Offer will be required to surrender such Registrable Certificate, together with the enclosed letters of transmittal, to the institution and at the address (located in the Borough of Manhattan, The City of New York) specified in the notice prior to
the close of business on the last applicable Exchange Date; and 
 (v) that applicable Holders will be entitled

facsimile transmission or letter setting forth the name of such Holder, the principal amount of the applicable Registrable Certificates delivered for exchange and a statement that such Holder is withdrawing his election to have such Registrable
Certificates exchanged.

 As soon as practicable after the last applicable Exchange Date for any such Exchange Offer,
the Company shall: 
 (i) accept for exchange the applicable Registrable Certificates or portions thereof
tendered and not validly withdrawn pursuant to such Exchange Offer; and 
 (ii) deliver, or cause to be
delivered, to the Trustee for cancellation all applicable Registrable Certificates or portions thereof so accepted for exchange by the Company and, subject to Section 4.01(f) and (with respect to the Class A Certificates) Section 4.03
of the Class A Trust Supplement and (with respect to the Class B Certificates) Section 4.04 of Class B Trust Supplement, cause the Trustee to promptly issue, authenticate and mail to each applicable Holder, an applicable Exchange
Certificate equal in principal amount to the principal amount of the applicable Registrable Certificates surrendered by such Holder. 
 The
Company, with respect to each Class of Certificates, shall use its reasonable best efforts to complete the applicable Exchange Offer as provided above and shall comply with the applicable requirements of the 1933 Act, the 1934 Act and other
applicable laws and regulations in connection with such Exchange Offer. Except as set forth in Section 2(b), such Exchange Offer shall not be subject to any conditions, other than that such Exchange Offer does not violate applicable law or any
applicable interpretation of the Staff of the SEC. The Company shall inform the Initial Purchasers of the names and addresses known to the Company (including through DTC) of the applicable Holders to whom such Exchange Offer is made, and the Initial
Purchasers shall have the right, subject to applicable law, to contact such Holders and otherwise facilitate the tender of the applicable Registrable Certificates in such Exchange Offer. 
 If the Company effects, with respect to each Class of Certificates, the applicable Exchange Offer, the Company shall be entitled to close such Exchange Offer twenty (20) business days after such
commencement (provided that the Company has accepted all the applicable Certificates theretofore validly tendered and not withdrawn in accordance with the terms of such Exchange Offer). 
 With respect to each Class of Certificates, each applicable Holder participating in the applicable Exchange Offer shall be required to represent to the Company in writing that at the time of the
consummation of such Exchange Offer (i) any applicable Exchange Certificates received by such Holder will be acquired by such Holder in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any
Person to participate in the distribution (within the meaning of the 1933 Act) of the applicable Certificates or such Exchange Certificates, (iii) such Holder is not an affiliate of the Company within the meaning of Rule 405 under the 1933
Act, (iv) if such Holder is not a broker dealer, that it is not engaged in and does not intend to engage in, the distribution of such Exchange Certificates and (v) if such Holder is a broker dealer, that such Holder will receive such
Exchange Certificates for its own account in exchange for such Certificates that were acquired as a result of market making activities or other trading activities and that such Holder will be required to acknowledge that it will deliver a prospectus
in connection with the resale of such Exchange Certificates. 

