any activities or participate in any business or otherwise compete with ARS anywhere in the Territory with respect to the Exploitation of any therapeutic containing the same active pharmaceutical ingredient, derivative or active metabolite as any
Product without the prior written consent of ARS. 
 3.5.2 Each of the Parties recognizes that the restrictions contained in, and the terms
of, this Section 3.5 are properly required for the adequate protection of the license set forth in Section 3.1 and ARS’s rights under this License Agreement, and agree that if any provision in this Section 3.5 is determined by
any court to be unenforceable by reason of its extending for too great a period of time or over too great a geographic area, or by reason of its being too extensive in any other respect, such covenant shall be interpreted to extend only for the
longest period of time and over the greatest geographic area, and to otherwise have the broadest application as shall be enforceable. 
 3.6
Technology Disclosure; Assistance. Within [***] after the Effective Date, AEGIS shall deliver, at [***], to ARS, or provide ARS with copies of, (a) the AEGIS Know- How Rights, consisting of (i) copies of any publications related to

3.7.3 In the event ARS does not (directly or with or through any of its Affiliates or sublicensees) use Commercially Reasonable Efforts to
Exploit a Product, then AEGIS will have the right to terminate the License with respect to such Product as provided in this Section 3.7.3, and such termination shall be the sole remedy for such failure. Said termination will occur upon AEGIS
delivering to ARS a written notice of termination, unless ARS responds within [***] after receipt of said notice with evidence which demonstrates that ARS (or any of its Affiliates or sublicensees) is using Commercially Reasonable Efforts to Exploit
a Product. 
 i) If there is a dispute between the Parties regarding whether ARS (or any of its Affiliates or sublicensees) is using
Commercially Reasonable Efforts to Exploit a Product, the dispute resolution procedures pursuant to Section 10.2 shall apply and no termination will occur unless and until it is finally determined pursuant to such procedures that ARS has not
(directly or with or through any of its Affiliates or sublicensees) used Commercially Reasonable Efforts to Exploit such Product. In the event that it is finally determined pursuant to such procedures that ARS has not (directly or with or through
any of its Affiliates or sublicensees) used Commercially Reasonable Efforts to Exploit such Product, then AEGIS shall not have the right to terminate the License for such Product if ARS puts in place and begins implementation of a commercially
reasonable plan, mutually agreed to by the Parties, for compliance with its obligation to use Commercially Reasonable Efforts to Exploit such Product within [***] after such final determination. 

ii) If AEGIS terminates the License granted with respect to a Product as permitted by Section 3.7.3, ARS shall assign and transfer
exclusively to AEGIS (even as to ARS) all data and intellectual property and any Joint Patent Rights owned by ARS that relate solely to such Product, [***]. AEGIS’ rights to terminate the License under this Section 3.7.3 shall not begin
until [***] after the Effective Date. 
 iii) In the event the License Agreement has been terminated and ARS has assigned and transferred
exclusively to AEGIS all data and intellectual property and any Joint Patent Rights owned by ARS that relate solely to such Product, including but not limited to all preclinical and clinical data, related protocols and all rights to any and all
patents and patent applications specific to the Product, then AEGIS shall agree to pay to ARS an amount equal to [***] of the net proceeds from any royalties or other amounts that AEGIS receives from third party licensees on net sales of the Product
up to [***] of the actual documented third party development costs incurred by ARS specific to the development of the Product.

 3.8 Research and Development Plans
and Reports. 
 3.8.1 During the term of this License Agreement and subject to third party confidentiality, AEGIS may
offer its recommendations to ARS for development as to any ways which may be more effective for utilizing the Excipient(s). For avoidance of doubt, neither party shall have any legally binding obligations or liabilities concerning the foregoing
recommendations.

on in accordance with applicable data protection legislation, such as the Health Insurance Portability and Accountability Act of 1996 as well as all other applicable laws and regulations.” 

3.9 Excipient Toxicity Studies. In the event that ARS conducts any toxicity studies solely related to the Excipient or the Material, in
whole or in part, (the “Material Tox Studies”), ARS agrees to provide to AEGIS a draft copy of the intended protocol(s) to be used for such Material Tox Studies; and ARS will give due considerations to any recommendations which
AEGIS may give for improving the protocol(s) for the Material Tox Studies. ARS agrees to provide any data arising from the Material Tox Studies (“Material Tox Data”) to AEGIS within [***] after ARS receives the
Material Tox Data. AEGIS may include in its Drug Master File(s) (“DMF”) for the Excipient such portions of or information from the Material Tox Data as is required or appropriate for inclusion in its DMF and may provide copies of
such Material Tox Data to its licensees, provided that prior to sharing with any third party, AEGIS and ARS shall redact all ARS Confidential Information including all references to ARS, the Product and/or the Compound; provided however that the
Material Tox Data added to the DMF shall not be redacted.

 4.4 Royalties. 

4.4.1 Within [***] following the First Commercial Sale of a Product in each country in the Territory, ARS shall give written notice to AEGIS
thereof. 
 4.4.2 As partial consideration for the grant to ARS of the rights under Section 3.1, during the applicable Royalty Term,
ARS shall pay to AEGIS royalties on Annual Net Sales of Products, on a country-by-country and
Product-by-Product basis in accordance with this Section 4.4, in an amount equal to the applicable rate set forth in the table in this Section 4.4.2, below,
times the Annual Net Sales of Products by ARS, its sublicensees and their respective Affiliates, subject to the applicable reductions as set forth in Sections 4.4.3 through 4.4.6; but in no event will the royalty rate be reduced pursuant to Sections
4.4.3 through 4.4.6 by more than [***] (although any such unused reduction sum will be carried forward and applied against future payments).

