 2. Registration Under the Securities Act. 
 (a) Except as set forth in Section 2(b)(i) below, the Company agrees to file under the Securities Act, as soon as practicable, but no later than 90 days after the Closing Date, a registration statement relating to an offer to exchange
(such registration statement, the “Exchange Registration Statement”, and such offer, the “Exchange Offer”) any and all of the Securities for a like aggregate principal amount of debt securities issued by the Company and
guaranteed by the Guarantors, which debt securities and guarantees are substantially identical to the Securities and the related Guarantees, respectively (and are entitled to the benefits of a trust indenture which is substantially identical to the
Indenture or is the Indenture and which has been qualified under the Trust Indenture Act), except that they have been registered pursuant to an effective registration statement under the Securities Act and do not contain provisions for the Special
Interest contemplated in Section 2(c) below (such new debt securities hereinafter called “Exchange Securities”). The Company agrees to use its reasonable best efforts to cause the Exchange Registration Statement to become effective
under the Securities Act as soon as practicable, but no later than 180 days after the Closing Date. The Exchange Offer will be registered under the Securities Act on the appropriate form and will comply with all applicable tender offer rules and
regulations under the Exchange Act. The Company further agrees to use its reasonable best efforts to commence and complete the Exchange Offer promptly, but no later than 30 days after such registration statement has become effective, hold the
Exchange Offer open for at least 20 business days and exchange Exchange Securities for all Registrable Securities that have been validly tendered and not validly withdrawn on or prior to the expiration of the Exchange Offer. The Exchange Offer will
be deemed to have been “completed” only if the debt securities and related guarantees received by holders, other than Restricted Holders, in the Exchange Offer for Registrable Securities are, upon receipt, transferable by each such holder
without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a substantial majority of the States of the United States of America. The Exchange Offer shall be deemed to
have been completed upon the earlier to occur of (i) the Company having exchanged the Exchange Securities for all outstanding Registrable Securities pursuant to the Exchange Offer and (ii) the Company having exchanged, pursuant to the
Exchange Offer, Exchange Securities for 

  

 4 

 
all Registrable Securities that have been validly tendered and not validly withdrawn before the expiration of the Exchange Offer. The Company agrees (x) to
include in the Exchange Registration Statement a prospectus for use in any resales by any holder of Exchange Securities that is a broker-dealer and (y) to keep such Exchange Registration Statement effective for a period (the “Resale
Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 180th day after the Exchange Offer has been completed or such time as such broker-dealers no longer own any
Registrable Securities. With respect to such Exchange Registration Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Sections 6(a), (c), (d) and (e) hereof. 
 (b) If (i) on or prior to the time the Exchange Offer is completed existing Commission interpretations are changed such that the debt
securities or the related guarantees received by holders other than Restricted Holders in the Exchange Offer for Registrable Securities are not or would not be, upon receipt, transferable by each such holder without restriction under the Securities
Act, (ii) the Exchange Offer has not been completed within 210 days following the Closing Date or (iii) the Exchange Offer is not available to any holder of the Securities, the Company shall, in lieu of (or, in the case of clause (iii), in
addition to) conducting the Exchange Offer contemplated by Section 2(a), file under the Securities Act as soon as practicable, but no later than 30 days after the time such obligation to file arises, a “shelf” registration statement
providing for the registration of, and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the Commission (such filing, the “Shelf
Registration” and such registration statement, the “Shelf Registration Statement”). The Company agrees to use its reasonable best efforts (x) to cause the Shelf Registration Statement to become or be declared effective no later
than 120 days after such Shelf Registration Statement is filed and to keep such Shelf Registration Statement continuously effective for a period ending on the earlier of the second anniversary of the Effective Time or such time as there are no
longer any Registrable Securities outstanding, provided, however, that no holder shall be entitled to be named as a selling securityholder in the Shelf Registration Statement or to use the prospectus forming a part thereof for resales
of Registrable Securities unless such holder is an Electing Holder, and (y) after the Effective Time of the Shelf Registration Statement, promptly upon the request of any holder of Registrable Securities that is not then an Electing Holder, to
take any action reasonably necessary to enable such holder to use the prospectus forming a part thereof for resales of Registrable Securities, including, without limitation, any action necessary to identify such holder as a selling securityholder in
the Shelf Registration Statement, provided, however, that nothing in this Clause (y) shall relieve any such holder of the obligation to return a completed and signed Notice and Questionnaire to the Company in accordance with
Section 3(d)(iii) hereof. The Company further agrees to supplement or make amendments to the Shelf Registration Statement, as and when 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 rules and regulations thereunder for shelf registration, and the Company agrees to furnish to each Electing Holder copies of any such supplement or amendment prior to its being used
or promptly following its filing with the Commission. 
 (c) In the event that (i) the Company has not filed the Exchange
Registration Statement or Shelf Registration Statement on or before the date on which such registration statement is required to be filed pursuant to Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement or Shelf
Registration Statement has not become effective or been 

