duly authorized by the Board of Directors and all other necessary corporate action on the part of the Company. Assuming this Agreement constitutes the valid and binding obligation of the Purchaser, this Agreement is a valid and binding obligation of
the Company, enforceable against the Company in accordance with its terms, subject to the limitation of such enforcement by the effect of bankruptcy, insolvency, reorganization, receivership, conservatorship, arrangement, moratorium or other laws
affecting or relating to creditors’ rights generally or the rules governing the availability of specific performance, injunctive relief or other equitable remedies and general principles of equity, regardless of whether considered in a
proceeding in equity or at law (the “Enforceability Exceptions”). At the Closing, the Notes will be duly executed and delivered by the Company and will be a valid and binding obligation of the Company enforceable against the Company
in accordance with its terms, subject to the Enforceability Exceptions. 
 d.    General Solicitation; No
Integration. Neither the Company nor any other Person or entity authorized by the Company to act on its behalf has engaged in a general solicitation or general advertising (within the meaning of Regulation D of the Securities Act) of investors
with respect to offers or sales of the Notes. The Company has not, directly or indirectly, sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of, any security (as defined in the Securities Act) which, to its
knowledge, is or will be integrated with the Notes sold pursuant to this Agreement. 
 e.    Valid Issuance. The
Notes have been duly authorized by all necessary corporate action of the Company. When issued and sold against receipt of the consideration therefor, the Notes will be valid and legally binding obligations of the Company, enforceable in accordance
with their terms, subject to the limitation of such enforcement by the Enforceability Exceptions. The Company has available and has reserved for issuance the maximum number of shares of Company Common Stock initially issuable upon conversion of the
Notes if such conversion were to occur immediately following Closing (assuming fully physical share settlement). The Company Common Stock to be issued upon conversion of the Notes in accordance with the terms of the Notes has been duly authorized
and reserved for issuance, and when issued upon conversion of the Notes, all such Company Common Stock will be validly issued, fully paid and nonassessable and free of pre-emptive or similar rights. 

f.    Non-Contravention/No Consents. The execution, delivery and
performance of the Transaction Documents, the issuance of the shares of Company Common Stock upon conversion of the Notes in accordance with their terms and the consummation by the Company of the Transactions, does not conflict with, violate or
result in a breach of any provision of, or constitute a default under, or result in the termination of or accelerate the performance required by, or result in a right of termination or acceleration under, the certificate of incorporation or bylaws
of the Company, any “material contract” (as such term is defined in 

  
 10 

 
Item 601(b)(10) of Regulation S-K of the SEC) to which the Company or any of its Subsidiaries is a party and was filed or was required to be filed with the
Company Reports or any permit, government license, judgment, order, decree, ruling, injunction, statute, law, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, except as have been waived or consented to, and other
than in the cases of clauses (ii) and (iii) as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect and would not materially affect the Company’s ability to comply with its obligations under
the Notes or this Agreement. The Company has filed a Supplemental Application Review Form with NYSE with respect to the shares of Company Common Stock issuable upon conversion of the Notes. Assuming the accuracy of the representations of the
Purchaser set forth herein, other than (A) any required filings or approvals under the HSR Act or any foreign antitrust, competition or investment laws, requirements or regulations in connection with the issuance of shares of Company Common
Stock upon the conversion of the Notes or (B) any required filings pursuant to the Exchange Act or the rules of the SEC or NYSE, no consent, approval, order or authorization of, or registration, declaration or filing with, any Governmental
Entity is required on the part of the Company or any of its Subsidiaries in connection with the execution, delivery and performance by the Company of the Transaction Documents and the consummation by the Company of the Transactions, except for any
consent, approval, order, authorization, registration, declaration, filing, exemption or review, the failure of which to be obtained or made, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect and
would not materially affect the Company’s ability to comply with its obligations under the Notes or this Agreement. No vote or approval of the Company’s stockholders is or will be required under NYSE rules with respect to the issuance of
Company Common Stock contemplated hereunder or under the Notes.

 Section 3.02.    Representations and Warranties of the
Purchaser. The Purchaser represents and warrants to the Company, as of the date hereof and as of the Closing Date, as follows: 

a.    Organization; Ownership. The Purchaser is a limited liability company, duly organized, validly existing and
in good standing under the laws of the State of Delaware and has all requisite limited liability company power and authority to own, operate and lease its properties and to carry on its business as it is being conducted on the date of this
Agreement. 
 b.    Authorization; Sufficient Funds; No Conflicts. 

i    The Purchaser has full limited liability company power and authority to execute and deliver this Agreement and to
consummate the Transactions to which it is a party. The execution, delivery and performance by the Purchaser of this Agreement and the consummation of the Transactions to which it is a party have been duly authorized by all necessary limited
liability company action on behalf of the Purchaser. No other proceedings on the part of the Purchaser are necessary to authorize the execution, delivery and performance by the Purchaser of this Agreement and consummation of the Transactions. This
Agreement has been duly and validly executed and delivered by the Purchaser. Assuming this Agreement constitutes the valid and binding obligation of the Company, this Agreement is a valid and binding obligation of the Purchaser, enforceable against
the Purchaser in accordance with its terms, subject to the limitation of such enforcement by the Enforceability Exceptions. 

ii    At and immediately prior to the Closing, the Purchaser will have cash and equity capital commitments in excess of
the Purchase Price. 
 iii    The execution, delivery and performance of this Agreement by the Purchaser, the
consummation by the Purchaser of the Transactions to which it is a party and the compliance by the Purchaser with any of the provisions hereof and thereof will not conflict with, violate or result in a breach of any provision of, or constitute a
default under, or result in the termination of or accelerate the performance required by, or result in a right of termination or acceleration under, any provision of the Purchaser’s organizational documents, any mortgage, note, indenture, deed
of trust, lease, license, loan agreement or other agreement binding upon the Purchaser or any permit, government license, judgment, order, decree, ruling, injunction, statute, law, ordinance, rule or regulation applicable to the Purchaser or any of
its Affiliates, other than in the cases of clauses (B) and (C) as would not reasonably be expected to materially and adversely affect or delay the consummation of the Transactions to which the Purchaser is a party. 

c.    Consents and Approvals. No consent, approval, order or authorization of, or registration, declaration or
filing with, or exemption or review by, any Governmental Entity is required on the part of the Purchaser in connection with the execution, delivery and performance by the Purchaser of this Agreement and the consummation by the Purchaser of the
Transactions to which it is a party, except for any required filings or approvals under the HSR Act or any foreign antitrust, competition or investment laws, requirements or regulations in connection with the issuance of shares of Company Common
Stock upon the conversion of the Notes, any required filings pursuant to the Exchange Act or the rules of the SEC and any consent, approval, order, authorization, registration, declaration, filing, exemption or review, the failure of which to

  
 15 

 
be obtained or made, individually or in the aggregate, would not reasonably be expected to adversely affect or delay the consummation of the Transactions to which it is a party by the Purchaser.

 d.    Securities Act Representations. 

i    The Purchaser is an accredited investor (as defined in Rule 501 of the Securities Act) and is aware that the
offering and sale of the Notes is being made in reliance on a private placement exemption from registration under the Securities Act and may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from
registration is available. The Purchaser is acquiring the Notes (and any shares of Company Common Stock issuable upon conversion of the Notes) for its own account, and not with a view toward, or for sale in connection with, any distribution thereof
in violation of any federal or state securities or “blue sky” law, or with any present intention of distributing or selling such Notes (or any shares of Company Common Stock issuable upon conversion of the Notes) in violation of the
Securities Act. The Purchaser has sufficient knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of its investment in such Notes (and any shares of Company Common Stock issuable upon
conversion of the Notes) and is capable of bearing the economic risks of such investment. The Purchaser has been provided a reasonable opportunity to undertake and has undertaken such investigation and has been provided with and has evaluated such
documents and information as it has deemed necessary to enable it to make an informed and intelligent decision with respect to the execution, delivery and performance of this Agreement. 

ii    Neither the Purchaser nor any of its Affiliates is acting in concert, and neither the Purchaser nor any of its
Affiliates has any agreement or understanding, with any Person that is not an Affiliate of the Purchaser, and is not otherwise a member of a “group” (as such term is used in Section 13(d)(3) of the Exchange Act), with respect to the
Company or its securities. 
 iii    Except as disclosed in writing by the Purchaser to the Company prior to the entry
into this Agreement, neither the Purchaser, nor any person who through the Purchaser Beneficially Owns shares of Company Common Stock, has been or is subject to any disqualification event described in Rule 506(d) of Regulation D under the Securities
Act (a “Disqualification Event”) during the time periods specified in Rule 506(d) of Regulation D under the Securities Act. The Purchaser agrees to provide the Company with prompt written notice of the occurrence of any
Disqualification Event with respect to the Purchaser or any such Beneficial Owner. 
 e.    Brokers and Finders.
Neither the Purchaser nor any of its Affiliates has retained, utilized or been represented by, or otherwise become obligated to, any broker, placement agent, financial advisor or finder in connection with the transactions contemplated by this
Agreement whose fees the Company would be required to pay. 
 f.    Ownership of Shares. None of the Purchaser
or its Affiliates Beneficially Own any shares of Company Common Stock (without giving effect to the issuance of the Notes hereunder) except as disclosed in Schedule A hereto. Since January 1, 2021, none of the

  
 16 

 
Purchaser or its Affiliates has engaged in any hedge, swap, short sale or derivative transactions involving the Company Common Stock or other agreement or arrangement that transfers to any Third
Party, directly or indirectly, in whole or in part, any ownership of, or interests in, any shares of Company Common Stock. 