 4.4.3 The royalty percentage then applicable under this Section 4.4 to Net Sales of any Product made in
any country in the Territory shall be reduced by [***] from [***] to [***] if at the time of the sale of such Product in such country, the use, manufacture, offer for sale, sale and import of such Product in such county is not covered by a Valid
Claim. 
 4.4.4 The royalty percentage then applicable to Net Sales of any Product made in any country in the Territory shall be further
reduced by [***] from that in Section 4.4.3 from [***] to [***], if, at the time of the sale of such Product in such country, there are Competing Products that collectively account for [***] or more of all sales across all indications for which
the Products are marketed in that country. In the event that Competing Products in any country no longer collectively account for [***] or more of all sales across all indications for which the Products are marketed in that country, then such [***]
reduction shall be suspended. 
 The term “Competing Product” shall mean [***]. 

4.4.5 If the level of competition, patent protection or the general commercial environment for such Product in such country materially affect
the commercial viability of such Product in such country at the royalty rate then applicable under this Section 4.4, then AEGIS shall, upon written notice by ARS, negotiate and agree with ARS in good faith a reduction of such royalty rates, as
applicable to such Product in such country. 
 4.4.6 Third Party Licenses. 

(a) If ARS determines, in its reasonable judgment (subject to subpart b below), that the intellectual property rights of a third party are
necessary for the practice of any AEGIS Technology in accordance with this License Agreement, then the royalty and milestone amounts owed to AEGIS hereunder for Exploiting the AEGIS Technology in the country (or countries) where such third party
intellectual property rights are enforceable shall be subject to a credit reduction in an amount equal to [***] of the amount of any payments that ARS (or any of its sublicensees) pays such third party to use such third party intellectual property
rights; provided, no payment to AEGIS shall be reduced by more than [***] of the amount payable before any reductions or credits (although any unused excess credit may be carried forward and applied against future payments). 

(b) If AEGIS disputes ARS’s determination under Section 4.4.6(a) that the technology, and/or a license to intellectual property
rights, of such third party is necessary for the practice of any AEGIS Technology in accordance with this License Agreement, AEGIS may submit such dispute to an independent third party arbiter, mutually agreed to by the Parties, such agreement not
to be unreasonably withheld, delayed, or conditioned, and such arbiter to have at least [***] experience in the biopharmaceutical industry overseeing drug development or patent law, who shall determine within [***] whether, in the absence of rights
granted by such third party, the practice of any AEGIS Technology in accordance with this License Agreement would likely or actually infringe or misappropriate such third party’s intellectual property. Such arbiter’s determination shall be
final and binding on the Parties, and any dispute with respect to such arbiter’s determination shall not be submitted for resolution pursuant to Section 10.2. Additionally, any determination of likely or actual infringement shall be deemed
a determination that such license to intellectual property rights of a third party is “necessary” for purposes of Section 4.4.6(a). 

  
 9 












 4.4.7 ARS, its sublicensees or their respective Affiliates shall not intentionally sell any
Product to a third party at a discount in order to induce the same third party to purchase any other products or services. 
 4.5
Royalty Reports. 
 4.5.1 After the First Commercial Sale of the first Product, ARS shall keep complete and accurate
records in sufficient detail to properly reflect all gross sales and Net Sales, and to enable the royalties payable to AEGIS under Section 4.4 to be determined. 

4.5.2 Within [***] after the end of each Calendar Quarter during the term of this License Agreement following the First Commercial Sale of the
first Product by ARS, its sublicensees or their respective Affiliates, ARS shall furnish to AEGIS a written report showing in reasonably specific detail, on a
country-by-country and Product-by-Product basis, (a) the gross sales of Products
sold by ARS, its Affiliates and sublicensees during such Calendar Quarter and the calculation of Net Sales from such gross sales; (b) the calculation of the royalties which shall have accrued based upon such Net Sales; (c) the withholding
taxes, if any, required by law to be deducted with respect to such Net Sales; and (d) the exchange rates, if any, used in determining the amount of U.S. dollars. 

4.5.3 All royalties shown to have accrued by each royalty report provided under this Section 4.5 shall be payable on the date such
royalty report is due. Payment of royalties in whole or in part may be made in advance of such due date. 
 4.6 Audits. 

4.6.1 Upon the written request of AEGIS and not more than [***] in each Calendar Year, ARS shall permit an independent certified public
accounting firm of nationally recognized standing, selected by AEGIS and reasonably acceptable to ARS, [***], to have access during normal business hours to such of the records of ARS as may be reasonably necessary to verify the accuracy of the
royalty reports under Section 4.5 for any year ending not more than [***] prior to the date of such request. The accounting firm shall be required to sign a confidentiality agreement for the benefit of, and in a form reasonably acceptable to,
ARS, and shall disclose to AEGIS and ARS only whether the reports are correct or not and the specific details concerning any discrepancies. No other information shall be shared. 

4.6.2 If such accounting firm concludes that additional royalties were owed during the audited period, ARS shall pay such additional royalties
within [***] after the date AEGIS delivers to ARS such accounting firm’s written report so concluding. If such accounting firm concludes that ARS has overpaid royalties during the audited period, ARS shall have the right to credit the amount of
the overpayment against each subsequent quarterly payment due to AEGIS until the overpayment has been fully applied to pay such additional royalties. If the overpayment is not fully applied prior to the final quarterly payment of royalties due
hereunder, AEGIS shall [***] refund to ARS an amount equal to any remaining overpayment. The fees charged by such accounting firm shall be paid by AEGIS; provided, however, if the audit discloses that the royalties payable by ARS for
such period are more than [***] of the royalties actually paid for such period, then [***] shall pay the reasonable fees and expenses charged by such accounting firm. 

4.6.3 ARS shall include in each permitted sublicense granted by it pursuant to the License Agreement a provision requiring the sublicensee to
make reports to ARS, and to keep and maintain records of sales made pursuant to such sublicense, and to permit audits by ARS of such records. ARS shall grant access to such reports by AEGIS’ independent accountant as set forth in
Section 4.6.1. 

  
 10 












 4.6.4 AEGIS shall treat all financial information subject to review under this
Section 4.5 as Confidential Information of ARS consistent with Section 7, and shall cause its accounting firm to retain all such financial information in confidence. 

