covering the offer by the Company to the Holders who are not prohibited by any law or policy of the SEC, or applicable interpretation of the Staff of the SEC, from participating in the Exchange Offer to exchange all of the Registrable Certificates

day period is not a business day, the first business day thereafter) (the “Exchange Deadline”). The Company shall commence the Exchange Offer by mailing the related exchange offer Prospectus and accompanying documents to each
Holder, through DTC or otherwise, stating in such Prospectus or accompanying documents, in addition to such other disclosures as are required by applicable law: 
 (i) that the Exchange Offer is being made pursuant to this Agreement and that all Registrable Certificates validly tendered and not withdrawn will be accepted for exchange; 

(ii) the dates of acceptance for exchange (which shall be a period of at least 20 business days from the date such
notice is mailed) (the “Exchange Dates”); 
 (iii) that any Registrable Certificate not tendered
will remain outstanding and continue to accrue interest, but will not retain any rights under this Registration Rights Agreement; 
 (iv) that Holders electing to have a Registrable Certificate exchanged pursuant to the Exchange 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 Exchange Date; and 

  
 5 








 (v) that Holders will be entitled to withdraw their election, not later than
the close of business on the last Exchange Date, by sending to the institution and at the address (located in the Borough of Manhattan, The City of New York) specified in the notice a telegram, facsimile transmission or letter setting forth the name
of such Holder, the principal amount of 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 Exchange Date, the Company shall: 

(i) accept for exchange Registrable Certificates or portions thereof tendered and not validly withdrawn pursuant to the
Exchange Offer; and 
 (ii) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable
Certificates or portions thereof so accepted for exchange by the Company and, subject to Section 4.01(f) and Section 4.03 of the Class A Trust Supplement, cause the Trustee to promptly issue, authenticate and mail to each Holder, an
Exchange Certificate equal in principal amount to the principal amount of the Registrable Certificates surrendered by such Holder. 
 The
Company shall use its reasonable best efforts to complete the 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 the Exchange
Offer. Except as set forth in Section 2(b), the Exchange Offer shall not be subject to any conditions, other than that the 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 Holders to whom the 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 Registrable Certificates in the Exchange Offer. 
 If the Company effects the Exchange
Offer, the Company shall be entitled to close the Exchange Offer twenty (20) business days after such commencement (provided that the Company has accepted all the Class A Certificates theretofore validly tendered and not withdrawn in
accordance with the terms of the Exchange Offer). 
 Each Holder participating in the Exchange Offer shall be required to represent to the
Company in writing that at the time of the consummation of the Exchange Offer (i) any Exchange Certificates received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or
understanding with any Person to participate in the distribution (within the meaning of the 1933 Act) of the Class A Certificates or the 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 the Exchange Certificates and (v) if such Holder is a broker dealer, that it will
receive Exchange Certificates for its own account in exchange for Class A Certificates that were acquired as a result of market making activities or other trading activities and that it will be required to acknowledge that it will deliver a
prospectus in connection with the resale of such Exchange Certificates. 

  
 6 








 (b) In the event that the Company determines (1) that the 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 Exchange
Certificates without transfer restrictions would cause the Class A Trust to be required to become registered as an investment company under the Investment Company Act of 1940, as amended, then the Company shall, in lieu of effecting the
registration of the Exchange Certificates pursuant to the Exchange Offer Registration Statement and at no cost to the holders of the Registrable Certificates, (i) as promptly as practicable, file with the SEC a shelf registration statement
covering resales of the Registrable Certificates (the “Shelf Registration Statement”), (ii) use its reasonable best efforts to cause the Shelf Registration Statement to be declared or otherwise become 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 the 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 Registrable Certificates covered by the 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 the 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 a 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 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 the 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 the Shelf Registration Statement. 
 (d) An Exchange Offer
Registration Statement pursuant to Section 2(a) hereof or a 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 Pass Through Trust Agreement, if neither the Exchange Offer is consummated nor the 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 Class A Certificates will be increased by 0.50% per annum effective as of the first day after the Shelf Registration Deadline but only until the Exchange Offer is consummated or the
Shelf Registration Statement is declared or otherwise becomes effective under SEC rules. If the 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 it is required to be available pursuant to Section 2(b), the interest rate per annum borne by the Class A Certificates shall be increased by 0.50% from the 46th day or 121st day, as applicable, until such time as the
Shelf Registration Statement again becomes available; provided that for the purpose of this sentence, the Shelf Registration Statement shall be deemed to have ceased to be available during: 

  
 7 









	 	(A)	any period in which the offering of Registrable Certificates pursuant to the 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 the 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(c) or 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 the 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 the Class A 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 Holders, the Company
acknowledges that 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 the Holders for which there is no adequate remedy
at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any 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 agrees that if the Class A Certificates
do not have an Investment Grade Rating and the 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 Certificate under a 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.