g.    Compliance with Applicable Law. Except as disclosed in writing by the Purchaser to the Company prior to
entry into this Agreement, the Purchaser has complied with, and is not in default or violation of, any law, statute, order, rule, regulation, policy or guideline of any Governmental Entity applicable to the Purchaser, except for such failures to
comply, defaults or violations that would not reasonably be expected to adversely affect or delay the consummation of the Transactions by the Purchaser. 

h.    No Additional Representations. 

i    The Purchaser acknowledges that the Company does not make any representation or warranty as to any matter whatsoever
except as expressly set forth in Section 3.01 and in any certificate delivered by the Company pursuant to this Agreement, and specifically (but without limiting the generality of the foregoing), that, except as expressly set forth in
Section 3.01 and in any certificate delivered by the Company pursuant to this Agreement, the Company makes no representation or warranty with respect to any matters relating to the Company, its business, financial condition, results of
operations, prospects or otherwise, any projections, estimates or budgets delivered or made available to the Purchaser (or any of its Affiliates, officers, directors, employees or other representatives) of future revenues, results of operations (or
any component thereof), cash flows or financial condition (or any component thereof) of the Company and its Subsidiaries or the future business and operations of the Company and its Subsidiaries, and the Purchaser has not relied on or been induced
by such information or any other representations or warranties (whether express or implied or made orally or in writing) not expressly set forth in Section 3.01 and in any certificate delivered by the Company pursuant to this Agreement. 

ii    The Purchaser has conducted its own independent review and analysis of the business, operations, assets,
liabilities, results of operations, financial condition and prospects of the Company and its Subsidiaries and acknowledges the Purchaser has been provided with sufficient access for such purposes. The Purchaser acknowledges and agrees that, except
for the representations and warranties expressly set forth in Section 3.01 and in any certificate delivered by the Company pursuant to this Agreement, no person has been authorized by the Company to make any representation or warranty relating
to itself or its business or otherwise in connection with the transactions contemplated hereby, and if made, such representation or warranty must not be relied upon by the Purchaser as having been authorized by the Company, and any estimates,
projections, predictions, data, financial information, memoranda, presentations or any other materials or information provided or addressed to the Purchaser or any of its Affiliates or representatives are not and shall not be deemed to be or include
representations or warranties of the Company unless any such materials or information are the subject of any express representation or warranty set forth in Section 3.01 of this Agreement and in any certificate delivered by the Company pursuant
to this Agreement. 
 iii    Notwithstanding the foregoing, nothing in this Section 3.02(h) shall be deemed to
limit the Purchaser’s or its Affiliates’ rights or remedies with respect to fraud.

each case which would reasonably be expected to result in a public announcement of such request or proposal. Notwithstanding the foregoing, KSP may initiate and engage in private, nonpublic discussions with, and submit confidential proposals to, the
board of directors or executive officers of the Company, in each case with respect to any the matters prohibited by Section 4.03; provided, that (i) any such proposal is conditioned on the written approval of the board of directors of the
Company, and (ii) any such discussions or proposal are not reasonably expected to require any public disclosure on the part of KSP, the Company or any of their respective subsidiaries or affiliates (whether controlled, controlling or under
common control). 

  
 20 

 b.    Notwithstanding anything to the contrary provided elsewhere
herein, none of the provisions of this Agreement shall in any way limit the activities of any Investor Party; provided, that such Investor Party (i) has not received material non-public information
regarding the Company and (ii) is not acting on behalf, or at the direction, of, or in concert with KSP, SCC, Purchaser or any of their subsidiaries. The Company acknowledges that employees of KSP and its affiliates (whether controlled,
controlling or under common control) may serve on the governing boards, advisory committees or similar committees of Investor Parties, and information shall not be deemed to have been received by any such Investor Party solely due to such
employee’s dual role (so long as such employee does not disclose such information to the Investor Party or its representatives). 

c.    For purposes of this Agreement, the term “Investor Parties” shall mean (i) KSP’s affiliates
(whether controlled, controlling or under common control) other than KSP, SCC, Purchaser and their subsidiaries, which affiliates of KSP are not acting on behalf, or at the direction, of or in concert with KSP, SCC, Purchaser or their subsidiaries,
(ii) employee benefit plans sponsored by KSP or any of its affiliates (whether controlled, controlling or under common control) (or a master trust holding the assets of such benefit plans), (iii) any family office that is an affiliate (whether
controlled, controlling or under common control) of Koch Industries, Inc. or any of its shareholders and/or any investment fund or vehicle advised by, or managed by, any such family office, (iv) any trust, foundation, partnership, or entity
created by or for Charles G. Koch and/or David H. or Julia F. Koch and/or any of their respective family members, (v) any entity 80% of whose voting equity interests is owned by one or more of such trusts, foundations, partnership, or entities,
and/or (vi) any other person or entity that invests money for or on behalf of any of the foregoing in its capacity as such. 

d.    The restrictions in Section 4.03(a) shall terminate automatically upon the earliest of the announcement by the
Company of a definitive agreement with respect to any Extraordinary Transaction that would directly or indirectly result in the acquisition of beneficial ownership by any person or group of 50% or more of the outstanding Company Common Stock, 50% or
more of the voting power of the outstanding Voting Stock or all or substantially all of the Company’s assets and the commencement of any tender or exchange offer (by a person other than the Purchaser or its Affiliates), which, if consummated,
would constitute an Extraordinary Transaction that would directly or indirectly result in the acquisition of beneficial ownership by any person or group of 50% or more of the outstanding Company Common Stock or 50% or more of the voting power of the
outstanding Voting Stock, where the Company files a Schedule 14D-9 (or any amendment thereto), other than a “stop, look and listen” communication by the Company pursuant to Rule 14d-9(f) promulgated under the Exchange Act, that does not recommend that the Company’s stockholders reject such tender or exchange offer. 

e.    Nothing in this Section 4.03 shall prevent any Purchaser Affiliate from making (x) any public or private
statement or announcement with respect to an Extraordinary Transaction that is publicly announced by the Company or a Third Party (and nothing in this Agreement shall prevent the Company from responding to such statements), (y) any factual statement
as required by applicable legal process, subpoena, or legal requirement or as part of a response to a request for information from any governmental authority with jurisdiction over the party from whom information is sought (so long as such request
did not arise as a result of discretionary acts by the Purchaser or any of its Affiliates) or (z) any confidential oral 

  
 21 

 
communication or proposal to management or the Board of Directors or affect the Purchaser’ s or the Purchaser Affiliates’ ability to hold the Notes or hold or vote any shares of Company
Common Stock, including the shares of Company Common Stock issuable or issued upon conversion of the Notes. 

f.    Notwithstanding anything in this Section 4.03 to the contrary, the prohibitions in this Section 4.03
shall immediately terminate without further force or effect and the Purchaser and the Purchaser Affiliates shall be released from compliance therewith if the Company institutes a voluntary proceeding, or becomes the subject of an involuntary
proceeding which involuntary proceeding is not dismissed within sixty (60) days, under any bankruptcy act, insolvency law or any law for the relief of debtors, has a receiver appointed to manage its affairs, which appointment is not dismissed,
vacated or stayed within sixty (60) days or executes a general assignment for the benefit of creditors. 

Section 4.04.    Securities Laws. The Purchaser acknowledges and agrees that as of the Closing Date, the Notes
(and the shares of Company Common Stock that are issuable upon conversion of the Notes) have not been registered under the Securities Act or the securities laws of any state and that they may be sold or otherwise disposed of only in one or more
transactions registered under the Securities Act and, where applicable, such laws, or as to which an exemption from the registration requirements of the Securities Act and, where applicable, such laws, is available, it is the responsibility of the
Purchaser to determine the applicable resale restrictions and to comply with such restrictions in connection with any resale, and the Company is required to file reports containing certain business and financial information with the SEC and may be
required to file a copy of this Agreement with the SEC, pursuant to the reporting requirements of the Exchange Act. The Purchaser acknowledges that the Purchaser has no right to require the Company or any of its Subsidiaries to register the Notes,
other than as set forth herein, or the shares of Company Common Stock that are issuable upon conversion of the Notes. 
 Additionally, for so long as a
holder of Notes or shares of Company Common Stock is subject to any transfer restrictions set forth in the Notes or this Agreement, the Notes will bear a legend in accordance with Section 2.05(c) of the Indenture, and the certificates or book
entry position representing such holder’s shares of Company Common Stock (as applicable) will bear or reflect a legend substantially similar to the following: 

“This security is subject to restrictions on transfer set forth in a Note Purchase Agreement, dated February 15, 2022 (as it may be
amended from time to time), by and among the Company and certain other parties thereto, copies of which are publicly filed or on file with the secretary of the issuer, and this security may not be offered, sold, pledged or otherwise transferred
except in compliance therewith.” 
 Section 4.05.    Lost, Stolen, Destroyed or Mutilated Securities.
Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any certificate for any security of the Company and, in the case of loss, theft or destruction, upon delivery of an undertaking by the holder
thereof to indemnify the Company (and, if requested by the Company, the delivery of an indemnity bond sufficient in the judgment of the Company to protect the Company from any loss it may suffer if a certificate is replaced), or, in the case of
mutilation, upon surrender and cancellation thereof, the Company will issue a new certificate or, at the Company’s option, a share ownership statement representing such securities for an equivalent number of shares or another security of like
tenor, as the case may be. 

