given, give notice thereof (the “Demand Notice”) to all Holders; and (y) as soon as practicable, and in any event within sixty (60) days after the date such request is given by the Initiating Holders, file a Form
S-1 registration statement under the Securities Act covering all Registrable Securities that the Initiating Holders have requested to be registered and any additional Registrable Securities requested to be included in such registration by any other
Holders, as specified by notice given by each such Holder to the Company within twenty (20) days of the date the Demand Notice is given, and in each case, subject to the limitations of Subsections 2.1(c) and 2.3.

under the Securities Act covering all 

  
 9. 

 
Registrable Securities requested to be included in such registration by the Initiating Holders and any other Holders, as specified by notice given by each such Holder to the Company within twenty
(20) days of the date the Demand Notice is given, and in each case, subject to the limitations of Subsections 2.1(c) and 2.3. 

(c) The Initiating Holders shall be entitled to no more than two (2) registrations pursuant to Sections 2.1(a) and
(b) above, taken together. 
 (d) If the Company shall furnish to the Initiating Holders a certificate signed by the
Chief Executive Officer (or other authorized officer) of the Company stating that in the good faith judgment of the board of directors of the Company (the “Board of Directors”) it would be materially detrimental to the
Company and its stockholders for the registration statement requested pursuant to this Section 2.1 to be filed, because such action would (i) materially interfere with a significant acquisition, corporate reorganization, or other
similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to comply with
requirements under the Securities Act or Exchange Act, the Company’s obligations to comply with its obligations under this Section 2.1 shall be deferred for a period not to exceed ninety (90) days from the date that such notice
was given by the Company to the Initiating Holders; provided that the Company shall only be permitted one deferral pursuant to this Section 2.1(d) in any twelve-month period; and, provided, further, that the Company shall
not register any securities for its own account or the account of any other Shareholder during such 90-day period unless such registration is an Excluded Registration. 

2.2 Company Registration. If the Company proposes to register (including, for this purpose, a registration effected by the Company for
shareholders other than the Holders) any of its securities under the Securities Act in connection with the public offering of such securities solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give
each Holder notice of such registration. Upon the request of each Holder given within twenty (20) days after such notice is given by the Company, the Company shall, subject to the provisions of Subsection 2.3, cause to be registered
all of the Registrable Securities that each such Holder has requested to be included in such registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Subsection 2.2 before the
effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. The expenses (other than Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance
with Subsection 2.6. 
 2.3 Underwriting Requirements. 

(a) If, pursuant to Subsection 2.1, the Initiating Holders intend to distribute the Registrable Securities covered by its
request by means of an underwriting, it shall so advise the Company as a part of their request made pursuant to Subsection 2.1, and the Company shall include such information in the Demand Notice. The underwriter(s) for a registration
pursuant to Section 2.1 will be selected by the Company, with the consent of the Initiating Holders, which consent shall not be unreasonably withheld, delayed or conditioned. In such event, the right of any Holder to include such
Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the 

  
 10. 

 
inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall
(together with the Company as provided in Subsection 2.4(e)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting. Notwithstanding any other provision of this
Subsection 2.3, if the underwriter(s) advise(s) the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, then the Initiating Holders shall so advise all Holders of
Registrable Securities that otherwise would be underwritten pursuant hereto, and the underwriter(s) may limit the number of shares proposed to be included in such registration and underwriting as follows, subject to Section 2.10(b)
hereof: 
 (1) first, the Other Securities shall be excluded from such registration to the extent so required by such limitation
such that the number of shares to be included by such holders of Other Securities shall be determined on a pro rata basis based upon the aggregate number of Other Securities held by each such holder seeking registration; 

(2) second, to the extent further limitation is required by the underwriters, the Registrable Securities not held by the Initiating
Holders or Cowen shall be excluded from such registration to the extent so required by such limitation such that the number of shares to be included by such Holders shall be determined on a pro rata basis based upon the aggregate number of
Registrable Securities held by Holders seeking registration who are not the Initiating Holders or Cowen; 
 (3) third, to the extent
further limitation is required by the underwriter(s), the Primary Securities shall be excluded from such registration to the extent so required by such limitation; and 

(4) fourth, to the extent further limitation is required by the underwriter(s), the Registrable Securities held by the Initiating
Holders and Cowen shall be excluded from such registration to the extent required by such limitation such that the number of shares to be included by the Initiating Holders and Cowen shall be determined on a pro rata basis based upon the
aggregate number of Registrable Securities held by the each of the Initiating Holders and Cowen. 
 To facilitate the allocation of shares in accordance
with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. 

(b) In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to
Subsection 2.2, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and its
underwriter(s), and then only in such quantity as the underwriter(s) in their sole discretion determine will not jeopardize the success of the offering by the Company. The underwriter(s) for a registration initiated by the Company pursuant to
Subsection 2.2 will be selected by the Company. If the total number of securities, including Registrable Securities, requested by shareholders to be included in such offering exceeds the number of securities to be sold (other

  
 11. 

 
than by the Company) that the underwriter(s) in the underwriter(s)’ reasonable discretion determine(s) is compatible with the success of the offering, then the Company shall be required to
include in the offering only that number of such securities, including Registrable Securities, which the underwriter(s) and the Company in their sole discretion determine will not jeopardize the success of the offering. If the underwriter(s)
determine(s) that less than all of the securities requested to be registered can be included in such offering, then the underwriter(s) may limit the number of shares proposed to be included in such registration and underwriting as follows: 

(1) first, the Other Securities shall be excluded from such registration to the extent so required by such limitation such that the
number of shares to be included by such holders of Other Securities shall be determined on a pro rata basis based upon the aggregate number of Other Securities held by each such holder seeking registration; 

(2) second, to the extent further limitation is required by the underwriters, the Registrable Securities not held by the Deerfield
Investor or Cowen shall be excluded from such registration to the extent so required by such limitation such that the number of shares to be included by such Holders shall be determined on a pro rata basis based upon the aggregate number of
Registrable Securities held by Holders seeking registration (other than the Deerfield Investor and Cowen); 
 (3) third, to the
extent further limitation is required by the underwriter(s), the Registrable Securities held by the Deerfield Investor and Cowen shall be excluded from such registration to the extent required by such limitation such that the number of shares to be
included by the Deerfield Investor and Cowen shall be determined on a pro rata basis based upon the aggregate number of Registrable Securities held by each of the Deerfield Investor and Cowen; and 

(4) fourth, to the extent further limitation is required by the underwriter(s), the Primary Securities shall be excluded from such
registration to the extent so required by such limitation. 
 To facilitate the allocation of shares in accordance with the above provisions, the Company or
the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. 
 (c) For
purposes of Subsection 2.1, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Subsection 2.3(a), fewer than fifty percent (50%) of
the total number of Registrable Securities that Holders have requested to be included in such registration statement are actually included. 

2.4 Obligations of the Company. Whenever required under this Section 2 to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible: 
 (a) prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective and, upon the request of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for a 

  
 12. 

 
period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the registration statement has been completed; provided, however, that
(i) such one hundred twenty (120) day period shall be extended for a period of time equal to the period the Holder refrains, at the request of an underwriter of Common Stock (or other securities) of the Company, from selling any securities
included in such registration, (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such one hundred twenty
(120) day period shall be extended for up to 180 days, if necessary, to keep the registration statement effective until all such Registrable Securities are sold and (iii) any registration statement registering Registrable Securities
issuable (directly or indirectly) upon exercise or conversion of the Deerfield Warrants or Deerfield Convertible Notes (or upon conversion of any shares of Preferred Stock issued or issuable upon conversion thereof) should remain effective until the
earlier of (A) the six-month anniversary of the time at which all of the Deerfield Warrants have been exercised and all the principal amounts under the Deerfield Convertible Notes have been converted and (B) the six-month anniversary of
the end of the term of the Deerfield Warrants and the time on which all principal amounts under Deerfield Convertible Notes have been fully satisfied (the “Registrant Expiration Period”); 

(b) prepare and file with the SEC such amendments and supplements to such registration statement, and the prospectus used in
connection with such registration statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such registration statement; 

(c) furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus, as required by the
Securities Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities; 

(d) use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such
other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders; provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in
any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

(e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the underwriter(s) of such offering; 
 (f) use its commercially reasonable efforts to cause all such
Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then
listed; 
 (g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and
provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration; 

  
 13. 

 (h) promptly make available for inspection by the selling Holders, any underwriters
participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriters or selected by the selling Holders, all financial and other records, pertinent corporate
documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in
each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; 

(i) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has
been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and 
 (j)
after such registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or prospectus. 

In addition, the Company shall ensure that, at all times after any registration statement covering a public offering of securities of the
Company under the Securities Act shall have become effective, its insider trading policy shall provide that the Company’s directors may implement a trading program under Rule 10b5-1 of the Exchange Act. 

2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this
Section 2.5 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition
of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities. 
 2.6 Expenses of
Registration. All expenses (other than Selling Expenses) incurred in connection with registrations, filings, or qualifications pursuant to Section 2, including all registration, filing, and qualification fees; printers’ and
accounting fees; fees and disbursements of counsel for the Company; and, to the extent the Deerfield Investor is participating in a registration pursuant to Section 2, the reasonable and documented out-of-pocket fees and disbursements of
one counsel for the Deerfield Investor (“Selling Holder Counsel”), shall be borne and paid by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to Subsection 2.1 if the registration request is subsequently withdrawn at the request of the Initiating Holders (in which case all selling Holders shall bear such expenses pro rata based upon the number
of Registrable Securities that were to be included in the withdrawn registration), unless the Initiating Holders agree to forfeit their right to one registration pursuant to Subsections 2.1(a) or 2.1(b), as the case may be;
provided further that if, at the time of such withdrawal, such Initiating Holders shall have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their
request and have withdrawn the request with reasonable promptness after learning of such information then the Initiating Holders shall not forfeit their right to one registration pursuant to 

  
 14. 