4.7 Payment Method. All payments owed under this License Agreement shall be paid in United States Dollars in immediately available
funds and shall be made by wire transfer from a United States bank located in the United States to such bank account as designated from time to time by AEGIS to ARS. For the purposes of computing Net Sales of Products commercialized by ARS that are
sold in a currency other than U.S. dollars, such currency shall be converted into U.S. dollars as calculated at the actual average rates of exchange for the pertinent month as reported in the Wall Street Journal, or at such other exchange ratio as
the Parties may mutually approve in writing. 
 4.8 Taxes and Duties. If ARS is required to withhold any
tax to the tax or revenue authorities in any country regarding any payment to AEGIS due to the applicable laws of such country, such amount shall be deducted from the payment to be made by ARS, and ARS shall promptly notify AEGIS of such
withholding. Within a reasonable amount of time after making such deduction, ARS shall furnish AEGIS with copies of any documentation evidencing such withholding and the related payment by ARS to the applicable tax authority. Each Party agrees to
cooperate with the other in claiming exemptions from such deductions or withholdings under any agreement or treaty from time to time in effect, and in obtaining papers from or filing papers with the applicable tax authority. [***]. 

 

	5.	 OWNERSHIP AND RIGHTS FOR DATA
AND TECHNOLOGY 


 5.1 AEGIS Technology. Subject to the rights and licenses
specified in this License Agreement, AEGIS shall solely own all right title and interest in the AEGIS Data, AEGIS Inventions, AEGIS Know-How Rights, and AEGIS Patent Rights. 

5.2 ARS Technology. Subject to the rights and licenses specified in this License Agreement, ARS shall solely own all right title and
interest in the ARS Data, ARS Inventions, ARS Know-How Rights, and ARS Patent Rights. 
 5.3
Inventorship. Inventorship of Inventions shall be determined in accordance with U.S. patent laws (Title 35, United States Code), and, except as expressly provided otherwise in Section 5.4, 5.5 or 5.6, the inventor of an invention
(whether Aegis, ARS, or Aegis and ARS jointly) shall be the owner of such Inventions and any patent rights and other intellectual property rights in and to such Inventions. AEGIS personnel have executed, or will be caused to execute, agreements
requiring such personnel to assign to AEGIS all Inventions made by such personnel, and ARS personnel have executed, or will be caused to execute, agreements requiring such personnel to assign to ARS all Inventions made by such personnel. 

5.4 Inventions Related to the Compound. 

5.4.1 Ownership. As between AEGIS and ARS, ARS is the owner of all right, title and interest in and to the Compound, which shall be
included in ARS Technology, and all existing patents and patent applications (“ARS Patents”) and: 
 (a) AEGIS shall not (and
shall not attempt or purport to) file or prosecute in any country any patent application which claims or uses or purports to claim or use solely the Compound or the Product, or any information or other materials directly or indirectly derived
therefrom, without the prior express written consent of ARS. 

  
 11 












 (b) If there is an Invention related solely to Compound made or conceived by employees,
consultants, agents and others conducting work on behalf of AEGIS or its Affiliate, whether alone or jointly with one or more employees, consultants, agents and others conducting work on behalf of ARS, AEGIS agrees to [***] disclose such invention
to ARS and supply ARS with a copy of the disclosure for ARS’S evaluation purposes. ARS shall have the sole right to determine what, if any, patent applications should be filed on such Invention. AEGIS hereby assigns to ARS all right, title and
interest in any such Inventions and shall execute, and require its and its Affiliates personnel and contractors to execute, any documents reasonably required to confirm ARS’s ownership of such Inventions, and any documents required to apply
for, maintain and enforce any patent rights in such Inventions. 
 (c) Any new Invention claiming Compounds and/or ARS Technology, and not
claiming Excipients or Products or Aegis Technology, that is invented in whole or in part by ARS, regardless of whether it may be commercially useful, shall be owned solely by ARS. Nothing herein shall affect the right of ARS to invent and seek
intellectual property protection for inventions that do not claim AEGIS Technology. ARS shall obtain Aegis’ prior written approval, which shall not be unreasonably withheld, conditioned or delayed, to the disclosure of the Excipient as a known
excipient, and to the disclosure and use of information from studies involving the Excipient or Product, in the specification of any ARS Patent (which pursuant to Section 5.5.1 shall not claim or purport to claim the Excipient, and pursuant 5.6
shall not claim or purport to claim a Joint Invention). 
 5.4.2 No Implied License. This License
Agreement shall not grant any license or other rights to AEGIS in any patent rights or other intellectual property rights of ARS, and no rights are provided to AEGIS under any patents, patent applications, trade secrets or other proprietary rights
of ARS. In particular, no rights are provided to use the Compound and any patents or intellectual property of any kind to AEGIS for profit-making, commercial or research purposes, including but not limited to sale of the Compound, use in
manufacturing, provision of a service to a third party in exchange for consideration, or use in research or consulting by a commercial or not for-profit entity. 

5.5 Inventions Related to the Excipient. 

5.5.1 Ownership. As between AEGIS and ARS, AEGIS is the owner of all right, title and interest in and to the Excipient, which shall be
included in AEGIS Technology and all existing patents and patent applications (“AEGIS Patents”) and; 
 (a) ARS shall not (and
shall not attempt or purport to) file or prosecute in any country any patent application which, discloses claims or uses or purports to claim or use the Excipient, or any information or other materials directly or indirectly derived therefrom
without the prior express written consent of AEGIS. 
 (b) If there is an Invention related to Excipient made or conceived by employees,
consultants, agents and others conducting work on behalf of ARS, whether alone or jointly with one or more employees, consultants, agents and others conducting work on behalf of AEGIS, ARS agrees to promptly disclose such invention to AEGIS and
supply AEGIS with a copy of the disclosure for AEGIS’ evaluation purposes. AEGIS shall have the sole right to determine what, if any, patent applications should be filed on such Invention. ARS hereby assigns to AEGIS all right, title and
interest in any such Inventions and shall execute, and require its and its Affiliates personnel and contractors to execute, any documents reasonably required to confirm AEGIS’ ownership of such Inventions, and any documents required to apply
for, maintain and enforce any patent rights in such Inventions. For the avoidance of doubt, such Inventions shall be AEGIS Technology and be subject to the terms of the License. 

