For the avoidance of doubt, any payments made hereunder shall be considered a Revenue Interest Payment for the purposes of calculating Investor Return Payment Satisfaction. Notwithstanding the foregoing, with respect to any Fiscal Year during the Term in which a Permitted Company is Commercializing the Product such that NovaQuest would receive a Revenue Interest Payment greater than Zero Dollars ($0) under Section 4.1(a), then this Section 4.1(b) shall not be applicable to such Revenue Interest Payment.

If, by no later than December 31, 2028, the sum of all Investor Return Payments paid to NovaQuest hereunder does not equal or exceed Sixty-Two Million, Five Hundred Thousand Dollars ($62,500,000), then Company shall become immediately and irrevocably obligated to pay NovaQuest True-Up Payment One and shall make such payment by no later than March 1, 2029. “True-Up Payment One” means an amount equal to the difference between: (A) Sixty-Two Million Five Hundred Thousand Dollars ($62,500,000) and (B) the sum of all Investor Return Payments paid to NovaQuest on or before December 31, 2028; provided that in no event may True-Up Payment One be a negative number.

Company may exercise such prepayment option by paying NovaQuest the then-current Prepayment Amount and providing NovaQuest with written notice designating such payment as a prepayment pursuant to this Section 4.1(d) (such payment, a “Prepayment”). Company and NovaQuest agree that any Prepayment shall be deemed to be due and payable to NovaQuest upon its receipt, as consideration for NovaQuest’s provision of funding hereunder.

(e)

Satisfaction of Investor Return Payment Obligations; Payment Cap. Notwithstanding anything to the contrary herein, Company’s obligation to make any Investor Return Payments to NovaQuest will terminate upon the earliest to occur of the following (such occurrence, “Investor Return Payment Satisfaction”): (i) such time as the sum of all Investor Return Payments paid to NovaQuest as of a particular date of determination equals the Payment Cap in effect for such date of determination; or (ii) such time as NovaQuest has received a Prepayment in accordance with Section 4.1(d).

NovaQuest’s Account. All payments under this Agreement to NovaQuest shall be made in Dollars by wire transfer in immediately available funds to such accounts as NovaQuest designates in writing from time to time.

4.3

Taxes; Withholding.

(a)

If any Governmental Authority requires Company to deduct or withhold any amount from, or NovaQuest to pay any present or future Tax, assessment, or other governmental charge on, any payment by Company to NovaQuest (a “Withholding Payment” ), then Company shall, in addition to paying NovaQuest the amount reduced by such Withholding Payment, simultaneously pay NovaQuest an additional amount such that NovaQuest receives the full contractual amount of the applicable payment as if no such Withholding Payment had occurred (such additional amount, the “Gross-Up Amount”).

(b)

Notwithstanding Section 4.3(a), if a Withholding Payment is required solely as a result of (i) a Voluntary Transfer by NovaQuest after the Effective Date of this Agreement or (ii) the failure to provide an IRS Form W-9 pursuant to Section 4.3(c), then Company shall not be obligated to pay NovaQuest the Gross-Up Amount with respect to such Withholding Payment.

NovaQuest and any permitted transferee or assignee hereunder shall deliver at the closing, and at any other times as reasonably requested by the Company or required by law to reduce the amount of withholding, a properly completed IRS Form W-9 certifying that NovaQuest (or such permitted transferee or assignee) is exempt from “backup” withholding tax.

(d)

If Company is required to make a Withholding Payment to a Governmental Authority, Company shall deliver to NovaQuest the original or a certified copy of a receipt issued by such Governmental Authority evidencing its payment of such Withholding Payment.

(e)

For Tax purposes, Company and NovaQuest shall treat the transaction contemplated by this Agreement as indebtedness subject to the rules applicable to contingent payment debt instruments under Treasury Regulation Section 1.1275-4(b). Company shall prepare and provide NovaQuest with the “project payment schedule” in accordance with the requirements of Treasury Regulation Section 1.1275-4(b) and Company will reasonably consider any feedback with respect to the “projected payment schedule” from NovaQuest. If there is an inquiry by any Governmental Authority of Company or NovaQuest related to this Section 4.3(e), the Parties shall cooperate with each other in responding to such inquiry in a commercially reasonable manner consistent with this Section 4.3(e).

