Agreement between Company and any of its Affiliates. Unless agreed to in writing by KemPharm, each Company Sublicense Agreement shall be consistent with the terms and conditions of this Agreement, and Company shall be solely responsible for all of
its Affiliates’ and Sublicensees’ activities thereunder and any and all failures by its Affiliates and Sublicensees to comply with the terms of this Agreement in connection with their exercise of any of the rights or licenses granted to
Company hereunder. 
 2.2 Non-Exclusive Cross-Licenses. Each Party hereby grants the
other Party a royalty-free, perpetual, worldwide, non-exclusive license, with the right to grant further sublicenses (through multiple tiers), under such Party’s rights and interest in the Joint IP, to
research, develop, make, have made, sell and otherwise commercially exploit compounds and products other than the Compounds and Products. 

2.3 Negative Covenant. Company covenants that it will not, and further that it will not authorize any of its Affiliates or
Sublicensees to, use or practice any Licensed IP outside the scope of the license granted to it under Section 2.1(a). In addition, each Party covenants that it will not, and further that it will not authorize any of its Affiliates or
sublicensees to, use or practice any Joint IP outside the scope of the license granted to it under Section 2.2.

(d) Notwithstanding anything to the contrary in this Agreement, the restrictions placed on a Restricted Party and its Affiliates in
Section 2.5(a) will not apply to a Restricted Party or any of its Affiliates to the extent such Party or any of its Affiliates acquires, through an equity or asset purchase, merger, consolidation, license or other transaction (other than a
Change of Control), in each case, whether in a single transaction or a series of related transactions, a Competing Product (other than in a transaction or series of transactions where [*****] of such transaction or series of transactions),
provided that [*****]; and provided, further, that the Restricted Party or its Affiliate, as the case may be, either (i) [*****] with respect to [*****], or (ii) [*****] for the remainder of the period in
Section 2.5(a). Such Restricted Party shall not be in violation of Section 2.5(a), provided that such Restricted Party or its Affiliate complies with [*****], on the one hand, and the [*****], on the other hand, and the

 2.6 Additional Product Option. KemPharm hereby grants to Company an exclusive option to include Additional
Products as Product(s) under this Agreement (the “Additional Product Option”). KemPharm shall keep Company reasonably informed as to its Development of each Additional Product through completion of Phase 1 proof-of-concept study of such Additional Product. Upon completion of such a study, KemPharm shall provide Company with a report and data package setting forth the results of
such study in the form of Exhibit C hereto. KemPharm and Company shall negotiate in good faith regarding the economic terms of such Additional Product, and Company may exercise the Additional Product Option with respect to an Additional
Product by delivering a written exercise notice to KemPharm within [*****] days after the receipt of such report and data package for such Additional Product (the “Additional Product Option Period”). If KemPharm and
Company reach agreement on the terms for such Additional Product and Company timely exercises the applicable Additional Product Option, such Additional Product shall automatically be deemed a Product and licensed to Company under the terms and
conditions of this Agreement, as amended to incorporate the negotiated terms for such Additional Product as mutually agreed between KemPharm and Company. For clarity, the scope of the exclusive license under Section 2.1(a), as applied to any
Additional Product that becomes a Product pursuant to this Section 2.6 shall include the right to Develop and manufacture any Compound associated with such Additional Product in the Field in the Territory. If Company fails to exercise the
applicable Additional Product Option before the expiration of the applicable Additional Product Option Period, then KemPharm shall have the right to continue the Development and Commercialization of such Additional Product, either on its own or in
collaboration with a Third Party. 

  
 13 













 2.7 Right of First Refusal. Without limiting any Company’s rights or
KemPharm’s obligations under Section 2.6, KemPharm hereby grants Company a right of first refusal (“Right of First Refusal”) to acquire, license, and/or commercialize any Additional Product for which Company does not elect
the Additional Product Option (each, a “ROFR Product”), respectively, and such right of first refusal may be exercised only once for each ROFR Product and shall expire upon acceptance of the NDA for each such ROFR Product.
Company’s Right of First Refusal shall be available for a period of no greater than [*****] Business Days following receipt of written notice from KemPharm of the existence of a bona fide offer to acquire, license, and/or
commercialize any such ROFR Product from a Third Party. KemPharm shall disclose the material terms of the offer to Company. If Company exercises its Right of First Refusal and agrees to acquire, license and/or commercialize such ROFR Product on the
same economic terms as offered by such Third Party, then the ROFR Product will be deemed a Product and licensed to Company under the terms and conditions of this Agreement, except that the Parties will amend this Agreement as appropriate to
incorporate the economic terms offered by such Third Party. If Company fails to exercise its Right of First Refusal to acquire, license, and/or commercialize such ROFR Product on the same economic terms as offered by such Third Party, then, for
example, KemPharm, its Affiliates, third party licensee or purchaser may commercialize such ROFR Product. 
 2.8 Cooperation.
If Company exercises any of its rights under Sections 2.6 or 2.7, KemPharm shall, at its own cost and expense, provide Company with reasonable assistance and with access, including via an electronic data room, to all Information (e.g., Regulatory
Materials, Data and reports associated with any clinical trial) Controlled by KemPharm which is related to any Additional Product or ROFR Product and is reasonably requested by Company in connection with its evaluation of any Additional Product
Option under Section 2.6 or any Right of First Refusal under Section 2.7. 
 2.9 Confirmatory License. KemPharm
shall, if requested to do so by Company, immediately enter into a confirmatory license in the form reasonably requested by Company for purposes of recording the licenses granted under this Agreement with such patent offices or other Regulatory
Authorities as Company considers appropriate.

 ARTICLE 4 

DEVELOPMENT 
 4.1
Overview. Subject to the terms and conditions of this Agreement, the Parties will collaborate in the Development of the Initial Products in the U.S. under the direction of the JSC and in accordance with the applicable Product Development
Plan, as set forth in more detail within this Article 4. 
 4.2 Product Development Plan. The Development of each Initial
Product in the U.S. under this Agreement shall be conducted pursuant to a written development plan agreed to by the Parties (the “Product Development Plan” or “PDP”). The PDP shall contain in reasonable detail all
Development work with respect to an Initial Product required to achieve NDA approval by the FDA of such Initial Product, including anticipated timeline and detailed budget for such work. As of the Effective Date, the Parties have agreed on the
initial PDP for KP415, which is attached hereto as Exhibit B. A PDP shall be developed and reviewed by the JSC for KP484, if the Parties agree to Develop it together hereunder, based on the timing to be determined by the JSC. Each Party shall
use Commercially Reasonable Efforts to perform the 

  
 17 













 
Development activities assigned to such Party under the applicable PDP. If either Party proposes a change to a PDP, including to the scope of activities, timelines and/or budget associated
therewith, the other Party will reasonably and in good faith consider and discuss with the proposing Party the proposed change. The Parties acknowledge that a change to an existing PDP may result in delays to the completion of a particular study or
PDP, additional fees being charged to Company, or less fees being paid to KemPharm, and that any such changes, including any changes to the budgeted amount resulting therefrom, must be agreed upon by the Parties before the commencement of any
services related to the proposed changes, in which case the Parties shall update PDP. For clarity, absent such agreement by the Parties, the applicable PDP will proceed in accordance with the then-current terms, without the proposed modification(s).