  
 22 

 Section 4.06.    Antitrust Approval. The Company and the
Purchaser acknowledge that one or more filings under the HSR Act or foreign antitrust laws or foreign investment laws may be necessary in connection with the issuance of shares of Company Common Stock upon conversion of the Notes. The Purchaser will
promptly notify the Company if any such filing is required on the part of the Purchaser. The Company, the Purchaser and any other applicable Purchaser Affiliate will use reasonable best efforts to cooperate in timely making or causing to be made all
applications and filings under the HSR Act or any foreign antitrust or foreign investment requirements in connection with the issuance of shares of Company Common Stock upon conversion of Notes held by the Purchaser or any Purchaser Affiliate in a
timely manner and as required by the law of the applicable jurisdiction; provided that, notwithstanding anything in this Agreement, the Notes or the Indenture to the contrary, the Company shall not have any responsibility or liability for failure of
Purchaser or any of its Affiliates to comply with any applicable law. For as long as there are Notes outstanding and owned by Purchaser or its Affiliates, the Company shall as promptly as reasonably practicable provide (no more than four
(4) times per calendar year) such information regarding the Company and its Subsidiaries as the Purchaser may reasonably request in order to determine what foreign antitrust or foreign investment requirements may exist with respect to any
potential conversion of the Notes. Promptly upon request by the Purchaser, the Company will use best efforts to make all such filings and obtain all approvals and clearances as required under applicable antitrust laws or foreign investment laws in
connection with the issuance of the shares of Company Common Stock and investment in the shares of Company Common Stock upon conversion of the Notes. The Company and Purchaser will cooperate, provide all necessary information, and keep each other
fully apprised with respect to such filing and regulatory processes. The Purchaser shall be responsible for the payment of the filing fees associated with any such applications or filings. 

Section 4.07.    Certain Tax Matters. Notwithstanding anything herein to the contrary, the Company shall have
the right to deduct and withhold from any payment or distribution made with respect to the Notes (or the issuance of shares of Company Common Stock upon conversion of the Notes) such amounts as are required to be deducted or withheld with respect to
the making of such payment or distribution (or issuance) under any applicable Tax law. In the case of deemed dividends or amounts treated as original issue discount for tax purposes, any such withholding tax may be withheld from subsequent payments
on the Notes (or the issuance of shares of Company Common Stock upon conversion of the Notes, or dividends or any other amounts payable with respect to such shares). If the Company is required to remit any withholding tax payments to the applicable
Governmental Entity in respect of deemed dividends or amounts treated as original issue discount for tax purposes prior to any such subsequent payment or issuance, the Purchaser shall promptly upon notice reimburse the Company for the required
withholding tax payment. To the extent that any amounts are deducted or withheld as described in this Section 4.07, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in
respect of which such deduction or withholding was made. 

  
 23 

 Section 4.08.    Confidentiality. 

a.    The Purchaser acknowledges that Confidential Information (as defined below) has been and may in the future be made
available to it in connection with its investment in the Company. The Purchaser agrees that it shall, and shall cause any person to whom Confidential Information is disclosed pursuant to clause (i) below (collectively,
“Representatives”) to, keep the Confidential Information confidential and use the Confidential Information solely in connection with its investment in the Company. The Purchaser further acknowledges and agrees that such Confidential
Information may be, or contain, material non-public information under applicable law and such information may not be used to purchase, sell or trade in Company Securities (other than as permitted by applicable
law) or disclosed to any Affiliates or Third Parties, except as provided below. The Purchaser further acknowledges and agrees that it shall not disclose any Confidential Information to any person, except that Confidential Information may be
disclosed to any Purchaser Affiliate or any of the Purchaser’s or Purchaser Affiliates’ respective directors, officers, employees, agents, attorneys, advisors, accountants, or consultants who reasonably require access to such information
in connection with the Purchaser’s investment in the Company, including to the extent related to the tax treatment and tax structure of the Transactions, who in each case have been informed of the confidential nature of the Confidential
Information (provided that under no circumstances shall any Confidential Information be provided to any portfolio company of the Purchaser or to any portfolio company of any of their respective Affiliates); in the event and to the extent that
the Purchaser or any of its Representatives is required to disclose any Confidential Information by applicable law, legal process or other legal compulsion, whether or not in connection with any proceeding by or before a court of law or Governmental
Entity (provided that the Purchaser shall (to the extent not prohibited by applicable law) give the Company prompt written notice of such requirement (and in any event prior to any disclosure of Confidential Information in connection therewith) so
that the Company may seek an appropriate order or other remedy protecting such Confidential Information from disclosure or waive compliance with the terms of this Section 4.08 (and the Purchaser shall use reasonable efforts to cooperate with
the Company to obtain such protective order or other remedy, at the Company’ s expense)); to any person to whom the Purchaser in good faith is contemplating a transfer of any Notes or shares of Company Common Stock, provided that such transfer
would not be in violation of the provisions of this Agreement and such potential transferee is advised of the confidential nature of such information and agrees to be bound by a confidentiality agreement enforceable by the Company and consistent
with the provisions of this Section 4.08; or to any regulatory authority to which the Purchaser or any of its Affiliates is subject; provided that such authority is advised of the confidential nature of such information. The Purchaser shall be
responsible for any actions taken by any of its Representatives of the applicable provisions of this Section 4.08 as if the Purchaser had taken such actions. 

b.    For purposes hereof, “Confidential Information” shall mean any information concerning the Company
or any of its Subsidiaries or the business, products, markets, condition (financial or otherwise), operations, assets, liabilities, results of operations cash flows or prospects of the Company or any of its Subsidiaries (whether prepared by the
Company or otherwise) that is furnished or has been furnished (regardless of the manner in which it is or has been furnished) by or on behalf of the Company to the Purchaser or any of its Representatives at any time (whether before, on or after the
Closing Date) in connection with the Purchaser’s investment in the Company, and all notes, analyses, compilations, forecasts, studies, emails or other documents (in whatever form maintained) prepared by the Purchaser or any of its

  
 24 

 
Representatives that contain or reflect such information (in whole or in part); provided that the term “Confidential Information” does not include information that is or becomes
generally available to the public other than as a result of a disclosure by the Purchaser or its Representatives in violation of this Section 4.08, was within the Purchaser’s or its Representatives’ possession prior to it being
furnished to the Purchaser or its Representatives by or on behalf of the Company; provided that the source of such information was not known by the Purchaser to be bound by a confidentiality agreement or other contractual, legal or fiduciary
obligation of confidentiality with respect to such information, becomes available to the Purchaser or its Representatives on a non-confidential basis from a source other than the Company; provided that
such source is not known by the Purchaser to be bound by a confidentiality agreement or other contractual, legal or fiduciary obligation of confidentiality with respect to such information, or does not involve projections or strategic plans of the
Company and is independently developed by the Purchaser or its Representatives without reference to or the use of any Confidential Information. 

c.    Notwithstanding anything to the contrary contained herein, nothing contained herein shall prevent or restrict the
Purchaser’s or its Representatives’ use (subject, to the extent possible, to a protective order) of Confidential Information in connection with the assertion of any claim against, or the defense of any claim by, the Company or any of its
Subsidiaries, or the Purchaser or its Representatives from communicating with their respective investors to the extent reasonably required to fulfill their informational and reporting obligations to such persons; provided that the recipients
of such information are subject to a customary obligation to keep such information confidential, and if the provisions of Section 4.03(a) expire or terminate, neither this Section 4.08 nor any other provision hereof shall restrict or
prevent the Purchaser or its Affiliates from with respect to any Confidential Information, beginning 180 days after such information was received, using such Confidential Information in connection with acquiring, or agreeing, proposing, seeking or
offering to acquire, any securities or assets of the Company or any of its Subsidiaries pursuant to a tender offer, exchange offer, merger or other business combination transaction, or in connection with any of the other actions described in
Section 4.03(a), or publicly disclosing the history of discussions between the Purchaser and the Company to the extent reasonably necessary to comply with securities law disclosure obligations or other applicable law, regulation or securities
or securities exchange rules, subject, solely in the case of disclosures not involving matters referred to in the immediately preceding clause (A), to prior written notice to the Company and consideration in good faith of the Company’s
reasonable input on the content of such disclosures. 
 d.    The Purchaser and the Company hereby agree that this
Section 4.08 shall apply to all Confidential Information provided prior to the date hereof, including the fact and substance of the discussions and negotiations between the parties. 

Section 4.09.    NYSE Approval. The Company shall use its best efforts to cause the shares of Company Common
Stock issuable upon conversion of the Notes to be approved for listing on NYSE, subject to official notice of issuance. 

Section 4.10.    Authorized and Reserved Company Common Stock. For so long as any Notes are outstanding, the
Company shall cause the authorized capital stock of the Company to include a sufficient number of authorized but unissued shares of Company Common Stock to 

  
 25 

 
satisfy the conversion requirements of all Notes then outstanding (giving effect to any adjustment to the Conversion Rate (as defined in the Notes) pursuant to the Notes), and shall reserve and
keep available out of its authorized but unissued shares of Company Common Stock such number of shares thereof for issuance upon conversion of the Notes. 