 
Subsections 2.1(a) or 2.1(b). All Selling Expenses relating to Registrable Securities registered pursuant to this Section 2 shall be borne and paid by the Holders
pro rata on the basis of the number of Registrable Securities registered on their behalf. 
 2.7 Delay of Registration. No
Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this
Section 2. 
 2.8 Indemnification. If any Registrable Securities are included in a registration statement under this
Section 2: 
 (a) To the extent permitted by law, the Company will indemnify and hold harmless each selling Holder, and
the partners, members, officers, directors, and shareholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each such Holder; and each Person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person any legal or other expenses
reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this
Subsection 2.8(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be
liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling Person, or
other aforementioned Person expressly for use in connection with such registration. 
 (b) To the extent permitted by law, each
selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the registration statement, each Person (if any), who controls the Company within the meaning of
the Securities Act, legal counsel and accountants for the Company, any underwriter (as defined in the Securities Act), any other Holder selling securities in such registration statement, and any controlling Person of any such underwriter or other
Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder
expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending
any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Subsection 2.8(b) shall not apply to amounts paid in settlement of any such
claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further that in no event shall the aggregate amounts payable by any Holder by way of
indemnity or contribution under Subsections 2.8(b) and 2.8(d) exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by
such Holder. 

  
 15. 

 (c) Promptly after receipt by an indemnified party under this Subsection 2.8
of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party
under this Subsection 2.8, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate
jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified
parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. 

(d) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either:
(i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Subsection 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Subsection 2.8 provides for indemnification in
such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Subsection 2.8, then, and in each such case, such parties will contribute to
the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified
party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party
and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the
indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case (x) no
Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (y) no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a
Holder’s liability pursuant to this Subsection 2.8(d), when combined with the amounts paid or payable by such Holder pursuant to Subsection 2.8(b), exceed the proceeds from the offering received by such Holder (net of
any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder. 

  
 16. 

 (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification
and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the
obligations of the Company and Holders under this Subsection 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall survive the termination of
this Agreement. 
 2.9 Reports Under Exchange Act. With a view to making available to the Holders the benefits of SEC Rule 144 and
any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall: 

(a) make and keep available adequate current public information, as those terms are understood and defined in SEC Rule 144, at all
times after the effective date of the registration statement filed by the Company for the IPO; 
 (b) use commercially reasonable
efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and 

(c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) to the extent
accurate, a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the registration statement filed by the Company for the IPO), the
Securities Act, and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after the Company so
qualifies); (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company; and (iii) such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time after the Company has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after
the Company so qualifies to use such form). 
 2.10 Limitations on Subsequent Registration Rights. 

(a) Except to the extent permitted by paragraph (b) of this Section 2.9, from and after the date of this Agreement,
the Company shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, which majority must include the Deerfield Investor, enter into any agreement with any holder or prospective holder
of any securities of the Company that (i) would allow such holder or prospective holder to include such securities in any registration unless, under the terms of such 

  
 17. 

 
agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the number of the
Registrable Securities of the Deerfield Investor that are included; or (ii) allow such holder or prospective holder to initiate a demand for registration of any securities held by such holder or prospective holder; 

(b) In connection with any financings permitted pursuant to the terms of subsections (ix) and (xii) of the definition of
“Permitted Indebtedness” hereunder in which the Person or Persons providing such financing receive Common Stock or any securities that are directly or indirectly convertible into Common Stock, the Company may grant to the
holders or prospective holders providing such financing (referred to as “Subordinated Holders”) the right to initiate a demand for registration of such Common Stock held by Subordinated Holders provided that
(i) such grant and the terms applicable thereto are on arms’ length terms; (ii) in connection therewith, the Company and the Subordinated Holders enter into a registration rights agreement in customary form that does not conflict with
the registration rights or procedures provided under this Agreement; and (iii) if the underwriter(s) determine that less than all of the securities requested to be registered pursuant to such registration can be included in such offering, the
number of shares to be included in such registration by Subordinated Holders shall be limited as follows: 
 (1) first, the Other
Securities (except the Other Securities held by the Subordinated Holders) shall be excluded from such registration to the extent so required by such limitation such that the number of shares to be included by such holders of Other Securities shall
be determined on a pro rata basis based upon the aggregate number of Other Securities held by each such holder seeking registration; 

(2) second, to the extent further limitation is required by the underwriters, the Registrable Securities not held by the Deerfield
Investor or Cowen shall be excluded from such registration to the extent so required by such limitation such that the number of shares to be included by such Holders shall be determined on a pro rata basis based upon the aggregate number of
Registrable Securities held by Holders seeking registration (other than the Deerfield Investor and Cowen); 
 (3) third, to the
extent further limitation is required by the underwriter(s), the Primary Securities shall be excluded from such registration to the extent so required by such limitation; and 

(4) fourth, to the extent further limitation is required by the underwriters(s), the Other Securities held by Subordinated Holders and
the Registrable Securities held by the Deerfield Investor and Cowen shall be excluded from such registration pro rata to the extent so required by such limitation such that the number of shares to be included by the Subordinated Holders, the
Deerfield Investor and Cowen shall be determined on a pro rata basis based upon the aggregate number of Other Securities and Registrable Securities held by the Subordinated Holders, the Deerfield Investor and Cowen, respectively. 

  
 18. 

 To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters
may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. 
 2.11
“Market Stand-off” Agreement.  
 (a) Each Holder hereby agrees that it
will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the IPO, and ending on the date specified by the Company and the managing underwriter (such period

Exchange Act, and (11) any transfer to the underwriters in the IPO pursuant to the underwriting agreement, provided, further, that in the case of any transfer described in clause (1), (2), (3) or (4) above, it shall be a
condition to the transfer that (A) the transferee executes and delivers to the managing underwriters, acting on behalf of the underwriters, not later than one business day prior to such transfer, a written agreement, in substantially the form
of this Section 2.11 (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the Holder and not to the immediate family
of the transferee) and otherwise satisfactory in form and substance to the managing underwriters, and (B) if the Holder is required to file a report under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of

the sale or other bona fide transfer in a single transaction of all or substantially all of the Holder’s capital stock, partnership interests, membership interests or other similar equity interests, as the case may be, or all or substantially

or exercisable or exchangeable for Common Stock or Beneficially Owned Shares during the Lock-Up Period, the Holder shall include a statement in such report to the effect that such transfer is being made pursuant to a right of repurchase or a right
of first refusal by the Company. For purposes of this paragraph, “immediate family” shall mean a spouse, child, grandchild or other lineal descendant (including by adoption), father, mother, brother or sister of the Holder;
and “affiliate” shall have the meaning set forth in Rule 405 under the Securities Act. 
 (c) Each Holder
further agrees that (1) it will not, during the Lock-Up Period, make any demand or request for or exercise any right, including, but not limited to, any such rights of the Holder described in Section 2 hereof, with respect to the
registration under the Securities Act of any shares of Common Stock or other Beneficially Owned Shares or any securities convertible into or exercisable or exchangeable for Common Stock or other Beneficially Owned Shares, and (2) the Company
may, with respect to any Common Stock or other Beneficially Owned Shares or any securities convertible into or exercisable or exchangeable for Common Stock or other Beneficially Owned Shares owned or held (of record or beneficially) by the Holder,
cause the transfer agent or other registrar to enter stop transfer instructions and implement stop transfer procedures with respect to such securities during the Lock-Up Period. 

(d) The underwriters in connection with such registration are intended third-party beneficiaries of this Subsection 2.11
and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such
registration that are consistent with this Subsection 2.11 or that are necessary to give further effect thereto. 
 (e)
Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Holders subject to such agreements, based on the number of shares subject to such
agreements. 
 2.12 Restrictions on Transfer. 

(a) The Preferred Stock and the Registrable Securities shall not be sold, pledged, or otherwise transferred, and the Company shall not
recognize and shall issue stop-transfer instructions to its transfer agent with respect to any such sale, pledge, or transfer, 

  
 21. 

 
except upon the conditions specified in this Agreement, which conditions are intended to ensure compliance with the provisions of the Securities Act. A transferring Holder will cause any proposed
purchaser, pledgee, or transferee of the Preferred Stock and the Registrable Securities held by such Holder to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement. 

(b) Each certificate, instrument, or book entry representing (i) the Preferred Stock, (ii) the Registrable Securities, and
(iii) any other securities issued in respect of the securities referenced in clauses (i) and (ii), upon any stock split, stock dividend, recapitalization, merger, consolidation, or similar event, shall (unless otherwise permitted by the
provisions of Subsection 2.12(c)) be notated with a legend substantially in the following form: 
 THE SECURITIES REPRESENTED
HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SHARES MAY NOT BE SOLD, PLEDGED, OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID EXEMPTION FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT. 
 THE SECURITIES REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 The Holders consent to
the Company making a notation in its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer set forth in this Subsection 2.12. 

