Each of the provisions of the Underwriting Agreement is incorporated herein by reference in its entirety, and shall be deemed to be a part of this Pricing Agreement to the same extent as if such provisions were set forth in full herein; and each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Pricing Agreement (it being understood that each representation and warranty in Section 2 of the Underwriting Agreement that refers to the Pricing Prospectus or the Prospectus shall be deemed to be a representation or warranty as of the date of this Pricing Agreement in relation to the Pricing Prospectus or the Prospectus relating to the Designated Securities). Each reference to the Representatives herein and in the provisions of the Underwriting Agreement so incorporated by reference shall be deemed to refer to the Representatives named in Schedule II hereto (the “Representatives”). Unless otherwise defined herein, terms defined in the Underwriting Agreement are used herein as therein defined.

The Prospectus (including, for the avoidance of doubt, a prospectus supplement relating to the Designated Securities), in all material respects in the form heretofore delivered to you, is now proposed to be filed with the Commission.

Subject to the terms and conditions set forth herein and in the Underwriting Agreement incorporated herein by reference, the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the time and place and at the purchase price to the Underwriters set forth in Schedule II hereto, the principal amount of Designated Securities set forth opposite the name of such Underwriter in Schedule I hereto.

2

If the foregoing is in accordance with your understanding, please sign and return to us five counterparts hereof, and upon acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof, including the provisions of the Underwriting Agreement incorporated herein by reference, shall constitute a binding agreement between each of the Underwriters and the Company.

Accepted as of the date hereof:
