transfer or payment); provided, however, that if any Investor shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Revenue Interest Collateral that, when taken together with all other payments previously made to such Investor hereunder, would be in excess of its Specified Percentage when compared to all payments made to the other Investors hereunder (excluding the cost, if any, to recover such payment), such Investor shall promptly pay over to the other Investors such amounts as shall be necessary to cause such first Investor to share the excess payment ratably with each of the other Investors in accordance with their Specified Percentages.

Section 2.5 Change of Control Payments. The Company shall notify the Investors in writing at least [***] Business Days prior to the occurrence of any Pre-Regulatory Milestone Change of Control or Post-Regulatory Milestone Change of Control during the term of this Agreement.

The Post-Regulatory Milestone Change of Control Price shall be fully creditable towards the Cap Amount.

Section 2.6 No Assumed Obligations, Etc. Notwithstanding any provision in this Agreement to the contrary, no Investor is assuming any liability or obligation of the Company or any other Investor hereunder of whatever nature, whether presently in existence or arising or asserted hereafter.

The Company has sole authority and responsibility for the research, development and Commercialization of the Product.

Section 2.7 Security Interest.

(a) To secure the payment, observance and performance of the Company’s obligations hereunder, the Company hereby grants to the Investors a continuing security interest in all of the Company’s right, title and interest in and to the Revenue Interests, including the accounts, payment intangibles, instruments, chattel paper, check, money and investment property (each, as defined in Article 9 of the UCC) solely to the extent any of the foregoing evidence or constitute the Revenue Interests, and all proceeds thereof, including cash proceeds and noncash proceeds (each, as defined in Article 9 of the UCC), the deposit account described in Section 2.7(b), all funds deposited in or credited to such deposit account, and copies of the books and records of the Company related to the Revenue Interests and such deposit account (all of the foregoing items in which a security interest is granted or purported to be granted, collectively, the “Revenue Interest Collateral”), subject to the provisions of the Subordination Agreement, if any. The Company authorizes the

24

Investors, from and after the Effective Date, to file such financing statements and continuation statements with respect to such financing statements when applicable, in such manner and such jurisdictions as are necessary or appropriate to perfect such security interest. Notwithstanding such authorization, the Company shall ensure, at the Company’s own expense, that the Investors’ security interest in the Revenue Interest Collateral is and remains perfected no later than the Funding Date and at all times thereafter until the termination of this Agreement in accordance with ARTICLE 8. The Company shall provide the Investors written evidence of such perfection, in form and substance satisfactory to the Investors, (x) promptly following the Effective Date, (y) at least 90 days prior to the fifth anniversary of the Effective Date and each fifth anniversary thereafter until the termination of this Agreement in accordance with ARTICLE 8 and (z) at other times upon the reasonable request of any Investor. The provision of such evidence shall be deemed to be a representation and warranty by the Company as of the date such evidence is provided that all actions necessary to perfect the Investors’ security interest in the Revenue Interest Collateral have been taken and that no other creditor has a security interest in the Revenue Interest Collateral except for a Permitted Lien of the type described in clause (a) of the definition thereof and subject to the provisions of the Subordination Agreement, if any. Notwithstanding the foregoing, the Company shall have no obligation to file any amendment to any financing statement to reflect a change in any Investor’s name or address and shall not be deemed to represent and warrant to any such change.