(c) The holder of such Restricted Securities, by acceptance of ownership thereof, agrees to comply in all respects with the provisions
of this Section 2.12. Before any proposed sale, pledge, or transfer of any Restricted Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transaction, the Holder thereof shall
give notice to the Company of such Holder’s intention to effect such sale, pledge, or transfer. Each such notice shall describe the manner and circumstances of the proposed sale, pledge, or transfer in sufficient detail and, if reasonably
requested by the Company, shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall, be reasonably satisfactory to the Company, addressed to the Company, to the
effect that the proposed transaction may be effected without registration under the Securities Act; (ii) a “no action” letter from the SEC to the effect that the proposed sale, pledge, or transfer of such Restricted Securities without
registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto; or (iii) any other evidence reasonably satisfactory to counsel to the Company to the effect that the proposed sale, pledge, or
transfer of the Restricted Securities may be effected without registration under the Securities Act, whereupon the Holder of such Restricted Securities shall be entitled to sell, 

  
 22. 

 
pledge, or transfer such Restricted Securities in accordance with the terms of the notice given by the Holder to the Company. The Company will not require such a legal opinion or “no
action” letter (x) in any transaction in compliance with SEC Rule 144; or (y) in any transaction in which such Holder distributes Restricted Securities to an Affiliate of such Holder for no consideration; provided that each
transferee agrees in writing to be subject to the terms of this Subsection 2.12. Each certificate, instrument, or book entry representing the Restricted Securities transferred as above provided shall be notated with, except if such
transfer is made pursuant to SEC Rule 144, the appropriate restrictive legend set forth in Subsection 2.12(b), except that such certificate instrument, or book entry shall not be notated with such restrictive legend if, in the opinion of
counsel for such Holder and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act. 

(d) Notwithstanding the foregoing, the provisions of this Section 2.12 shall not apply to the Deerfield Warrants or
Deerfield Convertible Notes (including any transfer thereof) or any Registrable Securities issuable (directly or indirectly) under the terms of the Deerfield Warrants or Deerfield Convertible Notes and any restrictive legends otherwise provided
under this Section 2.12 shall be removed upon an IPO. 
 2.13 Termination of Registration Rights. 

(a) The right of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to
Subsections 2.1 or 2.2 shall terminate upon the earliest to occur of: 
 the closing of a Deemed Liquidation Event, as such
term is defined in the Company’s Amended and Restated Certificate of Incorporation, as amended from time to time, (the “Certificate”); 

such time as Rule 144 or another similar exemption under the Securities Act is available for the sale of all of such Holder’s shares
without limitation during a three-month period without registration; and 
 the two-year anniversary of the IPO. 

(b) Notwithstanding the provisions of Subsection 2.13(a) hereof, the right of the Deerfield Investor to request registration or
inclusion of any Registrable Securities held by it in any registration pursuant to Subsections 2.1 or 2.2 shall terminate upon the earlier of (i) such time that all outstanding Deerfield Warrants and Deerfield Convertible Notes
have been exercised or converted, as applicable, in full and Rule 144 or another similar exemption under the Securities Act is available for the sale of all Registrable Securities held the Deerfield Investor without limitation during a three-month
period without registration or (ii) six-months following the later to occur of (x) the expiration of the Deerfield Warrants and (y) payment in full or termination of the Deerfield Convertible Notes. 

3. Information Rights. 

3.1 Delivery of Financial Statements. (a) If the Company is not required to file reports pursuant to the Exchange Act, the Company
shall deliver to each Deerfield Investor 

  
 23. 

 
quarterly unaudited consolidated financial statements within sixty (60) days after the end of each of the first three fiscal quarters of the Company following the date of this Agreement and
within forty-five (45) days after the end of each fiscal quarter of each fiscal year thereafter, and, commencing with the fiscal year ending December 31, 2015, audited annual consolidated financial statements within one hundred twenty
(120) days after the end of each year prepared in accordance with GAAP in the United States or such other jurisdiction as may be applicable with a report thereon by the Company’s independent certified public accountants; (b) if the
Company is required to file reports pursuant to Section 13 or 15(d) of the Exchange Act, the Company will timely file with the SEC (subject to appropriate extensions made under Rule 12b-25 of the Exchange Act) any annual reports, quarterly
reports and other periodic reports required to be filed pursuant to Section 13 or 15(d) of the Exchange Act; and (c) the Company will provide to the Deerfield Investor copies of all documents, reports, financial data and other information
that the Deerfield Investor may reasonably request, including amendments to its Certificate and Bylaws promptly after their effectiveness. 

If, for any period, the Company has any subsidiary, then in respect of such period the financial statements delivered pursuant to the
foregoing sections shall be the consolidated and consolidating financial statements of the Company and all such consolidated subsidiaries. 

3.2 Inspection. During regular business hours and upon reasonable notice the Company will permit the Deerfield Investor to,
(x) not more than once each calendar quarter at their own expense, visit and inspect any of the properties, examine the books of account and records of the Company or its subsidiaries and (y) discuss the Company’s affairs, finances
and accounts with its officers; provided, however, that the Company shall not be obligated pursuant to this Subsection 3.2 to provide access to any information that it reasonably and in good faith considers to be a trade secret or
confidential information (unless covered by an enforceable confidentiality agreement, in form acceptable to the Company) or the disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel. 

3.3 Termination of Information. The covenants set forth in Subsection 3.1 and Subsection 3.2 shall terminate
and be of no further force or effect (i) immediately before the consummation of the IPO, or (ii) when the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act, or
(iii) upon a Deemed Liquidation Event, as such term is defined in the Certificate, whichever event occurs first. 
 3.4
Confidentiality. Each Investor agrees that such Investor will keep confidential and will not disclose, divulge, or use for any purpose (other than to monitor its investment in the Company) any confidential information obtained from the Company
pursuant to the terms of this Agreement (including notice of the Company’s intention to file a registration statement), unless such confidential information (a) is known or becomes known to the public in general (other than as a result of
a breach of this Subsection 3.4 by such Investor), (b) is or has been independently developed or conceived by the Investor without use of the Company’s confidential information, or (c) is or has been made known or
disclosed to the Investor by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that an Investor may disclose confidential information (i) to its attorneys,
accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company; (ii) to any prospective 

  
 24. 

 
purchaser of any Registrable Securities from such Investor, if a transfer to such prospective purchase is permitted and such prospective purchaser agrees to be bound by the provisions of this
Subsection 3.4; (iii) to any existing or prospective Affiliate, partner, member, shareholder, or wholly owned subsidiary of such Investor in the ordinary course of business, provided that such Investor informs such Person
that such information is confidential and directs such Person to maintain the confidentiality of such information; or (iv) as may otherwise be required by law, and provided, further, that the Investor promptly notifies the Company of
such disclosure and takes reasonable steps to minimize the extent of any such required disclosure. 
 4. Rights to Future Stock
Issuances. 
 4.1 Right of First Offer. Subject to the terms and conditions of this Subsection 4.1 and applicable
securities laws, if the Company proposes to offer or sell any New Securities, the Company shall first offer such New Securities to each Major Investor. A Major Investor shall be entitled to apportion the right of first offer hereby granted to it in
such proportions as it deems appropriate, among (i) itself, (ii) its Affiliates and (iii) its beneficial interest holders, such as limited partners, members or any other Person having “beneficial ownership,” as such term is
defined in Rule 13d-3 promulgated under the Exchange Act, of such Major Investor (“Investor Beneficial Owners”); provided that each such Affiliate or Investor Beneficial Owner (x) agrees to enter into this
Agreement and each of the Voting Agreement and Amended and Restated Right of First Refusal and Co-Sale Agreement of even date herewith, as amended from time to time, among the Company, the Investors and the other parties named therein, as a
“Major Investor” under each such agreement and (y) agrees to purchase at least such number of New Securities as are allocable hereunder to the Major Investor holding the fewest number of Preferred Stock and any other
Derivative Securities. 
 (a) The Company shall give notice (the “Offer Notice”) to each Major Investor,
stating (i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities. 

(b) By notification to the Company within twenty (20) days after the Offer Notice is given, each Major Investor may elect to
purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the Common Stock then held by such Major Investor (including all shares of Common
Stock then issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Stock and any other Derivative Securities then held by such Major Investor, without regard, in the case of the Deerfield Warrants and
Deerfield Convertible Notes, to any limitation on exercise or conversion thereunder) bears to the total Common Stock of the Company then held by all the Major Investors (including all shares of Common Stock issuable (directly or indirectly) upon
conversion and/or exercise, as applicable, of the Preferred Stock and any other Derivative Securities then held by the Major Investors). At the expiration of such twenty (20) day period, the Company shall promptly notify each Major Investor
that elects to purchase or acquire all the shares available to it (each, a “Fully Exercising Investor”) of any other Major Investor’s failure to do likewise. During the ten (10) day period commencing after the
Company has given such notice, each Fully Exercising Investor may, by giving notice to the Company, elect to purchase or acquire, in addition to the number of shares 

  
 25. 

 
specified above, up to that portion of the New Securities for which Major Investors were entitled to subscribe but that were not subscribed for by the Investors which is equal to the proportion
that the Common Stock issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of Preferred Stock and any other Derivative Securities then held, by such Fully Exercising Investor bears to the Common Stock
issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Stock and any other Derivative Securities then held, by all Fully Exercising Investors who wish to purchase such unsubscribed
shares. The closing of any sale pursuant to this Subsection 4.1(b) shall occur within the later of ninety (90) days of the date that the Offer Notice is given and the date of initial sale of New Securities pursuant to
Subsection 4.1(c). 
 (c) If all New Securities referred to in the Offer Notice are not elected to be purchased or
acquired as provided in Subsection 4.1(b), the Company may, during the thirty (30) day period following the expiration of the periods provided in Subsection 4.1(b), offer and sell the remaining unsubscribed portion of
such New Securities to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of the New Securities
within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the
Major Investors in accordance with this Subsection 4.1. 
 (d) The right of first offer in this
Subsection 4.1 shall not be applicable to (i) Exempted Securities (as defined in the Certificate); and (ii) shares of Common Stock issued in the IPO. 

