 2. Grant. 
 2.1 License. Subject to the terms of this Agreement, effective as of the Effective Date, Nuada grants to DARA a worldwide exclusive license, with

 4.2 Milestone Fees. DARA
shall pay the amounts detailed below within 120 days of the achievement of the corresponding milestones. 
  

				
	 Milestone
	  	Milestone Fee	 
	 The dosing of the first patient in the first Phase I Clinical Trial conducted by or on behalf of DARA or its Affiliates or Sublicensees with
respect to a Product.
	  	[	***]
		
	 The receipt of final results of the first Phase II Clinical Trial conducted by or on behalf of DARA or its Affiliates or Sublicensees with
respect to a Product, which results would permit the commencement of a Phase III Clinical Trial.
	  	[	***]
		
	 The receipt of final results of the first Phase III Clinical Trial conducted by or on behalf of DARA or its Affiliates or Sublicensees with
respect to a Product, which results would permit the submission of a new drug application to the Federal Drug Administration.
	  	[	***]
		
	 Marketing Authorization Approval in the first Major Market (defined below) for the sale of a Product.
	  	[	***]
		
	 Marketing Authorization Approval in the second Major Market for the sale of a Product.
	  	[	***]

 “Major Market” shall mean any of the United States, Japan or any country that is a
member of the European Union. 
 Each milestone payment above shall only be made once under this Agreement upon the initial accomplishment of
the relevant milestone by the first Product to achieve it, regardless of the number of Products or indications with respect thereto satisfying such milestone. 
 4.3 Running Royalties. 
 4.3.1 DARA shall pay Nuada, within 45 days following the end of each calendar
quarter, (i) [***] of Net Sales of all Products in countries in 

  

 5 

 
which there is a Valid Claim of a Patent claiming the use, sale, or manufacture of Products, until the aggregate of such Net Sales in all countries equals
[***], after which the royalty rate on any subsequent Net Sales in excess of [***] in the same calendar year will increase to [***], and (ii) [***] of Net Sales of all Products in countries in which there is not a Valid Claim of a Patent
claiming the use, sale, or manufacture of such Products. 
 4.3.2 Notwithstanding anything to the contrary in this Agreement, all royalties
payable under this Section 4.3 shall be paid on a country-by-country basis from the date of First Commercial Sale of a Product in a particular country. 
 4.4 Duration of Royalty Payments. All royalty obligations under this Agreement with respect to a particular Product shall expire at the end of the Term. Upon the expiration of all royalty obligations under this
Agreement, the licenses granted to DARA by Nuada under this Agreement will become non-exclusive, perpetual, irrevocable, fully-paid, and royalty-free. 
 4.5 Bundling. In the event that a Product is included as a “bundle” of products or services, DARA may discount Net Sales of such Product for purposes of calculating royalties due under this Agreement
by no more than the average percentage discount of all products subject to reimbursement by managed health care organizations, health insurers, and government agencies in a manner similar to that of the Product (“Comparable Products”) in a
particular “bundle,” calculated as [1-(A/B)] x 100, where “A” equals the total discounted price of the portion of a particular “bundle” consisting of such products, and “B” equals the sum of the undiscounted
bona fide list prices of each unit of every such product in such “bundle”. DARA will provide to Nuada, to the extent reasonably available or ascertainable, documentation establishing such average discount with respect to each
“bundle”. If DARA cannot so establish the average discount of a “bundle,” Net Sales for the “bundled” Product will be based on (i) the median selling price of the Product alone during the applicable calendar
quarter, if the Product is sold in a non-“bundled” form during such calendar quarter, or, if such Product is not sold in a non-“bundled” form during such calendar quarter, (ii) the undiscounted list price of the Product in
the “bundle”. If a Product in a “bundle” is not sold separately, and/or no bona fide list price exists for such Product or the other Comparable Products included in the “bundle,” then the Parties will negotiate in good
faith, based on a commercially reasonable determination of the relative values and/or imputed prices of the “bundled” product’s constituent products and Product, and imputed discounts provided with respect thereto, an alternative
determination of Net Sales with respect to the Product included in such “bundled” product consistent with the intent of this Section 4.5. 
 4.6 Combination Products. In the event a Product is sold which is a Combination Product, for purposes of determining payments due under Section 4.3, Net Sales of Combination Products shall be calculated by
multiplying the Net Sales of the Combination Product by the fraction A/(A+B), in which A is the Gross Selling Price (as defined below) of the Product when such Product is sold in substantial quantities containing a Licensed API as the sole API
during the applicable accounting period in which the Net Sales of the Product were calculated, and B is the Gross Selling Price of products incorporating solely the other APIs contained in the Combination Product sold separately in substantial
quantities during the applicable accounting 

  

 6 

 
period. In the event that no separate sale of either the Product containing a Licensed API as the sole API or products incorporating solely the other APIs of
the Combination Product are made during the accounting period in which the Net Sales were calculated, or if the Gross Selling Price for a product solely incorporating a particular API cannot be determined for the applicable accounting period, Net
Sales allocable to the Product and Combination Product shall be determined by mutual agreement reached in good faith by the Parties prior to the end of the accounting period in question based on a reasonably equitable method of determining same that
takes into account variations in potency, the relative contribution of each API in the Combination Product, and relative value to the end user of each API. For purposes of this Section, “Gross Selling Price” shall mean the gross price at
which a product incorporating such API as the sole API is sold to a Third Party, before discounts, deductions, credits, taxes or allowances. 
 4.7 Third Party Royalties. In the event that: 
 (a) a Product is deemed by a final, unappealable decision of a court of
competent jurisdiction to infringe a claim of a patent(s) owned or controlled by a Third Party in any given country and such infringement is directly related to the manufacture, use, practice, or sale of the Licensed Patents, and DARA, an Affiliate
thereof, or any Sublicensee licenses such patent(s) in settlement of such claims (“Infringement License”), or 
 (b) DARA, an
Affiliate thereof, or any Sublicensee determines, in its reasonable discretion, including (1) consultation with its patent counsel and (2) the provision to Nuada of a reasonable opportunity to discuss such determination, that it is
commercially, reasonably necessary to obtain a license to practice any Third Party’s rights in any given country in order to avoid, with respect to the Exploitation of a Product, (i) infringement or misappropriation of such Third
Party’s rights or (ii) infringement- or misappropriation-related litigation with respect to such Third Party rights, provided that, in either case, such possible infringement or misappropriation is directly related to the manufacture, use,
practice, or sale of the Licensed Patents (such license, a “Necessary License”), and, provided further, that DARA or its Affiliate or any Sublicensee provides Nuada a reasonable opportunity to discuss and evaluate the necessity of such
license, 
 then DARA may deduct up to one hundred percent (100%) of any fees, milestones or royalties paid by DARA, an Affiliate thereof, or any
Sublicensee to Third Parties for Infringement Licenses and Necessary Licenses (or such amounts paid by DARA, an Affiliate thereof, or any Sublicensee in settlement of any related infringement action) from the amounts otherwise due but not yet paid
to Nuada pursuant to Sections 4.2 and 4.3 hereof; provided, however, that, notwithstanding the foregoing, (i) the total amount due to Nuada under this Agreement with respect to any particular calendar quarter shall not be reduced by more than
fifty percent (50%) as a result of any adjustments under this Section 4.7 and (ii) any amounts not deducted in a calendar quarter as a result of the application of (a) and/or (b) above shall be carried forward for deduction
in the subsequent calendar quarter(s), subject to such fifty percent (50%) limitation in each case. 
 4.8 Compulsory Licenses.
Should a compulsory license be granted to a Third Party under the applicable Laws of any country under the Licensed Patents, or with respect to 

  

 7 

 
Products, DARA shall notify Nuada, including any material information concerning such compulsory license, prior to the grant of such compulsory license and
the running royalty rate payable hereunder for sales of Products in such country will be adjusted, if necessary, to match any lower royalty rate granted to such Third Party for such country with respect to the sales of such Products, provided that
during such periods such Third Parties sell or offer for sale under the compulsory license articles that compete with the Products then marketed and sold by DARA, its Affiliates, or Sublicensees in that country. 
 4.9 Tax Withholding. In addition, in the event any of the payments made by DARA pursuant to this Section 4 become subject to withholding
taxes under the Laws of any jurisdiction, such amounts payable to Nuada shall be reduced by the amount of taxes deducted and withheld, and DARA shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly
transmit to Nuada an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant Governmental Authority of all amounts deducted and withheld sufficient to enable Nuada to claim such payment of
taxes. Any such withholding taxes required under applicable Law to be paid or withheld shall be an expense of, and borne solely by, Nuada. DARA will provide Nuada with reasonable assistance, as requested by Nuada, at Nuada’s expense, to enable
Nuada to recover such taxes as permitted by Law. 
 4.10 Net Sales Report. Within 45 days following the end of each calendar quarter
following the First Commercial Sale, DARA will submit to Nuada a written report setting forth Net Sales (including the detailed computation thereof) on a country-by-country basis and Product-by-Product basis during such calendar quarter and calendar
year-to-date, total royalty and milestone payments due to Nuada, relevant sales and pricing data in support of royalties paid on Product sold as a “bundle” and Combination Products, and relevant information as necessary to support any
reduction in royalties paid resulting from the application of Section 4 hereof. 
 4.11 Payment Terms. All sums due to Nuada will
be payable in United States dollars. Except as otherwise set forth herein with respect to royalties and milestones, all other payments due hereunder will be paid within thirty (30) days following receipt of an invoice requesting such payment.

