exchange, on the principal other market on which the Common Stock (or such other security) is then traded and (b) a Last Reported Sale Price for the Common Stock (or such other security) is available on such securities exchange or market;
provided that if the Common Stock (or such other security) is not so listed or traded, “Trading Day” means a

 ARTICLE 2

 THE SECURITIES 

Section 2.01 Form and Dating. (a) The Securities and the Trustee’s certificate of authentication shall be substantially
in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall
provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part
of this Indenture, and the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Any Security may be endorsed with or have incorporated in the text thereof
such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the Securities Custodian or the Depositary, 

  
 8 

 
or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the
Securities may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Securities are subject. 

(b) All of the Securities other than Affiliate Securities shall be issued initially in the form of one or more Global Securities, without
interest coupons, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company (“DTC”)
(such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as
hereinafter provided. 
 Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each
shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges, purchases or conversions of such Securities. Any adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities
represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and shall be made on the records of the Trustee and the Depositary. 

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to
any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 

No Affiliate Security may be transferred into a Global Security other than a Global Security representing solely Affiliate Securities other
than in connection with a transfer pursuant to Section 2.06(f). 
 (c) The Company shall execute and the Trustee
shall, in accordance with this Section 2.01(c), authenticate and deliver initially one or more Global Securities that (1) shall be registered in the name of the Depositary, (2) shall be delivered by the Trustee to
the Depositary or pursuant to the Depositary’s instructions and (3) shall bear a legend substantially to the following effect: 

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR
REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON
IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS
EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A 

  
 9 

 
PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE
FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE 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.” 
 Section 2.02 Execution and Authentication; Payments of
Interest and Defaulted Amounts.(a) The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof. An Officer shall sign the Securities for the
Company by manual or facsimile signature attested by the manual or facsimile signature of the Secretary or an Assistant Secretary of the Company. Typographic and other minor errors or defects in any such facsimile signature shall not affect the
validity or enforceability of any Security which has been authenticated and delivered by the Trustee. If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall
be valid nevertheless. A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated
under this Indenture. 
 (b) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating
agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.
An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 (c) The Trustee
shall authenticate and make available for delivery Securities (including the Affiliate Securities) for original issue in the aggregate principal amount of up to $215,000,000 (as increased by an amount equal to the aggregate principal amount of any
additional Securities purchased by the Initial Purchasers pursuant to the exercise of their option to purchase additional Securities as set forth in the Purchase Agreement) upon receipt of a written order or orders of the Company signed by at least
two Officers (a “Company Order”). The Securities initially issued will be comprised of (i) $207,000,000 aggregate principal amount of Restricted Securities and (ii) $8,000,000 aggregate principal amount of Affiliate Securities. The
Company Order shall specify the amount of Securities to be authenticated, shall provide that all such Restricted Securities will be represented by a Global Security and all such Affiliate Securities shall be Certificated Securities and the date on
which each original issue of Securities is to be authenticated. The Company at any time or from time to time may, without the consent of the Holders, reopen this Indenture and issue additional Securities under this Indenture having the same ranking,
interest rate, maturity and other terms as the Securities initially issued hereunder (other than differences in the issue price and interest accrued prior to the issue date of such additional Securities) in an unlimited aggregate principal amount,
and entitled to all of the benefits of this Indenture; provided that if any such additional Securities are not fungible with the Securities initially issued hereunder for U.S. federal income tax purposes or securities laws purposes, such
additional Securities shall have a separate CUSIP number. Such additional Securities shall, together with the Securities initially issued hereunder, constitute a single series of Securities under this Indenture, including without limitation in
determining the necessary Holders who may take the actions or consent to the taking of actions as specified in this Indenture, subject to Section 12.05. In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such additional Securities, the Trustee shall receive, and, shall be fully protected in relying upon: (a) an Officers’ Certificate delivered in accordance with
Section 2.01 and Section 12.04 and (b) an Opinion of Counsel which shall state (1) that the form and terms of such Securities have been established by or pursuant to a resolution of the
Board of Directors in accordance with Section 2.01 and Section 2.02 and in conformity with the provisions of this Indenture, (2) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to
bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles, and (3) that all conditions precedent under this Indenture in
respect of the execution and delivery by the Company of such Securities have been complied with. 

  
 10 

 (d) Accrued interest on the Securities shall be computed on the basis of a 360-day year composed of twelve 30-day months. The Person in whose name any Security (or its predecessor) is registered on the register of the Primary Registrar at the close
of business on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the Company maintained by the
Company for such purposes in the contiguous United States, which shall initially be the Corporate Trust Office. The Company shall pay interest (i) on any Certificated Securities by check mailed to the address of the registered Holder of such
Security; provided, however, that the Company will pay interest to any Holder of more than $2,000,000 aggregate principal amount of Certificated Securities by wire transfer in immediately available funds to an account within the United
States designated by such Holder in a written application delivered by such Holder to the Trustee and the Paying Agent not later than the Regular Record Date for the relevant Interest Payment Date, which application will remain in effect until such
Holder notifies the Trustee and Paying Agent, in writing, to the contrary or (ii) on any Global Security by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

(e) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date by virtue of its having been such
Holder but shall accrue interest per annum at the rate borne by the Securities, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date to, but excluding, the date on which such Defaulted Amounts
shall have been paid by the Company, at its election in each case, as provided in subsection (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Securities (or their
respective predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of the Defaulted Amounts proposed to be paid on each Security and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date),
and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to
the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of
such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall
promptly notify the Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each
Holder, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose
names the Securities (or their respective predecessor Securities) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following subsection (ii) of this
Section 2.02(e). 
 (ii) The Company may make payment of any Defaulted Amounts in any other lawful
manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Securities may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation
system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

 

  
 11 

 Section 2.03 Registrar, Paying Agent and Conversion Agent. The Company shall maintain
one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented for payment or repurchase (each,
a “Paying Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a “Conversion Agent”) and one or more offices or agencies where notices and demands to or upon the Company
in respect of the Securities and this Indenture may be served, such offices and agencies to be maintained in the contiguous United States. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency
where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”) shall keep a register
of the Securities and of their registration of transfer and exchange. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. 

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall give prompt written notice to the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent,
Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent or Bid
Solicitation Agent (except for the purposes of Section 5.01 and Article 9). 
 The Company hereby initially
designates the Trustee as Paying Agent, Primary Registrar, Securities Custodian, Bid Solicitation Agent and Conversion Agent and each of the Corporate Trust Office of the Trustee and the office or agency of the Trustee in the Borough of Manhattan,
The City of New York, as an office or agency of the Company for each of the aforesaid purposes. 
 Section 2.04 Paying Agent to Hold
Money in Trust. Prior to 11:00 a.m., New York City time, on each due date of the principal of or interest on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal or interest so becoming due. A
Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities, and shall notify the Trustee of any default by the Company (or any other
obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each due date of the principal of or interest on any Securities, segregate
the money and hold it as a separate trust fund for the benefit of the Holders. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any default, upon
written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. 

Section 2.05 Holder. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of the Holders. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee at least seven Business Days before each semiannual interest payment date, and at such other times as the Trustee
may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders. 

Section 2.06 Transfer and Exchange; Transfer Restrictions. (a) Subject to compliance with any applicable additional
requirements contained in Section 2.12, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized
denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an
assignment form in form satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or
exchange at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange
or registration of transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, and provided, that
this sentence shall not apply to any exchange pursuant to Section 2.07, Section 2.10, Section 3.06, Section 4.02(d) or
Section 10.05. 

  
 12 

 Neither the Company, any Registrar nor the Trustee shall be required to exchange or register
a transfer of any Securities or portions thereof in respect of which a Repurchase Exercise Notice pursuant to Section 3.02(c) has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase
of a Security in part, the portion thereof not to be purchased). 
 All Securities issued upon any registration of transfer or exchange of
Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 

(b) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such information as the Trustee may
reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
 (c) Each
Holder agrees to indemnify the Company, each Registrar and the Trustee against any liability that may result from the registration of transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture
and/or applicable United States federal or state securities law. 
 (d) Every Security that bears or is required under this
Section 2.06(d) to bear the legend set forth in this Section 2.06(d) (together with any Common Stock issued upon conversion of the Securities that is required to bear the legend set forth in
Section 2.06(e), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.06(d) (including the legend set forth
below), 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 2.06(d) and Section 2.06(e), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any
Restricted Security. 
 Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date
that is one year after the last date of original issuance of the Securities, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be
required by applicable law, any certificate evidencing such Security (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in
Section 2.06(e), if applicable) shall bear a legend in substantially the following form (unless (i) such Securities have 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 sold 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 in writing, with notice thereof to the Trustee, or (ii) such Security is an Affiliate Security, in which case it shall bear the Affiliate Restricted Security Legend): 

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. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

 (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER”
(WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 

  
 13 

 (2) AGREES FOR THE BENEFIT OF GOGO 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 LAST ORIGINAL 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 OF THE COMPANY, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), 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)(D) 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 transfer of any Security prior to the Resale Restriction Termination Date will be registered by the Security Registrar unless the
applicable box on the Form of Assignment and Transfer has been checked. 
 Any Security (or security issued in exchange or substitution
therefor) that does not constitute an Affiliate Security as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Security for exchange to the Security Registrar in accordance with the
provisions of this Section 2.06, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this
Section 2.06(d) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Securities Custodian in writing to so surrender any Global Security as to which such restrictions on
transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Securities Custodian shall so surrender such Global Security for exchange; and any new Global Security so exchanged therefor shall not bear the
restrictive legend specified in this Section 2.06(d) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction Termination Date and
promptly after a registration statement, if any, with respect to the Securities or any Common Stock issued upon conversion of the Securities has been declared effective under the Securities Act. The Affiliate Securities Legend shall be removed from
Affiliate Securities (and the restrictions on transfer therein contained shall cease to apply) only in connection with a transfer pursuant to Section 2.06(f). 

(e) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of such Security
(other than an Affiliate Security) shall bear a legend in substantially the following form (unless the Security or 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 Securities that have 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):

 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. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 

(1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE
MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 

(2) AGREES FOR THE BENEFIT OF GOGO 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 LAST ORIGINAL ISSUE DATE OF THE SERIES OF 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 OF THE COMPANY, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

(D) 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)(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 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 as to which such restrictions on transfer shall have expired in accordance with their terms 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 2.06(e). 
 Any Security or Common
Stock issued upon the conversion or exchange of a Security that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by 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 Security or Common Stock, as
the case may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Company shall cause any Security that is repurchased or owned by it or any of its Subsidiaries to be surrendered to the
Trustee for cancellation in accordance with Section 2.11. 

  
 15 

 The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of
interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the
same to determine substantial compliance as to form with the express requirements hereof. 
 Neither the Trustee nor any Agent shall have
any responsibility for any actions taken or not taken by the Depositary. The Trustee shall have no responsibility or obligation to any beneficial owner of an interest in a Global Security, Agent Members or any other Persons with respect to the
accuracy of the records of DTC or its nominee or of Agent Members, with respect to any ownership interest in the Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than DTC) of any notice or the
payment of any amount or delivery of any Securities (or other security or property) under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the
Securities shall be given or made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through DTC,
subject to the applicable rules and procedures of DTC. The Trustee may rely and shall be fully protected in relying upon information furnished by DTC with respect to its Agent Members and any beneficial owners. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or beneficial owners in any Security) other than to require delivery of such certificates and
other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

 (f) Affiliate Securities. (i) Each Affiliate Security will be subject to the restrictions on transfer set forth in
this Indenture (including in the Affiliate Securities Legend) and, to the extent such Affiliate Securities bear a CUSIP number, will bear a restricted CUSIP number for the Securities (which CUSIP number will be distinct from the CUSIP number for any
other Securities) unless such restrictions on transfer are eliminated or otherwise waived by a written consent of the Company, and each Holder of an Affiliate Security, by such Holder’s acceptance of such Affiliate Security, will be deemed to
be bound by the applicable restrictions on transfer applicable to such Affiliate Security. 
 (ii) Any Affiliate Security
will bear the Affiliate Securities Legend unless: 
 (1) Such Security was transferred (A) to the Company or a
Subsidiary of the Company or (B) to a non-Affiliate of the Company pursuant to a registration statement that was effective under the Securities Act at the time of such transfer; 

(2) Such Security was transferred to a non-Affiliate of the Company pursuant to Rule
144 under the Securities Act; or 
 (3) The date on which the Holder of such Security (A) has a “holding
period” (determined pursuant to Rule 144(d) under the Securities Act) of at least one year and (B) is not an Affiliate of the Company (and has not been an Affiliate of the Company during the three months immediately preceding). 

(iii) In addition, no transfer of any Affiliate Securities will be registered by the Registrar unless the transferring Holder
delivers a notice substantially in the form of the Assignment Form attached to such Security, with the appropriate box checked, to the Trustee and such transfer complies with the transfer restrictions set forth in the Affiliate Securities Legend.

  
 16 

 (iv) No Securities bearing, or required to bear, the Affiliate Securities
Legend (or any interest therein) may be exchanged for, or transferred with the Holder taking delivery in the form of, Securities bearing, or required to bear, the Restricted Securities Legend (or any interest therein), other than following a
transfer of such Affiliate Securities to a non-Affiliate of the Company (which shall not include, for the avoidance of doubt, a Person that was an Affiliate of the Company during the three months immediately
preceding) pursuant to (A) Rule 144 under the Securities Act or (B) a registration statement that was effective under the Securities Act at the time of such transfer. 

(v) Any shares of Common Stock issued upon conversion of an Affiliate Security will be issued in book-entry form and will bear
the Affiliate Restricted Stock Legend at any time the Company reasonably determines that, to comply with law, such share of Common Stock must bear the Affiliate Restricted Stock Legend. 

Section 2.07 Replacement Securities. If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of
them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute, and upon its written request the Trustee shall authenticate and
deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be repurchased
by the Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Security, pay or repurchase such Security, as the case may be. 

Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum
sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 

Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security
shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of (but shall be
subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 

The provisions of this Section 2.07 are (to the extent lawful) exclusive and shall preclude (to the extent lawful)
all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 

Section 2.08 Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee, except
for those canceled by it, those converted pursuant to Article 4, those delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding. 

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Security is held by a protected purchaser. 
 If a Paying Agent (other than the Company or an Affiliate
of the Company) holds on the Maturity Date money sufficient to pay the principal of and accrued interest on Securities (or portions thereof) payable on that date, then on and after such Maturity Date such Securities (or portions thereof, as the case
may be) shall cease to be outstanding and interest on them shall cease to accrue. 

