Each reference to a particular section set forth in this Eighth Supplemental Indenture shall, unless the context otherwise requires, refer
to this Eighth Supplemental Indenture. 
 ARTICLE TWO 

Designation and Terms of the Notes 
 Section 2.01. Establishment of Series 
 There is hereby created a
series of Securities to be known and designated as the “5.40% Notes Due 2021” (the “Initial Notes”), and, when and if issued pursuant to the Registration Rights Agreement, in exchange for Initial Notes, the “5.40%
Notes Due 2021” (such notes together with the Initial Notes, the “Notes”) which shall rank equally with each other and all other unsecured and unsubordinated indebtedness of the Company. For the purposes of the Original
Indenture, the Notes shall constitute a single series of Securities. 
 Section 2.02. Variations in Terms of the Notes

 Subject to the terms and conditions set forth in the Original Indenture and in this Eighth Supplemental Indenture, the
terms of any particular Note may vary from the terms of any other Note as contemplated by Section 301 of the Original Indenture, and the terms for a particular Note will be set forth in such Note as delivered to the Trustee or an Authenticating
Agent for authentication pursuant to Section 303 of the Original Indenture. 
 Section 2.03. Amount and
Denominations; the Depositary 
 (a) The initial principal amount of Notes that may be issued under this Eighth Supplemental
Indenture shall be $            . Additional Notes may be issued under this Eighth Supplemental Indenture in unlimited principal amounts as permitted by the Original Indenture. The
authorized denominations of Notes shall be $1,000 or integral multiples of $1,000 in excess thereof. 
 (b) The Notes shall be
issuable only in fully registered form, without coupons, and will initially be registered in the name of the Depositary, or its nominee who is hereby designated as “U.S. Depositary” under the Original Indenture. 

Section 2.04. Stated Maturity 
 The Stated Maturity of the principal amount of the Notes shall be May 15, 2021. 
 Section 2.05. Interest Rates and Interest Payment Dates 
 (a)
Interest Rate. The Notes shall bear interest at the annual rate of 5.40% from the Original Issue Date to the date on which the principal shall become due on the Stated Maturity, and if such principal is not fully paid on the Stated Maturity,
until such principal is paid in full. Interest on the Notes will be payable semi-annually on each Interest Payment Date, commencing on May 15, 2011. Such interest will be payable to the Holder thereof as of the related Record Date. 

  
 4 

 (b) Computation of Interest. The amount of interest payable for any period will be
computed on the basis of a year of 360 days consisting of twelve 30-day months. Except for the effect of any adjustment in the Interest Payment Date as provided in the following sentence, the amount of interest payable for any period shorter
than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 180-day period. If any Interest Payment Date would otherwise be a day that is not a Business Day, the payment
required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for the period from and after such Interest Payment Date to the date of such payment on the next
succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such Interest Payment
Date. 
 Section 2.06. Form and Other Terms of the Notes 

(a) Attached hereto as Exhibit A is the form of Note, which form is hereby established as the form in which the Notes may be issued
and which shall be completed with the series designation, Stated Maturity, interest rate and CUSIP number applicable to the Notes upon such issuance. Each Initial Note and any Note constituting a Restricted Security shall also bear the legend set
forth in Exhibit B-1. Notes offered and sold in offshore transactions in reliance on Regulation S under the Securities Act shall also bear the legend set forth in Exhibit B-2. 

(b) Subject to (a) above, any Note may be issued in such other form as may be provided by, or not inconsistent with, the terms of
the Original Indenture and this Eighth Supplemental Indenture. 
 Section 2.07. Authentication and Delivery

 As provided in and pursuant to Section 303 of the Original Indenture, each time that the Company delivers Notes to
the Trustee or Authenticating Agent for authentication after the initial issuance of Notes under this Eighth Supplemental Indenture, the Company shall deliver a Supplemental Company Order in the form of Exhibit C to this Eighth
Supplemental Indenture (which form shall be completed upon delivery with the series designation applicable to the Notes) for the authentication and delivery of such Notes and the Trustee or such Authenticating Agent shall authenticate and deliver
such Notes. 
 Section 2.08. Redemption; No Sinking Fund 

(a) The Notes are subject to redemption, in whole or in part, at any time, at the option of the Company, at a redemption price equal to
the greater of: 
 (i) 100% of the principal amount of Notes then outstanding to be redeemed, or 

  
 5 

 (ii) the sum of the present values of the remaining scheduled payments of
principal and interest on the Notes then outstanding to be redeemed (not including any portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (computed based on a 360-day year
consisting of twelve 30-day months) at the Treasury Rate, plus 25 basis points (0.25%), as calculated by an Independent Investment Banker, 

plus, in either of the above cases, accrued and unpaid interest thereon to the redemption date. 

