EXECUTION VERSION 
 GUARANTY

 GUARANTY (this “Guaranty”), dated as of March 11, 2020, by each of the undersigned
Subsidiaries of the Borrower (as defined below) (each such Person, individually, a “Guarantor” and, collectively, the “Guarantors”) in favor of (i) Deerfield Partners, L.P., as agent (in such capacity, the
“Agent”) for its own benefit and the benefit of other Lenders, holders of other Obligations, holders of Convertible Notes and all Indemnified Persons (such persons, together with the Agent, the “Lender Parties”),
and (ii) the Lender Parties. 
 W I T N E S S E T H 

WHEREAS, reference is made to that certain Facility Agreement, dated as of March 11, 2020 (together with all exhibits and
schedules thereto and as may be amended, restated, modified and supplemented from time to time, the “Facility Agreement”), by and among the Borrower, the other Loan Parties thereto from time to time, the Lenders party thereto from
time to time and the Agent. Capitalized terms used herein, including in the introductory paragraph, and not defined herein shall have the meanings assigned to such terms in the Facility Agreement. 

WHEREAS, the Lenders have agreed, on a several but not joint basis, to extend certain term loans to the Borrower to provide
funds for the Borrower’s working capital and general corporate purposes, and pay a portion of the fees, costs and expenses related to the foregoing and entering into the Facility Agreement and providing the Loans contemplated thereby, in each
case subject to the terms and conditions set forth in the Facility Agreement. 
 WHEREAS, the Borrower has agreed to execute
and deliver Convertible Notes to each of the Lenders evidencing such Loans, subject to the terms and conditions set forth in the Facility Agreement; 

WHEREAS, each Guarantor acknowledges that it is an integral part of a consolidated enterprise and that it will receive direct
and indirect benefits from the Loans, the Facility Agreement and the Convertible Notes; 
 WHEREAS, the obligation of the
Lenders to make a Disbursement is conditioned upon, among other things, the execution and delivery by the Guarantors of a guaranty in the form hereof. As consideration therefor, and in order to induce the Lenders to make the Disbursement, the
Guarantors are willing to execute this Guaranty; 
 Accordingly, each Guarantor hereby agrees as follows: 

SECTION 1. Guaranty. 

(a) Each Guarantor (i) irrevocably, absolutely and unconditionally guarantees, jointly with the other
Guarantors and severally, as a primary obligor and not merely as a surety, the due and punctual payment when due (whether at the stated maturity, by required prepayment, by acceleration or otherwise) as well as the performance by the Borrower of all
Obligations (collectively, the “Guaranteed Obligations”), including all such Guaranteed Obligations which shall become due but for the operation of the Bankruptcy Code and (ii) agrees to pay any and all documented reasonable
costs and expenses (including reasonable counsel fees and expenses) incurred by the Agent and the Lender Parties in enforcing any rights under this Guaranty. Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed,
in whole or in part, without notice to or further assent from it, and that it will remain bound upon this Guaranty notwithstanding any extension or renewal of any Guaranteed Obligation. 

 (b) Upon the occurrence and during the continuance of an
Event of Default under Article 7 of the Facility Agreement and Section 2(c)(v)(C) of the Convertible Notes, the Required Lenders may direct the Agent to declare the Guaranteed Obligations due and payable hereunder, in which case, each Guarantor
shall be obligated to satisfy the Guaranteed Obligations within five (5) Business Days following receipt of notice from the Agent or the Required Lenders, and the Agent and the Lender Parties shall be entitled to enforce all Guaranteed
Obligations of the Guarantor hereunder after such due date. 
 SECTION 2. Guaranteed Obligations Not Affected. To the
fullest extent permitted by applicable Laws, each Guarantor waives presentment to, demand of payment from, and protest to, any Loan Party of any of the Guaranteed Obligations, and also waives notice of acceptance of this Guaranty, notice of protest
for nonpayment and all other notices of any kind. To the fullest extent permitted by applicable Laws, the obligations of each Guarantor hereunder shall not be affected by (a) the failure of the Agent or any other Lender Party to assert any
claim or demand or to enforce or exercise any right or remedy against any Loan Party under the provisions of the Facility Agreement, any other Facility Document or otherwise or against any other party with respect to any of the Guaranteed
Obligations or (b) any rescission, waiver (except the effect of any waiver obtained pursuant to Section 17(b)), amendment or modification of, or any release from, any of the terms or provisions of this Guaranty, any other Facility Document
or any other agreement, with respect to any Loan Party or with respect to the Guaranteed Obligations, or (c) the lack of legal existence of any Loan Party or legal obligation to discharge any of the Guaranteed Obligations by any Loan Party for
any reason whatsoever, including, without limitation, in any insolvency, bankruptcy or reorganization of any Loan Party. 

SECTION 3. [Reserved]. 

SECTION 4. Guaranty of Payment. Each of the Guarantors further agrees that this Guaranty constitutes a guaranty of
payment and performance when due of all Guaranteed Obligations (without limiting the application of Section 5 of this Guaranty) and not of collection and, to the fullest extent permitted by applicable Laws, waives any right
to require that any resort be had by the Agent or any other Lender Party to any assets of any Loan Party or to any other guarantor of all or part of the Guaranteed Obligations. Any payment required to be made by the Guarantors hereunder may be
required by the Agent or any other Lender Party on any number of occasions and shall be payable to the Agent, for the benefit of the Agent and the other Lender Parties, in the manner provided in the Facility Agreement. 

SECTION 5. Indemnification. Without limiting any of their indemnification obligations under the Facility Agreement or
the other Facility Documents, and without duplication of any indemnification provided for under the Facility Agreement or the other Facility Documents, each of the Guarantors, jointly and severally, shall indemnify the Lender Parties and each of
their Subsidiaries and Affiliates, and each of their respective stockholders, directors, officers, employees, agents, attorneys, and advisors (each such Person being called an “Indemnitee”), against, and hold each Indemnitee
harmless from, any and all damages, actual out-of-pocket losses, claims, actions, causes of action, settlement payments, obligations, liabilities and related expenses,
including the fees, charges and disbursements of any counsel for any Indemnitee, incurred, suffered, sustained or required to be paid by, or asserted against, any Indemnitee arising out of, in any way connected with, or as a result of, (i) the
execution or delivery of this Guaranty, the Facility Agreement or any other Facility Document or any other agreement or instrument contemplated hereby, the performance by the Guarantors of their respective obligations thereunder, or the consummation
of the transactions contemplated by the Facility Agreement and the other Facility Documents or any other transactions contemplated hereby or thereby, or (ii) any actual or prospective claim, litigation, investigation or proceeding relating to
or arising from any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided, however, such indemnity shall not, as to any Indemnitee, be available to
the extent that such 

  
 2 

 
losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Issuer or any other Loan Party against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other
Facility Document, if the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction. In connection with any indemnified claim hereunder, the Indemnitee
shall be entitled to select its own counsel and the Guarantors shall promptly pay the reasonable fees and expenses of such counsel. 

