with this Subscription Agreement, the “Subscription Agreements”) with certain other institutional accredited investors (the “Other Subscribers” and together with Subscriber, the “Subscribers”),
which are on substantially the same terms as the terms of this Subscription Agreement (other than the amount of the Notes to be subscribed for and purchased by the Other Subscribers), pursuant to which such investors shall agree to purchase on the
Closing Date, inclusive of the Subscribed Notes, up to $200,000,000 in aggregate principal amount of the Notes (the “Other Subscribed Notes” and together with the Subscribed Notes, the “Aggregate Subscribed Notes”);
and 
 WHEREAS, in connection with the issuance of the Notes on the Closing Date, the Company and Wilmington Trust, National Association, as

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 
 1. Subscription.
Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the

entity surviving the combination of the Company and BigBear contemplated in the Merger Agreement for working capital and other corporate purposes. 












 2. Closing. 

a. The consummation of the Subscription contemplated hereby (the “Closing”) shall be contingent upon, and
occur on the Closing Date immediately prior to or concurrently with the consummation of the Transaction. 
 b. At least five
(5) Business Days before the anticipated Closing Date, the Company shall deliver written notice to Subscriber (the “Closing Notice”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for
delivery of the Purchase Price to the Company. No later than two (2) Business Days after receiving the Closing Notice, Subscriber shall deliver to the Company such information as is reasonably requested in the Closing Notice in order for the
Company to issue the Subscribed Notes to Subscriber. Subscriber shall deliver to the Company, prior to 9:30 a.m. (Eastern time)(or as soon as practicable after the Company or its transfer agent delivers evidence of the issuance to Subscriber of the

Price) by the Company to Subscriber of the Subscribed Notes in book entry form pursuant to the DWAC procedures of the Depository Trust Company (“DTC”), which will act as securities depository for the Notes, free and clear of any
liens, encumbrances or other restrictions (other than those arising under the Indenture, this Subscription Agreement or state or federal securities laws), in the name of Subscriber or a custodian designated by Subscriber (which custodian shall have
properly posted such DWAC for release by the Trustee through the facilities of DTC), as applicable. In the event that the consummation of the Transaction does not occur within one (1) Business Day after the anticipated Closing Date specified in

immediately available funds to the account specified by Subscriber and any Subscribed Notes shall be transferred by DWAC to the Trustee and deemed cancelled and no amounts will be owned under such Subscribed Notes; provided that, unless this
Subscription Agreement has been validly terminated pursuant to Section 6 hereof, neither the failure of the Closing to occur on the Closing Date specified in the Closing Notice nor such return of funds shall
(x) terminate this Subscription Agreement, (y) be deemed to be a failure of any of the conditions to Closing set forth in Section 2(c) hereof, or (z) otherwise relieve any party of any of its obligations
hereunder, including Subscriber’s obligation to redeliver the Purchase Price and purchase the Subscribed Notes at the Closing in the event the Company delivers a subsequent Closing Notice. For the purposes of this Subscription Agreement,

party entitled to the benefit thereof under the Merger Agreement, and the closing of the Transaction shall be scheduled to occur concurrently with or immediately following the Closing; and 

(iii) no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or
regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the transactions contemplated hereby illegal or otherwise restraining, prohibiting or enjoining consummation of the
transactions contemplated hereby, and no such governmental authority shall have instituted a proceeding seeking to impose any such restraint or prohibition. 

d. The obligation of the Company to consummate the Closing shall be subject to the satisfaction or valid waiver in writing by
the Company of the additional conditions that, on the Closing Date:

(v) there has not occurred any Company Material Adverse Effect (as defined in the Merger Agreement) or Company Material

 3. Company Representations and Warranties. For purposes of this
Section 3, the term “Company” shall refer to (i) the Company as of the date hereof, and (ii) for purposes of the representations contained in subsections (f), (i), (k) and (m) of this
Section 3 and to the extent such representations and warranties are made as of the Closing Date, the combined company after giving effect to the Transaction as of the Closing Date. The Company represents and warrants
to Subscriber that as of the date hereof: 
 a. The Company (i) is duly organized, validly existing and in good standing
under the laws of the State of Delaware, (ii) has the requisite corporate power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter into and perform its obligations under
this Subscription Agreement, and (iii) is duly licensed or qualified to conduct its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the conduct of its
business or the ownership of its properties or assets requires such license or qualification, except, with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a Company Material
Adverse Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means any event, circumstance, change, development, effect or occurrence (collectively “Effect”) that, individually or
in the aggregate with all other Effects, (a) is or would reasonably be expected to be materially adverse to the business, financial condition or results of operations of the Company and its subsidiaries, taken as a whole; or (b) would
prevent, materially delay or materially impede the performance by the Company or its subsidiaries of their respective obligations under this Subscription Agreement, the Merger

Agreement or the consummation of the Transaction; provided, however, that, in the case of clause (a), none of the following shall be deemed to constitute, alone or in combination,
or be taken into account in the determination of whether, there has been or will be a Company Material Adverse Effect: (i) any change or proposed change in or change in applicable law or GAAP (including, in each case, the interpretation
thereof) after the date of this Subscription Agreement; (ii) events or conditions generally affecting the industries or geographic areas in which the Company operates; (iii) any downturn in general economic conditions, including changes in
the credit, debt, securities, financial or capital markets (including changes in interest or exchange rates, prices of any security or market index or commodity or any disruption of such markets); (iv) acts of war, sabotage, civil unrest or
terrorism, or any escalation or worsening of any such acts of war, sabotage, civil unrest or terrorism, or changes in global, national, regional, state or local political or social conditions; (v) any hurricane, tornado, flood, earthquake,

executed and delivered in connection with the Transaction and specifically contemplated by the Merger Agreement or (vii) any Effect attributable to the announcement or execution, pendency, negotiation or consummation of the Transaction, except
in the cases of clauses (i) through (iii), to the extent that the Company is materially and disproportionately affected thereby as compared with other participants in the industry in which the Company operates. 

b. As of the Closing Date, the Subscribed Notes will be duly authorized and, when issued and delivered to Subscriber against
full payment therefor in accordance with the terms of this Subscription Agreement, will be validly issued and will constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except
that the enforcement thereof may be subject to applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally or by equitable principles relating to enforceability (collectively, the “Enforceability
Exceptions”), and will not have been issued in violation of any preemptive rights created under the Company’s organizational documents or the laws of the State of Delaware. The Indenture has been duly authorized by the Company and,
when duly authorized, executed and delivered by the Trustee, will constitute a legal, valid and binding obligation of the Company, enforceable against the Company, respectively, in accordance with its terms, except that the enforcement thereof may
be subject to the Enforceability Exceptions. 
 c. The Subscribed Notes are not, and following the Closing, will not be,
subject to any Transfer Restriction. The term “Transfer Restriction” means any condition to or restriction on the ability of Subscriber or any other holder of the Subscribed Notes to pledge, sell, assign or otherwise transfer the

respect to the status of the Subscribed Notes as “restricted securities” pending their registration for resale under the Securities Act of 1933, as amended (the “Securities Act”), in accordance with the terms of this
Subscription Agreement. 
 d. This Subscription Agreement has been duly authorized, executed and delivered by the Company,
and assuming the due authorization, execution and delivery of the same by Subscriber, this Subscription Agreement shall constitute the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms,
subject to the Enforceability Exceptions.

 e. The execution and delivery of this Subscription Agreement, the issuance
and sale of the Subscribed Notes, the issuance and delivery of shares of Common Stock upon conversion of the Subscribed Notes in accordance with the terms of the Indenture and the compliance by the Company with all of the provisions of this
Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or
imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the
Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; or (iii) any statute or any judgment, order, rule or regulation of
any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect or
have a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Notes. 

f. Assuming the accuracy of the representations and warranties of Subscriber, the Company is not required to obtain any
consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including Nasdaq in connection with the

obtaining approval of the Company’s stockholders, (iv) filings required to consummate the Transaction as provided under the Merger Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, if applicable, (vi) those that will be obtained, made or given, as applicable, on or prior to the Closing, and (vii) consents, waivers, authorizations, orders, notices or filings, the failure of which to obtain, make or give would
not be reasonably likely to have a Company Material Adverse Effect or have a material adverse effect on the Company’s legal authority to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Notes.

 g. As of their respective dates, all reports required to be filed by the Company with the Commission (the “SEC
Reports”) complied in all material respects with the applicable requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission
promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the
Commission with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then
ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments.

consummation of the Transaction), the entire authorized capital stock of the Company will consist of 500,000,000 shares of Common Stock and 1,000,000 Preferred Shares. As of the date hereof, and (assuming no redemptions) immediately prior to the

marketing agreement entered into in connection with its initial public offering) and will not have any long-term indebtedness immediately prior to the Closing. No Warrants are exercisable on or prior to the Closing. All (i) issued and
outstanding Common Stock has been duly authorized and validly issued, is fully paid and non-assessable and is not subject to preemptive rights and (ii) issued and outstanding Warrants constitute legal,
valid and binding obligations of the Company, enforceable against the Company in accordance with their terms. As of the date hereof, except as set forth above and pursuant to the Other Subscription Agreements and the Merger Agreement, there are no
outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Company any Common Stock or other equity interests in the Company (collectively, “Equity Interests”) or securities convertible into or
exchangeable or exercisable for Equity Interests. As of the date hereof, the Company has no subsidiaries (other than Merger Sub) and does not own, directly or indirectly, interests or investments (whether equity or debt) in any person, whether

Equity Interests, other than (A) the letter agreements entered into by the Company in connection with the Company’s initial public offering on February 11, 2021 pursuant to which the Company’s sponsor and the Company’s
executive officers and independent directors agreed to vote in favor of any proposed Business Combination (as defined therein), which includes the Transaction, and (B) as contemplated by the Merger Agreement. There are no securities or
instruments issued by or to which the Company is a party containing anti-dilution or similar provisions that will be triggered by the issuance of (i) the Subscribed Notes, (ii) any Notes to be issued pursuant to any Other Subscription
Agreement or (iii) any shares of Common Stock upon conversion of any of the Subscribed Notes or any of the Notes to be issued pursuant to any Other Subscription Agreement. 

i. Except for such matters as have not had and would not be reasonably likely to have a Company Material Adverse Effect or have
a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Notes, as of the date hereof, there is no (i) suit, action, proceeding or arbitration
before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding
against the Company.

 j. The issued and outstanding shares of Common Stock are registered pursuant
to Section 12(b) of the Exchange Act and are listed for trading on Nasdaq under the symbol “GIG” (it being understood that the trading symbol will be changed in connection with the Transaction). There is no suit, action, proceeding or
investigation pending or, to the knowledge of the Company, threatened against the Company by Nasdaq or the Commission with respect to any intention by such entity to deregister the shares of Common Stock or prohibit or terminate the listing of the
shares of Common Stock on Nasdaq. The Company has taken no action that is designed to terminate the registration of the shares of Common Stock under the Exchange Act. Prior to the Closing, the Company will file a listing application with Nasdaq for
the shares of Common Stock underlying the Notes and such application will be approved by Nasdaq subject to notice of issuance. 

k. Assuming the accuracy of all of Subscriber’s representations and warranties set forth in
Section 4 of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Subscribed Notes by the Company to Subscriber and the Subscribed Notes are not being offered in a
manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities law.

commission from the Company solely in connection with the sale of the Subscribed Notes to Subscriber. 
 n. Except for such
matters as have not had a Company Material Adverse Effect, the Company is in compliance with all state and federal laws applicable to the conduct of its business. The Company has not received any written, or to its knowledge, other communication
from a governmental entity that alleges that the Company is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not be
reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect. Except for such matters as have not had and would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect
as of the date hereof, there is no (i) action, lawsuit, claim or other proceeding, in each case by or before any governmental authority pending, or, to the knowledge of the Company, threatened against the Company or (ii) judgment, decree,
injunction, ruling or order of any governmental entity or arbitrator outstanding against the Company. 
 o. The Company has
not in the past nor will it hereafter take any action to sell, offer for sale or solicit offers to buy any securities of the Company that could result in the initial sale of the Subscribed Notes not being exempt from the registration requirements of
Section 5 of the Securities Act. 
 p. The Subscribed Notes, when issued, will not be of the same class as a securities

 q. The Company acknowledges and agrees that, notwithstanding anything herein
to the contrary, the Subscribed Notes may be pledged by the Subscriber in connection with a bona fide margin agreement, which shall not be deemed to be a transfer, sale or assignment of the Subscribed Notes hereunder, and the Subscriber effecting a
pledge of Subscribed Notes shall not be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Subscription Agreement; provided that such pledge shall be pursuant to an available
exemption from the registration requirements of the Securities Act.

of payment for the Subscribed Notes will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

s. The Company is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would
constitute a default or violation) of any term, condition or provision of (i) the Company’s organizational documents, (ii) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or
license to which the Company is now a party or by which the Company’s properties or assets are bound or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having
jurisdiction over the Company or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations that have not had and would not be reasonably likely to have, individually or in the aggregate, a Company Material
Adverse Effect. 
 4. Subscriber Representations and Warranties. Subscriber represents and warrants to the Company that as of

jurisdiction of incorporation, and (ii) has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement. 

b. This Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization,
execution and delivery of the same by the Company, this Subscription Agreement shall constitute the valid and legally binding obligation of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be
limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws affecting creditors generally and by the availability of equitable remedies. 

c. The execution and delivery of this Subscription Agreement, the purchase of the Subscribed Notes and the compliance by
Subscriber with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default
under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other
agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any statute or any
judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected

to have a Subscriber Material Adverse Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence,
condition or effect with respect to Subscriber that would reasonably be expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of the Subscribed Notes. 

d. Subscriber (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an
institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act), in either case, satisfying the applicable requirements set forth on Annex A hereto, and an “institutional
account” as defined in FINRA Rule 4512(c), (ii) is acquiring the Subscribed Notes only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed Notes as a fiduciary or agent for one or more
investor accounts, each owner of such account is a qualified institutional buyer or an institutional accredited investor and Subscriber has full investment discretion with respect to each such account, and the full power and authority to make the
acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Subscribed Notes with a view to, or for offer or sale in connection with, any distribution thereof in violation
of the Securities Act (and has provided the Company with the requested information on Annex A). Subscriber is not an entity formed for the specific purpose of acquiring the Subscribed Notes. 

e. Subscriber understands that the Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes are
being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes have not been registered under the
Securities Act. Subscriber understands that the Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes may not be offered, resold, transferred, pledged (other than in connection with ordinary course prime brokerage
relationships) or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary thereof, (ii) to non-U.S. persons
pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and, in
each of cases (ii) and (iii), in accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any book-entry positions or certificates representing the Subscribed Notes shall contain the

applicable securities laws and, as a result of these transfer restrictions, Subscriber may not be able to readily offer, resell, transfer, pledge (other than in connection with ordinary course prime brokerage relationships) or otherwise dispose of
the Subscribed Notes and may be required to bear the financial risk of an investment in the Subscribed Notes for an indefinite period of time. Subscriber understands that it has been advised to consult legal counsel and tax and accounting advisors
prior to making any offer, resale, pledge, transfer or disposition of any of the Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes. 

