with respect to the Registered Exchange Offer. The Issuer and Parent shall use their commercially reasonable efforts to cause the Exchange Offer Registration Statement to become effective under the Securities Act by September 12, 2007.

 (b) Upon the effectiveness of the Exchange Offer Registration Statement, the Issuer and Parent shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder electing to exchange Original Floating Rate Notes for New Floating Rate Notes (assuming that such Original Floating Rate Notes do not constitute a portion
of an unsold allotment acquired by such Holder directly from the Issuer, such Holder is not an Affiliate of the Issuer or Parent, such Holder acquires the New Floating Rate Notes in the ordinary course of its business and such Holder has no
arrangements with any person to participate in the distribution of the New Floating Rate Notes) to trade such New Floating Rate Notes from and after their receipt without any limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of a substantial proportion of the several states of the United States. 
 (c) In connection with the
Registered Exchange Offer, the Issuer and Parent shall: 
 (i) 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; 
 (ii)
keep the Registered Exchange Offer open for not less than 20 business days after the date notice thereof is mailed to the Holders (or longer if required by applicable law); 
 (iii) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New
York; and 
  

 4 

 (iv) comply in all material respects with all applicable laws. 
 (d) As soon as practicable after the close of the Registered Exchange Offer, the Issuer and Parent shall: 
 (i) accept for exchange all Original Floating Rate Notes tendered and not validly withdrawn pursuant to the Registered Exchange Offer;

 (ii) deliver to the Trustee for cancellation all Original Floating Rate Notes so accepted for exchange; and 
 (iii) cause the Trustee promptly to authenticate and deliver to each Holder of Original Floating Rate Notes a principal amount of New
Floating Rate Notes equal to the principal amount of the Original Floating Rate Notes of such Holder so accepted for exchange. 
 (e) The
Purchasers, the Issuer and Parent acknowledge that, pursuant to current interpretations by the Commission’s staff of Section 5 of the Securities Act, and in the absence of an applicable exemption therefrom, each Exchanging Dealer is
required to deliver a Prospectus in connection with a sale of any New Floating Rate Notes received by such Exchanging Dealer pursuant to the Registered Exchange Offer in exchange for Original Floating Rate Notes acquired for its own account as a
result of market-making activities or other trading activities. Accordingly, the Issuer and Parent shall: 
 (i) include the
information set forth in Annex A hereto on the cover of the Exchange Offer Registration Statement, in Annex B hereto in the forepart of the Exchange Offer Registration Statement in a section setting forth details of the Exchange Offer, in
Annex C hereto in the underwriting or plan of distribution section of the Prospectus forming a part of the Exchange Offer Registration Statement, and in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered
Exchange Offer (it being understood that a Holder’s participation in the Exchange Offer is conditioned on the Holder, by executing and returning the Letter of Transmittal, representing in writing to the Issuer as set forth in Rider B of
Annex D hereto); and 
 (ii) use commercially reasonable efforts to keep the Exchange Offer Registration Statement
continuously effective under the Securities Act during the Exchange Offer Registration Period for delivery by Exchanging Dealers in connection with sales of New Floating Rate Notes received pursuant to the Registered Exchange Offer, as contemplated
by Section 4(h) below. 
 (f) In the event that any Purchaser determines that it is not eligible to participate in the Registered
Exchange Offer with respect to the exchange of Original Floating Rate Notes constituting any portion of an unsold allotment, at the request of such Purchaser, the Issuer and Parent shall issue and deliver to such Purchaser or the 

  

 5 

 
party purchasing New Floating Rate Notes registered under a Shelf Registration Statement as contemplated by Section 3 hereof from such Purchaser, in
exchange for such Original Floating Rate Notes, a like principal amount of New Floating Rate Notes. The Issuer and Parent shall seek to cause the CUSIP Service Bureau to issue the same CUSIP number for such New Floating Rate Notes as for New
Floating Rate Notes issued pursuant to the Registered Exchange Offer. 
 (g) Parent and the Issuer may include in the Exchange Offer
Registration Statement up to $700,000,000 aggregate principal amount of the Issuer’s 8.75% Senior Notes due 2017 (the “Original 2017 Notes”), guaranteed by Parent, to be exchanged for debt securities of the Issuer identical in all
material respects to the Original 2017 Notes (except that the interest rate step-up provisions and the transfer restrictions will be modified or eliminated, as appropriate) (the “New 2017 Notes”). 
 3. Shelf Registration. If, (i) because of any change in law or applicable interpretations thereof by the Commission’s staff, the Issuer
and Parent determine upon advice of outside counsel that they are not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for any other reason the Exchange Offer Registration Statement is not
declared effective by September 12, 2007 or the Registered Exchange Offer is not consummated within 30 business days following the initial effectiveness date of the Exchange Offer Registration Statement , or (iii) any Purchaser so requests
with respect to Original Floating Rate Notes (or any New Floating Rate Notes received pursuant to Section 2(f)) not eligible to be exchanged for New Floating Rate Notes in a Registered Exchange Offer or, in the case of any Purchaser that
participates in any Registered Exchange Offer, such Purchaser does not receive freely tradable New Floating Rate Notes, or (iv) any Holder (other than a Purchaser) is not eligible to participate in the Registered Exchange Offer or (v) in
the case of any such Holder that participates in the Registered Exchange Offer, such Holder does not receive freely tradable New Floating Rate Notes in exchange for tendered securities, other than by reason of such Holder being an affiliate of the
Issuer and Parent within the meaning of the Securities Act (it being understood that, for purposes of this Section 3, (x) the requirement that a Purchaser deliver a Prospectus containing the information required by Items 507 and/or
508 of Regulation S-K under the Securities Act in connection with sales of New Floating Rate Notes acquired in exchange for such Original Floating Rate Notes shall result in such New Floating Rate Notes being not “freely tradeable”
but (y) the requirement that an Exchanging Dealer deliver a Prospectus in connection with sales of New Floating Rate Notes acquired in the Registered Exchange Offer in exchange for Original Floating Rate Notes acquired as a result of
market-making activities or other trading activities shall not result in such New Floating Rate Notes being not “freely tradeable”), the following provisions shall apply: 
 (a) The Issuer and Parent shall as promptly as practicable (but in no event more than the later of (i) May 15, 2007 or (ii) 45 days after so
required or requested pursuant to this Section 3), file with the Commission and thereafter shall use their commercially reasonable efforts to cause to become effective under the Securities Act, or, 

  

 6 

 
if permitted by Rule 430B under the Securities Act, otherwise designate an existing registration statement filed with the Commission as, a Shelf Registration
Statement relating to the offer and sale of the Original Floating Rate Notes or the New Floating Rate Notes, as applicable, by the Holders from time to time in accordance with the methods of distribution elected by such Holders and set forth in such
Shelf Registration Statement (such Original Floating Rate Notes or New Floating Rate Notes, as applicable, to be sold by such Holders under such Shelf Registration Statement being referred to herein as “Registration Securities”);
provided, however, that, with respect to New Floating Rate Notes received by a Purchaser in exchange for Original Floating Rate Notes constituting any portion of an unsold allotment, the Issuer and Parent may, if permitted by current
interpretations by the Commission’s staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Regulation S-K Items 507 and/or 508, as applicable, in satisfaction of their
obligations under this paragraph (a) with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement.
Unless the Shelf Registration Statement is an automatic shelf registration statement (as defined in Rule 405 under the Securities Act), the Issuer and Parent shall include the information required by Rule 430B(b)(2)(iii) under the Securities
Act. 
 (b) The Issuer and Parent shall use their commercially reasonable efforts to keep the Shelf Registration Statement continuously
effective in order to permit the Prospectus forming part thereof to be usable by Holders for a period of two years from the date the Shelf Registration Statement becomes effective or is designated as such or such shorter period that will terminate
when all the Original Floating Rate Notes or New Floating Rate Notes, as applicable, covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (in any such case, such period being called the “Shelf
Registration Period”). The Issuer and Parent shall be deemed not to have used their commercially reasonable efforts to keep the Shelf Registration Statement effective during the Shelf Registration Period if the Issuer, or Parent voluntarily
takes any action that would result in Holders of securities covered thereby not being able to offer and sell such securities during that period, unless (i) such action is required by applicable law or (ii) such action is taken by such
party in good faith and for valid business reasons (not including avoidance of the obligations of the Issuer and Parent hereunder), including the acquisition or divestiture of assets, so long as the Issuer and Parent promptly thereafter comply with
the requirements of Section 4(k) hereof, if applicable. 
 (c) Parent and the Issuer may include in the Shelf Registration Statement up
to $700,000,000 aggregate principal amount of the Original 2017 Notes or the New 2017 Notes, as applicable, to be offered and sold by the holders thereof from time to time in accordance with the methods of distribution elected by such holders and
set forth in such Shelf Registration Statement.

therein not misleading and (iii) any Prospectus forming part of any Registration Statement, and any amendment or supplement to such Prospectus, does not include an untrue statement of a material fact or omit to state a material fact necessary

(1) The Issuer and Parent shall advise you and, in the case of a Shelf Registration Statement, the Holders of securities covered thereby, and, if requested by you or any such Holder, confirm such advice in writing: 
 (i) when a Registration Statement and any amendment thereto has been filed (or, in the case of a previously filed registration
statement designated as a Shelf Registration Statement, when it is so designated) with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective (or, in the case of a previously filed

advise you and, in the case of a Shelf Registration Statement, the Holders of securities covered thereby, and, in the case of an Exchange Offer Registration Statement, any Exchanging Dealer which has provided in writing to the Issuer a telephone or
facsimile number and address for notices, and, if requested by you or any such Holder or Exchanging Dealer, confirm such advice in writing: 
 (i) 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; 
 (ii) of the receipt by the Issuer or Parent 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 
 (iii) of the happening of any event that requires the making of any changes in the Registration Statement or the Prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact
required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading (which advice shall be accompanied by an instruction to suspend
the use of the Prospectus until the requisite changes have been made). 
 Each such Holder or Exchanging Dealer agrees by its acquisition of
such securities to be sold by such Holder or Exchanging Dealer, that, upon being so advised by the Issuer or Parent of any event described in clause (iii) of this paragraph (c)(2), such Holder or Exchanging Dealer will forthwith
discontinue disposition of such securities under such Registration Statement or Prospectus, until such Holder’s or Exchanging Dealer’s receipt of the copies of the supplemented or amended Prospectus contemplated by paragraph 4(k)
hereof, or until it is advised in writing by the Issuer or Parent that the use of the applicable Prospectus may be resumed. 
 (d) The Issuer and Parent shall use their commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time.

supplement thereto by each of the selling Holders of securities in connection with the offering and sale of the securities covered by the Prospectus or any amendment or supplement thereto.

such securities for offer and sale under the securities or blue sky laws of such jurisdictions as any such Holder 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 Issuer will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any
action which would subject it to general service of process or to taxation in any such jurisdiction where it is not then so subject. 
  

 10 

 (j) The Issuer and Parent shall cooperate with the Holders of Original Floating Rate
Notes to facilitate the timely preparation and delivery of certificates representing Original Floating Rate Notes to be sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such
names as Holders may request prior to sales of securities pursuant to such Registration Statement. 
 (k) Upon the occurrence
of any event contemplated by paragraph (c)(2)(iii) above, the Issuer and Parent shall promptly prepare a post-effective amendment to any Registration Statement or an amendment or supplement to the related Prospectus or file any other required
document so that, as thereafter delivered to purchasers of the securities included therein, the Prospectus will not include an 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. 
 (l) Not later than the effective date (or the
designation date, in the case of a previously filed registration statement that is effective at the time it is designated as a Shelf Registration Statement) of any such Registration Statement hereunder, the Issuer and Parent shall provide a CUSIP
number for each of the Original Floating Rate Notes or the New Floating Rate Notes, as the case may be, registered under such Registration Statement, and provide the Trustee with printed certificates for such Original Floating Rate Notes or New

 (m) The Issuer and Parent shall use their commercially reasonable efforts to comply with all applicable 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 the security holders of the Issuer a consolidated earning statement (which need not be
audited) covering a twelve-month period commencing after the effective date (or the designation date, in the case of a previously filed registration statement that is effective at the time it is designated as a Shelf Registration Statement) of the
Registration Statement and ending not later than 15 months thereafter, as soon as practicable after the end of such period, which consolidated earning statement shall satisfy the provisions of Section 11(a) of the Securities Act.

 (n) The Issuer and Parent shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, on
or prior to the effective date (or the designation date, in the case of a previously filed registration statement that is effective at the time it is designated as a Shelf Registration Statement) of any Shelf Registration Statement or Exchange Offer
Registration Statement. 
  

 11 

 (o) The Issuer and Parent may require each Holder of securities to be sold pursuant to
any Shelf Registration Statement to furnish to the Issuer in writing such information regarding the Holder and the distribution of such securities as the Issuer may from time to time reasonably require for inclusion in such Registration Statement.
The Issuer may exclude from any such Registration Statement the securities of any such Holder who fails to furnish such information within a reasonable time after receiving such request. Each Holder as to which any Shelf Registration is being
effected agrees to furnish promptly to the Issuer all information required to be disclosed in order to make the information previously furnished to the Issuer by such Holder not materially misleading. Each Holder further agrees that neither such
Holder nor any underwriter participating in any disposition pursuant to any Shelf Registration Statement on such Holder’s behalf will make any offer relating to the securities to be sold pursuant to such Shelf Registration Statement that would
constitute an issuer free writing prospectus (as defined in Rule 433 under the Securities Act) or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by the
Issuer and Parent with the Commission or retained by the Issuer and Parent under Rule 433 of the Securities Act, unless it has obtained the prior written consent of the Issuer and Parent (and except for as otherwise provided in any underwriting
agreement entered into by the Issuer and Parent and any such underwriter). 
 (p) The Issuer and Parent shall, if requested,
promptly incorporate in a Prospectus supplement or post-effective amendment to a Shelf Registration Statement, such information as the Managing Underwriters, if any, and the Floating Rate Majority Holders reasonably agree should be included therein
and shall make all required filings of such Prospectus supplement or post-effective amendment as soon as notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment. 
 (q) (i) In the case of any Shelf Registration Statement, the Issuer and Parent shall enter into such agreements (including
underwriting agreements) and take all other appropriate actions in order to expedite or facilitate the registration or the disposition of the Original Floating Rate Notes, and in connection therewith, if an underwriting agreement is entered into,
cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 6 hereof (or such other provisions and procedures acceptable to the Floating Rate Majority Holders and the Managing
Underwriters, if any), with respect to all parties to be indemnified pursuant to Section 6 hereof. 
 (ii) Without
limiting in any way paragraph (q)(i), no Holder may participate in any underwritten registration hereunder unless such Holder 

  

 12 

 
(x) agrees to sell such Holder’s securities to be covered by such registration on the basis provided in any underwriting arrangements approved by
the Floating Rate Majority Holders and the Managing Underwriters and (y) completes and executes in a timely manner all customary questionnaires, powers of attorney, underwriting agreements and other documents reasonably required by the Issuer
or the Managing Underwriters in connection with such underwriting arrangements. 
 (r) In the case of any Shelf Registration
Statement, the Issuer and Parent shall (i) make reasonably available for inspection by the Holders of securities to be registered thereunder, any underwriter participating in any disposition pursuant to such Registration Statement, and any
attorney, accountant or other agent retained by the Holders or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of Parent and its subsidiaries reasonably requested by such person;
(ii) cause the officers, directors and employees of the Issuer and Parent to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or agent in connection with any such Registration
Statement as is customary for due diligence examinations in connection with primary underwritten offerings; provided, however, that any information that is nonpublic at the time of delivery of such information shall be kept
confidential by the Holders or any such underwriter, attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a
third party without an accompanying obligation of confidentiality; (iii) make such representations and warranties to the Holders of securities registered thereunder and the underwriters, if any, in form, substance and scope as are customarily
made by an issuer to underwriters in primary underwritten offerings; (iv) obtain opinions of counsel to the Issuer and Parent (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the Managing
Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such
Holders and underwriters; (v) obtain “cold comfort” letters (or, in the case of any person that does not satisfy the conditions for receipt of a “cold comfort” letter specified in Statement on Auditing Standards No. 72,
an “agreed-upon procedures” letter under Statement on Auditing Standards No. 35) and updates thereof from the independent certified public accountants of Parent (and, if necessary, any other independent certified public accountants of
any subsidiary of Parent or of any business acquired by Parent for which financial statements and financial data are, or are required to be, included or incorporated by reference in the Registration Statement), addressed to each selling Holder of
securities registered thereunder and the underwriters, if any, in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with primary underwritten offerings; and (vi) deliver such
documents and certificates as may be reasonably requested by the Floating Rate Majority Holders and the Managing Underwriters, if any, 

  

 13 

 
including those to evidence compliance with Section 4(k) and with any customary conditions contained in the underwriting agreement or other agreement
entered into by the Issuer and Parent. The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of this Section 4(r) shall be performed (A) on the effective date (or the designation date, in the case of a previously
filed registration statement that is effective at the time it is designated as a Shelf Registration Statement) of such Registration Statement and each post-effective amendment thereto and (B) at each closing under any underwriting or similar
agreement as and to the extent required thereunder. 
 (s) In the case of any Exchange Offer Registration Statement, the
Issuer and Parent shall (i) make reasonably available for inspection by each Purchaser, and any attorney, accountant or other agent retained by such Purchaser, all relevant financial and other records, pertinent corporate documents and
properties of Parent and its subsidiaries reasonably requested by such person; (ii) cause the officers, directors and employees of the Issuer and Parent to supply all relevant information reasonably requested by such Purchaser or any such
attorney, accountant or agent in connection with any such Registration Statement as is customary for due diligence examinations in connection with primary underwritten offerings; provided, however, that any information that is
nonpublic at the time of delivery of such information shall be kept confidential by such Purchaser or any such attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such
information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality; (iii) make such representations and warranties to such Purchaser, in form, substance and scope as are
customarily made by an issuer to underwriters in primary underwritten offerings; (iv) obtain opinions of counsel to the Issuer and Parent (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to such
Purchaser and its counsel), addressed to such Purchaser, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Purchaser or its counsel;
(v) obtain “cold comfort” letters and updates thereof from the independent certified public accountants of Parent (and, if necessary, any other independent certified public accountants of any subsidiary of Parent or of any business
acquired by Parent for which financial statements and financial data are, or are required to be, included or incorporated by reference in the Registration Statement), addressed to such Purchaser, in customary form and covering matters of the type
customarily covered in “cold comfort” letters in connection with primary underwritten offerings, or if requested by such Purchaser or its counsel in lieu of a “cold comfort” letter, an agreed-upon procedures letter under
Statement on Auditing Standards No. 35, covering matters requested by such Purchaser or its counsel; and (vi) deliver such documents and certificates as may be reasonably requested by such Purchaser or its counsel, including those to

 5. Registration Expenses. The Issuer and Parent shall jointly and severally bear all expenses incurred in connection with the performance of their obligations under Sections 2, 3 and 4 hereof and, in the
event of any Shelf Registration Statement, will reimburse the Holders for the reasonable fees and disbursements of one firm or counsel (in addition to one local counsel in each relevant jurisdiction) designated by the Floating Rate Majority Holders
to act as counsel for the Holders in connection therewith. Notwithstanding the foregoing, the Holders of the securities being registered shall pay all agency or brokerage fees and commissions and underwriting discounts and commissions attributable
to the sale of such securities and the fees and disbursements of any counsel or other advisors or experts retained by such Holders (severally or jointly), other than the counsel and experts specifically referred to above in this Section 5,
transfer taxes on resale of any of the securities by such Holders and any advertising expenses incurred by or on behalf of such Holders in connection with any offers they may make. 
 6. Indemnification and Contribution. (a) In connection with any Registration Statement, the Issuer and Parent jointly and severally agree to
indemnify and hold harmless each Holder of securities covered thereby (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and
agents of each such Holder and each other person, if any, who controls any such Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities,
joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any preliminary
Prospectus or Prospectus, or in any amendment thereof or supplement thereto, or in any issuer free writing prospectus approved for use by the Issuer and Parent, 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 agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuer and Parent will not be liable in any case to the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuer or Parent by or on behalf of any such Holder
specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Issuer and Parent may otherwise have. 
  

 15 

 The Issuer and Parent also jointly and severally agree to indemnify or contribute to Losses (as defined
below) of, as provided in Section 6(d), any underwriters of Original Floating Rate Notes or New Floating Rate Notes registered under a Shelf Registration Statement, their officers, directors, employees and agents and each person who controls
such underwriters on substantially the same basis as that of the indemnification of the Purchasers and the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such
agreement, as provided in Section 4(q) hereof. 
 (b) Each Holder of securities covered by a Registration Statement (including each
Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally and not jointly agrees to indemnify and hold harmless the Issuer, Parent, each of their directors and officers and
each other person, if any, who controls the Issuer or Parent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Issuer and Parent to each such
Holder, but only with reference to written information relating to such Holder furnished to the Issuer by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability which any such Holder may otherwise have. 
 (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure
results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) 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. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided,
however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (and local counsel) if (i) the use of counsel chosen by the indemnifying
party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, 

  

 16 

 
or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that
there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably
satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at
the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. It is understood, however, that the Issuer and Parent shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel)
at any time for all such Holders and controlling persons. An indemnifying party shall not be liable under this Section 6 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such
settlement, compromise or consent is consented to by such indemnifying party, which consent shall not be unreasonably withheld. 
 (d) In the
event that the indemnity provided in paragraph (a) or (b) of this Section 6 is unavailable to or insufficient to hold harmless an indemnified party for any reason, then the Issuer, Parent and the Holders, in lieu of indemnifying such
indemnified party, shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same)
(collectively “Losses”) to which the Issuer, Parent and the Holders may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuer and Parent, on the one hand, and by the Holders, on the other
hand, from the Initial Placement and the Registration Statement which resulted in such Losses; provided, however, that in no case shall any Purchaser or any subsequent Holder of any Original Floating Rate Note or New Floating Rate Note
be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to such Original Floating Rate Note, or in the case of a New Floating Rate Note, applicable to the security which was exchangeable into such
New Floating Rate Note, as set forth in the Final Memorandum and in the Purchase Agreement, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such
underwriter under the Registration Statement which resulted in such Losses. If the 

  

 17 

 
allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuer, Parent and the Holders severally shall contribute in
such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer and Parent, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions which resulted in
such Losses as well as any other relevant equitable considerations. Benefits received by the Issuer and Parent shall be deemed to be equal to the sum of (x) the total net proceeds from the Initial Placement (before deducting expenses) as set
forth in the Final Memorandum and in the Purchase Agreement and (y) the total amount of additional interest which the Issuer was not required to pay as a result of registering the securities covered by the Registration Statement which resulted
in such Losses. Benefits received by the Purchasers shall be deemed to be equal to the total purchase discounts and commissions as set forth in the Final Memorandum and in the Purchase Agreement, and benefits received by any other Holders shall be
deemed to be equal to the value of receiving Original Floating Rate Notes or New Floating Rate Notes, as applicable, registered under the Securities Act. Benefits received by any underwriter shall be deemed to be equal to the total underwriting
discounts and commissions, as set forth on the cover page of the Prospectus forming a part of the Registration Statement which resulted in such Losses. Relative fault shall be determined by reference to whether any alleged untrue statement or
omission relates to information provided by the Issuer and Parent, on the one hand, or by Holders, on the other hand. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other
method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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 Section 6, each person who controls a Holder within the meaning of either the Securities Act
or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each person who controls the Issuer or Parent within the meaning of either the Securities Act or the
Exchange Act, each of their officers who shall have signed the Registration Statement and each of their directors shall have the same rights to contribution as the Issuer and Parent, subject in each case to the applicable terms and conditions of
this paragraph (d). 
 (e) The provisions of this Section 6 will remain in full force and effect, regardless of any investigation
made by or on behalf of any Purchaser, any other Holder, the Issuer and Parent or any underwriter or any of the officers, directors or controlling persons referred to in this Section 6, and will survive the sale by a Holder of securities
covered by a Registration Statement. 
  

 18 

 7. Miscellaneous. 
 (a) No Inconsistent Agreements. None of the Issuer or Parent has, as of the date hereof, entered into, nor shall it, on or after the date hereof, enter into, any agreement with respect to its securities that
limits the rights granted to the Holders herein or otherwise conflicts with the provisions hereof. 
 (b) Amendments and Waivers. The
provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Issuer has obtained the
written consent of the Holders of at least a majority of the then outstanding aggregate principal amount of Original Floating Rate Notes (or, after the consummation of any Exchange Offer in accordance with Section 2 hereof, of New Floating Rate
Notes); provided that, with respect to any matter that directly or indirectly affects the rights of any Purchaser hereunder, the Issuer shall obtain the written consent of each such Purchaser against which such amendment, qualification,
supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders
whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by the Floating Rate Majority Holders, determined on the basis of securities being sold
rather than registered under such Registration Statement. 
 (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail, facsimile, or air courier guaranteeing overnight delivery: 
 (1) if to a Holder, at the most current address given by such Holder to the Issuer in accordance with the provisions of this Section 7(c), which address initially is, with respect to each Holder, the address
of such Holder maintained by the registrar under the Indenture, with a copy in like manner to Merrill Lynch, Pierce, Fenner & Smith Incorporated by facsimile (212-449-3207) and confirmed by mail to it at Merrill Lynch World Headquarters,
North Tower, World Financial Center, New York, New York 10281-1201, Attention: Global Origination Counsel; 
 (2) if to
you, initially at the address set forth in the Purchase Agreement; and 
 (3) if to the Issuer or Parent, initially at
the address set forth in the Purchase Agreement. 
 All such notices and communications shall be deemed to have been duly given when
received. 
  

 19 

 The Purchasers or the Issuer by notice to the other may designate additional or different addresses for
subsequent notices or communications. 
 (d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon
the successors and assigns of each of the parties, including, without the need for an express assignment or any consent by the Issuer and Parent or subsequent Holders of Original Floating Rate Notes and/or New Floating Rate Notes. The Issuer and
Parent hereby agree to extend the benefits of this Agreement to any Holder of Original Floating Rate Notes and/or New Floating Rate Notes and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

 (e) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 
 (f) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. 
 (g) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS THEREOF). 

(h) Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby,
it being intended that all the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law. 
 (i)
Securities Held by the Issuer or Parent, etc. Whenever the consent or approval of Holders of a specified percentage of principal amount of Original Floating Rate Notes or New Floating Rate Notes is required hereunder, Original Floating Rate
Notes or New Floating Rate Notes, as applicable, held by the Issuer, Parent or their Affiliates (other than subsequent Holders of Original Floating Rate Notes or New Floating Rate Notes if such subsequent Holders are deemed to be Affiliates solely
by reason of their holdings of such Original Floating Rate Notes or New Floating Rate Notes) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 
 (j) Termination. This Agreement shall automatically terminate, without any further action on the part of the Issuer and Parent or the Purchasers,
upon the termination or cancellation of the Purchase Agreement prior to the Closing Date.

 Please confirm that the foregoing correctly sets forth the agreement among Parent, the Issuer and you.

 ANNEX A 
 Each broker-dealer that receives New Floating Rate Notes for its own account pursuant to the Registered Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New
Floating Rate Notes. 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 New Floating Rate Notes received in exchange for Original Floating Rate Notes where such New Floating Rate Notes were
acquired by such broker-dealer as a result of market-making activities or other trading activities. The Issuer and Parent have agreed that, starting on the date hereof (the “Expiration Date”) and ending on the close of business on the day
that is 180 days following the Expiration Date, 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 New Floating Rate Notes for its own account in exchange for Original Floating Rate Notes, where such Original Floating Rate Notes 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 New Floating Rate Notes. See “Plan of Distribution.” 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each broker-dealer that receives New Floating Rate Notes for its own account pursuant
to the Registered Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Floating Rate Notes. The Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of New Floating Rate Notes received in exchange for Original Floating Rate Notes where such Original Floating Rate Notes were acquired as a result of market-making activities or other trading activities. Each of the Issuer
and Parent has agreed that, starting on the Expiration Date and ending on the close of business on the day that is 180 days following 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                     , 2007, all dealers effecting transactions in the Exchange Securities
may be required to deliver a prospectus.* 
 Neither the Issuer nor Parent will receive any proceeds from any sale of New Floating Rate Notes
by broker-dealers. New Floating Rate Notes 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 New Floating Rate Notes 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 and/or the purchasers of any such New Floating Rate Notes. Any broker-dealer that resells
New Floating Rate Notes that were received by it for its own account pursuant to the Registered Exchange Offer and any broker or dealer that participates in a distribution of such New Floating Rate Notes may be deemed to be an
“underwriter” within the meaning of the Securities Act and any profit of any such resale of New Floating Rate Notes and any commissions 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 Issuer and Parent 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 Issuer and Parent have agreed to pay all expenses incident to the Exchange Offer (other than the expenses of counsel for
the Holders of the Original Floating Rate Notes) other than commissions or concessions of any brokers or

 dealers and will indemnify the Holders of the Original Floating Rate Notes (including any broker-dealers) against certain
liabilities, including liabilities under the Securities Act.

 (ii) keep the Registered Exchange Offer open for not less than 20 business days after the date notice thereof is mailed to the Holders (or longer if required by applicable law); 
 (iii) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New
York; and 
 (iv) comply in all material respects with all applicable laws. 
  

