(e) To make generally available to its securityholders as soon as practicable, but in any event not later than eighteen months after the effective date of the Registration Statement (as defined in Rule 158(c)), an earning statement of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder (including at the option of the Company Rule 158); and

(f) To pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1) under the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act;

6. (a) The Company represents and agrees that, other than any final term sheet prepared and filed pursuant to Section 5(a) hereof, without the prior consent of the Representatives, the Company has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act, and any such free writing prospectus the use of which has been so consented to is listed on Schedule III hereto.

(b) The Company has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending;

(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 Pricing Prospectus or the Prospectus or would include an 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; provided, however, that this agreement shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter through the Representatives expressly for use therein.

7. (a) Each Underwriter represents and agrees that, other than one or more term sheets relating to the Securities containing customary information that do not require the filing of any material pursuant to Rule 433(d) except for the final term sheet prepared and filed pursuant to Section 4(a) hereof, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus (any such free writing prospectus referred to as an “Underwriter Free Writing Prospectus”);

(b) Each of the Underwriters has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Underwriter Free Writing Prospectus prepared or used by it, including timely filing with the Commission or retention where required and legending;

(c) In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of debentures to the public in that Relevant Member State prior to the publication of a prospectus in relation to the debentures which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of debentures to the public in that Relevant Member State at any time: (i) to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities; (ii) to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or (iii) in any other circumstances which do not require the publication by the issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this Section 7(c), the expression an “offer of debentures to the public” in relation to any debentures in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the debentures to be offered so as to enable an investor to decide to purchase or subscribe the debentures, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

(d) Each Underwriter has represented and agreed that: (i) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Xxx 0000 (the “FSMA”)) received by it in connection with the issue or sale of the debentures in circumstances in which Section 21(1) of the FSMA does not apply to the Company; and (ii) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the debentures in, from or otherwise involving the United Kingdom.

(e) Each Underwriter agrees that it will not offer or sell any Securities, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (which term as used in this Section 7(e) means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to a resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Securities and Exchange Law and any other applicable laws, regulations and ministerial guidelines of Japan.

8. The Company covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Securities under the Securities Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any Preliminary Prospectus and the Prospectus and amendments and supplements thereto, and any Issuer Free Writing Prospectus, and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or reproducing this Agreement, any Indenture, and the Blue Sky Memorandum and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 5(c) hereof, including the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of any Trustee and any agent of any Trustee and the fees and disbursements of counsel for any Trustee in connection with any Indenture and the Securities (to the extent the Trustee does not pay such fees); (vii) the filing fees incident to, and the fees and disbursements of counsel for the Underwriters in connection with, any required review by the National Association of Securities Dealers, Inc. of the terms of the sale of the Securities; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, Section 10 and Section 14 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make.

9. The obligations of the Underwriters of any Securities under this Agreement shall be subject, in the discretion of the Representatives, to the condition that all representations and warranties and other statements of the Company in or incorporated by reference in this Agreement are, at and as of the Time of Delivery, true and correct in all material respects, the

condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

(b) Xxxxxxxx & Xxxxxxxx LLP, counsel for the Underwriters, using reasonable efforts, shall have furnished to the Representatives such opinion or opinions, dated the Time of Delivery, with respect to the incorporation of the Company, the validity of the Securities, the Registration Statement, the Prospectus, and other related matters as the Representatives may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters;

(c) Mayer, Brown, Xxxx & Maw LLP, counsel for the Company, using reasonable efforts, shall have furnished to the Representatives their written opinion, which may be subject to reasonable and customary assumptions, qualifications and limitations and shall be dated such Time of Delivery, in form and substance reasonably satisfactory to the Representatives, to the effect that:

(iii) The Company has been duly qualified as a foreign corporation for the transaction of business and is in good standing in each jurisdiction in which the conduct of its business or the ownership or leasing of property requires such qualification, except where failure to qualify would not in the aggregate have a material adverse effect upon the Company and its subsidiaries taken as a whole;

(iv) The Significant Subsidiary has been duly incorporated and is validly existing as a corporation in good standing under the laws of its jurisdiction of incorporation; and all of the issued shares of capital stock of such subsidiary have been duly and

(v) To such counsel’s knowledge and other than as set forth in the Pricing Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which the Company has reasonable cause to believe will individually or in the aggregate have a material adverse effect on the financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole; and, to such counsel’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others;

(vi) This Agreement has been duly authorized, executed and delivered by the Company;

(vii) The Securities have been duly authorized, executed, authenticated, issued and delivered and constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture, subject, as to enforcement, to bankruptcy, insolvency, reorganization and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; and the Securities and the Indenture conform to the descriptions thereof in the Prospectus;

(ix) Assuming due authorization and execution by the Trustee, the issue and sale of the Securities and the compliance by the Company with all of the provisions of this Agreement and the consummation of the transactions herein and therein contemplated will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, the effects of which would, in the aggregate, be materially adverse to the Company and its subsidiaries taken as a whole, nor will such action result in any violation of the provisions of the Certificate of Incorporation or By-laws of the Company or any statute, order, rule or regulation known to such counsel of any court or governmental agency or body having jurisdiction over the Company or any of its subsidiaries or any of their properties;

(x) No consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issue

and sale of the Securities or the consummation by the Company of the transactions contemplated by this Agreement or the Indenture with respect to the Securities, except as have been obtained under the Securities Act and the Trust Indenture Act, and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Securities by the Underwriters;

(xi) The documents incorporated by reference in the Prospectus as amended or supplemented (other than the financial statements and other financial data therein, as to which such counsel need express no opinion or belief), when they became effective or were filed with the Commission, as the case may be, appear to have complied as to form in all material respects with the requirements of the Securities Act, or the Exchange Act, as applicable, and the rules and regulation of the Commission thereunder; and such counsel shall also state that no facts have come to their attention that lead them to believe that any of such documents (other than the financial statements and other financial data therein, as to which such counsel need express no opinion or belief) 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, in the light of the circumstances under which they were made when such documents were so filed, not misleading; and

(xii) The Registration Statement and the Prospectus and any amendments and supplements thereto made by the Company prior to the Time of Delivery (other than the financial statements and other financial data therein, as to which such counsel need express no opinion or belief) appear to comply as to form in all material respects with the requirements of the Securities Act, and the rules and regulations thereunder; although they do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Pricing Prospectus or the Prospectus, no facts have come to their attention that have caused them to believe (i) that any part of the Registration Statement, or any further amendment thereto made by the Company prior to the Time of Delivery (other than the financial statements and other financial data therein, as to which such counsel need express no opinion or belief), when such part or amendment became effective, 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) that the Disclosure Package, as of the Time of Sale, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances in which they were made, not misleading (other than the financial statements and other financial data therein, as to which such counsel need express no opinion or belief); or (iii) that, as of its date and as of the Time of Delivery, the Prospectus or any further amendment or supplement thereto made by the Company prior to the Time of Delivery (other than the financial statements and other financial data therein, as to which such counsel need express no opinion or belief) contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading; and they do not know of any amendment to the Registration Statement required to be filed or of any contracts or other documents of a character required to be filed as an exhibit to the Registration Statement or required to be incorporated by reference into the Prospectus or required to be described in the Registration Statement, the Basic

Prospectus or the Prospectus which are not filed or incorporated by reference or described as required;

In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the federal laws of the United States and the General Corporation Law of the State of Delaware and shall be entitled to rely in respect of the opinion in this clause upon opinions of local counsel believed to be reputable or counsel employed by the Company, and in respect of matters of fact, upon certificates of officers of the Company or its transfer agent;

(d) On the date of this Agreement at the Time of Sale, and at the Time of Delivery, the independent registered public accounting firm of the Company who have certified the financial statements of the Company and its subsidiaries included or incorporated by reference in the Registration Statement shall have furnished to the Representatives a letter, dated the date of this Agreement and a letter dated such Time of Delivery, respectively, to the effect set forth in Annex I hereto, and with respect to such letter dated such Time of Delivery, as to such other matters as the Representatives may reasonably request and in form and substance satisfactory to the Representatives;