SECTION 6. No Discharge or Diminishment of Guaranty. The obligations of each Guarantor hereunder shall not be subject
to any reduction, limitation, impairment or termination for any reason (other than the payment in full of the Guaranteed Obligations), including any claim of waiver, release, surrender, alteration or compromise of any of the Guaranteed Obligations,
and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.
Without limiting the generality of the foregoing, the Guaranteed Obligations of each Guarantor hereunder shall not be discharged or impaired or otherwise affected by the failure of the Agent or any other Lender Party to assert any claim or demand or
to enforce any remedy under this Guaranty, the Facility Agreement, any other Facility Document or any other agreement, by any waiver or modification of any provision of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Guaranteed Obligations, or by any other act or omission that may or might in any manner or to any extent vary the risk of any Guarantor or that would otherwise operate as a discharge of any Guarantor as a matter of law or equity
(other than the payment in full of the Guaranteed Obligations). 
 SECTION 7. Defenses of Loan Parties Waived. To the
fullest extent permitted by applicable Law, each of the Guarantors waives any defense based on or arising out of any defense of any Loan Party or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation
from any cause of the liability of any Loan Party, other than the payment in full of the Guaranteed Obligations. Each Guarantor hereby acknowledges that the Agent and the other Lender Parties may, at their election, compromise or adjust any part of
the Guaranteed Obligations, make any other accommodation with any Loan Party, or exercise any other right or remedy available to them against any Loan Party, without affecting or impairing in any way the liability of any Guarantor hereunder except
to the extent that the Guaranteed Obligations have been paid in full. Pursuant to, and to the extent permitted by, applicable Laws, each of the Guarantors waives any defense arising out of any such election and waives any benefit of and right to
participate in any such foreclosure action, even though such election operates, pursuant to applicable Laws, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against any Loan Party, as
the case may be, or any security. Each Guarantor agrees that it shall not assert any claim in competition with the Agent or any other Lender Party in respect of any payment made hereunder in any bankruptcy, insolvency, reorganization, or any other
proceeding. 
 SECTION 8. Agreement to Pay; Subordination. In furtherance of the foregoing and not in limitation of
any other right that the Agent or any other Lender Party has at law or in equity against any Guarantor by virtue hereof, upon the failure of any Lender Party to pay any Guaranteed Obligation when and as the same shall become due, whether at
maturity, by acceleration, after notice of prepayment or otherwise, each of the Guarantors hereby promises to and will forthwith pay, or cause to be paid, to the Agent or such other Lender Party as designated thereby in cash the amount of such
unpaid Guaranteed Obligations. Upon payment by any Guarantor of any sums to the Agent or any other Lender Party as provided above, all rights of such Guarantor against any Lender Party arising as a result thereof by way of right of subrogation,
contribution, reimbursement, indemnity or otherwise shall in all respects be subordinate and junior in right of payment to the prior payment in full of all the Guaranteed Obligations. 

  
 3 

 
In addition, any Debt of the Borrower or any other Lender Party now or hereafter held by any Guarantor is hereby subordinated in right of payment to the prior payment in full of all of the
Guaranteed Obligations. Notwithstanding the foregoing, prior to the occurrence and continuance of an Event of Default, the Borrower or any other Loan Party may make payments to any Guarantor on account of any such Debt. After the occurrence and
during the continuance of an Event of Default, none of the Guarantors will demand, sue for, or otherwise attempt to collect any such Debt until the payment in full of the Guaranteed Obligations. If any amount shall erroneously be paid to any
Guarantor on account of (a) such subrogation, contribution, reimbursement, indemnity or similar right or (b) any such Debt of any Loan Party, such amount shall be held in trust for the benefit of the Lender Parties and shall forthwith be
paid to the Agent to be credited against the payment of the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of the Facility Agreement without affecting in any manner the liability of the Guarantor under the other
provisions of this Guaranty. 
 SECTION 9. Right of Set-off. Upon the
occurrence and during the continuance of any Event of Default, the Agent and the Lender Parties may, and are hereby authorized to, at any time and from time to time, without notice to the Guarantors (any such notice being expressly waived by
the Guarantors) and to the fullest extent permitted by Law, set-off and apply any Debt at any time owing by the Agent or any Lender Party to or for the credit or the account of the Guarantor against any and
all obligations of the Guarantors now or hereafter existing under this Guaranty or any other Facility Document, irrespective of whether the Agent or any Lender Party shall have made any demand under this Guaranty or any other Facility Document and
although such obligations may be contingent or unmatured. Each of the Agent and the Lender Parties agrees to notify the Guarantor promptly after any such set-off and application made by such Agent or such
Lender Party, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Agent and the Lender Parties under this Section 9 are in
addition to other rights and remedies (including, without limitation, other rights of set-off) which the Agent and the Lender Parties may have under this Guaranty or any other Facility Document in law or
otherwise. 
 SECTION 10. Limitation on Guaranty of Guaranteed Obligations. In any action or proceeding with respect
to any Guarantor involving any state corporate law, the Bankruptcy Code, or any other state or federal bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of such Guarantor under
Section 1 hereof would otherwise be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under said Section 1, then, notwithstanding any
other provision hereof to the contrary, the amount of such liability shall, without any further action by such Guarantor, any Lender Party, the Agent or any other Person, be automatically limited and reduced to the highest amount which is valid and
enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding. 
 SECTION 11.
Information. Each of the Guarantors assumes all responsibility for being and keeping itself informed of each Loan Party’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the
Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Agent or the other Lender Parties will have any duty to advise any of the Guarantors of information
known to it or any of them regarding such circumstances or risks. 
 SECTION 12. Termination. This Guaranty
(a) shall terminate when the principal of and interest on each Loan and all fees and other Guaranteed Obligations shall have been paid in full, and (b) shall continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any Guaranteed Obligation is rescinded or must otherwise be restored by any Lender Party or any Guarantor upon the bankruptcy or reorganization of any Loan Party or otherwise. 

  
 4 

 SECTION 13. Costs of Enforcement. Without limiting any of their
obligations under the Facility Agreement or the other Facility Documents, and without duplication of any fees or expenses provided for under the Facility Agreement or the other Facility Documents, the Guarantors, jointly and severally, agree to pay
on demand all expenses of the Lender Parties in connection with (i) the administration, negotiation, documentation or amendment of this Guaranty, and (ii) the Agent’s or any other Lender Party’s efforts to collect and/or to
enforce any of the Guaranteed Obligations of the Guarantors hereunder and/or to enforce any of the rights, remedies, or powers of the Agent or any other Lender Party against or in respect of the Guarantors (whether or not suit is instituted by or
against the Agent or any other Lender Party). 
 SECTION 14. [Reserved]. 