 4.12 Financial Records: Audits. DARA will keep at its corporate headquarters, accurate and complete records of milestones achieved
and Net Sales reasonably sufficient to determine the amounts due to Nuada under this Agreement. Such records will be retained by DARA for at least the three (3) calendar years following the end of the calendar year during which such Net Sales
or milestones were achieved. During normal business hours and with reasonable advance written notice to DARA, such records will be made available for inspection, copying, review and audit, at the request of Nuada, by an independent certified public
accountant appointed by Nuada and reasonably acceptable to DARA for the purpose of verifying the accuracy of accounting reports and payments pursuant to this Agreement. Such auditor will be required to enter into a confidentiality agreement with
DARA prior to performing the audit. The final report of the auditor, including methodology and supporting documentation, will be transmitted to both Parties. Such audits may not be performed by Nuada more than once per calendar year, All costs and
expenses incurred in performing any such audit will be paid by 

  

 8 

 
Nuada unless the audit discloses at least a five percent (5%) shortfall in payments made with respect to the audited time period(s), in which case DARA
will bear the costs and expenses of the audit. Nuada will be entitled to recover any shortfall in payments as determined by such audit. 
 5. Certain

 6. Patents. 
 6.1 Prosecution and Maintenance of Patents. DARA shall, as between the Parties, bear the cost of all future patent expenses associated with the preparation, filing, prosecuting, issuance, and maintenance of patents and patent
applications included in the Licensed Patents following the Effective Date. The Parties acknowledge and agree that the foregoing obligation shall include, but not be limited to, the costs and expenses associated with the Licensed Patents due in
December for filings in Australia, Canada, India, Japan, the United States and the European Union. Such filings, prosecution, and maintenance shall be by counsel of DARA’s choosing, under the primary control and direction of DARA, and shall be
in the name of Nuada. DARA shall keep Nuada advised as to such filing, prosecution, issuance, and maintenance by forwarding to Nuada copies of all material official correspondence (including, but not limited to, applications, office actions,
responses, etc.) relating thereto. Nuada shall have the right to comment and advise DARA as to the conduct of such filing, prosecution, and maintenance, provided, however, that DARA shall have the right to make the final decisions for all matters
associated with such filing, prosecution, and maintenance. In the event that DARA elects not to maintain or prosecute any patent or patent application within the Licensed Patents, (i) DARA shall give Nuada sixty (60) days prior written
notice of such election and (ii) Nuada will thereafter have the right, but not the obligation, upon written notice to DARA during such sixty (60) day period, at Nuada’s sole expense, to prosecute and/or maintain such patents or patent
applications, in light of the commercial interests of both parties, in the name of Nuada. 
 6.2 Indemnification. 
 6.2.1 Indemnification Claims. If (a) a claim is brought by a Third Party alleging patent infringement by DARA, its Affiliates, or their
Sublicensees with respect to the development, manufacture, use, sale, offer for sale or importation of Products, (b) a civil action is brought by a Third Party arising out of or relating to the practice of the Licensed Patents, or (c) any
Third Party challenges the validity of any claims of any Licensed Patent, each Party will give prompt written notice to the other Party of such claim (collectively, an “Indemnification Claim”). DARA will, at its sole cost and expense,
(i) defend such Indemnification Claim, (ii) assume all costs, expenses, damages and other obligations for payments incurred in connection with such Indemnification Claim, and (iii) indemnify and hold harmless Nuada and its managers,
members, Affiliates, successors and assigns from and against any and all damages, losses, liabilities and costs relating to or arising out of such Indemnification Claim. DARA shall be free to enter into a settlement, consent judgment, or other
voluntary disposition of such Indemnification Claim, provided that any settlement, consent judgment or other voluntary disposition of such Indemnification shall (x) contain a full and unconditional release of Nuada and its managers, members,
Affiliates, successors and assigns, (y) not subject Nuada to any liability or obligation and (z) not admit fault or wrongdoing on the part of Nuada. Nuada agrees to cooperate with DARA, at DARA’s expense, in any reasonable manner
deemed by DARA to be necessary in defending any such Indemnification Claim. DARA shall reimburse Nuada for any reasonable out of pocket expenses incurred in providing such assistance. Any recovery or damages received by DARA in any action or
settlement under this Section 6.2.1 with respect to the rights licensed under this Agreement shall be used first to reimburse the Parties for unreimbursed reasonable, documented expenses incurred in connection with such action, and the 

  

 11 

 
remainder shall be deemed Net Sales subject to royalties under Section 4.3. Notwithstanding the foregoing, either Party, at its expense, shall have the
right to be represented by counsel of its choice in any such proceeding controlled by the other Party. 
 6.2.2 Infringement of
Patents. In the event that DARA or Nuada becomes aware of actual or threatened infringement of any Licensed Patent during the Term, that Party will promptly notify the other Party in writing, which notice shall include any known material details
concerning such infringement or misappropriation. With respect to any alleged actual or threatened infringement of the Licensed Patents, DARA shall have the first and primary right, but not the obligation, to, in its sole discretion, to initiate,
prosecute, and control any action or legal proceedings, and/or enter into a settlement, including any declaratory judgment action, on its behalf or in Nuada’s name, if necessary, with respect to such alleged infringement or misappropriation.
If, within twelve (12) months of the notice above, DARA (i) shall have been unsuccessful in persuading the alleged infringer or misappropriator to desist, (ii) shall not have brought and shall not be diligently prosecuting an
infringement or misappropriation action, or (iii) has not entered into settlement discussions with respect to such infringement or misappropriation, or if DARA notifies Nuada that it has decided not to undertake any of the foregoing against any
such alleged infringer or misappropriator, then Nuada shall then have the right, but not the obligation, to bring suit to enforce the Licensed Patents, or to seek relief with respect to such misappropriation, at its own expense. In any such
litigation brought by DARA, DARA shall have the right to, if and as reasonably necessary or useful in such action, use and sue in Nuada’s name, and Nuada shall cooperate reasonably, as requested by DARA and at DARA’s expense (which expense
shall be reasonable and documented). The Party pursuing or controlling any action against an alleged infringer or misappropriator pursuant to the foregoing (the “Controlling Party”) shall be free to enter into a settlement, consent
judgment, or other voluntary disposition of any such action, provided, however, that (i) the Controlling Party shall consult with the other Party (the “Secondary Party”) prior to entering into any settlement thereof and
(ii) any settlement, consent judgment or other voluntary disposition of such actions which (1) materially limits the scope, validity, or enforceability of any Licensed Patent (if Nuada is the Secondary Party), (2) subjects the
Secondary Party to any non-indemnified liability or obligation, or (3) admits fault or wrongdoing on the part of Secondary Party, must be approved in writing by Secondary Party, such approval not to be unreasonably withheld. Secondary Party
shall provide the Controlling Party notice of its approval or denial of such approval within ten (10) business days of any request for such approval by the Controlling Party, provided that (i) in the event Secondary Party wishes to deny
such approval, such notice shall include a written description of Secondary Party’s reasonable objections to the proposed settlement, consent judgment, or other voluntary disposition and (ii) Secondary Party shall be deemed to have
approved such proposed settlement, consent judgment, or other voluntary disposition in the event it fails to provide such notice within such ten (10) business day period. Any recovery or damages received by the Controlling Party with respect to
the infringement or misappropriation of DARA’s rights under the Licensed Patents shall be used first to reimburse the Parties for unreimbursed reasonable, documented expenses incurred in connection with such action, and the remainder shall be
deemed Net Sales and subject to the payment of royalties to Nuada under Section 4.3 above. Notwithstanding the foregoing, the Secondary Party, at its expense, shall have the right to be represented by counsel of its choice in any such
proceeding.