  

 5 

 
declared effective by the Commission on or before the date on which such registration statement is required to become or be declared effective pursuant to
Section 2(a) or 2(b), respectively, or (iii) the Exchange Offer has not been completed within 30 days after the initial effective date of the Exchange Registration Statement relating to the Exchange Offer (if the Exchange Offer is then
required to be made) or (iv) any Exchange Registration Statement or Shelf Registration Statement required by Section 2(a) or 2(b) hereof is filed and declared effective but shall thereafter either be withdrawn by the Company or shall
become subject to an effective stop order issued pursuant to Section 8(d) of the Securities Act suspending the effectiveness of such registration statement (except as specifically permitted herein) without being succeeded immediately by an
additional registration statement or post-effective amendment filed and declared effective (each such event referred to in clauses (i) through (iv), a “Registration Default” and each period during which a Registration Default has
occurred and is continuing, a “Registration Default Period”), then, as liquidated damages for such Registration Default, special interest (“Special Interest”), in addition to the Base Interest, shall accrue on the outstanding
Securities at a per annum rate of 0.25% for the first 90 days of the Registration Default Period, at a per annum rate of 0.50% for the second 90 days of the Registration Default Period, at a per annum rate of 0.75% for the third 90 days of the
Registration Default Period and at a per annum rate of 1.0% thereafter for the remaining portion of the Registration Default Period. 
 (d) The Company shall take, and shall cause each Guarantor to take, all actions necessary or advisable to be taken by it to ensure that the transactions contemplated herein are effected as so contemplated, including all actions necessary or
desirable to register the Guarantees under the registration statement contemplated in Section 2(a) or 2(b) hereof, as applicable. 
 (e) Any reference herein to a registration statement as of any time shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective
amendment to a registration statement as of any time shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time. 
 3. Registration Procedures. 
 If the Company files a
registration statement pursuant to Section 2(a) or Section 2(b), the following provisions shall apply: 
 (a) At or before the
Effective Time of the Exchange Offer or the Shelf Registration, as the case may be, the Company shall qualify the Indenture under the Trust Indenture Act. 
 (b) In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 

(c) In connection with the Company’s obligations with respect to the registration of Exchange Securities as contemplated by
Section 2(a) (the “Exchange Registration”), if applicable, the Company shall, as soon as practicable (or as otherwise specified): 
 (i) prepare and file with the Commission, as soon as practicable but no later than 90 days after the Closing Date, an Exchange Registration Statement on any form which may be utilized by the Company and which shall permit the
Exchange Offer and resales of Exchange Securities by broker-dealers during the Resale

broker-dealer holding Exchange Securities with such number of copies of the prospectus included therein (as then amended or supplemented), in conformity in all material respects with the requirements of the Securities Act and the Trust Indenture Act