(e) (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 Pricing 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, otherwise than as set forth or contemplated in the Pricing Prospectus, and (ii) since the respective dates as of which information is given in the Pricing Prospectus, 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 the business, financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the reasonable judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus;

(f) On or after the Time of Sale, (i) no downgrading shall have occurred in the rating accorded the Company’s debt securities by Xxxxx’x Investors Service, or the Standard & Poor’s Division of the McGraw Hill Companies Inc. and (ii) neither organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities; and

(g) The Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery of the Securities a certificate or certificates of officers of the Company satisfactory to the Representatives as to the accuracy in all material respects of the representations and warranties of the Company herein at and as of such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such Time of Delivery, and as to the matters set forth in subsections (a) and (e) of this Section.

10. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, 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 will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall 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 an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement relating to such Securities or any Issuer Free Writing Prospectus, and provided, further, that the Company shall not be liable to any Underwriter under the indemnity agreement in this subsection (a) to the extent that (i) any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, (ii) the Company has informed the Underwriters of such untrue statement or alleged untrue statement or omission or alleged omission in writing at least 24 hours prior to the Time of Sale, (iii) the Company has filed on Form 8-K an amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus with the Commission correcting such untrue statement or alleged untrue statement or omission or alleged omission prior to the Time of Sale and (iv) the Company has provided to the Underwriters an amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus correcting such untrue statement or alleged untrue statement or omission or alleged omission at least 24 hours prior to the Time of Sale and requested in writing that the Underwriters deliver such amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus to the persons to whom the Underwriters are selling the Securities and (v) such loss, claim, damage or liability results from the fact that such Underwriter has sold Securities to a person to whom such Underwriter has failed to deliver such amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus.

(b) Each Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto,

any Issuer Free Writing Prospectus, 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, 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 any Preliminary Prospectus, the Pricing Prospectus, the Registration Statement, the Prospectus as amended or supplemented, or any such amendment or supplement thereto, any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, 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 commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party, and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the foregoing, in no event shall more than one such separate counsel in each jurisdiction where an action is commenced be retained for all indemnified parties together and neither the indemnified party nor the indemnifying party, in the instance where the indemnifying party has assumed the defense of the indemnified party, shall settle any action, proceeding or investigation with respect to the indemnified party without the written consent of the other, which consent shall not be unreasonably withheld.

(d) If the indemnification provided for in this Section 10 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 of the Securities 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 or if the indemnified party failed to give the notice required under subsection (c) above, 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 of the Securities

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 such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company to the total underwriting discounts and commissions received by such Underwriters. 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 such Underwriters on the other and the parties’ relative intent, prejudice resulting from any failure to give notice of any action under sub-section (c), 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 by which the total price at which the applicable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which 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) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters of Securities in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to such Securities and not joint.

(e) The obligations of the Company under this Section 10 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 10 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

11. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to the representatives to purchase such Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the

Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Securities, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 8 hereof and the indemnity and contribution agreements in Section 10 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

12. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

13. This Agreement shall be subject to termination by the Representatives by notice to the Company if, on or after the Time of Sale, there shall have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock

Exchange; (ii) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities; or (iii) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; if the effect of any such event specified in this clause (iii) in the reasonable judgment of the Representatives, makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated by the Prospectus.

14. If this Agreement shall be terminated pursuant to Section 11 or Section 13 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Securities covered by this Agreement except as provided in Section 8 and Section 10 hereof; but, if for any other reason Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all reasonable out-of-pocket expenses approved in writing by the Representatives, including reasonable fees and disbursements of counsel, incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Securities, but the Company shall then be under no further liability to any Underwriter with respect to such Securities except as provided in Section 8 and Section 10 hereof.

15. In all dealings hereunder, the Representatives of the Underwriters shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in this Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the address of the Representatives as set forth in this Agreement; and if to the Company, shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement: Attention: Corporate Secretary; provided, however, that any notice to an Underwriter pursuant to Section 10(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire or telex constituting such Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

16. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 10 and Section 12 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

17. Time shall be of the essence of this Agreement. As used herein, “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

18. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto, or the financial, tax or other related consequences of the transaction for the Company.

19. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

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

21. This Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.