 6.3 Assistance. For purposes of this Section 6, the Party not bringing suit or defending any
suit will, at the expense of the other Party, execute such legal papers or take such actions necessary for the prosecution or defense of such suit as may be reasonably requested by the Party bringing suit or defending any suit. 
 7. Term and Termination. 
 7.1 Term. Unless
otherwise mutually agreed to by the Parties or earlier terminated as provided herein, this Agreement will commence on the Effective Date and will end upon expiration of the Term. Except in the event of termination under Section 7.2, the
licenses granted by Nuada to DARA pursuant to Section 2 will be considered fully-paid and will become perpetual, irrevocable, and non-exclusive upon expiration of the Term. 
 7.2 Termination for Material Breach. Either Party may, without prejudice to any other remedies available to it at law or in equity, terminate this
Agreement in the event that the other Party materially breaches in the performance of its obligations under this Agreement; provided that, if such breach can be cured, the breaching Party will have thirty (30) days after receipt of written
notice thereof from the non-breaching Party to cure such breach. Any such termination will become effective at the end of such 30-day period unless the breaching Party has cured any such breach prior to the expiration of such 30-day period.
Notwithstanding the foregoing, in the event of a breach by DARA of the provisions of Section 3.2, such breach shall be considered to be a material breach for purposes of this Section 7.2, and DARA’s right to cure any such breach shall
be limited only to its first breach of Section 3.2, and DARA shall not have the right to cure any subsequent breach of the provisions of Section 3.2. 
 7.3 Effects of Termination. 
 73.1 Effect of Termination for Material Breach. 
 (a) Material Breach by DARA. In the event this Agreement is terminated by Nuada pursuant to Section 7.2 for material breach by DARA, all
licenses granted by Nuada to DARA or its Affiliates under this Agreement will terminate, subject to Section 7.3.2, provided that, notwithstanding the foregoing, DARA and its Affiliates shall have the privilege, subject to the payment of
royalties as required under Section 4, of (i) completing the manufacture of any Products in the process of manufacture as of the effective date of such termination (the “Termination Date”), (ii) selling such Products
and all finished Products in DARA’s or its Affiliates’ possession or under their control as of the Termination Date for a period of one year following the Termination Date upon commercially reasonable conditions, and (iii) completing
performance of all contracts entered into with Third Parties prior to the Termination Date for the marketing, sale, or manufacture of Products for a period of one year following the Termination Date. 
 (b) Material Breach by Nuada. In the event this Agreement is terminated by DARA pursuant to Section 7.2 for material breach by Nuada all
licenses granted by Nuada to DARA or its Affiliates under this Agreement prior to termination will survive, subject to DARA’s continued obligation to pay milestones and royalties to Nuada hereunder. 
  

 13 

 7.3.2 Sublicenses. If this Agreement is terminated by Nuada for DARA’s breach, pursuant to
Section 7.2, all sublicenses granted to Third Parties regarding the intellectual property rights licensed to DARA by Nuada hereunder prior to such termination shall survive and be automatically assigned to, and enforceable by, Nuada upon such
termination, subject to the payment of any future amounts due thereunder to Nuada, in order to permit such Sublicensees’ continued quiet enjoyment of their rights thereunder in accordance with the terms thereof; provided, however, that such
assignment shall not subject Nuada to any obligations or liabilities in excess of those imposed by this Agreement. 
 7.4 Accrued Rights;
Surviving Obligations. Except as provided elsewhere, termination or expiration of this Agreement for any reason will be without prejudice to any rights that will have accrued to the benefit of any Party prior to such termination or expiration.
Such termination or expiration will not relieve any Party from obligations which are expressly or by implication intended to survive termination or expiration of this Agreement, including but not limited to, definitions, rights to payment, and
Sections 6.2, 6.3, 7, 8, 9, and 10 and will not affect or prejudice any provision of this Agreement which is expressly or by implication provided to come into effect on, or continue in effect after, such termination or expiration. 
 8. Confidential Information. 
 8.1 Definition.
“Confidential Information” means confidential or proprietary information, data or know-how, whether provided in written, oral, visual or other form, provided by one Party (the “Disclosing Party”) to the other Party (the
“Receiving Party”) in connection with this Agreement, including but not limited to, the terms of this Agreement and information relating to the Disclosing Party’s existing or proposed research, development efforts, patent
applications, business or products. Confidential Information will not include any such information that: (i) is already known to the Receiving Party (other than under an obligation of confidentiality) at the time of disclosure (as evidenced by
written records of the Receiving Party); (ii) is or becomes generally available to the public other than through any act or omission of the Receiving Party; (iii) is disclosed to the Receiving Party without obligation of confidentiality by a
Third Party who had the legal right to disclose such information; or (iv) is independently discovered or developed by or on behalf of the Receiving Party without the use or benefit of the Confidential Information of the Disclosing Party (as
evidenced by written records of the Receiving Party). 
 8.2 Confidentiality. The Receiving Party will keep in confidence all
Confidential Information of the Disclosing Party with the same degree of care it employs to maintain the confidentiality of its own Confidential Information, but no less than a reasonable degree of care. The Receiving Party will not use such
Confidential Information for any purpose other than in performance of or exercise of its rights under this Agreement or disclose the same to any other Person other than to such of its employees, agent, or subcontractors who have a need to know such
Confidential Information to implement the terms of or exercise of its rights under this Agreement. A Receiving Party will advise any employee, agent or subcontractor who receives Confidential Information of such obligations, and the Receiving Party
will ensure that all such agents, employees and subcontractors comply with such obligations as if they had been a Party 

  

 14 

 
hereto. The Receiving Party will be liable for breach of this Section 8 by any of its employees, agents or subcontractors. Notwithstanding the
foregoing, nothing in this Section 8 shall limit or preclude DARA’s use or disclosure of Nuada’s Confidential Information in its reasonable efforts to Exploit the Licensed Patents. 
 8.3 Permitted Disclosure and Use. The Receiving Party will have the right to disclose Confidential Information if, in the reasonable opinion of
the Receiving Party’s legal counsel, such disclosure is required by Law or the rules of any stock exchange, provided that, to the extent reasonably practicable, the Receiving Party gives adequate prior notice of such disclosure to the
Disclosing Party to permit the Disclosing Party to intervene and to request protective orders or other confidential treatment. The Receiving Party will cooperate reasonably with any such efforts by the Disclosing Party. 
 8.4 Confidentiality of this Agreement. The terms of this Agreement will be deemed Confidential Information of each Party. Either Party may
disclose the terms of this Agreement (i) if, in the opinion of its counsel, such disclosure is required by Law, provided that such Party will seek appropriate confidentiality of those portions of the Agreement for which confidential treatment
or a protective order is typically permitted by the relevant Governmental Authority or (ii) as necessary in connection with any financing, merger, strategic partnership, or other similar transaction, subject to the execution of confidentiality
agreement with the Third Party. 
 8.5 Return. Upon termination of this Agreement, the Receiving Party will return or destroy all
documents or other media containing Confidential Information of the Disclosing Party. 
 8.6 Remedies. Money damages will not be an
adequate remedy if this Section 8 is breached and, therefore, either Party may, in addition to any other legal or equitable remedies, seek an injunction or other equitable relief against such breach or threatened breach without the necessity of
posting any bond or surety. 
 8.7 Survival. This Section 8 will survive the expiration or termination of this Agreement for a
period of ten (10) years. 
 9. Indemnification; Limitation of Liability. 
 9.1 Indemnification by DARA. Subject to Sections 9.3 and 9.4, DARA will defend, indemnify and hold harmless Nuada and its Affiliates and each of
their officers, directors, shareholders, employees, successors and assigns from and against all actions, suits, proceedings, hearings, investigations, charges, complaints, claims, demands, injunctions, judgments, orders, decrees, rulings, damages,
dues, penalties, fines, costs, amounts paid in settlement, liabilities, obligations, losses, taxes, liens, diminutions in value, costs, expenses and fees (including reasonable attorneys’ fees and expenses, and the costs of investigation
incurred in defending against or settling any such matter and any amounts paid in settlement thereof) (collectively, “Losses”) arising out of claims made by Third Parties, to the extent arising out of (i) DARA’s negligence or
willful misconduct in performing any of its obligations or exercising its rights under this Agreement, (ii) breach by DARA of any of its representations, warranties, covenants, 

  