 4.3 Development Responsibilities. 

(a) Subject to the oversight of the JSC and except as otherwise agreed by the Parties or as set forth in Section 4.8, KemPharm
shall be responsible for the coordination, performance, and payment of all Development work set forth on Exhibit B, including the conduct of clinical trials on behalf of Company, that is required to obtain NDA approval of the Initial Products

 4.7 Development Reports. 

(a) Each Party shall provide the JSC with written reports summarizing its Development activities under any existing PDP and the results
of such activities at each regularly scheduled JSC meeting. The Parties shall discuss the status, progress and results of each Party’s Development activities under any existing PDP at the JSC meetings. In addition, as soon as reasonably
practicable after completion of the activities under a PDP, or after takeover by Company of the activities performed by KemPharm under a PDP pursuant to Section 4.8 (if any), KemPharm will deliver to Company, at KemPharm’s cost and
expense, within [*****] days following such completion/takeover, a copy of all Information and Regulatory Materials resulting from KemPharm’s activities under the PDP that is in KemPharm’s possession. KemPharm shall use reasonable
efforts to cause the subcontractors who perform activities under the PDP on its behalf to promptly deliver to it a copy of all Information and Regulatory Materials that such subcontractors generate in the course of performing those activities. 

(b) Within [*****] days after the end of each Calendar Year during the Term of the Agreement, Company shall provide KemPharm with
a written report which summarizes, at a high level, the Development activities performed by or on behalf of Company or any of its Affiliates or Sublicensees with respect to any Product outside the United States during such Calendar Year, including
any clinical results achieved. 
 4.8 Assumption of Development Responsibilities. Without limiting any of its other rights
under this Article 4 or elsewhere in this Agreement, Company reserves the right to take over responsibility for any activities performed by KemPharm (a) under a specific PDP if Company reasonably determines that KemPharm is not able to complete
such activities within the required timeframe and that KemPharm’s inability to do so is likely to have an adverse effect on Company’s Development and/or Commercialization of the Product subject to such PDP, (b) under any and all
existing PDPs if (i) there is a Change of Control of KemPharm or (ii) in the event a Bankruptcy Event occurs or, in Company’s reasonable determination, is more likely than not to occur with respect to KemPharm. Company shall provide
written notice to KemPharm of Company’s election to assume responsibility pursuant to clause (b)(i) within [*****] days following a Change of Control of KemPharm. Company shall provide written notice to KemPharm of any determination of
the type referenced in clauses (a) or (b)(ii), including the reasons and conditions which gave rise to such determination, and KemPharm shall have [*****] days from the date of receipt to resolve such conditions to the satisfaction of
Company (the “Resolution Period”). If, after the expiration of the Resolution Period, Company determines that such reasons or conditions remain, then Company may exercise its right to take over responsibility for KemPharm’s
activities, including but not limited to the conduct of regulatory activities under Article 5 of this Agreement, under any or all existing PDPs. If Company takes over responsibility for KemPharm’s activities under any PDP(s) pursuant to this
Section 4.8, then KemPharm shall promptly (A) transfer and assign to Company in accordance with Section 4.5 any Information and Regulatory Materials resulting from its performance of the activities under the applicable PDP(s) as
contemplated in Section 4.3 above and, at Company’s request, assign to Company any Third Party sub-contract agreements entered into by KemPharm relating to those activities and (B) take all
actions that may be reasonably requested by Company for purposes of effectively teaching and transferring to Company the methods, steps, techniques and processes that Company reasonably needs to follow or know in order to practice or use effectively
any or all of the Licensed IP in the performance of such activities. All out-of-pocket costs and expenses incurred by KemPharm in connection with the transfer of the
activities under any PDP(s) to Company hereunder shall be borne by KemPharm. For the avoidance of doubt, no reimbursable Development Costs under Section 4.4 shall accrue following the completion of the takeover by Company. For the avoidance of
doubt, ownership of any Patents, Information or Inventions developed or conceived by Company in the performance of any activities conducted following a takeover hereunder shall be determined according to Section 9.1. 

  
 20 













 4.9 Subcontracts. 

(a) Other than to a subcontractor that is listed in Exhibit E attached hereto as of the Effective Date (each a Pre-Approved CRO), KemPharm shall not subcontract to Third Parties portions of any activities to be performed by it under any PDP or contract with consultants to provide services specifically relating to such
activities without the prior written consent of Company, which consent shall not be unreasonably withheld. In any event, each subcontractor shall enter into an agreement with KemPharm requiring such subcontractor (i) to maintain all
Confidential Information in confidence and (ii) to comply in all material respects with all requirements of applicable Laws, together with all applicable GLP, GMP and GCP. KemPharm shall negotiate and execute such agreements, as applicable, at
its expense, and shall supervise and be responsible under this Agreement for such subcontracted work. All such subcontracts shall be consistent with the terms of this Agreement. When entering into agreements with Third Party subcontractors
after the Effective Date pertaining to the performance of activities contemplated in any PDP, KemPharm shall use reasonable efforts to obtain the right to assign such agreements to Company or its Affiliates without the prior consent of the Third
Party subcontractor. Any subcontract, granted or entered into by KemPharm, as contemplated by this Section 4.9(a), of the exercise or performance of all or any portion of the rights or obligations that KemPharm may have under this Agreement
shall not relieve KemPharm from any of its obligations under this Agreement, except to the extent that such obligations are performed by such subcontractor in a manner consistent with KemPharm’s obligations under this Agreement. KemPharm shall
be responsible for the acts and omissions of its subcontractors in connection with their performance of any of KemPharm’s obligations or exercise of any of KemPharm’s rights hereunder and any material breach by a subcontractor may be
imputed to KemPharm. 
 (b) Company may exercise any of its rights or perform any of its obligations under this Agreement (including
any of the rights granted in Section 2.1) by subcontracting the exercise or performance of all or any portion of such rights and obligations on Company’s behalf. Any subcontract granted or entered into by Company as contemplated by this
Section 4.9(b) of the exercise or performance of all or any portion of the rights or obligations that Company may have under this Agreement shall not relieve Company from any of its obligations under this Agreement.

	 Approval Milestone Event
	  	 Milestone Payment

	 1)  FDA acceptance of NDA submission for KP415
	  	[*****]
		
	 2)  Regulatory Approval of KP415 in the U.S. [*****]
	  	[*****]
		
	 3)  Regulatory Approval of a KP415 in the U.S., with a label approved by the FDA that
includes 30-minute onset and 13-hour duration (the “30/13 Label”):
	  	
		
	 a.   If Regulatory Approval with the 30/13 Label is received [*****];
or
	  	[*****]
		
	 b.  If Regulatory Approval with the 30/13 Label is not achieved [*****], but the
30/13 Label is included in a subsequent Regulatory Approval for KP415 received by [*****]
  
	  	[*****]
	 4)  Regulatory Approval for KP484 by the FDA
	  	[*****]

 With respect to each approval milestone event in numbers 1 through 4 above, the milestone payments to be made
under this Agreement shall be due and payable only once upon the first achievement of the applicable milestone, regardless of the number of Products Developed or Commercialized, and regardless of the number of indications pursued or approved, or
whether a Product is discontinued after a milestone payment has been made. 
 8.4 Sales Milestone Payments. Company shall
notify KemPharm upon the achievement of the sales milestone events set forth below with respect to the Net Sales of any Initial Product in the U.S. in a given Calendar Year in the quarterly report referred to in Section


  
 26 













 
8.5(e). As further partial consideration for KemPharm’s grant of the rights and licenses to Company hereunder, Company shall pay to KemPharm the corresponding
one-time, non-refundable and non-creditable sales milestone payments set forth below upon delivery of such quarterly report
referred to in Section 8.5(e) after achieving the applicable milestone: 
  

			
	 Sales Milestone Event
	  	 Milestone Payment

	 1)  Year total annual U.S. Net Sales of any Initial Product first exceed
[*****], payable only if KP415’s first Regulatory Approval does not include the 30/13 Label.
	  	 [*****]

		
	 2)  Year total annual U.S. Net Sales of any Initial Product first exceeds
[*****]
	  	 [*****]

		
	 3)  Year total annual U.S. Net Sales of any Initial Product first exceeds
[*****]
	  	 [*****]

		
	 4)  Year total annual U.S. Net Sales of any Initial Product first exceeds
[*****]
	  	 [*****]

		
	 5)  Year total annual U.S. Net Sales of any Initial Product first exceeds
[*****]
	  	 [*****]


 Net Sales of all Initial Products in the U.S. shall not include [*****]. In addition, [*****] shall not count
towards the calculation of the annual U.S. Net Sales thresholds above. 
 For the avoidance of doubt, each aforementioned sales milestone event payments
shall be made only once, the first time the milestone event is achieved, regardless of the number of Initial Products achieving the commercial event milestones, or the number of Calendar Years in which any Initial Product achieves such commercial
event milestone. For example, if for a Calendar Year, aggregate annual worldwide Net Sales for KP415 are [*****], the total sales milestone payment earned shall be [*****], and such sales milestone payment shall no longer be triggered
by any Initial Product in any Calendar Year. Furthermore, the total maximum milestones payable under this Section 8.4 shall not exceed four hundred and twenty million U.S. Dollars (US$420,000,000). 