respect to such Exchange Registration Statement or any post-effective amendment, when the same has become effective, (B) of any comments by the Commission and by the blue sky or securities commissioner or regulator of any state with respect
thereto or any request by the Commission for amendments or supplements to such Exchange Registration Statement or prospectus or for additional information, (C) of the issuance by the Commission of any stop order suspending the effectiveness of
such Exchange Registration Statement or the initiation or threatening of any proceedings for that purpose, (D) if at any time prior to consummation of the Exchange Offer the representations and warranties of the Company contemplated by
Section 5 cease to be true and correct in all material respects, (E) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Exchange Securities for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose, or (F) at any time during the Resale Period when a prospectus is required to be delivered under the Securities Act, that such Exchange Registration Statement, prospectus, prospectus
amendment or supplement or post-effective amendment does not conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder or contains an

underwriters may request at least two business days prior to any sale of the Registrable Securities; 
 (xv) provide a CUSIP number for
all Registrable Securities that are sold pursuant to the Shelf Registration Statement, not later than the applicable Effective Time, which CUSIP number shall be the same as the one used by the Company in connection with its outstanding 8% Series B

 (xvi) enter into one or
more underwriting agreements, engagement letters, agency agreements, “best efforts” underwriting agreements or similar agreements, as appropriate, including customary provisions relating to indemnification and contribution, and take such
other actions in connection therewith as any Electing Holders aggregating at least 20% in aggregate principal amount of the Registrable Securities at the time outstanding shall request in order to expedite or facilitate the disposition of such
Registrable Securities;

absence from such Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from the documents incorporated by reference therein (in each case other than the financial statements and other financial
information contained therein) of an untrue statement of a material fact or the omission to state therein a material fact necessary to make the statements therein not misleading (in the case of such documents, in the light of the circumstances

 (xix) in the event that any broker-dealer registered under the Exchange Act shall underwrite any Registrable Securities or
participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Conduct Rules) of the Financial Industry Regulatory Authority (“FINRA”) or
any successor thereto, as amended from time to time) thereof, whether as a holder of such Registrable Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, assist such broker-dealer in
complying with the requirements of such Conduct Rules, including by (A) if such Conduct Rules shall so require, engaging a “qualified independent underwriter” (as defined in such Conduct Rules) to participate in the preparation of the
Shelf Registration Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Shelf Registration Statement is an underwritten offering
or is made through a placement or sales agent, to recommend the yield of such Registrable Securities, (B) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 6

Securities Act (including, at the option of the Company, Rule 158 thereunder). 
 (e) In the event that the Company would be required,
pursuant to Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement or sales agent, if any, therefor and the managing underwriters, if any, thereof, the Company shall without delay prepare and furnish 

  

 14 

 
to each of the Electing Holders, to each placement or sales agent, if any, and to each such underwriter, if any, a reasonable number of copies of a prospectus
supplemented or amended so that, as thereafter delivered to purchasers of Registrable Securities, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules
and regulations of the Commission thereunder and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the
circumstances then existing. Each Electing Holder agrees that upon receipt of any notice from the Company pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder shall forthwith discontinue the disposition of Registrable Securities
pursuant to the Shelf Registration Statement applicable to such Registrable Securities until such Electing Holder shall have received copies of such amended or supplemented prospectus, and if so directed by the Company, such Electing Holder shall
deliver to the Company (at the Company’s expense) all copies, other than permanent file copies which shall not be distributed, then in such Electing Holder’s possession of the prospectus covering such Registrable Securities at the time of
receipt of such notice. 
 (f) In the event of a Shelf Registration, in addition to the information required to be provided by each
Electing Holder in its Notice and Questionnaire, the Company may require such Electing Holder to furnish to the Company such additional information regarding such Electing Holder and such Electing Holder’s intended method of distribution of
Registrable Securities as may be required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Electing
Holder to the Company or of the occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an untrue statement of a material fact regarding such Electing Holder or such
Electing Holder’s intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities
required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any additional information required to correct and update any previously
furnished information or required so that such prospectus shall not contain, with respect to such Electing Holder or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. 
 (g) The
Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Securities that have been acquired by any of them, except for Securities purchased by the Company or any of its
affiliates and resold in a transaction registered under the Securities Act. 
 4. Registration Expenses. 
 The Company agrees to bear and to pay or cause to be paid promptly all expenses incident to the Company’s performance of or compliance with this Exchange and
Registration Rights Agreement, including (a) all Commission and any FINRA registration, filing and review fees and expenses including fees and disbursements of counsel for the placement or sales agent or underwriters in connection with such