Section 4.11.    Holder Consent Right Over Debt Incurrence. So long as at least $50 million aggregate
principal amount of the Notes remain outstanding and are held by Purchaser, the Company agrees that it shall not incur additional indebtedness without the consent of the holder of the Notes, which consent shall not be unreasonably withheld,
conditioned or delayed, other than: 
 a.    indebtedness incurred during any rolling
12-month period that does not exceed $50,000,000 individually or in the aggregate; and 

b.    indebtedness incurred in the ordinary course of business, including trade payables, refinancing indebtedness and
intercompany debt. 
 Article 5. Registration Rights 

Section 5.01.    Definitions. For purposes of this Article 5: 

a.    the term “Resale Registration Statement” shall mean any registration statement required to be
filed by Section 5.02 below, and shall include any preliminary prospectus, final prospectus, exhibit or amendment included in or relating to such registration statements; and 

b.    the term “Registrable Shares” means the Subject Securities; provided that any Subject Securities
will cease to be Registrable Securities upon the earliest of (A) when such Subject Securities have been sold or otherwise disposed of by the Purchaser and its Affiliates pursuant to an effective Resale Registration Statement or in compliance
with Rule 144, (B) when such Subject Securities cease to be outstanding or (C) the Subject Securities represent less than one percent (1%) of the outstanding shares of Company Common Stock; provided, further, that any securities that have
ceased to be Registrable Securities in accordance with the foregoing definition shall not thereafter become Registrable Securities and any securities that are issued or distributed in respect of securities that, at the time of such issuance or
distribution, have ceased to be Registrable Securities are not Registrable Securities 

Section 5.02.    Registration Procedures and Expenses. The Company shall: 

a.    use commercially reasonable efforts to file a Resale Registration Statement (the “Mandatory Registration
Statement”) with the SEC on or before the date 75 days following the Closing Date (the “Filing Date”) to register all of the Registrable Shares on Form S-3 under the Securities Act
(providing for shelf registration of such Registrable Shares under Commission Rule 415). In the event that Form S-3 is not available for the registration of the Registrable Shares, the Company shall register
the resale of the Registrable Shares on such other form as is available to the Company; 

  
 26 

 b.    use its commercially reasonable efforts to cause such Mandatory
Registration Statement to be declared effective within 30 days following the Filing Date (or, in the event the Staff reviews and has written comments to the Mandatory Registration Statement, within 120 days following the Filing Date) (the earlier of
the foregoing or the applicable date set forth in Section 5.02(h), the “Effectiveness Deadline”), such efforts to include, without limiting the generality of the foregoing, preparing and filing with the SEC any financial
statements or other information that is required to be filed prior to the effectiveness of such Mandatory Registration Statement 

c.    notwithstanding anything contained in this Agreement to the contrary, in the event that the SEC limits the amount
of Registrable Shares or otherwise requires a reduction in the number of Registrable Shares that may be included and sold by the Purchaser in the Mandatory Registration Statement (in each case, subject to Section 5.03), then the Company shall
prepare and file (i) within 10 Business Days of the first date or time that such excluded Registrable Shares may then be included in a Resale Registration Statement if the SEC shall have notified the Company that certain Registrable Shares were
not eligible for inclusion in the Resale Registration Statement or (ii) in all other cases, within 20 days following the date that the Company becomes aware that such additional Resale Registration Statement is required (the “Additional
Filing Date”), a Resale Registration Statement (any such Resale Registration Statement registering such excluded Registrable Shares, an “Additional Registration Statement” and, together with the Mandatory Registration
Statement, a “Resale Registration Statement”) to register any Registrable Shares that have been excluded (or, if applicable, the maximum number of such excluded Registrable Shares that the Company is permitted to register for resale
on such Additional Registration Statement consistent with SEC guidance), if any, from being registered on the Mandatory Registration Statement; 

d.    use its commercially reasonable efforts to cause any such Additional Registration Statement to be declared
effective as promptly as practicable following the Additional Filing Date, such efforts to include, without limiting the generality of the foregoing, preparing and filing with the SEC any financial statements or other information that is required to
be filed prior to the effectiveness of any such Additional Registration Statement; 
 e.    prepare and file with the
Commission such amendments and supplements to such Resale Registration Statements and the prospectus used in connection therewith as may be necessary to keep such Resale Registration Statements continuously effective and free from any material
misstatement or omission to state a material fact therein until termination of such obligation as provided in Section 5.06 below, subject to the Company’s right to suspend pursuant to Section 5.05; 

f.    furnish to the Purchaser such number of copies of prospectuses in conformity with the requirements of the
Securities Act and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Shares by the Purchaser; 

g.    file such documents as may be required of the Company for normal securities law clearance for the resale of the
Registrable Shares in such states of the United States as may be reasonably requested by the Purchaser and use its commercially reasonable efforts to 

  
 27 

 
maintain such blue sky qualifications during the period the Company is required to maintain effectiveness of the Resale Registration Statements; provided, however, that the
Company shall not be required in connection with this Section 5.02(g) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented;

 h.    upon notification by the SEC that the Resale Registration Statement will not be reviewed or is not subject to
further review by the Commission, the Company shall within three Business Days following the date of such notification request acceleration of such Resale Registration Statement (with the requested effectiveness date to be not more than two Business
Days later); 
 i.    upon notification by the Commission that that the Resale Registration Statement has been declared
effective by the Commission, the Company shall file the final prospectus under Rule 424 of the Securities Act (“Rule 424”) within the applicable time period prescribed by Rule 424; 

j.    advise the Purchaser promptly: 

i    of the effectiveness of the Resale Registration Statement or any post-effective amendments thereto; 

ii    of any request by the SEC for amendments to the Resale Registration Statement or amendments to the prospectus or
for additional information relating thereto; 
 iii    of the issuance by the SEC of any stop order suspending the
effectiveness of the Resale Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable Shares for offering or sale in any jurisdiction, or the initiation of any
proceeding for any of the preceding purposes; and 
 iv    of the existence of any fact and the happening of any event
that makes any statement of a material fact made in the Resale Registration Statement, the prospectus and amendment or supplement thereto, or any document incorporated by reference therein, untrue, or that requires the making of any additions to or
changes in the Resale Registration Statement or the prospectus in order to make the statements therein not misleading; 

k.    cause all Registrable Shares to be listed on each securities exchange, if any, on which equity securities by the
Company are then listed; and 
 l.    bear all expenses in connection with the procedures in paragraphs
(a) through (l) of this Section 5.02 and the registration of the Registrable Shares on such Resale Registration Statement and the satisfaction of the blue sky laws of such states. 

Section 5.03.    Rule 415 Cutback. 

If at any time the staff of the SEC (“Staff”) takes the position that the offering of some or all of the Registrable Shares
in a Registration Statement is not eligible to be made on 

  
 28 

 
a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires the Purchaser to be named as an “underwriter,” the Company shall (in consultation
with legal counsel to the lead Purchaser) use its commercially reasonable efforts to persuade the SEC that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the
issuer” as defined in Rule 415 and that none of the Purchaser is an “underwriter.” In the event that, despite the Company’s commercially reasonable efforts and compliance with the terms of this Section 5.03, the Staff
refuses to alter its position, the Company shall (i) remove from the Registration Statement such portion of the Registrable Shares (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the
registration and resale of the Registrable Shares as the Staff may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall
not agree to name the Purchaser as an “underwriter” in such Registration Statement without the prior written consent of the Purchaser. No liquidated damages shall accrue as to any Cut Back Shares until such date as the Company is able to
effect the registration of such Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date” of such Cut Back Shares). From and after the Restriction Termination Date applicable to any Cut
Back Shares, all of the provisions of this Article 5 shall again be applicable to such Cut Back Shares; provided, however, that (x) the Filing Deadline for the Registration Statement including such Cut Back Shares shall be 10
Business Days after such Restriction Termination Date, and (y) the Effectiveness Deadline with respect to such Cut Back Shares shall be the 90th day immediately after the Restriction
Termination Date or the 120th day if the Staff reviews such Registration Statement (but in any event no later than three Business Days from the Staff indicating it has no further comments on
such Registration Statement). 
 Section 5.04.    Indemnification. 

a.    The Company agrees to indemnify and hold harmless the Purchaser and its affiliates, partners, members, officers,
directors, agents and representatives, and each Person, if any, who controls the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 the Exchange Act (each, a “Purchaser Party” and collectively
the “Purchaser Parties”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages or liabilities (collectively, “Losses”) to which they may become subject (under the
Securities Act or otherwise) insofar as such Losses (or actions or proceedings in respect thereof) arise out of, or are based upon, any material breach of this Agreement by the Company or any untrue statement or alleged untrue statement of a
material fact contained in the Resale Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which
they were made, not misleading or arise out of any failure by the Company to fulfill any undertaking included in the Resale Registration Statement and the Company will, as incurred, reimburse the Purchaser Parties for any legal or other expenses
reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such Loss arises out of, or is
based upon: (i) an untrue statement or omission or alleged untrue statement or omission made in such Resale Registration Statement in reliance upon and in conformity with written information furnished to the Company by or on behalf of the
Purchaser specifically for use in preparation of the Resale Registration Statement; or (ii) any 

  
 29 

 
breach of this Agreement by the Purchaser; provided further, however, that the Company shall not be liable to any Purchaser Party (or any partner, member, officer, director or
controlling Person of the Purchaser) to the extent that any such Loss is caused by an untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus if either (i) (A) the Purchaser failed to send or
deliver a copy of the final prospectus with or prior to, or the Purchaser failed to confirm that a final prospectus was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the
sale by the Purchaser to the Person asserting the claim from which such Loss resulted and (B) the final prospectus corrected such untrue statement or omission, (ii) (X) such untrue statement or omission is corrected in an amendment or
supplement to the prospectus and (Y) having previously been furnished by or on behalf of the Company with copies of the prospectus as so amended or supplemented or notified by the Company that such amended or supplemented prospectus has been
filed with the Commission, in accordance with Rule 172 of the Securities Act, the Purchaser thereafter fails to deliver such prospectus as so amended or supplemented, with or prior to or the Purchaser fails to confirm that the prospectus as so
amended or supplemented was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the sale by the Purchaser to the Person asserting the claim from which such Loss resulted or
(iii) the Purchaser sold Registrable Shares in violation of the Purchaser’s covenants contained in this Agreement. 

b.    The Purchaser agrees to indemnify and hold harmless the Company and its officers, directors, affiliates, agents and
representatives and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each a “Company Party” and collectively the
“Company Parties”), from and against any Losses to which the Company Parties may become subject (under the Securities Act or otherwise), insofar as such Losses (or actions or proceedings in respect thereof) arise out of,
or are based upon, any material breach of this Agreement by the Purchaser or untrue statement or alleged untrue statement of a material fact contained in the Resale Registration Statement (or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading in each case, on the effective date thereof), if, and only to the extent, such untrue
statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of the Purchaser specifically for use in preparation of the Resale Registration Statement,
and the Purchaser will reimburse each Company Party for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that in no event
shall any indemnity under this Section 5.04(b) be greater in amount than the dollar amount of the net proceeds received by the Purchaser upon its sale of the Registrable Shares included in the Registration Statement giving rise to such
indemnification obligation. 
 c.    Promptly after receipt by any indemnified Person of a notice of a claim or the
beginning of any action in respect of which indemnity is to be sought against an indemnifying Person pursuant to this Section 5.04, such indemnified Person shall notify the indemnifying Person in writing of such claim or of the commencement of
such action, and, subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified Person and such indemnifying Person shall have been notified thereof, such