Each book entry for the Subscribed Notes shall contain a notation, and each certificate (if any) evidencing the Notes shall be
stamped or otherwise imprinted with a legend, in substantially the following form:

 f. Subscriber understands and agrees that Subscriber is purchasing the
Subscribed Notes directly from the Company. Subscriber further acknowledges that there have not been, and Subscriber hereby expressly and irrevocably acknowledges and agrees that it is not relying on, any representations, warranties, covenants,
agreements or statements made to Subscriber by or on behalf of the Company, BigBear or the Company or BigBear’s respective affiliates or any of the respective subsidiaries, control persons, officers, directors, employees, partners, agents or
representatives, or any other party to the Transaction or any other person or entity (including the Placement Agent), expressly or by implication (including by omission), other than those representations, warranties, covenants, agreements and
statements of the Company expressly set forth in this Subscription Agreement and in the Indenture, and Subscriber is not relying on any other purported representations, warranties, covenants, agreements or statements (including by omission) are
hereby disclaimed by Subscriber. Subscriber acknowledges that certain information provided by the Company was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject
to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. 

g. In making its decision to purchase the Subscribed Notes (including the Common Stock issuable upon conversion of the
Subscribed Notes), Subscriber has relied solely upon independent investigation made by Subscriber and upon the representations, warranties and covenants of the Company expressly set forth herein and in the Indenture (and no other representations and
warranties). Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Notes and the Common Stock issuable upon conversion of
the Subscribed Notes, including with respect to the Company, the Transaction and the business of BigBear and each of its subsidiaries (collectively, the “Acquired Companies”). Without limiting the generality of the foregoing,
Subscriber acknowledges that Subscriber has reviewed the SEC Reports. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers
and obtain such information as Subscriber and such Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Notes. Subscriber acknowledges and agrees that neither
Oppenheimer & Co. Inc. acting as placement agent to the Company (the “Placement Agent”), nor any affiliate of the Placement Agent has provided Subscriber with any information or advice with respect to the Subscribed Notes
and the Common Stock issuable upon conversion of the Subscribed Notes nor is such information or advice necessary or desired. Neither the Placement Agent nor any of its affiliates has made or makes any representation or warranty, whether express or
implied, of any kind or character as to the Company or the Acquired Companies or the quality or value of the Subscribed Notes and the Placement Agent and any of its respective affiliates may have acquired
non-public information with respect to the Company or the Acquired Companies which Subscriber agrees need not be provided to it. In connection with the issuance of the Subscribed Notes to Subscriber, neither
the Placement Agent nor any of its affiliates has acted as a financial advisor or fiduciary to Subscriber. 
 h. Subscriber
acknowledges and is aware that Oppenheimer & Co. Inc. (“Oppenheimer”) served as an underwriter in the Company’s initial public offering and entered into that certain Unit Purchase Agreement dated February 9, 2021
by and among the Company, Nomura Securities International, Inc. and Oppenheimer through which Oppenheimer purchased 199,680 private units; each unit consisting of one share of common stock of the Company and
one-third of one warrant, each whole warrant exercisable to purchase one share of Common Stock. Subscriber hereby waives any claims it may have based on any actual or potential conflict of interest or similar
claims relating to or arising from Oppenheimer acting as Placement Agent to the Company.

 i. Subscriber became aware of this offering of the Subscribed Notes solely
by means of direct contact between Subscriber and the Company or by means of contact from the Placement Agent, BigBear or its subsidiaries and/or their respective advisors (including, without limitation, attorneys, accountants, bankers, consultants
and financial advisors), agents, control persons, representatives, affiliates, directors, officers, managers, members, and/or employees, and/or the representatives of such persons (such parties referred to collectively as
“Representatives”). The Subscribed Notes were offered to Subscriber solely by direct contact between Subscriber and the Company, the Placement Agent, BigBear or its subsidiaries and/or their respective Representatives. Subscriber
did not become aware of this offering of the Subscribed Notes, nor were the Subscribed Notes offered to Subscriber, by any other means, and none of the Company, the Placement Agent, BigBear or its subsidiaries or their respective Representatives
acted as investment advisor, broker or dealer to Subscriber. Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person or entity (including, without limitation, the
Company, the Placement Agent, BigBear and/or their respective Representatives), other than the representations and warranties expressly set forth in this Subscription Agreement, in making its investment or decision to invest in the Company.
Subscriber acknowledges that the Company represents and warrants that the Subscribed Notes (i) were not offered by any form of general solicitation or general advertising, including methods described in Section 502(c) of Regulation D under
the Securities Act, and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. 

j. Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the
Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the
Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes, and Subscriber has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Subscriber has considered necessary to make an
informed investment decision. Subscriber acknowledges that it (i) is a sophisticated investor, experienced in investing in business and financial transactions and capable of evaluating investment risks independently, both in general and with
regard to all transactions and investment strategies involving a security or securities, and (ii) has exercised independent judgment in evaluating its purchase of the Subscribed Notes (including the Common Stock issuable upon conversion of the
Subscribed Notes). Subscriber understands that the purchase and sale of the Subscribed Notes hereunder meets (i) the exemptions from filing under FINRA Rule 5123(b)(1)(A) and (ii) the institutional customer exemption under FINRA Rule
2111(b). 
 k. Alone, or together with any professional advisor(s), Subscriber represents and acknowledges that Subscriber
has adequately analyzed and fully considered the risks of an investment in the Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes and determined that the Subscribed Notes are a suitable investment for Subscriber
and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists. 

  
 13 













 l. Subscriber understands and agrees that no federal or state agency has
passed upon or endorsed the merits of the offering of the Subscribed Notes (including the Common Stock issuable upon conversion of the Subscribed Notes) or made any findings or determination as to the fairness of this investment. 

m. Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons
administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by the President of the United States and administered by OFAC, or any other list of prohibited or
restricted parties promulgated by OFAC, the Department of Commerce, or the Department of State (“Consolidated Sanctions Lists”), or a person or entity prohibited or restricted by any OFAC sanctions program, or a person or entity
whose property and interests in property subject to U.S. jurisdiction are otherwise blocked under any U.S. laws, Executive Orders or regulations, (ii) a person or entity listed on the Sectoral Sanctions Identifications (“SSI”)
List maintained by OFAC or otherwise determined by OFAC to be subject to one or more of the Directives issued under Executive Order 13662 of March 20, 2014, or on any other of the Consolidated Sanctions Lists, (iii) an entity owned,
directly or indirectly, individually or in the aggregate, 50 percent or more by, acting on behalf of, or controlled by, one or more persons described in subsections (i) or (ii), (iv) organized, incorporated, established, located,
resident or born in, or a citizen, national or the government, including any political subdivision, agency or instrumentality thereof, of, Cuba, Iran, North Korea, Myanmar, Venezuela, Syria, the Crimea region of Ukraine or any other country or

banking services indirectly to a non-U.S. shell bank (collectively, (i) through (vii), a “Restricted Person”). Subscriber agrees to provide law enforcement agencies, if requested thereby,
such records as required by applicable law, provided that Subscriber is permitted to do so under applicable law. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as
amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the
BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it maintains policies and procedures reasonably designed for the screening of its investors against the OFAC and BIS sanctions programs, including for Restricted Persons, and
otherwise to ensure compliance with all applicable sanctions and embargo laws, statutes, and regulations. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure
that the funds held by Subscriber and used to purchase the Subscribed Notes were legally derived and were not obtained, directly or indirectly, from a Restricted Person. Subscriber is not a “foreign person,” “foreign government,”
or a “foreign entity,” in each case, as defined in Section 721 of the Defense Production Act of 1950, as amended, including, without limitation, all implementing regulations thereof (the “DPA”). Subscriber is not
controlled, in whole or in part, by a “foreign person,” as defined in the DPA. 

  
 14 













 n. Subscriber does not have, as of the date hereof, and during the 30-day period immediately prior to the date hereof Subscriber has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the
Exchange Act or short sale positions with respect to the securities of the Company. Notwithstanding the foregoing, in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of
Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of Subscriber’s assets, the representation set forth above shall only apply with
respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Notes covered by this Subscription Agreement. 

o. If Subscriber is an employee benefit plan that is subject to Title I of ERISA, a plan, an individual retirement account or
other arrangement that is subject to Section 4975 of the Code or an employee benefit plan that is a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA), a non-U.S. plan (as described in Section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing but may be subject to provisions under any other federal, state, local,
non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Internal Revenue Code of 1986, as amended, or an entity whose underlying assets are considered to include “plan
assets” of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions of ERISA or Section 4975 of the Code, then Subscriber represents and warrants that neither the
Company, nor any of its respective affiliates (the “Transaction Parties”) has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its decision to acquire and hold the Subscribed Notes, and none of
the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the Subscribed Notes. 

p. At the Closing, Subscriber will have sufficient funds to pay the Purchase Price pursuant to
Section 2(b) of this Subscription Agreement. 
 q. No disclosure or offering document has been
prepared by the Placement Agent in connection with the offer and sale of the Subscribed Notes. The Placement Agent and each of its Representatives have made no independent investigation with respect to the Company, BigBear or its subsidiaries, or
the Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes or the accuracy, completeness or adequacy of any information supplied to Subscriber by the Company. In connection with the issue and purchase of the
Subscribed Notes and the Common Stock issuable upon conversion of the Subscribed Notes, the Placement Agent has not acted as Subscriber’s financial advisor or fiduciary. 

r. Subscriber agrees that, notwithstanding Section 8(j) of this Subscription Agreement, the Placement
Agent and BigBear may rely upon the representations and warranties made by Subscriber to the Company in this Subscription Agreement. 

s. No foreign person (as defined in 31 C.F.R. Part 800.224) in which the national or subnational governments of a single
foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in the Company as a result of the purchase and sale of securities hereunder such that a declaration to the Committee on Foreign
Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over the Company from and after the Closing as a result of the purchase and sale of the
Subscribed Notes hereunder. 

  
 15 













 t. No broker, finder or other financial consultant has acted on behalf of
Subscriber in connection with this Subscription Agreement or the transactions contemplated hereby in such a way as to create any liability on the Company. 

u. Except for the representations and warranties contained in this Section 4, Subscriber makes no
express or implied representation or warranty, and Subscriber hereby disclaims any such representation or warrant with respect to the execution and delivery of this Agreement and the consummation of the transactions contemplated herein. 

5. Registration of Subscribed Notes. 

a. The Company agrees that on or prior to the earlier of (i) forty-five (45) calendar days after the Closing and
(ii) the date that the Company files any other registration statement registering the resale of any securities in connection with the Transaction (such earlier date, the “Filing Deadline”), the Company will file with the
Commission (at the Company’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Subscribed Notes and the shares of Common Stock issuable upon conversion of the
Subscribed Notes (including, for the avoidance of doubt, any shares of Common Stock issuable in connection with the Interest Make-Whole Amount (as defined in the Indenture)) (the “Registrable Securities”), and the Company shall use
its commercially reasonable efforts to have the Registration Statement declared effective as soon as reasonably practicable after the filing thereof, but no later than the earlier of (i) the 60th
calendar day (or 120th calendar day if the Commission notifies the Company that it will “review” the Registration Statement) following the Closing and (ii) ten (10) Business Days after the Company is notified (orally or in
writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or be subject to further review (such date, the “Effectiveness Date”). The Company’s obligations to include the
Registrable Securities in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition
of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and shall execute such documents in connection with such registration as the Company may reasonably request that
are customary of a selling stockholder in similar situations; provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject
to any contractual restriction on the ability to transfer the Registrable Securities. Notwithstanding the foregoing, if the Effectiveness Date falls on a day which is not a Business Day or other day that the Commission is closed for business, the
Effectiveness Date shall be extended to the next Business Day on which the Commission is open for business. The Company will provide a draft of the Registration Statement to Subscriber for review at least three (3) Business Days in advance of
filing the Registration Statement. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided, that, if the Commission requests that Subscriber be identified as a
statutory underwriter in the Registration Statement, Subscriber will have an opportunity to withdraw the Registrable Securities from the Registration Statement. Notwithstanding the foregoing, if the Commission prevents the Company from including any
or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities by the applicable shareholders or otherwise, such
Registration Statement shall register for resale such number of Registrable Securities which is equal to the maximum number of Registrable Securities as is permitted by the 

  
 16 













 
Commission. In such event, the number of Registrable Securities to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling
shareholders. For purposes of clarification, any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Company of its
obligations to file or effect the Registration Statement set forth in this Section 5. 
 b. In the
case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, respond to Subscriber as to the status of such registration, qualification,
exemption and compliance. At its expense the Company shall: 
 (i) except for such times as the Company is permitted
hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement, and to be supplemented and amended to the extent
necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities, until the earliest of (i) the date on which all of the
Registrable Securities may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act, (ii) the date on which all of the Registrable Securities have actually been sold pursuant to Rule 144
or pursuant to the Registration Statement, and (iii) the date which is three years after the Closing. 
 (ii) advise
Subscriber, as expeditiously as possible: 
 (1) when a Registration Statement or any amendment thereto has been filed with
the Commission; 
 (2) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any
stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; 

(3) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable
Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(4) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any
changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case
of a prospectus, in the light of the circumstances under which they were made) not misleading. 
 Notwithstanding anything to the contrary
set forth herein, the Company shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Company other than to the extent that providing notice to the Company of the occurrence of
the events listed in (1) through (4) above may constitute material, nonpublic information regarding the Company; 

  
 17 













 (iii) use its commercially reasonable efforts to obtain the withdrawal of
any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable; 
 (iv) upon the
occurrence of any event contemplated in Section 5(b)(ii)(4) above, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement,
the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that,
as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; 
 (v) cause the Registrable Securities to be listed on each
securities exchange or market, if any, on which the shares of Common Stock issued by the Company have been listed; 
 (vi)
use its commercially reasonable efforts to allow Subscriber to review disclosure regarding the Investor in the Registration Statement; 

(vii) for as long as Subscriber holds Registrable Securities, use commercially reasonable efforts to file all reports for so
long as the condition in Rule 144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Registrable Securities pursuant to Rule
144 of the Securities Act (in each case, when Rule 144 of the Securities Act becomes available to Subscriber); and 
 (viii)
otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by Subscriber, consistent with the terms of this Subscription Agreement, in connection with the registration of the Registrable
Securities. 
 c. Notwithstanding anything to the contrary in this Subscription Agreement, the Company shall be entitled to
delay or postpone the effectiveness of the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, (x) if (i) it determines that in order for
the Registration Statement not to contain a material misstatement or omission, an amendment or supplement thereto would be needed or (ii) the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event
has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material
information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the
Company’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements and (y) as may be necessary in connection with the preparation and filing of a
post-effective amendment to the Registration Statement following the filing of the Company’s (including the combined company after giving effect to the Transaction) Annual Report on Form 10-K for its
first 