 4 

 (d) As soon as practicable after the close of the Registered Exchange Offer, the Issuer and Parent shall:

 (i) accept for exchange all Original 2017 Notes tendered and not validly withdrawn pursuant to the Registered Exchange
Offer; 
 (ii) deliver to the Trustee for cancellation all Original 2017 Notes so accepted for exchange; and 
 (iii) cause the Trustee promptly to authenticate and deliver to each Holder of Original 2017 Notes a principal amount of New 2017 Notes
equal to the principal amount of the Original 2017 Notes of such Holder so accepted for exchange. 
 (e) The Purchasers, the Issuer and
Parent acknowledge that, pursuant to current interpretations by the Commission’s staff of Section 5 of the Securities Act, and in the absence of an applicable exemption therefrom, each Exchanging Dealer is required to deliver a Prospectus
in connection with a sale of any New 2017 Notes received by such Exchanging Dealer pursuant to the Registered Exchange Offer in exchange for Original 2017 Notes acquired for its own account as a result of market-making activities or other trading
activities. Accordingly, the Issuer and Parent shall: 
 (i) include the information set forth in Annex A hereto on the
cover of the Exchange Offer Registration Statement, in Annex B hereto in the forepart of the Exchange Offer Registration Statement in a section setting forth details of the Exchange Offer, in Annex C hereto in the underwriting or plan of
distribution section of the Prospectus forming a part of the Exchange Offer Registration Statement, and in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer (it being understood that a Holder’s
participation in the Exchange Offer is conditioned on the Holder, by executing and returning the Letter of Transmittal, representing in writing to the Issuer as set forth in Rider B of Annex D hereto); and 
 (ii) use commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective under the Securities Act
during the Exchange Offer Registration Period for delivery by Exchanging Dealers in connection with sales of New 2017 Notes received pursuant to the Registered Exchange Offer, as contemplated by Section 4(h) below. 
 (f) In the event that any Purchaser determines that it is not eligible to participate in the Registered Exchange Offer with respect to the exchange of
Original 2017 Notes constituting any portion of an unsold allotment, at the request of such Purchaser, the Issuer and Parent shall issue and deliver to such Purchaser or the party purchasing New 2017 Notes registered under a Shelf Registration
Statement as contemplated by Section 3 hereof from such Purchaser, in exchange for such Original 2017 Notes, a like principal amount of New 2017 Notes. The Issuer and Parent shall seek to cause the CUSIP Service Bureau to issue the same CUSIP
number for such New 2017 Notes as for New 2017 Notes issued pursuant to the Registered Exchange Offer. 
  

 5 

 (g) Parent and the Issuer may include in the Exchange Offer Registration Statement up to $300,000,000
aggregate principal amount of the Issuer’s Floating Rate Senior Notes due 2015 (the “Original Floating Rate Notes”), guaranteed by Parent, to be exchanged for debt securities of the Issuer identical in all material respects to the
Original Floating Rate Notes (except that the interest rate step-up provisions and the transfer restrictions will be modified or eliminated, as appropriate) (the “New Floating Rate Notes”). 
 3. Shelf Registration. If, (i) because of any change in law or applicable interpretations thereof by the Commission’s staff, the Issuer
and Parent determine upon advice of outside counsel that they are not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for any other reason the Exchange Offer Registration Statement is not
declared effective by September 12, 2007 or the Registered Exchange Offer is not consummated within 30 business days following the initial effectiveness date of the Exchange Offer Registration Statement, or (iii) any Purchaser so requests
with respect to Original 2017 Notes (or any New 2017 Notes received pursuant to Section 2(f)) not eligible to be exchanged for New 2017 Notes in a Registered Exchange Offer or, in the case of any Purchaser that participates in any Registered
Exchange Offer, such Purchaser does not receive freely tradable New 2017 Notes, or (iv) any Holder (other than a Purchaser) is not eligible to participate in the Registered Exchange Offer or (v) in the case of any such Holder that
participates in the Registered Exchange Offer, such Holder does not receive freely tradable New 2017 Notes in exchange for tendered securities, other than by reason of such Holder being an affiliate of the Issuer and Parent within the meaning of the
Securities Act (it being understood that, for purposes of this Section 3, (x) the requirement that a Purchaser deliver a Prospectus containing the information required by Items 507 and/or 508 of Regulation S-K under the
Securities Act in connection with sales of New 2017 Notes acquired in exchange for such Original 2017 Notes shall result in such New 2017 Notes being not “freely tradeable” but (y) the requirement that an Exchanging Dealer deliver a
Prospectus in connection with sales of New 2017 Notes acquired in the Registered Exchange Offer in exchange for Original 2017 Notes acquired as a result of market-making activities or other trading activities shall not result in such New 2017 Notes
being not “freely tradeable”), the following provisions shall apply: 
 (a) The Issuer and Parent shall as promptly as practicable
(but in no event more than the later of (i) May 15, 2007 or (ii) 45 days after so required or requested pursuant to this Section 3), file with the Commission and thereafter shall use their commercially reasonable efforts to cause to
become effective under the Securities Act, or, if permitted by Rule 430B under the Securities Act, otherwise designate an existing registration statement filed with the Commission as, a Shelf Registration Statement relating to the offer and sale of
the Original 2017 Notes or the New 2017 Notes, as applicable, by the Holders from time to time in accordance with the methods of 

  

 6 

 
distribution elected by such Holders and set forth in such Shelf Registration Statement (such Original 2017 Notes or New 2017 Notes, as applicable, to be
sold by such Holders under such Shelf Registration Statement being referred to herein as “Registration Securities”); provided, however, that, with respect to New 2017 Notes received by a Purchaser in exchange for Original
2017 Notes constituting any portion of an unsold allotment, the Issuer and Parent may, if permitted by current interpretations by the Commission’s staff, file a post-effective amendment to the Exchange Offer Registration Statement containing
the information required by Regulation S-K Items 507 and/or 508, as applicable, in satisfaction of their obligations under this paragraph (a) with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be
referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement. Unless the Shelf Registration Statement is an automatic shelf registration statement (as defined in Rule 405 under the Securities Act), the
Issuer and Parent shall include the information required by Rule 430B(b)(2)(iii) under the Securities Act. 
 (b) The Issuer and Parent
shall use their commercially reasonable efforts to keep the Shelf Registration Statement continuously effective in order to permit the Prospectus forming part thereof to be usable by Holders for a period of two years from the date the Shelf
Registration Statement becomes effective or is designated as such or such shorter period that will terminate when all the Original 2017 Notes or New 2017 Notes, as applicable, covered by the Shelf Registration Statement have been sold pursuant to
the Shelf Registration Statement (in any such case, such period being called the “Shelf Registration Period”). The Issuer and Parent shall be deemed not to have used their commercially reasonable efforts to keep the Shelf Registration
Statement effective during the Shelf Registration Period if the Issuer, or Parent voluntarily takes any action that would result in Holders of securities covered thereby not being able to offer and sell such securities during that period, unless
(i) such action is required by applicable law or (ii) such action is taken by such party in good faith and for valid business reasons (not including avoidance of the obligations of the Issuer and Parent hereunder), including the
acquisition or divestiture of assets, so long as the Issuer and Parent promptly thereafter comply with the requirements of Section 4(k) hereof, if applicable. 
 (c) Parent and the Issuer may include in the Shelf Registration Statement up to $300,000,000 aggregate principal amount of the Original Floating Rate Notes or the New Floating Rate Notes, as applicable, to be offered
and sold by the holders thereof from time to time in accordance with the methods of distribution elected by such holders and set forth in such Shelf Registration Statement. 
 4. Registration Procedures. In connection with any Shelf Registration Statement and, to the extent applicable, any Exchange Offer Registration
Statement, the following provisions shall apply: 
 (a) (i) The Issuer and Parent shall furnish to you, prior to the
filing or designation thereof with the Commission, a copy of any Exchange Offer 

  

 7 

 
Registration Statement, each amendment thereof and each amendment or supplement, if any, to the Prospectus included therein and shall use its commercially
reasonable efforts to reflect in each such document, when so filed or designated with the Commission, such comments as you reasonably may propose. 
 (ii) The Issuer and Parent shall furnish to you, prior to the filing or designation thereof with the Commission, a copy of any Shelf Registration Statement, each amendment thereof and each amendment or supplement, if
any, to the Prospectus included therein and shall use its commercially reasonable efforts to reflect in each such document, when so filed or designated with the Commission, such comments as any Holder whose securities are to be included in such
Shelf Registration Statement reasonably may propose. 
 (b) The Issuer and Parent shall ensure that (i) any Registration
Statement and any amendment thereto and any Prospectus forming part thereof and any amendment or supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Registration
Statement and any amendment thereto does not, when it becomes effective (or, in the case of a previously filed registration statement that is effective at the time it is designated as a Shelf Registration Statement, when it is so designated),
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 Registration Statement, and
any amendment or supplement to such Prospectus, does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made,
not misleading. 
 (c) (1) The Issuer and Parent shall advise you and, in the case of a Shelf Registration Statement, the
Holders of securities covered thereby, and, if requested by you or any such Holder, confirm such advice in writing: 
 (i) when a Registration Statement and any amendment thereto has been filed (or, in the case of a previously filed registration statement designated as a Shelf Registration Statement, when it is so designated) with the Commission and
when the Registration Statement or any post-effective amendment thereto has become effective (or, in the case of a previously filed registration statement that is effective at the time it is designated as a Shelf Registration Statement, when it is
so designated); and 
 (ii) of any request by the Commission for amendments or supplements to the Registration Statement
or the Prospectus included therein or for additional information. 
  

 8 

 (2) The Issuer and Parent shall advise you and, in the case of a Shelf Registration
Statement, the Holders of securities covered thereby, and, in the case of an Exchange Offer Registration Statement, any Exchanging Dealer which has provided in writing to the Issuer a telephone or facsimile number and address for notices, and, if
requested by you or any such Holder or Exchanging Dealer, confirm such advice in writing: 
 (i) 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; 
 (ii) of the receipt by the Issuer or Parent 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 
 (iii) of the happening of any event that requires the making of any changes in
the Registration Statement or the Prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the
Prospectus, in the light of the circumstances under which they were made) not misleading (which advice shall be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made). 
 Each such Holder or Exchanging Dealer agrees by its acquisition of such securities to be sold by such Holder or Exchanging Dealer, that, upon being so
advised by the Issuer or Parent of any event described in clause (iii) of this paragraph (c)(2), such Holder or Exchanging Dealer will forthwith discontinue disposition of such securities under such Registration Statement or Prospectus,
until such Holder’s or Exchanging Dealer’s receipt of the copies of the supplemented or amended Prospectus contemplated by paragraph 4(k) hereof, or until it is advised in writing by the Issuer or Parent that the use of the applicable
Prospectus may be resumed. 
 (d) The Issuer and Parent shall use their commercially reasonable efforts to obtain the
withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time. 
 (e) The
Issuer and Parent shall furnish to each Holder of securities included within the coverage of any Shelf Registration Statement, without charge, at least one copy of such Shelf Registration Statement and any post-effective amendment thereto, including
financial statements and schedules, and, if the Holder so requests in writing, any documents incorporated by reference therein and all exhibits thereto (including those incorporated by reference therein). 
  

 9 

 (f) The Issuer and Parent shall, during the Shelf Registration Period, deliver to each
Holder of securities included within the coverage of any Shelf Registration Statement, without charge, as many copies of the Prospectus (including each preliminary Prospectus) included in such Shelf Registration Statement and any amendment or
supplement thereto as such Holder may reasonably request; and each of the Issuer and Parent hereby consent to the use of the Prospectus or any amendment or supplement thereto by each of the selling Holders of securities in connection with the
offering and sale of the securities covered by the Prospectus or any amendment or supplement thereto. 
 (g) The Issuer and
Parent shall furnish to each Exchanging Dealer which 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 the
Exchanging Dealer so requests in writing, any documents incorporated by reference therein and all exhibits thereto (including those incorporated by reference therein). 
 (h) The Issuer and Parent shall, during the Exchange Offer Registration Period, promptly deliver to each Exchanging Dealer, without
charge, as many copies of the Prospectus included in such Exchange Offer Registration Statement and any amendment or supplement thereto as such Exchanging Dealer may reasonably request for delivery by such Exchanging Dealer in connection with a sale
of New 2017 Notes received by it pursuant to the Registered Exchange Offer; and the Issuer and Parent hereby consent to the use of the Prospectus or any amendment or supplement thereto by any such Exchanging Dealer, as aforesaid. 
 (i) Prior to the Registered Exchange Offer or any other offering of securities pursuant to any Registration Statement, the Issuer shall
register or qualify or cooperate with the Holders of securities included therein and their respective counsel in connection with the registration or qualification of such securities for offer and sale under the securities or blue sky laws of such
jurisdictions as any such Holder 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 Issuer will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process or to taxation
in any such jurisdiction where it is not then so subject. 
 (j) The Issuer and Parent shall cooperate with the Holders of
Original 2017 Notes to facilitate the timely preparation and delivery of certificates representing Original 2017 Notes to be sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such
names as Holders may request prior to sales of securities pursuant to such Registration Statement. 
  

 10 

 (k) Upon the occurrence of any event contemplated by paragraph (c)(2)(iii) above,
the Issuer and Parent shall promptly prepare a post-effective amendment to any Registration Statement or an amendment or supplement to the related Prospectus or file any other required document so that, as thereafter delivered to purchasers of the
securities included therein, the Prospectus will not include an 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. 
 (l) Not later than the effective date (or the designation date, in the case of a previously filed registration
statement that is effective at the time it is designated as a Shelf Registration Statement) of any such Registration Statement hereunder, the Issuer and Parent shall provide a CUSIP number for each of the Original 2017 Notes or the New 2017 Notes,
as the case may be, registered under such Registration Statement, and provide the Trustee with printed certificates for such Original 2017 Notes or New 2017 Notes, in a form, if requested by the applicable Holder or Holder’s counsel, eligible
for deposit with The Depository Trust Company or any successor thereto under the Indenture. 
 (m) The Issuer and Parent shall
use their commercially reasonable efforts to comply with all applicable 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 the security holders of the Issuer a consolidated earning statement (which need not be audited) covering a twelve-month period commencing after the effective date (or the designation date, in the case of a previously filed registration
statement that is effective at the time it is designated as a Shelf Registration Statement) of the Registration Statement and ending not later than 15 months thereafter, as soon as practicable after the end of such period, which consolidated
earning statement shall satisfy the provisions of Section 11(a) of the Securities Act. 
 (n) The Issuer and Parent shall
cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, on or prior to the effective date (or the designation date, in the case of a previously filed registration statement that is effective at the time it is
designated as a Shelf Registration Statement) of any Shelf Registration Statement or Exchange Offer Registration Statement. 
 (o) The Issuer and Parent may require each Holder of securities to be sold pursuant to any Shelf Registration Statement to furnish to the Issuer in writing such information regarding the Holder and the distribution of such securities as the
Issuer may from time to time reasonably require for inclusion in such Registration Statement. The Issuer may exclude from any such Registration Statement the securities of any such Holder who fails to furnish such information within a reasonable
time after receiving such request. Each Holder as to which any Shelf Registration is being effected agrees to furnish promptly to the Issuer 

  

 11 

 
all information required to be disclosed in order to make the information previously furnished to the Issuer by such Holder not materially misleading. Each
Holder further agrees that neither such Holder nor any underwriter participating in any disposition pursuant to any Shelf Registration Statement on such Holder’s behalf will make any offer relating to the securities to be sold pursuant to such
Shelf Registration Statement that would constitute an issuer free writing prospectus (as defined in Rule 433 under the Securities Act) or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the
Securities Act) required to be filed by the Issuer and Parent with the Commission or retained by the Issuer and Parent under Rule 433 of the Securities Act, unless it has obtained the prior written consent of the Issuer and Parent (and except for as
otherwise provided in any underwriting agreement entered into by the Issuer and Parent and any such underwriter). 
 (p) The
Issuer and Parent shall, if requested, promptly incorporate in a Prospectus supplement or post-effective amendment to a Shelf Registration Statement, such information as the Managing Underwriters, if any, and the 2017 Majority Holders reasonably
agree should be included therein and shall make all required filings of such Prospectus supplement or post-effective amendment as soon as notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment.

 (q) (i) In the case of any Shelf Registration Statement, the Issuer and Parent shall enter into such agreements
(including underwriting agreements) and take all other appropriate actions in order to expedite or facilitate the registration or the disposition of the Original 2017 Notes, and in connection therewith, if an underwriting agreement is entered into,
cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 6 hereof (or such other provisions and procedures acceptable to the 2017 Majority Holders and the Managing Underwriters, if
any), with respect to all parties to be indemnified pursuant to Section 6 hereof. 
 (ii) Without limiting in any
way paragraph (q)(i), no Holder may participate in any underwritten registration hereunder unless such Holder (x) agrees to sell such Holder’s securities to be covered by such registration on the basis provided in any underwriting
arrangements approved by the 2017 Majority Holders and the Managing Underwriters and (y) completes and executes in a timely manner all customary questionnaires, powers of attorney, underwriting agreements and other documents reasonably required
by the Issuer or the Managing Underwriters in connection with such underwriting arrangements. 
 (r) In the case of any Shelf
Registration Statement, the Issuer and Parent shall (i) make reasonably available for inspection by the Holders of securities to be registered thereunder, any underwriter participating in any disposition pursuant to such Registration Statement,
and any attorney, accountant or other agent 

  

 12 

 
retained by the Holders or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of Parent and its
subsidiaries reasonably requested by such person; (ii) cause the officers, directors and employees of the Issuer and Parent to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or
agent in connection with any such Registration Statement as is customary for due diligence examinations in connection with primary underwritten offerings; provided, however, that any information that is nonpublic at the time of
delivery of such information shall be kept confidential by the Holders or any such underwriter, attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes
available to the public generally or through a third party without an accompanying obligation of confidentiality; (iii) make such representations and warranties to the Holders of securities registered thereunder and the underwriters, if any, in
form, substance and scope as are customarily made by an issuer to underwriters in primary underwritten offerings; (iv) obtain opinions of counsel to the Issuer and Parent (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the Managing Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as
may be reasonably requested by such Holders and underwriters; (v) obtain “cold comfort” letters (or, in the case of any person that does not satisfy the conditions for receipt of a “cold comfort” letter specified in
Statement on Auditing Standards No. 72, an “agreed-upon procedures” letter under Statement on Auditing Standards No. 35) and updates thereof from the independent certified public accountants of Parent (and, if necessary, any
other independent certified public accountants of any subsidiary of Parent or of any business acquired by Parent for which financial statements and financial data are, or are required to be, included or incorporated by reference in the Registration
Statement), addressed to each selling Holder of securities registered thereunder and the underwriters, if any, in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with primary
underwritten offerings; and (vi) deliver such documents and certificates as may be reasonably requested by the 2017 Majority Holders and the Managing Underwriters, if any, including those to evidence compliance with Section 4(k) and with
any customary conditions contained in the underwriting agreement or other agreement entered into by the Issuer and Parent. The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of this Section 4(r) shall be performed
(A) on the effective date (or the designation date, in the case of a previously filed registration statement that is effective at the time it is designated as a Shelf Registration Statement) of such Registration Statement and each
post-effective amendment thereto and (B) at each closing under any underwriting or similar agreement as and to the extent required thereunder. 
  

 13 

 (s) In the case of any Exchange Offer Registration Statement, the Issuer and Parent shall
(i) make reasonably available for inspection by each Purchaser, and any attorney, accountant or other agent retained by such Purchaser, all relevant financial and other records, pertinent corporate documents and properties of Parent and its
subsidiaries reasonably requested by such person; (ii) cause the officers, directors and employees of the Issuer and Parent to supply all relevant information reasonably requested by such Purchaser or any such attorney, accountant or agent in
connection with any such Registration Statement as is customary for due diligence examinations in connection with primary underwritten offerings; provided, however, that any information that is nonpublic at the time of delivery of such
information shall be kept confidential by such Purchaser or any such attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public
generally or through a third party without an accompanying obligation of confidentiality; (iii) make such representations and warranties to such Purchaser, in form, substance and scope as are customarily made by an issuer to underwriters in
primary underwritten offerings; (iv) obtain opinions of counsel to the Issuer and Parent (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to such Purchaser and its counsel), addressed to such
Purchaser, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Purchaser or its counsel; (v) obtain “cold comfort” letters and
updates thereof from the independent certified public accountants of Parent (and, if necessary, any other independent certified public accountants of any subsidiary of Parent or of any business acquired by Parent for which financial statements and
financial data are, or are required to be, included or incorporated by reference in the Registration Statement), addressed to such Purchaser, in customary form and covering matters of the type customarily covered in “cold comfort” letters
in connection with primary underwritten offerings, or if requested by such Purchaser or its counsel in lieu of a “cold comfort” letter, an agreed-upon procedures letter under Statement on Auditing Standards No. 35, covering matters
requested by such Purchaser or its counsel; and (vi) deliver such documents and certificates as may be reasonably requested by such Purchaser or its counsel, including those to evidence compliance with Section 4(k) and with conditions
customarily contained in underwriting agreements. The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of this Section 4(s) shall be performed (A) at the close of the Registered Exchange Offer and (B) on the
effective date of any post-effective amendment to the Exchange Offer Registration Statement. 
 5. Registration Expenses. The Issuer
and Parent shall jointly and severally bear all expenses incurred in connection with the performance of their obligations under Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the
reasonable fees and disbursements of one firm or counsel (in addition to one local counsel in each relevant jurisdiction) designated 

  

 14 

 
by the 2017 Majority Holders to act as counsel for the Holders in connection therewith. Notwithstanding the foregoing, the Holders of the securities being
registered shall pay all agency or brokerage fees and commissions and underwriting discounts and commissions attributable to the sale of such securities and the fees and disbursements of any counsel or other advisors or experts retained by such
Holders (severally or jointly), other than the counsel and experts specifically referred to above in this Section 5, transfer taxes on resale of any of the securities by such Holders and any advertising expenses incurred by or on behalf of such
Holders in connection with any offers they may make. 
 6. Indemnification and Contribution. (a) In connection with any
Registration Statement, the Issuer and Parent jointly and severally agree to indemnify and hold harmless each Holder of securities covered thereby (including each Purchaser and, with respect to any Prospectus delivery as contemplated in
Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each such Holder and each other person, if any, who controls any such Holder within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or Prospectus, or in any amendment thereof or supplement thereto, or in any issuer free writing prospectus approved for use by the Issuer and
Parent, 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 agrees to reimburse each such indemnified
party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuer and Parent will not be
liable in any case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with
written information furnished to the Issuer or Parent by or on behalf of any such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Issuer and Parent may otherwise have. 
 The Issuer and Parent also jointly and severally agree to indemnify or contribute to Losses (as defined below) of, as provided in Section 6(d), any
underwriters of Original 2017 Notes or New 2017 Notes registered under a Shelf Registration Statement, their officers, directors, employees and agents and each person who controls such underwriters on substantially the same basis as that of the
indemnification of the Purchasers and the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(q) hereof. 

