If the option is exercised as to all or any portion of the Option Preferred Securities, each of the Underwriters, severally and not jointly, will purchase that proportion of the total number of Option Preferred Securities then being purchased which the number of Initial Preferred Securities each such Underwriter has severally agreed to purchase bears to the total number of Initial Preferred Securities, subject to such adjustments as Merrill Lynch in its discretion shall make to eliminate any sales or purchases of a fractional number of Option Preferred Securities. (c) Payment. Payment of the purchase price for, and delivery of, the Initial Preferred Securities shall be made at the offices of Ballard Spahr Andrews & Ingersoll, LLP, or at such other place as shall be agreed upon by Merrill Lynch and the Trust, at 10:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date of this Underwriting Agreement (unless postponed in accordance with the provisions of Section 10 hereof), or such other time not later than ten business days after such date as shall be agreed upon by Merrill Lynch and the Trust (such time and date of payment and delivery being herein called the "Closing Time"). In addition, in the event that the Underwriters have exercised their option to purchase any or all of the Option Preferred Securities, payment of the purchase price for, and delivery of such Option Preferred Securities, shall be made at the above-mentioned offices of Ballard Spahr Andrews & Ingersoll, LLP, or at such other place as shall be agreed upon by Merrill Lynch and the Trust, on the relevant Date of Delivery as specified in the notice from Merrill Lynch to the Trust. Payment shall be made to the Trust by wire transfer of immediately available funds to a bank account designated by the Trust, against delivery to Merrill Lynch for the respective accounts of the Underwriters of the Preferred Securities to be purchased by them. It is understood that each Underwriter has authorized Merrill Lynch, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Preferred Securities which it has severally agreed to purchase. Merrill Lynch, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Preferred Securities to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder. 13 14 (d) Denominations; Registration. The Preferred Securities shall be in such denominations and registered in such names as Merrill Lynch may request in writing at least one full business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. The Preferred Securities will be made available for examination and, if applicable, packaging by Merrill Lynch in The City of New York not later than 9:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. (e) Compensation. As compensation to the Underwriters for their commitments hereunder and in view of the fact that the proceeds of the sale of the Preferred Securities will be used to purchase Debt Securities of the Company, the Company hereby agrees to pay at the Closing Time or the relevant Date of Delivery, as the case may be, to Merrill Lynch, for the respective accounts of the Underwriters, in immediately available funds, a commission per Preferred Security to be delivered by the Trust at the Closing Time or the relevant Date of Delivery, as the case may be, as is specified in Schedule C hereto. (f) Appointment of Qualified Independent Underwriter. The Trust and the Company hereby confirm their engagement of Merrill Lynch as, and Merrill Lynch hereby confirms their agreement with the Trust and the Company to render services as, a "qualified independent underwriter" within the meaning of Rule 2720 of the Conduct Rules of the National Association of Securities Dealers, Inc. (the "NASD") with respect to the offering and sale of the Preferred Securities. Merrill Lynch, solely in its capacity as qualified independent underwriter and not otherwise, is referred to herein as the "Independent Underwriter". SECTION 3. Covenants. The Trust and the Company covenant with each Underwriter as follows: (a) Compliance with Securities Regulations and Commission Requests. The Trust and the Company, subject to Section 3(b), will comply with the requirements of Rule 430A of the 1933 Act Regulations and/or Rule 434 of the 1933 Act Regulations, if and as applicable, and will notify Merrill Lynch immediately, and confirm the notice in writing, of (i) the effectiveness of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Prospectus, (ii) the receipt of any comments from the Commission, (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Trust and the Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as they deem necessary to ascertain promptly whether the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, they will promptly file the Prospectus. The Trust and the Company will use their best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment. 14 15 (b) Filing of Amendments. The Trust and the Company will give Merrill Lynch notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the 1933 Act Regulations) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish Merrill Lynch with copies of any such document that could reasonably relate to an investment decision for the Preferred Securities a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which Merrill Lynch or counsel for the Underwriters shall reasonably object in writing within 3 days of receipt thereof. (c) Delivery of Registration Statements. The Trust and the Company have furnished or will deliver to Merrill Lynch and counsel for the Underwriters, without charge, a signed copy of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and a signed copy of all consents and certificates of experts, and will also deliver to Merrill Lynch, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters.

