December 2019 Exchange Agreement and Amendment to Facility Agreement, Senior Secured Convertible Notes and Warrants

On December 17, 2019, KemPharm, Inc., a Delaware corporation (the “Company”), entered into a December 2019 Exchange Agreement and Amendment to Facility Agreement, Senior Secured Convertible Notes and Warrants (the “December 2019 Exchange Agreement”) with Deerfield Private Design Fund III, L.P., Deerfield Special Situations Fund, L.P. (together with Deerfield Private Design Fund III, L.P., the “Deerfield Lenders”) and Delaware Street Capital Master Fund, L.P. (“DSC” and, collectively with the Deerfield Lenders, the “Holders”). Under the Exchange Agreement, the Company is issuing senior secured convertible notes in the aggregate principal amount of $71,418,011.21 (the “December 2019 Notes”), in exchange for the cancellation of an aggregate of $71,418,011.21 principal amount and accrued interest of the Company’s 5.50% Senior Convertible Notes due 2021 (the “Indenture Notes”). Upon entering into the December 2019 Exchange Agreement, the Company agreed to pay the Holders, in the aggregate, an interest payment of $745,011.21, which represents 50% of the accrued interest, as of December 18, 2019, on the Indenture Notes owned by the Holders. The remainder of such interest will be included in the principal amount of the December 2019 Notes.

The December 2019 Notes bear interest at 6.75% per annum. The December 2019 Notes are convertible into shares of the Company’s common stock at an initial conversion price of $17.11 per share (which represents the conversion price of the Indenture Notes), subject to adjustment in accordance with the terms of the December 2019 Notes. As of the date of issuance, the December 2019 Notes are convertible, by their terms, into an aggregate of 4,174,051 shares of the Company’s common stock. The conversion price of the December 2019 Notes will be adjusted downward if the Company issues or sells any shares of common stock, convertible securities, warrants or options at a sale or exercise price per share less than the greater of the December 2019 Notes’ conversion price or the closing sale price of the Company’s common stock as reported on the Nasdaq Global Market on the last trading date immediately prior to such issuance, or, in the case of a firm commitment underwritten offering, on the date of execution of the underwriting agreement between the Company and the underwriters for such offering. However, if the Company effects an “at the market offering” as defined in Rule 415 of the Securities Act or 1933, as amended (the “Securities Act”), of its common stock, the conversion price of the December 2019 Notes will be adjusted downward pursuant to this anti-dilution adjustment only if such sales are made at a price less than $17.11 per share, provided that this anti-dilution adjustment will not apply to any sales made under (x) that certain Purchase Agreement, dated February 28, 2019, by and between the Company and Lincoln Park Capital Fund, LLC, (y) that certain Common Stock Sales Agreement, dated as of September 4, 2018, by and between the Company and RBC Capital Markets, LLC, or (z) that certain September 2019 Exchange Agreement and Amendment to Facility Agreement, dated as of September 3, 2019, by and among the Company, Deerfield Private Design Fund III, L.P. and Deerfield Special Situations Fund, L.P. (as amended). Notwithstanding anything in the contrary in the December 2019 Notes, the anti-dilution adjustment of such notes shall not result in the conversion price of the December 2019 Notes being less than $0.38 per share, representing the closing price of the Company’s common stock on the Nasdaq Global Market (as reflected on Nasdaq.com) on December 17, 2019. The December 2019 Notes are convertible at any time at the option of the holders thereof, provided that a holder of a December 2019 Note is prohibited from converting such note into shares of the Company’s common stock if, as a result of such conversion, such holder (together with certain affiliates and “group” members) would beneficially own more than 4.985% of the total number of shares of common stock then issued and outstanding. However, the December 2019 Note issued to DSC, due to the fact DSC was a beneficial owner of more than 4.985% of the total number of shares of the Company’s common stock then issued and outstanding, has a beneficial ownership cap equal to 19.985% of the total number of shares of the Company’s common stock then issued and outstanding. Pursuant to the December 2019 Notes, the Holders have the option to demand repayment of all outstanding principal, and any unpaid interest accrued thereon, in connection with a Major Transaction (as defined in the December 2019 Notes), which shall include, among others, any acquisition or other change of control of the Company; a liquidation, bankruptcy or other dissolution of the Company; or if at any time after March 31, 2021, shares of the Company’s common stock are not listed on an Eligible Market (as defined in the December 2019 Notes). The December 2019 Notes are subject to specified events of default, the occurrence of which would entitle the Holders to immediately demand repayment of all outstanding principal and accrued interest on the December 2019 Notes. Such events of default include, among others, failure to make any payment under the December 2019 Notes when due, failure to observe or perform any covenant under the Facility Agreement (as defined below) or the other transaction documents related thereto (subject to a standard cure period), the failure of the Company to be able to pay debts as they come due, the commencement of bankruptcy or insolvency proceedings against the Company, a material judgement levied against the Company and a material default by the Company under the Warrant, the December 2019 Notes or the Restated Note.

The December 2019 Exchange Agreement amends that certain Facility Agreement dated as of June 2, 2014, as amended (the “Facility Agreement”), by and between the Company and Deerfield Private Design Fund III, L.P, in order to, among other things, (i) provide for the Facility Agreement to govern the December 2019 Notes received by the Holders pursuant to the December 2019 Exchange Agreement, (ii) extend the maturity of the Senior Secured Convertible Notes (as defined in the Facility Agreement) from February 14, 2020 and June 1, 2020, as applicable, to March 31, 2021, (iii) defer interest payments on the Senior Secured Convertible Notes (as defined in the Facility Agreement) until March 31, 2021 (which such interest shall accrue as “payment-in-kind” interest), (iv) designate DSC as a Lender under (and as defined in the Facility Agreement), (v) name Deerfield Private Design Fund III, L.P. as the “Collateral Agent” for all Lenders and (vi) modify the terms and conditions under which the Company may issue additional pari passu and subordinated indebtedness under the Facility Agreement (subject to certain conditions specified in the Facility Agreement).

As a result of the transactions contemplated under the December 2019 Exchange Agreement, the Holders have agreed to defer any payments due (including all future accrued interest) under the Indenture Notes until March 31, 2021 and waived any put right under the Indenture Notes with regard to any delisting of the Company’s common stock until March 31, 2021.

The December 2019 Exchange Agreement also amends and restates that certain 6.75% senior secured note due 2020 that the Company previously issued to Deerfield Private Design Fund III, L.P. under the Facility Agreement (the “Restated Deerfield Note”) to conform the definitions of “Eligible Market” and “Major Transactions” to the definition in the December 2019 Notes, to remove provisions that were only applicable prior to the Company’s initial public offering and to make certain other changes to conform to the December 2019 Notes. The conversion price for the Restated Deerfield Note remains $5.85 per share, subject to adjustment on the same basis as the existing senior secured convertible notes, but subject to a floor price of $0.38.

The December 2019 Exchange Agreement also amends that certain warrant (the “Warrant”) previously issued to Deerfield Private Design Fund III, L.P. and exercisable for 1,923,077 shares of the Company’s common stock at an exercise price of $5.85 per share to conform the definitions of “Eligible Market” and “Major Transaction” in the Warrant with the definitions of such terms in the December 2019 Notes.

By entering into the Restated Deerfield Note and amending the terms of the Warrant, Deerfield Private Design Fund III, L.P. has waived such holder’s put right under the Restated Deerfield Note and the Warrant with regard to any delisting of the Company’s common stock until March 31, 2021.

The December 2019 Exchange Agreement contains customary representations, warranties and covenants made by the Company and the Holders, including a covenant of the Company to, upon request, use commercially reasonable efforts to use its technology to discover a product based upon a compound that may be identified by the Deerfield Lenders in a manner that is reasonably acceptable to the Deerfield Lenders, or one of their affiliates, with the terms of such discovery plan, including the Company’s compensation thereunder, to be mutually agreed to by the parties. The December 2019 Exchange Agreement also requires the Company to reimburse the Deerfield Lenders for up to $150,000 of expenses relating to the transactions contemplated by the December 2019 Exchange Agreement.

In connection with entering into the December 2019 Exchange Agreement, on December 18, 2019, the Company amended and restated that certain Guaranty and Security Agreement, dated June 2, 2014, by and between the Company and the other parties thereto (the “GSA”) to, among other things, (i) provide that all of the notes will be secured by the liens securing the indebtedness under the Facility Agreement, and (ii) name Deerfield Private Design Fund III, L.P. as the “Collateral Agent” under the GSA. The GSA also contains customary representations, warranties and covenants made by the Company.

The foregoing descriptions of the December 2019 Exchange Agreement, the December 2019 Notes, the Restated Deerfield Note and the GSA are a summary and are qualified in their entirety by Exhibits 10.1, 10.3, 10.4 and 10.5 attached hereto, each of which is incorporated by reference into this Item 1.01.

Amendment to September 2019 Exchange Agreement and Amendment to Facility Agreement

In connection with entering into the December 2019 Exchange Agreement, on December 17, 2019, the Company entered into an amendment (the “Amendment”) to that certain September 2019 Exchange Agreement and Amendment to Facility Agreement, dated as of September 3, 2019, by and among the Company and the Deerfield Lenders (the “September 2019 Exchange Agreement”) to, among other things, (i) amend and restate Annex I of the September 2019 Exchange Agreement to allow the Deerfield Lenders to effect optional exchanges of the December 2019 Notes and the Restated Deerfield Note under the terms of the September 2019 Exchange Agreement; (ii) amend the common stock exchange price under the September 2019 Exchange Agreement to be a per share price equal to the greater of (x) $0.60, subject to adjustment to reflect stock splits and similar events, or (y) the average of the volume-weighted average prices of the Company’s common stock on the Nasdaq Global Market on each of the 15 trading days immediately preceding such exchange, (iii) provide that no more than 28,439,015 of shares of the Company’s common stock shall be issued pursuant to optional exchanges under the September 2019 Exchange Agreement (whether by common stock exchange or upon conversion of Series B-2 Shares (as defined in the Amendment)), subject to adjustment to reflect stock splits and similar events and (iv) eliminate limitations regarding the timing and aggregate amount of principal which may be exchanged under the September 2019 Exchange Agreement. The Amendment also contains customary representations, warranties and covenants made by the Company.

(“DPDF”), Deerfield Special Situations Fund, L.P. (“DSS” and, together with DPDF, the “Deerfield Lenders”), Delaware Street Capital Master Fund, L.P. (“DSCM” and, together with the Deerfield Lenders, the “Lenders”). Capitalized terms used but not otherwise defined in this Agreement shall have the meanings given to them in the Facility Agreement (as defined below).

RECITALS:

A. The Lenders own an aggregate of $70,673,000 principal amount of the Borrower’s 5.50% Senior Convertible Notes due 2021 (the “Indenture Notes”) issued pursuant to the Indenture, dated as of February 9, 2016 (the “Indenture”), between the Borrower and U.S. Bank National Association, as trustee under the Indenture (together with any successor thereto, the “Trustee”).

B. The Borrower and DPDF have entered into that certain Facility Agreement, dated as of June 2, 2014 (as the same previously has been amended, modified, restated or otherwise supplemented from time to time, the “Existing Facility Agreement”). Upon the execution and delivery of the Existing Facility Agreement, DPDF disbursed the First Disbursement (as defined in the Existing Facility Agreement), which (i) included (among other loans) a term loan of $10,000,000, which is evidenced by the Senior Secured Convertible Note (as defined in the Existing Facility Agreement) (the “Existing FA Note”); and (ii) obligated the Borrower to issue the Warrant (as defined in the Existing Facility Agreement).

C. Prior to the date hereof, the Borrower has satisfied a portion of the principal amount under the Existing FA Note, leaving $6,980,824.22 in principal amount of the Existing FA Note outstanding.

D. The Existing Facility Agreement obligates the Borrower to pay to DPDF $3,333,333.33 of the outstanding principal amount of the Existing FA Note, including the applicable PIK Increase Amount, on February 14, 2020 (the “February 2020 Payment”) and the balance of the outstanding principal amount of the Existing FA Note, together with all accrued and unpaid interest on the Existing FA Note, on June 1, 2020 (the “Final Payment”).

E. Pursuant to this Agreement (and subject to the terms and conditions hereof), the Lenders will exchange all of the Indenture Notes for Senior Secured Convertible Notes of the Borrower in substantially the form attached hereto as Exhibit A (the “December 2019 Notes”) in an aggregate principal amount equal to the sum of the outstanding principal amount of all of the Indenture Notes, plus 50% of the accrued and unpaid interest thereon through the Effective Date. The December 2019 Notes will be issued pursuant to the Facility Agreement (as defined below).

F. Subject to the terms and conditions of this Agreement, DPDF has agreed with the Borrower to (y) amend the Existing Facility Agreement and the Warrants, among other things, (i) to defer the February 2020 Payment and the Final Payment until, and to provide for payment of principal and interest on the Existing FA Note on, March 31, 2021, (ii) to modify the definition of “Permitted Indebtedness” to permit the Borrower to incur additional Indebtedness as set forth herein, and (iii) to make such other changes as may be necessary or appropriate to provide for the exchange of Indenture Notes for December 2019 Notes as provided herein and (z) amend and restate the Existing FA Note to be in substantially the form attached hereto as Exhibit B (as so amended and restated, the “A&R Senior Secured Convertible Note” and, together with the December 2019 Notes, the “Notes”). The Existing Facility Agreement, as amended hereby and as the same may in the future be amended, modified, restated or otherwise supplemented from time to time is referred to herein as the “Facility Agreement.”

G. Subject to the terms and conditions of this Agreement, the Lenders have agreed with the Borrower to, among other things, (i) allow the “payment in kind” of interest on the indebtedness currently evidenced by the Indenture Notes, (ii) defer the maturity date in respect of the indebtedness evidenced by the Indenture Notes to March 31, 2021, and (iii) modify certain rights of the Lenders under the Indenture Notes that would result from a delisting of the Borrower’s Common Stock, all to be effected through the Exchange (as defined below) and the amendments to the Existing Facility Agreement contemplated hereby.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

(f) Issuance of Conversion Shares. The Conversion Shares issuable upon conversion of the Notes are duly authorized and, when issued in accordance with the applicable Note, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens imposed by the Borrower, and will not be issued in violation of, or subject to, any preemptive or

8

similar rights of any person. The Borrower has reserved from its duly authorized capital stock an aggregate of 5,384,788 shares of Common Stock for issuance hereafter upon conversion of the Notes in accordance with the terms thereof (plus any additional shares of Common Stock that may be issuable as a result of the anti-dilution provisions of the Notes), in each case, free and clear of preemptive or similar rights.

The Borrower has filed all reports, schedules, forms, statements and other documents required to be filed by it under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the date hereof (the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, being collectively referred to herein as the “SEC Reports”). None of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Except as set forth in the Borrower’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2019, as filed with the Commission on November 14, 2019, and the Borrower’s Current Reports on Form 8-K filed with the Commission on May 23, 2019, October 3, 2019 and November 21, 2019 (such disclosure the “Potential Delisting”), the Borrower is not in violation of the requirements of the Nasdaq Global Market (“Nasdaq GM”) and has no knowledge of any facts or circumstances which could reasonably lead to delisting or suspension of trading of the Common Stock in the foreseeable future.