  
 7 

 (b) (X) With respect to each Class of Certificates, in the event that the Company determines
(1) that the applicable Exchange Offer Registration provided for in Section 2(a) above is not available or may not be consummated by the Exchange Deadline because it would violate applicable law or the applicable interpretations of
the Staff of the SEC or (2) the issuance of the applicable Exchange Certificates (without transfer restrictions in the case of the Class A Certificates) would cause the Class A Trust or the Class B Trust, as applicable, to be required
to become registered as an investment company under the Investment Company Act of 1940, as amended, or (Y) with respect to the Class B Certificates, in the event that the Company determines that the applicable Exchange Offer Registration
provided for in Section 2(a) above is not available to Class A Certificates or if such Exchange Offer Registration is not consummated for any reason and a Shelf Registration Statement is filed with respect to Class A Certificates
as provided below, then the Company (in the case of clause (X)) shall, and (in the case of clause (Y)) shall have the option to, in lieu of effecting the registration of the applicable Exchange Certificates pursuant to an Exchange Offer
Registration Statement and at no cost to the holders of the applicable Registrable Certificates, (i) as promptly as practicable, file with the SEC a shelf registration statement covering resales of the applicable Registrable Certificates (each,
a “Shelf Registration Statement”), (ii) use its reasonable best efforts to cause such Shelf Registration Statement to be declared or otherwise became effective under the Securities Act by the 90th day after the Exchange
Deadline (or, if such 90th day is not a business day, the first business day thereafter) (the “Shelf Registration Deadline”) and (iii) use its reasonable best efforts to keep effective such Shelf Registration Statement for a
period of one year after its effective date (or for such shorter period as shall end when all of the applicable Registrable Certificates covered by such Shelf Registration Statement have been sold pursuant thereto or may be freely sold pursuant to
Rule 144 under the Securities Act). The Company further agrees to supplement or amend any such Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the 1933 Act or by any other rules and regulations thereunder for shelf registration or if reasonably requested by an applicable Holder with respect to information relating to such Holder, and to use its reasonable
best efforts to cause any such amendment to become effective and such Shelf Registration Statement to become usable as soon as thereafter practicable. The Company agrees to furnish to the Holders of applicable Registrable Certificates copies of any
such supplement or amendment promptly after its being used or filed with the SEC. 
 (c) The Company shall pay all Registration
Expenses in connection with any registration pursuant to Section 2(a) and Section 2(b). Each Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such
Holder’s Registrable Certificates pursuant to a Shelf Registration Statement. 
 (d) With respect to each Class of
Certificates, an applicable Exchange Offer Registration Statement pursuant to Section 2(a) hereof or an applicable Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it
has been declared effective by the SEC or otherwise becomes effective under SEC rules. As provided for in the applicable Pass Through Trust Agreement, if neither such Exchange Offer is consummated nor such Shelf Registration Statement is declared
effective or otherwise becomes effective under SEC rules on or prior to the Shelf Registration Deadline, the interest rate on the Certificates of the applicable Class will be increased by 0.50% per annum effective as of the first

  
 8 

 
day after the Shelf Registration Deadline but only until such Exchange Offer is consummated or such Shelf Registration Statement is declared or otherwise becomes effective under SEC rules. If
such Shelf Registration Statement ceases to be available for more than 45 days during any three-month period or 120 days within any twelve-month period, during the period that such Shelf Registration Statement is required to be available
pursuant to Section 2(b), the interest rate per annum borne by the Certificates of the applicable Class shall be increased by 0.50% from the 46th day or 121st day, as applicable, until such time as such Shelf Registration Statement again
becomes available; provided that for the purpose of this sentence, such Shelf Registration Statement shall be deemed to have ceased to be available during: 
  

	 	(A)	any period in which the offering of the applicable Registrable Certificates pursuant to such Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental agency or court; 

  

	 	(B)	the occurrence of any event or the existence of any fact, as a result of which such Shelf Registration Statement shall contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, with respect to which notice has been given by the Company pursuant to Section 3(i); or 

 

	 	(C)	the occurrence or existence of any pending corporate development that, in the discretion of the Company, makes it appropriate to suspend the availability of such Shelf
Registration Statement with respect to which notice has been given by the Company pursuant to Section 3(e). 

