(CONTINUED FROM PREVIOUS PAGE)
 
    State Street Bank and Trust Company is the Property Trustee (as defined
herein) of IUB Trust. IUB Trust exists for the purpose of issuing the Trust
Securities and investing the proceeds thereof in an equivalent amount of    %
Subordinated Debentures (the "Subordinated Debentures") of the Company. The
Subordinated Debentures will mature on December 31, 2027, which date may be (i)
shortened to a date not earlier than December 31, 2002, or (ii) extended to a
date not later than December 31, 2036, in each case if certain conditions are
met (including, in the case of shortening the Stated Maturity (as defined
herein), the Company having received prior approval of the Board of Governors of
the Federal Reserve System ("Federal Reserve") to do so if then required under
applicable capital guidelines or policies of the Federal Reserve). The Preferred
Securities will have a preference under certain circumstances with respect to
cash distributions and amounts payable on liquidation, redemption or otherwise
over the Common Securities. See "Description of the Preferred
Securities--Subordination of Common Securities."
 
    The holders of the Preferred Securities are entitled to receive preferential
cumulative cash distributions, at the annual rate of    % of the liquidation
amount of $10 per Preferred Security (the "Liquidation Amount"), accruing from
           , 1997, the date of original issuance, and payable quarterly in
arrears on the last day of March, June, September and December of each year,
commencing December 31, 1997 (the "Distributions"). The Company has the right,
so long as no Debenture Event of Default (as defined herein) has occurred and is
continuing, to defer payment of interest on the Subordinated Debentures at any
time or from time to time for a period not to exceed 20 consecutive quarters
with respect to each deferral period (each, an "Extension Period"); provided
that no Extension Period may extend beyond the Stated Maturity of the
Subordinated Debentures. Upon the termination of any such Extension Period and
the payment of all amounts then due, the Company may elect to begin a new
Extension Period subject to the requirements set forth herein. If interest
payments on the Subordinated Debentures are so deferred, Distributions on the
Preferred Securities will also be deferred, and the Company will not be
permitted, subject to certain exceptions described herein, to declare or pay any
cash distributions with respect to its capital stock or debt securities that
rank PARI PASSU with or junior to the Subordinated Debentures. WHILE THE COMPANY
INTENDS TO TAKE THE POSITION THAT THE SUBORDINATED DEBENTURES WILL NOT BE DEEMED
TO BE ISSUED WITH ORIGINAL ISSUE DISCOUNT ("OID"), INTEREST ON THE SUBORDINATED
DEBENTURES DURING AN EXTENSION PERIOD WILL CONTINUE TO ACCRUE (AND THE AMOUNT OF
DISTRIBUTIONS TO WHICH THE HOLDERS OF THE PREFERRED SECURITIES ARE ENTITLED WILL
ACCUMULATE) AT THE RATE OF    % PER ANNUM, COMPOUNDED QUARTERLY, AND THE HOLDERS
OF THE PREFERRED SECURITIES WILL BE REQUIRED TO INCLUDE INTEREST INCOME AS OID
IN THEIR GROSS INCOME FOR UNITED STATES FEDERAL INCOME TAX PURPOSES IN ADVANCE
OF RECEIPT OF THE CASH DISTRIBUTIONS WITH RESPECT TO SUCH DEFERRED INTEREST
PAYMENTS. A HOLDER OF PREFERRED SECURITIES THAT DISPOSES OF ITS PREFERRED
SECURITIES BETWEEN RECORD DATES FOR PAYMENTS OF DISTRIBUTIONS (AND CONSEQUENTLY
DOES NOT RECEIVE A DISTRIBUTION FROM IUB TRUST FOR THE PERIOD PRIOR TO SUCH
DISPOSITION) WILL NEVERTHELESS BE REQUIRED TO INCLUDE ACCRUED BUT UNPAID
INTEREST OR OID, IF ANY, ON THE SUBORDINATED DEBENTURES THROUGH THE DATE OF
DISPOSITION IN INCOME AS ORDINARY INCOME AND TO ADD THE AMOUNT OF ANY ACCRUED
OID TO ITS ADJUSTED TAX BASIS IN ITS PRO RATA SHARE OF THE UNDERLYING
SUBORDINATED DEBENTURES DEEMED DISPOSED OF. See "Description of the Subordinated
Debentures--Option to Extend Interest Payment Period," "Certain Federal Income
Tax Consequences--Potential Extension of Interest Payment Period and Original
Issue Discount" and "--Disposition of the Preferred Securities."
 
    The Company and IUB Trust believe that, taken together, the obligations of
the Company under the Guarantee, the Trust Agreement, the Subordinated
Debentures, the Indenture and the Expense Agreement (each as defined herein)
provide, in the aggregate, a full, irrevocable and unconditional guarantee, on a
subordinated basis, of all of the obligations of IUB Trust under the Preferred
Securities. See "Relationship Among the Preferred Securities, the Subordinated
Debentures and the Guarantee--Full and Unconditional Guarantee." The Guarantee
of the Company guarantees the payment of Distributions
 
                                                        (CONTINUED ON NEXT PAGE)
 
                                       2

(CONTINUED FROM PREVIOUS PAGE)
 
and payments on liquidation or redemption of the Preferred Securities, but only
in each case to the extent of funds held by IUB Trust, as described herein. See
"Description of the Guarantee--General." If the Company does not make interest
payments on the Subordinated Debentures held by IUB Trust, IUB Trust will have
insufficient funds to pay Distributions on the Preferred Securities. The
Guarantee does not cover payments of Distributions when IUB Trust does not have
sufficient funds to pay such Distributions. In such event, a holder of Preferred
Securities may institute a legal proceeding directly against the Company
pursuant to the terms of the Indenture to enforce payments of amounts equal to
such Distributions to such holder. See "Description of the Subordinated
Debentures--Enforcement of Certain Rights by Holders of the Preferred
Securities." The obligations of the Company under the Guarantee and the
Preferred Securities are subordinate and junior in right of payment to all
Senior Debt, Subordinated Debt and Additional Senior Obligations (each as
defined herein) of the Company. The Subordinated Debentures are unsecured
obligations of the Company and are subordinated to all Senior Debt, Subordinated
Debt and Additional Senior Obligations of the Company.
 
    The Preferred Securities are subject to mandatory redemption, in whole or in
part, upon repayment of the Subordinated Debentures at maturity or their earlier
redemption. Subject to Federal Reserve approval, if then required under
applicable capital guidelines or policies of the Federal Reserve, the
Subordinated Debentures are redeemable prior to maturity at the option of the
Company (i) on or after December 31, 2002, in whole at any time or in part from
time to time, or (ii) at any time, in whole (but not in part), within 180 days
following the occurrence of a Tax Event, a Capital Treatment Event or an
Investment Company Event (each as defined herein), in each case at a redemption
price equal to the accrued and unpaid interest on the Subordinated Debentures so
redeemed to the date fixed for redemption, plus 100% of the principal amount
thereof. See "Description of the Preferred Securities--Redemption."
 
    The Company has the right at any time to dissolve, wind-up or terminate IUB
Trust subject to the Company having received prior approval of the Federal
Reserve to do so if then required under applicable capital guidelines or
policies of the Federal Reserve. In the event of the voluntary or involuntary
dissolution, winding up or termination of IUB Trust, after satisfaction of
liabilities to creditors of IUB Trust as required by applicable law, the holders
of the Preferred Securities will be entitled to receive a Liquidation Amount of
$10 per Preferred Security, plus accumulated and unpaid Distributions thereon to
the date of payment, which may be in the form of a Subordinated Debenture having
an aggregate principal amount equal to the Liquidation Amount of such Preferred
Securities (and carrying with it accumulated interest in an amount equal to the
accumulated and unpaid Distributions then due on such Preferred Securities),
subject to certain exceptions. See "Description of the Preferred
Securities--Redemption" and "--Liquidation Distribution upon Termination."

                                  THE COMPANY
 
GENERAL
 
    Indiana United Bancorp (the "Company") is a bank and thrift holding company
headquartered in Greensburg, Indiana. Through its subsidiaries, Union Bank and
Trust Company of Indiana, a commercial bank organized under the laws of Indiana
("Union Bank"), and Regional Federal Savings Bank, a Federal savings bank
("Regional Bank"), the Company operates twelve offices in four eastern and
southern Indiana counties. (Union Bank and Regional Bank are sometimes
individually referred to herein as a "Bank" and collectively as the "Banks.")
Both subsidiaries offer a broad range of loan and deposit services to consumer,
agricultural and commercial customers. Union Bank also offers a full line of
personal and business trust services and property and casualty insurance
services. The principal executive office of the Company is located at 201 N.
Broadway, Greensburg, Indiana 47240 and its telephone number is (812) 663-0157.
 
    During the past five years the Company has focused on improving its net
interest margin by reducing its cost of funds and reallocating its assets.
Pursuit of this objective included divestiture of three Regional Bank branches
in 1994. Since 1993, total loans as a percentage of total assets have increased
from 57% to 70%, with the greatest percentage of growth concentrated in higher
yielding consumer loans. As a result, the Company's net interest margin since
1993 has increased from 3.52% to 4.13% per annum.

OPERATING PHILOSOPHY
 
    The Company operates in predominately rural and suburban markets and
embraces a community banking philosophy that emphasizes personal service and
convenience, community involvement, local decision-making authority, quick
responses to loan requests, and customized services.
 
    The Company endeavors to provide its branch managers, lending officers,
tellers and deposit service personnel with the authority to act promptly in
service of its customers within the scope of Company
 
                                       6
<PAGE>
policies. This highly responsive service attitude is enhanced by an efficient
corporate support staff and an investment in technology.
 
    The Company believes the benefits of this operating philosophy contribute to
its success while providing improved operating efficiencies, sound internal
controls and high credit underwriting standards.
 
BUSINESS STRATEGY
 
    The most fundamental and constant element of the Company's business strategy
has been to originate and maintain asset quality exceeding state and national
peer quality averages. The Company believes that maintaining high asset quality
is critical to creating long-term shareholder value and the Company has a
history of maintaining asset quality that has consistently placed it among peer
leaders.
 
    The Company holds either first or second market share positions as measured
by total deposits in two of the three markets it serves and intends to pursue
growth strategies that result in meaningful market share positions in other
rural or suburban communities. Such a strategy emphasizes growth by acquisition
over de novo expansion. The Company is seeking to identify potential
acquisitions in markets that offer opportunities to benefit from its community
banking philosophy and that will likely result in meaningful market share. In
conformity with this strategy, the Company has entered into an agreement to
acquire PTC, a bank holding company headquartered in Brookville, Indiana with
total assets of $300 million. PTC is also community focused, serving rural
communities with populations of 10,000 or less in markets contiguous to the
Company's existing locations. The transaction is regarded by both companies as a
merger of equals and will integrate management and directors of both
organizations. See "--Recent Developments."
 
    The Company also believes many larger banking companies operating in, or
contiguous to, Indiana will begin an accelerated program of branch divestitures.
The Company further believes many of these branch locations will be in
communities which are compatible with its growth strategies. In such event, the
Company intends to bid competitively in seeking to expand through branch
acquisitions.
 
OWNERSHIP
 
    As of November 1, 1997, the directors and executive officers of the Company
and their immediate families owned approximately 26% of the Company's stock.
Immediately after the PTC Merger, the directors and executive officers of the
Company and their immediate families are expected to own approximately 32% of
the Company's stock.
 
RECENT DEVELOPMENTS
 
    The Company is a party to an Agreement and Plan of Merger with PTC dated as
of October 8, 1997 (the "Merger Agreement") pursuant to which PTC would merge
with and into the Company, PTC's commercial bank subsidiary, People's Trust
Company, Brookville, Indiana, a commercial bank organized under the laws of
Indiana ("People's Trust"), would become a wholly owned subsidiary of the
Company, and each outstanding share of PTC at the effective time of the merger
would be converted into the right to receive 1.075 shares of common stock of the
Company (the "PTC Merger"). The Company expects to issue in the aggregate up to
1,136,417 shares of common stock in the PTC Merger. The PTC Merger is expected
to be completed in the first quarter of 1998.
 
    At September 30, 1997, PTC had total assets of $302.7 million, total
deposits of $275.7 million and total shareholders' equity of $23.7 million. PTC
had net income of $2.7 million for the nine months ended September 30, 1997,
compared to net income of $2.4 million for the nine months ended September 30,
1996. See "PTC Selected Financial Data" and "PTC Management's Discussion and
Analysis of Financial Condition and Results of Operations." People's Trust
engages in a general full-service commercial and
 
                                       7
<PAGE>
consumer banking business. People's Trust conducts its banking business through
17 offices located in the Indiana counties of Dearborn, Franklin, Jefferson,
Ripley, Rush, Fayette, Decatur, Switzerland and Wayne.
 
    PTC is subject to the informational reporting requirements of the Exchange
Act. Information about PTC may be obtained from the Public Reference Section of
the Commission or accessed through electronic means, including the Commission's
home page on the Internet (http://www.sec.gov), in the same manner that
information about the Company may be obtained. See "Available Information."
 
    The PTC Merger is expected to qualify as a "pooling of interests" for
accounting and financial reporting purposes. See "Summary of Pro Forma
Consolidated Financial Data," "Pro Forma Selected Financial Data" and "Index to
Consolidated Financial Statements and Pro Forma Consolidated Financial
Statements." The PTC Merger is intended to be a tax free reorganization so that
no gain or loss would be recognized by the Company or PTC, and no gain or loss
would be recognized by shareholders of PTC except in respect of cash received
for fractional shares or pursuant to the exercise of statutory dissenters'
rights. The PTC Merger is subject to various conditions, including requisite
shareholder and regulatory approvals. Accordingly, no assurance can be given
that the PTC Merger will be consummated. If the PTC Merger is not consummated,
the anticipated significant increase in the Company's capital base due to the
PTC Merger will not be realized. Consequently, due to regulatory capital
requirements, the Company's ability to utilize a portion of the offering
proceeds for future acquisitions and other growth would be adversely affected if
the PTC Merger is not consummated.
 
    Following the PTC Merger, pursuant to the Merger Agreement, the Board of
Directors of the Company will consist of ten members, five of which will have
been designated by the Company and five of which will have been designated by
PTC. The Merger Agreement also provides that the Company's Chairman of the
Board, President and Chief Executive Officer, Robert E. Hoptry, will continue to
be the Company's Chairman of the Board and Chief Executive Officer and that
PTC's President and Chief Executive Officer, James L. Saner, will be President
and Chief Operating Officer of the Company following the PTC Merger.
 
                                   IUB TRUST
 
    IUB Trust is a statutory business trust formed under Delaware law pursuant
to (i) a trust agreement, dated as of November 14, 1997, executed by the
Company, as depositor, and the trustees of IUB Trust (together with the Property
Trustee, the "Trustees"), and (ii) a certificate of trust filed with the
Secretary of State of the State of Delaware with an effective date of November
14, 1997. The initial trust agreement will be amended and restated in its
entirety (as so amended and restated, the "Trust Agreement") substantially in
the form filed as an exhibit to the Registration Statement of which this
Prospectus forms a part. The Trust Agreement will be qualified as an indenture
under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").
Upon issuance of the Preferred Securities, the purchasers thereof will own all
of the Preferred Securities. The Company will acquire all of the Common
Securities which will represent an aggregate liquidation amount equal to at
least 3% of the total capital of IUB Trust. The Common Securities will rank PARI
PASSU, and payments will be made thereon pro rata, with the Preferred
Securities, except that upon the occurrence and during the continuance of an
Event of Default (as defined herein) under the Trust Agreement resulting from a
Debenture Event of Default, the rights of the Company as holder of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption or otherwise will be subordinated to the rights of the holders of the
Preferred Securities. See "Description of the Preferred
Securities--Subordination of the Common Securities." IUB Trust exists for the
exclusive purposes of (i) issuing the Trust Securities representing undivided
beneficial interests in the assets of IUB Trust, (ii) investing the gross
proceeds of the Trust Securities in the Subordinated Debentures issued by the
Company, and (iii) engaging in only those other activities necessary, advisable,
or incidental thereto. The Subordinated Debentures and payments thereunder will
be the only assets of IUB Trust and payments under the Subordinated Debentures
will be the only revenue of IUB Trust. IUB Trust has a term of 55 years, but may
terminate earlier as provided in the Trust Agreement. The principal
 
                                       8
<PAGE>
executive office of IUB Trust is 201 North Broadway, Greensburg, Indiana 47240,
and its telephone number is (812) 663-0157.
 
    The number of Trustees will, pursuant to the Trust Agreement, initially be
five. Three of the Trustees (the "Administrative Trustees") will be persons who
are employees or officers of, or who are affiliated with, the Company. The
fourth trustee will be a financial institution that is unaffiliated with the
Company, which trustee will serve as institutional trustee under the Trust
Agreement and as indenture trustee for the purposes of compliance with the
provisions of the Trust Indenture Act (the "Property Trustee"). State Street
Bank and Trust Company, a state chartered trust company organized under the laws
of the Commonwealth of Massachusetts, will be the Property Trustee until removed
or replaced by the holder of the Common Securities. For purposes of compliance
with the provisions of the Trust Indenture Act, State Street Bank and Trust
Company will also act as trustee (the "Guarantee Trustee") under the Guarantee
and as Debenture Trustee (as defined herein) under the Indenture. The fifth
trustee will be an entity that maintains its principal place of business in the
State of Delaware (the "Delaware Trustee"). Wilmington Trust Company, a Delaware
chartered trust company, will act as Delaware Trustee.
 
    The Property Trustee will hold title to the Subordinated Debentures for the
benefit of the holders of the Trust Securities and in such capacity will have
the power to exercise all rights, powers and privileges under the Indenture. The
Property Trustee will also maintain exclusive control of a segregated non-
interest-bearing bank account (the "Property Account") to hold all payments made
in respect of the Subordinated Debentures for the benefit of the holders of the
Trust Securities. The Property Trustee will make payments of Distributions and
payments on liquidation, redemption and otherwise to the holders of the Trust
Securities out of funds from the Property Account. The Guarantee Trustee will
hold the Guarantee for the benefit of the holders of the Preferred Securities.
The Company, as the holder of all the Common Securities, will have the right to
appoint, remove or replace any Trustee and to increase or decrease the number of
Trustees. The Company will pay all fees and expenses related to IUB Trust and
the offering of the Trust Securities.
 
    The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights, are set forth in the Trust
Agreement, the Delaware Business Trust Act (the "Trust Act") and the Trust
Indenture Act. See "Description of the Preferred Securities."

                                      consist solely of the Subordinated Debentures and

                                      after the date of this Prospectus, to purchase up to

                                      initial offering price, solely to cover
                                      over-allotments, if any.
 
Distributions.......................  The Distributions payable on each Preferred Security
                                      will be fixed at a rate per annum of     % of the

                                      the date of original issuance of the Preferred
                                      Securities, and will be payable quarterly in arrears,
                                      on March 31, June 30, September 30 and December 31 of
                                      each year, commencing December 31, 1997. See

                                      Securities--Distributions--Payment of Distributions."
 
Option to Extend Interest Payment
  Period............................  The Company has the right, at any time, so long as no
                                      Debenture Event of Default has occurred and is
                                      continuing, to defer payments of interest on the
                                      Subordinated Debentures for a period not exceeding 20
                                      consecutive quarters; provided, that no Extension
                                      Period may extend beyond the Stated Maturity of the
                                      Subordinated Debentures. As a consequence of the
                                      extension by the Company of the interest payment
                                      period, quarterly Distributions on the Preferred
                                      Securities will be deferred (though such
                                      Distributions would continue to accrue with interest
                                      thereon compounded quarterly, since interest will
                                      continue to accrue and compound on the Subordinated
                                      Debentures) during any such Extension Period. During
                                      an Extension Period, the Company will be prohibited,
                                      subject to certain exceptions described herein, from
                                      declaring or paying any cash distributions with
                                      respect to its capital stock or debt securities that
                                      rank PARI PASSU with or junior to the Subordinated
                                      Debentures. Upon the termination of any Extension
                                      Period and the payment of all amounts then due, the
                                      Company may commence a new Extension Period, subject
                                      to the foregoing requirements. See "Description of
                                      the Preferred Securities-- Distributions--Extension
                                      Period" and "Description of the Subordinated

                                      Period." Should an Extension Period occur, the
                                      holders of Preferred Securities will be required to
                                      accrue interest income in their gross income for
                                      United States Federal income tax purposes in advance
                                      of receipt of the cash distributions with respect to
                                      such deferred interest payments.

Optional Redemption.................  The Preferred Securities are subject to mandatory
                                      redemption, in whole or in part, upon repayment of
                                      the Subordinated Debentures at maturity or their
                                      earlier redemption. Subject to Federal Reserve
                                      approval, if then required under applicable capital
                                      guidelines or policies of the Federal Reserve, the
                                      Subordinated Debentures are redeemable prior to

                                      or an Investment Company Event, in each case at the

                                      amount of the Subordinated Debentures, together with
                                      any accrued but unpaid interest to the date fixed for

                                      Debentures--Redemption or Exchange."
 
Distribution of Subordinated
  Debentures........................  The Company has the right at any time to terminate
                                      the Preferred Securities and cause the Subordinated
                                      Debentures to be distributed to the holders of the
                                      Preferred Securities in liquidation of IUB Trust,
                                      subject to the Company having received prior approval
                                      of the Federal Reserve to do so if then required
                                      under applicable capital guidelines or policies of
                                      the Federal Reserve. See "Description of the
                                      Preferred Securities--Redemption" and "--Liquidation
                                      Distribution upon Termination."
 
Guarantee...........................  The Company has guaranteed the payment of
                                      Distributions and payments on liquidation or
                                      redemption of the Preferred Securities, but only in
                                      each case to the extent of funds held by IUB Trust,
                                      as described herein. The Company and IUB Trust
                                      believe that, taken together, the obligations of the
                                      Company under the Guarantee, the Trust Agreement, the
                                      Subordinated Debentures, the Indenture and the
                                      Expense Agreement provide, in the aggregate, a full,
                                      irrevocable and unconditional guarantee, on a
                                      subordinated basis, of all of the obligations of IUB
                                      Trust under the Preferred Securities. The obligations
                                      of the Company under the Guarantee and the Preferred
                                      Securities are subordinate and junior in right of
                                      payment to all Senior Debt, Subordinated Debt and
                                      Additional Senior Obligations of the Company. If the
                                      Company does not make principal or interest payments
                                      on the Subordinated Debentures, IUB Trust will not
                                      have sufficient funds to make distributions on the
                                      Preferred Securities; in which event, the Guarantee
                                      will not apply to such Distributions until IUB Trust
                                      has sufficient funds available therefor. See
                                      "Description of the Guarantee."

Use of Proceeds.....................  The proceeds from the sale of the Preferred
                                      Securities offered hereby will be used by IUB Trust
                                      to purchase the Subordinated Debentures issued by the
                                      Company. The net proceeds to be received by the
                                      Company from the sale of the Subordinated Debentures
                                      to IUB Trust will be used for financing growth, which
                                      may include branch acquisitions, the establishment of
                                      de novo branches and/or acquisitions of other
                                      financial institutions, and for general corporate
                                      purposes. Pending any such use, the net proceeds will
                                      be invested in short-to-medium term investment grade
                                      financial instruments. See "Use of Proceeds."

    The following table sets forth certain unaudited pro forma condensed
combined financial data for the Company giving effect to the PTC Merger, which
will be accounted for as a pooling of interests, as if it had occurred as of the
beginning of the periods indicated herein, after giving effect to the pro forma
adjustments described in the notes to the Company and PTC Unaudited Pro Forma
Consolidated Financial Statements. This information should be read in
conjunction with the historical consolidated financial statements of the Company
and PTC, including the respective notes thereto, which are included elsewhere in
this Prospectus, and in conjunction with the consolidated historical financial

                                  RISK FACTORS
 
    PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER, TOGETHER WITH THE OTHER
INFORMATION CONTAINED AND INCORPORATED BY REFERENCE IN THIS PROSPECTUS, THE
FOLLOWING RISK FACTORS IN EVALUATING THE COMPANY AND ITS BUSINESS AND IUB TRUST
BEFORE PURCHASING THE PREFERRED SECURITIES OFFERED HEREBY. CERTAIN STATEMENTS IN
THIS SECTION CONSTITUTE "FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING OF
SECTION 27A OF THE SECURITIES ACT AND SECTION 21E OF THE EXCHANGE ACT. SUCH
FORWARD-LOOKING STATEMENTS INVOLVE KNOWN AND UNKNOWN RISKS, UNCERTAINTIES AND
OTHER FACTORS THAT MAY CAUSE ACTUAL RESULTS, PERFORMANCE OR ACHIEVEMENTS OF THE
COMPANY OR PTC TO DIFFER MATERIALLY FROM ANY FUTURE RESULTS, PERFORMANCE OR
ACHIEVEMENTS EXPRESSED OR IMPLIED BY SUCH FORWARD-LOOKING STATEMENTS.
 
RISK FACTORS RELATING TO THE PREFERRED SECURITIES
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE SUBORDINATED
  DEBENTURES
 
    The obligations of the Company under the Guarantee issued for the benefit of
the holders of Preferred Securities and under the Subordinated Debentures are
unsecured and rank subordinate and junior in right of payment to all Senior
Debt, Subordinated Debt and Additional Senior Obligations of the Company,
whether now existing or hereafter incurred. At September 30, 1997, the aggregate
outstanding Senior Debt, Subordinated Debt and Additional Senior Obligations of
the Company was approximately $4.6 million. Because the Company is a holding
company, the right of the Company to participate in any distribution of assets
of any Subsidiary Bank (as defined herein) upon such Subsidiary Bank's
liquidation or reorganization or otherwise (and thus the ability of the holders
of the Preferred Securities to benefit indirectly from such distribution) is
subject to the prior claims of creditors of that Subsidiary Bank, except to the
extent that the Company may itself be recognized as a creditor of that
Subsidiary Bank. The Subordinated Debentures, therefore, will be effectively
subordinated to all existing and future liabilities of the Subsidiary Banks and
the holders of the Subordinated Debentures and the Preferred Securities should
look only to the assets of the Company for payments on the Subordinated
Debentures. Neither the Indenture, the Guarantee nor the Trust Agreement places
any limitation on the amount of secured or unsecured debt, including Senior
Debt, Subordinated Debt and Additional Senior Obligations, that may be incurred
by the Company. See "Description of the Subordinated Debentures--Subordination"
and "Description of the Guarantee--Status of the Guarantee."
 
    The ability of IUB Trust to pay amounts due on the Preferred Securities is
dependent solely upon the Company making payments on the Subordinated Debentures
as and when required.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES; MARKET PRICE
  CONSEQUENCES
 
    The Company has the right under the Indenture, so long as no Debenture Event
of Default has occurred and is continuing, to defer the payment of interest on
the Subordinated Debentures at any time or from time to time for a period not
exceeding 20 consecutive quarters with respect to each Extension Period;
PROVIDED that no Extension Period may extend beyond the Stated Maturity of the
Subordinated Debentures. As a consequence of any such deferral, quarterly
Distributions on the Preferred Securities by IUB Trust will be deferred (and the
amount of Distributions to which holders of the Preferred Securities are
entitled will accumulate additional Distributions thereon at the rate of    %
per annum, compounded quarterly from the relevant payment date for such
Distributions) during any such Extension Period. During any such Extension
Period, the Company may 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 Company's capital stock, (ii) make any payment of principal, interest
or premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank PARI PASSU with or junior in interest to the Subordinated
Debentures or make any guarantee payments with respect to any guarantee by the
Company of the debt securities of any subsidiary of the Company if such
guarantee ranks PARI PASSU with or junior in interest to the Subordinated
Debentures (other than payments under the Guarantee), or (iii) redeem, purchase
or acquire less than all of the Subordinated Debentures or any of the Preferred
Securities. Prior to the
 
                                       15
<PAGE>
termination of any such Extension Period, the Company may further defer the
payment of interest; provided that no Extension Period may exceed 20 consecutive
quarters or extend beyond the Stated Maturity of the Subordinated Debentures.
Upon the termination of any Extension Period and the payment of all interest
then accrued and unpaid (together with interest thereon at the annual rate of
   % compounded quarterly, to the extent permitted by applicable law), the
Company may elect to begin a new Extension Period, subject to the above
requirements. Subject to the foregoing, there is no limitation on the number of
times that the Company may elect to begin an Extension Period. See "Description
of the Preferred Securities--Distributions--Extension Period" and "Description
of the Subordinated Debentures--Option to Extend Interest Payment Period."
 
    Should an Extension Period occur, each holder of Preferred Securities will
be required to accrue and recognize income (in the form of original issue
discount) in respect of its pro rata share of the interest accruing on the
Subordinated Debentures held by IUB Trust for United States Federal income tax
purposes. As a result, a holder of Preferred Securities must include such income
in gross income for United States Federal income tax purposes in advance of the
receipt of cash and will not receive the cash related to such income from IUB
Trust if the holder disposes of the Preferred Securities prior to the record
date for the payment of the related Distributions. See "Certain Federal Income
Tax Consequences-- Potential Extension of Interest Payment Period and Original
Issue Discount."
 
    The Company has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the
Subordinated Debentures. Should the Company elect, however, to exercise such
right in the future, the market price of the Preferred Securities is likely to
be adversely affected. A holder that disposes of its Preferred Securities during
an Extension Period, therefore, might not receive the same return on its
investment as a holder that continues to hold its Preferred Securities. In
addition, as a result of the existence of the Company's right to defer interest
payments, the market price of the Preferred Securities may be more volatile than
the market prices of other securities on which original issue discount accrues
that are not subject to such optional deferrals.
 
TAX EVENT, CAPITAL TREATMENT EVENT OR INVESTMENT COMPANY EVENT; REDEMPTION
 
    The Company has the right to redeem the Subordinated Debentures in whole
(but not in part) within 180 days following the occurrence of a Tax Event, a
Capital Treatment Event or an Investment Company Event (whether occurring before
or after December 31, 2002), and, therefore, cause a mandatory redemption of the
Preferred Securities. The exercise of such right is subject to the Company
having received prior approval of the Federal Reserve to do so if then required
under applicable capital guidelines or policies of the Federal Reserve.
 
    "Tax Event" means the receipt by IUB Trust of an opinion of counsel,
rendered by a law firm having a recognized tax and securities practice, to the
effect that, as a result of 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
as a result of any official administrative pronouncement or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or such pronouncement or decision is announced on or after the date of
issuance of the Preferred Securities under the Trust Agreement, there is more
than an insubstantial risk that (i) IUB 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 Subordinated Debentures, (ii)
interest payable by the Company on the Subordinated Debentures is not, or,
within 90 days of such opinion, will not be, deductible by the Company, in whole
or in part, for United States Federal income tax purposes, or (iii) IUB Trust
is, or will be within 90 days of the date of the opinion, subject to more than a
de minimis amount of other taxes, duties or other governmental charges. The
Company must request and receive an opinion with regard to such matters within a
reasonable period of time after it becomes aware of the possible occurrence of
any of the events described in clauses (i) through (iii) above.
 
                                       16
<PAGE>
    "Capital Treatment Event" means the receipt by IUB Trust of an opinion of
counsel, rendered by a law firm having a recognized banking law practice, to the
effect that, as a result of any amendment to or any change (including any
announced prospective change) in the laws (or any regulations thereunder) of the
United States or any political subdivision thereof or therein, or as a result of
any official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such proposed change, pronouncement or decision is announced on or after the
date of issuance of the Preferred Securities under the Trust Agreement, there is
more than an insubstantial risk of impairment of the Company's ability to treat
the aggregate Liquidation Amount of the Preferred Securities (or any substantial
portion thereof) as "Tier 1 capital" (or the then equivalent thereof) for
purposes of the capital adequacy guidelines of the Federal Reserve, as then in
effect and applicable to the Company, provided, however, that the inability of
the Company to treat all or any portion of the Liquidation Amount of the
Preferred Securities as Tier 1 capital shall not constitute the basis for a
Capital Treatment Event if such inability results from the Company having
cumulative preferred capital in excess of the amount which may qualify for
treatment as Tier 1 capital under applicable capital adequacy guidelines of the
Federal Reserve.
 
    "Investment Company Event" means the receipt by IUB Trust of an opinion of
counsel, rendered by a law firm having a recognized tax and securities law
practice, to the effect that, as a result of the occurrence of a change in law
or regulation or a change in interpretation or application of law or regulation
by any legislative body, court, governmental agency or regulatory authority, IUB
Trust is or will be considered an "investment company" that is required to be
registered under the Investment Company Act of 1940, as amended (the "Investment
Company Act"), which change becomes effective on or after the date of original
issuance of the Preferred Securities. See "--Possible Tax Law Changes" for a
discussion of certain legislative proposals that, if adopted, could give rise to
a Tax Event, which may permit the Company to cause a redemption of the Preferred
Securities prior to December 31, 2002.
 
SHORTENING OR EXTENSION OF STATED MATURITY OF THE SUBORDINATED DEBENTURES
 
    The Company has the right, at any time, to shorten the maturity of the
Subordinated Debentures to a date not earlier than December 31, 2002. The
exercise of such right is subject to the Company having received prior approval
of the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve. The Company also has the right to extend the
maturity of the Subordinated Debentures (whether or not IUB Trust is terminated
and the Subordinated Debentures are distributed to the holders of the Preferred
Securities) to a date no later than December 31, 2036, the 39th anniversary of
the initial issuance of the Preferred Securities. Such right may only be
exercised, however, if at the time such election is made and at the time of such
extension (i) the Company is not in bankruptcy, otherwise insolvent or in
liquidation, (ii) the Company is not in default in the payment of any interest
or principal on the Subordinated Debentures, (iii) IUB Trust is not in arrears
on payments of Distributions on the Preferred Securities and no deferred
Distributions are accumulated, and (iv) the Company has a Senior Debt rating of
investment grade. See "Description of the Subordinated Debentures--General."
 
RIGHTS UNDER THE GUARANTEE
 
    The Guarantee guarantees to the holders of the Preferred Securities, to the
extent not paid by IUB Trust, (i) any accrued and unpaid Distributions required
to be paid on the Preferred Securities, to the extent that IUB Trust has funds
available therefor at such time, (ii) the Redemption Price (as defined herein)
with respect to any Preferred Securities called for redemption, to the extent
that IUB Trust has funds available therefor at such time, and (iii) upon a
voluntary or involuntary dissolution, winding-up or liquidation of IUB Trust
(other than in connection with the distribution of Subordinated Debentures to
the holders of the Preferred Securities or a redemption of all of the Preferred
Securities), the lesser of (a) the amount of the Liquidation Distribution (as
defined herein), to the extent IUB Trust has funds available therefor at such
time, and (b) the amount of assets of IUB Trust remaining available for
distribution to the
 
                                       17
<PAGE>
holders of the Preferred Securities in liquidation of IUB Trust. The holders of
not less than a majority in Liquidation Amount of the Preferred 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 the Guarantee or to
direct the exercise of any trust power conferred upon the Guarantee Trustee
under the Guarantee. Any holder of Preferred Securities may institute a legal
proceeding directly against the Company to enforce its rights under the
Guarantee without first instituting a legal proceeding against IUB Trust, the
Guarantee Trustee or any other Person (as defined in the Guarantee). If the
Company were to default on its obligation to pay amounts payable under the
Subordinated Debentures, IUB Trust would lack funds for the payment of
Distributions or amounts payable on redemption of the Preferred Securities or
otherwise, and, in such event, the holders of the Preferred Securities would not
be able to rely upon the Guarantee for such amounts. In the event, however, that
a Debenture Event of Default has occurred and is continuing and such event is
attributable to the failure of the Company to pay interest on or principal of
the Subordinated Debentures on the payment date on which such payment is due and
payable, then a holder of Preferred Securities may institute a legal proceeding
directly against the Company for enforcement of payment to such holder of the
principal of or interest on such Subordinated Debentures having a principal
amount equal to the aggregate Liquidation Amount of the Preferred Securities of
such holder (a "Direct Action"). The exercise by the Company of its right, as
described herein, to defer the payment of interest on the Subordinated
Debentures does not constitute a Debenture Event of Default. In connection with
such Direct Action, the Company will have a right of set-off under the Indenture
to the extent of any payment made by the Company to such holder of Preferred
Securities in the Direct Action. Except as described herein, holders of
Preferred Securities will not be able to exercise directly any other remedy
available to the holders of the Subordinated Debentures or assert directly any
other rights in respect of the Subordinated Debentures. See "Description of the
Subordinated Debentures--Debenture Events of Default," "--Enforcement of Certain
Rights by Holders of Preferred Securities," and "Description of the Guarantee."
The Trust Agreement provides that each holder of the Preferred Securities by
acceptance thereof agrees to the provisions of the Guarantee and the Indenture.
 
NO VOTING RIGHTS EXCEPT IN LIMITED CIRCUMSTANCES
 
    Holders of Preferred Securities will have no voting rights except in limited
circumstances relating only to the modification of the Preferred Securities and
the exercise of the rights of IUB Trust as holder of the Subordinated Debentures
and the Guarantee. Holders of Preferred Securities will not be entitled to vote
to appoint, remove or replace the Property Trustee or the Delaware Trustee, as
such voting rights are vested exclusively in the holder of the Common Securities
(except upon the occurrence of certain events described herein). The Property
Trustee, the Administrative Trustees and the Company may amend the Trust
Agreement without the consent of holders of Preferred Securities to ensure that
IUB Trust will be classified for United States Federal income tax purposes as a
grantor trust even if such action adversely affects the interests of such
holders. See "Description of the Preferred Securities--Removal of IUB Trust
Trustees," and "--Voting Rights; Amendment of Trust Agreement."
 
POSSIBLE TAX LAW CHANGES
 
    Certain legislative proposals were made in 1996 and 1997 which were designed
to eliminate the ability of issuers of certain instruments to deduct interest
paid on those instruments. These proposals were not, however, incorporated into
the legislation recently enacted as the Taxpayer Relief Act of 1997.
Nevertheless, there can be no assurance that other legislation enacted after the
date hereof will not otherwise adversely affect the ability of the Company to
deduct the interest payable on the Subordinated Debentures, and such legislation
could be retroactive in effect. Consequently, there can be no assurance that a
Tax Event will not occur. A Tax Event would permit the Company, upon approval of
the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve, to cause a redemption of the Preferred
Securities before, as well as after, December 31, 2002. See "Description of the
Preferred Securities--Redemption--Tax Event Redemption, Capital Treatment Event
Redemption or Investment

Debentures--Redemption or Exchange" and "Certain Federal Income Tax
Consequences--Effect of Recent Changes in Tax Laws."
 
REDEMPTION; EXCHANGE OF PREFERRED SECURITIES FOR SUBORDINATED DEBENTURES
 
    The Company has the right at any time to dissolve, wind-up or terminate IUB
Trust and cause the Subordinated Debentures to be distributed to the holders of
the Preferred Securities in exchange therefor in liquidation of IUB Trust. The
exercise of such right is subject to the Company having received prior approval
of the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve. The Company will have the right, in certain
circumstances, to redeem the Subordinated Debentures in whole or in part, in
lieu of a distribution of the Subordinated Debentures by IUB Trust, in which
event IUB Trust will redeem the Trust Securities on a pro rata basis to the same
extent as the Subordinated Debentures are redeemed by the Company. Any such
distribution or redemption prior to the Stated Maturity will be subject to prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies of the Federal Reserve. See "Description of the Preferred
Securities-- Redemption--Tax Event Redemption, Capital Treatment Event
Redemption or Investment Company Event Redemption."
 
    Under current United States Federal income tax law, a distribution of
Subordinated Debentures upon the dissolution of IUB Trust would not be a taxable
event to the holders of the Preferred Securities. If, however, IUB Trust were to
be recharacterized as an association taxable as a corporation at the time of the
dissolution of IUB Trust, the distribution of the Subordinated Debentures would
likely constitute a taxable event to IUB Trust and the holders of the Preferred
Securities. Moreover, a dissolution of IUB Trust in which holders of the
Preferred Securities receive cash will be a taxable event to such holders. See
"Certain Federal Income Tax Consequences--Receipt of Subordinated Debentures or
Cash Upon Liquidation of IUB Trust."
 
    There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Debentures that may be distributed in exchange
for Preferred Securities upon a dissolution or liquidation of IUB Trust. The
Preferred Securities or the Subordinated Debentures, may trade at a discount to
the price that the investor paid to purchase the Preferred Securities offered
hereby. Because holders of Preferred Securities may receive Subordinated
Debentures, prospective purchasers of Preferred Securities are also making an
investment decision with regard to the Subordinated Debentures and should
carefully review all the information regarding the Subordinated Debentures
contained herein.
 
    If the Subordinated Debentures are distributed to the holders of the
Preferred Securities upon the liquidation of IUB Trust, the Company will use its
best efforts to list the Subordinated Debentures on the Nasdaq National Market
or such stock exchanges, if any, on which the Preferred Securities are then
listed.
 
TRADING PRICE; ABSENCE OF PRIOR PUBLIC MARKET FOR THE PREFERRED SECURITIES
 
    The Preferred Securities may trade at prices that do not fully reflect the
value of accrued but unpaid interest with respect to the underlying Subordinated
Debentures. A holder of Preferred Securities that disposes of its Preferred
Securities between record dates for payments of Distributions (and consequently
does not receive a Distribution from IUB Trust for the period prior to such
disposition) will nevertheless be required to include accrued but unpaid
interest on the Subordinated Debentures through the date of disposition in
income as ordinary income and to add such amount to its adjusted tax basis in
its pro rata share of the underlying Subordinated Debentures deemed disposed of.
Such holder will recognize a capital loss to the extent the selling price (which
may not fully reflect the value of accrued but unpaid interest) is less than its
adjusted tax basis (which will include all accrued but unpaid interest). Subject
to certain limited exceptions, capital losses cannot be applied to offset
ordinary income for United States Federal income tax purposes. See "Certain
Federal Income Tax Consequences--Disposition of Preferred Securities."
 
                                       19
<PAGE>
    There is no current public market for the Preferred Securities. Although
application has been made to approve the Preferred Securities for quotation on
the Nasdaq National Market, there can be no assurance that an active public
market will develop for the Preferred Securities or that, if such market
develops, the market price will equal or exceed the public offering price set
forth on the cover page of this Prospectus. The public offering price for the
Preferred Securities has been determined through negotiations between the
Company and the Underwriter (as defined herein). Prices for the Preferred
Securities will be determined in the marketplace and may be influenced by many
factors, including prevailing interest rates, the liquidity of the market for
the Preferred Securities, investor perceptions of the Company and general
industry and economic conditions.
 
PREFERRED SECURITIES ARE NOT INSURED
 
    The Preferred Securities are not insured by the Bank Insurance Fund (the
"BIF") or the Savings Association Insurance Fund (the "SAIF") of the Federal
Deposit Insurance Corporation (the "FDIC") or by any other governmental agency.
 
RISK FACTORS RELATING TO THE COMPANY
 
NO ASSURANCE OF PTC MERGER
 
    The PTC Merger is subject to various conditions, including requisite
shareholder and regulatory approvals. Accordingly, no assurance can be given
that the PTC Merger will be consummated. If the PTC Merger is not consummated,
the anticipated significant increase in the Company's capital base due to the
PTC Merger will not be realized. Consequently, due to regulatory capital
requirements, the Company's ability to utilize a portion of the offering
proceeds for future acquisitions and other growth would be adversely affected if
the PTC Merger is not consummated.
 
NO ASSURANCE OF SUCCESSFUL INTEGRATION OF PTC
 
    Based on September 30, 1997 financial information, the PTC Merger would
increase the assets of the Company by approximately 89% to $645 million. See
"Business of the Company--Recent Developments." The Company's ability to
integrate the business and operations of PTC into its operations following the
PTC Merger without adversely affecting the level of profitability of the Company
cannot be assured.
 
STATUS OF THE COMPANY AS A BANK HOLDING COMPANY
 
    The Company is a legal entity separate and distinct from the Banks, although
the principal source of the Company's cash revenues is dividends from the Banks.
The ability of the Company to pay the interest on, and principal of, the
Subordinated Debentures will be significantly dependent on the ability of the
Banks to pay dividends to the Company and the ability of the Company to realize
a return on its investments in amounts sufficient to service the Company's debt
obligations. Payment of dividends by the Banks is restricted by various legal
and regulatory limitations.
 
    The right of the Company to participate in the assets of any subsidiary upon
the latter's liquidation, reorganization or otherwise (and thus the ability of
the holders of Preferred Securities to benefit indirectly from any such
distribution) will be subject to the claims of the subsidiaries' creditors,
which will take priority except to the extent that the Company may itself be a
creditor with a recognized claim. As of September 30, 1997, the Company had
indebtedness of $4.6 million at the Company level and, through its subsidiaries,
indebtedness and other liabilities of approximately $307.3 million.
 
    The Banks are also subject to restrictions under Federal law that limit the
transfer of funds by them to the Company, whether in the form of loans,
extensions of credit, investments, asset purchases or otherwise. Such transfers
by the Banks to the Company or any nonbank subsidiary of the Company are limited
in amount to 10% of such Bank's capital and surplus and, with respect to the
Company and all its nonbank subsidiaries, to an aggregate of 20% of such Bank's
capital and surplus. Furthermore, such loans and
 
                                       20
<PAGE>
extensions of credit are required to be secured in specified amounts. Federal
law also prohibits the Banks from purchasing "low-quality" assets from
affiliates.
 
GROWTH STRATEGY
 
    The Company intends to pursue a growth strategy that includes acquisitions
of commercial banks in non-urban areas. There are risks associated with the
Company's acquisition strategy that could adversely affect net income. These
risks include, among others, inaccurately assessing the asset quality of a
particular institution or branch being acquired, encountering greater than
anticipated costs of incorporating acquired businesses or branches into the
Company, and being unable to deploy profitably funds acquired in an acquisition.
There can be no assurances that the Company will be successful in implementing,
or will have the necessary regulatory capital or acquisition opportunities to
implement, its growth strategy. Moreover, the Company anticipates that it will
be in substantial competition with other financial institutions for potential
acquisition candidates and branches.
 
ADEQUACY OF ALLOWANCE FOR LOAN LOSSES
 
    The risk of loan losses varies with, among other things, general economic
conditions, the type of loan being made, the creditworthiness of the borrower
over the term of the loan and, in the case of a collateralized loan, the value
of the collateral for the loan. Management maintains an allowance for loan
losses based upon, among other things, historical experience, an evaluation of
economic conditions and regular review of delinquencies and loan portfolio
quality. Based upon such factors, management makes various assumptions and
judgments about the ultimate collectibility of the loan portfolio and provides
an allowance for loan losses based upon a percentage of the aggregate balance of
outstanding loans and specific loans for which ultimate collectibility is
considered questionable. If management's assumptions and judgments prove to be
incorrect and the allowance for loan losses is inadequate to absorb future
credit losses, or if the bank regulatory authorities require any Bank to
increase the allowance for loan losses, such Bank's earnings (and consequently
the Company's earnings) could be significantly and adversely affected. Because
certain lending activities involve greater risks, the percentage applied to
specific loan types may vary.
 
    The Company actively manages its nonperforming loans in an effort to
minimize credit losses and monitors its asset quality to maintain an adequate
allowance for loan losses. Although management believes that its allowance for
loan allowances is adequate, there can be no assurance that the allowance will
prove sufficient to cover future credit losses. Further, although management
uses the best information available to make determinations with respect to the
allowance for loan losses, future adjustments may be necessary if economic
conditions differ substantially from the assumptions used or if adverse
developments arise with respect to the Company's nonperforming or performing
loans. Material additions to the Company's allowance for loan losses would
result in a decrease in the Company's net income, possibly its capital, and
could result in the inability to pay dividends, among other adverse
consequences.
 
EFFECT OF INTEREST RATE FLUCTUATIONS AND ECONOMIC CONDITIONS
 
    The Company's consolidated results of operations depend to a large extent on
the level of its net interest income, which is the difference between interest
income from interest-earning assets (such as loans and investments) and interest
expense on interest-bearing liabilities (such as deposits and borrowings). If
interest-rate fluctuations cause its cost of funds to increase faster than the
yield on its interest-earning assets, net interest income will be reduced. The
Company measures its interest-rate risks monthly using static gap analyses. The
differences between an institution's interest-rate sensitive assets and its
interest-rate sensitive liabilities at a point in time is its gap position. A
negative gap indicates that cumulative interest-rate sensitive liabilities
exceed cumulative interest-rate sensitive assets for that period. A positive gap
indicates that cumulative interest-rate assets exceed interest-rate sensitive
liabilities for that period.
 
    Fluctuations in interest rates are not predictable or controllable. The
Company endeavors to structure its asset and liability management strategies to
mitigate the impact on net interest income of changes in
 
                                       21
<PAGE>
market interest rates. However, there can be no assurance that the Company will
be able to manage interest rate risk so as to avoid significant adverse effects
in net interest income. At September 30, 1997, the Company had a one year
cumulative negative gap of 8.9%. This negative one year gap position may have a
negative impact on earnings in an increasing interest rate environment. While
the Company uses various monitors of interest-rate risk, it is unable to predict
future fluctuations in interest rates or the specific impact thereof.
 
COMPETITION
 
    Banking institutions operate in a highly competitive environment. The
Company and the Banks compete with other bank or thrift holding companies,
commercial banks, credit unions, savings institutions, finance companies,
mortgage companies, mutual funds, and other financial institutions, many of
which have substantially greater financial resources than the Company. Certain
of these competitors offer products and services that are not offered by the
Company and certain competitors are not subject to the same extensive laws and
regulations as the Company. Federal and state legislation and/or regulations
also affect the Company's competitiveness in the financial services business. It
is impossible to predict the competitive impact on the Company of certain
Federal and state legislation and/or regulations relating to the banking
industry and interstate banking.
 
ECONOMIC CONDITIONS AND MONETARY POLICY
 
    The operating results of the Company will depend to a great extent upon the
rate differentials that result from the difference between the income it
receives from its loans, securities and other interest-earning assets and the
interest expense it pays on its deposits and other interest-bearing liabilities.
These rate differentials are highly sensitive to many factors beyond the control
of the Company, including general economic conditions and the policies of
various governmental and regulatory authorities, in particular the Federal
Reserve.
 
    Like other depository institutions, the Company is affected by the monetary
policies implemented by the Federal Reserve. A primary instrument of monetary
policy employed by the Federal Reserve is the restriction of the expansion of
the money supply through open market operations, including the purchase and sale
of government securities and the adjustment of reserve requirements. These
actions may at times result in significant fluctuations in interest rates, which
could have adverse effects on the operations of the Company. In particular, the
Company's ability to make loans and attract deposits, as well as public demand
for loans, could be adversely affected.
 
LOCAL ECONOMIC CONDITIONS
 
    The success of the Company is dependent to a certain extent upon the general
economic conditions in the geographic markets served by the Banks. Although the
Company expects that economic conditions will be favorable in these markets, no
assurance can be given that favorable economic conditions will prevail. Adverse
changes in economic conditions in the geographic markets that the Banks serve
could result in lower lending activity, impair the Bank's ability to collect
existing loans, or otherwise have a negative effect on the operating results and
financial condition of the Company.
 
GOVERNMENT REGULATION
 
    The Company and the Banks each are subject to extensive state and Federal
governmental supervision, regulation and control. Future legislation and
government policy could adversely affect the banking industry and the operations
of the Company and the Bank. See "Business of the Company -- Regulation and
Supervision of the Company," "-- Regulation and Supervision of the Subsidiary
Banks" and "--Legislation."
 
                                       22
<PAGE>
                                USE OF PROCEEDS
 
    IUB Trust will use the gross proceeds received from the sale of the
Preferred Securities to purchase Subordinated Debentures from the Company. The
Company will receive approximately $17.5 million ($20.1 million if the
Underwriter's over-allotment option is exercised in full) from the sale of the
Subordinated Debentures to IUB Trust. Approximately $9.8 million, or 53% of the
aggregate amount of the Preferred Securities offered hereby, are expected to
qualify as Tier 1 capital or core capital with respect to the Company under the
risk-based capital guidelines established by the Federal Reserve. Under such
guidelines, capital received from the proceeds of the sale of the Preferred
Securities cannot constitute more than 25% of the total Tier 1 capital of the
Company (the "25% Capital Limitation"). Consequently the amount of Preferred
Securities in excess of the 25% Capital Limitation (approximately $8.7 million
or 47% of the aggregate amount of the Preferred Securities) will constitute Tier
2 capital, or supplementary capital, of the Company. Subsequent to the PTC
Merger, approximately $17.1 million, or 92% of the aggregate amount of the
Preferred Securities, are expected to qualify as Tier 1 capital and $1.4
million, or 8 % of the aggregate amount of the Preferred Securities, will
constitute Tier 2 capital. The net proceeds to be received by the Company from
the sale of the Subordinated Debentures will be used for financing growth, which
may include branch acquisitions, the establishment of de novo branches and/or
acquisitions of other financial institutions. Other than the PTC Merger, the
Company does not have any specific plans, arrangements, agreements or
understandings with any other person for any acquisitions at the current time.
In addition, a portion of the proceeds may be used for general corporate
purposes, including investments in or advances to Union Bank and/or Regional
Bank and/or, following the completion of the PTC Merger, People's Trust. Pending
any such use, the net proceeds may be invested in short-to-medium-term
obligations. The precise amounts and timing of the application of proceeds will
depend upon the funding requirements of the Company and its subsidiaries and the
availability of other funds.
 
                      MARKET FOR THE PREFERRED SECURITIES
 
    Application has been made to have the Preferred Securities approved for
quotation on the Nasdaq National Market under the symbol "IUBCP." Although the
Underwriter has informed the Company that it presently intends to make a market
in the Preferred Securities, there can be no assurance that an active and liquid
trading market will develop or, if developed, that such a market will continue.
The offering price and distribution rate have been determined by negotiations
among representatives of the Company and the Underwriter, and the offering price
of the Preferred Securities may not be indicative of the market price following
the offering. See "Underwriting."
 
                              ACCOUNTING TREATMENT
 
    IUB Trust will be treated, for financial reporting purposes, as a subsidiary
of the Company and, accordingly, the accounts of IUB Trust will be included in
the consolidated financial statements of the Company. The Preferred Securities
will be presented as a separate category of long-term debt in the consolidated
balance sheet of the Company under the caption "Guaranteed preferred beneficial
interests in the Company's Subordinated Debentures," and appropriate disclosures
about the Preferred Securities, the Guarantee and the Subordinated Debentures
will be included in the notes to consolidated financial statements. The Company
will record Distributions payable on the Preferred Securities as interest
expense in its consolidated statements of income for financial reporting
purposes.
 
    All future reports of the Company filed under the Exchange Act while the
Preferred Securities are outstanding will (a) present the Trust Securities
issued by IUB Trust on the balance sheet as a separate category of long-term
debt item entitled "Guaranteed preferred beneficial interests in the Company's
Subordinated Debentures," (b) include in a footnote to the financial statements
disclosure that the sole assets of IUB Trust are the Subordinated Debentures
(including the outstanding principal amount, interest rate and maturity date of
such Subordinated Debentures), and (c) include in a footnote to the financial
statements disclosure that the Company owns all of the Common Securities of IUB
Trust, the sole assets of IUB Trust are the Subordinated Debentures, and the
back-up obligations, in the aggregate, constitute a full and unconditional
guarantee by the Company of the obligations of IUB Trust under the Preferred
Securities.

(1) In connection with the issuance of the preferred beneficial interest in the
    Company's Subordinated Debentures, the Company estimates it will incur
    expenses of $1,040,000 (including Underwriter's compensation of $740,000).
    The Subordinated Debentures will mature on December 31, 2027, which date may
    be, if certain conditions are met, (a) shortened to a date not earlier than
    December 31, 2002, or (b) extended to a date not later than December 31,
    2036.
 
(2) The leverage ratio is Tier 1 capital divided by adjusted total assets after
    deducting intangible assets.
 
(3) The capital ratios, as adjusted, are computed including the total estimated
    proceeds from the sale of the Preferred Securities, in a manner consistent
    with Federal Reserve guidelines.
 
(4) Federal Reserve guidelines for calculation of Tier 1 capital to
    risk-weighted assets limit the amount of cumulative preferred stock which
    can be included in Tier 1 capital to 25% of total Tier 1 capital.
    Approximately $9.8 million (or $17.1 million following the PTC Merger) of
    the aggregate amount of the Preferred Securities offered hereby will be
    included as Tier 1 capital for the Company.

to the same quarter of 1996. Earnings for the first nine months of 1997
increased 59% to $2,868,000 compared to the same period in 1996.
 
    Legislation enacted on September 30, 1996 together with companion
legislation enacted earlier in the quarter resulted in a $474,000 reduction in
1996 net income for the three-month and nine-month periods ended September 30,
1996. The legislation required a special assessment on thrift institutions,
based on March 1995 deposit levels, in order to recapitalize the SAIF, resulting
in a pre-tax charge of $545,000. Additionally, a tax advantage available to
thrift institutions in the calculation of allowable tax bad debt reserves was
eliminated, granting forgiveness of any tax liability prior to 1987, but
resulting in an income tax expense of $145,000 on the bad debt reserve recapture
since January 1, 1987.
 
    Before the nonrecurring charges, net income for the first nine months of
1996 would have been $2,273,000 and earnings for the third quarter would have
been $792,000. Compared with adjusted 1996 income, earnings for the third
quarter of 1997 increased 14% and year-to-date earnings increased 26%.
 
    Non-interest income in 1997 reflects approximately $179,000 of nonrecurring
income from the sale of other real estate owned. Insurance commissions in 1997
declined due mainly to lower levels of profit sharing income based on claims
experience. Trust income and service charge income for 1997 increased over the
prior year period. Non-interest expense reflects increased salaries and employee
benefits and reduced FDIC assessments (excluding the special 1996 assessment)
due to a lower insurance assessment rate.
 
    Net income per common share for the third quarter equaled $0.72 in 1997,
compared to $0.25 in 1996. Per share earnings for the first nine months of 1997
and 1996 were $2.29 and $1.40 respectively. Net income for 1996 was reduced by
$0.38 per common share due to the nonrecurring charges for the special SAIF
assessment and expense related to the tax law change. Excluding the nonrecurring
charges, net income per common share for the third quarter of 1996 would have
equaled $0.63 and nine-month net income per common share would have equaled
$1.78.
 
    The Company's return on average total assets for the third quarter was 1.06%
in 1997, and 0.40% in 1996. Year-to-date return on average total assets was
1.14% and 0.77% for 1997 and 1996. Before the nonrecurring charges, return on
average assets in 1996 would have been 0.99% for the third quarter and 0.97%
year-to-date.
 
    Return on average common shareholders' equity for the third quarter was
12.17% in 1997 and 4.66% in 1996. Year-to-date return on average shareholders'
equity was 13.39% and 8.82% for 1997 and 1996, respectively. Without the
nonrecurring charges, return on average common shareholders' equity in 1996
would have been 11.69% for the third quarter and 11.21% year-to-date.
 
NET INTEREST INCOME
 
    The volume and yield of earning assets and the cost of interest-bearing
liabilities influence net interest income. Net interest margin reflects the mix
of interest-bearing and non-interest-bearing liabilities that fund earning
assets, as well as interest spreads between the rates earned on these assets and
the rates paid
 
                                       28
<PAGE>
on interest-bearing liabilities. Third quarter net interest income of $3,312,000
in 1997 increased 10% from $3,002,000 in 1996. The first nine months of net
interest income increased by $935,000 or 11% over the same period in 1996.
 
    Throughout 1996 and the current year, the Company has employed a
deposit-pricing strategy focused on retaining and attracting lower cost
short-to-medium term funds. Management correctly anticipated a relatively flat
rate environment throughout 1996 and thus far into 1997. The Company believes
this strategy greatly enhanced 1996 net interest income and has had a positive
effect on the first nine months of 1997 earnings, even though interest rates
have increased slightly since year-end 1996. In the first nine months of 1997,
the Company increased its net interest margin to 4.13% or 15 basis points over
the same period last year.
 
PROVISION FOR LOAN LOSSES
 
    This topic is discussed under the heading "--Loans, Credit Risk and the
Allowance and Provision for Possible Loan Losses".
 
NON-INTEREST INCOME
 
    Non-interest income in the first nine months of 1997 exceeded the prior year
period by $277,000 or 25%. Nonrecurring non-interest income of $179,000 was
realized on the sale of real estate acquired in 1996 in lieu of foreclosure. Net
security losses of $80,000 were realized in the first nine months of 1997
compared to no gain or loss for the same period in 1996. Third quarter
non-interest income declined from the same period last year by $16,000 primarily
as a result of securities losses of $83,000 during the third quarter of 1997.
 
    Service charges on deposit accounts represent the largest component of the
first nine months of 1997 recurring non-interest income, equaling 32% in 1997
and 35% in 1996. Service charges on deposit accounts in the first nine months of
1997 increased by $84,000, or 22%, primarily due to the strong growth in a new
interest-bearing checking account introduced in early 1996. Deposit growth,
interest rate variables and non-sufficient funds charges have also affected
service charge income in 1997. Management believes that throughout the remainder
of 1997 the Company will experience additional deposit growth, generating even
higher service charge income. Insurance commissions declined $27,000 in the
first nine months of 1997 compared to the same period last year. This decline
represents the loss of year-end profit sharing programs from primary carriers
due to poor claims experience and to a lower volume of business. Trust income
increased $19,000 over 1996 due to an increase in estate income and assets under
management. The level of estate assets administered may cause trust income to
fluctuate significantly from year to year.

NON-INTEREST EXPENSE
 
    The largest component of non-interest expense is personnel expense.
Personnel expenses increased in the first nine months of 1997 by $105,000, or
3%. Improvements in technology implemented in the past 21 months have enabled
the Company to effectively control staffing levels during the periods presented.
Normal staff salary adjustments and increased benefit costs have been incurred
in both 1997 and 1996. Both periods include amounts accrued in connection with
the employee performance incentive compensation plan. Personnel expenses for the
full year in 1997 are not expected to change materially from 1996.
 
    The 1997 omnibus-spending package enacted on September 30, 1996 required the
thrift industry to recapitalize SAIF with a one-time assessment, based on March
31, 1995 deposits, and delayed a pro rata sharing of the Financing Corp.
("FICO") bond interest payments for three years. The one-time assessment imposed
on Regional Bank equaled approximately $545,000 and reduced 1996 third quarter
earnings.
 
    Deposit insurance premiums (excluding the $545,000 special assessment in
1996) were $87,000 less in 1997 compared to the same prior year period due to an
overall lower rate on which the insurance premium was calculated. Since the bank
insurance fund reached a mandated funding level in 1995, the 1996 assessment
rate for the Company's commercial bank was reduced to the $2,000 per year
minimum level permissible increasing to 1.29 cents per $100 of deposits in 1997.
 
    Through the year 1999, thrift institutions will pay approximately five times
higher assessment rates than commercial banks (6.44 cents versus 1.29 cents per
$100 of deposits), but this is a significant reduction from the 23 cents per
$100 of deposits assessed prior to September 30, 1996. Commencing in the year
2000, commercial banks and thrifts will pay the same assessment rate of 2.43
cents per $100 of deposits. Based on current deposit levels and projected
growth, Regional Bank will save approximately $540,000 in the three-year period
through 1999 due to the lower assessment rate.

