The 1,000,000 shares of Preferred Stock to be purchased by the Underwriters and all or any part of the 150,000 shares of Preferred Stock subject to the option described in Section l(b) hereof are hereinafter called, collectively, the “Shares.”

The Company understands that the Underwriters propose to offer the Shares for sale to the public as set forth in the Prospectus (as defined below).

The Company has filed with the Securities and Exchange Commission (the “Commission”) a shelf registration statement on Form S-3 (No. 333-115392) relating to the registration of the Shares under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder (the “Securities Act Regulations”). Such registration statement was first declared effective on May 25, 2004. The Company has prepared and filed such amendments to such registration statement and such preliminary and final prospectuses and prospectus supplements as may have been required to the date hereof, and will file such additional amendments thereto and such amended prospectuses and prospectus supplements as may hereafter be required. Such registration statement, including all information deemed to be a part of the registration statement (whether by incorporation by reference, pursuant to Rule 430A(b) of the Securities Act Regulations or otherwise), is hereinafter called the “Registration Statement,” except that, if the Company files a post-effective amendment to such registration statement which becomes effective prior to the Closing Time (as defined below), “Registration Statement” shall refer to such registration statement as so amended. Any registration statement filed pursuant to Rule 462(b) of the Securities Act Regulations is hereinafter called the “Rule

462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the 462(b) Registration Statement. The Company has furnished to you, for use by the Underwriters and by dealers, copies of a preliminary prospectus, subject to completion, dated October 25, 2004, relating to the Shares (including the documents incorporated therein by reference, the “Preliminary Prospectus”).

The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus or Prospectus.

(d) No amendment or supplement to the Registration Statement or Prospectus shall have been filed to which the Underwriters shall have objected in writing.

(e) Prior to the Closing Time and each Date of Delivery (i) no stop order suspending the effectiveness of the Registration Statement or any order preventing or suspending the use of any Preliminary Prospectus or Prospectus shall have been issued, and no proceedings for such purpose shall have been initiated or threatened, by the Commission, and no suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes, shall have occurred and, in any such instance, not been waived by the Commission; and (ii) the Registration Statement and the Prospectus shall not contain an untrue statement of material fact or omit 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, not misleading.

(g) The Shares shall have been approved for inclusion in the New York Stock Exchange.

(h) If the issuance and sale of the Initial Shares and/or Option Shares to the Underwriters will result in the Underwriters individually or in the aggregate exceeding the Aggregate Stock Ownership Limit (as defined in the Amended Articles of Incorporation of the Company as of the date hereof) with respect to the Company’s capital stock, then, on or prior to the Closing Time, the Underwriters shall have received from the Company’s Board of Directors a waiver or exemption from the Aggregate Stock Ownership Limit with respect to the issuance

materially adversely affect the business or operations of the Company which, in the case of a prospective effect, cannot reasonably be expected to be remedied by the Company prior to the occurrence of such effect, or (vi) any action has been taken by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in the reasonable opinion of the Representative has a material adverse effect on the securities markets in the United States.

If the Representative elects to terminate this Agreement as provided in this Section 7, the Company and the Underwriters shall be notified promptly by telephone, promptly confirmed by facsimile.

If the sale to the Underwriters of the Shares, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because the Company shall be unable to comply in all material respects with any of the terms of this Agreement, the Company shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 5 and 9 hereof) and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

8. Increase in Underwriters’ Commitments. If any Underwriter shall default at the Closing Time or on a Date of Delivery in its obligation to take up and pay for the Shares to be purchased by it under this Agreement on such date the Representative shall have the right, within 36 hours after such default, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters satisfactory to the Company, to purchase all, but not less than all, of the Shares which such Underwriter shall have agreed but failed to take up and pay for (the “Defaulted Shares”). Absent the completion of such arrangements within such 36 hour period, (i) if the total number of Defaulted Shares does not exceed 10% of the total number of Shares to be purchased on such date, each non-defaulting Underwriter shall take up and pay for (in addition to the number of Shares which it is otherwise obligated to purchase on such date pursuant to this Agreement) the portion of the total number of Shares agreed to be purchased by the defaulting Underwriter on such date in the proportion that its underwriting obligations hereunder bears to the underwriting obligations of all non-defaulting Underwriters; and (ii) if the total number of Defaulted Shares exceeds 10% of such total, the Representative may terminate this Agreement by notice to the Company, without liability to any non-defaulting Underwriter except as set forth in Section 9 (provided that if such default occurs with respect to the Initial Shares after the Closing Time, this Agreement will not terminate as to the Initial Shares or any Option Shares purchased prior to such termination).

Without relieving any defaulting Underwriter from its obligations hereunder, the Company agrees with the non-defaulting Underwriters that it will not sell any Shares hereunder on such date unless all of the Shares to be purchased on such date are purchased on such date by the Underwriters (or by substituted Underwriters selected by the Representative with the approval of the Company or selected by the Company with the approval of the Representative).

If a new Underwriter or Underwriters are substituted for a defaulting Underwriter in accordance with the foregoing provision, the Company or the non-defaulting Underwriters shall have the right to postpone the Closing Time or the relevant Date of Delivery for a period not

exceeding five business days in order that any necessary changes in the Registration Statement and Prospectus and other documents may be effected.

The term Underwriter as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with the like effect as, if such substituted Underwriter had originally been named in this Agreement.

(a) The Company agrees to indemnify, defend and hold harmless each Underwriter and any person who controls any Underwriter within the meaning of the Securities Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or controlling person may incur under the Securities Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (i) any breach of any representation, warranty or covenant of the Company contained herein, (ii) any failure on the part of the Company to comply with any applicable law, rule or regulation relating to the offering of securities being made pursuant to the Prospectus, (iii) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or in a Prospectus (the term Prospectus for the purpose of this Section 9 being deemed to include any Preliminary Prospectus, the Prospectus and the Prospectus as amended or supplemented by the Company), or (iv) any omission or alleged omission to state a material fact required to be stated in either such Registration Statement or Prospectus or necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, except insofar as any such loss, expense, liability, damage or claim arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in and in conformity with information furnished in writing by the Underwriters through the Representative to the Company expressly for use in such Registration Statement or such Prospectus, provided, however, that the indemnity agreement contained in this subsection (a) with respect to the Preliminary Prospectus or the Prospectus shall not inure to the benefit of an Underwriter (or to the benefit of any person controlling such Underwriter) with respect to any person asserting any such loss, expense, liability, damage or claim which is the subject thereof if the Prospectus or any supplement thereto prepared with the consent of the Representative and furnished to the Underwriters prior to the Closing Time corrected any such alleged untrue statement or omission and if such Underwriter failed to send or give a copy of the Prospectus or supplement thereto to such person at or prior to the written confirmation of the sale of Shares to such person, unless such failure resulted from noncompliance by the Company with Section 4(b) above).

(b) If any action is brought against an Underwriter or controlling person in respect of which indemnity may be sought against the Company pursuant to subsection (a) above, such Underwriter shall promptly notify the Company, as applicable, in writing of the institution of such action, and the Company, as applicable, shall assume the defense of such action, including the employment of counsel of its choosing and payment of expenses, provided, however, that any failure or delay to so notify the Company, as applicable, will not relieve the Company, as applicable, of any obligation hereunder, except to the extent that its ability to

defend is actually impaired or otherwise prejudiced by such failure or delay, and after notice from the Company to such indemnified party of its election so to assume the defense thereof, the Company will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Such Underwriter or controlling person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless the employment of such counsel shall have been authorized in writing by the Company, as applicable, in connection with the defense of such action, or the Company, as applicable, shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of such action by such indemnified party or such indemnified party or parties shall have reasonably concluded (based on the advice of counsel) that there exists an actual and material conflict of interest between the interests of the Company and such indemnified party in connection with such action (in which case the Company shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Company, as applicable, and paid as incurred (it being understood, however, that the Company shall not be liable for the expenses of more than one separate firm of attorneys for the Underwriters or controlling persons in any one action or series of related actions in the same jurisdiction (other than local counsel in any such jurisdiction) representing the indemnified parties who are parties to such action). Anything in this paragraph to the contrary notwithstanding, the Company shall not be liable for any settlement of any such claim or action effected without its prior written consent.

(c) Each Underwriter agrees, severally and not jointly, to indemnify, defend and hold harmless the Company, the Company’s directors and officers, and any person who controls the Company within the meaning of the Securities Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, the Company, or any such person may incur under the Securities Act, the Exchange Act or otherwise, but only insofar as such loss, expense, liability, damage or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by such Underwriter through the Representative to the Company expressly for use in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or in a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated either in such Registration Statement or Prospectus or necessary to make such information, in the light of the circumstances under which made, not misleading. The statements set forth (i) in the last paragraph on the cover page and (ii) under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus constitute the only information furnished by or on behalf of any Underwriter through the Representative to the Company for purposes of Section 3(j) and this Section 9.

(d) If any action is brought against the Company or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Company or such person shall promptly notify the Representative in writing of the institution of such action and the Representative, on behalf of the Underwriters, shall assume the defense of such action, including the employment of counsel of its choosing (who shall not, except with the reasonable consent of the Company, be counsel to the Representative or the Underwriters) and

payment of expenses; provided, however, that any failure or delay to so notify the Representative, as applicable, will not relieve the Representative or the Underwriters, as applicable, of any obligation hereunder, except to the extent that their ability to defend is actually impaired or otherwise prejudiced by such failure or delay, and after notice from such Underwriter to such indemnified party of its election so to assume the defense thereof, such Underwriter will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. The Company or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company or such person unless the employment of such counsel shall have been authorized in writing by the Representative in connection with the defense of such action or the Representative shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of such action by such indemnified party or such indemnified party or parties shall have reasonably concluded (based on the advice of counsel) that there exists an actual and material conflict of interest between the interests of the Company and such indemnified party in connection with such action (in which case the Representative shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such Underwriter and paid as incurred (it being understood, however, that the Underwriters shall not be liable for the expenses of more than one separate firm of attorneys in any one action or series of related actions in the same jurisdiction (other than local counsel in any such jurisdiction) representing the indemnified parties who are parties to such action). Anything in this paragraph to the contrary notwithstanding, no Underwriter shall be liable for any settlement of any such claim or action effected without the prior written consent of the Representative.

(e) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a), (b), (c) and (d) of this Section 9 in respect of any losses, expenses, liabilities, damages or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, expenses, liabilities, damages or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Underwriters from the offering of the Shares or (ii) if (but only if) the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and of the Underwriters in connection with the statements or omissions which resulted in such losses, expenses, liabilities, damages or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as, the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company, as applicable, bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault of the Company and of the Underwriters shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any

legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any claim or action which is the subject of this subsection (e).

(f) Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of underwriting discounts and commissions applicable to the Shares purchased by such Underwriter. 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 Underwriters’ obligations to contribute pursuant to this Section 9 are several in proportion to their respective underwriting commitments and not joint.

10. Survival. The indemnity and contribution agreements contained in Section 9 and the covenants, warranties and representations of the Company contained in Sections 3, 4 and 5 of this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, or any person who controls any Underwriter within the meaning of the Securities Act, or by or on behalf of the Company, its directors and officers, or any person who controls the Company within the meaning of the Securities Act, and shall survive the sale and delivery of the Shares. The Company and each Underwriter agree promptly to notify the others of the commencement of any litigation or proceeding against it and, in the case of the Company, against any of the Company’s officers and directors, in connection with the sale and delivery of the Shares, or in connection with the Registration Statement or Prospectus.

11. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered to Friedman, Billings, Ramsey & Co., Inc., 1001 19th Street North, Arlington, Virginia 22209, Attention: Syndicate Department, with a copy to Morrison & Foerster LLP, 555 West Fifth Street, Suite 3500, Los Angeles, California 90013, Attention: Allen Z.

14. Counterparts and Facsimile Signatures. This Agreement may be signed by the parties in counterparts which together shall constitute one and the same agreement among the parties. A facsimile signature shall constitute an original signature for all purposes.

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 Sections 9 and 10.