4.2 Termination. The covenants set forth in Section 4.1 shall terminate and be of no further force or effect
(i) immediately before the consummation of the IPO or (ii) upon a Deemed Liquidation Event, as such term is defined in the Certificate, whichever event occurs first. 

5. Additional Covenants 

5.1 The Company shall use its commercially reasonable efforts to obtain from financially sound and reputable insurers, Directors and
Officers liability insurance and term “key-person” insurance on Travis Mickle, in an amount and on terms and conditions satisfactory to the Board of Directors, and will use commercially reasonable efforts to cause such insurance policies
to be maintained until such time as the Board of Directors determines that such insurance should be discontinued. The key-person policy shall name the Company as loss payee, and neither policy shall be cancelable by the Company without prior
approval by the Board of Directors, including the Series D Directors (as defined in the Certificate). Notwithstanding any other provision of this Section 5.1 to the contrary, for so long as a Series D Director is serving on the Board of
Directors, the Company shall not cease to maintain a Directors and Officers liability insurance policy in an amount of at least $10 million unless approved by such Series D Director, and the Company shall annually, within one hundred twenty
(120) days after the end of each fiscal year of the Company, deliver to the Deerfield Investor and any Major Investor who holds greater than 1,500,000 shares (as adjusted for any stock split, stock dividend, combination, or

  
 26. 

 
other recapitalization or reclassification effected after the date hereof) of the Company’s Series D-1 Preferred Stock a certification that such a Directors and Officers liability insurance
policy remains in effect. Each Key Holder hereby covenants and agrees that, to the extent such Key Holder is named under such key-person policy, such Key Holder will execute and deliver to the Company, as reasonably requested, a written notice and
consent form with respect to such policy. 
 5.2 Unless otherwise determined by the Board of Directors, the Company will cause
(i) each person now or hereafter employed by it or by any subsidiary (or engaged by the Company or any subsidiary as a consultant/independent contractor) with access to confidential information and/or trade secrets to enter into a nondisclosure
and proprietary rights assignment agreement; and (ii) each Key Employee to enter into a one (1) year noncompetition and nonsolicitation agreement, substantially in the form approved by the Board of Directors. In addition, the Company shall
not amend, modify, terminate, waive, or otherwise alter, in whole or in part, any of the above-referenced agreements or any restricted stock agreement between the Company and any employee, without the unanimous consent of the Series D Directors, if
any. 
 5.3 Unless otherwise approved by the Board of Directors, including the Series D Directors, all future employees and
consultants of the Company who purchase, receive options to purchase, or receive awards of shares of the Company’s capital stock after the date hereof shall be required to execute restricted stock or option agreements, as applicable,
(i) providing for vesting of shares over a four (4) year period, with the first twenty-five percent (25%) of such shares vesting following twelve (12) months of continued employment or service, and the remaining shares vesting in
equal monthly installments over the following thirty-six (36) months and (ii) providing for a market stand-off provision substantially similar to that in Subsection 2.11. 

5.4 The Company shall use commercially reasonable efforts to cause the shares of Senior Preferred Stock issued pursuant to the Purchase
Agreement or the Facility Agreement or issuable upon conversion of the Deerfield Convertible Notes or upon exercise of the Deerfield Warrants, as well as any shares of Common Stock into which any such shares of Senior Preferred Stock are converted,
within the meaning of Section 1202(f) of the Internal Revenue Code (the “Code”), to constitute “qualified small business stock” as defined in Section 1202(c) of the Code; provided, however that such
requirement shall not be applicable if the Board of Directors determines, in its good faith business judgment, that such qualification is inconsistent with the best interests of the Company. The Company shall submit to its shareholders (including
the Investors) and to the Internal Revenue Service any reports that may be required under Section 1202(d)(1)(C) of the Code and the regulations promulgated thereunder. In addition, within twenty (20) business days after any Investor’s
written request therefor, the Company shall, at its option, either (i) deliver to such Investor a written statement indicating whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business
stock” as defined in Section 1202(c) of the Code or (ii) deliver to such Investor such factual information in the Company’s possession as is reasonably necessary to enable such Investor to determine whether (and what portion of)
such Investor’s interest in the Company constitutes “qualified small business stock” as defined in Section 1202(c) of the Code. 

  
 27. 

 5.5 Unless otherwise determined by the vote of a majority of the directors then in office,
the Board of Directors shall meet at least quarterly in accordance with an agreed-upon schedule. The Company shall reimburse the nonemployee directors for all reasonable out-of-pocket travel expenses incurred (consistent with the Company’s
travel policy) in connection with attending meetings of the Board of Directors. The Company shall cause to be established, as soon as practicable and will maintain, an audit and compensation committee, each of which shall consist solely of
non-management directors. Each non-employee director shall be entitled to attend the meetings of any committee of the Board of Directors. 

5.6 If the Company or any of its successors or assignees consolidates with or merges into any other Person and is not the continuing or
surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the obligations of the Company with respect to indemnification
of members of the Board of Directors as in effect immediately before such transaction, whether such obligations are contained in the Company’s Bylaws, the Certificate, or elsewhere, as the case may be. 

5.7 The Company hereby acknowledges that one (1) or more of the directors nominated to serve on the Board of Directors by the
Investors (each a “Fund Director”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more of the Investors and certain of their Affiliates (collectively, the
“Fund Indemnitors”). The Company hereby agrees (a) that it is the indemnitor of first resort (i.e., its obligations to any such Fund Director are primary and any obligation of the Fund Indemnitors to advance expenses or
to provide indemnification for the same expenses or liabilities incurred by such Fund Director are secondary), (b) that it shall be required to advance the full amount of expenses incurred by such Fund Director and shall be liable for the full
amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf of any such Fund Director to the extent legally permitted and as required by the Certificate or Bylaws of the Company (or any agreement between the
Company and such Fund Director), without regard to any rights such Fund Director may have against the Fund Indemnitors, and, (c) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund
Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of any such Fund Director with respect to any claim for which
such Fund Director has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery
of such Fund Director against the Company. 
 5.8 The Company hereby agrees and acknowledges that the Deerfield Investor and Cowen
(each, together with its Affiliates) (collectively, the “Institutional Investors”) are professional investment institutions, and as such invests in numerous portfolio companies, some of which may be deemed competitive with
the Company’s business (as currently conducted or as currently propose to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, the Institutional Investors shall not be liable to the Company for any claim
arising out of, or based upon, (i) the investment by the Institutional Investors in any entity competitive with the Company, or (ii) actions taken by any partner, officer or other representative of the Institutional Investors to assist any
such competitive company, whether or 

  
 28. 

 
not such action was taken as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a detrimental effect on the Company; provided,
however, that the foregoing shall not relieve (x) any of the Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained pursuant to this Agreement, or (y) any director
or officer of the Company from any liability associated with his or her fiduciary duties to the Company. 
 5.9 Deerfield Approval
Rights. The Company shall not (and shall not permit any subsidiary to), either directly or indirectly, by amendment, merger, consolidation or otherwise, do any of the following without (in addition to any other vote required by law, the
Certificate or any agreement to which the Company is a party) the prior written consent of the Deerfield Investor: 
 (a) incur
Indebtedness other than Permitted Indebtedness; 
 (b) create, or hold capital stock in, any subsidiary that is not wholly-owned,
either directly or through one or more subsidiaries, by the Company, or sell, transfer or otherwise dispose of any capital stock of any direct or indirect subsidiary of the Company; 

(c) effect an IPO; provided, however, that this Section 5.9(c) shall not apply (i) to a Qualified IPO,
(ii) after June 30, 2016 or (iii) after the FDA has accepted the Company’s NDA for KP201 for review, the Company has delivered a Disbursement Request (as defined in the Facility Agreement) for the Second Disbursement (as defined
in the Facility Agreement) and the Second Disbursement under the Facility Agreement has not been effected; 
 (d) issue any equity
securities, including, but not limited to the issuance of rights to purchase securities, to the Company’s employees, directors, consultants or advisory board members as compensation; provided, however, that such approval shall not be
required for the issuance, grant or award of any equity securities to the Company’s employees, directors, consultants and advisory board members, so long as the equity securities issued, granted or awarded are approved by the Board of Directors
or its compensation committee, and the aggregate number of such equity securities granted and Common Stock issued in connection therewith do not exceed 6,000,000 in the aggregate, including the 4,264,000 options already granted pursuant to the terms
of the Company’s existing option plan; and 
 (e) sell, lease, transfer, market, license, pledge, encumber or otherwise dispose
of (in a single transaction or a series of related transactions): 
 all or substantially all of its assets; or 

any of its material Intangible Assets, if, and only if, the Board of Directors does not unanimously approve such transaction. 

5.10 Termination of Covenants. The covenants set forth in this Section 5, except for Subsections 5.7 and
5.8, shall terminate and be of no further force or effect (i) immediately before the consummation of an IPO, or (iii) upon a Deemed Liquidation Event, as such term is defined in the Certificate, whichever event occurs first. 

  
 29. 

 6. Miscellaneous. 

6.1 Successors and Assigns. The rights under this Agreement may be assigned (but only with all related obligations) (i) by a Holder
to a transferee of Registrable Securities that is an Affiliate, partner, member, shareholder or wholly-owned subsidiary of a Holder; or (ii) by a Holder to a transferee of Registrable Securities that, after such transfer, holds at least 50,000
shares of Registrable Securities (subject to appropriate adjustment for stock splits, stock dividends, combinations, and other recapitalizations) or (iii) by the Deerfield Investor if immediately following such transfer, the Deerfield Investor
continues to hold the Threshold Amount or any such transferee of Deerfield Warrants, Deerfield Convertible Notes or other Registrable Securities held by Deerfield and its Affiliates hold, immediately following such transfer, Deerfield Warrants,
Deerfield Convertible Notes or other Registrable Securities held by Deerfield in which the shares of Series D Preferred Stock or Common Stock issuable upon exercise or conversion of such Deerfield Warrants and Deerfield Convertible Notes (without
regard to any limitation of the number of shares issuable on exercise or conversion of such Deerfield Warrants and Deerfield Convertible Notes), represent at least the Threshold Amount; provided, however, that (x) the Company is, within
a reasonable time after such transfer, furnished with written notice of the name and address of such transferee and the Registrable Securities with respect to which such rights are being transferred; (y) such transferee agrees in a written
instrument delivered to the Company to be bound by and subject to the terms and conditions of this Agreement, including the provisions of Subsection 2.11 and (z) such transferee is not a Competitor of the Company. For the purposes
of determining the number of shares of Registrable Securities held by a transferee, the holdings of a transferee that is an Affiliate or shareholder of a Holder shall be aggregated together and with those of the transferring Holder. The terms and
conditions of this Agreement inure to the benefit of and are binding upon the respective successors and permitted assignees of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and permitted assignees any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein. 

6.2 Governing Law. This Agreement shall be governed by the internal law of the State of New York.

www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

the Key Holders and all of their respective successors and permitted assigns whether or not such party, assignee or other shareholder entered into or approved such amendment, modification, termination or waiver. Notwithstanding the foregoing,
(i) this Agreement may not be amended, modified or terminated and the observance of any term hereunder may not be waived with respect to any Investor or Key Holder without the written consent of such Investor or Key Holder unless such
amendment, modification, termination or waiver applies to all Investors and Key Holders, respectively, in the same fashion (it being agreed that a waiver of the provisions of Section 4 with respect to a particular transaction shall be
deemed to apply to all Investors in the same fashion if such waiver does so by its terms, notwithstanding the fact that certain Investors may nonetheless, by agreement with the Company, purchase securities in such transaction) and (ii) the
consent of the Key Holders shall not be required for any amendment, modification, termination or waiver if such amendment, modification, termination or waiver does not apply to the Key Holders. The Company shall give prompt written notice of any
amendment, modification or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, modification, termination or waiver. No waivers of or exceptions to any term, condition or provision of this

or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, and such invalid, illegal, or unenforceable provision shall be reformed and construed so that it will be valid,
legal, and enforceable to the maximum extent permitted by law. 
 6.8 Aggregation of Stock. All shares of Registrable Securities held

 31. 

 6.9 Additional Investors. Notwithstanding anything to the contrary contained herein, if
the Company issues additional shares of the Company’s Series D or any Deerfield Convertible Notes or Deerfield Warrants or Series D-1 Preferred Stock after the date hereof pursuant to the Facility Agreement, Purchase Agreement or upon exercise

party to this Agreement by executing and delivering an additional counterpart signature page to this Agreement, and thereafter shall be deemed an “Investor” for all purposes hereunder. No action or consent by the Investors
shall be required for such joinder to this Agreement by such additional Investor, so long as such additional Investor has agreed in writing to be bound by all of the obligations as an “Investor” hereunder. 

6.10 Entire Agreement. This Agreement (including any Schedules and Exhibits hereto) constitutes the full and entire understanding and
agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled.

personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding

 32. 

 6.12 Delays or Omissions. No delay or omission to exercise any right, power, or remedy
accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or
acquiescence to any such breach or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All

	            Conversion Amount            
	            Conversion Price            

 (c) Mechanics of Conversion. The conversion of this Note shall be conducted in the following manner:

 (i) Holder’s Delivery Requirements. To convert a Conversion Amount into Conversion Shares (other than Required Conversion
Shares) on any date (the “Conversion Date”, which shall also refer to the date of the Required Conversion Notice), the Holder shall (A) transmit by facsimile or electronic mail (or otherwise deliver), for receipt on or prior to
5:00 p.m. New York City time on such date, a copy of an executed conversion notice in the form attached hereto as Exhibit A (the “Conversion Notice”) to the offices of the Company, 2656 Crosspark Road, Suite 100, Carolville,
IA 52241 (Attention: Chief Executive Officer, Fax: (319) 665-2577, Email: rjohnson@kempharm.com), or such other address, facsimile number or email address as the Company may designate in writing, and (B) if required by
Section 2(c)(vi), surrender to a common carrier for delivery to the Company, no later than three (3) Business Days after the Conversion Date, the original Note being converted (or an indemnification undertaking in customary form
with respect to this Note in the case of its loss, theft or destruction). 
 (ii) Company’s Response. Upon receipt or deemed
receipt by the Company of a copy of a Conversion Notice or upon the date of a Required Conversion Notice (as defined below), as applicable, the Company (I) shall as soon as practicable send, via

  
 6. 

 
facsimile, a confirmation of receipt of such Conversion Notice to the Holder and the Company’s designated transfer agent (the “Transfer Agent”), if applicable, which
confirmation shall constitute an instruction to any such Transfer Agent to process such Conversion Notice or Required Conversion Notice in accordance with the terms herein and (II) (A) in the case of a conversion prior to an IPO Event, on or
before the fifthteenth (15th) Business Day following the date of receipt or deemed receipt by the Company of such Conversion Notice, and (B) in the case of a conversion after an IPO
Event, on or before the third (3rd) Business Day following the date of receipt or deemed receipt by the Company of such Conversion Notice or the date of the Required Conversion Notice, as the
case may be (the “Share Delivery Date”), issue and deliver to the address as specified in the Conversion Notice or otherwise specified by the Holder, a stock certificate, registered in the name of the Holder or its designee, for the
number of Conversion Shares to which the Holder shall be entitled. If this Note is submitted for conversion, as may be required by Section 2(c)(vi), and the Principal represented by this Note is greater than the Principal being
converted, then the Company shall, as soon as practicable and in no event later than (1) in the case of a conversion prior to an IPO Event, fifteen (15) Business Days after receipt of this Note, or (2), in the case of a conversion after an
IPO Event, three (3) Business Days (the “Note Delivery Date”) and at its own expense, issue and deliver to the Holder a new Note representing the Principal not converted and cancel this Note. 

(iii) Dispute Resolution. In the case of a dispute as to the determination of the Conversion Price or the Major Transaction Note Early
Termination Price (including any determination as to Fair Market Value) or the arithmetic calculation of the Conversion Rate, the Company shall issue, or instruct the Transfer Agent to issue, as applicable, to the Holder the number of Conversion
Shares that is not disputed and shall transmit an explanation of the disputed determinations or arithmetic calculations to the Holder via facsimile within two (2) Business Days of receipt or deemed receipt of the Holder’s Conversion Notice
or other date of determination. If the Holder and the Company are unable to agree upon the determination of the Conversion Price, Major Transaction Note Early Termination Price or arithmetic calculation of the Conversion Rate within one
(1) Business Day of such disputed determination or arithmetic calculation being transmitted to the Holder, then the Company shall promptly (and in any event within two (2) Business Days) submit via facsimile or email (A) the disputed
determination of the Conversion Price or Major Transaction Note Early Termination Price to an independent, reputable investment banking firm agreed to by the Company and the Required Note Holders, or (B) the disputed arithmetic calculation of
the Conversion Rate to the Company’s independent registered public accounting firm, as the case may be. The Company shall use commercially reasonable best efforts to direct the investment bank or the accounting firm, as the case may be, to
perform the determinations or calculations and notify the Company and the Holder of the results no later than two (2) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accounting
firm’s determination or calculation, as the case may be, shall be binding upon all parties absent manifest error. 
 (iv) Record
Holder. The person or persons entitled to receive the Conversion Shares issuable upon a conversion of this Note shall be treated for all purposes as the legal and record holder or holders of such Shares on the Conversion Date, or in the case of

  
 7. 

 
Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions
of, the dispute resolution provisions of Section 2(c)(iii), the first Business Day after the resolution of such bona fide dispute and the fees and expenses of such investment bank or accountant shall be paid by the Company. 

(v) Company’s Failure to Timely Convert. 

(A) Cash Damages. If, on or before the Share Delivery Date, the Company shall fail to issue and deliver a certificate to the Holder
for the number of Conversion Shares (free of any restrictive legend if the Unrestricted Conditions (as defined below) are met) to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount, or if the Company fails to
issue and deliver a new Note representing the Principal to which such Holder is entitled on or before the Note Delivery Date pursuant to Section 2(c)(ii), then in addition to all other available remedies that the Holder may pursue
hereunder and under the Facility Agreement, the Company shall pay additional damages to the Holder for each 30-day period (prorated for any partial period) after the Share Delivery Date such conversion is not timely effected and/or each day after
the Note Delivery Date such Note is not delivered in an amount equal to (x) in the case of a failure to deliver a certificate for the Conversion Shares, one percent (1%) of the Conversion Amount or (y) in the case of a failure to
deliver a new Note, one percent (1%) of the outstanding balance of the new Note. If the Company fails to pay the additional damages set forth in this Section 2(c)(v)(A) within five (5) Business Days of the date incurred, then the
Holder entitled to such payments shall have the right at any time, so long as the Company continues to fail to make such payments, to require the Company, upon written notice, to immediately issue, in lieu of such damages payments described herein,
the number of Shares equal to the quotient of (X) the aggregate amount of the damages payments described in this Section 2(c)(v)(A) divided by (Y) the lower of (i) the Conversion Price in effect on such Conversion Date as
specified by the Holder in the Conversion Note and (ii) the Fair Market Value Price per Conversion Share on the date of the Conversion Notice. 