4.4

Interest. If any payment required to be paid by Company to NovaQuest under this Agreement is not made when due, then such outstanding payment will accrue interest, beginning on the date when the payment was due, at an annual rate equal to [*] plus the Prime Rate, subject to any limitation under Applicable Law. Such rate will be compounded every [*], commencing on the date on which such payment was due. Payment of accrued interest will accompany payment of the outstanding payment. “Prime Rate” means the prime rate as reported in The Wall Street Journal, New York edition, on the date such payment is due.

(iii)

such actions would contravene, violate, cause a breach or default under or give rise to a right of early termination under or require any third party consent, authorization or approval by any Person (including any Governmental Authority) that is not an Affiliate of the Company (other than which have already been obtained or that Company reasonably determines would not be burdensome to obtain upon NovaQuest’s reasonable request to obtain), any Applicable Law or contract to which the Company or any of its assets are bound (other than any contract entered into for purposes of contravening or avoiding the Company’s obligations hereunder), including, for the avoidance of doubt, any intercreditor agreement; or

(iv)

would result in adverse tax consequences to the Company or any of its Affiliates.

(e)

For the avoidance of doubt, the security interest granted to NovaQuest pursuant to this Section 4.5 (and any perfection, priority or protection thereof) shall be subject to the terms of any [*] executed from time to time after the date hereof, and with respect to any conflict between this Agreement and any [*].

Company’s Indemnification Obligations. Company hereby agrees to indemnify, defend, hold harmless, and reimburse NovaQuest and its Affiliates and their respective managers, directors, officers, employees, agents, and its and their respective successors, heirs, and assigns (collectively, the “NovaQuest Indemnitees”) from and against any losses, costs, claims, damages, Liabilities, or expenses (including reasonable attorneys’ and professional fees and other expenses of litigation) (each, a “Loss” and collectively, “Losses”) actually sustained or incurred by NovaQuest Indemnitees arising out of claims, suits, actions, or demands, in each case brought by a Third Party, or settlements or judgments arising therefrom (including personal injury, products liability, and intellectual property infringement or misappropriation claims) (each a “Third-Party Claim”) as a result or arising out of:

(a)

a Responsible Party’s, or its or their respective agent’s or contractor’s actions or inactions in connection with the Development, promotion, marketing, handling, manufacture, Commercialization, packaging, labeling, storage, distribution, pricing, reimbursement, transport, use, sale, or other disposition of the Product;

(b)

any breach by Company of a representation or warranty of Company contained in this Agreement or in any other agreement between the Parties contemplated by this Agreement or the breach or default by a Responsible Party of any covenant, agreement, or obligation of Company contained in this Agreement or in any other agreement between the Parties contemplated by this Agreement;

(c)

a Responsible Party’s failure to comply with Applicable Law or GxP; or

(d)

[*] recklessness, or intentional wrongful acts or omissions related to this Agreement of a Responsible Party, or contractors or any of their respective directors, employees, or agents.

10.2

Procedures.

(a)

Notice. If one or more NovaQuest Indemnitees seek indemnification (each, an “Indemnified Party”) under Section 10.1, then NovaQuest shall give prompt written notice to Company of the assertion of any Third‑Party Claim in respect of which indemnity may be sought hereunder. Such notice shall include a description of the Third‑Party Claim, the nature and amount of the applicable Loss, to the extent known at such time, and NovaQuest’s decision with respect to whether Company will assume the defense of the Third‑Party Claim. The failure NovaQuest to notify Company on a timely basis or provide such information as set forth above will not relieve Company of any liability that it may have to an Indemnified Party unless Company demonstrates that Company’s defense of such action is materially prejudiced by NovaQuest’s failure to give such notice and then solely to the extent thereof. The Indemnified Party shall provide Company with complete and correct copies of reasonably relevant papers and official documents received from or on behalf of the Third Party asserting the Third-Party Claim in connection with any Third-Party Claims for which indemnity is sought hereunder and such other information with respect thereto as Company may reasonably request. The Parties shall keep each other reasonably informed of any facts or circumstances that may be of material relevance in connection with the Loss for which indemnification is sought.

(b)

Appointment of Counsel. If NovaQuest elects to have Company assume the defense of any Third‑Party Claim for which indemnification is sought hereunder, then Company will promptly appoint a lead counsel in the defense of such Third‑Party Claim any legal counsel selected by Company that is reasonably acceptable to the Indemnified Party.

(c)

Right to Participate in Defense. Without limiting Section 10.2(b), any Indemnified Party shall be entitled to participate in the defense of such Third‑Party Claim assumed by Company and to employ counsel of its choice for such purpose. However, such employment shall be at the Indemnified Party’s own expense unless: (i) the employment thereof has been specifically authorized by Company in writing; (ii) Company has failed to assume the defense, diligently defend the claim, and employ counsel in accordance with Section 10.2(b) (in which case the Indemnified Party may control the defense); or (iii) the interests of the Indemnified Party and Company with respect to such Third‑Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Laws, ethical rules, or equitable principles, in which case such employment shall be at the expense of Company.