 15 

 
or agreements under this Agreement or (iii) the Exploitation of Products by DARA, its Affiliates, agents, subcontractors or Sublicensees, except to the
extent resulting from the negligence or willful misconduct, breach of this Agreement, or failure to comply with applicable Laws by Nuada or its Affiliates, sublicensees, officers, directors, employees, contractors, agents, other representatives,
successors, or assigns. 
 9.2 Indemnification by Nuada. Subject to Sections 9.3 and 9.4, Nuada will defend, indemnify and hold
harmless DARA and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns from and against all Losses arising out of claims made by Third Parties, to the extent arising out of (i) Nuada’s
negligence or willful misconduct in performing any of its obligations or exercising its rights under this Agreement or (ii) breach by Nuada of any of its representations, warranties, covenants or agreements under this Agreement, except to the
extent resulting from the negligence or willful misconduct, breach of this Agreement, or failure to comply with applicable Laws by DARA or its Affiliates, sublicensees, officers, directors, employees, contractors, agents, other representatives,
successors, or assigns. 
 9.3 Procedure for Indemnification. A Party which intends to seek indemnification under this Section 9
(such Party hereinafter referred to as the “Indemnitee”) for a Loss in respect to a Claim by a Third Party (“Third Party Claim”), will promptly give written notice thereof to the Party from whom indemnification is sought (such
other Party hereinafter referred to as the “Indemnitor”) within a reasonable period of time after the assertion of such Third Party Claim; provided, however, that the failure to provide written notice of such Third Party Claim within a
reasonable period of time will not relieve Indemnitor of any of its obligations hereunder, except to the extent that Indemnitor is materially prejudiced by such failure. Indemnitor may assume the complete control of the defense, compromise or
settlement of any Third Party Claim (provided that any settlement of any Third Party Claim that (i) subjects Indemnitee to any non-indemnified liability or (ii) admits fault or wrongdoing on the part of Indemnitee will require the prior
written consent of such Indemnitee, provided such consent will not be unreasonably withheld), including, at its own expense, employment of legal counsel, and at any time thereafter Indemnitor will be entitled to exercise, on behalf of Indemnitee,
any rights which may mitigate the extent or amount of such Third Party Claim; provided, however, that if Indemnitor will have exercised its right to assume control of such Third Party Claim, Indemnitee (i) may, in its sole discretion and at its
own expense, employ legal counsel to represent it (in addition to the legal counsel employed by Indemnitor) in any such matter; (ii) will, at Indemnitor’s own expense, make available to Indemnitor those employees, officers, contractors,
and directors of Indemnitee whose assistance, testimony or presence is necessary or appropriate to assist Indemnitor in evaluating and in defending any such Third Party Claim; provided, however, that any such access will be conducted in such a
manner as not to interfere unreasonably with the operations of the businesses of Indemnitee; and (iii) will otherwise fully cooperate with Indemnitor and its legal counsel in the investigation and defense of such Third Party Claim. 

9.4 Consequential Damages. EXCEPT WITH RESPECT TO BREACHES OF SECTION 8, BREACHES OF THE LICENSES GRANTED HEREUNDER, OR CLAIMS FOR PATENT
INFRINGEMENT, IN NO EVENT WILL EITHER PARTY OR THEIR AFFILIATES BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE, TREBLE 

  

 16 

 
OR CONSEQUENTIAL DAMAGES INCLUDING LOST PROFITS, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER LEGAL THEORY; PROVIDED, HOWEVER, THAT, NOTWITHSTANDING THE
FOREGOING, THIS LIMITATION WILL NOT LIMIT THE INDEMNIFICATION OBLIGATION OF SUCH PARTY IN RESPECT OF THIRD PARTY LOSSES UNDER THE PROVISIONS OF THIS SECTION 9. 
 9.5 Setoffs. If DARA shall be entitled to be indemnified for Losses in accordance with this Section 9 or, as determined by a court of competent jurisdiction, suffers damages as a result of a breach of this
Agreement by Nuada, the parties hereby agree that DARA shall set off the amount of such Losses or damages (subject to the limitations of Section 9.4) from existing or future amounts, if any, owed to Nuada pursuant to this Agreement, and nothing
in this Agreement shall be construed to require or permit DARA to seek indemnification from Nuada or other legal relief prior to offsetting any such Losses or damages from amounts owed to Nuada hereunder. 
 10. Miscellaneous. 
 10.1 Public Announcements.
Except as may be expressly permitted under this Section 10.1 or required by applicable Laws or the rules of any stock exchange, neither Party will make any public announcement of any information regarding this Agreement without the prior
written approval of the other Party, which approval will not be unreasonably withheld, conditioned, or delayed, provided that, notwithstanding the foregoing, DARA shall have the right to identify Nuada as the licensor and to disclose the terms of
this Agreement to actual or prospective investors, strategic partners, investment bankers, acquirors, acquisition targets, and regulatory authorities, in connection with its financing, regulatory, licensing, development, stockholder relations, and
other business activities or that it may deem to be required in any prospectus, offering memorandum, or other document or filing prepared in connection with its compliance obligations under applicable securities Law or other applicable Law or
regulation. 
 10.2 Relationship of the Parties. Neither Party will have any responsibility for the hiring, termination or
compensation of the other Party’s employees or for any employee benefits of such employee. No employee or representative of a Party will have any authority to bind or obligate the other Party to this Agreement in any manner whatsoever, or to
create or impose any contractual or other liability on the other Party without such Party’s approval. For all purposes, DARA’s legal relationship under this Agreement to Nuada will be that of independent contractor. This Agreement is not a
partnership agreement and nothing in this Agreement will be construed to establish a relationship of partners or joint venturers between the Parties. 
 10.3 Expenses. The fees and expenses of both DARA and Nuada incurred in connection with the negotiation, preparation and execution of this Agreement shall be paid as follows: (a) DARA shall pay the first
$8,000 of such fees and expenses, whether incurred by DARA or Nuada, (b) Nuada shall pay the next $4,000, whether incurred by DARA or Nuada, and (c) any such amounts in excess of $12,000 shall be paid one-half by DARA and one-half by
Nuada. 
 10.4 Force Majeure. The occurrence of an event which materially interferes with the ability of a Party to perform its
obligations or duties hereunder which is not within the reasonable 

  

 17 

 
control of the Party affected or any of its Affiliates, and which could not with the exercise of due diligence have been avoided (“Force Majeure
Event”), including but not limited to, fire, accident, strike, riot, civil commotion, act of God, inability to obtain raw materials, delay or errors by shipping companies or change in law, will not excuse such Party from the performance of its
obligations or duties under this Agreement, but will merely suspend such performance during the Force Majeure Event. The Party subject to a Force Majeure Event will promptly notify the other Party of the occurrence and particulars of such Force
Majeure Event and will provide the other Party, from time to time, with its estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so affected will use commercially reasonable efforts to avoid or
remove such causes of nonperformance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty will promptly recommence. The Party subject to the Force Majeure Event will
not be liable to the other Party for any direct, indirect, consequential, incidental, special, punitive, exemplary or other damages arising out of or relating to the suspension or termination of any of its obligations or duties under this Agreement
by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 10.4. 
 10.5 Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of North Carolina, excluding that body of law known as choice of law, and shall be
binding upon the parties hereto in the United States and worldwide. All disputes with respect to this Agreement shall be brought and heard either in the North Carolina state courts located in Wake County, North Carolina, or the federal district

Affiliates or to a successor to all or substantially all of the assets or business of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or other similar transaction. Any assignment in violation of this
provision is void and without effect. This Agreement will be binding upon and inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns.

for the Licensed Product or other product or service (e.g. achievement of market share or placement on a formulary tier), or (iii) otherwise where the resulting price concessions or discounts are greater than those which would have been
available had the bundled products or services been purchased separately or outside the bundled arrangement), Licensee may with notice to Licensor discount the bona fide list price of a Licensed Product by the average percentage discount of all
products or services of Licensee and/or its Affiliates or Third Party sublicensee in a particular “bundle”, calculated as follows: 
  

									
		 	 Average percentage
 discount on a

particular “bundle”