(h) Certain Fees. No brokerage or finder’s fees or commissions are or will be payable by the Borrower or any of its affiliates or representatives to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement. The Lenders shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section 3.02(h) that may be due in connection with the transactions contemplated hereby.

(i) Exemption from Registration. No registration under the Securities Act or any state securities laws is or will be required for the offer and issuance of the December 2019 Notes by the Borrower to the Lenders as contemplated hereby or for the offer and issuance of the Conversion Shares by the Borrower to the Lenders as contemplated hereby and by the Notes. The amendments and transactions contemplated hereby or entered into in connection herewith, including the issuance and sale of the December 2019 Notes hereunder and the issuance and sale of the Conversion Shares pursuant to the terms of the Notes do not and will not contravene, or require stockholder approval pursuant to, the rules and regulations of The Nasdaq Stock Market LLC, as currently in effect. Assuming each Lender to which December 2019 Notes or Conversion Shares are to be issued is not as of the date of issuance, and for a period of three (3) months prior to the date of issuance has not been, an “affiliate” (as such term is used in Rule 144 under the Securities Act) of the Borrower (which the Borrower shall assume (and the applicable Lender shall be deemed to represent) unless such Lender has otherwise advised the Borrower in writing) and in reliance on such Lender’s representations contained in Section 3.01(e) hereof, the Notes and the Conversion Shares, other than those issued to DSCM, will be freely tradeable by such Lender without restriction or limitation (including volume limitation), pursuant to Rule 144 under the

9

Securities Act, and will not contain or be subject to any legend or stop transfer instructions restricting the sale or transferability thereof. The Borrower has not paid or given (and will not pay or give), directly or indirectly, any commission or other remuneration for soliciting the exchange to be effected pursuant to this Agreement or otherwise in connection with the issuance and sale of any December 2019 Notes or any Conversion Shares pursuant to this Agreement or the December 2019 Notes. The Borrower is not, and never has been, a “shell company” (as defined in Rule 12b-2 under the Exchange Act) and is not an issuer of a type identified in, or subject to, Rule 144(i)(1) under the Securities Act.

(j) No Integrated Offering. Neither the Borrower, nor any of its affiliates, nor any person acting on its or their behalf has, directly or indirectly, made, or will make, any offers or sales of any security or solicited, or will solicit, any offers to buy any security, under circumstances that would cause the offering and issuance of the December 2019 Notes or the offering and issuance of any of the Conversion Shares to be integrated with prior or contemporaneous offerings by the Borrower (i) for purposes of the Securities Act and which would require the registration of any such securities under the Securities Act, or (ii) for purposes of any applicable stockholder approval provisions of the Nasdaq GM and which would require stockholder approval for the issuance of any December 2019 Notes or Conversion Shares.

(k) No Bad Actor Disqualification. None of the Credit Parties, any of its predecessors, any director, executive officer, other officer of any Credit Party participating in the offering of the Notes or the Conversion Shares, any beneficial owner (as that term is defined in Rule 13d-3 under the Exchange Act) of 20% or more of any Credit Party’s outstanding voting equity securities, calculated on the basis of voting power, any “promoter” (as that term is defined in Rule 405 under the Securities Act) connected with any Credit Party at the time this representation is made, any placement agent or dealer participating in the offering of the Notes or the Conversion Shares and any of such agents’ or dealer’s directors, executive officers, other officers participating in the offering of the Notes or the Conversion Shares (each, a “Covered Person”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (a “Disqualification Event”). The Borrower has exercised reasonable care to determine (i) the identity of each person that is a Covered Person and (ii) whether any Covered Person is subject to a Disqualification Event. Each Credit Party has complied in all material respects, to the extent applicable, with its disclosure obligations under Rule 506(e). No Credit Party is any other reason disqualified from reliance upon Rule 506 of Regulation D for purposes of the offer, sale and issuance of the Notes or the Conversion Shares.

(l) No Unlawful Payments. Neither the Borrower, to the knowledge of the Borrower, nor any of its directors or officers or any employee, agent, affiliate, representative of or other person associated with or acting on behalf of the Borrower, has (a) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity, (b) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds, (c) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or (d) made any bribe, unlawful rebate, payoff, influence payment, kickback or other unlawful payment.

10

(m) Compliance with Money Laundering Laws. The operations of the Borrower are and have been conducted at all times in compliance with all financial recordkeeping and reporting requirements applicable to the Borrower, including those of the Bank Secrecy Act, as amended by Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT) Act of 2001, and the money laundering and any related or similar laws of all jurisdictions in which the Borrower conducts business (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any governmental authority involving the Borrower with respect to the Money Laundering Laws is pending or, to the knowledge of the Borrower, threatened.

(o) Application of Takeover Protections. The Borrower and its board of directors have taken all necessary action, if any, in order to render inapplicable the Borrower’s issuance of the Notes and Conversion Shares and the Lenders’ ownership of such securities from the provisions of any control share acquisition, interested stockholder, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the organizational documents of the Borrower or the laws of the state of its incorporation which is applicable to the Lenders as a result of the transactions contemplated by this Agreement, including the Borrower’s issuance of the December 2019 Notes and Conversion Shares and the Lenders’ ownership of such securities and the A&R Senior Secured Convertible Note.

(p) Cash on Hand. The Borrower believes as of the Effective Date, after giving effect to the transactions contemplated under this Agreement, that its existing balances of cash and cash equivalents will be sufficient to finance its anticipated working capital and operating expense requirements for the period commencing on the date hereof and ending on March 31, 2021, which the Borrower shall disclose in the Announcing 8-K Filing.

(q) Litigation. No proceeding is pending before or, to the knowledge of Borrower, threatened by any Governmental Authority (a) to which any Credit Party is a party, (b) that purports to affect or pertain to the Transaction Documents or the transactions contemplated hereby or thereby or (c) that has as the subject thereof any assets owned by any Credit Party or any of its Subsidiaries, in each case, that could reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect. No injunction, writ, temporary restraining order or any order of any nature has been issued by any court or other Governmental Authority purporting to enjoin or restrain the execution, delivery or performance of this Agreement or any other Transaction Document or directing that the transactions provided for herein or therein not be consummated as herein or therein provided.

(r) Compliance with Laws. Except as could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect, each Credit Party is in compliance with all Applicable Laws and authorizations.

Section 7.05. Applicable Law; Consent to Jurisdiction.

(a) As part of the consideration and mutual promises being exchanged and given in connection with this Agreement, the parties hereto agree that all claims, controversies and disputes of any kind or nature arising under or relating in any way to the enforcement or interpretation of this Agreement or to the parties’ dealings, rights or obligations in connection herewith, including disputes relating to the negotiations for, inducements to enter into, or execution of, this Agreement, and disputes concerning the interpretation, enforceability, performance, breach, termination or validity of all or any portion of this Agreement shall be governed by the laws of the State of New York without giving effect to any laws, rules or provisions that would cause the application of the laws of any jurisdiction other than the State of New York.

(b) The parties hereto agree that all claims, controversies and disputes of any kind or nature relating in any way to the enforcement or interpretation of this Agreement or to the parties’ dealings, rights or obligations in connection herewith, shall be brought exclusively in the state and federal courts sitting in The City of New York, borough of Manhattan. With respect to any such claims, controversies or disputes, each of the parties hereby irrevocably:

(i) submits itself and its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action in any court or tribunal other than the aforesaid courts;

(ii) waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding (A) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 7.05, (B) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (C) to the fullest extent permitted by the applicable law, any claim that (1) the suit, action or proceeding in such court is brought in an inconvenient forum, (2) the venue of such suit, action or proceeding is improper or (3) this Agreement, or the subject matter hereof, may not be enforced in or by such courts; and

17

(iii) WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY DISPUTE ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.05.

Notwithstanding the foregoing in this Section 7.05, a party may commence any action or proceeding in a court other than the above-named courts solely for the purpose of enforcing an order or judgment issued by one of the above-named courts.

Section 7.06. Counterparts; Effectiveness. This Agreement and any amendment hereto may be executed and delivered in any number of counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. In the event that any signature to this Agreement or any amendment hereto is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. No party hereto shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that such signature was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation or enforceability of a contract, and each party hereto forever waives any such defense.

Section 7.07. No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person (other than the parties to this Agreement) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 7.08. Remedies; Specific Performance. The rights and remedies provided in this Agreement shall be cumulative and in addition to all other remedies available under the Facility Agreement, the A&R Senior Secured Convertible Note, the December 2019 Notes, the other Transaction Documents and/or otherwise at law or in equity. No remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy, and nothing herein shall limit any Lender’s right to pursue actual damages for any failure by the Borrower to comply with the terms of this Agreement, the Facility Agreement, the A&R Senior Secured Convertible Note, the December 2019 Notes and the other Transaction Documents. The parties to this Agreement agree that irreparable damage would occur and that the parties to this Agreement would not have any adequate remedy at law in the event that any of the provisions of this Agreement, the Facility Agreement or any other Transaction Document were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each of the parties to this Agreement shall be entitled to an injunction or injunctions to prevent breaches of this Agreement, the Facility Agreement or any other Transaction Document and to enforce specifically the terms and provisions of this Agreement, the Facility Agreement, and the other Transaction Documents in each case without the necessity of posting bond or other security or showing actual damages, and this being in addition to any other remedy to which such party is entitled at law or in equity.

18

Section 7.09. Effect of Headings. The section and subsection headings herein are for convenience only and not part of this Agreement and shall not affect the interpretation thereof.

Section 7.10. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

Section 7.11. Reservation of Rights. None of the Lenders has hereby waived any of such Lender’s rights or remedies arising from any breach or default or any right otherwise available under the Facility Agreement, any other Transaction Document or at law or in equity as to any of such Lender’s Notes. Each of the Lenders expressly reserves all such rights and remedies. Notwithstanding anything else to the contrary herein, each Lender hereby agrees that the issuance of the December 2019 Notes to such Lender satisfies in full any and all obligations of the Borrower under the Indenture as to the Indenture Notes held by such Lender and such Lender’s remedies with regard to such Indenture Notes shall be solely as described in this Agreement.

Section 7.12. Further Assurances. The parties hereby agree, from time to time, as and when reasonably requested by any other party hereto, to execute and deliver or cause to be executed and delivered, all such documents, instruments and agreements, including secretary’s certificates, stock powers and irrevocable transfer agent instructions, and to take or cause to be taken such further or other action, as any party may reasonably deem necessary or desirable in order to carry out the intent and purposes of this Agreement. Without limiting the foregoing, the Borrower shall take such action, and deliver such notices, documents, instruments and agreements as the Trustee may reasonably require to effectuate the exchange and surrender of Indenture Notes in accordance with this Agreement.

Section 7.13. No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party.

19

Section 7.14. Interpretative Matters. Unless otherwise indicated or the context otherwise requires, (a) all references to Sections, Schedules, Appendices or Exhibits are to Sections, Schedules, Appendices or Exhibits contained in or attached to this Agreement, (b) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter, (c) the words “hereof,” “herein” and words of similar effect shall reference this Agreement in its entirety, and (d) the use of the word “including” in this Agreement shall be by way of example rather than limitation. Unless otherwise indicated, references to “Transaction Documents” in this Agreement refer to Transaction Documents (as defined in the Facility Agreement), each as amended as of the Effective Date, including as provided by this Agreement. For the avoidance of doubt, any difference in the provisions of the form of December 2019 Notes from the form of note representing the Existing FA Note should not be interpreted in any manner adverse to the interests of the holder of the Existing FA Note.

Section 7.15. Reaffirmation. Other than as expressly provided in this Agreement, the execution and delivery of this Agreement shall not operate as a waiver of any right, power or remedy of the Lenders, constitute a waiver of any provision of the Facility Agreement, the Existing FA Note, any other Transaction Documents (as currently in effect) or any other document executed in connection therewith or serve to effect a novation of the obligations thereunder. The Borrower, as issuer, debtor, grantor, pledger, mortgagor, guarantor or assignor, or in other any other similar capacity in which it grants liens or security interests in its property hereby (i) acknowledges and agrees that it has reviewed this Agreement, (ii) ratifies and reaffirms all of its obligations, contingent or otherwise, under each of the Transaction Documents, and (iii) to the extent the Borrower granted Liens on or security interests in any of its property pursuant to any such Transaction Document as security for the Obligations (as defined in the Facility Agreement) under or with respect to the Transaction Documents, ratifies and reaffirms such grant of security interests and Liens as provided in the Transaction Documents and confirms and agrees that such security interests and Liens continue to secure all of the currently outstanding or future Obligations (as amended hereby) on the terms and conditions of the Transactions Documents (for the avoidance of doubt as amended as of the date of this Agreement (including as provided in this Agreement)). The Borrower hereby consents to this Agreement and acknowledges that this Agreement, each December 2019 Note, the A&R Senior Secured Convertible Note and each document or agreement executed and delivered pursuant to, or in connection with, the execution and delivery of this Agreement is a Transaction Document and each of the other Transaction Documents, each as amended as of the Effective Date (including as provided in this Agreement), remains in full force and effect and is hereby ratified and reaffirmed; provided that, nothing in this Section 7.15 shall obligate the Borrower to restate, or be considered to be a restatement of, the representations of the Borrower contained in Article 3 of the Facility Agreement as of the date hereof. Any reference in the Transaction Documents to “hereunder,” “hereof,” “herein,” or words of like import referring to such agreement shall refer to such Transaction Document as amended as of the Effective Date (including as provided in this Agreement). For the avoidance of doubt, the parties acknowledge and agree that, nothing contained herein or in Exhibit C shall be deemed or construed as an agreement by any Lender to make any Disbursement or additional Loan on or after the date hereof.

Section 7.16. Payment Set Aside. Notwithstanding anything to the contrary contained herein, if any payment or transfer (or any portion thereof) to either of the Lenders shall be subsequently invalidated, declared to be fraudulent or a fraudulent conveyance or preferential, avoided, rescinded, set aside or otherwise required to be return or repaid, whether in bankruptcy, reorganization, insolvency or similar proceedings involving the Borrower or otherwise, then the Obligations (as defined in the Facility Agreement) purportedly satisfied with such payment or

20

transfer, to the extent that such payment is or must be invalidated, declared to be fraudulent or a fraudulent conveyance or preferential, avoided, rescinded, set aside or otherwise required to be return or repaid, shall immediately be reinstated, without need for any action by any Person, and shall be enforceable against the Borrower, any guarantor and their successors and permitted assigns as if such payment had never been made (in which case this Agreement shall in no way impair the claims of Lenders with respect to such payment or transfer). The provisions of this Section 7.16 shall survive the satisfaction in full of the Obligations and the termination of the Facility Agreement.

Section 7.17. Termination. Except to the extent otherwise agreed in writing by the Lenders prior to the Effective Time, this Agreement shall terminate and be of no further force or effect if any of the conditions set forth in Article VI are not satisfied or waived by the Required Lenders on or prior to December 18, 2019; provided, however, that the Borrower’s obligations under Section 4.06 hereof shall survive such termination until performed by the Borrower in full.