(b) No later than June 30, 2022 (or such later date as the Required Investors may agree in writing), the Company shall, at the Company’s own expense and at all times thereafter until the termination of this Agreement in accordance with ARTICLE 8, (i) establish and maintain a separate deposit account with a financial institution satisfactory to the Required Investors, (ii) cause such deposit account to be and remain subject to an agreement of the type described in Section 9-104(a)(2) of the UCC among the Company, such financial institution and the Investors (or an agent, trustee or representative on their behalf) in form and substance satisfactory to the Required Investors and (iii) deposit, on or prior to each Royalty Payment Date, an amount equal to the Royalty Payment for the applicable calendar quarter in such deposit account; provided, however, that, if at any time the Company’s cash and cash equivalents becomes less than the greater of (x) [***] and (y) [***], the Company shall deposit into such deposit account within two Business Days of such occurrence, and at least monthly thereafter until the termination of this Agreement, an amount of cash equal to the Royalty Payments estimated in good faith by the Company to be payable on the next Royalty Payment Date in respect of the portion of the applicable calendar quarter elapsed prior to such date of determination. The funds on deposit in or credited to such deposit account may be used to make the Royalty Payments to the Investors.

Section 2.8 Mandatory Payment Obligations. The Company’s obligations to pay the True Up Payments, the Event of Default Fee, the Pre-Regulatory Milestone Change of Control Price and the Post-Regulatory Milestone Change of Control Price as they become due under this Agreement shall be absolute. The Company agrees that the True Up Payments, the Event of Default Fee, the Pre-Regulatory Milestone Change of Control Price and the Post-Regulatory Milestone Change of Control Price shall be presumed to be the liquidated damages sustained by each Investor, and the Company agrees that such presumption is reasonable under the circumstances currently existing. The Company expressly waives (to the fullest extent it may lawfully do so) the provisions of any present or future applicable law that prohibits or may prohibit the collection of the True Up Payments, the Event of Default Fee, the Pre-Regulatory Milestone

25

Change of Control Price or the Post-Regulatory Milestone Change of Control Price by the Investors. The Company agrees (to the fullest extent that it may lawfully do so) that (i) each of the True Up Payments, the Event of Default Fee, the Pre-Regulatory Milestone Change of Control Price and the Post-Regulatory Milestone Change of Control Price is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel, (ii) each of the True Up Payments, the Event of Default Fee, the Pre-Regulatory Milestone Change of Control Price and the Post-Regulatory Milestone Change of Control Price shall be payable notwithstanding the then-prevailing market rates at the time payment is made, (iii) there has been a course of conduct between the Investors and the Company giving specific consideration in the transactions contemplated hereby for such agreement to pay the True Up Payments as a charge (and not interest) to the extent they become due, the Event of Default Fee as a charge (and not interest) in the event of an Event of Default, the Pre-Regulatory Milestone Change of Control Price as a charge (and not interest) in the event of a Pre-Regulatory Milestone Change of Control and the Post-Regulatory Milestone Change of Control Price as a charge (and not interest) in the event of a Post-Regulatory Milestone Change of Control and (iv) the Company shall be estopped from claiming differently than as agreed to in this Section 2.8. The Company expressly acknowledges that its agreement to pay each of the True Up Payments, the Event of Default Fee, the Pre-Regulatory Milestone Change of Control Price and the Post-Regulatory Milestone Change of Control Price to the Investors as herein described is on the Effective Date, and will continue to be, a material inducement to each Investor to pay its portion of the Investment Amount.

Upon the Investors’ reasonable request, no more frequently than once per calendar year while any Out-License remains in effect, the Company shall use Commercially Reasonable Efforts to exercise any rights it may have under any Out-License relating to a Product to cause an inspection and/or audit by an independent public accounting firm to be made of the books of account of any counterparty thereto for the purpose of determining the correctness of the calculation of the Royalty Payments under this Agreement.

All of the out-of-pocket expenses of any inspection or audit requested by the Investors hereunder (including the fees and expenses of such independent public accounting firm designated for such purpose) otherwise payable by the Company shall be borne solely by the Investors, unless the independent public accounting firm determines that Royalty Payments previously paid to the Investors during the period of the audit were underpaid by an amount greater than [***] of the Royalty Payments actually paid during such period, in which case such expenses shall be borne by the Company. Any such accounting firm or Company shall not disclose the confidential information of the Company or any such Licensee relating to a Product to the Investors, except to the extent such disclosure is necessary to determine the correctness of Royalty Payments or otherwise would be included in a Royalty Report. All information obtained by the Investors as a result of any such inspection or audit shall be Confidential Information subject to ARTICLE 7. If any audit discloses any underpayments by the Company to the Investors, then such underpayment, together with the late fees contemplated by Section 2.2(b), shall be paid by the Company to the Investors (in accordance with their Specified Percentages in the same manner as provided in Section 2.2(a)) within [***] calendar days of such underpayment being so disclosed.