SECTION 15. [Reserved]. 

SECTION 16. Binding Effect; Several Agreement; Assignments. Whenever in this Guaranty any of the parties hereto is
referred to, such reference shall be deemed to include the successors and assigns of such party, and all covenants, promises and agreements by or on behalf of the Guarantors that are contained in this Guaranty shall bind and inure to the benefit of
each of the Guarantors and its respective successors and assigns. This Guaranty shall be binding upon each of the Guarantors and their respective successors and assigns, and shall inure to the benefit of the Agent and the other Lender Parties, and
their respective successors and assigns, except that no Guarantor shall have the right to assign or transfer its rights or obligations hereunder or any interest herein (and any such attempted assignment or transfer shall be void), except as
expressly permitted by this Guaranty or the Facility Agreement. If all of the capital stock of a Guarantor is sold, transferred or otherwise disposed of pursuant to a transaction permitted by the Facility Agreement, such Guarantor shall be released
from its obligations under this Agreement without further action. This Guaranty shall be construed as a separate agreement with respect to each Guarantor and may be amended, modified, supplemented, waived or released with respect to any Guarantor
without the approval of any other Guarantor and without affecting the obligations of any other Guarantor hereunder. 

SECTION 17. Waivers; Amendment. 

(a) The rights, remedies, powers, privileges, and discretions of the Agent hereunder and under applicable Law
(herein, the “Agent’s Rights and Remedies”) shall be cumulative and not exclusive of any rights or remedies which they would otherwise have. No delay or omission by the Agent in exercising or enforcing any of the Agent’s
Rights and Remedies shall operate as, or constitute, a waiver thereof. No waiver by the Agent of any Event of Default or of any default under any other agreement shall operate as a waiver of any other default hereunder or under any other agreement.
No single or partial exercise of any of the Agent’s Rights or Remedies, and no express or implied agreement or transaction of whatever nature entered into between the Agent and any Person, at any time, shall preclude the other or further
exercise of the Agent’s Rights and Remedies. No waiver by the Agent of any of the Agent’s Rights and Remedies on any one occasion shall be deemed a waiver on any subsequent occasion, nor shall it be deemed a continuing waiver. The
Agent’s Rights and Remedies may be exercised at such time or times and in such order of preference as the Agent may determine. The Agent’s Rights and Remedies may be exercised without resort or regard to any other source of satisfaction of
the Guaranteed Obligations. No waiver of any provisions of this Guaranty or any other Facility Document or consent to any departure by any Guarantor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b)
below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or 

  
 5 

 
demand on any Guarantor in any case shall entitle such Guarantor or any other Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

(b) Neither this Guaranty nor any provision hereof may be waived, amended or modified except pursuant to a
written agreement entered into between the Agent and the Guarantor or Guarantors with respect to whom such waiver, amendment or modification is to apply, subject to any consent required in accordance with Section 8.5 of the Facility Agreement.

 SECTION 18. Copies and Facsimiles. This instrument and all documents which have been or may be hereinafter
furnished by the Guarantors to any of the Agent may be reproduced by the Agent by any photographic, microfilm, xerographic, digital imaging, or other process. Any such reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made in the regular course of business). Any facsimile or other electronic transmission which bears proof of transmission
shall be binding on the party which or on whose behalf such transmission was initiated and likewise so admissible in evidence as if the original of such facsimile or other electronic transmission had been delivered to the party which or on whose
behalf such transmission was received. 
 SECTION 19. Governing Law. THIS GUARANTY SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF. 

SECTION 20. Notices. All communications and notices hereunder shall (except as otherwise expressly permitted herein) be
in writing and given as provided in Section 8.1 of the Facility Agreement, provided that communications and notices to the Guarantors may be delivered to the Borrower on behalf of each of the Guarantors. 

SECTION 21. Survival of Agreement; Severability. 

(a) All covenants, agreements, indemnities, representations and warranties made by the Guarantors herein and
in the certificates or other instruments delivered in connection with or pursuant to this Guaranty, the Facility Agreement or any other Facility Document shall be considered to have been relied upon by the Agent and the other Lender Parties and
shall survive the execution and delivery of this Guaranty, the Facility Agreement and the other Facility Documents, regardless of any investigation made by the Agent or any other Lender Party or on their behalf and notwithstanding that the Agent or
other Lender Party may have had notice or knowledge of any Default or Event of Default or incorrect representation or warranty at the time any credit is extended, and shall continue in full force and effect until terminated as provided in
Section 12 hereof. The provisions of Section 5 and Section 13 hereof shall survive and remain in full force and effect regardless of the repayment of the Guaranteed Obligations or the termination of this Guaranty or any provision
hereof. 
 (b) Any provision of this Guaranty held to be invalid, illegal or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof, and the invalidity of a
particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
 SECTION
22. Counterparts. This Guaranty may be executed in counterparts, each of which shall constitute an original but all of which, when taken together, shall constitute a single contract. 

  
 6 

 
Delivery of an executed counterpart of a signature page to this Guaranty by facsimile transmission shall be as effective as delivery of a manually executed counterpart of this Guaranty. 

SECTION 23. Rules of Interpretation. The rules of interpretation specified in Article 1 of the Facility Agreement
shall be applicable to this Guaranty. 
 SECTION 24. Jurisdiction; Consent to Service of Process.

(a) Each of the Guarantors agrees that any suit for the enforcement of this Guaranty or any other Note Document
may be brought in the courts of the State of New York sitting in New York County or any federal court sitting therein, as the Agent may elect in its sole discretion, and consents to the non-exclusive
jurisdiction of such courts. Each party to this Guaranty hereby waives any objection which it may now or hereafter have to the venue of any such suit or any such court or that such suit is brought in an inconvenient forum and agrees that a final
judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Nothing in this Guaranty shall affect any right that the Agent or any other
Lender Party may otherwise have to bring any action or proceeding relating to this Guaranty against a Guarantor or its properties in the courts of any jurisdiction. 

(b) Each of the Guarantors agrees that any action commenced by any Guarantor asserting any claim or
counterclaim arising under or in connection with this Guaranty or any other Facility Document shall be brought solely in a court of the State of New York sitting in New York County or any federal court sitting therein, as the Agent may elect in
their sole discretion, and consents to the exclusive jurisdiction of such courts with respect to any such action. 

(c) Each party to this Guaranty irrevocably consents to service of process in the manner provided for notices
in Section 20. Nothing in this Guaranty or any other Facility Document will affect the right of any party to this Guaranty to serve process in any other manner permitted by law. 