Section 7.18. Independent Nature of Lenders. The obligations of each Lender under this Agreement and each of the other Transaction Documents are several and not joint with the obligations of any other Lender, and no Lender shall be responsible in any way for the performance of the obligations of any other Lender under this Agreement or any other Transaction Document. Each Lender shall be responsible only for its own representations, warranties, agreements and covenants hereunder and under the other Transaction Documents. The decision of each Lender to enter into this Agreement, consummate the Exchange and acquire the December 2019 Notes pursuant to this Agreement has been made by such Lender independently of any other Lender and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Borrower that may have been made or given by any other Lender or by any agent, attorney, advisor, representative or employee of any other Lender, and no Lender or any of its agents, attorneys, advisors, representatives or employees shall have any liability to any other Lender (or any other Person) relating to or arising from any such information, materials, statements or opinions. Nothing contained in this Agreement, and no action taken by any Lender pursuant hereto or thereto (including a Lender’s acquisition of Obligations, Notes, Conversion Shares or any other securities at the same time as any other Lender), shall be deemed to constitute the Lenders as, and the Borrower acknowledges and agrees that the Lenders do not thereby constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Lenders are in any way acting in concert or as a group with respect to such Obligations or the transactions contemplated by this Agreement or any other Transaction Document, and the Borrower shall not assert any contrary position.

Section 7.19. No Fiduciary Relationship. The Borrower acknowledges and agrees that (a) each Lender is acting at arm’s length from the Borrower with respect to this Agreement and the Transaction Documents and the transactions contemplated hereby and thereby; (b) no Lender will, solely by virtue of this Agreement or any of the Transaction Documents or any transaction contemplated hereby or thereby, become an Affiliate of, or have any agency, tenancy or joint venture relationship with, the Borrower (provided that this clause (b) shall not apply to any Lender that on the Effective Date receives a December 2019 Note with a 19.985% Cap); (c) no Lender has acted, or is or will be acting, as a financial advisor to, or fiduciary (or in any similar capacity) of, or has any fiduciary or similar duty to, the Borrower with respect to, or in connection with, this

21

Agreement and the Transaction Documents and the transactions contemplated hereby and thereby, and the Borrower agrees not to assert, and hereby waives, any claim that any Lender has any fiduciary duty to the Borrower; (d) any advice given by a Lender or any of its representatives or agents in connection with this Agreement and the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such Lender’s performance of its obligations hereunder and thereunder (including, in the case of each of the Lenders, its acquisition of the December 2019 Notes and any Conversion Shares); and (e) the Borrower’s decision to enter into this Agreement has been based solely on the independent evaluation by the Borrower and their representatives.

22

IN WITNESS WHEREOF, each party hereto has caused this Agreement to be duly executed as of the date first written above.

Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.5(d)(i), (ii), (iii) and Section 2.5(f) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Without limiting the generality of the foregoing, each Lender, on or prior to the date of becoming a Lender hereunder (and in each case, from time to time thereafter upon the reasonable request of Borrower) will deliver to Borrower either:

(i) a duly completed IRS Form W-9 (or successor form) certifying that the Lender is a U.S. person for U.S. tax purposes and is exempt from U.S. federal backup withholding tax (provided, however, that if the Lender is a disregarded entity for U.S. federal income tax purposes it shall provide a properly completed and executed IRS Form W-9 for its non-disregarded owner in the appropriate manner); or

(ii) if it is not a U.S. person for U.S. federal income tax purposes and is legally entitled to do so, a properly completed and executed IRS Form W-8ECI, W-8BEN, W-8BEN-E, W-8IMY or other applicable form (together with any required supporting documentation), or any other applicable certificate or document reasonably requested by the Borrower, certifying in the case of an IRS Form W-8BEN, W-8BEN-E or W-8ECI the extent to which such Lender is entitled to receive payments under this Agreement at a reduced rate of, or exemption from, deduction or withholding of any U.S. withholding tax and, if such Lender is relying on the portfolio interest exception of Section 871(h) or Section 881(c) of the Code (or any successor provision thereto), shall also provide the Borrower with a certificate (the “Portfolio Interest Certificate”) representing that such Lender is not

18

a “bank” for purposes of Section 881(c) of the Code (or any successor provision thereto), is not a 10% shareholder of the Borrower described in Section 871(h)(3)(B) of the Code (or any successor provision thereto), and is not a controlled foreign corporation receiving interest from a related person (within the meaning of Sections 881(c)(3)(C) and 864(d)(4) of the Code, or any successor provisions thereto); and

(iii) each Lender that delivers to Borrower an IRS Form W-9, W-8BEN, W-8BEN-E, W-8ECI, or W-8IMY or other document pursuant to this Section 2.5(d) further undertakes to deliver to Borrower further copies of the said form or other document and IRS Form W-8BEN, W-8BEN-E, W-8ECI, W-8IMY or successor applicable forms, or other manner of certification, as the case may be within a reasonable time after gaining knowledge of the occurrence of any event requiring a change in the most recent forms or other documents previously delivered by it to Borrower, and such extensions or renewals thereof as may reasonably be requested by Borrower.

(e) If a Lender determines in good faith that it has received a refund from a Governmental Authority of Taxes in respect of which the Borrower paid Additional Amounts or made a payment pursuant to this Section 2.5, such Lender shall promptly pay such refund (limited to the amount of indemnity payments including Additional Amounts made by Borrower under this Section 2.5 with respect to the Taxes refunded) to the Borrower, net of all out-of-pocket expense (including any Taxes imposed thereon) of such Lender incurred in obtaining such refund, provided that the Borrower, upon the request of such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Lender if such Lender is required to repay such refund to such Governmental Authority and provides written evidence thereof to the Borrower. Nothing in this Section shall require any Lender to disclose any information it deems confidential (including, without limitation, its Tax returns) to any Person, including Borrower.

(f) If a payment made to a Lender under any Transaction Document would be subject to withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), then such Lender shall deliver to the Borrower at the time or times prescribed by law and at such time or times reasonably requested by the Borrower such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower as may be necessary for the Borrower to comply with its obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. For purposes of determining withholding Taxes imposed under FATCA, from and after the Effective Date, the Borrower shall treat (and the Lenders hereby authorize the Borrower to treat) the Loans as not qualifying as grandfathered obligations within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i). Solely for purposes of this Section 2.5(f), “FACTA” shall include any amendments made to FATCA after the Agreement Date.

19

(g) If the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or Governmental Authority for the account of any Lender pursuant to any of Section 2.5(a) through Section 2.5(c), then such Lender shall at the request of the Borrower use commercially reasonable efforts to mitigate the effect of any such event by completing and delivering or filing any Tax-related forms or other documents that the Lender is lawfully able to deliver and that would establish the Lender’s eligibility for a reduction or elimination of any amount of Taxes required to be deducted or withheld or paid by the Borrower hereunder, unless the Lender determines that such completion, delivery or filing of such forms or other documents (other than such documentation set forth in paragraphs (d)(i), (d)(ii), (d)(iii) and (f) of this Section 2.5) would subject such Lender to any significant unreimbursed cost or loss or would prejudice the legal, commercial or tax position of such Lender.

(h) For purposes of this Section 2.5, the term “Applicable Law” includes FATCA.

Section 2.6 Costs, Expenses and Losses(a) . If, as a result of any failure by the Borrower to pay any sums due under this Agreement on the due date therefor (after the expiration of any applicable grace periods), the Lenders shall incur costs, expenses and/or losses, by reason of the liquidation or redeployment of deposits from third parties or in connection with obtaining funds to make a Disbursement, the Borrower shall pay to any Lender upon request by such Lender, the amount of such costs, expenses and/or losses within 15 Business Days after receipt by it of a certificate from such Lender setting forth in reasonable detail such costs, expenses and/or losses, along with supporting documentation. For the purposes of the preceding sentence, “costs, expenses and/or losses” shall include, without limitation, any interest paid or payable to carry any unpaid amount and any loss, premium, penalty or expense which may be incurred in obtaining, liquidating or employing deposits of or borrowings from third parties in order to make, maintain or fund the Loan or any portion thereof.

Section 2.7 Interest.

The outstanding principal amount of the Notes shall bear interest at the Interest Rate (calculated on the basis of the actual number of days elapsed in each month). Except as set forth in Section 2.3(d), accrued interest shall first be paid in arrears on July 1, 2014 and thereafter quarterly in arrears on the first Business Day of each, October, January, April and July thereafter (each, an “Interest Payment Date”). From and after the Effective Date, interest shall be paid in accordance with Section 2.3(d).

Section 2.8 Interest on Late Payments. Without limiting the remedies available to the Lenders under the Transaction Documents or otherwise, to the maximum extent permitted by Applicable Laws, if the Borrower fails to make a required payment of principal or interest with respect to the Notes when due, the Borrower shall pay on demand by the Required Lenders, in respect of such unpaid principal and interest, interest at the rate per annum equal to the Interest Rate plus 10% for so long as such payment remains outstanding.

Section 2.9 Intentionally Deleted.

(b) Upon the DPDF Lender effecting the Second Disbursement the Borrower shall issue to the DPDF Lender warrants to purchase an aggregate of 9,615,385 “Warrant Shares” (as defined in the Warrants) in substantially the form set forth on Exhibit E hereto at an initial Exercise Price of $0.78 and an expiration date that is on the ten (10) year anniversary of the date of the Second Disbursement.

(d) Notwithstanding anything herein to the contrary, the number of Warrant Shares into which the Warrants to be issued pursuant to Section 2.10(b) and (c) are exercisable and the Subsequent Warrant Exercise Price thereof on the issue date shall be adjusted to reflect any adjustments in the number of Warrant Shares into which such Warrant is exercisable that would have taken effect pursuant to the terms of such Warrant had such Warrant been issued on the Closing Date and remained outstanding through the date of such issuance.

(e) “Subsequent Warrant Exercise Price” means an amount equal to (i) prior to an IPO, (x) $75,000,000, divided by (y) the number of shares of Common Stock then outstanding (on a fully-diluted basis assuming the exercise of all outstanding options and warrants, the conversion of all convertible securities and the conversion of all shares of capital stock of the Borrower into shares of Common Stock) and (ii) from an after the consummation of an IPO, 115% of the Volume Weighted Average Prices for the Borrower’s Common Stock for the twenty (20) consecutive Trading Day period prior to the date of the Third Disbursement or the Fourth Disbursement, as the case may be.

(collectively, the “OTC Market”). If the Volume Weighted Average Price cannot be calculated for such security on such date in the manner provided above, the volume weighted average price shall be the fair market value as mutually determined by the Borrower and the Required Lenders.

21

“Trading Day” means any day on which the Common Stock is traded for at least two hours on the principal securities exchange, trading market or quotation system on which the shares of Common Stock are then traded, quoted or listed.

Section 6.4 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement 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.

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.

This Agreement shall bind and inure to the respective successors and permitted assigns of the Parties, except that the Borrower may not assign or otherwise transfer all or any part of its rights under the Transaction Documents without the prior written consent of the Lenders.

No amendment, restatement, modification, supplement, change, termination or waiver of any provision of this Agreement or the other Transaction Documents (other than the Warrants, any Control Agreement or any similar agreement or any landlord agreement or bailee or mortgagee waiver, each of which may be amended, restated, supplemented, changed, terminated or waived in accordance with the terms thereof), and no consent to any departure by the Borrower or any other Credit Party therefrom shall in any event be effective without the written concurrence of the Borrower and the Required Lenders (and shall not require the consent of any other Lenders). Nothing contained in this Section 6.6 shall prohibit, restrict or limit or be deemed to prohibit, restrict or limit, the entry by any Credit Party into separate agreements and/or transactions with any Lender or Affiliate thereof, in respect of the Notes held by such Lender or otherwise, to the extent not otherwise prohibited, restricted or limited by this Agreement or any of the Transaction Documents.

Section 6.7 Severability. If any provision of this Agreement shall be invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. The Parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provision.

Section 6.8 Execution; Counterparts. This Agreement may be executed in several Counterparts and by each Party by facsimile or other electronic transmission (including by email with an attached digital representation of a signature page hereto) on separate counterparts, each of which and any facsimile or other electronic copies thereof shall be deemed an original, but all of which together shall constitute one and the same agreement.

Section 6.9 Survival.

(a) This Agreement and all agreements, representations and warranties made in the Transaction Documents, and in any document, certificate or statement delivered pursuant thereto or in connection therewith shall be considered to have been relied upon by the other Parties and shall survive the execution and delivery of this Agreement and the making of the Loan hereunder regardless of any investigation made by any such other Party or on its behalf, and shall continue in force until all amounts payable under the Transaction Documents shall have been fully paid in accordance with the provisions thereof, and the Lenders shall not be deemed to have waived, by reason of making the Loan, any Event of Default that may arise by reason of such representation or warranty proving to have been false or misleading, notwithstanding that the Lenders may have had notice or knowledge of any such Event of Default or may have had notice or knowledge that such representation or warranty was false or misleading at the time the Disbursement was made.

(b) The obligations of the Borrower under Sections 1.4 and 2.5 and the obligations of the Borrower and the Lenders under this Article 6, including, without limitation, Section 6.11 and 6.17, shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, or the termination of this Agreement or any provision hereof.

Section 6.10 Waiver. Neither the failure of, nor any delay on the part of, any Party in exercising any right, power or privilege hereunder, or under any agreement, document or instrument mentioned herein, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder, or under any agreement, document or instrument mentioned herein, preclude other or further exercise thereof or the exercise of any other right, power or privilege; nor shall any waiver of any right, power, privilege or default hereunder, or under any agreement, document or instrument mentioned herein, constitute a waiver of any other right, power, privilege or default or constitute a waiver of any default of the same or of any other term or provision. No course of dealing and no delay in exercising, or omission to exercise, any right, power or remedy accruing to the Lenders upon any default under this Agreement or any other agreement shall impair any such right, power or remedy or be construed to be a waiver thereof or an acquiescence therein; nor shall the action of the Lenders in respect of any such default, or any acquiescence by it therein, affect or impair any right, power or remedy of the Lenders in respect of any other default. All rights and remedies herein provided are cumulative and not exclusive of any rights or remedies otherwise provided by law.

Section 6.11 Indemnity.

(a) The Borrower shall, at all times, indemnify and hold each Lender harmless (the “Indemnity”) and each of their respective directors, partners, officers, employees, agents, counsel and advisors (each, an “Indemnified Person”) in connection with any losses, claims (including the reasonable and documented out-of-pocket attorneys’ fees incurred in defending against such claims), damages, liabilities, penalties, or other reasonable and documented out-of-

42

pocket expenses arising out of, or relating to, the Transaction Documents, the extension of credit hereunder, the Loan or the use or intended use of the Loan, or a breach of Section 3.1(h) of this Agreement, regardless of Borrower’s lack of knowledge, which an Indemnified Person may incur or to which an Indemnified Person may become subject but (each, a “Loss”). The Indemnity shall not apply (i) to the extent that a court or arbitral tribunal of competent jurisdiction issues a final judgment that such Loss resulted from the gross negligence or willful misconduct of the Indemnified Person or (ii) to Losses that do not involve an act or omission by the Borrower or any of its Affiliates and that is brought by an Indemnified Person against any other Indemnified Person or (iii) in relation to any settlement effected by any Indemnified Person without the Borrower’s consent. The Indemnity is independent of and in addition to any other agreement of the Borrower under any Transaction Document to pay any amount to the Lenders, and any exclusion of any obligation to pay any amount under this subsection shall not affect the requirement to pay such amount under any other section hereof or under any other agreement. For the avoidance on doubt, this Section 6.11 shall not apply to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(b) Promptly after receipt by an Indemnified Person under this Section 6.11 of notice of the commencement of any action (including any governmental action), such Indemnified Person shall, if a Loss in respect thereof is to be made against the indemnifying person under this Section 6.11, deliver to Borrower a written notice of the commencement thereof, and Borrower shall have the right to participate in, and, to the extent Borrower so desires, to assume control of the defense thereof with counsel mutually satisfactory to Borrower and the Indemnified Person, as the case may be.