The Company shall provide the Investors with written notice following (and in any event within [***] Business Days of) becoming aware of a counterparty’s material breach of its obligations under any In-License. The Company shall not terminate (i) any In-License without providing the Investors prior written notice or (ii) the Takeda License. The Company shall not make or enter into any amendment, supplement or modification to, or grant any waiver under any provision of, the Takeda License without the Investors’ prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed) to the extent that such amendment, supplement, modification or grant would reasonably be expected to have a material adverse effect

37

on the timing, amount or duration of the Royalty Payments. Promptly, and in any event within 10 Business Days following the Company’s notice to a counterparty to any In-License of an alleged breach by such counterparty under any such In-License, the Company shall provide the Investors a copy thereof.

(a) The Company shall, and shall cause each of its Subsidiaries to, pay when due all material Taxes of any nature whatsoever now or hereafter imposed or assessed against the Company or such Subsidiary or their assets or upon the Company’s (or such Subsidiary’s) ownership, possession, use, operation or disposition thereof or upon the Company’s (or such Subsidiary’s) rents, receipts or earnings arising therefrom. The Company shall, and shall cause

38

each of its Subsidiaries to, accurately file on or before the due date therefor (taking into account proper extensions) all federal and state income Tax returns and other material Tax returns required to be filed. Notwithstanding the foregoing, the Company and its Subsidiaries may contest, in good faith and by appropriate proceedings diligently conducted, Taxes for which the Company and its Subsidiaries maintain adequate reserves in accordance with GAAP.

(b) The Company and the Investors agree that, for Tax purposes, (i) the Company and the Investors shall treat the transactions contemplated by this Agreement as indebtedness and shall treat each of the Investment Amounts as comprising separate debt instruments subject to the rules applicable to contingent payment debt instruments under Treasury Regulation Section 1.1275-4(b), and (ii) subject to the application of the Cap Amount or as otherwise required by applicable law, if multiple Investment Amounts have been paid by the Investors to the Company, then Royalty Payments shall for tax purposes be treated as paid pro rata in respect of each such Investment Amount. The parties hereto agree not to take any position that is inconsistent with the provisions of this Section 5.10 on any tax return or in any audit or other tax-related administrative or judicial proceeding unless (x) the other parties hereto have consented in writing (such consent not to be unreasonably withheld, conditioned or delayed) to such actions or (y) a party hereto receives advice in the form of a written memorandum or opinion from a nationally recognized accounting or law firm (at a more likely than not standard) that debt treatment is not appropriate, provided, that if any such party receives such advice, it shall promptly inform the other parties hereto thereof, and if another party hereto receives written advice from a nationally recognized accounting or law firm (at a more likely than not standard) that debt treatment is appropriate, the parties hereto shall in good faith discuss the differing conclusions and attempt to reconcile the differences, and if they are unable to do so, each such party may take its own position in respect thereof. If there is an inquiry by any Governmental Entity of the Investors or the Company related to the treatment described in this Section 5.10, the parties hereto shall cooperate with each other in responding to such inquiry in a reasonable manner which is consistent with this Section 5.10.