INCOME TAXES
 
    In August 1996, President Clinton signed into law the Small Business Job
Protection Act of 1996. Included within that tax legislation was the repeal of
certain bad debt provisions applicable to thrifts. The percent-of-taxable-income
method for computing additions to the thrift tax bad debt reserves for years
beginning after December 31, 1995 was eliminated. The bill also required that
thrift institutions recapture all or a portion of their tax bad debt reserves
added since December 31, 1987. Accordingly, the Company recorded a $145,000
income tax expense in the third quarter of 1996 related to the tax bad debt
reserve recapture for Regional Bank. The unrecaptured base year reserve at
December 31, 1987 will not be subject to recapture as long as the institution
continues to carry on the business of banking.
 
                                       30
<PAGE>
    The effective tax rate (excluding the aforementioned bad debt reserve
recapture) for the first nine months was approximately 40% for both 1997 and
1996. The Company and its subsidiaries will file consolidated income tax returns
for 1997.
 
FINANCIAL CONDITION
 
    Total assets at September 30, 1997 increased $13,705,000 to $342,051,000
from $328,346,000 at December 31, 1996.
 
    Total average loans for the first nine months of 1997 have increased
$27,210,000 or 13% and average instalment loans have increased $14,569,000 or
70% compared to the same period in 1996. Average loans represent approximately
69% of average assets in the first nine months of 1997 compared to 66% for the
same period in 1996. Management intends to continue to emphasize loan growth
throughout the remainder of 1997. Securities maturities and increased deposits
have been used to fund loan growth in 1997.
 
    Average earning assets represented 95% of average total assets for the first
nine months of 1997 and 1996.
 
    Average non-interest-bearing deposits for the first nine months of 1997
increased 7% compared to the same period in 1996. Average interest-bearing
deposits increased $19,721,000 or 8% for the 1997 period compared to 1996.
Average interest-bearing demand deposits increased $10,098,000 for the nine
months in 1997 compared to 1996, primarily due to the success of a new
interest-bearing checking account introduced early in 1996. Average savings
accounts have decreased slightly for the 1997 period compared to 1996. Average
money market investment accounts decreased $5,437,000 or 15% compared to the
prior year due to the shifting of funds to the new interest-bearing demand
deposit. Average certificates of deposit and other time deposits increased
approximately $15,501,000 for the nine months in 1997 compared to the prior year
period.
 
    Long-term debt is primarily the balance of the Company's loan for the
purchase of Regional Bank. A principal payment of $375,000 was paid on June 30,
1997. During the third quarter of 1997, the Company negotiated the refinancing
of the balance of its outstanding debt of $4,625,000, which was originally due
December 31, 1997. The new note will mature on July 1, 2002 and requires a
principal payment of $125,000 on January 1, 1998 and $500,000 semiannual
payments thereafter on July 1 and January 1 until maturity. Interest will be
paid quarterly. The loan shall bear interest at a rate equal to the lender's
prime rate, less 25 basis points and at the Company's option, all or any portion
of the outstanding balance may bear interest at a fixed rate equal to 150 basis
points above LIBOR for one, two, three, six or twelve month interest periods.
The loan is secured by the capital stock of the Company's subsidiaries and the
loan agreement contains restrictions on debt, guarantees and mergers, in
addition to other affirmative and negative covenants. The Company believes it
has complied with all terms and covenants of the loan agreement.
 
    Shareholders' equity was $30,084,000 on September 30, 1997 compared to
$27,749,000 at year-end 1996. Book value per common share increased to $24.05 or
8% from $22.18 at December 31, 1996. The unrealized gain on securities available
for sale, net of taxes, totaled $487,000 or $0.39 per share at September 30,
1997 compared to an unrealized gain of $95,000 or $0.07 at year end 1996.
Excluding the net unrealized gains on securities available for sale, book value
per share was $23.66 at September 30, 1997 or an increase of 7% over the
comparable book value at year end 1996. The Company redeemed $1,000,000 of its
preferred stock in March 1996, $500,000 in June 1996 and the remainder in
September 1996. Commencing October 1, 1996, all earnings accrue solely to the
common shareholders.
 
LOANS, CREDIT RISK AND THE ALLOWANCE AND PROVISION FOR POSSIBLE LOAN LOSSES
 
    Total loans increased $24,754,000 or 11% since December 31, 1996 primarily
reflecting the expansion of the consumer loan portfolio and management's
emphasis on indirect automobile financing, which began in late 1995 and has
continued to the present. Consumer loans increased to $42,340,000 or 54% since
December 31, 1996. The Company's emphasis on increasing consumer loans provides
greater diversification within the portfolio and generates higher yields than
residential real estate loans.
 
                                       31
<PAGE>
    Net chargeoffs were $19,000 at September 30, 1997 compared to net chargeoffs
of $21,000 at September 30, 1996. As a percentage of average loans, net
chargeoffs equaled 0.01% respectively for September 30, 1997 and 1996. In prior
periods, the Company has historically outperformed its peer group's net loan
loss average. Although peer group data for the third quarter of 1997 is not yet
available, management believes that trend should continue.
 
    The adequacy of the allowance for loan losses in each subsidiary is reviewed
at least monthly. The determination of the provision amount in any period is
based on management's continuing review and evaluation of loan loss experience,
changes in the composition of the loan portfolio, current economic conditions,
the amount of loans presently outstanding, and the amount and composition of
growth expectations. The allowance for loan losses as of September 30, 1997 is
considered adequate by management.

INVESTMENT SECURITIES
 
    The Company's investment policy prohibits trading activities and does not
allow investment in high-risk derivative products or junk bonds. All investment
securities are classified as "available for sale" ("AFS") and are carried at
fair value with unrealized gains and losses, net of taxes, excluded from
earnings and reported as a separate component of shareholders' equity. A net
unrealized gain of $815,000 was recorded to adjust the AFS portfolio to current
market value at September 30, 1997 compared to a net unrealized gain of $167,000
at December 31, 1996.
 
    At September 30, 1997, the tax equivalent yield of the investment securities
portfolio was 6.60%, compared to 6.45% at December 31, 1996.
 
    Variable rate securities comprised 49% of the total portfolio on September
30, 1997 compared to 50% on December 31, 1996. The weighted average repriceable
life of the portfolio at quarter end was 2.26 years in 1997 compared to 2.06
years at year-end 1996.
 
SOURCES OF FUNDS
 
    Deposits generated within local markets provide the major source of funding
for earning assets. Average total deposits were 90% and 88% of total earning
assets at September 30, 1997 and 1996, respectively. Total interest-bearing
deposits averaged 91% of average total deposits at September 30, 1997 and 1996.
Management is continuing efforts to increase the percentage of
transaction-related deposits to total deposits due to the positive effect on
earnings.

CAPITAL RESOURCES
 
    Common shareholders' equity increased $2,335,000 to $30,084,000 at September
30, 1997 compared to December 31, 1996. The Company redeemed $1,000,000 of its
preferred stock in March 1996, $500,000 in June 1996 and the remaining $500,000
in September 1996.
 
    The Federal Reserve and other regulatory agencies have adopted risk-based
capital guidelines, which assign risk weightings to assets and off-balance sheet
items. Tier 1 capital consists of shareholders' equity less goodwill, while
total capital consists of core capital, certain debt instruments and a portion
of the loan losses. At September 30, 1997, Tier 1 capital to total assets was
8.58%. Total capital to risk-adjusted assets was 14.68%. Both ratios
substantially exceed all required ratios established for bank holding companies.
Risk-adjusted capital levels of the Company's subsidiary Banks exceed regulatory
definitions of well-capitalized institutions.
 
    The Company declared and paid common dividends of $0.26 per share in the
third quarter of 1997 and $0.21 for the same quarter in 1996. Common dividends
declared and paid year-to-date total $0.74 and $0.61 per share respectively for
1997 and 1996. Book value per common share increased to $24.05 from $22.18 at
year-end 1996. The net adjustment for AFS securities increased book value by
$0.39 at September 30, 1997 compared to $0.07 at December 31, 1996.
 
LIQUIDITY
 
    Liquidity management involves maintaining sufficient cash levels to fund
operations and to meet the requirements of borrowers, depositors, and creditors.
Higher levels of liquidity bear higher corresponding costs, measured in terms of
lower yields on short-term, more liquid earning assets, and higher interest
expense involved in extending liability maturities. Liquid assets include cash
and cash equivalents, loans and securities maturing within one year, and money
market instruments. In addition, the Company holds $69,766,000 of AFS securities
maturing after one year which can be sold to meet liquidity needs.
 
    Liquidity is supported by maintaining a relatively stable funding base,
which is achieved by diversifying funding sources, extending the contractual
maturity of liabilities, and limiting reliance on volatile short-term purchased
funds. Short-term funding needs may arise from declines in deposits or other
funding sources, drawdowns of loan commitments and requests for new loans. The
Company's strategy is to fund assets to the maximum extent possible with core
deposits, which provide a sizable source of relatively stable and low-cost
funds. Average core deposits funded approximately 90% and 88% of total earning
assets at September 30, 1997 and 1996, respectively.
 
    Management believes the Company has sufficient liquidity to meet all
reasonable borrower, depositor, and creditor needs in the present economic
environment. The Company has not received any recommendations from regulatory
authorities, which would materially affect liquidity, capital resources or
operations.
 
INTEREST RATE RISK
 
    At September 30, 1997 the Company held approximately $174,179,000 in assets
comprised of securities, loans, short-term investments, and federal funds sold,
which were interest sensitive in one year or less time horizons. The Company's
interest rate sensitivity analysis at September 30, 1997 appears below. Core
deposits are distributed or spread among the various repricing categories based
upon historical patterns of repricing which are reviewed periodically by
management. The assumptions regarding these repricing characteristics greatly
influence conclusions regarding interest sensitivity. Management believes its
assumptions regarding these liabilities are reasonable.
 
    Effective asset/liability management requires the maintenance of a proper
ratio between maturing or repriceable interest-earning assets and
interest-bearing liabilities. It is the policy of the Company that rate-
sensitive assets less rate-sensitive liabilities to total assets are kept within
a range of 80% to 130%.

FACILITIES AND TECHNOLOGY
 
    In an effort to make its services more accessible and convenient, the
Company intends to relocate the Grantline Branch of Regional Bank. Construction
of the new facility is currently in progress, and should be completed in the
fourth quarter of 1997. The Company is also considering the relocation of
certain Union Bank branches. These potential changes will increase visibility,
enhance drive-thru banking and ATM accessibility, and improve ingress and
egress.
 
    During 1996, many technological improvements were initiated. Certain of
these improvements, such as upgrading communication lines, have provided faster
response time for customer transactions. Others represent capital investments,
which allow the Company to continue to effectively compete within a financial
services industry that is becoming increasingly dependent upon technology. In
1997, several hundred thousand dollars is being invested in additional
technology enhancements, such as an automated voice response information system,
additional ATMs, laser printed deposit statements, optical disk storage, and an
increase in the power and memory of the AS400 computer system which will allow
for improved efficiency in the management of computer resources.
 
ACCOUNTING CHANGES
 
    Statement of Financial Accounting Standards ("SFAS") No. 128, EARNINGS PER
SHARE, is effective for the Company's 1997 annual financial statements. This
statement simplifies the calculations of earnings per share. The Company does
not expect the new disclosure for basic earnings per share will be different
from primary earnings per share as currently calculated and disclosed.
Additional disclosures related to the potential dilution that could occur from
unexercised stock options will not affect the Company since it currently has no
stock options plans.
 
    SFAS No. 129, DISCLOSURE OF INFORMATION ABOUT CAPITAL STRUCTURE, continues
the current requirements to disclose certain information about an entity's
capital structure found in various standards. This statement consolidates
specific disclosure requirements from those standards. SFAS No. 129 is effective
for the Company's 1997 annual financial statements.
 
    Management does not expect adoption of these statements to have any material
effect on 1997 financial statements.
 
    SFAS No. 130, REPORTING COMPREHENSIVE INCOME, establishes standards for
reporting and displaying comprehensive income and its components (revenues,
expenses, gains and losses) in a full set of general-purpose financial
statements. This statement does not require a specific format for that financial
statement but requires that an enterprise display an amount representing total
comprehensive income for the period in that financial statement.
 
                                       34
<PAGE>
    SFAS No. 130 will also require the Company to (a) classify items of other
comprehensive income by their nature in a financial statement and (b) display
the accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position.
 
    SFAS No. 130 is effective for fiscal years beginning after December 15,
1997. Reclassification of financial statements for earlier periods provided for
comparative purposes is required.
 
    SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED
INFORMATION, establishes standards for the way public business enterprises
report information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports to shareholders. It also establishes
standards for related disclosures about products and services, geographic areas
and major customers.
 
    SFAS No. 131 does not apply to nonpublic enterprises or to not-for-profit
organizations.
 
    SFAS No. 131 requires that a public business enterprise report financial and
descriptive information about its reportable operating segments. Operating
segments are components of an enterprise about which separate financial
information is available that is evaluated regularly by the chief operating
decision-maker in deciding how to allocate resources and in assessing
performance. Generally, financial information is required to be reported on the
basis that it is used internally for evaluating segment performance and deciding
how to allocate resources to segments.
 
    SFAS No. 131 requires that a public business enterprise report a measure of
segment profit or loss, certain specific revenue and expense items and segment
assets. It requires reconciliation of total segment revenues, total segment
profit or loss, total segment assets and other amounts disclosed for segments to
corresponding amounts in the enterprise's general purpose financial statements.
SFAS No. 131 also requires that a public business report descriptive information
about the way that the operating segments used in reporting were determined, the
products and services provided by the operating segments, differences between
the measurements used in reporting segment information and those used in the
enterprise's general purpose financial statements and changes in the measurement
of segment amounts from period to period.
 
    SFAS No. 131 is effective for financial statements for periods beginning
after December 15, 1997. In the initial year of application, comparative
information for earlier years is to be restated. SFAS No. 131 need not be
applied to interim financial statements in the initial year of its application,
but comparative information for interim periods in the initial year of
application is to be reported in financial statements for interim periods in the
second year of application.
 
    Management has not yet determined the effect of implementing SFAS Nos. 130
and 131.
 
YEARS ENDED DECEMBER 31, 1994, 1995 AND 1996
 
OVERVIEW
 
    The Company operates under the broad tenets of a long-term strategic plan
("Plan") designed to improve the Company's financial performance, expand its
competitive ability and enhance long-term shareholder value. The Plan is
premised on the belief of the Company's board of directors that the Company can
best promote long-term shareholder interests by pursuing strategies which will
continue to preserve it's community-focused philosophy.
 
    In conformance with the Plan, during 1994, the Company consolidated the
operations of its two commercial banking subsidiaries to form Union Bank, and
sold three underperforming branches of Regional Bank. The Company believes each
of those actions increased its operating efficiency and the latter improved its
net interest margin. The Plan also focused on improving net interest margin by
reducing the Company's dependence on expensive, non-core deposits.
 
                                       35
<PAGE>
    During 1995, the Company initiated actions intended to build a stronger
customer base in its primary markets. The Company invested approximately
$500,000 to renovate Regional Bank's main office, providing direct lobby access
of all customer service and loan personnel, and greatly improving drive-up and
electronic banking services. Unlike many of the large super regional banks,
which are closing branches in record numbers, the Company believes it is
important to maintain community banking centers. Accordingly, an additional
$500,000 was invested to create two new branch offices. The Allison Lane branch
in Jeffersonville was opened by Regional Bank to provide greater access to
present and prospective customers in Clark County. Union Bank opened the IGA
supermarket branch in Greensburg, exclusively providing seven-day banking and
extended hours to the community. In an effort to make its services more
accessible and convenient, the Company intends to relocate the Grantline Branch
of Regional Bank. The Company is also considering the relocation of certain
Union Bank branches. These potential changes are designed to increase
visibility, enhance drive-thru banking and ATM accessibility, and improve
ingress and egress.
 
    A continuing tenet of the Plan is to establish and cultivate more proactive
relationships with financial analysts and market makers in the Company's stock.
As a result of our relationship-building efforts, Stifel, Nicolaus & Company,
Incorporated, based in St. Louis, Missouri, became a market maker in Indiana
United Bancorp shares in November, 1996, joining current market makers J.J.B.
Hilliard/W.L. Lyons, Inc. and NatCity Investments, Inc.
 
    The Company initiated a sales philosophy in 1995 supported by a
performance-based employee incentive program. The initial phase of this program
included sales training for all customer service personnel. In 1996, sales
training evolved to encompass all customer contact personnel. Customer service
personnel now receive advanced sales training in order to become more effective
in cross-selling techniques. The performance-based employee incentive program
earned over $121,000 in 1996 for employees engaged in all facets of the Company.
 
    During 1996, many technological improvements were initiated. Certain of
these improvements, such as upgrading communication lines, have provided faster
response time for customer transactions. Others represent capital investments
which allow the Company to continue to effectively compete within a financial
services industry that is becoming increasingly dependent upon technology. In
1997, several hundred thousand dollars are budgeted for additional technology
enhancements, such as an automated voice response information system, additional
ATMs, laser printed deposit statements, optical disk storage, and an increase in
the power and memory of the AS400 computer system which will allow for improved
efficiency in the management of computer resources.
 
    The dynamics of the Plan assure continually evolving goals, and the extent
of the Company's success will depend upon how well it anticipates and responds
to competitive changes within its markets, the interest rate environment and
other external forces.
 
RESULTS OF OPERATIONS
 
    Annual net income ranged between $2,529,000 and $2,870,000 for the past
three years. Significant nonrecurring items impacted net income in 1994 and
1996. In 1994, earnings included a $1,229,000 gain on the sale of three
under-performing Regional Bank branches and a loss of $154,000 on the sale of
securities. These nonrecurring items resulted in additional net income of
$650,000. The Federal omnibus spending package enacted on September 30, 1996,
together with companion legislation enacted earlier in the year, resulted in a
$474,000 reduction of 1996 net income. The legislation imposed a special
assessment on thrift institutions to recapitalize the SAIF, resulting in a
pre-tax charge of $545,000. Additionally, a tax advantage available to thrift
institutions in the calculation of allowable tax bad debt reserves was
eliminated, granting forgiveness of any tax liability prior to 1987, but
resulting in an income tax expense of $145,000 on the bad debt reserve recapture
since January 1, 1987. See "--Income Taxes." Excluding these nonrecurring
 
                                       36
<PAGE>
charges, net income for 1996 was $3,166,727, a 25% increase over the prior year.
There were no significant nonrecurring income or expense items in 1995.
 
    Non-interest income in 1996 reflects a decline in insurance commissions due
mainly to lower levels of profit sharing received from participating companies
based on claims experience for the year. Trust income and service charge income
increased over the prior year. Non-interest expense reflects reduced FDIC
assessments, excluding the special assessment mentioned previously, due to a
lower deposit insurance assessment rate. Professional fees increased in 1996 as
compared to the prior year.
 
    Net income per common share from recurring operations equaled $2.49 in 1996,
compared to $1.91 in 1995, and $1.58 in 1994. Including the FDIC special
assessment and bad debt recapture expense, 1996 earnings equaled $2.11 per
share. The gain realized on the sale of Regional Bank's branches increased 1994
earnings per share by $0.59.
 
    The Company's return on average total assets was 0.85% in 1996, 0.82% in
1995, and 0.86% in 1994. Excluding nonrecurring charges, return on average
assets for 1996 was 1.00%. Return on average common shareholders' equity during
these three years was 9.89%, 9.73%, and 12.18%, respectively. Excluding non-
recurring charges, return on average common shareholders' equity for 1996 was
11.58%.
 
NET INTEREST INCOME
 
    Net interest income is influenced by the volume and yield of earning assets
and the cost of interest-bearing liabilities. Net interest margin reflects the
mix of interest-bearing and non-interest-bearing liabilities that fund earning
assets, as well as interest spreads between the rates earned on these assets and
the rates paid on interest-bearing liabilities. Net interest income of
$12,056,000 in 1996 reflects a 9% increase from $11,095,000 in 1995, which was
3% below 1994.
 
    Throughout 1996, the Company employed a deposit-pricing strategy focused on
retaining and attracting lower cost, short-to-medium term funds. Management
correctly anticipated a relatively flat rate environment throughout 1996 and
into 1997. The Company believes this strategy greatly enhanced 1996 net interest
income and will also have a positive effect on 1997 earnings. Although many of
the Company's peer group competitors reported flat or marginally changed net
interest margins for the full year 1996, the Company increased its net interest
margin by 23 basis points. Since year-end 1993, the Company has increased its
net interest margin by 48 basis points.
 
    The changes in interest income and interest expense resulting from changes
in volume and rate are summarized in the following tables. Variances have been
allocated on the basis of the absolute relationship between volume and rate.

PROVISION FOR LOAN LOSSES
 
    This topic is discussed under the heading "--Loans, Credit Risk and the
Allowance and Provision for Possible Loan Losses."
 
NON-INTEREST INCOME
 
    Non-interest income normalized in 1996 and 1995 after benefiting from a gain
of $1,229,000 from the sale of branches in 1994. Non-interest income in 1996
exceeded 1995 by $45,000 or 3%. Excluding the sale of branches, non-interest
income in 1995 exceeded 1994 by $98,000 or 7%. There were no securities gains or
losses in 1996, versus a $16,000 gain in 1995 and a loss of $154,000 in 1994.
 
    Insurance commissions continue to represent the largest component of
recurring non-interest income, equaling 29%, 32% and 37% in 1996, 1995 and 1994.
Declines of $36,000 and $71,000 in 1995 and 1994 primarily reflected
reorganization and relocation disruptions of insurance operations in Jay County.
The current year decline of $35,000 represents the loss of year-end profit
sharing programs from primary carriers due to 1996 claims experience. Trust
income increased $43,000 over 1995, fueled by a $12,000 increase in estate
income and a strong stock market in 1996. The level of estate assets
administered may cause trust income to fluctuate significantly from year to
year. Service charges on deposit accounts increased in 1996 by $70,000, or 16%,
primarily due to the strong growth in a new interest-bearing checking account
introduced in early 1996. Deposit growth and interest rate variables also
affected service charge income in 1996. Service charges on deposit accounts
decreased in both 1995 and 1994 compared to
 
                                       39
<PAGE>
prior years. It is anticipated that in 1997 the Company will experience
additional deposit growth, generating even higher service charge income.
 
NON-INTEREST EXPENSE
 
    The largest component of non-interest expense is personnel expense.
Personnel expenses increased in 1996 by $15,000, or less than 1%, after
declining by $86,000 in 1995. The average number of full-time equivalent
employees in 1996 was four persons less than the average 1995 staffing level,
which was fifteen persons less than 1994. Improvements in technology implemented
throughout 1996 enabled the Company to effectively control staffing levels.
Normal staff salary adjustments and increased benefit costs were incurred in
both 1996 and 1995, including $121,000 and $53,000 in 1996 and 1995,
respectively, earned by employees in connection with the performance incentive
compensation plan. Although certain employee benefit costs increased in 1996,
health care benefit costs decreased. Personnel expenses in 1997 are not expected
to change materially from 1996.
 
    Deposit insurance, excluding the $545,000 special assessment, was $205,000
less in 1996 than the prior year, due to a lower rate on which the insurance
premium was calculated. In mid-1995, the FDIC reduced deposit insurance premiums
paid by soundly managed banks, including Union Bank, by 83%. Since the bank
insurance fund reached a mandated funding level in 1995, the assessment rate for
the Company's commercial bank was further reduced to the $2,000 minimum level
permissible in 1996.
 
    After two long years of debate, Congress finally agreed to a legislative
package to adequately capitalize the SAIF. This legislation was included in the
Federal omnibus spending package enacted on September 30, 1996. It required the
thrift industry to recapitalize the SAIF with a one-time assessment and delayed
a PRO RATA sharing of the FICO bond interest payments for three years. The
one-time assessment imposed on Regional Bank equaled approximately $545,000.
 
    For the next three years, thrift institutions will pay approximately five
times higher assessment rates than commercial banks (6.44 cents versus 1.29
cents per $100 of deposits), but this is a significant reduction from the 23
cents per $100 of deposits assessed prior to September 30, 1996. After the three
year period, commercial banks and thrifts will pay the same assessment rate of
2.43 cents per $100 of deposits. Based on current deposit levels and projected
growth, Regional Bank will save approximately $540,000 in the next three years
due to the lower assessment rate.

INCOME TAXES
 
    On August 20, 1996, President Clinton signed into law the Small Business Job
Protection Act of 1996. Included within this tax legislation was the repeal of
certain tax advantages to thrifts applicable to tax bad debt provision
calculations. The bill eliminated the percent-of-taxable-income method for
computing tax liability on additions to thrift's bad debt reserves for years
beginning after December 31, 1995. The bill also required that thrift
institutions recapture all or a portion of their tax bad debt reserves added
since December 31, 1987. Accordingly, income tax expense of $145,000 was
recorded on the tax bad debt recapture in 1996, resulting primarily from the
decrease in loans included in the sale of Regional Bank's branches in 1994. The
unrecaptured base year tax reserve will not be subject to recapture, as long as
the institution continues to carry on the business of banking and meets other
criteria.
 
    The effective tax rate was 40% for 1996, 40% in 1995 and 39% in 1994. The
Company and its subsidiaries filed consolidated income tax returns for 1996.
 
FINANCIAL CONDITION
 
    Total average assets in 1996 increased $9,244,000 over the prior year.
Average assets declined by $27,188,000 in 1995 as compared to 1994, primarily
due to deposit pricing strategies and the sale of branches in October 1994. For
comparability, average assets in 1994 would have been $20,000,000 less if the
branch sale had occurred on January 1, 1994. Changes in average assets in 1995
and 1996 reflect normalized operations.
 
    Year-end assets increased to $328,346,000 from $313,067,000 at December 31,
1995. Cash, cash equivalents and short-term investments increased at year-end
1995 to provide funding for loans scheduled
 
                                       41
<PAGE>
to close shortly after December 31, 1995. Securities maturities and repayments,
as well as increased levels of interest-bearing deposits, were used to fund loan
growth in 1996.
 
    Average earning assets have represented 95% of average total assets for the
past three years. Average loans represent approximately 66% of average assets in
1996 compared to 65% in 1995 and 62% in 1994. Management intends to continue its
emphasis on loan growth in 1997.
 
    Average non-interest-bearing deposits increased less than 1% in 1996
compared to a 4% increase in 1995. Average interest-bearing deposits increased
$11,981,000 or 5% in 1996 compared to 1995. Average interest-bearing demand
deposits increased $1,924,000, primarily due to the success of a new interest-
bearing checking account introduced early in 1996. Average savings accounts
increased 8% due to the continued success of a premium passbook savings account
introduced in 1995. Money market investment accounts decreased 11% as compared
to the prior year due to the shifting of funds to the new interest-bearing
demand account and the premium savings passbook account. Average certificates of
deposit and other time deposit increased approximately $11,557,000 in 1996,
primarily in certificates of deposit of $100,000 and over.

    Long-term debt is primarily the Company's loan for the purchase of Regional
Bank and is secured by the capital stock of the Company's Subsidiary Banks. The
Company successfully renegotiated the rate with the lender, effective July 1,
1995. Interest adjusts quarterly to the lender's prime rate, less 25 basis
points. The Company believes it has complied with all terms and covenants of the
loan agreement. The Company prepaid $250,000 on long-term debt in 1996, and
$750,000 in 1995. A principal payment of $375,000 is due June 30, 1997 and the
balance of the loan is due December 31, 1997. Prior to that time, the Company
intends to negotiate the refinancing of its long-term borrowing needs. See
"--Nine Months Ended September 30, 1996 and 1997--Financial Condition."
 
    Shareholders' equity was $27,749,000 on December 31, 1996 compared to
$28,245,000 on December 31, 1995. Book value per common share increased to
$22.18 or 6% from $20.98 at year end 1995. The unrealized gain on securities
available for sale, net of taxes, totaled $95,000 or $.07 per share at December
31, 1996 compared to an unrealized gain of $195,000 or $.15 at December 31,
1995. Excluding the net unrealized gains or losses on securities available for
sale, book value per share was $22.11 at

December 31, 1996, or an increase of 6% over the comparable book value at year
end 1995. In 1995, $400,000 of preferred stock was redeemed. The Company
redeemed the remaining $2,000,000 of its preferred stock in 1996. All future
earnings available to shareholders will now accrue solely to the common
shareholders until such time, if any, as the Company sells additional preferred
stock.

LOANS, CREDIT RISK AND THE ALLOWANCE AND PROVISION FOR POSSIBLE LOAN LOSSES
 
    Loans remain the Company's largest concentration of assets and continue to
represent the greatest risk. The loan underwriting standards observed by each of
the Company's subsidiaries are viewed by management as a deterrent to the
emergence of an abnormal level of problem loans and a subsequent increase in net
chargeoffs. The Company's conservative loan underwriting standards have
historically resulted in higher loan quality and lower levels of net chargeoffs
than peer bank averages. The Company also believes credit risks may be elevated
if undue concentrations of loans in specific industry segments and to
out-of-area borrowers are incurred. Accordingly, the Company's board of
directors regularly monitors such concentrations to determine compliance with
its restrictive loan allocation policy. The Company believes it has no undue
concentrations of loans.
 
    Total loans increased 9%, primarily reflecting the expansion of the consumer
loan portfolio and management's emphasis on indirect automobile financing which
began in late 1995 and has continued to the present. Consumer loans increased
50% in 1996. The Company's emphasis on increasing consumer loans provides
greater diversification within the portfolio and generates higher yields than
residential real estate loans. Although the Company limits its exposure to
long-term fixed rate residential mortgage loans and generally observes 20%
minimum downpayment guidelines, it originated both fixed rate loans and loans
with little or no downpayment for a noncompeting mortgage lender during 1996.
This program assisted the Company in serving all segments of the community
without incurring unacceptable levels of credit exposure or interest rate risk.
The origination of these loans provides fee income.

    The Company regards its ability to identify and correct loan quality
problems as one of its greatest strengths. Loans are placed in a nonaccruing
status when in management's judgment the collateral value and/or the borrower's
financial condition does not justify accruing interest. As a general rule,
commercial and real estate loans are reclassified to nonaccruing status at or
before becoming 90 days past due. Interest previously recorded but not deemed
collectible is reversed and charged against current income. Subsequent interest
payments collected on nonaccrual loans may thereafter be recognized as interest
income or may be applied as a reduction of the loan balance, as circumstances
warrant. Non-real estate secured consumer loans are not placed in nonaccruing
status, but are charged off when policy-determined delinquent status is reached.
 
    Net chargeoffs were $398,000 in 1996, $60,000 in 1995 and $13,000 in 1994.
As a percentage of average loans, net chargeoffs equaled 0.19%, 0.03% and 0.01%
in 1996, 1995 and 1994, respectively. The increase in 1996 was caused primarily
by the $334,000 chargeoff of portions of two loans currently held by Regional
Bank. In each of the previous two periods, the Company significantly
outperformed its peer group's net loan loss average.
 
    Foreclosed real estate held by the Company at December 31, 1996 totaled
$1,000,000 and consisted of a single property. The property is expected to be
sold by mid-year 1997 with minimal gain or loss realized. After the sale,
foreclosed real estate will decrease to a level more closely mirroring prior
years. See
 
"--Nine Months Ended September 30, 1996 and 1997--Results of Operations."
 
    Management maintains a listing of loans warranting either the assignment of
a specific reserve amount or other special administrative attention. This
listing, together with a listing of all classified loans, nonaccrual loans and
loans delinquent 30 days or more, is reviewed monthly by the board of directors
of each subsidiary.
 
    The ability to absorb loan losses promptly when problems are identified is
invaluable to a banking organization. Most often, losses incurred as a result of
prompt, aggressive collection actions are much lower than losses incurred after
prolonged legal proceedings. Accordingly, the Company observes the practice of
quickly initiating stringent collection efforts in the early stages of loan
delinquency.
 
    The adequacy of the allowance for loan losses in each subsidiary is reviewed
at least monthly. The determination of the provision amount in any period is
based on management's continuing review and
 
                                       45
<PAGE>
evaluation of loan loss experience, changes in the composition of the loan
portfolio, current economic conditions, the amount of loans presently
outstanding, and the amount and composition of growth expectations. The
allowance for loan losses as of December 31, 1996, is considered adequate by
management.

    The allocation is based primarily on previous credit loss experience,
adjusted for changes in the risk characteristics of each category. Additional
amounts are allocated based on an evaluation of the loss potential of individual
troubled loans and the anticipated effect of economic conditions on both
individual loans and loan categories. Because the allocation is based on
estimates and subjective judgment, it is not necessarily indicative of the
specific amounts or loan categories in which losses may ultimately occur.
 
    SFAS No. 122, ACCOUNTING FOR MORTGAGE SERVICING RIGHTS, pertains to mortgage
banking and financial institutions that conduct operations that are
substantially similar to the primary operations of a mortgage banking
enterprise. SFAS No. 122 eliminates the accounting distinction between mortgage
servicing rights that are acquired through loan origination activities and those
acquired through purchase transactions. Under SFAS No. 122, if the Company
enters into mortgage banking activities and sells or securitizes loans and
retains the mortgage servicing rights, the Company must allocate the total cost
of the mortgage loans to the mortgage servicing rights and the loans (without
the rights) based on their relative fair values.
 
    SFAS No. 122 was effective for the Company in 1996. Since the Company does
not currently engage in mortgage banking activities, the adoption of SFAS No.
122 did not have any material effect on 1996 operations or financial position.
 
INVESTMENT SECURITIES
 
    Investment securities offer flexibility in the Company's management of
interest rate risk, and are the primary means by which the Company provides
liquidity and responds to changing maturity characteristics of assets and
liabilities. The Company's investment policy prohibits trading activities and
does not allow investment in high risk derivative products or junk bonds.
 
    In 1994, the Company adopted new accounting rules for securities. The rules
require that each security must be individually designated as a held to maturity
("HTM") security or as an AFS security. Late in 1995, the Financial Accounting
Standards Board ("FASB") allowed an unprecedented "one time" transition
reclassification. While more than 90% of the Company's investments were already
designated AFS, the Company took this opportunity to reclassify all remaining
HTM securities to AFS to provide even greater management flexibility in
responding to changes within financial markets.
 
                                       47
<PAGE>
    As of December 31, 1996, all investment securities are classified as AFS and
are carried at fair value with unrealized gains and losses, net of taxes,
excluded from earnings and reported as a separate component of shareholders'
equity. An unrealized gain of $167,000 was recorded to adjust the AFS portfolio
to current market value at December 31, 1996, compared to an unrealized gain of
$333,000 at December 31, 1995.
 
    At year end 1996, the tax equivalent yield of the investment securities
portfolio was 6.45%, representing an increase from 6.33% at year end 1995, and
6.16% at year end 1994.
 
    In 1994, management began to reduce the variable portion of the investment
securities portfolio. Variable rate securities comprised 50% of the total
portfolio on December 31, 1996 compared to 55% and 65% on December 31, 1995 and
1994. The reduction of variable rate securities extended the year end weighted
average repriceable life of the portfolio to 2.06 years compared to 1.14 years
in 1995.

    taxes reduced by nondeductible portion of interest expense.
 
    Amounts in the table above are based on scheduled maturity dates. Variable
interest rates are subject to change not less than annually based upon certain
interest rate indexes. Expected maturities will differ from contractual
maturities because issuers may have the right to call or prepay obligations with
or without call or prepayment penalties.
 
    As of December 31, 1996, there are no corporate bonds and other securities
which represent more than 10% of shareholders' equity.
 
SOURCES OF FUNDS
 
    The Company relies primarily on customer deposits and securities sold under
repurchase agreements, along with shareholders' equity, to fund earning assets.
On an infrequent basis, Federal Home Loan Bank ("FHLB") advances are used to
provide additional funds.
 
    Deposits generated within local markets provide the major source of funding
for earning assets. Average total deposits were 88% and 86% of total earning
assets in 1996 and 1995. Total interest-bearing deposits averaged 91%, 90% and
92% of average total deposits during 1996, 1995 and 1994. Management is
continuing efforts to increase the percentage of transaction-related deposits to
total deposits due to the positive effect on earnings.
 
                                       48
<PAGE>
    Securities sold under repurchase agreements ("repos") are high denomination
investments utilized by public entities and commercial customers as an element
of their cash management responsibilities. Repos are not subject to FDIC
assessment so they are less costly than large certificates of deposit. With the
reduction in the FDIC assessment, repos do not offer as much cost advantage as
previously experienced. Management utilized large denomination certificates of
deposit in 1996 to replace a portion of customer funds previously invested in
repos.
 
    Even though short-term borrowings temporarily increased 18% at year end 1996
compared to 1995, the Company decreased average repos and other short-term
borrowings in 1996 to $13,316,000 or 17% below 1995. FHLB advances which matured
in early 1996 represented most of the decrease. The FHLB advances were used to
fund loans and other earning assets of Regional Bank in 1995. Depending upon the
level of loan demand, management may again elect to use FHLB advances in 1997 as
part of its cash management strategy.
 
    Information related to repurchase agreements is shown in the table below and
information on other short-term borrowings is not required since the average
balances outstanding during the periods were less than 30% of shareholders'
equity.

    The Company continued to prepay long-term debt in 1996. Long-term debt
decreased $1,000,000 in 1996 of which $250,000 represented reductions in excess
of scheduled payments. Management may continue its history of accelerated
payments in 1997. On December 31, 1997 the remaining balance is due. Prior to
that time, the Company intends to negotiate the refinancing of its long-term
borrowing needs.
 
CAPITAL RESOURCES
 
    Common shareholders' equity increased $1,504,000 to $27,749,000 at December
31, 1996. Total shareholders' equity declined by $496,000 due primarily to the
early redemption of $2,000,000 of preferred stock in 1996. Redemptions in 1995
and 1994 totaled $400,000 and $300,000. All of the preferred shares have now
been redeemed.
 
    The Federal Reserve and other regulatory agencies have adopted risk-based
capital guidelines which assign risk weightings to assets and off-balance sheet
items. The Company's Tier 1 capital consists of shareholders' equity less
goodwill, while total capital consists of core capital, certain debt instruments
and a portion of the allowance for credit losses. At December 31, 1996, Tier 1
capital to total assets was 8.31%. Total capital to risk-adjusted assets was
15.05%. Both ratios substantially exceed all required ratios established for
bank holding companies. Risk-adjusted capital levels of the Company's subsidiary
banks exceed regulatory definitions of well-capitalized institutions.
 
    Shareholders' equity is impacted by the Company's decision to categorize its
entire securities portfolio as AFS under accounting rules adopted January 1,
1994. Securities in this category are carried at fair value, and shareholders'
equity is adjusted to reflect unrealized gains and losses, net of taxes.
 
    The Company declared and paid common dividends of $0.83 per share in 1996
and $0.69 in 1995. Book value per common share increased to $22.18 from $20.98
in 1995. The net adjustment for AFS securities increased book value by $0.07 and
$0.15 at December 31, 1996 and 1995. Depending on market
 
                                       49
<PAGE>
conditions, the adjustment for AFS securities can cause significant fluctuations
in equity. The dividend payment rate on preferred stock was 6.34% during each of
the past two years.
 
LIQUIDITY
 
    Liquidity management involves maintaining sufficient cash levels to fund
operations and to meet the requirements of borrowers, depositors, and creditors.
Higher levels of liquidity bear higher corresponding costs, measured in terms of
lower yields on short-term, more liquid earning assets, and higher interest
expense involved in extending liability maturities. Liquid assets total
$47,810,000, and include cash and cash equivalents, loans and securities
maturing within one year, and money market instruments. In addition, the Company
holds $75,667,000 of AFS securities maturing after one year which can be sold to
meet liquidity needs.
 
    Liquidity is supported by maintaining a relatively stable funding base,
which is achieved by diversifying funding sources, extending the contractual
maturity of liabilities, and limiting reliance on volatile short-term purchased
funds. Short-term funding needs can arise from declines in deposits or other
funding sources, drawdowns of loan commitments and requests for new loans. The
Company's strategy is to fund assets to the maximum extent possible with core
deposits, which provide a sizable source of relatively stable and low-cost
funds. Average core deposits funded approximately 89% of total earning assets at
December 31 in each of the last three years.
 
    Management believes the Company has sufficient liquidity to meet all
reasonable borrower, depositor, and creditor needs in the present economic
environment. The Company has not received any recommendations from regulatory
authorities which would materially affect liquidity, capital resources or
operations.
 
INTEREST RATE RISK
 
    At year end 1996, the Company held approximately $169,349,000 in assets
comprised of securities, loans, short-term investments, and federal funds sold,
which were interest sensitive in one year or less time horizons. The Company's
interest rate sensitivity analysis for the year ended December 31, 1996 appears
in the following table. Core deposits are distributed or spread among the
various repricing categories based upon historical patterns of repricing which
are reviewed periodically by management. The assumptions regarding these
repricing characteristics greatly influence conclusions regarding interest
sensitivity. Management believes its assumptions regarding these liabilities are
reasonable.
 
    Effective asset/liability management requires the maintenance of a proper
ratio between maturing or repriceable interest-earning assets and
interest-bearing liabilities. It is the policy of the Company that rate-
sensitive assets less rate-sensitive liabilities to total assets be kept within
a range of 80% to 130%.
 
    The Company will seek to attain a more neutral gap position in 1997 based
upon the belief that the current interest rate environment will remain
relatively stable throughout 1997. In any event, the Company does not anticipate
that its earnings will be materially impacted in 1997, regardless of the
direction interest rates may trend.

EFFECTS OF CHANGING PRICES
 
    The Company's asset and liability structure is substantially different from
that of an industrial company in that most of its assets and liabilities are
monetary in nature. Management believes the impact of inflation on financial
results depends upon the Company's ability to react to changes in interest rates
and, by such reaction, reduce the inflationary impact on performance. Interest
rates do not necessarily move in the same direction at the same time, or at the
same magnitude, as the prices of other goods and services. As discussed
previously, management relies on its ability to manage the relationship between
interest-sensitive assets and liabilities to protect against wide interest rate
fluctuations, including those resulting from inflation.
 
ACCOUNTING CHANGES
 
    The FASB has issued SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF
LONG-LIVED ASSETS TO BE DISPOSED OF. This statement establishes guidance for
recognizing and measuring impairment losses and requires that the carrying
amount of impaired assets be reduced to fair value. Long-lived assets and
certain identifiable intangibles must be reviewed for impairment whenever events
indicate that the carrying amount of the assets may not be recoverable.
 
    SFAS No. 121 was effective in 1996 for the Company. The adoption of SFAS No.
121 did not have any material effect on results of operation or financial
condition in 1996.
 
    SFAS No. 123, STOCK BASED COMPENSATION, was effective for the Company in
1996. This statement requires expanded disclosures rather than recognition of
compensation cost as was originally required by the exposure draft of this
statement for fixed, at the money, options. However, employers are encouraged to
recognize the cost of stock-based compensation plans in their financial
statements. Currently, the Company has no stock-based compensation plans and
adoption of SFAS No. 123 did not have any effect on 1996 financial statements.
 
    SFAS No. 125, ACCOUNTING FOR TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND
EXTINGUISHMENTS OF LIABILITIES, provides consistent standards for distinguishing
transfers of financial assets that are sales from transfers that are considered
secured borrowings.
 
    A transfer of financial assets in which the transferor surrenders control
over those assets is accounted for as a sale to the extent that consideration
other than beneficial interests in the transferred assets is
 
                                       51
<PAGE>
received in exchange. The transferor has surrendered control over transferred
assets only if certain conditions are met.
 
    This statement provides detailed measurement standards for assets and
liabilities included in these transactions. It also includes implementation
guidance for assessing isolation of transferred assets and for accounting for
transfers of many specific types of transactions.
 
    Except as amended by SFAS No. 127, SFAS No. 125 is effective for transfers
and servicing of financial assets and extinguishments of liabilities occurring
after December 31, 1996 and is to be applied prospectively. Earlier or
retroactive application is not permitted. SFAS No. 127 defers for one year the
effective date (a) of paragraph 15 of SFAS No. 125 and, (b) for repurchase
agreement, dollar-roll, securities lending, and similar transactions, of
paragraphs 9-12 and 237(b) of SFAS No. 125.
 
    SFAS No. 127 provides additional guidance on the types of transactions for
which the effective date of SFAS No. 125 has been deferred. It also requires
that if it is not possible to determine whether a transfer occurring during
calendar-year 1997 is part of a repurchase agreement, dollar-roll, securities
lending, or similar transaction, then paragraphs 9-12 of SFAS No. 125 should be
applied to that transfer.
 
    Management does not expect adoption of these statements to have any material
effect on 1997 financial statements.

 PTC MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATIONS
 
    CERTAIN STATEMENTS IN THIS SECTION CONSTITUTE "FORWARD-LOOKING STATEMENTS"
WITHIN THE MEANING OF SECTION 27A OF THE SECURITIES ACT AND SECTION 21E OF THE
EXCHANGE ACT. SUCH FORWARD-LOOKING STATEMENTS INVOLVE KNOWN AND UNKNOWN RISKS,
UNCERTAINTIES AND OTHER FACTORS THAT MAY CAUSE ACTUAL RESULTS, PERFORMANCE OR
ACHIEVEMENTS OF THE COMPANY OR PTC TO DIFFER MATERIALLY FROM ANY FUTURE RESULTS,
PERFORMANCE OR ACHIEVEMENTS EXPRESSED OR IMPLIED BY SUCH FORWARD-LOOKING
STATEMENTS.
 
GENERAL
 
    The business of PTC consists of holding and administering its interest in
People's Trust. The principal business of People's Trust consists of attracting
deposits from consumer and commercial customers and making loans to individuals
and businesses. People's Trust offers various products for depositors, including
checking and savings accounts, certificates of deposit and safe deposit boxes.
Loans consist principally of loans to individuals secured by mortgage liens on
residential properties, consumer loans generally secured by liens on personal
property, and loans to businesses generally secured by liens on business assets
such as inventory, accounts receivable, commercial real estate and other
property. People's Trust also offers trust services to individuals, businesses
and institutions.
 
    People's Trust operates 17 banking offices in nine eastern and southeastern
counties in Indiana. In 1996, People's Trust opened new banking offices in the
Greensburg and Connersville markets and in the first quarter of 1997 purchased
an office in Hanover. People's Trust will continue to take advantage of
opportunities to expand its number of locations if the expansion appears to
represent a profitable opportunity, however, there is no assurance this
expansion will occur.
 
NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1997
 
RESULTS OF OPERATIONS
 
    Net income for the nine months ended September 30, 1997 was $2,702,000
compared to $2,391,000 for the same period in 1996, which represented a $311,000
or 13.0% increase. Earnings per share also increased from $2.31 per share to
$2.64 per share for the same period. Higher net interest income, which was
partially offset by higher non-interest expense, accounted for most of the
increase in net income. Net income and earnings per share for the third quarter
of 1997 versus the third quarter of 1996 were also higher. Again, higher net
interest income, offset by higher non-interest expenses, were the main
contributors.
 
    For the nine-month period ended September 30, 1997, as compared to the same
period in 1996, net interest income increased by $872,000 or 11.3%. A similar
proportional increase also occurred during the third quarter of 1997 versus the
third quarter of 1996. Higher volumes (average balances) of financial assets and
liabilities, rather than changes in underlying interest rates, were the main
reason for increased interest income and interest expense. Average loans were
$209,000,000 for the nine months ended September 30, 1997 compared to
$181,300,000 for the same period in 1996, or about $27,700,000 higher. Average
deposits were $266,900,000 for the nine-month period ended September 30, 1997
versus $243,900,000 for 1996, or about $23,000,000 higher. Net interest margin
(net interest income on a tax equivalent basis divided by average total earnings
assets) was 4.46% for the nine-month period ended September 30, 1997 and 4.38%
for the same period in 1996.
 
    Non-interest income was relatively stable for the nine-month period ended
September 30, 1997 versus 1996; however, certain components of non-interest
income did change significantly. Mortgage banking income, which consists of
gains (losses) on loan sales and service fee income, was $103,000 higher for the
third quarter of 1997 versus 1996, and $189,000 higher for the nine-month period
ended September 30,
 
                                       53
<PAGE>
1997 versus 1996. During the second and third quarters, the long-term interest
rates charged on mortgages declined and PTC saw an increase in refinancing and
new originations take place. Gains on securities included a sale of common stock
in 1996, but was a one-time gain and therefore not reported in 1997.
 
    Non-interest expense increased from $5,272,000 for the nine months ended
September 30, 1996 to $5,918,000 for the same period in 1997, or a $646,000
increase. Most of this increase was related to higher salaries and benefits and
higher occupancy and equipment expense. Higher salary and benefit costs were
directly attributed to a revised management structure which was implemented on
January 1, 1997; and called for the hiring of several new commercial lenders, a
financial controller, an executive vice president, and several regional sales
managers so PTC could be better positioned for additional growth and loan
production activity.
 
    Higher occupancy and equipment expenses were directly attributed to PTC's
expansion of its current ATM program which included the refurbishing of four
existing ATM's, the addition of four new ATM's and the addition of one cash
dispenser at an Indiana convenience store. PTC also converted to a new network
and service provider in order to attain long term cost reductions in driving the
ATM network. In addition, PTC expanded its branch network by acquiring a full
service branch in March 1997 in Hanover, Indiana, and establishing a de novo
branch in Madison, Indiana in September 1997.
 
FINANCIAL CONDITION
 
    Total assets increased slightly by $6,158,000 or 2.1% from December 31, 1996
to September 30, 1997. Gross loans increased by $23,690,000 or 12.0% during the
same period. A decline in cash equivalents of $7,904,000 was used to fund the
increase in loans, along with sales and maturities of available-for-sale
securities. Loan demand continued to be strong in 1997. PTC believes it has
positioned itself to grow its loan portfolio by adding employees to increase
originations. As of September 30, 1997, PTC had obtained an 80.0% loan to
deposit ratio. A detailed presentation of loans by category follows:

    PTC maintains a watch list and performs an ongoing loan review function. On
a quarterly basis the allowance for loan loss calculation is completed. While
management believes that the allowance is adequate as of September 30, 1997, it
intends to significantly fund the provision during the fourth quarter because
PTC's overall loan growth exceeded 13.5% in 1996 and will exceed 14% growth in
1997. A comparative review of the PTC's allowance for loan loss to its peer
group, which consists of financial institutions between $150,000,000 and
$300,000,000 in assets, was completed. Through this analysis, it was determined
that PTC's allowance to total loans percentage relationship was significantly
less than its peer group. Management will fund the reserve during the fourth
quarter of 1997 to bring PTC closer to its peer group and to recognize the
tremendous growth experienced during the past two years.

    Chargeoffs were $750,000 for 1997, of which $550,000 was related to one loan
relationship. As of September 30, 1997, the carrying value of loans to a
bankrupt commercial borrower was $750,000, which is included in non-accrual
loans. An agreed settlement has been approved through the bankruptcy courts and
payment is expected before year end. No additional loss is expected.
 
CAPITAL
 
    Shareholders' equity increased from $21,653,000 at December 31, 1996 to
$23,740,000 at September 30, 1997. The increase of $2,087,000 was almost solely
due to retained earnings--net income less cash dividends.

LIQUIDITY
 
    Liquidity management involves maintaining sufficient cash levels to fund
operations and to meet the requirements of borrowers, depositors and creditors.
High levels of liquidity bear higher corresponding costs, measured in terms of
lower yields on short-term investments, more liquid earning assets, and higher
interest expense involved in extending liability maturities. Liquid assets
include cash and cash equivalents, loans and securities maturing within one
year, and money market instruments. In addition, PTC holds $20,972,000 of AFS
securities maturing after one year which can be sold to meet liquidity needs.
 
    Liquidity is supported by maintaining a relatively stable funding base,
which is achieved by diversifying funding sources, extending the contractual
maturity of liabilities, and limiting reliance on volatile short-term purchased
funds. Short-term funding needs may arise from declines in deposits or other
funding sources, draw downs of loan commitments and requests for new loans.
PTC's strategy is to fund assets to the maximum extent possible with core
deposits, which provide a sizable source of relatively stable and low-cost
funds. Average core deposits funded approximately 87% of total earning assets at
September 30, 1997.
 
    Management believes PTC has sufficient liquidity to meet all reasonable
borrower, depositor, and creditor needs in the present economic environment. PTC
has not received any recommendations from regulatory authorities, which would
materially affect liquidity, capital resources or operations.
 
INTEREST RATE RISK
 
    At September 30, 1997, PTC held approximately $178,606,000 in assets
comprised of securities, loans, short-term investments, and federal funds sold,
which were interest sensitive in one year or less time horizons. PTC's interest
rate sensitivity analysis at September 30, 1997 appears below. Core deposits are
distributed or spread among the various repricing categories based upon
historical patterns of repricing which are reviewed periodically by management.
The assumptions regarding these repricing characteristics greatly influence
conclusions regarding interest sensitivity. Management believes its assumptions
regarding these liabilities are reasonable.
 
    Effective asset/liability management requires the maintenance of a proper
ratio between maturing or repriceable interest-earning assets and
interest-bearing liabilities. It is the policy of PTC that rate-sensitive
 
                                       56
<PAGE>
assets less rate-sensitive liabilities to total assets are kept within a range
of 85% to 115% for all time periods one year and longer.

EFFECTS OF CHANGING PRICES
 
    PTC's asset and liability structure is substantially different from that of
an industrial company in that most of its assets and liabilities are monetary in
nature. Management believes the impact of inflation on financial results depends
upon PTC's ability to react to changes in interest rates and, by such reaction,
reduce the inflationary impact on performance. Interest rates do not necessarily
move in the same direction at the same time, or at the same magnitude, as the
prices of other goods and services, As discussed previously, management relies
on its ability to manage the relationship between interest-sensitive asset and
liabilities to protect against wide interest rate fluctuations, including those
resulting from inflation.
 
FACILITIES AND TECHNOLOGY
 
    In an effort to make its service more accessible and convenient, PTC is
considering renovating its main banking facility in Rushville. This renovation
will enhance customer accessibility to the bank's various products and services
as well as enhance drive-through banking, ATM accessibility and customer
parking.
 
    During 1997, PTC initiated many technological improvements. Certain of these
improvements represent capital investments, which allows PTC to continue to
efficiently compete within the financial services industry which is becoming
increasingly dependent upon technology. Investments are being made in additional
ATM's, cash dispensers, Automated Voice Response System, debit cards, and
additional state-of-the-art personal computers which will allow for improved
efficiencies in customer service.
 
YEAR ENDED DECEMBER 31, 1995 AND 1996
 
    The following discussion and analysis provides information regarding PTC's
consolidated financial condition and results of operations as of and for the
years ended December 31, 1995 and 1996.
 
EARNINGS SUMMARY
 
    PTC's net income for 1996 was $3,276,000 compared with net income for 1995
of $2,907,000, an increase of $369,000 or 12.7%. Earnings per share were $3.17
in 1996 compared to $2.86 for 1995.
 
NET INTEREST INCOME
 
    Net interest income is the principal component of net income for PTC and is
determined by the relative size and characteristics of interest-earning assets
and interest-bearing liabilities. The increase in net income in 1996 resulted
primarily from an increase in net interest income. For the years ended December
31, 1996 and 1995 net interest income was $10,422,000 and $9,585,000,
respectively. This represents an increase in 1996 of $840,000 (8.03%).
 
                                       57
<PAGE>
    Growth in net interest income is drawn primarily from growth in earning
assets. Average earning assets increased to $257,011,000 in 1996 from
$234,731,000 in 1995, an increase of $22,280,000 (9.5%). The most significant
increase in average earning assets occurred in average loans which increased
$16,943,000 (10.1%) to $184,447,000 in 1996. Increasing loan balances were the
primary cause of the increase in net interest income during 1996. The following
table sets forth, for the periods indicated, information regarding the average
balances of interest-earning assets and interest-bearing liabilities, the dollar
amount of interest income and interest expense, and the resulting yield on
average interest-earning assets and rates on average interest-bearing
liabilities. Average balances are also provided for non-earning assets, non-
interest-bearing liabilities and shareholders' equity.
 
    Net interest income also depends on the rates paid on assets and the rates
paid on liabilities. The net interest margin represents net interest income as a
percent of average earning assets. The net interest margin, or margin on earning
assets, was 4.39% in 1996 and 4.37% in 1995. Interest rates were low and stable
during this time period and the result has been about the same margins.

(1) Effective tax rates were determined as though interest earned on PTC's
    investments in municipal bonds and loans was fully taxable. Interest yields
    on state and municipal securities are presented on a fully taxable
    equivalent basis using a 34% tax rate.
 
(2) Interest income on loans included fees of $437,000 and $370,000 for 1996 and
    1995.
 
(3) Non-accrual loans are included in average balance.
 
    The following table presents information regarding PTC's interest income and
interest expense for the periods indicated. The table presents the amount of
change in interest income or interest expense which is attributable to the
change in the average balance (volume) and the amount of change which is related
to change in rates. The net change, attributable to the combined impact of
volume and rate, has been allocated proportionately to the change due to volume
and the change due to rate. Increases in balances

were responsible for an increase in net interest income of $1,058,000 during
1996, however, this was offset by a decrease in spread of $46,000 resulting in a
$1,012,000 increase in net interest income.

NON-INTEREST INCOME
 
    Total non-interest income was $2,349,000 in 1996 and $1,902,000 in 1995.
This reflected an increase in 1996 of $447,000 (23.5%). Service charges on
deposit accounts were relatively flat in 1996 compared to 1995. The amounts were
$1,199,000 in 1996 compared to $1,192,000 in 1995.
 
    Mortgage banking revenues included net gains and losses realized when
mortgage loans were sold into the secondary market, service fee revenue earned
from servicing those loans after they were sold and points paid by customers at
time of closing. Mortgage banking revenue, as reflected in PTC's financial
statements, has not been reduced by the associated costs, such as compensation
expense, which is shown elsewhere within non-interest expense. Total mortgage
banking revenue was $795,000 in 1996 and $447,000 in 1995. This reflects an
increase in 1996 of $348,000 (78%). The majority of this increase is from PTC
adopting SFAS No. 122 which recognizes the income value of servicing rights.
This accounting change increased income in mortgage banking $225,000 in 1996.
 
    People's Trust sold its travel agency in April, 1996 so it could concentrate
its focus on additional banking facilities, products and services. As a result,
travel commission revenues decreased from $178,000 in 1995 to $66,000 in 1996
(62.8%). PTC does not engage in the purchase and sale of securities with the
intent to generate gains. PTC may sell available-for-sale securities for
liquidity or to manage its asset/ liability position. During 1996, such sales,
as well as gains and losses realized when securities were called prior to their
maturity, generated net gains of $104,000 compared to losses in 1995 of $76,000.

NON-INTEREST EXPENSE
 
    Non-interest expense, or overhead, includes the costs of personnel,
occupancy, data processing equipment, insurance, and other costs of sustaining
operations. Overhead for the years ended December 31, 1996 and 1995 was
$7,103,000 and $6,639,000, respectively. This reflects increases of $464,000
(7%) in 1996. More than half of total non-interest expense was comprised of
salaries and employee benefits. During 1996 and 1995 salaries and employee
benefits were $4,137,000 and $3,725,000 respectively. This represents an 11%
increase which was due to People's Trust opening and staffing two new branches
during 1996. The new branches are expected to have a positive effect on net
income by the beginning of 1998.
 
    FDIC insurance expense decreased $249,000 in 1996 as a result of a decrease
in the premium rates charged to insured banks. Other operating expenses
increased $208,000 from 1995 to 1996 for a variety of reasons, including higher
advertising and promotional expenses, legal and professional fees, and charge
card expenses.
 
INCOME TAXES
 
    PTC's income tax expense was affected primarily by the level of pre-tax
income. As income increased, tax expense did as well. Tax expense for 1996
increased $364,000 over 1995. PTC can and does purchase tax-free investments and
originates tax-free loans as a means of generating tax-free income, effectively
mitigating tax expense.
 
ASSET AND LIABILITY MANAGEMENT
 
    PTC engages in a formal process of measuring and defining the amount of
interest rate risk. Interest rate risk is the effect on net interest income
resulting from changes in interest rates. The goal of the asset and liability
management process is to maintain a high, yet stable, net interest margin by
identifying the degree of interest rate risk and developing tactics and
strategies to mitigate the extent to which net interest income will be affected
by changes in interest rates.
 
    The following table illustrates the repricing opportunities, or "rate
sensitivity" of interest-earning assets and interest bearing liabilities. A
repricing may occur if the rate on the asset or liability changes as interest
rates change, or, when the rate is fixed, at the time they mature. The "gap" is
the difference between rate sensitive assets and rate sensitive liabilities
within a specific time frame. Gap is considered an indicator of the effect a
change in interest may have on net interest income.
 
    As of December 31, 1996, PTC's rate-sensitive liabilities exceeded
rate-sensitive assets through one year. This would indicate that if rates
increase, net interest income may decrease. In order to determine accurately the
effect of changes in interest rates, the repricing effect of each type of
interest-earning asset and interest-bearing liability must be measured. Assets
and liabilities have different characteristics and the magnitude of change
differs for each. Management continually monitors the changes to net interest
income which may result from changing interest rates.

    A significant assumption that creates the large negative gap in the 0 to 3
month category is that all interest-bearing demand accounts are subject to
immediate repricing. While it is true that contractually, those accounts are
subject to immediate repricing, the rates paid on those accounts are not
generally tied to specific indices and are influenced by market conditions and
other factors. Accordingly, a general movement in interest rates, either up or
down, may not have any immediate effect on the rates paid on these deposit
accounts. The foregoing table illustrates only one source of information about
sensitivity to interest rate movements. The core of PTC's asset and liability
management process consists of simulations that take into account the time that
various assets and liabilities may reprice and the degree to which various
categories of such assets and liabilities will respond to general interest rate
movements. Interest rate risk can only be represented by a measurement of the
effects of changing interest rates given the capacity for, and magnitude of,
change of specific assets and liabilities.
 
LIQUIDITY
 
    Liquidity refers to the availability of funds to meet deposit withdrawals,
fund loan commitments and pay expenses. During 1996, PTC's loan portfolio
increased to $197,000,000 at December 31, 1996 from $173,000,000 at December 31,
1995, an increase of $24,000,000 or 13.7%. Increases in deposits provided one
source of funding for loan growth in 1996. Average interest-bearing deposits
increased $21,000 (10%) between 1995 and 1996. Additional funding for loan
growth was provided through sales and maturities of securities.
 
                                       62
<PAGE>
    A common measure of liquidity is the loan to deposit ratio. As of December
31, PTC had a loan to deposit ratio of 72.6% in 1996, and 71.7% in 1995.
Increasing this ratio was an important goal for PTC's management during 1996,
and significantly added to PTC's profitability.
 
    Loan commitments include unfunded portions of lines of credit and commercial
letters of credit. These unfunded commitments may or may not require funding. At
December 31, 1996 and 1995, such commitments totaled $30,000,000 and
$18,000,000, respectively. Loan commitments generate fee income for PTC.
 
LOAN QUALITY
 
    PTC has maintained a high level of quality in the loan portfolio.
Non-performing loans are those loans which are past due more than 90 days and
still accruing interest and those loans on which PTC no longer accrues interest.
As of December 31, 1996 and 1995, non-performing loans totaled $1,828,000 and
$1,464,000, respectively. As a percent of total loans, non-performing loans were
0.93% at December 31, 1996 and 0.84% at December 31, 1995.
 