(c) An Indemnified Person shall have the right to retain its own counsel with the reasonable and documented out-of-pocket fees and expenses to be paid by the indemnifying person, if, in the reasonable opinion of counsel for the Indemnified Person, the representation by such counsel of the Indemnified Person and Borrower would be inappropriate due to actual or potential differing interests between such Indemnified Person and any other party represented by such counsel in such proceeding. The Borrower shall pay for only one separate legal counsel for the Indemnified Persons. The failure of an Indemnified Person to deliver written notice to the Borrower within a reasonable time of the commencement of any such action shall not relieve the Borrower of any liability to the Indemnified person under this Section 6.11, except to the extent that Borrower is actually prejudiced in its ability to defend such action. The indemnification required by this Section 6.11 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable.

(d) The Borrower will not be liable under the Transaction Documents for any amount paid by an Indemnified Person to settle any claims or actions if the settlement is entered into without the Borrower’s consent (which consent shall not be unreasonably withheld, delayed or conditioned), provided that this section 6.11(f) shall not apply to those settlements where the Borrower was offered the ability to assume the defense of the action that directly and specifically related to the subject matter of such settlement and elected not to assume such defense.

43

(e) TO THE EXTENT PERMITTED BY LAW, NO PARTY HERETO SHALL ASSERT, AND EACH PARTY HERETO HEREBY WAIVES, ANY CLAIM AGAINST ANY INDEMNIFYING PARTY HEREUNDER, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGE (AS OPPOSED TO DIRECT OR ACTUAL DAMAGES) ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF THIS AGREEMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

Section 6.12 No Usury. The Transaction Documents are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or agreed to be paid to the Lenders for the Loan exceed the maximum amount permissible under applicable law. If from any circumstance whatsoever fulfillment of any provision hereof, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstance the Lenders shall ever receive anything which might be deemed interest under applicable law that would exceed the highest lawful rate, such amount that would be deemed excessive interest shall be applied to the reduction of the principal amount owing on account of the Loan, or if such deemed excessive interest exceeds the unpaid balance of principal of the Loan, such deemed excess shall be refunded to the Borrower. All sums paid or agreed to be paid to the Lenders for the Loan shall, to the extent permitted by applicable law, be deemed to be amortized, prorated, allocated and spread throughout the full term of the Loan until payment in full so that the deemed rate of interest on account of the Loan is uniform throughout the term thereof. The terms and provisions of this Section shall control and supersede every other provision of this Agreement and the Notes.

Section 6.13 Further Assurances. From time to time, the Parties shall perform any and all acts and execute and deliver to the other parties hereto such additional documents as may be necessary or as requested by any Party to carry out the purposes of any Transaction Document or any or to preserve and protect rights of such Party as contemplated therein.

Section 6.14 Confidentiality.

(a) Lenders agree that they will hold any confidential information they may receive from Borrower in connection with The Transaction Documents in confidence, 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 6.14(a) by Lenders), (b) is or has been independently developed or conceived by Lenders without use of Borrower’s confidential information, or (c) is or has been made known or disclosed to Lender by a third party without a breach of any obligation of confidentiality such third party may have to Borrower; provided, however, that Lenders may disclose confidential information (i) to their attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with this Agreement and the other Transaction Documents; (ii) to any prospective purchaser of any Loan from Lenders, if a transfer to such prospective purchaser is permitted and such prospective purchaser agrees to be bound by the provisions of this Subsection 6.14(a); (iii) to any existing or prospective Affiliate, partner, member, shareholder, or wholly owned subsidiary of a Lender in the ordinary course of business, provided that Lenders inform such Person that such information is confidential and direct such Person to maintain the confidentiality of such information; (iv) as may otherwise be required by law, regulation or legal process; or (v) to any Person in connection with any legal proceeding to which it is a party.

44

(b) Notwithstanding anything to the contrary herein, in any Transaction Document or in any other agreement entered into on or before the Effective Date, in the event that the Borrower or any other Credit Party believes that a notice or communication to any Lender or to any officer, partner, employee or Affiliate of any Lender (collectively with the Lenders, the “Lender Parties”) or any other information that may be provided by or on behalf of the Borrower or any Credit Party to any of the Lender Parties contains material, nonpublic information relating to the Borrower, any Credit Party or any of their respective subsidiaries or Affiliates or any of their respective property, assets, securities or businesses, the Borrower shall so indicate to the applicable Lender Party contemporaneously with delivery of such notice, communication or information, and such indication shall provide such Lender Party the means to refuse to receive such notice or communication; and in the absence of any such indication, the Lender Party (and any other Lender Parties related thereto) shall be allowed to presume that all matters relating to such notice, communication or information do not constitute material, nonpublic information relating to the Borrower, any Credit Party or any of their respective subsidiaries or Affiliates or any of their respective property, assets, securities or businesses. No Lender Party shall have any duty of trust or confidence with respect to, or any obligation not to trade in any securities on the basis of, any material nonpublic information regarding the Borrower, any Credit Party or any of their respective subsidiaries or Affiliates or any of their respective property, assets, securities or businesses provided by, or on behalf of, the Borrower, any Credit Party, any of their respective subsidiaries, any of their respective Affiliates or any of their respective officers, directors, employees, attorneys, representatives or agents, in violation of any of the covenants set forth in this Subsection 6.14(b) or that is otherwise possessed (or continued to be possessed) by any Lender Party as a result of a breach of any of the covenants set forth in this Subsection 6.14(b).

Section 6.15 Credit Analysis. Each Lender shall be responsible for keeping itself informed of (a) the financial condition of the Borrower and all other Credit Parties and (b) all other circumstances bearing upon the risk of nonpayment of the Obligations hereunder, and have made and shall continue to make, independently and without reliance upon each other, its own credit analysis and decision in entering into the documents to which it is a party and taking or not taking any action thereunder. None of the Lenders shall have any duty to advise any other Lender of information known to it regarding such condition or any such other circumstances, and no disclosure of any such information shall create any obligation to provide any further information to be deemed to constitute or require any representation or warranty from the disclosing Lender regarding that or any other information. No Lender assumes any liability to any other Person with respect to: (i) the financial or other condition of the Borrower and all other Credit Parties, (ii) the enforceability, validity, value or collectability of the Loans, any collateral therefor or any guarantee or security which may have been granted in connection with any of the Obligations hereunder or under any other Transaction Document, (iii) any Credit Party’s title or right to transfer any collateral or security or (iv) any other circumstance that might bear on the risk of nonpayment of the Obligations.

45

Section 6.16 Sharing of Payments.

If any Lender, directly or through any of its Affiliates, obtains any payment of interest or principal on any of its Loans (whether voluntary, involuntary or through the exercise of any right of setoff or the receipt of any Collateral or “proceeds” (as defined under the UCC (as defined in the Guaranty and Security Agreement)) of Collateral) (and other than pursuant to Section 6.5) and such payment exceeds the amount such Lender would have been entitled to receive if all payments had gone to, and been distributed in accordance with the provisions of this Agreement and the other Transaction Documents, such Lender shall purchase for cash from the other Lenders such participations in their Loans as necessary for such Lender to share such excess payment with such Lenders to ensure such payment is applied as though it had been applied in accordance with this Agreement; provided, however, that (i) if such payment is rescinded or otherwise recovered from such Lender in whole or in part, such purchase shall be rescinded and the purchase price therefor shall be returned to such Lender without interest and (ii) such Lender shall, to the fullest extent permitted by Applicable Law, be able to exercise all its rights of payment (including the right of setoff) with respect to such participation as fully as if such Lender were the direct creditor of the applicable Credit Party in the amount of such participation.

Section 6.17 Collateral Agent.

(a) Each Lender hereby irrevocably appoints the DPDF Lender (together with any successor collateral agent appointed by DPDF Lender or any successor collateral agent that was appointed by the Required Lenders), as Collateral Agent hereunder and under the other Transaction Documents and authorizes Collateral Agent to (i) act as the agent of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral (as defined in the Guaranty and Security Agreement) granted by any of the Credit Parties to secure any of the Obligations, (ii) execute and deliver the Transaction Documents to which it is a party and accept delivery thereof on its behalf from any Credit Party, (iii) take such other actions on its behalf and to exercise all rights, powers and remedies and perform the duties as are expressly delegated to Collateral Agent under the Transaction Documents, including without limitation, file any financing statements in a representative capacity, and (iv) exercise such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Transaction Document, Collateral Agent shall not have any duty or responsibility except those expressly set forth herein or therein; nor shall Collateral Agent have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Transaction Document or otherwise exist against Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “collateral agent” or “agent” herein and in other Transaction Documents with reference to Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. The provisions of this Section 6.17 are solely for the benefit of the Collateral Agent and the Lenders and none of the Borrower or the other Credit Parties shall have any rights as a third party beneficiary of any of the provisions of this Section 6.17, except with respect to the Borrower’s consultation rights in connection with the appointment of a successor Collateral Agent as set forth in Section 6.17(h) hereof. In performing its functions and duties under this Agreement and the other Transaction

46

Documents, Collateral Agent shall act solely as collateral agent of Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for any Borrower or any other Credit Party. Collateral Agent shall have the same rights and powers under the Transaction Documents as any other Lender and may exercise or refrain from exercising the same as though it were not Collateral Agent, and Collateral Agent and its Affiliates may lend money to, invest in and generally engage in any kind of business with each Credit Party, Affiliate of any Credit Party as if it were not Collateral Agent hereunder.

(b) Collateral Agent may execute any of its duties under this Agreement or any other Transaction Document by or through agents, subagents, employees or attorneys in fact, and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties and any Person shall benefit from this Section 6.17. Collateral Agent shall not be responsible for the negligence or misconduct of any agent, subagent or attorney in fact that it selects in the absence of gross negligence or willful misconduct as determined by a final, non-appealable judgment of a court of competent jurisdiction.

(c) Neither Collateral Agent nor any of its directors, officers, employees, attorneys, advisors, representatives or agents shall (i) be liable to any Lender for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Transaction Document or the transactions contemplated hereby or thereby (except to the extent resulting from its own gross negligence or willful misconduct in connection with its duties expressly set forth herein as determined by a final, non-appealable judgment of a court of competent jurisdiction), or (ii) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by any Credit Party or Affiliate of any Credit Party, or any officer thereof, contained in this Agreement or in any other Transaction Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Collateral Agent under or in connection with, this Agreement or any other Transaction Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Transaction Document (or the creation, perfection or priority of any Lien or security interest therein), or for any failure of any Credit Party or any other party to any Transaction Document to perform its obligations (including the Obligations) hereunder or thereunder. Collateral Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Transaction Document, or to inspect the properties, books or records of any Credit Party or any Credit Party’s Affiliates.

(d) Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any communication believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to any Credit Party), independent accountants and other experts selected by Collateral Agent. Collateral Agent shall be fully justified in failing or refusing to take any action under any Transaction Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so requests, confirmation from the Lenders of their obligation to indemnify Collateral Agent

47

against any and all liabilities and expenses (including any fees and expenses of counsel to Collateral Agent) that may be incurred by it by reason of taking or continuing to take any such action. Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under any Transaction Document in accordance with a request or consent of the Required Lenders and such request and any action taken or failure to act pursuant thereto shall be binding upon each Lender.

(e) Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Event of Default or Default, unless Collateral Agent shall have received written notice from a Lender or any Credit Party referring to this Agreement and the other Transaction Documents, describing such Event of Default or Default and stating that such notice is a “notice of default.” Collateral Agent shall take such action with respect to such Event of Default or Default as the Required Lenders may direct; provided that, unless and until Collateral Agent has received any such request, Collateral Agent shall not take any such action, or refrain from taking any such action, with respect to such Event of Default or Default.

(f) Each Lender acknowledges that Collateral Agent has not made any representation or warranty to it, and that no act by Collateral Agent hereafter taken, including any consent and acceptance of any assignment or review of the affairs of the Credit Parties or any of their Subsidiaries, shall be deemed to constitute any representation or warranty by Collateral Agent to any Lender as to any matter, including whether Collateral Agent has disclosed material information in its possession. Each Lender represents to Collateral Agent that it has, independently and without reliance upon Collateral Agent and based on such documents and information as it has deemed appropriate, made its own appraisal of, and investigation into, the business, prospects, operations, property, financial and other condition and creditworthiness of Borrower and the other Credit Parties, and made its own decision to enter into this Agreement and the other Transaction Documents and to extend credit to Borrower hereunder and under the other Transaction Documents. Each Lender also represents that it will, independently and without reliance upon Collateral Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Transaction Documents, and to make such investigations as it deems necessary or appropriate to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of Borrower and the other Credit Parties. Except for notices, reports and other documents expressly herein or in the Guaranty and Security Agreement required to be furnished to the Lenders by Collateral Agent, Collateral Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial or other condition or creditworthiness of Borrower or any other Credit Party that may come into the possession of Collateral Agent.

(g) Other than with respect to the matters described in clause (i) below, which shall be governed by such clause, whether or not the transactions contemplated hereby are consummated, each Lender shall severally indemnify upon demand Collateral Agent and its directors, officers, partners, employees, attorneys, advisors, representatives and agents (to the extent not reimbursed by or on behalf of any Credit Party and without limiting the

48

obligation of the Credit Parties to do so), according to its Pro Rata Share, from and against any and all losses, claims (including the reasonable attorneys’ fees incurred in defending against such claims), damages, liabilities, penalties or other expenses arising out of, or relating to, any of Collateral Agent’s duties, responsibilities or actions set forth in or that taken pursuant to the Transaction Documents; provided that no Lender shall be liable for any payment to any such Person of any portion of the foregoing to the extent determined by a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the applicable Person’s gross negligence or willful misconduct. No action taken (or in refraining from having taken action) in accordance with the directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 6.17(g). Without limitation of the foregoing, each Lender shall reimburse Collateral Agent upon demand for such Lender’s ratable share of any costs or out of pocket expenses incurred by Collateral Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Transaction Document or any document contemplated by or referred to herein or therein, to the extent that Collateral Agent is not reimbursed for such fees, costs and expenses by or on behalf of the Credit Parties. The undertaking in this Section 6.17(g) shall survive repayment of the Loans and the other Obligations, any foreclosure under, or modification, release or discharge of, any or all of the Transaction Documents, termination of this Agreement or the other Transaction Documents and the resignation or replacement of Collateral Agent.