  
 30 

 
indemnifying Person shall be entitled to participate therein, and, to the extent that it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified
Person. After notice from the indemnifying Person to such indemnified Person of its election to assume the defense thereof, such indemnifying Person shall not be liable to such indemnified Person for any legal expenses subsequently incurred by such
indemnified Person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate in the reasonable judgment of the indemnified Person for the
same counsel to represent both the indemnified Person and such indemnifying Person or any affiliate or associate thereof, the indemnified Person shall be entitled to retain its own counsel at the expense of such indemnifying Person; provided,
further, that no indemnifying Person shall be responsible for the fees and expense of more than one separate counsel for all indemnified parties. The indemnifying party shall not settle an action without the consent of the indemnified party, which
consent shall not be unreasonably withheld. 
 d.    If after proper notice of a claim or the commencement of any
action against the indemnified party, the indemnifying party does not choose to participate, then the indemnified party shall assume the defense thereof and upon written notice by the indemnified party requesting advance payment of a stated amount
for its reasonable defense costs and expenses, the indemnifying party shall advance payment for such reasonable defense costs and expenses (the “Advance Indemnification Payment”) to the indemnified party. In the event that the
indemnified party’s actual defense costs and expenses exceed the amount of the Advance Indemnification Payment, then upon written request by the indemnified party, the indemnifying party shall reimburse the indemnified party for such
difference; in the event that the Advance Indemnification Payment exceeds the indemnified party’s actual costs and expenses, the indemnified party shall promptly remit payment of such difference to the indemnifying party 

e.    If the indemnification provided for in this Section 5.04 is held by a court of competent jurisdiction to
be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law
contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other, as well as any other relevant equitable considerations; provided, that in no event shall any contribution by an indemnifying party hereunder be greater in amount than the dollar amount of the proceeds received by such
indemnifying party upon the sale of such Registrable Shares. 
 Section 5.05.    Prospectus Suspension. 

The Purchaser acknowledges that there may be times when the Company must suspend the use of the prospectus forming a part of the Resale
Registration Statement until such time as an amendment to the Resale Registration Statement has been filed by the Company and declared effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission
pursuant to the Exchange Act. The Purchaser hereby covenants that it will not sell any Registrable Shares pursuant to said prospectus during the period commencing at the time at which the Company gives the Purchaser notice of the suspension of the
use of said prospectus and ending at the time the Company gives the Purchaser notice that the Purchaser 

  
 31 

 
may thereafter effect sales pursuant to said prospectus; provided, that such suspension periods shall in no event exceed 30 days in any 12 month period and that, in the good faith judgment of the
Company’s board of directors, the Company would, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development, a potentially significant transaction or event
involving the Company, or any negotiations, discussions, or proposals directly relating thereto, in either case the disclosure of which would reasonably be expected to have a material adverse effect upon the Company or its stockholders. 

Section 5.06.    Termination of Obligations. 

The obligations of the Company pursuant to Section 5.02 hereof shall cease and terminate, with respect to any Registrable
Shares, upon the earlier to occur of (a) such time such Registrable Shares have been resold, or (b) such time as such Registrable Shares no longer remain Registrable Shares pursuant to Section 5.01(b) hereof. 

Section 5.07.    Reporting Requirements. 

a.    With a view to making available the benefits of certain rules and regulations of the Commission that may at any
time permit the sale of the Shares to the public without registration or pursuant to a registration statement on Form S-3, the Company agrees to: 

i    make and keep public information available, as those terms are understood and defined in Rule 144; 

ii    file with the Commission in a timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and 
 iii    so long as the Purchaser owns Registrable Shares, furnish to the
Purchaser upon request (A) a written statement by the Company as to whether it is in compliance with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, or whether it is qualified as a registrant whose securities
may be resold pursuant to Commission Form S-3, (B) 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 (C) such other
information as may be reasonably requested to permit the Purchaser to sell such securities pursuant to Rule 144. 

Section 5.08.    Blue Sky. 

The Company shall obtain and maintain all necessary blue sky law permits and qualifications, or secured exemptions therefrom, required by any
state for the offer and sale of Registrable Shares.

Section 6.03.    Entire Agreement; Third-Party Beneficiaries; Amendment. This Agreement, together with the
other Transaction Documents, sets forth the entire agreement 

  
 33 

 
between the parties hereto with respect to the Transactions, and supersedes all prior agreements and understandings, both oral and written, among the parties and their respective Affiliates with
respect to the subject matter hereof and thereof, and is not intended to and shall not confer upon any person other than the parties hereto, their successors and permitted assigns any rights or remedies hereunder, provided that
Section 6.12 shall be for the benefit of and fully enforceable by each of the Specified Persons. Any provision of this Agreement may be amended, waived or modified in whole or in part at any time by an agreement in writing between the parties
hereto executed in the same manner as this Agreement. No failure on the part of any party to exercise, and no delay in exercising, any right shall operate as a waiver thereof nor shall any single or partial exercise by any party of any right
preclude any other or future exercise thereof or the exercise of any other right. 

Section 6.04.    Counterparts. This Agreement may be executed in one or more counterparts, each of which shall
be deemed to constitute any original, but all of which together shall constitute one and the same document. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format”
(“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document will have the same effect as physical delivery of the paper document bearing the original signature.

 Section 6.05.    Public Announcements. The initial press release related to this Agreement and the
Transactions shall be a joint press release to be agreed upon by the Company and Purchaser. Thereafter, either party may issue or make one or more press releases or public announcements related to this Agreement or the Transactions (in which case
the other party shall (to the extent permitted by applicable law) have the right to review and reasonably comment on such press release or announcement prior to issuance, distribution or publication); provided that the foregoing shall not
apply to any press release or other public announcement to the extent that it contains substantially the same factual information related to this Agreement and the Transactions as previously communicated publicly by one or more of the parties in
accordance with this Section 6.05. Without limiting the foregoing, the Company may file this Agreement with the SEC and may provide information about the subject matter of this Agreement in connection with equity or debt issuances, share
repurchases, or marketing, informational or reporting activities. 
 Section 6.06.    Expenses. Except as
otherwise expressly provided herein, each party hereto shall bear its own costs and expenses (including attorneys’ fees) incurred in connection with this Agreement and the Transactions. Notwithstanding the foregoing, from and after the date of
this Agreement, at any time and from time to time, the Purchaser shall have the right to request that the Company reimburse all documented out-of-pocket expenses
(including attorneys’ fees) incurred by the Purchaser or its Affiliates in connection with their evaluation of the Company and the transactions contemplated pursuant to this Agreement, including all expenses related to the due diligence review
and the structuring, drafting, negotiating and entry into this Agreement and the other Transaction Agreements, up to seventy-five thousand dollars ($75,000) in the aggregate, which the Company shall do promptly and in any event within three
(3) Business Days of the Closing Date or earlier termination, provided however, that the Company will be required to reimburse such expenses to the Purchaser only to the extent that doing so does not require the Company to obtain shareholder
approval pursuant to Section 312.03 

  
 34 

 
of the NYSE Listed Company Manual; provided that no duplicative adjustments shall be made with respect to such matter made in connection with the Securities Purchase Agreement dated the
date hereof between the Company and the Purchaser. 
 Section 6.07.    Successors and Assigns. Except as
otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the Company’s successors and assigns and Purchaser’s successors and assigns, and no other person; provided that neither
the Company nor the Purchaser may assign its respective rights or delegate its respective obligations under this Agreement, whether by operation of law or otherwise, without the prior written consent of the other party, and any assignment by the
Company or the Purchaser in contravention hereof shall be null and void; provided that any Affiliate of the Purchaser who executes and delivers a Joinder pursuant to a Permitted Transfer of any Notes or shares of Company Common Stock pursuant
to Section 4.02(a)(i) shall be deemed a Purchaser hereunder and have all the rights and obligations of a Purchaser, and if the Company consolidates or merges with or into any Person and the Company Common Stock is, in whole or in part,
converted into or exchanged for securities of a different issuer in a transaction that does not constitute a Change in Control, then as a condition to such transaction the Company will cause such issuer to assume all of the Company’s rights and
obligations under this Agreement in a written instrument delivered to the Purchaser. For the avoidance of doubt, no Third Party to whom any of the Notes or shares of Company Common Stock are transferred shall have any rights or obligations under
this Agreement. 
 Section 6.08.    Governing Law; Jurisdiction; Waiver of Jury Trial. 

a.    THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICTS OF LAWS PROVISIONS THEREOF). 

b.    Each of the Company and the Purchaser irrevocably consents and agrees that any legal action, suit or proceeding
against it with respect to obligations, liabilities or any other matter arising out of or in connection with this Agreement may be brought in the courts of the State of New York or the courts of the United States located in the Borough of Manhattan,
New York City, New York and hereby irrevocably consents and submits to the non-exclusive jurisdiction of each such court in personam, generally and unconditionally with respect to any action, suit or
proceeding for itself in respect of its properties, assets and revenues. 
 c.    Each of the Company and the Purchaser
irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with this
Agreement brought in the courts of the State of New York or the courts of the United States located in the Borough of Manhattan, New York City, New York and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in
any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. 