  
 12 












 5.5.2 No Implied License. Except for the License, this License
Agreement shall not be construed to grant any license or other rights to ARS in the AEGIS Technology (other than Joint Inventions and Joint Patent Rights). 

5.6 Joint Inventions. “Joint Invention” shall mean: (a) any Invention that embodies or claims a Product,
including without limitation any invention relating to the use of Excipient for administering or stabilizing such Compound or any application of Excipient related to such Compound or Product; or (b) any Invention that is (i) made or
conceived jointly by one or more employees, consultants, agents and others conducting work on behalf of AEGIS and one or more employees, consultants, agents and others conducting work on behalf of ARS in connection with the performance of, and
during the term of, this License Agreement and/or the Supply Agreement and/or any of the Prior Agreements and (ii) is not an Invention subject to the provisions of Section 5.4.1 or Section 5.5.1 shall be a “Joint
Invention”. As between AEGIS and ARS, AEGIS shall be the owner of the Joint Inventions. 
 5.7 Invention Rights and
Obligations. In the event that any patent application(s) to one or more Invention(s) recites embodiments including an Excipient and/or Product, and claims to such embodiments can be pursued reasonably and in good faith, they will be pursued in
good faith by the Party taking responsibility for prosecution. In the fulfilment of their obligations under Sections 5.4.1(b), 5.5.1(b), and 5.6, the Parties agree to disclose such Inventions to each other, and to cooperate in the preparation and
prosecution of such applications pursuant to Sections 6.1 6.2 and 6.3. However, the Parties acknowledge that Inventions may be made which do not necessarily rely upon the Excipient, but in which we are nevertheless obligated to disclose the
inclusion of embodiments reciting an Excipient and/or Product, and/or may disclose data from studies which involved a Product; and the parties acknowledge that patent applications may be filed upon such Inventions which would support both claims
reciting Products included in an application containing claims not reciting Products. 
 For the avoidance of doubt, Inventions wherein
disclosure of data from studies which involved a Product are used to support claims that do not recite a Product or Excipient, they will be ARS Technology; the mention of an Excipient in the specification of an application does not make an Invention
a Joint Invention or Aegis Technology; however the mention of an Excipient in a claim does make an Invention a Joint Invention or Aegis Technology. However, ARS covenants to pursue claims reciting embodiments including an Excipient and/or Product in
good faith, if claims to such embodiments can be pursued reasonably and in good faith by either Party, either in the first application or one or more continuing applications. When such claims are presented in an application, ARS agrees that such
application will be owned by Aegis and Aegis may at its option assume primary responsibility for prosecution of the application. If ARS decides, in good faith and at its sole discretion, not to pursue such claims, Aegis shall have the option to
pursue such claims at its own expense. 
  

	6.	 PATENT RIGHTS 



6.1 Prosecution and Maintenance of AEGIS Patent
Rights. 
 6.1.1 AEGIS shall have the sole right (but not the obligation), [***] to prepare, file, prosecute and maintain the
AEGIS Patent Rights. AEGIS shall give ARS a reasonable opportunity, before filing, to review and comment on the text of any patent application within the AEGIS Patent Rights that covers the Product and shall provide ARS with a copy of such patent
application as filed, together with notice of its filing date and serial number. ARS shall, [***] cooperate with AEGIS, execute all lawful papers and instruments and make all rightful oaths and declarations as may be necessary in the preparation,
prosecution and maintenance of the AEGIS Patent Rights. 
 6.1.2 To the extent reasonably expected to adversely affect the AEGIS Patent
Rights or the Product, AEGIS shall [***] provide ARS with copies of correspondence or materials received from the PCT, the U.S. Patent & Trademark Office, or equivalent intellectual property regulatory authority in any other country. 

  
 13 












 6.1.3 If ARS reasonably believes that AEGIS may fail to make any required payments or take
any action required for the preparation, filing, prosecution, defense or maintenance of the AEGIS Patent Rights within a reasonable time, ARS shall provide AEGIS with written notice of such deficiency. If AEGIS fails to take any action required for
the preparation, filing, prosecution, defense or maintenance of the AEGIS Patent Rights within the shorter of (i) [***] of notice from ARS or (ii) [***] before the deadline for taking such action, ARS shall have the right to thereafter make any such
required payments or take any such required action, and deduct and offset such payments and any related costs and expenses from any milestone payments, royalties or other payments which may be required under this License Agreement or otherwise by
ARS, its Affiliates or sublicensees to AEGIS. 
 6.1.4 ARS shall reimburse AEGIS for actual costs incurred by AEGIS under the AEGIS Patent
Rights that are specific only to the Compound(s) and/or Product(s), including but not limited to all divisionals, continuations, continuations-in-part, reissues,
renewals, extensions or additions to any such patents and patent applications. 
 6.2 Prosecution and Maintenance of ARS Patent
Rights. ARS shall have the sole right (but not the obligation), [***] to prepare, file, prosecute and maintain the ARS Patent Rights. [***] AEGIS shall cooperate with ARS, execute all lawful papers and instruments and make all rightful oaths and
declarations as may be necessary in the preparation, prosecution and maintenance of the ARS Patent Rights. 
 6.3 Orange Book
Listings. ARS shall have the sole right (but not the obligation) to list any appropriate patents within the AEGIS Patent Rights, Joint Patent Rights, and ARS Patent Rights in the FDA Orange Book with respect to any Product. 