SECTION 25. Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OTHER NOTE DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY) AND WAIVES THE RIGHT TO ASSERT ANY SET-OFF, COUNTERCLAIM OR CROSS-CLAIM IN RESPECT OF, AND ALL STATUTES OF LIMITATIONS WHICH MAY BE RELEVANT TO, SUCH ACTION OR PROCEEDING; AND WAIVES DUE DILIGENCE,
DEMAND, PRESENTMENT AND PROTEST AND ANY NOTICES THEREOF AS WELL AS NOTICE OF NONPAYMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY
WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (B) ACKNOWLEDGES THAT THE AGENT AND THE OTHER LENDER PARTIES HAVE BEEN INDUCED TO ENTER INTO THE FACILITY DOCUMENTS BY, AMONG OTHER THINGS, THE WAIVERS AND
CERTIFICATIONS IN THIS SECTION 25. 
 SECTION 26. Subordination Agreement. This Guaranty (and all payment and
enforcement provisions with respect to the Guaranteed Obligations) is an unsecured obligation of the Guarantors and is 

  
 7 

 
subject to the terms of (1) a Subordination Agreement, dated as of March 11, 2020, by and among the guarantors, MidCap Financial Trust, a Delaware statutory trust (together with its
permitted successors and assigns), as administrative agent, the agent and the other parties named therein (as amended, restated, supplemented or otherwise modified from time to time, the “Subordination Agreement (Term Loan)”) and
(2) a Subordination Agreement, dated as of March 11, 2020, by and among the guarantors, Midcap Funding IV Trust, a Delaware statutory trust (together with its permitted successors and assigns), as administrative agent, the agent and the other
parties named therein (as amended, restated, supplemented or otherwise modified from time to time, the “Subordination Agreement (Revolving Loan)” and together with the Subordination Agreement (Term Loan), the “Subordination
Agreements”). In the event of any inconsistency between this note and the subordination agreements, the terms of the subordination agreements shall control.

(xv) “Rule 415” means Rule 415 under the Securities Act or any successor rule providing for the offering of securities on a
continuous basis. 
 2. REGISTRATION. 

a. MANDATORY REGISTRATION. (i) Following the Issuance Date, the Company shall prepare, and, on or prior to the applicable Filing
Deadline, file with the SEC a Registration Statement (the “Mandatory Registration Statement”) on Form S-3 (or, if Form S-3 is not then available, on such form of Registration Statement as is then
available to effect a Registration of the Registrable Securities, subject to the consent of the Investors, which consent shall not be unreasonably withheld) covering the resale of the Registrable Securities, which Registration Statement, to the
extent allowable under the Securities Act and the rules and regulations promulgated thereunder (including Rule 416), shall state that such Registration Statement also covers such indeterminate number of additional shares of Common Stock as may
become issuable pursuant to the Convertible Notes or the Conversion Shares to prevent dilution resulting from stock splits, stock dividends, stock issuances or similar transactions. The number of shares of Common Stock initially included in such
Registration Statement shall be no less than the aggregate number of Conversion Shares that are then issuable pursuant to the Convertible Notes, without regard to any limitations on the Investors’ ability to convert the Convertible Notes. Each
Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided to (and shall be subject to the approval, which shall not be unreasonably withheld or delayed, of) the
Investors and their counsel prior to its filing or other submission. 
 (ii) If for any reason, despite the Company’s use of its
reasonable best efforts to include all of the Registrable Securities in the Registration Statement filed pursuant to Section 2 (a)(i) above (and subject to Section 3(q) below), the SEC does not permit all of the Registrable Securities to
be included in, or for any other reason any Registrable Securities are not then included 

  
 -3- 

 
in, such Registration Statement, then the Company shall prepare, and, as soon as practicable but in no event later than the Additional Filing Deadline, file with the SEC an additional
Registration Statement covering the resale of all Registrable Securities not already covered by an existing and effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415. 

b. PIGGY-BACK REGISTRATIONS. If at any time prior to the expiration of the Registration Period (as hereinafter defined) the Company
shall determine (i) to file with the SEC a registration statement under the Securities Act relating to an offering for its own account or for the account of any other holder of its equity securities (other than securities being registered on
Form S-4 or Form S-8 or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit plans), and/or (ii) otherwise to effect an underwritten offering of any securities of the Company of a type included in a then effective Registration Statement, the
Company shall send to each Investor written notice of such determination, and if within fifteen (15) days after the effective date of such notice the Investor shall so request in writing, the Company shall include in such Registration Statement
and/or include in such underwritten offering, as applicable, all or any part of such Investor’s Registrable Securities that the Investor requests to be registered and/or included in the underwritten offering, as applicable, except that if in
connection with any underwritten offering for the account of the Company, the managing underwriter(s) thereof shall impose a limitation on the number of Registrable Securities which may be included in such offering because, in such
underwriter(s)’ reasonable judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall be obligated to include in such underwritten offering only such limited portion of
the Registrable Securities with respect to which the Investor has requested inclusion hereunder as the underwriter(s) shall permit; 

provided, however, that the Company shall not exclude any Registrable Securities unless the Company has first excluded all
outstanding securities to be sold for the accounts of any holders of the Company’s equity securities which are not entitled by contract to inclusion of such securities in an underwritten offering or are not entitled to pro rata inclusion with
the Registrable Securities; and 
 provided, further, however, that, after giving effect to the immediately preceding proviso,
any exclusion of Registrable Securities shall be made pro rata with holders of other securities having the contractual right to include such securities in such underwritten offering other than holders of securities entitled to inclusion of their
securities in such underwritten offering by reason of demand registration rights. No right to registration of Registrable Securities under this Section 2(b) shall be construed to limit any Registration required under Section 2(a) hereof.
If an Investor’s Registrable Securities are included in an underwritten offering pursuant to this Section 2(b), then such Investor shall, unless otherwise agreed by the Company, offer and sell such Registrable Securities in such
underwritten offering using the same underwriter or underwriters and, subject to the provisions of this Agreement, on the same terms and conditions as other shares of Common Stock included in such underwritten offering. Notwithstanding anything to
the contrary set forth herein, the rights of the Investors pursuant 