    The provision for loan losses is a charge to earnings to provide for
potential loan losses. The provision for loan losses was $828,000 in 1996 and
$740,000 in 1995. Coverage of potential loan losses is provided by the allowance
for loan losses. The adequacy of the allowance for loan losses is evaluated at
least quarterly by the credit review function and management based upon a review
of identified loans with more than a normal degree of risk, historical loss
percentages, and present and forecasted economic conditions affecting borrowers.
At December 31, the allowance for loan losses was $2,000,000 for 1996 and
$1,722,000 for 1995. As a percent of total loans, the allowance for loan losses
was 1.02% and 0.99% at those points in time. Management's analysis indicates
that the allowance for loan losses at December 31, 1996, was adequate to cover
potential losses on identified loans with credit problems and on the remaining
portfolio. Contained within the general allowance for loan loss specific
allocations can be made if management can determine a loss. In the case of loans
to a bankrupt commercial borrower, management had specifically reserved
$475,000.
 
    Gross loan chargeoffs in 1996 and 1995 were $726,000 and $855,000,
respectively. As a percentage of average loans, gross loan chargeoffs were 0.39%
and 0.51% for those periods.
 
    Effective January 1, 1995, PTC was required to adopt SFAS No. 114 which
required recognition of loan impairment. Loans are considered impaired if full
principal or interest payments are not anticipated. Impaired loans are carried
at the present value of expected cash flows discounted at the loan's effective
interest rate or at the fair value of the collateral if the loan is collateral
dependent. A portion of the allowance for loan losses is allocated to impaired
loans. PTC's average investment in impaired loans during 1996 was $844,000. At
December 31, 1996, $1,300,000 of loans were deemed to be impaired and $475,000
of the allowance for loan losses was allocated to those loans. At December 31,
1995, impaired loans were $129,000. The large increase in impaired loans was
related to loans to Bennett Funding.
 
CAPITAL
 
    In June, 1994, PTC completed a rights offering of its common shares at
$25.00 per share ($15.50 per share when adjusted for a subsequent stock split
and stock dividend). The net proceeds after commissions and expenses from the
sale of 60,000 shares were approximately $1,480,000. This rights offering
included options which were exercised in January 1996, resulting in the issuance
of 28,449 shares for a total of $485,000 at $17.05 per share ($15.50 when
adjusted for a subsequent stock dividend). In April, 1996, PTC repurchased
22,632 shares at a market price of $30 per share ($27.27 when adjusted for a
subsequent stock dividend).
 
    Both PTC and People's Trust are required to comply with capital requirements
promulgated by their primary regulators. Those regulations require the
maintenance of specified levels of capital to total assets
 
                                       63
<PAGE>
(the leverage ratio) and to risk-weighted assets (the risk-based capital ratio).
These regulations require maintaining a leverage ratio of at least 5% for
"well-capitalized" entities and a total risk-based capital ratio of at least
10%.
 
    PTC and People's Trust were in full compliance with all regulatory capital
requirements at December 31, 1996. The following table indicates PTC's actual
capital levels at the dates indicated.

NEW ACCOUNTING PRONOUNCEMENTS
 
    SFAS No. 125 was issued by the FASB in 1996. It revises the accounting for
transfers of financial assets, such as loans and securities, and for
distinguishing between sales and secured borrowings. It is effective for some
transactions in 1997 and others in 1998. The effect on the financial statements
of PTC and People's Trust is not expected to be material.

                            BUSINESS OF THE COMPANY
 
GENERAL
 
    The Company was initially formed in Owensboro, Kentucky in 1982 as First
Commonwealth Bancorp. The Company reincorporated under the laws of the State of
Indiana under its present name in 1983, and relocated to Greensburg, Indiana in
anticipation of acquiring Union Bank. In 1987, The Peoples Bank, in Portland,
Indiana ("Peoples Bank"), was acquired and as of December 31, 1991, Regional
Bank was acquired. Effective July 1, 1994, the Company merged Union Bank with
Peoples Bank, with the resulting bank renamed Union Bank and Trust Company of
Indiana ("Union Bank"). Through Union Bank and Regional Bank, the Company
operates twelve offices with 143 full-time equivalent employees in eastern and
southern Indiana. As of September 30, 1997, the Company had consolidated assets
of $342 million, consolidated deposits of $286 million and shareholders' equity
of $30 million.
 
    Through its subsidiaries, the Company offers a broad range of financial
services, including: accepting time and transaction deposits; making consumer,
commercial, agri-business and real estate mortgage loans; issuing credit cards;
renting safe deposit facilities; providing general agency personal and business
insurance services; providing personal and corporate trust services; and
providing other corporate services such as payroll processing, letters of credit
and repurchase agreements.
 
    The Company's subsidiaries are located in non-metropolitan areas and their
business is centered in loans and deposits generated within markets considered
to be largely rural in nature. In addition to competing with other banks, thrift
institutions, credit unions and finance companies located within their service
areas, they also compete, directly and indirectly, with all providers of
financial services.
 
RECENT DEVELOPMENTS
 
    The Company is a party to an Agreement and Plan of Merger with PTC dated as
of October 8, 1997 (the "Merger Agreement") pursuant to which PTC would merge
with and into the Company and People's Trust would become a wholly owned
subsidiary of the Company, and each outstanding share of PTC at the effective
time of the merger would be converted into the right to receive 1.075 shares of
common stock of the Company (the "PTC Merger"). The Company expects to issue in
the aggregate up to 1,136,417 shares of common stock in the PTC Merger. The PTC
Merger is expected to be completed late in the fourth quarter of 1997 or early
in the first quarter of 1998.
 
    At September 30, 1997, PTC had total assets of $302.7 million, total
deposits of $275.7 million and total shareholders' equity of $23.7 million. PTC
had net income of $2.7 million for the nine months ended September 30, 1997,
compared to net income of $2.4 million for the nine months ended September 30,
1996. See "PTC Selected Financial Data" and "PTC Management's Discussion and
Analysis of Financial Condition and Results of Operations." People's Trust
engages in a general full-service commercial and consumer banking business.
People's Trust conducts its banking business through 17 offices located in the
Indiana counties of Dearborn, Franklin, Jefferson, Ripley, Rush, Fayette,
Decatur, Switzerland and Wayne.
 
    PTC is subject to the informational reporting requirements of the Exchange
Act. Information about PTC may be obtained from the Public Reference Section of
the Commission or accessed through electronic means, including the Commission's
home page on the Internet (http://www.sec.gov), in the same manner that
information about the Company may be obtained. See "Available Information."
 
    The PTC Merger is expected to qualify as a "pooling of interests" for
accounting and financial reporting purposes. See "Summary of Pro Forma
Consolidated Financial Data," "Pro Forma Selected Financial Data" and "Index to
Consolidated Financial Statements and Pro Forma Consolidated Financial
Statements." The PTC Merger is intended to be a tax free reorganization so that
no gain or loss would be recognized by the Company or PTC, and no gain or loss
would be recognized by shareholders of PTC except in respect of cash received
for fractional shares or pursuant to the exercise of statutory dissenters'
rights. The PTC Merger is subject to various conditions, including requisite
shareholder and regulatory approvals. Accordingly, no assurance can be given
that the PTC Merger will be consummated. If the PTC
 
                                       65
<PAGE>
Merger is not consummated, the anticipated significant increase in the Company's
capital base due to the PTC Merger will not be realized. Consequently, due to
regulatory capital requirements, the Company's ability to utilize a portion of
the offering proceeds for future acquisitions and other growth would be
adversely affected if the PTC Merger is not consummated.
 
    Following the PTC Merger, pursuant to the Merger Agreement, the Board of
Directors of the Company will consist of ten members, five of which will have
been designated by the Company and five of which will have been designated by
PTC. The Merger Agreement also provides that the Company's Chairman of the
Board, President and Chief Executive Officer, Robert E. Hoptry, will continue to
be the Company's Chairman of the Board and Chief Executive Officer and that
PTC's President and Chief Executive Officer, James L. Saner, will be President
and Chief Operating Officer of the Company following the PTC Merger.
 
EMPLOYEES
 
    As of September 30, 1997, the Company and its subsidiaries had approximately
151 full-time equivalent employees to whom it provides a variety of benefits.
Management believes that its relationship with its employees is good.
 
REGULATION AND SUPERVISION OF THE COMPANY
 
    The Company is a bank holding company ("BHC") within the meaning of the Bank
Holding Company Act of 1956, as amended ("BHCA"). This Act subjects BHCs to
regulations of the Federal Reserve and restricts the business of BHCs to banking
and related activities. In addition, the Company is a nondiversified unitary
savings and loan holding company subject to regulations, examinations,
supervision and reporting requirements of the Office of Thrift Supervision
("OTS").
 
    Under the BHCA, a BHC is, with limited exceptions, prohibited from acquiring
direct or indirect ownership or control of voting stock of any company which is
not a bank or engaging in any activity other than managing or controlling banks.
A BHC may, however, own shares of a company engaged in activities which the
Federal Reserve has determined to be so closely related to banking or managing
or controlling banks as to be a proper incident thereto.
 
    Acquisitions by the Company of banks and savings associations are subject to
federal and state regulation. Any acquisition by the Company of more than five
percent of the voting stock of any bank requires prior approval of the Federal
Reserve. Acquisition of savings associations is also subject to the approval of
the OTS.
 
    Indiana law permits BHCs to acquire BHCs and banks out of state on a
reciprocal basis, subject to certain limitations. Under current law, the Company
may acquire banks, and may be acquired by BHCs, located in any state in the
United States which permits reciprocal entry by Indiana BHCs. Under the BHCA,
BHCs may acquire savings associations without geographic restrictions.
 
    A BHC and its subsidiaries are prohibited from engaging in certain tying
arrangements in connection with the extension of credit, lease or sale of
property, or the provision of any property or service.
 
    The Company is under the jurisdiction of the Commission and state securities
commission for matters relating to the offering and sale of its securities. The
Company is subject to the Commission's rules and regulations relating to
periodic reporting, reporting to shareholders, proxy solicitation and insider
trading. See "Available Information."
 
    The Company's income is principally derived from dividends paid on the
common stock of its subsidiaries. The payment of these dividends is subject to
certain regulatory restrictions.
 
    Under Federal Reserve policy, the Company is expected to act as a source of
financial strength to, and commit resources to support, its affiliates. As a
result of such policy, the Company may be required to commit resources to its
affiliate banks in circumstances where it might not otherwise do so.
 
                                       66
<PAGE>
REGULATION AND SUPERVISION OF THE SUBSIDIARY BANKS
 
    Union Bank is supervised, regulated and examined by the Indiana Department
of Financial Institutions ("DFI") and the FDIC. Regional Bank is supervised,
regulated and examined by the OTS. A cease-and-desist order may be issued
against the banks, if the respective agency finds that the activities of the
bank represents an unsafe and unsound banking practice or violation of law.
 
    The deposits of Union Bank are insured by the BIF of the FDIC. The deposits
of Regional Bank are insured by the SAIF of the FDIC. The FDIC has the authority
to change premiums twice per year. Commencing in 1997 and until 1999, thrift
institutions will pay approximately five times higher assessment rates than
commercial banks (6.44 cents versus 1.29 cents per $100 of deposits). After the
three year period, BIF and SAIF-insured institutions will pay the same
assessment rate of 2.43 cents per $100 of deposits. Based on 1996 year end
deposit levels, Union Bank's deposit insurance expense will increase
approximately $22,000 and Regional Bank will save approximately $155,000
compared to the assessment rates paid in 1996 as a result of these changes.
 
    Branching by banks in Indiana is subject to the jurisdiction, and requires
the prior approval, of the bank's or savings bank's primary federal regulatory
authority and, if the branching bank is a state bank, of the DFI. Under Indiana
law, the banks may branch anywhere in the state.
 
    The Company is a legal entity separate and distinct from its subsidiary
Banks. There are various legal limitations on the extent to which the Banks can
supply funds to the Company. The principal source of the Company's funds
consists of dividends from its subsidiary Banks. State and Federal law restrict
the amount of dividends which may be paid by banks and savings banks. In
addition, the Banks are subject to certain restrictions on extensions of credit
to the Company, on investments in the stock or other securities of the Company
and in taking such stock or securities as collateral for loans.
 
LEGISLATION
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
represented a comprehensive and fundamental change to banking supervision and
mandates the development of additional regulations governing almost every aspect
of the operations, management and supervision of banks and BHCs.
 
    FDICIA also included several supervisory reforms related to the frequency of
regulatory examinations and audit requirements. FDICIA also required the
adoption of safety and soundness standards on matters such as loan underwriting
and documentation, and compensation and other employee benefits; mandated
consumer protection disclosures with respect to deposit accounts; and the
establishment of a risk-based deposit insurance system. To date, many of the
provisions of FDICIA have been implemented.
 
    FDICIA requires banking regulators to take prompt corrective actions with
respect to depository institutions that fall below certain capital levels and
prohibit any depository institution from making a capital distribution that
would cause it to be considered undercapitalized. Banking regulators were also
required to revise their capital standards to take into account interest rate
risk. A policy statement has been proposed providing a supervisory framework to
measure and monitor interest rate risk at individual banks. Banks may use an
internal model which provides a measure of the change in a bank's economic
value. The results of the supervisory and internal models would be one factor
regulators will consider in their assessment of capital adequacy. Other factors
will also be considered.
 
    Certain regulations define relevant capital measures for five capital
categories. A "well capitalized" institution is one that has a total risk-based
capital ratio of at least 10%, a Tier 1 risk-based capital ratio of at least 8%,
a leverage ratio of at least 5% and is not subject to regulatory direction to
maintain a specific level for any capital measure. An "adequately capitalized"
institution is one that has ratios greater than 8%, 4% and 4%. An institution is
"undercapitalized" if its respective ratios are less than 8%, 4% and 4%.
"Significantly undercapitalized" institutions have ratios of less than 6%, 3%
and 3%. An institution is deemed to be "critically undercapitalized" if it has a
ratio of tangible equity to total assets that is 2% or
 
                                       67
<PAGE>
less. Institutions with capital ratios at levels of "undercapitalized" or lower
are subject to various limitations which, in most situations, will reduce the
competitiveness of the institution.
 
    The Riegle Community Development and Regulatory Improvement Act of 1994
("Riegle Act") was signed into law in 1994. The Riegle Act contains seven titles
pertaining to community development and home ownership protection, small
business capital formation, paperwork reduction and regulatory improvement,
money laundering and flood insurance.
 
    In September 1994, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 ("Branching Act") was enacted. In general, the Branching
Act permits BHCs that are adequately capitalized and adequately managed to
acquire banks located in any other state, subject to certain total deposit
limitations. The Branching Act also permits full interstate branching. States,
however, may have elected to prohibit interstate branching and merger
transactions by enacting legislation prior to June 1, 1997 that applies equally
to all out-of-state banks and expressly prohibits mergers involving out-of-state
banks. Indiana did not enact such legislation.
 
    The monetary policies of regulatory authorities have a significant effect of
the operating results of banks and BHCs. The nature of future monetary policies
and the effect of such policies on the future business and earnings of the
Company and its subsidiaries cannot be predicted.
 
    The Deposit Insurance Funds Act was enacted in 1996 and contained several
major provisions. The new law recapitalized the SAIF by a one-time assessment on
all SAIF-insured deposits. For 1997 through 1999 the banking industry will help
pay for the Financing Corp. ("FICO") bond interest payments at an assessment
rate that is one-fifth the rate paid by thrifts. Beginning January 1, 2000, the
FICO interest payments will be paid pro-rata by banks and thrifts. Deposit
shifting is prohibited for three years and the $2,000 annual minimum deposit
insurance assessment was repealed. The BIF and SAIF will be merged on January 1,
1999 providing a law is passed by that date merging the bank and thrift
charters. In addition, there were more than forty regulatory relief provisions
in this bill.
 
CAPITAL REQUIREMENTS
 
    The Company and its subsidiary Banks must meet certain minimum capital
requirements mandated by the Federal Reserve, FDIC, OTS and DFI. These
regulatory agencies require BHCs and banks to maintain certain minimum ratios of
primary capital to total assets and total capital to total assets. The Federal
Reserve requires BHCs to maintain a minimum Tier 1 leverage ratio of 3% capital
to total assets; however, for all but the most highly rated institutions which
do not anticipate significant growth, the minimum Tier 1 leverage ratio is 3%
plus an additional cushion of 100 to 200 basis points. As of September 30, 1997,
the Company's leverage ratio of capital to total assets was 8.58%.
 
    The Federal Reserve, OTS and FDIC each have approved the imposition of
"risk-adjusted" capital ratios on BHCs and financial institutions. The Company
and its subsidiaries had capital to assets ratios and risk-adjusted capital
ratios at September 30, 1997, in excess of the applicable regulatory minimum
requirements.
 
YEAR 2000 COMPUTER ISSUES
 
    In the next two years, most large companies will face a potentially serious
information systems (computer) problem because many software application and
operational programs written in the past may not properly recognize calendar
dates beginning in the year 2000. This problem could force computers to either
shut down or provide incorrect data or information. The Company began the
process of identifying the changes required to its computer programs and
hardware, in consultation with software and hardware providers and bank
regulators, in early 1997. While the Company believes it is taking all
appropriate steps to assure year 2000 compliance, it is dependent on vendor
compliance to some extent. The Company is requiring its systems and software
vendors to represent that the services and products provided are, or will be,
year 2000 compliant, and contemplates a program of testing compliance. The
Company estimates that
 
                                       68
<PAGE>
its costs related to year 2000 compliance will be at least $50,000 and may be
significantly more. The "year 2000" problem is persuasive and complex as
virtually every computer operation will be affected in some way by the rollover
of the two digit year value to 00. Consequently, no assurance can be given that
year 2000 compliance can be achieved without costs and uncertainties that might
affect future financial results or cause reported financial information not to
be necessarily indicative of future operating results or future financial
condition.
 
                    DESCRIPTION OF THE PREFERRED SECURITIES
 
    The Preferred Securities will be issued pursuant to the terms of the Trust
Agreement. The Trust Agreement will be qualified as an indenture under the Trust
Indenture Act. The Property Trustee, State Street Bank and Trust Company, will
act as indenture trustee for the Preferred Securities under the Trust Agreement
for purposes of complying with the provisions of the Trust Indenture Act. The
terms of the Preferred Securities will include those stated in the Trust
Agreement and those made part of the Trust Agreement by the Trust Indenture Act.
The following summary of the material terms and provisions of the Preferred
Securities and the Trust Agreement does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, the Trust
Agreement, the Trust Act, and the Trust Indenture Act. Wherever particular
defined terms of the Trust Agreement are referred to, but not defined herein,
such defined terms are incorporated herein by reference. The form of the Trust
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part.
 
GENERAL
 
    Pursuant to the terms of the Trust Agreement, the Trustees, on behalf of IUB
Trust, will issue the Trust Securities. All of the Common Securities will be
owned by the Company. The Preferred Securities will represent preferred
undivided beneficial interests in the assets of IUB Trust and the holders
thereof will be entitled to a preference in certain circumstances with respect
to Distributions and amounts payable on redemption or liquidation over the
Common Securities, as well as other benefits as described in the Trust
Agreement. The Trust Agreement does not permit the issuance by IUB Trust of any
securities other than the Trust Securities or the incurrence of any indebtedness
by IUB Trust.
 
    The Preferred Securities will rank PARI PASSU, and payments will be made
thereon pro rata, with the Common Securities, except as described under
"--Subordination of the Common Securities." Legal title to the Subordinated
Debentures will be held by the Property Trustee in trust for the benefit of the
holders of the Trust Securities. The Guarantee executed by the Company for the
benefit of the holders of the Preferred Securities will be a guarantee on a
subordinated basis with respect to the Preferred Securities, but will not
guarantee payment of Distributions or amounts payable on redemption or
liquidation of such Preferred Securities when IUB Trust does not have funds on
hand available to make such payments. State Street Bank and Trust Company, as
Guarantee Trustee, will hold the Guarantee for the benefit of the holders of the
Preferred Securities. See "Description of the Guarantee."
 
DISTRIBUTIONS
 
    PAYMENT OF DISTRIBUTIONS.  Distributions on each Preferred Security will be
payable at the annual rate of       % of the stated Liquidation Amount of $10,
payable quarterly in arrears on March 31, June 30, September 30 and December 31
of each year, to the holders of the Preferred Securities on the relevant record
dates (each date on which Distributions are payable in accordance with the
foregoing, a "Distribution Date"). The record date will be the 15th day of the
month in which the relevant Distribution Date occurs. Distributions will
accumulate from       , 1997, the date of original issuance. The first
Distribution Date for the Preferred Securities will be December 31, 1997. The
amount of Distributions payable for any period will be computed on the basis of
a 360-day year of twelve 30-day months. In the event that any date on which
Distributions are payable on the Preferred 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 additional Distributions,
interest or other payment in respect of any such delay) with the same
 
                                       69
<PAGE>
force and effect as if made on the date such payment was originally due and
payable. "Business Day" means any day other than a Saturday or a Sunday or a day
on which Federal or state banking institutions in the Borough of Manhattan, the
City of New York, are authorized or required by law, executive order or
regulation to close, or a day on which the corporate trust office of the
Property Trustee or the corporate trust office of the Debenture Trustee is
closed for business.
 
    EXTENSION PERIOD.  The Company has the right under the Indenture, so long as
no Debenture Event of Default has occurred and is continuing, to defer the
payment of interest on the Subordinated Debentures at any time, or from time to
time (each, an "Extension Period"), which, if exercised, would defer quarterly
Distributions on the Preferred Securities during any such Extension Period.
Distributions to which the holders of the Preferred Securities are entitled will
accumulate additional Distributions thereon at the rate per annum of       %
thereof, compounded quarterly from the relevant Distribution Date.
"Distributions," as used herein, includes any such additional Distributions. The
right to defer the payment of interest on the Subordinated Debentures is
limited, however, to a period, in each instance, not exceeding 20 consecutive
quarters and no Extension Period may extend beyond the Stated Maturity of the
Subordinated Debentures. During any such Extension Period, the Company may 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 Company's
capital stock, (ii) make any payment of principal, interest or premium, if any,
on or repay, repurchase or redeem any debt securities of the Company that rank
PARI PASSU with or junior in interest to the Subordinated Debentures or make any
guarantee payments with respect to any guarantee by the Company of the debt
securities of any subsidiary of the Company if such guarantee ranks PARI PASSU
with or junior in interest to the Subordinated Debentures (other than payments
under the Guarantee), or (iii) redeem, purchase or acquire less than all of the
Subordinated Debentures or any of the Preferred Securities. Prior to the
termination of any such Extension Period, the Company may further defer the
payment of interest; provided that such Extension Period may not exceed 20
consecutive quarters or extend beyond the Stated Maturity of the Subordinated
Debentures. Upon the termination of any such Extension Period and the payment of
all amounts then due, the Company may elect to begin a new Extension Period,
subject to the above requirements. Subject to the foregoing, there is no
limitation on the number of times that the Company may elect to begin an
Extension Period.
 
    The Company has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the
Subordinated Debentures.
 
    SOURCE OF DISTRIBUTIONS.  The funds of IUB Trust available for distribution
to holders of its Preferred Securities will be limited to payments under the
Subordinated Debentures in which IUB Trust will invest the proceeds from the
issuance and sale of its Trust Securities. See "Description of the Subordinated
Debentures." Distributions will be paid through the Property Trustee who will
hold amounts received in respect of the Subordinated Debentures in the Property
Account for the benefit of the holders of the Trust Securities. If the Company
does not make interest payments on the Subordinated Debentures, the Property
Trustee will not have funds available to pay Distributions on the Preferred
Securities. The payment of Distributions (if and to the extent IUB Trust has
funds legally available for the payment of such Distributions and cash
sufficient to make such payments) is guaranteed by the Company. See "Description
of the Guarantee." Distributions on the Preferred Securities will be payable to
the holders thereof as they appear on the register of holders of the Preferred
Securities on the relevant record dates, which will be the 15th day of the month
in which the relevant Distribution Date occurs.
 
REDEMPTION
 
    GENERAL.  The Subordinated Debentures will mature on December 31, 2027. The
Company will have the right to redeem the Subordinated Debentures (i) on or
after December 31, 2002, in whole at any time or in part from time to time, or
(ii) at any time, in whole (but not in part), within 180 days following the
occurrence of a Tax Event, a Capital Treatment Event or an Investment Company
Event, in each case subject to receipt of prior approval by the Federal Reserve
if then required under applicable capital
 
                                       70
<PAGE>
guidelines or policies of the Federal Reserve. The Company will not have the
right to purchase the Subordinated Debentures, in whole or in part, from IUB
Trust until after December 31, 2002. See "Description of the Subordinated
Debentures--General."
 
    MANDATORY REDEMPTION.  Upon the repayment or redemption, in whole or in
part, of any Subordinated Debentures, whether at Stated Maturity or upon earlier
redemption as provided in the Indenture, the proceeds from such repayment or
redemption will be applied by the Property Trustee to redeem a Like Amount (as
defined herein) of the Trust Securities, upon not less than 30 nor more than 60
days notice, at a redemption price (the "Redemption Price") equal to the
aggregate Liquidation Amount of such Trust Securities plus accumulated but
unpaid Distributions thereon to the date of redemption (the "Redemption Date").
See "Description of the Subordinated Debentures--Redemption or Exchange." If
less than all of the Subordinated Debentures are to be repaid or redeemed on a
Redemption Date, then the proceeds from such repayment or redemption will be
allocated to the redemption of the Trust Securities pro rata.
 
    DISTRIBUTION OF SUBORDINATED DEBENTURES.  Subject to the Company having
received prior approval of the Federal Reserve if so required under applicable
capital guidelines or policies of the Federal Reserve, the Company will have the
right at any time to dissolve, wind-up or terminate IUB Trust and, after
satisfaction of the liabilities of creditors of IUB Trust as provided by
applicable law, cause the Subordinated Debentures to be distributed to the
holders of Trust Securities in liquidation of IUB Trust. See "--Liquidation
Distribution upon Termination."
 
    TAX EVENT REDEMPTION, CAPITAL TREATMENT EVENT REDEMPTION OR INVESTMENT
COMPANY EVENT REDEMPTION.  If a Tax Event, a Capital Treatment Event or an
Investment Company Event in respect of the Trust Securities occurs and is
continuing, the Company has the right to redeem the Subordinated Debentures in
whole (but not in part) and thereby cause a mandatory redemption of such Trust
Securities in whole (but not in part) at the Redemption Price within 180 days
following the occurrence of such Tax Event, Capital Treatment Event or
Investment Company Event. In the event a Tax Event, a Capital Treatment Event or
an Investment Company Event has occurred with respect to the Trust Securities
and the Company does not elect to redeem the Subordinated Debentures and thereby
cause a mandatory redemption of such Trust Securities or to liquidate IUB Trust
and cause the Subordinated Debentures to be distributed to holders of such Trust
Securities in liquidation of IUB Trust as described below under "--Liquidation
Distribution upon Termination," such Preferred Securities will remain
outstanding and Additional Payments (as defined herein) may be payable on the
Subordinated Debentures.
 
    "Additional Payments" means the additional amounts as may be necessary in
order that the amount of Distributions then due and payable by IUB Trust on the
outstanding Trust Securities will not be reduced as a result of any additional
taxes, duties and other governmental charges to which IUB Trust has become
subject as a result of a Tax Event.
 
    "Like Amount" means (i) with respect to a redemption of Trust Securities,
Trust Securities having a Liquidation Amount equal to that portion of the
principal amount of Subordinated Debentures to be contemporaneously redeemed in
accordance with the Indenture, which will be used to pay the Redemption Price of
such Trust Securities, and (ii) with respect to a distribution of Subordinated
Debentures to holders of Trust Securities in connection with a dissolution or
liquidation of IUB Trust, Subordinated Debentures having a principal amount
equal to the Liquidation Amount of the Trust Securities of the holder to whom
such Subordinated Debentures are distributed. Each Subordinated Debenture
distributed pursuant to clause (ii) above will carry with it accumulated
interest in an amount equal to the accumulated and unpaid interest then due on
such Subordinated Debentures.
 
    "Liquidation Amount" means the stated amount of $10 per Trust Security.
 
    After the liquidation date fixed for any distribution of Subordinated
Debentures for Preferred Securities (i) such Preferred Securities will no longer
be deemed to be outstanding, and (ii) any certificates representing Preferred
Securities will be deemed to represent the Subordinated Debentures having a
principal amount equal to the Liquidation Amount of such Preferred Securities,
and bearing accrued and
 
                                       71
<PAGE>
unpaid interest in an amount equal to the accrued and unpaid Distributions on
the Preferred Securities until such certificates are presented to the
Administrative Trustees or their agent for transfer or reissuance.
 
    There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Debentures that may be distributed in exchange
for Preferred Securities if a dissolution and liquidation of IUB Trust were to
occur. The Preferred Securities that an investor may purchase, or the
Subordinated Debentures that an investor may receive on dissolution and
liquidation of IUB Trust, may, therefore, trade at a discount to the price that
the investor paid to purchase the Preferred Securities offered hereby.
 
REDEMPTION PROCEDURES
 
    Preferred Securities redeemed on each Redemption Date will be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Subordinated Debentures. Redemptions of the Preferred
Securities will be made and the Redemption Price will be payable on each
Redemption Date only to the extent that IUB Trust has funds on hand available
for the payment of such Redemption Price. See "--Subordination of the Common
Securities."
 
    If IUB Trust gives a notice of redemption in respect of its Preferred
Securities, then, by 12:00 noon, eastern standard time, on the Redemption Date,
to the extent funds are available, the Property Trustee will irrevocably deposit
with the paying agent for the Preferred Securities funds sufficient to pay the
aggregate Redemption Price and will give the paying agent for the Preferred
Securities irrevocable instructions and authority to pay the Redemption Price to
the holders thereof upon surrender of their certificates evidencing such
Preferred Securities. Notwithstanding the foregoing, Distributions payable on or
prior to the Redemption Date for any Preferred Securities called for redemption
will be payable to the holders of such Preferred Securities on the relevant
record dates for the related Distribution Dates. If notice of redemption will
have been given and funds deposited as required, then upon the date of such
deposit, all rights of the holders of such Preferred Securities so called for
redemption will cease, except the right of the holders of such Preferred
Securities to receive the Redemption Price and any Distribution payable on or
prior to the Redemption Date, but without interest on such Redemption Price, and
such Preferred Securities will cease to be outstanding. In the event that any
date fixed for redemption of Preferred Securities is not a Business Day, then
payment of the Redemption Price payable on such date will be made on the next
succeeding day which is a Business Day (and without any additional Distribution,
interest or other payment in respect of any such delay) with the same force and
effect as if made on such date. In the event that payment of the Redemption
Price in respect of Preferred Securities called for redemption is improperly
withheld or refused and not paid either by IUB Trust, or by the Company pursuant
to the Guarantee, Distributions on such Preferred Securities will continue to
accrue at the then applicable rate, from the Redemption Date originally
established by IUB Trust for such Preferred Securities to the date such
Redemption Price is actually paid, in which case the actual payment date will be
considered the date fixed for redemption for purposes of calculating the
Redemption Price. See "Description of the Guarantee."
 
    Subject to applicable law (including, without limitation, United States
Federal securities law), and further provided that the Company does not and is
not continuing to exercise its right to defer interest payments, the Company or
its subsidiaries may at any time and from time to time purchase outstanding
Preferred Securities by tender, in the open market or by private agreement.
 
    Payment of the Redemption Price on the Preferred Securities and any
distribution of Subordinated Debentures to holders of Preferred Securities will
be made to the applicable holders thereof as they appear on the register for the
Preferred Securities on the relevant record date, which date will be the date 15
days prior to the Redemption Date or liquidation date, as applicable.
 
    If less than all of the Trust Securities are to be redeemed on a Redemption
Date, then the aggregate Liquidation Amount of such Trust Securities to be
redeemed will be allocated pro rata to the Trust Securities based upon the
relative Liquidation Amounts of such classes. The particular Preferred
Securities to be redeemed will be selected by the Property Trustee from the
outstanding Preferred Securities not
 
                                       72
<PAGE>
previously called for redemption, by such method as the Property Trustee deems
fair and appropriate and which may provide for the selection for redemption of
portions (equal to $10 or an integral multiple of $10 in excess thereof) of the
Liquidation Amount of the Preferred Securities of a denomination larger than
$10. The Property Trustee will promptly notify the registrar for the Preferred
Securities in writing of the Preferred Securities selected for redemption and,
in the case of any Preferred Securities selected for partial redemption, the
Liquidation Amount thereof to be redeemed. For all purposes of the Trust
Agreement, unless the context otherwise requires, all provisions relating to the
redemption of the Preferred Securities will relate to the portion of the
aggregate Liquidation Amount of the Preferred Securities which has been or is to
be redeemed.
 
    Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Trust Securities to be
redeemed at its registered address. Unless the Company defaults in payment of
the redemption price on the Subordinated Debentures, on and after the Redemption
Date interest will cease to accrue on such Subordinated Debentures or portions
thereof (and Distributions will cease to accrue on the related Preferred
Securities or portions thereof) called for redemption.
 
SUBORDINATION OF THE COMMON SECURITIES
 
    Payment of Distributions on, and the Redemption Price of, the Preferred
Securities and Common Securities, as applicable, will be made pro rata based on
the Liquidation Amount of the Preferred Securities and Common Securities;
provided, however, that if on any Distribution Date or Redemption Date a
Debenture Event of Default has occurred and is continuing, no payment of any
Distribution on, or Redemption Price of, any of the Common Securities, and no
other payment on account of the redemption, liquidation or other acquisition of
such Common Securities, will be made unless payment in full in cash of all
accumulated and unpaid Distributions on all of the outstanding Preferred
Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all of the outstanding Preferred Securities then called for redemption,
will have been made or provided for, and 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 Preferred Securities then due and
payable.
 
    In the case of any Event of Default resulting from a Debenture Event of
Default, the Company as holder of the Common Securities will be deemed to have
waived any right to act with respect to any such Event of Default under the
Trust Agreement until the effect of all such Events of Default with respect to
the Preferred Securities have been cured, waived or otherwise eliminated. Until
any such Events of Default under the Trust Agreement with respect to the
Preferred Securities has been so cured, waived or otherwise eliminated, the
Property Trustee will act solely on behalf of the holders of the Preferred
Securities and not on behalf of the Company, as holder of the Common Securities,
and only the holders of the Preferred Securities will have the right to direct
the Property Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
 
    The Company will have the right at any time to dissolve, wind-up or
terminate IUB Trust and cause the Subordinated Debentures to be distributed to
the holders of the Preferred Securities. Such right is subject, however, to the
Company having received prior approval of the Federal Reserve if then required
under applicable capital guidelines or policies of the Federal Reserve.
 
    Pursuant to the Trust Agreement, IUB Trust will automatically terminate upon
expiration of its term and will terminate earlier on the first to occur of (i)
certain events of bankruptcy, dissolution or liquidation of the Company, (ii)
the distribution of a Like Amount of the Subordinated Debentures to the holders
of its Trust Securities, if the Company, as depositor, has given written
direction to the Property Trustee to terminate IUB Trust (which direction is
optional and wholly within the discretion of the Company, as depositor), (iii)
redemption of all of the Preferred Securities as described under "--Redemption--
 
                                       73
<PAGE>
Mandatory Redemption," or (iv) the entry of an order for the dissolution of IUB
Trust by a court of competent jurisdiction.
 
    If an early termination occurs as described in clause (i), (ii) or (iv) of
the preceding paragraph, IUB Trust will be liquidated by the Trustees as
expeditiously as the Trustees determine to be possible by distributing, after
satisfaction of liabilities to creditors of IUB Trust as provided by applicable
law, to the holders of such Trust Securities a Like Amount of the Subordinated
Debentures, unless such distribution is determined by the Property Trustee not
to be practical, in which event such holders will be entitled to receive out of
the assets of IUB Trust available for distribution to holders, after
satisfaction of liabilities to creditors of IUB Trust as provided by applicable
law, an amount equal to, in the case of holders of Preferred Securities, the
aggregate of the Liquidation Amount plus accrued and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"). If such Liquidation Distribution can be paid only in part
because IUB Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then the amounts payable directly by IUB Trust on the
Preferred Securities will be paid on a pro rata basis. The Company, as the
holder of the Common Securities, will be entitled to receive distributions upon
any such liquidation pro rata with the holders of the Preferred Securities,
except that, if a Debenture Event of Default has occurred and is continuing, the
Preferred Securities will have a priority over the Common Securities. See
"--Subordination of the Common Securities."
 
    Under current United States Federal income tax law and interpretations and
assuming, as expected, that IUB Trust is treated as a grantor trust, a
distribution of the Subordinated Debentures should not be a taxable event to
holders of the Preferred Securities. Should there be a change in law, a change
in legal interpretation, a Tax Event or other circumstances, however, the
distribution could be a taxable event to holders of the Preferred Securities.
See "Certain Federal Income Tax Consequences--Receipt of Subordinated Debentures
or Cash Upon Liquidation of IUB Trust." If the Company elects neither to redeem
the Subordinated Debentures prior to maturity nor to liquidate IUB Trust and
distribute the Subordinated Debentures to holders of the Preferred Securities,
the Preferred Securities will remain outstanding until the repayment of the
Subordinated Debentures.
 
    If the Company elects to liquidate IUB Trust and thereby causes the
Subordinated Debentures to be distributed to holders of the Preferred Securities
in liquidation of IUB Trust, the Company will continue to have the right to
shorten or extend the maturity of such Subordinated Debentures, subject to
certain conditions. See "Description of the Subordinated Debentures--General."
 
LIQUIDATION VALUE
 
    The amount of the Liquidation Distribution payable on the Preferred
Securities in the event of any liquidation of IUB Trust is $10 per Preferred
Security plus accrued and unpaid Distributions thereon to the date of payment,
which may be in the form of a distribution of such amount in Subordinated
Debentures, subject to certain exceptions. See "--Liquidation Distribution upon
Termination."
 
EVENTS OF DEFAULT; NOTICE
 
    Any one of the following events constitutes an event of default under the
Trust Agreement (an "Event of Default") with respect to the Preferred Securities
(whatever the reason for such Event of Default and whether voluntary or
involuntary or 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):
 
        (i) the occurrence of a Debenture Event of Default (see "Description of
    the Subordinated Debentures--Debenture Events of Default");
 
                                       74
<PAGE>
        (ii) default by IUB Trust or the Property Trustee in the payment of any
    Distribution when it becomes due and payable, and continuation of such
    default for a period of 30 days;
 
       (iii) default by IUB Trust or the Property Trustee in the payment of any
    Redemption Price of any Trust Security when it becomes due and payable;
 
        (iv) default in the performance, or breach, in any material respect, of
    any covenant or warranty of the Trustees in the Trust Agreement (other than
    a covenant or warranty a default in the performance of which or the breach
    of which is dealt with in clauses (ii) or (iii) above), and continuation of
    such default or breach for a period of 60 days after there has been given,
    by registered or certified mail, to the defaulting Trustee(s) by the holders
    of at least 25% in aggregate Liquidation Amount of the outstanding Preferred
    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"
    under the Trust Agreement; or
 
        (v) the occurrence of certain events of bankruptcy or insolvency with
    respect to the Property Trustee and the failure by the Company to appoint a
    successor Property Trustee within 60 days thereof.
 
    Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee will transmit
notice of such Event of Default to the holders of the Preferred Securities, the
Administrative Trustees and the Company, as depositor, unless such Event of
Default has been cured or waived. The Company, as depositor, and the
Administrative Trustees are required to file annually with the Property Trustee
a certificate as to whether or not they are in compliance with all the
conditions and covenants applicable to them under the Trust Agreement.
 
    If a Debenture Event of Default has occurred and is continuing, the
Preferred Securities will have a preference over the Common Securities upon
termination of IUB Trust. See "--Liquidation Distribution upon Termination." The
existence of an Event of Default does not entitle the holders of Preferred
Securities to accelerate the maturity thereof.
 
REMOVAL OF IUB TRUST TRUSTEES
 
    Unless a Debenture Event of Default has occurred and is 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 Preferred Securities. In no
event, however, will the holders of the Preferred Securities have the right to
vote to appoint, remove or replace the Administrative Trustees, which voting
rights are vested exclusively in the Company as the holder of the Common
Securities. No resignation or removal of a Trustee and no appointment of a
successor trustee will be effective until the acceptance of appointment by the
successor trustee in accordance with the provisions of the Trust Agreement.
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
 
    Unless an Event of Default has occurred and is continuing, at any time or
times, for the purpose of meeting the legal requirements of the Trust Indenture
Act or of any jurisdiction in which any part of the Trust Property (as defined
in the Trust Agreement) may at the time be located, the Company, as the holder
of the Common Securities, will have power to appoint one or more Persons (as
defined in the Trust Agreement) either to act as a co-trustee, jointly with the
Property Trustee, of all or any part of such Trust Property, or to act as
separate trustee of any such Trust Property, in either case with such powers as
may be provided in the instrument of appointment, and to vest in such Person or
Persons in such capacity any property, title, right or power deemed necessary or
desirable, subject to the provisions of the Trust Agreement. In case a Debenture
Event of Default has occurred and is continuing, the Property Trustee alone will
have power to make such appointment.

MERGER OR CONSOLIDATION OF TRUSTEES
 
    Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Trustee is a party, or any Person
succeeding to all or substantially all the corporate trust business of such
Trustee, will be the successor of such Trustee under the Trust Agreement,
provided such Person is otherwise qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF IUB TRUST
 
    IUB Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, except as described below. IUB Trust
may, at the request of the Company, with the consent of the Administrative
Trustees and without the consent of the holders of the Preferred Securities, the
Property Trustee or the Delaware Trustee, merge with or into, consolidate,
amalgamate, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to a trust organized as such under the laws
of any state; provided, that (i) such successor entity either (a) expressly
assumes all of the obligations of IUB Trust with respect to the Preferred
Securities, or (b) substitutes for the Preferred Securities other securities
having substantially the same terms as the Preferred Securities (the "Successor
Securities") so long as the Successor Securities rank the same as the Preferred
Securities rank in priority with respect to distributions and payments upon
liquidation, redemption and otherwise, (ii) the Company expressly appoints a
trustee of such successor entity possessing the same powers and duties as the
Property Trustee in its capacity as the holder of the Subordinated Debentures,
(iii) the Successor Securities are listed, or any Successor Securities will be
listed upon notification of issuance, on any national securities exchange or
other organization on which the Preferred Securities are then listed (including,
if applicable, the Nasdaq National Market), if any, (iv) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Preferred Securities (including any Successor Securities) in any material
respect, (v) prior to such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, the Company has received an opinion from
independent counsel to the effect that (a) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the holders of the Preferred
Securities (including any Successor Securities) in any material respect, and (b)
following such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease, neither IUB Trust nor such successor entity will be required
to register as an "investment company" under the Investment Company Act, and
(vi) the Company owns all of the common securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Guarantee, the Indenture, the
Subordinated Debentures, the Trust Agreement and the Expense Agreement.
Notwithstanding the foregoing, IUB Trust will not, except with the consent of
holders of 100% in Liquidation Amount of the Preferred Securities, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets substantially as an entirety to any other Person or
permit any other Person to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger, replacement, conveyance,
transfer or lease would cause IUB Trust or the successor entity to be classified
as other than a grantor trust for United States Federal income tax purposes.
 
VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT
 
    Except as provided below and under "Description of the Guarantee--Amendments
and Assignment" and as otherwise required by the Trust Act and the Trust
Agreement, the holders of the Preferred Securities will have no voting rights.
 
    The Trust Agreement may be amended from time to time by the Company, the
Property Trustee and the Administrative Trustees, without the consent of the
holders of the Preferred Securities (i) with respect to acceptance of
appointment by a successor trustee, (ii) to cure any ambiguity, correct or
supplement any
 
                                       76
<PAGE>
provisions in such 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 (provided such amendment is not inconsistent
with the other provisions of the Trust Agreement), (iii) to modify, eliminate or
add to any provisions of the Trust Agreement to such extent as is necessary to
ensure that IUB Trust will be classified for United States Federal income tax
purposes as a grantor trust at all times that any Trust Securities are
outstanding or to ensure that IUB Trust will not be required to register as an
"investment company" under the Investment Company Act, or (iv) to reduce or
increase the Liquidation Amount per Trust Security and simultaneously to
increase or reduce the number of Trust Securities issued and outstanding solely
for the purpose of maintaining the eligibility of the Preferred Securities for
listing or quotation on any national securities exchange or other organization
on which the Preferred Securities are then listed or quoted (including, if
applicable, the Nasdaq National Market); provided, however, that in the case of
clause (ii), such action may not adversely affect in any material respect the
interests of any holder of Trust Securities and that, in the case of clause
(iv), the aggregate Liquidation Amount of the Trust Securities outstanding, upon
completion of any such reduction or increase, must be the same as the aggregate
Liquidation Amount of the Trust Securities outstanding immediately prior to any
such reduction or increase, and any amendments of such Trust Agreement will
become effective when notice thereof is given to the holders of Trust Securities
(or, in the case of an amendment pursuant to clause (iv), as of the date
specified in the notice). The Trust Agreement may be amended by the Trustees and
the Company with (i) the consent of holders representing not less than a
majority in the aggregate Liquidation Amount of the outstanding Trust
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 IUB Trust's status as a
grantor trust for United States Federal income tax purposes or IUB Trust's
exemption from status as an "investment company" under the Investment Company
Act. Notwithstanding anything in this paragraph to the contrary, without the
consent of each holder of Trust Securities, the Trust Agreement may not be
amended to (a) change the amount or timing of any Distribution on the Trust
Securities or otherwise adversely affect the amount of any Distribution required
to be made in respect of the Trust Securities as of a specified date, or (b)
restrict the right of a holder of Trust Securities to institute suit for the
enforcement of any such payment on or after such date.
 
    The Trustees will not, so long as any Subordinated Debentures are held by
the Property Trustee, (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 the Property Trustee with respect to the
Subordinated Debentures, (ii) waive any past default that is waivable under the
Indenture, (iii) exercise any right to rescind or annul a declaration that the
principal of all the Subordinated Debentures will be due and payable, or (iv)
consent to any amendment, modification or termination of the Indenture or the
Subordinated Debentures, where such consent is required, without, in each case,
obtaining the prior approval of the holders of a majority in aggregate
Liquidation Amount of all outstanding Preferred Securities; provided, however,
that where a consent under the Indenture requires the consent of each holder of
Subordinated Debentures affected thereby, no such consent will be given by the
Property Trustee without the prior consent of each holder of the Preferred
Securities. The Trustees may not revoke any action previously authorized or
approved by a vote of the holders of the Preferred Securities except by
subsequent vote of the holders of the Preferred Securities. The Property Trustee
will notify each holder of Preferred Securities of any notice of default with
respect to the Subordinated Debentures. In addition to obtaining the foregoing
approvals of the holders of the Preferred Securities, prior to taking any of the
foregoing actions, the Trustees must obtain an opinion of counsel experienced in
such matters to the effect that IUB Trust will not be classified as an
association taxable as a corporation for United States Federal income tax
purposes on account of such action.
 
    Any required approval of holders of Preferred Securities may be given at a
meeting of holders of Preferred Securities convened for such purpose or pursuant
to written consent. The Property Trustee will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
 
                                       77
<PAGE>
upon which action by written consent of such holders is to be taken, to be given
to each holder of record of Preferred Securities in the manner set forth in the
Trust Agreement.
 
    No vote or consent of the holders of Preferred Securities will be required
for IUB Trust to redeem and cancel its Preferred Securities in accordance with
the Trust Agreement.
 
    Notwithstanding the fact that holders of Preferred Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned by the Company, the Trustees or any
affiliate of the Company or any Trustee will, for purposes of such vote or
consent, be treated as if they were not outstanding.
 
PAYMENT AND PAYING AGENCY
 
    Payments in respect of the Preferred Securities will be made by check mailed
to the address of the holder entitled thereto as such address will appear on the
register of holders of the Preferred Securities. The paying agent for the
Preferred Securities will initially be the Property Trustee and any co-paying
agent chosen by the Property Trustee and acceptable to the Administrative
Trustees and the Company. The paying agent for the Preferred Securities may
resign as paying agent upon 30 days' written notice to the Property Trustee and
the Company. In the event that the Property Trustee no longer is the paying
agent for the Preferred Securities, the Administrative Trustees will appoint a
successor (which must be a bank or trust company acceptable to the
Administrative Trustees and the Company) to act as paying agent.
 
REGISTRAR AND TRANSFER AGENT
 
    The Property Trustee will act as the registrar and the transfer agent for
the Preferred Securities. Registration of transfers of Preferred Securities will
be effected without charge by or on behalf of IUB Trust, but upon payment of any
tax or other governmental charges that may be imposed in connection with any
transfer or exchange. IUB Trust will not be required to register or cause to be
registered the transfer of Preferred Securities after such Preferred Securities
have been called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
    The Property Trustee, other than upon the occurrence and during the
continuance of an Event of Default, undertakes to perform only such duties as
are specifically set forth in the Trust Agreement and, upon the occurrence and
during the continuance of an Event of Default, 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 under no
obligation to exercise any of the powers vested in it by the Trust Agreement at
the request of any holder of Preferred Securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred thereby. If no Event of Default has occurred and is continuing 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 Preferred Securities are entitled under the Trust Agreement
to vote, then the Property Trustee will take such action as is directed by the
Company and if not so directed, will take such action as it deems advisable and
in the best interests of the holders of the Trust 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 IUB Trust in such a way that IUB Trust will not be
deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as an association taxable as a corporation
for United States Federal income tax purposes and so that the Subordinated
Debentures will be treated as indebtedness of the Company for United States
Federal income tax purposes. The Company and the
 
                                       78
<PAGE>
Administrative Trustees are authorized, in this connection, to take any action,
not inconsistent with applicable law, the certificate of trust of IUB Trust or
the Trust Agreement, that the Company and the Administrative Trustees determine
in their discretion to be necessary or desirable for such purposes.
 
    Holders of the Preferred Securities have no preemptive or similar rights.
 
    The Trust Agreement and the Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.
 
                   DESCRIPTION OF THE SUBORDINATED DEBENTURES
 
    Concurrently with the issuance of the Preferred Securities, IUB Trust will
invest the proceeds thereof, together with the consideration paid by the Company
for the Common Securities, in the Subordinated Debentures issued by the Company.
The Subordinated Debentures will be issued as unsecured debt under the
Indenture, to be dated as of       , 1997 (the "Indenture"), between the Company
and State Street Bank and Trust Company, as trustee (the "Debenture Trustee").
The Indenture will be qualified as an indenture under the Trust Indenture Act.
The following summary of the material terms and provisions of the Subordinated
Debentures and the Indenture does not purport to be complete and is subject to,
and is qualified in its entirety by reference to, the Indenture and the Trust
Indenture Act. Wherever particular defined terms of the Indenture are referred
to, but not defined herein, such defined terms are incorporated herein by
reference. The form of the Indenture has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part.
 
GENERAL
 
    The Subordinated Debentures will be limited in aggregate principal amount to
approximately $19,072,170 (or $21,932,990 if the option described under the
heading "Underwriting" is exercised by the Underwriter), such amount being the
sum of the aggregate stated Liquidation Amount of the Trust Securities. The
Subordinated Debentures will bear interest at the annual rate of    % of the
principal amount thereof, payable quarterly in arrears on March 31, June 30,
September 30, and December 31 of each year (each, an "Interest Payment Date")
beginning       , 1997, to the Person (as defined in the Indenture) in whose
name each Subordinated Debenture is registered, subject to certain exceptions,
at the close of business on the fifteenth day of the last month of the calendar
quarter. It is anticipated that, until the liquidation, of IUB Trust, the
Subordinated Debentures will be held in the name of the Property Trustee in
trust for the benefit of the holders of the Preferred Securities. The amount of
interest payable for any period will be computed on the basis of a 360-day year
of twelve 30-day months. In the event that any date on which interest is payable
on the Subordinated Debentures is not a Business Day, then payment of the
interest 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), with the same force and effect as if made on the date such payment was
originally payable. Accrued interest that is not paid on the applicable Interest
Payment Date will bear additional interest on the amount thereof (to the extent
permitted by law) at the rate per annum of    % thereof, compounded quarterly.
The term "interest," as used herein, includes quarterly interest payments,
interest on quarterly interest payments not paid on the applicable Interest
Payment Date and Additional Payments, as applicable.
 
    The Subordinated Debentures will mature on December 31, 2027 (such date, as
it may be shortened or extended as hereinafter described, the "Stated
Maturity"). Such date may be shortened at any time by the Company to any date
not earlier than December 31, 2002, subject to the Company having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies of the Federal Reserve. Such date may also be extended at
any time at the election of the Company but in no event to a date later than
December 31, 2036, provided that at the time such election is made and at the
time of extension (i) the Company is not in bankruptcy, otherwise insolvent or
in liquidation, (ii) the Company is not in default in the payment of any
interest or principal on the Subordinated Debentures, (iii) IUB Trust is not in
arrears on payments of Distributions on the Preferred Securities and no deferred
 
                                       79
<PAGE>
Distributions are accumulated, and (iv) the Company has a Senior Debt rating of
investment grade. In the event that the Company elects to shorten or extend the
Stated Maturity of the Subordinated Debentures, it will give notice thereof to
the Debenture Trustee, IUB Trust and to the holders of the Subordinated
Debentures no more than 180 days and no less than 90 days prior to the
effectiveness thereof. The Company will not have the right to purchase the
Subordinated Debentures, in whole or in part, from IUB Trust until after
December 31, 2002, except if a Tax Event, a Capital Treatment Event or an
Investment Company Event has occurred and is continuing.
 
    The Subordinated Debentures will be unsecured and will rank junior and be
subordinate in right of payment to all Senior Debt, Subordinated Debt and
Additional Senior Obligations of the Company. Because the Company is a holding
company, the right of the Company to participate in any distribution of assets
of any Subsidiary Bank, upon any such Subsidiary Bank's liquidation or
reorganization or otherwise (and thus the ability of holders of the Subordinated
Debentures to benefit indirectly from such distribution), is subject to the
prior claim of creditors of such Subsidiary Bank, except to the extent that the
Company may itself be recognized as a creditor of such Subsidiary Bank. The
Subordinated Debentures will, therefore, be effectively subordinated to all
existing and future liabilities of the Subsidiary Banks, and holders of
Subordinated Debentures should look only to the assets of the Company for
payments on the Subordinated Debentures. The Indenture does not limit the
incurrence or issuance of other secured or unsecured debt of the Company,
including Senior Debt, Subordinated Debt and Additional Senior Obligations,
whether under the Indenture or any existing indenture or other indenture that
the Company may enter into in the future or otherwise. See "--Subordination."
 
    The Indenture does not contain provisions that afford holders of the
Subordinated Debentures protection in the event of a highly leveraged
transaction or other similar transaction involving the Company that may
adversely affect such holders.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
    The Company has the right under the Indenture at any time during the term of
the Subordinated Debentures, so long as no Debenture Event of Default has
occurred and is continuing, to defer the payment of interest at any time, or
from time to time (each, an "Extension Period"). The right to defer the payment
of interest on the Subordinated Debentures is limited, however, to a period, in
each instance, not exceeding 20 consecutive quarters and no Extension Period may
extend beyond the Stated Maturity of the Subordinated Debentures. At the end of
each Extension Period, the Company must pay all interest then accrued and unpaid
(together with interest thereon at the annual rate of    %, compounded
quarterly, to the extent permitted by applicable law). During an Extension
Period, interest will continue to accrue and holders of Subordinated Debentures
(or the holders of Preferred Securities if such securities are then outstanding)
will be required to accrue and recognize income for United States Federal income
tax purposes. See "Certain Federal Income Tax Consequences--Potential Extension
of Interest Payment Period and Original Issue Discount."
 
    During any such Extension Period, the Company may 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 Company's capital stock, (ii)
make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Company that rank PARI PASSU
with or junior in interest to the Subordinated Debentures or make any guarantee
payments with respect to any guarantee by the Company of the debt securities of
any subsidiary of the Company if such guarantee ranks PARI PASSU or junior in
interest to the Subordinated Debentures (other than payments under the
Guarantee), or (iii) redeem, purchase or acquire less than all of the
Subordinated Debentures or any of the Preferred Securities. Prior to the
termination of any such Extension Period, the Company may further defer the
payment of interest; provided that no Extension Period may exceed 20 consecutive
quarters or extend beyond the Stated Maturity of the Subordinated Debentures.
Upon the termination of any such Extension Period and the payment of all amounts
then due on any Interest Payment Date, the Company may elect to
 
                                       80
<PAGE>
begin a new Extension Period subject to the above requirements. No interest will
be due and payable during an Extension Period, except at the end thereof. The
Company has no present intention of exercising its rights to defer payments of
interest on the Subordinated Debentures. The Company must give the Property
Trustee, the Administrative Trustees and the Debenture Trustee notice of its
election of such Extension Period at least two Business Days prior to the
earlier of (i) the next succeeding date on which Distributions on the Trust
Securities would have been payable except for the election to begin such
Extension Period, or (ii) the date the Trust is required to give notice of the
record date, or the date such Distributions are payable, to the Nasdaq National
Market (or other applicable self-regulatory organization) or to holders of the
Preferred Securities, but in any event at least one Business Day before such
record date. Subject to the foregoing, there is no limitation on the number of
times that the Company may elect to begin an Extension Period.
 
ADDITIONAL SUMS
 
    If IUB Trust or the Property Trustee is required to pay any additional
taxes, duties or other governmental charges as a result of the occurrence of a
Tax Event, the Company will pay to the holders of the Subordinated Debentures as
additional amounts (referred to herein as "Additional Payments") on the
Subordinated Debentures such additional amounts as may be required so that the
net amounts received and retained by IUB Trust after paying any such additional
taxes, duties or other governmental charges will not be less than the amounts
IUB Trust would have received had such additional taxes, duties or other
governmental charges not been imposed.
 
REDEMPTION OR EXCHANGE
 
    The Company will have the right to redeem the Subordinated Debentures prior
to maturity (i) on or after December 31, 2002, in whole at any time or in part
from time to time, or (ii) at any time in whole (but not in part), within 180
days following the occurrence of a Tax Event, a Capital Treatment Event or an
Investment Company Event, in each case at a redemption price equal to the
accrued and unpaid interest on the Subordinated Debentures so redeemed to the
date fixed for redemption, plus 100% of the principal amount thereof. Any such
redemption prior to the Stated Maturity will be subject to prior approval of the
Federal Reserve if then required under applicable capital guidelines or policies
of the Federal Reserve.
 
    "Tax Event" means the receipt by IUB Trust of an opinion of counsel
experienced in such matters to the effect that, as a result of 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 as a result of 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 issuance of the
Preferred Securities under the Trust Agreement, there is more than an
insubstantial risk that (i) interest payable by the Company on the Subordinated
Debentures is not, or within 90 days of the date of such opinion will not be,
deductible by the Company, in whole or in part, for United States Federal income
tax purposes, (ii) IUB Trust is, or will be within 90 days after the date of
such opinion of counsel, subject to United States Federal income tax with
respect to income received or accrued on the Subordinated Debentures, or (iii)
IUB Trust is, or will be within 90 days after the date of such opinion of
counsel, subject to more than a de minimis amount of other taxes, duties,
assessments or other governmental charges. The Company must request and receive
an opinion with regard to such matters within a reasonable period of time after
it becomes aware of the possible occurrence of any of the events described in
clauses (i) through (iii) above.
 
    "Capital Treatment Event" means the receipt by IUB Trust of an opinion of
counsel experienced in such matters to the effect that, as a result of any
amendment to or any change (including any announced prospective change) in the
laws (or any regulations thereunder) of the United States or any political
subdivision thereof or therein, or as a result of any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or such
 
                                       81
<PAGE>
proposed change, pronouncement or decision is announced on or after the date of
issuance of the Preferred Securities under the Trust Agreement, there is more
than an insubstantial risk of impairment of the Company's ability to treat the
aggregate Liquidation Amount of the Preferred Securities (or any substantial
portion thereof) as "Tier 1 capital" (or the then equivalent thereof) for
purposes of the capital adequacy guidelines of the Federal Reserve, as then
applicable to the Company, provided, however, that the inability of the Company
to treat all or any portion of the Liquidation Amount of the Preferred
Securities as Tier 1 capital shall not constitute the basis for a Capital
Treatment Event if such inability results from the Company having cumulative
preferred capital in excess of the amount which may qualify for treatment as
Tier 1 capital under applicable capital adequacy guidelines of the Federal
Reserve.
 
    "Investment Company Event" means the receipt by IUB Trust of an opinion of
counsel experienced in such matters to the effect that, as a result of the
occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority, IUB Trust is or will be considered an
"investment company" that is required to be registered under the Investment
Company Act, which change becomes effective on or after the date of original
issuance of the Preferred Securities.
 
    Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Subordinated Debentures to
be redeemed at its registered address. Unless the Company defaults in payment of
the redemption price for the Subordinated Debentures, on and after the
redemption date interest ceases to accrue on such Subordinated Debentures or
portions thereof called for redemption.
 
    The Subordinated Debentures will not be subject to any sinking fund.
 
DISTRIBUTION UPON LIQUIDATION
 
    As described under "Description of the Preferred Securities--Liquidation
Distribution upon Termination," under certain circumstances involving the
termination of IUB Trust, the Subordinated Debentures may be distributed to the
holders of the Preferred Securities in liquidation of IUB Trust after
satisfaction of liabilities to creditors of IUB Trust as provided by applicable
law. Any such distribution will be subject to receipt of prior approval by the
Federal Reserve if then required under applicable policies or guidelines of the
Federal Reserve. If the Subordinated Debentures are distributed to the holders
of Preferred Securities upon the liquidation of IUB Trust, the Company will use
its best efforts to list the Subordinated Debentures on the Nasdaq National
Market or such stock exchanges, if any, on which the Preferred Securities are
then listed. There can be no assurance as to the market price of any
Subordinated Debentures that may be distributed to the holders of Preferred
Securities.
 
RESTRICTIONS ON CERTAIN PAYMENTS
 
    If at any time (i) there has occurred a Debenture Event of Default, (ii) the
Company is in default with respect to its obligations under the Guarantee, or
(iii) the Company has given notice of its election of an Extension Period as
provided in the Indenture with respect to the Subordinated Debentures and has
not rescinded such notice, or such Extension Period, or any extension thereof,
is continuing, the Company will not (1) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock, (2) make any payment of
principal, interest or premium, if any, on or repay or repurchase or redeem any
debt securities of the Company that rank PARI PASSU with or junior in interest
to the Subordinated Debentures or make any guarantee payments with respect to
any guarantee by the Company of the debt securities of any subsidiary of the
Company if such guarantee ranks PARI PASSU or junior in interest to the
Subordinated Debentures (other than payments under the Guarantee), or (3)
redeem, purchase or acquire less than all of the Subordinated Debentures or any
of the Preferred Securities.
 
                                       82
<PAGE>
SUBORDINATION
 
    The Indenture provides that the Subordinated Debentures are subordinated and
junior in right of payment to all Senior Debt, Subordinated Debt and Additional
Senior Obligations of the Company. Upon any payment or distribution of assets to
creditors upon any liquidation, dissolution, winding up, reorganization,
assignment for the benefit of creditors, marshaling of assets or any bankruptcy,
insolvency, debt restructuring or similar proceedings in connection with any
insolvency or bankruptcy proceedings of the Company, the holders of Senior Debt,
Subordinated Debt and Additional Senior Obligations of the Company will first be
entitled to receive payment in full of principal of (and premium, if any) and
interest, if any, on such Senior Debt, Subordinated Debt and Additional Senior
Obligations of the Company before the holders of Subordinated Debentures will be
entitled to receive or retain any payment in respect of the principal of or
interest on the Subordinated Debentures.
 
