(oo)    Solvency. Each of the Issuers and each of the Guarantors, on a consolidated basis, is, and immediately after the Closing Date will be, Solvent. As used herein, the term “Solvent” means, with respect to any person on a particular date, that on such date (i) the fair market value of the assets of such person is greater than the total amount of liabilities (including contingent liabilities) of such person, (ii) the present fair salable value of the assets of such person is greater than the amount that will be required to pay the probable liabilities of such person on its debts as they become absolute and matured, (iii) such person is able to realize upon its assets and pay its debts and other liabilities, including contingent obligations, as they mature and (iv) such person does not have unreasonably small capital.

(pp)    Regulations T, U, X. Neither the Issuers nor any Guarantor nor any of their respective subsidiaries nor any agent thereof acting on their behalf has taken, and none of them will take, any action that might cause this Agreement or the issuance or sale of the Securities to violate Regulation T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve System.

(qq)    Regulation S. The Issuers, the Guarantors and their respective affiliates and all persons acting on their behalf (other than the Initial Purchasers, as to whom the Issuers and the Guarantors make no representation) have complied with and will comply with the offering restrictions requirements of Regulation S in connection with the offering of the Securities outside the United States and, in connection therewith, the Offering Memorandum will contain the disclosure required by Rule 902. Each of the Issuers and each of the Guarantors is a “reporting issuer,” as defined in Rule 902 under the Securities Act.

Any certificate signed by an officer of the Issuers or any Guarantor and delivered to the Initial Purchasers or to counsel for the Initial Purchasers shall be deemed to be a representation and warranty by the Issuers or such Guarantor to each Initial Purchaser as to the matters set forth therein.

(a)The Securities. Each of the Issuers agrees to issue and sell to the Initial Purchasers, severally and not jointly, all of its Securities, and subject to the conditions set forth herein, the Initial Purchasers agree, severally and not jointly, to purchase from the Issuers the aggregate principal amount of Securities set forth opposite their names on Schedule A hereto, at a purchase price of 98.500% of the

principal amount thereof payable on the Closing Date, in each case, on the basis of the representations, warranties and agreements herein contained, and upon the terms herein set forth.

(b)The Closing Date. Delivery of the Securities to be purchased by the Initial Purchasers and payment therefor shall be made at the offices of Latham & Watkins LLP, 885 Third Avenue, Suite 1000, New York, New York 10022-4834 (or such other place as may be agreed to by the Issuers and the Representative) at 9:00 a.m. New York City time, on March 24, 2017, or such other time and date as may be agreed to by the Issuers and the Representative (the time and date of such closing are called the “Closing Date”). The Issuers hereby acknowledge that circumstances under which the Issuers and the Representative agree to postpone the Closing include, but are in no way limited to, any determination by the Issuers and the Initial Purchasers to recirculate to investors copies of an amended or supplemented Offering Memorandum or a delay as contemplated by the provisions of Section 18 hereof.

(c)Delivery of the Securities. The Issuers shall deliver, or cause to be delivered, to the nominee of the Depositary for the accounts of the several Initial Purchasers of the Notes to be purchased by them, in one or more global notes representing the Notes (collectively, the “Global Notes”) at the Closing Date against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefore to a bank account designated by the Company. The Global Notes shall be in such denominations and registered in the name of Cede & Co., as nominee of the Depositary, pursuant to the DTC Agreement, and shall be made available for inspection on the business day preceding the Closing Date at a location in New York City, as the Representative may designate. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Initial Purchasers.

(d)Initial Purchasers as Qualified Institutional Buyers. Each Initial Purchaser severally and not jointly represents and warrants to, and agrees with, each of the Issuers that:

(i)it will offer and sell the Securities only to persons who it reasonably believes are “qualified institutional buyers” within the meaning of Rule 144A (“Qualified Institutional Buyers”) in transactions meeting the requirements of Rule 144A or (b) upon the terms and conditions set forth in Annex I to this Agreement;

(ii)it is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act; and

(iii)it will not offer or sell the Securities by any form of general solicitation or general advertising, including but not limited to the methods described in Rule 502(c) under the Securities Act.

