On a Licensed Product-by-Licensed Product and country-by-country basis, Horizon shall have the right to deduct from the royalty payment that would otherwise have been due under Section 6.6(a) with respect to Net Sales of such Licensed Product in such country an amount equal to [***] of any [***] paid by Horizon or its Affiliate or Sublicensee to any Third Party (including any [***] under an Alpine Third party Agreement reimbursed by Horizon to Alpine) in consideration for a license or other rights under any Information or Patents owned or controlled by a Third Party that is [***] to Develop,

Manufacture, or Commercialize such Licensed Product in such country (including under an Alpine Third Party Agreement pursuant to Section 2.7(b)).

(f) Royalty Floor. In no event shall the application of Section 6.6(c), Section 6.6(d) and Section 6.6(e) reduce the royalty payable on Net Sales of a Licensed Product in a country in a Calendar Quarter during the Royalty Term to less than [***] of the royalty that would be payable on Net Sales of such Licensed Product in such country determined in accordance with Section 6.6(a) (as reduced by Section 6.6(c), as applicable) without application of any such reductions; provided however that any amounts paid to Third Parties as described in Section 6.6(e) that could not be applied due to application of the royalty floor set forth in this Section 6.6(f) may be carried forward and applied against payments of royalties under Section 6.6(a) owing in respect of such Licensed Product and such country on a Calendar Quarter basis, subject however to the application of the royalty floor in each subsequent Calendar Quarter.

(g) Royalty Reports and Payments. Within [***] following the end of each Calendar Quarter, commencing with the Calendar Quarter in which the First Commercial Sale of any Licensed Product is made anywhere in the Territory, Horizon shall provide Alpine with a report containing the following information for the applicable Calendar Quarter: (i) [***], (ii) [***] (iii) [***] (iv) [***]. Concurrent with the delivery of the applicable quarterly report, Horizon shall pay in Dollars all amounts due to Alpine pursuant to Section 6.6 in such Calendar Quarter.

6.7 Payments Under Third Party License Agreements. As between the Parties, Alpine shall be solely responsible for any royalties and other payments to Third Parties under any license or other agreement existing as of the Effective Date or entered into during the Term (subject to Section 2.7(b) with regard to any Alpine Third Party Agreement) by Alpine or its Affiliate pursuant to which Alpine gains Control of any Licensed Technology.

6.8 Currency of Payments. Unless otherwise set forth in this Agreement or agreed to by the Parties, all payments under this Agreement shall be made in Dollars by wire transfer of immediately available funds into an account designated by Alpine. Net Sales outside of the U.S. shall be first determined in the currency in which they are earned and shall then be converted into an amount in Dollars using Horizon’s customary and usual conversion procedures used in preparing its financial statements pursuant to GAAP for the applicable reporting period.

6.9 Late Payments. If Alpine does not receive payment of any undisputed sum due to it on or before the due date, Alpine shall provide notice to Horizon of such late payment. If Horizon does not make any payment within [***] following receipt of such notice, then any portions thereof due hereunder which are not paid on the date such payments are due under this Agreement will bear interest at the lesser of (a) [***] or (b) [***], in each case calculated on the number of days such payment is delinquent, [***].

6.10 Records; Audits. Horizon and its Affiliates will, and Horizon will cause each of its Sublicensees, if any, to, maintain complete and accurate records in sufficient detail to confirm the accuracy of the calculation of royalty payments and the achievement of milestone events, for a period of [***] after the Calendar Year in which such sales or events occurred. Upon reasonable prior notice, such records of Horizon and its Affiliates shall be made available during regular business hours for a period of [***] from the end of the Calendar Year to which they pertain for examination, and not more often than once each Calendar Year (unless there is a just cause for an additional examination based upon results of the earlier audit during such Calendar Year), by an independent certified public accountant selected by Alpine and reasonably

