nor any Guarantor will make any offer to sell or solicitation of an offer to buy the Notes that would constitute a Free Writing Offering Document without the prior consent of the Representative, which consent shall not be unreasonably withheld or
delayed. If at any time following issuance of a Free Writing Offering Document any event occurred or occurs as a result of which such Free Writing Offering Document conflicts with the information in the Preliminary Offering Memorandum, the Pricing
Disclosure Package 

  
 22 








 
or the Offering Memorandum or, when taken together with the information in the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, includes an untrue
statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, as promptly as practicable after becoming aware thereof, the
Company will give notice thereof to the Initial Purchasers through the Representative and, if requested by the Representative, will prepare and furnish without charge to each Initial Purchaser a Free Writing Offering Document or other document which
will correct such conflict, statement or omission. 
 (f) Promptly from time to time to take such action as the Initial
Purchasers may reasonably request to qualify the Notes for offering and sale under the securities or Blue Sky laws of such jurisdictions as the Initial Purchasers may request and to comply with such laws so as to permit the continuance of sales and
dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Notes; provided that in connection therewith the Company shall not be required to (i) qualify as a foreign corporation in any
jurisdiction in which it would not otherwise be required to so qualify, (ii) file a general consent to service of process in any such jurisdiction, or (iii) subject itself to taxation in any jurisdiction in which it would not otherwise be
subject. 
 (g) For a period commencing on the date hereof and ending on the 90th day after the date of the Offering Memorandum, the Company and the
Guarantors agree not to, directly or indirectly, (i) offer for sale, sell, or otherwise dispose of (or enter into any transaction or device that is designed to, or would be expected to, result in the disposition by any person at any time in the
future of) any debt securities of the Company substantially similar to the Notes or securities convertible into or exchangeable for such debt securities of the Company, or sell or grant options, rights or warrants with respect to such debt
securities of the Company or securities convertible into or exchangeable for such debt securities of the Company, (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic
benefits or risks of ownership of such debt securities of the Company, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of debt securities of the Company or other securities, in cash or
otherwise, (iii) file or cause to be filed a registration statement, including any amendments, with respect to the registration of debt securities of the Company substantially similar to the Notes or securities convertible, exercisable or
exchangeable into debt securities of the Company substantially similar to the Notes, or (iv) publicly announce an offering of any debt securities of the Company substantially similar to the Notes or securities convertible or exchangeable into
debt securities substantially similar to the Notes, in each case without the prior written consent of Wells Fargo Securities, LLC, on behalf of the Initial Purchasers, except in exchange for the Exchange Notes and the Exchange Guarantees in
connection with the Exchange Offer. 
 (h) Upon request, so long as any of the Notes are outstanding, the Company and the
Guarantors will, furnish at their expense to the Initial Purchasers and to the holders of the Notes the information required by Rule 144A(d)(4) under the Securities Act (if any). 

(i) The Company and the Guarantors will apply the net proceeds from the sale of the Notes to be sold by it hereunder substantially in
accordance with the description set forth in the Pricing Disclosure Package and the Offering Memorandum under the caption “Use of Proceeds.” 

  
 23 








 (j) The Company, the Guarantors and their respective affiliates will not take, directly or
indirectly, any action designed to or that has constituted or that reasonably could be expected to cause or result in the stabilization or manipulation of the price of any security of the Company or the Guarantors in connection with the offering of
the Notes. 
 (k) The Company and the Guarantors will use their best efforts to permit the Notes to be eligible for clearance
and settlement through DTC.

transaction registered under the Securities Act. 
 (m) The Company and the Guarantors will take precautions designed to insure
that any offer or sale, direct or indirect, in the United States or to any U.S. person (as defined in Rule 902 under the Securities Act), of any Notes or any substantially similar security issued by the Company or any Guarantor, within six months
subsequent to the date on which the distribution of the Notes has been completed (as notified to the Company by the Initial Purchasers), is made under restrictions and other circumstances reasonably designed not to affect the status of the offer and
sale of the Notes in the United States and to U.S. persons contemplated by this Agreement as transactions exempt from the registration provisions of the Securities Act, including any sales pursuant to Rule 144A under, or Regulations D or S of, the
Securities Act. 
 (n) None of the Company or any of the Guarantors or any other person on its or their behalf (other than the
Initial Purchasers, as to which no covenant is given) will (i) solicit offers for, or offer or sell, the Notes by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any

