Introductory. Continental Resources, Inc., an Oklahoma corporation (the “Company”), proposes to issue and sell to the several Initial Purchasers named in Schedule A (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $400,000,000 aggregate principal amount of the Company’s 7  ¹/8% Senior Notes due 2021 (the “Notes”). Banc of America Securities LLC, J.P. Morgan Securities LLC and RBS Securities Inc. have agreed to act as the representatives of the several Initial Purchasers (the “Representatives”) in connection with the offering and sale of the Notes.

The Notes will be issued pursuant to an indenture, to be dated as of September 16, 2010 (the “Indenture”), among the Company, the Initial Guarantor (as defined below) and Wilmington Trust FSB, as trustee (the “Trustee”). Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”) pursuant to a letter of representations, to be dated on or before the Closing Date (as defined in Section 2 hereof) (the “DTC Agreement”), between the Company and the Depositary.

The holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (the “Registration Rights Agreement”), among the Company, the Initial Guarantor and the Initial Purchasers, pursuant to which the Company and the Initial Guarantor may be required to file with the Commission (as defined below), under the circumstances set forth therein, (i) a registration statement under the Securities Act (as defined below) relating to another series of debt securities of the Company with terms substantially identical to the Notes (the “Exchange Notes”) and the Guarantors’ (as defined below) Exchange Guarantees (the “Exchange Guarantees”) to be offered in exchange for the Notes and the Guarantees (as defined below) (the “Exchange Offer”) and (ii) a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use their commercially reasonable efforts to cause such registration statements to be declared effective. All references herein to the Exchange Notes and the Exchange Offer are only applicable if the Company and the Initial Guarantor are in fact required to consummate the Exchange Offer pursuant to the terms of the Registration Rights Agreement.

The payment of principal of, premium, if any, and interest on the Notes and the Exchange Notes when and as the same becomes due and payable, will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally by (i) Banner Pipeline Company, L.L.C., the Company’s sole direct or indirect subsidiary (the “Initial Guarantor”) and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes a supplement to the Indenture guaranteeing the Notes in accordance with the terms of the Indenture, and their respective successors and assigns (together with the Initial Guarantor, the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees related thereto are herein collectively referred to as the “Securities”; and the Exchange Notes and the Guarantees related thereto are herein collectively referred to as the “Exchange Securities.”

Each of the Company and the Initial Guarantor understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)).

The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated September 13, 2010 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated September 13, 2010 in the form attached hereto as Annex II (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities. The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the “Pricing Disclosure Package.” Promptly after this Agreement is executed and delivered, the Company will prepare and deliver to each Initial Purchaser a final offering memorandum dated the date hereof (the “Final Offering Memorandum”).

All references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934 (as amended, the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) prior to the Time of Sale and incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Final Offering Memorandum (as the case may be), and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Final Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Final Offering Memorandum.

The Company will not amend or supplement the Final Offering Memorandum prior to the Closing Date unless the Representatives shall previously have been furnished a copy of the proposed amendment or supplement at least two business days prior to the proposed use or filing, and shall not have objected to such amendment or supplement. Before making, preparing, using, authorizing, approving or distributing any Company Additional Written Communication, the Company will furnish to the Representatives a copy of such written communication for review and will not make, prepare, use, authorize, approve or distribute any such written communication to which the Representatives reasonably object.

(b) Amendments and Supplements to the Final Offering Memorandum and Other Securities Act Matters. If, prior to the later of (x) the Closing Date and (y) the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Final Offering Memorandum, as then amended or supplemented, in order to make the statements therein, in the light of the circumstances when the Final Offering Memorandum is delivered to a Subsequent Purchaser, not misleading, or if in the judgment of the Representatives or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Final Offering Memorandum to comply with law, the Company agrees to promptly prepare (subject to Section 3 hereof), and furnish at its own expense to the Initial Purchasers, amendments or supplements to the Final Offering Memorandum so that the statements in the Final Offering Memorandum as so amended or supplemented will not, in the light of the circumstances at the Closing Date and at the time of sale of Securities, be misleading or so that the Final Offering Memorandum, as amended or supplemented, will comply with all applicable law.

(c) Copies of the Offering Memorandum. The Company agrees to furnish the Initial Purchasers, without charge, as many copies of the Pricing Disclosure Package and the Final Offering Memorandum and any amendments and supplements thereto as they shall reasonably request.

None of the Company or Initial Guarantor shall be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation. The Company will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, each of the Company and the Initial Guarantor shall use its commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible moment.

Additionally, at any time when the Company is not subject to Section 13 or 15 of the Exchange Act, for the benefit of holders and beneficial owners from time to time of the Securities, the Company shall furnish, at its expense, upon request, to holders and beneficial owners of Securities and prospective purchasers of Securities information (“Additional Issuer Information”) satisfying the requirements of Rule 144A(d).

