                              AVAILABLE INFORMATION

         We are subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and, in accordance
therewith, we file reports, proxy statements and other information with the
Commission. Such reports, proxy statements and other information may be
inspected and copied at the public reference facilities maintained by the
Commission at Room 1024, 450 Fifth Street, N.W., Washington, D.C. 20549 and at
the Commission's regional offices at 7 World Trade Center, 13th Floor, Suite
1300, New York, New York 10048 and Suite 1400, Citicorp Center, 500 West Madison
Street, Chicago, Illinois 60661. You may also obtain copies of such material by
mail from the Public Reference Section of the Commission at 450 Fifth Street,
N.W., Washington, D.C. 20549 at prescribed rates. If available, you may also
access such information through the Commission's electronic data gathering,
analysis and retrieval system, commonly referred to as EDGAR, via electronic
means, including the Commission's home page on the Internet
(http://www.sec.gov). Our common stock is traded on the Nasdaq National Market
under the symbol "BFOH." You may inspect the reports, proxy statements and other
information concerning us at the offices of the National Association of
Securities Dealers, Inc., 1735 K Street, N.W., Washington D.C. 20006.

         No separate financial statements of the Trust have been included in
this prospectus and no separate financial statements will be prepared in the
future. We do not consider that such financial statements would be material to
holders of the securities offered by this prospectus because the Trust is a
newly-formed special purpose entity, has no operating history or independent
operations, is not engaged in and does not propose to engage in any activity
other than holding as trust assets our junior subordinated debentures, issuing
the capital and common securities and engaging in incidental activities. The
obligations of the Trust under the capital securities are fully and
unconditionally guaranteed by us to the extent the Trust has funds available to
meet such obligations. We do not expect that the Trust will file reports, proxy
statements and other information under the Exchange Act with the Commission.

         This prospectus constitutes a part of a registration statement on Form
S-4 filed by us and the Trust with the Commission under the Securities Act. This

regulations of the Commission. We are referring you to the registration
statement and to the exhibits for further information with respect to us, the
Trust and the exchange securities. The statements contained in this prospectus
concerning the provisions of any document are not necessarily complete, and, in
each instance, we refer you to the copy of such document filed as an exhibit to
the registration statement or otherwise filed with the Commission. Each such
statement is qualified in its entirety by such reference.

         -  changes in the Small Business Administration's ("SBA") lending
            program;
         -  the impact of competitive products, services and pricing; and
         -  legislative, regulatory and accounting changes affecting the banking
            and financial services industry.

         Our actual results could vary materially from the future results
covered in our forward-looking statements. The statements in the "Risk Factors"
section are cautionary statements identifying important factors, including
certain risks and uncertainties, that could cause our results to vary materially
from the future results covered in such forward-looking statements. Other
factors, such as the general state of the United States economy, could also

forward-looking statements. We disclaim any obligation to announce publicly
future events or developments that affect the forward-looking statements in this

                                    SUMMARY

The following summary contains the basic information about this exchange offer.
It does not contain all of the information that may be important to you in
deciding whether to exchange your old securities for new securities. We
encourage you to read the prospectus in its entirety.


                              BANCFIRST OHIO CORP.

         We are a registered bank holding company, organized under the laws of
the State of Ohio. We conduct a full-service commercial and retail banking
business through our wholly-owned subsidiary, The First National Bank of
Zanesville. Effective May 16, 1998, we merged our two other banking
subsidiaries, Bellbrook Community Bank and County Savings Bank, with First
National under its national bank charter. In April 1999, we also acquired
Chornyak & Associates, Inc., a full service financial planning company.

         We are headquartered in Zanesville, Ohio, the county seat of Muskingum
County. Through First National, we operate 22 full-service banking facilities
which serve Muskingum, Licking, Franklin and Greene Counties of Ohio. Our
primary market extends along Interstate 70 in central Ohio and includes the
areas of Zanesville, Newark, Columbus, and Dayton. Our principal executive
office is located at 422 Main Street, Zanesville, Ohio 43702. Our telephone
number is (740) 452-8444.

          Our focus is on providing personalized, high quality and comprehensive
banking services in order to develop and maintain long-term relationships with
our customers. We offer a range of banking services, including:

         -  commercial and commercial real estate loans;
         -  SBA loans;
         -  residential real estate loans;
         -  consumer loans;
         -  personal and business checking accounts;
         -  savings accounts;
         -  demand and time deposits;
         -  safe deposit services; and
         -  trust, private banking, financial planning and investment services.

         At September 30, 1999, on a consolidated basis, we had total assets of
$1.2 billion, total liabilities of $1.2 billion, which included total deposits
of $789.3 million, total loans of $830.2 million, and total stockholders' equity
of $83.6 million.

                              BFOH CAPITAL TRUST I

         BFOH Capital Trust I is a statutory business trust created under
Delaware law upon the filing of a certificate of trust with the Delaware
Secretary of State. The Trust's business and affairs are conducted by the
property trustee, the Delaware trustee and the three individual administrative
trustees, who are officers of BancFirst Ohio. The Trust exists for the exclusive
purposes of:

         -  issuing and selling the capital securities discussed below;
         -  using the proceeds from the sale of the original capital securities
            to acquire the junior subordinated debentures issued by BancFirst
            Ohio; and
         -  engaging in only those other activities necessary, advisable or
            incidental to the above.

Accordingly, the junior subordinated debentures are the sole assets of the

                              THE EXCHANGE OFFERING

         On October 18, 1999, we privately placed $20.0 million aggregate
liquidation amount of 9.875% Capital Securities, Series A, of BFOH Capital Trust
I. We provided a guarantee for the capital securities, as described in this

         Under that registration rights agreement, we must use our reasonable
best efforts to complete this exchange offer within 30 days after the effective
date of the registration statement of which this prospectus is a part, which
effective date must occur on or prior to April 15, 2000. If we do not complete
this exchange offer before that date, we must pay liquidated damages until the

outstanding capital securities for our 9.875% Capital Securities, Series B, to
be issued in the exchange offer which have substantially the same terms. You
should read the discussion under the heading "The Exchange Offer" and
"Description of the Securities" for further information regarding the exchange
capital securities to be issued in the exchange offer.

SECURITIES OFFERED..............    $20.0 million in liquidation amount of new
                                    9.875% Capital Securities, Series B, of BFOH
                                    Capital Trust I, which have been registered

                                    offered in the exchange offer are
                                    substantially identical to those of the
                                    outstanding capital securities, except that
                                    certain transfer restrictions, registration
                                    rights and liquidated damages provisions
                                    relating to the outstanding capital
                                    securities do not apply to the new
                                    registered capital securities.

THE EXCHANGE OFFER..............    We are offering to issue registered exchange

                                    offering to issue these registered exchange
                                    capital securities and to satisfy our
                                    obligations under the registration rights
                                    agreement with the initial purchaser. You
                                    may tender your outstanding capital
                                    securities for exchange by following the

                                    Exchange Offer."

                                      are not engaging in, and do not intend to
                                      engage in, a distribution of the new
                                      securities. You may withdraw your tender

                                      exchange, we will return them to you

                                      exchange offer expires or terminates.

CONDITIONS TO THE
EXCHANGE OFFER......................  We are not required to accept any old
                                      securities in exchange for new securities.
                                      We may terminate or amend the exchange
                                      offer if we determine that the exchange
                                      offer violates applicable law or any
                                      applicable SEC interpretation.

FEDERAL TAX
CONSEQUENCES........................  The exchange of outstanding capital
                                      securities for new capital securities
                                      under the exchange offer will not result
                                      in any gain or loss to you for federal
                                      income tax purposes.

USE OF PROCEEDS.....................  We will not receive any proceeds from the
                                      exchange offer.

ACCRUED INTEREST....................  The new securities will bear interest from
                                      October 18, 1999, the date the old
                                      securities were originally issued. No
                                      interest will be paid on the old
                                      securities following their acceptance for
                                      exchange. See "Description of the
                                      Securities."

EXCHANGE AGENT......................  Wilmington Trust Company, as property
                                      trustee, is the exchange agent for the
                                      exchange offer. The address and telephone
                                      number of the exchange agent are set forth
                                      under the heading "The Exchange Offer - -
                                      Exchange Agent."

                       CONSEQUENCES OF NOT EXCHANGING YOUR
                         OUTSTANDING CAPITAL SECURITIES

         If you do not exchange your outstanding capital securities in the
exchange offer, they will continue to be subject to the restrictions on transfer
that are described in the legend on the capital securities. In general, you may
offer or sell your outstanding capital securities only if they are registered
under, or offered or sold under an exemption from, the Securities Act of 1933,
and applicable state securities laws.

         If outstanding capital securities are tendered and accepted in the
exchange offer, it may become more difficult for you to sell or transfer your
unexchanged capital securities. In addition, if you do not exchange your
outstanding capital securities in the exchange offer, you will no longer be
entitled to have those capital securities registered under the Securities Act,
except in limited circumstances with respect to specific types of holders of
outstanding capital securities. See "The Exchange Offer - - Consequences of
Failure to Exchange Outstanding Securities."

                         CONSEQUENCES OF EXCHANGING YOUR
                         OUTSTANDING CAPITAL SECURITIES

         Based on interpretations of the staff of the SEC, we believe that you
may offer for resale, resell or otherwise transfer the new securities that we
issue in the exchange offer without complying with the registration and
prospectus delivery requirements of the Securities Act if:

         -  you acquire the new securities issued in the exchange offer in the
            ordinary course of business;

         -  you are not participating, do not intend to participate, and have no
            arrangement or undertaking with anyone to participate, in the
            distribution of the new securities issued to you in the exchange
            offer; and

         -  you are not an "affiliate" of BancFirst Ohio Corp., as defined in
            Rule 405 of the Securities Act.

         If any of these conditions are not satisfied and you transfer any new
securities issued to you in the exchange offer without delivering a proper
prospectus or without qualifying for a registration exemption, you may incur
liability under the Securities Act. We will not be responsible for or indemnify
you against any liability you may incur.

         Any broker-dealer that acquires new securities in the exchange offer
for its own account in exchange for old securities, which it acquired through
market-making or other trading activities, must acknowledge that it will deliver
a prospectus when it resells or transfer any new securities issued in the
exchange offer. See "Plan of Distribution."

                    SUMMARY DESCRIPTION OF THE NEW SECURITIES

         The form and terms of the new securities to be issued in the exchange
are the same as the form and terms of the old securities except that the new
securities to be issued in the exchange offer have been registered under the
Securities Act and, therefore, will not bear legends restricting their transfer
and will not contain the registration rights and liquidated damages provisions
contained in the old securities. The new securities will evidence the same
beneficial ownership interests as the old securities and both the new capital
securities and the old capital securities are governed by the same Trust
Agreement.

         The following is a brief summary of select terms of the new securities.
For a more complete description of the terms of the new securities, see
"Description of the Capital Securities."


OUTSTANDING SECURITIES..............  $20,000,000 of 9.875% Capital Securities,
                                      Series A (liquidation amount $1,000 per
                                      capital security).

DISTRIBUTIONS.......................  You are entitled to receive cumulative
                                      cash distributions at the annual rate of
                                      9.875% of the liquidation amount of $1,000
                                      per capital security. Distributions
                                      accumulate from October 18, 1999 and will
                                      be paid semi-annually in arrears on April
                                      15 and October 15 of each year beginning
                                      on April 15, 2000. The amount of each
                                      distribution will include amounts accrued
                                      up to the date the distribution is due.

DEFERRAL PERIODS....................  So long as no event of default under the
                                      junior subordinated debentures has
                                      occurred and is continuing, we have the
                                      right, at one or more



                                       8

                                      times, to defer interest payments on the
                                      junior subordinated debentures for up to
                                      10 consecutive semi-annual periods, which
                                      deferral will end on an interest payment
                                      date, but not beyond October 15, 2029, the
                                      stated maturity date of the junior
                                      subordinated debentures.

                                      If we defer interest payments on the
                                      junior subordinated debentures, the Trust
                                      will also defer distributions on the
                                      capital securities. During this deferral
                                      period, the junior subordinated debentures
                                      will continue to accrue interest and the
                                      capital securities will continue to
                                      accumulate distributions. During a
                                      deferral period you will also accumulate
                                      additional distributions at the annual
                                      rate of 9.875% on any accrued and unpaid
                                      distributions, to the extent permitted by
                                      law. If the Trust defers your
                                      distributions, you will still be required
                                      to accrue interest income and include it
                                      in your gross income for U.S. federal
                                      income tax purposes, even if you are a
                                      cash basis taxpayer.

RANKING.............................  Our obligations under the junior
                                      subordinated debentures are unsecured and
                                      subordinated to payment of our senior and
                                      subordinated debt, to the extent and in
                                      the manner set forth in the indenture, and
                                      will be effectively subordinated to all of
                                      the existing and future liabilities and
                                      obligations of our subsidiaries, including
                                      First National's deposit liabilities. At
                                      September 30, 1999, we had senior debt
                                      outstanding totaling $6.25 million.

GUARANTEE...........................  We have, on a subordinated basis, fully,
                                      irrevocably and unconditionally
                                      guaranteed:

                                      -  payment of distributions on the
                                         capital securities;

                                      -  payments on liquidation of the Trust;
                                         and

                                      -  payments on maturity or earlier
                                         redemption of the capital securities.

                                      If we do not make a payment on the junior
                                      subordinated debentures, the Trust will
                                      not have sufficient funds to make payments
                                      on the capital securities. Our guarantee
                                      does not assure the payment of
                                      distributions when the Trust does not have
                                      sufficient funds to pay the distributions.
                                      Our obligations under the guarantee are
                                      unsecured and are subordinated and junior
                                      to the payment of our senior and
                                      subordinated debt and will be effectively
                                      subordinated to all of the existing and
                                      future liabilities and obligations of our
                                      subsidiaries.

DISTRIBUTION OF JUNIOR
   SUBORDINATED DEBENTURES..........  At any time, we have the right, subject
                                      to receipt of any required regulatory
                                      approval, to liquidate the Trust and cause
                                      the junior subordinated debentures to be
                                      distributed to holders of capital
                                      securities and common securities in
                                      liquidation of the Trust. The junior
                                      subordinated debentures will have the
                                      identical terms and conditions as the
                                      capital securities.

                                      If we elect to liquidate the Trust and

                                      securities when we pay the junior

                                      Our ability to redeem some or all of the
                                      junior subordinated debentures on or after
                                      October 15, 2009, is subject to certain
                                      conditions. In addition, we may redeem the
                                      junior subordinated debentures at our
                                      option, in whole but not in part:

                                      -  if certain tax events occur;
                                      -  if there is a change in the way the
                                         junior subordinated debentures are
                                         treated for regulatory capital
                                         purposes; or
                                      -  if there is a change in the Investment

                                         Trust to register under that law.

                                      We may have to obtain regulatory
                                      approvals, including the approval of the
                                      Federal Reserve Board, before we redeem
                                      any junior subordinated debentures prior
                                      to maturity. If we redeem the junior
                                      subordinated debentures, you will receive
                                      the liquidation amount of $1,000 per

                                      unpaid distributions to the date of
                                      redemption.

ABSENCE OF MARKET FOR THE
    CAPITAL SECURITIES..............  The capital securities are a new issue of
                                      securities for which currently there is no
                                      market. Although the initial purchaser
                                      intends to make a market in the capital
                                      securities and the exchange capital
                                      securities, the initial purchaser is not
                                      obligated to do so, and any such market
                                      making may be discontinued at any time
                                      without notice. We do not intend to seek a
                                      listing of the capital securities or the
                                      exchange capital securities, on any
                                      national securities exchange or on the
                                      Nasdaq Stock Market. The capital
                                      securities are eligible for quotation on
                                      the Private Offering, Resales and Trading
                                      through Automated Linkages ("PORTAL")

USE OF PROCEEDS.....................  All of the proceeds from the sale by the
                                      Trust of its original capital securities
                                      and common securities were invested by the
                                      Trust in our junior subordinated
                                      debentures. We currently intend to use the
                                      net proceeds from the sale of the junior
                                      subordinated debentures, which was
                                      approximately $19.2 million, net of
                                      commissions and other offering expenses,
                                      for general corporate purposes, such as
                                      the repurchase of our common stock and the
                                      purchase of securities by our banking
                                      subsidiary, which may include long-term
                                      securities. We have initially invested the
                                      net proceeds in short-term investment
                                      grade financial securities. We will not
                                      receive any proceeds from the exchange
                                      offer.

                               RECENT DEVELOPMENTS

         On January 13, 2000, we entered into an agreement to acquire Milton
Federal Financial Corporation, by merging Milton into us. Under the terms of the
agreement, we will exchange .444 shares of our common stock and $6.80 for each
of the 2,099,995 outstanding shares of Milton. We will redeem Milton's
outstanding stock options for cash equal to the acquisition price per share less
the exercise price of the options prior to closing. Based on our closing price
of $20.375 on January 12, 2000, the transaction would be valued at $33.3
million. We will account for the merger as a purchase. We expect to consummate
the merger in the second quarter of 2000, pending approval by Milton's
shareholders, regulatory approval and other customary conditions of closing.
Milton has granted us an option to purchase up to 19.9% of Milton's outstanding
shares upon the occurrence of certain events.

         At September 30, 1999, Milton had total assets of $256.7 million,
deposits of $168.5 million and shareholders' equity of $25.0 million. For the
twelve months ended September 30, 1999, Milton reported net income of $1.6
million with a return on assets of 0.63% and a return on shareholders' equity of
6.19%.

(4)      Interest rate spread represents the difference between the weighted
         average yield on interest earning assets and the weighted average cost
         of interest-bearing liabilities, and net interest margin represents net
         interest income as a percentage of average interest-earning assets.
(5)      Excludes amortization of intangibles and non-recurring charges totaling

         though on accrual status, and had a specific reserve assigned to it in
         the amount of $448. Including restructured loans, the Company's asset
         quality ratios at September 30, 1999 would be as follows:
         non-performing loans plus restructured loans to total loans, 0.80%;
         non-performing assets plus restructured loans to total assets, 0.58%;
         allowance for possible loan losses to non-performing loans plus

(9)      For purposes of computing the ratios of earnings to fixed charges,
         earnings represent net income from continuing operations plus total
         taxes based on income and fixed charges. Fixed charges, excluding
         interest on deposits, include interest expense (other than on
         deposits), one-third (the proportion deemed representative of the
         interest factor) of rents, net of income from subleases and capitalized
         interest. Fixed charges, including interest on deposits, include all
         interest expense, one-third (the proportion deemed representative of
         the interest factor) of rents, net of income from subleases, and
         capitalized interest.

                                  RISK FACTORS

       You should carefully read the following risk factors and other sections
of this prospectus before exchanging your capital securities. You should
carefully consider all of these risk factors to be important.


RISKS RELATED TO THE EXCHANGE OFFER AND YOUR INVESTMENT IN THE CAPITAL
SECURITIES

YOU MAY HAVE DIFFICULTY SELLING THE OLD SECURITIES WHICH YOU DO NOT EXCHANGE

         If you do not exchange your old securities for the new securities
offered in this exchange offer, you will continue to be subject to the
restrictions on the transfer of your old securities. Those transfer restrictions
are described in the trust agreement and in the legend contained on the old
securities, and arose because the old securities were originally issued under
exemptions from, and in transactions not subject to, the registration
requirements of the Securities Act. Except in limited circumstances with respect
to specific types of holders of old securities, we will have no further
obligation to provide for registration under the Securities Act of the old
securities upon completion of the exchange offer.

         In general, you may offer or sell your old securities only if they are
registered under the Securities Act and applicable state securities laws, or if
they are offered and sold under an exemption from those requirements. We do not
intend to register the old securities under the Securities Act.

         If a large number of old securities are exchanged for new securities
issued in the exchange offer, it may be more difficult for you to sell your
unexchanged capital securities. See "The Exchange Offer -- Consequences of
Failure to Exchange Outstanding Securities" for a discussion of the possible
consequences of failing to exchange your old securities.

BANCFIRSTOHIO CANNOT MAKE PAYMENTS UNDER THE GUARANTEE OR THE JUNIOR
     SUBORDINATED DEBENTURES IF BANCFIRST OHIO WOULD DEFAULT ON ITS OTHER
     OBLIGATIONS THAT ARE MORE SENIOR.

         Our obligations under the guarantee issued for your benefit are
         unsecured and rank

         -        junior to all of our other borrowings, except those borrowings
                  that by their terms are equal or junior;

         -        junior to all of First National's deposit accounts; and

         -        senior to our common stock.

         This means that we cannot pay under the guarantee if we default on
payments of any of our other borrowings, unless, by their terms, those
borrowings are equal or junior to the guarantee. If we liquidate, go bankrupt or
dissolve, we would be able to pay under the guarantee only after we have paid
all our other liabilities that are senior to the guarantee.

         Our obligations under the junior subordinated debentures are unsecured
and rank junior in priority to all of our senior indebtedness, which includes
our borrowings that are not by their terms equal or junior to the junior
subordinated debentures. If we default on a payment on our senior indebtedness,
we cannot pay principal or interest on the junior subordinated debentures. If we
liquidate, go bankrupt or dissolve, we would be able to pay the Trust under the
junior subordinated debentures only after we have made all payments on our
senior indebtedness. As of September 30, 1999, we had approximately $6.25
million in senior indebtedness, excluding insured deposits.



                                       14
<PAGE>   16

         If we default on our obligations to pay principal, premium or interest
on the junior subordinated debentures, the Trust will not have sufficient funds
to make distribution payments or liquidation payments on the capital securities.
As a result, you will not be able to rely upon our guarantee for payment of
these amounts. Instead, you or the property trustee may enforce the rights of
the Trust under the junior subordinated debentures against us. For more
information, please refer to "Description of Subordinated Debentures -
Enforcement of Certain Rights by Holders."

         The capital securities, guarantee, the junior subordinated debentures
and the indenture do not limit our ability to incur additional debt, including
debt that is senior in priority of payment.

         For more information on payments under the guarantee and the junior
subordinated debentures, you should refer to "Description of Guarantee -- Status
of the Guarantee" and "Description of Junior Subordinated Debentures -
Subordination."

BANKING LAWS AND REGULATIONS LIMIT BANCFIRST OHIO'S ACCESS TO FUNDS, WHICH MAY
         PREVENT BANCFIRST OHIO FROM MAKING PAYMENTS UNDER THE SUBORDINATED
         DEBENTURES.

         We are a banking holding company regulated by the Federal Reserve
Board, or FRB, and almost all of our operating assets are owned by First
National. We rely primarily on dividends from First National to meet our
obligations for payment of principal and interest on our outstanding debt
obligations and corporate expenses. Dividend payments from First National are
subject to regulatory limitations, generally based on current and retained
earnings, imposed by the various regulatory agencies with authority over First
National. Payment of dividends is also subject to regulatory restrictions if
such dividends would impair the capital of First National. Payment of dividends
by First National is also subject to First National's profitability, financial
condition and capital expenditures and other cash flow requirements. Bank
regulatory agencies have authority to prohibit First National or us from
engaging in an unsafe or unsound practice in conducting their business. The
payment of dividends, depending upon the financial condition of First National
or us, could be deemed to constitute such an unsafe or unsound practice. The FRB
has stated that, as a matter of prudent banking, a bank or bank holding company
should not maintain its existing rate of cash dividends on common stock unless:

         -        the organization's net income available to common shareholders
                  over the past year has been sufficient to fund fully the
                  dividends; and

         -        the prospective rate of earnings retention appears consistent
                  with the organization's capital needs, asset quality, and
                  overall financial condition.

         No assurance can be given that First National will be able to pay
dividends at past levels, or at all, in the future. See the section entitled
"Regulation and Supervision" in our Annual Report on Form 10-K for the year
ended December 31, 1998, which is incorporated herein by reference.

         In addition to regulatory restrictions on the payment of dividends,
First National is subject to certain restrictions imposed by federal law on any
extensions of credit it makes to its affiliates and on investments in stock or
other securities of its affiliates. We are considered an affiliate of First
National. These restrictions prevent affiliates of First National, including us,
from borrowing from First National, unless various types of collateral secure
the loans. Federal law limits the aggregate amount of loans to and investments
in any single affiliate to 10% of the bank's capital and surplus and also limits
the aggregate amount of loans to and investments in all affiliates to 20% of the
bank's capital and surplus. As of September 30, 1999, approximately $8.4 million
of credit was available to us under this limitation.



                                       15
<PAGE>   17

         Under the prompt corrective action provisions of the Federal Deposit
Insurance Act, First National is prohibited from making capital distributions,
including the payment of dividends, if, after making any capital distribution,
First National would become undercapitalized as defined under the Federal
Deposit Insurance Act. Based on First National's current financial condition, we
do not expect that this provision will have any impact on our ability to obtain
dividends from First National; however, we cannot be sure that First National
will be able to pay dividends in the future. At September 30, 1999, First
National had the capital to pay us $6.2 million in dividends without requiring
regulatory approval.

         If we do not receive sufficient cash dividends from First National,
then it is unlikely that we will have sufficient funds to make payments on the
junior subordinated debentures, thereby leaving insufficient funds for the Trust
to make payments to you on the capital securities.

BANCFIRSTOHIO CAN DEFER INTEREST PAYMENTS ON THE JUNIOR SUBORDINATED DEBENTURES,
         CAUSING YOUR PAYMENTS UNDER THE CAPITAL SECURITIES TO STOP, WHICH WILL
         HAVE TAX CONSEQUENCES TO YOU AND MAY AFFECT THE MARKET PRICE OF THE
         CAPITAL SECURITIES.

         We have the right, at one or more times, unless an event of default
exists under the junior subordinated debentures, to defer interest payments on
the junior subordinated debentures for up to 10 consecutive semi-annual periods,
but not beyond October 15, 2029. If we defer interest payments, the Trust will
defer paying distributions to you on your capital securities during the deferral
period. Additionally, during this period, any unpaid distributions on the
capital securities will accumulate additional distributions at the rate of
9.875% per year, compounded semi-annually, to the extent permitted by law. We
also will be prohibited from declaring or paying cash dividends on our common
stock. For more information, please refer to "Description of Capital Securities
- - Distributions."

         When any deferral period ends and we pay all interest then accrued and
unpaid on the junior subordinated debentures, we may elect to begin a new
deferral period. There is no limitation on the number of times that we may elect
to begin a deferral period. See "Description of Capital Securities -
Distributions" and "Description of Junior Subordinated Debentures - Options to
Extend Interest Payment Date."

         If we exercise our right to defer payments of interest on the junior
subordinated debentures, you will be required to accrue income (as original
issue discount) in respect of the deferred stated interest allocable to your
capital securities for U.S. federal income tax purposes, which will be allocated
but not distributed to you. As a result, you will be required to recognize
income for U.S. federal income tax purposes before you receive any cash and will
not receive the cash related to this interest income from the Trust if you
dispose of your capital securities prior to the record date for the distribution
payment.

         We do not currently intend to exercise our right to defer interest
payments on the junior subordinated debentures. However, if we exercise this
right in the future, the market price of the capital securities will probably be
affected. The capital securities may trade at a price that does not fully
reflect the value of accrued but unpaid interest on the junior subordinated
debentures. If you sell your capital securities during a deferral period, you
may not receive the same return on your investment as someone else who continues
to hold the capital securities. As a result of our right to defer interest
payments, the market price of the capital securities, which represent preferred
beneficial interests in the Trust, may be more volatile than the market prices
of other securities that are not subject to such deferral options.

THE TRUST MAY REDEEM THE CAPITAL SECURITIES IF A SPECIAL EVENT OCCURS.

         If there are changes in the bank regulatory, investment company or tax
laws prior to October 15, 2009, that would adversely affect the status of the
Trust, the capital securities or the junior subordinated debentures, we have the
right to redeem the junior subordinated debentures, in whole but not in part.
Our redemption of the junior subordinated debentures will cause the Trust to
redeem the capital securities prior to maturity.

         Our ability to cause the redemption of the capital securities under
these circumstances is subject to us receiving the necessary regulatory
approval, if required. For more information concerning events which may cause
the redemption of the junior subordinated debentures and prepayment of the
capital securities, see "Description of the capital securities - Redemption."

IF WE DISTRIBUTE THE JUNIOR SUBORDINATED DEBENTURES, THERE MAY BE AN ADVERSE
         EFFECT ON THE TRADING MARKET AND TRADING PRICE OF YOUR INVESTMENT, AND
         THERE MAY BE ADVERSE TAX EFFECTS.

         Your investment in the capital securities may decrease in value if the
junior subordinated debentures are distributed to you in liquidation of the
Trust. We cannot predict the liquidity of the market price or market prices for
the junior subordinated debentures that may be distributed. Accordingly, the
junior subordinated debentures that you receive upon a distribution, or the
capital securities you hold pending such distribution, may trade at a discount
to the price that you paid to purchase the capital securities.

         Because you may receive the junior subordinated debentures, you must
also make an investment decision with regard to the junior subordinated
debentures. You should carefully review all of the information regarding the
junior subordinated debentures contained in this prospectus. Under "Certain
Federal Income Tax Consequences - Receipt of Junior Subordinated Debentures or
Cash Upon Liquidation of the Trust," we discuss applicable federal income tax
consequences of a distribution of the junior subordinated debentures.

YOU WILL HAVE LIMITED VOTING RIGHTS.

         As a holder of capital securities, you will have limited voting rights.
You can vote only to modify the capital securities or on the removal of the
property and Delaware trustees of the Trust upon a limited number of events. We,
along with the property trustee and the administrative trustees, may amend the
trust agreement without your consent even if these actions adversely affect your
interests, to ensure that the Trust:

         -        will not be classified as an association taxable as a
                  corporation for U.S. federal income tax purposes; and

         -        will not be required to register as an "investment company"
                  under the Investment Company Act of 1940.

         You will not have any voting rights regarding the administrative
trustees or any matters submitted to a vote of our stockholders. See
"Description of Capital Securities - Voting Rights; Amendment of the Trust
Agreement" and "-Removal of Trustees" for more information on your limited
voting rights.

THE LIMITED COVENANTS RELATING TO THE CAPITAL SECURITIES AND THE JUNIOR
         SUBORDINATED DEBENTURES DO NOT PROTECT YOU.

         The covenants in the governing documents relating to the capital
securities and the junior subordinated debentures are limited. As a result, the
governing documents do not protect you in the event of an adverse change in our
financial condition or results of operations. In addition, the governing
documents do not limit our ability, or the ability of our subsidiaries, to incur
additional debt. You should not consider the terms of the governing documents to
be a significant factor in evaluating whether we will be able to comply with our
obligations under the junior subordinated debentures or the guarantee.

TRADING CHARACTERISTICS OF THE CAPITAL SECURITIES MAY CREATE ADVERSE TAX
CONSEQUENCES FOR YOU.

         The capital securities may trade at a price that does not reflect the
value of the accrued but unpaid interest on the underlying junior subordinated
debentures. If you dispose of your capital securities between the record date
for payments on the capital securities, you may have adverse tax consequences.
Under these circumstances, you will be required to include accrued but unpaid
interest on the junior subordinated debentures allocable to the capital
securities through the date of disposition in your income. If interest on the
junior subordinated debentures is included in income under the original issue
discount provisions, you would add this amount to your adjusted tax basis in
your share of the underlying junior subordinated debentures deemed disposed. If
your selling price is less than your adjusted tax basis, which will include all
accrued but unpaid original issue discount interest included in your income, you
could recognize capital loss which cannot be applied to offset ordinary income
for federal income tax purposes, subject to exceptions. See "Certain Federal
Income Tax Consequences - Interest Income and Original Issue Discount" and " -
Sales of capital securities" for more information on possible adverse tax
consequences to you.

ABSENCE OF RATINGS AND PUBLIC MARKET; RESTRICTIONS ON RESALE.

         The capital securities have not been rated by any rating agency. There
is no existing market for the capital securities and there can be no assurance
as to:

         -        the liquidity of any markets that may develop for the capital
                  securities or the exchange capital securities; or
         -        the ability of the holders to sell the capital securities or
                  the exchange capital securities; or
         -        at what price holders of the capital securities or the
                  exchange capital securities, will be able to sell their
                  capital securities or the exchange capital securities, as the
                  case may be.

         Future trading prices of the capital securities will depend on many
  factors including, among others, prevailing interest rates, our operating
  results and the market for similar securities. The initial purchaser has
  informed the Trust and us that it intends to make a market in the capital
  securities and the exchange capital securities. However, the initial purchaser
  is not obligated to do so and any such activity may be terminated at any time
  without notice to the holders of the capital securities or the exchange
  capital securities, as applicable. In addition, such market making activity
  will be subject to the limits of the Securities Act and may be limited during
  the pendency of the exchange offer or during the period the shelf registration
  statement is required to be kept effective.

RISKS RELATING TO BANCFIRST OHIO AND FIRST NATIONAL

OUR ASSETS, SPECIFICALLY OUR SUBSIDIARY'S STOCK, COULD BE FORECLOSED UPON IF A
DEFAULT OCCURS UNDER OUR LOAN AGREEMENT.

         We have pledged 67% of all issued and outstanding capital stock of
First National as collateral under our loan agreement with a third-party lender.
At September 30, 1999, our outstanding borrowings under this loan agreement were
$6.25 million. As a bank holding company, our primary asset is the issued and
outstanding stock of First National. We do not generate operating income, but
rely on the dividends from First National. If we fail to pay principal or
interest on the loan, the lender may take the capital stock of First National
serving as collateral for the loan in satisfaction of our obligations. Any such
actions could have a material adverse effect upon our ability to receive
dividends from First National. If we do not receive dividends from First
National, we will not have the funds to pay principal and interest on the junior
subordinated debentures and the Trust will not have the funds to pay
distributions to you on the capital securities.

WE MAY NOT BE ABLE TO SUCCESSFULLY MANAGE OUR GROWTH.

         Our general strategy for growth has been to acquire banks and related
businesses that we believe are compatible with our business. We completed the
acquisition of County Savings Bank in 1996. At that time, County had total
assets approximately equal to our total assets. Since the completion of the
acquisition, we have worked to integrate County's operations and personnel with
First National. Because we did not have the systems and infrastructure in place
at the time of the acquisition to accommodate the resulting doubling of our
size, a significantly greater amount of time than initially anticipated has been
spent developing systems to accommodate the growth that resulted from this
acquisition. At present, we believe that our infrastructure is now in place to
accommodate additional growth from acquisitions. To the extent that we continue
to grow, we cannot assure you that we will be able to adequately and efficiently
manage such growth, including our ability to successfully complete the
acquisition of Milton and integrate its operations and personnel with ours.
Moreover, we may not be able to obtain regulatory approval for any acquisitions
we may want to make. Acquiring other banks and businesses will involve risks,
including:

         -        potential exposure to liabilities of banks and businesses we
                  acquire;
         -        difficulty and expense of integrating the operations and
                  personnel of banks and businesses;
         -        potential disruption of our businesses;
         -        inability to hire and train a sufficient number of skilled
                  employees;
         -        impairment of relationships with customers of the bank and
                  businesses we acquire; and
         -        incurrence of amortization expense for any acquisition
                  accounted for as a purchase.

         If we fail to manage our growth effectively, our business, financial
condition and results of operations could be materially and adversely affected.

OUR ALLOWANCE FOR LOAN LOSSES MAY NOT BE ADEQUATE TO COVER ACTUAL LOAN LOSSES.

         Increases in the allowance for loan losses could adversely affect our
results of operations. As a lender, we are exposed to the risk that our
customers will be unable to repay their loans according to their terms and that
any collateral securing the payment of their loans may not be sufficient to
cover


                                       19
<PAGE>   21

repayment. Credit losses are inherent in the lending business, particularly so
with commercial portfolio lending which comprises 49% of our total loans at
September 30, 1999.

         We make various assumptions and judgments about the collectibility of
our loan portfolio and provide an allowance for potential losses based on
various factors. If our assumptions are not accurate, our allowance for loan
losses may not be sufficient to cover our loan losses. Material increases to the
allowance for loan losses may also be necessary due to changes in economic
conditions, the performance of our loan portfolio and increases in both loan
originations and purchases. Any increase in our allowance for loan losses would
decrease our net income.

WE MAY BE UNABLE TO MANAGE INTEREST RATE RISKS AND THAT COULD REDUCE OUR NET
INTEREST INCOME.

         Our results of operations are affected principally by net interest
income which is the difference between interest earned on loans and investments
and interest expense paid on deposits and other borrowings. We cannot predict or
control changes in interest rates. Regional and local economic conditions and
the policies of regulatory authorities, including monetary policies of the Board
of Governors of the Federal Reserve System, affect interest income and interest
expense. We take measures intended to manage the risks from changes in market
interest rates. However, changes in interest rates can still have a material
adverse effect on our profitability.

         When we acquired County, we inherited interest rate swap agreements.
County had entered into these agreements to mange interest rate risk exposure.
As a result, we have managed our interest rate risk taking into consideration
the effects of these agreements. Some of the interest rate swap agreements will
begin to expire in December 1999. We do not currently intend to replace these
interest rate swap agreements as they expire. If we do not replace these
instruments, we will need to take other measures to manage our interest rate
risks. Other measures may include converting existing short-term repricing
liabilities to longer repricing terms.

         In addition, certain assets and liabilities may react in different
degrees to changes in market interest rates. For example, interest rates on some
types of assets and liabilities may fluctuate prior to changes in broader market
interest rates, while interest rates on other types may lag behind. Some of our
assets, such as adjustable rate mortgages, have features including rate caps,
which restrict changes in their interest rates.
         Interest rates are highly sensitive to many factors that are beyond our
control. Some of these factors include:

         -        inflation;
         -        recession;
         -        unemployment;
         -        money supply;
         -        international disorders; and
         -        instability in domestic and foreign financial markets.



                                       20
<PAGE>   22



Changes in interest rates may affect:

         -        the level of voluntary prepayments on our loans; and
         -        the receipt of payment in our mortgage-backed securities
                  resulting in the receipt of proceeds that may be reinvested at
                  a lower rate than the loan or mortgage-backed security being
                  prepaid.

         Although we pursue an asset-liability management strategy designed to
control our risk from changes in market interest rates, changes in interest
rates can still have a material adverse effect on our profitability.

CHANGES IN THE SBA PROGRAM OR INCREASED COMPETITION FOR SUCH LOANS COULD
ADVERSELY AFFECT OUR PROFITABILITY.

         The SBA lending program is a federal government program. The U.S.
Congress continues to scrutinize government programs, including the SBA lending
program. We cannot assure you that the SBA lending program will continue in its
present manner. Our strategic plan includes an emphasis on continued growth of
our SBA lending program. Loans generated through this program contain portions
(typically 75%) which are guaranteed by the government. We have sold these
guaranteed portions in the secondary market. The non-interest income we generate
from these sales has been an important source of revenue for us, and continues
to play a significant role in our earnings. Future non-interest income from
these activities depends on our ability to generate and sell loans under the SBA
lending program. If the U.S. Congress changes the SBA lending program, or if we
have increased competition for such loans, our operating results could be
adversely affected.

WE CANNOT PREDICT HOW CHANGES IN TECHNOLOGY WILL IMPACT OUR BUSINESS.

         The financial services industry, including the banking sector, is
increasingly affected by advances in technology, including developments in:

         -        telecommunications;
         -        data processing;
         -        automation;
         -        internet banking;
         -        telebanking; and
         -        debit cards and so-called "smart cards."

         We currently do not provide Internet banking services or "smart cards."
We are testing an Internet banking product, but we cannot assure you that we
will be able to provide this service to our customers in the foreseeable future.
Our ability to compete successfully in the future will depend on whether we can
anticipate and respond to technological changes. To develop these and other new
technologies, we will likely have to make additional capital investments.
Although we continually invest in new technology, we cannot assure you that we
will have sufficient resources or access to the necessary technology to remain
competitive in the future or that the capital investments we make will not have
an adverse material effect on our financial condition or results of operations.


                                       21
<PAGE>   23



WE ARE SUBJECT TO EXTENSIVE REGULATION.

         We will depend primarily upon dividends from First National to meet our
obligations under the junior subordinated debentures. Banking regulations may
restrict or even prevent us from receiving dividends from First National in the
future. At September 30, 1999, First National had approximately $6.2 million of
retained earnings plus net income available to pay dividends to us without
regulatory approval. However, the banking industry is heavily regulated under
both federal and state law. We cannot assure you that modifications to existing
laws or new laws will not adversely affect our business and consequently our
ability to make payments under the junior subordinated debentures.

WE HAVE BROAD DISCRETION REGARDING THE USE OF THE PROCEEDS THAT WE RECEIVED FROM
THE SALE OF THE JUNIOR SUBORDINATED DEBENTURES.

         We have allocated all of the net proceeds of our sale of junior
subordinated debentures for general corporate purposes, such as the repurchase
of our common stock and the purchase of securities by our banking subsidiary,
which may include long-term securities. Accordingly, management has broad
discretion in applying the proceeds. Pending our use of such proceeds, the funds
have been placed in short-term, interest-bearing, investment grade instruments.
Since we have not yet determined how we will use the proceeds of the offering,
you will be unable to predict the financial success of our long-term use of
proceeds. We will not receive any proceeds from this exchange offer.

                                       22


<PAGE>   24





                                 USE OF PROCEEDS

         We will not receive any proceeds from the issuance of the new
securities in this exchange offer. All of the old securities that are tendered
in the exchange offer will be retired and cancelled. All of the proceeds from
the initial sale by the Trust of its capital securities and common securities
were invested by the Trust in the junior subordinated debentures. The net
proceeds we received from the sale of the junior subordinated debentures were
approximately $19.2 million, net of commissions and other offering expenses. We
currently intend to use the net proceeds for general corporate purposes, such as
the repurchase of our common stock and the purchase of securities by our banking
subsidiary, which may include long-term securities, and we may use a portion of
the proceeds to fund the cash portion of the purchase price for the Milton
acquisition. Initially, we invested the net proceeds in short-term investment
grade financial securities.


                              ACCOUNTING TREATMENT


         The new securities to be issued in the exchange offer will be recorded
at the same carrying value as the old securities as reflected in our accounting
records on the date of the exchange. Accordingly, we will not recognize any gain
or loss for accounting purposes. The expenses of the exchange offer and the
unamortized expenses relating to the issuance of the old securities will be
amortized over the term of the old securities and the new securities to be
issued in the exchange offer.

         For financial reporting purposes, the Trust will be treated as our
subsidiary, and, accordingly, the accounts of the Trust will be included in our
consolidated financial statements. The capital securities will be included with
borrowings and presented as a separate line item in our consolidated balance
sheet under the caption "Guaranteed Preferred Beneficial Interests in
Subordinated Debt," and appropriate disclosures about the capital securities,
the guarantee and the junior subordinated debentures will be included in the
notes to consolidated financial statements. For financial reporting purposes, we
will record distributions payable on the capital securities as an interest
expense in the consolidated statements of operations.

         Future reports we file under the Exchange Act will include a footnote
to the financial statements stating that:

         -        the Trust is wholly-owned;
         -        the sole assets of the Trust are the junior subordinated
                  debentures (specifying the principal amount, interest rate and
                  maturity date of such junior subordinated debentures); and
         -        the back-up obligations, in the aggregate, constitute a full
                  and unconditional guarantee by us of the obligations of the
                  Trust under the capital securities.

         The Trust is not required to provide separate reports under the
Exchange Act.

                          PRO FORMA REGULATORY CAPITAL

         Under regulations adopted by the Federal Reserve Board, First National
is required to maintain Tier 1 capital and total capital (Tier 1 plus Tier 2
capital) equal to at least 4.0% and 8.0%, respectively, of our risk weighted
assets, and Tier 1 capital equal to at least 4.0% of our average total assets
(calculated quarterly).

         At September 30, 1999, our Tier 1 leverage capital, Tier 1 risk-based
capital and total capital amounted to $75.8 million (6.33% of average adjusted
total assets), $75.8 million (9.27% of risk weighted assets) and $82.9 million
(10.14% of risk weighted assets), respectively, exceeding all of our minimum
regulatory requirements. For additional information on the regulatory capital
requirements applicable to us, see "Regulation and Supervision."

assets having a risk weighting of 100%.

         At September 30, 1999, First National's Tier 1 leverage capital, Tier 1
risk-based capital and total capital amounted to $80.1 million (6.68% of average
adjusted total assets), $80.1 million (9.76% of risk weighted assets) and $84.1
million (10.25% of risk weighted assets), respectively, exceeding all of its
minimum regulatory requirements. For additional information on the regulatory
capital requirements applicable to First National, see "Regulation and

                              BANCFIRST OHIO CORP.
GENERAL

         We were organized as a bank holding company under the laws of the State
of Ohio. We conduct a full-service commercial and retail banking business
through our wholly-owned subsidiary, The First National Bank of Zanesville.
Effective May 16, 1998, we merged our two other banking subsidiaries, Bellbrook
Community Bank and County Savings Bank, with First National under the national
bank charter of First National. We also own a full service financial planning
company that conducts business under the name Chornyak & Associates, Inc., which
we acquired in April 1999.

         We are headquartered in Zanesville, Ohio, the county seat of Muskingum
County. Through First National, we operate 22 full-service banking facilities
which serve Muskingum, Licking, Franklin and Greene Counties, Ohio. Our primary
market extends along Interstate 70 in central Ohio and includes the markets of
Zanesville, Newark, Columbus, and Dayton. We primarily focus on providing
personalized, high quality and comprehensive banking services in order to
develop and maintain long-term relationships with our customers. We offer a
range of banking services, including:

         -        commercial and commercial real estate loans;
         -        Small Business Administration loans;
         -        residential real estate loans;
         -        consumer loans;
         -        personal and business checking accounts;
         -        savings accounts;
         -        demand and time deposits;
         -        safe deposit services; and
         -        trust, private banking, financial planning and investment
                  services.

         At September 30, 1999, on a consolidated basis, we had total assets of
$1.2 billion, total liabilities of $1.2 billion, including total deposits of
$789.3 million, total loans of $830.2 million, and total stockholders' equity of
$83.6 million.

OUR STRATEGY

         We believe our profitability in recent years is in part attributable to
the growth strategy that we began implementing in 1992. At December 31, 1991, we
had nine branch offices with assets of $298.2 million, an equity to assets ratio
of 11.82%, and operations heavily concentrated in Muskingum County. Management
believed that increased size would allow us to:

         -        take advantage of increased operating efficiencies associated
                  with the attendant economies of scale;
         -        achieve greater diversification of our markets and products;
         -        enhance shareholder value by more effectively leveraging our
                  equity capital; and
         -        more effectively position ourselves to take advantage of
                  acquisition opportunities in the rapidly changing financial
                  services industry.


                                       26
<PAGE>   28




         Given our significant market share in our primary market area, we
recognized that our desired growth would have to come primarily from expansion
into new markets. In recognition of these factors, management undertook a growth
strategy which emphasized:

         -        acquiring existing branch locations from competing
                  institutions as well as de novo branching;
         -        increasing lending to small businesses through the formation
                  of small business lending centers outside Muskingum County;
         -        acquiring bank and thrift holding companies;
         -        expanding trust, private banking and investment services; and
         -        improving technology to enhance services and manage the cost
                  of operations.

         We believe that we have been successful in implementing our strategy.
In 1992, First National acquired a $30.6 million branch of a savings and loan
association in Dresden, Ohio. Later in 1992, First National opened the first of
four small business lending centers to serve small businesses in Columbus, Ohio,
and specialize in loans guaranteed by the U.S. Department of Commerce, SBA.
During 1997 and 1998, First National was the largest originator of SBA Section
7(a) loans in Ohio and was awarded the designation of preferred lender by the
SBA. Currently, First National has small business lending centers located in
Cleveland, Columbus, Cincinnati and Dayton, Ohio, Indianapolis, Indiana,
Louisville, Kentucky and Detroit, Michigan.

Our 1995 acquisition of Bellbrook Community Bank provided access to the Dayton
metropolitan market. In August 1996, we acquired County Savings Bank which had
total assets of approximately $554 million. In October 1998, First National
opened a new branch location in Washington Township, Ohio, located in the Dayton
metropolitan market. We have also opened an additional branch location in New
Albany, Ohio, a rapidly growing suburb of Columbus, Ohio. As a result of our
strategic growth strategy, our assets have increased by more than $800 million
since December 31, 1991.

Our board of directors and management intend to seek continued controlled growth
of the organization through selective acquisitions of banks and/or savings and
loan associations. The objectives of such acquisitions will be to:

         -        increase the opportunity for quality earning asset growth,
                  deposit generation and fee-based income opportunities;

         -        diversify the earning assets portfolio and core deposit base
                  through expansion into new geographic markets;

         -        improve the potential profits from our combined operations
                  through economies of scale; and

         -        enhance shareholder value.

         In furtherance of such objectives, we intend to continue our pursuit of
business combinations which fit our strategic objectives of growth,
diversification and market expansion and which provide the potential for
enhanced shareholder value. At the present time, we do not have any
understanding or agreements for any acquisition or combination.

RECENT DEVELOPMENTS

         On January 13, 2000, we entered into an agreement to acquire Milton
Federal Financial Corporation, by merging Milton into us. Under the terms of the
agreement, we will exchange .444 shares of our common stock and $6.80 for each
of the 2,099,995 outstanding shares of Milton. We will redeem Milton's
outstanding stock options for cash equal to the acquisition price per share less
the exercise price of the options prior to closing. Based on our closing price
of $20.375 on January 12, 2000, the transaction would be valued at $33.3
million. We will account for the merger as a purchase. We expect to consummate
the merger in the second quarter of 2000, pending approval by Milton's
shareholders, regulatory approval and other customary conditions of closing.
Milton has granted us an option to purchase up to 19.9% of Milton's outstanding
shares upon the occurrence of certain events.

At September 30, 1999, Milton had total assets of $256.7 million, deposits of
$168.5 million and shareholders' equity of $25.0 million. For the twelve months
ended September 30, 1999, Milton reported net income of $1.6 million with a
return on assets of 0.63% and a return on shareholders' equity of 6.19%.


                           REGULATION AND SUPERVISION

         Almost all of our assets consist of our investment in First National,
our principal subsidiary. Thus, our ability to pay principal of, and interest
on, the junior subordinated debentures depends almost entirely on cash dividends
we receive from First National.

         First National may not pay dividends to us if, after paying those
dividends, it would fail to meet the required minimum levels under risk-based
capital guidelines and the minimum leverage ratio requirements. First National
must have the approval of federal bank regulators if a dividend in any year
would cause the total dividends for that year to exceed the sum of the current
year's net income plus retained earnings for the preceding two years, less
required transfers to surplus. At September 30, 1999, approximately $6.2 million
of retained earnings plus net income was available for the payment of dividends
to us without regulatory approval. Payment of dividends by a banking subsidiary
may be restricted at any time at the discretion of the appropriate regulator if
it deems the payment to constitute an unsafe and/or unsound banking practice or
necessary to maintain adequate capital.

         If we do not receive sufficient cash dividends from First National, it
is unlikely that we will have sufficient funds to make payments on the junior
subordinated debentures. See "Description of Junior Subordinated Debentures."

         Other statutes and regulations that affect us and First National are
summarized in "Item 1. Business - Regulation and Supervision" of our Annual
Report on Form 10-K for the fiscal year ended December 31, 1998 incorporated
into this prospectus by reference.

                              BFOH CAPITAL TRUST I

         The Trust is a statutory business trust created under Delaware law upon
the filing of a certificate of trust with the Delaware Secretary of State. The
Trust exists for the exclusive purposes of:

         -        issuing and selling the capital securities;
         -        using the proceeds from the sale of the capital securities to
                  acquire the junior subordinated debentures; and
         -        engaging in only those other activities necessary, advisable
                  or incidental thereto, including the exchange offer.

         The junior subordinated debentures are the sole assets of the Trust,
and, accordingly, payments under the junior subordinated debentures will be the
sole revenues of the Trust. We own all of the common securities of the Trust.
The common securities rank pari passu, and payments will be made thereon pro
rata, with the capital securities, except that upon the occurrence and
continuance of an event of default under the Trust agreement resulting from a
debenture event of default, our rights as holder of the common securities to
payments in respect of distributions and payments upon liquidation, redemption
or otherwise will be subordinated to the rights of the holders of the capital
securities. See "Description of Capital Securities -- Subordination of Common
Securities." We acquired common securities in a liquidation amount equal to at
least 3% of the total capital of the Trust. The Trust has a term of
approximately 35 years, but may dissolve earlier as provided in its Amended and
Restated Declaration of Trust, referred to in this prospectus as the trust
agreement. The Trust's business and affairs are conducted by the issuer
trustees, each of whom we appoint as holder of the common securities. The issuer
trustees for the Trust will be Wilmington Trust Company, as the property trustee
and as the Delaware trustee, and three administrative trustees who are our
officers. Wilmington Trust Company, as property trustee, acts as sole indenture
trustee under the trust agreement. Wilmington Trust Company also acts as
indenture trustee under the guarantee and the indenture. See "Description of
Guarantee" and "Description of Junior Subordinated Debentures." The holder of
the common securities of the Trust or, if an event of default under the trust
agreement has occurred and is continuing, the holders of not less than a
majority in liquidation amount of the capital securities will be entitled to
appoint, remove or replace the property trustee and/or the Delaware trustee. In
no event will the holders of the capital securities have the right to vote to
appoint, remove or replace the administrative trustees; such voting rights will
be vested exclusively in the holder of the common securities. The duties and
obligations of each issuer trustee are governed by the trust agreement. As
issuer of the junior subordinated debentures, we will pay all fees, expenses,
debts and obligations (other than the payment of principal of, and interest on,
the capital securities) related to the Trust and the offering of the capital
securities and will pay, directly or indirectly, all ongoing costs, expenses and
liabilities of the Trust. The principal executive office of the Trust is c/o
BancFirst Ohio Corp., 422 Main Street, Zanesville, Ohio 43702 and its telephone
number is (740) 452-8444.

                               THE EXCHANGE OFFER

PURPOSE OF THE EXCHANGE OFFER

         When we sold the outstanding capital securities on October 18, 1999, we
entered into a registration rights agreement with the initial purchaser of those
capital securities. Under the registration rights agreement, we have agreed to
file a registration statement regarding the exchange of the outstanding capital
securities for new capital securities which are registered under the Securities
Act. We have also agreed to use our reasonable best efforts to cause the
registration statement to become effective with the SEC, and to conduct this
exchange offer after the registration statement is declared effective. We will
use our reasonable best efforts to keep this registration statement effective at
least until the exchange offer is completed. The registration rights agreement
provides that we will be required to pay liquidated damages to the holders of
the outstanding capital securities if:

         -        the registration statement is not filed by March 16, 2000;
         -        the registration statement is not declared effective by April
                  15, 2000; or
         -        the exchange offer has not been completed within 30 business
                  days after the registration statement becomes effective.

TERMS OF THE EXCHANGE OFFER

         This prospectus and the accompanying letter of transmittal together
constitute the exchange offer. Upon the terms and subject to the conditions set
forth in this prospectus and in the letter of transmittal, we will accept for
exchange outstanding capital securities which are properly tendered on or before
the expiration date and are not withdrawn as permitted below. The expiration
date for this exchange offer is 5:00 p.m., New York City time, on [ ], 2000, or
such later date and time to which we, in our sole discretion, extend the
exchange offer.

         The form and terms of the new securities being issued in the exchange
offer are the same as the form and terms of the old securities, except that:

         -        the new securities being issued in the exchange offer will
                  have been registered under the Securities Act;
         -        the new securities being issued in the exchange offer will not
                  bear the restrictive legends restricting their transfer under
                  the Securities Act; and
         -        the new securities being issued in the exchange offer will not
                  contain the registration rights and liquidated damages
                  provisions contained in the old securities.

         Outstanding capital securities being tendered in the exchange offer
must be in denominations of the principal amount of $1,000 and integral
multiples of that amount.

         We expressly reserve the right, in our sole discretion:

         -        to extend the expiration date;
         -        to delay accepting any outstanding capital securities;
         -        if any of the conditions set forth below under "--Conditions
                  to the Exchange Offer" have not been satisfied, to terminate
                  the exchange offer and not accept any old securities for
                  exchange; or
         -        to amend the exchange offer in any manner.



                                       30
<PAGE>   32

     We will give oral or written notice of any extension, delay,
non-acceptance, termination or amendment as promptly as practicable by a public
announcement, and in the case of an extension, not

     later than 9:00 a.m., New York City time, on the next business day after
the previously scheduled expiration date.

         During an extension, all outstanding capital securities previously
tendered will remain subject to the exchange offer and may be accepted for
exchange by us. Any outstanding capital securities not accepted for exchange for
any reason will be returned without cost to the holder that tendered them as
promptly as practicable after the expiration or Termination of the exchange
offer.

HOW TO TENDER OLD SECURITIES FOR EXCHANGE

         When the holder of old securities tenders, and we accept, old
securities for exchange, a binding agreement between us and the tendering holder
is created, subject to the terms and conditions set forth in this prospectus and
the accompanying letter of transmittal. Except as set forth below, a holder of
outstanding capital securities who wishes to tender them for exchange must, on
or prior to the expiration date:

         -        transmit a properly completed and duly executed letter of
                  transmittal, including all other documents required by that
                  letter of transmittal, to Wilmington Trust Company, the
                  "exchange agent", at the address set forth below under the
                  heading "Exchange Agent"; or

         -        if capital securities are tendered pursuant to the book-entry
                  procedures set forth below, the tendering holder must transmit
                  an agent's message to the exchange agent at the address set
                  forth below under the heading "Exchange Agent."

     In addition, either:

         -        the exchange agent must receive the certificates for the
                  outstanding capital securities being tendered and the letter
                  of transmittal;

         -        the exchange agent must receive, prior to the expiration date,
                  a timely confirmation of the book-entry transfer of the
                  capital securities being tendered into the exchange agent's
                  account at DTC or an agent's message; or

         -        the holder must comply with the guaranteed delivery procedures
                  described below.

         The term "agent's message" means a message, transmitted to DTC and
received by the exchange agent and forming a part of a book-entry transfer,
which states DTC has received an express acknowledgment that the tendering
holder agrees to be bound by the letter of transmittal and that we may enforce
the letter of transmittal against that holder.

         THE METHOD OF DELIVERY OF THE OUTSTANDING CAPITAL SECURITIES, THE
LETTERS OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND
RISK OF THE HOLDERS. IF THE DELIVERY IS BY MAIL, WE RECOMMEND REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED. IN ALL CASES, YOU SHOULD ALLOW
SUFFICIENT TIME TO ASSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR CAPITAL
SECURITIES SHOULD BE SENT DIRECTLY TO US.

         Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the old securities surrendered for
exchange are tendered:

         -        by a holder of the old securities, who has not completed the
                  box entitled "Special Issuance Instructions" or "Special
                  Delivery Instructions" on the letter of transmittal; or

         -        for the account of an eligible institution.

         An "eligible institution" is a firm which is a member of a registered
national securities exchange or a member of the National Association of
Securities Dealers, Inc., or a commercial bank or trust company having an office
or correspondent in the United States.

         If signatures on a letter of transmittal or notice of withdrawal are
required to be guaranteed, the guarantor must be an eligible institution. If old
securities are registered in the name of a person other than the signer of the
letter of transmittal, the old securities surrendered for exchange must be
endorsed by, or accompanied by a written instrument or instruments of transfer
or exchange, in satisfactory form as determined by us in our sole discretion,
duly executed by the registered holder with the holder's signature guaranteed by
an eligible institution.

         We will determine all questions as to the validity, form, eligibility
and acceptance of old securities tendered for exchange in our sole discretion,
including questions as to time of receipt. Our determination will be final and
binding. We reserve the absolute right to:

         -        reject any and all tenders of any old security improperly
                  tendered;
         -        refuse to accept any old security if, in our judgment or the
                  judgment of our counsel, acceptance of the old security may be
                  deemed unlawful; and
         -        waive any defects or irregularities or conditions of the
                  exchange offer as to any particular old security either before
                  or after the expiration date, including the right to waive the
                  ineligibility of any holder who seeks to tender old securities
                  in the exchange offer.

         Our interpretation of the terms and conditions of the exchange offer as
to any particular old securities either before or after the expiration date,
including the letter of transmittal and the instructions to it, will be final
and binding on all parties. Holders must cure any defects and irregularities in
connection with tenders of old securities for exchange within such reasonable
period of time as we will determine, unless we waive those defects or
irregularities. Neither we, the exchange agent nor any other person shall be
under any duty to give notification of any defect or irregularity with respect
to any tender of old securities for exchange, nor shall any of us incur any
liability for failure to give that notification.

         If a person or persons other than the registered holder or holders of
the old securities tendered for exchange signs the letter of transmittal, the
tendered old securities must be endorsed or accompanied by appropriate powers of
attorney, in either case signed exactly as the name or names of the registered
holder or holders that appear on the old securities being tendered.

         If trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity sign the letter of transmittal or any old securities or any power of
attorney, those persons should so indicate when signing, and you must submit
proper evidence satisfactory to us of, such person's authority to so act unless
we waive this requirement.

         By tendering, each holder will represent to us that, among other
things, the person acquiring new securities in the exchange offer is obtaining
them in the ordinary course of its business, whether or not such person is the
holder, and that neither the holder nor such other person has any arrangement or
understanding with any person to participate in the distribution of the new
securities issued in the exchange offer. If any holder or any such other person
is an "affiliate," as defined under Rule 405 of the Securities Act, of BancFirst
Ohio, or is engaged in or intends to engage in or has an arrangement or
understanding with any person to participate in a distribution of new securities
to be acquired in the exchange offer, that holder or any such other person:


                                       32
<PAGE>   34




         -        may not rely on the applicable interpretations of the staff of
                  the SEC; and
         -        must comply with the registration and prospectus delivery
                  requirements of the Securities Act in connection with any
                  resale transaction.

         Each broker-dealer who acquired its old securities as a result of
market-making activities or other trading activities and thereafter receives new
securities issued for its own account in the exchange offer, must acknowledge
that it will deliver a prospectus in connection with any resale of such new
securities issued in the exchange offer. The letter of transmittal states that
by so acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act. See "Plan of Distribution" for a discussion of the exchange and resale
obligations of broker-dealers in connection with the exchange offer.

ACCEPTANCE OF OLD SECURITIES FOR EXCHANGE; DELIVERY OF NEW SECURITIES ISSUED IN
THE EXCHANGE OFFER

         Upon satisfaction or waiver of all of the conditions to the exchange
offer, we will accept, promptly after the expiration date, all outstanding old
securities properly tendered and will issue new securities registered under the
Securities Act. For purposes of the exchange offer, we will be deemed to have
accepted properly tendered outstanding old securities for exchange when, as and
if we have given oral or written notice to the exchange agent, with written
confirmation of any oral notice to be given promptly thereafter. See
"--Conditions to the Exchange Offer" for a discussion of the conditions that
must be satisfied before we accept any old securities for exchange.

         For each outstanding old security accepted for exchange, the holder
will receive a new security registered under the Securities Act having a
liquidation amount equal to that of the surrendered old security. Accordingly,
registered holders of new securities issued in the exchange offer on the
relevant record date for the first distribution date following the completion of
the exchange offer will receive a distribution accruing from the most recent
date to which a distribution has been paid or, if no distribution has been paid
on the outstanding capital securities, from October 18, 1999. Outstanding old
securities that we accept for exchange will cease to accrue distributions from
and after the date of completion of the exchange offer. Under the registration
rights agreement, we may be required to make additional payments in the form of
liquidated damages to the holders of the outstanding capital securities under
circumstances relating to the timing of the exchange offer.

         In all cases, we will issue new securities in the exchange offer for
outstanding old securities that are accepted for exchange only after the
exchange agent timely receives:

         -        certificates for such old securities or a timely book-entry
                  confirmation of such old securities into the exchange agent's
                  account at DTC;
         -        a properly completed and duly executed letter of transmittal
                  or an agent's message; and
         -        all other required documents.

         If for any reason set forth in the terms and conditions of the exchange
offer we do not accept any tendered outstanding old securities, or if a holder
submits outstanding old securities for a greater liquidation amount than the
holder desires to exchange, we will return such unaccepted or non-exchanged old
securities without cost to the tendering holder. In the case of old securities
tendered by book-entry transfer into the exchange agent's account at DTC, such
non-exchanged old securities will be credited to an account maintained with DTC.
We will return the old securities or have them credited to the DTC account as
promptly as practicable after the expiration or termination of the exchange
offer.

BOOK-ENTRY TRANSFERS

         The exchange agent will make a request to establish an account with
respect to the outstanding old securities at DTC for purposes of the exchange
offer as soon as practicable after the date of this prospectus. Any financial
institution that is a participant in DTC's systems must make book-entry delivery
of outstanding old securities by causing DTC to transfer such outstanding old
securities into the exchange agent's account at DTC in accordance with DTC's
procedures for transfer. That participant should transmit its acceptance to DTC
on or prior to the expiration date or comply with the guaranteed delivery
procedures described below. DTC will verify that acceptance, execute a
book-entry transfer of the tendered old securities into the exchange agent's
account at DTC and then send to the exchange agent confirmation of that
book-entry transfer. The confirmation of the book-entry transfer will include an
agent's message confirming that DTC has received an express acknowledgment from
the participant that the participant has received and agrees to be bound by the
letter of transmittal and that we may enforce the letter of transmittal against
that participant. Delivery of new securities issued in the exchange offer may be
effected through book-entry transfer at DTC. However, the letter of transmittal
or a facsimile of it or an agent's message, with any required signature
guarantees and any other required documents, must:

         -        be transmitted to and received by the exchange agent at the
                  address set forth below under "-- Exchange Agent" on or prior
                  to the expiration date; or
         -        comply with the guaranteed delivery procedures described
                  below.