(c) Notwithstanding anything to the contrary in this Agreement (but subject to the requirement in Section 5.10(b) to treat the transactions contemplated hereby as indebtedness and subject to the Company’s obligation to pay additional amounts pursuant to Section 5.10(d)), each of the Investors and the Company shall be entitled to withhold and deduct (or cause to be withheld and deducted) from any amount payable under this Agreement to any other party any Tax that any Investor or the Company, as applicable, determines that it is required to withhold and deduct under applicable law, and any such amount withheld and deducted shall be treated for all purposes of this Agreement as being paid to such other party; provided, that each of the Investors and the Company shall give such other party reasonable prior notice and the opportunity, in good faith, to contest and prevent such withholding and deduction. The parties hereto shall use commercially reasonable efforts to give or cause to be given to the other parties hereto such assistance and such information concerning the reasons for withholding or deduction (including, in reasonable detail, the method of calculation for the deduction or withholding thereof) as may be reasonably necessary to enable an Investor or the Company, as applicable, to claim exemption therefrom, or credit therefor, or relief (whether at source or by reclaim) therefrom, and, in each case, shall furnish the Investors or the Company, as applicable, with proper evidence of the taxes withheld and deducted and remitted to the relevant taxing authority. Each Investor, severally but not jointly, agrees (i) to notify the Company in writing if (A) such Investor becomes ineligible to use or deliver the Applicable Withholding Certificate delivered by such Investor to the Company under Section

39

3.1(f) or (B) the Applicable Withholding Certificate delivered by such Investor to the Company under Section 3.1(f) ceases to be accurate or complete and (ii) to provide (to the extent it is legally eligible to do so) any additional Tax forms that the Company may reasonably request.

(i) if any applicable non-U.S. law requires the deduction or withholding of any additional amount from any payment hereunder to any Investor (which additional amount would not have resulted, solely as a result of the Company being organized, formed or tax resident in a jurisdiction outside of the United States), then the sum payable by the Company shall be increased as necessary so that, after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 5.10(d)), such Investor receives the full contractual amount of the applicable payment as if no such additional deduction or withholding had been required or made;

(ii) if any Investor is required to pay any additional Taxes with respect to payments hereunder under any applicable non-U.S. law the amount of which it would not otherwise have to pay solely as a result of the Company being organized, formed or tax resident in a jurisdiction outside of the United States, then the Company shall indemnify such Investor, within 10 days after demand therefor, for the full amount of such additional Taxes (including Taxes imposed or asserted on or attributable to amounts payable under this Section 5.10(d) under such non-U.S. law) payable or paid by such Investor; and

(iii) the amount treated as paid by the Company and received by the applicable Investor for purposes of this Agreement shall include all additional amounts and indemnity payments paid to such Investor pursuant to this Section 5.10(d) (and for the avoidance of doubt shall be fully creditable towards the Cap Amount) and shall be reduced by all indemnified Taxes withheld from payments to such Investor or payable directly by such Investor (and for the avoidance of doubt shall be fully deducted from the Cap Amount).

(e) Notwithstanding anything to the contrary in this Agreement, each party’s obligations under this Section 5.10 shall survive any assignment of rights by, or the replacement of, an Investor and the repayment, satisfaction or discharge of the Investment Amounts and any other obligations under this Agreement.

Following the Effective Date, no Investor may assign its obligations to pay its portion of the Investment Amount pursuant to this Agreement to any Person without the Company’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed, unless such assignment is to an Affiliate of an Investor and such Affiliate executes a joinder to this Agreement, in form and substance reasonably acceptable to the Company, and agrees to be an “Investor” for all purposes hereunder. Except as set forth in the prior sentence, an Investor may assign all or any of its rights and/or obligations under the Transaction Documents to any Person without the prior written consent of the Company; provided, however, that (x) if such Person is not an Investor, such assignment will be subject to such Person’s execution of a joinder to this Agreement, in form and substance reasonably acceptable to the Company, and agreement to be an “Investor” for all purposes hereunder, and (y) such Person shall not be a Prohibited Assignee. This Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective permitted successors and assigns. Any purported assignment in violation of this Section 9.4 shall be null and void.

