          1. Representations and Warranties . The Company represents and warrants to each Underwriter that:

“preliminary prospectus,” and such supplemented form of final prospectus relating to the Securities, in the form in which it shall be filed with the Commission pursuant to Rule 424(b) (including the Basic Prospectus as so supplemented) is hereinafter called the “Final Prospectus”. Any reference herein to the Registration Statement, the Basic Prospectus, any preliminary prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”) pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934 (the “Exchange Act”) on or before the date of this Agreement, or the issue date of the Basic Prospectus, any preliminary prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, any preliminary prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Basic Prospectus, any preliminary prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference.

     (b) At or prior to the time when sales of the Securities were first made (the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): a preliminary prospectus, dated May 28, 2008 (including the Basic Prospectus) hereinafter called the “Preliminary Prospectus,” and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Act) listed on Schedule III hereto.

     (c) As of the Time of Sale, when the Final Prospectus is first filed pursuant to Rule 424(b) under the Act, when, prior to the Closing Date (as defined in Section 3 hereof), any amendment to the Registration Statement becomes effective (including the filing of any document incorporated by reference in the Registration Statement), when any supplement to the Final Prospectus is filed with the Commission and at the Closing Date, (i) the Registration Statement, as amended as of any such time, and the Final Prospectus, as amended or supplemented as of any such time, and the Indenture complied and will comply in all material respects with the applicable requirements of the Act, the Trust Indenture Act of 1939 (the “Trust Indenture Act”) and the Exchange Act and the respective rules thereunder and (ii) the Registration Statement, as amended as of any such time, did not contain or will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading and the Final Prospectus, as amended or supplemented as of any such time, did not contain or will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that the Company makes no representations or warranties as to (1) that part of the Registration Statement which constitutes the Statement of Eligibility and Qualification of the Trustee (Form T-1) under the Trust Indenture Act or (2) the information contained in or omitted from the Registration Statement or the Final Prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative specifically for use in the

     (i) The Company is a corporation duly organized and validly existing in good standing under the laws of the State of Ohio with corporate power and authority to own and hold under lease its properties and conduct its business as described in the Time of Sale Information and the Final Prospectus and holds all material licenses and is duly qualified to conduct the business in which it is engaged in each jurisdiction or place where the conduct of its business requires such licenses or qualification and where the failure to be so licensed or qualified would have a material adverse effect on the business or financial condition of the Company and its subsidiaries taken as a whole (a “Material Adverse Effect”).

     (j) Each of the Company’s significant subsidiaries (as defined in Rule 1-02 of Regulation S-X) is duly organized and validly existing in good standing under the laws of the jurisdiction of its incorporation with corporate power and authority to own and hold under lease its properties and to conduct its business as described in the Time of Sale Information and the Final Prospectus;

The issue and sale of the Securities, the execution and delivery of this Agreement, the performance of the obligations of the Company set forth herein and the consummation of the transactions contemplated hereby and thereby will not conflict with or constitute a breach of, or default under, the charter or code of regulations of the Company or any of its subsidiaries, any agreement, indenture or other instrument to which the Company or any of its subsidiaries is a party or by which any of them or any of their property is bound, or any law, administrative regulation or court decree applicable to the Company or any of its subsidiaries, except, where any breach or default would not

     (b) (i) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (or such delivery is required but for Rule 172 under the Act), any event occurs as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances

under which they were made, not misleading, or if it shall be necessary to amend or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, the Company will promptly notify the Underwriters thereof and promptly prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance, and (ii) if at any time prior to the Closing Date, any event occurs as a result of which the Time of Sale Information 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 the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend or supplement the Time of Sale Information to comply with the Act or the Exchange Act or the respective rules thereunder, the Company will promptly notify the Underwriters thereof and promptly prepare and file with the Commission (to the extent required), subject to the first sentence of paragraph (a) of this Section 4, and furnish to the Underwriters and to such dealers as the Representative may designate, such amendments or supplements to the Time of Sale Information which will correct such statement or omission or which will effect such compliance.

     (d) The Company will furnish to the Representative and counsel for the Underwriters, without charge, copies of the Registration Statement (including exhibits thereto) and each amendment thereto which shall become effective on or prior to the Closing Date and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (or such delivery is required but for Rule 172 under the Act), as many copies of the Final Prospectus and any amendments thereof and supplements thereto and each Issuer Free Writing Prospectus as the Representative may reasonably request. The Company will pay the expenses of printing all documents relating to the offering unless otherwise agreed with the Representative.