persons, including special experts, retained by the Company in connection with such registration (collectively, the “Registration Expenses”). To the extent that any Registration Expenses are incurred, assumed or paid by any holder of
Registrable Securities or any placement or sales agent therefor or underwriter thereof, the Company shall reimburse such person for the full amount of the Registration Expenses so incurred, assumed or paid promptly after receipt of a request
therefor. Notwithstanding the foregoing, the holders of the Registrable Securities being registered shall pay all agency fees and commissions and underwriting discounts and commissions attributable to the sale of such Registrable Securities and the
fees and disbursements of any counsel or other advisors or experts retained by such holders (severally or jointly), other than the counsel and experts specifically referred to above. 
 5. Representations and Warranties. 
 The Company
represents and warrants to, and agrees with, each Purchaser and each of the holders from time to time of Registrable Securities that: 
 (a) Each registration statement covering Registrable Securities and each prospectus (including any preliminary or summary prospectus) contained therein or furnished pursuant to Section 3(c) or Section 3(d) hereof and any further
amendments or supplements to any such registration statement or prospectus, when it becomes effective or is filed with the Commission, as the case may be, and, in the case of an underwritten offering of Registrable Securities, at the time of the
closing under the underwriting agreement relating thereto, will conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and at all times 

  

 16 

 
subsequent to the Effective Time when a prospectus would be required to be delivered under the Securities Act, other than from (i) such time as a notice has been
given to holders of Registrable Securities pursuant to Section 3(c)(iii)(F) or Section 3(d)(viii)(F) hereof until (ii) such time as the Company furnishes an amended or supplemented prospectus pursuant to Section 3(c)(iv) or
Section 3(e) hereof, each such registration statement, and each prospectus (including any summary prospectus) contained therein or furnished pursuant to Section 3(c) or Section 3(d) hereof, as then amended or supplemented, will
conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided, however, that this representation and warranty shall not apply to any statements or
omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 
 (b) Any documents incorporated by reference in any prospectus referred to in Section 5(a) hereof, when they become or became effective or are
or were filed with the Commission, as the case may be, will conform or conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and none of such documents will contain or contained an untrue
statement of a material fact or will omit or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and warranty shall not apply
to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 
 (c) The compliance by the Company with all of the provisions of this Exchange and Registration Rights Agreement and the consummation of the
transactions herein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the
Company or any subsidiary of the Company is a party or by which the Company or any subsidiary of the Company is bound or to which any of the property or assets of the Company or any subsidiary of the Company is subject, other than any such conflict,
breach or default that, individually or in the aggregate, would not have a Material Adverse Effect (as such term is defined in the Purchase Agreement); nor will such action result in any violation of the provisions of the certificate of
incorporation, by-laws or other organizational document of the Company or any Guarantor; nor will such action result in any violation of any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction
over the Company or any subsidiary of the Company or any of their properties, other than any such violation that, individually or in the aggregate, would not have a Material Adverse Effect; and no consent, approval, authorization, order,
registration or qualification of or with any such court or governmental agency or body is required for the consummation by the Company and the Guarantors of the transactions contemplated by this Exchange and Registration Rights Agreement, except the
registration under the Securities Act of the Securities and the declaration of the effectiveness of any related registration statement, qualification of the Indenture under the Trust Indenture Act and such consents, approvals, authorizations,