(B) Void Conversion Notice. If for any reason the Holder has not received all of the Conversion Shares prior to the tenth
(10th) Business Day after the Share Delivery Date (a “Conversion Failure”), then the Holder, upon written notice to the Company (a “Void Conversion Notice”) delivered prior to the receipt of such Conversion
Shares, may void such applicable conversion with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such notice; provided, that the voiding of such conversion shall not
affect the Company’s obligations to make any payments that have accrued prior to the date of such notice pursuant to Section 2(c)(v)(A), 2(c)(v)(C) or otherwise. 

(C) Event of Default. A Conversion Failure shall constitute an Event of Default under the Facility Agreement and entitle the Lenders
to all payments and remedies provided under the Facility Agreement upon the occurrence of an Event of Default. 

  
 8. 

 (vi) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon
conversion or redemption of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless all of the Principal is being converted or redeemed. The Holder and the Company shall
maintain records showing the Principal converted or redeemed and the dates of such conversions or redemptions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note
upon any such partial conversion or redemption. Notwithstanding the foregoing, if this Note is converted or redeemed as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note to the Company,
whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder may request, representing in the aggregate the remaining Principal represented by this Note. The Holder and any
assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion or redemption of any portion of this Note, the Principal of this Note may be less than the principal amount stated
on the face hereof. 
 (d) Taxes. The Company shall pay any and all taxes (excluding income taxes, franchise taxes or other taxes
levied on gross earnings, profits or the like of the Holder) that may be payable with respect to the issuance and delivery of Conversion Shares upon the conversion of this Note. 

(e) Legends. 
 (i)
Restrictive Legend. The Holder understands and agrees that, for so long as required pursuant to the Investor Agreements, any Conversion Shares shall contain the restrictive legends required pursuant to the terms of the Investor Agreements
(the “IA Legends”). The Holder further understands and agrees that (A) until the Conversion Shares have been registered for sale or resale under the Securities Act, (B) are eligible for sale pursuant to Rule 144(b)(1)
under the Securities Act without volume restriction or (C) have been sold pursuant to Rule 144, any Conversion Shares shall bear a restrictive legend (the “Securities Legend”) in substantially the following form (and a
stop-transfer order may be placed against transfer of the certificates for such securities): 
 “THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN
EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION, PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER
APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4(1) AND A HALF” SALE.” 

  
 9. 

 (ii) Removal of Restrictive Legends. The certificates evidencing the Conversion Shares
shall not contain the Securities Legend and no legend (other than the IA Legends, if required under the Investor Agreements) shall apply restricting the transfer thereof (any such legend that the certificates evidencing the Conversion Shares shall
not so contain or that shall not so apply to the Conversion Shares, as applicable, a “Removable Legend”): (A) while a registration statement covering the sale or resale of such security is effective under the Securities Act, or
(B) following any sale of such Conversion Shares pursuant to Rule 144, or (C) if such Conversion Shares are eligible for sale under Rule 144(b)(1) without volume restriction or (D) if transfer restrictions are not required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). The Company shall use best efforts to cause its
counsel to issue a legal opinion to the Transfer Agent promptly at such time as the Unrestricted Conditions have been satisfied, if required by the Transfer Agent to issue a certificate evidencing the Conversion Shares without the Removable Legends.
If the Unrestricted Conditions are met at the time of issuance of the Conversion Shares, then the Conversion Shares shall be issued free of all Removable Legends. The Company agrees that following such time as the Unrestricted Conditions are met, it
will, no later than three (3) Trading Days following the delivery (the “Unlegended Shares Delivery Deadline”) by the Holder to the Company or the Transfer Agent, if applicable, of a certificate representing Conversion Shares
issued with the Removable Legends (such third Trading Day following such delivery, the “Legend Removal Date”), deliver or cause to be delivered to such Holder one or more certificates evidencing such Conversion Shares that do not
contain the Removable Legends and/or a confirmation confirming in respect of such shares that they are free from the Removable Legends. 

(iii) Sale of Unlegended Shares. Holder agrees that the removal of any restrictive legends from any securities as set forth in this
Section 2(e) is predicated upon the Company’s reliance that the Holder will sell such Conversion Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery
requirements, or an exemption therefrom, and that if such securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein. 

(f) Adjustments to Conversion Price. 

(i) Adjustment of Conversion Price upon Issuance of Common Stock, Options, Convertible Securities, Etc. 

(A) If at any time after the Mandatory Conversion Time for so long as this Note is outstanding, the Company (x) issues or sells any
Common Stock, Convertible Securities, warrants, or Options or (y) directly or indirectly effectively reduces the conversion, exercise or exchange price for any Convertible Securities or Options which are currently outstanding, at or to an
effective Per Share Selling Price (as defined below) which is less than the greater of (I) the closing sale price per share of the Common Stock on the principal securities exchange, trading market or quotation system on which shares of Common
Stock are 

  
 10. 

 
then traded, listed or quoted on the Trading Day immediately preceding such issue or sale (“Fair Market Price”), or (II) the Conversion Price, then in each such case the Conversion
Price in effect immediately prior to such issue or sale date, as applicable, shall be automatically reduced effective concurrently with such issue or sale to an amount determined by multiplying the Conversion Price then in effect by a fraction,
(x) the numerator of which shall be the sum of (1) the number of shares of Common Stock outstanding immediately prior to such issue or sale, plus (2) the number of shares of Common Stock which the aggregate consideration received by
the Company for such additional shares would purchase at such Fair Market Price or Conversion Price, as the case may be, and (y) the denominator of which shall be the number of shares of Common Stock of the Company outstanding immediately after
such issue or sale. The foregoing provision shall not apply to any issuances or sales of Common Stock or Convertible Securities (i) pursuant to any Convertible Securities or Options currently outstanding on the date hereof in accordance with
the terms of such Convertible Securities in effect on the date hereof provided that such securities have not been amended since the date hereof to directly or indirectly effectively reduce the conversion, exercise or exchange price for any
Convertible Securities or Options which are currently outstanding, or (ii) any Common Stock issued or issuable upon exercise of any options to employees, officers, directors, consultants and advisors (and any individuals who have accepted an
offer of employment), in each case in connection with any Approved Stock Plan (as defined below). 
 For the purposes of the foregoing adjustments, in the
case of the issuance of any Convertible Securities or Options, the maximum number of shares of Common Stock issuable upon exercise, exchange or conversion of such Convertible Securities or Options shall be deemed to be outstanding, provided that no
further adjustment shall be made upon the actual issuance of Common Stock upon exercise, exchange or conversion of such Convertible Securities or Options, and provided further that to the extent such Convertible Securities or Options expire or
terminate unconverted or unexercised, then at such time the Conversion Price shall be readjusted as if such portion of such Convertible Securities or Options had not been issued. 

For purposes of this Section 2(f), if an event occurs that triggers more than one of the above adjustment provisions, then only one adjustment shall be
made and the calculation method which yields the greatest downward adjustment in the Conversion Price shall be used. 
 (B) Record
Date. If the Company takes a record of the holders of Shares for the purpose of entitling them (1) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (2) to subscribe
for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Shares deemed to have been issued or sold upon the declaration of such dividend or the making
of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 

  
 11. 

 (C) Certain Definitions. For purposes of this Section 2(f), the following
terms have the respective meanings set forth below: 
 (I) “Approved Stock Plan” means any employee benefit plan which has
been duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non- employee directors established for such purpose, pursuant to which the Company’s securities
may be issued to any employee, consultant, advisor, officer or director (or any individual who has accepted an offer of employment) for services provided to the Company, and in all cases, providing for a Conversion Price that is at or above the fair
market value (as defined in such Approved Stock Plan). 
 (II) “Convertible Securities” means any stock or securities
(other than Options) directly or indirectly convertible into or exchangeable or exercisable for shares of Common Stock. 
 (III)
“Exempt Issuances” shall mean: (i) prior to the IPO Event, the actual or deemed issuance of any Exempted Securities (as defined in the Charter), and (ii) on or after the IPO Event, the issuance of (a) any Common Stock
issued or issuable upon exercise of any options to employees, officers, directors, consultants and advisors (and any individuals who have accepted an offer of employment), in each case in connection with any Approved Stock Plan, up to a maximum
amount of Common Stock not to exceed in any one calendar year 5% of the total number of outstanding shares of the Company (as of the beginning of such calendar year, (b) securities upon the exercise, exchange of, conversion or redemption of, or
payment of interest or liquidated or similar damages on, any Common Stock issued hereunder, (c) other securities exercisable, exchangeable for, convertible into, or redeemable for shares of Common Stock issued and outstanding on the date of
this Note, provided that such securities have not been amended since the date of this Note to directly or indirectly increase the number of such securities or to decrease the exercise, exchange or conversion price of such securities (and including
any issuances of securities pursuant to the anti- dilution provisions of any such securities), and (d) the issuance of Common Stock, Options, Convertible Securities, stock appreciation rights, phantom stock rights or other rights with equity
features (collectively, “Management Incentives”) issued or granted to employees, officers, directors, consultants and advisors (and individuals who have accepted an offer of employment), which Management Incentives have been
approved by the Required Note Holders. 
 (IV) “Options” means any rights, warrants or options to subscribe for or
purchase shares of Common Stock or Convertible Securities. 
 (V) “Per Share Selling Price” shall include the amount
actually paid by third parties for each share of Common Stock in a sale or issuance by the Company. In the event a fee is paid by the Company in connection with such transaction directly or indirectly to such third party or its affiliates, any such
fee shall be deducted from the selling price pro rata to all shares sold in the transaction to arrive at the Per Share Selling Price. A sale of shares of Common Stock shall include the sale or issuance of Convertible Securities or Options, and in
such circumstances the Per Share Selling Price of the Common Stock covered thereby shall also include the exercise, exchange or conversion price thereof (in addition to the consideration received by the Company upon such sale or issuance less the
fee amount as 

