemnification Procedure.

12.2.1 Notice of Claim. A Party believing that it is entitled to indemnification under Section 12.1.1 or 12.1.2 (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 12.2.1 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.

12.2.2 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 [***] 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.

12.2.3 Right to Participate in Defense. Without limiting Section 12.2.2, 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 Party, if the Indemnifying Party has failed to assume the defense and engage counsel in accordance with Section 12.2.2.

12.2.4 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 12.2.2, 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.

12.2.5 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.

12.3 Insurance.

12.3.1 Generally. Commencing as of the Effective Date and thereafter during the Development Term, and subject to Section 12.3.2 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 12.3.2, to protect itself and the other Party against any claims or liabilities that may arise from the conduct of the Clinical Trials and all other rights and obligations hereunder with insurers with a minimum A- A.M. Best rating. Any deductibles for such insurance policies will be assumed by the insuring Party. Such insurance policies will be primary and non-contributing with respect to any other similar insurance policies available to other Party and their Affiliates. Prior to the 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 original certificates of insurance, if applicable.

Each Party will provide the other Party a minimum of [***] prior written notice if it is unable to obtain appropriate insurance coverage or if its coverage is canceled, unable to be renewed or materially 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. Each Party will ensure that no subcontractor, including any Permitted Third Party, will continue to perform the work unless such subcontractor is insured as deemed appropriate by the Party engaging the Permitted Third Party.

12.3.2 Minimum Requirements. Commencing as of the start of the Clinical Trials and thereafter, during the Term (or longer if otherwise stated below), at a minimum, each Party will maintain the following types of insurance coverage at a minimum level that is the greater of (a) the highest minimum level required by Applicable Law in the countries in which the Clinical Trials and other obligations hereunder are being performed or (b) the following (to the extent different).

12.3.2.1 Commercial General Liability: [***] dollars ($[***]) per occurrence; [***] dollars ($[***]) Product and Completed Operations aggregate, including Premises & Operations, Personal Injury, Product and Completed Operations; [***] dollars ($[***]) combined single limit on all owned, non-owned and hired vehicles of such Party.

12.3.2.2 Umbrella Excess Liability: [***] dollars ($[***]) per occurrence.

12.3.2.3 Clinical Trials Liability: [***] dollars ($[***]) per occurrence. PB will obtain such Clinical Trials Liability insurance on a global basis, and, if required, supplemented Clinical Trials Liability Insurance in the US, at its expense and SFJ will obtain supplemental Clinical Trials Liability insurance for the SFJ Territory and on a country specific basis in the European Clinical Trial Countries as required by Applicable Law at its expense, which will be considered Development Costs. Coverage must be maintained for as long as required by Applicable Law in each country after release of the last Subject from the Clinical Trials or where there is no legal requirement at least [***] after the termination of this Agreement.

12.3.2.4 Professional Liability: Any subcontractor, including any Permitted Third Party, who provides professional services to such Party for the Clinical Trials, will obtain Professional Liability Insurance in lieu of Clinical Trial Insurance, with a minimum limit of [***] dollars ($[***]) per occurrence. Coverage must be maintained for at least [***] after the later of (i) expiration or early termination of this Agreement and (ii) release of the last Subject from the Clinical Trials.

12.3.3 Additional Insured. Each Party will include the other Party and its Affiliates as additional insured parties on such Party's Clinical Trial Liability insurance, as set forth in Section 12.3.2.3 for [***] after the later of termination of this Agreement or release of the last Subject from the Clinical Trials.

12.3.4 Product Liability Insurance. Prior to a Program Transfer, PB will be responsible for maintaining product liability insurance related to the Development and

Commercialization of the Product at its expense with SFJ to be named as an additional insured party.

15.10.2.5 If an arbitral award does not impose an injunction on the losing Party or contain a money damages award in excess of [***] dollars USD ($[***]), then the arbitral award shall be final and binding and shall only be subject to such challenges as would otherwise be permissible under the Federal Arbitration Act, 9 U.S.C. § 1 et. seq. . Judgment on such an award may be entered in any court of competent jurisdiction and the Parties undertake to carry out the award without delay. In the event that an arbitral award imposes an injunction or contains a monetary award in excess of [***] dollars USD ($[***]), 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.