  
 27 













 8.5 Royalty. 

(a) U.S. Royalty Rate. Following the First Commercial Sale of any Initial Product in the Field in the U.S. and as further
consideration for KemPharm’s grant of the rights and licenses to Company hereunder, Company shall pay to KemPharm a tiered royalty (“Royalty”) on the Net Sales of such Initial Product in the U.S. as calculated by multiplying
the applicable royalty rate set forth below by the corresponding incremental aggregate annual Net Sales: 
  

			
	 Aggregate annual Net Sales of each Initial Product sold in the
U.S.
	  	 Royalty Rate

	 1)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
less than or equal to [*****]
	  	 [*****]

		
	 2)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
greater than [*****] and less than or equal to [*****]
	  	 [*****]

		
	 3)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
greater than [*****] and less than or equal to [*****]
	  	 [*****]

		
	 4)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
greater than [*****] and less than or equal to [*****]
	  	 [*****]

		
	 5)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
greater than [*****] and less than or equal to [*****]
	  	 [*****]

		
	 6)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
greater than [*****] and less than or equal to [*****]
	  	 [*****]

		
	 7)  For that portion of aggregate annual Net Sales in the U.S. per Calendar Year
greater than [*****]
	  	 [*****]


 Net Sales of any Initial Product in the U.S. shall not include [*****]. In addition, in no event shall the manufacture
of an Initial Product give rise to a Royalty obligation. For clarity, Company’s obligation to pay Royalties to KemPharm under this Section 8.5(a) is imposed only once with respect to the same unit of Initial Product regardless of the
number of Licensed Patents pertaining thereto. 
 By way of illustration, assume in a Calendar Year, during the Royalty Term, that (i) aggregate annual
Net Sales of KP415 in the U.S. total [*****] and (ii) no adjustments or deductions to payments under this Article 8 apply. Then the total Royalties due and payable by Company to KemPharm for such Net Sales would be [*****],
calculated as follows: 
 [*****] 

[*****] 
 [*****] 

[*****] 

  
 28 













 (b) Ex-U.S. Payments. Following the
First Commercial Sale of any Initial Product in the Field in any country outside of the U.S. and as further consideration for KemPharm’s grant of the rights and licenses to Company hereunder, Company shall pay to KemPharm the following: 

(i) If Company or its Affiliates directly Commercialize such Initial Product in any country outside of the U.S., Company shall pay to
KemPharm a Royalty on the Net Sales of such Initial Product in each applicable country outside of the U.S., as calculated by multiplying such Royalty rate by the corresponding aggregate annual Net Sales in each such country: 

 

			
	 Aggregate annual Net Sales of an Initial Product sold outside the
U.S.
	  	 Royalty Rate

	 1)  For that portion of aggregate annual Net Sales in each country per Calendar
Year less than or equal to [*****]
	  	 [*****]

		
	 2)  For that portion of aggregate annual Net Sales in each country per Calendar
Year greater than [*****]
	  	 [*****]


 Net Sales of any Initial Product outside the U.S. shall not include [*****]. In addition, in no event shall the
manufacture of an Initial Product give rise to a Royalty obligation. For clarity, Company’s obligation to pay Royalties to KemPharm under this Section 8.5(b) is imposed only once with respect to the same unit of Initial Product regardless
of the number of Licensed Patents pertaining thereto. 
 (ii) If Company or its Affiliates enters into a sublicense to Commercialize
such Initial Product in any country outside of the U.S., Company shall pay a one-time value share payment to KemPharm equal to [*****]. For clarity, Company shall not be obligated to make any payment to
KemPharm under this Section 8.5(b)(ii) with respect to any other compensation or consideration received by Company in connection with (but after the execution of) such sublicense agreement, including any value received in the form of royalty
payments. 
 (c) Royalty Term. Company’s obligation to pay royalties pursuant to this Section 8.5 shall continue, on
an Initial Product-by-Initial Product and country-by-country basis, until the earlier of:
(i) the expiration of the last-to-expire Valid Claim in the Licensed Patents in such country that claims the sale or use of such Initial Product in such country;
and (ii) [*****] years from the date of the commercial launch of any Generic Product of such Initial Product in such country, provided that if the applicable Generic Product of such Initial Product has been removed from the market in
such country due to a successful enforcement action by either Party in such [*****] year period, then the Royalty term shall not expire pursuant to this clause (ii) for such applicable Generic Product of such Initial Product that has
been removed from the market (although it may expire for other Generic Products of such Initial Product that are not removed) (the “Royalty Term”). 

  
 29 













 (d) Royalty Payment Reduction. 

(i) If the first Regulatory Approval for the first approved label of KP415 by the FDA does not include the 30/13 Label, the Royalty set
forth in Section 8.5(a) shall be reduced by [*****] with respect to all sales of KP415 in the U.S., except as set forth in the next sentence. If, subsequent to the first Regulatory Approval of KP415 in the U.S., the previously approved
label for KP415 is adjusted to include the 30/13 Label, and such adjustment is resubmitted to the FDA and the 30/13 Label is subsequently approved by the FDA, the Royalty rates applicable to the sale of KP415 in the U.S. shall be increased to
[*****] of the Royalty rates set forth in Section 8.5(a) from and after the date of such adjusted label’s approval by the FDA and during the remainder of the Royalty Term. 

(ii) On an Initial Product-by-Initial Product and country-by-country basis, after the launch of the first Generic Product of such Initial Product in such country, the Royalty set forth in Section 8.5(a) or
Section 8.5(b), as applicable, shall be reduced (after giving effect to all other applicable reductions set forth herein) by [*****] after the launch of any Generic Product of such Initial Product, provided that if the applicable Generic
Product of such Initial Product has been removed from the market in the U.S. as a result of a successful enforcement action by either Party in the first [*****] years from the date of its commercial launch, then the royalty rate shall no
longer be reduced as provided in this Section 8.5(d)(ii); provided further that if other Generic Products of such Initial Product are on the market (or enter the market), then the Royalty shall continue to be reduced (or shall be reduced) by
[*****] until such time as such other Generic Products of such Initial Product, if any, are not on the market as a result of a successful enforcement action by either Party from the date of their respective commercial launch. 