  
 35 

 Section 6.09.    Severability. If any provision of this
Agreement is determined to be invalid, illegal or unenforceable, the remaining provisions of this Agreement shall remain in full force and effect provided that the economic and legal substance of, any of the Transactions is not affected in
any manner materially adverse to any party. In the event of any such determination, the parties agree to negotiate in good faith to modify this Agreement to fulfill as closely as possible the original intent and purpose hereof. To the extent
permitted by law, the parties hereby to the same extent waive any provision of law that renders any provision hereof prohibited or unenforceable in any respect. 

Section 6.10.    Specific Performance. The parties agree that irreparable damage would occur in the event that
any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each party agrees that in the event of any breach or threatened breach by any other party of any covenant or
obligation contained in this Agreement, the non-breaching party shall be entitled (in addition to any other remedy that may be available to it, whether in law or equity) to obtain a decree or order of specific
performance to enforce the observance and performance of such covenant or obligation, and an injunction restraining such breach or threatened breach. Each of the parties agrees that it will not oppose the granting of an injunction, specific
performance and other equitable relief on the basis that any other party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. Any party seeking an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction. 

Section 6.11.    Headings. The headings of Articles and Sections contained in this Agreement are for reference
purposes only and are not part of this Agreement. 

Section 6.12.    Non-Recourse. This Agreement may only be enforced
against, and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby may only be brought against the entities that are expressly named as parties hereto and their respective
successors and assigns (including any Person that executes and delivers a Joinder). Except as set forth in the immediately preceding sentence, no past, present or future director, officer, employee, incorporator, member, partners, stockholder,
Affiliate, agent, attorney, advisor or representative of any party hereto or of any Affiliate of a party hereto (collectively, the “Specified Persons”) shall have any liability for any obligations or liabilities of any party hereto
under this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby.

period (and any extensions thereof) imposed under the HSR Act shall have been obtained, shall have been received or shall have terminated or expired, as the case may be.

 3.2    Representations, Warranties and
Covenants of the Purchaser. The Purchaser hereby represents, warrants and covenants to the Company as of the Closing: 

(a)    The Purchaser has all requisite legal and corporate or other power and capacity and has taken all requisite
corporate or other action to execute and deliver this Agreement, to purchase the Shares and to carry out and perform all of its obligations under this Agreement; and (b) this Agreement constitutes the legal, valid and binding obligation of the
Purchaser, enforceable against the Purchaser in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization or similar laws relating to or affecting the enforcement of creditors’ rights generally
and (ii) as limited by equitable principles generally. 
 (b)    At the time the Purchaser was offered the
Shares, it was: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the
Securities Act. The Purchaser is aware of the Company’s business affairs and financial condition and has had access to and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the
Shares. The Purchaser has such business and financial experience as is required to give it the capacity to protect its own interests in connection with the purchase of the Shares. The Purchaser acknowledges that it has had the opportunity to review
the Company’s filings with the Commission and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the
offering of the Shares and the merits and risks of investing in the Shares and (ii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make
an informed investment decision with respect to the investment. 
 (c)    The Purchaser is purchasing the Shares
for its own account, for investment purposes only, and not with a present view to, or for, resale, distribution or fractionalization thereof, in whole or in part (within the meaning of the Securities Act) in violation of the Securities Act. The
Purchaser understands that its acquisition of the Shares has not been registered under the Securities Act or registered or qualified under any state securities law in reliance on specific exemptions therefrom, which exemptions may depend upon, among
other things, the bona fide nature of the Purchaser’s investment intent as expressed herein. The Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or
otherwise acquire or take a pledge of) the Shares except in compliance with the Securities Act and the rules and regulations promulgated thereunder. 

(d)    The Purchaser represents and acknowledges that is has not been solicited to offer to purchase or to
purchase any Shares by means of any general solicitation or advertising within the meaning of Regulation D under the Securities Act. 

  
 7 

 (e)    The Purchaser represents that it is not a Person of the
type described in Section 506(d) of Regulation D under the Securities Act that would disqualify the Company from engaging in a transaction pursuant to Section 506 of Regulation D under the Securities Act. 

(f)    The Purchaser understands that the Shares being offered and sold to it in reliance on specific exemptions
from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties, agreements,
acknowledgements and understandings of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire the Shares. The Purchaser further acknowledges and understands that the
Shares may not be resold or otherwise transferred except in a transaction registered under the Securities Act or unless an exemption from such registration is available. 

(g)    The Purchaser understands that nothing in this Agreement or any other materials presented to the Purchaser
in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Purchaser has consulted such legal, tax and investment advisors and made such investigations as the Purchaser, in its sole discretion, has deemed
necessary or appropriate in connection with its purchase of the Shares. The Purchaser hereby acknowledges and agrees that it has independently evaluated the merits of its decision to purchase the Shares. 

(h)    Dispositions. 

(i)    The Purchaser will not, prior to the effectiveness of the Resale Registration Statement (as defined below),
if then prohibited by law or regulation other than pursuant to an available exemption under the Securities Act: (i) sell, offer to sell, solicit offers to buy, dispose of, loan, pledge or grant any right with respect to (collectively, a
“Disposition”) the Shares; or (ii) engage in any hedging or other transaction which is designed or could reasonably be expected to lead to or result in a Disposition of the Shares by the Purchaser or an affiliate. 

(ii)    As of the Closing Date, the Purchaser has not directly or indirectly, nor has any Person acting on behalf
of or pursuant to any understanding with the Purchaser, engaged in any purchases or sales of the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) since the time that the Purchaser was
first contacted by the Company or any other Person regarding the transactions contemplated hereby, except pursuant to the transactions contemplated by the Note Purchase Agreement (the “Note Purchase Agreement”) or that certain Securities
Purchase Agreement, by and between the Company and the Purchaser, dated as of June 29, 2021. The Purchaser covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with it will engage in any purchases or
sales of the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) prior to the time that the transactions contemplated by this Agreement are publicly disclosed. 

(iii)    The Purchaser has independently evaluated the merits of its decision to purchase Shares pursuant to this
Agreement. The Purchaser understands that nothing in this Agreement or any other materials presented to the Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. 

  
 8 

 (iv)    The Purchaser will hold in confidence all information
concerning this Agreement and the sale and issuance of the Shares until the Company has made a public announcement concerning this Agreement and the sale and issuance of the Shares, which shall be made not later than 9:00 am New York time on the
first Trading Day immediately after the signing of this Agreement. 
 (v)    The Purchaser understands that no
United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or endorsement of the Shares. 

(i)    Legend. 

(i)    The Purchaser understands that the Shares shall bear a restrictive legend in substantially the following
form (and a stop transfer order may be placed against Transfer of the certificates for the Shares): 
 “THE SECURITIES REPRESENTED BY
THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR IN ANY OTHER JURISDICTION. THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR TRANSFERRED
IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.” 

(ii)    The Company shall, at its sole expense, upon appropriate notice from the Purchaser stating that
Registrable Shares have been sold pursuant to an effective Registration Statement, timely prepare and deliver certificates or book-entry shares representing the Shares to be delivered to a transferee pursuant to the Registration Statement, which
certificates or book-entry shares shall be free of any restrictive legends and in such denominations and registered in such names as the Purchaser may request. Further, the Company shall, at its sole expense, cause its legal counsel or other counsel
satisfactory to the transfer agent: (i) while the Registration Statement is effective, to issue to the transfer agent a “blanket” legal opinion to allow sales without restriction pursuant to the effective Registration Statement, and
(ii) provide all other opinions as may reasonably be required by the transfer agent in connection with the removal of legends. The Purchaser may request that the Company remove, and the Company agrees to authorize the removal of, the legend
from such Shares, following the delivery by the Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such Shares: (i) following any sale of such Shares pursuant to Rule 144, (ii) if such Shares
are eligible for sale under Rule 144(b)(1), or (iii) following the time that the Registration Statement is declared effective. If a legend removal request is made pursuant to the foregoing, the Company will, no later than three Trading Days
following the delivery by the Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such Shares (or a request for legend removal, in the case of Shares issued in book-entry form), deliver or cause to be
delivered to the Purchaser a certificate representing such Shares that is free from all restrictive legends or an 

  
 9 

 
equivalent book-entry position, as requested by the Purchaser. Certificates for Shares free from all restrictive legends may be transmitted by the Company’s transfer agent to the Purchaser
by crediting the account of the Purchaser’s prime broker with the Depository Trust Company (“DTC”) as directed by the Purchaser. The Company warrants that the Shares shall otherwise be freely transferable on the books
and records of the Company as and to the extent provided in this Agreement. If the Purchaser effects a Transfer of the Shares in accordance with this Section 3.2(i)(ii), the Company shall permit the transfer and shall
promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by the Purchaser to effect such transfer. The Purchaser hereby
agrees that the removal of the restrictive legend pursuant to this Section 3.2(i)(ii) is predicated upon the Company’s reliance that the Purchaser will sell any such Shares pursuant to either the registration
requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom. 

(j)    Immediately prior to the Closing, the Purchaser, together with its affiliates and any other Persons acting
as a group together with the Purchaser and any of its affiliates, beneficially owned the number of shares of Common Stock (before giving effect to Common Stock beneficially owned as a result of Note Purchase Agreement dated the date hereof between
the Parties hereto) set forth on the Purchaser’s signature page attached hereto (as such ownership is calculated pursuant to the rules of the NYSE). 

(k)    If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Code), the
Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Shares or any use of this Agreement, including (a) the legal requirements
within its jurisdiction for the purchase of the Shares, (b) any foreign exchange restrictions applicable to such purchase or acquisition, (c) any government or other consents that may need to be obtained, and (d) the income tax and
other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Shares. The Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any
applicable securities or other laws of the Purchaser’s jurisdiction. 
  