GUARANTEED DELIVERY PROCEDURES

         If a holder of outstanding old securities desires to tender them but
they are not immediately available, or if the holder cannot deliver the old
securities or other required documents to the exchange agent before the
expiration date, or the procedure for book-entry transfer cannot be completed on
a timely basis, a tender may be effected if:

         -        the holder tenders the outstanding old securities through an
                  eligible institution;
         -        prior to the expiration date, the exchange agent receives from
                  that eligible institution a properly completed and duly
                  executed notice of guaranteed delivery, substantially in the
                  form we have provided, by telegram, telex, facsimile
                  transmission, mail or hand delivery, setting forth the name
                  and address of the holder of the old securities being tendered
                  and the amount of the old securities being tendered. The
                  notice of guaranteed delivery must state that the tender is
                  being made and guarantee that within three New York Stock
                  Exchange trading days after the date of execution of the
                  notice of guaranteed delivery, the certificates for all
                  physically tendered old securities, in proper form for
                  transfer, or a book-entry confirmation, as the case may be,
                  together with a properly completed and duly executed letter of
                  transmittal or agent's message with any required signature
                  guarantees and any other documents required by the letter of
                  transmittal will be deposited by the eligible institution with
                  the Exchange Agent; and
         -        the exchange agent receives the certificates for all
                  physically tendered old securities, in proper form for
                  transfer, or a book-entry confirmation, as the case may be,
                  together with a properly completed and duly executed letter of
                  transmittal or agent's message with any required signature
                  guarantees and any other documents required by the letter of
                  transmittal, within three New York Stock Exchange trading days
                  after the date of execution of the notice of guaranteed
                  delivery.

WITHDRAWAL RIGHTS

         You may withdraw tenders of your old securities at any time prior to
5:00 p.m., New York City time, on the expiration date.

         For a withdrawal to be effective, you must send a written notice of
withdrawal or a properly transmitted agent's message to the exchange agent at
one of the addresses set forth below under "-- Exchange Agent." The notice of
withdrawal must:

         -        specify the name of the person having tendered the old
                  securities to be withdrawn;

         -        identify the old securities to be withdrawn, including the
                  liquidation amount of the old securities; and

         -        where certificates for old securities are transmitted, specify
                  the name in which the old securities are registered, if
                  different from that of the withdrawing holder.

         If certificates for old securities have been delivered or otherwise
identified to the exchange agent, then, prior to the release of such
certificates, the withdrawing holder must also submit the serial numbers of the
particular certificates to be withdrawn and signed notice of withdrawal with
signatures guaranteed by an eligible institution unless the holder is an
eligible institution. If old securities have been tendered pursuant to the
procedure for book-entry transfer described above, any notice of withdrawal must
specify the name and number of the account at DTC to be credited with the
withdrawn old securities and otherwise comply with the procedures of that
facility. We will determine all questions as to the validity, form and
eligibility of such notices, including questions as to time of receipt, and our
determination will be final and binding on all parties. Any tendered old
securities so withdrawn will be deemed not to have been validly tendered for
exchange for purposes of the exchange offer. Any old securities which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the tendering holder without cost to that holder. In the case of old
securities tendered by book-entry transfer into the exchange agent's account at
DTC, the old securities withdrawn will be credited to an account maintained with
DTC for the outstanding old securities. The old securities will be returned or
credited to the DTC account as soon as practicable after withdrawal, rejection
of tender or termination of the exchange offer. Properly withdrawn old
securities may be re-tendered by following the procedures described under "--
How to Tender Old Securities for Exchange" above at any time on or prior to 5:00
p.m., New York City time, on the expiration date.

CONDITIONS TO THE EXCHANGE OFFER

         We are not required to accept for exchange, or to issue new securities
in the exchange offer for, any outstanding old securities. We may terminate or
amend the exchange offer, if at any time before the acceptance of outstanding
old securities for exchange:

         -        any federal law, statute, rule or regulation is adopted or
                  enacted which, in our judgment, would reasonably be expected
                  to impair our ability to proceed with the exchange offer;
         -        any stop order is threatened or in effect with respect to the
                  registration statement of which this prospectus constitutes a
                  part or the qualification of the indenture under the Trust
                  Indenture Act of 1939; or
         -        there occurs a change in the current interpretation by staff
                  of the SEC which permits the new securities to be issued in
                  the exchange offer to be offered for resale, resold and
                  otherwise transferred by the holders of the new securities,
                  other than broker-dealers and any holder which is an
                  "affiliate" of BancFirst within the meaning of Rule 405 under
                  the Securities Act, without compliance with the registration
                  and prospectus delivery provisions of the Securities Act,
                  provided that the new securities acquired in the exchange
                  offer are acquired in the

                                       35
<PAGE>   37
                  ordinary course of that holder's business and that holder has
                  no arrangement or understanding with any person to participate
                  in the distribution of the new securities to be issued in the
                  exchange offer.

         The preceding conditions are for our sole benefit and we may assert
them regardless of the circumstances giving rise to any such condition. We may
waive the preceding conditions in whole or in part at any time and from time to
time in our sole discretion. If we do so, the exchange offer will remain open
for at least three business days following any waiver of the preceding
conditions. Our failure at any time to exercise the foregoing rights shall not
be deemed a waiver of any such right and each such right shall be deemed an
ongoing right which we may assert at any time and from time to time.

THE EXCHANGE AGENT

         Wilmington Trust Company, in its capacity as property trustee, has been
appointed as our exchange agent for the exchange offer. All executed letters of
transmittal should be directed to our exchange agent at the address set forth
below. Questions and requests for assistance, requests for additional copies of
this prospectus or of the letter of transmittal and requests for notices of
guaranteed delivery should be directed to the exchange agent addressed as
follows:

         Wilmington Trust Company, as Exchange Agent

         BY FACSIMILE (for eligible institutions only):  (302) 651-8882

         DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET
FORTH ABOVE OR TRANSMISSION OF THE LETTER OF TRANSMITTAL VIA FACSIMILE OTHER
THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A VALID DELIVERY OF THE LETTER OF
TRANSMITTAL.

FEES AND EXPENSES

         We will not make any payment to brokers, dealers, or others soliciting
acceptance of the exchange offer except for reimbursement of mailing expenses.

         The estimated cash expenses to be incurred in connection with the
exchange offer will be paid by us and are estimated in the aggregate to be
approximately $_________.

TRANSFER TAXES

         Holders who tender their outstanding old securities for exchange will
not be obligated to pay any transfer taxes in connection with the exchange. If,
however, new securities issued in the exchange offer are to be delivered to, or
are to be issued in the name of, any person other than the holder of the old
securities tendered, or if a transfer tax is imposed for any reason other than
the exchange of the old securities in connection with the exchange offer, then
the holder must pay any such transfer taxes,


                                       36
<PAGE>   38

whether imposed on the registered holder or on any other person. If satisfactory
evidence of payment of, or exemption from, those taxes is not submitted with the
letter of transmittal, the amount of those transfer taxes will be billed
directly to the tendering holder.

CONSEQUENCES OF FAILURE OF EXCHANGE OUTSTANDING SECURITIES

         Holders who desire to tender their outstanding old securities in
exchange for new securities registered under the Securities Act should allow
sufficient time to ensure timely delivery. Neither the exchange agent nor
BancFirst Ohio nor the Trust is under any duty to give notification of defects
or irregularities with respect to the tenders of securities for exchange.

         Outstanding old securities that are not tendered or are tendered but
not accepted will, following the completion of the exchange offer, continue to
be subject to the provisions in the indenture regarding the transfer and
exchange of the outstanding old securities and the existing restrictions on
transfer set forth in the legend on the outstanding old securities and in the
offering memorandum dated October 13, 1999, relating to the outstanding old
securities. Except in limited circumstances with respect to specific types of
holders of outstanding old securities, we will have no further obligation to
provide for the registration under the Securities Act of such outstanding old
securities. In general, outstanding old securities, unless registered under the
Securities Act, may not be offered or sold except pursuant to an exemption from,
or in a transaction not subject to, the Securities Act and applicable state
securities laws.

         We do not currently anticipate that we will take any action to register
the outstanding old securities under the Securities Act or under any state
securities laws. Upon completion of the exchange offer, holders of the
outstanding old securities will not be entitled to any further registration
rights under the registration rights agreement, except under limited
circumstances.

         Holders of the new securities of either series issued in the exchange
offer and any outstanding old securities of that series which remain outstanding
after completion of the exchange offer will vote together as a single class for
purposes of determining whether holders of the requisite percentage of the class
have taken certain actions or exercised certain rights under the trust
agreement.

CONSEQUENCES OF EXCHANGING OUTSTANDING SECURITIES

         Based on interpretations of the staff of the SEC, as set forth in
no-action letters to third parties, we believe that the new securities issued in
the exchange offer may be offered for resale, resold or otherwise transferred by
holders of those new securities, other than by any holder which is an
"affiliate" of BancFirst Ohio within the meaning of Rule 405 under the
Securities Act. Those new securities may be offered for resale, resold or
otherwise transferred without compliance with the registration and prospectus
delivery provisions of the Securities Act, if:

         -        those new securities issued in the exchange offer are acquired
                  in the ordinary course of the holder's business; and

         -        the holder, other than a broker-dealer, has no arrangement or
                  understanding with any person to participate in the
                  distribution of the new securities to be issued in the
                  exchange offer.

         However, the SEC has not considered our exchange offer in the context
of a no-action letter and we cannot guarantee that the staff of the SEC would
make a similar determination with respect to our exchange offer as in such other
circumstances.



                                       37
<PAGE>   39




Each holder, other than a broker-dealer, must furnish a written representation,
at our request, that:

         -        it is acquiring the new securities issued in the exchange
                  offer in the ordinary course of its business;
         -        it is not engaged in, and does not intend to engage in, a
                  distribution of the new securities issued in the exchange
                  offer and has no arrangement or understanding to participate
                  in a distribution of new securities issued in the exchange
                  offer;
         -        it is not a broker-dealer that acquired old securities
                  directly from BancFirst Ohio or the Trust;
         -        it is not an affiliate of BancFirst Ohio; and
         -        it is not acting on behalf of any person who could not
                  truthfully make the foregoing representations.

         Each broker-dealer that receives new securities issued in the exchange
offer for its own account in exchange for outstanding old securities must
acknowledge that the old securities were acquired by that broker-dealer as a
result of market-making or other trading activities and that it will deliver a
prospectus in connection with any resale of those new securities issued in the
exchange offer . See "Plan of Distribution" for a discussion of the exchange and
resale obligations of broker-dealers in connection with the exchange offer.

         In addition, to comply with the state securities laws of certain
jurisdictions, the new securities issued in the exchange offer may not be
offered or sold in any state unless they have been registered or qualified for
sale in that state or an exemption from registration or qualification is
available and complied with by the holders selling the new securities. We have
agreed in the registration rights agreement that, prior to any public offering
of transfer restricted securities, we will register or qualify the transfer
restricted securities for offer or sale under the securities laws of any
jurisdiction requested by a holder, provided that we are not required to qualify
as a foreign corporation or as a dealer in securities in any jurisdiction where
we would not otherwise be required to qualify, or to take any action that would
subject us to taxation or to general service of process in any jurisdiction
where we are not then so subject to taxation or service of process. Unless a
holder requests, we currently do not intend to register or qualify the sale of
the new securities issued in the exchange offer in any state where an exemption
from registration or qualification is required and not available. "Transfer
restricted securities" means each outstanding old security until:

         -        the date on which that old security has been exchanged by a
                  person other than a broker- dealer for a new security in the
                  exchange offer;
         -        following the exchange by a broker-dealer in the exchange
                  offer of the outstanding old security for a new security
                  issued in the exchange offer, the date on which the new
                  security issued in the exchange offer is sold to a purchaser
                  who receives from that broker-dealer on or prior to the date
                  of the sale a copy of this prospectus;
         -        the date on which that old security has been effectively
                  registered under the Securities Act and disposed of in
                  accordance with a shelf registration statement that we file in
                  accordance with the registration rights agreement; or
         -        the date on which that old security is distributed to the
                  public in a transaction under Rule 144 of the Securities Act.

                        DESCRIPTION OF CAPITAL SECURITIES

         This summary describes the material provisions of the capital
securities. It is not complete and is subject to, and qualified by, the trust
agreement, including the definitions used in the trust agreement, and the Trust
Indenture Act of 1939. We have incorporated the definitions used in the trust
agreement in this prospectus. You can receive a complete copy of the form of
trust agreement by requesting a copy from BancFirst Ohio.

GENERAL

         The terms of the new capital securities are the same as the old capital
securities, except as described in this prospectus. The descriptions in this
section describe the new capital securities and the old capital securities
unless we have stated otherwise.

         The capital securities represent beneficial interests in the Trust. As
a holder of capital securities, you are entitled to a preference over the common
securities in certain circumstances with respect to distributions and amounts
payable on redemption of the capital securities or liquidation of the Trust, as
described under " -- Subordination of Common Securities." The trust agreement is
not qualified under the Trust Indenture Act of 1939, as amended, except upon
effectiveness of the exchange offer registration statement or the shelf
registration statement. By its terms, however, the trust agreement incorporates
certain provisions of the Trust Indenture Act, and, upon consummation of the
exchange offer or effectiveness of the shelf registration statement, the trust
agreement will be subject to and governed by the Trust Indenture Act.

         The capital securities are limited to $20.0 million aggregate
liquidation amount at any one time outstanding, including any exchange capital
securities that may be issued from time to time in exchange for the capital
securities, as described under "Exchange Offer; Registration Rights." The
capital securities rank equal to, and payments will be made on a pro rata basis
with, the common securities, except as described under " -- Subordination of
Common Securities." The property trustee has legal title to the junior
subordinated debentures and holds them in trust for the benefit of you and the
other holders of the capital securities. Our guarantee for the benefit of the
holders of the capital securities is a guarantee on a subordinated basis with
respect to the capital securities, but will not guarantee payment of
distributions or amounts payable on redemption or liquidation of the capital
securities when the Trust does not have funds legally available for such
payments. You should read "Description of Guarantee" for more information about
our guarantee.

DISTRIBUTIONS

         Distributions on the capital securities will be cumulative, and will
accumulate from October 18, 1999. Distributions will be made at the annual rate
of 9.875% of the stated liquidation amount, payable semi-annually in arrears on
the distribution dates, which are April 15 and October 15 of each year,
commencing April 15, 2000, to the holders of the capital securities on the
relevant record dates. The record dates will be the 1st day of the month in
which the relevant payment occurs. For a description of the circumstances under
which additional amounts may be paid on the capital securities, you should read
"Exchange Offer; Registration Rights." The amount of distributions payable for
any distribution period will be based on a 360-day year of twelve 30-day months.

  If any distribution date would otherwise fall on a day that is not a business
day, the distribution date will be postponed to the next day that is a business
day without any additional payments for the delay, unless the distribution would
fall in the next calendar year, in which case the distribution date will be the
last business day of the calendar year. A business day means any day other than
a Saturday or a Sunday, or a

                                       39

day on which banking institutions in New York, New York or Wilmington, Delaware
are authorized or required by law or executive order to remain closed.

         The Trust's revenue available for distribution to holders of the
capital securities will be limited to our payments to the Trust under our junior
subordinated debentures. For more information, please refer to "Description of
Junior Subordinated Debentures - General." If we do not make interest payments
on the junior subordinated debentures, the property trustee will not have funds
available to pay distributions on the capital securities and on the common
securities. We have irrevocably guaranteed the payment of distributions if and
to the extent that the Trust has funds legally available to pay the
distributions. You should read " -- Description of Guarantee" for more
information about the extent of our guarantee.

OPTION TO DEFER INTEREST PAYMENTS

         As long as no event of default exists, we have the right under the
indenture to elect to defer the payment of interest on the junior subordinated
debentures, at any time or from time to time, for no more that 10 consecutive
semi-annual periods with respect to each deferral period, provided that no
deferral period will end on a date other than an interest payment date, or
extend beyond October 15, 2029, the stated maturity date of the junior
subordinated debentures. If we defer payments, the Trust will defer semi-annual
distributions on the capital securities during the deferral period. During any
deferral period, distributions will continue to accrue on the capital securities
and on any accrued and unpaid distributions, compounded semi-annually from the
relevant distribution date at the applicable distribution rate, which will be
equal to the applicable interest rate on the junior subordinated debentures. The
term distributions includes any accumulated additional distributions.

         Before the end of any deferral period, we may extend the deferral
period, as long as the extension does not cause the deferral period to exceed 10
consecutive semi-annual periods, or, to end on a date other than an interest
payment date or extend beyond October 15, 2029. At the end of any deferral
period and upon the payment of all amounts then due on any interest payment
date, we may elect to begin a new deferral period, subject to the above
requirements. No interest shall be due and payable during a deferral period
until the deferral period ends. We must give the property trustee, the
administrative trustees and the debenture trustee notice of our election to
defer interest payments, or to extend a deferral period at least five business
days before the earlier of:

         -        the date the distributions on the capital securities would
                  have been payable, except for the election to begin a deferral
                  period; and
         -        the date the administrative trustees are required to give
                  notice to any securities exchange or automated quotation
                  system or to holders of the capital securities of the record
                  date or the date such distributions are payable, but in any
                  event not less than five business days prior to such record
                  date.

         There is no limitation on the number of times that we may elect to
begin a deferral period. Please refer to "Description of Junior Subordinated
Debentures -- Option to Extend Interest Payment Date" and "Certain Federal
Income Tax Consequences -- Original Issue Discount."


                                       40
<PAGE>   42



During any deferral period, we may not:

         -        declare or pay any dividends or distributions on, or redeem,
                  purchase, acquire, or make a liquidation payment with respect
                  to, any of our common stock;
         -        make any payment of principal of, or interest or premium, if
                  any, on or repay, repurchase or redeem any debt securities
                  that rank equal or junior to the junior subordinated
                  debentures; or
         -        make any guarantee payments with respect to any guarantee of
                  the debt securities of any subsidiary if such guarantee ranks
                  equal or junior to the junior subordinated debentures.

         Notwithstanding the foregoing, during a deferral period we may make the
following payments:

         -        dividends or distributions in shares of, or options, warrants
                  or rights to subscribe for or purchase shares of, our common
                  stock;
         -        any declaration of a dividend in connection with the
                  implementation of a stockholders' rights plan, or the issuance
                  of common stock under any such plan in the future, or the
                  redemption or repurchase of any such rights pursuant thereto;
         -        payments under the guarantee;
         -        as a result of a reclassification of our common stock or the
                  exchange or conversion of one class or series of our capital
                  stock for another class or series of our capital stock;
         -        the purchase of fractional interests in shares of our common
                  stock pursuant to the conversion or exchange provisions of
                  such capital stock or the security being converted or
                  exchanged; and
         -        purchases of common stock related to the issuance of common
                  stock or rights under any of our benefit plans for our
                  directors, officers or employees or any of our dividend
                  reinvestment plans.

         We do not currently intend to exercise our right to defer payments of
interest on the junior subordinated debentures. Our obligations under the
guarantee to make payments of distributions is limited to the extent that the
Trust has funds legally available to pay distributions. You should read
"Description of Guarantee" for more information about the extent of our
guarantee.

REDEMPTION

         Upon repayment on October 15, 2029 or prepayment, in whole or in part
prior to October 15, 2029, of the junior subordinated debentures (other than
following the distribution of the junior subordinated debentures to you as a
holder of the Trust's capital securities and us, as the holder of the Trust's
common securities), the property trustee will apply the proceeds from the
repayment or prepayment of the junior subordinated debentures (as long as the
property trustee has received written notice no later than 45 days before the
repayment) to redeem at the applicable redemption price (which may include a
premium) an amount of capital securities having an aggregate liquidation amount
equal to the principal amount of the junior subordinated debentures paid to the
Trust. We will give notice of any redemption between 30 to 60 days prior to the
redemption date.

         If we prepay less than all of the junior subordinated debentures on a
redemption date, then the property trustee will allocate the proceeds of the
prepayment on a pro rata basis among the capital securities and the common
securities. If a court of competent jurisdiction enters an order to dissolve the
Trust, the junior subordinated debentures will be subject to optional prepayment
in whole, but not in part, on or after October 15, 2009.


                                       41
<PAGE>   43



We will have the right to prepay the junior subordinated debentures:

         -        in whole or in part, on or after October 15, 2009; and

         -        in whole but not in part, at any time, if there are changes in
                  the bank regulatory, investment company or tax laws that would
                  adversely affect the status of the Trust, the capital
                  securities or the junior subordinated debentures.

         We may have to obtain regulatory approval, including the approval of
the Federal Reserve Board before we redeem any junior subordinated debentures.
Please refer to "Description of Subordinated Debentures -- Optional Prepayment"
and " -- Special Event Prepayment" for information on prepayment of the junior
subordinated debentures.

LIQUIDATION OF THE TRUST AND DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES

         We will have the right at any time to dissolve the Trust and, after
satisfying the liabilities owed to the Trust's creditors, as required by
applicable law, we will have the right to distribute the junior subordinated
debentures to the holders of the capital securities and to us as holder of the
common securities. Our right to dissolve the Trust is subject to our receiving:

         -        an opinion of counsel to the effect that if we distribute the
                  junior subordinated debentures, the holders of the capital
                  securities will not experience a taxable event; and
         -        any required regulatory approval.

         The Trust will automatically dissolve if:

         -        certain bankruptcy events occur, or we dissolve or liquidate;
         -        we distribute junior subordinated debentures having a
                  principal amount equal to the liquidation amount of the
                  capital securities to holders of the capital securities and
                  we, as sponsor, have given written directions to the property
                  trustee to dissolve the Trust (which direction is at our
                  option and, except as described above, wholly within our
                  discretion, as sponsor);
         -        the Trust redeems all of the capital securities as described
                  under " -- Redemption;" the Trust's term expires; or
         -        a court of competent jurisdiction enters an order for the
                  dissolution of the Trust.

         If the Trust is dissolved for any of the above reasons, except for a
redemption of all capital securities, it will be liquidated by the trustees as
quickly as the trustees determine to be possible by distributing to holders of
the capital securities, after satisfying the liabilities owed to the Trust's
creditors, as provided by applicable law, junior subordinated debentures having
a principal amount equal to the liquidation amount of the capital securities,
unless the property trustee determines that this distribution is not
practicable. If the property trustee determines that this distribution is not
practicable, the holders of the capital securities will be entitled to receive
an amount equal to the aggregate of the liquidation amount plus accumulated and
unpaid distributions on the capital securities to the date of payment (such
amount being the "liquidation distribution") out of the assets of the Trust
legally available for distribution to holders, after satisfying the liabilities
owed to the Trust's creditors as provided by applicable law. If the liquidation
distribution can be paid only in part because the Trust has insufficient assets
legally available to pay the full amount of the liquidation distribution, or if
a debenture event of default exists, the capital securities will have a priority
over the common securities. For more information, please refer to " --
Subordination of Common Securities."



                                       42
<PAGE>   44

         After the liquidation date is fixed for any distribution of junior
subordinated debentures to holders of the capital securities:

         -        the capital securities will no longer be deemed to be
                  outstanding;
         -        DTC or its nominee will receive in respect of each registered
                  global certificate representing capital securities a
                  registered global certificate representing the junior
                  subordinated debentures to be delivered upon this
                  distribution; and
         -        any certificates representing capital securities not held by
                  DTC or its nominee will be deemed to represent junior
                  subordinated debentures having a principal amount equal to the
                  liquidation amount of those capital securities, and bearing
                  accrued and unpaid interest in an amount equal to the
                  accumulated and unpaid distributions on those capital
                  securities until such certificates are presented to the
                  administrative trustees or their agent for cancellation, in
                  which case we will issue to those holders, and the debenture
                  trustee will authenticate, a certificate representing the
                  junior subordinated debentures.

         We cannot assure you of the market prices for the capital securities,
or the junior subordinated debentures that may be distributed to you in exchange
for the capital securities if a dissolution and liquidation of the Trust were to
occur. Accordingly, the capital securities that you purchased or received in the
exchange offer, or the junior subordinated debentures that you may receive upon
a dissolution and liquidation of the Trust, may trade at a discount to the price
that you paid to purchase the capital securities offered by this prospectus.

If we elect not to prepay the junior subordinated debentures prior to maturity
and either elect not to or we are unable to liquidate the Trust and distribute
the junior subordinated debentures to holders of the capital securities, the
capital securities will remain outstanding until the repayment of the junior
subordinated debentures on October 15, 2029.

REDEMPTION PROCEDURES

         If we redeem the junior subordinated debentures, the Trust will redeem
capital securities at the applicable redemption price with the proceeds that it
receives from our redemption of the junior subordinated debentures. Any
redemption of capital securities will be made and the applicable redemption
price will be payable on the redemption date only to the extent that the Trust
has funds legally available to pay the applicable redemption price. For more
information, you should refer to " -- Subordination of Common Securities."

         If the Trust gives a notice of redemption for the capital securities,
then, by 12:00 noon, New York City time, on the redemption date, to the extent
funds legally are available, with respect to:

         -        the capital securities held by DTC or its nominees, the
                  property trustee will deposit, or cause the paying agent to
                  deposit, irrevocably with DTC funds sufficient to pay the
                  applicable redemption price. For more information, you should
                  refer to " - Form, Denomination, Book--Entry Procedures and
                  Transfers."
         -        the capital securities held in certificated form, the property
                  trustee will irrevocably deposit with the paying agent funds
                  sufficient to pay the applicable redemption price and will
                  give the paying agent irrevocable instructions and authority
                  to pay the applicable redemption price to the holders upon
                  surrender of their certificates evidencing the capital
                  securities. For more information, you should refer to " --
                  Payment and Paying Agency."

         The paying agent will initially be the property trustee and any
co-paying agent chosen by the property trustee and acceptable to the
administrative trustees and us.



                                       43
<PAGE>   45

         Notwithstanding the foregoing, distributions payable on or before the
redemption date will be payable to the holders of the capital securities on the
relevant record dates for the related distribution dates. If the Trust gives a
notice of redemption and funds are deposited as required, then upon the date of
the deposit, all rights of the holders of the capital securities called for
redemption will cease, except the right of the holders of the capital securities
to receive the applicable redemption price, without interest, and the capital
securities called to be redeemed will cease to be outstanding.

         If any redemption date for the capital securities is not a business
day, then the applicable redemption price, without interest or any other payment
in respect of the delay, will be paid on the next business day, except that, if
the next business day falls in the next calendar year, the payment shall be made
on the last business day of the calendar year. If payment of the applicable
redemption price is improperly withheld or refused and not paid either by the
Trust or by us pursuant to the guarantee:

         -        distributions on the capital securities will continue to
                  accumulate at the rate of 9.875% per year, from the redemption
                  date originally established by the Trust to the date such
                  applicable redemption price is actually paid; and
         -        the actual payment date will be the redemption date for
                  purposes of calculating the applicable redemption price.

         Notice of any redemption will be mailed between 30 and 60 days before
the redemption date to each holder of capital securities at its registered
address. Unless we default in payment of the applicable redemption price on, or
in the repayment of, the junior subordinated debentures, on and after the
redemption date, distributions will cease to accrue on the capital securities
called for redemption.

         Subject to applicable law, including, without limitation, U.S. federal
securities laws, we or our subsidiaries may at any time, and from time to time,
purchase outstanding capital securities in the open market or by private
agreement.

SUBORDINATION OF COMMON SECURITIES

         Payment of distributions on, and the redemption price of, the capital
securities and the common securities, as applicable, will generally be made on a
pro rata basis. However, if a debenture event of default exists on any
distribution or redemption date, no payment of any distribution on, or
applicable redemption price of, any of the common securities, and no other
payment on account of the redemption, liquidation or other acquisition of the
common securities, will be made unless payment in full in cash of all
accumulated and unpaid distributions on all of the outstanding capital
securities for all distribution periods terminating on or before the
distribution or redemption date, or payment of the applicable redemption price
is made in full. All funds available to the property trustee will first be
applied to the payment in full in cash of all distributions on, or redemption
price of, the capital securities then due and payable.

         In the case of any event of default, we, as holder of all of the common
securities, will be deemed to have waived any right to act with respect to the
event of default until the effect of the event of default has been cured, waived
or otherwise eliminated. Until any event of default has been cured, waived or
otherwise eliminated, the property trustee will act solely on behalf of the
holders of the capital securities and not on our behalf, and only the holders of
the capital securities will have the right to direct the property trustee to act
on their behalf.


                                       44
<PAGE>   46
EVENTS OF DEFAULT; NOTICE

         An event of default under the indenture constitutes an event of default
under the trust agreement. See "Description of Junior Subordinated Debentures --
Debenture Events of Default."

         The trust agreement provides that within ten (10) business days after a
responsible officer of the property trustee has actual knowledge of the
occurrence of any event of default, the property trustee will give notice of the
event of default to the holders of the capital securities, the administrative
trustees and to us, as sponsor, unless the event of default has been cured or
waived. We, as sponsor, and the administrative trustees are required to file
annually with the property trustee a certificate as to whether we and the
administrative trustees have complied with the applicable conditions and
covenants of the trust agreement.

         If a debenture event of default exists, the capital securities will
have a preference over the common securities as described under " -- Liquidation
of the Trust and Distribution of Junior Subordinated Debentures" and " --
Subordination of Common Securities." An event of default does not entitle the
holders of capital securities to accelerate the maturity date of the capital
securities.

REMOVAL OF ISSUER TRUSTEES

         Unless a debenture event of default exists, we may remove the property
trustee and the Delaware trustee at any time. If a debenture event of default
exists, the property trustee and the Delaware trustee may be removed only by the
holders of a majority in liquidation amount of the outstanding capital
securities. In no event will the holders of the capital securities have the
right to vote to appoint, remove or replace the administrative trustees, because
these voting rights are vested exclusively in us as the holder of all of the
common securities. No resignation or removal of the property trustee or the
Delaware trustee and no appointment of a successor trustee shall be effective
until the acceptance of appointment by the successor trustee in accordance with
the trust agreement.

MERGER OR CONSOLIDATION OF ISSUER TRUSTEES

         If an issuer trustee that is not a natural person is merged, converted
or consolidated into another entity, or such issuer trustee is a party to a
merger, conversion or consolidation which results in a new entity, or an entity
succeeds to all or substantially all of the corporate trust business of such
issuer trustee, the new entity shall be the successor of such issuer trustee
under the trust agreement, provided that the entity is otherwise qualified and
eligible.

MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE TRUST

         The Trust may not merge with or into, consolidate, amalgamate or be
replaced by, or convey, transfer or lease substantially all of its properties
and assets to any corporation or other entity, except as described below or as
otherwise described under " -- Liquidation of the Trust and Distribution of
Junior Subordinated Debentures." The Trust may, at our request, as sponsor, and
with the consent of the administrative trustees but without the consent of the
holders of the capital securities, merge with or into, consolidate, amalgamate
or be replaced by or convey, transfer or lease substantially all of its
properties and assets to a trust organized as such under the laws of any state;
provided, that:

         -        the successor either:

                  (a) expressly assumes all of the obligations of the Trust with
                      respect to the capital securities; or



                                       45
<PAGE>   47

                  (b) substitutes securities for the capital securities that
                      have substantially the same terms as the capital
                      securities so long as the substitute securities rank equal
                      to same as the capital securities in priority with respect
                      to distributions and payments upon liquidation, redemption
                      and otherwise;

         -        we appoint a trustee of the successor possessing the same
                  powers and duties as the property trustee with respect to the
                  junior subordinated debentures;
         -        the substitute securities are listed, or any substitute
                  securities will be listed upon notification of issuance, on
                  any national securities exchange or other organization on
                  which the capital securities are then listed or quoted, if
                  any;
         -        if the capital securities, substitute securities or junior
                  subordinated debentures are rated by any nationally recognized
                  statistical rating organization prior to such transaction, the
                  transaction does not cause any of those securities to be
                  downgraded by the rating organization;
         -        the transaction does not adversely affect the rights,
                  preferences and privileges of the holders of the capital
                  securities (including any successor securities) in any
                  material respect;
         -        the successor has a purpose substantially identical to that of
                  the Trust;
         -        prior to the transaction, we received an opinion from
                  independent counsel to the Trust experienced in such matters
                  to the effect that:
                  (a)  the transaction does not adversely affect the rights,
                       preferences and privileges of the holders of the capital
                       securities (including any successor securities) in any
                       material respect (other than any dilution of such
                       holders' interests in the new entity);

                  (b)  following the transaction, neither the Trust nor the
                       successor will be required to register as an investment
                       company under the Investment Company Act;

                  (c)  continue to be classified as a grantor trust; and

         -        we, or any permitted successor or assignee owns all of the
                  common securities of the successor and guarantees the
                  obligations of the successor under the substituted securities
                  at least to the extent provided by the guarantee and the
                  common securities guarantee.

         Notwithstanding the foregoing, the Trust may not, except with the
consent of holders of 100% in liquidation amount of the capital securities,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties and assets as an entirety or substantially as
an entirety to, any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it if the transaction would cause the
Trust or the successor not to be classified as a grantor trust.

VOTING RIGHTS; AMENDMENT OF THE TRUST AGREEMENT

         Except as provided below and under " -- Mergers, Consolidations,
Amalgamations or Replacements of the Trust" and "Description of Guarantee --
Amendments and Assignment" and as otherwise required by law and the trust
agreement, the holders of the capital securities will have no voting rights.

         We, together with the property trustee and the administrative trustees,
may amend the trust agreement from time to time, without the consent of the
holders of the capital securities:

         (1) to cure any ambiguity, correct or supplement any provisions in the
trust agreement that may be inconsistent with any other provision, or to make
any other provisions with respect to matters or questions arising under the
trust agreement, which are not inconsistent with the other provisions of the
trust agreement; or

          (2) to modify, eliminate or add to any provisions of the trust
agreement as is necessary to ensure that at all times that any capital
securities are outstanding, the Trust will not be classified as an association


                                       46
<PAGE>   48

taxable as a corporation or to enable the Trust to qualify as a grantor trust,
in each case for U.S. federal income tax purposes, or to ensure that the Trust
will not be required to register as an investment company under the Investment
Company Act;

         (3) to modify, eliminate or add any provisions of the trust agreement
as is necessary to enable us or the Trust to conduct an exchange offer in the
manner contemplated by the registration rights agreement;

provided, however, that in the case of clause (1) and (3) the amendment would
not adversely affect in any material respect the interests of the holders of the
capital securities. Any amendments of the trust agreement pursuant to the
foregoing shall become effective when notice of the amendment is given to the
holders of the capital securities.

We, together with the trustees, may amend the trust agreement:

         -        with the consent of holders representing a majority (based
                  upon liquidation amount) of the outstanding capital
                  securities; and
         -        upon receipt by the trustees of an opinion of counsel
                  experienced in such matters to the effect that the amendment
                  or the exercise of any power granted to the trustees in
                  accordance with the amendment will not affect the Trust's
                  classification as an entity that is not taxable as a
                  corporation or as being a grantor trust for U.S. federal
                  income tax purposes or the Trust's exemption from status as an
                  investment company under the Investment Company Act;

provided that, without the consent of each holder of capital securities, no
amendment may change the amount or timing of any distribution on the capital
securities or otherwise adversely affect the amount of any distribution required
to be made in respect of the capital securities as of a specified date; or
restrict the right of a holder of capital securities to sue for the enforcement
of any payment on or after the specified date.

         So long as the property trustee holds any junior subordinated
debentures, the trustees may not:

         -        direct the time, method and place of conducting any proceeding
                  for any remedy available to the debenture trustee, or execute
                  any trust or power conferred on the debenture trustee with
                  respect to the junior subordinated debentures;
         -        waive certain past defaults under the indenture;
         -        exercise any right to rescind or annul a declaration
                  accelerating the maturity of the principal of the junior
                  subordinated debentures; or
         -        consent to any amendment, modification or termination of the
                  indenture or the junior subordinated debentures, where such
                  consent shall be required,

without, in each case, obtaining the prior consent of the holders of a majority
in liquidation amount of all outstanding capital securities; provided, however,
that where a consent under the indenture would require the consent of each
holder of junior subordinated debentures affected by the amendment, modification
or termination, the property trustee will not give consent without the prior
approval of each holder of the capital securities.

         The trustees will not revoke any action previously authorized or
approved by a vote of the holders of the capital securities, except by
subsequent vote of such holders. The property trustee shall notify each holder
of capital securities of any notice of default it receives with respect to the
junior subordinated debentures. In addition to obtaining the approvals of the
holders of the capital securities, prior to taking any of the foregoing actions,
the trustees shall obtain an opinion of counsel experienced in such matters to


                                       47
<PAGE>   49

the effect that the Trust will not be classified as an association taxable as a
corporation for U.S. federal income tax purposes on account of such action.


         Any required approval of holders of capital securities may be given at
a meeting of the holders convened for the purpose of approving the matter or
pursuant to written consent. The property trustee will cause a notice of any
meeting at which holders of capital securities are entitled to vote, or of any
matter upon which action by written consent of such holders has been taken, to
be given to each holder of record of capital securities in accordance with the
trust agreement.

         No vote or consent of the holders of capital securities will be
required for the Trust to redeem and cancel the capital securities in accordance
with the trust agreement.

         Notwithstanding that holders of the capital securities are entitled to
vote or consent under any of the circumstances described above, any of the
capital securities that are owned by us, the trustees or any of our or any
trustee's affiliates, shall, for purposes of such vote or consent, be treated as
if they were not outstanding.

PAYMENT AND PAYING AGENCY

         The Trust will make payments on the capital securities that are held in
global form to DTC, which will credit the relevant accounts at DTC on the
applicable distribution dates. The Trust will make payments on the capital
securities that are not held by DTC by mailing a check to the address of the
holder entitled to the payment as the holder's address appears on the register.
The paying agent will initially be the property trustee and any co-paying agent
chosen by the property trustee and acceptable to the administrative trustees and
us. The paying agent will be permitted to resign as paying agent upon 30 days'
notice to the property trustee, the administrative trustees and us. In the event
that the property trustee is no longer the paying agent, the administrative
trustees will appoint a successor (which must be a bank or trust company
acceptable to the administrative trustees and us) to act as paying agent.

RESTRICTIONS ON TRANSFER

         The original capital securities were issued, and may be transferred,
only in blocks having a liquidation amount of not less than $100,000 (100
capital securities) and multiples of $1,000 in excess thereof. Any attempted
sale, transfer or other disposition of capital securities in a block having a
liquidation amount of less than $100,000 will be deemed to be void and of no
legal effect whatsoever. Any such purported transferee will be deemed not to be
the holder of such capital securities for any purpose, including but not limited
to the receipt of distributions on such capital securities, and such purported
transferee will be deemed to have no interest whatsoever in such capital
securities.

REGISTRAR AND TRANSFER AGENT

         The property trustee will act as registrar and transfer agent for the
capital securities.

         The Trust will register transfers of the capital securities without
charge, except for any tax or other governmental charges that may be imposed in
connection with any transfer or exchange. The Trust will not be required to have
the transfer of the capital securities registered after they have been called
for redemption.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

         Except if an event of default exists, the property trustee will
undertake to perform only the duties specifically set forth in the trust
agreement. After an event of default, the property trustee must exercise the
same degree of care and skill as a prudent person would exercise or use in the
conduct of his or her own affairs. Subject to this provision, the property
trustee is not obligated to exercise any of the powers vested in it by the trust
agreement at the request of any holder of capital securities, unless it is
offered reasonable indemnity against the costs, expenses and liabilities that it
might incur. If no event of default exists and the property trustee is required
to decide between alternative causes of action, construe ambiguous provisions in
the trust agreement or is unsure of the application of any provision of the
trust agreement, and the matter is not one on which holders of the capital
securities or the common securities are entitled under the trust agreement to
vote, then the property trustee shall take such action as directed by us and, if
not directed, shall take such action as it deems advisable and in the best
interests of the holders of the capital securities and will have no liability,
except for its own bad faith, negligence or willful misconduct.

MISCELLANEOUS

         The administrative trustees are authorized and directed to conduct the
affairs of and to operate the Trust so that:

         -        the Trust will not be deemed to be an investment company
                  required to be registered under the Investment Company Act;
         -        the Trust will be classified as a grantor trust for U.S.
                  federal income tax purposes; and
         -        the junior subordinated debentures will be treated as our
                  indebtedness for U.S. federal income tax purposes.

         We, together with the administrative trustees, are authorized to take
any action, not inconsistent with applicable law, the certificate of trust of
the Trust or the trust agreement, that we and the administrative trustees
determine in our discretion is necessary or desirable, as long as it does not
materially adversely affect the interests of the holders of the capital
securities.

         The trust agreement provides that holders of the capital securities
have no preemptive or similar rights to subscribe for any additional capital
securities and the issuance of capital securities is not subject to preemptive
rights.

         The Trust may not borrow money, issue debt, execute mortgages or pledge
any of its assets.

GOVERNING LAW

         The trust agreement and capital securities will be governed by and
construed in accordance with the laws of the State of Delaware, without regard
to conflict of law principles.

                  DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES

         This summary describes the material provisions of the junior
subordinated debentures. It is not complete and is subject to, and qualified in
its entirety by, the indenture. The indenture will not be qualified under the
Trust Indenture Act, except upon effectiveness of the exchange offer
registration statement or the shelf registration statement. However, by its
terms, the indenture will incorporate by reference certain provisions of the
Trust Indenture Act and upon consummation of the exchange offer or effectiveness
of the shelf registration statement, the indenture will be governed by and
subject to the Trust Indenture Act. We have incorporated the definitions used in
the indenture in this prospectus. You can obtain a copy of the indenture by
requesting it from BancFirst Ohio. Wilmington Trust Company will act as
debenture trustee under the indenture.

GENERAL

         The Trust has invested the proceeds from the sale of the original
capital securities in the junior subordinated debentures issued by BancFirst
Ohio. The junior subordinated debentures bear interest at the annual rate of
9.875% of the principal amount of the junior subordinated debentures, payable
semi- annually in arrears on interest payment dates of April 15 and October 15
of each year and at maturity to the person in whose name each junior
subordinated debenture is registered at the close of business on the relevant
record date. The first interest payment date for the junior subordinated
debentures will be April 15, 2000. The period beginning on October 18, 1999 and
ending on but excluding April 15, 2000 and each period beginning on and
including an interest payment date and ending on but excluding the next interest
payment date is an interest period.

         We anticipate that, until the liquidation, if any, of the Trust, each
junior subordinated debenture will be held by the property trustee in trust for
the benefit of the holders of the capital securities. The amount of interest
payable for any interest period will be computed on the basis of a 360-day year
of twelve 30-day months. In the event that any interest payment date would
otherwise fall on a day that is not a business day, the interest payment date
will be postponed to the next business day (without any interest or other
payment due to the delay), unless it would fall in the next calendar year, in
which case the interest payment date shall be the last business day of the
calendar year.

         Accrued interest that is not paid on the applicable interest payment
date will bear additional interest (to the extent permitted by law) at the rate
of 9.875% per year, compounded semi-annually from the relevant interest payment
date. The term "interest" as used in this prospectus includes semi-annual
interest payments and interest on semi-annual interest payments not paid on the
applicable interest payment date.

         Notwithstanding anything to the contrary above, if the maturity date
falls on a day that is not a business day, the payment of principal and interest
will be paid on the next business day, with the same force and effect as if made
on the maturity date, and no interest on such payments will accrue from and
after the maturity date.

         The junior subordinated debentures were issued as a series of junior
subordinated deferrable interest debentures under the indenture.

         The junior subordinated debentures will mature on October 15, 2029.

         The junior subordinated debentures rank equal to all of our other
subordinated debentures which have been or may be issued to other trusts
established by us, in each case similar to the Trust, and are



                                       50
<PAGE>   52
unsecured and rank subordinate and junior to all indebtedness for money that we
borrow to the extent and in the manner set forth in the indenture. See "--
Subordination."

         We are a bank holding company regulated by the Federal Reserve Board,
and substantially all of our operating assets are owned by First National. We
are a legal entity separate and distinct from our subsidiaries. Holders of
junior subordinated debentures should look only to us for payments on the junior
subordinated debentures. The principal sources of our income are dividends,
interest and fees from First National. We rely primarily on dividends from First
National to meet our obligations for payment of principal and interest on our
outstanding debt obligations and corporate expenses. Dividend payments from
First National are subject to regulatory limitations, generally based on current
and retained earnings, imposed by the various regulatory agencies with authority
over First National. Under the Federal Deposit Insurance Act, an insured
depositary institution such as First National is prohibited from making capital
distributions, including the payment of dividends, if, after making such
distribution, the institution would become "undercapitalized" (as such term is
used in the statute). Based on First National's current financial condition, we
do not expect that this provision will have any impact on our ability to obtain
dividends from First National. At September 30, 1999, approximately $6.2 million
of retained earnings of First National were available for dividend declaration
without prior regulatory approval. During the first nine months of 1999, First
National paid dividends of $5.0 million to us.

         Payment of dividends by First National is also subject to First
National's profitability, financial condition and capital expenditures and other
cash flow requirements. The Federal Reserve Board has stated that, as a matter
of prudent banking, a bank or bank holding company should not maintain its
existing rate of cash dividends on common stock unless:

         -        the organization's net income available to common shareholders
                  over the past year has been sufficient to fund fully the
                  dividends, and
         -        the prospective rate of earnings retention appears consistent
                  with the organization's capital needs, asset quality, and
                  overall financial condition.

We cannot assure you that First National will be able to pay dividends at past
levels, or at all, in the future.

         In addition to restrictions on the payment of dividends, First National
is subject to certain restrictions imposed by federal law on any extensions of
credit to, and certain other transactions with, us and certain other affiliates,
and on investments in stock or other securities thereof. Such restrictions
prevent us and such other affiliates from borrowing from First National unless
the loans are secured by various types of collateral. Furthermore, such secured
loans, other transactions and investments by First National are generally
limited in amount as to us and as to each of such other affiliates to 10% of the
First National's capital and surplus and as to us and all of such other
affiliates to an aggregate of 20% of the First National's capital and surplus.
As of September 30, 1999, approximately $8.4 million of credit was available to
us under this limitation, if adequate collateral would have been available to
secure such borrowings.

         Because we are a holding company, our right to participate in any
distribution of assets of any subsidiary upon such subsidiary's liquidation or
reorganization or otherwise (and thus the ability of holders of the capital
securities to benefit indirectly from such distribution), is subject to the
prior claims of creditors of that subsidiary (including depositors, in the case
of First National), except to the extent that we may be recognized as a creditor
of that subsidiary. At September 30, 1999, our subsidiaries had total
liabilities, including deposits, of $1.1 billion. Accordingly, the junior
subordinated debentures are effectively subordinated to all existing and future
liabilities of our subsidiaries (including First National's deposit liabilities)
and all liabilities of any of our future subsidiaries. The indenture does not
limit the incurrence or issuance of other secured or unsecured debt by us or any
subsidiary, including senior indebtedness. See " -- Subordination."

<PAGE>   53


FORM, REGISTRATION AND TRANSFER

         If the junior subordinated debentures are distributed to the holders of
the capital securities, the junior subordinated debentures may be represented by
one or more global certificates registered in the name of Cede & Co., as the
nominee of DTC. The depositary arrangements for such junior subordinated
debentures are expected to be substantially similar to those in effect for the
capital securities.

PAYMENT AND PAYING AGENTS

         Payment of principal of (and premium, if any) and interest on the
junior subordinated debentures will be made at the office of the debenture
trustee in Wilmington, Delaware or at the office of such paying agent or paying
agents as we may designate from time to time, except that, at our option,
payment of any interest may be made, except in the case of junior subordinated
debentures in global form:

         -        by check mailed to the address of the person or entity
                  entitled to the interest payment as such address shall appear
                  in the register for the junior subordinated debentures; or
         -        by transfer to an account maintained by the person or entity
                  entitled to the interest payment as specified in the register,
                  provided that proper transfer instructions have been received
                  by the relevant record date.

         Payment of any interest on any junior subordinated debenture will be
made to the person or entity in whose name the junior subordinated debenture is
registered at the close of business on the record date for the interest payment
date, except in the case of defaulted interest. We may at any time designate
additional paying agents or rescind the designation of any paying agent; however
we will always be required to maintain a paying agent in each place of payment
for the junior subordinated debentures.

         Any moneys deposited with the debenture trustee or any paying agent, or
then held by us, in trust for the payment of the principal of (or premium, if
any) or interest on any junior subordinated debenture and remaining unclaimed
for two years after such principal (or premium, if any) or interest has become
due and payable shall, at our request, be repaid to us and the holder of the
junior subordinated debenture shall thereafter look, as a general unsecured
creditor, only to us for payment.

OPTION TO EXTEND INTEREST PAYMENT DATE

         So long as no debenture event of default exists, we will have the right
under the indenture to defer the payment of interest on the junior subordinated
debentures, at any time and from time to time, for no more than 10 consecutive
semi-annual periods for each deferral period, provided that no deferral period
shall end on a date other than an interest payment date or extend beyond October
15, 2029. At the end of a deferral period, we must pay all interest then accrued
and unpaid (together with interest thereon at the rate of 9.875% per year,
compounded semi-annually from the relevant interest payment date, to the extent
permitted by applicable law). During a deferral period, interest will continue
to accrue, and holders of the capital securities or, if the junior subordinated
debentures have been distributed to holders of the capital securities, holders
of junior subordinated debentures, will be required to include that deferred
interest in gross income for U.S. federal income tax purposes on an accrual
method of accounting prescribed by the Code and Treasury regulation provisions
on original issue discount prior to the receipt of cash attributable to that
income. See "Certain Federal IncomeTax Consequences -- Original Issue Discount."


                                       52
<PAGE>   54


During any such deferral period, we may not:

         -        declare or pay any dividends or distributions on, or redeem,
                  purchase, acquire, or make a liquidation payment with respect
                  to, any of our capital stock;
         -        make any payment of principal of, or interest or premium, if
                  any, on or repay, repurchase or redeem any of our debt
                  securities that rank equal to or junior to the junior
                  subordinated debentures; or
         -        make any guarantee payments with respect to any guarantee by
                  us of the debt securities of any of our subsidiaries
                  (including our guarantee of the capital securities of the
                  Trust and any other guarantees) if such guarantee ranks equal
                  or junior to the junior subordinated debentures other than:
                  -        dividends or distributions in shares of, or options,
                           warrants or rights to subscribe for or purchase
                           shares of, our common stock;
                  -        any declaration of a dividend in connection with the
                           implementation of a stockholders' rights plan, or the
                           issuance of stock under any such plan in the future,
                           or the redemption or repurchase of any rights
                           pursuant thereto;
                  -        payments under the guarantee;
                  -        as a result of a reclassification of our capital
                           stock or the exchange or conversion of one class or
                           series of our capital stock for another class or
                           series of our capital stock;
                  -        the purchase of fractional interests in shares of our
                           capital stock pursuant to the conversion or exchange
                           provisions of such capital stock or the security
                           being converted or exchanged; and
                  -        purchases of our common stock related to the issuance
                           of common stock or rights under any of our benefit
                           plans for our directors, officers or employees or any
                           of our dividend reinvestment plans.

         We do not currently intend to exercise our option to defer payments of
interest on the junior subordinated debentures.

         Before the end of any deferral period, we may extend the deferral
period, as long as no event of default exists and the extension does not cause
the deferral period to exceed 10 consecutive semi-annual periods, to end on a
date other than an interest payment date or to extend beyond October 15, 2029.
At the end of any deferral period and upon the payment of all then accrued and
unpaid interest (together with interest thereon at the rate of 9.875% per year,
compounded semi-annually, to the extent permitted by applicable law), we may
elect to begin a new deferral period, subject to the requirements set forth
herein. No interest will be due and payable during a deferral period until the
deferral period ends. We must give the property trustee, the administrative
trustees and the debenture trustee notice of our election at least five business
days before the earlier of:

         -        the date the distributions on the capital securities would
                  have been payable, except for the election to begin or extend
                  such deferral period;
         -        the date the administrative trustees are required to give
                  notice to any securities exchange or automated quotation
                  system on which the capital securities are listed or quoted or
                  to holders of capital securities of the record date for such
                  distributions; or
         -        the date such distributions are payable, but at least five
                  business days prior to the record date.

         The debenture trustee will notify holders of the capital securities of
our election to begin or extend a new deferral period.

         There is no limit on the number of times that we may elect to begin a
deferral period.

OPTIONAL PREPAYMENT

         The junior subordinated debentures will be prepayable, in whole or in
part, at our option on or after October 15, 2009, subject to our receipt of any
required regulatory approval, at an optional prepayment price equal to the
percentage of the outstanding principal amount of the junior subordinated
debentures specified below, plus, in each case, accrued and unpaid interest on
the junior subordinated debentures, if any, to the date of prepayment if
redeemed during the 12-month period beginning October 15 of the years indicated
below:

SPECIAL EVENT PREPAYMENT

         If there are changes in the bank regulatory, investment company or tax
laws that adversely affect the status of the Trust, the capital securities or
the junior subordinated debentures, we may, at our option and at any time,
subject to our receipt of any required regulatory approval, prepay the junior
subordinated debentures, in whole but not in part, at any time within 90 days of
the change in the law, at the special event prepayment price. If we exercise our
option to prepay the junior subordinated debentures under these circumstances,
then the proceeds of that prepayment must be applied to redeem the capital
securities at a prepayment price equal to 100% of the principal amount of the
junior subordinated debentures so prepaid, plus, in each case, accrued and
unpaid interest on the junior subordinated debentures, if any, to the date of
prepayment. See "Description of Capital Securities -- Redemption." The special
event prepayment price will be an amount equal to the greater of:

         -        100% of the principal amount of the junior subordinated
                  debentures, or
         -        the sum, as determined by a quotation agent of the present
                  values of the remaining scheduled payments of principal and
                  interest on the junior subordinated debentures from the
                  prepayment date to the maturity date, discounted to the
                  prepayment date on a semi-annual basis (assuming a 360-day
                  year consisting of twelve 30-day months) at the adjusted
                  treasury rate,

plus, in the case of each of the above scenarios, accrued and unpaid interest
and liquidated damages, if any, to the date of prepayment.

         A change in the bank regulatory law means our receipt of an opinion of
independent bank regulatory counsel experienced in such matters to the effect
that, as a result of:

         -        any amendment to, or change (including any announced
                  prospective change) in, any laws or regulations of the United
                  States or any rules, guidelines or policies of an applicable
                  regulatory agency or authority; or
         -        any official administrative pronouncement or judicial decision
                  interpreting or applying such laws or regulations,

which amendment or change is effective or which pronouncement or decision is
announced on or after the date the capital securities are first issued, the
capital securities do not constitute, or within 90 days of the opinion will not
constitute, Tier 1 Capital (or its then equivalent if we were subject to such
capital requirement).

         A change in the investment company law means the receipt by us and the
Trust of an opinion of independent securities counsel experienced in such
matters to the effect that, as a result of:

         -        any amendment to, or change (including any announced
                  prospective change) in, any laws or regulations of the United
                  States or any rules, guidelines or policies of any applicable
                  regulatory agency or authority; or
         -        any official administrative pronouncement or judicial decision
                  interpreting or applying such laws or regulations,

which amendment or change is effective or which pronouncement or decision is
announced on or after the date the capital securities are first issued, the
Trust is, or within 90 days of the date of the opinion will be, considered an
investment company that is required to be registered under the Investment
Company Act.

         A change in tax law means the receipt by us and the Trust of an opinion
of independent tax counsel experienced in such matters to the effect that, as a
result of:

         -        any amendment to, or change (including any announced
                  prospective change) in, any laws or regulations of the United
                  States or any political subdivision or taxing authority
                  thereof or therein; or
         -        any official administrative pronouncement or judicial decision
                  interpreting or applying such laws or regulations,

which amendment or change is effective or which pronouncement or decision is
announced on or after the date the capital securities are first issued, there is
more than an insubstantial risk that:

         -        the Trust is, or will be within 90 days of the date of such
                  opinion, subject to U.S. federal income tax with respect to
                  any income received or accrued on the junior subordinated
                  debentures;
         -        interest payable by us on the junior subordinated debentures
                  is not, or within 90 days of the date of such opinion will not
                  be, deductible by us, in whole or in part, for U.S. federal
                  income tax purposes; or
         -        the Trust is, or will be within 90 days of the date of such
                  opinion, subject to more than a de minimis amount of other
                  taxes, duties or other governmental charges.

<PAGE>   57




         Adjusted treasury rate means, with respect to a prepayment date, the
         rate per annum equal to:

         -        the yield, under the heading which represents the average for
                  the immediately prior week, appearing in the most recently
                  published statistical release designed "H.15 (519)" or any
                  successor publication which is published weekly by the Federal
                  Reserve Board and which established yields on actively traded
                  United States Treasury securities adjusted to constant
                  maturity under the caption "Treasury Constant Maturities," for
                  the maturity corresponding to the remaining life, as defined
                  below (if no maturity is within three months before or three
                  months after the maturity corresponding to the remaining life,
                  yields for the two published maturities most closely
                  corresponding to the remaining life shall be determined, and
                  the adjusted treasury rate shall be interpolated or
                  extrapolated from such yields on a straight-line basis,
                  rounding to the nearest month), or

         -        if such release (or any successor release) is not published
                  during the week preceding the calculation date or does not
                  contain such yields, the rate per annum equal to the
                  semi-annual equivalent yield to maturity to the comparable
                  treasury issue, calculated using a price for the comparable
                  treasury issue (expressed as a percentage of its principal
                  amount) equal to the comparable treasury price for such
                  prepayment date,

                  plus: 299 basis points.

         Comparable treasury issue means the United States Treasury security
selected by the quotation agent (defined below) giving a maturity comparable to
the remaining life of the junior subordinated debentures that would be utilized,
at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining life. If no United States Treasury security has a maturity which is
within a period from three months before to three months after the remaining
life, the two most closely corresponding United States Treasury securities, as
selected by the quotation agent, shall be used as the comparable treasury issue,
and the adjusted treasury rate shall be interpolated or extrapolated on a
straight-line basis, rounding to the nearest month, using such securities.

         Comparable treasury price means, with respect to a prepayment date:

         -        the average of three reference treasury dealer quotations for
                  such prepayment date, after excluding the highest and lowest
                  such reference treasury dealer quotations, or
         -        if the quotation agent obtains fewer than five such reference
                  treasury dealer quotations, the average of all such
                  quotations.

         Quotation agent means the reference treasury dealer appointed by us.
Reference treasury dealer means a nationally recognized U.S. Government
securities dealer in New York, New York selected by us.

         Reference treasury dealer quotations means, with respect to each
reference treasury dealer and the prepayment date, the average, as determined by
the debenture trustee, of the bid and asked prices for the comparable treasury
issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the debenture trustee by such reference treasury dealer at 5:00 p.m.,
New York time, on the third business day preceding such prepayment date.

         Remaining life means the term of the junior subordinated debentures
from the prepayment date to the maturity date.

                                       56
<PAGE>   58

We will mail any notice of prepayment between 30 and 60 days before the
prepayment date to each holder of junior subordinated debentures to be prepaid
at its registered address. Unless we default in payment of the prepayment price,
on the prepayment date interest shall cease to accrue on the junior subordinated
debentures called for prepayment.

         If the Trust is required to pay any additional taxes, duties or other
governmental charges as a result of a change in the tax law, we will pay as
additional amounts on the junior subordinated debentures any amounts as may be
necessary in order that the amount of distributions then due and payable by the
Trust on the outstanding capital securities shall not be reduced as a result of
any additional sums, including taxes, duties or other governmental charges to
which the Trust has become subject as a result of a change in the tax law.

                           of our common stock for another class or series of
                           our common stock;
                  -        the purchase of fractional interests in shares of our
                           common stock pursuant to the conversion or exchange
                           provisions of such common stock or the security being
                           converted or exchanged; and
                  -        purchases of our common stock related to the issuance
                           of common stock or rights under any of our benefit
                           plans for its directors, officers or employees or any
                           of our dividend reinvestment plans,

         if at such time:

         -        we have actual knowledge that there is any event that is, or
                  with the giving of notice or the lapse of time, or both, would
                  be, a debenture event of default and that we have not taken
                  reasonable steps to cure;
         -        we are in default with respect to our payment of any
                  obligations under the guarantee; or
         -        we have given notice of our election to exercise our right to
                  defer interest payments on the junior subordinated debentures
                  as provided in the indenture and the deferral period, or any
                  extension of the deferral period, is continuing.



                                       57
<PAGE>   59

         So long as the capital securities remain outstanding, we also will
         covenant:

         -        to directly or indirectly maintain 100% direct or indirect
                  ownership of the common securities; provided, however, that
                  any of our permitted successors under the indenture may
                  succeed to our ownership of the common securities;
         -        to use commercially reasonable efforts to cause the Trust to
                  remain a business trust, except in connection with the
                  distribution of junior subordinated debentures to the holders
                  of capital securities in liquidation of the Trust, the
                  redemption of all of the capital securities, or certain
                  mergers, consolidations or amalgamations, each as permitted by
                  the trust agreement;
         -        to use commercially reasonable efforts to cause the Trust to
                  otherwise continue not to be classified as an association
                  taxable as a corporation and to be classified as a grantor
                  trust for U.S. federal income tax purposes;
         -        to use commercially reasonable efforts to cause each holder of
                  capital securities to be treated as owning an undivided
                  beneficial interest in the junior subordinated debentures; and
         -        to not cause, as sponsor of the Trust, or permit, as holder of
                  the common securities, the dissolution, winding-up or
                  liquidation of the Trust, except as provided in the trust
                  agreement.

MODIFICATION OF INDENTURE

         From time to time, we, together with the debenture trustee, may,
without the consent of the holders of junior subordinated debentures, amend the
indenture for specified purposes, including, among other things, curing
ambiguities, defects or inconsistencies and to enable us and the Trust to
conduct and exchange offer as contemplated by the registration rights agreement,
provided that any amendment in the indenture does not materially adversely
affect the interest of the holders of junior subordinated debentures, and
qualifying, or maintaining the qualification of, the indenture under the Trust
Indenture Act.

         The indenture permits us and the debenture trustee, with the consent of
the holders of a majority in aggregate principal amount of junior subordinated
debentures, to modify the indenture in a manner affecting the rights of the
holders of the junior subordinated debentures; provided that no modification
may, without the consent of the holders of each outstanding subordinated
debenture affected:

         -        change the stated maturity date, or reduce the principal
                  amount, of the junior subordinated debentures;
         -        reduce the amount payable on prepayment or reduce the rate or
                  extend the time of payment of interest, except pursuant to our
                  right under the indenture to defer the payment of interest.
                  Please refer to " -- Option to Extend Interest Payment Date";
         -        make the principal of, (or premium, if any) or interest on,
                  the junior subordinated debentures payable in any coin or
                  currency other than that provided in the junior subordinated
                  debentures;
         -        impair or affect the right of any holder of junior
                  subordinated debentures to institute suit for the payment
                  thereof; or
         -        reduce the percentage of the principal amount of the junior
                  subordinated debentures, the holders of which are required to
                  consent to any such modification.

DEBENTURE EVENTS OF DEFAULT

         A "debenture event of default" is:

         -        our failure for 30 days to pay any interest (including
                  compounded interest and additional sums, if any), or
                  liquidated damages, if any, on the junior subordinated
                  debentures or any other debentures when due (subject to the
                  deferral of any interest due date in the case of a deferral
                  period with respect to the junior subordinated debentures or
                  other debentures as the case may be);
         -        our failure to pay any principal or premium, if any, on the
                  junior subordinated debentures or any other debentures when
                  due whether at maturity, upon prepayment, by accelerating the
                  maturity or otherwise;
         -        our failure to observe or perform, in any material respect,
                  any other covenant contained in the indenture for 90 days
                  after written notice to us from the debenture trustee or to us
                  and the debenture trustee from the holders of at least 25% in
                  aggregate outstanding principal amount of junior subordinated
                  debentures; or
         -        certain events related to our bankruptcy, insolvency or
                  reorganization.

         The holders of a majority in aggregate outstanding principal amount of
the junior subordinated debentures have, subject to certain exceptions, the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the debenture trustee. The debenture trustee or the holders
of not less than 25% in aggregate outstanding principal amount of the junior
subordinated debentures may declare the principal due and payable immediately
upon a debenture event of default. The holders of a majority in aggregate
outstanding principal amount of the junior subordinated debentures may annul
this declaration and waive the default if the default (other than the
non-payment of the principal of the junior subordinated debentures which has
become due solely by such acceleration) has been cured and a sum sufficient to
pay all matured installments of interest and principal due otherwise than by
acceleration has been deposited with the debenture trustee.

         The holders of a majority in aggregate outstanding principal amount of
the junior subordinated debentures affected may, on behalf of the holders of all
the junior subordinated debentures, waive any past default, except a default in
the payment of principal (or premium, if any) or interest (including additional
sums and compounded interest, if any), or liquidated damages, if any, (unless
such default has been cured and a sum sufficient to pay all matured installments
of interest and principal (and premium, if any) due otherwise than by
acceleration has been deposited with the debenture trustee) or a default in
respect of a covenant or provision which under the indenture cannot be modified
or amended without the consent of the holder of each outstanding junior
subordinated debenture.

         The indenture requires that we file with the debenture trustee a
certificate annually as to the absence of defaults specified under the
indenture.