(h) Agreement Not To Offer or Sell Additional Securities. During the period of 45 days following the date hereof, the Company will not, without the prior written consent of Banc of America Securities LLC (which consent may be withheld at the sole discretion of Banc of America Securities LLC), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1 under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act in respect of, any debt securities of the Company or securities exchangeable for or convertible into debt securities of the Company (other than as contemplated by this Agreement and to register the Exchange Securities). For the avoidance of doubt, this paragraph (h) shall not affect the Company’s ability to borrow amounts under its revolving credit facility or to increase the borrowing base thereunder.

14

(i) Future Reports to the Initial Purchasers.

(j) No Integration. The Company agrees that it will not and will cause its Affiliates not to make any offer or sale of securities of the Company of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for the purpose of (i) the sale of the Securities by the Company to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the Securities Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise.

(k) No Restricted Resales. During the period of one year after the Closing Date, 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 Notes which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

SECTION 8. Indemnification.

(a) Indemnification of the Initial Purchasers. Each of the Company and the Initial Guarantor, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its directors, officers, employees and affiliates and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company or as otherwise permitted by Section 8(d) hereof), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based: (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Information or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; or (iv) any act or failure to act or any alleged act or failure to act by any Initial Purchaser in connection with, or relating in any manner to, the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (i) above, provided that the Company shall not be liable under this clause (iv) to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Initial Purchaser through its gross negligence or willful misconduct; and to reimburse each Initial Purchaser and each such director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by Banc of America Securities LLC) as such expenses are reasonably incurred by such Initial Purchaser or such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Information or the Final Offering Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

19

(b) Indemnification of the Company and the Initial Guarantor. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, the Initial Guarantor, each of their respective directors and officers and each person, if any, who controls the Company or the Initial Guarantor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, the Initial Guarantor or any such director or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser or as otherwise permitted by Section 8(d) hereof), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Information or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of 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 to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Information or the Final Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Representatives on behalf of such Initial Purchaser expressly for use therein; and to reimburse the Company, the Initial Guarantor and each such director or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, the Initial Guarantor or such director or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Company and the Initial Guarantor hereby acknowledges that the only information that the Initial Purchasers through the Representatives have furnished to the Company expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Company Additional Written Information or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the second and third sentences of the sixth paragraph and the eleventh paragraph under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

20

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel)), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

21

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Initial Guarantor, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement 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 Initial Guarantor, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Initial Guarantor, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Company and the Initial Guarantor, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company and the Initial Guarantor, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Company, the Initial Guarantor and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 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 which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 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 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company or the Initial Guarantor, and each person, if any, who controls the Company or the Initial Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Initial Guarantor.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company if at any time: (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the NYSE; (ii) trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (iii) a general banking moratorium shall have been declared by any federal, New York or Oklahoma authorities; (iv) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to proceed with the offering sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; and (v) the representation in Section 1(d) is incorrect in any respect. Any termination pursuant to this Section 10 shall be without liability on the part of (a) the Company or the Initial Guarantor to any Initial Purchaser, except that the Company and the Initial Guarantor shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (b) any Initial Purchaser to the Company, or (c) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Initial Guarantor, their respective officers and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, the Company, the Initial Guarantor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 16. Governing Law Provisions.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

SECTION 17. Default of One or More of the Several Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the principal amount of Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

SECTION 18. No Advisory or Fiduciary Responsibility. Each of the Company and the Initial Guarantor acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Initial Guarantor, on the one hand, and the several Initial Purchasers, on the other hand, and the Company and the Initial Guarantor are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company, Initial Guarantor or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or the Initial Guarantor with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company or the Initial Guarantor on other matters) or any other obligation to the Company and the Initial Guarantor except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Initial Guarantor and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Initial Guarantor have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

25

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Initial Guarantor and the several Initial Purchasers, or any of them, with respect to the subject matter hereof. The Company and the Initial Guarantor hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Initial Guarantor may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

SECTION 19. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

26

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

The foregoing Purchase Agreement is hereby confirmed and accepted by the Initial Purchasers as of the date first above written.

Such Initial Purchaser agrees that, during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S.

Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a selling concession, fee or other remuneration during the 40-day restricted period referred to in Rule 903 of Regulation S, it will send to such distributor, dealer or person receiving a selling concession, fee or other remuneration a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of your distribution at any time or (ii) otherwise until 40 days after the later of the date the Securities were first offered to persons other than distributors in reliance upon Regulation S and the Closing Date, except in either case in accordance with Regulation S under the Securities Act (or in accordance with Rule 144A under the Securities Act or to accredited investors in transactions that are exempt from the registration requirements of the Securities Act), and in connection with any subsequent sale by you of the Securities covered hereby in reliance on Regulation S under the Securities Act during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice to substantially the foregoing effect. Terms used above have the meanings assigned to them in Regulation S under the Securities Act.”