	4.	 REGISTRATION RIGHTS 

4.1    Definitions. For the purpose of this Section 4: 

(a)    the term “Resale Registration Statement” shall mean any registration statement
required to be filed by Section 4.2 below, and shall include any preliminary prospectus, final prospectus, exhibit or amendment included in or relating to such registration statements; and 

(b)    the term “Registrable Shares” means the Shares; provided, however, that a
security shall cease to be a Registrable Share upon the earliest to occur of the following: (i) a Resale Registration Statement registering such security under the Securities Act has been declared or becomes effective and such security has been
sold or otherwise transferred by the holder thereof pursuant to and in a manner contemplated by such effective Resale Registration Statement, (ii) such security is sold pursuant to Rule 144 under circumstances in which any legend borne by such
security relating to restrictions on transferability thereof, under the Security Act or otherwise, is removed by the Company, (iii) such security is eligible to be sold pursuant to Rule 144 without

  
 10 

 
condition or restriction, including without any limitation as to volume of sales, and without the Holder complying with any method of sale requirements or notice requirements under Rule 144, or
(iv) such security shall cease to be outstanding following its issuance. 
 4.2    Registration
Procedures and Expenses. The Company shall: 
 (a)    use commercially reasonable efforts to file a Resale
Registration Statement (the “Mandatory Registration Statement”) with the Commission on or before the date 75 days following the Closing Date (the “Filing Date”) to register all of the Registrable
Shares on Form S-3 under the Securities Act (providing for shelf registration of such Registrable Shares under Commission Rule 415). In the event that Form S-3 is not
available for the registration of the Registrable Shares, the Company shall register the resale of the Registrable Shares on such other form as is available to the Company; 

(b)    use its commercially reasonable efforts to cause such Mandatory Registration Statement to be declared
effective within 30 days following the Filing Date (or, in the event the Staff reviews and has written comments to the Mandatory Registration Statement, within 120 days following the Filing Date) (the earlier of the foregoing or the applicable date
set forth in Section 4.2(h), the “Effectiveness Deadline”), such efforts to include, without limiting the generality of the foregoing, preparing and filing with the Commission any financial
statements or other information that is required to be filed prior to the effectiveness of such Mandatory Registration Statement; 

(c)    notwithstanding anything contained in this Agreement to the contrary, in the event that the Commission
limits the amount of Registrable Shares or otherwise requires a reduction in the number of Registrable Shares that may be included and sold by the Purchaser in the Mandatory Registration Statement (in each case, subject to
Section 4.3), then the Company shall prepare and file (i) within 10 Trading Days of the first date or time that such excluded Registrable Shares may then be included in a Resale Registration Statement if the Commission
shall have notified the Company that certain Registrable Shares were not eligible for inclusion in the Resale Registration Statement or (ii) in all other cases, within 20 days following the date that the Company becomes aware that such
additional Resale Registration Statement is required (the “Additional Filing Date”), a Resale Registration Statement (any such Resale Registration Statement registering such excluded Registrable Shares, an
“Additional Registration Statement” and, together with the Mandatory Registration Statement, a “Resale Registration Statement”) to register any Registrable Shares that have been excluded (or, if
applicable, the maximum number of such excluded Registrable Shares that the Company is permitted to register for resale on such Additional Registration Statement consistent with Commission guidance), if any, from being registered on the Mandatory
Registration Statement; 
 (d)    use its commercially reasonable efforts to cause any such Additional
Registration Statement to be declared effective as promptly as practicable following the Additional Filing Date, such efforts to include, without limiting the generality of the foregoing, preparing and filing with the Commission any financial
statements or other information that is required to be filed prior to the effectiveness of any such Additional Registration Statement; 

(e)    prepare and file with the Commission such amendments and supplements to such Resale Registration Statements
and the prospectus used in connection therewith as may be 

  
 11 

 
necessary to keep such Resale Registration Statements continuously effective and free from any material misstatement or omission to state a material fact therein until termination of such
obligation as provided in Section 4.6 below, subject to the Company’s right to suspend pursuant to Section 4.5; 

(f)    furnish to the Purchaser such number of copies of prospectuses in conformity with the requirements of the
Securities Act and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Shares by the Purchaser; 

(g)    file such documents as may be required of the Company for normal securities law clearance for the resale of
the Registrable Shares in such states of the United States as may be reasonably requested by the Purchaser and use its commercially reasonable efforts to maintain such blue sky qualifications during the period the Company is required to maintain
effectiveness of the Resale Registration Statements; provided, however, that the Company shall not be required in connection with this Section 4.2(g) to qualify as a foreign corporation or execute a general consent
to service of process in any jurisdiction in which it is not now so qualified or has not so consented; 

(h)    upon notification by the Commission that the Resale Registration Statement will not be reviewed or is not
subject to further review by the Commission, the Company shall within three Trading Days following the date of such notification request acceleration of such Resale Registration Statement (with the requested effectiveness date to be not more than
two Trading Days later); 
 (i)    upon notification by the Commission that that the Resale Registration
Statement has been declared effective by the Commission, the Company shall file the final prospectus under Rule 424 of the Securities Act (“Rule 424”) within the applicable time period prescribed by Rule 424; 

(j)    advise the Purchaser promptly: 

(i)    of the effectiveness of the Resale Registration Statement or any post-effective amendments thereto; 

(ii)    of any request by the Commission for amendments to the Resale Registration Statement or amendments to the
prospectus or for additional information relating thereto; 
 (iii)    of the issuance by the Commission of any
stop order suspending the effectiveness of the Resale Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable Shares for offering or sale in any jurisdiction, or
the initiation of any proceeding for any of the preceding purposes; and 
 (iv)    of the existence of any fact
and the happening of any event that makes any statement of a material fact made in the Resale Registration Statement, the prospectus and amendment or supplement thereto, or any document incorporated by reference therein, untrue, or that requires the
making of any additions to or changes in the Resale Registration Statement or the prospectus in order to make the statements therein not misleading; 

  
 12 

 (k)    cause all Registrable Shares to be listed on each
securities exchange, if any, on which equity securities by the Company are then listed; and 
 (l)    bear all
expenses in connection with the procedures in paragraphs (a) through (l) of this Section 4.2 and the registration of the Registrable Shares on such Resale Registration Statement and the satisfaction of the blue sky
laws of such states. 
 4.3    Rule 415; Cutback. 

If at any time the staff of the Commission (“Staff”) takes the position that the offering of some or all of the
Registrable Shares in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires the Purchaser to be named as an “underwriter,” the Company
shall (in consultation with legal counsel to the lead Purchaser) use its commercially reasonable efforts to persuade the Commission that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering
“by or on behalf of the issuer” as defined in Rule 415 and that none of the Purchaser is an “underwriter.” In the event that, despite the Company’s commercially reasonable efforts and compliance with the terms of this
Section 4.3, the Staff refuses to alter its position, the Company shall (i) remove from the Registration Statement such portion of the Registrable Shares (the “Cut Back Shares”) and/or
(ii) agree to such restrictions and limitations on the registration and resale of the Registrable Shares as the Staff may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC
Restrictions”); provided, however, that the Company shall not agree to name the Purchaser as an “underwriter” in such Registration Statement without the prior written consent of the Purchaser. No liquidated damages shall
accrue as to any Cut Back Shares until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date” of such Cut
Back Shares). From and after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this Section 4 shall again be applicable to such Cut Back Shares; provided, however, that
(x) the Filing Deadline for the Registration Statement including such Cut Back Shares shall be 10 Trading Days after such Restriction Termination Date, and (y) the Effectiveness Deadline with respect to such Cut Back Shares shall be the 90th day immediately after the Restriction Termination Date or the 120th day if the Staff reviews such Registration Statement (but in any event no
later than three Trading Days from the Staff indicating it has no further comments on such Registration Statement). 

4.4    Indemnification. 

(a)    The Company agrees to indemnify and hold harmless the Purchaser and its affiliates, partners, members,
officers, directors, agents and representatives, and each Person, if any, who controls the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 the Exchange Act (each, a “Purchaser Party”
and collectively the “Purchaser Parties”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages or liabilities (collectively, “Losses”) to which they may
become subject (under the Securities Act or otherwise) insofar as such Losses (or actions or proceedings in respect thereof) arise out of, or are based upon, any material breach of this Agreement by the Company or any untrue statement or

  
 13 

 
alleged untrue statement of a material fact contained in the Resale Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or arise out of any failure by the Company to fulfill any undertaking included in the Resale Registration Statement and the Company
will, as incurred, reimburse the Purchaser Parties for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be
liable in any such case to the extent that such Loss arises out of, or is based upon: (i) an untrue statement or omission or alleged untrue statement or omission made in such Resale Registration Statement in reliance upon and in conformity with
written information furnished to the Company by or on behalf of the Purchaser specifically for use in preparation of the Resale Registration Statement; or (ii) any breach of this Agreement by the Purchaser; provided further, however,
that the Company shall not be liable to any Purchaser Party (or any partner, member, officer, director or controlling Person of the Purchaser) to the extent that any such Loss is caused by an untrue statement or omission or alleged untrue statement
or omission made in any preliminary prospectus if either (i) (A) the Purchaser failed to send or deliver a copy of the final prospectus with or prior to, or the Purchaser failed to confirm that a final prospectus was deemed to be delivered
prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the sale by the Purchaser to the Person asserting the claim from which such Loss resulted and (B) the final prospectus corrected such untrue
statement or omission, (ii) (X) such untrue statement or omission is corrected in an amendment or supplement to the prospectus and (Y) having previously been furnished by or on behalf of the Company with copies of the prospectus as so
amended or supplemented or notified by the Company that such amended or supplemented prospectus has been filed with the Commission, in accordance with Rule 172 of the Securities Act, the Purchaser thereafter fails to deliver such prospectus as so
amended or supplemented, with or prior to or the Purchaser fails to confirm that the prospectus as so amended or supplemented was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written
confirmation of the sale by the Purchaser to the Person asserting the claim from which such Loss resulted or (iii) the Purchaser sold Registrable Shares in violation of the Purchaser’s covenants contained in
Section 3.2 of this Agreement. 
 (b)    The Purchaser agrees to indemnify and hold
harmless the Company and its officers, directors, affiliates, agents and representatives and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each a
“Company Party” and collectively the “Company Parties”), from and against any Losses to which the Company Parties may become subject (under the Securities Act or otherwise),
insofar as such Losses (or actions or proceedings in respect thereof) arise out of, or are based upon, any material breach of this Agreement by the Purchaser or untrue statement or alleged untrue statement of a material fact contained in the Resale
Registration Statement (or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading in each
case, on the effective date thereof), if, and only to the extent, such untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of the
Purchaser specifically for use in preparation of the Resale Registration Statement, and the Purchaser will reimburse each Company Party for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim; provided, however, that in no event shall any 