(b) The Company will mail a notice of redemption at least 30 days but no more than 60 days before the redemption date to each Holder of

 Each purchaser of the Initial Notes will be deemed to have represented and agreed as follows
(terms used in this Section 3.01 that are defined in Rule 144A are used herein as defined therein): 
 (i)
The purchaser is either: (A) a qualified institutional buyer and is aware that the sale to it is being made in reliance on Rule 144A and such qualified institutional buyer is acquiring such securities for its own account or for the account of
another qualified institutional buyer; or (B) it or such investor account is a foreign purchaser outside the United States. 
 (ii) The purchaser understands that the Initial Notes are being offered in a transaction not involving any public offering in the United States within the meaning of the Securities Act, that the Initial

$50,000,000 and had stockholders’ or partners’ equity in excess of $750,000, as shown in its most recent balance sheet prepared in accordance with generally accepted accounting principles, or (B) a bank as defined in
Section 202(a)(2)of the 1940 Act that has the power to manage, acquire or dispose of assets of the plan and which bank has equity capital in excess of $1,000,000 as of the last day of its most recent fiscal year, or (C) an insurance

state of domicile of the insurer, in accordance with Prohibited Transaction Class Exemption 95- 60, and the conditions of Sections I and IV of such exemption are otherwise satisfied; 

  
 8 

 (vi) to the extent such purchase is made by an in-house asset manager within
the meaning of Part IV(a) of Prohibited Transaction Class Exemption 96-23, such manager has made or properly authorized the decision for such plan to purchase Notes, under circumstances such that Prohibited Transaction Class Exemption 96-23 is
applicable and satisfied with respect to the purchase and holding of such Notes; or 
 (vii) to the extent such
purchase will not otherwise give rise to a transaction described in Section 406 of ERISA or Section 4975(c)(1) of the Code for which a statutory or administrative exemption is unavailable.

 (REVERSE OF NOTE) 

TAMPA ELECTRIC COMPANY 
 5.40% Notes Due 2021 
 This Note is one of a duly authorized series of securities
of the Company (herein called the “Notes”), issued and to be issued under an Indenture dated as of July 1, 1998, as supplemented by the Eighth Supplemental Indenture, dated as of November 15, 2010 (as such has been or
shall be amended or supplemented, the “Indenture”), between the Company and The Bank of New York Mellon, as trustee (the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture
reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be,
authenticated and delivered. This Note is one of the securities of the series designated on the face hereof. 
 DEFINITIONS

 The following terms, as used herein, have the following meanings unless the context or use clearly indicates another or
different meaning or intent: 
 “Business Day” means any day other than (i) a Saturday or Sunday that is
neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulations to close in the City of New York, or (ii) a day on which the Corporate Trust Office of the Trustee is closed for business.

 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment
Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of the Notes; provided, however, that if the remaining term of the Notes to be redeemed is less than one year, the weekly average yield on actually traded United States Treasury securities
adjusted to a constant maturity of one year will be used. 
 “Comparable Treasury Price” means with respect to
any redemption date (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker obtains
fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Depositary”
shall mean The Depository Trust Company or any successor depositary. 
 “Independent Investment Banker” means
any of Citigroup Global Markets Inc., J.P. Morgan Securities LLC or any of their respective successors, as designated by the Company, or if all of those firms are unwilling or unable to serve as such, an independent investment and banking
institution of national standing appointed by the Company. 

  
 A-4

 “Interest Payment Date” means each of the dates on which interest on this
Note is payable, which dates are set forth on the face of this Note. 
 “Reference Treasury Dealer” means:

 (i) Citigroup Global Markets Inc., J.P. Morgan Securities LLC or their affiliates, and each of their
respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary
Treasury Dealer; and 
 (ii) up to three other Primary Treasury Dealers selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date,
the average, as determined by an Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent Investment Banker at
3:30 p.m., New York City time, on the third Business Day preceding such redemption date. 
 “Treasury Rate”
means, as of any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the second Business Day immediately preceding that redemption date) of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date. 
 INTEREST RATE 
 This Note will bear interest at the rate per annum
(computed based on a 360-day year consisting of twelve 30-day months) identified on the face of this Note. Except for the effect of any adjustment in the Interest Payment Date as provided in the following sentence, the amount of interest payable for
any period shorter than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 180-day period. If any Interest Payment Date would otherwise be a day that is not a Business
Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for the period from and after such Interest Payment Date to the date of such
payment on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on
such Interest Payment Date. 
 OPTIONAL REDEMPTION 

The Notes are subject to redemption, in whole or in part, at any time, at the option of the Company, at a redemption price equal to the
greater of: 
 (i) 100% of the principal amount of the Notes then outstanding to be redeemed, or 

  
 A-5

 (ii) the sum of the present values of the remaining scheduled payments of
principal and interest on the Notes then outstanding to be redeemed (not including any portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (computed based on a 360-day year
consisting of twelve 30-day months) at the Treasury Rate, plus 25 basis points (0.25%), as calculated by an Independent Investment Banker, 

plus, in either of the above cases, accrued and unpaid interest thereon to the redemption date. 

The Company will mail a notice of redemption at least 30 days but no more than 60 days before the redemption date to each Holder of the
Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select in a fair and appropriate manner the Notes to be redeemed. 
 Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. 

The Notes are not entitled to the benefit of any sinking fund or analogous provision. 

TRANSFER OR EXCHANGE 
 As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note is registerable in the Security Register, upon surrender of this Note for
registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes are issuable only in
registered form without coupons and, except for such Notes issued in book-entry form, only in denominations of $1,000 and any integral multiple of $1,000. As provided in the Indenture and subject to certain limitations herein and therein set forth,
this Note is exchangeable for a like aggregate principal amount of Notes of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this
Note for registration of transfer, the Company or the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and
neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 OTHER PROVISIONS

obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the
Securities at the time Outstanding of each series to be affected and of the Holders of 66 2/3% in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the
Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. To the extent permitted by law, any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of
any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of
(and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

 as Dealer Managers 
 Ladies
and Gentlemen: 
 This Registration Rights Agreement (the “Agreement”) is made in connection with (i) the
Dealer Manager Agreement, dated as of November 9, 2010 (the “Dealer Manager Agreement”), by and among Tampa Electric Company, a Florida corporation (the “Company”) and Citigroup Global Markets Inc., J.P. Morgan
Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. Incorporated (collectively, the “Dealer Managers”) and (ii) the offer made by the Company to exchange any and all of
its $250,000,000 aggregate principal amount outstanding 6.875% Notes due 2012 and any and all of its $400,000,000 aggregate principal amount outstanding 6.375% Notes due 2012, each for its newly issued 5.40% Notes due 2021 (the “Initial
Securities”). The Initial Securities will be issued pursuant to an Indenture, dated as of July 1, 1998 (the “Indenture”), among the Company, as issuer, and The Bank of New York Mellon (formerly known as The Bank of New
York), as trustee (the “Trustee”). As an inducement to the Dealer Managers to enter into the Dealer Manager Agreement, the Company agrees with the Dealer Managers, for the benefit of the holders of the Initial Securities and the
holders of the Exchange Securities (defined below) (collectively, the “Holders”), as follows: 
 1.
Registered Exchange Offer. Unless not permitted by applicable law, the Company shall prepare and, not later than 120 days (such 120th day being a “Filing Deadline”) after the date of the original issuance of the Initial
Securities (the “Closing 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 of the Company issued under the Indenture (the “Exchange Securities”) identical in all material respects to the Initial Securities and registered under the Securities Act. The Company shall use commercially reasonable
efforts to (i) cause such Exchange Offer Registration Statement to become effective under the Securities Act as soon as practicable and in any event within 270 days after the Closing Date (such 270th day being an “Effectiveness
Deadline”) and (ii) keep the Exchange Offer Registration Statement effective 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”). 

  
 -1-

 If the Company commences the Registered Exchange Offer, the Company (i) will be
entitled to consummate the Registered Exchange Offer 20 business days after such commencement (provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer) and (ii) will be required to consummate the Registered Exchange Offer no later than 30 business days after the date on which the Exchange Offer Registration Statement is declared effective (such 30th business day being the
“Consummation Deadline”). 
 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 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 Initial Securities or 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. 

  
 -2-

 The Company, the Dealer Managers and each Exchanging Dealer (as defined herein) acknowledge
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, each Holder that is a broker-dealer electing to exchange Initial 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. 
 The Company shall use its 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, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers 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 180 days after the consummation of the Registered Exchange Offer. 
 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; 

(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 Initial 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 laws applicable to the Registered Exchange Offer. 

  
 -3-

 As soon as practicable after the close of the Registered Exchange Offer, the Company shall:

 (x) accept for exchange all the Initial Securities validly tendered and not withdrawn pursuant to the
Registered Exchange Offer; 
 (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 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 Initial Securities and the Exchange Securities will vote and consent together on all matters as one class and that none of the Initial Securities or the Exchange Securities will have the right to vote or consent as a class separate from
one another on any matter. 
 Interest on each Exchange Security issued pursuant to the Registered Exchange Offer will accrue
from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefore 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 Initial 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 or (ii) any Holder of Transfer Restricted Securities notifies
the Company prior to the 20th business day following the
consummation of the Registered Exchange Offer that (A) it is prohibited by law or policy of the Commission from participating in the Registered Exchange Offer, (B) it may not resell the Exchange Securities acquired by it in the Registered
Exchange Offer to the public without delivering a prospectus and the prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resale or (C) that is a broker-dealer and owns the Initial
Securities acquired directly from the Company or an affiliate of the Company, the Company shall take the following actions (the date on which any of the conditions described in the foregoing clauses (i) through (ii) occur, including in the
case of clause (ii) the receipt of the required notice, a “Trigger Date”): 
 (a) The
Company shall promptly (but in no event more than 120 days after the Trigger Date (such 120th day being a “Filing Deadline”)) file with the Commission and thereafter use commercially reasonable efforts to cause to be declared
effective as soon as practicable and in any event no later than 150 days after the Trigger Date (such 150th day being an “Effectiveness Deadline”) 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 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 shall be entitled to have the Initial 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 commercially reasonable 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 covered thereby, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the
date of its effectiveness 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) are no longer restricted securities (as defined in
Rule 144 under the Securities Act, or any successor rule thereof) (the “Shelf Registration Period”). The Company shall be deemed not to have used commercially reasonable efforts to keep the Shelf Registration Statement
effective during the requisite period if it voluntarily takes any action that would result in Holders of Transfer Restricted Securities covered thereby not being able to offer and sell such Transfer Restricted Securities during that period, unless
such action is required by applicable law or otherwise permitted hereunder. 

  
 -5-

 (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) other than with respect to information included therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of any Holder specifically for use therein (the “Holders’ Information”), 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 the case of the prospectus, in light of the circumstances under which they were made) not misleading. 
 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 the
Dealer Managers, 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 the Dealer Managers (with
respect to any portion of an unsold allotment from the original offering) are participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its reasonable best efforts to reflect in each such document,
when so filed with the Commission, such comments as the Dealer Managers 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 the Dealer Managers, 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 Dealer Managers, 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 Securities Exchange Act of 1934, as amended (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 Dealer Managers 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 the names of the Holders who propose to sell Transfer Restricted Securities
pursuant to the Shelf Registration Statement as selling securityholders. 

  
 -6-

 (b) The Company shall give written notice to the Dealer Managers when the
Registration Statement or any amendment thereto has been filed with the Commission and shall give written notice to the Dealer Managers and (i) in the case of the Shelf Registration Statement the Holders of the Transfer Restricted Securities
covered thereby or (ii) in the case of the Exchange Offer Registration Statement, the Holders of the Initial 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 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; 
 (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; 
 (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 included therein 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) 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 thereto, including financial statements and schedules, and, if the Holder so
requests in writing, all exhibits thereto (including those, if any, incorporated by reference). 

  
 -7-

 (e) The Company shall deliver to each Exchanging Dealer and the Dealer
Managers, 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 Dealer Manager 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 the Dealer Managers, 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 the Dealer Managers, 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. 
 (h) Prior to any public offering of the Transfer Restricted 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 Transfer Restricted
Securities for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Transfer Restricted 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 Transfer Restricted 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 Transfer Restricted Securities pursuant to such Registration Statement. 

  
 -8-

 (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 purchasers of securities, the prospectus (other than the Holders’ Information) 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 the case of the prospectus, in light of the circumstances under which they were made) not misleading; provided,
however, that the Company may delay filing and distributing any such supplement or amendment if there is a possible acquisition or business combination or other transaction involving the Company that would require disclosure in the
Registration Statement or the related prospectus, and the Company determines in the exercise of its reasonable judgment that such disclosure is not in the best interest of the Company and its stockholders at such time; and provided,
further, that the Company will not be entitled to delay filing or distributing any such supplement or amendment for more than thirty (30) days (whether or not consecutive) in any period of three (3) consecutive months or more than
ninety (90) days for all such periods in any period of twelve (12) consecutive months. If the Company notifies the Dealer Managers, the Holders of the Transfer Restricted 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 Dealer Managers, the Holders of the Transfer Restricted Securities and
any such Participating Broker-Dealers shall suspend use of such prospectus and discontinue disposition of such securities until such Holder’s receipt of copies of the supplemental or amended prospectus or until advised in writing by the Company
that use of the applicable prospectus may be resumed, 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 Dealer Managers, the Holders of the Transfer Restricted Securities and any known Participating
Broker-Dealer shall have received such amended or supplemented prospectus or authorization to resume use of the applicable prospectus pursuant to this Section 3(j); provided, however, that such period of effectiveness including
any such extension shall not exceed the holding period applicable under Rule 144(d)(1)(i) of the Securities Act or any substitution or modification thereof. 
 (k) Not later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number for the Exchange Securities and provide the applicable trustee with printed
certificates for such Exchange Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company. 

  
 -9-

 (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. 
 (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 Transfer Restricted 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 Transfer Restricted 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 Transfer Restricted 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 Transfer Restricted Securities shall reasonably request in order to facilitate the disposition of the Transfer Restricted 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 Transfer Restricted 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 Transfer Restricted
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 Transfer Restricted 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
Dealer Managers 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; and, provided further, that such persons shall maintain in confidence
and use solely for the purposes of exercising their rights under this Agreement any information that is reasonably and in good faith designated by the Company as confidential at the time of delivery of such information, until such time as
(i) disclosure of such information is required by court or administrative order or is necessary to respond to inquiries of regulatory authorities, (ii) disclosure of such information is required by law (including any disclosure
requirements pursuant to federal securities laws in connection with the filing of any Registration Statement or the use of any prospectus referred to in this Agreement), (iii) such information becomes generally available to the public other
than as a result of a disclosure or failure to safeguard by such person, or (iv) such information becomes available to such person from a source other than the Company and, to the knowledge of such person after reasonable inquiry, such source
is not bound by a confidentiality agreement. 

  
 -10-

 (q) In the case of any Shelf Registration, the Company, if requested by
Holders of a majority in aggregate principal amount of Transfer Restricted Securities covered thereby, their counsel or managing underwriter, if any, shall cause its counsel to deliver opinions and updates thereof relating to the Transfer Restricted
Securities reasonably acceptable and 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; (ii) its
officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters of the applicable securities; and (ii) its independent registered certified public accountants to provide to the selling
Holders of the applicable Transfer Restricted Securities and any underwriter therefore a comfort letter and updates thereof 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. 
 (r) In the case of the Registered Exchange Offer, if requested by the Dealer Managers or any known Participating Broker-Dealer, the Company shall cause (i) its counsel to deliver to the Dealer
Managers or such Participating Broker-Dealer signed opinions and (ii) its independent registered certified public accountants to deliver to the Dealer Managers or such Participating Broker-Dealer a comfort letter, each of which shall be in
form, scope and substance reasonably satisfactory to the Dealer Managers, in the case of any underwritten registration, or covering such matters as are customarily covered in opinions or comfort letter, as applicable, requested in connection with
similar underwritten offerings and such other matters as may be reasonably requested by such Participating Broker Dealers and Managing Dealers. 
 (s) If a Registered Exchange Offer 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, the Company shall mark, or cause to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for the Exchange Securities in no event shall the Initial Securities be marked as paid or
otherwise satisfied. 

