CREDIT SUISSE SECURITIES (USA) LLC 
 MORGAN STANLEY & CO. LLC 

WELLS FARGO SECURITIES, LLC, 
     As Representatives of the Several Purchasers, 

        c/o Credit Suisse Securities (USA) LLC (“Credit Suisse”), 

            Eleven Madison Avenue, 
                 New York, N.Y. 10010-3629 
 Dear Sirs and Mesdames: 
 tw telecom holdings inc., a Delaware corporation
(the “Issuer”), proposes to issue and sell to the several initial purchasers named in Schedule A to the Purchase Agreement (collectively, the “Initial Purchasers”), upon the terms set forth in a purchase
agreement dated as of August 12, 2013 (the “Purchase Agreement”), $350,000,000 aggregate principal amount of its 6.375% Senior Notes due 2023 (the “Initial Securities”) to be unconditionally guaranteed (the
“Guarantees”) by tw telecom inc., the parent of the Company (“TWT Inc.”), and certain subsidiaries of TWT Inc. listed in Schedules C-1 and C-2 to the Purchase Agreement (together with TWT Inc.,
the “Guarantors”, and the Guarantors together with the Issuer, the “Company”). The Initial Securities will be issued pursuant to an Indenture dated as of August 26, 2013 (the “Indenture”),
among the Issuer, the Guarantors and Wells Fargo Bank, National Association (the “Trustee”). As an inducement to the Initial Purchasers, the Issuer and the Guarantors agree with the Initial Purchasers, for the benefit of the holders
of the Initial Securities (including the Initial Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively the “Holders”), as follows: 

1. Registered Exchange Offer. The Company shall, at its own cost, prepare and, not later than 180 days after (or if the
180th day is not a business day, the first business day thereafter) the date of original issue of the Initial Securities (the “Issue Date”), file with the Securities and Exchange Commission (the “Commission”) a
registration statement (the “Exchange Offer Registration Statement”) on an appropriate form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer (the
“Registered Exchange Offer”) to the Holders of Transfer Restricted Securities (as defined in Section 6 hereof), who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer,
to issue and deliver to such Holders, in exchange for the Initial Securities, a like aggregate principal amount of debt securities (the “Exchange Securities”) of the Company issued under the Indenture and identical in all material
respects to the Initial Securities (except for the transfer restrictions relating to the Initial Securities and the provisions relating to the matters described in Section 6 hereof) that would be registered under the Securities Act. The Company
shall use its reasonable best efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act within 270 days (or if the 270th day is not a business day, the first business day thereafter) after the Issue
Date of the Initial Securities and shall keep the Registered Exchange Offer open for not less than 20 business days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such
period being called the “Exchange Offer Registration Period”). 

 If the Company effects the Registered Exchange Offer, the Company will be entitled to close
the Registered Exchange Offer 20 business days after the commencement thereof provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer. 

Following the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the
Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as defined in Section 6 hereof) electing to exchange the Initial Securities for Exchange Securities
(assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business and has no arrangements with any person to participate in
the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and after their receipt without any limitations or
restrictions under the Securities Act and without material restrictions under the securities laws of the several states of the United States. 
 The Company acknowledges that, pursuant to current interpretations by the Commission’s staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom,
(i) each Holder which is a broker-dealer electing to exchange Securities, acquired for its own account as a result of market making activities or other trading activities, for Exchange Securities (an “Exchanging Dealer”), is
required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section,
and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities received by such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an
Initial Purchaser that elects to sell Exchange Securities acquired in exchange for Securities constituting any portion of an unsold allotment is required to deliver a prospectus containing the information required by Items 507 or 508 of Regulation
S-K under the Securities Act, as applicable, in connection with such sale. 
 The Company shall use its reasonable best efforts
to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of
the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Securities; provided, however, that (i) in the case where such prospectus and any amendment or supplement thereto must
be delivered by an Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange Securities held by them (unless such period is
extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment or supplement thereto, available to any broker-dealer for use in connection with any resale of any Exchange Securities for a period
of not less than 90 days after the consummation of the Registered Exchange Offer. 
 If, upon consummation of the Registered
Exchange Offer, any Initial Purchaser holds Initial Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and
deliver to such Initial Purchaser upon the written request of such Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held by such Initial Purchaser, a like principal amount of debt securities of the
Company issued under the Indenture and identical in all material respects (including the existence of restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding provisions
relating to the matters described in Section 6 hereof) to the Initial Securities (the “Private Exchange Securities”). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively
called the “Securities”. 
 In connection with the Registered Exchange Offer, the Company shall: 