(h) Collateral Agent may resign as Collateral Agent upon thirty (30) days’ notice to the Lenders and Borrower, and the Required Lenders have the right, at their sole election, to remove the Person serving as Collateral Agent upon ten (10) days’ notice to Collateral Agent (or immediately upon any material breach of Collateral Agent of its obligations under the Transaction Documents). If Collateral Agent resigns under this Agreement or the Required Lenders remove the Person serving as Collateral Agent, the Required Lenders (in consultation with the Borrower) shall appoint from among the Lenders a successor Collateral Agent for such successor Collateral Agent and the Lenders. If no successor Collateral Agent is appointed prior to the effective date of the resignation or removal of Collateral Agent, Collateral Agent may appoint, after consulting with the Lenders and the Borrower, a successor Collateral Agent from among the Lenders. Upon the acceptance of its appointment as successor Collateral Agent hereunder, such successor Collateral Agent shall succeed to all the rights, powers and duties of the retiring or removed Collateral Agent, and the term “Collateral Agent” shall mean such successor Collateral Agent, and the retiring or removed Collateral Agent’s appointment, powers and duties as Collateral Agent shall be immediately and automatically terminated at such time. After any retiring Collateral Agent’s resignation or removal hereunder as Collateral Agent, the provisions of this Section 6.17 shall inure to its benefit (in its capacity as Collateral Agent) as to any actions taken or omitted to be taken by it while it was Collateral Agent under this Agreement and the other Transaction Documents. If no successor Collateral Agent has accepted appointment as Collateral Agent by the date that is thirty (30) days following a retiring Collateral Agent’s notice of resignation (or at the time of removal of a Person as Collateral Agent), the retiring Collateral Agent’s resignation or removal shall nevertheless thereupon become effective, and the Required Lenders shall perform all of the duties of Collateral Agent hereunder until such time, if any, as the Required Lenders appoint a successor Collateral Agent as provided for above.

49

(i) Each Lender further agrees to indemnify Collateral Agent, its Affiliates and each of its and their employees, advisors, attorneys, representatives and agents (to the extent not reimbursed by any Credit Party), severally and ratably, from and against Liabilities (including Taxes, interests and penalties imposed for not properly withholding or backup withholding on payments made to or for the account of any Lender) that may be imposed on, incurred by or asserted against Collateral Agent, its Affiliates or any of its or their employees, advisors, attorneys, representatives or agents in any matter relating to or arising out of, in connection with or as a result of any Transaction Document or any other act, event or transaction related, contemplated in or attendant to any such document, or, in each case, any action taken or omitted to be taken by Collateral Agent, its Affiliates or any of its or their employees, advisors, attorneys, representatives or agents under or with respect to any of the foregoing.

(j) Notwithstanding any provision in any Transaction Document to the contrary, the Lenders hereby irrevocably authorize Collateral Agent, based upon the written instruction of the Required Lenders, to (a) credit bid and in such manner purchase (either directly or through one or more acquisition vehicles) all or any portion of the Collateral at any sale thereof conducted under the provisions of the Bankruptcy Code, including under Section 363 of the Bankruptcy Code or any similar laws in any other jurisdictions to which a Credit Party is subject, or (b) credit bid and in such manner purchase (either directly or through one or more acquisition vehicles) all or any portion of the Collateral at any other sale or foreclosure conducted by (or with the consent or at the direction of) Collateral Agent (whether by judicial action or otherwise) in accordance with Applicable Law. In connection with any such credit bid and purchase, the Obligations owed to the Lenders shall be entitled to be, and shall be, credit bid on a ratable basis (with Obligations with respect to contingent or unliquidated claims being estimated for such purpose if the fixing or liquidation thereof would not unduly delay the ability of Collateral Agent to credit bid and purchase at such sale or other disposition of the Collateral and, if such claims cannot be estimated without unduly delaying the ability of Collateral Agent to credit bid, then such claims shall be disregarded, not credit bid, and not entitled to any interest in the asset or assets purchased by means of such credit bid) and the Lenders whose Obligations are credit bid shall be entitled to receive interests (ratably based upon the proportion of their Obligations credit bid in relation to the aggregate amount of Obligations so credit bid) in the asset or assets so purchased (or in the stock of the acquisition vehicle or vehicles that are used to consummate such purchase). Except as provided above and otherwise expressly provided for herein or in the other Transaction Documents, Collateral Agent will not execute nor deliver a release of any Lien on any Collateral. Upon request by Collateral Agent at any time, the Lenders will confirm in writing Collateral Agent’s authority to release any such Liens on particular types or items of Collateral pursuant to, and in accordance with, this Section 6.17(j). Each Lender whose Obligations are credit bid under this Section 6.17(j) shall be entitled to receive interests in the Collateral or any other asset acquired in connection with such credit bid (or in the stock of the acquisition vehicle or vehicles that are used to consummate such acquisition) on a ratable basis in accordance with the percentage obtained by dividing (y) the amount of Obligations of such Lender that were credit bid in such credit bid by (z) the aggregate amount of all Obligations that were credit bid in such credit bid.

50

Section 6.18 Cost and Expense Reimbursement. The Credit Parties agree to pay within ten (10) Business Days after delivery of an invoice therefor, (a) all reasonable and documented fees, costs and expenses of the Lenders, including one counsel for the Required Lenders selected by the Required Lenders, in connection with the administration of the Facility Agreement and the other Loan Documents and the negotiation, preparation, execution and administration of any consents, amendments, waivers or other modifications thereto and any other documents or matters requested by the Borrower or any other Credit Party related thereto, (b) all reasonable and documented out-of-pocket expenses incurred by the Collateral Agent or the Lenders, including, without limitation, the reasonable and documented fees, disbursements and other charges of one primary firm of counsel for the Collateral Agent and the Lenders, taken as a whole, (and if reasonably necessary (as determined by the Collateral Agent in consultation with the Borrower)), of a single local counsel in each appropriate jurisdiction and, in the case of an actual or potential conflict of interest where the Collateral Agent or any Lender affected by such conflict informs the Borrower of such conflict and thereafter retains its own counsel, of another primary firm of counsel for such affected person in connection with the enforcement or protection of its rights in connection with this Agreement or any other Transaction Document, including its rights under this Section 6.18, or in connection with the Loans made hereunder, including all such reasonable and documented out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans and (c) the cost of purchasing insurance that the Credit Parties fail to obtain as required by the Transaction Documents. The obligations and provisions contained in this Section 6.18 shall survive the termination of this Agreement and the repayment of the Obligations.

(“DSCM”) are entering into the December 2019 Exchange Agreement and Amendment to Facility Agreement, Senior Secured Convertible Notes and Warrants (the “December 2019 Exchange Agreement”), pursuant to which, among other things, the Lenders and DSCM are exchanging all of their Indenture Notes for Senior Secured Convertible Notes of the Borrower in substantially the form attached as an exhibit thereto. The Senior Secured Convertible Notes being issued to the Lenders pursuant to the December 2019 Exchange Agreement and the Facility Agreement are referred to herein as the “December 2019 Notes.” References herein to the “Facility Agreement” mean the Facility Agreement, as amended by the December 2019 Exchange Agreement.

D. Pursuant to this Agreement, the Borrower and the Lenders desire to provide the Lenders (and not, for the avoidance of doubt, either Non-Deerfield Lender) the right and option to exchange December 2019 Notes for shares of Common Stock (based on an exchange price of at least $0.60 per share of Common Stock) or shares of Series B-2 Preferred Stock of the Borrower substantially in accordance with the terms of Annex I to the September Exchange Agreement, as amended by this Agreement.

At any time and from time to time on or after the Effective Time (as defined in, and determined in accordance with, the December 2019 Exchange Agreement), the Lenders (and their assignees) shall have the right and option, but not the obligation, to exchange the principal amount of the December 2019 Notes or FA Notes (as defined in Exhibit A hereto) for shares of Common Stock or Series B-2 Preferred Stock in accordance with Annex I to the September Exchange Agreement, as amended and restated in accordance with Section 1.02 of this Agreement (any such exchange, an “Optional Exchange”).

The Borrower is not, and never has been, a “shell company” (as defined in Rule 12b-2 under the Exchange Act) and is not an issuer of a type identified in, or subject to, Rule 144(i)(1) under the Securities Act.

(i) No Integrated Offering. Neither the Borrower, nor any of its affiliates, nor any person acting on its or their behalf has, directly or indirectly, made, or will make, any offers or sales of any security or solicited, or will solicit, any offers to buy any security, under circumstances that would cause the offering and issuance of the Option Exchange Shares or the offering and issuance of any of the Conversion Shares to be integrated with prior or contemporaneous offerings by the Borrower (i) for purposes of the Securities Act and which would require the registration of any such securities under the Securities Act, or (ii) for purposes of any applicable stockholder approval provisions of the Nasdaq GM and which would require stockholder approval for the issuance of any Option Exchange Shares or Conversion Shares.

(j) No Bad Actor Disqualification. None of the Credit Parties, any of its predecessors, any director, executive officer, other officer of any Credit Party participating in the offering of the Exchange Shares or the Conversion Shares, any beneficial owner (as that term is defined in Rule 13d-3 under the Exchange Act) of 20% or more of any Credit Party’s outstanding voting equity securities, calculated on the basis of voting power, any “promoter” (as that term is

6

defined in Rule 405 under the Securities Act) connected with any Credit Party at the time this representation is made, any placement agent or dealer participating in the offering of the Exchange Shares or the Conversion Shares and any of such agents’ or dealer’s directors, executive officers, other officers participating in the offering of the Notes or the Conversion Shares (each, a “Covered Person”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (a “Disqualification Event”). The Borrower has exercised reasonable care to determine (i) the identity of each person that is a Covered Person and (ii) whether any Covered Person is subject to a Disqualification Event. Each Credit Party has complied in all material respects, to the extent applicable, with its disclosure obligations under Rule 506(e). No Credit Party is any other reason disqualified from reliance upon Rule 506 of Regulation D for purposes of the offer, sale and issuance of the Exchange Shares or the Conversion Shares.

(k) Application of Takeover Protections. The Borrower and its board of directors have taken all necessary action, if any, in order to render inapplicable the Borrower’s issuance of the Option Exchange Shares and Conversion Shares and the Lenders’ ownership of such securities from the provisions of any control share acquisition, interested stockholder, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the organizational documents of the Borrower or the laws of the state of its incorporation which is applicable to the Lenders as a result of the transactions contemplated by this Agreement, including the Borrower’s issuance of the Option Exchange Shares and Conversion Shares and the Lenders’ ownership of such securities.

(a) Exchange at Option of each Lender.

If the issuance would result in the issuance of a fraction of a share of Common Stock, then the Borrower shall round such fraction of a share up or down to the nearest whole share (with 0.5 rounded up).

(b) Exchange Rate. The number of Option Exchange Shares issuable upon an Exchange of a Note (or portion thereof) pursuant to Section 2 of this Annex I shall be determined according to the following formula (the “Exchange Rate”):

(c) Mechanics of Exchange. The Exchange of the Notes shall be conducted in the following manner:

(i) Lender’s Delivery Requirements. To exchange a Note (or any portion thereof) for Option Exchange Shares on any date, the applicable Lender shall 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 exchange notice in the form attached hereto as Exhibit A (the “Exchange Notice”) to the offices of the Borrower, at 1180 Celebration Blvd., Suite 103, Celebration, FL 34747, Attention: R. LaDuane Clifton, Chief Financial Officer, Fax: (321) 250-3698, E-mail: lclifton@kempharm.com, or such other address, facsimile number or email address as the Borrower may designate in writing. Notwithstanding anything to the contrary set forth herein, in connection with any Lender’s exchange of a Note (or portion thereof), pursuant hereto, such Lender shall not be required to physically surrender the applicable Note to the Borrower unless the entire principal amount thereof is being exchanged. Each Lender and the Borrower shall maintain records showing the principal amount of Notes exchanged by such Lender hereto, the dates of any such exchanges by such Lender (and also, for the avoidance of doubt, any conversions of the Notes by such Lender) and the number of shares of Common Stock and Series B-2 Preferred Stock issued pursuant hereto or shall use such other method, reasonably satisfactory to such Lender and the Borrower so as not to require physical surrender of any Note upon any partial exchange. For the avoidance of doubt, each Lender shall have the right to deliver an Exchange Notice that provides for the issuance of both shares of Common Stock and shares of Series B-2 Preferred Stock.

(ii) Borrower’s Response. Upon receipt or deemed receipt by the Borrower of a copy of an Exchange Notice from a Lender, the Borrower (I) shall as soon as practicable send, via electronic mail, a confirmation of receipt of such Exchange Notice to such Lender and the Borrower’s designated transfer agent (the “Transfer Agent”), if applicable, which confirmation shall constitute an instruction to any such Transfer Agent to process such Exchange Notice in accordance with the terms herein and (II) within the Standard Settlement Period following the date of receipt or deemed receipt by the Borrower of such Exchange Notice (the “Share Delivery Date”), (A) in respect of the number Option Exchange Shares (if any) comprised of shares of Common Stock, credit such aggregate number of shares of Common Stock to which such Lender shall be entitled in connection with such Exchange Notice, to the account of the Lender’s prime broker with DTC through its Deposit/Withdrawal at Custodian (DWAC) system, or (B) in respect of the number of Option Exchange Shares comprised of Series B-2 Preferred Shares (if any), issue and deliver to the address specified in the Exchange Notice, a stock certificate, registered in the name of the Lender (or

its nominee) or such other persons as designated by the Lender, for the number of Series B-2 Preferred Shares to which the Lender shall be entitled in connection with such Exchange Notice. Provided that the Lender to which Option Exchange Shares are to be issued represents that (x) as of the date of delivery of the applicable Exchange Notice it is not, and for a period of three (3) months prior to such date has not been, an “affiliate” (as such term is used in Rule 144 under the Securities Act) of the Borrower, and (y) the Note being converted has not been held by such an affiliate within the six (6)-month period immediately preceding the date of such Exchange Notice, the Option Exchange Shares shall not be subject to restrictions on transfer, and shall not bear any legend or be subject to any stop transfer or similar instruction. For the avoidance of doubt, by delivering an Exchange Notice, a Lender shall be deemed to have made the representations contemplated by the immediately preceding sentence, unless the applicable Lender otherwise indicates in such Exchange Notice. All interest in respect of the principal amount of the Exchange Notes to which an Exchange Notice relates that has accrued and is unpaid through the date the applicable Option Exchange Shares are delivered hereunder shall be paid by the Borrower in kind by adding the amount of such interest to the then outstanding principal amount of the Note to which the applicable Exchange related.

(iii) Dispute Resolution. In the case of a dispute between the Borrower and a Lender as to the determination of the Exchange Price or the arithmetic calculation of the Exchange Rate, the Borrower shall issue, or instruct the Transfer Agent to issue, as applicable, to such Lender the number of Option Exchange Shares that is not disputed and shall transmit an explanation of the disputed determinations or arithmetic calculations to such Lender via facsimile and email within two (2) Business Days of receipt or deemed receipt of such Lender’s Exchange Notice or other date of determination. If such Lender and the Borrower are unable to agree upon the determination of the Exchange Price or arithmetic calculation of the Exchange Rate within one (1) Business Day of such disputed determination or arithmetic calculation being transmitted to such Lender, then the Borrower shall promptly (and in any event within two (2) Business Days) submit via facsimile or email (A) the disputed determination of the Exchange Price to an independent, reputable investment banking firm agreed to by the Borrower and the Lender to which such dispute relates, or (B) the disputed arithmetic calculation of the Exchange Rate to the Borrower’s independent registered public accounting firm, as the case may be. The Borrower 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 Borrower and the Lender to which such dispute relates 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 to such dispute absent manifest error. The fees and expenses of such investment bank or accounting firm shall be paid by the Borrower.