         The indenture provides that the debenture trustee may withhold notice
of a debenture event of default from the holders of the junior subordinated
debentures if the debenture trustee considers it in the interest of the holders
to do so.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF CAPITAL SECURITIES

         If a debenture event of default exists that is attributable to our
failure to pay the principal of (or premium, if any) or interest (including
compounded interest and additional sums, if any), or liquidated damages, if any,
on the junior subordinated debentures on the due date, a holder of capital
securities may institute a direct action. We may not amend the indenture to
remove this right to bring a direct action



                                       59
<PAGE>   61

         without the prior written consent of the holders of all of the capital
securities. Notwithstanding any payments that we make to a holder of capital
securities in connection with a direct action, we shall remain obligated to pay
the principal of (or premium, if any) or interest (including compounded interest
and additional sums, if any) on the junior subordinated debentures, and we shall
be subrogated to the rights of the holder of the capital securities with respect
to payments on the capital securities to the extent that we make any payments to
a holder in any direct action.

         The holders of the capital securities will not be able to exercise
directly any remedies, other than those described in the above paragraph,
available to the holders of the junior subordinated debentures, unless an event
of default exists under the trust agreement. See "Description of Capital
Securities -- Events of Default; Notice."

CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS

         The indenture provides that we will not consolidate with or merge into
any other person or convey, transfer or lease all or substantially all of our
properties to any person, and no person shall consolidate with or merge into us
or convey, transfer or lease all or substantially all of its properties to us,
unless:

         -        in case we consolidate with or merge into another person or
                  convey or transfer all or substantially all of our properties
                  to any person, the successor is organized under the laws of
                  the United States or any state or the District of Columbia,
                  and the successor expressly assumes our obligations under the
                  indenture with respect to the junior subordinated debentures;
         -        immediately after giving effect to the transaction, no
                  debenture event of default, and no event which, after notice
                  or lapse of time or both, would become a debenture event of
                  default, exists; and
         -        certain other conditions as prescribed in the indenture are
                  met.

         The general provisions of the indenture do not afford holders of the
junior subordinated debentures protection in the event of a highly leveraged or
other transaction that we may become involved in that may adversely affect
holders of the junior subordinated debentures.

SATISFACTION AND DISCHARGE

         The indenture provides that when, among other things,

         -        all junior subordinated debentures not previously delivered to
                  the debenture trustee for cancellation have become due and
                  payable or will become due and payable at maturity or called
                  for prepayment within one year, and

         -        we deposit or cause to be deposited with the debenture trustee
                  funds, in trust, for the purpose and in an amount sufficient
                  to pay and discharge the entire indebtedness on the junior
                  subordinated debentures not previously delivered to the
                  debenture trustee for cancellation, for the principal (and
                  premium, if any) and interest (including compounded interest
                  and additional sums, if any) to the date of the prepayment or
                  to October 15, 2029, as the case may be,

then the indenture will cease to be of further effect (except as to our
obligations to pay all other sums due pursuant to the indenture and to provide
the officers' certificates and opinions of counsel), and we will be deemed to
have satisfied and discharged the indenture.

SUBORDINATION

         We have promised that any of our junior subordinated debentures issued
under the indenture will be ranked junior to all of our senior indebtedness to
the extent provided in the indenture. Upon any payment or distribution of our
assets to creditors upon our liquidation, dissolution, winding up,
reorganization, assignment for the benefit of our creditors, marshaling of our
assets or any bankruptcy, insolvency, debt restructuring or similar proceedings
in connection with any insolvency or bankruptcy proceeding of us, the senior
indebtedness must be paid in full all allocable amounts (as defined below)
before the holders of the junior subordinated debentures will be entitled to
receive or retain any payment in respect thereof.

         If the maturity of junior subordinated debentures is accelerated, the
holders of all senior indebtedness outstanding at such time will first be
entitled to receive payment in full of such senior indebtedness before the
holders of junior subordinated debentures will be entitled to receive or retain
any payment in respect of the principal of (or premium, if any) or interest, if
any, on the junior subordinated debentures.

         No payments on account of principal (or premium, if any) or interest,
if any, in respect of the junior subordinated debentures may be made if there
is:

         -        a default in any payment with respect to senior indebtedness;

         -        an event of default exists with respect to any senior
                  indebtedness that accelerates the maturity of the senior
                  indebtedness;

         -        or if any judicial proceeding shall be pending with respect to
                  the default.

This restriction does not apply if the total amount outstanding for such senior
indebtedness in default is less than $100,000; provided, the default does not
relate to the indebtedness under the loan agreement we currently have
outstanding with LaSalle National Bank.

         Allocable amounts, when used with respect to any senior indebtedness,
means all amounts due or to become due on such senior indebtedness less, if
applicable, any amount which would have been paid to, and retained by, the
holders of such senior indebtedness (whether as a result of the receipt of
payments by the holders of such senior indebtedness from us or any other obligor
thereon or from any holders of, or trustee in respect of, other indebtedness
that is subordinate and junior in right of payment to such senior indebtedness
pursuant to any provision of such indebtedness for the payment over of amounts
received on account of such indebtedness to the holders of such senior
indebtedness or otherwise) but for the fact that such senior indebtedness is
subordinate or junior in right of payment to (or subject to a requirement that
amounts received on such senior indebtedness be paid over to obligees on) trade
accounts payable or accrued liabilities arising in the ordinary course of
business.

         Indebtedness for money borrowed means any obligation of or any
obligation guaranteed by us, to repay borrowed money, whether or not evidenced
by bonds, debentures, notes or other written instruments; except that
indebtedness for money borrowed does not include trade accounts payable or
accrued liabilities arising in the ordinary course of business.


                                       61
<PAGE>   63




Indebtedness ranking on a parity with the junior subordinated debentures means:

         -        indebtedness for money borrowed, whether outstanding on the
                  date the indenture is executed or created, assumed or incurred
                  after the date that the indenture is executed, to the extent
                  the indebtedness for money borrowed by its terms ranks equal
                  to and not prior to the subordinated debentures in the right
                  of payment upon the happening of our dissolution, winding-up,
                  liquidation or reorganization; and
         -        all other debt securities, and guarantees in respect of those
                  debt securities, issued to any trust other than the Trust, or
                  a trustee of the trust, partnership or other entity affiliated
                  with us, that is our financing vehicle (a "financing entity"),
                  in connection with the issuance by the financing entity of
                  equity securities or other securities guaranteed by us
                  pursuant to an instrument that ranks equal to, with or junior
                  to the guarantee. The securing of any indebtedness otherwise
                  constituting indebtedness ranking on a parity with the
                  subordinated debentures shall not be deemed to prevent such
                  indebtedness from constituting indebtedness ranking on a
                  parity with the junior subordinated debentures.

         Indebtedness ranking junior to the junior subordinated debentures means
any indebtedness for money borrowed, whether outstanding on the date the
indenture is executed or created, assumed or incurred after the date the
indenture is executed, to the extent the indebtedness for money borrowed by its
terms ranks junior to and not equal to or prior to the junior subordinated
debentures (and any other indebtedness ranking on a parity with the junior
subordinated debentures) in right of payment upon the happening of our
dissolution or winding-up or liquidation or reorganization. The securing of any
indebtedness for money borrowed otherwise constituting indebtedness ranking
junior to the junior subordinated debentures shall not be deemed to prevent the
indebtedness for money borrowed from constituting indebtedness ranking junior to
the junior subordinated debentures.

         Senior indebtedness means all indebtedness for money borrowed, whether
outstanding on the date the indenture is executed or created, assumed or
incurred after the date the indenture is executed, except indebtedness ranking
on a parity with the junior subordinated debentures or indebtedness ranking
junior to the junior subordinated debentures, and any deferrals, renewals or
extensions of the senior indebtedness.

         We are a bank holding company and almost all of our operating assets
are owned by First National. We rely primarily on dividends from First National
to meet our obligations for payment of principal and interest on our outstanding
debt obligations and corporate expenses. We are a legal entity separate and
distinct from its subsidiaries. Holders of junior subordinated debentures should
look only to us for payments on the junior subordinated debentures. There are
regulatory limitations on the payment of dividends directly or indirectly to us
from First National. See " -- General." In addition, First National is subject
to certain restrictions imposed by federal law on any extensions of credit to,
and certain other transactions with, us and certain other affiliates, and on
investments in stock or other securities thereof. Such restrictions prevent us
and such other affiliates from borrowing from First National unless the loans
are secured by various types of collateral. Further, such secured loans, other
transactions and investments by First National are generally limited in amount
as to us and as to each of such other affiliates to 10% of First National's
capital and surplus and as to us and all of such other affiliates to an
aggregate of 20% of First National's capital and surplus. Accordingly, the
junior subordinated debentures will be effectively subordinated to all existing
and future liabilities of our subsidiaries.

         Because we are a bank holding company, our right to participate in any
distribution of assets of any subsidiary upon such subsidiary's liquidation or
reorganization or otherwise (and thus the ability of holders of the capital
securities to benefit indirectly from such distribution), is subject to the
prior claims of creditors of that subsidiary (including depositors, in the case
of First National), except to the extent we may be recognized as a creditor of
that subsidiary. At September 30, 1999, our subsidiaries had total

                                       62
<PAGE>   64


liabilities, including deposits, of $1.1 billion. Accordingly, the junior
subordinated debentures are effectively subordinated to all existing and future
liabilities of our subsidiaries (including First National's deposit liabilities)
and all liabilities of any of our future subsidiaries. The indenture does not
limit the incurrence or issuance of other secured or unsecured debt of us or any
subsidiary, including senior indebtedness.

RESTRICTIONS ON TRANSFER

         The junior subordinated debentures were issued and may be transferred
only in blocks having an aggregate principal amount of not less than $100,000
(100 junior subordinated debentures) and multiples of $1,000 in excess thereof.
Any attempted transfer of junior subordinated debentures in a block having an
aggregate principal amount of less than $100,000 will be deemed to be void and
of no legal effect whatsoever. Any such purported transferee shall be deemed not
to be the holder of such junior subordinated debentures for any purpose,
including but not limited to the receipt of payments on such junior subordinated
debentures, and such purported transferee shall be deemed to have no interest
whatsoever in such junior subordinated debentures.

GOVERNING LAW

         The indenture and the junior subordinated debentures will be governed
by and construed in accordance with the laws of the State of New York, without
regard to conflict of law principles.

INFORMATION CONCERNING THE DEBENTURE TRUSTEE

         Following the exchange offer and the qualification of the indenture
under the Trust Indenture Act, the debenture trustee will have and be subject to
all the duties and responsibilities specified with respect to an indenture
trustee under the Trust Indenture Act. Subject to such provisions, the debenture
trustee is not obligated to exercise any of the powers vested in it by the
indenture at the request of any holder of junior subordinated debentures, unless
offered reasonable indemnity by the holder against the costs, expenses and
liabilities which might be incurred thereby. The debenture trustee is not
required to expend or risk its own funds or otherwise incur personal financial
liability in the performance of its duties under the indenture.

                            DESCRIPTION OF GUARANTEE

         We delivered a guarantee at the same time the original capital
securities were issued. A new guarantee will be executed and delivered in this
exchange offer The terms of the new guarantee are the same as the original
guarantee, except as described in this section. The guarantee will not be
qualified as an indenture under the Trust Indenture Act, except upon
effectiveness of the registration statement related to this exchange offer. This
summary of the material provisions of the guarantee is not complete and is
subject to, and qualified in its entirety by, the guarantee and the Trust
Indenture Act. The guarantee trustee will hold the guarantee for the benefit of
the holders of the capital securities. You can obtain a copy of the guarantee by
requesting it from BancFirst Ohio. Wilmington Trust Company will act as
guarantee trustee under the guarantee.

GENERAL


         We irrevocably agreed to pay in full on a subordinated basis, to the
extent set forth herein, the payments with respect to the capital securities to
the extent not paid by the Trust. The payments that are subject to the guarantee
are:

         -        any accumulated and unpaid distributions required to be paid
                  on the capital securities, to the extent that the Trust has
                  funds legally available at that time;
         -        the applicable redemption price with respect to the capital
                  securities called for redemption, to the extent that the Trust
                  has funds legally available at that time; and
         -        upon a voluntary or involuntary dissolution, winding-up or
                  liquidation of the Trust (other than in connection with the
                  distribution of the junior subordinated debentures to holders
                  of the capital securities or the redemption of all capital
                  securities), the lesser of (a) the liquidation distribution,
                  to the extent the Trust has funds legally available at that
                  time, and (b) the amount of assets of the Trust remaining
                  available for distribution to holders of capital securities
                  after satisfying the liabilities owed to the Trust's creditors
                  as required by applicable law.

         The guarantee ranks subordinate and junior to all senior indebtedness
to the extent provided in the guarantee. See "--Status of the Guarantee." Our
obligation to make a guarantee payment may be satisfied by our direct payment of
the required amounts to the holders of the capital securities or by causing the
Trust to pay these amounts to the holders of the capital securities.

         The guarantee is an irrevocable guarantee on a subordinated basis of
the Trust's obligations under the capital securities, but will apply only to the
extent that the Trust has funds sufficient to make these payments. If we do not
make interest payments on the junior subordinated debentures held by the Trust,
then it will not be able to pay you distributions on the capital securities and
will not have funds legally available. Please refer to the "Relationship among
the Capital Securities, the Subordinated Debentures and the Guarantee" section
of this prospectus. The guarantee does not limit us from incurring or issuing
other secured or unsecured debt, including senior indebtedness, whether under
the indenture, any other indenture that we may enter into in the future or
otherwise.

         The holders of at least a majority in aggregate liquidation amount of
the capital securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the guarantee trustee in
respect of our guarantee or to direct the exercise of any trust power conferred
upon the guarantee trustee under our guarantee. Any holder of the capital
securities may institute a legal proceeding directly against us to enforce their
rights under the guarantee without first instituting a legal proceeding against
the Trust, the guarantee trustee or any other person or entity.


                                       64
<PAGE>   66

         If we default on our obligation to pay amounts payable under the junior
subordinated debentures, theTrust will lack funds for the payment of
distributions or amounts payable on redemption of the capital securities or
otherwise, and the holders of the capital securities will not be able to rely
upon the guarantee for payment of such amounts. Instead, if a debenture event of
default exists that is attributable to our failure to pay principal of (or
premium, if any) or interest on the junior subordinated debentures on a payment
date, then any holder of capital securities may institute a direct action
against us pursuant to the terms of the indenture for enforcement of payment to
that holder of the principal of (or premium, if any) or interest on such junior
subordinated debentures having a principal amount equal to the aggregate
liquidation amount of the capital securities of that holder. In connection with
a direct action, we will have a right of set-off under the indenture to the
extent that we made any payment to the holder of capital securities in the
direct action. Except as described herein, holders of capital securities will
not be able to exercise directly any other remedy available to the holders of
the junior subordinated debentures or assert directly any other rights in
respect of the junior subordinated debentures. The trust agreement provides that
each holder of capital securities by accepting the capital securities agrees to
the provisions of the guarantee and the indenture.

         We will, through our guarantee, the trust agreement, the junior
subordinated debentures and the indenture, taken together, fully, irrevocably
and unconditionally guarantee all of the Trust's obligations under the capital
securities. No single document standing alone, or operating in conjunction with
fewer than all of the other documents, constitutes that guarantee. Only the
combined operation of these documents provides a full, irrevocable and
unconditional guarantee of the Trust's obligations under the capital securities.
You should refer to "Relationship among the Capital Securities, the Junior
Subordinated Debentures and the Guarantee" for more information about our
guarantee.

STATUS OF THE GUARANTEE

         Our guarantee constitutes an unsecured obligation and ranks subordinate
and junior to all senior indebtedness in the same manner as the junior
subordinated debentures. See "Description of Junior Subordinated Debentures --
Subordination." In addition, because we are a holding company, our right to
participate in any distribution of First National's assets upon First National's
liquidation or reorganization or otherwise is subject to the prior claims of
First National's creditors (including its depositors), except to the extent we
may be recognized as a creditor of First National. Accordingly, our obligations
under the guarantee effectively are subordinated to all existing and future
liabilities of our present and future subsidiaries (including depositors of
First National). As a result, claimants should look only to our assets for
payments under the guarantee. See "Description of Junior Subordinated Debentures
- -- General."

         Our guarantee ranks equal to all of our other guarantees with respect
to preferred beneficial interests issued by other trusts. Our guarantee of the
Trust's capital securities does not limit the amount of secured or unsecured
debt, including senior indebtedness, that we or any of our subsidiaries may
incur. We expect from time to time that we will incur additional indebtedness
and that our subsidiaries will also incur additional liabilities. Our guarantee
constitutes a guarantee of payment and not of collection, enabling the
guaranteed party to institute a legal proceeding directly against us to enforce
their rights under the guarantee without first instituting a legal proceeding
against any other person or entity. Our guarantee will be held for the benefit
of the holders of the capital securities. Our guarantee will not be discharged,
except by payment of the guarantee payments in full to the extent that the Trust
has not paid, or upon distribution of the junior subordinated debentures to, the
holders of the capital securities.


                                       65
<PAGE>   67


EVENTS OF DEFAULT

         There will be an event of default under the guarantee if we fail to
perform any of our payment or other obligations under the guarantee; except that
with respect to a default in payment of any guarantee payment, we shall have
received notice of default and shall not have cured the default within 60 days
after receipt of the notice. The holders of at least a majority in liquidation
amount of the capital securities will have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the guarantee
trustee in respect of our guarantee or to direct the exercise of any trust or
power conferred upon the guarantee trustee under our guarantee.

         Any holder of the capital securities may institute a legal proceeding
directly against us to enforce the rights of the holders of the capital
securities under the guarantee without first instituting a legal proceeding
against the Trust, the guarantee trustee or any other person or entity.

         We, as guarantor, will be required to file annually with the guarantee
trustee a certificate regarding our compliance with the applicable conditions
and covenants under our guarantee.

AMENDMENTS AND ASSIGNMENT

         Except with respect to any changes that do not materially adversely
affect the rights of holders of the capital securities (in which case no vote
will be required), the guarantee may not be amended without the prior approval
of the holders of a majority of the liquidation amount of such outstanding
capital securities. You should read "Description of Capital Securities -- Voting
Rights; Amendment of the Trust Agreement" for more information about the manner
of obtaining the holders' approval. All guarantees and agreements contained in
the guarantee agreement shall bind our successors, assigns, receivers, trustees
and representatives and shall inure to the benefit of the holders of the capital
securities then outstanding.

TERMINATION OF THE GUARANTEE

         Our guarantee will terminate and be of no further force and effect
upon:

         -        full payment of the applicable redemption price of all
                  outstanding capital securities;
         -        full payment of the liquidation amount payable upon
                  liquidation of the Trust; or
         -        distribution of junior subordinated debentures to the holders
                  of the capital securities.

         Our guarantee will continue to be effective or will be reinstated, as
the case may be, if at any time any holder of the capital securities must
restore payment of any sums paid under the capital securities or the guarantee.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

     The guarantee trustee, except if we default under the guarantee, will
undertake to perform only such duties as are specifically set forth in the
guarantee and, in case a default with respect to the guarantee has occurred,
must exercise the same degree of care and skill as a prudent person would
exercise or use in the conduct of his or her own affairs. Subject to this
provision, the guarantee trustee will not be obligated to exercise any of the
powers vested in it by the guarantee at the request of any holder of the capital
securities unless it is offered reasonable indemnity against the costs, expenses
and liabilities that it might incur.

GOVERNING LAW

         The guarantee will be governed by and construed in accordance with the
laws of the State of New York, without regard to conflict of law principles.


                 RELATIONSHIP AMONG THE CAPITAL SECURITIES, THE
                JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEE

FULL AND UNCONDITIONAL GUARANTEE

         We have irrevocably guaranteed payments of distributions and other
amounts due on the capital securities to the extent the Trust has funds legally
available to pay distributions as and to the extent set forth under "Description
of Guarantee." Taken together, our obligations under the junior subordinated
debentures, the indenture, the trust agreement and the guarantee provide, a
full, irrevocable and unconditional guarantee of the Trust's payments of
distributions and other amounts due on the capital securities. No single
document standing alone or operating in conjunction with fewer than all of the
other documents constitutes this guarantee. Only the combined operation of these
documents effectively provides a full, irrevocable and unconditional guarantee
of the Trust's obligations under the capital securities.

         If and to the extent that we do not make the required payments on the
junior subordinated debentures, the Trust will not have sufficient funds to make
its related payments, including distributions on the capital securities. Our
guarantee will not cover any payments when the Trust does not have sufficient
funds legally available to make those payments. Your remedy, as a holder of
capital securities, is to institute a direct action. Our obligations under the
guarantee are subordinate and junior to all senior indebtedness.

SUFFICIENCY OF PAYMENTS

         As long as we pay the interest and other payments when due on the
junior subordinated debentures, the Trust will have sufficient funds to cover
distributions and other payments due on the capital securities, primarily
because:

         -        the aggregate principal amount or prepayment price of the
                  junior subordinated debentures will equal the sum of the
                  liquidation amount or redemption price, as applicable, of the
                  capital securities;
         -        the interest rate and interest payment dates and other payment
                  dates on the junior subordinated debentures will match the
                  distribution rate and distribution payment dates and other
                  payment dates for the capital securities;
         -        as sponsor, we will pay for all and any costs, expenses and
                  liabilities of the Trust, except for the Trust's obligations
                  to holders of capital securities; and
         -        the trust agreement also provides that the Trust is not
                  authorized to engage in any activity that is not consistent
                  with its limited purposes.

ENFORCEMENT RIGHTS OF HOLDERS OF CAPITAL SECURITIES

         You, as holder of capital securities, may institute a legal proceeding
directly against us to enforce your rights under our guarantee without first
instituting a legal proceeding against the guarantee trustee, the Trust or any
other person or entity.


                                       67
<PAGE>   69

A default or event of default under any senior indebtedness would not constitute
a default or event of default under the trust agreement. However, if there are
payment defaults under, or accelerations of, senior indebtedness, the
subordination provisions of the indenture provide that we cannot make payments
in respect of the junior subordinated debentures until we have paid the senior
indebtedness in full or we have cured any payment default or a payment default
has been waived. Our failure to make required payments on junior subordinated
debentures would constitute an event of default under the trust agreement.

LIMITED PURPOSE OF THE TRUST

         The capital securities represent beneficial interests in the Trust, and
the Trust exists for the sole purpose of issuing and selling the capital
securities, using the proceeds from the sale of the capital securities to
acquire our junior subordinated debentures and engaging in only those other
activities necessary, advisable or incidental thereto. A principal difference
between the rights of a holder of a capital security and a holder of a junior
subordinated debenture is that a holder of a junior subordinated debenture will
be entitled to receive from us the principal amount of (and premium, if any) and
interest on junior subordinated debentures held, while a holder of capital
securities is entitled to receive distributions from the Trust (or, in certain
circumstances, from us under our guarantee) if and to the extent the Trust has
funds legally available to pay the distributions.

RIGHTS UPON DISSOLUTION

         Unless the junior subordinated debentures are distributed to holders of
the capital securities, if the Trust is voluntarily or involuntarily dissolved,
wound-up or liquidated, after satisfying the liabilities owed to the Trust's
creditors as required by applicable law, the holders of the capital securities
will be entitled to receive, out of assets held by the Trust, the liquidation
distribution in cash. See "Description of Capital Securities -- Liquidation of
the Trust and Distribution of Junior Subordinated Debentures."

         If we are voluntarily or involuntarily liquidated or bankrupted, the
property trustee, as holder of the junior subordinated debentures, would be one
of our subordinated creditors, subordinated in right of payment to all senior
indebtedness, but entitled to receive payment in full of principal (and premium,
if any) and interest, before any of our stockholders receive payments or
distributions. Since we will be the guarantor under the guarantee and will agree
to pay all costs, expenses and liabilities of the Trust (other than the Trust's
obligations to the holders of its capital securities), the positions of a holder
of capital securities and a holder of junior subordinated debentures relative to
other creditors and to our stockholders in the event of our liquidation or
bankruptcy are expected to be substantially the same.

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES


CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES

         We intend to take the position that the junior subordinated debentures
will be classified for U.S. federal income tax purposes as our indebtedness. We,
together with the Trust and the holders of the capital securities (by acceptance
of a beneficial interest in a capital security) will agree to treat the junior
subordinated debentures as our indebtedness for all U.S. federal income tax
purposes. We cannot be sure that this position will not be challenged by the IRS
or, if challenged, that the challenge will not be successful. The remainder of
this discussion assumes that the junior subordinated debentures will be
classified as our indebtedness for U.S. federal income tax purposes.

GENERAL

         In the opinion of Baker & Hostetler LLP, special federal income tax
counsel to us and the Trust, the following describes the material U.S. federal
income tax consequences of the purchase, ownership and disposition of a capital
security.

         This summary addresses only the tax consequences to a person that
acquires a capital security on its original issuance at its original price and
that holds the security as a capital asset. This summary does not address all
tax consequences that may be applicable to a beneficial owner of a capital
security and does not address the tax consequences to holders subject to special
tax regimes (like banks, thrifts, real estate investment trusts, regulated
investment companies, insurance companies, dealers in securities or currencies,
tax-exempt investors or persons that will hold a capital security as a position
in a "straddle," as part of a "synthetic security" or "hedge" or as part of a
"conversion transaction" or other integrated investment). This summary does not
include any description of any alternative minimum tax consequences or the tax
laws of any state or local government or of any foreign government that may
apply to a capital security. Except as noted below in the discussion of Non-U.S.
Holders, this discussion is addressed to a U.S. Holder, which is defined as a
beneficial owner of a capital security that, for U.S. federal income tax
purposes, is (or is treated as):

         -        a citizen or individual resident of the United States;
         -        a corporation or partnership (or entity treated for federal
                  income tax purposes as a corporation or partnership) created
                  or organized in or under the laws of the United States or any
                  political subdivision thereof;
         -        an estate the income of which is includible in gross income
                  for U.S. federal income tax purposes without regarding to its
                  source; or
         -        a trust if a court within the United States is able to
                  exercise primary supervision over the administration of the
                  trust and one or more U.S. persons have the ability to control
                  all substantial decisions of the trust.

         This summary does not address the tax consequences to any shareholder,
partner or beneficiary of a holder of a capital security. This summary is based
on the Code, Treasury regulations thereunder and the administrative and judicial
interpretations thereof, as of the date hereof, all of which are subject to
change, possibly on a retroactive basis. An opinion of Baker & Hostetler LLP is
not binding on the IRS or the courts. No rulings have been or are expected to be
sought from the IRS with respect to any of the matters described herein. We can
give no assurance that the opinions expressed herein will not be challenged by
the IRS or, if challenged, that the challenge will not be successful.

         YOU ARE ADVISED TO CONSULT WITH YOUR OWN TAX ADVISORS WITH RESPECT TO
THE TAX CONSEQUENCES TO YOU OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE
CAPITAL SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN,
AND OTHER TAX LAWS AND POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR
OTHER TAX LAWS.

CLASSIFICATION OF THE TRUST

         In connection with the original issuance of the capital securities,
Baker & Hostetler LLP rendered its opinion that, under then current law and
assuming full compliance with the terms of the trust agreement and the indenture
(and certain other documents), and based on certain facts and assumptions
contained in that opinion, the Trust will be classified for U.S. federal income
tax purposes as a grantor trust and not as an association taxable as a
corporation. Accordingly, for U.S. federal income tax purposes, the Trust will
not be subject to U.S. federal income tax, and each holder of a capital security
will be required to include in its gross income any interest (or accrued
original issue discount), with respect to its allocable share of the junior
subordinated debentures.

INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT

         Under the indenture, we have the right to defer the payment of interest
on the junior subordinated debentures at any time or from time to time for one
or more deferral periods not exceeding 10 consecutive semi-annual periods each,
provided that no deferral period shall end on a date other than an interest
payment date or extend beyond October 15, 2029. By reason of that right, the
Treasury regulations will subject the junior subordinated debentures to the
rules in the Code and Treasury regulations on debt instruments issued with
original issue discount, unless the indenture or junior subordinated debentures
contain terms or conditions that make the likelihood of exercise of the deferral
option remote. Under the Treasury regulations, a "remote" contingency that
stated interest will not be timely paid will be ignored in determining whether a
debt instrument is issued with original issue discount. Although the answer is
not clear, we believe that the likelihood that we would exercise our option to
defer payments of interest is "remote" since exercising that option would, among
other things, prevent us from declaring dividends on any class of our equity
securities. Accordingly, we intend to take the position that the junior
subordinated debentures will not be considered to be issued with original issue
discount and, accordingly, stated interest on the junior subordinated debentures
generally will be taxable to a holder as ordinary income at the time it is paid
or accrued in accordance with such holder's method of accounting.

         Under the Treasury regulations, if we were to exercise our option to
defer payments of interest, the junior subordinated debentures would at that
time be treated as issued with original issue discount, and all stated interest
on the junior subordinated debentures would thereafter be treated as original
issue discount as long as the junior subordinated debentures remain outstanding.
If this occurred, all of a holder's interest income with respect to the junior
subordinated debentures would thereafter be accounted for on an economic accrual
basis regardless of such holder's method of tax accounting, and actual
distributions of stated interest would not be reported as taxable income.
Consequently, a holder of a capital security would be required to include in
gross income original issue discount even though we would not make actual cash
payments during a deferral period. The amount of such includible original issue
discount could be significant. Also, under the Treasury regulations, if the
option to defer the payment of interest were determined not to be "remote," the
junior subordinated debentures would be treated as having been originally issued
with original issue discount. In such event, a holder would be required to
include in gross income an amount of original issue discount each taxable year
that approximates the amount of interest that accrues on the junior subordinated
debentures at the stated interest rate, regardless of such holder's method of
tax accounting, and actual cash payments of interest on the junior subordinated
debenture would not be separately includible in gross income. These Treasury



                                       70
<PAGE>   72

regulations have not yet been addressed in any rulings or other interpretations
by the IRS, and it is possible that the IRS could take a position contrary to
the interpretation described herein.

         Because income on the capital securities will constitute interest or
original issue discount, corporate holders of the capital securities will not be
entitled to a dividends-received deduction with respect to any income recognized
with respect to the capital securities.

RECEIPT OF JUNIOR SUBORDINATED DEBENTURE OR CASH UPON LIQUIDATION OF THE TRUST

         We will have the right at any time to liquidate the Trust and cause the
junior subordinated debentures to be distributed to the holders of the trust
securities. Under current law, the liquidation of the Trust and the distribution
of the junior subordinated debentures to trust security holders, for U.S.
federal income tax purposes, would be treated as a nontaxable event to each
holder, and the aggregate tax basis in the junior subordinated debentures
received by such holder would be equal to the holder's aggregate tax basis in
its capital securities surrendered. A holder's holding period in the junior
subordinated debentures received in liquidation of the Trust would be no shorter
than the period during which the capital securities were held by that holder.

         The junior subordinated debentures may be prepaid in cash, and the
proceeds of that prepayment would be distributed to holders in redemption of
their capital securities. Under current law, that redemption would constitute,
for U.S. federal income tax purposes, a taxable disposition of the redeemed
capital securities, the tax consequences of which are described below under
"--Sales or Redemptions of Capital Securities."

SALES OR REDEMPTIONS OF CAPITAL SECURITIES

         On a sale or redemption of a capital security for cash, a holder will
recognize gain or loss equal to the difference between its adjusted tax basis in
the capital security and the amount realized on the sale or redemption of that
capital security. If the rules regarding original issue discount do not apply, a
holder's adjusted basis in a capital security generally will be its initial
purchase price, and if the holder uses an accrual method of accounting, the
holder will have a basis in any accrued but unpaid interest. If the rules
regarding original issue discount apply, a holder's adjusted basis in a capital
security generally will be its initial purchase price increased by any original
issue discount previously included in the holder's gross income to the date of
disposition and decreased by any payments received on the capital security. Gain
or loss recognized on a sale or redemption of a capital security will be capital
gain or loss. Capital gain recognized by an individual in respect of a capital
security held for more than one year as of the date of sale or redemption is
subject to a maximum U.S. federal income tax rate of 20 percent.

         The capital securities may trade at a price that discounts any accrued
but unpaid interest on the junior subordinated debentures. Therefore, the amount
realized by a holder who disposes of a capital security between distribution
payment dates and whose adjusted basis in the capital security has been
increased by the amount of any accrued but unpaid original issue discount (or
interest) may be less than the holder's adjusted basis in the capital security.
A holder's basis in a capital security could be increased either under the rules
regarding original issue discount or, if those rules do not apply, in the case
of a holder that uses an accrual method of accounting, under the accrual
accounting rules. In that case, the holder will recognize a capital loss.
Subject to a limited exception in the case of individual taxpayers, capital
losses cannot be applied to offset ordinary income for U.S. federal income tax
purposes.


                                       71
<PAGE>   73

EXCHANGE OF CAPITAL SECURITIES

         The exchange of the capital securities for exchange capital securities
pursuant to the exchange offer should not be treated as an exchange for federal
income tax purposes and, therefore, should not be a taxable event to holders for
United States federal income tax purposes, because the exchange capital
securities should not be considered to differ materially in kind or extent from
the capital securities and because the exchange will occur by operation of the
terms of the capital securities. If the exchange were treated as an exchange for
United States federal income tax purposes, such exchange should constitute a
recapitalization for federal income tax purposes. Accordingly, the exchange
capital securities should have the same issue price as the capital securities,
and a holder should have the same adjusted tax basis and holding period in the
exchange capital securities as the holder had in the capital securities
immediately before the exchange.

NON-U.S. HOLDERS

         For purposes of this discussion, a "Non-U.S. Holder" generally is any
corporation, individual, partnership, estate or trust that is not a U.S. Holder
for U.S. federal income tax purposes.

         Under current U.S. federal income tax laws, subject to the discussion
below of backup withholding, payments by the Trust or any of its paying agents
to a Non-U.S. Holder will not be subject to U.S. federal withholding tax,
provided that (a) the Non-U.S. Holder does not own, actually or constructively,
ten percent or more of the total combined voting power of all classes of our
stock entitled to vote, (b) the Non-U.S. Holder is not a controlled foreign
corporation that is related to us through stock ownership, (c) the Non-U.S.
Holder is not a bank whose receipt of interest on the junior subordinated
debentures is described in Section 881(c)(3)(A) of the Code, and (d) either (A)
the Non-U.S. Holder certifies to the Trust or its agent, under penalties of
perjury, that it is not a U.S. Holder and provides its name and address or (B) a
securities clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of business (a "Financial
Institution") and holds the capital security in that capacity certifies to the
Trust or its agent, under penalties of perjury, that the statement has been
received from the Non-U.S. Holder by it or by a Financial Institution between it
and the Non-U.S. Holder and furnishes the Trust or its agent with a copy
thereof. New Treasury regulations provides alternative methods for satisfying
the certification requirements described in clause (d), effective for certain
payments made after December 31, 2000.

         If a Non-U.S. Holder is engaged in a trade or business in the United
States and interest on the capital securities (or the junior subordinated
debentures) is effectively connected with the conduct of that trade or business,
the Non-U.S. Holder, although exempt from the withholding tax discussed above,
will be subject to U.S. federal income tax on that interest on a net income
basis in generally the same manner as if it were a U.S. Holder. In addition, if
such Non-U.S. Holder is a foreign corporation, it may be subject to a branch
profits tax equal to 30% of its effectively connected earnings and profits that
are repatriated or treated as repatriated. For this purpose, the interest income
would be included in the foreign corporation's earnings and profits. In the case
of a Non-U.S. Holder entitled to the benefits of a tax treaty with the United
States, the foregoing discussion generally applies only if the Non-U.S. Holder
is engaged in business in the United States through a U.S. permanent
establishment and the income on the junior subordinated debentures is
attributable to that permanent establishment within the meaning of the treaty,
and the rate of the branch profits tax may be limited to a rate prescribed by
the treaty for the withholding of tax on dividends. New final Treasury
regulations generally prescribe new methods for certifying that a Non-U.S.
Holder is exempt from the withholding of U.S. federal income tax by reason of
being engaged in trade or business or the United States.



                                       72
<PAGE>   74

         Any gain recognized upon a sale or other disposition of capital
securities (or junior subordinated debentures) generally will not be subject to
U.S. federal income tax unless (1) the gain is, or is treated as, effectively
connected with a U.S. trade or business of the Non-U.S. Holder or (2) in the
case of a Non-U.S. Holder who is an individual, that individual is present in
the United States for 183 days or more in the taxable year of the sale or other
disposition, and certain other conditions are met.

BACKUP WITHHOLDING TAX AND INFORMATION REPORTING

         The amount of interest, including original issue discount, accrued on
capital securities held of record by U.S. persons (other than corporations and
other exempt holders) will be reported to the IRS. "Backup" withholding at a
rate of 31% will apply to payments of interest to non-exempt U.S. persons unless
the holder furnishes its taxpayer identification number in the manner prescribed
in applicable Treasury regulations, certifies that the number is correct,
certifies as to no loss of exemption from backup withholding and meets certain
other conditions.

         Payment of the proceeds from the disposition of capital securities to
or through the United States office of a broker is subject to information
reporting and backup withholding unless the holder or beneficial owner
establishes an exemption from information reporting and backup withholding.

         Non-U.S. Holders are generally exempt from the information reporting
and backup withholding rules but may be required to comply with certain
certification and identification requirements to prove their exemption.

         Any amount withheld from a holder under the backup withholding rules
will be allowed as a refund or credit against such holder's U.S. federal income
tax liability, provided the required information is furnished to the IRS.

         It is anticipated that income on capital securities will be reported to
holders on Form 1099 (or any successor form) and mailed to holders of capital
securities by January 31 following each calendar year.

         THE U.S. FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR
GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S
PARTICULAR SITUATION. YOU SHOULD CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE
TAX CONSEQUENCES TO YOU OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF A CAPITAL
SECURITY, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER
TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN U.S. FEDERAL OR OTHER TAX LAWS.

                              ERISA CONSIDERATIONS

GENERAL

         In evaluating the purchase of capital securities, a fiduciary of a
qualified profit-sharing, pension or stock bonus plan, including a plan for
self-employed individuals and their employees or any other employee benefit plan
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), a collective investment fund or separate account in which such plans
invest and any other investor using assets that are treated as assets of an
employee benefit plan subject to ERISA (each, a "Plan" and collectively,
"Plans") should consider:

         -        whether the ownership of capital securities is in accordance
                  with the documents and instruments governing such Plan;
         -        whether the ownership of capital securities is solely in the
                  interest of Plan participants and beneficiaries and otherwise
                  consistent with the fiduciary's responsibilities and in
                  compliance with the requirements of Part 4 of Title I of
                  ERISA, including, in particular, the diversification, prudence
                  and liquidity requirements of Section 404 of ERISA and the
                  prohibited transaction provisions of Section 406 of ERISA and
                  Section 4975 of the Code;
         -        whether the assets of the Trust are treated as assets of the
                  Plan; and
         -        the need to value the assets of the Plan annually.

In addition, the fiduciary of an individual retirement arrangement under 408 of
the Code (an "IRA") considering the purchase of capital securities should
consider whether the ownership of the capital securities would result in a
non-exempt prohibited transaction under Section 4975 of the Code.

         Governmental plans and certain church plans (each as defined under
ERISA) are not subject to the prohibited transaction rules. Such plans may,
however, be subject to federal, state or local laws or regulations which may
affect their investment in the capital securities. Any fiduciary of such a
governmental or church plan considering an investment in the capital securities
should determine the need for, and the availability, if necessary, of any
exemptive relief under such laws or regulations.

         The fiduciary investment considerations summarized below provide a
general discussion that does not include all of the fiduciary investment
considerations relevant to Plans and, where indicated, IRAs. This summary is
based on the current provisions of ERISA and the Code and regulations and
rulings thereunder, and may be changed (perhaps adversely and with retroactive
effect) by future legislative, administrative or judicial action.

         PLANS AND IRAS THAT ARE PROSPECTIVE PURCHASERS OF CAPITAL SECURITIES
SHOULD CONSULT WITH AND RELY UPON THEIR OWN ADVISORS IN EVALUATING THESE MATTERS
IN LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES.

PLAN ASSET REGULATION

         Under Department of Labor regulations governing what constitutes the
assets of a Plan or IRA ("Plan Assets") for purposes of ERISA and the related
prohibited transaction provisions of the Code (the "Plan Asset Regulation," 29
C.F.R. Sec. 2510.3-101), when a Plan or IRA acquires an equity interest in
another entity, and such interest does not represent a "publicly offered
security" nor a security issued by an investment company registered under the
1940 Act, the Plan's assets include both the equity interest and an undivided
interest in each of the underlying assets of the entity, unless it is
established either that the entity is an operating company or that equity
participation in the entity by "benefit plan investors," as



                                       74
<PAGE>   76

defined in the Plan Assets Regulation, is not "significant." For purposes of the
Plan Asset Regulation, the Trust will be neither an investment company nor an
operating company.

         Under the Plan Asset Regulation, equity participation by benefit plan
investors will not be considered "significant" on any date only if immediately
after the most recent acquisition of the capital securities, the aggregate
interest in the capital securities held by benefit plan investors will be less
than 25% of the aggregate outstanding principal amount of the capital
securities. Although it is possible that the equity participation by benefit
plan investors on any date will not be "significant" for purposes of the Plan
Asset Regulation, such a result cannot be assured. Consequently, if Plans, IRAs
or investors using assets of Plans purchase the capital securities, the Trust's
assets could be deemed to be "plan assets" of such Plans and/or IRAs for
purposes of the fiduciary responsibility provisions of ERISA and the prohibited
transactions rules of ERISA and the Code. Under ERISA and the Code, any person
who exercises any authority or control respecting the management or disposition
of the assets of a Plan or IRA is considered to be a fiduciary of such Plan or
IRA. The property trustee of the Trust could therefore become a fiduciary of the
Plans and IRAs that invest in the capital securities and be subject to the
general fiduciary requirements of ERISA in exercising its authority with respect
to the management of the assets of the Trust. However, the property trustee will
have only limited discretionary authority with respect to the Trust assets and
the remaining functions and responsibilities performed by the property trustee
will be for the most part custodial and ministerial in nature.

PROHIBITED TRANSACTIONS

         Each of the Trust, BancFirst Ohio (the obligor with respect to the
junior subordinated debentures held by the Trust) and their affiliates or the
property trustee may be a party in interest or a disqualified person with
respect to a Plan or IRA investing in the capital securities. Therefore, such
investment by a Plan or IRA may give rise to a prohibited transaction.
Consequently, before investing in the capital securities or acquiring junior
subordinated debentures, any person who is, or who is acquiring such securities
for, or on behalf of, a Plan or IRA should determine that either a statutory or
an administrative exemption from the prohibited transaction rules discussed
below or otherwise available is applicable to such investment in the capital
securities, or that such investment in, or acquisition of, such securities will
not result in a non-exempt prohibited transaction.

         The statutory or administrative exemptions from the prohibited
transaction rules under ERISA and the Code which may be available to a Plan or
IRA, which is investing in the capital securities include the following
(collectively referred to as the "ERISA Investor Exemptions"):

         -        Prohibited Transaction Class Exemption ("PTCE") 90-1,
                  regarding investments by insurance company pooled separate
                  accounts;
         -        PTCE 91-38, regarding investments by bank collective
                  investment funds;
         -        PTCE 84-14, regarding transactions effected by qualified
                  professional asset managers;
         -        PTCE 96-23, regarding transactions effected by in-house asset
                  managers; and o PTCE 95-60, regarding investments by insurance
                  company general accounts.

         No person who is, or who in acquiring capital securities is using the
assets of, a Plan or IRA may acquire capital securities unless one of the ERISA
Investor Exemptions or another applicable exemption is available to the Plan or
IRA, or such acquisition or holding of the capital securities will not result in
a non-exempt Prohibited Transaction. The acquisition of the capital securities
by any person who is, or who in acquiring such capital securities is using the
assets of, a Plan or IRA shall be deemed to constitute a representation by such
person to the property trustee of the Trust, BancFirst Ohio and the initial
purchaser either that:



                                       75
<PAGE>   77

         -        it is not a Plan, IRA, trustee or other person acting on
                  behalf of a Plan or IRA or other person or entity using the
                  assets of any Plan or IRA to finance such purchase; or
         -        such acquisition will not result in a prohibited transaction
                  under Section 406 of ERISA or Section 4975 of the Code for
                  which there is no applicable statutory or administrative
                  exemption.

         In the case of capital securities delivered in certificated form, the
purchaser will be required to make such representation, in writing, to the
trustee of the Trust, BancFirst Ohio and the initial purchaser.


         THE DISCUSSION OF ERISA HEREIN IS GENERAL IN NATURE AND IS NOT INTENDED
TO BE ALL INCLUSIVE. ANY FIDUCIARY OF A PLAN, IRA, GOVERNMENTAL PLAN OR CHURCH
PLAN CONSIDERING AN INVESTMENT IN THE CAPITAL SECURITIES SHOULD CONSULT WITH ITS
LEGAL ADVISORS REGARDING THE CONSEQUENCES OF SUCH INVESTMENT AND CONSIDER
WHETHER THE PLAN OR IRA CAN MAKE THE REPRESENTATIONS NOTED ABOVE.

         FURTHER, THE SALE OF INVESTMENTS TO PLANS AND IRAS IS IN NO RESPECT A
REPRESENTATION BY THE TRUST, BANCFIRST OHIO, THE PROPERTY TRUSTEE, THE INITIAL
PURCHASER OR ANY OTHER PERSON ASSOCIATED WITH THE SALE OF THE CAPITAL SECURITIES
THAT SUCH SECURITIES MEET ALL RELEVANT LEGAL REQUIREMENTS WITH RESPECT TO
INVESTMENTS BY PLANS AND IRAS GENERALLY OR ANY PARTICULAR PLAN, OR THAT SUCH

                       EXCHANGE OFFER; REGISTRATION RIGHTS

         We entered into a registration rights agreement with the Trust and the
initial purchaser for the benefit of the holders of the capital securities
wherein we and the Trust agreed, for the benefit of the holders of the capital
securities:

- -        to use our best efforts to file with the Commission within 150 days
         after the issue date the exchange offer registration statement relating
         to the exchange offer for (a) the exchange capital securities, which
         will have terms identical in all material respects to the capital
         securities (except that the exchange capital securities will not
         provide for any increase in the distribution rate thereon under the
         circumstances described below), (b) the exchange guarantee, which will
         have terms identical in all material respects to the guarantee, and (c)
         the exchange debentures, which will have terms identical in all
         material respects to the junior subordinated debentures (except that
         the exchange debentures will not provide for any liquidated damages)
         and
- -        to use our best efforts to cause the exchange offer registration
         statement to be declared effective under the Securities Act within 180
         days after the issue date. Promptly after the exchange offer
         registration statement has been declared effective, we will offer the
         exchange debentures in exchange for surrender of the junior
         subordinated debentures, and the property trustee will be required
         pursuant to the Indenture to so exchange all of the junior subordinated
         debentures held thereby, and the Trust will offer the exchange capital
         securities and we will offer the exchange guarantee in exchange for
         surrender of the capital securities and the guarantee, respectively. We
         and the Trust will keep the exchange offer open for not less than 30
         calendar days (or longer if required by applicable law) after the date
         notice of the exchange offer has been mailed to the holders of the
         capital securities and the junior subordinated debentures. For each
         capital security, guarantee or junior subordinated debenture validly
         tendered to the Trust or us, as the case may be, pursuant to the
         exchange offer and not validly withdrawn by the holder thereof, the
         holder of such capital security,



                                       76
<PAGE>   78

         guarantee or junior subordinated debenture will receive an exchange
         capital security having a liquidation amount equal to the liquidation
         amount of the tendered capital security, an exchange guarantee or an
         exchange debenture having a principal amount equal to the principal
         amount of the tendered junior subordinated debentures, as applicable.
         Distributions on each exchange capital security and interest on each
         exchange debenture will accrue from the last date on which a
         distribution or interest was paid on the capital security or junior
         subordinated debentures tendered in exchange therefor or, if no
         distribution or interest has been paid on such capital security or
         junior subordinated debenture, from the date of original issuance.

         Based on existing interpretations of the Securities Act by the staff of
the Commission set forth in several no-action letters to third parties, and
subject to the immediately following sentence, we and the Trust believe that the
exchange capital securities, exchange guarantee and exchange debentures issued
pursuant to the exchange offer may be offered for resale, resold and otherwise
transferred by the holders thereof (other than holders who are broker-dealers)
without further compliance with the registration and prospectus delivery
provisions of the Securities Act. However, any purchaser of capital securities
who is an affiliate of the Trust or us or who intends to participate in the
exchange offer for the purpose of distributing the exchange capital securities,
or any broker-dealer who purchased the capital securities from the Trust to
resell pursuant to Rule 144A or any other available exemption under the
Securities Act:

         -        will not be able to rely on the interpretation of the staff
                  set forth in the above-mentioned no-action letters;
         -        will not be entitled to tender its capital securities in the
                  exchange offer; and
         -        must comply with the registration and prospectus delivery
                  requirements of the Securities Act in connection with any sale
                  or transfer of the capital securities or junior subordinated
                  debentures and the guarantee unless such sale or transfer is
                  made pursuant to an exemption from such requirements.

         Neither us nor the Trust intends to seek our own no-action letter and
there can be no assurance that the staff would make a similar determination with
respect to the exchange capital securities, exchange guarantee and exchange
debentures as it has in such no-action letters to third parties.


         Each holder of the capital securities (other than certain specified
holders) who wishes to exchange the capital securities for exchange capital
securities in the exchange offer will be required to represent that:

         -        it is not an affiliate of the Trust or us;
         -        the exchange capital securities to be received by it were
                  acquired in the ordinary course of its business; and
         -        at the time of the exchange offer, it has no arrangement with
                  any person to participate in the distribution (within the
                  meaning of the Securities Act) of the exchange capital
                  securities.

         In addition, in connection with any resales of exchange capital
securities, any broker-dealer (a "participating broker-dealer") who acquired the
capital securities for its own account as a result of market-making or other
trading activities must deliver a prospectus meeting the requirements of the
Securities Act. The Commission has taken the position that participating
broker-dealers may fulfill their prospectus delivery requirements with respect
to the exchange capital securities (other than a resale of an unsold allotment
from the original sale of the capital securities) with the prospectus contained
in the exchange offer registration statement. Under the registration rights
agreement, the Trust is required to allow participating broker-dealers and other
persons, if any, subject to similar prospectus delivery requirements to use the
prospectus contained in the exchange offer registration statement in connection
with the resale of such exchange capital securities.


                                       77

         In the event:


         -        because of any change in law or in the applicable
                  interpretations of the staff, we and the Trust are not
                  permitted to effect the exchange offer;
         -        we shall determine in good faith that there is a reasonable
                  likelihood, or that a material uncertainty exists as to
                  whether, consummation of the exchange offer would result in a
                  material adverse tax consequence to us; or
         -        for any reason the exchange offer registration statement is
                  not declared effective within 180 days of the issue date, or
                  in certain other circumstances, then in lieu of effecting the
                  registration of the exchange capital securities pursuant to
                  the exchange offer registration statement, the administrative
                  trustees on behalf of the Trust will (x) promptly deliver to
                  the holders and the Delaware trustee written notice thereof
                  and (y) at our sole expense, (a) as promptly as practicable,
                  file the shelf registration statement, (b) use our best
                  efforts to cause the shelf registration statement to be
                  declared effective under the Securities Act and (c) use our
                  best efforts to keep effective the shelf registration
                  statement until the earlier of two years after the issue date
                  or such time as all of the applicable capital securities, the
                  guarantee and the junior subordinated debentures have been
                  sold thereunder or otherwise cease to be registrable
                  securities within the meaning of the registration rights
                  agreement. We will, in the event that a shelf registration
                  statement is filed, provide to each holder copies of the
                  prospectus that is a part of the shelf registration statement,
                  notify each such holder when the shelf registration statement
                  for the capital securities, the guarantee and the junior
                  subordinated debentures has become effective and take certain
                  other actions as are required to permit unrestricted resales
                  of the capital securities, the guarantee and the junior
                  subordinated debentures. A holder that sells capital
                  securities, the guarantee and the junior subordinated
                  debentures pursuant to the shelf registration statement
                  generally will be required to be named as a selling security
                  holder in the related prospectus and to deliver a prospectus
                  to purchasers, will be subject to certain of the civil
                  liability provisions under the Securities Act in connection
                  with such sales and will be bound by the provisions of the
                  registration rights agreement that are applicable to such a
                  holder (including certain indemnification rights and
                  obligations). In addition, each holder of capital securities
                  may be required to deliver information to be used in
                  connection with the shelf registration statement in order to
                  have its capital securities, guarantee and junior subordinated
                  debentures included in the shelf registration statement and to
                  benefit from the provisions of the succeeding paragraph.

         Each capital security, the guarantee and each junior subordinated
debenture contained a legend to the effect that the holder thereof, by its
acceptance thereof, was deemed to have agreed to be bound by the provisions of
the registration rights agreement. In that regard, each holder will be deemed to
have agreed that, upon receipt of notice from us of the occurrence of any event
which makes a statement in the prospectus which is part of the shelf
registration statement (or, in the case of participating broker-dealers, the
prospectus which is part of the exchange offer registration statement) untrue in
any material respect or which requires the making of any changes in such
prospectus in order to make the statements therein not misleading or of certain
other events specified in the registration rights agreement, such holder (or
participating broker-dealer, as the case may be) will suspend the sale of
capital securities, the guarantee and the junior subordinated debentures
pursuant to such prospectus until we have amended or supplemented such
prospectus to correct such misstatement or omission and has furnished copies of
the amended or supplemented prospectus to such holder (or participating
broker-dealer, as the case may be) or we have given notice that the sale of the
capital securities, the guarantee and the junior subordinated debentures may be
resumed, as the case may be.

         If we give such notice to suspend the sale of the capital securities,
the guarantee and the junior subordinated debentures, we will extend the
relevant period referred to above during which we and the Trust are required to
keep effective the shelf registration statement (or the period during which
participating broker-dealers are entitled to use the prospectus included in the
exchange offer registration statement in connection with the resale of exchange
capital securities, exchange guarantee or exchange



                                       78
<PAGE>   80

debentures, as the case may be) by the number of days during the period from and
including the date of the giving of such notice to and including the date when
holders shall have received copies of the supplemented or amended prospectus
necessary to permit resales of the capital securities, the guarantee and the
junior subordinated debentures or to and including the date on which we have
given notice that the sale of capital securities may be resumed, as the case may
be.

         If we or the Trust fail to comply with the registration rights
agreement or if the exchange offer registration statement or the shelf
registration statement fails to become effective, then liquidated damages (the
"liquidated damages") shall become payable in respect of the junior subordinated
debentures, and corresponding additional distributions (the "additional
distributions") shall become payable on the capital securities, as follows:

         (i) if neither the exchange offer registration statement nor a shelf
      registration statement is filed with the Commission on or prior to the
      150th day after the issue date (in the case of an exchange offer
      registration statement) or on or prior to the date required by the
      registration rights agreement (in the case of a shelf registration
      statement), liquidated damages shall accrue on the principal amount of the
      junior subordinated debentures, and additional distributions shall
      accumulate on the liquidation amount of the capital securities, each at a
      rate of 25 basis points per annum; or

         (ii) if neither the exchange offer registration statement nor a shelf
      registration statement is declared effective by the Commission on or prior
      to the 180th day after the issue date (in the case of an exchange offer
      registration statement) or on or prior to the later of the 30th day after
      the date such registration statement was required to be filed and the
      180th day after the issue date (in the case of a shelf registration
      statement), liquidated damages shall accrue on the principal amount of the
      junior subordinated debentures, and additional distributions shall
      accumulate on the liquidation amount of the capital securities, each at a
      rate of 25 basis points per annum; or

         (iii) if (A) the Trust has not exchanged exchange capital securities
      for all capital securities or we have not exchanged the exchange guarantee
      for the guarantee or exchange debentures for all junior subordinated
      debentures validly tendered, in accordance with the terms of the exchange
      offer, on or prior to the 45th day after the date on which the exchange
      offer registration statement was declared effective or (B) if applicable,
      the shelf registration statement has been declared effective and such
      shelf registration statement ceases to be effective or usable for resales
      at any time prior to the second anniversary of the issue date (other than
      after such time as all capital securities have been disposed of thereunder
      or otherwise cease to be registrable securities within the meaning of the
      registration rights agreement), then liquidated damages shall accrue on
      the principal amount of junior subordinated debentures, and additional
      distributions shall accumulate on the liquidation amount of the capital
      securities, each at a rate of 25 basis points per annum commencing on (x)
      the 46th day after such effective date, in the case of (A) above, or (y)
      the day such shelf registration statement ceases to be effective or usable
      for resales in the case of (B) above;

provided, however, that neither the liquidated damages rate on the junior
subordinated debentures, nor the additional distributions rate on the
liquidation amount of the capital securities, may exceed in the aggregate 25
basis points per annum; provided, further, however, that (1) upon the filing of
the exchange offer registration statement or a shelf registration statement (in
the case of clause (i) above), (2) upon the effectiveness of the exchange offer
registration statement or a shelf registration statement (in the case of clause
(ii) above), (3) upon the exchange of exchange capital securities, the exchange
guarantee and exchange debentures for all capital securities, the guarantee and
junior subordinated debentures tendered (in the case of clause (iii) (A) above),
or at such time as the shelf registration statement which had ceased to remain
effective or usable for resales (in the case of clause (iii) (B) above) again
becomes effective or usable for resales, liquidated damages on the junior
subordinated debentures and additional distributions on the liquidation amount
of the capital securities as a result of such clause (or the relevant subclause
thereof), as the case may be, shall cease to accrue.

                                       79
<PAGE>   81
         Any amounts of liquidated damages and additional distributions due
pursuant to the foregoing paragraphs will be payable in cash on October 15 and
April 15 of each year to the holders of record on the 1st day of the month in
which the relevant payment occurs.

         The registration rights agreement will be governed by, and construed in
accordance with, the laws of the State of New York, without regard to conflict
of law principles. The summary herein of certain provisions of the registration
rights agreement does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the
registration rights agreement, a form of which is available upon request to us.
See "Available Information." In addition, the information set forth above
concerning certain interpretations of and positions taken by the staff is not
intended to constitute legal advice, and you should consult your own legal
advisors with respect to such matters.


                              PLAN OF DISTRIBUTION

         Each broker-dealer that receives new securities for its own account in
the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of those securities. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new securities received in the exchange offer where
the old securities were acquired as a result of market-making activities or
other trading activities. We have agreed that, for a period of ___ days after
the completion of the exchange offer, we will make this prospectus, as amended
and supplemented, available to any broker-dealer for use in connection with any
such resale.

         We will not receive any proceeds from any sale of new securities issued
in the exchange offer by broker-dealers. New securities issued in the exchange
offer received by broker-dealers for their own account under the exchange offer
may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the new securities or a combination of such methods of resale, at
market prices prevailing at the time of resale, at prices related to such
prevailing market prices or at negotiated prices. Any such resale may be made
directly to purchasers to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such new securities. Any broker-dealer
that resells new securities that were received by it for its own account in the
exchange offer and any broker or dealer that participates in a distribution of
such new securities may be deemed to be an "underwriter" within the meaning of
the Securities Act, and profit on any such resale of new securities issued in
the exchange and any commission or concessions received by any such persons may
be deemed to be underwriting compensation under the Securities Act. The letter
of transmittal states that, by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.

         For a period of ___ days after the completion of the exchange offer, we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay all fees and expenses
incident to the exchange offer, other than the commissions or concessions of any
broker-dealers, and will indemnify the holders of the old securities, including
any broker-dealers, against certain liabilities, including liabilities under the
Securities Act. We note, however, that, in the opinion of the SEC,
indemnification against liabilities arising under federal securities laws is
against public policy and may be unenforceable.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Ohio Revised Code, Section 1701.13(E), allows indemnification by the
Registrant to any person made or threatened to be made a party to any
proceedings, other than a proceeding by or in the right of the Registrant, by
reason of the fact that he is or was a director, officer, employee or agent of
the Registrant, against expenses, including judgment and fines, if he acted in
good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the Registrant and, with respect to criminal actions, in which
he had no reasonable cause to believe that his conduct was unlawful. Similar
provisions apply to actions brought by or in the right of the Registrant, except
that no indemnification shall be made in such cases when the person shall have
been adjudged to be liable for negligence or misconduct to the Registrant unless
deemed otherwise by the court. Indemnification may be authorized by a majority
vote of a quorum of disinterested directors or upon the written opinion of
independent counsel or by the shareholders or by court order. The Registrant's
Code of Regulations extends such indemnification.

ITEM 22.  UNDERTAKINGS

         Each of the undersigned Registrants hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, as
amended, each filing of a Registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

         Each of the undersigned Registrants hereby also undertakes:

         (1) to file, during any period in which offers or sales are being made,
      post-effective amendment to this Registration Statement;

            (i) to include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933;


            (ii) to reflect in the prospectus any facts or events arising after
         the effective date of this Registration Statement (or the most recent
         post-effective amendment thereto) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in this Registration Statement. Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective Registration Statement; and

            (iii) to include any material information with respect to the plan
         of distribution not previously disclosed in this Registration Statement
         or any material change to such information in this Registration
         Statement; provided, however, that paragraphs (1) (i) and (1) (ii) do
         not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed by a Registrant pursuant to Section 13 or Section 15(d)
         of the Securities Exchange Act of 1934 that are incorporated by
         reference in this Registration Statement.

         (2) that, for the purpose of determining any liability under the
      Securities Act of 1933, each such post-effective amendment shall be deemed
      to be a new registration statement relating to the securities offered
      therein, and the offering of such securities at that time shall be deemed
      to be the in initial bona fide offering thereof.

         (3) to remove from registration by means of a post-effective amendment
      any of the securities being registered which remain unsold at the
      termination of the offering.

         (4) to deliver or cause to be delivered with the prospectus, to each
      person to whom the prospectus is sent or given, the latest annual report
      to security holders that is incorporated by reference in the prospectus
      and furnished pursuant to and meeting the requirements of Rule 14a-3 or
      Rule 14c-3 under the Securities Act of 1934, where interim financial
      information to be presented by Article 3 of Regulation S-X are not set
      forth in the prospectus, to deliver, or cause to be delivered to each
      person to whom the prospectus is sent or given, the latest quarterly
      report



                                       83
<PAGE>   85

      that is specifically incorporated by reference in the prospectus to
      provide such interim financial information.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
each undersigned Registrant pursuant to the provisions, or otherwise, each
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by each undersigned Registrant
of expenses incurred or paid by a director, officer or controlling person of
each Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, each Registrant will, unless in the opinion of its
counsel the matter has been settled by the controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.

         Each of the undersigned Registrants hereby undertakes to respond to
requests for information that is incorporated by reference into the Prospectus
pursuant to Item 4, 10(b), 11 or 13 of this Form within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

         Each of the undersigned Registrants hereby undertakes to supply by
means of a post-effective amendment all information concerning a transaction,
and the company being acquired or involved therein, that was not the subject of
and included in the registration statement when it became effective.

                                      -12-
<PAGE>   19

for crediting to the accounts of its participants pursuant to the instructions
of the Administrative Trustees; the Corporation upon any such presentation shall
execute one or more Global Securities in such aggregate principal amount and
deliver the same to the Debenture Trustee for authentication and delivery in
accordance with this Indenture; and payments on the Securities issued as a
Global Security will be made to the Depositary; and

                  (ii) if any Capital Securities are held in certificated form,
the related Definitive Securities may be presented to the Debenture Trustee, by
the Property Trustee and any Capital Security certificates which represent
Capital Securities other than Book-Entry Capital Securities ("Non Book-Entry
Capital Securities") will be deemed to represent beneficial interests in
Securities presented to the Debenture Trustee by the Property Trustee having an
aggregate principal amount equal to the aggregate liquidation amount of the Non
Book-Entry Capital Securities until such Capital Security certificates are

Securities with an equivalent aggregate principal amount that were presented by
the Property Trustee to the Debenture Trustee will be canceled.

         (b) The Global Securities shall represent the aggregate amount of
outstanding Securities from time to time endorsed thereon; PROVIDED, HOWEVER,
that the aggregate principal amount of outstanding Securities represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and prepayments. Any endorsement of a Global Security to
reflect the amount of any increase or decrease in the aggregate principal amount
of outstanding Securities represented thereby shall be made by the Debenture
Trustee, in accordance with instructions given by the Corporation as required by
this Section 2.05.

         (c) The Global Securities may be transferred, in whole but not in part,
only to the Depositary, to another nominee of the Depositary, or to a successor
Depositary selected or approved by the Corporation or to a nominee of such
successor Depositary.

unwilling or unable to continue as Depositary or the Depositary has ceased to be
a clearing agency registered under the Exchange Act, and, in each case, a
successor Depositary is not appointed by the Corporation within 90 days after
the Corporation receives such notice or becomes aware of such condition, as the
case may be, the Corporation will execute, and the Debenture Trustee, upon
receipt of a Corporation Order, will authenticate and make available for
delivery the Definitive Securities, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Security,
in exchange for such Global Security. If there is a Default or an Event of
Default, the Depositary shall have the right to exchange the Global Securities
for Definitive Securities. In addition, the Corporation may at any time
determine that the Securities shall no longer be represented by a Global
Security. In the event of such an Event of Default or such a determination, the
Corporation shall execute, and subject to Section 2.07, the Debenture Trustee,
upon receipt of an Officers' Certificate evidencing such determination by the
Corporation and a Corporation Order,


                                      -13-
<PAGE>   20

will authenticate and make available for delivery the Definitive Securities, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security, in exchange for such Global Security.
Upon the exchange of the Global Security for such Definitive Securities, in
authorized denominations, the Global Security shall be canceled by the Debenture
Trustee. Such Definitive Securities issued in exchange for the Global Security
shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Debenture Trustee. The Debenture Trustee shall
deliver such Definitive Securities to the Depositary for delivery to the Persons
in whose names such Definitive Securities are so registered.

