 The Company and the Guarantors shall complete the Exchange Offer as provided above and shall
comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that the Exchange
Offer does not violate any applicable law or applicable interpretations of the Staff. 
 (b) In the event that, with respect to the
Securities, (i) the Company and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be completed as soon as practicable after the last Exchange Date because it would
violate any applicable law or applicable interpretations of the Staff, (ii) the Exchange Offer is not for any other reason consummated within 365 calendar days following the Closing Date, (iii) upon receipt of a written request from any
Initial Purchaser representing that it holds Registrable Securities that are or were ineligible to be exchanged in the Exchange Offer or (iv) in the case of any Holder that, prior to the close of business on the last Exchange Date, validly
tenders and does not properly withdraw Registrable Securities in the Exchange Offer, such Holder does not receive Exchange Securities on any Exchange Date that may be sold without restriction under state and federal securities laws (other than due
solely to the status of such Holder as an affiliate of the Company or any Guarantor within the meaning of the Securities Act) and so notifies (such notification or written request pursuant to the preceding clause (iii), a “Shelf
Request”) the Company within 30 days after such Holder first becomes aware of such restrictions, the Company and the Guarantors shall promptly file, but in any event within 30 days after the date of such determination, the date of expiry of
such 365 calendar day period, the date of receipt of such written notice or the date of receipt of such Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof
and shall use their commercially reasonable efforts to cause such Shelf Registration Statement to become effective within 90 days after the date of such determination or the date of receipt of such Shelf Request. 

In the event that the Company and the Guarantors are required to file a Shelf Registration Statement pursuant to clauses (iii) or (iv) of
the preceding sentence, the Company and the Guarantors shall file and use commercially reasonable efforts to cause to become effective both an Exchange Offer Registration Statement pursuant to Section 2(a) with respect to all Registrable Securities
and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by the Initial Purchasers or such Holder after
completion of the Exchange Offer. 
 The Company and the Guarantors agree to use their commercially reasonable efforts to keep the Shelf
Registration Statement continuously effective until the second anniversary of the Closing Date or such shorter period that will terminate when all the Registrable Securities covered by the Shelf Registration Statement have been sold pursuant to the
Shelf Registration Statement (the “Shelf Effectiveness Period”). The Company and the Guarantors further agree to supplement or amend the Shelf Registration Statement and the related Prospectus 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 Securities Act or by any other rules and regulations 

  
 6 








 
thereunder or if reasonably requested by a Holder of Registrable Securities with respect to information relating to such Holder, and to cause any such amendment to become effective and such Shelf
Registration Statement and Prospectus to become usable promptly thereafter. The Company and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed
with the SEC. 
 (c) The Company and the Guarantors shall pay all Registration Expenses in connection with any registration pursuant to
Section 2(a) or Section 2(b) hereof. Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities. 

(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. 
 In the event that either the Exchange Offer
is not completed or the Shelf Registration Statement, if required pursuant to Section 2(b)(i) or 2(b)(ii) hereof, does not become effective on or prior to the 365th calendar day after the Closing Date (the “Target Registration
Date”), the interest rate on the Securities will be increased by (i) 0.25% per annum for the first 90-day period immediately following the Target Registration Date and (ii) an additional 0.25%
per annum with respect to each subsequent 90 day period, in each case until the Exchange Offer is completed or the Shelf Registration Statement, if required hereby, becomes effective, up to a maximum increase of 1.00% per annum. In the event that
the Company receives a Shelf Request pursuant to Section 2(b)(iii), and the Shelf Registration Statement required to be filed thereby does not become effective by the 365th calendar day after the Closing Date, then the interest rate on the
Securities will be increased by 0.25% per annum for the first 90-day period payable commencing from one day after the Shelf Additional Interest Date and (ii) an additional 0.25% per annum with respect to
each subsequent 90 day period, in each case until the Shelf Registration Statement becomes effective, up to a maximum increase of 1.00% per annum. If the Shelf Registration Statement, if required hereby, has become effective and thereafter either
ceases to be effective or the Prospectus contained therein ceases to be usable, in each case whether or not permitted by this Agreement, at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for
more than 30 days (whether or not consecutive) in any 12-month period, then the interest rate on the Securities will be increased by (i) 0.25% per annum for the first
90-day period commencing on the 31st day in such 12-month period and (ii) an additional 0.25% per annum with respect to each subsequent 90 day period up to a
maximum of 1.00% per annum and ending on such date that the Shelf Registration Statement has again become effective or the Prospectus again becomes usable. Following the cure of all circumstances described in this section relating to any particular
Registrable Securities, all additional interest shall cease to accrue; provided, however, that, if after additional interest shall have ceased to accrue, a different circumstance described in this section providing for the payment of additional
interest occurs, additional interest shall again accrue pursuant to the foregoing provisions. All accrued additional interest shall be paid in the manner provided for the payment of interest on the Securities as set forth in the Indenture.
Notwithstanding the foregoing, the amount of additional interest shall not increase if more than one circumstance described in this section has occurred and is continuing at the same time.

 (e) Without limiting the remedies available to the Initial Purchasers and the Holders, the
Company and the Guarantors acknowledge that any failure by the Company and/or the Guarantors to comply with their 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 and the Guarantors’ obligations under Section 2(a) and Section 2(b) hereof.

a Shelf Registration Statement, the Company may require each Holder of Registrable Securities to furnish to the Company such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Company
may from time to time reasonably request in writing. 
 In the case of a Shelf Registration Statement, each Holder of Registrable Securities
covered by such Shelf Registration Statement 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
Securities pursuant to a 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
all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities that is current at the time of receipt of such notice. 