(a) mail to each Holder a copy of the prospectus forming part of the Exchange Offer Registration Statement, together
with an appropriate letter of transmittal and related documents; 

  
 2 

 (b) keep the Registered Exchange Offer open for not less than 20
business days (or longer, if required by applicable law) after the date notice thereof is mailed to the Holders; 

(c) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of
Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee; 
 (d) permit
Holders to withdraw tendered Securities at any time prior to the close of business, New York time, on the last business day on which the Registered Exchange Offer shall remain open; and 

(e) otherwise comply with all applicable laws. 

As soon as reasonably practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the
Company shall: 
 (x) accept for exchange all the Securities validly tendered and not withdrawn pursuant to
the Registered Exchange Offer and the Private Exchange; 
 (y) deliver to the Trustee for cancellation all
the Initial Securities so accepted for exchange; and 
 (z) cause the Trustee to authenticate and deliver
promptly to each Holder of the Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for exchange. 

The Indenture will provide that the Exchange Securities will not be subject to the transfer restrictions set forth in the Indenture and
that all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one another on any matter. 

Interest on each Exchange Security and Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private
Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if no interest has been paid on the Initial Securities, from the date of original issue of the Initial
Securities. 
 Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at
the time of the consummation of the Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any
person to participate in the distribution of the Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or
if it is an affiliate, such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend
to engage in, the distribution of the Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. 
 Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment thereto and any prospectus forming part thereof and any
supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto does not, when it becomes effective, contain an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any prospectus forming part of any Exchange Offer Registration Statement,
and any supplement to such prospectus, does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

 2. Shelf Registration. If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within 300
days of the Issue Date, (iii) any Initial Purchaser so requests with respect to the Initial Securities (or the Private Exchange Securities) not eligible to be exchanged for Exchange Securities in the Registered Exchange Offer and held by it
following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that
participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange, the Company shall take the following actions: 

(a) The Company shall, at its cost, as promptly as practicable (but in no event more than 60 days after so required
or requested pursuant to this Section 2) file with the Commission and thereafter shall use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically upon filing) a registration statement (the
“Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer
Restricted Securities (as defined in Section 6 hereof) by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the
“Shelf Registration”); provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be
bound by all the provisions of this Agreement applicable to such Holder. 
 (b) The Company shall use its
reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such
longer period if extended pursuant to Section 3(j) below) from the Issue Date or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or
(ii) the earliest date that is no less than two years after the Issue Date and on which all such Securities (except for Securities held by an affiliate of the Company) are no longer subject to any restrictions on transfer under the Securities
Act, including those pursuant to Rule 144. The Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result
in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless such action is required by applicable law. 
 (c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement
thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and
(ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not
misleading. 
 (d) Notwithstanding the foregoing provisions of this Section 2, if TWT Inc. furnishes to
each Holder a certificate signed by TWT Inc.’s chief executive officer stating that in the good faith judgment of TWT Inc.’s Board of Directors it would be materially detrimental to TWT Inc. and its stockholders for a Shelf Registration
Statement to be filed, become effective, or remain effective because such action would (i) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving TWT Inc.; (ii) require
premature disclosure of material information that TWT Inc. has a bona fide business purpose for preserving as confidential; or (iii) render TWT Inc. unable to comply with requirements under the Securities

  
 4 

 
Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), then the Company will have the right to defer taking action with respect to such filing, and any time
periods with respect to the filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than 120 days after the filing would otherwise be required; provided, however, that the Company may not invoke this right
more than once; and provided further that neither TWT Inc. nor the Company may register any securities for the its account or that of any stockholder during such 120 day period other than (x) a registration relating to the sale of
securities to employees of TWT Inc. or a subsidiary thereof pursuant to a stock option, stock purchase, or similar plan; (y) a registration relating to a Commission Rule 145 transaction; or (z) a registration on any form that does not
include substantially the same information as would be required to be included in a Shelf Registration Statement. 