  
 18 













 
completed fiscal year following the Closing (each such circumstance, a “Suspension Event”); provided, however, that (A) the Company may not delay or suspend the Registration
Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than a total of ninety (90) calendar days, in each case during any twelve-month period and (B) the Company shall use commercially
reasonable efforts to make such Registration Statement available for sale by Subscriber of such securities as soon as practicable thereafter. Upon receipt of any written notice from the Company of the happening of any Suspension Event (which notice
shall not contain material non-public information) during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus
contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus)
not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Registrable Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until
Subscriber receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become
effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required
by law or subpoena. If so directed by the Company, Subscriber will deliver to the Company or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities in Subscriber’s possession; provided,
however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Securities shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with
applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on
archival servers as a result of automatic data back-up. 
 d. The Company shall,
notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), and its officers, directors and agents, and each person who controls Subscriber
(within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without
limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration
Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or
(ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this
Section 5, except, in each case, to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in
writing to the Company by Subscriber expressly for use therein or Subscriber has omitted a material fact from such information; provided, however, that the indemnification contained in this Section 5 shall not apply to


  
 19 













 
amounts paid in settlement of any Losses if such settlement is effected by Subscriber without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or
delayed), nor shall the Company be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in connection with any failure of Subscriber to deliver or cause to be delivered a prospectus made available
to Subscriber by the Company in a timely manner, (B) as a result of offers or sales effected by or on behalf of Subscriber by means of a freewriting prospectus (as defined in Rule 405) that was not authorized by the Company, or (C) in
connection with any offers or sales effected by or on behalf of a Subscriber in violation of Section 5(c) of this Subscription Agreement. The Company shall notify Subscriber promptly of the institution, threat or assertion
of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which the Company is aware. The indemnity set forth in this Section 5(d) shall remain in full
force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Registrable Securities by Subscriber. 

e. If the total number of shares of Common Stock that Subscriber and any other person(s) intend to include in an underwritten
offering exceeds the number of shares of Common Stock that can be sold in an underwritten offering without being likely to have an adverse effect on the price, timing or distribution of shares of the Common Stock offered or the market for the shares
of Common Stock as determined by the managing underwriter of such offering, then the shares of Common Stock to be included in such offering shall include the number of shares of Common Stock that the managing underwriter of the offering advises the
Company can be sold without having such adverse effect, with such number to be allocated (i) first, to the Company or other party or parties requesting or initiating such registration or to any other holder of securities of the Company having
rights of registration pursuant to an existing registration rights agreement, (ii) second, Subscribers, allocated among Subscribers on the basis of the number of shares of Common Stock proposed to be sold by each applicable Subscriber in such
underwritten offering (based, for each such participant described in this clause (ii), on the percentage derived by dividing (x) the number of shares of Common Stock proposed to be sold by such participant in such underwritten offering by
(y) the aggregate number of shares of Common Stock proposed to be sold by all such participants) or in such manner as they may agree, and (iii) third, to other holders of shares of Common Stock with registration rights entitling them to
participate in such underwritten offering. 
 f. Subscriber shall, severally and not jointly with the Other Subscribers,
indemnify and hold harmless the Company, its directors, officers, agents, trustees, partners, members, managers, stockholders, affiliates, investment advisors and employees, and each person who controls the Company (within the meaning of
Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or based upon any untrue or alleged untrue statement of a
material fact contained in the Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any
omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they
were made) not misleading, in any such case to the extent, but only to the extent, that such untrue statements or omissions are based upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein;
provided, however, that the indemnification contained in this Section 5(f) shall not apply to amounts paid in settlement 

  
 20 













 
of any Losses if such settlement is effected without the consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed) nor shall Subscriber be liable for any
Losses to the extent they arise out of or are based upon a violation which occurs in reliance upon and in conformity with written information furnished by the Company. In no event shall the liability of Subscriber be greater in amount than the
dollar amount of the net proceeds received by Subscriber upon the sale of the Registrable Securities giving rise to such indemnification obligation. Subscriber shall notify the Company promptly of the institution, threat or assertion of any
proceeding arising from or in connection with the transactions contemplated by this Section 5(f) of which such Subscriber is aware of which Subscriber shall seek indemnification under this Subscription Agreement;
provided that the failure by Subscriber to give such notice shall not relieve the Company of its indemnification obligations hereunder, except to the extent that the failure to give such notice is materially prejudicial to the company’s
ability to defend such claim or litigation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Registrable Securities by such
Subscriber. 
 g. Any person or entity entitled to indemnification herein shall (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not
prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying
party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of
more than one counsel for all parties indemnified by such indemnifying party with respect to such claims, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment
of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement), which settlement shall not include a statement or admission of fault and culpability on the party of such indemnified party, and which
settlement shall include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 

h. If the indemnification provided under this Section 5 from the indemnifying party is unavailable or
insufficient to hold harmless an indemnified party in respect of any Losses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a
result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the
Subscriber shall be limited to the net proceeds received by Subscriber from the sale of Subscribed Notes giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by
reference to, among other things, whether any 

  
 21 













 
action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an
omission), or relates to information supplied by (or not supplied by, in the case of an omission) such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses shall be deemed to include, subject to the limitations set forth in this Section 5, any legal or
other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled
to contribution pursuant to this Section 5(h) from any person or entity who was not guilty of such fraudulent misrepresentation. 

i. The Subscriber may deliver written notice (an “Opt-Out Notice”) to
the Company requesting that the Subscriber not receive notices from the Company otherwise required by this Section 5; provided, however, that the Subscriber may later revoke any such
Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the Subscriber (unless subsequently revoked), (i) the Company shall not deliver any such notices
to the Subscriber and the Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to the Subscriber’s intended use of an effective Registration Statement, the Subscriber will notify the
Company in writing at least two business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 5(i)) and
the related suspension period remains in effect, the Company will so notify the Subscriber, within one business day of the Subscriber’s notification to the Company, by delivering to the Subscriber a copy of such previous notice of Suspension
Event, and thereafter will provide the Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability (which notices shall not contain any material, nonpublic information or subject the Subscriber to
any duty of confidentiality). 
 j. For purposes of this Section 5, (i) “Subscriber”
shall include any person to whom the rights under this Section 5 shall have been duly assigned and (ii) “Registrable Securities” shall mean, as of any date of determination, the Registrable Securities acquired by
the Subscriber pursuant to this Subscription Agreement and any other equity security issued or issuable with respect to such Registrable Securities by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or
similar event. 
 6. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all
rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Merger Agreement is terminated in accordance
with its terms, (b) upon the mutual written agreement of the Company and Subscriber to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transaction, any of the conditions to Closing set forth in
Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived (to the extent a valid waiver is capable of being issued) by the party entitled to grant such
waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated, or (d) February 3, 2022; provided, that nothing herein will relieve any party from liability for any willful breach hereof
(including, for the avoidance of doubt, a Subscriber’s willful breach of Section 2(d) of this Subscription Agreement with respect to its representations, warranties and covenants as of the date of the Closing) prior to
the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities 

  
 22 













 
or damages arising from such breach. The Company shall notify Subscriber of the termination of the Merger Agreement promptly after the termination thereof. For the avoidance of doubt, if any
termination hereof occurs after the delivery by the Subscriber of the Purchase Price for the Subscribed Notes, the Company shall promptly (but not later than one business day thereafter) return the Purchase Price to the Subscriber by wire transfer
of immediately available funds to the account specified by Subscriber without any deduction for or on account of any tax, withholding, charges, or set-off. 

7. Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust
Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit
of the Company’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (i) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account,
and shall not make any claim against the Trust Account, in each case, to the extent such claim arises as a result of, in connection with or relating in any way to this Subscription Agreement or any other matter, and regardless of whether such claim
arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (ii) irrevocably waives any Released Claims that it may have
against the Trust Account now or in the future as a result of, or arising out of this Subscription Agreement, and (iii) will not seek recourse against the Trust Account for any Released Claim; provided however, that nothing in this
Section 7 shall be deemed to limit any Subscriber’s right to distributions or redemptions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of any
redemptions by Subscriber of its shares of public Common Stock of the Company currently outstanding on the date hereof and acquired by any means other than pursuant to this Subscription Agreement. Subscriber agrees not to seek recourse or make or
bring any action, suit, claim or other proceeding against the Trust Account as a result of, or arising out of, this Subscription Agreement, the transactions contemplated hereby or the Subscribed Notes regardless of whether such claim arises based on
contract, tort, equity or any other theory of legal liability. The Subscriber acknowledges and agrees that it shall not have any redemption rights with respect to the Subscribed Notes pursuant to the Company’s organizational documents in
connection with the Transaction or any other business combination, any subsequent liquidation of the Trust Account, the Company or otherwise, except as set forth in the Indenture. In the event Subscriber has any claim against the Company as a result
of, or arising out of, this Subscription Agreement, the transactions contemplated hereby or the Subscribed Notes, it shall pursue such claim solely against the Company and its assets outside the Trust Account and not against the Trust Account or any
monies or other assets in the Trust Account. 
 8. Miscellaneous. 

a. All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand,
claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail, on the date of transmission to such recipient; provided, that such notice, request,
demand, claim or other communication is also sent to the recipient pursuant to clauses (i), (iii) or (iv) of this Section 8(a), (iii) one Business Day after being sent to the recipient by reputable overnight courier
service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and, in each case, addressed to the intended recipient at its address
specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 8(a). 

  
 23 













 b. Subscriber acknowledges that (i) the Company, BigBear and BBAI will
rely on the acknowledgments, understandings, agreements, representations and warranties made by Subscriber contained in this Subscription Agreement and (ii) the Placement Agent will rely on the representations and warranties made by Subscriber
contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Company, BigBear, BBAI and the Placement Agent if it becomes aware that any of the acknowledgments, understandings, agreements, representations
and warranties of Subscriber set forth herein are no longer accurate in all material respects. The Company acknowledges that Subscriber and others (including Placement Agent) will rely on the acknowledgments, understandings, agreements,
representations and warranties contained in this Subscription Agreement. 
 c. Each of the Company, BigBear, BBAI and
Subscriber is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party as requested or required by law, rule or regulation in any administrative or legal proceeding or official inquiry with respect to
the matters covered hereby; provided that, with respect to production by the Company, BigBear or BBAI, such party will provide Subscriber with at least three (3) Business Days’ prior written notice of such production to the extent legally
permissible and subject to Section 8(s). 
 d. Regardless of whether the Closing occurs, Subscriber
shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein. 

e. Regardless of whether the Closing occurs, the Company shall be solely responsible for and shall bear all costs and expenses
incurred by or on behalf of the Company in connection with this Subscription Agreement. 
 f. Neither this Subscription
Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Notes acquired hereunder, if any) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Company hereunder
may be transferred or assigned (provided, that, for the avoidance of doubt, the Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transaction and exclusively to another entity
under the control of, or under common control with, the Company). Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates (including other investment funds or
accounts managed or advised by the investment manager who acts on behalf of Subscriber) or, with the Company’s prior written consent, to another person, provided that no such assignment shall relieve Subscriber of any of its obligations
hereunder if any such assignee fails to perform such obligations, unless the Company has given its prior written consent to such relief, and such assignee agrees in writing to be bound by the terms hereof. The parties hereto acknowledge and agree
that (i) BBAI and BigBear are third party beneficiaries hereof and no consent, waiver, modification or amendment hereunder or hereof (including, for the avoidance of doubt, any amendment to the Indenture attached hereto as Exhibit A) may
be given or agreed to by the Company without BBAI’s and BigBear’s prior written consent, (ii) this Subscription Agreement is being entered into in order to induce each of the Company, BBAI and BigBear to execute and deliver the Merger
Agreement and without the representations, warranties, covenants and agreements of the Company and Subscriber hereunder, each of the Company, BBAI and BigBear would not enter into the Merger Agreement, (iii) each representation, warranty,
covenant and 

  
 24 













 
agreement of the Company and Subscriber hereunder is being made also for the benefit of BBAI and BigBear, and (iv) BBAI and BigBear may directly enforce (including by an action for specific
performance, injunctive relief or other equitable relief) each of the covenants and agreements of each of the Company and Subscriber under this Subscription Agreement. 

g. All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive
the Closing. 
 h. The Company may request from Subscriber such additional information as the Company may reasonably
determine necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Notes, to register the resale of the Registrable Securities or otherwise consummate or evidence the transaction contemplated by this Subscription Agreement, and
Subscriber shall provide such information as may be reasonably requested to the extent readily available and to the extent consistent with its internal policies and procedures; provided that Company agrees to keep any such information provided by
Subscriber confidential other than as necessary to include in any registration statement the Company is required to file hereunder or in connection herewith. Subscriber acknowledges and agrees that if it does not provide the Company with such
requested information, the Company may not be able to register the Subscribed Notes for resale pursuant to Section 5 hereof. Subscriber hereby agrees that the Subscription Agreement, as well as the nature of
Subscriber’s obligations hereunder, may be disclosed in any public announcement or disclosure required by the Commission and in any registration statement, proxy statement, consent solicitation statement or any other Commission filing to be
filed by the Company in connection with the issuance of the Subscribed Notes contemplated by this Subscription Agreement and/or the Transaction, in each case without the Subscriber’s prior written consent. 

i. This Subscription Agreement may not be amended, modified, waived or terminated except by an instrument in writing, signed by
each of the parties hereto, BBAI and BigBear; provided, that this Subscription Agreement may be amended, modified, waived or terminated with the written consent of the Company, BBAI, BigBear and the holders then committed to purchase a
majority of the Aggregate Subscribed Notes to be purchased at the Closing, including each holder (which includes Subscriber, its affiliates and accounts and funds controlled or managed by Subscriber or its affiliates) then committed to purchase at
least $25,000,000 of Subscribed Notes (or, if after the Closing, the Company and the holders then holding a majority of the then outstanding Aggregate Subscribed Notes, including each holder (which includes Subscriber, its affiliates and accounts
and funds controlled or managed by Subscriber or its affiliates) of then outstanding Subscribed Notes with an aggregate principal of at least $25,000,000) pursuant to this Subscription Agreement and the Other Subscription Agreements (collectively,
the “Required Subscriber”); provided further, that Section 4, this Section 8(i), and Section 8(k) of this Subscription Agreement may not be
amended, terminated or waived in a manner that is material and adverse to the Placement Agent without the written consent of the Placement Agent. Upon the effectuation of such waiver, modification, amendment or termination with the consent of the
Required Subscriber (and if required, the Placement Agent) in conformance with this Section 8(i), such amendment, modification, waiver or termination shall be binding on the Subscriber and effective as to all of this
Subscription Agreement. The Company shall promptly give written notice thereof to Subscriber if Subscriber has not previously consented to such amendment, modification, waiver or termination in writing; provided that the failure to give such notice
shall not affect the 

  
 25 













 
validity of such amendment, modification, waiver or termination. Notwithstanding anything to the contrary herein, (i) any amendment, modification or waiver that has a disproportionate effect
on Subscriber (considered apart from any disproportionate effect owing to the aggregate principal amount of the Subscribed Notes held by such Subscriber) relative to any of the Other Subscribers shall require the consent of Subscriber, (ii) any
amendment to Section 3(h), Section 5 or Section 6 of this Subscription Agreement shall require the consent of Subscriber and (iii) any amendment, modification or
other change that alters the Purchase Price shall require the consent of Subscriber. 
 j. This Subscription Agreement
constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties hereto, with respect to the subject matter hereof, except that any confidentiality
agreement with respect to Subscriber or its affiliates shall remain in full force and effect following the amendment, modification, waiver or termination of this Subscription Agreement. 

k. Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the
parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and
be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns. The parties hereto acknowledge and agree that the Placement Agent is an express third-party beneficiary of its express rights in
Section 3, Section 4, Section 8(i) and this Section 8(k) of this Subscription Agreement. The parties hereto acknowledge and agree that BigBear
and BBAI (each an express third-party beneficiary) shall be entitled to specifically enforce Subscriber’s obligation to fund the Purchase Price and the provisions of this Subscription Agreement on the terms and subject to the conditions set
forth in this Subscription Agreement. Each of the parties hereto shall be entitled to seek and obtain equitable relief, without proof of actual damages, including an injunction or injunctions or order for specific performance to prevent breaches of
this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement to cause Subscriber to fund the Purchase Price and cause the Closing to occur if the conditions in Section 2 of
this Subscription Agreement have been satisfied or, to the extent permitted by applicable law, waived by the applicable party entitled to waive any such condition. Each party hereto further agrees that none of the parties hereto or the Placement
Agent shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 8(k), and each party hereto irrevocably waives any
right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. 
 l. If any
provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall
continue in full force and effect. Prior to or at the Closing, Subscriber shall deliver to the Company a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. 
 m. This Subscription Agreement may be executed and delivered in one or more
counterparts (including by electronic mail, in .pdf or any other form of electronic delivery (including any electronic signature complying with U.S. federal ESIGN Act of 2000)) and by different parties in separate counterparts, with the same effect
as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement. 