  
 17 

 Subject to the restrictions contained in Section 2.09, a Security
does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
 Section 2.09 Treasury
Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate
of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities that a Responsible Officer of
the Trustee actually knows are so owned shall be so disregarded. Securities so owned that have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with
respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. 

Section 2.10 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and execute, and,
upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of Certificated Securities but may have variations that the Company considers appropriate for
temporary Securities and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order, shall authenticate and deliver definitive Securities in exchange for
temporary Securities. Holders of temporary Securities shall be entitled to all the benefits of and subject to the same limitations under this Indenture as Certificated Securities authenticated and delivered hereunder. 

Section 2.11 Cancellation; Repurchase. The Company shall cause all Securities surrendered for the purpose of payment, purchase
upon a Fundamental Change in accordance with Article 3, repurchase, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or
Affiliates), to be delivered to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for registration of transfer, exchange, payment or
conversion. The Company shall instruct the Trustee in writing to cancel all Securities surrendered for the purpose of payment, repurchase, registration of transfer, exchange, conversion or cancellation, and the Trustee and no one else shall promptly
cancel, in accordance with its standard procedures and upon the Company’s written instruction, all Securities so surrendered and shall dispose of canceled Securities (subject to the record retention requirements of the Exchange Act), in
accordance with its standard procedures, and no Securities shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Company may not hold or resell such Securities or issue new
Securities to replace Securities that it has purchased or otherwise acquired or that have been delivered to the Trustee for cancellation. 

The Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Securities are surrendered to the
Company), repurchase Securities in the open market, by tender offer or exchange offer, by private agreement through counterparties or otherwise, whether by the Company or its Subsidiaries, including by cash-settled swaps or other derivatives and, in
each case, at any price. The Company shall cause any Securities so purchased (other than Securities repurchased pursuant to cash-settled swaps or other derivatives that are not physically settled) to be surrendered to the Trustee for cancellation in
accordance with this Section 2.11, and they shall no longer be considered outstanding under this Indenture upon their repurchase. Any Securities held by the Company or one of its Subsidiaries shall be disregarded for voting
purposes in connection with any notice, waiver, consent or direction requiring the vote or concurrence of Holders. 
 Section 2.12
Additional Transfer and Exchange Requirements. (a) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other
Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be
effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in
part, shall be made only in accordance with this Section 2.12. 

  
 18 

 (b) The provisions of subsections (i), (ii), (iii) and
(iv) below shall apply only to Global Securities: 
 (i) Notwithstanding any other provisions of this Indenture
or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged
for Certificated Securities registered in the names of any Person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or
the Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days or (B) an Event of Default has occurred and is continuing and a
beneficial owner requests that its Securities be exchanged for Certificated Securities. Any Global Security exchanged pursuant to clause (A) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to
clause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such
Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 

(ii) Securities issued in exchange for a Global Security or any portion thereof shall be issued in fully-registered book-entry
form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall
designate and shall bear any applicable legend provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either
such Global Security shall be so surrendered for exchange or, if the Trustee is acting as Securities Custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal
to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon
the order of the Depositary or an authorized representative thereof; provided, however, that any Global Security surrendered for exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the
proviso to the first paragraph of Section 2.06(a). 
 (iii) Subject to the provisions of
subsection (v) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take
under this Indenture or the Securities. 
 (iv) In the event of the occurrence of any of the events specified in
subsection (i) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 

(v) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an
Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Security. 

  
 19 

 (c) In the event that Certificated Securities are issued in exchange for beneficial
interests in Global Securities and, thereafter, the events or conditions specified in Section 2.12(b)(i) that required such exchange shall cease to exist, the Company shall deliver notice to the Trustee and to the Holders
stating that Holders may exchange Certificated Securities for interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such
notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request: 
 (i) to
register the transfer of such Certificated Securities to a Person who will take delivery thereof in the form of a beneficial interest in a Global Security; or 

(ii) to exchange such Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which
beneficial interests will be owned by the Holder transferring such Certificated Securities, 
 the Registrar shall register the transfer or make the
exchange as requested by canceling such Certificated Securities and causing, or directing the Securities Custodian to cause, the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security
is then outstanding, the Company shall issue and the Trustee, upon receipt of a Company Order, shall authenticate and deliver a new Global Security; provided, however, that the Certificated Securities presented or surrendered for
registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.06(a); and provided further that if a
Holder requests a transfer of a Certificated Security that is an Affiliate Security, such Holder will deliver any documentation that the Company, the Trustee or the Registrar may require to ensure that such transfer complies with
Section 2.06(f) and any applicable securities laws. Notwithstanding the foregoing, no Affiliate Security that is a Certificated Security may be transferred into a Global Security other than a Global Security representing
solely Affiliate Securities other than in connection with a transfer pursuant to Section 2.06(f). 
 The Trustee
shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any
transfers between or among Agent Members or beneficial owners in any Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the
terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

Section 2.13 CUSIP Numbers. The Company in issuing the Securities may use one or more “CUSIP” numbers (if then generally
in use), and, if so, the Trustee shall use “CUSIP” numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice or related action by the Company contemplated thereby shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

ARTICLE 3 
 REPURCHASE
UPON A FUNDAMENTAL CHANGE 
 Section 3.01 No Sinking Fund. No sinking fund is provided for the Securities. 

Section 3.02 Repurchase at Option of the Holder Upon a Fundamental Change. (a) Subject to the satisfaction of the
requirements of this Article 3, if a Fundamental Change occurs at any time prior to May 15, 2022, each Holder shall have the right, at its option, to require the Company to repurchase for cash all of their Securities, or any portion of
the principal thereof that is equal to $1,000 or an integral multiple of $1,000 at a repurchase price (the “Fundamental Change Repurchase Price”) equal to 100% of the principal amount of the Securities to be repurchased plus accrued
and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date (unless such Fundamental Change Repurchase Date falls after a Regular Record Date and on or prior to the 

  
 20 

 
corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued and unpaid interest payable on such Interest Payment Date to the Holder of record at the close
of business on such Regular Record Date and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of the Securities to be repurchased). The Company shall provide to the Holders of the Securities, the Trustee, the
Paying Agent and the Conversion Agent (if other than the Trustee) a notice (i) at least 90 Scheduled Trading Days prior to the anticipated effective date of a Fundamental Change or (ii) if the Company does not have knowledge of a
Fundamental Change at least 90 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the earlier of (x) the date upon which the Company receives, or otherwise becomes aware, of the
anticipated effective date of such Fundamental Change and (y) the actual effective date of such Fundamental Change. 
 (b) In addition
to the notice required pursuant to Section 3.02(a), on or before the 10th Business Day after the date on which a Fundamental Change becomes effective, the Company shall provide to all Holders of the Securities, the Trustee
and the Conversion Agent (if other than the Trustee) a notice of the occurrence of the Fundamental Change and of the resulting repurchase right (the “Fundamental Change Repurchase Right Notice”). The Fundamental Change Repurchase
Right Notice shall state: 
 (i) the event or events giving rise to the Fundamental Change; 

(ii) if the Fundamental Change also constitutes a Make-Whole Fundamental Change; 

(iii) the Conversion Rate and any adjustments to the Conversion Rate; 

(iv) the effective date of the Fundamental Change; 

(v) the last date on which a Holder may exercise the repurchase right; 

(vi) the Fundamental Change Repurchase Price; 

(vii) the Fundamental Change Repurchase Date; 

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

(ix) that the Securities with respect to which a Repurchase Exercise Notice has been given by the Holder may be converted only
if the Holder withdraws the Repurchase Exercise Notice as described in Section 3.02(d); and 
 (x)
the procedures that Holders must follow to require the Company to repurchase their Securities. 
 Simultaneously with providing the
Fundamental Change Repurchase Right Notice, the Company shall issue a press release and publish the information through a public medium customary for such press releases. 

(c) To exercise the repurchase right in connection with a Fundamental Change, a Holder must deliver, prior to the close of business, on the
Business Day immediately preceding the Fundamental Change Repurchase Date, the Securities to be purchased to the Paying Agent, duly endorsed for transfer, or effect book-entry transfer of the Securities to the Paying Agent, together with a written
notice exercising its right to require the Company to repurchase its Securities or a portion thereof (a “Repurchase Exercise Notice”), substantially in the form included in Exhibit A hereto, duly completed, to the Paying
Agent. The Repurchase Exercise Notice must state: 
 (i) if the Securities are Certificated Securities, the certificate
numbers of the Securities to be delivered for repurchase; 

  
 21 

 (ii) the portion of the principal amount of the Securities to be
repurchased, which must be equal to $1,000 or an integral multiple thereof; and 
 (iii) that the Securities are to be
repurchased by the Company as of the Fundamental Change Repurchase Date pursuant to the applicable provisions of the Securities and this Indenture. 

If the Securities are Global Securities, the Repurchase Exercise Notice must comply with the Applicable Procedures. 

A Holder may withdraw any Repurchase Exercise Notice (in whole or in part) by a written notice of withdrawal delivered to the Paying Agent
prior to the close of business on the Business Day prior to the Fundamental Change Repurchase Date. The notice of withdrawal must state: 

(i) the principal amount of the Securities for which the Repurchase Exercise Notice has been withdrawn; 

(ii) if Certificated Securities have been issued, the certificate numbers of the withdrawn Securities; and 

(iii) the principal amount, if any, that remains subject to the Repurchase Exercise Notice. 

If the Securities are Global Securities, the withdrawal notice must comply with the Applicable Procedures. 

(d) The Company must repurchase on a date (the “Fundamental Change Repurchase Date”) chosen by the Company that is no less
than 20 and no more than 35 Business Days after the date of the Fundamental Change Repurchase Right Notice with respect to the occurrence of the relevant Fundamental Change. To receive payment of the Fundamental Change Repurchase Price, a Holder
must either effect book-entry transfer or deliver the Securities, together with necessary endorsements, to the office of the Paying Agent after delivery of the Repurchase Exercise Notice. Holders shall receive payment of the Fundamental Change
Repurchase Price on the later of (i) the Fundamental Change Repurchase Date and (ii) the time of book-entry transfer or the delivery of the Securities. If the Paying Agent holds money deposited by the Company sufficient to pay the
Fundamental Change Repurchase Price of the Securities on the Fundamental Change Repurchase Date, then with respect to the Securities that have been properly surrendered for repurchase and have not been validly withdrawn: 

(i) the Securities will cease to be outstanding and interest, if any, will cease to accrue (whether or not book-entry transfer
of the Securities is made or whether or not the Securities are delivered to the Paying Agent); and 
 (ii) all other rights
of the Holder of such Securities will terminate (other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of the Securities). 

Section 3.03 Compliance With Securities Laws Upon Purchase of Securities. (a) In connection with any offer to purchase the
Securities under Section 3.02, the Company shall comply with all tender offer rules applicable to the Company under the Exchange Act. The Company shall (a) comply with the provisions of Rule 13e-4, Rule 14e-l (or any successor to either such Rule) and any other tender offer rules, if applicable, under the Exchange Act, (b) file a Schedule TO (or any successor
or similar schedule, form or report), if required, under the Exchange Act and (c) otherwise comply with all federal and state securities laws in connection with such offer by the Company to purchase the Securities upon a Fundamental Change, so
as to permit the rights of the Holders and obligations of the Company under Section 3.02 to be exercised in the time and in the manner specified therein. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 3.03, the Company, shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this
Section 3.03 by virtue of such conflict. 

  
 22 

 Section 3.04 No Repurchase Upon Acceleration. No Securities may be repurchased
on any date at the option of Holders upon a Fundamental Change if the principal amount of the Securities 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 Securities). The Paying Agent will promptly return to the respective Holders thereof any Certificated Securities held by it following the
acceleration of the Securities (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 Securities), and any instructions for book-entry transfer of
the Securities in compliance with the procedures of the Depositary 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. 
 Section 3.05 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 3.02 exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change
Repurchase Date, the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company. 
 Section 3.06
Partial Repurchase. Upon surrender of a Security that is to be repurchased in part pursuant to Section 3.02, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an
authorized denomination equal in principal amount to the unrepurchased portion of the Security surrendered. 
 ARTICLE 4 

CONVERSION 

Section 4.01 Conversion Rights. (a) Subject to and upon compliance with the provisions of this
Article 4, each Holder of a Security 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
Security (i) subject to satisfaction of one or more of the conditions described in subsections (b) through (e) of this Section 4.01, at any time prior to the close of business on the Business Day
immediately preceding January 15, 2022 under the circumstances and during the periods set forth in subsections (b) through (e) of this Section 4.01, and (ii) irrespective of the conditions set
forth in subsections (b) through (e) of this Section 4.01, on or after January 15, 2022 and prior to the close of business on the second Scheduled Trading Day immediately preceding May 15, 2022,
in each case at an initial conversion rate of 166.6667 shares of Common Stock (subject to adjustment as provided in Section 4.05, the “Conversion Rate”) per $1,000 principal amount of Securities (subject to
the settlement provisions of Section 4.02, the “Conversion Obligation”). 
 (b) Prior to the close
of business on the Business Day immediately preceding January 15, 2022, a Holder may surrender all or any portion of its Securities for conversion during any calendar quarter commencing after the calendar quarter ending on December 31,
2018 (and only during any such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the
immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. 
 (c) Prior
to the close of business on the Business Day immediately preceding January 15, 2022, a Holder of the Securities may surrender all or any portion of its Securities for conversion during the five Business Day period after any five consecutive
Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of the Securities, as determined following a request by a Holder of the Securities in accordance with the procedures described
below, for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of Common Stock and the Conversion Rate on each such Trading Day. The Bid Solicitation Agent (if other than the Company) shall
have no obligation to determine the Trading Price of the Securities unless the Company has requested such determination in writing; and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation
Agent, it shall have no obligation to determine the Trading Price) unless a Holder of the Securities requests in writing that the Company 

  
 23 

 
make such a determination and provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Securities would be less than 98% of the product of the Last
Reported Sale Price of Common Stock and the Conversion Rate. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine (and such Bid Solicitation Agent shall provide such determination to the
Company), or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of Securities beginning on the next Trading Day and on each successive Trading Day until the Trading Price
per $1,000 principal amount of Securities is greater than or equal to 98% of the product of the Last Reported Sale Price of Common Stock and the Conversion Rate. If the trading price condition has been met, the Company shall notify the Holders, the
Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the trading price condition has been met, the Trading Price per $1,000 principal amount of Securities is greater than or equal to 98% of the product of the Last
Reported Sale Price of Common Stock and the Conversion Rate for such date, the Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If (i) the Company is not acting as the Bid Solicitation Agent,
and the Company does not, when it is required to do so, instruct the Bid Solicitation Agent to obtain bids, or if the Company gives such instruction to the Bid Solicitation Agent and the Bid Solicitation Agent fails to make such determination; or
(ii) if the Company is acting as Bid Solicitation Agent and it fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Securities will be deemed to be less than 98% of the product of the Last
Reported Sale Price of Common Stock and the Conversion Rate for each Trading Day on which such failure occurs. 
 (d) If the Company elects
to: 
 (i) issue to all or substantially all holders of Common Stock any rights, options or warrants entitling them, for a
period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of 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 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(ii) distribute to all or substantially all holders of Common Stock, the Company’s assets, securities or rights to
purchase the Company’s securities, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of
announcement of such distribution, 
 then, in either case, the Company shall notify the Holders of the Securities (with a copy of such notice to the
Trustee and the Conversion Agent (if other than the Trustee)) at least 90 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders
may surrender all or any portion of their Securities for conversion at any time until the earlier of (x) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such
issuance or distribution and (y) the Company’s announcement that such issuance or distribution will not take place, even if the Securities are not otherwise convertible at such time. No Holder may convert any of its Securities pursuant to
the conditions set forth in this Section 4.01(d) if such Holder otherwise participates in such issuance or distribution, at the same time and upon the same terms as holders of Common Stock and as a result of holding the Securities, without
having to convert their Securities, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder. 