  
 -11-

 (t) In the event that any broker-dealer registered under the Exchange Act
shall underwrite any Transfer Restricted 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
National Association of Securities Dealers, Inc.) 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, without limitation, 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. 

(u) The Company shall use commercially reasonable efforts to take all other steps necessary to effect the registration of
the Transfer Restricted Securities covered by a Registration Statement contemplated hereby. 
 4. Registration Expenses.

 (a) All expenses incident to the Company’s performance of and compliance with this Agreement will be
borne by the Company, regardless of whether a Registration Statement is ever filed or becomes effective, including without limitation; 
 (i) all registration and filing fees and expenses; 
 (ii) all fees
and expenses of compliance with federal securities and state “blue sky” or securities laws; 
 (iii)
all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Registered Exchange Offer and printing of prospectuses), messenger and delivery services and telephone; 

(iv) all fees and disbursements of counsel for the Company; 

(v) all application and filing fees in connection with listing the Exchange Securities on a national securities exchange
or automated quotation system pursuant to the requirements hereof; and 
 (vi) all fees and disbursements of
independent registered certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance). 

  
 -12-

 Notwithstanding the foregoing, in no event shall the Company be responsible for underwriting
discounts or commissions or brokerage fees or commissions incurred by the selling Holders in connection with a Shelf Registration Statement. The Company will bear its internal expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any person, including special experts, retained by the Company. The Holders participating in any underwritten offering shall
be responsible for any underwriting discounts and commissions and fees and expenses of counsel to the managing underwriters and the selling securityholders to the extent not required to be paid by the Company pursuant to this Section 4.

 (b) In connection with any Registration Statement required by this Agreement, the Company will reimburse the
Holders of Transfer Restricted Securities who are tendering Initial Securities in the Registered Exchange Offer and/or selling or reselling such securities pursuant to the “Plan of Distribution” contained in the Exchange Offer Registration
Statement or the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel, who shall be Ropes & Gray LLP unless another firm shall be chosen by the Holders of a majority in
principal amount of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared. 
 5.
Indemnification. 
 (a) The Company agrees to indemnify and hold harmless each Holder of the securities
covered in any Registration Statement, 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 Transfer Restricted 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 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 (A) 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 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 or (B) any offer or sale of Transfer Restricted Securities covered by any Registration statement during a 30
day or 90 day period referenced in Section 3(j) hereof of which the Holder has received written notice 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 Transfer Restricted Securities concerned, to the extent that a prospectus relating to such securities was required to be delivered 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 sent or given to such person, at or prior to the written confirmation of the sale of such securities
to such person, a copy of the final prospectus if such loss, claim, damage or liability is determined by a court of competent jurisdiction to arise out of an untrue statement or omission that was corrected in the final prospectus and the Company had
previously furnished sufficient copies thereof to such Holder or Participating Broker-Dealer in sufficient time to enable such Holder or Participating Broker-Dealer to deliver to such person such prospectus; 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. 

  
 -13-

 (b) Each Holder of the securities covered under a Registration Statement,
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 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, 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. 

  
 -14-

 (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 omission so to notify the indemnifying party will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation
provided in paragraph (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 in such proportion as is appropriate to reflect 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 covered under any
Registration Statement 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 such 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. 

  
 -15-

 (e) The agreements contained in this Section 5 shall survive the sale
of the securities covered by 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 Payments Under Certain Circumstances. 

(a) Additional payment (the “Additional Payments”) with respect to the Transfer Restricted Securities
shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a “Registration Default”): 

(i) any Registration Statement required by this Agreement is not filed with the Commission on or prior to the applicable
Filing Deadline; 
 (ii) any Registration Statement required by this Agreement is not declared effective by the
Commission on or prior to the applicable Effectiveness Deadline; 
 (iii) the Registered Exchange Offer has not
been consummated on or prior to the Consummation Deadline; or 
 (iv) any Registration Statement required by this
Agreement has been declared effective by the Commission but (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, or (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. 

  
 -16-

 Each of the foregoing will constitute a Registration Default whatever the reason for any
such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission. 