  
 12. 

 
provided above). In case of any such security issued in a transaction in which the purchase price or the conversion, exchange or exercise price is directly or indirectly subject to adjustment or
reset based on a future date, future trading prices of the Common Stock, specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock, or otherwise (but excluding standard stock
split anti-dilution provisions or weighted-average anti-dilution provisions similar to that set forth herein, provided that any actual reduction of such price under any such security pursuant to such weighted-average anti-dilution provision shall be
included and cause an adjustment hereunder), the Per Share Selling Price shall be deemed to be the lowest conversion, exchange, exercise or reset price at which such securities are converted, exchanged, exercised or reset or might have been
converted, exchanged, exercised or reset, or the lowest adjustment, as the case may be, over the life of such securities. If shares are issued for a consideration other than cash, the Per Share Selling Price shall be the fair value of such
consideration as determined in good faith by independent certified public accountants mutually acceptable to the Company and the Holder. In the event the Company directly or indirectly effectively reduces the conversion, exercise or exchange price
for any Convertible Securities or Options which are currently outstanding, then the Per Share Selling Price shall equal such effectively reduced conversion, exercise or exchange price. 

(ii) Adjustment of Conversion Price upon Subdivision or Combination of Shares. If the Company at any time on or after the Issuance
Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) outstanding Shares into a greater number of Shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the
Company at any time on or after the Issuance Date combines (by combination, reverse stock split or otherwise) its outstanding Shares into a lesser number of Shares, the Conversion Price in effect immediately prior to such combination will be
proportionately increased. 
 (iii) Adjustment of Conversion Price upon a Distribution of Assets. If the Company at any time on or
after the Issuance Date shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of Shares, by way of return of capital or otherwise (including any distribution of cash, stock or other
securities, property or options by way of a dividend, spin-off, reclassification, corporate rearrangement or other similar transaction (a “Distribution”), then, in each such case, the applicable Conversion Prices in effect
immediately prior to the close of business on the date fixed for the determination of holders of Shares entitled to receive the Distribution shall be reduced, effective as of the close of business on such date, to a price determined by multiplying
such applicable Conversion Price by a fraction of which (A) the numerator shall be the Fair Market Value of one Share immediately preceding such date minus the Fair Market Value of the Distribution applicable to one Share, and (B) the
denominator shall be the Fair Market Value of one Share on the Trading Day immediately preceding such date. 
 (iv) Recapitalization or
Reclassification. In the event of any reclassification, recapitalization, reorganization, or change affecting the Shares, or any automatic 

  
 13. 

 
or mandatory conversion of all of the outstanding shares of the class or series of capital stock for which this Note is then convertible (except for a conversion of the Series D Preferred Shares
into Common Stock, which this Note handles by its terms), this Note shall become convertible for the kind and amount of shares of stock and other securities and property receivable in connection with such reclassification, reorganization, change or
conversion by a holder of the same number of Conversion Shares as were purchasable by the Holder pursuant to conversion hereof immediately prior to such reclassification, reorganization, change or conversion. In any such case, appropriate provisions
shall be made with respect to the rights and interest of the Holder so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities and property deliverable upon conversion hereof, and appropriate
adjustments shall be made to the Conversion Price payable hereunder, provided the aggregate Conversion Price shall remain the same. 
 (v)
Adjustment for Tax Purposes. The Company shall be entitled to make such reductions in the Conversion Price, in addition to those otherwise required by this Section 2(f), as the Company’s Board of Directors in its discretion
shall determine to be advisable in order that any stock dividends, subdivisions of shares, distribution of rights to purchase stock or securities, or any distribution of securities convertible into or exchangeable for stock, made after the Issuance
Date by the Company to its stockholders shall not be taxable. 
 (vi) Other Events. If any event occurs of the type contemplated by
the provisions of this Section 2(f) but not expressly provided for by such provisions (including the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of
Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this
Section 2(f). 
 (vii) Notices. Promptly upon any adjustment of the Conversion Price, the Company will give written
notice thereof to the Holder, setting forth in reasonable detail, and certifying, the calculation of such adjustment. The Company will give written notice to the Holder at least ten (10) Business Days prior to the date on which the Company
closes its books or takes a record (I) with respect to any dividend or distribution upon the Common Stock or the Shares, (II) with respect to any pro rata subscription offer to holders of Common Stock or Shares or (III) for determining rights
to vote with respect to any Major Transaction, provided that, if such notice is to be provided after the IPO Event, such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder.
The Company will also give written notice to the Holder with respect to any Major Transaction as provided under Section 3(b) below. 

(g) Adjustments for Diluting Issuances. The number of shares of Common Stock (or the number and type of other securities, as
applicable) issuable upon conversion pursuant to the Charter of the Series D Preferred Shares into which this Note is initially convertible is subject to adjustment, from time to time, in the manner set forth in the Charter and/or Bylaws as if the
Series D Preferred Shares into which this Note is convertible were issued and outstanding on and as of the date of any such required adjustment. The provisions set forth 

  
 14. 

 
in the Charter and/or Bylaws (and any amendment thereto) relating to adjustments to the Common Stock (or the number and type of other securities) into which Series D Preferred Shares are
convertible pursuant thereto in effect as of the date hereof may not be amended, modified or waived, in a manner adverse to the holders of the shares of Series D Preferred Stock, without the prior written consent of the Holder unless (i) such
amendment, modification or waiver applies on its face to all shares of Series D Preferred Stock in the same manner or (ii) such amendment, modification or waiver is approved by the Required Note Holders). Nothing in this subsection
(g) shall in any way derogate from any other rights of the Holder set forth herein. 
 (h) Required Conversion. For the seven
(7) Business Day period following the satisfaction of the Required Conversion Conditions, the Company may notify the Holder in writing (a “Required Conversion Notice”) of its election to require the Holder to convert the entire
principal amount of this Note then outstanding (subject to subsection (i) below) into Conversion Shares (a “Required Conversion”). Following receipt of a Required Conversion Notice, the Holder shall be entitled to receive the
Conversion Shares in respect of such Required Conversion Notice within the time frame set forth in this Section 2 with respect to Conversion Shares. 

(i) Limitations on Conversion. Notwithstanding anything herein to the contrary, the Company shall not issue to the Holder, and the
Holder may not acquire, a number of Conversion Shares upon conversion of this Warrant to the extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by the Holder and its Affiliates and any other persons or
entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which the Holder is a member, but excluding
shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein) would exceed 9.985% of the total
number of the shares of Common Stock then issued and outstanding (the “9.985% Cap”)); provided that the 9.985% Cap shall not apply to the extent that shares of Common Stock are not deemed to constitute “equity securities”
pursuant to Rule 13d-1(i) under the Exchange Act and, provided further, that the 9.985% Cap shall not apply to an exercise effected following receipt of a Major Transaction Notice (as defined below) in respect of a Major Transaction (as defined
below) described in clause (A) of the definition of Major Transaction above in which the Company will not be the surviving entity, until consummation or abandonment of such Major Transaction and, provided further, that the 9.985% Cap shall not
apply to the conversion of this Note into IPO Conversion Shares. For the avoidance of doubt, a conversion hereunder (whether at the election of the Holder or the Company) shall be null and void to the extent the issuance of shares upon such
conversion would violate this subsection (i). 
 3. Rights Upon Major Transaction. Notwithstanding anything contained herein or in
the Facility Agreement to the contrary, in the event that a Major Transaction occurs, then the Holder, at its option, may require the Company to redeem all or any portion of the Principal (and the Interest Amount thereon) outstanding on the
Holder’s Notes for cash in accordance with Section 3(b) below. In the event the Holder shall not have exercised any of its rights under the immediately preceding sentence within the applicable time periods set forth herein, then the

  
 15. 

 
Major Transaction shall be treated as an Assumption (as defined below) in accordance with Section 3(a) below unless the Holder waives its rights under this Section 3 with
respect to such Major Transaction. For the avoidance of doubt, the Holder may waive the above provisions of this Section 3 with respect to any Major Transaction and, without limitation, may elect to convert this Note in accordance with the
other terms hereof prior to any Major Transaction. 
 (a) Assumption. The Company shall not enter into or be party to a Major
Transaction that is to be treated as an Assumption pursuant to this Section 3, unless any Successor Entity assumes in writing all of the obligations of the Company under this Note and provides (a) registration rights that are comparable to
those provided to the initial Holder under the Investor Rights Agreement, if the Successor Entity is not a Publicly Traded Successor Entity, or (B) resale registration rights reasonably acceptable to the Holder, if the Successor Entity is a
Publicly Traded Successor Entity, in accordance with the provisions of this Section 3(a) pursuant to written agreements and instruments in form and substance reasonably satisfactory to the Holder and approved by the Holder prior to such
Major Transaction (not to be unreasonably withheld or delayed), including a security of the Successor Entity evidenced by a written instrument (a “Replacement Note”) substantially similar in form and substance to the Notes,
including, without limitation, representing the appropriate number of shares of the Successor Entity, having similar conversion rights as the Notes (including but not limited to a similar Conversion Price and similar Conversion Price adjustment
provisions based on the price per share or conversion ratio, and taking into account any cash consideration, to be received by the holders of Conversion Shares in the Major Transaction) and providing for conversion into the shares of the Successor
Entity into or for which shares of the same class and series as the Shares are to be converted or exchanged (“Successor Conversion Shares”). Upon the occurrence of any Major Transaction, but only if a Replacement Note has not been
delivered to the Holder in connection therewith, any Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Major Transaction, the provisions of this Note referring to the “Company” shall refer
instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein.
Upon consummation of the Major Transaction, but only if a Replacement Note has not been delivered to the Holder in connection therewith, any Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or
redemption of this Note at any time after the consummation of the Major Transaction, in lieu of the Conversion Shares (or other securities, cash, assets or other property) issuable upon the conversion of the Notes prior to such Major Transaction,
such Successor Conversion Shares in accordance with the provisions of this Note. The provisions of this Section shall apply similarly and equally to successive Major Transactions and shall be applied without regard to any limitations on the
conversion of this Note, including any applicable beneficial ownership limitations. Any assumption of Company obligations under this paragraph shall be referred to herein as an “Assumption.” 