    In the event of the acceleration of the maturity of any Subordinated
Debentures, the holders of all Senior Debt, Subordinated Debt and Additional
Senior Obligations of the Company outstanding at the time of such acceleration
will first be entitled to receive payment in full of all amounts due thereon
(including any amounts due upon acceleration) before the holders of the
Subordinated Debentures will be entitled to receive or retain any payment in
respect of the principal of or interest on the Subordinated Debentures.
 
    No payments on account of principal or interest in respect of the
Subordinated Debentures may be made if there has occurred and is continuing a
default in any payment with respect to Senior Debt, Subordinated Debt or
Additional Senior Obligations of the Company or an event of default with respect
to any Senior Debt, Subordinated Debt or Additional Senior Obligations of the
Company resulting in the acceleration of the maturity thereof, or if any
judicial proceeding is pending with respect to any such default.
 
    "Debt" means, with respect to any Person, whether recourse is to all or a
portion of the assets of such Person and whether or not contingent, (i) every
obligation of such person for money borrowed, (ii) every obligation of such
Person evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses, (iii) every reimbursement obligation of such Person with
respect to letters of credit, bankers' acceptances or similar facilities issued
for the account of such Person, (iv) every obligation of such Person issued or
assumed as the deferred purchase price of property or services (but excluding
trade accounts payable or accrued liabilities arising in the ordinary course of
business), (v) every capital lease obligation of such Person, and (vi) and every
obligation of the type referred to in clauses (i) through (v) of another Person
and all dividends of another Person the payment of which, in either case, such
Person has guaranteed or is responsible or liable, directly or indirectly, as
obligor or otherwise.
 
    "Senior Debt" means, with respect to the Company, the principal of (and
premium, if any) and interest, if any (including interest accruing on or after
the filing of any petition in bankruptcy or for reorganization relating to the
Company whether or not such claim for post-petition interest is allowed in such
proceeding), on Debt, whether incurred on or prior to the date of the Indenture
or thereafter incurred, unless, in the instrument creating or evidencing the
same or pursuant to which the same is outstanding, it is provided that such
obligations are not superior in right of payment to the Subordinated Debentures
or to other Debt which is PARI PASSU with, or subordinated to, the Subordinated
Debentures; provided, however, that Senior Debt will not be deemed to include
(i) any Debt of the Company which when incurred and without respect to any
election under section 1111(b) of the United States Bankruptcy Code of 1978, as
amended, was without recourse to the Company, (ii) any Debt of the Company to
any of its subsidiaries, (iii) any Debt to any employee of the Company, (iv) any
Debt which by its terms is subordinated to trade accounts payable or accrued
liabilities arising in the ordinary course of business to the extent that
payments made to the holders of such Debt by the holders of the Subordinated
Debentures as a result of the subordination provisions of the Indenture would be
greater than they otherwise would have been as a result of any obligation of
such holders to pay amounts over to the obligees on such trade accounts payable
or accrued liabilities arising in the ordinary course of business as a result of
subordination provisions to which such Debt is subject, and (v) Debt which
constitutes Subordinated Debt.
 
                                       83
<PAGE>
    "Subordinated Debt" means, with respect to the Company, the principal of
(and premium, if any) and interest, if any (including interest accruing on or
after the filing of any petition in bankruptcy or for reorganization relating to
the Company whether or not such claim for post-petition interest is allowed in
such proceeding), on Debt, whether incurred on or prior to the date of the
Indenture or thereafter incurred, which is by its terms expressly provided to be
junior and subordinate to other Debt of the Company (other than the Subordinated
Debentures).
 
    "Additional Senior Obligations" means, with respect to the Company, all
indebtedness, whether incurred on or prior to the date of the Indenture or
thereafter incurred, for claims in respect of derivative products such as
interest and foreign exchange rate contracts, commodity contracts and similar
arrangements; provided, however, that Additional Senior Obligations do not
include claims in respect of Senior Debt or Subordinated Debt or obligations
which, by their terms, are expressly stated to be not superior in right of
payment to the Subordinated Debentures or to rank PARI PASSU in right of payment
with the Subordinated Debentures. "Claim," as used herein, has the meaning
assigned thereto in Section 101(4) of the United States Bankruptcy Code of 1978,
as amended.
 
    The Indenture places no limitation on the amount of additional Senior Debt,
Subordinated Debt or Additional Senior Obligations that may be incurred by the
Company. The Company expects from time to time to incur additional indebtedness
constituting Senior Debt, Subordinated Debt and Additional Senior Obligations.
As of September 30, 1997, the Company had aggregate Senior Debt, Subordinated
Debt and Additional Senior Obligations of approximately $4.6 million. Because
the Company is a holding company, the Subordinated Debentures are effectively
subordinated to all existing and future liabilities of the Company subsidiaries,
including obligations to depositors of Union Bank, Regional Bank and any other
bank that may become a subsidiary of the Company.
 
PAYMENT AND PAYING AGENTS
 
    Payment of principal of and any interest on the Subordinated Debentures will
be made at the office of the Debenture Trustee in Boston, Massachusetts, except
that, at the option of the Company, payment of any interest may be made (i) by
check mailed to the address of the Person entitled thereto as such address
appears in the register of holders of the Subordinated Debentures, or (ii) by
transfer to an account maintained by the Person entitled thereto as specified in
the register of holders of the Subordinated Debentures, provided that proper
transfer instructions have been received by the regular record date. Payment of
any interest on Subordinated Debentures will be made to the Person in whose name
such Subordinated Debenture is registered at the close of business on the
regular record date for such interest, except in the case of defaulted interest.
The Company may at any time designate additional paying agents for the
Subordinated Debentures or rescind the designation of any paying agent for the
Subordinated Debentures; however, the Company will at all times be required to
maintain a paying agent in Boston, Massachusetts and each place of payment for
the Subordinated Debentures.
 
    Any moneys deposited with the Debenture Trustee or any paying agent for the
Subordinated Debentures, or then held by the Company in trust, for the payment
of the principal of or interest on the Subordinated Debentures and remaining
unclaimed for two years after such principal or interest has become due and
payable will be repaid to the Company on May 31 of each year or (if then held in
trust by the Company) will be discharged from such trust and the holder of such
Subordinated Debenture will thereafter look, as a general unsecured creditor,
only to the Company for payment thereof.
 
REGISTRAR AND TRANSFER AGENT
 
    The Debenture Trustee will act as the registrar and the transfer agent for
the Subordinated Debentures. Subordinated Debentures may be presented for
registration of transfer (with the form of transfer endorsed thereon, or a
satisfactory written instrument of transfer, duly executed), at the office of
the registrar in Boston, Massachusetts. The Company may at any time rescind the
designation of any such transfer agent or approve a change in the location
through which any such transfer agent acts. The Company may at any time
designate additional transfer agents with respect to the Subordinated
Debentures. In the event of any redemption, neither the Company nor the
Debenture Trustee will be required to
 
                                       84
<PAGE>
(i) issue, register the transfer of or exchange Subordinated Debentures during a
period beginning at the opening of business 15 days before the day of selection
for redemption of Subordinated Debentures and ending at the close of business on
the day of mailing of the relevant notice of redemption, or (ii) transfer or
exchange any Subordinated Debentures so selected for redemption, except, in the
case of any Subordinated Debentures being redeemed in part, any portion thereof
not to be redeemed.
 
MODIFICATION OF INDENTURE
 
    The Company and the Debenture Trustee may, from time to time without the
consent of the holders of the Subordinated Debentures, amend, waive or
supplement the Indenture for specified purposes, including, among other things,
curing ambiguities, defects or inconsistencies and qualifying, or maintaining
the qualification of, the Indenture under the Trust Indenture Act. The Indenture
contains provisions permitting the Company and the Debenture Trustee, with the
consent of the holders of not less than a majority in principal amount of the
outstanding Subordinated Debentures, to modify the Indenture; provided, that no
such modification may, without the consent of the holder of each outstanding
Subordinated Debenture affected by such proposed modification, (i) extend the
fixed maturity of the Subordinated Debentures, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
or (ii) reduce the percentage of principal amount of Subordinated Debentures,
the holders of which are required to consent to any such modification of the
Indenture; provided that so long as any of the Preferred Securities remain
outstanding, no such modification may be made that requires the consent of the
holders of the Subordinated Debentures, and no termination of the Indenture may
occur, and no waiver of any Debenture Event of Default may be effective, without
the prior consent of the holders of at least a majority of the aggregate
Liquidation Amount of the Preferred Securities and that if the consent of the
holder of each Subordinated Debenture is required, such modification will not be
effective until each holder of Trust Securities has consented thereto.
 
DEBENTURE EVENTS OF DEFAULT
 
    The Indenture provides that any one or more of the following described
events with respect to the Subordinated Debentures that has occurred and is
continuing constitutes an event of default (each, a "Debenture Event of
Default") with respect to the Subordinated Debentures:
 
        (i) failure for 30 days to pay any interest on the Subordinated
    Debentures, when due (subject to the deferral of any due date in the case of
    an Extension Period);
 
        (ii) failure to pay any principal on the Subordinated Debentures when
    due whether at maturity, upon redemption by declaration or otherwise;
 
       (iii) failure to observe or perform in any material respect certain other
    covenants contained in the Indenture for 90 days after written notice to the
    Company from the Debenture Trustee or the holders of at least 25% in
    aggregate outstanding principal amount of the Subordinated Debentures; or
 
        (iv) certain events in bankruptcy, insolvency or reorganization of the
    Company.
 
    The holders of a majority in aggregate outstanding principal amount of the
Subordinated Debentures have 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 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 Subordinated
Debentures may annul such declaration and waive the default if the default
(other than the non-payment of the principal of the 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.
Should the holders of the Subordinated Debentures fail to annul such declaration
and waive such default, the holders of a majority in aggregate Liquidation
Amount of the Preferred Securities will have such right.
 
                                       85
<PAGE>
    The Company is required to file annually with the Debenture Trustee a
certificate as to whether or not the Company is in compliance with all the
conditions and covenants applicable to it under the Indenture.
 
    If a Debenture Event of Default has occurred and is continuing, the Property
Trustee will have the right to declare the principal of and the interest on such
Subordinated Debentures, and any other amounts payable under the Indenture, to
be forthwith due and payable and to enforce its other rights as a creditor with
respect to such Subordinated Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF THE PREFERRED SECURITIES
 
    If a Debenture Event of Default has occurred and is continuing and such
event is attributable to the failure of the Company to pay interest on or
principal of the Subordinated Debentures on the payment date on which such
payment is due and payable, then a holder of Preferred Securities may institute
a legal proceeding directly against the Company for enforcement of payment to
such holder of the principal of or interest on such Subordinated Debentures
having a principal amount equal to the aggregate Liquidation Amount of the
Preferred Securities of such holder (a "Direct Action"). In connection with such
Direct Action, the Company will have a right of set-off under the Indenture to
the extent of any payment made by the Company to such holder of Preferred
Securities in the Direct Action. The Company may not amend the Indenture to
remove the foregoing right to bring a Direct Action without the prior written
consent of the holders of all of the Preferred Securities. If the right to bring
a Direct Action is removed, IUB Trust may become subject to the reporting
obligations under the Exchange Act. The Company has the right under the
Indenture to set-off any payment made to such holder of Preferred Securities by
the Company in connection with a Direct Action.
 
    The holders of the Preferred Securities will not be able to exercise
directly any remedies, other than those set forth in the preceding paragraph,
available to the holders of the Subordinated Debentures unless there has been an
Event of Default under the Trust Agreement. See "Description of the Preferred
Securities--Events of Default; Notice."
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
    The Company may not consolidate with or merge into any other Person or
convey or transfer its properties and assets substantially as an entirety to any
Person, and any Person may not consolidate with or merge into the Company or
sell, convey, transfer or otherwise dispose of its properties and assets
substantially as an entirety to the Company, unless (i) in the event the Company
consolidates with or merges into another Person or conveys or transfers its
properties and assets substantially as an entirety to any Person, the successor
Person is organized under the laws of the United States or any State or the
District of Columbia, and such successor Person expressly assumes by
supplemental indenture the Company's obligations on the Subordinated Debentures,
(ii) immediately after giving effect thereto, no Debenture Event of Default, and
no event which, after notice or lapse of time or both, would become a Debenture
Event of Default, has occurred and is continuing, and (iii) certain other
conditions as prescribed in the Indenture are met.
 
SATISFACTION AND DISCHARGE
 
    The Indenture will cease to be of further effect (except as to the Company's
obligations to pay certain sums due pursuant to the Indenture and to provide
certain officers' certificates and opinions of counsel described therein) and
the Company will be deemed to have satisfied and discharged the Indenture when,
among other things, all Subordinated Debentures not previously delivered to the
Debenture Trustee for cancellation (i) have become due and payable, or (ii) will
become due and payable at their Stated Maturity within one year or are to be
called for redemption within one year, and the Company deposits or causes 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
Subordinated Debentures not previously delivered to the
 
                                       86
<PAGE>
Debenture Trustee for cancellation, for the principal and interest to the date
of the deposit or to the Stated Maturity or redemption date, as the case may be.
Governing Law
 
    The Indenture and the Subordinated Debentures will be governed by and
construed in accordance with the laws of the State of Indiana.
 
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
    The Debenture Trustee has and is 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 under no
obligation to exercise any of the powers vested in it by the Indenture at the
request of any holder of Subordinated Debentures, unless offered reasonable
indemnity by such 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 if the Debenture Trustee reasonably believes that repayment or
adequate indemnity is not reasonably assured to it.
 
MISCELLANEOUS
 
    The Company has agreed, pursuant to the Indenture, for so long as Trust
Securities remain outstanding, (i) to maintain directly or indirectly 100%
ownership of the Common Securities of IUB Trust (provided that certain
successors which are permitted pursuant to the Indenture may succeed to the
Company's ownership of the Common Securities), (ii) not to voluntarily
terminate, wind up or liquidate IUB Trust, except upon prior approval of the
Federal Reserve if then so required under applicable capital guidelines or
policies of the Federal Reserve, and (a) in connection with a distribution of
Subordinated Debentures to the holders of the Preferred Securities in
liquidation of IUB Trust, or (b) in connection with certain mergers,
consolidations or amalgamations permitted by the Trust Agreement, and (iii) to
use its reasonable efforts, consistent with the terms and provisions of the
Trust Agreement, to cause IUB Trust to remain classified as a grantor trust and
not as an association taxable as a corporation for United States Federal income
tax purposes.
 
                          DESCRIPTION OF THE GUARANTEE
 
    The Preferred Securities Guarantee Agreement (the "Guarantee") will be
executed and delivered by the Company concurrently with the issuance of the
Preferred Securities for the benefit of the holders of the Preferred Securities.
The Guarantee will be qualified as an indenture under the Trust Indenture Act.
The Guarantee Trustee will act as indenture trustee under the Guarantee for
purposes of complying with the provisions of the Trust Indenture Act. The
Guarantee Trustee, State Street Bank and Trust Company, will hold the Guarantee
for the benefit of the holders of the Preferred Securities. The following
summary of the material terms and provisions of the Guarantee does not purport
to be complete and is subject to, and qualified in its entirety by reference to,
all of the provisions of the Guarantee and the Trust Indenture Act. Wherever
particular defined terms of the Guarantee are referred to, but not defined
herein, such defined terms are incorporated herein by reference. The form of the
Guarantee has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part.
 
GENERAL
 
    The Company will, pursuant to the Guarantee, irrevocably agree to pay in
full on a subordinated basis, to the extent set forth therein, the Guarantee
Payments (as defined herein) to the holders of the Preferred Securities, as and
when due, regardless of any defense, right of set-off or counterclaim that IUB
Trust may have or assert other than the defense of payment. The following
payments with respect to the Preferred Securities, to the extent not paid by or
on behalf of IUB Trust (the "Guarantee Payments"), will be subject to the
Guarantee: (i) any accrued and unpaid Distributions required to be paid on the
Preferred Securities, to the extent that IUB Trust has funds available therefor
at such time, (ii) the Redemption Price with
 
                                       87
<PAGE>
respect to any Preferred Securities called for redemption to the extent that IUB
Trust has funds available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution, winding up or liquidation of IUB Trust (other than in
connection with the distribution of Subordinated Debentures to the holders of
Preferred Securities or a redemption of all of the Preferred Securities), the
lesser of (a) the amount of the Liquidation Distribution, to the extent IUB
Trust has funds available therefor at such time, and (b) the amount of assets of
IUB Trust remaining available for distribution to holders of Preferred
Securities in liquidation of IUB Trust. The obligation of the Company to make a
Guarantee Payment may be satisfied by direct payment of the required amounts by
the Company to the holders of the Preferred Securities or by causing IUB Trust
to pay such amounts to such holders.
 
    The Guarantee will not apply to any payment of Distributions except to the
extent IUB Trust has funds available therefor. If the Company does not make
interest payments on the Subordinated Debentures held by IUB Trust, IUB Trust
will not pay Distributions on the Preferred Securities and will not have funds
legally available therefor.
 
STATUS OF THE GUARANTEE
 
    The Guarantee will constitute an unsecured obligation of the Company and
will rank subordinate and junior in right of payment to all Senior Debt,
Subordinated Debt and Additional Senior Obligations of the Company in the same
manner as the Subordinated Debentures. The Guarantee does not place a limitation
on the amount of additional Senior Debt, Subordinated Debt or Additional Senior
Obligations that may be incurred by the Company. The Company expects from time
to time to incur additional indebtedness constituting Senior Debt, Subordinated
Debt and Additional Senior Obligations.
 
    The Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the Company to enforce its rights under the Guarantee without first instituting
a legal proceeding against any other Person). The Guarantee will not be
discharged except by payment of the Guarantee Payments in full to the extent not
paid by IUB Trust or upon distribution of the Subordinated Debentures to the
holders of the Preferred Securities. Because the Company is a holding company,
the right of the Company to participate in any distribution of assets of any
Subsidiary Bank upon such Subsidiary Bank's liquidation or reorganization or
otherwise is subject to the prior claims of creditors of that Subsidiary Bank,
except to the extent the Company may itself be recognized as a creditor of that
Subsidiary Bank. The Company's obligations under the Guarantee, therefore, will
be effectively subordinated to all existing and future liabilities of the
Company subsidiaries, and claimants should look only to the assets of the
Company for payments thereunder.
 
AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes which do not materially adversely affect
the rights of holders of the Preferred Securities (in which case no vote will be
required), the Guarantee may not be amended without the prior approval of the
holders of not less than a majority of the aggregate Liquidation Amount of the
outstanding Preferred Securities. See "Description of the Preferred
Securities--Voting Rights; Amendment of Trust Agreement." All guarantees and
agreements contained in the Guarantee will bind the successors, assigns,
receivers, trustees and representatives of the Company and will inure to the
benefit of the holders of the Preferred Securities then outstanding.
 
EVENTS OF DEFAULT
 
    An event of default under the Guarantee will occur upon the failure of the
Company to perform any of its payment or other obligations thereunder. The
holders of not less than a majority in aggregate Liquidation Amount of the
Preferred 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 the Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under the Guarantee.
 
                                       88
<PAGE>
    Any holder of Preferred Securities may institute a legal proceeding directly
against the Company to enforce its rights under the Guarantee without first
instituting a legal proceeding against IUB Trust, the Guarantee Trustee or any
other Person.
 
    The Company, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not the Company is in compliance with all
the conditions and covenants applicable to it under the Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
    The Guarantee Trustee, other than during the occurrence and continuance of a
default by the Company in performance of the Guarantee, undertakes to perform
only such duties as are specifically set forth in the Guarantee and, after
default with respect to the Guarantee, 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 such provisions, the Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by the Guarantee at the
request of any holder of any Preferred Securities, unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred thereby.
 
TERMINATION OF THE GUARANTEE
 
    The Guarantee will terminate and be of no further force and effect upon (a)
full payment of the Redemption Price of the Preferred Securities, (b) full
payment of the amounts payable upon liquidation of IUB Trust, or (c)
distribution of the Subordinated Debentures to the holders of the Preferred
Securities. The Guarantee will continue to be effective or will be reinstated,
as the case may be, if at any time any holder of the Preferred Securities must
restore payment of any sums paid under such Preferred Securities or the
Guarantee. Governing Law
 
    The Guarantee will be governed by and construed in accordance with the laws
of the State of Indiana.
 
                               EXPENSE AGREEMENT
 
    The Company will, pursuant to the Agreement as to Expenses and Liabilities
entered into by it under the Trust Agreement (the "Expense Agreement"),
irrevocably and unconditionally guarantee to each person or entity to whom IUB
Trust becomes indebted or liable, the full payment of any costs, expenses or
liabilities of IUB Trust, other than obligations of IUB Trust to pay to the
holders of the Preferred Securities or other similar interests in IUB Trust of
the amounts due such holders pursuant to the terms of the Preferred Securities
or such other similar interests, as the case may be. Third party creditors of
IUB Trust may proceed directly against the Company under the Expense Agreement,
regardless of whether such creditors had notice of the Expense Agreement.
 
         RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE SUBORDINATED
                          DEBENTURES AND THE GUARANTEE
 
FULL AND UNCONDITIONAL GUARANTEE
 
    Payments of Distributions and other amounts due on the Preferred Securities
(to the extent IUB Trust has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Company as and to the extent
set forth under "Description of the Guarantee." The Company and IUB Trust
believe that, taken together, the obligations of the Company under the
Subordinated Debentures, the Indenture, the Trust Agreement, the Expense
Agreement, and the Guarantee provide, in the aggregate, a full, irrevocable and
unconditional guarantee, on a subordinated basis, of payment of Distributions
and other amounts due on the Preferred Securities. No single document standing
alone or operating in conjunction with fewer than all of the other documents
constitutes such guarantee. It is only the combined operation of these documents
that has the effect of providing a full, irrevocable and unconditional guarantee
of the obligations of IUB Trust under the Preferred Securities. If and to the
extent that the Company does not
 
                                       89
<PAGE>
make payments on the Subordinated Debentures, IUB Trust will not pay
Distributions or other amounts due on the Preferred Securities. The Guarantee
does not cover payment of Distributions when IUB Trust does not have sufficient
funds to pay such Distributions. In such event, the remedy of a holder of
Preferred Securities is to institute a legal proceeding directly against the
Company for enforcement of payment of such Distributions to such holder. The
obligations of the Company under the Guarantee are subordinate and junior in
right of payment to all Senior Debt, Subordinated Debt and Additional Senior
Obligations of the Company.
 
SUFFICIENCY OF PAYMENTS
 
    As long as payments of interest and other payments are made when due on the
Subordinated Debentures, such payments will be sufficient to cover Distributions
and other payments due on the Preferred Securities, primarily because (i) the
aggregate principal amount of the Subordinated Debentures will be equal to the
sum of the aggregate stated Liquidation Amount of the Trust Securities, (ii) the
interest rate and interest and other payment dates on the Subordinated
Debentures will match the Distribution rate and Distribution and other payment
dates for the Preferred Securities, (iii) the Company will pay for all and any
costs, expenses and liabilities of IUB Trust (except the obligations of IUB
Trust to holders of the Preferred Securities), and (iv) the Trust Agreement
further provides that IUB Trust will not engage in any activity that is not
consistent with the limited purposes of IUB Trust.
 
ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES
 
    A holder of any Preferred Security may institute a legal proceeding directly
against the Company to enforce its rights under the Guarantee without first
instituting a legal proceeding against the Guarantee Trustee, IUB Trust or any
other Person. A default or event of default under any Senior Debt, Subordinated
Debt or Additional Senior Obligations of the Company would not constitute a
default or Event of Default. In the event, however, of payment defaults under,
or acceleration of, Senior Debt, Subordinated Debt or Additional Senior
Obligations of the Company, the subordination provisions of the Indenture
provide that no payments may be made in respect of the Subordinated Debentures
until such Senior Debt, Subordinated Debt or Additional Senior Obligations has
been paid in full or any payment default thereunder has been cured or waived.
Failure to make required payments on the Subordinated Debentures would
constitute an Event of Default.
 
LIMITED PURPOSE OF IUB TRUST
 
    The Preferred Securities evidence a preferred undivided beneficial interest
in the assets of IUB Trust. IUB Trust exists for the exclusive purposes of (i)
issuing the Trust Securities representing undivided beneficial interests in the
assets of IUB Trust, (ii) investing the gross proceeds of the Trust Securities
in the Subordinated Debentures issued by the Company, and (iii) engaging in only
those other activities necessary, advisable, or incidental thereto. A principal
difference between the rights of a holder of a Preferred Security and the rights
of a holder of a Subordinated Debenture is that a holder of a Subordinated
Debenture is entitled to receive from the Company the principal amount of and
interest accrued on Subordinated Debentures held, while a holder of Preferred
Securities is entitled to receive Distributions from IUB Trust (or from the
Company under the Guarantee) if and to the extent IUB Trust has funds available
for the payment of such Distributions.
 
RIGHTS UPON TERMINATION
 
    Upon any voluntary or involuntary termination, winding-up or liquidation of
IUB Trust involving the liquidation of the Subordinated Debentures, the holders
of the Preferred Securities will be entitled to receive, out of assets held by
IUB Trust, the Liquidation Distribution in cash. See "Description of the
Preferred Securities--Liquidation Distribution upon Termination." Upon any
voluntary or involuntary
 
                                       90
<PAGE>
liquidation or bankruptcy of the Company, the Property Trustee, as holder of the
Subordinated Debentures, would be a subordinated creditor of the Company,
subordinated in right of payment to all Senior Debt, Subordinated Debt and
Additional Senior Obligations of the Company (as set forth in the Indenture),
but entitled to receive payment in full of principal and interest before any
shareholders of the Company receive payments or distributions. Since the Company
is the guarantor under the Guarantee and has agreed to pay for all costs,
expenses and liabilities of IUB Trust (other than the obligations of IUB Trust
to the holders of its Preferred Securities), the positions of a holder of the
Preferred Securities and a holder of the Subordinated Debentures relative to
other creditors and to shareholders of the Company in the event of liquidation
or bankruptcy of the Company are expected to be substantially the same.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
    The following is a summary of the material United States Federal income tax
considerations that may be relevant to the purchasers of Preferred Securities
which has been passed upon by Greenebaum Doll & McDonald, PLLC, special counsel
to the Company and IUB Trust insofar as it relates to matters of law and legal
conclusions. The conclusions expressed herein are based upon current provisions
of the Internal Revenue Code of 1986, as amended (the "Code"), regulations
thereunder and current administrative rulings and court decisions, all of which
are subject to change at any time, with possible retroactive effect. Subsequent
changes may cause tax consequences to vary substantially from the consequences
described below. See "Possible Changes in Tax Laws." Furthermore, the
authorities on which the following summary is based are subject to various
interpretations, and it is therefore possible that the United States Federal
income tax treatment of the purchase, ownership, and disposition of Preferred
Securities may differ from the treatment described below.
 
    No attempt has been made in the following discussion to comment on all
United States Federal income tax matters affecting purchasers of Preferred
Securities. Moreover, the discussion generally focuses on holders of Preferred
Securities who are individual citizens or residents of the United States and who
acquire Preferred Securities on their original issue at their offering price and
hold Preferred Securities as capital assets. The discussion has only limited
application to dealers in securities, corporations, estates, trusts or
nonresident aliens and does not address all the tax consequences that may be
relevant to holders who may be subject to special tax treatment, such as, for
example, banks, thrifts, real estate investment trusts, regulated investment
companies, insurance companies, dealers in securities or currencies, tax-exempt
investors, or persons that will hold the Preferred Securities as a position in a
"straddle," as part of a "synthetic security" or "hedge," as part of a
"conversion transaction" or other integrated investment, or as other than a
capital asset. The following summary also does not address the tax consequences
to persons that have a functional currency other than the U.S. dollar or the tax
consequences to shareholders, partners or beneficiaries of a holder of Preferred
Securities. Further, it 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 be applicable to the Preferred Securities.
 
    Each prospective investor should consult, and should rely exclusively on,
such investor's own tax advisors in analyzing the federal, state, local and
foreign tax consequences of the purchase, ownership or disposition of Preferred
Securities.
 
CLASSIFICATION OF THE SUBORDINATED DEBENTURES
 
    The Company intends to take the position that the Subordinated Debentures
will be classified for United States Federal income tax purposes as indebtedness
of the Company under current law and, by acceptance of a Preferred Security,
each holder covenants to treat the Subordinated Debentures as indebtedness and
the Preferred Securities as evidence of an indirect beneficial ownership
interest in the
 
                                       91
<PAGE>
Subordinated Debentures. No assurance can be given, however, that such position
of the Company will not be challenged by the Internal Revenue Service or, if
challenged, that such a challenge will not be successful. The remainder of this
discussion assumes that the Subordinated Debentures will be classified for
United States Federal income tax purposes as indebtedness of the Company.
 
CLASSIFICATION OF IUB TRUST
 
    Under current law and assuming full compliance with the terms of the Trust
Agreement and Indenture (and certain other documents described herein), IUB
Trust will be classified for United States Federal income tax purposes as a
grantor trust and not as an association taxable as a corporation. Accordingly,
for United States Federal income tax purposes, each holder of Preferred
Securities generally will be treated as owning an undivided beneficial interest
in the Subordinated Debentures, and each holder will be required to include in
its return any income, gain, loss or expense with respect to its allocable share
of the Subordinated Debentures whether or not cash is actually distributed to
such holder.
 
    Because income on the Preferred Securities will constitute interest income
for United States Federal income tax purposes, corporate holders of Preferred
Securities will not be entitled to claim a dividends received deduction in
respect of such income.
 
POTENTIAL EXTENSION OF INTEREST PAYMENT PERIOD AND ORIGINAL ISSUE DISCOUNT
 
    The Company's option to extend the interest payment period on the
Subordinated Debentures may cause the indebtedness to be issued with original
issue discount ("OID"). Under Treasury regulations (the "Regulations"),a
contingency that stated interest will not be timely paid that is "remote" will
be ignored in determining whether such debt instrument is issued with OID.
Because the exercise by the Company of its option to defer the payment of stated
interest on the Subordinated Debentures would prevent the Company from declaring
dividends on any class of equity, the Company believes that the likelihood of
its exercising the option is "remote" withing the meaning of the Regulations. As
a result, the Company intends to take the position that the Subordinated
Debentures will not be deemed to be issued with OID at the time of their initial
issuance. If this position is sustained, a holder of the Preferred Securities
should include in gross income such holder's allocable share of interest on the
Subordinated Debentures.
 
    There can be no assurance, however, that the Internal Revenue Service will
not successfully contest the Company's position. If the Internal Revenue Service
were successful in such a contention, then all of the stated interest payments
on the Subordinated Debentures would be treated as OID. In such case, the
holders of the Preferred Securities would be required to include OID in income
on an economic accrual basis regardless of whether any interest is actually paid
or their method of tax accounting, but will not be required to report actual
payments of interest as taxable income.
 
    If the Company's position that there is no OID initially is upheld, but the
Company exercises its option to defer any payment of interest, the Subordinated
Debentures would at the time of such exercise be treated as issued with OID, and
all stated interest thereafter payable on the Subordinated Debentures would be
treated as OID. In such event, the holders of the Preferred Securities would be
required to account for the OID as stated in the immediately preceding
paragraph. Consequently, a holder of Preferred Securities would be required to
include in gross income OID even though the Company would not make any actual
interest payments during an Extension Period.
 
MARKET DISCOUNT AND ACQUISITION PREMIUM
 
    Holders of Preferred Securities other than a holder who purchased the
Preferred Securities upon original issuance may be considered to have acquired
their undivided interests in the Subordinated Debentures with "market discount"
or "acquisition premium" as such phrases are defined for United States Federal
income tax purposes. Such holders are advised to consult their tax advisors as
to the income tax consequences of the acquisition, ownership and disposition of
the Preferred Securities.
 
                                       92
<PAGE>
RECEIPT OF SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF IUB TRUST
 
    Under certain circumstances, as described under "Description of the
Preferred Securities--Redemption or Exchange" and "--Liquidation Distribution
upon Termination," the Subordinated Debentures may be distributed to holders of
Preferred Securities upon a liquidation of IUB Trust. Under current United
States Federal income tax law, such a distribution would be treated as a
nontaxable event to each such holder and would result in such holder having an
aggregate tax basis in the Subordinated Debentures received in the liquidation
equal to such holder's aggregate tax basis in the Preferred Securities
immediately before the distribution. A holder's holding period in the
Subordinated Debentures so received in liquidation of IUB Trust would include
the period for which such holder held the Preferred Securities.
 
    If, however, a Tax Event occurs which results in IUB Trust being treated as
an association taxable as a corporation, the distribution would likely
constitute a taxable event to IUB Trust and holders of the Preferred Securities.
Each holder of a Preferred Security would recognize gain or loss if such holder
exchanged the Preferred Securities for the Subordinated Debentures it received
upon liquidation of IUB Trust. Under certain circumstances described herein, the
Subordinated Debentures may be redeemed for cash and the proceeds of such
redemption distributed to holders in redemption of their Preferred Securities.
Under current law, such a redemption would, for United States Federal income tax
purposes, constitute a taxable disposition of the redeemed Preferred Securities,
and a holder would recognize gain or loss as if the holder sold such Preferred
Securities for cash. See "Description of the Preferred Securities-- Redemption
or Exchange" and "--Liquidation Distribution upon Termination."
 
DISPOSITION OF PREFERRED SECURITIES
 
    Upon the sale of the Preferred Securities, a holder will recognize a gain or
loss in an amount equal to the difference between its adjusted tax basis in the
Preferred Securities and the amount realized on the sale of such Preferred
Securities (except to the extent of any amount received in respect of accrued
but unpaid interest not previously included in income). Assuming that the
Company's position that there is no OID initially is upheld, and that the
Company does not exercise its payment of interest on the Subordinated
Debentures, a holder's adjusted tax basis for the Preferred Securities generally
will be its initial purchase price increased by OID previously includible in the
holder's gross income to the date of disposition and decreased by payments
received on the Preferred Securities, since the date the Preferred Securities
were deemed to have OID, in respect of OID to the date of disposition. Such gain
or loss generally will be a capital gain or loss. As a result of the recently
enacted Taxpayer Relief Act of 1997, in the case of noncorporate taxpayers, the
tax rates applicable to capital gains from the disposition of Preferred
Securities generally will vary depending upon whether, at the time of
disposition, the Preferred Securities have been held for more than twelve months
or more than eighteen months.
 
    The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Debentures. A holder that disposes of its Preferred Securities
between record dates for payment of distributions thereon will be required to
include as ordinary income either OID (if applicable) or accrued but unpaid
interest on the Subordinated Debentures through the date of disposition. To the
extent that the amount realized on the sale is less than the holder's adjusted
tax basis, a holder will recognize a capital loss. Subject to certain limited
exceptions, capital losses cannot be applied to offset ordinary income for
United States Federal income tax purposes.
 
POSSIBLE CHANGES IN TAX LAWS
 
    Certain legislative proposals were made in 1996 and 1997 which were designed
to eliminate the ability of issuers of certain instruments from deducting
interest paid on those instruments. These proposals were not, however,
incorporated into the legislation recently enacted as the Taxpayer Relief Act of
1997. Nevertheless, there can be no assurance that other legislation enacted
after the date hereof will not adversely affect the ability of the Company to
deduct the interest payable on the Subordinated Debentures, and such legislation
could be retroactive in effect. Consequently, there can be no assurance that a
Tax Event will not occur. A Tax Event would permit the Company, upon approval of
the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve, to cause a redemption
 
                                       93
<PAGE>
of the Preferred Securities before, as well as after, December 31, 2002. See
"Description of the Subordinated Debentures--Redemption" and "Description of the
Preferred Securities--Redemption--Tax Event Redemption, Capital Treatment Event
Redemption or Investment Company Event Redemption."
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    The amount of OID accrued on the Preferred Securities held of record by
individual citizens or residents of the United States, or certain trusts,
estates, and partnerships, will be reported to the Internal Revenue Service on
Forms 1099, which forms should be mailed to such holders of Preferred Securities
by January 31 following each calendar year. Payments made on, and proceeds from
the sale of, the Preferred Securities may be subject to a "backup" withholding
tax (currently at 31%) unless the holder complies with certain identification
and other requirements. Any amounts withheld under the backup withholding rules
will be allowed as a credit against the holder's United States Federal income
tax liability, provided the required information is provided to the Internal
Revenue Service.
 
    THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON THE
PARTICULAR SITUATION OF A HOLDER OF PREFERRED SECURITIES. HOLDERS OF PREFERRED
SECURITIES SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE PREFERRED
SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER
TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER
TAX LAWS.
 
                              ERISA CONSIDERATIONS
 
    Employee benefit plans that are subject to the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), or Section 4975 of the Code
("Plans"), generally may purchase Preferred Securities, subject to the investing
fiduciary's determination that the investment in Preferred Securities satisfies
ERISA's fiduciary standards and other requirements applicable to investments by
the Plan.
 
    In any case, the Company and/or any of its affiliates may be considered a
"party in interest" (within the meaning of ERISA) or a "disqualified person"
(within the meaning of Section 4975 of the Code) with respect to certain plans
(generally, Plans maintained or sponsored by, or contributed to by, any such
persons with respect to which the Company or an affiliate is a fiduciary or
Plans for which the Company or an affiliate provides services). The acquisition
and ownership of Preferred Securities by a Plan (or by an individual retirement
arrangement or other Plans described in Section 4975(e)(1) of the Code) with
respect to which the Company or any of its affiliates is considered a party in
interest or a disqualified person may constitute or result in a prohibited
transaction under ERISA or Section 4975 of the Code, unless such Preferred
Securities are acquired pursuant to and in accordance with an applicable
exemption.
 
    As a result, Plans with respect to which the Company or any of its
affiliates is a party in interest or a disqualified person should not acquire
Preferred Securities unless such Preferred Securities are acquired pursuant to
and in accordance with an applicable exemption. Any other Plans or other
entities whose assets include Plan assets subject to ERISA or Section 4975 of
the Code proposing to acquire Preferred Securities should consult with their own
counsel.
 
                                  UNDERWRITING
 
    Stifel, Nicolaus & Company, Incorporated (the "Underwriter") has agreed,
subject to the terms and conditions set forth in the Underwriting Agreement, the
form of which is filed as an exhibit to the Registration Statement of which this
Prospectus forms a part, to purchase 1,850,000 Preferred Securities from IUB
Trust. The Underwriter has agreed in the Underwriting Agreement, subject to the
terms and conditions set forth therein, to purchase all the Preferred Securities
offered hereby if any of the Preferred Securities are purchased.
 
                                       94
<PAGE>
    The Underwriter has advised IUB Trust that it proposes initially to offer
the Preferred Securities to the public at the public offering price set forth on
the cover page of this Prospectus, and to certain dealers at such price less a
concession not in excess of $         per Preferred Security. The Underwriter
may allow, and such dealers may reallow, a discount not in excess of
$         per Preferred Security to certain other dealers. After the initial
public offering, the public offering price, concession and discount may be
changed. Because the National Association of Securities Dealers, Inc. ("NASD")
is expected to view the Preferred Securities as interests in a direct
participation program, the offering of the Preferred Securities is being made in
compliance with the applicable provisions of Rule 2810 of the NASD's Conduct
Rules.
 
    In view of the fact that the proceeds of the sale of the Preferred
Securities will be used to purchase the Subordinated Debentures of the Company,
the Underwriting Agreement provides that the Company will pay as compensation to
the Underwriter for arranging the investment therein of such proceeds
$         per Preferred Security (or $         in the aggregate) for the account
of the Underwriter.
 
    IUB Trust has granted the Underwriter an option to purchase up to an
additional 277,500 Preferred Securities at the initial public offering price.
Such option, which expires 30 days from the date of this Prospectus, may be
exercised solely to cover over-allotments. To the extent that the Underwriter
exercises its option to purchase additional Preferred Securities, IUB Trust will
issue and sell to the Company additional Common Securities in an aggregate
Liquidation Amount equal to at least 3% of the total capital of IUB Trust and
the Company will issue and sell to IUB Trust Subordinated Debentures in an
aggregate principal amount equal to the aggregate Liquidation Amount of the
additional Preferred Securities being purchased pursuant to the option.
 
    Application has been made to have the Preferred Securities approved for
quotation on the Nasdaq National Market. The Underwriter has advised IUB Trust
that it presently intends to make a market in the Preferred Securities after the
commencement of trading on the Nasdaq National Market, but no assurances can be
made as to the liquidity of such Preferred Securities or that an active and
liquid trading market will develop or, if developed, that it will continue. The
offering price and distribution rate have been determined by negotiations among
representatives of the Company and the Underwriter, and the offering price of
the Preferred Securities may not be indicative of the market price following the
offering. The Underwriter will have no obligation to make a market in the
Preferred Securities, however, and may cease market-making activities, if
commenced, at any time.
 
    IUB Trust and the Company have agreed to indemnify the Underwriter against,
or contribute to payments that the Underwriter may be required to make in
respect of, certain liabilities, including liabilities under the Securities Act.
 
    In connection with the offering of the Preferred Securities, the Underwriter
and any selling group members and their respective affiliates may engage in
transactions effected in accordance with Rule 104 of the Commission's Regulation
M that are intended to stabilize, maintain or otherwise affect the market price
of the Preferred Securities. Such transactions may include over-allotment
transactions in which the Underwriter creates a short position for its own
account by selling more Preferred Securities than it is committed to purchase
from IUB Trust. In such case, to cover all or part of the short position, the
Underwriter may exercise the over-allotment option described above or may
purchase Preferred Securities in the open market following completion of the
initial offering of the Preferred Securities. The Underwriter also may engage in
stabilizing transactions in which it bids for, and purchases, Preferred
Securities at a level above that which might otherwise prevail in the open
market for the purpose of preventing or retarding a decline in the market price
of the Preferred Securities. The Underwriter also may reclaim any selling
concessions allowed to a dealer if the Underwriter repurchases Preferred
Securities distributed by that dealer. Any of the foregoing transactions may
result in the maintenance of a price for the Preferred Securities at a level
above that which might otherwise prevail in the open market. Neither the Company
nor the Underwriter makes any representation or prediction as to the direction
or magnitude of any effect
 
                                       95
<PAGE>
that the transactions described above may have on the price of the Preferred
Securities. The Underwriter is not required to engage in any of the foregoing
transactions and, if commenced, such transactions may be discontinued at any
time without notice.
 
MISCELLANEOUS
 
    The Company has agreed, pursuant to the Indenture, for so long as Trust
Securities remain outstanding, (i) to maintain directly or indirectly 100%
ownership of the Common Securities of IUB Trust (provided that certain
successors which are permitted pursuant to the Indenture may succeed to the
Company's ownership of the Common Securities), (ii) not to voluntarily
terminate, wind up or liquidate IUB Trust, except upon prior approval of the
Federal Reserve if then so required under applicable capital guidelines or
policies of the Federal Reserve, and (a) in connection with a distribution of
Subordinated Debentures to the holders of the Preferred Securities in
liquidation of IUB Trust, or (b) in connection with certain mergers,
consolidations or amalgamations permitted by the Trust Agreement, and (iii) to
use its reasonable efforts, consistent with the terms and provisions of the
Trust Agreement, to cause IUB Trust to remain classified as a grantor trust and
not as an association taxable as a corporation for United States Federal income
tax purposes.
 
                             VALIDITY OF SECURITIES

Securities, the enforceability of the Trust Agreement and the formation of IUB
Trust will be passed upon by Richards, Layton & Finger, special Delaware counsel

Trust, including the validity of the Guarantee and the Subordinated Debentures,
will be passed upon for the Company and IUB Trust by David W. Harper, Esq.,
Louisville, Kentucky, counsel to the Company and IUB Trust, and Greenebaum Doll
& McDonald PLLC, Louisville, Kentucky, special counsel to the Company and IUB
Trust. Certain legal matters will be passed upon for the Underwriter by Bryan

Underwriter will rely on the opinion of Richards, Layton & Finger as to matters
of Delaware law. Certain matters relating to United States Federal income tax
considerations will be passed upon for the Company by Greenebaum Doll & McDonald
PLLC.

    No separate financial statements of IUB Trust have been included herein. The
Company does not consider that such financial statements would be material to
the holders of the Preferred Securities because (i) all of the voting securities
of IUB Trust will be owned by the Company, a reporting company under the
Exchange Act, (ii) IUB Trust has no independent operations and exists for the
sole purpose of issuing securities representing undivided beneficial interest in
the assets of IUB Trust and investing the proceeds thereof in the Subordinated
Debentures issued by the Company, and (iii) the obligations of the Company
described herein to provide certain indemnities in respect of and be responsible
for certain costs, expenses, debts and liabilities of IUB Trust under the
Indenture and pursuant to the Trust Agreement, the guarantee issued by the
Company with respect to the Preferred Securities, and the Subordinated
Debentures purchased by IUB Trust and the related Indenture, taken together,
constitute, in the belief of the Company and IUB Trust, a full and unconditional
guarantee of payments due on the Preferred Securities. See "Description of the
Subordinated Debentures" and "Description of the Guarantee".
 
    IUB Trust is not currently subject to the information reporting requirements
of the Exchange Act. IUB Trust will become subject to such requirements upon the
effectiveness of the Registration Statement, although it intends to seek and
expects to receive an exemption therefrom.

           COMPANY NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
 
                      (TABLE DOLLARS AMOUNTS IN THOUSANDS)
 
NOTE 1.
 
    The significant accounting policies followed by Indiana United Bancorp
("Company") and its subsidiaries, Union Bank and Trust Company of Indiana
("Union Bank") and Regional Federal Savings Bank ("Regional Bank") for interim
financial reporting are consistent with the accounting policies followed for
annual financial reporting. All adjustments, consisting only of normal recurring
adjustments, which in the opinion of management are necessary for a fair
presentation of the results for the periods reported, have been included in the
accompanying consolidated financial statements. The results of operations for
the nine months ended September 30, 1997 are not necessarily indicative of those
expected for the remainder of the year.
 
NOTE 2:
 
    On October 8, 1997, the Company signed a definitive agreement to acquire
P.T.C. Bancorp ("PTC"), Brookville, Indiana in a proposed transaction viewed as
a merger of equals with the combined entity retaining the name of Indiana United
Bancorp. The definitive agreement provides that PTC shareholders (including
option holders) will receive 1.075 shares of Company common stock in exchange
for each share owned or option held of PTC common stock.
 
    The consolidated company will hold assets totaling almost $650 million and
will have market capitalization of more than $100 million based upon current
market values. Upon completion of the merger, Indiana United Bancorp will
operate 29 offices in 12 counties throughout the eastern and southern regions of
Indiana.
 
    The proposed transaction is subject to various regulatory approvals and the
approval of the shareholders of both organizations. It is expected that the
transaction will be accounted for as a "pooling of interests". Although the
Company anticipates that the merger will be consummated during the first quarter
of 1998, there can be no assurance that the transaction will be completed.
 
NOTE 3:
 
    The Company is in process of preparing a registration statement to be filed
with the Securities and Exchange Commission ("SEC") for the purpose of issuing
$18,500,000 Cumulative Trust Preferred Securities ("Preferred Securities"). The
Preferred Securities will represent undivided beneficial interests in the assets
of a statutory business trust being established by the Company. The Company will
acquire all the common securities of the business trust. The assets of the
business trust will consist solely of Subordinated Debentures issued by the
Company and purchased with the proceeds from the issuance of the Preferred
Securities. The Company will guarantee the payment of the Preferred Securities.
 
    Under the risk-based guideline established by the Federal Reserve, a portion
of the proceeds from the sale of Preferred Securities are expected to qualify as
Tier 1 or core capital. These guidelines provide that the Preferred Securities
cannot exceed 25% of total Tier 1 capital of the Company, however; the amount in
excess of the 25% limitation will constitute Tier 2, or supplementary capital.
 
    For financial reporting purposes, the business trust will be treated as a
wholly owned subsidiary of the Company and the accounts of the business trust
will be included in the consolidated financial statements of the Company. The
Preferred Securities will be presented as a separate line item in the
consolidated balance sheet and interest on the Preferred Securities will be
recorded as an expense in the consolidated statement of income. In addition,
appropriate disclosures in the footnotes to the consolidated financial
statements describing the Preferred Securities, Subordinated Debentures,
business trust and the guarantee will be presented.

                          INDEPENDENT AUDITOR'S REPORT
 
To the Shareholders and
Board of Directors
Indiana United Bancorp
Greensburg, Indiana
 
    We have audited the consolidated balance sheet of Indiana United Bancorp and
subsidiaries as of December 31, 1996 and 1995, and the related consolidated
statements of income, changes in shareholders' equity and cash flows for each of
the three years in the period ended December 31, 1996. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements described above
present fairly, in all material respects, the consolidated financial position of
Indiana United Bancorp and subsidiaries as of December 31, 1996 and 1995, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1996, in conformity with generally accepted
accounting principles.
 
    As discussed in the notes to the financial statements, the Company changed
its method of accounting for investments in securities in 1994.

                      (TABLE DOLLAR AMOUNTS IN THOUSANDS)
 
    NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    The accounting and reporting policies of Indiana United Bancorp ("Company"),
and its wholly owned subsidiaries, ("Banks"), conform to generally accepted
accounting principles and reporting practices followed by the banking industry.
The more significant of the policies are described below.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    The Company is a bank holding company whose principal activity is the
ownership and management of the Banks. Union Bank and Trust Company of Indiana
("Union Bank") headquartered in Greensburg, Indiana operates under a state
charter and is subject to regulation by the Indiana Department of Financial
Institutions ("DFI") and the Federal Deposit Insurance Corporation ("FDIC").
Regional Federal Savings Bank ("Regional Bank"), headquartered in New Albany,
Indiana is a federally-chartered thrift and is subject to regulation by the
Office of Thrift Supervision ("OTS") and the FDIC.
 
    The Banks generate commercial, mortgage and consumer loans and receive
deposits from customers located primarily in Decatur, Floyd, Clark and Jay
Counties, Indiana, and surrounding counties. The Banks' loans are generally
secured by specific items of collateral including real property, consumer assets
and business assets. Although the Banks have diversified loan portfolios, a
substantial portion of their debtors' ability to honor their contracts is
dependent upon economic conditions in the agricultural industry.
 
    CONSOLIDATION--The consolidated financial statements include the accounts of
the Company and the Banks after elimination of all material intercompany
transactions and accounts.
 
    INVESTMENT SECURITIES--Debt securities are classified as held to maturity
("HTM") when the Company has the positive intent and ability to hold the
securities to maturity. Securities HTM are carried at amortized cost.
 
    Debt securities not classified as HTM are classified as available for sale
("AFS"). Securities AFS are carried at fair value with unrealized gains and
losses reported separately through shareholders' equity, net of tax.
 
    Amortization of premiums and accretion of discounts are recorded as interest
income from securities. Realized gains and losses are recorded as net security
gains (losses). Gains and losses on sales of securities are determined on the
specific-identification method.
 
    At January 1, 1994, investment securities with an approximate carrying value
of $125,081,000 were reclassified as AFS. This reclassification resulted in an
increase in total shareholders' equity, net of tax, of $846,177.
 
    LOANS are carried at the principal amount outstanding. Interest income is
accrued on the principal balances of loans. The accrual of interest on impaired
loans is discontinued when, in management's opinion, the borrower may be unable
to meet payments as they become due. When interest accrual is discontinued, all
unpaid accrued interest is reversed. Interest income is subsequently recognized
only to the extent cash payments are received unless such amounts are applied to
principal amounts outstanding. Certain loan fees and direct costs are being
deferred and amortized as an adjustment of yield on the loans.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                      (TABLE DOLLAR AMOUNTS IN THOUSANDS)
 
    PROVISION FOR LOAN LOSSES and the adequacy of the allowance for loan losses
are based on management's continuing review and evaluation of the loan
portfolio, current economic conditions, past loss experience and other pertinent
factors. Impaired loans are measured by the present value of expected cash
flows, or the fair value of the collateral of the loan, if collateral dependent.
 
    The determination of the adequacy of the allowance for loan losses is based
on estimates that are particularly susceptible to significant changes in the
economic environment and market conditions. Management believes that as of
December 31, 1996, the allowance for loan losses is adequate based on
information currently available. A worsening or protracted economic decline in
the area within which the Company operates would increase the likelihood of
additional losses due to credit and market risks and could create the need for
additional loss reserves.
 
    PREMISES AND EQUIPMENT are carried at cost net of accumulated depreciation.
Depreciation is computed using the straight-line method for premises and the
declining-balance method for equipment based principally on the estimated useful
lives of the assets. Maintenance and repairs are expensed as incurred while
major additions and improvements are capitalized. Gains and losses on
dispositions are included in current operations.
 
    FEDERAL HOME LOAN BANK STOCK is a required investment for institutions that
are members of the Federal Home Loan Bank ("FHLB") system. The required
investment in the common stock is based on a predetermined formula.
 
    FORECLOSED REAL ESTATE is carried at the lower of cost or fair value less
estimated selling costs. When foreclosed real estate is acquired, any required
adjustment is charged to the allowance for loan losses. All subsequent activity
is included in current operations.
 
    CORE DEPOSIT INTANGIBLES resulting from the value of the future stream of
income allocated to customer deposits acquired in acquisitions is being
amortized over a period of 15 years using accelerated methods.
 
    INCOME TAX in the consolidated statement of income includes deferred income
tax provisions or benefits for all significant temporary differences in
recognizing income and expenses for financial reporting and income tax purposes.
The Company files consolidated income tax returns with its subsidiaries.
 
    EARNINGS PER SHARE have been computed based upon the weighted average common
shares outstanding during each year.
 
    RESTRICTION ON CASH AND DUE FROM BANKS
 
    The Banks are required to maintain reserve funds in cash and/or on deposit
with the Federal Reserve Bank. The reserve required at December 31, 1996, was
$1,565,000.

    Long-term debt at December 31, 1996 consisted of a $5,000,000 secured term
loan. In January, 1992, the Company converted a line of credit to an $11,200,000
six-year secured term loan. Interest is payable quarterly and was at the
lender's base rate through June 30, 1995. Commencing July 1, 1995, the interest
rate converted to the lender's base rate, less .25%. Principal payments are due
semiannually. The loan is secured by all stock of the Banks and the loan
agreement contains restrictions on debt, guarantees and mergers, in addition to
other affirmative and negative covenants.
 
    A principal payment of $375,000 is due June 30, 1997 with the remaining loan
balance due December 31, 1997. Management intends to refinance all or a portion
of the remaining balance during 1997.

income for tax purposes only, which income would be subject to the then-current
corporate income tax rate. The unrecorded deferred income tax liability on the
above amount at December 31, 1996 was approximately $735,000.
 
    COMMITMENTS AND CONTINGENT LIABILITIES
 
    In the normal course of business there are outstanding commitments and
contingent liabilities, such as commitments to extend credit and standby letters
of credit, which are not included in the accompanying financial statements. The
Banks' exposure to credit loss in the event of nonperformance by the other party
to the financial instruments for commitments to extend credit and standby
letters of credit is represented by the contractual or notional amount of those
instruments. The Banks use the same credit policies in making such commitments
as they do for instruments that are included in the consolidated balance sheet.
 
    Financial instruments whose contract amount represents credit risk as of
December 31 were as follows:

Standby letters of credit...............................................        222        155
</TABLE>
 
    Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee. Since many of the commitments are expected to expire
without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. Collateral held varies but may include
accounts receivable, inventory, property and equipment, and income-producing
commercial properties. Standby letters of credit are conditional commitments
issued by the Banks to guarantee the performance of a customer to a third party.
 
    The Company and Banks may from time to time be subject to claims and
lawsuits which arise primarily in the ordinary course of business. Management is
presently not aware of any such claims.
 
    PREFERRED SHARES
 
    In 1987, the Company issued 30,000 shares of no-par value, $100 stated
value, convertible preferred stock. The Company redeemed 20,000 shares of
preferred stock in 1996, 4,000 shares in 1995 and 3,000 shares in 1994. The
total redemption price was $2,000,000 in 1996, $400,000 in 1995 and $300,000 in
1994. For 1994 through 1996, cash dividends were paid at the rate of 6.34% per
annum.
 
    The Company's Articles of Incorporation permit the Board of Directors,
without further shareholder approval, to establish the relative rights,
designations, preferences and limitations or restrictions of the Company's
preferred stock prior to the issuance thereof.
 
    RESTRICTIONS ON DIVIDENDS
 
    Without prior approval, Union Bank is restricted by Indiana law and
regulations of the DFI, and the FDIC as to the maximum amount of dividends Union
Bank can pay to the parent in any calendar year to Union Bank's retained net
profits (as defined) for that year and the two preceding years.
 
    The OTS regulations provide that a savings bank which meets fully phased-in
1994 capital requirements and is subjected only to "normal supervision", such as
Regional Bank, may pay out 100% of net income to date over the calendar year and
50% of surplus capital existing at the beginning of the calendar

year without supervisory approval, but with 30 days prior notice to OTS. As a
result of limitations relating to tax bad debt deductions, Regional Bank's
nontaxable dividends to the Company are limited to an amount approximately equal
to net income commencing in 1997.
 
    At December 31, 1996, total shareholders' equity of the Banks was
$31,075,000 of which $29,504,000 was restricted or limited from dividend
distribution to the Company. As a practical matter, the Banks may restrict
dividends to a lesser amount because of the need to maintain an adequate capital
structure.
 
    REGULATORY CAPITAL
 
    The Company and Banks are subject to various regulatory capital requirements
administered by the federal banking agencies. Failure to meet minimum capital
requirements can initiate actions by the regulatory agencies that, if
undertaken, could have a material effect on the Company's financial statements.
Under capital adequacy guidelines and the regulatory framework for prompt
corrective action, the Company and Banks must meet specific capital guidelines
that involve quantitative measures of the Company's and Banks' assets,
liabilities, and certain off-balance-sheet items as calculated under regulatory
accounting practices. The Company's and Banks' capital amounts and
classification are also subject to qualitative judgments by the regulators about
components, risk weightings, and other factors.
 
    At December 31, 1996, management of the Company believes that it meets all
capital adequacy requirements to which it is subject. The most recent
notification from the regulatory agencies categorized the Banks as well
capitalized under the regulatory framework for prompt corrective action. There
have been no conditions or events since that notification that management
believes have changed this categorization.
 
    The Company's and Banks' actual and required capital amounts and ratios are
as follows:

    LOAN SERVICING
 
    Mortgage loans serviced for others are not included in the accompanying
consolidated balance sheet. The unpaid principal balances of mortgage loans
serviced for others totaled $2,960,000 and $2,302,000 at December 31, 1996 and
1995.
 
    EMPLOYEE BENEFIT PLANS
 
    The Company has a defined-contribution retirement plan in which
substantially all employees may participate. The Company matched employees'
contributions at the rate of $.70 for 1996, $.65 for 1995, and $.60 for 1994 for
each dollar contributed. In addition, the Company contributed 6.5% of total
compensation plus an additional 5.7% of each participant's compensation in
excess of $62,700 in 1996, $61,200 in 1995 and $60,600 in 1994. Expense for the
plan was $283,518 in 1996, $295,862 in 1995 and $273,053 in 1994.
 
    DEPOSIT INSURANCE EXPENSE
 
    Regional Bank's deposits are presently insured by the Savings Association
Insurance Fund ("SAIF"). A recapitalization plan for the SAIF was signed into
law on September 30, 1996, which provided for a special assessment on all
SAIF-insured institutions to enable the SAIF to achieve the required level of
reserves. The assessment of .0657% was based on March 31, 1995 deposits.
Regional Banks' special assessment totaled $545,000 before taxes, and was
charged against current income and included with deposit insurance expense.
 
    FAIR VALUES OF FINANCIAL INSTRUMENTS
 
    The following methods and assumptions were used to estimate the fair value
of each class of financial instrument:
 
    CASH AND CASH EQUIVALENTS--The fair value of cash and cash equivalents
approximates carrying value.
 
    SHORT-TERM INVESTMENTS--The fair value of short-term investments
approximates carrying value.
 
    SECURITIES--Fair values are based on quoted market prices.
 
    LOANS--For both short-term loans and variable-rate loans that reprice
frequently and with no significant change in credit risk, fair values are based
on carrying values. The fair value for other loans are estimated using
discounted cash flow analyses, using interest rates currently being offered for
loans with similar terms to borrowers of similar credit quality.
 
    INCOME RECEIVABLE/INTEREST PAYABLE--The fair value of these amounts
approximates carrying values.
 
    FHLB STOCK--Fair value of FHLB stock is based on the price at which it may
be resold to the FHLB.
 
    DEPOSITS--The fair values of non-interest-bearing, interest-bearing demand,
and savings accounts are equal to the amount payable on demand at the balance
sheet date. The carrying amounts for variable rate, fixed-term certificates of
deposit approximate their fair values at the balance sheet date. Fair values for
fixed-rate certificates of deposit are estimated using a discounted cash flow
calculation that applies interest rates currently being offered on certificates
to a schedule of aggregated expected monthly maturities on such time deposits.

                      (TABLE DOLLAR AMOUNTS IN THOUSANDS)
 
    SHORT-TERM BORROWINGS--The interest rates for short-term borrowings
approximate market rates, thus the fair value approximates carrying value.
 
    LONG-TERM DEBT--Long-term debt consists of an adjustable instrument tied to
a variable market interest rate. Fair value approximates carrying value.
 
    The estimated fair values of the Company's financial instruments are as
follows:

             PTC NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of PTC Bancorp
(the "Company") and its wholly owned subsidiary, Peoples Trust Company (the
"Bank"). All significant intercompany accounts and transactions have been
eliminated.
 
    These financial statements were prepared in accordance with the instructions
for Form 10-QSB and, therefore, do not include all of the disclosures necessary
for a complete presentation of financial position, results of operations and
cash flows in conformity with generally accepted accounting principles. These
financial statements have been prepared on a basis consistent with the annual
financial statements and include, in the opinion of management, all adjustments,
consisting of only normal recurring adjustments, necessary for a fair
presentation of the results of operations and financial position at the end of
and for the periods presented.
 
NOTE 2--PENDING ACCOUNTING CHANGES
 
    The Company does not expect the anticipated adoption of any newly issued
accounting standards to have a material impact on future operations or financial
position.
 
NOTE 3--EARNINGS PER SHARE
 
    Earnings per share have been computed based upon the weighted average number
of shares outstanding during the periods presented, adjusted for any stock
dividends. Common stock equivalents are not materially dilutive.
 
NOTE 4--PENDING BUSINESS COMBINATION
 
    On October 8, 1997, the Company agreed to merge with Indiana United Bancorp
("IUB"). IUB is a bank and thrift holding company located in Greensburg,
Indiana. Under terms of the agreement, each outstanding common share of PTC
Bancorp, including shares outstanding under option plans, will be converted into
1.075 common shares of IUB. The proposed transaction requires approval by
regulatory authorities and shareholders of both companies. The proposed
transaction is expected to be consummated during the first quarter of 1998. It
is expected to be accounted for as a pooling-of-interests.