If a Licensed Product in a “bundle” is not sold separately, and no bona fide list price exists for such Licensed Product, Licensee and Licensor shall negotiate in good faith a reasonable imputed list price for such Licensed Product and Net
Sales with respect thereto shall be based on such imputed list price. 
 Notwithstanding anything herein to the contrary, the transfer of a
Licensed Product to an Affiliate, sublicensee, or other Third Party, at no cost or for a price that is not materially in excess of Licensee’s cost of manufacturing or procuring such Licensed Product, (i) in connection with the research,

under Section 2.1 to one or more Third Parties upon prior written approval by Bayer, such approval not to be (i) unreasonably withheld, delayed, or conditioned or (ii) conditioned on the payment of any additional consideration to
Bayer or amendment of any economic terms of this Agreement in favor of Bayer. Licensee shall provide Licensor a written copy of any proposed sublicense for Bayer’s review and approval, provided that Licensee may redact any portions of such
sublicenses (or amendments) disclosing sublicensees’ proprietary information, technology, or research, development, or commercialization plans as reasonably necessary to comply with any confidentiality obligations to such sublicensee. Bayer

territory shall be deemed a “sublicensee” of Licensee hereunder for such territory. 
 2.2A Right of First Negotiation.
Prior to Licensee’s first entering into material negotiations concerning a sublicense of Licensee’s rights hereunder to any Third Party for purposes of enabling such Third Party to Commercialize any Licensed Product(s), Licensee shall
provide Licensor written notice of its intent to pursue such a sublicense and Licensor shall have the right, if it provides written notice to Licensee within thirty (30) days of such notice, to exclusively negotiate with Licensee for period of
sixty (60) days following its notice to Licensee within the aforementioned initial thirty (30) day period, during which negotiations both parties shall exercise commercially reasonable good faith efforts to reach an agreement concerning

exercise such right of negotiation within the thirty (30) day period described above, Licensee shall have no further obligation to Licensor under this Section 2.2A. Further, once Licensee has complied with this Section 2.2A once under
this Agreement, Licensee shall have no further obligations under this Section 2.2A and shall be free to sublicense any or all of its rights under this Agreement without providing any further or future right to negotiation for the benefit of
Licensor.

 Confidential 
  

 
entitled to a complete duplicate of or complete access to (as such Noninvolved Party deems appropriate), any such intellectual property and all embodiments

Party (a) upon any such commencement of a bankruptcy proceeding upon written request therefore by the Noninvolved Party, unless the Involved Party elects to continue to perform all of its obligations under this Agreement or (b) if not
delivered under (a) above, upon the rejection of this Agreement by or on behalf of the Involved Party upon written request therefor by the Noninvolved Party. The foregoing is without prejudice to any rights the Noninvolved Party may have
arising under the U.S. Bankruptcy Code or other applicable law.

 Confidential 
  

 
[***] No multiple royalties shall be payable because the manufacture, use, or sale of any Licensed Product is, or shall be, covered by more than one Valid
Claim contained in the Licensed Patents. A royalty shall be payable under this Section 3.2 only once with respect to any particular Licensed Product. 
 3.3 Third Party Royalties. In the event that (a) a Licensed Product is deemed by a final, unappealable decision of a court of competent jurisdiction to infringe a claim of a patent(s) owned or controlled

any sublicensee of either of the foregoing determines that it is commercially, reasonably necessary or advisable to pay royalties to a Third Party to obtain a license to practice any Third Party’s rights in order to manufacture, use,
Commercialize or Develop a Licensed Product in any given country of the Territory, or (c) it would be necessary to obtain a license to practice any Third Party’s rights that could improve, enhance, or modify a Licensed Product in any given
country of the Territory, as determined by Licensee, an Affiliate thereof, or any sublicensee of either of the foregoing, then Licensee may deduct an amount equal to fifty percent (50%) of any fees, milestones or royalties due to such Third
Parties for such rights (or such amounts paid by Licensee, its Affiliate, or any sublicensee of either of the foregoing in settlement of any infringement action) (collectively, all of the foregoing, “Third Party Royalties”) from the
any amounts due Licensor hereunder. 
 3.4 Compulsory Licenses. Should a compulsory license be granted, or be the subject of a
possible grant, to a Third Party under the applicable laws of any country in the Territory under the Licensed Patents, the Party receiving notice thereof or otherwise becoming aware thereof shall promptly notify the other Party thereof, including
any material information concerning such compulsory license, and the royalty rate payable hereunder for sales of Licensed Products in such country will be adjusted to match any lower royalty rate granted to such Third Party for such country with
respect to the sales of such Licensed Products, subject to any adjustments pursuant to Section 3.3 above. 
 3.5 Milestone
Payments. Licensee shall pay Licensor the following amounts within ninety (90) days of Licensee, an Affiliate, or any sublicensee of either of the foregoing achieving the indicated milestone:

the foregoing
	  	[	***]
		
	 Regulatory Approval of a Secondary Product (or a Diabetes Product for a Secondary Indication) in a Major Market for the benefit of Licensee,
an Affiliate thereof, or a sublicensee of either of the foregoing

in a Major Market of a Secondary Product (or a Diabetes Product for a Secondary Indication) by or on behalf of Licensee, an Affiliate thereof, or a sublicensee of either of the foregoing
	  	[	***]

 The first Diabetes Product is subject to the Diabetes Product milestones set forth above. In the
event the first Diabetes Product fails to achieve Regulatory Approval, Licensee may develop a second replacement Diabetes Product being obligated to pay only those milestone payments described above not already paid to Licensor with respect to the
first Diabetes Product. Thus, milestone payments for the first successful Diabetes Product shall not exceed [***], regardless of how many Diabetes Products are evaluated. A “successful” product means, for purposes of this Section 3.5,
Regulatory Approval in a Major Market. 
 As described above, a Secondary Indication for the first successful Licensed Product shall be
considered a Secondary Product for purposes of the milestone payments described above and shall be paid at [***] the original milestones established above with respect to the Diabetes Product for a total of no more than [***]. A Secondary
Indication, however, is not a Secondary Product. 
 A Secondary Product is subject to [***] of the original milestone payments set forth
above with respect to the Diabetes Product (for a total not to exceed [***]). In the event the 

  

 11 

 Confidential 
  

 
initial Second Product is not successful, the Licensee may develop other replacement Secondary Products, paying only those milestones not previously paid for
the development of a Secondary Product. In no instance shall total milestone payments for Secondary Products exceed [***]. 
 Additional
Licensed Products after the first two successful Licensed Products (or success of the Diabetes Product and a Secondary Indication for such Diabetes Product) shall be subject to royalty payments only and shall not be subject to milestone development
payments. 
 Notwithstanding anything to the contrary, the total amounts payable to Licensor under this Section 3.5 shall not exceed
[***], and each milestone above shall only be payable once, with respect to the first Diabetes Product or Secondary Product, as applicable, to achieve such milestone. 
 3.6 Minimum Payments. Beginning with respect to calendar year 2009, if the total amounts payable under this Section 3 with respect to Net Sales and milestones achieved during a particular calendar year
(“Earned Payments”) do not equal or exceed the amount noted below for such calendar year, Licensee shall pay Licensor, in addition to any Earned Payments for such calendar year, an amount equal to the difference between such Earned
Payments and the amount noted below for such calendar year. Any amounts paid under this Section 3.6 shall be fully creditable against, and deducted from, any milestone payments due under Section 3.5.

 As an example of the payment contemplated by this Section 3.6, if Net Sales during calendar
year 2014 total [***], and no milestones triggering any payment under Section 3.5 are achieved during calendar year 2014, Licensee shall pay Licensor, in addition to royalty payments of [***] under Section 3.2 (assuming there are no
royalty adjustments pursuant to Sections 3.3 or 3.4), [***] under this Section 3.6. 
 Notwithstanding anything to the contrary,
Licensor’s sole and exclusive remedy with respect to Licensee’s failure to pay, as the total amount paid under this Section 3 with respect to a particular calendar year, the amounts listed above shall be the right, following sixty
(60) days’ written notice to Licensee of such failure without cure, to terminate this Agreement and Licensee’s rights hereunder. Payments due under this Section 3.6 shall be made within sixty (60) days of the end of the
relevant calendar year, consistent with Section 3.7. 
 3.7 Payments and Payment Reports. Except as otherwise provided herein,
all royalties and payments due under this Section 3 shall be paid within sixty (60) days of the end of the relevant calendar quarter for which the applicable Net Sales occur, subject, with respect to Net Sales by Third Party sublicensees,
to any longer reporting periods which may be agreed to 

  