  
 14 

 
indemnity under this Section 4.4(b) be greater in amount than the dollar amount of the net proceeds received by the Purchaser upon its sale of the Registrable Shares
included in the Registration Statement giving rise to such indemnification obligation. 
 (c)    Promptly after
receipt by any indemnified Person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying Person pursuant to this Section 4.4, such indemnified Person
shall notify the indemnifying Person in writing of such claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified Person and such indemnifying
Person shall have been notified thereof, such indemnifying Person shall be entitled to participate therein, and, to the extent that it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified Person. After
notice from the indemnifying Person to such indemnified Person of its election to assume the defense thereof, such indemnifying Person shall not be liable to such indemnified Person for any legal expenses subsequently incurred by such indemnified
Person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate in the reasonable judgment of the indemnified Person for the same counsel to
represent both the indemnified Person and such indemnifying Person or any affiliate or associate thereof, the indemnified Person shall be entitled to retain its own counsel at the expense of such indemnifying Person; provided further, that no
indemnifying Person shall be responsible for the fees and expense of more than one separate counsel for all indemnified parties. The indemnifying party shall not settle an action without the consent of the indemnified party, which consent shall not
be unreasonably withheld. 
 (d)    If after proper notice of a claim or the commencement of any action against
the indemnified party, the indemnifying party does not choose to participate, then the indemnified party shall assume the defense thereof and upon written notice by the indemnified party requesting advance payment of a stated amount for its
reasonable defense costs and expenses, the indemnifying party shall advance payment for such reasonable defense costs and expenses (the “Advance Indemnification Payment”) to the indemnified party. In the event that the
indemnified party’s actual defense costs and expenses exceed the amount of the Advance Indemnification Payment, then upon written request by the indemnified party, the indemnifying party shall reimburse the indemnified party for such
difference; in the event that the Advance Indemnification Payment exceeds the indemnified party’s actual costs and expenses, the indemnified party shall promptly remit payment of such difference to the indemnifying party. 

(e)    If the indemnification provided for in this Section 4.4 is held by a court of
competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent
permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other, as well as any other relevant equitable considerations; provided, that in no event shall any contribution by an indemnifying party hereunder be greater in amount than the dollar amount of
the proceeds received by such indemnifying party upon the sale of such Registrable Shares. 

  
 15 

 4.5    Prospectus Suspension. The Purchaser acknowledges
that there may be times when the Company must suspend the use of the prospectus forming a part of the Resale Registration Statement until such time as an amendment to the Resale Registration Statement has been filed by the Company and declared
effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act. The Purchaser hereby covenants that it will not sell any Registrable Shares pursuant to said prospectus
during the period commencing at the time at which the Company gives the Purchaser notice of the suspension of the use of said prospectus and ending at the time the Company gives the Purchaser notice that the Purchaser may thereafter effect sales
pursuant to said prospectus; provided, that such suspension periods shall in no event exceed 30 days in any 12-month period and that, in the good faith judgment of the Company’s board of directors, the
Company would, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development, a potentially significant transaction or event involving the Company, or any negotiations,
discussions, or proposals directly relating thereto, in either case the disclosure of which would reasonably be expected to have a material adverse effect upon the Company or its stockholders. 

4.6    Termination of Obligations. The obligations of the Company pursuant to
Section 4.2 hereof shall cease and terminate, with respect to any Registrable Shares, upon the earlier to occur of (a) such time such Registrable Shares have been resold, or (b) such time as such Registrable
Shares no longer remain Registrable Shares pursuant to Section 4.1(b) hereof. 

4.7    Reporting Requirements. 

(a)    With a view to making available the benefits of certain rules and regulations of the Commission that may at
any time permit the sale of the Shares to the public without registration or pursuant to a registration statement on Form S-3, the Company agrees to: 

(i)    make and keep public information available, as those terms are understood and defined in Rule 144; 

(ii)    file with the Commission in a timely manner all reports and other documents required of the Company under
the Securities Act and the Exchange Act; and 
 (iii)    so long as the Purchaser owns Registrable Shares,
furnish to the Purchaser upon request (A) a written statement by the Company as to whether it is in compliance with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, or whether it is qualified as a registrant
whose securities may be resold pursuant to Commission Form S-3, (B) 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
(C) such other information as may be reasonably requested to permit the Purchaser to sell such securities pursuant to Rule 144. 

4.8    Blue Sky. The Company shall obtain and maintain all necessary blue sky law permits and
qualifications, or secured exemptions therefrom, required by any state for the offer and sale of Registrable Shares. 

4.9    Market Stand-Off. For a period of one year following the
Closing Date, in the event that the Company conducts one or more registered public offerings of its securities in which 

  
 16 

 
Purchaser acquires securities offered thereby, the Purchaser hereby agrees to execute a customary lock-up agreement with such underwriters for a lock-up period not to exceed ninety (90) days following the pricing of any such offering.

terms and conditions of the transactions contemplated by the Transaction Documents (collectively, “Non-Public Information”), the Company covenants and agrees that neither it nor any

may reasonably request in connection with the preparation of any necessary filings or submissions by it to any Governmental Entity. 

  
 17 

 (c)    Each party hereto shall consult and cooperate with one
another, and consider in good faith the views of one another, in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party in connection with any
inquiry by any Governmental Entity relating to the transactions contemplated under this Agreement. Without limiting the generality of anything contained in this Section 5.4, each Party hereto shall give the other Parties prompt notice of

to the status of any such request, inquiry, investigation, action or legal proceeding, (ii) promptly inform the other parties of any communication to or from the FTC, DOJ or any other Governmental Entity in connection with any such request,

(d)    The Parties shall defend through litigation on the merits any claim asserted in court by any person,
including any Governmental Entity, under Antitrust Laws in order to avoid entry of, or to have vacated or terminated, any decree, order or judgment (whether temporary, preliminary or permanent) that could restrain or prevent the Closing. 

(e)    The Purchaser shall be responsible for the payment of the filing fees associated with any such applications
or filings under the HSR Act.

6.1    Termination. This Agreement may be terminated by the Purchaser, as to the Purchaser’s
obligations hereunder only, by written notice to the other parties, if the Closing has not been consummated within 60 calendar days from the Effective Date through no fault of the Purchaser; provided, however, that no such termination will
affect the right of any party to sue for any breach by the other party (or parties). 
 6.2    Fees and
Expenses. Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party

connection with the delivery of any Shares to the Purchaser. 
 6.3    Entire Agreement. The Transaction
Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such
subject matter, which the parties acknowledge have been merged into such documents, exhibits and schedules. 

6.4    Notices. Any and all notices or other communications or deliveries required or permitted to be
provided hereunder shall be in writing and shall be deemed given and effective upon actual receipt via mail, courier or confirmed email by the party to whom such notice is required to be given. The address for such notices and communications shall
be as set forth on the signature pages attached hereto. 
 6.5    Amendments; Waivers. No provision of
this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by (a) the Company and (b) the Purchaser or, in the case of a waiver, by the party against whom enforcement of any such waived
provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision,
condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. 

6.6    Headings. The headings herein are for convenience only, do not constitute a part of this Agreement
and shall not be deemed to limit or affect any of the provisions hereof. 
 6.7    Successors and Assigns.
This Agreement shall be binding upon and inure to the benefit of the parties and their permitted successors and assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the
Purchaser (other than by merger). The Purchaser may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Company (other than by merger). 

6.8    Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their
respective permitted successors and assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person. 

6.9    Governing Law. All questions concerning the construction, validity, enforcement and interpretation of
the Transaction Documents 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 and any other Transaction Documents (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 State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the State of New
York for the adjudication of any dispute hereunder or in connection herewith or with any transaction 

  
 19 

 
contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), 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. If either party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, 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. 

6.10    Execution. This Agreement may be executed in two or more counterparts, all of which when taken
together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same counterpart. In the
event that any signature on this Agreement is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a legally 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. 

6.11    Severability. If any term, provision, covenant or restriction of this Agreement is held by a court
of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or
invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction.
It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or
unenforceable. 
 6.12    Rescission and Withdrawal Right. Notwithstanding anything to the contrary
contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever the Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its
related obligations within the periods therein provided, then the Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without
prejudice to its future actions and rights. 
 6.13    Replacement of Securities. If any certificate or
instrument evidencing any Shares is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution
therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable 

  
 20 

 
indemnity or bond, if requested. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity)
associated with the issuance of such replacement Shares. 
 6.14    Remedies. The Company shall be
entitled to exercise all rights provided herein or granted by law, including recovery of damages, for any breach of the Transaction Documents. 

6.15    Construction. The parties agree that each of them and/or their respective counsel has reviewed and
had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction
Documents or any amendments hereto. 
 6.16    WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN
ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY
