Global Markets Inc., J.P. Morgan Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and UBS Securities LLC (collectively, the “Dealer Managers”) in connection with the offer made by the Company to exchange
its 7.20% Notes due 2011, 7.0% Notes due 2012, 6.75% Notes due 2015 and 

  

 -1- 








 
6.572% Notes due 2017 (the “Initial Securities”) for up to U.S. $1,200,000,000 in the aggregate of the Parent’s issued and outstanding
7.20% Notes due 2011, 7.00% Notes due 2012 and 6.75% Notes due 2015, which are held by certain eligible holders. The Initial Securities will be issued pursuant to an Indenture, dated as of December 21, 2007 (the “Indenture”),
among the Company, as issuer, Parent, as guarantor, and 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 and the Parent agrees to cause the Company to perform its
obligations under this Agreement: 
 1. Registered Exchange Offer. Unless not permitted by applicable law, the Company and the Parent
shall prepare and, not later than 90 days (such 90th 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 Notes”),
guaranteed, to the extent applicable, on an unsecured senior basis by Parent (the “Exchange Guarantees” and, together with the Exchanged Notes, the “Exchange Securities”) identical in all material respects to the
Initial Securities and registered under the Securities Act. The Company shall use its reasonable best 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 240 days after the Closing Date (such 240th 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”). 
 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 

  

 -2- 








 
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. 
 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; 
  

 -3- 








 (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. 
 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. 
  

 -4- 








 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 90 days after the Trigger Date (such 90th day being a
“Filing Deadline”)) file with the Commission and thereafter use its best efforts to cause to be declared effective as soon as practicable and in any event no later than 120 days after the Trigger Date (such 120th 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 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 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 

  

 -5- 








 
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 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 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. 
 (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

broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange  

  

 -6- 








 
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. 
 (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. 
  

 -7- 








 (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). 
 (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. 
  


 -8- 








 (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. 
 (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 to Rule 144(k) 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 

  

 -10- 








 
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. 
 (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 therefor 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-

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. (“NASD”)) 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

 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 

  

 -13- 








 
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. 
 (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 

  

 -14- 








 
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 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) 

  

 -15- 








 
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. 
 (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 

  

 -16- 








 
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. 
 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. 
  

 -17- 








 (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(k) 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 communications provided for or permitted hereunder
shall be made in writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery:

 (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

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
                    , 200    , 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 to engage in, a distribution of Exchange Securities. If the undersigned is a broker-dealer that 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, 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.