(e) The maximum possible increase in the interest rate per annum on each Class of Certificates pursuant to Section 2(d) hereof,
at any time, shall be 0.50%. 
 (f) Without limiting the remedies available to the Initial Purchasers and the applicable Holders,
the Company acknowledges that, with respect to each Class of Certificates, any failure by the Company to comply with its obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the
Initial Purchasers or such Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any such Holder may
obtain such relief as may be required to specifically enforce the Company’s obligations under Section 2(a) and Section 2(b) hereof. 
 (g) Each Holder of Class A Certificates agrees that if the Class A Certificates do not have an Investment Grade Rating and such Holder is (i) an affiliate of the Company, or the
Class A Trust, or a broker-dealer selling or otherwise transferring Class A Certificates acquired directly from the Company for its own account, or (ii) an underwriter as defined in Section 2(a)(11) of the 1933 Act, such Holder
(a) may not resell or otherwise transfer such Class A Certificates under an applicable Shelf Registration Statement and (b) may only offer, sell or otherwise transfer such Class A Certificates to qualified institutional buyers
within the meaning of Rule 144A of the rules and regulations promulgated under the 1933 Act. 

  
 9 

 (h) Each Holder of Class B Certificates agrees that, for so long as Class B
Certificates remain outstanding, such Holder may only offer, sell or otherwise transfer Class B Certificates to qualified institutional buyers in compliance with, and within the meaning of, Rule 144A of the rules and regulations
promulgated under the 1933 Act. In addition, each Holder of Class B Certificates or Exchange Certificates issued with respect to Class B Certificates, as the case may be, agrees that, for so long as such Certificates remain outstanding, including
after the consummation of an Exchange Offer Registration as provided in Section 2(a) above or a Shelf Registration as provided in Section 2(b) above, such Certificates shall bear the restrictive legends set forth in
Section 4.02 or 4.03, as applicable, of the Class B Trust Supplement.

necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Company agrees to notify the applicable Holders to suspend use of such Prospectus as promptly as practicable after the

Shelf Registration Statement, the applicable Holders or their counsel) shall reasonably object, except for any amendment or supplement or document (a copy of which has been previously furnished
to the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, the applicable Holders and their counsel)) which counsel to the Company shall advise the Company in writing is required in order to comply with
applicable law; the Initial Purchasers agree, and, by virtue of the acquisition of the applicable Registrable Certificates, the applicable Holders agree, that, if they receive timely notice and documents under this clause (j), they will not
take actions or make objections under this clause (j) such that the Company is unable to comply with its obligations under Section 2(a) or Section 2(b) hereof; 

(k) obtain a CUSIP number for each of the applicable Exchange Certificates or the applicable Registrable Certificates, as
the case may be, not later than the effective date of an applicable Registration Statement (it being understood that the CUSIP number for Class B Certificates issued in connection with a Shelf Registration or Exchange Certificates issued with
respect to Class B Certificates in connection with Exchange Offer Registration will be a restricted CUSIP number that reflects the restrictive legends set forth in Section 4.03 of the Class B Trust Supplement); 

(l) cause the applicable Pass Through Trust Agreement to be qualified under the Trust Indenture Act of 1939, as amended
(the “TIA”), in connection with the registration of the applicable Exchange Certificates or applicable Registrable Certificates, as the case may be, cooperate with the Trustee and the applicable Holders to effect such changes to
such Pass Through Trust Agreement as may be required for such Pass Through Trust Agreement to be so qualified in accordance with the terms of the TIA and execute, and use its reasonable best efforts to cause the Trustee to execute, all documents as
may be required to effect such changes and all other forms and documents required to be filed with the SEC to enable such Pass Through Trust Agreement to be so qualified in a timely manner; 

(m) in the case of a Shelf Registration, make available for inspection by a representative of the applicable Holders of
the applicable Registrable Certificates, any applicable Underwriter participating in any disposition pursuant to such Shelf Registration Statement, and attorneys and accountants designated by such Holders, at reasonable times and in a reasonable
manner, all financial and other records, pertinent documents and properties of the Company, and cause the respective officers, directors and employees of the Company to supply all information reasonably requested by any such representative,
Underwriter, attorney or accountant in connection with such Shelf Registration Statement; provided, however, that any records, information or documents that are reasonably designated by the Company as confidential at the time of
delivery of such records, information or documents shall be kept confidential by such persons, unless (i) such records, information or documents are in the public domain or otherwise publicly available, (ii) disclosure of such records,
information or documents is required by court or administrative order or is necessary to respond to inquiries of regulatory authorities (subject to the requirements of such order, and only after such person shall have given the Company prompt, and,
if possible, at least 48 hours, prior written notice of such requirements so that the Company, at its expense, may undertake appropriate action to 