 12 

 Confidential 
  

 
by Licensee or its Affiliates with respect to such sublicensees. Each royalty payment shall be accompanied by a statement stating (as applicable) the number,
description, and aggregate Net Sales, by country, of each Licensed Product sold during the relevant calendar quarter by Licensee and its Affiliates and Third Party sublicensees and detailing the calculation of royalties and milestones due for such
calendar quarter. 
 3.8 Payment Method. All payments due under this Agreement to Licensor shall be made by check or bank wire
transfer in immediately available funds to an account designated by Licensor. All payments hereunder shall be made in the legal currency of the United States of America, except as provided in Section 3.10. 
 3.9 Taxes. It is understood and agreed between the Parties that any payments made under this Agreement are exclusive of any value added or similar
tax (“VAT”) imposed upon such payments. For the case charging or imposition of VAT is legally required due to (i) Licensor’s sale to, merger with, acquisition by, or assignment of this Agreement to an Affiliate or Third Party
located in, or otherwise subject to the laws of, a jurisdiction other than Licensor’s Original Jurisdiction, or any other action of Licensor that causes it or this Agreement to become subject to the laws of another jurisdiction, or (ii) a
change in the laws of Licensor’s potential future jurisdiction, and such VAT will not be fully refundable for the Licensee this VAT will be reimbursed by the Licensor to the extent not refundable. In addition, in the event any of the payments
made by Licensee pursuant to Section 3 become subject to withholding taxes under the laws of any jurisdiction, such amounts payable to Licensor shall be reduced by the amount of taxes deducted and withheld, and Licensee shall pay the amounts of
such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Licensor an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant Governmental Authority of all
amounts deducted and withheld sufficient to enable Licensor to claim such payment of taxes. No deduction shall be made, or a reduced amount shall be deducted, to the extent the Licensee is timely furnished with necessary documents certifying,
consistent with applicable laws, rules, and regulations, that the payment is exempt from tax or subject to a reduced tax rate. Any such withholding taxes required under applicable law to be paid or withheld shall be an expense of, and borne solely
by, Licensor. 
 Each Party will provide the other Party with reasonable assistance to enable the other Party to recover any of the
above-described taxes as permitted by law, provided that if a Party reasonably incurs any Third Party costs in rendering such assistance (including but not limited to reasonable, documented attorneys’ fees), the Party requesting such assistance
shall promptly reimburse the assisting Party for such costs. 
 3.10 Blocked Currency. In each country where the local currency is
blocked and cannot be removed from the country under such country’s applicable law, royalties accrued in that country shall be paid to Licensor in the country in local currency by deposit in a local bank designated by Licensor, unless the
Parties otherwise agree. 
 3.11 Sublicenses. For avoidance of doubt, the Parties agree that in the event that Licensee grants
licenses or sublicenses to Third Parties to sell Licensed Products, Licensee shall use commercially reasonable efforts to include in such licenses or sublicenses an obligation for the licensee or sublicense to account for and report its sales of
Licensed Products on a basis reasonably sufficient to enable Licensee to pay Licensor the royalties due under this Agreement. 
  

 13 

 Confidential 
  

 3.12 Foreign Exchange. Conversion of sales recorded in local currencies to U.S. dollars will
be performed in a manner consistent with Licensee’s reasonable practices used to prepare its audited financial statements for external reporting purposes, provided that such practices use a widely accepted source of published exchange rates.
Licensee shall notify Licensor of the conversion method(s) used by Licensee. 
 3.13 Interest. If Licensee fails to make any payment
when due to Licensor under this Agreement, then interest shall accrue on a daily basis at a rate equal to the thirty (30) day U.S. dollar LIBOR rate effective for the date that payment was due, as published by The Wall Street Journal.
The obligation to pay interest on such late payments set forth herein shall not be construed to limit or restrict Licensor’s right to terminate this Agreement in accordance with the terms and conditions of Section 8.3. 
 3.14 Records; Audits. Licensee shall keep or cause to be kept such records as are required to determine, in a manner consistent with generally
accepted accounting principles in the United States, the sums or credits due under this Agreement. At the request (and expense) of Licensor, Licensee and its Affiliates and sublicensees shall permit an independent certified public accountant
appointed by Licensor and reasonably acceptable to Licensee, at reasonable times not more than once a year and upon reasonable notice, to examine only those records as may be necessary to determine, with respect to any calendar year ending not more
than three (3) years prior to Licensor’s request, the correctness or completeness of any royalty report or payment made under this Agreement. Licensor shall promptly provide a copy of the results of any such audit to Licensee. Licensor
shall bear the full cost of the performance of any such audit, unless such audit discloses an underpayment exceeding five percent (5%) of the amount actually due hereunder, in which case Licensee shall bear the reasonable, documented cost of
the performance of such audit. Licensee shall promptly pay to Licensor the amount of any underpayment of royalties revealed by an examination and review. Any overpayment by Licensee of royalties or any other amount paid to Licensor revealed by an
examination and review shall, in Licensee’s sole discretion, (i) be fully-creditable against future payments under this Agreement or (ii) refunded to Licensee within ten (10) business days of its request.

 4.1 Licensee shall, during the Term, use Diligent Efforts to pursue the research, development, and commercialization of at least one Licensed Product. As between the Parties, Licensee will own all Regulatory
Approvals and Regulatory Filings for each country in the Territory for Licensed Products.

	 	b.	any communications with Governmental Authorities and the minutes of any meetings with Governmental Authorities relating to any Licensed Product; 

  

	 	c.	DMFs and any trial, drug, device, or other master files relating to any Licensed Product, including copies of all case report forms; 

  

	 	d.	copies of all listings and tables of results from the clinical trials relating to any Licensed Product;

Products or conducting preclinical studies and clinical trials and other Development activities with respect to each Licensed Product, and the Commercialization of Licensed Products. 
 Further, for a period of sixty (60) months following the Effective Date, the Licensor shall promptly provide such technical assistance to Licensee
as Licensee requests regarding the Licensed Technology, Licensed Patents, Licensed Products, and Licensor’s efforts with respect to Regulatory Filings or its seeking of Regulatory Approval for any Licensed Product(s). Such technical assistance
and transfer shall be limited to no greater than two hundred forty (240) person-hours. 
 4.3 Within ten (10) business days
of any request of Licensee made in writing during the first year following the Effective Date, Licensor shall provide Licensee with, as requested by Licensee, all or a portion of the materials described on Schedule 4.3 (the “Existing

	5.	PATENT PROSECUTION AND MAINTENANCE. 

 5.1 Unless and until Licensee exercises its rights under Section 5.3 below, Licensor shall be responsible for, and be obligated to diligently
pursue the preparation, filing, prosecution (including but not limited to, by conducting interferences, oppositions and reexaminations or other similar proceedings), maintenance (by timely paying all maintenance fees, renewal fees and other
applicable fees and costs), and extension of any Patents within the Licensed Patents. Licensor will regularly advise Licensee of the status of all pending patent applications in the Licensed Patents, including any related hearings or other
proceedings, and, at Licensee request, will provide Licensee with copies of all documentation concerning such applications, including all correspondence to and from any Governmental Authority. Licensor shall consult with and obtain written consent
from Licensee prior to abandoning any Licensed Patent or any claim contained therein, which consent shall not be unreasonably withheld, delayed, or conditioned. Licensor will solicit Licensee’s advice and review of such applications and
important prosecution matters related thereto in reasonably sufficient time prior to filing thereof, and will take into account Licensee’s reasonable comments related thereto. The reasonable, documented costs incurred following the Effective
Date with respect to the filing, prosecution, and maintenance of Licensed Patents shall be borne by Licensee, subject to Sections 5.2 and 5.4 below. 
 5.2 Licensor will provide reasonable advance written notice of any required foreign patent filings and associated fees. Licensee must thereafter inform Licensor in writing which foreign countries, if any, in
which Licensee desires patent protection and Schedule 1.24 will be amended in writing to reflect those designations. Licensor may elect to seek patent protection in countries not so designated by Licensee, in which case Licensor shall be
responsible for expenses attendant thereto as described in Section 5.4. However, in such instances, such patent applications will not be Licensed Patents, Schedule 1.24 shall be deemed to be so amended accordingly, if necessary, and
Licensee forfeits all rights under this Agreement to such patent applications and resulting patents in such countries. 
 5.3 Licensee
shall have the right to assume primary responsibility for all activities associated with the prosecution of Licensed Patents under this Agreement, provided that it first provides Licensor with written notice of its desire to assume such
responsibilities and obtains Licensor’s written approval of the legal counsel that Licensee shall retain for such purposes, such approval not to be unreasonably withheld. It is understood and agreed that in the event Licensee assumes such
responsibilities, it shall keep Licensor advised as to the status of the Licensed Patents by providing Licensor, in a timely manner, with copies of all official documents and correspondence relating to the prosecution, maintenance, and validity of
the Licensed Patents. Licensee shall consult with Licensor in such prosecution and maintenance, shall diligently seek advice of Licensor on all matters pertaining to the Licensed Patents, shall diligently seek reasonably strong and broad claims
under the Licensed Patents, and shall not abandon prosecution of any Licensed Patents or any of the claims of the Licensed Patents without first notifying Licensor in a timely manner of Licensee’s intention and reason therefor, and providing
Licensor with reasonable opportunity to assume responsibility for prosecution and maintenance of the appertaining Licensed Patents (which thereafter shall be subject to the other provisions of this Section 5 that regard Licensed Patents). All
decisions with respect to the prosecution of the Licensed Patents by Licensee pursuant to this Section 5.3 shall be made by Licensee. Licensee’s 

  

 16 

 Confidential 
  

 
obligations under this Section 5.3 shall include, without limitation, an obligation to inform Licensor in a timely manner (no less than thirty
(30) days prior to the appertaining filing deadlines) that Licensee will not pursue patents in any non-U.S. country so that Licensor may pursue such patents if it so desires. In such case, upon the date of such filing of such patent
applications by Licensor, such patents and patent applications shall not be considered Licensed Patents, Licensee shall be deemed to have forfeited all rights under this Agreement to such patent applications and resulting patents, and Schedule
1.24 shall be deemed to be so amended. For avoidance of doubt, it is understood that Licensee shall assume direct and full responsibility for payment of expenses it incurs as a result of its assumption of responsibility for prosecution of
Licensed Patents under this Section 5.3. 
 5.4 If Licensee provides Licensor with written notification that it will no longer
support the filing, prosecution, or maintenance of a specified patent(s) and/or patent application(s) within the Licensed Patents, then Licensee’s responsibility for fees and costs related to the filing, prosecution, and maintenance of such
subject Licensed Patents will terminate sixty (60) days after Licensor’s receipt of such written notification. However, in such instances, sixty (60) days after Licensor’s receipt of written notification, such patents and/or
patent applications will no longer be included in Licensed Patents (and Schedule 1.24 shall be deemed to be so amended accordingly), and Licensee surrenders all rights under this Agreement to such patents, patent applications, and any patents
issuing therefrom. 
 5.5 Patent Term Extensions. Licensee shall promptly notify Licensor of the issuance of each Regulatory Approval
and, where reasonably possible and reasonably useful or materially valuable in the commercialization of Licensed Products, use Diligent Efforts to apply or enable Licensor to apply for a patent term extension, adjustment or restoration,
supplementary protection certificate, or other form of market exclusivity conferred by applicable laws, rules, regulations, or guidelines (collectively, “Patent Term Extensions”) in the relevant country of the Territory. Licensor
shall, to the extent reasonably possible and reasonably useful or valuable in the commercialization of Licensed Products, use commercially reasonable efforts to, if and as requested by Licensee, obtain (or assist the Licensee in obtaining) all
available Patent Term Extensions. The Parties shall cooperate with each other in obtaining Patent Term Extensions wherever and whenever applicable, reasonably possible to obtain, and reasonably useful or valuable in the commercialization of Licensed
Products 
  

	6.	PATENT INFRINGEMENT. 

 6.1 Notice. If either Party becomes aware of any actual, potential, or alleged infringement of any Licensed Patents, such Party shall give to the other Party prompt and reasonably detailed written notice of such actual, potential, or
alleged infringement. 
 6.2 Infringement of Licensed Patents. With respect to any actual, potential, or alleged infringement of the
rights granted to Licensee hereunder with respect to the Licensed Patents, Licensee shall have the first and primary right, but not the obligation, to, in its sole discretion, initiate, prosecute, and control any action or legal proceedings, and/or
enter into a settlement, including any declaratory judgment action, on its behalf or in Licensor’s name, if necessary, with respect to such alleged infringement. If, within twelve (12) months of the notice above, Licensee (i) shall
have been unsuccessful in persuading the alleged infringer to desist, (ii) 

  

 17 

 Confidential 
  

 
shall not have brought and shall not be diligently prosecuting an infringement action, or (iii) has not entered into settlement discussions with respect
to such infringement, or if Licensee notifies Licensor that it has decided not to undertake any of the foregoing against any such alleged infringer, then Licensor shall then have the right to bring suit to enforce the rights granted to Licensee
hereunder with respect to Licensed Patents at its own expense. In any such litigation brought by Licensee, Licensee shall have the right to use and sue in Licensor’s name and join Licensor as a party to such litigation, and Licensor shall
cooperate reasonably, as requested by Licensee and at Licensee expense (which expense shall be reasonable). 
 6.3 Infringement of Third
Party Rights. If a claim is brought by a Third Party alleging patent infringement by Licensee, Licensor, their Affiliates, or their sublicensees with respect to the manufacture, use, sale, offer for sale or importation of Licensed Products, or
any third party challenges the validity or enforceability of any claims of any Licensed Patents, each Party will give prompt written notice to the other Party of such claim. The Parties shall promptly use commercially reasonable efforts to consult
in good faith to develop a commercially reasonable strategy or strategies, which shall take into account the reasonable economic interests of both parties, for jointly and/or cooperatively responding to any such infringement claim or challenge to
the validity or enforceability of any Licensed Patents. If (i) the efforts of the Parties are unable to agree upon such a strategy within fifteen (15) business days of the notice described above or (ii) Licensor does not use
commercially reasonable efforts to consult in good faith with Licensee concerning such a strategy, as described above, Licensee shall have the first and primary right (but not the obligation) at its own expense to defend, control the defense of,
and/or settle any such infringement claim against Licensee, its Affiliates, or their sublicensees or challenge of the validity or enforceability of the Licensed Patents, using counsel of its own choice. Licensor shall cooperate reasonably, as
requested by Licensee and at Licensee expense (which expense shall be reasonable). With respect to any such defense. If, within six (6) months of the expiration of the fifteen (15) business day period noted above, Licensee (i) shall
have been unsuccessful in defending such a challenge to the validity or enforceability of any claim of the Licensed Patents, (ii) shall not have brought and shall not be diligently prosecuting litigation with respect to such challenge, or
(iii) has not entered into settlement discussions with respect to such challenge, or if Licensee notifies Licensor that it has decided not to undertake any of the foregoing with respect to such challenge, then Licensor shall then have the
right, at its expense, to defend any Third Party challenge to the validity or enforceability of any claims in the Licensed Patents (but not any other claim or allegation referenced above except with respect to any defense of any Third Party claim of
infringement by Licensor), and Licensee shall cooperate, as reasonably requested by Licensor and at Licensor expense, with respect to any such defense. 
 6.4 Litigation Control. Unless otherwise agreed upon by the Parties in writing with respect to any joint or cooperative strategy developed under Section 6.3, the Party pursuing or controlling any action or
defense under Section 6.2 or 6.3 (the “Controlling Party”) shall be free to enter into a settlement, consent judgment, or other voluntary disposition of any such action or defense, provided, however, that (i) the
Controlling Party shall consult with the other Party (the “Secondary Party”) prior to entering into any settlement thereof and (ii) any settlement, consent judgment or other voluntary disposition of such actions which
(1) materially limits the scope, validity, or enforceability of any Licensed Patents or, if Licensee is the Secondary Party, Patents owned or controlled by Licensee, (2) subjects the Secondary Party to any non-indemnified liability or
obligation, or (3) admits fault or wrongdoing on the part of Secondary Party must, in 

  

 18 

 Confidential 
  

 
each case, be approved in writing by Secondary Party, such approval not to be unreasonably withheld. The Secondary Party shall provide the Controlling Party
notice of its approval or denial of such approval within ten (10) business days of any request for such approval by the Controlling Party, provided that (i) in the event Secondary Party wishes to deny such approval, such notice shall
include a written description of Secondary Party’s reasonable objections to the proposed settlement, consent judgment, or other voluntary disposition and (ii) Secondary Party shall be deemed to have approved such proposed settlement,
consent judgment, or other voluntary disposition in the event it fails to provide such notice within such ten (10) business day period. Any recovery or damages received by the Controlling Party with respect to the infringement of the Licensed
Patents shall be used first to reimburse the Parties for unreimbursed reasonable, documented expenses incurred in connection with such action, and the remainder shall be split ninety percent (90%) to Controlling Party and ten percent
(10%) to Secondary Party. Notwithstanding the foregoing, the Secondary Party, at its expense, shall have the right to be represented by counsel of its choice in any such proceeding. 
 6.5 Reimbursement. Unless otherwise agreed upon by the Parties in writing with respect to any joint or cooperative strategy developed under
Section 6.3, the Controlling Party shall invoice the Secondary Party for any reasonable, documented costs incurred that are to be borne by the Controlling Party pursuant to this Section 6. The Controlling Party shall pay the Secondary
Party such amounts within thirty (30) days of its receipt of any such invoice. 
 6.6 Trademarks. Licensee may, in its sole
discretion, select trademarks for the Licensed Product and shall own all such trademarks. To the extent Licensee pursues trademarks for Licensed Products, as between the parties, Licensee shall have the sole responsibility for the filing,
prosecution and maintenance of registrations of product trademarks for Licensed Products, at its sole expense. 
  