acceptable to Horizon, for the sole purpose of and only to the extent necessary for verifying the accuracy of the financial reports furnished by Horizon pursuant to this Article 6. Such independent accountant shall disclose to Alpine only the amounts that such independent accountant believes to be due and payable hereunder to Alpine, details concerning any discrepancy from the amount paid and the amount due, and shall disclose no other information revealed in such audit. The records for any particular Calendar Year shall only be subject to [***] audit hereunder. Any and all records examined by such independent accountant shall be deemed Horizon’s Confidential Information which may not be disclosed by such independent accountant to any Third Party, and Horizon may require such independent accountant to enter into an appropriate written agreement obligating it to be bound by obligations of confidentiality and restrictions on use of such Confidential Information that are no less protective than those set forth in Article 10. If, as a result of any inspection of the books and records of Horizon, it is shown that payments under this Agreement were less than the amount which should have been paid, then Horizon shall make all payments required to be made from the original due date to eliminate any discrepancy revealed by such inspection within [***] of such finding. If, as a result of any inspection of the books and records of Horizon, it is shown that payments under this Agreement were more than the amount which should have been paid, then Alpine shall, at Horizon’s election, either make all payments required to be made to eliminate any discrepancy revealed by such inspection within [***] of such finding or credit such amounts to Horizon against future payments. Alpine shall pay for such audits, except that in the event that the audited amounts were underpaid by Horizon by more than [***] of the undisputed amounts that should have been paid during the period in question as per the audit, Horizon shall pay the costs of the audit.

6.11 Taxes.

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the efforts of the Parties under this Agreement.

(b) VAT on Payments. All payments due under this Agreement are exclusive of VAT. If any VAT is chargeable in respect of amounts payable pursuant to this Agreement, VAT shall be charged at the applicable rate required by applicable Law and the party making such payment shall pay the VAT amount on receipt of a VAT invoice in the appropriate form.

(c) Withholding Tax; Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Horizon to Alpine under this Agreement. To the extent Horizon is required under the Code, or any other tax Laws to deduct and withhold taxes on any payment to Alpine, Horizon shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Alpine an official tax certificate or other reasonable evidence of such withholding. If any taxes are so deducted or withheld, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to Alpine. Upon Horizon’s reasonable request, Alpine shall provide Horizon any tax forms (including a United States tax “residency certificate”, Internal Revenue Service Form W-8BEN or W-8ECI or other applicable Internal Revenue Service Form) that may be reasonably necessary in order for Horizon to determine whether to withhold tax on any such payments or to withhold tax on such payments at a reduced rate under the Code or any other tax Laws, including any applicable bilateral income tax treaty. Horizon shall give reasonable support so that any withholding tax or value added tax may be minimized or avoided to the extent permitted under the applicable Laws and treaties. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by applicable Laws, of

withholding taxes, value added taxes, 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 value added tax. Horizon shall require its Sublicensees in the Territory to cooperate with Alpine in a manner consistent with this Section 6.11(c). Notwithstanding the foregoing, (i) if Horizon assigns or transfers this Agreement or its rights and obligations thereunder or changes its jurisdiction of tax residency, and such transfer, assignment or change increases the amount of taxes required to be deducted or withheld from or paid with respect to the payments to Alpine contemplated by this Agreement, Horizon and its assignee or transferee shall pay Alpine an additional amount such that Alpine shall receive, on an after-tax basis, the same amount it would have received had no such transfer or assignment been made; or (ii) if Alpine assigns or transfers this Agreement or its rights and obligations thereunder or changes its jurisdiction of tax residency, and such transfer, assignment or change increases the amount of taxes required to be deducted or withheld from or paid with respect to the payments to Alpine contemplated by this Agreement, then any amount payable to Alpine or its assignee or transferee under this Agreement shall be limited to the amount that would have been payable to Alpine had no such assignment, transfer or change occurred. On or prior to the Effective Date, Alpine shall deliver to Horizon a valid exemption certificate issued by the German Federal Tax Office.

Each Party shall share with the other Party all Information available to it regarding such alleged Product Infringement.

(ii) Enforcement Rights.