Board of Directors and Shareholders
P.T.C. Bancorp
Brookville, Indiana
 
    We have audited the accompanying consolidated balance sheets of P.T.C.
Bancorp as of December 31, 1996 and 1995, and the related consolidated
statements of income, cash flows, and changes in shareholders' equity for the
years then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of P.T.C.
Bancorp as of December 31, 1996 and 1995, and the results of its operations and
its cash flows for the years then ended in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                           DECEMBER 31, 1996 AND 1995
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BASIS OF PRESENTATION:  The consolidated financial statements include the
accounts of P.T.C. Bancorp (Company) and its wholly-owned subsidiary, People's
Trust Company (Bank). All significant intercompany transactions have been
eliminated in consolidation.
 
    DESCRIPTION OF BUSINESS:  P.T.C. Bancorp generates mortgage, commercial, and
installment loans and receives deposits from customers located primarily in
southeastern Indiana. The majority of the Company's loans are secured by
specific items of collateral including business assets, consumer assets and real
property.
 
    USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS:  The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets, liabilities, revenues and expenses.
Actual results could differ from those estimates. Estimates that are more
susceptible to change in the near term include the allowance for loan losses and
fair values of certain securities.
 
    CASH AND CASH EQUIVALENTS:  Cash and cash equivalents include cash on hand,
amounts due from banks and federal funds sold. Generally, federal funds are sold
for one-day periods. The Company reports net cash flows for customer loan
transactions, deposit transactions, and deposits made with other institutions.
 
    SECURITIES:  Securities are classified by management at date of purchase as
available for sale or held to maturity. Securities classified as available for
sale are securities that might be sold in response to changes in interest rates,
changes in prepayment risk, or other similar factors, and which are carried at
fair value. The unrealized gain/(loss) on securities available for sale is
reflected as a separate component of shareholders' equity, net of tax.
Securities classified as held to maturity are securities that the Company has
both the ability and positive intent to hold to maturity and are carried at
amortized cost (cost adjusted for amortization of premium or accretion of
discounts). Interest income on securities is recognized using the level yield
basis. Gains and losses on sales of securities are computed on a specific
identification basis.
 
    LOANS HELD FOR SALE:  During the normal course of business, the Company
originates certain mortgage loans for the purpose of selling them in certain
secondary markets. These loans are carried at the lower of aggregate cost or
market value.
 
    LOANS:  Loans are reported at the principal balance outstanding, net of
deferred loan fees and costs, the allowance for loan losses, and charge-offs.
Interest income is reported on the interest method and includes amortization of
net deferred loan fees and costs over the loan term.
 
    Interest income is not reported when full loan repayment is in doubt,
typically when payments are past due over 90 days. Interest received on such
loans is recognized on the cash basis or reported as principal reductions.
 
    ALLOWANCE FOR LOAN LOSSES:  The allowance for loan losses is a valuation
allowance, increased by the provision for loan losses and decreased by
charge-offs less recoveries. Management estimates the allowance balance required
based on past loan loss experience, known and inherent risks in the portfolio,
information about specific borrower situations and estimated collateral values,
economic conditions, and other factors. Allocations of the allowance may be made
for specific loans, but the entire allowance is available for any loan that, in
management's judgment, should be charged-off.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                           DECEMBER 31, 1996 AND 1995
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Loan impairment is reported when full payment under the loan terms is not
expected. Impairment is evaluated in total for smaller-balance loans of similar
nature such as residential mortgage, consumer, and credit card loans, and on an
individual loan basis for other loans. If a loan is impaired, a portion of the
allowance is allocated so that the loan is reported, net, at the present value
of estimated future cash flows using the loan's existing rate. Loans are
evaluated for impairment when payments are delayed, typically 90 days or more,
or when the internal grading system indicates a doubtful classification.
 
    SERVICING RIGHTS:  Upon adopting Financial Accounting Standard No. 122 at
the start of 1996, servicing rights represent the allocated value of servicing
rights retained on loans sold. Servicing rights are expensed in proportion to,
and over the period of, estimated net servicing revenues. Impairment is
evaluated based on the fair value of the rights, using groupings of the
underlying loans as to interest rates and term. Any impairment of a grouping is
reported as a valuation allowance.
 
    PREMISES AND EQUIPMENT:  Premises and equipment are stated at cost, net of
accumulated depreciation. Depreciation is charged to operating expense over the
useful lives of assets and is computed on straight-line and accelerated methods.
Maintenance and repairs are charged to operations as incurred. Improvements are
capitalized and disposals are recorded in the year sold or abandoned.
 
    INTANGIBLE ASSETS:  Intangible assets consist of goodwill and core deposit
intangibles. Goodwill is being amortized on a straight-line method over fifteen
years. The core deposit is being amortized based on the estimated life of the
deposits assumed, which is ten years.
 
    STOCK OPTIONS:  Expenses for compensation under stock option plans is based
on APB Opinion 25, with expense reported only if options are granted below
market price at date of grant. Proforma disclosures of net income and earnings
per share as required by FASB Statement No. 123 are not presented, because the
fair value of options granted during 1996 and 1995 is not material.
 
    INCOME TAXES:  Deferred tax liabilities and assets are determined at each
balance sheet date. They are measured by applying enacted tax laws to future
amounts that will result from differences in the financial statement and tax
basis of assets and liabilities. Recognition of deferred tax assets is limited
by the establishment of a valuation reserve unless management concludes that
they are more likely than not going to result in future tax benefits to the
Company. Income tax expense is the amount paid for the current year income tax
liability plus or minus the change in deferred taxes.
 
    EARNINGS PER SHARE:  Earnings per share is based on the weighted average
common shares outstanding. The Company declared a 10 percent stock dividend in
November, 1995 and 1996. Earnings and dividend per share amounts have been
retroactively restated. Stock options are not materially dilutive for earnings
per share purposes.

other party to the financial guarantees is represented by the contractual
amounts of those instruments. The Company uses the same credit policy to make
such commitments as it uses for on-balance-sheet items.
 
    The contractual amount of these financial instruments are summarized as
follows:

Standby letters of credit......................................      2,349,000      2,111,000
</TABLE>
 
    The commitments to extend credit are agreements to lend to a customer as
long as there is no violation of any condition established under the contract.
Generally, such commitments are for no more than one year, and most are variable
rate contracts. These commitments are primarily credit card, overdraft
protection, and commercial lines of credit.
 
    Since many commitments expire without being used, the amounts do not
necessarily represent future cash commitments. Collateral obtained upon exercise
of the commitment is determined using management's credit evaluation of the
borrower, and may include accounts receivable, inventory, property, land and
other items.
 
    At December 31, 1996 and 1995, the Company was required by the Federal
Reserve to have $3,542,000 and $2,704,000 on deposit or as cash in hand. These
reserves do not earn interest.
 
NOTE 11 -- RELATED PARTY TRANSACTIONS
 
    Certain directors, officers and principal shareholders of the Company were
also customers of the Bank. The aggregate amount of loans to these persons
totaled $2,139,417 and $2,520,434 at December 31, 1996 and 1995.
 
    Related party deposits totaled $1,337,157 at year-end 1996.
 
NOTE 12 -- DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:
 
    CASH AND SHORT-TERM INVESTMENTS:  For those short-term instruments, the
carrying amount is a reasonable estimate of fair value.
 
    SECURITIES:  For securities, fair value equals quoted market price, if
available. If a quoted market price is not available, fair value is estimated
using quoted market prices for similar instruments.
 
    LOANS RECEIVABLE:  The fair value of loans is estimated by discounting
future cash flows using the current rates at which similar loans would be made
to borrowers with similar credit ratings and for the same remaining maturities.
 
    DEPOSIT LIABILITIES:  The fair value of demand deposits, savings accounts,
and certain money market deposits is the amount payable on demand at the
reporting date. The fair value of fixed-maturity

certificates of deposit is estimated using the rates currently offered for
deposits of similar remaining maturities.

this adjustable rate instrument.
 
    OFF-BALANCE SHEET ITEMS:  Carrying value is a reasonable estimate of fair
value. These instruments are short term in nature.

NOTE 13 -- REGULATORY MATTERS
 
    The Company and Bank are subject to regulatory capital requirements
administered by federal banking agencies. Capital adequacy guidelines and prompt
corrective action regulations involve quantitative measures of assets,
liabilities and certain off-balance-sheet items calculated under regulatory
accounting practices. Capital amounts and classifications are also subject to
qualitative judgments by regulators about components, risk weightings, and other
factors, and the regulators can lower classifications in certain cases. Failure
to meet various capital requirements can initiate regulatory action that could
have a direct material effect on the financial statements.

NOTE 13 -- REGULATORY MATTERS (CONTINUED)
    The prompt corrective action regulations provide five classifications,
including well capitalized, adequately capitalized, undercapitalized,
significantly undercapitalized, and critically undercapitalized, although these
terms are not used to represent overall financial condition. If adequately
capitalized, regulatory approval is required to accept brokered deposits. If
undercapitalized, capital distributions are limited, as is asset growth and
expansion, and plans for capital restoration are required. The minimum
requirements are:

NOTE 14 -- PENDING ACCOUNTING CHANGES
 
    Financial Accounting Standard No. 125, Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities, was issued by
the Financial Accounting Standards Board in 1996. It revises the accounting for
transfers of financial assets, such as loans and securities, and for
distinguishing between sales and secured borrowings. It is effective for some
transactions in 1997 and others in 1998. The effect on the financial statements
is not expected to be material.

    NOTES TO PRO FORMA COMBINED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE 1
 
    On October 8, 1997, the Company entered into a Merger Agreement to acquire
PTC and its subsidiary, Peoples Trust, in a stock-for-stock merger. The Merger
Agreement, which is subject to the approval of Company and PTC shareholders and
various banking regulatory authorities, provides that the Company will issue
1,136,417 shares of Company common stock to the shareholders of PTC in exchange
for all of the issued and outstanding shares of stock of PTC. The transaction is
expected to be accounted for as a pooling of interests.
 
    The Pro Forma Consolidated Balance Sheet as of September 30, 1997, and
Consolidated Statements of Income for the three years ended December 31, 1996
and the nine months ended September 30, 1997 combine the historical consolidated
financial statements of the Company and PTC and are presented as if the Merger
had occurred on January 1, 1994, 1995, 1996 and 1997, after giving effect to the
pro forma adjustments described in the accompanying notes. In addition, the Pro
Forma Balance Sheet as of September 30, 1997, gives effect to the Offering
assuming the Underwriter's over-allotment option was not exercised.
 
    The pro forma consolidated financial statements are not necessarily
indicative of the consolidated financial position or results of future
operations of the combined entity or of the actual results that would have been
achieved had the PTC Merger and the Offering been consummated as of the dates
indicated.
 
NOTE 2
 
    Represents the acquisition adjustment which includes the elimination of
1,057,132 shares of common stock (including 30,731 options exercised) of PTC and
the issuance of 1,136,417 shares of the Company's common stock. The excess par
value of the issued shares over the retired shares has been adjusted to paid-in
capital.
 
NOTE 3
 
    Represents the temporary investment of the net proceeds of $17,460,000, debt
issue costs of $1,040,000, and $18,500,000 long-term debt incurred, all of which
are related to the issuance of the Preferred Securities.

ITEM 15.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under the Indiana Business Corporation Law, Indiana United Bancorp may
indemnify directors and officers against liabilities asserted against or
incurred by them while serving as such or while serving at its request as a
director, officer, partner, trustee, employee or agent of another foreign or
domestic corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise if (i) the individual's conduct was in good faith, (ii) the
individual believed:  (A) in the case of conduct in the individual's official
capacity, that the individual's conduct was in the corporation's best interests
and (B) in all other cases, that the individual's conduct was at least not
opposed to the corporation's best interests, and (iii) in the case of any
criminal proceeding, the individual either (A) had reasonable cause to believe
the individual's conduct was lawful or (B) had no reasonable cause to believe
the individual's conduct was unlawful.  Because its articles of incorporation do
not provide otherwise, Indiana United Bancorp is required under the Indiana
Business Corporation Law to indemnify a director or officer who was wholly
successful, on the merits or otherwise, in the defense of any proceeding in
which the director or officer was a party because the director or officer was
serving the corporation in such capacity against reasonable expenses incurred in
connection with the proceeding.

     The articles of incorporation of Indiana United Bancorp require the
indemnification of its directors and officers to the greatest extent permitted
by the Indiana Business Corporation Law.

     The Indiana Business Corporation Law also permits Indiana United Bancorp to
purchase and maintain on behalf of its directors and officers insurance against
liabilities asserted against or incurred by an individual in such capacity,
whether or not Indiana United Bancorp otherwise has the power to indemnify the
individual against the same liability under the Indiana Business Corporation
Law.  Under a directors' and officers' liability insurance policy, directors and
officers of Indiana United Bancorp are insured against certain liabilities,
including certain liabilities under the Securities Act of 1933, as amended.

ITEM 17.  UNDERTAKINGS

     Each of the undersigned registrants hereby undertakes that:

     (1)  It will 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 Exchange Act of 1934; and, where interim financial
information required 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 that is
specifically incorporated by reference in the prospectus to provide such interim
financial information.

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

     (3)  For purposes of determining any liability under the Securities
Act of 1933, as amended, the information omitted from the form of prospectus
filed as part of this Registration Statement in reliance upon Rule

                                      II-3

<PAGE>

430A and contained in a form of prospectus filed by the registrants pursuant to
Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
part of this Registration Statement as of the time it was declared effective.

     (4)  For the purpose of determining any liability under the
Securities Act of 1933, as amended, each post-effective amendment that contains
a form of prospectus 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 initial bona fide offering thereof.

     (5)  It shall provide to the Underwriter at the closing specified in the 
underwriting agreement, certificates in such denominations and registered in 
such names as required by the underwriter to permit prompt delivery to each 
purchaser.


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-2 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Greensburg, State of Indiana, on the 19th day of
November, 1997.

                                                          _______________, 1997



STIFEL, NICOLAUS & COMPANY, INCORPORATED
500 North Broadway
St. Louis, Missouri 63102


Dear Ladies and Gentlemen:

         Indiana United Bancorp, an Indiana corporation (the "Company"), and
its financing subsidiary, IUB Capital Trust, a Delaware business trust (the
"Trust," and hereinafter together with the Company, the "Offerors"), propose
that the Trust issue and sell to Stifel, Nicolaus & Company, Incorporated
(sometimes referred to herein as the "Underwriter"), pursuant to the terms of
this Agreement, 1,850,000 of the Trust's _____ % Cumulative Trust Preferred
Securities, with a liquidation amount of $10.00 per preferred security (the
"Preferred Securities"), to be issued under the Trust Agreement (as hereinafter
defined), the terms of which are more fully described in the Prospectus (as
hereinafter defined).  The aforementioned 1,850,000 Preferred Securities to be
sold to the Underwriter are herein called the "Firm Preferred Securities." 
Solely for the purpose of covering over-allotments in the sale of the Firm
Preferred Securities, the Offerors further propose that the Trust issue and sell
to the Underwriter, at its option, up to an additional 277,500 Preferred
Securities (the "Option Preferred Securities") upon exercise of the 
over-allotment option granted in Section 1 hereof.  The Firm Preferred 
Securities and any Option Preferred Securities are herein collectively 
referred to as the "Designated Preferred Securities."

         The Offerors hereby confirm as follows their agreement with you in
connection with the proposed purchase of the Designated Preferred Securities.

    1.   SALE, PURCHASE AND DELIVERY OF DESIGNATED PREFERRED SECURITIES;
DESCRIPTION OF DESIGNATED PREFERRED SECURITIES.

         (a)  On the basis of the representations, warranties and agreements
herein contained, and subject to the terms and conditions herein set forth, the
Offerors hereby agree that the Trust shall issue and sell to the Underwriter and
the Underwriter agrees to purchase from the Trust, at a purchase price of $10.00
per share (the "Purchase Price"), the Firm Preferred Securities.  Because the
proceeds from the sale of the Firm Preferred Securities will be used to purchase
from the Company its Debentures (as hereinafter defined and as described in the
Prospectus), the Company shall pay to the Underwriter a commission of $______ 
per Firm Preferred Security purchased (the "Firm Preferred Securities
Commission").

<PAGE>

         In addition, on the basis of the representations, warranties and
agreements herein contained and subject to the terms and conditions herein set
forth, the Trust hereby grants to the Underwriter an option to purchase all or
any portion of the 277,500 Option Preferred Securities, and upon the exercise of
such option in accordance with this Section 1, the Offerors hereby agree that
the Trust shall issue and sell to the Underwriter all or any portion of the
Option Preferred Securities at the same Purchase Price per share paid for the
Firm Preferred Securities.  Because the proceeds from the sale of the Option
Preferred Securities will be used to purchase from the Company its Debentures,
the Company shall pay to the Underwriter a commission of $_____ per Option
Preferred Security for each Option Preferred Security purchased (the "Option
Preferred Securities Commission").  The option hereby granted (the "Option")
shall expire 30 days after the date upon which the Registration Statement (as
hereinafter defined) becomes effective and may be exercised only for the purpose
of covering over-allotments which may be made in connection with the offering
and distribution of the Firm Preferred Securities.  The Option may be exercised
in whole or in part at any time (but not more than once) by the Underwriter
giving notice (confirmed in writing) to the Trust setting forth the number of
Option Preferred Securities as to which the Underwriter is exercising the Option
and the time, date and place for payment and delivery of certificates for such
Option Preferred Securities.  Such time and date of payment and delivery for the
Option Preferred Securities (the "Option Closing Date") shall be determined by
the Underwriter, but shall not be earlier than two nor later than five business
days after the exercise of such Option, nor in any event prior to the Closing
Date (as hereinafter defined).  The Option Closing Date may be the same as the
Closing Date.  

         Payment of the Purchase Price and the Firm Preferred Securities
Commission and delivery of certificates for the Firm Preferred Securities shall
be made at the Underwriter's offices, located at 500 North Broadway, St. Louis,
Missouri 63102, or such other place as shall be agreed to by the Underwriter and
the Offerors, at 10:00 a.m., St. Louis time, on _____________, 1997, or at such
other time not more than five full business days thereafter as the Offerors and
the Underwriter shall determine (the "Closing Date").  If the Underwriter
exercises the Option to purchase any or all of the Option Preferred Securities,
payment of the Purchase Price and Option Preferred Securities Commission and
delivery of certificates for such Option Preferred Securities shall be made on
the Option Closing Date at the Underwriter's offices, or at such other place as
the Offerors and the Underwriter shall determine.  Such payments shall be made
to an account designated by the Trust by wire transfer or certified or bank
cashier's check, in same day funds, in the amount of the Purchase Price
therefor, against delivery by or on behalf of the Trust to the Underwriter of
certificates for the Designated Preferred Securities to be purchased by the
Underwriter.

         The Agreement contained herein with respect to the timing of the
Closing Date and Option Closing Date is intended to, and does, constitute an
express agreement, as described in Rule 15c6-[1(c)/1(a)] and (d) promulgated
under the 1934 Act (as defined herein), for a settlement date other than
[FOUR/THREE] business days after the date of the contract.

         Certificates for Designated Preferred Securities to be purchased by
the Underwriter shall be delivered by the Offerors in fully registered form in
such authorized denominations and registered in such names as the Underwriter
shall request in writing not later than 12:00 noon, St. Louis time, two business
days prior to the Closing Date and, if applicable, the Option Closing Date. 
Certificates for Designated Preferred Securities to be purchased by the
Underwriter shall be made available by the Offerors to the Underwriter for
inspection, checking and packaging at such office as the Underwriter may
designate in writing not later than 1:00 p.m., St. Louis time, on the last
business day prior to the Closing Date and, if applicable, on the last business
day prior to the Option Closing Date.

         Time shall be of the essence, and delivery of the certificates for the
Designated Preferred Securities at the time and place specified pursuant to this
Agreement is a further condition of the Underwriter's obligations hereunder.


                                       2

         (b)  The Offerors propose that the Trust issue the Designated
Preferred Securities pursuant to an Amended and Restated Trust Agreement among
State Street Bank and Trust Company, as Property Trustee, Wilmington Trust
Company, as Delaware Trustee, the Administrative Trustees named therein,
(collectively, the "Trustees"), and the Company, in substantially the form
heretofore delivered to the Underwriter, said Agreement being hereinafter
referred to as the "Trust Agreement."  In connection with the issuance of the
Designated Preferred Securities, the Company proposes (i) to issue its
Subordinated Debentures ( the "Debentures") pursuant to an Indenture, to be
dated as of ______________, 1997, between the Company and State Street Bank 
and Trust Company, as Trustee (the "Indenture") and (ii) to guarantee certain
payments on the Designated Preferred Securities pursuant to a Preferred
Securities Guarantee Agreement between the Company and State Street Bank and
Trust Company, as guarantee trustee (the "Guarantee"), to the extent described
therein.

    2.   REPRESENTATIONS AND WARRANTIES.

agree with, the Underwriter that:

    thereunder (the "1934 Act Regulations") at the time they were filed with
    the Commission, complied as to form in all material respects with the
    requirements of the 1934 Act and the 1934 Act Regulations and did not
    contain an untrue statement of a material fact or omit to state a material

    430A") or permitted by Rule 424(b) of the 1933 Act Regulations ("Rule
    424(b)") and as have been provided to and not objected to by the
    Underwriter prior to (or as are agreed to by the Underwriter subsequent to) 
    the execution of this Agreement, or (B) if such registration statement, as 
    it may have been amended, has not been declared by the  Commission to be 
    effective under the 1933 Act, an amendment to such registration statement,

    statement to become effective, a copy of which amendment has been furnished

    subsequent to) the execution of this Agreement.  As used in this 
    Agreement, the term "Registration Statement" means such registration 
    statement, as amended at the time when it was or is declared effective 
    under the 1933 Act, including (1) all financial schedules and exhibits 
    thereto, (2) all documents (or portions thereof) incorporated by

    Statement and each prospectus filed pursuant to Rule 424(a) under the 
    1933 Act); and the term "Prospectus" means the prospectus first filed 
    with the Commission pursuant to Rule 424(b)(1) or (4) or, if no 
    prospectus is required to be filed pursuant to Rule 424(b)(1) or (4), the 
    prospectus included in the Registration Statement, in each case including 
    the financial schedules and all documents (or portions thereof) 
    incorporated by reference therein under the 1934 Act.  The date on which 
    the Registration Statement becomes effective is hereinafter referred to 
    as the "Effective Date."

              (iii) The documents incorporated by reference in the
    Preliminary Prospectus or Prospectus or from which information is so
    incorporated by reference, when they became effective or were filed with
    the Commission, as the case may be, complied in all material respects with
    the requirements of the 1934 Act and the 1934 Act Regulations, and when
    read together and with the other information in the Preliminary Prospectus
    or Prospectus, as the case may be, at the time the Registration Statement
    became or becomes effective and at the Closing Date and any Option Closing
    Date, did not or will not, as the case may be, contain an untrue statement
    of a material fact or omit to state a material fact required to be stated

    (or, if the Prospectus is not in existence, the most recent Preliminary
    Prospectus) has been issued by the Commission, nor has the Commission, to
    the knowledge of the Offerors, threatened to issue such an order or
    instituted proceedings for that purpose.  Each Preliminary Prospectus, at
    the time of filing thereof, (A) complied in all material respects with the
    requirements of the 1933 Act and the 1933 Act Regulations and (B) did not
    contain an untrue statement of a material fact or omit to state any
    material fact required to be stated therein or necessary to make the

    of the 1933 Act, the 1933 Act Regulations and the Trust Indenture Act (and
    the rules and regulations thereunder) and (B) did not and will not contain
    an untrue statement of a material fact or omit to state a material fact

    is required to be delivered in connection with offers and sales of
    Designated Preferred Securities, including, without limitation, the Closing
    Date and, if applicable, the Option Closing Date, the Prospectus, as
    amended or supplemented, (A) complied and will comply in all material
    respects with the requirements of the 1933 Act and the 1933 Act Regulations
    and the Trust Indenture Act (and the rules and regulations thereunder) and
    (B) did not contain and will not contain an untrue statement of a material
    fact or omit to state any material fact required to be stated therein or
    necessary to make the statements therein, in light of the circumstances
    under which they were made, not misleading.

    Date will not be classified as an association taxable as a corporation for
    United States federal income tax purposes; and the Trust is, and as of the

    accounts of the Banks are insured by the Bank Insurance Fund administered
    by the Federal Deposit Insurance Corporation (the "FDIC") up to the maximum
    amount provided by law; and no proceedings for the modification,
    termination or revocation of any such insurance are pending or threatened.

              (viii) The Company and each of the Subsidiaries is duly qualified
    to transact business as a foreign corporation and is in good standing in

    of each Offeror have been duly authorized and validly issued and are fully
    paid and nonassessable, and no such shares were issued in violation of the
    preemptive or similar rights of any security holder of an Offeror; no
    person has any preemptive or similar right to purchase any shares of
    capital stock or equity securities of the Offerors.  Except as disclosed in

    or other instrument to which an Offeror is a party or by which an Offeror
    is bound.

    with and upon the terms and conditions set forth in this Agreement, the
    Trust Agreement, the Registration Statement and the Prospectus (or, if the

    All corporate and trust action required to be taken by the Offerors for the
    authorization, issuance, sale and delivery of the Designated Preferred
    Securities in accordance with such terms and conditions has been validly

    Securities, immediately prior to delivery, will be subject to any security
    interest, lien, mortgage, pledge, encumbrance, restriction upon voting or

    Offering, other than a Preliminary Prospectus, the Prospectus, the
    Registration Statement and the other materials permitted by the 1933 Act
    and the 1933 Act Regulations and reviewed by the Underwriter.

    3.  OFFERING BY THE UNDERWRITER.  After the Registration Statement becomes
effective or, if the Registration Statement is already effective, after this
Agreement becomes effective, the Underwriter proposes to offer the Firm
Preferred Securities for sale to the public upon the terms and conditions set
forth in the Prospectus.  The Underwriter may from time to time thereafter
reduce the public offering price and change the other selling terms, provided
the proceeds to the Trust shall not be reduced as a result of such reduction or
change.  Because the National Association of Securities Dealers, Inc. ("NASD")
is expected to view the Preferred Securities as interests in a direct
participation program, the offering of the Preferred Securities is being made in
compliance with the applicable provisions of Rule 2810 of the NASD's Conduct
Rules.

         The Underwriter may reserve and sell such of the Designated Preferred
Securities purchased by the Underwriter as the Underwriter may elect to dealers
chosen by it (the "Selected Dealers") at the public offering price set forth in
the Prospectus less the applicable Selected Dealers' concessions set forth
therein, for re-offering by Selected Dealers to the public at the public
offering price.  The Underwriter may allow, and Selected Dealers may re-allow, a
concession set forth in the Prospectus to certain other brokers and dealers.

    4.  CERTAIN COVENANTS OF THE OFFERORS.  The Offerors jointly and 
severally covenant with the Underwriter as follows:

         (a)  The Offerors shall use their best efforts to cause the
Registration Statement and any amendments thereto, if not effective at the time
of execution of this Agreement, to become effective as promptly as possible.  If
the Registration Statement has become or becomes effective pursuant to Rule 430A
and information has been omitted therefrom in reliance on Rule 430A, then, the
Offerors will prepare and file in accordance with Rule 430A and Rule 424(b)
copies of the Prospectus or, if required by Rule 430A, a post-effective
amendment to the Registration Statement (including the Prospectus) containing
all information so omitted and will provide evidence satisfactory to the
Underwriter of such timely filing.

         (b)  The Offerors shall notify the Underwriter immediately, and
confirm such notice in writing:

              (i)  when the Registration Statement, or any post-effective
    amendment to the Registration Statement, has become effective, or when the
    Prospectus or any supplement to the Prospectus or any amended Prospectus
    has been filed;

              (ii) of the receipt of any comments or requests from the
    Commission relating in any way to the Registration Statement, any
    Preliminary Prospectus, the Prospectus, or any amendments or supplements to
    any of the aforementioned;

              (iii)  of any request of the Commission to amend or supplement
    the Registration Statement, any Preliminary Prospectus or the Prospectus or
    for additional information; and


                                      12

<PAGE>

              (iv)  of the issuance by the Commission or any state or other
    regulatory body of any stop order or other order suspending the
    effectiveness of the Registration Statement, preventing or suspending the
    use of any Preliminary Prospectus or the Prospectus, or suspending the
    qualification of any of the Designated Preferred Securities for offering or
    sale in any jurisdiction or the institution or threat of institution of any
    proceedings for any of such purposes.  The Offerors shall use their best
    efforts to prevent the issuance of any such stop order or of any other such
    order and, if any such order is issued, to cause such order to be withdrawn
    or lifted as soon as possible.

         (c)  The Offerors shall furnish to the Underwriter, from time to time
without charge, as soon as available, as many copies as the Underwriter may
reasonably request of (i) the registration statement as originally filed and of
all amendments thereto, in executed form, including exhibits, whether filed
before or after the Registration Statement becomes effective, (ii) all exhibits
and documents incorporated therein or filed therewith, (iii) all consents and
certificates of experts in executed form, (iv) each Preliminary Prospectus and
all amendments and supplements thereto, and (v) the Prospectus, and all
amendments and supplements thereto.

         (d)  During the time when a prospectus is required to be delivered
under the 1933 Act, the Offerors shall comply to the best of their ability with
the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act
Regulations so as to permit the completion of the distribution of the Designated
Preferred Securities as contemplated herein and in the Trust Agreement and the
Prospectus.  The Offerors shall not file any amendment to the registration
statement as originally filed or to the Registration Statement and shall not
file any amendment thereto or make any amendment or supplement to any
Preliminary Prospectus or to the Prospectus of which the Underwriter shall not
previously have been advised in writing and provided a copy within a reasonable
time prior to the proposed filings thereof or to which the Underwriter or its
counsel shall object.  If it is necessary, in the Company's reasonable opinion
or in the reasonable opinion of the Company's counsel, to amend or supplement
the Registration Statement or the Prospectus in connection with the distribution
of the Designated Preferred Securities, the Offerors shall forthwith amend or
supplement the Registration Statement or the Prospectus, as the case may be, by
preparing and filing with the Commission (provided the Underwriter or its
counsel does not reasonably object), and furnishing to the Underwriter, such
number of copies as the Underwriter may reasonably request of an amendment or
amendments of, or a supplement or supplements to, the Registration Statement or
the Prospectus, as the case may be (in form and substance reasonably
satisfactory to the Underwriter and its counsel).  If any event shall occur as a
result of which it is necessary to amend or supplement the Prospectus to correct
an untrue statement of a material fact or to include a material fact necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading, or if for any reason it is necessary at any time to
amend or supplement the Prospectus to comply with the 1933 Act and the 1933 Act
Regulations, the Offerors shall, subject to the second sentence of this
subsection (d), forthwith amend or supplement the Prospectus by preparing and
filing with the Commission, and furnishing to the Underwriter, such number of
copies as the Underwriter may reasonably request of an amendment or amendments
of, or a supplement or supplements to, the Prospectus (in form and substance
satisfactory to the Underwriter and its counsel) so that, as so amended or
supplemented, the Prospectus shall not contain an untrue statement of a material
fact or omit to state a material fact necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.  

         (e)  The Offerors shall cooperate with the Underwriter and its counsel
in order to qualify the Designated Preferred Securities for offering and sale
under the securities or blue sky laws of such jurisdictions as the Underwriter
may reasonably request and shall continue such qualifications in effect so long
as may be advisable for distribution of the Designated Preferred Securities;
provided, however, that the Offerors shall not be required to qualify to do
business as a foreign corporation or file a general consent to service of
process in any jurisdiction in connection 


                                      13

<PAGE>

with the foregoing.  The Offerors shall file such statements and reports as 
may be required by the laws of each jurisdiction in which the Designated 
Preferred Securities have been qualified as above.  The Offerors will notify 
the Underwriter immediately of, and confirm in writing, the suspension of 
qualification of the Designated Preferred Securities or threat thereof in any 
jurisdiction.

         (f)  The Offerors shall make generally available to their security
holders in the manner contemplated by Rule 158 of the 1933 Act Regulations and
furnish to the Underwriter as soon as practicable, but in any event not later
than 16 months after the Effective Date, a consolidated earnings statement of
the Offerors conforming with the requirements of Section 11(a) of the 1933 Act
and Rule 158.

         (g)  The Offerors shall use the proceeds from the sale of the
Designated Preferred Securities to be sold by the Trust hereunder in the manner
specified in the Prospectus under the caption "Use of Proceeds."

         (h)  For five years from the Effective Date, the Offerors shall
furnish to the Underwriter copies of all reports and communications (financial
or otherwise) furnished by the Offerors to the holders of the Designated
Preferred Securities as a class, copies of all reports and financial statements
filed with or furnished to the Commission (other than portions for which
confidential treatment has been obtained from the Commission) or with any
national securities exchange or the Nasdaq National Market and such other
documents, reports and information concerning the business and financial
conditions of the Offerors as the Underwriter may reasonably request, other than
such documents, reports and information for which the Offerors have the legal
obligation not to reveal to the Underwriter.

         (i)  For a period of 30 days from the Effective Date, the Offerors
shall not, directly or indirectly, offer for sale, sell or agree to sell or
otherwise dispose of any Designated Preferred Securities other than pursuant to
this Agreement, any other beneficial interests in the assets of the Trust or any
securities of the Trust or the Company that are substantially similar to the
Designated Preferred Securities or the Debentures, including any guarantee of
such beneficial interests or substantially similar securities, or securities
convertible into or exchangeable for or that represent the right to receive any
such beneficial interest or substantially similar securities without the
Underwriter's prior written consent.

         (j)  The Offerors shall use their best efforts to cause the Designated
Preferred Securities to become quoted on the Nasdaq National Market, or in lieu
thereof a national securities exchange, and to remain so quoted for at least
five years from the Effective Date or for such shorter period as may be
specified in a written consent of the Underwriter, provided this shall not
prevent the Company from redeeming the Designated Preferred Securities pursuant
to the terms of the Trust Agreement.  If the Designated Preferred Securities are
exchanged for Debentures, the Company will use its best efforts to have the
Debentures promptly listed on the Nasdaq National Market or other organization
on which the Designated Preferred Securities are then listed, and to have the
Debentures promptly registered under the 1934 Act.

         (k)  Subsequent to the date of this Agreement and through the date
which is the later of (i) the day following the date on which the Underwriter's
option to purchase the Option Preferred Securities shall expire or (ii) the day
following the Option Closing Date with respect to any Option Preferred
Securities that the Underwriter shall elect to purchase, except as described in
or contemplated by the Prospectus, neither the Offerors nor any of the
Subsidiaries shall take any action (or refrain from taking any action) which
will result in the Offerors or the Subsidiaries incurring any material liability
or obligation, direct or contingent, or enter into any material transaction,
except in the ordinary course of business, and there will not be any material
change in the financial position, capital stock, or any material increase in
long-term debt, obligations under capital leases or short-term borrowings of the
Offerors and the Subsidiaries on a consolidated basis.


                                      14

<PAGE>

         (l)  The Offerors shall not, for a period of 180 days after the date
hereof, without the prior written consent of the Underwriter, purchase, redeem
or call for redemption, or prepay or give notice of prepayment (or announce any
redemption or call for redemption, or any repayment or notice of repayment) of
any of the Offeror's securities.

         (m)  The Offerors shall not take, directly or indirectly, any action
designed to result in or which has constituted or which might reasonably be
expected to (i) cause or result in stabilization or manipulation of the price of
any security of the Offerors to facilitate the sale or resale of the Designated
Preferred Securities or (ii) otherwise violate the Commission's Regulation M.

         (n)  Prior to the Closing Date (and, if applicable, the Option Closing
Date), the Offerors will not issue any press release or other communication
directly or indirectly or hold any press conference with respect to the
Offerors, the Subsidiaries or the offering of the Designated Preferred
Securities (the "Offering") without the Underwriter's prior written consent.

    5.  PAYMENT OF EXPENSES.  Whether or not this Agreement is terminated or
the sale of the Designated Preferred Securities to the Underwriter is
consummated, the Company covenants and agrees that it will pay or cause to be

Preferred Securities to the Underwriter;

         (j)  all other costs and expenses incident to the performance of the

otherwise specifically provided for in this Section 5.

         If the sale of Designated Preferred Securities contemplated by this
Agreement is not completed for any reason whatsoever, whether or not such
termination is allowable hereunder, the Company will pay the Underwriter its
accountable out-of-pocket expenses in connection herewith or in contemplation of
the performance of the Underwriter's obligations hereunder, including, without
limitation, travel expenses, reasonable fees, expenses and disbursements of
counsel or other out-of-pocket expenses incurred by the Underwriter in
connection with any discussion of the Offering or the contents of the
Registration Statement, any investigation of the Offerors and the Subsidiaries,
or any preparation for the marketing, purchase, sale or delivery of the
Designated Preferred Securities, in each case following presentation of
reasonably detailed invoices therefor.

         If the sale of Designated Preferred Securities contemplated by this
Agreement is completed, the Company shall not be responsible for payment of fees

Underwriter.

    6.  CONDITIONS OF THE UNDERWRITER'S OBLIGATIONS.  The obligations of the
Underwriter to purchase and pay for the Firm Preferred Securities and, following
exercise of the option granted by the Offerors in Section 1 of this Agreement,
the Option Preferred Securities, are subject, in the Underwriter's sole
discretion, to the accuracy of and compliance with the representations and
warranties and agreements of the Offerors herein as of the date hereof and as of
the Closing Date (or in the case of the Option Preferred Securities, if any, as
of the Option Closing Date), to the accuracy of the written statements of the
Offerors made pursuant to the provisions hereof, to the performance by the
Offerors of their covenants and obligations hereunder and to the following
additional conditions:

         (a)  If the Registration Statement or any amendment thereto filed
prior to the Closing Date has not been declared effective prior to the time of
execution hereof, the Registration Statement shall become effective not later
than 10:00 a.m., St. Louis time, on the first business day following the time of
execution of this Agreement, or at such later time and date as the Underwriter
may agree to in writing.  If required, the Prospectus and any amendment or
supplement thereto shall have been timely filed in accordance with Rule 424(b)
and Rule 430A under the 1933 Act and Section 4(a) hereof.  No stop order
suspending the effectiveness of the Registration Statement or any amendment or
supplement thereto shall have been issued under the 1933 Act or any applicable
state securities laws and no proceedings for that purpose shall have been
instituted or shall be pending, or, to the knowledge of the Offerors or the
Underwriter, shall be contemplated by the Commission or any state authority. 
Any request on the part of the Commission or any state authority for additional
information (to be included in the Registration Statement or Prospectus or
otherwise) shall have been disclosed to the Underwriter and complied with to the
satisfaction of the Underwriter and its counsel.

         (b)  The Underwriter shall not have advised the Company at or before
the Closing Date (and, if applicable, the Option Closing Date) that the
Registration Statement or any post-effective amendment thereto, or the
Prospectus or any amendment or supplement thereto, contains an untrue statement
of a fact which, in the Underwriter's opinion, is material or omits to state a
fact 


                                      16

<PAGE>


which, in the Underwriter's opinion, is material and is required to be stated 
therein or is necessary to make statements therein (in the case of the 
Prospectus or any amendment or supplement thereto, in light of the 
circumstances under which they were made) not misleading.

         (c)  All corporate proceedings and other legal matters incident to the
authorization, form and validity of this Agreement, the Trust Agreement, and the
Designated Preferred Securities, and the authorization and form of the
Registration Statement and Prospectus, other than financial statements and other
financial data, and all other legal matters relating to this Agreement and the
transactions contemplated hereby or by the Trust Agreement shall be satisfactory
in all material respects to counsel to the Underwriter, and the Offerors and the
Subsidiaries shall have furnished to such counsel all documents and information
relating thereto that they may reasonably request to enable them to pass upon
such matters.

         (d)  [GREENEBAUM, DOLL & MCDONALD] [DAVID W. HARPER, ESQ.], counsel to
the Offerors, shall have furnished to the Underwriter its signed opinion, dated
the Closing Date or the Option Closing Date, as the case may be, in form and
substance satisfactory to counsel to the Underwriter, to the effect that:

              (i)  The Company has been duly incorporated and is validly
    existing and in good standing under the laws of the State of Indiana, and
    is duly registered as a bank holding company under the BHC Act.  Each of
    the Subsidiaries is duly incorporated, validly existing and in good
    standing under the laws of its jurisdiction of incorporation.  Each of the
    Company and the Subsidiaries has full corporate power and authority to own
    or lease its properties and to conduct its business as such business is
    described in the Prospectus and is currently conducted in all material
    respects.  All outstanding shares of capital stock of the Subsidiaries have
    been duly authorized and validly issued and are fully paid and
    nonassessable, except to the extent such shares may be deemed assessable
    under 12 U.S.C. Section 1831, and to the best of such counsel's knowledge,
    there are no outstanding rights, options or warrants to purchase any such
    shares or securities convertible into or exchangeable for any such shares.

              (ii) The capital stock, Debentures and Guarantee of the Company
    and the equity securities of the Trust conform to the description thereof
    contained in the Prospectus in all material respects.  The capital stock of
    the Company authorized and issued as of                , 1997, is as set
    forth under the caption "Capitalization" in the Prospectus and has been
    duly authorized, validly issued, and is fully paid and nonassessable.  To
    the best of such counsel's knowledge, there are no outstanding rights,
    options or warrants to purchase, no other outstanding securities
    convertible into or exchangeable for, and no commitments, plans or
    arrangements to issue, any shares of capital stock of the Company or equity
    securities of the Trust, except as described in the Prospectus.

              (iii)  The issuance, sale and delivery of the Designated
    Preferred Securities and Debentures in accordance with the terms and
    conditions of this Agreement and the Indenture have been duly authorized by
    all necessary actions of the Offerors.  All of the Designated Preferred
    Securities have been duly and validly authorized and, when delivered in
    accordance with this Agreement, will be duly and validly issued, fully paid
    and nonassessable, and will conform to the description thereof in the
    Registration Statement, the Prospectus and the Trust Agreement.  The
    Designated Preferred Securities have been approved for quotation on the
    Nasdaq National Market subject to official notice of issuance.  There are
    no preemptive or other rights to subscribe for or to purchase, and no
    restrictions upon the voting or transfer of, any shares of capital stock or
    equity securities of the Offerors or the Subsidiaries pursuant to the
    corporate charter, by-laws or other governing documents (including, without
    limitation, the Trust Agreement) of the Offerors or the Subsidiaries, or,
    to the best of such counsel's knowledge, any agreement or other instrument
    to which either 


                                      17

<PAGE>


    Offeror or any of the Subsidiaries is a party or by which either Offeror or 
    any of the Subsidiaries may be bound.

              (iv) The Offerors have all requisite corporate and trust power to
    enter into and perform their obligations under this Agreement, and this
    Agreement has been duly and validly authorized, executed and delivered by
    the Offerors and constitutes the legal, valid and binding obligations of
    the Offerors enforceable in accordance with its terms, except as the
    enforcement hereof or thereof may be limited by general principles of
    equity and by bankruptcy or other laws relating to or affecting creditors'
    rights generally, and except as the indemnification and contribution
    provisions hereof may be limited under applicable laws and certain remedies
    may not be available in the case of a non-material breach.

              (v)  Each of the Indenture, the Trust Agreement and the Guarantee
    has been duly qualified under the Trust Indenture Act, has been duly
    authorized, executed and delivered by the Company, and is a valid and
    legally binding obligation of the Company enforceable in accordance with
    its terms, subject to the effect of bankruptcy, insolvency, reorganization,
    receivership, moratorium and other laws affecting the rights and remedies
    of creditors generally and of general principles of equity.

              (vi) The Debentures have been duly authorized, executed,
    authenticated and delivered by the Company, are entitled to the benefits of
    the Indenture and are legal, valid and binding obligations of the Company
    enforceable against the Company in accordance with their terms, subject to
    the effect of bankruptcy, insolvency, reorganization, receivership,
    moratorium and other laws affecting the rights and remedies of creditors
    generally and of general principles of equity.

              (vii)  The Expense Agreement has been duly authorized,
    executed and delivered by the Company, and is a valid and legally binding
    obligation of the Company enforceable in accordance with its terms, subject
    to the effect of bankruptcy, insolvency, reorganization, receivership,
    moratorium and other laws affecting the rights and remedies of creditors
    generally and of general principles of equity.

              (viii)  To the best of such counsel's knowledge, neither of the
    Offerors nor any of the Subsidiaries is in breach or violation of, or
    default under, with or without notice or lapse of time or both, its
    corporate charter, by-laws or governing document (including, without
    limitation, the Trust Agreement).  The execution, delivery and performance
    of this Agreement and the consummation of the transactions contemplated by
    this Agreement and the Trust Agreement do not and will not conflict with,
    result in the creation or imposition of any material lien, claim, charge,
    encumbrance or restriction upon any property or assets of the Offerors or
    the Subsidiaries or the Designated Preferred Securities pursuant to, or
    constitute a material breach or violation of, or constitute a material
    default under, with or without notice or lapse of time or both, any of the
    terms, provisions or conditions of the charter, by-laws or governing
    document (including, without limitation, the Trust Agreement) of the
    Offerors or the Subsidiaries, or to the best of such counsel's knowledge,
    the Guarantee, the Indenture or any material contract, indenture, mortgage,
    deed of trust, loan or credit agreement, note, lease, franchise, license or
    any other agreement or instrument to which either Offeror or the
    Subsidiaries is a party or by which any of them or any of their respective
    properties may be bound or any order, decree, judgment, franchise, license,
    Permit, rule or regulation of any court, arbitrator, government, or
    governmental agency or instrumentality, domestic or foreign, known to such
    counsel having jurisdiction over the Offerors or the Subsidiaries or any of
    their respective properties which, in each case, is material to the
    Offerors and the Subsidiaries on a consolidated basis.  No authorization,
    approval, consent or order of, or filing, registration or qualification
    with, any person 


                                      18

    (including, without limitation, any court, governmental body or authority) 
    is required under Indiana law in connection with the transactions 
    contemplated by this Agreement in connection with the purchase and 
    distribution of the Designated Preferred Securities by the Underwriter.

              (ix) To the best of such counsel's knowledge, holders of
    securities of the Offerors either do not have any right that, if exercised,
    would require the Offerors to cause such securities to be included in the
    Registration Statement or have waived such right.  To the best of such
    counsel's knowledge, neither the Offerors nor any of the Subsidiaries is a
    party to any agreement or other instrument which grants rights for or
    relating to the registration of any securities of the Offerors.

              (x)  To the best of such counsel's knowledge, (i) no action, suit
    or proceeding at law or in equity is pending or threatened in writing to
    which the Offerors or the Subsidiaries is or may be a party, and (ii) no
    action, suit or proceeding is pending or threatened in writing against or
    affecting the Offerors or the Subsidiaries or any of their properties,
    before or by any court or governmental official, commission, board or other
    administrative agency, authority or body, or any arbitrator.

              (xi) No authorization, approval, consent or order of or filing,
    registration or qualification with, any person (including, without
    limitation, any court, governmental body or authority) is required in
    connection with the transactions contemplated by this Agreement, the Trust
    Agreement, the Registration Statement and the Prospectus, except such as
    have been obtained under the 1933 Act, the Trust Indenture Act, and except
    such as may be required under state securities laws or Interpretations or
    Rules of the NASD in connection with the purchase and distribution of the
    Designated Preferred Securities by the Underwriter.

              (xii)  The Registration Statement and the Prospectus and any
    amendments or supplements thereto and any documents incorporated therein by
    reference (other than the financial statements or other financial data
    included therein or omitted therefrom) comply as to form in all material
    respects with the requirements of the 1933 Act and the 1933 Act Regulations
    as of their respective dates of effectiveness.

              (xiii)  To the best of such counsel's knowledge, there are no
    contracts, agreements, leases or other documents of a character required to
    be disclosed in the Registration Statement or Prospectus or to be filed as
    exhibits to the Registration Statement that are not so disclosed or filed.

              (xiv)  The statements under the captions "Description of the

    "Description of the Guarantee," "Relationship Among the Preferred
    Securities, the Subordinated Debentures and the Guarantee," "Certain
    Federal Income Tax Consequences," "ERISA Considerations," "General -
    Supervision and Regulation" and "Legislation" in the Prospectus or
    incorporated therein by reference, insofar as such statements constitute a
    summary of legal and regulatory matters, documents, instruments or
    proceedings referred to therein, are accurate descriptions of the matters
    summarized therein in all material respects and fairly present the
    information called for with respect to such legal matters, documents and
    instruments, other than financial and statistical data , as to which said
    counsel shall not be required to express any opinion or belief.

              (xv) Such counsel has been advised by the staff of the Commission
    that the Registration Statement has become effective under the 1933 Act;
    any required filing of the Prospectus pursuant to Rule 424(b) has been made
    within the time period required by 


                                      19

<PAGE>

    Rule 424(b); to the best of such counsel's knowledge, no stop order 
    suspending the effectiveness of the Registration Statement has been issued 
    and no proceedings for a stop order are pending or threatened by the 
    Commission.

              (xvi)  Except as set forth in the Prospectus, to the best of
    such counsel's knowledge, there are no contractual encumbrances or
    restrictions, or material legal restrictions required to be described
    therein on the ability of the Subsidiaries (A) to pay dividends or make any
    other distributions on its capital stock or to pay indebtedness owed to the
    Offerors, (B) to make any loans or advances to, or investments in, the
    Offerors or (C) to transfer any of its property or assets to the Offerors.

              (xvii)  To the best of such counsel's knowledge, (A) the
    business and operations of the Offerors and the Subsidiaries comply in all
    material respects with all statutes, ordinances, laws, rules and
    regulations applicable thereto and which are material to the Offerors and
    the Subsidiaries on a consolidated basis, except those instances where non-
    compliance would not materially impair the ability of the Offerors and the
    Subsidiaries to conduct their businesses; and (B) the Offerors and the
    Subsidiaries possess and are operating in all material respects in
    compliance with the terms, provisions and conditions of all Permits that
    are required to conduct their businesses as described in the Prospectus and
    that are material to the Offerors and the Subsidiaries on a consolidated
    basis, except in those instances where the loss thereof or non-compliance
    therewith would not have a material adverse effect on the condition
    (financial or otherwise), earnings, affairs, business, prospects or results
    of operations of the Offerors and the Subsidiaries on a consolidated basis;
    and to the best of such counsel's knowledge, all such Permits are valid and
    in full force and effect, and, to the best of such counsel's knowledge, no
    action, suit or proceeding is pending or threatened which may lead to the
    revocation, termination, suspension or non-renewal of any such Permit,
    except in those instances where the loss thereof or non-compliance
    therewith would not materially impair the ability of the Offerors or the
    Subsidiaries to conduct their businesses.

         In giving the above opinion, such counsel may state that, insofar as
such opinion involves factual matters, they have relied upon certificates of
officers of the Offerors including, without limitation, certificates as to the
identity of any and all material contracts, indentures, mortgages, deeds of
trust, loans or credit agreements, notes, leases, franchises, licenses or other
agreements or instruments, and all material permits, easements, consents,
licenses, franchises and government regulatory authorizations, for purposes of
paragraphs (viii), (xiii) and (xvii) hereof and upon certificates of public
officials.  In giving such opinion, such counsel may rely upon the opinion of
Richards, Layton and Finger described herein as to matters of Delaware Law.

         Such counsel shall also confirm that, in connection with the
preparation of the Registration Statement and Prospectus, such counsel has
participated in conferences with officers and representatives of the Offerors
and with their independent public accountants and with the Underwriter and its
counsel, at which conferences such counsel made inquiries of such officers,
representatives and accountants and discussed in detail the contents of the
Registration Statement and Prospectus and the documents incorporated therein by
reference (without taking further action to verify independently the statements
made in the Registration Statement and the Prospectus, and without assuming
responsibility for the accuracy or completeness of such statements, except to
the extent expressly provided above) and such counsel has no reason to believe
(A) that the Registration Statement or any amendment thereto (except for the
financial statements and related schedules and statistical data included therein
or omitted therefrom), at the time the Registration Statement or any such
amendment became effective, contained any untrue statement of a material fact or
omitted to state any 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 or (B) that the Prospectus or any amendment or
supplement thereto or the documents incorporated therein by 


                                      20

<PAGE>


reference (except for the financial statements and related schedules and 
statistical data included therein or omitted therefrom), at the time the 
Registration Statement became effective (or, if the term "Prospectus" refers 
to the prospectus first filed pursuant to Rule 424(b) of the 1933 Act 
Regulations, at the time the Prospectus was issued), at the time any such 
amended or supplemented Prospectus was issued, at the Closing Date and, if 
applicable, the Option Closing Date, contained or contains any untrue 
statement of a material fact or omitted or omits to state any material fact 
required to be stated therein or necessary to make the statements therein not 
misleading, or (C) that there is any amendment to the Registration Statement 
required to be filed that has not already been filed.

         (e)  Richards, Layton and Finger, special Delaware counsel to the
Offerors, shall have furnished to the Underwriter its signed opinion, dated as
of Closing Date or the Option Closing Date, as the case may be, in form and
substance satisfactory to such counsel, to the effect that:

              (i)  The Trust has been duly created and is validly existing in
    good standing as a business trust under the Delaware Business Trust Act
    and, under the Trust Agreement and the Delaware Business Trust Act, has the
    trust power and authority to conduct its business as described in the
    Prospectus.

              (ii) The Trust Agreement is a legal, valid and binding agreement
    of the Trust and the Trustees, and is enforceable against the Company, as
    depositor, and the Trustees, in accordance with its terms.

              (iii)  Under the Trust Agreement and the Delaware Business
    Trust Act, the execution and delivery of the Underwriting Agreement by the
    Trust, and the performance by the Trust of its obligations thereunder, have
    been authorized by all requisite trust action on the part of the Trust.

              (iv) The Designated Preferred Securities have been duly
    authorized by the Trust Agreement, and when issued and sold in accordance
    with the Trust Agreement, the Designated Preferred Securities will be,
    subject to the qualifications set forth in paragraph (v) below, fully paid
    and nonassessable beneficial interest in the assets of the Trust and
    entitled to the benefits of the Trust Agreement.  The form of certificates
    to evidence the Designated Preferred Securities has been approved by the
    Trust and is in due and proper form and complies with all applicable
    requirements of the Delaware Business Trust Act.  

              (v)  Holders of Designated Preferred Securities, as beneficial
    owners of the Trust, will be entitled to the same limitation on personal
    liability extended to shareholders of private, for-profit corporations
    organized under the General Corporation Law of the State of Delaware.  Such
    opinion may note that the holders of Designated Preferred Securities may be
    obligated to make payments as set forth in the Trust Agreement.

              (vi) Under the Delaware Business Trust Act and the Trust
    Agreement, the issuance of the Designated Preferred Securities is not
    subject to preemptive rights. 

              (vii)  The issuance and sale by the Trust of the Designated
    Preferred Securities and the Common Securities, the execution, delivery and
    performance by the Trust of this Agreement, and the consummation of the
    transactions contemplated by this Agreement, do not violate (a) the Trust
    Agreement, or (b) any applicable Delaware law, rule or regulation.

         Such opinion may state that it is limited to the laws of the State of
Delaware and that the opinion expressed in paragraph (ii) above is subject to
the effect upon the Trust Agreement of (i) bankruptcy, insolvency, moratorium,
receivership, reorganization, liquidation, fraudulent 


                                      21

conveyance and other similar laws relating to or affecting the rights and 
remedies of creditors generally, (ii) principles of equity, including 
applicable law relating to fiduciary duties (regardless of whether considered 
and applied in a proceeding in equity or at law), and (iii) the effect of 
applicable public policy on the enforceability of provisions relating to 
indemnification or contribution.
         
         (f)  Bryan Cave LLP, counsel to the Underwriter, shall have 
furnished to the Underwriter its signed opinion, dated the Closing Date or 
the Option Closing Date, as the case may be, with respect to the sufficiency 
of all corporate procedures and other legal matters relating to this 
Agreement, the validity of the Designated Preferred Securities, the 
Registration Statement, the Prospectus and such other related matters as the 
Underwriter may reasonably request and there shall have been furnished to 
such counsel such documents and other information as it may request to enable 
it to pass on such matters.  In giving such opinion, Bryan Cave LLP may rely 
as to matters of fact upon statements and certifications of officers of the 
Offerors and of other appropriate persons and may rely as to matters of law, 
other than law of the United States and the State of Missouri, upon the 
opinion of [GREENEBAUM, DOLL & MCDONALD] [DAVID W. HARPER, ESQ.] and 
Richards, Layton and Finger described herein.
         
         (g)  On the date of this Agreement and on the Closing Date (and, if 
applicable, any Option Closing Date), the Underwriter shall have received 
from Geo. S. Olive & Co. a letter, dated the date of this Agreement and the 
Closing Date (and, if applicable, the Option Closing Date), respectively, in 
form and substance satisfactory to the Underwriter, confirming that it is an 
independent public accounting firm with respect to the Company and the 
Subsidiaries (for purposes of this Section 6(g) the "Company") within the 
meaning of the 1933 Act and the 1933 Act Regulations, and stating in effect 
that:
         
              (i)   In its opinion, the consolidated financial statements of the
    Company audited by it and included in the Registration Statement comply as
    to form in all material respects with the applicable accounting
    requirements of the 1933 Act and the 1933 Act Regulations. 
              
              (ii)  On the basis of the procedures specified by the American
    Institute of Certified Public Accountants as described in SAS No. 71,
    "Interim Financial Information," inquiries of officials of the Company
    responsible for financial and accounting matters, and such other inquiries
    and procedures as may be specified in such letter, which procedures do not
    constitute an audit in accordance with U.S. generally accepted auditing
    standards, nothing came to its attention that caused it to believe that, if
    applicable, the unaudited interim consolidated financial statements of the
    Company included in the Registration Statement do not comply as to form in
    all material respects with the applicable accounting requirements of the
    1933 Act and 1933 Act Regulations or are not in conformity with U.S.
    generally accepted accounting principles applied on a basis substantially
    consistent, except as noted in the Registration Statement, with the basis
    for the audited consolidated financial statements of the Company included
    in the Registration Statement.
              
              (iii) On the basis of limited procedures, not constituting an
    audit in accordance with U.S. generally accepted auditing standards,
    consisting of a reading of the unaudited interim financial statements and
    other information referred to below, a reading of the latest available
    unaudited condensed consolidated financial statements of the Company,
    inspection of the minute books of the Company since the date of the latest
    audited financial statements of the Company included or incorporated by
    reference in the Registration Statement, inquiries of officials of the
    Company responsible for financial and accounting matters and such other
    inquiries and procedures as may be specified in such letter, nothing came
    to its attention that caused it to believe that:

                                       22
<PAGE>

                   (A)  as of a specified date not more than five days prior to
         the date of such letter, there have been any changes in the
         consolidated capital stock of the Company, any increase in the
         consolidated debt of the Company, any decreases in consolidated total
         assets or shareholders equity of the Company, or any changes,
         decreases or increases in other items specified by the Underwriter, in
         each case as compared with amounts shown in the latest unaudited
         interim consolidated statement of financial condition of the Company
         included in the Registration Statement except in each case for
         changes, increases or decreases which the Registration Statement
         specifically discloses, have occurred or may occur or which are
         described in such letter; and
                   
                   (B)  for the period from the date of the latest unaudited
         interim consolidated financial statements of the Company included in
         the Registration Statement to the specified date referred to in Clause
         (iii)(A), there were any decreases in the consolidated interest
         income, net interest income, or net income of the Company or in the
         per share amount of net income of the Company, or any changes,
         decreases or increases in any other items specified by the
         Underwriter, in each case as compared with the comparable period of
         the preceding year and with any other period of corresponding length
         specified by the Underwriter, except in each case for increases or
         decreases which the Registration Statement discloses have occurred or
         may occur, or which are described in such letter;
              
              (iv) In addition to the audit referred to in its report included
    in the Registration Statement and the limited procedures, inspection of
    minute books, inquiries and other procedures referred to in paragraphs (ii)
    and (iii) above, it has carried out certain specified procedures, not
    constituting an audit in accordance with U.S. generally accepted auditing
    standards, with respect to certain amounts, percentages and financial
    information specified by the Underwriter which are derived from the general
    accounting records and consolidated financial statements of the Company
    which appear in the Registration Statement, and have compared such amounts,
    percentages and financial information with the accounting records and the
    material derived from such records and consolidated financial statements of
    the Company and have found them to be in agreement.
              
         In the event that the letters to be delivered referred to above set 
forth any such changes, decreases or increases as specified in Clauses 
(iii)(A) or (iii)(B), above, or any exceptions from such agreement specified 
in Clause (iv) above, it shall be a further condition to the Underwriter's 
obligations that the Underwriter shall have determined, after discussions 
with officers of the Company, responsible for financial and accounting 
matters, that such changes, decreases, increases or exceptions as are set 
forth in such letters do not (x) reflect a material adverse change in the 
items specified in Clause (iii)(A) above as compared with the amounts shown 
in the latest unaudited consolidated statement of financial condition of the 
Company included in the Registration Statement, (y) reflect a material 
adverse change in the items specified in Clause (iii)(B) above as compared 
with the corresponding periods of the prior year or other period specified by 
the Underwriter, or (z) reflect a material change in items specified in 
Clause (iv) above from the amounts shown in the Preliminary Prospectus 
distributed by the Underwriter in connection with the offering contemplated 
hereby or from the amounts shown in the Prospectus.
         
         (h)  On the date of this Agreement and on the Closing Date (and, if 
applicable, any Option Closing Date), the Underwriter shall have received 
from Crowe, Chizek and Company LLP a letter, dated the date of this Agreement 
and the Closing Date (and, if applicable, the Option Closing Date), 
respectively, in form and substance satisfactory to the Underwriter, 
confirming that it is an independent public accounting firm with respect to 
PTC within the meaning of the 1933 Act and the 1933 Act Regulations, and 
stating in effect that:

                                      23
<PAGE>

              (i)   In its opinion, the consolidated financial statements of PTC
    audited by it and included in the Registration Statement comply as to form
    in all material respects with the applicable accounting requirements of the
    1933 Act and the 1933 Act Regulations. 
              
              (ii)  On the basis of the procedures specified by the American
    Institute of Certified Public Accountants as described in SAS No. 71,
    "Interim Financial Information," inquiries of officials of PTC responsible
    for financial and accounting matters, and such other inquiries and
    procedures as may be specified in such letter, which procedures do not
    constitute an audit in accordance with U.S. generally accepted auditing
    standards, nothing came to its attention that caused it to believe that, if
    applicable, the unaudited interim consolidated financial statements of PTC
    included in the Registration Statement do not comply as to form in all
    material respects with the applicable accounting requirements of the 1933
    Act and 1933 Act Regulations or are not in conformity with U.S. generally
    accepted accounting principles applied on a basis substantially consistent,
    except as noted in the Registration Statement, with the basis for the
    audited consolidated financial statements of PTC included in the
    Registration Statement.
              