The Trust and the Company will deliver to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter may reasonably request, and the Trust and the Company hereby consent to the use of such copies for purposes permitted by the 1933 Act. The Trust and the Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

If at any time when the Prospectus is required by the 1933 Act or the 1934 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Trust and the Company will promptly prepare and file with the Commission, subject to Section 3(b), at the expense of the Company, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Trust and the Company will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as such Underwriters may reasonably request.

For 30 days from the date of this Underwriting Agreement, neither the Trust nor the Company will, without the prior written consent of Merrill Lynch, directly or indirectly, issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise dispose of, (i) preferred securities or any security convertible into or exchangeable for preferred securities substantially similar to the Preferred Securities or any guarantee of such preferred securities or (ii) junior debt securities substantially similar to the Debt Securities, except for the Securities issued pursuant to this Agreement and except with respect to any required remarketing of $200 million of Redeemable Hybrid Income Overnight Shares of Hercules Trust V initially sold on November 12, 1998.

If this Underwriting Agreement is terminated by Merrill Lynch in accordance with the provisions of Section 5 or Section 9(a)(i) hereof, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters. SECTION 5. Conditions of Underwriters' Obligations. The obligations of the Underwriters to purchase and pay for the Preferred Securities pursuant to this Underwriting Agreement are subject to the accuracy of the representations and warranties of the Trust and the Company contained in Section 1 hereof or in certificates of any Trustees of the Trust or any officer of the Company or any of its subsidiaries delivered pursuant to the provisions hereof, to the performance by the Trust and the Company of their covenants and other obligations hereunder, and to the following further conditions: (a) Effectiveness of Registration Statement. The Registration Statement, including any Rule 462(b) Registration Statement, has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement shall have been issued under the 1933 Act and no proceedings for that purpose shall have been instituted or be pending or threatened by the Commission, and any request on the part of the Commission for additional information shall have been complied with to the reasonable satisfaction of counsel to the Underwriters. A prospectus containing information relating to the description of the Preferred Securities, the specific method of distribution and similar matters shall have been filed with the Commission in accordance with Rule 424(b).

(c) Opinion of Special Tax Counsel for the Trust and the Company. At Closing Time, the Company, the Trust and Underwriters shall have received an opinion, dated as of Closing Time, of Ballard Spahr Andrews & Ingersoll, LLP, special tax counsel to the Trust and the Company, that (i) the Debt Securities will be classified for United States federal income tax purposes as indebtedness of the Company, (ii) the Trust will be classified for United States federal income tax purposes as a grantor trust and not as an association taxable as a corporation and (iii) although the discussion set forth in the Prospectus under the heading "Certain Federal Income Tax Consequences" does not purport to discuss all possible United States federal income tax consequences of the purchase, ownership and disposition of the Preferred Securities, such discussion constitutes, in all material respects, a fair and accurate summary of the United States federal income tax consequences of the purchase, ownership and disposition of the Preferred Securities under current law. Such opinion may be conditioned on, among other things, the initial and continuing accuracy of the facts, financial and other information, covenants and representations set forth in certificates of officers of the Company and other documents deemed necessary for such opinion. 18 19 (d) Opinion of Counsel for The Chase Manhattan Bank.

Indemnification. (a) Indemnification of Underwriters. The Trust and the Company, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act from and against any and all losses, claims, damages and liabilities (including, without limitation, the reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted in respect thereof), as incurred, to which such Underwriter or controlling person may be subject, insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus, the Prospectus as amended or supplemented or any amendment or supplement thereto, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, neither the Trust nor the Company shall be liable insofar as such losses, claims, damages or liabilities arise out of or are based upon an untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus or in the Registration Statement or any amendment thereto, the Prospectus, the Prospectus as amended or supplemented or any amendment or supplement thereto in reliance upon and in conformity with information furnished to the Trust and the Company in writing by any Underwriter through the Representatives expressly for use therein; and provided, further, that neither the Trust nor the Company shall be liable to any Underwriter or any person controlling such Underwriter under the indemnity agreement provided for in this Section 6 with respect to a preliminary prospectus to the extent that any such loss, claim, damage or liability of such Underwriter or controlling person results solely from the fact that such Underwriter sold Preferred Securities to a person to whom there was not sent or given, if required by law so to have been delivered, with or prior to the delivery of the written confirmation of such sale, a copy of the Prospectus (excluding documents incorporated by reference) or the Prospectus as then amended or supplemented (excluding documents incorporated by reference), whichever is most recent, if (A) the Trust and the Company have previously furnished copies thereof to such Underwriter a reasonable amount of time in advance of such confirmation and (B) the applicable untrue or alleged untrue statement or omission was corrected therein. In addition to, and without limitation of, the joint and several obligation of the Trust and the Company to indemnify Merrill Lynch as an Underwriter, the Trust and the Company, jointly and severally, also agree to indemnify and hold harmless the Independent Underwriter and each person, if any, who controls the Independent Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense, as incurred, incurred as a result of the Independent Underwriter's participation as a "qualified independent underwriter" within the meaning of Rule 2720 of the Conduct Rules of the NASD in connection with the offering of the Preferred Securities. (b) Indemnification of Company, Directors and Officers and the Trust and Trustees. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, the Trust, the Trustees 22 23 and each person, if any, who controls the Company or the Trust within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act from and against any and all losses, claims, damages and liabilities (including, without limitation, the reasonable legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted in respect thereof), as incurred, to which the Company or the Trust may become subject, insofar as such losses, claims, damages or liabilities arise out of or are based upon untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement or any amendment thereto, any preliminary prospectus or the Prospectus, the Prospectus as amended or supplemented or any amendment or supplement thereto in reliance upon and in conformity with information furnished to the Trust and the Company in writing by such Underwriter through the Representatives expressly for use therein. (c) Actions against Parties; Notification. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought (the "Indemnified Person") pursuant to either of subsections (a) or (b) above, such Indemnified Person shall promptly notify the person against whom such indemnity may be sought (the "Indemnifying Person") in writing (in such detail as may be available to such Indemnified Person). In no case shall an Indemnifying Person be liable under this Section 6 with respect to any claim made against an Indemnified Person unless such Indemnifying Person shall be notified in writing of the nature of the claim within a reasonable time after the Indemnified Person is aware of such claim thereof, but failure so to notify such Indemnifying Person shall not relieve it from any liability which it may have otherwise than on account of this Section 6. Upon such notice, the Indemnifying Person shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other Indemnifying Person similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Person, and after notice from the Indemnifying Person to such Indemnified Person of its election so to assume the defense thereof, the Indemnifying Person shall not be liable to such Indemnified Person for any legal or other expenses subsequently incurred by such Indemnified Person in connection with the defense thereof other than reasonable costs of investigation or as provided in the next succeeding paragraph. Each Indemnified Person shall assist the Indemnifying Person in any defense undertaken pursuant to this Section 6 by providing such assistance and cooperation (including, without limitation, witness and documentary or other information) as may be reasonably requested by the Indemnifying Person in connection with such defense, provided that all reasonable costs and expenses of such assistance and cooperation shall be borne by the Indemnifying Person. Notwithstanding anything to the contrary herein contained, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in the applicable suit, action, proceeding, claim or demand (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or defenses available to them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) retained by the Indemnified Persons in accordance with the preceding 23 24 sentence, and that all such fees and expenses, to the extent they are reasonable, shall be reimbursed as they are incurred, subject to the provisions of the succeeding paragraph. Any such separate firm for the Underwriters and controlling persons of the Underwriters shall be designated in writing by Merrill Lynch and any such separate firm for the Company, its directors, its officers who sign the Registration Statement, the Trust, the Trustees and controlling persons of the Company or the Trust shall be designated in writing by the Company. Notwithstanding anything to the contrary contained herein, if indemnity is sought pursuant to the second paragraph of Section 6(a), then, in addition to the fees and expenses of counsel for the Indemnified Persons, the Indemnifying Person shall be not liable for the fees and expenses of more than one firm (in addition to any local counsel) separate from its own counsel and that of the other Indemnified Persons for the Independent Underwriter in its capacity as a "qualified independent underwriter" and all persons, if any, who control the Independent Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of 1934 Act in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances if, in the reasonable judgment of the Independent Underwriter, there may exist a conflict of interest between the Independent Underwriter and the other Indemnified Persons. Any such separate counsel for the Independent Underwriter and such control persons of the Independent Underwriter shall be designated in writing by the Independent Underwriter. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for any Indemnified Person, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested an Indemnifying Party to reimburse the Indemnified Party for fees and expenses of counsel, the Indemnifying Party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such Indemnifying Party of the aforesaid request and (ii) such Indemnifying Party shall not have reimbursed the Indemnified Party in accordance with such request prior to the date of such settlement. Notwithstanding the immediately preceding sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel, an Indemnifying Person shall not be liable for any settlement referred to in such sentence effected without its consent if such Indemnifying Person (i) reimburses such Indemnified Person in accordance with such request to the extent it considers such request to be reasonable and (ii) provides written notice to the Indemnified Person substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement No Indemnifying Person shall, without the prior written consent of all Indemnified Persons, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 (whether or not the Indemnified Persons are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnified Person from all liability arising out of such litigation, 24 25 investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. SECTION 7. Contribution. If the indemnification provided for in Section 6 is unavailable or insufficient to an Indemnified Person in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under Section 6, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Trust and the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Preferred Securities 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 Trust and the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Trust and the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Preferred Securities shall be deemed to be in the same respective proportions as the total proceeds from the offering of such Preferred Securities (before deducting expenses) received by the Trust (net of the amount of the total underwriting discount paid by the Company) and the total underwriting discounts received by the Underwriters, in each case as set forth on the cover page of the Prospectus, bear to the aggregate initial public offering price of such Preferred Securities as set forth on such cover page. The relative fault of the Trust and the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Trust or 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. With respect to any Underwriter, such relative fault shall also be determined by reference to the extent (if any) to which such losses, claims, damages or liabilities (or actions in respect thereof) with respect to any preliminary prospectus result from the fact that such Underwriter sold Preferred Securities to a person to whom there was not sent or given, if required by law so to have been delivered, with or prior to the delivery of the written confirmation of such sale, a copy of the Prospectus (excluding documents incorporated by reference) or of the Prospectus as then amended or supplemented (excluding documents incorporated by reference) if (A) the Company has previously furnished copies thereof to such Underwriter a reasonable amount of time in advance of such confirmation and (B) the applicable untrue or alleged untrue statement or omission was corrected therein. The Trust, the Company and the Underwriters agree that Merrill Lynch will not receive any additional benefits hereunder for serving as the Independent Underwriter in connection with the offering and sale of the Preferred Securities. The Trust, the Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even 25 26 if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the two immediately preceding paragraphs. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Preferred Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of any such 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, each Trustee and each person, if any, who controls the Company or the Trust within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company and the Trust. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of the Initial Preferred Securities set forth opposite their names in the Schedule A hereto, and not joint. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Underwriting Agreement or in certificates of Trustees of the Trust or officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect for the period contemplated by the applicable statute of limitations, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Trust or the Company, and shall survive delivery of and payment for the Preferred Securities. SECTION 9. Termination. (a) Termination. The Representatives may terminate this Underwriting Agreement, by notice to the Trust and the Company, at any time at or prior to the Closing Time or any relevant Date of Delivery, if (i) there has been, since the time of execution of this Underwriting Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in or affecting the earnings, business or operations of the Trust or the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change in national or international political, financial or economic conditions, in each case the effect of which is such 26 27 as to make it, in the judgment of the Representatives, impracticable to market the Preferred Securities or to enforce contracts for the sale of the Preferred Securities, or (iii) trading in any securities of the Trust or the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange or the American Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (iv) a banking moratorium has been declared by either Federal or New York authorities. (b) Liabilities. If this Underwriting Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or the relevant Date of Delivery, as the case may be, to purchase the Preferred Securities which it or they are obligated to purchase under this Underwriting Agreement (the "Defaulted Securities"), then Merrill Lynch shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, Merrill Lynch shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the number of Preferred Securities to be purchased on such date pursuant to this Underwriting Agreement, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations under this Underwriting Agreement bear to the underwriting obligations of all non-defaulting Underwriters, or (b) if the number of Defaulted Securities exceeds 10% of the number of Preferred Securities to be purchased on such date pursuant to this Underwriting Agreement, this Underwriting Agreement (or, with respect to the Underwriters' exercise of the over-allotment option for the purchase of Option Preferred Securities on a Date of Delivery after the Closing Time, the obligations of the Underwriters to purchase, and the Company to sell, such Option Preferred Securities on such Date of Delivery) shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in (i) a termination of this Underwriting Agreement or (ii) in the case of a Date of Delivery after the Closing Time, a termination of the obligations of the Underwriters and the Company with respect to the related Option Preferred Securities, as the case may be, either Merrill Lynch or the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a 27 28 period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. SECTION 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

This Underwriting Agreement shall each inure to the benefit of and be binding upon the Trust, the Company, the Underwriters and their respective successors. Nothing expressed or mentioned in this Underwriting Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Trust and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Underwriting Agreement or any provision herein contained. This Underwriting Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Preferred Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase. SECTION 13. GOVERNING LAW AND TIME.