 12

pursuant to an Underwritten Offering and in such connection, (i) to the extent possible, make such representations and warranties to the Holders and the Underwriters of such Registrable Certificates with respect to the business of the Company
and its subsidiaries, the 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 the Majority Holders of Registrable
Certificates being sold and such Underwriters and their respective counsel) addressed to each selling Holder and Underwriter of 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 the Registration Statement) addressed to each selling Holder and Underwriter of Registrable Certificates, such letters to be in
customary form and 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 the Holders of a majority in principal amount of the Registrable Certificates being sold or the 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 Holder of Registrable Certificates to furnish to the Company such information regarding the 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 Holder who fails to furnish such information
within 30 days after receiving such request. Each 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 Registrable Securities sold
pursuant to the Shelf Registration Statement and, in the absence of a response, the Company may assume that all of the Holder’s Registrable Certificates were sold. 
 In the case of a Shelf Registration Statement, each 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 Registrable Certificates pursuant to a 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 Registrable 

  
 13 









 
Certificates pursuant to a Registration Statement, the Company shall extend the period during which the 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 the 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, the investment banker or investment bankers and manager or managers (such persons, the “Underwriters”) that will
administer the offering will be selected by the Majority Holders of the 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 receives Exchange Certificates for its own account in the Exchange Offer in exchange for Class A 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 it is the Staff’s position that if the Prospectus contained in the 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 Exchange Certificates, without naming the Participating Broker-Dealers or specifying the amount of Exchange Certificates owned by them, such Prospectus may be delivered by Participating Broker-Dealers to satisfy their
prospectus delivery obligation under the 1933 Act in connection with resales of 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 Exchange Certificates by 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 the Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i), (A) after the Participating Broker-Dealers shall have disposed of the Registrable Certificates or (B) for a
period exceeding 90 days after the last Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement) and 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 

  
 14 









 (ii) the application of the Shelf Registration procedures set forth in
Section 3 of this Agreement to an 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 Participating
Broker-Dealers; and provided further that, in connection with such application of the Shelf Registration procedures set forth in Section 3 to an Exchange Offer Registration, the Company shall be obligated (x) to deal only with the
two entities representing the 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 the
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 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 to indemnify and hold harmless the Initial Purchasers, each Holder and each Person, if any, who controls any Initial Purchaser or any 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 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 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 Registration Statement (or any amendment thereto) pursuant to which Exchange Certificates or 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 Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), any Free Writing Prospectus or any 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


  
 15 









 
omission based upon information relating to the Initial Purchasers or any Holder furnished to the Company in writing through Deutsche Bank, Morgan Stanley, Citigroup, Credit Suisse, Goldman Sachs
and J.P. Morgan or any selling Holder expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Company will also indemnify the 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
Registration Statement. 
 (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the
Initial Purchasers and the other selling Holders, and each of their respective directors, officers who sign the Registration Statement and each Person, if any, who controls the Company, any Initial Purchaser and any other 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 the 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 Registration Statement (or any amendment thereto), any Prospectus (or any amendment or supplement thereto) or any Free Writing Prospectus. 

(c) 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 Holders and all Persons, if any, who control any 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 the Holders and such Persons who control Holders, such firm shall
be designated in writing by the Majority Holders. In all other cases, such firm shall be designated by the Company. The indemnifying 

  
 16 









 
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 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 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 the Holders and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Holders’ respective obligations to contribute pursuant to this Section 5(d) are several in proportion to
the respective principal amount of Registrable Certificates of such Holder that were registered pursuant to a Registration Statement. 
 (e) The Company and each 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 Holder shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which 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 

  
 17 









 
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.

 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 Holder or any Person controlling any Initial Purchaser or any 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 Exchange Certificates and (iv) any sale of Registrable Certificates pursuant to a 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 Registrable Certificates in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of
the Company’s 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. 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 Holders of at least a majority in aggregate principal amount of the outstanding 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 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

 (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 Agreement. If any transferee of any Holder shall acquire
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)

or impaired thereby.