         SECTION 2.06  INTEREST.

         (a) Each Security will bear interest, at the rate of 9.875% per annum
(the "Coupon Rate"), from the most recent date to which interest has been paid
or duly provided for or, if no interest has been paid or duly provided for, from
October 18, 1999, until the principal thereof becomes due and payable, and at
the Coupon Rate on any overdue principal (and premium, if any) and (to the
extent that payment of such interest is enforceable under applicable law) on any
overdue installment of interest, compounded semi-annually, payable (subject to
the provisions of Article XVI) semi-annually in arrears on April 15 and October
15 of each year, commencing April 15, 2000 (each, an "Interest Payment Date"),

registered at the close of business on the regular record date for such interest
installment, which shall be the first day of the month in which the relevant
Interest Payment Date falls.

         (b) The amount of interest payable on the Securities shall be computed
on the basis of 360-day year of twelve 30-day months.

         (c) During such time as the Property Trustee is the holder of any
Securities, the Corporation shall pay any additional amounts on the Securities
as may be necessary in order that the amount of Distributions then due and
payable by the Trust on the outstanding Trust Securities shall not be reduced as
a result of any additional taxes, duties and other governmental charges to which
the Trust has become subject as a result of a Tax Event ("Additional Sums").

         SECTION 2.07 TRANSFER AND EXCHANGE.

         (a)      TRANSFER RESTRICTIONS.

                  (i) The Initial Securities, and those Exchange Securities with
respect to which any Person described in Section 2.04(b)(A), (B) or (C) is the
beneficial owner, may not be transferred except in compliance with the legend
contained in Exhibit A unless otherwise determined by the Corporation in
accordance with applicable law. Upon any distribution of the Securities
following a Dissolution Event, the Corporation and the Debenture Trustee shall
enter into a supplemental indenture pursuant to Section 9.01 to provide for the
transfer restrictions and procedures with respect to the Securities
substantially similar to those contained in the Declaration to the extent
applicable in the circumstances existing at such time.

in a block having an aggregate principal amount of less than $100,000 shall be
deemed to be voided and of no legal effect whatsoever. Any such purported
transferee shall be deemed not to be a holder of such Securities for any
purpose, including, but not limited to the receipt of payments on such
Securities, and such purported transferee shall be deemed to have no interest
whatsoever in such Securities.

         (b) GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES. To permit
registrations of transfers and exchanges, the Corporation shall execute and the
Debenture Trustee shall authenticate Definitive Securities and Global Securities
at the request of the security registrar for the Securities. All Definitive
Securities and Global Securities issued upon any registration of transfer or
exchange of Definitive Securities or Global Securities shall be the valid
obligations of the Corporation, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Definitive Securities or Global
Securities surrendered upon such registration of transfer or exchange.

         No service charge shall be made to a holder for any registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in
connection therewith.

         The Corporation shall not be required to: (i) issue, register the
transfer of or exchange Securities during a period beginning at the opening of
business 15 days before the day of mailing of a notice of prepayment or any
notice of selection of Securities for prepayment under Article XIV hereof and
ending at the close of business on the day of such mailing; or (ii) register the
transfer of or exchange any Security so selected for prepayment in whole or in
part, except the nonprepaid portion of any Security being prepaid in part.

         Prior to due presentment for the registration of a transfer of any
Security, the Debenture Trustee, the Corporation and any agent of the Debenture
Trustee or the Corporation may deem and treat the Person in whose name any
Security is registered as the absolute owner of such Security for the purpose of
receiving payment of principal of and premium, if any, and interest on such
Securities, and none of the Debenture Trustee, the Corporation or any agents of
the Debenture Trustee or the Corporation shall be affected by notice to the
contrary.

         (c) EXCHANGE OF INITIAL SECURITIES FOR EXCHANGE SECURITIES. The Initial
Securities may be exchanged for Exchange Securities pursuant to the terms of the
Exchange Offer. The Debenture Trustee shall make the exchange as follows:

         The Corporation shall present the Debenture Trustee with an Officers'
Certificate certifying the following:

         (A)      upon issuance of the Exchange Securities, the transactions
                  contemplated by the Exchange Offer have been consummated; and

         (B)      the principal amount of Initial Securities properly tendered
                  in the Exchange Offer that are represented by a Global
                  Security, the principal amount of Initial Securities


                                      -15-
<PAGE>   22

                  properly tendered in the Exchange Offer that are represented
                  by Definitive Securities, the name of each holder of such
                  Definitive Securities, the principal amount properly tendered
                  in the Exchange Offer by each such holder and the name and
                  address to which Definitive Securities for Exchange Securities
                  shall be registered and sent for each such holder.

         The Debenture Trustee, upon receipt of (i) such Officers' Certificate,
(ii) an Opinion of Counsel (x) to the effect that the Exchange Securities have
been registered under Section 5 of the Securities Act and the Indenture has been
qualified under the Trust Indenture Act and (y) with respect to the matters set
forth in Section 3(q) of the Registration Rights Agreement and (iii) a
Corporation Order, shall authenticate (A) a Global Security representing
Exchange Securities in aggregate principal amount equal to the aggregate
principal amount of Initial Securities represented by a Global Security
indicated in such Officers' Certificate as having been properly tendered and (B)
Definitive Securities representing Exchange Securities registered in the names
of, and in the principal amounts indicated in, such Officers' Certificate.

         If the principal amount of the Global Security for the Exchange
Securities is less than the principal amount of the Global Security for the
Initial Securities, the Debenture Trustee shall make an endorsement on such
Global Security for Initial Securities indicating a reduction in the principal
amount represented thereby.

         The Debenture Trustee shall deliver such Definitive Securities
representing Exchange Securities to the holders thereof as indicated in such
Officers' Certificate.

         SECTION 2.08 REPLACEMENT SECURITIES.

         If any mutilated Security is surrendered to the Debenture Trustee, or
the Corporation and the Debenture Trustee receive evidence to their satisfaction
of the destruction, loss or theft of any Security, the Corporation shall issue
and the Debenture Trustee shall authenticate a replacement Security if the
Debenture Trustee's requirements for replacements of Securities are met. An
indemnity bond must be supplied by the holder that is sufficient in the judgment
of the Debenture Trustee and the Corporation to protect the Corporation, the
Debenture Trustee, any agent thereof or any Authenticating Agent from any loss
that any of them may suffer if a Security is replaced. The Corporation or the
Debenture Trustee may charge for its expenses in replacing a Security.

         Every replacement Security is an obligation of the Corporation and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Securities duly issued hereunder.

         SECTION 2.09 TEMPORARY SECURITIES.

         Pending the preparation of Definitive Securities, the Corporation may
execute, and upon Corporation Order the Debenture Trustee shall authenticate and
make available for delivery, temporary Securities that are printed,
lithographed, typewritten, mimeographed or otherwise reproduced, in any
authorized denomination, substantially of the tenor of the Definitive Securities
in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and



                                      -16-
<PAGE>   23

other variations as the Officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.

         If temporary Securities are issued, the Corporation shall cause
Definitive Securities to be prepared without unreasonable delay. The Definitive
Securities shall be printed, lithographed or engraved, or provided by any
combination thereof, or in any other manner permitted by the rules and
regulations of any applicable securities exchange, all as determined by the
Officers executing such Definitive Securities. After the preparation of
Definitive Securities, the temporary Securities shall be exchangeable for
Definitive Securities upon surrender of the temporary Securities at the office
or agency maintained by the Corporation for such purpose pursuant to Section
3.02 hereof, without charge to the holder thereof. Upon surrender for
cancellation of any one or more temporary Securities, the Corporation shall
execute, and the Debenture Trustee shall authenticate and make available for
delivery, in exchange therefor the same aggregate principal amount of Definitive
Securities of authorized denominations. Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as Definitive Securities.

         SECTION 2.10  CANCELLATION.

         The Corporation at any time may deliver Securities to the Debenture
Trustee for cancellation. The Debenture Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment,
replacement or cancellation and shall return such canceled Securities to the
Corporation. The Corporation may not issue new Securities to replace Securities
that have been prepaid or paid or that have been delivered to the Debenture
Trustee for cancellation.

         SECTION 2.11 DEFAULTED INTEREST.

         Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the holder on the
relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Corporation, at its election, as
provided in clause (a) or clause (b) below:

                  (a) The Corporation may make payment of any Defaulted Interest
         on Securities to the Persons in whose names such Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a special record date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner: the Corporation
         shall notify the Debenture Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each such Security and the
         date of the proposed payment, and at the same time the Corporation
         shall deposit with the Debenture Trustee an amount of money equal to
         the aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Debenture
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon, the Debenture Trustee shall fix a special record date for
         the payment of such Defaulted Interest which shall not be more than 15
         nor less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Debenture Trustee of the
         notice of



                                      -17-
<PAGE>   24

         the proposed payment. The Debenture Trustee shall promptly notify the
         Corporation of such special record date and, in the name and at the
         expense of the Corporation, shall cause notice of the proposed payment
         of such Defaulted Interest and the special record date therefor to be
         mailed, first class postage prepaid, to each Securityholder at his or
         her address as it appears in the Security Register, not less than 10
         days prior to such special record date. Notice of the proposed payment
         of such Defaulted Interest and the special record date therefor having
         been mailed as aforesaid, such Defaulted Interest shall be paid to the
         Persons in whose names such Securities (or their respective Predecessor
         Securities) are registered on such special record date and shall be no
         longer payable pursuant to the following clause (b).

                  (b) The Corporation may make payment of any Defaulted Interest
         on any Securities in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which such Securities may be
         listed, and upon such notice as may be required by such exchange, if,
         after notice given by the Corporation to the Debenture Trustee of the
         proposed payment pursuant to this clause, such manner of payment shall
         be deemed practicable by the Debenture Trustee.

         SECTION 2.12  CUSIP NUMBERS.

         The Corporation in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Debenture Trustee shall use "CUSIP"
numbers in notices of prepayment as a convenience to Securityholders; PROVIDED,
HOWEVER, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a prepayment and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such prepayment shall
not be affected by any defect in or omission of such numbers. The Corporation
will promptly notify the Debenture Trustee of any change in the CUSIP numbers.


                                   ARTICLE III
                     PARTICULAR COVENANTS OF THE CORPORATION

         SECTION 3.01 PAYMENT OF PRINCIPAL AND INTEREST.

         The Corporation covenants and agrees for the benefit of the holders of
the Securities that it will duly and punctually pay or cause to be paid the
principal of and premium, if any, and interest on the Securities at the place,
at the respective times and in the manner provided herein. The Corporation
further covenants to pay any and all amounts due in respect of the Securities,
including, without limitation, Additional Sums, as may be required pursuant to
Section 2.06(c), Liquidated Damages, if any, on the dates and in the manner
required under the Registration Rights Agreement or the Liquidated Damages
Agreement and Compounded Interest, as may be required pursuant to Section 16.01.

<PAGE>   25

         SECTION 3.02 OFFICES FOR NOTICES AND PAYMENTS, ETC.

         So long as any of the Securities remain outstanding, the Corporation
will maintain in Wilmington, Delaware an office or agency where the Securities
may be presented for payment, an office or agency where the Securities may be
presented for registration of transfer and for exchange as in this Indenture
provided and an office or agency where notices and demands to or upon the
Corporation in respect of the Securities or this Indenture may be served. The
Corporation will give to the Debenture Trustee written notice of the location of
any such office or agency and of any change of location thereof. Until otherwise
designated from time to time by the Corporation in a notice to the Debenture
Trustee, any such office or agency for all of the above purposes shall be the
Principal Office of the Debenture Trustee. In case the Corporation shall fail to
maintain any such office or agency in Wilmington, Delaware or shall fail to give
such notice of the location or of any change in the location thereof,
presentations and demands may be made and notices may be served at the Principal
Office of the Debenture Trustee.

         In addition to any such office or agency, the Corporation may from time
to time designate one or more offices or agencies outside Wilmington, Delaware
where the Securities may be presented for payment, for registration of transfer
and for exchange and where notices and demands to or upon the Corporation in
respect of the Securities or this Indenture may be served in the manner provided
in this Indenture, and the Corporation may from time to time rescind such
designation, as the Corporation may deem desirable or expedient; PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Corporation of its obligation to maintain any such office or agency in
Wilmington, Delaware for the purposes above mentioned. The Corporation will give
to the Debenture Trustee prompt written notice of any such designation or
rescission thereof.

         SECTION 3.03 APPOINTMENTS TO FILL VACANCIES IN DEBENTURE TRUSTEE'S
OFFICE.

         The Corporation, whenever necessary to avoid or fill a vacancy in the
office of Debenture Trustee, will appoint, in the manner provided in Section
6.10, a Debenture Trustee, so that there shall at all times be a Debenture
Trustee hereunder.

         SECTION 3.04 PROVISION AS TO PAYING AGENT.

         (a) If the Corporation shall appoint a paying agent other than the
Debenture Trustee with respect to the Securities, it will cause such paying
agent to execute and deliver to the Debenture Trustee an instrument in which
such agent shall agree with the Debenture Trustee, subject to the provisions of
this Section 3.04,

                  (1)      that it will hold all sums held by it as such agent
                           for the payment of the principal of and premium, if
                           any, or interest on the Securities (whether such sums
                           have been paid to it by the Corporation or by any
                           other obligor on the Securities) in trust for the
                           benefit of the holders of the Securities; and

                  (2)      that it will give the Debenture Trustee notice of any
                           failure by the Corporation (or by any other obligor
                           on the Securities) to make any payment of the
                           principal of or premium, if any, or interest
                           (including Additional Sums


                                      -19-

                           shall be due and payable.

         (b) If the Corporation shall act as its own paying agent, it will, on
or before each due date of the principal of and premium, if any, or interest on
the Securities, set aside, segregate and hold in trust for the benefit of the
holders of the Securities a sum sufficient to pay such principal, premium or
interest so becoming due and will notify the Debenture Trustee of any failure to
take such action and of any failure by the Corporation (or by any other obligor
under the Securities) to make any payment of the principal, premium or interest
on the Securities when the same shall become due and payable.

         (c) Anything in this Section 3.04 to the contrary notwithstanding, the
Corporation may, at any time, for the purpose of obtaining a satisfaction and
discharge with respect to the Securities hereunder, or for any other reason, pay
or cause to be paid to the Debenture Trustee all sums payable with respect to
the Securities, such sums to be held by the Debenture Trustee upon the trusts
herein contained.

         (d) Anything in this Section 3.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 3.04 is subject to
Sections 11.03 and 11.04.

         SECTION 3.05 CERTIFICATE TO DEBENTURE TRUSTEE.

         The Corporation will deliver to the Debenture Trustee on or before 120
days after the end of each fiscal year of the Corporation, commencing with the

contained herein, stating whether or not they have knowledge of any such Default
and, if so, specifying each such Default of which the signers have knowledge,
the nature thereof and the action, if any, the Corporation intends to undertake
as a result of such Default.

         SECTION 3.06 COMPLIANCE WITH CONSOLIDATION PROVISIONS.

         The Corporation will not, while any of the Securities remain

securities of any Subsidiary of the Corporation (including Other Guarantees) if
such guarantee ranks pari passu with or junior in right of payment to the
Securities (other than (a) dividends or distributions in shares of, or options,
warrants or rights to subscribe for or purchase shares of, Common Stock), (b)
any declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
as a result of a reclassification of the Corporation's capital stock or the

payment of any obligations under the Capital Securities Guarantee or (3) the
Corporation shall have given notice of its election to exercise its right to
commence an Extended Interest Payment Period and shall not have rescinded such
notice, and such Extended Interest Payment Period or any extension thereof shall

         In the event Securities are issued to the Trust or a trustee of such
Trust in connection with the issuance of Trust Securities by the Trust, for so
long as such Trust Securities remain outstanding, the Corporation (i) will

<PAGE>   29

         (a)      on a semi-annual basis on each regular record date for the
                  Securities, a list, in such form as the Debenture Trustee may
                  reasonably require, of the names and addresses of the

Securities.

         SECTION 4.02 PRESERVATION AND DISCLOSURE OF LISTS.

         (a) The Debenture Trustee shall preserve, in as current a form as is

furnished to it as provided in Section 4.01 upon receipt of a new list so
furnished.

         (b) In case three or more holders of Securities (hereinafter referred
to as "applicants") apply in writing to the Debenture Trustee and furnish to the
Debenture Trustee reasonable proof that each such applicant has owned a Security
for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
holders of Securities or with holders of all Securities with respect to their
rights under this Indenture and is accompanied by a copy of the form of proxy or
other communication which such applicants propose to transmit, then the
Debenture Trustee shall within five Business Days after the receipt of such
application, at its election, either:

                  (1)      afford such applicants access to the information
                           preserved at the time by the Debenture Trustee in
                           accordance with the provisions of subsection (a) of
                           this Section 4.02, or

                  (2)      inform such applicants as to the approximate number
                           of holders of all Securities whose names and
                           addresses appear in the information preserved at the
                           time by the Debenture Trustee in accordance with the
                           provisions of subsection (a) of this Section 4.02,
                           and as to the approximate cost of mailing to such
                           Securityholders the form of proxy or other
                           communication, if any, specified in such application.

         If the Debenture Trustee shall elect not to afford such applicants
access to such information, the Debenture Trustee shall, upon the written
request of such applicants, mail to each Securityholder whose name and address
appear in the information preserved at the time by the Debenture Trustee in
accordance with the provisions of subsection (a) of this Section 4.02 a copy of
the form of proxy or other communication which is specified in such request with
reasonable promptness after a tender to the Debenture Trustee of the material to
be mailed and of payment, or provision for the payment, of the reasonable
expenses of mailing, unless within five Business Days after such tender, the



                                      -23-
<PAGE>   30

Debenture Trustee shall mail to such applicants and file with the Commission,
together with a copy of the material to be mailed, a written statement to the
effect that, in the opinion of the Debenture Trustee, such mailing would be
contrary to the best interests of the holders of Securities or would be in
violation of applicable law. Such written statement shall specify the basis of
such opinion. If the Commission, after opportunity for a hearing upon the
objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if, after the entry of an order
sustaining one or more of such objections, the Commission shall find, after
notice and opportunity for hearing, that all the objections so sustained have
been met and shall enter an order so declaring, the Debenture Trustee shall mail
copies of such material to all such Securityholders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the
Debenture Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

         (c) Each and every holder of Securities, by receiving and holding the
same, agrees with the Corporation and the Debenture Trustee that neither the
Corporation nor the Debenture Trustee nor any paying agent shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the holders of Securities in accordance with the provisions of
subsection (b) of this Section 4.02, regardless of the source from which such
information was derived, and that the Debenture Trustee shall not be held
accountable by reason of mailing any material pursuant to a request made under
said subsection (b).

         SECTION 4.03 REPORTS BY THE CORPORATION.

         (a) The Corporation covenants and agrees to file with the Debenture
Trustee, within 15 days after the date on which the Corporation is required to
file the same with the Commission, copies of the annual reports and of the
information, documents and other reports (or copies of such portions of any of
the foregoing as said Commission may from time to time by rules and regulations
prescribe) which the Corporation may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the
Corporation is not required to file information, documents or reports pursuant
to either of such sections, then to provide to the Debenture Trustee, such of
the supplementary and periodic information, documents and reports which would
have been required pursuant to Section 13 of the Exchange Act in respect of a
security listed and registered on a national securities exchange as may be
prescribed from time to time in such rules and regulations. The Corporation also
covenants and agrees to comply with the provisions of Section 314(a) of the
Trust Indenture Act.

         (b) The Corporation covenants and agrees to file with the Debenture
Trustee and the Commission, in accordance with the rules and regulations
prescribed from time to time by said Commission, such additional information,
documents and reports with respect to compliance by the Corporation with the
conditions and covenants provided for in this Indenture as may be required from
time to time by such rules and regulations.

         (c) The Corporation covenants and agrees to transmit by mail to all
holders of Securities, as the names and addresses of such holders appear upon
the Security Register, within 30 days after the filing thereof with the
Debenture Trustee, such summaries of any information, documents and



                                      -24-
<PAGE>   31

reports required to be filed by the Corporation pursuant to subsections (a) and
(b) of this Section 4.03 as may be required by rules and regulations prescribed
from time to time by the Commission.

         (d) Delivery of such reports, information and documents to the
Debenture Trustee is for informational purposes only and the Debenture Trustee's
receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Corporation's compliance with any of its covenants hereunder (as to which
the Debenture Trustee is entitled to rely exclusively on Officers'
Certificates).

         (e) So long as is required for an offer or sale of the Securities to
qualify for an exemption under Rule 144A under the Securities Act, the
Corporation shall, upon request, provide the information required by clause
(d)(4) thereunder to each Securityholder and to each beneficial owner and
prospective purchaser of Securities identified by each Securityholder of
Restricted Securities, unless such information is furnished to the Commission
pursuant to Section 13 or l5(d) of the Exchange Act.

         SECTION 4.04 REPORTS BY THE DEBENTURE TRUSTEE.

         (a) The Debenture Trustee shall transmit to Securityholders such
reports concerning the Debenture Trustee and its actions under this Indenture as
may be required pursuant to the Trust Indenture Act at the times and in the
manner provided pursuant thereto. If required by Section 313(a) of the Trust
Indenture Act, the Debenture Trustee shall, within 60 days after the date
hereof, and no later than the anniversary date hereof in each succeeding year,
deliver to Securityholders a brief report, dated as of each such date which
complies with the provisions of such Section 313(a).

         (b) A copy of each such report shall, at the time of such transmission
to Securityholders, be filed by the Debenture Trustee with each stock exchange,
if any, upon which the Securities are listed, with the Commission and with the
Corporation. The Corporation will promptly notify the Debenture Trustee when the
Securities are listed on any stock exchange.

                      REMEDIES OF THE DEBENTURE TRUSTEE AND
                      SECURITYHOLDERS UPON EVENT OF DEFAULT

         SECTION 5.01 EVENTS OF DEFAULT.

         One or more of the following events of default shall constitute an
Event of Default hereunder (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

         (a)      default in the payment of any interest (including Compounded
                  Interest and Additional Sums, if any) or Liquidated Damages,
                  if any, on the Securities or any Other Debentures (about which
                  a Responsible Officer of the Debenture Trustee has


                                      -25-

                  actual knowledge) when due, and continuance of such default
                  for a period of 30 days; PROVIDED, HOWEVER, that a valid
                  extension of an interest payment period by the Corporation in
                  accordance with the terms hereof or thereof shall not
                  constitute a default in the payment of interest for this
                  purpose; or

         (b)      default in the payment of any principal of (or premium, if
                  any, on) the Securities or any Other Debentures (about which a
                  Responsible Officer of the Debenture Trustee has actual
                  knowledge) when due, whether at maturity, upon prepayment, by
                  declaration of acceleration of maturity or otherwise; or

         (c)      default in the performance, or breach in any material respect,
                  of any covenant or warranty of the Corporation in this
                  Indenture (other than a covenant or warranty a default in
                  whose performance or whose breach is elsewhere in this Section
                  specifically dealt with), and continuance of such default or
                  breach for a period of 90 days after there has been given, by
                  registered or certified mail, to the Corporation by the
                  Debenture Trustee or to the Corporation and the Debenture
                  Trustee by the holders of at least 25% in aggregate principal
                  amount of the outstanding Securities a written notice
                  specifying such default or breach and requiring it to be
                  remedied and stating that such notice is a "Notice of Default"
                  hereunder; or

         (d)      a court having jurisdiction in the premises shall enter a
                  decree or order for relief in respect of the Corporation in an
                  involuntary case under any applicable bankruptcy, insolvency
                  or other similar law now or hereafter in effect, or appointing
                  a receiver, liquidator, assignee, custodian, trustee,
                  sequestrator (or similar official) of the Corporation or for
                  any substantial part of its property, or ordering the
                  winding-up or liquidation of its affairs and such decree or
                  order shall remain unstayed and in effect for a period of 90
                  consecutive days; or

         (e)      the Corporation shall commence a voluntary case under any
                  applicable bankruptcy, insolvency or other similar law now or
                  hereafter in effect, shall consent to the entry of an order
                  for relief in an involuntary case under any such law, or shall
                  consent to the appointment of or taking possession by a
                  receiver, liquidator, assignee, trustee, custodian,
                  sequestrator (or other similar official) of the Corporation or
                  of any substantial part of its property, or shall make any
                  general assignment for the benefit of creditors, or shall fail
                  generally to pay its debts as they become due.

         If an Event of Default with respect to Securities at the time
outstanding occurs and is continuing, then in every such case the Debenture
Trustee or the holders of not less than 25% in aggregate principal amount of the
Securities then outstanding may declare the principal amount of all Securities
to be due and payable immediately, by a notice in writing to the Corporation
(and to the Debenture Trustee if given by the holders of the outstanding
Securities), and upon any such declaration the same shall become immediately due
and payable.

         The foregoing provisions, however, are subject to the condition that
if, at any time after the principal of the Securities shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter



                                      -26-
<PAGE>   33

provided, (i) the Corporation shall pay or shall deposit with the Debenture
Trustee a sum sufficient to pay (A) all matured installments of interest
(including Compounded Interest and Additional Sums, if any) and Liquidated
Damages, if any, on all the Securities and the principal of and premium, if any,
on any and all Securities which shall have become due otherwise than by
acceleration (with interest upon such principal and premium, if any, and, to the
extent that payment of such interest is enforceable under applicable law, on
overdue installments of interest, at the same rate as the rate of interest
specified in the Securities to the date of such payment or deposit) and (B) such
amount as shall be sufficient to cover compensation due to the Debenture Trustee
and each predecessor Debenture Trustee, their respective agents, attorneys and
counsel, pursuant to Section 6.06, and (ii) any and all Events of Default under
the Indenture, other than the non-payment of the principal of the Securities
which shall have become due solely by such declaration of acceleration, shall
have been cured, waived or otherwise remedied as provided herein, then, in every
such case, the holders of a majority in aggregate principal amount of the
Securities then outstanding, by written notice to the Corporation and to the
Debenture Trustee, may rescind and annul such declaration and its consequences,
but no such waiver or rescission and annulment shall extend to or shall affect
any subsequent default or shall impair any right consequent thereon.

         In case the Debenture Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Debenture Trustee, then and in every
such case the Corporation, the Debenture Trustee and the holders of the
Securities shall be restored respectively to their several positions and rights
hereunder, and all rights, remedies and powers of the Corporation, the Debenture
Trustee and the holders of the Securities shall continue as though no such
proceeding had been taken.

         SECTION 5.02  PAYMENT OF SECURITIES ON DEFAULT; SUIT THEREFOR.

         The Corporation covenants that (a) in case default shall be made in the
payment of any installment of interest (including Compounded Interest and
Additional Sums, if any) and Liquidated Damages, if any, on any of the
Securities as and when the same shall become due and payable, and such default
shall have continued for a period of 30 days, or (b) in case default shall be
made in the payment of the principal of or premium, if any, on any of the
Securities as and when the same shall have become due and payable, whether at
maturity of the Securities or upon prepayment or by declaration or otherwise,
then, upon demand of the Debenture Trustee, the Corporation will pay to the
Debenture Trustee, for the benefit of the holders of the Securities, the whole
amount that then shall have become due and payable on all such Securities for
principal and premium, if any, or interest (including Compounded Interest and
Additional Sums, if any) and Liquidated Damages, if any, or both, as the case
may be, with interest upon the overdue principal and premium, if any, and (to
the extent that payment of such interest is enforceable under applicable law
and, if the Securities are held by the Trust or a trustee of such Trust, without
duplication of any other amounts paid by the Trust or a trustee in respect
thereof) upon the overdue installments of interest (including Compounded
Interest and Additional Sums, if any) and Liquidated Damages, if any, at the
rate borne by the Securities; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
reasonable compensation to the Debenture Trustee, its agents, attorneys and
counsel, and any other amount due to the Debenture Trustee pursuant to Section
6.06.



                                      -27-
<PAGE>   34

         In case the Corporation shall fail forthwith to pay such amounts upon
such demand, the Debenture Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any actions or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Corporation or any other
obligor on the Securities and collect in the manner provided by law out of the
property of the Corporation or any other obligor on the Securities, wherever
situated, the moneys adjudged or decreed to be payable.

         In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Corporation or any other obligor on the Securities
under Title 11, United States Code, or any other applicable law, or in case a
receiver or trustee shall have been appointed for the property of the
Corporation or such other obligor, or in the case of any other similar judicial
proceedings relative to the Corporation or other obligor upon the Securities, or
to the creditors or property of the Corporation or such other obligor, the
Debenture Trustee, irrespective of whether the principal of the Securities shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Debenture Trustee shall have made any demand
pursuant to the provisions of this Section 5.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a
claim or claims for the whole amount of principal and interest owing and unpaid
in respect of the Securities and, in case of any judicial proceedings, to file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Debenture Trustee (including any
claim for amounts due to the Debenture Trustee pursuant to Section 6.06) and of
the Securityholders allowed in such judicial proceedings relative to the
Corporation or any other obligor on the Securities, or to the creditors or
property of the Corporation or such other obligor, unless prohibited by
applicable law and regulations, to vote on behalf of the holders of the
Securities in any election of a trustee or a standby trustee in arrangement,
reorganization, liquidation or other bankruptcy or insolvency proceedings or
person performing similar functions in comparable proceedings, and to collect
and receive any moneys or other property payable or deliverable on any such
claims, and to distribute the same after the deduction of its charges and
expenses; and any receiver, assignee or trustee in bankruptcy or reorganization
is hereby authorized by each of the Securityholders to make such payments to the
Debenture Trustee, and, in the event that the Debenture Trustee shall consent to
the making of such payments directly to the Securityholders, to pay to the
Debenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to, and expenses of, the Debenture Trustee, each predecessor
Debenture Trustee and their respective agents, attorneys and counsel, and all
other amounts due to the Debenture Trustee pursuant to Section 6.06.

         Nothing herein contained shall be construed to authorize the Debenture
Trustee to authorize or consent to or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any holder thereof or to
authorize the Debenture Trustee to vote in respect of the claim of any
Securityholder in any such proceeding.

         All rights of action and of asserting claims under this Indenture, or
under any of the Securities, may be enforced by the Debenture Trustee without
the possession of any of the Securities, or the production thereof on any trial
or other proceeding relative thereto, and any such suit or proceeding instituted
by the Debenture Trustee shall be brought in its own name as trustee of an



                                      -28-
<PAGE>   35

express trust, and any recovery of judgment shall be for the ratable benefit of
the holders of the Securities.

         In any proceedings brought by the Debenture Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Debenture Trustee shall be a party), the Debenture Trustee shall be
held to represent all the holders of the Securities, and it shall not be
necessary to make any holders of the Securities parties to any such proceedings.

         SECTION 5.03  APPLICATION OF MONEYS COLLECTED BY DEBENTURE TRUSTEE.

         Any moneys collected by the Debenture Trustee shall be applied in the
following order, at the date or dates fixed by the Debenture Trustee for the
distribution of such moneys, upon presentation of the Securities in respect of
which moneys have been collected, and stamping thereon the payment, if only
partially paid, and upon surrender thereof if fully paid:

         First: To the payment of costs and expenses of collection applicable to
the Securities and all other amounts due to the Debenture Trustee under Section
6.06;

         Second: To the payment of all Senior Indebtedness of the Corporation if
and to the extent required by Article XV;

         Third: To the payment of the amounts then due and unpaid upon
Securities for principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) and Liquidated Damages, if any,
on the Securities, in respect of which or for the benefit of which money has
been collected, ratably, without preference of priority of any kind, according
to the amounts due on such Securities for principal (and premium, if any) and
interest, respectively; and

         Fourth: To the Corporation.

         SECTION 5.04 PROCEEDINGS BY SECURITYHOLDERS.

         No holder of any Security shall have any right by virtue of or by
availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such holder previously shall have given to the Debenture
Trustee written notice of an Event of Default and of the continuance thereof
with respect to the Securities specifying such Event of Default, as hereinbefore
provided, and unless also the holders of not less than 25% in aggregate
principal amount of the Securities then outstanding shall have made written
request upon the Debenture Trustee to institute such action, suit or proceeding
in its own name as Debenture Trustee hereunder and shall have offered to the
Debenture Trustee such reasonable indemnity as it may require against the costs,
expenses and liabilities to be incurred therein or thereby, and the Debenture
Trustee for 60 days after its receipt of such notice, request and offer of
indemnity shall have failed to institute any such action, suit or proceeding, it
being understood and intended, and being expressly covenanted by the taker and
holder of every Security with every other taker and holder and the Debenture
Trustee, that no one or more holders of Securities shall have any right in any
manner whatever by virtue of or by availing itself of any provision of this
Indenture to affect,



                                      -29-
<PAGE>   36

disturb or prejudice the rights of any other holder of Securities, or to obtain
or seek to obtain priority over or preference to any other such holder, or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all holders of Securities.

         Notwithstanding any other provisions in this Indenture, however, the
right of any holder of any Security to receive payment of the principal of (and
premium, if any) and interest on (including Compounded Interest and Additional
Sums, if any) and Liquidated Damages, if any, on such Security, on or after the
same shall have become due and payable, or to institute suit for the enforcement
of any such payment, shall not be impaired or affected without the consent of
such holder, and by accepting a Security hereunder it is expressly understood,
intended and covenanted by the taker and holder of every Security with every
other such taker and holder and the Debenture Trustee, that no one or more
holders of Securities shall have any right in any manner whatsoever by virtue or
by availing itself of any provision of this Indenture to affect, disturb or
prejudice the rights of the holders of any other Securities, or to obtain or
seek to obtain priority over or preference to any other such holder, or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all holders of Securities. For the
protection and enforcement of the provisions of this Section, each and every
Securityholder and the Debenture Trustee shall be entitled to such relief as can
be given either at law or in equity.

         The Corporation and the Debenture Trustee acknowledge that pursuant to
the Declaration, the holders of Capital Securities are entitled, in the
circumstances and subject to the limitations set forth therein, to commence a
Direct Action with respect to any Event of Default referred to in clause (a) or
(b) of Section 5.01.

         SECTION 5.05 PROCEEDINGS BY DEBENTURE TRUSTEE.

         In case an Event of Default occurs with respect to Securities and is
continuing, the Debenture Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Debenture Trustee shall deem most effectual to protect and
enforce any of such rights, either by suit in equity or by action at law or by
proceeding in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Debenture Trustee by this Indenture or by law.

         SECTION 5.06 REMEDIES CUMULATIVE AND CONTINUING.

         All powers and remedies given by this Article V to the Debenture
Trustee or to the Securityholders shall, to the extent permitted by law, be
deemed cumulative and not exclusive of any other powers and remedies available
to the Debenture Trustee or the holders of the Securities, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture or otherwise established
with respect to the Securities, and no delay or omission of the Debenture
Trustee or of any holder of any of the Securities to exercise any right or power
accruing upon any Event of Default occurring and continuing as aforesaid shall
impair any such right or power, or shall be construed to be a waiver of any such
default or an acquiescence therein; and, subject to the provisions of Section
5.04, every power and remedy given



                                      -30-
<PAGE>   37

by this Article V or by law to the Debenture Trustee or to the Securityholders
may be exercised from time to time, and as often as shall be deemed expedient,
by the Debenture Trustee or by the Securityholders.

         SECTION 5.07 DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY
MAJORITY OF SECURITYHOLDERS.

         The holders of a majority in aggregate principal amount of the
Securities at the time outstanding shall have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee; PROVIDED, HOWEVER, that (subject to the provisions of Section 6.01) the
Debenture Trustee shall have the right to decline to follow any such direction
if the Debenture Trustee shall determine that the action so directed would be
unjustly prejudicial to the holders not taking part in such direction or if the
Debenture Trustee being advised by counsel determines that the action or
proceeding so directed may not lawfully be taken or if the Debenture Trustee in
good faith by one of its Responsible Officers shall determine that the action or
proceedings so directed would involve the Debenture Trustee in personal
liability. Prior to any declaration accelerating the maturity of the Securities,
the holders of a majority in aggregate principal amount of the Securities at the
time outstanding may on behalf of the holders of all of the Securities waive any
past Default or Event of Default and its consequences except a Default (a) in
the payment of principal of (or premium, if any) or interest on (including
Compounded Interest and Additional Sums, if any) or Liquidated Damages, if any,
on any of the Securities (unless such default has been cured and a sum
sufficient to pay all matured installments of interest (including Compounded
Interest and Additional Sums, if any) and premium, if any, and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee) or
(b) in respect of covenants or provisions hereof which cannot be modified or
amended without the consent of the holder of each Security affected; PROVIDED,
HOWEVER, that if the Securities are held by the Property Trustee, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in aggregate liquidation amount of Trust Securities shall have
consented to such waiver or modification to such waiver; PROVIDED, FURTHER, that
if the consent of the holder of each outstanding Security is required, such
waiver shall not be effective until each holder of the Trust Securities shall
have consented to such waiver. Upon any such waiver, the Default covered thereby
shall be deemed to be cured for all purposes of this Indenture and the
Corporation, the Debenture Trustee and the holders of the Securities shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon. Whenever any Default or Event of Default hereunder shall
have been waived as permitted by this Section 5.07, said Default or Event of
Default shall for all purposes of the Securities and this Indenture be deemed to
have been cured and to be not continuing.

         SECTION 5.08  NOTICE OF DEFAULTS

         (a) The Debenture Trustee shall, within 90 days after the occurrence of
a Default with respect to the Securities actually known to a Responsible Officer
of the Debenture Trustee, mail to all Securityholders, as the names and
addresses of such holders appear upon the Security Register, notice of all such
Defaults, unless such Default shall have been cured before the giving of such
notice (the term "Default" for the purpose of this Section 5.08 being hereby
defined to be any of the events specified in clauses (a), (b), (c), (d) and (e)
of Section 5.01, not including periods of grace,



                                      -31-
<PAGE>   38

if any, provided for therein, and irrespective of the giving of written notice
specified in clause (c) of Section 5.01); PROVIDED, HOWEVER, that, except in the
case of Default in the payment of the principal of (or premium, if any) or
interest (including Compounded Interest or Additional Sums, if any) or
Liquidated Damages, if any, on any of the Securities, the Debenture Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee, or a trust committee of directors and/or
Responsible Officers of the Debenture Trustee in good faith determines that the
withholding of such notice is in the interests of the Securityholders; PROVIDED,
FURTHER, that in the case of any Default of the character specified in Section
5.01(c), no such notice to Securityholders shall be given until at least 60 days
after the occurrence thereof, but shall be given within 90 days after such
occurrence.

         (b) Within ten Business Days after the occurrence of any Event of
Default actually known to a Responsible Officer of the Debenture Trustee, the
Debenture Trustee shall transmit notice of such Event of Default to all
Securityholders as their names and addresses appear on the Security Register,
unless such Event of Default shall have been cured or waived.

         SECTION 5.09 UNDERTAKING TO PAY COSTS.

         All parties to this Indenture agree, and each holder of any Security by
its acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Debenture Trustee for any action
taken or omitted by it as Debenture Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 5.09 shall not apply to any suit instituted
by the Debenture Trustee, to any suit instituted by any Securityholder, or group
of Securityholders, holding in the aggregate more than 10% in aggregate
principal amount of the Securities outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest (including Compounded Interest and Additional Sums,
if any) or Liquidated Damages, if any, on any Security against the Corporation
on or after the same shall have become due and payable.


                                   ARTICLE VI
                        CONCERNING THE DEBENTURE TRUSTEE

         SECTION 6.01 DUTIES AND RESPONSIBILITIES OF DEBENTURE TRUSTEE.

         With respect to the holders of the Securities issued hereunder, the
Debenture Trustee, prior to the occurrence of an Event of Default (which, other
than in the case of Sections 5.01(a) and 5.01(b) hereof, is known to the
Debenture Trustee) and after the curing or waiving of all such Events of Default
which may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Indenture. In case an Event of Default
(which, other than in the case of Sections 5.01(a) and 5.01(b) hereof, is known
to the Debenture Trustee) has occurred (which has not been cured or waived), the
Debenture Trustee shall exercise such of the rights and powers vested in



                                      -32-
<PAGE>   39

it by this Indenture, and use the same degree of care and skill in their
exercise as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

         No provision of this Indenture shall be construed to relieve the
Debenture Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that:

         (a)      prior to the occurrence of an Event of Default (which, other
                  than in the case of Sections 5.01(a) and 5.01(b) hereof, is
                  known to the Debenture Trustee) and after the curing or
                  waiving of all such Events of Default which may have occurred,

                  (1)      the duties and obligations of the Debenture Trustee
                           shall be determined solely by the express provisions
                           of this Indenture, and the Debenture Trustee shall
                           not be liable except for the performance of such
                           duties and obligations as are specifically set forth
                           in this Indenture, and no implied covenants or
                           obligations shall be read into this Indenture against
                           the Debenture Trustee; and

                  (2)      in the absence of bad faith on the part of the
                           Debenture Trustee, the Debenture Trustee may
                           conclusively rely, as to the truth of the statements
                           and the correctness of the opinions expressed
                           therein, upon any certificate or opinion furnished to
                           the Debenture Trustee and conforming to the
                           requirements of this Indenture; but, in the case of
                           any such certificate or opinion which by any
                           provision hereof are specifically required to be
                           furnished to the Debenture Trustee, the Debenture
                           Trustee shall be under a duty to examine the same to
                           determine whether or not it conforms on its face to
                           the requirements of this Indenture;

                  (b)      the Debenture Trustee shall not be liable for any
                           error of judgment made in good faith by a Responsible
                           Officer or Responsible Officers, unless it shall be
                           proved that the Debenture Trustee was negligent in
                           ascertaining the pertinent facts; and

                  (c)      the Debenture Trustee shall not be liable with
                           respect to any action taken or omitted to be taken by
                           it in good faith in accordance with the direction of
                           the Securityholders pursuant to Section 5.07,
                           relating to the time, method and place of conducting
                           any proceeding for any remedy available to the
                           Debenture Trustee, or exercising any trust or power
                           conferred upon the Debenture Trustee, under this
                           Indenture.

         None of the provisions contained in this Indenture shall require the
Debenture Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if it reasonably believes that the repayment of
such funds or liability is not reasonably assured to it under the terms of this
Indenture or adequate indemnity against such risk is not reasonably assured to
it.

         SECTION 6.02 RELIANCE ON DOCUMENTS, OPINIONS, ETC.

         Except as otherwise provided in Section 6.01:

         (a)      the Debenture Trustee may conclusively rely and shall be
                  protected in acting or refraining from acting upon any
                  resolution, certificate, statement, instrument, opinion,
                  report, notice, request, consent, order, bond, note, debenture
                  or other paper or document believed by it to be genuine and to
                  have been signed or presented by the proper party or parties;

         (b)      any request, direction, order or demand of the Corporation
                  mentioned herein may be sufficiently evidenced by an Officers'
                  Certificate (unless other evidence in respect thereof be
                  herein specifically prescribed); and any Board Resolution may
                  be evidenced to the Debenture Trustee by a copy thereof
                  certified by the Secretary or an Assistant Secretary of the
                  Corporation;

         (c)      the Debenture Trustee may consult with counsel of its
                  selection and any advice or Opinion of Counsel shall be full
                  and complete authorization and protection in respect of any
                  action taken or suffered or omitted by it hereunder in good
                  faith and in accordance with such advice or Opinion of
                  Counsel;

         (d)      the Debenture Trustee shall be under no obligation to exercise
                  any of the rights or powers vested in it by this Indenture at
                  the request, order or direction of any of the Securityholders,
                  pursuant to the provisions of this Indenture, unless such
                  Securityholders shall have offered to the Debenture Trustee
                  reasonable and sufficient security or indemnity against the
                  costs, expenses and liabilities which may be incurred therein
                  or thereby;

         (e)      the Debenture Trustee shall not be liable for any action taken
                  or omitted by it in good faith and believed by it to be
                  authorized or within the discretion or rights or powers
                  conferred upon it by this Indenture; nothing contained herein
                  shall, however, relieve the Debenture Trustee of the
                  obligation, upon the occurrence of an Event of Default (which,
                  other than in the case of Sections 5.01(a) and 5.01(b) hereof,
                  is known to the Debenture Trustee) (that has not been cured or
                  waived), to exercise such of the rights and powers vested in
                  it by this Indenture, and to use the same degree of care and
                  skill in its exercise as a prudent person would exercise or
                  use under the circumstances in the conduct of his or her own
                  affairs;

         (f)      the Debenture Trustee shall not be bound to make any
                  investigation into the facts or matters stated in any
                  resolution, certificate, statement, instrument, opinion,
                  report, notice, request, consent, order, approval, bond,
                  debenture, coupon or other paper or document, unless requested
                  in writing to do so by the holders of a majority in aggregate
                  principal amount of the outstanding Securities; PROVIDED,
                  HOWEVER, that if the payment within a reasonable time to the
                  Debenture Trustee of the costs, expenses or liabilities likely
                  to be incurred by it in the making of such investigation is,
                  in the opinion of the Debenture Trustee, not reasonably
                  assured to the Debenture Trustee

                  by the security afforded to it by the terms of this Indenture,
                  the Debenture Trustee may require reasonable indemnity against
                  such expense or liability as a condition to so proceeding;

         (g)      the Debenture Trustee may execute any of the trusts or powers
                  hereunder or perform any duties hereunder either directly or
                  by or through agents (including any Authenticating Agent) or
                  attorneys, and the Debenture Trustee shall not be responsible
                  for any misconduct or negligence on the part of any such agent
                  or attorney appointed by it with due care;

         (h)      the Debenture Trustee shall not be charged with knowledge of
                  any Default or Event of Default unless (1) such Default or
                  Event of Default falls within Section 5.01(a) (other than a
                  default with respect to the payment of Compounded Interest,
                  Liquidated Damages or Additional Sums) or Section 5.01(b) of
                  the Indenture, (2) a Responsible Officer shall have actual
                  knowledge of such Default or Event of Default or (3) written
                  notice of such Default or Event of Default shall have been
                  given to the Debenture Trustee by the Corporation or any other
                  obligor on the Securities or by any holder of the Securities;
                  and

         (i)      the Debenture Trustee shall not be liable for any action
                  taken, suffered or omitted by it in good faith, without
                  negligence or willful misconduct and believed by it to be
                  authorized or within the discretion or rights or powers
                  conferred upon it by this Indenture.

         SECTION 6.03 NO RESPONSIBILITY FOR RECITALS, ETC.

         The recitals contained herein and in the Securities (except in the
certificate of authentication of the Debenture Trustee or the Authenticating
Agent) shall be taken as the statements of the Corporation, and the Debenture
Trustee and the Authenticating Agent assume no responsibility for the
correctness of the same. The Debenture Trustee and the Authenticating Agent make
no representations as to the validity or sufficiency of this Indenture or of the
Securities. The Debenture Trustee and the Authenticating Agent shall not be
accountable for the use or application by the Corporation of any Securities or
the proceeds of any Securities authenticated and delivered by the Debenture
Trustee or the Authenticating Agent in conformity with the provisions of this
Indenture.

         SECTION 6.04 DEBENTURE TRUSTEE, AUTHENTICATING AGENT, PAYING AGENTS,
TRANSFER AGENTS AND REGISTRAR MAY OWN SECURITIES.

         The Debenture Trustee or any Authenticating Agent or any paying agent
or any transfer agent or any security registrar for the Securities, in its
individual or any other capacity, may become the owner or pledgee of Securities
with the same rights it would have if it were not Debenture Trustee,
Authenticating Agent, paying agent, transfer agent or security registrar for the
Securities.

         SECTION 6.05 MONEYS TO BE HELD IN TRUST.

         Subject to the provisions of Section 11.04, all moneys received by the
Debenture Trustee or any paying agent shall, until used or applied as herein
provided, be held in trust for the purpose for which they were received, but
need not be segregated from other funds except to the extent required by law.
The Debenture Trustee and any paying agent shall be under no liability for
interest on any money received by it hereunder except as otherwise agreed in
writing with the Corporation. So long as no Event of Default shall have occurred
and be continuing, all interest allowed on any such moneys shall be paid from
time to time upon the written order of the Corporation, signed by an Officer
thereof.

         SECTION 6.06 COMPENSATION AND EXPENSES OF DEBENTURE TRUSTEE.

         The Corporation, as issuer of Securities under this Indenture,
covenants and agrees to pay to the Debenture Trustee from time to time, and the
Debenture Trustee shall be entitled to, such compensation as shall be agreed to
in writing between the Corporation and the Debenture Trustee (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust), and the Corporation will pay or reimburse the Debenture Trustee
upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Debenture Trustee in accordance with any of the
provisions of this Indenture (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ), except any such expense, disbursement or advance as may arise from
its negligence or bad faith. The Corporation also covenants to indemnify each of
the Debenture Trustee (including in its individual capacity) and any predecessor
Debenture Trustee (and its officers, agents, directors and employees) for, and
to hold it harmless against, any and all loss, damage, claim, action, suit,
liability or expense including taxes (other than taxes based on the income of
the Debenture Trustee) incurred without negligence or bad faith on the part of
the Debenture Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim of liability. The obligations of the Corporation under
this Section 6.06 to compensate and indemnify the Debenture Trustee and to pay
or reimburse the Debenture Trustee for expenses, disbursements and advances
shall constitute additional indebtedness hereunder. Such additional indebtedness
shall be secured by a lien prior to that of the Securities upon all property and
funds held or collected by the Debenture Trustee as such, except funds held in
trust for the benefit of the holders of particular Securities.

         When the Debenture Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(d) or Section
5.01(e), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for its services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

         The provisions of this Section shall survive the resignation or removal
of the Debenture Trustee and the defeasance or other termination of this
Indenture.

         SECTION 6.07 OFFICERS' CERTIFICATE AS EVIDENCE.

         Except as otherwise provided in Sections 6.01 and 6.02, whenever in the
administration of the provisions of this Indenture the Debenture Trustee shall
deem it necessary or desirable that a matter be proved or established prior to
taking or omitting any action hereunder, such matter (unless other evidence in
respect thereof is herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Debenture Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Debenture Trustee, and such Officers' Certificate, in the absence of negligence
or bad faith on the part of the Debenture Trustee, shall be full warrant to the
Debenture Trustee for any action taken or omitted by it under the provisions of
this Indenture upon the faith thereof.

         SECTION 6.08  CONFLICTING INTEREST OF DEBENTURE TRUSTEE.

         If the Debenture Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Debenture Trustee and the Corporation shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 6.09 ELIGIBILITY OF DEBENTURE TRUSTEE.

         The Debenture Trustee hereunder shall at all times be a Person
organized and doing business under the laws of the United States of America or
any state or territory thereof or of the District of Columbia, or a corporation
or other Person permitted to act as trustee by the Commission authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least fifty million U.S. dollars ($50,000,000) and subject to
supervision or examination by federal, state, territorial, or District of
Columbia authority. If such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section 6.09 the combined
capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published.

         The Corporation may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Corporation, serve
as Debenture Trustee.

         In case at any time the Debenture Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, the Debenture Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

         SECTION 6.10 RESIGNATION OR REMOVAL OF DEBENTURE TRUSTEE.

         (a) The Debenture Trustee, or any trustee or trustees hereafter
appointed, may at any time resign by giving written notice of such resignation
to the Corporation and by mailing notice thereof to the holders of the
Securities at their addresses as they shall appear on the Security Register.
Upon receiving such notice of resignation, the Corporation shall promptly
appoint a successor trustee or trustees by written instrument, in duplicate, one
copy of which instrument shall be delivered to the resigning Debenture Trustee
and one copy to the successor trustee. If no successor trustee shall have


                                      -37-
<PAGE>   44

been so appointed and have accepted appointment within 60 days after the mailing
of such notice of resignation to the affected Securityholders, the resigning
Debenture Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee, or any Securityholder who has been a bona
fide holder of a Security for at least six months may, subject to the provisions
of Section 5.09, on behalf of himself and all others similarly situated,
petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

         (b)      In case at any time any of the following shall occur:

                  (1)      the Debenture Trustee shall fail to comply with the
                           provisions of Section 6.08 after written request
                           therefor by the Corporation or by any Securityholder
                           who has been a bona fide holder of a Security or
                           Securities for at least six months, or

                  (2)      the Debenture Trustee shall cease to be eligible in
                           accordance with the provisions of Section 6.09 and
                           shall fail to resign after written request therefor
                           by the Corporation or by any such Securityholder, or

                  (3)      the Debenture Trustee shall become incapable of
                           acting, or shall be adjudged a bankrupt or insolvent,
                           or a receiver of the Debenture Trustee or of its
                           property shall be appointed, or any public officer
                           shall take charge or control of the Debenture Trustee
                           or of its property or affairs for the purpose of
                           rehabilitation, conservation or liquidation,

then, in any such case, the Corporation may remove the Debenture Trustee and
appoint a successor trustee by written instrument, in duplicate, one copy of
which instrument shall be delivered to the Debenture Trustee so removed and one
copy to the successor trustee, or, subject to the provisions of Section 5.09,
any Securityholder who has been a bona fide holder of a Security for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the removal of the Debenture Trustee and
the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Debenture
Trustee and appoint a successor trustee.

         (c) The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Debenture Trustee
and nominate a successor trustee, which shall be deemed appointed as successor
trustee unless within 10 days after written notification of such nomination the
Corporation objects thereto, or if no successor trustee shall have been so
appointed and shall have accepted appointment within 30 days after such removal,
in which case the Debenture Trustee so removed or any Securityholder, upon the
terms and conditions and otherwise as in subsection (a) of this Section 6.10
provided, may petition any court of competent jurisdiction for an appointment of
a successor trustee.

         (d) Any resignation or removal of the Debenture Trustee and appointment
of a successor trustee pursuant to any of the provisions of this Section 6.10
shall become effective upon acceptance of appointment by the successor trustee
as provided in Section 6.11.

         SECTION 6.11  ACCEPTANCE BY SUCCESSOR DEBENTURE TRUSTEE.

         Any successor trustee appointed as provided in Section 6.10 shall
execute, acknowledge and deliver to the Corporation and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the retiring trustee shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Corporation or of the successor
trustee, the trustee ceasing to act shall, upon payment of all amounts then due
it pursuant to the provisions of Section 6.06, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee
so ceasing to act and shall duly assign, transfer and deliver to such successor
trustee all property and money held by such retiring trustee thereunder. Upon
request of any such successor trustee, the Corporation shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.06.

         No successor trustee shall accept appointment as provided in this
Section 6.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 6.08 and eligible under the
provisions of Section 6.09.


         Upon acceptance of appointment by a successor trustee as provided in
this Section 6.11, the Corporation shall mail notice of the succession of such
trustee hereunder to the holders of Securities at their addresses as they shall
appear on the Security Register. If the Corporation fails to mail such notice
within 10 days after the acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the
Corporation.

         SECTION 6.12 SUCCESSION BY MERGER, ETC.

         Any Person into which the Debenture Trustee may be merged or with which
it may be consolidated, or any Person resulting from any merger or consolidation
to which the Debenture Trustee shall be a party, or any Person succeeding to all
or substantially all of the corporate trust business of the Debenture Trustee,
shall be the successor of the Debenture Trustee hereunder without the execution
or filing of any paper or any further act on the part of any of the parties
hereto.

         In case any Securities shall have been authenticated but not delivered
at the time such successor to the Debenture Trustee shall succeed to the trusts
created by this Indenture, any such successor to the Debenture Trustee may adopt
the certificate of authentication of any predecessor trustee, and deliver such
Securities so authenticated; and in case at that time any of the Securities
shall not have been authenticated, any successor to the Debenture Trustee may
authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor trustee; and in all such cases such certificates
shall have the full force which the Securities or this Indenture elsewhere
provides that the certificate of the Debenture Trustee shall have; PROVIDED,
HOWEVER, that the right to adopt the certificate of authentication of any
predecessor Debenture Trustee or



                                      -39-
<PAGE>   46

authenticate Securities in the name of any predecessor Debenture Trustee shall
apply only to its successor or successors by merger or consolidation.

         SECTION 6.13 LIMITATION ON RIGHTS OF DEBENTURE TRUSTEE AS A CREDITOR.

         The Debenture Trustee shall comply with Section 311(a) of the Trust
Indenture Act, excluding any creditor relationship described in Section 311(b)
of the Trust Indenture Act. A Debenture Trustee who has resigned or been removed
shall be subject to Section 311(a) of the Trust Indenture Act to the extent
included therein.

         SECTION 6.14 AUTHENTICATING AGENTS.

         There may be one or more Authenticating Agents appointed by the
Debenture Trustee upon the request of the Corporation with power to act on its
behalf and subject to its direction in the authentication and delivery of
Securities issued upon exchange or transfer thereof as fully to all intents and
purposes as though any such Authenticating Agent had been expressly authorized
to authenticate and deliver Securities; PROVIDED, HOWEVER, that the Debenture
Trustee shall have no liability to the Corporation for any acts or omissions of
the Authenticating Agent with respect to the authentication and delivery of
Securities. Any such Authenticating Agent shall at all times be a Person
organized and doing business under the laws of the United States or of any state
or territory thereof or of the District of Columbia authorized under such laws
to act as Authenticating Agent, having a combined capital and surplus of at
least $5,000,000 and being subject to supervision or examination by federal,
state, territorial or District of Columbia authority. If such Person publishes
reports of condition at least annually pursuant to law or the requirements of
such authority, then for the purposes of this Section 6.14 the combined capital
and surplus of such Person shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect herein specified in this Section.

         Any Person into which any Authenticating Agent may be merged or with
which it may be consolidated, or any Person resulting from any merger or
consolidation to which any Authenticating Agent shall be a party, or any Person
succeeding to the corporate trust business of any Authenticating Agent, shall be
the successor of such Authenticating Agent hereunder, if such successor Person
is otherwise eligible under this Section 6.14 without the execution or filing of
any paper or any further act on the part of the parties hereto or such
Authenticating Agent.

         Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Debenture Trustee and to the Corporation. The
Debenture Trustee may at any time terminate the agency of any Authenticating
Agent by giving written notice of termination to such Authenticating Agent and
to the Corporation. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible under this Section 6.14, the Debenture Trustee may, and upon the
request of the Corporation shall, promptly appoint a successor Authenticating
Agent eligible under this Section 6.14, shall give written notice of such
appointment to the Corporation and shall mail notice of such appointment to all
Securityholders as the names and addresses of such holders appear on the
Security Register. Any



                                      -40-
<PAGE>   47

successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent herein.

         The Corporation, as issuer of the Securities, agrees to pay to any
Authenticating Agent from time to time reasonable compensation for its services.
Any Authenticating Agent shall have no responsibility or liability for any
action taken by it as such in accordance with the directions of the Debenture
Trustee.


                                   ARTICLE VII
                         CONCERNING THE SECURITYHOLDERS

         SECTION 7.01 ACTION BY SECURITYHOLDERS.

         Whenever in this Indenture it is provided that the holders of a
specified percentage in aggregate principal amount of the Securities may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action), the fact that at
the time of taking any such action the holders of such specified percentage have
joined therein may be evidenced (a) by any instrument (including by way of
electronic transmission) or any number of instruments of similar tenor executed
by such Securityholders in person or by agent or proxy appointed in writing, or
(b) by the record of such holders of Securities voting in favor thereof at any
meeting of such Securityholders duly called and held in accordance with the
provisions of Article VIII, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of such Securityholders.

         If the Corporation shall solicit from the Securityholders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Corporation may, at its option, as evidenced by an Officers' Certificate, fix in
advance a record date for the determination of Securityholders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other
action, but the Corporation shall have no obligation to do so. If such a record
date is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other action may be given before or after the record date, but only
the Securityholders of record at the close of business on the record date shall
be deemed to be Securityholders for the purposes of determining whether
Securityholders of the requisite proportion of outstanding Securities have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other action, and for that purpose the
outstanding Securities shall be computed as of the record date; PROVIDED,
HOWEVER, that no such authorization, agreement or consent by such
Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

         SECTION 7.02 PROOF OF EXECUTION BY SECURITYHOLDERS.

         Subject to the provisions of Sections 6.01, 6.02 and 8.05, proof of the
execution of any instrument by a Securityholder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Debenture Trustee or in such



                                      -41-
<PAGE>   48

manner as shall be satisfactory to the Debenture Trustee. The ownership of
Securities shall be proved by the Security Register or by a certificate of the
security registrar for the Securities. The Debenture Trustee may require such
additional proof of any matter referred to in this Section 7.02 as it shall deem
necessary.

         The record of any Securityholders' meeting shall be proved in the
manner provided in Section 8.06.

         SECTION 7.03  WHO ARE DEEMED ABSOLUTE OWNERS.

         Prior to due presentment for registration of transfer of any Security,
the Corporation, the Debenture Trustee, any Authenticating Agent, any paying
agent, any transfer agent and any security registrar for the Securities may deem
the person in whose name such Security shall be registered upon the Security
Register to be, and may treat him as, the absolute owner of such Security
(whether or not such Security shall be overdue) for the purpose of receiving
payment of or on account of the principal of and premium, if any, and (subject
to Section 2.06) interest on such Security and for all other purposes; and
neither the Corporation nor the Debenture Trustee nor any Authenticating Agent
nor any paying agent nor any transfer agent nor any security registrar for the
Securities shall be affected by any notice to the contrary. All such payments so
made to any holder for the time being or upon his order shall be valid and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

         SECTION 7.04  SECURITIES OWNED BY CORPORATION DEEMED NOT OUTSTANDING.

         In determining whether the holders of the requisite aggregate principal
amount of Securities have concurred in any direction, consent or waiver under
this Indenture, Securities that are owned by the Corporation or any other
obligor on the Securities or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Corporation or
any other obligor on the Securities shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; PROVIDED, HOWEVER, that
for the purposes of determining whether the Debenture Trustee shall be protected
in relying on any such direction, consent or waiver, only Securities which a
Responsible Officer of the Debenture Trustee actually knows are so owned shall
be so disregarded. Securities so owned which have been pledged in good faith may
be regarded as outstanding for the purposes of this Section 7.04 if the pledgee
shall establish to the satisfaction of the Debenture Trustee the pledgee's right
to vote such Securities and that the pledgee is not the Corporation or any such
other obligor or Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Corporation or any such other
obligor. In the case of a dispute as to such right, any decision by the
Debenture Trustee taken upon the advice of counsel shall be full protection to
the Debenture Trustee.

         SECTION 7.05  REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND.

         At any time prior to (but not after) the evidencing to the Debenture
Trustee, as provided in Section 7.01, of the taking of any action by the holders
of the percentage in aggregate principal amount of the Securities specified in
this Indenture in connection with such action, any holder of a Security (or any
Security issued in whole or in part in exchange or substitution therefor),
subject to



                                      -42-
<PAGE>   49

Section 7.01, the serial number of which is shown by the evidence to be included
in the group of Securities the holders of which have consented to such action,
may, by filing written notice with the Debenture Trustee at its principal office
and upon proof of holding as provided in Section 7.02, revoke such action so far
as concerns such Security (or so far as concerns the principal amount
represented by any exchanged or substituted Security). Except as aforesaid, any
such action taken by the holder of any Security shall be conclusive and binding
upon such holder and upon all future holders and owners of such Security, and of
any Security issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Security or any
Security issued in exchange or substitution therefor.


                                  ARTICLE VIII

                  Trustee, or to give any directions to the Debenture Trustee,
                  or to consent to the waiving of any Default hereunder and its
                  consequences, or to take any other action authorized to be
                  taken by Securityholders pursuant to any of the provisions of
                  Article V;

         (b)      to remove the Debenture Trustee and nominate a successor
                  trustee pursuant to the provisions of Article VI;

         (c)      to consent to the execution of an indenture or indentures
                  supplemental hereto pursuant to the provisions of Section
                  9.02; or

         (d)      to take any other action authorized to be taken by or on
                  behalf of the holders of any specified aggregate principal
                  amount of such Securities under any other provision of this
                  Indenture or under applicable law.

         SECTION 8.02 CALL OF MEETINGS BY DEBENTURE TRUSTEE.

         The Debenture Trustee may at any time call a meeting of Securityholders
to take any action specified in Section 8.01, to be held at such time and at

<PAGE>   50

         SECTION 8.03 CALL OF MEETINGS BY CORPORATION OR SECURITYHOLDERS.

         In case at any time the Corporation, pursuant to a resolution of the
Board of Directors, or the holders of at least 20% in aggregate principal amount
of the Securities then outstanding, shall have requested the Debenture Trustee
to call a meeting of Securityholders, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Debenture Trustee shall not have mailed the notice of such meeting within 20
days after receipt of such request, then the Corporation or such Securityholders
may determine the time and the place in Columbus, Ohio for such meeting and may
call such meeting to take any action authorized in Section 8.01, by mailing
notice thereof as provided in Section 8.02.

         SECTION 8.04 QUALIFICATIONS FOR VOTING.

         To be entitled to vote at any meeting of Securityholders, a Person

Securityholders shall be the Persons entitled to vote at such meeting and their
counsel and any representatives of the Debenture Trustee and its counsel and any
representatives of the Corporation and its counsel.