in all material respects the conclusions and findings set forth in the initial letter. 
 (h) Except as described in the Pricing

reference in the Pricing Disclosure Package and the Offering Memorandum, any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or
governmental action, order or decree, or (ii) since such date, there shall not have been any change in the capital stock or long-term debt of the Company, any Guarantor or any of their respective subsidiaries or any change, or any development
involving a prospective change, in or affecting the business, properties, prospects, financial condition, stockholders’ equity or results of operations of the Company, the Guarantors and their respective subsidiaries, taken as a whole, the
effect of which, in any such case described in clause (i) or (ii), is, individually or in the aggregate, in the judgment of the Representative, so material and adverse as to make it impracticable or inadvisable to proceed with the offering or
the delivery of the Notes being delivered on the Closing Date on the terms and in the manner contemplated in the Pricing Disclosure Package and the Offering Memorandum. 
 (i) At the time of execution of this Agreement, the Initial Purchasers shall have received from each of (a) Forrest A. Garb & Associates, (b) Cawley Gillespie & Associates,

a subsequent letter dated as of the Closing Date, which such letter shall cover the period from any initial expert letter to the Closing Date, confirming that they are independent with respect to the Company and stating the conclusions and findings

Associates, Inc., and the Company’s use of the estimates of proved reserves from W.D. Von Gonten & Co. for the Williston Basin Assets, as is customary to initial purchasers in connection with similar transactions. 

(j) The Company and each Guarantor shall have furnished or caused to be furnished to the Initial Purchasers dated as of the Closing Date
a certificate of the Chief Executive Officer and Chief Financial Officer of the Company and each Guarantor, or other officers satisfactory to the Initial Purchasers, as to such matters as the Representative may reasonably request, including, without
limitation, a statement that: 
  

	 	(i)	The representations, warranties and agreements of the Company and the Guarantors in Section 2 are true and correct on and as of the Closing Date, and the Company
and the Guarantors have complied with all its agreements contained herein and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and 


  
 27 









	 	(ii)	They have examined the Pricing Disclosure Package and the Offering Memorandum, and, in their opinion, (A) the Pricing Disclosure Package, as of the Applicable Time
and as of the Closing Date, and the Offering Memorandum, as of its date and as of the Closing Date, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading and (B) since the date of the Pricing Disclosure Package and the Offering Memorandum, no event has occurred which should have been set forth in a
supplement or amendment to the Pricing Disclosure Package and the Offering Memorandum. 

 (k) Subsequent to the
earlier of the Applicable Time and the execution and delivery of this Agreement (i) no downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating
organization,” as such term is used in Section 15E of the Exchange 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 Notes or of any other debt securities issued or guaranteed by the Company or any of the Guarantors (in each case, other than an announcement with positive implications of a possible upgrading); provided, however, that this
Section 7(k) shall not apply to the announcement by Moody’s Investors Service, Inc. on January 9, 2012 of its initiation of a review of the Company’s debt securities. 

(l) The Notes shall be eligible for clearance and settlement through DTC. 

(m) The Company and the Guarantors shall have executed and delivered the Registration Rights Agreement, and the Initial Purchasers shall
have received an original copy thereof, duly executed by the Company and the Guarantors. 
 (n) Subsequent to the execution and
delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the NYSE Amex Equities or in the over-the-counter market, or trading in any securities of the
Company on any exchange or in the over-the-counter market, shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such
exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a general moratorium on commercial banking activities shall have been declared by federal or state
authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United
States, (iv) a material disruption in commercial banking or securities settlement or clearance services in the United States, or (v) there shall have occurred such a material adverse change in general economic, political or financial
conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial 

  
 28 








 
markets in the United States shall be such), as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the offering or delivery of the Notes being
delivered on the Closing Date on the terms and in the manner contemplated in the Pricing Disclosure Package and the Offering Memorandum or that, in the judgment of the Representative, could materially and adversely affect the financial markets or
the markets for the Notes and other debt securities. 
 (o) There shall exist at and as of the Closing Date no condition that:
(i) would constitute a default (or an event that with notice or the lapse of time, or both, would constitute a default) under the Indenture or (ii) a breach under the Purchase and Sale Agreement as in effect at the Closing Date (or an
event that with notice or lapse of time, or both, would constitute such a breach) excluding for purposes of (ii) any breach or prospective breach of the Purchase and Sale Agreement that would not reasonably be expected to have a Pro Forma
Material Adverse Effect. 
 (p) The Notes and the notation of guarantees shall be executed by the Company and the Guarantors in
substantially the respective forms set forth in the Indenture and the Notes shall be authenticated and delivered by the Trustee in accordance with Section 2.2 of the Indenture. 

All opinions, letters, evidence and certificates 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. 

8. Indemnification and Contribution. 
 (a) The Company and each Guarantor, hereby agrees, jointly and severally, to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees and each person, if any,
who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which that Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering
Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by the Company or any
Guarantor (or based upon any written information furnished by the Company or any Guarantor) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application,
document or information being hereinafter called a “Blue Sky Application”), or (C) in any materials or information provided to investors by, or with the approval of, the Company or any Guarantor in connection with the
marketing of the offering of the Notes (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically) or any materials prepared for the
purpose of compliance with the Canadian securities laws, or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing


  
 29 








 
Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, any material fact necessary in order to
make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person promptly upon demand for
any legal or other expenses reasonably incurred by that Initial Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage,
liability or action as such expenses are incurred; provided, however, that the Company and the Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is
based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Disclosure Package or Offering Memorandum, or in any such amendment or supplement thereto, or in
any Blue Sky Application or in any Marketing Materials, in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company through the Representative by or on behalf of any Initial Purchaser
specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Company or the Guarantors may otherwise have to any
Initial Purchaser or to any affiliate, director, officer, employee or controlling person of that Initial Purchaser. 
 (b) Each
Initial Purchaser, severally and not jointly, hereby agrees to indemnify and hold harmless the Company, each Guarantor, their respective officers and employees, each of their respective directors, and each person, if any, who controls the Company or
any Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, any
Guarantor or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue
statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto,
(B) in any Blue Sky Application, or (C) in any Marketing Materials, or (ii) the omission or alleged omission to state in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the
Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were
made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser
furnished to the Company through the Representative by or on behalf of that Initial Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in
addition to any liability that any Initial Purchaser may otherwise have to the Company, any Guarantor or any such director, officer, employee or controlling person. 
 (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party under this Section 8, notify the 

  
 30 








 
indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any
liability that it may have under this Section 8 except to the extent 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 this paragraph (a) or (b) of this Section 8. If any such claim or action shall be brought against an
indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the
defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided,
however, that the Initial Purchasers shall have the right to employ counsel to represent jointly the Initial Purchasers and their respective affiliates, directors, officers, employees and controlling persons who may be subject to liability
arising out of any claim in respect of which indemnity may be sought by the Initial Purchasers against the Company or any Guarantor under this Section 8, if (i) the Company, the Guarantors and the Initial Purchasers shall have so mutually
agreed; (ii) the Company and the Guarantors have failed within a reasonable time to retain counsel reasonably satisfactory to the Initial Purchasers; (iii) the Initial Purchasers and their respective affiliates, directors, officers,
employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the Company and the Guarantors; or
(iv) the named parties in any such proceeding (including any impleaded parties) include both the Initial Purchasers or their respective affiliates, directors, officers, employees or controlling persons, on the one hand, and the Company and the
Guarantors, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel
shall be paid by the Company and the Guarantors. No indemnifying party shall (x) without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or
threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement,
compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying
party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

 (d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold
harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified
party, 

  
 31 








 
contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be
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 Notes, or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors, on the one hand, and the Initial
Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, 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, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement
(before deducting expenses) received by the Company and the Guarantors, on the one hand, and the total discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bear to
the total gross proceeds from the offering of the Notes under this Agreement as set forth on the cover page of the Offering Memorandum. The relative fault shall be determined by reference to 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 the Company, the Guarantors, or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Company shall be deemed to be also for the benefit of the Guarantors, and information supplied
by the Company shall also be deemed to have been supplied by the Guarantors. The Company, the Guarantors, and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be
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 into account the equitable considerations referred to herein. The amount paid or
payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other
expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Initial Purchaser shall be required to contribute any amount
in excess of the amount by which the net proceeds from the sale to Eligible Purchasers of the Notes initially purchased by it exceeds the amount of any damages that such Initial Purchaser has otherwise paid or become liable to pay by reason of any
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 as provided in this Section 8(d) are several in proportion to their respective purchase obligations and not joint. 