(iii) In the event that Company or any of its Affiliates or Sublicensees is required to pay royalties, damages or other amounts to any
Third Party in order to obtain or as consideration for a license under any Patent or other intellectual property owned or controlled by such Third Party which is necessary for the Commercialization of an Initial Product in any country in the
Territory, Company shall have the right to deduct, from the payments that would otherwise have been due pursuant to this Agreement (after giving effect to all other applicable reductions set forth herein), an amount equal to the payment made by
Company, or its Affiliates or Sublicensee to such Third Party pursuant to such license on account of the sale of such Initial Product in such country during such calendar quarter, provided that the reduction taken under this Section 8.5(d)(iii)
shall not exceed [*****] of the Royalty otherwise due for any calendar quarter on Net Sales for the applicable Initial Product, and provided that any excess amounts remaining to be deducted may be deducted from each subsequent sequential
quarter until fully recouped by Company. 
 (iv) In the event that KemPharm or Company receives a request for a Compulsory License
anywhere in the world, it shall promptly notify the other Party. If any Third Party obtains a Compulsory License, then KemPharm or Company (whoever has first notice) shall promptly notify the other Party. Thereafter, as of the date the Third Party
obtained such Compulsory License, the Royalty rate payable under Section 8.5 to KemPharm for Net Sales will be adjusted (after giving effect to all other applicable reductions set forth herein) to equal any lower royalty rate granted to such
Third Party for such country with respect to the sales of such 

  
 30 













 
Initial Product therein. In addition, should Company grant a sublicense to a Third Party in the U.S. to avoid the imposition of such a Compulsory License, the Royalty rate payable under
Section 8.5 to KemPharm for Net Sales in such country shall also be adjusted to match any lower royalty rate payable by such Sublicensee for such country under such sublicense. 

(v) The reductions and deductions set forth in this Section 8.5(d) are cumulative and shall apply, in each case, to the maximum
extent applicable. 
 (e) Royalty Reports and Payment. Following the First Commercial Sale of any Initial Product in the
Territory, within [*****] days after the end of each of the first three (3) calendar quarters in a Calendar Year and [*****] days after the end of the last calendar quarter of a Calendar Year, Company shall submit to KemPharm a
report setting forth, on an Initial Product-by-Initial Product and country-by-country
basis: (i) the amount of gross sales of each Initial Product sold in such calendar quarter; (ii) a calculation of Net Sales showing the deductions from gross sales (by major category as set forth in the definition of Net Sales) to
determine Net Sales; (iii) a calculation of the Royalty payment due to KemPharm for such calendar quarter, including any deductions taken under Section 8.5(d); (iv) the aggregate annual Net Sales of such Initial Products and whether any
sales milestone has been achieved; and (v) the exchange rates used in the forgoing calculation, if any. Concurrent with the delivery of the quarterly Royalty report, Company shall pay to KemPharm all Royalties owed for such calendar quarter.

 8.6 Payment Method. All payments due under this Agreement shall be made by wire transfer U.S. Dollars in immediately
available funds to a bank and account designated in writing by the receiving Party. 
 8.7 KemPharm Consultation Fees.
As provided in Articles 4, 6 and 7 and subject to the overall cap on reimbursements to KemPharm in Section 4.4, as applicable, Company shall pay to KemPharm a consultation fee, billed hourly per employee, for services and/or activities related
to Development, regulatory or manufacturing activities for the Products (a) expressly contemplated in a PDP or otherwise requested in writing by Company and (b) provided or managed by employees of KemPharm (“Consultation
Fee”). Initially, the Consultation Fee shall be [*****] per hour and will increase by [*****] on each anniversary of the Effective Date of this Agreement. 

8.8 Records; Audits. 

(a) Company shall and shall ensure that its Affiliates and its and their respective Sublicensees, maintain complete and accurate records
in sufficient detail to permit KemPharm to confirm the accuracy of the calculation of Royalty payment (including Net Sales) and the achievement of the sales milestone events. All payments and other amounts under this Agreement shall be accounted for
in accordance with U.S. GAAP. Upon reasonable prior notice, such records shall be available for examination during regular business hours for a period of [*****] years from the end of the Calendar Year to which they pertain, and not more
often than [*****] each Calendar Year, by an independent certified public accountant selected by KemPharm and reasonably acceptable to Company, for the sole purpose of verifying the accuracy of the financial reports furnished by Company
pursuant to this Agreement and any 

  
 31 













 
payments with respect thereto. Any amounts shown to be owed but unpaid shall be paid within [*****] days from the accountant’s report. Any overpayment based on the
computations set forth in Section 8.5, shall become a credit for future amounts owed by Company to KemPharm. KemPharm shall bear the full cost of such audit unless such audit discloses an underpayment by Company of more than
[*****] of the amount due for the audited period, in which case Company shall bear the full cost of such audit. 

(b) KemPharm shall, and shall ensure that its Affiliates, maintain complete and accurate records in sufficient detail to permit Company
to confirm the accuracy of the calculation of the Development cost reimbursed under this Agreement. All such cost shall be accounted for in accordance with U.S. GAAP. Upon reasonable prior notice, such records shall be available for examination
during regular business hours for a period of [*****] years from the end of the Calendar Year to which they pertain, and not more often than [*****] each Calendar Year, by an independent certified public accountant selected by Company
and reasonably acceptable to KemPharm, for the sole purpose of verifying the accuracy of the financial reports furnished by KemPharm pursuant to this Agreement and any payments with respect thereto. Any such auditor shall not disclose
KemPharm’s Confidential Information, except to the extent such disclosure is necessary to verify the accuracy of the financial reports submitted by KemPharm and/or the amount of payments due with respect thereto. Any overage or underpayment to
Company shall be refunded or paid, if applicable, within [*****] days from the accountant’s report, as calculated from the original date such overage was applied or underpayment was due. Any overpayment based on the computations set
forth in Section 8.5 shall become a credit for future amounts owed by KemPharm. Company shall bear the full cost of such audit unless such audit discloses an overage or underpayment by KemPharm of more than [*****] of the amount of due
for the audited period, in which case KemPharm shall bear the full cost of such audit. 
 (c) If a Party disputes an auditor’s
report, the dispute shall be subject to the dispute resolution process set forth in Article 14. 
 (d) Each Party shall treat all
information that it receives under this Section 8.8 in accordance with the confidentiality provisions of Article 12 of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the other
Party obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement, except to the extent necessary for such Party to enforce its rights under this Agreement. 

8.9 Taxes. 

(a) Taxes on Income. Except as otherwise provided in this Section 8.9, each Party shall be solely responsible for the
payment of all taxes imposed on its share of income arising directly or indirectly from the efforts of the Parties under this Agreement. 

(b) Tax Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to reduce or eliminate Tax
Withholding or similar obligations in respect of the milestone payment, Royalty payment, and other payments made under this Agreement. To the extent a Party is required to deduct and withhold taxes from any payment to the other Party,


  
 32 













 
the paying Party shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to the receiving Party an official tax certificate or other
evidence of such withholding sufficient to enable the receiving Party to demonstrate such payment of taxes to any applicable Governmental Authority. The receiving Party shall provide the paying Party any tax forms that may be reasonably necessary in
order for the paying Party not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by applicable
Laws, of withholding taxes or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax. 

(c) Withholding Taxes. If a Party is required by applicable Laws to make any tax deduction, tax withholding or similar payment
from any amount paid or payable by such Party to the other Party (a “Tax Withholding”) under this Agreement, then such amounts shall be deducted from the amount otherwise required to be paid. 

(d) VAT. All payments due pursuant to this Agreement shall be offset by any value-added tax (“VAT”) (which, if
applicable, shall be payable by the paying Party upon receipt of a valid VAT invoice). If the receiving Party determines that it is required to report any such tax, the paying Party shall promptly provide the receiving Party with applicable receipts
and other documentation necessary or appropriate for such report. For clarity, this Section 8.9(d) is not intended to limit Company’s right to deduct VAT in determining Net Sales. 

ARTICLE 9 
 INTELLECTUAL
PROPERTY MATTERS 
 9.1 Inventions. 