Additional Payment shall accrue on the Transfer Restricted Securities over and above the interest set forth in the title of the Transfer
Restricted 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
Payment Rate”) for the first 90-day period immediately following the occurrence of such Registration Default. The Additional Payment 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 Additional Payment Rate of 1.0% per annum. 

(b) A Registration Default referred to in Section 6(a)(iv) 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 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 either proceeding promptly and in good faith to amend or
supplement such Shelf Registration Statement and related prospectus to describe such events or the Company has delayed filing and distributing such amendment or supplement pursuant to the first and second provisos of the first sentence of
Section 3(j) of this Agreement; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Payments 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 Payments due pursuant to Section 6(a) will be payable in cash on the regular interest payment dates with respect to the Transfer Restricted Securities. The amount of Additional Payments will be determined by multiplying the
applicable Additional Payment Rate by the principal amount of the Transfer Restricted Securities and further multiplied by a fraction, the numerator of which is the number of days such Additional Payment 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 Initial
Security or Exchange 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 security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or
(iv) the date on which such Security is distributed to the public pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule 144 under the Securities Act. 

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 request of any Holder of Transfer Restricted 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 Transfer Restricted Securities may reasonably request, all to the extent required
from time to time to enable such Holder to sell Transfer Restricted 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 Dealer Managers upon request. Upon the 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 Initial 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, subject to the approval of the Company (which shall not be unreasonably withheld) and provided that at least 10% of the outstanding
Transfer Restricted Securities are included in such underwritten offering. The Company shall not be obligated to arrange for more than two underwritten offerings during the Shelf Registration Period. 

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) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations
under Section 1 and 2 hereof may result in material irreparable injury to the Dealer Managers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in
the event of any such failure, the Dealer Managers or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Sections 1 and 2 hereof. The Company further agrees to waive the defense in
any action for specific performance that a remedy at law would be adequate. 
 (b) No Inconsistent
Agreements. The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s securities under any agreement in effect on the date hereof.

 (c) 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 Initial Securities (or, after the consummation of
any Registered Exchange Offer, in accordance with Section 1 hereof, of Exchange Securities) affected by such amendment, modification, supplement, waiver or consents. Without the consent of the Holder of each Security, however, no modification
may change the provisions relating to the Additional Payment. 
 (d) Notices. All notices and other

(k) Securities Held by the Company. Whenever the consent or approval of Holders of a specified percentage of
principal amount of the Initial Securities or the Exchange Securities is required hereunder, Initial Securities or the Exchange Securities, as applicable, held by the Company or its affiliates (other than subsequent Holders of Initial Securities or
Exchange Securities, if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required
percentage. 
 (l) Submission to Jurisdiction; Waiver of Jury Trial. The Company hereby submits to the
non-exclusive jurisdiction of the federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the parties hereto
hereby waives all right to trial by jury in any proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. Each of the Parties hereto agrees that a final judgment in any such proceeding
brought in any such court shall be conclusive and binding upon such party and may be enforced in any other courts in the jurisdiction of which such party is or may be subject, by suit upon such judgment.

 ANNEX A 
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange
Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See “Plan of Distribution.” 

 ANNEX B 
 Each broker-dealer that receives Exchange Securities for its own account in exchange for Initial Securities, where such Initial Securities were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.” 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each broker-dealer that receives
Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities. The
Company has agreed that, for a period of 180 days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until
                    , 201    , all dealers effecting transactions in the Exchange Securities may be required to deliver a
prospectus.(1) 
 The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be
sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the
time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates
in a distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an
“underwriter” within the meaning of the Securities Act. 
 For a period of 180 days after the Expiration Date the
Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to
the Exchange Offer (including the expenses of one counsel for the Holders of the Initial Securities) other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Initial Securities (including any
broker-dealers) against certain liabilities, including liabilities under the Securities Act. 
  

 

	(1)	 In addition, the legend, if any, required by Item 502(b) of Regulation S-K will appear on the inside front cover page of the Exchange Offer
prospectus below the Table of Contents.

 If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend

other trading activities, it acknowledges that it will deliver a prospectus in connection with any resale of such Exchange Securities; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it
is an “underwriter” within the meaning of the Securities Act.