3.Additional Covenants. Each of the Issuers and each of the Guarantors further covenants and agrees with each Initial Purchaser as follows:

(a)Preparation of Final Offering Memorandum; Initial Purchasers’ Review of Proposed Amendments and Supplements and Issuer Additional Written Communications. As promptly as practicable following the Time of Sale and in any event not later than the second business day following the date hereof, the Issuers will prepare and deliver to the Initial Purchasers the Final Offering Memorandum, which shall consist of the Preliminary Offering Memorandum as modified only

by the information contained in the Pricing Term Sheet. The Issuers will not otherwise amend or supplement the Preliminary Offering Memorandum or the Pricing Term Sheet. The Issuers will not amend or supplement the Final Offering Memorandum prior to the Closing Date unless the Representative 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 reasonably objected to such amendment or supplement. Before making, preparing, using, authorizing, approving or distributing any Issuer Additional Written Communication, the Issuers will furnish to the Representative 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 Representative reasonably objects.

(b)Amendments and Supplements to the Final Offering Memorandum and Other Securities Act Matters. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading or (ii) it is necessary to amend or supplement any of the Pricing Disclosure Package to comply with law, the Issuers and the Guarantors will notify the Initial Purchasers thereof as soon as practicable and forthwith prepare and (subject to Section 3(a) hereof) furnish to the Initial Purchasers such amendments or supplements to any of the Pricing Disclosure Package as may be necessary so that the statements in any of the Pricing Disclosure Package as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or so that any of the Pricing Disclosure Package will comply with all applicable law. If, prior to the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers or prior to the expiration of nine months after the date of the Final Offering Memorandum, whichever is shorter, 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 reasonable judgment of the Representative or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Final Offering Memorandum to comply with law, the Issuers and the Guarantors agree to prepare (subject to Section 3(a) hereof), file with the Commission and furnish at its own expense to the Initial Purchasers as soon as practicable, 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.

The Company hereby expressly acknowledges that the indemnification and contribution provisions of Sections 8 and 9 hereof are specifically applicable and relate to each offering memorandum, amendment or supplement referred to in this Section 3.

(c)Copies of the Offering Memorandum. The Issuers agree 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.

(d)Blue Sky Compliance. Each of the Issuers and each of the Guarantors shall cooperate with the Representative and counsel for the Initial Purchasers to qualify or register (or to obtain exemptions from qualifying or registering) all or any part of the Securities for offer and sale under the securities or Blue Sky laws of the several states of the United States, the provinces of Canada, or any

other jurisdictions that the Representative may reasonably request, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. None of the Issuers or any of the Guarantors shall be required to qualify as a foreign organization 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 organization. The Company will advise the Representative as soon as practicable 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 to the knowledge of the Company, 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 Issuers and each of the Guarantors shall use its commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible moment.

(e)Use of Proceeds. The Issuers shall apply the net proceeds from the sale of the Securities sold by them in the manner described under the caption “Use of Proceeds” in the Pricing Disclosure Package.

(f)The Depositary. The Company will cooperate with the Initial Purchasers and use its commercially reasonable efforts to permit the Securities to be eligible for clearance and settlement through the facilities of the Depositary.

(g)Additional Issuer Information. Prior to the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers or prior to the expiration of nine months after the date of the Final Offering Memorandum, whichever is shorter, the Parent shall file, on a timely basis, with the Commission and the New York Stock Exchange (the “NYSE”) all reports and documents required to be filed under Section 13 or 15 of the Exchange Act. Additionally, at any time when the Parent 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 Parent shall furnish, at its expense, upon request, to holders and beneficial owners of Securities and prospective purchasers of Securities information satisfying the requirements of Rule 144A(d).