If the Company shall give any such notice to suspend the disposition of Registrable Securities 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 shall not exceed 30 days for each suspension and there shall not be more than two suspensions in effect during any 365-day period.

 4. Participation of Broker-Dealers in Exchange Offer. 

(a) The Staff has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in
exchange for Securities 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
Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities. 

The Company and the Guarantors understand 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 Securities, without naming the Participating Broker-Dealers or specifying
the amount of Exchange Securities owned by them, such Prospectus may be delivered (or, to the extent permitted by law, made available) by Participating Broker-Dealers to satisfy their prospectus delivery obligation under the Securities Act in
connection with resales of Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act. 

(b) In light of the above, and notwithstanding the other provisions of this Agreement, the Company and the Guarantors agree to amend or
supplement the Prospectus contained in the Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i) hereof, for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to the
final paragraph of Section 3 of this Agreement), if requested by the Initial Purchasers or by one or more Participating Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Securities by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Company and the Guarantors further agree that Participating Broker-Dealers shall be authorized to deliver (or, to the extent permitted by law, make
available) such Prospectus during such period in connection with the resales contemplated by this Section 4. 
 (c) The Initial
Purchasers shall have no liability to the Company, any Guarantor or any Holder with respect to any request that they may make pursuant to Section 4(b) above. 

5. Indemnification and Contribution. 

(a) The Company and each Guarantor, jointly and severally, agrees to indemnify and hold harmless the Initial Purchasers and each Holder, their
respective affiliates, directors and officers and each Person, if any, who controls an Initial Purchasers or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or
several, that arise out of, or are based 

  
 13 








 
upon, (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any Prospectus or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the statements therein (solely in the case of any Prospectus, in the light of the circumstances under which they were made) not misleading, or (2) any untrue statement or
alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus used in violation of this Agreement or any “issuer information” (“Issuer Information”) filed or required to be filed
pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading,
in each case, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information
relating to the Initial Purchasers or any Holder furnished to the Company in writing by the Initial Purchasers through the Representative or any selling Holder expressly for use therein. In connection with any Underwritten Offering permitted by
Section 3, the Company and the Guarantors, jointly and severally, will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective
affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any
Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information. 
 (b) Each Holder agrees, severally and not
jointly, to indemnify and hold harmless the Company, the Guarantors, the Initial Purchasers and the other selling Holders, their respective affiliates, the directors and officers of the Company and each Guarantor who sign a Registration Statement
and each Person, if any, who controls the Company, the Guarantors, the Initial Purchasers and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the
indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon
and in conformity with any information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement and any Prospectus. 

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted
against any Person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnification may
be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been
materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified
Person otherwise than under this Section 5. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably
satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may designate in such


  
 14 








 
proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person
has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in
addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the
same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be
liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm
(x) for the Initial Purchasers, their affiliates, directors and officers and any control Persons of an Initial Purchaser shall be designated in writing by the Initial Purchasers, (y) for any Holder, its affiliates, directors and officers
and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Company. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason
of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this
paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and
(ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any
settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an
unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to
or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. 
 (d) If the indemnification provided
for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of
indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Guarantors from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act,
on the other hand, or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in 

  
 15 








 
such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the
Holders 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 Guarantors on
the one hand and the Holders on the other hand 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 and the Guarantors or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e) The Company, the Guarantors and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5
were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) 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 Person 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 Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the
amount by which the total price at which the Securities or Exchange Securities 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 Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The
Holders’ obligations to contribute pursuant to this Section 5 are several and not joint. 
 (f) The remedies provided for in this
Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity. 

(g) 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 or any Holder, their respective affiliates or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of
the Company, its affiliates or the officers or directors of or any Person controlling the Company, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

 6. General. 
 (a)
No Inconsistent Agreements. The Company and the Guarantors represent, warrant and agree that (i) 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 any other outstanding securities issued or guaranteed by the Company or any Guarantor under any other agreement and (ii) neither the Company nor any Guarantor has entered into, or on or after the date of this Agreement will
enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. 

  
 16 








 (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 have obtained the written consent of Holders of at least a majority in
aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or consent; provided 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 Securities unless consented to in writing by such Holder. Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b) shall
be by a writing executed by each of the parties hereto. 
 (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, 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 Purchaser, the address set forth in the Purchase Agreement; (ii) if to the Company, initially at the
Company’s address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c); and (iii) to such other persons at their respective addresses as
provided in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c). All such notices and communications shall be deemed to have been duly given at the time
delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely
delivered to an air courier 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 Indenture. 

(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
Securities in violation of the terms of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held
subject to all the terms of this Agreement, and by taking and holding such Registrable Securities 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 the Initial Purchasers) shall have no liability or obligation to the Company or the Guarantors 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. 

  
 17 








 (e) Third Party Beneficiaries. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company and the Guarantors, 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 it deems such enforcement
necessary or advisable to protect its rights or the rights of other Holders hereunder. 
 (f) 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. 

(g) Headings. The headings in this Agreement are for convenience of reference only, are not a part of this Agreement and shall not
limit or otherwise affect the meaning hereof. 
 (h) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York. 
 (i) Miscellaneous. This Agreement contains the entire agreement between the
parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. The Company
and the Guarantors and the Initial Purchasers shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid,
void or unenforceable provisions.