(e) If a transaction or event that (x) constitutes a Fundamental Change or (y) constitutes a Make-Whole Fundamental Change occurs,
regardless of whether a Holder of the Securities has the right to require the Company to repurchase the Securities pursuant to Section 3.02, or if the Company is a party to a consolidation, merger, binding share exchange,
or transfer or lease of all or substantially all of the Company’s assets, in each case pursuant to which Common Stock would be converted into cash, securities or other assets, then all or any portion of a Holder’s Securities may be
surrendered for conversion at any time from or after the date that is 90 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Company gives notice of such transaction) until 35
Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date; provided that the Securities will not become convertible by
reason of a consolidation, merger or other 

  
 24 

 
transaction effected with one of the Company’s direct or indirect wholly-owned Subsidiaries that is a corporation or limited liability company for the sole purpose of changing the
Company’s state of incorporation or organization to any other state within the United States or the District of Columbia so long as, for the avoidance of doubt, immediately after giving effect to such transaction, the Securities and the shares
of Common Stock, if any, issuable upon conversion thereof are, in each case, eligible to be sold by a Person that is not (and has not been for the immediately preceding three months) an affiliate of the issuer thereof without any volume or manner of
sale restrictions to the same extent as if such transaction had not occurred. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company
publicly announces such transaction but in no event less than 90 Scheduled Trading Days prior to the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of such transaction at least 90 Scheduled Trading
Days prior to the anticipated effective date of such transaction, then within one Business Day of the earlier of (x) the date upon which the Company receives notice, or otherwise becomes aware, of the anticipated effective date of such
transaction and (y) the actual effective date of such transaction. 
 Section 4.02 Settlement Upon Conversion; Conversion
Procedures. (a) Subject to this Section 4.02, Section 4.04 and Section 4.07, upon conversion of any Security, the Company shall pay or deliver, as the case may
be, to the converting Holder, in respect of each $1,000 principal amount of Securities being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common
Stock in accordance with subsection (i) of this Section 4.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any
fractional share of Common Stock in accordance with subsection (i) of this Section 4.02 (“Combination Settlement”), at its election, as set forth in this Section 4.02.

 (i) All conversions for which the relevant Conversion Date occurs on or after November 15, 2021 shall be settled
using the same Settlement Method. Except for conversions of Securities described in the preceding sentence, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have
any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates. If, in respect of any Conversion Date (or with respect to the period beginning on, and including, November 15, 2021 and ending on, and
including, the second Scheduled Trading Day immediately preceding May 15, 2022, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such
Conversion Date (or such period, as the case may be), the Company, through the Trustee (upon request of the Company), shall deliver such Settlement Notice to converting Holders no later than the close of business on the Trading Day immediately
following the relevant Conversion Date (or, in the case of any conversions of Securities for which the relevant Conversion Date occurs on or after November 15, 2021, no later than November 15, 2021). If the Company does not elect a
Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination
Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Securities shall be deemed to be $1,000. Such Settlement Notice shall be prepared by the Company and shall specify the relevant
Settlement Method and, in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company elects Combination Settlement but does not timely notify converting Holders of the
Specified Dollar Amount per $1,000 principal amount of Securities, such Specified Dollar Amount will be deemed to be $1,000. 

(ii) With respect to any conversion of Securities, the cash, shares of Common Stock or combination of cash and shares of Common
Stock in respect of such conversion (the “Settlement Amount”) shall be computed as follows: 
 (A) if the
Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Securities being converted a number of shares
of Common Stock equal to the Conversion Rate on the Conversion Date; 

  
 25 

 (B) if the Company elects to satisfy its Conversion Obligation in respect
of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Securities being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 80
consecutive Trading Days during the related Observation Period; and 
 (C) if the Company elects (or is deemed to have
elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement
Amount equal to the sum of the Daily Settlement Amounts for each of the 80 consecutive Trading Days during the related Observation Period. 

(iii) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the
Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share,
the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of fractional shares of Common
Stock. 
 (b) Subject to Section 4.02(e), before any Holder of a Security shall be entitled to convert a Security
as set forth above, such Holder shall (i) in the case of a Certificated Security (A) complete and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Conversion Notice attached to the Form of Security set
forth in Exhibit A hereto (a “Conversion Notice”) at the office of the Conversion Agent and state in writing therein the principal amount of Securities 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 by the Company or its agent upon settlement of the Conversion Obligation to be registered, (B) deliver such Security, duly endorsed to the Company or
in blank (and accompanied by appropriate endorsement and transfer documents), to the Conversion Agent and (C) 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 subsection (g) of this Section 4.02 and (ii) in the case of a Global Security, comply with the Depositary’s procedures for converting a beneficial interest in a Global Security and, 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 subsection (g) of this Section 4.02. The Trustee (and, if different, the Conversion Agent)
shall notify the Company of any conversion pursuant to this Article 4 on the Conversion Date for such conversion. No Conversion Notice with respect to any Securities 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 Securities and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 3.02(c). 

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

(c) A Security shall be deemed to have been converted immediately prior to the close of business on the Business Day (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above; provided that in the case of a Global Security, no Holder shall be deemed to have complied with the requirements set forth in
subsection (b) above on any Business Day that the Depositary is not open for business. The Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the second Business Day
immediately following the relevant Conversion Date, in the case of Physical Settlement (provided that, with respect to any Conversion Date occurring on or after May 1, 2022, the Company shall settle any such conversion on May 15,
2022), or on the second Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to
be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be
entitled in satisfaction of the Company’s Conversion Obligation. 

  
 26 

 (d) In case any Security 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 Security so surrendered a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Security, 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 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 Securities issued upon such conversion being different from the name of the Holder of the old Securities surrendered for such conversion. 

(e) If a Holder submits a Security for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on any
issuance of any shares of Common Stock upon the conversion, unless the tax is due because the Holder requests any shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Company or its stock
transfer 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 Company or its representative receives a sum sufficient to pay any tax that is due by
such Holder in accordance with the immediately preceding sentence. 
 (f) Upon the conversion of an interest in a Global Security, the
Trustee, or the Securities Custodian at the direction of the Trustee, shall make a notation on such Global Security as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of
Securities effected through any Conversion Agent other than the Trustee. 
 (g) Except as described below, the Company shall not make any
separate cash payment for accrued and unpaid interest, if any, upon conversion of Securities. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Security
and accrued and unpaid interest, if any, attributable to the period from, and including, the most recent Interest Payment Date to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the
Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Securities into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first
out of the cash paid upon such conversion. Notwithstanding the foregoing, if Securities are submitted for conversion after the close of business on a Regular Record Date and prior to the open of business on the immediately following Interest Payment
Date, Holders of such Securities as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Securities on such Interest Payment Date notwithstanding the conversion, and Securities surrendered
for conversion after the close of business on a Regular Record Date and prior 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 principal amount of
the Securities being converted; provided that no such payment need be made: 
 (i) for conversions after the close of
business on May 1, 2022, which is the Regular Record Date immediately preceding the Maturity Date; 
 (ii) if the
Company has specified a Fundamental Change Repurchase Date that is (a) after a Regular Record Date and (b) on or prior to the second Business Day immediately following the corresponding Interest Payment Date; or 

(iii) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such
Security. 
 As a result of the foregoing, the Company shall pay interest on the Maturity Date on all Securities converted after the Regular
Record Date preceding the Maturity Date, and Holders shall not be required to pay the Company equivalent interest amounts. 

  
 27 

 (h) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a shareholder of record as of the close of business on the relevant Conversion Date (in the case of Physical Settlement) or the last Trading Day of the relevant Observation Period (in the case of
Combination Settlement), as the case may be. Upon a conversion of Securities, such Person shall no longer be a Holder of such Securities surrendered for conversion. 

(i) The Company shall not issue any fractional share of Common Stock upon conversion of the Securities 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 (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation
Period (in the case of Combination Settlement). For each Security surrendered for conversion, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of shares that shall be issued upon conversion thereof
shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

(j) Each conversion shall be deemed to have been effected as to any Security surrendered for conversion on the Conversion Date;
provided, however, that the Person in whose name any shares of Common Stock shall be issuable upon such conversion shall become the holder of record of such shares as of the close of business on the Conversion Date (in the case of
Physical Settlement) or the close of business on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). 

Section 4.03 Company to Provide Stock. The Company shall, prior to issuance of any Securities hereunder, and from time to time as
may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock (assuming that at the time of computation of
such number of shares, all such Securities would be converted by a single Holder and that Physical Settlement is applicable). 
 All shares
of Common Stock delivered upon conversion of the Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. 

The Company shall endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common
Stock upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange, over-the-counter
market or such other market on which the Common Stock is then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the
first conversion of the Securities into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such
automated quotation system or exchange at such time. 
 Section 4.04 Adjustment to Conversion Rate Upon a Make-Whole Fundamental
Change. (a) If and only to the extent that a Holder converts its Securities in connection with a Make-Whole Fundamental Change that occurs prior to May 15, 2022, the Company shall, under the circumstances set forth in this
Section 4.04, increase the Conversion Rate for the Securities so surrendered for conversion by a number of additional shares (the “Additional Shares”), as described below. 

(b) Upon surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy
its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 4.02. However, if the consideration for the Common Stock in any Make-Whole Fundamental Change described
in clause (c) of the definition of Fundamental Change is composed entirely of cash, for any conversion of the Securities following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based
solely on the Stock Price for the transaction and shall be deemed to be an amount in cash per $1,000 principal amount of converted Securities equal to the Conversion Rate (including any increase to reflect the Additional Shares as described in this
Section 4.04), multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify
Holders of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

  
 28 

 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased
shall be determined by reference to the table set forth in clause (f) below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock
Price”) paid (or deemed to be paid) per share of Common Stock in such Make-Whole Fundamental Change. If holders of Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause
(c) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock on each of the five
consecutive Trading Days prior to, but excluding, the Effective Date of the Make-Whole Fundamental Change. 
 (d) A conversion of Securities
by a Holder shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the Conversion Notice is received by the Conversion Agent on or after the Effective Date of the Make-Whole Fundamental Change and
prior to the close of business on the Business Day immediately preceding 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 carve-out in subsection (ii) of clause (c) of the definition of Fundamental Change, the 35th Trading Day following the actual Effective Date of the Make-Whole Fundamental Change). 

(e) The Stock Prices set forth in the first row of the following table (i.e., the column headings) shall be adjusted as of any date on which
the Conversion Rate is adjusted pursuant to Section 4.05. 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 the 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 will be adjusted in the same manner, at the same
time and for the same events as the Conversion Rate as set forth in Section 4.05. 
 (f) The following table sets
forth the number of Additional Shares by which the Conversion Rate for the Securities will be increased per $1,000 principal amount of Securities 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 or the Effective Date is between two Effective Dates in the
table, the number of Additional Shares by which the Conversion Rate for the Securities will be increased shall be determined by 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 365-day year; 

(ii) if the Stock Price is more than $30.00 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate; and 

  
 29 

 (iii) if the Stock Price is less than $5.00 per share (subject to adjustment
in the same manner as the Stock Prices set forth in the column headings of the table), 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 Securities exceed 200.0000 shares of
Common Stock, subject to adjustment in the same manner, at the same time and for the same events as the Conversion Rate as set forth in Section 4.05. 

Section 4.05 Conversion Rate Adjustments. The Conversion Rate shall be adjusted from time to time by the Company, upon the
occurrence of any of the following events, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Securities participate (other than in the case of a share split or share combination), at the same time and
upon the same terms as holders of the Common Stock and solely as a result of holding the Securities, in any of the events described in this Section 4.05, without having to convert their Securities 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 Securities held by such Holder. 

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of its 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 Ex-Dividend 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 Ex-Dividend Date or effective date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date; and
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after, and solely as a result of, giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 4.05(a) shall become effective immediately after the open of
business on the Ex-Dividend 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 4.05(a) is declared but not so paid or made, or any share split or share combination of the type described in this Section 4.05(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 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 share combination had not been
announced. 
 (b) If the Company issues to all or substantially all holders of its Common Stock any rights, options or warrants entitling
them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of 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 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: 

 
 

 

  
 30 

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend 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 the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the ten 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 4.05(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 Ex-Dividend Date for such issuance. To the extent that shares of 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 Ex-Dividend Date for such issuance had not occurred. 
 For purposes of this
Section 4.05(b) and for the purpose of Section 4.01(d)(i), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less
than such average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for 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. 
 (c) If the Company distributes shares of its Capital Stock,
evidences of its indebtedness, other assets or property 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 as to which an adjustment was effected pursuant to Section 4.05(a) or Section 4.05(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected
pursuant to Section 4.05(d) and (iii) Spin-Offs as to which the provisions set forth below in this Section 4.05(c) shall apply, then 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 Ex-Dividend Date for such distribution;

  
 31 

					
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors) of the shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the
Company (the “Distributed Property”) with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

 Any increase made under the portion of this Section 4.05(c) above shall become
effective immediately after the open of business on the Ex-Dividend 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. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined
above), in lieu of the foregoing increase, each Holder of a Security 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 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 on the Record Date for the distribution. If the Board of Directors determines the
“FMV” (as defined above) of any distribution for purposes of this Section 4.05(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 five consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date
for such distribution. 
 With respect to an adjustment pursuant to this Section 4.05(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;
			
	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 if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period after, and including, the Ex-Dividend 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.