(a) Ownership. Inventorship of any Inventions will be determined in accordance with the standards of inventorship and conception
under U.S. patent laws, and ownership of Inventions shall follow inventorship. Each Party shall solely own any Inventions made solely by its and its Affiliates’ employees, agents, or independent contractors. The Parties shall jointly own any
Joint IP. Except to the extent KemPharm is restricted by the licenses granted to Company under this Agreement, each Party shall be entitled to practice, license, assign and otherwise exploit the Joint IP without the duty of accounting or seeking
consent from the other Party. Each Party shall require all of its employees, and use its best efforts to require its contractors and agents, and any Affiliates and Third Parties working on its behalf under this Agreement (and their respective
employees, contractors and agents), to execute such documents and to take such other actions as are necessary to assign, transfer or otherwise convey to such Party any Inventions made by any of them on behalf of such Party as is sufficient for
Company or KemPharm to meet their obligation to the other Party under this Agreement. 
 (b) Disclosure. Each Party shall
promptly disclose to the other Party all Inventions, including all invention disclosures or other similar documents submitted to such Party by its, or its Affiliates’, employees, agents or independent contractors relating to such Inventions,

 9.2 Patent Prosecution.  

(a) Prosecution by the Parties. KemPharm shall have the first right, at its own cost and expense, to prepare, file,
prosecute and maintain the Licensed Patents through Patent grant and Company shall have the first right to prepare, file, prosecute and maintain the Joint Patents as well as maintain and prosecute the Licensed Patents subsequent to Patent grant
during the Term of this Agreement, [*****], on a worldwide basis. For the purpose of this Article 9, “prosecution” shall include any post-grant proceeding in the Territory, including opposition proceedings. KemPharm
shall provide Company reasonable opportunity to review and comment, as well as participate in internal and external meetings, on such prosecution efforts regarding the Licensed Patents as follows: KemPharm shall promptly provide Company with copies

Joint Patents in any country in the Territory. Company shall provide such notice reasonably in advance of any filing or payment due date, but in any event prior to any due date that requires action in order to avoid loss of rights, in connection

any, shall be listed for inclusion in the Approved Drug Products with Therapeutic Equivalence Evaluations pursuant to 21 U.S.C. Section 355, or any successor Law in the U.S., together with any comparable Laws in any other country in the
Territory. Should the Parties disagree, [*****] shall have the final decision. 
 9.3 Patent Enforcement. 

(a) Notification. If either Party becomes aware of any existing or threatened infringement of any Licensed IP or Joint IP, or if
a Third Party claims that any Licensed Patent or Joint Patent is invalid or unenforceable, it shall promptly notify the other Party in writing to that effect. In addition, each Party shall immediately give written notice to the other Party of any
certification of which they become aware filed pursuant to 21 U.S.C. Section 355(b)(2)(A) (or any amendment or successor statute thereto) claiming that any Licensed Patents or Joint Patents covering any Compound or Product, or the manufacture
or use of either of the foregoing, are invalid or unenforceable, or that infringement will not arise from the manufacture, use or sale of a product by a Third Party. 

(b) Enforcement Rights. 

(i) As between the Parties, Company shall have the first right, but not the obligation, to resolve any infringement or claim by a Third
Party of the type referenced in Section 9.3(a), including the right to bring an appropriate suit, defend against any such claim, or take other action to enforce or defend the applicable Licensed Patent or Joint Patent against any such Third
Party, including as a defense or counterclaim in connection with any Infringement Action, and to compromise or settle any such infringement or claim, [*****]. If Company does not commence a suit or take such other action as Company reasonably
determines is necessary or appropriate to enforce or defend the applicable Licensed Patents or Joint Patents against such Third Party infringement or claim (which may include sending a cease and desist letter) within [*****] days of first
becoming aware of such infringement or claim, then, subject to Company’s prior consent (not to be unreasonably withheld, conditioned, or delayed), KemPharm shall have the right but not the obligation to commence such a suit or take such other
action in regards to the applicable Licensed Patents or Joint Patents against such Third Party infringement or claim, at KemPharm’s own cost and expense. 

(ii) Delegation of Enforcement Rights. Company shall have the right, in its sole discretion, to delegate its rights under
Section 9.3(b), in whole or in part, to any of its Affiliates or one or more Sublicensees, provided that any such Affiliate or Sublicensee shall comply with the terms of this Section 9.3. 

  
 35 













 (c) Collaboration. 

(i) Each Party shall provide to the Party bringing a claim, suit or action under Section 9.3(b) (the “Enforcing
Party”) with reasonable assistance in such enforcement or defense, at such Enforcing Party’s request and expense, including joining such action as a party plaintiff if required by applicable Laws to pursue such action. The Enforcing
Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts and shall reasonably consider the other Party’s comments on any such efforts. The non-enforcing
Party shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense. The Enforcing Party shall not settle any such suit or action in any manner that admits that any Licensed Patent or Joint Patent is
invalid or unenforceable without the other Party’s prior written consent and, in the case of KemPharm, KemPharm may not settle or otherwise compromise any suit or action in a way that adversely affects or would be reasonably expected to
adversely affect Company’s rights or benefits hereunder, without Company’s prior written consent, and in the case of Company, Company may not settle or otherwise compromise any suit or action in a way that adversely affects, or would be
reasonably expected to affect, KemPharm’s rights or benefits hereunder, without KemPharm’s express written consent. The foregoing shall not limit Company’s rights under Section 8.5(d)(iii). 

(ii) Each Party shall share with the other Party all Information available to it regarding such alleged infringement or claim to the
Licensed IP or Joint IP by a Third Party, pursuant to a mutually agreeable “common interest agreement” executed by the Parties under which the Parties agree to their shared, mutual interest in the outcome of any suit to enforce the
Licensed Patents or Joint Patents against such Third Party; provided, however, that no Party shall be required to disclose Information to the other Party to the extent such disclosure would cause the loss of attorney/client privilege or would be
considered confidential information not subject to the terms of this Agreement. 
 (d) Expenses and Recoveries. The Enforcing
Party shall be solely responsible for any expenses it incurs as a result of such enforcement action. If the Enforcing Party recovers monetary damages in such claim, suit or action brought under Section 9.3(b), such recovery shall be allocated
[*****]; provided, however, that if [*****] is the Enforcing Party, then such remaining amounts shall be [*****]. 

(e) Other Infringements. Company shall have the sole right and authority, but not the obligation, to enforce Company Patents
against any Third Party infringement and to defend against any claim that any Company Patent is invalid or unenforceable, including as a defense or counterclaim in connection with any Infringement Action, at its own cost and expense, and Company
shall be entitled to retain all recoveries resulting from all such enforcement actions. KemPharm shall provide reasonable assistance to Company with respect thereto, including providing access to relevant documents and other evidence and making its
employees available, subject to Company’s reimbursement of any reasonable out-of-pocket expenses incurred by KemPharm on an
on-going basis in providing such assistance.