  
 26 













 n. The parties hereto agree that irreparable damage would occur in the event
that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto, the Placement Agent, BBAI and BigBear shall be
entitled to seek an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy
to which such party is entitled to seek at law, in equity, in contract, in tort or otherwise. The parties hereto further agree not to assert that a remedy of specific enforcement pursuant to this Section 8(n) is
unenforceable, invalid, contrary to applicable law or inequitable for any reason and to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate. In connection with any action for which
BBAI or BigBear is entitled to an award of money damages, each of the Company and Subscriber agrees that such damages, to the extent payable by such party, shall include, without limitation, damages related to the cash consideration that is or was
to be paid to BBAI or BigBear or its equityholders under the Merger Agreement and/or this Subscription Agreement, and such damages are not limited to an award of
out-of-pocket fees and expenses related to the Merger Agreement and this Subscription Agreement. The parties acknowledge and agree that this
Section 8(n) is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Subscription Agreement. 

o. This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of New York,
without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state. 

p. EACH PARTY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING
OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH
RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A
TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER
SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT. 

  
 27 













 q. The parties agree that all disputes, legal actions, suits and proceedings
arising out of or relating to this Subscription Agreement must be brought exclusively in the state courts of New York or in the federal courts located in the state and county of New York (collectively the “Designated Courts”). Each
party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this subscription agreement may be brought in any other forum. Notwithstanding the foregoing, a final
judgement in any such action may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each party hereby irrevocably waives all claims of immunity from jurisdiction and any objection which such party may
now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an
improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 8(a) of this Subscription Agreement shall be
effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above. 

r. This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon,
arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought against the entities that are expressly named as parties hereto and then only with respect to
the specific obligations set forth herein with respect to such party. No past, present or future director, officer, employee, incorporator, manager, member, partner, stockholder, affiliate, agent, attorney or other representative of any party hereto
or of any affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities of any party hereto under this Subscription Agreement or for any claim, action, suit or other legal
proceeding based on, in respect of or by reason of the transactions contemplated hereby. 
 s. The Company shall, by 9:00
a.m., Eastern Time, on the first (1st) Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on
Form 8-K (collectively, the “Disclosure Document”) disclosing, to the extent not previously publicly disclosed, all material terms of the transactions contemplated hereby (and by the Other
Subscription Agreements), the Transaction and any other material, nonpublic information that the Company has provided to Subscriber at any time prior to the filing of the Disclosure Document. From and after the issuance of the Disclosure Document,
to the actual knowledge of the Company, Subscriber shall not be in possession of any material, non-public information received from the Company or any of its officers, directors or employees or the Placement
Agent. Notwithstanding the foregoing or anything contained to the contrary in Section 8(c), the Company shall not publicly disclose the name of Subscriber or any affiliate or investment advisor of Subscriber, or include the
name of Subscriber or any affiliate or investment advisor of Subscriber in any press release or in any filing with the Commission or any regulatory agency or trading market, without the prior written consent (including by e-mail) of Subscriber, except as required by the federal securities laws, rules or regulations and to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the
Commission or regulatory agency or under Nasdaq regulations, in which case the Company shall provide Subscriber with reasonable prior written notice (including by e-mail) of such permitted disclosure, and
shall reasonably consult with Subscriber regarding such disclosure. Subject to the limitations of the following sentence, Subscriber hereby consents to the publication and disclosure in any Form 8-K filed by
the Company with the Commission, in any filing with the Commission made in connection with the Merger Agreement and the Transaction, including any proxy 

  
 28 













 
statement, prospectus or registration statement related thereto or any other filing with the Commission pursuant to applicable securities laws, of Subscriber’s name and identity and the
nature of Subscriber’s commitments, arrangements and understandings under and relating to this Subscription Agreement and, if deemed required or appropriate by the Company, a copy of this Subscription Agreement. Any such disclosure under the
foregoing two sentences shall be made only after the Company as soon as practicable notifies the Subscriber of such requirement to disclose (except where prohibited by applicable law, legal process or regulatory request) so that the Subscriber (or
its applicable affiliate) may seek a protective order or other appropriate remedy prior to such disclosure. The Company shall provide a draft of any proposed disclosures under this Section 8(s) to subscriber reasonably in
advance of the release of such disclosures, but in no event less than one Business Day prior to release, and shall consider in good faith any revisions to such disclosure proposed by Subscriber. Notwithstanding the foregoing or anything contained to
the contrary in Section 8(c), the Company may make disclosures to an auditor or governmental or regulatory authority pursuant to any routine investigation, inspection, examination or inquiry without providing the Subscriber
with any notification thereof, unless the Subscriber is the subject of any such investigation, inspection, examination or inquiry (in which case the preceding sentence shall govern) 

t. The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other
Subscriber or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber under this Subscription Agreement or any other investor under
the Other Subscription Agreements. The decision of Subscriber to purchase Subscribed Notes pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber or any other investor and independently of any
information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any of its subsidiaries which may have
been made or given by any Other Subscriber or investor or by any agent or employee of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber or investor (or any
other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto or thereto, shall be
deemed to constitute Subscriber and other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and other investors are in any way acting in concert or as a group with
respect to such obligations or the transactions contemplated by the this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its
investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Notes or enforcing its rights under this Subscription Agreement. Subscriber shall be entitled to
independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber or investor to be joined as an additional party in any
proceeding for such purpose.

Section 2.04 Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company
by the manual, facsimile or other electronic signature of one of its Officers. 
 At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company
Order shall authenticate and deliver such Notes, without any further action by the Company hereunder. 
 Only such Notes as shall bear
thereon a certificate of authentication substantially in the form set forth on the Form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as
provided by Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be
conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture. 

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have
been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer of the Company;
and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such person was not such an
Officer. 
 Section 2.05 Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. The
Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within
a reasonable period of time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with Section 4.02. 
 Upon surrender for registration of transfer of
any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such legends as may be required by this Indenture. 

  
 15 













 Notes may be exchanged for other Notes of any authorized denominations and of a like
aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the
Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Trustee or Note Registrar
and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 

No service charge shall be imposed on a Holder by the Company, the Trustee, the Note Registrar, any
co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or
transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or
registration of transfer. 
 None of the Company, the Trustee, the Note Registrar or any co-Note
Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a
portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 0. 
 All Notes issued upon any
registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such
registration of transfer or exchange. 
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, subject to the fourth paragraph from the end of Section 2.05(d), all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or
the nominee of the Depositary. Each Global Note shall bear the legend required on a Global Note set forth in Exhibit A hereto. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note
shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the Applicable Procedures. 

(c) Every Note that bears or is required under this Section 2.05(c) to bear the Restrictive Legend (together with any Common Stock issued
upon conversion of the Notes that is required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c)
(including the legend set forth below) or Section 2.05(d) (including the legend set forth therein), as applicable, unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of
each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any
sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 

  
 16 













 Each Global Note shall bear a legend in substantially the following form (the
“Restrictive Legend”) (or any similar legend, not inconsistent with this Indenture, required by the Depositary for such Global Note): 

THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE (NOTWITHSTANDING THE FOREGOING, THIS SECURITY AND THE COMMON STOCK, IF ANY,
ISSUABLE UPON CONVERSION OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES). BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER
AGREES FOR THE BENEFIT OF BIGBEAR.AI HOLDINGS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR
AFTER THE ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT AND IS EFFECTIVE AT THE TIME OF
SUCH TRANSFER, OR 
 (C) TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH
RULE 144A UNDER THE SECURITIES ACT, OR 
 (D) PURSUANT TO OFFERS AND SALES TO
NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT; OR 

(E) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(E)
ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

NO AFFILIATE (AS DEFINED IN RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY OR PERSON THAT HAS BEEN AN AFFILIATE (AS DEFINED IN RULE 144
UNDER THE SECURITIES ACT) OF THE COMPANY DURING THE IMMEDIATELY PRECEDING THREE MONTHS MAY PURCHASE, OTHERWISE ACQUIRE OR HOLD THIS SECURITY OR A BENEFICIAL INTEREST HEREIN. 

  
 17 













 Any Note (or security issued in exchange or substitution therefor) (i) as to which such
restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to
be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Note for
exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restrictive Legend required by this
Section 2.05(c) and shall not be assigned (or deemed assigned) a restricted CUSIP number. The Restrictive Legend set forth above and affixed on any Note will be deemed, in accordance with the terms of the certificate representing such Note, to
be removed therefrom upon the Company’s delivery to the Trustee of written notice to such effect, without further action by the Company, the Trustee, the Holder(s) thereof or any other Person; at such time, such Note will be deemed to be
assigned an unrestricted CUSIP number as provided in the certificate representing such Note; provided, however, if such Note is a Global Note and the Depositary thereof requires a mandatory exchange or other process to cause such Global Note to be
identified by an unrestricted CUSIP number in the facilities of such Depositary, then the Company will effect such exchange or procedures as soon as reasonably practicable. Without limiting the generality of any other provision of this Indenture,
the Trustee will be entitled to receive an instruction letter from the Company before taking any action with respect to effecting any such mandatory exchange or other process. The Company and the Trustee reserve the right to require the delivery of
such legal opinions, certifications or other evidence as may reasonably be required in order to determine that any proposed transfer of any Note is being made in compliance with the Securities Act and applicable state securities laws. 

The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which any of the conditions set forth
in clause (i) through (iii) of the first sentence of the immediately preceding paragraph have been satisfied, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged
therefor shall not bear the Restrictive Legend specified in this Section 2.05(c) and shall not be assigned (or deemed assigned) a restricted CUSIP number. 

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may
not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph. 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as
depositary for the Global Notes and a successor depositary is not appointed within ninety (90) days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within
ninety (90) days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall
execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner
in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global
Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.


  
 18 













 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately
preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee, the Paying Agent, the Conversion Agent
or any other agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or
reviewing any records relating to such beneficial ownership interests. 
 Neither the Company nor the Trustee shall have any responsibility
or liability for any act or omission of the Depositary. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered
Holder(s) (which shall be the Depositary or its nominee in the case of a Global Note). 
 The rights of beneficial owners in any Global Note
shall be exercised only through the Depositary subject to the Applicable Procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members,
participants and any beneficial owners. 
 (d) Any stock certificate representing Common Stock issued upon conversion of a Note shall bear a
legend in substantially the following form (unless such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such
transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of a Note that has been transferred pursuant to a
registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision
then in force under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock): 

  
 19 













 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE (NOTWITHSTANDING THE FOREGOING, THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN
ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES). BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER AGREES FOR THE BENEFIT OF BIGBEAR.AI HOLDINGS, INC. (THE “COMPANY”) THAT IT WILL
NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE ISSUE DATE OF THE NOTES UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH
SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT AND IS EFFECTIVE AT THE TIME OF
SUCH TRANSFER, OR 
 (C) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR
OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT; OR 
 (D) PURSUANT TO AN EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.  
 PRIOR TO THE REGISTRATION
OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE
REQUIRED IN ORDER FOR THE COMPANY TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 Any such Common Stock (i) as to which such restrictions on transfer shall have
expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or
(iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for
exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by
this Section 2.05(e). 
 (e) Any Note or Common Stock issued upon conversion or exchange of a Note that is repurchased or owned by the
Company or any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months immediately preceding) may not be resold by the Company or such Affiliate (or such Person, as the case may be) unless
registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted
security” (as defined under Rule 144). 

  
 20 













 (f) Notwithstanding anything contained herein to the contrary, neither the
Trustee nor the Note Registrar shall be responsible for ascertaining whether any transfer complies with the registration provisions of, or exemptions from, the Securities Act, applicable state securities laws or other applicable law. 

Section 2.06 Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen,
the Company in its discretion may execute, and upon receipt of a Company Order, the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the
Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the
Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required
repurchase or is about to be converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or
convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable,
to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or
theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent of the destruction, loss or theft of such Note and of the ownership thereof. 

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with
respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with
respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

Section 2.07 Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form
of the Physical Notes but 

  
 21 













 
with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the
Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company
pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes upon the written request of the Company. Such
exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as
Physical Notes authenticated and delivered hereunder. 
 Section 2.08 Cancellation of Notes Paid, Converted, Etc. The Company
shall cause all Notes surrendered for the purpose of payment at maturity, repurchase upon a Fundamental Change, registration of transfer or exchange or conversion (other than any Notes exchanged pursuant to Section 14.12), if surrendered to any
Person that the Company controls other than the Trustee, to be surrendered to the Trustee for cancellation and they will no longer be considered outstanding under this Indenture upon their payment at maturity, registration of transfer or exchange or
conversion. All Notes delivered to the Trustee shall be canceled promptly by it. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise expressly permitted by any of the provisions of this Indenture, no Notes
shall be authenticated in exchange for any Notes surrendered to the Trustee for cancellation. The Trustee shall dispose of canceled Notes in accordance with its customary procedures. After such cancellation, the Trustee shall deliver a certificate
of such cancellation to the Company, at the Company’s written request in a Company Order. The Company may not issue new Notes to replace Notes that have been paid or that have been delivered to the Trustee for cancellation. 

Section 2.09 CUSIP and ISIN Numbers. The Company in issuing the Notes may use CUSIP and ISIN numbers (if then generally in use),
and, if so, the Trustee shall use CUSIP and ISIN numbers in all notices issued to Holders as a convenience to such Holders; provided that the Trustee shall have no liability for any defect in the CUSIP and ISIN numbers as they appear on any Note,
notice or elsewhere and that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers
printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers. 

Section 2.10 Additional Notes; Repurchases. The Company may, at any time and from time to time without the consent of the Holders,
reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, the issue price and interest accrued prior to the issue date of such additional Notes
and, if applicable, restrictions on transfer of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income
tax or securities laws purposes or would cause the Notes initially issued hereunder to be subject to an extended time period for restrictions on transfer, such additional Notes shall have one or more separate CUSIP, ISIN or other identifying
numbers. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such
matters, in addition to those required by Sections 10.05 and 17.05, as the Trustee shall reasonably request. In addition, the Company may, without the consent of Holders, and directly or indirectly (regardless of whether such Notes are surrendered
to the Company), repurchase Notes in the open market or otherwise, whether by the 

  
 22 













 
Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements or otherwise, including by cash-settled swaps or other
derivatives. The Company may, at its option, reissue, resell, hold or surrender to the Trustee for cancellation in accordance with Section 2.08 any Notes that the Company may repurchase, in the case of a reissuance or resale; provided
that if any such reissued or resold Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax or securities law purposes, such reissued or resold Notes shall have one or more separate CUSIP numbers. Any Notes that
the Company may repurchase shall be considered outstanding for all purposes under this Indenture (other than, at any time when such Notes are held by the Company or any of its Subsidiaries or its Affiliates, for the purpose of determining whether
Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture) unless and until such time the Company surrenders them to the Trustee for cancellation in accordance
with Section 2.08 and, upon receipt of a written order from the Company, the Trustee shall cancel all Notes so surrendered. 
 ARTICLE 3

 SATISFACTION AND DISCHARGE 

Section 3.01 Satisfaction and Discharge. This Indenture and the Notes shall upon request of the Company contained in an
Officer’s Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments reasonably requested by the Company acknowledging satisfaction and discharge of this Indenture and the Notes,
when (a) (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the Trustee for
cancellation; or (ii) after the Notes have (x) become due and payable, whether on the Maturity Date, on any Fundamental Change Repurchase Date or otherwise and/or (y) been converted (and the related consideration due upon conversion
has been determined), the Company has deposited with the Trustee cash and/or has delivered to Holders shares of Common Stock, as applicable, (in the case of Common Stock, solely to satisfy the Company’s Conversion Obligation) sufficient,
without consideration of reinvestment, to pay all of the outstanding Notes and all other sums due and payable under this Indenture or the Notes by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and
an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture and the Notes have been complied with. Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 
 ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01 Payment of Principal and Interest. The Company covenants and agrees that it will pay or cause to be paid the
principal (including the Fundamental Change Repurchase Price, if applicable) and premium, if any, of the Settlement Amounts owed upon conversion of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in
the manner provided herein and in the Notes. 
 Notwithstanding anything to the contrary contained in this Indenture, the Company or Paying
Agent may, to the extent it is required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal, premium or Interest or Defaulted Amounts payments hereunder. 

  
 23 













 Section 4.02 Maintenance of Office or Agency. The Company will maintain in the
contiguous United States an office or agency (which may be an office of the Trustee or an affiliate of the Trustee) where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase
(“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be made. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made at the Corporate Trust Office. 
 The Company may also from time to time
designate as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations;
provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the contiguous United States for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or
agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and
Conversion Agent and the Corporate Trust Office as a place where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (if applicable) or for conversion and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be made; provided that no office of the Trustee shall be a place for service of legal process on the Company.

Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders; 

(ii) that it will give the Trustee prompt written notice of any failure by the Company to make any payment of the principal

Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or such accrued and
unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be made in
immediately available funds and received by the Paying Agent by 11:00 a.m., New York City time, on such date.

benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest, if any, so becoming due and will promptly notify the Trustee in writing of
any failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due
and payable. 
 (c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of
obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04,

due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to
the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust and the Trustee shall have no further liability with respect to such funds; and the Holder of such
Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee, the Conversion Agent or such Paying Agent with respect to such trust money, and all liability of the Company as

Trustee or any Holder any information for which the Company is requesting (assuming such request has not been denied), or has received, confidential treatment from the Commission, or any correspondence with the Commission. Any such document or
report that the Company files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be delivered to the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the
EDGAR system (or such successor); provided that the Trustee shall have no obligation to determine whether such documents or reports have been filed via the EDGAR system. 

(c) Delivery of the reports, information and documents described in subsection (b) above to the Trustee is for informational purposes

(g) default by the Company or any Significant Subsidiary of the Company with respect to any mortgage, agreement or other instrument under which

whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity or (ii) constituting a failure to pay the principal of any such

 27 













 (h) the Company or any Significant Subsidiary shall commence a voluntary case or other

appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking

liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of sixty
(60) consecutive days. 
 Section 6.02 Acceleration; Rescission and Annulment. If one or more Events of Default shall have
occurred and be continuing, then, and in each and every such case (other than an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company), unless the principal of all of the Notes shall have already
become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given
by Holders), may declare 100% of the principal of, premium, if any, of and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately
due and payable. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and
shall automatically be immediately due and payable. 
 The immediately preceding paragraph, however, is subject to the conditions that if,
at any time after the principal or interest of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall
pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue
installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to
Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the uncured nonpayment of the
principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately
succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and
annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or 

  
 28 













 
rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase
Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay and/or deliver, as the case may be, the consideration due upon conversion of the Notes.

 Section 6.03 Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent
the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall after the occurrence of such an Event of Default consist exclusively of the
right to receive Additional Interest on the Notes at a rate equal to 2.00% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such Event of Default first occurs
and ending on the earlier of (x) the date on which such Event of Default is cured or validly waived in accordance with this Article 6 and (y) the three hundred sixtieth (360th) day
immediately following, and including, the date on which such Event of Default first occurs. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes and
shall accrue on all outstanding Notes from, and including, the date on which the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) first occurs to, and including, the three
hundred sixtieth (360th) day thereafter (or such earlier date on which such Event of Default is cured or validly waived in accordance with this Article 6). On the three hundred sixty-first
(361st) day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) is not cured or validly
waived in accordance with this Article 6 prior to such three hundred sixty-first (361st) day), such Additional Interest shall cease to accrue and the Notes shall be immediately subject to
acceleration as provided in Section 6.02. The provisions of this paragraph will not affect the rights of Holders in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set
forth in Section 4.06(b). In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company has elected to make such payment but does not pay the Additional
Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 
 In order to elect to pay
Additional Interest as the sole remedy during the first three hundred sixty (360) days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee
and the Paying Agent in an Officer’s Certificate of such election on or before the open of business on the Business Day immediately succeeding the date on which such Event of Default first occurs. Upon the failure to timely give such notice,
the Notes shall be immediately subject to acceleration as provided in Section 6.02. The Officer’s Certificate under this Section 6.03 shall state (i) the amount of such Additional Interest that is payable and (ii) the date
on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such Officer’s Certificate, the Trustee may assume without inquiry that no such Additional Interest is
payable. 
 Section 6.04 Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b)
of Section 6.01 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and
interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under
Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the
Company or any other obligor upon the Notes, wherever situated. 

  
 29 













 In the event there shall be pending proceedings for the bankruptcy or for the reorganization
of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall
have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor, or to the creditors
or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid
interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the
Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under
Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in
the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and
including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any
such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled
to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
 Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or
to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 All rights of action and of asserting
claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, be for the ratable benefit of the Holders of the Notes. 
 In any proceedings brought by the Trustee (and in any
proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes
parties to any such proceedings. 

  
 30 













 In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee,
then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the
Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted. 
 Section 6.05 Application of
Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies,
upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

First, to the payment of all amounts due the Trustee, including its agents and counsel, under Section 7.06; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of any interest on, and
any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee)
payable upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Holders based on the aggregate principal amount of Notes held thereby; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal
and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and
unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and interest without preference or priority of principal over interest, or of interest
over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash
due upon conversion) and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company. 

Section 6.06 Proceedings by Holders. Except to enforce (x) the right to receive payment of principal (including, if
applicable, the Fundamental Change Repurchase Price), premium or interest when due, or (y) the right to receive payment or delivery of the consideration due upon conversion and/or the conversion mechanics, no Holder of any Note shall have any
right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof, as herein provided; 
 (b) Holders of at least 25% in aggregate
principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

  
 31 













 (c) such Holders shall have offered, and, if requested, provided, to the Trustee such
security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense to be incurred therein or thereby; 
 (d)
the Trustee for sixty (60) days after its receipt of such notice, request and offer of such security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 

(e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the
Holders of a majority of the aggregate principal amount of the Notes then outstanding within such sixty (60) day period pursuant to Section 6.09, 

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that
no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder (it being understood that the Trustee does not have an
affirmative duty to ascertain whether or not such actions or forbearances are prejudicial to any other Holder), or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except
in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled
to such relief as can be given either at law or in equity. 
 Notwithstanding any other provision of this Indenture and any provision of any
Note, each Holder shall have the contractual right to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on,
and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, and the contractual right to institute suit for the enforcement of any such payment
or delivery, as the case may be, on or after such respective dates, shall not be amended without the consent of each Holder. 

Section 6.07 Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether
for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by
law. 
 Section 6.08 Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, all
powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the
Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to
exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions
of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. The Trustee may
maintain a proceeding even if it does not possess any Notes or does not produce any Notes in the proceeding. 

  
 32 













 Section 6.09 Direction of Proceedings and Waiver of Defaults by Majority of
Holders. The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this
Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any
other Holder or that would involve the Trustee in personal liability or for which it has not received indemnity or security satisfactory to the Trustee against loss, liability or expense (it being understood that the Trustee does not have an
affirmative duty to determine whether any direction is prejudicial to any Holder). The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the
Holders of all of the Notes (x) waive any past Default or Event of Default hereunder and its consequences except any continuing defaults relating to (i) a default in the payment of the principal (including any Fundamental Change Repurchase
Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in
respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected; and (y) rescind any resulting acceleration of the Notes and its consequences

other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of

filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any
Holder for the enforcement of the payment

exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs;
provided that the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered, and if requested, provided to the Trustee
indemnity or security satisfactory to the Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or direction. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly
negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default that may have occurred: 
 (i) the duties and obligations of the Trustee shall be

on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in

event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred;

such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall
have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company; and 

(h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the
rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent.

faith in reliance on such Officer’s Certificate or Opinion of Counsel. 
 (c) The Trustee may consult with counsel and require an
Opinion of Counsel and any advice of such counsel or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in reliance on such advice or Opinion of

stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, judgment, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee shall determine in its reasonable judgment to make such further inquiry or investigation, it shall be entitled, at a reasonable time on any Business Day after reasonable
notice, to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation.

Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any Person authorized to sign an
Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

(h) The Trustee shall not be deemed to have notice of any Default or Event of Default (except in the case of a Default or Event of Default in
payment of scheduled principal of, premium, if any, or interest on, any Note) unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default or Event of Default (and
stating the occurrence of a Default or Event of Default) is actually received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture and states that it is a “Notice of Default”.

duties as set forth herein as a result of any inaccuracy or incompleteness.

authenticated and delivered by the Trustee in conformity with the provisions of this Indenture or any money paid to the Company or upon the Company’s direction under any provision of this Indenture. 

Section 7.04 Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any Paying Agent, any
Conversion Agent or Note Registrar (in each case, if other than an Affiliate of the Company), in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying
Agent, Conversion Agent or Note Registrar. 
 Section 7.05 Monies and Shares of Common Stock to Be Held in Trust. All monies and
shares of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common Stock held by the Trustee in trust hereunder need not be

Section 7.06 Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and
the Trustee shall be entitled to, compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in
writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this
Indenture in any capacity hereunder (including the compensation and the reasonable expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have
been caused by its gross negligence or willful misconduct as determined by a final order of a court of competent jurisdiction. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or
transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense (including attorneys’ fees) incurred without gross negligence or
willful misconduct on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, as determined by a final order of a court of competent jurisdiction, and arising out of or in
connection with the acceptance or administration of this Indenture or in any other capacity hereunder (whether such claims arise by or against the Company or a third person), including the reasonable costs and expenses of defending


  
 37 













 
themselves against any claim of liability in the premises or enforcing the Company’s obligations hereunder. The obligations of the Company under this Section 7.06 to compensate or
indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior lien to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except,
subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any
other liability or indebtedness of the Company. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture, the payment or conversion of the Notes and the earlier resignation or removal
of the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and
employees of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its
agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(h) or Section 6.01(i) occurs, the expenses and the compensation for the services are intended to constitute expenses
of administration under any bankruptcy, insolvency or similar laws. 
 Section 7.07 Officer’s Certificate as
Evidence. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting
any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and
established by an Officer’s Certificate delivered to the Trustee, and such Officer’s Certificate, in the absence of gross negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action
taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 7.08 Eligibility of Trustee.
There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least
$50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 7.09 Resignation or Removal of
Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company. Upon receiving such notice of resignation, the Company shall promptly notify all Holders and appoint a successor trustee by written
instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within sixty (60) days after the giving of such notice of resignation to the Company, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders and at the expense of the Company, petition
any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, subject to the provisions of
Section 6.11, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee. 

  
 38 













 (a) In case at any time any of the following shall occur: 

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign
after written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee shall become incapable of acting,
or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, 
 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written
instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.11, any Holder
who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(b) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with
Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten (10) days after notice to the Company of such nomination the Company objects thereto,
in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 

(c) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this
Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 

Section 7.10 Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights
and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights
and powers. Any trustee ceasing to act shall, nevertheless, retain a senior lien to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of
Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 

  
 39 













 No successor trustee shall accept appointment as provided in this Section 7.10 unless
at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of
appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of
such trustee hereunder to the Holders. If the Company fails to deliver such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered at the expense of
the Company. 
 Section 7.11 Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially
all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties
hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08.

 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or
in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however,
that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 7.12 Trustee’s Application for Instructions from the Company. Any application by the Trustee for
written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set
forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable to the Company for any
action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any officer
that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the
effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

 ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01 Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders.
Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee, as applicable, may, but shall not be required to, fix in advance of such solicitation, a date as the record date for
determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action. 

Section 8.02 Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and
Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06. 

Section 8.03 Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion
Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation
of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal (including any Fundamental Change Repurchase Price) of and (subject to
Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by
any notice to the contrary. The sole registered holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the
sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an
Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s
right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture. 

Section 8.04 Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of
Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Affiliate of the Company or any Subsidiary thereof shall be disregarded and deemed
not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible
Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the
Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by
the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and


  
 41 













 
identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be
entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

Section 8.05 Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence
to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as
concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution
therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

any directions to the Trustee permitted under this Indenture, or to consent to the waiving of any Default or Event of Default hereunder (in each case, as permitted under this Indenture) and its consequences, or to take any other action authorized to
be taken by Holders pursuant to any of the provisions of Article 6; 
 (b) to remove the Trustee and nominate a successor trustee

Such notice shall also be delivered to the Company. Such notices shall be delivered not less than twenty (20) nor more than ninety (90) days prior to the date fixed for the meeting. 

Any meeting of Holders shall be valid without notice if the Holders of all Notes then outstanding are present in person or by proxy or if

 Section 9.03 Call of Meetings by Company or Holders. In case at any time the
Company or the Holders of at least twenty-five (25%) of the aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have delivered the notice of such meeting promptly and in any event within twenty (20) days after receipt of such request, then the Company or such Holders may determine the time

Section 9.05 Regulations. Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations

certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 8.04, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each
$1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting
to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of
Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not
constituting a quorum, and the meeting may be held as so adjourned without further notice.

written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of
the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was delivered as provided in

one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 

  
 43 













 Any record so signed and verified shall be conclusive evidence of the matters therein
stated. 
 Section 9.07 No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be deemed or construed to
authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or
to the Holders under any of the provisions of this Indenture or of the Notes. Nothing contained in this Article 9 shall be deemed or construed to limit any Holder’s actions pursuant to the applicable procedures of the Depositary so long as the
Notes are Global Notes.

(n) to make any change to comply with rules of the Depositary, so long as such change does not adversely affect the rights of any Holder, as

 Upon the written request of the Company and subject to
Section 10.05, the Trustee is hereby authorized to, and shall, join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee
shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed by the Company and the Trustee without the
consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 10.02 Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the
Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or
exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s sole expense, may from time to time and at any time enter into an indenture or indentures supplemental
hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture, any supplemental indenture or the Notes or of modifying in any manner the rights of the Holders;

respective due dates expressed or provided for in the Notes or this Indenture; 
 (i) make any change in this Article 10 that requires
each Holder’s consent or in the waiver provisions in Section 6.02 or Section 6.09; or 
 (j) provide for the issuance of
additional Notes except as permitted herein. 
 Upon the written request of the Company, and upon the delivery to the Trustee of evidence of
the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be
sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such
notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

Section 10.03 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and
the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes. 
 Section 10.04 Notation on Notes. Notes authenticated and
delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation as to any matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and
executed by the Company, authenticated, upon receipt of a Company Order, by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes then outstanding, upon
surrender of such Notes then outstanding. 
 Section 10.05 Evidence of Compliance of Supplemental Indenture to Be Furnished
Trustee. In addition to the documents required by Section 17.05, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with
the requirements of this Article 10 and is permitted or authorized by this Indenture and such Opinion of Counsel shall include a customary legal opinion stating that such supplemental indenture is the valid and binding obligation of the
Company, subject to customary exceptions and qualifications.

 ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01 Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, the Company shall
not consolidate with, merge with or into, or sell, convey, transfer or lease, all or substantially all of the consolidated assets of the Company and the Company’s Subsidiaries, taken as a whole, to another Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the
Company under the Notes and this Indenture; 
 (b) immediately after giving effect to such transaction, no Event of Default shall have
occurred and be continuing under this Indenture; and 
 (c) if the Company is not the Successor Company, the Successor Company shall have
delivered to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease complies with this Indenture and that such supplemental indenture is authorized or
permitted by this Indenture and an Opinion of Counsel stating that the supplemental indenture is the valid and binding obligation of the Successor Company, subject to customary exceptions and qualifications. 

For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of
one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated
basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 11.02 Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company (if other than the Company), by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of the due and punctual payment of the principal
of and accrued and unpaid interest on all of the Notes, the due and punctual delivery and/or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the consolidated assets of the Company and the Company’s
Subsidiaries, taken as a whole, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, and the Company shall be discharged from its obligations under the Notes and this Indenture
(except in the case of a lease of all or substantially all of the consolidated assets of the Company and the Company’s Subsidiaries, taken as a whole). Such Successor Company thereupon may cause to be signed, and may issue either in its own
name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject
to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers
of the Company to the Trustee for authentication, and any Notes that such Successor 

  
 47 













 
Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture
as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or
transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner
prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations
under this Indenture and the Notes. 
 In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in
phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 11.03
Opinion of Counsel to Be Given to Trustee. The Company shall deliver, or cause to be delivered, to the Trustee an Officer’s Certificate and an Opinion of Counsel, each to the effect that such consolidation, merger, combination, sale,
lease or other transfer or disposition complies with the requirements of this Indenture. 
 ARTICLE 12 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, 

OFFICERS AND DIRECTORS 

Section 12.01 Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and
unpaid interest on, or the payment or delivery of consideration due upon conversion of, any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in
this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such,
past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

 ARTICLE 14 

CONVERSION OF NOTES 

Section 14.01 Conversion Privilege. Subject to and upon compliance with the provisions of this Article 14, each Holder of a
Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the close of business on the second
Scheduled Trading Day immediately preceding the Maturity Date, at an initial conversion rate of 86.9565 shares of Common Stock (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per $1,000 principal
amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the “Conversion Obligation”). 

  
 48 













 Section 14.02 Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to this Section 14.02, Section 14.07(a) and Section 14.14(b), upon conversion of any Note, the Company shall pay or
deliver, as the case may be, to the converting Holder no later than two (2) Business Days following the applicable conversion of the Notes, (A) in respect of each $1,000 principal amount of Notes being converted, shares of Common Stock,
together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Physical Settlement”) as set forth in this Section 14.02 and
(B) other than in connection with any Mandatory Conversion, the Interest Make-Whole Amount. The Company shall use the Physical Settlement Method for all conversions. 

(i) The shares of Common Stock and cash the Company shall pay and/or deliver, as the case may be, in respect of any conversion
of Notes (the “Settlement Amount”) shall be computed as follows in respect of each $1,000 principal amount of Notes being converted: (A) a number of shares of Common Stock equal to the Conversion Rate in effect on the
Conversion Date (plus cash in lieu of any fractional share of Common Stock issuable upon conversion); plus (B) other than in connection with any Mandatory Conversion, the Interest Make-Whole Amount, (x) if the arithmetic average of the
Daily VWAPs for the ten (10) Trading Days immediately preceding the Conversion Date (the “Average VWAP”) equals or exceeds $11.50 per share, a number of shares of Common Stock determined by dividing the Interest Make-Whole
Amount by the Average VWAP (plus cash in lieu of any fractional shares of Common Stock); or (y) if the Average VWAP is less than $11.50 per share, solely in the form of cash. 

(ii) Notwithstanding the foregoing, if in connection with any conversion of a Note (i) the Conversion Rate is eligible for
adjustment in accordance with Section 14.14 hereof and (ii) the Holder is entitled to receive the Interest Make-Whole Amount with respect to such Note, then one, but not both, of (A) the Conversion Rate adjustment in accordance with
Section 14.14 and (B) the payment by the Company of the Interest Make-Whole Amount, shall apply, in each case according to which of (A) or (B) would result in more consideration being paid and/or delivered to the Holder in respect of
such conversion. 
 (b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above,
such Holder shall (i) in the case of a Global Note, comply with the Applicable Procedures of the Depositary in effect at that time and, if required, pay funds equal to the interest payable on the next Interest Payment Date to which such Holder
is not entitled as set forth in Section 14.02(h) and, if required, pay all transfer or similar taxes, if any, pursuant to Section 14.02(e) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an
irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount
of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered,
(2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer
documents, (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (5) if required, pay all transfer or similar taxes, if any,
pursuant to Section 14.02(e). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to
any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance
with Section 15.03. Notwithstanding anything to the contrary contained herein, to the extent that an indirect holder of a Global Note held indirectly through a participant submits irrevocable instructions to convert any portion of such Note,
such Holder shall be deemed for purposes of Regulation SHO to have converted the applicable portion of such Note at the time of delivery of such instructions, regardless of when shares of Common Stock are delivered to such Holder or its participant.


  
 49 













 If more than one Note shall be surrendered for conversion at one time by the same Holder,
the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (ii) above. Except as set forth in Section 14.07(a) and Section 14.14(b), the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation on the second (2nd) Business Day immediately following the relevant Conversion Date. Notwithstanding the foregoing, with respect to the
Company’s satisfaction of its Conversion Obligation through Physical Settlement for which the relevant Conversion Date occurs after the Regular Record Date immediately preceding the Maturity Date, the settlement shall occur on the Maturity
Date. If any shares of Common Stock are due to a converting Holder, the Company shall issue or cause to be issued, and deliver (if applicable) to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, the full number of
shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary or on the Transfer Agent’s books if the shares of Common Stock are not then held through the facilities of DTC, in satisfaction of the
Company’s Conversion Obligation. 
 (d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the
Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note,
without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by
law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately
preceding sentence. 
 (f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock
issued upon the conversion of any Note as provided in this Article 14. 
 (g) Upon the conversion of an interest in a Global Note, the
Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected
through any Conversion Agent other than the Trustee. 

  
 50 













 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and
unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any,
to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding
the foregoing, if Notes are converted after the close of business on a Regular Record Date but prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes as of the close of business on such Regular Record
Date will receive the full amount of interest payable on such Notes on such Interest Payment Date notwithstanding the conversion. However, Notes surrendered for conversion during the period from the close of business on any Regular Record Date to
the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted on the corresponding Interest Payment Date (regardless of whether the converting
Holder was the Holder of record on the corresponding Regular Record Date); provided that no such payment shall be required (1) for conversions following the close of business on the Regular Record Date immediately preceding the Maturity
Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has
selected a Mandatory Conversion Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts
exist at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date and any Fundamental Change Repurchase Date described in clause
(2) above shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date in cash regardless of whether their Notes have been converted and/or repurchased, as applicable, following such Regular Record
Date. 
 (i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of
record as of the close of business on the relevant Conversion Date. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. Prior to conversion of a Holder’s Note, such Holder (in such
capacity) shall not have any rights as a stockholder of the Company. 
 (j) The Company shall not issue any fractional share of Common Stock
upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date. 

Section 14.03 Company’s Mandatory Conversion Option. 

(a) On or after [ ], 2022 and prior to the close of business on [ ], 20261, the Company
may, at its option, elect to convert the original principal amount of the Notes in whole but not in part if (x) the Last Reported Sale Price of the Common Stock for at least twenty (20) Trading Days (whether or not consecutive) during the
period of thirty (30) consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter (the “Mandatory Conversion Determination Date”) is greater than or equal to 130% of the
Conversion Price on each applicable Trading Day and (y) the 30-Day ADTV ending on, and including, the Mandatory Conversion Determination Date is greater than or equal to $3,000,000 for the first two
(2) years after the initial issuance of the Notes hereunder and $2,000,000 thereafter (the “Company Mandatory Conversion Condition”). 

 

	1 	 NTD: To be the fifth Business Day after the last quarter end before the Maturity Date. 



  
 51 













 (b) To exercise the Company Mandatory Conversion Right, the Company will send notice of the
Company’s election (a “Mandatory Conversion Notice”) to Holders, the Trustee and the Conversion Agent no later than the fifth (5th) Business Day following the Mandatory Conversion Determination Date. 

Such Mandatory Conversion Notice must state: 

(i) that the Notes have been called for Mandatory Conversion, briefly describing the Company Mandatory Conversion Right under this Indenture;

 (ii) the Mandatory Conversion Date; 

(iii) the current Conversion Rate; 

(iv) the name and address of the Paying Agent and the Conversion Agent; and 

(v) the CUSIP and ISIN numbers, if any, of the Notes. 

(c) If the Company exercises the Company Mandatory Conversion Right in accordance with this Section 14.03, then a Conversion Date will
automatically, and without the need for any action on the part of any Holder, the Trustee or the Conversion Agent, be deemed to occur, with respect to each Note then outstanding, on the Mandatory Conversion Date. The Mandatory Conversion Date
will be a Business Day of the Company’s choosing that is no more than thirty (30), nor less than ten (10), Business Days after the Company sends the Mandatory Conversion Notice; provided that the Mandatory Conversion Date shall be no later than
the second Scheduled Trading Day prior to the Maturity Date. The Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the second (2nd)
Business Day immediately following the Mandatory Conversion Date. 
 (d) Each share of Common Stock delivered upon a Mandatory Conversion of
any Note will be a newly issued or treasury share and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim. If the Common Stock is then
listed on any securities exchange and has been registered on an effective registration statement with the Commission, then the Company will cause each share of Common Stock, when delivered upon a Mandatory Conversion of any Note, to be admitted for
listing on such exchange. Notwithstanding anything herein to the contrary, the Company (1) shall not be permitted to effect any Company Mandatory Conversion hereunder unless as of such Mandatory Conversion Date no Equity Conditions Failure then
exists and (2) shall not be required to pay any Interest Make-Whole Amount in connection with any Mandatory Conversion. 

Section 14.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the
following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange
offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes, as if they held a
number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

  
 52 













 (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution
on shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 
  





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Record Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share
combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Record Date or Effective Date, as applicable;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Record Date or Effective Date, as applicable, before giving effect to such dividend, distribution, share split or share combination;
and
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.

 Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on the
Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this
Section 14.04(a) is declared but not so paid or made, or any share split or combination of the type described in this Section 14.04(a) is announced but the outstanding shares of Common Stock are not split or combined, as the case may be,
the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines in good faith not to pay such dividend or distribution, or not to split or combine the outstanding shares of Common Stock, as the case
may be, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or combination had not been announced. 

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a
stockholders rights plan) entitling them, for a period of not more than forty-five (45) calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than
the average of the Last Reported Sale Prices of the Common Stock for the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate
shall be increased based on the following formula: 
  
 



 
 where, 

  
 53 














					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Record Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Record Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Record Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to (i) the aggregate price payable to exercise such rights, options or warrants, divided by (ii) the average of the Last Reported Sale Prices of the Common Stock over the ten
(10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 14.04(b) shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the open of business on the Record Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or
warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Record Date for such issuance had not occurred. 

For purposes of this Section 14.04(b), in determining whether any rights, options or warrants entitle the holders of Common Stock to
subscribe for or purchase shares of the Common Stock at a price per share that is less than such average of the Last Reported Sale Prices of the Common Stock for the ten (10) consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options
or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors in good faith. 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,
options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances (including share splits) as to which an adjustment was effected
pursuant to Section 14.04(a), Section 14.04(b) or Section 14.04(e), (ii) except as otherwise described in Section 14.11, rights issued pursuant to any stockholders rights plan of the Company then in effect, (iii) dividends
or distributions paid exclusively in cash as to which the provisions set forth in Section 14.04(d) shall apply, (iv) dividends or distributions of Reference Property in exchange for or upon conversion of the Common Stock in a Share
Exchange Event, and (v) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to
acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 

  
 54 













 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Record Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Record Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Record Date for such distribution;
and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors in good faith) of the Distributed Property with respect to each outstanding share of the Common Stock on the Record Date for such distribution.