(1) Horizon Controlled Patents.

a. Horizon’s First Right to Enforce. As between the Parties, Horizon shall have the first right, but not the obligation, to bring a suit or other action against any Person engaged in a Product Infringement of, or any other action or proceeding regarding alleged or threatened infringement or claim of invalidity or unenforceability of, any Horizon Controlled Patent to defend against any challenge to any of the foregoing, at Horizon’s cost and expense. Horizon shall keep Alpine regularly informed of the status and progress of such enforcement or defense efforts, shall reasonably consider Alpine’s comments on any such efforts, including determination of litigation strategy and filing of material papers to the competent court. Alpine shall provide Horizon reasonable assistance in such enforcement or defense pursuant to this Section 7.3(a)(ii)(1)a, at Horizon’s request and expense, including joining such action as a party plaintiff if required by applicable Laws to pursue such action. In addition, [***] Alpine shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense.

b. Alpine’s Step-In Right to Enforce. If (A) Horizon elects not to commence a suit to enforce any Horizon Controlled Patent that Horizon has the first right to enforce against any Person pursuant to Section 7.3(a)(ii)(1)a, or settle or otherwise secure the abatement of such infringement or not to defend against any challenge to any of the Horizon Controlled Patent, or (B) Horizon fails to commence such suit within [***] (or such shorter period necessary to initiate and maintain such action) of a request by Alpine to do so, then, [***] Alpine shall have the right, but not the obligation, to commence a suit or take action to enforce such Horizon Controlled Patent against such infringement in the Territory or to defend against such challenge, at Alpine’s cost and expense. In such event and to the extent time permits, promptly after Horizon’s notice to Alpine that it does not elect to enforce such Horizon Controlled Patent or to defend against such challenge, the Parties shall meet to discuss in good faith the strategy for enforcing such Horizon Controlled Patent or defending against such challenge. Alpine shall keep Horizon regularly informed of the status and progress of such enforcement or defense efforts, shall reasonably consider Horizon’s comments on any such efforts, including determination of litigation strategy and filing of material papers to the competent court.

(f) Settlement. The enforcing Party shall not enter into any settlement or compromise of any suit, action or proceeding pursuant to Section 7.3 (other than pursuant to Section 7.3(g)), (i) in a manner that would diminish the rights or interests of the non-enforcing Party or admit the invalidity or unenforceability of any Patent Controlled by the non-enforcing Party without the prior written consent of the non-enforcing Party, such consent not to be unreasonably withheld; or (ii) that would impose any cost or liability on the non-enforcing Party, without the non-enforcing’s Party’s prior written consent, at the non-enforcing Party’s sole discretion.

(g) Other Infringement of Patents. For any and all infringement of any Sole Program Patent other than as provided elsewhere in this Section 7.3, (i) Alpine shall have the sole right, but not the obligation, to bring an appropriate suit or other action against any person or entity engaged in such other infringement of any such Sole Program Patent owned by Alpine that is not a Horizon Controlled Patent or Alpine Controlled Patent, in its sole discretion, and shall bear all related expenses and retain all related recoveries and (ii) Horizon shall have the sole right, but not the obligation, to bring an appropriate suit or other action against any person or entity engaged in infringement of any Sole Program Patent owned by Horizon or any other Patents owned or Controlled by Horizon that relate to any Licensed Compound or Licensed Product, in its sole discretion, and shall bear all related expenses and retain all related recoveries,

9.2 Indemnification by Horizon. Horizon shall defend, indemnify, and hold Alpine and its Affiliates and their respective officers, directors, employees, and agents (the “Alpine Indemnitees”) harmless from and against any and all Claims to the extent that such Claims arise out of, are based on, or result from (a) the Development, Manufacture or Commercialization of Licensed Compounds or Licensed Products by or on behalf of Horizon or its Affiliates or Sublicensees, (b) the breach of any of Horizon’s obligations under this Agreement, including Horizon’s representations, warranties, and covenants set forth herein, or (c) the willful misconduct or negligence of Horizon or its Affiliates in performing under this Agreement. The foregoing indemnity obligation shall not apply to the extent that (i) the Alpine Indemnitees fail to comply with the indemnification procedures set forth in Section 9.3 and Horizon’s defense of the relevant Claims is actually prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any act or omission for which Alpine is obligated to indemnify the Horizon Indemnitees under Section 9.1.

