2. Representations and Warranties of the Company and the Sellling Stockholder.

a. The Company represents and warrants to, and agrees with, the several Underwriters that:

(i) A registration statement (No. 333- 86076) relating to the Offered Securities, including a form of prospectus, has been filed with the Securities and Exchange Commission ("Commission") and either (i) has been declared effective under the Securities Act of 1933 ("Act") and is not proposed to be amended or (ii) is proposed to be amended by amendment or post-effective amendment. If such registration statement ("initial registration statement") has been declared effective, either (i) an additional registration statement ("additional registration statement") relating to the Offered Securities may have been filed with the Commission pursuant to Rule 462(b) ("Rule 462(b)") under the Act and, if so filed, has become effective upon filing pursuant to such Rule and the Offered Securities all have been

duly registered under the Act pursuant to the initial registration statement and, if applicable, the additional registration statement or (ii) such an additional registration statement is proposed to be filed with the Commission pursuant to Rule 462(b) and will become effective upon filing pursuant to such Rule and upon such filing the Offered Securities will all have been duly registered under the Act pursuant to the initial registration statement and such additional registration statement. If the Company does not propose to amend the initial registration statement or if an additional registration statement has been filed and the Company does not propose to amend it, and if any post-effective amendment to either such registration statement has been filed with the Commission prior to the execution and delivery of this Agreement, the most recent amendment (if any) to each such registration statement has been declared effective by the Commission or has become effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the Act or, in the case of the additional registration statement, Rule 462(b). For purposes of this Agreement, "Effective Time" with respect to the initial registration statement or, if filed prior to the execution and delivery of this Agreement, the additional registration statement means (i) if the Company has advised the Representatives that it does not propose to amend such registration statement, the date and time as of which such registration statement, or the most recent post-effective amendment thereto (if any) filed prior to the execution and delivery of this Agreement, was declared effective by the Commission or has become effective upon filing pursuant to Rule 462(c), or (ii) if the Company has advised the Representatives that it proposes to file an amendment or post-effective amendment to such registration statement, the date and time as of which such registration statement, as amended by such amendment or post-effective amendment, as the case may be, is declared effective by the Commission. If an additional registration statement has not been filed prior to the execution and delivery of this Agreement but the Company has advised the Representatives that it proposes to file one, "Effective Time" with respect to such additional registration statement means the date and time as of which such registration statement is filed and becomes effective pursuant to Rule 462(b). "Effective Date" with respect to the initial registration statement or the additional registration statement (if any) means the date of the Effective Time thereof. The initial registration statement, as amended at its Effective Time, including all information contained in the additional registration statement (if any) and deemed to be a part of the initial registration statement as of the Effective Time of the additional registration statement pursuant to the General Instructions of the Form on which it is filed and including all information (if any) deemed to be a part of the initial registration statement as of its Effective Time pursuant to Rule 430A(b) ("Rule 430A(b)") under the Act, is hereinafter referred to as the "Initial Registration Statement". The additional registration statement, as amended at its Effective Time, including the contents of the initial registration statement incorporated by reference therein and including all information (if any) deemed to be a part of the additional registration statement as of its Effective Time pursuant to Rule 430A(b), is hereinafter referred to as the "Additional Registration Statement". The Initial Registration Statement and the Additional Registration Statement are herein referred to collectively as the "Registration Statements" and individually as a "Registration Statement". The form of prospectus relating to the Offered Securities, as first filed with the Commission pursuant to and in accordance with Rule 424(b) ("Rule 424(b)") under the Act or (if no such filing is required) as included in a Registration Statement, is hereinafter referred to as the "Prospectus". No document has been or will be prepared or distributed in reliance on Rule 434 under the Act.

(ii) If the Effective Time of the Initial Registration Statement is prior to the execution and delivery of this Agreement: (i) on the Effective Date of the Initial Registration Statement, the Initial Registration Statement conformed in all material respects to the requirements of the Act and the rules and regulations of the Commission ("Rules and Regulations") and did

The certificates for the Firm Securities so to be delivered will be in definitive form, in such denominations and registered in such names as UBS requests and will be made available for checking and packaging at the above office of at least 24 hours prior to the First Closing Date.

Certificates in negotiable form for the Offered Securities to be sold by the Selling Stockholder, if any hereunder have been placed in custody, for delivery under this Agreement, under a Custody Agreement made with ▇▇▇▇▇▇▇ ▇. ▇▇▇▇ and ▇▇▇▇▇ ▇▇▇▇▇, as custodians ("Custodians"). The Selling Stockholder agrees that the shares represented by the certificates held in custody for the Selling Stockholder under such Custody Agreements are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Stockholder for such custody are to that extent irrevocable, and that the obligations of the Selling Stockholder hereunder shall not be terminated by operation of law, whether by the death of any individual Selling Stockholder or the occurrence of any other event, or in the case of a trust, by the death of any trustee or trustees or the termination of such trust.

any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by UBS to the Company and a Custodian.

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 (e) to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) The obligations of the Company and the Selling Stockholder under this Section shall be in addition to any liability which the Company and the Selling Stockholder 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 Act; and the obligations of the Underwriters under this Section 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 director of the Company, to each officer of the Company who has signed a Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.