(b) Notice; Major Transaction Early Termination Right. At least fifteen (15) days prior to the consummation of any Major
Transaction, but, in any event, within five (5) Business Days following the first to occur of (x) the date of the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, (y) the

  
 16. 

 
day following the public announcement of such Major Transaction if such announcement is made on and after 4:00 p.m., New York City time, and (z) the date of execution of the definitive
agreement with respect to a Major Transaction, if such agreement is executed prior to an IPO Event, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Major Transaction Notice”).
At any time during the period beginning after the Holder’s receipt of a Major Transaction Notice and ending five (5) Trading Days prior to the consummation of such Major Transaction (the “Early Termination Period”), the
Holder may require the Company to redeem (an “Early Termination Upon Major Transaction”) all or any portion of the outstanding portion of this Note (without regard to any ownership limitations) by delivering written notice thereof
(“Major Transaction Early Termination Notice”) to the Company, which Major Transaction Early Termination Notice shall indicate the portion (the “Early Termination Portion”) of this Note that the Holder is electing
to have so redeemed. The Early Termination Portion shall be redeemed by the Company at a price (the “Major Transaction Note Early Termination Price”) payable in cash equal to the greater of (1) the Principal amount of the Early
Termination Portion and the Interest Amount thereon (additionally including, for this purpose, any interest that would have accrued on such Principal amount from the date of the Major Transaction until the then applicable maturity date of the Note
were such Principal amount on the Note outstanding throughout such period), and (2) the amount of cash payable or distributable per Conversion Share plus the Fair Market Value of any property (other than cash) payable or distributable per
Conversion Share (or the shares of Common Stock into which such Conversion Shares are then convertible, if greater), in each case, pursuant to the terms of the Charter in connection with such Major Transaction. 

(c) Payment of Major Transaction Note Early Termination Price. Following the receipt of a Major Transaction Early Termination Notice
from the Holder, the Company shall not effect a Major Transaction that is being treated as an early termination unless it obtains the written agreement of any Successor Entity that payment of the Major Transaction Note Early Termination Price shall
be made to the Holder prior to or concurrently with consummation of such Major Transaction (subject to any holdbacks or escrows applicable to such payment pursuant to the applicable acquisition agreement and subject to standard non-material
conditions on such payment imposed by such Successor Entity, such as surrender of this Note and delivery of a letter of transmittal and an applicable IRS Form W-9 or applicable W-8, if applicable), and such payment shall be a condition precedent or
concurrent to consummation of such Major Transaction. 
 (d) Injunction. Following the receipt of a Major Transaction Early
Termination Notice from the Holder, in the event that the Company attempts to consummate a Major Transaction without the Major Transaction Note Early Termination Price being paid to the Holder prior to or concurrently with the consummation of such
Major Transaction in accordance with Section 3(c) above, or obtaining any written agreement of the Successor Entity required by Section 3(c) above, the Holder shall have the right to apply for an injunction in any state or
federal courts sitting in the City of New York, borough of Manhattan to prevent the closing of such Major Transaction until the Major Transaction Note Early Termination Price is paid to the Holder, in full. 

  
 17. 

 Any payment determined pursuant to clause (1) of Section 3(b) in connection
with an early termination shall have priority to payments to holders of capital stock in connection with a Major Transaction and to the extent an early termination required by this Section 3 is deemed or determined by a court of
competent jurisdiction to be prepayments of the Note by the Company, such early termination shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 3, until the Major Transaction Note Early
Termination Price is paid in full (excluding any amount subject to escrows or holdbacks and any other contingent consideration that has not accrued), this Note may be converted, in whole or in part, by the Holder into Shares, or in the event the
Conversion Date is after the consummation of a Major Transaction, Successor Conversion Shares pursuant to this Section 3. The parties hereto agree that in the event of the early termination of any portion of the Note under this
Section 3, the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment
opportunity for the Holder. Accordingly, any premium due under this Section 3 is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a
penalty. 
 4. Amendment; Waiver. The terms and provisions of this Note shall not be amended or waived except in a writing signed by
the Company and the Holder, provided that the Company and the Required Note Holders may in writing amend the Notes on behalf of all of the Holders of Notes. 

5. Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Note shall be
cumulative and in addition to all other remedies available under this Note, the Facility Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief). No remedy contained herein shall be deemed a waiver
of compliance with the provisions giving rise to such remedy, and nothing herein shall limit the Holder’s right to pursue actual damages for any failure by the Company to comply with the terms of this Note. The Company covenants to the Holder
that, except as may be set forth in the Facility Agreement, there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the
like (and the computation thereof) shall be the amounts to be received by the Holder thereof and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the
Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 

6. Specific Shall Not Limit General; Construction. No specific provision contained in this Note shall limit or modify any more general
provision contained herein. This Note shall be deemed to be jointly drafted by the Company and all purchasers of Notes pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof. 

  
 18. 

 7. Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder in the
exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or
privilege. 
 8. Notices. Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice
shall be given in accordance with Section 4.1 of the Facility Agreement. 
 9. Restrictions on Transfer. 

(a) Registration or Exemption Required. This Note has been issued in a transaction exempt from the registration requirements of the
Securities Act by virtue of Regulation D and exempt from state registration or qualification under applicable state laws. None of the Note or the Conversion Shares may be pledged, transferred, sold, assigned, hypothecated or otherwise disposed of
except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws including, without limitation, a so-called “4(1) and a half” transaction. 

(b) Assignment. Subject to Section 6.5 of the Facility Agreement, the Holder may sell, transfer, assign, pledge,
hypothecate or otherwise dispose (collectively, “Transfer”) of this Note, in whole or in part. Holder shall deliver a written notice to Company, substantially in the form of the Assignment attached hereto as Exhibit B,
indicating the Person or Persons to whom the Note shall be Transferred and the respective principal amount of the Note to be Transferred to each assignee. The Company shall effect the Transfer within (i) five (5) Business Days, in the case
of a transfer occurring prior to an IPO Event, and (ii) three (3) Business Days, in the case of a transfer occurring following the IPO Event (the “Transfer Delivery Period”), and shall deliver to the assignee(s) designated
by Holder a Note or Notes of like tenor and terms for the appropriate principal amount. This Note and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns of the Holder. The provisions of this Note
are intended to be for the benefit of all Holders from time to time of this Note, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or transfer is a so called “4(1) and
half” transaction, the parties hereto agree that a legal opinion from outside counsel for the Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit C shall be the only requirement to satisfy an
exemption from registration under the Securities Act to effectuate such “4(1) and half” transaction. 
 10. Payment of
Collection, Enforcement and Other Costs. If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding; or (b) an attorney is retained to represent the
Holder in any bankruptcy, reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company shall pay the costs incurred by the Holder for such
collection, enforcement or action, including reasonable attorneys’ fees and disbursements. 

  
 19. 

 11. Cancellation. After all Principal, Interest and other amounts at any time owed under,
or on account of, this Note have been paid in full or converted into Shares in accordance with the terms hereof, this Note shall automatically be deemed cancelled, shall be surrendered to the Company for cancellation and shall not be reissued. 

12. Registered Note. This Note may be transferred only upon notation of such transfer on the Register, and no assignment thereof shall
be effective until recorded therein. 
 13. Waiver of Notice. To the extent permitted by law, the Company hereby waives demand,
notice, presentment, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Facility Agreement. 

14. Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Note shall be governed
by and construed and enforced in accordance with the laws of the State of New York applicable to contracts made and to be performed in such State. All legal proceedings concerning the interpretations, enforcement and defense of the transactions
contemplated by this Note (whether brought against a party or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each
party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or
proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Note and agrees that such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. The parties hereby waive all rights to a trial by jury.

FORM OF OPINION 

            , 20         

[                    ] 

Re: KEMPHARM, INC. (the “Company”) 
 Dear Sir:

 [            ]
(“[            ]”) intends to transfer its Senior Secured Convertible Note in the principal amount of $            
(the “Note”) of the Company to              (“            ”) without registration under the Securities Act of
1933, as amended (the “Securities Act”). In connection herewith, we have examined such documents and issues of law as we have deemed relevant. 

Based on and subject to the foregoing, we are of the opinion that the transfer of the Note by
             to              may be effected without registration under the Securities Act, provided, however, that the Note to
be transferred to              contain a legend restricting its transferability pursuant to the Securities Act and that transfer of the Note is subject to a stop order. 

The foregoing opinion is furnished only to              and may not be used, circulated, quoted or
otherwise referred to or relied upon by you for any purposes other than the purpose for which furnished or by any other person for any purpose, without our prior written consent. 

Very truly yours,