	7.	CONFIDENTIALITY 

 7.1 Treatment of
Confidential Information. The Parties agree that during the Term, and for a period of five (5) years after the end of the Term, a Party receiving Confidential Information of the other Party will (a) maintain in confidence such
Confidential Information to the same extent such Party maintains its own proprietary industrial information of similar kind and value (but at a minimum each Party shall use commercially reasonable efforts), (b) not disclose such Confidential
Information to any Third Party without prior consent of the other Party, and (c) not use such Confidential Information for any purpose except those permitted by this Agreement.

 7.5 Publicity. Licensee shall be entitled, in its sole discretion, to make public announcements regarding its Development and Commercialization of
Licensed Products. In addition, Licensee may make a public statement concerning the Agreement or the progress of the Licensed Products where such statement is required by law, applicable stock exchange regulation or legal proceedings. In connection
with any filing described in the foregoing sentence, Licensee shall use commercially reasonable efforts to obtain confidential treatment of trade secret 

  

 20 

 Confidential

consent of the other Party. 
 7.6 Publications. Neither Licensor nor its employees, contractors, investigators, directors, officers,
or shareholders shall publish or present any information with respect to any Licensed Product or Licensed Technology without Licensee’s prior consent (which may be withheld in Licensee’s sole and final discretion), except as required under
Section 7.3(d). 
  

	8.	TERM AND TERMINATION 

 8.1 Term. This Agreement shall become effective on the Effective Date and shall continue on a Licensed Product-by-Licensed Product and country-by-country basis until the earlier of (i) expiration of the
Royalty Term with respect to the applicable Licensed Product in the applicable country or (ii) the effective date of termination pursuant to Section 8.2 or 8.3 (the “Term”). Upon expiration of this Agreement pursuant
clause (i) above, Licensee and its Affiliates shall have the perpetual, unrestricted, fully-paid, royalty-free right, with rights of sublicense, to make, have made, use, sell, offer for sale, and import Licensed Products in the applicable

 8.3 Mutual Termination
Rights. Either Party will have the right to terminate this Agreement upon the following: 
 (a) It reasonably believes that the other
Party is in material breach of this Agreement, in which case the non-breaching Party may deliver written notice of such material breach to the other Party, such notice to describe in detail the nature of such breach. The allegedly breaching Party
shall have sixty (60) days from receipt of such notice to cure such breach. Any such termination shall become effective at the end of such 60-day period unless the breaching Party has cured any such breach or default prior to the expiration of
such 60-day period (or, if such default is capable of being cured but cannot be cured within such 60-day period, the breaching Party has commenced and diligently continued actions to cure such default provided always that, in such instance, such
cure must have occurred within one hundred twenty (120) days after notice thereof was provided to the breaching Party by the non-breaching Party to remedy such default); or 
 (b) the other Party is generally unable to meet its debts when due, or makes a general assignment for the benefit of its creditors, or there shall have
been appointed a receiver, trustee or other custodian for such Party for or a substantial part of its assets, or any case or

 Confidential 
  

 
proceeding shall have been commenced or other action taken by or against such Party in bankruptcy or seeking the reorganization, liquidation, dissolution or
winding-up of such Party or any other relief under any bankruptcy, insolvency, reorganization or other similar act or law, and any such event shall have continued for sixty (60) days undismissed, unstayed, unbonded and undischarged. In such
circumstances, the other Party may, upon notice to such Party, terminate this Agreement, such termination to be effective upon such Party’s receipt of such notice. 
 8.4 Effects of Termination. 
 (a) Except as set forth in Section 8.1, upon any termination of
this Agreement, all licenses granted by Licensor to Licensee under this Agreement shall terminate and Licensee and its Affiliates shall cease Development and Commercialization of all Licensed Products, provided that, notwithstanding the foregoing,
Licensee and its Affiliates shall have the privilege, subject to the payment of royalties as required under Section 3, of (i) completing the manufacture of any Licensed Products in the process of manufacture as of the effective date of
such termination (the “Termination Date”), (ii) selling such Licensed Products and all finished Licensed Products in Licensee’s possession or under its control as of the Termination Date for a period of one year following

or (2) requiring the use of technology claimed in the Licensed Patents or Licensed Products for a period of one year following the Termination Date. Notwithstanding any provision herein to the contrary, no termination of this Agreement by
Licensor shall be construed as a termination of any valid sublicense granted by Licensee, Its Affiliates, or its sublicensees with respect to the rights granted under this Agreement. Upon termination of this Agreement by Licensor each sublicense
shall, to the extent not imposing obligations on Licensor in excess of those contained herein, be automatically assigned to Licensor. 
 (b)
Termination of this Agreement shall not terminate the obligations of Licensee to make any payments then owing through the date of termination or the obligations of confidentiality imposed on either party. 
 (c) The remedies set forth in this Section 8 are not exclusive, and shall not limit any other legal or equitable remedies that are available to the
parties.

proceedings or causes of action (“Claims”) brought by a Third Party against a Party or its Representatives based on: (a) material breach by the indemnifying Party of this Agreement, (b) failure to comply with any
applicable law, rule, or regulation by such indemnifying Party in connection with the performance of its obligations hereunder or the exercise of licenses or rights conveyed hereunder, or (c) gross negligence or willful misconduct by such
indemnifying Party, its Affiliates, or their respective employees, contractors or agents, except, in each case, to the extent such Damages arise from the gross negligence or willful misconduct of the other Party or its Representatives. 

10.2 Indemnification by Licensee. Licensee hereby agrees to indemnify, defend and hold Licensor and its Representatives harmless from and
against any Damages resulting from Claims brought by a third party against Licensor or its Representatives resulting directly or indirectly from Licensee’s Development, Commercialization, manufacture, use or sale of Licensed Products, except to
the extent such Damages are subject to indemnification by Licensee pursuant to Section 10.1. 
 10.3 Notification. In the event
that any Third Party asserts a claim with respect to any matter for which a Party (the “Indemnified Party”) is entitled to indemnification hereunder (a “Third Party Claim”), then the Indemnified Party shall promptly
notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the
Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby. Indemnifying Party may assume the complete control of the defense, compromise or settlement of any Third Party
Claim (provided that any settlement of any Third Party Claim that (i) subjects Indemnified Party to any non-indemnified liability or (ii) admits fault or wrongdoing on the part of Indemnified Party will require the prior written consent of
such Indemnified Party, provided such consent will not be unreasonably withheld),

 Confidential 
  

 
including, at its own expense, employment of legal counsel, and at any time thereafter Indemnifying Party will be entitled to exercise, on behalf of
Indemnified Party, any rights which may mitigate the extent or amount of such Third Party Claim; provided, however, that if Indemnifying Party has exercised its right to assume control of such Third Party Claim, Indemnified Party
(i) may, in its sole discretion and at its own expense, employ legal counsel to represent it (in addition to the legal counsel employed by Indemnifying Party) in any such matter, and in such event legal counsel selected by Indemnified Party
will be required to reasonably confer and cooperate with such counsel of Indemnifying Party in such defense, compromise or settlement for the purpose of informing and sharing information with Indemnifying Party; (ii) will, at Indemnifying
Party’s own expense, make available to Indemnifying Party those employees, officers, contractors, and directors of Indemnified Party whose assistance, testimony or presence is necessary or appropriate to assist Indemnifying Party in evaluating
and in defending any such Third Party Claim; provided, however, that any such access will be conducted in such a manner as not to unreasonably interfere with the operations of the businesses of Indemnified Party; and (iii) will
otherwise fully cooperate with Indemnifying Party and its legal counsel in the investigation and defense of such Third Party Claim. 
 10.4 Exclusion of Damages. IN NO EVENT SHALL EITHER PARTY OR ITS AFFILIATES BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES, WHETHER BASED UPON A CLAIM OR ACTION OF
CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE, ARISING OUT OF THIS AGREEMENT, UNLESS SUCH DAMAGES ARE DUE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE LIABLE PARTY. NOTWITHSTANDING ANYTHING TO THE CONTRARY, THE
FOREGOING SHALL NOT BE CONSTRUED TO LIMIT THE INDEMNITY OBLIGATIONS SET FORTH IN SECTIONS 10.1 AND 10.2 ABOVE OR EITHER PARTY’S LIABILITY FOR PATENT INFRINGEMENT OR BREACH OF SECTIONS 2.1 OR 7.

the Parties other than as are set forth herein and therein. 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.

 11.2 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 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 force majeure continues and the
nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the

 11.10 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent

or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering into this Agreement may be realized.

matter for a particular period of time.