3. Registration Procedures. In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent
applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 
 (a) The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration Statement and each amendment thereof and each supplement,
if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the Registered Exchange Offer or the Shelf Registration
Statement, the Company shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose; (ii) include the information set forth in Annex A hereto on
the cover, in Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section and in Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of the
Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer; (iii) if requested by an Initial Purchaser, include the information
required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming a part of the Exchange Offer Registration Statement; (iv) include within the prospectus contained in the Exchange Offer
Registration Statement a section entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect
to the potential “underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act of Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a
“Participating Broker-Dealer”), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial Purchasers based upon advice
of counsel (which may be in-house counsel), represent the prevailing views of the staff of the Commission; and (v) in the case of a Shelf Registration Statement, include in the prospectus included in the Shelf Registration Statement (or, if
permitted by Commission Rule 430B(b), in a prospectus supplement that becomes a part thereof pursuant to Commission Rule 430B(f)) that is delivered to any Holder pursuant to Section 3(d) and (f), the names of the Holders, who
propose to sell Securities pursuant to the Shelf Registration Statement, as selling securityholders. 

(b) The Company shall give written notice to the Initial Purchasers, the Holders of the Securities and any
Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an
instruction to suspend the use of the prospectus until the requisite changes have been made): 
 (i) when
the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; 

(ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus
included therein or for additional information; 

  
 5 

 (iii) of the issuance by the Commission of any stop order suspending
the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, of the issuance by the Commission of a notification of objection to the use of the form on which the Registration Statement has been filed, and of
the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission Rule 405. 
 (iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose; and 
 (v) of the happening of any event that requires the
Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein
or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading. 
 (c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the Registration Statement. 

(d) If not otherwise available on the Commission’s EDGAR system or any successor system, upon the written
request of any Holder, the Company shall furnish to each Holder of Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment or
supplement thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference). The Company shall not, without the prior consent of the Initial
Purchasers, make any offer relating to the Securities that would constitute a “free writing prospectus,” as defined in Commission Rule 405. 
 (e) If not otherwise available on the Commission’s EDGAR system or any successor system, upon written request, the Company shall deliver to each Exchanging Dealer and each Initial Purchaser, and
to any other Holder who so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if any Initial Purchaser or any such
Holder requests, all exhibits thereto (including those incorporated by reference). 
 (f) The Company shall,
during the Shelf Registration Period, deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf
Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of
the selling Holders of the Securities in connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 

(g) The Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any Participating Broker-Dealer and
such other persons required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such
persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Initial Purchaser, if necessary, any Participating Broker-Dealer and such
other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement thereto, included in such Exchange
Offer Registration Statement. 

  
 6 

 (h) Prior to any public offering of the Securities, pursuant to any
Registration Statement, the Company shall register or qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale
under the securities or “blue sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such
jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take
any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 
 (i) The Company shall cooperate with the Holders of the Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement.

 (j) Upon the occurrence of any event contemplated by paragraphs (ii) through (v) of
Section 3(b) above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the
related prospectus and any other required document so that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchasers, the Holders of the Securities and any known
Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers, the
Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration
Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders of the Securities and any known
Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j). During the period during which the Company is required to maintain an effective Shelf Registration Statement pursuant to this
Agreement, the Company will prior to the three-year expiration of that Shelf Registration Statement file, and use its reasonable best efforts to cause to be declared effective (unless it becomes effective
automatically upon filing) within a period that avoids any interruption in the ability of Holders of Securities covered by the expiring Shelf Registration Statement to make registered dispositions, a new registration statement relating to the
Securities, which shall be deemed the “Shelf Registration Statement” for purposes of this Agreement. 

(k) Not later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP
number for the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable trustee with printed certificates for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the
case may be, in a form eligible for deposit with The Depository Trust Company. 
 (l) The Company will
comply with all rules and regulations of the Commission to the extent and so long as they are applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its security holders (or otherwise provide in
accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal
year) beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period. 

  
 7 

 (m) The Company shall cause the Indenture to be qualified under the
Trust Indenture Act of 1939, as amended, in a timely manner and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture,
the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 

(n) The Company may require each Holder of Securities to be sold pursuant to the Shelf Registration Statement to
furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company may exclude from such
registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 
 (o) The Company shall enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as any Holder of the
Securities shall reasonably request in order to facilitate the disposition of the Securities pursuant to any Shelf Registration. 
 (p) In the case of any Shelf Registration, the Company shall (i) make reasonably available for inspection by the Holders of the Securities, any underwriter participating in any disposition
pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Securities or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the
Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders of the Securities or any such underwriter, attorney, accountant or agent
in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that
the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described in Section 4
hereof. 
 (q) In the case of any Shelf Registration, the Company, if requested by any Holder of Securities
covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any, thereof and dated, in the case of the initial
opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include the due incorporation and good standing of the Company and its subsidiaries; the qualification of the
Company and its subsidiaries to transact business as foreign corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution, authentication
and issuance, and the validity and enforceability, of the applicable Securities; the absence of material legal or governmental proceedings involving the Company and its subsidiaries; the absence of governmental approvals required to be obtained in
connection with the Shelf Registration Statement, the offering and sale of the applicable Securities, or any agreement of the type referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any
documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; and (A) as of the date of the opinion and as of the effective date of the Shelf Registration
Statement or most recent post-effective amendment thereto, as the case may be, the absence from such Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference
therein and (B) as of an applicable time identified by such Holders or managing underwriters, the absence from such prospectus taken together with any other documents identified by such Holders or managing underwriters, in the case of (A)
and (B), of an untrue statement of a material fact or the omission 

  
 8 

 
to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any such incorporated documents, in the light of the
circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters
of the applicable Securities and (iii) its independent public accountants to provide to the selling Holders of the applicable Securities and any underwriter therefor a comfort letter in customary form and covering matters of the type
customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72 or any successor
thereto. 
 (r) In the case of the Registered Exchange Offer, if requested by any Initial Purchaser or any
known Participating Broker-Dealer, the Company shall cause (i) its counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set forth in Section 7 of the Purchase Agreement with such
changes as are customary in connection with the preparation of a Registration Statement and (ii) its independent public accountants to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form,
meeting the requirements as to the substance thereof as set forth in Section 7(a) of the Purchase Agreement, with appropriate date changes. 
 (s) If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Securities by Holders to the Company (or to such other Person as directed by the Company)
in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company shall mark, or caused to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for
the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial Securities be marked as paid or otherwise satisfied. 

(t) The Company will use its reasonable best efforts to (a) if the Initial Securities have been rated prior to
the initial sale of such Initial Securities, confirm such ratings will apply to the Securities covered by a Registration Statement, or (b) if the Initial Securities were not previously rated, cause the Securities covered by a Registration
Statement to be rated with the appropriate rating agencies, if so requested by Holders of a majority in aggregate principal amount of Securities covered by such Registration Statement, or by the managing underwriters, if any. 

(u) In the event that any broker-dealer registered under the Exchange Act shall underwrite any Securities or
participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Rules”) of the Financial Industry Regulatory Authority, Inc.
(“FINRA”)) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in complying with the
requirements of such Rules, including by (i) if such Rules, including Rule 2720, shall so require, engaging a “qualified independent underwriter” (as defined in Rule 2720) to participate in the preparation of the Registration
Statement relating to such Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or
sales agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 5 hereof and (iii) providing such
information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 
 (v) The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Securities covered by a Registration Statement contemplated hereby.

 4. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance
of its obligations under Sections 1 through 3 hereof (excluding fees, if any, of counsel for the Initial Purchasers incurred in connection with the Registered Exchange Offer), whether or 

  
 9 

 
not the Registered Exchange Offer or a Shelf Registration is filed or becomes effective, and, in the event of a Shelf Registration, shall bear or reimburse the Holders of the Securities covered
thereby for the reasonable fees and disbursements of one firm of counsel designated by the Holders of a majority in principal amount of the Initial Securities covered thereby to act as counsel for the Holders of the Initial Securities in connection
therewith. 
 5. Indemnification. (a) The Company agrees to indemnify and hold harmless each Holder of the
Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any Participating Broker-Dealer and such
controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any
losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages,
liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus
or “issuer free writing prospectus,” as defined in Commission Rule 433 (“Issuer FWP”), relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon
any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration
in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder or Participating
Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered (including through satisfaction
of the conditions of Commission Rule 172) by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Holder or Participating Broker-Dealer
results from the fact that there was not conveyed to such person, at or prior to the time of the sale of such Securities to such person, an amended or supplemented prospectus or, if permitted by Section 3(d), an Issuer FWP correcting such
untrue statement or omission or alleged untrue statement or omission if the Company had previously furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition
to any liability which the Company may otherwise have to such Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or
the Exchange Act to the same extent as provided above with respect to the indemnification of the Holders of the Securities if requested by such Holders. 
 (b) Each Holder of the Securities, severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act
or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement
thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but
in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf
of such Holder specifically for inclusion therein; and, 

  
 10 

 
subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such
controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or
any of its controlling persons. 
 (c) Promptly after receipt by an indemnified party under this Section 5 of notice of
the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party
of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have under subsection (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 party shall not relieve it from any liability that it may have to an indemnified party otherwise
than under subsection (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein
and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the
indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party
under this Section 5 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such
settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a
failure to act by or on behalf of any indemnified party. 
 (d) If the indemnification provided for in this Section 5
is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the
one hand and the indemnified party on the other from the exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing 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) above but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with
the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties 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 on the one hand or such Holder or such other
indemnified party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending
any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), the Holders of the Securities shall not be required to contribute any amount in excess of the amount by which the net
proceeds received by such Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of damages which such Holders have 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. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and
each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company. 