9.3 Indemnification Procedures. The Party claiming indemnity under this Article 9 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of such Claim. The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought and, if the Indemnifying Party has failed to assume defense of such Claim within the time period required by Law to respond to any such Claim and the Indemnified Party has thereafter assumed and is conducting the defense of the Claim, the Indemnifying Party shall provide the Indemnified Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the

defense of the Claim for which the indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, conditioned or delayed. For clarity, the Indemnified Party may freely withhold its consent to a settlement of a claim with respect to Claims if (a) such settlement does not include a complete release from liability of the Indemnified Party or if such settlement would involve undertaking an obligation (including the payment of money by an Indemnified Party), (b) would bind or impair the Indemnified Party or (c) includes any admission of wrongdoing or that any intellectual property or proprietary right of the Indemnified Party or this Agreement is invalid, narrowed in scope or unenforceable. So long as the Indemnifying Party is actively defending the Claim in good faith, the Indemnified Party shall not settle or compromise any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (i) the Indemnified Party may defend against, consent to the entry of any judgment, or enter into any settlement with respect to such Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (ii) the Indemnifying Party shall remain responsible to indemnify the Indemnified Party as provided in this Article 9.

9.4 Limitation of Liability. EXCEPT WITH RESPECT TO ANY DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 10 OR ITS OBLIGATIONS IN SECTION 2.8, AND WITHOUT LIMITING OR RESTRICTING THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 9.1 OR 9.2, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

9.5 Insurance. Each Party shall procure and maintain insurance adequate to cover its obligations hereunder during the Term and consistent with normal business practices of companies similarly situated. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 9. Each Party shall provide the other Party with written evidence of such insurance upon request.

ARTICLE 10
CONFIDENTIALITY

10.1 Confidentiality. Each Party agrees that, during the Term and for a period of [***] thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder) any Confidential Information furnished to it by the other Party pursuant to this Agreement, except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties. Each Party will use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but no less than reasonable care) to ensure that its employees, agents, consultants, contractors, Sublicensees and other representatives do not disclose or make any unauthorized use of the Confidential Information of the other Party. Each Party will promptly notify the other upon discovery of any unauthorized use or disclosure of the Confidential Information of the other Party. The foregoing confidentiality and non-use obligations shall not apply to any portion of the

other Party’s Confidential Information that the receiving Party can demonstrate by competent written proof:

(a) was already known to the receiving Party or any of its Affiliates, other than by previous confidential disclosure by or on behalf of the disclosing Party or any of its Affiliates, at the time of disclosure by the other Party (provided that this exception shall not apply to Alpine with respect to any Research Program IP);

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

(c) becomes generally available to the public or otherwise part of the public domain after its disclosure as contemplated by this Agreement and other than through any act or omission of the receiving Party in breach of this Agreement;

(d) was disclosed to the receiving Party or any of its Affiliates on a non-confidential basis by a Third Party who, to the actual or constructive knowledge of the receiving Party, had no obligation of confidentiality to the other Party; or

(e) was independently discovered or developed by the employees, subcontractors, consultants or agents of the receiving Party or any of its Affiliates without use of or reference to the other Party’s Confidential Information, as evidenced by a contemporaneous writing.