 Any increase made under the portion of this Section 14.04(c) above shall become effective immediately
after the open of business on the Record Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not been declared.
If the Company issues rights, options or warrants to acquire Capital Stock or other securities that are exercisable only upon the occurrence of certain triggering events, the Company shall not adjust the conversion rate pursuant to the clauses above
until the earliest of these triggering events occurs. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as
defined above), then, in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed
Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the open of business on the Record Date for the
distribution. If the Board of Directors determines in good faith the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any
securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the Record Date for such distribution. 
 With respect to an adjustment pursuant to this Section 14.04(c)
where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or,
when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

 
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;


  
 55 














					
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of
Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first ten (10) consecutive Trading Day period after, and including, the Record
Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the
last Trading Day of the Valuation Period; provided that if the relevant Conversion Date occurs during the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of
Trading Days as have elapsed between the Record Date of such Spin-Off and the Conversion Date in determining the Conversion Rate. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Conversion Rate shall be immediately decreased, effective as of the date the Board of Directors determines in good faith not to pay or make such dividend or
distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or announced. 

For purposes of this Section 14.04(c) (and subject in all respect to Section 14.11), rights, options or warrants distributed by the
Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the
occurrence of a specified event or events (“Trigger Event”): 
 (i) are deemed to be transferred with such shares of the
Common Stock; 
 (ii) are not exercisable; and 

(iii) are also issued in respect of future issuances of the Common Stock, 

shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this
Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such
rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Record Date
with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event
of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a
distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made: 
 (1) in the case of any such
rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had
not been issued and the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or 

  
 56 













 
Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such
rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and 

(2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of Section 14.04(a),
Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the “Clause A
Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable
(the “Clause B Distribution”), 
 then, in either case, 

(1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or
distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(c) with respect to such Clause C Distribution shall then be made,
and 
 (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any
Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Record Date” of the Clause A Distribution and
the Clause B Distribution shall be deemed to be the Record Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding
immediately prior to the open of business on such Record Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such Record Date” within the meaning of
Section 14.04(b). 
 (d) If the Company pays or makes any cash dividend or distribution to all or substantially all holders of the
Common Stock, the Conversion Rate shall be increased based on the following formula: 
  
 



 
 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Record Date for such dividend or distribution;
			
	 CR1
	  	=	  	the Conversion Rate in effect immediately after the open of business on the Record Date for such dividend or distribution;
			
	 SP0
	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Record Date for such dividend or distribution; and
			
	 C
	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.


  
 57 













 Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of
business on the Record Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines in good faith not to make or pay such
dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon
the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for such cash dividend
or distribution. 
 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common
Stock that is subject to the then-applicable tender offer rules under the Exchange Act (other than an odd lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock
exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to
such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the tenth (10th) Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires (the
date such tender offer or exchange offer expires, the “Expiration Date”);
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the tenth (10th) Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors in good faith) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Expiration Date (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange
offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.


  
 58 













 The increase to the Conversion Rate under this Section 14.04(e) shall occur at the
close of business on the tenth (10th) Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that if the
relevant Conversion Date occurs during the ten (10) Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “ten (10)” or “tenth (10th)” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Expiration Date of such tender or exchange offer and the Conversion
Date in determining the Conversion Rate. In addition, if the Trading Day next succeeding the date such tender or exchange offer expires is after the tenth (10th) Trading Day immediately preceding,
and including, the date immediately preceding the relevant Conversion Date in respect of a conversion of Notes, references to “ten (10)” or “tenth (10th)” in the preceding
paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange
offer expires to, and including, the last Trading Day immediately preceding the relevant Conversion Date. 
 In the event that the Company
or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company is, or such Subsidiary is, permanently prevented by applicable law from consummating any such purchases,
or all such purchases are rescinded, then the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that
have been consummated. 
 (f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion
Rate adjustment becomes effective on any Record Date, and a Holder that has converted its Notes on or after such Record Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the
related Conversion Date as described under Section 14.02(i) based on an adjusted Conversion Rate for such Record Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment
relating to such Record Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend,
distribution or other event giving rise to such adjustment. 
 (g) Except as stated herein, the Company shall not adjust the Conversion Rate
for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, the Company from time to
time may increase the Conversion Rate by any amount for a period of at least twenty (20) Business Days if the Board of Directors determines in good faith that such increase would be in the Company’s best interest. In addition, the Company
may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire
shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note a notice of the increase at least fifteen (15) days
prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

  
 59 













 (i) Except as stated in this Indenture, the Company shall not adjust the Conversion Rate for
the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. For illustrative purposes only and
without limiting the generality of the preceding sentence, the Conversion Rate shall not be adjusted: 
 (i) upon the
issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common
Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares
pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 

(iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable
or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 

(iv) upon the repurchase of any shares of Common Stock pursuant to an open market share repurchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender or exchange offer of the nature described in Section 14.04(e); 

(v) solely for a change in the par value (or lack of par value) of the Common Stock; or 

(vi) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. 
 (k) Whenever the Conversion Rate is adjusted as herein
provided, the Company shall promptly deliver to the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without
inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a written notice of such adjustment of the Conversion Rate setting forth the adjusted
Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder (with a copy to the Trustee). Failure to deliver such notice shall not affect the legality
or validity of any such adjustment. 
 (l) For purposes of this Section 14.04, the number of shares of Common Stock at any time
outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include
shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

  
 60 













 (m) For the avoidance of doubt, the closing of the transactions contemplated by the BCA to
occur on the date of this Indenture shall not result in any adjustment of the Conversion Rate, Conversion Price or any other terms of the Notes. 

Section 14.05 Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported
Sale Prices or the Daily VWAPs over a span of multiple days, the Board of Directors shall make appropriate adjustments (without duplication in respect of any adjustment made pursuant to Section 14.04) to each to account for any adjustment to
the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Record Date, Effective Date or Expiration Date, as the case may be, of the
event occurs, at any time during the period when the Last Reported Sale Prices or the Daily VWAPs are to be calculated. 

Section 14.06 Shares to Be Fully Paid. The Company shall reserve, out of its authorized but unissued shares or shares held in
treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming the delivery of the maximum number of Additional Shares pursuant to Section 14.14). 

Section 14.07 Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the case of: 

(i) any recapitalization, reclassification or similar change of the Common Stock (other than changes in par value or resulting
from a subdivision or combination), 
 (ii) any consolidation, merger, combination or similar transaction involving the
Company, 
 (iii) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets
of the Company and the Company’s Subsidiaries, taken as a whole, or 
 (iv) any statutory share exchange, 

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Share Exchange Event”), then at and after the effective time of such Share Exchange Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right
to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the
Conversion Rate immediately prior to such Share Exchange Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference
Property that a holder of one share of Common Stock is entitled to receive) upon such Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or acquiring Person, as the case may be,
shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective
time of the Share Exchange Event (A) the Company or the successor or acquiring company, as the case may be, shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, in respect of the
Interest Make-Whole Amount upon conversion of Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash,
(II) any shares of Common Stock that the Company 

  
 61 













 
would have been required to deliver upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of
that number of shares of Common Stock would have been entitled to receive in such Share Exchange Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration
actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common
Stock. If the holders of the Common Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) the consideration due
upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.14), multiplied by
the price paid per share of Common Stock in such Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying such cash amount to converting Holders on the second
(2nd) Business Day immediately following the relevant Conversion Date. The Company shall notify in writing Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such
weighted average as soon as reasonably practicable after such determination is made. 
 If the Reference Property in respect of any Share
Exchange Event includes, in whole or in part, shares of common equity, such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is
possible to the adjustments provided for in this Article 14 with respect to the portion of the Reference Property consisting of such common equity. If, in the case of any Share Exchange Event, the Reference Property includes shares of stock,
securities or other property or assets (including any combination thereof), other than cash and/or cash equivalents, of a Person other than the Company or the successor or purchasing corporation, as the case may be, in such Share Exchange Event,
then such supplemental indenture shall also be executed by such other Person, if such other Person is an affiliate of the Company or the successor or acquiring company, and shall contain such additional provisions to protect the interests of the
Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 0. 

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company
shall promptly deliver to the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Share Exchange
Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture
to be delivered to each Holder promptly and in any event within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

(c) The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this
Section 14.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into shares of Common Stock, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Share
Exchange Event. 

  
 62 













 (d) The above provisions of this Section shall similarly apply to
successive Share Exchange Events. 
 Section 14.08 Certain Covenants. (a) The Company covenants that all shares of Common
Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and
interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c) The Company further
covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated
quotation system, any Common Stock issuable upon conversion of the Notes. 
 Section 14.09 Responsibility of Trustee. The
Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any
increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the
same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered
upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. 
 Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion
or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to
determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders
upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation)
as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officer’s Certificate (which the Company shall be obligated to deliver to the Trustee prior to the execution of any such
supplemental indenture) with respect thereto. The Trustee and the Conversion Agent may conclusively rely upon any notice with respect to the commencement or termination of such conversion rights. 

Section 14.10 Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to
Section 14.04 or Section 14.11; 
 (b) Share Exchange Event; or 

  
 63 













 (c) voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
 then, in each case (unless notice of such event is otherwise required pursuant to another
provision of this Indenture) and to the extent applicable, the Company shall cause to be delivered to the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, a notice stating (i) the date on which a
record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the
Company or one of its Subsidiaries, or (ii) the date on which such dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Share Exchange Event, dissolution, liquidation or winding-up. 

Section 14.11 Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes, each
share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, under such stockholder rights plan and the certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of
Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock
Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

Section 14.12 Exchange in Lieu of Conversion. When a Holder surrenders its Notes for conversion, the Company may, at its election
(an “Exchange Election”), direct the Conversion Agent to deliver, on or prior to the first (1st) Trading Day following the Conversion Date, such Notes to a financial institution
designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution must agree to timely pay and/or deliver, in exchange for such Notes, the shares of Common
Stock (plus any cash in lieu of fractional shares) plus the Interest Make-Whole Amount due upon conversion as described in Section 14.02. If the Company makes an Exchange Election, the Company shall, by the close of business on the first (1st) Trading Day following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent and the Holder surrendering its Notes for conversion that it has made the Exchange Election,
and the Company shall promptly notify the designated financial institution of the Physical Settlement Method with respect to such conversion and the relevant deadline for payment and/or delivery of shares of Common Stock, any cash in lieu of
fractional shares and the Interest Make-Whole Amount due upon conversion. 
 Any Notes exchanged by the designated financial institution
shall remain outstanding. If the designated financial institution agrees to accept any Notes for exchange but does not timely pay and/or deliver the required shares of Common Stock, any cash in lieu of fractional shares and the any cash and/or
Common Stock in respect of the Interest Make-Whole Amount due upon conversion, or if such designated financial institution does not accept the Notes for exchange, the Company shall notify in writing the Trustee, the Conversion Agent and the Holder
surrendering its Notes for conversion, and pay and/or deliver the required shares of Common Stock, together with cash in lieu of any fractional shares, plus the Interest Make-Whole Amount due upon conversion to the converting Holder at the time and
in the manner required under this Indenture as if the Company had not made an Exchange Election. 

  
 64 













 The Company’s designation of a financial institution to which the Notes may be
submitted for exchange does not require that financial institution to accept any Notes (unless the financial institution has separately made an agreement with the Company). The Company may, but shall not be obligated to, enter into a separate
agreement with any designated financial institution that would compensate it for any such transaction. 
 Section 14.13 Limits Upon
Issuance of Shares of Common Stock Upon Conversion. The Company shall not effect the conversion of any of the Notes held by a Holder, and such Holder shall not have the right to convert any of the Notes held by such Holder pursuant to the terms
and conditions of this Indenture and any such conversion shall be null and void and treated as if never made, to the extent that after giving effect to such conversion, such Holder together with the other Attribution Parties collectively would
beneficially own in excess of 9.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the aggregate number of shares of
Common Stock beneficially owned by such Holder and the other Attribution Parties shall include the number of shares of Common Stock held by such Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon
conversion of the Notes with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted Notes beneficially owned by such
Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any convertible notes, convertible preferred stock
or warrants, including the Notes) beneficially owned by such Holder or any other Attribution Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 14.13. For purposes of this
Section 14.13, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. For purposes of determining the number of outstanding shares of Common Stock a Holder may acquire upon the conversion of such
Notes without exceeding the Maximum Percentage, such Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Annual Report on Form 10-K,
Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission, as the case may be, (y) a more recent public announcement by
the Company or (z) any other written notice by the Company or the Transfer Agent, if any, setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). If the Company receives a
Conversion Notice from a Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify such Holder in writing of the number of shares of Common Stock then
outstanding and, to the extent that such Conversion Notice would otherwise cause such Holder’s beneficial ownership, as determined pursuant to this Section 14.13, to exceed the Maximum Percentage, such Holder must notify the Company of a
reduced number of shares of Common Stock to be delivered pursuant to such Conversion Notice. For any reason at any time, upon the written or oral request of any Holder, the Company shall within one (1) Business Day confirm orally and in writing
or by electronic mail to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company, including such Notes, by such Holder and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance of shares of Common Stock to a Holder upon conversion of such
Notes results in such Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the
Exchange Act), the number of shares so issued by which such Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and
shall be cancelled ab initio, and such Holder shall not have the power to vote or to transfer the Excess Shares. Upon delivery of a written notice to the Company, any Holder may from time to time increase (with such increase not


  
 65 













 
effective until the sixty-first (61st) day after delivery of such notice) or decrease the Maximum Percentage of such Holder to any other percentage not in excess of 9.99% as specified in such
notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to such
Holder and the other Attribution Parties and not to any other Holder that is not an Attribution Party of such Holder. For purposes of clarity, the shares of Common Stock issuable to a Holder pursuant to the terms of this Indenture in excess of the
Maximum Percentage shall not be deemed to be beneficially owned by such Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. No prior inability to
convert such Notes pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of convertibility. The provisions of this paragraph shall be construed and
implemented in a manner otherwise than in strict conformity with the terms of this Section 14.13 to the extent necessary to correct this paragraph (or any portion of this paragraph) which may be defective or inconsistent with the intended
beneficial ownership limitation contained in this Section 14.13 or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to
a successor holder of such Notes. Neither the Trustee nor the Conversion Agent shall have any responsibility to determine the Maximum Percentage or whether the issuance of any shares results in a Holder or Attribution Party having Excess Shares or
otherwise determine or monitor compliance with the terms of this Section 14.13. Notwithstanding anything to contrary herein, if in connection with any Mandatory Conversion of a Holder’s Notes there would be Excess Shares or unconverted
Notes with respect to such Holder, all such Holder’s Notes (including any unconverted Notes) shall nevertheless be deemed to have been converted, discharged, satisfied and repaid in full on the applicable Conversion Date and thereafter shall
not accrue any interest, provided that, upon request by such Holder, such Holder shall be entitled to receive a number of shares of Common Stock equal to such Excess Shares subject to the foregoing provisions of this Section 14.13. 