  
 13 

 
prevent disclosure of such information or records; provided that, should it be determined their disclosure is required, such person will take all precautions in consultation with the
Company to preserve the confidentiality of such records, information or documents), (iii) disclosure of such records, information or documents is required by law (including any disclosure requirements pursuant to federal securities laws in
connection with the filing of any Registration Statement or the use of any Prospectus referred to in this Agreement) or (iv) such records, information or documents become available to any such person from a source other than the Company and
that such person reasonably believes was entitled to disclose such records, information or documents to such person, and such sources is not subject to any contractual, legal, fiduciary or other obligation of confidentiality; 

(n) if reasonably requested by any applicable Holder of applicable Registrable Certificates covered by an applicable
Registration Statement, (i) promptly incorporate in a Prospectus supplement or post-effective amendment such information with respect to such Holder as such Holder reasonably requests to be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon as the Company has received notification of the matters to be incorporated in such filing; and 

(o) at least up until the applicable Exchange Deadline, use its reasonable best efforts to cause the applicable
Registrable Certificates or the applicable Exchange Certificates, as the case may be, to continue to be rated by two nationally recognized statistical rating organizations (as such term is defined in Section 3(a)(62) under the 1934 Act);

 (p) in the case of a Shelf Registration, enter into such customary agreements and take all such other actions
in connection therewith (including those requested by the applicable Majority Holders of Registrable Certificates being sold) in order to expedite or facilitate the disposition of such Registrable Certificates pursuant to an Underwritten Offering
and in such connection, (i) to the extent possible, make such representations and warranties to such Holders and the Underwriters of such Registrable Certificates with respect to the business of the Company and its subsidiaries, the applicable
Registration Statement, Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and
confirm the same if and when requested, (ii) obtain opinions of counsel to the Company (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to such Majority Holders and such Underwriters and their
respective counsel) addressed to each such selling Holder and Underwriter of such Registrable Certificates, covering the matters customarily covered in opinions requested in connection with underwritten firm commitment offerings, (iii) obtain
“cold comfort” letters from the independent certified public accountants of the Company (and, if necessary, any other certified public accountant of any subsidiary of the Company, or of any business acquired by the Company for which
financial statements and financial data are or are required to be included in such Registration Statement) addressed to each such selling Holder and Underwriter of such Registrable Certificates, such letters to be in customary form and

  
 14 

 
covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten firm commitment offerings, and (iv) deliver such documents and
certificates as may be reasonably requested by such Holders of a majority in principal amount of such Registrable Certificates being sold or such Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued
validity of the representations and warranties of the Company made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in an underwriting agreement. 

In the case of a Shelf Registration Statement, the Company may require each applicable Holder of the applicable Registrable Certificates
to furnish to the Company such information regarding such Holder and the proposed distribution by such Holder of such Registrable Certificates as the Company may from time to time reasonably request in writing. The Company may exclude from such
registrations the Registrable Certificate of any such Holder who fails to furnish such information within 30 days after receiving such request. Each such Holder further agrees, by acquisition of the Registrable Certificates, to notify the
Company, within ten business days of a request from the Company, of the amount of such Registrable Securities sold pursuant to such Shelf Registration Statement and, in the absence of a response, the Company may assume that all of such
Holder’s Registrable Certificates were sold. 
 In the case of a Shelf Registration Statement, each applicable Holder
agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(e)(v) hereof, such Holder will forthwith discontinue disposition of the applicable Registrable Certificates pursuant
to an applicable Shelf Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof, and, if so directed by the Company, such Holder will deliver to the
Company (at the Company’s expense) all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Certificates current at the time of receipt of such notice. If
the Company shall give any such notice to suspend the disposition of such Registrable Certificates pursuant to such Registration Statement, the Company shall extend the period during which such Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when such Holders shall have received copies of the supplemented or amended Prospectus
necessary to resume such dispositions. The Company may give any such notice only twice during any 365-day period and any such suspensions may not exceed 45 days for each suspension and there may not be more than two suspensions in effect during
any 365-day period. 
 The Holders of Registrable Certificates covered by a Shelf Registration Statement who desire to do so may
sell such Registrable Certificates in an Underwritten Offering. In any such Underwritten Offering if requested by the Majority Holders of such Registrable Certificates, the investment banker or investment bankers and manager or managers (such
person, the “Underwriters”) that will administer the offering will be selected by the Majority Holders of such Registrable Certificates included in such offering, subject to the consent of the Company (which shall not be
unreasonably withheld).

 4. Participation of Broker-Dealers in Exchange Offer. 

(a) The Staff of the SEC has taken the position that any broker-dealer that, with respect to each Class of Certificates, receives
applicable Exchange Certificates for its own account in the applicable Exchange Offer in exchange for such Certificates that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating
Broker-Dealer”), may be deemed to be an “underwriter” within the meaning of the 1933 Act and must deliver a prospectus meeting the requirements of the 1933 Act in connection with any resale of such Exchange Certificates.

 The Company understands that, with respect to each Class of Certificates, it is the Staff’s position that if the
Prospectus contained in the applicable Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the applicable Exchange
Certificates, without naming the Participating Broker-Dealers or specifying the amount of such Exchange Certificates owned by them, such Prospectus may be delivered by such Participating Broker-Dealers to satisfy their prospectus delivery obligation
under the 1933 Act in connection with resales of such Exchange Certificates for their own accounts, so long as the Prospectus otherwise meets the requirements of the 1933 Act. 
 (b) In light of Section 4(a), notwithstanding the other provisions of this Agreement, the Company agrees that the provisions of this Agreement as they relate to a Shelf Registration shall also apply
to an Exchange Offer Registration to the extent, and with such reasonable modifications thereto as may be, reasonably requested by the Initial Purchasers or by one or more Participating Broker-Dealers, in each case as provided in
clause (ii) below, in order to expedite or facilitate the disposition of any applicable Exchange Certificates by such Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above;
provided that: 
 (i) the Company shall not be required to amend or supplement the Prospectus contained in
such Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i), (A) after such Participating Broker-Dealers shall have disposed of the applicable Registrable Certificates or (B) for a period exceeding
90 days after the last applicable Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement) and such Participating Broker-Dealers shall not be authorized by the Company to
deliver and shall not deliver such Prospectus after such period in connection with the resales contemplated by this Section 4; and 
 (ii) the application of such Shelf Registration procedures set forth in Section 3 of this Agreement to such Exchange Offer Registration, to the extent not required by the positions of the Staff of
the SEC or the 1933 Act and the rules and regulations thereunder, will be in conformity with the reasonable request to the Company by the Initial Purchasers or with the reasonable request in writing to the Company by one or more broker-dealers who
certify to the Initial Purchasers and the Company in writing that they anticipate that they will be such Participating Broker-Dealers; and provided further that, in connection with such application of such Shelf Registration procedures
set forth 