  
 -4- 

 
to this Section 2(b) shall only be available in the case of an underwritten offering or in the event the Company fails to timely file, obtain effectiveness or maintain effectiveness of any
Registration Statement to be filed pursuant to Section 2(a) in accordance with the terms of this Agreement. 
 3.  
OBLIGATIONS OF THE COMPANY. In connection with any registration of the Registrable Securities hereunder, the Company shall have the following obligations: 

a. The Company shall prepare promptly, and file with the SEC as soon as practicable after such registration obligation arises hereunder (but
in no event later than the applicable Filing Deadline), a Registration Statement with respect to the number of Registrable Securities provided in Section 2(a), as applicable, and thereafter use its reasonable best efforts to cause each such
Registration Statement relating to Registrable Securities to become effective as soon as possible after such filing, but in any event shall use its reasonable best efforts to cause each such Registration Statement relating to Registrable Securities
to become effective no later than the Registration Deadline, and shall thereafter use its reasonable best efforts to keep the Registration Statement current and effective pursuant to Rule 415 at all times after its effective date until such date as
is the earlier of (i) the date on which all of the Registrable Securities included in such Registration Statement have been sold and (ii) the date on which all of the Registrable Securities included in such Registration Statement (in the
opinion of counsel to the Investors) may be immediately sold to the public without registration or restriction (including without limitation as to volume by each holder thereof), and without compliance with any “current public information”
requirement, pursuant to Rule 144 under the Securities Act (the “Registration Period”), which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein), except for information provided in
writing by an Investor pursuant to Section 4(a), shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading. In the event
that Form S-3 is not available for the Registration of the resale of any Registrable Securities hereunder (but, for the avoidance of doubt, without in any way affecting the Company’s obligation to
register the resale of the Registrable Securities on such other form as is available, as provided in Section 2(a)), (i) the Company shall undertake to file, within twenty (20) days of such time as such form is available for such
Registration, a post-effective amendment to the Registration Statement then in effect, or otherwise file a Registration Statement on Form S-3, registering such Registrable Securities on Form S-3; provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement (or post-effective amendment) on Form S-3 covering such Registrable Securities has been declared effective by the SEC, and (ii) the Company shall provide that any Registration Statement on Form S-1 filed
hereunder shall incorporate documents by reference (including by way of forward incorporation by reference) to the maximum extent possible. 

b. The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to each Registration
Statement and the prospectus used in connection with each Registration Statement as may be necessary to keep each Registration Statement current and effective at all times during the Registration Period, and, during

  
 -5- 

 
the Registration Period, shall comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by each Registration Statement
until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement. In the event that on any Trading Day (as
defined below) (the “Registration Trigger Date”) the number of shares available under the Registration Statements filed pursuant to this Agreement is insufficient to cover all of the Registrable Securities issued or issuable pursuant to
the Convertible Notes, including any additional shares of Common Stock issued in connection with any anti-dilution provisions contained in the Convertible Notes, without giving effect to any limitations on the Investors’ ability to convert the
Convertible Notes, the Company shall amend the Registration Statements, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover the total number of Registrable Securities so issued or
issuable (without giving effect to any limitations on exercise contained in the Convertible Notes) as of the Registration Trigger Date as soon as practicable, but in any event within twenty (20) days after the Registration Trigger Date. The
Company shall use its reasonable best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof, but in any event the Company shall cause such amendment and/or new
Registration Statement to become effective within sixty (60) days of the Registration Trigger Date or as promptly as practicable in the event the Company is required to increase its authorized shares. “Trading Day” shall mean any day
on which the Common Stock is traded for any period on the NASDAQ Global Select Market (the “NasdaqGS”), or if not the NasdaqGS, the principal securities exchange or other securities market on which the Common Stock is then being traded.

 c. The Company shall furnish to each Investor and its legal counsel (i) promptly after the same is prepared and publicly
distributed, filed with the SEC or received by the Company, one copy of each Registration Statement and any amendment thereto, each preliminary prospectus and prospectus and each amendment or supplement thereto, and, in the case of a Registration
Statement referred to in Section 2(a), each letter written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration
Statement (other than any portion of any thereof which contains information for which the Company has obtained confidential treatment, which contains information for which the Company has redacted in compliance with Regulation S-K Item 601(b)(10),
which contains or reflects any material non-public information with respect to the Company or its securities or which relates to Company matters that are in the reasonable judgment of the Company not relevant
to the Investor’s interests with respect to the Registrable Securities), and (ii) such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as an Investor
may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor; provided that the Company may determine in its reasonable judgment to provide any such copies in electronic form only. The Company
will promptly notify each of the Investors by electronic mail of the effectiveness of each Registration Statement or any post-effective amendment. The Company will promptly respond to any and all comments received from the SEC as soon as practicable
and, as soon as practicable, but in no event later than three (3) business days, following the resolution or 

  
 -6- 

 
clearance of all SEC comments or, if applicable, following notification by the SEC that any such Registration Statement or any amendment thereto will not be subject to review, shall file a
request for acceleration of effectiveness of such Registration Statement to a time and date not later than two (2) business days after the submission of such request. No later than the first business day after such Registration Statement
becomes effective, the Company will file with the SEC the final prospectus included therein pursuant to Rule 424 (or successor thereto) under the Securities Act. 

d. The Company shall use its reasonable best efforts to (i) register and qualify, in any jurisdiction where registration and/or
qualification is required, the Registrable Securities covered by the Registration Statements under such other securities or “blue sky” laws of such jurisdictions in the United States as the Investors shall reasonably request,
(ii) prepare and file in those jurisdictions such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be reasonably necessary to maintain the effectiveness thereof during the
Registration Period, (iii) take such other actions as may be reasonably necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary
or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. 

e. As promptly as practicable after becoming aware of such event, the Company shall notify each Investor that holds Registrable Securities of
the happening of any event, of which the Company has knowledge, as a result of which the prospectus included in any Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make the statements therein not misleading, and promptly prepare a supplement or amendment to any Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such
supplement or amendment to each Investor as such Investor may reasonably request. 
 f. The Company shall use its reasonable best efforts to
prevent the issuance of any stop order or other suspension of effectiveness of any Registration Statement, and, if such an order is issued, to obtain the withdrawal of such order at the earliest possible moment and to notify each Investor that holds
Registrable Securities (and, in the event of an underwritten offering, the managing underwriters) of the issuance of such order and the resolution thereof. 

g. The Company shall permit a single firm of counsel designated by the Investors (“Legal Counsel”) to review such Registration
Statement and all amendments and supplements thereto (as well as all requests for acceleration or effectiveness thereof), a reasonable period of time prior to their filing with the SEC (not less than five (5) business days but not more than
eight (8) business days) and not file any documents in a form to which Legal Counsel reasonably objects and will not request acceleration of such Registration Statement without prior notice to Legal Counsel. 

