It is understood, however, that, except as provided in this Section 4(f) or Sections 7 and 9 hereof, the Underwriters will pay all of their own costs and expenses, including the fees and expenses of counsel to the Underwriters and any advertising expenses incurred in connection with the offering of the Notes. If the sale of the Notes provided for herein is not consummated by reason of acts of the Company or changes in circumstances of the Company pursuant to Section 9 of this Agreement which prevent this Agreement from becoming effective, or by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed or because any other condition of the Underwriters’ obligations hereunder is not fulfilled or if the Underwriters decline to purchase the Notes for any reason permitted under this Agreement, the Company will reimburse the Underwriters for all reasonable out-of-pocket disbursements (including fees and expenses of counsel to the Underwriters) incurred by the Underwriters in connection with any investigation or preparation made by them in respect of the marketing of the Notes or in contemplation of the performance by them of their obligations hereunder.

(g) Until completion of the distribution of the Notes, the Company will timely file all reports, documents and amendments to previously filed documents required to be filed by it pursuant to Section 12, 13(a), 13(c), 14 or 15(d) of the Exchange Act.

(h) The Company will apply the net proceeds from the sale of the Notes as set forth in the most recent Preliminary Prospectus and the Prospectus.

(i) Until 30 days following the Closing Date, the Company will not, without the prior written consent of the Representatives, directly or indirectly, issue, sell, offer to sell, grant any option for the sale of or otherwise dispose of, any debt securities that are substantially similar to the Notes (including, without limitation, with respect to the maturity, currency, interest rate and other material terms of the Notes).

(j) The Company will pay the required Commission filing fees relating to the Notes within the time period required by Rule 456(b)(1) of the Rules and Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Rules and Regulations.

(k) If required by Rule 430B(h) of the Rules and Regulations, the Company will prepare a prospectus in a form approved by the Representatives and file such prospectus pursuant to Rule 424(b) of the Rules and Regulations not later than may be required by such Rule; and the Company will make no further amendment or supplement to such prospectus that will be disapproved by the Representatives promptly after reasonable notice thereof.

(l) The Company will cooperate with the Underwriters and with counsel to the Underwriters in connection with the qualification of the Notes for offering and sale by the Underwriters and by dealers under the securities laws of such jurisdictions as the Underwriters may designate and will file such consents to service of process or other documents necessary or appropriate in order to effect such qualification and to permit the continuance of sales and dealings in such jurisdictions for as long as may be necessary to complete the distribution of the Notes; provided, however, that in no event will the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to service of process in suits, other than for actions or proceedings arising out of the offering or sale of the Notes, in any jurisdiction where it is not now so subject.

(m) The Company will not take, directly or indirectly, any action designed to cause or result in, or that might cause or result in, stabilization or manipulation of the price of the Notes to facilitate the sale or resale of the Notes.

(n) The Company will comply with all agreements set forth in the representation letters of the Company to DTC relating to the acceptance of the Notes for “book-entry” transfer through the facilities of DTC.

5. Free Writing Prospectuses.

(a) The Company represents and warrants to, and agrees with, each Underwriter that (i) the Company has not made, and will not, make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus without the prior consent of the Representatives (which consent being deemed to have been given with respect to (A) the Final Term Sheet prepared and filed pursuant to Section 4(a) hereof and (B) any other Issuer Free Writing Prospectus identified on Schedule II hereto); (ii) each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations on the date of first use, and the Company has complied with any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to Rule 433 of the Rules and Regulations; (iii) each Issuer Free Writing Prospectus will not, as of its issue date and

through the time the Notes are delivered pursuant to Section 3 hereof, include any information that conflicts with the information contained in the Registration Statement, the most recent Preliminary Prospectus and the Prospectus; and (iv) each Issuer Free Writing Prospectus, when considered together with the information contained in the most recent Preliminary Prospectus, did not, as of the Applicable Time, does not, as of the date hereof, and will not, as of the Closing Date, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(b) Each Underwriter represents and warrants to, and agrees with, the Company and each other Underwriter that it has not made, and will not make any offer relating to the Notes that would constitute a “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) required to be filed with the Commission, without the prior consent of the Company and the Representatives.

(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus or 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 the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission.

6. Conditions of Underwriters’ Obligations.

(f) Except as described in the most recent Preliminary Prospectus and the Prospectus, (i) neither the Company nor any of its Subsidiaries shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the most recent Preliminary Prospectus, 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 or any of its Subsidiaries or any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, stockholders’ equity, properties, business or prospects of the Company and its Subsidiaries taken as a whole, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the offering of the Notes or on the terms and in the manner contemplated in the Prospectus.