              (iii) On the basis of limited procedures, not constituting an
    audit in accordance with U.S. generally accepted auditing standards,
    consisting of a reading of the unaudited interim financial statements and
    other information referred to below, a reading of the latest available
    unaudited condensed consolidated financial statements of PTC, inspection of
    the minute books of PTC since the date of the latest audited financial
    statements of PTC included or incorporated by reference in the Registration
    Statement, inquiries of officials of PTC responsible for financial and

    specified in such letter, nothing came to its attention that caused it to
    believe that:
                   
                   (A)  as of a specified date not more than five days prior to
         the date of such letter, there have been any changes in the

         other items specified by the Underwriter, in each case as compared
         with amounts shown in the latest unaudited interim consolidated
         statement of financial condition of PTC included in the Registration
         Statement except in each case for changes, increases or decreases
         which the Registration Statement specifically discloses, have occurred
         or may occur or which are described in such letter; and
                   
                   (B)  for the period from the date of the latest unaudited
         interim consolidated financial statements of PTC included in the
         Registration Statement to the specified date referred to in Clause
         (iii)(A), there were any decreases in the consolidated interest

         period of corresponding length specified by the Underwriter, except in
         each case for increases or decreases which the Registration Statement
         discloses have occurred or may occur, or which are described in such
         letter;
              
              (iv)  In addition to the audit referred to in its report included
    in the Registration Statement and the limited procedures, inspection of
    minute books, inquiries and other procedures referred to in paragraphs (ii)
    and (iii) above, it has carried out certain specified procedures, not
    constituting an audit in accordance with U.S. generally accepted auditing
    standards, with respect to certain amounts, percentages and financial
    information specified by the Underwriter which are derived from the general
    accounting records and

<PAGE>

    consolidated financial statements of PTC which appear in the Registration 
    Statement, and have compared such amounts, percentages and financial 
    information with the accounting records and the material derived from such 
    records and consolidated financial statements of PTC and have found them to
    be in agreement.
              
         In the event that the letters to be delivered referred to above set 
forth any such changes, decreases or increases as specified in Clauses 
(iii)(A) or (iii)(B), above, or any exceptions from such agreement specified 
in Clause (iv) above, it shall be a further condition to the Underwriter's 
obligations that the Underwriter shall have determined, after discussions

letters do not (x) reflect a material adverse change in the items specified 
in Clause (iii)(A) above as compared with the amounts shown in the latest 
unaudited consolidated statement of financial condition of PTC included in 
the Registration Statement, (y) reflect a material adverse change in the 
items specified in Clause (iii)(B) above as compared with the corresponding

of the Offerors and the Subsidiaries on a consolidated basis; (iii) since 
such dates there has not been any material transaction entered into by the 
Offerors or the Subsidiaries other than transactions in the ordinary course 
of business; and (iv) each such officer has carefully examined the 
Registration Statement and the Prospectus as amended or supplemented and 
nothing has come to his or her attention that would lead him or her to 
believe that either the Registration Statement or the Prospectus, or any 
amendment or supplement thereto as of their respective effective or issue 
dates, contained, and the Prospectus as amended or supplemented at such 
Closing Date (and, if applicable, the Option Closing Date), contains any 
untrue statement of a material fact, or omits to state a material fact 
required to be stated therein or necessary in order to make the statements 
therein, in the light of the circumstances under which they were made, not 
misleading; and (v) covering such other matters as the Underwriter may 
reasonably request.  The officers' certificate of the Company shall further 
state that no stop order affecting the Registration Statement is in effect or 
threatened.
         
         (j)  At the Closing Date and, if applicable, the Option Closing 
Date, the Underwriter shall have received a certificate of an authorized 
representative of the Trust to the effect that to the best of his or her 
knowledge based upon a reasonable investigation, the representations and 
warranties of the Trust in this Agreement are true and correct as though made 
on and as of the Closing Date (and, if applicable, the Option Closing Date); 
the Trust has complied with all the agreements and satisfied all the 
conditions required by this Agreement to be performed or satisfied by the 
Trust on or prior to the Closing Date and since the most recent date as of 
which information is given in the Prospectus, except as contemplated by the

obligations, direct or contingent, or entered into any material transactions 
not in the ordinary course of business and there has not been any material 
adverse change in the condition (financial or otherwise) of the Trust.

         (k)  On the Closing Date, the Underwriter shall have received duly 
executed counterparts of the Trust Agreement, the Guarantee, the Indenture 
and the Expense Agreement.
         
         (l)  The NASD, upon review of the terms of the public offering of

         (m)  Prior to the Closing Date and, if applicable, the Option 
Closing Date, the Offerors shall have furnished to the Underwriter and its 
counsel all such other documents, certificates and opinions as they have 
reasonably requested.
         
         All opinions, certificates, letters and other documents shall be in 
compliance with the provisions hereof only if they are reasonably 
satisfactory in form and substance to the Underwriter and its counsel.  The 
Offerors shall furnish the Underwriter with conformed copies of such 
opinions, certificates, letters and other documents as the Underwriter shall 
reasonably request.
         
         If any of the conditions referred to in this Section 6 shall not 
have been fulfilled when and as required by this Agreement, this Agreement 
and all of the Underwriter's obligations hereunder may be terminated by the 
Underwriter on notice to the Company at, or at any time before, the Closing 
Date or the Option Closing Date, as applicable.  Any such termination shall 
be without liability of the Underwriter to the Offerors.
         
    7.   INDEMNIFICATION AND CONTRIBUTION.
         
         (a)  The Offerors agree to jointly and severally indemnify and hold 
harmless the Underwriter, each of its directors, officers and agents, and 
each person, if any, who controls the Underwriter within the meaning of the 
1933 Act, against any and all losses, claims, damages, liabilities and 
expenses (including reasonable costs of investigation and reasonable 
attorneys' fees and expenses), joint or several, arising out of or based (i) 
upon any untrue statement or alleged untrue statement of a material fact made 
by the Company or the Trust contained in Section 2(a) of this Agreement (or 
any certificate delivered by the Company or the Trust pursuant to Sections 
6(h), 6(i) or 6(l) hereof) or the registration statement as originally filed 
or the Registration Statement, any Preliminary Prospectus or the Prospectus, 
or in any amendment or supplement thereto, (ii) upon any blue sky application 
or other document executed by the Company or the Trust specifically for that 
purpose or based upon written information furnished by the Company or the 
Trust filed in any state or other jurisdiction in order to qualify any of the 
Designated Preferred Securities under the securities laws thereof (any such 
application, document or information being hereinafter referred to as a "Blue 
Sky Application"), (iii) any omission or alleged omission to state a material 
fact in the registration statement as originally filed or the Registration 
Statement, the Preliminary Prospectus or the Prospectus, or in any amendment 
or supplement thereto, or in any Blue Sky Application required to be stated 
therein or necessary to make the statements therein not misleading, and 
against any and all losses, claims, damages, liabilities and expenses 
(including reasonable costs of investigation and attorneys' fees), joint or 
several, arising out of or based upon any untrue statement or alleged untrue 
statement of a material fact contained in any Preliminary Prospectus or the 
Prospectus, or in any amendment or supplement thereto, or arising out of or 
based upon any omission or alleged omission to state therein 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 or 
(iv) the enforcement of this indemnification provision or the contribution 
provisions of Section 7(d); and shall reimburse each such indemnified party 
for any reasonable legal or other expenses as incurred, but in no event less 
frequently than 30 days after each invoice is submitted, incurred by them in 
connection with investigating or defending against or appearing as a 
third-party witness in connection with any such loss, claim, damage, 
liability or action, notwithstanding the possibility that payments for such 
expenses might later be held to be improper, in which case such payments 
shall be promptly refunded; provided, however, that the Offerors shall 

                                       26
<PAGE>

not be liable in any case to the extent, but only to the extent, that any 
such losses, claims, damages, liabilities and expenses arise out of or are 
based upon any untrue statement or omission or allegation thereof that has 
been made therein or omitted therefrom in reliance upon and in conformity 
with the information relating to the Underwriter furnished in writing to an 
Offeror through the Underwriter by or on behalf of it expressly for use in 
connection with the Registration Statement, the Preliminary Prospectus or the 
Prospectus, or in any amendment or supplement thereto; provided, that the 
indemnification contained in this paragraph with respect to any Preliminary 
Prospectus shall not inure to the benefit of the Underwriter (or of any 
person controlling the Underwriter) to the extent any such losses, claims, 
damages, liabilities or expenses directly results from the fact that the 
Underwriter sold Designated Preferred Securities to a person to whom there 
was not sent or given, at or prior to the written confirmation of such sale, 
a copy of the Prospectus (as amended or supplemented if any amendments or 
supplements thereto shall have been furnished to the Underwriter in 
sufficient time to distribute same with or prior to the written confirmation 
of the sale involved), if required by law, and if such loss, claim, damage, 
liability or expense would not have arisen but for the failure to give or 
send such person such document.  The foregoing indemnity agreement is in 
addition to any liability the Company or the Trust may otherwise have to any 
such indemnified party.
         
         (b)  The Underwriter agrees to indemnify and hold harmless each 
Offeror, each of its directors, each of its officers who signed the 
Registration Statement and each person, if any, who controls an Offeror 
within the meaning of the 1933 Act, to the same extent as required by the 
foregoing indemnity from the Company to the Underwriter, but only with 
respect to the information related to the Underwriter furnished in writing to 
an Offeror through the Underwriter by or on its behalf expressly for use in a 
Blue Sky Application.  The foregoing indemnity agreement is in addition to 
any liability which the Underwriter may otherwise have to any such 
indemnified party.

         (c)  If any action or claim shall be brought or asserted against any 
indemnified party or any person controlling an indemnified party in respect 
of which indemnity may be sought from the indemnifying party, such 
indemnified party or controlling person shall promptly notify the 
indemnifying party in writing, and the indemnifying party shall assume the 
defense thereof, including the employment of counsel reasonably satisfactory 
to the indemnified party and the payment of all expenses; PROVIDED, HOWEVER, 
that the failure so to notify the indemnifying party shall not relieve it 
from any liability which it may have to an indemnified party otherwise than 
under such paragraph, and further, shall only relieve it from liability under 
such paragraph to the extent prejudiced thereby.  Any indemnified party or 
any such controlling person shall have the right to employ separate counsel 
in any such action and to participate in the defense thereof, but the fees 
and expenses of such counsel shall be at the expense of such indemnified 
party or such controlling person unless (i) the employment thereof has been 
specifically authorized by the indemnifying party in writing, (ii) the 
indemnifying party has failed to assume the defense or to employ counsel 
reasonably satisfactory to the indemnified party or (iii) the named parties 
to any such action (including any impleaded parties) include both such 
indemnified party or such controlling person and the indemnifying party and 
such indemnified party or such controlling person shall have been advised by 
such counsel that there may be one or more legal defenses available to it 
that are different from or in addition to those available to the indemnifying 
party (in which case, if such indemnified party or controlling person 
notifies the indemnifying party in writing that it elects to employ separate 
counsel at the expense of the indemnifying party, the indemnifying party 
shall not have the right to assume the defense of such action on behalf of 
such indemnified party or such controlling person) it being understood, 
however, that the indemnifying party shall not, in connection with any one 
such action or separate but substantially similar or related actions in the 
same jurisdiction arising out of the same general allegations or 
circumstances, be liable for the reasonable fees and expenses of more than 
one separate firm of attorneys at any time and for all such indemnified 
parties and controlling persons, which firm shall be designated in writing by 
the indemnified party.  Each indemnified party and each controlling person, 
as a condition of such indemnity, shall use reasonable efforts to cooperate 
with the indemnifying party in 

                                      27
<PAGE>

the defense of any such action or claim.  The indemnifying party shall not be 
liable for any settlement of any such action effected without its written 
consent, but if there be a final judgment for the plaintiff in any such 
action, the indemnifying party agrees to indemnify and hold harmless any 
indemnified party and any such controlling person from and against any loss, 
claim, damage, liability or expense by reason of such settlement or judgment.

         An indemnifying party shall not, without the prior written consent 
of each indemnified party, settle, compromise or consent to the entry of any 
judgment in any pending or threatened claim, action, suit or proceeding in 
respect of which indemnity may be sought hereunder (whether or not such 
indemnified party or any person who controls such indemnified party within 
the meaning of the 1933 Act is a party to such claim, action, suit or 
proceeding), unless such settlement, compromise or consent includes a release 
of each such indemnified party reasonably satisfactory to each such 
indemnified party and each such controlling person from all liability arising 
out of such claim, action, suit or proceeding or unless the indemnifying 
party shall confirm in a written agreement with each indemnified party, that 
notwithstanding any federal, state or common law, such settlement, compromise 
or consent shall not alter the right of any indemnified party or controlling 
person to indemnification or contribution as provided in this Agreement.
         
         (d)  If the indemnification provided for in this Section 7 is 
unavailable or insufficient to hold harmless an indemnified party under 
paragraphs (a), (b) or (c) hereof in respect of any losses, claims, damages, 
liabilities or expenses referred to therein, then each indemnifying party, in 
lieu of indemnifying such indemnified party, shall contribute to the amount 
paid or payable by such indemnified party as a result of such losses, claims, 
damages, liabilities or expenses (i) in such proportion as is appropriate to 
reflect the relative benefits received by the Offerors on the one hand and 
the Underwriter on the other from the offering of the Designated Preferred 
Securities or (ii) if the allocation provided by clause (i) above is not 
permitted by applicable law, in such proportion as is appropriate to reflect 
not only the relative benefits referred to in clause (i) above but also the 
relative fault of the Offerors on the one hand and the Underwriter on the 
other in connection with the statements or omissions that resulted in such 
losses, claims, damages, liabilities or expenses, as well as any other 
relevant equitable considerations.  The benefits received by the Underwriter 
on the one hand and the Offerors on the other shall be deemed to be allocated 
pro rata on the basis of the total underwriting discounts, commissions and 
compensation received by the Underwriter relative to the total net proceeds 
from the offering of the Designated Preferred Securities (before deducting 
expenses) received by the Offerors, in each case as set forth in the table on 
the cover page of the Prospectus.  The relative fault of the Offerors on the 
one hand and of the Underwriter on the other 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 Offerors or by the Underwriter and the 
parties' relative intent, knowledge, access to information and opportunity to 
correct or prevent such untrue statement or omission.  Each Offeror and the 
Underwriter agree that it would not be just and equitable if contribution 
pursuant to this paragraph (d) were determined by pro rata allocation or by 
any other method of allocation that does not take into account the equitable 
considerations referred to herein.  The amount paid or payable by an 
indemnified party as a result of the losses, claims, damages, liabilities and 
expenses referred to in the first sentence of this paragraph (d) shall be 
deemed to include, subject to the limitations set forth above, any legal or 
other expenses reasonably incurred by such indemnified party in connection 
with investigating or defending any such action or claim. Notwithstanding the 
provisions of this paragraph (d), the Underwriter shall not be required to 
contribute any amount in excess of the amount by which the total price at 
which the Designated Preferred Securities underwritten by the Underwriter and 
distributed to the public exceeds the amount of any damages that the 
Underwriter has otherwise been required to pay by reason of such untrue or 
alleged untrue statement or omission or alleged omission.  No person guilty 
of fraudulent misrepresentation (within the meaning of Section 11(f) of the 
1933 Act) shall be entitled to contribution from any person who was not 
guilty of such fraudulent misrepresentation.  

                                      28
<PAGE>

         For purposes of this paragraph (d), each person who controls the 
Underwriter within the meaning of the 1933 Act shall have the same rights to 
contribution as the Underwriter, and each person who controls an Offeror 
within the meaning of the 1933 Act, each officer and trustee of an Offeror 
who shall have signed the Registration Statement and each director of an 
Offeror shall have the same rights to contribution as the Offerors subject in 
each case to the preceding paragraph.  The obligations of the Offerors under 
this paragraph (d) shall be in addition to any liability which the Offerors 
may otherwise have and the obligations of the Underwriter under this 
paragraph (d) shall be in addition to any liability that the Underwriter may 
otherwise have.
         
         (e)  The indemnity and contribution agreements contained in this 
Section 7 and the representations and warranties of the Offerors set forth in 
this Agreement shall remain operative and in full force and effect, 
regardless of (i) any investigation made by or on behalf of the Underwriter 
or any person controlling the Underwriter or by or on behalf of the Offerors, 
or such directors, trustees or officers (or any person controlling an 
Offeror), (ii) acceptance of any Designated Preferred Securities and payment 
therefor hereunder and (iii) any termination of this Agreement.  A successor 
of the Underwriter or of an Offeror, such directors, trustees or officers (or 
of any person controlling the Underwriter or an Offeror) shall be entitled to 
the benefits of the indemnity, contribution and reimbursement agreements 
contained in this Section 7.
         
         (f)  The Company agrees to indemnify the Trust against any and all 
losses, claims, damages or liabilities that may become due from the Trust 
under this Section 7.
    
    8.   TERMINATION.  The Underwriter shall have the right to terminate this 
Agreement at any time at or prior to the Closing Date or, with respect to the 
Underwriter's obligation to purchase the Option Preferred Securities, at any 
time at or prior to the Option Closing Date, without liability on the part of 
the Underwriter to the Offerors, if:
         
         (a)  Either Offeror shall have failed, refused, or been unable to 
perform any agreement on its part to be performed under this Agreement, or 
any of the conditions referred to in Section 6 shall not have been fulfilled, 
when and as required by this Agreement;
         
         (b)  The Offerors or any of the Subsidiaries shall have sustained 
any material loss or interference with its business from fire, explosion, 
flood or other calamity, whether or not covered by insurance, or from any 
labor dispute or court or governmental action, order or decree which in the 
judgment of the Underwriter materially impairs the investment quality of the 
Designated Preferred Securities;
         
         (c)  There has been since the respective dates as of which 
information is given in the Registration Statement or the Prospectus, any 
materially adverse change in, or any development which is reasonably likely 
to have a material adverse effect on, the condition (financial or otherwise), 
earnings, affairs, business, prospects or results of operations of the 
Offerors and the Subsidiaries on a consolidated basis, whether or not arising 
in the ordinary course of business;
         
         (d)  There has occurred any outbreak of hostilities or other 
calamity or crisis or material change in general economic, political or 
financial conditions, or internal conditions, the effect of which on the 
financial markets of the United States is such as to make it, in the 
Underwriter's reasonable judgment, impracticable to market the Designated 
Preferred Securities or enforce contracts for the sale of the Designated 
Preferred Securities;
         
         (e)  Trading generally on the New York Stock Exchange, the American 
Stock Exchange or the Nasdaq National Market shall have been suspended, or 
minimum or maximum prices for trading shall have been fixed, or maximum 
ranges for prices for securities shall have been required, by any of said 
exchanges or market system or by the Commission or any other governmental 
authority;

                                      29
<PAGE>

         (f)  A banking moratorium shall have been declared by either federal 
or Indiana authorities; or

         (g)  Any action shall have been taken by any government in respect 
of its monetary affairs which, in the Underwriter's reasonable judgment, has 
a material adverse effect on the United States securities markets.

         The Offerors shall have the right to terminate this Agreement at any 
time at or prior to the Closing Date or, with respect to the sale of the 
Option Preferred Securities, at any time at or prior to the Option Closing 
Date, if a Tax Event or a Capital Treatment Event, as such terms are defined 
in the Registration Statement, shall have occurred.
         
         If this Agreement shall be terminated pursuant to this Section 8, 
the Offerors shall not then be under any liability to the Underwriter except 
as provided in Sections 5 and 7 hereof.
    
    9.   EFFECTIVE DATE OF AGREEMENT.  If the Registration Statement is not 
effective at the time of execution of this Agreement, this Agreement shall 
become effective on the Effective Date at the time the Commission declares 
the Registration Statement effective.  The Company shall immediately notify 
the Underwriter when the Registration Statement becomes effective.
         
         If the Registration Statement is effective at the time of execution 
of this Agreement, this Agreement shall become effective at the earlier of 
11:00 a.m. St. Louis time, on the first full business day following the day 
on which this Agreement is executed, or at such earlier time as the 
Underwriter shall release the Designated Preferred Securities for initial 
public offering.  The Underwriter shall notify the Offerors immediately after 
it has taken any action which causes this Agreement to become effective. 
         
         Until such time as this Agreement shall have become effective, it 
may be terminated by the Offerors, by notifying the Underwriter, or by the 
Underwriter, by notifying either Offeror, except that the provisions of 
Sections 5 and 7 shall at all times be effective.
    
    10.  REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.  The 
representations, warranties, indemnities, agreements and other statements of 
the Offerors and their officers and trustees set forth in or made pursuant to 
this Agreement and the agreements of the Underwriter contained in Section 7 
hereof shall remain operative and in full force and effect regardless of any 
investigation made by or on behalf of the Offerors or controlling persons of 
either Offeror, or by or on behalf of the Underwriter or controlling persons 
of the Underwriter or any termination or cancellation of this Agreement and 
shall survive delivery of and payment for the Designated Preferred Securities.
    
    11.  NOTICES.  Except as otherwise provided in this Agreement, all 
notices and other communications hereunder shall be in writing and shall be 
deemed to have been duly given if delivered by hand, mailed by registered or

Debentures and thereupon any or all temporary Debentures may be surrendered 
in exchange therefor (without charge to the holders), at the office or agency 
of the Company designated for the purpose in the Borough of Manhattan, the 
City of New York, and the Trustee shall authenticate and such office or 
agency shall deliver in exchange for such temporary Debentures an equal 
aggregate principal amount of definitive Debentures, unless the Company 
advises the Trustee to the effect that definitive Debentures need not be 
executed and furnished until further notice from the Company. Until so 
exchanged, the temporary Debentures shall be entitled to the same benefits 
under this Indenture as definitive Debentures authenticated and delivered 
hereunder.

SECTION 2.9. MUTILATED, DESTROYED, LOST OR STOLEN DEBENTURES.

   (a) In case any temporary or definitive Debenture shall become mutilated 
or be destroyed, lost or stolen, the Company (subject to the next succeeding 
sentence) shall execute, and upon the Company's request the Trustee (subject 
as aforesaid) shall authenticate and deliver, a new Debenture bearing a 
number not contemporaneously outstanding, in exchange and substitution for 
the mutilated Debenture, or in lieu of and in substitution for the Debenture 
so destroyed, lost or stolen. In every case the applicant for a substituted 
Debenture shall furnish to the Company and the Trustee such security or 
indemnity as may be required by them to save each of them harmless, and, in 
every case of destruction, loss or theft, the applicant shall also furnish to 
the Company and the Trustee evidence to their satisfaction of the 
destruction, loss or theft of the applicant's Debenture and of the ownership 
thereof. The Trustee shall authenticate any such substituted Debenture and 
deliver the same upon the written request or authorization of the Chairman, 
President or any Vice President and the Treasurer or any Assistant Treasurer 
of the Company. Upon the issuance of any substituted Debenture, the Company 
may require the payment of a sum sufficient to cover any tax or other 
governmental charge that may be imposed in relation thereto and any other 
expenses (including the fees and expenses of the Trustee) connected 
therewith. In case any Debenture that has matured or is about to mature shall 
become mutilated or be destroyed, lost or stolen, the Company may, instead of 
issuing a substitute Debenture, pay or authorize the payment of the same 
(without surrender thereof except in the case of a mutilated Debenture) if 
the applicant for such payment shall furnish to the Company and the Trustee 
such security or indemnity as they may require to save them harmless, and, in 
case of destruction, loss or theft, evidence to the satisfaction of the 
Company and the Trustee of the destruction, loss or theft of such Debenture 
and of the ownership thereof.

                                      14
<PAGE>

   (b) Every replacement Debenture issued pursuant to the provisions of this 
Section 2.9 shall constitute an additional contractual obligation of the 
Company whether or not the mutilated, destroyed, lost or stolen Debenture 
shall be found at any time, or be enforceable by anyone, and shall be 
entitled to all the benefits of this Indenture equally and proportionately 
with any and all other Debentures duly issued hereunder. All Debentures shall 
be held and owned upon the express condition that the foregoing provisions 
are exclusive with respect to the replacement or payment of mutilated, 
destroyed, lost or stolen Debentures, and shall preclude (to the extent 
lawful) any and all other rights or remedies, notwithstanding any law or 
statute existing or hereafter enacted to the contrary with respect to the 
replacement or payment of negotiable instruments or other securities without 
their surrender.

SECTION 2.10. CANCELLATION.

   All Debentures surrendered for the purpose of payment, redemption, 
exchange or registration of transfer shall, if surrendered to the Company or 
any Paying Agent, be delivered to the Trustee for cancellation, or, if 
surrendered to the Trustee, shall be canceled by it, and no Debentures shall 
be issued in lieu thereof except as expressly required or permitted by any of 
the provisions of this Indenture. On request of the Company at the time of 
such surrender, the Trustee shall deliver to the Company canceled Debentures 
held by the Trustee. In the absence of such request the Trustee may dispose 
of canceled Debentures in accordance with its standard procedures and deliver 
a certificate of disposition to the Company. If the Company shall otherwise 
acquire any of the Debentures, however, such acquisition shall not operate as 
a redemption or satisfaction of the indebtedness represented by such 
Debentures unless and until the same are delivered to the Trustee for 
cancellation.

SECTION 2.11. BENEFIT OF INDENTURE.

   Nothing in this Indenture or in the Debentures, express or implied, shall 
give or be construed to give to any Person, other than the parties hereto and 
the holders of the Debentures (and, with respect to the provisions of Article 
XVI, the holders of the Senior Indebtedness) any legal or equitable right, 
remedy or claim under or in respect of this Indenture, or under any covenant, 
condition or provision herein contained; all such covenants, conditions and 
provisions being for the sole benefit of the parties hereto and of the 
holders of the Debentures (and, with respect to the provisions of Article 
XVI, the holders of the Senior Indebtedness).

SECTION 2.12. AUTHENTICATION AGENT.

   (a) So long as any of the Debentures remain Outstanding there may be an 
Authenticating Agent for any or all such Debentures, which the Trustee shall 
have the right to appoint. Said Authenticating Agent shall be authorized to 
act on behalf of the Trustee to authenticate Debentures issued upon exchange, 
transfer or partial redemption thereof, and Debentures so authenticated shall 
be entitled to the benefits of this Indenture and shall be valid and 
obligatory for all purposes as if authenticated by the Trustee hereunder. All 
references in this Indenture to the authentication of Debentures by the 
Trustee shall be deemed to include authentication by an Authenticating Agent. 
Each Authenticating Agent shall be acceptable to the Company and shall be a 
corporation that has a combined capital and surplus, as most recently 
reported or determined 

                                      15
<PAGE>

by it, sufficient under the laws of any jurisdiction under which it is 
organized or in which it is doing business to conduct a trust business, and 
that is otherwise authorized under such laws to conduct such business and is 
subject to supervision or examination by federal or state authorities. If at 
any time any Authenticating Agent shall cease to be eligible in accordance 
with these provisions, it shall resign immediately.

   (b) Any Authenticating Agent may at any time resign by giving written 
notice of resignation to the Trustee and to the Company. The Trustee may at 
any time (and upon request by the Company shall) terminate the agency of any 
Authenticating Agent by giving written notice of termination to such 
Authenticating Agent and to the Company. Upon resignation, termination or 
cessation of eligibility of any Authenticating Agent, the Trustee may appoint 
an eligible successor Authenticating Agent acceptable to the Company. Any 
successor Authenticating Agent, upon acceptance of its appointment hereunder, 
shall become vested with all the rights, powers and duties of its predecessor 
hereunder as if originally named as an Authenticating Agent pursuant hereto.
                                       
                                  ARTICLE III.
                            REDEMPTION OF DEBENTURES
                                       
SECTION 3.1. REDEMPTION.

   Subject to the Company having received prior approval of the Federal 
Reserve, if then required under the applicable capital guidelines or policies 
of the Federal Reserve, the Company may redeem the Debentures issued 
hereunder on and after the dates set forth in and in accordance with the 
terms of this Article III.

SECTION 3.2. SPECIAL EVENT REDEMPTION.

   Subject to the Company having received the prior approval of the Federal 
Reserve, if then required under the applicable capital guidelines or policies 
of the Federal Reserve, if a Special Event has occurred and is continuing, 
then, notwithstanding Section 3.3(a) but subject to Section 3.3(b), the 
Company shall have the right upon not less than 30 days' nor more than 60 
days' notice to the holders of the Debentures to redeem the Debentures, in 
whole but not in part, for cash within 180 days following the occurrence of 
such Special Event (the "180-Day Period") at a redemption price equal to 100% 
of the principal amount to be redeemed plus any accrued and unpaid interest 
thereon to the date of such redemption (the "Redemption Price"), provided 
that if at the time there is available to the Company the opportunity to 
eliminate, within the 180-Day Period, a Tax Event by taking some ministerial 
action (a "Ministerial Action"), such as filing a form or making an election, 
or pursuing some other similar reasonable measure which has no adverse effect 
on the Company, the Trust or the holders of the Trust Securities issued by 
the Trust, the Company shall pursue such Ministerial Action in lieu of 
redemption, and, provided further, that the Company shall have no right to 
redeem the Debentures while it is pursuing any Ministerial Action pursuant to 
its obligations hereunder. The Redemption Price shall be paid prior to 12:00 
noon, New York time, on the date of such redemption or such earlier time as 
the Company determines, provided that the Company shall deposit with the 
Trustee an amount 

                                      16
<PAGE>

sufficient to pay the Redemption Price by 10:00 a.m., New York time, on the 
date such Redemption Price is to be paid.

SECTION 3.3. OPTIONAL REDEMPTION BY THE COMPANY.

   (a) Subject to the provisions of Section 3.3(b), except as otherwise may 
be specified in this Indenture, the Company shall have the right to redeem 
the Debentures, in whole or in part, from time to time, on or after December 
30, 2002, at a Redemption Price equal to 100% of the principal amount to be 
redeemed plus any accrued and unpaid interest thereon to the date of such 
redemption, plus Deferred Payments, if any. Any redemption pursuant to this 
Section 3.3(a) shall be made upon not less than 30 days' nor more than 60 
days' notice to the holder of the Debentures, at the Redemption Price. If the 
Debentures are only partially redeemed pursuant to this Section 3.3, the 
Debentures shall be redeemed pro rata or by lot or in such other manner as 
the Trustee shall deem appropriate and fair in its discretion. The Redemption 
Price shall be paid prior to 12:00 noon, New York time, on the date of such 
redemption or at such earlier time as the Company determines provided that 
the Company shall deposit with the Trustee an amount sufficient to pay the 
Redemption Price by 10:00 a.m., New York time, on the date such Redemption 
Price is to be paid.

   (b) If a partial redemption of the Debentures would result in the 
delisting of the Preferred Securities issued by the Trust from the Nasdaq 
National Market or any national securities exchange or other organization on 
which the Preferred Securities are then listed or quoted, the Company shall 
not be permitted to effect such partial redemption and may only redeem the 
Debentures in whole.

SECTION 3.4. NOTICE OF REDEMPTION.

   (a) In case the Company shall desire to exercise such right to redeem all 
or, as the case may be, a portion of the Debentures in accordance with the 
right reserved so to do, the Company shall, or shall cause the Trustee to 
upon receipt of 45 days' written notice from the Company (which notice shall, 
in the event of a partial redemption, include a representation to the effect 
that such partial redemption shall not result in the delisting of the 
Preferred Securities as described in Section 3.3(b) above), give notice of 
such redemption to holders of the Debentures to be redeemed by mailing, first 
class postage prepaid, a notice of such redemption not less than 30 days' and 
not more than 60 days' before the date fixed for redemption to such holders 
at their last addresses as they shall appear upon the Debenture Register 
unless a shorter period is specified in the Debentures to be redeemed. Any 
notice that is mailed in the manner herein provided shall be conclusively 
presumed to have been duly given, whether or not the registered holder 
receives the notice. In any case, failure duly to give such notice to the 
holder of any Debenture designated for redemption in whole or in part, or any 
defect in the notice, shall not affect the validity of the proceedings for 
the redemption of any other Debentures. In the case of any redemption of 
Debentures prior to the expiration of any restriction on such redemption 
provided in the terms of such Debentures or elsewhere in this Indenture, the 
Company shall furnish the Trustee with an Officers' Certificate evidencing 
compliance with any such restriction. Each such notice of redemption shall 
specify the date fixed for redemption and the Redemption Price and shall 
state 

                                      17
<PAGE>

that payment of the Redemption Price shall be made at the office or agency of 
the Company in the Borough of Manhattan, the City of New York or at the 
Corporate Trust Office, upon presentation and surrender of such Debentures, 
that interest accrued to the date fixed for redemption shall be paid as 
specified in said notice and that from and after said date interest shall 
cease to accrue. If less than all the Debentures are to be redeemed, the 
notice to the holders of the Debentures shall specify the particular 
Debentures to be redeemed. If the Debentures are to be redeemed in part only, 
the notice shall state the portion of the principal amount thereof to be 
redeemed and shall state that on and after the redemption date, upon 
surrender of such Debenture, a new Debenture or Debentures in principal 
amount equal to the unredeemed portion thereof shall be issued.

   (b) If less than all the Debentures are to be redeemed, the Company shall 
give the Trustee at least 45 days' written notice in advance of the date 
fixed for redemption as to the aggregate principal amount of Debentures to be 
redeemed, and thereupon the Trustee shall select, by lot or in such other 
manner as it shall deem appropriate and fair in its discretion, the portion 
or portions (equal to $10 or any integral multiple thereof) of the Debentures 
to be redeemed and shall thereafter promptly notify the Company in writing of 
the numbers of the Debentures to be redeemed, in whole or in part. The 
Company may, if and whenever it shall so elect pursuant to the terms hereof, 
by delivery of instructions signed on its behalf by its President or any Vice 
President, instruct the Trustee or any Paying Agent to call all or any part 
of the Debentures for redemption and to give notice of redemption in the 
manner set forth in this Section 3.4, such notice to be in the name of the 
Company or its own name as the Trustee or such Paying Agent may deem 
advisable. In any case in which notice of redemption is to be given by the 
Trustee or any such Paying Agent, the Company shall deliver or cause to be 
delivered to, or permit to remain with, the Trustee or such Paying Agent, as 
the case may be, such Debenture Register, transfer books or other records, or 
suitable copies or extracts therefrom, sufficient to enable the Trustee or 
such Paying Agent to give any notice by mail that may be required under the 
provisions of this Section 3.4.

SECTION 3.5. PAYMENT UPON REDEMPTION.

   (a) If the giving of notice of redemption shall have been completed as 
above provided, the Debentures or portions of Debentures to be redeemed 
specified in such notice shall become due and payable on the date and at the 
place stated in such notice at the applicable Redemption Price, and interest 
on such Debentures or portions of Debentures shall cease to accrue on and 
after the date fixed for redemption, unless the Company shall default in the 
payment of such Redemption Price with respect to any such Debenture or 
portion thereof. On presentation and surrender of such Debentures on or after 
the date fixed for redemption at the place of payment specified in the 
notice, said Debentures shall be paid and redeemed at the Redemption Price 
(but if the date fixed for redemption is an Interest Payment Date, the 
interest installment payable on such date shall be payable to the registered 
holder at the close of business on the applicable record date pursuant to 
Section 3.3).

   (b) Upon presentation of any Debenture that is to be redeemed in part 
only, the Company shall execute and the Trustee shall authenticate and the 
office or agency where the Debenture is 

                                      18
<PAGE>

presented shall deliver to the holder thereof, at the expense of the Company, 
a new Debenture of authorized denomination in principal amount equal to the 
unredeemed portion of the Debenture so presented.

SECTION 3.6. NO SINKING FUND.

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

                                 ARTICLE IV.
                     EXTENSION OF INTEREST PAYMENT PERIOD
                                       
SECTION 4.1. EXTENSION OF INTEREST PAYMENT PERIOD.

   So long as no Event of Default has occurred and is continuing, the Company 
shall have the right, at any time and from time to time during the term of 
the Debentures, to defer payments of interest by extending the interest 
payment period of such Debentures for a period not exceeding 20 consecutive 
quarters (the "Extension Period"), during which Extension Period no interest 
shall be due and payable; provided that no Extension Period may extend beyond 
the Maturity Date. Interest, the payment of which has been deferred because 
of the extension of the interest payment period pursuant to this Section 4.1, 
shall bear interest thereon at the Coupon Rate compounded quarterly for each 
quarter of the Extension Period ("Compounded Interest"). At the end of the 
Extension Period, the Company shall calculate (and deliver such calculation 
to the Trustee) and pay all interest accrued and unpaid on the Debentures, 
including any Additional Payments and Compounded Interest (together, 
"Deferred Payments") that shall be payable to the holders of the Debentures 
in whose names the Debentures are registered in the Debenture Register on the 
first record date after the end of the Extension Period. Before the 
termination of any Extension Period, the Company may further extend such 
period, provided that such period together with all such further extensions 
thereof shall not exceed 20 consecutive quarters, or extend beyond the 
Maturity Date of the Debentures. Upon the termination of any Extension Period 
and upon the payment of all Deferred Payments then due, the Company may 
commence a new Extension Period, subject to the foregoing requirements. No 
interest shall be due and payable during an Extension Period, except at the 
end thereof, but the Company may prepay at any time all or any portion of the 
interest accrued during an Extension Period.

SECTION 4.2. NOTICE OF EXTENSION.

       (a) If the Property Trustee is the only registered holder of the 
Debentures at the time the Company selects an Extension Period, the Company 
shall give written notice to the Administrative Trustees, the Property 
Trustee and the Trustee of its selection of such Extension Period 2 Business 
Days before the earlier of (i) the next succeeding date on which 
Distributions on the Trust Securities issued by the Trust are payable; or 
(ii) the date the Trust is required to give notice of the record date, or the 
date such Distributions are payable, to the Nasdaq National Market or other 
applicable self-regulatory organization or to holders of the Preferred 
Securities issued by the Trust, but in any event at least 1 Business Day 
before such record date.


                                      19
<PAGE>

   (b) If the Property Trustee is not the only holder of the Debentures at 
the time the Company selects an Extension Period, the Company shall give the 
holders of the Debentures and the Trustee written notice of its selection of 
such Extension Period at least 2 Business Days before the earlier of (i) the 
next succeeding Interest Payment Date; or (ii) the date the Company is 
required to give notice of the record or payment date of such interest 
payment to the Nasdaq National Market or other applicable self-regulatory 
organization or to holders of the Debentures.

   (c) The quarter in which any notice is given pursuant to paragraphs (a) or 
(b) of this Section 4.2 shall be counted as one of the 20 quarters permitted 
in the maximum Extension Period permitted under Section 4.1.

SECTION 4.3. LIMITATION ON TRANSACTIONS.

   If (i) the Company shall exercise its right to defer payment of interest 
as provided in Section 4.1; or (ii) there shall have occurred any Event of 
Default, then (a) the Company shall not declare or pay any dividend on, make 
any distributions with respect to, or redeem, purchase, acquire or make a 
liquidation payment with respect to, any of its capital stock; (b) the 
Company shall not make any payment of interest, principal or premium, if any, 
or repay, repurchase or redeem any debt securities issued by the Company 
which rank pari passu with or junior to the Debentures or make any guarantee 
payments with respect to any guarantee by the Company of the debt securities 
of any subsidiary of the Company if such guarantee ranks pari passu with or 
junior in interest to the Debenture; provided, however, that notwithstanding 
the foregoing the Company may make payments pursuant to its obligations under 
the Preferred Securities Guarantee; and (c) the Company shall not redeem, 
purchase or acquire less than all of the Outstanding Debentures or any of the 
Preferred Securities.

                                  ARTICLE V.
                     PARTICULAR COVENANTS OF THE COMPANY
                                       
SECTION 5.1. PAYMENT OF PRINCIPAL AND INTEREST.

   The Company shall duly and punctually pay or cause to be paid the 
principal of and interest on the Debentures at the time and place and in the 
manner provided herein. Each such payment of the principal of and interest on 
the Debentures shall relate only to the Debentures, shall not be combined 
with any other payment of the principal of or interest on any other 
obligation of the Company, and shall be clearly and unmistakably identified 
as pertaining to the Debentures.

SECTION 5.2. MAINTENANCE OF AGENCY.

   So long as any of the Debentures remain Outstanding, the Company shall 
maintain an office or agency in the Borough of Manhattan, the City of New 
York, and at such other location or locations as may be designated as 
provided in this Section 5.2, where (i) Debentures may be presented for 
payment; (ii) Debentures may be presented as hereinabove authorized for 
registration of transfer and exchange; and (iii) notices and demands to or 
upon the Company in respect of the Debentures and this Indenture may be given 
or served, such designation to continue with respect to such office or agency 
until the Company shall, by written notice signed by its President or a Vice 
President and delivered to the Trustee, designate some other office or agency 
for such purposes or any of them. If at any time the Company shall fail to 
maintain any 

                                      20
<PAGE>

such required office or agency or shall fail to furnish the Trustee with the 
address thereof, such presentations, notices and demands may be made or 
served at the Corporate Trust Office of the Trustee, and the Company hereby 
appoints the Trustee as its agent to receive all such presentations, notices 
and demands. The Company shall give the Trustee prompt written notice of any 
such designation or rescission thereof.

SECTION 5.3. PAYING AGENTS.

   (a) The Trustee shall initially act as the Paying Agent. If the Company 
shall appoint one or more Paying Agents for the Debentures, other than the 
Trustee, the Company shall cause each such Paying Agent to execute and 
deliver to the Trustee an instrument in which such agent shall agree with the 
Trustee, subject to the provisions of this Section 5.3:

   (i) that it shall hold all sums held by it as such agent for the payment 
of the principal of or interest on the Debentures (whether such sums have 
been paid to it by the Company or by any other obligor of such Debentures) in 
trust for the benefit of the Persons entitled thereto;

   (ii) that it shall give the Trustee notice of any failure by the Company 
(or by any other obligor of such Debentures) to make any payment of the 
principal of or interest on the Debentures when the same shall be due and 
payable;

   (iii) that it shall, at any time during the continuance of any failure 
referred to in the preceding paragraph (a)(ii) above, upon the written 
request of the Trustee, forthwith pay to the Trustee all sums so held in 
trust by such Paying Agent; and

   (iv) that it shall perform all other duties of Paying Agent as set forth 
in this Indenture.

   (b) If the Company shall act as its own Paying Agent with respect to the 
Debentures, it shall on or before each due date of the principal of or 
interest on such Debentures, set aside, segregate and hold in trust for the 
benefit of the Persons entitled thereto a sum sufficient to pay such 
principal or interest so becoming due on Debentures until such sums shall be 
paid to such Persons or otherwise disposed of as herein provided and shall 
promptly notify the Trustee of such action, or any failure (by it or any 
other obligor on such Debentures) to take such action. Whenever the Company 
shall have one or more Paying Agents for the Debentures, it shall, prior to 
each due date of the principal of or interest on any Debentures, deposit with 
the Paying Agent a sum sufficient to pay the principal or interest so 
becoming due, such sum to be held in trust for the benefit of the Persons 
entitled to such principal or interest, and (unless such Paying Agent is the 
Trustee) the Company shall promptly notify the Trustee of this action or 
failure so to act.

   (c) Notwithstanding anything in this Section 5.3 to the contrary, (i) the 
agreement to hold sums in trust as provided in this Section 5.3 is subject to 
the provisions of Section 13.3 and 13.4; and (ii) the Company may at any 
time, for the purpose of obtaining the satisfaction and discharge of this 
Indenture or for any other purpose, pay, or direct any Paying Agent to pay, 
to the Trustee all sums held in trust by the Company or such Paying Agent, 
such sums to be held by the Trustee upon the same terms and conditions as 
those upon which such sums were held by the Company 

                                      21
<PAGE>

or such Paying Agent; and, upon such payment by any Paying Agent to the 
Trustee, such Paying Agent shall be released from all further liability with 
respect to such money.

SECTION 5.4. APPOINTMENT TO FILL VACANCY IN OFFICE OF THE TRUSTEE.

   The Company, whenever necessary to avoid or fill a vacancy in the office 
of Trustee, shall appoint, in the manner provided in Section 9.11, a Trustee, 
so that there shall at all times be a Trustee hereunder.

SECTION 5.5. COMPLIANCE WITH CONSOLIDATION PROVISIONS.

   The Company shall not, while any of the Debentures remain Outstanding, 
consolidate with, or merge into, or merge into itself, or sell or convey all 
or substantially all of its property to any other company unless the 
provisions of Article XII hereof are complied with.

SECTION 5.6. LIMITATION ON TRANSACTIONS.

   If Debentures are issued to the Trust or a trustee of the Trust in 
connection with the issuance of Trust Securities by the Trust and (i) there 
shall have occurred any event that would constitute an Event of Default; (ii) 
the Company shall be in default with respect to its payment of any 
obligations under the Preferred Securities Guarantee relating to the Trust; 
or (iii) if the Company shall have given notice of its election to defer 
payments of interest on such Debentures by extending the interest payment 
period as provided in this Indenture and such Extension Period, or any 
extension thereof, then (a) the Company shall not declare or pay any dividend 
on, make any distributions with respect to, or redeem, purchase, acquire or 
make a liquidation payment with respect to, any of its capital stock; (b) the 
Company shall not make any payment of principal, interest or premium, if 
any, or repay, repurchase or redeem any debt securities issued by the Company 
which rank pari passu with or junior to the Debentures; provided, however, 
that the Company may make payments pursuant to its obligations under the 
Preferred Securities Guarantee; and (c) the Company shall not redeem, 
purchase or acquire less than all of the Outstanding Debentures or any of the 
Preferred Securities.

SECTION 5.7. COVENANTS AS TO THE TRUST.

   For so long as the Trust Securities of the Trust remain outstanding, the 
Company shall (i) maintain 100% direct or indirect ownership of the Common 
Securities of the Trust; provided, however, that any permitted successor of 
the Company under this Indenture may succeed to the Company's ownership of 
the Common Securities; (ii) not voluntarily terminate, wind up or liquidate 
the Trust, except upon prior approval of the Federal Reserve if then so 
required under applicable capital guidelines or policies of the Federal 
Reserve; (iii) use its reasonable efforts to cause the Trust (a) to remain a 
business trust, except in connection with a distribution of Debentures, the 
redemption of all of the Trust Securities of the Trust or certain mergers, 
consolidations or amalgamations, each as permitted by the Trust Agreement; 
and (b) to otherwise continue not to be treated as an association taxable as 
a corporation or partnership for United States federal income tax purposes; 
and (iv) use its reasonable efforts to cause each holder of Trust Securities 
to be treated as owning an individual beneficial interest in the Debentures.

SECTION 7.1. EVENTS OF DEFAULT.

   (a) Whenever used herein with respect to the Debentures, "Event of 
Default" means any one or more of the following events that has occurred and 
is continuing:

    upon any of the Debentures, as and when the same shall become due and
    payable, and continuance of such default for a period of 30 days; provided,
    however, that a valid extension of an interest payment period by the
    Company in accordance with the terms of this Indenture shall not constitute
    a default in the payment of interest for this purpose;

         (ii) the Company defaults in the payment of the principal on the
    Debentures as and when the same shall become due and payable whether at
    maturity, upon redemption, by declaration or otherwise; provided, however,
    that a valid extension of the maturity of such Debentures in accordance
    with the terms of this Indenture shall not constitute a default in the
    payment of principal;

         (iii) the Company fails to observe or perform any other of its
    covenants or agreements with respect to the Debentures for a period of 90
    days after the date on which written notice of such failure, requiring the
    same to be remedied and stating that such notice is a "Notice of Default"
    hereunder, shall have been given to the Company by the Trustee, by
    registered or certified mail, or to the Company and the Trustee by the
    holders of at least 25% in principal amount of the Debentures at the time
    Outstanding;

         (iv) the Company pursuant to or within the meaning of any Bankruptcy
    Law (i) commences a voluntary case; (ii) consents to the entry of an order
    for relief against it in an involuntary case; (iii) consents to the
    appointment of a Custodian of it or for all or substantially all of its
    property; or (iv) makes a general assignment for the benefit of its

    of its property; or (iii) orders the liquidation of the Company, and the
    order or decree remains unstayed and in effect for 90 days; or

         (vi) the Trust shall have voluntarily or involuntarily dissolved,
    wound-up its business or otherwise terminated its existence except in
    connection with (i) the distribution of Debentures to holders of Trust
    Securities in liquidation of their interests in the Trust; (ii) the
    redemption of all of the outstanding Trust Securities of the Trust; or

   (b) In each and every such case, unless the principal of all the 
Debentures shall have already become due and payable, either the Trustee or 
the holders of not less than 25% in aggregate principal amount of the 
Debentures then Outstanding hereunder, by notice in writing to the Company 
(and to the Trustee if given by such Debentureholders) may declare the 
principal of all the Debentures to be due and payable immediately, and upon 
any such declaration the same shall become and shall be immediately due and 
payable, notwithstanding anything contained in this Indenture or in the 
Debentures.

   (c) At any time after the principal of the Debentures 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 
provided, the holders of a majority in aggregate principal amount of the 
Debentures then Outstanding hereunder, by written notice to the Company and 
the Trustee, may rescind and annul such declaration and its consequences if: 
(i) the Company has paid or deposited with the Trustee a sum sufficient to 
pay all matured installments of interest upon all the Debentures and the 
principal of any and all Debentures that shall have become due otherwise than 
by acceleration (with interest upon such principal, and upon overdue 
installments of interest, at the rate per annum expressed in the Debentures 
to the date of such payment or deposit) and the amount payable to the Trustee 
under Section 9.7; and (ii) any and all Events of Default under this 
Indenture, other than the nonpayment of principal on Debentures that shall 
not have become due by their terms, shall have been remedied or waived as 
provided in Section 7.6. No such rescission and annulment shall extend to or 
shall affect any subsequent default or impair any right consequent thereon.

   (d) In case the Trustee shall have proceeded to enforce any right with 
respect to Debentures 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 Trustee, then 
and in every such case the Company and the Trustee shall be restored 
respectively to their former positions and rights hereunder, and all rights, 
remedies and powers of the Company and the Trustee shall continue as though 
no such proceedings had been taken.

SECTION 7.2. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY THE 
TRUSTEE.

   (a) The Company covenants that (1) in case it shall default in the payment 
of any installment of interest on any of the Debentures, and such default 
shall have continued for a period of 90 Business Days; or (2) in case it 
shall default in the payment of the principal of any of the Debentures when 
the same shall have become due and payable, whether upon maturity of the 
Debentures or upon redemption or upon declaration or otherwise, then, upon 
demand of the Trustee, the Company shall pay to the Trustee, for the benefit 
of the holders of the Debentures, the whole amount that then shall have been 
become due and payable on all such Debentures for principal or interest, or 
both, as the case may be, with interest upon the overdue principal and upon 
overdue installments of interest at the rate per annum expressed in the 
Debentures; and (if the Debentures are held by the Trust or a trustee of the 
Trust, without duplication of any other amounts paid by the Trust or trustee 
in respect thereof) upon overdue installments of interest at the rate per 
annum expressed in the Debentures; and, in addition thereto, such further 
amount as 

                                      26
<PAGE>

shall be sufficient to cover the costs and expenses of collection, and the 
amount payable to the Trustee under Section 9.7.

   (b) If the Company shall fail to pay such amounts set forth in Section 
7.2(a) forthwith upon such demand, the Trustee, in its own name and as 
trustee of an express trust, shall be entitled and empowered to institute any 
action 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 Company or other obligor upon the Debentures and collect the moneys 
adjudged or decreed to be payable in the manner provided by law out of the 
property of the Company or other obligor upon the Debentures, wherever 
situated.

   (c) In case of any receivership, insolvency, liquidation, bankruptcy, 
reorganization, readjustment, arrangement, composition or judicial 
proceedings affecting the Company or the creditors or property thereof, the 
Trustee shall have power to intervene in such proceedings and take any action 
therein that may be permitted by the court and shall (except as may be 
otherwise provided by law) be entitled to file such proofs of claim and other 
papers and documents as may be necessary or advisable in order to have the 
claims of the Trustee and of the holders of the Debentures allowed for the 
entire amount due and payable by the Company under this Indenture at the date 
of institution of such proceedings and for any additional amount that may 
become due and payable by the Company after such date, and to collect and 
receive any moneys or other property payable or deliverable on any such 
claim, and to distribute the same after the deduction of the amount payable 
to the Trustee under Section 9.7; and any receiver, assignee or trustee in 
bankruptcy or reorganization is hereby authorized by each of the holders of 
the Debentures to make such payments to the Trustee, and, in the event that 
the Trustee shall consent to the making of such payments directly to such 
Debentureholders, to pay to the Trustee any amount due it under Section 9.7.

   (d) All rights of action and of asserting claims under this Indenture, or 
under any of the terms established with respect to the Debentures, may be 
enforced by the Trustee without the possession of any of such Debentures, or 
the production thereof at any trial or other proceeding relative thereto, and 
any such suit or proceeding instituted by the Trustee shall be brought in its 
own name as trustee of an express trust, and any recovery of judgment shall, 
after provision for payment to the Trustee of any amounts due under Section 
9.7, be for the ratable benefit of the holders of the Debentures. In case of 
an Event of Default hereunder, the 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 Trustee shall deem most effectual to 
protect and enforce any of such rights, either at law or in equity or 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 Trustee by this Indenture or by law. Nothing contained 
herein shall be deemed to authorize the Trustee to authorize or consent to or 
accept or adopt on behalf of any Debentureholder any plan of reorganization, 
arrangement, adjustment or composition affecting the Debentures or the rights 
of any holder thereof or to authorize the Trustee to vote in respect of the 
claim of any Debentureholder in any such proceeding.

    benefit of which such money has been collected, ratably, without preference
    or priority of any kind, according to the amounts due and payable on such
    Debentures for principal and interest, respectively.

SECTION 7.4. LIMITATION ON SUITS.

shall have any right by virtue 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 (i) such 
holder previously shall have given to the Trustee written notice of an Event 
of Default and of the continuance thereof with respect to the Debentures 
specifying such Event of Default, as hereinbefore provided; (ii) the holders 
of not less than 25% in aggregate principal amount of the Debentures then 
Outstanding shall have made written request upon the Trustee to institute 
such action, suit or proceeding in its own name as trustee hereunder; (iii) 
such holder or holders shall have offered to the Trustee such reasonable 
indemnity as it may require against the costs, expenses and liabilities to be 
incurred therein or thereby; and (iv) the 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 and during such 60 day period, 
the holders of a majority in principal amount of the Debentures do not give 
the Trustee a direction inconsistent with the request.

   (b) Notwithstanding anything contained herein to the contrary or any other 
provisions of this Indenture, the right of any holder of the Debentures to 
receive payment of the principal of and interest on the Debentures, as 
therein provided, on or after the respective due dates expressed in such 
Debenture (or in the case of redemption, on the redemption date), or to 
institute suit for the enforcement of any such payment on or after such 
respective dates or redemption date, shall not be impaired or affected 
without the consent of such holder and by accepting a Debenture hereunder it 
is expressly understood, intended and covenanted by the taker and holder of 
every Debenture with every other such taker and holder and the Trustee that 
no one or more holders of the Debentures shall have any right in any manner 
whatsoever by virtue or by availing of any provision of this Indenture to

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 the Debentures. For the protection and enforcement 
of the provisions of this Section 7.4, each and every Debentureholder and the 
Trustee shall be entitled to such relief as can be given either at law or in 
equity.

SECTION 7.5. RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER.

   (a) All powers and remedies given by this Article VII to the Trustee or to 
the Debentureholders shall, to the extent permitted by law, be deemed 
cumulative and not exclusive of any other powers and remedies available to 
the Trustee or the holders of the Debentures, 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 such Debentures.

   (b) No delay or omission of the Trustee or of any holder of any of the 
Debentures 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 7.4, every power and 
remedy given by this Article VII or by law to the Trustee or the 
Debentureholders may be exercised from time to time, and as often as shall be 
deemed expedient, by the Trustee or by the Debentureholders.

SECTION 7.6. CONTROL BY THE DEBENTUREHOLDERS.

   The holders of a majority in aggregate principal amount of the Debentures 
at the time Outstanding, determined in accordance with Section 10.4, shall 
have the right to direct the time, method and place of conducting any 
proceeding for any remedy available to the Trustee, or exercising any trust 
or power conferred on the Trustee; provided, however, that such direction 
shall not be in conflict with any rule of law or with this Indenture. Subject 
to the provisions of Section 9.1, the Trustee shall have the right to decline 
to follow any such direction if the Trustee in good faith shall, by a 
Responsible Officer or Officers of the Trustee, determine that the proceeding 
so directed would involve the Trustee in personal liability. The holders of a 
majority in aggregate principal amount of the Debentures at the time 
Outstanding affected thereby, determined in accordance with Section 10.4, may 
on behalf of the holders of all of the Debentures waive any past default in 
the performance of any of the covenants contained herein and its 
consequences, except (i) a default in the payment of the principal of or 
interest on any of the Debentures as and when the same shall become due by 
the terms of such Debentures otherwise than by acceleration (unless such 
default has been cured and a sum sufficient to pay all matured installments 
of principal and interest has been deposited with the Trustee (in accordance 
with Section 7.1(c)); (ii) a default in the covenants contained in Section 
5.6; or (iii) in respect of a covenant or provision hereof which cannot be 
modified or amended without the consent of the holder of each Outstanding 
Debenture affected; provided, however, that if the Debentures are held by the 
Trust or a trustee of the Trust, such waiver or modification to such waiver 
shall not be effective until the holders of a majority in liquidation 
preference of Trust Securities of the 

                                      29
<PAGE>

Trust shall have consented to such waiver or modification to such waiver; 
provided further, that if the Debentures are held by the Trust or a trustee 
of the Trust, and if the consent of the holder of each Outstanding Debenture 
is required, such waiver shall not be effective until each holder of the 
Trust Securities of the Trust 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 Company, the Trustee and the holders of 
the Debentures 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.

SECTION 7.7. UNDERTAKING TO PAY COSTS.

   All parties to this Indenture agree, and each holder of any Debentures by 
such holder's 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 Trustee for 
any action taken or omitted by it as the 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, 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 7.7 shall not apply 
to any suit instituted by the Trustee, to any suit instituted by any 
Debentureholder, or group of the Debentureholders holding more than 10% in 
aggregate principal amount of the Outstanding Debentures, or to any suit 
instituted by any Debentureholder for the enforcement of the payment of the 
principal of or interest on the Debentures, on or after the respective due 
dates expressed in such Debenture or established pursuant to this Indenture.

Agreement, dated ______________, 1997, by and among the Company, the Trust 
and Stifel, Nicolaus & Company, Incorporated, for itself and as 
representative of the Underwriters named therein) then, on such Option

authenticate and deliver said Debentures to or upon the written order of the

           SECTION 9.1. CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

    (a) The Trustee, prior to the occurrence of an Event of Default and 
after the curing of all Events of Default that may have occurred, shall 
undertake to perform with respect to the Debentures such duties and only such 
duties as are specifically set forth in this Indenture, and no implied 
covenants shall be read into this Indenture against the Trustee. In case an 
Event of Default has occurred that has not been cured or waived, the Trustee 
shall exercise such of the rights and powers vested in it by this Indenture, 
and use the same degree of care and skill in its exercise, as a prudent man 
would exercise or use under the circumstances in the conduct of his own 
affairs.

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

         (1) prior to the occurrence of an Event of Default and after the
     curing or waiving of all such Events of Default that may have occurred:

            (i) the duties and obligations of the Trustee shall with respect 
        to the Debentures be determined solely by the express provisions of 
        this Indenture, and the Trustee shall not be liable with respect to 
        the Debentures 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 Trustee; and

             (ii) in the absence of bad faith on the part of the Trustee, the 
        Trustee may with respect to the Debentures conclusively rely, as to 
        the truth of the statements and the correctness of the opinions 
        expressed therein, upon any certificates or opinions furnished to the 
        Trustee and conforming to the requirements of this Indenture; but in 
        the case of any such certificates or opinions that by any provision 
        hereof are specifically required to be furnished to the Trustee, the 
        Trustee shall be under a duty to examine the same to determine 
        whether or not they conform to the requirements of this Indenture;

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

         (3) the 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 holders of not less than a majority in principal amount of the
    Debentures at the time Outstanding relating to the time, method and place
    of conducting any proceeding for any remedy available to the Trustee, or


                                     31

<PAGE>

    exercising any trust or power conferred upon the Trustee under this
    Indenture with respect to the Debentures; and

         (4) none of the provisions contained in this Indenture shall require
    the 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 there is reasonable ground for
    believing 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 9.2. NOTICE OF DEFAULTS.

    Within 90 days after actual knowledge by a Responsible Officer of the 
Trustee of the occurrence of any default hereunder with respect to the 
Debentures, the Trustee shall transmit by mail to all holders of the 
Debentures, as their names and addresses appear in the Debenture Register, 
notice of such default, unless such default shall have been cured or waived; 
provided, however, that, except in the case of a default in the payment of 
the principal or interest (including any Additional Payments) on any 
Debenture, the 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 the directors and/or Responsible Officers of the Trustee 
determines in good faith that the withholding of such notice is in the 
interests of the holders of such Debentures; and provided, further, that in 
the case of any default of the character specified in section 7.1(a)(iii), no 
such notice to holders of Debentures need be sent until at least 30 days 
after the occurrence thereof. For the purposes of this Section 9.2, the term 
"default" means any event which is, or after notice or lapse of time or both, 
would become, an Event of Default with respect to the Debentures.

SECTION 9.3. CERTAIN RIGHTS OF THE TRUSTEE.

    Except as otherwise provided in Section 9.1:

   (a) The Trustee may rely and shall be protected in acting or refraining from
acting upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, approval, bond, security 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 Company mentioned herein
shall be sufficiently evidenced by a Board Resolution or an instrument signed in
the name of the Company by the President or any Vice President and by the
Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer
thereof (unless other evidence in respect thereof is specifically prescribed
herein);

   (c) The Trustee shall not be deemed to have knowledge of a default or an
Event of Default, other than an Event of Default specified in Section 7.1(a)(i)
or (ii), unless and until it receives written notification of such Event of
Default from the Company or by holders of at least 25% of the aggregate
principal amount of the Debentures at the time Outstanding (determined as
provided in Section 10.4);


                                      32

<PAGE>

   (d) The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted hereunder in
good faith and in reliance thereon;

   (e) The 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 Debentureholders, pursuant to the provisions of this Indenture, unless
such Debentureholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities that may be incurred
therein or thereby; nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of an Event of Default (that has not been
cured or waived) to exercise with respect to the Debentures 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 man would exercise or use under the
circumstances in the conduct of his own affairs;

   (f) The Trustee shall not be liable for any action taken or omitted to be
taken 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;

   (g) The 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, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Debentures
(determined as provided in Section 10.4); provided, however, that if the payment
within a reasonable time to the 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 Trustee, not reasonably assured to the Trustee by the security
afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such costs, expenses or liabilities as a condition
to so proceeding, and the reasonable expense of every such examination shall be
paid by the Company or, if paid by the Trustee, shall be repaid by the Company
upon demand; and

   (h) The Trustee may execute any of the trusts or powers hereunder or perform
any duties hereunder either directly or by or through agents or attorneys and
the Trustee shall not be responsible for any misconduct or negligence on the
part of any agent or attorney appointed with due care by it hereunder.

SECTION 9.4. THE TRUSTEE NOT RESPONSIBLE FOR RECITALS, ETC.

   (a) The Recitals contained herein and in the Debentures shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

   (b) The Trustee makes no representations as to the validity or sufficiency of
this Indenture or of the Debentures.

   (c) The Trustee shall not be accountable for the use or application by the
Company of any of the Debentures or of the proceeds of such Debentures, or for
the use or application of any 


                                      33

<PAGE>

moneys paid over by the Trustee in accordance with any provision of this 
Indenture, or for the use or application of any moneys received by any Paying 
Agent other than the Trustee.

SECTION 9.5. MAY HOLD THE DEBENTURES.

   The Trustee or any Paying Agent or Debenture Registrar for the Debentures, in
its individual or any other capacity, may become the owner or pledgee of the
Debentures with the same rights it would have if it were not Trustee, Paying
Agent or Debenture Registrar.

SECTION 9.6. MONEYS HELD IN TRUST.