 For purposes of the foregoing, “FMV0” will
be determined by reference to (i) the actual trading market for the Capital Stock or similar equity interest to be distributed in the Spin-Off or (ii) for any Trading Day in the Valuation Period as
of which such Capital Stock or similar equity interest has not commenced trading in the actual trading market for such security, the when-issued trading market for such security, as applicable. 

  
 32 

 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last
Trading Day of the Valuation Period; provided that in respect of any conversion of Securities during the Valuation Period, references in the portion of this Section 4.05(c) related to Spin-Offs to ten Trading Days
shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in
determining the Conversion Rate. If the Ex-Dividend Date of the Spin-Off is after the tenth Trading Day immediately preceding, and including, the end of the Observation
Period in respect of a conversion of Securities, references in the portion of this Section 4.05(c) related to Spin-Offs to ten Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such
lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the last Trading Day of such Observation
Period. 
 For purposes of this Section 4.05(c) (and subject in all respect to
Section 4.09), rights, options or warrants distributed by the Company, pursuant to a shareholder rights plan to all or substantially all holders of its 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 4.05(c) (and no adjustment to the Conversion Rate under this Section 4.05(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 4.05(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 Ex-Dividend 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 4.05(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 (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or 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 4.05(a), Section 4.05(b) and this Section 4.05(c), any dividend or distribution to which this Section 4.05(c) is applicable that also
includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which Section 4.05(a) is
applicable (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which
Section 4.05(b) is applicable (the “Clause B Distribution”), 
 then (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 4.05(c) is applicable (the “Clause C Distribution”) and any
Conversion Rate adjustment required by this Section 4.05(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 4.05(a) and Section 4.05(b) with respect thereto shall then be made, except that, if determined by the
Company (I) the “Ex-Dividend  

  
 33 

 
Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend 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 Ex-Dividend
Date or effective date” within the meaning of Section 4.05(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of
Section 4.05(b). 
 (d) If the Company makes any cash dividend or distribution to all or substantially all holders
of the Common Stock, 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 Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company distributes to holders of its Common Stock.

 Any increase pursuant to this Section 4.05(d) shall become effective immediately
after the open of business on the Ex-Dividend 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 not to make or pay such dividend or distribution, to 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 Security shall receive, for each $1,000 principal amount of Securities, 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 on the Ex-Dividend Date for such cash dividend or distribution. 
 (e) If the Company or any of its Subsidiaries
makes a payment in respect of a tender or exchange offer for the Common Stock, 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 ten 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 offer or exchange offer, as the case
may be, 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 Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer
expires;

  
 34 

					
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the tenth Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) 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 date such tender or exchange offer expires (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 date such tender or exchange offer expires (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 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 The adjustment to the Conversion Rate under this Section 4.05(e) shall occur at the
close of business on the tenth Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion of Securities within the ten Trading
Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references with respect to ten Trading Days 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
Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Securities, references in the preceding paragraph to ten Trading Days shall be deemed to be replaced, solely in respect of that
conversion, 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 of such Observation Period. For the
avoidance of doubt, no adjustment under this Section 4.05(e) will be made if such adjustment would result in a decrease in the applicable Conversion Rate. 

(f) Notwithstanding this Section 4.05 or any other provision of this Indenture or the Securities, if a Conversion
Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Securities on or after such Ex-Dividend Date and on or prior to the
related Record Date would be treated as the record holder of the Common Stock as of the related Conversion Date as described under Section 4.02(j) based on an adjusted Conversion Rate for such
Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 4.05, the Conversion Rate adjustment relating to such
Ex-Dividend 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 its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible or exchangeable
securities. In addition, the Company shall not adjust the Conversion Rate for guarantees issued in respect of any of its outstanding securities. 

(h) In addition to those adjustments required by subsections (a), (b), (c), (d) and (e) of this
Section 4.05, and to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ Global Select Market, the Company from time to time may increase the Conversion Rate by any amount for any period
of at least 20 Business Days if the Board of Directors has determined 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, as the Board of Directors
considers advisable, to avoid or diminish any income tax to holders of Common Stock or rights 

  
 35 

 
to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for tax purposes. Whenever the Conversion Rate is
increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Security at its last address appearing on the register of the Primary Registrar a notice of the increase at least 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. 

(i) Notwithstanding anything to the contrary in this Section 4.05, 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 its Subsidiaries; 

(iii) on account of ordinary course of business stock repurchases, including structured or derivative transactions, pursuant to
a stock repurchase program approved by the Board of Directors, in each case, that are not tender offers referred to in Section 4.05(e) of the adjustments above; 

(iv) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right (other than rights under a
shareholder rights plan as described in Section 4.09) or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection (i) and outstanding as of the date the Securities
were first issued; 
 (v) solely for a change in the par value of the Common Stock; or 

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

(j) All calculations and other determinations in respect of the Conversion Rate shall be made by the Company to the nearest 1/10,000th of a
share. 
 (k) Whenever the Conversion Rate is adjusted pursuant to this Section 4.05, the Company shall compute the
adjusted Conversion Rate in accordance with this Section 4.05 and shall prepare an Officers’ Certificate setting forth (i) the adjusted Conversion Rate, (ii) the subsection of this
Section 4.05 pursuant to which such adjustment has been made, showing in reasonable detail the facts upon which such adjustment is based, (iii) the calculation of such adjustment and (iv) the date as of which such
adjustment is effective, and such Officers’ Certificate shall promptly be delivered to the Trustee and each Conversion Agent (which certificates shall be conclusive evidence of the accuracy of such adjustment absent manifest error). As soon as
practicable after each such adjustment, the Company shall deliver to the Holders a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate. Unless and until a Responsible Officer of the Trustee and
each Conversion Agent shall receive an Officers’ Certificate with respect to an adjustment of the Conversion Rate, the Trustee and each Conversion Agent may assume without inquiry that the Conversion Rate has not been adjusted and that the last
Conversion Rate of which it has knowledge remains in effect. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to
exhibit the same to any Holder of Securities desiring inspection thereof at its office during normal business hours. Promptly following (and in any event, within one Business Day of) an adjustment of the Conversion Rate, the Company shall
disseminate a press release detailing the new Conversion Rate and other relevant information. 
 (l) For purposes of this
Section 4.05, the number of shares of Common Stock at any time outstanding shall not include shares 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 issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

  
 36 

 (m) The Company shall not take any voluntary action that would result in an adjustment
pursuant to any of the provisions described in clauses (b) through (e) of Section 4.05 or Section 4.04 without complying, if applicable, with the shareholder approval rules of the NASDAQ
Global Stock Market (including NASDAQ Stock Market Rule 5635, which requires shareholder approval of certain issuances of Common Stock) or any similar rule of any other stock exchange on which the Common Stock is listed at the relevant time. 

(n) In the event of a taxable distribution to holders of shares of Common Stock that results in an adjustment of the Conversion Rate, Holders
may, in certain circumstances, be deemed to have received a distribution subject to U.S. federal income tax as a dividend; in certain other circumstances, the absence of such an adjustment may result in a taxable dividend to the holders of shares of
Common Stock. Because this deemed distribution would not give rise to any cash from which any applicable withholding tax could be satisfied, if withholding taxes (including any backup withholding) are paid on behalf of a Holder, those withholding
taxes may be set off against payments of cash or Common Stock, if any, payable on the Securities (or, in some circumstances, against any payments on the Common Stock). 

(o) Notwithstanding any of the foregoing, if: 

(i) the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation through Combination Settlement and
shares of Common Stock are deliverable to settle the Daily Settlement Amount for a given Trading Day within the Observation Period applicable to Securities that a Holder has converted; 

(ii) any distribution or transaction described in subsections (a), (b), (c), (d) and
(e) of this Section 4.05 has not yet resulted in an adjustment to the Conversion Rate on the Trading Day in question; and 

(iii) the shares of Common Stock that such Holder will receive in respect of such Trading Day are not entitled to participate
in the relevant distribution or transaction (because such shares of Common Stock were not held on a related Record Date or otherwise), 

then such Holder will be treated as if such Holder were the record owner of such shares of Common Stock on an unadjusted basis and participate
in the related dividend, distribution or other event giving rise to such adjustment and the Company shall take such corporate actions as required to give effect to the foregoing. 

Notwithstanding any of the foregoing, if: 

(i) the Company elects to satisfy (or is otherwise required to satisfy) its Conversion Obligation solely in shares of Common
Stock (other than cash in lieu of any fractional shares); 
 (ii) any distribution or transaction described in subsections
(a), (b), (c), (d) and (e) of this Section 4.05 has not yet resulted in an adjustment to the Conversion Rate on a given Conversion Date; and 

(iii) the shares of Common Stock deliverable on settlement of the related conversion are not entitled to participate in the
relevant distribution or transaction (because such shares of Common Stock were not held on a related Record Date or otherwise), 
 then such
Holder will be treated as if such Holder were the record owner of such shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment and the Company shall take such
corporate actions as required to give effect to the foregoing. 

  
 37 

 Section 4.06 Adjustments of Prices. Whenever any provision of this Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock
Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments 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 of the event occurs, at any time during the relevant period. 

Section 4.07 Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination), 
 (ii) any consolidation, merger or combination involving the Company, 

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s
Subsidiaries substantially as an entirety 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 “Merger Event”), then the Company or the successor or purchasing company, as the case may be, will execute with the Trustee (as required pursuant to this Indenture), without the
consent of the Holders (except as required pursuant to this Indenture), a supplemental indenture providing that, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities shall be changed
into a right to convert such principal amount of Securities 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 Merger 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 Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall
execute with the Trustee a supplemental indenture permitted under Section 10.01(f) providing for such change in the right to convert each $1,000 principal amount of Securities; provided, however, that at and
after the effective time of the Merger Event, (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Securities in accordance with
Section 4.02 and (B)(I) any amount payable in cash upon conversion of the Securities in accordance with Section 4.02 shall continue to be payable in cash, (II) any shares of Common Stock that
the Company would have been required to deliver upon conversion of the Securities in accordance with Section 4.02 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 Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property that a holder of one share of Common Stock would have received in
such transaction. If the Merger 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 shareholder election), then the Reference
Property into which the Securities will be convertible shall be deemed to be (i) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (ii) if no
holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee)
of the weighted average as soon as practicable after the determination is made. 
 Such supplemental indenture shall provide for
anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for in this Article 4. If the Reference Property in respect of any Merger Event includes shares of stock, securities or other property
or assets of a Person other than the successor or 

  
 38 

 Purchasing corporation, as the case may be, in such Merger Event, such other Person will also execute such
supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to purchase their Securities upon a Fundamental Change
pursuant to Article 3, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. 
 If the holders of
Common Stock receive only cash in such Merger Event, then for all conversions of Securities that occur after the effective date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Securities shall
be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased pursuant to Section 4.04), multiplied by the price paid per share of Common Stock in such Merger Event
and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly
equivalent as is possible to the adjustments provided for in this Article 4. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination
thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect
the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the
repurchase rights set forth in Article 3. 
 (b) In the event the Company shall execute a supplemental indenture pursuant to
subsection (a) of this Section 4.07, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or
asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company
shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the register of the Primary Registrar provided for in this Indenture, within 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 Merger Event unless its terms are consistent with this Section 4.07. None of the foregoing provisions shall affect the right of a Holder of Securities to convert its Securities into cash, shares of Common Stock or a
combination of cash and shares of Common Stock, as applicable, as set forth in Section 4.01 and Section 4.02 prior to the effective date of such Merger Event. 

(d) The above provisions of this Section 4.07 shall similarly apply to successive Merger Events. 

Section 4.08 Cancellation of Converted Securities. All Certificated Securities delivered for conversion shall be delivered to the
Trustee or its agent to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in this Indenture. Upon conversions of beneficial interests in any Global Security, the Trustee or the Securities Custodian, at
the direction of the Trustee, shall reduce the aggregate principal amount of outstanding Securities represented by such Global Security to reflect the conversion. 

Section 4.09 Shareholders Rights. If the Company has a shareholder rights plan in effect upon conversion of the Securities, each
share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, 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 shareholder rights plan, as the same may be amended from time to time (such rights prior to separation from the Common Stock, “Non-Separate
Rights”). However, if prior to any conversion the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan so that the Holders would not be entitled to receive any
rights in respect of Common Stock, if any, issuable upon conversion of the Securities, the Conversion Rate shall be increased at the time of separation as if the Company distributed to all or substantially all holders of Common Stock shares of
Capital Stock of the Company, evidences of its indebtedness, 

  
 39 

 other assets or property or rights, options or warrants to acquire its Capital Stock or other securities as
provided in Section 4.05(c), subject to decrease in the event of the expiration, termination or redemption of such rights. A distribution of rights pursuant to such a shareholder rights plan shall not trigger a Conversion
Rate adjustment pursuant to Section 4.05(c) if Holders of the Securities participate in such distribution on an as-converted basis in accordance with the first paragraph of
Section 4.05. 
 Section 4.10 Trustee’s Disclaimer. The Trustee shall have no duty
to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected
in relying upon, the Officers’ Certificate that the Company is obligated to deliver to the Trustee pursuant to Section 4.05(k). The Trustee makes no representation as to the validity or value of any securities or
assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article 4. The Trustee and the Conversion Agent (if other than the Trustee) shall have
no responsibility for determination of the Daily Settlement Amounts (if applicable) or the Daily Conversion Values (if applicable). In addition, in no event shall the Trustee or Conversion Agent be responsible for making any calculations under this
Indenture or for determining amounts to be paid or for monitoring any Stock Price. For the avoidance of doubt, the Trustee and the Conversion Agent shall rely conclusively on the calculations and information provided to them by the Company as to the
Daily VWAP, Trading Price, Daily Conversion Value, Daily Settlement Amount and Last Reported Sale Price. Nor shall the Trustee or the Conversion Agent be charged with knowledge of or have any duties to monitor any Measurement Period or Observation
Period. 
 The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental
indenture executed pursuant to Section 6.01, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate with respect thereto which the
Company is obligated to file with the Trustee pursuant to Section 6.01. 
 ARTICLE 5

 (c) At any time the Company is not
subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Securities or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the
meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Securities or any shares of Common Stock issuable upon conversion of such
Securities, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Securities or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any
Holder or beneficial owner of such Securities or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Securities or shares of Common Stock in accordance with Rule
144A, as such rule may be amended from time to time. 
 (d) If, at any time during the six-month

Affiliate Securities) are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months preceding (as a result of restrictions pursuant to
U.S. securities laws or the terms of this Indenture or the Securities), the Company shall pay Additional Interest on the Securities. Such Additional Interest shall accrue on the Securities at the rate of 0.25% per annum of the principal amount of
the Securities outstanding for each day during the first 90-day period for which the Company’s failure to file has occurred and is continuing or the Securities are not otherwise freely tradable by Holders
other than the Company’s Affiliates (or Holders that have been the Company’s Affiliates at any time during the three months preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities,
and 0.50% per annum for each day during such period thereafter. As used in this Section 5.02(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

Affiliate Securities) are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months preceding (without restrictions pursuant to U.S.
securities laws or the terms of this Indenture or the Securities) as of the 375th day after the last date of original issuance of the Securities, the Company shall pay Additional Interest on the Securities at a rate equal to 0.50% per annum of the
principal amount of Securities outstanding until the restrictive legend on the Securities has been removed in accordance with Section 2.06(d), the terms of this Indenture and the Securities, the Securities are assigned an
unrestricted CUSIP and the Securities are freely tradable by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months preceding) (without restrictions pursuant to U.S.
securities laws or the terms of this Indenture or the Securities). 
 (f) Additional Interest will be payable in arrears on each Interest
Payment Date following accrual in the same manner as regular interest on the Securities. 
 (g) The Additional Interest that is payable in
accordance with Section 5.02(d) or Section 5.02(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to
Section 7.04. 

  
 41 

 (h) If Additional Interest is payable by the Company pursuant to
Section 5.02(d) or Section 5.02(e), the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (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 a certificate, the Trustee may assume without inquiry that no such Additional Interest
is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 

(i) For the avoidance of doubt, the provisions of Sections 5.02(d) and (e) shall not apply to Affiliate Securities, and no
Additional Interest pursuant to Section 5.02(d) and (e) shall be payable on Affiliate Securities. 

Section 5.03 Compliance Certificates. 

(a) The Company shall deliver to the Trustee within 120 days after the end of each fiscal year during which any Securities were
outstanding an Officers’ Certificate stating whether or not the signer thereof knows of any Default or Event of Default that occurred during such fiscal year and that the Company has complied with all conditions and covenants under this
Indenture. For purposes of this Section 5.03, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture. If the officer of the Company signing such
Officers’ Certificate has knowledge of such a Default or Event of Default, the Officers’ Certificate shall describe any such Default or Event of Default and its status. 

(b) The Company shall, so long as any of the Securities are outstanding, deliver to the Trustee, forthwith, and in any event within five
Business Days, upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 

Section 5.04 Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

necessary to preserve and keep in full force and effect its corporate existence. 
 Section 5.06 Stay, Extension and Usury Laws.
The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would
prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of
this Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 

ARTICLE 6 

CONSOLIDATION, MERGER, SALE, CONVEYANCE, TRANSFER OR LEASE 

Section 6.01 Company May Consolidate, Etc., Only on Certain Terms. The Company shall not, directly or indirectly, consolidate with
or merge with or into any other Person (in a transaction in which the Company is not the surviving corporation) or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person (other than a wholly-owned
Subsidiary in existence on or created after the date of this Indenture), unless: 

  
 42 

 (a) in case the Company shall consolidate with or merge into another Person (in a
transaction in which the Company is not the surviving corporation) or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, the Person formed by such consolidation or into which the Company is
merged or the Person which acquires by sale, conveyance or transfer, or which leases, all or substantially all of the properties and assets of the Company (in each case, the “Successor Company”) shall: 

(i) be (and, if the Company remains a party to this Indenture after the relevant transaction, the Company is) a corporation or
limited liability company organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia; provided, in each case, that the property into which the Securities shall be convertible
shall be the stock or other equity of an entity that is a corporation for U.S. federal income tax purposes; and 
 (ii)
expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and interest on all the Securities and the performance or observance
of every covenant of this Indenture on the part of the Company to be performed or observed and the conversion rights shall be provided for in accordance with Article 4, by supplemental indenture satisfactory in form to the Trustee, executed
and delivered to the Trustee, by such Successor Company (if other than the Company); 
 (b) immediately after giving effect to such
transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing; and 

(c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, sale, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article 6 and that all conditions precedent herein provided for
relating to such transaction have been complied with. 
 Section 6.02 Successor Substituted. Upon any consolidation of the
Company with, or merger of the Company into, any other Person or any sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company in accordance with Section 6.01, there shall
be an adjustment to the Conversion Rate and the Successor Company shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such Successor Company had been named
as the Company herein, and thereafter, except in the case of a lease, the Company shall be relieved of all obligations and covenants under this Indenture and the Securities. 

ARTICLE 7 
 DEFAULT AND
REMEDIES 
 Section 7.01 Events Of Default. An “Event of Default” shall occur if: 

(1) the Company fails to pay the principal of any Security when due and payable at its stated maturity, upon any required repurchase, upon
declaration of acceleration or otherwise; 
 (2) the Company fails to pay the interest on any Security when due and payable and such failure
continues for a period of 30 days; 
 (3) the Company fails to convert any Security in accordance with this Indenture upon exercise of a
Holder’s conversion right for a period of five Business Days; 
 (4) the Company fails to provide timely notice pursuant to
Section 3.02(a), Section 3.02(b), Section 4.01(d), Section 4.01(e) or Section 4.04(b), in each case when due; 

(5) the Company fails to comply with its obligations set forth in Article 6; 

  
 43 

 (6) the Company fails to perform any other agreement required of it in this Indenture or the
Securities and such failure continues for 60 days after written notice is given in accordance with the immediately succeeding paragraph; 

(7) any indebtedness for money borrowed by the Company or any of its Significant Subsidiaries (or any group of Subsidiaries that, taken
together, would constitute a Significant Subsidiary) in an aggregate outstanding principal amount in excess of $25,000,000 is not paid at final maturity or upon acceleration, and such indebtedness is not discharged, or such acceleration is not cured
or rescinded, within 30 days after written notice is given in accordance with the immediately succeeding paragraph; 
 (8) the Company or any
of its Significant Subsidiaries (or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary) fails to pay one or more final and non-appealable judgments entered by a court or
courts of competent jurisdiction, the aggregate uninsured or unbonded portion of which is in excess of $25,000,000, if the judgments are not paid, discharged or stayed within 30 days; 

(9) the Company or any Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 

(A) commences a voluntary case or proceeding; 

(B) consents to the entry of an order for relief against it in an involuntary case or proceeding; 

(C) consents to the appointment of a Custodian of it or for all or substantially all of its property; or 

(D) makes a general assignment for the benefit of its creditors; or 

(10) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against the Company or any Significant Subsidiary in an involuntary case or proceeding; 

(B) appoints a Custodian of the Company or any Significant Subsidiary or for all or substantially all of the property of the Company or any
Significant Subsidiary; or 
 (C) orders the liquidation of the Company or any Significant Subsidiary; 

and in each case the order or decree remains unstayed and in effect for 60 consecutive days. 

The notice given pursuant to this Section 7.01 must specify the default, demand that it be remedied and state that
the notice is a “Notice of Default.” When any default under this Section 7.01 is cured, it ceases. 

Section 7.02 Acceleration. If an Event of Default (other than an Event of Default specified in clause (9) or (10) of
Section 7.01) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the
Trustee, declare all unpaid principal to the date of acceleration on the Securities then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an
Event of Default specified in clause (9) or (10) of Section 7.01 occurs, all unpaid principal of the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder. After any acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the Securities may, except with respect to the nonpayment
of principal (including the Fundamental Change Repurchase Price) or interest or with respect to the failure to pay and/or deliver the consideration due upon conversion, rescind and annul such acceleration by notice to the Trustee if (a) all
existing Events of Default, other than the non-payment of accelerated principal, have been cured or waived; (b) to the extent the payment of such interest is lawful, interest (calculated at the rate per
annum 

  
 44 

 borne by the Securities plus one percent) on overdue installments of interest and overdue principal, which
has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any
predecessor Trustee under Section 8.07 have been made. No such rescission shall affect any subsequent default or impair any right consequent thereto. 

Section 7.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to,
pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative to the extent permitted by law. 
 Section 7.04 Additional Interest. 

(a) Notwithstanding anything in this Indenture or in the Securities to the contrary, to the extent the Company elects, the sole remedy for an
Event of Default during the first 180 days after the occurrence of an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 5.02(a), shall after the occurrence of
such an Event of Default consist exclusively of the right to receive Additional Interest on the Securities at a rate equal to (i) for the first 90 days after the occurrence of such an Event of Default, 0.25% per annum of the principal amount of
the Securities outstanding for each day during which such Event of Default is continuing during such period, beginning on, and including, the date on which such an Event of Default first occurs, and (ii) for the 90 days after the 91st day after
the occurrence of such an Event of Default, 0.50% per annum of the principal amount of the Securities outstanding for each day during which such Event of Default is continuing during such period. Additional Interest payable pursuant to this
Section 7.04 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 2.06(d) or Section 2.06(e). 

(b) 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 Securities. On the 181st day after such Event of Default (if such Event of Default is not cured or waived prior to such 181st day), the Securities will be subject to acceleration as provided in Section 7.02. This
Section 7.04 shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. If the Company does not elect to pay Additional Interest following an Event of Default in accordance with
this Section 7.04, or if it so elects but fails to pay the Additional Interest when due, the Securities shall be immediately subject to acceleration as provided in Section 7.02. To elect to pay
Additional Interest as the sole remedy during the first 180 days after the occurrence of an Event of Default relating to the failure to comply with the reporting obligations in accordance with subsection (a) of this
Section 7.04 and this subsection (b), the Company must notify all Holders of the Securities, the Trustee and the Paying Agent of such election prior to the beginning of such
180-day period. Upon the Company’s failure to timely give such notice or if the Company gives such notice but does not pay the Additional Interest when due, the Securities shall be immediately subject to
acceleration as provided in Section 7.02. 
 (c) In no event will the Additional Interest described in this
Section 7.04, together with any Additional Interest that may accrue as a result of the Company’s failure to timely file any document or report that the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act, as applicable, as provided in Section 5.02, accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving
rise to the requirement to pay such Additional Interest. 
 Section 7.05 Waiver of Defaults and Events of Default. Subject to
Section 7.08 and Section 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing default or Event of Default
and its consequence, except (a) a default or Event of Default in the payment of the principal (including the Fundamental Change Repurchase Price) of or interest on any Security, (b) a 

  
 45 

 failure by the Company to convert any Securities in accordance with the provisions of the Securities and
this Indenture or (c) any default or Event of Default in respect of any provision of this Indenture or the Securities that, under Section 10.02, cannot be modified or amended without the consent of the Holder of each
Security affected. When a default or Event of Default is waived, it is cured and ceases. 
 Section 7.06 Control by Majority.
The Holders of a majority in aggregate principal amount of the outstanding Securities will 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 Securities. However, the Trustee may refuse to follow any direction that violates law or this Indenture or that would result in the Trustee incurring personal liability unless the Trustee is offered
reasonable indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. 

Section 7.07 Limitations on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Securities (except
actions for the enforcement of payment of the principal (including the Fundamental Change Repurchase Price) or interest on any Security on or after the applicable due date or the right to convert the Securities or to receive the consideration due
upon such conversion in accordance with Article 4) unless: 
 (1) the Holder has previously given the Trustee written
notice of a continuing Event of Default; 
 (2) the Holders of at least 25% in aggregate principal amount of the Securities
then outstanding have made a written request and have offered to the Trustee reasonable indemnity satisfactory to the Trustee to institute such proceeding as Trustee; and 

(3) the Trustee has failed to institute such proceeding within 60 days after such notice, request and offer, and has not
received from the Holders of a majority in aggregate principal amount of the Securities then outstanding a direction inconsistent with such request within 60 days after such notice, request and offer. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder.

 Section 7.08 Rights of Holders to Receive Payment and to Convert. Each Holder shall have the right to receive payment or
delivery, as the case may be, of (a) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (b) accrued and unpaid interest, if any, on, and (c) the consideration due upon conversion of, its Securities,
on or after the respective due dates expressed or provided for in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, and such right to receive payment or delivery, as the case may be, on or
after such respective dates shall not be impaired or affected without the consent of such Holder. 
 Section 7.09 Collection Suit By
Trustee. If an Event of Default in the payment of principal or interest specified in clause (1) or (2) of Section 7.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an
express trust against the Company or another obligor on the Securities for the whole amount of principal and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and
on overdue installments of interest, in each case at the rate per annum borne by the Securities plus one percent and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel. 
 Section 7.10 Trustee May File Proofs of Claim.
The Trustee may file such proofs of claim and other papers or documents as may be 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 the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money
or other property 

  
 46 

 payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee 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 to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.07, and to the extent that such payment of the reasonable
compensation, expenses, disbursements and advances 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, money, securities and other
property which the Holders 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, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the Securities 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. 
 Section 7.11 Priorities. If the Trustee collects any money pursuant to this
Article 7, it shall pay out the money in the following order: 
 FIRST, to the Trustee for amounts due under
Section 8.07; 
 SECOND, to Holders for amounts due and unpaid on the Securities for principal and interest,
ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and 

THIRD, to the Company or such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.11. 

Section 7.12 Undertaking For Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit

 Section 8.03 [Reserved]. 

Section 8.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to

actually known to a Responsible Officer of the Trustee in accordance with the terms of this Indenture, the Trustee shall mail to each Holder notice of the Default or Event of Default within 90 days after it receives notice thereof. However, the
Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding notice is in the interests of Holders, except in the case of a Default or an Event of Default in (a) payment of
the principal of (including the Fundamental Change Repurchase Price, if applicable) or interest on any Security or (b) payment or delivery, as the case may be, of the consideration due upon conversion. 

Section 8.06 [Reserved]. 