         SECTION 8.05  REGULATIONS.

                  the Securityholders, and to make the occurrence, or the
                  occurrence and continuance, of a default in any of such

                  enforcement upon such default or may limit the remedies
                  available to the Debenture Trustee upon such default;

                  Securities with the Securities issued hereunder in fully
                  registered form and to make all appropriate changes for such
                  purpose;

         (d)      to cure any ambiguity or to correct or supplement any
                  provision contained herein or in any supplemental indenture
                  which may be defective or inconsistent with any other
                  provision contained herein or in any supplemental indenture;
                  or to make such other provisions in regard to matters or
                  questions arising under this Indenture, provided that any such
                  action shall not materially adversely affect the interests of
                  the holders of the Securities;

         (e)      to evidence and provide for the acceptance of appointment
                  hereunder by a successor trustee with respect to the

                  necessary, desirable or appropriate in connection with the
                  issuance of Securities to holders of Capital Securities in the
                  event of a distribution of Securities by the Trust following a
                  Dissolution Event, provided that any such action shall not
                  materially adversely affect the interests of the holders of
                  the Securities;

         (g)      to qualify or maintain qualification of this Indenture under

                  of any Securityholder in any material respect.

         The Debenture Trustee is hereby authorized to join with the Corporation
in the execution of any supplemental indenture to effect such amendment, to make
any further appropriate agreements and stipulations which may be therein
contained and to accept the conveyance, transfer and assignment of any property
thereunder, but the Debenture Trustee shall not be obligated to, but may in its
discretion, enter into any such supplemental indenture which affects the
Debenture Trustee's own rights, duties or immunities under this Indenture or
otherwise.

         Any amendment to this Indenture authorized by the provisions of this
Section 9.01 may be executed by the Corporation and the Debenture Trustee
without the consent of the holders of any of the Securities at the time
outstanding, notwithstanding any of the provisions of Section 9.02.

         With the consent (evidenced as provided in Section 7.01) of the holders
of a majority in aggregate principal amount of the Securities at the time
outstanding, the Corporation, when authorized by a Board Resolution, and the
Debenture Trustee may from time to time and at any time amend this Indenture for
the purpose of adding any provisions to or changing in any manner or


                                      -46-
<PAGE>   53

eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the holders of the Securities; PROVIDED, HOWEVER, that no
such amendment shall, without the consent of the holders of each Security then
outstanding and affected thereby (i) change the Maturity Date of any Security,
or reduce the rate or extend the time of payment of interest thereon (except as
contemplated by Article XVI), or reduce the principal amount thereof, or change
any prepayment provisions, or make the principal thereof or any interest or
premium thereon payable in any coin or currency other than U.S. dollars, or
impair or affect the right of any Securityholder to institute suit for payment
thereof, or (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to consent to any such amendment to the Indenture; PROVIDED,
HOWEVER, that if the Securities are held by the Trust, such amendment shall not
be effective until the holders of a majority in liquidation amount of Trust
Securities shall have consented to such amendment; PROVIDED, FURTHER, that if
the consent of the holder of each outstanding Security is required, such
amendment shall not be effective until each holder of the Trust Securities shall
have consented to such amendment.

         Upon the request of the Corporation accompanied by a copy of a
resolution of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture effecting such
amendment, and upon the filing with the Debenture Trustee of evidence of the
consent of Securityholders as aforesaid, the Debenture Trustee shall join with
the Corporation in the execution of such supplemental indenture unless such
supplemental indenture affects the Debenture Trustee's own rights, duties or
immunities under this Indenture or otherwise, in which case the Debenture
Trustee may in its discretion, but shall not be obligated to, enter into such
supplemental indenture.

         Promptly after the execution by the Corporation and the Debenture
Trustee of any supplemental indenture pursuant to the provisions of this
Section, the Debenture Trustee shall transmit by mail, first class postage
prepaid, a notice, prepared by the Corporation, setting forth in general terms
the substance of such supplemental indenture, to the Securityholders as their
names and addresses appear upon the Security Register. Any failure of the
Debenture Trustee to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

         It shall not be necessary for the consent of the Securityholders under
this Section 9.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

         SECTION 9.03 COMPLIANCE WITH TRUST INDENTURE ACT; EFFECT OF
SUPPLEMENTAL INDENTURES.

         Any supplemental indenture executed pursuant to the provisions of this
Article IX shall comply with the Trust Indenture Act. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article IX, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Debenture Trustee, the Corporation
and the holders of Securities shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

Indenture contained in any such supplemental indenture may be prepared and

         SECTION 10.01  CORPORATION MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

         Nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of the Corporation with or into any other
Person (whether or not affiliated with the Corporation, as the case may be), or
successive consolidations or mergers in which the Corporation or its successor
or successors, as the case may be, shall be a party or parties, or shall prevent

lease of property is made is a Person organized and existing under the laws of
the United States or any State thereof or the District of Columbia, and (b) if

delivered to the Debenture Trustee by the Person formed by such consolidation,
or into which the Corporation shall have been merged, or by the Person which
shall have acquired such property, as the case may be, and (c) after giving
effect to such consolidation, merger, sale, conveyance, transfer or lease, no
Default or Event of Default shall have occurred and be continuing.

         SECTION 10.02 SUCCESSOR PERSON TO BE SUBSTITUTED FOR CORPORATION.

         In case of any such consolidation, merger, sale, conveyance, transfer

Corporation thereupon shall be relieved of any further liability or obligation
hereunder or upon the Securities. Such successor Person thereupon may cause to

as though all of such Securities had been issued at the date of the execution
hereof.

         SECTION 10.03 OPINION OF COUNSEL TO BE GIVEN DEBENTURE TRUSTEE.

the Securities not theretofore canceled or delivered to the Debenture Trustee
for cancellation shall have become due and payable, or are by their terms to
become due and payable within one year or are to be called for prepayment within
one year under arrangements satisfactory to the Debenture Trustee for the giving

interest (including Compounded Interest and Additional Sums, if any) or
Liquidated Damages, if any, on the Securities (1) theretofore repaid to the
Corporation in accordance with the provisions of Section 11.04, or (2) paid to
any State or to the District of Columbia pursuant to its unclaimed property or
similar laws, and if, in either case the Corporation shall also pay or cause to
be paid all other sums payable hereunder by the Corporation, then this Indenture

accompanied by any Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Corporation, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Corporation,
however, hereby agrees to reimburse the Debenture Trustee for any costs or

and interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the holders of outstanding Securities.

         Upon the satisfaction and discharge of this Indenture all moneys then
held by any paying agent of the Securities (other than the Debenture Trustee)

                  irrevocably with the Debenture Trustee or the Defeasance Agent
                  (as defined below) as trust funds in trust, specifically

                  combination of (i) and (ii), sufficient, in the opinion (with

                  the same times as would have been the case if such option had
                  not been exercised.

and discharged the entire indebtedness represented by, and obligations under,
the Securities and to have satisfied all the obligations under this Indenture
relating to the Securities (and the Debenture Trustee, at the expense

         In any case where the date of payment of principal of (or premium, if
any) or interest on the Securities is not a Business Day, the payment of such

on such date but will be made on the next succeeding Business Day, except if
such Business Day is in the next succeeding calendar year, such payment will be

as if made on the original date of payment, and no interest shall accrue for the
period from and after such date.

         SECTION 13.08  TRUST INDENTURE ACT TO CONTROL.

         If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by Sections 310 to 318,

         SECTION 13.10 EXECUTION IN COUNTERPARTS.

         This Indenture may be executed in any number of counterparts, each of

         SECTION 13.11  SEPARABILITY.

         In case any one or more of the provisions contained in this Indenture
or in the Securities shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Indenture or of the Securities,
but this Indenture and the Securities shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.

         SECTION 13.12  ASSIGNMENT.

         The Corporation will have the right at all times to assign any of its
respective rights or obligations under this Indenture to a direct or indirect
wholly owned Subsidiary of the Corporation, provided that, in the event of any
such assignment, the Corporation will remain liable for all such obligations.
Subject to the foregoing, this Indenture is binding upon and inures to the
benefit of the parties thereto and their respective successors and assigns. This
Indenture may not otherwise be assigned by the parties thereto.

         SECTION 13.13 ACKNOWLEDGMENT OF RIGHTS.

         The Corporation acknowledges that, with respect to any Securities held
by the Trust or a trustee of such Trust, if the Property Trustee of such Trust
fails to enforce its rights under this Indenture as the holder of the Securities
held as the assets of the Trust, any holder of Capital Securities may institute
legal proceedings directly against the Corporation to enforce such Property
Trustee's rights under this Indenture without first instituting any legal
proceedings against such Property Trustee or any other person or entity.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Corporation to
pay principal of (or premium, if any) or interest on the Securities when due,
the Corporation acknowledges that a holder of Capital Securities may directly
institute a proceeding for enforcement of payment to such holder of the
principal of (or premium, if any) or interest on the Securities having an
aggregate principal amount equal to the aggregate liquidation amount of the
Capital Securities of such holder on or after the respective due date specified
in the Securities.

         SECTION 14.01  SPECIAL EVENT PREPAYMENT.

         If, prior to the Initial Optional Redemption Date, a Special Event has
occurred and is continuing, then notwithstanding Section 14.02(a) but subject to
Section 14.02(c), the Corporation shall have the right, at any time within 90
days following the occurrence of such Special Event, upon (i) not less than 45
days' written notice to the Debenture Trustee and (ii) not less than 30 days nor
more than 60 days' written notice to the Securityholders, to prepay the
Securities, in whole (but not in part), at the Special Event Prepayment Price.
Following a Special Event, the Corporation shall take such action as is
necessary to promptly determine the Special Event Prepayment Price, including,
without limitation, the appointment of a Quotation Agent. The Special Event
Prepayment

prepayment or such earlier time as the Corporation determines, provided that the
Corporation shall deposit with the Debenture Trustee an amount sufficient to pay
the Special Event Prepayment Price by 10:00 a.m., New York City time, on the
date such Special Event Prepayment Price is to be paid.

         SECTION 14.02 OPTIONAL PREPAYMENT BY CORPORATION.

         (a) Subject to Sections 14.02(b) and (c), the Corporation shall have
the right to prepay the Securities, in whole or in part, at any time on or after
the Initial Optional Redemption Date, upon (i) not more than 45 days' written
notice to the Debenture Trustee and (ii) not less than 30 days and not more than
60 days' written notice to the Securityholders, at the prepayment prices set
forth below plus, in each case, accrued and unpaid interest thereon (including
Compounded Interest and Additional Sums, if any) to the applicable date of
prepayment (the "Optional Prepayment Price"), if prepaid during the 12-month
period beginning October 15 of the years indicated below.


               YEAR                            PERCENTAGE OF PRINCIPAL

               2015                                    101.975%
               2016                                    101.481%

               2019 and thereafter                     100.000%

         If the Securities are only partially prepaid pursuant to this Section
14.02, the Securities to be prepaid shall be selected on a pro rata basis not
more than 60 days prior to the date fixed for prepayment from the outstanding
Securities not previously called for prepayment; PROVIDED, HOWEVER, that with
respect to Securityholders that would be required to hold Securities with an
aggregate principal amount of less than $100,000 but more than an aggregate
principal amount of zero as a result of such pro rata prepayment, the
Corporation shall prepay Securities of each such Securityholder so that after
such prepayment such Securityholder shall hold Securities either with an
aggregate principal amount of at least $100,000 or such Securityholder no longer
holds any Securities, and shall use such method (including, without limitation,
by lot) as the Corporation shall deem fair and appropriate; PROVIDED, FURTHER,
that any such proration may be made on the basis of the aggregate principal
amount of Securities held by each Securityholder and may be made by making such
adjustments as the Corporation deems fair and appropriate in order that only
Securities in denominations of $1,000 or integral multiples thereof shall be
prepaid. The Optional Prepayment Price shall be paid prior to 12:00 noon New
York City time, on the date of such prepayment or at


                                      -56-
<PAGE>   63

such earlier time as the Corporation determines, PROVIDED that the Corporation
shall deposit with the Debenture Trustee an amount sufficient to pay the
Optional Prepayment Price by 10:00 a.m., New York City time, on the date such
Optional Prepayment Price is to be paid.

         (b) Notwithstanding the first sentence of Section 14.02(a), upon the
entry of an order for dissolution of the Trust by a court of competent
jurisdiction, the Securities thereafter will be subject to optional prepayment,
in whole only, but not in part, on or after the Initial Optional Redemption
Date, at the applicable Optional Prepayment Price and otherwise in accordance
with this Article XIV.

         (c) Any prepayment of Securities pursuant to Section 14.01 or Section
14.02 shall be subject to the Corporation obtaining any and all required
regulatory approvals.

         SECTION 14.03  NO SINKING FUND.

         The Securities are not entitled to the benefit of any sinking fund.

         SECTION 14.04 NOTICE OF PREPAYMENT; SELECTION OF SECURITIES.

         In case the Corporation shall desire to exercise the right to prepay
all, or, as the case may be, any part of the Securities in accordance with their
terms, it shall fix a date for prepayment and shall mail a notice of such
prepayment at least 30 and not more than 60 days' prior to the date fixed for
prepayment to the holders of Securities to be so prepaid as a whole or in part
at their last addresses as the same appear on the Security Register. Such
mailing shall be by first class mail. The notice if mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives such notice. In any case, failure to give such notice by
mail or any defect in the notice to the holder of any Security designated for
prepayment as a whole or in part shall not affect the validity of the
proceedings for the prepayment of any other Security.

         Each such notice of prepayment shall specify the CUSIP number of the
Securities to be prepaid, the date fixed for prepayment, the Prepayment Price at
which the Securities are to be prepaid (or the method by which such Prepayment
Price is to be calculated), the place or places of payment where payment will be
made upon presentation and surrender of the Securities, that interest accrued to
the date fixed for prepayment will be paid as specified in said notice, and that
on and after said date interest thereon or on the portions thereof to be prepaid
will cease to accrue. If less than all the Securities are to be prepaid, the
notice of prepayment shall specify the numbers of the Securities to be prepaid.
In case any Security is to be prepaid in part only, the notice of prepayment
shall state the portion of the principal amount thereof to be prepaid and shall
state that on and after the date fixed for prepayment, upon surrender of such
Security, a new Security or Securities in principal amount equal to the portion
thereof that has not been prepaid will be issued.

         By 10:00 a.m., New York City time, on the prepayment date specified in
the notice of prepayment given as provided in this Section, the Corporation will
deposit with the Debenture Trustee or with one or more paying agents an amount
of money sufficient to prepay on the prepayment date all the Securities so
called for prepayment at the Prepayment Price .

         SECTION 14.05 PAYMENT OF SECURITIES CALLED FOR PREPAYMENT.

         If notice of prepayment has been given as provided in Section 14.04,
the Securities or portions of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the Prepayment Price (subject to the rights of holders
of Securities at the close of business on a regular record date in respect of an
Interest Payment Date occurring on or prior to the prepayment date) and on and
after said date (unless the Corporation shall default in the payment of such
Securities at the Prepayment Price interest (including Compounded Interest and
Additional Sums, if any) and Liquidated Damages, if any, on the Securities or
portions of Securities so called for prepayment shall cease to accrue. On
presentation and surrender of such Securities at a place of payment specified in
said notice, the said Securities or the specified portions thereof shall be paid
and prepaid by the Corporation at the applicable Prepayment Price, (subject to
the rights of holders of Securities on the close of business on a regular record
date in respect of an Interest Payment Date occurring on or prior to the
prepayment date).

         Upon presentation of any Security prepaid in part only, the Corporation
shall execute and the Debenture Trustee shall authenticate and make available
for delivery to the holder thereof, at the expense of the Corporation, a new
Security or Securities of authorized denominations, in principal amount equal to
the portion of the Security so presented that has not been prepaid.


                                   ARTICLE XV
                           SUBORDINATION OF SECURITIES

         SECTION 15.01  AGREEMENT TO SUBORDINATE

         The Corporation covenants and agrees, and each holder of Securities
issued hereunder likewise covenants and agrees, that the Securities shall be
issued subject to the provisions of this Article XV; and each holder of a
Security, whether upon original issue or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions.

         The payment by the Corporation of the principal of, premium, if any,
and interest (including Compounded Interest and Additional Sums, if any) and
Liquidated Damages, if any, on all Securities issued hereunder shall, to the
extent and in the manner hereinafter set forth, be subordinated and subject in
right of payment to the prior payment in full of all Allocable Amounts then due
and payable in respect of Senior Indebtedness, whether outstanding at the date
of this Indenture or thereafter incurred.

         No provision of this Article XV shall prevent the occurrence of any
Default or Event of Default hereunder.

         SECTION 15.02 DEFAULT ON SENIOR INDEBTEDNESS.

         In the event and during the continuation of any default by the
Corporation in the payment of principal, premium, interest or any other payment
due on any Senior Indebtedness, or in the event


                                      -58-
<PAGE>   65

that the maturity of any Senior Indebtedness has been accelerated because of a
default and such acceleration has not been rescinded or canceled, then, in
either case, no payment shall be made by the Corporation with respect to the
principal (including prepayment payments) of (or premium, if any) or interest on
the Securities (including Compounded Interest and Additional Sums, if any, and
Liquidated Damages, if any, or any other amounts which may be due on the
Securities pursuant to the terms hereof or thereof). This restriction does not
apply if the total amount outstanding for such Senior Indebtedness in default is
less than $100,000; PROVIDED, such default does not relate to the indebtedness
under the loan agreement by and between the Corporation and LaSalle National
Bank currently outstanding as of the date hereof.

         In the event of the acceleration of the maturity of the Securities,
then no payment shall be made by the Corporation with respect to the principal
(including prepayment payments) of (or premium, if any) or interest on the
Securities (including Compounded Interest and Additional Sums, if any, and
Liquidated Damages, if any, or any other amounts which may be due on the
Securities pursuant to the terms hereof or thereof) until the holders of all
Senior Indebtedness outstanding at the time of such acceleration shall receive
payment, in full, of all Allocable Amounts due on or in respect of such Senior
Indebtedness (including any amounts due upon acceleration).

         In the event that, notwithstanding the foregoing, any payment is
received by the Debenture Trustee, or any Securityholder, when such payment is
prohibited by the preceding paragraphs of this Section 15.02, such payment shall
be held in trust for the benefit of, and shall be paid over or delivered by the
Debenture Trustee (if the notice requested by Section 15.06 has been received by
the Debenture Trustee) or by any Securityholder, to the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent of
the Allocable Amounts in respect of such Senior Indebtedness and to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Debenture Trustee in writing within 90
days of such payment of the Allocable Amounts then due and owing on such Senior
Indebtedness, and only the Allocable Amounts specified in such notice to the
Debenture Trustee shall be paid to the holders of such Senior Indebtedness.

         SECTION 15.03  LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any payment by the Corporation or distribution of assets of the
Corporation of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution, winding-up, liquidation or reorganization of
the Corporation, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, the holders of all Senior Indebtedness of the
Corporation will first be entitled to receive payment in full of Allocable
Amounts due on or in respect of such Senior Indebtedness, before any payment is
made by the Corporation on account of the principal of (or premium, if any) or
interest on the Securities (including Compounded Interest and Additional Sums
(if any) and Liquidated Damages, if any, or any other amounts which may be due
on the Securities pursuant to the terms hereof or thereof); and upon any such
dissolution, winding-up, liquidation or reorganization, any payment by the
Corporation, or distribution of assets of the Corporation of any kind or
character, whether in cash, property or securities, which the Securityholders or
the Debenture Trustee would be entitled to receive from the Corporation, except
for the provisions of this Article XV, shall be paid by the Corporation or by
any receiver, trustee in



                                      -59-
<PAGE>   66

bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Securityholders or by the Debenture Trustee under the
Indenture if received by them or it, directly to the holders of Senior
Indebtedness of the Corporation (pro rata to such holders on the basis of the
respective Allocable Amounts of Senior Indebtedness held by such holders, as
calculated by the Corporation) or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay all such Allocable Amounts
of Senior Indebtedness in full, in money or moneys worth, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to the Securityholders
or to the Debenture Trustee.

         In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Corporation of any kind or character prohibited by
the foregoing, whether in cash, property or securities, shall be received by the
Debenture Trustee, or any Securityholder, before the Allocable Amounts of all
Senior Indebtedness is paid in full, or provision is made for such payment in
money in accordance with its terms, such payment or distribution shall be held
in trust for the benefit of and shall be paid over or delivered by the Debenture
Trustee (if the Notice requested by Section 15.06 has been received by the
Debenture Trustee) or by any Securityholder, to the holders of such Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, as their respective interests may
appear, as calculated by the Corporation, for application to the payment of all
Allocable Amounts of Senior Indebtedness remaining unpaid to the extent
necessary to pay all Allocable Amounts due on or in respect of such Senior
Indebtedness in full in money in accordance with its terms, after giving effect
to any concurrent payment or distribution to or for the benefit of the holders
of such Senior Indebtedness.

         For purposes of this Article XV, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Corporation as
reorganized or readjusted, or securities of the Corporation or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this Article
XV with respect to the Securities to the payment of Senior Indebtedness that may
at the time be outstanding, PROVIDED that (i) such Senior Indebtedness is
assumed by the new corporation, if any, resulting from any such reorganization
or readjustment, and (ii) the rights of the holders of such Senior Indebtedness
are not, without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Corporation with, or the merger of the
Corporation into, another Person or the liquidation or dissolution of the
Corporation following the sale, conveyance, transfer or lease of its property as
an entirety, or substantially as an entirety, to another Person upon the terms
and conditions provided for in Article X of this Indenture shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 15.03 if such other Person shall, as a part of such consolidation,
merger, sale, conveyance, transfer or lease, comply with the conditions stated
in Article X of this Indenture. Nothing in Section 15.02 or in this Section
15.03 shall apply to claims of, or payments to, the Debenture Trustee under or
pursuant to Section 6.06 of this Indenture.

         SECTION 15.04  SUBROGATION.

         Subject to the payment in full of all Allocable Amounts of Senior
Indebtedness, the rights of the Securityholders shall be subrogated to the
rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Corporation, as the case
may be, applicable to such Senior Indebtedness until the principal of (and
premium, if any) and interest on the Securities shall be paid in full; and, for
the purposes of such subrogation, no payments or distributions to the holders of
such Senior Indebtedness of any cash, property or securities to which the
Securityholders or the Debenture Trustee would be entitled except for the
provisions of this Article XV, and no payment over pursuant to the provisions of
this Article XV to or for the benefit of the holders of such Senior Indebtedness
by Securityholders or the Debenture Trustee, shall, as between the Corporation,
its creditors other than holders of Senior Indebtedness of the Corporation, and
the holders of the Securities, be deemed to be a payment by the Corporation to
or on account of such Senior Indebtedness. It is understood that the provisions
of this Article XV are and are intended solely for the purposes of defining the
relative rights of the holders of the Securities, on the one hand, and the
holders of such Senior Indebtedness on the other hand.

         Nothing contained in this Article XV or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Corporation,
its creditors other than the holders of Senior Indebtedness of the Corporation,
and the holders of the Securities, the obligation of the Corporation, which is
absolute and unconditional, to pay to the holders of the Securities the
principal of (and premium, if any) and interest (including Compounded Interest
and Additional Sums, if any) and Liquidated Damages, if any, on the Securities
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the holders of
the Securities and creditors of the Corporation, as the case may be, other than
the holders of Senior Indebtedness of the Corporation, as the case may be, nor
shall anything herein or therein prevent the Debenture Trustee or the holder of
any Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article XV of the holders of such Senior Indebtedness in respect of cash,
property or securities of the Corporation, as the case may be, received upon the
exercise of any such remedy.

         SECTION 15.05  DEBENTURE TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Securityholder, by such Securityholder's acceptance thereof,
authorizes and directs the Debenture Trustee on such Securityholder's behalf to
take such action (as the Debenture Trustee, in its discretion, deems necessary
or appropriate, upon instruction or otherwise) to effectuate the subordination
provided in this Article XV and appoints the Debenture Trustee such
Securityholder's attorney-in-fact for any and all such purposes.

         SECTION 15.06 NOTICE BY THE CORPORATION.

         The Corporation shall give prompt written notice to a Responsible
Officer of the Debenture Trustee of any fact known to the Corporation that would
prohibit the making of any payment of monies to or by the Debenture Trustee in
respect of the Securities pursuant to the provisions of this Article XV.
Notwithstanding the provisions of this Article XV or any other provision of this
Indenture, the Debenture Trustee shall not be charged with knowledge of the
existence of any facts



                                      -61-
<PAGE>   68

that would prohibit the making of any payment of monies to or by the Debenture
Trustee in respect of the Securities pursuant to the provisions of this Article
XV, unless and until a Responsible Officer of the Debenture Trustee shall have
received written notice thereof from the Corporation or a holder or holders of
Senior Indebtedness or from any trustee therefor; and before the receipt of any
such written notice, the Debenture Trustee, subject to the provisions of Article
VI of this Indenture, shall be entitled in all respects to assume that no such
facts exist; PROVIDED, HOWEVER, that if the Debenture Trustee shall not have
received the notice provided for in this Section 15.06 at least two Business
Days prior to the date upon which, by the terms hereof, any money may become
payable for any purpose (including, without limitation, the payment of the
principal of (or premium, if any) or interest (including Compounded Interest and
Additional Sums, if any) and Liquidated Damages, if any, on any Security), then,
anything herein contained to the contrary notwithstanding, the Debenture Trustee
shall have full power and authority to receive such money and to apply the same
to the purposes for which they were received, and shall not be affected by any
notice to the contrary that may be received by it within two Business Days prior
to such date.

         The Debenture Trustee, subject to the provisions of Article VI of this
Indenture, shall be entitled to conclusively rely on a written notice delivered
to it by a Person representing himself to be a holder of Senior Indebtedness of
the Corporation (or a trustee on behalf of such holder), as the case may be, to
establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee on behalf of any such holder or holders. In the event
that the Debenture Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of such Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article XV, the Debenture Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Debenture Trustee as to the amount of such
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article XV, and, if such
evidence is not furnished, the Debenture Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

         Upon any payment or distribution of assets of the Corporation referred
to in this Article XV, the Debenture Trustee, subject to the provisions of
Article VI of this Indenture, and the Securityholders shall be entitled to
conclusively rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding-up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
person making such payment or distribution, delivered to the Debenture Trustee
or to the Securityholders, for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the holders of Senior
Indebtedness and other indebtedness of the Corporation, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XV.

         SECTION 15.07 RIGHTS OF THE DEBENTURE TRUSTEE; HOLDERS OF SENIOR
INDEBTEDNESS.

         The Debenture Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article XV in respect of any Senior
Indebtedness at any time held by it, to the same extent as


                                      -62-
<PAGE>   69

any other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Debenture Trustee of any of its rights as such holder.

         With respect to the holders of Senior Indebtedness of the Corporation,
the Debenture Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article XV, and
no implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Debenture Trustee.
The Debenture Trustee shall not be deemed to owe any fiduciary duty to the
holders of such Senior Indebtedness and, subject to the provisions of Article VI
of this Indenture, the Debenture Trustee shall not be liable to any holder of
such Senior Indebtedness if it shall pay over or deliver to Securityholders, the
Corporation or any other Person money or assets to which any holder of such
Senior Indebtedness shall be entitled by virtue of this Article XV or otherwise.

         Nothing in this Article XV shall apply to claims of, or payments to,
the Debenture Trustee under or pursuant to Section 6.06.

         SECTION 15.08  SUBORDINATION MAY NOT BE IMPAIRED.

         No right of any present or future holder of any Senior Indebtedness of
the Corporation to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Corporation, as the case may be, or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Corporation, as the
case may be, with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof that any such holder may have or otherwise
be charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Corporation may, at any time and from
time to time, without the consent of or notice to the Debenture Trustee or the
Securityholders, without incurring responsibility to the Securityholders and
without impairing or releasing the subordination provided in this Article XV or
the obligations hereunder of the holders of the Securities to the holders of
such Senior Indebtedness, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, such Senior Indebtedness, or otherwise amend or supplement in any manner
such Senior Indebtedness or any instrument evidencing the same or any agreement
under which such Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing such Senior Indebtedness; (iii) release any Person liable in any manner
for the collection of such Senior Indebtedness; and (iv) exercise or refrain
from exercising any rights against the Corporation, as the case may be, and any
other Person.

                                   ARTICLE XVI
                      EXTENSION OF INTEREST PAYMENT PERIOD

         SECTION 16.01  EXTENSION OF INTEREST PAYMENT PERIOD.

         So long as no Event of Default has occurred and is continuing, the
Corporation shall have the right, at any time and from time to time during the
term of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding 10



                                      -63-
<PAGE>   70

consecutive semi-annual periods, including the first such semi-annual period
during such extension period (the "Extended Interest Payment Period"), during
which Extended Interest Payment Period no interest shall be due and payable,
PROVIDED that no Extended Interest Payment Period shall end on a date other than
an Interest Payment Date or extend beyond the Maturity Date. To the extent
permitted by applicable law, interest, the payment of which has been deferred
because of the extension of the interest payment period pursuant to this Section
16.01, will bear interest thereon at the Coupon Rate compounded semi-annually
for each semi-annual period during the Extended Interest Payment Period
("Compounded Interest"). At the end of the Extended Interest Payment Period, the
Corporation shall pay all interest accrued and unpaid on the Securities,
including any Additional Sums and Compounded Interest (together, "Deferred
Interest"), that shall be payable to the holders of the Securities in whose
names the Securities are registered in the Security Register on the record date
immediately preceding the end of the Extended Interest Payment Period. Before
the termination of any Extended Interest Payment Period, the Corporation may
further defer payments of interest by further extending such Extended Interest
Payment Period, PROVIDED that such Extended Interest Payment Period, together
with all such previous and further extensions within such Extended Interest
Payment Period, shall not (i) exceed 10 consecutive semi-annual periods,
including the first such semi-annual period during such Extended Interest
Payment Period, (ii) end on a date other than an Interest Payment Date or (iii)
extend beyond the Maturity Date of the Securities. Upon the termination of any
Extended Interest Payment Period and the payment of all amounts then due, the
Corporation may commence a new Extended Interest Payment Period, subject to the
foregoing requirements. No interest shall be due and payable during an Extended
Interest Payment Period, except at the end thereof, but the Corporation may
prepay at any time all or any portion of the interest accrued during an Extended
Interest Payment Period.

         SECTION 16.02 NOTICE OF EXTENSION.

         (a) If the Property Trustee is the only holder of the Securities at the
time the Corporation elects to commence an Extended Interest Payment Period, the
Corporation shall give written notice to the Administrative Trustees, the
Property Trustee and the Debenture Trustee of its election to commence such
Extended Interest Payment Period at least five Business Days before the earlier
of (i) the next succeeding date on which Distributions on the Trust Securities
would have been payable, and (ii) the date the Property Trustee is required to
give notice of the record date, or the date such Distributions are payable, to
any national securities exchange or to holders of the Capital Securities, but in
any event at least five Business Days before such record date.

         (b) If the Property Trustee is not the only holder of the Securities at
the time the Corporation elects to commence an Extended Interest Payment Period,
the Corporation shall give the holders of the Securities and the Debenture
Trustee written notice of its election of such Extended Interest Payment Period
at least 10 Business Days before the earlier of (i) the next succeeding Interest
Payment Date, and (ii) the date the Debenture Trustee is required to give notice
of the record or payment date of such interest payment to any national
securities exchange.

         (c) The semi-annual period in which any notice is given pursuant to
paragraphs (a) or (b) of this Section 16.02 shall be counted as one of the 10
semi-annual periods permitted in the maximum Extended Interest Payment Period
permitted under Section 16.01.

         Wilmington Trust Company hereby accepts the trusts in this Indenture
declared and provided, upon the terms and conditions hereinabove set forth.

            9.875% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE

                     DUE OCTOBER 15, 2029 Series A/Series B

         BancFirst Ohio Corp., an Ohio corporation (the "Corporation," which
term includes any successor Person under the Indenture hereinafter referred to),
for value received, hereby promises to pay to BFOH Capital Trust I or registered
assigns, the principal sum of $20,619,000 (Twenty Million Six Hundred Nineteen
Thousand Dollars) on October 15, 2029 (the "Maturity Date"), unless previously
prepaid, and to pay interest on the outstanding principal amount hereof from
October 18, 1999, or from the most recent interest payment date (each such date,
an "Interest Payment Date") to which interest has been paid or duly provided
for, semi-annually (subject to deferral as set forth herein) in arrears on April
15 and October 15 of each year, commencing April 15, 2000 at the rate of __% per
annum, until the principal hereof shall have become due and payable, and on any
overdue principal and premium, if any, and (without duplication and to the
extent that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at the same rate per annum compounded
semi-annually ("Compounded Interest"). The amount of interest payable hereon
shall be computed on the basis of a 360-day year of twelve 30- day months. In
the event that any date on which the principal of (or premium, if any) or
interest on this Security is payable is not a Business Day (as defined in the
Indenture), then the payment payable on such date will be made on the next
succeeding day that is a Business Year, except that if such next succeeding
Business Day falls in the next succeeding calendar month such payment shall be
made on the immediately preceding Business Day (and without any interest or
other payment in respect of any such delay), with the same force and effect as
if made on such date. Pursuant to the Indenture, in certain circumstances the
Corporation will be required to pay Additional Sums (as defined in the
Indenture) with respect to this Security. Pursuant to the Registration Rights
Agreement and the Liquidated Damages Agreement, in certain limited circumstances
the Corporation will be required to pay Liquidated Damages (as defined in the
Registration Rights Agreement and the Liquidated Damages Agreement) with respect
to this Security.

         The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, which shall be at the
close of business on the first day of the month in which the relevant Interest
Payment Date falls. Any such interest installment not punctually paid or duly
provided for shall forthwith cease to be payable to the holders on such regular
record date and may be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a special
record date to be fixed by the Debenture Trustee for the payment of such
defaulted interest, notice whereof shall be given to the holders of Securities
not less than 10 days prior to such special record date, or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any


                                      A-4

securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

         The principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) and Liquidated Damages, if any,
on this Security shall be payable at the office or agency of the Debenture
Trustee maintained for that purpose in any coin or currency of the United States
of America that at the time of payment is legal tender for payment of public and
private debts; PROVIDED, HOWEVER, that payment of interest may be made at the
option of the Corporation by (i) check mailed to the holder at such address as
shall appear in the Security Register or (ii) transfer to an account maintained
by the Person entitled thereto, provided that proper written transfer
instructions have been received by the relevant record date. Notwithstanding the
foregoing, so long as the holder of this Security is the Property Trustee of
BFOH Capital Trust I, the payment of the principal of (and premium, if any) and
interest (including Compounded Interest and Additional Sums, if any) and
Liquidated Damages, if any, on this Security will be made at such place and to
such account as may be designated by such Property Trustee.

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and junior in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Debenture Trustee on his or her
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination so provided and (c) appoints the Debenture Trustee
his or her attorney-in-fact for any and all such purposes. Each holder hereof,
by his or her acceptance hereof, hereby waives all notice of the acceptance of
the subordination provisions contained herein and in the Indenture by each
holder of Senior Indebtedness, whether now outstanding or hereafter incurred,
and waives reliance by each such holder upon said provisions.

         This Security shall not be entitled to any benefit under the Indenture
or be valid or become obligatory for any purpose until the Certificate of
Authentication hereon shall have been signed by or on behalf of the Debenture
Trustee.

         The provisions of this Security are continued on the reverse side
hereof and such provisions shall for all purposes have the same effect as though
fully set forth at this place.

                          (FORM OF REVERSE OF SECURITY)

         This Security is one of the Securities of the Corporation (herein
sometimes referred to as the "Securities"), specified in the Indenture, all
issued or to be issued under and pursuant to an Indenture, dated as of October
18, 1999 (the "Indenture"), duly executed and delivered between the Corporation
and Wilmington Trust Company, as Debenture Trustee (the "Debenture Trustee"), to
which Indenture reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Debenture Trustee, the Corporation and the holders of the Securities.

         Upon the occurrence and continuation of a Special Event (as defined in
the Indenture) prior to October 15, 2009 (the "Initial Optional Redemption
Date"), the Corporation shall have the right, at any time within 90 days
following the occurrence of such Special Event, to prepay this Security in whole
(but not in part) at the Special Event Prepayment Price. "Special Event
Prepayment Price" shall mean, with respect to any prepayment of the Securities
following a Special Event, an amount in cash equal to the greater of (i) 100% of
the principal amount of the Securities to be prepaid, or (ii) the sum, as
determined by a Quotation Agent, of the present values of the remaining
scheduled payments of principal and interest on such Securities, discounted to
the prepayment date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Adjusted Treasury Rate, plus, in the case of
each of (i) and (ii), any accrued and unpaid interest (including Compounded
Interest and Additional Sums, if any) and Liquidated Damages, if any, thereon to
the date of such prepayment.

         In addition, the Corporation shall have the right to prepay this
Security, in whole or in part, at any time on or after the Initial Optional
Redemption Date (an "Optional Prepayment"), at the prepayment prices set forth
below plus, in each case, accrued and unpaid interest thereon (including
Compounded Interest and Additional Sums, if any) and Liquidated Damages, if any,
thereon to the applicable date of prepayment (the "Optional Prepayment Price"),
if prepaid during the 12-month period beginning October 15, of the years

         The Prepayment Price shall be paid prior to 12:00 noon, New York City
time, on the date of such prepayment or at such earlier time as the Corporation
determines, PROVIDED that the Corporation shall deposit with the Debenture
Trustee an amount sufficient to pay the Prepayment Price by 10:00 a.m., New York
City time, on the date such Prepayment Price is to be paid. Any prepayment
pursuant to this paragraph will be made upon not less than 30 days nor more than
60 days' prior written notice.

         If the Securities are only partially prepaid by the Corporation
pursuant to an Optional Prepayment, the particular Securities to be prepaid
shall be selected on a pro rata basis from the outstanding Securities not
previously called for prepayment; PROVIDED, HOWEVER, that with respect to
Securityholders that would be required to hold Securities with an aggregate
principal amount of less than $100,000 but more than an aggregate principal
amount of zero as a result of such pro rata prepayment, the Corporation shall
prepay Securities of each such Securityholder so that after such prepayment such
Securityholder shall hold Securities either with an aggregate principal amount
of at least $100,000 or such Securityholder no longer holds any Securities and
shall use such method (including, without limitation, by lot) as the Corporation
shall deem fair and appropriate; PROVIDED, FURTHER, that any such proration may
be made on the basis of the aggregate principal amount of Securities held by
each Securityholder thereof and may be made by making such adjustments as the
Corporation deems fair and appropriate in order that only Securities in
denominations of $1,000 or integral multiples thereof shall be prepaid. In the
event of prepayment of this Security in part only, a new Security or Securities
for the portion hereof that has not been prepaid will be issued in the name of
the holder hereof upon the cancellation hereof.

         Notwithstanding the foregoing, any prepayment of Securities by the
Corporation shall be subject to the receipt of any and all required regulatory
approvals.

         In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of all of the Securities may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Corporation and the
Debenture Trustee, with the consent of the holders of a majority in aggregate
principal amount of the Securities at the time outstanding (as defined in the
Indenture), to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of modifying in any manner the rights of the holders of the
Securities; PROVIDED, HOWEVER, that no such supplemental indenture shall,
without the consent of each holder of Securities then outstanding and affected
thereby, (i) change the Maturity Date of any Security, or reduce the rate or
extend the time of payment of interest thereon (subject to Article XVI of the
Indenture), or reduce the principal amount thereof, or change any of the
prepayment provisions or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than U.S. dollars, or impair or
affect the right of any holder of Securities to institute suit for payment
thereof, or (ii) reduce the aforesaid percentage of Securities the holders of
which are required to consent to any such supplemental indenture. The Indenture
also contains provisions permitting the holders of a majority in aggregate
principal amount of the Securities at the time outstanding affected thereby, on
behalf of all of the holders of the Securities, to waive any past default in the
performance of any of the covenants contained in the Indenture, or established
pursuant to the Indenture, and its


                                      A-8
<PAGE>   80

consequences, except a default in the payment of the principal of or premium, if
any, or interest on any of the Securities or a default in respect of any
covenant or provision under which the Indenture cannot be modified or amended
without the consent of each holder of Securities then outstanding. Any such
consent or waiver by the holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such holder and upon all
future holders and owners of this Security and of any Security issued in
exchange herefor or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of such consent or
waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Corporation,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest (including Compounded Interest and Additional Sums, if any)
and Liquidated Damages, if any, on this Security at the time and place and at
the rate and in the money herein prescribed.

         So long as no Event of Default shall have occurred and be continuing,
the Corporation shall have the right, at any time and from time to time during
the term of the Securities, to defer payments of interest by extending the
interest payment period (an "Extended Interest Payment Period") of such
Securities for a period not (i) exceeding 10 consecutive semi-annual periods,
including the first such semi-annual period during such extension period, (ii)
extending beyond the Maturity Date of the Securities or (iii) ending on a date
other than an Interest Payment Date, at the end of which period the Corporation
shall pay all interest then accrued and unpaid (together with interest thereon
at the rate specified for the Securities to the extent that payment of such
interest is enforceable under applicable law). Before the termination of any
such Extended Interest Payment Period, the Corporation may further defer
payments of interest by further extending such Extended Interest Payment Period,
PROVIDED that such Extended Interest Payment Period, together with all such
previous and further extensions within such Extended Interest Payment Period,
(i) shall not exceed 10 consecutive semi-annual periods including the first
semi-annual period during such Extended Interest Payment Period, (ii) shall not
end on any date other than an Interest Payment Date, and (iii) shall not extend
beyond the Maturity Date of the Securities. Upon the termination of any such
Extended Interest Payment Period and the payment of all accrued and unpaid
interest and any additional amounts then due, the Corporation may commence a new
Extended Interest Payment Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof, but the Corporation may prepay at any time all or any
portion of the interest accrued during an Extended Interest Payment Period.

         The Corporation has agreed that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock,
(ii) make any payment of principal of or interest or premium, if any, on or
repay, repurchase or redeem any debt securities (including other Debentures) of
the Corporation that rank pari passu with or junior in right of payment to the
Securities or (iii) make any guarantee payments with respect to any guarantee by
the Corporation of the debt securities of any Subsidiary of the Corporation
(including Other Guarantees) if such guarantee ranks pari passu with or junior
in right of payment to the Securities (other than (a) dividends or distributions
of Corporation's capital stock (which includes Common Stock and preferred
stock), (b) any declaration of a dividend in connection with the implementation
of a stockholders' rights plan, or the issuance of stock under any such plan in
the future, or the redemption or repurchase of any such rights pursuant thereto,
(c)

payments under the Capital Securities Guarantee, as defined in the Indenture,
(d) as a result of a reclassification of the Corporation's capital stock or the
exchange or conversion of one class or series of the Corporation's capital stock
for another class or series of the Corporation's capital stock, (e) the purchase
of fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged, and (f) purchases of Common Stock related to the
issuance of Common Stock or rights under any of the Corporation's benefit or
compensation plans for its directors, officers or employees or any of the
Corporation's dividend reinvestment plans), if at such time (1) there shall have
occurred any event of which the Corporation has actual knowledge that (a) is, or
with the giving of notice or the lapse of time, or both, would constitute, an
Event of Default and (b) in respect of which the Corporation shall not have
taken reasonable steps to cure, (2) if such Securities are held by the Property
Trustee of BFOH Capital Trust I, the Corporation shall be in default with
respect to its payment of any obligations under the Capital Securities Guarantee
or (3) the Corporation shall have given notice of its election to exercise its
right to commence an Extended Interest Payment Period, and shall not have
rescinded such Notice, and such Extended Interest Payment Period or any
extension thereof shall have commenced and be continuing.

         Subject to (i) the Corporation having received any required regulatory
approvals and (ii) the Administrative Trustees of BFOH Capital Trust I having
received an opinion of counsel to the effect that such distribution will not
cause the holders of Capital Securities to recognize gain or loss for federal
income tax purposes, the Corporation will have the right at any time to
liquidate the Trust and, after satisfaction of liabilities of creditors of the
Trust as required by applicable law, to cause the Securities to be distributed
to the holders of the Trust Securities in liquidation of the Trust.

         The Securities are issuable only in registered form without coupons in
minimum denominations of $100,000 and multiples of $1,000 in excess thereof. As
provided in the Indenture and subject to the transfer restrictions limitations
as may be contained herein and therein from time to time, this Security is
transferable by the holder hereof on the Security Register of the Corporation,
upon surrender of this Security for registration of transfer at the office or
agency of the Corporation in Wilmington, Delaware accompanied by a written
instrument or instruments of transfer in form satisfactory to the Corporation or
the Debenture Trustee duly executed by the holder hereof or his or her attorney
duly authorized in writing, and thereupon one or more new Securities of
authorized denominations and for the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Corporation may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in relation thereto.

         Prior to due presentment for registration of transfer of this Security,
the Corporation, the Debenture Trustee, any authenticating agent, any paying
agent, any transfer agent and the security registrar may deem and treat the
holder hereof as the absolute owner hereof (whether or not this Security shall
be overdue and notwithstanding any notice of ownership or writing hereon made by
anyone other than the security registrar for the Securities) for the purpose of
receiving payment of or on account of the principal hereof and premium, if any,
and (subject to the Indenture) interest due hereon and for all other purposes,
and neither the Corporation nor the Debenture Trustee nor any authenticating
agent nor any paying agent nor any transfer agent nor any security registrar
shall be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or
premium, if any, or interest (including Compounded Interest and Additional Sums,
if any) or Liquidated Damages, if any, on this Security, or for any claim based
hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture, against any incorporator, stockholder, employee, officer or director,
past, present or future, as such, of the Corporation or of any predecessor or
successor Person, whether by virtue of any constitution, statute or rule of law,
or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issuance hereof, expressly waived and released.

         All terms used in this Security that are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAW PRINCIPLES THEREOF.

            9.875% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE

                          DUE OCTOBER 15, 2029 Series B

         BancFirst Ohio Corp., an Ohio corporation (the "Corporation," which
term includes any successor Person under the Indenture hereinafter referred to),
for value received, hereby promises to pay to BFOH Capital Trust I or registered
assigns, the principal sum of $20,619,000 (Twenty Million Six Hundred Nineteen
Thousand Dollars) on October 15, 2029 (the "Maturity Date"), unless previously
prepaid, and to pay interest on the outstanding principal amount hereof from
October 18, 1999, or from the most recent interest payment date (each such date,
an "Interest Payment Date") to which interest has been paid or duly provided
for, semi-annually (subject to deferral as set forth herein) in arrears on April
15 and October 15 of each year, commencing April 15, 2000 at the rate of __% per
annum, until the principal hereof shall have become due and payable, and on any
overdue principal and premium, if any, and (without duplication and to the
extent that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at the same rate per annum compounded
semi-annually ("Compounded Interest"). The amount of interest payable hereon
shall be computed on the basis of a 360-day year of twelve 30- day months. In
the event that any date on which the principal of (or premium, if any) or
interest on this Security is payable is not a Business Day (as defined in the
Indenture), then the payment payable on such date will be made on the next
succeeding day that is a Business Year, except that if such next succeeding
Business Day falls in the next succeeding calendar month such payment shall be
made on the immediately preceding Business Day (and without any interest or
other payment in respect of any such delay), with the same force and effect as
if made on such date. Pursuant to the Indenture, in certain circumstances the
Corporation will be required to pay Additional Sums (as defined in the
Indenture) with respect to this Security.

         The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, which shall be at the
close of business on the first day of the month in which the relevant Interest
Payment Date falls. Any such interest installment not punctually paid or duly
provided for shall forthwith cease to be payable to the holders on such regular
record date and may be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a special
record date to be fixed by the Debenture Trustee for the payment of such
defaulted interest, notice whereof shall be given to the holders of Securities
not less than 10 days prior to such special record date, or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

         The principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) on this Security shall be
payable at the office or agency of the Debenture Trustee maintained for that
purpose in any coin or currency of the United States of America that at the time
of payment is legal tender for payment of public and private debts; PROVIDED,
HOWEVER, that payment of interest may be made at the option of the Corporation
by (i) check mailed to the holder at such address as shall appear in the
Security Register or (ii) transfer to an account maintained by the Person
entitled thereto, provided that proper written transfer instructions have been
received by the relevant record date. Notwithstanding the foregoing, so long as
the holder of this Security is the Property Trustee of BFOH Capital Trust I, the
payment of the principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) on this Security will be made
at such place and to such account as may be designated by such Property Trustee.

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and junior in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Debenture Trustee on his or her
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination so provided and (c) appoints the Debenture Trustee
his or her attorney-in-fact for any and all such purposes. Each holder hereof,
by his or her acceptance hereof, hereby waives all notice of the acceptance of
the subordination provisions contained herein and in the Indenture by each
holder of Senior Indebtedness, whether now outstanding or hereafter incurred,
and waives reliance by each such holder upon said provisions.

         This Security shall not be entitled to any benefit under the Indenture
or be valid or become obligatory for any purpose until the Certificate of
Authentication hereon shall have been signed by or on behalf of the Debenture
Trustee.

         The provisions of this Security are continued on the reverse side
hereof and such provisions shall for all purposes have the same effect as though
fully set forth at this place.

                          (FORM OF REVERSE OF SECURITY)

         This Security is one of the Securities of the Corporation (herein
sometimes referred to as the "Securities"), specified in the Indenture, all
issued or to be issued under and pursuant to an Indenture, dated as of October
18, 1999 (the "Indenture"), duly executed and delivered between the Corporation
and Wilmington Trust Company, as Debenture Trustee (the "Debenture Trustee"), to
which Indenture reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Debenture Trustee, the Corporation and the holders of the Securities.

         Upon the occurrence and continuation of a Special Event (as defined in
the Indenture) prior to October 15, 2009 (the "Initial Optional Redemption
Date"), the Corporation shall have the right, at any time within 90 days
following the occurrence of such Special Event, to prepay this Security in whole
(but not in part) at the Special Event Prepayment Price. "Special Event
Prepayment Price" shall mean, with respect to any prepayment of the Securities
following a Special Event, an amount in cash equal to the greater of (i) 100% of
the principal amount of the Securities to be prepaid, or (ii) the sum, as
determined by a Quotation Agent, of the present values of the remaining
scheduled payments of principal and interest on such Securities, discounted to
the prepayment date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Adjusted Treasury Rate, plus, in the case of
each of (i) and (ii), any accrued and unpaid interest (including Compounded
Interest and Additional Sums, if any) thereon to the date of such prepayment.

         In addition, the Corporation shall have the right to prepay this
Security, in whole or in part, at any time on or after the Initial Optional
Redemption Date (an "Optional Prepayment"), at the prepayment prices set forth
below plus, in each case, accrued and unpaid interest thereon (including
Compounded Interest and Additional Sums, if any) thereon to the applicable date
of prepayment (the "Optional Prepayment Price"), if prepaid during the 12-month

         The Prepayment Price shall be paid prior to 12:00 noon, New York City
time, on the date of such prepayment or at such earlier time as the Corporation
determines, PROVIDED that the Corporation shall deposit with the Debenture
Trustee an amount sufficient to pay the Prepayment


                                      A-6

<PAGE>   7

Price by 10:00 a.m., New York City time, on the date such Prepayment Price is to
be paid. Any prepayment pursuant to this paragraph will be made upon not less
than 30 days nor more than 60 days' prior written notice.

         If the Securities are only partially prepaid by the Corporation
pursuant to an Optional Prepayment, the particular Securities to be prepaid
shall be selected on a pro rata basis from the outstanding Securities not
previously called for prepayment; PROVIDED, HOWEVER, that with respect to
Securityholders that would be required to hold Securities with an aggregate
principal amount of less than $100,000 but more than an aggregate principal
amount of zero as a result of such pro rata prepayment, the Corporation shall
prepay Securities of each such Securityholder so that after such prepayment such
Securityholder shall hold Securities either with an aggregate principal amount
of at least $100,000 or such Securityholder no longer holds any Securities and
shall use such method (including, without limitation, by lot) as the Corporation
shall deem fair and appropriate; PROVIDED, FURTHER, that any such proration may
be made on the basis of the aggregate principal amount of Securities held by
each Securityholder thereof and may be made by making such adjustments as the
Corporation deems fair and appropriate in order that only Securities in
denominations of $1,000 or integral multiples thereof shall be prepaid. In the
event of prepayment of this Security in part only, a new Security or Securities
for the portion hereof that has not been prepaid will be issued in the name of
the holder hereof upon the cancellation hereof.

         Notwithstanding the foregoing, any prepayment of Securities by the
Corporation shall be subject to the receipt of any and all required regulatory
approvals.

         In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of all of the Securities may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Corporation and the
Debenture Trustee, with the consent of the holders of a majority in aggregate
principal amount of the Securities at the time outstanding (as defined in the
Indenture), to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of modifying in any manner the rights of the holders of the
Securities; PROVIDED, HOWEVER, that no such supplemental indenture shall,
without the consent of each holder of Securities then outstanding and affected
thereby, (i) change the Maturity Date of any Security, or reduce the rate or
extend the time of payment of interest thereon (subject to Article XVI of the
Indenture), or reduce the principal amount thereof, or change any of the
prepayment provisions or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than U.S. dollars, or impair or
affect the right of any holder of Securities to institute suit for payment
thereof, or (ii) reduce the aforesaid percentage of Securities the holders of
which are required to consent to any such supplemental indenture. The Indenture
also contains provisions permitting the holders of a majority in aggregate
principal amount of the Securities at the time outstanding affected thereby, on
behalf of all of the holders of the Securities, to waive any past default in the
performance of any of the covenants contained in the Indenture, or established
pursuant to the Indenture, and its consequences, except a default in the payment
of the principal of or premium, if any, or interest on any of the Securities or
a default in respect of any covenant or provision under which the Indenture
cannot be modified or


                                      A-7


<PAGE>   8

amended without the consent of each holder of Securities then outstanding. Any
such consent or waiver by the holder of this Security (unless revoked as
provided in the Indenture) shall be conclusive and binding upon such holder and
upon all future holders and owners of this Security and of any Security issued
in exchange herefor or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of such consent or
waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Corporation,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest (including Compounded Interest and Additional Sums, if any) on
this Security at the time and place and at the rate and in the money herein
prescribed.

         So long as no Event of Default shall have occurred and be continuing,
the Corporation shall have the right, at any time and from time to time during
the term of the Securities, to defer payments of interest by extending the
interest payment period (an "Extended Interest Payment Period") of such
Securities for a period not (i) exceeding 10 consecutive semi-annual periods,
including the first such semi-annual period during such extension period, (ii)
extending beyond the Maturity Date of the Securities or (iii) ending on a date
other than an Interest Payment Date, at the end of which period the Corporation
shall pay all interest then accrued and unpaid (together with interest thereon
at the rate specified for the Securities to the extent that payment of such
interest is enforceable under applicable law). Before the termination of any
such Extended Interest Payment Period, the Corporation may further defer
payments of interest by further extending such Extended Interest Payment Period,
PROVIDED that such Extended Interest Payment Period, together with all such
previous and further extensions within such Extended Interest Payment Period,
(i) shall not exceed 10 consecutive semi-annual periods including the first
semi-annual period during such Extended Interest Payment Period, (ii) shall not
end on any date other than an Interest Payment Date, and (iii) shall not extend
beyond the Maturity Date of the Securities. Upon the termination of any such
Extended Interest Payment Period and the payment of all accrued and unpaid
interest and any additional amounts then due, the Corporation may commence a new
Extended Interest Payment Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof, but the Corporation may prepay at any time all or any
portion of the interest accrued during an Extended Interest Payment Period.

         The Corporation has agreed that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock,
(ii) make any payment of principal of or interest or premium, if any, on or
repay, repurchase or redeem any debt securities (including other Debentures) of
the Corporation that rank pari passu with or junior in right of payment to the
Securities or (iii) make any guarantee payments with respect to any guarantee by
the Corporation of the debt securities of any Subsidiary of the Corporation
(including Other Guarantees) if such guarantee ranks pari passu with or junior
in right of payment to the Securities (other than (a) dividends or distributions
of Corporation's capital stock (which includes Common Stock and preferred
stock), (b) any declaration of a dividend in connection with the implementation
of a stockholders' rights plan, or the issuance of stock under any such plan in
the future, or the redemption or repurchase of any such rights pursuant thereto,
(c) payments under the Capital Securities Guarantee, as defined in the
Indenture, (d) as a result of a reclassification of the


                                      A-8

<PAGE>   9

Corporation's capital stock or the exchange or conversion of one class or series
of the Corporation's capital stock for another class or series of the
Corporation's capital stock, (e) the purchase of fractional interests in shares
of the Corporation's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
and (f) purchases of Common Stock related to the issuance of Common Stock or
rights under any of the Corporation's benefit or compensation plans for its
directors, officers or employees or any of the Corporation's dividend
reinvestment plans), if at such time (1) there shall have occurred any event of
which the Corporation has actual knowledge that (a) is, or with the giving of
notice or the lapse of time, or both, would constitute, an Event of Default and
(b) in respect of which the Corporation shall not have taken reasonable steps to
cure, (2) if such Securities are held by the Property Trustee of BFOH Capital
Trust I, the Corporation shall be in default with respect to its payment of any
obligations under the Capital Securities Guarantee or (3) the Corporation shall
have given notice of its election to exercise its right to commence an Extended
Interest Payment Period, and shall not have rescinded such Notice, and such
Extended Interest Payment Period or any extension thereof shall have commenced
and be continuing.

         Subject to (i) the Corporation having received any required regulatory
approvals and (ii) the Administrative Trustees of BFOH Capital Trust I having
received an opinion of counsel to the effect that such distribution will not
cause the holders of Capital Securities to recognize gain or loss for federal
income tax purposes, the Corporation will have the right at any time to
liquidate the Trust and, after satisfaction of liabilities of creditors of the
Trust as required by applicable law, to cause the Securities to be distributed
to the holders of the Trust Securities in liquidation of the Trust.

         The Securities are issuable only in registered form without coupons in
minimum denominations of $100,000 and multiples of $1,000 in excess thereof. As
provided in the Indenture and subject to the transfer restrictions limitations
as may be contained herein and therein from time to time, this Security is
transferable by the holder hereof on the Security Register of the Corporation,
upon surrender of this Security for registration of transfer at the office or
agency of the Corporation in Wilmington, Delaware accompanied by a written
instrument or instruments of transfer in form satisfactory to the Corporation or
the Debenture Trustee duly executed by the holder hereof or his or her attorney
duly authorized in writing, and thereupon one or more new Securities of
authorized denominations and for the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Corporation may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in relation thereto.

         Prior to due presentment for registration of transfer of this Security,
the Corporation, the Debenture Trustee, any authenticating agent, any paying
agent, any transfer agent and the security registrar may deem and treat the
holder hereof as the absolute owner hereof (whether or not this Security shall
be overdue and notwithstanding any notice of ownership or writing hereon made by
anyone other than the security registrar for the Securities) for the purpose of
receiving payment of or on account of the principal hereof and premium, if any,
and (subject to the Indenture) interest due hereon and for all other purposes,
and neither the Corporation nor the Debenture Trustee nor any authenticating
agent nor any paying agent nor any transfer agent nor any security registrar
shall be affected by any notice to the contrary.


                                      A-9

         No recourse shall be had for the payment of the principal of or
premium, if any, or interest (including Compounded Interest and Additional Sums,
if any) on this Security, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture, against any incorporator,
stockholder, employee, officer or director, past, present or future, as such, of
the Corporation or of any predecessor or successor Person, whether by virtue of
any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

         All terms used in this Security that are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAW PRINCIPLES THEREOF.

any such Event of Default and all Events of Default with respect to the Common
Securities and their consequences if all Events of Default with respect to the

such Events of Default have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the Holders of
the Capital Securities and only the Holders of the Capital Securities will have

Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby

with respect to the Common Securities arising therefrom shall be deemed to have
been cured for every purpose of this Declaration, but no such waiver shall
extend to any subsequent or other Default or Event of Default with respect to
the Common Securities or impair any right consequent thereon.

the Property Trustee, at the direction of the Holders of the Capital Securities,

Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of

                      or termination of the Indenture or the Debentures where

                      received an opinion of independent tax counsel experienced
                      in such matters to the effect that such amendment,
                      modification or termination will not cause more than an
                      insubstantial risk that the Trust will not be classified
                      as a grantor trust for United States federal income tax
                      purposes.

SECTION 3.8           POWERS AND DUTIES OF THE PROPERTY TRUSTEE.

                      (a) The legal title to the Debentures shall be owned by
and held of record in the name of the Property Trustee in trust for the benefit
of the Trust and the Holders. The right, title and interest of the Property
Trustee to the Debentures shall vest automatically in each Person who may
hereafter be appointed as Property Trustee in accordance with Section 5.6. Such
vesting and cessation of title shall be effective whether or not conveyancing
documents with regard to the Debentures have been executed and delivered.

                      (b) The Property Trustee shall not transfer its right,
title and interest in the Debentures to the Administrative Trustees or to the
Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

                      (c)    The Property Trustee shall:

                             (i) establish and maintain a segregated
                      non-interest bearing trust account (the "Property Trustee
                      Account") in the name of and under the exclusive control
                      of the Property Trustee on behalf of the Holders and, upon
                      the receipt of payments of funds made in respect of the
                      Debentures held by the Property

                                       18
<PAGE>   25


                      Trustee, deposit such funds into the Property Trustee
                      Account and make payments or cause the Paying Agent to
                      make payments to the Holders from the Property Trustee
                      Account in accordance with Section 6.1; funds in the
                      Property Trustee Account shall be held uninvested until
                      disbursed in accordance with this Declaration; and the
                      Property Trustee Account shall be an account that is
                      maintained with a banking institution the rating on whose
                      long-term unsecured indebtedness by a "nationally
                      recognized statistical rating organization," as that term
                      is defined for purposes of Rule 436(g)(2) under the
                      Securities Act, is at least equal to the rating assigned
                      to the Capital Securities, unless the Capital Securities
                      are not rated, in which case the banking institution's
                      long-term unsecured indebtedness shall be rated at least
                      investment grade by a "nationally recognized statistical
                      rating organization";

                             (ii) engage in such ministerial activities as shall
                      be necessary or appropriate to effect the redemption of
                      the Securities to the extent the Debentures are redeemed
                      or mature; and

                             (iii) upon written notice of distribution issued by
                      the Administrative Trustees in accordance with the terms
                      of the Securities, engage in such ministerial activities
                      as shall be necessary or appropriate to effect the
                      distribution of the Debentures to Holders upon the
                      occurrence of certain events.

                      (d) The Property Trustee shall take all actions and
perform such duties as may be specifically required of the Property Trustee
pursuant to the terms of this Declaration and the Securities.

                      (e) Subject to Section 3.9(a), the Property Trustee shall
take any Legal Action which arises out of or in connection with an Event of
Default of which a Responsible Officer has actual knowledge or the Property
Trustee's duties and obligations under this Declaration or the Trust Indenture
Act; and if the Property Trustee shall have failed to take such Legal Action
following a written request from the Holders, the Holders of the Capital
Securities may, to the fullest extent permitted by law, take such Legal Action,
to the same extent as if such Holders of Capital Securities held an aggregate
principal amount of Debentures equal to the aggregate liquidation amount of such
Capital Securities, without first proceeding against the Property Trustee or the
Trust; PROVIDED, HOWEVER, that if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay the principal of or premium, if any, or interest (including Compounded
Interest and Additional Sums, if any) or Liquidated Damages, if any, on the
Debentures on the date such principal, premium, if any, or interest (including
Compounded Interest and Additional Sums, if any) or Liquidated Damages, if any,
is otherwise payable (or in the case of redemption, on the redemption date),
then a Holder of Capital Securities may directly institute a proceeding for
enforcement of payment to such Holder of the principal of or premium, if any, or
interest (including Compounded Interest and Additional Sums, if any) or
Liquidated Damages, if any, on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Capital Securities of such Holder (a
"Direct Action") on or after the respective due date specified in the
Debentures. In connection with such Direct Action, the Holders of the Common
Securities will be subrogated to the rights of such Holder of Capital Securities
to the extent of any payment made

                                       19
<PAGE>   26



by the Debenture Issuer to such Holder of Capital Securities in such Direct
Action. Except as provided in the preceding sentences, the Holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

                      (f) The Property Trustee shall continue to serve as a
Trustee until either:

                                 (i) the Trust has been completely liquidated
                      and the proceeds of the liquidation distributed to the
                      Holders pursuant to the terms of the Securities and this
                      Declaration; or

                                 (ii) a successor Property Trustee has been
                      appointed and has accepted that appointment in accordance
                      with Section 5.6 (a "Successor Property Trustee").

                      (g) The Property Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Debentures
under the Indenture and, if an Event of Default actually known to a Responsible
Officer occurs and is continuing, the Property Trustee shall, for the benefit of
Holders, enforce its rights as holder of the Debentures subject to the rights of
the Holders pursuant to the terms of this Declaration and the Securities.

                      (h) The Property Trustee shall be authorized to undertake
any actions set forth in ss.317(a) of the Trust Indenture Act.

                      (i) For such time as the Property Trustee is the Paying
Agent, the Property Trustee may authorize one or more Persons to act as
additional Paying Agents and to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all Securities and
any such Paying Agent shall comply with ss. 317(b) of the Trust Indenture Act.
Any such additional Paying Agent may be removed by the Property Trustee at any
time the Property Trustee remains as Paying Agent and a successor Paying Agent
or additional Paying Agents may be (but are not required to be) appointed at any
time by the Property Trustee while the Property Trustee is acting as Paying
Agent.

                      (j) Subject to this Section 3.8, the Property Trustee
shall have none of the duties, liabilities, powers or the authority of the
Administrative Trustees set forth in Section 3.6.

                      Notwithstanding anything expressed or implied to the
contrary in this Declaration or any Annex or Exhibit hereto, (i) the Property
Trustee must exercise the powers set forth in this Section 3.8 in a manner that
is consistent with the purposes and functions of the Trust set out in Section
3.3, and (ii) the Property Trustee shall not take any action that is
inconsistent with the purposes and functions of the Trust set out in Section
3.3.