(d)

Settlement. With respect to the defense of any Third‑Party Claim assumed by Company, Company will only have the right to consent to the entry of any judgment or enter into any settlement with respect to such Third‑Party Claim upon the prior written consent of the Indemnified Party (not to be unreasonably, withheld, conditioned or delayed).

(e)

Cooperation. With respect to the defense of any Third‑Party Claim for which indemnification is sought and for which NovaQuest elects the defense thereof to be assumed by Company, the Indemnified Party shall reasonably cooperate in the defense or prosecution thereof, and Company shall reimburse the Indemnified Party for all its reasonable out‑of‑pocket expenses in connection therewith. In the event NovaQuest elects not to have Company assume the defense of any Third‑Party Claim for which indemnification is sought, then Company shall cooperate with the Indemnified Party in the defense or prosecution thereof, including by furnishing such records, information, and testimony, providing such witnesses and attending such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the Indemnified Party to, and reasonable retention by Company of, records and information that are reasonably relevant to such Third‑Party Claim, and making Company employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

(f)

NovaQuest Indemnified Party’s Defense of Third‑Party Claims. If either: (i) Company fails to timely (and in any event within [*] assume and diligently conduct the defense of any Third‑Party Claim upon NovaQuest’s election pursuant to Section 10.2(a); or (ii) NovaQuest elects not to have Company assume the defense of a Third‑Party Claim, then the Indemnified Party may assume the defense of, and settle, such Third‑Party Claim with counsel of its own choice and on such terms as it deems appropriate, without any obligation to obtain the consent of Company, at Company’s expense.

(g)

Limitations. The Company’s obligations pursuant to this ARTICLE X shall not apply to the extent such Third-Party Claims result from gross negligence or willful misconduct by any of the Indemnified Parties.

ARTICLE XI

MISCELLANEOUS

11.1

Governing Law; Waiver of Jury Trial. This Agreement shall be governed by and construed, interpreted, and enforced in accordance with the laws of the State of New York, as applied to agreements executed and performed entirely in the State of New York, without giving effect to the principles of conflicts of law thereof. EACH PARTY IRREVOCABLY WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING IN CONNECTION WITH OR RELATING TO THIS AGREEMENT OR ANY AGREEMENT ENTERED INTO PURSUANT HERETO AND AGREES THAT ANY SUCH SUIT, ACTION, OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

11.2

Dispute Resolution.

(a)

Subject to Section 11.3, prior to the initiation of any Arbitration between the Parties, any dispute, controversy, or claim arising under, out of, or in connection with this Agreement, including any subsequent amendments (a “Dispute”) shall be first discussed in good faith between the Parties’ Senior Officers. Either Party shall have the right to refer a Dispute to the Parties’ Senior Officers for attempted resolution by sending a written notice to the other Party setting forth in reasonable detail the nature of the Dispute (the “Dispute Notice”). If either Party provides a Dispute Notice, then the Senior Officer (or his or her designee) from each Party shall, by phone or in-person, discuss the Dispute in good faith, commencing within [*] after the delivery of the Dispute Notice and continuing until at least [*] after the delivery of the Dispute Notice.

(b)

If the two Senior Officers (or their designees) have not reached a mutually acceptable resolution to the Dispute within [*] after the delivery of the Dispute Notice, then the Dispute shall be resolved by final, binding arbitration conducted in accordance with the then-current Commercial Rules (the “AAA Rules”) of the American Arbitration Association or any successor entity (the “AAA”) including the Procedures for Large, Complex Commercial Disputes (including, as appropriate, the Optional Rules for Emergency Measures of Protection), as amended from time to time, except as provided in this Section 11.2 (“Arbitration”).

(c)

Selection of Arbitrators. The Arbitration tribunal shall consist of three (3) arbitrators, who shall be selected as follows: (i) [*] shall be selected by Company; (ii) [*] shall be selected by NovaQuest; and (iii) [*] shall be selected by the [*] (each such arbitrator, an “Arbitrator”). Each of the Arbitrators shall have prior experience in connection with the biopharmaceutical industry, or shall be a retired judge. No Arbitrator shall be a current or former employee, shareholder, officer, or director of, or consultant, or advisor to, or other representative of, either Party. [*].