Section 8.07 Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation (as agreed to
from time to time by the Company and the Trustee in writing) for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company shall reimburse the Trustee
promptly upon request for all reasonable disbursements, expenses and advances incurred or made by it in addition to the compensation for its services. Such expenses may include the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel. 
 The Company shall indemnify each of the Trustee and any predecessor Trustee against any and all
losses, liabilities, damages, claims or expenses (including taxes, other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 8.07) and defending itself against any claim (whether asserted by the Company or any
Holder 

  
 49 

 
or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee, upon receiving written notice thereof, shall notify the
Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the
defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its written consent, which consent shall not be unreasonably
withheld. 
 The Company need not reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by it
resulting from its negligence, bad faith or willful misconduct. 
 To secure the Company’s payment obligations in this
Section 8.07, the Trustee shall have a senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee, except such money or property held in trust to pay the
principal of, interest on, and amounts due upon conversion of, the Securities. 
 When the Trustee incurs expenses or renders services after
an Event of Default specified in clause (7) or (8) of Section 7.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law. The obligations of the Company under this Section 8.07 shall survive the termination or satisfaction and discharge of this Indenture or the resignation or removal of the
Trustee for any reason. 
 Section 8.08 Replacement of Trustee. The Trustee may resign by so notifying the Company in writing
and by mailing notice thereof to the Holders at their addresses as they appear on the Primary Registry. The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and
the Company in writing and may, with the Company’s written consent, appoint a successor Trustee. The Company may remove the Trustee if: 

(1) the Trustee fails to comply with Section 8.10; 

(2) the Trustee is adjudged a bankrupt or an insolvent or relief is entered with respect to the Trustee under any Bankruptcy Law; 

(3) a receiver or other public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint a
successor Trustee. The resignation or removal of a Trustee shall not be effective until a successor Trustee shall have delivered the written acceptance of its appointment as described below. 

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company
or the Holders of 10% in principal amount of the Securities then outstanding may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Company. 

If the Trustee fails to comply with Section 8.10, any Holder who has been a Holder for at least six months may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor
Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee (provided that
all sums owing to the Trustee hereunder have been paid) and be released from its obligations (exclusive of any liabilities that the retiring Trustee may have incurred while acting as Trustee) hereunder, the resignation or removal of the retiring
Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder. 

  
 50 

 A retiring Trustee shall not be liable for the acts or omissions of any successor Trustee
after its succession. 
 Notwithstanding replacement of the Trustee pursuant to this Section 8.08, the
Company’s obligations under Section 8.07 shall continue for the benefit of the retiring Trustee. 

Section 8.09 Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or
substantially all of its corporate trust assets (including the administration of this Indenture) to, another corporation, by sale or otherwise, the resulting, surviving or transferee corporation, without any further act, shall be the successor
Trustee, provided such transferee corporation shall qualify and be eligible under Section 8.10. Such successor Trustee shall promptly mail notice of its succession to the Company and each Holder. 

Section 8.10 Eligibility; Disqualification. The Trustee (or its parent holding company) shall have a combined capital and surplus
of at least $50,000,000. If at any time the Trustee shall cease to satisfy such requirement, it shall resign immediately in the manner and with the effect specified in this Article 8. 

Section 8.11 [Reserved]. 

ARTICLE 9 
 SATISFACTION
AND DISCHARGE OF INDENTURE 
 Section 9.01 Satisfaction And Discharge Of Indenture. This Indenture shall upon request of the
Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all
Securities theretofore authenticated and delivered (other than Securities that have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07) have been delivered to the Trustee for
cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Securities have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or
otherwise, cash or cash and/or, solely to satisfy the Company’s Conversion Obligation, shares of Common Stock, as applicable, sufficient to pay all of the outstanding Securities and all other sums due and payable under this Indenture by the
Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have
been complied with. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under
Section 8.07 shall survive and, if money shall have been deposited with the Trustee pursuant to paragraph (a)(ii) of this Section 9.01, the provisions of Section 9.02 and
Section 9.04 shall survive until the Securities have been paid in full. 
 Section 9.02 Application of
Trust Money. Subject to the provisions of Section 9.03, the Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money and shares of Common Stock deposited with it pursuant to
Section 9.01 and shall apply the deposited money and shares of Common Stock in accordance with this Indenture and the Securities to the payment or delivery, as the case may be, of the principal of, and interest on, and the
consideration due upon conversion of, the Securities; provided that such money and shares of Common Stock need not be segregated from other funds except to the extent required by law. 

Section 9.03 Repayment to Company. The Trustee and each Paying Agent shall promptly pay to the Company upon request any excess
money or shares of Common Stock (i) deposited with them pursuant to Section 9.01 and (ii) held by them at any time. 

  
 51 

 The Trustee and each Paying Agent shall pay to the Company upon request any money or shares
of Common Stock held by them for the payment or delivery, as the case may be, of principal, interest or amounts due upon conversion that remains unclaimed for two years after a right to such money or shares of Common Stock has matured;
provided, however, that the Trustee or such Paying Agent, before being required to make any such payment or delivery, may at the expense of the Company cause to be mailed to each Holder entitled to such money or shares of Common Stock notice
that such money or shares of Common Stock remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money or shares of Common Stock then remaining will be
repaid or delivered to the Company. After payment or delivery to the Company, Holders entitled to money or shares of Common Stock must look to the Company for payment as general creditors unless an applicable abandoned property law designates
another Person. In the absence of a written request from the Company to return unclaimed funds or shares to the Company, the Trustee shall from time to time deliver all unclaimed funds or shares to or as directed by applicable escheat authorities,
as determined by the Trustee in its sole discretion, in accordance with the customary practices and procedures of the Trustee. Any unclaimed funds or shares held by the Trustee pursuant to this Section 9.03 shall be held
uninvested and without any liability for interest. 
 Section 9.04 Reinstatement. If the Trustee or any Paying Agent is unable
to apply any money or shares of Common Stock in accordance with Section 9.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time as the
Trustee or such Paying Agent is permitted to apply all such money or shares of Common Stock in accordance with Section 9.02; provided, however, that if the Company has made any payment or delivery, as the case may
be, of the principal of, interest on, or amounts due upon conversion of, any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment or
delivery from the money or shares of Common Stock held by the Trustee or such Paying Agent.

Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. The Holders
of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Securities without notice to any Holder. However,

(l) modify the provisions of Article 11 in a manner adverse to the Holders. 

It shall not be necessary for the consent of the Holders under this Section 10.02 to approve the particular form of

as aforesaid, and upon receipt by the Trustee of the documents described in Section 10.06 and Section 12.04, the Trustee shall join with the Company in the execution of such amended or supplemental
indenture unless such amended or supplemental indenture directly 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 amended or supplemental indenture. 

  
 53 

 After an amendment, supplement or waiver under this Section 10.02
becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amendment, supplement or waiver. 
 Section 10.03 [Reserved]. 

Section 10.04 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a
Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security.
However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of
clauses (a) through (l) of Section 10.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion
of a Security that evidences the same debt as the consenting Holder’s Security.

Securities. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Security thereafter authenticated. The Company in exchange for all Securities may issue and the Trustee shall, upon receipt of a Company

Section 10.06 Trustee to Sign Amendments, Etc. The Trustee shall sign any amendment or supplemental indenture authorized pursuant
to this Article 10 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or
refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with and, subject to Section 8.01, shall be fully protected in relying upon in addition to the documents required by
Section 12.04, an Officers’ Certificate and an Opinion of Counsel each stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or
supplement indenture until the Board of Directors approves it.

transfer instructions (“Instructions”) given by the Company pursuant to this Indenture and delivered using unsecured e-mail, facsimile transmission or other similar unsecured electronic
methods (including pdf files) (“Electronic Means”); provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (each, an
“Authorized Officer”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects
to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees
that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that Instructions that purport to have been sent by an Authorized Officer listed on the incumbency certificate
provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely
responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or
indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such Instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (a) to assume all risks arising out
of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; and (b) to notify the
Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

counsel, all such conditions precedent (including any covenants, compliance with which constitutes a condition precedent) have been complied with.

Indenture shall include:

 [FORM OF REVERSE OF SECURITY] 

GOGO INC. 
 6.00%
CONVERTIBLE SENIOR NOTES DUE 2022 
 This Security is one of a duly authorized issuance of Securities of the Company, designated as its
6.00% Convertible Senior Notes due 2022 (the “Securities”), limited in aggregate principal amount of up to $215,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Securities purchased by the
Initial Purchasers pursuant to the exercise of their option to purchase additional Securities as set forth in the Purchase Agreement), all issued or to be issued under and pursuant to an Indenture dated as of November 21, 2018 (the
“Indenture”), between the Company and U.S. Bank National Association (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 Securities. Additional Securities may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the
Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all
Securities may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Securities 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. In case an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, the principal of all Securities then outstanding shall ipso
facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
 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 and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a
Security to a Paying Agent to collect such payments in respect of the Security. 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
Securities, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding, evidenced as in the Indenture provided, to execute supplemental
indentures modifying the terms of the Indenture and the Securities 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 Securities at the time
outstanding may on behalf of the Holders of all of the Securities waive any past Default or Event of Default under the Indenture and its consequences. 

The Securities are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples 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, Securities may be exchanged for a like aggregate principal amount of Securities 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 Securities issued upon such exchange of Securities being different from the name of the Holder of the old Securities surrendered for such exchange. 

The Securities 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 Securities 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. 

  
 8 

 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option,
prior the close of business on the Business Day immediately preceding January 15, 2022 only upon the occurrence of certain conditions specified in the Indenture, and on or after January 15, 2022 until the close of business on the second
Scheduled Trading Day immediately preceding May 15, 2022 regardless of the occurrence of such conditions, to convert any of its Securities or portion thereof that is $1,000 or an integral multiple thereof, into shares of Common Stock or cash,
shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

All terms used in this Security but not specifically defined herein are defined in the Indenture and are used herein as so defined. 

In the case of any conflict between the provisions of this Security and the Indenture, the provisions of the Indenture shall control. 

This Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on this
Security. 
 THE INDENTURE AND THIS SECURITY, AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THE INDENTURE OR THIS
SECURITY, SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 The Company will furnish to any
Holder, upon written request and without charge, a copy of the Indenture. Requests may be made to: Gogo Inc., 111 North Canal St, Suite 1500, Chicago, Illinois 60606, Attention: General Counsel. 

[No Additional Interest shall be payable on this Security by the Company pursuant to Sections 5.02(d) and (e) of the Indenture.]5

Ladies and Gentlemen: 
 Gogo Inc., a Delaware
corporation (the “Company”), proposes to issue and sell to the several initial purchasers listed in Schedule 1 hereto (the “Initial Purchasers”), for whom you are acting as representatives (the
“Representatives”), $202 million principal amount of its 6.00% Convertible Senior Notes due 2022 (the “Underwritten Securities”) and, at the option of the Initial Purchasers, up to an additional
$32.25 million principal amount of its 6.00% Convertible Senior Notes due 2022 (the “Option Securities”) if and to the extent that the Initial Purchasers shall have determined to exercise the option to purchase such 6.00%
Convertible Senior Notes due 2022 granted to the Initial Purchasers in Section 2 hereof. The Underwritten Securities and the Option Securities are herein referred to as the “Securities.” The Securities will
be convertible into shares (the “Underlying Securities”) of common stock of the Company, par value $0.0001 per share (the “Common Stock”). The Securities will be issued pursuant to an indenture, to be dated as of
November 21, 2018 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). 

Entities affiliated with a director of the Company have agreed to purchase $8 million principal amount of the Company’s 6.00%
Convertible Senior Notes due 2022 (the “Affiliate Securities”) in a separate private placement pursuant to the exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”),
provided by Section 4(a)(2) thereof and the Company’s financial advisor has agreed to purchase $5 million principal amount of the Company’s 6.00% Convertible Senior Notes due 2022 (the “Advisor Securities” and,
together with the Affiliate Securities, the “Private Securities”) in a separate private placement pursuant to the exemption from registration under the Securities Act provided by Section 4(a)(2)

 
thereof (the purchase of the Affiliate Securities and the Advisor Securities, collectively, the “Private Placement”) as described in the Time of Sale Information and the Offering
Memorandum (each as defined below). The Private Securities will be convertible into shares of Common Stock (the “Private Underlying Securities”) and will be issued pursuant to the Indenture. 

The Company hereby confirms its agreement with the several Initial Purchasers concerning the purchase and sale of the Securities as follows:

 1. Offering Memorandum and Transaction Information. The Securities will be sold to the Initial Purchasers without being registered
under the Securities Act in reliance upon an exemption therefrom. The Company has prepared a preliminary offering memorandum, dated November 15, 2018 (the “Preliminary Offering Memorandum”), and will prepare an offering
memorandum, dated the date hereof (the “Offering Memorandum”), setting forth information concerning the Company and the Securities. Copies of the Preliminary Offering Memorandum have been, and copies of the Offering Memorandum will
be, delivered by the Company to the Initial Purchasers pursuant to the terms of this purchase agreement (this “Agreement”). The Company hereby confirms that it has authorized the use of the Preliminary Offering Memorandum, the other
Time of Sale Information (as defined below) and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers in the manner contemplated by this Agreement. References herein to the Preliminary
Offering Memorandum, the Time of Sale Information and the Offering Memorandum shall be deemed to refer to and include any document incorporated by reference therein and any reference to “amend,” “amendment” or
“supplement” with respect to the Preliminary Offering Memorandum or the Offering Memorandum shall be deemed to refer to and include any documents filed after such date and incorporated by reference therein. For purposes of this Agreement,
the “Time of Sale” is 6:00 p.m., New York City time, on the date of this Agreement. 
 At or prior to the Time of Sale, the
Company had prepared the following information (collectively, the “Time of Sale Information”): the Preliminary Offering Memorandum, as supplemented and amended by the written communications listed on Annex A hereto. 

2. Purchase and Resale of the Securities. 

(a) The Company agrees to issue and sell the Underwritten Securities to the several Initial Purchasers as provided in this Agreement, and each
Initial Purchaser, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of
Underwritten Securities set forth opposite such Initial Purchaser’s name in Schedule 1 hereto at a price equal to 97.50% of the principal amount thereof (the “Purchase Price”) plus accrued interest, if any, from
November 21, 2018 to the Closing Date (as defined below). 
 In addition, the Company agrees to issue and sell the Option Securities to
the several Initial Purchasers as provided in this Agreement, and the Initial Purchasers, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to
purchase, severally and not jointly, from the Company the Option Securities at the Purchase Price plus accrued interest, if any, from the Closing Date to the date of payment and delivery. 

  
 2 

 If any Option Securities are to be purchased, the principal amount of Option Securities to
be purchased by each Initial Purchaser shall be the principal amount of Option Securities which bears the same ratio to the aggregate principal amount of Option Securities being purchased as the principal amount of Underwritten Securities set forth
opposite the name of such Initial Purchaser in Schedule 1 hereto (or such amount increased as set forth in Section 10 hereof) bears to the aggregate principal amount of Underwritten Securities being purchased from
the Company by the several Initial Purchasers, subject, however, to such adjustments to eliminate Securities in denominations other than $1,000 as the Representatives in their sole discretion shall make. 