  
 16 

 
in Section 3 to such Exchange Offer Registration, the Company shall be obligated (x) to deal only with two entities representing such Participating Broker-Dealers, which shall be
Deutsche Bank and Morgan Stanley unless they elect not to act as such representatives, (y) to pay the fees and expenses of only one counsel representing such Participating Broker-Dealers, which shall be counsel to the Initial Purchasers unless
such counsel elects not to so act and (z) to cause to be delivered only one, if any, “cold comfort” letter with respect to the Prospectus in the form existing on the last applicable Exchange Date and with respect to each subsequent
amendment or supplement, if any, effected during the period specified in clause (i) above. 
 (c) The Initial
Purchasers shall have no liability to the Company or any Holder with respect to any request that it may make pursuant to Section 4(b) above. 
 5. Indemnification and Contribution. 
 (a) The Company agrees, with respect
to each Class of Certificates, to indemnify and hold harmless the Initial Purchasers, each applicable Holder and each Person, if any, who controls any Initial Purchaser or any such Holder within the meaning of either Section 15 of the 1933 Act
or Section 20 of the 1934 Act, or is under common control with, or is controlled by, any Initial Purchaser or any such Holder, from and against all losses, claims, damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred by the Initial Purchasers, any such Holder or any such controlling or affiliated Person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in any applicable Registration Statement (or any amendment thereto) pursuant to which applicable Exchange Certificates or applicable Registrable Certificates were registered under the 1933 Act, including all documents
incorporated therein by reference, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or caused by any untrue statement or alleged
untrue statement of a material fact contained in any applicable Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), any applicable Free Writing Prospectus or any applicable Issuer
Information filed or required to be filed pursuant to Rule 433(d) under the 1933 Act in each case, taken together with such Prospectus, or caused by any omission or alleged omission to state therein a material fact necessary to make the
statements therein in the light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission
based upon information relating to the Initial Purchasers or any such Holder furnished to the Company in writing through Deutsche Bank, Morgan Stanley, Citigroup, Goldman Sachs and J.P. Morgan or any such selling Holder expressly for use therein. In
connection with any Underwritten Offering permitted by Section 3, the Company, with respect to each Class of Certificates, will also indemnify the applicable Underwriters, if any, and dealers participating in the distribution, their officers
and directors and each Person who controls such Persons (within the meaning of the 1933 Act and the 1934 Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any applicable
Registration Statement. 

  
 17 

 (b) Each Holder, with respect to each Class of Certificates, agrees, severally and not
jointly, to indemnify and hold harmless the Company, the Initial Purchasers and the other selling Holders of such Class, and each of their respective directors, officers who sign the applicable Registration Statement and each Person, if any, who
controls the Company, any Initial Purchaser and any other such selling Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Company to the
Initial Purchasers and such Holders, but only with reference to information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any such Registration Statement (or any amendment thereto), any applicable
Prospectus (or any amendment or supplement thereto) or any applicable Free Writing Prospectus. 
 (c) With respect to each Class
of Certificates, in case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to either paragraph (a) or paragraph (b) above, such
Person (the “indemnified party”) shall promptly notify the Person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party,
shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel
related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying
party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and
representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings
in the same jurisdiction, be liable for (a) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Initial Purchasers and all Persons, if any, who control any Initial Purchaser within the meaning of
either Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration
Statement and each Person, if any, who controls the Company within the meaning of either such Section and (c) the fees and expenses of more than one separate firm (in addition to any local counsel) for all applicable Holders and all
Persons, if any, who control any such Holders within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In such case involving the Initial Purchasers and Persons who control the Initial
Purchasers, such firm shall be designated in writing by the Initial Purchasers. In such case involving such Holders and such Persons who control such Holders, such firm shall be designated in writing by the applicable Majority Holders. In all other
cases, such firm shall be designated by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but, if settled with such consent or if there be a final judgment for the
plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have
requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any

  
 18 

 
proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request and
(ii) such indemnifying party shall not have reimbursed the indemnified party for such fees and expenses of counsel in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which such indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or failure to act by
or on behalf of such indemnified party. 
 (d) If the indemnification provided for in paragraph (a) or
paragraph (b) of this Section 5 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities, then each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying
party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the applicable Holders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or by such Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Such Holders’ respective
obligations to contribute pursuant to this Section 5(d) are several in proportion to the respective principal amount of the applicable Registrable Certificates of such Holder that were registered pursuant to an applicable Registration
Statement. 
 (e) With respect to each Class of Certificates, the Company and each applicable Holder agree that it would not be
just or equitable if contribution pursuant to this Section 5 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in
paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5, no such Holder shall be required to
indemnify or contribute any amount in excess of the amount by which the total price at which applicable Registrable Certificates were sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 