10.2 Authorized Disclosure. Notwithstanding the obligations set forth in Section 10.1, a Party may disclose the other Party’s Confidential Information and the terms of this Agreement to the extent:

(a) such disclosure is reasonably necessary (i) to comply with the requirements of Regulatory Authorities with respect to obtaining and maintaining Regulatory Approval of a Licensed Product; or (ii) for prosecuting or defending litigation as contemplated by this Agreement;

(b) such disclosure is reasonably necessary to its employees, agents, consultants, contractors, licensees or Sublicensees on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement; provided that in each case, the disclosees are bound by written obligations of confidentiality and non-use at least as restrictive as those contained in this Agreement;

(c) such disclosure is reasonably necessary to any bona fide potential or actual investor, acquirer, merger partner, licensee, sublicensee, or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship; provided that, in connection with such disclosure, such Party shall inform each disclosee of the confidential nature of such Confidential Information, and the disclosees are bound by written obligations of confidentiality and non-use consistent with those contained in this Agreement; or

(d) such disclosure is reasonably necessary to comply with applicable Laws, including regulations promulgated by applicable security exchanges, court order, administrative subpoena or order or otherwise necessary for submitting information to the Internal Revenue Service or other Governmental Authority.

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 10.2(a) or 10.2(d), such Party shall promptly notify the other Party of such required disclosure and shall use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure. Any information disclosed pursuant to Section 10.2(a) through Section 10.2(d) shall still be deemed Confidential Information and subject to the restrictions set forth in this Agreement, including the foregoing provisions of Article 10.

10.3 Technical Publication. During the Term, [***]. A Party seeking to publish a publication containing Confidential Information of the other Party (including any joint Confidential Information) shall provide the other Party the opportunity to review and comment on such proposed publication (or where a copy of such publication or presentation is not available at such time, a draft or outline of such publication or description of such presentation) that relates to any Licensed Compound or Licensed Product at least [***] prior to its intended submission for publication. The other Party shall provide the Party seeking publication with its comments in writing, if any, as promptly as practicable after receipt of such proposed publication. The Party seeking publication shall consider in good faith any comments thereto provided by the other Party and shall comply with the other Party’s request to remove any and all of such other Party’s Confidential Information from the proposed publication. In addition, the Party seeking publication shall delay the submission for a period up to [***] in the event that the other Party can demonstrate reasonable need for such delay, including the preparation and filing of a patent application (or, in the case that a Party has a compelling business justification, for a longer period reasonably selected by that Party). Each Party agrees to acknowledge the contributions of the other Party and its employees in all publications as scientifically appropriate.

10.4 Publicity; Terms of Agreement.

(a) The Parties agree that the terms of this Agreement are the Confidential Information of both Parties, subject to disclosure authorized in this Article 10 and the special authorized disclosure provisions set forth in this Section 10.4.

(b) Public announcement of the execution of this Agreement shall be made substantially in the form of the joint press release attached hereto as Exhibit K, on or promptly after the Effective Date.

(c) After release of such joint press release in Exhibit K, if either Party desires to make a public announcement concerning the terms of this Agreement, such Party shall, except as otherwise provided herein, give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval (not to be unreasonably withheld, conditioned, or delayed). A Party commenting on such a proposed press release by the other Party shall provide its comments, if any, within [***] after receiving the press release from the other Party. Notwithstanding the foregoing, a Party shall have the right to make a public announcement or press release of the achievement of significant events in Development (including achievement of each milestone event set forth in Sections 6.4(a) and 6.4(b) and Sections 6.5(a) and 6.5(b)) or Commercialization of any Licensed Product in the Territory, even if beyond what may be strictly required by applicable Law and the rules of recognized stock exchanges, to the extent consistent with such Party’s own disclosure practices, subject to prior notice of such public announcement or press release to the other Party. The principles to be observed in such disclosures shall be accuracy, compliance with applicable Law and regulatory guidance documents, reasonable sensitivity to potential negative reactions of applicable Regulatory Authorities and the need to keep investors and others informed regarding the requesting Party’s business, including as required by the rules of recognized stock exchanges.

Except as provided in this subsection (c) or permitted under Section 10.2, no press release shall include the other Party’s Confidential Information without the prior written consent of such other Party. In relation to the other Party’s review of such an announcement, such other Party may make specific, reasonable comments on such proposed press release within the prescribed time for commentary. Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that has already been publicly disclosed by such Party, or by the other Party, in accordance with this Section 10.4, provided such information remains accurate as of such time.