(iv) Record Holder. The person or persons entitled to receive the Option Exchange Shares issuable upon an Exchange of a Note (or portion thereof) hereunder shall be treated for all purposes as the legal and record holder or holders of such Option Exchange Shares upon delivery of the Exchange Notice in respect of such Exchange, or in the case of Option Exchange 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) of this Annex I, the first Business Day after the resolution of such bona fide dispute; provided that the principal amount of the Notes subject to such dispute shall continue to bear interest until the date such Option Exchange Shares are actually issued to the applicable Lender.

(v) Borrower’s Failure to Timely Exchange.

(A) Cash Damages. If, on or before the Share Delivery Date, the Borrower shall fail to issue and deliver to the applicable Lender in accordance with Section 2(c)(ii) of this Annex I the number of Option Exchange Shares (free of any restrictive legend or stop transfer instructions) to which such Lender is entitled upon its Exchange of any Exchange Amount, then in addition to all other available remedies that such Lender may pursue hereunder, then the Borrower shall pay as partial liquidated damages to such Lender for each 30-day period (prorated for any partial period) after the Share Delivery Date such Exchange is not timely effected an amount equal to one percent (1%) of the Exchange Amount. Notwithstanding anything to the contrary contained herein (and in addition to the remedies set forth herein), to the extent that the Borrower shall fail to issue and deliver Option Exchange Shares to the applicable Lender prior to the applicable Share Delivery Date, the principal amount of the Notes to which such failure relates shall continue to bear interest until the date such Option Exchange Shares are actually issued to the applicable Lender. If the Borrower fails to pay the additional damages set forth in this Section 2(c)(v)(A) of this Annex I or interest that accrues in accordance with the immediately preceding sentence or Section 2(c)(iv), in each case, within five (5) Business Days of the date incurred, then the Lender entitled to such payments shall have the right at any time, so long as the Borrower continues to fail to make such payments, to require the Borrower, upon written notice, to immediately issue, in lieu of such damages or interest payments described herein, the number of shares of Common Stock equal to the quotient of (X) the aggregate amount of the damages payments described in this Section 2(c)(v)(A) of this Annex I divided by (Y) the Common Stock Exchange Price in effect on such Exchange Date.

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

(d) Taxes. The Borrower shall pay any and all taxes (excluding income taxes, franchise taxes or other taxes levied on gross earnings, profits or the like of each Lender) that may be payable with respect to the issuance and delivery of Option Exchange Shares upon the Exchange of Notes (or any portion thereof) hereunder.

(e) Limitations on Exchange.

(i) Option Beneficial Ownership Cap. The Borrower shall not issue to a Lender, and a Lender may not acquire, a number of shares of Common Stock upon Exchange of such Lender’s Notes pursuant to this Annex I to the extent that, upon such Exchange, the number of shares of Common Stock then beneficially owned by such Lender and its Affiliates and any other Persons or entities whose beneficial ownership of the Common Stock would be aggregated with such Lender for the purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which such Lender 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 in this Section 2(e)(i)) would exceed 4.985% of the total number of the shares of the Common Stock then issued and outstanding (the “Option Beneficial Ownership Cap”); provided, that the Option Beneficial Ownership 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. Each Lender hereby agrees that delivery by a Lender of an Exchange Notice that provides for the exchange of a Note (or any portion thereof) for Common Stock shall constitute a representation by such Lender that the issuance of shares of Common Stock in accordance with such Exchange Notice will not cause such Lender (together with such Lender’s Affiliates, and any other Person whose beneficial ownership of Common Stock would be aggregated with such Lender’s for purposes of Section 13(d) of the Exchange Act and the applicable regulations of the Commission) to beneficially own a number of shares of Common Stock in excess of the Option Beneficial Ownership Cap. For purposes of the foregoing representation, the number of shares of Common Stock beneficially owned by such Lender and its Affiliates shall include the number of shares of Common Stock issuable upon exchange of the Note (or portion thereof) subject to the Exchange Notice with respect to which such representation is being made, but shall exclude the number of shares of Common Stock which are issuable upon (A) exchange pursuant to this Annex I of the remaining, unexchanged Notes beneficially owned by such Lender and (B) exercise, conversion or exchange of the unexercised, unconverted or unexchanged portion of any shares of Series B-1 Preferred Stock or Series B-2 Preferred Stock or any other securities of the Borrower subject to a limitation on conversion, exercise or exchange analogous to the limitation contained herein (including any warrants) beneficially owned by such Lender or any of its Affiliates. Except as set forth in the preceding sentence, for purposes hereof, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. In addition, a determination as to any “group” status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes hereof, in determining the number of outstanding shares of Common Stock, a Lender may rely on the number of outstanding

shares of Common Stock as stated in the Borrower’s most recent quarterly or annual report filed with the Commission, or any current report filed by the Borrower with the Commission subsequent thereto. In addition, if in response to a request by a Lender (which may be via electronic mail), the Borrower confirms in writing via electronic mail to such Lender the number of shares of Common Stock then outstanding, each Lender shall be entitled to rely upon such confirmation. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion, exercise or exchange of securities of the Borrower, including shares of Series B-1 Preferred Stock or Series B-2 Preferred Stock, by such Lender or its Affiliates since the date as of which such number of outstanding shares of Common Stock was last publicly reported or reported to such Lender by the Borrower in accordance with the foregoing, whichever is later.

(ii) Pro Rata Exchange Limit. Notwithstanding anything to the contrary contained herein, the Notes shall not be exchangeable by a Lender pursuant to this Annex I, and the Borrower shall not issue Option Exchange Shares to such Lender upon any Exchange pursuant to this Annex I, to the extent that the number of shares of Common Stock to be issued in such Exchange, and/or the number of Underlying Shares in respect of the Series B-2 Preferred Stock to be issued in such Exchange (as applicable), to such Lender, would exceed such Lender’s Pro Rata Exchange Limit (provided, for the avoidance of doubt, that the Borrower shall exchange the maximum amount of Notes set forth in the applicable Exchange Notice that may be exchanged into Option Exchange Shares without so exceeding such Lender’s Pro Rata Exchange Limit, subject, in the case of Option Exchange Shares comprised of Common Stock, to the Option Beneficial Ownership Cap, as applicable). Notwithstanding anything to the contrary contained herein, the aggregate number of shares of Common Stock issued as, or issuable upon conversion of, the Option Exchange Shares issued in all Exchanges under this Annex I shall not exceed the Option Exchange Share Cap.

3. Assignment. The rights of the Lenders under this Annex I shall not be assignable by any Lender without the prior written consent of the Borrower, except that a Lender may assign its rights under this Annex I, in whole or in part, without the consent of the Borrower to an Affiliate of such Lender to which it transfers or assigns all or any portion of such Lender’s Notes, provided that (a) such Lender agrees in writing with the transferee or assignee to assign such rights, and such assignee or transferee agrees in writing to accept such rights subject to, and to be bound by, the terms of this Annex I, and a copy of such agreement is furnished to the Borrower after such transfer or assignment; and (b) the Borrower is, after such transfer or assignment, furnished with written notice of (i) the name and address of such transferee or assignee and (ii) the portion of such Lender’s Pro Rata Exchange Limit with respect to which such rights are being transferred or assigned. Upon any such assignment or transfer, the definition of “Pro Rata Exchange Limit” shall be appropriately adjusted and Schedule A-1 shall be appropriately updated to reflect such assignment.

2. Conversion Rights. This Note may be converted into shares of Common Stock on the terms and conditions set forth in this Section 2.

(a) Conversion at Option of the Holder. At any time, the Holder shall be entitled to convert all or any part of the Principal (and the Interest Amount thereon) or any Interest accrued hereunder into fully paid and nonassessable shares of Common Stock (the “Conversion Shares”) in accordance with this Section 2 at the Conversion Rate (as defined in Section 2(b)). The Company shall not issue any fraction of a Share upon any conversion. If the issuance would result in the issuance of a fraction of a Share, then the Company shall round such fraction of a Share up or down to the nearest whole share (with 0.5 rounded up).

(b) Conversion Rate. The number of Conversion Shares issuable upon a conversion of any portion of this Note pursuant to this Section 2 shall be determined according to the following formula (the “Conversion Rate”):

(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 on any date (the “Conversion Date”), 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, 1180 Celebration Blvd., Suite 103, Celebration, FL 34747 (Attention: Chief Financial Officer, Fax: (321) 250-3698, Email: lclifton@kempharm.com), or such other address, facsimile number or

5

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, the Company (I) shall as soon as practicable send, via facsimile or electronic mail, 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 in accordance with the terms herein and (II) on or before the second (2^nd) Trading Day (or, if earlier, the last day of the Standard Settlement Period) following the date of receipt or deemed receipt by the Company of such Conversion Notice (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 two (2) Trading Days after receipt of this Note (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.

6

(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 as of immediately following the delivery of the Conversion Notice applicable to such conversion, or in the case of 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, subject to the terms of Section 2(e) hereof) 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 Notice 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 (10^th) 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.

7

(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; Delivery of Electronic Shares.

(i) Unless the Holder is an Affiliate of the Company as of the Issuance Date, neither this Note nor any note issued in substitution or replacement of this Note (or portion thereof) shall contain or be subject to, any legend, stop transfer instruction or similar notation, in each case, restricting the transfer hereof or thereof. Provided the Holder to which Conversion Shares are to be issued represents that it is not as of the applicable Conversion Date, and for a period of three (3) months prior to the applicable Conversion Date has not been, an “affiliate” (as such term is used in Rule 144 under the Securities Act) of the Company, upon each conversion of this Note (in whole or in part) the Conversion Shares shall be issued and delivered without (and without being subject to) any legend, stop transfer instruction or similar notation, in each case, restricting the transfer hereof or thereof. For the avoidance of doubt, by delivering a Conversion Notice, the Holder shall be deemed to have made the representations contemplated by the immediately preceding sentence as of the applicable Conversion Date, unless the applicable Holder otherwise indicates in such Conversion Notice. The Company shall use best efforts to cause its counsel to issue a legal opinion to the Transfer Agent, if required by the Transfer Agent to issue certificates evidencing the Conversion Shares without restrictive legends (and without being subject to any stop transfer instruction or similar notation) in accordance with this Agreement.

8

(ii) Holder agrees that the issuance of Conversion Shares without any restrictive legends 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.

(iii) Delivery of Electronic Shares. In lieu of delivering physical certificates representing the Common Stock issuable upon conversion, or representing Conversion Shares, upon written request of Holder, the Company shall cause its Transfer Agent to electronically transmit the Conversion Shares issuable upon conversion of this Note to the Holder by crediting the account of Holder’s prime broker with the Depository Trust Company through its Deposit/Withdrawal at Custodian (DWAC) system. The time periods for delivery and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

(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 Issuance Date 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 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 (i) Common Stock or Convertible Securities (A) pursuant to any Convertible Securities or Options outstanding on the Issuance Date in accordance with the terms of such Convertible Securities in effect on the Issuance Date 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, (B) to a Lender in connection with the conversion or exchange of any Notes (as defined in the Facility Agreement) or the conversion or exchange of any Convertible Security or Options issued to a Lender pursuant to any such conversion or exchange of Notes, 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 (defined below).

9

Notwithstanding anything herein to the contrary, nothing in this Section 2(f)(i)(A) shall result in the Conversion Price of this Note, or any other Note, equaling a price per share less than $0.38 (subject to adjustment as provided herein (the “Floor Price”)).

Notwithstanding anything to the contrary contained in the immediately preceding paragraph, if the Company issues or sells any Common Stock, Convertible Securities, warrants, or Options in a firm commitment underwritten public offering (an “Underwritten Public Offering”), then for purposes of determining any adjustment to the Conversion Price under this Section 2(f)(i)(A) in respect of such Underwritten Public Offering the Fair Market Price shall be 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 then traded, listed or quoted on the date of execution of the underwriting agreement (the “Offering Effective Date”) between the Company and the underwriters in such offering, provided, that (x) if the Offering Effective Date is not a Trading Day, then the Fair Market Price shall be 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 then traded, listed or quoted on the Trading Day immediately preceding the Offering Effective Date and (y) if the underwriting agreement in such offering is executed prior to closing of trading on the principal securities exchange, trading market or quotation system on which shares of Common Stock are then traded, listed or quoted on a given date, then the Fair Market Price shall be the closing sale price per share of the Common Stock on such principal securities exchange, trading market or quotation system on the Trading Day immediately preceding such date.

Notwithstanding anything to the contrary contained herein, this Section 2(f)(i)(A) shall not apply to any issuance or sale of Common Stock by the Company if such issuance or sale is made in an “at the market offering” (as defined in Rule 415 under the Securities Act) at a Per Share Selling Price equal to or greater than the then applicable Conversion Price, provided that, if the Company makes any such sale of Common Stock at a Per Share Selling Price less than the then applicable Conversion Price then (x) this Section 2(f)(i)(A) shall apply, but (y), for purposes of calculating any adjustment of the Conversion Price hereunder, the Fair Market Price for such sale shall be the price per share at which shares of Common Stock are sold in such “at the market offering.”

Notwithstanding anything to the contrary contained herein, this Section 2(f)(i)(A) shall not apply to any issuance or sale of Common Stock, Convertible Securities or Options by the Company if such issuance or sale is made pursuant to the terms of (x) that certain Purchase Agreement, dated February 28, 2019, by and between the Company and Lincoln Park Capital Fund, LLC, (y) that certain Common Stock Sales Agreement, dated as of September 4, 2018, by and between the Company and RBC Capital Markets, LLC, or (z) that certain September 2019 Exchange Agreement and Amendment to Facility Agreement, dated as of September 3, 2019, by and among the Company, Deerfield Private Design Fund III, L.P. and Deerfield Special Situations Fund, L.P. (as amended as of the Issuance Date).

10

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.

(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: 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

11

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, provided that, for the avoidance of doubt, if a fee is paid to a placement agent, sales agent or party operating in a similar capacity for sales made in an “at the market offering” (as defined in Rule 415 under the Securities Act), such fee shall not be deducted from the selling price for purposes of determining the Per Share Selling Price hereunder. 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 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 and Floor 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, each of the Conversion Price and Floor 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, each of the Conversion Price and Floor Price in effect immediately prior to such combination will be proportionately increased.

12

(iii) Adjustment of Conversion Price and Floor 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 Price and Floor Price 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 and Floor 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 or mandatory conversion of all of the outstanding shares of the class or series of capital stock for which this Note is then convertible, 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 and the applicable Floor Price, 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 and the Floor Price so as to protect the rights of the Holder; provided that no such adjustment will increase the Conversion Price or the Floor Price as otherwise determined pursuant to this Section 2(f).

13

(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 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) Intentionally Deleted.

(h) Intentionally Deleted.