 9.4 Third Party Infringement Claims. If the manufacture, sale or use of the
Products in the Field in the Territory pursuant to this Agreement results in a claim, suit or proceeding alleging Patent infringement against KemPharm or Company, or their respective Affiliates, licensees or Sublicensees (each, an
“Infringement Action”), such Party shall promptly notify the other Party hereto in writing. Company shall have the right, [*****], but not the obligation, to defend any Infringement Action and to compromise or
settle such Infringement Action. If Company declines or fails to assert its intention to defend such Infringement Action within [*****] days after sending (in the event that KemPharm is the notifying Party) or receipt (in the
event that Company is the notifying Party) of notice under this Section 9.4, then KemPharm shall have the right to defend such Infringement Action. The Party defending such Infringement Action shall have the sole and exclusive right to select
counsel for such Infringement Action. Each Party shall share with the other Party all Information available to it regarding such Infringement Actions, pursuant to a mutually agreeable “common defense agreement” executed by the Parties
under which the Parties agree to their shared, mutual interest in the outcome of any such Infringement Actions; provided, however, that no Party shall be required to disclose Information to the other Party to the extent such disclosure would cause
the loss of attorney/client privilege. Neither Party shall settle such Infringement Action, or make any admissions or assert any position in such Infringement Action, in a manner that would materially adversely affect the rights or interests of the
other Party hereunder, without the prior written consent of the other Party, which shall not be unreasonably withheld or delayed. For clarity, the foregoing sentence shall not serve to limit or condition Company’s exercise of its rights under
Section 8.5(d)(iii). Subject to the respective indemnity obligations of the Parties set forth in Article 11, the Party controlling the defense of the Infringement Action shall pay all costs associated with such Infringement Action other than
the expenses of the other Party if the other Party elects to join such Infringement Action (as provided in the last sentence of this Section 9.4); provided, that, without limitation of KemPharm’s indemnification obligations under Article
11, [*****]. Each Party shall have the right to join an Infringement Action defended by the other Party, at its own expense.

such elections, and KemPharm shall abide by all such elections.

selected by Company, which may be a KemPharm Product Mark.

Company’s cost and expense, the applicable Product trademark. 
 (b) Company Housemarks. In addition, Company shall have
the right to brand the Products in the Field in the Territory with those trademarks of Company that are associated with Company’s name or identity (“Company Housemarks”); provided, however, that Company shall not, and
shall ensure that its Affiliates and Sublicensees will not, make any use of trademarks that are confusingly similar to any trademarks or house marks of KemPharm or its Affiliates, including the corporate name of KemPharm or any of its Affiliates,
without KemPharm’s prior written consent. Company shall own all rights in the Company Housemarks, and all goodwill in the Company Housemarks shall accrue to Company.

 13.1 Term. The term of this Agreement (the “Term”) shall commence upon the Effective Date
and, unless earlier terminated pursuant to this Article 13, shall, (a) with respect to the rights and licenses granted to Company under Section 2.1(a) for the Initial Products, continue on an Initial Product-by-Initial Product and country-by-country basis until the expiration of the Royalty Term for such Initial Product in
such country and (b) with respect to the rights and licenses granted to Company under Section 2.1(a) for all other Products, continue on an exclusive, perpetual, fully paid basis. After the expiration (but not early termination) of this
Agreement for an Initial Product in a country, the licenses granted by KemPharm to Company under Section 2.1(a) shall become exclusive, fully paid, perpetual and irrevocable with respect to such Initial Product in such country. 

  
 45 













 13.2 Termination by Company. Company may terminate this Agreement, in its
entirety or on a Product-by-Product or country-by-country basis, at Company’s
convenience either (i) prior to the first Regulatory Approval of a Product upon [*****] days’ prior written notice to KemPharm, or (ii) subsequent to the first Regulatory Approval of a Product upon
[*****] days’ prior written notice to KemPharm. 
 13.3 Termination by KemPharm. KemPharm may
terminate this Agreement in its entirety immediately upon written notice to Company, if Company or its Affiliates directly or indirectly, individually or in association with any other person or entity, challenges the validity, enforceability or
scope of any Licensed Patent and such challenge is not required under a court order or subpoena and is not a defense against a claim, action or proceeding asserted by KemPharm. Additionally, KemPharm may terminate this Agreement in its entirety
immediately upon written notice to Company, if a Sublicensee of Company or its Affiliates directly or indirectly, individually or in association with any other person or entity, challenges the validity, enforceability or scope of any Licensed
Patent, and such challenge is not required under a court order or subpoena and is not a defense against a claim, action or proceeding asserted by KemPharm, and Company fails, within [*****] days of a written request by KemPharm,
to either terminate the applicable sublicense agreement with such Sublicensee or cause such Sublicensee to cease such patent challenge; provided however that KemPharm may not terminate if a court of competent jurisdiction has prevented Company from
terminating such applicable sublicense agreement through an injunction or similar mechanism provided that Company is continuing to make reasonable efforts to terminate such applicable sublicense agreement. 

13.4 Termination for Breach. 

(a) Each Party may terminate this Agreement immediately upon written notice to the other Party, if the other Party materially breaches
its obligations under this Agreement and, after receiving written notice identifying such material breach in reasonable detail, fails to cure such material breach within [*****] days from the date of such notice. For clarity, such material
obligations may apply to the performance of either: (i) this Agreement in its entirety, in which case this provision shall apply to the entire Agreement; or (ii) a specific Product or Product(s), in which case this provision shall apply
only to such affected Product or Product(s). 
 (b) Serious Material Breach. If KemPharm commits a Serious Material Breach and
such breach by KemPharm is not cured within [*****] days of receipt following a notice from Company under Section 13.4(a) (the “Cure Period”) or is unable to be cured, Company may elect not to terminate this Agreement
and, instead, during the period commencing at the end of the Cure Period or, if such breach is unable to be cured, upon KemPharm’s receipt of Company’s notice of breach under Section 13.4(a) and continuing until the end of the last
Royalty Term in all countries, (i) reduce the approval milestone payments under Section 8.3, the sales milestone payments under Section 8.4 and the then-applicable Royalty rates under Section 8.5 by [*****] and
(ii) assume full and exclusive control and responsibility for all activities being performed or to be performed by KemPharm with respect to any Product hereunder, including all Development activities being conducted by KemPharm under any PDP
and all further interactions with Regulatory Authorities with respect to any Product; provided, that such elections under this Section 13.4(b) shall not be Company’s sole remedy with respect to the Serious Material Breach by KemPharm. 


  
 46 













 (c) Material Breach Dispute. Any dispute regarding an alleged material breach
of this Agreement shall be resolved in accordance with Article 14 hereof. 
 13.5 Termination Due to Bankruptcy. 

(a) A Party may terminate this Agreement in its entirety immediately upon written notice to the other Party, if the other Party files in
any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of such other Party
or of its assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not
dismissed within [*****] days after the filing thereof, or if the other Party proposes or becomes a party to any dissolution or liquidation, or if the other Party makes an assignment for the benefit of its creditors (each of the foregoing, a
“Bankruptcy Event”). 
 (b) If this Agreement is terminated due to the rejection of this Agreement by or on behalf of
a Party (the “Bankrupt Party”) under Section 365 of the United States Bankruptcy Code (the “Code”) or an equivalent type of provision under a relevant Law applicable to the Bankrupt Party, all licenses and
rights to licenses granted under or pursuant to this Agreement by the Bankrupt Party to the other Party (the “Non-Bankrupt Party”) are, and shall otherwise be deemed to be, for purposes of
Section 365(n) of the Code, licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code. The Parties agree that the Non-Bankrupt Party, as a licensee of such
rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Code, and that upon commencement of a bankruptcy proceeding by or against the Bankrupt Party under the Code, the Non-Bankrupt Party shall be entitled to a complete duplicate of, or complete access to (as the Non-Bankrupt Party deems appropriate), any such intellectual property and all
embodiments of such intellectual property. Such intellectual property and all embodiments thereof shall be promptly delivered to the Non-Bankrupt Party (i) upon any such commencement of a bankruptcy
proceeding upon written request therefor by the Non-Bankrupt Party, unless the Bankrupt Party elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under
(i) above, upon the rejection of this Agreement by or on behalf of the Bankrupt Party upon written request therefor by the Non-Bankrupt Party. The foregoing provisions are without prejudice to any rights
the Non-Bankrupt Party may have arising under the Code or other applicable Law. The Parties intend for the substance of this Section 13.5(b) to apply worldwide, even if the Code does not expressly apply
to the Bankrupt Party or to the Non-Bankrupt Party. 
 (c) Right of First Refusal. In
addition to the foregoing, in the event of a Bankruptcy Event involving KemPharm, Company shall, to the extent allowed by Law, have a Right of First Refusal to purchase all of KemPharm’s interest in the Product and the Licensed IP (the
“Additional Right of First Refusal”). The Additional Right of First Refusal shall operate as follows: 