 

 15 

 (b) Each Holder of securities covered by a Registration Statement (including each Purchaser and, with
respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally and not jointly agrees to indemnify and hold harmless the Issuer, Parent, each of their directors and officers and each other person,
if any, who controls the Issuer or Parent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Issuer and Parent to each such Holder, but only with
reference to written information relating to such Holder furnished to the Issuer by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any
liability which any such Holder may otherwise have. 
 (c) Promptly after receipt by an indemnified party under this Section 6 of notice
of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the commencement thereof; but the
failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) 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. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in
which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall
be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel
(including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (and local counsel) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party
would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel
reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or

consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding. It is understood, however, that the Issuer and Parent shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Holders and controlling persons. An
indemnifying party shall not be liable under this Section 6 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by such
indemnifying party, which consent shall not be unreasonably withheld. 
 (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 6 is unavailable to or insufficient to hold harmless an indemnified party for any reason, then the Issuer, Parent and the Holders, in lieu of indemnifying such indemnified party, shall have a joint and several
obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Issuer,
Parent and the Holders may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuer and Parent, on the one hand, and by the Holders, on the other hand, from the Initial Placement and the Registration
Statement which resulted in such Losses; provided, however, that in no case shall any Purchaser or any subsequent Holder of any Original 2017 Note or New 2017 Note be responsible, in the aggregate, for any amount in excess of the
purchase discount or commission applicable to such Original 2017 Note, or in the case of a New 2017 Note, applicable to the security which was exchangeable into such New 2017 Note, as set forth in the Final Memorandum and in the Purchase Agreement,
nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Registration Statement which resulted in such Losses. If the allocation
provided by the immediately preceding sentence is unavailable for any reason, the Issuer, Parent and the Holders severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault
of the Issuer and Parent, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Issuer and
Parent shall be deemed to be equal to the sum of (x) the total net proceeds from the Initial Placement (before deducting expenses) as set forth in the Final Memorandum and in the Purchase Agreement and (y) the total amount of additional
interest which the Issuer was not required to pay as a result of registering the securities covered by the Registration 

  

 17 

 
Statement which resulted in such Losses. Benefits received by the Purchasers shall be deemed to be equal to the total purchase discounts and commissions as
set forth in the Final Memorandum and in the Purchase Agreement, and benefits received by any other Holders shall be deemed to be equal to the value of receiving Original 2017 Notes or New 2017 Notes, as applicable, registered under the Securities
Act. Benefits received by any underwriter shall be deemed to be equal to the total underwriting discounts and commissions, as set forth on the cover page of the Prospectus forming a part of the Registration Statement which resulted in such Losses.
Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Issuer and Parent, on the one hand, or by Holders, on the other hand. The parties agree that it would not be
just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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
Section 6, each person who controls a Holder within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each
person who controls the Issuer or Parent within the meaning of either the Securities Act or the Exchange Act, each of their officers who shall have signed the Registration Statement and each of their directors shall have the same rights to
contribution as the Issuer and Parent, subject in each case to the applicable terms and conditions of this paragraph (d). 
 (e) The
provisions of this Section 6 will remain in full force and effect, regardless of any investigation made by or on behalf of any Purchaser, any other Holder, the Issuer and Parent or any underwriter or any of the officers, directors or
controlling persons referred to in this Section 6, and will survive the sale by a Holder of securities covered by a Registration Statement. 
 7. Miscellaneous. 
 (a) No Inconsistent Agreements. None of the Issuer or Parent has, as of the
date hereof, entered into, nor shall it, on or after the date hereof, enter into, any agreement with respect to its securities that limits the rights granted to the Holders herein or otherwise conflicts with the provisions hereof. 
 (b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified
or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Issuer has obtained the written consent of the Holders of at least a majority of the then outstanding aggregate principal amount of
Original 2017 Notes (or, after the consummation of any Exchange Offer in accordance with Section 2 hereof, of New 2017 Notes); provided that, with respect to any matter that directly or indirectly affects the rights of any Purchaser
hereunder, the Issuer shall obtain the written consent 

  

 18 

 
of each such Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except
the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose securities are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect the rights of other Holders may be given by the 2017 Majority Holders, determined on the basis of securities being sold rather than registered under such Registration Statement. 
 (c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail,
facsimile, or air courier guaranteeing overnight delivery: 
 (1) if to a Holder, at the most current address given by
such Holder to the Issuer in accordance with the provisions of this Section 7(c), which address initially is, with respect to each Holder, the address of such Holder maintained by the registrar under the Indenture, with a copy in like manner to
Merrill Lynch, Pierce, Fenner & Smith Incorporated by facsimile (212-449-3207) and confirmed by mail to it at Merrill Lynch World Headquarters, North Tower, World Financial Center, New York, New York 10281-1201, Attention: Global
Origination Counsel; 
 (2) if to you, initially at the address set forth in the Purchase Agreement; and 
 (3) if to the Issuer or Parent, initially at the address set forth in the Purchase Agreement. 
 All such notices and communications shall be deemed to have been duly given when received. 
 The Purchasers or the Issuer by notice to the other may designate additional or different addresses for subsequent notices or communications. 

(d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties,
including, without the need for an express assignment or any consent by the Issuer and Parent or subsequent Holders of Original 2017 Notes and/or New 2017 Notes. The Issuer and Parent hereby agree to extend the benefits of this Agreement to any
Holder of Original 2017 Notes and/or New 2017 Notes and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto. 
 (e) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement. 
  

 19 

 (f) Headings. The headings in this Agreement are for convenience of reference only and shall not
limit or otherwise affect the meaning hereof. 
 (g) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS THEREOF). 
 (h) Severability.
In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such
provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all the rights and privileges of the parties shall be enforceable to the fullest extent permitted by
law. 
 (i) Securities Held by the Issuer or Parent, etc. Whenever the consent or approval of Holders of a specified percentage of
principal amount of Original 2017 Notes or New 2017 Notes is required hereunder, Original 2017 Notes or New 2017 Notes, as applicable, held by the Issuer, Parent or their Affiliates (other than subsequent Holders of Original 2017 Notes or New 2017
Notes if such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Original 2017 Notes or New 2017 Notes) shall not be counted in determining whether such consent or approval was given by the Holders of such
required percentage. 
 (j) Termination. This Agreement shall automatically terminate, without any further action on the part of the
Issuer and Parent or the Purchasers, upon the termination or cancellation of the Purchase Agreement prior to the Closing Date.

 ANNEX A 
 Each broker-dealer that receives New 2017 Notes for its own account pursuant to the Registered Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New 2017 Notes.
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 New 2017 Notes received in exchange for Original 2017 Notes where such New 2017 Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Issuer and Parent have agreed that, starting on the date hereof (the “Expiration Date”) and ending on the close of business on the day that is 180 days following the Expiration
Date, 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 New 2017 Notes for its own account in exchange for Original 2017 Notes, where such Original 2017 Notes 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 New 2017 Notes. See “Plan of Distribution.” 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each broker-dealer that receives New 2017 Notes for its own account pursuant to the
Registered Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New 2017 Notes. The Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection
with resales of New 2017 Notes received in exchange for Original 2017 Notes where such Original 2017 Notes were acquired as a result of market-making activities or other trading activities. Each of the Issuer and Parent has agreed that, starting on
the Expiration Date and ending on the close of business on the day that is 180 days following 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 , 2007, all dealers effecting transactions in the Exchange Securities may be required to deliver a prospectus.* 
 Neither
the Issuer nor Parent will receive any proceeds from any sale of New 2017 Notes by broker-dealers. New 2017 Notes 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 New 2017 Notes 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 and/or the
purchasers of any such New 2017 Notes. Any broker-dealer that resells New 2017 Notes that were received by it for its own account pursuant to the Registered Exchange Offer and any broker or dealer that participates in a distribution of such New 2017
Notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit of any such resale of New 2017 Notes and any commissions 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 Issuer and Parent 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 Issuer and Parent have agreed to pay all expenses incident to the Exchange Offer (other than the
expenses of counsel for the Holders of the Original 2017 Notes) other than commissions or concessions of any brokers or