     (e) The Company will arrange for the qualification of the Securities for sale under the laws of such jurisdictions as the Representative may reasonably designate and will maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to the service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

     (f) Until the Business Day following the Closing Date, the Company will not, without the prior consent of the Representative, offer, sell, contract to sell, or otherwise dispose of any debt securities of the Company which mature more than one year following the Closing Date and which are substantially similar to the Securities.

          (a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company); provided that the Company consents to the use by any Underwriter of a free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433 under the Act, and (b) contains only information describing the preliminary terms of the Securities or their offering, or information that describes the final terms of the Securities or their offering and that is included in the Pricing Term Sheet of the Company contemplated on Schedule IV.

     (e) The Company shall have furnished to the Representative a certificate of the Company signed by the Chairman of the Board, the President or any Vice President of the Company dated the Closing Date, to the effect that:

     (i) the representations and warranties of the Company in this Agreement are true and correct in all material respects on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

     (f) At the date of this Agreement and the Closing Date, Ernst & Young LLP shall have furnished to the Representative letters (which, with respect to any letter delivered on the Closing Date, may refer to letters previously delivered to the Representative, a copy of which shall be attached, in which case the letter provided at the Closing Date shall state that the previous letter can be relied on), dated respectively as of the date of this Agreement and as of the Closing Date, in form and substance satisfactory to the Representative, containing statements and information of the type ordinarily

     (h) Subsequent to the execution of this Agreement and prior to the Closing Date, there shall not have been any downgrading in the ratings of any of the Company’s debt securities, by any “nationally recognized statistical rating organization,” as such term is defined by the Commission for purposes of Rule 436(g)(2) under the Act or any public announcement by any such organization that it has under surveillance or review with negative implications, its rating of any of the Company’s debt securities (or proposed rating of the Securities).

          8. Reimbursement of Underwriters’ Expenses .

          (a) The Company agrees to indemnify and hold harmless each Underwriter and each person who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Basic Prospectus, any preliminary prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or the Time of Sale Information, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by them as such expenses are incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representative specifically for use therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

          (b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement and each person who controls the Company within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the

Representative specifically for use in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, 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 under subsections 9(a) and (b) hereof to the extent it is not prejudiced as a proximate result of such omission. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent that it may elect 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 satisfactory to such indemnified party; provided, however, that 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 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 assert 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 its election so to assume the defense of such action and approval by the indemnified party of counsel (which shall not be unreasonably withheld or delayed), the indemnifying party will not be liable to such indemnified party under this Section 9 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, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel (in addition to any local counsel), approved by the Representative in the case of paragraph (a) of this Section 9, representing the indemnified parties under such paragraph (a) who are parties to such action), (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii). The indemnifying party shall not be liable for any settlement of any such action effected without its written consent, but if settled with its written consent, or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify the indemnified parties against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional

release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (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 Final Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters 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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount of total underwriting discounts and commissions actually received by it under this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

          10. Default by an Underwriter . If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set

forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriter or Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date shall be postponed for such period, not exceeding seven days, as the Representative shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

          11. Termination . This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities, if prior to such time (i) trading in any securities of the Company shall have been suspended or materially limited by the Commission or the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange, American Stock Exchange or The Nasdaq National Market shall have been suspended or materially limited, (ii) a general moratorium on commercial banking activities in New York shall have been declared either by Federal or state authorities or a material disruption shall have occurred in commercial banking or securities settlement or clearance services in the United States or (iii) there shall have occurred any outbreak or escalation of hostilities or other international or domestic calamity, crisis or change in political, financial or economic conditions, the effect of which on the financial markets of the United States is such as to make it, in the judgment of the Representative, impracticable or inadvisable to offer, sell or deliver the Securities.

          12. No Advisory or Fiduciary Responsibility . The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person affiliated with the Company. Additionally, in connection with the offering of the Securities, neither the Representative nor any other Underwriter is advising the Company or any other person affiliated with the Company as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

          13. Representations and Indemnities to Survive . The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters 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 Underwriter or the Company or any of the officers, directors or controlling persons referred to in Section 9 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7, 8 and 9 hereof shall survive the termination or cancellation of this Agreement.

          14. Notices . All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representative, will be mailed, delivered or telexed and confirmed to it, at the addresses specified in Schedule I hereto; or, if sent to the Company, will be mailed, delivered or telexed and confirmed to it at 7000 Cardinal Place, Dublin, Ohio 43017, Attention: Chief Legal Officer.

          15. Successors . This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 9 hereof, and no other person will have any right or obligation hereunder. The term “successors and assigns” shall not include a purchaser, in its capacity as such, of the Securities from any of the Underwriters.

          16. APPLICABLE LAW . THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     If the foregoing is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicate hereof, whereupon this letter and your acceptance shall represent a binding agreement between the Company and the several Underwriters.

Exhibit A

[Form of Opinions to be Delivered by Shearman & Sterling LLP]

filed with the Commission, appears on its face to have been appropriately responsive in all material respects to the requirements of the Securities Exchange Act of 1934, as amended, and the applicable rules and regulations of the Commission thereunder, and (b) each of the Registration Statement and the Final Prospectus (other than the financial statements and other financial data contained or incorporated by reference therein or omitted therefrom and the Trustee’s Statement of Eligibility on Form T-1, as to which such counsel expresses no opinion) appears on its face to be appropriately responsive in all material respects to the requirements of the Act and the applicable rules and regulations of the Commission thereunder.

          No facts came to such counsel’s attention, based upon their participation in the preparation of the Registration Statement, the Time of Sale Information and the Final Prospectus and any amendments and supplements thereto and upon their review and discussion of the contents thereof, but without independent check or verification except as specified, nothing has come to their attention which would cause such counsel to believe that (i) the Registration Statement (other than the financial statements and other financial data contained or incorporated by reference therein or omitted therefrom and the Trustee’s Statement of Eligibility on Form T-1, as to which such counsel has not been requested to comment), at the time it became effective or as of the date of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Time of Sale Information (other than the financial statements and other financial data contained or incorporated by reference therein or omitted therefrom, as to which such counsel has not been requested to comment), at the Time of Sale, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) the Final Prospectus (other than the financial statements and other financial data contained or incorporated by reference therein or omitted therefrom, as to which such counsel has not been requested to comment), as of the date of the Final Prospectus Supplement or the Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

     1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Ohio.

     3. Except for permits and similar authorizations required under the securities or Blue Sky laws of certain jurisdictions (as to which I express no opinion), no consent, approval, authorization or other order of any regulatory body, administrative agency or other governmental body of or in the State of Ohio is legally required for the valid issuance and sale of the Securities to the Underwriters in the manner contemplated by the Underwriting Agreement.

     4. The Underwriting Agreement, the Indenture and the Securities have been duly authorized, executed and delivered by the Company.

     5. There are no legal or governmental proceedings known to me pending or threatened that are required to be described in the Registration Statement, the Time of Sale Information or the Final Prospectus that are not described as required, and there is no contract or document known to me of a character required to be described in the Registration Statement, the Time of Sale Information or the Final Prospectus or to be filed as an exhibit to the Registration Statement which is not described or filed as required.

     6. The execution, delivery and performance of the Underwriting Agreement, the Indenture and the Securities, compliance by the Company with all provisions thereof and the consummation by the Company of the transactions contemplated thereby do not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the certificate or articles of incorporation or bylaws or code of regulations of the Company or any of its Significant Subsidiaries or any agreement, indenture or other instrument known to me which the Company or any of its Significant Subsidiaries is a party or by which any of them is bound which conflict or default would have a Material Adverse Effect, and except where such breach or default would not have a Material Adverse Effect on the ability of the Company to perform its obligations under the Underwriting Agreement, the Indenture and the Securities, or (assuming compliance with all applicable state securities and Blue Sky laws and without opining as to the enforceability of rights of indemnity or contribution under applicable law) violate any law or administrative regulation of or in the State of Ohio or ruling or court decree known to me applicable to the Company or any of its Significant Subsidiaries or any of their respective property which violation would have a Material Adverse Effect, and except where such breach or default would not have a Material Adverse Effect on the ability of the Company to perform its obligations under the Underwriting Agreement, the Indenture and the Securities.

     Based upon my participation in the preparation of the Registration Statement, the Time of Sale Information and the Final Prospectus and any amendments and supplements thereto

Exhibit B

[Form of Opinions to be Delivered by John M. Adams, Associate General Counsel of the Company]

and upon my review and discussion of the contents thereof, nothing has come to my attention which would lead me to believe that the Registration Statement at the time it became effective, including the information, if any, deemed to be part of such Registration Statement at such time of effectiveness pursuant to Rule 430B under the Act, and at the date of the Underwriting Agreement, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, that the Time of Sale Information, at the Time of Sale (which we assume to be the date of the Underwriting Agreement) contained any untrue statement of any material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or that the Final Prospectus (as amended or supplemented, if applicable) as of its date or the Closing Date contains any untrue statement of a material fact or omits 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. In making the statements in the immediately preceding sentence, I am not expressing any opinion on the financial statements and financial exhibits and other financial data included (or incorporated by reference) therein or omitted therefrom and I am not responsible for the adequacy or accuracy of the derivation or compilation from the Company’s accounting records of the financial data included in the Registration Statement, the Time of Sale Information or the Final Prospectus and any amendments or supplements thereto.