(e) The Initial Purchasers severally confirm and the Company and the Guarantors acknowledge and agree that the statements contained in
the second sentence under the heading “Plan of Distribution—Rule 144A and Regulation S” in the Pricing Disclosure Package and the Offering Memorandum are correct and constitute the only information concerning such Initial Purchasers
furnished in writing to the Company or any Guarantor by or on behalf of the Initial Purchasers specifically for inclusion in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package, the Offering
Memorandum, or in any amendment or supplement thereto or in any Blue Sky Application or in any Marketing Materials.

 9. Defaulting Initial Purchasers. 

(a) If, on the Closing Date, any Initial Purchaser defaults in its obligations to purchase the Notes that it has agreed to purchase under
this Agreement, the remaining non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Notes by the non-defaulting Initial Purchasers or 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 Notes, 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 Notes on such terms. In the event that within the respective prescribed periods, the non-defaulting Initial Purchasers notify the Company that they have so
arranged for the purchase of such Notes, or the Company notifies the non-defaulting Initial Purchasers that it has so arranged for the purchase of such Notes, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date
for up to seven 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 Pricing Disclosure Package, the Offering Memorandum or in any other
document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Pricing Disclosure Package 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 requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 9, purchases Notes that a defaulting Initial Purchaser agreed but
failed to purchase. 
 (b) If, after giving effect to any arrangements for the purchase of the Notes 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 Notes that remains unpurchased does not exceed one-eleventh of the aggregate
principal amount of all the Notes, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Notes that such Initial Purchaser agreed to purchase hereunder plus such Initial
Purchaser’s pro rata share (based on the principal amount of Notes that such Initial Purchaser agreed to purchase hereunder) of the Notes of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have
not been made; provided that the non-defaulting Initial Purchasers shall not be obligated to purchase more than 110% of the aggregate principal amount of Notes that it agreed to purchase on the Closing Date pursuant to the terms of
Section 3. 
 (c) If, after giving effect to any arrangements for the purchase of the Notes 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 Notes that remains unpurchased exceeds one-eleventh of the aggregate principal
amount of all the Notes, 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 

  
 33 








 
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 Sections 6 and 11 to the
non-defaulting Initial Purchasers and except that the provisions of Section 8 shall not terminate and shall remain in effect. 
 (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. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial
Purchasers by notice given to and received by the Company prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(h), (i), (l) or (q) shall have occurred or if the Initial Purchasers
shall decline to purchase the Notes for any other reason permitted under this Agreement. 
 11. Reimbursement of Initial
Purchasers’ Expenses. If (a) the Company for any reason fails to tender the Notes for delivery to the Initial Purchasers, or (b) the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this
Agreement, the Company and the Guarantors shall jointly and severally reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Initial Purchasers) incurred by the Initial
Purchasers in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Company and the Guarantors shall pay the full amount thereof to the Initial Purchasers. If this Agreement is terminated pursuant to
Section 9 by reason of the default of one or more Initial Purchasers, the Company and the Guarantors shall not be obligated to reimburse any defaulting Initial Purchaser on account of those expenses. 

12. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and: 

(a) if to any Initial Purchasers, shall be delivered or sent by hand delivery, mail, telex, overnight courier or facsimile transmission to

This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that the representations, warranties, indemnities and agreements of the Company and the Guarantors contained in this Agreement shall also be
deemed to be for the benefit of the affiliates, directors, officers and employees of the Initial Purchasers and each person or persons, if any, controlling any Initial Purchaser within the meaning of Section 15 of the Securities Act. Nothing in
this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 13, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

 14. 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 them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Notes and shall remain in full force and
effect, regardless of any termination of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them. 
 15. Definition of the Terms “Business Day”, “Affiliate”, and “Subsidiary”. For purposes of this Agreement, (a) “business day” means any day on which the
New York Stock Exchange, Inc. is open for trading, and (b) “affiliate” and “subsidiary” have the meanings set forth in Rule 405 under the Securities Act. 

16. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

 17. Waiver of Jury Trial. The Company and each of the Initial Purchasers hereby irrevocably waives, to the fullest

18. No Fiduciary Duty. The Company and the Guarantors acknowledge and agree that in connection with this offering, or any other
services the Initial Purchasers may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the
Initial Purchasers: (a) no fiduciary or agency relationship between the Company, any Guarantor and any other person, on the one hand, and the Initial Purchasers, on the other, exists; 

  
 35 








 
(b) the Initial Purchasers are not acting as advisors, expert or otherwise, to the Company or the Guarantors, including, without limitation, with respect to the determination of the purchase
price of the Notes, and such relationship between the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations
