As used in this Agreement, (i) "Preliminary Prospectus" means each prospectus (including all documents incorporated therein by reference) included in that registration statement, or amendments or supplements thereto, before it became effective under the Act, including any prospectus filed with the Commission pursuant to Rule 424(a) of the Rules and Regulations, (ii) "Registration Statement" means that registration statement, as amended or supplemented at the date of the Terms Agreement; (iii) "Basic Prospectus" means the prospectus (including all documents incorporated therein by reference) included in the Registration Statement; and (iv) "Prospectus" means the Basic Prospectus, together with each prospectus amendment or supplement (including in each case all documents incorporated therein by reference) specifically relating to the New Preferred Stock, as filed with, or mailed for filing to, the Commission pursuant to paragraph(b) or (c) of Rule 424 of the Rules and Regulations.

The obligation of the Underwriters to purchase, and the Company to sell, the New Preferred Stock shall be evidenced by a Terms Agreement delivered at the time the Company determines to sell the New Preferred Stock. The Terms Agreement specifies the firm or firms which will be Underwriters, the number of shares of the New Preferred Stock to be purchased by each Underwriter, the purchase price to be paid by the Underwriters for the New Preferred Stock, the public offering price of the New Preferred Stock and any terms of the New Preferred Stock not already specified herein (including, but not limited to, designations, dividend rates, payment dates and redemption provisions). The Terms Agreement specifies any details of the terms of the offering which should be reflected in a post-effective amendment to the Registration Statement or the supplement to the Prospectus relating to the offering of the New Preferred Stock. 3. The Company shall not be obligated to deliver any New Preferred Stock except upon payment for all New Preferred Stock to be purchased pursuant to this Agreement as hereinafter provided. 4. If any one or more of the Underwriters defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriter or Underwriters or such other underwriters satisfactory to the Company who so agree, shall have the right, but shall not be obligated to, purchase in such proportion as may be agreed upon among them, the shares of New Preferred Stock which the defaulting Underwriter failed to purchase. If the non-defaulting Underwriter or Underwriters or other underwriters satisfactory to the non-defaulting Underwriters and the Company do not elect to purchase the New Preferred Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Paragraphs 6(j) and 10 hereof. Nothing contained in this Paragraph 4 shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the New Preferred Stock of the defaulting or withdrawing Underwriter, either the non-defaulting Underwriters or the Company may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, any Prospectus or in any other document or arrangement. 5. Delivery of any payment for the New Preferred Stock shall be made at the office of SBC Warburg Dillon Read, Inc. upon or before the third business day following the date of the Terms Agreement, or at such other location, time and date as shall be agreed upon as specified in the Terms Agreement.

On the Delivery Date, the Company shall deliver the New Preferred Stock to the Underwriters for the account of each Underwriter against payment to or upon the order of the Company of the purchase price by certified or official bank check or checks payable in New York Clearing House funds or by wire transferred immediately available funds, as shall be provided in the Terms Agreement. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. Upon delivery, the New Preferred Stock shall be in definitive fully registered form and in such denominations and registered in such names, as the Underwriters shall request in writing not less than two full business days prior to the Delivery Date. For the purpose of expediting the checking and packaging of the shares of New Preferred Stock the Company shall make the New Preferred Stock available for inspection by the Representative in New York, New York not later than 2:00 P.M., New York City Time, on the business day prior to the Delivery Date. 6.

(a) The Company shall indemnify and hold harmless each Underwriter and its director, officers and each person, if any, who controls any Underwriter within the meaning of the Act from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to which that Underwriter or director, officer or controlling person may become subject, under the Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or any Prospectus or in any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company (any such application, document or information is hereinafter referred to as a "Blue Sky Application") filed in any state or other jurisdiction in order to qualify any or all of the New Preferred Stock under the securities laws thereof, or arises out of, or is 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 shall reimburse each Underwriter, director, officer and controlling person for any legal and other expenses reasonably incurred by such person in investigating or defending or preparing to defend against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action; provided that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, any Prospectus or any Blue Sky Application in reliance upon and in conformity with written information about the Underwriters furnished to the Company by or on behalf of any Underwriter specifically for inclusion therein; and provided further that as to any Preliminary Prospectus this indemnity agreement shall not inure to the benefit of any Underwriter or any director or officer of or person controlling that Underwriter on account of any loss, claim, damage, liability or action arising from the sale of New Preferred Stock to any person by that Underwriter if that Underwriter failed to send or give a copy of any Prospectus, as the same may be amended or supplemented, to that person within the time required by the Act, and the untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact in such Preliminary Prospectus was corrected in such Prospectus, unless such failure resulted from non-compliance by the Company with Paragraph 6(b) hereof. For purposes of the second proviso to the immediately preceding sentence, the term Prospectus shall not be deemed to include the documents incorporated therein by reference, and no Underwriter shall be obligated to send or give any supplement or amendment to any document incorporated by reference in any Preliminary Prospectus or any Prospectus to any person other than a person to whom such Underwriter has delivered such incorporated documents in response to a written request therefor. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or controlling person. (b) Each Underwriter, severally, but not jointly, shall indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and any person who controls the Company within the meaning of the Act from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to which the Company or any such director, officer or controlling person may become subject, under the Act or otherwise, insofar as such loss, claim, damage, liability or action, arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, any Prospectus or any Blue Sky Application, or arises out of, or is 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, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information about the Underwriters furnished to the Company by or on behalf of that Underwriter specifically for inclusion therein, and shall reimburse the Company for any legal and other expenses reasonably incurred by the Company or any such director, officer or controlling person in investigating or defending or preparing to defend against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any of its directors, officers or controlling persons. (c) Promptly after receipt by an indemnified party under this Paragraph of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Paragraph, notify the indemnifying party in writing of the claim or the commencement of that action; provided that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Paragraph 7, except to the extent it has been prejudiced in any material respect by such failure, or from any liability which it may have to an indemnified party otherwise than under this Paragraph. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Paragraph for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided that the indemnified party shall have the right to employ one counsel to represent it and its controlling persons in respect of any claim in respect of which indemnity may be sought by it against the indemnifying party under this Paragraph if, in the reasonable judgment of the indemnified party, it is advisable for it to be represented by separate counsel, and in that event the fees and expenses of such separate counsel shall be paid by the indemnifying party. (d) If the indemnification provided for in this Paragraph 7 shall for any reason be unavailable to an indemnified party under Paragraph 7(a) or 7(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the New Preferred Stock or (ii) 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 on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the New Preferred Stock (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters with respect to such offering, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative 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 contributions pursuant to this Paragraph 7(d) were to be 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 into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Paragraph 7(d) shall be deemed to include, for purposes of this Paragraph 7(d), 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 Paragraph 7(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the New Preferred Stock underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute as provided in this Paragraph 7(d) are several in proportion to their respective underwriting obligations and not joint. (e) The indemnity agreements contained in this Paragraph and the representations, warranties and agreements of the Company in Paragraph 1 and Paragraph 6 hereof shall survive the delivery of the New Preferred Stock and shall be in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 8. The obligations of the Underwriters under this Agreement may be terminated by the Underwriters obligated to purchase a majority of the New Preferred Stock in their absolute discretion, by notice given to and received by the Company prior to the delivery of and payment for the New Preferred Stock, if, during the period beginning on the date of the Terms Agreement to and including the Delivery Date, (a) trading in securities generally on the New York Stock Exchange, Inc., the American Stock Exchange or the over-the-counter market is suspended, or minimum prices are established on either the New York Stock Exchange or the American Stock Exchange, (b) a banking moratorium is declared by either Federal or New York State authorities (c) the United States becomes engaged in material hostilities or there is a material escalation in hostilities involving the United States or there is a declaration of a national emergency or war by the United States, or (d) there shall have been such a material and substantial change in economic, political or financial conditions or the effect of international conditions on the financial markets in the United States shall be so material and substantial, such as, in the reasonable judgment of the Underwriters obligated to purchase a majority of the New Preferred Stock makes it impractical or imprudent to proceed with the payment for and the delivery of the New Preferred Stock. 9. The respective obligations of the Underwriters, under the Agreement with respect to the New Preferred Stock are subject to the accuracy, on the date of the Terms Agreement and on the Delivery Date, of the representations and warranties of the Company contained herein, to performance by the Company of its obligations hereunder, and to each of the following additional terms and conditions applicable to the New Preferred Stock: (a) At or before the Delivery Date, no stop order suspending the effectiveness of the Registration Statement nor any order directed to any document incorporated by reference in any Prospectus shall have been issued and prior to that time no stop order proceeding shall have been initiated or threatened by the Commission and no challenge shall have been made to the accuracy or adequacy of any document incorporated by reference in any Prospectus; any request of the Commission for inclusion of additional information in the Registration Statement or any Prospectus or otherwise shall have been complied with; after the date of the Terms Agreement, the Company shall not have filed with the Commission any amendment or supplement to the Registration statement or any Prospectus (or any document incorporated by reference therein) without the consent of the Underwriters. (b) No Underwriter shall have discovered and disclosed to the Company on or prior to the Delivery Date that the Registration Statement or any Prospectus contains an untrue statement of a fact which, in the opinion of counsel for the Underwriters, is material or omits to state a fact which, in the opinion of such counsel, is material and is required to be stated therein or is necessary to make the statements therein not misleading. (c) All corporate proceedings and other legal matters incident to the authorization, form and validity of this Agreement and the New Preferred Stock and the form of the Registration Statement, each Prospectus (other than financial statements and other financial data) and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be satisfactory in all respects to Cahill Gordon & Reindel, counsel for the Underwriters, and the Company shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.