   Subject to the provisions of Section 13.5, all moneys received by the Trustee
shall, until used or applied as herein provided, be held in trust for the
purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any moneys received by it hereunder except such as it
may agree with the Company to pay thereon.

SECTION 9.7. COMPENSATION AND REIMBURSEMENT.

   (a) The Company covenants and agrees to pay to the Trustee, and the Trustee
shall be entitled to, such reasonable compensation (which shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust), as the Company and the Trustee may from time to time agree in writing,
for all services rendered by it in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties hereunder of
the Trustee, and, except as otherwise expressly provided herein, the Company
shall pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the 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 Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold
it harmless against, any loss, liability or expense incurred without negligence
or bad faith on the part of the 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 in the premises.

   (b) The obligations of the Company under this Section 9.7 to compensate and
indemnify the Trustee and to pay or reimburse the 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
Debentures upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Debentures.

SECTION 9.8. RELIANCE ON OFFICERS' CERTIFICATE.

   Except as otherwise provided in Section 9.1, whenever in the administration
of the provisions of this Indenture the Trustee shall deem it necessary or
desirable that a matter be proved or established prior to taking or suffering or
omitting to take any action hereunder, such matter 


                                      34

<PAGE>

(unless other evidence in respect thereof be herein specifically prescribed) 
may, in the absence of negligence or bad faith on the part of the Trustee, be 
deemed to be conclusively proved and established by an Officers' Certificate 
delivered to the Trustee and such certificate, in the absence of negligence 
or bad faith on the part of the Trustee, shall be full warrant to the Trustee 
for any action taken, suffered or omitted to be taken by it under the 
provisions of this Indenture upon the faith thereof.

SECTION 9.9. DISQUALIFICATION; CONFLICTING INTERESTS.

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

SECTION 9.10. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

   There shall at all times be a Trustee with respect to the Debentures issued
hereunder which shall at all times be a corporation organized and doing business
under the laws of the United States 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 $50,000,000, and
subject to supervision or examination by federal, state, territorial, or
District of Columbia authority. If such corporation 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 9.10, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. The Company may not, nor may any Person
directly or indirectly controlling, controlled by, or under common control with
the Company, serve as Trustee. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 9.10, the Trustee 
shall resign immediately in the manner and with the effect specified in 
Section 9.11.

SECTION 9.11. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

   (a) The Trustee or any successor hereafter appointed, may at any time resign
by giving written notice thereof to the Company and by transmitting notice of
resignation by mail, first class postage prepaid, to the Debentureholders, as
their names and addresses appear upon the Debenture Register. Upon receiving
such notice of resignation, the Company shall promptly appoint a successor
trustee with respect to Debentures by written instrument, in duplicate, executed
by order of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no
successor trustee shall have been so appointed and have accepted appointment
within 30 days after the mailing of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor trustee with respect to Debentures, or any Debentureholder who has
been a bona fide holder of a Debenture or Debentures for at least six months
may, subject to the provisions of Section 9.10, 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.


                                      35

<PAGE>

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

         (i)  the Trustee shall fail to comply with the provisions of Section
    9.9 after written request therefor by the Company or by any Debentureholder
    who has been a bona fide holder of a Debenture or Debentures for at least
    six months; or

         (ii)  the Trustee shall cease to be eligible in accordance with the
    provisions of Section 9.10 and shall fail to resign after written request
    therefor by the Company or by any such Debentureholder; or

         (iii) the Trustee shall become incapable of acting, or shall be
    adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy
    proceeding, or a receiver of the Trustee or of its property shall be
    appointed or consented to, or any public officer shall take charge or
    control of the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation; 

then, in any such case, the Company may remove the Trustee with respect to all
Debentures and appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee,
or, subject to the provisions of Section 9.10, unless the Trustee's duty to
resign is stayed as provided herein, any Debentureholder who has been a bona
fide holder of a Debenture or Debentures for at least six months may, on behalf
of that holder and all others similarly situated, petition any court of
competent jurisdiction for the removal of the 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 Trustee and appoint a successor trustee.

   (c) The holders of a majority in aggregate principal amount of the Debentures
at the time Outstanding may at any time remove the Trustee by so notifying the
Trustee and the Company and may appoint a successor Trustee with the consent of
the Company.

   (d) Any resignation or removal of the Trustee and appointment of a successor
trustee with respect to the Debentures pursuant to any of the provisions of this
Section 9.11 shall become effective upon acceptance of appointment by the
successor trustee as provided in Section 9.12.

SECTION 9.12. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

   (a) In case of the appointment hereunder of a successor trustee with respect
to the Debentures, every successor trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, 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, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
trustee all the rights, powers, and trusts of the retiring Trustee and shall
duly assign, transfer and deliver to such successor trustee all property and
money held by such retiring Trustee hereunder.


                                      36

<PAGE>

   (b) Upon request of any successor trustee, the Company shall execute any and
all instruments for more fully and certainly vesting in and confirming to such
successor trustee all such rights, powers and trusts referred to in paragraph
(a) of this Section 9.12.

   (c) No successor trustee shall accept its appointment unless at the time of
such acceptance such successor trustee shall be qualified and eligible under
this Article IX.

   (d) Upon acceptance of appointment by a successor trustee as provided in this
Section 9.12, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Debentureholders,
as their names and addresses appear upon the Debenture Register. If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

SECTION 9.13. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

   Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
qualified under the provisions of Section 9.9 and eligible under the provisions
of Section 9.10, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. In case any Debentures shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and
deliver the Debentures so authenticated with the same effect as if such
successor Trustee had itself authenticated such Debentures.

SECTION 9.14. PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

   The 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 Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.

                                      ARTICLE X.

                           CONCERNING THE DEBENTUREHOLDERS

SECTION 10.1. EVIDENCE OF ACTION BY THE HOLDERS.

   (a) Whenever in this Indenture it is provided that the holders of a majority
or specified percentage in aggregate principal amount of the Debentures 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 majority 


                                      37

<PAGE>

or specified percentage have joined therein may be evidenced by any 
instrument or any number of instruments of similar tenor executed by such 
holders of Debentures in Person or by agent or proxy appointed in writing.

   (b) If the Company shall solicit from the Debentureholders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Company may, at its option, as evidenced by an Officers' Certificate, fix in
advance a record date for the determination of Debentureholders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other
action, but the Company 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 Debentureholders of record at the close of business on the record date shall
be deemed to be Debentureholders for the purposes of determining whether
Debentureholders of the requisite proportion of Outstanding Debentures have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other action, and for that purpose the
Outstanding Debentures shall be computed as of the record date; provided,
however, that no such authorization, agreement or consent by such
Debentureholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than 6
months after the record date.

SECTION 10.2. PROOF OF EXECUTION BY THE DEBENTUREHOLDERS.

   Subject to the provisions of Section 9.1, proof of the execution of any
instrument by a Debentureholder (such proof shall not require notarization) or
such Debentureholder's agent or proxy and proof of the holding by any Person of
any of the Debentures shall be sufficient if made in the following manner:

   (a) The fact and date of the execution by any such Person of any instrument
may be proved in any reasonable manner acceptable to the Trustee.

   (b) The ownership of Debentures shall be proved by the Debenture Register of
such Debentures or by a certificate of the Debenture Registrar thereof.

   (c) The Trustee may require such additional proof of any matter referred to
in this Section 10.2 as it shall deem necessary.

SECTION 10.3. WHO MAY BE DEEMED OWNERS.

   Prior to the due presentment for registration of transfer of any Debenture,
the Company, the Trustee, any Paying Agent, any Authenticating Agent and any
Debenture Registrar may deem and treat the Person in whose name such Debenture
shall be registered upon the books of the Company as the absolute owner of such
Debenture (whether or not such Debenture shall be overdue and notwithstanding
any notice of ownership or writing thereon made by anyone other than the
Debenture Registrar) for the purpose of receiving payment of or on account of
the principal of and interest on such Debenture (subject to Section 2.3) and for
all other purposes;


                                      38

<PAGE>

and neither the Company nor the Trustee nor any Paying Agent nor any 
Authenticating Agent nor any Debenture Registrar shall be affected by any 
notice to the contrary.

SECTION 10.4. CERTAIN DEBENTURES OWNED BY COMPANY DISREGARDED.

   In determining whether the holders of the requisite aggregate principal
amount of the Debentures have concurred in any direction, consent or waiver
under this Indenture, the Debentures that are owned by the Company or any other
obligor on the Debentures or by any Person directly or indirectly controlling or
controlled by or under common control with the Company or any other obligor on
the Debentures shall be disregarded and deemed not to be Outstanding for the
purpose of any such determination, except that (i) for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, consent or waiver, only Debentures that the Trustee actually knows
are so owned shall be so disregarded; and (ii) for purposes of this Section
10.4, the Trust shall be deemed not to be controlled by the Company. The
Debentures so owned that have been pledged in good faith may be regarded as
Outstanding for the purposes of this Section 10.4, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right so to act with
respect to such Debentures and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor. In case of a dispute as to
such right, any decision by the Trustee taken upon the advice of counsel shall
be full protection to the Trustee.

SECTION 10.5. ACTIONS BINDING ON THE FUTURE DEBENTUREHOLDERS.

   At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 10.1, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Debentures specified
in this Indenture in connection with such action, any holder of a Debenture that
is shown by the evidence to be included in the Debentures the holders of which
have consented to such action may, by filing written notice with the Trustee,
and upon proof of holding as provided in Section 10.2, revoke such action so far
as concerns such Debenture. Except as aforesaid any such action taken by the
holder of any Debenture shall be conclusive and binding upon such holder and
upon all future holders and owners of such Debenture, and of any Debenture
issued in exchange therefor, on registration of transfer thereof or in place
thereof, irrespective of whether or not any notation in regard thereto is made
upon such Debenture. Any action taken by the holders of the majority or
percentage in aggregate principal amount of the Debentures specified in this
Indenture in connection with such action shall be conclusively binding upon the
Company, the Trustee and the holders of all the Debentures.

                                     ARTICLE XI.
                               SUPPLEMENTAL INDENTURES

SECTION 11.1. SUPPLEMENTAL INDENTURES WITHOUT THE CONSENT OF THE
DEBENTUREHOLDERS.

   In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or 


                                      39

<PAGE>

indentures supplemental hereto (which shall conform to the provisions of the 
Trust Indenture Act as then in effect), without the consent of the 
Debentureholders, for one or more of the following purposes:

   (a) to cure any ambiguity, defect, or inconsistency herein, or in the
Debentures;

   (b) to provide for uncertificated Debentures in addition to or in place of
certificated Debentures;

   (c) to add to the covenants of the Company for the benefit of the holders of
all or any of the Debentures or to surrender any right or power herein conferred
upon the Company;

   (d) to make any change that does not adversely affect the rights of any
Debentureholder in any material respect;

   (e) to qualify or maintain the qualification of this Indenture under the
Trust Indenture Act; or 

   (f) to evidence a consolidation or merger involving the Company as permitted
under Section 12.1.

   The Trustee is hereby authorized to join with the Company in the execution of
any such supplemental indenture, and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
Any supplemental indenture authorized by the provisions of this Section 11.1 may
be executed by the Company and the Trustee without the consent of the holders of
any of the Debentures at the time Outstanding, notwithstanding any of the
provisions of Section 11.2.

SECTION 11.2. SUPPLEMENTAL INDENTURES WITH CONSENT OF THE DEBENTUREHOLDERS.

   With the consent (evidenced as provided in Section 10.1) of the holders of
not less than a majority in aggregate principal amount of the Debentures at the
time Outstanding, the Company, when authorized by Board Resolutions, and the
Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto (which shall conform to the provisions of the
Trust Indenture Act as then in effect) for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or of modifying in any manner not
covered by Section 11.1 the rights of the holders of the Debentures under this
Indenture; provided, however, that no such supplemental indenture shall without
the consent of the holders of each Debenture then Outstanding and affected
thereby, (i) extend the fixed maturity of any Debentures, reduce the principal
amount thereof, or reduce the rate or extend the time of payment of interest
thereon; or (ii) reduce the aforesaid percentage of Debentures, the holders of
which are required to consent to any such supplemental 


                                      40

<PAGE>

indenture; provided further, that if the Debentures are held by the Trust or 
a trustee of the Trust, such supplemental indenture shall not be effective 
until the holders of a majority in liquidation preference of Trust Securities 
of the Trust shall have consented to such supplemental indenture; provided 
further, that if the Debentures are held by the Trust or a trustee of the 
Trust and if the consent of the holder of each Outstanding Debenture is 
required, such supplemental indenture shall not be effective until each 
holder of the Trust Securities of the Trust shall have consented to such 
supplemental indenture. It shall not be necessary for the consent of the 
Debentureholders affected thereby under this Section 11.2 to approve the 
particular form of any proposed supplemental indenture, but it shall be 
sufficient if such consent shall approve the substance thereof.

SECTION 11.3. EFFECT OF SUPPLEMENTAL INDENTURES.

   Upon the execution of any supplemental indenture pursuant to the provisions
of this Article XI, 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 Trustee,
the Company and the holders of Debentures 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.

SECTION 11.4. THE DEBENTURES AFFECTED BY SUPPLEMENTAL INDENTURES.

   The Debentures affected by a supplemental indenture, authenticated and
delivered after the execution of such supplemental indenture pursuant to the
provisions of this Article XI, may bear a notation in form approved by the
Company, provided such form meets the requirements of any exchange upon which
the Debentures may be listed, as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Debentures so modified as to
conform, in the opinion of the Board of Directors of the Company, to any
modification of this Indenture contained in any such supplemental indenture may
be prepared by the Company, authenticated by the Trustee and delivered in

SECTION 11.5. EXECUTION OF SUPPLEMENTAL INDENTURES.

   (a) Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of the Debentureholders
required to consent thereto as aforesaid, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion but
shall not be obligated to enter into such supplemental indenture. The Trustee,
subject to the provisions of Sections 9.1, may receive an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant to this
Article XI is authorized or permitted by, and conforms to, the terms of this
Article XI and that it is proper for the Trustee under the provisions of this
Article XI to join in the execution thereof.

   (b) Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section 11.5, the
Trustee shall transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental 


                                      41

<PAGE>

indenture, to the Debentureholders as their names and addresses appear upon 
the Debenture Register. Any failure of the 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.

SECTION 12.1. THE COMPANY MAY CONSOLIDATE, ETC.

   Nothing contained in this Indenture or in any of the Debentures shall prevent
any consolidation or merger of the Company with or into any other corporation or
corporations (whether or not affiliated with the Company, as the case may be),
or successive consolidations or mergers in which the Company, as the case may
be, or its successor or successors shall be a party or parties, or shall prevent
any sale, conveyance, transfer or other disposition of the property of the
Company, as the case may be, or its successor or successors as an entirety, or
substantially as an entirety, to any other corporation (whether or not
affiliated with the Company, as the case may be, or its successor or successors)
authorized to acquire and operate the same; provided, however, that the Company
hereby covenants and agrees that (i) upon any such consolidation, merger, sale,
conveyance, transfer or other disposition, the due and punctual payment, in the
case of the Company, of the principal of and interest on all of the Debentures,
according to their tenor and the due and punctual performance and observance of
all the covenants and conditions of this Indenture to be kept or performed by
the Company as the case may be, shall be expressly assumed, by supplemental
indenture (which shall conform to the provisions of the Trust Indenture Act, as
then in effect) satisfactory in form to the Trustee executed and delivered to
the Trustee by the entity formed by such consolidation, or into which the
Company, as the case may be, shall have been merged, or by the entity which
shall have acquired such property; (ii) in case the Company consolidates with or
merges into another Person or conveys or transfers its properties and assets
substantially as an entirety to any Person, the successor Person is organized
under the laws of the United States or any state or the District of Columbia;
and (iii) immediately after giving effect thereto, an Event of Default, and no
event which, after notice or lapse of time or both, would become an Event of
Default, shall have occurred and be continuing.

SECTION 12.2. SUCCESSOR CORPORATION SUBSTITUTED.

   (a) In case of any such consolidation, merger, sale, conveyance, transfer or
other disposition and upon the assumption by the successor corporation, by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of the due and punctual payment of the principal of and
interest on all of the Debentures Outstanding and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Company, such successor corporation shall succeed to and be
substituted for the Company, with the same effect as if it had been named as the
Company herein and thereupon the predecessor corporation shall be relieved of
all obligations and covenants under this Indenture and the Debentures.


                                      42

<PAGE>

   (b) In case of any such consolidation, merger, sale, conveyance, transfer or
other disposition such changes in phraseology and form (but not in substance)
may be made in the Debentures thereafter to be issued as may be appropriate.

   (c) Nothing contained in this Indenture or in any of the Debentures shall
prevent the Company from merging into itself or acquiring by purchase or
otherwise, all or any part of, the property of any other Person (whether or not
affiliated with the Company).

SECTION 12.3. EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE.

   The Trustee, subject to the provisions of Section 9.1, may receive an Opinion
of Counsel as conclusive evidence that any such consolidation, merger, sale,

the provisions of this Article XII.

   If at any time: (a) the Company shall have delivered to the Trustee for

or paid as provided in Section 2.9) and all Debentures for whose payment money
or Governmental Obligations have theretofore been deposited in trust or
segregated and held in trust by the Company (and thereupon repaid to the Company
or discharged from such trust, as provided in Section 13.5); or (b) all such
Debentures not theretofore delivered to the 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 redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and the
Company shall deposit or cause to be deposited with the Trustee as trust funds
the entire amount in moneys or Governmental Obligations sufficient, or a
combination thereof sufficient, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay at maturity or upon redemption all Debentures
not theretofore delivered to the Trustee for cancellation, including principal
and interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company; then this Indenture shall
thereupon cease to be of further effect except for the provisions of Sections

maturity or redemption date, as the case may be, and Sections 9.6 and 13.5, that

                                      43

<PAGE>

Company by depositing irrevocably with the Trustee as trust funds moneys or 
an amount of Governmental Obligations sufficient in the opinion of a 
nationally recognized certified public accounting firm to pay at maturity or 
upon redemption all Debentures not theretofore delivered to the Trustee for 
cancellation, including principal and interest due or to become due to such 
date of maturity or date fixed for redemption, as the case may be, and if the 
Company shall also pay or cause to be paid all other sums payable hereunder 
by the Company, then after the date such moneys or Governmental Obligations, 
as the case may be, are deposited with the Trustee, the obligations of the 
Company under this Indenture shall cease to be of further effect except for 
the provisions of Sections 2.3, 2.7, 2.9, 5.1, 5.2, 5.3, 9.6, 9.7, 9.10 and 
13.5 hereof that shall survive until such Debentures shall mature and be

acting as its own Paying Agent), to the holders of the Debentures for the
payment or redemption of which such moneys or Governmental Obligations have been
deposited with the Trustee.

SECTION 13.4. PAYMENT OF MONIES HELD BY PAYING AGENTS.

   In connection with the satisfaction and discharge of this Indenture, all

Trustee and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

SECTION 13.5. REPAYMENT TO THE COMPANY.

   Any monies or Governmental Obligations deposited with any Paying Agent or the
Trustee, or then held by the Company in trust, for payment of principal of or
interest on the Debentures that are not applied but remain unclaimed by the
holders of such Debentures for at least two years after the date upon which the
principal of or interest on such Debentures shall have respectively become due
and payable, shall be repaid to the Company, as the case may be, on May 31 of
each year or (if then held by the Company) shall be discharged from such trust;
and thereupon the Paying Agent and the Trustee shall be released from all
further liability with respect to such moneys or Governmental Obligations, and
the holder of any of the Debentures entitled to receive such payment shall
thereafter, as an unsecured general creditor, look only to the Company for the
payment thereof.

period after such nominal date.

SECTION 15.9. CONFLICT WITH TRUST INDENTURE ACT.

   If and to the extent that any provision of this Indenture limits, qualifies
or conflicts with the duties imposed by Sections 310 to 317, inclusive, of the
Trust Indenture Act, such imposed duties shall control.

SECTION 15.10. COUNTERPARTS.

   This Indenture may be executed in any number of counterparts, each of which
shall be an original, but such counterparts shall together constitute but one
and the same instrument.

SECTION 15.11. SEPARABILITY.

   In case any one or more of the provisions contained in this Indenture or in
the Debentures 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 Debentures,
but this Indenture and the Debentures shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.

SECTION 15.12. ASSIGNMENT.

   This Indenture is binding upon and inures to the benefit of the parties
thereto and their respective successors and assigns. This Indenture may not

SECTION 15.13. ACKNOWLEDGMENT OF RIGHTS; RIGHT OF SETOFF.

   (a) The Company acknowledges that, with respect to any Debentures held by the
Trust or a trustee of the Trust, if the Property Trustee fails to enforce its
rights under this Indenture as the holder of the Debentures held as the assets
of the Trust, any holder of Preferred Securities may institute legal proceedings
directly against the Company 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,
and notwithstanding the provisions of Section 7.4(a) hereof, if an Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay principal or interest on the Debentures on the
date such principal or interest is otherwise payable (or in the case of
redemption, on the 


                                      47

<PAGE>

redemption date), the Company acknowledges that a holder of Preferred 
Securities may directly institute a proceeding for enforcement of payment to 
such holder of the principal of or interest on the Debentures having a 
principal amount equal to the aggregate liquidation amount of the Preferred 
Securities of such holder on or after the respective due date specified in 
the Debentures.

   (b) Notwithstanding anything to the contrary contained in this Indenture, the
Company shall have the right to setoff any payment it is otherwise required to
make hereunder in respect of any Trust Securities to the extent that the Company
has previously made, or is concurrently making, a payment to the holder of such
Trust Securities under the Preferred Securities Guarantee or in connection with
a proceeding for enforcement of payment of the principal of or interest on the
Debentures directly brought by holders of any Trust Securities.

   (c) For so long as any of the Preferred Securities remain outstanding, if,
upon an Event of Default, the Property Trustee fails or the holders of not less
than 25% in principal amount of the Outstanding Debentures fail to declare the
principal of all of the Debentures to be immediately due and payable, the
holders of at least 25% in liquidation amount of the Preferred Securities then
outstanding shall have the right to make such declaration by a notice in writing
to the Depositor and the Property Trustee; and upon any such declaration such
principal amount of and the accrued interest on all of the Debentures shall
become immediately due and payable, provided that the payment of principal and
interest on such Debentures shall remain subordinated to the extent provided in
this Indenture.

                                     ARTICLE XVI.
                           SUBORDINATION OF THE DEBENTURES

SECTION 16.1. AGREEMENT TO SUBORDINATE.

   The Company covenants and agrees, and each holder of the Debentures issued
hereunder by such holder's acceptance thereof likewise covenants and agrees,
that all the Debentures shall be issued subject to the provisions of this
Article XVI; and each holder of a Debenture, whether upon original issue or upon
transfer or assignment thereof, accepts and agrees to be bound by such
provisions. The payment by the Company of the principal of and interest on all
the Debentures issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all Senior Debt, Subordinated Debt and Additional
Senior Obligations of the Company (collectively, "Senior Indebtedness") to the
extent provided herein, whether outstanding at the date of this Indenture or
thereafter incurred. No provision of this Article XVI shall prevent the
occurrence of any default or Event of Default hereunder.

SECTION 16.2. DEFAULT ON SENIOR DEBT, SUBORDINATED DEBT OR ADDITIONAL SENIOR
OBLIGATIONS.

   In the event and during the continuation of any default by the Company in the
payment of principal, premium, interest or any other payment due on any Senior
Indebtedness, or in the event that the maturity of any Senior Indebtedness has
been accelerated because of a default, then, in either case, no payment shall be
made by the Company with respect to the principal 


                                      48

<PAGE>

(including redemption payments) of or interest on the Debentures. In the 
event that, notwithstanding the foregoing, any payment shall be received by 
the Trustee when such payment is prohibited by the preceding sentence of this 
Section 16.2, such payment shall be held in trust for the benefit of, and 
shall be paid over or delivered 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 that 
the holders of the Senior Indebtedness (or their representative or 
representatives or a trustee) notify the Trustee in writing within 90 days of 
such payment of the amounts then due and owing on the Senior Indebtedness and 
only the amounts specified in such notice to the Trustee shall be paid to the 
holders of the Senior Indebtedness.

SECTION 16.3. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

   (a) Upon any payment by the Company or distribution of assets of the 
Company of any kind or character, whether in cash, property or securities, to 
creditors upon any dissolution or winding-up or liquidation or reorganization 
of the Company, whether voluntary or involuntary or in bankruptcy, 
insolvency, receivership or other proceedings, all amounts due upon all 
Senior Indebtedness shall first be paid in full, or payment thereof provided 
for in money in accordance with its terms, before any payment is made by the 
Company on account of the principal or interest on the Debentures; and upon 
any such dissolution or winding-up or liquidation or reorganization, any 
payment by the Company, or distribution of assets of the Company of any kind 
or character, whether in cash, property or securities, to which the holders 
of the Debentures or the Trustee would be entitled to receive from the 
Company, except for the provisions of this Article XVI, shall be paid by the 
Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent 
or other Person making such payment or distribution, or by the holders of the 
Debentures or by the Trustee under this Indenture if received by them or it, 
directly to the holders of Senior Indebtedness (pro rata to such holders on 
the basis of the respective amounts of Senior Indebtedness held by such 
holders, as calculated by the Company) 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 such Senior Indebtedness in full, in money or money's 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 
holders of the Debentures or to the Trustee.

   (b) In the event that, notwithstanding the foregoing, any payment or 
distribution of assets of the Company of any kind or character, whether in 
cash, property or securities, prohibited by the foregoing, shall be received 
by the Trustee before 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 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 Company, for application to the payment of all Senior 
Indebtedness, as the case may be, remaining unpaid to the extent necessary to 
pay such Senior Indebtedness in full in money in 

                                      49
<PAGE>

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.

   (c) For purposes of this Article XVI, the words "cash, property or 
securities" shall not be deemed to include shares of stock of the Company as 
reorganized or readjusted, or securities of the Company 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 XVI with respect to the Debentures to the payment of all Senior 
Indebtedness, as the case may be, 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 Company with, or the merger of the Company into, another 
corporation or the liquidation or dissolution of the Company following the 
conveyance or transfer of its property as an entirety, or substantially as an 
entirety, to another corporation upon the terms and conditions provided for 
in Article XII shall not be deemed a dissolution, winding-up, liquidation or 
reorganization for the purposes of this Section 16.3 if such other 
corporation shall, as a part of such consolidation, merger, conveyance or 
transfer, comply with the conditions stated in Article XII. Nothing in 
Section 16.2 or in this Section 16.3 shall apply to claims of, or payments 
to, the Trustee under or pursuant to Section 9.7.

SECTION 16.4. SUBROGATION.

   (a) Subject to the payment in full of all Senior Indebtedness, the rights 
of the holders of the Debentures 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 Company, as the case may be, applicable 
to such Senior Indebtedness until the principal of and interest on the 
Debentures 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 holders of the Debentures or 
the Trustee would be entitled except for the provisions of this Article XVI, 
and no payment over pursuant to the provisions of this Article XVI to or for 
the benefit of the holders of such Senior Indebtedness by holders of the 
Debentures or the Trustee, shall, as between the Company, its creditors other 
than holders of Senior Indebtedness of the Company, and the holders of the 
Debentures, be deemed to be a payment by the Company to or on account of such 
Senior Indebtedness. It is understood that the provisions of this Article XVI 
are and are intended solely for the purposes of defining the relative rights 
of the holders of the Debentures, on the one hand, and the holders of such 
Senior Indebtedness on the other hand.

   (b) Nothing contained in this Article XVI or elsewhere in this Indenture 
or in the Debentures is intended to or shall impair, as between the Company, 
its creditors (other than the holders of Senior Indebtedness), and the 
holders of the Debentures, the obligation of the Company, which is absolute 
and unconditional, to pay to the holders of the Debentures the principal of 
and interest on the Debentures 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 Debentures and creditors of the 
Company, as the case may be, other than the holders of Senior Indebtedness, 
as 

                                      50
<PAGE>

the case may be, nor shall anything herein or therein prevent the Trustee or 
the holder of any Debenture from exercising all remedies otherwise permitted 
by applicable law upon default under this Indenture, subject to the rights, 
if any, under this Article XVI of the holders of such Senior Indebtedness in 
respect of cash, property or securities of the Company, as the case may be, 
received upon the exercise of any such remedy.

   (c) Upon any payment or distribution of assets of the Company referred to 
in this Article XVI, the Trustee, subject to the provisions of Article IX, 
and the holders of the Debentures shall be entitled to conclusively rely upon 
any order or decree made by any court of competent jurisdiction in which such 
dissolution, winding-up, liquidation or reorganization proceedings are 
pending, or a certificate of the receiver, trustee in bankruptcy, liquidation 
trustee, agent or other Person making such payment or distribution, delivered 
to the Trustee or to the holders of the Debentures, for the purposes of 
ascertaining the Persons entitled to participate in such distribution, the 
holders of Senior Indebtedness and other indebtedness of the Company, as the 
case may be, the amount thereof or payable thereon, the amount or amounts 
paid or distributed thereon and all other facts pertinent thereto or to this 
Article XVI.

SECTION 16.5. THE TRUSTEE TO EFFECTUATE SUBORDINATION.

   Each holder of Debentures by such holder's acceptance thereof authorizes 
and directs the Trustee on such holder's behalf to take such action as may be 
necessary or appropriate to effectuate the subordination provided in this 
Article XVI and appoints the Trustee such holder's attorney-in-fact for any 
and all such purposes.

SECTION 16.6. NOTICE BY THE COMPANY.

   (a) The Company shall give prompt written notice to a Responsible Officer 
of the Trustee of any fact known to the Company that would prohibit the 
making of any payment of monies to or by the Trustee in respect of the 
Debentures pursuant to the provisions of this Article XVI. Notwithstanding 
the provisions of this Article XVI or any other provision of this Indenture, 
the Trustee shall not be charged with knowledge of the existence of any facts 
that would prohibit the making of any payment of monies to or by the Trustee 
in respect of the Debentures pursuant to the provisions of this Article XVI, 
unless and until a Responsible Officer of the Trustee shall have received 
written notice thereof from the Company or a holder or holders of Senior 
Indebtedness or from any trustee therefor; and before the receipt of any such 
written notice, the Trustee, subject to the provisions of Section 9.1, shall 
be entitled in all respects to assume that no such facts exist; provided, 
however, that if the Trustee shall not have received the notice provided for 
in this Section 16.6 at least 2 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 interest on any 
Debenture), then, anything herein contained to the contrary notwithstanding, 
the 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 2 
Business Days prior to such date.

   (b) The Trustee, subject to the provisions of Section 9.1, shall be 
entitled to conclusively rely on the delivery to it of a written notice by a 
Person representing himself to be a holder of Senior 

                                      51
<PAGE>

Indebtedness (or a trustee on behalf of such holder) 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 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 XVI, the 
Trustee may request such Person to furnish evidence to the reasonable 
satisfaction of the 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 XVI, and, if such evidence is not furnished, 
the Trustee may defer any payment to such Person pending judicial 
determination as to the right of such Person to receive such payment.

SECTION 16.7. RIGHTS OF THE TRUSTEE; HOLDERS OF THE SENIOR INDEBTEDNESS.

   (a) The Trustee in its individual capacity shall be entitled to all the 
rights set forth in this Article XVI in respect of any Senior Indebtedness at 
any time held by it, to the same extent as any other holder of Senior 
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any 
of its rights as such holder. The Trustee's right to compensation and 
reimbursement of expenses as set forth in Section 9.7 shall not be subject to 
the subordination provisions of the Article XVI.

   (b) With respect to the holders of the Senior Indebtedness, the Trustee 
undertakes to perform or to observe only such of its covenants and 
obligations as are specifically set forth in this Article XVI, and no implied 
covenants or obligations with respect to the holders of such Senior 
Indebtedness shall be read into this Indenture against the Trustee. The 
Trustee shall not be deemed to owe any fiduciary duty to the holders of such 
Senior Indebtedness and, subject to the provisions of Section 9.1, the 
Trustee shall not be liable to any holder of such Senior Indebtedness if it 
shall pay over or deliver to holders of Debentures, the Company or any other 
Person money or assets to which any holder of such Senior Indebtedness shall 
be entitled by virtue of this Article XVI or otherwise.

SECTION 16.8. SUBORDINATION MAY NOT BE IMPAIRED.

   (a) No right of any present or future holder of any Senior Indebtedness 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 
Company or by any act or failure to act, in good faith, by any such holder, 
or by any noncompliance by the Company 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.

   (b) Without in any way limiting the generality of Section 16.8(a), the 
holders of Senior Indebtedness may, at any time and from time to time, 
without the consent of or notice to the Trustee or the holders of the 
Debentures, without incurring responsibility to the holders of the Debentures 
and without impairing or releasing the subordination provided in this Article 
XVI or the obligations hereunder of the holders of the Debentures to the 
holders of such Senior Indebtedness, do any one or more of the following: (i) 
change the manner, place or terms of 

                                      52
<PAGE>

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 Company and any other Person.

   IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be 
duly executed, and their respective corporate seals to be hereunto affixed 
and attested, all as of the day and year first above written.

                         ____% SUBORDINATED DEBENTURE

                             DUE DECEMBER 30, 2027

         Indiana United Bancorp, an Indiana corporation (the "Company," which 
term includes any successor corporation under the Indenture hereinafter 
referred to), for value received, hereby promises to pay to State Street Bank 
and Trust Company as Property Trustee for IUB Capital Trust, or registered 
assigns, the principal sum of ____________________________ Dollars 
($__________) on December 30, 2027 (the "Stated Maturity"), and to pay 
interest on said principal sum from ____________, 1997, 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, quarterly (subject to 
deferral as set forth herein) in arrears on March 31, June 30, September 30 
and December 31 of each year commencing December 31, 1997, at the rate of 
____% per annum until the principal hereof shall have become due and payable, 
and on any overdue principal and (without duplication) on any overdue 
installment of interest at the same rate per annum compounded quarterly. The 
amount of interest payable on any Interest Payment Date shall be computed on 
the basis of a 360-day year of twelve 30-day months.  The amount of interest 
for any partial period shall be computed on the basis of the number of days 
elapsed in a 360-day year of twelve 30-day months.  In the event that any 
date on which interest is payable on this Debenture is not a business day, 
then payment of interest payable on such date shall be made on the next 
succeeding day that is a Business Day (as defined in the Indenture) (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. The interest installment so 
payable, and punctually paid or duly provided for, on any Interest Payment 
Date shall, as provided in the Indenture, be paid to the person in whose name 
this Debenture (or one or more Predecessor Debentures, as defined in said 
Indenture) is registered at the close of business on the regular record date 
for such interest installment, which shall be the close of business on the 
fifteenth day of the last month of the calendar quarter in which the Interest 
Payment Date occurs unless otherwise provided in the Indenture. The principal 
of and the interest on this Debenture shall be payable at the office or 
agency of the 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 Company by check mailed to the 
registered holder at such address as shall appear in the Debenture Register. 
Notwithstanding the foregoing, so long as the holder of this Debenture is the 
Property Trustee, the payment of the principal of 

                                      A-1
<PAGE>

and interest on this Debenture shall be made at such place and to such 
account as may be designated by the Trustee.

         This Debenture may be redeemed at any time by the Company on any 
date not earlier than December 30, 2002, subject to the Company having 
received prior approval of the Federal Reserve if then required under 
applicable capital guidelines or policies of the Federal Reserve. Such date 
may also be extended at any time at the election of the Company for one or 
more periods, but in no event to a date later than December 30, 2036, subject 
to certain limitations described in the Indenture.

         The indebtedness evidenced by this Debenture 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 (as defined in the 
Indenture). This Debenture is issued subject to the provisions of the 
Indenture with respect thereto. Each holder of this Debenture, by accepting 
the same, (a) agrees to and shall be bound by such provisions; (b) authorizes 
and directs the 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 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 Debenture shall not be entitled to any benefit under the 
Indenture hereinafter referred to, be valid or become obligatory for any 
purpose until the Certificate of Authentication hereon shall have been signed 
by or on behalf of the Trustee.

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

                         ____% SUBORDINATED DEBENTURE

                                  (CONTINUED)

         This Debenture is one of the subordinated debentures of the Company 
(herein sometimes referred to as the "Debentures"), all issued or to be 
issued under and pursuant to an Indenture dated as of ___________, 1997 (the 
"Indenture") duly executed and delivered between the Company and State Street 
Bank and Trust Company, as Trustee (the "Trustee"), to which Indenture 
reference is hereby made for a description of the rights, limitations of 
rights, obligations, duties and immunities thereunder of the Trustee, the 
Company and the holders of the Debentures. The Debentures are limited in 
aggregate principal amount as specified in the Indenture.

         The Company shall have the right to redeem this Debenture at the 
option of the Company, without premium or penalty, in whole or in part at any 
time on or after December 30, 2002 (an "Optional Redemption"), or at any time 
in certain circumstances upon the occurrence of a Special Event (as defined 
in the Indenture), at a redemption price (the "Redemption Price") equal to 
100% of the principal amount hereof plus any accrued but unpaid interest 
hereon, to the date of such redemption, plus Additional Payments, if any. Any 
redemption pursuant to this paragraph shall be made upon not less than 30 
days nor more than 60 days notice, at the Redemption Price. If the Debentures 
are only partially redeemed by the Company pursuant to an Optional 
Redemption, the Debentures shall be redeemed pro rata or by lot or by any 
other method utilized by the Trustee as described in the Indenture.  In the 
event of an Optional Redemption of this Debenture in part only, a new 
Debenture or Debentures for the unredeemed portion hereof shall be issued in 
the name of the holder hereof upon the cancellation hereof.

         In case an Event of Default (as defined in the Indenture) shall have 
occurred and be continuing, the principal of all of the Debentures 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 Company and the 
Trustee, with the consent of the holders of not less than a majority in 
aggregate principal amount of the Debentures 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 any supplemental indenture or of 
modifying in any manner the rights of the holders of the Debentures; 
provided, however, that no such supplemental indenture shall without the 
consent of the holders of each Debenture then Outstanding and affected 
thereby, (i) extend the fixed maturity of the Debentures, reduce the 
principal amount thereof, or reduce the rate or extend the time of payment of 
interest thereon; or (ii) reduce the aforesaid percentage of the Debentures, 
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 Debentures at the time 
Outstanding, on behalf of all of the holders of the Debentures, to waive any 
past default in the performance of any of the 

                                      A-5
<PAGE>

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 interest on any of the Debentures. Any such consent or waiver 
by the registered holder of this Debenture (unless revoked as provided in the 
Indenture) shall be conclusive and binding upon such holder and upon all 
future holders and owners of this Debenture and of any Debenture 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 Debenture.

         No reference herein to the Indenture and no provision of this 
Debenture or of the Indenture shall alter or impair the obligation of the 
Company, which is absolute and unconditional, to pay the principal and 
interest on this Debenture at the time and place and at the rate and in the 
money herein prescribed.

         The Company, as further described in the Indenture, shall have the 
right at any time during the term of the Debentures and from time to time to 
defer payments of interest by extending the interest payment period of such 
Debentures for up to 20 consecutive quarters (each, an "Extension Period"), 
at the end of which period the Company shall calculate (and deliver such 
calculation to the Trustee) and pay all interest then accrued and unpaid on 
the Debentures, including any Additional Payments and Compounded Interest (as 
defined in the Indenture and together, the "Deferred Payments") that shall be 
payable to the holders of the Debentures in whose names the Debentures are 
registered in the Debenture Register on the first record date after the end 
of the Extension Period. Before the termination of any such Extension Period, 
the Company may further extend such Extension Period, provided that such 
Extension Period together with all such further extensions thereof shall not 
exceed 20 consecutive quarters. At the termination of any such Extension 
Period and upon the payment of all Deferred Payments then due, the Company 
may commence a new Extension Period.

         As provided in the Indenture and subject to certain limitations 
therein set forth, this Debenture is transferable by the registered holder 
hereof on the Debenture Register (as defined in the Indenture) of the 
Company, upon surrender of this Debenture for registration of transfer at the 
office or agency of the Trustee accompanied by a written instrument or 
instruments of transfer in form satisfactory to the Company or the Trustee 
duly executed by the registered holder hereof or his attorney duly authorized 
in writing, and thereupon one or more new Debentures of authorized 
denominations and for the same aggregate principal amount shall be issued to 
the designated transferee or transferees. No service charge shall be made for 
any such transfer, but the Company 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 
Debenture, the Company, the Trustee, any Paying Agent (as defined in the 
Indenture) and the Debenture Registrar may deem and treat the registered 
holder hereof as the absolute owner hereof (whether or not this Debenture 
shall be overdue and notwithstanding any notice of ownership or writing 
hereon made by anyone other than the Debenture Registrar) for the purpose of 
receiving payment of or on account of the principal hereof and interest due 
hereon and for all other purposes, and 

                                      A-6
<PAGE>

neither the Company nor the Trustee nor any Paying Agent nor any Debenture 
Registrar shall be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the 
interest on this Debenture, or for any claim based hereon, or otherwise in 
respect hereof, or based on or in respect of the Indenture, against any 
incorporator, stockholder, officer or director, past, present or future, as 
such, of the Company or of any predecessor or successor corporation, 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.

         The Debentures are issuable only in registered form without coupons

<PAGE>

Redemptions of the Trust Securities shall be made and the Redemption Price

has immediately available funds then on hand and available in the Payment 
Account for the payment of such Redemption Price.

   (d) If the Property Trustee gives a notice of redemption in respect of any

deposit with the Paying Agent funds sufficient to pay the applicable 
Redemption Price and shall give the Paying Agent irrevocable instructions and

Distributions payable on or prior to the Redemption Date for any Trust 
Securities called for redemption shall be payable to the Holders of such 
Trust Securities as they appear on the Securities Register for the Trust 
Securities on the relevant record dates for the related Distribution Dates. 
If notice of redemption shall have been given and funds deposited as 
required, then upon the date of such deposit, all rights of Securityholders 
holding Trust Securities so called for redemption shall cease, except the 
right of such Securityholders to receive the Redemption Price and any 
Distribution payable on or prior to the Redemption Date, but without 
interest, and such Trust Securities shall cease to be Outstanding. In the 
event that any date on which any Redemption Price is payable is not a 
Business Day, then payment of the Redemption Price payable on such date shall 
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) with the same force

Depositor pursuant to the Guarantee, Distributions on such Trust Securities 
shall continue to accumulate, at the then applicable rate, from the

payment date shall be the date fixed for redemption for purposes of 
calculating the Redemption Price.

   (e) Payment of the Redemption Price on the Trust Securities shall be made

Securities are to be redeemed on a Redemption Date, then the aggregate 
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a 
pro rata basis (based on Liquidation Amounts) among the Common Securities and 
the Preferred Securities. The particular Preferred Securities to be redeemed 
shall be selected not more than 60 days prior to the Redemption Date by the 
Property Trustee from the Outstanding Preferred Securities not previously 
called for redemption, by such method (including, without limitation, by lot) 
as the Property Trustee shall deem fair and appropriate and which may provide 
for the selection for redemption of portions (equal to the Liquidation Amount 
or an integral multiple of such Liquidation Amount in excess thereof) of the 
Liquidation Amount of the Preferred Securities of a denomination larger than 
such Liquidation Amount.  The Property Trustee shall promptly notify the 
Securities Registrar in writing of the Preferred Securities selected for 
redemption and, in the case of any Preferred Securities selected for partial

of this 

                                       17
<PAGE>

Trust Agreement, unless the context otherwise requires, all provisions 
relating to the redemption of the Preferred Securities shall relate, in the 
case of any Preferred Securities redeemed or to be redeemed only in part, to 
the portion of the Liquidation Amount of the Preferred Securities which has 
been or is to be redeemed.

   SECTION 403.  SUBORDINATION OF THE COMMON SECURITIES.

   (a) Payment of Distributions (including Additional Amounts, if applicable) 
on, and the Redemption Price of, the Trust Securities, as applicable, shall 
be made, subject to Section 402(f), pro rata among the Common Securities and 
the Preferred Securities based on the Liquidation Amount of the Trust 
Securities; provided, however, that if on any Distribution Date or Redemption 
Date any Event of Default resulting from a Debenture Event of Default shall 
have occurred and be continuing, no payment of any Distribution (including 
Additional Amounts, if applicable) on, or Redemption Price of, any Common 
Security, and no other payment on account of the redemption, liquidation or 
other acquisition of the Common Securities, shall be made unless payment in 
full in cash of all accumulated and unpaid Distributions (including 
Additional Amounts, if applicable) on all Outstanding Preferred Securities 
for all Distribution periods terminating on or prior thereto, or in the case 
of payment of the Redemption Price the full amount of such Redemption Price 
on all Outstanding Preferred Securities then called for redemption, shall 
have been made or provided for, and all funds immediately available to the 
Property Trustee shall first be applied to the payment in full in cash of all 
Distributions (including Additional Amounts, if applicable) on, or the 
Redemption Price of, the Preferred Securities then due and payable.

   (b) In the case of the occurrence of any Event of Default resulting from a 
Debenture Event of Default, the Holder of the Common Securities shall be 
deemed to have waived any right to act with respect to any such Event of 
Default under this Trust Agreement until the effect of all such Events of 
Default with respect to the Preferred Securities shall have been cured, 
waived or otherwise eliminated. Until any such Event of Default under this 
Trust Agreement with respect to the Preferred Securities shall have been so 
cured, waived or otherwise eliminated, the Property Trustee shall act solely 
on behalf of the Holders of the Preferred Securities and not the Holder of 
the Common Securities, and only the Holders of the Preferred Securities shall 
have the right to direct the Property Trustee to act on their behalf.

   SECTION 404.  PAYMENT PROCEDURES.

   Payments of Distributions (including Additional Amounts, if applicable) in 
respect of the Preferred Securities shall be made by check mailed to the 
address of the Person entitled thereto as such address shall appear on the 
Securities Register. Payments in respect of the Common Securities shall be 
made in such manner as shall be mutually agreed between the Property Trustee 
and the Common Securityholder.

   SECTION 405.  TAX RETURNS AND REPORTS.

   The Administrative Trustees shall prepare (or cause to be prepared), at 
the Depositor's expense, and file all United States federal, state and local 
tax and information returns and reports 

                                       18
<PAGE>

required to be filed by or in respect of the Trust. In this regard, the 
Administrative Trustees shall (a) prepare and file (or cause to be prepared 
and filed) the appropriate Internal Revenue Service form required to be filed 
in respect of the Trust in each taxable year of the Trust; and (b) prepare 
and furnish (or cause to be prepared and furnished) to each Securityholder 
the appropriate Internal Revenue Service form required to be furnished to 
such Securityholder or the information required to be provided on such form. 
The Administrative Trustees shall provide the Depositor with a copy of all 
such returns and reports promptly after such filing or furnishing. The 
Property Trustee shall comply with United States federal withholding and 
backup withholding tax laws and information reporting requirements with 
respect to any payments to the Securityholders under the Trust Securities.

   SECTION 406.  PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.

   Upon receipt under the Debentures of Additional Payments, the Property 
Trustee, at the direction of an Administrative Trustee or the Depositor, 
shall promptly pay any taxes, duties or governmental charges of whatsoever 
nature (other than withholding taxes) imposed on the Trust by the United 
States or any other taxing authority.

   SECTION 407.  PAYMENTS UNDER THE INDENTURE.

   Any amount payable hereunder to any Holder of Preferred Securities shall 
be reduced by the amount of any corresponding payment such Holder has 
directly received under the Indenture pursuant to Section 514(b) or (c) 
hereof.

   SECTION 501.  INITIAL OWNERSHIP.

   Upon the creation of the Trust and the contribution by the Depositor 
pursuant to Section 203 and until the issuance of the Trust Securities, and 
at any time during which no Trust Securities are outstanding, the Depositor 
shall be the sole beneficial owner of the Trust.

   SECTION 502.  THE TRUST SECURITIES CERTIFICATES.

   The Preferred Securities Certificates shall be issued in minimum 
denominations of the Liquidation Amount and integral multiples of such 
Liquidation Amount in excess thereof, and the Common Securities Certificates 
shall be issued in denominations of the Liquidation Amount and integral 
multiples thereof. The Trust Securities Certificates shall be executed on 
behalf of the Trust by manual or facsimile signature of at least one 
Administrative Trustee.  The Trust Securities Certificates bearing the manual 
or facsimile signatures of individuals who were, at the time when such 
signatures shall have been affixed, authorized to sign on behalf of the 
Trust, shall be validly issued and entitled to the benefits of this Trust 
Agreement, notwithstanding that such individuals or any of them shall have 
ceased to be so authorized prior to the delivery of such Trust Securities 
Certificates or did not hold such offices at the date of delivery of such 
Trust Securities Certificates. A transferee of a Trust Securities Certificate 
shall become a 

                                       19
<PAGE>

Securityholder, and shall be entitled to the rights and subject to the 
obligations of a Securityholder hereunder, upon due registration of such 
Trust Securities Certificate in such transferee's name pursuant to Sections 
504 and 511.

   SECTION 503.  EXECUTION, AUTHENTICATION AND DELIVERY OF THE TRUST 
SECURITIES CERTIFICATES.

   (a) On the Closing Date and on the date on which the Underwriter exercises 
the Option, as applicable, the Administrative Trustees shall cause the Trust 
Securities Certificates, in an aggregate Liquidation Amount as provided in 
Sections 204 and 205, to be executed on behalf of the Trust by the manual or 
facsimile signature of at least one of the Administrative Trustees and 
delivered to or upon the written order of the Depositor, signed by its Chief 
Executive Officer, President, any Vice President, the Treasurer or any 
Assistant Treasurer without further corporate action by the Depositor, in 
authorized denominations.

   (b) A Preferred Securities Certificate 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 
Preferred Securities Certificate has been authenticated under this Trust 
Agreement.  Each Preferred Security Certificate shall be dated the date of 
its authentication.

   (c) Upon the written order of the Trust signed by an Administrative 
Trustee, the Property Trustee shall authenticate and make available for 
delivery the Preferred Securities Certificates.

   (d) The Property Trustee may appoint an Authenticating Agent acceptable to 
the Trust to authenticate the Preferred Securities.  An Authenticating Agent 
may authenticate the Preferred Securities whenever the Property Trustee may 
do so. Each reference in this Trust Agreement to authentication by the 
Property Trustee includes authentication by such agent.  An Authenticating 
Agent has the same rights as the Property Trustee to deal with the Depositor 
or the Trust.

   SECTION 504.  REGISTRATION OF TRANSFER AND EXCHANGE OF THE PREFERRED 
SECURITIES CERTIFICATES.

   (a) The Depositor shall keep or cause to be kept, at the office or agency 
maintained pursuant to Section 508, a register or registers for the purpose 
of registering the Trust Securities Certificates and transfers and exchanges 
of the Preferred Securities Certificates (herein referred to as the 
"Securities Register") in which the registrar designated by the Depositor 
(the "Securities Registrar"), subject to such reasonable regulations as it 
may prescribe, shall provide for the registration of the Preferred Securities 
Certificates and the Common Securities Certificates (subject to Section 510 
in the case of the Common Securities Certificates) and registration of 
transfers and exchanges of the Preferred Securities Certificates as herein 
provided. The Property Trustee shall be the initial Securities Registrar.

   (b) Upon surrender for registration of transfer of any Preferred 
Securities Certificate at the office or agency maintained pursuant to Section 
508, the Administrative Trustees or any one of them shall execute and 
deliver, in the name of the designated transferee or transferees, one or more 
new Preferred Securities Certificates in authorized denominations of a like 
aggregate 

                                       20
<PAGE>

Liquidation Amount dated the date of execution by the manual or facsimile 
signature of such Administrative Trustee or Trustees. The Securities 
Registrar shall not be required to register the transfer of any of the 
Preferred Securities that have been called for redemption. At the option of a 
Holder, the Preferred Securities Certificates may be exchanged for other 
Preferred Securities Certificates in authorized denominations of the same 
class and of a like aggregate Liquidation Amount upon surrender of the 
Preferred Securities Certificates to be exchanged at the office or agency 
maintained pursuant to Section 508.

   (c) Every Preferred Securities Certificate presented or surrendered for 
registration of transfer or exchange shall be accompanied by a written 
instrument of transfer in form satisfactory to the Property Trustee and the 
Securities Registrar duly executed by the Holder or his attorney duly 
authorized in writing. Each Preferred Securities Certificate surrendered for 
registration of transfer or exchange shall be canceled and subsequently 
disposed of by the Property Trustee in accordance with its customary 
practice. The Trust shall not be required to (i) issue, register the transfer 
of, or exchange any of the Preferred Securities during a period beginning at 
the opening of business 15 calendar days before the date of mailing of a 
notice of redemption of any of the Preferred Securities called for redemption 
and ending at the close of business on the day of such mailing; or (ii) 
register the transfer of or exchange any of the Preferred Securities so 
selected for redemption, in whole or in part, except the unredeemed portion 
of any such Preferred Securities being redeemed in part.

   (d) No service charge shall be made for any registration of transfer or 
exchange of Preferred Securities Certificates, but the Securities Registrar 
may require payment of a sum sufficient to cover any tax or governmental 
charge that may be imposed in connection with any transfer or exchange of the 
Preferred Securities Certificates.

   SECTION 505.  MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES 
CERTIFICATES.

   If (a) any mutilated Trust Securities Certificate shall be surrendered to 
the Securities Registrar, or if the Securities Registrar shall receive 
evidence to its satisfaction of the destruction, loss or theft of any Trust 
Securities Certificate; and (b) there shall be delivered to the Securities 
Registrar, the Property Trustee and the Administrative Trustees such security 
or indemnity as may be required by them to save each of them harmless, then 
in the absence of notice that such Trust Securities Certificate shall have 
been acquired by a bona fide purchaser, the Administrative Trustees, or any 
one of them, on behalf of the Trust shall execute and make available for 
delivery, in exchange for or in lieu of any such mutilated, destroyed, lost 
or stolen Trust Securities Certificate, a new Trust Securities Certificate of 
like class, tenor and denomination. In connection with the issuance of any 
new Trust Securities Certificate under this Section 505, the Administrative 
Trustees or the Securities Registrar may require the payment of a sum 
sufficient to cover any tax or other governmental charge that may be imposed 
in connection therewith. Any duplicate Trust Securities Certificate issued 
pursuant to this Section 505 shall constitute conclusive evidence of an 
undivided beneficial interest in the assets of the Trust, as if originally 
issued, whether or not the lost, stolen or destroyed Trust Securities 
Certificate shall be found at any time.

                                       21
<PAGE>

   SECTION 506.  PERSONS DEEMED THE SECURITYHOLDERS.

   The Trustees, the Paying Agent and the Securities Registrar shall treat 
the Person in whose name any Trust Securities Certificate shall be registered 
in the Securities Register as the owner of such Trust Securities Certificate 
for the purpose of receiving Distributions and for all other purposes 
whatsoever, and neither the Trustees nor the Securities Registrar shall be 
bound by any notice to the contrary.

   SECTION 507.  ACCESS TO LIST OF THE SECURITYHOLDERS' NAMES AND ADDRESSES.

   At any time when the Property Trustee is not also acting as the Securities 
Registrar, the Administrative Trustees or the Depositor shall furnish or 
cause to be furnished to the Property Trustee (a) semi-annually on or before 
January 15 and July 15 in each year, a list, in such form as the Property 
Trustee may reasonably require, of the names and addresses of the 
Securityholders as of the most recent record date; and (b) promptly after 
receipt by any Administrative Trustee or the Depositor of a request therefor 
from the Property Trustee in order to enable the Property Trustee to 
discharge its obligations under this Trust Agreement, in each case to the 
extent such information is in the possession or control of the Administrative 
Trustees or the Depositor and is not identical to a previously supplied list 
or has not otherwise been received by the Property Trustee in its capacity as 
Securities Registrar. The rights of the Securityholders to communicate with 
other Securityholders with respect to their rights under this Trust Agreement 
or under the Trust Securities, and the corresponding rights of the Trustee 
shall be as provided in the Trust Indenture Act. Each Holder, by receiving 
and holding a Trust Securities Certificate, and each owner shall be deemed to 
have agreed not to hold the Depositor, the Property Trustee or the 
Administrative Trustees accountable by reason of the disclosure of its name 
and address, regardless of the source from which such information was derived.

   SECTION 508.  MAINTENANCE OF OFFICE OR AGENCY.

   The Administrative Trustees shall maintain in a location or locations 
designated by the Administrative Trustees, an office or offices or agency or 
agencies where the Preferred Securities Certificates may be surrendered for 
registration of transfer or exchange and where notices and demands to or upon 
the Trustees in respect of the Trust Securities Certificates may be served. 
The Administrative Trustees initially designate the Corporate Trust Office of 
the Property Trustee, Two International Place, 4th Floor, Boston, 
Massachusetts 02110, as the principal corporate trust office for such 
purposes. The Administrative Trustees shall give prompt written notice to the 
Depositor and to the Securityholders of any change in the location of the 
Securities Register or any such office or agency.

   SECTION 509.  APPOINTMENT OF THE PAYING AGENT.

   The Paying Agent shall initially be the Property Trustee, and any 
co-paying agent chosen by the Property Trustee must be acceptable to the 
Administrative Trustees and the Depositor. The Paying Agent shall make 
Distributions to the Securityholders from the Payment Account and shall 
report the amounts of such Distributions to the Property Trustee and the 
Administrative 

                                       22
<PAGE>

Trustees. Any Paying Agent shall have the revocable power to withdraw funds 
from the Payment Account for the purpose of making the Distributions referred 
to above. The Administrative Trustees may revoke such power and remove the 
Paying Agent if such Trustees determine in their sole discretion that the 
Paying Agent shall have failed to perform its obligations under this Trust 
Agreement in any material respect. Any Person acting as Paying Agent shall be 
permitted to resign as Paying Agent upon 30 days' written notice to the 
Administrative Trustees, the Property Trustee and the Depositor. In the event 
that the Property Trustee shall no longer be the Paying Agent or a successor 
Paying Agent shall resign or its authority to act be revoked, the 
Administrative Trustees shall appoint a successor that is acceptable to the 
Property Trustee and the Depositor to act as the Paying Agent (which shall be 
a bank or trust company). The Administrative Trustees shall cause such 
successor Paying Agent or any additional Paying Agent appointed by the 
Administrative Trustees to execute and deliver to the Trustees an instrument 
in which such successor Paying Agent or additional Paying Agent shall agree 
with the Trustees that as Paying Agent, such successor Paying Agent or 
additional Paying Agent shall hold all sums, if any, held by it for payment 
to the Securityholders in trust for the benefit of the Securityholders 
entitled thereto until such sums shall be paid to such Securityholders. The 
Paying Agent shall return all unclaimed funds to the Property Trustee and, 
upon removal of a Paying Agent, such Paying Agent shall also return all funds 
in its possession to the Property Trustee. The provisions of Sections 801, 
803 and 806 shall apply to the Property Trustee also in its role as the 
Paying Agent, for so long as the Property Trustee shall act as Paying Agent 
and, to the extent applicable, to any other Paying Agent appointed hereunder. 
Any reference in this Trust Agreement to the Paying Agent shall include any 
co-paying agent unless the context requires otherwise.

   SECTION 510.  OWNERSHIP OF THE COMMON SECURITIES BY THE DEPOSITOR.

   On the Closing Date, the Depositor shall acquire and retain beneficial and 
record ownership of the Common Securities. To the fullest extent permitted by 
law, any attempted transfer of the Common Securities (other than a transfer 
in connection with a merger or consolidation of the Depositor into another 
corporation pursuant to Section 12.1 of the Indenture) shall be void. The 
Administrative Trustees shall cause each Common Securities Certificate issued 
to the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT 
TRANSFERABLE".

   SECTION 511.  THE PREFERRED SECURITIES CERTIFICATES.

   (a) Each owner shall receive a Preferred Securities Certificate 
representing such owner's interest in such Preferred Securities. Upon the 
issuance of the Preferred Securities Certificates, the Trustees shall 
recognize the record holders of the Preferred Securities Certificates as the 
Securityholders. The Preferred Securities Certificates shall be printed, 
lithographed or engraved or may be produced in any other manner as is 
reasonably acceptable to the Administrative Trustees, as evidenced by the 
execution thereof by the Administrative Trustees or any one of them.

   (b) A single Common Securities Certificate representing the Common 
Securities shall be issued to the Depositor in the form of a definitive 
Common Securities Certificate.

<PAGE>

   SECTION 513.  [Intentionally Omitted]

   SECTION 514.  RIGHTS OF THE SECURITYHOLDERS.

   (a)   The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 209, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights. When issued and delivered to Holders
of the Preferred Securities against payment of the purchase price therefor, the
Preferred Securities shall be fully paid and nonassessable interests in the
Trust. The Holders of the Preferred Securities, in their capacities as such,
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.

   (b)   For so long as any of the Preferred Securities remain Outstanding, if,
upon a Debenture Event of Default, the Debenture Trustee fails or the holders of
not less than 25% in principal amount of the outstanding Debentures fail to
declare the principal of all of the Debentures to be immediately due and
payable, the Holders of at least 25% in Liquidation Amount of the Preferred
Securities then Outstanding shall have such right by a notice in writing to the
Depositor and the Debenture Trustee; and upon any such declaration such
principal amount of and the accrued interest on all of the Debentures shall
become immediately due and payable, provided that the payment of principal and
interest on such Debentures shall remain subordinated to the extent provided in
the Indenture.

   (c)   For so long as any of the Preferred Securities remain Outstanding,
upon a Debenture Event of Default arising from the failure to pay interest or
principal on the Debentures, the Holders of any of the Preferred Securities then
Outstanding shall, to the fullest extent permitted by law, have the right to
directly institute proceedings for enforcement of payment to such Holders of
principal of or interest on the Debentures having a principal amount equal to
the Liquidation Amount of the Preferred Securities of such Holders.

   SECTION 601.  LIMITATIONS ON VOTING RIGHTS.

   (a)   Except as provided in this Section 601, in Sections 514, 810 and 1002
and in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto; nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.


                                      24

<PAGE>

   (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 the Debenture Trustee with respect to such
Debentures; (ii) waive any past default which is waivable under Article VII of
the Indenture; (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable; 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 at least a majority in Liquidation Amount of all the
Outstanding Preferred Securities; provided, however, that where a consent under
the Indenture would require the consent of each holder of outstanding Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior written consent of each Holder of the Preferred Securities. The
Trustees shall not revoke any action previously authorized or approved by a vote
of the Holders of the Outstanding Preferred Securities, except when authorized
by a subsequent vote of the Holders of the Outstanding Preferred Securities. The
Property Trustee shall notify each Holder of the Outstanding Preferred
Securities of any notice of default received from the Debenture Trustee with
respect to the Debentures. In addition to obtaining the foregoing approvals of
the Holders of the Preferred Securities, prior to taking any of the foregoing
actions, the Trustees shall, at the expense of the Depositor, obtain an Opinion
of Counsel experienced in such matters to the effect that the Trust shall
continue to be classified as a grantor trust and not as an association taxable
as a corporation for United States federal income tax purposes on account of
such action.

   (c)   If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise; or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
the Outstanding Preferred Securities as a class shall be entitled to vote on
such amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities. No amendment to this Trust
Agreement may be made if, as a result of such amendment, the Trust would cease
to be classified as a grantor trust or would be classified as an association
taxable as a corporation for United States federal income tax purposes.

   SECTION 602.  NOTICE OF MEETINGS.

   Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 1008 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.