(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 Note 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 [4.985%/19.985%] of the total number of the shares of Common Stock then issued and outstanding (the “[4.985% Cap/19.985% Cap]”); provided that the [4.985%/19.985%] 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 [4.985%/19.985%] Cap shall not apply to an exercise effected following receipt of a Major Transaction Notice (as defined below) in respect of a Major Transaction 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. 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 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.

14

(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 this Note, including, without limitation, representing the appropriate number of shares of the Successor Entity, having similar conversion rights as this Note (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 this Note 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 (y) the date of the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, and (z) the 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, 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 Company’s certificate of incorporation, as it may be amended from time to time, 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.

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 this 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.

16

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 Required Note Holders. Any amendment so approved shall bind all holders of the Notes, provided that such amendment applies to all of the Notes on substantially the same basis.

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 this Note pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof.

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.

(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 on any date (the “Conversion Date”), 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, 1180 Celebration Blvd., Suite 103, Celebration, FL 34747 (Attention: Chief Financial Officer, Fax: (321) 250-3698, Email: lclifton@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, the Company (I) shall as soon as practicable send, via facsimile or electronic mail, 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 in accordance with the terms herein and (II) on or before the second (2^nd) Trading Day (or, if earlier, the last day of the Standard Settlement Period) following the date of receipt or deemed receipt by the Company of such Conversion Notice (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 two (2) Trading Days after receipt of this Note (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

6

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 as of immediately following the delivery of the Conversion Notice applicable to such conversion, or in the case of 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, subject to the terms of Section 2(e) hereof) 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 Notice 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 (10^th) 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

7

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.

(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; Delivery of Electronic Shares.

(i) Neither this Note nor any note issued in substitution or replacement of this Note (or portion thereof) shall contain or be subject to, any legend, stop transfer instruction or similar notation, in each case, restricting the transfer hereof or thereof. Provided the Holder to which Conversion Shares are to be issued represents that it is not as of the applicable Conversion Date, and for a period of three (3) months prior to the applicable Conversion Date has not been, an “affiliate” (as such term is used in Rule 144 under the Securities Act) of the Company, upon each conversion of this Note (in whole or in part) the Conversion Shares shall be issued and delivered without (and without being subject to) any legend, stop transfer instruction or similar notation, in each case, restricting the transfer hereof or thereof. For the avoidance of doubt, by delivering a Conversion Notice, the Holder shall be deemed to have made the representations contemplated by the immediately preceding sentence as of the applicable

Conversion Date, unless the applicable Holder otherwise indicates in such Conversion Notice. The Company shall use best efforts to cause its counsel to issue a legal opinion to the Transfer Agent, if required by the Transfer Agent to issue certificates evidencing the Conversion Shares without restrictive legends (and without being subject to any stop transfer instruction or similar notation) in accordance with this Agreement.

(ii) Holder agrees that the issuance of Conversion Shares without any restrictive legends 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.

(iii) Delivery of Electronic Shares. In lieu of delivering physical certificates representing the Common Stock issuable upon conversion, or representing Conversion Shares, upon written request of Holder, the Company shall cause its Transfer Agent to electronically transmit the Conversion Shares issuable upon conversion of this Note to the Holder by crediting the account of Holder’s prime broker with the Depository Trust Company through its Deposit/Withdrawal at Custodian (DWAC) system. The time periods for delivery and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

(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 Amended and Restated Date 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 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

9

provision shall not apply to any issuances or sales of (i) Common Stock or Convertible Securities (A) pursuant to any Convertible Securities or Options outstanding on the Issuance Date in accordance with the terms of such Convertible Securities in effect on the Issuance Date 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, (B) to a Lender in connection with the conversion or exchange of any Notes (as defined in the Facility Agreement) or the conversion or exchange of any Convertible Security or Options issued to a Lender pursuant to any such conversion or exchange of Notes, 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 (defined below).

Notwithstanding anything herein to the contrary, nothing in this Section 2(f)(i)(A) shall result in the Conversion Price of this Note, or any other Note, equaling a price per share less than $0.38 (subject to adjustment as provided herein (the “Floor Price”)).

Notwithstanding anything to the contrary contained in the immediately preceding paragraph, if the Company issues or sells any Common Stock, Convertible Securities, warrants, or Options in a firm commitment underwritten public offering (an “Underwritten Public Offering”), then for purposes of determining any adjustment to the Conversion Price under this Section 2(f)(i)(A) in respect of such Underwritten Public Offering the Fair Market Price shall be 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 then traded, listed or quoted on the date of execution of the underwriting agreement (the “Offering Effective Date”) between the Company and the underwriters in such offering, provided, that (x) if the Offering Effective Date is not a Trading Day, then the Fair Market Price shall be 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 then traded, listed or quoted on the Trading Day immediately preceding the Offering Effective Date and (y) if the underwriting agreement in such offering is executed prior to closing of trading on the principal securities exchange, trading market or quotation system on which shares of Common Stock are then traded, listed or quoted on a given date, then the Fair Market Price shall be the closing sale price per share of the Common Stock on such principal securities exchange, trading market or quotation system on the Trading Day immediately preceding such date.

Notwithstanding anything to the contrary contained herein, this Section 2(f)(i)(A) shall not apply to any issuance or sale of Common Stock by the Company if such issuance or sale is made in an “at the market offering” (as defined in Rule 415 under the Securities Act) at a Per Share Selling Price equal to or greater than the then applicable Conversion Price, provided that, if the Company makes any such sale of Common Stock at a Per Share Selling Price less than the then applicable Conversion Price then (x) this Section 2(f)(i)(A) shall apply, but (y), for purposes of calculating any adjustment of the Conversion Price hereunder, the Fair Market Price for such sale shall be the price per share at which shares of Common Stock are sold in such “at the market offering.”

10

Notwithstanding anything to the contrary contained herein, this Section 2(f)(i)(A) shall not apply to any issuance or sale of Common Stock, Convertible Securities or Options by the Company if such issuance or sale is made pursuant to the terms of (x) that certain Purchase Agreement, dated February 28, 2019, by and between the Company and Lincoln Park Capital Fund, LLC, (y) that certain Common Stock Sales Agreement, dated as of September 4, 2018, by and between the Company and RBC Capital Markets, LLC, or (z) that certain September 2019 Exchange Agreement and Amendment to Facility Agreement, dated as of September 3, 2019, by and among the Company, Deerfield Private Design Fund III, L.P. and Deerfield Special Situations Fund, L.P. (as amended as of the Amended and Restated Date).

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.

(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.

11

(III) “Exempt Issuances” shall mean: 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, provided that, for the avoidance of doubt, if a fee is paid to a placement agent, sales agent or party operating in a similar capacity for sales made in an “at the market offering” (as defined in Rule 415 under the Securities Act), such fee shall not be deducted from the selling price for purposes of determining the Per Share Selling Price hereunder. 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 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

12

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 and Floor 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, each of the Conversion Price and Floor 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, each of the Conversion Price and Floor Price in effect immediately prior to such combination will be proportionately increased.

(iii) Adjustment of Conversion Price and Floor 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 Price and Floor Price 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 and Floor 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 or mandatory conversion of all of the outstanding shares of the class or series of capital stock for which this Note is then convertible, 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 and the applicable Floor Price, 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.

13

(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 and the Floor Price so as to protect the rights of the Holder; provided that no such adjustment will increase the Conversion Price or the Floor 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 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) Intentionally Deleted.

(h) Intentionally Deleted.

(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 Note 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 4.985% of the total number of the shares of Common Stock then issued and outstanding (the “4.985% Cap”); provided that the 4.985% 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 4.985% Cap shall not apply to an exercise effected following receipt of a Major Transaction Notice (as defined below) in respect of a Major Transaction 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. 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).

14

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 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 this Note, including, without limitation, representing the appropriate number of shares of the Successor Entity, having similar conversion rights as this Note (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 this Note 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.”

15

(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 (y) the date of the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, and (z) the 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, 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 Company’s certificate of incorporation, as it may be amended from time to time, 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.

16

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 this 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 Required Note Holders. Any amendment so approved shall bind all holders of the Notes, provided that such amendment applies to all of the Notes on substantially the same basis.

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 this Note pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof.

17

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) Intentionally Deleted.

(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 this Note to be Transferred to each assignee. The Company shall effect the Transfer within three (3) Business Days (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.

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.

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.

18

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.

15. Interpretative Matters. Unless the context otherwise requires, (a) all references to Sections or Exhibits are to Sections or Exhibits contained in or attached to this Note, (b) each accounting term not otherwise defined in this Note has the meaning assigned to it in accordance with GAAP, (c) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter and (d) the use of the word “including” in this Note shall be by way of example rather than limitation.

The Company hereby agrees that it shall not raise the execution of facsimile, PDF or other reproduction of this Note, or the fact that any signature was transmitted by facsimile, e-mail or other similar electronic transmission device, as a defense to the Company’s execution of this Note. Notwithstanding the foregoing, the Company shall be required to deliver an originally executed Note to the Holder.

Any such financing statement, continuation statement or amendment may be signed by Collateral Agent on behalf of any Grantor and may be filed at any time in any jurisdiction.

12

(b) Each Grantor shall, at any time and from time and to time, take such steps as Collateral Agent may reasonably request for the Collateral Agent to insure the continued perfection and priority of the security interest of the Collateral Agent for the ratable benefit of itself and each of the Lenders in any of the Collateral and of the preservation of its rights therein.

(c) If any Grantor shall at any time, acquire a “commercial tort claim” (as such term is defined in the UCC) in excess of $25,000, such Grantor shall promptly notify the Collateral Agent thereof in writing and supplement Schedule 7, therein providing a reasonable description and summary thereof, and upon delivery thereof to the Collateral Agent, such Grantor shall be deemed to thereby grant to the Collateral Agent for the ratable benefit of itself and each of the Lenders (and such Grantor hereby grants to the Collateral Agent for the ratable benefit of itself and each of the Lenders) a Lien in and to such commercial tort claim and all proceeds thereof, all upon the terms of and governed by this Agreement.

(a) Keep the Collateral properly housed and insured for the full insurable value thereof against loss or damage by fire, theft, explosion, sprinklers, collision (in the case of motor vehicles) and such other risks as are customarily insured against by Persons engaged in businesses similar to that of Borrower, with such companies, in such amounts, with such deductibles, and under policies in such form, as shall be reasonably satisfactory to the Collateral Agent. Original (or certified) copies of certificates of insurance have been or shall be, within thirty (30) days following the date of this Agreement (or such longer period as the Collateral Agent may agree in its reasonable discretion), delivered to the Collateral Agent, together with evidence of payment of all premiums therefor, and shall contain an endorsement, in form and substance reasonably acceptable to the Collateral Agent, showing loss under such insurance policies payable to the Collateral Agent for the ratable benefit of itself and each of the Lenders. Such endorsement, or an independent instrument furnished to the Collateral Agent, shall provide that the insurance company shall give Collateral Agent at least ten (10) days written notice before any such policy of insurance is canceled for non-payment of premium and that no act, whether willful or negligent, or default of Grantors or any other Person shall affect the right of the Collateral Agent and the other Lenders to recover under such policy of insurance in case of loss or damage.

If Grantors at any time or times hereafter shall fail to obtain or maintain any of the policies of insurance required above under Section 5.11 (and provide evidence thereof to the Collateral Agent promptly following receipt of written request therefor from the Collateral Agent) or to pay any premium relating thereto, then the Collateral Agent, for the ratable benefit of itself and each of the Lenders, without waiving or releasing any obligation or default by Grantors hereunder, may (but shall be under no obligation to) obtain and maintain such policies of insurance and pay such premiums and take such other actions with respect thereto as the Collateral Agent deems advisable upon notice to Grantors. Such insurance, if obtained by the Collateral Agent, may, but need not, protect Grantors’ interests or pay any claim made by or against Grantors with respect to the Collateral. Such insurance may be more expensive than the cost of insurance Grantors may be able to obtain on its own and may be cancelled only upon Grantors providing evidence that it has obtained the insurance as required above. All sums disbursed by the Collateral Agent in connection with any such actions, shall constitute Secured Obligations payable upon demand.

6.2 Communications with Obligors; Grantors Remain Liable.

(a) The Collateral Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default communicate with obligors under the Receivables to verify with them to the Collateral Agent’s satisfaction the existence, amount and terms of any Receivables.

(b) Upon the written request of the Collateral Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify obligors on the Receivables that the Receivables have been assigned to the Collateral Agent for the ratable benefit of itself and each of the Lenders and that payments in respect thereof shall be made directly to the Collateral Agent for the ratable benefit of itself and each of the Lenders.

(c) Anything herein to the contrary notwithstanding, each Grantor shall remain liable in respect of each of the Receivables to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto.

(d) After the occurrence and during the continuance of an Event of Default, for the purpose of enabling the Collateral Agent to exercise rights and remedies under this Agreement, each Grantor hereby grants to the Collateral Agent an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to such Grantor) to use, license or sublicense any Intellectual Property now owned or hereafter acquired by such Grantor, and wherever the same may be located, and including in such license access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof.

6.3 Investment Property.

(a) Unless an Event of Default shall have occurred and be continuing and the Collateral Agent shall have given written notice to the relevant Grantor of the Collateral Agent’s intent to exercise its corresponding rights pursuant to Section 6.3(b), each Grantor shall be permitted to receive all cash dividends and distributions paid in respect of the Pledged Equity and all payments made in respect of the Pledged Notes, to the extent permitted in the Facility Agreement, and to exercise all voting and other rights with respect to the Investment Property; provided, that no vote shall be cast or other right exercised or action taken which would reasonably be expected to materially impair the Collateral or which would be inconsistent with or result in any violation of any provision of the Facility Agreement, this Agreement or any other Transaction Document.

15

(b) If an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of the Collateral Agent’s intent to exercise such rights to the relevant Grantor or Grantors, (i) the Collateral Agent for the ratable benefit of itself and each of the Lenders shall have the right to receive any and all cash dividends and distributions, payments or other Proceeds paid in respect of the Investment Property and make application thereof to the Secured Obligations in such order as the Collateral Agent may determine in its discretion, (ii) the Collateral Agent for the ratable benefit of itself and each of the Lenders shall have the right to cause any or all of the Investment Property to be registered in the name of the Collateral Agent for the ratable benefit of itself and each of the Lenders or their nominee and (iii) the Collateral Agent or its nominee may exercise (x) all voting and other rights pertaining to such Investment Property at any meeting of holders of the equity interests of the relevant Issuer or Issuers or otherwise (or by written consent) and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Investment Property as if they were the absolute owner thereof (including the right to exchange at its discretion any and all of the Investment Property upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other structure of any Issuer, or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Investment Property, and in connection therewith, the right to deposit and deliver any and all of the Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually received by it, but neither the Collateral Agent nor any Lender shall have any duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) After the occurrence and during the continuance of an Event of Default, each Grantor hereby authorizes and instructs each Issuer of any Investment Property pledged by such Grantor hereunder to (i) comply with any instruction received by it from the Collateral Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying and (ii) unless otherwise expressly permitted hereby, pay any dividends, distributions or other payments with respect to the Investment Property directly to the Collateral Agent for the ratable benefit of itself and each of the Lenders.