The Initial Purchasers may exercise the option to purchase the Option Securities at any time in whole, or from time to time in part, on or
before the thirteenth day beginning on, and including, the Closing Date, by written notice from the Representatives to the Company. Such notice shall set forth the aggregate principal amount of Option Securities plus accrued interest as to which the
option is being exercised and the date and time when the Option Securities are to be delivered and paid for which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date nor later
than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10 hereof). Any such notice shall be given at
least two business days prior to the date and time of delivery specified therein. Option Securities may be purchased as provided in this Section 2 in connection with the offering and distribution of the Underwritten
Securities. 
 (b) The Company understands that the Initial Purchasers intend to offer the Securities for resale on the terms set forth in
the Time of Sale Information. Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that: 
 (i)
it is a qualified institutional buyer within the meaning of Rule 144A under the Securities Act (a “QIB”) and an accredited investor within the meaning of Rule 501(a) of Regulation D under the Securities Act (“Regulation
D”); 
 (ii) it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell,
the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act; and

 (iii) it has not solicited offers for, or offered or sold, and will not solicit offers for, or offer or sell, the
Securities as part of their initial offering except to persons whom it reasonably believes to be QIBs in transactions pursuant to Rule 144A under the Securities Act (“Rule 144A”) and in connection with each such sale, it has taken
or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in reliance on Rule 144A. 

  
 3 

 (c) Each Initial Purchaser acknowledges and agrees that the Company and, for purposes of the
opinions to be delivered to the Initial Purchasers pursuant to Sections 6(f), 6(g), 6(h) and 6(i), counsel for the Company, regulatory counsel for the Company and counsel for the Initial Purchasers, respectively,
may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by the Initial Purchasers with their agreements, contained in paragraph (b) above, and each Initial Purchaser hereby consents to such
reliance. 
 (d) The Company acknowledges and agrees that the Initial Purchasers may offer and sell Securities to or through any affiliate of
an Initial Purchaser and that any such affiliate may offer and sell Securities purchased by it to or through any Initial Purchaser; provided that such offers and sales shall be made in accordance with the terms of this Agreement. 

(e) Payment for the Securities shall be made by wire transfer in immediately available funds to the account specified by the Company to the
Representatives, in the case of the Underwritten Securities, at the offices of Latham & Watkins LLP, 885 Third Avenue, New York, New York 10022 at 10:00 a.m. New York City time on November 21, 2018, or at such other time or place on
the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing or, in the case of the Option Securities, on the date and at the time and place specified by the
Representatives in the written notice of the Initial Purchasers’ election to purchase such Option Securities. The time and date of such payment for the Underwritten Securities is referred to herein as the “Closing Date” and the
time and date for such payment for the Option Securities, if other than the Closing Date, is herein referred to as the “Additional Closing Date.” 

Payment for the Securities to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against
delivery to the nominee of The Depository Trust Company (“DTC”), for the respective accounts of the several Initial Purchasers of the Securities to be purchased on such date of one or more global notes representing the Securities
(collectively, the “Global Note”). The Global Note will be made available for inspection by the Representatives at the office of J.P. Morgan Securities LLC set forth above not later than 1:00 p.m., New York City time, on the
business day prior to the Closing Date or the Additional Closing Date, as the case may be. 
 (f) The Company acknowledges and agrees that
each Initial Purchaser is acting solely in the capacity of an arm’s-length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection
with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representatives nor any other Initial Purchaser is advising the Company or any
other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and
appraisal of the transactions contemplated hereby, and the Initial Purchasers shall have no responsibility or liability to the Company with respect thereto. Any review by the Representatives or any Initial Purchaser of the Company, the transactions
contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Initial Purchaser and shall not be on behalf of the Company or any other person.

to each Initial Purchaser that: 
 (a) Preliminary Offering Memorandum. The Preliminary Offering Memorandum, as of its date, did not
contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Company makes
no representation and warranty with respect to any statements or omissions made in reliance upon and in conformity with information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the

Communications. The Company (including its agents and representatives, other than the Initial Purchasers in their capacity as such) has not prepared, made, used, authorized, approved or referred to and will not prepare, make, use, authorize,
approve or refer to any “written communication” (as defined in Rule 405 under the Securities Act) that constitutes an offer to sell or solicitation of an offer to buy the Securities or the Private Securities (each such communication by the
Company or its agents and representatives (other than a communication referred to in clauses (i), (ii) and (iii) below) an “Issuer Written Communication”) other than, with respect to the Securities, (i) the Preliminary
Offering Memorandum; (ii) the Offering Memorandum; (iii) the documents listed on Annex A hereto, including a term sheet substantially in the form of Annex B hereto, which constitute part of the Time of Sale Information; and
(iv) each electronic road show and any other written communications, in each case used in accordance with Section 4(c). Each such Issuer Written Communication does not conflict with the information contained in the
Time of Sale Information, and when taken together with the Time of Sale Information, did not, and at the Closing Date and as of the Additional Closing Date, as the case may be, will not, contain any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that the Company makes no representation and warranty with respect to any
statements or omissions made in each such Issuer Written Communication in reliance upon and in conformity with information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives
expressly for use in such Issuer Written Communication, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the information described as such in Section 7(b) hereof.

  
 5 

 (d) Offering Memorandum. As of the date of the Offering Memorandum and as of the
Closing Date and as of the Additional Closing Date, as the case may be, the Offering Memorandum does not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading; provided that the Company makes no representation and warranty with respect to any statements or omissions made in reliance upon and in conformity with information
relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Offering Memorandum, it being understood and agreed that the only such information furnished by any
Initial Purchaser consists of the information described as such in Section 7(b) hereof. 
 (e) Incorporated
Documents. The documents incorporated by reference in the Offering Memorandum or the Time of Sale Information, when they were filed with the Commission, or as subsequently amended prior to the Time of Sale, conformed or will conform, as the case
may be, in all material respects to the requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) and such documents did not and
will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(f) Financial Statements. The financial statements and the related notes thereto of the Company and its consolidated subsidiaries

throughout the periods covered thereby; and the other financial information included or incorporated by reference in each of the Time of Sale Information and the Offering Memorandum has been derived from the accounting records of the Company and its
consolidated subsidiaries and presents fairly the information shown thereby. 
 (g) No Material Adverse Change. Since the date of the
most recent consolidated financial statements of the Company included or incorporated by reference in each of the Time of Sale Information and the Offering Memorandum, (i) there has not been any material change in the capital stock, short-term
debt or long-term debt of the Company or any of its subsidiaries, or any dividend or distribution of any kind declared, set aside for payment, paid or made by the Company on any class of capital stock, or any material adverse change, or any
development involving a prospective material adverse change, in or affecting the business, earnings or results of operations of the Company and its subsidiaries, taken as a whole; (ii) neither the Company nor any of its subsidiaries has entered

of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act. 
 (tt)
Securities Law Exemptions. Assuming the accuracy of the representations and warranties of the Initial Purchasers contained in Section 2(b) hereof and subject to their compliance with their agreements set forth
therein, it is not necessary, in connection with the issuance and sale of the Securities to the Initial Purchasers and the offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by this Agreement, the Time
of Sale Information and the Offering Memorandum, to register the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended, including the rules and regulations of the Commission promulgated
thereunder (the “Trust Indenture Act”). It is not necessary, in connection with the issuance and sale of the Private Securities, to register the Private Securities or the Private Placement under the Securities Act or the securities
laws of any state having jurisdiction with respect thereto, or to qualify the Indenture under the Trust Indenture Act. 
 (uu) No
Stabilization. Except, for the avoidance of doubt, with respect to the forward stock purchase transactions described in the Time of Sale Information and the Offering Memorandum, the Company has not taken, directly or indirectly, any action
designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities or the Private Securities. 

(vv) Statistical and Market Data. The statistical and market-related data and forward-looking statements included or incorporated by
reference in the Time of Sale Information and the Offering Memorandum are based on or derived from sources that the Company believes to be reliable and accurate in all material respects or represent the Company’s good faith estimates that are
made on the basis of the data derived from such sources.

effect to the application of the net proceeds of the offering of the Securities and the Private Placement described under “Use of proceeds” in the Offering Memorandum), will be, Solvent. As used herein, the term “Solvent”
means, with respect to any person on a particular date, that on such date (i) the fair market value of the assets of such person is greater than the total amount of liabilities (including contingent liabilities) of such person, (ii) the
present fair salable value of the assets of such person is greater than the amount that will be required to pay the probable liabilities of such person on its debts as they become absolute and matured, (iii) such person is able to realize upon
its assets and pay its debts and other liabilities, including contingent obligations, as they mature and (iv) such person does not have unreasonably small capital; provided, that in each case, clauses (i) through (iv) hereof include such
person’s rights to contribution.

“nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act.

 (c) Additional Written Communications. Before
making, preparing, using, authorizing, approving or referring to any Issuer Written Communication, the Company will furnish to the Representatives and counsel for the Initial Purchasers a copy of such written communication for review and will not
make, prepare, use, authorize, approve or refer to any such written communication to which the Representatives reasonably object. 
 (d)
Notice to the Representatives. The Company will advise the Representatives promptly, and confirm such advice in writing, (i) of the issuance by any governmental or regulatory authority of any order preventing or suspending the use of any
of the Time of Sale Information, any Issuer Written Communication or the Offering Memorandum or the initiation or threatening of any proceeding for that purpose; (ii) of the occurrence or development of any event at any time prior to the
completion of the initial offering of the Securities as a result of 

  
 18 

 
which any of the Time of Sale Information, any Issuer Written Communication or the Offering Memorandum as then amended or supplemented would include any untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when such Time of Sale Information, Issuer Written Communication or the Offering Memorandum is delivered to a purchaser, not

such qualification of the Securities and, if any such order is issued, will use its reasonable best efforts to obtain as soon as possible the withdrawal thereof. 

(e) Ongoing Compliance of the Offering Memorandum and Time of Sale Information. (1) If at any time prior to the completion of the
initial offering of the Securities (i) any event or development shall occur or condition shall exist as a result of which the Offering Memorandum as then amended or supplemented would include any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Offering Memorandum is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the
Offering Memorandum to comply with law, the Company will immediately notify the Initial Purchasers thereof and forthwith prepare and, subject to paragraph (b) above, furnish to the Initial Purchasers such amendments or supplements to the
Offering Memorandum (or any document to be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in the Offering Memorandum as so amended or supplemented (or including such document to be
incorporated by reference therein) will not, in the light of the circumstances existing when the Offering Memorandum is delivered to a purchaser, be misleading or so that the Offering Memorandum will comply with law and (2) if at any time prior

with law, the Company will immediately notify the Initial Purchasers thereof and forthwith prepare and, subject to paragraph (b) above, furnish to the Initial Purchasers such amendments or supplements to any of the Time of Sale Information (or
any document to be filed with the Commission and incorporated by reference therein) as may be necessary so that the statements in any of the Time of Sale Information as so amended or supplemented will not, in light of the circumstances under which
they were made, be misleading. 
 (f) Blue Sky Compliance. The Company will qualify the Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for the offering and resale of the Securities; provided that the Company

in any such jurisdiction; or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or publicly disclose
the intention to make any offer, sale, pledge, disposition or filing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other
securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Representatives, other than

convertible notes may affect the value of the notes and our common stock,” and a registered offering of up to the aggregate number of shares of our common stock underlying the forward stock purchase transactions in connection with the
Company’s request that any forward counterparty modify the settlement terms of its forward stock purchase transaction to provide for a payment in cash in lieu of the delivery of the applicable number of shares of Common Stock of the Company to
the Company to settle a portion of the Company’s forward stock purchase transaction as described in “Risk factors—Risks related to this offering and the notes—Any modifications of the existing forward stock purchase
transactions may affect the value of the notes and our common stock and may result in unexpected market activity in the notes and/or our common stock”; (F) the Private Placement; or (G) the issuance of shares of Common Stock (or
options, warrants or convertible securities in respect of Common Stock) in connection with any merger or acquisition of securities, businesses, property or other assets, joint ventures, strategic alliances, technology development or equipment
manufacturing arrangements or debt financing, provided that the aggregate number of shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock (on an as-converted
or as-exercised basis, as the case may be) that the Company may sell or issue or agree to sell or issue pursuant to this clause (G) shall not exceed 5% of the total number of shares of the Company’s
Common Stock issued and outstanding immediately following the completion of the transactions contemplated herein; provided, further, that any recipients of such Common Stock or securities convertible into or exchangeable for shares of
Common Stock pursuant to this clause (G) shall execute a lock-up agreement substantially in the form of Exhibit A hereto.

 20 

 (i) No Stabilization. Except, for the avoidance of doubt, with respect to the forward
stock purchase transactions described in the Time of Sale Information and the Offering Memorandum, the Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization
or manipulation of the price of the Securities or the Private Securities and will not take any action prohibited by Regulation M under the Exchange Act in connection with the distribution of the Securities contemplated hereby. 

(j) Underlying Securities. The Company will reserve and keep available at all times, free of
pre-emptive rights, a number of shares of Common Stock equal to the Maximum Number of Underlying Securities. The Company will use its best efforts to cause and maintain the listing of such shares of Common
Stock on The NASDAQ Global Select Market (the “Exchange”) for so long as any shares of Common Stock are listed on the Exchange, and will use its best efforts to cause and maintain the listing of such shares of Common Stock on any
other stock exchange for so long as all the other shares of Common Stock are listed on such other stock exchange. 
 (k) Supplying
Information. While the Securities remain outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company will, during any period in which the Company is not subject to and
in compliance with Section 13 or 15(d) of the Exchange Act, furnish to holders of the Securities, prospective purchasers of the Securities designated by such holders and securities analysts, in each case upon request, the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 (l) DTC. The Company will assist the Initial Purchasers in
arranging for the Securities to be eligible for clearance and settlement through DTC.

period from the Closing Date until one year after the Closing Date or the Additional Closing Date, if applicable, the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the
Securities that have been acquired by any of them, except for Securities purchased by the Company or any of its affiliates and resold in a transaction registered under the Securities Act. 

(n) No Integration. Neither the Company nor any of its affiliates (as defined in Rule 501(b) of Regulation D) will, directly or through
any agent, sell, offer for sale, solicit offers to buy or otherwise negotiate in respect of, any security (as defined in the Securities Act), including the Private Securities, that is or will be integrated with the sale of the Securities in a manner
that would require registration of the Securities under the Securities Act. 
 (o) No General Solicitation. None of the Company or any
of its affiliates (as defined in Rule 501(b) of Regulation D) or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no covenant is given) will solicit offers for, or offer or sell, the Securities or
Private Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.