Section 14.14 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes or Mandatory Conversion. 
 (a) If (i) the Effective Date of a Make-Whole Fundamental Change occurs prior to the
Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or (ii) the Company delivers a Mandatory Conversion Notice in connection with such Make-Whole Fundamental Change as provided under
Section 14.03, as the case may be, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional
Shares”), to the extent and as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change (i) if the relevant Conversion Date occurs during the
period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that
would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the thirty-fifth (35th) Trading Day immediately following the Effective Date of such
Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”), or (ii) if it is a Mandatory Conversion. 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or Mandatory Conversion in connection with a
Make-Whole Fundamental Change, the Company shall satisfy the related Conversion Obligation by Physical Settlement in accordance with Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental
Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such
Make-Whole Fundamental Change, the 

  
 66 













 
Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to
the Conversion Rate (including any increase to reflect the Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the second (2nd) Business Day following the Conversion Date. The Company shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole
Fundamental Change no later than five (5) Business Days after such Effective Date. 
 (c) The number of Additional Shares, if any, by
which the Conversion Rate shall be increased for conversions in connection with a Make-Whole Fundamental Change or Mandatory Conversion shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change
occurs or becomes effective or the date the Company delivers the Mandatory Conversion Notice, as the case may be (in each case, the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per
share of the Common Stock in the Make-Whole Fundamental Change or determined with respect to the Mandatory Conversion Notice, as the case may be. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole
Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock
over the five (5) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the applicable Effective Date. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith
determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Record Date, Effective Date (as such term is used in Section 14.04) or Expiration
Date of the event occurs during such five (5) consecutive Trading Day period. If a Mandatory Conversion would also be deemed to be in connection with a Make-Whole Fundamental Change, a Holder of any such Notes to be converted will be entitled
to a single increase to the Conversion Rate with respect to the first to occur of the Effective Date of the Mandatory Conversion Notice or the Make-Whole Fundamental Change, as applicable, and the later event shall be deemed not to have occurred for
purposes of this Section 14.14. 
 (d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any
date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner
and at the same time as the Conversion Rate as set forth in Section 14.04. 
 (e) The following table sets forth the number of
Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.14 for each Stock Price and Effective Date set forth below:

 The exact Stock Price and Effective Date may not be set forth in the table above, in which
case: 
 (i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective
Dates in the table, the number of Additional Shares by which the conversion rate shall be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the
earlier and later Effective Dates, as applicable, based on a three hundred sixty-five (365) day year; 
 (ii) if the
Stock Price is greater than $50.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (e) above), no Additional Shares shall be added to the
Conversion Rate; and 
 (iii) if the Stock Price is less than $10.00 per share (subject to adjustment in the same manner as
the Stock Prices set forth in the column headings of the table above pursuant to subsection (e) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 100.0005 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 
 Nothing in this Section 14.14 shall prevent an
adjustment to the Conversion Rate that would otherwise be required pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change. 

Notwithstanding the foregoing, if in connection with any conversion of a Note (i) the Conversion Rate is eligible for adjustment in
accordance with this Section 14.14 and (ii) the Holder is entitled to receive the Interest Make-Whole Amount with respect to such Note, then one, but not both, of (A) the Conversion Rate adjustment in accordance with this
Section 14.14 and (B) the payment by the Company of the Interest Make-Whole Amount, shall apply, in each case according to which of (A) or (B) would result in more consideration being paid and/or delivered to the Holder in respect of
such conversion. 
 ARTICLE 15 

REPURCHASE OF NOTES AT OPTION OF HOLDERS 

Section 15.01 [Intentionally Omitted]. 

Section 15.02 Repurchase at Option of Holders Upon a Fundamental Change. 

(a) If a Fundamental Change occurs at any time prior to the Maturity Date, each Holder shall have the right, at such Holder’s option, to
require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof properly surrendered and not validly withdrawn pursuant to Section 15.03 that is equal to $1,000 or an integral multiple
of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty (20) Business Days or more than thirty-five (35) Business Days following the date of the Fundamental
Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, plus any remaining amounts that would be owed to, but excluding, the Maturity Date (the “Fundamental Change
Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full
amount of accrued and unpaid interest (to, but excluding, such Interest Payment Date) to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be
repurchased pursuant to this Article 0. The Fundamental Change Repurchase Date shall be subject to postponement in order to allow the Company to comply with applicable law. 

  
 68 













 (b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the
Holder thereof, upon: 
 (i) delivery to the paying agent by a Holder of a duly completed notice (the “Fundamental
Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Applicable Procedures for surrendering interests in Global
Notes, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the paying agent at any time after delivery of the Fundamental
Change Repurchase Notice (together with all necessary endorsements for transfer) at the office of the paying agent, or book- entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each
case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change Repurchase
Notice in respect of any Notes to be repurchased shall state: 
 (iii) in the case of Physical Notes, the certificate numbers
of the Notes to be delivered for repurchase; 
 (iv) the portion of the principal amount of Notes to be repurchased, which
must be in minimum denominations of $1,000 or an integral multiple thereof; and 
 (v) that the Notes are to be repurchased
by the Company pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global
Notes, the Fundamental Change Repurchase Notice must comply with the Applicable Procedures. 
 Notwithstanding anything herein to the
contrary, any Holder delivering to the paying agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior
to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the paying agent in accordance with Section 15.03. 

The paying agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of
withdrawal thereof. 
 (c) On or before the twentieth (20th) Business Day after the
occurrence of the effective date of a Fundamental Change, the Company shall provide to all Holders of Notes, the Trustee, the Conversion Agent (if other than the Trustee) and the paying agent (in the case of a paying agent other than the Trustee) a
written notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical
Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the Applicable Procedures of the Depositary. Each Fundamental Change Company Notice shall specify: 

  
 69 













 (i) the events causing the Fundamental Change; 

(ii) the effective date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

(vi) the name and address of the paying agent and the Conversion Agent, if applicable; 

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate; 

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and 

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02. Simultaneously with providing such notice, the Company will publish such information on its website or through such other public medium as the Company
may use at that time. 
 At the Company’s written request, given at least (5) five days prior to the date the Fundamental Change
Company Notice is to be sent, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared
by the Company. 
 (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders in
connection with a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in
the payment of the Fundamental Change Repurchase Price with respect to such Notes). The paying agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an
acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the Applicable Procedures shall
be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

(e) Notwithstanding anything to the contrary in this Indenture, the Company shall not be required to repurchase, or to make an offer to
repurchase, the Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Article 0
(including, without limitation, the requirement to comply with applicable securities laws), and such third party purchases all 

  
 70 













 
Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set
forth in this Article 0 (including the requirement to pay the Fundamental Change Repurchase Price on the later of the applicable Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the relevant Notes);
provided that the Company shall continue to be obligated to (x) deliver the applicable Fundamental Change Repurchase Notice to the Holders (which Fundamental Change Repurchase Notice shall state that such third party shall make such an
offer to purchase the Notes) and to simultaneously with such Fundamental Change Repurchase Notice publish a notice containing such information in a newspaper of general circulation in the City of New York or publish the information on the
Company’s website or through such other public medium as the Company may use at that time, (y) comply with applicable securities laws as set forth in this Indenture in connection with any such purchase and (z) pay the applicable
Fundamental Change Repurchase Price on the later of the applicable Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the relevant Notes in the event such third party fails to make such payment in such amount at
such time. 
 (f) For purposes of this Article 0, the paying agent may be any agent, depositary, tender agent, paying agent or other
agent appointed by the Company to accomplish the purposes set forth herein. 
 Section 15.03 Withdrawal of Fundamental Change
Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the office of the paying agent in accordance with this Section 15.03 at any
time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which must be $1,000
or an integral multiple thereof, 
 (ii) if Physical Notes have been issued, the certificate number of the Note in respect of
which such notice of withdrawal is being submitted, and 
 (iii) the principal amount, if any, of such Note that remains
subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 

provided, however, that if the Notes are Global Notes, the notice of withdrawal must comply with appropriate procedures of the Depositary. 

Section 15.04 Deposit of Fundamental Change Repurchase Price. 

(a) The Company will deposit with the Trustee (or other paying agent appointed by the Company), or if the Company is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 4.04 on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date (subject to extension in order to allow the Company to comply with applicable
law) an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other paying agent appointed by the Company),
payment for Notes surrendered for repurchase (and not validly withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change
Repurchase Date (provided the Holder has satisfied the conditions in Section 15.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other paying agent appointed by the


  
 71 













 
Company) by the Holder thereof in the manner required by Section 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note
Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the
Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 
 (b) If by 11:00 a.m. New York City time, on
the Fundamental Change Repurchase Date, the Trustee (or other paying agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date,
or, if extended in order to allow the Company to comply with applicable law, such later date, then, with respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn in accordance with the provisions of
this Indenture and the Applicable Procedures of the Depositary, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes on the Fundamental Change Repurchase Date or, if extended in order to allow the
Company to comply with applicable law, such later date (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or paying agent) and (iii) all other rights of the Holders of such Notes with
respect to the Notes will terminate on the Fundamental Change Repurchase Date or, if extended in order to allow the Company to comply with applicable law, such later date (other than (x) the right to receive the Fundamental Change Repurchase
Price and (y) to the extent not included in the Fundamental Change Repurchase Price, accrued and unpaid interest, if applicable). 
 (c)
Upon surrender of a Physical Note that is to be repurchased in part pursuant to Section 15.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Physical Note in an authorized denomination equal in
principal amount to the unrepurchased portion of the Physical Note surrendered. 
 Section 15.05 Repurchase of Notes. To the
extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to the Company’s obligations to purchase the Notes upon a Fundamental Change, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its obligations under such provisions of this Indenture by virtue of such conflict.

 Section 17.03 Addresses for Notices, Etc. Any notice or demand that by any
provision of this Indenture is required or permitted to be given or served by the Trustee or by the Holders on the Company shall be deemed to have been sufficiently given or made, for all purposes if given or served by being deposited postage

Section 17.10 Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf
and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06,
Section 2.07, Section 10.04 and Section 15.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this 

  
 74 













 
Indenture and those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be
authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the
Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section 7.08. 

Any corporation or other entity into which any authenticating agent may be merged or converted or with which it may be consolidated, or any
corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of any
authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section 17.10, without the execution or filing of any paper or any further act on

 Any authenticating agent may at
any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the

the Trustee), shall give written notice of such appointment to the Company and shall deliver notice of such appointment to all Holders.

Section 7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be applicable to any authenticating agent. 
 If
an authenticating agent is appointed pursuant to this Section 17.10, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

 Section 17.11 Execution in Counterparts. This Indenture may be executed in any number of counterparts, each of
which shall be an original, but such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile, PDF or other electronic transmission shall constitute
effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile, PDF or other electronic means shall be deemed
to be their original signatures for all purposes. Unless otherwise provided in this Indenture or in any Note, the words “execute,” “execution,” “signed” and “signature” and words of similar import used in or
related to any document to be signed in connection with this Indenture, any Note or any of the transactions

contemplated hereby (including amendments, waivers, consents and other modifications) shall be deemed to include electronic signatures and the keeping of records in electronic form, each of which
shall be of the same legal effect, validity or enforceability as a manually executed signature in ink or the use of a paper-based recordkeeping system, as applicable, to the fullest extent and as provided for in any applicable law, including the
Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other similar state laws based on the Uniform Electronic Transactions Act; provided that, notwithstanding
anything herein to the contrary, the Trustee is not under any obligation to agree to accept electronic signatures in any form or in any format unless expressly agreed to by the Trustee pursuant to procedures approved by the Trustee. 

Section 17.12 Severability. In the event any provision of this Indenture or in the Notes shall be invalid, illegal or
unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired. 

Section 17.13 Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

Section 17.14 Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of
its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, pandemics, epidemics, civil or military
disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services or the unavailability of the Federal Reserve Bank wire or telex write or
communication facility; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

Section 17.15 Calculations. The Company shall be responsible for making all calculations called for under the Notes. These
calculations include, but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, the Daily VWAPs, accrued interest payable on the Notes, any Additional Interest on the Notes, the Conversion Rate of the Notes, Buy-In Price, Maximum Percentage and Excess Shares. The Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of
Notes. The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations
without independent verification. The Trustee will forward the Company’s calculations to any registered Holder of Notes upon the written request of that Holder at the sole cost and expense of the Company. Neither the Trustee nor the Conversion
Agent will have any responsibility to make calculations under this Indenture, nor will either of them have any responsibility to monitor the Company’s stock or trading price, determine whether the conditions to convertibility of the Notes have
been met or determine whether the circumstances requiring changes to the Conversion Rate have occurred. 
 Section 17.16 USA PATRIOT
Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain,
verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may
request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act. 

  
 76 













 Section 17.17 Tax Withholding. The Company or the Trustee, as the case may be,
shall be entitled to make a deduction or withholding from any payment which it makes under this Indenture for or on account of any present or future taxes, duties or charges if and to the extent so required by any applicable law and any current or
future regulations or agreements thereunder or official interpretations thereof or any law implementing an intergovernmental approach thereto, in each case, that a Holder is subject to pursuant to the Indenture (“Applicable Tax
Law”), or by virtue of the relevant Holder failing to satisfy any certification or other requirements under Applicable Tax Law in respect of the Notes, in which event the Company or the Trustee, as the case may be, shall make such payment
after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted and shall have no obligation to gross up any payment hereunder or pay any additional amount as a result of such
withholding tax. 
 Notwithstanding any other provision of this Indenture, if the Company or other applicable withholding agent pays
withholding taxes or backup withholding on behalf of the Holder as a result of an adjustment or the nonoccurrence of an adjustment to the Conversion Rate, the Company or other applicable withholding agent may, at its option, withhold from or set off
such payments against payments of cash and shares of Common Stock on the Note (or any payments on the Common Stock) or sales proceeds received by or other funds or assets of the Holder.

 [FORM OF REVERSE OF NOTE] 

BigBear.ai Holdings, Inc. 
 6.00%
Convertible Senior Note due 2026 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 6.00% Convertible
Senior Notes due 2026 (the “Notes”), limited to the aggregate principal amount of $200,000,000 all issued or to be issued under and pursuant to an Indenture dated as of
[                ], 2021 (the “Indenture”), between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”),
to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes.
Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the
Indenture. 
 In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be
declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain
exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all payments and
deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such
payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

Notwithstanding any other provision of the Indenture or any provision of this Note, each Holder shall have the contractual right to receive
payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, this
Note, on or after the respective due dates expressed or provided for in this Note or in the Indenture, and the contractual right to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective
dates, shall not be amended without the consent of each Holder. 
 The Notes are issuable in registered form without coupons in minimum
denominations of $1,000 principal amount and integral multiples in excess thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be
exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that
may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

  
 A-6 













 The Notes are not subject to redemption through the operation of any sinking fund or
otherwise. 
 Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to
repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of
certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into
shares of Common Stock at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