(g) Concurrently with the execution of this Agreement, the Representatives shall have received from Ernst & Young LLP, the Company’s independent registered public accounting firm, a “comfort” letter (the “initial comfort letter”) addressed to the Representatives on behalf of the Underwriters, dated the date hereof, and in form and substance satisfactory to the Representatives (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the most recent Preliminary Prospectus, as of a date not more than three days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings.

(j) Subsequent to the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded to the debt securities, preferred shares, financial strength or claims paying ability of the Company or any of its Subsidiaries by any “nationally recognized statistical rating organization” (as that term is defined in Rule 436(g)(2) of the Rules and Regulations), and (ii) no such organization shall have publicly announced that it has any such debt securities under surveillance or review with possible negative implications.

(k) 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 American Stock Exchange 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 banking moratorium 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; or (iv) 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 markets in the United States shall be such) as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offering of the Notes or on the terms and in the manner contemplated in the Prospectus. All opinions, certificates, letters and documents referred to in this Section 6 will be in compliance with the provisions of this Agreement only if they are satisfactory in form and substance to the Representatives and to counsel for the Underwriters. The Company will furnish to the Representatives conformed copies of such opinions, certificates, letters and other documents in such number as the Representatives will reasonably request.

7. Indemnification and Contribution.

(a) The Company will indemnify and hold harmless each Underwriter, its directors and officers and each person, if any, who controls the Company 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 (or any action in respect thereof), joint or several, to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage or liability (or action in respect thereof) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Disclosure Package, the Registration Statement or Prospectus as amended or supplemented, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, or (ii) the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Disclosure Package, or the Registration Statement or

Prospectus as amended or supplemented or any Issuer Free Writing Prospectus, any such issuer information, a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter promptly after receipt of invoices from such Underwriter for any legal or other expenses as reasonably incurred by such Underwriter in connection with investigating, preparing to defend or defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action, notwithstanding the possibility that payments for such expenses might later be held to be improper, in which case such payments will be promptly refunded; provided, however, that the Company will not be liable under this Section 7(a) in any such case to the extent, but only to the extent, that any such loss, claim, damage, liability or action arises out of or is based upon an 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, on behalf of the Underwriters, expressly therein (which information is specified in Section 12 hereof).

(b) Each Underwriter severally, but not jointly, will indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any loss, claim, damage or liability (or any action in respect thereof) to which the Company may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage or liability (or action in respect thereof) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Disclosure Package, the Registration Statement or Prospectus as amended or supplemented, or any Issuer Free Writing Prospectus, or (ii) the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Disclosure Package, the Registration Statement or Prospectus as amended or supplemented, or any Issuer Free Writing Prospectus, a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company promptly after receipt of invoices from the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating, preparing to defend or defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action notwithstanding the possibility that payments for such expenses might later be held to be improper, in which case such payments will be promptly refunded; provided, however, that such indemnification or reimbursement will be available in each such case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Representatives, on behalf of such Underwriter, expressly for use therein (which information is specified in Section 12 hereof).

(c) Promptly after receipt by any indemnified party under Section 7(a) or 7(b) above of notice of any claim or the commencement of any action, the indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to so notify the indemnifying party will not relieve it from any liability which it may have under this Section 7 except to the extent it has been prejudiced in any material respect by such failure or from any liability which it may have to an indemnified party

otherwise than under this Section 7. If any such claim or action will be brought against any indemnified party, and it notifies the indemnifying party thereof, the indemnifying party will 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 will not be liable to the indemnified party under Section 7(a) or 7(b) above for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation, except that the Underwriters will have the right to employ counsel to represent the Underwriters who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under Section 7(a) if (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Underwriters will have been advised by counsel that there may be one or more legal defenses available to the Underwriters which are different from or additional to those available to the Company and in the judgment of such counsel it is advisable for the Underwriters to employ separate counsel or (iii) the Company has failed to assume the defense of such action and employ counsel satisfactory to the Underwriters, in which event the fees and expenses of such separate counsel will be paid by the Company. No indemnifying party will, 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 (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b) above, then each indemnifying party will, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in Section 7(a) or 7(b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand 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 on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, or actions in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand will be deemed to be in the same proportion as the total net proceeds from the offering of the Notes (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. Relative fault will be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue

statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation (even if the Underwriters 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 in the first sentence of this Section 7(d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in the first sentence of this Section 7(d) will be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against any action or claim which is the subject of this Section 7(d). Notwithstanding the provisions of this Section 7(d), no Underwriter will be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to investors were offered to investors exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 7(d) to contribute are several in proportion to their respective underwriting obligations and not joint. Each party entitled to contribution agrees that upon the service of a summons or other initial legal process upon it in any action instituted against it in respect to which contribution may be sought, it will promptly give written notice of such service to the party or parties from whom contribution may be sought, but the omission so to notify such party or parties of any such service will not relieve the party from whom contribution may be sought for any obligation it may have hereunder or otherwise (except as specifically provided in Section 7(c) above).

(e) The obligations of the Company under this Section 7 will be in addition to any liability that the Company may otherwise have, and will extend, upon the same terms and conditions set forth in this Section 7, to the respective officers and directors of the Underwriters and each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 7 will be in addition to any liability that the respective Underwriters may otherwise have, and will extend, upon the same terms and conditions, to each director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Securities Act.

8. Substitution of Underwriters. If any Underwriter defaults in its obligation to purchase the principal amount of the Notes which it has agreed to purchase under this Agreement, the non-defaulting Underwriters will be obligated to purchase (in the respective proportions which the principal amount of the Notes set forth opposite the name of each non-defaulting Underwriter in Schedule I hereto bears to the total principal amount of the Notes less the principal amount of the Notes the defaulting Underwriter agreed to purchase set forth in Schedule I hereto) the principal amount of the Notes which the defaulting Underwriter agreed but failed to purchase; except that the non-defaulting Underwriters will not be obligated to purchase any of the Notes if the total principal amount of the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase exceed 9.09% of the total principal amount of the Notes, and any non-defaulting Underwriters will not be obligated to purchase

more than 110% of the principal amount of the Notes set forth opposite its name in Schedule I hereto. If the foregoing maximums are exceeded, the non-defaulting Underwriters, and any other underwriters satisfactory to the Representatives who so agree, will have the right, but will not be obligated, to purchase (in such proportions as may be agreed upon among them) all of the Notes. If the non-defaulting Underwriters or the other underwriters satisfactory to the Underwriters do not elect to purchase the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except for the indemnity and contribution agreements of the Company and the Underwriters contained in Section 7 of this Agreement. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter pursuant to this Section 8.

If the non-defaulting Underwriters or the other underwriters satisfactory to the Representatives are obligated or agree to purchase the Notes of a defaulting Underwriter, the Representatives may postpone the Closing Date for up to seven full Business Days in order that the Company may effect any changes that may be necessary in the Registration Statement or the Prospectus or in any other document or agreement, and the Company agrees to file promptly any amendments or any supplements to the Registration Statement or the Prospectus which, in the opinion of the Representatives, may thereby be made necessary.

Nothing contained herein will relieve a defaulting Underwriter of any liability it may have for damages caused by its default.

9. Termination. Until the Closing Date, this Agreement may be terminated by the Representatives on behalf of the Underwriters by giving notice as hereinafter provided to the Company if (i) the Company will have failed, refused or been unable, at or prior to the Closing Date, to perform any agreement on its part to be performed hereunder, (ii) any of the events described in Sections 6(j) and 6(k) of this Agreement, shall have occurred, or (iii) any other condition to the Underwriters’ obligations hereunder is not fulfilled. Any termination of this Agreement pursuant to this Section 9 will be without liability on the part of the Company or any Underwriter, except as otherwise provided in Sections 4(f) and 7 hereof.

Any notice referred to above may be given at the address specified in Section 11 of this Agreement in writing or by telegraph or telephone, and if by telegraph or telephone, will be immediately confirmed in writing.

10. Survival of Certain Provisions. The agreements contained in Section 7 of this Agreement and the representations, warranties and agreements of the Company contained in Sections 1 and 4 of this Agreement will survive the delivery of the Notes to the Underwriters hereunder and will remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party.

11. Notices. Except as otherwise provided in the Agreement, (a) whenever notice is required by the provisions of this Agreement to be given to the Company, such notice will be in writing by mail, telex or facsimile transmission addressed to the Company at 0000 Xxxxxxxxx Xxxxxxx, Xxxxx 000, Xxxxxxxxxx, Xxxxxxx, facsimile number (000) 000-0000, Attention: General Counsel, and (b) whenever notice is required by the provisions of this

Agreement to be given to the several Underwriters, such notice will be in writing by mail, telex or facsimile transmission addressed to the Representatives in care of Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, facsimile number (000) 000-0000, Attention: Syndicate Registration and Xxxxxxx, Xxxxx & Co., 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Registration Department (telephone number: (000) 000-0000) (in each case, with a copy to the General Counsel at the same address).

12. Information Furnished by Underwriters. The Underwriters severally confirm that the information appearing in the list of names of each of the Underwriters under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus and the statements in the second and third sentences of the third paragraph, the eighth paragraph and the first and second sentences of the ninth paragraph under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus, constitute the only written information furnished to the Company by the Representatives on behalf of the Underwriters, referred to in Sections 1(e), 1(f), 1(g), 7(a) and 7(b) of this Agreement.

13. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering of the Notes that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions.

(vii) None of the execution or delivery of the Agreement by the Company, the consummation of the transactions contemplated hereby, the execution and delivery of the Indenture and the Notes by the Company and compliance by the Company with all of the provisions of the Agreement, the Indenture and the Notes will result in a breach or violation of, or constitute a default under, or result in the creation or imposition of any claim, lien, encumbrance or security interest upon any property or asset of the Company under, (A) its Articles of Incorporation or Code of Regulations, (B) any agreement that is specified in Annex A or (C) any law or any rule, regulation, order or decree of any governmental agency or body or court known to us having jurisdiction over the Company or its properties or assets.

(viii) No consent, approval, order or authorization of any governmental agency or body or court is required in connection with the consummation of the transactions contemplated by the Agreement, except as such as have been obtained under the Securities Act and Trust Indenture Act and such consents, approvals, orders and authorizations required under the securities or “Blue Sky” laws of certain jurisdictions.

(ix) The Registration Statement and any amendment thereto have become effective under the Securities Act; and to our knowledge, the Commission has not issued any order preventing or suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or Issuer Free Writing Prospectus, and no proceeding for any such purpose or pursuant to Section 8A of the Securities Act against the Company or related to the offering has been instituted or threatened by the Commission, and the Commission has not notified the Company of any objection to the use of the form of the Registration Statement.

(x) The Registration Statement, as of the Effective Date, and the Prospectus, as of its date and as of the Closing Date, and any further amendments or supplements thereto made by the Company as of their respective effective or issue dates and as of the Closing Date, comply as to form in all material respects with the applicable requirements of the Securities Act and the Rules and Regulations and the Trust Indenture Act and the rules and regulations thereunder (other than the financial statements and notes thereto and the other financial data contained therein, as to which we express no opinion).

(xi) The documents incorporated by reference in the most recent Preliminary Prospectus and the Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed, in all material respects, to the requirements of the Securities Act and the Rules and Regulations or the Exchange Act or the rules and regulations thereunder, as applicable (except that we express no opinion as to the financial statements and notes thereto and the other financial data contained therein or omitted therefrom).

(xii) To our knowledge, there is no litigation or legal or governmental proceeding to which the Company or any of its Subsidiaries is a party or to which any property or assets of the Company or any of its Subsidiaries is subject or which is pending that is required to be disclosed in the most recent Preliminary Prospectus and the Prospectus and is not disclosed.

(xiii) The descriptions in the Registration Statement, the most recent Preliminary Prospectus and the Prospectus of laws, regulations and legal or governmental proceedings, to the extent they constitute matters of law and summaries of legal matters are accurate in all material respects.

(xiv) Neither the filing of the Registration Statement, the most recent Preliminary Prospectus or the Prospectus nor the offer or sale of the Notes as contemplated by this Agreement gives rise to any rights for or relating to the registration of any securities of the Company under any agreement that is specified in Annex A.

(xv) The statements set forth in the most recent Preliminary Prospectus and the Prospectus under the caption “Description of Notes”, insofar as they purport to describe certain terms and provisions of the Notes and the Indenture, are accurate and complete in all material respects.

(xvii) An Ohio court or U.S. federal court applying the choice of laws principles prevailing under the laws of the State of Ohio should give effect to the provisions in the Indenture, this Agreement and the Notes (hereinafter collectively referred to as the “Operative Agreements”) selecting the law of New York as the proper governing law thereof and will apply New York law, rather than the laws of the State of Ohio, to the construction and application of the terms of the Operative Agreements. In the event that such an Ohio or U.S. federal court were not to respect the choice of law in the Operative Agreements, such court will find that (a) the Notes, when authenticated by the Trustee in the manner provided for in the Indenture and delivered to you against payment of the consideration thereof in accordance with the terms of this Agreement, constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture, and (b) the Indenture constitutes a valid and legally binding instrument, enforceable against the Company in accordance with its terms.