6.4 Proceeds to be Turned Over to the Collateral Agent. In addition to the rights of the Collateral Agent and the Lenders specified in Section 6.1 with respect to payments of Receivables, if an Event of Default shall occur and be continuing, all Proceeds received by any Grantor consisting of cash, checks and other cash equivalent items shall be held by such Grantor in trust for the Collateral Agent for the ratable benefit of itself and each of the Lenders, segregated from other funds of such Grantor, and shall, upon written request of the Collateral Agent, forthwith upon receipt by such Grantor, be turned over to the Collateral Agent for the ratable benefit of itself and each of the Lenders in the exact form received by such Grantor (duly indorsed by such Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent hereunder shall be held by the Collateral Agent in a collateral account maintained under its sole dominion and control. All Proceeds, while held by the Collateral Agent in any collateral account (or by such Grantor in trust for the Collateral Agent for the ratable benefit of itself and each of the Lenders) established pursuant hereto, shall continue to be held as collateral security for the Secured Obligations and shall not constitute payment thereof until applied as provided in Section 6.5.

16

6.5 Application of Proceeds. The Collateral Agent may apply all or any part of Proceeds from the sale of, or other realization upon, all or any part of the Collateral in payment of the Secured Obligations, as follows:

FIRST, to the payment of all reasonable and documented out-of-pocket costs and expenses incurred by the Collateral Agent (in its capacity as such hereunder or under any other Transaction Document) in connection with such collection, sale, foreclosure or realization or otherwise in connection with this Agreement, any other Transaction Document or any of the Obligations, including all court costs and the reasonable and documented fees and expenses of its agents and legal counsel, the repayment of all advances made by the Collateral Agent hereunder or under any other Transaction Document on behalf of any Grantor and any other reasonable and documented out-of-pocket costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Transaction Document;

SECOND, to the payment in full of all other Obligations (the amounts so applied to be distributed among the Lenders pro rata in accordance with the respective amounts of the Obligations owed to them on the date of any such distribution);

THIRD, to the Grantors, their successors or assigns, or as a court of competent jurisdiction may otherwise direct.

The Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement. Upon any sale of Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

6.6 Code and Other Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent and the Lenders may exercise, in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC or any other applicable law. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses (other than defense of payment), advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Collateral Agent or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery with assumption of any credit risk. Any Lender shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. Each Grantor further agrees, at the Collateral Agent’s request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 6.6, after deducting all reasonable documented out-of-pocket costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of any Lender hereunder, to the payment in whole or in part of the Secured Obligations, in such order as the

17

Collateral Agent may determine in its sole discretion, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, need the Collateral Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Collateral Agent or any Lender arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 calendar days before such sale or other disposition.

6.7 Registration Rights.

(a) If the Collateral Agent shall determine to exercise its right to sell any or all of the Pledged Equity pursuant to Section 6.6, and if in the opinion of the Collateral Agent it is necessary or advisable to have the Pledged Equity, or that portion thereof to be sold, registered under the provisions of the Securities Act, the relevant Grantor will use its commercially reasonable efforts to cause the Issuer thereof to (i) execute and deliver, and cause the directors and officers of such Issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or advisable to register the Pledged Equity, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its commercially reasonable efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Pledged Equity, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. Each Grantor agrees to cause such Issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the Collateral Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act.

(b) Each Grantor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Pledged Equity, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any of the Pledged Equity for the period of time necessary to permit the Issuer thereof to register such securities or other interests for public sale under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so.

(c) Each Grantor agrees to use its commercially reasonable efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Equity pursuant to this Section 6.7 valid and binding and in compliance with applicable law. Each Grantor further agrees that a breach of any of the covenants contained in this Section 6.7 will cause irreparable injury to the Collateral Agent and the Lenders, that the Collateral Agent and the Lenders have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 6.7 shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred under the Facility Agreement.

18

6.8 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Secured Obligations in full and the fees and disbursements of any attorneys employed by the Collateral Agent to collect such deficiency.

SECTION 7 MISCELLANEOUS.

7.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 6.6 of the Facility Agreement.

7.2 Notices. All notices, requests and demands to or upon the Collateral Agent or any Grantor hereunder shall be addressed to such party and effected in the manner provided for in Section 6.1 of the Facility Agreement and each Grantor hereby appoints Borrowers as its agent to receive notices hereunder.

7.3 Indemnification by Grantors.

(a) Each Grantor and each Guarantor shall, at all times, jointly and severally indemnify and hold the Collateral Agent and each other Lender harmless (the “Indemnity”) and each of their respective directors, partners, officers, employees, agents, counsel and advisors (each, an “Indemnified Person”) in connection with any losses, claims (including the reasonable and documented out-of-pocket attorneys’ fees incurred in defending against such claims), damages, liabilities, penalties, or other reasonable and documented out-of-pocket expenses arising out of this Agreement or the other Transaction Documents or the transactions contemplated hereby or thereby, which an Indemnified Person may incur or to which an Indemnified Person may become subject but (each, a “Loss”). The Indemnity shall not apply (i) to the extent that a court or arbitral tribunal of competent jurisdiction issues a final judgment that such Loss resulted from the gross negligence or willful misconduct of the Indemnified Person or (ii) to Losses that do not involve an act or omission by such Grantor, Guarantor or any of its Affiliates and that is brought by an Indemnified Person against any other Indemnified Person or (iii) in relation to any settlement effected by any Indemnified Person without the Borrower’s consent. The Indemnity is independent of and in addition to any other agreement of Grantors and Guarantors under any Transaction Document to pay any amount to the Collateral Agent or any Lender, and any exclusion of any obligation to pay any amount under this subsection shall not affect the requirement to pay such amount under any other section hereof or under any other agreement. For the avoidance on doubt, this Section 7.3 shall not apply to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(b) Promptly after receipt by an Indemnified Person under this Section 7.3 of notice of the commencement of any action (including any governmental action), such Indemnified Person shall, if a Loss in respect thereof is to be made against the indemnifying person under this Section 7.3, deliver to Grantors and Guarantors a written notice of the commencement thereof, and Borrower shall have the right to participate in, and, to the extent Grantors and Guarantors so desires, to assume control of the defense thereof with counsel mutually satisfactory to Grantors and Guarantors and the Indemnified Person, as the case may be.

(c) An Indemnified Person shall have the right to retain its own counsel with the reasonable and documented out-of-pocket fees and expenses to be paid by the indemnifying person, if, in the reasonable opinion of counsel for the Indemnified Person, the representation by such counsel of the Indemnified Person and Grantors and Guarantors would be inappropriate due to actual or potential differing interests between such Indemnified Person and any other party represented by such counsel in such proceeding. Grantors and Guarantors shall pay for only one separate legal counsel for the Indemnified Persons. The failure of an Indemnified Person to deliver written notice to the Grantors and Guarantors

19

within a reasonable time of the commencement of any such action shall not relieve the Grantors and Guarantors of any liability to the Indemnified person under this Section 7.3, except to the extent that Grantors and Guarantors are actually prejudiced in its ability to defend such action. The indemnification required by this Section 7.3 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable.

(d) The Grantors and Guarantors will not be liable under the Transaction Documents for any amount paid by an Indemnified Person to settle any claims or actions if the settlement is entered into without their consent (which consent shall not be unreasonably withheld, delayed or conditioned), provided that this section 7.3 shall not apply to those settlements where the Grantors and Guarantors were offered the ability to assume the defense of the action that directly and specifically related to the subject matter of such settlement and elected not to assume such defense.

(e) TO THE EXTENT PERMITTED BY LAW, NO PARTY HERETO SHALL ASSERT, AND EACH PARTY HERETO HEREBY WAIVES, ANY CLAIM AGAINST ANY INDEMNIFYING PARTY HEREUNDER, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGE (AS OPPOSED TO DIRECT OR ACTUAL DAMAGES) ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF THIS AGREEMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

7.4 Enforcement Expenses.

(c) The agreements in this Section 7.4 shall survive repayment of all (and shall be) Secured Obligations (and all commitments of Lenders, if any, to extend credit that would constitute Borrower Obligations have been terminated or have expired), any foreclosure under, or any modification, release or discharge of, any or all of the Collateral and termination of this Agreement.

7.5 Captions. Section captions used in this Agreement are for convenience only and shall not affect the construction of this Agreement.

7.6 Nature of Remedies. All Secured Obligations of each Grantor and rights of the Collateral Agent or any Lender expressed herein or in any other Transaction Document shall be in addition to and not in limitation of those provided by applicable law.

If any provision of this Agreement shall be invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. The Parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provision.

7.9 Entire Agreement. This Agreement, the other Transaction Documents and the Equity Documents contain the entire understanding of the Parties with respect to the matters covered thereby and supersede any and all other written and oral communications, negotiations, commitments and writings with respect thereto.

Exhibit 99.1

KemPharm Announces Debt Restructuring with Deerfield and Delaware Street Capital

Principal and Interest Payments on Outstanding Debt in Principal Amount of $77.7M Pushed to

March 31, 2021; Expected to Extend Cash Runway to New Maturity Date

KemPharm Will Host a Conference Call and Live Audio Webcast with Slide Presentation Today,

Wednesday, December 18, 2019, at 8:30 a.m. ET

Celebration, FL – December 18, 2019 – KemPharm, Inc. (Nasdaq: KMPH), a specialty pharmaceutical company engaged in the discovery and development of proprietary prodrugs, today announced its entry into a December 2019 Exchange Agreement and Amendment to Facility Agreement, Senior Secured Convertible Notes and Warrants (the December 2019 Exchange Agreement) with Deerfield (as defined below) and Delaware Street Capital (DSC, as further defined below). Under the December 2019 Exchange Agreement, the Company will effect a series of transactions, which, among other things, will push the principal and interest payments on outstanding debt in principal amount of $77.7 million to a new maturity date of March 31, 2021. The Company and Deerfield also agreed to certain adjustments to the September 2019 Exchange Agreement (as defined below) and the Company’s Facility Agreement with Deerfield dated June 2, 2014 (the Facility Agreement), each described in more detail below. In addition, the Company announced a prodrug discovery collaboration between Deerfield and KemPharm to employ the Company’s proprietary technology to potentially discover new product candidates for Deerfield or its affiliates.

“This restructuring transaction is the first step of an ongoing effort to improve the Company’s balance sheet by addressing our debt service and principal repayments due in 2020 and as a result extending our cash runway,” said LaDuane Clifton, KemPharm’s Chief Financial Officer. “The changes announced today add approximately $10. 4 million back to our operating forecast and extends our cash runway through March 31, 2021, which is past the potential approval date of our product candidate, KP415. We now move to the next step of finding a long-term solution to address our outstanding debt obligations,” Mr. Clifton concluded.

The Company also entered into an amendment of the September 2019 Exchange Agreement and Amendment to Facility Agreement with Deerfield, dated September 3, 2019 (the September 2019 Exchange Agreement), which adjusted the option exchange price to the greater of (i) the 15-day VWAP as of the date the option is exercised, or (ii) $0.60, compared to the previous price of $0.9494, added a limit of 28.4 million shares that can be issued, and removed the limit on the amount of nominal debt that can be exchanged under the agreement. As a result, the potential maximum dilution under the September 2019 Exchange Agreement remains unchanged from the original agreement.

Cowen served as KemPharm’s exclusive financial advisor in connection with the transactions contemplated under the December 2019 Exchange Agreement.

Drug Discovery Collaboration between Deerfield and KemPharm

KemPharm also announced a technology collaboration with Deerfield as part of the December 2019 Exchange Agreement. Under the December 2019 Exchange Agreement, Deerfield or its affiliates may identify up to two compounds that may have applications for new disease indications, and upon request and under mutually agreeable terms and conditions, KemPharm will utilize its proprietary technology to potentially discover new product candidates. If such effort is successful in discovering an acceptable product candidate, KemPharm and Deerfield may further collaborate to develop that product candidate subject to mutually agreeable terms and conditions. The discovery effort would seek to improve the profile of a selected drug candidate, possibly generate long-lived composition-of-matter patents, and seek to address unmet patient needs.

“We believe Deerfield has a history of supporting the development and commercialization of innovative drug therapies and is uniquely positioned through its network of affiliates to identify and evaluate the commercial potential of various product candidates across a broad spectrum of therapeutic areas,” said Dr. Travis Mickle, KemPharm’s Chief Executive Officer. “KemPharm is excited about the potential to collaborate with Deerfield and its affiliates to apply our LAT^TM (Ligand Activated Therapy) platform technology to unique product opportunities that could have the potential to address unmet patient needs.”

Details about the December 2019 Exchange Agreement, Amendments to the Facility Agreement and Amendments to the September 2019 Exchange Agreement:

The December 2019 Exchange Agreement was entered into by the Company and with Deerfield Private Design Fund III, L.P., and Deerfield Special Situations Fund, L.P. (together, Deerfield), and Delaware Street Capital Master Fund, L.P. (DSC, and together with Deerfield, the Holders). Under the December 2019 Exchange Agreement, the Company is issuing senior secured convertible notes in the aggregate principal of $71.4 million (the December 2019 Senior Notes) with a coupon of 6.75%, and interest added to principal through its maturity date of March 31, 2021, in exchange for the cancellation of an aggregate of $71.4 million of principal amount and accrued interest of the Company’s 5.50% Convertible Notes (the Prior Notes). Upon entering into the December 2019 Exchange Agreement, the Company agreed to pay the Holders $0.7 million, in the aggregate, which represent 50% of the accrued interest, as of December 18, 2019, on the Prior Notes owned by the Holders. The remainder of such interest is included in the principal amount of the December 2019 Senior Notes. Each December 2019 Senior Note is convertible at the option of the Holder into shares of the Company’s common stock at a price per share of $17.11, which represents the conversion price of the Prior Notes, subject to certain anti-dilution adjustments contained in the December 2019 Senior Notes.

In addition, amendments were made to the Facility Agreement such that the 6.75% senior secured note due 2020 to Deerfield in the aggregate amount of $7.0 million of principal and accrued interest (the Deerfield Note) was amended to, among other things, extend the maturity date of the Deerfield Note to March 31, 2021, and conform the definitions of “Eligible Market” and “Major Transactions” to the definition in the December 2019 Senior Notes. The conversion price for the Deerfield Note remains $5.85 per share, subject to adjustment on the same basis as the previously existing senior secured convertible notes, but subject to a floor price of $0.38.

As a result of the transactions contemplated under the December 2019 Exchange Agreement, the Holders have agreed to defer any payments due, including all future accrued interest, under the Prior Notes and Deerfield Note until March 31, 2021, and waived any put right under the Prior Notes, the Deerfield Note, of the warrant previously issued to Deerfield by the Company, with regard to any delisting of the Company’s common stock, until March 31 2021.

The Company also entered into an amendment of the September 2019 Exchange Agreement, which reflected that Deerfield may exchange its convertible debt for shares of either the Company’s common or preferred stock at a price equal to the greater of (i) the 15-day VWAP as of the date the option is exercised, or (ii) $0.60, compared to the previous price of $0.9494. The September 2019 Exchange Agreement was also amended to add a limit of 28.4 million shares that can be issued pursuant to the agreement, and to remove the $27.0 million limit on the amount of nominal debt that can be exchanged at Deerfield’s option under the agreement.