  
 11 

 (e) The agreements contained in this Section 5 shall survive the sale of the
Securities pursuant to a Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 

6. Additional Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”)
with respect to the Initial Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (v) below a “Registration Default”): 

(i) If on or prior to the 180th day following the date of original issuance of the Initial Securities, the Exchange
Offer Registration Statement nor a Shelf Registration Statement has been filed with the Commission; 

(ii) If on or prior to the 60th day following the occurrence of an event requiring the filing of a Shelf Registration
Statement, the Shelf Registration Statement has not been filed with the Commission; 
 (iii) If on or prior
to the 270th day following the date of original issuance of the Initial Securities, the Exchange Offer Registration Statement has not been declared effective by the Commission (unless an event requiring the filing of a Shelf Registration Statement
in lieu of an Exchange Offer Registration Statement has occurred); 
 (iv) If on or prior to the 300th day
following the date of original issuance of the Initial Securities, neither the Registered Exchange Offer has been consummated nor, if required in lieu thereof, the Shelf Registration Statement has been declared effective by the Commission; or

 (v) If after either the Exchange Offer Registration Statement or the Shelf Registration Statement is
declared (or becomes automatically) effective (A) such Registration Statement thereafter ceases to be effective; or (B) such Registration Statement or the related prospectus ceases to be usable (except as permitted in paragraph (b))
in connection with resales of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any
untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, (2) it shall be necessary to amend such Registration
Statement or supplement the related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder, or (3) such Registration Statement is a Shelf Registration Statement that has expired before a replacement
Shelf Registration Statement has become effective. 
 Additional Interest shall accrue on the Initial Securities over and above the interest set
forth in the title of the Securities from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of 0.25% per annum (the
“Additional Interest Rate”) for the first 90-day period immediately following such Registration Default. The Additional Interest Rate shall increase by an additional 0.25% per annum with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum aggregate Additional Interest Rate of 0.50% per annum. The Company shall not be required to pay Additional Interest for more than one Registration Default at any given time.

 (b) A Registration Default referred to in Section 6(a)(v)(B) hereof shall be deemed not to have occurred and be
continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to
incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material
events, with respect to the Company that 

  
 12 

 
would need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or
supplement such Shelf Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable
in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. 

(c) Any amounts of Additional Interest due pursuant to clause (i), (ii), (iii), (iv) or (v) of Section 6(a) above will
be payable in cash on the regular interest payment dates with respect to the Initial Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Initial
Securities, multiplied by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of
which is 360. 
 (d) “Transfer Restricted Securities” means each Security until (i) the date on which
such Security has been exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an Initial
Security for an Exchange Security, the date on which such Exchange Security is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration
Statement, (iii) the date on which such Initial Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement, (iv) the earliest date that is no less than two years
after the Issue Date and on which all such Securities (except for Securities held by an affiliate of the Company) are no longer subject to any restrictions on transfer under the Securities Act including those pursuant to Rule 144. 

7. Rules 144 and 144A. The Company shall use its reasonable best efforts to file the reports required to be filed by it
under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the written request of any Holder of Initial Securities, make publicly available other information
so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any Holder of Initial Securities may reasonably request, all to the extent required from
time to time to enable such Holder to sell Initial Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company
will provide a copy of this Agreement to prospective purchasers of Initial Securities identified to the Company by the Initial Purchasers upon written request. Upon the written request of any Holder of Initial Securities, the Company shall deliver
to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange
Act. 
 8. Underwritten Registrations. If any of the Transfer Restricted Securities covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering (“Managing Underwriters”) will be selected by the Holders of a majority
in aggregate principal amount of such Transfer Restricted Securities to be included in such offering. 
 No person may
participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

 9. Miscellaneous. 
 (a) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be
given, except by the Company and the written consent of the Holders of a majority in principal amount of the Securities affected by such amendment, modification, supplement, waiver or consents.