SECTION 3.9 CERTAIN DUTIES AND RESPONSIBILITIES OF THE PROPERTY TRUSTEE.

                      (a) The Property Trustee, before the occurrence of any
Event of Default (of which, other than in the case of Events of Default under
Sections 5.01(a) and 5.01(b) of the Indenture, which the Property Trustee is
deemed to have knowledge of as provided in Section 2.7(b) hereof, a Responsible
Officer of the Property Trustee has actual knowledge) and after the curing or



                                       20
<PAGE>   27


waiving of all such Events of Default that may have occurred, shall undertake to
perform only such duties as are specifically set forth in this Declaration and
in the Securities and no implied covenants shall be read into this Declaration
against the Property Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.6) of which a Responsible Officer
has actual knowledge, the Property Trustee shall exercise such of the rights and
powers vested in it by this Declaration, and use the same degree of care and
skill in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

                      (b) No provision of this Declaration shall be construed to
relieve the Property Trustee from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

                             (i) prior to the occurrence of an Event of Default
                      (of which, other than in the case of Events of Default
                      under Sections 5.01(a) and 5.01(b) of the Indenture, which
                      the Property Trustee is deemed to have knowledge of as
                      provided in Section 2.7(b) hereof, a Responsible Officer

                    be entitled to direct the Property Trustee under the terms
                    of the Securities in respect of such remedy, right or
                    action, (ii) may refrain from enforcing such remedy or right

                    received, and (iii) shall be protected in conclusively
                    relying on or acting in accordance with such instructions;

                         (xi) except as otherwise expressly provided by this

                    reasonably believed by it to be authorized or within the
                    discretion or rights or powers conferred upon it by this
                    Declaration.

                    (b) No provision of this Declaration shall be deemed to
impose any duty or obligation on the Property Trustee to perform any act or acts
or exercise any right, power, duty or obligation conferred or imposed on it, in
any jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

                    securities substituted for the Common Securities) are
                    listed, quoted or included for trading, or any Successor

will not cause the Holders of Capital Securities to recognize gain or loss for
United States federal income tax purposes and (ii) any required regulatory
approval.

resolution certifying the existence of such vacancy by the Administrative
Trustees or, if there are more than two, a majority of the Administrative
Trustees shall be conclusive evidence of the existence of such vacancy. The
vacancy shall be filled with a Trustee appointed in accordance with Section 5.6.

SECTION 5.8         EFFECT OF VACANCIES.

                    The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to dissolve, liquidate or annul the Trust or to
terminate this Declaration. Whenever a vacancy in the number of Administrative
Trustees shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 5.6, the Administrative
Trustees in office, regardless of their number, shall have all the powers
granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Declaration.

SECTION 5.9         MEETINGS.

                    If there is more than one Administrative Trustee, meetings
of the Administrative Trustees shall be held from time to time upon the call of
any Administrative Trustee. Regular meetings of the Administrative Trustees may
be held at a time and place fixed by resolution of the Administrative Trustees.
Notice of any in-person meetings of the Administrative Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 24 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees or any committee thereof
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours

                                       33

before a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by
telephone) of an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, PROVIDED THAT, a Quorum is present, or without a meeting
by the unanimous written consent of the Administrative Trustees. In the event
there is only one Administrative Trustee, any and all action of such
Administrative Trustee shall be evidenced by a written consent of such
Administrative Trustee.

SECTION 5.10        DELEGATION OF POWER.

                    (a) Any Administrative Trustee may, by power of attorney
consistent with applicable law, delegate to any other natural person over the
age of 21 his or her power for the pur pose of executing any documents
contemplated in Section 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing.

                    (b) The Administrative Trustees shall have power to delegate
from time to time to such of their number or to officers of the Trust the doing
of such things and the execution of such instruments either in the name of the
Trust or the names of the Administrative Trustees or otherwise as the
Administrative Trustees may deem expedient, to the extent such delegation is not
prohibited by applicable law or contrary to the provisions of this Declaration.

SECTION 5.11        MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

                    Any Person into which the Property Trustee or the Delaware
Trustee or any Administrative Trustee that is not a natural person, as the case
may be, may be merged or converted or with which it may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Property Trustee or the Delaware Trustee, as the case may be, shall be a party,
or any Person succeeding to all or substantially all the corporate trust
business of the Property Trustee or the Delaware Trustee, as the case may be,
shall be the successor of the Property Trustee or the Delaware Trustee, as the
case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, provided such Person shall
be otherwise qualified and eligible under this Article and provided further that
such Person shall file an amendment to the Certificate of Trust with the
Delaware Secretary of State as contemplated in Section 5.6(h).

                                   ARTICLE VI
                                  DISTRIBUTIONS

SECTION 6.1         DISTRIBUTIONS.

                    Holders shall receive Distributions in accordance with the
applicable terms of the relevant Holder's Securities. If and to the extent that
the Debenture Issuer makes a payment of

                                       34

<PAGE>   41

interest (including Compounded Interest and Additional Sums), premium and/or
principal on the Debentures held by the Property Trustee or Liquidated Damages
or any other payments pursuant to the Registration Rights Agreement or
Liquidated Damages Agreement with respect to the Debentures held by the Property
Trustee (the amount of any such payment being a "Payment Amount"), the Property
Trustee shall and is directed, to the extent funds are available for that
purpose, to make a distribution (a "Distribution") of the Payment Amount to
Holders in accordance with the terms of the Securities.

                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1         GENERAL PROVISIONS REGARDING SECURITIES.

                    (a) The Administrative Trustees shall, on behalf of the
Trust, issue one class of capital securities representing undivided preferred
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "Series A Capital Securities") and one class of common
securities representing undivided common beneficial interests in the assets of
the Trust having such terms as are set forth in Annex I (the "Common
Securities"). The Administrative Trustees shall, on behalf of the Trust, issue
one class of capital securities representing undivided preferred beneficial
interests in the Trust having such terms as set forth in Annex I (the "Series B
Capital Securities") in exchange for the Series A Capital Securities accepted
for exchange in the Exchange Offer, which Series B Capital Securities shall not
bear the legends required by Section 9.2(i) unless the Holder of such Series A
Capital Securities is either (A) a broker-dealer who purchased such Series A
Capital Securities directly from the Trust for resale pursuant to Rule 144A or
any other available exemption under the Securities Act, (B) a Person
participating in the distribution of the Series A Capital Securities or (C) a
Person who is an Affiliate of the Sponsor or the Trust. The Trust shall issue no
securities or other interests in the assets of the Trust other than the Capital
Securities and the Common Securities.

                    (b) The consideration received by the Trust for the issuance
of the Securities shall constitute a contribution to the capital of the Trust
and shall not constitute a loan to the Trust.

                    (c) Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued and,
subject to the terms of this Declaration, fully paid and nonassessable.

                    (d) Every Person, by virtue of having become a Holder or a
Capital Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2         EXECUTION AND AUTHENTICATION.

                    (a) The Securities shall be signed on behalf of the Trust by
an Administrative Trustee. In case any Administrative Trustee of the Trust who
shall have signed any of the Securities shall cease to be such Administrative
Trustee before the Securities so signed shall be delivered by the Trust, such
Securities nevertheless may be delivered as though the Person who signed such

                                       35

<PAGE>   42

Securities had not ceased to be such Administrative Trustee; and any Securities
may be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Administrative Trustees of the Trust,
although at the date of the execution and delivery of this Declaration any such
person was not an Administrative Trustee.

                    (b) One Administrative Trustee shall sign the Capital
Securities for the Trust by manual or facsimile signature. Unless otherwise
determined by an Administrative Trustee on behalf of the Trust, an
Administrative Trustee shall sign the Common Securities for the Trust by manual
signature.

                    A Capital Security shall not be valid until authenticated by
the manual signature of an authorized signatory of the Property Trustee. The
signature shall be conclusive evidence that the Capital Security has been
authenticated under this Declaration. A Common Security shall be valid upon
execution by an Administrative Trustee without any act of the Property Trustee.

                    Upon a written order of the Trust signed by one
Administrative Trustee, the Property Trustee shall authenticate the Capital
Securities for original issue. The aggregate number of Capital Securities
outstanding at any time shall not exceed the number set forth in Annex I hereto
except as provided in Section 7.6.

                    The Property Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Capital Securities. An authenticating
agent may authenticate Capital Securities whenever the Property Trustee may do
so. Each reference in this Declaration to authentication by the Property Trustee
includes authentication by such agent. An authenticating agent has the same
rights as the Property Trustee hereunder with respect to the Sponsor or an
Affiliate.

SECTION 7.3         FORM AND DATING.

                    The Capital Securities shall be evidenced by one or more
certificates substantially in the form of Exhibit A-1, and the Common Securities
shall be evidenced by one or more certificates substantially in the form of
Exhibit A-2. The Property Trustee's certificate of authentication shall be
substantially in the form set forth in Exhibit A-1. Certificates representing
the Securities may be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to an Administrative Trustee, as
evidenced by the execution thereof. The Securities may have letters, "CUSIP" or
other numbers, notations or other marks of identification or designation and
such legends or endorsements required by law, stock exchange rule, agreements to
which the Trust is subject, if any, or usage, PROVIDED THAT, any such notation,
legend or endorsement is in a form acceptable to the Administrative Trustees,
as evidenced by their execution thereof. The Trust at the direction of the
Sponsor, shall furnish any such legend not contained in Exhibit A-1 to the
Property Trustee in writing. Each Capital Security shall be dated the date of
its authentication. The terms and provisions of the Securities set forth in
Annex I and the forms of Securities set forth in Exhibits A-1 and A-2 are part
of the terms of this Declaration and, to the extent applicable, the Property
Trustee and the Sponsor, by their execution and delivery of this Declaration,
expressly agree to such terms and provisions and to be bound thereby.

                    (a) GLOBAL CAPITAL SECURITY. Capital Securities offered and
sold to QIBs in reliance on Rule 144A, as provided in the Purchase Agreement,
shall be issued in the form of a single permanent global Capital Security in
definitive, fully registered form without distribution coupons with the
appropriate global legends and Restricted Securities Legend set forth in Exhibit
A-1 hereto (the "Global Capital Security"), which shall be deposited on behalf
of the purchasers of the Capital Securities represented thereby with the
Property Trustee, at its Corporate Trust Office, as custodian for the Clearing
Agency, and registered in the name of the Clearing Agency or a nominee of the
Clearing Agency, duly executed by the Trust and authenticated by the Property
Trustee as hereinafter provided. The number of Capital Securities represented by
the Global Capital Security may from time to time be increased or decreased by
adjustments made on the records of the Property Trustee and the Clearing Agency
or its nominee as hereinafter provided.

                    (b) BOOK-ENTRY PROVISIONS. This Section 7.3(b) shall apply
only to the Global Capital Security and such other Capital Securities in global
form as may be authorized by the Trust to be deposited with or on behalf of the
Clearing Agency.

                    An Administrative Trustee shall execute and the Property
Trustee shall, in accordance with this Section 7.3, authenticate and make
available for delivery initially a single Global Capital Security that (i) shall
be registered in the name of Cede & Co. or other nominee of such Clearing
Agency, and (ii) shall be delivered by the Property Trustee to such Clearing
Agency or pursuant to such Clearing Agency's written instructions or, if no such
written instructions are received by the Property Trustee, held by the Property
Trustee as custodian for the Clearing Agency.

                    Members of, or participants in, the Clearing Agency
("Participants") shall have no rights under this Declaration with respect to the
Global Capital Security held on their behalf by the Clearing Agency or by the
Property Trustee as the custodian of the Clearing Agency or under such Global
Capital Security, and the Clearing Agency may be treated by the Trust, the
Property Trustee and any agent of the Trust or the Property Trustee as the
absolute owner of such Global Capital Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Trust, the
Property Trustee or any agent of the Trust or the Property Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Clearing Agency or impair, as between the Clearing Agency and its
Participants, the operation of customary practices of such Clearing Agency
governing the exercise of the rights of a holder of a beneficial interest in the
Global Capital Security.

                    (c) DEFINITIVE CAPITAL SECURITIES. Except as provided in
Section 7.9 or 9.2(f)(i), owners of beneficial interests in the Global Capital
Security will not be entitled to receive physical delivery of certificated
Capital Securities ("Definitive Capital Securities"). Purchasers of Securities
who are "accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7)
under the Securities Act) and who are not QIBs will receive Capital Securities
in the form of individual certificates in definitive, fully registered form
without distribution coupons and with the Restricted Securities Legend set forth
in Exhibit A-1 hereto ("Restricted Definitive Capital Securities"); PROVIDED,
HOWEVER, that upon registration of transfer of such Restricted Definitive
Capital Securities to a QIB, such Restricted Definitive Capital Securities will,
unless the Global Capital Security has previously been exchanged, be exchanged
for an interest in the Global Capital Security pursuant to the

                                       37

<PAGE>   44

provisions of Section 9.2. Restricted Definitive Capital Securities will bear
the Restricted Securities Legend set forth on Exhibit A-1 unless removed in
accordance with this Section 7.3 or Section 9.2.

SECTION 7.4         REGISTRAR, PAYING AGENT AND EXCHANGE AGENT.

                    The Trust shall maintain in Wilmington, Delaware (i) an
office or agency where Capital Securities may be presented for registration of
transfer ("Registrar"), (ii) an office or agency where Capital Securities may be
presented for payment ("Paying Agent") and (iii) an office or agency where
Securities may be presented for exchange ("Exchange Agent"). The Registrar shall
keep a register of the Capital Securities and of their transfer. The Trust may
appoint the Registrar, the Paying Agent and the Exchange Agent and may appoint
one or more co-registrars, one or more additional paying agents and one or more
additional Exchange Agents in such other locations as it shall determine. The
term "Registrar" includes any additional registrar, the term "Paying Agent"
includes any additional paying agent and the term "Exchange Agent" includes any
additional Exchange Agent. The Trust may change any Paying Agent, Registrar,
co-registrar or Exchange Agent without prior notice to any Holder. The Paying
Agent shall be permitted to resign as Paying Agent upon 30 days' written notice
to the Property Trustee, the Administrative Trustees and the Sponsor. The Trust
shall notify the Property Trustee of the name and address of any Agent not a
party to this Declaration. If the Trust fails to appoint or maintain another
entity as Registrar, Paying Agent or Exchange Agent, the Property Trustee shall
act as such. The Trust or any of its Affiliates may act as Paying Agent,
Registrar, or Exchange Agent. The Trust shall act as Paying Agent, Registrar and
Exchange Agent for the Common Securities.

                    The Trust initially appoints the Property Trustee as
Registrar, Paying Agent and Exchange Agent for the Capital Securities.

SECTION 7.5         PAYING AGENT TO HOLD MONEY IN TRUST.

                    The Trust shall require each Paying Agent other than the
Property Trustee to agree in writing that the Paying Agent will hold in trust
for the benefit of Holders or the Property Trustee all money held by the Paying
Agent for the payment of liquidation amounts or Distributions, and will notify
the Property Trustee if there are insufficient funds for such purpose. While any
such insufficiency continues, the Property Trustee may require a Paying Agent to
pay all money held by it to the Property Trustee. The Trust at any time may
require a Paying Agent to pay all money held by it to the Property Trustee and
to account for any money disbursed by it. Upon payment over to the Property
Trustee, the Paying Agent (if other than the Trust or an Affiliate of the Trust)
shall have no further liability for the money. If the Trust or the Sponsor or an
Affiliate of the Trust or the Sponsor acts as Paying Agent, it shall segregate
and hold in a separate trust fund for the benefit of the Holders all money held
by it as Paying Agent.

SECTION 7.6         REPLACEMENT SECURITIES.

                    If a Holder claims that a Security owned by it has been
lost, destroyed or wrongfully taken or if such Security is mutilated and is
surrendered to the Trust or in the case of the Capital Securities to the
Property Trustee, an Administrative Trustee shall execute and the Property
Trustee shall authenticate and make available for delivery a replacement
Security if the Property

                                       38

<PAGE>   45

Trustee's requirements are met. An indemnity bond must be provided by the Holder
which, in the judgment of the Property Trustee, is sufficient to protect the
Trustees, the Sponsor, the Trust or any authenticating agent from any loss which
any of them may suffer if a Security is replaced. The Trust may charge such
Holder for its expenses in replacing a Security.

SECTION 7.7         OUTSTANDING CAPITAL SECURITIES.

                    The Capital Securities outstanding at any time are all the
Capital Securities authenticated by the Property Trustee except for those
canceled by it, those delivered to it for cancellation, and those described in
this Section as not outstanding.

                    If a Capital Security is replaced, paid or purchased
pursuant to Section 7.6 hereof, it ceases to be outstanding unless the Property
Trustee receives proof satisfactory to it that the replaced, paid or purchased
Capital Security is held by a bona fide purchaser.

                    If Capital Securities are considered paid in accordance with
the terms of this Declaration, they cease to be outstanding and Distributions on
them shall cease to accumulate.

                    A Capital Security does not cease to be outstanding because
one of the Trust, the Sponsor or an Affiliate of the Sponsor holds the Security.

SECTION 7.8         CAPITAL SECURITIES IN TREASURY.

                    In determining whether the Holders of the required amount of
Securities have concurred in any direction, waiver or consent, Capital
Securities owned by the Trust, the Sponsor or an Affiliate of the Sponsor, as
the case may be, shall be disregarded and deemed not to be outstanding, except
that for the purposes of determining whether the Property Trustee shall be fully
protected in relying on any such direction, waiver or consent, only Securities
which the Property Trustee actually knows are so owned shall be so disregarded.

SECTION 7.9         TEMPORARY SECURITIES.

                    (a) Until Definitive Capital Securities are ready for
delivery, the Trust may prepare and, in the case of the Capital Securities, the
Property Trustee shall authenticate temporary Securities. Temporary Securities
shall be substantially in the form of Definitive Capital Securities but may have
variations that the Trust considers appropriate for temporary Securities.
Without unreasonable delay, the Trust shall prepare and, in the case of the
Capital Securities, the Property Trustee shall authenticate Definitive Capital
Securities in exchange for temporary Securities.

                    (b) The Global Capital Security deposited with the Clearing
Agency or with the Property Trustee as custodian for the Clearing Agency
pursuant to Section 7.3 shall be transferred to the beneficial owners thereof in
the form of Definitive Capital Securities only if such transfer complies with
Section 9.2 and (i) the Clearing Agency notifies the Sponsor that it is
unwilling or unable to continue as Clearing Agency for such Global Capital
Security or if at any time such Clearing Agency ceases to be a "clearing agency"
registered under the Exchange Act, and, in each case, a clearing agency is not
appointed by the Sponsor within 90 days of receipt of such notice or

                                       39

<PAGE>   46

of becoming aware of such condition, (ii) a Default or an Event of Default has
occurred and is continuing, or (iii) the Trust at its sole discretion elects to
cause the issuance of Definitive Capital Securities.

                    (c) Any Global Capital Security that is transferable to the
beneficial owners thereof in the form of Definitive Capital Securities pursuant
to this Section 7.9 shall be surrendered by the Clearing Agency to the Property
Trustee to be so transferred, in whole or from time to time in part, without
charge, and the Property Trustee shall authenticate and make available for
delivery, upon such transfer of each portion of such Global Capital Security, an
equal aggregate liquidation amount of Capital Securities of authorized
denominations in the form of Definitive Capital Securities. Any portion of the
Global Capital Security transferred pursuant to this Section shall be registered
in such names as the Clearing Agency shall direct. Any Definitive Capital
Security delivered in exchange for an interest in the Restricted Global Capital
Security shall, except as otherwise provided by Sections 7.3 and 9.1, bear the
Restricted Securities Legend set forth in Exhibit A-l hereto.

                    (d) Subject to the provisions of Section 7.9(c), the Holder
of the Global Capital Security may grant proxies and otherwise authorize any
Person, including Participants and Persons that may hold interests through
Participants, to take any action which such Holder is entitled to take under
this Declaration or the Securities.

                    (e) In the event of the occurrence of any of the events
specified in Section 7.9(b), the Trust will promptly make available to the
Property Trustee a reasonable supply of certificated Capital Securities in
fully registered form without distribution coupons.

SECTION 7.10        CANCELLATION.

                    The Trust at any time may deliver Capital Securities to the
Property Trustee for cancellation. The Registrar, Paying Agent and Exchange
Agent shall forward to the Property Trustee any Capital Securities surrendered
to them for registration of transfer, redemption, exchange or payment. The
Property Trustee shall promptly cancel all Capital Securities surrendered for
registration of transfer, redemption, exchange, payment, replacement or
cancellation and shall dispose of canceled Capital Securities in accordance with
its customary procedures unless the Trust otherwise directs. The Trust may not
issue new Capital Securities to replace Capital Securities that it has paid or
that have been delivered to the Property Trustee for cancellation or that any
Holder has exchanged.

SECTION 7.11        CUSIP NUMBERS.

                    The Trust in issuing the Capital Securities may use "CUSIP"
numbers (if then generally in use), and, if so, the Property Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders of Capital
Securities; PROVIDED THAT, any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Capital
Securities or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Capital
Securities, and any such redemption shall not be

                                       40

<PAGE>   47

affected by any defect in or omission of such numbers. The Sponsor will promptly
notify the Property Trustee of any change in the CUSIP numbers.

                                  ARTICLE VIII
                              DISSOLUTION OF TRUST

SECTION 8.1         DISSOLUTION OF TRUST.

                    (a) The Trust shall automatically dissolve:

                        (i)   upon the bankruptcy of the Sponsor;

                        (ii)  upon the filing of a certificate of dissolution
                    or liquidation or its equivalent with respect to the
                    Sponsor; or the revocation of the Sponsor's charter and the
                    expiration of 90 days after the date of revocation without
                    a reinstatement thereof;

                        (iii) following the distribution of a Like Amount of
                    the Debentures to the Holders, PROVIDED THAT, the Property
                    Trustee has received written notice from the Sponsor
                    directing the Property Trustee to dissolve the Trust (which
                    direction is optional, and except as otherwise expressly
                    provided below, within the discretion of the Sponsor), and
                    PROVIDED, FURTHER, that such direction and such
                    distribution is conditioned on (a) the receipt by the

                    Administrative Trustees of an opinion of independent tax

                    on public or private rulings of the Internal Revenue
                    Service, to the effect that the Holders of the Capital
                    Securities will not recognize any gain or loss for United
                    States federal income tax purposes as a result of the
                    dissolution of the Trust and the distribution of
                    Debentures;

                        (iv)  upon the entry of a decree of judicial

                    jurisdiction;

                    accordance with the terms of the Securities;

                        (vi)  upon the redemption or repayment of the

by filing a certificate of cancellation with the Secretary of State of the State

                    (c) The provisions of Section 3.9 and Article X shall
survive the dissolution and termination of the Trust.

                                   ARTICLE IX
                              TRANSFER OF INTERESTS

SECTION 9.1         TRANSFER OF SECURITIES.

                    (a) Securities may only be transferred, in whole or in part,
in accordance with the terms and conditions set forth in this Declaration and in
accordance with the terms of the Securities. To the fullest extent permitted by
law, any transfer or purported transfer of any Security not made in accordance
with this Declaration shall be null and void.

                    (b) Subject to this Article IX, Capital Securities may only
be transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration. To the fullest extent permitted by law, any
transfer or purported transfer of any Security not made in accordance with this
Declaration shall be null and void.

                    (c) For so long as the Securities remain outstanding, the
Sponsor agrees (i) not to transfer ownership of the Common Securities of the
Trust, provided that any permitted successor of the Sponsor under the Indenture
may succeed to the Sponsor's ownership of the Common Securities, (ii) not to
cause, as Sponsor of the Trust, or to permit, as Holder of the Common
Securities, the dissolution, winding-up or liquidation of the Trust, except as
provided in this Declaration and (iii) to use its best efforts to cause the
Trust (a) to remain a business trust, except in connection with the distribution
of Debentures to the Holders in liquidation of the Trust, the redemption of all
of the Securities, or certain mergers, consolidations or amalgamations, each as
permitted by this Declaration, and (b) to otherwise continue to be classified as
a grantor trust for United States federal income tax purposes.

                    (d) The Registrar shall provide for the registration of
Capital Securities and of the transfer of Capital Securities, which will be
effected without charge but only upon payment (with such indemnity as the
Registrar may require) in respect of any tax or other governmental charges that
may be imposed in relation to it. Upon surrender for registration of transfer of
any Capital Securities, an Administrative Trustee shall cause one or more new
Capital Securities to be issued in the name of the designated transferee or
transferees. Every Capital Security surrendered for registration of transfer
shall be accompanied by a written instrument of transfer in form satisfactory to
the Registrar duly executed by the Holder or such Holder's attorney duly
authorized in writing. Each Capital Security surrendered for registration of
transfer shall be delivered to the Registrar and canceled in accordance with
Section 7.10. A transferee of a Capital Security shall be entitled to the rights
and subject to the obligations of a Holder hereunder upon the receipt by such
transferee of a Capital Security. By acceptance of a Capital Security or any
interest therein, each transferee shall be deemed to have agreed to be bound by
this Declaration.

SECTION 9.2         TRANSFER PROCEDURES AND RESTRICTIONS.

                    (a) GENERAL. Except as otherwise provided in Section 9.2(b),
if Capital Securities are issued upon the transfer, exchange or replacement of
Capital Securities bearing the Restricted Securities Legend set forth in
Exhibit A-1 hereto, or if a request is made to remove such Restricted Securities
Legend on Capital Securities, the Capital Securities so issued shall bear the
Restricted Securities Legend, or the Restricted Securities Legend shall not be
removed, as the case may be, unless there is delivered to the Trust and the
Property Trustee such satisfactory evidence, which shall include an Opinion of
Counsel, as may be reasonably required by the Trust and the Property Trustee,
that neither the Restricted Securities Legend nor the restrictions on transfer
set forth therein are required to ensure that transfers thereof are made
pursuant to an exception from the registration requirements of the Securities
Act or, with respect to Restricted Capital Securities, that such Securities are
not "restricted" within the meaning of Rule 144. Upon provision of such
satisfactory evidence, the Property Trustee, at the written direction of an
Administrative Trustee on behalf of the Trust, shall authenticate and deliver
Capital Securities that do not bear the legend.

                    (b) TRANSFERS AFTER EFFECTIVENESS OF A REGISTRATION
STATEMENT. After the effectiveness of a Registration Statement with respect to
any Capital Securities, all requirements pertaining to legends on such Capital
Securities will cease to apply (other than the legend requiring that transfers
of Capital Securities be made in blocks having an aggregate liquidation amount
of not less than $100,000 (100 Capital Securities) and multiples of $1,000 in
excess thereof), and beneficial interests in the Global Capital Security without
legends will be available to transferees of such Capital Securities, upon
exchange of the transferring Holder's Restricted Definitive Capital Security or
directions to transfer such Holder's beneficial interest in the Global Capital
Security, as the case may be. No such transfer or exchange of a Restricted
Definitive Capital Security or of an interest in the Global Capital Security
shall be effective unless the transferor delivers to the Property Trustee a
certificate in a form substantially similar to that attached hereto as the form
of "Assignment" in Exhibit A-1. Except as otherwise provided in Section 9.2(m),
after the effectiveness of a Registration Statement, an Administrative Trustee
on behalf of the Trust shall issue and the Property Trustee, upon a written
order of the Trust signed by one Administrative Trustee, shall authenticate a
Global Capital Security without the Restricted Securities Legend (the
"Unrestricted Global Capital Security") to deposit with the Clearing Agency to
evidence transfers of beneficial interests from the Global Capital Security and
Restricted Definitive Capital Securities.

                    (c) TRANSFER AND EXCHANGE OF DEFINITIVE CAPITAL SECURITIES.
When Definitive Capital Securities are presented to the Registrar or
co-registrar:

                    (x) to register the transfer of such Definitive Capital
              Securities; or

                    (y) to exchange such Definitive Capital Securities which
              became mutilated, destroyed, defaced, stolen or lost, for an equal
              number of Definitive Capital Securities, the Registrar or
              co-registrar shall register the transfer or make the exchange as
              requested if its reasonable requirements for such transaction are
              met;

              PROVIDED, HOWEVER, that the Definitive Capital Securities
              surrendered for registration of transfer or exchange:

                                       43

<PAGE>   50

                             (i) shall be duly endorsed or accompanied by a
                      written instrument of transfer in form reasonably
                      satisfactory to the Trust and the Registrar or
                      co-registrar, duly executed by the Holder thereof or his
                      attorney duly authorized in writing; and

                             (ii) in the case of Definitive Capital Securities
                      that are Restricted Definitive Capital Securities:

                             (A) if such Restricted Capital Securities are being
                             delivered to the Registrar by a Holder for
                             registration in the name of such Holder, without
                             transfer, certification(s) from such Holder to that
                             effect; or

                             (B) if such Restricted Capital Securities are being
                             transferred: (i) certification(s) in a form
                             substantially similar to that attached hereto as
                             the form of "Assignment" in Exhibit A-1, and (ii)
                             if the Trust or Registrar so requests, evidence
                             reasonably satisfactory to them as to the
                             compliance with the restrictions set forth in the
                             Restricted Securities Legend.

                    (d) RESTRICTIONS ON TRANSFER OF A DEFINITIVE CAPITAL
SECURITY FOR A BENEFICIAL INTEREST IN THE GLOBAL CAPITAL SECURITY. A Definitive
Capital Security may not be exchanged for a beneficial interest in the Global
Capital Security except upon satisfaction of the requirements set forth below.
Upon receipt by the Property Trustee of a Definitive Capital Security, duly
endorsed or accompanied by appropriate instruments of transfer, in form
satisfactory to the Property Trustee, together with:

                        (i) if such Definitive Capital Security is a
                    Restricted Capital Security, certification(s) in a form
                    substantially similar to that attached hereto as the form
                    of "Assignment" in Exhibit A-1; and

                        (ii) whether or not such Definitive Capital
                    Security is a Restricted Capital Security, written
                    instructions directing the Property Trustee to make, or to
                    direct the Clearing Agency to make, an adjustment on its
                    books and records with respect to the Global Capital
                    Security to reflect an increase in the number of the
                    Capital Securities represented by such Global Capital
                    Security,

then the Property Trustee shall cancel such Definitive Capital Security and
cause, or direct the Clearing Agency to cause, the aggregate number of Capital
Securities represented by the Global Capital Security to be increased
accordingly. If the Global Capital Security is not then outstanding, an
Administrative Trustee on behalf of the Trust shall issue and the Property
Trustee shall authenticate, upon written order of any Administrative Trustee, a
new Global Capital Security representing an appropriate number of Capital
Securities.

                    (e) TRANSFER AND EXCHANGE OF THE GLOBAL CAPITAL SECURITY.
Subject to Section 9.2(f), the transfer and exchange of the Global Capital
Security or beneficial interests therein shall be effected through the Clearing
Agency in accordance with this Declaration (including applicable restrictions on
transfer set forth herein, if any) and the procedures of the Clearing Agency
therefor.

                    (f) TRANSFER OF A BENEFICIAL INTEREST IN THE GLOBAL CAPITAL
SECURITY FOR A DEFINITIVE CAPITAL SECURITY.

                        (i) Any Person having a beneficial interest in the
                    Global Capital Security may upon request, but only upon 20
                    days prior notice to the Property Trustee, and if
                    accompanied by the information specified below, exchange
                    such beneficial interest for a Definitive Capital Security
                    representing the same number of Capital Securities. Upon
                    receipt by the Property Trustee from the Clearing Agency
                    or its nominee on behalf of any Person having a beneficial
                    interest in the Global Capital Security of written
                    instructions or such other form of instructions as is
                    customary for the Clearing Agency or the Person designated
                    by the Clearing Agency as having such a beneficial
                    interest in a Restricted Capital Security and
                    certification(s) from the transferor in a form
                    substantially similar to that attached hereto as the form
                    of "Assignment" in Exhibit A-1, which may be submitted by
                    facsimile, then the Property Trustee will cause the
                    aggregate number of Capital Securities represented by the
                    Global Capital Security to be reduced on its books and
                    records and, following such reduction, the Trust will
                    execute and the Property Trustee will authenticate and
                    make available for delivery to the transferee a Definitive
                    Capital Security.

                        (ii) Definitive Capital Securities issued in
                    exchange for a beneficial interest in the Global Capital
                    Security pursuant to this Section 9.2(f) shall be
                    registered in such names and in such authorized
                    denominations as the Clearing Agency, pursuant to
                    instructions from its Clearing Agency Participants or
                    indirect participants or otherwise, shall instruct the
                    Property Trustee in writing. The Property Trustee shall
                    deliver such Capital Securities to the Persons in whose
                    names such Capital Securities are so registered in
                    accordance with such instructions of the Clearing Agency.

                    (g) RESTRICTIONS ON TRANSFER AND EXCHANGE OF THE GLOBAL
CAPITAL SECURITY. Notwithstanding any other provisions of this Declaration
(other than the provisions set forth in subsection (h) of this Section 9.2), the
Global Capital Security may not be transferred as a whole except by the Clearing
Agency to a nominee of the Clearing Agency or another nominee of the Clearing
Agency or by the Clearing Agency or any such nominee to a successor Clearing
Agency or a nominee of such successor Clearing Agency.

                    (h) AUTHENTICATION OF DEFINITIVE CAPITAL SECURITIES. If at
any time:

                        (i)   a Default or an Event of Default has occurred
                    and is continuing,

                        (ii)  the Trust, in its sole discretion, notifies
                    the Property Trustee in writing that it elects to cause
                    the issuance of Definitive Capital Securities under this
                    Declaration, or

                        (iii) the Clearing Agency notifies the Sponsor that
                    it is unwilling or unable to continue as Clearing Agency
                    for such Global Capital Security or if at any time

                                       45

<PAGE>   52

                    such Clearing Agency ceases to be a "clearing agency"
                    registered under the Exchange Act, and, in each case, a
                    clearing agency is not appointed by the Sponsor within 90
                    days of receipt of such notice or of becoming aware of
                    such condition,

then an Administrative Trustee on behalf of the Trust will execute, and the
Property Trustee, upon receipt of a written order of the Trust signed by one
Administrative Trustee requesting the authentication and delivery of Definitive
Capital Securities to the Persons designated by the Trust, will authenticate and
make available for delivery Definitive Capital Securities, equal in number to
the number of Capital Securities represented by the Global Capital Security, in
exchange for such Global Capital Security.

                    (i) LEGEND.

                        (i) Except as permitted by the following paragraph
                    (ii), each Capital Security Certificate evidencing the
                    Global Capital Security and each Definitive Capital
                    Security (and all Capital Securities issued in exchange
                    therefor or substitution thereof) shall bear a legend (the

                    SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO,
                    REGISTRATION.

                    PLAN, OR ANY OTHER PERSON OR ENTITY USING THE ASSETS OF
                    ANY EMPLOYEE BENEFIT PLAN OR PLAN TO FINANCE SUCH
                    PURCHASE, OR (ii) SUCH PURCHASE WILL NOT RESULT IN A
                    PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR
                    SECTION 4975 OF THE CODE FOR WHICH THERE IS NO APPLICABLE
                    STATUTORY OR ADMINISTRATIVE EXEMPTION.

In all circumstances, each Capital Security Certificate shall bear the following

                    SUCH PURPORTED TRANSFEREE SHALL BE DEEMED NOT TO BE THE
                    HOLDER OF SUCH CAPITAL SECURITIES FOR ANY PURPOSE,
                    INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF
                    DISTRIBUTIONS ON SUCH CAPITAL SECURITIES, AND SUCH
                    PURPORTED TRANSFEREE SHALL BE DEEMED TO HAVE NO INTEREST
                    WHATSOEVER IN SUCH CAPITAL SECURITIES.

                        (ii) Upon any sale or transfer of a Restricted
                    Capital Security (including any Restricted Capital
                    Security represented by the Global Capital Security)
                    pursuant to an effective registration statement under the
                    Securities Act or pursuant to Rule 144:

                        (A) in the case of any Restricted Capital Security that
                        is a Definitive Capital Security, the Registrar shall
                        permit the Holder thereof to exchange such Restricted
                        Capital Security for a Definitive Capital Security that
                        does not bear the Restricted Securities Legend and
                        rescind any restriction on the transfer of such
                        Restricted Capital Security; and

                        (B) in the case of any Restricted Capital Security that
                        is represented by the Global Capital Security, the
                        Registrar shall permit the Holder of such Global Capital
                        Security to exchange such Global Capital Security for
                        another Global Capital Security that does not bear the
                        Restricted Securities Legend.

                    (j) CANCELLATION OR ADJUSTMENT OF GLOBAL CAPITAL SECURITY.
At such time as all beneficial interests in the Global Capital Security have
either been exchanged for Definitive Capital Securities to the extent permitted
by this Declaration or redeemed, repurchased or canceled in accordance with the
terms of this Declaration, such Global Capital Security shall be returned to the
Clearing Agency for cancellation or retained and canceled by the Property
Trustee. At any time prior to such cancellation, if any beneficial interest in
the Global Capital Security is exchanged for Definitive Capital Securities,
Capital Securities represented by such Global Capital Security shall be reduced
and an adjustment shall be made on the books and records of the Property Trustee
and the Clearing Agency or its nominee to reflect such reduction.

                    (k) OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF
CAPITAL SECURITIES.

                        (i)  To permit registrations of transfers and
                    exchanges, the Trust shall execute and the Property Trustee
                    shall authenticate Definitive Capital Securities and the
                    Global Capital Security at the Registrar's or
                    co-registrar's request in accordance with the terms of this
                    Declaration.

                        (ii) Registrations of transfers or exchanges will be
                    effected without charge, but only upon payment (with such
                    indemnity as the Trust or the Sponsor

                    may require) in respect of any tax or other governmental
                    charge that may be imposed in relation to it.

                        (iii) The Registrar or co-registrar shall not be
                    required to register the transfer of or exchange of (a)
                    Capital Securities during a period beginning at the opening
                    of business 15 days before the day of mailing of a notice
                    of redemption or any notice of selection of Capital
                    Securities for redemption and ending at the close of
                    business on the day of such mailing or (b) any Capital
                    Security so selected for redemption in whole or in part,
                    except the unredeemed portion of any Capital Security being
                    redeemed in part.

                        (iv) Prior to the due presentation for registration
                    of transfer of any Capital Security, the Trust, the
                    Property Trustee, the Paying Agent, the Registrar or any
                    co-registrar may deem and treat the Person in whose name a
                    Capital Security is registered as the absolute owner of
                    such Capital Security for the purpose of receiving
                    Distributions on such Capital Security and for all other
                    purposes whatsoever, and none of the Trust, the Property
                    Trustee, the Paying Agent, the Registrar or any
                    co-registrar shall be affected by notice to the contrary.

                        (v) All Capital Securities issued upon any
                    registration of transfer or exchange pursuant to the terms
                    of this Declaration shall evidence the same security and
                    shall be entitled to the same benefits under this
                    Declaration as the Capital Securities surrendered upon
                    such registration of transfer or exchange.

                    (l) NO OBLIGATION OF THE PROPERTY TRUSTEE.

                        (i) The Property Trustee shall have no
                    responsibility or obligation to any Capital Security
                    Beneficial Owner, a Participant in the Clearing Agency or
                    other Person with respect to the accuracy of the records of
                    the Clearing Agency or its nominee or of any Participant
                    thereof, with respect to any ownership interest in the
                    Capital Securities or with respect to the delivery to any
                    Participant, beneficial owner or other Person (other than
                    the Clearing Agency) of any notice (including any notice of
                    redemption) or the payment of any amount, under or with
                    respect to such Capital Securities. All notices and
                    communications to be given to the Holders and all payments
                    to be made to Holders under the Capital Securities shall be
                    given or made only to or upon the order of the registered
                    Holders (which shall be the Clearing Agency or its nominee
                    in the case of the Global Capital Security). The rights of
                    Capital Security Beneficial Owners shall be exercised only
                    through the Clearing Agency subject to the applicable rules
                    and procedures of the Clearing Agency. The Property Trustee
                    may conclusively rely and shall be fully protected in
                    relying upon information furnished by the Clearing Agency
                    or any agent thereof with respect to its Participants and
                    any Capital Security Beneficial Owners.

                        (ii) The Property Trustee and the Registrar shall
                    have no obligation or duty to monitor, determine or
                    inquire as to compliance with any restrictions on

                                       50

<PAGE>   57

                    transfer imposed under this Declaration or under
                    applicable law with respect to any transfer of any
                    interest in any Capital Security (including any transfers
                    between or among Clearing Agency Participants or Capital
                    Security Beneficial Owners) other than to require delivery
                    of such certificates and other documentation or evidence
                    as are expressly required by, and to do so if and when
                    expressly required by, the terms of this Declaration, and
                    to examine the same to determine substantial compliance as
                    to form with the express requirements hereof.

                    (m) EXCHANGE OF SERIES A CAPITAL SECURITIES FOR SERIES B
CAPITAL SECURITIES. The Series A Capital Securities shall be exchanged for
Series B Capital Securities pursuant to the terms of the Exchange Offer if the
following conditions are satisfied:

                    The Sponsor shall present the Property Trustee with an
Officers' Certificate certifying the following:

                    (A) upon issuance of the Series B Capital Securities, the
                    transactions contemplated by the Exchange Offer have been
                    consummated; and

                    (B) the number of Series A Capital Securities properly
                    tendered in the Exchange Offer that are represented by the
                    Global Capital Security and the number of Series A Capital
                    Securities properly tendered in the Exchange Offer that are
                    represented by Definitive Capital Securities, the name of
                    each Holder of such Definitive Capital Securities, the
                    liquidation amount of Capital Securities properly tendered
                    in the Exchange Offer by each such Holder and the name and
                    address to which Definitive Capital Securities for Series B
                    Capital Securities shall be registered and sent for each
                    such Holder.

                    The Property Trustee, upon receipt of (i) such Officers'
Certificate, (ii) an Opinion of Counsel (x) to the effect that the Series B
Capital Securities and the Series B Capital Securities Guarantee have been
registered under Section 5 of the Securities Act and that this Declaration and
the Series B Capital Securities Guarantee have been qualified under the Trust
Indenture Act and (y) with respect to the matters set forth in Section 3(q) of
the Registration Rights Agreement, shall authenticate (A) the Global Capital
Security, executed and delivered by the Trust to the Property Trustee, for
Series B Capital Securities in aggregate liquidation amount equal to the
aggregate liquidation amount of Series A Capital Securities represented by the
Global Capital Security indicated in such Officers' Certificate as having been
properly tendered and (B) Definitive Capital Securities, executed and delivered
by the Trust to the Property Trustee, representing Series B Capital Securities
registered in the names and in the liquidation amounts indicated in such
Officers' Certificate.

                    If, upon consummation of the Exchange Offer, less than all
the outstanding Series A Capital Securities shall have been properly tendered
and not withdrawn, the Property Trustee shall make an endorsement on the Global
Capital Security for Series A Capital Securities indicating the

                                       51

<PAGE>   58

reduction in the number and aggregate liquidation amount represented thereby as
a result of the Exchange Offer.

                    The Trust shall deliver such authenticated Definitive
Capital Securities for Series B Capital Securities to the Holders thereof as
indicated in such Officers' Certificate.

                    (n) MINIMUM TRANSFERS. Series A Capital Securities and, if
and when issued, Series B Capital Securities may only be transferred in minimum
blocks of $100,000 aggregate liquidation amount (100 Capital Securities) and
multiples of $1,000 in excess thereof. Any attempted transfer of Series A
Capital Securities or Series B Capital Securities in a block having an aggregate
liquidation amount of less than $100,000 shall be deemed to be voided and of no
legal effect whatsoever. Any such purported transferee shall be deemed not to be
a Holder of such Series A Capital Securities or Series B Capital Securities for
any purpose, including, but not limited to, the receipt of Distributions on such
Capital Securities, and such purported transferee shall be deemed to have no
interest whatsoever in such Capital Securities.

SECTION 9.3         DEEMED SECURITY HOLDERS.

                      The Trustees may treat the Person in whose name any
Security shall be registered on the books and records of the Trust as the sole
owner and Holder of such Security for purposes of receiving Distributions and
for all other purposes whatsoever and, accordingly, shall not be bound to
recognize any equitable or other claim to or interest in such Security on the
part of any Person, whether or not the Trust shall have actual or other notice
thereof.

SECTION 9.4         BOOK-ENTRY INTERESTS.

                    The Global Capital Security shall initially be registered on
the books and records of the Trust in the name of Cede & Co., the nominee of the
Clearing Agency and no Capital Security Beneficial Owner will receive physical
delivery of a definitive Capital Security certificate (a "Capital Security
Certificate") representing such Capital Security Beneficial Owner's interests in
such Global Capital Security, except as provided in Section 9.2 and Section 7.9.
Unless and until Definitive Capital Securities have been issued to the Capital
Security Beneficial Owners pursuant to Section 9.2 or Section 7.9:

                    (a) the provisions of this Section 9.4 shall be in full
force and effect;

                    (b) the Trust and the Trustees shall be entitled to deal
with the Clearing Agency for all purposes of this Declaration (including the
payment of Distributions on the Global Capital Security and receiving approvals,
votes or consents hereunder) as the sole Holder of the Global Capital Security
and shall have no obligation to the Capital Security Beneficial Owners;

                    (c) to the extent that the provisions of this Section 9.4
conflict with any other provisions of this Declaration, the provisions of this
Section 9.4 shall control; and

                    (d) the rights of the Capital Security Beneficial Owners
shall be exercised only through the Clearing Agency and shall be limited to
those established by law and agreements

                                       52

<PAGE>   59

between such Capital Security Beneficial Owners and the Clearing Agency and/or
the Clearing Agency Participants, and the Clearing Agency shall receive and
transmit payments of Distributions on the Global Capital Security to such
Clearing Agency Participants; PROVIDED, HOWEVER, that solely for the purposes of
determining whether the Holders of the requisite amount of Capital Securities
have voted on any matter provided for in this Declaration, the Trustees, with
respect to the Global Capital Security, may conclusively rely on, and shall be
protected in relying on, any written instrument (including a proxy) delivered to
the Trustees by the Clearing Agency setting forth the Capital Security
Beneficial Owners' votes or assigning the right to vote on any matter to any
other Persons either in whole or in part; and the Clearing Agency will also make
book-entry transfers among the Clearing Agency Participants.

SECTION 9.5         NOTICES TO CLEARING AGENCY.

                    Whenever a notice or other communication to the Capital
Security Holders is required to be given by a Trustee under this Declaration,
such Trustee shall give all such notices and communications specified herein to
be given to the Holder of the Global Capital Security to the Clearing Agency and
shall have no notice obligations to the Capital Security Beneficial Owners.

SECTION 9.6         APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

                    If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Capital Securities, the Administrative
Trustees may, in their sole discretion, appoint a successor Clearing Agency with
respect to such Capital Securities.

                    (a) Except as expressly set forth in this Declaration, the
Securities Guarantees and the terms of the Securities, the Sponsor shall not be:

                        (i) personally liable for the return of any portion
                    of the capital contributions (or any return thereon) of
                    the Holders which shall be made solely from assets of the
                    Trust; and

                        (ii) required to pay to the Trust or to any Holder any
                    deficit upon dissolution of the Trust or otherwise.

                    (b) The Sponsor shall be liable for all of the debts and
obligations of the Trust (other than in respect of the Securities) to the extent
not satisfied out of the Trust's assets.

                    (c) Pursuant to section 3803(a) of the Business Trust Act,
the  Holders shall be entitled to the same limitation of personal liability
extended to stockholders of private corporations for profit organized under the
General Corporation Law of the State of Delaware.

SECTION 10.2        EXCULPATION.

                    (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or in
the case of the Property Trustee or the Delaware Trustee, negligence) or willful
misconduct with respect to such acts or omissions.

                    (b) An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Trust and upon such information,
opinions, reports or statements presented to the Trust by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders might properly be paid.

SECTION 10.3        FIDUCIARY DUTY.

                    (a) To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Trust or to any other Covered Person, an Indemnified Person acting under
this Declaration shall not be liable to the Trust or to any other Covered Person
for its good faith reliance on the provisions of this Declaration. The
provisions of this Declaration, to the extent that they restrict the duties and
liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person.

                    (b) Unless otherwise expressly provided herein:

                        (i) whenever a conflict of interest exists or arises
                    between any Covered Person and any Indemnified Person, or

                        (ii) whenever this Declaration or any other
                    agreement contemplated herein or therein provides that an
                    Indemnified Person shall act in a manner that is, or
                    provides terms that are, fair and reasonable to the Trust
                    or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this

                                       54

<PAGE>   61

Declaration or any other agreement contemplated herein or of any duty or
obligation of the Indemnified Person at law or in equity or otherwise.

                    (c) Whenever in this Declaration an Indemnified Person is
permitted or required to make a decision:

                        (i)  in its "discretion" or under a grant of similar
                    authority, the Indemnified Person shall be entitled to
                    consider such interests and factors as it desires,
                    including its own interests, and shall have no duty or
                    obligation to give any consideration to any interest of or
                    factors affecting the Trust or any other Person; or

                        (ii) in its "good faith" or under another express
                    standard, the Indemnified Person shall act under such
                    express standard and shall not be subject to any other or
                    different standard imposed by this Declaration or by
                    applicable law.

SECTION 10.4        INDEMNIFICATION.

                    (a) (i)  The Sponsor shall indemnify, to the full extent
permitted by law, any Company Indemnified Person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Trust) by reason of the fact
that he is or was a Company Indemnified Person, against expenses (including
attorneys' fees and expenses), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Trust, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the Company
Indemnified Person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the Trust, and, with
respect to any criminal action or proceeding, had reasonable cause to believe
that his conduct was unlawful.

                        (ii) The Sponsor shall indemnify, to the full extent
permitted by law, any Company Indemnified Person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Trust to procure a judgment in its favor by
reason of the fact that he is or was a Company Indemnified Person against
expenses (including attorneys' fees and expenses) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Trust and except that no such
indemnification shall be made in respect of any claim, issue or matter as to
which such Company Indemnified Person shall have been adjudged to be liable to
the Trust unless and only to the extent that the Court of Chancery of Delaware
or the court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such Person is fairly and reasonably entitled to
indemnity for such expenses which such Court of Chancery or such other court
shall deem proper.

                        (iii) To the extent that a Company Indemnified Person
shall be successful on the merits or otherwise (including dismissal of an action
without prejudice or the settlement of an action without admission of liability)
in defense of any action, suit or proceeding referred to in paragraphs (i) and
(ii) of this Section 10.4(a), or in defense of any claim, issue or matter
therein, he shall be indemnified, to the full extent permitted by law, against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

                        (iv)  Any indemnification under paragraphs (i) and (ii)
of this Section 10.4(a) (unless ordered by a court) shall be made by the Sponsor
only as authorized in the specific case upon a determination that
indemnification of the Company Indemnified Person is proper in the circumstances
because he has met the applicable standard of conduct set forth in paragraphs
(i) and (ii). Such determination shall be made (1) by the Administrative
Trustees by a majority vote of a Quorum consisting of such Administrative
Trustees who were not parties to such action, suit or proceeding, (2) if such a
Quorum is not obtainable, or, even if obtainable, if a Quorum of disinterested
Administrative Trustees so directs, by independent legal counsel in a written
opinion, or (3) by the Common Security Holder of the Trust.

                        (v) Expenses (including attorneys' fees and expenses)
incurred by a Company Indemnified Person in defending a civil, criminal,
administrative or investigative action, suit or proceeding referred to in
paragraphs (i) and (ii) of this Section 10.4(a) shall be paid by the Sponsor in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such Company Indemnified Person to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Sponsor as authorized in this Section 10.4(a).
Notwithstanding the foregoing, no advance shall be made by the Sponsor if a
determination is reasonably and promptly made (i) by the Administrative Trustees
by a majority vote of a Quorum of disinterested Administrative Trustees, (ii) if
such a Quorum is not obtainable, or, even if obtainable, if a Quorum of
disinterested Administrative Trustees so directs, by independent legal counsel
in a written opinion or (iii) by the Common Security Holder of the Trust, that,
based upon the facts known to the Administrative Trustees, counsel or the Common
Security Holder at the time such determination is made, such Company Indemnified
Person acted in bad faith or in a manner that the Common Security Holder did not
believe to be in, or believed was opposed to, the best interests of the Trust,
or, with respect to any criminal proceeding, that such Company Indemnified
Person believed or had reasonable cause to believe his conduct was unlawful. In
no event shall any advance be made in instances where the Administrative
Trustees, independent legal counsel or Common Security Holder reasonably
determine that a Company Indemnified Person deliberately breached his duty to
the Trust or its Common or Capital Security Holders.

                        (vi)  The indemnification and advancement of expenses
provided by, or granted pursuant to, the other paragraphs of this Section
10.4(a) shall not be deemed exclusive of any other rights to which those seeking
indemnification and advancement of expenses may be entitled under any agreement,
vote of stockholders or disinterested directors of the Sponsor or Capital
Security Holders of the Trust or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office. All
rights to indemnification under this Section 10.4(a) shall be deemed to be
provided by a contract between the Sponsor and each Company Indemnified Person
who serves in such capacity at any time while this Section 10.4(a) is

                                       56

<PAGE>   63

in effect. Any repeal or modification of this Section 10.4(a) shall not affect
any rights or obligations then existing.

                        (vii) The Sponsor or the Trust may purchase and maintain
insurance on behalf of any person who is or was a Company Indemnified Person
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the Debenture
Issuer would have the power to indemnify him against such liability under the
provisions of this Section 10.4(a).

                        (viii) For purposes of this Section 10.4(a), references
to "the Trust" shall include, in addition to the resulting or surviving entity,
any constituent entity (including any constituent of a constituent) absorbed in
a consolidation or merger, so that any person who is or was a director, trustee,
officer or employee of such constituent entity, or is or was serving at the
request of such constituent entity as a director, trustee, officer, employee or
agent of another entity, shall stand in the same position under the provisions
of this Section 10.4(a) with respect to the resulting or surviving entity as he
would have with respect to such constituent entity if its separate existence had
continued.

                        (ix) The indemnification and advancement of expenses
provided by, or granted pursuant to, this Section 10.4(a) shall, unless
otherwise provided when authorized or ratified, continue as to a Person who has
ceased to be a Company Indemnified Person and shall inure to the benefit of the
heirs, executors and administrators of such a Person.

                    (b) The Sponsor agrees to indemnify the (i) Property
Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Property Trustee
or the Delaware Trustee, and (iv) any officers, directors, shareholders,
members, partners, employees, representatives, custodians, nominees or agents of
the Property Trustee or the Delaware Trustee (each of the Persons in (i) through
(iv), including the Property Trustee and the Delaware Trustee in their
respective individual capacities, being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any and all loss, liability, damage, action, suit, claim or expense including
taxes (other than taxes based on the income of such Fiduciary Indemnified
Person) of any kind and nature whatsoever incurred without negligence or bad
faith on the part of such Fiduciary Indemnified Person, arising out of or in
connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses (including reasonable legal fees and
expenses) of defending against or investigating any claim or liability in
connection with the exercise or performance of any of the powers or duties of
such Fiduciary Indemnified Person hereunder. The obligation to indemnify as set
forth in this Section 10.4(b) shall survive the resignation or removal of the
Property Trustee or the Delaware Trustee and the satisfaction and discharge of
this Declaration.

                    (c) The Sponsor agrees to pay the Property Trustee and the
Delaware Trustee, from time to time, such compensation for all services rendered
by the Property Trustee and the Dela ware Trustee hereunder as may be mutually
agreed upon in writing by the Sponsor and the Property Trustee or the Delaware
Trustee, as the case may be, and, except as otherwise expressly provided herein,
to reimburse the Property Trustee and the Delaware Trustee upon its or their
request for all reasonable expenses (including legal fees and expenses),
disbursements and advances incurred or

                                       57

<PAGE>   64


made by the Property Trustee or the Delaware Trustee, as the case may be, in
accordance with the provisions of this Declaration, except any such expense,
disbursement or advance as may be attributable to its or their negligence or bad
faith.

SECTION 10.5        OUTSIDE BUSINESSES.

                    Any Covered Person, the Sponsor, the Delaware Trustee and
the Property Trustee (subject to Section 5.3(c)) may engage in or possess an
interest in other business ventures of any nature or description, independently
or with others, similar or dissimilar to the business of the Trust, and the
Trust and the Holders shall have no rights by virtue of this Declaration in and
to such independent ventures or the income or profits derived therefrom, and the
pursuit of any such venture, even if competitive with the business of the Trust,
shall not be deemed wrongful or improper. No Covered Person, the Sponsor, the
Delaware Trustee, or the Property Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust, could be taken by the Trust,
and any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee shall have the right to take for its own account (individually or as a
partner or fiduciary) or to recommend to others any such particular investment
or other opportunity. Any Covered Person, the Delaware Trustee and the Property
Trustee may engage or be interested in any financial or other transaction with
the Sponsor or any Affiliate of the Sponsor, or may act as depositary for,
trustee or agent for, or act on any committee or body of holders of, securities
or other obligations of the Sponsor or its Affiliates.

SECTION 11.1        FISCAL YEAR.

                    The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2        CERTAIN ACCOUNTING MATTERS.

                    (a) At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Administrative Trustees.

                    (b) The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders any annual United States federal
income tax information statement required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations. Notwithstanding any right under the Code
to

                                       58

<PAGE>   65

deliver any such statement at a later date, the Administrative Trustees shall
endeavor to deliver all such information statements within 30 days after the end
of each Fiscal Year of the Trust.

                    (c) The Administrative Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Administrative Trustees on behalf of the Trust with
any state or local taxing authority.

SECTION 11.3        BANKING.

                    The Trust may maintain one or more bank accounts in the name
and for the sole benefit of the Trust; PROVIDED, HOWEVER, that all payments of
funds in respect of the Debentures held by the Property Trustee shall be made
directly to the Property Trustee Account and no other funds of the Trust shall
be deposited in the Property Trustee Account. The sole signatories for such
accounts shall be designated by the Administrative Trustees; PROVIDED, HOWEVER,
that the Property Trustee shall designate the signatories for the Property
Trustee Account.

SECTION 11.4        WITHHOLDING.

                    The Trust and the Administrative Trustees shall comply with
all withholding requirements under United States federal, state and local law.
The Trust shall request, and the Holders shall provide to the Trust, such forms
or certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably be
requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Administrative Trustees shall cause
to be filed required forms with applicable jurisdictions and, unless an
exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions. To the
extent that the Trust is required to withhold and pay over any amounts to any
authority with respect to Distributions or allocations to any Holder, the amount
withheld shall be deemed to be a Distribution in the amount of the withholding
to the Holder. In the event of any claim of excess withholding, Holders shall be
limited to an action against the applicable jurisdiction. If the amount required
to be withheld was not withheld from actual Distributions made, the Trust may
reduce subsequent Distributions by the amount of such withholding.

                            Declaration (including the terms of the Securities)
                            and that all conditions precedent to the execution
                            and delivery of such amendment have been satisfied;

PROVIDED, HOWEVER, that the Property Trustee shall not be required to sign any
such amendment; and

                        (iii) to the extent the result of such amendment
                     would be to:

                            (A) cause the Trust to fail to continue to be
                            classified for purposes of United States federal
                            income taxation as a grantor trust;

                            (B) reduce or otherwise adversely affect the powers
                            of the Property Trustee in contravention of the
                            Trust Indenture Act; or

                            (C) cause the Trust to be deemed to be an Investment
                            Company required to be registered under the

<PAGE>   67

                    (d) Section 10.1(c) and this Section 12.1 shall not be

                        (i) cure any ambiguity, correct or supplement any
                    provision in this Declaration that may be inconsistent with

                    of the Declaration to such extent as shall be necessary to
                    ensure that the Trust will be classified for United States
                    federal income tax purposes as a grantor trust at all
                    times that any Securities are outstanding or to ensure

                    Offer in the manner contemplated by the Registration

PROVIDED, HOWEVER, that in each such clause above, such action shall not
adversely affect in any material respect the interests of the Holders, and any
such amendments of this Declaration shall become effective when notice thereof
is given to the Holders.

SECTION 12.2        MEETINGS OF THE HOLDERS; ACTION BY WRITTEN CONSENT.

                    (a) Meetings of the Holders of any class of Securities may
be called at any time by the Administrative Trustees (or as provided in the
terms of the Securities) to consider and act on any matter on which Holders of
such class of Securities are entitled to act under the terms of this
Declaration, the terms of the Securities or the rules of any stock exchange on
which the Capital Securities are listed or admitted for trading. The
Administrative Trustees shall call a meeting of the Holders of such class if
directed to do so by the Holders of at least 20% in Liquidation Amount of such
class of Securities. Such direction shall be given by delivering to the
Administrative Trustees one or more notices in writing stating that the signing
Holders wish to call a meeting and indicating the general or specific purpose
for which the meeting is to be called. Any Holders calling a meeting shall
specify in writing the Capital Security Certificates held by the Holders
exercising the right to

                                       61

<PAGE>   68

call a meeting and only those Securities specified shall be counted for purposes
of determining whether the required percentage set forth in the second sentence
of this paragraph has been met.

                    (b) Except to the extent otherwise provided in the terms of
the Securities, the following provisions shall apply to meetings of Holders:

                        (i) notice of any such meeting shall be given to all
                    the Holders having a right to vote thereat at least seven
                    days and not more than 60 days before the date of such
                    meeting. Whenever a vote, consent or approval of the
                    Holders is permitted or required under this Declaration or
                    the rules of any stock exchange on which the Capital
                    Securities are listed or admitted for trading, such vote,
                    consent or approval may be given at a meeting of the
                    Holders; any action that may be taken at a meeting of the
                    Holders may be taken without a meeting if a consent in
                    writing setting forth the action so taken is signed by the
                    Holders owning not less than the minimum amount of
                    Securities in liquidation amount that would be necessary to
                    authorize or take such action at a meeting at which all
                    Holders having a right to vote thereon were present and
                    voting; prompt notice of the taking of action without a
                    meeting shall be given to the Holders entitled to vote who
                    have not consented in writing; and the Administrative
                    Trustees may specify that any written ballot submitted to
                    the Security Holder for the purpose of taking any action

                        (iii) each meeting of the Holders shall be conducted

                                     ANNEX I

                                    TERMS OF
                  9.875% CAPITAL SECURITIES, SERIES A/SERIES B
                            9.875% COMMON SECURITIES


                  Pursuant to Section 7.1 of the Amended and Restated
Declaration, dated as of October 18, 1999 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Securities are set out below (each
capitalized term used but not defined herein has the meaning set forth in the
Declaration or, if not defined in such Declaration, as defined in the Offering
Memorandum referred to below in Section 2(c) of this Annex I):

         1.  DESIGNATION AND NUMBER.

         (a) CAPITAL SECURITIES. 20,000 Series A Capital Securities of the Trust
and 20,000 Series B Capital Securities of the Trust, each series with an
aggregate liquidation amount with respect to the assets of the Trust of Twenty
Million Dollars ($20,000,000) and with a liquidation amount with respect to the
assets of the Trust of One Thousand Dollars ($1,000) (the "Liquidation Amount")
per security, are hereby designated for the purposes of identification only as "
9.875% Capital Securities, Series A" and " 9.875% Capital Securities, Series B,"
respectively (collectively, the "Capital Securities"). The certificates
evidencing the Capital Securities shall be substantially in the form of Exhibit
A-1 to the Declaration, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice or to conform
to the rules of any exchange or quotation system on or in which the Capital
Securities are listed, traded or quoted.

         (b) COMMON SECURITIES. 619 Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of Six
Hundred Nineteen Thousand Dollars ($619,000) and a liquidation amount with
respect to the assets of the Trust of $1,000 per security, are hereby designated
for the purposes of identification only as " 9.875% Common Securities" (the
"Common Securities"). The certificates evidencing the Common Securities shall be
substantially in the form of Exhibit A-2 to the Declaration, with such changes
and additions thereto or deletions therefrom as may be required by ordinary
usage, custom or practice.

         2.  DISTRIBUTIONS.

         (a) Distributions on each Security will be payable at a fixed rate per
annum of 9.875% (the "Coupon Rate") of the liquidation amount of $1000 per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee. Distributions in arrears for more than one
semi-annual period will bear additional Distributions thereon compounded semi-
annually at the Coupon Rate (to the extent permitted by applicable law).
Pursuant to the Registration Rights Agreement and the Liquidated Damages
Agreement, in certain limited circumstances the Debenture Issuer will be
required to pay Liquidated Damages (as defined in the Registration Rights
Agreement) with respect to the Debentures. The term "Distributions" as used
herein, includes distributions of any and all such interest and Liquidated
Damages, if any, payable unless otherwise

                                       I-1

<PAGE>   75

stated. A Distribution is payable only to the extent that payments are made with
respect to the Debentures held by the Property Trustee and to the extent the
Property Trustee has funds legally available therefor.