(d) The Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement and summaries of the terms hereof with the U.S. Securities and Exchange Commission or other Governmental Authority as reasonably required to comply with applicable Laws or the rules of a nationally-recognized securities exchange. Each Party shall be entitled to make such filings, provided that it requests confidential treatment of the commercial terms, sensitive technical terms and other terms of this Agreement that a Party reasonably deems sensitive or competitive to the extent such confidential treatment is reasonably available to such Party; provided that the foregoing obligation to request confidential treatment shall not apply with respect to any disclosure of this Agreement by either Party to the U.S. Internal Revenue Service or similar Governmental Authority outside the U.S. In the event of any such filing, each Party will provide the other Party with a copy of this Agreement and related filings marked to show provisions for which such Party intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s comments thereon to the extent consistent with the legal requirements and the rules of any nationally recognized securities exchange, with respect to the filing Party, governing disclosure of material agreements and material information to be publicly filed.

10.5 Equitable Relief. Each Party acknowledges that its breach of this Article 10 may cause irreparable harm to the other Party, which cannot be reasonably or adequately compensated in damages in an action at law. By reasons thereof, each Party agrees that the other Party shall be entitled to seek, in addition to any other remedies it may have under this Agreement or otherwise, to obtain preliminary and permanent injunctive and other equitable relief to prevent or curtail any actual or threatened breach of the obligations relating to Confidential Information set forth in this Article 10 by the other Party.

10.6 Attorney-Client Privilege. Neither Party is waiving, nor will be deemed to have waived or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges recognized under the applicable law of any jurisdiction as a result of disclosing information pursuant to this Agreement, or any of its Confidential Information (including Confidential Information related to pending or threatened litigation) to the receiving Party, regardless of whether the disclosing Party has asserted, or is or may be entitled to assert, such privileges and protections. The Parties may become joint defendants in proceedings to which the information covered by such protections and privileges relates and may determine that they share a common legal interest in disclosure between them that is subject to such privileges and protections, and in such event, may enter into a joint defense agreement setting forth, among other things, the foregoing principles, but are not obligated to do so.

ARTICLE 11

(v) Timing. The hearing shall commence within [***] after the selection of the arbitrators.

(vi) Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

(vii) Patent and Trademark and Other Disputes.

12.2 Entire Agreement; Amendment. This Agreement, including the Exhibits hereto, and the SPA set forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof, including the Confidentiality Agreement. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party.

12.3 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by a Force Majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting such Force Majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, “Force Majeure” means, with respect to a Party, conditions beyond the reasonable control of such Party, including an act of God, war, terrorist act, labor strike or lock-out, epidemic, fire, earthquake, storm, release of radioactive material into the environment, or like catastrophe. Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a Force Majeure affecting such Party.

Notwithstanding anything to the contrary contained in this Section 12.3, the Parties acknowledge and agree that a COVID-19 pandemic and business disruptions related thereto (collectively, the “COVID Event”) are currently occurring as of the Effective Date and may worsen, and the Parties further acknowledge and agree that, as of the Effective Date, neither the COVID Event, nor any recurrence thereof, shall constitute a Force Majeure.

12.5 No Strict Construction; Headings. This Agreement has been prepared jointly by the Parties and shall not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The headings of each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. Except where the context otherwise requires, wherever used, the singular shall include the plural and the plural the singular. The use of any gender shall be applicable to all genders. The word “or” is used in the inclusive sense (and/or) unless the context dictates otherwise because the subjects of the conjunction are mutually exclusive. The term “including” means “including without limitation,” without limiting the generality of any description preceding such term. The term “shall” means “will”. In addition, (a) the words “hereof,” “herein,” “hereby” and derivative or similar words refer to this Agreement (including any Exhibits); (b) provisions that require that a Party or the Parties hereunder “agree,” “consent” or “approve” or the like shall require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter

or otherwise; and (c) neither Party or its Affiliates shall be deemed to be acting “on behalf of” or “under authority of” the other Party.