  
 21 

 5. Certain Agreements of the Initial Purchasers. Each Initial Purchaser hereby
represents and agrees that it has not and will not use, authorize use of, refer to, or participate in the planning for use of, any written communication that constitutes an offer to sell or the solicitation of an offer to buy the Securities other
than (i) the Preliminary Offering Memorandum and the Offering Memorandum; (ii) a written communication that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including
through incorporation by reference) in the Preliminary Offering Memorandum or the Offering Memorandum; (iii) any written communication listed on Annex A or prepared pursuant to Section 4(c) above (including any

(ii) On the date of this Agreement and on the Closing Date or the Additional Closing Date, as the case may be, the Company
shall have furnished to the Representatives a certificate, dated the respective dates of delivery thereof and addressed to the Initial Purchasers, of its chief financial officer with respect to certain financial data contained in the Time of Sale

 7. Indemnification
and Contribution. 
 (a) Indemnification of the Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial
Purchaser, its directors and officers, and each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Initial Purchaser
within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and 

  
 24 

 
liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement
or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication, any road show as defined in Rule 433(h) under the Securities Act (a
“road show”) (when considered together with the Time of Sale Information), or the Offering Memorandum (or any amendment or supplement thereto), or caused by any omission or alleged omission to state therein a material fact necessary
in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein, it being understood and agreed that
the only such information furnished by any Initial Purchaser consists of the information described as such in subsection (b) below. 

(b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the
Company, its directors, its officers and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in
paragraph (a) above, but only with respect to any losses, claims, damages or liabilities caused by any untrue statement or omission or alleged untrue statement or omission made with reference to information relating to such Initial Purchaser
furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information (including any of the other Time of Sale Information that
has subsequently been amended), any Issuer Written Communication, any road show or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by any Initial Purchaser
consists of the following information in the Offering Memorandum furnished on behalf of each Initial Purchaser: the information contained in the fourth and fifth sentences of the third paragraph under the caption “Plan of distribution—New
issue of notes” and the first paragraph under the caption “Plan of distribution—Price stabilization and short positions; repurchase of common shares.” 

(c) Notice and Procedures. If any proceeding (including any governmental investigation) shall be instituted involving any person in
respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the
“Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has
been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have
to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person
shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the
fees and disbursements of 

  
 25 

 
such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the retention of such counsel; (ii) the Indemnifying Person has failed within a reasonable time
to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the
Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in respect of the legal expenses of any Indemnified Person in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Initial Purchasers, their directors and officers, and all persons, if any, who control any
Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Initial Purchaser within the meaning of Rule 405 under the Securities Act, and (ii) the
fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of either such Section, and that all such fees and
expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser and any control persons or affiliates of such Initial Purchaser shall be designated in writing by the Representatives and any such separate firm for
the Company, its directors, its officers and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but
if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable
for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have
reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such
Indemnified Person from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

 (d) Contribution. If the indemnification provided for in paragraphs (a) or (b) above is unavailable to an Indemnified Person
or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such 

  
 26 

 
proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other, from the offering of the Securities or
(ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on
the one hand, and the Initial Purchasers, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits
received by the Company, on the one hand, and the Initial Purchasers, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and
the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company, on the one hand, and the
Initial Purchasers, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied
by the Company or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute
pursuant to this Section 7 are several in proportion to the respective aggregate principal amount of Securities they have purchased hereunder, and not joint. 

(e) Limitation on Liability. The Company and the Initial Purchasers agree that it would not be just or equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an
Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such
Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to
their respective purchase obligations hereunder and not joint. 
 (f) Non-Exclusive Remedies.
The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. 

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. 

  
 27 

 9. Termination. This Agreement may be terminated in the absolute discretion of the
Representatives, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Securities, prior to the Additional Closing Date (i) trading generally shall have
been suspended or materially limited on or by any of the New York Stock Exchange or The NASDAQ Global Select Market; (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there
shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, singly or together with any other event specified in this clause (iv), in the judgment of the Representatives, is
material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by
this Agreement, the Time of Sale Information and the Offering Memorandum. 
 10. Defaulting Initial Purchaser. 

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Initial Purchaser defaults on its obligation to purchase
the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to
the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such
Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such
terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date or the
Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the
Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement,
the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases
Securities that a defaulting Initial Purchaser agreed but failed to purchase. 
 (b) If, after giving effect to any arrangements for the
purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal
amount of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be does not exceed one-eleventh of the aggregate principal amount of Securities to be purchased
on such date, then each non-defaulting Initial Purchaser shall be obligated severally to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder on such date plus
such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase on such date) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for
which such arrangements have not been made. 

  
 28 

 (c) If, after giving effect to any arrangements for the purchase of the Securities of a
defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of Securities that remain
unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of Securities to be purchased on such date then this Agreement or,
with respect to any Additional Closing Date, the obligation of the Initial Purchasers to purchase Securities on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the
non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will
continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect. 

(d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any non-defaulting Initial Purchaser for damages caused by its default. 
 11. Payment of
Expenses. 
 (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated,
the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the
Securities and any transfer, stamp, documentary and similar taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written
Communication and the Offering Memorandum (including any amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the
Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions
as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating
the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the
Securities for book-entry transfer by DTC; (ix) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Securities, including,
without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the
road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants; provided that the Underwriters shall pay for one-half of the expense of any consultants engaged in connection with the road show presentations as described in this clause (ix); (x) all expenses and application fees related to the listing of the Underlying
Securities on the Exchange; (xi) all expenses incurred in connection with the offer and sale of the Private Securities in the Private Placement; and (xii) all other costs and expenses incident to the performance of the Company of its
obligations hereunder for which provision is not otherwise made in this Section. 

  
 29 

 (b) If (i) this Agreement is terminated pursuant to Section 9
hereof; (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers; or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company
agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and disbursements of their counsel) reasonably incurred by the
Initial Purchasers in connection with this Agreement and the offering contemplated hereby. 
 12. Persons Entitled to Benefit of
Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 7 hereof.
Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial
Purchaser shall be deemed to be a successor merely by reason of such purchase. 
 13. Survival. The respective indemnities, rights of
contribution, representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company or the Initial Purchasers pursuant to this Agreement or any certificate delivered
pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Initial
Purchasers. 
 14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term
“affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the
term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act. 
 15. Compliance with USA Patriot Act. In
accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that
identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective

Company and constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms. 

5. The Securities have been duly authorized and executed by or on behalf of the Company, and, when issued and authenticated on
behalf of the Trustee in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers today in accordance with the terms of the Purchase Agreement, will constitute valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, and will be entitled to the benefits of the Indenture. 
 6.
The statements in the Time of Sale Information and the Offering Memorandum, insofar as such statements purport to summarize the terms of the Company’s common stock, under the heading “Description of common stock,” are accurate in all
material respects. 
 7. The statements in the Time of Sale Information and the Offering Memorandum under the heading

9. The shares of common stock issuable upon conversion of the Securities in accordance with the terms of the Indenture have
been duly authorized and reserved for issuance upon such conversion by all necessary corporate action on the part of the Company and such shares, when issued upon such conversion in accordance with the terms of the Indenture and the Securities, will
be validly issued, fully paid and non-assessable. The issuance of such shares of common stock upon conversion of the Securities is not subject to preemptive or similar subscription rights arising under the
DGCL or the Third Amended and Restated Certificate of Incorporation or Amended and Restated By-Laws of the Company. 

 10. To our knowledge, no consent or authorization of, approval by, notice to
or filing with any United States Federal, New York State or (insofar as the DGCL is concerned) Delaware governmental authority is required under United States Federal or New York State statute, rule or regulation or the DGCL to be obtained or made
on or prior to the date hereof by the Company for the execution and delivery by the Company of the Purchase Agreement, the Indenture and the Securities or the issuance and sale today by the Company of the Securities in accordance with the terms of
the Purchase Agreement, except for any consents, authorizations, approvals, notices and filings that have been obtained or made and are in full force and effect and those consents, authorizations, approvals, notices and filings that, individually or
in the aggregate, if not made, obtained or done would not to our knowledge have a Material Adverse Effect; provided that we express no opinion in this paragraph 10 with respect to United States Federal or state securities laws. 

11. The execution and delivery by the Company of the Purchase Agreement and the Indenture did not, the execution and delivery
by the Company of the Indenture will not, and the issuance and sale today by the Company of the Securities in accordance with the terms of the Indenture and the Purchase Agreement will not violate (a) the Third Amended and Restated

the DGCL, (c) any existing judgment, order or decree known to us of any United States Federal, New York State or (insofar as the DGCL is concerned) Delaware court or other governmental authority known by us to be binding upon the Company

each of the Time of Sale Information and the Offering Memorandum, the statements of United States Federal income tax law under the heading “Certain U.S. federal income tax considerations” in the Time of Sale Information and the Offering
Memorandum, as they relate to the Securities, are accurate in all material respects. 
 14. It is not necessary, in
connection with the offer, sale and delivery of the Securities by the Company to the Initial Purchasers and the initial resale of the Securities by the Initial Purchasers to the subsequent purchasers, in accordance with the Purchase Agreement and in
the manner contemplated by the Purchase Agreement and the Offering Memorandum, to register the Securities under the U.S. Securities Act of 1933, as amended, or to qualify the Indenture under the Trust Indenture Act of 1939, as amended. We express no
opinion as to any subsequent resale of any Security.

On the basis of the foregoing, we advise you that no facts have come to our attention that have caused us to believe that (a) the
Time of Sale Information, as of 6:00 p.m. New York City time on November 16, 2018, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; or (b) the Offering Memorandum, as of the date of the Offering Memorandum and as of the date and time of the delivery of this letter, contained or contains any untrue statement of
a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that in each case we express no belief as to
(1) the financial statements, the related notes and schedules, and other financial and accounting data or information contained in or omitted from the Time of Sale Information or the Offering Memorandum or (2) the report of

FORM OF OPINION OF GENERAL COUNSEL OF THE COMPANY 

1. Each of AC BidCo LLC, Gogo LLC, Gogo Business Aviation LLC, Gogo Intermediate Holdings LLC and Gogo International Holdings LLC (the “Covered
Subsidiaries”) is validly existing and in good standing under the laws of the State of Delaware. Each of the Covered Subsidiaries has the limited liability power and authority to conduct its business as described in the Time of Sale
Information and the Offering Memorandum. 

 Annex E 

FORM OF OPINION OF REGULATORY COUNSEL FOR THE COMPANY 

(a) The Company’s subsidiary AC BidCo LLC holds the 800 MHz Commercial Aviation Air-Ground
Radiotelephone Service authorizations and the Earth Stations Aboard Aircraft authorization, and Gogo Business Aviation LLC, an additional subsidiary of the Company, holds the International Section 214 authorization, each identified on
Schedule 3 hereto (the “FCC Licenses”). Except as set forth on Schedule 3 hereto or as disclosed in the Preliminary Offering Memorandum or the Offering Memorandum, the FCC Licenses are in full force and
effect, as defined below, until the expiration dates specified in Schedule 3. AC BidCo or other subsidiaries of the Company hold the experimental authorization, two fixed satellite earth station licenses, aircraft licenses and microwave
industrial/business pool authorizations identified on Schedule 4 hereto (collectively, the “Other Licenses”). Except as set forth on Schedule 4 hereto or as disclosed in the Preliminary Offering Memorandum or the Offering
Memorandum, the Other Licenses are in full force and effect, as defined below, until the expiration dates specified in Schedule 4. 

(b) The FCC Licenses are not subject to any conditions or requirements other than conditions or requirements that appear on the face of the FCC
Licenses or that are set forth in the FCC’s rules, regulations, orders and policies that are applicable to such licenses. 
 (c) One of
the FCC Licenses, WQFX728, includes a construction requirement (a showing of “substantial service” pursuant to 47 C.F.R. § 22.873) which was required to be made by October 31, 2011. AC BidCo filed a substantial service showing on
December 11, 2008, which was accepted by the FCC on April 6, 2009. 
 (d) Based upon our FCC Public Files Examination, no judgment,
decree, order or notice has been issued by the FCC which permits, or after notice or lapse of time or both, would permit, revocation, nonrenewal or termination of the FCC Licenses or the Other Licenses prior to the expiration date thereof, or which
results or would result in any other material impairment of any rights thereunder, except as set forth in Schedule 4 hereto. Based upon our FCC Public Files Examination, no notice of violation or adverse order, or, to our knowledge, any
unresolved objection, petition to deny or opposition has been issued by or filed with the FCC in connection with the FCC Licenses or the Other Licenses. 

(e) No consent, approval or authorization by or filing with the FCC is required to be obtained or made by the Company or its subsidiaries
listed on Schedule 3 or Schedule 4 hereto as holding the FCC Licenses or the Other Licenses (the “FCC Subsidiaries”) in connection with the execution, delivery and performance by the Company of the Agreement and the Notes
Documents. The execution and delivery of the Agreement and the Notes Documents by the Company and the performance of the Agreement and the Notes Documents by the Company do not violate any applicable provision of the Communications Act or the FCC
Rules, the FCC Licenses or the Other Licenses or to our knowledge any judgment, order or decree of the FCC to which the Company or any of the FCC Subsidiaries is a party. 

 (f) Except as set forth on Schedule 5 hereto, the statements incorporated into the
Preliminary Offering Memorandum and the Offering Memorandum from the Form 10-K discussing regulation by the FCC under the captions “Risk Factors—Risks Related to Our Technology and Intellectual
Property and Regulation” and “Business—Licenses and Regulation,” insofar as such statements purport to summarize applicable provisions of the Communications Act, the FCC Rules or the FCC Licenses or the Other Licenses, are
accurate in all material respects.

Stock (including without limitation, Common Stock or such other securities which are beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon

registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The foregoing sentence shall not apply to (a) transactions relating to shares of Common Stock or other securities

Company (A) to satisfy tax withholding obligations in connection with the exercise of options to purchase Common Stock or (B) in connection with the rights of the Company to redeem or cause the disposition of shares of Common Stock in
order to ensure the Company’s compliance with the Communications Act of 1934, as amended; (h) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of
shares of Common Stock; provided that such plan does not provide for the transfer of Common Stock during the restricted period and no public announcement or filing under the Exchange Act regarding the establishment of such plan shall be
required of or voluntarily made by or on behalf of the undersigned or the Company during the restricted period; (i) transfers of shares of Common Stock pursuant to a trading plan pursuant to Rule 10b5-1