         (b) Distributions on the Securities will be cumulative, will accumulate
from the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from October 18, 1999 and will be payable
semi-annually in arrears on April 15 and October 15 of each year, commencing
April 15, 2000 (each, a "Distribution Date"), except as otherwise described
below. Distributions will be computed on the basis a 360-day year of twelve
30-day months. As long as no Event of Default has occurred and is continuing
under the Indenture, the Debenture Issuer has the right under the Indenture to
defer payments of interest by extending the interest payment period at any time
and from time to time on the Debentures for a period not exceeding 10
consecutive semi-annual periods, including the first such semi-annual period
during such period (each an "Extension Period"), during which Extension Period
no interest shall be due and payable on the Debentures, PROVIDED THAT no
Extension Period shall end on a date other than an Interest Payment Date for the
Debentures or extend beyond the Maturity Date of the Debentures. As a
consequence of such deferral, Distributions (other than Liquidated Damages, if
any) will also be deferred. Notwithstanding such deferral, Distributions will
continue to accumulate with additional Distributions thereon (to the extent
permitted by applicable law but not at a rate greater than the rate at which
interest is then accruing on the Debentures) at the Coupon Rate compounded
semi-annually during any such Extension Period. Prior to the termination of any
such Extension Period, the Debenture Issuer may further defer payments of
interest by further extending such Extension Period, PROVIDED THAT such
extension does not cause such Extension Period, together with all such previous
and further extensions within such Extension Period, to exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, end on a date other than an Interest Payment Date for the
Debentures or extend beyond the Maturity Date of the Debentures. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Debenture Issuer may commence a new Extension Period, subject to the above
requirements.

         (c) Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the close of
business on the first day of the month in which relevant the Distribution Date
occurs, which Distribution Dates correspond to the Interest Payment Dates for
the Debentures. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment with respect to the Capital
Securities will be made as described under the heading "Description of Capital
Securities--Form, Denomination, Book-Entry Procedures and Transfer" in the
Offering Memorandum dated October 13, 1999 of the Debenture Issuer and the Trust
relating to the Securities and the Debentures. The relevant record dates for the
Common Securities shall be the same as the record dates for the Capital
Securities. Distributions payable on any Securities that are not punctually paid
on any Distribution Date, as a result of the Debenture Issuer having failed to
make a payment under the Debentures, will cease to be payable to the Holder on
the relevant record date, and such defaulted Distribution will instead be
payable to the Person in whose name such Securities are registered on the
special record date or other specified date deter mined in accordance with the
Indenture. If any date on which Distributions are payable on the Securities is
not a Business Day, then payment of the Distributions payable on such date will
be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay), except that if such
next succeeding Business Day falls in the next

                                       I-2

<PAGE>   76

succeeding calendar year, such payment shall be made on the immediately
preceding Business Day with the same force and effect as if made on such date.

         (d) In the event that there is any money or other property held by or
for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders.

         3.  LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

             In the event of any dissolution of the Trust, the Trust shall
be liquidated by the Administrative Trustees as expeditiously as the
Administrative Trustees determine to be possible by distributing to the Holders,
after satisfaction of liabilities to creditors of the Trust as provided by
applicable law, a Like Amount (as defined below) of the Debentures, unless such
distribution is determined by the Property Trustee not to be practicable, in
which event such Holders will be entitled to receive out of the assets of the
Trust legally available for distribution to Holders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to the aggregate of the liquidation amount of $1,000 per Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution").

             "Like Amount" means (i) with respect to a redemption of the
Securities, Securities having a Liquidation Amount equal to the principal amount
of Debentures to be paid in accordance with their terms and (ii) with respect to
a distribution of Debentures upon the liquidation of the Trust, Debentures
having a principal amount equal to the Liquidation Amount of the Securities of
the Holder to whom such Debentures are distributed.

             If, upon any such liquidation, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets legally
available to pay in full the aggregate Liquidation Distribution, then the
amounts payable directly by the Trust with respect to the Securities shall be
paid on a Pro Rata basis.

         4.  REDEMPTION AND DISTRIBUTION.

         (a) Upon the repayment of the Debentures (with premium, if any) in
whole or in part, at maturity or otherwise (either at the option of the
Debenture Issuer or pursuant to a Special Event, as described below), the
proceeds from such repayment shall be simultaneously applied by the Property
Trustee (subject to the Property Trustee having received written notice no later
than 45 days prior to such repayment) to redeem a Like Amount of the Securities
at a redemption price equal to (i) in the case of the repayment of the
Debentures on the Maturity Date, the Maturity Redemption Price (as defined
below), (ii) in the case of the optional prepayment of the Debentures prior to
the Initial Optional Redemption Date and upon the occurrence and continuation of
a Special Event, the Special Event Redemption Price (as defined below) and (iii)
in the case of the optional prepayment of the Debentures on or after the Initial
Optional Redemption Date, the Optional Redemption Price (as defined below). The
Maturity Redemption Price, the Special Event Redemption Price and the Optional
Redemption Price are referred to collectively as the "Redemption Price". Holders
will be given not less than 30 nor more than 60 days prior written notice of
such redemption.


                                       I-3

<PAGE>   77

         (b) (i) The "Maturity Redemption Price" shall mean an amount equal to
100% of the principal of, plus accrued and unpaid interest (including Compounded
Interest and Additional Sums, if any, thereon to the date of redemption) on, the
Debentures as of the Maturity Date thereof.

                 (ii)  The Debenture Issuer shall have the right (subject to the
conditions in the Indenture) to elect to redeem the Debentures, in whole or in
part, at any time on or after October 15, 2009 (the "Initial Optional Redemption
Date"), and, simultaneous with such redemption, to cause a Like Amount of the
Securities to be redeemed by the Trust at the Optional Redemption Price on a Pro
Rata basis. "Optional Redemption Price" shall mean an amount equal to the
applicable redemption price set forth below plus, accumulated and unpaid
Distributions thereon, if any, to the date of such redemption if redeemed during
the 12-month period beginning October 15, of the years indicated below:


                                            Percentage of
               Year                      Liquidation Amount
       --------------------------   ------------------------------
           2009                               104.938%
           2010                               104.444%
           2011                               103.950%
           2012                               103.457%

           2014                               102.469%
           2015                               101.975%
           2016                               101.481%

           2018                               100.494%
           2019 and thereafter                100.000%

         (c) If at any time an Investment Company Event, a Regulatory Capital
Event or a Tax Event (each as defined below, and each a "Special Event") occurs,
the Debenture Issuer shall have the right (subject to the conditions set forth
in the Indenture) at any time prior to the Initial Optional Redemption Date, to
redeem the Debentures in whole, but not in part, within the 90 days following
the occurrence of such Special Event (the "90 Day Period"), and, simultaneous
with such redemption, to cause a Like Amount of the Securities to be redeemed by
the Trust at the Redemption Price on a Pro Rata basis.

             "Investment Company Event" shall mean the receipt by the
Debenture Issuer and the Trust of an opinion of independent securities counsel
experienced in such matters to the effect that

                                       I-4

<PAGE>   78

as a result of (a) any amendment to, or change (including any announced
prospective change) in, the laws or any regulations thereunder of the United
States or any rules, guidelines or policies of any applicable regulatory
authority for the Debenture Issuer or (b) any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or which pronouncement or
decision is announced on or after the date of original issuance of the
Securities, the Trust is, or within 90 days of the date of such opinion will be,
considered an Investment Company that is required to be registered under the
Investment Company Act.

             "Regulatory Capital Event" shall mean the receipt by the
Debenture Issuer and the Trust of an opinion of independent bank regulatory
counsel experienced in such matters to the effect that as a result of (a) any
amendment to, or change (including any announced prospective change) in, the
laws or any regulations thereunder of the United States or any rules, guidelines
or policies of an applicable regulatory authority for the Debenture Issuer or
(b) any official administrative pronouncement or judicial decision interpreting
or applying such laws or regulations, which amendment or change is effective or
which pronouncement or decision is announced on or after the date of original
issuance of the Securities, the Capital Securities do not constitute, or within
90 days of the date of such opinion will not constitute, Tier 1 Capital (or its
then equivalent if the Sponsor were subject to such capital requirement);
PROVIDED, HOWEVER, that the distribution of the Debentures in connection with
the liquidation of the Trust by the Debenture Issuer shall not in and of itself
constitute a Regulatory Capital Event.

             "Special Event Prepayment Price" shall mean, with respect to
any redemption of the Securities following a Special Event, an amount in cash
equal to the greater of (i) 100% of the principal amount of the Securities to be
prepaid or (ii) the sum, as determined by a Quotation Agent, of the present
values of the remaining scheduled payments of principal and interest on such
Securities, discounted to the prepayment date on a sem-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
plus, in the case of (i) or (ii), any accrued and unpaid interest thereon
(including Compounded Interest and Additional Sums, if any) to the date of such
prepayment.

             A "Tax Event" shall occur upon receipt by the Debenture Issuer
and the Trust of an opinion of independent tax counsel experienced in such
matters to the effect that, as a result of (a) any amendment to, or change
(including any announced prospective change) in, the laws or any regulations
thereunder of the United States or any political subdivision or taxing authority
thereof or therein, or (b) any official administrative pronouncement or judicial
decision interpreting or applying such laws or regulations, which amendment or
change is effective or which pronouncement or decision is announced on or after
the date of original issuance of the Securities, there is more than an
insubstantial risk that (i) the Trust is, or will be within 90 days of the date
of such opinion, subject to United States federal income tax with respect to
income received or accrued on the Debentures, (ii) the interest payable by the
Debenture Issuer on the Debentures is not, or within 90 days of the date of such
opinion will not be, deductible by the Debenture Issuer, in whole or in part,
for United States federal income tax purposes, or (iii) the Trust is, or will be
within 90 days of the date of such opinion, subject to more than a de minimis
amount of other taxes, duties or other governmental charges.


                                       I-5

<PAGE>   79

         (d) In the case of an optional redemption, if fewer than all the
outstanding Securities are to be so redeemed, the Common Securities and the
Capital Securities shall be redeemed Pro Rata and the Capital Securities to be
redeemed will be determined as described in Section 4(f)(ii) below. Upon the
entry of an order for the dissolution of the Trust by a court of competent
jurisdiction, the Debentures thereafter will be subject to optional redemption,
in whole, but not in part, on or after the Initial Optional Redemption Date.

         (e) On and from the date fixed by the Trustees for any distribution of
Debentures and liquidation of the Trust: (i) the Securities will no longer be
deemed to be outstanding, (ii) the Clearing Agency or its nominee (or any
successor Clearing Agency or its nominee), as the Holder of the Capital
Securities, will receive a registered global certificate or certificates
representing the Debentures to be delivered upon such distribution, and (iii)
any certificates representing Securities not held by the Clearing Agency or its
nominee (or any successor Clearing Agency or its nominee) will be deemed to
represent beneficial interests in a Like Amount of Debentures until such
certificates are presented to the Debenture Issuer or its agent for transfer or
reissue.

         (f) The Trust may not redeem fewer than all the outstanding Securities
unless all accumulated and unpaid Distributions have been paid on all Securities
for all semi-annual Distribution periods terminating on or before the date of
redemption.

         (g) The procedure with respect to redemptions or distributions of
Securities shall be as follows:

             (i) Notice of any redemption of, or notice of distribution of
         Debentures in exchange for, the Securities (a "Redemption/Distribution
         Notice") will be given by the Trust by mail to each Holder to be
         redeemed or exchanged not fewer than 30 nor more than 60 days before
         the date fixed for redemption or exchange thereof which, in the case of
         a redemption, will be the date fixed for redemption of the Debentures.
         For purposes of the calculation of the date of redemption or exchange
         and the dates on which notices are given pursuant to this Section
         4(f)(i), a Redemption/Distribution Notice shall be deemed to be given
         on the day such notice is first mailed by first-class mail, postage
         prepaid, to Holders. Each Redemption/Distribution Notice shall be
         addressed to the Holders at the address of each such Holder appearing
         in the books and records of the Trust. No defect in the
         Redemption/Distribution Notice or in the mailing of either thereof with
         respect to any Holder shall affect the validity of the redemption or
         exchange proceedings with respect to any other Holder.

             (ii) In the event that fewer than all the outstanding
         Securities are to be redeemed, the particular Securities to be redeemed
         shall be selected on a Pro Rata basis (based upon Liquidation Amounts)
         not more than 60 nor less than 30 days prior to the date fixed for
         redemption from the outstanding Securities not previously called for
         redemption; PROVIDED, HOWEVER, that with respect to Holders that would
         be required to hold less than 100 but more than zero Securities as a
         result of such redemption, the Trust shall redeem Securities of each
         such Holder so that after such redemption such Holder shall hold either
         100 Securities or such Holder no longer holds any Securities, and shall
         use such method (including, without limitation, by lot) as the Trust
         shall deem fair and appropriate; PROVIDED, FURTHER, that any

                                       I-6

<PAGE>   80

         such redemption may be made on the basis of the aggregate Liquidation
         Amount of Securities held by each Holder thereof and may be made by
         making such adjustments as the Trust deems fair and appropriate in
         order that fractional Securities shall not thereafter remain
         outstanding. With respect to Capital Securities registered in the name
         of and held of record by the Clearing Agency or its nominee (or any
         successor Clearing Agency or its nominee) or any nominee, the
         distribution of the proceeds of such redemption will be made to the
         Clearing Agency and disbursed by such Clearing Agency in accordance
         with the procedures applied by such agency or nominee.

             (iii) If Securities are to be redeemed and the Trust gives a
         Redemption/ Distribution Notice (which notice will be irrevocable),
         then (A) with respect to Capital Securities issued in book-entry form,
         by 12:00 noon, New York City time, on the redemption date, PROVIDED
         THAT the Debenture Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Debentures by 10:00 a.m., New York City time, on the Maturity Date
         or the date of redemption, as the case re quires, the Property Trustee
         will deposit irrevocably with the Clearing Agency or its nominee (or
         successor Clearing Agency or its nominee) immediately available funds
         sufficient to pay the applicable Redemption Price with respect to such
         Capital Securities and will give the Clearing Agency irrevocable
         instructions and authority to pay the Redemption Price to the relevant
         Clearing Agency Participants, and (B) with respect to Capital
         Securities issued in certificated form and Common Securities, PROVIDED
         THAT the Debenture Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Debentures, the Property Trustee will irrevocably deposit with the
         paying agent for the Capital Securities (if other than the Property
         Trustee) funds sufficient to pay the applicable Redemption Price to the
         Holders by check mailed to the address of the relevant Holder appearing
         on the books and records of the Trust on the redemption date, and
         PROVIDED FURTHER, that any such payment shall become due only upon
         surrender by the Holder of the related certificated Capital Securities.
         If a Redemption/ Distribution Notice shall have been given and funds
         deposited as required, if applicable, then immediately prior to the
         close of business on the date of such deposit, or on the redemption
         date, as applicable, Distributions will cease to accumulate on the
         Securities so called for redemption and all rights of Holders so called
         for redemption will cease, except the right of the Holders of such
         Securities to receive the Redemption Price, but without interest on
         such Redemption Price, and such Securities shall cease to be
         outstanding.

             (iv) Payment of accumulated and unpaid Distributions on the
         Redemption Date of the Securities will be subject to the rights of
         Holders at the close of business on a regular record date in respect of
         a Distribution Date occurring on or prior to such Redemption Date.

             Neither the Administrative Trustees nor the Trust shall be
required to register or cause to be registered the transfer of (i) any
Securities beginning at the opening of business 15 days before the day of
mailing of a notice of redemption or any notice of selection of Securities for
redemption or (ii) any Securities selected for redemption, except the unredeemed
portion of any Security being redeemed. If any date fixed for redemption of
Securities is not a Business Day, then payment of the Redemption Price payable
on such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay). If payment
of the Re-

                                      I-7
<PAGE>   81

demption Price with respect to any Securities is improperly withheld or refused
and not paid either by the Property Trustee or by the Sponsor as guarantor
pursuant to the relevant Securities Guarantee, Distributions on such Securities
will continue to accumulate from the original redemption date to the actual date
of payment, in which case the actual payment date will be considered the date
fixed for redemption for purposes of calculating the Redemption Price.

             (v) Redemption/Distribution Notices shall be sent by the
         Property Trustee on behalf of the Trust to (A) with respect to Capital
         Securities issued in book-entry form, the Clearing Agency or its
         nominee (or any successor Clearing Agency or its nominee), (B) with
         respect to Capital Securities issued in certificated form, to the
         Holders thereof, and (C) with respect to the Common Securities, to the
         Holders thereof.

             (vi) Subject to the foregoing and applicable law (including,
         without limitation, United States federal securities laws and banking
         laws), the Sponsor or any of its subsidiaries may at any time and from
         time to time purchase outstanding Capital Securities by tender, in the
         open market or by private agreement.

         5.  VOTING RIGHTS - CAPITAL SECURITIES.

         (a) Except as provided under Sections 5(b), 6(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights.

         (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee or executing any
trust or power conferred on such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv) consent
to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in Liquidation Amount
of all outstanding Capital Securities; PROVIDED, HOWEVER, that where a consent
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Capital Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of the Capital Securities except by subsequent vote of such Holders. The
Property Trustee shall notify each Holder of Capital Securities of any notice of
default with respect to the Debentures. In addition to obtaining the foregoing
approvals of such Holders of the Capital Securities, prior to taking any of the
foregoing actions, the Trustees shall obtain an opinion of counsel experienced
in such matters to the effect that the Trust will continue to be classified as a
grantor trust for United States federal income tax purposes after taking any
such action into account.

             If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (or, in the case of redemption, on the redemption date), then a
Holder of Capital Securities may institute a proceeding directly against the
Debenture Issuer for enforcement of payment to such Holder of the principal of
or interest on a Like Amount of

                                       I-8

<PAGE>   82

Debentures (a "Direct Action") on or after the respective due date specified in
the Debentures. In connection with such Direct Action, the Common Securities
Holder will be subrogated to the rights of such Holder of Capital Securities to
the extent of any payment made by the Debenture Issuer to such Holder of Capital
Securities in such Direct Action. Except as provided in the second preceding
sentence, or except as set forth in the first sentence of Section 3.8(e) of the
Declaration, the Holders of Capital Securities will not be able to exercise
directly any other remedy available to the holders of the Debentures.

             Any approval or direction of Holders of Capital Securities may
be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Property Trustee will cause a notice of any
meeting at which Holders of Capital Securities are entitled to vote to be mailed
to each Holder of record of Capital Securities. Each such notice will include a
statement setting forth (i) the date of such meeting or the date by which such
action is to be taken, (ii) a description of any resolution proposed for
adoption at such meeting on which such Holders are entitled to vote or of such
matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consent.

             No vote or consent of the Holders of the Capital Securities
will be required for the Trust to redeem and cancel Capital Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

             Notwithstanding that Holders of Capital Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Capital Securities that are owned by the Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

         6.  VOTING RIGHTS - COMMON SECURITIES.

         (a) Except as provided under Sections 6(b), 6(c), and 7 or as otherwise
required by law and the Declaration, the Holders of the Common Securities will
have no voting rights.

         (b) Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by the Holder of the Common
Securities. If a Debenture Event of Default has occurred and is continuing, the
Property Trustee and the Delaware Trustee may be removed at such time by the
Holders of a Majority in Liquidation Amount of the outstanding Capital
Securities. In no event will the Holders of the Capital Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in the Sponsor as the Holder of the Common
Securities. No resignation or removal of a Trustee and no appointment of a
successor trustee shall be effective until the acceptance of appointment by the
successor trustee in accordance with the provisions of the Declaration.

         (c) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture,

                                       I-9

<PAGE>   83

(iii) exercise any right to rescind or annul a declaration of acceleration of
the maturity of the principal of the Debentures or (iv) consent to any
amendment, modification or termination of the Indenture or the Debentures, where
such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of a Majority in Liquidation Amount of all outstanding
Common Securities; PROVIDED, HOWEVER, that where a consent under the Indenture
would require the consent of each holder of Debentures affected thereby, no such
consent shall be given by the Property Trustee without the prior approval of
each Holder of the Common Securities. The Trustees shall not revoke any action
previously authorized or approved by a vote of the Holders of the Common
Securities except by subsequent vote of such Holders. The Property Trustee shall
notify each Holder of Common Securities of any notice of default with respect to
the Debentures. In addition to obtaining the foregoing approvals of such Holders
of the Common Securities, prior to taking any of the foregoing actions, the
Trustees shall obtain an opinion of counsel experienced in such matters to the
effect that the Trust will continue to be classified as a grantor trust for
United States federal income tax purposes after taking any such action into
account.

             If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (or in the case of redemption, on the redemption date), then a
Holder of Common Securities may institute a Direct Action directly against the
Debenture Issuer for enforcement of payment to such Holder of the principal of
or premium, if any, or interest on a Like Amount of Debentures on or after the
respective due date specified in the Debentures. In connection with such Direct
Action, the rights of the Common Securities Holder will be subordinated to the
rights of Holders of Capital Securities in respect of any payment from the
Debenture Issuer in such Direct Action. Except as provided in the second
preceding sentence, the Holders of Common Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

             Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Administrative Trustees will cause a notice of
any meeting at which Holders of Common Securities are entitled to vote, or of
any matter upon which action by written consent of such Holders is to be taken,
to be mailed to each Holder of record of Common Securities. Each such notice
will include a statement setting forth (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought, and (iii) instructions
for the delivery of proxies or consents.

             No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

         7.  AMENDMENTS TO DECLARATION.

             In addition to the requirements set out in Section 12.1 of the
Declaration, the Declaration may be amended from time to time by the Sponsor,
the Property Trustee and the Administrative Trustees without the consent of the

other provisions with respect to matters or questions arising under the
Declaration which shall not be inconsistent with the other provisions of the
Declaration, (ii) modify, eliminate or add to any provisions of the Declaration
to such extent as shall be necessary to ensure that the Trust will be classified
for United States federal income tax purposes as a grantor trust at all times
that any Securities are outstanding or to ensure that the Trust will not be
required to register as an Investment Company under the Investment Company Act
or (iii) modify, eliminate or add any provisions of the Declaration to such
extent as shall be necessary to enable the Trust or the Sponsor to conduct an
Exchange Offer in the manner contemplated by the Registration Rights Agreement;

The Declaration may also be amended by the Trustees and the Sponsor with (i) the
consent of Holders representing a Majority in Liquidation Amount of all
outstanding Securities, and (ii) receipt by the Trustees of an Opinion of
Counsel to the effect that such amendment or the exercise of any power granted
to the Trustees in accordance with such amendment will not affect the Trust's
status as a grantor trust for United States federal income tax purposes or the
Trust's exemption from status as an Investment Company under the Investment
Company Act; PROVIDED, HOWEVER, that, without the consent of each Holder of
Trust Securities, the Declaration may not be amended to (i) change the amount or
timing of any Distribution on, or the payment required to be made in respect of,
the Trust Securities as of a specified date or (ii) restrict the right of a
Holder of Trust Securities to institute suit for the enforcement of any such
payment on or after such date.

         8.  PRO RATA.

             A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean PRO RATA to each Holder
according to the aggregate liquidation amount of the Securities held by such
Holder in relation to the aggregate liquidation amount of all Securities
outstanding unless, in relation to a payment, an Event of Default under the
Declaration has occurred and is continuing, in which case any funds available to
make such payment shall be paid first to each Holder of the Capital Securities
PRO RATA according to the aggregate liquidation amount of Capital Securities
held by such Holder relative to the aggregate liquidation amount of all Capital
Securities outstanding and then, only after satisfaction of all amounts owed to
the Holders of the Capital Securities, to each Holder of Common Securities pro
rata according to the aggregate liquidation amount of Common Securities held by
such Holder relative to the aggregate liquidation amount of all Common
Securities outstanding.

         9.  RANKING.

             The Capital Securities rank PARI PASSU with the Common

Securities, except that, if an Event of Default under the Declaration occurs and
is continuing, no payments in respect of Distributions on, or payments upon
liquidation, redemption or otherwise with respect to, the Common Securities
shall be made until the Holders of the Capital Securities shall be paid in full
the Distributions, Redemption Price, Liquidation Distribution and any other
payments to which they are entitled at such time.

         10. ACCEPTANCE OF CAPITAL SECURITIES GUARANTEE, COMMON SECURITIES
             GUARANTEE.

the acceptance thereof, agrees to the provisions of the Capital Securities
Guarantee, the Common Securities Guarantee, the Indenture and the Debentures, as
applicable, including the subordination provisions therein.

         11. NO PREEMPTIVE RIGHTS.

             Neither the issuance of Capital Securities, nor the issuance
of Common Securities is subject to preemptive or other similar rights. The
Holders shall have no preemptive or similar rights to subscribe for any
additional securities.

         12. MISCELLANEOUS.

             These terms constitute a part of the Declaration.

             The Sponsor will provide a copy of the Declaration, the
Capital Securities Guarantee or the Common Securities Guarantee, as applicable,
and the Indenture (including any supplemental indenture) to a Holder without
charge upon written request to the Trust at its principal place of business.

                          [FORM OF REVERSE OF SECURITY]


                  Distributions on each Capital Security will be payable at a
fixed rate per annum of 9.875% (the "Coupon Rate") of the liquidation amount of
$1000 per Capital Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one semi-annual period will bear interest thereon compounded semi-annually
at the Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement and the Liquidated Damages Agreement, in certain
limited circumstances the Debenture Issuer will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement) with respect to the
Debentures. The term "Distributions," as used herein, includes such cash
distributions and any and all such interest and Liquidated Damages, if any,
payable unless otherwise stated. A Distribution is payable only to the extent
that payments are made in respect of the Debentures held by the Property Trustee
and to the extent the Property Trustee has funds legally available therefor.

                  Distributions on the Capital Securities will be cumulative,
will accumulate from the most recent date to which Distributions have been paid
or, if no Distributions have been paid, from October 18, 1999 and will be
payable semi-annually in arrears, on April 15 and October 15 of each year,
commencing April 15, 2000, except as otherwise described below. Distributions
will be computed on the basis of a 360-day year of twelve 30-day months. As long
as no Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period at any time and from time to time on
the Debentures for a period not exceeding 10 consecutive semi-annual calendar
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), PROVIDED THAT no Extension Period shall end
on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures. As a consequence of such deferral,
Distributions (other than Liquidated Damages, if any) will also be deferred.
Notwithstanding such deferral, semi-annual Distributions will continue to
accumulate with interest thereon (to the extent permitted by applicable law, but
not at a rate exceeding the rate of interest then accruing on the Debentures) at
the Coupon Rate compounded semi-annually during any such Extension Period. Prior
to the termination of any Extension Period, the Debenture Issuer may further
defer payments of interest by further extending such Extension Period; PROVIDED
THAT such Extension Period, together with all such previous and further
extensions within such Extension Period, may not (i) exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, (ii) end on a date other than an Interest Payment Date for the
Debentures or (iii) extend beyond the Maturity Date of the Debentures. Payments
of accumulated Distributions will be payable to Holders as they appear on the
books and records of the Trust on the record date immediately preceding the end
of the Extension Period. Upon the termination of any Extension Period and the
payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

                  Subject to receipt by the Sponsor of any and all required
regulatory approvals and to certain other conditions set forth in the
Declaration and the Indenture, the Property Trustee may, at the direction of the
Sponsor, at any time dissolve the Trust and after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, cause the Debentures to be
distributed to the

                          [FORM OF REVERSE OF SECURITY]

         Distributions on each Common Security will be payable at a rate of
9.875% per annum (the "Coupon Rate") of the liquidation amount of $1000 per
Common Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. Distributions in arrears for more than one
semi-annual period will bear interest thereon compounded semi-annually at the
Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement, in certain limited circumstances the Debenture
Issuer will be required to pay Liquidated Damages (as defined in the
Registration Rights Agreement) with respect to the Debentures. The term
"Distributions", as used herein, includes such cash distributions and any and
all such interest and Liquidated Damages, if any, payable unless otherwise
stated. A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Property Trustee and to the extent the
Property Trustee has funds legally available therefor.

         Distributions on the Common Securities will be cumulative, will accrue
from the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from October 18, 1999 and will be payable
semi-annually in arrears, on April 15 and October 15 of each year, commencing
April 15, 2000, except as otherwise described below. Distributions will be
computed on the basis of a 360-day year of twelve 30-day months. As long as no
Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period at any time and from time to time on
the Debentures for a period not exceeding 10 consecutive calendar semi-annual
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), PROVIDED THAT no Extension Period shall end
on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures. As a consequence of such deferral,
Distributions will also be deferred. Notwithstanding such deferral, semi-annual
Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest
then accruing on the Debentures) at the Coupon Rate compounded semi-annually
during any such Extension Period. Prior to the termination of any Extension
Period, the Debenture Issuer may further defer payments of interest by further
extending such Extension Period; PROVIDED THAT such Extension Period, together
with all such previous and further extensions within such Extension Period, may
not (i) exceed 10 consecutive semi-annual periods, including the first
semi-annual period during such Extension Period, (ii) end on a date other than
an Interest Payment Date for the Debentures or (iii) extend beyond the Maturity
Date of the Debentures. Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the record date
immediately preceding the end of the Extension Period. Upon the termination of
any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.

         Subject to the receipt by the Sponsor of any and all required
regulatory approvals and to certain other conditions set forth in the
Declaration and the Indenture, the Property Trustee may, at the direction of the
Sponsor, at any time dissolve the Trust and cause the Debentures to be
distributed to the Holders of the Securities in liquidation of the Trust or,
simultaneously with any redemption of the Debentures, cause a Like Amount of the
Securities to be redeemed by the Trust.

         The Common Securities shall be redeemable as provided in the
Declaration.

         Under certain circumstances, the rights of the holders of the Common
Securities shall be subordinate to the rights of the holders of the Capital
Securities, as provided in the Declaration.

                  Distributions on each Capital Security will be payable at a
fixed rate per annum of 9.875% (the "Coupon Rate") of the liquidation amount of
$1000 per Capital Security, such rate being the rate of interest payable on the

"Distributions," as used herein, includes such cash distributions and any and
all such interest, if any, payable unless otherwise stated. A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Property Trustee and to the extent the Property Trustee has funds

                  Distributions on the Capital Securities will be cumulative,

Notwithstanding such deferral, semi-annual Distributions will continue to
accumulate with interest thereon (to the extent permitted by applicable law, but
not at a rate exceeding the rate of interest then accruing on the Debentures) at
the Coupon Rate compounded semi-annually during any such Extension Period. Prior
to the termination of any Extension Period, the Debenture Issuer may further
defer payments of interest by further extending such Extension Period; provided
that such Extension Period, together with all such previous and further
extensions within such Extension Period, may not (i) exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, (ii) end on a date other than an Interest Payment Date for the
Debentures or (iii) extend beyond the Maturity Date of the Debentures. Payments
of accumulated Distributions will be payable to Holders as they appear on the
books and records of the Trust on the record date immediately preceding the end
of the Extension Period. Upon the termination of any Extension Period and the
payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

Series A Capital Securities Guarantee, but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.

     SECTION 2.7    NOTICE OF EVENTS OF DEFAULT

prepaid, to all Holders of the Series A Capital Securities, notices of all such
Events of Default, unless such Events of Default have been cured before the
giving of such notice; PROVIDED, HOWEVER, that, except in the case of an Event
of Default arising from the non-payment of any Guarantee Payment, the Capital
Securities Guarantee Trustee shall be protected in withholding such notice if
and so long as a Responsible Officer of the Capital Securities Guarantee Trustee
in good


                                      -6-

faith determines that the withholding of such notice is in the interests of the

Trustee shall have received written notice, or a Responsible Officer of the
Capital Securities Guarantee Trustee charged with the administration of the
Declaration shall have obtained actual knowledge, of such Event of Default.

     SECTION 2.8    CONFLICTING INTERESTS

                          POWERS, DUTIES AND RIGHTS OF
                      CAPITAL SECURITIES GUARANTEE TRUSTEE

     SECTION 3.1    POWERS AND DUTIES OF THE CAPITAL SECURITIES GUARANTEE
                    TRUSTEE

     (a)  This Series A Capital Securities Guarantee shall be held by the
Capital Securities Guarantee Trustee for the benefit of the Holders of the
Series A Capital Securities, and the Capital Securities Guarantee Trustee shall
not transfer this Series A Capital Securities Guarantee to any Person except a
Holder of the Series A Capital Securities exercising his or her rights pursuant
to Section 5.4(b) or to a Successor Capital Securities Guarantee Trustee on
acceptance by such Successor Capital Securities Guarantee Trustee of its
appointment to act as Successor Capital Securities Guarantee Trustee. The right,
title and interest of the Capital Securities Guarantee Trustee shall
automatically vest in any Successor Capital Securities Guarantee Trustee, and
such vesting and succession of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Capital Securities Guarantee Trustee.

     (b)  If an Event of Default actually known to a Responsible Officer of the
Capital Securities Guarantee Trustee has occurred and is continuing, the Capital
Securities Guarantee Trustee shall enforce this Series A Capital Securities
Guarantee for the benefit of the Holders of the Series A Capital Securities.

     (c)  The Capital Securities Guarantee Trustee, before the occurrence of
any Event of Default (of which, other than a default in respect of any Guarantee
Payment, a Responsible Officer of the Property Trustee has actual knowledge) and
after the curing of all such Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Series A Capital Securities Guarantee, and no implied covenants or obligations
shall be read into this Series A Capital Securities Guarantee against the
Capital Securities Guarantee Trustee. In case an Event of Default has occurred
(that has not been cured or waived pursuant to Section 2.6) and is actually
known to a Responsible Officer of the Capital Securities Guarantee Trustee, the
Capital Securities Guarantee Trustee shall exercise such of the rights and
powers vested in it by this Series A Capital Securities Guarantee, and use the
same degree of care and skill in its exercise thereof, as


                                      -7-
<PAGE>   12

     than a default in respect of any Guarantee Payment, a Responsible Officer
     of the Property Trustee has actual knowledge) and after the curing or
     waiving of all such Events of Default that may have occurred:

          (A) the duties and obligations of the Capital Securities Guarantee

     Securities Guarantee, and no implied covenants or obligations shall be read
     into this Series A Capital Securities Guarantee against the Capital

     to the Capital Securities Guarantee Trustee and conforming to the
     requirements of this Series A Capital Securities Guarantee; PROVIDED,
     HOWEVER, that in the case of any such certificates or opinions that by any
     provision hereof are specifically required to be furnished to the Capital
     Securities Guarantee Trustee, the Capital Securities Guarantee Trustee
     shall be under a duty to examine the same to determine whether or not on
     their face they conform to the requirements of this Series A Capital
     Securities Guarantee;

          (ii) the Capital Securities Guarantee Trustee shall not be liable for
     any errors of judgment made in good faith by a Responsible Officer of the

     negligent in ascertaining the pertinent facts upon which such judgment was
     made;

          (iii) the Capital Securities Guarantee Trustee shall not be liable

     method and place of conducting any proceeding for any remedy available to
     the Capital Securities Guarantee Trustee, or exercising any trust or power
     conferred upon the Capital Securities Guarantee Trustee under this Series A
     Capital Securities Guarantee; and

          (iv) no provision of this Series A Capital Securities Guarantee shall
     require the Capital Securities Guarantee Trustee to expend or risk its own
     funds or otherwise incur personal financial liability in the performance of
     any of its duties or in the exercise of any of its rights or powers, if the
     Capital Securities Guarantee Trustee shall have reasonable grounds for
     believing that the repayment of such funds or liability is not reasonably


                                      -8-

     assured to it under the terms of this Series A Capital Securities Guarantee

          (ix) any action taken by the Capital Securities Guarantee Trustee or
     its agents hereunder shall bind the Holders of the Series A Capital
     Securities, and the signature of the Capital Securities Guarantee Trustee
     or its agents alone shall be sufficient and effective to perform any such
     action; and no third party shall be required to inquire as to the authority
     of the Capital Securities Guarantee Trustee to so act or as to its
     compliance with any of the terms and provisions of this Series A Capital

after the date notice of the Exchange Offer is mailed to the Holders. Promptly

of such Exchange Offer to enable each Holder eligible and electing to exchange
Registrable Securities for a like principal amount of Exchange Debentures or a

Holder's business and (z) has no arrangements or understandings with any Person

<PAGE>   7


Securities Act and under state securities or blue sky laws (other than requiring
minimum transfers in blocks having an aggregate principal or liquidation amount,
as the case may be, of $100,000 and multiples of $1,000 in excess thereof).

         In connection with the Exchange Offer, the Company and the Trust shall:

         (1) mail to each Holder a copy of the Prospectus forming part of the
Exchange Offer Registration Statement, together with an appropriate letter of
transmittal and related documents;

         (2) keep the Exchange Offer open for acceptance for a period of not
less than 30 days after the date notice thereof is mailed to the Holders (or
longer if required by applicable law) (such period referred to herein as the
"EXCHANGE PERIOD");

         (3) utilize the services of the Depositary for the Exchange Offer with
respect to Capital Securities represented by a global certificate;

         (4) permit Holders to withdraw tendered Securities at any time prior to
the close of business, New York time, on the last Business Day of the Exchange
Period, by sending to the institution specified in the notice to Holders, a
telegram, telex, facsimile transmission or letter setting forth the name of such
Holder, the amount of Securities delivered for exchange and a statement that
such Holder is withdrawing his election to have such Securities exchanged;

         (5) notify each Holder that any Security not tendered by such Holder in
the Exchange Offer will remain outstanding and continue to accrue interest or
accumulate distributions, as the case may be, but will not retain any rights
under this Agreement (except in the case of the Initial Purchaser and
Participating Broker-Dealers as provided herein); and

         (6) otherwise comply in all respects with all applicable laws relating
to the Exchange Offer.

         If the Initial Purchaser determines upon advice of its outside counsel
that it is not eligible to participate in the Exchange Offer with respect to the
exchange of Securities constituting any portion of an unsold allotment in the
initial placement, as soon as practicable upon receipt by the Company and the
Trust of a written request from the Initial Purchaser, the Company and the
Trust, as applicable, shall issue and deliver to the Initial Purchaser in
exchange (the "PRIVATE EXCHANGE") for the Securities held by the Initial
Purchaser a like liquidation amount of Exchange Capital Securities of the Trust
or, in the event the Trust is liquidated and Subordinated Debentures are
distributed, a like principal amount of the Exchange Debentures of the Company,
together with the Exchange Capital Securities Guarantee, in each case that are
identical (except that such securities may bear a customary legend with respect
to restrictions on transfer pursuant to the Securities Act) to the Exchange
Securities (the "PRIVATE EXCHANGE SECURITIES") and which are issued pursuant to
the Indenture or the Declaration (which provides that the Exchange Securities
will not be subject to the transfer restrictions set forth in the Indenture or
the Declaration, as applicable (other than requiring minimum transfers in blocks
having an aggregate principal or liquidation amount, as the case may be, of
$100,000 and multiples of $1,000 in excess thereof), and that the Exchange
Securities, the Private Exchange Securities and the Securities will vote and
consent together on all matters as one


                                       6
<PAGE>   8


class and that none of the Exchange Securities, the Private Exchange Securities
or the Securities will have the right to vote or consent as a separate class on
any matter). The Private Exchange Securities shall be of the same series as the
Exchange Securities, and the Company and the Trust will seek to cause the CUSIP
Service Bureau to issue the same CUSIP numbers for the Private Exchange
Securities as for the Exchange Securities issued pursuant to the Exchange Offer.

         As soon as practicable after the close of the Exchange Offer and, if
applicable, the Private Exchange, the Company and the Trust, as the case
requires, shall:

    (i)  accept for exchange all Securities or portions thereof tendered and
not validly withdrawn pursuant to the Exchange Offer or the Private Exchange;

    (ii) deliver, or cause to be delivered, to the applicable Trustee for
cancellation all Securities or portions thereof so accepted for exchange by the
Company and the Trust; and

    (iii) issue, and cause the applicable Trustee under the Indenture or
the Declaration, as applicable, to promptly authenticate and deliver to each
Holder, new Exchange Securities or Private Exchange Securities, as applicable,
equal in principal amount to the principal amount of the Subordinated Debentures
or equal in liquidation amount to the liquidation amount of the Capital
Securities as are surrendered by such Holder, and will execute, and cause the
applicable Trustee to execute, the Exchange Capital Securities Guarantee.

         Distributions on each Exchange Capital Security and interest or
distributions on each Exchange Debenture and Private Exchange Security issued
pursuant to the Exchange Offer and in the Private Exchange will accumulate or
accrue from the last date on which a distribution or interest was paid on the
Capital Security or the Subordinated Debenture surrendered in exchange therefor
or, if no distribution or interest has been paid on such Capital Security or
Subordinated Debenture, from the Issue Date. To the extent not prohibited by any
law or applicable interpretation of the staff of the SEC, the Company and the
Trust shall use their best efforts to complete the Exchange Offer as provided
above, and shall comply with the applicable requirements of the Securities Act,
the Exchange Act and other applicable laws in connection with the Exchange
Offer. The Exchange Offer shall not be subject to any conditions other than the
conditions referred to in Section 2(b)(i) and (ii) below and those conditions
that are customary in similar exchange offers. Each Holder of Registrable
Securities who wishes to exchange such Registrable Securities for Exchange
Securities in the Exchange Offer will be required to make certain customary
representations in connection therewith, including, in the case of any Holder of
Capital Securities, representations that (i) it is not an Affiliate of the Trust
or the Company, (ii) it is not a broker-dealer tendering Registrable Securities
acquired directly from the Trust or Company, (iii) the Exchange Securities to be
received by it were acquired in the ordinary course of its business and (iv) at
the time of the Exchange Offer, it has no arrangements or understandings with
any Person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Capital Securities. The Company and the Trust
shall inform the Initial Purchaser, after consultation with the applicable
Trustees, of the names and addresses of the Holders to whom the Exchange Offer
is made, and the Initial Purchaser shall have the right to contact such Holders
in order to facilitate the tender of Registrable Securities in the Exchange
Offer.

         Upon consummation of the Exchange Offer in accordance with this Section
2(a), the provisions of this Agreement shall continue to apply, MUTATIS
MUTANDIS, solely with respect to Registrable Securities that are Private
Exchange Securities and Exchange Securities held by Participating
Broker-Dealers, and the Company and the Trust shall have no further obligation
to register the Registrable Securities (other than Private Exchange Securities)
held by any Holder pursuant to Section 2(b) of this Agreement.

         (2) SHELF REGISTRATION. In the event that (i) the Company or the Trust
reasonably determine, after conferring with counsel (which may be in-house
counsel), that the Exchange Offer Registration provided in Section 2(a) above is
not available under applicable law and regulations and currently prevailing
interpretations of the staff of the SEC, (ii) the Company shall determine in
good faith that there is a reasonable likelihood that, or a material uncertainty
exists as to whether, consummation of the Exchange Offer would result in (x) the
Trust becoming subject to federal income tax with respect to income received or
accrued on the Debentures, (y) the interest payable by the Company on the
Debentures not being deductible by the Company for United States federal income
tax purposes or (z) the Trust becoming subject to more than a DE MINIMIS amount
of other taxes, duties or governmental charges, (iii) the Exchange Offer
Registration Statement is not declared effective within 180 days of the Issue
Date or (iv) upon the request of the Initial Purchaser with respect to any
Registrable Securities held by it, if the Initial Purchaser is not permitted, in
the reasonable opinion of Thacher Proffitt & Wood, pursuant to applicable law or
applicable interpretations of the staff of the SEC, to participate in the
Exchange Offer and thereby receive securities that are freely tradeable without
restriction under the Securities Act and applicable blue sky or state securities
laws (any of the events specified in (i), (ii), (iii) or (iv) being a "SHELF
REGISTRATION EVENT," and the date of occurrence thereof, the "SHELF REGISTRATION
EVENT DATE"), then in addition to or in lieu of conducting the Exchange Offer
contemplated by Section 2(a), as the case may be, the Company and the Trust
shall, at their cost, use their best efforts to cause to be filed as promptly as
practicable after such Shelf Registration Event Date, as the case may be, and,
in any event, within 45 days after such Shelf Registration Event Date (provided
that in no event shall such filing date be required to be earlier than 75 days
after the Issue Date), a Shelf Registration Statement providing for the sale by
the Holders of all of the Registrable Securities, and shall use their best
efforts to have such Shelf Registration Statement declared effective by the SEC
as soon as practicable. No Holder of Registrable Securities shall be entitled to
include any of its Registrable Securities in any Shelf Registration pursuant to
this Agreement unless and until such Holder agrees in writing to be bound by all
of the provisions of this Agreement applicable to such Holder and furnishes to
the Company and the Trust in writing, within 15 days after receipt of a request
therefor, such information as the Company and the Trust may, after conferring
with counsel with regard to information relating to Holders that would be
required by the SEC to be included in such Shelf Registration Statement or
Prospectus included therein, reasonably request for inclusion in any Shelf
Registration Statement or Prospectus included therein. Each Holder as to which
any Shelf Registration is being effected agrees to furnish to the Company and
the Trust all information with respect to such Holder necessary to make the
information previously furnished to the Company by such Holder not materially
misleading.

         The Company and the Trust agree to use their best efforts to keep the
Shelf Registration Statement continuously effective and usable for resales for
(a) the Rule 144(k) Period in the case of a Shelf Registration Statement filed
pursuant to Section 2(b)(i), (ii) or (iii) or (b) 180


                                       8
<PAGE>   10


days in the case of a Shelf Registration Statement filed pursuant to Section
2(b)(iv) (subject in each case to extension pursuant to the last paragraph of
Section 3 hereof), or for such shorter period which will terminate when all of
the Securities covered by the Shelf Registration Statement have been sold
pursuant to the Shelf Registration Statement or cease to be Registrable
Securities (the "EFFECTIVENESS PERIOD"). The Company and the Trust shall not
permit any securities other than Registrable Securities to be included in the
Shelf Registration. The Company and the Trust will, in the event a Shelf
Registration Statement is declared effective, provide to each Holder a
reasonable number of copies of the Prospectus which is a part of the Shelf
Registration Statement, notify each such Holder when the Shelf Registration has
become effective and take certain other actions as are required to permit
certain unrestricted resales of the Registrable Securities. The Company and the
Trust further agree, if necessary, to supplement or amend the Shelf Registration
Statement, if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Shelf Registration Statement
or by the Securities Act or by any other rules and regulations thereunder for
shelf registrations, and the Company and the Trust agree to furnish to the
Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

         (3) EXPENSES. The Company, as issuer of the Subordinated Debentures,
shall pay all Registration Expenses in connection with any Registration
Statement filed pursuant to Section 2(a) and/or 2(b) hereof and will reimburse
the Initial Purchaser for the reasonable fees and disbursements of Thacher
Proffitt & Wood, counsel for the Initial Purchaser, incurred in connection with
the Exchange Offer and, if applicable, the Private Exchange, and either Thacher
Proffitt & Wood or any other single counsel designated in writing by the
Majority Holders to act as counsel for the Holders of the Registrable Securities
in connection with a Shelf Registration Statement, which other counsel shall be
reasonably satisfactory to the Company. Except as provided herein, each Holder
shall pay all expenses of its counsel, underwriting discounts and commissions
and transfer taxes, if any, relating to the sale or disposition of such Holder's
Registrable Securities pursuant to the Shelf Registration Statement.

         (4) EFFECTIVE REGISTRATION STATEMENT. An Exchange Offer Registration
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof will not be deemed to have become effective
unless it has been declared effective by the SEC; PROVIDED, HOWEVER, that if,
after it has been declared effective, the offering of Registrable Securities
pursuant to such Exchange Offer Registration Statement or Shelf Registration
Statement is interfered with by any stop order, injunction or other order or
requirement of the SEC or any other governmental agency or court, such Exchange
Offer Registration Statement or Shelf Registration Statement will be deemed not
to have been effective during the period of such interference, until the
offering of Registrable Securities pursuant to such Registration Statement may
legally resume. The Company and the Trust will be deemed not to have used their
best efforts to cause the Exchange Offer Registration Statement or the Shelf
Registration Statement, as the case may be, to become, or to remain, effective
during the requisite period if either of them voluntarily takes any action that
would result in any such Registration Statement not being declared effective or
that would result in the Holders of Registrable Securities covered thereby not
being able to exchange or offer and sell such Registrable Securities during that
period, unless such action is required by applicable law.

         (5) LIQUIDATED DAMAGES AND ADDITIONAL DISTRIBUTIONS. In the event that:

     (1)  neither the Exchange Offer Registration Statement is filed with the
SEC on or prior to the 150th day after the Issue Date nor a Shelf Registration
Statement is filed with the SEC on or prior to the 45th day after the Shelf
Registration Event Date in respect of a Shelf Registration Event attributable to
any of the events set forth in Sections 2(b)(i), (ii) and (iii) (provided that
in no event shall such filing date be required to be earlier than 75 days after
the Issue Date), then commencing on the day after the applicable required filing
date, liquidated damages ("LIQUIDATED DAMAGES") shall accrue on the principal
amount of the Subordinated Debentures, and additional distributions ("ADDITIONAL
DISTRIBUTIONS") shall accumulate on the liquidation amount of the Trust
Securities (as such term is defined in the Declaration), each at a rate of 25
basis points per annum; or

     (2)  neither the Exchange Offer Registration Statement is declared
effective by the SEC on or prior to the 180th day after the Issue Date nor a
Shelf Registration Statement is declared effective by the SEC on or prior to the
later of (A) the 40th day after the date such Shelf Registration Statement was
required to be filed and (B) the 180th day after the Issue Date, in respect of a
Shelf Registration Event attributable to any of the events set forth in Sections
2(b)(i), (ii) and (iii), then, commencing on the day after the applicable
required effectiveness date, Liquidated Damages shall accrue on the principal
amount of the Subordinated Debentures, and Additional Distributions shall
accumulate on the liquidation amount of the Trust Securities, each at a rate of
25 basis points per annum; or

     (3)  (A) the Trust has not exchanged Exchange Capital Securities for all
Capital Securities or the Company has not exchanged Exchange Debentures for all
Subordinated Debentures, in each case validly tendered during the Exchange
Period, or executed the Exchange Capital Securities Guarantee in respect of the
Exchange Capital Securities, in accordance with the terms of the Exchange Offer
on or prior to the 45th day after the date on which the Exchange Offer
Registration Statement was declared effective or (B) if applicable, the Shelf
Registration Statement in respect of a Shelf Registration Event attributable to
any of the events set forth in Sections 2(b)(i), (ii) and (iii) has been
declared effective and such Shelf Registration Statement ceases to be effective
or usable for resales (whether as a result of an event contemplated by Section
3(e) or otherwise) at any time prior to the expiration of the Rule 144(k) Period
(other than after such time as all Securities have been disposed of thereunder
or otherwise cease to be Registered Securities), then Liquidated Damages shall
accrue on the principal amount of Subordinated Debentures, and Additional
Distributions shall accumulate on the liquidation amount of the Trust
Securities, each at a rate of 25 basis points per annum commencing on (x) the
46th day after such effective date, in the case of (A) above, or (y) the day
such Shelf Registration Statement ceases to be effective or usable for resales,
in the case of (B) above;

PROVIDED, HOWEVER, that neither the Liquidated Damages rate on the Subordinated
Debentures, nor the Additional Distribution rate on the liquidation amount of
the Trust Securities, may exceed in the aggregate 25 basis points per annum;
PROVIDED, FURTHER, HOWEVER, that (1) upon the filing of the Exchange Offer
Registration Statement or a Shelf Registration Statement (in the case of clause
(i) above), (2) upon the effectiveness of the Exchange Offer Registration
Statement or a Shelf Registration Statement (in the case of clause (ii) above)
or (3) upon the exchange of Exchange Capital Securities and Exchange Debentures
for all Capital Securities and Subordinated Debentures


                                       10
<PAGE>   12


validly tendered and execution of the Exchange Capital Securities Guarantee (in
the case of clause (iii)(A) above) or at such time as the Shelf Registration
Statement that had ceased to remain effective or usable for resales again
becomes effective and usable for resales (in the case of clause (iii)(B) above),
Liquidated Damages on the principal amount of the Subordinated Debentures and
Additional Distributions on the liquidation amount of the Trust Securities as a
result of such clause (or the relevant subclause thereof) shall cease to accrue
and accumulate, as the case may be.

         Any amounts of Liquidated Damages and Additional Distributions due
pursuant to Section 2(e)(i), (ii) or (iii) above will be payable in cash on the
next succeeding March 31 and September 30, as the case may be, to Holders on the
relevant record dates for the payment of interest and distributions pursuant to
the Indenture and the Declaration, respectively.

         (6) SPECIFIC ENFORCEMENT. Without limiting the remedies available to
the Holders, the Company and the Trust acknowledge that any failure by the
Company or the Trust to comply with its obligations under Section 2(a) and
Section 2(b) hereof may result in material irreparable injury to the Holders for
which there is no adequate remedy at law, that it would not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, any Holder may obtain such relief as may be required to specifically
enforce the Company's and the Trust's obligations under Section 2(a) and Section
2(b) hereof.

         (7) DISTRIBUTION OF SUBORDINATED DEBENTURES. Notwithstanding any other
provisions of this Agreement, in the event that Subordinated Debentures are
distributed to holders of Capital Securities in liquidation of the Trust
pursuant to the Declaration, (i) all references in this Section 2 and in Section
3 to Securities, Registrable Securities and Exchange Securities shall not
include the Capital Securities and Capital Securities Guarantee or the Exchange
Capital Securities and Exchange Capital Securities Guarantee issued or to be
issued in exchange therefor in the Exchange Offer and (ii) all requirements for
any action to be taken by the Trust in this Section 2 and in Section 3 shall
cease to apply and all requirements for any action to be taken by the Company in
this Section 2 and in Section 3 shall apply to the Subordinated Debentures and
Exchange Debentures issued or to be issued in exchange therefor in the Exchange
Offer.

         3. REGISTRATION PROCEDURES. In connection with the obligations of the
Company and the Trust with respect to the Registration Statements pursuant to
Sections 2(a) and 2(b) hereof, the Company and the Trust shall use their best
efforts to:

         (1) prepare and file with the SEC a Registration Statement or
Registration Statements as prescribed by Sections 2(a) and 2(b) hereof within
the relevant time period specified in Section 2 hereof on the appropriate form
under the Securities Act, which form (i) shall be selected by the Company and
the Trust, (ii) shall, in the case of a Shelf Registration, be available for the
sale of the Registrable Securities by the selling Holders thereof and, in the
case of an Exchange Offer, be available for the exchange of Registrable
Securities and (iii) shall comply as to form in all material respects with the
requirements of the applicable form and include all financial statements
required by the SEC to be filed therewith; and use their best efforts to cause
such Registration Statement to become effective and remain effective (and, in
the case of a Shelf Registration Statement, usable for resales) in accordance
with Section 2 hereof; PROVIDED, HOWEVER, that if (1) such filing is pursuant to
Section 2(b), or (2) a Prospectus contained in an Exchange Offer


                                       11
<PAGE>   13


Registration Statement filed pursuant to Section 2(a) is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto, the Company and the Trust
shall furnish to and afford the Holders of the Registrable Securities and each
such Participating Broker-Dealer, as the case may be, covered by such
Registration Statement, their counsel and the managing underwriters, if any, a
reasonable opportunity (not to exceed seven Business Days) to review copies of
all such documents (including copies of any documents to be incorporated by
reference therein and all exhibits thereto) proposed to be filed. The Company
and the Trust shall not file any Registration Statement or Prospectus or any
amendments or supplements thereto in respect of which the Holders must be
afforded an opportunity to review prior to the filing of such document if the
Majority Holders or such Participating Broker-Dealer, as the case may be, their
counsel or the managing underwriters, if any, shall reasonably object in a
timely manner;

         (2) prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement effective for the Effectiveness Period or the Applicable
Period, as the case may be; and cause each Prospectus to be supplemented, if so
determined by the Company or the Trust or requested by the SEC, by any required
prospectus supplement and as so supplemented to be filed pursuant to Rule 424
(or any similar provision then in force) under the Securities Act, and comply
with the provisions of the Securities Act, the Exchange Act and the rules and
regulations promulgated thereunder applicable to it with respect to the
disposition of all securities covered by each Registration Statement during the
Effectiveness Period or the Applicable Period, as the case may be, in accordance
with the intended method or methods of distribution by the selling Holders
thereof described in this Agreement (including sales by any Participating
Broker-Dealer);

         (3) in the case of a Shelf Registration, (i) notify each Holder of
Registrable Securities included in the Shelf Registration Statement, at least
three Business Days prior to filing, that a Shelf Registration Statement with
respect to the Registrable Securities is being filed and advising such Holder
that the distribution of Registrable Securities will be made in accordance with
the method selected by the Majority Holders; and (ii) furnish to each Holder of
Registrable Securities included in the Shelf Registration Statement and to each
underwriter of an underwritten offering of Registrable Securities, if any,
without charge, as many copies of each Prospectus, including each preliminary
Prospectus, and any amendment or supplement thereto, and such other documents as
such Holder or underwriter may reasonably request, in order to facilitate the
public sale or other disposition of the Registrable Securities; and (iii)
consent to the use of the Prospectus or any amendment or supplement thereto by
each of the selling Holders of Registrable Securities included in the Shelf
Registration Statement in connection with the offering and sale of the
Registrable Securities covered by the Prospectus or any amendment or supplement
thereto;

         (4) in the case of a Shelf Registration, register or qualify the
Registrable Securities under all applicable state securities or "blue sky" laws
of such jurisdictions by the time the applicable Registration Statement is
declared effective by the SEC as any Holder of Registrable Securities covered by
a Registration Statement and each underwriter of an underwritten offering of
Registrable Securities shall reasonably request in writing in advance of such
date of effectiveness, and do any and all other acts and things which may be
reasonably necessary or advisable to enable such Holder and underwriter to
consummate the disposition in each such jurisdiction of such


                                       12
<PAGE>   14


Registrable Securities owned by such Holder; PROVIDED, HOWEVER, that the Company
and the Trust shall not be required to (i) qualify as a foreign corporation or
as a dealer in securities in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d), (ii) file any general consent to
service of process in any jurisdiction where it would not otherwise be subject
to such service of process or (iii) subject itself to taxation in any such
jurisdiction if it is not then so subject;

         (5) (1) in the case of a Shelf Registration or (2) if Participating
Broker-Dealers from whom the Company or the Trust has received prior written
notice that they will be utilizing the Prospectus contained in the Exchange
Offer Registration Statement as provided in Section 3(u) hereof, are seeking to
sell Exchange Securities and are required to deliver Prospectuses, promptly
notify each Holder of Registrable Securities, or such Participating
Broker-Dealers, as the case may be, their counsel and the managing underwriters,
if any, and promptly confirm such notice in writing (i) when a Registration
Statement has become effective and when any post-effective amendments thereto
become effective, (ii) of any request by the SEC or any state securities
authority for amendments and supplements to a Registration Statement or
Prospectus or for additional information after the Registration Statement has
become effective, (iii) of the issuance by the SEC or any state securities
authority of any stop order suspending the effectiveness of a Registration
Statement or the qualification of the Registrable Securities or the Exchange
Securities to be offered or sold by any Participating Broker-Dealer in any
jurisdiction described in paragraph 3(d) hereof or the initiation of any
proceedings for that purpose, (iv) in the case of a Shelf Registration, if,
between the effective date of a Registration Statement and the closing of any
sale of Registrable Securities covered thereby, the representations and
warranties of the Company and the Trust contained in any purchase agreement,
securities sales agreement or other similar agreement cease to be true and
correct in all material respects, (v) of the happening of any event or the
failure of any event to occur or the discovery of any facts, during the
Effectiveness Period, which makes any statement made in such Registration
Statement or the related Prospectus untrue in any material respect or which
causes such Registration Statement or Prospectus to omit to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and (vi) of the
reasonable determination of the Company and the Trust that a post-effective
amendment to the Registration Statement would be appropriate;

         (6) obtain the withdrawal of any order suspending the effectiveness of
a Registration Statement at the earliest possible moment;

         (7) in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities included within the coverage of such Shelf Registration
Statement, without charge, at least one conformed copy of each Registration
Statement relating to such Shelf Registration and any post-effective amendment
thereto (without documents incorporated therein by reference or exhibits
thereto, unless requested);

         (8) in the case of a Shelf Registration, cooperate with the selling
Holders of Registrable Securities to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends (other than with respect to restrictions
requiring minimum transfers in blocks having an aggregate principal or
liquidation amount, as the case may be, of $100,000 and multiples of $1,000 in
excess thereof) and in such


                                       13
<PAGE>   15


denominations (consistent with the provisions of the Indenture and the
Declaration) and registered in such names as the selling Holders or the
underwriters may reasonably request at least two Business Days prior to the
closing of any sale of Registrable Securities pursuant to such Shelf
Registration Statement;

         (9) in the case of a Shelf Registration or an Exchange Offer
Registration, promptly after the occurrence of any event specified in Section
3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, prepare a supplement or
post-effective amendment to such Registration Statement or the related
Prospectus or any document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the purchasers of the
Registrable Securities, such Prospectus will not include any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; and to notify each Holder to suspend use of the Prospectus
as promptly as practicable after the occurrence of such an event, and each
Holder hereby agrees to suspend use of the Prospectus until the Company has
amended or supplemented the Prospectus to correct such misstatement or omission;

         (10) in the case of a Shelf Registration, a reasonable time prior to
the filing of any document which is to be incorporated by reference into a
Registration Statement or a Prospectus after the initial filing of a
Registration Statement, provide a reasonable number of copies of such document
to the Holders; and make such of the representatives of the Company and the
Trust as shall be reasonably requested by the Holders of Registrable Securities
or the Initial Purchaser on behalf of such Holders available for discussion of
such document;

         (11) obtain a CUSIP number for all Exchange Capital Securities and the
Capital Securities (and, if the Trust has made a distribution of the
Subordinated Debentures to the Holders of the Capital Securities, the
Subordinated Debentures or the Exchange Debentures), as the case may be, not
later than the effective date of a Registration Statement, and provide the
applicable Trustee with certificates for the Exchange Securities or the
Registrable Securities, as the case may be, in a form eligible for deposit with
the Depositary;

         (12) cause the Indenture, the Declaration, the Capital Securities
Guarantee (in the case of a Shelf Registration) and the Exchange Capital
Securities Guarantee (in the case of an Exchange Offer Registration) to be
qualified under the TIA, in connection with the registration of the Exchange
Securities or Registrable Securities, as the case may be, and effect such
changes to such documents as may be required for them to be so qualified in
accordance with the terms of the TIA and execute, and cause the applicable
Trustee to execute, all documents as may be required to effect such changes, and
all other forms and documents required to be filed with the SEC to enable such
documents to be so qualified in a timely manner;

         (13) in the case of a Shelf Registration, enter into such agreements
(including underwriting agreements) as are customary in underwritten offerings
and take all such other appropriate actions in connection therewith as are
reasonably requested by the Holders of at least 25% in aggregate principal or
liquidation amount, as the case may be, of the Registrable Securities in order
to expedite or facilitate the registration or the disposition or the Registrable
Securities;


                                       14
<PAGE>   16


         (14) in the case of a Shelf Registration, whether or not an
underwriting agreement is entered into and whether or not the registration is an
underwritten registration, if requested by (x) the Initial Purchaser, in the
case where the Initial Purchaser holds Securities acquired by it as part of its
initial placement and (y) Holders of at least 25% in aggregate principal or
liquidation amount, as the case may be, of the Registrable Securities covered
thereby: (i) make such representations and warranties to Holders of such
Registrable Securities and the underwriters (if any), with respect to the
business of the Trust, the Company and the subsidiaries of the Company as then

confirm the same if and when requested; (ii) obtain opinions of counsel to the
Company and the Trust and updates thereof (which may be in the form of a
reliance letter) in form and substance reasonably satisfactory to the managing
underwriters (if any) and the Holders of a majority in aggregate principal or

sold, addressed to each selling Holder and the underwriters (if any) covering
the matters customarily covered in opinions requested in underwritten offerings
and such other matters as may be reasonably requested by such underwriters (it
being agreed that the matters to be covered by such opinion may be subject to
customary qualifications and exceptions); (iii) obtain "cold comfort" letters

financial statements and financial data are, or are required to be, included in
the Registration Statement), addressed to each of the underwriters, such letters
to be in customary form and covering matters of the type customarily covered in
"cold comfort" letters in connection with underwritten offerings and such other
matters as reasonably requested by such underwriters in accordance with
Statement on Auditing Standards No. 72; and (iv) if an underwriting agreement is
entered into, the same shall contain indemnification provisions and procedures
no less favorable than those set forth in Section 4 hereof (or such other
provisions and procedures acceptable to Holders of a majority in aggregate
principal or liquidation amount, as the case may be, of Registrable Securities
covered by such Registration Statement and the managing underwriters) customary
for such agreements with respect to all parties to be indemnified pursuant to
said Section (including, without limitation, such underwriters and selling
Holders); and in the case of an underwritten registration, the above
requirements shall be satisfied at each closing under the related underwriting
agreement or as and to the extent required thereunder;


         (15) if (1) a Shelf Registration is filed pursuant to Section 2(b) or
(2) a Prospectus contained in an Exchange Offer Registration Statement filed
pursuant to Section 2(a) is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Securities during the
Applicable Period, make reasonably available for inspection by any selling
Holder of Registrable Securities or Participating Broker-Dealer, as applicable,
who certifies to the Company and the Trust that it has a current intention to
sell Registrable Securities pursuant to the Shelf Registration, any underwriter
participating in any such disposition of Registrable Securities, if any, and any
attorney, accountant or other agent retained by any such selling Holder,
Participating Broker-Dealer, as the case may be, or underwriter (collectively,
the "INSPECTORS"), at the offices where normally kept, during the Company's
normal business hours, all financial and other records, pertinent corporate
documents and properties of the Trust, the Company and its subsidiaries
(collectively, the "RECORDS") as shall be reasonably necessary to enable them to
exercise any


                                       15
<PAGE>   17


applicable due diligence responsibilities, and cause the officers, directors and
employees of the Trust, the Company and its subsidiaries to supply all relevant
information in each case reasonably requested by any such Inspector in
connection with such Registration Statement; records and information which the
Company and the Trust determine, in good faith, to be confidential and any
Records and information which it notifies the Inspectors are confidential shall
not be disclosed to any Inspector except where (i) the disclosure of such
Records or information is necessary to avoid or correct a material misstatement
or omission in such Registration Statement, (ii) the release of such Records or
information is ordered pursuant to a subpoena or other order from a court of
competent jurisdiction or is necessary in connection with any action, suit or
proceeding or (iii) such Records or information previously has been made
generally available to the public; each selling Holder of such Registrable
Securities and each such Participating Broker-Dealer will be required to agree
in writing that Records and information obtained by it as a result of such
inspections shall be deemed confidential and shall not be used by it as the
basis for any market transactions in the securities of the Trust or the Company
unless and until such is made generally available to the public through no fault
of an Inspector or a selling Holder; and each selling Holder of such Registrable
Securities and each such Participating Broker-Dealer will be required to further
agree in writing that it will, upon learning that disclosure of such Records or
information is sought in a court of competent jurisdiction, or in connection
with any action, suit or proceeding, give notice to the Company and allow the
Company at its expense to undertake appropriate action to prevent disclosure of
the Records and information deemed confidential;

         (16) comply with all applicable rules and regulations of the SEC so
long as any provision of this Agreement shall be applicable and make generally
available to its securityholders earning statements satisfying the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
promulgated under the Securities Act) no later than 45 days after the end of any
12-month period (or 90 days after the end of any 12-month period if such period
is a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to underwriters in a firm commitment or best
efforts underwritten offering and (ii) if not sold to underwriters in such an
offering, commencing on the first day of the first fiscal quarter of the Company
after the effective date of a Registration Statement, which statements shall
cover said 12-month periods, provided that the obligations under this paragraph
(p) shall be satisfied by the timely filing of quarterly and annual reports on
Forms 10-Q and 10-K under the Exchange Act;

         (17) upon consummation of an Exchange Offer or a Private Exchange, if
requested by a Trustee, obtain an opinion of counsel to the Company addressed to
the Trustee for the benefit of all Holders of Registrable Securities
participating in the Exchange Offer or the Private Exchange, as the case may be,
substantially to the effect that (i) each of the Company and the Trust, as the
case requires, has duly authorized, executed and delivered the Exchange
Securities and Private Exchange Securities, and (ii) each of the Exchange
Securities or the Private Exchange Securities, as the case may be, constitutes a
validly issued, fully paid and nonassessable undivided beneficial ownership
interest in the assets of the Trust (in the case of an Exchange Capital
Security) or a legal, valid and binding obligation of the Company, enforceable
against the Company, in accordance with its respective terms (in the case of an
Exchange Debenture and the Exchange Capital Securities Guarantee), as the case
may be (in each case, with customary exceptions);



                                       16
<PAGE>   18



         (18) if an Exchange Offer or a Private Exchange is to be consummated,
upon delivery of the Registrable Securities by Holders to the Company or the
Trust, as applicable (or to such other Person as directed by the Company or the
Trust, respectively), in exchange for the Exchange Securities or the Private
Exchange Securities, as the case may be, the Company or the Trust, as
applicable, shall mark, or cause to be marked, on such Registrable Securities
delivered by such Holders that such Registrable Securities are being canceled in
exchange for the Exchange Securities or the Private Exchange Securities, as the
case may be; it being understood that in no event shall such Registrable
Securities be marked as paid or otherwise satisfied;

         (19) cooperate with each seller of Registrable Securities covered by
any Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Securities and their respective counsel in
connection with any filings required to be made with the NASD;

         (20) take all other steps necessary to effect the registration of the
Registrable Securities covered by a Registration Statement contemplated hereby;

         (21) (A) in the case of the Exchange Offer Registration Statement (i)
include in the Exchange Offer Registration Statement a section entitled "Plan of
Distribution," which section shall be reasonably acceptable to the Initial
Purchaser or another representative of the Participating Broker-Dealers, and
which shall contain a summary statement of the positions taken or policies made
by the staff of the SEC with respect to the potential "underwriter" status of
any broker-dealer that holds Registrable Securities acquired for its own account
as a result of market-making activities or other trading activities (a
"PARTICIPATING BROKER-DEALER") and that will be the beneficial owner (as defined
in Rule 13d-3 under the Exchange Act) of Exchange Securities to be received by
such broker-dealer in the Exchange Offer, whether such positions or policies
have been publicly disseminated by the staff of the SEC or such positions or
policies, in the reasonable judgment of the Initial Purchaser or such other
representative, represent the prevailing views of the staff of the SEC,
including a statement that any such broker-dealer who receives Exchange
Securities for Registrable Securities pursuant to the Exchange Offer may be
deemed a statutory underwriter and must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such
Exchange Securities, (ii) furnish to each Participating Broker-Dealer who has
delivered to the Company the notice referred to in Section 3(e), without charge,
as many copies of each Prospectus included in the Exchange Offer Registration
Statement, including any preliminary Prospectus, and any amendment or supplement
thereto, as such Participating Broker-Dealer may reasonably request (each of the
Company and the Trust hereby consents to the use of the Prospectus forming part
of the Exchange Offer Registration Statement or any amendment or supplement
thereto by any Person subject to the prospectus delivery requirements of the
Securities Act, including all Participating Broker-Dealers, in connection with
the sale or transfer of the Exchange Securities covered by the Prospectus or any
amendment or supplement thereto), (iii) use their best efforts to keep the
Exchange Offer Registration Statement effective and to amend and supplement the
Prospectus contained therein in order to permit such Prospectus to be lawfully
delivered by all Persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such Persons must comply with such
requirements under the Securities Act and applicable rules and regulations in
order to resell the Exchange Securities; PROVIDED, HOWEVER, that such period
shall not be required to exceed 90 days (or such longer period if extended
pursuant to the last sentence of Section 3 hereof) (the


                                       17
<PAGE>   19


"APPLICABLE PERIOD"), and (iv) include in the transmittal letter or similar
documentation to be executed by an exchange offeree in order to participate in
the Exchange Offer (x) the following provision:

          "If the exchange offeree is a broker-dealer holding
           Registrable Securities acquired for its own account
           as a result of market-making activities or other
           trading activities, it will deliver a prospectus
           meeting the requirements of the Securities Act in
           connection with any resale of Exchange Securities
           received in respect of such Registrable Securities
           pursuant to the Exchange Offer";

and (y) a statement to the effect that by a broker-dealer making the
acknowledgment described in clause (x) and by delivering a Prospectus in
connection with the exchange of Registrable Securities, the broker-dealer will
not be deemed to admit that it is an underwriter within the meaning of the
Securities Act; and (B) in the case of any Exchange Offer Registration
Statement, the Company and the Trust agree to deliver to the Initial Purchaser
or to another representative of the Participating Broker-Dealers, if requested
by the Initial Purchaser or such other representative of Participating
Broker-Dealers, on behalf of the Participating Broker-Dealers upon consummation
of the Exchange Offer (i) an opinion of counsel in form and substance reasonably
satisfactory to the Initial Purchaser or such other representative of the
Participating Broker-Dealers, covering the matters customarily covered in
opinions requested in connection with Exchange Offer Registration Statements and
such other matters as may be reasonably requested (it being agreed that the
matters to be covered by such opinion may be subject to customary qualifications
and exceptions), (ii) an officers' certificate containing certifications
substantially similar to those set forth in Section 5(g) of the Purchase
Agreement and such additional certifications as are customarily delivered in a
public offering of debt securities and (iii) as well as upon the effectiveness
of the Exchange Offer Registration Statement, a comfort letter, in each case, in
customary form if permitted by Statement on Auditing Standards No. 72.