  
 19 

 With respect to each Class of Certificates, the indemnity and contribution provisions
contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers, any applicable Holder or
any Person controlling any Initial Purchaser or any such Holder, or by or on behalf of the Company, its officers or directors or any Person controlling the Company, (iii) acceptance of any of the applicable Exchange Certificates and
(iv) any sale of applicable Registrable Certificates pursuant to an applicable Shelf Registration Statement. 
 6.
Miscellaneous. 
 (a) No Inconsistent Agreements. The Company has not entered into, and on or after the date of
this Agreement will not enter into, any agreement which is inconsistent with the rights granted to the Holders of each Class of Registrable Certificates in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to such
Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s other issued and outstanding securities under any such agreements. For the avoidance of doubt, nothing herein
shall prevent the Company from entering into any registration rights agreement with respect to any of the Company’s issued and outstanding securities or any securities to be issued by the Company from time to time. 

(b) Amendments and Waivers. With respect to each Class of Certificates, the provisions of this Agreement, including the provisions
of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company has obtained the written consent of the applicable Holders of at least a majority in
aggregate principal amount of the outstanding applicable Registrable Certificates affected by such amendment, modification, supplement, waiver or consent; provided, however, that no amendment, modification, supplement, waiver or
consent to any departure from the provisions of Section 5 hereof shall be effective as against any such Holder of Registrable Certificates unless consented to in writing by such Holder. 

(c) Notices. All notices and other communications provided for or permitted hereunder shall be made in
writing by hand-delivery, registered first-class mail, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in accordance with
the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchasers, c/o Deutsche Bank Securities Inc., 60 Wall Street, Second Floor, New York, New York 10005, facsimile no. (212) 797-4877, attention:

guaranteeing overnight delivery. 
 Copies of all such notices, demands, or other communications shall be concurrently delivered
by the Person giving the same to the Trustee, at the address specified in the Pass Through Trust Agreements. 
 (d)
Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent
Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Certificates in violation of the terms of the Certificate Purchase Agreement or the Pass Through Trust Agreements. If
any transferee of any Holder shall acquire applicable Registrable Certificates, in any manner, whether by operation of law or otherwise, such Registrable Certificates shall be held subject to all of the terms of this Agreement, and by taking and
holding such Registrable Certificates such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof. The
Initial Purchasers (in their capacity as Initial Purchasers) shall have no liability or obligation to the Company with respect to any failure by a Holder to comply with, or any breach by any Holder of, any of the obligations of such Holder under
this Agreement. 
 (e) Purchases and Sales of Certificates. The Company shall not, and shall use its best efforts to
cause its affiliates (as defined in Rule 405 under the 1933 Act) not to, purchase and then resell or otherwise transfer any Certificates prior to the consummation of the applicable Exchange Offer or an applicable Shelf Registration Statement
being declared or otherwise becomes effective. 
 (f) Third Party Beneficiary. With respect to each Class of
Certificates, the Holders of such Certificates shall be third party beneficiaries to the applicable agreements made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce
such agreements directly to the extent the Initial Purchasers deem such enforcement necessary or advisable to protect its rights or the rights of such Holders hereunder. 
 (g) 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. 
 (h) Headings. The headings in this
Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. 

  
 21 

 (i) Governing Law. This Agreement shall be governed by the laws of the State of New
York. 
 (j) Severability. In the event that any one or more of the provisions contained herein, or the application
thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or impaired
thereby. 
 (k) Trustee. The Trustee shall take actions as may be reasonably requested by the Company in connection with
the Company satisfying its obligations arising under this Agreement.