(d)

Venue and Language. The venue of the Arbitration shall be New York, New York, USA. The Arbitration shall be conducted in English, and all foreign language documents shall be submitted in the original language and shall be accompanied by a certified translation into English.

(e)

Time Periods. The Arbitration shall be conducted expeditiously and efficiently, and absent good cause shown as determined by the Arbitrators, the Arbitrators shall conduct any evidentiary hearing within [*] of confirmation of the panel of Arbitrators. Upon the written mutual agreement of both Parties, any time period specified in this Section 11.2 or the [*] shall be extended or accelerated according to the Parties’ written mutual agreement. The Arbitrators shall take into account both the desirability of making discovery efficient and cost-effective and the needs of the Parties for an understanding of any legitimate issue raised in the Arbitration. The Arbitrators shall, upon the request of one or both parties, permit the exchange of documents relevant to the claims and defenses raised in the Arbitration. Unless the Parties mutually agree, no depositions or other discovery devices shall be permitted, absent extraordinary circumstances as determined by the Arbitrators.

(f)

Consolidation of Disputes. In order to facilitate the comprehensive resolution of related disputes, and upon request of any Party to the Arbitration proceeding, the Arbitrators may consolidate the Arbitration proceeding with any other Arbitration proceeding relating to this Agreement. The Arbitrators shall not consolidate such Arbitrations unless they determine that: (i) there are issues of fact or law common to the proceedings so that a consolidated proceeding would be more efficient than separate proceedings; and (ii) no Party would be prejudiced as a result of such consolidation through undue delay or otherwise. The Arbitrators shall have jurisdiction to decide matters of arbitrability.

(g)

Costs. The costs of the Arbitration, including reasonable fees plus expenses to be paid to the Arbitrator(s) and the reasonable out-of-pocket costs (including the costs incurred for translation of the documents into English, reasonable attorneys’ and expert witness fees, and reasonable travel expenses) of the prevailing Party shall be borne by: (i) the losing Party, if the Arbitrator(s) rule in favor of one Party on all disputed issues in the Arbitration; and (ii) the Parties, as allocated in writing by the Arbitrator(s) in a manner with a reasonable relationship to the outcome of the Arbitration, if the Arbitrator(s) rule in favor of one Party with respect to some issues and in favor of the other Party with respect to other issues and, in either case ((i) or (ii)), paid within [*] from the final decision by the Arbitrator.

(h)

Decision to be Binding. The Arbitrators shall render a reasoned arbitral award. The award by the Arbitrators shall be final and binding on the Parties, non-reviewable and non-appealable, and judgment upon any arbitral award may be entered and enforced by any court or other judicial authority of competent jurisdiction. The Parties’ agreement to arbitrate, and any arbitral award, shall be enforced under the Federal Arbitration Act.

(i)

Confidentiality. All Disputes under this Agreement shall be kept confidential. All settlement negotiations, proceedings, and any award and any information obtained from the other Party in connection with the Arbitration shall be deemed Confidential Information subject to ARTICLE VI, provided that the Parties further agree that such Confidential Information may be disclosed to the extent necessary to enforce any award or enforce this Agreement to arbitrate; provided that either Party may disclose such settlement information if required by the U.S. Securities and Exchange Commission, and such disclosing Party shall use its reasonable efforts to secure confidential treatment of such Confidential Information prior to its disclosure (whether through protective orders or otherwise) or with respect to any filing required by a securities agency, the Parties agree to use reasonable efforts to provide the other with a copy of any filing required by a securities agency that will be made publicly available regarding the Agreement or its terms to review prior to filing and to consider any comments of the other Party in good faith, and to the extent either Party is required to file or disclose this Agreement with a securities agency, if the Agreement may become publicly available, such Party shall consider in good faith the other Party’s comments with respect to confidential treatment of the Agreement’s terms and shall redact the Agreement in a manner allowed by the securities agency to protect sensitive terms, and shall be permitted to file the Agreement, as so redacted, with the securities agency.

11.3

Equitable Relief. Each of the Parties hereto acknowledges that the other Party may have no adequate remedy at law if it fails to perform any of its obligations under ARTICLE VI of this Agreement. In such event, each of the Parties agrees that the other Party shall have the right, in addition to any other rights it may have (whether at law or in equity), to pursue equitable remedies such as injunction and specific performance for the breach or threatened breach of any provision of such ARTICLE VI from any court of competent jurisdiction.