         The Company or the Trust may require each seller of Registrable
Securities as to which any registration is being effected to furnish to the
Company or the Trust, as applicable, such information regarding such seller as
may be required by the staff of the SEC to be included in a Registration
Statement. The Company or the Trust may exclude from such registration the
Registrable Securities of any seller who unreasonably fails to furnish such
information within a reasonable time after receiving such request. The Company
shall have no obligation to register under the Securities Act the Registrable
Securities of a seller who so fails to furnish such information.

         In the case of a Shelf Registration Statement, or if Participating
Broker-Dealers who have notified the Company and the Trust that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in this Section 3(u) hereof, are seeking to sell Exchange Securities
and are required to deliver Prospectuses, each Holder agrees that, upon receipt
of any notice from the Company or the Trust of the occurrence of any event
specified in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, such
Holder will forthwith discontinue disposition of Registrable Securities pursuant
to a Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof or until
it is advised in writing (the "ADVICE") by the Company and the Trust that the
use of the applicable Prospectus may


                                       18
<PAGE>   20


be resumed, and, if so directed by the Company and the Trust, such Holder will
deliver to the Company or the Trust (at the Company's or the Trust's expense, as
the case requires) all copies in such Holder's possession, other than permanent
file copies then in such Holder's possession, of the Prospectus covering such
Registrable Securities or Exchange Securities, as the case may be, current at
the time of receipt of such notice. If the Company or the Trust shall give any
such notice to suspend the disposition of Registrable Securities or Exchange
Securities, as the case may be, pursuant to a Registration Statement, the
Company and the Trust shall use their best efforts to file and have declared
effective (if an amendment) as soon as practicable after the resolution of the
related matters an amendment or supplement to the Registration Statement and
shall extend the period during which such Registration Statement is required to
be maintained effective and usable for resales pursuant to this Agreement by the
number of days in the period from and including the date of the giving of such
notice to and including the date when the Company and the Trust shall have made
available to the Holders (x) copies of the supplemented or amended Prospectus
necessary to resume such dispositions or (y) the Advice.

         4. INDEMNIFICATION AND CONTRIBUTION. (a) In connection with any
Registration Statement, the Company and the Trust shall, jointly and severally,
indemnify and hold harmless the Initial Purchaser, each Holder, each underwriter
who participates in an offering of the Registrable Securities, each
Participating Broker-Dealer, each Person, if any, who controls any of such
parties within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act and each of their respective partners, directors, officers,
employees and agents as follows:

     (1) against any and all loss, liability, claim, damage and expense
whatsoever, as incurred, arising out of any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement (or any
amendment or supplement thereto), covering Registrable Securities or Exchange
Securities, as applicable, or the omission or alleged omission therefrom of 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;

     (2) against any and all loss, liability, claim, damage and expense
whatsoever, as incurred, to the extent of the aggregate amount paid in
settlement of any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or of any claim whatsoever
based upon any such untrue statement or omission, or any such alleged untrue
statement or omission in the Registration Statement; provided that (subject to
Section 4(d) hereof) any such settlement is effected with the prior written
consent of the Company and the Trust; and

     (3) against any and all expenses whatsoever, as incurred (including the
fees and disbursements of counsel, except to the extent otherwise expressly
provided in Section 4(c) hereof), reasonably incurred in investigating,
preparing or defending against any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue statement or omission, or any such
alleged untrue statement or omission, to the extent that any such expense is not
paid under subparagraph (i) or (ii) of this Section 4(a);

PROVIDED, HOWEVER, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent arising out of an untrue statement or
omission


                                       19
<PAGE>   21


or alleged untrue statement or omission made in reliance upon and in conformity
with written information furnished in writing to the Company or the Trust by the
Initial Purchaser or such Holder, underwriter or Participating Broker-Dealer for
use in a Registration Statement (or any amendment thereto) or any Prospectus (or
any amendment or supplement thereto).

     (2) The Initial Purchaser and each Holder, underwriter or Participating
Broker-Dealer agrees, severally and not jointly, to indemnify and hold harmless
the Company, its directors and officers (including each officer of the Company
and the Trust who signed the Registration Statement), the Trust, each of the
Trustees and each Person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act against any
and all loss, liability, claim, damage and expense whatsoever described in the
indemnity contained in Section 4(a) hereof, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in a Registration Statement (or any amendment thereto) or any Prospectus
(or any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company or the Trust by such Holder,
underwriter or Participating Broker-Dealer, as the case maybe, expressly for use
in such Registration Statement (or any amendment thereto), or any such
Prospectus (or any amendment or supplement thereto); PROVIDED, HOWEVER, that in
the case of a Shelf Registration Statement, no such Holder shall be liable for
any claims hereunder in excess of the amount of net proceeds received by such
Holder from the sale of Registrable Securities pursuant to such Shelf
Registration Statement.

     (3) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
which it may have under this Section 4 to the extent that it is not materially
prejudiced by such failure as a result thereof, and in any event shall not
relieve it from liability which it may have otherwise on account of this
indemnity agreement. In the case of parties indemnified pursuant to Section 4(a)
or (b) above, counsel to the indemnified parties shall be selected by such
parties. An indemnifying party may participate at its own expense in the defense
of such action; PROVIDED, HOWEVER, that counsel to the indemnifying party shall
not (except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying parties be liable for the
fees and expenses of more than one counsel (in addition to local counsel),
separate from their own counsel, for all indemnified parties 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. No
indemnifying party shall, without the prior written consent of the indemnified
parties, 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 4 (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an
unconditional written release of each indemnified party from all liability
arising out of such litigation, 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 party.

     (4) If at any time an indemnified party shall have validly requested an
indemnifying party to reimburse the indemnified party for reasonable fees and
expenses of counsel


                                       20
<PAGE>   22


pursuant to Section 4(a), such indemnifying party agrees that it shall be liable
for any settlement of the nature contemplated by Section 4(a)(ii) effected
without its written consent if (i) such settlement is entered into more than 45
days after receipt by such indemnifying party of the aforesaid request, (ii)
such indemnifying party shall have received notice of the terms of such
settlement at least 30 days prior to such settlement being entered into and
(iii) such indemnifying party shall not have reimbursed such indemnified party
in accordance with such request prior to the date of such settlement.

     (5) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unenforceable by an indemnified party
although applicable in accordance with its terms, the Company, the Trust and the
Holders shall contribute to the aggregate losses, liabilities, claims, damages
and expenses of the nature contemplated by such indemnity agreement incurred by
the Company, the Trust and the Holders, as incurred; PROVIDED, HOWEVER, that 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 that
was not guilty of such fraudulent misrepresentation. As between the Company, the
Trust, and the Holders, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement in such proportion as shall be appropriate to reflect the
relative fault of the Company and Trust, on the one hand, and the Holders, on
the other hand, with respect to the statements or omissions which resulted in
such loss, liability, claim, damage or expense, or action in respect thereof, as
well as any other relevant equitable considerations. The relative fault of the
Company and the Trust, on the one hand, and of the Holders, 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 Company or the
Trust, on the one hand, or by or on behalf of the Holders, on the other, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company, the Trust and the
Holders of the Registrable Securities agree that it would not be just and
equitable if contribution pursuant to this Section 4 were to be determined by
pro rata allocation or by any other method of allocation that does not take into
account the relevant equitable considerations. For purposes of this Section 4,
each Affiliate of a Holder, and each partner, director, officer, employee and
Person, if any, who controls a Holder or such Affiliate within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have
the same rights to contribution as such Holder, and each director of the
Company, each Trustee of the Trust and each Person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act shall have the same rights to contribution as each of the
Company or the Trust.

     5. PARTICIPATION IN AN UNDERWRITTEN REGISTRATION. No Holder may participate
in an underwritten registration hereunder unless such Holder (a) agrees to sell
such Holder's Registrable Securities on the basis provided in the underwriting
arrangement approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements, lock-up letters and
other documents reasonably required under the terms of such underwriting
arrangements.

     6. SELECTION OF UNDERWRITERS. The Holders of Registrable Securities
covered by the Shelf Registration Statement who desire to do so may sell the
Securities covered by such Shelf


                                       21
<PAGE>   23


Registration in an underwritten offering, subject to the provisions of Section
3(m) hereof. In any such underwritten offering, the underwriter or underwriters
and manager or managers that will administer the offering will be selected by
the Holders of a majority in aggregate principal or liquidation amount, as
applicable, of the Registrable Securities included in such offering; PROVIDED,
HOWEVER, that such underwriters and managers must be reasonably satisfactory to
the Company and the Trust.

         7.  MISCELLANEOUS.

         (1) RULE 144 AND RULE 144A. For so long as the Company is subject to
the reporting requirements of Section 13 or 15 of the Exchange Act and any
Registrable Securities remain outstanding, the Company will file the reports
required to be filed by it under the Securities Act and Section 13(a) or 15(d)
of the Exchange Act and the rules and regulations adopted by the SEC thereunder;
PROVIDED, HOWEVER, that if the Company ceases to be so required to file such
reports, it will, upon the request of any Holder of Registrable Securities (a)
make publicly available such information as is necessary to permit sales of its
securities pursuant to Rule 144 under the Securities Act, (b) deliver such
information to a prospective purchaser as is necessary to permit sales of its
securities pursuant to Rule 144A under the Securities Act and (c) take such
further action that is reasonable in the circumstances, in each case, to the
extent required from time to time to enable such Holder to sell its Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (i) Rule 144 under the Securities Act, as such
rule may be amended from time to time, (ii) Rule 144A under the Securities Act,
as such rule may be amended from time to time, or (iii) any similar rules or
regulations hereafter adopted by the SEC. Upon the request of any Holder of
Registrable Securities, the Company will deliver to such Holder a written
statement as to whether it has complied with such requirements.

         (2) NO INCONSISTENT AGREEMENTS. Neither the Company nor the Trust has
entered into, nor will the Company or the Trust on or after the date of this
Agreement enter into, any agreement which is inconsistent with the rights
granted to the Holders of Registrable Securities in this Agreement or which
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's or the Trust's other issued
and outstanding securities under any such agreements.

         (3) AMENDMENTS AND WAIVERS. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given, unless the Company and the Trust have obtained the written consent of
Holders of at least a majority in aggregate principal or liquidation amount of
the outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or departure; PROVIDED that no amendment, modification or
supplement or waiver or consent to the departure with respect to the provisions
of Section 4 hereof shall be effective as against any Holder of Registrable
Securities unless consented to in writing by such Holder of Registrable
Securities. Notwithstanding the foregoing sentence, (i) this Agreement may be
amended, without the consent of any Holder of Registrable Securities, by written
agreement signed by the Company, the Trust and the Initial Purchaser, to cure
any ambiguity, correct or supplement any provision of this Agreement that may be
inconsistent with any other provision of this Agreement or to make any other
provisions with respect to matters or questions arising under this Agreement
which shall not be inconsistent with other provisions of this Agreement, (ii)
this Agreement may be


                                       22
<PAGE>   24


amended, modified or supplemented, and waivers and consents to departures from
the provisions hereof may be given, by written agreement signed by the Company,
the Trust and the Initial Purchaser to the extent that any such amendment,
modification, supplement, waiver or consent is, in their reasonable judgment,
necessary or appropriate to comply with applicable law (including any
interpretation of the Staff of the SEC) or any change therein and (iii) to the
extent any provision of this Agreement relates to the Initial Purchaser, such
provision may be amended, modified or supplemented, and waivers or consents to
departures from such provisions may be given, by written agreement signed by the
Initial Purchaser, the Company and the Trust. Each Holder of Registrable
Securities shall be bound by any amendment or waiver effected pursuant to this
Section 7(c), whether or not any notice, writing or marking indicating such
amendment or waiver appears on such security or is delivered to such Holder.

         (4) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company or the Trust by means of a notice given in accordance with the
provisions of this Section 7(d), which address initially is, with respect to the
Initial Purchaser, the address set forth in the Purchase Agreement; and (ii) if
to the Company or the Trust, initially at the Company's address set forth in the
Purchase Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 7(d).

         All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next Business Day, if timely delivered to an air courier guaranteeing
overnight delivery.

         Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee, at the
address specified in the Indenture.

         (5) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of the Initial
Purchaser, including, without limitation and without the need for an express
assignment, subsequent Holders; PROVIDED, HOWEVER, that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement, the Declaration
or the Indenture. If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person
shall be conclusively deemed to have agreed to be bound by and to perform all of
the terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

         (6) THIRD PARTY BENEFICIARIES. Each Holder and any Participating
Broker-Dealer shall be third party beneficiaries of the agreements made
hereunder among the Initial Purchaser, the Company and the Trust, and the
Initial Purchaser shall have the right to enforce such agreements directly to
the extent it deems such enforcement necessary or advisable to protect its
rights or the rights of Holders hereunder.

         (7) COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         (8) HEADINGS. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         (9) GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE IN
THE STATE OF NEW YORK. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, AND
THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY
PROVISIONS RELATING TO CONFLICTS OF LAWS. EACH OF THE PARTIES HERETO AGREES TO
SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN
ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF
THE MATTERS CONTEMPLATED HEREBY, IRREVOCABLY WAIVES ANY DEFENSE OF LACK OF
PERSONAL JURISDICTION AND IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY
SUIT, ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT. EACH
OF THE PARTIES HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY OBJECTION WHICH IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF VENUE OF SUCH SUIT, ACTION OR PROCEEDING BROUGHT
IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT
IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

         (10) SEVERABILITY. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

         (11) SECURITIES HELD BY THE COMPANY, THE TRUST OR ITS AFFILIATES.
Whenever the consent or approval of Holders of a specified percentage of
Registrable Securities is required hereunder, Registrable Securities held by the
Company, the Trust or any Affiliates shall not be counted in determining whether
such consent or approval was given by the Holders of such required percentage.

                      COMMON SECURITIES GUARANTEE AGREEMENT


         This COMMON SECURITIES GUARANTEE AGREEMENT (the "Common Securities
Guarantee"), dated as of October 18, 1999, is executed and delivered by
BANCFIRST OHIO CORP., an Ohio corporation (the "Guarantor"), for the benefit of
the Holders (as defined herein) from time to time of the Common Securities (as
defined herein) of BFOH CAPITAL TRUST I, a Delaware business trust (the
"Issuer").

         WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of October 18, 1999, by and among the Trustees of the
Issuer named therein, the Guarantor, as sponsor, and the holders from time to
time of undivided beneficial interests in the assets of the Issuer, the Issuer
is issuing on the date hereof 619 common securities having an aggregate
liquidation amount of Six Hundred Nineteen Thousand Dollars ($619,000), to meet
the capital requirements of the Trust; such common securities being designated
the 9.875% Common Securities (the "Common Securities").

         WHEREAS, as incentive for the Holders to purchase the Common
Securities, the Guarantor desires irrevocably and unconditionally to agree, to
the extent set forth in this Common Securities Guarantee, to pay the Guarantee
Payments (as defined herein) to the Holders of the Common Securities and to make
certain other payments on the terms and conditions set forth herein; and

         WHEREAS, the Guarantor is also executing and delivering the Series A
Capital Securities Guarantee Agreement, dated as of October 18, 1999 (the
"Series A Capital Securities Guarantee"), for the benefit of the holders of the
Series A Capital Securities (as defined in the Declaration) and upon
consummation of the Exchange Offer (as defined in the Declaration) will execute
and deliver the Series B Capital Securities Guarantee Agreement (the "Series B
Capital Securities Guarantee") for the benefit of the holders of the Series B
Capital Securities (as defined in the Declaration); it being understood that if
an Event of Default (as defined in the Declaration) has occurred and is
continuing, the rights of Holders of the Common Securities to receive Guarantee
Payments under this Common Securities Guarantee are subordinated, to the extent
and in the manner set forth herein, to the rights of holders of Capital
Securities (as defined in the Declaration) to receive Guarantee Payments under
the Series A Capital Securities Guarantee and the Series B Capital Securities
Guarantee, as the case may be.

         NOW, THEREFORE, in consideration of the purchase by each Holder of the
Common Securities, which purchase the Guarantor hereby acknowledges shall
benefit the Guarantor, the Guarantor executes and delivers this Common
Securities Guarantee for the benefit of the Holders.

Guarantee; and

<PAGE>   6


of the Common Securities or the extension of time for the performance of any
other obligation under, arising out of, or in connection with, the Common

any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 2.4  RIGHTS OF HOLDERS

SECTION 2.5  GUARANTEE OF PAYMENT

         This Common Securities Guarantee creates a guarantee of payment and not
of collection.

SECTION 2.6  SUBROGATION

         The Guarantor shall be subrogated to all (if any) rights of the Holders
of the Common Securities against the Issuer in respect of any amounts paid to
such Holders by the Guarantor under this Common Securities Guarantee; PROVIDED,

mandatory provisions of law) be entitled to enforce or exercise any rights which
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all


                                       5

time of any such payment, any amounts are due and unpaid under this Common

Securities Guarantee notwithstanding the occurrence of any event referred to in

extension thereof, shall have commenced and be continuing.

SECTION 3.2  RANKING

         This Common Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (i) subordinate and junior in right of
payment to the Senior Indebtedness (as defined in the Indenture), to the same
extent and in the same manner that the Debentures are subordinated to the Senior
Indebtedness pursuant to the Indenture, it being understood that the terms of

under this Common Securities Guarantee as if such Article XV were set forth
herein in full, (ii) pari passu with the most senior preferred or preference

under this Common Securities Guarantee.

                                --------------------

Ladies and Gentlemen:

        We have acted as special Delaware counsel for BFOH Capital Trust I, a
Delaware business trust (the "Trust"), for purposes of giving the opinions set
forth herein. This opinion letter is being furnished to you at your request.

        For purposes of giving the opinions set forth below, our examination of
documents has been limited to the examination of originals or copies furnished
to us of the following:

1999, between BancFirst Ohio Corp. (the "Company") and the trustee of the Trust
named therein;

        (b) The Certificate of Trust of the Trust, as filed in the office of the
Secretary of State of the State of Delaware (the "Secretary of State") on

of October 18, 1999 (the "Declaration"), among the Company, as Sponsor, the
trustees of the Trust named therein (the "Trustees") and the holders, from time
to time, of undivided beneficial interests in the assets of the Trust;

        (d) The Registration Statement on Form ________ (Registration No.
________ ) (the "Registration Statement"), including a prospectus (the
"Prospectus"), relating to the 9.875% Capital Securities, Series B (Liquidation
Amount $1,000 per Capital Security) of the Trust representing undivided
preferred beneficial interests in the assets of the Trust (each, an "Exchange
Capital Security" and collectively, the "Exchange Capital Securities"), as filed
with the Securities and Exchange Commission on or about February __, 2000; and

        (e) A Certificate of Good Standing for the Trust, dated February __,
2000, obtained from the Secretary of State.

        Unless otherwise defined herein, all capitalized terms used in this
opinion letter shall have the respective meanings provided in the Declaration,
except that reference herein to any document shall mean such document as in
effect on the date hereof.

        For the purposes of this opinion letter, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that
bears upon or is inconsistent with or contrary to the opinions stated herein. We
have conducted no factual investigation of our own but rather have relied solely
upon the foregoing documents, the statements and information set forth therein
and the additional matters recited or assumed herein, all of which we have
assumed to be true, complete and accurate in all material respects.

        With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

        For purposes of this opinion letter, we have assumed (i) that the
Declaration constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation, and termination of the Trust, and that the Declaration and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation, due formation or
due organization, as the case may be, and valid existence in good standing of
each party to the documents examined by us under the laws of the jurisdiction
governing its creation, formation or organization, (iii) the legal capacity of
each natural person who is a party to the documents examined by us, (iv) that
each of the parties to the documents examined by us has all requisite power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) that each of the parties to the documents examined by us has duly
authorized, executed and delivered such documents, (vi) the receipt by each
Person to whom an Exchange Capital Security is to be issued by the Trust (the
"Exchange Capital Security Holders") of an appropriate certificate for such
Exchange Capital Security and the exchange by each Exchange

Capital Security Holder of its validly issued Series A Capital Securities
accepted for exchange for the Exchange Capital Securities to be issued to it, in
accordance with the Declaration and the Registration Statement, and (vii) that
the Exchange Capital Securities are issued to the Exchange Capital Security
Holders in accordance with the Declaration and the Registration Statement. We
have not participated in the preparation of the Registration Statement and
assume no responsibility for its contents.

        The opinions in this letter are limited to the laws of the State of
Delaware (other than the securities laws of the State of Delaware) and we have
not considered and express no opinion on the effect of or concerning matters
involving the laws of any other jurisdiction, or rules, regulations, orders and
judicial and administrative decisions relating to such laws, including, without
limitation, the federal laws of the United States of America.

        Based upon the foregoing, and subject to the assumptions,
qualifications, limitations and exceptions set forth herein, we are of the
opinion that:

        1. The Trust has been duly formed and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, 12 Del. C.
Section 3801, et seq.

        2. The Exchange Capital Securities will represent valid and, subject to
the qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

        3. The Exchange Capital Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Exchange Capital
Security Holders may be obligated to make payments and provide indemnity and/or
security as set forth in the Declaration.

        We consent to the filing of this opinion letter with the Securities and
Exchange Commission as an exhibit to the Registration Statement. In giving the
foregoing consent, we do not thereby admit that we come within the category of
Persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended, or the rules and regulations of the

               account, if any, to be provided for the Preferred Stock of such

               such circumstances and on such conditions as the Board of
               Directors may determine.

          (c) (1) After the requirements with respect to preferential dividends
          on the Preferred Stock (fixed in accordance with the provisions of
          section (b) of this Article FOURTH), if any, shall have been met and
          after the Corporation shall have complied with all the requirements,

          provisions of section (b) of this Article FOURTH), and subject further
          to any conditions which may be fixed in accordance with the provisions
          of section (b) of this Article FOURTH, then and not otherwise the
          holders of Common Stock shall be entitled to receive such dividends as

               liquidation, distribution or sale of assets, dissolution or
               winding-up, of the Corporation, the holders of the Common Stock
               shall be entitled to receive all of the remaining assets of the
               Corporation, tangible and intangible, of whatever kind available
               for distribution to stockholders ratably in proportion to the
               number of shares of Common Stock held by them respectively.
               (3) Except as may otherwise be required by law or by the
               provisions of such resolution or resolutions as may be adopted by
               the Board of Directors pursuant to section (b) of this Article
               FOURTH, each holder of Common Stock shall have one vote in
               respect of each share of Common Stock held on all matters voted

                                       6
<PAGE>   20

          the Corporation shall have any preemptive right to purchase or
          subscribe for any unissued stock of any class or series or any
          additional shares of any class or series to be issued by reason of any
          increase of the authorized capital stock of the Corporation of any
          class or series, or bonds, certificates of indebtedness, debentures or
          other securities convertible into or exchangeable for stock of the
          Corporation of any class or series, or carrying any right to purchase
          stock of any class or series, but any such unissued stock, additional
          authorized issue of shares of any class or series of stock or
          securities convertible into or exchangeable for stock, or carrying any
          right to purchase stock, may be issued and disposed of pursuant to
          resolution of the Board of Directors to such persons, firms,
          corporations or associations, whether such holders or others, and upon
          such terms as may be deemed advisable by the Board of Directors in the
          exercise of its sole discretion.

          (e) The relative powers, preferences and rights of each series of
          Preferred Stock in relation to the relative powers, preferences and
          rights of each other series of Preferred Stock shall, in each case, be
          as fixed from time to time by the Board of Directors in the resolution
          or resolutions adopted pursuant to authority granted in section (b) of
          this Article FOURTH and the consent, by class or series vote or
          otherwise, of the holders of such of the series of Preferred Stock as
          are from time to time outstanding shall not be required for the
          issuance by the Board of Directors of any other series of Preferred
          Stock whether or not the powers, preferences and rights of such other
          series shall be fixed by the Board of Directors as senior to, or on a
          parity with, the powers, preferences and rights of such outstanding
          series, or any of them; provided, however, that the Board of Directors
          may provide in the resolution or resolutions as to any series of
          Preferred Stock adopted pursuant to section (b) of this Article FOURTH
          that the consent of the holders of a majority (or such greater
          proportion as shall be therein fixed) of the outstanding shares of
          such series voting thereon shall be required for the issuance of any
          or all other series of Preferred Stock.

          (f) Subject to the provisions of section (e), shares of any series of
          Preferred Stock may be issued from time to time as the Board of
          Directors of the Corporation shall determine and on such terms and for
          such consideration as shall be fixed by the Board of Directors.

          (g) Shares of Common Stock may be issued from time to time as the
          Board of Directors of the Corporation shall determine and on such
          terms and for such consideration as shall be fixed by the Board of
          Directors.

          (h) The authorized amount of shares of Common Stock and of Preferred
          Stock may, without a class or series vote, be increased or decreased
          from time to time by the affirmative vote of the holders of a majority
          of the stock of the Corporation entitled to vote thereon.

          FIFTH: - (a) The business and affairs of the Corporation shall be
          conducted and managed by a Board of Directors. The number of directors
          constituting the entire Board shall be


                                       7
<PAGE>   21


          not less than five nor more than twenty-five as fixed from time to
          time by vote of a majority of the whole Board, provided, however, that
          the number of directors shall not be reduced so as to shorten the term
          of any director at the time in office, and provided further, that the
          number of directors constituting the whole Board shall be twenty-four
          until otherwise fixed by a majority of the whole Board.

          (b) The Board of Directors shall be divided into three classes, as
          nearly equal in number as the then total number of directors
          constituting the whole Board permits, with the term of office of one
          class expiring each year. At the annual meeting of stockholders in
          1982, directors of the first class shall be elected to hold office for
          a term expiring at the next succeeding annual meeting, directors of
          the second class shall be elected to hold office for a term expiring
          at the second succeeding annual meeting and directors of the third
          class shall be elected to hold office for a term expiring at the third
          succeeding annual meeting. Any vacancies in the Board of Directors for
          any reason, and any newly created directorships resulting from any
          increase in the directors, may be filled by the Board of Directors,
          acting by a majority of the directors then in office, although less
          than a quorum, and any directors so chosen shall hold office until the
          next annual election of directors. At such election, the stockholders
          shall elect a successor to such director to hold office until the next
          election of the class for which such director shall have been chosen
          and until his successor shall be elected and qualified. No decrease in
          the number of directors shall shorten the term of any incumbent
          director.

          (c) Notwithstanding any other provisions of this Charter or Act of
          Incorporation or the By-Laws of the Corporation (and notwithstanding
          the fact that some lesser percentage may be specified by law, this
          Charter or Act of Incorporation or the By-Laws of the Corporation),
          any director or the entire Board of Directors of the Corporation may
          be removed at any time without cause, but only by the affirmative vote
          of the holders of two-thirds or more of the outstanding shares of
          capital stock of the Corporation entitled to vote generally in the
          election of directors (considered for this purpose as one class) cast
          at a meeting of the stockholders called for that purpose.

          (d) Nominations for the election of directors may be made by the Board
          of Directors or by any stockholder entitled to vote for the election
          of directors. Such nominations shall be made by notice in writing,
          delivered or mailed by first class United States mail, postage
          prepaid, to the Secretary of the Corporation not less than 14 days nor
          more than 50 days prior to any meeting of the stockholders called for
          the election of directors; provided, however, that if less than 21
          days' notice of the meeting is given to stockholders, such written
          notice shall be delivered or mailed, as prescribed, to the Secretary
          of the Corporation not later than the close of the seventh day
          following the day on which notice of the meeting was mailed to
          stockholders. Notice of nominations which are proposed by the Board of
          Directors shall be given by the Chairman on behalf of the Board.

          (e) Each notice under subsection (d) shall set forth (i) the name,
          age, business address


                                       8

          and, if known, residence address of each nominee proposed in such
          notice, (ii) the principal occupation or employment of such nominee
          and (iii) the number of shares of stock of the Corporation which are
          beneficially owned by each such nominee.

          (f) The Chairman of the meeting may, if the facts warrant, determine
          and declare to the meeting that a nomination was not made in
          accordance with the foregoing procedure, and if he should so
          determine, he shall so declare to the meeting and the defective
          nomination shall be disregarded.

          (g) No action required to be taken or which may be taken at any annual
          or special meeting of stockholders of the Corporation may be taken
          without a meeting, and the power of stockholders to consent in
          writing, without a meeting, to the taking of any action is
          specifically denied.

          SIXTH: - The Directors shall choose such officers, agents and servants
          as may be provided in the By-Laws as they may from time to time find
          necessary or proper.

          powers, rights and privileges as may be conferred upon corporations
          organized under the Act entitled "An Act Providing a General

          exercise all of the powers of the Board of Directors in the management
          of the business and affairs of the Corporation, and shall have power
          to authorize the seal of the Corporation to be affixed to all papers
          which may require it.

          a vote of the majority of the entire Board. The stockholders may make,

          be adopted only by the affirmative vote of the holders of two-thirds
          or more of the

not be exclusive of any other rights which such person may have or hereafter
acquire under any statute, provision of the Charter or Act of Incorporation,
these By-Laws, agreement, vote of stockholders or disinterested Directors or
otherwise.

meaning given them in the Prospectus (as defined below). As used herein, the
term "Holder" means a holder of Original Capital Securities, including any

the Depository Trust Company ("DTC") whose name appears on a security position
listing as the owner of the Original Capital Securities. As used herein,
"Certificates" means the physical certificates representing Original Capital
Securities.

         To participate in the Exchange Offer (as defined below), Holders must
tender by (i) book-entry transfer pursuant to the procedures set forth in the
Prospectus under "The Exchange Offer - Procedures for Tendering Original Capital
Securities," or (ii) forwarding Certificates herewith. This Letter of
Transmittal is to be completed by holders of Original Capital Securities either
if (i) Original Capital Securities are to be forwarded herewith or (ii) tenders

executed, with any required signature guarantees, and any other documents

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

         1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED
DELIVERY PROCEDURES. This Letter of Transmittal is to be completed either if (a)
Certificates are to be forwarded herewith or (b) tenders are to be made pursuant
to the procedures for tender by book-entry transfer set forth in "The Exchange
Offer Procedures for Tendering Original Capital Securities" in the Prospectus.
Certificates, or timely confirmation of a book-entry transfer of such Original
Capital Securities into the Exchange Agent's account at DTC, as well as this
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees, and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
at its address set forth herein on or prior to the Expiration Date. Tenders by
book-entry transfer also may be made by delivering an Agents Message in lieu of
this Letter of Transmittal. Original Capital Securities may be tendered in whole
or in part in the Liquidation Amount of $100,000 (100 Capital Securities) and
integral multiples of $1,000 in excess thereof, provided that, if any Original
Capital Securities are tendered for exchange in part, the untendered Liquidation
Amount thereof must be $100,000 (100 Capital Securities) or any integral
multiple of $1,000 in excess thereof.

         Holders who wish to tender their Original Capital Securities and (i)
whose Original Capital Securities are not immediately available or (ii) who
cannot deliver their Original Capital Securities, this Letter of Transmittal and
all other required documents to the Exchange Agent on or prior to the Expiration
Date or (iii) who cannot complete the procedures for delivery by book-entry
transfer on or prior to the Expiration Date, may tender their Original Capital
Securities by properly completing and duly executing a Notice of Guaranteed
Delivery pursuant to the guaranteed delivery procedures set forth in "The
Exchange Offer -- Procedures for Tendering Original Capital Securities" in the
Prospectus. Pursuant to such procedures: (i) such tender must be made by or
through an Eligible Institution (as defined below); (ii) a properly completed
and duly executed Notice of Guaranteed Delivery, substantially in the form
accompanying this Letter of Transmittal, must be received by the Exchange Agent
on or prior to the Expiration Date; and (iii) the Certificates (or a "book-entry
confirmation" (as defined in the Prospectus)) representing all tendered Original
Capital Securities, in proper form for transfer, together with a Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees and any other documents required by this
Letter of Transmittal, must be received by the Exchange Agent within three New
York Stock Exchange, Inc. trading days after the date of execution of such
Notice of Guaranteed Delivery, all as provided in "The Exchange Offer --
Procedures for Tendering Original Capital Securities" in the Prospectus.

         The Notice of Guaranteed Delivery may be delivered by hand or
transmitted by facsimile or mail to the Exchange Agent, and must include a
guarantee by an Eligible Institution in the form set forth in such Notice. For
Original Capital Securities to be properly tendered pursuant to the guaranteed
delivery procedure, the Exchange Agent must receive a Notice of Guaranteed
Delivery on or prior to the Expiration Date. As used herein and in the
Prospectus, "Eligible Institution" means a firm or other entity identified in
Rule 17Ad-15 under the Exchange Act as "an eligible guarantor institution,"
including (as such terms are defined therein) (i) a bank; (ii) a broker, dealer,
municipal securities broker or dealer or government securities broker or dealer;
(iii) a credit union; (iv) a national securities exchange, registered securities
association or clearing agency; or (v) a savings association that is a
participant in a Securities Transfer Association.

         THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, OR OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

         Neither the Company nor the Trust will accept any alternative,
conditional or contingent tenders. Each tendering holder, by execution of a
Letter of Transmittal (or facsimile thereof), waives any right to receive any
notice of the acceptance of such tender.


<PAGE>   10

         2. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of
Transmittal is required if:

         (i) this Letter of Transmittal is signed by the registered holder
(which term, for purposes of this document, shall include any participant in DTC
whose name appears on a DTC security position listing as the owner of the
Original Capital Securities) of Original Capital Securities tendered herewith,
unless such holder(s) has completed either the box entitled "Special Issuance
Instructions" or the box entitled "Special Delivery Instructions" above, or

         (ii) such Original Capital Securities are tendered for the account of a
firm that is an Eligible Institution.

         In all other cases, an Eligible Institution must guarantee the
signature(s) on this Letter of Transmittal. See Instruction 5.

         3. INADEQUATE SPACE. If the space provided in the box captioned
"Description of Original Capital Securities Tendered" is inadequate, the
Certificate number(s) and/or the aggregate liquidation amount of the Original
Capital Securities and any other required information should be listed on a
separate signed schedule which is attached to this Letter of Transmittal.

         4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS. Tenders of Original Capital
Securities will be accepted only in the Liquidation Amount of $100,000 (100
Capital Securities) and integral multiples of $1,000 in excess thereof, provided
that if any Original Capital Securities are tendered for exchange in part, the
untendered Liquidation Amount thereof must be $100,000 (100 Capital Securities)
or any integral multiple of $1,000 in excess thereof. If less than all the
Original Capital Securities evidenced by any Certificate submitted are to be
tendered, fill in the liquidation amount of Original Capital Securities which
are to be tendered in the box entitled "Liquidation Amount of Original Capital
Securities Tendered (if less than all tendered)." In such case, new
Certificate(s) for the remainder of the Original Capital Securities that were
evidenced by your old Certificate(s) will be sent to the holder of the Original
Capital Securities, promptly after the Expiration Date, unless the appropriate
boxes of this Letter of Transmittal are completed. All Original Capital
Securities represented by Certificates delivered to the Exchange Agent will be
deemed to have been tendered unless otherwise indicated.

         Except as otherwise provided herein, tenders of Original Capital
Securities may be withdrawn at any time on or prior to the Expiration Date. In
order for a withdrawal to be effective on or prior to that time, a written or
facsimile transmission of such notice of withdrawal must be timely received by
the Exchange Agent at its address set forth above or in the Prospectus on or
prior to the Expiration Date. Any such notice of withdrawal must specify the
name of the person who tendered the Original Capital Securities to be withdrawn,
the aggregate Liquidation Amount of Original Capital Securities to be withdrawn,
and (if Certificates for Original Capital Securities have been tendered) the
name of the registered holder of the Original Capital Securities as set forth on
the Certificate for the Original Capital Securities, if different from that of
the person who tendered such Original Capital Securities. If Certificates for
the Original Capital Securities have been delivered or otherwise identified to
the Exchange Agent, then prior to the physical release of such Certificates for
the Original Capital Securities, the tendering holder must submit the serial
numbers shown on the particular Certificates for the Original Capital Securities
to be withdrawn and the signature on the notice of withdrawal must be guaranteed
by an Eligible Institution, except in the case of Original Capital Securities
tendered for the account of an Eligible Institution. If Original Capital
Securities have been tendered pursuant to the procedures for book-entry transfer
set forth in "The Exchange Offer -- Procedures for Tendering Original Capital
Securities," the notice of withdrawal must specify the name and number of the
account at DTC to be credited with the withdrawal of Original Capital
Securities, in which case a notice of withdrawal will be effective if delivered
to the Exchange Agent by written or facsimile transmission on or prior to the
Expiration Date. Withdrawals of tenders of Original Capital Securities may not
be rescinded. Original Capital Securities properly withdrawn will not be deemed
validly tendered for purposes of the Exchange Offer, but may be retendered at
any subsequent time on or prior to the Expiration Date by following any of the
procedures described herein and in the Prospectus under "The Exchange Offer --
Procedures for Tendering Original Capital Securities."

         All questions as to the validity, form and eligibility (including time
of receipt) of such withdrawal notices will be determined by the Company and the
Trust, in their sole discretion, whose determination shall be final and binding
on all parties. None of the Company, the Trust, any affiliates or assigns of the
Company or the Trust, the Exchange Agent nor any other person shall be under any
duty to give any notification of any irregularities in any

<PAGE>   11



notice of withdrawal or incur any liability for failure to give any such
notification. Any Original Capital Securities which have been tendered but which
are withdrawn will be returned or transferred by book-entry, as the case may be,
to the holder thereof without cost to such holder promptly after withdrawal.

         5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS.
If this Letter of Transmittal is signed by the registered holder(s) of the
Original Capital Securities tendered hereby, the signature(s) must correspond
exactly with the name(s) as written on the face of the Certificate(s) or as
recorded on DTC's book-entry transfer facility system, as the case may be,
without alteration, enlargement or any change whatsoever.

         If any of the Original Capital Securities tendered hereby are owned of
record by two or more joint owners, all such owners must sign this Letter of
Transmittal.

         If any tendered Original Capital Securities are registered in different
name(s) on several Certificates, it will be necessary to complete, sign and
submit as many separate Letters of Transmittal (or facsimiles thereof) as there
are different registrations of Certificates. If any tendered Original Capital
Securities are registered in different names in several book-entry accounts,
proper procedures for book-entry transfer must be followed for each account.

         If this Letter of Transmittal or any Certificates or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing and must submit proper
evidence satisfactory to the Company and the Trust, in their sole discretion, of
such persons' authority to so act.

         When this Letter of Transmittal is signed by the registered holder(s)
of the Original Capital Securities listed and transmitted hereby, no
endorsement(s) of Certificate(s) or separate bond power(s) are required unless
Exchange Capital Securities are to be issued in the name of a person other than
the registered holder(s). Signature(s) on such Certificate(s) or bond power(s)
must be guaranteed by an Eligible Institution.

         If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Original Capital Securities listed, the Certificates
must be endorsed or accompanied by appropriate bond powers, signed exactly as
the name or names of the registered holder(s) appear(s) on the Certificates, and
also must be accompanied by such opinions of counsel, certifications and other
information as the Company, the Trust and the Exchange Agent may require in
accordance with the restrictions on transfer applicable to the Original Capital
Securities. Signatures on such Certificates or bond powers must be guaranteed by
an Eligible Institution.

         6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If Exchange Capital
Securities are to be issued in the name of a person other than the signer of
this Letter of Transmittal, or if Exchange Capital Securities are to be sent to
someone other than the signer of this Letter of Transmittal or to an address
other than that shown above, the appropriate boxes on this Letter of Transmittal
should be completed. Certificates for Original Capital Securities not exchanged
will be returned, if evidenced by Certificates, by mail or, if tendered by
book-entry transfer, by crediting the account indicated above maintained at DTC.
See Instruction 4.

         7. IRREGULARITIES. The Company and the Trust will determine, in their
sole discretion, all questions as to the form of documents, validity,
eligibility (including time of receipt) and acceptance for exchange of any
tender of Original Capital Securities, which determination shall be final and
binding on all parties. The Company and the Trust reserve the absolute right to
reject any and all tenders determined by either of them not to be in proper form
or the acceptance of which, or exchange for which, may, in the view of counsel
to the Company and the Trust, be unlawful. The Company and the Trust also
reserve the absolute right, subject to applicable law, to waive any of the
conditions of the Exchange Offer set forth in the Prospectus under "The Exchange
Offer -- Certain Conditions to the Exchange Offer" or any conditions or
irregularity in any tender of Original Capital Securities of any particular
holder whether or not similar conditions or irregularities are waived in the
case of other holders.

         The Company's and the Trust's interpretation of the terms and
conditions of the Exchange Offer (including this Letter of Transmittal and the
instructions hereto) will be final and binding. No tender of Original Capital
Securities will be deemed to have been validly made until all irregularities
with respect to such tender have been

<PAGE>   12


cured or waived. None of the Company, the Trust, any affiliates or assigns of
the Company or the Trust, the Exchange Agent, nor any other person shall be
under any duty to give notification of any irregularities in tenders or incur
any liability for failure to give such notification.

         8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions
and requests for assistance may be directed to the Exchange Agent at its address
and telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, the Notice of Guaranteed Delivery and the
Letter of Transmittal may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.

         9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal
income tax law, a holder whose tendered Original Capital Securities are accepted
for exchange is required to provide the Exchange Agent with such holder's
correct taxpayer identification number ("TIN") on Substitute Form W-9 below. If
the Exchange Agent is not provided with the correct TIN, the Internal Revenue
Service (the "IRS") may subject the holder or other payee to a $50 penalty. In
addition, payments to such holders or other payees with respect to Original
Capital Securities exchanged pursuant to the Exchange Offer may be subject to
31% backup withholding.

         The box in Part 2 of the Substitute Form W-9 may be checked if the
tendering holder has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future. If the box in Part 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-9.
If the holder furnishes the Exchange Agent with its TIN within 60 days after the
date of the Substitute Form W-9, the amounts retained during the 60 day period
will be remitted to the holder and no further amounts shall be retained or
withheld from payments made to the holder thereafter. If, however, the holder
has not provided the Exchange Agent with its TIN within such 60 day period,
amounts withheld will be remitted to the IRS as backup withholding. In addition,
31% of all payments made thereafter will be withheld and remitted to the IRS
until a correct TIN is provided.

         The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Original Capital Securities or of the last transferee appearing on the
transfers attached to, or endorsed on, the Original Capital Securities. If the
Original Capital Securities are registered in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which number to report.

         Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the face
thereof, to avoid possible erroneous backup withholding. A foreign person may
qualify as an exempt recipient by submitting a properly completed IRS Form W-8,
signed under penalties of perjury, attesting to that holder's exempt status.
Please consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
holders are exempt from backup withholding.

         Backup withholding is not an additional U.S. Federal income tax.
Rather, the U.S. Federal income tax liability of a person subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained.

         10. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s)
representing Original Capital Securities have been lost, destroyed or stolen,
the holder should promptly notify the Exchange Agent. The holder will then be
instructed as to the steps that must be taken in order to replace the
Certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, destroyed or stolen
Certificate(s) have been followed.

         11. SECURITY TRANSFER TAXES. Holders who tender their Original Capital
Securities for exchange will not be obligated to pay any transfer taxes in
connection therewith. If, however, Exchange Capital Securities are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Original Capital Securities tendered, or if a transfer
tax is imposed for any reason other than the exchange of Original Capital
Securities in connection with the Exchange Offer, then the amount of any such
transfer tax (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder.

         12. WAIVER OF CONDITIONS. The Company and the Trust reserve the
absolute right to waive satisfaction of any or all conditions enumerated in the
Prospectus.

          IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF)
              AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY
             THE EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE.

                                                               ___________, 2000




Wilmington Trust Company,
as Property Trustee of BFOH Capital Trust I
Corporate Trust Administration
Rodney Square North
1100 North Market Street
Wilmington, Delaware 19890


Ladies and Gentlemen:

         BFOH Capital Trust I, a business trust formed under the laws of the
State of Delaware (the "Trust") proposes to make an offer (the "Exchange Offer")
to exchange any and all of its outstanding 9.875% Capital Securities, Series A
(Liquidation Amount $1,000 per Capital Security) (the "Original Capital
Securities") for its 9.875% Capital Securities, Series B (Liquidation Amount
$1,000 per Capital Security) (the "Exchange Capital Securities"). All of the
beneficial interests represented by common securities of the Trust are owned by
BancFirst Ohio Corp., an Ohio corporation (the "Corporation"). The terms and
conditions of the Exchange Offer as currently contemplated are set forth in a
prospectus, dated ___________, 2000 (as the same may be amended or supplemented
from time to time, the "Prospectus"), to be distributed to all record holders of
the Original Capital Securities. A copy of the Prospectus is attached hereto as
Exhibit A. The Original Capital Securities and the Exchange Capital Securities
are collectively referred to herein as the "Securities." Capitalized terms used
but not defined herein shall have the same meaning given them in the Prospectus.

         A copy of each of the form of the Letter of Transmittal, the form of
the Notice of Guaranteed Delivery, the form of letter to brokers and the form of
letter to clients to be used in connection with the Exchange Offer are attached
hereto as Exhibit B.

         The Trust hereby appoints the Property Trustee to act as exchange agent
(the "Exchange Agent") in connection with the Exchange Offer. References
hereinafter to "you" shall refer to the Property Trustee.

         The Exchange Offer is expected to be commenced by the Trust on or about
___________, 2000. The Letter of Transmittal accompanying the Prospectus (or in
the case of book-entry securities, the ATOP system) is to be used by the holders
of the Original Capital Securities to accept the Exchange Offer and contains
instructions with respect to (i) the delivery of certificates for


<PAGE>   2



Wilmington Trust Company

___________, 2000



Original Capital Securities tendered in connection therewith and (ii) the
book-entry transfer of Securities to the Exchange Agent's account.

         The Exchange Offer shall expire at 5:00 P.M., New York City time, on
___________, 2000 or on such later date or time to which the Trust may extend
the Exchange Offer (the "Expiration Date"). Subject to the terms and conditions
set forth in the Prospectus, the Trust expressly reserves the right to extend
the Exchange Offer from time to time by giving oral (to be confirmed in writing)
or written notice to you before 9:00 A.M., New York City time, on the Business
Day following the previously scheduled Expiration Date.

         The Trust expressly reserves the right to amend or terminate the
Exchange Offer, and not to accept for exchange any Original Capital Securities
not theretofore accepted for exchange, upon the occurrence of any of the
conditions of the Exchange Offer specified in the Prospectus under the caption
"The Exchange Offer -- Conditions to the Exchange Offer." The Trust will give
you prompt oral (confirmed in writing) or written notice of any amendment,
termination or nonacceptance of Original Capital Securities.

         In carrying out your duties as Exchange Agent, you are to act in
accordance with the following instructions:

         1.    You will perform such duties and only such duties as are
specifically set forth in the section of the Prospectus captioned "The Exchange
Offer" or as specifically set forth herein.

         2.    You will establish an account with respect to the Original
Capital Securities at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Exchange Offer as soon as practicable, and any
financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of the Original Capital
Securities by causing the Book-Entry Transfer Facility to transfer such Original
Capital Securities into your account in accordance with the Book-Entry Transfer
Facility's procedure for such transfer.

         3.    You are to examine each of the Letters of Transmittal and
certificates for Original Capital Securities (or confirmation of book-entry
transfer into your account at the Book-Entry Transfer Facility) and any other
documents received by you from or for holders of the Original Capital Securities
to ascertain whether: (i) on their face the Letters of Transmittal and any such
other documents are duly executed and properly completed in accordance with
instructions set forth therein and (ii) the Original Capital Securities have
otherwise been properly tendered. In each case where the Letter of Transmittal
or any other document has been improperly completed or executed or any of the
certificates for Original Capital Securities are not in proper form for transfer
or some other irregularity in connection with the acceptance of the Exchange
Offer exists, you will endeavor to inform such tendering holders of the need for
fulfillment of all requirements and to take any other action as may be necessary
or advisable to cause such irregularity to be corrected.

         4.    With the approval of any Administrative Trustee of the Trust or
any person designated in writing by the Corporation (a "Designated Officer")
(such approval, if given orally, to be confirmed in writing) or any other party
designated by any such Administrative Trustee or Designated Officer in writing,
you are authorized to waive any irregularities in connection with any tender of
Original Capital Securities pursuant to the Exchange Offer.

         5.    Tenders of Original Capital Securities may be made only as set
forth in the Letter of Transmittal and in the section of the Prospectus
captioned "The Exchange Offer--Procedures for Tendering Original Capital
Securities," and Original Capital Securities shall be considered properly
tendered to you only when tendered in accordance with the procedures set forth
therein.

         Notwithstanding the provisions of this paragraph 5, Original Capital
Securities that any Administrative Trustee of the Trust or Designated Officer of
the Corporation shall approve as having been properly tendered shall be
considered to be properly tendered. Such approval, if given orally, shall be
confirmed in writing.

         6.    You shall advise the Trust and the Corporation with respect to
any Original Capital Securities received subsequent to the Expiration Date and
accept their instructions with respect to disposition of such Original Capital
Securities.

         7.    You shall accept tenders:

          (a)  in cases where the Original Capital Securities are registered in
               two or more names only if signed by all named holders;

          (b)  in cases where the signing person (as indicated on the Letter of
               Transmittal) is acting in a fiduciary or a representative
               capacity only when proper evidence of such person's authority so
               to act is submitted; and

          (c)  from persons other than the registered holder of Original Capital
               Securities provided that customary transfer requirements are
               fulfilled.

         You shall accept partial tenders of Original Capital Securities where
so indicated and as permitted in the Letter of Transmittal and deliver
certificates for Original Capital Securities to the transfer agent for division
and return any untendered Original Capital Securities to the holder (or such
other person as may be designated in the Letter of Transmittal) as promptly as
practicable after expiration or termination of the Exchange Offer.

         8.    Upon satisfaction or waiver of all of the conditions to the
Exchange Offer, the Trust will notify you (such notice, if given orally, to be
confirmed in writing) of its acceptance, promptly after the Expiration Date, of
all Original Capital Securities properly tendered and you, on behalf of the
Trust, will exchange such Original Capital Securities for Exchange Capital
Securities provided to you by or on behalf of the Trust and cause such Original
Capital Securities to be canceled. Delivery of Exchange Capital Securities will
be made on behalf of the Trust by you at the rate of $1,000



                                       3

liquidation amount of Exchange Capital Securities for each $1,000 liquidation
amount of the corresponding series of Original Capital Securities tendered
promptly after notice (such notice, if given orally, to be confirmed in writing)
of acceptance of said Original Capital Securities by the Trust; provided,
however, that in all cases, Original Capital Securities tendered pursuant to the
Exchange Offer will be exchanged only after timely receipt by you of
certificates for such Original Capital Securities (or confirmation of book-entry
transfer into your account at the Book-Entry Transfer Facility), a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) with
any required signature guarantees and any other required documents. The Trust
shall issue Exchange Capital Securities only in denominations of $1,000 or any
integral multiple thereof. Original Capital Securities may be tendered in whole
or in part in denominations of $100,000 and integral multiples of $1,000 in
excess thereof, provided that if any Original Capital Securities are tendered
for exchange in part, the untendered liquidation amount thereof must be $100,000
or any integral multiple of $1,000 in excess thereof.

         9.    Tenders pursuant to the Exchange Offer are irrevocable, except
that, subject to the terms and upon the conditions set forth in the Prospectus
and the Letter of Transmittal, Original Capital Securities tendered pursuant to
the Exchange Offer may be withdrawn at any time on or prior to the Expiration
Date.

         10.   The Trust shall not be required to exchange any Original Capital
Securities tendered if any of the conditions set forth in the Exchange Offer are
not met. Notice of any decision by the Trust not to exchange any Original
Capital Securities tendered shall be given orally (and confirmed in writing) by
the Trust to you.

         11.   If, pursuant to the Exchange Offer, the Trust does not accept for
exchange all or part of the Original Capital Securities tendered because of an
invalid tender, the occurrence of certain other events set forth in the
Prospectus under the caption "The Exchange Offer -- Conditions to the Exchange
Offer" or otherwise, you shall promptly after the expiration or termination of
the Exchange Offer return those certificates of Original Capital Securities not
accepted for exchange (or effect appropriate book-entry transfer), together with
any related required documents and the Letters of Transmittal relating thereto
that are in your possession, to the persons who deposited them.

         12.   All certificates for reissued Original Capital Securities,
unaccepted Original Capital Securities or Exchange Capital Securities shall be
forwarded (a) by first-class certified mail, return receipt requested, under a
blanket surety bond at the direction and expense of the Corporation protecting
you and the Trust from loss or liability arising out of the non-receipt or
non-delivery of such certificates; (b) by registered mail insured separately by
you at the expense of the Corporation, protecting you, the Corporation and the
Trust from loss or liability arising out of the non-receipt or non-delivery of
such certificates or (c) by effectuating appropriate book-entry transfer.

         13.   You are not authorized to pay or offer to pay any concessions,
commissions or solicitation fees to any broker, dealer, bank or other persons or
to engage or utilize any person to solicit tenders.

         14.   As Exchange Agent hereunder you:

               however, you determine to take any legal action hereunder, and,
               where the taking of such action might, in your judgment, subject
               or expose you to any expense or liability, you shall not be
               required to act unless you shall have been furnished with an
               indemnity satisfactory to you;

               or other instrument whatsoever not only as to its due execution

               Agent covered by this Agreement (or supplementing or qualifying
               any such actions) of officers of the Corporation;

          (g)  may consult with counsel satisfactory to you, including counsel
               for the Trust, with respect to any questions relating to your

               or opinion of such counsel, provided that you shall promptly
               notify the Corporation of any action taken or omitted by you in
               reliance upon such advice or opinion;

          (h)  are not authorized, and shall have no obligation, to pay any
               brokers, dealers or soliciting fees to any person; and

          (i)  shall not advise any person tendering Original Capital Securities
               pursuant to the Exchange Offer as to the wisdom of making such
               tender or as to the market value or decline or appreciation in
               market value of any Original Capital Securities.

         18.   You hereby expressly waive any lien, encumbrance or right of
set-off whatsoever that you may have with respect to funds deposited with you
for the payment of transfer taxes by reasons of amounts, if any, borrowed by the
Trust, or any of its subsidiaries or affiliates pursuant to any loan or credit
agreement with you or for compensation owed to you hereunder.

         19.   For services rendered as Exchange Agent hereunder, you shall be
entitled to the compensation set forth on Schedule I attached hereto, plus
reasonable out-of-pocket expenses and reasonable attorneys' fees, incurred in
connection with your services hereunder, within thirty days following receipt by
the Corporation of an itemized statement of such expenses and fees in reasonable
detail.

         20.(a)The Trust covenants and agrees to indemnify and hold you
               (which for purposes of this paragraph shall include your
               directors, officers and employees) harmless in your individual
               capacity and in your capacity as Exchange Agent hereunder from
               and against any and all loss, liability, cost, damage, expense
               and claim, including but not limited to reasonable attorneys'
               fees and expenses, incurred by you as a result of, arising out of
               or in connection with the performance by you of your duties under
               this Agreement or the compliance by you with the instructions set
               forth herein or delivered hereunder; provided, however, that the
               Trust shall not be liable for indemnification or otherwise, or
               hold you harmless, for any loss, liability, cost, damage, expense
               or claim arising out of your bad faith, gross negligence or
               willful misconduct. In no case shall the Trust be liable under
               this indemnity with respect to any claim against you unless the
               Trust shall be notified by you, by letter or by facsimile
               confirmed by letter, of the written assertion of a claim against
               you or of any other action commenced against you, promptly after
               you shall have received any such written assertion or notice of
               commencement of action. The Trust shall be entitled to
               participate at its own expense in the defense of any such claim
               or other action, and, if the Trust so elects, the Trust may
               assume the defense of any suit brought to enforce any such claim;
               provided, that the Trust shall not be entitled to assume the
               defense of any such action if the named parties to such action
               include both the Trust and you and representation of both parties
               by the same legal counsel would, in the written opinion of
               counsel to you, be inappropriate due to actual or potential
               conflicting interests between them. In the event that the Trust
               shall properly assume the defense of any such suit or threatened
               action in respect of which indemnification may be sought
               hereunder, the Trust shall not be liable for the fees and
               expenses of any counsel thereafter retained by you. The Trust
               shall not be liable under this paragraph for the fees and
               expenses of more than one legal counsel for you.

          (b)  You agree that, without the prior written consent of the Trust
               (which consent shall not be unreasonably withheld), you will not
               settle, compromise or consent to the entry of any pending or
               threatened claim, action, or proceeding in respect of which
               indemnification could be sought in accordance with the
               indemnification provisions of this Agreement (whether or not you
               or the Trust or any of its trustees or controlling persons is an
               actual or potential party to such claim, action or proceeding),
               unless

Wilmington Trust Company

               such settlement, compromise or consent includes an unconditional
               release of the Trust and its trustees and controlling persons
               from all liability arising out of such claim, action or
               proceeding.

         21.   The Trust understands that you are required in certain instances
to deduct 31% of the amounts to be paid with respect to interest paid on the
Exchange Capital Securities and proceeds from the sale, exchange, redemption or
retirement of the Exchange Capital Securities from holders who have not supplied
their correct Taxpayer Identification Number or required certification. You will
remit any such funds to the Internal Revenue Service in accordance with
applicable regulations.

         22.   You shall notify the Trust of the amount of any transfer taxes
that you have actual knowledge are payable in respect of the exchange of
Original Capital Securities.

         23.   This Agreement and your appointment as Exchange Agent hereunder
shall be construed and enforced in accordance with the laws of the State of
Delaware applicable to agreements made and to be performed entirely within such
state, and without regard to conflicts of law principles, and shall inure to the
benefit of, and the obligations created hereby shall be binding upon, the
successors and assigns of each of the parties hereto, and no other person shall
have any rights hereunder.

         24.   This Agreement may be executed in one or more counterparts, each
of which shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

         25.   In case any provision of this Agreement shall be invalid, illegal
or unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         26.   This Agreement shall not be deemed or construed to be modified,
amended, rescinded, canceled or waived, in whole or in part, except by a written
instrument signed by a duly authorized representative of the party to be
charged. This Agreement may not be modified orally.

         27.   Unless otherwise provided herein, all notices, requests and other
communications to any party hereunder shall be in writing (including facsimile