(h)Agreement Not To Offer or Sell Additional Securities. During the period of 90 days following the date hereof, the Issuers will not, without the prior written consent of the Representative (which consent may be withheld at the sole discretion of the Representative), 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 (other than a shelf-registration statement under which no specific offer or sale is being made, e.g. Form S-3 ASR) in respect of, any debt securities of the Issuers or the Parent or securities exchangeable for or convertible into debt securities of the Issuers or the Parent (other than as contemplated by this Agreement).

(i)Future Reports to the Initial Purchasers. At any time when the Parent is not subject to Section 13 or 15 of the Exchange Act and any Securities remain outstanding, the Parent will furnish to the Representative and, upon reasonable request, to each of the other Initial Purchasers: (i) as soon as practicable after the end of each fiscal year, copies of the Annual Report of the Parent containing the balance sheet of the Parent as of the close of such fiscal year and statements of income, stockholders’ equity and cash flows for the year then ended and the opinion thereon of the Parent’s independent public or certified public accountant.

(j)No Integration. Each of the Issuers agrees that it will not and will cause its Affiliates not to make any offer or sale of securities of the Issuers 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 Issuers to the Initial Purchasers, or (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers) 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 General Solicitation or Directed Selling Efforts. The Company agrees that it will not and will not permit any of its Affiliates or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no covenant is given) to (i) solicit offers for, or offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act or (ii) engage in any directed selling efforts with respect to the Securities within the meaning of Regulation S, and the Company will and will cause all such persons to comply with the offering restrictions requirement of Regulation S with respect to the Securities.

(l)No Restricted Resales. 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 that have been reacquired by any of them.

(m)Legended Securities. Each certificate for a Note will bear the legend contained in “Transfer Restrictions” in the Preliminary Offering Memorandum for the time period and upon the other terms stated in the Preliminary Offering Memorandum.

The Representative, on behalf of the several Initial Purchasers, may, in its sole discretion, waive in writing the performance by the Issuers or any Guarantor of any one or more of the foregoing covenants or extend the time for their performance.

Each of the Issuers and each of the Guarantors agrees to pay all costs, fees and expenses incurred in connection with the performance of its obligations hereunder and in connection with the Transactions contemplated hereby, including, without limitation, (i) all expenses incident to the issuance and delivery of the Securities (including all printing and engraving costs), (ii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Securities to the Initial Purchasers, (iii) all fees and expenses of the Issuers’ and the Guarantors’ counsel, independent public or certified public accountants and other advisors, (iv) all costs and expenses incurred in connection with the preparation, printing, filing, shipping and distribution of the Pricing Disclosure Package and the Final Offering Memorandum (including financial statements and exhibits), and all amendments and supplements thereto, and the Transaction Documents, (v) all filing fees, attorneys’ fees and expenses incurred by the Issuers, the Guarantors or the Initial Purchasers in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Securities for offer and sale under the securities laws of the several states of the United States, the provinces of Canada, or other jurisdictions that the Initial Purchasers may reasonably request (including, without limitation, the cost of preparing, printing and mailing preliminary and final blue sky or legal investment memoranda and any related supplements to the Pricing Disclosure Package or the Final Offering Memorandum), (vi) the fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities, (vii) any fees payable in connection with the rating of the Securities with the ratings agencies, (viii) all fees and expenses (including reasonable fees and expenses

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH 2(B) ABOVE, THE ISSUERS AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.”

Following the sale of the Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Issuers for any losses, damages or liabilities suffered or incurred by the Issuers, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer of any Security.

(a)Indemnification of the Initial Purchasers. Each of the Issuers and each of the Guarantors, jointly and severally, agrees 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 and Section 20 of the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under Section 15 of the Securities Act, Section 20 of 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 Issuers), 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 Term Sheet, any Issuer Additional Written Communication 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, and to reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by such Initial Purchaser or such affiliate, 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, with respect to an Initial Purchaser, to any loss, claim, damage, liability, expense or actions 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 Issuers by any Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the Pricing Term Sheet, any Issuer Additional Written Communication 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 Issuers may otherwise have.

(b)Indemnification of the Issuers and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Issuers, each Guarantor, each of their respective directors, officers and employees, and each person, if any, who controls the Issuers or any Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Issuers, any Guarantor or any such director, officer and employee, or controlling person may become subject, under Section 15 of the Securities Act, Section 20 of 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), 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 Term Sheet, any Issuer Additional Written Communication 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 Term Sheet, any Issuer Additional Written Communication or the Final

Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Issuers by any Initial Purchaser through the Representative expressly for use therein; and to reimburse the Issuers, any Guarantor and each such director, officer and employee, or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Issuers, any Guarantor or such director, officer or employee, or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Issuers and each of the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Issuers expressly for use in the Preliminary Offering Memorandum, the Pricing Term Sheet, any Issuer Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the ninth and tenth paragraphs and the third and fourth sentences of the seventh 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.

(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 Section 8(a) or Section 8(b), notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under Section 8(a) or Section 8(b) except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under Section 8(a) or Section 8(b). 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 Section 8(a) or Section 8(b) 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 immediately 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 (in each jurisdiction)), which shall be selected by the Representative (in the case of counsel representing the Initial Purchasers or their related persons), 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, which will not be unreasonably withheld, 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 or disputed in good faith the indemnified party’s entitlement to such reimbursement 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.

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 Issuers and the Guarantors, 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 Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Guarantors, 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 Issuers, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Issuers and the Guarantors, 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 relates to information supplied by the Issuers and the Guarantors, 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.

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 Guarantors 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 hereto. 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 Section 15 of the Securities Act and Section 20 of the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director officer and employee of the Issuers or any Guarantor, and each person, if any, who controls the Issuers or any Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Issuers and the Guarantors.

10.Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by notice given to the Issuers if at any time: (i) trading or quotation in any of the Issuers’ or Parent’s securities shall have been suspended or limited by the Commission or by the NYSE, or 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 such quotation system or stock exchange by the Commission or the Financial Industry Regulatory Authority, Inc.; (ii) a general banking moratorium shall have been declared by any of federal or New York or Delaware authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the U.S. or international financial markets, or any substantial change or development involving a prospective substantial change in U.S. or international political, financial or economic conditions, as 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 in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; or (iv) in the judgment of the Representative, there shall have occurred any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of the Parent and its subsidiaries taken as a whole which, is material and adverse and makes it impractical or inadvisable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package. Any termination pursuant to this Section 10 shall be without liability on the part of (i) the Issuers or any Guarantor to any Initial Purchaser, except that the Issuers and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Issuers, or (iii) 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.

11.Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Issuers, the Guarantors, 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 Issuers, any 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.

12.Notices. All communications hereunder shall be in writing and shall be mailed, hand delivered, couriered or facsimiled confirmed to the parties hereto, as follows:

Any party hereto may change the address or facsimile number for receipt of communications by giving written notice to the others.

13.Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the indemnified parties referred to in Sections 8 and 9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The

term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

14.Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by the Representative on behalf of the Initial Purchasers, and any such action taken by the Representative shall be binding upon the Initial Purchasers.

15.Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

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.

17.Consent to Jurisdiction; Waiver of Jury Trial. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding, as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Related Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18.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 the Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of the Securities set forth opposite their respective names on Schedule A hereto bears to the aggregate number of the 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 number of the Securities with respect to which such default occurs exceeds 10% of the aggregate number of the Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Issuers 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 Issuers 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 18. Any action taken under this Section 18 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

19.No Advisory or Fiduciary Responsibility. Each of the Issuers and each of the Guarantors 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 Issuers and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Issuers and the Guarantors 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 Issuers, the Guarantors 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 Issuers and the Guarantors 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 Issuers and the Guarantors on other matters) or any other obligation to the Issuers and the Guarantors 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 Issuers and the Guarantors, and 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 Issuers and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Issuers and the Guarantors may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Parent and its subsidiaries, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients.

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

Resale Pursuant to Regulation S. Each Initial Purchaser understands that:

Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or for the benefit or account of, a U.S. Person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act. 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.