6.4 Enforcement. 
 6.4.1
Notification. Each Party shall notify the other Party of any infringement known to such Party of any AEGIS Patent Rights, ARS Patent Rights, or Joint Patent Rights for any Product for use in the Field and shall provide the other party with
the available evidence, if any, of such infringement. 
 6.4.2 Paragraph IV Claims. Except to the extent otherwise agreed by the
Parties in writing, the costs for any patent infringement litigation suit based on a Paragraph IV certification or any equivalent action outside the United States (i.e., an ANDA patent infringement litigation involving a patent listed pursuant to 21
U.S.C. Section 355(a)(2)(A)(iv)) involving the AEGIS Patent Rights, Joint Patent Rights or ARS Patent Right (to the extent covering a Product), brought by a third party where ARS is a named defendant, or by ARS where ARS is a named plaintiff,
in both cases irrespective of whether AEGIS is also named as a defendant or plaintiff (a “Paragraph IV Claim”), [***]. ARS shall have sole right to institute, prosecute and control such litigation. AEGIS shall cooperate fully in
such litigation, and in the case where ARS desires to bring such litigation, at ARS’s request, AEGIS agrees to join any such litigation to enforce the AEGIS Patent Rights or Joint Patent Rights against the third party or parties that made such
Paragraph IV certification. AEGIS shall have the right to approve any settlement that would adversely affect the AEGIS Patent Rights or AEGIS’s rights under this License Agreement or result in any liability or admission on behalf of AEGIS, such
approval not to be unreasonably withheld, conditioned or delayed. Any recovery realized as a result of such litigation shall be first applied to the prorata reimbursement of any reasonable litigation expenses of ARS and AEGIS under this
Section 6.4.2. Any remaining recovery realized from litigation brought pursuant to this Section 6.4.2 shall be treated as profits on sales of Products for purposes of determining Net Sales under this License Agreement, with AEGIS receiving
the applicable royalty for purposes of Section 4.4 on such deemed Net Sales, and ARS receiving the remainder. [***]. 

  
 14 












 6.4.3 AEGIS Patent Rights. Except as set forth in Section 6.4.2,
AEGIS, [***] shall have the right to determine the appropriate course of action to enforce the AEGIS Patent Rights or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce the AEGIS Patent Rights,
to control any litigation or other enforcement action and to enter into, or permit, the settlement of any such litigation or other enforcement action with respect to the AEGIS Patent Rights, and shall consider, in good faith, the interests of ARS in
so doing. If AEGIS does not, within [***] after receipt of any notice from ARS under Section 6.4.1, either abate the infringement of the AEGIS Patent Rights for any Product in the Field or file suit to enforce the AEGIS Patent Rights against at
least one infringing party, or, to the extent UAB has the first right to do so pursuant to the UAB Licensing Agreement, cause UAB to do so, ARS shall have the right, upon prior written notice to AEGIS, to take whatever action it deems appropriate to
enforce the AEGIS Patent Rights for any Product in the Field; provided, however, that, within [***] after receipt of notice of ARS’s intent to file such suit, AEGIS shall have the right to either (a) join such suit as a co-plaintiff or co-defendant with ARS and to fund up to [***] the costs of such suit or (b) request that ARS not take any such action or file such suit, and, if ARS
informs AEGIS that it intends to take such action or file such suit, AEGIS may submit such dispute to an independent third party arbiter, mutually agreed to by the Parties, with at least [***] experience in patent law, who shall determine within
[***] whether taking such action or filing such suit would have a reasonable likelihood of successfully enforcing patent rights covering Product(s) and/or Excipient(s) used in Product(s). Such arbiter’s determination shall be final and binding
on the Parties, and any dispute with respect to such arbiter’s determination shall not be submitted for resolution pursuant to Section 10.2. 

6.4.4 Joint Patent Rights. 

(a) ARS, [***] shall have the right to determine the appropriate course of action to enforce any Joint Patent Rights that claim Compound(s),
Product(s), and/or Excipient(s) used in Product(s) or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce such Joint Patent Rights, to control any litigation or other enforcement action and to
enter into, or permit, the settlement of any such litigation or other enforcement action with respect to such Joint Patent Rights, and shall consider, in good faith, the interests of AEGIS in so doing. If ARS does not, within [***] after receipt of
any notice from AEGIS under Section 6.4.1, either abate the infringement of such Joint Patent Rights or file suit to enforce such Joint Patent Rights against at least one infringing party, AEGIS shall have the right, upon prior written notice
to ARS, to take whatever action it deems appropriate to enforce such Joint Patent Rights; provided, however, that, within [***] after receipt of notice of AEGIS’ intent to file such suit, ARS shall have the right to join such suit
as a co-plaintiff or co-defendant with AEGIS and to fund up to [***] the costs of such suit. 

(b) AEGIS [***] shall have the right to determine the appropriate course of action to enforce the Joint Patent Rights that claims
Excipient(s), and do not claim Compound(s), Product(s), and/or Excipient(s) used in Product(s), or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce such Joint Patent Rights, to control


  
 15 












 
any litigation or other enforcement action and to enter into, or permit, the settlement of any such litigation or other enforcement action with respect to such Joint Patent Rights, and shall
consider, in good faith, the interests of ARS in so doing. If AEGIS does not, within [***] after receipt of any notice from ARS under Section 6.4.1, abate the infringement of such Joint Patent Rights or file suit to enforce such Joint Patent
Rights against at least one infringing party, ARS shall have the right, upon prior written notice to AEGIS, to take whatever action it deems appropriate to enforce such Joint Patent Rights; provided, however, that, within [***] after
receipt of notice of ARS’s intent to file such suit, AEGIS shall have the right to join such suit as a co-plaintiff or co-defendant with ARS and to fund up to [***]
the costs of such suit. 
 6.4.5 Cooperation; Recovery. ARS and AEGIS shall reasonably cooperate with each other in the planning and
execution of any action under Sections 6.4.3 or 6.4.4. The Party controlling any such enforcement action shall not settle the action or otherwise consent to an adverse judgment in such action that diminishes the rights or interests of the non-controlling Party without the prior written consent of the other Party. Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery realized as a result of such litigation
shall be first applied to the prorata reimbursement of any reasonable litigation expenses of ARS and AEGIS. Any remaining recovery realized from such litigation shall be treated as profits on sales of Products for purposes of determining Net Sales
under this License Agreement, with AEGIS receiving the applicable royalty for purposes of Section 4.4 on such deemed Net Sales, and ARS receiving the remainder. [***]. 

6.4.6 ARS Patent Rights. ARS, [***] shall have the right to determine the appropriate course of action to enforce the ARS Patent Rights
or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce the ARS Patent Rights, to control any litigation or other enforcement action and to enter into, or permit, the settlement of any such
litigation or other enforcement action with respect to the ARS Patent Rights. 
 6.5 FDA Matters. AEGIS covenants that it will not in
the performance of its obligations under this License Agreement use the services of any person debarred or suspended under 21 U.S.C. §335(a) or (b). AEGIS will not hire, as an officer or an employee any person who has been convicted of a felony
under the laws of the United States for conduct relating to the regulation of any drug product under the United States Food, Drug and Cosmetic Act. 
  

	7.	 CONFIDENTIALITY 



7.1 Confidentiality. During the term of this License Agreement and for a period of [***] following the expiration or earlier
termination hereof, each Party shall maintain in confidence the Confidential Information of the other Party, shall not use or grant the use of the Confidential Information of the other Party except as expressly permitted hereby, and shall not
disclose the Confidential Information of the other Party. Notwithstanding the previous sentence, the receiving Party may disclose the Confidential Information of the disclosing Party solely on a “need to know basis”, to Affiliates, and
their and each of the Parties’ respective directors, employees, contractors and agents, each of whom prior to disclosure must be bound by obligations of nondisclosure and non-use no less restrictive than
the obligations set forth in this Section 7; provided, however, that, in each of the above situations, the receiving Party shall remain responsible for any failure by any person or entity that receives Confidential Information
pursuant to this Section 7.1 to treat such Confidential Information as required under this 

  
 16 












 
Section 7. To the extent that disclosure to any person is authorized by this License Agreement, prior to disclosure, a Party shall obtain written agreement of such person to hold in
confidence and not disclose, use or grant the use of the Confidential Information of the other Party except as expressly permitted under this License Agreement. Each Party shall notify the other Party [***] upon discovery of any unauthorized use or
disclosure of the other party’s Confidential Information. 
 7.2 Terms of License Agreement. Neither party shall disclose any
terms or conditions of this License Agreement to any third party without the prior consent of the other Party; provided, however, that a Party may disclose the terms or conditions of this License Agreement, (a) on a need-to-know basis to its legal and financial advisors to the extent such disclosure is reasonably necessary, and (b) to a third party in connection with (i) an
equity investment in, or lending arrangement with, such third party, (ii) a sublicense, collaboration, co-promotion, strategic partnership, merger, consolidation or similar transaction by such Party, or
(iii) the sale of all or substantially all of the assets of such Party. In addition, ARS acknowledges that AEGIS is required and shall have the right to provide a copy of this License Agreement (and any subsequent amendment hereto), to UAB
under the confidentiality provisions of the UAB Licensing Agreement. AEGIS shall use reasonable efforts to enforce the confidentiality provisions of the UAB Licensing Agreement to the fullest extent permitted thereby so as to preserve the
confidentiality of this License Agreement and its terms, and shall not consent to any disclosure of this License Agreement or its terms to any third party by UAB. Notwithstanding the foregoing, either Party may disclose the fact that the Parties
have entered into this exclusive license agreement, and a general description of the AEGIS Patent Rights, the Product, and the Field covered by this License Agreement. 

7.3 Permitted Disclosures. The confidentiality obligations under this Section 7 shall not apply to any portion of Confidential
Information to the extent that a Party is required to disclose such portion by applicable Law, regulation or order of a governmental agency or a court of competent jurisdiction; provided, however, that such Party shall provide written
notice thereof to the other Party, consult with the other Party with respect to such disclosure and provide the other Party sufficient opportunity to object to any such disclosure or to request confidential treatment thereof. 

7.4 Publicity. If either Party wishes to make a public disclosure concerning this License Agreement, such Party shall provide the other

republish such disclosure in any other medium without again obtaining the prior approval of the other Party. 
  

	8.	 INDEMNIFICATION AND INSURANCE 



8.1 Indemnification by ARS. Except to the extent that AEGIS is obligated to indemnify ARS under Section 8.2, ARS shall indemnify
and hold harmless AEGIS, and its directors, officers, employees and agents, from and against all losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs, arising from any claims, demands, actions or other
proceedings by any third party arising 

  
 17 












 
from (a) the breach of any representation, warranty or covenant by ARS under this License Agreement; or (b) the Exploitation of the AEGIS Technology or Products by ARS, its sublicensees or
their respective Affiliates; provided, however, that such indemnification right shall not apply to any losses, liabilities, damages or expenses to the extent directly attributable to the negligence, reckless misconduct, or intentional
misconduct of a Party seeking indemnification under this Section 8.1. 
 8.2 Indemnification by AEGIS. AEGIS shall
indemnify and hold harmless ARS, and its directors, officers, employees and agents, from and against all losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs, arising from any claims, demands, actions or
other proceedings by any third party arising from (a) the breach of any representation, warranty or covenant by AEGIS under this License Agreement; (b) the Exploitation of the AEGIS Technology or Excipient(s) by AEGIS, its licensees
(excluding ARS) or their respective Affiliates; or (c) any claim of any third party that AEGIS willfully disclosed or made available to ARS any AEGIS Technology in violation of an obligation of AEGIS to such third party; provided,
however, that such indemnification right shall not apply to any losses, liabilities, damages or expenses to the extent directly attributable to the negligence, reckless misconduct, or intentional misconduct of a Party seeking indemnification
under this Section 8.2. 
 8.3 Procedure. A Party that intends to claim indemnification under this Section 8 (the
“Indemnitee”) shall promptly notify the other Party (the “Indemnitor”) in writing of any claim, demand, action or other proceeding for which the Indemnitee intends to claim indemnification; provided,
however, that the failure to provide written notice of such claim within a reasonable period of time will not relieve the Indemnitor of any of its obligation hereunder, except to the extent that the Indemnitor is prejudiced by such failure to
provide prompt notice. The Indemnitor shall have the right to participate in, and to the extent the Indemnitor so desires to assume the defense thereof with counsel selected by the Indemnitor; provided, however, that the Indemnitee,
shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing
interests between the Indemnitee and any other party represented by such counsel in such proceedings. The Indemnitor may not settle or otherwise consent to an adverse judgment in any such claim, demand, action or other proceeding, that diminishes
the rights or interests of the Indemnitee without the prior express written consent of the Indemnitee, which consent shall not be unreasonably withheld, delayed, or conditioned, unless (a) there is no finding or admission of any violation of
Law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnitee and (b) the sole relief provided is monetary damages that are paid in full by the Indemnitor.

	10.	 GENERAL PROVISIONS 



10.1 Governing Law. This License Agreement shall be governed by, interpreted and construed in accordance with the laws of the State of
California, without giving effect to any conflicts of law principles that would result in the application of the laws of any state other than the State of California. 

10.2 Arbitration. Any dispute, controversy or claim initiated by either Party arising out of, resulting from or relating to this
License Agreement, or the performance by either Party of any obligation under this License Agreement, whether before or after termination of this License Agreement, shall be finally resolved by binding arbitration. Whenever a Party shall decide to
institute arbitration proceedings, it shall give written notice to that effect to the other Party. Any such arbitration shall be conducted under the Commercial Arbitration Rules of the American Arbitration Association by a panel of three arbitrators
appointed in accordance with such rules. Any such arbitration shall be held in San Diego, California. The method and manner of discovery in any such arbitration proceeding shall be governed by the Commercial Arbitration Rules of the American
Arbitration Association. Each Party shall choose one (1) arbitrator within [***] after receipt of notice of the intent to arbitrate. Such arbitrators shall thereafter choose a third arbitrator within [***] of their appointment. If one or both
of the Parties fails to make a timely appointment of its arbitrator, then such missing arbitrator(s) will be appointed by the American Arbitration Association. The arbitrators shall have the authority to grant specific performance and to allocate
between the Parties the costs of arbitration in such equitable manner as they determine. The arbitrators shall make their award and decision by majority approval, which shall be made in accordance with the terms of this License Agreement and
applicable law. Judgment upon the award so rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order of enforcement, as the case may be. In no event shall a
demand for arbitration be made after the date when institution of a legal or equitable proceeding based upon such claim, dispute or other matter in question would be barred by the applicable statute of limitations. Notwithstanding the foregoing,
(i) either Party shall have the right, without waiving any right or remedy available to such Party under this License Agreement or otherwise, to seek and obtain from any court of competent jurisdiction any interim or provisional relief that is
necessary or desirable to protect the rights or property of such Party, pending the selection of the arbitrators hereunder or pending the arbitrators’ determination of any dispute, controversy or claim hereunder, and (ii) any and all
issues regarding the scope, construction, validity, and enforceability of one or more patents shall be determined in a court of competent jurisdiction under the local patent laws of the jurisdictions having issued the patent or patents in question.
Each of the Parties agrees that if certain material obligations under this License Agreement are not performed in accordance with their specific terms or are otherwise breached, (a) severe and irreparable damage would occur, (b) no
adequate remedy at law would exist and (c) damages would be difficult to determine. Each of the Parties agrees that, in such case, the injured Party or Parties shall be authorized and entitled to obtain from any court of competent jurisdiction
injunctive relief, whether preliminary or permanent, as well as any other relief permitted by applicable law, and the breaching Party shall waive any requirement that such Party or Parties post bond as a condition for obtaining any such relief. All
proceedings and decisions of the arbitrator(s) shall be deemed Confidential Information of each of the Parties, and shall be subject to Section 7. 

10.3 Modification; Waiver. This License Agreement may not be altered, amended, supplemented, or modified in any way except by a writing
signed by each Party. No waiver by a Party of any breach or default of any of the covenants or agreements herein set forth shall be deemed a waiver as to any subsequent and/or similar breach or default. The failure by either Party to take any action
or assert any right hereunder shall in no way be construed to be a waiver of such right, nor in any way be deemed to affect the validity of this License Agreement or any part hereof, or the right of a Party to thereafter enforce each and every
provision of this License Agreement. 

  
 20 












 10.4 Rights Under U.S. Bankruptcy Code. All rights and
licenses granted under or pursuant to this License Agreement by AEGIS are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses to intellectual property as defined under Section 101 of the
Bankruptcy Code. AEGIS agrees that ARS shall retain and may fully exercise its rights and elections under the Bankruptcy Code. 
 10.5
Assignment. Neither this License Agreement nor any right or obligation hereunder may be assigned or delegated, in whole or part, by either Party without the prior express written consent of the other; provided, however, that
(i) ARS may, without the written consent of AEGIS, assign this License Agreement and its rights and delegate its obligations hereunder in connection with the transfer or sale of all or substantially all of its business related to the Product,
or in the event of its merger, consolidation, change in control or similar transaction; (ii) AEGIS may, without the written consent of ARS, assign this License Agreement and its rights and delegate its obligations hereunder in connection with
the transfer or sale of all or substantially all of its business, or in the event of its merger, consolidation, change in control or similar transaction; and (iii) neither Party shall unreasonably withhold, delay or condition its consent to any
proposed assignment in any situation whereby all of its rights and entitlements are unaffected. Any permitted assignee shall assume all obligations of its assignor under this License Agreement. Any purported assignment in violation of this
Section 10.5 shall be void. For avoidance of doubt, AEGIS may have the Excipients manufactured by a third party contract manufacturer for the benefit of AEGIS and/or ARS, which shall not be deemed to be an assignment or delegation restricted by
this Section 10.5. 
 10.6 Independent Contractors. The relationship of the Parties is that of independent contractors. The
Parties are not deemed to be agents, partners or joint venturers of the others for any purpose as a result of this License Agreement or the transactions contemplated thereby. 

