The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x).

          4. Offering by the Underwriters. The Company understands that the several Underwriters propose to offer the Securities for sale to the public as set forth in the Final Prospectus.

          5. Agreements. The Company agrees with the several Underwriters that:

          (a) The Company will use its best efforts to cause any amendment to the Registration Statement to become effective. Prior to the termination of the offering of the Securities, the Company will not file any amendment to the Registration Statement or supplement (including the Final Prospectus, any Preliminary Prospectus or the Time of Sale Information) to the Basic Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. Subject to the foregoing sentence, if the Registration Statement has become effective pursuant to Rule 430A or Rule 430B, or filing of the Final Prospectus is otherwise required under Rule 424(b), the Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. The Company will promptly advise the Representatives (1) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (2) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (3) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (4) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (5) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

          (b) If the Time of Sale Information is being used to solicit offers to buy the Securities at a time when the Final Prospectus is not yet available to prospective purchasers and any event occurs as a result of which the Time of Sale Information 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 any event occurs or condition exists as a result of which the Time of Sale Information conflicts with the information contained or incorporated by reference in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Information to comply with applicable law, the Company will forthwith prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Information so that the statements in the Time of Sale Information, as so amended or supplemented will not, in the light of the circumstances under which they were made when delivered to a prospective purchaser, be misleading or so that the Time of Sale Information, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Information, as amended or supplemented, will comply with applicable law.

          (c) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Final Prospectus as then 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 the Registration Statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, the Company promptly will (1) notify the Representatives of such event, (2) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance and (3) supply any supplemented Final Prospectus to the underwriters in such quantities as the representatives may reasonably request.

          (d) As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (e) The Company will furnish to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act, as many copies of the Time of Sale Information and the Final Prospectus and any supplement thereto as the Representatives may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering.

          (f) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the National Association of Securities Dealers, Inc., in connection with its review of the offering; 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 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.

          (g) The Company will furnish to the Underwriters a copy of each proposed Free Writing Prospectus to be prepared by or on behalf of, used by, or referred to by the Company and will not use or refer to any proposed Free Writing Prospectus to which the Underwriters reasonably object.

          (h) The Company will not take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Act a Free Writing Prospectus prepared by or on behalf of any Underwriter that the Underwriter otherwise would not have been required to file thereunder.

          (i) The Company will not, without the prior written consent of the Representatives, (i) offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company) or any person in privity with the Company or any affiliate of the Company, directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or (ii) establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Rule 16a of the Exchange Act in respect of, any debt securities issued or guaranteed by the Company with a maturity in excess of one year or publicly announce an intention to effect any such transaction, until the Closing Date.

          (j) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

          (k) In connection with the offering of the Securities: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person; (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company and are not obligated to disclose such interests.

          (l) If the third anniversary of the initial effective date of the Registration Statement occurs before all the Securities have been sold by the Underwriters, prior to such third anniversary the Company will file a new shelf registration statement and take any other action necessary to permit the public offering of the Securities to continue without interruption; references herein to the Registration Statement shall include the new registration statement declared effective by the Commission.

          (m) The Company will prepare a final term sheet relating to the offering of the Securities, substantially in the form of Exhibit A to Schedule III, containing only information that describes the final terms of the Securities or the offering in a form consented to by the Representatives, and will file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Act following the date the final terms have been established for the offering of the Securities.

          (n) 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(h)(1), and (b) contains only (i) information describing the preliminary terms of the Securities or their offering, (ii) information that is permitted by Rule 134 of the Act or (iii) information that describes the final terms of the Securities or their offering and that is included in the final term sheet of the Company contemplated in Section 5(m); provided that each Underwriter severally covenants with the Company not to take any action without the Company’s prior consent that would result in the Company being required to file with the Commission under Rule 433(d) under the Act a Free Writing Prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

          6. Conditions to the Obligations of the Underwriters.