12.6 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other Party, except that a Party may make such an assignment or transfer without the other Party’s consent (i) to an Affiliate (for so long as such entity remains an Affiliate), provided that such assigning Party shall remain responsible for such Affiliate’s conduct or (ii) to a Third Party acquiror or its Affiliate in connection with a Change of Control of such Party (such Third Party, an “Acquiror”). Any successor or assignee of rights or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights or obligations. Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 12.6 shall be null, void and of no legal effect.

12.7 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other reasonable and customary acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

12.8 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Alpine are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code. The Parties agree that Horizon, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code solely applicable to the Licensed Compounds, [***] Licensed Technology, and Alpine Libraries, including without limitation Horizon’s right to retain all licenses to Licensed Technology granted herein. Without limiting the generality of the foregoing, the Parties intend and agree that any sale of Alpine’s assets under Section 363 of the Bankruptcy Code shall be subject to Horizon’s rights under Section 365(n) with respect to such Licensed Technology, that Horizon cannot be compelled to accept a money satisfaction of its interests in Licensed Technology, and that any such sale therefore may not be made to a purchaser “free and clear” of Horizon’s license rights without the consent of Horizon. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Alpine under the Bankruptcy Code, Horizon shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property solely applicable to the Licensed Compounds, [***] Licensed Technology, and Alpine Libraries and all embodiments of such intellectual property, and the same, if not already in its possession, shall be promptly delivered to them (i) upon any such commencement of a bankruptcy proceeding upon its written request therefor, unless Alpine elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under (i) above, following the rejection of this Agreement by or on behalf of Alpine upon written request therefor by Horizon. (The Parties acknowledge and agree that “embodiments” of intellectual property within the meaning of Section 365(n) include without limitation laboratory notebooks, inventory, research studies, data, and regulatory approvals to the extent such items are solely applicable to the Licensed Compounds, [***], Licensed Technology and Alpine Libraries). Additionally, if (a) a case under the Bankruptcy Code is commenced by or against Alpine, (b) this Agreement is rejected as provided in the Bankruptcy Code, and (c) Horizon elects to retain its rights hereunder as provided in Section 365(n) of the Bankruptcy Code, Alpine (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) shall not interfere with Horizon’s rights under this Agreement to Licensed Technology (including such embodiments), including any right to obtain such Licensed Technology (or such embodiments) from another entity, to the extent provided in Section 365(n) of the Bankruptcy Code. All rights, powers and remedies of Horizon provided herein are in addition to and not in

substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Bankruptcy Code) in the event of the commencement of a case under the Bankruptcy Code with respect to Alpine. The Parties agree that they intend the following rights to extend to the maximum extent permitted by law, and to be enforceable under Section 365(n) of the Bankruptcy Code: (I) the right of access to any Licensed Technology (including all embodiments thereof) of Alpine, which is necessary for the development, manufacture, supply, commercialization, sale, import or export of Licensed Compounds or Licensed Products, in any case solely as provided under this Agreement; and (II) the right to contract directly with any Third Party to complete the same.

12.9 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

12.10 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver (signed by the Party providing such waiver) relating to a particular matter for a particular period of time.

12.11 Independent Contractors. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties. No Party shall report this Agreement (and the transactions hereunder) as an entity or partnership for any tax purpose unless required pursuant to a “final determination” in accordance with Section 1313 of the Code.

12.12 No Third Party Beneficiaries. This Agreement is neither expressly nor impliedly made for the benefit of any party other than the Parties and their successors and permitted assigns, except for the Horizon Indemnitees and Alpine Indemnitees expressly entitled to indemnification as provided in Article 9 and only in accordance with the terms of such Article 9.

12.13 Counterparts; Electronic Delivery. This Agreement may be executed in counterparts, by original or PDF signature, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Signatures to this Agreement transmitted by email in “portable document format” (“.pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of this Agreement shall have the same effect as physical delivery of the paper document bearing original signature.