10.7 Further Actions. Each Party agrees to execute, acknowledge and deliver such further documents and instruments and to perform all
such other acts as may be necessary or appropriate in order to carry out the purposes and intent of this License Agreement. 
 10.8
Notices. Any notice, report, communication, or consent required or permitted by this License Agreement shall be in writing and shall be sent by a Party (a) by prepaid registered or certified mail, return receipt requested, (b) by
overnight express delivery service by a nationally recognized courier, or (c) via confirmed facsimile, followed within [***] by a copy mailed in the preceding manner, addressed to the other Party at the address shown below or at such other
address as such Party gives notice hereunder. Such notice will be deemed to have been given when delivered or, if delivery is not accomplished by some fault of the addressee, when tendered.

 10.9
No Implied Licenses. Only licenses and rights granted expressly herein shall be of legal force and effect. No license or other right shall be created hereunder by implication, estoppel or otherwise. 

10.10 Force Majeure. Nonperformance of a Party (other than for the payment of money) shall be excused to the extent that performance is
rendered impossible by strike, fire, earthquake, flood, governmental acts or orders or restrictions, failure of suppliers, or any other reason where failure to perform is beyond the reasonable control and not caused by the negligence, intentional
conduct or misconduct of the nonperforming Party; provided, however, that the nonperforming Party shall use commercially reasonable efforts to resume performance as soon as reasonably practicable. 

10.11 No Consequential Damages. EXCEPT WITH RESPECT TO A BREACH OF SECTION 7, IN NO EVENT SHALL A PARTY BE LIABLE FOR SPECIAL,
INCIDENTAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF THIS LICENSE AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, INCLUDING WITHOUT LIMITATION LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS LICENSE AGREEMENT, REGARDLESS OF
ANY NOTICE OF SUCH DAMAGES. NOTHING IN THIS SECTION 10.11 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDER SECTION 8. 

10.12 Complete Agreement. This License Agreement, the Supply Agreement, and the Prior Agreements, constitute the entire agreement
between the Parties regarding the subject matter hereof, and all prior and contemporaneous representations, understandings and agreements regarding the subject matter hereof, either written or oral, expressed or implied, are superseded and shall be
and of no effect; provided, however, that the terms of certain Mutual Confidentiality Agreement between AEGIS and ARS dated as of September 17, 2015, shall remain in full force and effect as to all confidential information
disclosed thereunder. 
 10.13 Counterparts. This License Agreement may be executed in counterparts, each of which shall be deemed to
be an original and together shall be deemed to be one and the same agreement. A facsimile copy of this License Agreement bearing the signature (original or facsimile or .PDF version) of both Parties shall be binding on the Parties. 

  
 22 












 10.14 Severability. If any provision of any provision of this License Agreement shall
be found by a court to be void, invalid, or unenforceable, the same shall be reformed to comply with applicable law or stricken if not so conformable, so as not to affect the validity or enforceability of this License Agreement; provided that
no such reformation or striking shall be effective if the result materially changes the economic benefit of this License Agreement to any Party. In the event that any provision of this License Agreement becomes or is declared by a court of competent
jurisdiction to be void, invalid, or unenforceable, and reformation or striking of such provision would materially change the economic benefit of this License Agreement to any Party, the Parties shall modify such provision in accordance with
Section 10.3 to obtain a legal, valid, and enforceable provision and provide an economic benefit to the Parties that most nearly effects the Parties’ intent on entering into this License Agreement. 

10.15 Headings. The captions to the several sections hereof are not a part of this License Agreement, but are included merely for
convenience of reference only and shall not affect its meaning or interpretation.

 WHEREAS, Section 4.4.5 of the Agreement provides that AEGIS will, upon written
notice by ARS, negotiate and agree with ARS in good faith a reduction of the royalty rate payable on Products on a country-by-country basis if the level of competition,
patent protection or the general commercial environment for such Product in such country materially affects the commercial viability of such Product in such country, and ARS has requested that AEGIS negotiate and agree to such a royalty rate
reduction in connection with royalties payable with respect to sales of Products by sublicensees; and 
 WHEREAS,
AEGIS and ARS now wish to amend the Agreement to modify the provisions of the Agreement regarding the royalty rate payable on Annual Net Sales of Products on the terms and subject to the conditions set forth herein.

	  	 	[***]	 

 4.4.3 The royalty percentage then applicable under this Section 4.4 to Net Sales of any
Product made in any country in the Territory shall be reduced by [***] from [***] to [***] if at the time of the sale of such Product in such country, the use, manufacture, offer for sale, sale and import of such Product in such county is not

in that country, then such [***] reduction shall be suspended. 
 The term “Competing Product” shall mean [***].

 4.4.5 If the level of competition, patent protection or the general commercial environment for such Product in such

of such royalty rates, as applicable to such Product in such country. 
 4.4.6 Third Party Licenses. 

(a) If ARS determines, in its reasonable judgment (subject to subpart b below), that the intellectual property rights of a
third party are necessary for the practice of any AEGIS Technology in accordance with this License Agreement, then the royalty and milestone amounts owed to AEGIS hereunder for Exploiting the AEGIS Technology in the country (or countries) where such
third party intellectual property rights are enforceable shall be subject to a credit reduction in an amount equal to [***] of the amount of any payments that ARS (or any of its sublicensees) pays such third party to use such third party

arbiter, mutually agreed to by the Parties, such agreement not to be unreasonably withheld, delayed, or conditioned, and such arbiter to have at least [***] experience in the biopharmaceutical industry overseeing drug development or patent law, who
shall determine within [***] whether, in the absence of rights granted by such third party, the practice of any AEGIS Technology in accordance with this License Agreement would likely or actually infringe or misappropriate such third party’s
intellectual property. Such arbiter’s determination shall be final and binding on the Parties, and any dispute with respect to such arbiter’s determination shall not be submitted for resolution pursuant to Section 10.2. Additionally,
any determination of likely or actual infringement shall be deemed a determination that such license to intellectual property rights of a third party is “necessary” for purposes of Section 4.4.6(a).

discount in order to induce the same third party to purchase any other products or services.

Section 4.4 is [***] of Annual Net Sales of Products, on a country-by- country and