  
 -7- 

 h. The Company shall hold in confidence and not make any disclosure of information
concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement
or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally
available to the public other than by disclosure in violation of this or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning any Investor is sought in or by a court or governmental body
of competent jurisdiction or through other means, give prompt notice to such Investor prior to making such disclosure, and allow such Investor, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order
for, such information. 
 i. The Company shall use its best efforts to cause all the Registrable Securities covered by each Registration
Statement to be listed on each securities exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange, and,
to arrange for at least two market makers to register with FINRA as such with respect to such Registrable Securities. 
 j. The Company
shall provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of the initial Registration Statement. 

k. The Company shall cooperate with each Investor that holds Registrable Securities being offered and the managing underwriter or underwriters
with respect to an applicable Registration Statement, if any, to facilitate the timely (i) preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be offered pursuant to such
Registration Statement, and enable such certificates to be registered in such names and in such denominations or amounts, as the case may be, or (ii) crediting of the Registrable Securities to be offered pursuant to a Registration Statement to
the applicable account (or accounts) with The Depository Trust Company through its Deposit/Withdrawal At Custodian (DWAC) system, in any such case as such Investor or the managing underwriter or underwriters, if any, may reasonably request. Within
three (3) business days after a Registration Statement which includes Registrable Securities becomes effective, the Company shall deliver, and shall cause legal counsel selected by the Company to deliver, to the transfer agent for the
Registrable Securities (with copies to each Investor) an appropriate instruction and an opinion of such counsel in the form required by the transfer agent in order to issue the Registrable Securities free of restrictive legends. 

l. At the reasonable request of an Investor, the Company shall prepare and file with the SEC such amendments (including post-effective
amendments) and supplements to a Registration Statement and any prospectus used in connection with the Registration Statement as may be necessary in order to change the plan of distribution set forth in such Registration Statement. 

m. The Company shall not, and shall not agree to, allow the holders of any securities of 

  
 -8- 

 
the Company to include any of their securities (other than Registrable Securities) in any Registration Statement filed pursuant to Section 2(a) hereof or any amendment or supplement thereto
under Section 3(b) hereof without the consent of Investors holding a majority-in-interest of the then outstanding Registrable Securities. In addition, the Company
shall not include any securities for its own account or the account of others in any Registration Statement filed pursuant to Section 2(a) hereof or any amendment or supplement thereto filed pursuant to Section 3(b) hereof without the
consent of Investors holding a majority-in-interest of the then outstanding Registrable Securities. 

n. Reserved. 
 o. The Company
shall comply with all applicable laws related to a Registration Statement and offering and sale of securities and all applicable rules and regulations of governmental authorities in connection therewith (including the Securities Act and the Exchange
Act and the rules and regulations promulgated by the SEC). 
 p. If required by the FINRA Corporate Financing Department, the Company shall
promptly effect a filing with FINRA pursuant to FINRA Rule 5110 (or successor thereto) with respect to the public offering contemplated by resales of securities under the Registration Statement (an “Issuer Filing”), and pay the filing fee
required by such Issuer Filing. The Company shall use its best efforts to pursue the Issuer Filing until FINRA issues a letter confirming that it does not object to the terms of the offering contemplated by the Registration Statement. 

q. If at any time the SEC advises the Company in writing that the offering of some or all of the Registrable Securities in a Registration
Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415, the Company shall use its reasonable best efforts to persuade the SEC that the offering contemplated by a Registration Statement is a bona fide
secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Investors is an “underwriter.” The Investors shall have the right to participate or have their respective counsel
participate in any meetings or discussions with the SEC regarding the SEC’s position and to comment or have their respective counsel comment on any written submission made to the SEC with respect thereto. No such written submission shall be
made to the SEC to which any Investor’s counsel reasonably objects. In the event that, despite the Company’s reasonable best efforts and compliance with the terms of this Section 3(q), the SEC refuses to alter its position, the
Company shall remove from the Registration Statement such portion of the Registrable Securities as the SEC requires in writing be removed therefrom. Any such cut-back imposed by the SEC as contemplated by this
Section 3(q) shall be imposed on a pro rata basis (based upon the Registrable Securities held by each of the Investors), first, to the Registrable Securities that are not Conversion Shares until all of such Registrable Securities are removed
from the Registration Statement, and only then to the Conversion Shares, unless otherwise required by the SEC. 
 r. Notwithstanding
anything to the contrary in Section 3(e), at any time after the effective date of the applicable Registration Statement, the Company may delay the disclosure of material non-public information concerning the Company the
disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best 

  
 -9- 

 
interest of the Company and is not, in the opinion of counsel to the Company, otherwise required (a “Grace Period”); provided, that the Company shall
(i) promptly notify the Investors in writing of the existence of material non-public information giving rise to a Grace Period (provided that in each notice the Company shall not disclose the content of
such material non-public information to any Investor unless otherwise requested in writing by such Investor) and the date on which the Grace Period will begin, and (ii) as soon as such date may be
determined, promptly notify the Investors in writing of the date on which the Grace Period ends; and, provided, further, that (A) no Grace Period shall exceed forty five (45) consecutive days, (B) during any three
hundred sixty five (365) day period, such Grace Periods shall not exceed an aggregate of seventy five (75) days, and (C) the first day of any Grace Period must be at least ten (10) business days after the last day of any prior
Grace Period (each Grace Period that satisfies all of the requirements of this Section 3(r) being referred to as an “Allowable Grace Period”). For purposes of determining the length of a Grace Period above,
the Grace Period shall begin on and include the date the Investors receive the notice referred to in clause (i) and shall end on and include the later of the date the Investors receive the notice referred to in clause (ii) and the date
referred to in such notice. The provisions of Section 3(e) hereof shall not be applicable during the period of any Allowable Grace Period, damages shall not accrue on any day during an Allowable Grace Period, and the
unavailability of a Registration Statement for resales of the Registrable Securities on any day during an Allowable Grace Period shall not constitute a “Registration Failure” (as defined in the Convertible Notes). Upon expiration of the
Grace Period, the Company shall again be bound by the first sentence of Section 3(e) with respect to the information giving rise thereto unless such material non-public information is
no longer applicable. 
 4. OBLIGATIONS OF THE INVESTOR. In connection with the registration of the Registrable Securities,
each Investor shall have the following obligations: 
 a. It shall be a condition precedent to the obligations of the Company to complete
the registration pursuant to this Agreement with respect to the Registrable Securities of an Investor that such Investor shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably
request. At least five (5) business days prior to the first anticipated filing date of a Registration Statement, the Company shall notify each Investor of the information the Company requires from such Investor. Any such information shall not
contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading. An Investor must provide such information to the Company at least two
(2) business days prior to the first anticipated filing date of such Registration Statement if such Investor elects to have any Registrable Securities included in the Registration Statement. 

b. Each Investor, by such Investor’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor’s election to exclude all of the Investor’s Registrable
Securities from 

  
 -10- 

 
such Registration Statement. 
 c. In the event of an underwritten offering pursuant
to Section 2(b) in which any Registrable Securities of any Investor are to be included, such Investor agrees to enter into and perform the Investor’s obligations under an underwriting agreement, in usual and customary form, including
customary indemnification and contribution obligations (as applicable to selling security holders generally), with the managing underwriter of such offering and take such other actions as are reasonably required in order to expedite or facilitate
the disposition of such Investor Registrable Securities. 
 d. Each Investor agrees that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 3(e) or 3(f), such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such
Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(e) or 3(f). 
 e. Each
Investor agrees that it will promptly notify the Company of any material changes in the information set forth in a Registration Statement furnished by or regarding such Investor, other than changes in the number of shares beneficially owned. 

5. REGISTRATION FAILURE. In the event of a Registration Failure (as defined in the Convertible Notes), the Investors shall be
entitled to damages and such other rights as set forth in the Convertible Notes and, subject to any applicable cure periods, all payments and remedies provided under the Facility Agreement upon the occurrence of an Event of Default. 

6. EXPENSES OF REGISTRATION. All reasonable expenses, other than underwriting discounts and commissions, incurred in connection
with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualification fees, printers and accounting fees, and the fees and disbursements of counsel for the Company
shall be borne by the Company. The Company shall also reimburse the Investors for the reasonable fees and disbursements of Legal Counsel in the aggregate amount up to $25,000 per registration in connection with registrations pursuant to
Section 2 or 3 of this Agreement. 
 7. INDEMNIFICATION. In the event any Registrable Securities are included in a
Registration Statement under this Agreement: 
 a. The Company will indemnify, hold harmless and defend (i) each Investor,
(ii) the directors, officers, partners, managers, members, employees, agents of each Investor, and each Person who controls any Investor within the meaning of the Securities Act or the Exchange Act, if any, (iii) any underwriter (as
defined in the Securities Act) for each Investor in connection with an underwritten offering pursuant to Section 2(b) hereof, and (iv) the directors, officers, partners, employees and each Person who controls any such underwriter within
the meaning of the Securities Act or the Exchange Act, if any (each, an “Indemnified Person”), against any joint or several losses, claims, damages, liabilities or expenses (collectively, together with actions, proceedings or inquiries by
any regulatory or self-regulatory organization, whether 

  
 -11- 

 
commenced or threatened, in respect thereof, “Claims”) to which any of them may become subject insofar as such Claims arise out of or are based upon: (i) any untrue statement or
alleged untrue statement of a material fact in any Registration Statement, or any amendment or supplement thereto, or any filing made under state securities laws as required hereby, or the omission or alleged omission to state therein a material
fact required to be stated or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, or any amendment or supplement thereto, or the omission
or alleged omission to state therein any material fact necessary to make the statements made therein, in the light of the circumstances under which the statements therein were made, not misleading; or (iii) any violation or alleged violation by
the Company of the Securities Act, the Exchange Act, any other law, including any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities (the matters in the foregoing clauses
(i) through (iii) being, collectively, “Violations”). The Company shall reimburse the Indemnified Person, promptly as such expenses are incurred and are due and payable, for any reasonable legal fees and other reasonable expenses
incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 7(a) shall not apply to a Claim arising out of or
based upon a Violation to the extent that such Violation occurs in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Indemnified Person expressly for use in connection with the preparation of
such Registration Statement or any such amendment thereof or supplement thereto, or (B) to any amounts paid in settlement of any Claim effected without the prior written consent of the Company, which consent shall not be unreasonably withheld
or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by any of the Investors pursuant to
Section 10. 
 b. Promptly after receipt by an Indemnified Person under this Section 7 of notice of the commencement of any action
(including any governmental action), such Indemnified Person shall, if a Claim in respect thereof is to be made against the Company under this Section 7, deliver to the Company a written notice of the commencement thereof, and the Company shall
have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Company and the Indemnified Person, as the case may be; 

provided, however, that an Indemnified Person shall have the right to retain its own counsel with the reasonable fees and
expenses to be paid by the Company, if, in the reasonable opinion of counsel for such Indemnified Person, the representation by such counsel of the Indemnified Person and the Company 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 Company shall pay for only one separate legal counsel for the Indemnified Persons, and such legal counsel shall be selected by the
Investors. The failure to deliver written notice to the Company within a reasonable time of the commencement of any such action shall not relieve the Company of any liability to the Indemnified Person under this Section 7, except to the extent
that the Company is actually prejudiced in its ability to defend such action, and shall not relieve the Company of any 

  
 -12- 

 
liability to the Indemnified Person otherwise than pursuant to this Section 7. The Company shall not, without the prior written consent of the Indemnified Persons, consent to entry of any
judgment or enter into any settlement or other compromise with respect to any Claim in respect of which indemnification or contribution may be or has been sought hereunder (whether or not any such Indemnified Party is an actual or potential party to
such action or claim) which does not include as an unconditional term thereof the giving by the claimant or plaintiff to the Indemnified Persons of a full release from all liability with respect to such Claim or which includes any admission as to
fault or culpability on the part of any Indemnified Person. The indemnification required by this Section 7 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as any expense, loss, damage
or liability is incurred. 
 c. Each Investor will indemnify, hold harmless and defend (i) the Company, and (ii) the directors,
officers, partners, managers, members, employees, or agents of the Company, if any (each, a “Company Indemnified Person”), against any Claims to which any of them may become subject insofar as such Claims arise out of or are based upon any
violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities, which occurs
due to the inclusion by the Company in a Registration Statement of false or misleading information about an Investor, where such information was furnished in writing to the Company by or on behalf of such Investor expressly for the purpose of
inclusion in such Registration Statement. Notwithstanding anything herein to the contrary, the indemnity agreement contained in this Section 7(c) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Investors, which consent shall not be unreasonably withheld or delayed; and provided, further, however, that an Investor shall be liable under this Section 7(c) for only that amount of a Claim as does not exceed
the net amount of proceeds received by such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. 

d. Promptly after receipt by a Company Indemnified Person under this Section 7 of notice of the commencement of any action (including any
governmental action), such Company Indemnified Person shall, if a Claim in respect thereof is to be made against any Investor under this Section 7, deliver to such Investor a written notice of the commencement thereof, and such Investor shall
have the right to participate in, and, to the extent such Investor so desires, to assume control of the defense thereof with counsel mutually satisfactory to such Investor and such Company Indemnified Person. 

8. CONTRIBUTION. If for any reason the indemnification provided for in Section 7(a) or 7(c) (as applicable) is unavailable
to an Indemnified Person or Company Indemnified Person (as applicable) or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the Indemnified
Person or Company Indemnified Person (as applicable) as a result of the Claim in such proportion as is appropriate to reflect the relative fault of the Indemnified Person or Company Indemnified Person (as applicable) and the indemnifying party
(provided that the relative fault of any Company Indemnified Person shall be deemed to include the fault of all other Company Indemnified Persons), as well as any other relevant equitable considerations.

  
 -13- 

 
No Person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any Person not guilty of such fraudulent
misrepresentation. In no event shall the contribution obligation of an Investor be greater in amount than the net amount of proceeds received by such Investor as a result of the sale of Registrable Securities giving rise to such contribution
obligation pursuant to the applicable Registration Statement (net of the aggregate amount of any damages or other amounts such Investor has otherwise been required to pay (pursuant to Section 7(c) or otherwise) by reason of such Investor’s
untrue or alleged untrue statement or omission or alleged omission). 
 9. REPORTS UNDER THE 1934 ACT. With a view to making
available to the Investors the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of the Company to the public without
registration, the Company agrees to: 
 a. make and keep public information available, as those terms are understood and defined in Rule
144; 
 b. file with the SEC in a timely manner all reports and other documents required of the Company under the Exchange Act so long as
the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and 

c. so long as any of the Investors owns Registrable Securities, promptly upon request, furnish to such Investor (i) a written statement
by the Company that it has complied with the reporting requirements of the Exchange Act as required for applicable provisions of Rule 144, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents
so filed by the Company and (iii) such other information as may be reasonably requested to permit such Investor to sell such Registrable Securities pursuant to Rule 144 without registration. 

10. ASSIGNMENT OF REGISTRATION RIGHTS. The rights under this Agreement shall be automatically assignable by each Investor to any
transferee of all or any portion of the Registrable Securities if: (i) such Investor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time
after such assignment, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to
which such registration rights are being transferred or assigned, and (iii) at or before the time the Company receives the written notice contemplated in clause (ii) of this sentence, the transferee or assignee agrees in writing with the
Company to be bound by all of the provisions contained herein as applicable to the Investors. In the event that the Company receives written notice from an Investor that it has transferred all or any portion of its Registrable Securities pursuant to
this Section, the Company shall have up to ten (10) days to file any amendments or supplements necessary to keep a Registration Statement current and effective pursuant to Rule 415, and the commencement date of any Registration Failure (as
defined in the Convertible Notes) or Event of Default (as defined in the Convertible Notes) under the Convertible Notes caused thereby will be extended by ten (10) days. Each Investor shall at all times comply with the

  
 -14- 

 
restrictions on transfer set forth in Section 13 of the Convertible Notes (to the extent applicable to such Investor), which provisions are hereby incorporated by reference and made a part
hereof. 
 11. AMENDMENT OF REGISTRATION RIGHTS. Provisions of this Agreement may be amended and the observance thereof may be
waived (either generally or in a particular instance and either retroactively or prospectively), only with written consent of the Company and the holders of a majority in interest of then-outstanding Registrable Securities. Any amendment or waiver
effected in accordance with this Section 11 shall be binding upon each of the Investors and the Company. 
 12. MISCELLANEOUS. 

a. A Person is deemed to hold, and be a holder of, shares of Common Stock or other Registrable Securities whenever such Person owns of record
or beneficially through a “street name” holder such shares of Common Stock or other Registrable Securities (or the Convertible Notes or other securities upon exercise, conversion or exchange of which such Registrable Securities are
directly or indirectly issuable, without giving effect to any limitations on exercise, conversion or exchange of the Convertible Notes or other securities), and solely for purposes hereof, Registrable Securities shall be deemed outstanding to the
extent they are directly or indirectly issuable upon exercise, conversion or exchange of the Convertible Notes or other outstanding securities, without giving effect to any limits on exercise, conversion or exchange of the Convertible Notes or other
securities. If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the
registered owner of such Registrable Securities (or the Convertible Notes or other securities upon exercise, conversion or exchange of which such Registrable Securities are directly or indirectly issuable). 

b. Any notices required or permitted to be given under the terms hereof shall be sent by certified or registered mail (return receipt
requested) or delivered personally or by courier (including a recognized overnight delivery service) or by electronic mail and shall be effective five days after being placed in the mail, if mailed by regular United States mail, or upon receipt, if
delivered personally or by courier (including a recognized overnight delivery service) or by electronic mail, in each case addressed to a party. The addresses for such communications shall be:

Each party shall provide notice to the other party of any change in address. 

c.   Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such
right or remedy, shall not operate as a waiver thereof. 
 d.   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 internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees
that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto 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, borough of Manhattan. 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 Agreement 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. If either party 

  
 -16- 

 
shall commence an action or proceeding to enforce any provision of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. 

e.   This Agreement, the Convertible Notes and the Facility Agreement (including all schedules and exhibits thereto) constitute the
entire agreement among the parties hereto with respect to the subject matter hereof. This Agreement, the Convertible Notes and the Facility Agreement (including all schedules and exhibits thereto) supersede all prior agreements and understandings
among the parties hereto with respect to the subject matter hereof. 
 f.   Subject to the requirements of Section 10 hereof,
this Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties hereto, and the provisions of Sections 7 and 8 hereof shall inure to the benefit of, and be enforceable by, each Indemnified Person
and Company Indemnified Person (as applicable). 
 g.   The headings in this Agreement are for convenience of reference only and
shall not limit or otherwise affect the meaning hereof. 
 h.   This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original but all of which shall constitute one and the same agreement. This Agreement, once executed by a party, may be delivered to the other party hereto by electronic transmission of a copy of this Agreement bearing
the signature of the party so delivering this Agreement. 
 i.   Each party shall do and perform, or cause to be done and
performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other parties may reasonably request in order to carry out the intent and accomplish the purposes
of this Agreement and the consummation of the transactions contemplated hereby. 
 j.     The Company acknowledges that
a breach by it of its obligations hereunder will cause irreparable harm to the Investors by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for breach of its
obligations hereunder will be inadequate and agrees, in the event of a breach or threatened breach by the Company of any of the provisions hereunder, that the Investors shall be entitled, in addition to all other available remedies in law or in
equity, to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, without the necessity of showing economic loss and without any bond or other
security being required. 
 k.   The language used in this Agreement will be deemed to be the language chosen by the parties to
express their mutual intent, and no rules of strict construction will be applied against any party. 
 l.     In the
event that any provision of this Agreement is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform
with such statute 

  
 -17- 

 
or rule of law. Any provision hereof which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision hereof. 

m. In the event an Investor shall sell or otherwise transfer any of such holder’s Registrable Securities, each transferee shall be
allocated a pro rata portion of the number of Registrable Securities included in a Registration Statement for such transferor. 
 n. There
shall be no oral modifications or amendments to this Agreement. This Agreement may be modified or amended only in writing. 
 o. The Company
shall not grant any Person any registration rights with respect to shares of Common Stock or any other securities of the Company other than registration rights that will not adversely affect the rights of the Investors hereunder (including by
limiting in any way the number of Registrable Securities that could be included in any Registration Statement pursuant to Rule 415) and shall not otherwise enter into any agreement that is inconsistent with the rights granted to the Investors
hereunder. 
 p. The obligations of each Investor hereunder are several and not joint with the obligations of any other Investor, and no
provision of this Agreement is intended to confer any obligations on any Investor vis-à-vis any other Investor. Nothing contained herein, and no action taken by
any Investor pursuant hereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with
respect to such obligations or the transactions contemplated herein. 
 q. Unless the context otherwise requires, (i) all references to
Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained in or attached to this Agreement, (ii) 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 (ii) the use of the word “including” in this Agreement shall be by way of example rather than limitation.