 17 

 (d) This Exchange and Registration Rights Agreement has been duly authorized, executed and
delivered by the Company and the Guarantors. 
 6. Indemnification. 
 (a) Indemnification by the Company and the Guarantors. The Company and the Guarantors, jointly and severally, will indemnify and hold
harmless each of the holders of Registrable Securities included in an Exchange Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who participates as a placement
or sales agent or as an underwriter in any offering or sale of such Registrable Securities against any losses, claims, damages or liabilities, joint or several, to which such holder, agent or underwriter may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Exchange Registration Statement
or Shelf Registration Statement, as the case may be, under which such Registrable Securities were registered under the Securities Act, or any preliminary, final or summary prospectus contained therein or furnished by the Company to any such holder,
Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse such holder, such Electing Holder, such agent and such underwriter for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that neither the Company nor any Guarantor shall be liable to any such person in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus, or amendment or supplement thereto, in reliance upon and in conformity with written information
furnished to the Company by such person expressly for use therein. 
 (b) Indemnification by the Holders and any Agents and
Underwriters. The Company may require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the
Company shall have received an undertaking reasonably satisfactory to it from the Electing Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and
hold harmless the Company, the Guarantors, and all other holders of Registrable Securities, against any losses, claims, damages or liabilities to which the Company, the Guarantors or such other holders of Registrable Securities may become subject,
under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such
registration statement, or any preliminary, final or summary prospectus contained therein or furnished by the Company to any such Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Electing Holder or underwriter expressly for use therein, and (ii) reimburse the 

  

 18 

 
Company and the Guarantors for any legal or other expenses reasonably incurred by the Company and the Guarantors in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that no such Electing Holder shall be required to undertake liability to any person under this Section 6(b) for any amounts in excess of the dollar amount of the proceeds
to be received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such registration. 
 (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof
is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such indemnifying party in writing of the commencement of such action; provided that the failure to
notify the indemnifying party shall not relieve it from any liability that it may have under Sections 6(a) or 6(b) above 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 party shall not relieve it from any liability that it may have to an indemnified party otherwise than under Sections 6(a) or 6(b) hereof. If any such proceeding shall
be brought or asserted against an indemnified party and it shall have notified the indemnifying party thereof, the indemnifying party shall retain counsel reasonably satisfactory to the indemnified party (who shall not, without the consent of the
indemnified party, be counsel to the indemnifying party) to represent the indemnified party and any others entitled to indemnification pursuant to this Section 6 that the indemnifying party may designate in such proceeding and shall pay the
fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. 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 contrary; (ii) the indemnifying party has failed within a reasonable time to
retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party 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 party; or (iv) the named parties in 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 and agreed that the indemnifying party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all indemnified parties, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Purchaser, its affiliates, directors and
officers and any control persons of such Purchaser shall be designated in writing by J.P. Morgan Securities Inc. and any such separate firm for the Company, the Guarantors, their respective directors and officers and any control persons of the
Company and the Guarantors shall be designated in writing by the Company. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect
to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure
to act by or on behalf of any indemnified party. 
  

 19 

 (d) Contribution. If for any reason the indemnification provisions contemplated by
Section 6(a) or Section 6(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying
party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the
indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The
relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact
relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto
agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the holders or any agents or underwriters or all of them were treated as one entity for such purpose)
or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, or liabilities (or
actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no holder shall be required to contribute any amount in excess of the amount by which the dollar amount of the proceeds received by such holder from the sale of any Registrable Securities (after deducting any
fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall
be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such
underwriter 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’ and any underwriters’ obligations in this Section 6(d) to contribute shall be several in proportion to the
principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint. 
 (e) The obligations
of the Company and the Guarantors under this Section 6 shall be in addition to any liability which the Company or the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of
each holder, agent and underwriter and each person, if any, who controls any holder, agent or underwriter within the meaning of the Securities Act; and the obligations of the holders and any agents or underwriters contemplated by this Section 6
shall be in addition to any liability which the respective holder, agent or underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company or any Guarantor (including any person who,
with his consent, is named in any registration statement as about to become a director of the Company or any Guarantor) and to each person, if any, who controls the Company within the meaning of the Securities Act. 
  

 20 

 7. Underwritten Offerings. 
 (a) Selection of Underwriters. If any of the Registrable Securities covered by the Shelf Registration are to be sold pursuant to an
underwritten offering, the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities to be included in such offering, provided that
such designated managing underwriter or underwriters is or are reasonably acceptable to the Company. 
 (b) Participation by
Holders. Each holder of Registrable Securities hereby agrees with each other such holder that no such holder may participate in any underwritten offering hereunder unless such holder (i) agrees to sell such holder’s Registrable
Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such underwriting arrangements. 
 8. Rule 144. 
 The Company covenants to the holders of Registrable Securities that to the extent it shall be required to do so under the Exchange Act, the Company shall timely
file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Section 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission under the
Securities Act) and the rules and regulations adopted by the Commission thereunder, and shall take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder
to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144 under the Securities Act, as such Rule may be amended from time to time, or any similar or successor rule or
regulation hereafter adopted by the Commission. Upon the request of any holder of Registrable Securities in connection with that holder’s sale pursuant to Rule 144, the Company shall deliver to such holder a written statement as to whether
it has complied with such requirements. 
 9. Miscellaneous. 
 (a) No Inconsistent Agreements. The Company represents, warrants, covenants and agrees that it has not granted, and shall not grant,
registration rights with respect to Registrable Securities or any other securities which would be inconsistent with the terms contained in this Exchange and Registration Rights Agreement. 
 (b) Specific Performance. The parties hereto acknowledge that, except as provided in Section 2(c) hereof in relation to a Registration
Default, there would be no adequate remedy at law if the Company fails to perform any of its obligations hereunder and that the Purchasers and the holders from time to time of the Registrable Securities may be irreparably harmed by any such failure,
and accordingly agree that the Purchasers and such holders, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of the Company under this Exchange and
Registration Rights Agreement in accordance with the terms and conditions of this Exchange and Registration Rights Agreement, in any court of the United States or any State thereof having jurisdiction. 
  

 21 

 (c) Notices. All notices, requests, claims, demands, waivers and other communications
hereunder shall be in writing and shall be deemed to have been duly given when delivered by hand, if delivered personally or by courier, or three days after being deposited in the mail (registered or certified mail, postage prepaid, return receipt
requested) as follows: If to the Company, to it at 103 Northpark Boulevard, Suite 300, Covington, Louisiana 70433 and if to a holder, to the address of such holder set forth in the security register or other records of the Company, or to such other

No Stabilization. Neither the Company nor any of the Guarantors will take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the
Securities. 
 5. Certain Agreements of the Initial Purchasers. Each Initial Purchaser hereby represents and agrees that it has not and will not
use, authorize use of, refer to, or participate in the planning for use of, any written communication that constitutes an offer to sell or the solicitation of an offer to buy the Securities other than (i) the Preliminary Offering Memorandum and
the Offering Memorandum, (ii) a written communication that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including through incorporation by reference) 

  

 18 

 
in the Preliminary Offering Memorandum or the Offering Memorandum, (iii) any written communication listed on Annex A or prepared pursuant to Section 4(c)
above (including any electronic road show), (iv) any written communication prepared by such Initial Purchaser and approved by the Company in advance in writing or (v) any written communication relating to or that contains the terms of the
Securities and/or other information that was included (including through incorporation by reference) in the Preliminary Offering Memorandum or the Offering Memorandum. 
 6. Conditions of Initial Purchasers’ Obligations. The obligation of each Initial Purchaser to purchase Securities on the Closing Date as provided herein is subject to the performance by the Company and each of the
Guarantors of their respective covenants and other obligations hereunder and to the following additional conditions: 
 (a) Representations and
Warranties. The representations and warranties of the Company and the Guarantors contained herein shall be true and correct on the date hereof and on and as of the Closing Date; and the statements of the Company, the Guarantors and their
respective officers made in any certificates delivered pursuant to this Agreement shall be true and correct on and as of the Closing Date. 
 (b) No
Downgrade. Subsequent to the earlier of (A) the Time of Sale and (B) the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded the Securities or any other debt securities or
preferred stock issued or guaranteed by the Company or any of its subsidiaries by any “nationally recognized statistical rating organization”, as such term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities
Act; and (ii) no such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its rating of the Securities or of any other debt securities or preferred stock issued or
guaranteed by the Company or any of its subsidiaries (other than an announcement with positive implications of a possible upgrading). 
 (c) No
Material Adverse Change. No event or condition of a type described in Section 3(e) hereof shall have occurred or shall exist, which event or condition is not described in each of the Time of Sale Information (excluding any amendment or
supplement thereto) and the Offering Memorandum (excluding any amendment or supplement thereto) the effect of which in the judgment of the Representative makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the
Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum. 
 (d)
Officer’s Certificate. The Representative shall have received on and as of the Closing Date a certificate of an executive officer of the Company and of each Guarantor who has specific knowledge of the Company’s or such
Guarantor’s financial matters and is satisfactory to the Representative (i) confirming that such officer has carefully reviewed the Time of Sale Information and the Offering Memorandum and, to 

  

 19 

 
the best knowledge of such officer, the representations set forth in Sections 3(a) and 3(b) hereof are true and correct, (ii) confirming that the other
representations and warranties of the Company and the Guarantors in this Agreement are true and correct and that the Company and the Guarantors have complied with all agreements and satisfied all conditions on their part to be performed or satisfied
hereunder at or prior to the Closing Date and (iii) to the effect set forth in paragraphs (b) and (c) above. 
 (e) Comfort
Letters. On the date of this Agreement and on the Closing Date, Ernst & Young LLP shall have furnished to the Representative, at the request of the Company, letters, dated the respective dates of delivery thereof and addressed to the
Initial Purchasers, in form and substance reasonably satisfactory to the Representative, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the
financial statements and certain financial information contained or incorporated by reference in each of the Time of Sale Information and the Offering Memorandum; provided that the letter delivered on the Closing Date shall use a
“cut-off” date no more than three business days prior to the Closing Date.

Representative, to the effect set forth in Annex D hereto. 
 (g) Opinion of Counsel for the Initial Purchasers. The Representative shall have
received on and as of the Closing Date an opinion of Vinson & Elkins LLP, counsel for the Initial Purchasers, with respect to such matters as the Representative may reasonably request, and such counsel shall have received such documents and
information as they may reasonably request to enable them to pass upon such matters. 
 (h) No Legal Impediment to Issuance. No action shall
have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date, prevent the issuance or sale of the

Guarantees. 
 (i) Good Standing. The Representative shall have received on and as of the Closing Date satisfactory evidence of the good
standing of the Company and its subsidiaries in their respective jurisdictions of organization and their good standing in such other jurisdictions as the Representative may reasonably request, in each case in writing or any standard form of
telecommunication, from the appropriate governmental authorities of such jurisdictions. 
  

 20

Registration Rights Agreement that shall have been executed and delivered by a duly authorized officer of the Company and each of the Guarantors. 
 (k) DTC. The Securities shall be eligible for clearance and settlement through DTC. 
 (l) Additional Documents. On or prior to
the Closing Date, the Company and the Guarantors shall have furnished to the Representative such further certificates and documents as the Representative may reasonably request. 
 All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only
if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers. 
 7. Indemnification and Contribution.

 (a) Indemnification of the Initial Purchasers. The Company and each of the Guarantors jointly and severally agree to indemnify and hold
harmless each Initial Purchaser, its affiliates, directors and officers and each person, if any, who controls such Initial Purchaser 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 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 upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the
Offering Memorandum (or any amendment or supplement thereto) 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 any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use therein. 
 (b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, each of their respective directors and officers and each
person, if any, who controls the Company or any of the Guarantors 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 

  

 21 

 
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 Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer
Written Communication or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the following: the third and twelfth paragraphs under the caption “Plan of
distribution” in the Offering Memorandum. 
 (c) Notice and Procedures. 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 paragraphs (a) or (b) above 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 paragraphs (a) or (b) above. 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 (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying
Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such 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 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 for any Initial Purchaser, its 

  

 22 

 
affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by J.P. Morgan Securities Inc. and any such
separate firm for the Company, the Guarantors, their respective directors and officers and any control persons of the Company and the Guarantors 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
(x) 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 (y) 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)
Contribution. 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 on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in 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
Initial Purchasers on the other 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 benefits received by the Company and
the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total
discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of 

  

