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.

As further partial consideration for KemPharm’s grant of the rights and licenses to Company hereunder, Company shall pay to KemPharm the correspondingone-time,non-refundable andnon-creditable milestone payments set forth below within[*****] days after the receipt of the copy of such NDA acceptance notice or NDA approval, as applicable, from KemPharm:


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 includes30-minute onset and13-hour duration (the “30/13 Label”):

a. If Regulatory Approval with the 30/13 Label is received[*****]; or		[*****]

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.

8.4Sales 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

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 correspondingone-time,non-refundable andnon-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).

8.5Royalty.

(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:

[*****]

(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 aone-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 InitialProduct-by-Initial Product andcountry-by-country basis, until the earlier of: (i) the expiration of thelast-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”).

(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 InitialProduct-by-Initial Product andcountry-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

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 InitialProduct-by-Initial Product andcountry-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.

8.6Payment 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.

8.7KemPharm 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.

8.8Records; 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

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.

8.9Taxes.

(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,

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.

(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[*****].

The Additional Right of First Refusal shall operate as follows:

(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.

13.6Effect 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 anup-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.

(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 thenon-going Development, manufacturing and/or Commercialization activities.

13.7Survival. 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.

13.8Accrued 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.

15.4No 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.

15.5Assignment.

(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,

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.

15.6Change 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,

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.

15.7Performance 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.

15.8Further 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.

15.9Severability. 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.

15.10No 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.

15.11Independent 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.

15.12English 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.

15.13Interpretation. 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).