  
 47 













 (i) KemPharm (or other authorized representative of KemPharm, including a bankruptcy
trustee) shall promptly send to Company a reasonably detailed written notification of any Bankruptcy Event. 
 (ii) KemPharm (or
other authorized representative of KemPharm, including a bankruptcy trustee) shall promptly send to Company a written notification of any Third Party offer made on the Compound, Product or Licensed IP. For a period of up to [*****] days after
Company receives such notice (such period, the “Additional Right of First Refusal Notice Period”), it shall notify KemPharm of its intention to exercise its Additional Right of First Refusal. In the event Company exercises its
Additional Right of First Refusal, the terms of the Third Party offer shall become binding upon Company and KemPharm. For the avoidance of doubt, KemPharm shall not enter into any agreement with a Third Party relating to KemPharm’s interest in
the Products or Licensed IP during the Additional Right of First Refusal Notice Period. 
 13.6 Effect of Termination. Upon any
early termination of this Agreement (but not expiration), the following shall apply, in addition to any other rights and obligations under this Agreement, with respect to such Product(s) and country(ies) as are the subject of such termination: 

(a) Licenses. All licenses and other rights granted by KemPharm to Company under this Agreement shall terminate. At
KemPharm’s request, if this Agreement is terminated by Company pursuant to Sections 13.2, Company shall negotiate in good faith a grant by Company or its Affiliates to KemPharm of a milestone (including an
up-front payment) and royalty-bearing license in the Field under any Company IP necessary to make, have made, import, use, offer to sell and sell such Product(s). Such license shall contain such customary
representations, warranties, covenants and agreements satisfactory in form and substance to the Parties and their legal advisors as are necessary or appropriate for transactions of this type. For the avoidance of doubt, such obligation to negotiate
in good faith does not impose on either Party an obligation to enter into an agreement for the grant of such a license if the Parties cannot agree through such good faith negotiations on the terms and conditions of such license. 

(b) Regulatory Materials; Data. If this Agreement is terminated by KemPharm pursuant to Section 13.3, 13.4, or 13.5, Company
shall transfer and assign to KemPharm or its designee all Regulatory Materials, including Regulatory Approvals, prepared or obtained by or on behalf of Company prior to the date of such termination to the extent solely related to such Product(s) and
country(ies) and to the extent such transfer and assignment is possible under applicable Law in the Territory. Company shall also promptly transfer and/or assign to KemPharm all Data, including pharmacovigilance data, generated under this Agreement
(whether generated by or on behalf of KemPharm or Company), in Company’s Control as of the effective date of termination to the extent solely related to such Product(s) and country(ies). Company shall have the right to retain one copy of such
transferred Regulatory Materials and Data for record-keeping purposes. In addition, each Party shall promptly return or destroy, at the other Party’s election, all Confidential Information of such Party. 

  
 48 













 (c) Transition Assistance. Except to the extent this Agreement is terminated
by Company pursuant to Section 13.2, 13.4 or 13.5 and to the extent not prohibited by Law, Company shall wind down any ongoing clinical trials with respect to such Product(s) or, at KemPharm’s option and upon KemPharm’s request,
provide such assistance as may be reasonably necessary for KemPharm to assume responsibility for the conduct of such clinical trials. Additionally, Company shall provide KemPharm with copies of any promotional and marketing materials generated by or
on behalf of Company with respect to the Products prior to the effective date of early termination, except to the extent this Agreement is terminated by Company pursuant to Section 13.2, 13.4 or 13.5. 

(d) Cost. If this Agreement is terminated by KemPharm pursuant to Section [*****], Company shall bear its own costs
incurred under Sections [*****]; otherwise KemPharm shall reimburse Company for all such costs. 
 (e) Inventory.
KemPharm shall have the right, but not the obligation to purchase any and all of the inventory of the Products, including any samples and/or ingredients, held by Company or its Affiliates or Sublicensees as of the date of termination, at a price
equal to [*****]. 
 (f) Partial Termination. For the avoidance of doubt, if this Agreement is terminated with respect
to only one or more Product(s) or country(ies), then this Section 13.7 shall apply only to such terminated Product(s) or country(ies). 

(g) Survival of Sublicenses. Upon any termination of this Agreement, each of Company’s Sublicensees shall continue to have
the rights and license set forth in its sublicense agreements, which agreements shall be automatically assigned to KemPharm; provided, however, that such Sublicensee is not then in breach of any of its material obligations under its sublicense
agreement. 
 (h) Diligence Obligations. Immediately following Company’s notification of termination to KemPharm pursuant
to Sections 13.2 or 13.4(a), the diligence obligations in Section 4.2 and Section 6.4 shall no longer apply and Company shall have the right to wind-down all then on-going Development, manufacturing
and/or Commercialization activities. 
 13.7 Survival. Termination or expiration of this Agreement shall not affect rights or
obligations of the Parties under this Agreement that have accrued prior to the date of termination or expiration. Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement:
Articles 1, 8 (only with respect to any payment obligations that accrued prior to the date of termination or expiration), 11, 12 (for the period of time referenced in Section 12.1), 14, and 15, and Sections 9.1, 10.5, 13.6, 13.7 and 13.8. 

13.8 Accrued Liabilities; Termination Not Sole Remedy. Expiration or termination of this Agreement shall not relieve the Parties
of any liability that accrued hereunder prior to the effective date of such termination. In addition, termination is not the sole remedy under this Agreement and, whether or not termination is affected and notwithstanding anything contained in this
Agreement to the contrary, all other remedies under this Agreement or at Law or in equity shall remain available, except as agreed to otherwise herein. 

  
 49 













 ARTICLE 14 

DISPUTE RESOLUTION 

14.1 Disputes; Internal Resolution. The Parties recognize that disputes as to certain matters may from time to time arise that
relate to either Party’s rights and/or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation. To
accomplish this objective, the Parties agree that, if a dispute arises under this Agreement with respect to which a Party does not have final decision-making authority pursuant to Section 3.5, and the Parties are unable to resolve such dispute
within [*****] days after such dispute is first identified by either Party in writing to the other, the Parties shall refer such dispute to the Executive Officers for attempted resolution by good faith negotiations within
[*****] days after such notice is received, which shall include at least one (1) in person meeting of the Executive Officers within [*****] days after such notice is received. If the dispute is not
resolved within such [*****] days, either Party may resolve such dispute in accordance with Section 14.2. 

14.2 Governing Law. Resolution of all disputes and any remedies relating thereto, shall be governed by and construed under the
laws of the State of Delaware, U.S., without giving effect to any choice of law principles that would require the application of the laws of a different state. Each of the Parties hereby irrevocably and unconditionally consents to submit to the
exclusive jurisdiction of the courts of the State of Delaware for any matter arising out of or relating to this Agreement and the transactions contemplated hereby and agrees not to commence any litigation relating thereto except in such courts. Each
of the Parties hereby irrevocably and unconditionally waives any objection to the laying of venue of any matter arising out of this Agreement or the transactions contemplated hereby in the courts of the State of Delaware and hereby further
irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such matter brought in any such court has been brought in an inconvenient forum. 