 23 

 
the Company and the Guarantors on the one hand and the Initial Purchasers on the other 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 any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. 
 (e) Limitation on Liability. The Company, the
Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers 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 incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding
the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering
of the Securities exceeds the amount of any damages that such Initial Purchaser 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 Initial Purchasers’ obligations to contribute pursuant to this
Section 7 are several in proportion to their respective purchase obligations hereunder and not joint. 
 (f) Non-Exclusive Remedies. The
remedies provided for in this Section 7 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. 
 8. Termination. This Agreement may be terminated in the reasonable discretion of the Representative, by notice to the Company, if after the execution and
delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or
guaranteed by the Company or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State
authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is
material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery, of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

  

 24 

 9. Defaulting Initial Purchaser. (a) If, on the Closing Date, any Initial Purchaser defaults on its
obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms
contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36
hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser,
either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be
necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that
effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this
Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase. 
 (b) If, after giving effect to any
arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such
Securities that remains unpurchased does not exceed one-tenth of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of
Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the
Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made. 
 (c) If, after giving effect to
any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such
Securities that remains unpurchased exceeds one-tenth of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without
liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the
Guarantors will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect. 
  

 25 

 (d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the
Company, the Guarantors or any non-defaulting Initial Purchaser for damages caused by its default. 
 10. Payment of Expenses.
(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to
the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection;
(ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto) and
the distribution thereof; (iii) the costs of reproducing and distributing this Agreement, the Indenture, the Registration Rights Agreement and the Global Notes; (iv) the fees and expenses of the Company’s and the Guarantors’
counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the
Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the
Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the
Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors. 
 (b) If (i) this Agreement is terminated pursuant to Section 8(ii), (ii) the Company for any reason fails to tender the Securities for delivery to
the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement (other than pursuant to Section 8(i), (iii), or (iv)), the Company and each of the Guarantors jointly
and severally agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering
contemplated hereby. 
 11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Initial Purchaser referred to in Section 7 hereof. Nothing in this Agreement is intended or shall
be construed to give any other person any legal or equitable right, 

  

 26 

 
remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a
successor merely by reason of such purchase. 
 12. Survival. The respective indemnities, rights of contribution, representations, warranties
and agreements of the Company, the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant
hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination or completion of this Agreement or any investigation made by or on behalf of the Company, the Guarantors or
the Initial Purchasers. 
 13. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the
term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the
term “Exchange Act” means the Securities Exchange Act of 1934, as amended; (d) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (e) the term “written communication” has
the meaning set forth in Rule 405 under the Securities Act. 
 14. Miscellaneous. (a) Authority of the Representative. Any action by
the Initial Purchasers hereunder may be taken by J.P. Morgan Securities Inc. on behalf of the Initial Purchasers, and any such action taken by J.P. Morgan Securities Inc. shall be binding upon the Initial Purchasers. 
 (b) Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and
confirmed by any standard form of telecommunication. Notices to the Initial Purchasers shall be given to the Representative c/o J.P. Morgan Securities Inc., 270 Park Avenue, New York, New York 10017 (fax: (212)-270-1063); Attention: Lawrence Landry.

 (c) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York. 
 (d) Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of
which shall be an original and all of which together shall constitute one and the same instrument. 
  

 27 

 (e) Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or
approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto. 
 (f)
Headings. The headings herein are included for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

other financial or accounting data included in, or excluded from, the Time of Sale Information or the Offering Memorandum as to which such counsel need express no belief) that the Time of Sale Information, at the Time of Sale (which such counsel may
assume to be the date of this Agreement), contained any untrue statement of a material fact or omitted to state a material fact or necessary to make the statements therein, in the light of the circumstances under which they were made, not
misleading, or that the Offering Memorandum or any amendment or supplement thereto, as of its date and the Closing Date, contained or contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not misleading (other than, in each case, the financial statements and other financial information contained or incorporated by reference therein, as to which such counsel need
express no belief). 
 In rendering such opinion, such counsel may rely as to matters of fact on certificates of responsible officers of the Company
and the Guarantors and public officials that are furnished to the Initial Purchasers. 
 The opinion of Winstead PC described above shall be rendered
to the Initial Purchasers at the request of the Company and shall so state therein.