The Company shall maintain a register for the recordation of the names and addresses of the Investors, the amount of each portion of the Investment Amount, and the amount of the Royalty Payments paid to each Investor, in the aggregate with respect to all Investment Amounts and individually with respect to each clause of the definition of Investment Amount, in a manner calculated consistent with Section 5.10(b) (the “Register”). The Company shall promptly record any assignment by an Investor permitted by this Agreement in the Register. The entries in the Register shall be conclusive absent manifest error, and the Company and the Investors shall treat

(b) No failure or delay on the part of any party hereto in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. No course of dealing between the parties hereto shall be effective to amend, modify, supplement or waive any provision of this Agreement.

Section 9.6 Entire Agreement. This Agreement, the Exhibits annexed hereto, the Schedules attached hereto and the Subordination Agreement constitute the entire understanding between the parties hereto with respect to the subject matter hereof and supersede all other understandings and negotiations with respect thereto, including any confidentiality agreement to which the Company (or any Affiliate of the Company), on the one hand, and any Initial Investor (other than Hercules Capital Inc. or any Affiliate thereof), on the other hand, is party or bound, and any such confidentiality agreement is hereby terminated without further force and effect, including any provisions that by the terms thereof would have otherwise survived the termination of such confidentiality agreement.

Section 9.8 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without giving effect to any choice or conflict of law provision or rule that would cause the application of the laws of any other jurisdiction.

EACH OF THE PARTIES REPRESENTS THAT THIS WAIVER IS KNOWINGLY, WILLINGLY, AND VOLUNTARILY GIVEN.

Section 9.10 Severability. If any term or provision of this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any situation in any jurisdiction, then, to the extent that the economic and legal substance of the transactions contemplated hereby is not affected in a manner that is materially adverse to any party hereto, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect and the enforceability and validity of the offending term or provision shall not be affected in any other situation or jurisdiction.

Section 9.11 Specific Performance. Each of the parties acknowledges and agrees that the other parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly, each of the parties agrees that, without posting bond or other undertaking, the other parties will be entitled to seek an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to seek to enforce specifically this Agreement and the terms and provisions hereof in any action, suit or other proceeding instituted in any court of the United States or any state thereof having jurisdiction over the parties and the matter in addition to any other remedy to which it may be entitled, at law or in equity.

51

Section 9.12 Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. The words “execution”, “signed” and “signature” and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement (to the extent permissible under governing documents) shall include images of manually executed signatures transmitted by facsimile or other electronic format (including “pdf”, “tif” or “jpg”) and other electronic signatures (including DocuSign and AdobeSign). The use of electronic signatures and electronic records (including any contract or other record created, generated, sent, communicated, received or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code. The foregoing shall apply to each other Transaction Document mutatis mutandis.

Section 9.13 Subordination Agreement. Notwithstanding anything to the contrary herein, the security interest granted to the Investors and their successors and assigns pursuant to this Agreement and the exercise of any right or remedy by the Investors and their respective successors and assigns hereunder are subject to the provisions of the Subordination Agreement.

Section 9.14 Relationship of the Parties. The relationship between the Investors and the Company is solely that of a borrower and lender, and neither the Investors nor the Company has any fiduciary or other special relationship with the other party or any of its affiliates. This Agreement is not a partnership or similar agreement, and nothing contained herein shall be deemed to constitute the Investors and the Company as a partnership, an association, a joint venture or any other kind of entity or legal form for any purposes, including any Tax purposes. The Investors and the Company agree that they shall not take any inconsistent position with respect to such treatment in a filing with any Governmental Entity.

Section 9.15 Remedies. The rights and remedies of the parties under this Agreement are cumulative and not alternative. Neither the failure nor any delay by any party in exercising any right, power or privilege under this Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. Unless specifically and expressly stated in this Agreement as exclusive, each remedy of the parties specified in this Agreement is not exclusive, and, subject to the terms of this Agreement, the parties shall be entitled to pursue any available legal or equitable remedy for breach of this Agreement or any provision hereof.