11.4

Expenses. Except as expressly set forth herein, each Party shall be responsible for and bear all of its own costs and expenses (including any legal fees, any accountants’ fees, and any brokers’, finders’, or investment banking fees or any prior commitment in respect thereof) with regard to the negotiation and consummation of the transactions contemplated by this Agreement. Notwithstanding the foregoing, each Party represents and warrants to the other that the other Party will not be liable for any brokerage commission, finder’s fee, or other like payment in connection with the transactions contemplated hereby because of any action taken by, or agreement or understanding reached by, that Party. If, after the Effective Date, Company requests an amendment of this Agreement in connection with any restructuring, reorganization, or similar transaction to which Company or any Affiliate of Company is a party, [*].

11.5

Relationship of the Parties. Nothing in this Agreement is intended to be construed so as to suggest that either Party (except as expressly set forth herein) is obligated to provide, directly or indirectly, any advice, consultations, or other services to the other Party. Neither Party shall have any responsibility for the hiring, termination, or compensation of the other Party’s employees or for any employee benefits of such employee. No employee or representative of a Party shall have any authority to bind or obligate the other Party to this Agreement for any sum or in any manner whatsoever or to create or impose any contractual or other liability on the other Party without such Party’s approval. For all purposes and notwithstanding any other provision of this Agreement to the contrary, each Party’s legal relationship under this Agreement to the other Party shall be that of independent contractor. This Agreement is not a partnership agreement, and nothing in this Agreement shall be construed to establish a relationship of co-partners or joint venturers between the Parties for any purpose, including any Tax purpose.

11.6

Successors and Assigns. Neither this Agreement nor any rights or obligations hereunder may be assigned in whole or in part by either Party, by operation of law or otherwise, without the prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), provided that, notwithstanding the foregoing: (a) subject to the terms of any [*], NovaQuest may, upon delivery of reasonable written notice to Company, (i) assign, sell, or otherwise transfer this Agreement to an Affiliate of NovaQuest, and (ii) assign, sell, pledge, contribute, or otherwise transfer, in whole or in part, its rights to receive any payments under this Agreement, its rights to enforce such payment rights, and its rights to conduct or request audits or receive information and audit findings under ARTICLE V to any Person that is not a Company Competitor, and such Person may assign, sell, pledge, contribute, or otherwise transfer such rights to another Person that is not a Company Competitor; and (b) Company may assign, sell, pledge, contribute or otherwise transfer its rights or obligations hereunder in accordance with Section 8.2, Section 8.3, and Section 8.4. This Agreement shall be binding upon, and subject to the terms of this Section 11.6, inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns, provided that [*]. Any assignment or attempted assignment not in accordance with this Section 11.6 shall be null and void. Company shall maintain at one of its offices a register for the recordation of the names and addresses of the Parties and the commitments of, and principal amounts (and stated interest) under the Agreement owing to, each Party pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Parties shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Party hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Parties, at any reasonable time and from time to time upon reasonable prior notice. The Parties agree that the foregoing is intended to ensure that the Agreement is in “registered form” within the meaning of Treasury Regulation Section 5f.103-1(c) and shall be interpreted consistently therewith. For avoidance of doubt, Company may assign, assign, sell, pledge, contribute or otherwise transfer its rights or obligations under such portions of Astellas Revenue that are not part of the Revenue Interest Payments due and payable to NovaQuest.

11.7

Notices. All notices, consents, waivers, requests, and other communications hereunder shall be in writing and shall be delivered in person, sent by confirmed electronic mail, sent by overnight courier (e.g., Federal Express), confirmed facsimile transmission or posted by registered or certified mail, return receipt requested, with postage prepaid, to following addresses of the Parties:

11.8

Severability.

All other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties as nearly as may be possible. Such invalidity, illegality, or unenforceability shall not affect the validity, legality, or enforceability of such provision in any other jurisdiction. Nothing in this Agreement shall be interpreted so as to require a Party to violate any Applicable Law.

11.9

Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition.

11.10

Entire Agreement. This Agreement, [*], including any Exhibits or Schedules to any the foregoing, set forth all of the covenants, promises, agreements, warranties, representations, conditions, and understandings between the

Words of any gender include the other gender, and words using the singular or plural number also include the plural or singular number, respectively. Neither Party hereto shall be deemed to be the drafter of this Agreement for the purposes of construing this Agreement against one Party or the other. If any notice or other action or omission is required to be taken by a Party under this Agreement on a day that is not a Business Day, then such notice or other action or omission shall be deemed to require to be taken on the next occurring Business Day.