ARTICLE 15 

MISCELLANEOUS 
 15.1
Entire Agreement; Amendment. This Agreement, including the Exhibits hereto, sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between
the Parties hereto with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof, including any pre-existing confidentiality agreement between the Parties related to the subject matter of this Agreement. The foregoing shall not be interpreted as a waiver of any remedies available to either Party as a result of
any breach, prior to the Effective Date, by the other Party of its obligations under the Confidentiality Agreement. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written,
between the Parties other than as are set forth in this Agreement. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each

 15.2 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

applicable Party, which may include an act of God, war, civil commotion, terrorist act, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production

 15.4 No Strict Construction; Headings. This Agreement has been prepared
jointly by the Parties and shall not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The
headings of each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. Except where the
context otherwise requires, the use of any gender shall be applicable to all genders. 
 15.5 Assignment. 

(a) Except as set forth in this Section 15.5, neither Party may assign or transfer this Agreement or any rights or obligations
hereunder without the prior written consent of the other Party, except that either Party may make such an assignment without the other Party’s express written consent to its Affiliates or its successor in interest to all or substantially all of
its business or asset to which this Agreement relates. Notwithstanding the foregoing, Company acknowledges and consents to the collateral assignment by KemPharm of all of its rights under this Agreement to DPDF in accordance with the Facility
Agreement Documents. 
 (b) KemPharm shall not assign or transfer any Licensed IP or its interest in any Joint IP to any of its
Affiliates or any Third Party without the prior written consent of Company, except (i) to a Person to whom the rights or obligations hereunder are assigned by KemPharm in accordance with the first sentence of Section 15.5(a), or
(ii) pursuant to the Facility Agreement Documents (the security interests in the Licensed IP granted to DPDF pursuant to the Facility Agreement Documents being hereby acknowledged by Company). 

(c) Without limiting the foregoing, if KemPharm either receives a bona fide offer that its Board of Directors intends to accept, or the
Board of Directors of KemPharm decides to sell, assign, contribute, convey, grant or otherwise transfer to any Third Party (other than DPDF) or any of KemPharm’s Affiliates all or any of KemPharm’s rights to receive payment and the
corresponding royalty reports under this Agreement (each a “Payment Assignment”), then, within [*****] Business Days after KemPharm’s receipt of, or the Board of Directors’ decision with respect to, such Payment
Assignment, KemPharm shall provide Company with written notice (the “Payment Assignment Notice”) of the existence of such potential Payment Assignment. During the Exclusive Period (as defined below), Company shall have a right of
first negotiation as follows: (a) KemPharm shall negotiate in good faith with Company regarding any Payment Assignment proposal which Company elects to deliver to KemPharm during such period, and (b) KemPharm shall not enter into a binding
agreement regarding any Payment Assignment with any Third Party unless approved by Company in writing. “Exclusive Period” means the period (a) beginning on [*****] and (b) ending [*****] days after the date
that KemPharm has delivered the Payment Assignment Notice to Company. KemPharm shall not enter into any binding agreement with any Third Party regarding a Payment Assignment until after its compliance with this Section 15.5(c) for the Exclusive
Period. If KemPharm and Company do not enter into a binding agreement with respect to a Payment Assignment within the Exclusive Period, then KemPharm may pursue the Payment Assignment with any Third Party, including the Third Party that triggered
the Payment Assignment Notice, if applicable, for a period of [*****] months following the end of the Exclusive Period. Prior to executing any definitive agreement with such Third Party in regards to any Payment Assignment,


  
 52 













 
KemPharm shall provide Company with a written summary of the material terms of the offer proposed by such Third Party and Company shall have [*****] Business Days following receipt of
such written summary from KemPharm to notify KemPharm whether or not Company agrees to enter into the Payment Assignment with KemPharm on the same economic terms as offered by such Third Party (“Payment ROFR”). If Company exercises
its Payment ROFR in a timely manner, then the Parties will execute such documents, including (as necessary) an amendment to this Agreement, to memorialize the Payment Assignment. If Company fails to exercise its Payment ROFR, then KemPharm will be
free to continue to pursue the original Payment Assignment with the original Third Party that triggered the original Payment Assignment Notice for the duration of such [*****] month period. If KemPharm receives an additional Payment
Assignment from a new Third Party during the [*****] month period described above, or KemPharm does not enter into a Payment Assignment transaction with the original Third Party that triggered the Payment Assignment Notice within the
aforementioned [*****] month period and subsequently receives a bona fide offer for a Payment Assignment from a different Third Party that the KemPharm Board of Directors intends to accept, then KemPharm shall deliver an additional Payment
Assignment Notice to Company and a new Exclusive Period shall commerce upon such delivery with regard to such new Third Party. Company agrees that in connection with any Payment Assignment, unless otherwise prohibited by Law, upon written notice
from KemPharm, Company will deliver any future payments contemplated by this Agreement, together with the royalty reports contemplated by Section 8.5(e) of this Agreement, to the extent and in accordance with the directions in such written
notice. For the avoidance of doubt, (i) nothing contained in this Section 15.5(c) shall constitute any approval of, or consent to, any Payment Assignment, to the extent such Payment Assignment would be prohibited under the Facility
Agreement Documents, and (ii) the provisions of this Section 15.5(c) shall not apply to any transfer or assignment effected pursuant to the Facility Agreement Documents (or the security interests granted thereunder). 

(d) Any permitted assignee shall assume all obligations of its assignor under this Agreement. Any assignment or attempted assignment by
either Party in violation of the terms of this Section 15.5 shall be null, void and of no legal effect. 
 15.6 Change of
Control. In the event of a Change of Control of KemPharm in which a Company Competitor acquires control (as defined in Section 1.3) of KemPharm, then as from the date of such Change of Control: 

(a) Company shall cease to have any reporting obligations hereunder toward KemPharm or its successor entity, and in particular the
obligations of Company under Section 4.7(b) shall no longer apply; and 
 (b) KemPharm or its successor entity shall promptly
assign, and shall, as applicable, cause its Affiliates to promptly assign to Company, to the extent assignable, all right, title, and interest in, to and under the Licensed Patents, including the right to file, prosecute and maintain such Licensed
Patents in the Territory, and provide Company with such assistance as Company shall request to effect such assignment; provided, however, that (i) all such Licensed Patents shall continue to be deemed Licensed Patents only for the purposes of
Section 8.5 of this Agreement, and (ii) should this Agreement ever be terminated by Company pursuant to Section 13.2, subsequent to such an assignment pursuant to this Section 15.6(b), Company shall reassign,


  
 53 













 
and shall, as applicable, cause its Affiliates to reassign, to KemPharm all right, title and interest in, to and under such Licensed Patents, including the right to file, prosecute and maintain
such Licensed Patents in all the countries of the Territory, and provide KemPharm with such assistance as KemPharm shall reasonably request to effect such reassignment. 

15.7 Performance by Affiliates. Each Party may discharge any obligations and exercise any right hereunder through any of its
Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any
breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such
Party’s Affiliate. 
 15.8 Further Actions. Each Party agrees to execute, acknowledge and deliver such further
instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 

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

15.10 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or
other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period
of time. 
 15.11 Independent Contractors. Each Party shall act solely as an independent contractor, and nothing in this
Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners
between the Parties. 
 15.12 English Language. This Agreement was prepared in the English language, which language shall
govern the interpretation of, and any dispute regarding, the terms of this Agreement. 
 15.13 Interpretation. The words
“include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” All references herein to Articles, Sections, and Schedules shall be deemed references to Articles and
Sections of, and Schedules to, this Agreement unless the context shall otherwise require. Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural the singular, the use of any gender shall be
applicable to all genders and the word “or” is used in the inclusive sense (and/or). Whenever this Agreement refers to a number of days, unless otherwise specified, such number refers to calendar days. Each Party represents that it has
been represented by legal 

  
 54 













 
counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof. In interpreting and applying the terms and provisions of this Agreement, the Parties
agree that no presumption will apply against the Party which drafted such terms and provisions. Unless the context otherwise requires, countries shall include territories. 

15.14 Counterparts. This Agreement may be executed in one (1) or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument.