                                      25

<PAGE>

   SECTION 603.  MEETINGS OF THE PREFERRED SECURITYHOLDERS.

   (a)  No annual meeting of the Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of the Securityholders to
vote on any matter in respect of which the Preferred Securityholders are
entitled to vote upon the written request of the Preferred Securityholders of
25% of the Outstanding Preferred Securities (based upon their aggregate
Liquidation Amount) and the Administrative Trustees or the Property Trustee may,
at any time in their discretion, call a meeting of the Preferred Securityholders
to vote on any matters as to which the Preferred Securityholders are entitled to
vote.

   (b)  The Preferred Securityholders of record of 50% of the Outstanding
Preferred Securities (based upon their aggregate Liquidation Amount), present in
person or by proxy, shall constitute a quorum at any meeting of the
Securityholders.

   (c)  If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their aggregate
Liquidation Amount) held by the Preferred Securityholders of record present,
either in person or by proxy, at such meeting shall constitute the action of the
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

   SECTION 604.  VOTING RIGHTS.

   The Securityholders shall be entitled to one vote for each dollar value of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote (and such dollar
value shall be $10 per Preferred Security until such time, if any, as the
Liquidation Amount is changed as provided herein).

   SECTION 605.  PROXIES, ETC.

   At any meeting of the Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy, shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
When Trust Securities are held jointly by several persons, any one of them may
vote at any meeting in person or by proxy in respect of such Trust Securities,
but if more than one of them shall be present at such meeting in person or by
proxy, and such joint owners or their proxies so present disagree as to any vote
to be cast, such vote shall not be received in respect of such Trust Securities.
A proxy purporting to be executed by or on behalf of a Securityholder shall be
deemed valid unless challenged at or prior to its exercise, and, the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

   SECTION 606.  SECURITYHOLDER ACTION BY WRITTEN CONSENT.

   Any action which may be taken by the Securityholders at a meeting may be
taken without a meeting if the Securityholders holding more than a majority of
all of the Outstanding Trust 


                                      26

<PAGE>


Securities (based upon their aggregate Liquidation Amount) entitled to vote 
in respect of such action (or such larger proportion thereof as shall be 
required by any express provision of this Trust Agreement) shall consent to 
the action in writing.

   SECTION 607.  RECORD DATE FOR VOTING AND OTHER PURPOSES.

   For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any Distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative Trustees may from time to time fix a date, not
more than 90 days prior to the date of any meeting of the Securityholders or the
payment of Distribution or other action, as the case may be, as a record date
for the determination of the identity of the Securityholders of record for such
purposes.

   SECTION 608.  ACTS OF THE SECURITYHOLDERS.

   (a)  Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by the Securityholders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Securityholders in
person or by an agent duly appointed in writing; and, except as otherwise
expressly provided herein, such action shall become effective when such
instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 801) conclusive in favor
of the Trustees, if made in the manner provided in this Section 608.

   (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which any Trustee receiving the same deems sufficient.

   (c)  The ownership of the Preferred Securities shall be proved by the
Securities Register.

   (d)  Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

                                  ARTICLE VIII
                                    TRUSTEES

   SECTION 801.  CERTAIN DUTIES AND RESPONSIBILITIES.

   (a)  The duties and responsibilities of the Trustees shall be as provided
by this Trust Agreement and, in the case of the Property Trustee, by the Trust
Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. No Administrative Trustee nor the Delaware Trustee shall be liable for its
act or omissions hereunder except as a result of its own gross negligence or
willful misconduct. The Property Trustee's liability shall be determined under
the Trust Indenture Act. Whether or not therein expressly so provided, every
provision of this Trust Agreement relating to the conduct or affecting the
liability of or affording protection to the Trustees shall be subject to the
provisions of this Section 801. To the extent that, at law or in equity, the
Delaware Trustee or an Administrative Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or to the Securityholders,
the Delaware Trustee or such Administrative Trustee shall not be liable to the
Trust or to any Securityholder for such Trustee's good faith reliance on the
provisions of this Trust Agreement. The provisions of this Trust Agreement, to
the extent that they restrict the duties and liabilities of the Delaware Trustee
or the Administrative Trustees otherwise existing at law or in equity, are
agreed by the Depositor and the Securityholders to replace such other duties and
liabilities of the Delaware Trustee and the Administrative Trustees, as the case
may be.

   (b)  All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a Paying
Agent to make payments in accordance with the terms hereof. With respect to the
relationship of each Securityholder and the Trustee, each Securityholder, by its
acceptance of a Trust Security, agrees that it shall look solely to the revenue
and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that the Trustees are not personally
liable to it for any amount distributable in respect of any Trust Security or
for any other liability in respect of any Trust Security. This Section 801(b)
does not limit the liability of the Trustees expressly set forth elsewhere in
this Trust Agreement or, in the case of the Property Trustee, in the Trust
Indenture Act.

   (c)  No provision of this Trust Agreement 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)  the Property Trustee shall not be liable for any error of judgment
made in good faith by an authorized officer of the Property Trustee, unless it
shall be proved that the Property Trustee was negligent in ascertaining the
pertinent facts;


                                      31

<PAGE>

    (ii)  the Property 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 Holders of not less than a majority in Liquidation Amount of
the Trust Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or exercising any
trust or power conferred upon the Property Trustee under this Trust Agreement;

    (iii) the Property Trustee's sole duty with respect to the custody,
safe keeping and physical preservation of the Debentures and the Payment Account
shall be to deal with such property in a similar manner as the Property Trustee
deals with similar property for its own account, subject to the protections and
limitations on liability afforded to the Property Trustee under this Trust
Agreement and the Trust Indenture Act;

    (iv)  the Property Trustee shall not be liable for any interest on any money
received by it except as it may otherwise agree with the Depositor and money
held by the Property Trustee need not be segregated from other funds held by it
except in relation to the Payment Account maintained by the Property Trustee
pursuant to Section 301 and except to the extent otherwise required by law; and

    (v)   the Property Trustee shall not be responsible for monitoring the
compliance by the Administrative Trustees or the Depositor with their respective
duties under this Trust Agreement, nor shall the Property Trustee be liable for
the negligence, default or misconduct of the Administrative Trustees or the
Depositor.

   SECTION 802.  CERTAIN NOTICES.

   (a)  Within 5 Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 1008, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. For purposes of
this Section 802, the term "Event of Default" means any event that is, or after
notice or lapse of time or both would become, an Event of Default.

   (b)  The Administrative Trustees shall transmit, to the Securityholders in
the manner and to the extent provided in Section 1008, notice of the Depositor's
election to begin or further extend an Extension Period on the Debentures
(unless such election shall have been revoked), and of any election by the
Depositor to extend or accelerate the Maturity Date of the Debentures within the
time specified for transmitting such notice to the holders of the Debentures
pursuant to the Indenture as originally executed.

   SECTION 803.  CERTAIN RIGHTS OF THE PROPERTY TRUSTEE.

   Subject to the provisions of Section 801:

   (a)  the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, 


                                      32

<PAGE>

opinion, report, notice, request, consent, order, appraisal, bond, debenture, 
note, other evidence of indebtedness 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)  if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action; or
(ii) in construing any of the provisions of this Trust Agreement, the Property
Trustee finds the same ambiguous or inconsistent with other provisions contained
herein; or (iii) the Property Trustee is unsure of the application of any
provision of this Trust Agreement, then, except as to any matter as to which the
Preferred Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within 10
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than 2 Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Securityholders, in
which event the Property Trustee shall have no liability except for its own bad
faith, negligence or willful misconduct;

   (c)  any direction or act of the Depositor or the Administrative Trustees
contemplated by this Trust Agreement shall be sufficiently evidenced by an
Officers' Certificate;

   (d)  whenever in the administration of this Trust Agreement, the Property
Trustee shall deem it desirable that a matter be established before undertaking,
suffering or omitting any action hereunder, the Property Trustee (unless other
evidence is herein specifically prescribed) may, in the absence of bad faith on
its part, request and conclusively rely upon an Officers' Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

   (e)  the Property Trustee shall have no duty to see to any recording,
filing or registration of any instrument (including any financing or
continuation statement, any filing under tax or securities laws or any filing
under tax or securities laws) or any rerecording, refiling or reregistration
thereof;

   (f)  the Property Trustee may consult with counsel of its choice (which
counsel may be counsel to the Depositor or any of its Affiliates) and the advice
of such counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon and, in accordance with such advice, such counsel may be
counsel to the Depositor or any of its Affiliates, and may include any of its
employees; the Property Trustee shall have the right at any time to seek
instructions concerning the administration of this Trust Agreement from any
court of competent jurisdiction;

   (g)  the Property Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Trust Agreement at the request, order
or direction of any of the 


                                      33

<PAGE>


Securityholders, pursuant to this Trust Agreement, unless such 
Securityholders shall have offered to the Property Trustee reasonable 
security or indemnity against the costs, expenses and liabilities that may be 
incurred therein or thereby; nothing contained herein shall, however, relieve 
the Property Trustee of the obligation, upon the occurrence of an Event of 
Default (that has not been cured or waived) to exercise with respect to the 
Debentures, such of the rights and powers vested in it by this Trust 
Agreement, and to use the same degree of care and skill in their exercise as 
a prudent man would exercise or use under the circumstances in the conduct of 
his own affairs;

   (h)  the Property 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, note or other evidence of indebtedness or other paper or document,
unless requested in writing to do so by the Holders of not less than a majority
in Liquidation Amount of the Securities, but the Property Trustee may make such
further inquiry or investigation into such facts or matters as it may see fit;

   (i)  the Property Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through its agents or
attorneys, provided that the Property Trustee shall be responsible for its own
negligence or recklessness with respect to selection of any agent or attorney
appointed by it hereunder;

   (j)  whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Securities
which instructions may only be given by the Holders of the same proportion in
Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action; (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received; and (iii) shall
be protected in acting in accordance with such instructions; and

   (k)  except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement. No provision of this
Trust Agreement 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.

   SECTION 804.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

   The Recitals contained herein and in the Trust Securities Certificates shall
be taken as the statements of the Trust, and the Trustees do not assume any
responsibility for their correctness. The Trustees shall not be accountable for
the use or application by the Depositor of the proceeds of the Debentures.


                                      34

<PAGE>

   SECTION 805.  MAY HOLD SECURITIES.

   Any Trustee or any other agent of any Trustee or the Trust, in its individual
or any other capacity, may become the owner or pledgee of the Trust Securities
and, subject to Sections 808 and 813 and except as provided in the definition of
the term "Outstanding" in Article I, may otherwise deal with the Trust with the
same rights it would have if it were not a Trustee or such other agent.

   SECTION 806.  COMPENSATION; INDEMNITY; FEES.

   The Depositor agrees:

   (a)  to pay to the Trustees from time to time reasonable compensation for
all services rendered by them hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust);

   (b)  except as otherwise expressly provided herein, to reimburse the
Trustees upon request for all reasonable expenses, disbursements and advances
incurred or made by the Trustees in accordance with any provision of this Trust
Agreement (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to such Trustee's negligence, bad faith or
willful misconduct (or, in the case of the Administrative Trustees or the
Delaware Trustee, any such expense, disbursement or advance as may be
attributable to its, his or her gross negligence, bad faith or willful
misconduct); and

   (c)  to indemnify each of the Trustees or any predecessor Trustee for, and
to hold the Trustees harmless against, any loss, damage, claims, liability,
penalty or expense incurred without negligence or bad faith on its part, arising
out of or in connection with the acceptance or administration of this Trust
Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder, except any such expense, disbursement or advance as
may be attributable to such Trustee's negligence, bad faith or willful
misconduct (or, in the case of the Administrative Trustees or the Delaware
Trustee, any such expense, disbursement or advance as may be attributable to
its, his or her gross negligence, bad faith or willful misconduct).

   No Trustee may claim any Lien or charge on any Trust Property as a result of
any amount due pursuant to this Section 806.

   SECTION 807.  CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

   (a)  There shall at all times be a Property Trustee hereunder with respect
to the Trust Securities. The Property Trustee shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has a combined capital
and surplus of at least $50,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 807,
the combined 


                                      35

<PAGE>

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 the Property Trustee with respect to the Trust Securities 
shall cease to be eligible in accordance with the provisions of this Section 
807, it shall resign immediately in the manner and with the effect 
hereinafter specified in this Article VIII.

   (b) There shall at all times be one or more Administrative Trustees 
hereunder with respect to the Trust Securities. Each Administrative Trustee

entity.

   (c) There shall at all times be a Delaware Trustee with respect to the 
Trust Securities. The Delaware Trustee shall either be (i) a natural person 
who is at least 21 years of age and a resident of the State of Delaware; or 
(ii) a legal entity with its principal place of business in the State of 
Delaware and that otherwise meets the requirements of applicable Delaware law 
that shall act through one or more persons authorized to bind such entity.

   SECTION 808.  CONFLICTING INTERESTS.

   If the Property Trustee has or shall acquire a conflicting interest within 
the meaning of the Trust Indenture Act, the Property Trustee shall either 
eliminate such interest or resign, to the extent and in the manner provided 
by, and subject to the provisions of, the Trust Indenture Act and this Trust 
Agreement.

   SECTION 809.  CO-TRUSTEES AND SEPARATE TRUSTEE.

   (a) Unless an Event of Default shall have occurred and be continuing, at 
any time or times, for the purpose of meeting the legal requirements of the 
Trust Indenture Act or of any jurisdiction in which any part of the Trust 
Property may at the time be located, the Depositor shall have power to 
appoint, and upon the written request of the Property Trustee, the Depositor 
shall for such purpose join with the Property Trustee in the execution, 
delivery and performance of all instruments and agreements necessary or 
proper to appoint, one or more Persons approved by the Property Trustee 
either to act as co-trustee, jointly with the Property Trustee, of all or any 
part of such Trust Property, or to the extent required by law to act as 
separate trustee of any such property, in either case with such powers as may 
be provided in the instrument of appointment, and to vest in such Person or 
Persons in the capacity aforesaid, any property, title, right or power deemed 
necessary or desirable, subject to the other provisions of this Section 809. 
If the Depositor does not join in such appointment within 15 days after the 
receipt by it of a request so to do, or in case a Debenture Event of Default 
has occurred and is continuing, the Property Trustee alone shall have power 
to make such appointment. Any co-trustee or separate trustee appointed 
pursuant to this Section 809 shall either be (i) a natural person who is at 
least 21 years of age and a resident of the United States; or (ii) a legal 
entity with its principal place of business in the United States that shall 
act through one or more persons authorized to bind such entity.

   (b) Should any written instrument from the Depositor be required by any 
co-trustee or separate trustee so appointed for more fully confirming to such 
co-trustee or separate trustee such 

                                      36
<PAGE>

property, title, right, or power, any and all such instruments shall, on 
request, be executed, acknowledged, and delivered by the Depositor.

   (c) Every co-trustee or separate trustee shall, to the extent permitted by 
law, but to such extent only, be appointed subject to the following terms, 
namely:

    (i)   The Trust Securities shall be executed and delivered and all 
rights, powers, duties and obligations hereunder in respect of the custody of 
securities, cash and other personal property held by, or required to be 
deposited or pledged with, the Trustees specified hereunder, shall be 
exercised, solely by such Trustees and not by such co-trustee or separate 
trustee.

    (ii)  The rights, powers, duties and obligations hereby conferred or 
imposed upon the Property Trustee in respect of any property covered by such 
appointment shall be conferred or imposed upon and exercised or performed by 
the Property Trustee or by the Property Trustee and such co-trustee or 
separate trustee jointly, as shall be provided in the instrument appointing 
such co-trustee or separate trustee, except to the extent that under any law 
of any jurisdiction in which any particular act is to be performed, the 
Property Trustee shall be incompetent or unqualified to perform such act, in 
which event such rights, powers, duties and obligations shall be exercised 
and performed by such co-trustee or separate trustee.

    (iii) The Property Trustee at any time, by an instrument in writing 
executed by it, with the written concurrence of the Depositor, may accept the 
resignation of or remove any co-trustee or separate trustee appointed under 
this Section 809, and, in case a Debenture Event of Default has occurred and 
is continuing, the Property Trustee shall have the power to accept the 
resignation of, or remove, any such co-trustee or separate trustee without 
the concurrence of the Depositor. Upon the written request of the Property 
Trustee, the Depositor shall join with the Property Trustee in the execution, 
delivery and performance of all instruments and agreements necessary or 
proper to effectuate such resignation or removal. A successor to any 
co-trustee or separate trustee so resigned or removed may be appointed in the 
manner provided in this Section 809.

    (iv)  No co-trustee or separate trustee hereunder shall be personally 
liable by reason of any act or omission of the Property Trustee or any other 
trustee hereunder.

    (v)   The Property Trustee shall not be liable by reason of any act of a 
co-trustee or separate trustee.

    (vi)  Any Act of the Holders delivered to the Property Trustee shall be 
deemed to have been delivered to each such co-trustee and separate trustee.

   SECTION 810.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

   (a) No resignation or removal of any Trustee (the "Relevant Trustee") and 
no appointment of a successor Trustee pursuant to this Article VIII shall 
become effective until the acceptance of appointment by the successor Trustee 
in accordance with the applicable requirements of Section 811.

                                      37
<PAGE>

   (b) Subject to the immediately preceding paragraph, the Relevant Trustee 
may resign at any time with respect to the Trust Securities by giving written 
notice thereof to the Securityholders. If the instrument of acceptance by the 
successor Trustee required by Section 811 shall not have been delivered to 
the Relevant Trustee within 30 days after the giving of such notice of 
resignation, the Relevant Trustee may petition, at the expense of the 
Depositor, any court of competent jurisdiction for the appointment of a 
successor Relevant Trustee with respect to the Trust Securities.

   (c) Unless a Debenture Event of Default shall have occurred and be 
continuing, any Trustee may be removed at any time by an Act of the Common 
Securityholder. If a Debenture Event of Default shall have occurred and be 
continuing, the Property Trustee or the Delaware Trustee, or both of them, 
may be removed at such time by an Act of the Holders of a majority in 
Liquidation Amount of the Preferred Securities, delivered to the Relevant 
Trustee (in its individual capacity and on behalf of the Trust). An 
Administrative Trustee may be removed by the Common Securityholder at any 
time.

   (d) If any Trustee shall resign, be removed or become incapable of acting 
as Trustee, or if a vacancy shall occur in the office of any Trustee for any 
cause, at a time when no Debenture Event of Default shall have occurred and 
be continuing, the Common Securityholder, by an Act of the Common 
Securityholder delivered to the retiring Trustee, shall promptly appoint a 
successor Trustee or Trustees with respect to the Trust Securities and the 
Trust, and the successor Trustee shall comply with the applicable 
requirements of Section 811. If the Property Trustee or the Delaware Trustee 
shall resign, be removed or become incapable of continuing to act as the 
Property Trustee or the Delaware Trustee, as the case may be, at a time when 
a Debenture Event of Default shall have occurred and is continuing, the 
Preferred Securityholders, by an Act of the Securityholders of a majority in 
Liquidation Amount of the Preferred Securities then Outstanding delivered to 
the retiring Relevant Trustee, shall promptly appoint a successor Relevant 
Trustee or Trustees with respect to the Trust Securities and the Trust, and 
such successor Trustee shall comply with the applicable requirements of 
Section 811. If an Administrative Trustee shall resign, be removed or become 
incapable of acting as an Administrative Trustee, at a time when a Debenture 
Event of Default shall have occurred and be continuing, the Common 
Securityholder, by an Act of the Common Securityholder delivered to an 
Administrative Trustee, shall promptly appoint a successor Administrative 
Trustee or Administrative Trustees with respect to the Trust Securities and 
the Trust, and such successor Administrative Trustee or Administrative 
Trustees shall comply with the applicable requirements of Section 811. If no 
successor Relevant Trustee with respect to the Trust Securities shall have 
been so appointed by the Common Securityholder or the Preferred 
Securityholders and accepted appointment in the manner required by Section 
811, any Securityholder who has been a Securityholder of Trust Securities for 
six consecutive months on behalf of himself and all others similarly situated 
may petition a court of competent jurisdiction for the appointment of a 
successor Relevant Trustee with respect to the Trust Securities.

   (e) The Property Trustee shall give notice of each resignation and each 
removal of a Trustee and each appointment of a successor Trustee to all the 
Securityholders in the manner provided in Section 1008 and shall give notice 
to the Depositor. Each notice shall include the name of the 

                                      38
<PAGE>

successor Relevant Trustee and the address of its Corporate Trust Office if 
it is the Property Trustee.

   (f) Notwithstanding the foregoing or any other provision of this Trust 
Agreement, in the event any Administrative Trustee or a Delaware Trustee who 
is a natural person dies or becomes, in the opinion of the Depositor, 
incompetent or incapacitated, the vacancy created by such death, incompetence 
or incapacity may be filled by (a) the unanimous act of the remaining 
Administrative Trustees if there are at least two of them; or (b) otherwise 
by the Depositor (with the successor in each case being a Person who 
satisfies the eligibility requirement for Administrative Trustees set forth 
in Section 807).

   SECTION 811.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

   (a) In case of the appointment hereunder of a successor Relevant Trustee 
with respect to the Trust Securities and the Trust, the retiring Relevant 
Trustee and each successor Relevant Trustee with respect to the Trust 
Securities shall execute and deliver an instrument hereto wherein each 
successor Relevant Trustee shall accept such appointment and which shall 
contain such provisions as shall be necessary or desirable to transfer and 
confirm to, and to vest in, each successor Relevant Trustee all the rights, 
powers, trusts and duties of the retiring Relevant Trustee with respect to 
the Trust Securities and the Trust and upon the execution and delivery of 
such instrument the resignation or removal of the retiring Relevant Trustee 
shall become effective to the extent provided therein and each such successor 
Relevant Trustee, without any further act, deed or conveyance, shall become 
vested with all the rights, powers, trusts and duties of the retiring 
Relevant Trustee with respect to the Trust Securities and the Trust; but, on 
request of the Trust or any successor Relevant Trustee such retiring Relevant 
Trustee shall duly assign, transfer and deliver to such successor Relevant 
Trustee all the Trust Property, all proceeds thereof and money held by such 
retiring Relevant Trustee hereunder with respect to the Trust Securities and 
the Trust.

   (b) Upon request of any such successor Relevant Trustee, the Trust shall 
execute any and all instruments for more fully and certainly vesting in and 
confirming to such successor Relevant Trustee all such rights, powers and 
trusts referred to in the immediately preceding paragraph, as the case may be.

   (c) No successor Relevant Trustee shall accept its appointment unless at 
the time of such acceptance such successor Relevant Trustee shall be 
qualified and eligible under this Article VIII.

   SECTION 812.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

   Any Person into which the Property Trustee, the Delaware Trustee or any 
Administrative Trustee may be merged or converted or with which it may be 
consolidated, or any Person resulting from any merger, conversion or 
consolidation to which such Relevant Trustee shall be a party, or any 
corporation succeeding to all or substantially all the corporate trust 
business of such Relevant Trustee, shall be the successor of such Relevant 
Trustee hereunder, provided such 

                                      39
<PAGE>

Person shall be otherwise qualified and eligible under this Article VIII, 
without the execution or filing of any paper or any further act on the part 
of any of the parties hereto.

   SECTION 813.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE DEPOSITOR OR 
THE TRUST.

   If and when the Property Trustee or the Delaware Trustee shall be or 
become a creditor of the Depositor or the Trust (or any other obligor upon 
the Debentures or the Trust Securities), the Property Trustee or the Delaware 
Trustee, as the case may be, shall be subject to and shall take all actions 
necessary in order to comply with the provisions of the Trust Indenture Act 
regarding the collection of claims against the Depositor or the Trust (or any 
such other obligor).

   SECTION 814.  REPORTS BY THE PROPERTY TRUSTEE.

   (a) The Property Trustee shall transmit to the Securityholders such 
reports concerning the Property Trustee, its actions under this Trust 
Agreement and the property and funds in its possession as the Property 
Trustee as may be required pursuant to the Trust Indenture Act at the times 
and in the manner provided pursuant thereto.

   (b) A copy of each such report shall, at the time of such transmission to 
the Holders, be filed by the Property Trustee with the Nasdaq National 
Market, and each national securities exchange or other organization upon 
which the Trust Securities are listed, and also with the Commission and the 
Depositor.

   SECTION 815.  REPORTS TO THE PROPERTY TRUSTEE.

   The Depositor and the Administrative Trustees on behalf of the Trust shall 
provide to the Property Trustee such documents, reports and information as 
required by Section 314 of the Trust Indenture Act (if any) and the 
compliance certificate required by Section 314(a) of the Trust Indenture Act 
in the form, in the manner and at the times required by Section 314 of the 
Trust Indenture Act.

   SECTION 816.  EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

   Each of the Depositor and the Administrative Trustees on behalf of the 
Trust shall provide to the Property Trustee such evidence of compliance with 
any conditions precedent, if any, provided for in this Trust Agreement that 
relate to any of the matters set forth in Section 314(c) of the Trust 
Indenture Act. Any certificate or opinion required to be given by an officer 
pursuant to Section 314(c)(1) of the Trust Indenture Act shall be given in 
the form of an Officers' Certificate.

   SECTION 817.  NUMBER OF TRUSTEES.

   (a) The number of Trustees shall be five, provided that the Holder of all 
of the Common Securities by written instrument may increase or decrease the 
number of the Administrative Trustees. The Property Trustee and the Delaware 
Trustee may be the same Person.

                                       40
<PAGE>

   (b) If a Trustee ceases to hold office for any reason and the number of 
the Administrative Trustees is not reduced pursuant to Section 817(a), or if 
the number of the Trustees is increased pursuant to Section 817(a), a vacancy 
shall occur. The vacancy shall be filled with a Trustee appointed in 
accordance with Section 810.

   (c) The death, resignation, retirement, removal, bankruptcy, incompetence 
or incapacity to perform the duties of a Trustee shall not operate to annul 
the Trust. Whenever a vacancy in the number of the Administrative Trustees 
shall occur, until such vacancy is filled by the appointment of an 
Administrative Trustee in accordance with Section 810, the Administrative 
Trustees in office, regardless of their number (and notwithstanding any other 
provision of this Agreement), shall have all the powers granted to the 
Administrative Trustees and shall discharge all the duties imposed upon the 
Administrative Trustees by this Trust Agreement.

   SECTION 818.  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 purpose of executing any documents contemplated in 
Section 207(a); and

   (b) The Administrative Trustees shall have power to delegate from time to 
time to such of their number or to the Depositor the doing of such things and 
the execution of such instruments either in the name of the Trust or the

Trustees may deem expedient, to the extent such delegation is not prohibited 
by applicable law or contrary to the provisions of the Trust, as set forth 
herein.

   Except as otherwise provided in this Trust Agreement, the consent or 
approval of the Administrative Trustees shall require consent or approval by 
not less than a majority of the Administrative Trustees, unless there are

                     TERMINATION, LIQUIDATION AND MERGER
                                       
   SECTION 901.  TERMINATION UPON EXPIRATION DATE.

   Unless earlier dissolved, the Trust shall automatically dissolve 
_______________, 2052 (the "Expiration Date") subject to distribution of the 
Trust Property in accordance with Section 904.

   SECTION 902.  EARLY TERMINATION.

   The first to occur of any of the following events is an "Early Termination 
Event:"

   (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution 
or liquidation of, the Depositor;

                                       41
<PAGE>

   (b) delivery of written direction to the Property Trustee by the Depositor 
at any time (which direction is wholly optional and within the discretion of 
the Depositor) to dissolve the Trust and distribute the Debentures to the 
Securityholders in exchange for the Preferred Securities in accordance with 
Section 904;

   (c) the redemption of all of the Preferred Securities in connection with 
the redemption of all of the Debentures; and

   (d) the entrance of an order for dissolution of the Trust by a court of 
competent jurisdiction.

   SECTION 903.  TERMINATION.

   The respective obligations and responsibilities of the Trustees and the 
Trust created and continued hereby shall terminate upon the latest to occur 
of the following:  (a) the distribution by the Property Trustee to the 
Securityholders upon the liquidation of the Trust pursuant to Section 904, or 
upon the redemption of all of the Trust Securities pursuant to Section 402, 
of all amounts required to be distributed hereunder upon the final payment of 
the Trust Securities; (b) the payment of any expenses owed by the Trust; (c) 
the discharge of all administrative duties of the Administrative Trustees, 
including the performance of any tax reporting obligations with respect to 
the Trust or the Securityholders; and (d) the filing of a Certificate of 
Cancellation by the Administrative Trustee under the Delaware Business Trust 
Act.

   SECTION 904.  LIQUIDATION.

   (a) If an Early Termination Event specified in clause (a), (b), or (d) of 
Section 902 occurs or upon the Expiration Date, the Trust shall be liquidated 
by the Trustees as expeditiously as the Trustees determine to be possible by 
distributing, after satisfaction of liabilities to creditors of the Trust as 
provided by applicable law, to each Securityholder a Like Amount of 
Debentures, subject to Section 904(d). Notice of liquidation shall be given 
by the Property Trustee by first-class mail, postage prepaid, mailed not 
later than 30 nor more than 60 days prior to the Liquidation Date to each 
Holder of Trust Securities at such Holder's address appearing in the 
Securities Register. All notices of liquidation shall:

    (i)   state the Liquidation Date;

    (ii)  state that from and after the Liquidation Date, the Trust 
Securities shall no longer be deemed to be Outstanding and any Trust 
Securities Certificates not surrendered for exchange shall be deemed to 
represent a Like Amount of Debentures; and

    (iii) provide such information with respect to the mechanics by which the 
Holders may exchange the Trust Securities Certificates for the Debentures, 
or, if Section 904(d) applies, receive a Liquidation Distribution, as the 
Administrative Trustees or the Property Trustee shall deem appropriate.

   (b) Except where Section 902(c) or 904(d) applies, in order to effect the 
liquidation of the Trust and distribution of the Debentures to the 
Securityholders, the Property Trustee shall 

                                      42
<PAGE>

establish a record date for such distribution (which shall be not more than 
45 days prior to the Liquidation Date) and, either itself acting as exchange 
agent or through the appointment of a separate exchange agent, shall 
establish such procedures as it shall deem appropriate to effect the 
distribution of Debentures in exchange for the Outstanding Trust Securities 
Certificates.

   (c) Except where Section 902(c) or 904(d) applies, after the Liquidation 
Date, (i) the Trust Securities shall no longer be deemed to be outstanding; 
(ii) certificates representing a Like Amount of the Debentures shall be 
issued to the Holders of Trust Securities Certificates upon surrender of such 
certificates to the Administrative Trustees or their agent for exchange; 
(iii) the Depositor shall use its reasonable efforts to have the Debentures 
listed on the Nasdaq National Market or on such other securities exchange or 
other organization as the Preferred Securities are then listed or traded; 
(iv) any Trust Securities Certificates not so surrendered for exchange shall 
be deemed to represent a Like Amount of Debentures, accruing interest at the 
rate provided for in the Debentures from the last Distribution Date on which 
a Distribution was made on such Trust Securities Certificates until such 
certificates are so surrendered (and until such certificates are so 
surrendered, no payments of interest or principal shall be made to Holders of 
the Trust Securities Certificates with respect to such Debentures); and (v) 
all rights of the Securityholders holding the Trust Securities shall cease, 
except the right of such Securityholders to receive the Debentures upon 
surrender of the Trust Securities Certificates.

   (d) In the event that, notwithstanding the other provisions of this 
Section 904, whether because of an order for dissolution entered by a court 
of competent jurisdiction or otherwise, distribution of the Debentures in the 
manner provided herein is determined by the Property Trustee not to be 
practical, the Trust Property shall be liquidated, and the Trust shall be 
dissolved, wound-up or terminated, by the Property Trustee in such manner as 
the Property Trustee determines. In such event, on the date of the 
dissolution, winding-up or other termination of the Trust, the 
Securityholders shall be entitled to receive out of the assets of the Trust 
available for distribution to the Securityholders, after satisfaction of 
liabilities to creditors of the Trust as provided by applicable law, an 
amount equal to the Liquidation Amount per Trust Security plus accumulated 
and unpaid Distributions thereon to the date of payment (such amount being 
the "Liquidation Distribution"). If, upon any such dissolution, winding-up or 
termination, the Liquidation Distribution can be paid only in part because 
the Trust has insufficient assets available to pay in full the aggregate 
Liquidation Distribution, then, subject to the next succeeding sentence, the 
amounts payable by the Trust on the Trust Securities shall be paid on a pro 
rata basis (based upon Liquidation Amounts, subject to Section 407). The 
Holder of the Common Securities shall be entitled to receive the Liquidation 
Distributions upon any such dissolution, winding-up or termination pro rata 
(determined as aforesaid) with the Holders of the Preferred Securities, 
except that, if a Debenture Event of Default has occurred and is continuing, 
the Preferred Securities shall have a priority over the Common Securities.

   SECTION 905.  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 its properties and assets 
substantially as an entirety to any corporation or 

                                      43
<PAGE>

other Person, except pursuant to this Section 905. At the request of the 
Depositor, with the consent of the Administrative Trustees and without the 
consent of the Holders of the Preferred Securities, the Property Trustee or 
the Delaware Trustee, the Trust may merge with or into, consolidate, 
amalgamate, be replaced by or convey, transfer or lease its properties and 
assets substantially as an entirety to a trust organized as such under the 
laws of any State; provided, that (i) such successor entity either (a) 
expressly assumes all of the obligations of the Trust with respect to the 
Preferred Securities; or (b) substitutes for the Preferred Securities other 
securities having substantially the same terms as the Preferred Securities 
(the "Successor Securities") so long as the Successor Securities rank the 
same as the Preferred Securities rank in priority with respect to 
distributions and payments upon liquidation, redemption and otherwise; (ii) 
the Depositor expressly appoints a trustee of such successor entity 
possessing substantially the same powers and duties as the Property Trustee 
as the holder of the Debentures; (iii) the Successor Securities are listed or 
traded, or any Successor Securities shall be listed or traded upon 
notification of issuance, on any national securities exchange or other 
organization on which the Preferred Securities are then listed, if any; (iv) 
such merger, consolidation, amalgamation, replacement, conveyance, transfer 
or lease does not adversely affect the rights, preferences and privileges of 
the Holders of the Preferred Securities (including any Successor Securities) 
in any material respect; (v) prior to such merger, consolidation, 
amalgamation, replacement, conveyance, transfer or lease, the Depositor has 
received an Opinion of Counsel to the effect that (a) such merger, 
consolidation, amalgamation, replacement, conveyance, transfer or lease does 
not adversely affect the rights, preferences and privileges of the Holders of 
the Preferred Securities (including any Successor Securities) in any material 
respect; and (b) following such merger, consolidation, amalgamation, 
replacement, conveyance, transfer or lease, neither the Trust nor such 
successor entity shall be required to register as an "investment company" 
under the Investment Company Act; and (vi) the Depositor owns all of the 
Common Securities of such successor entity and guarantees the obligations of 
such successor entity under the Successor Securities at least to the extent 
provided by the Guarantee, the Debentures, the Indenture, this Trust 
Agreement and the Expense Agreement. Notwithstanding the foregoing, the Trust 
shall not, except with the consent of the Holders of 100% in Liquidation 
Amount of the Preferred Securities, consolidate, amalgamate, merge with or 
into, or be replaced by or convey, transfer or lease its properties and 
assets substantially as an entirety to any other Person or permit any other 
Person to consolidate, amalgamate, merge with or into, or replace it if such 
consolidation, amalgamation, merger or replacement would cause the Trust or 
the successor entity to be classified as other than a grantor trust for 
United States federal income tax purposes.

   SECTION 1001.  LIMITATION OF RIGHTS OF THE SECURITYHOLDERS.

   The death or incapacity of any Person having an interest, beneficial or 
otherwise, in the Trust Securities shall not operate to terminate this Trust 
Agreement, nor entitle the legal representatives or heirs of such Person or 
any Securityholder for such Person to claim an accounting, take any action or 
bring any proceeding in any court for a partition or winding-up of the 
arrangements contemplated hereby, nor otherwise affect the rights, 
obligations and liabilities of the parties hereto or any of them.

   SECTION 1002.  AMENDMENT.

   (a) This Trust Agreement may be amended from time to time by the Trustees 
and the Depositor, without the consent of any Securityholders, (i) as 
provided in Section 811 with respect to acceptance of appointment by a 
successor Trustee; (ii) to cure any ambiguity, correct or supplement any 
provision herein or therein which may be inconsistent with any other 
provision herein or therein, or to make any other provisions with respect to 
matters or questions arising under this Trust Agreement, that shall not be 
inconsistent with the other provisions of this Trust Agreement; (iii) to 
modify, eliminate or add to any provisions of this Trust Agreement to such 
extent as shall be necessary to ensure that the Trust shall be classified for 
United States federal income tax purposes as a grantor trust at all times 
that any of the Trust Securities are outstanding or to ensure that the Trust 
shall not be required to register as an "investment company" under the 
Investment Company Act; or (iv) to reduce or increase the Liquidation Amount 
per Trust Security and simultaneously to correspondingly increase or decrease 
the number of Trust Securities issued and outstanding solely for the purpose 
of maintaining the eligibility of the Preferred Securities for quotation or 
listing on any national securities exchange or other organization on which 
the Preferred Securities are then quoted or listed (including, if applicable, 
the Nasdaq National Market); provided, however, that in the case of clause 
(ii), such action shall not adversely affect in any material respect the 
interests of any Securityholder, and provided further, that in the case of 
clause (iv) the aggregate Liquidation Amount of the Trust Securities 
outstanding upon completion of any such reduction must be the same as the 
aggregate Liquidation Amount of the Trust Securities outstanding immediately 
prior to such reduction or increase, and any amendments of this Trust 
Agreement shall become effective when notice thereof is given to the 
Securityholders (or, in the case of an amendment pursuant to clause (iv), as 
of the date specified in the notice).

   (b) Except as provided in Section 601(c) or Section 1002(c) hereof, any 
provision of this Trust Agreement may be amended by the Trustees and the 
Depositor (i) with the consent of the Trust Securityholders representing not 
less than a majority (based upon Liquidation Amounts) of the Trust Securities 
then Outstanding; and (ii) upon 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 shall not affect 
the Trust's status as a grantor trust for United 

                                      45
<PAGE>

States federal income tax purposes or the Trust's exemption from status of an 
"investment company" under the Investment Company Act.

   (c) In addition to and notwithstanding any other provision in this Trust 
Agreement, without the consent of each affected Securityholder (such consent 
being obtained in accordance with Section 603 or 606 hereof), this Trust 
Agreement may not be amended to (i) change the amount or timing of any 
Distribution on the Trust Securities or otherwise adversely affect the amount 
of any Distribution required to be made in respect of the Trust Securities as 
of a specified date; or (ii) restrict the right of a Securityholder to 
institute suit for the enforcement of any such payment on or after such date; 
notwithstanding any other provision herein, without the unanimous consent of 
the Securityholders (such consent being obtained in accordance with Section 
603 or 606 hereof), this paragraph (c) of this Section 1002 may not be 
amended.

   (d) Notwithstanding any other provisions of this Trust Agreement, no 
Trustee shall enter into or consent to any amendment to this Trust Agreement 
which would cause the Trust to fail or cease to qualify for the exemption 
from status of an "investment company" under the Investment Company Act or to 
fail or cease to be classified as a grantor trust for United States federal 
income tax purposes.

   (e) Notwithstanding anything in this Trust Agreement to the contrary, 
without the consent of the Depositor, this Trust Agreement may not be amended 
in a manner which imposes any additional obligation on the Depositor.

   (f) In the event that any amendment to this Trust Agreement is made, the 
Administrative Trustees shall promptly provide to the Depositor a copy of 
such amendment.

   (g) Upon the request of the Depositor, accompanied by its board 
resolutions authorizing the execution of any such amendments to this Trust 
Agreement, and upon the filing with the Property Trustee and the Delaware 
Trustee of evidence of the consent of the Securityholders required to consent 
thereto as aforesaid, the Property Trustee and the Delaware Trustee shall 
join with the Depositor in the execution of such amendment to this Trust 
Agreement unless such amendment affects the Property Trustee's or the 
Delaware Trustee's own rights, duties, immunities under this Trust Agreement 
or otherwise in which case the Property Trustee and Delaware Trustee may in 
their own discretion but shall not be obligated to enter into such amendment 
to this Trust Agreement. The Property Trustee and Delaware Trustee, subject 
to the provisions of Section 801, may receive an Opinion of Counsel as 
conclusive evidence that any amendment to this Trust Agreement executed 
pursuant to this Article X is authorized or permitted by, and conforms to, 
the terms of this Article X and that it is proper for the Property Trustee 
and Delaware Trustee under the provisions of this Article X to join in the 
execution thereof.

LAWS PRINCIPLES).

   SECTION 1005.  PAYMENTS DUE ON NON-BUSINESS DAY.

   If the date fixed for any payment on any Trust Security shall be a day

   SECTION 1009.  AGREEMENT NOT TO PETITION.

   Each of the Trustees and the Depositor agrees for the benefit of the 
Securityholders that, until at least one year and 1 day after the Trust has 
been terminated in accordance with Article IX, they shall not file, or join 
in the filing of, a petition against the Trust under any bankruptcy, 
insolvency, reorganization or other similar law (including, without 
limitation, the United States Bankruptcy Code of 1978, as amended) 
(collectively, "Bankruptcy Laws") or otherwise join in the commencement of 
any proceeding against the Trust under any Bankruptcy Law. In the event the 
Depositor takes action in violation of this Section 1009, the Property 
Trustee agrees, for the benefit of the Securityholders, that at the expense 
of the Depositor (which expense shall be paid prior to the filing), it shall 
file an answer with the bankruptcy court or otherwise properly contest the 
filing of such petition by the Depositor against the Trust or the 
commencement of such action and raise the defense that the Depositor has 
agreed in writing not to take such action and should be stopped and precluded 
therefrom. The provisions of this Section 1009 shall survive the termination 
of this Trust Agreement.

   SECTION 1010.  TRUST INDENTURE ACT; CONFLICT WITH TRUST INDENTURE ACT.

   (a) This Trust Agreement is subject to the provisions of the Trust

to the extent applicable, be governed by such provisions.

   (b) The Property Trustee shall be the only Trustee which is a trustee for 
the purposes of the Trust Indenture Act.

   (c) If any provision hereof limits, qualifies or conflicts with another 
provision hereof which is required to be included in this Trust Agreement by 
any of the provisions of the Trust Indenture Act, such required provision 
shall control. If any provision of this Trust Agreement modifies or excludes 
any provision of the Trust Indenture Act which may be so modified or 
excluded, the latter provision shall be deemed to apply to this Trust 
Agreement as so modified or to be excluded, as the case may be.

AND THE INDENTURE.

   THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN BY

Preferred Guarantee Trustee in good faith determines that the withholding of 
such notice is in the interests of the Holders of the Preferred Securities.

   (b) The Preferred Guarantee Trustee shall not be deemed to have knowledge 
of any Event of Default unless the Preferred Guarantee Trustee shall have

   (a) This Preferred Securities Guarantee shall be held by the Preferred 
Guarantee Trustee for the benefit of the Holders of the Preferred Securities, 
and the Preferred Guarantee Trustee shall not transfer this Preferred

exercising his or her rights pursuant to Section 5.4(b) or to a Successor 
Preferred Guarantee Trustee on acceptance by such Successor Preferred 
Guarantee Trustee of its appointment to act as Successor Preferred Guarantee 
Trustee. The right, title and interest of the Preferred Guarantee Trustee

such vesting and cessation of title shall be effective whether or not 
conveyancing documents have been executed and delivered pursuant to the 
appointment of such Successor Preferred Guarantee Trustee.

   (c)   The Preferred Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Preferred Securities Guarantee, and no implied covenants shall be read into
this Preferred Securities Guarantee against the Preferred 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
Preferred Guarantee Trustee, the Preferred Guarantee Trustee shall exercise such
of the rights and powers vested in it by this Preferred Securities Guarantee,
and use the same degree of care and skill in its exercise thereof, as a prudent
person would exercise or use under the circumstances in the conduct of his or
her own affairs.

   (d)   No provision of this Preferred Securities Guarantee shall be construed
to relieve the Preferred Guarantee 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 any Event of Default and after the curing
or waiving of all such Events of Default that may have occurred:

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

       (B)  in the absence of bad faith on the part of the Preferred
Guarantee Trustee, the Preferred Guarantee Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon any certificates or opinions furnished to the Preferred Guarantee
Trustee and conforming to the requirements of this Preferred Securities
Guarantee; but in the case of any such certificates or opinions that by any
provision hereof are specifically required to be furnished to the Preferred
Guarantee Trustee, the Preferred Guarantee Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Preferred Securities Guarantee;

    (ii) the Preferred Guarantee Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer of the Preferred Guarantee
Trustee, unless it shall be proved that the Preferred Guarantee Trustee was
negligent in ascertaining the pertinent facts upon which such judgment was made;

    (iii)  the Preferred Guarantee 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 Holders of not less than a Majority in Liquidation
Amount of the Preferred Securities relating to the time, method and place of
conducting any proceeding for any remedy available to the Preferred Guarantee
Trustee, or exercising any trust or power conferred upon the Preferred Guarantee
Trustee under this Preferred Securities Guarantee; and


                                       7

<PAGE>

    (iv) no provision of this Preferred Securities Guarantee shall require the
Preferred 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 Preferred Guarantee Trustee
shall have reasonable grounds for believing that the repayment of such funds or
liability is not reasonably assured to it under the terms of this Preferred
Securities Guarantee or indemnity, reasonably satisfactory to the Preferred
Guarantee Trustee, against such risk or liability is not reasonably assured to
it.

administration of this Preferred Securities Guarantee from any court of
competent jurisdiction;

    (vi) the Preferred Guarantee Trustee shall be under no obligation to
exercise any of the rights or powers vested in it by this Preferred Securities
Guarantee at the request or direction of any Holder, unless such Holder shall

expenses (including attorneys' fees and expenses and the expenses of the
Preferred Guarantee Trustee's agents, nominees or custodians) and liabilities
that might be incurred by it in complying with such request or direction,

<PAGE>

requested by the Preferred Guarantee Trustee; provided that, nothing

Preferred Guarantee Trustee, upon the occurrence of an Event of 
Default, of its obligation to exercise the rights and powers vested 
in it by this Preferred Securities Guarantee;

    (vii)  the Preferred Guarantee Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,

document, but the Preferred Guarantee Trustee, in its discretion, may make such

may refrain from enforcing such remedy or right or taking such other action
until such instructions are received, and (iii) shall be protected in

impose any duty or obligation on the Preferred Guarantee 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
Preferred Guarantee 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 Preferred Guarantee Trustee shall be construed to be a duty.

SECTION 3.3. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE.

                              EMPLOYMENT AGREEMENT
 
    THIS EMPLOYMENT AGREEMENT  ("Agreement") is made and entered into as of the
10th day of October, 1995 by and between Indiana United Bancorp, an Indiana
corporation (together with its successors and assigns permitted under this
Agreement, the "Company") and Michael K. Bauer (the "Executive"). Regional
Federal Savings Bank (the "Bank"), a wholly owned subsidiary of the Company,
joins in this Agreement for the purposes expressed herein.
 
RECITALS:
 
A. Executive has made and is expected to continue to make substantial
    contributions in maintaining high quality assets, enhancing customer
    service, improving productivity and/or operating efficiency, generating loan
    and deposit growth, and/or other contributions favorably impacting the
    financial performance of the Company. Executive's contributions have
    occurred while serving as Bank's Chief Executive Officer.
 
B.  The Company believes the continued services of Executive to be in the best
    interests of the Company, its shareholders and the Bank, and desires to
    enter into this Agreement to assure for a certain minimum period the
    continued services of Executive free of the distractions of an actual or
    potential Change of Control.
 
C.  The Bank desires to join in this Agreement to evidence its consent to the
    provisions herein and its willingness to perform in accordance with all such
    provisions as they relate to the Bank.
 
D. Executive desires to enter into this Agreement to assure a fair and
    reasonable transition period for Change of Control principals to evaluate
    Executive's past performance and to determine how to best maximize his
    future value to Company or Bank, subject to the terms and provisions of this
    Agreement.
 
E.  The parties intend certain capitalized terms not otherwise defined to have
    the meanings assigned to them in Section 26 of this Agreement.
 
AGREEMENT:
 
    NOW, THEREFORE,  in consideration of the premises and mutual covenants
contained herein and for other good and valuable considerations, the receipt of
which is mutually acknowledged, the Company, the Bank and the Executive
(individually, a "Party" and collectively, the "Parties") agree as follows:
 
1.  AT-WILL EMPLOYMENT.  The Company, the Bank and the Executive mutually
    acknowledge and agree that Executive is employed as an at-will employee and,
    notwithstanding contrary provisions of this Agreement, is entitled only to
    the rights afforded all at-will employees in the state of Indiana, together
    with all rights afforded under federal discrimination laws. Executive
    expressly acknowledges that the obligations and responsibilities of Company
    created by this Agreement shall be applicable only in the event of a Change
    of Control.
 
2.  TERM OF THIS AGREEMENT.  This Agreement shall be effective upon its
    execution by the Parties and shall expire on September 30, 1998.
 
    a)  TERMINATION OF AGREEMENT BY EXECUTIVE:  This Agreement may be terminated
       at any time by Executive upon six months written notice to Bank.
 
    b)  EFFECT OF TERMINATION:  A notice of termination by Executive shall
       immediately and unconditionally release all other Parties from any
       obligation specifically created by this Agreement.
 
    c)  TERMINATION BY MUTUAL CONSENT:  All Parties may agree by mutual written
       consent to terminate or modify this Agreement at any time, with or
       without consideration.
 
3.  POSITION, DUTIES AND RESPONSIBILITIES DURING THE TERM OF THIS AGREEMENT.
 
    a)  Executive shall be employed by Bank as its Chief Executive Officer, (or
       in a position of similar scope, responsibility and authority), and shall
       serve as a member of the Bank's board of directors
<PAGE>
       (the "Bank Board"). The Executive, in carrying out his duties under this
       Agreement, shall report to the Bank Board.
 
    b)  Executive shall engage in charitable activities and community affairs,
       provided that such activities are likely to enhance the image of Bank and
       do not materially interfere with the proper performance of his duties and
       responsibilities as Chief Executive Officer (or any other position
       similar in scope, responsibility and authority).
 
4.  BASE SALARY.  The Executive shall be paid an annualized Base Salary of
    $120,000.00, payable in accordance with the regular payroll practices of
    Bank. The Base Salary shall be reviewed no less frequently than annually for
    increase in the discretion of the Bank Board. Future references to base
    salary shall include any and all increases that may result from such annual
    reviews.
 
5.  BONUS AWARDS.  The Executive may receive such bonus payments for services
    performed under this Agreement as the Bank Board may award Executive from
    time to time. Such bonus payments may be in addition to, in lieu of or in
    combination with any increase in the Base Salary under Section 4. The amount
    of bonus payments for any year within the term of this Agreement shall be
    within the discretion of the Bank Board, but in no event less than a formula
    percentage applicable to other executives and employees.
 
6.  EMPLOYEE BENEFIT PROGRAMS.  During the term of this Agreement, Executive
    shall be entitled to participate in all employee pension and welfare benefit

    Performance Incentive Compensation Plan or other pension, profit-sharing
    plans and retirement plans, medical, dental, hospitalization, short-term and
    long-term disability and life insurance plans, and any other employee
    welfare benefit plans or programs that may be sponsored by Company and/or
    Bank for Bank senior level executives or employees generally from time to
    time, including any plans that supplement the above-listed types of plans or
    programs, whether funded or unfunded.
 
7.  REIMBURSEMENT OF BUSINESS AND OTHER EXPENSES.  The Executive is authorized
    to incur reasonable expenses in carrying out his duties and responsibilities

8.  TERMINATION OF EMPLOYMENT.  During the term of this agreement, the
    termination of Executive shall be processed as follows:
 
    a)  TERMINATION FOR CAUSE.
 
         i) A termination for Cause shall not take effect unless Executive shall
            be given written notice by the Bank Board of his termination for
            Cause, such notice to state in detail the particular act or acts or
            failure or failures to act that constitute the grounds on which the
            proposed termination for Cause is based.
 
         ii) In the event Executive's employment is terminated for Cause, he
             shall be entitled to:
 
           A) the Base Salary through the date of the termination of his
               employment for Cause;
 
           B) any bonus awarded or earned, but not yet paid to Executive under
               Section 5 for the year ending prior to the termination of
               Executive's employment;
 
           C) any amounts earned, accrued or owing but not yet paid under
               Sections 6 or 7 of this Agreement; and
 
           D) other or additional benefits in accordance with applicable plans
               or programs of Company and/or Bank.
 
                                       2
<PAGE>
        iii) Anything herein to the contrary notwithstanding, if following a
             termination of Executive's employment for Cause as defined in
             Section 26(d)(i) such conviction is overturned in a final
             determination on appeal, Executive shall be entitled to the
             payments and the economic equivalent of the benefits Executive
             would have received under the provisions of the Agreement if his
             employment had been terminated by Company without Cause.
 
    b)  TERMINATION WITHOUT CAUSE OR CONSTRUCTIVE TERMINATION WITHOUT
       CAUSE.  If, subsequent to the occurrence of:
 
           Y) any public announcement by another entity of its intention to
               engage in any activity which, if successful, would lead to a
               Change of Control of Company or Bank; or
 
           Z) the signing of any agreement by Company or Bank incidental to any
               proposed transaction which, upon completion, would result in a
               Change of Control of Company or Bank,
 
       the Executive(1)s employment is terminated without Cause, other than due
       to Disability or Death, or in the event there is a Constructive
       Termination Without Cause, Executive shall be entitled to:
 
         i) the Base Salary (or in the event a reduction in Base Salary is the
            basis for a Constructive Termination Without Cause, then the Base
            Salary in effect immediately prior to such reduction) to the date of
            termination of Executive's employment; plus
 
           A) continuation of the Base Salary (or in the event a reduction in
               Base Salary is the basis for a Constructive Termination Without
               Cause, then the Base Salary in effect immediately prior to such
               reduction) through the expiration of this Agreement; or
 
           B) in the event employment is terminated prior to September 30, 1998,
               continuation of the Base Salary for a period of twelve months;
 
         ii) any bonus awarded or earned, but not yet paid, to Executive under
             Section 5 of this Agreement for the year ending prior to the date
             of termination of Executive's employment;
 
        iii) payment for any accrued but unused vacation pay;
 
        iv) any amounts earned, accrued or owing but not yet paid under Sections
            6 or 7 of this Agreement;
 
         v) continued participation in all medical, dental, hospitalization and
            life insurance coverage and in other employee benefit plans in which
            he was participating on the date of the termination of his
            employment until the earlier of:
 
           A) the end of the period for which he is receiving salary
               continuation payments; or
 
           B) the date, or dates, he becomes eligible to participate in the
               benefit plans and programs of a subsequent employer (such
               coverages and benefits to be determined on a coverage-
               by-coverage, or benefit-by-benefit, basis);
 
           PROVIDED, that (x) if Executive is precluded from continuing his
           participation in any employee benefit plan or program as provided in
           this clause (v) of this Section 8(b), he shall be provided with the
           after-tax economic equivalent of the benefits provided under the plan
           or program in which he is unable to participate for the period
           specified in this clause (vi) of this Section 8(b), (y) the economic
           equivalent of any benefit foregone shall be deemed to be the lowest
           cost that would be incurred by Executive in obtaining such benefit
           himself on an individual basis, and (z) payment of such after-tax
           economic equivalent shall be made quarterly in advance; and
 
        vi) other or additional benefits in accordance with applicable plans of
            Company and/or Bank.
 
                                       3
<PAGE>
    c)  TERMINATION DUE TO DISABILITY.  In the event Executive(1)s employment is
       terminated due to his Disability, he shall be entitled to receive all
       benefits provided under Section 8 (b) of this Agreement, or the benefits
       under the then current Company, or Bank, Disability Benefit Plan,
       whichever provides the greatest economic benefit to Executive.
 
    d)  TERMINATION DUE TO DEATH.  In the event Executive's employment is
       terminated due to his Death, his estate or his beneficiaries, as the case
       may be, shall be entitled to:
 
         i) Base Salary through the date of Death and for an additional period
            of ninety (90) days following the date of Death:
 
         ii) any bonus awarded or earned, but not yet paid, to Executive under
             Section 5 for the year ending prior to the date of termination of
             Executive's employment;
 
        iii) payment for any accrued but unused vacation pay; and
 
        iv) any amounts earned, accrued or owing, but not yet paid under
            Sections 6 or 7 of this Agreement.
 
    e)  VOLUNTARY TERMINATION.  If, during the term of this agreement, Executive
       terminates his employment on his own initiative, other than a termination
       due to Death or Disability or a Constructive Termination Without Cause,
       Executive shall have the same entitlements as provided in Section
       8(a)(ii) for a termination for Cause. A voluntary termination under this
       Section 8(e) shall be effective upon six months written notice to Company
       and shall not be deemed a breach of this Agreement. If Executive fails to
       provide such notice, he shall forfeit any and all claims to any bonus,
       incentive compensation or other financial benefit that otherwise may have
       been payable during or at the expiration of the six month period.
 
    f)  NATURE OF PAYMENTS.  Any amounts due under this Section 8 are in the
       nature of severance payments considered to be reasonable by all Parties
       and are not in the nature of a penalty, and shall be paid under the
       normal pay practices of the Bank until expired.
 
9.  COMPETING WITH COMPANY OR BANK.  Executive acknowledges his familiarity and
    understanding of the Company's Statement of Policy Concerning Code of
    Conduct with Respect to Confidentiality, Inside Information and Conflicts of
    Interest and, in conformance with such policy, agrees to the following:
 
    a)  CONFIDENTIALITY.  Executive agrees that all contracts, prices, business
       practices, secrets, existing or prospective customer lists or files,
       advertising strategies, employee records, payroll, benefit and other
       compensation data, or any proprietary information or knowledge which
       Executive has or will acquire while in the employ of Company or Bank with
       respect to the business of Company or Bank is strictly confidential and
       may not be disclosed, used or exploited by Executive for his personal
       benefit or for the benefit of any other person, firm or corporation
       during his employment by Company or Bank or subsequent thereto, without
       limitation as to time. Executive agrees not to disclose any such
       information except as required by government process or court of
       competent jurisdiction.
 
    b)  EMPLOYEE AND CUSTOMER RELATIONSHIPS.  During the term of this Agreement
       and for an additional period equal to the number of months, if any,
       Executive is entitled to payment under Section 8 of this Agreement, or
       twelve months, whichever shall last occur, Executive shall not:
 
         i) advise, suggest, encourage, solicit, or otherwise attempt to induce
            any employee of Company or Bank to terminate his or her employment
            relationship with Company or Bank; nor
 
         ii) directly or indirectly solicit, contact or communicate with any
             customers or clients of Company or Bank with respect to providing
             such customers or clients any of the products or services (the
             "Business") offered by Bank, nor
 
                                       4
<PAGE>
        iii) directly or indirectly, for himself or on behalf of any other
             person, firm or corporation, otherwise attempt to divert, influence
             or take away any of Bank's customers or in any way cause Bank's
             customers to discontinue or decrease the scope of Business they
             conduct with Bank;
 
    c)  DIRECT BUSINESS COMPETITORS.  In further consideration of the payments
       and benefits provided under this Agreement, during the term of this
       Agreement and for an additional period equal to the number of months
       remaining, if any, Executive is entitled to payment under Section 8 of
       this Agreement, or twelve months, whichever shall last occur, Executive
       shall not be employed directly or indirectly by, or act as a consultant
       to, any person or entity that is or is about to be engaged in any
       business located in Clark or Floyd Counties, Indiana, or any Indiana
       counties contiguous thereto, that is or is about to be engaged (i) in the
       solicitation or acceptance of deposits; (ii) the solicitation or making
       of loans; (iii) the provision of financial advisory services, or (iv) any
       other activities that now or hereafter during the period covered by this

       associations, mortgage loan companies, consumer finance companies, credit
       unions, bank holding companies or savings and loan holding companies.
 
10. MITIGATION AND OFFSET.  In the event of any termination of employment under

    seek other employment and there shall be no offset against amounts due
    Executive under this Agreement on account of any remuneration attributable
    to any subsequent employment that he may obtain, provided such subsequent
    employment or other action of Executive does not violate any provision of
    Section 9 of this Agreement. With respect to a violation of any provision of
    Section 9 by Executive, amounts payable to Executive as provided under
    Section 8(b) shall immediately cease without prejudice to any other rights
    or causes of action that the Company or Bank may have as a result of a
    violation of any provision of Section 9 of this Agreement.
 
11. EFFECT OF AGREEMENT ON OTHER BENEFITS.  Except as specifically provided in
    this Agreement, the existence of this Agreement shall not prohibit or
    restrict Executive(1)s entitlement to full participation in employee benefit
    and other plans in which other officers of Bank are customarily eligible to
    participate.
 
12. ASSIGNABILITY; BINDING NATURE.  This Agreement shall be binding upon and
    inure to the benefit of the Parties and their respective successors, heirs
    (in the case of Executive) and assigns. No rights or obligations of Company
    or Bank under this Agreement may be assigned or transferred by Company or
    Bank except that such rights or obligations may be assigned or transferred
    pursuant to a merger or consolidation in which Company or Bank is not the
    continuing entity, or the sale or liquidation of all or substantially all of
    the assets of Company or Bank, provided that the assignee or transferee is
    the successor to all or substantially all of the assets of Company or Bank,
    and such assignee or transferee assumes the liabilities, obligations and
    duties of Company and Bank, as contained in this Agreement, either
    contractually or as a matter of law. The Company and Bank further agree
    that, in the event of a sale of assets or liquidation as described in the
    preceding sentence, each shall take whatever action it legally can to cause
    such assignee or transferee to expressly assume the liabilities, obligations
    and duties of Company and Bank hereunder. No rights or obligations of
    Executive under this Agreement may be assigned or transferred by Executive
    other than his rights to compensation and benefits, which may be transferred
    only by will or operation of law, except as provided in Section 18.
 
13. REPRESENTATION.  The Company represents and warrants that Company and Bank
    are each fully authorized and empowered to enter into this Agreement and
    that the performance of obligations under this Agreement will not violate
    any agreement between either of them and any other person, firm or
    organization.

    agreement between the Parties concerning the subject matter hereof and
    supersedes all prior agreements, understandings, discussions, negotiations
    and undertakings, whether written or oral, between the Parties with respect
    thereto.
 
15. AMENDMENT OR WAIVER.  No provision in this Agreement may be amended unless
    such amendment is agreed to in writing and signed by Executive and an
    authorized officer of Company and Bank. No waiver by any Party or any breach
    by another Party of any condition or provision contained in this Agreement
    to be performed by such other Party shall be deemed a waiver of a similar or
    dissimilar condition or provision at the same or any prior or subsequent
    time. Any waiver must be in writing and signed by the Executive or an
    authorized officer of Company or Bank, as the case may be.
 
16  SEVERABILITY.  In the event that any provision or portion of this Agreement
    shall be determined to be invalid or unenforceable for any reason, in whole
    or in part, the remaining provisions of this Agreement shall be unaffected
    thereby and shall remain in full force and effect to the fullest extent
    permitted by law.
 
17. SURVIVORSHIP.  The respective rights and obligations of the Parties
    hereunder shall survive any termination of Executive's employment to the

    where appropriate, to refer to his beneficiary, estate or other legal
    representative.
